This Pooling and Servicing
Agreement is dated and effective as of November 1, 2017, among Credit Suisse Commercial Mortgage Securities Corp., as Depositor,
KeyBank National Association, as Master Servicer, CWCapital Asset Management LLC, as Special Servicer, Wells Fargo Bank, National
Association, as Certificate Administrator and as Trustee, and Park Bridge Lender Services LLC, as Operating Advisor and as Asset

PRELIMINARY STATEMENT:


 


The Depositor intends
to sell commercial mortgage pass-through certificates (collectively, the “Certificates”), to be issued hereunder
in multiple classes (each, a “Class”), which in the aggregate will evidence the entire beneficial ownership
interest in the Trust to be created hereunder, the primary assets of which will be a pool of commercial mortgage loans and two
separate trust subordinate companion loans interest in related commercial mortgage loans. As provided herein, the Certificate Administrator
shall elect or shall cause an election to be made to treat designated portions of the Trust (exclusive of the Excess Interest and
the proceeds thereof in the Excess Interest Distribution Account) for federal income tax purposes as four separate real estate
mortgage investment conduits (the “Upper-Tier REMIC”, the “Lower-Tier REMIC”, the “Y&L
Towers Trust Subordinate Companion Loan REMIC” and the “Standard Highline Trust Subordinate Companion Loan REMIC”,
each a “Trust REMIC” as described herein).


 


In addition, the parties
intend that the portions of the issuing entity consisting of the Specific Grantor Trust Assets and the ARD Grantor Trust Assets
will be treated as a grantor trust (the “Grantor Trust”) for federal income tax purposes under subpart E,
part I of subchapter J of the Code. Each Class of Certificates other than the Class R Certificates will represent
undivided beneficial interests in the portion of the Grantor Trust consisting of the Specific Grantor Trust Assets with the corresponding
alphabetical or alphanumeric designation. As provided herein, the Certificate Administrator shall take all actions expressly required
hereunder to ensure that the portion of the Trust Fund consisting of the Grantor Trust maintains its status as a grantor trust
under federal income tax law and not be treated as part of the Trust REMICs.


 


The Depositor intends
to sell the Certificates to the Underwriters, the Initial Purchasers and the Loan-Specific Initial Purchasers.

of foreclosure and will issue the Class LUES-A, Class LUES-B, Class LUES-C and Class LUES-D Uncertificated
Interests as the “regular interests” in the Y&L Towers Trust Subordinate Companion Loan REMIC (the “Y&L
Towers Trust Subordinate Companion Loan REMIC Regular Interests”) and the uncertificated Class UES-R Interest, which
is the sole class of residual interests in the Y&L Towers Trust Subordinate Companion Loan REMIC and is represented by the
Class R Certificates. Any Y&L Towers Trust Subordinate

The Holders of the Y&L
Towers Loan-Specific Certificates shall only be entitled to receive distributions in respect of, and shall only incur losses with

the Certificates other than the Y&L Towers Loan-Specific Certificates. No Class of Certificates (other than the Y&L Towers

The Standard Highline

on the related Mortgage Loan or Serviced Whole Loan, as applicable, not reimbursed from proceeds of such Mortgage Loan or Serviced

until such time as such Appraisal or valuation referred to above is received by the Special Servicer. The Appraisal Reduction Amount
shall be calculated as of the first Determination Date that is at least ten (10) Business Days after the later of (i) the Special
Servicer’s receipt of such Appraisal and (ii) the date of the related Appraisal Reduction Event. The Master Servicer shall

four (4) Business Days of the Special Servicer’s reasonable request; provided, however, that the Special Servicer’s

of the definition of


 



     -15-


     


    

 


Appraisal Reduction Event, the Special Servicer shall order and use reasonable efforts to receive such Appraisal
within the one hundred twenty (120) day period set forth in such clause (i), and with respect to an Appraisal Reduction
Event as set forth in clause (vi) of the definition of Appraisal Reduction Event, the Special Servicer shall order and use
reasonable efforts to receive such Appraisal within the ninety (90) day period or one hundred twenty (120) day period, as applicable,
set forth in such clause (vi); provided, further, however, that in no event shall the Special Servicer
be required to order any such Appraisal prior to the conclusion of such sixty (60), ninety (90), or one hundred twenty (120) day
period, as applicable, and in each case, the related Appraisal shall be promptly delivered in electronic format by the Special
Servicer to the Master Servicer, the Directing Holder (but only prior to the occurrence and continuance of a Consultation Termination
Event and other than in the case of an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing
Certificateholder, the holder of the majority of the Controlling Class), the Operating Advisor, the Certificate Administrator and
the Trustee. In connection with any Appraisal Reduction Amount, the Master Servicer shall provide the Special Servicer with the
information as set forth above and in Section 4.05(c). The Master Servicer will not calculate Appraisal Reduction Amounts.


 


With respect to any Appraisal
Reduction Amount calculated for purposes of determining the existence and identity of the Controlling Class pursuant to Section 4.05(a)
hereof, the Appraised Value for the related Mortgaged Property determined in connection with clause (b)(i)(A)(1) or
clause (b)(i)(A)(2) of the first paragraph of this definition shall be determined on an “as-is” basis.


 


Notwithstanding anything
herein to the contrary, the aggregate Appraisal Reduction Amount related to a Mortgage Loan or Trust Subordinate Companion Loan,
as the case may be, or the related REO Property will be reduced to zero as of the date on which such Mortgage Loan or Trust Subordinate
Companion Loan, as the case may be, is paid in full, liquidated, repurchased or otherwise removed from the Trust or as otherwise
set forth in Section 4.05(d).


 


Any Appraisal Reduction
Amount in respect of a Non-Serviced Whole Loan shall be calculated by the applicable party under and in accordance with and pursuant
to the terms of the applicable Non-Serviced PSA.


 


Any Appraisal Reduction
Amount with respect to the Yorkshire & Lexington Towers Whole Loan will be allocated first to the Y&L Towers Trust

to zero by such related Appraisal Reduction Amounts), then to the Standard Highline Trust Subordinate Companion

without regard to clause (ii) above, the aggregate amount of Prepayment Interest Shortfalls with respect to such Mortgage
Loan, otherwise described in clause (i) above in connection with such Prohibited Prepayments.

Repayment Date), minus the related Administrative Cost Rate; provided, however, that for purposes of calculating
Pass-Through Rates, the Net Mortgage Rate for any Mortgage Loan or Trust Subordinate Companion Loan will be determined without
regard to any modification, waiver or amendment of the terms of the related Mortgage Loan or Trust Subordinate Companion Loan,
whether agreed to by the Master Servicer, the Special Servicer, a Non-Serviced Master Servicer or a Non-Serviced Special Servicer
or resulting from a bankruptcy, insolvency or similar proceeding involving the Mortgagor or otherwise; provided, further,
that for any Mortgage Loan or Trust Subordinate Companion Loan that does not accrue interest on the basis of a 360-day year consisting
of twelve 30-day months, then, solely for purposes of calculating Pass-Through Rates and the WAC Rates on the Regular Certificates,
the Net Mortgage Rate of such Mortgage Loan or Trust Subordinate Companion Loan for any one-month period preceding a related Due
Date will be the annualized rate at which interest would have to accrue in respect of such Mortgage Loan or Trust Subordinate Companion
Loan on the basis of a 360-day year consisting of twelve 30-day months in order to produce the aggregate amount of interest actually
accrued in respect of such Mortgage Loan or Trust Subordinate Companion Loan during such one-month period at the related Net Mortgage
Rate; provided, further, that, with respect to each Actual/360 Mortgage Loan or Trust Subordinate Companion Loan,
the Net Mortgage Rate for the one-month period (A) preceding the Due Dates that occur in January and February in any year which
is not a leap year or preceding the Due Date that occurs in February in any year which is a leap year (in any event, unless the
related Distribution Date is the final Distribution Date), will be determined exclusive of any Withheld Amounts in respect of such
Actual/360 Mortgage Loan, and (B) preceding the Due Date in March (or February, if the related Distribution Date is the final Distribution
Date), will be determined inclusive of the Withheld Amounts in respect of such Actual/360 Mortgage Loan for the immediately preceding
January and/or February, if applicable. With respect to any REO Loan, the Net Mortgage Rate shall be calculated as described above,
determined as if the predecessor Mortgage Loan or Trust Subordinate Companion Loan had remained outstanding.


 


“Net Operating
Income”: With respect to any Mortgaged Property, for any Mortgagor’s fiscal year end, Net Operating Income will
be calculated in accordance with the standard definition of “Net Operating Income” approved from time to time endorsed
and put forth by the CREFC®.

“Non-Book Entry
Certificates”: As defined in Section 5.02(c).


 


“Nonrecoverable
Advance”: Any Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance.


 


“Nonrecoverable
P&I Advance”: Any P&I Advance previously made or proposed to be made in respect of a Mortgage Loan (including
any Non-Serviced Mortgage Loan), Trust Subordinate Companion Loan or REO Loan (including any portion of an REO Loan related to
a Trust Subordinate Companion Loan, but excluding any portion of an REO Loan related to any other Companion Loan) which the Master
Servicer, in accordance with the Servicing Standard, or the Trustee, in its good faith business judgment, as applicable, determines
would not be ultimately recoverable, together with any accrued and unpaid interest thereon at the Reimbursement Rate, from Late
Collections or any other recovery on or in respect of such Mortgage Loan, Trust Subordinate Companion Loan or REO Loan; provided,
however, that the Special Servicer may, at its option (with respect to any Specially Serviced Loan and prior to the occurrence
of a Consultation Termination Event (other than with respect to any applicable Excluded Loan) in consultation with the Directing
Certificateholder) make a determination in accordance with the Servicing Standard, that any P&I Advance previously made or
proposed to be made is a Nonrecoverable P&I Advance and shall deliver to the Master Servicer (and with respect to a Serviced
Mortgage Loan, to any Other Servicer, and, with respect to a Non-Serviced Mortgage Loan, to the related Non-Serviced Master Servicer
and Non-Serviced Special Servicer), the Certificate Administrator, the Trustee, the Operating Advisor and the 17g-5 Information
Provider notice of such determination. Any such determination may be conclusively relied upon by, and shall be binding upon, the
Master Servicer and the Trustee, provided, however, that the Special Servicer shall not have such obligation to make
an affirmative determination that any P&I Advance is or would be recoverable and in the absence of a determination by the Special
Servicer that such P&I Advance is or would be a Nonrecoverable P&I Advance, such decision shall remain with the Master
Servicer or Trustee, as applicable. If the Special Servicer makes a determination that only a portion, and not all, of any previously
made or proposed P&I Advance is a Nonrecoverable P&I Advance, the Master Servicer and the Trustee shall have the right
to make its own subsequent determination that any remaining portion of any such previously made or proposed P&I Advance is
a Nonrecoverable P&I Advance. With respect to any Non-Serviced Whole Loan, if any Non-Serviced Master Servicer or Non-Serviced
Special Servicer, as applicable, in connection with a securitization of the related Non-Serviced Companion Loan determines that
a principal and interest advance with respect to the related Non-Serviced Companion Loan, if made, would be a “nonrecoverable
P&I advance”, such determination shall not be binding on the Master Servicer and the Trustee as it relates to any proposed
P&I Advance with respect to the related Non-Serviced Mortgage Loan. Similarly, with respect to the related Non-Serviced Mortgage
Loan, if the Master Servicer, the Special Servicer or the Trustee, as applicable, determines that any P&I Advance with respect
to a related Non-Serviced Mortgage Loan, if made, would be a Nonrecoverable P&I Advance, such determination shall not be binding
on the related Non-Serviced Master Servicer and related Non-Serviced Trustee as it relates to any proposed P&I Advance with
respect to the related Non-Serviced Companion Loan (unless the related Non-Serviced PSA provides otherwise). In making such recoverability
determination, the Master Servicer, the Special Servicer or the Trustee, as applicable, will be entitled (a) to consider (among
other things) (i) the obligations of the Mortgagor under the terms of the related Mortgage Loan or Companion Loan as it may have


 



     -100-


     


    

 


been modified and (ii) the related Mortgaged Properties in their “as-is” or then-current conditions and occupancies,
as modified by such party’s assumptions (consistent with the Servicing Standard in the case of the Master Servicer or the
Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) regarding
the possibility and effects of future adverse changes with respect to such Mortgaged Properties, (b) to estimate and consider (among
other things) future expenses, (c) to estimate and consider (consistent with the Servicing Standard in the case of the Master Servicer
and the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee)
(among other things) the timing of recoveries, and (d) to give due regard to the existence of any Nonrecoverable Advances which,
at the time of such consideration, the recovery of which are being deferred or delayed by the Master Servicer or the Trustee because
there is insufficient principal available for such recovery, in light of the fact that related proceeds are a source of recovery
not only for the Advance under consideration but also a potential source of recovery for such delayed or deferred Advance. In addition,
any Person, in considering whether a P&I Advance is a Nonrecoverable Advance, will be entitled to give due regard to the existence
of any outstanding Nonrecoverable Advance or Workout-Delayed Reimbursement Amount with respect to other Mortgage Loans, the Y&L
Towers Trust Subordinate Companion Loan or the Standard Highline Trust Subordinate Companion Loan, the reimbursement of which,
at the time of such consideration, is being deferred or delayed by the Master Servicer or the Trustee because there is insufficient
principal available for such reimbursement, in light of the fact that proceeds on the related Mortgage Loan or Trust Subordinate
Companion Loan, as the case may be, are a source of reimbursement not only for the P&I Advance under consideration, but also
as a potential source of reimbursement of such Nonrecoverable Advance or Workout-Delayed Reimbursement Amounts which are or may
be being deferred or delayed. In addition, any such Person may update or change its recoverability determinations at any time (but
not reverse any other Person’s determination that an Advance is a Nonrecoverable Advance) and, consistent with the Servicing
Standard, in the case of the Master Servicer or in its good faith business judgment in the case of the Trustee (solely in its capacity
as Trustee), may obtain at the expense of the Trust any reasonably required analysis, Appraisals or market value estimates or other
information for making a recoverability determination. Absent bad faith, the Master Servicer’s, the Special Servicer’s
or the Trustee’s determination as to the recoverability of any P&I Advance shall be conclusive and binding on the Certificateholders.
The determination by the Master Servicer, the Special Servicer or the Trustee, as applicable, that the Master Servicer or the Trustee,
as applicable, has made a Nonrecoverable P&I Advance or that any proposed P&I Advance, if made, would constitute a Nonrecoverable
P&I Advance, or any updated or changed recoverability determination, shall be evidenced by an Officer’s Certificate delivered
by either the Special Servicer or the Master Servicer to the other and to the Trustee, the Certificate Administrator and the Directing
Certificateholder (but in the case of the Directing Certificateholder, only prior to the occurrence and continuance of a Consultation
Termination Event and only with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than an Excluded Loan as
to such party) (and, in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced
Master Servicer, as applicable), the Operating Advisor (but only in the case of the Special Servicer), the Depositor, or by the
Trustee to the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor (and, in the case of a Serviced Mortgage
Loan or Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced Master Servicer, as applicable) and the Certificate Administrator.
The Officer’s


 



     -101-


     


    

 


Certificate shall set forth such determination of nonrecoverability and the considerations of the Master Servicer,
the Special Servicer or the Trustee, as applicable, forming the basis of such determination (which shall be accompanied by, to
the extent available, income and expense statements, rent rolls, occupancy status, property inspections and any other information
used by the Master Servicer, the Special Servicer or the Trustee, as applicable, to make such determination and shall include any
existing Appraisal of the related Mortgaged Property). The Trustee shall be entitled to conclusively rely on the Master Servicer’s
or Special Servicer’s determination that a P&I Advance is or would be nonrecoverable, and the Master Servicer shall be
entitled to conclusively rely on the Special Servicer’s determination that a P&I Advance is or would be nonrecoverable,
which determination shall be binding on the Master Servicer and the Trustee. In the case of a cross-collateralized Mortgage Loan
(if any), such recoverability determination shall take into account the cross-collateralization of the related cross-collateralized
Mortgage Loan.


 


“Nonrecoverable
Servicing Advance”: Any Servicing Advance previously made or proposed to be made in respect of a Mortgage Loan (other
than a Non-Serviced Mortgage Loan), Whole Loan or REO Property which the Master Servicer, the Special Servicer, in each case in
accordance with the Servicing Standard, or the Trustee, in its good faith business judgment, as applicable, determines would not
be ultimately recoverable, together with any accrued and unpaid interest thereon, at the Reimbursement Rate, from Late Collections
or any other recovery on or in respect of such Mortgage Loan, Whole Loan or REO Property. In making such recoverability determination,
such Person will be entitled (a) to consider (among other things) (i) the obligations of the Mortgagor under the terms of the related
Mortgage Loan or Companion Loan, as applicable, as it may have been modified and (ii) the related Mortgaged Properties in their
“as-is” or then-current conditions and occupancies, as modified by such party’s assumptions (consistent with
the Servicing Standard in the case of the Master Servicer or the Special Servicer or in its good faith business judgment in the
case of the Trustee, solely in its capacity as Trustee) regarding the possibility and effects of future adverse change with respect
to such Mortgaged Properties, (b) to estimate and consider (among other things) future expenses, (c) to estimate and consider (consistent
with the Servicing Standard in the case of the Master Servicer or the Special Servicer or in its good faith business judgment in
the case of the Trustee, solely in its capacity as Trustee) (among other things) the timing of recoveries and (d) give due regard
to the existence of any Nonrecoverable Advances that, at the time of such consideration, the recovery of which are being deferred
or delayed by the Master Servicer or the Trustee because there is insufficient principal available for such reimbursement, in light
of the fact that Related Proceeds are a source of recovery not only for the Advance under consideration but also a potential source
of recovery for such delayed or deferred Advance. In addition, any Person, in considering whether a Servicing Advance is a Nonrecoverable
Servicing Advance, will be entitled to give due regard to the existence of any Nonrecoverable Advance or Workout-Delayed Reimbursement
Amounts with respect to other Mortgage Loans, the reimbursement of which, at the time of such consideration, is being deferred
or delayed by the Master Servicer, in light of the fact that proceeds on the related Mortgage Loan are a source of recovery not
only for the Servicing Advance under consideration, but also as a potential source of recovery of such Nonrecoverable Advance or
Workout-Delayed Reimbursement Amounts which are or may be being deferred or delayed; provided, however, that if the
Workout-Delayed Reimbursement Amount relates to a Servicing Advance for the Yorkshire & Lexington Towers Whole Loan or The
Standard Highline NYC Whole Loan, the Master Servicer will be entitled to recover such


 



     -102-


     


    

 


Workout-Delayed Reimbursement Amount from
general collections on deposit in the Collection Account for the mortgage pool including the related Yorkshire & Lexington
Towers Mortgage Loan or The Standard Highline NYC Mortgage Loan. In addition, any such Person may update or change its recoverability
determinations at any time (but not reverse any other Person’s determination that an Advance is a Nonrecoverable Advance)
and, consistent with the Servicing Standard, in the case of the Master Servicer or in its good faith business judgment in the case
of the Trustee (solely in its capacity as Trustee), may obtain at the expense of the Trust any reasonably required analysis, Appraisals
or market value estimates or other information for making a recoverability determination. The determination by the Master Servicer,
the Special Servicer or the Trustee, as the case may be, that it has made a Nonrecoverable Servicing Advance or that any proposed
Servicing Advance, if made, would constitute a Nonrecoverable Servicing Advance, or any updated or changed recoverability determination,
shall be evidenced by an Officer’s Certificate delivered by either of the Special Servicer or the Master Servicer to the
other and to the Trustee, the Certificate Administrator, the Directing Certificateholder (but in the case of the Directing Certificateholder,
only prior to the occurrence and continuance of a Consultation Termination Event and only with respect to any Mortgage Loan or
Trust Subordinate Companion Loan other than an Excluded Loan as to such party) (and in the case of a Serviced Mortgage Loan or
Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced Master Servicer, as applicable), the Operating Advisor (but only
in the case of the Special Servicer) and the Depositor, or by the Trustee to the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor and the Certificate Administrator (and in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan,
any Other Servicer or Non-Serviced Master Servicer, as applicable); provided, however, that the Special Servicer
may, at its option (with respect to any Specially Serviced Loan and prior to the occurrence of a Consultation Termination Event
(other than with respect to any applicable Excluded Loan) in consultation with the Directing Certificateholder), make a determination
in accordance with the Servicing Standard, that any Servicing Advance previously made or proposed to be made is a Nonrecoverable
Servicing Advance and shall deliver to the Master Servicer (and with respect to a Serviced Mortgage Loan, to any Other Servicer),
the Trustee, the Operating Advisor, the Certificate Administrator and the 17g-5 Information Provider notice of such determination.
Any such determination may be conclusively relied upon by, and shall be binding upon, the Master Servicer, the Special Servicer
and the Trustee, provided, however, that the Special Servicer shall not have such obligation to make an affirmative
determination that any Servicing Advance is or would be recoverable and in the absence of a determination by the Special Servicer
that such Servicing Advance is or would be a Nonrecoverable Servicing Advance, such decision shall remain with the Master Servicer
or the Trustee, as applicable. If the Special Servicer makes a determination that only a portion, and not all, of any previously
made or proposed Servicing Advance is a Nonrecoverable Servicing Advance, the Master Servicer and the Trustee shall each have the
right to make its own subsequent determination that any remaining portion of any such previously made or proposed Servicing Advance
is a Nonrecoverable Servicing Advance. The Officer’s Certificate shall set forth such determination of nonrecoverability
and the considerations of the Master Servicer, the Special Servicer or the Trustee, as applicable, forming the basis of such determination
(which shall be accompanied by, to the extent available, related income and expense statements, rent rolls, occupancy status and
property inspections, and shall include any existing Appraisal with respect to the related Mortgage Loan or Serviced Companion
Loan, as applicable, or related Mortgaged Property). The Special Servicer shall promptly furnish


 



     -103-


     


    

 


any party required to make Servicing
Advances hereunder with any information in its possession regarding the Specially Serviced Loans and REO Properties as such party
required to make Servicing Advances may reasonably request for purposes of making recoverability determinations. The Trustee shall
be entitled to conclusively rely on the Master Servicer’s or the Special Servicer’s, as the case may be, determination
that a Servicing Advance is or would be nonrecoverable, and the Master Servicer shall be entitled to conclusively rely on the Special
Servicer’s determination that a Servicing Advance is or would be nonrecoverable. Notwithstanding anything herein to the contrary,
if the Special Servicer requests that the Master Servicer make a Servicing Advance, the Master Servicer may conclusively rely on
such request as evidence that such advance is not a Nonrecoverable Servicing Advance; provided, however, that the
Special Servicer shall not be entitled to make such a request more frequently than once per calendar month with respect to Servicing
Advances other than emergency advances (although such request may relate to more than one Servicing Advance). In the case of a
cross-collateralized Mortgage Loan (if any), such recoverability determination shall take into account the cross-collateralization
of the related cross-collateralized Mortgage Loan. The determination as to the recoverability of any servicing advance previously
made or proposed to be made in respect of a Non-Serviced Whole Loan shall be made by the related Non-Serviced Master Servicer,
Non-Serviced Special Servicer or Non-Serviced Trustee, as the case may be, pursuant to the Non-Serviced PSA.

such Mortgage Loan Seller may provisionally satisfy the delivery requirements of the related Mortgage Loan Purchase Agreement
and this Section 2.01(b) with respect to such assignment by delivering to the Custodian with respect to such Mortgage Loan

the Master Servicer (in care of the Trustee, as titled above) that may be required in order for the Master Servicer to draw on
such letter of credit on behalf of the Trust in accordance with the applicable terms thereof and/or of the related Mortgage Loan

(c)       Pursuant
to each Mortgage Loan Purchase Agreement, except in the case of a Non-Serviced Mortgage Loan, the related Mortgage Loan Seller
is required at its sole cost and expense, to itself, or to engage a third party to, put each Assignment of Mortgage, each assignment
of Assignment of Leases and each assignment of each UCC Financing Statement (collectively, the “Assignments”
and, individually, “Assignment”) relating to the Mortgage Loans and Trust Subordinate Companion Loans conveyed
by it under the applicable Mortgage Loan Purchase Agreement in proper form for filing or recording, as applicable, and to submit
such Assignments for filing or recording, as the case may be, in the applicable public filing or recording office. On the Closing
Date, the Mortgage Loan Sellers may deliver one (1) omnibus assignment for all such Mortgage Loans substantially in the form of
Exhibit H hereto to the Custodian as provided in Section 2.01(b). Except under the circumstances provided for in
the last sentence of this subsection (c) and except in the case of a Non-Serviced Mortgage Loan, the related Mortgage Loan
Seller will itself, or a third party at such Mortgage Loan Seller’s expense will, promptly (and in any event within one hundred-twenty
(120) days after the later of the Closing Date and the related Mortgage Loan Seller’s actual receipt of the related documents
and the necessary recording and filing information) cause to be submitted for recording or filing, as the case may be, in the appropriate
public office for real property records or UCC Financing Statements, as appropriate, each Assignment. Each such Assignment submitted
for recording shall reflect that it (or a file copy thereof in the case of a UCC Assignment) should be returned by the public recording
office to the Custodian or its designee following recording or filing (or to the related Mortgage Loan Seller or its agent who
will then be responsible for delivery of the same to the Custodian or its designee). Any such Assignment received by the Custodian
shall be promptly included in the related Mortgage File and be deemed a part thereof, and any such Assignment received by the related
Mortgage Loan Seller or its agent shall be required to be delivered to the Custodian to be included as part of the related Mortgage
File within thirty (30) days after receipt. If any such document or instrument is determined to be incomplete or not to meet the
recording or filing requirements of the jurisdiction in which it is to be recorded or filed, or is lost by the public office or
returned unrecorded or unfiled, as the case may be, because of a defect therein, on or about one hundred-eighty (180) days after
the Closing Date, the related Mortgage Loan Seller or its designee shall prepare, at its own expense, a substitute therefor or
cure such defect, as the case may be, and thereafter the related Mortgage Loan Seller or its designee shall, at the expense of
such Mortgage Loan Seller, upon receipt thereof cause the same to be duly recorded or filed, as appropriate. If, by the first anniversary
of the Closing Date, the Custodian has not received confirmation of the recording or filing as the case may be, of any such Assignment,
it shall so advise the related Mortgage Loan Seller who may then pursue such confirmation itself or request that the Custodian
pursue such confirmation at the related Mortgage Loan Seller’s expense, and upon such a request and provision for payment
of such expenses satisfactory to the Custodian, the Custodian, at the expense of the applicable Mortgage Loan Seller, shall cause
a search of the land records of each applicable jurisdiction and of the records of the offices of the applicable Secretary of State
for confirmation that the Assignment appears in such records and retain a copy of such confirmation in the related Mortgage File.
In the event that confirmation of the recording or filing of an Assignment cannot be obtained, the Custodian or the related Mortgage
Loan Seller, as applicable, shall promptly inform the other and the Custodian shall provide such Mortgage Loan Seller with a copy
of the Assignment and request the preparation of a new Assignment. The related Mortgage Loan Seller shall pay the expenses for
the preparation of replacement Assignments for any Assignments which, having


 






     -180-


     


    

 


been
properly submitted for filing or recording to the appropriate governmental office by the Custodian, fail to appear of record and
must be resubmitted. Notwithstanding the foregoing, there shall be no requirement to record any assignment to the Trustee referred
to in clause (iii) or (v) of the definition of “Mortgage File,” or to file any UCC-3 to the Trustee
referred to in clause (ix) of the definition of “Mortgage File,” in those jurisdictions where, in the written
opinion of local counsel (which opinion shall be an expense of the related Mortgage Loan Seller) acceptable to the Depositor and
the Trustee, such recordation and/or filing is not required to protect the Trustee’s interest in the related Mortgage Loan,
against sale, further assignment, satisfaction or discharge by the related Mortgage Loan Seller, the Master Servicer, the Special
Servicer, any Sub-Servicer or the Depositor.


 


(d)       All
documents and records in the Depositor’s or the applicable Mortgage Loan Seller’s possession relating to the Mortgage
Loans and the Trust Subordinate Companion Loans (including, in each case, financial statements, operating statements and any other
information provided by the respective Mortgagor from time to time, but excluding the applicable Mortgage Loan Seller’s internal
communications (including such communications between such Mortgage Loan Seller and its Affiliates) and underwriting analysis (including
documents prepared by the applicable Mortgage Loan Seller or any of its Affiliates for such purposes), draft documents, attorney-client
communications that are privileged communications or constitute legal or other due diligence analyses and credit underwriting or
due diligence analyses or data) that (i) are not required to be a part of a Mortgage File in accordance with the definition thereof
and (ii) are reasonably necessary for the servicing of each such Mortgage Loan and Trust Subordinate Companion Loan, together with
copies of all documents in each Mortgage File, shall be delivered by the Depositor or the applicable Mortgage Loan Seller to the
Master Servicer within five (5) Business Days after the Closing Date and shall be held by the Master Servicer on behalf of the
Trustee in trust for the benefit of the Certificateholders and, if applicable, on behalf of the related Companion Holder. Such
documents and records shall be any documents and records (with the exception of any items excluded under the immediately preceding
sentence) that would otherwise be a part of the Servicing File.


 


(e)       In
connection with the Depositor’s assignment pursuant to subsection (a) above, the Depositor shall deliver to the Trustee
and the Master Servicer, on or before two (2) Business Days after the Closing Date, a fully executed original counterpart of each
of the Mortgage Loan Purchase Agreements, as in full force and effect, without amendment or modification, on the Closing Date.


 


(f)       The
Depositor shall use its reasonable best efforts to require that, promptly after the Closing Date, but in all events within three
(3) Business Days after the Closing Date, each of the Mortgage Loan Sellers shall cause all funds on deposit in escrow accounts
maintained with respect to the Mortgage Loans transferred by such Mortgage Loan Seller, whether such accounts are held in the name
of the applicable Mortgage Loan Seller or any other name to be transferred to the Master Servicer (or a Sub-Servicer) for deposit
into Servicing Accounts.


 


(g)       With
respect to the Mortgage Loan secured by the Mortgaged Property identified as “The Boulders Resort & Spa” on the
Mortgage Loan Schedule, which is subject to a franchise agreement with a related comfort letter in favor of the respective Mortgage
Loan Seller


 






     -181-


     


    

 


that
requires notice to or request of the related franchisor to transfer or assign any related comfort letter to the Trust or otherwise
have a new comfort letter issued in the name of the Trust, the related Mortgage Loan Seller or its designee will be required to
provide any such required notice or make any such required request to the related franchisor (with a copy of such notice or request
to the Master Servicer) within 45 days of the Closing Date (or any shorter period if required by the applicable comfort letter),
and the Master Servicer shall use reasonable efforts in accordance with the Servicing Standard to acquire such replacement comfort
letter, if necessary (or to acquire any such new document or acknowledgement as may be contemplated under the existing comfort
letter). If the Master Servicer is unable to acquire any such replacement comfort letter (or new document or acknowledgement,
as applicable) within one hundred twenty (120) days of the Closing Date, the Master Servicer shall notify the related Mortgage
Loan Seller that no such replacement comfort letter has been received.


 


(h)       Each
Mortgage Loan Purchase Agreement shall provide that no later than sixty (60) days after the Closing Date, each Mortgage Loan Seller
shall deliver or cause to be delivered the Diligence Files for each of its Mortgage Loans and Trust Subordinate Companion Loans
to the Depositor by uploading such Diligence Files to the Designated Site. Promptly upon completion of such delivery of the Diligence
Files (but in no event later than sixty (60) days after the Closing Date), the applicable Mortgage Loan Seller shall provide to
the Depositor a certificate (with a copy (which may be sent by email) to each of the Master Servicer, the Special Servicer, the
Trustee, the Certificate Administrator, the Custodian, the Asset Representations Reviewer and the Operating Advisor) certifying
that the electronic copies of the Diligence File uploaded to the Designated Site contain all documents and information required
under the definition of “Diligence File” and such Diligence Files are organized and categorized in accordance with
the electronic file structure reasonably agreed to by the Depositor and the Mortgage Loan Seller (the “Diligence File
Certificate”).


 


(i)       On
or before the Closing Date, the Depositor shall deliver the Initial Schedule AL File, any Initial Schedule AL Additional File and
Annex A-1 to the Prospectus in EDGAR-Compatible Format and Microsoft Excel format to the Master Servicer at KC_Investor_Reporting@KeyBank.com.


 


(j)       Notwithstanding
anything to the contrary contained in this Section 2.01 or in Section 2.02, in connection with a Servicing Shift
Whole Loan, (1) instruments of assignment to the Trustee may be in blank and need not be recorded pursuant to this Agreement (other
than the endorsements to the Note(s) evidencing the related Servicing Shift Mortgage Loan) until the earlier of (i) the related
Servicing Shift Securitization Date, in which case such instruments shall be assigned and recorded in accordance with the related
Non-Serviced PSA, (ii) 180 days following the Closing Date, and (iii) such Servicing Shift Whole Loan becoming a Specially Serviced
Loan prior to such Servicing Shift Securitization Date, in which case assignments and recordations shall be effected in accordance
with this Section 2.01 until the occurrence, if any, of such Servicing Shift Securitization Date, (2) no letter of credit
need be amended (including, without limitation, to change the beneficiary thereon) until the earlier of (i) the related Servicing
Shift Securitization Date, in which case such amendment shall be in accordance with the related Non-Serviced PSA, (ii) 180 days
following the Closing Date, and (iii) such Servicing Shift Whole Loan becoming a Specially Serviced Loan prior to such Servicing
Shift Securitization Date in which case such amendment shall be effected in accordance with the terms of this


 






     -182-


     


    

 


Section
2.01, and (3) on and following such Servicing Shift Securitization Date, the Person selling the related Servicing Shift Lead
Note to the related Non-Serviced Depositor, at its own expense, shall be (a) entitled to direct in writing, via a Request for
Release, which may be conclusively relied upon by the Custodian, the Custodian to deliver the originals of all the Mortgage Loan
documents relating to such Servicing Shift Whole Loan in its possession (other than the original Note(s) evidencing such Servicing
Shift Mortgage Loan) to the related Non-Serviced Trustee or the related Non-Serviced Custodian, (b) if the right under clause
(a) is exercised, required to cause the retention by or delivery to the Custodian of photocopies of Mortgage Loan documents
related to such Servicing Shift Whole Loan so delivered to such Non-Serviced Trustee or such Non-Serviced Custodian, (c) entitled
to cause the completion (or, in the event of a recordation as contemplated by clause (1)(ii) of this paragraph, the preparation,
execution and delivery) and recordation of instruments of assignment in the name of the related Other Trustee or related Non-Serviced
Custodian, (d) if the right under clause (c) is exercised, required to deliver to the Trustee or Custodian photocopies
of any instruments of assignment so completed and recorded, and (e) entitled to require the Master Servicer to transfer, and to
cooperate with all reasonable requests in connection with the transfer of, the Servicing File, and any Escrow Payments, reserve
funds and items specified in clauses (9), (12) (14) and (18) of the definition of “Mortgage File”
for such Servicing Shift Whole Loan to the related Other Servicer.


 


Section 2.02      Acceptance
by Trustee. (a) The Trustee, by the execution and delivery of this Agreement (1) acknowledges receipt by it or a Custodian
on its behalf, subject to the provisions of Section 2.01, in good faith and without notice of any adverse claim, of the
applicable documents specified in clause (i) of the definition of “Mortgage File” with respect to each Mortgage
Loan and Trust Subordinate Companion Loan and of all other assets included in the Trust Fund and (2) declares (a) that it or a
Custodian on its behalf holds and will hold such documents and the other documents delivered or caused to be delivered by the
Mortgage Loan Sellers that constitute the Mortgage Files in the name of the Trust for the benefit of all present and future Certificateholders,
and (b) that it holds and will hold such other assets included in the Trust Fund, in trust for the exclusive use and benefit of
all present and future Certificateholders and, with respect to any original document in the Mortgage File for a Serviced Whole
Loan, for any present or future Companion Holder (and for the benefit of the Trustee as holder of the Lower-Tier Regular Interests),
as applicable. If any Mortgage Loan Seller is unable to deliver or cause the delivery of any original Mortgage Note, such Mortgage
Loan Seller may deliver a copy of such Mortgage Note, together with a signed lost note affidavit and appropriate indemnity and
shall thereby be deemed to have satisfied the document delivery requirements of Section 2.01 and of this Section 2.02.


 


(b)       Within
sixty (60) days of the Closing Date (or with respect to a Qualified Substitute Mortgage Loan within sixty (60) days after the Due
Date in the month of substitution), the Custodian, shall review the Mortgage Loan documents delivered or caused to be delivered
by the Mortgage Loan Sellers constituting the Mortgage Files; and, promptly following such review (but in no event later than sixty
(60) days after the Closing Date), the Custodian shall, in the form attached as Exhibit Q, certify in writing to each of
the Rating Agencies, the Depositor, the Master Servicer, the Special Servicer, the Directing Holder (so long as no Consultation
Termination Event shall have occurred and be continuing and only with respect to Mortgage Loans or Trust Subordinate Companion

the Holder of the


 






     -183-


     


    

 


majority
of the Controlling Class), the Operating Advisor, the Asset Representations Reviewer and the applicable Mortgage Loan Seller (as
to each Mortgage Loan (or Trust Subordinate Companion Loan) listed in the Mortgage Loan Schedule (other than any Mortgage Loan
or Trust Subordinate Companion Loan paid in full)) that, except as specifically identified in any exception report annexed to
such writing (the “Custodial Exception Report”), (i) subject to the final proviso of the definition of “Mortgage
File” herein and Section 2.01 hereof, all documents specified in clauses (i) through (v), (viii),
(ix), (xi), (xii) and (xiii) (or, with respect to clause (xii), a copy of such letter of credit
and the required Officer’s Certificate), if any, of the definition of “Mortgage File”, as applicable, are in
its possession, (ii) the foregoing documents delivered or caused to be delivered by the Mortgage Loan Sellers have been reviewed
by the Custodian and appear regular on their face and appear to be executed and to relate to such Mortgage Loan or Trust Subordinate
Companion Loan, and (iii) based on such examination and only as to the foregoing documents, the information set forth in the Mortgage
Loan Schedule with respect to the items specified in clauses (iv), (vi) and (viii)(c) in the definition of
“Mortgage Loan Schedule” is correct. With respect to each Mortgage Loan or Trust Subordinate Companion Loan listed
on the Custodial Exception Report, the Custodian shall specifically identify such Mortgage Loan or Trust Subordinate Companion
Loan together with the nature of such exception (in the form reasonably acceptable to the Custodian and the related Mortgage Loan
Seller and separating items required to be in the Mortgage File but never delivered from items which were delivered by the related
Mortgage Loan Seller but are out for filing or recording and have not been returned by the filing office or the recorder’s
office).


 


(c)       The
Custodian shall review the Mortgage Loan documents received subsequent to the Closing Date; and, on or about the first anniversary
of the Closing Date, the Custodian shall, in the form attached as Exhibit Q, certify in writing to each of the Depositor,
the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Directing Holder (so long as no Consultation
Termination Event shall have occurred and be continuing and only with respect to the Mortgage Loans, the Y&L Towers Trust Subordinate
Companion Loan or the Standard Highline Trust Subordinate Companion Loan other than any Excluded Loan with respect to the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class), the
Operating Advisor, the Asset Representations Reviewer and the applicable Mortgage Loan Seller (as to each Mortgage Loan (or the
Y&L Towers Trust Subordinate Companion Loan or the Standard Highline Trust Subordinate Companion Loan) listed on the Mortgage
Loan Schedule (other than any related Mortgage Loan as to which a Liquidation Event has occurred) or any related Mortgage Loan
or Trust Subordinate Companion Loan specifically identified in any exception report annexed to such writing) that, (i) subject
to the final proviso of the definition of “Mortgage File” herein and Section 2.01 hereof, all documents specified
in clauses (i) through (v), (viii), (ix), (xi), (xii) and (xiii), if any, of the
definition of “Mortgage File”, as applicable, are in its possession, (ii) the foregoing documents delivered or caused
to be delivered by the Mortgage Loan Sellers have been reviewed by the Custodian and appear regular on their face and appear to

to the foregoing documents, the information set forth in the Mortgage Loan Schedule with respect to the items specified in clauses
(iv), (vi) and (viii)(c) in the definition of “Mortgage Loan Schedule” is correct.


 






     -184-


     


    

 


(d)       Notwithstanding
anything contained in this Section 2.02 and Section 2.03(b) to the contrary, in the case of a Material Defect in
any of the documents specified in clauses (ii) through (v), (vii), (viii) and (ix) in the definition
of “Mortgage File”, which Material Defect results solely from a delay in the return of the related documents from the
applicable filing or recording office and gives rise to a repurchase or substitution obligation on the part of the related Mortgage
Loan Seller with respect to the subject Mortgage Loan or Trust Subordinate Companion Loan pursuant to the related Mortgage Loan
Purchase Agreement, the Directing Holder, in its sole judgment, may (other than with respect to any Excluded Loan with respect
to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, or the Holder of the majority of the Controlling
Class and, with respect to any other Mortgage Loan, only prior to the occurrence and continuance of a Control Termination Event),
and the Special Servicer may, in accordance with the Servicing Standard, after the occurrence and during the continuance of a Control
Termination Event, permit the related Mortgage Loan Seller in lieu of repurchasing or substituting for the related Mortgage Loan
or Trust Subordinate Companion Loan, to deposit with the Master Servicer an amount, to be held in trust in a segregated Eligible
Account (which may be a sub-account of the Collection Account), equal to 25% of the Stated Principal Balance of the related Mortgage
Loan or Trust Subordinate Companion Loan (in the alternative, the related Mortgage Loan Seller may deliver to the Master Servicer
a letter of credit in such amount, with a copy to the Custodian). Such funds or letter of credit, as applicable, shall be held
by the Master Servicer (i) until the date on which the Custodian determines and notifies the Master Servicer that such Material
Defect has been cured or the related Mortgage Loan or Trust Subordinate Companion Loan is no longer part of the Trust Fund, at
which time the Master Servicer shall return such funds (or letter of credit) to the related Mortgage Loan Seller, or (ii) until
same are applied to the Purchase Price (or the Substitution Shortfall Amount, if applicable) as set forth below in this Section
2.02(d) in the event of a repurchase or substitution by the related Mortgage Loan Seller. Notwithstanding the two immediately
preceding sentences, if the Master Servicer or the Special Servicer certifies to the Trustee, the Certificate Administrator and
the Custodian that it has determined in the exercise of its reasonable judgment that the document with respect to which such Material
Defect exists is required in connection with an imminent enforcement of the mortgagee’s rights or remedies under the related
Mortgage Loan or Trust Subordinate Companion Loan, defending any claim asserted by any Mortgagor or third party with respect to
the related Mortgage Loan or Trust Subordinate Companion Loan, establishing the validity or priority of any lien on collateral
securing the related Mortgage Loan or Trust Subordinate Companion Loan or for any immediate significant servicing obligation, the
related Mortgage Loan Seller shall be required to repurchase or substitute for the related Mortgage Loan or Trust Subordinate Companion
Loan in accordance with, and to the extent required by, the terms and conditions of Section 2.03(b) and Section 6 of the
related Mortgage Loan Purchase Agreement; provided, however, that such Mortgage Loan Seller shall not be required
to repurchase the Mortgage Loan or Trust Subordinate Companion Loan for a period of ninety (90) days after receipt of a notice
to repurchase (together with any applicable extension period) if it is attempting to recover the document from the applicable filing
or recording office and provides an officer’s certificate setting forth what actions such Mortgage Loan Seller is pursuing
in connection with such recovery. In the event of a repurchase or substitution, upon the date of such repurchase or substitution,
and in the event that the related Mortgage Loan Seller has delivered a letter of credit to the Master Servicer in accordance with
this Section 2.02(d), the Master Servicer shall, to the extent necessary, draw on the letter of credit and deposit the


 






     -185-


     


    

 


proceeds
of such draw, into the Collection Account to be applied to the Purchase Price (or the Substitution Shortfall Amount, if applicable,
in which event, the amount of such funds or proceeds that exceed the Substitution Shortfall Amount shall be returned to the related
Mortgage Loan Seller) in accordance with Section 2.03(b). All such funds deposited in the Collection Account shall be invested
in Permitted Investments, at the direction and for the benefit of the related Mortgage Loan Seller. Such funds shall be treated
as an “outside reserve fund” under the REMIC Provisions, which, together with any reimbursement from the Lower-Tier
REMIC, is beneficially owned by the related Mortgage Loan Seller for federal income tax purposes, which Mortgage Loan Seller shall
remain liable for any taxes payable on income or gain with respect thereto.


 


(e)       It
is herein acknowledged that neither the Trustee nor any Custodian is under any duty or obligation (i) to determine whether any
of the documents specified in clauses (vi), (vii) and (xii) through (xvii) of the definition of “Mortgage
File” exist or are required to be delivered by the Depositor, the Mortgage Loan Sellers or any other Person (unless identified
on the Mortgage Loan Checklist) or (ii) to inspect, review or examine any of the documents, instruments, certificates or other
papers relating to the Mortgage Loans or the Trust Subordinate Companion Loans delivered to it to determine that the same are genuine,
enforceable, duly authorized, sufficient to perfect and maintain the perfection of a security interest or appropriate for the represented
purpose or that they are other than what they purport to be on their face and, with respect to the documents specified in clause
(viii) of the definition of the “Mortgage File”, whether the insurance is effective as of the date of the recordation,
whether all endorsements or riders issued are included in the file or if the policy has not been issued whether any acceptable
replacement document has been dated the date of the related Mortgage Loan funding. Further, with respect to the UCC Financing Statements
referenced in the Mortgage File, absent actual knowledge to the contrary or copies of UCC Financing Statements delivered to the
Custodian as part of the Mortgage File indicating otherwise, the Custodian may assume, for the purposes of the filings and the
certification to be delivered in accordance with this Section 2.02 that the related Mortgage File should include one state
level UCC Financing Statement filing for each Mortgaged Property (or with respect to any Mortgage Loan that has two or more Mortgagors,
for each Mortgagor, except to the extent multiple Mortgagors are named as debtors in the same UCC Financing Statement filing),
or if the Custodian has received notice that a particular UCC Financing Statement was filed as a fixture filing, that the related
Mortgage File should include only a local UCC Financing Statement filing for each Mortgaged Property (or with respect to any Mortgage
Loan that has two or more Mortgagors, for each Mortgagor, except to the extent multiple Mortgagors are named as debtors in the
same UCC Financing Statement filing). The assignments of the UCC Financing Statements to be assigned to the Trust will be delivered
on the new national forms (or on such other form as may be acceptable for filing or recording in the applicable jurisdiction) and
in a format suitable for filing or recording, as applicable, and will be filed or recorded in the jurisdiction(s) where such UCC
Financing Statements were originally filed or recorded, as indicated in the documents provided, and in accordance with then-current
laws.


 


(f)       If,
in the process of reviewing the Mortgage Files or at any time thereafter, the Custodian finds any document or documents constituting
a part of a Mortgage File (1) not to have been properly executed, (2) subject to the timing requirements of Sections 2.01(b)
and 2.01(c), not to have been delivered, (3) to contain information that does not conform in any


 






     -186-


     


    

 


material
respect with the corresponding information set forth in the Mortgage Loan Schedule or (4) to be defective on its face (each, a
“Defect” in the related Mortgage File), the Custodian shall promptly so notify the Depositor, the Trustee,
the Master Servicer, the Special Servicer, the Certificate Administrator, the Directing Holder, the applicable Mortgage Loan Seller
(and in no event later than ninety (90) days after the Closing Date and every calendar quarter thereafter until all Defects are
corrected) by providing a Custodial Exception Report setting forth for each affected Mortgage Loan or Trust Subordinate Companion
Loan, with particularity, the nature of such Defect (in a form reasonably acceptable to the Custodian and such Mortgage Loan Seller
and separating items required to be in the Mortgage File but never delivered from items which were delivered by such Mortgage
Loan Seller but are out for recording or filing and have not been returned by the recorder’s office or filing office).


 


(g)       If
the Master Servicer or the Special Servicer (i) receives any request or demand for repurchase or replacement of a Mortgage Loan
or Trust Subordinate Companion Loan because of a breach of or alleged breach of a representation or warranty or a Defect (any such
request or demand for repurchase or replacement, a “Repurchase Request”, and the Master Servicer or the Special
Servicer, as applicable, to the extent it receives a Repurchase Request, the “Repurchase Request Recipient”
with respect to such Repurchase Request); or (ii) receives any withdrawal of a Repurchase Request by the Person making such Repurchase
Request or any rejection of a Repurchase Request (or such a Repurchase Request is forwarded to the Master Servicer or the Special
Servicer by another party hereto), then the Repurchase Request Recipient shall deliver notice (which may be by electronic format
so long as a “backup” hard copy of such notice is also delivered on or prior to the next Business Day) of such Repurchase
Request or withdrawal or rejection of a Repurchase Request (each, a “15Ga-1 Notice”) to the applicable Mortgage
Loan Seller (other than in the case of a rejection by such Mortgage Loan Seller) and the Depositor, in each case within ten (10)
Business Days from such Repurchase Request Recipient’s receipt thereof.


 


Each 15Ga-1 Notice shall
include (i) the identity of the related Mortgage Loan or Trust Subordinate Companion Loan, (ii) the date the Repurchase Request
is received by the Repurchase Request Recipient or the date any withdrawal of the Repurchase Request is received by the Repurchase
Request Recipient, as applicable, (iii) if known, the basis for the Repurchase Request (as asserted in the Repurchase Request)
and (iv) a statement from the Repurchase Request Recipient as to whether it currently plans to pursue such Repurchase Request.


 


A Repurchase Request
Recipient shall not be required to provide any information in a 15Ga-1 Notice protected by the attorney-client privilege or attorney
work product doctrines. The Mortgage Loan Purchase Agreements will provide that (i) any 15Ga-1 Notice provided pursuant to this
Section 2.02(g) is so provided only to assist the Mortgage Loan Sellers and Depositor or their respective Affiliates to
comply with Rule 15Ga-1 under the Exchange Act, Items 1104 and 1121 of Regulation AB and any other requirement of law or regulation
and (ii) (A) no action taken by, or inaction of, a Repurchase Request Recipient and (B) no information provided pursuant to this
Section 2.02(g) by a Repurchase Request Recipient, shall be deemed to constitute a waiver or defense to the exercise of
any legal right the Repurchase Request Recipient may have with respect to the related Mortgage Loan Purchase Agreement, including
with respect to any Repurchase Request that is the subject of a 15Ga-1 Notice.

In the event that the
Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian
receives a Repurchase Request, such party shall promptly forward or otherwise provide written notice of such Repurchase Request
to the Master Servicer, if relating to a Non-Specially Serviced Loan, or to the Special Servicer, if relating to a Specially Serviced
Loan or REO Property, and include the following statement in the related correspondence: “This is a ‘Repurchase Request’
under Section 2.02 of the Pooling and Servicing Agreement relating to the CSAIL 2017-CX10 Commercial Mortgage Trust, Commercial
Mortgage Pass-Through Certificates, Series 2017-CX10 requiring action by you as the ‘Repurchase Request Recipient’
thereunder.” Upon receipt of such Repurchase Request by the Master Servicer or the Special Servicer, as applicable, such
party shall be deemed to be the Repurchase Request Recipient in respect of such Repurchase Request, and such party shall comply
with the procedures set forth in this Section 2.02(g) with respect to such Repurchase Request. In no event shall the Custodian,
by virtue of this provision, be required to provide any notice other than as set forth in Section 2.02 of this Agreement
in connection with its review of the Mortgage File.


 


If the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian receives notice
or has knowledge of a withdrawal or a rejection of a Repurchase Request of which notice has been previously received or given,
and such notice was not received from or copied to the Master Servicer or the Special Servicer, then such party shall give notice
of such withdrawal or rejection to the Master Servicer or the Special Servicer, as applicable. Any such notice received by the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian shall also be
provided to the Depositor and, in the case of a withdrawal notice, to the applicable Mortgage Loan Seller.


 


In the event that a Mortgage
Loan or Trust Subordinate Companion Loan is repurchased or replaced pursuant to Section 2.03 of this Agreement, the Master
Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) shall
promptly notify the Depositor of such repurchase or replacement.

(b)       If
any Certificateholder, the Directing Holder, the Master Servicer, the Special Servicer, the Certificate Administrator, Operating
Advisor (solely in its capacity as Operating Advisor) or the Trustee discovers (without implying any duty of such person to make,
or to attempt to make, such a discovery) or receives notice alleging a Material Defect in any Mortgage File, such Certificateholder,
the Directing Holder, the Master Servicer, the Special Servicer, the Trustee, Operating Advisor (solely in its capacity as Operating
Advisor) or the Certificate Administrator, as applicable, shall give prompt written notice of such Material Defect to the Depositor,
the Master Servicer, the Special Servicer, the applicable Mortgage Loan Seller, the Trustee, the Certificate Administrator, the
Operating Advisor (solely in its capacity as Operating Advisor) and, prior to the occurrence of a Consultation Termination Event,
the Directing Holder, and the Master Servicer (if the related Mortgage Loan is a Non-Specially Serviced Loan) or the Special Servicer
(if the related Mortgage Loan is a Specially Serviced Loan), as applicable, shall request in writing that the applicable Mortgage
Loan Seller, not later than ninety (90) days after (i) except in the case of the succeeding clause (ii), the applicable
Mortgage Loan Seller’s discovery of the Material Defect or receipt of such notice or (ii) in the case of a Material Defect
relating to a Mortgage Loan (with respect to the Yorkshire & Lexington Towers Mortgage Loan and The Standard Highline NYC Mortgage
Loan, including


 






     -189-


     


    

 


the related Trust Subordinate Companion Loan) not being a Qualified Mortgage, the earlier of (x) the discovery
by the Mortgage Loan Seller or any party to this Agreement of such Material Defect or (y) receipt of notice of a discovery of such
Material Defect from any party to this Agreement by the Mortgage Loan Seller, (such ninety (90) day period, the “Initial
Cure Period”), (A) cure such Material Defect in all material respects, at such Mortgage Loan Seller’s own expense,
including reimbursement of any related reasonable additional expenses of the Trust reasonably incurred by any party to this Agreement,
(B) repurchase the affected Mortgage Loan, Trust Subordinate Companion Loan or REO Mortgage Loan (excluding any related Companion
Loan, if applicable) at the applicable Purchase Price and in conformity with the applicable Mortgage Loan Purchase Agreement and
this Agreement or (C) substitute a Qualified Substitute Mortgage Loan (other than with respect to any Mortgage Loan that is part
of a Whole Loan, for which no substitution will be permitted) for such affected Mortgage Loan or REO Mortgage Loan, and pay any
Substitution Shortfall Amount in connection with such substitution (provided that in no event shall any such substitution
occur on or after the second anniversary of the Closing Date) and pay the Master Servicer for deposit into the Collection Account,
any Substitution Shortfall Amount in connection therewith and in conformity with the applicable Mortgage Loan Purchase Agreement
and this Agreement; provided, however, that except with respect to a Material Defect resulting solely from the failure
by the Mortgage Loan Seller to deliver to the Trustee or Custodian the actual policy of lender’s title insurance required
pursuant to clause (viii) of the definition of Mortgage File by a date not later than eighteen (18) months following the
Closing Date, if such Material Defect is capable of being cured but is not cured within the Initial Cure Period, and the applicable
Mortgage Loan Seller has commenced and is diligently proceeding with the cure of such Material Defect within the Initial Cure Period,
the applicable Mortgage Loan Seller shall have an additional ninety (90) days commencing immediately upon the expiration of the
Initial Cure Period (such additional ninety (90) day period, the “Extended Cure Period”) to complete such cure
(or, failing such cure, to repurchase the related Mortgage Loan or REO Loan (excluding any related Serviced Companion Loan, if
applicable, except for the Trust Subordinate Companion Loans) or substitute a Qualified Substitute Mortgage Loan (other than with
respect to any Mortgage Loan that is part of a Whole Loan, for which no substitution will be permitted) and pay any Substitution
Shortfall Amount in connection with such substitution) and provided, further, that with respect to such Extended
Cure Period the applicable Mortgage Loan Seller shall have delivered an officer’s certificate to the Trustee, the Certificate
Administrator (who shall promptly deliver a copy of such officer’s certificate to the 17g-5 Information Provider), the Master
Servicer, the Special Servicer, the Operating Advisor and (with respect to any Mortgage Loan other than an Excluded Loan with respect
to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling
Class, prior to the occurrence and continuance of a Consultation Termination Event), the Directing Holder, setting forth the reason
such Material Defect is not capable of being cured within the Initial Cure Period and what actions the applicable Mortgage Loan
Seller is pursuing in connection with the cure thereof and stating that the applicable Mortgage Loan Seller anticipates that such
Material Defect will be cured within the Extended Cure Period; and provided, further, that, if any such Material
Defect is still not cured after the Initial Cure Period and any such Extended Cure Period solely due to the failure of the Mortgage
Loan Seller to have received the recorded document, then the Mortgage Loan Seller shall be entitled to continue to defer its cure,
substitution or repurchase obligations in respect of such Material Defect so long as the Mortgage Loan Seller certifies to the
Trustee, the


 






     -190-


     


    

 


Special Servicer, the Master Servicer and the Certificate Administrator every 30 days thereafter that the Material
Defect is still in effect solely because of its failure to have received the recorded document and that the Mortgage Loan Seller
is diligently pursuing the cure of such defect (specifying the actions being taken), except that no such deferral of cure, substitution
or repurchase may continue beyond the date that is 18 months following the Closing Date. Any such repurchase or substitution of
a Mortgage Loan shall be on a whole loan, servicing released basis. Notwithstanding the foregoing, any Material Defect which causes
any Mortgage Loan or Trust Subordinate Companion Loan not to be a Qualified Mortgage shall be deemed to materially and adversely
affect the interests of Certificateholders therein, and (subject to the applicable Mortgage Loan Seller’s right to cure such
Material Defect during the Initial Cure Period) such Mortgage Loan or Trust Subordinate Companion Loan shall be repurchased or
substituted for without regard to the Extended Cure Period described in the preceding sentence. If the affected Mortgage Loan or
Trust Subordinate Companion Loan is to be repurchased, the funds in the amount of the Purchase Price remitted by the applicable
Mortgage Loan Seller are to be remitted by wire transfer to the Master Servicer for deposit into the Collection Account.


 


If a Mortgage Loan Seller,
in connection with a Material Defect (or an allegation of a Material Defect) pertaining to a Mortgage Loan or Trust Subordinate
Companion Loan, makes a cash payment pursuant to an agreement or a settlement between the applicable Mortgage Loan Seller and the
Master Servicer or the Special Servicer, as applicable, on behalf of the Trust (and, for so long as no Control Termination Event
has occurred and is continuing and in respect of any Mortgage Loan that is not a Servicing Shift Mortgage Loan or an Excluded Loan
with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority
of the Controlling Class, the consent of the Directing Holder) (each such payment, a “Loss of Value Payment”)
with respect to such Mortgage Loan or Trust Subordinate Companion Loan, the amount of such Loss of Value Payment shall be deposited
into the Loss of Value Reserve Fund to be applied in accordance with Section 3.05(g) of this Agreement. The Loss of Value
Payment shall include the portion of any Liquidation Fees payable to the Special Servicer in respect of such Loss of Value Payment
and the portion of fees and reimbursable expenses of the Asset Representations Reviewer attributable to the Asset Review of such
Mortgage Loan. If such Loss of Value Payment is made, the Loss of Value Payment shall serve as the sole remedy available to the
Certificateholders and the Trustee on their behalf regarding any such Material Defect in lieu of any obligation of the Mortgage
Loan Seller to otherwise cure such Material Defect or repurchase or substitute for the affected Mortgage Loan or Trust Subordinate
Companion Loan based on such Material Defect under any circumstances. This paragraph is intended to apply only to a mutual agreement
or settlement between the applicable Mortgage Loan Seller and the Master Servicer (in the case of Non-Specially Serviced Loans)
or the Special Servicer (in the case of Specially Serviced Loans) on behalf of the Trust, provided that (i) prior to any
such agreement or settlement nothing in this paragraph shall preclude the Mortgage Loan Seller or the Master Servicer or the Special
Servicer, as applicable, from exercising any of its rights related to a Material Defect in the manner and timing set forth in the
related Mortgage Loan Purchase Agreement or this Section 2.03 (excluding this paragraph) (including any right to cure, repurchase
or substitute for such Mortgage Loan or Trust Subordinate Companion Loan), (ii) such Loss of Value Payment shall not be greater
than the Purchase Price of the affected Mortgage Loan or Trust Subordinate Companion Loan; and (iii) a Material Defect as a result
of a Mortgage Loan or Trust Subordinate Companion Loan not constituting a Qualified Mortgage may not be cured by a Loss of Value
Payment.


 



     -191-


     


    

 





With respect to any Non-Serviced
Mortgage Loan, if any “Material Defect” (or analogous term) exists under the related Non-Serviced PSA, and if the applicable
Mortgage Loan Seller (or other responsibly party) repurchases the Non-Serviced Companion Loan securitized thereunder from the trust
created pursuant to such Non-Serviced PSA, then the related Mortgage Loan Seller shall promptly repurchase such Non-Serviced Mortgage
Loan at the applicable Purchase Price; provided, however, that the foregoing shall not apply to any Defect related
solely to the promissory note for any related Non-Serviced Companion Loan.


 


If any Breach pertains
to a representation or warranty that the related Mortgage Loan documents or any particular Mortgage Loan document requires the
related Mortgagor to bear the costs and expenses associated with any particular action or matter under such Mortgage Loan document(s),
then the related Mortgage Loan Seller may cure such Breach within the applicable cure period (as the same may be extended) by reimbursing
the Trust (by wire transfer of immediately available funds) for (i) the reasonable amount of any such costs and expenses incurred
by the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee or the Trust that are incurred as a result
of such Breach and have not been reimbursed by the related Mortgagor and (ii) if such Mortgage Loan is or was a Delinquent Loan
subject to an Asset Review, the amount of any fees payable, without duplication, pursuant to Section 12.02(b) to the extent
not previously paid by the Mortgage Loan Seller to the Asset Representations Reviewer attributable to the Asset Review of such
Mortgage Loan; provided, however, that in the event any such costs and expenses exceed $10,000, the related Mortgage
Loan Seller shall have the option to either repurchase or substitute for the related Mortgage Loan as provided above or pay such
costs and expenses. Except as provided in the proviso to the immediately preceding sentence, the related Mortgage Loan Seller shall
remit the amount of such costs and expenses and upon its making such remittance, the related Mortgage Loan Seller shall be deemed
to have cured such Breach in all respects. To the extent any fees or expenses that are the subject of a cure by the related Mortgage
Loan Seller are subsequently obtained from the related Mortgagor, the portion of the cure payment made by the related Mortgage
Loan Seller equal to such fees or expenses obtained from the related Mortgagor shall promptly be returned to the related Mortgage
Loan Seller. Periodic Payments due with respect to each Qualified Substitute Mortgage Loan (if any) after the related Due Date
in the month of substitution, and Periodic Payments due with respect to each Mortgage Loan being repurchased or replaced after
the related Cut-off Date and received by the Master Servicer or the Special Servicer on behalf of the Trust on or prior to the
related date of repurchase or substitution, shall be part of the Trust Fund. Periodic Payments due with respect to each Qualified
Substitute Mortgage Loan (if any) on or prior to the related Due Date in the month of substitution, and Periodic Payments due with
respect to each Mortgage Loan being repurchased or replaced and received by the Master Servicer or the Special Servicer on behalf
of the Trust after the related date of repurchase or substitution, shall not be part of the Trust Fund and are to be remitted by
the Master Servicer or the Special Servicer to the applicable Mortgage Loan Seller effecting the related repurchase or substitution
promptly following receipt. Notwithstanding anything contained in this Agreement or the related Mortgage Loan Purchase Agreement,
no delay in either the discovery of a Material Defect or in providing notice of such Material Defect shall relieve the applicable
Mortgage Loan Seller of its obligation to cure, repurchase or substitute for (or make a Loss of Value Payment with respect to)
the related Mortgage Loan or Trust Subordinate Companion Loan if it is otherwise required to do so under the related Mortgage Loan
Purchase Agreement and/or this Article II unless (i) the related Mortgage Loan Seller did not otherwise discover or have


 






     -192-


     


    

 


knowledge of such Material Defect, (ii) such delay is a result of the failure by a party to the applicable Mortgage Loan Purchase
Agreement, or this Agreement (other than the Asset Representations Reviewer), to provide prompt notice as required by the terms
of the applicable Mortgage Loan Purchase Agreement, or this Agreement, after such party has actual knowledge of such Material Defect
(knowledge shall not be deemed to exist by reason of the Custodial Exception Report), (iii) such Material Defect does not relate
to the applicable Mortgage Loan (which, with respect to the Yorkshire & Lexington Towers Mortgage Loan and The Standard Highline
NYC Mortgage Loan, shall also include the related Trust Subordinate Companion Loan) not being a Qualified Mortgage and (iv) such
delay precludes such Mortgage Loan Seller from curing such Material Defect.


 


Pursuant to each Mortgage
Loan Purchase Agreement, if there is a Material Defect with respect to one or more Mortgaged Properties with respect to a Mortgage
Loan, the related Mortgage Loan Seller shall not be obligated to repurchase the Mortgage Loan if (i) the affected Mortgaged Property
may be released pursuant to the terms of any partial release provisions in the related Mortgage Loan documents (and such Mortgaged
Property is, in fact, released), (ii) the remaining Mortgaged Property(ies) satisfy the requirements, if any, set forth in the
Mortgage Loan documents and the related Mortgage Loan Seller provides an opinion of counsel to the effect that such release in
lieu of a repurchase would not (A) cause any Trust REMIC to fail to qualify as a REMIC or (B) result in the imposition of a tax
upon any Trust REMIC or the issuing entity and (iii) each applicable Rating Agency has provided a Rating Agency Confirmation.


 


(c)       Subject
to the applicable Mortgage Loan Seller’s right to cure as contemplated above in this Section 2.03, and further subject
to Section 2.01(b) and Section 2.01(c), any of the following shall cause a document in the Mortgage File to be deemed
to have a “Defect” that constitutes a Material Defect and to be conclusively presumed to materially and adversely affect
the interests of Certificateholders in a Mortgage Loan or a Trust Subordinate Companion Loan, as applicable, (but solely with respect
to clause (a)) and to be deemed to materially and adversely affect the interest of the Certificateholders in and the value
of a Mortgage Loan or Trust Subordinate Companion Loan, as applicable: (a) the absence from the Mortgage File of the original signed
Mortgage Note, unless the Mortgage File contains a signed lost note affidavit and indemnity with a copy of the Mortgage Note that
appears to be regular on its face; (b) the absence from the Mortgage File of the original signed Mortgage that appears to be regular
on its face, unless there is included in the Mortgage File either a copy of the Mortgage with evidence of recording thereon or
a copy of the Mortgage and a certificate from the related Mortgage Loan Seller stating that the original signed Mortgage was sent
for recordation (or certified by the applicable recorder’s office); (c) the absence from the Mortgage File of the item called
for by clause (viii) of the definition of Mortgage File; (d) the absence from the Mortgage File of any intervening assignments
required to create a complete chain of assignments to the Trustee on behalf of the Trust, unless there is included in the Mortgage
File either a copy of the assignment with evidence of recording thereon or a copy of the intervening assignment and a certificate
from the related Mortgage Loan Seller stating that the original intervening assignments were sent for filing or recordation (or
certified by the applicable recorder’s office), as applicable; (e) the absence from the Mortgage File of any required letter
of credit (except as permitted under Section 2.01(b)); or (f) with respect to any related leasehold Mortgage Loan, the absence
from the related Mortgage File of a copy (or an original, if


 






     -193-


     


    

 


available) of the related Ground Lease; provided, however,
that no Defect (except the Defects previously described in subclauses (a) through (f) of this Section 2.03(c))
shall be considered to materially and adversely affect the value of the related Mortgage Loan, the value of the related Mortgaged
Property or the interests of the Trustee or Certificateholders unless the document with respect to which the Defect exists is required
in connection with an imminent enforcement of the mortgagee’s rights or remedies under the related Mortgage Loan, defending
any claim asserted by any Mortgagor or third party with respect to the related Mortgage Loan or Trust Subordinate Companion Loan,
establishing the validity or priority of any lien on any collateral securing the related Mortgage Loan or Trust Subordinate Companion
Loan or for any immediate significant servicing obligation; provided, further, that no Defect relating to any Non-Serviced
Mortgage Loan previously described in subclauses (b) through (f) of this Section 2.03(c) shall be considered
to materially and adversely affect the value of such Mortgage Loan, the value of the related Mortgaged Property or the interests
of the Trustee or Certificateholders unless the related Mortgage Loan Seller, after receipt of notice of such Defect, is unable
to produce a copy of the document with respect to which the Defect exists within a reasonable period after receiving such notice
or otherwise establish that the original or copy, as applicable, of such document has been delivered, in compliance with the terms
of the related Non-Serviced PSA, to the custodian under the related Non-Serviced PSA. Notwithstanding the foregoing, the delivery
of executed escrow instructions or a binding commitment to issue a lender’s title insurance policy, as provided in clause
(viii) of the definition of Mortgage File herein, in lieu of the delivery of the actual policy of lender’s title insurance,
shall not be considered a Material Defect with respect to any Mortgage File if such actual policy is delivered to the Custodian
not later than eighteen (18) months following the Closing Date. Notwithstanding the foregoing, to the extent a Mortgage Loan Seller
has otherwise complied with its document delivery requirements under this Agreement and the related Mortgage Loan Purchase Agreement,
in the event that the Custodian has acknowledged receipt pursuant to Section 2.02 above of a document that is part of the
Mortgage File or a Mortgage Loan Seller can otherwise prove delivery of the document, and the Custodian subsequently loses a document,
the fact that such document is lost may not be utilized as the basis for a claim of a Material Defect against a Mortgage Loan Seller
pursuant to Section 6(e) of the related Mortgage Loan Purchase Agreement and/or this Section 2.03 and the Custodian shall
be liable for any such loss to the extent provided for in Section 8.01.


 


(d)       In
connection with any repurchase of, or substitution of a Qualified Substitute Mortgage Loan for, a Mortgage Loan or any repurchase
of a Trust Subordinate Companion Loan contemplated by this Section 2.03, the Trustee, the Certificate Administrator, the
Custodian, the Master Servicer and the Special Servicer shall each tender to the applicable Mortgage Loan Seller, upon delivery
to each of the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer of a trust receipt
executed by the applicable Mortgage Loan Seller evidencing such repurchase or substitution (other than with respect to any Trust
Subordinate Companion Loan in the case of a substitution), all portions of the Mortgage File and other documents pertaining to
such Mortgage Loan, Trust Subordinate Companion Loan possessed by each of the Trustee, the Certificate Administrator, the Custodian,
the Master Servicer and the Special Servicer (other than attorney-client communications that are privileged communications), and
each document that constitutes a part of the Mortgage File that was endorsed or assigned to the Trustee shall be endorsed or assigned,
as the case may be, to the applicable Mortgage Loan Seller in the same manner as provided in Section 6 of the related Mortgage
Loan Purchase Agreement and, if applicable, the definition of “Mortgage File” herein,


 






     -194-


     


    

 


so as to vest in such Mortgage
Loan Seller the legal and beneficial ownership of such repurchased or substituted Mortgage Loan or Trust Subordinate Companion
Loan (including property acquired in respect thereof and proceeds of any insurance policy with respect thereto) and the related
Mortgage Loan documents.


 


(e)       Section
6 of each of the Mortgage Loan Purchase Agreements provides the sole remedy available to the Certificateholders (subject to the
limitations on the rights of the Certificateholders under this Agreement), or the Trustee on behalf of the Certificateholders,
the Master Servicer or the Special Servicer, with respect to any Defect in a Mortgage File or any Breach of any representation
or warranty with respect to a Mortgage Loan or Trust Subordinate Companion Loan set forth in or required to be made pursuant to
Section 6 of any of the Mortgage Loan Purchase Agreements; provided that the foregoing shall in no way limit the ability
of the Master Servicer, Special Servicer or Trustee to take any action against BSPCC or BSPRTI, as applicable, to the extent provided
for pursuant to the related Mortgage Loan Purchase Agreement, including, without limitation, pursuant to Sections 20 and 21 thereof..


 


(f)        The
Master Servicer (in the case of Non-Specially Serviced Loans) or the Special Servicer (in the case of Specially Serviced Loans)
shall, for the benefit of the Certificateholders and the Trustee (as holder of the Lower-Tier Regular Interests), enforce the obligations
of the applicable Mortgage Loan Seller under the applicable Mortgage Loan Purchase Agreement. Such enforcement, including, without
limitation, the legal prosecution of claims, if any, shall be carried out in accordance with the Servicing Standard. Any costs
incurred by the Master Servicer or the Special Servicer with respect to the enforcement of the obligations of the applicable Mortgage
Loan Seller under the applicable Mortgage Loan Purchase Agreement shall, to the extent not recovered from the applicable Mortgage
Loan Seller, be deemed to be Servicing Advances to the extent not otherwise provided for herein. The Master Servicer or the Special
Servicer, as applicable, shall be reimbursed for the reasonable costs of such enforcement: first, from a specific recovery,
if any, of costs, expenses or attorneys’ fees against the applicable Mortgage Loan Seller; second, pursuant to Section
3.05(a)(vii) herein out of the related Purchase Price, to the extent that such expenses are a specific component thereof; and
third, if at the conclusion of such enforcement action it is determined that the amounts described in clauses first
and second are insufficient, then pursuant to Section 3.05(a)(viii) herein out of general collections on the Mortgage
Loans on deposit in the Collection Account. Any costs, expenses or attorneys’ fees related to a repurchase of a Companion
Loan shall be paid pursuant to the related Intercreditor Agreement or pursuant to the documents related to an Other Securitization,
if applicable.


 


(g)       If
a Mortgage Loan Seller incurs any expense in connection with the curing of a Breach, which also constitutes a default under the
related Mortgage Loan or Trust Subordinate Companion Loan, as applicable, and is reimbursable thereunder, such Mortgage Loan Seller
shall have a right, and shall be subrogated to the rights of the Trustee and the Trust under the Mortgage Loan to recover the amount
of such expenses from the related Mortgagor; provided, however, that such Mortgage Loan Seller’s rights pursuant
to this Section 2.03(g) shall be junior, subject and subordinate to the rights of the Trustee, the Certificate Administrator,
the Trust, the Master Servicer and the Special Servicer to recover amounts owed by the related Mortgagor under the terms of such
Mortgage Loan including, without limitation, the rights to recover unreimbursed Advances, accrued and unpaid interest on Advances
at the Reimbursement


 






     -195-


     


    

 


Rate, fees owed to the Special Servicer, and unpaid or unreimbursed expenses of the Trustee, the Certificate
Administrator, the Trust, the Master Servicer or the Special Servicer allocable to such Mortgage Loan. The Master Servicer or,
with respect to a Specially Serviced Loan, the Special Servicer, shall use reasonable efforts to recover such expenses for such
Mortgage Loan Seller to the extent consistent with the Servicing Standard, but taking into account the subordinate nature of the
reimbursement to the related Mortgage Loan Seller; provided, however, that the Master Servicer or, with respect to
a Specially Serviced Loan, the Special Servicer, determines in the exercise of its sole discretion consistent with the Servicing
Standard that such actions by it will not impair the Master Servicer’s and/or the Special Servicer’s collection or
recovery of principal, interest and other sums due with respect to the related Mortgage Loan that would otherwise be payable to
the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator and the Certificateholders pursuant to the
terms of this Agreement; provided, further, that the Master Servicer or, with respect to a Specially Serviced Loan,
the Special Servicer, may waive the collection of amounts due on behalf of such Mortgage Loan Seller in its sole discretion in
accordance with the Servicing Standard.


 


(h)       If
(i) any Crossed Underlying Loan is required to be repurchased or substituted for in the manner described in this Section 2.03
and (ii) the applicable Material Defect does not constitute a Material Defect as to any other Crossed Underlying Loan in the related
Crossed Mortgage Loan Group (without regard to this paragraph), then the applicable Material Defect shall be deemed to constitute
a Material Defect as to any other Crossed Underlying Loan in the related Crossed Mortgage Loan Group for purposes of this paragraph,
and the related Mortgage Loan Seller shall repurchase or substitute for such other Crossed Underlying Loan(s) in the related Crossed
Mortgage Loan Group as provided in Section 2.03(b) unless such other Crossed Underlying Loans satisfy the Crossed Underlying
Loan Repurchase Criteria. In the event that the remaining Crossed Underlying Loans in such Crossed Mortgage Loan Group satisfy
the Crossed Underlying Loan Repurchase Criteria, the applicable Mortgage Loan Seller may elect either to repurchase or substitute
for only the affected Crossed Underlying Loan(s) as to which the related Material Defect exists or to repurchase or substitute
for all of the Crossed Underlying Loans in the related Crossed Mortgage Loan Group. Any reserve or other cash collateral or letters
of credit securing the Crossed Underlying Loans shall be allocated among the related Crossed Underlying Loans in accordance with
the related Mortgage Loan documents or otherwise on a pro rata basis based upon their outstanding Stated Principal Balances.
Except as provided in this Section 2.03(h) and Section 2.03(i), all other terms of the related Mortgage Loans shall
remain in full force and effect without any modification thereof.


 


(i)        Notwithstanding
the foregoing, if the related Mortgage provides for the partial release of one or more of the Crossed Underlying Loans, the Depositor
may cause the related Mortgage Loan Seller to repurchase only that Crossed Underlying Loan required to be repurchased pursuant
to this Section 2.03, pursuant to the partial release provisions of the related Mortgage; provided, however,
that (i) the remaining related Crossed Underlying Loan(s) fully comply with the terms and conditions of the related Mortgage, this
Agreement and the related Mortgage Loan Purchase Agreement, including the Crossed Underlying Loan Repurchase Criteria, (ii) in
connection with such partial release, the related Mortgage Loan Seller obtains an Opinion of Counsel (at such Mortgage Loan Seller’s
expense) to the effect that the contemplated action will not cause an Adverse REMIC Event and (iii) in connection with such partial

the related Mortgage Loan Seller delivers or causes to be delivered to the Custodian original modifications to the Mortgage
prepared and executed in connection with such partial release.


 


(j)        With
respect to any Crossed Underlying Loan, to the extent that the applicable Mortgage Loan Seller is required to repurchase or substitute
for such Crossed Underlying Loan in the manner prescribed in Section 2.03(h) or Section 2.03(i) while the Trustee
continues to hold any other Crossed Underlying Loans in the related Crossed Mortgage Loan Group, the applicable Mortgage Loan Seller
and the applicable Master Servicer or, with respect to a Specially Serviced Loan, the Special Servicer, on behalf of the Trustee,
as assignee of the Depositor, will, as set forth in the related Mortgage Loan Purchase Agreement, forbear from enforcing any remedies
against the other’s Primary Collateral but each will be permitted to exercise remedies against the Primary Collateral securing
its respective related Mortgage Loans, including with respect to the Trustee, the Primary Collateral securing the Mortgage Loans
still held by the Trustee, so long as such exercise does not materially impair the ability of the other party to exercise its remedies
against its Primary Collateral. If the exercise of the remedies by one party would materially impair the ability of the other party
to exercise its remedies with respect to the Primary Collateral securing the Crossed Underlying Loans held by such party, then
both parties have agreed in the related Mortgage Loan Purchase Agreement to forbear from exercising such remedies until the Mortgage
Loan documents evidencing and securing the relevant Mortgage Loan can be modified in a manner that complies with the related Mortgage
Loan Purchase Agreement to remove the threat of material impairment as a result of the exercise of remedies.


 


(k)       (i)
In the event an Initial Requesting Certificateholder delivers a written request to a party to this Agreement that a Mortgage Loan
or Trust Subordinate Companion Loan be repurchased by the applicable Mortgage Loan Seller alleging the existence of a Material
Defect with respect to such Mortgage Loan or Trust Subordinate Companion Loan and setting forth the basis for such allegation (a
“Certificateholder Repurchase Request”), such party shall promptly forward that Certificateholder Repurchase
Request to the related Mortgage Loan Seller and each other party to this Agreement. Subject to Section 2.03(l), the Master
Servicer (in the case of Non-Specially Serviced Loans) and the Special Servicer (in the case of Specially Serviced Loans) (the
“Enforcing Servicer”) shall be the Enforcing Party with respect to a Certificateholder Repurchase Request.


 


(ii)         In
the event that the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator or the Operating
Advisor (solely in its capacity as Operating Advisor) obtains knowledge of a Material Defect with respect to a Mortgage Loan or
Trust Subordinate Companion Loan, that party shall deliver prompt written notice of such Material Defect to each other party to
this Agreement identifying the applicable Mortgage Loan or Trust Subordinate Companion Loan and setting forth the basis for such
allegation (an “PSA Party Repurchase Request” and, either a Certificateholder Repurchase Request or a PSA Party
Repurchase Request, the “Repurchase Request”) and the Master Servicer (with respect to Non-Specially Serviced
Loans) or the Special Servicer (with respect to Specially Serviced Loans) will be required to promptly send the PSA Party Repurchase
Request to the related Mortgage Loan Seller. Prior to the occurrence of a Resolution Failure, the Master Servicer (with respect
to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) shall act as the Enforcing


 






     -197-


     


    

 


Party and enforce the rights of the Trust against the related Mortgage Loan Seller with respect to a PSA Party Repurchase Request.


 


(iii)        In
the event the Repurchase Request is not Resolved within 180 days after the Mortgage Loan Seller receives the Repurchase Request
(a “Resolution Failure”), then the provisions described in Section 2.03(l) below shall apply. Receipt
of the Repurchase Request shall be deemed to occur two (2) Business Days after the Repurchase Request is sent to the related Mortgage
Loan Seller.


 


After the Dispute Resolution
Cut-off Date, if no Certificateholder or Certificate Owner has become a Requesting Certificateholder, no Certificateholder or Certificate
Owner shall have the right to elect to refer the Repurchase Request to mediation or arbitration and the Enforcing Servicer, as
the Enforcing Party, shall be the sole party entitled to enforce the Trust’s rights against the related Mortgage Loan Seller,
subject to the consent or consultation rights of the Directing Holder pursuant to Section 6.08.


 


(l)        (i)
After a Resolution Failure occurs with respect to a Repurchase Request regarding a Mortgage Loan or Trust Subordinate Companion
Loan (whether the Repurchase Request was initiated by an Initial Requesting Certificateholder or by a party to this Agreement),
the Enforcing Servicer will be required to send a notice (a “Proposed Course of Action Notice”) to the Initial
Requesting Certificateholder, if any, to the address specified in the Initial Requesting Certificateholder’s Repurchase Request,
and to the Certificate Administrator (which shall be delivered via electronic mail to trustadministrationgroup@wellsfargo.com)
who shall make such notice available to all other Certificateholders and Certificate Owners (by posting such notice on the Certificate
Administrator’s Website) indicating the Enforcing Servicer’s intended course of action with respect to the Repurchase
Request (a “Proposed Course of Action”). Such notice shall include (a) a request to Certificateholders to indicate
their agreement with or dissent from such Proposed Course of Action by clearly marking “agree” or “disagree”
to the Proposed Course of Action on such notice within 30 days of the date of such notice and a disclaimer that responses received
after such 30-day period shall not be taken into consideration, (b) a statement that in the event any Certificateholder disagrees
with the Proposed Course of Action, the Enforcing Servicer shall be compelled to follow or accept the course of action agreed to
and/or proposed by the majority of the responding Certificateholders that involves referring the matter to mediation or arbitration,
as the case may be, (c) a statement that responding Certificateholders will be required to certify their holdings in connection
with such response, (d) a statement that only responses clearly marked “agree” or “disagree” with such
Proposed Course of Action will be taken into consideration and (e) instructions for responding Certificateholders to send their
responses to the applicable Enforcing Servicer and the Certificate Administrator. If (a) the Enforcing Servicer’s intended
course of action with respect to the Repurchase Request does not involve pursuing further action to exercise rights against the
applicable Mortgage Loan Seller with respect to the Repurchase Request but the Initial Requesting Certificateholder, if any, or
any other Certificateholder or Certificate Owner wishes to exercise its right to refer the matter to mediation (including nonbinding
arbitration) or arbitration, or (b) the Enforcing Servicer’s intended course of action is to pursue further action to exercise
rights against the applicable Mortgage Loan Seller with respect to the Repurchase Request but the Initial Requesting Certificateholder,
if any, or any other Certificateholder or Certificate Owner does not agree with the dispute resolution method selected by the Enforcing
Servicer, then the Initial Requesting


 






     -198-


     


    

 


Certificateholder, if any, or such other Certificateholder or Certificate Owner may deliver
to the Enforcing Servicer a written notice (a “Preliminary Dispute Resolution Election Notice”) within 30 days
from the date the Proposed Course of Action Notice is posted on the Certificate Administrator’s Website (the “Dispute
Resolution Cut-off Date”) indicating its intent to exercise its right to refer the matter to either mediation or arbitration.
In the event any Certificateholder or Certificate Owner delivers a Preliminary Dispute Resolution Election Notice, and the Enforcing
Servicer has also received responses from other Certificateholders or Certificate Owners supporting the Enforcing Servicer’s
initial Proposed Course of Action, such responses shall be considered Preliminary Dispute Resolution Election Notices supporting
the Proposed Course of Action. The Certificate Administrator shall within three (3) Business Days after the expiration of the 30-day
response period, tabulate the responses received from the Certificateholders and share the results with the Enforcing Servicer.
The Certificate Administrator shall only count responses timely received and clearly indicating agreement or dissent with the related
Proposed Course of Action and additional verbiage or qualifying language shall not be taken into consideration for purposes of
determining whether the related Certificateholder agrees or disagrees with the Proposed Course of Action. The Certificate Administrator
shall be under no obligation to answer any questions from Certificateholders regarding such Proposed Course of Action. For the
avoidance of doubt, the Certificate Administrator’s obligations in connection with this Section 2.03(l) shall be limited
solely to tabulating Certificateholder responses of “agree” or “disagree” to the Proposed Course of Action,
and such obligation shall not be construed to impose any enforcement obligation on the Certificate Administrator. The Enforcing
Servicer may conclusively rely (without investigation) on the Certificate Administrator’s tabulation of the majority of the
responding Certificateholders.


 


(ii)         If
neither the Initial Requesting Certificateholder, if any, nor any other Certificateholder or Certificate Owner delivers a Preliminary
Dispute Resolution Election Notice prior to the Dispute Resolution Cut-off Date, no Certificateholder or Certificate Owner shall
have the right to refer the Repurchase Request to mediation or arbitration, and the Enforcing Servicer shall be the sole party
entitled to enforce the Trust’s rights against the related Mortgage Loan Seller, subject to the consent or consultation rights
of the Directing Holder pursuant to Section 6.08.


 


(iii)        Promptly
and in any event within 10 Business Days following receipt of a Preliminary Dispute Resolution Election Notice from (a) the Initial
Requesting Certificateholder, if any, or (b) any other Certificateholder or Certificate Owner (each of clauses (a) and (b),
a “Requesting Certificateholder”), the Enforcing Servicer will be required to consult with each Requesting Certificateholder
regarding such Requesting Certificateholder’s intention to elect either mediation (including nonbinding arbitration) or arbitration
as the dispute resolution method with respect to the Repurchase Request (the “Dispute Resolution Consultation”)
so that such Requesting Certificateholder may consider the views of the Enforcing Servicer as to the claims underlying the Repurchase
Request and possible dispute resolution methods, such discussions to occur and be completed no later than 10 Business Days following
the Dispute Resolution Cut-off Date. The Enforcing Servicer shall be entitled to establish procedures the Enforcing Servicer deems
in good faith to be in accordance with the Servicing Standard relating to the timing and extent of such consultations. No later
than 5 Business Days after completion of the Dispute Resolution Consultation, a Requesting Certificateholder may provide a final


 






     -199-


     


    

 


notice to the Enforcing Servicer indicating its decision to exercise its right to refer the matter to either mediation or arbitration
(“Final Dispute Resolution Election Notice”).


 


(iv)        If,
following the Dispute Resolution Consultation, no Requesting Certificateholder timely delivers a Final Dispute Resolution Election
Notice to the Enforcing Servicer, then the Enforcing Servicer will continue to act as the Enforcing Party and will remain obligated
under this Agreement to enforce the rights of the Trust with respect to the Repurchase Request and no Certificateholder or Certificate
Owner shall have any further right to elect to refer the matter to mediation or arbitration.


 


(v)    
   If a Requesting Certificateholder timely delivers a Final Dispute Resolution Election Notice to the
Enforcing Servicer, then such Requesting Certificateholder shall become the Enforcing Party and must promptly submit the
matter to mediation (including nonbinding arbitration) or arbitration. If there are more than one Requesting
Certificateholder that timely deliver a Final Dispute Resolution Election Notice, then such Requesting Certificateholders
will collectively become the Enforcing Party, and the holder or holders of a majority of the Voting Rights among such
Requesting Certificateholders will be entitled to make all decisions relating to such mediation or arbitration. If, however,
no Requesting Certificateholder commences arbitration or mediation pursuant to the terms of this Agreement within 30 days
after delivery of its Final Dispute Resolution Election Notice to the Enforcing Servicer, then (i) the rights of a Requesting
Certificateholder to act as the Enforcing Party shall terminate and no Certificateholder or Certificate Owner shall have any
further right to elect to refer the matter to mediation or arbitration, (ii) if the Proposed Course of Action Notice
indicated that the Enforcing Servicer shall take no further action with respect to the Repurchase Request, then the related
Material Defect shall be deemed waived for all purposes under this Agreement and the related Mortgage Loan
Purchase Agreement, and (iii) if the Proposed Course of Action Notice had indicated a course of action other than the course
of action under clause (ii), then the Enforcing Servicer shall again become the Enforcing Party and, as such, shall be the
sole party entitled to enforce the Trust’s rights against the related Mortgage Loan Seller.


 


(vi)        Notwithstanding
the foregoing, the dispute resolution provisions described above under this Section 2.03(l) shall not apply, and the Enforcing
Servicer shall remain the Enforcing Party, if the Enforcing Servicer has commenced litigation with respect to the Repurchase Request,
or determines in accordance with the Servicing Standard that it is in the best interest of Certificateholders to commence litigation
with respect to the Repurchase Request to avoid the running of any applicable statute of limitations.


 


(vii)       In
the event a Requesting Certificateholder becomes the Enforcing Party, the Enforcing Servicer, on behalf of the Trust, shall remain
a party to any proceedings against the related Mortgage Loan Seller.


 


(viii)      For
the avoidance of doubt, none of the Depositor, any Mortgage Loan Seller nor any of their respective Affiliates shall be entitled
to be an Initial Requesting Certificateholder or a Requesting Certificateholder.


 



     -200-


     


    

 





(ix)        The
Requesting Certificateholder is entitled to elect either mediation or arbitration in its sole discretion; however, the Requesting
Certificateholder shall not be entitled to then utilize the alternative method in the event that the initial method is unsuccessful.


 


(m)      If
the Enforcing Party selects mediation (including nonbinding arbitration), the following provisions shall apply:


 


(i)          The
mediation shall be administered by a nationally recognized mediation services provider selected by the related Mortgage Loan Seller
(such provider, the “Mediation Services Provider”) in accordance with published mediation procedures (the “Mediation
Rules”) promulgated by the Mediation Services Provider.


 


(ii)         The
mediator shall be impartial, an attorney and have at least fifteen (15) years of experience in commercial litigation and either
commercial real estate finance or commercial mortgage-backed securitization matters or other complex commercial transactions and
who will be appointed from a list of neutrals maintained by the Mediation Services Provider. Upon being supplied a list of at least
ten potential mediators by the Mediation Services Provider each party will have the right to exercise two peremptory challenges
within fourteen (14) days and to rank the remaining potential mediators in order of preference. The Mediation Services Provider
shall select the mediator from the remaining attorneys on the list respecting the preference choices of the parties to the extent
possible.


 


(iii)        The
parties shall use commercially reasonable efforts to conduct an organizational conference to begin the mediation within 10 Business
Days of the selection of the mediator and to conclude the mediation within 60 days thereafter.


 


(iv)        The
expenses of any mediation will be allocated among the parties to the mediation, including, if applicable, between the Enforcing
Party and Enforcing Servicer, as mutually agreed by the parties as part of the mediation.


 


(n)       If
the Enforcing Party selects third-party arbitration, the following provisions will apply:


 


(i)          The
arbitration shall be administered by a nationally recognized arbitration services provider selected by the related Mortgage Loan
Seller (such provider, the “Arbitration Services Provider”) in accordance with published arbitration procedures
(the “Arbitration Rules”) promulgated by the Arbitration Services Provider.


 


(ii)         The
arbitrator shall be impartial, an attorney and have at least fifteen (15) years of experience in commercial litigation and either
commercial real estate finance or commercial mortgage-backed securitization matters or other complex commercial transactions and
who will be appointed from a list of neutrals maintained by the Arbitration Services Provider. Upon being supplied a list of at
least ten potential arbitrators by the Arbitration Services Provider each party will have the right to exercise two peremptory
challenges within fourteen (14) days and to rank the remaining potential arbitrators in order of preference. The Arbitration Services
Provider will select the


 






     -201-


     


    

 


arbitrator from the remaining attorneys on the list respecting the preference choices of the parties to
the extent possible.


 


(iii)        Prior
to accepting an appointment, the arbitrator must promptly disclose any circumstances likely to create a reasonable inference of
bias or conflict of interest or likely to preclude completion of the hearings within the prescribed time schedule.


 


(iv)        After
consulting with the parties at an organizational conference held not later than 10 Business Days after its appointment, the arbitrator
shall devise procedures and deadlines for the arbitration, to the extent not already agreed to by the parties, with the goal of
expediting the proceeding and completing the arbitration within 120 days. The arbitrator shall have the authority to schedule,
hear, and determine any and all motions, including dispositive and discovery motions, in accordance with the Federal Rules of Civil
Procedure for non-jury matters (the “Rules”) (including summary judgment and other prehearing and post hearing
motions), and will do so by reasoned decision on the motion of any party to the arbitration.


