This
Pooling and Servicing Agreement is dated and effective as of October 1, 2017, among UBS Commercial Mortgage Securitization Corp.,
as Depositor, Wells Fargo Bank, National Association, as Master Servicer, Rialto Capital Advisors, LLC as Special Servicer, AEGON
USA Realty Advisors, LLC, as Fairmount at Brewerytown Special Servicer, Wells Fargo Bank, National Association, as Certificate
Administrator, Wilmington Trust, National Association, as Trustee, and Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer.


 


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. 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 two (2) separate real estate mortgage investment conduits (the “Upper-Tier REMIC”
and the “Lower-Tier REMIC”, and each a “Trust REMIC” as described herein).


 


In
addition, the parties intend that the portion of the Trust Fund consisting of the Class Z Specific Grantor Trust Assets shall
be treated as a grantor trust under subpart E, part I of subchapter J of the Code for federal income tax purposes (the “Grantor
Trust”). Solely for tax purposes, the Class Z Certificates shall represent undivided beneficial interests in the
Class Z Specific Grantor Trust Assets. 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 either Trust REMIC.


 


The
Depositor intends to sell the Certificates to the Underwriters and the Initial Purchasers.


 


LOWER-TIER
REMIC


 


The
Lower-Tier REMIC will hold the Mortgage Loans (exclusive of Excess Interest) and will issue the Class LA1, Class LA2,
Class LASB, Class LA3, Class LA4, Class LAS, Class LB, Class LC, Class LD, Class LE, Class
LF, Class LG and Class LNR (the “Lower-Tier Regular Interests”), which will evidence the “regular interests”
in the Lower-Tier REMIC created hereunder. The Lower-Tier REMIC will also issue the uncertificated Class LR Interest, which
is the sole Class of “residual interests” in the Lower-Tier REMIC for purposes of the REMIC Provisions and is represented
by the Class R Certificates.


 


The
following table sets forth the Original Lower-Tier Principal Amounts and per annum rates of interest for the Lower-Tier
Regular Interests and the Class LR Interest:

required to be included therein unless they are actually
received by the Custodian, (b) if there exists with respect to any Crossed Mortgage Loan Group only one original or certified
copy of any document referred to in the definition of “Mortgage File” covering all of the Mortgage Loans in such Crossed

“Nonrecoverable
Advance”: Any Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance. For the avoidance of doubt, Workout-Delayed
Reimbursement Amounts shall constitute Nonrecoverable Advances only when the Person making such determination in accordance with
the procedures specified herein, and taking into account factors such as all other outstanding Advances, either (a) has determined
that such Workout-Delayed Reimbursement Amounts, would not ultimately be recoverable from Late Collections, Default Interest,
Insurance and Condemnation Proceeds, Liquidation Proceeds or any other recovery on or in respect of such Mortgage Loan or the
related REO Property (without giving effect to potential recoveries on deficiency judgments or recoveries from guarantors), or
(b) has determined that such Workout-Delayed Reimbursement Amount, along with any other Workout-Delayed Reimbursement Amounts
(that have not been reimbursed to the party that made such Advance) or unreimbursed Nonrecoverable Advances, would not be ultimately
recoverable from the principal portion of future general collections on the Mortgage Loans and REO Properties.


 


“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) or REO Loan (other than any portion of an REO Loan related to a Companion Loan) which, in the
reasonable judgment of the Master Servicer, the Special Servicer or the Trustee, as the case may be, will 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 or REO Loan; provided, however, that the Special Servicer may, at its option,
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 (other than by the Special Servicer) shall not be binding upon (but may be conclusively
relied upon by) the Master Servicer and the Trustee, and any such determination by the Special Servicer shall be conclusive and
binding upon the Master Servicer and the Trustee (but this statement shall not be construed to entitle the Special Servicer to
reverse the determination of the Master Servicer or the Trustee or to prohibit the Master Servicer or the Trustee from making
a determination that a P&I Advance would be a Nonrecoverable Advance), provided, however, that the Special Servicer
shall have no such obligation to make an affirmative determination that any P&I Advance is or would be recoverable and in
the absence of a


 



     -76-


     


    

 


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, Non-Serviced Trustee 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 nonrecoverable, 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; provided,
however, the Master Servicer and the Trustee may rely on the non-recoverability determination of the Other Master Servicer
or Other Trustee under the related Non-Serviced Pooling Agreement. 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, related Non-Serviced Special 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 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 changes
with respect to such Mortgaged Properties, (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 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, 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 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 recovery, in light of the fact that proceeds on the related Mortgage Loan are a source of recovery 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


 



     -77-


     


    

 


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 the case may be, that a Nonrecoverable P&I Advance has been made 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 other
than an Excluded Loan as to such party) (and, in the case of a Serviced Mortgage Loan, any Other Servicer), 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, any Other
Servicer). 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, 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 Mortgage Loan or the related Mortgaged Property). The Trustee shall be
entitled to conclusively rely on the Master Servicer’s or the 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. 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), Serviced Whole Loan or REO Property which the Trustee determines in its reasonable business
judgment, or the Master Servicer or Special Servicer determines in accordance with the Servicing Standard, as the case may be,
will 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, Serviced 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 changes with respect


 



     -78-


     


    

 


to such Mortgaged Properties, (b) 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) 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) 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 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. 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 Servicing Advance shall be conclusive and binding on the Certificateholders.
The determination by the Master Servicer, the Special Servicer or the Trustee, as the case may be, that a Nonrecoverable Servicing
Advance has been made 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
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 other than an Excluded Loan as to such party) (and, in the case of a Serviced
Mortgage Loan, any Other Servicer), 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, any Other Servicer); provided, however, that the Special Servicer
may, at its option, 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 Certificate Administrator, the Trustee, the Operating Advisor and the 17g-5 Information
Provider notice of such determination. Any such determination (other than by the Special Servicer) shall not be binding upon (but
may be conclusively relied upon by) the Master Servicer and the Trustee, and any such determination by the Special Servicer shall
be binding upon the Master Servicer and the Trustee (but this


 



     -79-


     


    

 


statement shall not be construed to entitle the Special Servicer
to reverse the determination of the Master Servicer or the Trustee or to prohibit the Master Servicer or the Trustee from making
a determination that a Servicing Advance would be a Nonrecoverable Advance), provided, however, that the Special
Servicer shall have no 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, 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
with respect to the related Mortgage Loan, Serviced Companion Loan or related Mortgaged Property). The Special Servicer shall
promptly furnish 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 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 or property protection 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 related Non-Serviced PSA.

cash flows, including property cash flow, the “discount rate” set forth in the most recent Appraisal (or update of
such Appraisal) of the related Mortgaged Property.


 


(v)       Any

be construed to mean, for any Serviced Mortgage Loan, an expense that shall be applied in accordance with the related Intercreditor
Agreement or, if no application is specified in the related Intercreditor Agreement, then, to the extent such Intercreditor Agreement
refers to this Agreement for the application of trust fund expenses or such Intercreditor Agreement does not prohibit the following

of Sections 10, 13 and 15 thereof in connection with any exercise of rights under the assigned Sections, and the Depositor

(b)       In
connection with the Depositor’s assignment pursuant to subsection (a) above, the Depositor shall direct, and

Date, the Mortgage Note relating to each Mortgage Loan so assigned, endorsed to the Trustee or in blank as specified in clause
(i) of the definition of “Mortgage File” (or, alternatively, if the original executed Mortgage Note has been lost,
a lost note affidavit and indemnity with a copy of such Mortgage Note as specified in clause (i) of the definition of “Mortgage
File”) and (B) on or before the date that is 45 days following the Closing Date (or such later date as may be provided under
Section 2.01(b) and (c) hereof with regard to any item), the remainder of the Mortgage File for each Mortgage Loan
and, except in the case of a Mortgage Loan that is a Non-Serviced Whole Loan as of the Closing Date (which delivery shall be subject
to clause (e) of the first proviso to the definition of “Mortgage File”), any other items required to
be delivered or deposited by the Mortgage Loan Seller pursuant to this Agreement (other than amounts from reserve accounts and
originals of letters of credit, which shall be transferred to the Master Servicer) for each Mortgage Loan. If the applicable Mortgage
Loan Seller cannot deliver, or cause to be delivered, as to any Mortgage Loan, the original Mortgage Note, the delivery requirements
of the applicable Mortgage Loan Purchase Agreement and this Section 2.01(b) shall be deemed to have been satisfied upon
such Mortgage Loan Seller’s delivery of a copy or duplicate original of such Mortgage Note, together with an affidavit certifying
that the original thereof has been lost or destroyed and indemnifying the Trustee and the Trust. If the applicable Mortgage Loan
Seller cannot deliver, or cause to be delivered, as to any Mortgage Loan, any of the documents and/or instruments referred to
in clauses (ii), (iv), (vii) and (ix) of the definition of “Mortgage File” (or, if
applicable, a copy thereof) with evidence of filing or recording thereon (if intended to be recorded or filed), solely because
of a delay caused by the public filing or recording office where such document or instrument has been delivered, or will be delivered
within ten (10) Business Days of the Closing Date, for filing or recordation, the delivery requirements of the applicable Mortgage
Loan Purchase Agreement and this Section 2.01(b) shall be deemed to have been satisfied on a provisional basis as of the
Closing Date as to such non-delivered document or instrument, and such non-delivered document or instrument shall be deemed to
have been included in the Mortgage File, if a duplicate original or a