 


(v)    
    Notwithstanding whatever other discovery may be available under the Rules, unless otherwise agreed by
the parties, each party to the arbitration will be presumptively limited to the following discovery in the arbitration: (A)
the parties shall reasonably and in good faith voluntarily produce to all other parties all documents upon which they intend
to rely and all documents they reasonably and in good faith believe to be relevant to the claims or defenses asserted by any
of the parties, (B) party witness depositions (excluding Rule 30b-6 witnesses), and (C) expert witness depositions, provided
that the arbitrator shall have the ability to grant the parties, or either of them, additional discovery to the extent that
the arbitrator determines good cause is shown that such additional discovery is reasonable and necessary.


 


(vi)        The
arbitrator shall make its final determination no later than 30 days after the conclusion of the hearings and submission of any
post-hearing submissions. The arbitrator shall resolve the dispute in accordance with the terms of the related Mortgage Loan Purchase
Agreement and this Agreement, and may not modify or change those agreements in any way or award remedies not consistent with those
agreements. The arbitrator will not have the power to award punitive damages or consequential damages in any arbitration conducted
by them. Interest on any monetary award shall bear interest from the date of the Final Dispute Resolution Election Notice at the
Prime Rate. In its final determination, the arbitrator shall determine and award the costs of the arbitration (including the fees
of the arbitrator, cost of any record or transcript of the arbitration, and administrative fees) and shall award reasonable attorneys’
fees to the parties to the arbitration as determined by the arbitrator in its reasonable discretion. The determination of the arbitrator
shall be by a reasoned decision in writing and counterpart copies will be promptly delivered to the parties. The final determination
of the arbitrator shall be final and non-appealable, except for actions to confirm or vacate the determination permitted under
federal or state law, and may be enforced in any court of competent jurisdiction.


 


(vii)     
By selecting arbitration, the selecting party is giving up the right to sue in court, including the right to a trial by
jury.


 



     -202-


     


    

 





(viii)      No
person may bring a putative or certificated class action to arbitration.


 


(o)       The
following provisions will apply to both mediation and third-party arbitration:


 


(i)          Any
mediation or arbitration will be held in New York, New York unless another location is agreed by all parties;


 


(ii)         If
the dispute involves a matter that cannot effectively be remedied by the payment of damages, or if there be any dispute relating
to arbitration or the arbitrators that cannot be resolved promptly by the arbitrators or the Arbitration Services Provider, then
any party in such instance may during the pendency of the arbitration proceedings seek temporary equitable remedies, pending the
final decision of the arbitration panel, solely by application in the Southern District of New York if such court shall have subject
matter jurisdiction, or if the Southern District of New York has no jurisdiction, then in the Supreme Court of the State of New
York for the County of New York. The arbitration proceedings shall not be stayed unless so ordered by the court.


 


(iii)  
    The details and/or existence of any Repurchase Request, any informal meetings, mediations or
arbitration proceedings conducted under this Section 2.03, including all offers, promises, conduct and statements,
whether oral or written, made in the course of the parties’ attempt to informally resolve any Repurchase Request, will
be confidential, privileged and inadmissible for any purpose, including impeachment, in any mediation, arbitration or
litigation, or other proceeding (including any proceeding under this Section 2.03). Such information will be kept
strictly confidential and shall not be disclosed or shared with any third party (other than a party’s attorneys,
experts, accountants and other agents and representatives, as reasonably required in connection with any resolution procedure
under this Section 2.03), except as otherwise required by law, regulatory requirement or court order. If any party to
a resolution procedure receives a subpoena or other request for information from a third party (other than a governmental
regulatory body) for such confidential information, the recipient shall promptly notify the other party to the resolution
procedure and shall provide the other party with a reasonable opportunity to object to the production of its confidential
information.


 


(iv)        In
the event a Requesting Certificateholder is the Enforcing Party, the agreement with the arbitrator or mediator, as the case may
be, shall be required to contain an acknowledgment that the Trust, or the Enforcing Servicer on its behalf, shall be a party to
any arbitration or mediation proceedings solely for the purpose of being the beneficiary of any award in favor of the Enforcing
Party; provided that the degree and extent to which the Enforcing Servicer actively prepares for and participates in such
proceeding shall be determined by such Enforcing Servicer in consultation with the Directing Holder (provided that no Consultation
Termination Event has occurred and is continuing and an Excluded Loan is not involved), and in accordance with the Servicing Standard.
All amounts recovered by the Enforcing Party shall be paid to the Trust, or the Enforcing Servicer on its behalf, and deposited
in the Collection Account. The agreement with the arbitrator or mediator, as the case may be, shall provide that in the event a
Requesting Certificateholder is allocated any related costs and expenses pursuant to the terms of the


 






     -203-


     


    

 


arbitrator’s decision
or the agreement reached in mediation, neither the Trust nor the Enforcing Servicer acting on its behalf shall be responsible for
any such costs and expenses allocated to the Requesting Certificateholder.


 


(v)         In
the event a Requesting Certificateholder is the Enforcing Party, the Requesting Certificateholder is required to pay any expenses
allocated to the Enforcing Party in the arbitration proceedings or any expenses that the Enforcing Party agrees to bear in the
mediation proceedings.


 


(vi)        The
Trust (or the Enforcing Servicer or the Trustee, acting on its behalf), the Depositor or any Mortgage Loan Seller shall be permitted
to redact any personally identifiable customer information included in any information provided for purposes of any mediation or
arbitration. Each party to the proceedings shall be required to agree to keep confidential the details related to the Repurchase
Request and the dispute resolution identified in connection with such procedures; provided, however, that the Certificateholders
shall be permitted to communicate prior to the commencement of any such proceedings to the extent provided in Section 5.06.


 


(vii)       For
the avoidance of doubt, in no event shall the exercise of any right of a Requesting Certificateholder to refer a Repurchase Request
to mediation or arbitration affect in any manner the ability of the Enforcing Servicer to perform its obligations with respect
to a Mortgage Loan or the exercise of any rights of a Directing Certificateholder.


 


(viii)      In
the event that the method of dispute resolution selected is unsuccessful, the Requesting Certificateholder may not elect to then
utilize the alternative method.


 


(ix)        Any
out-of-pocket expenses required to be borne by the Enforcing Servicer in a mediation or arbitration shall be reimbursable as trust
fund expenses.

that in no event shall the Master Servicer or the Special Servicer, as the case may be, take any action or omit to take any

or Serviced Whole Loans or (B) in the case of a Specially Serviced Loan or an REO Property, maximization of timely recovery of
principal and interest on a net present value basis on such Mortgage Loans and any related Serviced Companion Loans, and the best
interests of the Trust and the Certificateholders (as a collective whole as if such Certificateholders constituted a single lender)
(and in the case of any Whole Loan, the best interests of the Trust, the Certificateholders and any related Companion Holder (as
a collective whole as if such Certificateholders and the holder or holders of the related Companion Loan constituted a single
lender), taking into account the subordinate or pari passu

nature of the related Companion Loan), as determined
by the Master Servicer or the Special Servicer, as the case may be, in its reasonable judgment, in either case giving due consideration
to the customary and usual standards of practice of prudent institutional commercial, multifamily and manufactured housing community
mortgage loan servicers, but without regard to any conflict of interest arising from: (i) any relationship that the Master Servicer,
the Special Servicer or any Affiliate of the Master Servicer or the Special Servicer may have with any Mortgagor or any Affiliate
of such Mortgagor, any Mortgage Loan Seller, any other parties to this Agreement, any Sponsor, any originator of a Mortgage Loan
or any Affiliate of any of the foregoing; (ii) the ownership of any Certificate, Companion Loan, mezzanine loan, or subordinate
debt relating to a Mortgage Loan by the Master Servicer, the Special Servicer or any Affiliate of the Master Servicer or the Special
Servicer, as applicable; (iii) the obligation, if any, of the Master Servicer to make Advances; (iv) the right of the Master Servicer
or the Special Servicer, as the case may be, or any of its Affiliates to receive compensation for its services and reimbursement
for its costs hereunder or with respect to any particular transaction; (v) the ownership, servicing or management for others of
(a) the Non-Serviced Mortgage Loans and the Non-Serviced Companion Loans or (b) any other mortgage loans, subordinate debt, mezzanine
loans or properties not covered by this Agreement or held by the Trust by the Master Servicer or the Special Servicer, as the case
may be, or any of its Affiliates; (vi) any debt that the Master Servicer or the Special Servicer, as the case may be, or any of
its Affiliates, has extended to any Mortgagor or an Affiliate of any Mortgagor (including, without limitation, any mezzanine financing);
(vii) any option to purchase any Mortgage Loan or the related Companion Loan the Master Servicer or the Special Servicer, as the
case may be, or any of its Affiliates, may have; and (viii) any obligation of the Master Servicer or the Special Servicer, or any
of their respective Affiliates, to repurchase, substitute for or make a Loss of Value Payment with respect to a Mortgage Loan or
Trust Subordinate Companion Loan as a Mortgage Loan Seller (if the Master Servicer or the Special Servicer or any of their respective
Affiliates is a Mortgage Loan Seller) (the foregoing, collectively referred to as the “Servicing Standard”).


 


The Master Servicer and
the Special Servicer shall act in accordance with the Servicing Standard with respect to any action required to be taken regarding
the Non-Serviced Mortgage Loans pursuant to their obligations under this Agreement.


 


Without limiting the
foregoing, subject to Section 3.19, the Special Servicer shall be obligated to service and administer (i) any Mortgage Loans
(other than the Non-Serviced Mortgage Loans, except in the case of Section 2.03(f) and Section 2.03(k) through Section
2.03(o)), any related Serviced Companion Loans as to which a Servicing Transfer Event has occurred and is continuing (each,
a “Specially Serviced Loan”) or as otherwise provided herein with respect to Non-Specially Serviced Loans in
connection with any Major Decision and (ii) any REO Properties (other than the Non-Serviced Mortgaged Properties); provided
that the Master Servicer shall continue to receive payments and make all calculations, and prepare, or cause to be prepared, all
reports, required hereunder with respect to the Specially Serviced Loans, except for the reports specified herein as prepared by
the Special Servicer, as if no Servicing Transfer Event had occurred and with respect to the REO Properties (and the related REO
Loans) as if no REO Acquisition had occurred, and to render such services with respect to such Specially Serviced Loans and REO
Properties as are specifically provided for herein; provided, further, however, that the Master Servicer shall
not be liable for failure to comply with such duties insofar as such failure results from a failure of the Special Servicer to
provide


 






     -207-


     


    

 


sufficient information to the Master Servicer to comply with such duties or failure by the Special Servicer to otherwise
comply with its obligations hereunder. The Master Servicer, in its capacity as Master Servicer, will not have any responsibility
for the performance by the Special Servicer, in its capacity as Special Servicer, of its duties under this Agreement. The Special
Servicer, in its capacity as Special Servicer, will not have any responsibility for the performance by the Master Servicer, in
its capacity as Master Servicer, of its duties under this Agreement. Each Mortgage Loan or any related Serviced Companion Loan
that becomes a Specially Serviced Loan shall continue as such until satisfaction of the conditions specified in Section 3.19(a).
Without limiting the foregoing, subject to Section 3.19, the Master Servicer shall be obligated to service and administer
any Non-Specially Serviced Loan or any related Serviced Companion Loan. The Special Servicer shall make the property inspections,
use its reasonable efforts to collect the financial statements, budgets, operating statements and rent rolls and forward to the
Master Servicer the reports in respect of the related Mortgaged Properties with respect to Specially Serviced Loans in accordance
with Section 3.12. After notification to the Master Servicer, the Special Servicer may contact the Mortgagor of any Non-Specially
Serviced Loan if efforts by the Master Servicer to collect required financial information have been unsuccessful or any other issues
remain unresolved. Such contact shall be coordinated through and with the cooperation of the Master Servicer. No provision herein
contained shall be construed as an express or implied guarantee by the Master Servicer or the Special Servicer of the collectability
or recoverability of payments on the Mortgage Loans or any related Serviced Companion Loan or shall be construed to impair or adversely
affect any rights or benefits provided by this Agreement to the Master Servicer or the Special Servicer (including with respect
to Servicing Fees, Special Servicing Fees or the right to be reimbursed for Advances and interest accrued thereon). Any provision
in this Agreement for any Advance by the Master Servicer or the Trustee is intended solely to provide liquidity for the benefit
of the Certificateholders and not as credit support or otherwise to impose on any such Person the risk of loss with respect to
one or more of the Mortgage Loans or any related Serviced Companion Loans. No provision hereof shall be construed to impose liability
on the Master Servicer or the Special Servicer for the reason that any recovery to the Certificateholders in respect of a Mortgage
Loan at any time after a determination of present value recovery is less than the amount reflected in such determination.


 


(b)       Subject
only to the Servicing Standard and the terms of this Agreement (including, without limitation, Section 6.08) and of the
respective Mortgage Loans or any related Serviced Companion Loans and any related Intercreditor Agreement, if applicable, and applicable
law, the Master Servicer and the Special Servicer each shall have full power and authority, acting alone or, in the case of the
Master Servicer, subject to Section 3.20, through one or more Sub-Servicers, to do or cause to be done any and all things
in connection with such servicing and administration for which it is responsible which it may deem necessary or desirable. Without
limiting the generality of the foregoing, each of the Master Servicer and the Special Servicer, in its own name (or in the name
of the Trustee and, if applicable, the related Serviced Companion Noteholder), is hereby authorized and empowered by the Trustee
to execute and deliver, on behalf of the Certificateholders (and, with respect to a Serviced Companion Loan, the related Serviced
Companion Noteholder) and the Trustee or any of them, with respect to each Mortgage Loan, any related Serviced Companion Loan,
it is obligated to service under this Agreement: (i) any and all financing statements, continuation statements and other documents
or instruments necessary to maintain the lien created by the related Mortgage or other security document in the related Mortgage
File on the related Mortgaged Property and


 






     -208-


     


    

 


related collateral, and shall, from time to time, execute and/or deliver such financing
statements, continuation statements and other documents or instruments as necessary to maintain the lien created by the related
Mortgage or other security document in the related Mortgage File on the related Mortgaged Property and related collateral; (ii)
subject to Sections 3.08, 3.18 and 6.08, any and all modifications, waivers, amendments or consents to, under
or with respect to any documents contained in the related Mortgage File; (iii) any and all instruments of satisfaction or cancellation,
pledge agreements and other documents in connection with a defeasance, or of partial or full release or discharge, and all other
comparable instruments; and (iv) any or all complaints or other pleadings to initiate and/or to terminate any action, suit or proceeding
on behalf of the Trust (in their representative capacities (except as set forth below in this paragraph). The Master Servicer (with
respect to Non-Specially Serviced Loans) and the Special Servicer (with respect to Specially Serviced Loans) shall provide to the
Mortgagor related to such Mortgage Loans or Trust Subordinate Companion Loans that it is servicing any reports required to be provided
to them pursuant to the related Mortgage Loan documents. Subject to Section 3.10, the Trustee shall (i) on the Closing Date,
furnish to the Master Servicer and the Special Servicer original powers of attorney in the form of Exhibit R-1 or R-2,
respectively, attached hereto (or such other form as mutually agreed to by the Trustee and the Master Servicer or the Special Servicer,
as applicable) and (ii) upon request, furnish, or cause to be furnished, to the Master Servicer or the Special Servicer any powers
of attorney substantially in the form of Exhibit R-1 or R-2, respectively, attached hereto (or such other form as
mutually agreed to by the Trustee and the Master Servicer or the Special Servicer, as applicable) and other documents necessary
or appropriate to enable the Master Servicer or the Special Servicer, as the case may be, to carry out its servicing and administrative
duties hereunder; provided, however, that the Trustee shall not be held responsible or liable for any acts of the
Master Servicer or the Special Servicer, or for any negligence with respect to, or misuse of, any such power of attorney by the
Master Servicer or the Special Servicer. Notwithstanding anything contained herein to the contrary, the Master Servicer or the
Special Servicer, as the case may be, shall not, without the Trustee’s written consent: (i) initiate any action, suit or
proceeding solely under the Trustee’s name without indicating the Master Servicer’s or the Special Servicer’s,
as the case may be, representative capacity (unless prohibited by any requirement of the applicable jurisdiction in which any such
action, suit or proceeding is brought and if so prohibited, in the manner required by such jurisdiction (provided that the
Master Servicer or the Special Servicer, as applicable, shall then provide five (5) Business Days’ written notice to the
Trustee of the initiation of such action, suit or proceeding (or such shorter time period as is reasonably required in the judgment
of the Master Servicer or the Special Servicer, as applicable, made in accordance with the Servicing Standard) prior to filing
such action, suit or proceeding), and shall not be required to obtain the Trustee’s consent or indicate the Master Servicer’s
or the Special Servicer’s, as applicable, representative capacity)) or (ii) take any action with the intent to cause, and
that actually causes, the Trustee to be required to be registered to do business in any state.


 


(c)       To
the extent the Master Servicer is permitted pursuant to the terms of the related Mortgage Loan documents or Companion Loan documents
(including any related Intercreditor Agreement) to exercise its discretion with respect to any action that requires Rating Agency
Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will not result in
the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if
any) or Loan-Specific Certificates (provided that such rating agency confirmation may be considered satisfied in the 





 






     -209-


     


    

 


same manner as any
Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25), the
Master Servicer shall require the costs of such Rating Agency Confirmation to be borne by the related Mortgagor. To the
extent the terms of the related Mortgage Loan documents or Companion Loan documents (including any related Intercreditor
Agreement) require the Mortgagor to bear the costs of any Rating Agency Confirmation or confirmation of any applicable rating
agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any
class of Serviced Companion Loan Securities (if any) or Loan-Specific Certificates (provided that such rating agency
confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied
with respect to the Certificates pursuant to Section 3.25), the Master Servicer shall not waive the requirement that
such costs and expenses be borne by the related Mortgagor. To the extent that the terms of the related Mortgage Loan
documents or Companion Loan documents (including any related Intercreditor Agreement) are silent as to who bears the costs of
any Rating Agency Confirmation or confirmation of any applicable rating agencies that such action will not result in the
downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if
any) or Loan-Specific Certificates (provided that such rating agency confirmation may be considered satisfied in the
same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section
3.25), the Master Servicer shall use reasonable efforts to have the Mortgagor bear such costs and expenses. The Master
Servicer shall not be responsible for the payment of such costs and expenses out of pocket other than as a Servicing
Advance.


 


(d)       The
relationship of each of the Master Servicer and the Special Servicer to the Trustee under this Agreement is intended by the parties
to be that of an independent contractor and not that of a joint venturer, partner or agent.


 


(e)       The
Master Servicer shall, to the extent permitted by the related Mortgage Loan documents or any related Companion Loan documents,
and consistent with the Servicing Standard, permit Escrow Payments to be invested only in Permitted Investments.


 


(f)
      Within sixty (60) days (or such shorter time period as is required by the terms of
the applicable Mortgage Loan documents) after the later of (i) the receipt thereof by the Master Servicer and (ii) the
Closing Date, (x) the applicable Mortgage Loan Seller pursuant to the Mortgage Loan Purchase Agreement shall notify each
provider of a letter of credit for each Mortgage Loan identified as having a letter of credit on the Mortgage Loan Schedule,
that the Master Servicer (in care of the Trustee, as titled in Section 2.01(b)) for the benefit of the
Certificateholders and any related Companion Holders shall be the beneficiary under each such letter of credit and (y) the
Master Servicer shall notify each lessor under a Ground Lease for each Mortgage Loan identified as subject to a leasehold
interest on the Mortgage Loan Schedule, that the Trust is the leasehold mortgagee, that any notices of default under such
Ground Lease and required to be delivered to the leasehold mortgagee pursuant to the terms of such Ground Lease shall be
delivered to the Master Servicer (who shall forward such notice to the Special Servicer), and that the Master Servicer or the
Special Servicer shall service the related Mortgage Loan for the benefit of the Certificateholders. If a letter of credit is
required to be drawn upon earlier than the date the applicable Mortgage Loan Seller has notified the provider of such letter
of credit pursuant to clause (x) of the immediately preceding sentence, such Mortgage Loan Seller shall


 






     -210-


     


    

 


cooperate with
the reasonable requests of the Master Servicer or Special Servicer in connection with making a draw under such letter of
credit. If the Mortgage Loan documents do not require the related Mortgagor to pay any costs and expenses relating to any
modifications to or assignment of the related letter of credit, then the applicable Mortgage Loan Seller shall pay such costs
and expenses as and to the extent required under the applicable Mortgage Loan Purchase Agreement. If the Mortgage Loan
documents require the related Mortgagor to pay any costs and expenses relating to any modifications to the related letter of
credit, and such Mortgagor fails to pay such costs and expenses after the Master Servicer has exercised reasonable efforts to
collect such costs and expenses from such Mortgagor, then the Master Servicer shall give the applicable Mortgage Loan Seller
notice of such failure and the amount of costs and expenses, and such Mortgage Loan Seller shall pay such costs and expenses
as and to the extent required under the applicable Mortgage Loan Purchase Agreement. The costs and expenses of any
modifications to Ground Leases shall be paid by the related Mortgagor. Neither the Master Servicer nor the Special Servicer
shall have any liability for the failure of any Mortgage Loan Seller to perform its obligations under the related Mortgage
Loan Purchase Agreement.


 


(g)      Notwithstanding
anything herein to the contrary, in no event shall the Master Servicer (or the Trustee, as applicable) make an Advance with respect
to any Companion Loan to the extent the related Serviced Mortgage Loan has been paid in full or is no longer included in the Trust
Fund.


 


(h)       Servicing
and administration of each Serviced Companion Loan shall continue hereunder and in accordance with the related Intercreditor Agreement
for so long as the corresponding Serviced Mortgage Loan or any related REO Property is part of the Trust Fund or for such longer
period as any amounts payable by the related Companion Holder to or for the benefit of the Trust or any party hereto, or payable
to the related Companion Holder, in accordance with the related Intercreditor Agreement remain due and owing.


 


(i)        The
Special Servicer agrees that upon the occurrence of a Servicing Transfer Event with respect to any Mortgage Loan or Serviced Whole
Loan, that is subject to or becomes subject to an Intercreditor Agreement in the future, it shall, subject to Section 3.19,
use commercially reasonable efforts to enforce, on behalf of the Trust, subject to the Servicing Standard and to the extent the
Special Servicer determines such action is in the best interests of the Trust, all rights conveyed to the Trustee pursuant to any
such Intercreditor Agreement. The costs and expenses incurred by the Special Servicer in connection with such enforcement shall
be paid as a Trust Fund expense or, subject to the terms of the applicable Intercreditor Agreement, (i) with respect to any Serviced
Pari Passu Whole Loan, pro rata and pari passu, by the Trust and Serviced Pari Passu Companion Loan, in accordance
with the respective outstanding principal balances of the related Serviced Pari Passu Mortgage Loan and Serviced Pari Passu Companion
Loan or (ii) with respect to any Serviced AB Whole Loan, first, by the related AB Subordinate Companion Loan (and with respect
to The Standard Highline NYC Whole Loan, first, by the Standard Highline Non-Trust Junior Subordinate Companion Loan, then,
by the Standard Highline Non-Trust Senior Subordinate Companion Loan and then, by the Standard Highline Trust Subordinate
Companion Loan, and correspondingly by the related Loan-Specific Certificates) and then, pro rata and pari passu,
by the Trust and any Serviced Pari Passu Companion Loan, in accordance with the respective outstanding principal balances of the
related Mortgage Loan and Serviced Pari Passu Companion Loan.


 



     -211-


     


    

 





(j)        Notwithstanding
anything herein to the contrary, the parties hereto acknowledge and agree that, to the extent required under the related Intercreditor
Agreement, the servicing and administration of a Serviced Whole Loan shall continue hereunder (but not with respect to making Advances)
even if the related Serviced Mortgage Loan is no longer part of the Trust Fund, until such time as a separate servicing agreement
is entered into in accordance with the related Intercreditor Agreement (it being acknowledged that neither the Master Servicer
nor the Special Servicer shall be obligated under a separate agreement to which it is not a party); provided that, other
than pursuant to Section 6.04 (and, with respect to Section 6.04, solely with respect to claims, losses, penalties,
fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, liabilities, fees and expenses incurred
in connection with a legal claim or action resulting from an action or inaction taken or not taken while the related Serviced Mortgage
Loan was part of the Trust Fund), no costs, expenses, losses or fees accruing with respect to such Serviced Whole Loan on and after
the date the related Serviced Mortgage Loan is no longer part of the Trust Fund shall be payable out of the Trust Fund and the
Master Servicer shall have no obligation to make any Advance on or after the date such Serviced Mortgage Loan ceases to be part
of the Trust Fund; provided, however, that if, in the case of any Serviced Whole Loan, the related Serviced Companion
Loan continues to be included in an Other Securitization, then for so long as a separate servicing agreement (pursuant to the related
Intercreditor Agreement) has not been entered into, the Master Servicer shall inform the related Other Servicer of any need to
make Servicing Advances with respect to a Serviced Whole Loan within three (3) Business Days of determining that such an Advance
is necessary or being notified that such an Advance is necessary, or in the case of a Servicing Advance that needs to be made on
an emergency or urgent basis, within one (1) Business Day. With respect to Servicing Advances made by any Other Servicer as contemplated
in the second proviso to the preceding sentence, the Master Servicer shall, from collections on the related Serviced Whole Loan
(but never out of general collections on the Mortgage Loans and REO Properties) received by the Master Servicer, reimburse the
Other Servicer for such Servicing Advances in the same manner and on the same level of priority as if such Servicing Advances had
been made by the Master Servicer hereunder.


 


(k)       Notwithstanding
anything herein to the contrary, the parties hereto acknowledge and agree that the Master Servicer’s and the Special Servicer’s
obligations and responsibilities hereunder and the Master Servicer’s and the Special Servicer’s authority with respect
to a Non-Serviced Mortgage Loan are limited by and subject to the terms of the related Non-Serviced Intercreditor Agreement and
the rights of the related Non-Serviced Master Servicer and Non-Serviced Special Servicer with respect thereto under the related
Non-Serviced PSA. The Master Servicer (or, with respect to any Specially Serviced Loan, the Special Servicer) shall use reasonable
efforts consistent with the Servicing Standards to enforce the rights of the Trustee (as holder of a Non-Serviced Mortgage Loan)
under the related Non-Serviced Intercreditor Agreement and Non-Serviced PSA.


 


(l)     
  The parties hereto acknowledge that each Non-Serviced Mortgage Loan is subject to the terms and conditions of the
related Non-Serviced Intercreditor Agreement and further acknowledge that, pursuant to the related Non-Serviced Intercreditor
Agreement, (i) the related Non-Serviced Mortgage Loan is to be serviced and administered by the related Non-Serviced Master Servicer
and Non-Serviced Special Servicer in accordance with the related Non-Serviced PSA, and (ii) in the event that (A) the related
Non-Serviced Companion Loan is no longer part of the Trust Fund created by the related Non-Serviced PSA and (B) the related Non- 


 






     -212-


     


    

 


Serviced Mortgage Loan is included in the Trust Fund, then, as set forth in the related Non-Serviced
Intercreditor Agreement, the related Non-Serviced Whole Loan shall continue to be serviced in accordance with the related
Non-Serviced PSA, until such time as a new servicing agreement has been agreed to by the parties to the related Non-Serviced
Intercreditor Agreement in accordance with the provisions of such agreement and confirmation has been obtained from the
Rating Agencies that such new servicing agreement would not result in a downgrade, qualification or withdrawal of the
then-current ratings of any Class of Certificates then outstanding.


 


(m)      Notwithstanding
anything herein to the contrary, the parties hereto acknowledge and agree that the Master Servicer’s and the Special Servicer’s
obligations and responsibilities hereunder and the Master Servicer’s and the Special Servicer’s authority with respect
to a Serviced Whole Loan are limited by, and subject to, the terms of the related Intercreditor Agreement. The Master Servicer
(or, if a Serviced Whole Loan becomes a Specially Serviced Loan, the Special Servicer) shall use reasonable efforts consistent
with the Servicing Standard to obtain the benefits of the rights of the Trust (as holder of the related Serviced Mortgage Loan)
under the related Intercreditor Agreement. In the event of any conflict between this Agreement and the related Intercreditor Agreement,
the provisions of the related Intercreditor Agreement shall control.


 


(n)       In
connection with the securitization of any Serviced Companion Loan (in each case, only while it is a Serviced Companion Loan), upon
the request of (and at the expense of) the related Serviced Companion Noteholder (or its designee), each of the Master Servicer,
the Special Servicer (if such Serviced Companion Loan is a Specially Serviced Loan) and the Trustee, as applicable, shall use reasonable
efforts to cooperate with such Serviced Companion Noteholder in attempting to cause the related Mortgagor to provide information
relating to such Whole Loan and the related notes, and that such holder reasonably determines to be necessary or appropriate, for
inclusion in any disclosure document(s) relating to such Other Securitization.


 


(o)       The
parties hereto acknowledge and agree that the servicing and administration of the Trust Subordinate Companion Loans shall continue
hereunder by the Master Servicer and the Special Servicer even if the related Mortgage Loan is no longer part of the Trust Fund
subject to the provisions of Section 3.31(g).


 


Section
3.02     Collection of Mortgage Loan Payments. (a) Each of the Master Servicer and the Special Servicer shall use
reasonable efforts consistent with the Servicing Standard to collect all payments called for under the terms and provisions
of the Mortgage Loans and the Companion Loans it is obligated to service hereunder, and shall follow such collection
procedures as are consistent with this Agreement (including, without limitation, the Servicing Standard); provided
that with respect to each Mortgage Loan that has an Anticipated Repayment Date, so long as the related Mortgagor is in
compliance with each provision of the related Mortgage Loan documents, the Master Servicer and the Special Servicer shall not
take any enforcement action with respect to the failure of the related Mortgagor to make any payment of Excess Interest,
other than requests for collection, until the Maturity Date of the related Mortgage Loan or until the outstanding principal
balance of such Mortgage Loan (exclusive of any portion representing accrued Excess Interest) has been paid in full); provided, further,
that the Master Servicer or the Special Servicer, as the case may be, may take action to enforce the


 






     -213-


     


    

 


Trust’s right to
apply excess cash flow to principal in accordance with the terms of the Mortgage Loan documents. The Master Servicer or the
Special Servicer, as applicable, may in its discretion waive any Penalty Charge in connection with any delinquent payment on
a Mortgage Loan and Companion Loan that it is obligated to service hereunder.


 


(b)       (i)
All amounts collected by or on behalf of the Trust in respect of a Mortgage Loan shall be applied to amounts due and owing under
the Mortgage Loan documents (including for principal and accrued and unpaid interest) in accordance with the express provisions
of the Mortgage Loan documents; provided, however, that absent express provisions in the related Mortgage Loan documents
(including any related Intercreditor Agreement) or to the extent otherwise agreed to by the related Mortgagor in connection with
the workout of a Mortgage Loan, all amounts collected by or on behalf of the Trust in respect of a Mortgage Loan in the form of
payments from the related Mortgagor, Liquidation Proceeds or Insurance and Condemnation Proceeds under the Mortgage Loan (in the
case of each Serviced Whole Loan, exclusive of amounts payable to any applicable Companion Loan pursuant to the terms of the related
Intercreditor Agreement) shall be applied in the following order of priority:


 


first, as a recovery
of any unreimbursed Advances (including any Workout-Delayed Reimbursement Amount) with respect to the related Mortgage Loan and
unpaid interest at the Reimbursement Rate on such Advances and, if applicable, unreimbursed and unpaid additional expenses of the
Trust;


 


second, as a recovery
of Nonrecoverable Advances and any interest on those Nonrecoverable Advances at the Reimbursement Rate, to the extent previously
paid or reimbursed from principal collections on the Mortgage Loans;


 


third, to the
extent not previously so allocated pursuant to clause first or second above, as a recovery of accrued and
unpaid interest on such Mortgage Loan to the extent of the excess of (i) unpaid interest (exclusive of Default Interest and Excess
Interest) accrued on such Mortgage Loan at the related Mortgage Rate in effect from time to time through the end of the applicable
mortgage interest accrual period, over (ii) after taking into account any allocations pursuant to clause fifth below on
earlier dates, the aggregate portion of the accrued and unpaid interest described in subclause (i) of this clause third
that either (A) was not advanced because of the reductions (if any) in the amount of related P&I Advances for such Mortgage
Loan that have occurred in connection with related Appraisal Reduction Amounts or (B) accrued at the related Net Mortgage Rate
on the portion of the Stated Principal Balance of such Mortgage Loan equal to any related Collateral Deficiency Amount in effect
from time to time and as to which no P&I Advance was made;


 


fourth, to the
extent not previously allocated pursuant to clause first or second, as a recovery of principal of such Mortgage Loan
then due and owing, including by reason of acceleration of such Mortgage Loan following a default thereunder (or, if the Mortgage
Loan has been liquidated, as a recovery of principal to the extent of its entire remaining unpaid principal balance);


 


fifth, as a recovery
of accrued and unpaid interest on such Mortgage Loan to the extent of the sum of (A) the cumulative amount of the reductions (if
any) in the amount of

related P&I Advances for such Mortgage Loan that have occurred in connection with related Appraisal Reduction
Amounts, plus (B) any unpaid interest (exclusive of Default Interest and Excess Interest) that accrued at the related Net Mortgage
Rate on the portion of the Stated Principal Balance of such Mortgage Loan equal to any related Collateral Deficiency Amount in
effect from time to time and as to which no P&I Advance was made (to the extent collections have not been allocated as recovery
of such accrued and unpaid interest pursuant to this clause fifth on earlier dates);


 


sixth, as a recovery
of amounts to be currently allocated to the payment of, or escrowed for the future payment of, real estate taxes, assessments and
insurance premiums and similar items relating to such Mortgage Loan;


 


seventh, as a
recovery of any other reserves to the extent then required to be held in escrow with respect to such Mortgage Loan;

ninth, as a recovery
of any late payment charges and Default Interest then due and owing under such Mortgage Loan;


 


tenth, as a recovery
of any assumption fees, assumption application fees and Modification Fees then due and owing under such Mortgage Loan;


 


eleventh, as a
recovery of any other amounts then due and owing under such Mortgage Loan other than remaining unpaid principal (if both consent
fees and Operating Advisor Consulting Fees are due and owing, first, allocated to consent fees and then, allocated
to Operating Advisor Consulting Fees);


 


twelfth, as a
recovery of any remaining principal of such Mortgage Loan to the extent of its entire remaining unpaid principal balance; and


 


thirteenth, in
the case of an ARD Loan after the related Anticipated Repayment Date, any accrued but unpaid Excess Interest;


 


provided that to the extent required
under the REMIC Provisions, payments or proceeds received (or receivable by exercise of the lender’s rights under the related
Mortgage Loan documents) with respect to any partial release of a Mortgaged Property (including in connection with a condemnation)
at a time when the loan to value ratio of the related Mortgage Loan or Serviced Whole Loan, as applicable, exceeds 125%, or would
exceed 125% following any partial release (based solely on the value of real property and excluding personal property and going
concern value, if any, unless otherwise permitted under the applicable REMIC Provisions as evidenced by an Opinion of Counsel to
the Trustee) must be collected and allocated to reduce the principal balance of the Mortgage Loan or Serviced Whole Loan) in the
manner required by the REMIC Provisions; provided, further, that if a Non-Serviced Mortgage Loan and any related
Non-Serviced Companion Loan comprising a Non-Serviced Whole Loan become REO Loans, the treatment of the foregoing amounts with
respect to such Non-Serviced Whole Loan shall be subject to the terms of the related Non-Serviced Intercreditor Agreement and Non-Serviced
PSA,

in that order; provided, further, that with respect to each Mortgage Loan related to a Serviced Whole Loan,
amounts collected with respect to the related Serviced Whole Loan shall be allocated first pursuant to the terms of the related
Intercreditor Agreement and then, any amounts allocated to the related Serviced Mortgage Loan shall be subject to application as
described above.


 


(ii)         Collections
by or on behalf of the Trust in respect of any REO Property (exclusive of the amounts to be allocated to the payment of the costs
of operating, managing, leasing, maintaining and disposing of such REO Property and, if applicable, in the case of each Serviced
Whole Loan, exclusive of any amounts payable to the holder(s) of the related Companion Loan(s), as applicable, pursuant to the
terms of the related Intercreditor Agreement) shall be applied in the following order of priority:


 


first, as a recovery
of any unreimbursed Advances (including any Workout-Delayed Reimbursement Amount) with respect to the related Mortgage Loan and
interest at the Reimbursement Rate on all Advances and, if applicable, unreimbursed and unpaid additional Trust Fund expenses with
respect to the related Mortgage Loan;


 


second, as a recovery
of Nonrecoverable Advances and any interest on those Nonrecoverable Advances at the Reimbursement Rate, to the extent previously
paid or reimbursed from principal collections on the Mortgage Loans;


 


third, to the
extent not previously so allocated pursuant to clause first or second above, as a recovery of accrued and unpaid
interest on such Mortgage Loan to the extent of the excess of (i) unpaid interest (exclusive of Default Interest and Excess Interest)
accrued on such Mortgage Loan at the related Mortgage Rate in effect from time to time through the end of the applicable mortgage
interest accrual period, over (ii) after taking into account any allocations pursuant to fifth below or clause fifth
of Section 3.02(b) on earlier dates, the aggregate portion of the accrued and unpaid interest described in subclause
(i) of this clause third that either (A) was not advanced because of the reductions (if any) in the amount of related
P&I Advances for such Mortgage Loan that have occurred in connection with related Appraisal Reduction Amounts or (B) accrued
at the related Net Mortgage Rate on the portion of the Stated Principal Balance of such Mortgage Loan equal to any related Collateral
Deficiency Amount in effect from time to time and as to which no P&I Advance was made;


 


fourth, to the
extent not previously allocated pursuant to clause first or second above, as a recovery of principal of such Mortgage
Loan to the extent of its entire unpaid principal balance;


 


fifth, as a recovery
of accrued and unpaid interest on such Mortgage Loan to the extent of the sum of (A) the cumulative amount of the reductions (if

have not been allocated as recovery
of accrued and unpaid interest pursuant to this clause fifth or clause fifth of Section 3.02(b) on earlier
dates);


 


sixth, as a recovery
of any Yield Maintenance Charge then due and owing under such Mortgage Loan;


 


seventh, as a
recovery of any late payment charges and Default Interest then due and owing under such Mortgage Loan;


 


eighth, as a recovery

allocated to Operating Advisor Consulting Fees); and


 


tenth, in the
case of an ARD Loan after the related Anticipated Repayment Date, any accrued but unpaid Excess Interest;


 


provided that if a Non-Serviced
Mortgage Loan and any related Non-Serviced Companion Loan comprising a Non-Serviced Whole Loan becomes an REO Loan, the treatment
of the foregoing amounts with respect to such Non-Serviced Whole Loan shall be subject to the terms of the related Non-Serviced
Intercreditor Agreement and Non-Serviced PSA, in that order; provided, further, that with respect to each Mortgage
Loan related to a Serviced Whole Loan, amounts collected with respect to the related Serviced Whole Loan shall be allocated first
pursuant to the terms of the related Intercreditor Agreement and then, any amounts allocated to the related Serviced Mortgage Loan
shall be subject to application as described above.


 


(iii)        Notwithstanding
clauses (i) and (ii) above, such provisions shall not be deemed to affect the priority of distributions of payments
pursuant to the provisions of this Agreement. To the extent that such amounts are paid by a party other than a Mortgagor, such
amounts shall be deemed to have been paid in respect of a purchase of all or part of the Mortgaged Property (in the case of Insurance
and Condemnation Proceeds or Liquidation Proceeds) and then paid by the Mortgagor under the Mortgage Loan or Companion Loan, as
applicable, in accordance with Section 3.02(b)(ii) above.


 


(c)       To
the extent consistent with the terms of the Mortgage Loans (and, with respect to each Serviced Whole Loan, the related Serviced
Companion Loan and the related Intercreditor Agreement) and applicable law, the Master Servicer shall apply all Insurance and Condemnation
Proceeds it receives on a day other than the Due Date to amounts due and owing under the related Mortgage Loan or Companion Loan
as if such Insurance and Condemnation Proceeds were received on the Due Date immediately succeeding the month in which Insurance
and Condemnation Proceeds were received and otherwise in accordance with Section 3.02(b)(ii) above.


 


(d)       In
the event that the Master Servicer or the Special Servicer receives Excess Interest prior to the Determination Date for any Collection
Period, or receives notice


 






     -217-


     


    

  


from the related Mortgagor that the Master Servicer or the Special Servicer will be receiving Excess
Interest prior to the Determination Date for any Collection Period, the Master Servicer or the Special Servicer, as the case may
be, shall notify the Trustee and Certificate Administrator two (2) Business Days prior to the related Distribution Date in the
CREFC® Loan Periodic Update File. None of the Master Servicer, the Special Servicer, the Certificate Administrator
or the Trustee shall be responsible for any failure of the related Mortgagor to pay any such Excess Interest or prepayment penalty.
The preceding statements shall not, however, be construed to limit the provisions of Section 3.02(a).


 


(e)       With
respect to any Mortgage Loan (or a Trust Subordinate Companion Loan, as applicable) in connection with which the Mortgagor was
required to escrow funds or to post a letter of credit related to obtaining certain performance objectives described in the applicable
Mortgage Loan documents or Trust Subordinate Companion Loan documents, as applicable, the Master Servicer shall, to the extent
consistent with the Servicing Standard, hold such escrows, letters of credit and proceeds thereof as additional collateral and
not apply such items to reduce the principal balance of such Mortgage Loan or Serviced Companion Loan, unless otherwise required
to do so pursuant to the applicable Mortgage Loan documents, applicable law or court order.


 


(f)        Promptly
following the Closing Date, and, with respect to any Servicing Shift Mortgage Loan, promptly following receipt of written notice
by the Certificate Administrator of the related Servicing Shift Securitization Date, in the case of any Non-Serviced Whole Loan,
the Certificate Administrator shall send written notice (in the form attached hereto as Exhibit T) to the related Non-Serviced
Master Servicer (with a copy to any other applicable party set forth on the schedule of addresses to Exhibit T) stating
that, as of such date, the Trustee is the holder of the related Non-Serviced Mortgage Loan and directing such Non-Serviced Master
Servicer to remit to the Master Servicer all amounts payable to, and to forward, deliver or otherwise make available, as the case
may be, to the Master Servicer all reports, statements, documents, communications and other information that are to be forwarded,
delivered or otherwise made available to, the holder of such Non-Serviced Mortgage Loan under the related Non-Serviced Intercreditor
Agreement and the related Non-Serviced PSA. The Master Servicer shall, within two (2) Business Days of receipt of properly identified
funds, deposit into the Collection Account all amounts received with respect to the related Non-Serviced Mortgage Loan, the related
Non-Serviced Mortgaged Property or any related REO Property.


 


Section
3.03      Collection of Taxes, Assessments and Similar Items; Servicing Accounts. (a) The
Master Servicer shall establish and maintain one or more accounts (the “Servicing Accounts”), into which
all Escrow Payments shall be deposited and retained, and shall administer such Servicing Accounts in accordance with the
Mortgage Loan documents and, if applicable, the Companion Loan documents, as the case may be. Any Servicing Account related
to a Serviced Whole Loan shall be held for the benefit of the Certificateholders and the related Serviced Companion
Noteholder collectively, but this shall not be construed to modify respective interests of either noteholder therein as set
forth in the related Intercreditor Agreement. Amounts on deposit in Servicing Accounts may only be invested in accordance
with the terms of the related Mortgage Loan documents and Companion Loan documents, as applicable, or in Permitted
Investments in accordance with the provisions of Section 3.06. Servicing Accounts shall be Eligible Accounts to the
extent permitted by the terms of the related


 






     -218-


     


    

 


Mortgage Loan documents. Withdrawals of amounts so deposited from a
Servicing Account may be made only to: (i) effect payment of items for which Escrow Payments were collected and comparable
items; (ii) reimburse the Trustee and then the Master Servicer, if applicable, for any Servicing Advances; (iii) refund to
Mortgagors any sums as may be determined to be overages; (iv) pay interest to Mortgagors on balances in the Servicing
Account, if required by applicable law or the terms of the related Mortgage Loan or Companion Loan and as described below or,
if not so required, to the Master Servicer; (v) after the occurrence of an event of default under the related Mortgage Loan
or Companion Loan, apply amounts to the indebtedness under the applicable Mortgage Loan or Companion Loan; (vi) withdraw
amounts deposited in error; (vii) pay Penalty Charges to the extent permitted by the related Mortgage Loan documents; or
(viii) clear and terminate the Servicing Account at the termination of this Agreement in accordance with Section 9.01.
As part of its servicing duties, the Master Servicer shall pay or cause to be paid to the Mortgagors interest on funds in
Servicing Accounts, to the extent required by law or the terms of the related Mortgage Loan or Companion Loan; provided, however,
that in no event shall the Master Servicer be required to remit to any Mortgagor any amounts in excess of actual net
investment income or funds in the related Servicing Account. If allowed by the related Mortgage Loan documents and applicable
law, the Master Servicer may charge the related Mortgagor an administrative fee for maintenance of the Servicing
Accounts.


 


(b)       The
Special Servicer, in the case of REO Loans (other than any REO Loan succeeding a Non-Serviced Mortgage Loan), and the Master Servicer,
in the case of all other Mortgage Loans (other than a Non-Serviced Mortgage Loan) and each Serviced Companion Loan, shall maintain
accurate records with respect to each related Mortgaged Property reflecting the status of real estate taxes, assessments and other
similar items that are or may become a lien thereon and the status of insurance premiums and any ground rents payable in respect
thereof. The Special Servicer, in the case of REO Loans (other than any REO Loan succeeding a Non-Serviced Mortgage Loan), and
the Master Servicer, in the case of all other Mortgage Loans (other than a Non-Serviced Mortgage Loan) and each Serviced Companion
Loan, shall use reasonable efforts consistent with the Servicing Standard to obtain, from time to time, all bills for the payment
of such items (including renewal premiums) and shall effect payment thereof from the REO Account or by the Master Servicer as Servicing
Advances prior to the applicable penalty or termination date and, in any event, prior to the institution of foreclosure or similar
proceedings with respect to the related Mortgaged Property for nonpayment of such items, employing for such purpose Escrow Payments
(which shall be so applied by the Master Servicer at the written direction of the Special Servicer in the case of REO Loans) as
allowed under the terms of the related Mortgage Loan (other than a Non-Serviced Mortgage Loan) and Companion Loan. Other than with
respect to any Non-Serviced Mortgage Loan, the Master Servicer shall service and administer any reserve accounts (including monitoring,
maintaining or changing the amounts of required escrows) in accordance with the terms of such Mortgage Loan and the related Serviced
Companion Loan and the Servicing Standard. To the extent that a Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any
related Companion Loan does not require a Mortgagor to escrow for the payment of real estate taxes, assessments, insurance premiums,
ground rents (if applicable) and similar items, the Special Servicer, in the case of REO Loans, and the Master Servicer, in the
case of all other Mortgage Loans or Companion Loan that it is responsible for servicing hereunder, shall use efforts consistent
with the Servicing Standard to cause the Mortgagor to comply with its obligation to make payments in respect of such items at the
time they first become due and, in any event, prior to the institution of


 






     -219-


     


    

 


foreclosure or similar proceedings with respect to the
related Mortgaged Property for nonpayment of such items.


 


(c)       In
accordance with the Servicing Standard and for each Mortgage Loan (other than any Non-Serviced Mortgage Loans) and each Serviced
Whole Loan, the Master Servicer shall advance all such funds as are necessary for the purpose of effecting the payment of (i) real
estate taxes, assessments and other similar items that are or may become a lien thereon, (ii) ground rents (if applicable) and
(iii) premiums on Insurance Policies, in each instance if and to the extent Escrow Payments collected from the related Mortgagor
(or related REO Revenues, if applicable) are insufficient to pay such item when due and the related Mortgagor has failed to pay
such item on a timely basis, and provided, however, that the particular advance would not, if made, constitute a
Nonrecoverable Servicing Advance and provided, further, however, that with respect to the payment of taxes
and assessments, the Master Servicer shall not be required to make such advance until the later of (i) five (5) Business Days after
the Master Servicer, the Special Servicer, the Certificate Administrator or the Trustee, as the case may be, has received confirmation
that such item has not been paid and (ii) the date prior to the date after which any penalty or interest would accrue in respect
of such taxes or assessments. The Special Servicer shall give the Master Servicer and the Trustee no less than five (5) Business
Days’ written (facsimile or electronic) notice before the date on which the Master Servicer is requested to make any Servicing
Advance with respect to a given Specially Serviced Loan or REO Property; provided, however, that only two (2) Business
Days’ written (facsimile or electronic) notice shall be required in respect of Servicing Advances required to be made on
an emergency or urgent basis provided, further, that the Special Servicer shall not be entitled to make such a request
(other than for Servicing Advances required to be made on an urgent or emergency basis) more frequently than once per calendar
month (although such request may relate to more than one Servicing Advance). The Master Servicer may pay the aggregate amount of
such Servicing Advances listed on a monthly request to the Special Servicer, in which case the Special Servicer shall remit such
Servicing Advances to the ultimate payees. The Special Servicer shall have no obligation to make any Servicing Advances; provided
that in an urgent or emergency situation requiring the making of a Servicing Advance, the Special Servicer may make a Servicing
Advance. Within five (5) Business Days of making such a Servicing Advance, the Special Servicer shall deliver to the Master Servicer
request for reimbursement for such Servicing Advance, along with all information and documentation in the Special Servicer’s
possession regarding the subject Servicing Advance as the Master Servicer may reasonably request, and the Master Servicer shall
be obligated, out of such Master Servicer’s own funds, to reimburse the Special Servicer for any unreimbursed Servicing Advances
(other than Nonrecoverable Servicing Advances) made by the Special Servicer pursuant to the terms hereof), together with interest
thereon at the Reimbursement Rate from the date made to, but not including, the date of reimbursement. Such reimbursement and any
accompanying payment of interest shall be made within five (5) Business Days of the written request therefor pursuant to the preceding
sentence by wire transfer of immediately available funds to an account designated in writing by the Special Servicer. Upon the
Master Servicer’s reimbursement to the Special Servicer of any Servicing Advance and payment to the Special Servicer of interest
thereon, all in accordance with this Section 3.03, the Master Servicer shall for all purposes of this Agreement be deemed
to have made such Servicing Advance at the same time as the Special Servicer actually made such Servicing Advance, and accordingly,
the Master Servicer shall be entitled to be reimbursed for such Servicing Advance, together with interest thereon at the Reimbursement
Rate, at the same


 






     -220-


     


    

 


time, in the same manner and to the same extent as the Master Servicer would otherwise have been entitled if
it had actually made such Servicing Advance at the time the Special Servicer did. Notwithstanding the foregoing provisions of this
Section 3.03, the Master Servicer shall not be required to reimburse the Special Servicer for any such Servicing Advance
if the Master Servicer determines in accordance with the Servicing Standard that such Servicing Advance, although not characterized
by the Special Servicer as a Nonrecoverable Servicing Advance, is in fact a Nonrecoverable Servicing Advance. The Master Servicer
shall notify the Special Servicer in writing of such determination and, if applicable, such Nonrecoverable Servicing Advance shall
be reimbursed to the Special Servicer pursuant to Section 3.05 of this Agreement.


 


Any request by the Special
Servicer that the Master Servicer make a Servicing Advance shall be deemed to be a determination by the Special Servicer that such
requested Servicing Advance is not a Nonrecoverable Servicing Advance, and the Master Servicer shall be entitled to conclusively
rely on such determination, provided that the determination shall not be binding on the Master Servicer or Trustee. On the
first Business Day after the Determination Date for the related Distribution Date, the Special Servicer shall report to the Master
Servicer if the Special Servicer determines any Servicing Advance previously made by the Master Servicer with respect to a Specially
Serviced Loan or REO Loan is a Nonrecoverable Servicing Advance. The Master Servicer shall be entitled to conclusively rely on
such a determination, but such determination shall not be binding upon the Master Servicer, and shall in no way limit the ability
of the Master Servicer in the absence of such determination to make its own determination that any Advance is a Nonrecoverable
Advance. If the Special Servicer makes a determination that only a portion of, and not all of, any previously made or proposed
Servicing Advance is a Nonrecoverable Advance, the Master Servicer shall have the right to make its own subsequent determination
that any remaining portion of any such previously made or proposed Servicing Advance is a Nonrecoverable Advance. All such Advances
shall be reimbursable in the first instance from related collections from the Mortgagors and further as provided in Section
3.05(a). No costs incurred by the Master Servicer or the Special Servicer in effecting the payment of real estate taxes, assessments
and, if applicable, ground rents on or in respect of the Mortgaged Properties shall, for purposes hereof, including, without limitation,
the Certificate Administrator’s calculation of monthly distributions to Certificateholders, be added to the unpaid principal
balances of the related Mortgage Loans or any related Serviced Companion Loan, if applicable, notwithstanding that the terms of
such Mortgage Loans or related Serviced Companion Loan, if applicable, so permit. If the Master Servicer fails to make any required
Servicing Advance as and when due (including any applicable cure periods), to the extent the Trustee has actual knowledge of such
failure, the Trustee shall make such Servicing Advance pursuant to Section 7.05. Notwithstanding anything herein to the
contrary, no Servicing Advance shall be required hereunder if such Servicing Advance would, if made, constitute a Nonrecoverable
Servicing Advance. In addition, the Master Servicer shall consider Unliquidated Advances in respect of prior Servicing Advances
for purposes of nonrecoverability determinations. The Special Servicer shall have no obligation to make any Servicing Advances
under this Agreement.


 


Notwithstanding the foregoing
provisions of this Section 3.03(c), the Master Servicer shall not be required to reimburse the Special Servicer out of its
own funds for, or to make at the direction of the Special Servicer, any Servicing Advance if the Master Servicer determines that
such Servicing Advance, although not characterized by the Special Servicer as a


 






     -221-


     


    

 


Nonrecoverable Servicing Advance, is a Nonrecoverable
Servicing Advance. The Master Servicer shall notify the Special Servicer in writing of such determination and, if applicable, such
Nonrecoverable Servicing Advance shall be reimbursed to the Special Servicer pursuant to Section 3.05(a).


 


Notwithstanding anything
to the contrary contained in this Section 3.03(c), the Master Servicer may in its good faith judgment elect (but shall not
be required unless directed by the Special Servicer with respect to Specially Serviced Loans and REO Loans) to make a payment from
amounts on deposit in the Collection Account (or any Companion Distribution Account maintained as a subaccount thereof by a Companion
Paying Agent, if applicable) (which shall be deemed first made from amounts distributable as principal and then from
all other amounts comprising general collections) to pay for certain expenses set forth below notwithstanding that the Master Servicer
(or the Special Servicer, as applicable) has determined that a Servicing Advance with respect to such expenditure would be a Nonrecoverable
Servicing Advance (unless, with respect to Specially Serviced Loans or REO Loans, the Special Servicer has notified the Master
Servicer to not make such expenditure), where making such expenditure would prevent (i) the related Mortgaged Property from being
uninsured or being sold at a tax sale or (ii) any event that would cause a loss of the priority of the lien of the related Mortgage,
or the loss of any security for the related Mortgage Loan or Serviced Companion Loan; provided that in each instance, the
Master Servicer or the Special Servicer, as applicable, determines in accordance with the Servicing Standard (as evidenced by an
Officer’s Certificate delivered to the Trustee) that making such expenditure is in the best interest of the Certificateholders
(and, if applicable, the Companion Holders), all as a collective whole (taking into account the subordinate or pari passu
nature of any Companion Loans, as the case may be). The Master Servicer or Trustee may elect to obtain reimbursement of Nonrecoverable
Servicing Advances from the Trust pursuant to the terms of Section 3.17(c). The parties acknowledge that pursuant to the
applicable Non-Serviced PSA, the applicable Non-Serviced Master Servicer is obligated to make servicing advances with respect to
the related Non-Serviced Whole Loan. The applicable Non-Serviced Master Servicer shall be entitled to reimbursement for Nonrecoverable
Servicing Advances with respect to such Non-Serviced Whole Loan (with, in each case, any accrued and unpaid interest thereon provided
for under the applicable Non-Serviced PSA) in the manner set forth in the applicable Non-Serviced PSA and the applicable Non-Serviced
Intercreditor Agreement.


 


(d)       In
connection with its recovery of any Servicing Advance out of the Collection Account (or any Companion Distribution Account maintained
as a subaccount thereof by the Companion Paying Agent, if applicable) pursuant to Section 3.05(a), the Trustee, the Special
Servicer and then the Master Servicer, as the case may be and in that order, shall be entitled to receive, out of any amounts then
on deposit in the Collection Account interest at the Reimbursement Rate in effect from time to time, accrued on the amount of such
Servicing Advance from the date made to, but not including, the date of reimbursement. Subject to Section 3.17(c), the Master
Servicer shall reimburse itself, the Special Servicer or the Trustee, as the case may be, for any outstanding Servicing Advance
as soon as practically possible after funds available for such purpose are deposited in the Collection Account (or any Companion
Distribution Account maintained as a subaccount thereof by the Companion Paying Agent, if applicable) subject to the Master Servicer’s
or the Trustee’s options and rights to defer recovery of such amounts as provided herein; provided, however,
that such Master Servicer’s or Trustee’s


 






     -222-


     


    

 


options and rights to defer recovery of such amounts shall not alter the Master
Servicer’s obligation to reimburse the Special Servicer for any outstanding Servicing Advance as provided for in this sentence.
To the extent amounts on deposit in the Companion Distribution Account with respect to the related Companion Loan are insufficient
for any such reimbursement, the Master Servicer shall use reasonable efforts in accordance with the Servicing Standard to enforce
the rights of the holder of the related Mortgage Loan under the related Intercreditor Agreement to obtain any reimbursement available
from the holder of the related Companion Loan.


 


(e)       To
the extent an operations and maintenance plan is required to be established and executed pursuant to the terms of a Mortgage Loan
(other than a Non-Serviced Mortgage Loan) or Trust Subordinate Companion Loan, the Master Servicer shall request from the Mortgagor
written confirmation thereof within a reasonable time after the later of the Closing Date and the date as of which plan is required
to be established or completed. To the extent any repairs, capital improvements, actions or remediations are required to have been
taken or completed pursuant to the terms of the Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Trust Subordinate Companion
Loan, the Master Servicer shall request from the Mortgagor written confirmation of such actions and remediations within a reasonable
time after the later of the Closing Date and the date as of which action or remediations are required to be or to have been taken
or completed. To the extent a Mortgagor shall fail to promptly respond to any inquiry described in this Section 3.03(e),
the Master Servicer shall report any such failure to the Special Servicer within a reasonable time after the date as of which actions
or remediations are required to be or to have been taken or completed.


 


Section
3.04 The Collection Account, the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the
Companion Distribution Account, the Interest Reserve Account, the Excess Interest Distribution Account, the Regular Interest
Distribution Account, the Gain-on-Sale Reserve Account and the Trust Subordinate Companion Loan REMIC Distribution
Accounts. (a) The Master Servicer shall establish and maintain, or cause to be established and maintained, a Collection
Account in which the Master Servicer shall deposit or cause to be deposited, in no event later than the second Business Day
following receipt of available and properly identified funds (in the case of payments by Mortgagors or other collections on
the Mortgage Loans or Companion Loans), except as otherwise specifically provided herein, the following payments and
collections received or made by or on behalf of it subsequent to the Cut-off Date (other than in respect of principal and
interest on the Mortgage Loans or Companion Loans due and payable on or before the Cut-off Date, which payments shall be
delivered promptly to the appropriate Mortgage Loan Seller or its respective designee and other than any amounts received
from Mortgagors which are received in connection with the purchase of defeasance collateral), or payments (other than
Principal Prepayments) received by it on or prior to the Cut-off Date but allocable to a period subsequent thereto:


 


(i)          all
payments on account of principal, including Principal Prepayments on the Mortgage Loans or principal prepayments on Serviced Companion
Loans;


 


(ii)         all
payments on account of interest on the Mortgage Loans or the Serviced Companion Loans, including Excess Interest, Yield Maintenance
Charges and Default Interest;


 



     -223-


     


    

 





(iii)        late
payment charges and other Penalty Charges to the extent required to offset interest on Advances and additional expenses of the
Trust (other than Special Servicing Fees, Workout Fees or Liquidation Fees) as required by Section 3.11(d);


 


(iv)        all
Insurance and Condemnation Proceeds and Liquidation Proceeds (other than Gain-on-Sale Proceeds or Non-Serviced Gain-on-Sale Proceeds)
received in respect of any Mortgage Loan, Serviced Companion Loan or REO Property (other than (A) Liquidation Proceeds that are
received in connection with the purchase by the Master Servicer, the Special Servicer, the Holder of the majority of the Controlling
Class, or the Holders of the Class R Certificates of all the Mortgage Loans, the Trust Subordinate Companion Loans and any REO
Properties in the Trust Fund and that are to be deposited in the Lower-Tier REMIC Distribution Account pursuant to Section 9.01
and (B) any proceeds that are received in connection with the purchase, if any, of a Serviced Pari Passu Companion Loan from a
securitization by the related mortgage loan seller, which shall be paid directly to the servicer of such securitization) together
with any recovery of Unliquidated Advances in respect of the related Mortgage Loans;


 


(v)         any
amounts required to be transferred from the REO Account pursuant to Section 3.14(c);


 


(vi)        any
amounts required to be deposited by the Master Servicer pursuant to Section 3.06 in connection with losses incurred with
respect to Permitted Investments of funds held in the Collection Account; and


 


(vii)       any
amounts required to be deposited by the Master Servicer or the Special Servicer pursuant to Section 3.07(b) in connection
with losses resulting from a deductible clause in a blanket hazard or master single interest policy.


 


Notwithstanding the foregoing
requirements, the Master Servicer need not deposit into the Collection Account any amount that the Master Servicer would be authorized
to withdraw immediately from such account in accordance with the terms of Section 3.05 and shall be entitled to instead
immediately pay such amount directly to the Person(s) entitled thereto; provided that such amounts shall be applied in accordance
with the terms hereof and shall be reported as if deposited in such Collection Account and then withdrawn.


 


The foregoing requirements
for deposit in the Collection Account shall be exclusive, it being understood and agreed that, without limiting the generality
of the foregoing, actual payments from Mortgagors in the nature of Escrow Payments, charges for beneficiary statements or demands,
assumption fees, modification fees, extension fees, defeasance fees, amounts collected for Mortgagor checks returned for insufficient
funds or other amounts the Master Servicer or the Special Servicer would be entitled to retain as additional servicing compensation
need not be deposited by the Master Servicer in the Collection Account. If the Master Servicer shall deposit in the Collection
Account any amount not required to be deposited therein, it may at any time withdraw such amount from the Collection Account, any
provision herein to the contrary notwithstanding. Assumption, extension and modification fees actually received from Mortgagors
on Specially Serviced Loans shall be promptly delivered to the Special Servicer as additional servicing compensation.


 



     -224-


     


    

 





Upon receipt of any of
the foregoing amounts in clauses (i) through (iv) above with respect to any Specially Serviced Loans, the Special
Servicer shall remit within one (1) Business Day such amounts to the Master Servicer for deposit into the Collection Account, in
accordance with this Section 3.04(a). Any such amounts received by the Special Servicer with respect to an REO Property
shall be deposited by the Special Servicer into the REO Account and remitted to the Master Servicer for deposit into the Collection
Account, pursuant to Section 3.14(c). With respect to any such amounts paid by check to the order of the Special Servicer,
the Special Servicer shall endorse without recourse or warranty such check to the order of the Master Servicer and shall promptly
deliver any such check to the Master Servicer by overnight courier. Funds in the Collection Account may only be invested in Permitted
Investments in accordance with the provisions of Section 3.06. As of the Closing Date, the Collection Account for the Master
Servicer shall be located at the offices of KeyBank National Association. The Master Servicer shall give notice to the Trustee,
the Special Servicer, the Certificate Administrator and the Depositor of the new location of the Collection Account prior to any
change thereof.


 


For purposes of determining
amounts to be deposited in the Collection Account in respect of any Trust Subordinate Companion Loan and the related Mortgage Loan,
the Master Servicer shall determine the allocation of such amounts in accordance with the related Intercreditor Agreement. All
amounts so allocable to any Trust Subordinate Companion Loan shall be held separate and apart from other amounts deposited in the
Collection Account (or in a subaccount of the Collection Account) and may be withdrawn from the Collection Account (pursuant to
Section 3.04 and otherwise) only to the extent set forth in this Agreement and not specifically prohibited under the related
Intercreditor Agreement.


 


(b)       The
Certificate Administrator, on behalf of the Trustee, shall establish and maintain (i) the Lower-Tier REMIC Distribution Account,

such Loss of Value Payments. Each account that constitutes the Loss of Value Reserve Fund shall be an Eligible Account or a sub-account
of an Eligible Account. The Special Servicer shall, upon receipt, deposit in the Loss of Value Reserve Fund all Loss of Value Payments
received by it. The Certificate Administrator shall, based upon information obtained from the CREFC® reports delivered
by the Master Servicer pursuant to the terms hereof, account for the Loss of Value Reserve Fund as an outside reserve fund within

Section 3.06     Investment
of Funds in the Collection Account and the REO Account.   (a) The Master Servicer (or, in the case of a Servicing
Account maintained by or for it, the Special Servicer) may direct any depository institution maintaining the Collection Account,
the Companion Distribution Account, or any Servicing Account (for purposes of this Section 3.06, an “Investment
Account”), the Special Servicer may direct any depository institution maintaining the REO Account or Loss of Value Reserve
Fund (also for purposes of this Section 3.06, an “Investment Account”) to invest or if it is such depository
institution, may itself invest, the funds held therein, only in one or more Permitted Investments bearing interest or sold at
a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the next succeeding
date on which funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the depository
institution maintaining such account is the obligor thereon and (ii) no later than the date on which funds are required to be
withdrawn from such account pursuant to this Agreement, if the depository institution maintaining such account is the obligor
thereon. All such Permitted Investments shall be held to maturity, unless payable on demand. Any funds held in an Investment Account
shall be held in the name of the Master Servicer or the Special Servicer, as applicable, on behalf of the Trustee (in its capacity
as such) for the benefit of the Certificateholders. The Master Servicer (in the case of the Collection Account, the Companion
Distribution Account or any Servicing Account maintained by or for the Master Servicer), the Special Servicer (in the case of
the REO Account, Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) on behalf of the
Trustee, shall maintain continuous physical possession of any Permitted Investment of amounts in the Collection Account, the Companion
Distribution Account, the Servicing Accounts, the Loss of Value Reserve Fund or the REO Account, as applicable, that is either
(i) a “certificated security,” as such term is defined in the UCC (such that the Trustee shall have control pursuant
to Section 8-106 of the UCC) or (ii) other property in


 



     -246-


     


    

 


which a secured party may perfect its security interest by physical possession
under the UCC or any other applicable law. In the case of any Permitted Investment held in the form of a “security entitlement”
(within the meaning of Section 8-102(a)(17) of the UCC), the Master Servicer or the Special Servicer, as applicable, shall take
or cause to be taken such action as the Trustee deems reasonably necessary to cause the Trustee to have control over such security
entitlement. In the event amounts on deposit in an Investment Account are at any time invested in a Permitted Investment payable
on demand, the Master Servicer (in the case of the Collection Account, the Companion Distribution Account or any Servicing Account
maintained by or for the Master Servicer) or the Special Servicer (in the case of the REO Account or any Servicing Account maintained
by or for the Special Servicer) shall:


 


(i)          consistent
with any notice required to be given thereunder, demand that payment thereon be made on the last day such Permitted Investment
may otherwise mature hereunder in an amount equal to the lesser of (a) all amounts then payable thereunder and (b) the amount required
to be withdrawn on such date; and


 


(ii)         demand
payment of all amounts due thereunder promptly upon determination by the Master Servicer, the Special Servicer, the Certificate
Administrator or the Trustee, as the case may be, that such Permitted Investment would not constitute a Permitted Investment in
respect of funds thereafter on deposit in the Investment Account.


 


(b)         Interest
and investment income realized on funds deposited in the Collection Account, the Companion Distribution Account or any Servicing
Account maintained by or for the Master Servicer to the extent of the Net Investment Earnings, if any, with respect to such account
for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the current
Distribution Date, shall be for the sole and exclusive benefit of the Master Servicer to the extent (with respect to Servicing
Accounts) not required to be paid to the related Mortgagor and shall be subject to its withdrawal, or withdrawal at its direction,
in accordance with Section 3.03 or Section 3.05(a), as the case may be. Interest and investment income realized on
funds deposited in the REO Account, Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer,
to the extent of the Net Investment Earnings, if any, with respect to such account for each period from and including any Distribution
Date to and including the immediately succeeding P&I Advance Date, shall be for the sole and exclusive benefit of the Special
Servicer and shall be subject to its withdrawal in accordance with Section 3.14(c). In the event that any loss shall be
incurred in respect of any Permitted Investment (as to which the Master Servicer or the Special Servicer, as applicable, would
have been entitled to any Net Investment Earnings hereunder) directed to be made by the Master Servicer or the Special Servicer,
as applicable, and on deposit in any of the Collection Account, the Companion Distribution Account, the Servicing Account, Loss
of Value Reserve Fund or the REO Account, the Master Servicer (in the case of the Collection Account, the Companion Distribution
Account or any Servicing Account maintained by or for the Master Servicer), the Special Servicer (in the case of the REO Account,
Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) shall deposit therein, no later
than the P&I Advance Date, without right of reimbursement, the amount of Net Investment Loss, if any, with respect to such
account for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the
current Distribution Date; provided that neither the Master Servicer nor the Special Servicer shall be required to deposit
any loss on an


 



     -247-


     


    

 


investment of funds in an Investment Account if such loss is incurred solely as a result of the insolvency of the
federal or state chartered depository institution or trust company that holds such Investment Account, so long as such depository
institution or trust company satisfied the qualifications set forth in the definition of Eligible Account at the time such investment
was made (and, with respect to the Master Servicer or the Special Servicer, such federal or state chartered depository institution
or trust company is not an Affiliate of the Master Servicer or the Special Servicer, as applicable, unless such depository institution
or trust company satisfied the qualification set forth in the definition of Eligible Account both (x) at the time the investment
was made and (y) thirty (30) days prior to such insolvency).


 


(c)         Except
as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment,
or if a default occurs in any other performance required under any Permitted Investment, the Master Servicer may and, upon the
request of Holders of Certificates entitled to a majority of the Voting Rights allocated to any Class shall, take such action as
may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings.


 


Section 3.07     Maintenance
of Insurance Policies; Errors and Omissions and Fidelity Coverage.   (a) To the extent permitted by the related
Mortgage Loan documents and required by the Servicing Standard, the Master Servicer (with respect to the Mortgage Loans (other
than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan) shall use efforts consistent with the Servicing Standard
to cause the Mortgagor to maintain (other than with respect to a Non-Serviced Mortgage Loan), and the Special Servicer (with respect
to REO Properties other than any Non-Serviced Mortgaged Properties) shall maintain all insurance coverage as is required under
the related Mortgage Loan documents except to the extent that the failure of the related Mortgagor to do so is an Acceptable Insurance
Default (and except as provided in the next sentence with respect to the Master Servicer or the Special Servicer, as applicable).
If the Mortgagor does not so maintain such insurance coverage, subject to its recoverability determination with respect to any
required Servicing Advance, the Master Servicer (with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan)
and any related Serviced Companion Loan) or the Special Servicer (with respect to REO Properties other than a Non-Serviced Mortgaged
Property) shall maintain all insurance coverage as is required under, and such insurance coverage is to be obtained from an insurer
meeting the requirements under, the related Mortgage Loan documents, but only in the event the Trustee has an insurable interest
therein and such insurance is available to the Master Servicer or the Special Servicer and, if available, can be obtained at commercially
reasonable rates. Any determination that such insurance coverage is not available or not available at commercially reasonable
rates shall be made with the consent of the Directing Holder (prior to the occurrence and continuance of any Control Termination
Event) and, after consultation by the Special Servicer with the Risk Retention Consultation Party pursuant to Section 6.08(a)
(in the case of the Directing Holder and Risk Retention Consultation Party, other than with respect to any Excluded Loan as
to such party). Such determination shall be made by the Master Servicer (with respect to the Mortgage Loans (other than a Non-Serviced
Mortgage Loan) and any related Serviced Companion Loan) or the Special Servicer (with respect to REO Properties other than any
Non-Serviced Mortgaged Property) except to the extent that the failure of the related Mortgagor to do so is an Acceptable Insurance
Default as determined by the Special Servicer; provided, however, that if any Mortgage permits the holder thereof
to dictate to the Mortgagor the insurance coverage to be


 



     -248-


     


    

 


maintained on such Mortgaged Property, the Master Servicer or, with respect
to an REO Property, the Special Servicer, as applicable, shall impose or maintain, as applicable, such insurance requirements
as are consistent with the Servicing Standard taking into account the insurance in place at the closing of the Mortgage Loan or
Trust Subordinate Companion Loan, provided that if any Mortgage Loan documents permit the holder thereof to dictate to
the Mortgagor the insurance coverage to be maintained on such Mortgaged Property, the Master Servicer or, with respect to a REO
Property, the Special Servicer will impose or maintain such insurance requirements as are consistent with the Servicing Standard
taking into account the insurance in place at the origination of the Mortgage Loan or Trust Subordinate Companion Loan; provided,
further, that, with respect to the immediately preceding proviso, the Master Servicer shall be obligated to use efforts
consistent with the Servicing Standard to cause the Mortgagor to maintain (or to itself maintain) insurance against property damage
resulting from terrorist or similar acts unless the Mortgagor’s failure is an Acceptable Insurance Default (as determined
by the Special Servicer with the consent of the Directing Holder (unless a Control Termination Event has occurred) and after consultation
by the Special Servicer with the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case, other than
with respect to any Excluded Loan as to such party) and only in the event the Trustee has an insurable interest therein and such
insurance is available to the Master Servicer or the Special Servicer, as the case may be, and, if available, can be obtained
at commercially reasonable rates. The Master Servicer and the Special Servicer shall be entitled to rely on insurance consultants
(at the applicable servicer’s expense) in determining whether any insurance is available at commercially reasonable rates.
Subject to Section 3.15(a) and the costs of such insurance being reimbursed or paid to the Special Servicer as provided
in the third-to-last sentence of this paragraph, the Special Servicer shall maintain (except to the extent that the failure to
maintain such insurance coverage is an Acceptable Insurance Default) for each REO Property (other than any Non-Serviced Mortgaged
Property) no less insurance coverage than was previously required of the Mortgagor under the related Mortgage Loan documents unless
the Special Servicer determines with the consent of the Directing Holder (prior to the occurrence and continuance of a Control
Termination Event) and after consultation by the Special Servicer with the Risk Retention Consultation Party pursuant to Section
6.08(a) (in each case, other than with respect to a Mortgage Loan that is an Excluded Loan as to such party) that such insurance
is not available at commercially reasonable rates or that the Trustee does not have an insurable interest, in which case the Master
Servicer shall be entitled to conclusively rely on the Special Servicer’s determination. All Insurance Policies maintained
by the Master Servicer or the Special Servicer shall (i) contain a “standard” mortgagee clause, with loss payable
to the Master Servicer on behalf of the Trustee (in the case of insurance maintained in respect of Mortgage Loans (other than
any Non-Serviced Mortgage Loan), including any related Serviced Companion Loan, other than REO Properties) or to the Special Servicer
on behalf of the Trustee (in the case of insurance maintained in respect of REO Properties), (ii) be in the name of the Trustee
(in the case of insurance maintained in respect of REO Properties), (iii) include coverage in an amount not less than the lesser
of (x) the full replacement cost of the improvements securing Mortgaged Property or the REO Property, as applicable, and (y) the
outstanding principal balance owing on the related Mortgage Loan (including any related Serviced Companion Loan) or REO Loan,
as applicable, and in any event, the amount necessary to avoid the operation of any co-insurance provisions, (iv) include a replacement
cost endorsement providing no deduction for depreciation (unless such endorsement is not permitted under the related Mortgage
Loan documents), (v) be


 



     -249-


     


    

 


noncancelable without thirty (30) days prior written notice to the insured party (except in the case of
nonpayment, in which case such policy shall not be cancelled without ten (10) days prior notice) and (vi) subject to the first
proviso in the second sentence of this Section 3.07(a), be issued by a Qualified Insurer authorized under applicable law
to issue such Insurance Policies. Any amounts collected by the Master Servicer or the Special Servicer under any such Insurance
Policies (other than amounts to be applied to the restoration or repair of the related Mortgaged Property or REO Property or amounts
to be released to the related Mortgagor, in each case in accordance with the Servicing Standard and the provisions of the related
Mortgage Loan documents) shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.05(a).
Any costs incurred by the Master Servicer in maintaining any such Insurance Policies in respect of Mortgage Loans (including any
related Serviced Companion Loan) (other than REO Properties and other than any Non-Serviced Mortgage Loan) (i) if the Mortgagor
defaults on its obligation to do so, shall be advanced by the Master Servicer as a Servicing Advance (so long as such Advance
would not be a Nonrecoverable Advance and if such Advance would be a Nonrecoverable Advance then such cost shall instead be paid
out of the Collection Account) and will be charged to the related Mortgagor and (ii) shall not, for purposes of calculating monthly
distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan and Serviced Companion
Loan (if any), notwithstanding that the terms of such Mortgage Loan or Serviced Companion Loan so permit. Any cost incurred by
the Special Servicer in maintaining any such Insurance Policies with respect to REO Properties shall be an expense of the Trust
payable out of the related REO Account pursuant to Section 3.14(c) or, if the amount on deposit therein is insufficient
therefor, advanced by the Master Servicer as a Servicing Advance (so long as such Advance would not be a Nonrecoverable Advance
and if such Advance would be a Nonrecoverable Advance then such cost shall instead be paid out of the Collection Account). The
foregoing provisions of this Section 3.07 shall apply to any Serviced Whole Loan as if it were a single “Mortgage
Loan”. Notwithstanding any provision to the contrary, the Master Servicer shall not be required to maintain, and shall not
be in default for failing to obtain, any earthquake or environmental insurance on any Mortgaged Property unless such insurance
was required at the time of origination of the related Mortgage Loan and is currently available at commercially reasonable rates.


 


Notwithstanding the foregoing,
with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that either
(x) require the Mortgagor to maintain “all risk” property insurance (and do not expressly permit an exclusion for terrorism)
or (y) contain provisions generally requiring the applicable Mortgagor to maintain insurance in types and against such risks as
the holder of such Mortgage Loan (including any related Serviced Companion Loan) reasonably requires from time to time in order
to protect its interests, the Master Servicer shall be consistent with the Servicing Standard, (A) monitor in accordance with the
Servicing Standard whether the insurance policies for the related Mortgaged Property contain Additional Exclusions (provided
that the Master Servicer will be entitled to conclusively rely upon the certificates of insurance in determining whether such policies
contain Additional Exclusions), (B) request the Mortgagor to either purchase insurance against the risks specified in the Additional
Exclusions or provide an explanation as to its reasons for failing to purchase such insurance and (C) notify the Special Servicer
if it has knowledge that any insurance policy contains Additional Exclusions or if it has knowledge (such knowledge to be based
upon the Master Servicer’s compliance with the immediately preceding


 



     -250-


     


    

  


clauses (A) and (B) above) that any Mortgagor
fails to purchase the insurance requested to be purchased by the Master Servicer pursuant to clause (B) above. If the Special
Servicer determines in accordance with the Servicing Standard that such failure is not an Acceptable Insurance Default, the Special
Servicer shall notify the Master Servicer and the Master Servicer shall use efforts consistent with the Servicing Standard to cause
such insurance to be maintained. The Special Servicer (at the expense of the Trust) shall be entitled to rely on insurance consultants
in making such determinations. The Master Servicer shall be entitled to rely on insurance consultants (at the expense of such Master
Servicer) in determining whether Additional Exclusions exist. Furthermore, the Special Servicer shall promptly deliver such conclusions
in writing to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website for those Mortgage Loans
that (i) have one of the ten (10) highest outstanding Stated Principal Balances of all of the Mortgage Loans then included in the
Trust or (ii) comprise more than 5% of the outstanding Stated Principal Balance of the Mortgage Loans then included in the Trust.
During the period that the Special Servicer is evaluating the availability of such insurance or waiting for a response from the
Directing Holder, or with respect to a Serviced AB Whole Loan, the holder of the related Subordinate Companion Loan, or to consult
with the Risk Retention Consultation Party pursuant to Section 6.08(a), neither the Master Servicer nor the Special Servicer
will be liable for any loss related to its failure to require the Mortgagor to maintain (or its failure to maintain) such insurance
and shall not be in default of its obligations as a result of such failure unless the Master Servicer or the Special Servicer is
required to take any immediate action pursuant to the Servicing Standard or other servicing requirements of this Agreement and
the Master Servicer will not itself maintain such insurance or cause such insurance to be maintained.


 


(b)         (i)
If the Master Servicer or the Special Servicer shall obtain and maintain a blanket Insurance Policy with a Qualified Insurer insuring
against fire and hazard losses on all of the Mortgage Loans (including any related Serviced Companion Loan, but excluding any Non-Serviced
Mortgage Loan) or REO Properties (other than with respect to a Non-Serviced Mortgaged Property), as the case may be, required to
be serviced and administered hereunder, then, to the extent such Insurance Policy provides protection equivalent to the individual
policies otherwise required, the Master Servicer or the Special Servicer shall conclusively be deemed to have satisfied its obligation
to cause fire and hazard insurance to be maintained on the related Mortgaged Properties or REO Properties. Such Insurance Policy
may contain a deductible clause, in which case the Master Servicer or the Special Servicer shall, if there shall not have been
maintained on the related Mortgaged Property or REO Property a fire and hazard Insurance Policy complying with the requirements
of Section 3.07(a), and there shall have been one or more losses which would have been covered by such Insurance Policy,
promptly deposit into the Collection Account from its own funds the amount of such loss or losses that would have been covered
under the individual policy but are not covered under the blanket Insurance Policy because of such deductible clause to the extent
that any such deductible exceeds the deductible limitation that pertained to the related Mortgage Loan (including any related Serviced
Companion Loan), or in the absence of such deductible limitation, the deductible limitation which is consistent with the Servicing
Standard. In connection with its activities as administrator and Master Servicer of the Mortgage Loans or any Serviced Companion
Loans, the Master Servicer agrees to prepare and present, on behalf of itself, the Trustee and Certificateholders, claims under
any such blanket Insurance Policy in a timely fashion in accordance with the terms of such policy. Consistent with subsection
(a) above, the Special Servicer, to the extent


 



     -251-


     


    

 


consistent with the Servicing Standard, may maintain, earthquake insurance on
REO Properties (other than with respect to a Non-Serviced Mortgaged Property), provided coverage is available at commercially reasonable
rates, the cost of which shall be a Servicing Advance.


 


(ii)         If
the Master Servicer or the Special Servicer shall cause any Mortgaged Property or REO Property to be covered by a master single
interest or force-placed insurance policy with a Qualified Insurer naming the Master Servicer or the Special Servicer on behalf
of the Trustee as the loss payee, then to the extent such Insurance Policy provides protection equivalent to the individual policies
otherwise required, the Master Servicer or the Special Servicer shall conclusively be deemed to have satisfied its obligation to
cause such insurance to be maintained on the related Mortgaged Properties and REO Properties. In the event the Master Servicer
or the Special Servicer shall cause any Mortgaged Property or REO Property to be covered by such master single interest or force-placed
insurance policy, the incremental costs of such insurance applicable to such Mortgaged Property or REO Property (i.e., other than
any minimum or standby premium payable for such policy whether or not any Mortgaged Property or REO Property is covered thereby)
shall be paid by the Master Servicer as a Servicing Advance. Such master single interest or force-placed policy may contain a deductible
clause, in which case the Master Servicer or the Special Servicer shall, in the event that there shall not have been maintained
on the related Mortgaged Property or REO Property a policy otherwise complying with the provisions of Section 3.07(a), and
there shall have been one or more losses which would have been covered by such policy had it been maintained, deposit into the
Collection Account from its own funds the amount not otherwise payable under the master single or force-placed interest policy
because of such deductible clause, to the extent that any such deductible exceeds the deductible limitation that pertained to the
related Mortgage Loan, including any related Serviced Companion Loan, or, in the absence of any such deductible limitation, the
deductible limitation which is consistent with the Servicing Standard.


 


(c)         Each
of the Master Servicer and the Special Servicer shall obtain and maintain at its own expense and keep in full force and effect
throughout the term of this Agreement a blanket fidelity bond and an errors and omissions insurance policy with a Qualified Insurer
covering the Master Servicer’s and the Special Servicer’s, as applicable, officers and employees acting on behalf of
the Master Servicer and the Special Servicer in connection with its activities under this Agreement. Notwithstanding the foregoing,
so long as the long-term debt or the deposit obligations or claims-paying ability of the Master Servicer (or its immediate or remote
parent) or the Special Servicer (or its immediate or remote parent), as applicable, is rated at least “A3” by Moody’s,
“A(low)” by DBRS (if rated by DBRS) and “A-” by Fitch (if rated by Fitch), the Master Servicer (or its
public parent) or the Special Servicer (or its public parent), as applicable, shall be allowed to provide self-insurance with respect
to a fidelity bond and an “errors and omissions” Insurance Policy. Such amount of coverage shall be in such form and
amount as are consistent with the Servicing Standard. Coverage of the Master Servicer or the Special Servicer under a policy or
bond obtained by an Affiliate of the Master Servicer or the Special Servicer and providing the coverage required by this Section
3.07(c) shall satisfy the requirements of this Section 3.07(c). The Special Servicer and the Master Servicer will promptly
report in writing to the Trustee any material changes that may occur in their respective fidelity bonds, if any, and/or their respective
errors and omissions insurance policies, as the case may be,


 



     -252-


     


    

 


and will furnish to the Trustee evidence that such bonds, if any,
and insurance policies are in full force and effect.


 


(d)         At
the time the Master Servicer determines in accordance with the Servicing Standard that any Mortgaged Property (other than a Non-Serviced
Mortgaged Property) is in a federally designated special flood hazard area (and such flood insurance has been made available),
the Master Servicer will use efforts consistent with the Servicing Standard to cause the related Mortgagor (in accordance with
applicable law and the terms of the Mortgage Loan and related Serviced Companion Loan documents) to maintain, and, if the related
Mortgagor shall default in its obligation to so maintain, shall itself maintain to the extent available at commercially reasonable
rates (as determined by the Master Servicer in accordance with the Servicing Standard) and to the extent the Trustee, as mortgagee,
has an insurable interest therein, flood insurance in respect thereof. Such flood insurance shall be in an amount equal to the
lesser of (i) the unpaid principal balance of the related Mortgage Loan (and any related Serviced Companion Loan, if applicable),
and (ii) the maximum amount of insurance which is available under the National Flood Insurance Act of 1968, as amended, plus such
additional excess flood coverage with respect to the Mortgaged Property, if any, in an amount consistent with the Servicing Standard,
but only to the extent the related Mortgage Loan (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan permits
the mortgagee to require such coverage and the maintenance of such coverage is consistent with the Servicing Standard. If the cost
of any insurance described above is not borne by the Mortgagor, the Master Servicer shall promptly make a Servicing Advance for
such costs.


 


(e)         During
all such times as any REO Property (other than with respect to a Non Serviced Mortgaged Property) shall be located in a federally
designated special flood hazard area, the Special Servicer will cause to be maintained, to the extent available at commercially
reasonable rates (as determined by the Special Servicer (with the consent of the Directing Holder (prior to the occurrence and
continuance of a Control Termination Event) and in consultation with the Risk Retention Consultation Party pursuant to Section
6.08(a) (in either such case, other than with respect to any Mortgage Loan that is an Excluded Loan as to such party)) in accordance
with the Servicing Standard), a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance
Administration in an amount representing coverage not less than the maximum amount of insurance which is available under the National
Flood Insurance Act of 1968, as amended. The cost of any such flood insurance with respect to an REO Property shall be an expense
of the Trust payable out of the related REO Account pursuant to Section 3.14(c) or, if the amount on deposit therein is
insufficient therefor, paid by the Master Servicer as a Servicing Advance.


 


(f)          Each
of the Operating Advisor and Asset Representations Reviewer shall obtain and maintain at its own expense and keep in full force
and effect throughout the term of this Agreement an “errors and omissions” insurance policy with a Qualified Insurer
covering losses that may be sustained as a result of an officer’s or employee’s errors or omissions.


 


Section 3.08     Enforcement
of Due-on-Sale Clauses; Assumption Agreements.   (a) As to each Mortgage Loan (other than a Non-Serviced Mortgage
Loan) and any related Serviced Companion Loan that contains a provision in the nature of a “due-on-sale” clause, which
by its terms:


 






     -253-


     


    

 


(i)          provides
that such Mortgage Loan and any related Companion Loan shall (or may at the mortgagee’s option) become due and payable upon
the sale or other transfer of an interest in the related Mortgaged Property or equity interests in the Mortgagor or principals
of the Mortgagor; or


 


(ii)         provides
that such Mortgage Loan and any related Companion Loan may not be assumed without the consent of the mortgagee in connection with
any such sale or other transfer,


 


then, for so long as
such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement, the Special Servicer, on behalf of
the Trustee as the mortgagee of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or related
Companion Loan (x) to accelerate the payments thereon or (y) to withhold its consent to any sale or transfer, consistent with the
Servicing Standard or (b) waive any right to exercise such rights, provided that, with respect to all Specially Serviced
Loans and Non-Specially Serviced Loans, the Special Servicer has obtained, prior to the occurrence and continuance of a Control
Termination Event and other than with respect to an Excluded Loan as to such party, the prior written consent (or deemed consent)
of the Directing Holder (or (i) after the occurrence and during the continuance of a Control Termination Event, but prior to a
Consultation Termination Event and (ii) other than with respect to any Excluded Loan as to such party, upon consultation with the
Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08(a) hereof), which consent, if required,
shall be deemed given ten (10) Business Days after receipt (unless earlier objected to by the Directing Holder) of the Special
Servicer’s written analysis and recommendation with respect to such waiver together with such other information in the Special
Servicer’s possession that is reasonably requested by the Directing Holder, and (iii) with respect to any Mortgage Loan (w)
with a Stated Principal Balance greater than $35,000,000, (x) with a Stated Principal Balance greater than or equal to 5% of the
aggregated Stated Principal Balance of the Mortgage Loans then outstanding, (y) together with all other Mortgage Loans with which
it is cross-collateralized or cross-defaulted or together with all other Mortgage Loans with the same Mortgagor (or an affiliate
thereof), that is one of the ten largest Mortgage Loans outstanding (by Stated Principal Balance), or (z) that is the Yorkshire
& Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, the Master Servicer or the Special Servicer, as the
case may be, prior to consenting to any action, shall obtain, a Rating Agency Confirmation from each Rating Agency and a confirmation
of any applicable rating agency that such action will not result in the downgrade, withdrawal or qualification of its then-current
ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be
considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
pursuant to Section 3.25), provided, however, that with respect to subclauses (x) and (y) of
this subclause (iii), such Mortgage Loan shall also have a Stated Principal Balance of at least $10,000,000 for such Rating
Agency Confirmation requirement to apply. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with
respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the
Controlling Class (regardless of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer
shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed
Major Decisions that it is processing or for which its consent is required and consider alternative


 



     -254-


     


    

 


actions recommended by the
Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting with the
Operating Advisor.


 


In connection with any
request for a Rating Agency Confirmation from a Rating Agency (or, with respect to any Serviced Companion Loan Securities, the
related rating agencies) pursuant to this Section 3.08(a), the Special Servicer shall (if not already provided in accordance
with Section 3.25 of this Agreement) deliver a Review Package to the 17g-5 Information Provider (or, with respect to any
Serviced Companion Loan Securities, the related 17g-5 information provider) in accordance with Section 3.25 of this Agreement.


 


If any Mortgage Loan
(other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan provides that such Mortgage Loan or related Serviced
Companion Loan may be assumed or transferred without the consent of the mortgagee provided that certain conditions are satisfied,
then for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement, the Special Servicer,
with respect to all Specially Serviced Loans (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loans, on
behalf of the Trustee as the mortgagee of record, shall determine in accordance with the Servicing Standard whether such conditions
have been satisfied or, with respect to any Mortgage Loan which does not allow the mortgagee discretion in approving a transfer
or assumption or does not allow for discretion in determining whether conditions to a transfer or assumption have been satisfied,
the Master Servicer, on behalf of the Trustee as mortgagee of record, shall make such determination with respect to whether such
conditions have been satisfied.


 


(b)         As
to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that contains a provision
in the nature of a “due-on-encumbrance” clause that by its terms:


 


(i)          provides
that such Mortgage Loan and any related Companion Loan shall (or may at the mortgagee’s option) become due and payable upon
the creation of any additional lien or other encumbrance on the related Mortgaged Property or equity interests in the Mortgagor
or principals of the Mortgagor; or


 


(ii)         requires
the consent of the mortgagee to the creation of any such additional lien or other encumbrance on the related Mortgaged Property
or equity interests in the Mortgagor or principals of the Mortgagor;


 


then, for so long as
such Mortgage Loan (and related Companion Loan, if applicable) is serviced under this Agreement, the Special Servicer, on behalf
of the Trustee as the mortgagee of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or related
Companion Loan (x) to accelerate the payments thereon or (y) to withhold its consent to the creation of any additional lien or
other encumbrance, consistent with the Servicing Standard or (b) waive its right to exercise such rights, provided that
with respect to all Specially Serviced Loans and Non-Specially Serviced Loans, prior to the occurrence and continuance of a Control
Termination Event and other than with respect to an Excluded Loan as to such party, the Special Servicer has obtained the consent
of the Directing Holder (or (i) after the occurrence and during the continuance of a Control Termination Event, but prior to a
Consultation Termination


 



     -255-


     


    

 


Event and (ii) other than with respect to any Excluded Loan as to such party, upon consultation with the
Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08(a) hereof), which consent, if required,
shall be deemed given ten (10) Business Days after receipt by the Directing Holder of the Special Servicer’s written analysis
and recommendation with respect to such waiver or exercise of such rights together with such other information in the Special Servicer’s
possession that is reasonably requested by the Directing Holder, and the Special Servicer has obtained Rating Agency Confirmation
from each Rating Agency and a confirmation of any applicable rating agency that such action will not result in the downgrade, withdrawal
or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25) if such Mortgage Loan (A) has an outstanding principal
balance that is greater than or equal to 2% of the Stated Principal Balance of the outstanding Mortgage Loans, (B) has an LTV Ratio
greater than 85% (including any existing and proposed debt), (C) has a Debt Service Coverage Ratio less than 1.20x (in each case,
determined based upon the aggregate of the Stated Principal Balance of the Mortgage Loan and related Companion Loan, if any, and
the principal amount of the proposed additional lien), (D) is the Yorkshire & Lexington Towers Whole Loan or The Standard Highline
NYC Whole Loan, (E) is one of the ten largest Mortgage Loans (by Stated Principal Balance) or (F) has a Stated Principal Balance
greater than $20,000,000; provided, however, that with respect to subclauses (A), (B), (C) and
(E) of this subclause (iii), such Mortgage Loan shall also have a Stated Principal Balance of at least $10,000,000
for such Rating Agency Confirmation requirement to apply. Notwithstanding anything herein to the contrary, with respect to any
Excluded Loan (regardless of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer
shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed
Major Decisions and consider alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with the
procedures set forth in Section 6.08 for consulting with the Operating Advisor.


 


In connection with any
request for a Rating Agency Confirmation from a Rating Agency (or, with respect to any Serviced Companion Loan Securities, the
related rating agencies) pursuant to this Section 3.08(b), the Special Servicer shall (if not already provided in accordance
with Section 3.25 of this Agreement) deliver a Review Package to the 17g-5 Information Provider (or, with respect to any
Serviced Companion Loan Securities, the related 17g-5 information provider) in accordance with Section 3.25 of this Agreement.


 


To the extent permitted
by the related Mortgage Loan documents, the Rating Agency Confirmation described in the immediately preceding paragraph or in Section
3.08(a) shall be an expense of the related Mortgagor; provided that if the Mortgage Loan documents are silent as to
who bears the costs of obtaining any such Rating Agency Confirmation, the Special Servicer shall use reasonable efforts to make
the related Mortgagor bear such costs and expenses. Unless determined to be a Nonrecoverable Advance such costs not collected from
the related Mortgagor shall be advanced as a Servicing Advance.


 


If any Mortgage Loan
or related Companion Loan provides that such Mortgage Loan or related Companion Loan may be further encumbered without the consent
of the mortgagee provided that certain conditions are satisfied and there is no lender discretion with


 



     -256-


     


    

 


respect to the satisfaction
of such conditions, then for so long as such Mortgage Loan or related Companion Loan is being serviced under this Agreement, the
Special Servicer, with respect to all Specially Serviced Loans (other than a Non-Serviced Mortgage Loan) or related Serviced Companion
Loans, on behalf of the Trustee as the mortgagee of record, shall determine in accordance with the Servicing Standard whether such
conditions have been satisfied or, with respect to any Mortgage Loan which does not allow the mortgagee discretion in approving
a further encumbrance or does not allow for discretion in determining whether conditions to a further encumbrance have been satisfied,
the Master Servicer, on behalf of the Trustee as mortgagee of record, shall make such determination with respect to whether such
conditions have been satisfied.


 


(c)         Nothing
in this Section 3.08 shall constitute a waiver of the Trustee’s right, as the mortgagee of record, to receive notice
of any assumption of a Mortgage Loan, any sale or other transfer of the related Mortgaged Property or the creation of any additional
lien or other encumbrance with respect to such Mortgaged Property.


 


(d)         Except
as otherwise permitted by Section 3.08(a) and (b) and/or Section 3.18, neither the Master Servicer nor the
Special Servicer shall agree to modify, waive or amend any term of any Mortgage Loan and related Serviced Companion Loan, as applicable,
in connection with the taking of, or the failure to take, any action pursuant to this Section 3.08. The Master Servicer
and the Special Servicer, as applicable, shall provide copies of any final waivers (except with respect to provision of any such
waivers to the 17g-5 Information Provider, exclusive of any Privileged Information) it effects pursuant to Section 3.08(a)
or (b) to each other and to the 17g-5 Information Provider with respect to each Mortgage Loan, and shall notify the Trustee,
the Certificate Administrator, each other and, subject to the terms of this Agreement, the 17g-5 Information Provider (for posting
to the 17g-5 Information Provider’s Website in accordance with Section 3.25) and, with respect to a Whole Loan, the
related Serviced Companion Noteholder, of any assumption or substitution agreement executed pursuant to Section 3.08(a)
or (b) and shall forward thereto a copy of such agreement.


 


(e)         Notwithstanding
any other provision of this Agreement, the Special Servicer may not waive its rights or grant its consent under any “due-on-sale”
or “due-on-encumbrance” clause relating to any Mortgage Loan (other than any Non-Serviced Mortgage Loan) and any related
Serviced Companion Loan without (A) the consent of the Directing Holder (prior to the occurrence and continuance of a Control Termination
Event), (B) after the occurrence and during the continuance of a Control Termination Event, but prior to the occurrence and continuance
a Consultation Termination Event, consultation with the Directing Holder and (C) with respect to a Specially Serviced Loan, consultation
with the Risk Retention Consultation Party pursuant to Section 6.08. The Directing Holder shall have ten (10) Business Days
after receipt of notice along with the Special Servicer’s written recommendation and analysis with respect to such proposed
waiver or proposed granting of consent and any additional information the Directing Holder may reasonably request from the Special
Servicer and reasonably available to the Special Servicer with respect to such proposed waiver or consent under any “due
on sale” or “due-on-encumbrance” clause in which to grant or withhold its consent (provided that if the
Special Servicer fails to receive a response to such notice from the Directing Holder in writing within such period, then the Directing
Holder shall be deemed to have consented to such proposed waiver or consent).


 






     -257-


     


    

 


(f)          Notwithstanding
the foregoing provisions of this Section 3.08, if the Master Servicer (with respect to Non-Specially Serviced Loans) or
the Special Servicer (with respect to Specially Serviced Loans) makes a determination under Sections 3.08(a) or 3.08(b)
hereof that the applicable conditions in the related Mortgage Loan or Companion Loan documents, as applicable, with respect to
assumptions or encumbrances permitted without the consent of the mortgagee have been satisfied, the applicable assumptions and
transfers may be subject to an assumption or other fee, unless such fees are otherwise prohibited pursuant to the Mortgage Loan
documents; provided that any such fee not provided for in the Mortgage Loan documents does not constitute a “significant”
change in yield pursuant to Treasury Regulations Section 1.1001-3(e)(2).


 


(g)         Notwithstanding
any other provision of this Section 3.08, without any other approval or consent, the Master Servicer (for Mortgage Loans
and Serviced Whole Loans other than Specially Serviced Loans) may grant and process a Mortgagor’s request for (i) consent
to subject the related Mortgaged Property to an immaterial easement, a right of way or similar agreement for utilities, access,
parking, public improvements or another purpose, (ii) consent to subordination of the related Mortgage Loan or Serviced Whole Loan
to such easement, right of way or similar agreement and (iii) consent to any other matter that is not a Major Decision; provided
that the Master Servicer (a) shall have determined in accordance with the Servicing Standard that such easement, right of way or
similar agreement or other matter will not materially and adversely affect the operation or value of such Mortgaged Property or
the Trust Fund’s interest in the Mortgaged Property and (b) shall have determined that such easement, right of way or similar
agreement or other matter will not cause any Trust REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding.
The Master Servicer may rely on an Opinion of Counsel in making any such determination under clause (b) above.


 


Section 3.09     Realization
Upon Defaulted Loans and Companion Loans.   (a) Upon an event of default under the Mortgage Loan documents
related to a Serviced Whole Loan or a Mortgage Loan with mezzanine debt, the Master Servicer shall promptly provide written notice
to the related Companion Holder or mezzanine lender, as applicable, with a copy of such notice to the Special Servicer. The Special
Servicer shall, subject to subsections (b) through (d) of this Section 3.09 and Section 3.24, subject
to the Directing Holder’s and the Risk Retention Consultation Party’s respective rights pursuant to Section 6.08,
and any Companion Holder or mezzanine lender’s rights under the related Intercreditor Agreement (in the case of a Serviced
Whole Loan, on behalf of the holders of the beneficial interest of the related Companion Loan) or this Agreement, exercise reasonable
efforts, consistent with the Servicing Standard, to foreclose upon or otherwise comparably convert (which may include an REO Acquisition)
the ownership of property securing any such Mortgage Loan (other than any Non-Serviced Mortgage Loan) and related Companion Loan,
if any, as come into and continue in default as to which no satisfactory arrangements (including by way of a discounted pay-off)
can be made for collection of delinquent payments, and which are not released from the Trust Fund pursuant to any other provision
hereof. The foregoing is subject to the provision that, in any case in which a Mortgaged Property shall have suffered damage from
an Uninsured Cause, the Master Servicer or the Special Servicer shall not be required to make a Servicing Advance and expend funds
toward the restoration of such property unless the Special Servicer has determined in its reasonable discretion that such restoration
will increase the net proceeds of liquidation of such Mortgaged Property to Certificateholders after reimbursement to the Master
Servicer for such


 



     -258-


     


    

 


Servicing Advance, and the Master Servicer or the Special Servicer has not determined that such Servicing Advance
together with accrued and unpaid interest thereon would constitute a Nonrecoverable Advance. The costs and expenses incurred by
the Special Servicer in any such proceedings shall be advanced by the Master Servicer; provided that, in each case, such
cost or expense would not, if incurred, constitute a Nonrecoverable Servicing Advance. Nothing contained in this Section 3.09
shall be construed so as to require the Master Servicer or the Special Servicer, on behalf of the Trust, to make an offer
on any Mortgaged Property at a foreclosure sale or similar proceeding that is in excess of the fair market value of such property,
as determined by the Master Servicer or the Special Servicer in its reasonable judgment taking into account the factors described
in Section 3.16(b) and the results of any Appraisal obtained pursuant to the following sentence, all such offers to be
made in a manner consistent with the Servicing Standard. If and when the Special Servicer or the Master Servicer deems it necessary
and prudent for purposes of establishing the fair market value of any Mortgaged Property securing a Defaulted Loan or any related
defaulted Companion Loan, whether for purposes of making an offer at foreclosure or otherwise, the Special Servicer or the Master
Servicer, as the case may be, is authorized to have an Appraisal performed with respect to such property by an Independent MAI-designated
appraiser the cost of which shall be paid by the Master Servicer as a Servicing Advance.


 


(b)         The
Special Servicer shall not acquire any personal property pursuant to this Section 3.09 unless either:


 


(i)          such
personal property is incident to real property (within the meaning of Section 856(e)(1) of the Code) so acquired by the Special
Servicer; or


 


(ii)         the
Special Servicer shall have obtained an Opinion of Counsel (the cost of which shall be paid by the Master Servicer as a Servicing
Advance) to the effect that the holding of such personal property by the Trust (to the extent not allocable to the related Companion
Loan) will not cause an Adverse REMIC Event.


 


(c)         Notwithstanding
the foregoing provisions of this Section 3.09 and Section 3.24, neither the Master Servicer nor the Special Servicer
shall, on behalf of the Trustee, obtain title to a Mortgaged Property in lieu of foreclosure or otherwise, or take any other action
with respect to any Mortgaged Property, if, as a result of any such action, the Trustee, on behalf of the Certificateholders, the
Holders of any Loan-Specific Certificates and/or any related Companion Holder, would be considered to hold title to, to be a “mortgagee-in-possession”
of, or to be an “owner” or “operator” of such Mortgaged Property within the meaning of CERCLA or any comparable
law, unless (as evidenced by an Officer’s Certificate to such effect delivered to the Trustee) the Special Servicer has previously
determined in accordance with the Servicing Standard, based on an Environmental Assessment of such Mortgaged Property performed
by an Independent Person who regularly conducts Environmental Assessments and performed within six (6) months prior to any such
acquisition of title or other action, that:


 


(i)          such
Mortgaged Property is in compliance with applicable environmental laws or, if not, after consultation with an environmental consultant,
that it would be in the best economic interest of the Certificateholders (and with respect to any Serviced Whole Loan, the related
Companion Holders), as a collective whole as if such Certificateholders


 



     -259-


     


    

 


and, if applicable, such Companion Holders constituted
a single lender, to take such actions as are necessary to bring such Mortgaged Property in compliance with such laws, and


 


(ii)         there
are no circumstances present at such Mortgaged Property relating to the use, management or disposal of any hazardous materials
for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any currently effective
federal, state or local law or regulation, or that, if any such hazardous materials are present for which such action could be
required, after consultation with an environmental consultant, it would be in the best economic interest of the Certificateholders
(and with respect to any Serviced Whole Loan, the Companion Holders), as a collective whole as if such Certificateholders and,
if applicable, such Companion Holders constituted a single lender, to take such actions with respect to the affected Mortgaged
Property.


 


The cost of any such
Environmental Assessment shall be paid by the Master Servicer as a Servicing Advance and the cost of any remedial, corrective or
other further action contemplated by clause (i) and/or clause (ii) of the preceding sentence shall be paid by the
Master Servicer as a Servicing Advance, unless it is a Nonrecoverable Servicing Advance (in which case it shall be an expense of
the Trust and, in the case of a Serviced Whole Loan, shall be withdrawn in accordance with the related Intercreditor Agreement
by the Master Servicer from the Collection Account, including from the Companion Distribution Account (such withdrawal to be made
from amounts on deposit therein that are otherwise payable on or allocable to such Serviced Whole Loan)); and if any such Environmental
Assessment so warrants, the Special Servicer shall, except with respect to any Companion Loan and any Environmental Assessment
ordered after such Mortgage Loan has been paid in full, perform such additional environmental testing at the expense of the Trust
as it deems necessary and prudent to determine whether the conditions described in clauses (i) and (ii) of the preceding
sentence have been satisfied. With respect to Non-Specially Serviced Loans, the Master Servicer and, with respect to Specially
Serviced Loans, the Special Servicer (other than any Non-Serviced Mortgage Loan) shall review and be familiar with the terms and
conditions relating to enforcing claims and shall monitor the dates by which any claim or action must be taken (including delivering
any notices to the insurer and using reasonable efforts to perform any actions required under such policy) under each environmental
insurance policy in effect and obtained on behalf of the mortgagee to receive the maximum proceeds available under such policy
for the benefit of the Certificateholders and the Trustee (as holder of the Lower-Tier Regular Interests).


 


(d)         If
(i) the environmental testing contemplated by subsection (c) above establishes that either of the conditions set forth in
clauses (i) and (ii) of subsection (c) above of the first sentence thereof has not been satisfied with respect
to any Mortgaged Property securing a Defaulted Loan and, in the case of a Serviced Mortgage Loan, any related Companion Loan, and
(ii) there has been no breach of any of the representations and warranties set forth in or required to be made pursuant to Section
6 of each of the Mortgage Loan Purchase Agreements for which the applicable Mortgage Loan Seller could be required to repurchase
such Defaulted Loan pursuant to Section 6 of the applicable Mortgage Loan Purchase Agreement, then the Special Servicer shall take
such action as it deems to be in the best economic interest of the Trust (other than proceeding to acquire title to the Mortgaged
Property) and is hereby authorized, with


 



     -260-


     


    

 


the consent of the Directing Holder and after consultation with the Risk Retention Consultation
Party pursuant to Section 6.08(a) (in each case, (A) prior to the occurrence and continuance of a Control Termination Event
(or with respect to any AB Mortgage Loan, after the occurrence and during the continuation of an AB Control Appraisal Period, but
prior to the occurrence and continuance of a Control Termination Event) and (B) other than with respect to any Excluded Loan as
to such party) at such time as it deems appropriate to release such Mortgaged Property from the lien of the related Mortgage, provided
that, if such Mortgage Loan has a then-outstanding principal balance of greater than $1,000,000, then prior to the release of the
related Mortgaged Property from the lien of the related Mortgage, (i) the Special Servicer shall have notified the Rating Agencies,
the Trustee, the Certificate Administrator, the Master Servicer, the Directing Holder and the Risk Retention Consultation Party
(in the case of the Directing Holder, prior to the occurrence and continuance of a Consultation Termination Event, and in the case
of the Directing Holder or the Risk Retention Consultation Party other than with respect to any Excluded Loan as to such party),
in writing of its intention to so release such Mortgaged Property and the bases for such intention, (ii) the Certificate Administrator
shall have posted such notice of the Special Servicer’s intention to so release such Mortgaged Property to the Certificate
Administrator’s Website pursuant to Section 3.13(b) and (iii) in addition to the prior written consent of the Directing
Holder as required above, the Holders of Certificates entitled to a majority of the Voting Rights shall have consented or have
been deemed to have consented to such release within thirty (30) days of the Certificate Administrator’s posting such notice
to the Certificate Administrator’s Website (failure to respond by the end of such 30-day period being deemed consent of the
Holders of the Certificates). To the extent any fee charged by any Rating Agency in connection with rendering such written confirmation
is not paid by the related Mortgagor, such fee is to be an expense of the Trust; provided that the Special Servicer shall
use commercially reasonable efforts to collect such fee from the Mortgagor to the extent permitted under the related Mortgage Loan
documents.


 


(e)         The
Special Servicer shall provide written reports and a copy of any Environmental Assessments in electronic format to the Directing
Holder and the Risk Retention Consultation Party (in each case, other than with respect to any Excluded Loan as to such party),
the Master Servicer and the 17g-5 Information Provider monthly regarding any actions taken by the Special Servicer with respect
to any Mortgaged Property securing a Defaulted Loan, or defaulted Companion Loan as to which the environmental testing contemplated
in subsection (c) above has revealed that either of the conditions set forth in clauses (i) and (ii) of the
first sentence thereof has not been satisfied, in each case until the earlier to occur of satisfaction of both such conditions,
repurchase of the related Mortgage Loan or Trust Subordinate Companion Loan by the applicable Mortgage Loan Seller or release of
the lien of the related Mortgage on such Mortgaged Property.


 


(f)          The
Special Servicer shall notify the Master Servicer of any abandoned and/or foreclosed properties which require reporting to the
Internal Revenue Service and shall provide the Master Servicer with all information regarding forgiveness of indebtedness and required
to be reported with respect to any Mortgage Loan or related Companion Loan that is abandoned or foreclosed and the Master Servicer
shall report to the Internal Revenue Service and the related Mortgagor, in the manner required by applicable law, such information
and the Master Servicer shall report, via Form 1099A or Form 1099C (or any successor form), all forgiveness of indebtedness and
abandonment and foreclosure to the extent such information has


 



     -261-


     


    

 


been provided to the Master Servicer by the Special Servicer. Upon
request, the Master Servicer shall deliver a copy of any such report to the Trustee and the Certificate Administrator.


 


(g)         The
Special Servicer shall have the right to determine, in accordance with the Servicing Standard, the advisability of the maintenance
of an action to obtain a deficiency judgment if the state in which the Mortgaged Property is located and the terms of the Mortgage
Loan (and if applicable, the related Companion Loan) permit such an action.


 


(h)         The
Special Servicer shall maintain accurate records, prepared by one of its Servicing Officers, of each Final Recovery Determination
in respect of a Defaulted Loan (other than with respect to a Non-Serviced Mortgage Loan) or defaulted Companion Loan or any REO
Property (other than any Non-Serviced Mortgaged Property) and the basis thereof. Each Final Recovery Determination shall be evidenced
by an Officer’s Certificate promptly delivered to the Trustee, the Certificate Administrator, the Directing Holder and the
Risk Retention Consultation Party (but in the case of the Directing Holder and the Risk Retention Consultation Party, other than
with respect to any Excluded Loan as to such party) and the Master Servicer and in no event later than the next succeeding P&I
Advance Determination Date.


 


Section 3.10     Trustee
and Custodian to Cooperate; Release of Mortgage Files.  (a) Upon the payment in full of any Mortgage Loan or Trust
Subordinate Companion Loan (other than a Non-Serviced Mortgage Loan), or the receipt by the Master Servicer or the Special Servicer,
as the case may be, of a notification that payment in full shall be escrowed in a manner customary for such purposes, the Master
Servicer or the Special Servicer, as the case may be, will promptly notify the Trustee and the Custodian and request delivery
of the related Mortgage File. Any such notice and request shall be in the form of a Request for Release signed by a Servicing
Officer and shall include a statement to the effect that all amounts received or to be received in connection with such payment
which are required to be deposited in the Collection Account pursuant to Section 3.04(a) or remitted to the Master Servicer
to enable such deposit, have been or will be so deposited. Within three (3) Business Days (or within such shorter period as release
can reasonably be accomplished if the Master Servicer or the Special Servicer notifies the Custodian of an exigency) of receipt
of such notice and request, the Custodian shall release the related Mortgage File to the Master Servicer or the Special Servicer,
as the case may be; provided that in the case of the payment in full of a Serviced Companion Loan or its related Mortgage
Loan, the related Mortgage File shall not be released by the Custodian unless the related Serviced Whole Loan is paid in full.
No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Collection
Account.


 


(b)         From
time to time as is appropriate for servicing or foreclosure of any Mortgage Loan (other than any Non-Serviced Mortgage Loan) (and
any related Companion Loan), the Master Servicer or the Special Servicer shall deliver to the Custodian a Request for Release signed
by a Servicing Officer. Upon receipt of the foregoing, the Custodian shall deliver the Mortgage File or any document therein to
the Master Servicer or the Special Servicer (or a designee), as the case may be. Upon return of such Mortgage File or such document
to the Custodian, or the delivery to the Trustee and the Custodian of a certificate of a Servicing Officer of the Master Servicer
or the Special Servicer, as the case may be, stating that such Mortgage Loan (and, in the case of a Serviced Whole Loan, the related
Companion Loan), was liquidated and that all amounts received or to be received in connection with such liquidation which are


 



     -262-


     


    

 


required
to be deposited into the Collection Account (including amounts related to the related Companion Loan, if applicable) pursuant to
Section 3.04(a) have been or will be so deposited, or that such Mortgage Loan has become an REO Property, a copy of the
Request for Release shall be released by the Custodian to the Master Servicer or the Special Servicer (or a designee), as the case
may be, with the original being released upon termination of the Trust.


 


(c)         Within
three (3) Business Days (or within such shorter period as delivery can reasonably be accomplished if the Special Servicer notifies
the Trustee of an exigency) of receipt thereof, the Trustee shall execute and deliver to the Special Servicer any court pleadings,
requests for trustee’s sale or other documents necessary to the foreclosure or trustee’s sale in respect of a Mortgaged

a related Companion Loan) or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by
the Mortgage Note or Mortgage or otherwise available at law or in equity. The Special Servicer shall be responsible for the preparation
of all such documents and pleadings. When submitted to the Trustee for signature, such documents or pleadings shall be accompanied
by a certificate of a Servicing Officer requesting that such pleadings or documents be executed by the Trustee and certifying as
to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee will not invalidate
or otherwise affect the lien of the Mortgage, except for the termination of such a lien upon completion of the foreclosure or trustee’s
sale. The Trustee shall not be required to review such documents for their sufficiency or enforceability.


 


With respect to each
Servicing Shift Whole Loan, on and after the related Servicing Shift Securitization Date, if pursuant to the related Co-Lender

PSA, and as appropriate for enforcing the terms of a Non-Serviced Mortgage Loan, the applicable Non-Serviced Master Servicer requests
delivery to it of the original Mortgage Note for a Non-Serviced Mortgage Loan, then the Custodian shall release or cause the release
of such original Mortgage Note to such Non-Serviced Master Servicer or its designee.


 


Section 3.11     Servicing
Compensation.  (a) As compensation for its activities hereunder, the Master Servicer shall be entitled to receive
the Servicing Fee with respect to each Mortgage Loan, Serviced Companion Loan and REO Loan (other than the portion of any REO
Loan related to any Non-Serviced Companion Loan) (including Specially Serviced Loans and any Non-Serviced Mortgage Loan constituting
a “specially serviced loan” under any related Non-Serviced PSA). As to each Mortgage Loan, Companion Loan and REO
Loan, the Servicing Fee shall accrue from time to time at the Servicing Fee Rate and shall be computed on the basis of the Stated
Principal Balance of such Mortgage Loan, Companion Loan or REO Loan, as the case may be, and in the same manner as interest is

interest
payment, for the same period respecting which any related interest payment due on such Mortgage Loan or Companion Loan or deemed
to be due on such REO Loan is computed. The Servicing Fee with respect to any Mortgage Loan, Companion Loan or REO Loan shall
cease to accrue if a Liquidation Event occurs with respect to the related Mortgage Loan, except that if such Mortgage Loan is
part of a Serviced Whole Loan and such Serviced Whole Loan continues to be serviced and administered under this Agreement notwithstanding
such Liquidation Event, then the applicable Servicing Fee shall continue to accrue and be payable as if such Liquidation Event
did not occur. The Servicing Fee shall be payable monthly, on a loan-by-loan basis, from payments of interest on each Mortgage
Loan, Companion Loan and REO Revenues allocable as interest on each REO Loan, and as otherwise provided by Section 3.05(a).
The Master Servicer shall be entitled to recover unpaid Servicing Fees in respect of any Mortgage Loan, Companion Loan or REO
Loan out of that portion of related payments, Insurance and Condemnation Proceeds, Liquidation Proceeds and REO Revenues (in the
case of an REO Loan) allocable as recoveries of interest, to the extent permitted by Section 3.05(a). Except as set forth
in the next two sentences, the third paragraph of this Section 3.11(a), Section 6.03, Section 6.05 and Section
7.01(c), the right to receive the Servicing Fee may not be transferred in whole or in part (except in connection with a transfer
of all of the Master Servicer’s duties and obligations hereunder to a successor servicer in accordance with the terms hereof).
With respect to each Serviced Pari Passu Companion Loan, the Servicing Fee shall be payable to the Master Servicer from amounts
payable in respect of such Serviced Pari Passu Companion Loan, subject to the terms of the related Intercreditor Agreement.


 


The Master Servicer shall
be entitled to retain, and shall not be required to deposit in the Collection Account pursuant to Section 3.04(a), additional
servicing compensation (other than with respect to a Non-Serviced Mortgage Loan) in the form of the following amounts to the extent
collected from the related Mortgagor: (i) 100% of Excess Modification Fees related to any modifications, waivers, extensions or
amendments of any Non-Specially Serviced Loans (including any related Serviced Companion Loans, to the extent not prohibited by
the related Intercreditor Agreement and that do not involve a Major Decision and 50% of Excess Modification Fees related to any
modifications, waivers, extensions or amendments of any Mortgage Loans (other than any Non-Serviced Mortgage Loan) and any related
Serviced Companion Loans that are not Specially Serviced Loans to the extent not prohibited by the related Intercreditor Agreement
and that involve one or more Major Decisions (whether or not processed by the Special Servicer), (ii) 100% of all assumption application
fees received on any Mortgage Loans, only for which the Master Servicer is processing the underlying assumption related transaction
(including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) (whether or
not the consent of the Special Servicer is required) and 100% of all defeasance fees (provided that any such defeasance
fee will not include any Modification Fees or waiver fees in connection with a transaction for which the consent or approval of
the Special Servicer is required (and specifically excluding any defeasance fees)); (iii) 100% of assumption, waiver, processing,
consent and earnout fees, and other similar fees pursuant to Section 3.08 and Section 3.18 or other actions performed
in connection with this Agreement on the Non-Specially Serviced Loans (including any related Serviced Companion Loan, to the extent
not prohibited by the related Intercreditor Agreement), which do not involve a Major Decision; (iv) 50% of all assumption, waiver,
processing, consent and earnout fees, and other similar fees (other than assumption application and defeasance fees), pursuant
to Section 3.08 and Section 3.18 on any Non-Specially Serviced Loan (including any


 



     -264-


     


    

 


related Serviced Companion Loan,
to the extent not prohibited by the related Intercreditor Agreement) which involve a Major Decision (whether or not processed by
the Special Servicer) and only to the extent that all amounts then due and payable with respect to the related Mortgage Loan or
any related Serviced Companion Loan have been paid; (v) 100% of charges by the Master Servicer collected for checks returned for
insufficient funds and charges for beneficiary statements or demands actually paid by the related Mortgagors relating to the accounts
held by the Master Servicer; and (vi) late payment charges and default interest paid by the Mortgagors (that accrued while the
related Mortgage Loans (other than any Non-Serviced Mortgage Loan) or any related Serviced Companion Loan (to the extent not prohibited
by the related Intercreditor Agreement) were not Specially Serviced Loans), but only to the extent such late payment charges and
default interest are not needed to pay interest on Advances or certain additional trust fund expenses incurred with respect to
the related Mortgage Loan or, if provided under the related Intercreditor Agreement, any related Serviced Companion Loan since
the Closing Date. Subject to Section 3.11(d), the Master Servicer shall also be entitled to additional servicing compensation
in the form of: (i) Penalty Charges to the extent provided in Section 3.11(d), (ii) interest or other income earned on deposits
relating to the Trust Fund in the Collection Account or the Companion Distribution Account in accordance with Section 3.06(b)
(but only to the extent of the Net Investment Earnings, if any, with respect to such account for the period from and including
the prior Distribution Date to and including the P&I Advance Date related to the current Distribution Date), (iii) interest
or other income earned on deposits in the Servicing Account which are not required by applicable law or the related Mortgage Loan
or Trust Subordinate Companion Loan to be paid to the Mortgagor and (iv) the difference, if positive, between Prepayment Interest
Excess and Prepayment Interest Shortfalls collected on the Mortgage Loans, the Trust Subordinate Companion Loans and any Serviced
Pari Passu Companion Loan, during the related Collection Period to the extent not required to be paid as Compensating Interest
Payments. The Master Servicer shall be required to pay out of its own funds all expenses incurred by it in connection with its
servicing activities hereunder (including, without limitation, payment of any amounts due and owing to any of its Sub-Servicers
and the premiums for any blanket Insurance Policy insuring against hazard losses pursuant to Section 3.07), if and to the
extent such expenses are not payable directly out of the Collection Account and the Master Servicer shall not be entitled to reimbursement
therefor except as expressly provided in this Agreement.


 


With respect to any of
the preceding fees as to which both the Master Servicer and the Special Servicer are entitled to receive a portion thereof, the
Master Servicer and the Special Servicer shall each have the right in their sole discretion, but not any obligation, to reduce
or elect not to charge its respective portion of such fee; provided that without the consent of the affected party (A) neither
the Master Servicer nor the Special Servicer shall have the right to reduce or elect not to charge the portion of any such fee
due to the other and (B) to the extent either the Master Servicer or the Special Servicer exercises its right to reduce or elect
not to charge its respective portion in any such fee, the party that reduced or elected not to charge its respective portion of
such fee shall not have any right to share in any part of the other party’s portion of such fee. If the Master Servicer decides
not to charge any fee, the Special Servicer shall nevertheless be entitled to charge its portion of the related fee to which the
Special Servicer would have been entitled if the Master Servicer had charged a fee and the Master Servicer shall not be entitled
to any of such fee charged by the Special Servicer.


 






     -265-


     


    

 


Notwithstanding anything
herein to the contrary, the Master Servicer and the Special Servicer shall each be entitled to charge and retain reasonable review
fees in connection with any Mortgagor request to the extent such fees are not prohibited under the related Mortgage Loan documents
and are actually paid by or on behalf of the related Mortgagor. Notwithstanding anything herein to the contrary, KeyBank National
Association may, at its option, assign or pledge to any third party or retain for itself the Transferable Servicing Interest; provided,
however, that in the event of any resignation or termination of such Master Servicer, all or any portion of the Transferable
Servicing Interest may be reduced by the Trustee to the extent reasonably necessary (in the sole discretion of the Trustee) for
the Trustee to obtain a qualified successor master servicer that meets the requirements of Section 6.05 and who requires
market-rate servicing compensation that accrues at a per annum rate in excess of the Retained Fee Rate, and any such assignment
of the Transferable Servicing Interest shall, by its terms be expressly subject to the terms of this Agreement and such reduction.
The Master Servicer shall pay the Transferable Servicing Interest to the holder of the Transferable Servicing Interest at such
time and to the extent the Master Servicer is entitled to receive payment of its Servicing Fees hereunder, notwithstanding any
resignation or termination of KeyBank National Association hereunder (subject to reduction pursuant to the preceding sentence).


 


(b)         As
compensation for its activities hereunder, the Special Servicer shall be entitled to receive the Special Servicing Fee with respect
to each Specially Serviced Loan and REO Loan (other than a Non-Serviced Mortgage Loan and any REO Loan relating to a Non-Serviced
Mortgaged Property). As to each Specially Serviced Loan and REO Loan, the Special Servicing Fee shall accrue from time to time
at the Special Servicing Fee Rate and shall be computed on the basis of the Stated Principal Balance of such Specially Serviced
Loan or REO Loan, as the case may be, and in the same manner as interest is calculated on the Specially Serviced Loans or REO Loans,
as the case may be, and, in connection with any partial month interest payment, for the same period respecting which any related
interest payment due on such Specially Serviced Loan or deemed to be due on such REO Loan is computed. The Special Servicing Fee
with respect to any Specially Serviced Loan or REO Loan shall cease to accrue if a Liquidation Event occurs with respect to the
related Mortgage Loan or Trust Subordinate Companion Loan. The Special Servicing Fee shall be payable monthly, on a loan-by-loan
basis, in accordance with the provisions of Section 3.05(a). The right to receive the Special Servicing Fee may not be transferred
in whole or in part except in connection with the transfer of all of the Special Servicer’s responsibilities and obligations
under this Agreement. The Special Servicer shall not be entitled to any Special Servicing Fees with respect to a Non-Serviced Mortgage
Loan.


 


(c)         Additional
servicing compensation in the form of (i) 100% of all Excess Modification Fees related to modifications, waivers, extensions or
amendments of any Specially Serviced Loans, (ii) 100% of all assumption application fees received on any Mortgage Loans and any
related Serviced Companion Loan (to the extent not prohibited by the related Intercreditor Agreement) only for which the Special
Servicer is processing the underlying assumption related transaction, (iii) 100% of all assumption fees and other related fees
received with respect to the Specially Serviced Loans, (iv) 100% of waiver, consent and earnout fees and similar fees, pursuant
to Section 3.08 and Section 3.18 or other actions performed in connection with this Agreement on the Specially Serviced
Loans or certain other similar fees paid by the related Mortgagor, (v) 50% of all Excess Modification Fees and assumption fees,
waiver fees,


 



     -266-


     


    

 


consent fees, earnout fees, and similar fees pursuant to Section 3.08 or Section 3.18 received with
respect to all Non-Specially Serviced Loans (including any related Serviced Companion Loan, to the extent not prohibited by the
related Intercreditor Agreement) (excluding any Non-Serviced Mortgage Loan) that involve one or more Major Decisions, and (vi)
100% of charges by the Special Servicer for checks returned for insufficient funds, charges for beneficiary statements or demands,
in each case, relating to the accounts held by the Special Servicer, shall be promptly paid to the Special Servicer by the Master
Servicer (or directly from the related Mortgagor) to the extent such fees are paid by the Mortgagor and shall not be required to
be deposited in the Collection Account pursuant to Section 3.04(a). Subject to Section 3.11(d), the Special Servicer
shall also be entitled to additional servicing compensation in the form of: (i) Penalty Charges to the extent provided in Section
3.11(d) and (ii) interest or other income earned on deposits relating to the Trust Fund in the REO Account and Loss of Value
Reserve Fund in accordance with Section 3.06(b) (but only to the extent of the Net Investment Earnings, if any, with respect
to such account for the period from and including the prior Distribution Date to and including the P&I Advance Date related
to such Distribution Date). In addition, the Special Servicer shall also be entitled to retain as additional servicing compensation
(other than with respect to any Non-Serviced Mortgage Loan) reasonable review fees in connection with any Mortgagor request to
the extent such review fees are not prohibited under the related Mortgage Loan documents, and only to the extent actually paid
by the related Mortgagor. The Special Servicer shall also be entitled to additional servicing compensation in the form of a Workout
Fee with respect to each Corrected Loan at the Workout Fee Rate on such Corrected Loan for so long as it remains a Corrected Loan;
provided, however, that after receipt by the Special Servicer of Workout Fees with respect to such Corrected Loan
in an amount equal to $25,000, any Workout Fees in excess of such amount shall be reduced by the Excess Modification Fee Amount;
provided, further, however, that, other than with respect to the Yorkshire & Lexington Towers Whole Loan, in
the event the Workout Fee collected over the course of such workout calculated at the Workout Fee Rate is less than $25,000, then
the Special Servicer shall be entitled to an amount from the final payment on the related Corrected Loan (including any related
Serviced Companion Loan) that would result in the total Workout Fees payable to the Special Servicer in respect of that Corrected
Loan (including any related Serviced Companion Loan) to be $25,000. The Workout Fee shall be reduced (but not below zero) pursuant
to the preceding sentence with respect to each collection on such Corrected Loan from which fee would otherwise be payable until
an amount equal to such Excess Modification Fee Amount has been deducted in full. The Workout Fee with respect to any Corrected
Loan will cease to be payable if such loan again becomes a Specially Serviced Loan; provided that a new Workout Fee will
become payable if and when such Specially Serviced Loan again becomes a Corrected Loan. The Special Servicer shall not be entitled
to any Workout Fee with respect to a Non-Serviced Mortgage Loan. If the Special Servicer is terminated (other than for cause) or
resigns, it shall retain the right to receive any and all Workout Fees payable in respect of Mortgage Loans or any related Companion
Loan that became Corrected Loans prior to the time of that termination or resignation except the Workout Fees will no longer be
payable if the Corrected Loan subsequently becomes a Specially Serviced Loan. If the Special Servicer resigns or is terminated
(other than for cause), it will receive any Workout Fees payable on Specially Serviced Loans for which the resigning or terminated
Special Servicer had determined to grant a forbearance or cured the event of default through a modification, restructuring or workout
negotiated by the Special Servicer and evidenced by a signed writing, but which had not as of the time the Special Servicer resigned
or


 



     -267-


     


    

 


was terminated become a Corrected Loan solely because the Mortgagor had not had sufficient time to make three consecutive timely
Periodic Payments and which subsequently becomes a Corrected Loan as a result of the Mortgagor making such three consecutive timely
Periodic Payments except the Workout Fees will no longer be payable if the Corrected Loan subsequently becomes a Specially Serviced
Loan. The successor special servicer shall not be entitled to any portion of such Workout Fees. The Special Servicer shall not
be entitled to receive any Workout Fees after termination for cause. A Liquidation Fee will be payable with respect to each Specially
Serviced Loan (other than a Non-Serviced Mortgage Loan) or REO Property (other than a Non-Serviced Mortgaged Property) as to which
the Special Servicer receives any Liquidation Proceeds or Insurance and Condemnation Proceeds subject to the exceptions set forth
in the definition of Liquidation Fee (such Liquidation Fee to be paid out of such Liquidation Proceeds, Insurance and Condemnation
Proceeds). If, however, Liquidation Proceeds or Insurance and Condemnation Proceeds are received with respect to any Corrected
Loan and the Special Servicer is properly entitled to a Workout Fee, such Workout Fee will be payable based on and out of the portion
of such Liquidation Proceeds and Insurance and Condemnation Proceeds that constitute principal and/or interest on such Mortgage
Loan. Notwithstanding anything herein to the contrary, the Special Servicer shall only be entitled to receive a Liquidation Fee
or a Workout Fee, but not both, with respect to proceeds on any Mortgage Loan or Trust Subordinate Companion Loan. Notwithstanding
the foregoing, with respect to any Companion Loan, the Liquidation Fee, Workout Fee and Special Servicing Fees, if any, will be
computed as provided in the related Intercreditor Agreement or to the extent such Intercreditor Agreement is silent or refers to
this Agreement or indicates such fees are paid in accordance with this Agreement, as provided herein as though such Companion Loan
were a Mortgage Loan. Subject to Section 3.11(d), the Special Servicer will also be entitled to additional fees in the form
of Penalty Charges. The Special Servicer shall be required to pay out of its own funds all expenses incurred by it in connection
with its servicing activities hereunder (including, without limitation, payment of any amounts, other than management fees in respect
of REO Properties, due and owing to any of its Sub-Servicers and the premiums for any blanket Insurance Policy obtained by it insuring
against hazard losses pursuant to Section 3.07), if and to the extent such expenses are not expressly payable directly out
of the Collection Account or the REO Account, and the Special Servicer shall not be entitled to reimbursement therefor except as
expressly provided in this Agreement.


 


With respect to any of
the preceding fees as to which both the Master Servicer and the Special Servicer are entitled to receive a portion thereof, the
Master Servicer and the Special Servicer shall each have the right in their sole discretion, but not any obligation, to reduce
or elect not to charge its respective portion of such fee; provided that (A) neither the Master Servicer nor the Special
Servicer shall have the right to reduce or elect not to charge the portion of any such fee due to the other and (B) to the extent
either the Master Servicer or the Special Servicer exercises its right to reduce or elect not to charge its respective portion
in any such fee, the party that is reduced or elected not to charge its respective portion of such fee shall not have any right
to share in any part of the other party’s portion of such fee. If the Master Servicer decides not to charge any fee, the
Special Servicer shall nevertheless be entitled to charge its portion of the related fee to which the Special Servicer would have
been entitled if the Master Servicer had charged a fee and the Master Servicer shall not be entitled to any of such fee charged
by the Special Servicer.

(d)         In
determining the compensation of the Master Servicer or the Special Servicer, as applicable, with respect to Penalty Charges, on
any Distribution Date, the aggregate Penalty Charges collected on any Mortgage Loan (other than a Non-Serviced Mortgage Loan) and
any related Companion Loan since the prior Distribution Date shall be applied (in such order) to reimburse (i) the Master Servicer,
the Special Servicer or the Trustee for interest on Advances on such Mortgage Loan or related Companion Loan, if applicable (and,
in connection with a Non-Serviced Mortgage Loan, the applicable Non-Serviced Master Servicer, the applicable Non-Serviced Special
Servicer or the applicable Non-Serviced Trustee for interest on the servicing advances made by any such party with respect to a
Non-Serviced Whole Loan pursuant to the applicable Non-Serviced PSA, to the extent not prohibited by the applicable Non-Serviced
Intercreditor Agreement) due on such Distribution Date, (ii) the Trust for all interest on Advances previously paid to the Master
Servicer or the Trustee pursuant to Section 3.05(a)(vi) hereof (and, in connection with a Non-Serviced Mortgage Loan, the
related trust for all interest on servicing advances reimbursed by such trust to any party under the applicable Non-Serviced PSA,
which resulted in an additional expense for the Trust, to the extent not prohibited by the applicable Non-Serviced Intercreditor
Agreement) with respect to such Mortgage Loan or related Companion Loan, if applicable and (iii) the Trust for all additional expenses
of the Trust (other than Special Servicing Fees, Workout Fees and Liquidation Fees), including without limitation, inspections
by the Special Servicer and all unpaid Advances incurred since the Closing Date with respect to such Mortgage Loan. Penalty Charges
(other than with respect to a Non-Serviced Mortgage Loan, which shall be payable as additional servicing compensation under the
related Non-Serviced PSA) remaining thereafter shall be distributed to the Master Servicer, if and to the extent accrued while
such Mortgage Loan and any related Companion Loan was a Non-Specially Serviced Loan, and to the Special Servicer, if and to the
extent accrued on such Mortgage Loan during the period such Mortgage Loan was a Specially Serviced Loan or REO Loan. Any Penalty
Charges paid or payable as additional servicing compensation to the Master Servicer and the Special Servicer shall be distributed
between the Master Servicer and the Special Servicer, on a pro rata basis, based on the Master Servicer’s and the
Special Servicer’s respective entitlements to such compensation described in the previous sentence. If the Special Servicer
has partially waived any Penalty Charge (part of which accrued prior to the related Servicing Transfer Event), any collections
in respect of such Penalty Charge shall be shared by the Master Servicer only to the extent of the Penalty Charges accrued and
not waived prior to the related Servicing Transfer Event. If the Master Servicer has partially waived any Penalty Charge, any collections
in respect of such Penalty Charge shall be shared pro rata by the Master Servicer and the Special Servicer based on the respective
portions of such Penalty Charge to which each would otherwise have been entitled. Notwithstanding the foregoing, Penalty Charges
with respect to any Companion Loan will be allocated pursuant to the applicable Intercreditor Agreement after payment of all related
Advances and interest thereon and additional expenses of the Trust in accordance with this Section 3.11(d).


 


If a Servicing Shift
Whole Loan becomes a Specially Serviced Loan prior to the applicable Servicing Shift Securitization Date, the Special Servicer
shall service and administer such Servicing Shift Whole Loan and any related REO Property in the same manner as any other Specially
Serviced Loan or Serviced REO Property and shall be entitled to all rights and compensation earned with respect to such Serviced
Whole Loan as Special Servicer of such Serviced Whole Loan. With respect to a Servicing Shift Mortgage Loan, prior to the applicable
Servicing Shift Securitization Date, no other special servicer will be entitled to any such

obligations. If a Servicing Shift Whole Loan is still a Specially Serviced Loan on the applicable Servicing Shift Securitization
Date, the Non-Serviced Special Servicer and the Special Servicer shall be entitled to compensation with respect to such Servicing
Shift Whole Loan as if the Special Servicer were being terminated as the Special Servicer with respect to such Servicing Shift
Whole Loan and the Non-Serviced Special Servicer were replacing the Special Servicer as the successor Special Servicer with respect
to such Servicing Shift Whole Loan.


 


If a Servicing Shift
Whole Loan is being specially serviced on the Servicing Shift Securitization Date, the Special Servicer shall be entitled to compensation
for the period during which it acted as Special Servicer with respect to such Whole Loan, including its share of any liquidation
or workout fees and any additional servicing compensation as well as all surviving indemnity and other rights in respect of such
special servicing role under this Agreement.


 


(e)         With
respect to each Distribution Date, the Special Servicer shall deliver or cause to be delivered to the Master Servicer within two
(2) Business Days following the Determination Date, and the Master Servicer shall deliver, to the extent it has received, to the
Certificate Administrator, without charge and on the same day as the Master Servicer is required to deliver the CREFC® Investor
Reporting Package for such Distribution Date, an electronic report (which may include HTML, word or excel compatible format, clean

that discloses and contains an itemized listing of any Disclosable Special Servicer Fees received by the Special Servicer or any
of its Affiliates, if any, with respect to such Distribution Date; provided that no such report shall be due in any month
during which no Disclosable Special Servicer Fees were received.


 


(f)          The
Special Servicer and its Affiliates shall be prohibited from receiving or retaining any compensation or any other remuneration
(including, without limitation, in the form of commissions, brokerage fees, rebates, or as a result of any other fee-sharing arrangement)
from any Person (including, without limitation, the Trust, any Mortgagor, any property manager, any guarantor or indemnitor in
respect of a Mortgage Loan and any purchaser of any Mortgage Loan or REO Property) in connection with the disposition, workout
or foreclosure of any Mortgage Loan, the management or disposition of any REO Property, or the performance of any other special
servicing duties under this Agreement, other than as expressly provided in this Section 3.11; provided that such
prohibition shall not apply to Permitted Special Servicer/Affiliate Fees.


 


(g)         Pursuant
to the CREFC® License Agreement, CREFC® shall be paid (according to the payment instructions set
forth on Exhibit JJ hereto or such other payment instructions as CREFC® may provide to the Master Servicer
in writing at least two Business Days prior to the Master Servicer Remittance Date) the CREFC® Intellectual Property

Collection of Financial Statements.   (a) The Master Servicer (other than with respect to a Specially Serviced
Loan or REO Loan) shall perform (at its own expense), or shall cause to be performed (at its own expense), a physical inspection
of each Mortgaged Property relating to a Mortgage Loan (other than a Mortgaged Property securing a Non-Serviced Mortgage Loan,
which is subject to inspection pursuant to the related Non-Serviced PSA) or Trust Subordinate Companion Loan with a Stated Principal
Balance of (i) $2,000,000 or more at least once every twelve (12) months and (ii) less than $2,000,000 at least once every twenty-four

in the previous twelve (12) months, the Master Servicer shall not be required to perform or cause to be performed, such physical
inspection; provided, further, that if any scheduled payment becomes more than sixty (60) days delinquent on the
related Mortgage Loan or Trust Subordinate Companion Loan, the Special Servicer shall inspect or cause to be inspected the related
Mortgaged Property as soon as practicable after such Mortgage Loan becomes a Specially Serviced Loan and annually thereafter for
so long as such Mortgage Loan remains a Specially Serviced Loan. The cost of such inspection by the Special Servicer pursuant
to the immediately preceding sentence shall be, to the extent not paid by the related Mortgagor, reimbursed first from Default
Interest and late charges constituting additional compensation of the Special Servicer on the related Mortgage Loan (but with
respect to any Serviced Whole Loan, only from amounts available for such purpose under the related Intercreditor Agreement) and
then from the Collection Account, as an expense of the Trust, pursuant to Section 3.05(a)(ii), provided that, with
respect to a Serviced Whole Loan, such cost shall be payable, subject to the terms of the related Intercreditor Agreement (i)

Standard Highline Non-Trust Senior Subordinate Companion Loan and then, to the Standard Highline Trust Subordinate Companion
Loan) and then, from any related AB Mortgage Loan (and any Pari Passu Companion Loan(s), on a pro rata basis) (provided
that, with respect to any AB Subordinate Companion Loan, the foregoing shall not limit or otherwise modify the terms of the
related Intercreditor Agreement pursuant to which any amounts collected with respect to the related Whole Loan are allocated to
the related Serviced Mortgage Loan and AB Subordinate Companion Loan), in each case, prior to being payable out of general collections.

(i)          Within
forty-five (45) days after receipt of a quarterly operating statement, if any, commencing following the receipt of such quarterly

provided, however, that any analysis or report with respect to the first calendar quarter of each year shall not
be required to the extent provided in the then-current applicable CREFC® guidelines (it being understood that as

calendar quarter (in each year) is not required for a Mortgaged Property unless such Mortgaged Property is analyzed on a trailing
12 month basis, or if the related Serviced Mortgage Loan or Trust Subordinate Companion Loan is on the CREFC® Servicer
Watch List). The Master Servicer (with respect to Mortgage Loans or Trust Subordinate Companion Loans that are not Specially Serviced
Loans or REO Loans) or the Special Servicer (with respect to Specially Serviced Loans or REO Loans), as applicable, shall deliver
or make available copies (in electronic format) each CREFC® Operating Statement Analysis Report and the related

operating statement for the calendar year ending December 31, 2018, a CREFC® NOI Adjustment Worksheet (but only
to the extent the related Mortgagor is required by the related Mortgage Loan documents to deliver and does deliver, or otherwise
agrees to provide and does provide, such information), presenting the computation to “normalize” the full year net
operating income and debt service coverage numbers used by the Master Servicer in preparing the CREFC® Comparative

Not later than 5:00 p.m.
(New York City time) on the Master Servicer Remittance Date beginning December 2017, the Master Servicer shall deliver to the Certificate
Administrator the CREFC® Schedule AL File in EDGAR-Compatible Format; provided that the Master Servicer shall
have no obligation to prepare or deliver any such CREFC® Schedule AL File unless the Depositor has delivered the
items required by Section 2.01(i). If the CREFC® Schedule AL File is not provided by 5:00 p.m. (New York
City time) on the Master Servicer Remittance Date, the Certificate Administrator shall request such CREFC® Schedule
AL File from the Master Servicer via email at KC_Investor_Reporting@KeyBank.com, with a copy to the Depositor at chuck.lee@credit-suisse.com.
In preparing the CREFC® Schedule AL File and any Schedule AL Additional File for any given Distribution Date, and
without any due diligence, investigation or verification, the Master Servicer shall be entitled to conclusively rely, absent manifest
error, on the content, completeness, accuracy and compliance with any applicable requirements of Items 1111(h) and 1125 of Regulation
AB and Item 601(b) of Regulation S-K under the Securities Act as in effect on the Closing Date of the Initial Schedule AL File,
any Initial Schedule AL Additional File and Annex A-1 to the Prospectus. The Master Servicer may concurrently with the delivery
of the related CREFC® Schedule AL File, deliver any related Schedule AL Additional File in EDGAR-Compatible Format
to the Certificate Administrator. The CREFC® Schedule AL File and the Schedule AL Additional File shall each be
a single file. Neither the Certificate Administrator nor the Master Servicer shall be required to combine multiple CREFC®
Schedule AL Files or Schedule AL Additional Files, unless, solely with respect to the Master Servicer, multiple Sub-Servicers prepare
and submit such CREFC® Schedule AL Files or Schedule AL Additional Files to the Master Servicer. The Certificate
Administrator shall not be required to review, redact, reconcile, edit or verify the content, completeness or accuracy of the information
contained in any CREFC® Schedule AL File or any Schedule AL Additional File. The Certificate Administrator shall
not be deemed to have actual knowledge of the contents of any CREFC® Schedule AL File or Schedule AL Additional
File solely by its receipt thereof.


 


In the absence of manifest
error, the Master Servicer shall be entitled to conclusively rely upon, without investigation or inquiry, any information and reports
delivered to it by any third party, and the Certificate Administrator shall be entitled to conclusively rely upon the Master Servicer’s
reports and the Special Servicer’s reports and any information provided by the Trustee, without any duty or obligation to
recompute, verify or recalculate any of the amounts and other information stated therein.


 


(e)         The
Special Servicer shall deliver to the Master Servicer the reports and information required of the Special Servicer pursuant to
Section 3.12(b) and Section 3.12(c), and the Master Servicer shall deliver or make available to the Certificate Administrator
the reports and data files set forth in Section 3.12(b). The Master Servicer may, absent manifest error, conclusively rely
on the reports and/or data to be provided by the Special Servicer pursuant to Section 3.12(b) and Section 3.12(c).
The Certificate Administrator may, absent manifest error, conclusively rely on the reports and/or data to be provided by the Master
Servicer pursuant to Section 3.12(b). In the case of information or reports to be furnished by the Master Servicer to the
Certificate Administrator pursuant to Section 3.12(b), to the extent that such information or reports are, in turn, based
on information or reports to be provided by the Special Servicer pursuant to Section 3.12(b) or Section 3.12(c) and
to the extent that such reports are to be prepared and delivered by the Special Servicer pursuant to Section 3.12(b) or
Section 3.12(c), the


 



     -275-


     


    

 


Master Servicer shall have no obligation to provide such information or reports to the Certificate
Administrator until it has received the requisite information or reports from the Special Servicer, and the Master Servicer shall
not be in default hereunder due to a delay in providing the reports required by Section 3.12(b) caused by the Special Servicer’s
failure to timely provide any information or report required under Section 3.12(b) or Section 3.12(c) of this Agreement.


 


(f)          Notwithstanding
the foregoing, however, the failure of the Master Servicer or the Special Servicer to disclose any information otherwise required
to be disclosed by this Section 3.12 shall not constitute a breach of this Section 3.12 to the extent the Master
Servicer or the Special Servicer so fails because such disclosure, in the reasonable belief of the Master Servicer or the Special
Servicer, as the case may be, would violate any applicable law or any provision of a Mortgage Loan document prohibiting disclosure
of information with respect to the Mortgage Loans or Mortgaged Properties. The Master Servicer and the Special Servicer may disclose
any such information or any additional information to any Person so long as such disclosure is consistent with applicable law and
the Servicing Standard. The Master Servicer or the Special Servicer may affix to any information provided by it any disclaimer
it deems appropriate in its reasonable discretion (without suggesting liability on the part of any other party hereto).


 


(g)         Unless
otherwise specifically stated herein, if the Master Servicer or the Special Servicer is required to deliver any statement, report
or information under any provisions of this Agreement, the Master Servicer or the Special Servicer, as the case may be, may satisfy
such obligation by (x) physically delivering a paper copy of such statement, report or information, (y) delivering such statement,
report or information in a commonly used electronic format or (z) except with respect to information to be provided to the Certificate
Administrator or any Companion Holder and, prior to the occurrence of a Consultation Termination Event, the Directing Holder, making
such statement, report or information available on the Master Servicer’s or the Special Servicer’s Internet website,
unless this Agreement expressly specifies a particular method of delivery.


 


Notwithstanding anything
to the contrary in the foregoing, the Master Servicer and the Special Servicer shall deliver any required statements, reports or
other information to the Certificate Administrator in an electronic format mutually agreeable to the Certificate Administrator
and the Master Servicer or the Special Servicer, as the case may be. The Master Servicer or the Special Servicer may physically
deliver a paper copy of any such statement, report or information as a temporary measure due to system problems, however, copies
in electronic format shall follow upon the correction of such system problems.


 


Section 3.13     Access
to Certain Information.   (a) Each of the Master Servicer and the Special Servicer shall provide or cause to
be provided to the Certificate Administrator, and the Certificate Administrator shall afford access to any Mortgage Loan Seller
and to any Certificateholder that is a federally insured financial institution, the OCC, the FDIC, the Board of Governors of the
Federal Reserve System of the United States of America and the supervisory agents and examiners of such boards and such corporations,
and any other federal or state banking or insurance regulatory authority that may exercise authority over any such Certificateholder,
and to each Holder of a Non-Registered Certificate, access to any documentation or information regarding the Mortgage Loans (other
than any Non-Serviced


 



     -276-


     


    

 


Mortgage Loan) and, in the case of a Mortgage Loan that is a portion of a Serviced Whole Loan, the related
Companion Loan, and the Trust within its control which may be required by applicable law. At the election of the Master Servicer,
the Special Servicer or the Certificate Administrator, such access may be afforded to such Person identified above by the delivery
of copies of information as requested by such Person and the Master Servicer, the Special Servicer or the Certificate Administrator
shall be permitted to require payment (other than from the Directing Holder (prior to the occurrence of a Consultation Termination
Event) and the Trustee and the Certificate Administrator on its own behalf or on behalf of the Certificateholders, as applicable)
of a sum sufficient to cover the reasonable out-of-pocket costs incurred by it in making such copies. Such access shall (except
as described in the preceding sentence) be afforded without charge but only upon reasonable prior written request and during normal
business hours at the offices of the Certificate Administrator or the Custodian.


 


The failure of the Master
Servicer or the Special Servicer to provide access as provided in this Section 3.13 as a result of a confidentiality obligation
shall not constitute a breach of this Section 3.13. In connection with providing information pursuant to this Section
3.13, the Master Servicer and the Special Servicer may each (i) affix a reasonable disclaimer to any information provided by
it for which it is not the original source (without suggesting liability on the part of any other party hereto); (ii) affix to
any information provided by it a reasonable statement regarding securities law restrictions on such information and/or condition
access to information on (x) the execution of a confidentiality agreement substantially in the form of Exhibit X, or (y)
execution of a “click-through” confidentiality agreement if such information is being provided through the Master Servicer’s
or the Special Servicer’s website; (iii) withhold access to confidential information or any intellectual property; and/or
(iv) withhold access to items of information contained in the Servicing File for any Mortgage Loan if the disclosure of such items
is prohibited by applicable law or the provisions of any related Mortgage Loan documents or would constitute a waiver of the attorney-client
privilege. Notwithstanding any provision of this Agreement to the contrary, the failure of the Master Servicer or the Special Servicer
to disclose any information otherwise required to be disclosed by it pursuant to this Agreement shall not constitute a breach of
this Agreement to the extent that the Master Servicer or the Special Servicer, as the case may be, determines, in its reasonable
good faith judgment consistent with the applicable Servicing Standard, that such disclosure would violate applicable law or any
provision of a Mortgage Loan or Companion Loan document prohibiting disclosure of information with respect to the Mortgage Loans
or Companion Loans or the Mortgaged Properties, constitute a waiver of the attorney-client privilege on behalf of the Trust or
the Trust or otherwise materially harm the Trust or the Trust. Without limiting the generality of the foregoing, the Master Servicer
or the Special Servicer may refrain from disclosing information that it reasonably determines would prejudice the interest of the
Certificateholders with respect to a workout or exercise of remedies as to any particular Mortgage Loan or Trust Subordinate Companion
Loan.


 


Upon the reasonable request
of any Certificateholder or Certificate Owner (or with respect to any AB Subordinate Companion Loan, the holder of such AB Subordinate
Companion Loan) that has delivered an Investor Certification to the Master Servicer or the Special Servicer, as applicable, the
Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans),
as applicable, may provide (or forward electronically) at the expense of such Certificateholder or holder of such AB


 



     -277-


     


    

 


Subordinate
Companion Loan, as applicable, copies of any appraisals, operating statements, rent rolls and financial statements (in each case,
solely relating to the related Serviced Whole Loan, if requested by the holder of an AB Subordinate Companion Loan or a Holder
of any Loan-Specific Certificates) obtained by the Master Servicer or the Special Servicer, as the case may be; provided
that, in connection with such request, the Master Servicer or the Special Servicer, as applicable, may require a written confirmation
executed by the requesting Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special
Servicer, as applicable, generally to the effect that such Person will keep such information confidential and shall use such information
only for the purpose of analyzing asset performance and evaluating any continuing rights the Certificateholder or holder of such
AB Subordinate Companion Loan, as applicable, may have under this Agreement. In addition, upon the reasonable request of any Controlling
Class Certificateholder identified to the Master Servicer (in the case of a Non-Specially Serviced Loan) or the Special Servicer
(in the case of a Specially Serviced Loan) to the Master Servicer’s or the Special Servicer’s reasonable satisfaction
and if the requested information is in the Master Servicer’s or the Special Servicer’s possession, the Master Servicer
or the Special Servicer, as applicable, shall provide or make available (or forward electronically) to such Controlling Class Certificateholder
(at the expense of such Controlling Class Certificateholder) any Excluded Information (available to Privileged Persons through
the Certificate Administrator’s Website but not accessible to such Controlling Class Certificateholder through the Certificate
Administrator’s Website on account of it constituting Excluded Information) relating to any Excluded Controlling Class Loan
with respect to which such Controlling Class Certificateholder is not an Excluded Controlling Class Holder; provided that,
in connection therewith, the Master Servicer or the Special Servicer may require a written confirmation executed by the requesting
Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special Servicer, generally to
the effect that such Person is a Controlling Class Certificateholder, will keep such Excluded Information confidential and is not
a Borrower Party, upon which the Master Servicer or the Special Servicer may conclusively rely. In addition, the Master Servicer
and the Special Servicer shall be entitled to conclusively rely on delivery from a Controlling Class Certificateholder of an investor
certification substantially in the form of Exhibit P-1E that such Controlling Class Certificateholder is not an Excluded
Controlling Class Holder with respect to a particular Mortgage Loan.


 


Notwithstanding anything
to the contrary herein (other than as permitted in the preceding paragraph with respect to any Certificateholder or as specifically
provided for herein with respect to the Directing Certificateholder), unless required by applicable law or court order, no Certificateholder
or beneficial owner shall be given access to, or be provided copies of, the Mortgage Files or Diligence Files.

In the case of the Directing
Holder or a Controlling Class Certificateholder that is not an Excluded Controlling Class Holder, upon delivery of an investor
certification substantially in the form of Exhibit P-1B hereto, such Directing Holder or Controlling Class Certificateholder
shall be entitled to access all information on the Certificate Administrator’s Website. The Master Servicer, the Special
Servicer, the Operating Advisor, the Certificate Administrator and the Trustee may each rely on (i) an investor certification in
the form of Exhibit P-1B hereto from the Directing Holder or a Controlling Class Certificateholder to the effect that such
Person is not an Excluded Controlling Class Holder and (ii) an investor certification in the form of Exhibit P-1D hereto
from the Directing Holder or a Controlling Class Certificateholder to the effect that such Person is an Excluded Controlling Class
Holder with respect to one or more Excluded Controlling Class Loan(s). In the event the Directing Holder or a Controlling Class
Certificateholder becomes an Excluded Controlling Class Holder, such party shall promptly notify each of the Master Servicer, the
Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee in writing substantially in the form of
Exhibit P-1E that such party has become an Excluded Controlling Class Holder with respect to the Excluded Controlling Class
Loan(s) and/or Excluded Loan(s) listed in such notice and shall also provide the Certificate Administrator a notice substantially
in the form of Exhibit P-1F listing each of the CTSLink User ID associated with such Excluded Controlling Class Holder and
directing the Certificate Administrator to restrict such Excluded Controlling Class Holder’s access to the Certificate Administrator’s
Website as and to the extent provided in this Agreement. Upon confirmation from the Certificate Administrator that such access
has been restricted, such Excluded Controlling Class Holder shall submit a new investor certification substantially in the form
of Exhibit P-1E to access the information on the Certificate Administrator’s Website, except that such Excluded Controlling
Class Holder shall not be entitled to access any Excluded Information related to any Excluded Controlling Class Loan(s) and/or
Excluded Loan(s) (unless a loan-by-loan segregation is later performed by the Certificate Administrator in which case such access
shall only be prohibited with respect to the related Excluded Controlling Class Loan(s)) and/or Excluded Loan(s) made available
on the Certificate Administrator’s Website. With respect to any Excluded Information sent for posting on the Certificate
Administrator’s Website, each of the Master Servicer, the Special Servicer and the Operating Advisor shall mark or label
such information as “Excluded Information” prior to delivery to the Certificate Administrator, and the Certificate
Administrator shall segregate on the Certificate Administrator’s Website such Excluded Information (and, if possible, on
loan-by-loan basis) from information relating to other Mortgage Loans or Whole Loans, as applicable.


 


Notwithstanding anything
herein to the contrary, each of the Master Servicer, the Special Servicer, the Operating Advisor and the Certificate Administrator
shall be entitled to conclusively assume that the Directing Holder and all beneficial owners of the Certificates of the Controlling
Class are not Excluded Controlling Class Holders except to the extent that the Master Servicer, the Special Servicer, the Operating
Advisor or the Certificate Administrator, as applicable, has received a notice substantially in the form of Exhibit P-1E
from the Directing Holder or a Controlling Class Certificateholder that it has become an Excluded Controlling Class Holder. None
of the Master Servicer, the Special Servicer, the Operating Advisor or the Certificate Administrator shall be liable for any communication
to the Directing Holder or a Controlling Class Certificateholder that is an Excluded Controlling Class Holder or disclosure of
any information relating to an Excluded Controlling Class Loan (including any related Excluded Information delivered to the Certificate
Administrator for posting to the Certificate


 



     -283-


     


    

 


Administrator’s Website) if the Master Servicer, the Special Servicer, the Operating
Advisor or the Certificate Administrator, as applicable, did not receive prior written notice that the related Mortgage Loan is
an Excluded Controlling Class Loan and/or, with respect to any related Excluded Information posted on the Certificate Administrator’s
Website, such information was not delivered to the Certificate Administrator in accordance with Section 3.30.


 


Each of the Master Servicer,
the Special Servicer, the Operating Advisor and the Certificate Administrator shall be entitled to conclusively rely on delivery
from the Directing Holder or a Controlling Class Certificateholder of an investor certification substantially in the form of Exhibit
P-1B that it is not or is no longer an Excluded Controlling Class Holder. To the extent the Directing Holder or a Controlling
Class Certificateholder receives access pursuant to this Agreement to any Excluded Information on the Certificate Administrator’s
Website or otherwise receives access to such Excluded Information, such Directing Holder or Controlling Class Certificateholder
shall be deemed to have agreed that it (i) will not directly or indirectly provide any such Excluded Information to (A) the related
Borrower Party, (B) any related Excluded Controlling Class Holder, (C) any employees or personnel of such Directing Holder or Controlling
Class Certificateholder or any of its Affiliate involved in the management of any investment in the related Borrower Party or the
related Mortgaged Property or (D) to its actual knowledge, any non-Affiliate that holds a direct or indirect ownership interest
in the related Borrower Party, and (ii) will maintain sufficient internal controls and appropriate policies and procedures in place
in order to comply with the obligations described in clause (i) above.

Retention Consultation Party or a Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest,
as applicable, receives access pursuant to this Agreement to any information solely related to a Mortgage Loan with respect to
which such party is a Borrower Party (which shall include any Asset Status Reports, Final Asset Status Reports (or summaries thereof)),
inspection reports related to Specially Serviced Loans conducted by the Special Servicer or any Excluded Special Servicer and which
may include any Operating Advisor reports delivered to the Certificate Administrator regarding the Special Servicer’s net
present value determination or any Appraisal Reduction Amount calculations delivered pursuant to Section 3.26(d), and any
Officer’s Certificates delivered by the Trustee, the Master Servicer or the Special Servicer, supporting any determination
that any Advance was (or, if made, would be) a Nonrecoverable Advance, but in each case other than information with respect to
such Mortgage Loan that is aggregated with information of other Mortgage Loans at a pool level), on the Certificate Administrator’s
Website or otherwise receives access to such information, such Risk Retention Consultation Party or Holder of a VRR Interest, a
Y&L Towers VRR Interest or a Standard Highline VRR Interest, as applicable, shall be deemed to have agreed that it (i) will
not directly or indirectly provide any such information to (A) the related Borrower Party, (B) any employees or personnel of such
Risk Retention Consultation Party or Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest,
as applicable or any of its Affiliates involved in the management of any investment in the related Borrower Party or the related
Mortgaged Property or (C) to its actual knowledge, any non-Affiliate that holds a direct or indirect ownership interest in the
related Borrower Party, and (ii) will maintain sufficient internal controls and appropriate policies and procedures in place in
order to comply with the obligations described in clause (i) above. For the avoidance of doubt, any file or report contained
in the CREFC® Investor Reporting Package (CREFC® IRP) (other than the CREFC® Special
Servicer Loan File relating

Mortgage Loans at a pool level.

therefor, other than with respect to such reports, documents or other information prepared by the Certificate Administrator. In
addition, the Certificate Administrator may disclaim responsibility for any information distributed by it or filed by it, as applicable,
for which it is not the original source. Notwithstanding anything herein to the contrary, the Certificate Administrator shall not
be liable for any disclosure of information relating to any Excluded Controlling Class Loan to the extent such information was
included in the Asset Status Report or the Final Asset Status Report delivered to the Certificate Administrator for posting to
the Certificate Administrator’s Website and not properly identified as relating to any Excluded Controlling Class Loan.

Administrator an Opinion of Counsel, addressed to the Trustee and the Certificate Administrator, to the effect that the holding
by the Trust of such REO Property subsequent to the close of the third calendar year following the year in which acquisition occurred
will not cause an Adverse REMIC Event to occur. If the Special Servicer is granted or not denied the REO Extension contemplated
by clause (i) of the immediately preceding sentence or obtains the Opinion of Counsel contemplated by clause (ii)
of the immediately preceding sentence, the Special Servicer shall sell such REO Property within such longer period as is permitted
by such REO Extension or such Opinion of Counsel, as the case may be. Any expense incurred by the Special Servicer in connection
with its being granted the REO Extension contemplated by clause (i) of the second preceding sentence or its obtaining the
Opinion of Counsel contemplated by clause (ii) of the second preceding sentence, shall be an expense of the Trust payable
out of the Collection Account pursuant to Section 3.05(a).


 


(b)         The
Special Servicer shall segregate and hold all funds collected and received in connection with any REO Property separate and apart
from its own funds and general assets. If an REO Acquisition shall occur, the Special Servicer shall establish and maintain one
or more REO Accounts, held on behalf of the Trustee for the benefit of the Certificateholders and, if applicable, on behalf of
any related Companion Holder(s), as applicable, as their interest shall appear, and the Trustee (as holder of the Lower-Tier Regular
Interests), for the retention of revenues and other proceeds derived from each REO Property. The REO Account shall be an Eligible
Account. The Special Servicer shall deposit, or cause to be deposited, in the REO Account, within one (1) Business Day after receipt
of properly identified funds, all REO Revenues, Insurance and Condemnation Proceeds and Liquidation Proceeds received in respect
of an REO Property. Funds in the REO Account may be invested in Permitted Investments in accordance with Section 3.06. The
Special Servicer shall give notice to the Trustee, the Certificate Administrator, and the Master Servicer of the location of the
REO Account when first established and of the new location of the REO Account prior to any change thereof.


 






     -291-


     


    

 


(c)         The
Special Servicer shall withdraw from the REO Account funds necessary for the proper operation, management, insuring, leasing, maintenance
and disposition of any REO Property, but only to the extent of amounts on deposit in the REO Account relating to such REO Property.
On the later of the date that is (x) on or prior to each Determination Date or (y) two (2) Business Days after such amounts are
received and properly identified and determined to be available (or, with respect to a Serviced Companion Loan (other than any
Trust Subordinate Companion Loan), on the Business Day preceding each Serviced Whole Loan Remittance Date), the Special Servicer
shall withdraw from the REO Account and remit to the Master Servicer, which shall deposit into the Collection Account (or the Companion
Distribution Account, as applicable), the aggregate of all amounts received in respect of each REO Property during the one-month
period ending on such Determination Date, net of (i) any withdrawals made out of such amounts pursuant to the preceding sentence
and (ii) Net Investment Earnings on amounts on deposit in the REO Account; provided, however, that the Special Servicer
may retain in such REO Account, in accordance with the Servicing Standard, such portion of such balance as may be necessary to
maintain a reasonable reserve for repairs, replacements, leasing, management and tenant improvements and other related expenses
for the related REO Property. In addition, on or prior to each Determination Date (or with respect to a Serviced Companion Loan,
on the Business Day preceding each Serviced Whole Loan Remittance Date), the Special Servicer shall provide the Master Servicer
with a written accounting of amounts remitted to the Master Servicer for deposit in the Collection Account, as applicable, on such
date. The Master Servicer shall apply all such amounts as instructed by the Special Servicer on the Determination Date (or with
respect to a Serviced Companion Loan, on each Serviced Whole Loan Remittance Date) for the related Distribution Date.


 


(d)         The
Special Servicer shall keep and maintain separate records, on a property-by-property basis, for the purpose of accounting for all
deposits to, and withdrawals from, the REO Account pursuant to Section 3.14(b) or Section 3.14(c).


 


(e)         With
respect to the Trust Subordinate Companion Loans, references to actions being taken for the benefit of any such Companion Loan
in this Section 3.14 shall be deemed to be taken also for the benefit of the Holders of the related Loan-Specific Certificates,
as beneficial owners of such Companion Loan.


 


Section 3.15     Management
of REO Property.  (a) If title to any REO Property is acquired, the Special Servicer shall manage, conserve, protect,
operate and lease such REO Property (other than any Non-Serviced Mortgaged Property) for the benefit of the Certificateholders
and the related Companion Holders, as applicable, and the Trustee (as holder of the Lower-Tier Regular Interests and Trust Subordinate
Companion Loan REMIC Regular Interests) solely for the purpose of its timely disposition and sale in a manner that does not cause
such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code
or result in the receipt by the Trust or any Serviced Companion Noteholder of any “income from non-permitted assets”
within the meaning of Section 860F(a)(2)(B) of the Code or result in an Adverse REMIC Event. Subject to the foregoing, however,
the Special Servicer shall have full power and authority to do any and all things in connection therewith as are in the best interests
of and for the benefit of the Certificateholders (and, in the case of each Serviced Whole Loan, the related Companion Holder(s))
and the Trustee (as holder of the Lower-Tier Regular Interests and the Trust


 



     -292-


     


    

 


Subordinate Companion Loan REMIC Regular Interests)
all as a collective whole (taking into account the subordinate or pari passu nature of any Companion Loan, as the case
may be) (as determined by the Special Servicer in its reasonable judgment in accordance with the Servicing Standard). Notwithstanding
anything to the contrary herein, REO Property with respect to a Non-Serviced Mortgage Loan is excluded for all purposes of this
Section 3.15. Subject to this Section 3.15, the Special Servicer may allow the Trust or any commercial mortgage
securitization that holds any Serviced Companion Loan to earn “net income from foreclosure property” within the meaning
of Section 860G(d) of the Code if it determines that earning such income is in the best interests of Certificateholders and, if
applicable, any related Companion Holder(s) on a net after-tax basis as compared with net leasing such REO Property or operating
such REO Property on a different basis. In connection therewith, the Special Servicer shall deposit or cause to be deposited on
a daily basis (and in no event later than one (1) Business Day following receipt of such properly identified funds) in the applicable
REO Account all revenues received by it with respect to each REO Property and the related REO Loan, and shall withdraw from the
REO Account, to the extent of amounts on deposit therein with respect to such REO Property, funds necessary for the proper operation,
management, leasing and maintenance of such REO Property, including, without limitation:


 


(i)          all
insurance premiums due and payable in respect of such REO Property;


 


(ii)         all
real estate taxes and assessments in respect of such REO Property that may result in the imposition of a lien thereon;


 


(iii)        any
ground rents in respect of such REO Property, if applicable; and


 


(iv)        all
costs and expenses necessary to maintain and lease such REO Property.


 


To the extent that amounts
on deposit in the REO Account in respect of any REO Property are insufficient for the purposes set forth in clauses (i)
through (iv) above with respect to such REO Property, the Master Servicer (subject to receiving notice from the Special
Servicer in accordance with the procedures set forth elsewhere in this Agreement) shall advance from its own funds such amount
as is necessary for such purposes unless (as evidenced by an Officer’s Certificate delivered to the Trustee, the Special
Servicer, the Depositor, the Certificate Administrator and the Directing Holder (with respect to the Directing Holder, in respect
of any Mortgage Loan other than an Excluded Loan as to such party or a Trust Subordinate Companion Loan, and prior to the occurrence
and continuance of a Consultation Termination Event)) such advances would, if made, constitute Nonrecoverable Servicing Advances.


 


(b)         Without
limiting the generality of the foregoing, the Special Servicer shall not:


 


(i)          permit
the Trust to enter into, renew or extend any New Lease with respect to any REO Property, if the New Lease by its terms will give
rise to any income that does not constitute Rents from Real Property;


 


(ii)         permit
any amount to be received or accrued under any New Lease other than amounts that will constitute Rents from Real Property;


 






     -293-


     


    

 


(iii)        authorize
or permit any construction on any REO Property, other than the completion of a building or other improvement thereon, and then
only if more than 10% of the construction of such building or other improvement was completed before default on the related Mortgage
Loan or Trust Subordinate Companion Loan, if applicable, became imminent, all within the meaning of Section 856(e)(4)(B) of the
Code; or


 


(iv)        Directly
Operate, or allow any other Person, other than an Independent Contractor, to Directly Operate, any REO Property on any date more
than ninety (90) days after its acquisition date;


 


unless, in any such case, the Special Servicer
has obtained an Opinion of Counsel (the cost of which shall be paid by the Master Servicer as a Servicing Advance) to the effect
that such action will not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of
Section 860G(a)(8) of the Code at any time that it is held for the benefit of the Trust, in which case the Special Servicer may
take such actions as are specified in such Opinion of Counsel. The Special Servicer shall cause any Mortgaged Property acquired
as an REO Property to be operated and managed in a manner that would, reasonable judgment exercised in accordance with the Servicing
Standard and to the extent commercially feasible, maximize the Trust’s net after-tax proceeds from such property.


 


(c)          The
Special Servicer shall contract with any Independent Contractor for the operation and management of any REO Property within ninety
(90) days of the acquisition date thereof, provided that:


 


(i)          the
terms and conditions of any such contract may not be inconsistent herewith and shall reflect an agreement reached at arm’s
length;


 


(ii)         the
fees of such Independent Contractor (which shall be an expense of the Trust) shall be reasonable and customary in light of the
nature and locality of the Mortgaged Property;


 


(iii)        any
such contract shall require, or shall be administered to require, that the Independent Contractor (A) pay all costs and expenses
incurred in connection with the operation and management of such REO Property, including, without limitation, those listed in subsection
(a) hereof, and (B) remit all related revenues collected (net of its fees and such costs and expenses) to the Special Servicer
upon receipt;


 


(iv)        none
of the provisions of this Section 3.15(c) relating to any such contract or to actions taken through any such Independent
Contractor shall be deemed to relieve the Special Servicer of any of its duties and obligations hereunder with respect to the operation
and management of any such REO Property; and


 


(v)         the
Special Servicer shall be obligated to manage and supervise such Independent Contractor in accordance with the Servicing Standard.


 


The Special Servicer
shall be entitled to enter into any agreement with any Independent Contractor performing services for it related to its duties
and obligations hereunder


 



     -294-


     


    

 


for indemnification of the Special Servicer by such Independent Contractor, and nothing in this Agreement
shall be deemed to limit or modify such indemnification.


 


(d)         When
and as necessary, the Special Servicer shall send to the Trustee, the Certificate Administrator and the Master Servicer a statement
prepared by the Special Servicer setting forth the amount of net income or net loss, as determined for federal income tax purposes,
resulting from the operation and management of a trade or business on, the furnishing or rendering of a non-customary service to
the tenants of, or the receipt of any other amount not constituting Rents from Real Property in respect of, any REO Property in
accordance with Sections 3.15(a) and 3.15(b).


 


Section 3.16      Sale
of Defaulted Loans and REO Properties.(a) (i) Within thirty (30) days after a Defaulted Loan has become
a Specially Serviced Loan, the Special Servicer shall order (but shall not be required to have received) an Appraisal and within
thirty (30) days of receipt of the Appraisal shall determine the fair value of such Defaulted Loan in accordance with the Servicing
Standard; provided, however, that if the Special Servicer is then in the process of obtaining an Appraisal with
respect to the related Mortgaged Property, the Special Servicer shall make its fair value determination as soon as reasonably
practicable (but in any event within thirty (30) days) after its receipt of such an Appraisal. The Special Servicer may, from
time to time, adjust its fair value determination based upon changed circumstances, new information and other relevant factors,
in each instance in accordance with a review of such circumstances and new information in accordance with the Servicing Standard;
provided that the Special Servicer shall promptly notify the Master Servicer in writing of the initial fair value determination
and any adjustment to its fair value determination.


 


(ii)         If
any Mortgage Loan, Serviced Companion Loan subject to an Intercreditor Agreement is a Specially Serviced Loan or to the extent
otherwise required pursuant to the terms of the related Intercreditor Agreement, then the Special Servicer shall promptly notify
in writing the Master Servicer, any related Companion Holder and any related mezzanine lender, as applicable, of any events requiring
notice under the Intercreditor Agreement in accordance with the terms thereof. Thereafter, any related Companion Holder and related
mezzanine lender, as applicable, will, notwithstanding anything in this Section 3.16 to the contrary, have the option to
purchase the related Mortgage Loan and cure defaults relating thereto as and to the extent set forth in the related Intercreditor
Agreement.


 


(iii)        If
any Mortgage Loan not subject to an Intercreditor Agreement becomes a Specially Serviced Loan, or if the related Companion Holder
or related mezzanine lender, as applicable, for any such Mortgage Loan subject to an Intercreditor Agreement has not previously
exercised the option to purchase the Mortgage Loan pursuant to the previous paragraph, the Special Servicer may offer to sell to
any Person any Specially Serviced Loan (to the extent consistent with any related Intercreditor Agreement and Section 3.16(d))
or may offer to purchase any Specially Serviced Loan, if and when the Special Servicer determines, consistent with the Servicing
Standard, that such a sale would be in the best economic interests of the Certificateholders (including the Holders of the Loan-Specific
Certificates) or, if applicable, the Certificateholders and the Serviced Companion Noteholder(s) (as a collective whole as if the
Trust and the Serviced


 



     -295-


     


    

 


Companion Loan Noteholder(s) constituted a single lender), on a net present value basis. In the case of
any Non-Serviced Mortgage Loan, under certain limited circumstances permitted under the related Intercreditor Agreement, to the
extent that such Non-Serviced Mortgage Loan is not sold together with the related Non-Serviced Companion Loan by the applicable
Non-Serviced Special Servicer for the related Non-Serviced Whole Loan, the Special Servicer will be entitled to sell (with the
consent of the Directing Certificateholder and after consulting with the Risk Retention Consultation Party pursuant to Section
6.08(a), in each case, if no Control Termination Event has occurred and is continuing and such Non-Serviced Mortgage Loan is
not an Excluded Loan as to such party) such Non-Serviced Mortgage Loan if it determines in accordance with the Servicing Standard
that such action would be in the best interests of the Certificateholders, and, subject to the terms of the related Intercreditor
Agreement, the Special Servicer shall be entitled to the liquidation fee that the related Non-Serviced Special Servicer would have
otherwise been entitled to in connection with the sale of such Non-Serviced Mortgage Loan. The Special Servicer is required to
give the Trustee, the Certificate Administrator, the Master Servicer, the Operating Advisor (other than in respect of any applicable
Excluded Loan) and the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder and the
Risk Retention Consultation Party, other than in respect of any Excluded Loan as to such party) not less than ten (10) days’
prior written notice of its intention to sell any Defaulted Loan, in which case the Special Servicer is generally required to accept
the highest offer received from any person for such Specially Serviced Loan in an amount at least equal to the outstanding principal
balance plus all accrued and unpaid interest and outstanding costs and expenses and certain other amounts pursuant to this Agreement
(the “Par Purchase Price”) or, at its option, if it has received no offer at least equal to the Par Purchase
Price therefor, purchase such Specially Serviced Loan at such Par Purchase Price.


 


(iv)        (A)
In the case of a Specially Serviced Loan as to which a default has occurred and is continuing, in the absence of any offer at least
equal to the Par Purchase Price pursuant to clause (iii) above (or purchase by the Special Servicer for such price), the
Special Servicer shall solicit offers and, subject to subclause (B) below, may accept the highest offer received from any
Person that is determined by the Special Servicer to be a fair price for such Specially Serviced Loan, if the highest offeror is
a Person other than an Interested Person. In determining whether any offer from a Person other than an Interested Person constitutes
a fair price for any Defaulted Loan or REO Property, the Special Servicer shall take into account (in addition to the results of
any Appraisal, updated Appraisal or narrative appraisal that it may have obtained pursuant to this Agreement within the prior 6
months), among other factors, the period and amount of the occupancy level and physical condition of the related Mortgaged Property
and the state of the local economy. If the offeror is an Interested Person, the Trustee (based upon updated Appraisals ordered
by the Special Servicer and received by the Trustee (or ordered by the Trustee if the Special Servicer or any of its Affiliates
is an Interested Person)) shall determine the fair price unless (i) the offer is equal to or greater than the applicable Par Purchase
Price and (ii) the offer is the highest offer received; provided, however, that no offer from an Interested Person
will constitute a fair price unless (A) it is the highest offer received and (B) if the offer is less than the applicable Par Purchase
Price, at least two other offers are received from independent third parties, and any such determination by the


 



     -296-


     


    

 


Trustee shall be
binding upon all parties. The Trustee shall act in a commercially reasonable manner in making such determination. In determining
whether any offer received from an Interested Person represents a fair price for any such Defaulted Loan, the Trustee shall rely
on the most recent Appraisal (or update of such Appraisal) of the related Mortgaged Property conducted in accordance with this
Agreement within the preceding 6-month period or, in the absence of any such Appraisal, on a new Appraisal. Except as provided
in the following paragraph, the cost of any Appraisal will be covered by, and will be reimbursable as, a Servicing Advance.


 


Notwithstanding
anything contained in the preceding paragraph to the contrary, if the Trustee is required to determine whether a cash offer by
an Interested Person constitutes a fair price and the offer is less than the Par Purchase Price, the Trustee may, at its option,
(at the expense of the Interested Person) designate an independent third party expert in real estate or commercial mortgage loan
matters with at least 5 years’ experience in valuing or investing in loans similar to the subject Mortgage Loan or Serviced
Whole Loan, as the case may be, that has been selected with reasonable care by the Trustee to determine if such cash offer constitutes
a fair price for such Mortgage Loan or Serviced Whole Loan. If the Trustee designates such a third party to make such determination,
the Trustee shall be entitled to rely conclusively upon such third party’s determination. The reasonable fees of, and the
costs of all appraisals, inspection reports and broker opinions of value incurred by any such third party shall be covered by,
and shall be reimbursable, from the offering Interested Person and the Special Servicer shall use efforts consistent with the Servicing
Standard to collect payment from such Interested Person. If such expense is not paid by the applicable Interested Person within
thirty (30) days of demand for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing
Advance (provided that the Trustee shall not engage a third party expert whose fees exceed a commercially reasonable amount
as determined by the Trustee) but the Special Servicer shall continue to use efforts consistent with the Servicing Standard to
collect such amounts from the applicable Interested Person. Neither the Trustee, in its individual capacity, nor any of its Affiliates
may make an offer for or purchase any Specially Serviced Loan.


 


(B)      The
Special Servicer shall not be obligated to accept the highest offer if the Special Servicer determines (in consultation with the
Directing Holder and the Risk Retention Consultation Party, subject to the limitations on consultation set forth in Section
6.08(a) (in each case, unless a Consultation Termination Event shall have occurred and be continuing and other than with respect
to any Mortgage Loan that is an Excluded Loan as to such party) and, in the case of a Serviced Whole Loan or an REO Property related
to a Serviced Whole Loan, the related Companion Holder), in accordance with the Servicing Standard (and subject to the requirements
of any related Intercreditor Agreement), that the rejection of such offer would be in the best interests of the Holders of Certificates
and, in the case of a sale of a Serviced Whole Loan, the related Companion Holder(s) (as a collective whole, as if such Certificateholders
and, if applicable, the related Companion Holder(s) constituted a single lender). In addition, the Special Servicer may accept
a lower offer if it determines, in accordance with the Servicing Standard (and


 



     -297-


     


    

 


subject to the requirements of any related Intercreditor
Agreement), that the acceptance of such offer would be in the best interests of the Holders of Certificates (including the holders
of the Loan-Specific Certificates) and, in the case of a sale of a Serviced Whole Loan, the related Companion Holder(s) (as a collective
whole, as if such Certificateholders and, if applicable, the related Companion Holder constituted a single lender (and with respect
to any AB Whole Loan, taking into account the subordinate nature of the related Subordinate Companion Loan)) (for example, if the
prospective buyer making the lower offer is more likely to perform its obligations, or the terms offered by the prospective buyer
making the lower offer are more favorable); provided that the offeror is not the Special Servicer or a Person that is an
Affiliate of the Special Servicer. The Special Servicer shall use reasonable efforts to sell all Defaulted Loans prior to the Rated
Final Distribution Date. For the avoidance of doubt, the Trustee shall have no obligation to make any fair value determination,
to the extent required to do so pursuant to this Section 3.16, on the basis of anything other than the related Appraisal.


 


(v)         Unless
and until any Specially Serviced Loan is sold pursuant to this Section 3.16(a), the Special Servicer shall pursue such other
resolution strategies with respect to such Specially Serviced Loan, including, without limitation, workout and foreclosure, as
the Special Servicer may deem appropriate, consistent with the Asset Status Report and the Servicing Standard and the REMIC Provisions.


 


(b)         (i)
(A) The Special Servicer may purchase any REO Property at the Par Purchase Price therefor (in the case of a Serviced Whole Loan,
such purchase shall be a purchase of the entire REO Property, including the portion relating to the related Companion Loan). The
Special Servicer may also offer to sell to any Person any REO Property (in the case of a Serviced Whole Loan, such sale shall be
a sale of the entire REO Property, including the portion relating to the related Companion Loan), if and when the Special Servicer
determines, consistent with the Servicing Standard, that such a sale would be in the best economic interest of the Trust and the
related Companion Holders. The Special Servicer shall give the Trustee, the Master Servicer, each Companion Holder, the Certificate
Administrator and the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder and the Risk
Retention Consultation Party, in respect of any Mortgage Loan other than an Excluded Loan as to such party and prior to the occurrence
and continuance of a Consultation Termination Event) not less than ten (10) days’ prior written notice of the Purchase Price
and its intention to (i) purchase any REO Property at the Par Purchase Price therefor or (ii) sell any REO Property, in which case
the Special Servicer shall accept the highest offer received from any Person for any REO Property in an amount at least equal to
the Par Purchase Price therefor. To the extent permitted by applicable law, and subject to the Servicing Standard, the Master Servicer,
an Affiliate of the Master Servicer, the Special Servicer or an Affiliate of the Special Servicer, or an employee of either of
them may act as broker in connection with the sale of any REO Property and may retain from the proceeds of such sale a brokerage
commission that does not exceed the commission that would have been earned by an independent broker pursuant to a brokerage agreement
entered into at arm’s length.


 






     -298-


     


    

 


(B)      In
the absence of any such offer as set forth in subclause (A) above, the Special Servicer shall, subject to subclause (C)
below, accept the highest offer for such REO Property received from any Person that is determined to be a fair price (1) by the
Special Servicer, if the highest offeror is a Person other than an Interested Person, or (2) by the Trustee, if the highest offeror
is an Interested Person unless (i) the offer is equal to or greater than the applicable Purchase Price and (ii) the offer is the
highest offer received; provided, however, that no offer from an Interested Person will constitute a fair price unless
(A) it is the highest offer received and (B) if the offer is less than the applicable Par Purchase Price, at least two other offers
are received from independent third parties. Notwithstanding anything to the contrary herein, neither the Trustee, in its individual
capacity, nor any of its Affiliates may make an offer for or purchase any REO Property pursuant hereto.


 


(C)      The
Special Servicer shall not be obligated by either of the foregoing paragraphs or otherwise to accept the highest offer if the Special
Servicer determines, in accordance with the Servicing Standard, that rejection of such offer would be in the best interests of
the Certificateholders and, with respect to any Serviced Whole Loan or the related Companion Holder, and in either case, as a collective
whole (taking into account the subordinate or pari passu nature of any Serviced Companion Loans). In addition, the Special
Servicer may accept a lower offer if it determines, in accordance with the Servicing Standard, that acceptance of such offer would
be in the best interests of the Certificateholders and, with respect to any Serviced Whole Loan or the related Companion Holder,
and in either case, as a collective whole (taking into account the subordinate or pari passu nature of any Serviced Companion
Loans) (for example, if the prospective buyer making the lower offer is more likely to perform its obligations, or the terms offered
by the prospective buyer making the lower offer are more favorable); provided that the offeror is not the Special Servicer
or a Person that is an Affiliate of the Special Servicer.


 


(D)      In
determining whether any offer received from an Interested Person represents a fair price for any REO Property, the Trustee shall
obtain and may conclusively rely on the opinion of an Independent appraiser or other Independent expert in real estate matters
retained by the Trustee in connection with making such determination. The reasonable cost of such Independent appraiser or other
Independent expert shall be an expense of the offering Interested Person purchaser. The reasonable fees of and the costs of all
appraisals, inspection reports and broker opinions of value incurred by any such third party shall be covered by, and shall be
reimbursable, from the offering Interested Person and the Special Servicer shall use efforts consistent with the Servicing Standard
to collect payment from such Interested Person. If such expense is not paid by the applicable Interested Person within thirty (30)
days of demand for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing Advance but
the Special Servicer shall continue to use efforts consistent with the Servicing Standard to collect such amounts from the applicable
Interested Person. In determining whether any offer


 



     -299-


     


    

 


constitutes a fair price for any REO Property, the Special Servicer or the
Trustee (or, if applicable, such appraiser) shall take into account, and any appraiser or other expert in real estate matters shall
be instructed to take into account, as applicable, among other factors, the physical condition of such REO Property, the state
of the local economy and the Trust’s obligation to comply with REMIC Provisions.