 






     -133-


     


    

 


photocopy
of such non-delivered document or instrument (certified by the applicable public filing or recording office, the applicable title
insurance company or the applicable Mortgage Loan Seller to be a true and complete copy of the original thereof submitted or to
be submitted for filing or recording) is delivered to the Custodian on or before the date set forth herein, and either the original
of such non-delivered document or instrument, or a photocopy thereof (certified by the appropriate county recorder’s office
or the applicable title insurance company, in the case of the documents and/or instruments referred to in clause (ii)
of the definition of “Mortgage File”, to be a true and complete copy of the original thereof submitted for recording),
with evidence of filing or recording thereon, is delivered to the Custodian within one hundred-eighty (180) days of the Closing
Date (or within such longer period, not to exceed eighteen (18) months, after the Closing Date as the Custodian shall consent
to, which consent shall not be unreasonably withheld, as long as the applicable Mortgage Loan Seller is, as certified in writing
to the Trustee and the Custodian no less often than every ninety (90) days following such 180–day period after the Closing
Date, attempting in good faith to obtain from the appropriate public filing office or county recorder’s office such original
or photocopy). If the applicable Mortgage Loan Seller is required to, but cannot, deliver, or cause to be delivered, as to any
Mortgage Loan, any of the documents and/or instruments referred to in clauses (ii), (iv), (vii), and
(ix) (or, if applicable, a copy thereof) of the definition of “Mortgage File,” with evidence of filing or recording
thereon (if intended to be recorded or filed), for any other reason, including, without limitation, that such non-delivered document
or instrument has been lost or destroyed, the delivery requirements of the applicable Mortgage Loan Purchase Agreement and this
Section 2.01(b) shall be deemed to have been satisfied as to such non-delivered document or instrument, and such non-delivered
document or instrument shall be deemed to have been included in the Mortgage File, if a photocopy of such non-delivered document
or instrument (with evidence of filing or recording thereon and certified in the case of the documents and/or instruments referred
to in clause (ii) of the definition of “Mortgage File” by the appropriate county recorder’s office
or the applicable title insurance company to be a true and complete copy of the original thereof submitted for recording) is delivered
to the Custodian on or before the date set forth herein. Neither the Trustee nor any Custodian shall in any way be liable for
any failure by any Mortgage Loan Seller or the Depositor to comply with the delivery requirements of the related Mortgage Loan
Purchase Agreement and this Section 2.01(b). If, on the Closing Date as to any Mortgage Loan, subject to the next sentence,
the applicable Mortgage Loan Seller is required to, but cannot, deliver (in complete and recordable form or form suitable for
filing or recording, if applicable) any one of the assignments in favor of the Trustee referred to in clause (iii),
clause (v), or clause (x) of the definition of “Mortgage File” solely because of the unavailability
of filing or recording information as to any existing document or instrument, 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 with respect to such Mortgage Loan on the Closing Date an omnibus assignment of such Mortgage Loan substantially
in the form of Exhibit H; provided that all required original assignments with respect to such Mortgage Loan
(in fully complete and recordable form or form suitable for filing or recording, if applicable) are delivered to the Custodian
within one hundred-eighty (180) days after the Closing Date (or within such longer period, not to exceed eighteen (18) months,
which the Custodian shall consent to so long as the applicable Mortgage Loan Seller is, as certified in writing to the Trustee
and the Custodian no less often than every ninety (90) days following such 180–day period after the Closing Date, attempting
in good faith


 






     -134-


     


    

 


to obtain from the appropriate public filing office or county recorder’s office the applicable filing or recording
information as to the related document or instrument); and provided, further, that in the case of a Non-Serviced
Mortgage Loan, the delivery of any such assignments shall be subject to clause (e) of the first proviso to the definition
of “Mortgage File” herein. As to any Mortgage Loan, the related Mortgage Loan Seller or its agent is responsible for
recording or filing, as applicable, any one of the assignments in favor of the Trustee referred to in clause (iii),
clause (v), or clause (x) of the definition of “Mortgage File”, and 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 on the Closing Date a copy
of such assignment in the form sent for recording or filing or (except for recording or filing information not yet available)
to be sent for recording or filing; provided that an original or copy of such assignment (with evidence of recording or
filing, as applicable, indicated thereon) shall be delivered to the Custodian as contemplated by Section 2.01(c) of this
Agreement. Notwithstanding anything herein to the contrary, with respect to the delivery of a letter of credit in the manner described
in clause (A) of clause (xii) of the definition of “Mortgage File”, the applicable Mortgage
Loan Seller shall be deemed to have satisfied the delivery requirements of the related Mortgage Loan Purchase Agreement and this
Section 2.01(b) by delivering to the Custodian within ten (10) Business Days following the Closing Date with respect
to any such letter(s) of credit a copy of such letter of credit, the transfer documentation and such transmittal communication
to the issuing bank indicating that such document has been delivered to the issuing bank for reissuance. If a letter of credit
is not in a form that would allow 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 documents, the applicable Mortgage Loan Seller shall deliver
copies of the appropriate transfer or assignment documents to the Custodian promptly following receipt of written notification
thereof. If not otherwise paid by the related Mortgagor, the applicable Mortgage Loan Seller shall pay any transfer fee required
in order to transfer the beneficiary’s interest from such Mortgage Loan Seller to the Master Servicer on behalf of the Trust
as required hereunder and shall cooperate with the reasonable requests of the Master Servicer in connection with effectuating
a draw under any such letter of credit prior to the date such letter of credit is reissued to the Master Servicer on behalf of
the Trust. Regardless of the manner of delivery, the related Mortgage Loan Seller is required pursuant to the related Mortgage
Loan Purchase Agreement to indemnify the Trust for any liabilities, charges, costs, fees or other expenses accruing from the failure
of such Mortgage Loan Seller to assign all rights in and to the letter of credit hereunder including the right and power to draw
on the letter of credit.


 


(c)       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 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 applicable Mortgage Loan Seller 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 Section 2.01(c) and except in the case of a Non-Serviced
Mortgage


 






     -135-


     


    

 


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 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 (including, in the case of such Mortgage

third-party management agreements, asset summary and financial information on the borrower/sponsor and any guarantor, but in any
case 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, together with copies of all documents in each Mortgage File (to the extent not already
delivered or made available to the Master Servicer), 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 as Holder of the Lower-Tier Regular Interests) 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.

respect to the Mortgage Loans (other than any Non-Serviced Mortgage Loans) secured by the Mortgaged Properties identified on the
Mortgage Loan Schedule as Embassy Suites – Brea, Hilton Garden Inn Irvine/Orange County Airport, DoubleTree Orlando, Courtyard

Suites Chambersburg, and Holiday Inn Express & Suites Duncan, which are each subject to a franchise agreement with a related
comfort letter in favor of the respective Mortgage Loan Seller that requires notice to or request of the related franchisor to
transfer or assign any related comfort letter to the Trustee for the benefit of the Certificateholders or otherwise have a new
comfort letter (or any such new document or acknowledgement as may be contemplated under the existing comfort letter) issued in
the name of the Trustee for the benefit of the Certificateholders, the related Mortgage Loan Seller or its designee shall 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 forty-five
(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

deliver or cause to be delivered the Diligence Files for each of its Mortgage 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

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 applicable Mortgage Loan Seller (the “Diligence File Certification”).

of “Mortgage Loan Schedule” is correct. With respect to each Mortgage Loan listed on the Custodial Exception Report,
the Custodian shall specifically identify such Mortgage 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 Certificateholder and the
applicable Mortgage Loan Seller (as to each Mortgage 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 specifically identified in any exception report
annexed to such writing) that, (i) subject to the first proviso of the definition of “Mortgage File” herein and
Section 2.01, 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 be executed and relate to such Mortgage Loan, if applicable, 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 (viii) and (ix) in the definition of “Mortgage Loan Schedule”
is correct.