 


(ii)         Subject
to the Servicing Standard, the Special Servicer shall act on behalf of the Trust and the related Companion Holders in negotiating
and taking any other action necessary or appropriate in connection with the sale of any REO Property, including the collection
of all amounts payable in connection therewith. A sale of any REO Property shall be without recourse to, or representation or warranty
by, the Trustee, the Depositor, the Master Servicer, the Special Servicer, the Certificate Administrator, the Operating Advisor
or the Trust (except that any contract of sale and assignment and conveyance documents may contain customary warranties of title,
so long as the only recourse for breach thereof is to the Trust) and, if consummated in accordance with the terms of this Agreement,
none of the Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator, the Operating Advisor nor the
Trustee shall have any liability to the Trust or any Certificateholder or related Companion Holder (if applicable) with respect
to the purchase price therefor accepted by the Special Servicer or the Trustee.


 


(c)         Any
sale of a Defaulted Loan or any REO Property shall be for cash only (unless changes in the REMIC Provisions or authoritative interpretations
thereof made or issued subsequent to the Startup Day allow a sale for other consideration).


 


(d)         With
respect to each Serviced Pari Passu Whole Loan, pursuant to the terms of the related Intercreditor Agreement and this Agreement,
if the related Serviced Pari Passu Whole Loan becomes a Defaulted Loan, and if the Special Servicer determines to sell the related
Mortgage Loan that has become a Defaulted Loan in accordance with this Section 3.16, then the Special Servicer shall sell
the related Serviced Pari Passu Companion Loan (and, in the case of the Yorkshire & Lexington Towers Whole Loan, the Y&L
Towers Trust Subordinate Companion Loan and, in the case of The Standard Highline NYC Whole Loan, the Standard Highline Trust Subordinate
Companion Loan) together with such Mortgage Loan as one whole loan and shall require that all offers be submitted to the Special
Servicer in writing. To the extent a determination is required to be made hereunder as to whether any cash offer constitutes a
fair price for any Serviced Whole Loan, such determination shall be made by the Trustee if the offeror is an Interested Person.
Notwithstanding the foregoing, the Special Servicer shall not be permitted to sell the related Mortgage Loan together with the
related Serviced Pari Passu Companion Loan(s) if it becomes a defaulted Whole Loan without the written consent of the holder of
the related Serviced Pari Passu Companion Loan (provided that such consent is not required if the holder of the Serviced
Pari Passu Companion Loan is the Mortgagor or an affiliate of the Mortgagor) unless the Special Servicer has delivered to the holder
of the related Serviced Pari Passu Companion Loan: (a) at least fifteen (15) Business Days prior written notice of any decision
to attempt to sell such Serviced Whole Loan; (b) at least ten (10) days prior to the permitted sale date, a copy of each bid package
(together with any material amendments to such bid packages) received by the Special Servicer in connection with any such proposed
sale; (c) at least ten (10) days prior to the proposed sale date, a copy of the most recent appraisal for such


 



     -300-


     


    

 


Serviced Pari Passu
Whole Loan, and any documents in the servicing file reasonably requested by the holder of the related Serviced Pari Passu Companion
Loan that are material to the sale price of the Serviced Pari Passu Whole Loan; and (d) until the sale is completed, and a reasonable
period of time (but no less time than is afforded to other offerors and the Directing Certificateholder and the Risk Retention
Consultation Party) prior to the proposed sale date, all information and other documents being provided to other offerors and all
leases or other documents that are approved by the Master Servicer or the Special Servicer in connection with the proposed sale.
The holder of the related Serviced Pari Passu Companion Loan (or its representative) will be permitted to submit an offer at any
sale of such Whole Loan; however, the related Mortgagor and its agents and Affiliates shall not be permitted to submit an
offer at such sale. Notwithstanding the foregoing, with respect to each Serviced Whole Loan, the holder of the related Companion
Loan may waive any of the delivery or timing requirements set forth in this paragraph with respect to the related Whole Loan. If
the Trustee is required to determine whether a cash offer by an Interested Person constitutes a fair price, the Trustee may (at
its option and at the expense of the offering Interested Person purchaser) designate an independent third party expert in real
estate or commercial mortgage loan matters with at least 5 years’ experience in valuing or investing in loans similar to
the subject Mortgage Loan, that has been selected with reasonable care by the Trustee to determine if such cash offer constitutes
a fair price for such Mortgage Loan. The Trustee shall act in a commercially reasonable manner in making such determination. If
the Trustee designates such a third party to make such determination, the Trustee shall be entitled to rely conclusively upon such
third party’s determination. The reasonable fees of, and the costs of all appraisals, inspection reports and broker opinions
of value incurred by any such third party shall be covered by, and shall be reimbursable, from the offering Interested Person and
the Special Servicer shall use efforts consistent with the Servicing Standard to collect payment from such Interested Person. If
such expense is not paid by the applicable Interested Person within thirty (30) days of demand for payment, such expense shall
be reimbursable to the Trustee by the Master Servicer as a Servicing Advance but the Special Servicer shall continue to use efforts
consistent with the Servicing Standard to collect such amounts from the applicable Interested Person.


 


(e)         (i)
Notwithstanding anything in this Section 3.16 to the contrary, (A) pursuant to the terms of the related Intercreditor Agreement,
the holder of the related AB Subordinate Companion Loan (other than with respect to the Trust Subordinate Companion Loans) for
each applicable Serviced Whole Loan and (B) pursuant to Section 3.32 herein, the Holder of the Standard Highline Non-Trust
Junior Subordinate Companion Loan, will have the right to purchase the related Mortgage Loan or related REO Property, as applicable.
Such right of the holder of the AB Subordinate Companion Loan shall be given priority over any provision described in this Section
3.16 as and to the extent set forth in the related Intercreditor Agreement. If the related Mortgage Loan or related REO Property
is purchased by the holder of such AB Subordinate Companion Loan, repurchased by the applicable Mortgage Loan Seller or otherwise
ceases to be subject to this Agreement, the related AB Subordinate Companion Loan (other than a Trust Subordinate Companion Loan
that is not purchased together with such Mortgage Loan) will no longer be subject to this Agreement. If no AB Control Appraisal
Period exists, the Special Servicer may not sell the AB Subordinate Companion Loan without the prior consent of the holder of the
AB Subordinate Companion Loan. If an AB Control Appraisal Period has occurred and is continuing, the Special Servicer has the right
(but not the obligation) to sell the


 



     -301-


     


    

 


AB Subordinate Companion Loan without the consent of the holder of the AB Subordinate Companion
Loan.


 


(ii)         Notwithstanding
anything in this Section 3.16 to the contrary, any mezzanine lender will have the right to purchase the related Mortgage
Loan or REO Property, as applicable, and cure defaults relating thereto, as and to the extent set forth in the related Intercreditor
Agreement.


 


(f)          Unless
otherwise provided in an Intercreditor Agreement the sale of any Mortgage Loan pursuant to this Section 3.16 will be on
a servicing released basis.


 


(g)         In
the event the Master Servicer or the Special Servicer has the right to purchase any Companion Loan on behalf of the Trust pursuant
to the related Intercreditor Agreement, neither the Master Servicer nor the Special Servicer shall exercise such right.


 


Section 3.17     Additional
Obligations of Master Servicer and Special Servicer.   (a) The Master Servicer shall deliver all Compensating
Interest Payments (other than the portion of any Compensating Interest Payment allocated to a Serviced Pari Passu Companion Loan
or Trust Subordinate Companion Loan) to the Certificate Administrator for deposit in the Lower-Tier REMIC Distribution Account
on each P&I Advance Date, without any right of reimbursement therefor. The Master Servicer shall deliver the portion of any
Compensating Interest Payment allocated to a Serviced Pari Passu Companion Loan to the Companion Paying Agent for deposit in the
Companion Distribution Account on each P&I Advance Date, without any right of reimbursement therefor. The Master Servicer
shall deliver the portion of any Compensating Interest Payment allocated to a Trust Subordinate Companion Loan to the Certificate
Administrator for deposit in the applicable Trust Subordinate Companion Loan REMIC Distribution Account on each P&I Advance
Date, without any right of reimbursement therefor.


 


(b)         The
Master Servicer or the Special Servicer, as applicable, shall provide to each Companion Holder any reports or notices required
to be delivered to such Companion Holder pursuant to the related Intercreditor Agreement and the Master Servicer or Special Servicer,
as applicable, shall provide to the Loan-Specific Directing Holder any reports or notices required to be delivered to the holder
of Trust Subordinate Companion Loan pursuant to the related Intercreditor Agreement.


 


(c)         Upon
the determination that a previously made Advance is a Nonrecoverable Advance, to the extent that the reimbursement thereof would
exceed the full amount of the principal portion of general collections on the Mortgage Loans, and with respect to P&I Advances
on a Trust Subordinate Companion Loan, would exceed the full amount of the principal portion of general collections allocated to
the related Trust Subordinate Companion Loan, deposited in the Collection Account and available for distribution on the next Distribution
Date, the Master Servicer or the Trustee, each at its own option and in its sole discretion, as applicable, instead of obtaining
reimbursement for the remaining amount of such Nonrecoverable Advance pursuant to Section 3.05(a)(v) immediately, as an
accommodation may elect to refrain from obtaining such reimbursement for such portion of the Nonrecoverable Advance during the
one month collection period ending on the then-current Determination Date,


 



     -302-


     


    

 


for successive one-month periods for a total period
not to exceed twelve (12) months (provided that, other than in the case of an Excluded Loan with respect to the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, any
such deferral exceeding six (6) months shall require, prior to the occurrence and continuance of any Control Termination Event,
the consent of the Directing Holder), and any election to so defer or not to defer shall be deemed to be in accordance with the
Servicing Standard. If the Master Servicer or the Trustee makes such an election at its sole option and in its sole discretion
to defer reimbursement with respect to all or a portion of a Nonrecoverable Advance (together with interest thereon), then such
Nonrecoverable Advance (together with interest thereon) or portion thereof shall continue to be fully reimbursable in the subsequent
collection period (subject, again, to the same sole option to defer; it is acknowledged that, in such a subsequent period, such
Nonrecoverable Advance shall again be payable first from principal collections as described above prior to payment from
other collections). In connection with a potential election by the Master Servicer or the Trustee to refrain from the reimbursement
of a particular Nonrecoverable Advance or portion thereof during the one month collection period ending on the related Determination
Date for any Distribution Date, the Master Servicer or the Trustee shall further be authorized to wait for principal collections
on the Mortgage Loans or the Trust Subordinate Companion Loans to be received until the end of such collection period before making
its determination of whether to refrain from the reimbursement of a particular Nonrecoverable Advance or portion thereof); provided,
however, that if, at any time the Master Servicer or the Trustee, as applicable, elects, in its sole discretion, not to
refrain from obtaining such reimbursement or otherwise determines that the reimbursement of a Nonrecoverable Advance during a one-month
collection period will exceed the full amount of the principal portion of general collections on the Mortgage Loans deposited in
the Collection Account for such Distribution Date, then the Master Servicer or the Trustee, as applicable, shall use its reasonable
efforts to give the 17g-5 Information Provider fifteen (15) days’ notice of such determination for posting on the 17g-5 Information
Provider’s Website pursuant to Section 3.13(c), unless extraordinary circumstances make such notice impractical. Notwithstanding
the foregoing, failure to give notice as required by the preceding sentence shall in no way affect the Master Servicer’s
or the Trustee’s election whether to refrain from obtaining such reimbursement as described in this Section 3.17(c).
Nothing herein shall give the Master Servicer or the Trustee the right to defer reimbursement of a Nonrecoverable Advance to the
extent of any principal collections then available in the Collection Account pursuant to Section 3.05(a)(v).


 


The foregoing shall not,
however, be construed to limit any liability that may otherwise be imposed on such Person for any failure by such Person to comply
with the conditions to making such an election under Section 3.17 or to comply with the terms of Section 3.17 and
the other provisions of this Agreement that apply once such an election, if any, has been made; provided, however,
that the fact that a decision to recover such Nonrecoverable Advances over time, or not to do so, benefits some classes of Certificateholders
to the detriment of other classes shall not, with respect to the Master Servicer or the Special Servicer, as applicable, constitute
a violation of the Servicing Standard and/or with respect to the Trustee (solely in its capacity as Trustee), constitute a violation
of any fiduciary duty to Certificateholders or any contractual obligation hereunder. If the Master Servicer or the Trustee, as
applicable, determines, in its sole discretion, that its ability to fully recover the Nonrecoverable Advances has been compromised,
then the Master Servicer or the Trustee, as


 



     -303-


     


    

 


applicable, shall be entitled to immediate reimbursement of Nonrecoverable Advances
with interest thereon at the Reimbursement Rate from all amounts in the Collection Account for such Distribution Date (deemed first
from principal and then interest). Any such election by any such party to refrain from reimbursing itself or obtaining reimbursement
for any Nonrecoverable Advance or portion thereof with respect to any one or more collection periods shall not limit the accrual
of interest at the Reimbursement Rate on such Nonrecoverable Advance for the period prior to the actual reimbursement of such Nonrecoverable
Advance. The Master Servicer’s or the Trustee’s, as applicable, agreement to defer reimbursement of such Nonrecoverable
Advances as set forth above is an accommodation to the Certificateholders and shall not be construed as an obligation on the part
of the Master Servicer or the Trustee, as applicable, or a right of the Certificateholders. Nothing herein shall be deemed to create
in the Certificateholders a right to prior payment of distributions over the Master Servicer’s or the Trustee’s, as
applicable, right to reimbursement for Advances (deferred or otherwise) and accrued interest thereon. In all events, the decision
to defer reimbursement or to seek immediate reimbursement of Nonrecoverable Advances shall be deemed to be in accordance with the
Servicing Standard and none of the Master Servicer, the Trustee or the other parties to this Agreement shall have any liability
to one another or to any of the Certificateholders or any of the Companion Holders for any such election that such party makes
as contemplated by Section 3.17 or for any losses, damages or other adverse economic or other effects that may arise from
such an election.


 


The aggregate of any
Excess Prepayment Interest Shortfall with respect to the Mortgage Loans for any Distribution Date will be allocated on such Distribution
Date among each class of Pooled Certificates, pro rata, in accordance with their respective Interest Accrual Amounts for
that Distribution Date. Any Excess Prepayment Interest Shortfall with respect to a Trust Subordinate Companion Loan for any Distribution
Date will be allocated on such Distribution Date to the related Loan-Specific Certificates, pro rata, in accordance with
each Class’s accrued interest. Any Prepayment Interest Excess in respect of a Trust Subordinate Companion Loan shall be paid
to the Master Servicer as additional servicing compensation.


 


(d)         With
respect to any Mortgage Loan (or Serviced Whole Loan), if the related loan documents permit the lender to (but do not require the
lender to), at its option, prior to an event of default under the related Mortgage Loan (or Serviced Whole Loan), apply amounts
held in any reserve account as a prepayment or hold such amounts in a reserve account, the Master Servicer or the Special Servicer,
as the case may be, may not apply such amounts as a prepayment, and will instead continue to hold such amounts in the applicable
reserve account, unless not applying those amounts as a prepayment would be a violation of the Servicing Standard. Such amount
may be used, if permitted under the loan documents, to defease the loan, or may be used to prepay the Mortgage Loan (or Serviced
Whole Loan) or for other purpose consistent with the Servicing Standard and the loan documents, upon a subsequent default.


 


(e)         With
respect to any modification or amendment of any Intercreditor Agreement related to a Serviced Whole Loan (to the extent received),
the Master Servicer or the Special Servicer, as applicable, shall provide to the 17g-5 Information Provider a copy of any such
modification or amendment, which the 17g-5 Information Provider shall promptly post on the 17g-5 Information Provider’s Website
in accordance with Section 3.13(c).

Section 3.18     Modifications,
Waivers, Amendments and Consents.  (a) Except as set forth in Section 3.08(a), Section 3.08(b), this
Section 3.18(a), Section 3.18(d), Section 3.18(h), Section 3.18(i) and Section 6.08, but subject to
any other conditions set forth thereunder (including, without limitation, (i) the Master Servicer’s processing rights pursuant
to this subsection (a) with respect to any modification, waiver or amendment that does not constitute a Major Decision
and (ii) the Special Servicer’s processing rights pursuant to this subsection (a) with respect to any modification,
waiver or amendment that does constitute a Major Decision) and, with respect to any Mortgage Loan (other than any Non-Serviced
Mortgage Loan) or any Serviced Whole Loan, (and with respect to any Serviced Whole Loan, subject to the rights of the related
Companion Holder to advise or consult with the Master Servicer or the Special Servicer, as the case may be, with respect to, or
to consent to, a modification, waiver or amendment, in each case, pursuant to the terms of the related Intercreditor Agreement),
the Master Servicer shall not agree to any modification, waiver or amendment to the terms of a Mortgage Loan and/or Companion
Loan that constitutes a Major Decision; and provided, that no extension entered into pursuant to this Section 3.18(a)
shall extend the Maturity Date beyond the earlier of (i) five (5) years (or, with respect to the Yorkshire & Lexington
Whole Loan or The Standard Highline NYC Whole Loan, seven (7) years) prior to the Rated Final Distribution Date and (ii) in the
case of a Mortgage Loan secured solely or primarily by a leasehold estate and not also the related fee interest, the date twenty
(20) years or, to the extent consistent with the Servicing Standard giving due consideration to the remaining term of the Ground
Lease, ten (10) years, prior to the expiration of such leasehold estate. If such extension would extend the Maturity Date of such
Mortgage Loan and/or related Companion Loan for more than twelve (12) months from and after the original Maturity Date of such
Mortgage Loan and/or related Companion Loan and such Mortgage Loan and/or related Companion Loan is not in default or default
with respect thereto is not reasonably foreseeable, prior to any such extension, (1) the Master Servicer shall provide the Trustee,
the Certificate Administrator, the Special Servicer, the Operating Advisor, the Directing Holder and the Risk Retention Consultation
Party (in the case of the Directing Holder and the Risk Retention Consultation Party, (i) prior to the occurrence and continuance
of a Consultation Termination Event and (ii) other than with respect to any Mortgage Loan that is an Excluded Loan as to such
party), with an Opinion of Counsel (at the expense of the related Mortgagor to the extent permitted under the Mortgage Loan documents
and, if not required or permitted to be paid by the Mortgagor, to be paid as an expense of the Trust in accordance with Section
3.11(d)) that such extension would not constitute a “significant modification” of the Mortgage Loan and/or Serviced
Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b) and (2) subject to the Servicing Standard, the Special
Servicer shall (A) obtain the consent of the Directing Holder and, with respect to Specially Serviced Loans, consult with the
Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case, (i) prior to the occurrence and continuance
of a Control Termination Event and (ii) other than with respect to a Mortgage Loan that is an Excluded Loan as to such party)
or (B) consult with the Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each
case, (i) after the occurrence and during the continuance of a Control Termination Event, but (solely in the case of the Directing
Holder) prior to a Consultation Termination Event and (ii) other than with respect to any Excluded Loan as to such party) (which
consent or consultation shall be coordinated through the Special Servicer). Notwithstanding the foregoing, subject to the rights
of the related Companion Holder to advise the Master Servicer with respect to, or consent to, such


 



     -305-


     


    

 


modification, waiver or amendment
pursuant to the terms of the related Intercreditor Agreement, and subject to the Special Servicer’s processing rights pursuant
to this subsection (a), the Master Servicer, with respect to Non-Specially Serviced Loans, without the consent of or consultation
with the Special Servicer, the Operating Advisor or the Directing Holder, may modify or amend the terms of any Mortgage Loan and/or
related Serviced Companion Loan in order to (i) cure any ambiguity or mistake therein, (ii) correct or supplement any provisions
therein which may be inconsistent with any other provisions therein or correct any error or (iii) enter into any modification,
waiver or amendment that does not constitute a Major Decision; provided that, if the Mortgage Loan (other than any Non-Serviced
Mortgage Loan) and/or related Serviced Companion Loan is not in default or default with respect thereto is not reasonably foreseeable,
such modification or amendment would not be a “significant modification” of the Mortgage Loan and/or related Serviced
Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b).


 


Subject to Section
6.08, applicable law and the Mortgage Loan and/or related Serviced Companion Loan documents, neither the Master Servicer nor
the Special Servicer shall permit the substitution of any Mortgaged Property (or any portion thereof) for one or more other parcels
of real property at any time the Mortgage Loan and/or related Serviced Companion Loan is not in default pursuant to the terms of
the related Mortgage Loan and/or related Serviced Companion Loan documents or default with respect thereto is not reasonably foreseeable
unless (i) the Master Servicer or the Special Servicer, as the case may be, obtains Rating Agency Confirmation from each Rating
Agency (and delivers such Rating Agency Confirmation to the Directing Holder and the Risk Retention Consultation Party, if permitted
by the applicable Rating Agency) and a confirmation of any applicable rating agencies that such action will not result in the downgrade,
withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided
that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25)) and (ii) such substitution would not be a “significant
modification” of the Mortgage Loan and/or related Serviced Companion Loan within the meaning of Treasury Regulations Section
1.860G-2(b) or otherwise cause an Adverse REMIC Event (and the Master Servicer or the Special Servicer, as the case may be, may
obtain and rely upon an Opinion of Counsel (at the expense of the related Mortgagor if not prohibited by the terms of the related
Mortgage Loan documents, and if so prohibited, at the expense of the Trust) with respect thereto).


 


In connection with (i)
the release of a Mortgaged Property (other than any Non-Serviced Mortgaged Property), or any portion of such Mortgaged Property
from the lien of the related Mortgage or (ii) the taking of a Mortgaged Property (other than any Non-Serviced Mortgaged Property),
or any portion of such Mortgaged Property by exercise of the power of eminent domain or condemnation, if the related Mortgage Loan
documents require the Master Servicer or the Special Servicer, as applicable, to calculate (or to approve the calculation of the
related Mortgagor of) the loan-to-value ratio of the remaining Mortgaged Property or Mortgaged Properties or the fair market value
of the real property constituting the remaining Mortgaged Property or Mortgaged Properties, for purposes of REMIC qualification
of the related Mortgage Loan, then such calculation shall, unless then permitted by the REMIC Provisions, exclude the value of
personal property and going concern value, if any, as determined by an appropriate third party.


 






     -306-


     


    

 


If, following any such
release or taking, the loan-to-value ratio as so calculated is greater than 125%, the Master Servicer or the Special Servicer,
as applicable, shall require payment of principal by a “qualified amount” as determined under Revenue Procedure 2010-30
or successor provisions, unless the related Mortgagor provides an Opinion of Counsel that if such amount is not paid the related
Mortgage Loan will not fail to be a Qualified Mortgage.


 


(b)         If
the Special Servicer determines that a modification, waiver or amendment (including, without limitation, the forgiveness or deferral
of interest or principal or the substitution of collateral pursuant to the terms of the Mortgage Loan (other than any Non-Serviced
Mortgage Loan) and/or related Serviced Companion Loan or otherwise, the release of collateral or the pledge of additional collateral)
of the terms of a Specially Serviced Loan with respect to which a payment default or other material default has occurred or a payment
default or other material default is, in the Special Servicer’s judgment, reasonably foreseeable (as evidenced by an Officer’s
Certificate of the Special Servicer), is reasonably likely to produce a greater (or equivalent) recovery on a net present value
basis (the relevant discounting to be performed at the related Mortgage Rate) to the Trust and, if applicable, the related Companion
Holders, as the holders of the related Serviced Companion Loan, than liquidation of such Specially Serviced Loan, then the Special
Servicer may agree to a modification, waiver or amendment of such Specially Serviced Loan, subject to (x) the provisions of this
Section 3.18(b) and Section 3.18(c), (y) the approval of the Directing Holder and consultation with the Risk Retention
Consultation Party (in each case, with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than any Excluded
Loan as to such party, prior to the occurrence and continuance of a Control Termination Event (or after the occurrence and during
the continuance of a Control Termination Event, but prior to a Consultation Termination Event, upon consultation with the Directing
Certificateholder and the Risk Retention Consultation Party, and after the occurrence and during the continuance of a Consultation
Termination Event, upon consultation with the Risk Retention Consultation Party)) as provided in Section 6.08; provided
that with respect to any Pooled Serviced AB Whole Loan, prior to the occurrence and continuance of a related AB Control Appraisal
Period, the approval of the holder of the related AB Subordinate Companion Loan, with respect to the Yorkshire & Lexington
Towers Whole Loan, the Y&L Towers Directing Holder (prior to the related control termination event) or with respect to The
Standard Highline NYC Whole Loan, the Standard Highline Directing Holder (prior to the related control termination event) will
be required to the extent set forth in the related Intercreditor Agreement and the Directing Holder shall have no consent or consultation
rights and the Risk Retention Consultation Party shall have no consultation rights regarding the matter; and (z) additionally,
with respect to a Serviced Whole Loan, the rights of the related Serviced Companion Noteholder or with respect to a Mortgage Loan
(other than any Non-Serviced Mortgage Loan) with mezzanine debt, the rights of the related mezzanine lender, to advise or consult
with the Special Servicer with respect to, or consent to, such modification, waiver or amendment, in each case, pursuant to the
terms of the related Intercreditor Agreement; provided that in the case of any release or substitution of collateral (other
than a defeasance), the Special Servicer shall have obtained an Opinion of Counsel that such release or substitution would not
be a “significant modification” of the Mortgage Loan within the meaning of Treasury Regulations Section 1.860G-2(b)
or otherwise cause an Adverse REMIC Event. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with
respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the
Controlling Class (regardless of whether an Operating Advisor Consultation Event has


 



     -307-


     


    

 


occurred and is continuing), the Special Servicer
shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed
Major Decisions that it is processing or for which its consent is required and consider alternative actions recommended by the
Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting with the
Operating Advisor.


 


The Special Servicer
shall use its reasonable efforts to the extent possible to cause each Specially Serviced Loan to fully amortize prior to the Rated
Final Distribution Date and shall not agree to a modification, waiver or amendment of any term of any Specially Serviced Loan if
such modification, waiver or amendment would (1) extend the maturity date of any such Specially Serviced Loan to a date occurring
later than the earlier of (a) five years (or with respect to the Yorkshire & Lexington Towers Whole Loan or the Standard Highline
NYC Whole Loan, seven years) prior to the Rated Final Distribution Date and (b) if the Specially Serviced Loan is secured solely
or primarily by a leasehold estate and not also the related fee interest, the date occurring twenty (20) years or, subject to (x)
compliance with the Servicing Standard giving due consideration to the remaining term of the ground lease and (y) consultation
rights relating to Major Decisions, ten (10) years prior to the expiration of such leasehold estate (including any options to extend
such leasehold estate exercisable unilaterally by the related Mortgagor), or (2) provide for the deferral of interest unless interest
accrues on the related Mortgage Loan, Trust Subordinate Companion Loan or Serviced Whole Loans generally at the related Mortgage
Rate.


 


(c)         Any
provision of this Section 3.18 to the contrary notwithstanding, except when a Mortgage Loan and/or Companion Loan is in
default or default with respect thereto is reasonably foreseeable, no fee described in this Section 3.18 shall be collected
by any Master Servicer or Special Servicer from a Mortgagor (or on behalf of the Mortgagor) in conjunction with any consent or
any modification, waiver or amendment of a Mortgage Loan or Companion Loan, as applicable (unless the amount thereof is specified
in the related Mortgage Note) if the collection of such fee would cause such consent, modification, waiver or amendment to be a
“significant modification” of the Mortgage Note within the meaning of Treasury Regulations Section 1.860G-2(b).


 


(d)         To
the extent consistent with this Agreement (including, without limitation, Section 3.08(a) and 3.08(b), the first
sentence of Section 3.18(a), and Section 6.08), the Master Servicer (subject to the Special Servicer’s processing
rights pursuant to Section 3.18(a) if any such waiver, modification or amendment constitutes a Major Decision) or the Special
Servicer may, consistent with the Servicing Standard, agree to any waiver, modification or amendment of a Mortgage Loan and/or
Serviced Companion Loan that is not in default or as to which default is not reasonably foreseeable only if the contemplated waiver,
modification or amendment (i) will not be a “significant modification” of the Mortgage Loan within the meaning of Treasury
Regulations Section 1.860G-2(b) and (ii) will not cause an Adverse REMIC Event to occur. In making this determination, the Master
Servicer or Special Servicer may obtain and rely upon (and shall provide to the Trustee and the Certificate Administrator if obtained)
an Opinion of Counsel (at the expense of the related Mortgagor or such other Person requesting such modification or, if such expense
cannot be collected from the related Mortgagor or such other Person, to be paid out of the Collection Account pursuant to Section
3.05(a); provided that the Master Servicer or the Special Servicer, as the case may be, shall use its reasonable efforts
to collect such fee from the Mortgagor or such other Person to the


 



     -308-


     


    

 


extent permitted under the related Mortgage Loan documents).
Notwithstanding the foregoing, neither the Master Servicer nor the Special Servicer may waive the payment of any Yield Maintenance
Charge or the requirement that any prepayment of a Mortgage Loan or Trust Subordinate Companion Loan be made on a Due Date, or
if not made on a Due Date, be accompanied by all interest that would be due on the next Due Date with respect to any Mortgage Loan
or Serviced Companion Loan that is not a Specially Serviced Loan.


 


(e)         Subject
to Section 3.18(c), the Master Servicer and the Special Servicer each may, as a condition to its granting any request by
a Mortgagor for consent, modification (including extensions), waiver or indulgence or any other matter or thing, the granting of
which is within the Master Servicer’s or the Special Servicer’s, as the case may be, discretion pursuant to the terms
of the instruments evidencing or securing the related Mortgage Loan or Companion Loan and is permitted by the terms of this Agreement,
require that such Mortgagor pay to the Master Servicer or the Special Servicer, as the case may be, as additional servicing compensation,
a reasonable or customary fee, for the additional services performed in connection with such request; provided that the
charging of such fee is not a “significant modification” of the Mortgage Loan or Trust Subordinate Companion Loan within
the meaning of Treasury Regulations Section 1.860G-2(b).


 


(f)          All
modifications (including extensions), waivers and amendments of the Mortgage Loans and/or Companion Loans entered into pursuant
to this Section 3.18 shall be in writing, signed by the Master Servicer or the Special Servicer, as the case may be, and
the related Mortgagor (and by any guarantor of the related Mortgage Loan or Trust Subordinate Companion Loan, if such guarantor’s
signature is required by the Special Servicer in accordance with the Servicing Standard).


 


(g)         With
respect to any modification, waiver or amendment with respect to a Specially Serviced Loan, the Special Servicer shall notify the
Master Servicer, the Trustee, the Certificate Administrator, the Operating Advisor (after the occurrence and during the continuance
of an Operating Advisor Consultation Event), the Directing Holder and the Risk Retention Consultation Party (in the case of the
Directing Holder, other than following the occurrence and continuance of a Consultation Termination Event, and in the case of the
Directing Holder or the Risk Retention Consultation Party, other than with respect to any Excluded Loan as to such party), the
applicable Companion Holder (unless, with respect to the holders of a Standard Highline Non-Trust Subordinate Companion Loan, a
Standard Highline Non-Trust Junior Subordinate Companion Loan Control Appraisal Period or a Standard Highline Non-Trust Senior
Subordinate Companion Loan Control Appraisal Period, as applicable, has occurred and is continuing or with respect to the holder
of the Standard Highline Trust Subordinate Companion Loan, a Standard Highline Trust Subordinate Companion Loan Control Termination
Event has occurred and is continuing), the related Mortgage Loan Seller (if such Mortgage Loan Seller is not a Master Servicer
or Sub-Servicer of such Mortgage Loan, the Directing Holder or the Risk Retention Consultation Party) and the 17g-5 Information
Provider (which shall promptly post such notice on the 17g-5 Information Provider’s Website in accordance with Section
3.13(c)) in writing of any modification, waiver or amendment (in each case, after it is finalized and executed) of any term
of any Mortgage Loan or Companion Loan that is modified, waived or amended and the date thereof. With respect to any modification,
waiver or amendment (in each case, after it is finalized and executed) for which it is responsible,


 



     -309-


     


    

 


the Master Servicer shall provide
written notice of any such modification, waiver or amendment to the Trustee, the Certificate Administrator, the Special Servicer
(and the Special Servicer shall forward such notice to the Directing Holder and the Risk Retention Consultation Party (in the case
of the Directing Holder, only prior to the occurrence and continuance of a Consultation Termination Event and in the case of the
Directing Holder or the Risk Retention Consultation Party, other than with respect to an Excluded Loan as to such party), the applicable
Companion Holder, the related Mortgage Loan Seller (so long as such Mortgage Loan Seller is not a Master Servicer or Sub-Servicer
of such Mortgage Loan or the Directing Holder or Risk Retention Consultation Party) and the 17g-5 Information Provider (which shall
promptly post such notice on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)). The party
responsible for delivering notice shall deliver to the Custodian with a copy to the Master Servicer (if such notice is being delivered
by the Special Servicer) for deposit in the related Mortgage File, an original counterpart of the agreement relating to such modification,
waiver or amendment, promptly (and in any event within ten (10) Business Days) following the execution thereof, with a copy to
the applicable Companion Holder, if any. Following receipt of the Master Servicer’s or the Special Servicer’s, as the
case may be, delivery of the aforesaid modification, waiver or amendment to the Certificate Administrator, the Certificate Administrator
shall forward a copy thereof to each Holder of a Certificate (other than the Class Z or Class R Certificates) upon request. With
respect to the processing of any modification, waiver or consent related to any Mortgagor incurring additional debt or mezzanine
debt, the Special Servicer (if the Special Servicer processes such modification, waiver or consent pursuant to Section 3.18(a))
or the Master Servicer (if the Master Servicer processes such modification, waiver or consent pursuant to Section 3.18(a))
shall, on or before the later of (i) 3:00 p.m. on the related P&I Advance Date and (ii) five (5) Business Days immediately
following the Master Servicer or the Special Servicer, as the case may be, obtaining actual knowledge of the incurrence of such
additional debt or mezzanine debt, deliver notice of the Mortgagor’s incurrence of such debt, substantially in the form of
Exhibit KK, to cts.sec.notifications@wellsfargo.com and an Additional Disclosure Notification in the form attached hereto
as Exhibit EE. The notice contemplated in the preceding sentence shall set forth, to the extent the Special Servicer or
Master Servicer, as the case may be, has the requisite information or can reasonably obtain such information, (1) the amount of
additional debt that was incurred in the related Collection Period, (2) the total debt service coverage ratio calculated on the
basis of such Mortgage Loan and additional debt, and (3) the aggregate LTV Ratio calculated on the basis of such Mortgage Loan
and additional debt. In the event that either (i) the CREFC® Investor Reporting Package is amended to include such
information set forth above, in a manner reasonably acceptable to the Master Servicer, the Special Servicer and Certificate Administrator,
as applicable, and the Master Servicer confirms with the Certificate Administrator that such amended CREFC® Investor
Reporting Package enables the Certificate Administrator to include such information on Form 10-D in a manner reasonably acceptable
to the Certificate Administrator, or (ii) the Trust is no longer subject to the Exchange Act, the additional report in the form
of Exhibit KK shall no longer be required hereunder. From time to time, the Master Servicer, the Special Servicer and Certificate
Administrator may agree on a different delivery time and format for the information set forth in this paragraph.


 


(h)         Subject
to the consent rights and processes set forth in Section 6.08 with respect to Major Decisions, the Master Servicer shall process
all defeasance transactions, and shall be entitled to any defeasance fees paid relating thereto (provided, that for the
avoidance of


 



     -310-


     


    

 


doubt, any such defeasance fee shall not include the Special Servicer’s portion of any Modification Fees or
waiver fees in connection with a defeasance that the Special Servicer is entitled to under this Agreement). Notwithstanding the
foregoing, the Master Servicer shall not permit (or, with regard to any Non-Serviced Mortgage Loan, take any act in furtherance
of) the substitution of any Mortgaged Property pursuant to the defeasance provisions of any Mortgage Loan or a Serviced Whole Loan
unless such defeasance complies with Treasury Regulations Section 1.860G-2(a)(8)(ii) and the Master Servicer has received (i) replacement
collateral consisting of government securities within the meaning of Treasury Regulations Section 1.860G-2(a)(8)(ii), which satisfies
the requirements of the applicable Mortgage Loan documents, in an amount sufficient to make all scheduled payments under the related
Mortgage Loan or the Trust Subordinate Companion Loan (or defeased portion thereof) when due, (ii) a certificate of an Independent
certified public accountant to the effect that such substituted property will provide cash flows sufficient to meet all payments
of interest and principal (including payments at maturity) on such Mortgage Loan or Serviced Whole Loan in compliance with the
requirements of the terms of the related Mortgage Loan documents and, if applicable, Companion Loan documents, (iii) one or more
Opinions of Counsel (at the expense of the related Mortgagor) to the effect that the Trustee, on behalf of the Trust, will have
a first priority perfected security interest in such substituted Mortgaged Property; provided, however, that, to
the extent consistent with the related Mortgage Loan documents and, if applicable, Companion Loan documents, the related Mortgagor
shall pay the cost of any such opinion as a condition to granting such defeasance, (iv) to the extent consistent with the related
Mortgage Loan documents and, if applicable, Companion Loan documents, the Mortgagor shall establish a single purpose entity to
act as a successor mortgagor, if so required by the Rating Agencies, (v) to the extent permissible under the related Mortgage Loan
documents and, if applicable, Companion Loan documents, the Master Servicer shall use its reasonable efforts to require the related
Mortgagor to pay all costs of such defeasance, including but not limited to the cost of maintaining any successor mortgagor, and
(vi) to the extent permissible under the Mortgage Loan documents and, if applicable, Companion Loan documents, the Master Servicer
shall obtain, at the expense of the related Mortgagor, Rating Agency Confirmation from each Rating Agency and a confirmation of
any applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current
ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be
considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
pursuant to Section 3.25); provided, further, however, that no such confirmation from any Rating Agency
shall be required to the extent that the Master Servicer has delivered a defeasance certificate substantially in the form of Exhibit
U hereto for any Mortgage Loan or Trust Subordinate Companion Loan that (together with any Mortgage Loans cross-collateralized
with such Mortgage Loans) is: (i) a Mortgage Loan with a Cut-off Date Balance less than $20,000,000, (ii) a Mortgage Loan that
represents less than 5% of the aggregate Cut-off Date Balance of all Mortgage Loans and (iii) a Mortgage Loan that is not one of
the ten largest Mortgage Loans by Stated Principal Balance. Notwithstanding the foregoing, in the event that requiring the Mortgagor
to pay for the items specified in clauses (ii), (iv) and (v) in the preceding sentence would be inconsistent
with the related Mortgage Loan documents, such reasonable costs shall be paid by the related Mortgage Loan Seller as and to the
extent set forth in the applicable Mortgage Loan Purchase Agreement.


 



     -311-


     


    

 






 


(i)          Notwithstanding anything herein or in the related Mortgage Loan documents and, if applicable, Companion Loan documents,
to the contrary, the Master Servicer may permit the substitution of “government securities,” within the meaning of
Section 2(a)(16) of the Investment Company Act of 1940, that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii) for
any Mortgaged Property pursuant to the defeasance provisions of any Mortgage Loan or a Serviced Whole Loan, as applicable (or any
portion thereof), in lieu of the defeasance collateral specified in the related Mortgage Loan documents or Serviced Whole Loan
documents, as applicable; provided that such substitution is consistent with the Servicing Standard and the Master Servicer
(subject to the Special Servicer’s consent rights pursuant to Section 3.18(a) with respect to any such action
that constitutes a Major Decision) reasonably determines that allowing their use would not cause a default or event of default
to become reasonably foreseeable and the Master Servicer receives an Opinion of Counsel (at the expense of the Mortgagor to the
extent permitted under the Mortgage Loan documents and, if applicable, Companion Loan documents or otherwise as a Trust Fund expense)
to the effect that such use would not be and would not constitute a “significant modification” of such Mortgage Loan
or Companion Loan pursuant to Treasury Regulations Section 1.860G-2(b) and would not otherwise constitute an Adverse REMIC
Event with respect to any Trust REMIC; and provided, further, that the requirements set forth in Section 3.18(h)
(including receipt of any Rating Agency Confirmation) are satisfied; and provided, further, that such securities
are backed by the full faith and credit of the United States government, or the Master Servicer shall obtain Rating Agency Confirmation
from each Rating Agency and a confirmation of any applicable rating agencies that such action will not result in the downgrade,
withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided
that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25). Notwithstanding the foregoing, with respect to
certain Mortgage Loans originated or acquired by BSP, BSPRT, Column or NREC that are subject to defeasance and identified on Schedule
3, BSP, BSPRT, Column or NREC, as applicable, has transferred to a third party or has retained on behalf of itself or its Affiliate
the right to establish or designate the successor borrower and/or to purchase or cause to be purchased the related defeasance collateral
(collectively, the “Loan Seller Defeasance Rights and Obligations”). In the event the Master Servicer receives
notice of a defeasance request with respect to a Mortgage Loan that provides for Loan Seller Defeasance Rights and Obligations
in the related Mortgage Loan Documents, the Master Servicer shall provide, within five (5) business days of receipt of such notice,
written notice of such defeasance request to the related Mortgage Loan Seller. Until such time as the related Mortgage Loan Seller
provides written notice to the contrary, notice of a defeasance of a Mortgage Loan with Loan Seller Defeasance Rights and Obligations
shall be delivered to the related Mortgage Loan Seller, as applicable, pursuant to the notice provisions hereof. If the successor
borrower is not designated or formed by BSP, BSPRT or Column, as the case may be, or any Affiliate or successor thereto, the successor
borrower shall be reasonably acceptable to the Master Servicer in accordance with the Servicing Standard.


 


(j)          If required under the related Mortgage Loan or Companion Loan documents or if otherwise consistent with the Servicing Standard,
the Master Servicer shall establish and maintain one or more accounts (the “Defeasance Accounts”), which shall
be Eligible Accounts, into which all payments received by the Master Servicer from any defeasance collateral substituted for any
Mortgaged Property shall be deposited and retained, and shall


 






     -312-


     


    

 


administer
such Defeasance Accounts in accordance with the Mortgage Loan or Companion Loan documents. Notwithstanding the foregoing, in no
event shall the Master Servicer permit such amounts to be maintained in the Defeasance Account for a period in excess of ninety
(90) days, unless such amounts are reinvested by the Master Servicer in “government securities,” within the meaning
of Section 2(a)(16) of the Investment Company Act of 1940, that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii).
To the extent not required or permitted to be placed in a separate account, the Master Servicer shall deposit all payments received
by it from defeasance collateral substituted for any Mortgaged Property into the Collection Account and treat any such payments
as payments made on the Mortgage Loan or Companion Loan in advance of its Due Date in accordance with clause (a)(i)
of the definition of “Pooled Available Funds”, clause (a)(i) of the definition of “Y&L Towers Trust
Subordinate Companion Loan Available Funds” or clause (a)(i) of the definition of the “Standard Highline Trust
Subordinate Companion Loan Available Funds”, as applicable and not as a prepayment of the related Mortgage Loan or Companion
Loan. Notwithstanding anything herein to the contrary, in no event shall the Master Servicer permit such amounts to be maintained
in the Collection Account for a period in excess of 365 days (or 366 days in the case of a leap year).


 


(k)         Notwithstanding anything to the contrary in this Agreement, neither the Master Servicer nor the Special Servicer, as applicable,
shall, unless it has received Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced
Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same
manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25)
(the cost of which shall be paid by the related Mortgagor, if so allowed by the terms of the related loan documents and otherwise
paid out of general collections) grant or accept any consent, approval or direction regarding the termination of the related property
manager or the designation of any replacement property manager, with respect to any Mortgaged Property that secures a Mortgage
Loan that (i) is one of the ten largest Mortgage Loans by Stated Principal Balance, (ii) has an unpaid principal balance
that is at least equal to five percent (5%) of the then-aggregate principal balance of all Mortgage Loans or $35,000,000 or (iii) is
the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan.


 


(l)          Notwithstanding anything to the contrary in this Agreement, in connection with any modification, waiver, consent or amendment
in connection with any defeasance transaction contemplated in clause (v)(iii) in the definition of “Major Decision”,
the Master Servicer or the Special Servicer, as applicable, shall not approve any such modification, waiver or amendment or consent
thereto without first having received a copy of an Opinion of Counsel addressed to the Master Servicer and the Special Servicer
that such modification, waiver, consent or amendment will not cause an Adverse REMIC Event.


 


Section 3.19       
Transfer of Servicing Between Master Servicer and Special Servicer; Recordkeeping; Asset Status Report. (a)  Upon
determining that a Servicing Transfer Event has occurred with respect to any Mortgage Loan (other than any Non-Serviced Mortgage
Loan) or Serviced Companion Loan, the Master Servicer or the Special Servicer, as the case may be, shall promptly give notice to
the Master Servicer or the Special Servicer, as the case may be, the Operating Advisor and the Directing Holder (in the case of
the Directing Holder, (i) prior to


 






     -313-


     


    

 


the
occurrence and continuance of a Consultation Termination Event and (ii) other than with respect to any Excluded Loan as to such
party) thereof, and the Master Servicer shall deliver the related Mortgage File and Servicing File to the Special Servicer and
concurrently provide a copy of such Servicing File, exclusive of all Privileged Communications, to the Operating Advisor. The
Master Servicer shall use its reasonable efforts to provide the Special Servicer with all information, documents and records (including
records stored electronically on computer tapes, magnetic discs and the like) relating to such Mortgage Loan and, if applicable,
the related Serviced Companion Loan, either in the Master Servicer’s possession or otherwise available to the Master Servicer
without undue burden or expense, and reasonably requested by the Special Servicer to enable it to assume its functions hereunder
with respect thereto. The Master Servicer shall use its reasonable efforts to comply with the preceding sentence within five (5)
Business Days of the occurrence of each related Servicing Transfer Event (or, in the case of clauses (viii), (ix)
or (x) of the definition of Servicing Transfer Event, within five (5) Business Days of receiving notice from the Special
Servicer of such Servicing Transfer Event when the Special Servicer makes the determination) and in any event shall continue to
act as Master Servicer and administrator of such Mortgage Loan and, if applicable, the related Serviced Companion Loan until the
Special Servicer has commenced the servicing of such Mortgage Loan and, if applicable, the related Serviced Companion Loan. The
Master Servicer shall deliver to the Trustee, the Certificate Administrator, the Operating Advisor, the Directing Holder (other
than with respect to any Excluded Loan as to such party and with respect to the Directing Certificateholder, prior to the occurrence
and continuance of a Consultation Termination Event), a copy of the notice of such Servicing Transfer Event provided by the Master
Servicer to the Special Servicer, or by the Special Servicer to the Master Servicer, pursuant to this Section 3.19.
Prior to the occurrence and continuance of a Consultation Termination Event, the Certificate Administrator shall deliver to each
Controlling Class Certificateholder a copy of the notice of such Servicing Transfer Event provided by the Master Servicer
pursuant to this Section 3.19.


 


Upon determining that a Specially
Serviced Loan (other than an REO Loan) has become current and has remained current for three consecutive Periodic Payments (provided
that (i) no additional Servicing Transfer Event is foreseeable in the reasonable judgment of the Special Servicer, and (ii) for
such purposes taking into account any modification or amendment of such Mortgage Loan and, if applicable, the related Companion
Loan), and that no other Servicing Transfer Event is continuing with respect thereto, the Special Servicer shall immediately give
notice thereof to the Master Servicer, the Operating Advisor, the related Serviced Companion Noteholder (unless, with respect to
the Y&L Towers Trust Subordinate Companion Loan, a Y&L Towers Trust Subordinate Companion Loan Control Termination Event
has occurred or with respect to the Standard Highline Trust Subordinate Companion Loan a Standard Highline Trust Subordinate Companion
Loan Control Termination Event has occurred) and the Directing Holder (other than with respect to any Excluded Loan as to such
party and with respect to the Directing Certificateholder, prior to the occurrence and continuance of a Consultation Termination
Event) and shall return the related Mortgage File and Servicing File to the Master Servicer (or copies thereof if copies only were
delivered to the Special Servicer) and upon giving such notice, and returning such Mortgage File and Servicing File to the Master
Servicer, the Special Servicer’s obligation to service such Corrected Loan shall terminate and the obligations of the Master
Servicer to service and administer such Mortgage Loan and, if applicable, the related Companion Loan shall recommence.


 



     -314-


     


    




 


(b)         In servicing any Specially Serviced Loans and Serviced Companion Loans, the Special Servicer will provide to the Custodian
originals of documents included within the definition of “Mortgage File” for inclusion in the related Mortgage File
to the extent within its possession (with a copy of each such original to the Master Servicer), and provide the Master Servicer
with copies of any additional related Mortgage Loan or Serviced Companion Loan information including correspondence with the related
Mortgagor.


 


(c)         Notwithstanding the provisions of Section 3.12(c), the Master Servicer shall maintain ongoing payment records
with respect to each of the applicable Specially Serviced Loans, Serviced Companion Loans and REO Properties (other than with respect
to a Non-Serviced Mortgage Loan) and shall provide the Special Servicer with any information in its possession with respect to
such records to enable the Special Servicer to perform its duties under this Agreement; provided that this statement shall
not be construed to require the Master Servicer to produce any additional reports.


 


(d)         No later than (i) sixty (60) days after a Servicing Transfer Event for a Mortgage Loan (other than a Non-Serviced Mortgage
Loan) or a Trust Subordinate Companion Loan and, if applicable, any related Companion Loan (in the event any Serviced Whole Loan
becomes a Specially Serviced Loan) and (ii) prior to taking action with respect to any Major Decision (or making a determination
not to take action with respect to a Major Decision) with respect to a Specially Serviced Loan, the Special Servicer shall deliver
in electronic format a report (the “Asset Status Report”) with respect to such Mortgage Loan and related Companion
Loan and the related Mortgaged Property (the “Initial Delivery Date”) and will be required to prepare one or
more additional Asset Status Reports with respect to any such Specially Serviced Loan subsequent to the issuance of a Final Asset
Status Report to the extent that during the course of the resolution of such Specially Serviced Loan changes in strategy reflected
in the initial Asset Status Report (or subsequent Final Asset Status Report) are necessary to reflect the then-current recommendation
as to how the Specially Serviced Loan might be returned to performing status or otherwise liquidated in accordance with the Servicing
Standard (each such report a “Subsequent Asset Status Report”). Each Asset Status Report shall be delivered
in electronic form to the Master Servicer, the Directing Holder (but only with respect to any Mortgage Loan or Trust Subordinate
Companion Loan other than an Excluded Loan as to such party and prior to the occurrence and continuance of a Consultation Termination
Event), the Risk Retention Consultation Party (but only with respect to any Mortgage Loan other than an Excluded Loan as to such
party and other than with respect to the Yorkshire & Lexington Towers Mortgage Loan or The Standard Highline NYC Mortgage Loan),
the Operating Advisor (but other than with respect to an Excluded Loan, only after the occurrence and continuance of an Operating
Advisor Consultation Event), and the 17g-5 Information Provider (which shall promptly post such report on the 17g-5 Information
Provider’s Website in accordance with Section 3.13(c)) and, with respect to any related Serviced Companion Loan,
to the extent the related Serviced Companion Loan has been included in an Other Securitization, to the master servicer of such
Other Securitization into which the related Serviced Companion Loan has been sold or to the related Companion Holder. The Special
Servicer shall notify the Operating Advisor of whether any Asset Status Report delivered to the Operating Advisor is a Final Asset
Status Report, which notification may be satisfied by (i) delivery of an Asset Status Report that is either signed by the Directing
Holder or that otherwise includes an indication that such Asset Status Report is deemed approved due to the passage of any required
consent or consultation


 






     -315-


     


    

 


time
period or (ii) such other method as reasonably agreed to by the Operating Advisor and the Special Servicer. Such Asset Status
Report shall set forth the following information to the extent reasonably determinable based on the information that was delivered
to the Special Servicer in connection with the transfer of servicing pursuant to the Servicing Transfer Event:


 


(i)            a summary of the status of such Specially Serviced Loan and any negotiations with the related Mortgagor;


 


(ii)           a discussion of the legal and environmental considerations reasonably known to the Special Servicer, consistent with the
Servicing Standard, that are applicable to the exercise of remedies as aforesaid and to the enforcement of any related guaranties
or other collateral for the related Specially Serviced Loan and whether outside legal counsel has been retained;


 


(iii)          the most current rent roll (or, with respect to any residential cooperative property, the most current maintenance schedule)
and income or operating statement available for the related Mortgaged Property;


 


(iv)          (A) the Special Servicer’s recommendations on how such Specially Serviced Loan might be returned to performing status
(including the modification of a monetary term, and any workout, restructure or debt forgiveness) and returned to the Master Servicer
for regular servicing or otherwise realized upon (including any proposed sale of a Defaulted Loan or REO Property), (B) a description
of any such proposed or taken actions, and (C) the alternative courses of action that were or are being considered by the Special
Servicer in connection with the proposed or taken actions;


 


(v)           the status of any foreclosure actions or other proceedings undertaken with respect to the Specially Serviced Loan, any proposed
workouts and the status of any negotiations with respect to such workouts, and an assessment of the likelihood of additional defaults
under the related Mortgage Loan or Serviced Whole Loan;


 


(vi)          a description of any amendment, modification or waiver of a material term of any ground lease (or any space lease or air
rights lease, if applicable) or franchise agreement;


 


(vii)         the decision that the Special Servicer made, or intends or proposes to make, including a narrative analysis setting forth
the Special Servicer’s rationale for its proposed decision, including its rejection of the alternatives;


 


(viii)        an analysis of whether or not taking such proposed action is reasonably likely to produce a greater recovery on a present
value basis than not taking such action, setting forth (x) the basis on which the Special Servicer made such determination
and (y) the net present value calculation and all related assumptions;


 


(ix)           the appraised value of the related Mortgaged Property (and a copy of the last obtained Appraisal of such Mortgaged Property)
together with a description of any adjustments to the valuation of such Mortgaged Property made by the Special Servicer together
with an explanation of those adjustments; and


 






     -316-


     


    

 


(x)           such other information as the Special Servicer deems relevant in light of the Servicing Standard.


 


A summary of each Asset Status
Report shall be provided to the Certificate Administrator and the Trustee.


 


If within ten (10) Business Days
of receiving an Asset Status Report, the Directing Holder does not disapprove such Asset Status Report in writing or if the Special
Servicer makes a determination, in accordance with the Servicing Standard that the disapproval by the Directing Holder (communicated
to the Special Servicer within ten (10) Business Days) is not in the best interest of all the Certificateholders), the Special
Servicer shall implement the recommended action as outlined in such Asset Status Report; provided, however, that
the Special Servicer may not take any action that is contrary to applicable law, the Servicing Standard or the terms of the applicable
Mortgage Loan documents. If, with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than an Excluded Loan
with respect to the Directing Holder or the Holder of the majority of the Controlling Class prior to the occurrence and continuance
of any Control Termination Event, the Directing Holder disapproves such Asset Status Report within ten (10) Business Days of receipt
and the Special Servicer has not made the affirmative determination described above, the Special Servicer shall revise such Asset
Status Report and deliver a new Asset Status Report as soon as practicable, but in no event later than thirty (30) days after such
disapproval, to the Master Servicer, the Directing Holder (prior to the occurrence and continuance of a Consultation Termination
Event and other than if an Excluded Loan as to such party is involved), the Operating Advisor (but only after the occurrence and
during the continuance of an Operating Advisor Consultation Event) and the 17g-5 Information Provider (which shall promptly post
such report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)) and, in the case
of a Serviced Whole Loan, the related Serviced Companion Noteholder. With respect to any Mortgage Loan or Trust Subordinate Companion
Loan other than an Excluded Loan with respect to the Directing Holder or the Holder of the majority of the Controlling Class, prior
to the occurrence and continuance of any Control Termination Event, the Special Servicer shall revise such Asset Status Report
as described above in this Section 3.19(d) until the Directing Holder shall fail to disapprove such revised Asset Status
Report in writing within ten (10) Business Days of receiving such revised Asset Status Report or until the Special Servicer makes
a determination, in accordance with the Servicing Standard, that the disapproval is not in the best interests of the Certificateholders;
provided that, if the Directing Holder has not approved the Asset Status Report for a period of sixty (60) Business Days
following the first submission of an Asset Status Report, the Special Servicer may act upon the most recently submitted form of
Asset Status Report, if consistent with the Servicing Standard; provided, however, that such Asset Status Report
does not, and is not intended to be, a substitute for the approvals that are specifically required pursuant to Section 6.08.
The procedures described in this paragraph are collectively referred to as the “Directing Holder Approval Process”.
The Special Servicer may, from time to time, modify any Asset Status Report it has previously delivered and implement such report;
provided that such report shall have been prepared, reviewed and not rejected pursuant to the terms of this Section 3.19(d).
Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Holder or the
Holder of the majority of the Controlling Class (regardless of whether an Operating Advisor Consultation Event has occurred and
is continuing), the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in


 






     -317-


     


    

 


connection
with an Asset Status Report for an Excluded Loan with respect to the Directing Holder or the Holder of the majority of the Controlling
Class that includes a Major Decision that it is processing or for which its consent is required and consider alternative actions
recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08
for consulting with the Operating Advisor.


 


No direction or disapproval of
the Directing Holder hereunder or under a related Intercreditor Agreement or failure of the Directing Holder to consent to or approve
(including any deemed consents or approvals) any request of the Special Servicer, shall (a) require or cause the Special Servicer
to violate the terms of a Specially Serviced Loan, applicable law or any provision of this Agreement, including the Special Servicer’s
obligation to act in accordance with the Servicing Standard and to maintain the REMIC status of each Trust REMIC and the grantor
trust status of the Grantor Trust, (b) result in the imposition of a “prohibited transaction” or “prohibited
contribution” tax under the REMIC Provisions, (c) expose the Master Servicer, the Special Servicer, the Depositor, the
Operating Advisor, the Mortgage Loan Sellers, the Trust, the Trustee, the Certificate Administrator or their respective officers,
directors, members, employees or agents to any claim, suit or liability or (d) materially expand the scope of the Special
Servicer’s, Trustee’s or the Master Servicer’s responsibilities under this Agreement.


 


Prior to an Operating Advisor
Consultation Event, the Special Servicer will be required to deliver each Final Asset Status Report to the Operating Advisor after
the completion of the Directing Holder Approval Process.


 


During the continuance of an
Operating Advisor Consultation Event, the Operating Advisor shall provide comments to the Special Servicer in respect of the applicable
Asset Status Report, if any, within ten (10) Business Days following the later of (i) receipt of such Asset Status Report
or (ii) receipt of such additional information reasonably requested by the Operating Advisor related thereto, and propose
possible alternative courses of action to the extent it determines such alternatives to be in the best interest of the Certificateholders
(including any Certificateholders that are holders of the Controlling Class Certificates), as a collective whole. The Special
Servicer shall consider such alternative courses of action, if any, and any other feedback provided by the Operating Advisor (and
for so long as no Consultation Termination Event is continuing, the Directing Holder) in connection with the Special Servicer’s
preparation of any Asset Status Report that is provided while an Operating Advisor Consultation Event has occurred and is continuing.
The Special Servicer may revise the Asset Status Report as it deems necessary to take into account any input and/or comments from
the Operating Advisor (and for so long as no Consultation Termination Event is continuing, the Directing Holder), to the extent
the Special Servicer determines that the Operating Advisor’s and/or Directing Holder’s input and/or recommendations
are consistent with the Servicing Standard and in the best interest of the Certificateholders as a collective whole (or, with respect
to a Serviced Whole Loan, the best interest of the Certificateholders and the holders of the related Companion Loan(s), as a collective
whole (taking into account the pari passu or subordinate nature of each such Companion Loan)). Promptly upon determining
whether or not to revise any Asset Status Report to take into account any input and/or comments from the Operating Advisor or the
Directing Holder, the Special Servicer shall deliver to the Operating Advisor and the Directing Holder the revised Asset Status
Report (until a Final Asset Status Report is issued). The


 






     -318-


     


    

 


procedures
described in this paragraph are collectively referred to as the “ASR Consultation Process”.


 


After the occurrence and during
the continuance of a Control Termination Event (and at any time with respect to any Excluded Loan with respect to such party or
the Holder of the majority of the Controlling Class), the Directing Holder shall have no right to consent to any Asset Status Report
under this Section 3.19. After the occurrence and during the continuance of a Control Termination Event but prior to
the occurrence and continuance of a Consultation Termination Event, the Special Servicer shall send the Directing Holder (except
with respect to any Excluded Loan as to such party), and, after the occurrence and during the continuance of an Operating Advisor
Consultation Event, the Operating Advisor, the Asset Status Report and the Operating Advisor and the Directing Holder shall consult
with the Special Servicer and propose alternative courses of action and provide other feedback in respect of any Asset Status Report.
The Directing Holder (or, if the Directing Holder is the Directing Certificateholder, other than in its capacity as a Certificateholder)
(in each case, after the occurrence and during the continuance of a Consultation Termination Event (and at any time with respect
to any Excluded Loan as to such party)), shall have no right to receive any Asset Status Report or otherwise consult with the Special
Servicer with respect to Asset Status Reports and the Special Servicer shall only be obligated to consult with the Operating Advisor
with respect to any Asset Status Report as described above. The Special Servicer may choose to revise the Asset Status Report as
it deems reasonably necessary in accordance with the Servicing Standard to take into account any input and/or recommendations of
the Operating Advisor or the Directing Holder during the applicable periods described above, but is under no obligation to follow
any particular recommendation of the Operating Advisor or the Directing Holder.


 


The Special Servicer shall implement
the Final Asset Status Report; provided, however, that the Special Servicer may not take any action that is contrary
to applicable law, the Servicing Standard or the terms of the applicable Mortgage Loan documents.


 


Notwithstanding anything to the
contrary herein, the Directing Holder shall not have any consultation or approval rights with respect to an Asset Status Report
that relates to an Excluded Loan.


 


Notwithstanding the foregoing,
the Special Servicer shall not be permitted to follow any advice, direction or consultation provided by the Operating Advisor,
any Serviced Companion Noteholder (or its representative) or the Directing Certificateholder that would require or cause the Special
Servicer to violate any applicable law, be inconsistent with the Servicing Standard or any Intercreditor Agreement, require or
cause the Special Servicer to violate provisions of this Agreement, require or cause the Special Servicer to violate the terms
of any Intercreditor Agreement or any Mortgage Loan or Serviced Whole Loan, expose any Certificateholder or any party to this Agreement
or their affiliates, officers, directors or agents to any claim, suit or liability, cause any Trust REMIC to fail to qualify as
a REMIC for federal income tax purposes or result in the imposition of “prohibited transaction” or “prohibited
contribution” tax under the REMIC Provisions, or materially expand the scope of the Special Servicer’s responsibilities
under this Agreement or any Intercreditor Agreement.

(e)         (i)  Upon receiving notice of the occurrence of the events described in clause (viii) of the definition
of Servicing Transfer Event (without regard to the 30-day period, respectively, set forth therein), the Master Servicer shall with
reasonable promptness give notice thereof, and shall use its reasonable efforts to provide the Special Servicer with all information
that the Master Servicer has in its possession relating to the Mortgage Loan or Serviced Companion Loan and reasonably requested
by the Special Servicer to enable it to negotiate with the related Mortgagor. The Master Servicer shall use its reasonable efforts
to comply with the preceding sentence within five (5) Business Days of the occurrence of each such event.


 


(ii)           After the occurrence and during the continuance of a Control Termination Event, upon receiving notice of the occurrence
of an event described in clause (viii) of the definition of Servicing Transfer Event (without regard to the 30-day
period set forth therein), the Master Servicer shall deliver notice thereof to the Operating Advisor at the same time such notice
is provided to the Special Servicer pursuant to clause (i) above.


 


(f)          Prior to the occurrence and continuance of a Control Termination Event, no later than two (2) Business Days following the
establishment of a Final Asset Status Report with respect to any Specially Serviced Loan (other than any Excluded Loan), the Special
Servicer shall deliver in electronic format to the Directing Certificateholder (other than with respect to any Excluded Loan as
to such party) a draft notice that will include a draft summary of the Final Asset Status Report (which briefly summarizes such
Final Asset Status Report, but shall not include any Privileged Information) (and shall deliver each Asset Status Report with respect
to a Pooled Serviced AB Whole Loan prior to the occurrence and continuance of an AB Control Appraisal Period (to the extent approved
by the related AB Whole Loan Controlling Holder)). With respect to any Mortgage Loan or Trust Subordinate Companion Loan other
than an Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, if,
prior to the occurrence and continuance of a Control Termination Event, within five (5) Business Days of receipt of such draft
summary, the Directing Certificateholder approves of, or does not disapprove of such draft summary, then the Special Servicer shall
deliver in electronic format such notice and summary of the Final Asset Status Report to the Certificate Administrator for posting
on the Certificate Administrator’s Website pursuant to Section 3.13(b). If the Directing Certificateholder affirmatively
disapproves of such summary in writing, then within two (2) Business Days of receipt of such disapproval, the Special Servicer
shall revise the summary and deliver such new summary to the Directing Certificateholder until the Directing Certificateholder
approves such draft summary; provided, however, that if the Directing Certificateholder has not approved of the draft
summary of the Final Asset Status Report within twenty (20) Business Days of receipt of the initial draft summary of the Final
Asset Status Report, then the most recent draft summary of the Final Asset Status Report delivered by the Special Servicer prior
to such 20th Business Day shall be deemed to be the final summary of the Final Asset Status Report; provided, further,
however, that if at any time the Special Servicer determines that any affirmative disapproval of such draft summary by the
Directing Certificateholder is not in the best interest of all the Certificateholders pursuant to the Servicing Standard, the Special
Servicer shall deliver in electronic format such notice and summary of the Final Asset Status Report to the Certificate Administrator
for posting on the Certificate Administrator’s Website pursuant to Section 3.13(b) notwithstanding such disapproval.
The Special Servicer shall promptly deliver (but in any event no later than two (2) Business Days following its completion) a copy

Loan for which the related holder of an AB Subordinate Companion Loan is not subject to an AB Control Appraisal Period, which
Final Asset Status Report has been approved or deemed approved by the holder of the related AB Subordinate Companion Loan in accordance
with the related Co-Lender Agreement (to the extent such Co-Lender Agreement requires such approval or deemed approval), and deliver
in electronic format notice of such Final Asset Status Report and the summary of such Final Asset Status Report to the Certificate
Administrator for posting on the Certificate Administrator’s Website pursuant to Section 3.13(b).


 


(g)         No provision of this Section 3.19 shall require the Special Servicer to take or to refrain from taking any action
because of any proposal, objection or comment by the Operating Advisor or, after the occurrence and during the continuance of a
Control Termination Event, the Directing Holder or a recommendation of the Operating Advisor or, after the occurrence and during
the continuance of a Control Termination Event, or the Directing Holder.


 


Section 3.20       
Sub-Servicing Agreements. (a)  The Master Servicer and the Special Servicer may enter into Sub-Servicing
Agreements to provide for the performance by third parties of any or all of its respective obligations hereunder; provided
that the Sub-Servicing Agreement as amended or modified: (i) is consistent with this Agreement in all material respects and
requires the Sub-Servicer to comply with all of the applicable conditions of this Agreement; (ii) provides that if the Master
Servicer or the Special Servicer, as applicable, shall for any reason no longer act in such capacity hereunder (including, without
limitation, by reason of a Servicer Termination Event), the Trustee or its designee shall thereupon assume all of the rights and,
except to the extent they arose prior to the date of assumption, obligations of such party under such agreement, or, alternatively,
may act in accordance with Section 7.02 hereof under the circumstances described therein (subject to Section 3.20(g)
hereof); (iii) provides that the Trustee (for the benefit of the Certificateholders and the related Companion Holder (if applicable)
and the Trustee (as holder of the Lower-Tier Regular Interests) shall be a third party beneficiary under such Sub-Servicing Agreement,
but that (except to the extent the Trustee or its designee assumes the obligations of such party thereunder as contemplated by
the immediately preceding clause (ii)) none of the Trust, the Trustee, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable, any successor master servicer
or special servicer or any Certificateholder (or the related Companion Holder, if applicable) shall have any duties under such
Sub-Servicing Agreement or any liabilities arising therefrom; (iv) permits any purchaser of a Mortgage Loan or Trust Subordinate
Companion Loan pursuant to this Agreement to terminate such Sub-Servicing Agreement with respect to such purchased Mortgage Loan
or Trust Subordinate Companion Loan at its option and without penalty; provided, however, that the Initial Sub-Servicing
Agreements may only be terminated by the Trustee or its designees as contemplated by Section 3.20(g) hereof and in
such additional manner and by such other Persons as is provided in such Sub-Servicing Agreement; (v) does not permit the Sub-Servicer
any direct rights of indemnification that may be satisfied out of assets of the Trust; (vi) does not permit the Sub-Servicer
to modify any Mortgage Loan or Trust Subordinate Companion Loan unless and to the extent the Master Servicer or the Special Servicer,
as applicable, is permitted hereunder to modify such Mortgage Loan or Trust Subordinate Companion Loan; (vii) does not permit
the Sub-Servicer to take any action constituting a Major Decision without the consent of the Master


 






     -321-


     


    

 


Servicer
or the Special Servicer, as applicable (which consent shall not be granted except in accordance with Section 6.08);
(viii) with respect to any Sub-Servicing Agreement entered into after the Closing Date, if such Sub-Servicer is a Servicing
Function Participant or an Additional Servicer, such Sub-Servicer, at the time the related Sub-Servicing Agreement is entered
into, is not a Prohibited Party; and (ix) provides that the Sub-Servicer shall be in default under the related Sub-Servicing
Agreement and such Sub-Servicing Agreement shall be terminated (following the expiration of any applicable Grace Period) if the
Sub-Servicer fails (A) to deliver by the due date any Exchange Act reporting items required to be delivered to the Master
Servicer, Certificate Administrator or Depositor under Article XI or under the Sub-Servicing Agreement or to the master
servicer under any other pooling and servicing agreement that the Depositor is a party to, or (B) to perform in any material
respect any of its covenants or obligations contained in the Sub-Servicing Agreement regarding creating, obtaining or delivering
any Exchange Act reporting items required for any party to this Agreement to perform its obligations under Article XI
or under the Exchange Act reporting items required under any other pooling and servicing agreement that the Depositor is a
party to. Any successor master servicer or special servicer, as applicable, hereunder shall, upon becoming successor master servicer
or special servicer, as applicable, be assigned and may assume any Sub-Servicing Agreements from the predecessor Master Servicer
or the Special Servicer, as applicable (subject to Section 3.20(g) hereof). In addition, each Sub-Servicing Agreement
entered into by the Master Servicer may but need not provide that the obligations of the Sub-Servicer thereunder may terminate
with respect to any Mortgage Loan or Trust Subordinate Companion Loan serviced thereunder at the time such Mortgage Loan or Trust
Subordinate Companion Loan becomes a Specially Serviced Loan; provided, however, that the Sub-Servicing Agreement
may provide (if the Sub-Servicing Agreement provides for Advances by the Sub-Servicer, although it need not so provide) that the
Sub-Servicer will continue to make all Advances and calculations and prepare all reports required under the Sub-Servicing Agreement
with respect to Specially Serviced Loans and continue to collect its Primary Servicing Fees as if no Servicing Transfer Event
had occurred and with respect to REO Properties (and the related REO Loans) as if no REO Acquisition had occurred and to render
such incidental services with respect to such Specially Serviced Loans and REO Properties as are specifically provided for in
such Sub-Servicing Agreement. The Master Servicer or the Special Servicer, as applicable, shall deliver to the Trustee (i) copies
of all Sub-Servicing Agreements entered into by it, in each case, promptly upon its execution and delivery of such documents and
(ii) upon request of the Trustee, any amendments or modifications to such Sub-Servicing Agreements. References in this Agreement
to actions taken or to be taken by the Master Servicer include actions taken or to be taken by a Sub-Servicer on behalf of the
Master Servicer; and, in connection therewith, all amounts advanced by any Sub-Servicer (if the Sub-Servicing Agreement provides
for Advances by the Sub-Servicer, although it need not so provide) to satisfy the obligations of the Master Servicer hereunder
to make Advances shall be deemed to have been advanced by the Master Servicer out of its own funds and, accordingly, in such event,
such Advances shall be recoverable by such Sub-Servicer in the same manner and out of the same funds as if such Sub-Servicer were
the Master Servicer, and, for so long as they are outstanding, such Advances shall accrue interest in accordance with Section 3.03(d),
such interest to be allocable between the Master Servicer and such Sub-Servicer as may be provided (if at all) pursuant to the
terms of the Sub-Servicing Agreement. For purposes of this Agreement, the Master Servicer shall be deemed to have received any
payment when a Sub-Servicer retained by it receives such payment. The Master Servicer or the Special


 






     -322-


     


    

 


Servicer, as applicable,
shall notify the Master Servicer or the Special Servicer, as applicable, the Trustee and the Depositor (and the Special Servicer
shall notify the Operating Advisor) in writing promptly of the appointment by it of any Sub-Servicer, except that the Master Servicer
need not provide such notice as to the Initial Sub-Servicing Agreements.


 


(b)         Each Sub-Servicer shall be authorized to transact business in the state or states in which the related Mortgaged Properties
it is to service are situated, if and to the extent required by applicable law to the extent necessary to ensure the enforceability
of the related Mortgage Loans or Trust Subordinate Companion Loans or the compliance with its obligations under the Sub-Servicing
Agreement and the Master Servicer’s or the Special Servicer’s obligations, as applicable, under this Agreement.


 


(c)         As part of its servicing activities hereunder, the Master Servicer or the Special Servicer, as applicable, for the benefit
of the Trustee and the Certificateholders, shall (at no expense to the Trustee, the Certificateholders or the Trust) monitor the
performance and enforce the obligations of each Sub-Servicer under the related Sub-Servicing Agreement, except that the Master
Servicer shall be required only to use reasonable efforts to cause any Initial Sub-Servicer to comply with the requirements of
Article XI hereof. Such enforcement, including, without limitation, the legal prosecution of claims, termination of
Sub-Servicing Agreements in accordance with their respective terms and the pursuit of other appropriate remedies, shall be in such
form and carried out to such an extent and at such time as is in accordance with the Servicing Standard. The Master Servicer or
the Special Servicer, as applicable, shall have the right to remove a Sub-Servicer retained by it in accordance with the terms
of the related Sub-Servicing Agreement.


 


(d)         In the event the Trustee or its designee becomes successor master servicer and assumes the rights and obligations of the
Master Servicer under any Sub-Servicing Agreement, the Master Servicer, at its expense, shall deliver to the assuming party all
documents and records relating to such Sub-Servicing Agreement and the Mortgage Loans and, if applicable, the Companion Loans then
being serviced thereunder and an accounting of amounts collected and held on behalf of it thereunder, and otherwise use reasonable
efforts to effect the orderly and efficient transfer of the Sub-Servicing Agreement to the assuming party.


 


(e)         Notwithstanding the provisions of any Sub-Servicing Agreement and this Section 3.20, except to the extent provided
in Article XI with respect to the obligations of any Sub-Servicer that is an Initial Sub-Servicer, the Master Servicer
or the Special Servicer, as applicable, shall remain obligated and responsible to the Trustee, the Master Servicer, the Special
Servicer, holders of the Companion Loans serviced hereunder and the Certificateholders for the performance of its obligations and
duties under this Agreement in accordance with the provisions hereof to the same extent and under the same terms and conditions
as if it alone were servicing and administering the Mortgage Loans or Trust Subordinate Companion Loans for which it is responsible,
and the Master Servicer or the Special Servicer, as applicable, shall pay the fees of any Sub-Servicer thereunder as and when due
from its own funds. In no event shall the Trust bear any termination fee required to be paid to any Sub-Servicer as a result of
such Sub-Servicer’s termination under any Sub-Servicing Agreement.


 






     -323-


     


    

 


(f)          The Trustee, upon the request of the Master Servicer or the Special Servicer, as applicable, shall furnish to any Sub-Servicer
any documents necessary or appropriate to enable such Sub-Servicer to carry out its servicing and administrative duties under any
Sub-Servicing Agreement.


 


(g)         Each Sub-Servicing Agreement shall provide that, in the event the Trustee or any other Person becomes successor master servicer,
the Trustee or such successor master servicer shall have the right to terminate such Sub-Servicing Agreement with or without cause
and without a fee. Notwithstanding the foregoing or any other contrary provision in this Agreement, the Trustee and any successor
master servicer shall assume each Initial Sub-Servicing Agreement and (i) the Initial Sub-Servicer’s rights and obligations
under the Initial Sub-Servicing Agreement shall expressly survive a termination of the Master Servicer’s servicing rights
under this Agreement; provided that the Initial Sub-Servicing Agreement has not been terminated in accordance with its provisions;
(ii) any successor master servicer, including, without limitation, the Trustee (if it assumes the servicing obligations of
the Master Servicer) shall be deemed to automatically assume and agree to the then-current Initial Sub-Servicing Agreement without
further action upon becoming the successor master servicer and (iii) this Agreement may not be modified in any manner which
would increase the obligations or limit the rights of the Initial Sub-Servicer hereunder and/or under the Initial Sub-Servicing
Agreement, without the prior written consent of the Initial Sub-Servicer (which consent shall not be unreasonably withheld).


 


(h)         With respect to Mortgage Loans or Trust Subordinate Companion Loans subject to a Sub-Servicing Agreement with the Master
Servicer, the Special Servicer shall, upon request (such request to be made reasonably in advance as appropriate to the circumstances
surrounding such request) of the related Sub-Servicer, reasonably cooperate in delivering reports and information, including remittance
information, and affording access to information to the related Sub-Servicer that would be required to be delivered or afforded,
as the case may be, to the Master Servicer pursuant to the terms hereof.


 


(i)          Notwithstanding any other provision of this Agreement, the Special Servicer shall not enter into any Sub-Servicing Agreement
that provides for the performance by third parties of any or all of its obligations herein, without, prior to the occurrence and
continuance of any Control Termination Event and other than with respect to any Mortgage Loan or Trust Subordinate Companion Loan
that is an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the
Holder of the majority of the Controlling Class, the consent of the Directing Holder, except to the extent necessary for the Special
Servicer to comply with applicable regulatory requirements.


 


Notwithstanding anything to the
contrary herein, no Sub-Servicer shall be permitted under any Sub-Servicing Agreement to make material servicing decisions, such
as loan modifications or determinations as to the manner or timing of enforcing remedies under the Mortgage Loan documents, as
applicable, without the consent of the Master Servicer or the Special Servicer, as applicable.

Interest Reserve Account.


 


(a)  On the P&I
Advance Date occurring in January (except during a leap year) and February of each calendar year commencing in 2018 (in each case,

(b)         On each P&I Advance Date occurring in March (or February, if the related Distribution Date is the final Distribution
Date), the Certificate Administrator shall withdraw, from the Interest Reserve Account an amount equal to the Withheld Amounts
from the preceding January (if applicable) and February, if any, and deposit such amount into the Lower-Tier REMIC Distribution
Account or a Trust Subordinate Companion Loan REMIC Distribution Account, as applicable.

available to verbally answer questions from (a) the Directing Holder ((i) prior to the occurrence and continuance of a Consultation
Termination Event and (ii) other than with respect to any Excluded Loan as to such party) and (b) the Operating Advisor (with
respect to the Special Servicer only), regarding the performance and servicing of the Mortgage Loans, the Trust Subordinate Companion
Loans and/or REO Properties for which the Master Servicer or the Special Servicer, as the case may be, is responsible.


 


Section 3.23       
Controlling Class Certificateholders, Directing Certificateholder and the Risk Retention Consultation Party; Certain
Rights and Powers of Directing Holder and the Risk Retention Consultation Party. (a)  Each Controlling Class Certificateholder
is hereby deemed to have agreed by virtue of its purchase of a Certificate to provide its name and address to the Certificate Administrator
and to notify the Master Servicer, the Certificate Administrator, the Special Servicer and the Operating Advisor of the transfer
of any Certificate of a Controlling Class by delivering a notice to each such Person substantially in the form of Exhibit NN
attached hereto, the selection of a Directing Certificateholder or the resignation or removal thereof. The Directing Certificateholder
is hereby deemed to have agreed by virtue of its purchase of a Certificate to notify the Master Servicer, the Special Servicer,
the Certificate Administrator, the Trustee and the Operating Advisor when such Certificateholder is appointed Directing Certificateholder
and when it is removed or resigns. To the extent there is only one Controlling Class Certificateholder and it is also the
Special Servicer, it shall be the Directing Certificateholder.


 


On the Closing Date, the initial
Directing Certificateholder shall deliver to the parties to this Agreement a certification substantially in the form of Exhibit
P-1G to this


 






     -325-


     


    

 


Agreement.
Upon the resignation or removal of the existing Directing Certificateholder, any successor directing certificateholder shall execute

consultation party shall execute and also deliver to the parties to this Agreement a certification substantially in the form of
Exhibit P-1H to this Agreement prior to being recognized as the new Risk Retention Consultation Party.


 


(b)         Once a Directing Certificateholder has been selected, each of the Master Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator, the Operating Advisor and each other Certificateholder (or Certificate Owner, if applicable)
shall be entitled to rely on such selection unless the Controlling Class Certificateholders entitled to appoint the Directing
Certificateholder, by Certificate Balance, or such Directing Certificateholder shall have notified the Master Servicer, the Special
Servicer, the Trustee, the Certificate Administrator, the Operating Advisor and each other Controlling Class Certificateholder,
in writing, of the resignation of such Directing Certificateholder or the selection of a new Directing Certificateholder. Upon
the resignation of a Directing Certificateholder, the Certificate Administrator shall request the Controlling Class Certificateholders
to select a new Directing Certificateholder. In the event that (i) the Master Servicer, the Certificate Administrator, the
Special Servicer, the Trustee or the Operating Advisor receives written notice from a majority of the Controlling Class Certificateholders
that a Directing Certificateholder is no longer designated and (ii) the Controlling Class Certificateholder that owns
the largest aggregate Certificate Balance of the Controlling Class (or a representative thereof) becomes the Directing Certificateholder
pursuant to the proviso of the definition of “Directing Certificateholder”, then the Controlling Class Certificateholder
that owns the largest aggregate Certificate Balance of the Controlling Class (or its representative) shall provide its name and
address to the Certificate Administrator and notify the Master Servicer, the Certificate Administrator, the Special Servicer, the
Trustee and the Operating Advisor that it is the new Directing Certificateholder; provided that the Master Servicer, the
Certificate Administrator, the Special Servicer, the Trustee and the Operating Advisor shall be entitled to rely on the written
notification provided by the purported Controlling Class Certificateholder that owns the largest aggregate Certificate Balance
of the Controlling Class without independently verifying that such Controlling Class Certificateholder actually owns the largest
aggregate Certificate Balance of the Controlling Class. Additionally, once a Risk Retention Consultation Party has been selected,
each of the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor
and each other Certificateholder (or Certificate Owner, if applicable) shall be entitled to rely on such selection unless the Holders
of the VRR Interest entitled to appoint the Risk Retention Consultation Party, by Certificate Balance, or such Risk Retention Consultation
Party shall have notified the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Operating
Advisor and each other Holder of the VRR Interest, in writing, of the selection of a new Risk Retention Consultation Party.

(c)         Until it receives notice to the contrary, each of the Master Servicer, the Special Servicer, the Certificate Administrator,
the Operating Advisor and the Trustee shall be entitled to rely on the most recent notification with respect to the identity of
the Controlling Class Certificateholder, the Directing Certificateholder and the Risk Retention Consultation Party.


 


(d)         In the event that no Directing Holder has been appointed or identified to the Master Servicer or the Special Servicer, as
applicable, and the Master Servicer or the Special Servicer, as the case may be, has attempted to obtain such information from
the Certificate Administrator and no such entity has been identified to the Master Servicer or the Special Servicer, as applicable,
then until such time as the new Directing Holder is identified, the Master Servicer or the Special Servicer, as applicable, shall
have no duty to consult with, provide notice to, or seek the approval or consent of any such Directing Holder as the case may be.


 


(e)         Upon request, the Certificate Administrator shall deliver to the Depositor, Trustee, the Special Servicer, the Operating
Advisor, the Master Servicer and, prior to the occurrence and continuance of a Consultation Termination Event, the Directing Certificateholder,

Directing Certificateholder or Risk Retention Consultation Party or the existence of a new Controlling Class Certificateholder,
the Certificate Administrator shall notify the Trustee, the Operating Advisor, the Master Servicer and the Special Servicer. Notwithstanding
the foregoing, (a) Eightfold Real Estate Capital, L.P. shall be the initial Directing Certificateholder and shall remain so until
a successor is appointed pursuant to the terms of this Agreement or until a Consultation Termination Event occurs and is continuing,
and (b) NREC shall be the initial Risk Retention Consultation Party and shall remain so until a successor is appointed pursuant
to the terms of this Agreement or until a Consultation Termination Event occurs and is continuing.


 


Until it receives notice to the
contrary, each of the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee
shall be entitled to rely on the preceding sentence with respect to the identity of the Directing Certificateholder and the Risk
Retention Consultation Party.


 


(f)          If to the extent the Certificate Administrator determines that a Class of Book-Entry Certificates is the Controlling Class,
the Certificate Administrator shall notify the related Certificateholders of such Class (through the Depository) of the Class becoming
the Controlling Class.


 


(g)         Each Certificateholder acknowledges and agrees, by its acceptance of its Certificates, that: (i) the Directing Holder
may have special relationships and interests that conflict with those of Holders of one or more Classes of Certificates; (ii) the
Directing Holder may act solely in the interests of the Holders of the Controlling Class; (iii) the Directing Certificateholder
does not have any liability or duties to the Holders of any Class of Certificates other than the Controlling Class; (iv) the
Directing Holder may take actions that favor interests of the Holders of one or more Classes of Certificates, including, without

and
(v) the Directing Holder shall have no liability whatsoever (other than to a Controlling Class Certificateholder, to
the extent the Directing Certificateholder is the Directing Holder) for having so acted, and no Certificateholder may take any
action whatsoever against the Directing Holder or any director, officer, employee, agent or principal of the Directing Holder
for having so acted.


 


Each Certificateholder acknowledges

Party may act solely in the interests of the Holders of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline

of any Class of Certificates other than the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest,
as applicable; (iv) the Risk Retention Consultation Party may take actions that favor interests of the Holders of one or more
Classes including the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable, over
the interests of the Holders of one or more other Classes of Certificates; and (v) the Risk Retention Consultation Party shall
have no liability whatsoever (other than to a Holder of an VRR Interest, the Y&L Towers VRR Interest or the Standard Highline
VRR Interest, as applicable) for having so acted as set forth in clauses (i) through (iv) above, and no Certificateholder
may take any action whatsoever against the Risk Retention Consultation Party or any director, officer, employee, agent or principal
of the Risk Retention Consultation Party for having so acted.


 


(h)         All requirements of the Master Servicer and the Special Servicer to provide notices, reports, statements or other information
(including the access to information on a website) to the Directing Holder contained in this Agreement shall also apply to each
Companion Holder with respect to information relating to the related Serviced Whole Loan, as applicable; provided, however,
that neither the Master Servicer nor the Special Servicer shall provide information that comprises Privileged Information following
the date upon which they receive notice that such Standard Highline Non-Trust Junior Subordinate Companion Loan, Standard Highline
Non-Trust Senior Subordinate Companion Loan or Standard Highline Trust Subordinate Companion Loan is subject to a Standard Highline
Non-Trust Junior Subordinate Companion Loan Control Termination Event, a Standard Highline Non-Trust Senior Companion Loan Control
Termination Event or a Standard Highline Trust Subordinate Companion Loan Control Termination Event, as applicable, and thereafter
the Master Servicer and the Special Servicer shall only be required to provide the Standard Highline Directing Holder with such
information as is expressly required to be delivered pursuant to the Intercreditor Agreement; provided, however,
that nothing in this subsection (h) shall in any way eliminate the obligation to deliver any information required to be
delivered under the related Intercreditor Agreement.


 


(i)          Until it receives notice to the contrary, each of the Master Servicer, the Special Servicer, the Certificate Administrator,
the Trustee and the Operating Advisor shall be entitled to rely on the most recent notification with respect to the identity and
contact information of the Controlling Class Certificateholder, the Directing Holder, the Risk Retention Consultation Party
and any AB Whole Loan Controlling Holder.


 






     -328-


     


    

 


(j)          With respect to a Serviced Whole Loan and any approval and consent rights in this Agreement with respect to such Serviced
Whole Loan, the Directing Holder shall exercise such rights in accordance with the related Intercreditor Agreement.


 


(k)         The Certificate Registrar shall determine which Class of Certificates is the then-current Controlling Class or provide the
name, contact information and address of the then-current Directing Certificateholder within two (2) Business Days of a request
from the Master Servicer, the Special Servicer, Certificate Administrator, Trustee, Operating Advisor or any Certificateholder
and provide such information to the requesting party.


 


(l)          At any time that the Controlling Class Certificateholder is the holder of a majority of the Class F Certificates
and the Class F Certificates are the Controlling Class, it may waive its right (a) to appoint the Directing Certificateholder
and (b) to exercise any of the Directing Certificateholder’s rights under this Agreement by irrevocable written notice delivered
to the Depositor, the Certificate Administrator (which shall be via email to trustadministrationgroup@wellsfargo.com), the Trustee,
the Master Servicer, the Special Servicer and the Operating Advisor. Notwithstanding anything to the contrary contained herein,
during such time as a Control Termination Event or Consultation Termination Event is in existence solely as a result of the operation
of clause (ii) of the definition of Control Termination Event and clause (ii) of the definition of Consultation
Termination Event, such Control Termination Event or Consultation Termination Event shall be deemed to no longer be in existence
and have not occurred with respect to any unaffiliated third party to whom the Controlling Class Certificateholder that irrevocably
waived its right to exercise any of the rights of the Controlling Class Certificateholder has sold or transferred all or a
portion of its interest in the Class F Certificates if such unaffiliated third party holds the majority of the Controlling
Class after giving effect to such transfer (the “Non-Waiving Successor”). Following any such sale or transfer,
the Non-Waiving Successor shall again have the rights of the Controlling Class Certificateholder as set forth herein (including
the rights to appoint a Directing Certificateholder or cause the exercise of the rights of the Directing Certificateholder) without
regard to any prior waiver by the predecessor Controlling Class Certificateholder. The Non-Waiving Successor shall also have
the right to exercise any of the rights of the Controlling Class Certificateholder. No Non-Waiving Successor described above
shall have any consent rights with respect to any Mortgage Loan or Trust Subordinate Companion Loan that became a Specially Serviced
Loan prior to the sale or transfer of the Class F Certificates to the Non-Waiving Successor and had not also become a Corrected
Loan prior to such sale or transfer until such time as such Mortgage Loan or Trust Subordinate Companion Loan becomes a Corrected
Loan.


 


(m)        Promptly upon its determination of a change in the Controlling Class, the Certificate Administrator shall (i) include
on its statement made available pursuant to Section 4.02(a) of this Agreement the identity of the new Controlling Class
and (ii) provide to the Master Servicer, the Special Servicer and the Operating Advisor notice of such event and the identity
and contact information of the new Controlling Class Certificateholder (the cost of obtaining such information from DTC being
an expense of the Trust). The Certificate Administrator shall notify the Operating Advisor, the Master Servicer and the Special
Servicer within ten (10) Business Days of the existence or cessation of (i) any Control Termination Event, (ii) any Consultation
Termination Event or (iii) any Operating Advisor Consultation Event.


 






     -329-


     


    

 


Upon
the Certificate Administrator’s determination that a Control Termination Event, a Consultation Termination Event or an Operating
Advisor Consultation Event has occurred or is terminated, the Certificate Administrator shall, within ten (10) Business Days,
post a “special notice” on the Certificate Administrator’s Website pursuant to this provision.


 


In the event that a Control Termination
Event has occurred due to a reduction of the Certificate Balance of the Class F Certificates (taking into account the application
of any Cumulative Appraisal Reduction Amounts to notionally reduce the Certificate Balance of such Class in accordance with Section
4.05(a) hereof) to less than 25% of the Original Certificate Balance thereof, such special notice shall state “A Control
Termination Event has occurred due to the reduction of the Certificate Balance of the Class F Certificates to less than 25%
of the Original Certificate Balance thereof.”


 


In the event that a Control Termination
Event or Consultation Termination Event has occurred due to the irrevocable waiver by a Class F Certificateholder who has
become the Controlling Class Certificateholder of its right to appoint a Directing Certificateholder or to exercise any of
the rights of the Controlling Class Certificateholder, such special notice shall state “A Control Termination Event
and a Consultation Termination Event has occurred due to the irrevocable waiver by the Controlling Class Certificateholder
of its rights as Controlling Class Certificateholder.”


 


In the event that a Consultation
Termination Event has occurred due to the reduction of each Class of Control Eligible Corresponding Certificates below 25% of its
Original Certificate Balance, in each case without regard to the application of any Cumulative Appraisal Reduction Amounts, such
special notice shall state: “A Consultation Termination Event has occurred because no Class of Control Eligible Corresponding
Certificates exists where such Class’s aggregate Certificate Balance is at least equal to 25% of the Original Certificate
Balance of that Class, in each case without regard to the application of any Cumulative Appraisal Reduction Amounts.”


 


In the event of any transfer
of a Class F Certificate, and upon notice to the Certificate Administrator in the form of Exhibit NN that results
in a termination of a Control Termination Event or a Consultation Termination Event, such “special notice” shall state:
“A Consultation Termination Event or a Control Termination Event has been terminated and is no longer in effect due to a
transfer of a majority interest of the Controlling Class Certificates to an unaffiliated third party which has terminated
any waiver by the prior Holder.”


 


The Directing Holder shall not
have any consent or consultation rights with respect to any Mortgage Loan determined to be an Excluded Loan as to either the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class. Likewise,
the Risk Retention Consultation Party shall not have any consultation rights with respect to any Mortgage Loan or Trust Subordinate
Companion Loan, as applicable, determined to be an Excluded Loan as to either such Risk Retention Consultation Party or the Holder
of the majority of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable. In either
such case, in respect of the servicing of any such Excluded Loan, a Control Termination Event and Consultation Termination Event
will be deemed to have occurred with respect to such Excluded Loan.

Section 3.24       
Intercreditor Agreements. (a)  Each of the Master Servicer and the Special Servicer acknowledges and agrees
that each Serviced Whole Loan being serviced under this Agreement and each Mortgage Loan with mezzanine debt is subject to the
terms and provisions of the related Intercreditor Agreement and each agrees to service each such Serviced Whole Loan and each Mortgage
Loan with mezzanine debt in accordance with the related Intercreditor Agreement and this Agreement, including, without limitation,
effecting distributions and allocating reimbursement of expenses in accordance with the related Intercreditor Agreement and, in
the event of any conflict between the provisions of this Agreement and the related Intercreditor Agreement, the related Intercreditor
Agreement shall govern. Notwithstanding anything contrary in this Agreement, each of the Master Servicer and Special Servicer agrees
not to take any action with respect to a Serviced Whole Loan or a Mortgage Loan with mezzanine debt or the related Mortgaged Property
without the prior consent of the related Companion Holder or mezzanine lender, as applicable, to the extent that the related Intercreditor
Agreement provides that such Companion Holder or mezzanine lender, as applicable, is required or permitted to consent to such action.
Each of the Master Servicer and Special Servicer acknowledges and agrees that each Companion Holder and each mezzanine lender or
its respective designee has the right to purchase the related Mortgage Loan pursuant to the terms and conditions of this Agreement
and the related Intercreditor Agreement to the extent provided for therein. All parties hereto further acknowledge and agree that
any AB Whole Loan Controlling Holder will have the right to replace the Special Servicer solely with respect to the related Pooled
Serviced AB Whole Loan and shall be entitled to exercise all approval rights of the Directing Holder regarding any Asset Status
Report in respect of the related Mortgage Loan or related REO Property, without regard to the occurrence of any Control Termination
Event or Consultation Termination Event with respect to the related Pooled Serviced AB Whole Loan, to the extent provided for herein
and in the related Intercreditor Agreement.


 


(b)         Neither the Master Servicer nor the Special Servicer shall have any liability for any cost, claim or damage that arises
from any entitlement in favor of a Companion Holder or a mezzanine lender under the related Intercreditor Agreement or conflict
between the terms of this Agreement and the terms of such Intercreditor Agreement. Notwithstanding any provision of any Intercreditor
Agreement that may otherwise require the Master Servicer or the Special Servicer to abide by any instruction or direction of a
Companion Holder or a mezzanine lender, neither the Master Servicer nor the Special Servicer shall be required to comply with any
instruction or direction the compliance with which requires an Advance that constitutes or would constitute a Nonrecoverable Advance.
In no event shall any expense arising from compliance with an Intercreditor Agreement constitute an expense to be borne by the
Master Servicer or the Special Servicer for its own account without reimbursement. In no event shall the Master Servicer or the
Special Servicer be required to consult with or obtain the consent of any Companion Holder or a mezzanine lender unless such Companion
Holder or mezzanine lender has delivered notice of its identity and contact information to each of the parties to this Agreement
(upon which notice each of the parties to this Agreement shall be conclusively entitled to rely). As of the Closing Date, the contact
information for the Companion Holders and mezzanine lenders is as set forth in the related Intercreditor Agreement. In no event
shall the Master Servicer or the Special Servicer, as applicable, be required to consult with or obtain the consent of a new Directing
Certificateholder or a new Controlling Class Certificateholder or consult with a new Risk Retention Consultation Party unless
the Certificate Administrator has delivered notice to the Master Servicer or the Special Servicer, as applicable, as required under


 






     -331-


     


    

 


Section 3.23(e)
or the Master Servicer or the Special Servicer, as applicable, have actual knowledge of the identity and contact information
of a new Directing Certificateholder, a new Controlling Class Certificateholder or a new Risk Retention Consultation Party.


 


(c)         No direction or disapproval of the Companion Holders or any mezzanine lender shall (a) require or cause the Master
Servicer or the Special Servicer to violate the terms of a Mortgage Loan or Serviced Companion Loan, applicable law or any provision
of this Agreement, including the Master Servicer’s or the Special Servicer’s obligation to act in accordance with the
Servicing Standard and to maintain the REMIC status of each Trust REMIC and the grantor trust status of the Grantor Trust, (b) result
in the imposition of a “prohibited transaction” or “prohibited contribution” tax under the REMIC Provisions
or (c) materially expand the scope of the Special Servicer’s, Trustee’s, the Certificate Administrator’s
or the Master Servicer’s responsibilities under this Agreement.


 


(d)         With respect to any Serviced Pari Passu Companion Loan, notwithstanding any rights the Operating Advisor, the Directing
Certificateholder or the Risk Retention Consultation Party hereunder may have to consult with respect to any action or other matter
with respect to the servicing of such Companion Loan, to the extent the related Intercreditor Agreement provides that such right
is exercisable by the related Companion Holder or is exercisable in conjunction with any related Companion Holder, the Directing
Certificateholder and the Risk Retention Consultation Party shall not be permitted to exercise such right or, to the extent provided
in the related Intercreditor Agreement, shall be required to exercise such right in conjunction with the related Companion Holder,
as applicable (except to the extent that the Directing Certificateholder or the Risk Retention Consultation Party is the related
Serviced Whole Loan Controlling Holder). Additionally, notwithstanding anything in this Agreement to the contrary, the Master Servicer
or the Special Servicer, as the case may be, shall consult, seek the approval or obtain the consent of the holder of any Serviced
Companion Loan with respect to any matters with respect to the servicing of such Companion Loan to the extent required under related
Intercreditor Agreement and shall not take such actions requiring consent of the related Companion Holder without such consent.
In addition, notwithstanding anything to the contrary, the Master Servicer or the Special Servicer, as the case may be, shall deliver
reports and notices to the related Companion Holder as required under the Intercreditor Agreement.


 


(e)         Notwithstanding anything in this Agreement to the contrary, the Special Servicer shall be required (1) to provide copies
of any notice, information and report that it is required to provide to the Controlling Class Certificateholder pursuant to
this Agreement with respect to any Major Decisions or the implementation of any recommended actions outlined in an Asset Status
Report relating to a Serviced Whole Loan, to the related Companion Holder, within the same time frame it is required to provide
to the Controlling Class Certificateholder (for this purpose, without regard to whether such items are actually required to
be provided to the Controlling Class Certificateholder under this Agreement due to the occurrence and continuance of a Control
Termination Event or a Consultation Termination Event) and (2) to consult with any related Companion Holder on a strictly non-binding
basis, to the extent having received such notices, information and reports, such related Companion Holder requests consultation
with respect to any such Major Decisions or the implementation of any recommended actions outlined in an Asset Status Report relating
to a Serviced Whole Loan, and consider alternative actions


  



     -332-


     


    

 





recommended
by such related Companion Holder; provided that after the expiration of a period of ten (10) Business Days from the delivery
to such related Companion Holder by the Special Servicer of written notice of a proposed action, together with copies of the notice,
information and report required to be provided to the Controlling Class Certificateholder, the Special Servicer shall no
longer be obligated to consult with such related Companion Holder, whether or not such related Companion Holder has responded
within such ten (10) Business Day period (unless, the Special Servicer proposes a new course of action that is materially different
from the action previously proposed, in which case such ten (10) Business Day period shall be deemed to begin anew from the date
of such proposal and delivery of all information relating thereto). Notwithstanding the consultation rights of the related Companion
Holder, the Master Servicer or Special Servicer, as applicable, may make any Major Decision or take any action set forth in the
Asset Status Report before the expiration of the aforementioned ten (10) Business Day period if the Master Servicer or Special
Servicer, as applicable, determines that immediate action with respect thereto is necessary to protect the interests of the Certificateholders
and the related Companion Holder. In no event shall the Master Servicer or the Special Servicer, as applicable, be obligated at
any time to follow or take any alternative actions recommended by the related Companion Holder.


 


(f)          In addition to the consultation rights of the holder of a Serviced Pari Passu Companion Loan provided in the immediately
preceding paragraph, such Companion Holder shall have the right to attend (in person or telephonically, in the discretion of the
Master Servicer or Special Servicer, as the case may be) annual meetings with the Master Servicer or the Special Servicer at the
offices of the Master Servicer or the Special Servicer, as applicable, upon reasonable notice and at times reasonably acceptable
to the Master Servicer or the Special Servicer, as applicable, in which servicing issues related to the related Whole Loan are
discussed.


 


(g)         With respect to any Serviced Whole Loan, the Special Servicer shall not modify, waive or amend the terms of the related
Intercreditor Agreement such that the monthly remittance to the holder of the related Companion Loan is required earlier than 2
Business Days after receipt by the Master Servicer of the related Periodic Payment without the consent of the Master Servicer.


 


(h)         Any modification or amendment to an Intercreditor Agreement that would materially adversely affect the Master Servicer or
the Special Servicer, as applicable, shall require the prior consent of the Master Servicer or the Special Servicer, as applicable.


 


(i)          With respect to each Serviced Whole Loan, if any Serviced Companion Loan becomes the subject of an “asset review”
(or such analogous term defined in the related Other Pooling and Servicing Agreement) pursuant to the related Other Pooling and
Servicing Agreement, the Master Servicer, the Special Servicer, the Trustee and the Custodian shall reasonably cooperate with the
asset representations reviewer under the Other Pooling and Servicing Agreement or any other party to the Other Pooling and Servicing
Agreement in connection with such Asset Review by providing the asset representations reviewer under the Other Pooling and Servicing
Agreement or such other requesting party with any documents reasonably requested by the asset representations reviewer under the
Other Pooling and Servicing Agreement or such other requesting party, but only to the extent such documents are in


 






     -333-


     


    

 


the
possession of the Master Servicer, the Special Servicer, the Trustee or the Custodian, as the case may be.


 


Section 3.25       
Rating Agency Confirmation. (a)  Notwithstanding the terms of any related Mortgage Loan documents or other
provisions of this Agreement, if any action under any Mortgage Loan documents or this Agreement requires Rating Agency Confirmation
as a condition precedent to such action, if the party (the “RAC Requesting Party”) required to obtain such Rating
Agency Confirmation from each Rating Agency has made a request to any Rating Agency for such Rating Agency Confirmation and, within
ten (10) Business Days of the Rating Agency Confirmation request being posted to the 17g-5 Information Provider’s Website,
such Rating Agency has not replied to such request or has responded in a manner that indicates that such Rating Agency is neither
reviewing such request nor waiving the requirement for Rating Agency Confirmation, then such RAC Requesting Party shall be required
to confirm (through direct communication and not by posting any confirmation on the 17g-5 Information Provider’s Website)
that the applicable Rating Agency has received the Rating Agency Confirmation request, and, if it has not, promptly request the
related Rating Agency Confirmation again (which may also be through direct communication). The circumstances described in the preceding
sentence are referred to in this Agreement as a “RAC No-Response Scenario.” Once the RAC Requesting Party has
sent a request for a Rating Agency Confirmation to the 17g-5 Information Provider, such RAC Requesting Party, may, but shall not
be obligated to send such request directly to the Rating Agencies in accordance with the procedures set forth in this Section 3.25.


 


If there is no response to such
Rating Agency Confirmation request within five (5) Business Days of such second request in a RAC No-Response Scenario or if such
Rating Agency has responded in a manner that indicates such Rating Agency is neither reviewing such request nor waiving the requirement
for Rating Agency Confirmation, then (x) with respect to any condition in any Mortgage Loan document requiring such Rating
Agency Confirmation or with respect to any other matter under this Agreement relating to the servicing of the Mortgage Loans and
the Trust Subordinate Companion Loans (other than as set forth in clause (y) below), the requirement to obtain a Rating
Agency Confirmation shall be deemed not to apply for such matter at such time (as if such requirement did not exist) with respect
to such Rating Agency and the Master Servicer or the Special Servicer, as the case may be, may then take such action if the Master
Servicer or the Special Servicer, as applicable, confirms its original determination (made prior to making such request) that taking
the action with respect to which it requested the Rating Agency Confirmation would still be consistent with the Servicing Standard,
and (y) with respect to a replacement of the Master Servicer or the Special Servicer, such condition shall be deemed not to
apply (as if such requirement did not exist) if (i) the applicable replacement master servicer or special servicer, as applicable,
it has been appointed and currently serves as a master servicer or special servicer is listed on S&P’s Select Servicer
List as a U.S. Commercial Mortgage Master Servicer or U.S. Commercial Mortgage Special Servicer, as applicable, if S&P is the
non-responding Rating Agency, (ii) the applicable replacement master servicer or special servicer is rated at least “CMS3”
(in the case of the replacement master servicer) or “CSS3” (in the case of the replacement special servicer), if Fitch
is the non-responding Rating Agency or (iii) KBRA has not cited servicing concerns with respect to the replacement master servicer
or special servicer as the sole or a material factor in any qualification, downgrade or withdrawal of the ratings (or placement
on “watch status” in contemplation of a ratings downgrade or withdrawal) of securities in any other commercial mortgage-backed
securitization transaction


 






     -334-


     


    

 


serviced
by such replacement master servicer or special servicer prior to the time of determination, if KBRA is the non-responding Rating
Agency. In addition, with respect to the Yorkshire & Lexington Towers Whole Loan and The Standard Highline NYC Whole Loan,
with respect to a replacement of the Master Servicer or the Special Servicer, such condition shall be deemed not to apply (as
if such requirement did not exist) if the replacement master servicer or replacement special servicer is acting as master servicer
or special servicer, as applicable, in a commercial mortgage loan securitization that was rated by a Rating Agency within the
12-month period prior to the date of determination and Morningstar has not qualified, downgraded or withdrawn the then-current
rating or ratings of one or more classes of CMBS certificates citing servicing concerns with the replacement master servicer or
replacement special servicer, as applicable, as the sole or material factor in such rating action, if Morningstar is the non-responding
Rating Agency.


 


Any Rating Agency Confirmation
request made by the Master Servicer, Special Servicer, Certificate Administrator or Trustee, as applicable, pursuant to this Agreement,
shall be made in writing, which writing shall contain a cover page indicating the nature of the Rating Agency Confirmation request,
and shall contain all back-up material necessary for the Rating Agency to process such request. Such written Rating Agency Confirmation
request shall be provided in electronic format to the 17g-5 Information Provider, and the 17g-5 Information Provider shall post
such request on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).


 


Promptly following the Master
Servicer’s or the Special Servicer’s determination to take any action discussed in this Section 3.25(a)
following any requirement to obtain a Rating Agency Confirmation being deemed not to apply (as if such requirement did not exist),
the Master Servicer or the Special Servicer, as applicable, shall provide electronic written notice to the 17g-5 Information Provider
of the action taken for the particular item at such time, and the 17g-5 Information Provider shall promptly post such notice on
the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).


 


(b)         Notwithstanding anything to the contrary in this Section 3.25, for purposes of the provisions of any Mortgage
Loan document relating to defeasance (including without limitation the type of collateral acceptable for use as defeasance collateral)
or release or substitution of any collateral, any Rating Agency Confirmation requirement in the Mortgage Loan documents for which
the Master Servicer or the Special Servicer would have been permitted to waive obtaining such Rating Agency Confirmation pursuant
to Section 3.25(a) shall be deemed not to apply (as if such requirement did not exist).


 


(c)         For all other matters or actions not specifically discussed in Section 3.25(a) above, the applicable RAC Requesting
Party shall deliver Rating Agency Confirmation from each Rating Agency.


 


Section 3.26       
The Operating Advisor. (a)  The Operating Advisor shall promptly review (i) the actions of the Special
Servicer with respect to a Mortgage Loan or Trust Subordinate Companion Loan when it is a Specially Serviced Loan (as provided
in Section 3.19(d), Section 3.26 and Section 6.08) and after the occurrence and during the
continuance of an Operating Advisor Consultation Event the actions of the Special Servicer with


 






     -335-


     


    

 


respect
to Major Decisions relating to the Mortgage Loans or Trust Subordinate Companion Loans when they are not a Specially Serviced
Loan when a Major Decision Reporting Package has been delivered, (ii) all reports by the Special Servicer made available to Privileged
Persons on the Certificate Administrator’s Website; and (iii) each Asset Status Report (after the occurrence and during
the continuance of an Operating Advisor Consultation Event) and each Final Asset Status Report delivered to the Operating Advisor
by the Special Servicer. The Operating Advisor shall perform its duties hereunder in accordance with the Operating Advisor Standard.
In addition and for the avoidance of doubt, although the Operating Advisor may have certain consultation duties with the Master
Servicer with respect to certain Major Decisions processed by the Master Servicer, the Operating Advisor will have no obligations
or responsibility at any time to review or assess the actions of the Master Servicer for compliance with the Servicing Standard,
and the Operating Advisor will not be required to consider such Master Servicer actions in connection with any Operating Advisor
Annual Report.


 


(b)         The Operating Advisor and its Affiliates will be obligated to keep confidential any information appropriately labeled as
“Privileged Information” received from the Special Servicer or Directing Holder in connection with the Directing Holder’s
exercise of its rights under this Agreement (including, without limitation, in connection with the review and/or approval of any
Asset Status Report) or otherwise in connection with this transaction, except under the circumstances described in Section 3.26(f)
and subject to any Privileged Information Exception or law, rule, regulation, order, judgment or decree requiring the disclosure
of such labeled Privileged Information. Subject to the terms and conditions in this Agreement related to Privileged Information,
the Operating Advisor agrees that it shall use information received from the Special Servicer pursuant to the terms of this Agreement
solely for purposes of complying with its duties and obligations hereunder.


 


(c)         (i)  Based on the Operating Advisor’s review of any assessment of compliance report, any attestation report,
any Major Decision Reporting Package, and/or Asset Status Report (in the case of a Major Decision Reporting Package or Asset Status
Report, after the occurrence and during the continuance of an Operating Advisor Consultation Event), any Final Asset Status Report
and other reports by the Special Servicer made available to Privileged Persons that are posted on the Certificate Administrator’s
Website during the prior calendar year, the Operating Advisor shall (if, at any time during the prior calendar year, (i) any
Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Trust Subordinate Companion Loan was a Specially Serviced Loan or (ii) the
Operating Advisor was entitled to consult with the Special Servicer with respect to any Major Decision during the prior calendar
year) deliver to the Depositor, the Certificate Administrator (who shall promptly post such report on the Certificate Administrator’s
Website in accordance with Section 3.13(b)) and the 17g-5 Information Provider (who shall post it to the 17g-5 Information
Provider’s Website in accordance with Section 3.13(c)) within one hundred twenty (120) days of the end of the
prior calendar year, an annual report (the “Operating Advisor Annual Report”), substantially in the form of
Exhibit V (which form may be modified or altered as to either its organization or content by the Operating Advisor, subject
to compliance of such form with the terms and provisions of this Agreement including, without limitation, provisions herein relating
to Privileged Information; provided, however, that in no event shall the information or any other content included
in the Operating Advisor Annual Report contravene any provision of this Agreement), that (a) sets forth whether the Operating Advisor
believes, in its sole discretion exercised in good faith, that the Special


 






     -336-


     


    

 


Servicer
is operating in compliance with the Servicing Standard with respect to its performance of its duties under this Agreement with
respect to Specially Serviced Loans (and, after the occurrence and during the continuance of an Operating Advisor Consultation
Event, with respect to Major Decisions on non-Specially Serviced Loans) during the prior calendar year on a “asset-level
basis”, and (b) identifies (1) which, if any, standards the Operating Advisor believes, in its sole discretion
exercised in good faith, the Special Servicer has failed to comply and (2) any deviations from the Special Servicer’s
obligations under this Agreement with respect to the resolution or liquidation of any Specially Serviced Loan or REO Property
(other than with respect to any REO Property related to any Non-Serviced Mortgage Loan); provided, however, that
in the event the Special Servicer is replaced, the Operating Advisor Annual Report shall only relate to the Special Servicer that
was acting as Special Servicer as of December 31 in the prior calendar year and is continuing in such capacity through the date
of such Operating Advisor Annual Report. In preparing any Operating Advisor Annual Report, the Operating Advisor shall not be
required to report on instances of non-compliance with, or deviations from, the Servicing Standard or the Special Servicer’s
obligations under this Agreement that the Operating Advisor determines, in its sole discretion exercised in good faith, to be
immaterial. As used in connection with the Operating Advisor Annual Report, the term “asset-level basis” refers to
the Special Servicer’s performance of its duties with respect to the pool of Specially Serviced Loans (and, after the occurrence
and continuance of an Operating Advisor Consultation Event, with respect to Major Decisions on non-Specially Serviced Loans) under
this Agreement taking into account the Special Servicer’s specific duties under this Agreement as well as the extent to
which those duties were performed in accordance with the Servicing Standard, with reasonable consideration by the Operating Advisor
of any Assessment of Compliance Report, Attestation Report, Major Decision Reporting Package, Asset Status Report (after the occurrence
and during the continuance of an Operating Advisor Consultation Event), Final Asset Status Report and other information, in each
case, delivered to the Operating Advisor by the Special Servicer (other than any communications between the Directing Holder and
the Special Servicer that would be Privileged Information) pursuant to this Agreement. Subject to the restrictions in this Agreement,
including, without limitation, Section 3.26(f) hereof, each such Operating Advisor Annual Report shall comply with
all of the confidentiality requirements described in this Agreement regarding Privileged Information (subject to any permitted
exceptions). Such Operating Advisor Annual Report shall be delivered to the Depositor, the Certificate Administrator (which shall
promptly post such Operating Advisor Annual Report on the Certificate Administrator’s Website in accordance with Section 3.13(b))
and the 17g-5 Information Provider (which shall promptly post such Operating Advisor Annual Report on the 17g-5 Information Provider’s
Website in accordance with Section 3.13(c)); provided, however, that the Special Servicer shall be given
an opportunity to review the Operating Advisor Annual Report at least five (5) Business Days prior to its delivery to the Depositor,
the Certificate Administrator and the 17g-5 Information Provider. The Operating Advisor shall have no obligation to adopt any
comments to the Operating Advisor Annual Report that are provided by the Special Servicer.


 


(ii)           In the event the Operating Advisor’s ability to perform its obligations in respect of the Operating Advisor Annual
Report is limited or prohibited due to the failure of a party hereto to timely deliver notice of action and information required
to be delivered to the Operating Advisor or because such information is inaccurate or incomplete, the Operating Advisor shall set
forth such limitations or prohibitions in the related Operating Advisor Annual Report and the Operating Advisor shall not be subject
to any liability


 






     -337-


     


    

 


arising
from such limitations or prohibitions. The Operating Advisor shall be entitled to rely on the accuracy and completeness of any
information it is provided without liability for any such reliance hereunder.


 


(iii)          The ability to perform the duties of the Operating Advisor and the quality and the depth of any Operating Advisor Annual
Report shall be dependent upon the timely receipt of information prepared or made available by others and the accuracy and the
completeness of such information. In addition, in no event will the Operating Advisor have the power to compel any transaction
party to take, or refrain from taking, any action. The Operating Advisor shall be entitled to conclusively rely on the accuracy
and completeness of any information it is provided without liability for any such reliance thereunder.


 


(iv)          In the event a lack of access to Privileged Information limits or prohibits the Operating Advisor from performing its duties
under this Agreement, the Operating Advisor shall set forth any such limitations or prohibitions known to the Operating Advisor
in the related Operating Advisor Annual Report, and the Operating Advisor shall not be subject to any liability arising from such
limitations or prohibitions.


 


(d)         (i)  After the calculation has been finalized (and if an Operating Advisor Consultation Event has occurred and
is continuing prior to the utilization) by the Special Servicer of any of the calculations related to (A) Appraisal Reduction
Amounts, (B) Collateral Deficiency Amounts or (C) net present value in accordance with Section 1.02(iv),
the Special Servicer shall forward such calculations, together with any supporting material or additional information necessary
in support thereof (including such additional information reasonably requested by the Operating Advisor to confirm the mathematical
accuracy of such calculations, but not including any Privileged Communications and, in the case of any Appraisal Reduction Amount
or Collateral Deficiency Amount, only to the extent the Master Servicer has provided such information to the Special Servicer),
to the Operating Advisor promptly, but in any event no later than two (2) Business Days after preparing such calculations, and
the Operating Advisor shall promptly, but no later than three (3) Business Days after receipt of such calculations and any supporting
or additional materials recalculate the accuracy of the mathematical calculations and the corresponding application of the non-discretionary
portion of the applicable formulas required to be utilized in connection with any such calculation.


 


(ii)           In connection with this Section 3.26(d), in the event the Operating Advisor does not agree with the mathematical
calculations of the net present value, Appraisal Reduction Amount or Collateral Deficiency Amount (as calculated by the Special
Servicer) or the application of the applicable non-discretionary portions of the formula required to be utilized for such calculation,
the Operating Advisor and the Special Servicer shall consult with each other in order to resolve any material inaccuracy in the
mathematical calculations or the application of the non-discretionary portions of the related formula in arriving at those mathematical
calculations or any disagreement within five (5) Business Days of delivery of such calculations to the Operating Advisor. The Master
Servicer shall cooperate with the Special Servicer and provide any information reasonably requested by the Special Servicer necessary
for the calculation of the Appraisal Reduction Amount that is in the Master Servicer’s possession or reasonably obtainable
by


 






     -338-


     


    

 


the
Master Servicer. In the event the Operating Advisor and the Special Servicer are not able to resolve such inaccuracies or disagreement
prior to the end of such five (5) Business Day period, the Operating Advisor shall promptly notify the Certificate Administrator
of such disagreement and the Certificate Administrator shall examine the calculations and supporting materials provided by the
Operating Advisor and the Special Servicer and determine which calculation is to apply (and shall provide notice of such determination
to the Operating Advisor and the Special Servicer). In making such determination, the Certificate Administrator may hire an independent
third party to assist with any such calculation at the expense of the Trust. The Certificate Administrator shall be entitled to
conclusively rely on such third party calculation.


 


(e)         Notwithstanding the foregoing, prior to the occurrence and continuance of an Operating Advisor Consultation Event, the Operating
Advisor’s review will be limited to an after-the-action review of the reports and material described above (together with
any additional information and material reviewed by the Operating Advisor) and, it shall have no involvement with respect to collateral
substitutions, assignments, workouts, modifications, consents, waivers, insurance policies, mortgagor substitutions, lease changes
or other similar actions that the Special Servicer may perform under this Agreement and will have no obligations at any time with
respect to any Non-Serviced Mortgage Loan. In addition, with respect to the Operating Advisor’s review of net present value
calculations as described above, the Operating Advisor’s recalculation will not take into account the reasonableness of Special
Servicer’s property and borrower performance assumptions or other similar discretionary portions of the net present value
calculation.


 


(f)          The Operating Advisor and its Affiliates shall keep all information appropriately labeled as “Privileged Information”
confidential and shall not, without the prior written consent of the Special Servicer and (for so long as no Consultation Termination
Event is continuing) the Directing Holder (with respect to any Mortgage Loan or Trust Subordinate Companion Loan other than a Non-Serviced
Whole Loan and any applicable Excluded Loan), disclose such information to any other Person (including any Certificateholders which
are not then included in the Control Eligible Regular Interests, other than the Directing Certificateholder and the Risk Retention
Consultation Party), other than (i) to the extent expressly set forth herein, to the other parties to this Agreement with
a notice indicating that such information is Privileged Information, (ii) pursuant to a Privileged Information Exception or
(iii) where necessary to support specific findings or conclusions concerning allegations of deviations from the Servicing
Standard (A) in the Operating Advisor Annual Report or (B) in connection with a recommendation by the Operating Advisor to replace
the Special Servicer. Each party to this Agreement that receives “Privileged Information” from the Operating Advisor
with a notice stating that such information is Privileged Information shall not disclose such Privileged Information to any Person
without the prior written consent of the Special Servicer and, unless a Control Termination Event has occurred, the Directing Certificateholder
(with respect to any Mortgage Loan other than a Non-Serviced Whole Loan and other than an Excluded Loan) other than pursuant to
a Privileged Information Exception. In addition and for the avoidance of doubt, while the Operating Advisor may serve in a similar
capacity with respect to Other Securitizations that involve the same parties or borrower involved in this securitization, the knowledge
of the Operating Advisor gained from performing operating advisor functions for such Other Securitizations are not imputed to the
Operating Advisor performing the obligations hereunder.


 






     -339-


     


    

 


Notwithstanding
the foregoing, the Operating Advisor shall be permitted to share Privileged Information with its Affiliates and any subcontractors
of the Operating Advisor that agree in writing to be bound by the same confidentiality provisions applicable to the Operating
Advisor.


 


(g)         Subject to the requirements of confidentiality imposed on the Operating Advisor herein (including without limitation in
respect of Privileged Information), the Operating Advisor shall respond to Inquiries proposed by Privileged Persons from time to
time in accordance with the terms of Section 4.07(a).


 


(h)         As
compensation for its activities hereunder, the Operating Advisor shall be entitled to receive the Operating Advisor Fee on
each Distribution Date with respect to each Mortgage Loan, Trust Subordinate Companion Loan or REO Mortgage Loan. As to each
Mortgage Loan, each REO Loan and each Trust Subordinate Companion Loan, the Operating Advisor Fee shall accrue from time to
time at the Operating Advisor Fee Rate and shall be computed on the basis of the Stated Principal Balance of such
Mortgage Loan, REO Mortgage Loan or Trust Subordinate Companion Loan, as the case may be, and in the same manner as interest
is calculated on the related Mortgage Loan, REO Mortgage Loan or Trust Subordinate Companion Loan, as the case may be, and,
in connection with any partial month interest payment, for the same period respecting which any related interest payment due
on the related Mortgage Loan or Trust Subordinate Companion Loan or deemed to be due on such REO Mortgage Loan is computed.
The Operating Advisor Fee shall be payable from funds on deposit in the Collection Account as provided in Section 3.05(a)(ii)
of this Agreement.


 


The Operating Advisor shall be
entitled to reimbursement of any Operating Advisor Expenses provided for pursuant to Section 6.04(a) and/or 6.04(b)
hereof, such amounts to be reimbursed from amounts on deposit in the Collection Account as provided by Section 3.05(a).
Each successor Operating Advisor shall be required to acknowledge and agree to the terms of the preceding sentence.


 


In addition, the Operating Advisor
Consulting Fee shall be payable to the Operating Advisor with respect to each Major Decision for which the Operating Advisor has
consultation obligations hereunder. The Operating Advisor Consulting Fee shall be payable from funds on deposit in the Collection
Account as provided in Section 3.05(a)(ii) of this Agreement, but, with respect to the period when the outstanding
Certificate Balances of the Control Eligible Certificates have not been reduced to zero as a result of the allocation of Realized
Losses to such Certificates, only to the extent such Operating Advisor Consulting Fee is actually received from the related Mortgagor;
provided, however, that to the extent such Operating Advisor Consulting Fee is incurred after the outstanding Certificate
Balances of the Control Eligible Regular Interests have been reduced to zero as a result of the allocation of Realized Losses to
such Certificates, such Operating Advisor Consulting Fee shall be payable in full to the Operating Advisor as a Trust Fund expense.
When the Operating Advisor has consultation obligations with respect to a Major Decision under this Agreement, the Master Servicer
or the Special Servicer, as the case may be, shall use commercially reasonable efforts to collect the applicable Operating Advisor
Consulting Fee from the related Mortgagor in connection with such Major Decision that are consistent with the efforts that the
Master Servicer


 






     -340-


     


    

 


or
the Special Servicer processing the Major Decision would use to collect any Mortgagor-paid fees owed to it in accordance with
the Servicing Standard, but only to the extent not prohibited by the related Mortgage Loan documents. The Master Servicer or Special
Servicer, as the case may be, may waive or reduce the amount of any Operating Advisor Consulting Fee payable by the related Mortgagor
if it determines that such full or partial waiver is in accordance with the Servicing Standard, but in no event shall the Master
Servicer or the Special Servicer take any enforcement action with respect to the collection of such Operating Advisor Consulting
Fee other than requests for collection; provided that the Master Servicer or the Special Servicer, as applicable, shall
consult, on a non-binding basis, with the Operating Advisor prior to any such waiver or reduction. Notwithstanding the foregoing,
the Operating Advisor will have no obligations or consultation rights as Operating Advisor with respect to: (i) any Non-Serviced
Whole Loan or any related REO Property or (ii) with respect to any Serviced AB Whole Loan, prior to the occurrence and continuance
of an AB Control Appraisal Period; provided, further, that the Operating Advisor shall not be entitled to an Operating
Advisor Consulting Fee with respect to any Non-Serviced Whole Loan.


 


(i)          After the occurrence and during the continuance of a Consultation Termination Event, the Operating Advisor may be removed
upon (i) the written direction of Certificateholders evidencing not less than 25% of the Voting Rights (taking into account
the application of Appraisal Reduction Amounts to notionally reduce the Certificate Balances of Classes to which such Appraisal
Reduction Amounts are allocable) requesting a vote to replace the Operating Advisor with a replacement Operating Advisor selected
by such Certificateholders (provided that the proposed replacement Operating Advisor is an Eligible Operating Advisor),
and (ii) payment by such requesting Holders to the Certificate Administrator of all reasonable fees and expenses to be incurred
by the Certificate Administrator in connection with administering such vote. The Certificate Administrator shall promptly provide
written notice to all applicable Certificateholders of such request by posting such notice on the Certificate Administrator’s
Website in accordance with Section 3.13(b), and concurrently by mail, and conduct the solicitation of votes of all
applicable Certificates in such regard. Upon the vote or written direction of Holders of at least 75% of the Voting Rights (taking
into account the application of Appraisal Reduction Amounts to notionally reduce the Certificate Balances of Classes to which such
Appraisal Reduction Amounts are allocable), the Trustee shall immediately replace the Operating Advisor with the replacement operating
advisor.


 


(j)          After the occurrence of an Operating Advisor Termination Event, the Trustee may, and upon the written direction of Certificateholders
representing at least 25% of the Voting Rights (taking into account the application of any Appraisal Reduction Amounts to notionally
reduce the Certificate Balance of the Classes of Certificates), the Trustee shall promptly terminate the Operating Advisor for
cause and appoint a replacement operating advisor that is an Eligible Operating Advisor; provided that no such termination
shall be effective until a successor operating advisor has been appointed and has assumed all of the obligations of the Operating
Advisor under this Agreement; provided, further, that no such termination shall terminate the rights of the Operating
Advisor that accrued prior to such termination, including accrued and unpaid compensation and indemnification rights. The Trustee
may rely on a certification by the replacement operating advisor that it is an Eligible Operating Advisor. If the Trustee is unable
to find a replacement operating advisor that is an Eligible Operating Advisor within thirty (30) days of the termination of the
Operating Advisor, the Depositor shall be


 






     -341-


     


    

 


permitted
to find a replacement. Upon any termination of the Operating Advisor and appointment of a successor to the Operating Advisor,
the Trustee will, as soon as possible, be required to give written notice of the termination and appointment to the Special Servicer,
the Master Servicer, the Certificate Administrator, the 17g-5 Information Provider (for posting to the 17g-5 Information Provider’s
Website), the Depositor, the Directing Certificateholder (only for so long as no Consultation Termination Event has occurred and
is continuing), the Risk Retention Consultation Party, any Companion Holder and the Certificateholders.


 


(k)         The holders of Certificates representing at least 25% of the Voting Rights affected by any Operating Advisor Termination
Event hereunder may waive such Operating Advisor Termination Event within twenty (20) days of the receipt of notice from the Certificate
Administrator of the occurrence of such Operating Advisor Termination Event. Upon any such waiver of an Operating Advisor Termination
Event, such Operating Advisor Termination Event shall cease to exist and shall be deemed to have been remedied for every purpose
hereunder. Upon any such waiver of an Operating Advisor Termination Event by Certificateholders, the Trustee and the Certificate
Administrator will be entitled to recover all costs and expenses incurred by it in connection with enforcement action taken with
respect to such Operating Advisor Termination Event prior to such waiver from the Trust.


 


(l)          Prior to the occurrence and continuance of a Control Termination Event, the Directing Certificateholder shall have the right
to consent, such consent not to be unreasonably withheld, conditioned or delayed, to the identity of any replacement Operating
Advisor appointed pursuant to this Section 3.26; provided, further, that such consent will be deemed
to have been granted if no objection is made within ten (10) Business Days following the Directing Certificateholder’s
receipt of the request for consent and, if granted or deemed granted, such consent cannot thereafter be revoked or withdrawn.


 


(m)        The Operating Advisor may resign from its obligations and duties hereby imposed on it (a) upon thirty (30) days prior
written notice to the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Asset
Representations Reviewer, the Directing Certificateholder and the Risk Retention Consultation Party, if applicable, if the Operating
Advisor has secured a replacement operating advisor that is an Eligible Operating Advisor and (b) upon the appointment of,
and the acceptance of such appointment by, a successor Operating Advisor that is an Eligible Operating Advisor. No such resignation
by the Operating Advisor shall become effective until the replacement Operating Advisor shall have assumed the resigning Operating
Advisor’s responsibilities and obligations. The resigning Operating Advisor shall pay all costs and expenses (including costs
and expenses incurred by the Trustee and the Certificate Administrator) associated with a transfer of its duties pursuant to this
Section 3.26.


 


(n)         In the event the Operating Advisor resigns or is otherwise terminated for any reason it shall remain entitled to any accrued
and unpaid Operating Advisor Fees and Operating Advisor Consulting Fees and reimbursement of accrued and unpaid Operating Advisor
Expenses pursuant to Section 3.26(h) and shall also remain entitled to any rights of indemnification provided hereunder.


 






     -342-


     


    

 


(o)         The parties hereto agree, and the Certificateholders by their acceptance of their Certificates shall be deemed to have agreed,
that (i) subject to Section 6.04, the Operating Advisor shall have no liability to any Certificateholder for any
actions taken or for refraining from taking any actions under this Agreement, (ii) the Operating Advisor shall act solely
as a contracting party to the extent set forth in this Agreement, (iii) the Operating Advisor shall have no (A) fiduciary
duty, or (B) other duty except with respect to its specific obligations under this Agreement, and shall have no duty to any particular
Class of Certificates or particular Certificateholders, and (iv) the Operating Advisor does not constitute an “investment
adviser” within the meaning of the Investment Advisers Act of 1940, as amended.


 


(p)         The Operating Advisor will be permitted to delegate its duties to agents or subcontractors so long as the related agreements
or arrangements with such agents or subcontractors are consistent with the provisions of this Agreement; provided that no
agent or subcontractor may (i) be affiliated with a Mortgagor, Sponsor, Master Servicer, the Special Servicer, the Depositor,
the Certificate Administrator, the Trustee, the Directing Certificateholder or any of their respective Affiliates or (ii) have
been paid any fees, compensation or other remuneration by an Underwriter, Master Servicer, the Special Servicer, the Depositor,
the Certificate Administrator, the Trustee, the Directing Certificateholder or any of their respective Affiliates in connection
with due diligence or other services with respect to any Mortgage Loan or Trust Subordinate Companion Loan prior to the Closing
Date. Notwithstanding the foregoing sentence, the Operating Advisor shall remain obligated and primarily liable for its obligations
hereunder in accordance with the provisions of this Agreement without diminution of such obligation or liability or related obligation
or liability by virtue of such delegation or arrangements or by virtue of indemnification from any Person acting as its agents
or subcontractor to the same extent and under the same terms and conditions as if the Operating Advisor alone were performing its
obligations under this Agreement. The Operating Advisor shall be entitled to enter into an agreement with any agent or subcontractor
providing for indemnification of the Operating Advisor by such agent or subcontractor, and nothing contained in this Agreement
shall be deemed to limit or modify such indemnification.


 


Section 3.27       
Companion Paying Agent. (a)  With respect to each of the Serviced Companion Loans, the Master Servicer
shall be the Companion Paying Agent hereunder. The Companion Paying Agent undertakes to perform such duties and only such duties
as are specifically set forth in this Agreement.


 


(b)         No provision of this Agreement shall be construed to relieve the Companion Paying Agent from liability for its negligent
failure to act, bad faith or its own willful misfeasance; provided, however, that the duties and obligations of the
Companion Paying Agent shall be determined solely by the express provisions of this Agreement. The Companion Paying Agent shall
not be liable except for the performance of such duties and obligations, no implied covenants or obligations shall be read into
this Agreement against the Companion Paying Agent. In the absence of bad faith on the part of the Companion Paying Agent, the Companion
Paying Agent may conclusively rely, as to the truth and correctness of the statements or conclusions expressed therein, upon any
resolutions, certificates, statements, opinions, reports, documents, orders or other instrument furnished to the Companion Paying
Agent by any Person and which on their face do not contradict the requirements of this Agreement.


 






     -343-


     


    

 


(c)         In the case of each of the Serviced Companion Loans, upon the resignation or removal of the Master Servicer pursuant to
ARTICLE VII of this Agreement, the Master Servicer, as the Companion Paying Agent, shall be deemed simultaneously to
resign or be removed.


 


(d)         This Section 3.27 shall survive the termination of this Agreement or the resignation or removal of the Companion
Paying Agent, as regards to rights accrued prior to such resignation or removal.


 


Section 3.28       
Companion Register. The Companion Paying Agent shall maintain a register (the “Companion Register”)
with respect to each Serviced Companion Loan on which it will record the names and address of, and wire transfer instructions for,
the Companion Holders from time to time, to the extent such information is provided in writing to it by each Companion Holder.
The initial Companion Holders, along with their respective name and address, are listed on Exhibit S hereto. In the
event a Companion Holder transfers a Companion Loan without notice to the Companion Paying Agent, the Companion Paying Agent shall
have no liability for any misdirected payment in such Companion Loan and shall have no obligation to recover and redirect such
payment.


 


The Companion Paying Agent shall
promptly provide the name and address of the Companion Holder to any party hereto or any successor Companion Holder upon written
request and any such Person may, without further investigation, conclusively rely upon such information. The Companion Paying Agent
shall have no liability to any Person for the provision of any such name and address.


 


For the avoidance of doubt, any
notices or information required to be delivered pursuant to this Agreement by any party hereto to a Companion Holder with respect
to a Companion Loan that has been included in an Other Securitization shall be provided to the Other Servicer (which, unless required
by the related Intercreditor Agreement to be sent to additional parties, shall be satisfied by the delivery to the “master
servicer” under the related Other Pooling and Servicing Agreement) under the Other Pooling and Servicing Agreement.


 


Section 3.29       
Certain Matters Relating to the Non-Serviced Mortgage Loans. (a)  In the event that any of the applicable
Non-Serviced Trustee, the applicable Non-Serviced Master Servicer or the applicable Non-Serviced Special Servicer shall be replaced
in accordance with the terms of the applicable Non-Serviced PSA, the Master Servicer and the Special Servicer shall acknowledge
its successor as the successor to the applicable Non-Serviced Trustee, the applicable Non-Serviced Master Servicer or the applicable
Non-Serviced Special Servicer, as the case may be.


 


(b)         If any of the Trustee, the Certificate Administrator or the Master Servicer receives notice from a Rating Agency that the
Master Servicer is no longer an “approved” master servicer by any of the Rating Agencies rating the Certificates, then
the Trustee, the Certificate Administrator or the Master Servicer, as applicable, shall promptly notify each Non-Serviced Master
Servicer of the same.


 






     -344-


     


    

 


(c)         In connection with the securitization of each Serviced Pari Passu Companion Loan, (in each case, only while it is a Serviced
Companion Loan), upon the request of (and at the expense of) the related Serviced Companion Noteholder (or its designee), each
of the Master Servicer, the Special Servicer and the Trustee, as applicable, shall use reasonable efforts to cooperate with such
Serviced Companion Noteholder in attempting to cause the related Mortgagor to provide information relating to such Whole Loan and
the related notes, and that such holder reasonably determines to be necessary or appropriate, for inclusion in any disclosure document(s)
relating to such Other Securitization.


 


(d)         In connection with the sale of any Non-Serviced Whole Loan by any Non-Serviced Special Servicer, upon receipt of any notices
or materials required to be furnished by the Non-Serviced Special Servicer to the holder of the related Non-Serviced Mortgage Loan
pursuant to the related Intercreditor Agreement, the Special Servicer shall, prior to the occurrence and continuance of a Control
Termination Event, forward such materials to the Directing Certificateholder for its consent, if such consent is required. The
Special Servicer may (with the consent of the Directing Certificateholder prior to the occurrence and continuance of a Control
Termination Event) waive any timing or delivery requirements related to such sale to the extent set forth in the related Intercreditor
Agreement.


 


(e)         With respect to any Non-Serviced Mortgage Loan, the Directing Certificateholder, prior to the occurrence and continuance
of a Consultation Termination Event, or the Special Servicer, following the occurrence and during the continuance of a Consultation
Termination Event, shall be entitled to exercise any consultation rights held by the holder of such Mortgage Loan in its capacity
as a “Non-Controlling Note Holder” (or similar term identified in the related Intercreditor Agreement) under the related
Intercreditor Agreement.


 


(f)          With respect to each Non-Serviced Mortgage Loan and Serviced Whole Loan, this Agreement is subject to the related Intercreditor
Agreement and incorporates by reference all provisions required to be included herein pursuant to such Intercreditor Agreement.


 


(g)         [Reserved].


 


(h)         [Reserved].


 


(i)          On the Servicing Shift Securitization Date, (i) the Custodian shall, upon receipt of a Request for Release transfer the
related Mortgage File (other than the note(s) designating the related Servicing Shift Mortgage Loan), the original of which shall
be retained by the Custodian) for the related Servicing Shift Whole Loan to the related Non-Serviced Trustee under the related
Non-Serviced PSA and retain a copy of such Mortgage File and (ii) the Master Servicer shall, upon receipt of notice from the Mortgage
Loan Seller that the applicable Servicing Shift Lead Note has been or is being securitized on the related Servicing Shift Securitization
Date, transfer (and cooperate with reasonable requests in connection with such transfer of) the Servicing File for the related
Servicing Shift Whole Loan, and any Escrow Payments, reserve funds and originals of items specified in clauses (9), (12), (14)

     -345-


     


    

 


Upon receipt of notice from the
Mortgage Loan Seller that the applicable Servicing Shift Lead Note has been or is being securitized on the related Servicing Shift
Securitization Date, the Master Servicer shall provide the Custodian with a Request for Release of the Mortgage File on the related
Servicing Shift Securitization Date and transfer (and cooperate with reasonable requests in connection with such transfer of) the
Servicing File to the related Non-Serviced Master Servicer identified to it pursuant to the related notice from the related Mortgage

Delivery of Excluded Information to the Certificate Administrator. Any
Excluded Information that the Master Servicer, the Special Servicer or the Operating Advisor identifies and delivers to the Certificate
Administrator for posting to the Certificate Administrator’s Website shall be delivered to the Certificate Administrator
via e-mail (or such other electronic means as is mutually acceptable to the parties) in one or more separate files labeled “Excluded

of doubt, any information that is not appropriately labeled and delivered in accordance with this Section 3.30 shall
not be separately posted as Excluded Information on the Certificate Administrator’s Website, and any information appropriately

When so posted, the Excluded Controlling Class Holders shall be prohibited from the access of Excluded Information with respect
to any Excluded Controlling Class Loans on the Certificate Administrator’s Website (unless a loan-by-loan segregation is
later performed by the Certificate Administrator in which case such access shall only be prohibited with respect to the related
Excluded Controlling Class Loans). None of the Master Servicer, the Special Servicer or the Operating Advisor shall have any obligations
to separately label and deliver any Excluded Information in accordance with this Section 3.30 until such party has
received written notice with respect to the related Excluded Controlling Class Loan in the form of Exhibit P-1B to this
Agreement. Nothing set forth in this Agreement shall prohibit the Directing Holder or any Controlling Class Certificateholder
from receiving, requesting or reviewing any Excluded Information relating to any Excluded Controlling Class Loan with respect
to which the Directing Holder or such Controlling Class Certificateholder is not a Borrower Party and, if such Excluded Information
is not available on the Certificate Administrator’s Website, such Directing Holder or Controlling Class Certificateholder
that is not a Borrower Party with respect to the related Excluded Controlling Class Loan shall be permitted to obtain such information
in accordance with Section 3.13(a).

Administrator’s
Website, such Directing Certificateholder or Controlling Class Certificateholder that is not a Borrower Party with respect
to the related Excluded Controlling Class Loan shall be permitted to obtain such information in accordance with Section 4.02(f)
of this Agreement.


 


Section 3.31       
Trust Subordinate Companion Loans.


 


(a)         With respect to the Trust Subordinate Companion Loans, references to actions being taken for the benefit of any such Companion
Loan or in the best interests of the holders of the related Loan-Specific Certificates in this Agreement shall be deemed to be
taken (and subject to the same considerations) also for the benefit of, or to be taken in the best interests of, the holders of
such Loan-Specific Certificates, as beneficial owners of the related Trust Subordinate Companion Loan.


 


(b)         Any notices, reports or other information related to a Trust Subordinate Companion Loan required to be delivered by a party
under this Agreement or the related Intercreditor Agreement to the holders of the related Loan-Specific Certificates or the holder
of such Trust Subordinate Companion Loan shall be delivered (in lieu of delivery to such holders) to the applicable Directing Holder
by such party within the same time periods as such notices, reports or other information are required to be delivered to the holder
of such Trust Subordinate Companion Loan.


 


(c)         Any consents required to be obtained from the holder of a Trust Subordinate Companion Loan under this Agreement or the related
Intercreditor Agreement or any obligation under this Agreement or the related Intercreditor Agreement of the Master Servicer or
the Special Servicer or other party to this Agreement to consult with or obtain the consent of or follow the direction of the holder
of such Trust Subordinate Companion Loan shall instead be deemed to require such Person to consult with, obtain the consent of
or follow the direction of the applicable Directing Holder.


 


(d)         Any rights exercisable by the holder of the Standard Highline Non-Trust Junior Subordinate Companion Loan under this Agreement
or the Standard Highline Intercreditor Agreement with respect to the exercise of any right to replace the Special Servicer with
respect to The Standard Highline NYC Whole Loan, cure rights, rights to post “threshold collateral” or purchase option
rights shall be exercisable by the holder of the Standard Highline Non-Trust Junior Subordinate Companion Loan (as the initial
the Standard Highline Directing Holder) prior to a Standard Highline Non-Trust Junior Subordinate Companion Loan Control Appraisal
Period and any amounts payable, or actions required to be taken in connection with such exercise, shall be payable from or taken
by such Standard Highline Directing Holder, as applicable. With respect to The Standard Highline NYC Whole Loan, subject to the
foregoing and applicable REMIC Provisions, the Standard Highline Directing Holder may direct the Master Servicer or the Special
Servicer, on behalf of the Trustee and the holders of the Standard Highline Loan-Specific Certificates to implement the holder
of the Standard Highline Non-Trust Subordinate Companion Loans’ or the holder of the Standard Highline Trust Subordinate
Companion Loan’s, as applicable, exercise of any rights, to the extent that each such holder is entitled to such rights under
the Standard Highline Intercreditor Agreement. For the avoidance of doubt, in no event shall the Master Servicer or the Special
Servicer be required to advance any cure payment or purchase price due under the Standard Highline Intercreditor Agreement.

(e)         With respect to any Trust Subordinate Companion Loan, prior to the Special Servicer (i) obtaining the consent of, or consulting
with the applicable Directing Holder to the extent provided for under the related Intercreditor Agreement, (ii) delivering any
Asset Status Report to such Directing Holder, or (iii) permitting the exercise of any cure rights, if any, in accordance with the
related Intercreditor Agreement, such Directing Holder shall have delivered to the Special Servicer an officer’s certificate

Loan, REO Loan or Trust Subordinate Companion Loan during the related Collection Period, in each case
net of any Liquidation Fees payable therefrom, shall be distributable as follows: if, during any particular Collection Period,
any Yield Maintenance Charge is collected and allocable with respect to any Mortgage Loan, then on the Distribution Date corresponding
to that Collection Period, the Certificate Administrator shall pay that Yield Maintenance Charge in the following manner: (a) pro
rata, between (i) the group (the “YM Group A”) of Class A-1, Class A-2, Class A-3, Class A-4, Class A-5,
Class A-SB, Class X-A and Class A-S Regular Interests, and (ii) the group (the “YM Group B” and collectively
with the YM Group A, the “YM Groups”) of Class X-B, Class B, Class C and Class D Regular Interests, based upon
the aggregate amount of principal distributed to the Classes of Pooled Regular Interests in each YM Group on such Distribution
Date; and (b) as among the respective Classes of Pooled Regular Interests in each YM Group in the following manner: (1) on a pro
rata basis in accordance with their respective entitlements in those Yield Maintenance Charges, to each Class of Pooled Regular
Interests (other than Class X Regular Interests) in such YM Group in an amount equal to the product of (x) a fraction whose numerator
is the amount of principal distributed to such Regular Interests on such Distribution Date and whose denominator is the total amount
of principal distributed to all of the Pooled Regular Interests (other than Class X Regular Interests) in such YM Group on such
Distribution Date, (y) the Base Interest Fraction for the related principal prepayment with respect to such Class of Pooled Regular
Interests, and (z) the aggregate amount of such Yield Maintenance Charge allocated to such YM Group and (2) the portion of such
Yield Maintenance Charge allocated to such YM Group remaining after such distributions to the applicable Class(es) of Pooled Regular
Interests in such YM Group, in the case of amounts distributable to YM Group A, to the Class X-A Regular Interest and in the case
of amounts distributable to YM Group B, to the Class X-B Regular Interest. Any Yield Maintenance Charges received and allocable
with respect to a Trust Subordinate Companion Loan shall be distributed to the related Loan-Specific Regular Interests.


 


For purposes of the first
paragraph of this Section 4.01(i), the relevant “Base Interest Fraction” in connection with any Principal
Prepayment of any Mortgage Loan that provides for the payment of a Yield Maintenance Charge, and with respect to any principal
prepayment on any Mortgage Loan and with respect to any Class of Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB,
Class A-S, Class B, Class C and Class D Regular Interests is a fraction (a) whose numerator is the greater of (x) zero and (y)
the difference between (i) the Pass-Through Rate of such Class of Regular Interests and (ii) the discount rate used in accordance
with the related Mortgage Loan documents in calculating the Yield Maintenance Charge with respect to such principal prepayment
and (b) whose denominator is the greater of zero and the difference between (i) the Mortgage Rate on such Mortgage Loan (or with
respect to any Mortgage Loan that is part of a Serviced Whole Loan, the Mortgage Rate of such Serviced Whole Loan) and (ii) the
discount rate used in accordance with the related Mortgage Loan documents in calculating the Yield Maintenance Charge with respect
to such principal prepayment; provided, however, that under no circumstances shall the Base Interest Fraction be
greater than 1.0 or less than zero. If such discount rate is greater than or equal to the lesser of (x) the Mortgage Rate on the
related Mortgage Loan or Serviced Whole Loan, as applicable, and (y) the Pass-Through Rate described in the preceding sentence,
then the Base Interest Fraction shall equal zero; provided that if such discount rate is greater than or equal to the Mortgage
Rate on such Mortgage Loan or Serviced Whole Loan, as applicable, but less than the Pass-Through Rate described in the preceding
sentence, then the Base Interest Fraction shall equal 1.0. If a


 



     -379-


     


    

 


Mortgage Loan provides for a step-up in the Mortgage Rate, then
the Mortgage Rate used in the determination of the Base Interest Fraction shall be the Mortgage Rate in effect at the time of the
prepayment.


 


For purposes of the preceding
paragraph, the relevant “Discount Rate” in connection with any Yield Maintenance Charge collected on any prepaid
Mortgage Loan or REO Loan and distributable on any Distribution Date shall be a rate per annum equal to (i) if a discount
rate was used in the calculation of the applicable Yield Maintenance Charge pursuant to the terms of the relevant Mortgage Loan
or REO Loan, as the case may be, such discount rate (as reported by the Master Servicer), converted (if necessary) to a monthly
equivalent yield, or (ii) if a discount rate was not used in the calculation of the applicable Yield Maintenance Charge pursuant
to the terms of the relevant Mortgage Loan or REO Loan, as the case may be, the yield calculated by the linear interpolation of
the yields (as reported under the heading “U.S. Government Securities/Treasury Constant Maturities” in Federal Reserve
Statistical Release H.15 (519) published by the Federal Reserve Board for the week most recently ended before the date of the relevant
prepayment (or deemed prepayment) of U.S. Treasury constant maturities with a maturity date, one longer and one shorter, most nearly
approximating the related Stated Maturity Date (in the case of a Mortgage Loan or REO Loan that is not related to an ARD Loan)
or the related Anticipated Repayment Date (in the case of a Mortgage Loan or REO Loan that is related to an ARD Loan)), such interpolated
yield converted to a monthly equivalent yield. If Federal Reserve Statistical Release H.15 (519) is no longer published, the Master
Servicer shall select a comparable publication as the source of the applicable yields of U.S. Treasury constant maturities, and
the Master Servicer shall incur no liability with respect thereto.


 


(i)       No
Yield Maintenance Charge shall be distributed to the Holders of the Class E Regular Interest, Class F Regular Interest, Class NR
Regular Interest, Class R Certificates or Class Z Certificates. After the Certificate Balances and Notional Amounts of the Class
A-1 Regular Interest, Class A-2 Regular Interest, Class A-3 Regular Interest, Class A-4 Regular Interest, Class A-5 Regular Interest,
Class A-SB Regular Interest, Class X-A Regular Interest, Class X-B Regular Interest, Class A-S Regular Interest, Class B Regular
Interest, Class C Regular Interest and Class D Regular Interest have been reduced to zero, Yield Maintenance Charges with respect
to the Mortgage Loans shall be distributed to the Holder of the Class X-B Regular Interest.


 


(ii)      All
distributions of Yield Maintenance Charges made (i) in respect of the respective Classes of Pooled Regular Interests on each Distribution
Date pursuant to Section 4.01(i) shall first be deemed to be distributed from the Lower-Tier REMIC to the Upper-Tier REMIC
in respect of the Lower-Tier Regular Interests, pro rata based upon the amount of principal distributed in respect of each
such Class of Lower-Tier Regular Interests for such Distribution Date pursuant to Section 4.01(i) above; (ii) in respect
of the Y&L Towers Loan-Specific Certificates on each Distribution Date pursuant to Section 4.01(i) shall first be deemed
to be distributed from the Y&L Towers Trust Subordinate Companion Loan REMIC Distribution Account to the Upper-Tier REMIC in
respect of the Y&L Towers Companion Loan REMIC Regular Interests, pro rata based on the amount of principal distributed
in respect of each such Class of Y&L Towers Companion Loan REMIC Regular Interests for such Distribution Date pursuant to Section
4.01(i) and (iii) in respect of the Standard Highline Loan-Specific Certificates on


 



     -380-


     


    

 


each Distribution Date pursuant to Section
4.01(i) shall first be deemed to be distributed from the Standard Highline Trust Subordinate Companion Loan REMIC Distribution
Account to the Upper-Tier REMIC in respect of the Standard Highline Companion Loan REMIC Regular Interests, pro rata based
on the amount of principal distributed in respect of each such Class of the Standard Highline Companion Loan REMIC Regular Interests
for such Distribution Date pursuant to Section 4.01(i).


 


(iii)     On
each Distribution Date, any Yield Maintenance Charges payable in respect of the Yorkshire & Lexington Towers Whole Loan
and received during the related Collection Period and allocable in respect of the Y&L Towers Trust Subordinate Companion
Loan pursuant to the Y&L Towers Intercreditor Agreement shall be distributed to the Y&L Towers Loan-Specific
Certificates by the Certificate Administrator in the following manner: (i) first, to the holders of the Class UES-A, Class
UES-B, Class UES-C and Class UES-D Certificates in an amount equal to the product of (x) a fraction whose numerator is the
amount of principal distributed to such class of Y&L Towers Loan-Specific Certificates on such Distribution Date and
whose denominator is the total amount of principal distributed to the holders of the Class UES-A, Class UES-B, Class UES-C
and Class UES-D Certificates on such Distribution Date, (y) the Y&L Towers Base Interest Fraction for the related
principal prepayment and such class of Y&L Towers Loan-Specific Certificates and (z) the aggregate amount of such Yield
Maintenance Charges allocated to the Y&L Towers Trust Subordinate Companion Loan and (ii) then, the portion of such yield
maintenance charge remaining after such distributions to the Class UES-A, Class UES-B, Class UES-C and Class
UES-D Certificates, to the holders of the Class UES-X Certificates. If there is more than one Class of Y&L Towers Loan-Specific
Certificates entitled to distributions of principal on any particular Distribution Date on which Yield Maintenance Charges
are distributable to such Class(es) of Certificates, the aggregate amount of such Yield Maintenance Charges will be allocated
among all such Classes of Y&L Towers Loan-Specific Certificates up to, and on a pro rata basis in accordance with,
their respective entitlements in those Yield Maintenance Charges in accordance with the first sentence of this paragraph. If
any Yield Maintenance Charges remain undistributed after the distributions referred to above have been made, such
remaining amounts will be distributed to the Holders of the Class UES-A, Class UES-B, Class UES-C and Class UES-D
Certificates pro rata, based upon the principal distributions allocated to such Classes for such period.


 


(iv)    On
each Distribution Date, any Yield Maintenance Charges payable in respect of The Standard Highline NYC Whole Loan and
received during the related Collection Period and allocable in respect of the Standard Highline Trust Subordinate Companion

Loan-Specific Certificates by the Certificate Administrator in the following manner: (i) first, to the holders of the Class
STN-A, Class STN-B and Class STN-C Certificates in an amount equal to the product of (x) a fraction whose numerator is the
amount of principal distributed to such class of the Standard Highline Loan-Specific Certificates on such Distribution Date
and whose denominator is the total amount of principal distributed to the holders of the Class STN-A, Class STN-B and Class
STN-C Certificates on such Distribution Date, (y) the Standard Highline Base Interest Fraction for the related principal
prepayment and such class of the Standard Highline Loan-Specific Certificates and (z) the aggregate amount of such Yield
Maintenance Charges allocated to the Standard Highline Trust Subordinate

Companion Loan and (ii)
then, the portion of such yield maintenance charge remaining after such distributions to the Class STN-A, Class STN-B and
Class STN-C Certificates, to the holders of the Class STN-X Certificates. If there is more than one Class of the Standard Highline
Loan-Specific Certificates entitled to distributions of principal on any particular Distribution Date on which Yield
Maintenance Charges are distributable to such Class(es) of Certificates, the aggregate amount of such Yield Maintenance
Charges will be allocated among all such Classes of the Standard Highline Loan-Specific Certificates up to, and on a pro
rata basis in accordance with, their respective entitlements in those Yield Maintenance Charges in accordance with the
first sentence of this paragraph. If any Yield Maintenance Charges remain undistributed after the distributions referred to
above have been made, such remaining amounts will be distributed to the Holders of the Class STN-A, Class STN-B and Class
STN-C Certificates pro rata, based upon the principal distributions allocated to such Classes for such period.

in Sections 4.01(l), 4.01(m) and 9.01, all such distributions with respect to each Class on each Distribution
Date shall be made to the Certificateholders of the respective Class of record at the close of business on the related Record Date
and shall be made by wire transfer of immediately available funds to the account of any such Certificateholder at a bank or other
entity having appropriate facilities therefor, if such Certificateholder shall have provided the Certificate Administrator with
written wiring instructions no less than five (5) Business Days prior to the


 



     -384-


     


    

 


related Record Date (which wiring instructions may

at its address in the Certificate Register. The final distribution on each Certificate (determined without regard to any possible
future reimbursement of Realized Losses previously allocated to such Certificate) will be made in like manner, but only upon presentation
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Each distribution with
respect to a Book-Entry Certificate shall be paid to the Depository, as Holder thereof, and the Depository shall be responsible

and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating firm”)
for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Certificate Owners that it represents.
None of the Trustee, the Certificate Administrator, the Certificate Registrar, the Depositor, the Master Servicer, the Special
Servicer or the Underwriters shall have any responsibility therefor except as otherwise provided by this Agreement or applicable
law.


 


(l)           Except
as otherwise provided in Section 9.01, whenever the Certificate Administrator expects that the final distribution with respect
to any Class of Certificates (determined without regard to any possible future reimbursement of any amount of Realized Losses previously
allocated to such Class of Certificates) will be made on the next Distribution Date, the Certificate Administrator shall, no later
than the related P&I Advance Determination Date, post on the Certificate Administrator’s Website pursuant to Section
3.13(b) a notice in electronic format to the effect that:


 


(i)         the
Certificate Administrator expects that the final distribution with respect to such Class of Certificates will be made on such Distribution
Date but only upon presentation and surrender of such Certificates at the offices of the Certificate Registrar or such other location
therein specified; and


 


(ii)        no
interest shall accrue on such Certificates from and after such Distribution Date.


 


Any funds not distributed to any Holder
or Holders of Certificates of such Class on such Distribution Date because of the failure of such Holder or Holders to tender their
Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section 4.01(l)
shall not have been surrendered for cancellation within six (6) months after the time specified in such notice, the Certificate
Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for
cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such
Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or through an agent, shall
take such steps to contact the remaining non-tendering Certificateholders concerning the surrender of their Certificates as it
shall deem appropriate and subject to escheatment and other


 



     -385-


     


    

 


applicable laws. The costs and expenses of holding such funds in trust
and of contacting such Certificateholders following the first anniversary of the delivery of such second notice to the non-tendering
Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder on any amount
held in trust hereunder by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its
Certificate(s) for final payment thereof in accordance with this Section 4.01(l).


 


(m)         Distributions
in reimbursement of Realized Losses previously allocated to the Regular Certificates shall be made in the amounts and manner specified
in Section 4.01(a), Section 4.01(b), Section 4.01(c), Section 4.01(d) or Section 4.01(g), as
applicable, to the Holders of the respective Class otherwise entitled to distributions of interest and principal on such Class
on the relevant Distribution Date; provided that all distributions in reimbursement of Realized Losses previously allocated
to a Class of Certificates which has since been retired shall be to the prior Holders that surrendered the Certificates of such
Class upon retirement thereof and shall be made by check mailed to the address of each such prior Holder last shown in the Certificate
Register. Notice of any such distribution to a prior Holder shall be made in accordance with Section 13.05 at such last
address. The amount of the distribution to each such prior Holder shall be based upon the aggregate Percentage Interest evidenced
by the Certificates surrendered thereby. If the check mailed to any such prior Holder is returned uncashed, then the amount thereof
shall be set aside and held uninvested in trust for the benefit of such prior Holder, and the Certificate Administrator shall attempt
to contact such prior Holder in the manner contemplated by Section 4.01(l) as if such Holder had failed to surrender its
Certificates.


 


(n)          On
each Distribution Date, any Excess Interest received during the related Collection Period with respect to the Mortgage Loans shall
be distributed to the Holders of the Class V1-Z, Class V2-Z and Class Z Certificates from the Excess Interest Distribution Account.

as set forth in the prior sentence.

(i)         to

Certificate Administrator or any of their directors, officers, employees and agents, as the case may be, any amounts payable or
reimbursable to any such Person pursuant to Section 8.05, to the extent any such amounts relate solely to a Serviced Whole
Loan related to such Companion Loan, and such amounts are to be paid by the related Companion Holder pursuant to the related Intercreditor
Agreement;


 






     -386-


     


    




 


(iii)       to
pay all amounts remaining in the Companion Distribution Account related to such Serviced Companion Loan to the related Companion
Holder, in accordance with the related Intercreditor Agreement; and


 


(iv)       to
clear and terminate the Companion Distribution Account at the termination of this Agreement pursuant to Section 9.01.


 


All distributions from
the Companion Distribution Account required hereunder shall be made by the Companion Paying Agent to the related Companion Holder
by wire transfer in immediately available funds on the Serviced Whole Loan Remittance Date to the account of such Companion Holder
or an agent therefor appearing on the Companion Register on the related Record Date (or, if no such account so appears or information
relating thereto is not provided at least five Business Days prior to the related Record Date, by check sent by first class mail
to the address of such Companion Holder or its agent appearing on the Companion Register). Any such account shall be located at
a commercial bank in the United States.


 


On the final Master Servicer
Remittance Date, the Master Servicer shall withdraw from the Collection Account and deliver to the Certificate Administrator who
shall distribute to the Mortgage Loan Sellers, any Loss of Value Payments relating to the Mortgage Loans that it is servicing and
that were transferred from the Loss of Value Reserve Fund to the Collection Account on the immediately preceding Master Servicer
Remittance Date.

(c)          Each
of the Master Servicer and the Special Servicer may, at its sole cost and expense, make available by electronic media, bulletin
board service or Internet website (in addition to making information available as provided herein) any reports or other information
the Master Servicer or the Special Servicer, as applicable, is required or permitted to provide to any party to this Agreement,
the Rating Agencies or any Certificateholder or any prospective Certificateholder that has provided the Certificate Administrator,
the Master Servicer or the Special Servicer, as applicable, with an Investor Certification or has executed a “click-through”
confidentiality agreement in accordance with Section 3.13 hereof (which may be a licensed or registered investment advisor)
to the extent such action does not conflict with the terms of this Agreement (including without limitation, any requirements to
keep Privileged Information confidential), the terms of the Mortgage Loans or applicable law. Notwithstanding this paragraph, the
availability of such information or reports on the Internet or similar electronic media shall not be deemed to satisfy any specific
delivery requirements in this Agreement except


 



     -391-


     


    

 


as set forth herein. In connection with providing access to the Master Servicer’s
or Special Servicer’s Internet website, the Master Servicer or the Special Servicer, as applicable, shall take reasonable
measures to ensure that only such parties listed above may access such information including, without limitation, requiring registration,
a confidentiality agreement and acceptance of a disclaimer. The Master Servicer or the Special Servicer, as applicable, shall not
be liable for dissemination of this information in accordance with this Agreement, and neither the Master Servicer nor the Special
Servicer shall be responsible for any information delivered, produced, or made available pursuant to Section 3.13 and 4.02(c),
other than information produced by the Master Servicer or the Special Servicer, as applicable; provided that such information
otherwise meets the requirements set forth herein with respect to the form and substance of such information or reports. The Master
Servicer shall be entitled to attach to any report provided pursuant to this subsection, any reasonable disclaimer with respect
to information provided, or any assumptions required to be made by such report.


 


The Special Servicer
shall from time to time (and, in any event, as may be reasonably required by the Master Servicer) provide the Master Servicer with
such information in its possession regarding the Specially Serviced Loans and REO Properties as may be necessary for the Master
Servicer to prepare each report and any supplemental information to be provided by the Master Servicer to the Certificate Administrator.
Neither the Certificate Administrator nor the Depositor shall have any obligation to recompute, verify or recalculate the information
provided thereto by the Master Servicer. Unless the Certificate Administrator has actual knowledge that any report or file received
from the Master Servicer contains erroneous information, the Certificate Administrator is authorized to rely thereon in calculating
and making distributions to Certificateholders in accordance with Section 4.01, preparing the Distribution Date Statement
required by Section 4.02(a) and allocating Realized Losses to the Certificates in accordance with Section 4.04.


 


Notwithstanding the foregoing,
the failure of the Master Servicer or the Special Servicer to disclose any information otherwise required to be disclosed pursuant
to this Section 4.02(c) or Section 4.02(d) shall not constitute a breach of this Section 4.02(c) or of Section
4.02(d) to the extent the Master Servicer or the Special Servicer so fails because such disclosure, in the reasonable belief
of the Master Servicer or the Special Servicer, as the case may be, would violate any applicable law or any provision of a Mortgage
Loan document prohibiting disclosure of information with respect to the Mortgage Loans or the Mortgaged Properties. The Master
Servicer or the Special Servicer may affix to any information provided by it any disclaimer it deems appropriate in its reasonable
discretion (without suggesting liability on the part of any other party hereto).

practicable, at the expense of the requesting party, the Certificate Administrator shall make available to the requesting party
such information that is in the Certificate Administrator’s possession or can reasonably be obtained by the Certificate Administrator
as is requested by such person, for purposes of satisfying applicable reporting requirements under Rule 144A under the Securities
Act. Neither the Certificate Registrar, nor


 



     -392-


     


    

 


the Certificate Administrator shall have any responsibility for the sufficiency under
Rule 144A or any other securities laws of any available information so furnished to any person including any prospective purchaser
of a Certificate or any interest therein, nor for the content or accuracy of any information so furnished which was prepared or
delivered to them by another.


 


(e)          The
information to which any Certificateholder is entitled is limited to the information gathered and provided to the Certificateholder
by the parties hereto pursuant to this Agreement and by acceptance of any Certificate, each Certificateholder agrees that except
as specifically provided herein, no Certificateholder shall contact any Mortgagor directly with respect to any Mortgage Loan.


 


(f)           Upon
the reasonable request of the Directing Holder or any Controlling Class Certificateholder that, in either case, is an Excluded
Controlling Class Holder with respect to any Excluded Controlling Class Loan identified to the Master Servicer’s (in the
case of a Non-Specially Serviced Loan) or the Special Servicer’s (in the case of a Specially Serviced Loan) reasonable satisfaction
(at the expense of the Directing Holder or such Controlling Class Certificateholder) and if such information is in the Master Servicer’s
or the Special Servicer’s possession, as applicable, the Master Servicer or the Special Servicer, shall provide or make available
(or forward electronically) to the Directing Holder or such Controlling Class Certificateholder, as applicable, (at the expense
of the Directing Holder or such Controlling Class Certificateholder, as applicable) any Excluded Information (available to Privileged
Persons through the Certificate Administrator’s Website but not accessible to the Directing Holder or such Controlling Class
Certificateholder on account of it constituting Excluded Information, as applicable, through the Certificate Administrator’s
Website because the Directing Holder or such Controlling Class Certificateholder, as applicable, is an Excluded Controlling Class
Holder with respect to another Excluded Controlling Class Loan) relating to any Excluded Controlling Class Loan with respect to
which the Directing Holder or such Controlling Class Certificateholder, as applicable, is not a Borrower Party; provided
that, in connection therewith, the Master Servicer or the Special Servicer may require a written confirmation executed by the requesting
Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special Servicer, generally to
the effect that such Person is the Directing Holder or a Controlling Class Certificateholder will keep such Excluded Information
confidential and is not a Borrower Party, upon which the Master Servicer or the Special Servicer may conclusively rely. In addition,
the Master Servicer and the Special Servicer shall be entitled to conclusively rely on delivery from the Directing Holder or a
Controlling Class Certificateholder, of an Investor Certification substantially in the form of Exhibit P-1D that such Directing
Holder or Controlling Class Certificateholder, is not an Excluded Controlling Class Holder with respect to a particular Mortgage
Loan. For the avoidance of doubt, the Special Servicer referenced in this Section 4.02(f) shall include any applicable Excluded
Special Servicer with respect to the related Excluded Special Servicer Loan(s).


 


Section
4.03     P&I Advances. (a) On or before 4:00 p.m., New York City time, on each P&I
Advance Date, the Master Servicer shall (i) remit to the Certificate Administrator for deposit from its own funds into the
(A) Lower-Tier REMIC Distribution Account, an amount equal to the aggregate amount of P&I Advances, if any, with respect
to the Mortgage Loans to be made in respect of the related Distribution Date and (B) the applicable Trust Subordinate
Companion Loan REMIC Distribution Account, an amount equal to the aggregate amount of


 



     -393-


     


    

 


 P&I Advances, if any, with respect
to the related Trust Subordinate Companion Loan to be made in respect of the related Distribution Date, (ii) apply amounts
held in the Collection Account, for future distribution to Certificateholders in subsequent months in discharge of any such
obligation to make P&I Advances or (iii) make P&I Advances in the form of any combination of (i) and (ii) aggregating
the total amount of P&I Advances to be made. Any amounts held in the Collection Account for future distribution and so
used to make P&I Advances with respect to the Mortgage Loans or the Trust Subordinate Companion Loans shall be
appropriately reflected in the Master Servicer’s records and replaced by the Master Servicer by deposit in the
Collection Account on or before the next succeeding P&I Advance Date (to the extent not previously replaced through
the deposit of Late Collections of the delinquent principal and/or interest in respect of which P&I Advances were made).
The Master Servicer shall notify the Certificate Administrator of (i) the aggregate amount of P&I Advances with respect
to the Mortgage Loans, the Trust Subordinate Companion Loans and any REO Mortgage Loans for a Distribution Date and (ii) the
amount of any Nonrecoverable P&I Advances with respect to the Mortgage Loans or the Trust Subordinate Companion Loans and
any REO Mortgage Loans for such Distribution Date. If the Master Servicer fails to make a required P&I Advance by 4:00
p.m., New York City time, on any P&I Advance Date, the Trustee shall make such P&I Advance pursuant to Section
7.05 by noon, New York City time, on the related Distribution Date, unless the Master Servicer shall have cured such
failure (and provided written notice of such cure to the Trustee and the Certificate Administrator) by 11:00 a.m., New York
City time, on such Distribution Date. In the event that the Master Servicer fails to make a required P&I Advance
hereunder, the Certificate Administrator shall notify the Trustee of such circumstances by 4:30 p.m., New York City time, on
the related P&I Advance Date. Notwithstanding the foregoing, the portion of any P&I Advance equal to the
CREFC® Intellectual Property Royalty License Fee for the related Mortgage Loans or the Trust Subordinate
Companion Loans and any REO Mortgage Loans shall not be remitted to the Certificate Administrator for deposit into the
Lower-Tier REMIC Distribution Account but shall be deposited into the Collection Account for payment to
CREFC® on such Distribution Date.


 


(b)          Subject
to Section 4.03(c) and Section 4.03(e) below, the amount of P&I Advances to be made by the Master Servicer with
respect to any Distribution Date and all Mortgage Loans, the Trust Subordinate Companion Loans and REO Mortgage Loans, shall be
equal to: (i) the Periodic Payments (net of related Servicing Fees and, in the case of any Non-Serviced Mortgage Loan, a fee accruing
at the related Non-Serviced Primary Servicing Fee Rate) other than Balloon Payments, that were due on the Mortgage Loans (including
any Non-Serviced Mortgage Loan), the Trust Subordinate Companion Loans and any REO Loan (including any portion of an REO Loan related
to a Trust Subordinate Companion Loan, but excluding any portion of an REO Loan related to any other Companion Loan) during the
related Collection Period and delinquent as of the close of business on the Business Day preceding the related P&I Advance
Date (or not advanced by any Sub-Servicer on behalf of the Master Servicer) and (ii) with respect to each Mortgage Loan or Trust
Subordinate Companion Loan delinquent in respect of its Balloon Payment as of the close of business on the Business Day preceding
the related P&I Advance Date (including any REO Loan (including any portion of a REO Loan related to the a Trust Subordinate
Companion Loan, but excluding any portion of an REO Loan related to any other Companion Loan) as to which the related Balloon Payment
would have been past due), an amount equal to the Assumed Scheduled Payment (or Y&L Towers Assumed Scheduled Payments, with
respect to the Y&L Towers Trust Subordinate Companion Loan or


 



     -394-


     


    

 


Standard Highline Assumed Scheduled Payments, with respect to
the Standard Highline Trust Subordinate Companion Loan) (net of any collections of previously unadvanced principal and interest
(adjusted to the related Net Mortgage Rate) received with respect to such Mortgage Loan, the Trust Subordinate Companion Loan or
REO Loan, as applicable, during the related Collection Period) therefor plus, without duplication, in the case of the Y&L
Towers Trust Subordinate Companion Loan, the related Y&L Towers Diverted Amount. Subject to subsection (c) below, the
obligation of the Master Servicer to make such P&I Advances is mandatory, and with respect to any Mortgage Loan (including
any Non-Serviced Mortgage Loan), the Trust Subordinate Companion Loan or REO Loan (including any portion of a REO Loan related
to the a Trust Subordinate Companion Loan but excluding any portion of an REO Loan related to any other Companion Loan), shall
continue until the Distribution Date on which the proceeds, if any, received in connection with a Liquidation Event or the disposition
of the REO Property, as the case may be, with respect thereto are to be distributed. Neither the Master Servicer nor the Trustee
shall make or be permitted to make any P&I Advances with respect to any Companion Loan other than the a Trust Subordinate Companion
Loan. The Special Servicer shall not make any P&I Advances on any Mortgage Loan or Companion Loan, including a Trust Subordinate
Companion Loan.


 


(c)          Notwithstanding
anything herein to the contrary, no P&I Advance shall be required to be made hereunder if such P&I Advance would, if made,
constitute a Nonrecoverable P&I Advance. With respect to each Non-Serviced Mortgage Loan, the Master Servicer will be required
to make its determination (based on information provided by the applicable Non-Serviced Master Servicer and Non-Serviced Special
Servicer) that it has made a P&I Advance on such Non-Serviced Mortgage Loan that is a Nonrecoverable Advance or that any proposed
P&I Advance would, if made, constitute a Nonrecoverable Advance with respect to such Non-Serviced Mortgage Loan independently
of any determination made by the applicable Non-Serviced Master Servicer or the applicable Non-Serviced Special Servicer, as the
case may be, under the applicable Non-Serviced PSA in respect of the related Non-Serviced Companion Loan. If the Master Servicer
or the Special Servicer determines that a proposed P&I Advance with respect to a Non-Serviced Mortgage Loan, if made, or any
outstanding P&I Advance with respect to a Non-Serviced Mortgage Loan previously made, would be, or is, as applicable, a Nonrecoverable
Advance, the Master Servicer shall provide the applicable Non-Serviced Master Servicer and Non-Serviced Special Servicer written
notice of such determination within two (2) Business Days of the date of such determination. If the Master Servicer receives written
notice from the related Non-Serviced Master Servicer or the related Non-Serviced Special Servicer, as the case may be, that either
has determined in accordance with the applicable Non-Serviced PSA with respect to a Non-Serviced Companion Loan, that any proposed
advance under the applicable Non-Serviced PSA that is similar to a P&I Advance would be, or any outstanding advance under such
Non-Serviced PSA that is similar to a P&I Advance is, a nonrecoverable advance, then the Master Servicer or the Trustee may,
based upon such determination, determine that any P&I Advance previously made or proposed to be made with respect to the related
Non-Serviced Mortgage Loan, will be a Nonrecoverable P&I Advance. Thereafter, in either case, the Master Servicer shall not
be required to make any additional P&I Advances with respect to the related Non-Serviced Mortgage Loan unless and until the
Master Servicer or the Trustee, as the case may be, determines that any such additional P&I Advances with respect to the related
Non-Serviced Mortgage Loan would not be a Nonrecoverable P&I Advance, which determination


 



     -395-


     


    

 


may be as a result of consultation
with the related Non-Serviced Master Servicer or the related Non-Serviced Special Servicer, as the case may be, or otherwise.


 


(d)          In
connection with the recovery of any P&I Advance out of the Collection Account, pursuant to Section 3.05(a), the Master
Servicer shall be entitled to pay the Trustee and itself (in that order of priority) as the case may be, out of any amounts then
on deposit in the Collection Account (but in no event from any funds allocable to a Serviced Companion Noteholder (unless related
thereto), except to the extent permitted pursuant to the terms of the related Intercreditor Agreement), interest at the Reimbursement
Rate in effect from time to time, accrued on the amount of such P&I Advance from the date made to but not including the date
of reimbursement; provided, however, that no interest will accrue on any P&I Advance (i) made with respect to
a Mortgage Loan or Trust Subordinate Companion Loan until after the related Due Date has passed and any applicable Grace Period
has expired or (ii) if the related Periodic Payment is received after the Determination Date but on or prior to the related P&I
Advance Date. The Master Servicer shall reimburse itself and/or the Trustee, as the case may be, for any outstanding P&I Advance,
subject to Section 3.17 of this Agreement, as soon as practicably possible after funds available for such purpose are deposited
in the Collection Account.


 


In addition, the Master
Servicer, the Special Servicer or the Trustee, as applicable, in making any recoverability determination respecting a P&I Advance
in respect of a Trust Subordinate Companion Loan, shall look solely to the proceeds available in respect of such Trust Subordinate
Companion Loan and shall be entitled to take into account the subordinate nature of such Trust Subordinate Companion Loan as well
as (a) to consider (among other things) (i) the obligations of the Mortgagor under the terms of the related Mortgage Loan or Companion
Loan as it may have been modified and (ii) the related Mortgaged Property in its “as-is” or then current condition
and occupancy, as modified by such party’s assumptions (consistent with the Servicing Standard in the case of the Master
Servicer or the Special Servicer or in its good faith business judgment in the case of the Trustee, solely in its capacity as Trustee)
regarding the possibility and effects of future adverse change with respect to such Mortgaged Property, (b) to estimate and consider
(consistent with the Servicing Standard in the case of the Master Servicer and the Special Servicer or in its good faith business
judgment in the case of the Trustee, solely in its capacity as Trustee) (among other things) future expenses, (c) to estimate and
consider (consistent with the applicable Servicing Standard in the case of the Master Servicer and the Special Servicer or in its
good faith business judgment in the case of the Trustee, solely in its capacity as Trustee) (among other things) the timing of
recoveries, (d) in the case of a potential P&I Advance with respect to a Trust Subordinate Companion Loan, the subordinate
nature of such Trust Subordinate Companion Loan and (e) to give due regard to the existence of any Nonrecoverable Advances which,
at the time of such consideration, the recovery of which are being deferred or delayed by the Master Servicer, in light of the
fact that related proceeds are a source of recovery not only for the Advance under consideration but also a potential source of
recovery for such delayed or deferred Advance.


 


(e)          Notwithstanding
the foregoing, (i) neither the Master Servicer nor the Trustee shall make an advance for Excess Interest, Yield Maintenance Charges,
Default Interest, late payment charges, Balloon Payment or any P&I Advance with respect to any Companion Loan (other than any
Trust Subordinate Companion Loan) and (ii) if an Appraisal Reduction Amount has been determined to exist with respect to any Mortgage
Loan (or, in the case of a


 



     -396-


     


    

 


Non-Serviced Whole Loan, an “appraisal reduction amount” (or similar item has been made
in accordance with the related Non-Serviced PSA and the Master Servicer has notice of such appraisal reduction amount) or Trust
Subordinate Companion Loan, then in the event of subsequent delinquencies thereon, the interest portion of the P&I Advance
in respect of such Mortgage Loan or Trust Subordinate Companion Loan for the related Distribution Date shall be reduced (it being
herein acknowledged that there shall be no reduction in the principal portion of such P&I Advance) to equal the product of
(x) the amount of the interest portion of such P&I Advance for such Mortgage Loan or Trust Subordinate Companion Loan for such
Distribution Date without regard to this clause 4.03(e)(ii), and (y) a fraction, expressed as a percentage, the numerator
of which is equal to the Stated Principal Balance of such Mortgage Loan or Trust Subordinate Companion Loan immediately prior to
such Distribution Date, net of the related Appraisal Reduction Amount (or, in the case of a Serviced Whole Loan, the portion of
such Appraisal Reduction Amount allocated to the related Mortgage Loan or Trust Subordinate Companion Loan), if any, and the denominator
of which is equal to the Stated Principal Balance of such Mortgage Loan or Trust Subordinate Companion Loan immediately prior to
such Distribution Date. For purposes of the immediately preceding sentence, the Periodic Payment due on the Maturity Date for a
Balloon Mortgage Loan will be the Assumed Scheduled Payment (or Y&L Towers Assumed Scheduled Payments, with respect to the
Y&L Towers Trust Subordinate Companion Loan or Standard Highline Assumed Scheduled Payments, with respect to the Standard Highline
Trust Subordinate Companion Loan) for the related Distribution Date.


 


(f)           In
no event shall either the Master Servicer or the Trustee be required to make a P&I Advance with respect to any Companion Loan
other than any Trust Subordinate Companion Loan.


 


Section
4.04     Allocation of Realized Losses. (a) On each Distribution Date, immediately following
the distributions to be made on such date pursuant to Section 4.01, the Certificate Administrator shall calculate the
amount, if any, by which (W) with respect to the Mortgage Loans (i) the aggregate Stated Principal Balance (for purposes of
this definition only, not giving effect to any reductions of the Stated Principal Balance for payments of principal collected
on the Mortgage Loans that were used to reimburse any Workout-Delayed Reimbursement Amounts pursuant to Section
3.05(a)(v) to the extent such Workout-Delayed Reimbursement Amounts are not otherwise determined to be Nonrecoverable
Advances) of the Mortgage Loans and any REO Loans (excluding any portion allocable to any related Companion Loan other than
the Y&L Towers Trust Subordinate Companion Loan or the Standard Highline Trust Subordinate Companion Loan, if applicable)
expected to be outstanding immediately following such Distribution Date, is less than (ii) the then-aggregate Certificate
Balance of the Pooled Regular Interests after giving effect to distributions of principal on such Distribution Date (any such
deficit, the “Pooled Realized Loss”), (X) with respect to the Y&L Towers Trust Subordinate
Companion Loan (i) the Stated Principal Balance of the Y&L Towers Trust Subordinate Companion Loan (including the assumed
Stated Principal Balance if the Y&L Towers Trust Subordinate Companion Loan have become an REO Loan) expected to be
outstanding immediately following such Distribution Date is less than (ii) the aggregate Certificate Balance of the Y&L
Towers Loan-Specific Certificates after giving effect to distributions of principal on such Distribution Date (any such
deficit with respect to the Y&L Towers Loan-Specific Certificates, the “Y&L Towers Realized Loss”)
and (Y) with respect to the Standard Highline Trust Subordinate Companion Loan (i) the Stated Principal Balance of the


 



     -397-


     


    

 


Standard Highline Trust Subordinate Companion Loan (including the assumed Stated Principal Balance if the Standard Highline
Trust Subordinate Companion Loan have become an REO Loan) expected to be outstanding immediately following such Distribution
Date is less than (ii) the aggregate Certificate Balance of the Standard Highline Loan-Specific Certificates after giving
effect to distributions of principal on such Distribution Date (any such deficit with respect to the Standard Highline
Loan-Specific Certificates, the “Standard Highline Realized Loss”). Realized Losses with respect to the
Yorkshire & Lexington Towers Whole Loan shall be allocated first to the Y&L Towers Trust Subordinate Companion
Loan (and, correspondingly, to the Class UES-A, Class UES-B, Class UES-C and Class UES-D Regular Interests, as applicable, in
reverse alphabetic order) and then to the Yorkshire & Lexington Towers Pari Passu Companion Loan and to the Yorkshire
& Lexington Towers Mortgage Loan on a pro rata and pari passu basis. Realized Losses with respect to The
Standard Highline NYC Whole Loan shall be allocated first to the Standard Highline Non-Trust Junior
Subordinate Companion Loan, then to the Standard Highline Non-Trust Senior Subordinate Companion Loan, then to the Standard
Highline Trust Subordinate Companion Loan (and, correspondingly, to the Class STN-A, Class STN-B and Class STN-C Regular
Interests, as applicable, in reverse alphabetic order) and then to The Standard Highline NYC Mortgage Loan. Any allocation of
Realized Losses to a Class of Regular Interests shall be made by reducing the Certificate Balance thereof by the amount so
allocated. The allocation of Realized Losses shall constitute an allocation of losses and other shortfalls experienced by the
Trust. Reimbursement of previously allocated Realized Losses will not constitute distributions of principal for any purpose
and will not result in an additional reduction in the Certificate Balance of the applicable Regular Interest in respect of
which any such reimbursement is made. With respect to any Regular Interest (other than any Class X Regular Interest), to the
extent any Nonrecoverable Advances (plus interest thereon) that were reimbursed from principal collections on the Mortgage
Loans, the Y&L Towers Trust Subordinate Companion Loan and/or the Standard Highline Trust Subordinate Companion Loan and
previously resulted in a reduction of the Principal Distribution Amount, the Y&L Towers Principal Distribution Amount or
the Standard Highline Principal Distribution Amount, as applicable, are subsequently recovered on the related Mortgage Loan
and/or Trust Subordinate Companion Loan, the amount of such recovery will be added to the Certificate Balance of the Class or
Classes of Regular Interest that previously were allocated Realized Losses and in the case of Realized Losses, in sequential
order according to the priority of payments for the Regular Interests (other than the Class X Regular Interests) (and in the
case of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5 and Class A-SB Regular Interests, on a pro rata
basis according to the amount of unreimbursed Realized Losses on such Classes), in each case up to the amount of the
unreimbursed Realized Losses allocated to such Class of Regular Interest (other than the Loan-Specific Regular
Interests).


 


(b)          (i)
On each Distribution Date, the Certificate Balances of each Pooled Regular Interest (other than the Class X Regular Interests)
will be reduced without distribution, as a write-off to the extent of any Pooled Realized Losses, if any, allocable to such Certificates
with respect to such Distribution Date. Any such write-off shall be allocated first, to the Class NR Regular Interest, second,
to the Class F Regular Interest, third, to the Class E Regular Interest, fourth, to the Class D Regular Interest,
fifth, to the Class C Regular Interest, sixth, to the Class B Regular Interest, seventh, to the Class A-S
Regular Interest, and then, pro rata (based on their respective Certificate Balances), Class A-1, Class A-2, Class
A-3, Class A-4, Class A-5 and Class A-SB Regular Interests, in each case until the remaining Certificate Balances of such


 



     -398-


     


    

 


Regular
Interests have been reduced to zero. On each Distribution Date, the Certificate Balances of the Y&L Towers Loan-Specific Regular
Interests will be reduced without distribution as a write-off to the extent of any Y&L Towers Realized Losses attributable
to the Y&L Towers Trust Subordinate Companion Loan in accordance with Section 4.04(a). Any such write-off with respect
to the Y&L Towers Trust Subordinate Companion Loan shall be allocated first, to the Class UES-D Regular Interest, then,
to the Class UES-C Regular Interest, then, to the Class UES-B Regular Interest, then, to the Class UES-A Regular
Interest, in each case until the remaining Certificate Balances of such Regular Interests have been reduced to zero. On each Distribution
Date, the Certificate Balances of the Standard Highline Loan-Specific Regular Interests will be reduced without distribution as
a write-off to the extent of any the Standard Highline Realized Losses attributable to the Standard Highline Trust Subordinate
Companion Loan in accordance with Section 4.04(a). Any such write-off with respect to the Standard Highline Trust Subordinate
Companion Loan shall be allocated first, to the Class STN-C Regular Interest, then, to the Class STN-B Regular Interest,
then, to the Class STN-A Regular Interest, in each case until the remaining Certificate Balances of such Regular Interests
have been reduced to zero.