 


(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 pursuant to the related Mortgage Loan Purchase Agreement,
the Directing Certificateholder, in its sole judgment, may (other than with respect to any Excluded Loan with respect to 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


 






     -140-


     


    

 


Mortgage
Loan Seller in lieu of repurchasing or substituting for the related Mortgage 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 (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 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 the 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 (2) 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, defending any claim asserted by any Mortgagor or third party with respect to the related Mortgage Loan, establishing the
validity or priority of any lien on collateral securing the related Mortgage 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 in accordance with,
and to the extent required by, the terms and conditions of Section 2.03(b) and Section 5 of the related Mortgage Loan
Purchase Agreement; provided, however, that such Mortgage Loan Seller shall not be required to repurchase the Mortgage
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 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 (xviii) 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 delivered to


 






     -141-


     


    

 


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 (1) state level UCC Financing Statement filing for each Mortgaged Property
(or with respect to any Mortgage Loan that has two (2) 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 (2) 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 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 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 Certificateholder, 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, 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 a Repurchase Request or any other request or demand from any Person
for a Mortgage Loan Seller to repurchase or replace a Mortgage Loan because of an alleged Defect or Breach (together with a Repurchase
Request, a “15Ga-1 Repurchase Request”) (the Master Servicer or the Special Servicer, as applicable, to the
extent it receives such 15Ga-1 Repurchase Request, the


 






     -142-


     


    

 


“Repurchase
Request Recipient” with respect to such 15Ga-1 Repurchase Request); or (ii) receives any withdrawal of a 15Ga-1 Repurchase
Request by the Person making such 15Ga-1 Repurchase Request or any rejection of a 15Ga-1 Repurchase Request (or such 15Ga-1 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 15Ga-1 Repurchase Request or withdrawal or rejection of a 15Ga-1 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, (ii) the date the 15Ga-1 Repurchase Request
is received by the Repurchase Request Recipient or the date any withdrawal of the 15Ga-1 Repurchase Request is received by the
Repurchase Request Recipient, as applicable, (iii) if known, the basis for the 15Ga-1 Repurchase Request (as asserted in
the 15Ga-1 Repurchase Request), (iv) the identity of the Person making such 15Ga-1 Repurchase Request, and (v) a statement
from the Repurchase Request Recipient as to whether it currently plans to pursue such 15Ga-1 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 15Ga-1 Repurchase Request that is the subject of a
15Ga-1 Notice.


 


In
the event that the Depositor, the Trustee, the Special Servicer, the Certificate Administrator, the Operating Advisor, the Asset
Representations Reviewer or the Custodian receives a 15Ga-1 Repurchase Request, such party shall promptly forward or otherwise
provide written notice of such 15Ga-1 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 ‘15Ga-1 Repurchase Request’ under Section 2.02 of the Pooling and
Servicing Agreement relating to the UBS Commercial Mortgage Trust 2017-C4, Commercial Mortgage Pass-Through Certificates, Series
2017-C4 requiring action by you as the ‘Repurchase Request Recipient’ thereunder.” Upon receipt of such 15Ga-1
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 15Ga-1 Repurchase Request, and such party shall comply with the procedures set forth in this
Section 2.02(g) with respect to such 15Ga-1 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.


 






     -143-


     


    

 


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 15Ga-1 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 Certificate Registrar, 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 is repurchased or replaced pursuant to Section 2.03 of this Agreement, the Special Servicer
shall promptly notify the Depositor of such repurchase or replacement.


 


(h)       The
parties hereto acknowledge the obligation of each Mortgage Loan Seller pursuant to Section 2(d) of the related Mortgage Loan Purchase
Agreement to deliver at its expense, on or prior to the Closing Date, to the Special Servicer five (5) originals of limited powers
of attorney substantially in the form attached as Exhibit TT hereto in favor of the Special Servicer to empower the Special
Servicer to sign and/or deliver to a third party for submission, at the expense of the related Mortgage Loan Seller, any mortgage
loan documents required to be recorded as described in Section 2.01 of this Agreement and any intervening assignments with
evidence of recording thereon that are required to be included in the Mortgage Files (so long as original counterparts have previously
been delivered to the Trustee (or the Custodian on its behalf)); provided that if the Mortgage Loan Seller fails to promptly
pay the Special Servicer the expenses associated with recording documents as provided in this sentence, then such expenses shall
be payable out of the Trust (it being understood for the avoidance of doubt that the applicable Mortgage Loan Seller will nonetheless
remain responsible for reimbursing the Trust for such expenses). The Special Servicer shall not be liable for any failure of such
third party in connection with the foregoing, so long as the third party was chosen in accordance with the Servicing Standard.
Each Mortgage Loan Seller has agreed to reasonably cooperate with the Special Servicer in connection with any additional powers
of attorney or revisions thereto that are requested by the Special Servicer for purposes of such recordation. The parties hereto
agree that no such power of attorney shall be used with respect to any Mortgage Loan by or under authorization by any party hereto
except to the extent that the absence of a document described in the third preceding sentence with respect to such Mortgage Loan
remains unremedied as of the date on which such Mortgage Loan becomes a Specially Serviced Loan or at the time required for enforcement
by the Trust. The Special Servicer shall submit such documents for recording, at the related Mortgage Loan Seller’s expense,
after the date set forth above, provided, the Special Servicer shall not submit such assignments for recording if the related
Mortgage Loan Seller produces evidence that it or a third-party on its behalf has sent any such assignment for recording and certifies
that such Mortgage Loan Seller is awaiting its return from the applicable recording office.


 





 


Section
2.03       Representations, Warranties and Covenants of the Depositor; Mortgage Loan Sellers’ Repurchase or Substitution
of Mortgage Loans for Defects in Mortgage Files and Breaches of Representations and Warranties.  (a)  The
Depositor hereby represents and warrants that:


 






     -144-


     


    

 


(i)       The
Depositor is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware, and
the Depositor has taken all necessary corporate action to authorize the execution, delivery and performance of this Agreement
by it, and has the power and authority to execute, deliver and perform this Agreement and all the transactions contemplated hereby,
including, but not limited to, the power and authority to sell, assign and transfer the Mortgage Loans in accordance with this
Agreement;


 


(ii)       Assuming
the due authorization, execution and delivery of this Agreement by each other party hereto, this Agreement and all of the obligations
of the Depositor hereunder are the legal, valid and binding obligations of the Depositor, enforceable against the Depositor in
accordance with the terms of this Agreement, except as such enforcement may be limited by bankruptcy, insolvency, reorganization
or other similar laws affecting the enforcement of creditors’ rights generally, and by general principles of equity (regardless
of whether such enforceability is considered in a proceeding in equity or at law);


 


(iii)      The
execution and delivery of this Agreement and the performance of its obligations hereunder by the Depositor will not conflict with
any provisions of any law or regulations to which the Depositor is subject, or conflict with, result in a breach of or constitute
a default under any of the terms, conditions or provisions of the certificate of incorporation or the by-laws of the Depositor
or any indenture, agreement or instrument to which the Depositor is a party or by which it is bound, or any order or decree applicable
to the Depositor, or result in the creation or imposition of any lien on any of the Depositor’s assets or property, which
would materially and adversely affect the ability of the Depositor to carry out the transactions contemplated by this Agreement;
the Depositor has obtained any consent, approval, authorization or order of any court or governmental agency or body required
for the execution, delivery and performance by the Depositor of this Agreement;


 


(iv)     There
is no action, suit or proceeding pending or, to the Depositor’s knowledge, threatened against the Depositor in any court
or by or before any other governmental agency or instrumentality which would materially and adversely affect the validity of the
Mortgage Loans or the ability of the Depositor to carry out the transactions contemplated by this Agreement; and


 


(v)      The
Depositor is the lawful owner of the Mortgage Loans with the full right to transfer the Mortgage Loans to the Trust, and the Mortgage
Loans have been validly transferred to the Trust.


 


(b)       After
receipt of a Repurchase Request, the Enforcing Servicer 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 receipt of such notice of such Repurchase Request or, if earlier, such Mortgage Loan Seller’s discovery
of such Material Defect or (ii) in the case of a Material Defect relating to a Mortgage Loan not being a Qualified Mortgage,
the earlier of (x) discovery by the related Mortgage Loan Seller or any party to this Agreement of such Material Defect and
(y) receipt of notice of the Material


 






     -145-


     


    

 


Defect
from any party to this Agreement (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 or REO Loan (excluding any related Serviced 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 the Whole Loans, for which no substitution will be permitted) for such affected Mortgage
Loan or REO Loan (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) or substitute a Qualified
Substitute Mortgage Loan (other than with respect to the Whole Loans, for which no substitution will be permitted)); 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 Certificateholder or the Holder of the majority of the
Controlling Class, prior to the occurrence and continuance of a Consultation Termination Event) the Directing Certificateholder,
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 not cured after the Initial Cure Period and any such Extended Cure Period solely due to the
failure of the related Mortgage Loan Seller to have received the recorded document, then such Mortgage Loan Seller shall be entitled
to continue to defer its cure, repurchase and/or substitution obligations in respect of such Material Defect until eighteen (18)
months after the Closing Date for so long as such Mortgage Loan Seller certifies to the Trustee, the Master Servicer, the Special
Servicer and the Certificate Administrator no less than every ninety (90) days, beginning at the end of such Initial Cure Period,
that such Material Defect is still in effect solely because of its failure to have received the recorded document and that such
Mortgage Loan Seller is diligently pursuing the cure of such Material Defect (specifying the actions being taken). Notwithstanding
the foregoing, any Defect or Breach which causes any Mortgage Loan not to be a Qualified Mortgage shall be deemed to materially
and adversely affect the interests of Certificateholders


 






     -146-


     


    

 


therein, and (subject to the applicable Mortgage Loan Seller’s
right to cure such Defect or Breach during the Initial Cure Period) such Mortgage Loan shall be repurchased or substituted for
without regard to the Extended Cure Period described in the preceding sentence. If the affected Mortgage 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. In the event the Special Servicer is required to enforce the Repurchase
Request related to a Non-Specially Serviced Loan under this Section 2.03(b), within five (5) days of request by the Special
Servicer, the Master Servicer shall deliver to the Special Servicer a copy of the Servicing File with respect to any such Non-Specially
Serviced Loan.