As of the first Determination
Date following a Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Trust Subordinate Companion Loan becoming an AB Modified
Loan, the Special Servicer shall calculate whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan,
taking into account the most recent Appraisal obtained by the Special Servicer with respect to such Mortgage Loan or Trust Subordinate
Companion Loan, and all other information relevant to a Collateral Deficiency Amount determination. Upon obtaining knowledge or
receiving notice by the Master Servicer that a Non-Serviced Mortgage Loan has become an AB Modified Loan, the Master Servicer shall
(i) promptly request from the related Non-Serviced Master Servicer, Non-Serviced Special Servicer and Non-Serviced Trustee the
most recent appraisal with respect to such AB Modified Loan, in addition to all other information reasonably required by the Master
Servicer to calculate whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan, and (ii) as of the first
Determination Date following receipt by the Master Servicer of the appraisal and any other information set forth in the immediately
preceding clause (i) that the Master Servicer reasonably expects to receive, calculate whether a Collateral Deficiency Amount
exists with respect to such AB Modified Loan, taking into account the most recent appraisal obtained by the Non-Serviced Special
Servicer with respect to such Non-Serviced Mortgage Loan, and all other information relevant to a Collateral Deficiency Amount
determination. Upon obtaining knowledge or receipt of notice by any other party to this Agreement that a Non-Serviced Mortgage

For purposes of determining
the Controlling Class and whether a Control Termination Event has occurred and is continuing, Collateral Deficiency Amounts allocated
to a related Mortgage Loan that is an AB Modified Loan will be allocated to each Class of Control Eligible Corresponding Certificates
in reverse sequential order to notionally reduce the related Certificate Balances until the Certificate Balance of each such Class
of Control Eligible


 



     -403-


     


    

 


Corresponding Certificates is reduced to zero (i.e., first, to the Class NR Certificates, second,
to the Class F Certificates, and third, to the Class E Certificates). For the avoidance of doubt, for purposes of determining
the Controlling Class or the occurrence and continuance of a Control Termination Event, any Class of Control Eligible Corresponding
Certificates shall be allocated both applicable Appraisal Reduction Amounts and applicable Collateral Deficiency Amounts (the sum
of which shall constitute the applicable Cumulative Appraisal Reduction Amount), in accordance with this Section 4.05(a).


 


With respect to (i) any
Appraisal Reduction Amount calculated for the purposes of determining the Non-Reduced Certificates or determining the Voting Rights
of the related Classes for purposes of removal of the Special Servicer or Operating Advisor and (ii) any Appraisal Reduction Amount
or Collateral Deficiency Amount calculated for purposes of determining the Controlling Class or the occurrence and continuance
of a Control Termination Event, the appraised value of the related Mortgaged Property shall be determined on an “as is”
basis.

Towers Mortgage Loan and the Yorkshire & Lexington Towers Pari Passu Companion Loan on a pro rata basis. Appraisal Reduction
Amounts allocated to the Y&L Towers Trust Subordinate Companion Loan will be allocated to each Class of Y&L Towers Loan-Specific
Certificates in reverse sequential order to notionally reduce the related Certificate Balances until the related Certificate Balance
of each such Class is reduced to zero (i.e., first, to the Class UES-D Regular Interest, then, to the Class UES-C
Regular Interest, then, to the Class UES-B Regular Interest, and then, to the Class UES-A Regular Interest).

In addition, for purposes
of determining the Y&L Towers Controlling Class and the occurrence of a Y&L Towers Trust Subordinate Control Termination
Event, Collateral Deficiency Amounts allocated to the Y&L Towers Trust Subordinate Companion Loan will be allocated to each
Class of Y&L Towers Loan-Specific Certificates in reverse sequential order to notionally reduce the Certificate Balance thereof
until the related Certificate Balance of each such Class is reduced to zero (i.e., first, to the Class UES-D Certificates,
then, to the Class UES-C Certificates, then, to the Class UES-B Certificates, and then, to the Class UES-A
Certificates). For the avoidance of doubt, for purposes of determining the Y&L Towers Controlling Class and the occurrence
of a Y&L Towers Trust Subordinate Companion Loan Control Termination Event, any Class of Y&L Towers Loan-Specific Certificates
will be allocated both applicable Appraisal Reduction Amounts and applicable Collateral Deficiency Amounts, as described in this
paragraph.


 


For purposes of determining
the Non-Reduced Loan-Specific Regular Interests, the Standard Highline Controlling Class and the occurrence of a Standard Highline
Non-Trust Junior Subordinate Control Termination Event, a Standard Highline Non-Trust Senior Subordinate Control Termination Event

Loan and then to The Standard Highline NYC Mortgage Loan. Appraisal Reduction Amounts allocated to the Standard Highline
Trust Subordinate Companion Loan will be allocated to each Class of Standard Highline Loan-Specific Certificates in reverse sequential

to zero (i.e., first, to the Class STN-C Regular Interest, then, to the Class STN-B Regular Interest, and then,
to the Class STN-A Regular Interest).


 


Any such allocations
of Appraisal Reduction Amounts to:


 


(i)             the

Reduction Amounts and applicable Collateral Deficiency Amounts, as described in this paragraph.


 


The Special Servicer
(in the case of a Mortgage Loan other than a Non-Serviced Mortgage Loan) or the Master Servicer (in the case of a Non-Serviced
Mortgage Loan) shall promptly notify the Special Servicer or the Master Servicer, as applicable, and the Master Servicer shall
notify the Certificate Administrator of the amount of any Appraisal Reduction Amount (which notification to the Certificate Administrator
shall be made by delivery of such information included in the CREFC® Loan Periodic Update File in accordance with Section
3.12(d)), any Collateral Deficiency Amount and any resulting Cumulative Appraisal Reduction Amount allocated to each Mortgage
Loan, AB Modified Loan or Serviced Whole Loan (which notification may be satisfied through delivery of such information included
in the CREFC® Appraisal Reduction Amount Template included in the CREFC® Investor Reporting Package in accordance with
Section 3.12(d) or such other report or reports mutually agreed upon between the Master Servicer and the Certificate Administrator)
and the Certificate Administrator shall promptly post notice of such Appraisal Reduction Amount, Collateral Deficiency Amount and/or
Cumulative Appraisal Reduction Amount, as applicable, to the Certificate Administrator’s Website. Based on information in
its possession, the Certificate Administrator shall determine from time to time which Class of Certificates is the Controlling
Class. Promptly upon its determination of a change in the Controlling Class, the Certificate Administrator shall notify the Master
Servicer, the Special Servicer and the Operating Advisor of such event, including the identity and contact information of the new
Controlling Class Certificateholder and the identity of the Controlling Class as set forth in Section 3.23(m) (the cost
of obtaining such information from the Depository being an expense of the Trust).


 


(b)         (i)
The Holders of the majority of Voting Rights of any Class of Control Eligible Corresponding Certificates or Loan-Specific Certificates
respectively, that is determined at any time of determination to no longer be the Controlling Class, the Y&L Towers Controlling
Class or the Standard Highline Controlling Class (any such Class, an “Appraised-Out Class”) as a result of an
Appraisal Reduction Amount or Collateral Deficiency Amount (as applicable) in respect of such Class shall have the right, at their
sole expense, to require the Special Servicer to order (or, with respect to a Collateral Deficiency Amount calculation for a Non-Serviced
Mortgage Loan, require the Master Servicer to request from the applicable Non-Serviced Special Servicer) a second Appraisal with
respect to any Mortgage Loan (or Serviced Whole Loan) for


 



     -406-


     


    

 


which an Appraisal Reduction Event has occurred or as to which there
exists a Collateral Deficiency Amount (such Holders, the “Requesting Holders”). With respect to any such Mortgage
Loan (other than with respect to a Non-Serviced Mortgage Loan), the Special Servicer shall use its reasonable efforts to cause
such second Appraisal to be (i) delivered within thirty (30) days from receipt of the Requesting Holders’ written request
and (ii) prepared on an “as-is” basis by an MAI appraiser (provided that such MAI appraiser may not be the same
MAI appraiser that provided the Appraisal in respect of which the Requesting Holders are requesting the Special Servicer to obtain
an additional Appraisal). With respect to any such Non-Serviced Mortgage Loan, the Master Servicer shall use commercially reasonable
efforts to obtain such second appraisal from the applicable Non-Serviced Special Servicer.


 


(ii)       Upon
receipt of any supplemental Appraisal pursuant to clause (i) above, the Master Servicer (for Collateral Deficiency Amounts on Non-Serviced
Mortgage Loans), the applicable Non-Serviced Special Servicer (for Appraisal Reduction Amounts on Non-Serviced Mortgage Loans to
the extent provided for in the applicable Non-Serviced PSA and applicable Intercreditor Agreement) and the Special Servicer (for
Mortgage Loans other than Non-Serviced Mortgage Loans) shall determine, in accordance with the Servicing Standard, whether, based
on its assessment of such supplemental Appraisal, any recalculation of the Appraisal Reduction Amount or Collateral Deficiency
Amount (as applicable) is warranted, and if so warranted, the Special Servicer shall recalculate the Appraisal Reduction Amount
or Collateral Deficiency Amount, as applicable, based on such supplemental appraisal. If required by such recalculation, the Appraised-Out
Class shall be reinstated as the Controlling Class, the Y&L Towers Controlling Class or the Standard Highline Controlling Class,
as applicable, and each other Appraised-Out Class shall, if applicable, have its related Certificate Balance notionally restored
to the extent required by such recalculation of the Appraisal Reduction Amount or Collateral Deficiency Amount, if applicable.
In addition, the Requesting Holders of any Appraised-Out Class shall have the right, at their sole expense, to require the Special
Servicer to order an additional appraisal of any Mortgage Loan for which an Appraisal Reduction Event has occurred or as to which
there exists a Collateral Deficiency Amount, and the Special Servicer shall use its reasonable efforts to obtain such appraisal
from an MAI appraiser reasonably acceptable to the Special Servicer within thirty (30) days from receipt of the Requesting Holders’
written request; provided, that the Special Servicer shall not be required to obtain such appraisal if it determines in
accordance with the Servicing Standard that no events at or with regard to the related Mortgaged Property or Mortgaged Properties
have occurred that would have a material effect on the appraised value of the related Mortgaged Property or Mortgaged Properties.
The Holders of an Appraised-Out Class requesting any supplemental Appraisal pursuant to clause (i) above shall refrain from
exercising any direction, control, consent and/or similar rights of the Controlling Class, the Y&L Towers Controlling Class
or the Standard Highline Controlling Class, as applicable, until such time, if any, as the Class is reinstated as the Controlling
Class, the Y&L Towers Controlling Class or the Standard Highline Controlling Class as applicable (such period beginning upon
receipt by the Special Servicer of any request to obtain a supplemental Appraisal pursuant to clause (i) above to but excluding
the date on which either (A) the Special Servicer determines that no recalculation of the Appraisal Reduction Amount or Collateral
Deficiency Amount (as applicable) is warranted or (B) the Special Servicer recalculates the Appraisal Reduction


 



     -407-


     


    

 


Amount or Collateral
Deficiency Amount (as applicable) based on the supplemental Appraisal, the “Appraisal Review Period”). The rights
of the Controlling Class, the Y&L Towers Controlling Class or the Standard Highline Controlling Class during each Appraisal
Review Period shall be exercised by the most senior Class of Control Eligible Corresponding Certificates, if any, Y&L Towers
Loan-Specific Certificates or Standard Highline Loan-Specific Certificates, if any, respectively.


 


(c)         With
respect to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any Serviced Whole Loan as to which an Appraisal Reduction
Event has occurred (unless such Mortgage Loan or Serviced Whole Loan has remained current for three consecutive Periodic Payments,
and with respect to which no other Appraisal Reduction Event has occurred with respect to that Mortgage Loan during the preceding
three months (for such purposes taking into account any amendment or modification of such Mortgage Loan, any related Companion
Loan or Serviced Whole Loan)), the Special Servicer shall (1) within thirty (30) days of the occurrence or of each anniversary
of the related Appraisal Reduction Event, and (2) upon its determination that the value of the related Mortgaged Property has materially
changed, notify the Master Servicer of the occurrence of such anniversary or determination and order an Appraisal (which may be
an update of a prior Appraisal), the cost of which shall be paid by the Master Servicer as a Servicing Advance or to the extent
it would be a Nonrecoverable Advance, an expense of the Trust, or conduct an internal valuation, as applicable, and promptly following
receipt of any such Appraisal or performance of such valuation (or receipt of any Appraisal obtained in accordance with Section
4.05(b) above), shall promptly deliver a copy thereof to the Master Servicer, the Certificate Administrator, the Trustee, the
Operating Advisor and ((i) prior to the occurrence and continuance of any Consultation Termination Event and (ii) other than with
respect to any Mortgage Loan that is an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing
Certificateholder, the Holder of the majority of the Controlling Class) the Directing Holder. Based upon such Appraisal or internal
valuation (or any Appraisal obtained in accordance with Section 4.05(b) above) and receipt of information reasonably requested
by the Special Servicer from the Master Servicer necessary to calculate the Appraisal Reduction Amount that is either in the Master
Servicer’s possession or reasonably obtainable by the Master Servicer, the Special Servicer shall determine or redetermine,
as applicable, and report to the Master Servicer, the Certificate Administrator, the Trustee, the Operating Advisor and ((i) prior
to the occurrence and continuance of any Consultation Termination Event and (ii) other than with respect to any Mortgage Loan that
is an Excluded Loan as to such party) the Directing Holder, the amount and calculation or recalculation of the Appraisal Reduction
Amount or Collateral Deficiency Amount with respect to such Mortgage Loan, Companion Loan or Serviced Whole Loan, as applicable,
and such report shall be delivered in the CREFC® Appraisal Reduction Amount Template format; provided, however,
that the Special Servicer shall not be liable for failure to comply with such duties insofar as such failure results from a failure
of the Master Servicer to provide sufficient information to the Special Servicer to comply with such duties or failure by the Master
Servicer to otherwise comply with its obligations hereunder. Such report shall also be forwarded by the Master Servicer (or the
Special Servicer if the related Mortgage Loan is a Specially Serviced Loan), to the extent the related Serviced Companion Loan
has been included in an Other Securitization, to the Other Servicer, to the extent required by the related Intercreditor Agreement,
of such Other Securitization into which the related Serviced Companion Loan has been sold, or to the holder of any related Serviced
Companion Loan by the Master Servicer (or the Special Servicer if the


 



     -408-


     


    

 


 related Mortgage Loan is a Specially Serviced Loan). If the
Special Servicer is required to redetermine the Appraisal Reduction Amount or Collateral Deficiency Amount, such redetermined Appraisal
Reduction Amount or Collateral Deficiency Amount shall replace the prior Appraisal Reduction Amount or Collateral Deficiency Amount,
as applicable, with respect to such Mortgage Loan, Companion Loan or Serviced Whole Loan, as applicable. Prior to the occurrence
and continuance of a Consultation Termination Event (and unless the related Mortgage Loan is an Excluded Loan as to such party),
the Special Servicer shall consult with the Directing Holder with respect to any Appraisal, valuation or downward adjustment in
connection with an Appraisal Reduction Amount or Collateral Deficiency Amount. Notwithstanding the foregoing but subject to Section
4.05(b), the Special Servicer shall not be required to obtain an Appraisal or conduct an internal valuation, as applicable,
with respect to a Mortgage Loan or related Companion Loan or Serviced Whole Loan as to which an Appraisal Reduction Event has occurred
to the extent the Special Servicer has obtained an Appraisal or conducted such a valuation (in accordance with requirements of
this Agreement), as applicable, with respect to the related Mortgaged Property within the six-month period immediately prior to
the occurrence of such Appraisal Reduction Event. Instead, the Special Servicer may use such prior Appraisal or valuation, as applicable,
in calculating any Appraisal Reduction Amount with respect to such Mortgage Loan or related Companion Loan or Serviced Whole Loan;
provided that the Special Servicer is not aware of any material change to the related Mortgaged Property having occurred
and affecting the validity of such Appraisal or valuation.


 


The Master Servicer shall
deliver by electronic mail to the Special Servicer any information in its possession reasonably required to determine, calculate,
redetermine or recalculate any Appraisal Reduction Amount, using reasonable efforts to deliver such information, within four (4)
Business Days following the Special Servicer’s reasonable request therefor (which request must be made promptly after the
Special Servicer’s receipt of the applicable appraisal or preparation of the applicable internal evaluation); provided
that the Special Servicer’s failure to timely make such request shall not relieve the Master Servicer of its obligation to
use reasonable efforts to provide such information to the Special Servicer within four (4) Business Days following the Special
Servicer’s reasonable request.


 


(d)         Any
Mortgage Loan (other than any Non-Serviced Mortgage Loan), any related Serviced Companion Loan and any Serviced Whole Loan previously
subject to an Appraisal Reduction Amount, which has become a Corrected Loan (for such purposes taking into account any amendment
or modification of such Mortgage Loan, any related Serviced Companion Loan and any Serviced Whole Loan), and with respect to which
no other Appraisal Reduction Event has occurred and is continuing, will no longer be subject to an Appraisal Reduction Amount.
Any Appraisal Reduction Amount in respect of a Non-Serviced Whole Loan shall be calculated by the applicable party under and in
accordance with and pursuant to the terms of the applicable Non-Serviced PSA.


 


(e)          Each
Serviced Whole Loan will be treated as a single Mortgage Loan for purposes of calculating an Appraisal Reduction Amount with respect
to the Mortgage Loan and Companion Loan(s) that comprise such Serviced Whole Loan. Any Appraisal Reduction Amount in respect of
a Serviced AB Whole Loan will be allocated in accordance with the related Intercreditor Agreement or, if no allocation is specified
in the related Intercreditor Agreement, then, first, to the related AB Subordinate Companion Loan (or with respect to The Standard


 



     -409-


     


    

 


Highline NYC Whole Loan, first, to the Standard Highline Non-Trust Junior Subordinate Companion Loan, then, to the Standard
Highline Non-Trust Senior Subordinate Companion Loan and then, to the Standard Highline Trust Subordinate Companion Loan) (until
its principal balance is notionally reduced to zero by such Appraisal Reduction Amounts) and then, pro rata, to the related
AB Mortgage Loan and any related Pari Passu Companion Loan(s). Any Appraisal Reduction Amount in respect of any Serviced Pari Passu
Whole Loan will be allocated in accordance with the related Intercreditor Agreement or, if no allocation is specified in the related
Intercreditor Agreement, then, pro rata, between the related Serviced Pari Passu Mortgage Loan and the related Serviced
Pari Passu Companion Loan(s), based upon their respective outstanding principal balances.


 


Section
4.06     Grantor Trust Reporting. (a) The parties intend that the portion of the Trust Fund
constituting the Grantor Trust shall constitute, and that the affairs of the Grantor Trust shall be conducted so as to
qualify such portion as, a “grantor trust” under subpart E, part I of subchapter J of the Code, and the
provisions hereof shall be interpreted consistently with this intention. In furtherance of such intention, neither the
Trustee nor the Certificate Administrator shall have the power to vary the investment of the Certificateholders in the
Grantor Trust so as to improve their rate of return. The Certificate Administrator shall prepare or cause to be prepared,
submit to the Trustee for execution (and the Trustee shall timely execute and timely return to the Certificate Administrator)
and timely file all Tax Returns in respect of the Grantor Trust. In addition, the Certificate Administrator shall (A) file,
or cause to be filed, Internal Revenue Service Form 1041, Form 1099 or such other form as may be applicable with the Internal
Revenue Service with copies of the statements in the following clause and (B) furnish, or cause to be furnished, to
the Certificateholders, their allocable share of income and expense with respect to the related Specific Grantor Trust Assets
in the time or times and in the manner required by the Code.


 


(b)       The
Grantor Trust will be treated as a WHFIT that is a WHMT. The Certificate Administrator will report as required under the WHFIT
Regulations to the extent such information as is reasonably necessary to enable the Certificate Administrator to do so is provided
to the Certificate Administrator on a timely basis. The Certificate Administrator is hereby directed to assume that DTC is the
only “middleman” as defined by the WHFIT Regulations unless the Depositor provides the Certificate Administrator with
the identities of other “middlemen” that are Certificateholders. The Certificate Administrator shall be entitled to
rely on the first sentence of this Section 4.06(b) and shall be entitled to indemnification in accordance with the terms
of this Agreement in the event that the Internal Revenue Service makes a determination that the first sentence of this paragraph
is incorrect.


 


(c)            The
Certificate Administrator shall report required WHFIT information using the accrual method, except to the extent the WHFIT Regulations
specifically require a different method. The Certificate Administrator shall be under no obligation to determine whether any Certificateholder
uses the cash or accrual method. The Certificate Administrator shall make available (via its website) WHFIT information to Certificateholders
annually. In addition, the Certificate Administrator shall not be responsible or liable for providing subsequently amended, revised
or updated information to any Certificateholder, unless requested by the Certificateholder.


 






     -410-


     


    




 


(d)            The
Certificate Administrator shall not be liable for failure to meet the reporting requirements of the WHFIT Regulations nor for any
penalties thereunder if such failure is due to: (i) the lack of reasonably necessary information being provided to the Certificate
Administrator or (ii) incomplete, inaccurate or untimely information being provided to the Certificate Administrator. Each Certificateholder,
by acceptance of its interest in such class of securities, will be deemed to have agreed to provide the Certificate Administrator
with information regarding any sale of such securities, including the price, amount of proceeds and date of sale. Absent receipt
of information regarding any sale of a Certificate, including the price, amount of proceeds and date of sale from the beneficial
owner thereof or the Depositor, the Certificate Administrator shall assume there is no secondary market trading of WHFIT interests.


 


(e)       To
the extent required by the WHFIT Regulations, the Certificate Administrator shall use reasonable efforts to publish on an appropriate
website the CUSIP for the Class Z Certificates. The CUSIP so published will represent the Rule 144A CUSIP. The Certificate Administrator
shall make reasonable good faith efforts to keep the website accurate and updated to the extent such CUSIP has been received. Absent
the receipt of such CUSIP, the Certificate Administrator will use a reasonable identifier number in lieu of a CUSIP. The Certificate
Administrator shall not be liable for investor reporting delays that result from the receipt of inaccurate or untimely CUSIP information.


 


Section
4.07     Investor Q&A Forum; Investor Registry; and Rating Agency Q&A Forum and Document Request Tool. (a) The
Certificate Administrator shall make available, only to Privileged Persons, the Investor Q&A Forum. The
“Investor Q&A Forum” shall be a service available on the Certificate Administrator’s Website,
where (i) Certificateholders and beneficial owners of Certificates that are Privileged Persons may submit questions to (A)
the Certificate Administrator relating to the Distribution Date Statement, (B) the Master Servicer or the Special Servicer,
as the case may be, relating to the reports being made available pursuant to Section 3.13(b), the Mortgage Loans
(excluding any Non-Serviced Mortgage Loan), the Trust Subordinate Companion Loans or the related Mortgaged Properties or (C)
the Operating Advisor relating to the Operating Advisor Annual Report or other reports prepared by the Operating Advisor or
actions by the Special Servicer referenced in any Operating Advisor Annual Report (each an “Inquiry” and
collectively, “Inquiries”), and (ii) Privileged Persons may view Inquiries that have been previously

receipt of such answer, as the case may be) such Inquiry and the related answer to the Certificate Administrator’s

response would require the Operating Advisor to provide information to such inquiring Certificateholders that they are
otherwise not entitled to receive under the terms of this Agreement.


 


(b)            The
Certificate Administrator shall make available to any Certificateholder and any Certificate Owner that is a Privileged Person,
the Investor Registry. The “Investor Registry” shall be a voluntary service available on the Certificate Administrator’s
Website, where Certificateholders and Certificate Owners that are Privileged Persons can register and thereafter obtain information

Registry shall certify that (a) it is a Certificateholder or a Certificate Owner and a Privileged Person and (b) it grants authorization
to the Certificate Administrator to make its name and contact information available on the Investor Registry for at least forty-five
(45) days from the date of such certification to persons entitled to access to the Investor Registry. Such Person shall then be
asked to enter certain mandatory fields such as the individual’s name, the company name and email address, as well as certain
optional fields such as address, phone, and Class(es) of Certificates owned. If any Certificateholder or Certificate Owner notifies

Statements, or submit questions to the Master Servicer or the Special Servicer, as the case may be, relating to the reports prepared
by such parties (each such submission, a “Rating Agency Inquiry”), and (ii) view Rating Agency Inquiries that
have been previously submitted and answered, together with the responses thereto. In addition, NRSROs may use the forum to submit
requests (each such submission also, a “Rating Agency Inquiry”) to the Master Servicer for loan-level reports
and other related information. Upon receipt of a Rating Agency Inquiry for the Master Servicer or the Special Servicer, the 17g-5
Information Provider shall forward the Rating Agency Inquiry to the appropriate person (in the case of the Master Servicer to the

privilege with, or the disclosure of attorney work product, or (iii) (A) answering any Rating Agency Inquiry would materially increase

Special Servicer, as applicable, and (B) the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable,
determines in accordance with the Servicing Standard (or in good faith, in the case of the Certificate Administrator) that the
performance of such duties or the payment of such costs and expenses is beyond the scope of its duties in its capacity as Certificate
Administrator, Master Servicer or the Special Servicer, as applicable, under this Agreement, it shall not be required to answer
such Rating Agency Inquiry and shall promptly notify the 17g-5 Information Provider by email of such determination. The 17g-5 Information
Provider shall promptly thereafter post the Rating Agency Inquiry with the reason it was not answered to the Rating Agency Q&A

Depositor shall upon the receipt of each Mortgage Loan Seller’s Diligence File Certificate, deliver to the Certificate Administrator

the contents of each Diligence File actually received by it to the Secure Data Room. Access to the Secure Data Room shall be granted
by the Certificate Administrator to (i) the Asset Representations Reviewer and (ii) provided that the Certificate Administrator
has received the Diligence File Certificate from each Mortgage Loan Seller pursuant to Section 2.01(h), any other Person
at the direction of the Depositor, in each case, upon the occurrence of an Affirmative Asset Review Vote and receipt by the Certificate
Administrator of a certification substantially in the form of Exhibit RR hereto (which shall be sent via email to trustadministrationgroup@wellsfargo.com

     -414-


     


    

 


no obligation
to post any documents or information to the Secure Data Room other than the contents of the Diligence Files initially delivered
to it by the Depositor.


 


(b)            The
Certificate Administrator shall not have any obligation or duty to verify, review, confirm or otherwise determine whether the type,
number or contents of any Diligence File delivered to the Certificate Administrator is accurate, complete, or relates to the transaction
or confirm that all documents and information constituting any Diligence File have actually been delivered to the Certificate Administrator.
In no case shall the Certificate Administrator be deemed to have obtained actual or constructive knowledge of the contents of,
or information contained in, any Diligence File by virtue of posting such Diligence File to the Secure Data Room. In the event
that any document or information is posted in error, the Certificate Administrator may remove such document or information from
the Secure Data Room. The Certificate Administrator shall not have any obligation to produce physical or electronic copies of any
document or information provided to it for posting to the Secure Data Room. The Certificate Administrator shall not be responsible
or held liable for any other Person’s use or dissemination of the documents or information contained on the Secure Data Room;
provided that such event or occurrence is not also a result of its own negligence, bad faith or willful misconduct. The
Certificate Administrator shall not be required to restrict access to the Secure Data Room on a loan-by-loan basis and any Person
with access to the Secure Data Room shall covenant to access only the information necessary to perform its duties and responsibilities
under this Agreement.


 


(c)            Upon
the resignation or removal of the Certificate Administrator pursuant to Section 8.07, the Certificate Administrator shall
transfer electronic copies of the Diligence Files to a successor certificate administrator designated in writing by the Depositor
or the Master Servicer, and all costs and expenses associated with the transfer of the Diligence Files shall be payable as part
of the costs and expenses associated with the transfer of its responsibilities upon the resignation or removal of the Certificate
Administrator pursuant to Section 8.07. Following the date on which any Mortgage Loan is paid in full, liquidated, repurchased
or otherwise removed from the Trust, the Master Servicer or the Special Servicer, as applicable, may direct the Certificate Administrator
in writing to delete the Diligence File related to such Mortgage Loan from the Secure Data Room; provided that absent such
direction, the Certificate Administrator shall not be obligated to delete any Diligence File from the Secure Data Room. Following
the termination of the Trust pursuant to Section 9.01, the Certificate Administrator shall be permitted to delete all files
from the Secure Data Room. Upon deletion, in no event shall the Certificate Administrator be obligated to reproduce or retrieve
such deleted files.

THE CERTIFICATES


 


Section
5.01     The Certificates. (a) The Certificates will be substantially in the respective forms annexed hereto as Exhibits
A-1 through and including A-25, with such appropriate insertions, omissions, substitutions and other variations as
are required or permitted by this Agreement or as may, in the reasonable judgment of the Certificate Registrar, be


 






     -415-


     


    

 


necessary,
appropriate or convenient to comply, or facilitate compliance, with applicable laws, and may have such letters, numbers or
other marks of identification and such legends or endorsements placed thereon as may be required by law, or as may,
consistently herewith, be determined by the officers executing such Certificates, as evidenced by their execution thereof.
The Class X Certificates will be issuable only in minimum Denominations of authorized initial Notional Amount of not less
than $1,000,000 and in integral multiples of $1.00 in excess thereof. The Offered Certificates (other than the Class X-A
Certificates and Class X-B Certificates) and the Loan-Specific Certificates (other than the Class UES-X Certificates and
Class STN-X Certificates) will be issuable only in minimum Denominations of authorized initial Certificate Balance of not
less than $10,000, and in integral multiples of $1.00 in excess thereof. The Non-Registered Certificates (other than the
Class X-E, Class V, Class Z and Class R Certificates) will be issuable in minimum Denominations of authorized initial
Certificate Balance of not less than $100,000, and in integral multiples of $1.00 in excess thereof. If the Original
Certificate Balance or initial Notional Amount, as applicable, of any Class does not equal an integral multiple of $1.00,
then a single additional Certificate of such Class may be issued in a minimum denomination of authorized initial Certificate
Balance or initial Notional Amount, as applicable, that includes the excess of (i) the Original Certificate Balance or
initial Notional Amount, as applicable, of such Class over (ii) the largest integral multiple of $1.00 that does not
exceed such amount. The Certificates of each Class of Class V Certificates will be issuable in one or more Definitive
Certificates, in minimum denominations of authorized Certificate Balance as described in the succeeding table, and multiples

percentage interests of 1% of such Class Z Certificates.


 


(b)           One
authorized signatory shall sign the Certificates for the Certificate Registrar by manual or facsimile signature. If an authorized
signatory whose signature is on a Certificate no longer holds that office at the time the Certificate Registrar countersigns the
Certificate, the Certificate shall be valid nevertheless. A Certificate shall not be valid until an authorized signatory of the
Certificate Registrar (who may be the same officer who executed the Certificate) manually countersigns the Certificate. The signature
shall be conclusive evidence that the Certificate has been executed and countersigned under this Agreement.


 


(c)            During
the Transfer Restriction Period, the HRR Certificates shall only be held as Definitive Certificates in the Third Party Purchaser
Safekeeping Account by the Certificate Administrator (and the Holder of the HRR Certificates shall be registered on the Certificate
Register), unless otherwise consented to by the Retaining Sponsor. The Certificate Administrator acknowledges that the HRR Certificates
have been pledged by the Third Party Purchaser to the Retaining Sponsor to secure certain obligations of the Third Party Purchaser
pursuant to Section 5 of the Credit Risk Retention Compliance Agreement and are subject to the security interest created thereunder.
The Certificate Administrator (in the capacity described in this Section, the “Retained Interest Custodian”)
hereby agrees to acquire and hold possession of the HRR Certificates on behalf of the Retaining Sponsor, and hereby expressly acknowledges
that it holds such Certificates for and on behalf of the Retaining Sponsor. The Retained Interest Custodian hereby agrees that
it shall not relinquish possession of the HRR Certificates to any Person except as directed in writing by the Retaining Sponsor.
Upon receipt by the Retained


 



     -416-


     


    

 


Interest Custodian of a written notice from the Retaining Sponsor (which notice shall also be provided
to the Third-Party Purchaser) directing the further delivery of the HRR Certificates from the Retaining Sponsor (including any
direction to reregister the HRR Certificates in the name of another Person), the Retained Interest Custodian shall, no sooner than
two (2) Business Days of receipt thereof, promptly comply with such instructions of the Retaining Sponsor notwithstanding any direction
to the contrary that may be received from any other party or Person. After the release of any HRR Certificates, the Retained Interest
Custodian shall have no liability with respect to the safekeeping of such released HRR Certificates. The Retained Interest Custodian
shall be indemnified and held harmless for any release in connection with the preceding. There shall be, and hereby is, established
by the Certificate Administrator an account which shall be designated the “Third Party Purchaser Safekeeping Account”
and into which the HRR Certificates shall be held and which shall be governed by and subject to this Agreement and the Credit Risk
Retention Compliance Agreement. The HRR Certificates to be delivered in physical form to the Certificate Administrator shall be
delivered as set forth herein. Unless otherwise directed by the Retaining Sponsor, no amounts distributable to the HRR Certificates
shall be remitted to the Third Party Purchaser Safekeeping Account but shall be remitted directly to the Holder of the HRR Certificates
in accordance with written instructions (which shall be in the form of Exhibit VV to this Agreement) provided separately
by the Holder of the HRR Certificates to the Certificate Administrator. Under no circumstances by virtue of safekeeping the HRR
Certificates shall the Certificate Administrator (i) be obligated to bring legal action or institute proceedings against any person
on behalf of the Holder of the HRR Certificates or the Retaining Sponsor or (ii) have any obligation to monitor, supervise or enforce
the performance of any party under the related Credit Risk Retention Compliance Agreement. The Certificate Administrator shall
be entitled to conclusively rely with no obligation to verify, confirm or otherwise monitor the accuracy of any information included
in any written instructions provided in connection with the Third Party Purchaser Safekeeping Account and shall have no liability
in connection therewith, other than with respect to the Certificate Administrator’s obligation to obtain the Retaining Sponsor’s
consent prior to any release of the HRR Certificates. During the Transfer Restriction Period, the Certificate Administrator shall
hold the Definitive Certificate representing the HRR Certificates at the location below, or any other location; provided
the Certificate Administrator has given notice to the Holder of the HRR Certificates of such new location:


 


Wells Fargo Bank NA

Attn: Security Control and Transfer (SCAT) - MAC N9345-010

425 E Hennepin Avenue

Minneapolis, MN 55414


 


On the Closing Date,
the Certificate Administrator shall deliver written confirmations to the Depositor, the Retaining Sponsor and the Third Party Purchaser
substantially in the form of Exhibit UU to this Agreement evidencing its receipt of the HRR Certificates and to the Depositor.


 


The Certificate Administrator
shall make available to the Holder of the HRR Certificates and the Retaining Sponsor a statement of the Third Party Purchaser Safekeeping
Account as mutually agreed upon by the Certificate Administrator, the Retaining Sponsor and the Holder of the HRR Certificates,
and in accordance with the Certificate Administrator’s


 



     -417-


     


    

 


policies and procedures. Any transfer of the HRR Certificates shall
be subject to ARTICLE V of this Agreement.


 


In the event that the
Retaining Sponsor notifies the Certificate Administrator that it has realized upon the HRR Certificates pledged to it under the
Credit Risk Retention Compliance Agreement as a result of the Third Party Purchaser having failed to perform any of its Secured
Obligations (as defined in the Credit Risk Retention Compliance Agreement) and upon written notice and instruction to a Responsible
Officer of the Certificate Administrator at Wells Fargo Bank, National Association, 9062 Old Annapolis Road, Columbia Maryland
21045, Attention: Corporate Trust Services (CMBS) – CSAIL 2017-CX10 of the Retaining Sponsor’s election to realize
upon the HRR Certificates under the Credit Risk Retention Compliance Agreement, the Certificate Administrator shall, in accordance
with any authentication procedures as may be utilized by the Certificate Administrator, reasonably promptly register in the Certificate
Register the Retaining Sponsor as the record owner of the HRR Certificates and fill in the Retaining Sponsor’s name in the
HRR Certificate Power as assignee or as otherwise instructed by the Retaining Sponsor. For the avoidance of doubt, the transfer
or assignment contemplated in this paragraph shall not be subject to any other requirement under Article 5 or otherwise under this
Agreement (including, without limitation, delivery of any required notices or instructions or transferor or transferee certificates,
or delivery to the Certificate Administrator of any medallion guaranty/stamp). The Certificate Administrator shall be indemnified
and held harmless for any actions reasonably taken in connection with the realization, transfer or assignment in connection with
this Section 5.01(c) and in accordance with Section 8.03.


 


(d)           In
the event the Third Party Purchaser seeks to cause the release of any HRR Certificates from the Third Party Safekeeping Account,
the Third Party Purchaser shall simultaneously deliver to the Certificate Administrator, the Retaining Sponsor and the Depositor
(i) an executed written request for such release in the form attached hereto as Exhibit D-5 and (ii) an executed written
request for the Retaining Sponsor’s consent to such release substantially in the form attached hereto as Exhibit D-7.
The Certificate Administrator may not consent to, or otherwise permit, any such release without obtaining the Retaining Sponsor’s
countersigned request for consent. The Certificate Administrator shall be indemnified and held harmless for any release in connection
with the preceding, in accordance with the terms set forth in Section 8.03. The Certificate Administrator shall have no
further obligations with respect to the safekeeping of such released certificates.


 


Section
5.02     Form and Registration. No transfer of any Non-Registered Certificate shall be made
unless that transfer is made pursuant to an effective registration statement under the Securities Act, and effective
registration or qualification under applicable state securities laws, or is made in a transaction which does not require such
registration or qualification. If a transfer (other than one by the Depositor to an Affiliate thereof or by the Initial
Purchaser to Eightfold Real Estate Capital Fund V, L.P. or its Affiliate) is to be made in reliance upon an exemption from
the Securities Act, and under the applicable state securities laws, then either:


 


(a)            Each
Class of the Non-Registered Certificates (other than the HRR Certificates and Class R Certificates) sold to institutions that are
non-United States Securities Persons in Offshore Transactions in reliance on Regulation S under the Act shall initially be


 



     -418-


     


    

 


represented
by a temporary book-entry certificate in definitive, fully registered form without interest coupons, substantially in the applicable
form set forth as an exhibit hereto (each a “Temporary Regulation S Book-Entry Certificate”), which shall be
deposited on the Closing Date on behalf of the purchasers of the Non-Registered Certificates represented thereby with the Certificate
Registrar, at its principal trust office, as custodian, for the Depository, and registered in the name of the Depository or the
nominee of the Depository for the account of designated agents holding on behalf of Euroclear and/or Clearstream. Prior to the
expiration of the 40-day period commencing on the later of the commencement of the offering and the Closing Date (the “Restricted
Period”), beneficial interests in each Temporary Regulation S Book-Entry Certificate may be held only through Euroclear
or Clearstream. After the expiration of the Restricted Period, a beneficial interest in a Temporary Regulation S Book-Entry Certificate
may be exchanged for an interest in the related Regulation S Book-Entry Certificate in the applicable form set forth as an exhibit
hereto in accordance with the procedures set forth in Section 5.03(f). During the Restricted Period, distributions due in
respect of a beneficial interest in a Temporary Regulation S Book-Entry Certificate shall only be made upon delivery to the Certificate
Registrar by Euroclear or Clearstream, as applicable, of a Non-U.S. Beneficial Ownership Certification. After the expiration of
the Restricted Period, distributions due in respect of any beneficial interests in a Temporary Regulation S Book-Entry Certificate
shall not be made to the holders of such beneficial interests unless exchange for a beneficial interest in the Regulation S Book-Entry
Certificate of the same Class is improperly withheld or refused. The aggregate Certificate Balance of a Temporary Regulation S
Book-Entry Certificate or a Regulation S Book-Entry Certificate may from time to time be increased or decreased by adjustments
made on the records of the Certificate Registrar, as custodian for the Depository, as hereinafter provided.


 


On the Closing Date,
the Certificate Administrator shall execute, the Authenticating Agent shall authenticate, and the Certificate Administrator shall
deliver to the Certificate Registrar the Regulation S Book-Entry Certificates, which shall be held by the Certificate Registrar
for purposes of effecting the exchanges contemplated by the preceding paragraph. Wells Fargo Bank, National Association is hereby
initially appointed the Authenticating Agent with the power to act, on the Trustee’s behalf, in the authentication and delivery
of the Certificates in connection with transfers and exchanges as herein provided. If Wells Fargo Bank, National Association is
removed as Certificate Administrator, then Wells Fargo Bank, National Association shall be terminated as Authenticating Agent.
If the Authenticating Agent is terminated, the Trustee shall appoint a successor authenticating agent, which may be the Trustee
or an Affiliate thereof.


 


(b)           Certificates
of each Class of Non-Registered Certificates (other than the HRR Certificates and other than the VRR Interest, the Y&L Towers
VRR Interest and the Standard Highline VRR Interest following the conversion described in Section 5.03(i) hereof during
the Transfer Restriction Period) offered and sold to Qualified Institutional Buyers in reliance on Rule 144A shall be represented
by Rule 144A Book-Entry Certificates, which shall be deposited with the Certificate Registrar or an agent of the Certificate Registrar,
as custodian for the Depository, and registered in the name of the Depository or a nominee of the Depository. The aggregate Certificate
Balance of a Rule 144A Book-Entry Certificate may from time to time be increased or decreased by adjustments made on the records
of the Certificate Registrar, as custodian for the Depository, as hereinafter provided.

(c)            Certificates
of each Class of Non-Registered Certificates that are initially offered and sold to investors that are Institutional Accredited
Investors that are not Qualified Institutional Buyers, the HRR Certificates and the Class R Certificates (the “Non-Book
Entry Certificates”) shall be in the form of Definitive Certificates, substantially in the applicable form set forth
as an exhibit hereto, and shall be registered by the Certificate Registrar in the name of such investors or their nominees who
have provided the Certificate Registrar with an Investment Representation Letter in the form of Exhibit C, and the Certificate
Registrar shall deliver the certificates for such Non-Book Entry Certificates to the respective beneficial owners or owners. The
Loan-Specific Certificates shall not be offered, sold or transferred to investors that are Institutional Accredited Investors who
are not also Qualified Institutional Buyers. For the avoidance of doubt, the Class V, Class R and Class Z Certificates and the
HRR Certificates shall only be in the form of Definitive Certificates, and the Certificates evidencing the VRR Interest, the Y&L
Towers VRR Interest and the Standard Highline VRR Interest shall be converted following their initial issuance to the form of Definitive
Certificates pursuant to Section 5.02(i) and shall thereafter at all times during the Transfer Restriction Period be held
in such form.


 


(d)           Owners
of beneficial interests in Book-Entry Certificates of any Class shall not be entitled to receive physical delivery of certificated
Certificates unless: (i) the Depository advises the Certificate Registrar in writing that the Depository is no longer willing or
able to discharge properly its responsibilities as depository with respect to the Book-Entry Certificates of such Class or ceases
to be a Clearing Agency, and the Certificate Registrar and the Depository are unable to locate a qualified successor within ninety
(90) days of such notice or (ii) the Trustee has instituted or has been directed to institute any judicial proceeding to enforce
the rights of the Holders of such Class and the Trustee has been advised by counsel that in connection with such proceeding it
is necessary or appropriate for the Certificate Registrar to obtain possession of the Certificates of such Class; provided,
however, that under no circumstances will certificated Non-Registered Certificates be issued to beneficial owners of a Temporary
Regulation S Book-Entry Certificate. Upon notice of the occurrence of any of the events described in clause (i) or (ii)
above with respect to any Certificates of a Class that are in the form of Book-Entry Certificates and upon surrender by the Depository
of any Book-Entry Certificate of such Class and receipt from the Depository of instructions for re-registration, the Certificate
Registrar shall issue Certificates of such Class in the form of Definitive Certificates (bearing, in the case of a Definitive Certificate
issued for a Rule 144A Book-Entry Certificate, the same legends regarding transfer restrictions borne by such Book-Entry Certificate),
and thereafter the Certificate Registrar shall recognize the Holders of such Definitive Certificates as Certificateholders under
this Agreement. Unless and until Definitive Certificates are issued in respect of a Class of Book-Entry Certificates, beneficial
ownership interests in such Class of Certificates will be maintained and transferred on the book entry records of the Depository
and Depository Participants, and all references to actions by Holders of such Class of Certificates will refer to action taken
by the Depository upon instructions received from the related registered Holders of Certificates through the Depository Participants
in accordance with the Depository’s procedures and, except as otherwise set forth herein, all references herein to payments,
notices, reports and statements to Holders of such Class of Certificates will refer to payments, notices, reports and statements
to the Depository or its nominee as the registered Holder thereof, for distribution to the related registered Holders of Certificates
through the Depository Participants in accordance with the Depository’s procedures.

(e)            Other
than as provided for in Section 5.03(i), any VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest
shall only be held as a Definitive Certificate in a Retained Interest Safekeeping Account by the Certificate Administrator (the

Upon receipt by the Certificate Registrar, as registrar, at its office designated in Section 5.07, of (1) instructions from
Euroclear or Clearstream, if applicable, and the Depository, directing the Certificate Registrar, as registrar, to credit or cause
to be credited a beneficial interest in the Rule 144A Book-Entry Certificate equal to the beneficial interest in the Temporary
Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate to be exchanged, such instructions to contain information
regarding the participant account with the Depository to be credited with such increase, (2) with respect to a transfer of an interest
in the Regulation S Book-Entry Certificate, information regarding the participant account of the Depository to be debited with

given by the holder of such beneficial interest and stating that the Person transferring such interest in the Temporary Regulation

(f)             Temporary
Regulation S Book-Entry Certificate to Regulation S Book-Entry Certificate. Interests in a Temporary Regulation S Book-Entry
Certificate as to which the Certificate Registrar has received from Euroclear or Clearstream, as the case may be, a certificate
(a “Non-U.S. Beneficial Ownership Certification”) to the effect that Euroclear or Clearstream, as applicable,
has received a certificate substantially in the form of Exhibit L hereto from the holder


 



     -424-


     


    

 


of a beneficial interest in such
Temporary Regulation S Book-Entry Certificate, shall be exchanged after the Restricted Period, for interests in the Regulation
S Book-Entry Certificate of the same Class. The Certificate Registrar shall effect such exchange by delivering to the Depository
for credit to the respective accounts of such holders, a duly executed and authenticated Regulation S Book-Entry Certificate, representing
the aggregate Certificate Balance of interests in the Temporary Regulation S Book-Entry Certificate initially exchanged for interests
in the Regulation S Book-Entry Certificate. The delivery to the Certificate Registrar by Euroclear or Clearstream of the certificate
or certificates referred to above may be relied upon by the Depositor and the Certificate Registrar as conclusive evidence that
the certificate or certificates referred to therein has or have been delivered to Euroclear or Clearstream pursuant to the terms
of this Agreement and the Temporary Regulation S Book-Entry Certificate. Upon any exchange of interests in the Temporary Regulation
S Book-Entry Certificate for interests in the Regulation S Book-Entry Certificate, the Certificate Registrar shall endorse the
Temporary Regulation S Book-Entry Certificate to reflect the reduction in the Certificate Balance represented thereby by the amount
so exchanged and shall endorse the Regulation S Book-Entry Certificate to reflect the corresponding increase in the amount represented
thereby. Until so exchanged in full and except as provided therein, the Temporary Regulation S Book-Entry Certificate, and the
Certificates evidenced thereby, shall in all respects be entitled to the same benefits under this Agreement as the Regulation S
Book-Entry Certificate and Rule 144A Book-Entry Certificate authenticated and delivered hereunder.


 


(g)            Non-Book
Entry Certificate to Book-Entry Certificate. If a holder of a Non-Book Entry Certificate (other than (a) a Class R Certificate,
(b) a Class Z Certificate or (c) an HRR Certificate or any Certificate evidencing the VRR Interest, Y&L Towers VRR Interest
or Standard Highline VRR Interest during the Transfer Restriction Period) wishes at any time to exchange its interest in such Non-Book
Entry Certificate for an interest in a Book-Entry Certificate of the same Class, or to transfer all or part of such Non-Book Entry
Certificate to a Person who is entitled to take delivery thereof in the form of an interest in a Book-Entry Certificate, such holder
may, subject to the rules and procedures of Euroclear or Clearstream, if applicable, and the Depository, cause the exchange of
all or part of such Non-Book Entry Certificate for an equivalent beneficial interest in the appropriate Book-Entry Certificate
of the same Class. Upon receipt by the Certificate Registrar, as registrar, at its office designated in Section 5.07, of
(1) such Non-Book Entry Certificate, duly endorsed as provided herein, (2) instructions from such holder directing the Certificate
Registrar, as registrar, to credit, or cause to be credited, a beneficial interest in the applicable Book-Entry Certificate equal
to the portion of the Certificate Balance of the Non-Book Entry Certificate to be exchanged, such instructions to contain information
regarding the participant account with the Depository to be credited with such increase and (3) a certificate in the form of Exhibit
M hereto (in the event that the applicable Book-Entry Certificate is the Temporary Regulation S Book-Entry Certificate), in
the form of Exhibit N hereto (in the event that the applicable Book-Entry Certificate is the Regulation S Book-Entry Certificate)
or in the form of Exhibit O hereto (in the event that the applicable Book-Entry Certificate is the Rule 144A Book-Entry
Certificate), then the Certificate Registrar, as registrar, shall cancel, or cause to be canceled, all or part of such Non-Book
Entry Certificate, shall, if applicable, execute, authenticate and deliver to the transferor a new Non-Book Entry Certificate equal
to the aggregate Certificate Balance of the portion retained by such transferor and shall instruct the Depository to increase,
or cause to be increased, such Book-Entry Certificate by the aggregate Certificate Balance of the portion of the Non-Book Entry


 



     -425-


     


    

 


Certificate to be exchanged and to credit, or cause to be credited, to the account of the Person specified in such instructions
a beneficial interest in the applicable Book-Entry Certificate equal to the Certificate Balance of the portion of the Non-Book
Entry Certificate so canceled. Upon the written direction of the Depositor (which may be by email to cts.cmbs.bond.admin@wellsfargo.com)
or its Affiliate, the Certificate Registrar shall execute any instrument as may be reasonably required by the Depository to effect
such exchange.


 


(h)            Non-Book
Entry Certificates on Initial Issuance Only. Subject to the issuance of Definitive Certificates, if and when permitted by Section
5.02(d), and subject to the issuance and transfer of the VRR Interest, the Y&L Towers VRR Interest and the Standard Highline
VRR Interest in accordance with Section 5.03(i), no Non-Book Entry Certificate shall be issued to a transferee of an interest
in any Rule 144A Book-Entry Certificate, Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate or
to a transferee of a Non-Book Entry Certificate (or any portion thereof).


 


(i)             Transfers
of VRR Interests, Y&L Towers VRR Interests or Standard Highline VRR Interests. At all times, if a Transfer of all or a
portion of the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable, is to be made,
then the Certificate Registrar shall refuse to register such transfer unless it receives (and, upon receipt, may conclusively rely
upon) (i) a certification from such Certificateholder’s prospective Transferee substantially in the form attached hereto
as Exhibit D-3, which such certification must be countersigned by the Retaining Sponsor and Depositor with a medallion stamp
guarantee of the Retaining Sponsor and (ii) a certification from the Certificateholder desiring to effect such transfer substantially
in the form attached hereto as Exhibit D-4, which such certification must be countersigned by the Retaining Sponsor and
the Depositor with a medallion stamp guarantee of the Retaining Sponsor. Upon receipt of the foregoing certifications, the Certificate
Registrar shall, subject to Section 5.02(e) and Section 5.03(a), reflect all or any such portion of the VRR Interest,
the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as applicable, in the name of the prospective Transferee.
For the avoidance of doubt, other than at initial issuance, in no event shall a VRR Interest, the Y&L Towers VRR Interest or
the Standard Highline VRR Interest be held as a Book-Entry Certificate during the Transfer Restriction Period; provided
that, each Certificate representing the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest, as
applicable, shall on the Closing Date be issued in book-entry form and shall initially be held as a Book-Entry Certificate; however,
upon initial issuance on the Closing Date, the Certificate Administrator is hereby instructed by the Depositor to exchange the
Book-Entry Certificate(s) representing the VRR Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest,
as applicable, for a Definitive Certificate as soon as practicable after the Closing Date but no later than two (2) Business Days
after the Closing Date and shall hold each Definitive Certificate evidencing the VRR Interest, the Y&L Towers VRR Interest
or the Standard Highline VRR Interest, as applicable, in safekeeping pursuant to Section 5.02(e). Any attempted or purported
transfer in violation of this Section 5.03(i) shall be null and void ab initio and shall vest no rights in any purported
transferee and shall not relieve the transferor of any obligations with respect to the applicable Certificates.


 


(j)             Other
Exchanges. In the event that a Book-Entry Certificate is exchanged for a Definitive Certificate, such Certificates may be exchanged
only in accordance with such procedures as are substantially consistent with the provisions of subsections (c) through (f)
above


 



     -426-


     


    

 


(including the certification requirements intended to ensure that such transfers comply with Rule 144A or Regulation S under
the Act, at the case may be) and such other procedures as may from time to time be adopted by the Certificate Registrar.


 


(k)            Restricted
Period. Prior to the termination of the Restricted Period with respect to the issuance of the Certificates, transfers of interests
in the Temporary Regulation S Book-Entry Certificate to U.S. persons (as defined in Regulation S) shall be limited to transfers
made pursuant to the provisions of subsection (e) above.


 


(l)             If
Non-Registered Certificates are issued upon the transfer, exchange or replacement of Certificates bearing a restrictive legend
relating to compliance with the Act, or if a request is made to remove such legend on Certificates, the Non-Registered Certificates
so issued shall bear the restrictive legend, or such legend shall not be removed, as the case may be, unless there is delivered
to the Certificate Registrar such satisfactory evidence, which may include an Opinion of Counsel that neither such legend nor the
restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A
or Regulation S under the Act. Upon provision of such satisfactory evidence, the Certificate Registrar shall authenticate and deliver
Certificates that do not bear such legend.


 


(m)           All
Certificates surrendered for registration of transfer and exchange shall be canceled and subsequently destroyed by the Certificate
Registrar in accordance with the Certificate Registrar’s customary procedures.


 


(n)           With
respect to the ERISA Restricted Certificates, no sale, transfer, pledge or other disposition (other than any initial transfer to

purchase and holding of such Certificates by such insurance company would be exempt from the prohibited transaction provisions
of ERISA and the Code under Sections I and III of Prohibited Transaction Class Exemption 95-60 (or, in the case of a Plan subject
to Similar Law, would not result in a non-exempt violation of Similar Law) or (ii) if such Certificate which may be held only by
a person not described in clauses (A) or (B) above, is presented for registration in the name of a purchaser or transferee

violation of any Similar Law, and will not subject the Trustee, the Certificate Administrator, the Master Servicer, the Special
Servicer, the Initial Purchaser, the Loan-Specific Initial Purchasers, the Underwriters, the Operating Advisor or the Depositor
to any obligation or liability (including obligations or liabilities under ERISA, Section 4975 of the Code or any such Similar

that would constitute or result in a prohibited transaction under ERISA, Section 4975 of the Code or any Similar Law, or would
otherwise violate the provisions of this Section 5.03(n) shall be deemed absolutely null and void ab initio, to the
extent permitted under applicable law.

have agreed to be bound by the following provisions and the rights of each Person acquiring any Residual Ownership Interest are
expressly subject to the following provisions:


 


(i)           Each
Person acquiring or holding any Residual Ownership Interest shall be a Permitted Transferee and shall not acquire or hold such
Residual Ownership Interest as


 



     -429-


     


    

 


agent (including a broker, nominee or other middleman) on behalf of any Person that is not a Permitted
Transferee. Any such Person shall promptly notify the Certificate Registrar of any change or impending change in its status (or
the status of the beneficial owner of such Residual Ownership Interest) as a Permitted Transferee. Any acquisition described in
the first sentence of this Section 5.03(o) by a Person who is not a Permitted Transferee or by a Person who is acting as
an agent of a Person who is not a Permitted Transferee shall be void ab initio and of no effect, and the immediately preceding
owner who was a Permitted Transferee shall be restored to registered and beneficial ownership of the Residual Ownership Interest
as soon and as fully as possible.


 


(ii)          No
Residual Ownership Interest may be Transferred, and no such Transfer shall be registered in the Certificate Register, without the
express written consent of the Certificate Registrar, and the Certificate Registrar shall not recognize the Transfer, and such
proposed Transfer shall not be effective, without such consent with respect thereto. In connection with any proposed Transfer of
any Residual Ownership Interest, the Certificate Registrar shall, as a condition to such consent, (x) require the proposed transferee
to deliver, and the proposed transferee shall deliver to the Certificate Registrar and to the proposed transferor, an affidavit
in substantially the form attached as Exhibit D-1 (a “Transferee Affidavit”) of the proposed transferee
(A) that such proposed transferee is a Permitted Transferee and (B) stating that (1) the proposed transferee historically has paid
its debts as they have come due and intends to do so in the future, (2) the proposed transferee understands that, as the holder
of a Residual Ownership Interest, it may incur liabilities in excess of cash flows generated by the residual interest, (3) the
proposed transferee intends to pay taxes associated with holding the Residual Ownership Interest as they become due, (4) the proposed
transferee will not cause income with respect to the Residual Ownership Interest to be attributable to a foreign permanent establishment
or fixed base, within the meaning of an applicable income tax treaty, of such proposed transferee or any other U.S. Tax Person,
(5) the proposed transferee will not transfer the Residual Ownership Interest to any Person that does not provide a Transferee
Affidavit or as to which the proposed transferee has actual knowledge that such Person is not a Permitted Transferee or is acting
as an agent (including a broker, nominee or other middleman) for a Person that is not a Permitted Transferee, and (6) the proposed
transferee expressly agrees to be bound by and to abide by the provisions of this Section 5.03(o) and (y) other than in
connection with the initial issuance of a Class R Certificate, require a statement from the proposed transferor substantially in
the form attached as Exhibit D-2 (the “Transferor Letter”), that the proposed transferor has no actual
knowledge that the proposed transferee is not a Permitted Transferee and has no actual knowledge or reason to know that the proposed
transferee’s statements in its Transferee Affidavit are false.


 


(iii)   
    Notwithstanding the delivery of a Transferee Affidavit by a proposed transferee under clause
(ii) above, if a Responsible Officer of the Certificate Registrar has actual knowledge that the proposed transferee is
not a Permitted Transferee, no Transfer to such proposed transferee shall be effected and such proposed Transfer shall not be
registered on the Certificate Register; provided, however, that the Certificate Registrar shall not be required
to conduct any independent investigation to determine whether a proposed transferee is a Permitted Transferee. Upon notice to
the Certificate Registrar


 



     -430-


     


    

 


that there has occurred a Transfer to any Person that is a Disqualified Organization or an agent
thereof (including a broker, nominee or middleman) in contravention of the foregoing restrictions, and in any event not later
than sixty (60) days after a request for information from the transferor of such Residual Ownership Interest or such agent,
the Certificate Registrar agrees to furnish to the Internal Revenue Service and the transferor of such Residual Ownership
Interest or such agent such information necessary to the application of Section 860E(e) of the Code as may be required by the
Code, including, but not limited to, the present value of the total anticipated excess inclusions with respect to such Class
R Certificate (or portion thereof) for periods after such Transfer. At the election of the Certificate Registrar, the
Certificate Registrar may charge a reasonable fee for computing and furnishing such information to the transferor or to
such agent referred to above; provided, however, that such Persons shall in no event be excused from furnishing
such information.


 


(p)            The
Class R Certificates may only be transferred to and owned by Qualified Institutional Buyers.


 


(q)           Other
than with respect to a transfer made pursuant to the last paragraph of Section 5.01(c), if a transfer of the HRR Certificates
is to be made, then the Certificate Registrar shall refuse to register such transfer unless it receives (and, upon receipt, may
conclusively rely upon) (i) a certification from such Certificateholder’s prospective transferee substantially in the form
attached hereto as Exhibit D-5, which such certification must be countersigned by the Retaining Sponsor and Depositor with
a medallion stamp guarantee of the Retaining Sponsor and (ii) a certification from the Certificateholder desiring to effect such
transfer substantially in the form attached hereto as Exhibit D-6, which such certification must be countersigned by the
Retaining Sponsor and Depositor with a medallion stamp guarantee of the Retaining Sponsor. Upon receipt of the foregoing certifications,
the Certificate Registrar shall, subject to Section 5.01(c) and Section 5.03, reflect the HRR Certificates in the
name of the prospective transferee. For the avoidance of doubt, in no event shall the HRR Certificates be held as a Global Certificate
during the Transfer Restriction Period.


 


(r)             Notwithstanding
any other provision of this Agreement, the Certificate Administrator shall comply with all federal withholding requirements respecting
payments to Certificateholders and other payees of interest or original issue discount that the Certificate Administrator reasonably
believes are applicable under the Code. The consent of Certificateholders or payees shall not be required for such withholding,
and the Certificateholders shall be required to provide the Certificate Administrator with such forms and other such information
reasonably required by the Certificate Administrator. If the Certificate Administrator does withhold any amount from interest or
original issue discount payments or advances thereof to any Certificateholder or payee pursuant to federal withholding requirements,
the Certificate Administrator shall indicate the amount withheld to such Person. Such amounts shall be deemed to have been distributed
to such Persons for all purposes of this Agreement.

transfer of the Non-Registered Certificates owned by such Certificate Owner will be permitted unless the purchaser provides certification
that the transfer complies with such restrictions, as described in this Section 5.03(s).


 


(iv)           Such

(at such Certificateholder’s sole cost and expense) access during normal business hours to a current list of the
Certificateholders as of the most recent Record Date as they appear in the Certificate Register. Every Certificateholder, by
receiving and holding a Certificate, agrees that the Certificate Registrar shall not be held accountable by reason of the

Highline Exchangeable Group, and upon the surrender of the Certificates evidencing such Tranche Percentage, the Certificate Administrator,
on behalf of the Trustee, shall deliver (by the means set forth in the penultimate sentence of Section 5.09(g)) the corresponding
Exchangeable Group, Y&L Towers Exchangeable Group or Standard Highline Exchangeable Group, respectively, of Certificates to
which such Certificateholder is entitled as set forth in Section 5.09(c).


 


(f)        In

received by such Holder, and (iii) in the case of any related Global Certificate, the Certificate Registrar or the Certificate
Administrator, as applicable, shall approve the instructions at the Depository and make appropriate notations on the Global Certificate
for each related Class


 



     -438-


     


    

 


of Certificates to reflect such reductions and increases. Any transfer of a Certificate evidencing the VRR
Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest to (i) a Plan subject to ERISA or Section 4975 of the Code
relying on Prohibited Transaction Exemption 89-90 or (ii) an insurance company general account relying on Sections I and III of
PTCE 95-60 shall be effected through Credit Suisse Securities (USA) LLC or Natixis Securities Americas LLC.


 


(g)       For
all exchanges other than any exchange effectuated by the Depositor pursuant to Section 5.09(d), in order to effect an exchange
of an Exchangeable Group, Y&L Towers Exchangeable Group or Standard Highline Exchangeable Group of Certificates, the Certificateholder
shall notify the Certificate Administrator in writing or by e-mail at cts.cmbs.bond.admin@wellsfargo.com (with a subject line referencing
“CSAIL 2017-CX10” and setting forth the proposed Exchange Date) no later than three (3) Business Days before the proposed
exchange date (the “Exchange Date”). The Exchange Date may be any Business Day other than the first or last
Business Day of the month. An exchange notice must (i) be set forth on the applicable Certificateholder’s letterhead, (ii)
carry a medallion stamp guarantee and (iii) set forth the following information: the CUSIP Number of each Certificate to be exchanged
and each Certificate to be received; the original and outstanding Certificate Balance or Notional Amount, as applicable, of the
Certificates to be exchanged and the original and outstanding Certificate Balance or Notional Amount, as applicable, of the Certificates
to be received; the Certificateholder’s Depository participant number, if applicable; and the proposed Exchange Date. The
Certificateholder and the Certificate Registrar shall utilize the “deposit and withdrawal system” at the Depository
to effect the exchange of the applicable Certificates that are Global Certificates. A notice shall become irrevocable on the second
(2nd) Business Day before the proposed Exchange Date. Global Certificates shall be exchangeable on the books of the Depository
for the corresponding Global Certificates on and after the Closing Date, by notice to the Certificate Administrator substantially
in the form of Exhibit TT.


 


(h)       The
Certificate Administrator shall make the first distribution on a Certificate received by a Certificateholder in any exchange on

Section
5.10     Voting Procedures. With respect to any matters submitted to Certificateholders for a vote, the Certificate
Administrator shall administer such vote through the Depository with respect to Book-Entry Certificates and directly with
registered Holders by mail with respect to Definitive Certificates. In each case, such vote shall be administered in
accordance with the following procedures, unless different procedures are otherwise described herein with respect to a
specific vote:


 


(a)       Any
matter submitted to Certificateholders for a vote shall be announced in a notice prepared by the Certificate Administrator. Such
notice shall include the record date


 



     -439-


     


    

 


determined by the Certificate Administrator for purposes of the vote and a voting deadline
which shall be no less than thirty (30) days and no later than sixty (60) days after the date such notice is distributed. The notice
and related ballot shall be sent to Holders of Book-Entry Certificates through the Depository and by mail to the registered Holders
of Definitive Certificates. In addition, the notice and related ballot shall be posted to the Certificate Administrator’s
Website. Notices delivered in this manner shall be considered delivered to all Holders regardless of whether any Holder actually
receives the notice and ballot.


 


(b)       In
connection with any vote administered pursuant to this Agreement, voting Holders shall be required to certify their holdings in
the manner set forth on the ballot, unless a specific manner is otherwise provided herein. Holders may only vote in accordance
with their Voting Rights. Voting Rights with respect to any outstanding Class of Certificates shall be calculated by the Certificate
Administrator in accordance with the definition of Voting Rights as of the record date for the vote. Only Classes with an outstanding
Certificate Balance or Notional Amount greater than zero as of the record date of the vote shall be permitted to vote. Once a Holder
has cast its vote, the vote may be changed or retracted on or before the vote deadline. Any changes or retractions shall be communicated
by the Certificateholder to the Certificate Administrator in writing on a ballot. After the vote deadline has passed, votes may
not be changed or retracted by any Holder unless the Holder wishing to change or retract its vote holds a sufficient portion of
the Voting Rights such that the Holder, by its vote alone, could approve or deny the proposition subject to a vote without taking
into consideration the votes cast by any other Holder. Transferees or purchasers of any Class of Certificates are subject to and
shall be bound by all votes of Holders initiated or conducted prior to its acquisition of such Certificate.


 


(c)       The
Certificate Administrator may take up to fifteen (15) Business Days to tabulate the results of any vote. The Certificate Administrator
shall use its reasonable efforts to resolve any illegible or incomplete ballots received prior to the voting deadline. Illegible
or incomplete ballots that are received on the voting deadline or that cannot be resolved by the voting deadline shall not be counted.
Promptly after the votes are tabulated, the Certificate Administrator shall prepare a notice announcing the results of the vote.
Such notice shall include the percentage of Voting Rights in favor of the proposition, the percentage against the proposition and
the percentage abstaining. In addition, the notice will announce whether the proposition has been adopted by Certificateholders.
The notice shall be distributed in accordance with the methods described in Section 5.10(a) above. The Certificate Administrator
shall also include such notice on the Form 10-D prepared in connection with the distribution period that corresponds with the date
such notice is distributed. All vote tabulations shall be final and the Certificate Administrator shall not, absent manifest error,
re-tabulate the votes or conduct a new vote for the same proposition.


 


(d)       Any
and all reasonable expenses incurred by the Certificate Administrator in connection with administering any vote shall be borne
by the Trust. The Certificate Administrator is under no obligation to advise Holders about the matter being voted on or answer
questions other than process-related questions regarding the administration of the vote.


 


(e)       If
any party to this Agreement believes a vote of Certificateholders is needed for some matter related to the administration of the
Trust that is not specifically


 






     -440-


     


    

 


contemplated herein, such party may request the Certificate Administrator to conduct a vote and
the Certificate Administrator will conduct the requested vote in accordance with these procedures. Unless specifically provided
herein, all such votes require a majority of Certificateholders to carry a proposition.

do business as a foreign entity in each jurisdiction in which qualification is or shall be necessary to protect the validity and

duties under this Agreement.


 


(b)         The
Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer each may be
merged or consolidated with or into any Person, or transfer all or substantially all of its assets (which may be limited to all
or substantially all of its assets related to commercial mortgage loan servicing or commercial mortgage surveillance, as the case
may be) to any Person, in which case any Person resulting from any merger or consolidation to which the Depositor, the Master Servicer,
the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer shall be a party, or any Person succeeding to
the business of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer,
shall be the successor of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations
Reviewer (such Person, in the case of the Master Servicer or the Special Servicer, in each of the foregoing cases, the “Surviving
Entity”), as the case may be, hereunder, without the execution or filing of any paper (other than an assumption agreement
wherein the successor shall agree to perform the obligations of and serve as the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, or the Asset Representations Reviewer, as the case may be, in accordance with the terms of this Agreement)
or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided,
however, that with respect to such merger, consolidation or succession, Rating Agency Confirmation is received from each
Rating Agency with respect to the Classes of Certificates and, with respect to


 






     -447-


     


    

 


any class
of Serviced Companion Loan Securities, a confirmation is received from each applicable rating agency that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates as described in Section 3.25); provided, further, that if the Master Servicer, the Special Servicer,
the Operating Advisor or the Asset Representations Reviewer enters into a merger and the Master Servicer, the Special Servicer,
the Operating Advisor or the Asset Representations Reviewer, as applicable, is the Surviving Entity under applicable law, the
Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, as applicable, shall not,
as a result of the merger, be required to provide a Rating Agency Confirmation with respect to ratings of the Classes of Certificates
or, with respect to any class of Serviced Companion Loan Securities, a confirmation of the rating agencies that such action will
not result in the downgrade, withdrawal or qualification of its then-current ratings; provided, further, that for
so long as the Trust, and, with respect to any Companion Loan included as part of the trust in a related Other Securitization,
is subject to the reporting requirements of the Exchange Act, if the Master Servicer, the Special Servicer, the Operating Advisor
or the Asset Representations Reviewer notifies the Depositor in writing (a “Merger Notice”) of any such merger,
consolidation, conversion or other change in form, and the Depositor or the depositor in such Other Securitization, as the case

in writing that the Depositor or the depositor in such Other Securitization, as the case may be, has discovered that such successor
entity has not complied with its Exchange Act reporting obligations under any other commercial mortgage loan securitization (and
specifically identifying the instance of noncompliance), then it shall be an additional condition to such succession that the
Depositor or the depositor in such Other Securitization, as the case may be, shall have consented (which consent shall not be
unreasonably withheld or delayed) to such successor entity. Notwithstanding the foregoing, no Master Servicer, Special Servicer
or Operating Advisor may remain the Master Servicer, the Special Servicer or Operating Advisor, as applicable, under this Agreement
after (x) being merged or consolidated with or into any Person that is a Prohibited Party, or (y) transferring all or substantially
all of its assets to any Person if such Person is a Prohibited Party, except to the extent (i) the Master Servicer, the Special
Servicer or Operating Advisor, as applicable, is the Surviving Entity of such merger, consolidation or transfer and has been and
continues to be in compliance with its Regulation AB reporting obligations hereunder or (ii) the Depositor consents to such merger,
consolidation or transfer, which consent shall not be unreasonably withheld. If, within sixty (60) days following the date of
delivery of the Merger Notice to the Depositor or the depositor in such Other Securitization, as the case may be, the Depositor
or depositor in such Other Securitization, as the case may be, shall have failed to notify the Master Servicer or the Special
Servicer, as applicable, in writing of the Depositor’s determination, or depositor’s determination, in the case of
an Other Securitization, to grant or withhold such consent, such failure shall be deemed to constitute a grant of such consent.
If the conditions to the provisions in the second preceding sentence are not met, the Trustee may terminate, and if the conditions
set forth in the third proviso of the third preceding sentence are not met the Trustee shall terminate, the applicable Surviving
Entity’s servicing of the Mortgage Loans and the Trust Subordinate Companion Loans pursuant hereto, such termination to
be effected in the manner set forth in Section 7.01.

nor the Certificate Administrator (including in its capacity as Custodian) shall be liable for special, punitive, indirect or
consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee or the
Certificate Administrator has been advised of the likelihood of such loss or damage and regardless of the form of action.

Paying Agent), the
Special Servicer, the Asset Representations Reviewer or the Operating Advisor to be genuine and to have been signed or presented
by the proper party or parties and each of them may consult with counsel, in which case any written advice of counsel or Opinion
of Counsel shall be full and complete authorization and protection with respect to any action taken or suffered or omitted by
it hereunder in good faith and in accordance with such advice or Opinion of Counsel.


 


(b)         None
of the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Operating
Advisor and the Asset Representations Reviewer shall be under any obligation to appear in, prosecute or defend any legal or administrative
action (whether in equity or at law), proceeding, hearing or examination that is not incidental to its respective duties under
this Agreement or which in its opinion may involve it in any expense or liability not recoverable from the Trust; provided,
however, that each of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations
Reviewer may in its discretion undertake any such action, proceeding, hearing or examination that it may deem necessary or desirable
in respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders (and,
in the case of any Serviced Whole Loan, the rights of the Certificateholders and the holders of a Serviced Companion Loan (as a
collective whole) taking into account the subordinate or pari passu nature of such Serviced Companion Loan); provided,
however, that if a Serviced Whole Loan and/or the holder of any related Companion Loan are involved, such expenses, costs
and liabilities will be payable out of funds related to the applicable Serviced Whole Loan in accordance with the related Intercreditor
Agreement and will also be payable out of the other funds in the Collection Account if amounts on deposit with respect to such
Serviced Whole Loan are insufficient therefor. If any such expenses, costs or liabilities relate to a Mortgage Loan or Companion
Loan, then any subsequent recovery on that Mortgage Loan or Companion Loan, as applicable, will be used to reimburse the Trust
for any amounts advanced for the payment of such expenses, costs or liabilities. In such event, the legal expenses and costs of
such action, proceeding, hearing or examination and any liability resulting therefrom shall be expenses, costs and liabilities
of the Trust, and the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer,
the Asset Representations Reviewer and the Operating Advisor shall be entitled to be reimbursed therefor out of amounts attributable
to the Mortgage Loans or the Companion Loan on deposit in the Collection Account (including, without duplication, any subaccount
thereof), as provided by Section 3.05(a)(xii).

of the Master Servicer) and the Trust and any partner, director, officer, shareholder, member, manager, employee or agent thereof,
and hold them harmless, from and against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related
costs, judgments, and any other costs, liabilities, fees and expenses (including costs of enforcement of this indemnity) that any
of them may sustain arising from or as a result of any willful misconduct, bad faith or negligence of the Master Servicer or the
Special Servicer, as the case may be, in the performance of its obligations and duties under this Agreement or by reason of negligent
disregard by the Master Servicer or the Special

Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Depositor) and pay all expenses in
connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered
against it or them in respect of such claim. Any failure to so notify the Master Servicer or the Special Servicer, as the case

unless the Master Servicer’s or the Special Servicer’s, as the case may be, defense of such claim is materially prejudiced
thereby.

defense of such claim is materially prejudiced thereby.

Representations Reviewer or the Depositor) and pay all expenses in connection therewith, including counsel fees, and promptly pay,

obligations and duties hereby imposed on each of them except upon (a) determination that such party’s duties hereunder
are no longer permissible under applicable law or (b) in the case of the Master Servicer or the Special Servicer, upon the
appointment of, and the acceptance of such appointment by, a successor master servicer or special servicer, as applicable,
and receipt by the Certificate Administrator and the Trustee of Rating Agency Confirmation from each Rating Agency and a
confirmation of any applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating
agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25). Any such determination permitting
the resignation of the Master Servicer or the Special Servicer pursuant to clause (a) above shall be evidenced by an
Opinion of Counsel (at the expense of the resigning party) to such effect delivered to the Trustee and (prior to the
occurrence and continuance of a Consultation Termination Event) the Directing Certificateholder. No such resignation by the
Master Servicer or the Special Servicer shall become effective until the Trustee or a successor master servicer or successor
special servicer, as applicable, shall have assumed the Master Servicer’s or the Special Servicer’s, as
applicable, responsibilities and obligations in accordance with Section 7.02 and no such resignation by the Master
Servicer or the Special Servicer shall become effective until the Certificate Administrator shall have filed any required
Form 8-K pursuant to Section 11.07 hereof and any other Form 8-K filings have been completed with respect to any
related Companion Loan. Upon any termination (as described in Section 7.01(c)) or resignation of the Master Servicer
or the Special Servicer, pursuant to this Section 6.05, the Master Servicer or the Special Servicer, as applicable,
shall have the right and opportunity to appoint any successor master servicer or special servicer with respect to this Section
6.05; provided that, such successor master servicer or special servicer shall not be the Asset Representations
Reviewer, the Operating Advisor or one of their respective Affiliates and (prior to the occurrence and continuance of a
Control Termination Event) such successor special servicer is approved by the Directing Holder, such approval not to be
unreasonably withheld. The resigning party shall pay all costs and expenses (including costs and expenses incurred by the
Trustee and the Certificate Administrator) associated with a transfer of its duties pursuant to this Section
6.05. Except as provided in Section 7.01(c), in no event shall the Master Servicer or the Special Servicer have
the right to appoint any successor master servicer or special servicer if such Master Servicer or Special Servicer, as
applicable, is terminated or removed pursuant to Section 7.01.


 


Section 6.06      Rights
of the Depositor in Respect of the Master Servicer and the Special Servicer. The Depositor may, but is not obligated to, enforce

of the Master Servicer or the Special Servicer, as


 






     -454-


     


    

 


applicable,
hereunder; provided, however, that the Master Servicer and the Special Servicer shall not be relieved of any of
their respective obligations hereunder by virtue of such performance by the Depositor or its designee. The Depositor shall not
have any responsibility or liability for any action or failure to act by the Master Servicer or the Special Servicer and is not
obligated to supervise the performance of the Trustee, the Master Servicer, the Operating Advisor or the Special Servicer under
this Agreement or otherwise.


 


Section 6.07      The
Master Servicer and the Special Servicer as Certificate Owner. The Master Servicer, the Special Servicer or any Affiliate
thereof may become the Holder of (or, in the case of a Book-Entry Certificate, Certificate Owner with respect to) any Certificate
with (except as otherwise set forth in the definition of “Certificateholder”) the same rights it would have if it
were not the Master Servicer, the Special Servicer or an Affiliate thereof.


 


Section 6.08      The
Directing Holder and the Risk Retention Consultation Party. (a) (A) The Directing Holder shall be entitled to advise (1) the
Special Servicer with respect to the related Specially Serviced Loans other than any applicable Excluded Loan with respect to
the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling
Class (2) the Special Servicer, with respect to the related Non-Specially Serviced Loans (other than any applicable Excluded Loan

such consultation set forth in this Section 6.08(a). Notwithstanding anything herein to the contrary, (i) except as set
forth in, and in any event subject to Section 6.08(b), to the second and third paragraphs of this Section 6.08(a)
and to the provisos that follow clause (xiii) below, with respect to any Mortgage Loan (other than any Non-Serviced Mortgage
Loan, any Servicing Shift Mortgage Loan or any Excluded Loan) or any Serviced Whole Loan, for so long as no Control Termination
Event has occurred and is continuing, the Special Servicer shall not be permitted to take any action set forth in clauses (i)
through (xiii) below (each a “Major Decision”) as to which the Directing Holder has objected in
writing within ten (10) Business Days (or thirty (30) days with respect to clause (x) below) after receipt of the written
analysis (provided that if such written objection has not been received by the Special Servicer within such ten (10) Business
Day (or thirty (30) day) period, then such Directing Holder will be deemed to have approved such action) (provided that
the foregoing consent rights of such Directing Holder shall not apply to any applicable Excluded Loan) and (ii) the Special Servicer
shall process all Major Decisions with respect to any Serviced

     -458-


     


    

 


Notwithstanding anything
herein to the contrary, with respect to any Servicing Shift Mortgage Loan, the Loan-Specific Directing Certificateholder shall,

After the occurrence
and during the continuance of a Control Termination Event but prior to the occurrence of a Consultation Termination Event, the
Special Servicer shall consult with the Directing Holder in connection with any Major Decision not relating to any Non-Serviced
Mortgage Loan or Excluded Loan as to such party (and any other actions which otherwise require consultation with the Directing
Certificateholder prior to a Consultation Termination Event hereunder) and the Risk Retention Consultation Party (only with respect
to a Specially Serviced Loan and consider alternative actions recommended by the Directing Certificateholder or the Risk Retention
Consultation Party, in respect thereof. In the event the Special Servicer receives no response from the Directing Holder or the
Risk Retention Consultation Party within 10 Business Days following its written request for input on any required consultation,
the Special Servicer shall not be obligated to consult with the Directing Holder or the Risk Retention Consultation Party, respectively,
on the specific matter; provided, however, that the failure of the Directing Holder or the Risk Retention Consultation
Party to respond shall not relieve the Special Servicer from consulting with the Directing Holder or the Risk Retention Consultation
Party on any future matters with respect to the related Mortgage Loan (other than a Non-Serviced Mortgage Loan or any applicable
Excluded Loan as to the Directing Certificateholder or the holder of the majority of the Controlling Class) or Serviced Whole Loan.


 


Notwithstanding anything
herein to the contrary, no such advice, direction or objection by, from or on the part of the Directing Certificateholder, Operating
Advisor or Risk Retention Consultation Party contemplated in the preceding paragraphs of this Section 6.08(a), may require
or cause the Master Servicer or Special Servicer to violate any provision of any Mortgage Loan or related Intercreditor Agreement,
applicable law, this Agreement, or the REMIC Provisions (and, with respect to a Serviced Whole Loan, subject to the rights of the
holders of the related Companion Loan), including without limitation the obligation of the Master Servicer and the Special Servicer
to act in accordance with the Servicing Standard, or expose the Master Servicer, the Special Servicer, the Certificate Administrator,
the Operating Advisor, the Asset Representations Reviewer, the Trust or the Trustee to liability, or materially expand the scope
of the responsibilities of the Master Servicer or the Special Servicer, as applicable, hereunder or cause the Master Servicer or
the Special Servicer, as applicable, to act, or fail to act, in a manner which in the reasonable judgment of the Master Servicer
or the Special Servicer, as the case may be, is not in the best interests of the Certificateholders. In the event the Special Servicer
or the Master Servicer, as applicable, determines that a refusal to consent by the Directing Certificateholder or any advice from
the Operating Advisor, the Directing Certificateholder or the Risk Retention Consultation Party, would cause the Special Servicer
or Master Servicer, as applicable, to violate the terms of any Mortgage Loan, applicable law or this Agreement, including without
limitation, the Servicing Standard, the Special Servicer or the Master Servicer, as applicable, shall disregard such refusal to
consent or advise and notify the Operating Advisor, the Directing Certificateholder or the Risk Retention Consultation Party,

respectively,
and the Trustee and the Rating Agencies of its determination, including a reasonably detailed explanation of the basis therefor.
The taking of, or refraining from taking, any action by the Master Servicer or the Special Servicer in accordance with the direction
of or approval of the Directing Certificateholder and the Operating Advisor or the approval of the Risk Retention Consultation
Party that does not violate the terms of any Mortgage Loan, Trust Subordinate Companion Loan, applicable law or the Servicing
Standard or any other provisions of this Agreement, will not result in any liability on the part of the Master Servicer or the
Special Servicer.


 


The Directing Holder
shall have no liability to the Trust or the Certificateholders for any action taken, or for refraining from the taking of any action,
or for errors in judgment; provided, however, that the Directing Holder shall not be protected against any liability
to a Controlling Class Certificateholder that would otherwise be imposed by reason of willful misconduct, bad faith or negligence
in the performance of duties owed to the Controlling Class Certificateholders or by reason of reckless disregard of obligations
or duties owed to the Controlling Class Certificateholders. By its acceptance of a Certificate, each Certificateholder acknowledges
and agrees that the Directing Holder may take actions that favor the interests of one or more Classes of Certificates including

of the Holders of the Controlling Class, and that the Directing Holder shall have no liability whatsoever for having so acted,
and no Certificateholder may take any action whatsoever against the Directing Holder or any director, officer, employee, agent
or principal thereof for having so acted.


 


The Risk Retention Consultation
Party shall have no liability to the Trust or the Certificateholders for any action taken, or for refraining from the taking of
any action, or for errors in judgment; provided, however, that the Risk Retention Consultation Party shall not be
protected against any liability to a Holder of an VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest,
as applicable, that would otherwise be imposed by reason of willful misconduct, bad faith or gross negligence in the performance
of duties owed to the Holders of the VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest, as applicable,

that the Risk Retention Consultation Party may take actions that favor the interests of one or more Classes of the Certificates
including the Holders of an VRR Interest, Y&L Towers VRR Interest or Standard Highline VRR Interest, as applicable, over other
Classes of the Certificates, and that the Risk Retention Consultation Party may have special relationships and interests that conflict
with those of Holders of some Classes of the Certificates, that the Risk Retention Consultation Party may act solely in the interests

and no Certificateholder may take any action whatsoever against the Risk Retention Consultation Party or any director, officer,
employee, agent or principal thereof for having so acted.


 


Any Non-Serviced Whole
Loan Controlling Holder, with respect to a Non-Serviced Whole Loan, shall have no liability to the Trust or the Certificateholders
for any action taken, or for refraining from the taking of any action, or for errors in judgment. By its acceptance of a Certificate,
each Certificateholder acknowledges and agrees that any such Non-Serviced Whole Loan Controlling Holder, with respect to the related
Non-Serviced Whole Loan, may take actions that favor the interests of one or more classes of the certificates issued under the
related Non-Serviced PSA including the Holders of the controlling class under such Non-Serviced PSA over other Classes of the Certificates,
and that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, may have special relationships
and interests that conflict with those of Holders of some Classes of the Certificates, that such Non-Serviced Whole Loan Controlling
Holder, with respect to such Non-Serviced Whole Loan, may act solely in the interests of the Holders of the controlling class under

and that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, shall have no liability
whatsoever for having so acted, and no Certificateholder may take any action whatsoever against such Non-Serviced Whole Loan Controlling
Holder, with respect to such Non-Serviced Whole Loan, or any director, officer, employee, agent or principal thereof for having
so acted.


 


(b)         Notwithstanding
anything to the contrary contained herein (i) after the occurrence and during the continuance of a Control Termination Event (and
at any time with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing
Certificateholder, the Holder of the majority of the Controlling Class), the Directing Holder shall have no right to consent to
or direct any action taken or not taken by any party to this Agreement; (ii) after the occurrence and during the continuance of
a Control Termination Event but prior to the occurrence and continuance of a Consultation Termination Event, the Directing Holder
shall remain entitled to receive any notices, reports or information to which it is entitled pursuant to this Agreement, and the
Special Servicer and any other applicable party shall consult with the Directing Holder (other than with respect to any Excluded
Loan as to such party) to the extent set forth herein in connection with any action to be taken or refrained from taking; and (iii)
after the occurrence and continuance of a Consultation Termination Event, the Directing Holder (at any time with respect to any
Excluded Loan as to either such party) shall have no direction, consultation or consent rights hereunder and no right to receive
any notices, reports or information (other than notices, reports or information required to be delivered to all Certificateholders)
or any other rights as Directing Holder.


 


For the avoidance of
doubt, with respect to any Specially Serviced Loan, the Risk Retention Consultation Party shall at all times remain entitled to
receive any notices, reports or


 






     -461-


     


    

 


information
to which it is entitled pursuant to this Agreement, and the Special Servicer and any other applicable party shall consult with
the Risk Retention Consultation Party (other than with respect to any Excluded Loan as to such party) to the extent set forth
herein in connection with any action to be taken or refrained from taking.


 


(c)         Prior
to the occurrence and continuance of an Operating Advisor Consultation Event, the Special Servicer shall provide each Major Decision
Reporting Package to the Operating Advisor promptly after the Special Servicer receives the Directing Holder’s approval or
deemed approval of such Major Decision Reporting Package; provided, however, that with respect to any non-Specially
Serviced Loan no Major Decision Reporting Package shall be required to be delivered prior to the occurrence and continuance of
an Operating Advisor Consultation Event. During the continuance of an Operating Advisor Consultation Event (whether or not a Control
Termination Event is continuing), the Special Servicer will be required to provide each Major Decision Reporting Package to the
Operating Advisor simultaneously with the Special Servicer’s written request for the Operating Advisor’s input regarding
the related Major Decision (which written request and Major Decision Reporting Package may be delivered in one notice), as set
forth under Section 6.08. With respect to any particular Major Decision and/or related Major Decision Reporting Package
or any Asset Status Report required to be delivered by the Master Servicer or the Special Servicer to the Operating Advisor, the
Master Servicer or the Special Servicer, as applicable, shall make available to the Operating Advisor a servicing officer with
relevant knowledge regarding the Mortgage Loan and such Major Decision and/or Asset Status Report in order to address reasonable
questions that the Operating Advisor may have relating to, among other things, such Major Decision and/or Asset Status Report.


 


In addition, if an Operating
Advisor Consultation Event has occurred and is continuing, the Special Servicer will also be required to consult with the Operating
Advisor in connection with any proposed Major Decision (and any other actions which otherwise require consultation with the Operating
Advisor) and consider alternative actions recommended by the Operating Advisor, in respect thereof, provided that such consultation
is on a non-binding basis. In the event that the Special Servicer receives no response from the Operating Advisor within ten (10)
days following the later of (i) its written request for input (which request is required to include the related Major Decision
Reporting Package) on any required consultation and (ii) delivery of all such additional information reasonably requested by the
Operating Advisor that is in the possession of the Special Servicer related to the subject matter of such consultation, the Special
Servicer shall not be obligated to consult with the Operating Advisor on the specific matter; provided, however,
that the failure of the Operating Advisor to respond on any specific matters shall not relieve the Special Servicer from its obligation
to consult with the Operating Advisor on any future matter with respect to the applicable Mortgage Loan or Trust Subordinate Companion
Loan or any other Mortgage Loan. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan (regardless
of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer shall consult with the
Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed Major Decisions that
it is processing and consider alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with
the procedures set forth in this Section 6.08 for consulting with the Operating Advisor.


 






     -462-


     


    

 


In connection with the
Directing Certificateholder’s or Operating Advisor’s right to consent or consult with respect to a Major Decision,
as applicable, if the Special Servicer determines that action is necessary to protect the related Mortgaged Property or the interests
of the Certificateholders from potential harm if such action is not taken, or if a failure to take any such action at such time
would be inconsistent with Accepted Servicing Practices, the Special Servicer may take actions with respect to the related Mortgaged
Property before the expiration of the applicable period for the Operating Advisor or Directing Certificateholder to respond as
described in this section, if the Special Servicer reasonably determines in accordance with Accepted Servicing Practices that failure
to take such actions before the expiration of such period would materially adversely affect the interest of the Certificateholders,
and the Special Servicer has made a reasonable effort to contact the Operating Advisor or the Directing Certificateholder, as applicable.


 


In addition, (i) for
so long as no Consultation Termination Event is continuing, with respect to any Specially Serviced Loan (other than any Non-Serviced
Mortgage Loan or any applicable Excluded Loan) and (ii) during the continuance of a Consultation Termination Event, with respect
to any Mortgage Loan (other than any Non-Serviced Mortgage Loan or applicable Excluded Loan), the Special Servicer will also be
required to consult with the Risk Retention Consultation Party in connection with any Major Decision that it is processing (and
such other matters that are subject to consultation rights of the Risk Retention Consultation Party pursuant to this Agreement)
and to consider alternative actions recommended by the Risk Retention Consultation Party in respect of such Major Decision; provided
that such consultation is on a non-binding basis. In the event the Master Servicer or the Special Servicer, as applicable, receives
no response from the Risk Retention Consultation Party within 10 days following the later of (i) the Special Servicer’s,
written request for input (which request is required to include the related Major Decision Reporting Package) on any required consultation
and (ii) delivery of all such additional information reasonably requested by the Risk Retention Consultation Party and reasonably
available to the Special Servicer related to the subject matter of such consultation, the Master Servicer or the Special Servicer,
as applicable, will not be obligated to consult with the Risk Retention Consultation Party on the specific matter; provided,
however, that the failure of the Risk Retention Consultation Party to respond shall not relieve the Master Servicer or the
Special Servicer, as applicable, using reasonable efforts to consult with the Risk Retention Consultation Party on any future matters
with respect to the applicable Mortgage Loan or Serviced Whole Loan or any other Mortgage Loan.


 


After the occurrence
and during the continuance of a Consultation Termination Event, the Directing Certificateholder shall have no consultation or consent
rights hereunder and shall have no right to receive any notices, reports or information (other than notices, reports or information
required to be delivered to all Certificateholders) or any other rights as Directing Certificateholder. However, the Directing
Certificateholder shall maintain the right to exercise its Voting Rights for the same purposes as any other Certificateholder.


 


Section 6.09      Knowledge
of Wells Fargo Bank, National Association. Except as otherwise expressly set forth in this Agreement, Wells Fargo Bank, National
Association acting in any particular capacity hereunder will not be deemed to be imputed with knowledge of (a) Wells Fargo Bank,
National Association, acting in a capacity that is unrelated to the transactions contemplated by this Agreement, or (b) Wells
Fargo Bank, National Association, acting in any


 






     -463-


     


    

 


other
capacity hereunder, except, in the case of either clause (a) or clause (b), where some or all of the obligations
performed in such capacities are performed by one or more employees within the same group or division of Wells Fargo Bank, National
Association, or where the groups or divisions responsible for performing the obligations in such capacities have one or more of
the same Responsible Officers or Servicing Officers, as applicable; provided that the knowledge of employees performing
special servicing functions shall not be imputed to employees performing master servicing functions and vice versa.

and Section 7.02 and to which the Master Servicer can sell its rights to service the Mortgage Loans and the Trust Subordinate
Companion Loans under this Agreement. During such forty-five (45) day period the Master Servicer may continue to serve as Master
Servicer hereunder. In the event that the Master Servicer is unable, within such forty-five (45) day period, to cause a qualified
successor master servicer to assume the duties of the Master Servicer hereunder, then and in such event, the Trustee shall assume
the obligations of the Master Servicer hereunder.