 


If
a Mortgage Loan Seller, in connection with a Material Defect (or an allegation of a Material Defect) pertaining to a Mortgage
Loan, makes a cash payment pursuant to an agreement or a settlement between the applicable Mortgage Loan Seller and the Special
Servicer 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 an Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority
of the Controlling Class or a Servicing Shift Mortgage Loan), with the consent of the Directing Certificateholder or the Holder
of the majority of the Controlling Class, the consent of the Directing Certificateholder) (each such payment, a “Loss
of Value Payment”) with respect to such Mortgage 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. In connection with any
Loss of Value Payment with respect to any Non-Specially Serviced Loan, the Master Servicer shall promptly provide the Special
Servicer, but in any event within the time frames and in the manner provided in Section 3.19 (as if such Mortgage Loan
were subject to a Servicing Transfer Event), with the Servicing File and all information, documents and records relating to such
Non-Specially Serviced Loan and any related Serviced Companion Loan, either in the Master Servicer’s possession or otherwise
reasonably available to the Master Servicer, and reasonably required by the Special Servicer to permit the Special Servicer to
calculate the Loss of Value Payment, to the extent set forth in Section 3.19 (as if such Mortgage Loan were subject to
a Servicing Transfer Event). 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 of the Asset Representations Reviewer attributable to
the Asset Review of such Mortgage Loan and not previously paid by the Mortgage Loan Seller. 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 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 Special Servicer 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 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), (ii) such Loss of Value Payment
shall not be greater than the Purchase Price of the affected Mortgage Loan; and (iii) a Material Defect as a result of a
Mortgage Loan not constituting a Qualified Mortgage may not be cured by a Loss of Value Payment.


 






     -147-


     


    

 


If
any Breach that constitutes a Material Defect 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 shall 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) the amount of any fees payable by the Mortgage Loan Seller to the Asset Representations Reviewer 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 that in the event any such costs and expenses exceed $10,000, the 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,
a 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 (or make a Loss of Value Payment with respect to) for
the related Mortgage Loan if (i) the related Mortgage Loan Seller did not otherwise discover or have 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, 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 or possession of the Mortgage File), (iii) such delay precludes such Mortgage Loan Seller from curing such Material
Defect and (iv) such Material Defect does not relate to the applicable Mortgage Loan not being a Qualified Mortgage. Notwithstanding
the foregoing, if a Mortgage Loan is not secured by a Mortgaged Property that is, in whole or in part, a hotel, restaurant (operated
by a borrower), healthcare facility, nursing


 






     -148-


     


    

 


home,
assisted living facility, self-storage facility, theater or fitness center (operated by a borrower), then the failure to deliver
copies of the UCC Financing Statements with respect to such Mortgage Loan shall not be a 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 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 Material Defect: (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; (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, as applicable; (e) the absence from the Mortgage File of any
required letter of credit; or (f) with respect to any related leasehold Mortgage Loan, the absence from the related Mortgage
File of a copy (or an original, if available) of the related Ground Lease; provided, however, that no Defect (except
the Defects previously described in sub-clauses (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, establishing the validity or priority of any
lien on any collateral securing the related Mortgage Loan or for any immediate significant servicing obligation; provided,
further, that no Defect relating to any Non-Serviced Mortgage Loan previously described in sub-clauses (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


 






     -149-


     


    

 


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 5(a) 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 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, all portions of the Mortgage File and other documents pertaining to such Mortgage
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 or its designee in the same manner as provided in Section 5 of the related Mortgage Loan Purchase Agreement
and, if applicable, the definition of “Mortgage File” herein, so as to vest in such Mortgage Loan Seller or its designee
the legal and beneficial ownership of such repurchased or substituted Mortgage Loan (including property acquired in respect thereof
and proceeds of any insurance policy with respect thereto) and the related Mortgage Loan documents.


 


(e)       Section 5
of each of the Mortgage Loan Purchase Agreements and the provisions of this Section 2.03 provide 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 Material Defect; provided,
however, that the foregoing shall in no way limit the ability of the Special Servicer or the Trustee to take any action
against Ladder Capital Finance Holdings LLLP, Series REIT of Ladder Capital Finance Holdings LLLP or Series TRS of Ladder Capital
Finance Holdings LLLP, to the extent provided for pursuant to the related Mortgage Loan Purchase Agreement, including, without
limitation, pursuant to Section 19 thereof.


 






     -150-


     


    

 


(f)       The
Enforcing Servicer 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 the best interest of the Certificateholders
in accordance with the Servicing Standard. Any costs incurred by 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 Special Servicer 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)(vii) 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 that constitutes a Material Defect, which
also constitutes a default under the related Mortgage Loan 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 Rate, fees owed to the Master Servicer or 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 Enforcing 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 Enforcing Servicer determines in the exercise of its sole discretion consistent
with the Servicing Standard that such actions by it will not impair the Enforcing 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 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


 






     -151-


     


    

 


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 release, 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 Enforcing 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.


 






     -152-


     


    

 


(k)       (i)  In
the event an Initial Requesting Certificateholder delivers a written request to a party to this Agreement that a Mortgage Loan
be repurchased by the applicable Mortgage Loan Seller alleging the existence of a Material Defect with respect to such Mortgage
Loan and setting forth the basis for such allegation (a “Certificateholder Repurchase Request”), such party
shall promptly forward that Certificateholder Repurchase Request to the Enforcing Servicer, and the Enforcing Servicer shall promptly
forward the Certificateholder Repurchase Request to the related Mortgage Loan Seller and each other party to this Agreement. Subject
to Section 2.03(l), 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, the Operating
Advisor (solely in its capacity as operating advisor) or the Directing Certificateholder identifies a Material Defect with respect
to a Mortgage Loan (without implying any duty of such person to make, or to attempt to make, such a discovery), that party shall
deliver prompt written notice of such Material Defect to each other party to this Agreement and the related Mortgage Loan Seller
identifying the applicable Mortgage Loan and setting forth the basis for such allegation (a “PSA Party Repurchase Request”
and each of a Certificateholder Repurchase Request or a PSA Party Repurchase Request, the “Repurchase Request”)
and the Enforcing Servicer shall promptly send the PSA Party Repurchase Request to the related Mortgage Loan Seller. The Enforcing
Servicer shall act as the Enforcing 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 one hundred-eighty (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. A Resolved Repurchase Request shall not preclude the Special Servicer from exercising
any of its rights related to a Material Defect in the manner and timing otherwise set forth in this Agreement, in the related
Mortgage Loan Purchase Agreement or as provided by law


 


(l)        (i)  After
a Resolution Failure occurs with respect to a Repurchase Request regarding a Mortgage Loan (whether the Repurchase Request was
initiated by an Initial Requesting Certificateholder, a party to this Agreement or the Directing Certificateholder), the Enforcing
Servicer shall 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 will not be taken into consideration, (b) a statement


 



     -153-


     


    

 


that in the event any Certificateholder disagrees with the Proposed
Course of Action, the Enforcing Servicer (either as the Enforcing Party or as the Enforcing Servicer in circumstances where a
Certificateholder is acting as the Enforcing Party) shall be compelled to follow 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 Enforcing Servicer and the Certificate Administrator. 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 that clearly
indicate 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 responses of the responding Certificateholders and whether that amount constitutes a majority. 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 related Mortgage Loan Seller with respect to the Repurchase Request and 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 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 thirty (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 entitled to do so 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 for purposes of determining the course of action
approved by the majority of Certificateholders.


 


(ii)       If
neither the Initial Requesting Certificateholder, if any, nor any other Certificateholder or Certificate Owner entitled to do
so delivers a Preliminary Dispute


 



     -154-


     


    

 


Resolution Election Notice prior to the Dispute Resolution Cut-off Date, no Certificateholder
or Certificate Owner otherwise entitled to do so shall have the right to refer the Repurchase Request to mediation or arbitration,
and the Enforcing Servicer shall be the sole party entitled to determine a course of action, including, but not limited to, enforcing
the Trust’s rights against the related Mortgage Loan Seller, subject to any consent or consultation rights of the Directing
Certificateholder pursuant to Section 6.08.


 


(iii)      Promptly
and in any event within ten (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 shall 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 ten (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 appropriate relating to the timing and extent of such consultations.
No later than five (5) Business Days after completion of the Dispute Resolution Consultation, a Requesting Certificateholder may
provide a final 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 determine a course of action including, but not limited to, enforcing 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 shall collectively become the Enforcing Party, and the holder or holders
of a majority of the Voting Rights among such Requesting Certificateholders shall 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 thirty (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


 



     -155-


     


    

 


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; provided, however, that such Material Defect shall not be deemed waived with respect to a Requesting
Certificateholder, any other Certificateholder or Certificate Owner or the Enforcing Servicer to the extent there is a material
change in the facts and circumstances known to such party at the time when the Proposed Course of Action Notice is posted on the
Certificate Administrator’s Website, 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 as further described herein.


 


(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.