 


Notwithstanding Section
7.01(a)(viii), if any Servicer Termination Event on the part of the Special Servicer shall occur and be continuing that affects
the Holder of a Serviced Pari Passu Companion Loan, then, so long as the Special Servicer is not otherwise terminated, the Holder
of such Serviced Pari Passu Companion Loan or the Other Trustee appointed under the related Other Pooling and Servicing Agreement,
as applicable, shall be entitled to direct the Trustee to terminate the Special Servicer with respect to the related Serviced Pari
Passu Whole Loan. The Special Servicer appointed to replace the Special Servicer with respect to a Serviced Pari Passu Mortgage
Loan cannot at any time be (without the prior written consent of the holder of such Serviced Pari Passu Companion Loan) the person
(or Affiliate thereof) that was terminated at the direction of the holder of the related Serviced Pari Passu Companion Loan. Any
the Special Servicer under this paragraph shall meet the eligibility requirements of Section 7.02 and the eligibility requirements
of the related Other Pooling and Servicing Agreement, and the appointment thereof shall comply with the provisions of Section
7.02. Any appointment of a replacement special servicer in accordance with this paragraph shall be subject to the receipt of
Rating Agency Confirmation and confirmation from the rating agencies that such appointment or replacement will not result in the
downgrade, withdrawal or qualification of the then-current ratings of any class of any related Serviced Companion Loan Securities
(provided that such rating agency confirmation may be considered satisfied in the same manner


 






     -468-


     


    

 


as any
Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25).


 


If any Servicer Termination
Event on the part of the Master Servicer affects only the Y&L Towers Trust Subordinate Companion Loan, the Master Servicer
may not be terminated as the Master Servicer of the Mortgage Pool, but the Y&L Towers Directing Holder, as applicable (prior
to the occurrence and continuance of a Y&L Towers Trust Subordinate Control Termination Event) will be entitled to direct the
Master Servicer to appoint a sub-servicer solely with respect to the related Whole Loan (or if the Yorkshire & Lexington Towers
Whole Loan is currently being sub-serviced, to replace the current sub-servicer, but only if such sub-servicer is in default under
the related sub-servicing agreement).


 


If any Servicer Termination
Event on the part of the Master Servicer affects only the Standard Highline Trust Subordinate Companion Loan, the Master Servicer
may not be terminated as the Master Servicer of the Mortgage Pool, but the Standard Highline Directing Holder (prior to the occurrence
and continuance of a Standard Highline Non-Trust Junior Subordinate Control Termination Event, a Standard Highline Non-Trust Senior
Subordinate Control Termination Event or a Standard Highline Trust Subordinate Control Termination Event, as applicable) will be
entitled to direct the Master Servicer to appoint a sub-servicer solely with respect to The Standard Highline NYC Whole Loan (or
if The Standard Highline NYC Whole Loan is currently being sub-serviced, to replace the current sub-servicer, but only if such
sub-servicer is in default under the related sub-servicing agreement).


 


(d)       Subject
to the right of the Operating Advisor to recommend the termination of the Special Servicer and recommend a Qualified Replacement
Special Servicer and the right of the applicable Certificateholders to approve the replacement of the Special Servicer with such
Qualified Replacement Special Servicer pursuant to this Section 7.01(d), and subject to the rights of the holder of a related
AB Subordinate Companion Loan (other than a Trust Subordinate Companion Loan pursuant to the related Intercreditor Agreement, at
any time prior to the occurrence and continuance of a Control Termination Event and other than with respect to any Excluded Loan
with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder
shall be entitled to terminate the rights (subject to Section 3.11 and Section 6.04) and obligations of the Special
Servicer under this Agreement, with or without cause, upon ten (10) Business Days’ notice to the Special Servicer, the Master
Servicer, the Certificate Administrator, the Trustee and the Operating Advisor; such termination to be effective upon the appointment
of a successor special servicer meeting the requirements of this Section 7.01(d), provided that, with respect to
a Servicing Shift Whole Loan, the ten (10) Business Days’ notice set forth in this Section 7.01(d) shall not apply
to the related Loan-Specific Directing Certificateholder’s right to terminate the Special Servicer’s rights and obligations
under this Agreement without cause with respect to such Servicing Shift Whole Loan pursuant to the terms of the related Co-Lender
Agreement. Upon a termination of the Special Servicer, the Directing Certificateholder (other than with respect to any Excluded
Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class) shall designate a
successor special servicer; provided, however, that (i) such successor will meet the requirements set forth in Section
7.02, (ii) each Rating Agency delivers Rating Agency Confirmation and, in the case of any class of any Serviced Companion Loan
Securities the applicable rating agencies deliver a confirmation that such action will not


 






     -469-


     


    

 


result
in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25) and (iii) no replacement of the Special Servicer shall be effective until the Certificate
Administrator shall have filed any required Form 8-K pursuant to Section 11.07 hereof and any other Form 8-K filings have
been completed with respect to any related Companion Loan.


 


After the occurrence
and during the continuance of a Control Termination Event that relates to any Mortgage Loan (but for so long as no Control Termination
Event is continuing with respect to the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, as
applicable) or Serviced Whole Loan, upon (a) the written direction of (a) Holders of Pooled Principal Balance Certificates evidencing
not less than 25% of the Pooled Voting Rights (taking into account the application of any Appraisal Reduction Amounts to notionally
reduce the Certificate Balances pursuant to Section 4.05 hereof) of the Pooled Principal Balance Certificates requesting
a vote to replace the Special Servicer (other than with respect to the Yorkshire & Lexington Towers Whole Loan or The Standard
Highline NYC Whole Loan, as applicable) with a new special servicer designated in such written direction, (b) payment by such Holders
to the Certificate Administrator of the reasonable fees and expenses (including any legal fees and any Rating Agency fees and expenses)
to be incurred by the Certificate Administrator in connection with administering such vote and which shall not be additional expenses
of the Trust and (c) delivery by such Holders to the Certificate Administrator and Trustee of Rating Agency Confirmation from each
Rating Agency (which Rating Agency Confirmation shall be obtained at the expense of such Holders), the Certificate Administrator
shall promptly post notice to all Certificateholders of such request on the Certificate Administrator’s Website in accordance
with Section 3.13(b) and concurrently by mail, and conduct the solicitation of votes of all Pooled Certificates in such
regard, which vote shall occur within one hundred eighty (180) days of the posting of such notice. Upon the written direction of
(a) Holders of Pooled Principal Balance Certificates evidencing at least 66-2/3% of a Pooled Certificateholder Quorum or (b) Holders
of Pooled Voting Rights of each Class of Pooled Non-Reduced Certificates evidencing more than 66 2/3% of the Pooled Voting Rights
of each of Class of Pooled Non-Reduced Certificates, the Trustee shall terminate all of the rights and obligations of the Special
Servicer (other than with respect to the Yorkshire & Lexington Towers Whole Loan and The Standard Highline NYC Whole Loan,
as applicable) under this Agreement and appoint the successor special servicer (which must be a Qualified Replacement Special Servicer)
designated by such Pooled Certificateholders.


 


After the occurrence
and during the continuance of a Control Termination Event that relates to any Mortgage Loan (and for so long as a Control Termination
Event is continuing with respect to the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan, as
applicable), upon (a) the written direction of Holders of Principal Balance Certificates evidencing not less than 25% of the Voting
Rights (taking into account the application of any Cumulative Appraisal Reduction Amounts to notionally reduce the Certificate
Balances pursuant to Section 4.05 hereof) of the Principal Balance Certificates requesting a vote to replace such Special
Servicer with a new special servicer designated in such written direction, (b) payment by such Holders to the Certificate Administrator
of the reasonable fees and expenses (including any legal fees and any Rating Agency fees and expenses) to be incurred by the


 






     -470-


     


    

 


Certificate
Administrator in connection with administering such vote and which will not be additional expenses of the Trust and (c)
delivery by such Holders to the Certificate Administrator and Trustee of Rating Agency Confirmation from each Rating Agency
(which Rating Agency Confirmation shall be obtained at the expense of such Holders), the Certificate Administrator shall
promptly post notice to all Certificateholders of such request on the Certificate Administrator’s Website in accordance
with Section 3.13(b) and concurrently by mail, and conduct the solicitation of votes of all Certificates in such
regard, which requisite affirmative votes shall be received within one hundred eighty (180) days of the posting of such
notice. Upon the written direction of (a) Holders of Principal Balance Certificates evidencing at least 66 2/3% of a
Certificateholder Quorum or (b) Holders of Non-Reduced Certificates evidencing more than 66 2/3% of the aggregate Voting
Rights of each Class of Non-Reduced Certificates, the Trustee shall terminate all of the rights and obligations of such
Special Servicer under this Agreement and appoint the successor special servicer (which must be a Qualified Replacement
Special Servicer) designated by such Certificateholders.


 


The Certificate Administrator
shall include on each Distribution Date Statement a statement that each Certificateholder may (i) access such notices via the Certificate
Administrator’s Website and (ii) register to receive electronic mail notifications when such notices are posted thereon.
Notwithstanding the foregoing, the Certificateholders’ direction to replace the Special Servicer will not apply to a Serviced
AB Whole Loan unless, with respect to a Pooled Serviced Whole Loan, an AB Control Appraisal Period is continuing, with respect
to the Yorkshire & Lexington Towers Whole Loan, a Y&L Towers Control Termination Event is continuing and with respect to
The Standard Highline NYC Whole Loan, a Standard Highline Control Termination Event is continuing. With respect to The Standard
Highline NYC Whole Loan, the Standard Highline Non-Trust Junior Subordinate Companion Loan, will have the right, prior to the occurrence
and continuance of a Standard Highline Non-Trust Junior Subordinate Companion Loan Control Appraisal Period, to replace the Special
Servicer with respect to The Standard Highline NYC Whole Loan. After a Standard Highline Non-Trust Junior Subordinate Companion
Loan Control Appraisal Period and prior to a Standard Highline Non-Trust Senior Subordinate Companion Loan Control Appraisal Period,
the Standard Highline Non-Trust Senior Subordinate Companion Loan will have the right to replace the Special Servicer with respect
to The Standard Highline NYC Whole Loan. The Standard Highline Trust Subordinate Companion Loan will have the right, after the
occurrence and continuance of a Standard Highline Non-Trust Senior Subordinate Companion Loan Control Appraisal Period and prior
to the occurrence and continuance of a Standard Highline Trust Subordinate Companion Loan Control Termination Event, to replace
the Special Servicer solely with respect to The Standard Highline NYC Whole Loan.


 


The parties hereto acknowledge
that, notwithstanding anything to the contrary contained in this section, in accordance with the related Intercreditor Agreement,
if a servicer termination event on the part of a Non-Serviced Special Servicer under a Non-Serviced PSA remains unremedied and
affects the holder of the related Non-Serviced Mortgage Loan, and the related Non-Serviced Special Servicer has not otherwise been
terminated, the holder of the related Non-Serviced Mortgage Loan (or the Trustee (or, prior to a Control Termination Event, the
Trustee, acting at the direction of the Directing Certificateholder)) will be entitled to direct the related Non-Serviced Trustee
to terminate the related Non-Serviced Special Servicer solely with respect to the related Non-Serviced Whole Loan. The appointment
(or replacement) of a


 






     -471-


     


    

 


special
servicer with respect to a Non-Serviced Whole Loan, as applicable, will in any event be subject to Rating Agency Confirmation
from each Rating Agency. A replacement special servicer will be selected by the related Non-Serviced Trustee or, prior to a control
termination event (or similarly defined term) under the related Non-Serviced PSA, by the related Non-Serviced Whole Loan Controlling
Holder; provided, however, that any successor special servicer appointed to replace the special servicer with respect
to such Non-Serviced Whole Loan cannot at any time be the Person (or an Affiliate thereof) that was terminated at the direction
of the holder of such Non-Serviced Mortgage Loan, without the prior written consent of the Directing Certificateholder.


 


If at any time the Operating
Advisor determines, in its sole discretion exercised in good faith, that (i) the Special Servicer is not performing its duties
as required hereunder or is otherwise not acting in accordance with the Servicing Standard, and (ii) the replacement of the Special
Servicer would be in the best interest of the Certificateholders as a collective whole, then the Operating Advisor shall deliver
to the Trustee and the Certificate Administrator, with a copy to the Special Servicer, a written report in the form of Exhibit
W attached hereto (which form may be modified or supplemented from time to time to cure any ambiguity or error or to incorporate
any additional information, subject to compliance of such form with the terms and provisions of this Agreement; provided,
further, that in no event shall the information or any other content included in such written report contravene any provision
of this Agreement) detailing the reasons supporting its recommendation (provided that the Operating Advisor will not be
permitted to recommend the replacement of the Special Servicer for any Whole Loan so long as the holder of the related Companion
Loan is the Directing Holder under the related Intercreditor Agreement) (along with relevant information justifying its recommendation)
and recommending a suggested replacement special servicer, which shall be a Qualified Replacement Special Servicer. In such event,
the Certificate Administrator shall promptly post notice to all applicable Certificateholders of such recommendation and the related
report on the Certificate Administrator’s Website in accordance with Section 3.13(b), and by mail conduct the solicitation
of votes of all applicable Certificates in such regard. Upon (i) the affirmative vote of Voting Rights evidencing at least a majority
of a Quorum (which, this purpose is the Holders that (i) evidence at least 20% of the Voting Rights (taking into account the application
of any Appraisal Reduction Amounts to notionally reduce the respective Certificate Balances) of all Principal Balance Certificates
on an aggregate basis, and (B) consist of at least three (3) Certificateholders, or the Certificate Owners that are not Risk Retention
Affiliated with each other) and (ii) receipt of Rating Agency Confirmation from each Rating Agency with respect to the termination
of the Special Servicer and the appointment of a successor special servicer recommended by the Operating Advisor following satisfaction
of the foregoing clause (i), the Trustee (upon receipt of written confirmation from the Certificate Administrator, if the
Certificate Administrator and the Trustee are different entities) shall (i) terminate all of the rights and obligations of the
Special Servicer under this Agreement and appoint such successor Special Servicer and (ii) promptly notify such outgoing Special
Servicer of the effective date of such termination. The reasonable out-of-pocket costs and expenses (including reasonable legal
fees and expenses of outside counsel) associated with obtaining such Rating Agency Confirmations and administering such vote(s)
and the Operating Advisor’s identification of a Qualified Replacement Special Servicer shall be an additional expense of
the Trust. In the event that the Trustee does not receive the affirmative vote of at least a majority of the quorum described in
clause (i) of the preceding sentence within 180 days of the posting of the notice to the Certificate Administrator’s
Website,


 






     -472-


     


    

 


then
the Trustee shall have no obligation to remove the Special Servicer. Prior to the appointment of any replacement special servicer,
such replacement special servicer shall have agreed to succeed to the obligations of the Special Servicer under this Agreement
and to act as the Special Servicer’s successor hereunder. In the event the Special Servicer is terminated pursuant to this
Section 7.01(d), the Directing Holder may not subsequently reappoint such terminated Special Servicer or any Risk Retention
Affiliate thereof.


 


No penalty or fee shall
be payable to the terminated Special Servicer with respect to any termination pursuant to this Section 7.01(d). All costs
of any such termination made by the Directing Certificateholder without cause shall be paid by the Holders of the Controlling Class.


 


For the avoidance of
doubt, the indemnification of the Operating Advisor in Section 6.04 shall include, subject to the limitations set forth
in Section 6.04, any action or claim arising from, or relating to, the Operating Advisor’s determination under this
Section 7.01(d) (regarding removal of the Special Servicer), or the result of the vote of the Pooled Certificateholders
or Loan-Specific Certificateholders, as applicable (regarding removal of the Special Servicer).


 


(e)         The
Master Servicer and the Special Servicer shall, as the case may be, from time to time, take all such reasonable actions as are
required by it in accordance with the related Servicing Standard in order to prevent the Certificates from being placed on “watch”
status or downgraded due to servicing or special servicing, as applicable, concerns by any Rating Agency. In no event shall the
remedy for a breach of the foregoing covenant extend beyond termination pursuant to Section 7.01(a)(viii) and Section
7.01(a)(ix) and the resulting operation of Section 7.01(a)(viii) and (c). The operation of this subsection
(e) shall not be construed to limit the effect of Section 7.01(a)(viii) and Section 7.01(a)(ix).


 


(f)          Notwithstanding
the foregoing, (1) if any Servicer Termination Event on the part of the Master Servicer affects a Serviced Companion Loan, any
related Serviced Companion Noteholder or the rating on any class of certificates backed, wholly or partially, by any Serviced Companion
Loan Securities, and if the Master Servicer is not otherwise terminated, or (2) if a Servicer Termination Event on the part of
the Master Servicer affects only a Serviced Companion Loan, any related Serviced Companion Noteholder or the rating on any class
of certificates backed, wholly or partially, by any Serviced Companion Loan Securities, then the Master Servicer may not be terminated
by or at the direction of such Serviced Companion Noteholder or the holders of any certificates backed, wholly or partially, by
such Serviced Companion Loan, but upon the written direction of such Serviced Companion Noteholder, the Master Servicer shall be
required to appoint a sub-servicer that will be responsible for servicing the related Serviced Whole Loan.


 


(g)         Notwithstanding
anything to the contrary contained in this Section 7.01, with respect to any Excluded Special Servicer Loan, if any, the
related Special Servicer shall resign as Special Servicer of that Excluded Special Servicer Loan. Prior to the occurrence and continuance
of a Control Termination Event, if the applicable Excluded Special Servicer Loan is not also an Excluded Loan as to the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the
Directing Holder shall


 






     -473-


     


    

 


select
an Excluded Special Servicer, as successor to the resigning Special Servicer, for the related Excluded Special Servicer Loan in
accordance with this Agreement. After the occurrence and during the continuance of a Control Termination Event or if the Directing
Certificateholder or the majority Controlling Class Certificateholder on its behalf fails to make the selection contemplated by
the prior sentence within ten (10) Business Days or if at any time the applicable Excluded Special Servicer Loan is also an Excluded
Loan as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of
the Controlling Class, the resigning Special Servicer shall use reasonable efforts to select the related Excluded Special Servicer.
The Special Servicer shall not have any liability with respect to the actions or inactions of the applicable Excluded Special
Servicer or with respect to the identity of the applicable Excluded Special Servicer so long as, on the date of the appointment,
such appointment of such Excluded Special Servicer meets the criteria of this Agreement. It shall be a condition to any such appointment
that (i) the Rating Agencies confirm that the appointment would not result in a qualification, downgrade or withdrawal of any
of their then-current ratings of the Certificates and each NRSRO hired to provide ratings with respect to any Serviced Companion
Loan Securities makes the equivalent confirmation, (ii) the related Excluded Special Servicer is a Qualified Replacement Special
Servicer and (iii) the related Excluded Special Servicer delivers to the Depositor and the Certificate Administrator and any applicable
Other Depositor and Other Certificate Administrator, the information, if any, required under Item 6.02 of Form 8-K pursuant to
the Exchange Act regarding itself in its role as Excluded Special Servicer.


 


If at any time the Special
Servicer is no longer a Borrower Party (including, without limitation, as a result of the related Mortgaged Property becoming an
REO Property) with respect to an Excluded Special Servicer Loan, (1) the related Excluded Special Servicer shall resign, (2) the
related Mortgage Loan or Serviced Whole Loan shall no longer be an Excluded Special Servicer Loan, (3) the Special Servicer shall
become the Special Servicer again for such related Mortgage Loan or Serviced Whole Loan and (4) the Special Servicer shall be entitled
to all special servicing compensation with respect to such Mortgage Loan or Serviced Whole Loan earned during such time on and
after such Mortgage Loan or Serviced Whole Loan is no longer an Excluded Special Servicer Loan; provided, however,
that other than with respect to an Excluded Loan, the related Excluded Special Servicer shall not be required to resign if the
Directing Holder determines that such Excluded Special Servicer may continue to serve as special servicer for the applicable Excluded
Special Servicer Loan.


 


The applicable Excluded
Special Servicer shall perform all of the obligations of the Special Servicer for the related Excluded Special Servicer Loan and
shall be entitled to all special servicing compensation with respect to such Excluded Special Servicer Loan earned during such
time as the related Mortgage Loan or Serviced Whole Loan is an Excluded Special Servicer Loan (provided that the Special
Servicer shall remain entitled to all other special servicing compensation with respect all Mortgage Loans and Serviced Whole Loans
that are not Excluded Special Servicer Loans during such time).


 


If a Servicing Officer
of the Master Servicer, a related Excluded Special Servicer, or the Special Servicer, as applicable, has actual knowledge that
a Mortgage Loan is no longer an Excluded Loan, an Excluded Controlling Class Loan or an Excluded Special Servicer Loan, as applicable,
the Master Servicer, the related Excluded Special Servicer or the Special Servicer, as


 






     -474-


     


    

 


applicable,
shall provide prompt written notice thereof to each of the other parties to this Agreement.


 


Section 7.02     Trustee
to Act; Appointment of Successor. On and after the time the Master Servicer or the Special Servicer, as the case may be, either
resigns pursuant to subsection (a) of the first sentence of Section 6.05 or receives a notice of termination for
cause pursuant to Section 7.01(a)(viii), and provided that no acceptable successor has been appointed within the
time period specified in Section 7.01(c), the Trustee shall be the successor to such party, until such successor to the
Master Servicer or the Special Servicer, as applicable, is appointed as provided in this Section 7.02 or by the Directing
Holder as provided in Section 7.01(d), as applicable, in all respects in its capacity as Master Servicer or the Special
Servicer, as applicable, under this Agreement and the transactions set forth or provided for herein and shall be subject to, and
have the benefit of, all of the rights, (subject to Section 3.11 and Section 6.04) benefits, responsibilities, duties,
liabilities and limitations on liability relating thereto and that arise thereafter placed on or for the benefit of the Master
Servicer or the Special Servicer, as applicable, by the terms and provisions hereof; provided, however, that any
failure to perform such duties or responsibilities caused by the terminated party’s failure under Section 7.01 to
provide information or moneys required hereunder shall not be considered a default by such successor hereunder. The appointment
of a successor master servicer shall not affect any liability of the predecessor Master Servicer which may have arisen prior to
its termination as Master Servicer, and the appointment of a successor special servicer shall not affect any liability of the
predecessor Special Servicer which may have arisen prior to its termination as Special Servicer. The Trustee in its capacity as
successor to the Master Servicer or the Special Servicer, as the case may be, shall not be liable for any of the representations
and warranties of the Master Servicer or the Special Servicer, respectively, herein or in any related document or agreement, for
any acts or omissions of the predecessor master servicer or special servicer or for any losses incurred by the predecessor Master
Servicer pursuant to Section 3.06 hereunder, nor shall the Trustee be required to purchase any Mortgage Loan or Trust Subordinate
Companion Loan hereunder solely as a result of its obligations as successor master servicer or special servicer, as the case may
be. Subject to Section 3.11, as compensation therefor, the Trustee as successor master servicer shall be entitled to the
Servicing Fees and all fees relating to the Mortgage Loans, the Companion Loans that the Master Servicer would have been entitled
to if the Master Servicer had continued to act hereunder, including but not limited to any income or other benefit from any Permitted
Investment pursuant to Section 3.06, and subject to Section 3.11, and the Trustee as successor to the Special Servicer
shall be entitled to the Special Servicing Fees to which the Special Servicer would have been entitled if the Special Servicer
had continued to act hereunder. Should the Trustee succeed to the capacity of the Master Servicer or the Special Servicer, as
the case may be, the Trustee shall be afforded the same standard of care and liability as the Master Servicer or the Special Servicer,
as applicable, hereunder notwithstanding anything in Section 8.01 to the contrary, but only with respect to actions taken
by it in its role as successor master servicer or successor special servicer, as the case may be, and not with respect to its
role as Trustee hereunder. Notwithstanding the above, the Trustee may, if it shall be unwilling to act as successor to the Master
Servicer or the Special Servicer, as applicable, or shall, if it is unable to so act, or if the Trustee is not approved as a servicer
by each Rating Agency, or if the Directing Holder ((i) prior to the occurrence and continuance of a Control Termination Event
and (ii) other than with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the
Directing Certificateholder, the Holder of


 






     -475-


     


    

 


the
majority of the Controlling Class) or the Holders of Certificates entitled to at least (a) 25% of the Voting Rights in the
case of the Master Servicer, (b) 25% of the Pooled Voting Rights in the case of the Special Servicer (other than with respect
to the Yorkshire & Lexington Towers Whole Loan or The Standard Highline NYC Whole Loan), (c) 25% of the Y&L Towers
Voting Rights in the case of the Special Servicer with respect to the Yorkshire & Lexington Towers Whole Loan or (d) 25%
of the Standard Highline Voting Rights in the case of the Special Servicer with respect to The Standard Highline NYC Whole
Loan so request in writing to the Trustee, promptly appoint, or petition a court of competent jurisdiction to appoint, any
established mortgage loan servicing institution or other entity which meets the criteria set forth in Section 6.05 and
otherwise herein, as the successor to the Master Servicer or the Special Servicer, as applicable, hereunder in the assumption
of all or any part of the responsibilities, duties or liabilities of the Master Servicer or the Special Servicer hereunder.
No appointment of a successor to the Master Servicer or the Special Servicer hereunder shall be effective until (i) the
assumption in writing by the successor to the Master Servicer or the Special Servicer of all its responsibilities, duties and
liabilities hereunder that arise thereafter, (ii) upon receipt of Rating Agency Confirmation from each Rating Agency and
confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency
confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied
with respect to the Certificates pursuant to Section 3.25), (iii) which appointment has been approved (prior to the
occurrence and continuance of a Control Termination Event) by the Directing Holder, such approval not to be unreasonably
withheld and (iv) the Certificate Administrator shall have filed any required Form 8-K pursuant to Section 11.07 and
any other Form 8-K filings have been completed with respect to any related Companion Loan. Pending appointment of a successor
to the Master Servicer or the Special Servicer hereunder, unless the Trustee shall be prohibited by law from so acting, the
Trustee shall act in such capacity as herein above provided. In connection with such appointment and assumption of a
successor to the Master Servicer or the Special Servicer as described herein, the Trustee may make such arrangements for the
compensation of such successor out of payments on the Mortgage Loans and the Trust Subordinate Companion Loans as it and such
successor shall agree; provided, however, that no such compensation with respect to a successor master servicer
or successor special servicer, as the case may be, shall be in excess of that permitted the terminated Master Servicer or
Special Servicer, as the case may be, hereunder. The Trustee, the Master Servicer or the Special Servicer (whichever is not
the terminated party) and such successor shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. Any costs and expenses associated with the transfer of the servicing function (other than
with respect to a termination without cause) under this Agreement shall be borne by the predecessor Master Servicer or
Special Servicer, as applicable. If such predecessor Master Servicer or Special Servicer (as the case may be) has not
reimbursed the party requesting such termination or the successor master servicer or special servicer for such expenses
within 90 days after the presentation of reasonable documentation, such expense shall be reimbursed by the Trust; provided
that the terminated Master Servicer or Special Servicer shall not thereby be relieved of its liability for such expenses. If
and to the extent that the terminated Master Servicer or Special Servicer has not reimbursed such costs and expenses, the
party requesting such termination shall have an affirmative obligation to take all reasonable actions to collect such
expenses on behalf of the Trust. In the event of a termination


 






     -476-


     


    

 


without cause, such costs and
expenses shall be borne by the party requesting such termination, or as otherwise set forth herein; provided that the Certificate
Administrator and the Trustee shall not bear any such costs and expenses. For the avoidance of doubt, if the Trustee is terminating
the Master Servicer or Special Servicer in accordance with this Agreement at the direction of any party or parties permitted to
direct the Trustee to so terminate the Master Servicer or the Special Servicer pursuant to this Agreement, the Trustee shall not
have any liability for such expenses pursuant to this paragraph.


 


Section 7.03     Notification
to Certificateholders. (a) Upon any resignation of the Master Servicer or the Special Servicer pursuant to Section 6.05,
any termination of the Master Servicer or the Special Servicer pursuant to Section 7.01 or any appointment of a successor
to the Master Servicer or the Special Servicer pursuant to Section 7.02, the Certificate Administrator shall give prompt
written notice thereof to Certificateholders at their respective addresses appearing in the Certificate Register.


 


(b)         Not
later than the later of (i) sixty (60) days after the occurrence of any event which constitutes or, with notice or lapse of time
or both, would constitute a Servicer Termination Event and (ii) five (5) days after the Certificate Administrator would be deemed
to have notice of the occurrence of such an event in accordance with Section 8.02(vii), the Certificate Administrator shall
transmit by mail to the Depositor and all Certificateholders (and, if a Serviced Whole Loan is affected, the related Serviced Companion
Noteholder) notice of such occurrence, unless such default shall have been cured.


 


Section 7.04     Waiver
of Servicer Termination Events. A Servicer Termination Event may be waived by the Certificateholders evidencing not less than
(a) 66-2/3% of the Voting Rights in the case of the Master Servicer, (b) 66-2/3% of the Pooled Voting Rights in the case of the
Special Servicer (other than with respect to the Yorkshire & Lexington Towers Whole Loan and The Standard Highline NYC Whole

to The Standard Highline NYC Whole Loan, within twenty (20) days of the receipt of notice from the Certificate Administrator of
the occurrence of such Servicer Termination Event; provided, however, that (1) a Servicer Termination Event under
clause (i) or (ii) of Section 7.01(a) may be waived only by all of the Certificateholders of the affected
Classes and (2) a Servicer Termination Event under clause (iii) or (ix) of Section 7.01(a) relating to Exchange
Act reporting may be waived only with the consent of the Depositor, together with (in the case of each of clauses (1) and
(2) of this sentence) the consent of each Serviced Companion Noteholder, if any, that is affected by such Servicer Termination
Event. Upon any such waiver of a Servicer Termination Event, such Servicer Termination Event shall cease to exist and shall be
deemed to have been remedied for every purpose hereunder. Upon any such waiver of a Servicer Termination Event by Certificateholders,
the Trustee and the Certificate Administrator shall be entitled to recover all costs and expenses incurred by it in connection
with enforcement action taken with respect to such Servicer Termination Event prior to such waiver from the Trust. No such waiver
shall extend to any subsequent or other Servicer Termination Event or impair any right consequent thereon except to the extent
expressly so waived. Notwithstanding any other provisions of this Agreement, for purposes of waiving any Servicer Termination
Event pursuant to this Section 7.04, Certificates registered in the name of

the Depositor
or any Affiliate of the Depositor shall be entitled to the same Voting Rights with respect to the matters described above as they
would if any other Person held such Certificates.


 


Section
7.05     Trustee as Maker of Advances. In the event that the Master Servicer fails to fulfill its
obligations hereunder to make any Advances and such failure remains uncured, the Trustee shall perform such obligations (x)
within five (5) Business Days following such failure by the Master Servicer with respect to Servicing Advances resulting in a
Servicer Termination Event under Section 7.01(a)(iii) hereof to the extent a Responsible Officer of the Trustee has
actual knowledge of such failure with respect to such Servicing Advances and (y) by noon, New York City time, on the related
Distribution Date with respect to P&I Advances pursuant to the Certificate Administrator’s notice of failure
pursuant to Section 4.03(a) unless such failure has been cured. With respect to any such Advance made by the Trustee,
the Trustee shall succeed to all of the Master Servicer’s rights with respect to Advances hereunder, including, without
limitation, the Master Servicer’s rights of reimbursement and interest on each Advance at the Reimbursement Rate, and
rights to determine that a proposed Advance is a Nonrecoverable P&I Advance or Servicing Advance, as the case may be,
(without regard to any impairment of any such rights of reimbursement caused by such Master Servicer’s default in its
obligations hereunder); provided, however, that if Advances made by the Trustee and the Master Servicer shall
at any time be outstanding, or any interest on any Advance shall be accrued and unpaid, all amounts available to repay
such Advances and the interest thereon hereunder shall be applied entirely to the Advances outstanding to the Trustee, until
such Advances shall have been repaid in full, together with all interest accrued thereon, prior to reimbursement of the
Master Servicer for such Advances. The Trustee shall be entitled to conclusively rely on any notice given with respect to a
Nonrecoverable Advance hereunder.

(c)         No
provision of this Agreement shall be construed to relieve the Trustee or the Certificate Administrator from liability for its own
negligent action, its own negligent failure to act or its own willful misconduct or bad faith; provided, however,
that:


 


(i)            Prior
to the occurrence of a Servicer Termination Event, and after the curing of all such Servicer Termination Events which may have

the Trustee nor the Certificate Administrator, as applicable, shall be liable for an error of judgment made in good faith by a

that the Trustee or the Certificate Administrator, as applicable, was negligent in ascertaining the pertinent facts; and

otherwise provided in Section 8.01:


 


(i)           The
Trustee and the Certificate Administrator may rely upon and shall be protected in acting or refraining from acting upon any resolution,
direction of the Depositor, Officer’s Certificate, certificate of auditors or any other certificate, statement, instrument,
opinion, report, notice, request, consent, order, Appraisal, bond or other paper or document reasonably believed by it to be genuine
and to have been signed or presented by the proper party or parties;

be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good
faith and in accordance therewith;


 


(iii)         Neither
the Trustee nor the Certificate Administrator shall be under any obligation to exercise any of the trusts or powers vested in it
by this Agreement or the Certificates or to make any investigation of matters arising hereunder or to institute, conduct or defend
any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders, pursuant to
the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee or the Certificate Administrator,
as applicable, reasonable security or indemnity satisfactory to it, against the costs, expenses and liabilities which may be incurred
therein or thereby; neither the Trustee nor the Certificate Administrator shall be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights
or powers, if it shall have reasonable grounds for believing that repayment of such funds or reasonable indemnity satisfactory
to it against such risk or liability is not reasonably assured to it; nothing contained herein shall, however, relieve the Trustee
of the obligation, upon the occurrence of a Servicer Termination Event which has not been cured, to exercise such of the rights
and powers vested in it by this Agreement, and to use the same degree of care and skill in their exercise as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs;


 


(iv)         Neither
the Trustee nor the Certificate Administrator shall be liable for any action reasonably taken, suffered or omitted by it in good
faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement;


 


(v)          Prior
to the occurrence of a Servicer Termination Event hereunder and after the curing of all Servicer Termination Events which may have
occurred, neither the Trustee nor the Certificate Administrator shall be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond
or other paper or document, unless requested in writing to do so by Holders of Certificates entitled to more than 50% of the Voting
Rights; provided, however, that if the payment within a reasonable time to the Trustee or the Certificate Administrator
of the costs, expenses or liabilities likely to be


 






     -480-


     


    

 


incurred by it in the making of such investigation is, in the opinion of the
Trustee or the Certificate Administrator, respectively, not reasonably assured to the Trustee or the Certificate Administrator
by the security afforded to it by the terms of this Agreement, the Trustee or the Certificate Administrator, respectively, may
require reasonable indemnity satisfactory to it from such requesting Holders against such expense or liability as a condition to
taking any such action. The reasonable expense of every such reasonable examination shall be paid by the requesting Holders;


 


(vi)         The
Trustee or the Certificate Administrator may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents or attorneys; provided, however, that the appointment of such agents or attorneys

that the Trustee or the Certificate Administrator, as the case may be, may not perform any duties hereunder through any Person
that is a Prohibited Party;


 


(vii)        For
all purposes under this Agreement, neither the Trustee nor the Certificate Administrator shall be deemed to have actual knowledge
or notice of any Servicer Termination Event or Asset Representations Reviewer Termination Event or any act, failure or breach of
any Person upon the occurrence of which the Trustee or the Certificate Administrator may be required to act unless a Responsible
Officer of the Trustee or the Certificate Administrator, as applicable, has actual knowledge thereof or unless written notice of

(viii)       Neither
the Trustee nor the Certificate Administrator shall be responsible for any act or omission of the Master Servicer or the Special
Servicer (unless the Trustee is acting as Master Servicer or the Special Servicer, as the case may be, in which case the Trustee
shall only be responsible for its own actions as Master Servicer or the Special Servicer) or of the Depositor, the Operating Advisor
or the Asset Representations Reviewer;


 


(ix)          Neither
the Trustee nor the Certificate Administrator shall in any way be liable by reason of any insufficiency in the Trust Fund unless
it is determined by a court of competent jurisdiction that the Trustee’s or Certificate Administrator’s, as applicable,
negligence or willful misconduct was the primary cause of such insufficiency;


 


(x)           In
no event shall the Trustee or the Certificate Administrator be liable for any failure or delay in the performance of its obligations
hereunder due to force majeure or acts of God; provided that such failure or delay is not also a result of its own negligence,
bad faith or willful misconduct;


 


(xi)          Except
as otherwise expressly set forth in this Agreement, Wells Fargo Bank, National Association, acting in any particular capacity hereunder
shall not be deemed to be imputed with knowledge of (a) Wells Fargo Bank, National Association, acting in a capacity that is unrelated

or (b) Wells Fargo Bank, National Association, acting in any other capacity
hereunder, except, in the case of either clause (a) or clause (b), where some or all of the obligations performed
in such capacities are performed by one or more employees within the same group or division of Wells Fargo Bank, National Association,
or where the groups or divisions responsible for performing the obligations in such capacities have one or more of the same Responsible
Officers;


 


(xii)         Nothing
herein shall require the Trustee or the Certificate Administrator to act in any manner that is contrary to applicable law; and

and protections relative to the Trust.


 


Each of the Certificate
Administrator, Custodian, Certificate Registrar, 17g-5 Information Provider and Authenticating Agent shall be entitled to the same
rights, indemnities, immunities, privileges and protections afforded to the Trustee hereunder in the same manner as if such party
were the named Trustee herein.

of the Trustee or the Certificate Administrator in Sections 2.02 and 2.04 and the signature, if any, of the
Certificate Registrar and Authenticating Agent set forth on any outstanding Certificate, shall be taken as the statements of
the Depositor, the Master Servicer or the Special Servicer, as the case may be, and the Trustee or the Certificate
Administrator assume no responsibility for their correctness. Neither the Trustee nor the Certificate Administrator makes any
representations as to the validity or sufficiency of this Agreement (other than as to this Agreement being a valid obligation
of the Trustee and the Certificate Administrator) or of any Certificate (other than as to the signature, if any, of the
Trustee or the Certificate Administrator set forth thereon) or of any Mortgage Loan or of any Trust Subordinate Companion

application by the Depositor of any of the Certificates issued to it or of the proceeds of such Certificates, or for the use
or application of any funds paid to the Depositor in respect of the assignment of the Mortgage Loans and the Trust
Subordinate Companion Loans to the Trust, or any funds deposited in or withdrawn from the Collection Account or any other
account by or on behalf of the Depositor, the Master Servicer, the Special Servicer or in the case of the Trustee,
the Certificate Administrator. The Trustee and the Certificate Administrator shall not be responsible for and may rely upon
the accuracy or content of any resolution, certificate, statement, opinion, report, document, order or other instrument
furnished by the Depositor, the Master Servicer or the Special Servicer and accepted by the Trustee or the Certificate
Administrator, in good faith, pursuant to this Agreement.


 


Section

may deal with the Depositor, the Master Servicer, the Special Servicer or the Underwriters in banking


 






     -482-


     


    

 


transactions,
with the same rights it would have if it were not Trustee or the Certificate Administrator.


 


Section
8.05     Fees and Expenses of Trustee and Certificate Administrator; Indemnification of Trustee and Certificate
Administrator. (a) As compensation for the performance of its duties hereunder, the Trustee shall be paid its portion of
the Certificate Administrator/Trustee Fee, which shall cover recurring and otherwise reasonably anticipated expenses of the
Trustee. As compensation for the performance of its duties hereunder, the Certificate Administrator shall be paid its portion
of the Certificate Administrator/Trustee Fee, which shall cover recurring and otherwise reasonably anticipated expenses of
the Certificate Administrator. The Certificate Administrator shall pay the Trustee the Trustee’s portion of the
Certificate Administrator/Trustee Fee. The Certificate Administrator/Trustee Fee shall be paid monthly on a Mortgage
Loan-by-Mortgage Loan (including the Trust Subordinate Companion Loans) basis. As to each Mortgage Loan, Trust Subordinate
Companion Loan and REO Loan (other than the portion of an REO Loan related to any Companion Loan (other than any Trust

the Stated Principal Balance of such Mortgage Loan or the Trust Subordinate Companion Loans, as applicable, and a 360-day
year consisting of twelve 30-day months. The Certificate Administrator/Trustee Fee (which shall not be limited to any
provision of law in regard to the compensation of a trustee of an express trust) shall constitute the Trustee’s and the
Certificate Administrator’s sole form of compensation for all services rendered by them in the execution of the trusts
hereby created and in the exercise and performance of any of the powers and duties of the Trustee and Certificate
Administrator hereunder, except for the reimbursement of expenses specifically provided for herein. The Certificate
Administrator/Trustee Fee shall not be payable with respect to any Companion Loan (other than the Trust Subordinate Companion
Loans).


 


(b)            The
Trustee, the Certificate Administrator (in each case, including in its capacity as Custodian and in its individual capacity) and
any director, officer, employee, representative or agent of the Trustee and the Certificate Administrator, respectively, shall
be indemnified and held harmless by the Trust (to the extent of amounts on deposit in the Collection Account, the Lower-Tier REMIC
Distribution Account or the Trust Subordinate Companion Loan REMIC Distribution Accounts, as applicable, from time to time) against
any loss, liability or expense (including, without limitation, costs and expenses of litigation, and of enforcement of this indemnity,
and of investigation, counsel fees, damages, judgments and amounts paid in settlement, and expenses incurred in becoming the successor
to the Master Servicer or the Special Servicer, to the extent not otherwise paid hereunder) arising out of, or incurred in connection
with, any act or omission of the Trustee or the Certificate Administrator, respectively, relating to the exercise and performance
of any of the powers, rights and duties of the Trustee or the Certificate Administrator, respectively (including in any capacities
in which they serve, such as paying agent, REMIC Administrator, Authenticating Agent, Custodian, Certificate Registrar and 17g-5

any of the other above specified Persons shall be entitled to indemnification pursuant to this Section 8.05(b) for (i) allocable
overhead, (ii) expenses or disbursements incurred or made by or on behalf of the Trustee or the Certificate Administrator,


 






     -483-


     


    

 


respectively,
in the normal course of the Trustee or the Certificate Administrator, respectively, performing its duties in accordance with any
of the provisions hereof, which are not “unanticipated expenses of the REMIC” within the meaning of Treasury Regulations
Section 1.860G-1(b)(3)(ii), (iii) any expense or liability specifically required to be borne thereby pursuant to the terms hereof
or (iv) any loss, liability or expense incurred by reason of willful misconduct, bad faith or negligence in the performance of
the Trustee’s or the Certificate Administrator’s, respectively, obligations and duties hereunder, or by reason of negligent
disregard of such obligations or duties, or as may arise from a breach of any representation or warranty of the Trustee specified
in Section 8.12 or the Certificate Administrator specified in Section 8.14, respectively, made herein. The provisions
of this Section 8.05(b) shall survive the termination of this Agreement and any resignation or removal of the Trustee or
the Certificate Administrator, respectively, and appointment of a successor thereto. The foregoing indemnity shall also apply to
the Certificate Administrator in all of its capacities hereunder, including Custodian, Certificate Registrar and Authenticating
Agent.


 


(c)            The
Certificate Administrator shall indemnify and hold harmless the Depositor and Mortgage Loan Sellers from and against any claims,
losses, damages, penalties, fines, forfeitures, legal fees and expenses and related costs, judgments and other costs and expenses
incurred by the Depositor, any Mortgage Loan Seller or its Affiliates that arise out of or are based upon (i) a breach by the Certificate
Administrator, in its capacity as 17g-5 Information Provider or in any other capacity in which the Certificate Administrator is
required to make available information to a Privileged Person that is an NRSRO, of its obligations under this Agreement or (ii)
negligence, bad faith or willful misconduct on the part of the Certificate Administrator, in its capacity as 17g-5 Information
Provider or in any other capacity in which the Certificate Administrator is required to make available information to a Privileged
Person that is an NRSRO, in the performance of such obligations or its negligent disregard of its obligations and duties under
this Agreement.


 


Section
8.06     Eligibility Requirements for Trustee and Certificate Administrator. Each of the Trustee and the Certificate
Administrator hereunder shall at all times be, and will be required to resign if it fails to be, (i) a corporation, national
bank, national banking association or a trust company, organized and doing business under the laws of any state or the United
States of America, authorized under such laws to exercise corporate trust powers and to accept the trust conferred under this
Agreement, having a combined capital and surplus of at least $100,000,000 and subject to supervision or examination by
federal or state authority and in the case of the Trustee, shall not be an Affiliate of the Master Servicer or the Special
Servicer (except during any period when the Trustee is acting as, or has become successor to, the Master Servicer or the
Special Servicer, as the case may be, pursuant to Section 7.02), (ii) an institution insured by the Federal Deposit
Insurance Corporation, (iii) an institution whose long-term senior unsecured debt is rated at least “BBB+” by
S&P, “A-” by Fitch and, if rated by KBRA, “A” by KBRA; provided
that the Trustee shall not become ineligible to serve based on a failure to satisfy such rating requirements as long as (a)
it maintains a long-term unsecured debt rating of no less than “BBB” by S&P and “A-” by Fitch,
(b) its short term debt obligations have a short term rating of not less than “A-1” from S&P and
“F1” by Fitch and (c) the Master Servicer maintains a long term unsecured rating of at least “A” by
S&P and “A+” by Fitch; provided that nothing in this proviso shall impose on the Master Servicer
any obligation to maintain such rating; provided, further, that if any such institution is not rated by DBRS or

     -484-


     


    

 


higher) rating by any two other NRSROs (which may include any of the Rating Agencies) or

surplus of such corporation, national bank or national banking association shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. In the event the place of business from which the Certificate
Administrator administers the Trust REMICs or the Grantor Trust or in which the Trustee’s office is located is in a state
or local jurisdiction that imposes a tax on the Trust on the net income of a REMIC (other than a tax corresponding to a tax imposed
under the REMIC Provisions) or a grantor trust, the Certificate Administrator or the Trustee, as applicable, shall elect either
to (i) resign immediately in the manner and with the effect specified in Section 8.07, (ii) pay such tax at no expense to
the Trust or (iii) administer the Trust REMICs and/or the Grantor Trust, as applicable, from a state and local jurisdiction that
does not impose such a tax.


 


Section
8.07     Resignation and Removal of the Trustee and Certificate Administrator. (a) The Trustee and the Certificate
Administrator may at any time resign and be discharged from the trusts hereby created by giving written notice thereof to the
Depositor, the Master Servicer, the Special Servicer and the Trustee or the Certificate Administrator, as applicable, the

Certificate Administrator shall post such notice to the Certificate Administrator’s Website in accordance with Section
3.13(b) and provide notice of such event to the Master Servicer, the Special Servicer, the Depositor and the 17g-5
Information Provider, which shall promptly post such notice to the 17g-5 Information Provider’s Website in accordance
with Section 3.13(c). Upon receiving such notice of resignation, the Depositor shall use its reasonable best efforts
to promptly appoint a successor trustee or successor certificate administrator acceptable to the Master Servicer and, prior
to the occurrence and continuance of a Control Termination Event, the Directing Holder by written instrument, in duplicate,
which instrument shall be delivered to the resigning Trustee or Certificate Administrator and to the successor trustee or
certificate administrator. A copy of such instrument shall be delivered to the Master Servicer, the Special Servicer, the
Certificateholders and the Trustee or Certificate Administrator, as applicable, by the Depositor. The resigning Trustee or
Certificate Administrator, as the case may be, shall pay all costs and expenses associated with the transfer of its duties.
If no successor trustee or certificate administrator shall have been so appointed and have accepted appointment within thirty
(30) days after the giving of such notice of resignation, the resigning Trustee or Certificate Administrator may petition any
court of competent jurisdiction for the appointment of a successor trustee or certificate administrator, as applicable. The
Trust shall pay all costs and expenses associated with such petition.


 


(b)            If
at any time the Trustee or Certificate Administrator shall cease to be eligible in accordance with the provisions of Section
8.06 (and in the case of the Certificate Administrator, Section 5.08) and shall fail to resign after written request
therefor by the Depositor or the Master Servicer, or if at any time the Trustee or Certificate Administrator shall become incapable
of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the


 






     -485-


     


    

 


Trustee or the Certificate Administrator or of its
property shall be appointed, or any public officer shall take charge or control of the Trustee or Certificate Administrator or
of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or if the Trustee or Certificate Administrator
(if different than the Trustee) shall fail (other than by reason of the failure of either the Master Servicer or the Special Servicer
to timely perform its obligations hereunder or as a result of other circumstances beyond the Trustee’s or Certificate Administrator’s,
as applicable, reasonable control) to timely publish any report to be delivered, published or otherwise made available by the Certificate
Administrator pursuant to Section 4.02 and such failure shall continue unremedied for a period of five (5) days, or if the
Certificate Administrator fails to make distributions required pursuant to Section 4.01 or Section 9.01, then the
Depositor may remove the Trustee or Certificate Administrator, as applicable, and appoint a successor trustee or certificate administrator
acceptable to the Master Servicer, by written instrument, in duplicate, which instrument shall be delivered to the Trustee or Certificate
Administrator so removed and to the successor trustee or certificate administrator in the case of the removal of the Trustee or
Certificate Administrator. A copy of such instrument shall be delivered to the Master Servicer, the Special Servicer and the Certificateholders
by the Depositor. Except as described in the following sentence, the terminated or removed Trustee or Certificate Administrator,
as applicable, shall bear all reasonable costs and expenses in connection with its termination or removal. If no successor trustee
or certificate administrator shall have been so appointed and have accepted appointment within ninety (90) days after the giving
of such notice of removal, the removed Trustee or Certificate Administrator may petition any court of competent jurisdiction for
the appointment of a successor trustee or certificate administrator, as applicable, at the expense of the Trust.


 


(c)            The
Holders of Certificates entitled to at least 50% of the Voting Rights may upon thirty (30) days’ prior written notice, with
or without cause, remove the Trustee or Certificate Administrator and appoint a successor trustee or certificate administrator
by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete
set of which instruments shall be delivered to the Master Servicer, one complete set to the Trustee or Certificate Administrator
so removed and one complete set to the successor so appointed. A copy of such instrument shall be delivered to the Depositor, the
Special Servicer and the remaining Certificateholders by the Master Servicer. In the event of any such termination without cause
pursuant to this Section 8.07(c), the successor trustee or certificate administrator, as applicable, shall be responsible
for all costs and expenses necessary to effect the transfer of responsibilities from its predecessor.


 


(d)            Any
resignation or removal of the Trustee or Certificate Administrator and appointment of a successor trustee or certificate administrator
pursuant to any of the provisions of this Section 8.07 shall not become effective until (i) acceptance of appointment by
the successor trustee or certificate administrator as provided in Section 8.08 and (ii) the Certificate Administrator shall
have filed any required Form 8-K pursuant to Section 11.07 hereof and any other Form 8-K filings have been completed with
respect to any related Companion Loan. Further, the resigning Trustee or Certificate Administrator, as the case may be, shall pay
all costs and expenses associated with the transfer of its duties.


 


If the same party is
acting as Trustee and Certificate Administrator pursuant to this Agreement, any removal of either such party in its capacity as
Trustee or Certificate


 






     -486-


     


    

  


Administrator, as applicable, shall also result in such party’s removal in its capacity as Trustee
or Certificate Administrator, as applicable, and the Depositor shall appoint a successor certificate administrator and a successor

the resignation, assignment, merger, consolidation, or transfer of the Trustee or its business to a successor, or upon the termination

the case of the Yorkshire & Lexington Towers Mortgage Loan, the Y&L Towers Trust Subordinate Companion Loan and in the
case of The Standard Highline NYC Mortgage Loan, the Standard Highline Trust Subordinate Companion Loan) (to the extent that the
original executed Mortgage Note for each Mortgage Loan (and the related Trust Subordinate Companion Loan, if applicable) was endorsed

for the registered Holders of CSAIL 2017-CX10 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series
2017-CX10 or in blank, and (ii) in the case of the other assignable Mortgage Loan documents (to the extent such other Mortgage
Loan documents were assigned to the outgoing trustee), assign such Mortgage Loan documents to such successor, and such successor
shall review the documents delivered to it or to the Custodian with respect to each Mortgage Loan (and the related Trust Subordinate
Companion Loan, if applicable), and certify in writing that, as to each Mortgage Loan (and the related Trust Subordinate Companion
Loan, if applicable) then subject to this Agreement, such endorsement and assignment has been made; (b) if any original executed
Mortgage Note for a Mortgage Loan (or Trust Subordinate Companion Loan) was not endorsed to the outgoing trustee, the Custodian

Holders of CSAIL 2017-CX10 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2017-CX10 or in blank;
provided, however, that, notwithstanding anything to the contrary herein, to the extent any such endorsement of such
Mortgage Note requires the signature of the related Mortgage Loan Seller in order to comply with the foregoing, then the Master
Servicer shall use reasonable efforts to cause the related Mortgage Loan Seller to execute such endorsement; (c) if any other assignable
Mortgage Loan or Trust Subordinate Companion Loan document was not assigned to the outgoing trustee, the Custodian shall, upon
its receipt of a Request for Release, deliver such Mortgage Loan or Trust Subordinate Companion Loan document to the Depositor
or the successor trustee, as requested, and the Master Servicer and the Depositor shall cooperate with any successor trustee to
ensure that such Mortgage Loan or Trust Subordinate Companion Loan document is assigned to such successor trustee; and (d) in any
case, such successor trustee shall review the documents delivered to it or to the Custodian with

respect to each Mortgage Loan
(and the related Trust Subordinate Companion Loan, if applicable) and certify in writing that, as to each Mortgage Loan (and the
related Trust Subordinate Companion Loan, if applicable) then subject to this Agreement, such endorsements and assignments have
been made or, in the event such endorsement or assignment cannot be made for any reason, to note the same in such certification.

certificate administrator appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the
Depositor, the Master Servicer, the Special Servicer and to its predecessor Trustee or Certificate Administrator an
instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee or
Certificate Administrator shall become effective and such successor trustee or certificate administrator without any further
act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with the like effect as if originally named as Trustee or Certificate Administrator herein. The
predecessor Trustee shall deliver to the successor trustee all Mortgage Files and related documents and statements held by it
hereunder (other than any Mortgage Files at the time held on its behalf by a Custodian, which Custodian, at Custodian’s
option shall become the agent of the successor trustee), and the Depositor, the Master Servicer, the Special Servicer and the
predecessor Trustee shall execute and deliver such instruments and do such other things as may reasonably be required to more
fully and certainly vest and confirm in the successor trustee all such rights, powers, duties and obligations, and to enable
the successor trustee to perform its obligations hereunder.


 


(b)            No
successor trustee or successor certificate administrator shall, as applicable, accept appointment as provided in this Section
8.08 unless at the time of such acceptance such successor trustee or successor certificate administrator, as applicable, shall

certificate administrator shall cause such notice to be delivered at the expense of the Master Servicer.


 


Section

be the successor of the Trustee or the Certificate Administrator, as applicable, hereunder; provided that, in the case
of the Trustee, such successor person shall be eligible under the provisions of Section 8.06, without the execution or
filing of any paper or any


 






     -488-


     


    

 


further act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding. The Certificate Administrator shall post such notice to the Certificate Administrator’s Website in
accordance with Section 3.13(b) and shall provide notice of such event to the Master Servicer, the Special Servicer,
the Depositor and the 17g-5 Information Provider, which shall post such notice to the 17g-5 Information Provider’s

Section 8.10     Appointment
of Co-Trustee or Separate Trustee. (a) Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction
in which any part of the Trust Fund or property securing the same may at the time be located, the Master Servicer and the Trustee
acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the
Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any

and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Master
Servicer and the Trustee may consider necessary or desirable. If the Master Servicer shall not have joined in such appointment
within fifteen (15) days after the receipt by it of a request to do so, or in case a Servicer Termination Event shall have occurred
and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder
shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 hereunder and no notice to
Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08.
All co-trustee fees shall be payable out of the Trust Fund.


 


(b)            In
the case of any appointment of a co-trustee or separate trustee pursuant to this Section 8.10, all rights, powers, duties
and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee
and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in which any particular
act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer or the Special Servicer hereunder),
the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to the Trust or any portion thereof in any such jurisdiction) shall be exercised and performed
by such separate trustee or co-trustee at the direction of the Trustee.


 


(c)            Any
notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then-separate trustees
and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall
refer to this Agreement and the conditions of this Article VIII. Each separate trustee and co-trustee, upon its acceptance of the
trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with
the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including
every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee.
Every such instrument shall be filed with the Trustee.


 


(d)            Any
separate trustee or co-trustee may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full power and authority,
to the extent not prohibited by law, to


 






     -489-


     


    

  


do any lawful act under or in respect of this Agreement on its behalf and in its name.
If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties,
rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment
of a new or successor trustee.


 


(e)            The
appointment of a co-trustee or separate trustee under this Section 8.10 shall not relieve the Trustee of its duties and
responsibilities hereunder.


 


Section
8.11     Appointment of Custodians. The Certificate Administrator is hereby appointed as the
Custodian to hold all or a portion of the Mortgage Files. The Custodian shall be a depository institution subject to
supervision by federal or state authority, shall have combined capital and surplus of at least $15,000,000 and shall be
qualified to do business in the jurisdiction in which it holds any Mortgage File. The Custodian shall be subject to the same
obligations and standard of care as would be imposed on the Certificate Administrator hereunder in connection with the
retention of Mortgage Files directly by the Certificate Administrator. Upon termination or resignation of the Custodian, the
Certificate Administrator may appoint another Custodian meeting the foregoing requirements. The appointment of one or more
Custodians by the Certificate Administrator shall not relieve the Certificate Administrator from any of its
obligations hereunder, and the Certificate Administrator shall remain responsible for all acts and omissions of any
Custodian. Any Custodian appointed hereunder must maintain a fidelity bond and errors and omissions policy in an amount
customary for Custodians which serve in such capacity in commercial mortgage loan securitization transactions, or may
self-insure.

     -494-


     


    

 


that in no
event shall the trust created hereby continue beyond the expiration of twenty-one (21) years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United States to the Court of St. James’s,
living on the date hereof.


 


Following the date on
which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5,
Class A-SB, Class X-A, Class X-B, Class A-S, Class B and Class C Regular Interests have been reduced to zero (and provided

Companion Loans and the Trust’s portion of each REO Property remaining in the Trust in accordance with the preceding sentence,
such Sole Certificateholder, not later than the Distribution Date on which the final distribution on the Certificates is to occur,

Servicer, the Special Servicer, the Trustee and the Certificate Administrator hereunder through the date of the liquidation of
the Trust that may be withdrawn from the Collection Account, or an escrow account acceptable to the respective parties hereto,
pursuant to Section 3.05(a) or that may be withdrawn from the Distribution Account pursuant to Section 3.05(a), but
only to the extent that such amounts are not already on deposit in the Collection Account, and (ii) be deemed to pay to the Trust
(which amount shall be further deemed distributed to the Holders of all outstanding Certificates) an amount equal to the Termination
Purchase Amount. In addition, the Master Servicer shall transfer all amounts required to be transferred to the Lower-Tier REMIC
Distribution Account and Excess Interest Distribution Account on the P&I Advance Date related to such Distribution Date in
which the final distribution on the Certificates is to occur from the Collection Account pursuant to the first paragraph of Section

Z Certificates and Class R Certificates) on the applicable Distribution Date, the Custodian shall, upon receipt of a Request for
Release from the Master Servicer, release or cause to be released to the Sole Certificateholder or any designee thereof, the Mortgage
Files for the remaining Mortgage Loans and the Trust Subordinate Companion Loans and shall execute all assignments, endorsements
and other instruments furnished to it by the Sole Certificateholder as shall be necessary to effectuate transfer of the Mortgage
Loans, the Trust


 






     -495-


     


    

 


Subordinate Companion Loans and REO Properties remaining in the Trust Fund, and the Trust shall be liquidated
in accordance with Section 9.02. Solely for federal income tax purposes, the Sole Certificateholder shall be deemed to have
purchased the assets of the Lower-Tier REMIC for an amount equal to the remaining Certificate Balance of the Principal Balance
Certificates, plus accrued, unpaid interest with respect thereto, and the Certificate Administrator shall credit such amounts against
amounts distributable in respect of such Certificates and Related Lower-Tier Regular Interests.


 


The obligations and responsibilities
under this Agreement of the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator and
the Companion Paying Agent shall terminate with respect to any Companion Loan to the extent (i) its related Serviced Mortgage Loan
has been paid in full or is no longer part of the Trust Fund and (ii) no amounts payable by the related Companion Holder to or
for the benefit of the Trust or any party hereto in accordance with the related Intercreditor Agreement remain due and owing.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates, in that order of
priority, may, at their option, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies
in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s portion of each REO Property
remaining in the Trust Fund as contemplated by clause (ii) of the first paragraph of this Section 9.01 by giving
written notice to the Trustee, the Certificate Administrator, and the other parties hereto no later than sixty (60) days prior
to the anticipated date of purchase; provided, however, that the Holders of the Controlling Class, the Special Servicer,
the Master Servicer, or the Holders of the Class R Certificates may so elect to purchase all of the Mortgage Loans, the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund only on or after the first Distribution
Date on which the aggregate Stated Principal Balance of the Mortgage Loans, the Trust Subordinate Companion Loans and any REO Mortgage
Loans held by the Trust is equal to or greater than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans and the Trust
Subordinate Companion Loans (solely for the purposes of this calculation, if such right is being exercised after December 2027
and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate
Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Preliminary
Statement.


 


In the event that the
Master Servicer or the Special Servicer purchases, or the Holders of the majority of the Controlling Class or the Holders of the
Class R Certificates purchase, all of the Mortgage Loans, the Trust Subordinate Companion Loans and the Trust’s portion of

Section
10.01  REMIC Administration. (a) The Certificate Administrator shall make elections or cause elections to be made to
treat each Trust REMIC as a REMIC under the Code and, if necessary, under Applicable State and Local Tax Law. Each such
election will be made on Form 1066 or other appropriate federal tax return for the taxable year ending on the last day of the
calendar year in which the Lower-Tier Regular Interests, the Trust Subordinate Companion Loan REMIC Regular Interests and the
Regular Interests are issued. For the purposes of the REMIC election in respect of the Upper-Tier REMIC, each Class of the
Regular Interests shall be designated as the “regular interests” and the Class UR Interest shall be designated as
the sole class of “residual interests” in the Upper-Tier REMIC. For purposes of the REMIC election in respect of
the Y&L Towers Trust Subordinate Companion Loan REMIC, the Y&L Towers Trust Subordinate Companion Loan REMIC Regular
Interests shall be designated as the “regular interests” and the Class UES-R Interest shall be designated as the
sole class of “residual interests” in the Y&L Towers Trust Subordinate Companion Loan REMIC. For purposes of
the REMIC election in respect of the Standard Highline Trust Subordinate Companion Loan REMIC, the Standard Highline Trust

Lower-Tier Regular Interests shall be designated as a class of “regular interests” and the Class LR Interest
shall be designated as the sole class of “residual interests” in the Lower-Tier REMIC. None of the
Special Servicer, the Master Servicer or the Trustee shall permit the creation of any “interests” (within the
meaning of Section 860G of the Code) in any Trust REMIC other than the foregoing interests.


 


(b)            The
Closing Date is hereby designated as the “startup day” (the “Startup Day”) of each Trust REMIC within the
meaning of Section 860G(a)(9) of the Code.


 


(c)            The
Certificate Administrator shall act on behalf of each Trust REMIC in relation to any tax matter or controversy involving either
such REMIC and shall represent each such REMIC in any administrative or judicial proceeding relating to an examination or audit
by any governmental taxing authority with respect thereto. The legal expenses, including without limitation attorneys’ or
accountants’ fees, and costs of any such proceeding and any liability resulting therefrom shall be expenses of the Trust
and the Certificate Administrator shall be entitled to reimbursement therefor out of amounts attributable to the Mortgage Loans,
the Trust Subordinate Companion Loans and any REO Properties on deposit in the Collection Account as provided by Section 3.05(a)
unless such legal expenses and costs are incurred by reason of the Certificate Administrator’s willful misconduct, bad faith
or negligence. By their acceptance thereof, the Holders of the largest Percentage Interest of the Class R Certificates shall be
designated as the “tax matters person”, in the manner provided under Treasury Regulations Section 1.860F-4(d) and Treasury
Regulations Section 301.6231(a)(7)-1, and the “partnership representative”, within the meaning of Section 6223 of the
Code (to the extent such provision is


 






     -499-


     


    

 


applicable to the Trust REMICs) of each Trust REMIC. By their acceptance thereof, the Holders
of the largest Percentage Interest of the Class R Certificates hereby agree to irrevocably appoint the Certificate Administrator
as their agent to perform all of the duties of the “tax matters person” and “partnership representative”
for the Trust REMICs.


 


(d)            The
Certificate Administrator shall prepare or cause to be prepared and shall file, or cause to be filed, all of the Tax Returns that
it determines are required with respect to each Trust REMIC created hereunder, and shall cause the Trustee to sign (and the Trustee
shall timely sign) such Tax Returns in a timely manner. The ordinary expenses of preparing such returns shall be borne by the Certificate
Administrator without any right of reimbursement therefor.


 


(e)            The
Certificate Administrator shall provide or cause to be provided (i) to any Transferor of a Class R Certificate such information
as is necessary for the application of any tax relating to the transfer of such Class R Certificate to any Person who is a Disqualified
Organization, or in the case of a Transfer to an agent thereof, to such agent, (ii) to the Certificateholders such information
or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original issue discount
and market discount or premium (using the Prepayment Assumption) and (iii) to the Internal Revenue Service, in respect of each
Trust REMIC, Form 8811, within thirty (30) days after the Closing Date.


 


(f)             The
Certificate Administrator shall take such actions and shall cause the Trust to take such actions as are reasonably within the Certificate
Administrator’s control and the scope of its duties more specifically set forth herein as shall be necessary to maintain
the status of each Trust REMIC as a REMIC under the REMIC Provisions and the Trustee shall assist the Certificate Administrator
to the extent reasonably requested by the Certificate Administrator to do so. Neither the Master Servicer nor the Special Servicer
shall knowingly or intentionally take any action, cause the Trust to take any action or fail to take (or fail to cause to be taken)
any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions,
if taken or not taken, as the case may be, could (i) cause any Trust REMIC to fail to qualify as a REMIC or (ii) result in the
imposition of a tax upon any Trust REMIC or the Trust (including but not limited to the tax on “prohibited transactions”
as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code,
but not including the tax on “net income from foreclosure property”) (either such event, an “Adverse REMIC
Event”) unless the Certificate Administrator receives an Opinion of Counsel (at the expense of the party seeking to take
such action or, if such party fails to pay such expense, and the Certificate Administrator determines that taking such action is
in the best interest of the Trust and the Certificateholders, at the expense of the Trust, but in no event at the expense of the
Certificate Administrator or the Trustee) to the effect that the contemplated action will not, with respect to the Trust, any Trust
REMIC created hereunder, endanger such status or, unless the Certificate Administrator determines in its sole discretion to indemnify
the Trust against such tax, result in the imposition of such a tax (not including a tax on “net income from foreclosure property”).
The Trustee shall not take or fail to take any action (whether or not authorized hereunder) as to which the Certificate Administrator
has advised it in writing that it has received an Opinion of Counsel to the effect that an Adverse REMIC Event could occur with
respect to such action. The Certificate Administrator may consult with counsel to make such written advice, and the cost of same
shall be borne by the


 






     -500-


     


    

 


party seeking to take the action not expressly permitted by this Agreement, but in no event at the expense
of the Certificate Administrator or the Trustee. At all times as may be required by the Code, the Certificate Administrator will
to the extent within its control and the scope of its duties more specifically set forth herein, maintain substantially all of
the assets of each Trust REMIC as “qualified mortgages” as defined in Section 860G(a)(3) of the Code and “permitted
investments” as defined in Section 860G(a)(5) of the Code.


 


(g)            In
the event that any applicable federal, state or local tax, including interest, penalties or assessments, additional amounts or
additions to tax, is imposed on any Trust REMIC, such tax shall be charged against amounts otherwise distributable to the Holders
of the Certificates, except as provided in the last sentence of this Section 10.01(g); provided that with respect
to the estimated amount of tax imposed on any “net income from foreclosure property” pursuant to Section 860G(c) of
the Code or any similar tax imposed by a state or local tax authority, the Special Servicer shall retain in the related REO Account
a reserve for the payment of such taxes in such amounts and at such times as it shall deem appropriate (or as advised by the Certificate
Administrator in writing), and shall remit to the Master Servicer such reserved amounts as the Master Servicer shall request in
order to pay such taxes. Except as provided in the preceding sentence, the Master Servicer shall withdraw from the Collection Account
sufficient funds to pay or provide for the payment of, and to actually pay, such tax as is estimated to be legally owed by any
Trust REMIC (but such authorization shall not prevent the Certificate Administrator from contesting, at the expense of the Trust
(other than as a consequence of a breach of its obligations under this Agreement), any such tax in appropriate proceedings, and
withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The Certificate Administrator is
hereby authorized to and shall segregate, into a separate non-interest bearing account, the net income from any “prohibited
transaction” under Section 860F(a) of the Code or the amount of any taxable contribution to any Trust REMIC after the Startup
Day that is subject to tax under Section 860G(d) of the Code and use such income or amount, to the extent necessary, to pay such
prohibited transactions tax. To the extent that any such tax (other than any such tax paid in respect of “net income from
foreclosure property”) is paid to the Internal Revenue Service or applicable state or local tax authorities, the Certificate
Administrator shall retain an equal amount from future amounts otherwise distributable to the Holders of Class R Certificates (as
applicable) and shall distribute such retained amounts, (w) in the case of the Y&L Towers Trust Subordinate Companion Loan
REMIC Regular Interests, to the Upper-Tier REMIC to the extent they are fully reimbursed for any Y&L Towers Realized Losses
arising therefrom and then to the Holders of the Class R Certificates in respect of the Class UES-R Interest respectively in the
manner specified in Section 4.01(c), (x) in the case of the Standard Highline Trust Subordinate Companion Loan REMIC Regular
Interests, to the Upper-Tier REMIC to the extent they are fully reimbursed for any Standard Highline Realized Losses arising therefrom
and then to the Holders of the Class R Certificates in respect of the Class STN-R Interest respectively in the manner specified
in Section 4.01(c), (y) in the case of the Lower-Tier Regular Interests, to the Upper Tier REMIC to the extent they are
fully reimbursed for any Realized Losses arising therefrom and then to the Holders of the Class R Certificates in respect of the
Class LR Interest in the manner specified in Section 4.01(c) and (z) in the case of the Upper-Tier REMIC, to the Holders
of the Principal Balance Certificates in the manner specified in Section 4.01(a) or Section 4.01(b), as applicable,
to the extent they are fully reimbursed for any Realized Losses arising therefrom and then to the Holders of the Class R Certificates
in respect of the Class UR Interest. None of the Trustee, the Certificate


 






     -501-


     


    

 


Administrator, the Master Servicer or the Special Servicer
shall be responsible for any taxes imposed on any Trust REMIC except to the extent such taxes arise as a consequence of a breach

party.


 


(h)            The
Certificate Administrator shall, for federal income tax purposes, maintain or cause to be maintained books and records with respect
to each Trust REMIC on a calendar year and on an accrual basis or as otherwise may be required by the REMIC Provisions.


 


(i)             Following
the Startup Day, neither the Certificate Administrator nor the Trustee shall accept any contributions of assets to any Trust REMIC
unless the Certificate Administrator and the Trustee shall have received an Opinion of Counsel (at the expense of the party seeking
to make such contribution) to the effect that the inclusion of such assets in such Trust REMIC will not cause an Adverse REMIC
Event to occur.


 


(j)             Neither
the Certificate Administrator nor the Trustee shall enter into any arrangement by which the Trust or any Trust REMIC will receive
a fee or other compensation for services nor permit the Trust or any Trust REMIC to receive any income from assets other than “qualified
mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined in Section 860G(a)(5)
of the Code.


 


(k)            Solely
for the purposes of Treasury Regulations Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” by which
(i) the Certificate Balance or Notional Amount of each Class of Regular Interests representing a “regular interest”
in the Upper-Tier REMIC would be reduced to zero and (ii) the Lower-Tier Principal Amount of each Class of Lower-Tier Regular Interests
representing a “regular interest” in the Lower-Tier REMIC and the Trust Subordinate Companion Loan REMIC Regular Interests
would be reduced to zero is the date that is the Rated Final Distribution Date.


 


(l)             None
of the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable, shall sell, dispose
of or substitute for any of the Mortgage Loans or Trust Subordinate Companion Loans (except in connection with (i) the default,
imminent default or foreclosure of a Mortgage Loan or Trust Subordinate Companion Loan, including but not limited to, the acquisition
or sale of a Mortgaged Property acquired by foreclosure or deed in lieu of foreclosure, (ii) the bankruptcy of the Trust, (iii)
the termination of the Trust pursuant to Article IX of this Agreement or (iv) a purchase of Mortgage Loans or Trust Subordinate
Companion Loans pursuant to Article II or Article III of this Agreement) or acquire any assets for the Trust or any Trust
REMIC or sell or dispose of any investments in the Collection Account or the REO Account for gain unless it has received an Opinion
of Counsel that such sale, disposition or substitution will not (a) affect adversely the status of any Trust REMIC as a REMIC or
(b) unless the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable, has determined
in its sole discretion to indemnify the Trust against such tax, cause the Trust or any Trust REMIC to be subject to a tax on “prohibited
transactions” pursuant to the REMIC Provisions.


 


(m)           The
Certificate Administrator’s authority under this Agreement includes the authority to make, and the Certificate Administrator
is hereby directed to make, any elections

11.01, but in any event, shall, upon reasonable advance written request, provide information in sufficient time to allow
the Depositor and each Other Depositor to satisfy any related filing requirements. For purposes of this Article XI, to

(b)            Each
of the Master Servicer, the Special Servicer, the Sub-Servicer, the Trustee, the Operating Advisor (subject to Section 3.26(p)),
the Asset Representations Reviewer and the Certificate Administrator (each of the Master Servicer, the Special Servicer, the Trustee,
the Operating Advisor, the Asset Representations Reviewer and the Certificate Administrator and each Sub-Servicer, for purposes
of this Section 11.02, a “Servicer”) is permitted to utilize one or more Subcontractors to perform certain
of its obligations hereunder. If such Subcontractor will be a Servicing Function Participant, such Servicer shall promptly upon
written request provide to the Depositor or any Mortgage Loan Seller (and any Other Trustee, Other Certificate Administrator and
Other Depositor related to any Other Securitization that includes a related Serviced Companion Loan) a written description (in
form and substance satisfactory to the Depositor, such Mortgage Loan Seller or such Other Trustee, Other Certificate Administrator
or Other Depositor, as applicable) of the role and function of each Subcontractor utilized by such Servicer, specifying (i) the
identity of such Subcontractor and (ii) the elements of the Servicing Criteria that will be addressed in assessments of compliance
provided by each such Subcontractor. As a condition to the utilization by such Servicer of any Subcontractor determined to be a
Servicing Function Participant, such Servicer shall (i) with respect to any such Subcontractor engaged by such Servicer that is
an Initial Sub-Servicer, use commercially reasonable efforts to cause, and (ii) with respect to any other subcontractor with which
it has entered into a servicing relationship, cause such Subcontractor used by such Servicer for the benefit of the Depositor and
the Trustee (and any Other Trustee, Other Certificate Administrator and Other Depositor related to any Other Securitization that
includes a related Serviced Companion Loan) to comply with the provisions of Section 11.10 and Section 11.11 of this
Agreement to the same extent as if such Subcontractor were such Servicer. With respect to any Servicing Function Participant engaged
by such Servicer that is an Initial Sub-Servicer, such Servicer shall be responsible for using commercially reasonable efforts
to obtain, and with respect to each other Servicing Function Participant engaged by such Servicer, such Servicer shall obtain from
each such Servicing Function Participant and deliver to the applicable Persons any assessment of compliance report and related
accountant’s attestation required to be delivered by such Subcontractor under Section 11.10 and Section 11.11,
in each case, as and when required to be delivered. For the avoidance of doubt, the Custodian shall not be permitted to utilize
any Subcontractor to perform any of its obligations hereunder.


 


(c)            Notwithstanding
the foregoing, if a Servicer engages a Subcontractor, other than an Initial Sub-Servicer in connection with the performance of
any of its duties under this Agreement, such Servicer shall be responsible for determining whether such Subcontractor is a “servicer”
within the meaning of Item 1101 of Regulation AB and whether any such Subcontractor meets the criteria in Item 1108(a)(2)(i), (ii)
or (iii) of Regulation AB. If a Servicer determines, pursuant to the preceding sentence, that such Subcontractor is a “servicer”
within the meaning of Item 1101 of Regulation AB and meets the criteria in Item 1108(a)(2)(i), (ii) or (iii) of Regulation AB,
then such Subcontractor shall be deemed to be a Sub-Servicer for purposes of this Agreement, the engagement of such Sub-Servicer
shall not be effective unless and until notice is given to the Depositor and the Certificate Administrator of any such Sub-Servicer
and Sub-Servicing Agreement. Other than with respect to the Initial Sub-Servicer, no Sub-Servicing Agreement shall be effective
until fifteen (15) days after such written notice is received by the Depositor and the Certificate Administrator (or such shorter
period as is agreed to by the Depositor). Such notice shall contain all information reasonably necessary to enable the Certificate
Administrator to accurately and timely report the event under Item 6.02 of Form 8-K

pursuant to the Exchange Act (if such reports
under the Exchange Act are required to be filed under the Exchange Act).


 


(d)            In
connection with the succession to the Trustee under this Agreement by any Person (i) into which the Trustee may be merged or consolidated,
or (ii) which may be appointed as a successor to the Trustee, the Trustee shall deliver written notice to the Depositor, the Certificate
Administrator and the 17g-5 Information Provider, which shall promptly post such notice to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c), in each case at least thirty (30) calendar days prior to the effective date of such
succession or appointment (or if such prior notice is violative of applicable law or any applicable confidentiality agreement,
no later than one (1) Business Day after such effective date of succession) and shall furnish to the Depositor and the Certificate
Administrator, in writing and in form and substance reasonably satisfactory to the Depositor and the Certificate Administrator,
all information reasonably necessary for the Certificate Administrator to accurately and timely report, pursuant to Section
11.07, the event under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports under the Exchange Act are required
to be filed under the Exchange Act).


 


(e)            Notwithstanding
anything to the contrary contained in this Article XI, in connection with any Sub-Servicer and/or any Mortgage Loan (and/or
any Trust Subordinate Companion Loan) that is the subject of an Initial Sub-Servicing Agreement, with respect to all matters related
to Regulation AB, the Master Servicer shall not have any obligation other than to use commercially reasonable efforts to cause
such Sub-Servicer to comply with its obligations under such Initial Sub-Servicing Agreement.


 


(f)             Any
information furnished pursuant to this Section 11.02 shall also be provided to each Other Depositor and each Other Certificate
Administrator (to the extent the information relates to a party that services, specially services or is trustee for a Serviced
Companion Loan) in the same time frame as set forth in this Section 11.02.

11.04, 11.05, 11.06 and 11.07 of this Agreement, the Certificate Administrator shall prepare for
execution by the Depositor any Forms 8-K, 10-D, ABS-EE and 10-K required by the Exchange Act, in order to permit the timely

Each party hereto shall
be entitled to rely on the information in the Prospectus or this Agreement with respect to the identity of any “sponsor”,
credit enhancer, derivative provider or “significant obligor” as of the Closing Date other than with respect to itself
or any information required to be provided by it or indemnified for by it pursuant to any separate agreement.


 


(b)       In
the event that the Certificate Administrator is unable to timely file with the Commission all or any required portion of any Form
8-K, 10-D, ABS-EE or 10-K required to be filed by this Agreement because required disclosure information was either not delivered
to it

or delivered to it after the delivery deadlines set forth in this Agreement, the Certificate Administrator will promptly
notify the Depositor. In the case of Forms 10-D, ABS-EE and 10-K, the Depositor, the Master Servicer, the Certificate Administrator,
the Operating Advisor and the Trustee will thereupon cooperate to prepare and file a Form 12b-25 and a Form 10-D/A, Form ABS-EE/A
or Form 10-K/A, as applicable, pursuant to Rule 12b-25 of the Exchange Act. In the case of Form 8-K, the Certificate Administrator
will, upon receipt of all required Form 8-K Disclosure Information and upon the approval and direction of the Depositor, include
such disclosure information on the next succeeding Form 10-D to be filed for the Trust. In the event that any previously filed
Form 8-K, Form 10-D, Form ABS-EE or Form 10-K needs to be amended, the Certificate Administrator will notify the Depositor, and
such other parties as needed and the parties hereto will cooperate with the Certificate Administrator to prepare any necessary
Form 8-K/A, Form 10-D/A, Form ABS-EE/A or Form 10-K/A. Any Form 15, Form 12b-25 or any amendment to Form 8-K, Form 10-D, Form ABS-EE
or Form 10-K shall be signed by an officer of the Depositor. The parties to this Agreement acknowledge that the performance by
the Certificate Administrator of its duties under this Section 11.03 related to the timely preparation and filing of Form
15, a Form 12b-25 or any amendment to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K is contingent upon the parties observing all
applicable deadlines in the performance of their duties under Sections 11.03, 11.04, 11.05, 11.06,
11.07, 11.08, 11.09, 11.10 and 11.11 of this Agreement. The Certificate Administrator shall
have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare, arrange
for execution and/or timely file any such Form 15, Form 12b-25 or any amendments to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K,
where such failure results from the Certificate Administrator’s inability or failure to receive, on a timely basis, any information
from any other party hereto needed to prepare, arrange for execution or file such Form 15, Form 12b-25 or any amendments to Form
8-K, Form 10-D, Form ABS-EE or Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

any costs, liabilities, fees and expenses incurred by the depositor or such underwriters as a result of any material misstatements
or omissions or alleged material misstatements or omissions in any such offering material to the extent that such material misstatement
or omission was made in reliance upon any such information provided by the Trustee (where such information pertains to the Trustee
individually and not to any specific


 



     -527-

Section 12.01     Asset
Review.


 


(a)          On
or prior to each Distribution Date, based on either the CREFC® Delinquent Mortgage Loan Status Report or the CREFC®
Loan Periodic Update File, the Certificate Administrator shall determine if an Asset Review Trigger has occurred. If an Asset Review
Trigger is determined to have occurred, the Certificate Administrator shall promptly provide written notice to the Asset Representations
Reviewer and to all Pooled Certificateholders and each other party to this Agreement. Any notice required to be delivered to the
Pooled Certificateholders pursuant to this Section 12.01 shall be delivered by the Certificate Administrator by posting
such notice on the Certificate Administrator’s Website, by mailing to their addresses appearing in the Certificate Register
and by delivering such notice via the Depository. The Certificate Administrator shall include in the Form 10-D relating to the


 



     -532-


     


    

 


distribution period in which the Asset Review Trigger occurred a description of the events that caused the Asset Review Trigger
to occur. On each Distribution Date after providing such notice to the Pooled Certificateholders, the Certificate Administrator,
based on information provided to it by the Master Servicer, shall determine whether (1) any additional Mortgage Loan has become
a Delinquent Loan, (2) any Mortgage Loan has ceased to be a Delinquent Loan and (3) an Asset Review Trigger has ceased to exist,
and, if there is an occurrence of any of the events or circumstances identified in clauses (1), (2) and/or (3),
deliver written notice of such information (which may be via email) in the form of Exhibit SS within two (2) Business Days
to the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer.


 


If the Pooled Certificateholders
evidencing not less than 5% of the Pooled Voting Rights of the Certificates deliver to the Certificate Administrator, within 90
days after the filing of the Form 10-D reporting the occurrence of an Asset Review Trigger, a written direction requesting a vote
to commence an Asset Review (such written direction, the “Asset Review Vote Election”), then the Certificate
Administrator shall promptly provide written notice thereof to the Asset Representations Reviewer and to all Pooled Certificateholders
and conduct a solicitation of votes to authorize an Asset Review. Upon the affirmative vote to authorize an Asset Review of Holders
of Certificates evidencing at least a majority of an Asset Review Quorum within 150 days of receipt of the Asset Review Vote Election
(an “Affirmative Asset Review Vote”), the Certificate Administrator shall promptly provide written notice thereof
to all parties to this Agreement, the Underwriters, the Mortgage Loan Sellers, the Directing Holder, the Risk Retention Consultation
Party and the other Pooled Certificateholders (the “Asset Review Notice”). Upon receipt of an Asset Review Notice,
the Asset Representations Reviewer shall request access to the Secure Data Room by providing to the Certificate Administrator a
certification in the form attached hereto as Exhibit RR. Upon receipt of such certification, the Certificate Administrator
shall promptly (and in any case within two (2) Business Days after such receipt) grant the Asset Representations Reviewer access
to the Secure Data Room. In the event an Affirmative Asset Review Vote has not occurred within such 150-day period following the
receipt of the Asset Review Vote Election, no Pooled Certificateholder may request a vote or cast a vote for an Asset Review and
the Asset Representations Reviewer shall not be required to review any Delinquent Loan unless and until (A) an additional Mortgage
Loan has become a Delinquent Loan after the expiration of such 150-day period, (B) an additional Asset Review Trigger has occurred
as a result or otherwise is in effect, (C) the Certificate Administrator has timely received an Asset Review Vote Election after
the occurrence of the events described in clauses (A) and (B) in this sentence and (D) an Affirmative Asset Review
Vote has occurred within 150 days after the Asset Review Vote Election described in clause (C) in this sentence. After the
occurrence of any Asset Review Vote Election or an Affirmative Asset Review Vote, no Pooled Certificateholder may make any additional
Asset Review Vote Election except as described in the immediately preceding sentence. Any reasonable out-of-pocket expenses incurred
by the Certificate Administrator in connection with administering such vote will be paid as an expense of the Trust from the Collection
Account. The Certificate Administrator shall be entitled to administer any vote in connection with the foregoing through an agent.


 


(b)          (i)
If an Affirmative Asset Review Vote has occurred, the Certificate Administrator shall promptly provide written notice thereof to
all parties to this Agreement, the Underwriters, Sponsors, the Directing Holder, the Risk Retention Consultation Party and all
other Pooled Certificateholders. Upon receipt of an Asset Review Notice, the Custodian (with

respect to clauses (1) through
(5) for non-Specially Serviced Loans), the Master Servicer (with respect to clauses (6) and (7) for non-Specially
Serviced Loans) and the Special Servicer (with respect to Specially Serviced Loans), in each case to the extent in such party’s
possession, shall promptly, but in no event later than ten (10) Business Days (except with respect to clause (7)) after
receipt of such notice from the Certificate Administrator, provide the following materials to the Asset Representations Reviewer
(collectively, with the Diligence Files, a copy of the Prospectus, a copy of each related Mortgage Loan Purchase Agreement and
a copy of this Agreement posted to the Secure Data Room by the Certificate Administrator pursuant to Section 4.08 or to
the Certificate Administrator’s Website pursuant to Section 3.13(b), as applicable, the “Review Materials”):


 


(1)          a
copy of an assignment of the Mortgage in favor of the Trustee, with evidence of recording thereon, for each Delinquent Loan that
is subject to an Asset Review;


 


(2)          a
copy of an assignment of any related assignment of leases (if such item is a document separate from the Mortgage) in favor of the
Trustee, with evidence of recording thereon, related to each Delinquent Loan that is subject to an Asset Review;


 


(3)          a
copy of the assignment of all unrecorded documents relating to each Delinquent Loan that is subject to an Asset Review, if not
already covered pursuant to items (1) or (2) above;


 


(4)          a
copy of all filed copies (bearing evidence of filing) or evidence of filing of any UCC Financing Statements related to each Delinquent
Loan that is subject to an Asset Review;


 


(5)          a
copy of an assignment in favor of the Trustee of any financing statement executed and filed in the relevant jurisdiction related
to each Delinquent Loan that is subject to an Asset Review;


 


(6)          a
copy of any notice previously delivered to the applicable mortgage loan seller by the master servicer or the special servicer,
as applicable, of any alleged defect or breach with respect to any Delinquent Loan; and


 


(7)          any
other related documents or agreements that are reasonably requested by the Asset Representations Reviewer to be delivered by the
Master Servicer or the Special Servicer, as applicable, in the time frames and as otherwise described below.


 


(ii)          In
the event that, as part of an Asset Review of any Mortgage Loan, the Asset Representations Reviewer determines that it is missing
any documents or agreements that are required to be a part of the Review Materials for such Mortgage Loan or that were entered
into or delivered in connection with the origination or a modification of such Mortgage Loan and, in each case that are necessary
in connection with its completion of any such Asset Review, the Asset Representations Reviewer shall promptly, but in no event
later than ten (10) Business Days after receipt of the Review Materials, notify the Master Servicer (with respect to non-Specially
Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans), as applicable, of such missing


 



     -534-


     


    

 


documents and
agreements, and request the Master Servicer or the Special Servicer, as applicable, promptly, but in no event later than ten (10)
Business Days after receipt of such notification from the Asset Representations Reviewer, to deliver to the Asset Representations
Reviewer such missing documents and agreements to the extent in its possession. In the event any missing documents or agreements
are not provided by the Master Servicer or the Special Servicer, as applicable, within such ten (10) Business Day period, the Asset
Representations Reviewer shall contact the related Mortgage Loan Seller to request such documents or agreements from the Mortgage
Loan Seller. The Mortgage Loan Seller will be required to deliver such additional documents and agreements only to the extent in
the possession of such Mortgage Loan Seller.


 


(iii)         The
Asset Representations Reviewer may, but is under no obligation to, consider and rely upon information furnished to it by a Person
that is not a party to this Agreement or the related Mortgage Loan Seller, and shall do so only if such information can be independently
verified (without unreasonable effort or expense to the Asset Representations Reviewer) and is determined by the Asset Representations
Reviewer in its good faith and sole discretion to be relevant to the Asset Review (any such information, “Unsolicited
Information”) conducted pursuant to this Section 12.01 hereof.


 


(iv)         Upon
receipt by the Asset Representations Reviewer of the Asset Review Notice and access to the Review Materials with respect to a Delinquent
Loan, the Asset Representations Reviewer, as an independent contractor, shall commence an Asset Review. The Asset Representations
Reviewer shall perform an Asset Review with respect to each representation and warranty made by the related Mortgage Loan Seller
with respect to such Delinquent Loan in accordance with the Asset Review Standard and the procedures set forth on Exhibit QQ
(each such procedure, a “Test”). Once an Asset Review of a Mortgage Loan is completed, no further Asset Review
shall be required in respect of, or performed on, such Mortgage Loan notwithstanding that such Mortgage Loan may continue to be
a Delinquent Loan or again become a Delinquent Loan at a time when a new Asset Review Trigger occurs and a new Affirmative Asset
Review Vote is obtained subsequent to the occurrence of such new Asset Review Trigger.


 


(v)          No
Certificateholder shall have the right to change the scope of the Asset Review, and the Asset Representations Reviewer shall not
be required to review any information other than (x) the Review Materials and (y) if applicable, Unsolicited Information.


 


(vi)         The
Asset Representations Reviewer may, absent manifest error and subject to the Asset Review Standard, (i) assume, without independent
investigation or verification, that the Review Materials are accurate and complete in all material respects and (ii) conclusively
rely on such Review Materials.


 


(vii)        In
the event that the Asset Representations Reviewer determines that the Review Materials are insufficient to complete a Test and
such missing information and documentation is not delivered to the Asset Representations Reviewer by the Master Servicer (with
respect to non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) to the extent in the
Master Servicer’s or the Special


 



     -535-


     


    

 


Servicer’s possession within 10 Business Days or by the related Mortgage Loan Seller
upon request by the Asset Representations Reviewer shall list such missing information and documents in a preliminary report setting
forth the preliminary results of the application of the Tests and the reasons why such missing information and documents are necessary
to complete a Test and (if the Asset Representations Reviewer has so concluded) that the absence of such information and documents
will be deemed to be a failure of such Test. The Asset Representations Reviewer shall provide such preliminary report to the Master
Servicer (with respect to non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) and
the related Mortgage Loan Seller. If the preliminary report indicates that any of the representations and warranties fails or is
deemed to fail any Test, the related Mortgage Loan Seller shall have ninety (90) days (the “Cure/Contest Period”)
to remedy or otherwise refute the failure. Any information and documents provided or explanations given to support the Mortgage
Loan Seller’s claim that the representation and warranty has not failed a Test or that any missing information or documents
in the Review Materials are not required to complete a Test shall be promptly delivered by the related Mortgage Loan Seller to
the Asset Representations Reviewer. For the avoidance of doubt, the Asset Representations Reviewer shall not be required to prepare
a preliminary report in the event the Asset Representations Reviewer determines that there is no Test failure with respect to the
related Mortgage Loan.


 


(viii)       The
Asset Representations Reviewer shall, within the later of (x) 60 days after the date on which access to the Diligence Files in
the Secure Data Room is made available to the Asset Representations Reviewer by the Certificate Administrator or (y) 10 days after
the expiration of the Cure/Contest Period, complete an Asset Review with respect to each Delinquent Loan and deliver (i) a report
setting forth the Asset Representations Reviewer’s findings and conclusions as to whether or not it has determined there
is any evidence of a failure of any Test based on the Asset Review and a statement that the Asset Representations Reviewer’s
findings and conclusions set forth in such report were not influenced by any third party (an “Asset Review Report”)
to each party to this Agreement and the related Mortgage Loan Seller for each Delinquent Loan, and (ii) a summary of the Asset
Representations Reviewer’s conclusions included in such Asset Review Report (an “Asset Review Report Summary”)
to the Trustee and Certificate Administrator. The period of time by which the Asset Review Report must be completed and delivered
may be extended by up to an additional thirty (30) days, upon written notice to the parties to this Agreement and the related Mortgage
Loan Seller, if the Asset Representations Reviewer determines pursuant to the Asset Review Standard that such additional time is
required due to the characteristics of the Mortgage Loans and/or the Mortgaged Property or Mortgaged Properties. In no event may
the Asset Representations Reviewer determine whether any Test failure constitutes a Material Defect, or whether the Trust should
enforce any rights it may have against the related Mortgage Loan Seller, which, in each such case, will be the responsibility of
the Enforcing Servicer.


 


(ix)          In
addition, in the event that the Asset Representations Reviewer does not receive any information or documentation that it requested
from the Master Servicer (with respect to non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced
Loans) or the related Mortgage Loan Seller in sufficient time to allow the Asset Representations Reviewer to complete its Asset
Review and deliver an Asset Review


 



     -536-


     


    

 


Report, the Asset Representations Reviewer shall prepare the Asset Review Report solely based
on the information received by the Asset Representations Reviewer with respect to the related Delinquent Loan, and the Asset Representations
Reviewer shall have no responsibility to independently obtain any such information from any party to this Agreement.