 


(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
within thirty (30) days of receipt of written notice of the Enforcing Party’s selection of mediation (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 admitted to practice in the state of New York and have at least fifteen (15) years
of experience in commercial litigation, and if possible, commercial real estate finance or commercial mortgage-backed securitization
matters 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 (10) potential qualified mediators by the Mediation Services Provider each party will have the right to


 



     -156-


     


    

 


exercise
two (2) 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)      Prior
to accepting an appointment, the mediator 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)      The
parties shall use commercially reasonable efforts to conduct an organizational conference to begin the mediation within ten (10)
Business Days of the selection of the mediator and to conclude the mediation within sixty (60) days thereafter.


 


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


 


(vi)      Out
of pocket costs and expenses of the Special Servicer for mediation or arbitration, to the extent not agreed to be paid by the
Enforcing Party or another party (in the case of mediation) or allocated to the Enforcing Party or another party (in the case
of arbitration) shall be reimbursable as a Servicing Advance.


 


(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 admitted to practice in the State of New York and have at least fifteen (15) years
of experience in commercial litigation, and if possible, commercial real estate finance or commercial mortgage-backed securitization
matters 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 (10) potential arbitrators by the Arbitration Services Provider each party will have the right to exercise
two (2) peremptory challenges within fourteen (14) days and to rank the remaining potential arbitrators in order of preference.
The Arbitration Services Provider will select the 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 ten (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


 



     -157-


     


    

 


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 thirty (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.


 


(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;


 



     -158-


     


    

 


(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 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

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 Certificateholder (provided
that a Consultation Termination Event has not occurred and is not continuing) 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 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

Request and the dispute resolution identified in connection with such procedures; provided, however, that (A) the
Certificateholders shall be permitted to communicate prior to the commencement of any such proceedings to the extent provided
in Section 5.06 and (B) the Enforcing Servicer shall be permitted to include such information in any 15Ga-1 Notice as it
is required pursuant to Section 2.02(g).


 


(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 or participation in such mediation or arbitration affect in any manner the ability of the Enforcing
Servicer to perform its obligations with respect to a Mortgage Loan (including without limitation, a liquidation, foreclosure,
negotiation of a loan modification or workout, acceptance of a discounted pay off or deed in lieu, or bankruptcy or other litigation)
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 or allocated to the Enforcing Servicer in a mediation or arbitration or related
responsibilities pursuant to this Agreement shall be reimbursable as additional Trust Fund expenses.

Section
3.01    The Master Servicer to Act as Master Servicer; Special Servicer to Act as Special Servicer; Administration of the

Servicer shall diligently service and administer the Mortgage Loans (other than any Non-Serviced Mortgage Loan), any related
Serviced Companion Loans and the REO Properties (other than any REO Property related to a Non-Serviced Mortgage Loan) it is
obligated (as provided below) to service in accordance with applicable law, this Agreement and the Mortgage Loan documents
and, in the case of a Serviced Whole Loan, the related Intercreditor Agreement on behalf of the Trust and in the best
interests of and for the benefit of the Certificateholders and, in the case of the Serviced Companion Loans, the Companion
Holders and the Trustee (as Holder of the Lower-Tier Regular Interests), as a collective whole, taking into account the
subordinate or pari passu nature of such Companion Loans (as determined by the Master Servicer or the Special
Servicer, as the case may be, in its reasonable judgment), in accordance with applicable law, the terms of this Agreement
(and, with respect to each Serviced Whole Loan or any Mortgage Loan with related mezzanine debt, the related Intercreditor
Agreement) and the terms of the respective Mortgage Loans and, if applicable, the related Companion Loan, taking into account
the subordinate or pari passu nature of the Companion Loan. With respect to each Serviced Whole Loan, in the event of
a conflict between this Agreement and the related Intercreditor Agreement, the related Intercreditor Agreement shall control; provided
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
action in accordance with the terms of any Intercreditor Agreement that would cause the Master Servicer or the Special
Servicer, as the case may be, to violate the Servicing Standard or the REMIC Provisions. To the extent consistent with the
foregoing, the Master Servicer and the Special Servicer shall service the Mortgage Loans (other than any
Non-Serviced Mortgage Loan) and the related Serviced Companion Loans in accordance with the higher of the following standards
of care: (1) in the same manner in which, and with the same care, skill, prudence and diligence with which the Master
Servicer or the Special Servicer, as the case may be, services and administers similar mortgage loans for other third party
portfolios and (2) the same care, skill, prudence and diligence with which the Master Servicer or the Special Servicer,
as the case may be, services and administers similar mortgage loans owned by the Master Servicer or the Special Servicer, as


 



     -161-


     


    

 


the case may be, with a view to the (A) the timely recovery of all payments of principal and interest under the Mortgage
Loans or Serviced Whole Loans or (B) in the case of a Specially Serviced Loan or an REO Property, maximization of
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, 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) a Non-Serviced Mortgage Loan and a Non-Serviced Companion Loan 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 or substitute
for a Mortgage 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) and 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 or Special Servicer Decision and (ii) any REO
Properties (other than the Non-Serviced Mortgaged Properties); provided that the Master Servicer shall continue to receive
payments and


 



     -162-


     


    

 


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 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, shall 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,
shall 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 and in accordance with the terms of this Agreement, 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 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, any related Serviced Companion Loans and any related Intercreditor Agreement, if applicable, and applicable
law, each of the Master Servicer and the Special Servicer shall have full power and authority, acting alone or, 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 (with respect to

(x) Special Servicer Decisions and Major Decisions on the
Mortgage Loans and (y) the Specially Serviced Loans and REO Properties), 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 and 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 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 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 Exhibit R-2 attached hereto, as applicable (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 Exhibit R-2
attached hereto, as applicable (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,


 



     -164-


     


    

 


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 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 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) (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) (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 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, 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 and that the Master Servicer or the Special Servicer shall service the related Mortgage
Loan for the benefit of the


 



     -165-


     


    

 


Certificateholders. The costs and expenses of any modifications to Ground Leases shall be paid by
the related Mortgagor.


 


With
respect to letters of credit delivered in accordance with subclause (B) of clause (xii) of the definition
of “Mortgage File”, (a) within sixty (60) days of the Closing Date or such shorter period as is required
by the terms of such letter of credit or other applicable Mortgage Loan documents, the related Mortgage Loan Seller shall notify
the bank issuing the letter of credit that the Master Servicer on behalf of the Trustee shall be the beneficiary under such letter
of credit, and (b) within sixty (60) days of the Closing Date, the Master Servicer shall present such letter of credit
and the related assignment documentation delivered by the Mortgage Loan Seller in accordance with such subclause of the definition
of “Mortgage File” to the letter of credit bank issuing such letter of credit and request that such letter of credit
bank reissue the letter of credit in the name of “Wells Fargo Bank, National Association, as Master Servicer, on behalf
of Wilmington Trust, National Association, as Trustee, for the benefit of registered holders of UBS Commercial Mortgage Trust
2017-C4, Commercial Mortgage Pass-Through Certificates, Series 2017-C4”. The Master Servicer shall otherwise use reasonable
efforts to obtain such reissued letter of credit back from the issuing letter of credit bank within sixty (60) days (and
in any event within ninety (90) days) following the Closing Date. The related Mortgage Loan Seller shall provide such reasonable
cooperation as requested by the Master Servicer, including without limitation by delivering such additional assignment or amendment
documents required by the issuing bank in order to reissue a letter of credit as provided above.


 


If
a letter of credit is required to be drawn upon earlier than the date that the letter of credit has been revised as contemplated
in the preceding sentence, such Mortgage Loan Seller shall 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.


 


The
Master Servicer acknowledges that any letter of credit held by it shall be held in its capacity as agent of the Trust, and if
the Master Servicer sells its rights to service the applicable Mortgage Loan, the Master Servicer shall assign the applicable
letter of credit to the Trust or (with respect to any Specially Serviced Loan) at the direction of the Special Servicer to such
party as the Special Servicer may instruct, in each case at the expense of the Master


 



     -166-


     


    

 


Servicer. The Master Servicer shall indemnify
the Trust for any loss caused by the ineffectiveness of such assignment.


 


(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 is contemplated by the related Intercreditor Agreement and, to the extent consistent with the related Intercreditor
Agreement, as any 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.


 


(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
Holder(s), in accordance with the respective outstanding principal balances of the related Serviced Pari Passu Mortgage Loan and
Serviced Pari Passu Companion Loan(s) or (ii) with respect to any Serviced AB Whole Loan, first, by the related AB
Subordinate Companion Loan(s) and then, pro rata and pari passu, by the Trust and any Serviced Pari Passu
Companion Loan(s), in accordance with the respective outstanding principal balances of the related Serviced Pari Passu Mortgage
Loan and Serviced Pari Passu Companion Loan(s).


 


(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


 



     -167-


     


    

 


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 Pari Passu 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 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-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


 



     -168-


     


    

 


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)       [RESERVED].


 


(o)       For
the avoidance of doubt, none of the Master Servicer, the Special Servicer, the Certificate Administrator and the Trustee have
any obligation or authority to (a) supervise any related Non-Serviced Master Servicer, Non-Serviced Special Servicer, Non-Serviced
Certificate Administrator or Non-Serviced Trustee or (b) make Servicing Advances with respect to any Non-Serviced Whole Loan.
The obligation of the Master Servicer to provide information and collections and make P&I Advances to the Certificate Administrator
for the benefit of the Certificateholders with respect to each Non-Serviced Mortgage Loan is dependent on its receipt of the corresponding
information and/or collections from the applicable Non-Serviced Master Servicer or Non-Serviced Special Servicer.


 


(p)       Nothing
contained in this Agreement shall limit the ability of the Master Servicer or the Special Servicer to lend money to (to the extent
not secured, in whole or in part, by any Mortgaged Property), accept deposits from and otherwise generally engage in any kind
of business or dealings with any Mortgagor as though the Master Servicer or the Special Servicer was not a party to this Agreement
or to the transactions contemplated hereby; provided that this sentence shall not be construed to modify or supersede the
Servicing Standard.


 


Section
3.02    Collection of Mortgage Loan Payments. (a)  The Master Servicer and the Special Servicer
shall each make reasonable efforts to collect all payments called for under the terms and provisions of the Mortgage Loans
(other than the Non-Serviced Mortgage Loans) and the Serviced 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, for 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 be permitted to take any enforcement action with respect to the failure of the related Mortgagor to
make any payment of Excess Interest to the extent permitted under the related Mortgage Loan documents; provided, further,
that the Master Servicer or the Special Servicer, as the case may be, may take action to enforce the 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 or Serviced Companion Loan three (3) times during any period of twenty-four (24) consecutive months with
respect to any Mortgage Loan or Serviced Companion Loan; provided that 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 or
Serviced Companion Loan one additional time in such 24-month period so long as with respect to any of the foregoing waivers,
no Advance or additional expense of the Trust has been incurred and remains unreimbursed to the Trust with respect to such
Mortgage Loan or Serviced Companion Loan. Any additional waivers during


 



     -169-


     


    

 


such 24-month period with respect to such Mortgage
Loan may be made, subject to the Servicing Standard, only after the Master Servicer or the Special Servicer, as the case may
be, has, prior to the occurrence and continuance of a Consultation Termination Event, given notice of a proposed waiver to
the Directing Certificateholder and, prior to the occurrence and continuance of a Control Termination Event, the Directing
Certificateholder has consented to such additional waiver (provided that if the Master Servicer or the Special
Servicer, as applicable, fails to receive a response to such notice from the Directing Certificateholder in writing within
five (5) days of giving such notice, then the Directing Certificateholder shall be deemed to have consented to such proposed
waiver); provided, further, that after the occurrence and during the continuance of a Control
Termination Event, the Master Servicer or the Special Servicer, as the case may be, may waive any Penalty Charge in
accordance with the Servicing Standard without the consent of the Directing Certificateholder; provided, further,
that the Directing Certificateholder shall not have any consent or consultation rights with respect to any Mortgage Loan that
is an Excluded Loan as to such party with respect to the foregoing waivers.


 


(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 (including any related Intercreditor Agreement); 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 a 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 such Mortgage
Loan and unpaid interest at the Reimbursement Rate on such Advances and, if applicable, unreimbursed and unpaid additional trust
fund expenses;


 


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 such Mortgage Loan (as described in the first proviso in the definition
of Principal Distribution Amount);


 


third,
to the extent not previously 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


 



     -170-


     


    

 


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, and (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 (in each case, 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;

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 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;


 



     -171-


     


    

 


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 of the related Companion Loan(s), as applicable, pursuant to 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 such 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 (as described in the first proviso in the definition
of Principal Distribution Amount);


 


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 or clause fifth of the prior paragraph 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


 



     -172-


     


    

 


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, 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 any) in the amount of related P&I Advances for such Mortgage Loan that have occurred in connection with related
Appraisal Reduction Amounts and (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 (in each case, to the extent collections
have not been allocated as recovery of accrued and unpaid interest pursuant to this clause fifth or clause fifth
of the prior paragraph on earlier dates);


 


sixth,
as a recovery of any Yield Maintenance Charge or Prepayment Premium 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 of any assumption fees and Modification Fees then due and owing under such Mortgage Loan;


 


ninth,
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); 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


 



     -173-


     


    

 


Proceeds or Liquidation Proceeds) and then paid by the Mortgagor under the Mortgage Loan or Companion
Loan, as applicable, or 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, as applicable, 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 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. 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)       In
connection with the Mortgage Loans or any Serviced Pari Passu Companion Loan for which the related Mortgagor was required to escrow
funds or to post a letter of credit related to obtaining performance objectives, such as targeted debt service coverage levels
or leasing criteria with respect to the Mortgaged Property as a whole or particular portions thereof, if the mortgagee has the
discretion under the applicable Mortgage Loan documents to retain the cash or letter of credit (or the proceeds of such letters
of credit) as additional collateral if the relevant conditions to release are not satisfied, then the related Master Servicer
may continue to hold such escrows or letters of credit (or the proceeds of such letters of credit) as additional collateral or
use such funds to reduce the principal balance of the related Mortgage Loan or Serviced Pari Passu Companion Loan (to the extent
the related Mortgage Loan documents allow such action), unless holding or application of such funds would otherwise be inconsistent
with the Mortgage Loan documents or the Servicing Standard.


 


(f)        Promptly
following the Closing Date, in the case of any Non-Serviced Whole Loan, and, with respect to the Servicing Shift Mortgage Loan,
promptly following receipt of notice in connection with the Servicing Shift Securitization Date, 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


 



     -174-


     


    

 


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 received by it shall be deposited and retained, and shall administer
such Servicing Accounts in accordance with the related Mortgage Loan documents and, if applicable, the Companion Loan
documents. Any Servicing Account related to a Serviced Whole Loan shall be held for the benefit of the Certificateholders and
the related Serviced Companion Noteholder(s) collectively, but this shall not be construed to modify the respective interests
of any 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, 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 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 related 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 related 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 related
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


 



     -175-


     


    

 


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, as applicable, and the Servicing Standard. To the extent that a
Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any related Companion Loan, as applicable, 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 such Mortgage Loans or Companion
Loan, as applicable, that it is responsible for servicing hereunder, shall use reasonable 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 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, as applicable, 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


 



     -176-


     


    

 


may make a Servicing Advance in its sole discretion. 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 the 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 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(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 in its reasonable judgment 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 instead 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, and such determination shall 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.
If the Master Servicer, the Special Servicer or the Trustee determines that a proposed Servicing Advance with respect to a Serviced
Mortgage Loan, if made, or any outstanding Servicing Advance with respect to a Serviced Mortgage Loan previously made, would be,
or is, as applicable, a Nonrecoverable Advance, the Master Servicer


 



     -177-


     


    

 


or the Trustee, as applicable, shall provide the applicable
Other Servicer written notice of such determination within two (2) Business Days of the date of such determination. 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, any related Serviced Companion Loan, if applicable, notwithstanding that the terms of
such Mortgage Loans, 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
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 the case may be) 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 the case may be, 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). The Master Servicer or the 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 the Master Servicer’s or Trustee’s 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 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), 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), 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.

behalf of it subsequent to the Cut-off Date (other than in respect of principal and interest on the Mortgage Loans or

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

(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, Prepayment Premiums,
Yield Maintenance Charges and Default Interest;

(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

Class, or the Holders of the Class R Certificates of all the Mortgage Loans and any REO Properties in the Trust Fund and

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;

(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 the Collection Account and then
withdrawn.


 



     -180-


     


    

 


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.


 


Upon
receipt of any of the foregoing amounts in clauses (i) through (iv) above with respect to any Specially Serviced

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 Wells Fargo Bank, National Association. The Master Servicer
shall give written 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.


 


(b)       The
Certificate Administrator, on behalf of the Trustee, shall establish and maintain (i) the Lower-Tier REMIC Distribution Account,
the Interest Reserve Account and the Gain-on-Sale Reserve Account in trust for the benefit of the Certificateholders (other than
Holders of the Excess Interest Certificates), (ii) the Upper-Tier REMIC Distribution Account in trust for the benefit of
the Certificateholders (other than the Holders of the Excess Interest Certificates) and (iii) the Excess Interest Distribution
Account in trust for the benefit of the Holders of the Excess Interest Certificates. The Master Servicer shall deliver to the
Certificate Administrator each month on or before the P&I Advance Date therein, for deposit (x) in the Lower-Tier REMIC
Distribution Account, that portion of the Available Funds attributable to the Mortgage Loans (in each case, calculated without
regard to clauses (a)(iii)(B), (a)(iv), (c) and (d) of the definition of Available Funds) for
the related Distribution Date and (y) in the Excess Interest Distribution Account all Excess Interest for the related Distribution
Date then on deposit in the Collection Account maintained by the Master Servicer after giving effect to withdrawals of funds pursuant

Administrator, all funds held in the Distribution Account, the Interest Reserve Account and the Excess Interest Distribution Account
shall remain uninvested.


 



     -181-


     


    

 


With
respect to any ARD Loans in the Trust Fund, the Certificate Administrator shall, on any Distribution Date, make withdrawals from
the Excess Interest Distribution Account to the extent required to make the distributions of Excess Interest required by Section
4.01(j) of this Agreement.