 


(x)          Within
forty-five (45) days after receipt of an Asset Review Report with respect to any Mortgage Loan, the Special Servicer shall determine
whether at that time, based on the Servicing Standard, there exists a Material Defect with respect to such Mortgage Loan. If the
Special Servicer determines that a Material Defect exists, the Special Servicer shall enforce the obligations of the related Mortgage
Loan Seller with respect to such Material Defect in accordance with Section 2.03(b).


 


(xi)          For
the avoidance of doubt, the Asset Representations Reviewer shall not perform an Asset Review with respect to any Trust Subordinate
Companion Loan at any time.


 


(c)          The
Asset Representations Reviewer and its Affiliates shall keep all information appropriately labeled as “Privileged Information”
confidential and shall not disclose such Privileged Information to any Person (including Certificateholders), other than (1) to
the extent expressly required by this Agreement in an Asset Review Report or otherwise, to the other parties to this Agreement
with a notice indicating that such information is Privileged Information or (2) pursuant to a Privileged Information Exception.
Each party to this Agreement that receives Privileged Information from the Asset Representations Reviewer with a notice stating
that such information is Privileged Information shall not disclose such Privileged Information to any Person without the prior
written consent of the Special Servicer other than pursuant to a Privileged Information Exception.


 


(d)          The
Asset Representations Reviewer may delegate its duties to agents or subcontractors so long as the related agreements or arrangements
with such agents or subcontractors are consistent with the provisions of this Section 12.01; provided that no agent
or subcontractor may (1) be affiliated with a Sponsor, Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator,
the Trustee, the Directing Certificateholder or any of their respective Affiliates or (ii) have been paid any fees, compensation
or other remuneration by an Underwriter, Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator, the
Trustee, the Directing Certificateholder or any of their respective Affiliates in connection with due diligence or other services
with respect to any Mortgage Loan prior to the Closing Date. Notwithstanding the foregoing sentence, the Asset Representations
Reviewer shall remain obligated and primarily liable for any Asset Review required hereunder in accordance with the provisions
of this Agreement without diminution of such obligation or liability or related obligation or liability by virtue of such delegation
or arrangements or by virtue of indemnification from any Person acting as its agents or subcontractor to the same extent and under
the same terms and conditions as if the Asset Representations Reviewer alone were performing its obligations under this Agreement.
The Asset Representations Reviewer shall be entitled to enter into an agreement with any agent or subcontractor providing for indemnification
of the Asset Representations Reviewer by such agent or subcontractor, and nothing contained in this Agreement shall be deemed to
limit or modify such indemnification.

(e)          The
Asset Representations Reviewer may assign its rights and obligations under this Agreement in connection with the sale or transfer
of all or substantially all of its Asset Representations Reviewer portfolio, provided that: (i) the purchaser or transferee
accepting such assignment and delegation (A) is an Eligible Asset Representations Reviewer, organized and doing business under
the laws of the United States of America, any state of the United States of America or the District of Columbia, authorized under
such laws to perform the duties of the asset representations reviewer resulting from a merger, consolidation or succession that
is permitted under this Agreement, (B) executes and delivers to the Trustee and the Certificate Administrator an agreement that
contains an assumption by such person of the due and punctual performance and observance of each covenant and condition to be performed
or observed by the asset representations reviewer under this Agreement from and after the date of such agreement and (C) is not
a Prohibited Party under this Agreement; (ii) the Asset Representations Reviewer shall not be released from its obligations under
this Agreement that arose prior to the effective date of such assignment and delegation; (iii) the rate at which the Asset Representations
Reviewer Asset Review Fee (or any component thereof) is calculated shall not exceed the rate then in effect and (iv) the resigning
Asset Representations Reviewer shall be responsible for the reasonable costs and expenses of each other party to this Agreement
and the Rating Agencies in connection with such transfer. Upon acceptance of such assignment and delegation, the purchaser or transferee
shall provide notice to each party to this Agreement and then will be the successor asset representations reviewer hereunder.


 


(f)           With
respect to any Delinquent Loan that is an Non-Serviced Mortgage Loan, to the extent any documents required by the Asset Representations
Reviewer to complete a Test are missing or have not been received from the related Mortgage Loan Seller, the Asset Representations
Reviewer shall request such document(s) from the related Non-Serviced Master Servicer (if such Non-Serviced Mortgage Loan is being
serviced by a Non-Serviced Master Servicer) or the related Non-Serviced Special Servicer (if such Non-Serviced Serviced Mortgage
Loan is being serviced by a Non-Serviced Special Servicer), the related Non-Serviced Trustee and the related Non-Serviced Certificate
Administrator (and, in each case, such other party as contemplated under the related Non-Serviced PSA or related Intercreditor
Agreement).


 


Section 12.02      Payment
of Asset Representations Reviewer Fees and Expenses; Limitation of Liability. 


 


(a)          The
Asset Representations Reviewer shall be paid a fee of $5,000 (the “Asset Representations Reviewer Upfront Fee”)
on the Closing Date. As compensation for the performance of its routine duties, the Asset Representations Reviewer shall be paid
a fee (the “Asset Representations Reviewer Fee”), payable monthly from amounts received in respect of each Mortgage
Loan (including any Non-Serviced Mortgage Loan but excluding any Companion Loan) and REO Mortgage Loan and shall be equal to the
product of a rate equal to 0.00047% per annum (the “Asset Representations Reviewer Fee Rate”) and the
Stated Principal Balance of the Mortgage Loans and any REO Loans and shall be calculated in the same manner as interest is calculated
on such Mortgage Loans and REO Loans.


 


(b)          As
compensation for the performance of its duties hereunder, with respect to an individual Asset Review Trigger and the Mortgage Loans
that are Delinquent Loans and are subject to an Asset Review (for purposes of this Section 12.02(b), “Subject Loans”),
upon the


 



     -538-


     


    

 


completion of any Asset Review with respect to an individual Asset Review Trigger, the Asset Representations Reviewer
shall be paid a fee equal to the sum of: (i) $15,000 multiplied by the number of Subject Loans, plus (ii) $1,500 per Mortgaged
Property relating to the Subject Loans in excess of one Mortgaged Property per Subject Loan, plus (iii) $2,000 per Mortgaged Property
relating to a Subject Loan subject to a ground lease, plus (iv) $1,000 per Mortgaged Property relating to a Subject Loan subject
to a franchise agreement, hotel management agreement or hotel license agreement, subject, in the case of each of clauses (i)
through (iv), to adjustments on the basis of the year-end Consumer Price Index for All Urban Consumers, or other similar
index if the Consumer Price Index for All Urban Consumers is no longer calculated, for the year of the Closing Date and for the
year of the occurrence of the Asset Review (the “Asset Representations Reviewer Asset Review Fee”). The Asset
Representations Reviewer Asset Review Fee with respect to each Delinquent Loan shall be paid, in the first instance, by the related
Mortgage Loan Seller within forty-five (45) days of receipt by the related Mortgage Loan Seller of a written invoice from the Asset
Representations Reviewer. If the related Mortgage Loan Seller (x) is insolvent or (y) fails to pay such amount upon completion
of any Asset Review and within 90 days of receiving an invoice from the asset representations reviewer, such fee shall be paid
by the Trust following delivery by the Asset Representations Reviewer of evidence reasonably satisfactory to the Master Servicer
or the Special Servicer, as applicable, of such insolvency or failure to pay such amount; provided, however, that
a statement of non-payment by the Asset Representations Reviewer ninety (90) days after an itemized invoice is delivered by registered
mail to the address listed in this Agreement for the related Mortgage Loan Seller, or to such other address as shall be provided
by such Mortgage Loan Seller for delivery of notice in accordance with this Agreement, together with evidence of delivery or attempted
delivery of such invoice and reasonable follow up by phone or email, shall constitute satisfactory evidence delivered by the Asset
Representations Reviewer of such failure to pay such amount. Notwithstanding any payment of such fee by the Trust to the Asset
Representations Reviewer, such fee will remain an obligation of the related Mortgage Loan Seller and the Special Servicer shall
reasonably pursue remedies against such Mortgage Loan Seller to recover any such amounts to the extent paid by the Trust and the
costs of doing so shall be a cost of the Trust. If the Asset Representations Reviewer Asset Review Fee is paid by the Trust pursuant
to clause (y) above, the Trust shall be entitled to interest on such Asset Representations Reviewer Asset Review Fee at
the advance rate from the related Mortgage Loan Seller and the Special Servicer shall be entitled to an additional fee equal to
40.0% of such Asset Representations Reviewer Asset Review Fee from the related Mortgage Loan Seller upon recovery of such amount),
pursuant to Section 5 of the related Mortgage Loan Purchase Agreement.


 


(c)          Notwithstanding
the foregoing, the Asset Representations Reviewer Asset Review Fee with respect to a Delinquent Loan shall be included in the Purchase
Price for any Mortgage Loan that was the subject of a completed Asset Review and that is repurchased by a Mortgage Loan Seller,
and such portion of the Purchase Price received shall be used to reimburse the Trust for such fees paid to the Asset Representations
Reviewer pursuant to Section 12.02(b).


 


(d)          The
Asset Representations Reviewer shall be liable in accordance herewith only to the extent of the obligations specifically imposed
by this Agreement.


 


Section 12.03     Resignation
of the Asset Representations Reviewer.   The Asset Representations Reviewer may resign and be discharged from
its obligations hereunder by giving


 



     -539-


     


    

 


written notice thereof to the other parties to this Agreement and each Rating Agency. Upon
such notice of resignation, the Depositor shall promptly appoint a successor asset representations reviewer that is an Eligible
Asset Representations Reviewer. No resignation of the Asset Representations Reviewer shall be effective until a successor asset
representations reviewer that is an Eligible Asset Representations Reviewer has been appointed and accepted the appointment. If
no successor asset representations reviewer shall have been so appointed and have accepted appointment within 30 days after the
giving of such notice of resignation, the resigning Asset Representations Reviewer may petition any court of competent jurisdiction
for the appointment of a successor asset representations reviewer that is an Eligible Asset Representations Reviewer. The Asset
Representations Reviewer will bear all reasonable costs and expenses of each other party hereto and each Rating Agency in connection
with its resignation.


 


Section 12.04     Restrictions
of the Asset Representations Reviewer.   Neither the Asset Representations Reviewer nor any of its Affiliates
shall make any investment in any Class of Certificates; provided, however, that such prohibition shall not apply
to (i) riskless principal transactions effected by a broker dealer Affiliate of the Asset Representations Reviewer or (ii) investments
by an Affiliate of the Asset Representations Reviewer if the Asset Representations Reviewer and such Affiliate maintain policies
and procedures that (A) segregate personnel involved in the activities of the Asset Representations Reviewer under this Agreement
from personnel involved in such Affiliate’s investment activities and (B) prevent such Affiliate and its personnel from
gaining access to information regarding the Trust and the Asset Representations Reviewer and its personnel from gaining access
to such Affiliate’s information regarding its investment activities.


 


Section 12.05     Termination
of the Asset Representations Reviewer.  


 


(a)          An “Asset Representations
Reviewer Termination Event” means any one of the following events whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body:


 


(i)           any
failure by the Asset Representations Reviewer to observe or perform in any material respect any of its covenants or agreements
or the material breach of any of its representations or warranties under this Agreement, which failure shall continue unremedied
for a period of 30 days after the date on which written notice of such failure, requiring the same to be remedied, shall have been
given to the Asset Representations Reviewer by the Trustee or to the Asset Representations Reviewer and the Trustee by the Holders
of Certificates having at least 25% of the Pooled Voting Rights of all then-outstanding Certificates; provided that if such
failure is capable of being cured and the Asset Representations Reviewer certifies to the other parties to this Agreement that
it is diligently pursuing such cure, such 30 day period shall be extended by an additional 30 days;


 


(ii)          any
failure by the Asset Representations Reviewer to perform in any material respect any of its obligations hereunder in accordance
with the Asset Review Standard which failure shall continue unremedied for a period of 30 days after the date of


 



     -540-


     


    

 


written notice
of such failure, requiring the same to be remedied, is given to the Asset Representations Reviewer by any party to this Agreement;


 


(iii)         any
failure by the Asset Representations Reviewer to be an Eligible Asset Representations Reviewer, which failure shall continue unremedied
for a period of 30 days after the date of written notice of such failure, requiring the same to be remedied, is given to the Asset
Representations Reviewer by any party to this Agreement;


 


(iv)         a
decree or order of a court or agency or supervisory authority having jurisdiction in the premises in an involuntary case under
any present or future federal or state bankruptcy, insolvency or similar law for the appointment of a conservator or receiver or
liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding-up
or liquidation of its affairs, shall have been entered against the Asset Representations Reviewer, and such decree or order shall
have remained in force undischarged or unstayed for a period of 60 days;


 


(v)          the
Asset Representations Reviewer shall consent to the appointment of a conservator or receiver or liquidator or liquidation committee
in any insolvency, readjustment of debt, marshaling of assets and liabilities, voluntary liquidation, or similar proceedings of
or relating to the Asset Representations Reviewer or of or relating to all or substantially all of its property; or


 


(vi)       the
Asset Representations Reviewer shall admit in writing its inability to pay its debts generally as they become due, file a petition
to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors,
or voluntarily suspend payment of its obligations.


 


Upon receipt by the Certificate
Administrator (which shall be simultaneously delivered by the Certificate Administrator to the Asset Representations Reviewer)
of written notice of the occurrence of any Asset Representations Reviewer Termination Event, the Certificate Administrator shall
promptly provide written notice to all Pooled Certificateholders in accordance with the notice distribution procedures described
in Section 12.01(a), unless the Certificate Administrator has received written notice that such Asset Representations Reviewer
Termination Event has been remedied. If an Asset Representations Reviewer Termination Event shall occur then, and in each and every
such case, so long as such Asset Representations Reviewer Termination Event shall not have been remedied, either the Trustee (i)
may or (ii) upon the written direction of holders of Corresponding Certificates evidencing not less than 25% of the Pooled Voting
Rights of each Class of Pooled Regular Interests (other than the Class X Regular Interests) (without regard to the application
of any Cumulative Appraisal Reduction Amounts), the Trustee shall, terminate all of the rights and obligations of the Asset Representations
Reviewer under this Agreement, other than rights and obligations accrued prior to such termination (including the right to receive
all amounts accrued and owing to it under this Agreement) and other than indemnification rights (arising out of events occurring
prior to such termination), by notice in writing to the Asset Representations Reviewer. The Asset Representations Reviewer is required
to bear all reasonable costs and expenses of each other party to this Agreement in connection with its termination due to an Asset
Representations Reviewer Termination Event. Notwithstanding anything herein to the contrary, the Depositor


 



     -541-


     


    

 


and each Sponsor shall
have the right, but not the obligation, to notify the Certificate Administrator and the Trustee of any Asset Representations Reviewer
Termination Event of which it becomes aware.


 


(b)          Upon
(i) the written direction of the Pooled Certificateholders evidencing not less than 25% of the Pooled Voting Rights (without regard
to the application of any Cumulative Appraisal Reduction Amounts) requesting a vote to terminate and replace the Asset Representations
Reviewer with a proposed successor asset representations reviewer that is an Eligible Asset Representations Reviewer and (ii) payment
by such Holders to the Certificate Administrator of the reasonable fees and expenses to be incurred by the Certificate Administrator
in connection with administering such vote, the Certificate Administrator shall promptly provide written notice thereof to the
Asset Representations Reviewer and to all Pooled Certificateholders by (i) posting such notice on its internet website, and (ii)
mailing such notice to all Pooled Certificateholders at their addresses appearing in the Certificate Register and to the Asset
Representations Reviewer. Upon the written direction of the Pooled Certificateholders evidencing at least 75% of a Pooled Certificateholder
Quorum (without regard to the application of any Cumulative Appraisal Reduction Amounts), the Trustee shall terminate all of the
rights and obligations of the Asset Representations Reviewer under this Agreement (other than any rights or obligations that accrued
prior to the date of such termination and other than indemnification rights arising out of events occurring prior to such termination)
by notice in writing to the Asset Representations Reviewer. As between the Asset Representations Reviewer, on the one hand, and
the Pooled Certificateholders, on the other, the Pooled Certificateholders shall be entitled in their sole discretion to vote for
the termination or not vote for the termination of the Asset Representations Reviewer. In the event that the Pooled Certificateholders
entitled to at least 75% of a Pooled Certificateholder Quorum (without regard to the application of any Cumulative Appraisal Reduction
Amounts) elect to remove the Asset Representations Reviewer without cause and appoint a successor, the successor asset representations
reviewer will be responsible for all expenses necessary to effect the transfer of responsibilities from its predecessor.


 


(c)          On
or after the receipt by the Asset Representations Reviewer of written notice of termination, subject to this Section 12.05,
all of its authority and power under this Agreement shall be terminated and, without limitation, the terminated Asset Representations
Reviewer shall execute any and all documents and other instruments, and do or accomplish all other acts or things reasonably necessary
or appropriate to effect the purposes of such notice of termination. As soon as practicable, but in no event later than 15 Business
Days after (1) the Asset Representations Reviewer resigns pursuant to Section 12.03 of this Agreement or (2) the Trustee
delivers such written notice of termination to the Asset Representations Reviewer, the Trustee shall appoint a successor asset
representations reviewer that is an Eligible Asset Representations Reviewer. The Trustee shall provide written notice of the appointment
of an Asset Representations Reviewer to the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator,
the Directing Certificateholder, the Directing Holder and each Certificateholder within one Business Day of such appointment.


 


The Asset Representations
Reviewer shall be at all times an Eligible Asset Representations Reviewer and if the Asset Representations Reviewer ceases to be
an Eligible Asset Representations Reviewer, the Asset Representations Reviewer shall immediately notify


 



     -542-


     


    

 


the Master Servicer, the
Special Servicer, the Trustee, the Operating Advisor, the Certificate Administrator and the Directing Holder of such disqualification
and immediately resign under Section 12.03 of this Agreement and the Trustee shall appoint a successor asset representations
reviewer subject to and in accordance with this Section 12.05. Notwithstanding the foregoing, if the Trustee is unable to
find a successor asset representations reviewer within 30 days of the termination of the Asset Representations Reviewer, the Depositor
shall be permitted to find a replacement. The Trustee shall not be liable for any failure to identify and appoint a successor asset
representations reviewer for so long as the Trustee uses commercially reasonable efforts to conduct a search for a successor asset
representations reviewer and such failure is not a result of the Trustee’s negligence, bad faith or willful misconduct in
the performance of its obligations hereunder.


 


(d)          Upon
any termination of the Asset Representations Reviewer and appointment of a successor to the Asset Representations Reviewer, the
Trustee shall, as soon as possible, give written notice thereof to the Special Servicer, the Master Servicer, the Certificate Administrator
(who shall, as soon as possible, give written notice thereof to the Certificateholders), the Operating Advisor, the Sponsors, the
Depositor and, prior to the occurrence and continuance of a Consultation Termination Event, the Directing Holder and each Rating
Agency. In the event that the Asset Representations Reviewer is terminated, all of its rights and obligations under this Agreement
shall terminate, other than any rights or obligations that accrued prior to the date of such termination (including the right to
receive all amounts accrued and owing to it under this Agreement) and other than indemnification rights (arising out of events
occurring prior to such termination).

     -545-


     


    

 


Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as

(b)          This
Agreement may also be amended from time to time by the parties hereto with the consent of the Holders of Certificates of each Class
affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR Interest

consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Certificate Administrator may prescribe.


 


(f)           The
Trustee and the Certificate Administrator shall not be obligated to enter into any amendment pursuant to this Section 13.01

Certificates pursuant to Section 3.25).


 


(i)           To

appropriate locations promptly following the initial issuance of the Certificates to reflect the assignments made by the Mortgage
Loan Sellers to the Depositor (and the Trustee) and by the Depositor to the Trustee (copies of which shall be delivered by the
Depositor to the Certificate Administrator shall, at the expense of the Depositor (to the extent reasonable), no later than 10
days following the Closing Date), and the Certificate Administrator shall prepare and file continuation statements with respect
thereto, in each case in the six month period prior to every fifth anniversary of the date of the initial UCC Financing Statement.
The Depositor shall cooperate in a reasonable manner with the Certificate Administrator in the preparation and filing of such
continuation statements. This Section 13.07 shall constitute notice to the Certificate Administrator and the Trustee pursuant

Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,”
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-1
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-1
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.

Distributions
are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with
written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be
in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies

Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate

Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest,
the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect
the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests
constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions
of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class;
provided, however, that no such amendment shall:

                                         Holder; or



 


		(ii)	reduce
                                         the aforesaid percentage of Certificates of any Class the Holders of which are required

                                         as applicable; or

                                         of all Certificates of such Class then outstanding; or



 


		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise

                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided
                                         that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.

Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the

created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans.

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-2 Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”)
held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust
Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder
of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing
Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision
of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency.
Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-3, Class A-4, Class A-5, Class A-

the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,”
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-2
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-2
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.


 






    A-2-4


     


    

 


Distributions
are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with
written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be
in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies


 






    A-2-5


     


    

 


with
respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and
Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases
and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties
or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans
(to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing
Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of
the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the
Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein)
and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix)
any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the
Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular
Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other
than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts,
to the extent such interest belongs to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes

the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.

Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-3 Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held
in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust
Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder
of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing
Agreement and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision
of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency.
Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-4, Class A-5, Class A-SB, Class
X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F,

the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,”
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-3
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-3
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the


 






    A-3-4


     


    

 


account
of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided
the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise
(b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust
Subordinate Companion Loans required to be


 






    A-3-5


     


    

 


maintained
pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein);
(vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters
of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or
Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss
of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in
the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier
REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution
Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent
of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any
reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein);
(x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds
of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts
and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate

Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:

                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 





Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the



 






    A-3-10


     


    

 


effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under
the relevant provisions of the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-4 Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held
in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,”
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-4
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-4
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the


 






    A-4-4


     


    

 


account
of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided
the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise
(b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced

the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders
of Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR
Interest, the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would
adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate
Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the
Holders of Certificates of such Class; provided, however, that no such amendment shall:


 


		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage

                                         a Certificate of any class without the consent of the Holder of the Certificate or which

                                         Holder; or



 


		(ii)	reduce
                                         the aforesaid percentage of Certificates of any Class the Holders of which are required

                                         Holder or Holder of Loan-Specific Certificates, in any such case, without the consent
                                         of the Holders of all Certificates of such Class then-outstanding or such Companion Holders,
                                         as applicable; or

                                         of all Certificates of such Class then outstanding; or



 


		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the

                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided
                                         that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.

Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to
the Pooling and Servicing Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the
effect that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been
satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the
Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other
specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust
Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify
as a grantor trust under the relevant provisions of the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.


 


Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class A-5 Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held
in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate
Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate,
by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and
is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling
and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued
under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-

the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-5 Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class A-5 Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs.


 






     A-5-4


     


    

 


Distributions
are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with
written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be
in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate
Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests
of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies


 






     A-5-5


     


    

 


with
respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and
Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases
and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties
or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans
(to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing
Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of
the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the
Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein)
and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix)
any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the
Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular
Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other
than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts,
to the extent such interest belongs to the related Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.

Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any
agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee,

Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, or any
agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee,
the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

     A-5-9


     


    

 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing
of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a
Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion
Holder without the consent of such Companion Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any
Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion
Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such
Class then-outstanding or such Companion Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates
without the consent of the Holders of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage
Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without
the consent of such Mortgage Loan Seller; or



 


		(v)	amend the Servicing Standard without the consent of 100%
of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to
Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of
the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.



 






     A-5-10


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the


 


 






     A-5-11


     


    

Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class A-SB Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held
in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate
Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate,
by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and
is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling
and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued
under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5,

Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class A-SB Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-SB
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class A-SB Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs.


 






     A-6-3


     


    

 


Distributions
are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with
written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be
in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate
Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests
of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies


 






     A-6-4


     


    

 


with
respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and
Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases
and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties
or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans
(to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing
Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of

Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution

     A-6-8


     


    




 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing
of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a
Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion
Holder without the consent of such Companion Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any
Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion
Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such
Class then-outstanding or such Companion Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates
without the consent of the Holders of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage
Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without
the consent of such Mortgage Loan Seller; or



 


		(v)	amend the Servicing Standard without the consent of
100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to
Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of
the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.



 






     A-6-9


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the

Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

IN WITNESS WHEREOF,
the Certificate Administrator has caused this Class A-SB Certificate to be duly executed.

in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate
Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate,
by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and
is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling

Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class X-A Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-A Certificates for
such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be
entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class X-A Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the


 






     A-7-4


     


    

 


account
of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided
the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise
(b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the

not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same

of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to

any
of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is

		(vi)	to revise or add any other provisions with respect to
matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required
action shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance
of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a
Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel,

as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the
provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances

Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan,
as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class,

     A-7-8

the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization
transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision
related to the risk retention requirements in the event of such repeal.



 


Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller

     A-7-9


     


    

 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing
of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a
Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion
Holder without the consent of such Companion Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any
Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion
Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such
Class then-outstanding or such Companion Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates
without the consent of the Holders of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage
Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without
the consent of such Mortgage Loan Seller; or



 


		(v)	amend the Servicing Standard without the consent of 100%
of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to
Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of
the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.



 






     A-7-10


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the


 






     A-7-11


     


    

 


Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

IN WITNESS WHEREOF,
the Certificate Administrator has caused this Class X-A Certificate to be duly executed.

of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-B Certificates for
such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be
entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class X-B Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor,


 






     A-8-4


     


    

 


if
such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days
prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate
Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests
of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the


 






     A-8-5


     


    

 


extent
of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s
interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security
for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii)
all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest
therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC
Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts,
the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale
Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s
interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent
of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement
(to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan
REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.

The Pooling and Servicing
Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor,

or the Companion Holders:


 


		(i)	to correct any defect or ambiguity in the Pooling and

related non-offered certificates) with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct
or supplement any of its provisions which may be inconsistent with any other provisions therein or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the
Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall
in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect
in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest,
a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense
of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to
such amendment;

to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the

to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of
the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR

of Counsel, cause the Trust, any Trust REMIC or 



 






     A-8-7


     


    

 


any
of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is

		(vi)	to revise or add any other provisions with respect to
matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that the required

of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a
Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel,
at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating
Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will
not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities,
if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency
Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing
Agreement);



 


		(vii)	to amend or supplement any provision of the Pooling and
Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by each
Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered
satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant
to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely
affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a
VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) not consenting to such amendment or supplement,
as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the
provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances
and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control
Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan,
as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class,
the Directing Holder,



 






     A-8-8


     


    

 


determine
that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such
industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the
Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each
Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities,
the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or
qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in
the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section
3.25 of the Pooling and Servicing Agreement);


 


		(ix)	to modify the procedures of the Pooling and Servicing
Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely
affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of
a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel
or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates;
and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information
Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing
Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website; to modify,
eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply with
the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or



 


		(x)	to modify, eliminate or add to any of its provisions in
the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization
transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision
related to the risk retention requirements in the event of such repeal.



 


Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 






     A-8-9


     


    

 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing
of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a
Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion
Holder without the consent of such Companion Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any
Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion
Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such
Class then-outstanding or such Companion Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates
without the consent of the Holders of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage
Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without
the consent of such Mortgage Loan Seller; or



 


		(v)	amend the Servicing Standard without the consent of 100%
of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to
Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of
the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.



 






     A-8-10


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the


 






     A-8-11


     


    

 


Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.


 






     A-8-12


     


    

 


IN WITNESS WHEREOF,
the Certificate Administrator has caused this Class X-B Certificate to be duly executed.

The
Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and
multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion
Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage
Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined
below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of
the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this
Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to
the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class
A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class D, Class E,

Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-E Certificates for
such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related


 


 






     A-9-4


     


    

 


Distribution
Date to the extent provided in the Pooling and Servicing Agreement. The “Interest Accrual Period” with respect
to any Distribution Date and with respect to the Class X-E Certificates is the calendar month immediately preceding the month
in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate

Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit,
indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate

as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights
and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the

foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and
any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any

or the Companion Holders:


 






     A-9-7


     


    

 


		(i)	to correct any defect or ambiguity in the Pooling and
Servicing Agreement;



 


		(ii)	to cause the provisions in the Pooling and Servicing Agreement

or supplement any of its provisions which may be inconsistent with any other provisions therein or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the
Collection Account, the Distribution Accounts or any REO Account; provided that (a) the P&I Advance Date shall
in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely affect
in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest,
a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense
of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to
such amendment;

and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the
Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding, or
to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the

to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of
the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR

not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities,
if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency
Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing
Agreement);



 


		(vii)	to amend or supplement any provision of the Pooling and
Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by each

to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely
affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a
VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest) not consenting to such amendment or supplement,
as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the
provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances

Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan,
as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class,
the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed,
in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as
a REMIC or the status of the Grantor Trust



 






     A-9-9


     


    

 


as
a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has
delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating
agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current
ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency
Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing
Agreement);


 


		(ix)	to modify the procedures of the Pooling and Servicing
Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely
affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of
a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel
or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates;
and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information
Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing

transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision
related to the risk retention requirements in the event of such repeal.



 


Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR


 






     A-9-10


     


    

 


Interest
or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing
of, payments received on the Mortgage Loans or the Trust Subordinate Companion Loans that are required to be distributed on a
Certificate of any class without the consent of the Holder of the Certificate or which are required to be distributed to a Companion
Holder without the consent of such Companion Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any
Class the Holders of which are required to consent to any such amendment or remove the requirement to obtain consent of any Companion
Holder or Holder of Loan-Specific Certificates, in any such case, without the consent of the Holders of all Certificates of such
Class then-outstanding or such Companion Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates
without the consent of the Holders of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage
Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without
the consent of such Mortgage Loan Seller; or



 


		(v)	amend the Servicing Standard without the consent of 100%
of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to
Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of
the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






     A-9-11


     


    

 


effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under
the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class A-S Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held
in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate
Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate,
by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and
is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling
and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued

the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-S Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class A-S Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the


 






    A-10-4


     


    

 


account
of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided
the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise
(b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate
Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests
of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be

maintained
pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein);
(vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters
of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related Mortgage Loans or
Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss
of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in

REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution
Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent
of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any
reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein);
(x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds
of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts
and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.

    A-10-7


     


    

 


any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that

Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment

provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the provisions of Sections
3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed

requirements in the event of such repeal.



 


Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 






    A-10-9


     


    

 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 






    A-10-10


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the


 






    A-10-11


     


    

 


Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class A-S Certificate to be duly executed.

the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class B Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class B Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs.


 






    A-11-4


     


    

 


Distributions
are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with
written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be
in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate
Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests
of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies


 






    A-11-5


     


    

 


with
respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and
Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases
and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties
or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans
(to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing
Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of
the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the
Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein)
and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix)
any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the
Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular
Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other
than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts,
to the extent such interest belongs to the related Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.

    A-11-9


     


    

 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations

Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 






    A-11-10


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the


 






    A-11-11


     


    

 


Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor

the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class C Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class C Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the


 






    A-12-4


     


    

 


account
of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided
the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise
(b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate
Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests
of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with
respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be 


 






    A-12-5


     


    

 


maintained pursuant to the Pooling and
Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases
and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties
or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans

Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein)
and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix)
any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the
Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular
Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other
than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts,
to the extent such interest belongs to the related Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.

Class.

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the

of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 






    A-12-10


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the

Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class D Certificates. The Trust Fund, described more
fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties and
subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held in trust
by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate
Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate,
by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and
is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling
and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued
under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class
X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class E, Class F, Class NR, Class V1-A, Class V1-B,
Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class
UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC,
Class V2-STN, Class R and Class Z Certificates (together with the Class D Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class D Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate


 






    A-13-4


     


    

 


may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class D Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 






    A-13-5

of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified

interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related

This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee,


 






    A-13-6


     


    

 


the
Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating

Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any notice to the contrary.

the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders
or the Companion Holders:


 


		(i)	to correct any defect or ambiguity in the Pooling and Servicing Agreement;



 


		(ii)	to cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with
or in furtherance of the statements made in the Prospectus (or in an offering document for any related non-offered certificates)
with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts
or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior
to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced
by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;



 


		(iv)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under
the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition
of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have
received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary
or desirable to maintain such qualification or to avoid or minimize the risk of the 



 






    A-13-7


     


    

 


imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,

is a Disqualified Organization or a Non-U.S. Tax Person;



 


		(vi)	to revise or add any other provisions with respect to matters or questions arising under the Pooling
and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material
respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L
Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and
confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of
its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a 



 






    A-13-8


     


    

 


Standard Highline VRR
Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;


 


		(viii)	to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with
respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master
Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect
to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder,
the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);



 


		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5
of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any
Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard
Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of
Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice
to the Certificate Administrator’s Website;



 


		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or



 


		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or 



 






    A-13-9


     


    

 


repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.


 


Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without
the consent of 100% of the



 






    A-13-10


     


    

 


Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.


 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master


 






    A-13-11


     


    

 


Servicer,
to exchange all of its Certificates (other than the Class Z and Class R Certificates) together with the payment or deemed payment
of the Termination Purchase Amount for all of the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property
remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class E Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
and subordinate interests in two subordinate companion loans (the “Trust Subordinate Companion Loans”) held
in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate
Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate,
by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and
is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling
and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued
under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class
X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class F, Class NR, Class V1-A, Class V1-B,
Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C, Class UES-D, Class
UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class V1-STNA, Class V1-STNC,
Class V2-STN, Class R and Class Z Certificates (together with the Class E Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class E Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 






    A-14-5


     


    

 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class E Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more
specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the


 






    A-14-6


     


    

 


Trust
Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan,
the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments
on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with
respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent
of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced
Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent
of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s
and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion
Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the
Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s
interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security
for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii)
all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest
therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC
Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts,
the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale
Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s
interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent
of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement
(to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan
REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any

requirements in the event of such repeal.



 


Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any


 






    A-14-11


     


    

 


Mortgage
Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third
party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially
and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be 



 






    A-14-12


     


    

 


considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.


 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to


 






    A-14-13


     


    

 


Certificateholders
as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the
Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a
sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created
by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants
of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class E Certificate to be duly executed.

of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this
Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to
the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3,

the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount of principal and interest then distributable, if any, allocable to the Class F Certificates for such Distribution
Date, all as more fully described in the Pooling and Servicing Agreement.


 






    A-15-5


     


    

 


Interest accrued on this Certificate
during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will
be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class F Certificates is the calendar month
immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited
in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically
set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the


 



    A-15-6


     


    

 


Trust Subordinate Companion

related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s
interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related
Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited
in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on
deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest
Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account
(to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein),
including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s
interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred
to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and
(xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does not
purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the
interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities
of the Certificate Administrator and Trustee.


 


As provided in the Pooling
and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer
of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any


 



    A-15-7


     


    

 


Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.


 


The Pooling and Servicing
Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor,
the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders
or the Companion Holders:


 


		(i)	to correct any defect or ambiguity in the Pooling and Servicing Agreement;



 


		(ii)	to cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with
or in furtherance of the statements made in the Prospectus (or in an offering document for any related non-offered certificates)
with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts
or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to
the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced
by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;



 


		(iv)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under
the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition
of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have
received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary
or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest, a Y&L Towers 



 






    A-15-8


     


    

 


VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided

or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;



 


		(vi)	to revise or add any other provisions with respect to matters or questions arising under the Pooling
and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material
respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L
Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and
confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of
its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the provisions of Sections
3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed
Reimbursement Amounts) if (a) the



 



    A-15-10


     


    

 


Depositor, the Master
Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect
to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder,
the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);


 


		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule
17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests
of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest
or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt
of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice
to the Certificate Administrator’s Website;



 


		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or



 


		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.



 


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any


 



    A-15-11


     


    

 


Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be 



 






    A-15-12


     


    

 


considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.


 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created by
the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to
make payments to


 



    A-15-13


     


    

 


Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.


 


Unless the certificate of
authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class F Certificate to be duly executed.

This certifies that [           ] is
the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to
the Class NR Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by
first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust
Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement
(as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions
of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of this
Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to
the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3,
Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class
V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class UES-A, Class UES-B, Class UES-C,
Class UES-D, Class UES-X, Class STN-A, Class STN-B, Class STN-X, Class STN-C, Class V1-UESA, Class V1-UESD, Class V2-UES, Class
V1-STNA, Class V1-STNC, Class V2-STN, Class R and Class Z Certificates (together with the Class NR Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount of principal and interest then distributable, if any, allocable to the Class NR Certificates for such Distribution
Date, all as more fully described in the Pooling and Servicing Agreement.


 






    A-16-5


     


    

 


Interest accrued on this Certificate
during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will
be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class NR Certificates is the calendar month
immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited
in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically
set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the


 



    A-16-6


     


    

 


Trust Subordinate Companion

related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s
interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related
Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited
in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on
deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest
Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account
(to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein),
including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s
interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred
to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and
(xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does not
purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the
interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities
of the Certificate Administrator and Trustee.


 


As provided in the Pooling
and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer
of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the

or the Companion Holders:


 


		(i)	to correct any defect or ambiguity in the Pooling and Servicing Agreement;

(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced
by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

is a Disqualified Organization or a Non-U.S. Tax Person;



 


		(vi)	to revise or add any other provisions with respect to matters or questions arising under the Pooling

confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of
its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation

Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency

(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the provisions of Sections

Depositor, the Master
Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect
to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder,
the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation

satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);


 


		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule
17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests
of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest
or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt
of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice
to the Certificate Administrator’s Website;



 


		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent

to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.



 


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any


 



    A-16-11


     


    

 


Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be 



 






    A-16-12


     


    

 


considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.


 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and

Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.


 


Unless the certificate of

Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation

Class V1-STNA, Class V1-STNC, Class V2-STN and Class Z Certificates (together with the Class R Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
a “residual interest” in four “real estate mortgage investment conduits,” as those terms are defined, respectively,
in Sections 860G(a)(2) and 860D of the Internal Revenue Code of 1986, as amended.


 


Each Holder of this Certificate,
by acceptance hereof, agrees to treat, and take no action inconsistent with the treatment of, this Certificate in accordance with
the preceding sentence for purposes of federal income taxes, state and local income and franchise taxes and other taxes imposed
on or measured by income. The Holder of the largest Percentage Interest in the Class R Certificates shall be the “tax matters
person” pursuant to Treasury Regulations Section 1.860F 4(d) and “partnership representative” (within the meaning
of Section 6223 of the Code, to the extent such provision is applicable to the Trust REMICs) for each Trust REMIC, and the Certificate
Administrator is hereby irrevocably designated and shall serve as attorney in fact and agent for any such Person that is the “tax
matters person” or “partnership representative”.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of the aggregate amount,
if any, allocable to the Class R


 



    A-18-4


     


    

 


Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing
Agreement.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited
in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically
set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion
Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the
related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due


 



    A-18-5


     


    

 


after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s
interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related
Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited
in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on
deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest
Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account
(to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein),
including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s
interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred
to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and
(xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does not
purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the
interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities
of the Certificate Administrator and Trustee.


 


As provided in the Pooling
and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer
of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of

Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment

confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of
its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation

provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the provisions of Sections

of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest
or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt
of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice
to the Certificate Administrator’s Website;



 


		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or



 


		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.



 


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR


 



    A-18-10


     


    

 


Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the


 



    A-18-11


     


    

 


effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created by
the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to
make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

the Class Z Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein
as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
a beneficial ownership of Excess Interest and the Excess Interest Distribution Account. Each Holder of this Certificate, by acceptance
hereof, agrees to treat, and take no action inconsistent with the treatment of, this Certificate in accordance with the preceding
sentence for purposes of federal income taxes, state and local income and franchise taxes and other taxes imposed on or measured
by income.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount, if any, allocable to the Class Z Certificates for such Distribution Date, all as more fully described in
the Pooling and Servicing Agreement.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions


 



    A-18-3


     


    

 


no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited
in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage Loans, as more specifically
set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion
Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the
related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the Trust’s
interest therein); (vi) any Assignment of Leases and any security agreements


 



    A-18-4


     


    

 


(to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related
Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited
in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on
deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest
Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account
(to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein),
including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s
interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred
to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and
(xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does not
purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the
interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities
of the Certificate Administrator and Trustee.


 


As provided in the Pooling
and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer
of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.


 


The Pooling and Servicing

the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders
or the Companion Holders:


 






    A-18-5


     


    

 


		(i)	to correct any defect or ambiguity in the Pooling and Servicing Agreement;



 


		(ii)	to cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with
or in furtherance of the statements made in the Prospectus (or in an offering document for any related non-offered certificates)
with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts
or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to
the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced
by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;



 


		(iv)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under
the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition
of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have
received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary
or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;



 


		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided
the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC
or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L
Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and
confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of
its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the provisions of Sections
3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed
Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event
has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing
Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder,
determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform
to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status
of the Grantor Trust



 






    A-18-7


     


    

 


as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);


 


		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule
17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests
of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest
or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt
of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice
to the Certificate Administrator’s Website;



 


		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or



 


		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.



 


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR


 



    A-18-8


     


    

 


Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the


 



    A-18-9


     


    

 


effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created by
the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to
make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

This
certifies that [              ] is the registered
owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class V1-A
Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens
on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate
Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and
the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement
(as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions
of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of
this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this


 






    A-19-3


     


    

 


Certificate shall be superseded
to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2,
Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D,

Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment
conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986,
as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-A
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-A
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the


 






    A-19-4


     


    

 


close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO


 






    A-19-5


     


    

 


Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust
Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s
interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion
Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest
Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to
the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate
Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent

Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest,

                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided

                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate

Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of

This

owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class V1-B
Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens
on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the “Trust Subordinate
Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and
the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement
(as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions
of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of
this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded
to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2,
Class A-3, Class A-4, Class A-5,

Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment
conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986,
as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-B
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-B
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs.


 






    A-20-4


     


    

 


Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies


 






    A-20-5


     


    

 


with respect to the Mortgage Loans and the Trust
Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s
interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion
Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest
Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to
the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate
Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes

the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar

Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years

of St. James, living on the date hereof.


 


Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,”
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-D
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-D


 






    A-21-4


     


    

 


Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

                                         of the Holders of all Certificates of such Class then-outstanding or such Companion Holders,

                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise

                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided
                                         that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






    A-21-11


     


    

 


effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

subordinate companion loans (the “Trust Subordinate

the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling and Servicing Agreement
(as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions
of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any provision of
this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall be superseded
to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2,

Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment
conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986,
as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-E
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-E


 






    A-22-5


     


    

 


Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due


 






    A-22-6


     


    

 


after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property

the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






    A-22-12


     


    

 


effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

subordinate
companion loans (the “Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the
Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced,
pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance
hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event
that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement,
such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and
Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E,

(together with the Class V1-F Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents (i) beneficial ownership of multiple “regular interests” in a “real estate mortgage investment
conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986,
as amended and (ii) a beneficial interest in the Excess Interest and proceeds thereof in the Excess Interest Distribution Account.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator
under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
V1-F Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest


 






    A-23-5 


     


    

 


Accrual Period” with respect to any Distribution Date and with respect to the Class V1-F Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or


 






    A-23-6 


     


    

 


collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust
Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s
interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion
Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest
Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to
the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate
Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate

                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided
                                         that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






    A-23-12 


     


    

 


effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

(together with the Class V1-Z Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
V1-Z Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-Z Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the


 






    A-24-4 


     


    

 


close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.

Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.

payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing

(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent

the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs

Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.

Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the

Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.


 


Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes

the Mortgage Loans or the Trust Subordinate Companion Loans.

Trustee and serviced by the
Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced,
pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance
hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event
that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement,
such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and
Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E,

(together with the Class V2-A Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of multiple “regular interests” in a “real estate mortgage investment
conduit,” as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986,
as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
V2-A Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this
Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest


 






    A-25-5 


     


    

 


Accrual Period” with respect to any Distribution Date and with respect to the Class V2-A Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject

effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

Trustee and serviced by the
Master Servicer. The Trust Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced,
pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance
hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event
that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing Agreement,
such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling and
Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E,
Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F,

(together with the Class V2-Z Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
V2-Z Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this
Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V2-Z Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 






    A-22-4 


     


    

 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or


 






    A-22-5 


     


    

 


the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust
Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s
interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion
Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest
Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to
the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate
Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).


 


This

Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.

Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate

                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided

                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the

			related
Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.




 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation,


 






    A-22-11 


     


    

 


any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.


 


Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans.

and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class UES-A Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on this
Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if
any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class UES-A Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other
than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the
Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities


 






     A-22-4


    


    

 


therefor,
if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days
prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited
in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate
Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.

and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing

related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified

interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired

interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

extent
of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s
interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security

the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale

interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent
of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement

not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.

Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.

which may be inconsistent with any other provisions therein or to correct any error;

(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced

or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action

Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to

or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and
confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of
its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

Mortgage

party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially
and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)

or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans

Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations

                                                                                             action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion
                                                                                             Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be 

                                                                                




  



     A-22-10


    


    

 





considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.


 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to


 






     A-22-11


    


    

 


Certificateholders
as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the
Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a
sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created
by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants
of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

(together with the Class UES-B Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,”
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
UES-B Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class UES-B Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds


 






     A-26-4


     

    

  


to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L
Towers Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust
Subordinate Companion Loans required to be


 






     A-26-5


     

    

 


maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s
interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion
Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest
Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to
the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate
Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.

Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate

whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.

of any of the Certificateholders or the Companion Holders:

Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of

of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class;
provided, however, that no such amendment shall:

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided
                                         that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be 



 



     A-26-10


     

    

  


considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.


 





Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to


 






     A-26-11


     

    

 


Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.


 


Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans.

Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents beneficial
ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined,
respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount of principal and interest then distributable, if any, allocable to the Class UES-C Certificates for such Distribution
Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on this Certificate
during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will
be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class UES-C Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities


 






    A-26-4 


     


    

 


therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed to
any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited in
right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate
Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling and
Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion
Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the
related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the


 






    A-26-5 


     


    

 


extent of the Trust’s
interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related
Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited
in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on
deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest
Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account
(to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein),
including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s
interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred
to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and
(xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does not purport
to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests,
rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of
the Certificate Administrator and Trustee.


 


As provided in the Pooling and
Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer
of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.


 


Prior to due presentation of
this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of

Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.

may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset
Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or
the Companion Holders:

(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced

or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment

Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;



 


		(viii)	to modify the provisions

			 Depositor, the Master
Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect
to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder,
the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule
17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests
of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest
or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt
of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s

or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.



 


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any


 






    A-26-9 


     


    

 


Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the
same manner as any Rating Agency Confirmation may be



 






    A-26-10 


     


    

 


			 considered satisfied with respect to the Certificates pursuant to Section
3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder
of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created by
the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to
make payments to


 






    A-26-11 


     


    

 


Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.


 


Unless the certificate of
authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued pursuant
to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents beneficial
ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined,
respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount of principal and interest then distributable, if any, allocable to the Class UES-D Certificates for such Distribution
Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on this Certificate
during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will
be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class UES-D Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities


 






    A-26-5 


     


    

 


therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed to
any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited in
right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate
Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling and
Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion
Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the
related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the


 






    A-26-6 


     


    

 


extent of the Trust’s
interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related
Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited
in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on
deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest
Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account
(to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein),
including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s
interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred
to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and
(xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does not purport
to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests,
rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of
the Certificate Administrator and Trustee.


 


As provided in the Pooling and
Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer
of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.


 


Prior to due presentation of
this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.

Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or
the Companion Holders:


 






    A-26-7 


     


    

 


		(i)	to correct any defect or ambiguity in the Pooling and Servicing Agreement;

the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced

any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;

		(vi)	to revise or add any other provisions with respect to matters or questions arising under the Pooling

Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and

its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the

Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

			Depositor, the Master

to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder,
the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation

or a Standard Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt

requirements for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment
or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.





  


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any


 






    A-26-10 


     


    

 


Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be 



 






    A-26-11 


     


    

 


			considered satisfied with respect
to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor
Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created by
the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to
make payments to


 






    A-26-12 


     


    

 


Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.


 


Unless the certificate of
authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued pursuant
to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents beneficial
ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined,
respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount of interest then distributable, if any, allocable to the Class UES-X Certificates for such Distribution Date,
all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on this Certificate
during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will
be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class UES-X Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities


 






    A-26-4 


     


    

 


therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed to
any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited in
right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate
Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling and
Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion
Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the
related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the 


 






    A-26-5 


     


    

 


extent of the
Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the
Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as
additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s
interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s
interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust
Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest
Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s
interest therein) and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x)
the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the

rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of
the Certificate Administrator and Trustee.


 


As provided in the Pooling and
Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer

Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any

the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation

Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s

requirements in the event of such repeal.



 


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any


 






    A-26-9 


     


    

 


Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be 



 






    A-26-10 


     


    

 


			considered satisfied with respect
to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor
Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which

(together with the Class STN-A Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,”
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
STN-A Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class STN-A Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities


 






    A-26-4 


     


    

 


therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard
Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust
Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the


 






    A-26-5 


     


    

 


extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s
interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion
Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest
Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to
the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate
Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:

Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any

Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest,
the Y&L Towers VRR Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect
the rights of such Certificateholders) evidencing in the aggregate not less than a majority of the aggregate Percentage Interests
constituting the Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions
of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class;
provided, however, that no such amendment shall:


 


		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage

                                         a Certificate of any class without the consent of the Holder of the Certificate or which
                                         are required to be distributed to a Companion Holder without the consent of such Companion
                                         Holder; or



 


		(ii)	reduce
                                         the aforesaid percentage of Certificates of any Class the Holders of which are required

                                         as applicable; or



 


		(iii)	adversely

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the
                                         Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or



 


		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be



 






    A-26-10 


     


    

 


 considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.


 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to


 






    A-26-11 


     


    

 


Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.


 


Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class STN-A Certificate to be duly executed.

referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital
Asset Management LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,”
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates, the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate
in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
STN-B Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class STN-B Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities


 






    A-26-4 


     


    

 


therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(l) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(l) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard
Highline Trust Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and
the Trust Subordinate Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced
Whole Loan, the interests of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled
payments on or collections in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date
(or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to
the extent of the Trust’s interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing
a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property
(to the extent of the Trust’s interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate
Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust
Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the


 






    A-26-5 


     


    

 


extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s
interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion
Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest
Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein) and any REO Account (to
the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate
Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).

Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender

the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.

                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise

                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be



 






    A-26-10 


     


    

 


 considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.


 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate
Companion Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination
of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which
the aggregate Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO
Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes
of this calculation, if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still
an asset of the Trust, then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of
Mortgage Loans and Trust Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans
and Trust Subordinate Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans, the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms
of the Pooling and Servicing Agreement.


 


The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to


 






    A-26-11 


     


    

 


Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.


 


Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class STN-B Certificate to be duly executed.

Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class STN-X Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on this
Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if
any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class STN-X Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other
than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the
Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities

therefor,
if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business Days
prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.

interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s

of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s
interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security

interest therein), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent
of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement

the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any

(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced

Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and
confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of
its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

Mortgage
Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third
party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially
and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans

Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations

                                                                                             or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such
                                                                                             action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion

considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.


 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to


 






     A-26-11


    


    

 


Certificateholders
as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate Balances of all the
Certificates to zero (including, without limitation, any such final payment resulting from a termination of the Trust due to a
sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will the Trust created
by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants
of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

This Certificate is issued pursuant
to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents beneficial
ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms are defined,
respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount of principal and interest then distributable, if any, allocable to the Class STN-C Certificates for such Distribution
Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on this Certificate
during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will
be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class STN-C Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder provided the Certificate Administrator with written wiring


 






    A-26-4


     


    

 


instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed to
any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.

Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing

related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified

interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired

interest therein); (vi) any Assignment of Leases and any security agreements

This Certificate does not purport
to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the interests,
rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities of
the Certificate Administrator and Trustee.


 


As provided in the Pooling and
Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer

this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any

the Holder of a majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation

requirements in the event of such repeal.



 


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any


 






    A-26-9


     


    

 


Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be 



 






    A-26-10


     


    

 





		 	considered satisfied with
respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related
Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.


 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created by
the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to
make payments to


 






    A-26-11


     


    

 


Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.


 


Unless the certificate of
authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as
those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-UESA Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on this Certificate
during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will
be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class V1-UESA Certificates is the
calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities
therefor,


 






    A-26-4


     


    

 


if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited
in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate
Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing

related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified

interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired

interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the

extent of the Trust’s
interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related
Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited

the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest
Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account

including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s
interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred

(xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does not

interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities
of the Certificate Administrator and Trustee.


 


As provided in the Pooling
and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer

Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the


 






    A-26-10


     


    

 


effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created by
the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to
make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

This certifies that [              ]
is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class V1-UESD Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans
secured by first liens on commercial and multifamily properties and subordinate interests in two subordinate companion loans (the
“Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust
Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,

Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of a “regular interest” in a “real estate mortgage investment conduit,” as those terms
are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of
the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-UESD Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on this Certificate
during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate, if any, will
be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class V1-UESD Certificates is the
calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the close of business on the last Business Day of the
month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a) by wire
transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities
therefor,


 






    A-26-5


     


    

 


if such Certificateholder provided the Certificate Administrator with written wiring instructions no less than five Business
Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate Register. The
final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate
at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of such final
distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is limited
in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate
Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate Companion
Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the
related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the


 






    A-26-6


     


    

 


extent of the Trust’s
interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s interest therein);
(vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security for any related
Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited
in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on
deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest
Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account
(to the extent of the Trust’s interest therein) and any REO Account (to the extent of the Trust’s interest therein),
including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s
interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred
to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and
(xiii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This Certificate does not
purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for the
interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and immunities
of the Certificate Administrator and Trustee.


 


As provided in the Pooling
and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer
of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any
notice to the contrary.


 


The Pooling and Servicing
Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor,
the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders
or the Companion Holders:

		(ii)	to cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with
or in furtherance of the statements made in the Prospectus (or in an offering document for any related non-offered certificates)
with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts
or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior
to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR
Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced
by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;



 


		(iv)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent

of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have
received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary
or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR Interest), or Companion Holder;



 


		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided
the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC
or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L
Towers VRR Interest or a Standard Highline VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and
confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of
its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest, a Y&L Towers VRR Interest or a Standard Highline VRR

Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing
Holder or, in the case of the Directing Certificateholder, the Holder of a majority of the Controlling Class, the Directing Holder,

such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);


 


		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5
of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any
Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest, a Y&L Towers VRR Interest or a Standard
Highline VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of
Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,

requirements in the event of such repeal.



 


Notwithstanding the foregoing,
no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller
as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B)
may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR

Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 


Notwithstanding the foregoing,
none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the
Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement without
having first received an Opinion of Counsel (at the Trust’s expense) to the


 






    A-26-11


     


    

 


effect that such amendment is permitted under
the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the majority
of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in that order
of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate Administrator
and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans (and all property
acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the
then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of
the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by the Trust is less than 1.0%
of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if such right is being
exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust, then such Mortgage Loan
will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate Companion Loans as of
the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date on which
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class B and
Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created by
the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to
make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of
the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

“Trust Subordinate Companion Loans”) held in trust by the Trustee and serviced by the Master Servicer. The Trust
Fund was created, and the Mortgage Loans and the Trust Subordinate Companion Loans are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the

Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as
those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V2-UES Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class V2-UES Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs.


 






    A-26-5


     


    

 


Distributions
are required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with
written wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be
in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Y&L Towers Trust Subordinate
Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate

of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies


 






    A-26-6


     


    

 


with
respect to the Mortgage Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and
Servicing Agreement and any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases
and any security agreements (to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties
or lease enhancement policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans
(to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss of Value Reserve Fund and the Servicing
Accounts (to the extent of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of
the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the
Trust Subordinate Companion Loan REMIC Distribution Accounts, the Regular Interest Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest therein)
and any REO Account (to the extent of the Trust’s interest therein), including any reinvestment income, as applicable; (ix)
any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the
Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular
Interests; (xii) the Trust Subordinate Companion Loan REMIC Regular Interests; and (xiii) the proceeds of the foregoing (other
than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts,
to the extent such interest belongs to the related Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.

of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate

    A-26-10


     


    

 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR
Interest or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 






    A-26-11


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the


 






    A-26-12


     


    

 


Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as
those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-STNA Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class V1-STNA Certificates is the
calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the


 






    A-26-4


     


    

 


account
of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided
the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise
(b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard Highline Trust
Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate
Companion Loans, together with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests
of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special Servicer’s, the Certificate Administrator’s and the
Trustee’s rights under the insurance policies with respect to the Mortgage Loans and the Trust Subordinate Companion Loans
required to be

requirements in the event of such repeal.



 


Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR


 






    A-26-9


     


    

 


Interest
or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






    A-26-10


     


    

 


effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under
the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation

if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class V1-STNC Certificates is the
calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the


 






     A-26-4


     


    

 


account
of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder provided
the Certificate Administrator with written wiring instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise
(b) by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.

requirements in the event of such repeal.



 


Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest, the Y&L Towers VRR


 






     A-26-9


     


    

 


Interest
or the Standard Highline VRR Interest to the extent any such amendment would adversely affect the rights of such Certificateholders)
evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to any such amendment or remove the requirement to obtain consent of any Companion Holder or Holder of Loan-Specific
Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or



 


		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






     A-26-10


     


    

 


effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under
the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Park Bridge Lender Services LLC, as Operating Advisor
and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and CWCapital Asset Management LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the
Pooling and Servicing Agreement.


 


This Certificate represents
beneficial ownership of multiple “regular interests” in a “real estate mortgage investment conduit,” as
those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.


 


The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
the Mortgage Loans or the Trust Subordinate Companion Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V2-STN Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class V2-STN Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business


  






     A-26-4


     


    

 


Day
of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made (a)
by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.


 


Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(l)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(l) of the Pooling and Servicing
Agreement.


 


This Certificate is
limited in right of payment to, among other things, certain collections and recoveries in respect of the Standard Highline Trust
Subordinate Companion Loan, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan) and the Trust Subordinate

of the related Serviced Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans and the Trust Subordinate Companion Loans due after the Cut-off Date (or with respect to a Qualified
Substitute Mortgage Loan, the Due Date in the month of substitution); (iii) any REO Property (to the extent of the Trust’s
interest therein) or the Trust’s beneficial interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired
under the related Non-Serviced PSA; (iv) all revenues received in respect of any REO Property (to the extent of the Trust’s
interest therein); (v) the Master Servicer’s, the Special

Loans and the Trust Subordinate Companion Loans required to be maintained pursuant to the Pooling and Servicing Agreement and
any proceeds thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements
(to the extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement
policies given as additional security for any related Mortgage Loans or Trust Subordinate Companion Loans (to the extent of the

earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent
such interest belongs to the related Mortgagor).


 


This Certificate does
not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing Agreement for
the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same
Class.

of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes whatsoever, and none of the
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any

     A-26-9


     


    

 


The Pooling and Servicing

of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement
or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no
such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
or the Trust Subordinate Companion Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required

Certificates, in any such case, without the consent of the Holders of all Certificates of such Class then-outstanding or such Companion
Holders, as applicable; or



 


		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or



 


		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations

Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.



 






     A-26-10


     


    

 


Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.


 


The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan), the Trust Subordinate Companion
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust
and early retirement of the then-outstanding Certificates, only on or after the first Distribution Date on which the aggregate
Stated Principal Balances of the Mortgage Loans, the Trust Subordinate Companion Loans and the portion of any REO Loans held by
the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation,
if such right is being exercised after December 2027 and the 237 East Fordham Road Mortgage Loan is still an asset of the Trust,
then such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust
Subordinate Companion Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans and Trust Subordinate
Companion Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans,
the Trust Subordinate Companion Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and
Servicing Agreement.


 


The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the

Trust
created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date
hereof.


 


Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates, the Mortgage Loans
or the Trust Subordinate Companion Loans.

	STATE
OF	)

              )          ss.:
	COUNTY OF	)


  


I,
[______], under penalties of perjury, declare that, to the best of my knowledge and belief, the following representations are
true, correct and complete, and being first sworn, depose and say that:


 


1.       I
am a [______] of [______] (the “Purchaser”), on behalf of which I have the authority to make this affidavit.


 


2.       The
Purchaser is acquiring Class R Certificates representing [__]% of the residual interest in each of the real estate mortgage investment
conduits (each, a “REMIC”) designated as the (i) “Lower-Tier REMIC”, (ii) “Upper-Tier
REMIC”, (iii) “Y&L Towers Trust Subordinate Companion Loan REMIC” and (iv) “Standard
Highline Trust Subordinate Companion Loan REMIC”, respectively, relating to the Certificates for which an election is
to be made under Section 860D of the Internal Revenue Code of 1986 (the “Code”).


 


3.       The
Purchaser is not a Disqualified Organization (as defined below), and that the Purchaser is not acquiring the Class R
Certificates for the account of, or as agent or nominee of, or with a view to the transfer of direct or indirect record or
beneficial ownership


 






    Exhibit D-1-1


     


    

 


thereof, to a Disqualified Organization. For the purposes hereof, a “Disqualified
Organization” is any of the following: (i) the United States, any State or political subdivision thereof, any
possession of the United States or any agency or instrumentality of any of the foregoing (other than an instrumentality which
is a corporation if all of its activities are subject to tax and, except for Freddie Mac, a majority of its board of
directors is not selected by such governmental unit), (ii) a foreign government, any international organization or any agency
or instrumentality of any of the foregoing, (iii) any organization which is exempt from the tax imposed by Chapter 1 of the
Code (including the tax imposed by Section 511 of the Code on unrelated business taxable income) on any excess inclusions (as
defined in Section 860E(c)(1) of the Code) with respect to the Class R Certificates (except certain farmers’
cooperatives described in Section 521 of the Code), (iv) rural electric and telephone cooperatives described in Section
1381(a)(2)(C) of the Code, (v) an “electing large partnership”, as defined in Section 775 of the Code and (vi)
any other Person so designated by the Trustee or the Certificate Administrator based upon an Opinion of Counsel as provided
to the Trustee or the Certificate Administrator (at no expense to the Trustee or the Certificate Administrator) that the
holding of an Ownership Interest in a Class R Certificate by such Person may cause any Trust REMIC to fail to qualify as
a REMIC at any time that the Certificates are outstanding or any Person having an Ownership Interest in any Class of
Certificates (other than such Person) to incur a liability for any federal tax imposed under the Code that would not
otherwise be imposed but for the Transfer of an Ownership Interest in a Class R Certificate to such Person. The terms
“United States,” “State” and “international organization” shall have the meanings set
forth in Section 7701 of the Code or successor provisions.


 


4.       The
Purchaser acknowledges that Section 860E(e) of the Code would impose a substantial tax on the transferor or, in certain circumstances,
on an agent for the transferee, with respect to any transfer of any interest in any Class R Certificates to a Disqualified Organization.


 


5.       The
Purchaser is a Permitted Transferee and, to the extent applicable, the Purchaser’s U.S. taxpayer identification number is
[__________].


 


6.       No
purpose of the acquisition of the Class R Certificates is to impede the assessment or collection of tax.


 


7.       The
Purchaser will not cause income from the Class R Certificate to be attributable to a foreign permanent establishment or fixed
base, within the meaning of an applicable income tax treaty, of the Purchaser or any other person.


 


8.       Check
the applicable paragraph: 


 


☐      The
present value of the anticipated tax liabilities associated with holding the Class R Certificate, as applicable, does not exceed
the sum of:


 


(i)      the
present value of any consideration given to the Purchaser to acquire such Class R Certificate; 


 


(ii)     the
present value of the expected future distributions on such Class R Certificate; and


 






    Exhibit D-1-2


     


    

 


(iii)    the
present value of the anticipated tax savings associated with holding such Class R Certificate as the related REMIC generates losses.


 





For
purposes of this calculation, (i) the Purchaser is assumed to pay tax at the highest rate currently specified in Section 11(b)
of the Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in
Section 11(b) of the Code if the Purchaser has been subject to the alternative minimum tax under Section 55 of the Code
in the preceding two years and will compute its taxable income in the current taxable year using the alternative minimum tax rate)
and (ii) present values are computed using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d)
of the Code for the month of the transfer and the compounding period used by the Purchaser.


 


☐      The
transfer of the Class R Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,


 


(i)      the
Purchaser is an “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as
to which income from the Class R Certificate will only be taxed in the United States;


 


(ii)     at
the time of the transfer, and at the close of the Purchaser’s two fiscal years preceding the year of the transfer, the Purchaser
had gross assets for financial reporting purposes (excluding any obligation of a person related to the Purchaser within the meaning
of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;


 


(iii)    the
Purchaser will transfer the Class R Certificate only to another “eligible corporation,” as defined in Treasury Regulations
Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of Sections 1.860E-1(c)(4)(i), (ii) and
(iii) and Treasury Regulations Section 1.860E-1(c)(5); and


 


(iv)    the
Purchaser determined the consideration paid to it to acquire the Class R Certificate based on reasonable market assumptions (including,
but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax
rates and other factors specific to the Purchaser) that it has determined in good faith.


 


☐      None
of the above.


 


9.       The
Purchaser historically has paid its debts as they have come due and intends to pay its debts as they come due in the future and
the Purchaser intends to pay taxes associated with holding the Class R Certificates as they become due.


 


10.     The
Purchaser understands that it may incur tax liabilities with respect to the Class R Certificate in excess of any cash flows generated
by such Certificate.


 


11.    The
Purchaser is aware that the Certificate Registrar will not register any transfer of a Class R Certificate by the Transferor unless
the Purchaser, or such Purchaser’s agent, delivers to the Certificate Registrar, among other things, an affidavit and agreement
in substantially the same form as this affidavit and agreement. The Purchaser expressly agrees that


 






    Exhibit D-1-3


     


    

 


it will not consummate any
such transfer if it knows or believes that any representation contained in such affidavit and agreement is false.


 


12.    The
Purchaser represents that it is not acquiring the Class R Certificate as a nominee, trustee or agent for any person that is not
a Permitted Transferee and that for so long as it retains its interest in the Class R Certificate, it will endeavor to remain
a Permitted Transferee.


 


13.    The
Purchaser consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificate will only be owned, directly or indirectly, by a Permitted Transferee.


 


14.    The
Purchaser has reviewed the provisions of Section 5.03 of the Pooling and Servicing Agreement, a description of which provisions
is set forth in the Class R Certificates; and the Purchaser expressly agrees to be bound by and to comply with such provisions.


 


15.    The
Purchaser consents to the designation of the Certificate Administrator as the agent of the “tax matters person” and
“partnership representative” of each Trust REMIC pursuant to Section 10.01 of the Pooling and Servicing Agreement.

Ladies
and Gentlemen:


 


This
letter is delivered to you in connection with the transfer by [______] (the “Transferor”) to [______] (the
“Transferee”) of Class R Certificates evidencing a [__]% Percentage Interest in such Class (the “Residual
Certificates”). The Certificates, including the Residual Certificates, were issued pursuant to the Pooling and Servicing
Agreement, dated as of November 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse
Commercial Mortgage Securities Corp., as Depositor, KeyBank National Association, as Master Servicer, Wells Fargo Bank, National
Association, as Certificate Administrator and as Trustee, CWCapital Asset Management LLC, as Special Servicer, and Park Bridge
Lender Services LLC, as Asset Representations Reviewer and as Operating Advisor. All capitalized terms used but not otherwise
defined herein shall have the respective meanings set forth in the Pooling and Servicing Agreement. The Transferor hereby certifies,
represents and warrants to you, as Certificate Registrar, that:


 





(1)       No
purpose of the Transferor relating to the transfer of the Residual Certificates by the Transferor to the Transferee is or will
be to impede the assessment or collection of any tax.


 


(2)       The
Transferor understands that the Transferee has delivered to you a Transferee Affidavit and Agreement in the form attached to the
Pooling and Servicing Agreement as Exhibit D-1. The Transferor does not know or believe that any representation contained
therein is false.


 


(3)       The
Transferor has at the time of this transfer conducted a reasonable investigation of the financial condition of the Transferee
as contemplated by Treasury regulation Section 1.860E-1(c)(4)(i) and, as a result of that investigation, the Transferor has determined
that the Transferee has historically paid its debts as they became due and has found no significant evidence to indicate that
the Transferee will not continue to pay its debts as they become due in the future. The Transferor understands that the transfer
of the Residual Certificates may not be


 






     Exhibit D-2-1


     

    

 


respected
for United States income tax purposes (and the Transferor may continue to be liable for United States income taxes associated
therewith) unless the Transferor has conducted such an investigation.

who is informed of the matters that are the subject of this Confidentiality Agreement to that effect.


 


You will treat the Confidential

demand, request for information or documents, deposition or similar process relating to any legal proceeding, investigation, hearing
or otherwise) to disclose any Confidential Information, you agree to provide the relevant Furnishing Entity with notice as soon
as practicable (except in the case of regulatory or other governmental inquiry, examination or investigation, and otherwise to

that confidential treatment will be accorded to the portion of the Confidential Information that is being disclosed, at the sole
expense of such Furnishing Entity; provided, however, that in no event shall the NRSRO be required to take a position
that such information should be entitled to receive such a protective order or reasonable assurance as to confidential treatment.
If a Furnishing Entity succeeds in obtaining a protective order or other remedy, you agree to comply with its terms with respect
to the disclosure of the Confidential Information, at the sole expense of such Furnishing Entity. If a protective order or other
remedy is not obtained or if the relevant Furnishing Entity waives compliance with the provisions of this Confidentiality Agreement
in writing, you agree to furnish only such information as you are legally required to disclose, at the sole expense of the relevant
Furnishing Entity.


 


Obligation to Return Evaluation Material.
Promptly upon written request by or on behalf of the relevant Furnishing Entity, all material or documents, including copies thereof,
that contain Evaluation Material will be destroyed or, in your sole discretion, returned to the relevant Furnishing Entity. Notwithstanding
the foregoing, (a) the NRSRO may retain one or more copies of any document or other material containing Evaluation Material
to the extent necessary for legal or regulatory compliance (or compliance with the NRSRO’s internal policies and procedures
designed to ensure legal or regulatory compliance) and (b) the NRSRO may retain any portion of the Evaluation Material that
may be found in backup tapes or other archive or electronic media or other documents prepared by the NRSRO and any Evaluation Material

Agreement. The NRSRO will be responsible for any breach of this Confidentiality Agreement by you, the NRSRO or any
NRSRO Representative.


 


You agree promptly
to advise each relevant Furnishing Entity in writing of any misappropriation or unauthorized disclosure or use by any person of
the Confidential Information which may come to your attention and to take all steps reasonably requested by such Furnishing Entity
to limit, stop or otherwise remedy such misappropriation, or unauthorized disclosure or use.

that the Furnishing Entities would not have an adequate remedy at law and would be irreparably harmed in the event that any of
the provisions of this Confidentiality Agreement were not performed in accordance with their specific terms or were otherwise breached.
It is accordingly agreed that each Furnishing Entity shall be entitled to specific performance and injunctive relief to prevent
breaches of this Confidentiality Agreement and to specifically enforce the terms and provisions hereof, in addition to any other
remedy to which a Furnishing Entity may be entitled at law or in equity. It is further understood and agreed that no failure to
or delay in exercising any right, power or privilege hereunder shall preclude any other or further exercise of any right, power
or privilege.


 






    Exhibit P-2-5


     


    

 


Term. Notwithstanding
the termination or cancellation of this Confidentiality Agreement and regardless of whether the NRSRO has provided a credit rating
on a Security, your obligations under this Confidentiality Agreement will survive indefinitely.

Confidentiality Agreement and any claim, controversy or dispute arising under the Confidentiality Agreement, the relationships
of the parties and/or the interpretation and enforcement of the rights and duties of the parties shall be governed by and construed
in accordance with the laws of the State of New York applicable to agreements made and to be performed within such State.


 


Amendments. This Confidentiality
Agreement may be modified or waived only by a separate writing by the NRSRO and each Furnishing Entity.


 


Entire Agreement.
This Confidentiality Agreement represents the entire agreement between you and the Furnishing Entities relating to the treatment
of Confidential Information heretofore or hereafter reviewed or inspected by you. This agreement supersedes all other understandings
and agreements between us relating to such matters; provided, however, that, if the terms of this Confidentiality
Agreement conflict with another agreement relating to the Confidential Information that specifically states that the terms of such
agreement shall supersede, modify or amend the terms of this Confidentiality Agreement, then to the extent the terms of this Confidentiality
Agreement conflict with such agreement, the terms of such agreement shall control notwithstanding acceptance by you of the terms
hereof by entry into this website.

                                         ____________________



 


Reference
is made to the Pooling and Servicing Agreement described above. Capitalized terms used but not defined herein have the meanings
assigned to such terms in the Pooling and Servicing Agreement.


 


As
Servicer under the Pooling and Servicing Agreement, we hereby:


 


(a)   Notify
you that the Mortgagor has consummated a defeasance of the Mortgage Loan pursuant to the terms of the [Mortgage Loan][Y&L
Towers Trust Subordinate Companion Loan][Standard Highline Trust Subordinate Companion Loan], of the type checked below:


 


____    a
full defeasance of the entire principal balance of the [Mortgage Loan][Y&L Towers Trust Subordinate Companion Loan][Standard
Highline Trust Subordinate Companion Loan]; or


 


____    a
partial defeasance of a portion of the principal balance of the [Mortgage Loan][Y&L Towers Trust Subordinate Companion Loan][Standard
Highline Trust Subordinate Companion Loan] that represents and, an allocated loan amount of $____________ or _______% of the entire
principal balance of the Mortgage Loan;


 


(b)   Certify
that each of the following is true, subject to those exceptions set forth with explanatory notes on Exhibit A hereto, which
exceptions the Master Servicer has determined, consistent with the Servicing Standards, will have no material adverse effect on
the [Mortgage Loan][Y&L Towers Trust Subordinate Companion Loan][Standard Highline Trust Subordinate Companion Loan] or the
defeasance transaction:


 





(i)           The
Mortgage Loan documents permit the defeasance, and the terms and conditions for defeasance specified therein were satisfied in
all material respects in completing the defeasance.


 


(ii)          The
defeasance was consummated on __________, 20__.


 


(iii)         The
defeasance collateral consists of securities that (i) constitute “government securities” as defined in Section 2(a)(16)
of the Investment Company Act of 1940 as amended (15 U.S.C. 80A1), (ii) are listed as “Qualified Investments


 






    Exhibit U-2


     


    

 


for
‘AAA’ Financings” under Paragraphs 1, 2 or 3 of “Cash Flow Approach” in Standard & Poor’s
Public Finance Criteria 2000, as amended to the date of the defeasance, (iii) if they include a principal obligation, the principal
due at maturity cannot vary or change, and (iv) are not subject to prepayment, call or early redemption.


 


(iv)         The
Master Servicer received an opinion of counsel (from counsel approved by the Servicer in accordance with the Servicing Standard)
that the defeasance will not result in an Adverse REMIC Event.


 


(v)          The
Master Servicer determined that the defeasance collateral will be owned by an entity (the “Defeasance Obligor”)
that is a Single-Purpose Entity (as defined in Standard & Poor’s Structured Finance Ratings Real Estate Finance Criteria,
as amended to the date of the defeasance (the “S&P Criteria”)) or is subject to restrictions in its organizational
documents substantially similar to those contained in the organization documents of the original Borrower with respect to bankruptcy
remoteness and single purpose as of the date of the defeasance, and after the defeasance owns no assets other than the defeasance
collateral and real property securing [Mortgage Loans included in the pool][the Y&L Towers Trust Subordinate Companion Loan][the
Standard Highline Trust Subordinate Companion Loan].


 


(vi)         The
defeasance documents require the crediting of the defeasance collateral to an Eligible Account (as defined in the S&P Criteria)
in the name of the Trustee on behalf of the Trust, which account is maintained as a securities account by a securities intermediary
and has been pledged to the Trustee on behalf of the Trust.


 


(vii)        The
agreements executed in connection with the defeasance (i) grant control of the pledged securities account to Trustee on behalf
of the Trust, (ii) require the securities intermediary to make the scheduled payments on the [Mortgage Loan][Y&L Towers Trust
Subordinate Companion Loan][Standard Highline Trust Subordinate Companion Loan] from the proceeds of the defeasance collateral
directly to the Master Servicer’s collection account in the amounts and on the dates specified in the Mortgage Loan documents
or, in a partial defeasance, the portion of such scheduled payments attributed to the allocated loan amount for the real property
defeased, increased by any defeasance premium specified in the Mortgage Loan documents (the “Scheduled Payments”),
(iii) permit reinvestment of proceeds of the defeasance collateral only in Permitted Investments (as defined in the Pooling and
Servicing Agreement or as defined in the documents evidencing the defeasance), (iv) permit release of surplus defeasance collateral
and earnings on reinvestment from the pledged securities account only after the [Mortgage Loan][Y&L Towers Trust Subordinate
Companion Loan][Standard Highline Trust Subordinate Companion Loan] has been paid in full, if any such release is permitted, (v)
prohibit transfers by the Defeasance Obligor of the defeasance collateral and subordinate liens against the defeasance collateral,
and (vi) provide for payment from sources other than the defeasance collateral or other assets of the Defeasance Obligor of all
fees and expenses of the securities intermediary for administering the


 






    Exhibit U-3


     


    

 


defeasance
and the securities account and all fees and expenses of maintaining the existence of the Defeasance Obligor.


 


(viii)       The
Master Servicer received written confirmation from a firm of independent certified public accountants, who were approved by the
Master Servicer in accordance with the Servicing Standard stating that (i) revenues from the defeasance collateral (without taking
into account any earnings on reinvestment of such revenues) will be sufficient to timely pay each of the Scheduled Payments after
the defeasance including the payment in full of the [Mortgage Loan][Y&L Towers Trust Subordinate Companion Loan][Standard
Highline Trust Subordinate Companion Loan] (or the allocated portion thereof in connection with a partial defeasance) on its Maturity
Date (or, in the case of an ARD Loan, on its Anticipated Repayment Date), (ii) the revenues received in any month from the defeasance
collateral will be applied to make Scheduled Payments within four (4) months after the date of receipt, and (iii) interest income
from the defeasance collateral to the Defeasance Obligor in any calendar or fiscal year will not exceed such Defeasance Obligor’s
interest expense for the [Mortgage Loan][Y&L Towers Trust Subordinate Companion Loan][Standard Highline Trust Subordinate
Companion Loan] (or the allocated portion thereof in a partial defeasance) for such year.


 


(ix)          The
Mortgage Loan is not among the ten (10) largest loans in the pool as of the date of the Current Report (as defined below). The
entire principal balance of the Mortgage Loan as of the date of defeasance was less than both $[______] and five percent of pool
balance, which is less than [__]% of the aggregate Certificate Balance of the Certificates as of the date of the most recent Distribution
Date Statement received by us (the “Current Report”).


 


(x)           The
Master Servicer has received opinions of counsel stating that the Trustee on behalf of the Trust possesses a valid, perfected
first priority security interest in the defeasance collateral and that the documents executed in connection with the defeasance
are enforceable in accordance with their respective terms.


 


(c)           Certify
that Exhibit B hereto is a list of the material agreements, instruments, organizational documents for the Defeasance Obligor,
and opinions of counsel and independent accountants executed and delivered in connection with the defeasance.


 


(d)           Certify
that the individual under whose hand the Master Servicer has caused this Notice and Certification to be executed did constitute
a Servicing Officer as of the date of the defeasance described above.


 


(e)           Agree
to provide copies of all items listed in Exhibit B to you upon request.

WITNESS WHEREOF, the Master Servicer has caused this Notice and Certification to be executed as of the date captioned above.

                                         of Mortgage Loans that Were Considered in Compiling this Report



 


		1.	The
                                         Special Servicer has notified the Operating Advisor that [●] Specially Serviced
                                         Loans were transferred to special servicing in the prior calendar year [INSERT YEAR].



 


		a.	[●]
                                         of those Specially Serviced Loans are still being analyzed by the Special Servicer as
                                         part of the development of an Asset Status Report.

                                         Status Reports were issued with respect to [●] of such Specially Serviced Loans.
                                         This report is based only on the Specially Serviced Loans in respect of which an Asset
                                         Status Report has been issued. The Asset Status Reports may not yet be fully implemented.



 


		2.	[●]
                                         Mortgage Loans were the subject of a Major Decision as to which the operating advisor

		II.	Executive
                                         Summary



 


Based
on the requirements and qualifications set forth in the PSA, as well as the items listed below, the Operating Advisor (in accordance
with the Operating Advisor’s analysis requirements outlined in the PSA) has undertaken a limited review of the Special Servicer’s
reported actions on the loans identified in this report. Based solely on such limited review and subject to the assumptions, limitations
and qualifications set forth herein, the Operating Advisor believes, in its sole discretion exercised in good faith, that the
Special Servicer [is/is not] operating in compliance with the Servicing Standard with respect to its performance of its duties
under the PSA during the prior calendar year on an “asset-level basis”. [The Operating Advisor believes, in its sole
discretion exercised in good faith, that the Special Servicer has failed to comply with the Servicing Standard as a result of
the following material deviations.]


 


		●	[LIST
                                         OF MATERIAL DEVIATION ITEMS]

report is an indicative report and does not reflect the final form of annual report to be used in any particular year. The Operating
Advisor will have the ability to modify or alter the organization and content of any particular report, subject to the compliance
with the terms of the PSA, including, without limitation, provisions relating to Privileged Information.

In
connection with the assessment set forth in this report, the Operating Advisor:


 


		1.	Reviewed
                                         the Asset Status Reports, the Special Servicer’s assessment of compliance report,
                                         attestation report by a third party regarding the Special Servicer’s compliance
                                         with its obligations and net present value calculations, Collateral Deficiency Amount
                                         calculations and Appraisal Reduction Amount calculations and [LIST OTHER REVIEWED INFORMATION]
                                         for the following [●] Specially Serviced Loans: [List related Mortgage Loans]



 


		2.	Consulted
                                         with the Special Servicer as provided under the PSA. The Operating Advisor’s analysis
                                         of the Asset Status Reports (including related net present value calculations, Collateral
                                         Deficiency Amount calculations and Appraisal Reduction Amount calculations) related to
                                         the Specially Serviced Loans should be considered a limited investigation and not be
                                         considered a full or limited audit. For instance, we did not re-engineer the quantitative
                                         aspects of their net present value calculator, visit any property, visit the Special
                                         Servicer, visit the Directing Certificateholder or interact with any borrower. In addition,
                                         our review of the net present value calculations, Collateral Deficiency Amount calculations

                                         of the Pooling and Servicing Agreement, the Operating Advisor did not participate in,
                                         or have access to, the Special Servicer’s and Directing Holder’s discussion(s)
                                         regarding any Specially Serviced Loan. The Operating Advisor does not have any obligation
                                         to speak with the Directing Holder or borrower directly. As such, the Operating Advisor

                                         with the Special Servicer, if any, in gathering the relevant information to generate
                                         this report. The services that we perform are not designed and cannot be relied upon

                                         has no responsibility or authority to alter the standards set forth therein or the actions
                                         of the Special Servicer.



 


		5.	Confidentiality
                                         and other contractual limitations limit the Operating Advisor’s ability to outline
                                         the details or substance of any communication held between it and the Special Servicer
                                         regarding any Specially Serviced Loans and certain information it reviewed in connection
                                         with its duties under the Pooling and Servicing Agreement. As a result, this report may
                                         not reflect all the relevant information that the Operating Advisor is given access to
                                         by the Special Servicer.



 


		6.	There
                                         are many tasks that the Special Servicer undertakes on an ongoing basis related to Specially
                                         Serviced Loans. These include, but are not limited to, assumptions, ownership changes,
                                         collateral substitutions, capital reserve changes, etc. The Operating Advisor does not
                                         participate in any discussions regarding such actions. As such, Operating Advisor has
                                         not assessed the Special Servicer’s operational compliance with respect to those
                                         types of actions.

                                         Operating Advisor is not empowered to speak with any investors directly. If the investors
                                         have questions regarding this report, they should address such questions to the Certificate
                                         Administrator through the Certificate Administrator’s website.



 


		8.	This
                                         report does not constitute recommendations to buy, sell or hold any security, nor does
                                         the Operating Advisor take into account market prices of securities or financial markets
                                         generally when performing its limited review of the Special Servicer as described above.

                                         not have a fiduciary relationship with any Certificateholder or any other party or individual.

Ladies
and Gentlemen:


 


Reference
is hereby made to that certain Pooling and Servicing Agreement dated as of November 1, 2017 (the “Pooling and Servicing
Agreement”), among the Credit Suisse Commercial Mortgage Securities Corp., as Depositor, KeyBank National Association,
as Master Servicer, CWCapital Asset Management LLC, as Special Servicer, Wells Fargo Bank, National Association, as Certificate
Administrator and as Trustee, and Park Bridge Lender Services LLC, as Asset Representations Reviewer and as Operating Advisor.
Defined terms used herein and not otherwise defined shall have the meanings set forth in the Pooling and Servicing Agreement.


 


KeyBank
National Association (“KeyBank”)/CWCapital Asset Management LLC (“CWCapital”) understands
that [____] (the “Company”) is requesting certain confidential or non-public information relating to the Mortgage
Loans and the Trust Subordinate Companion Loans to which the Company has continuing rights as a Certificateholder. The Company
is requesting such information for the purpose of analyzing asset performance and evaluating any continuing rights the Company
may have under the Trust (the “Permitted Purpose”). The


 






    Exhibit X-1


     


    

 




[_____]
[__], 20[__] 

Page 2


 



Company
agrees that the Permitted Purpose shall not include the use or disclosure of the Confidential Information (as defined below) in
any manner that violates any applicable law, the Pooling and Servicing Agreement or the related mortgage loan documents.


 


KeyBank/CWCapital
will provide the Company with certain confidential, non-public servicing information (the “Confidential Information”)
pertaining to the Mortgage Loans and the related Mortgaged Properties and borrowers. The Company acknowledges that the Confidential
Information (a) includes or may be based upon information provided to KeyBank/CWCapital by third parties, (b) may not have been
verified by KeyBank/CWCapital, and (c) may be incomplete or contain inaccuracies. The Company agrees that KeyBank/CWCapital, the
[“Master Servicer”/”Special Servicer”] (as defined in the Pooling and Servicing Agreement)
and their respective Representatives (as defined below) shall not have any liability to the Company or its Representatives resulting
from (x) any inaccuracies or omissions in the Confidential Information, (y) any use of the Confidential Information, or (z) KeyBank/CWCapital’s
failure or inability to provide the Confidential Information to the Company for any reason. Notwithstanding the foregoing, the
following will not constitute “Confidential Information” for purposes of this letter agreement: (a) information
that was already in Company’s possession prior to its receipt from KeyBank/CWCapital; (b) information that is obtained by
Company from a third person who, insofar as is known to Company, is not prohibited from transmitting the information to Company
by a contractual, legal or fiduciary obligation to KeyBank/CWCapital; (c) information that is or becomes publicly available through
no fault of Company; and (d) information that is independently developed by Company. The term “Representatives” with
respect to any entity shall mean the officers, directors, general partners, employees, agents, affiliates, auditors and legal
counsel (which may be internal counsel) of that entity.


 


The
Company may have access to the Confidential Information through (at KeyBank/CWCapital’s election): (i) responses to reasonable
written inquiries received from the Company, (ii) conference calls conducted on a reasonably scheduled basis with KeyBank/CWCapital’s
surveillance group, or (iii) direct on-line access (read-only capacity) to the information available on the applicable [____]
system or any successor or replacement system (“System”). KeyBank/CWCapital may cease or defer providing the
Company with Confidential Information in the event that (a) the Company or its Representatives violate any provision hereof, or
(b) KeyBank/CWCapital determines (in its sole discretion) that such termination is necessary for any reason, including its determination
that such action is required pursuant to the terms of the Pooling and Servicing Agreement, the related Mortgage Loan documents,
or any applicable law. KeyBank/CWCapital shall cease to provide the Company with Confidential Information if KeyBank/CWCapital
has actual knowledge that the Company or its Representatives are affiliates of any borrower under the Mortgage Loan documents
and KeyBank/CWCapital determines that the provision, notice or access to such Confidential Information would violate the accepted
servicing practices or servicing standards as defined in the Pooling and Servicing Agreement. The Company’s obligations
and the restrictions applicable to the protection of the Confidential Information hereunder shall survive the termination of the
Company’s access to the Confidential Information. KeyBank/CWCapital’s remedies hereunder, at law or at equity, are
cumulative and may be combined.


 


The
Company agrees that it will not, and it shall not permit its Representatives, to disclose the Confidential Information in any
manner whatsoever to any other person or entity, other than its


 






    Exhibit X-2

Representatives
(but only to the extent necessary to accomplish the Permitted Purpose) who have a need to know the information, or as otherwise
required by applicable law, court order or any governmental agency or regulator. The Company acknowledges (i) its obligations
under the U.S. federal securities laws, and (ii) that any disclosure of the Confidential Information by it or its Representatives
for any purpose other than a Permitted Purpose, in addition to being a breach of this letter agreement, may constitute a violation
of federal and state securities laws. The Company will take reasonable measures to ensure that each Representative is advised
of this letter agreement and agrees to keep the Confidential Information confidential. The Company shall be liable for any breach
of this letter agreement by its Representatives. Notwithstanding the foregoing, the Company may subsequently provide all or any
part of such Confidential Information to any other person or entity that holds or is contemplating the purchase of any Certificate
or interest therein, but only if such person or entity confirms such ownership interest or prospective ownership interest and
provided that, prior to the delivery of such Confidential Information, such persons shall have executed and delivered to
the Company an agreement that is substantially similar in form and substance to this Agreement.


 


This
letter agreement shall be governed by and construed in accordance with the laws of the State of New York without the application
of conflict of laws principles. Anything herein to the contrary notwithstanding, KeyBank/CWCapital intends at all times to comply
with the terms and provisions of the Pooling and Servicing Agreement and nothing in this letter agreement should be construed
to limit or qualify any of KeyBank/CWCapital’s rights or obligations under the Pooling and Servicing Agreement. This letter
agreement may be executed in counterparts and by facsimile/Portable Document Format (PDF); each such counterpart shall be deemed
to be an original instrument, and all such counterparts together shall constitute one agreement.


 


This
agreement shall terminate with respect to the information received by the Company one year after the Company receives such information
or ceases to be a Certificateholder. Company agrees that this letter agreement supersedes and replaces and survives any click-through
agreement regarding confidentiality of Confidential Information agreed to in connection with accessing the System whether agreed
to in accessing the System before or after signing this letter agreement.

and the Certificate Administrator (or the Master Servicer, to the extent specified in Section 11.04 of the Pooling and Servicing
Agreement) any information described in the corresponding Form 10-D Item described in the “Item on Form 10-D” column
to the extent such party has knowledge (and in the case of net operating income information, financial statements, annual operating
statements, budgets and/or rent rolls required to be provided in connection with Item 6 below, possession) of such information
(other than information as to itself). Each of the Certificate Administrator, the Trustee, the Master Servicer and the Special
Servicer (in its capacity as such) shall be entitled to rely on the accuracy of the Prospectus (other than information with respect

Administrator, the Trustee, the Master Servicer and the Special Servicer (in its capacity as such) shall be entitled to assume

ASSET
REVIEW PROCEDURES


 


Subject
to the Pooling and Servicing Agreement, this Exhibit sets forth Asset Representations Reviewer’s review procedures for each
Delinquent Loan based on the information provided for an Asset Review. Capitalized terms used herein and not defined herein shall
have the meanings ascribed to them in the Pooling and Servicing Agreement. In the event of any conflict between this Exhibit QQ
and the terms of the Pooling and Servicing Agreement, the Pooling and Servicing Agreement shall control and govern the Asset Representation
Reviewer’s responsibilities and duties with respect to Asset Reviews.


 


Call
for Review and Collection and Inventory of Review Materials 


 


Step
1 Asset Representations Reviewer (“ARR”) receives the following items before beginning its review
from the parties specified in Section [ ] of the Pooling and Servicing Agreement:


 


		■	Notice
                                         of Asset Review Trigger (with attachments)



 


		■	Asset
                                         Review Vote Election



 


		■	Notice
                                         of Affirmative Asset Review Vote



 


		■	List
                                         of all Delinquent Loans subject to the Asset Review



 


		■	Review
                                         Materials for each Delinquent Loan via Secure Data Room access, including the Diligence
                                         File



 


		■	Any
                                         Unsolicited Information (if applicable)



 


Step
2 For each Delinquent Loan, ARR inventories all Review Materials to which ARR is provided access in the Secure
Data Room to determine what, if any, Review Materials for such Delinquent Loan are missing, using the list of documents in Section
[ ] through Section [ ] of this Agreement, any comparable lists included in the related Mortgage Loan Purchase Agreement,
and any closing checklist from the origination of such Delinquent Loan, to guide its review and determination


 


Step
3 If ARR determines that the information made available to it in the Secure Data Room with respect to any Delinquent
Loan is missing any documents required to complete an Asset Review of such Delinquent Loan, ARR shall prepare a list of such missing
documents and notify Master Servicer (with respect to Non-Specially Serviced Loans) and Special Servicer (with respect to Specially
Serviced Loans) of such missing documents. If the Master Servicer or Special Servicer, as applicable, does not provide such document
as provided in the Pooling and Servicing Agreement, the ARR shall notify the related Mortgage Loan Seller of such missing information

Analysis
and Testing of Representations and Warranties


 


Step
4 For each Delinquent Loan for which ARR has received all Review Materials required to complete an Asset Review
of such Delinquent Loan, ARR tests such Delinquent Loan for compliance with each representation and warranty made by the related
Mortgage Loan Seller with respect to such Delinquent Loan as follows:


 


		■	ARR
                                         reviews each representation and warranty and each item included in the Review Materials
                                         applicable or related to such representation or warranty to determine whether there is
                                         any evidence that such representation or warranty was not true when made by the related
                                         Mortgage Loan Seller



 


		■	For