 


With
respect to each Companion Loan (excluding any Non-Serviced Companion Loan), the Companion Paying Agent shall establish and maintain
the Companion Distribution Account, which may be a subaccount of the Collection Account, for distributions to each Companion Holder.
Funds in the Companion Distribution Account shall be held for the benefit of the related Companion Holder. The Companion Paying
Agent shall separately track for each Serviced Companion Loan all amounts deposited in the Companion Distribution Account with
respect to such Serviced Companion Loan.


 


On
each Serviced Whole Loan Remittance Date, (1) first, the Master Servicer shall withdraw from the Collection Account (or applicable
portion thereof) an aggregate amount equal to all payments and/or collections actually received on, and payable in respect of,
the applicable Serviced Companion Loan prior to such date and deposit such amount in the Companion Distribution Account; provided,
however, that in no event shall the Master Servicer be required to transfer to the Companion Distribution Account any portion
thereof that is payable or reimbursable to or at the direction of any party to this Agreement under the other provisions of this
Agreement and/or the related Intercreditor Agreement; and (2) then, the Companion Paying Agent shall make the payments and
remittance described in Section 4.01(k). With respect to any Serviced Whole Loan, in the event the Master Servicer has
received written notice that an Other Servicer or Other Trustee has made an advance of a monthly debt service payment on a related
Serviced Pari Passu Companion Loan and the Master Servicer subsequently receives Late Collections in respect of such advanced
payment, the Master Servicer shall remit to the applicable Other Servicer or Other Trustee, within two (2) Business Days following
receipt of such Late Collections in properly identified funds, the amount allocable to such Serviced Pari Passu Companion Loan
in accordance with the terms of this Agreement and the related Intercreditor Agreement.


 


The
Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Excess Interest Distribution Account, the
Gain-on-Sale Reserve Account and the Interest Reserve Account, may be subaccounts of a single Eligible Account, which shall be

than the portion of any Compensating Interest Payment allocated to a Serviced Pari Passu Companion Loan) in connection with Prepayment
Interest Shortfalls;


 



     -182-


     


    

 


(ii)       any
P&I Advances required to be made by the Master Servicer in accordance with Section 4.03;


 


(iii)      any
Liquidation Proceeds paid by the Master Servicer, the Special Servicer, the Holders of the Controlling Class or the Holders of
the Class R Certificates in connection with the purchase of all of the Mortgage Loans and any REO Properties in the Trust
Fund pursuant to Section 9.01 (exclusive of that portion thereof required to be deposited in the Collection Account pursuant
to Section 9.01);


 


(iv)     any
Prepayment Premiums and Yield Maintenance Charges with respect to the Mortgage Loans actually collected; and


 


(v)      any
other amounts required to be so delivered for deposit in the Lower-Tier REMIC Distribution Account pursuant to any provision of
this Agreement.


 


If,
as of the close of business (New York City time) on any P&I Advance Date or on such other date as any amount referred to in
the foregoing clauses (i) through (v) or any Excess Interest are required to be delivered hereunder, the Master
Servicer shall not have delivered to the Certificate Administrator for deposit in the Lower-Tier REMIC Distribution Account or
the Excess Interest Distribution Account, as applicable, the amounts required to be deposited therein pursuant to the provisions
of this Agreement (including any P&I Advance with respect to the Mortgage Loans, pursuant to Section 4.03(a)), the
Master Servicer shall pay the Certificate Administrator interest on such late payment at the Prime Rate from and including the
date such payment was required to be made (without regard to any Grace Period set forth in Section 7.01(a)(i)) until (but
not including) the date such late payment is received by the Certificate Administrator.


 


The
Certificate Administrator shall, upon receipt, deposit in the Lower-Tier REMIC Distribution Account or the Excess Interest Distribution
Account, as applicable, any and all amounts received by the Certificate Administrator that are required by the terms of this Agreement
to be deposited therein.


 


Promptly
on each Distribution Date, the Certificate Administrator shall be deemed to withdraw from the Lower-Tier REMIC Distribution Account
and deposit in the Upper-Tier REMIC Distribution Account an aggregate amount of immediately available funds equal to the Lower-Tier
Distribution Amount and the amount of any Prepayment Premiums and Yield Maintenance Charges for such Distribution Date allocated
in payment of the Lower-Tier Regular Interests as specified in Section 4.01(c) and Section 4.01(e), respectively.


 


Funds
on deposit in the Gain-on-Sale Reserve Account, the Interest Reserve Account, the Excess Interest Distribution Account, the Upper-Tier
REMIC Distribution Account, the Lower-Tier REMIC Distribution Account shall not be invested for so long as Wells Fargo Bank, National
Association is the Certificate Administrator; provided, however, that such funds may be invested and, if invested,
shall be invested by, and at the risk of, the Certificate Administrator (but only if the Certificate Administrator is not Wells
Fargo Bank, National Association) in Permitted Investments selected by the party hereunder that maintains such account which shall
mature, unless payable on demand, not later than such time on the


 



     -183-


     


    

 


Distribution Date which will allow the Certificate Administrator
to make withdrawals from the Distribution Account, and any such Permitted Investment shall not be sold or disposed of prior to
its maturity unless payable on demand. All such Permitted Investments to be administered by the Certificate Administrator, shall
be made in the name of “Wells Fargo Bank, National Association, as Certificate Administrator, for the benefit of Wilmington
Trust, National Association, as Trustee for the Holders of the UBS Commercial Mortgage Trust 2017-C4, Commercial Mortgage Pass-Through
Certificates, Series 2017-C4 as their interests may appear”, or in the name of any successor trustee, as Trustee for the
Holders of the UBS Commercial Mortgage Trust 2017-C4, Commercial Mortgage Pass-Through Certificates, Series 2017-C4 as their interests
may appear. None of the Trust, the Depositor, the Mortgagors, the Master Servicer or the Special Servicer shall be liable for
any loss incurred on such Permitted Investments.


 


An
amount equal to all income and gain realized from any such investment shall be paid to the Certificate Administrator as additional
compensation and shall be subject to its withdrawal at any time from time to time. The amount of any losses incurred in respect
of any such investments shall be for the account of the Certificate Administrator which shall deposit the amount of such loss
(to the extent not offset by income from other investments) in the Distribution Accounts, as the case may be, out of its own funds
immediately as realized. If the Certificate Administrator deposits in or transfers to the Distribution Accounts, as the case may
be, any amount not required to be deposited therein or transferred thereto, it may at any time withdraw such amount or retransfer
such amount from the Distribution Accounts, as the case may be, any provision herein to the contrary notwithstanding.


 


On
the Closing Date, the Depositor shall deposit $275,000 with the Certificate Administrator, to be credited to the Legal Fee Reserve
Account. Funds held in the Legal Fee Reserve Account shall remain uninvested. Annually, on or about April 1st beginning
2018, upon receipt by the Certificate Administrator from the Depositor of a legal invoice related to Commission compliance matters,
the Certificate Administrator shall pay such legal invoice from and solely to the extent of funds then on deposit in the Legal
Fee Reserve Account. Any such instruction shall be sent by email to cts.cmbs.bond.admin@wellsfargo.com, along with a copy of the
invoice, and a subject line reference of “UBS 2017-C4 - Legal Fee Reserve Account”. The Legal Fee Reserve Account
will not be a part of the Trust Fund or any Trust REMIC. The Depositor will be the beneficial owner of the Legal Fee Reserve Account
for all federal income tax purposes, and shall be taxable on all income earned therefrom.


 


Upon
the depletion of the Legal Fee Reserve Account, or if there are insufficient funds to pay any invoice, the Certificate Administrator
shall notify the Depositor, and thereafter the Depositor shall pay any additional legal invoices from its own funds and the Certificate
Administrator shall have no responsibility in connection therewith.


 


The
Certificate Administrator shall have no responsibility for verifying the accuracy, reasonableness, or appropriateness of any invoice
received. On the final Distribution Date, the Certificate Administrator shall pay to the Depositor any funds then remaining in
the Legal Fee Reserve Account in accordance with directions provided by the Depositor.

of the Closing Date, the Interest Reserve Account, the Excess Interest Distribution Account, the Upper-Tier REMIC Distribution
Account, the Lower-Tier REMIC


 






     -184-

Administrator shall give notice to the Trustee, the Master Servicer, and the Depositor of the proposed location of the Interest
Reserve Account, the Excess Interest Distribution Account, the Upper-Tier REMIC Distribution Account, the Lower-Tier REMIC Distribution
Account, and, if established and the Gain-on-Sale Reserve Account prior to any change thereof.

the avoidance of doubt, the Collection Account (other than (i) any portion holding Excess Interest and (ii) the Companion
Distribution Account, if it is a sub-account of the Collection Account), the Lower-Tier REMIC Distribution Account, the Gain-on-Sale
Reserve Account, any Servicing Account, the REO Account and the Interest Reserve Account (including interest, if any, earned on
the investment of funds in such accounts) will be owned by the Lower-Tier REMIC; the Excess Interest Distribution Account (and
any portion of the Collection Account holding Excess Interest) (including interest, if any, earned on the investment of funds
in such account) will be owned by the Grantor Trust for the benefit of the Holders of the Excess Interest Certificates; the Companion
Distribution Account (including interest, if any, earned on the investment of funds in such account) will be owned by the Companion
Holders; and the Upper-Tier REMIC Distribution Account (including interest, if any, earned on the investment of funds such account)

(c)       Prior
to any Determination Date for the first Collection Period during which Excess Interest is received on any Mortgage Loan, and upon
notification from the Master Servicer or Special Servicer pursuant to Section 3.02(d), the Certificate Administrator, on
behalf of the Certificateholders, shall establish and maintain the Excess Interest Distribution Account in its own name on behalf
of the Trustee in trust for the benefit of the Holders of the Excess Interest Certificates. The Excess Interest Distribution Account
shall be established and maintained as an Eligible Account (or as a subaccount of an Eligible Account). Prior to the applicable
Distribution Date, the Master Servicer shall remit to the Certificate Administrator for deposit in the Excess Interest Distribution
Account an amount equal to the Excess Interest received by the Master Servicer prior to the Determination Date for the applicable
Collection Period.


 


(d)       Following
the distribution of the applicable portions of Excess Interest to Holders of the Excess Interest Certificates on the first Distribution
Date after which there are no longer any Mortgage Loans outstanding which pursuant to their terms could pay Excess Interest, the
Certificate Administrator shall terminate the Excess Interest Distribution Account.


 


(e)       The
Certificate Administrator shall establish (upon notice from the Special Servicer of an event occurring that generates Gain-on-Sale
Proceeds) and maintain the Gain-on-Sale Reserve Account for the benefit of the Certificateholders. The Gain-on-Sale Reserve Account
shall be maintained as an Eligible Account (or as a subaccount of an Eligible Account), separate and apart from trust funds for
mortgage pass-through certificates of other series administered by the Certificate Administrator.


 


Upon
the disposition of any REO Property, in accordance with Section 3.09 or Section 3.16, the Special Servicer will
calculate the Gain-on-Sale Proceeds, if any, realized that are allocable to the Mortgage Loan in connection with such sale and
remit such funds to the Certificate Administrator for deposit into the Gain-on-Sale Reserve Account. Any gain on such


 



     -185-


     


    

 


disposition
that is allocable to any related Companion Loan in accordance with the terms of the related Intercreditor Agreement shall be remitted
to the Companion Paying Agent for deposit into the Companion Distribution Account.


 


(f)       Any
Non-Serviced Gain-on-Sale Proceeds received with respect to any Non-Serviced Mortgage Loan pursuant to the related Non-Serviced
PSA shall be remitted to the Certificate Administrator for deposit into the Gain-on-Sale Reserve Account.

(h)       [RESERVED].


 


(i)        If
any Loss of Value Payments are received in connection with a Material Defect pursuant to or as contemplated by Section 3.05(g)
of this Agreement, the Special Servicer shall establish and maintain one or more non-interest bearing accounts (collectively,
the “Loss of Value Reserve Fund”) to be held for the benefit of the Certificateholders, for purposes of holding
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, within two (2) Business Days of receipt of properly identified and available
Loss of Value Payments, deposit in the Loss of Value Reserve Fund all Loss of Value Payments received by it. The Certificate Administrator
shall account for the Loss of Value Reserve Fund as an outside reserve fund within the meaning of Treasury Regulations Section 1.860G-2(h)
and not an asset of any Trust REMIC or the Grantor Trust. Furthermore, for all federal tax purposes, the Certificate Administrator
shall (i) treat amounts paid out of the Loss of Value Reserve Fund through the Collection Account to the Certificateholders
as paid to and distributed by the Trust REMICs and (ii) treat any amounts paid out of the Loss of Value Reserve Fund through
the Collection Account to a Mortgage Loan Seller as distributions by the Trust to such Mortgage Loan Seller as beneficial owner
of the Loss of Value Reserve Fund. The applicable Mortgage Loan Seller will be the beneficial owner of the Loss of Value Reserve
Fund for all federal income tax purposes, and shall be taxable on all income earned thereon.

(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 the case may be, 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, the 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 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 the case may be, 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


 



     -197-


     


    

 


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, Loss of Value Reserve Fund 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, the 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 Special Servicer, as the case
may be, would have been entitled to any Net Investment Earnings hereunder) directed to be made by the Master Servicer or the Special
Servicer, as the case may be, 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, the 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 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, such federal or state chartered depository


 



     -198-


     


    

 


institution or
trust company is not an Affiliate of the Master Servicer 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 more than 50% 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)  The Master
Servicer (with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan)
shall use its 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, to the extent required by the terms of the related Mortgage Loan documents, 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
the case may be). 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 the related Mortgage, 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, as applicable,
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 Certificateholder (prior to
the occurrence and continuance of any Control Termination Event and other than with respect to any Excluded Loan as to the Directing
Certificateholder) (or, with respect to any Serviced AB Whole Loan, if the Directing Certificateholder’s consent is required
and prior to the occurrence and continuance of a related AB Control Appraisal Period, with the consent of the Serviced AB Whole
Loan Controlling Holder) 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 Certificateholder 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 Master Servicer (with respect to a Non-Specially Serviced
Loan) or the Special Servicer (with respect to a Specially Serviced Loan); provided, however, that if any Mortgage
permits the holder thereof to dictate to the Mortgagor the insurance coverage to be maintained on such Mortgaged Property, the
Master Servicer or, with


 



     -199-


     


    

 


respect to 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, provided 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 Master Servicer (with respect to a Non-Specially Serviced Loan) or the Special Servicer (with respect to
a Specially Serviced Loan) with the consent of the Directing Certificateholder (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 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 Certificateholder (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 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


 



     -200-


     


    

 


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 will not be required to maintain, and will 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 (other than a Non-Serviced 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, 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 shall be entitled to conclusively rely upon 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) if the related Mortgage Loan is a Specially Serviced Loan, 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 clauses (A) and (B) above) that any Mortgagor under a Specially Serviced
Loan fails to purchase the insurance requested to be purchased by the Master Servicer pursuant to clause (B) above.
If the Master Servicer (with respect to a Non-Specially Serviced Loan) or the Special Servicer (with respect to a Specially Serviced
Loan) determines in accordance with the Servicing Standard that such failure is not an Acceptable Insurance Default, the Special
Servicer (with regard to such determination made by the Special Servicer) shall notify the Master Servicer and the Master Servicer
shall use efforts


 



     -201-


     


    

 


consistent with the Servicing Standard to cause such insurance to be maintained. The Master Servicer and 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 the Master Servicer) in determining
whether Additional Exclusions exist. Furthermore, the Master Servicer or the Special Servicer, as applicable, 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 Master Servicer or the Special Servicer is evaluating the availability
of such insurance or waiting for a response from the Directing Certificateholder or (solely with respect to Specially Serviced
Loans) upon the request of the Risk Retention Consultation Party, consulting (on a non-binding basis) 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 will not
be in default of its obligations as a result of such failure 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. The Special Servicer,
to the extent 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.


 



     -202-


     


    

 


(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)       The
Master Servicer and the Special Servicer shall each 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
losses that may be sustained as a result of an officer’s or employee’s misappropriation of funds or errors or omissions.
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,
and will furnish to the Trustee copies of all binders and policies or certificates evidencing 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 such insurance is available at commercially
reasonable rates (as determined by the Master Servicer in


 



     -203-


     


    

 


accordance with the Servicing Standard and to the extent the Trustee,
as mortgagee, has an insurable interest therein), flood insurance in respect thereof, 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. 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. 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 Certificateholder (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 and any
Serviced AB Whole Loan prior to the occurrence and during the continuance of a Control Appraisal Period)) 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, plus such additional excess flood coverage with respect to the Mortgaged Property, if any, in an amount
consistent with the Servicing Standard. 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)        Notwithstanding
the foregoing, so long as the long-term debt obligations or the deposit account 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 (if rated by Moody’s) or “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 any of its obligations under this Section 3.07.


 


(g)       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:


 



     -204-


     


    

 


(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 Master Servicer
(with respect to any Non-Specially Serviced Loan as to which such matter is a Master Servicer Decision pursuant to clause (xiii)
of the definition thereof) or the Special Servicer (with respect to any Specially Serviced Loan or any Non-Specially Serviced
Loan as to which such matter is a Major Decision or Special Servicer Decision), 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 (i) other than with respect to a Master Servicer Decision pursuant to
clause (xiii) of the definition thereof, (A) if such Mortgage Loan is not an Excluded Loan with respect to the Directing
Certificateholder, no Control Termination Event shall have occurred and be continuing and the matter involves a Major Decision,
the consent (or deemed consent) of the Directing Certificateholder shall have been obtained by the Special Servicer to the extent
required by, and pursuant to the process described under, Section 6.08(a), (B) if such Mortgage Loan is not an Excluded
Loan with respect to the Directing Certificateholder, a Control Termination Event shall have occurred and be continuing and no
Consultation Termination Event shall have occurred and be continuing, the Special Servicer shall have consulted with the Directing
Certificateholder if and to the extent required pursuant to Section 6.08(a) and (C) if such Mortgage Loan is not an Excluded
Loan with respect to the Risk Retention Consultation Party and (x) such Mortgage Loan is a Specially Serviced Loan or (y) a Consultation
Termination Event shall have occurred and be continuing, the Special Servicer shall have consulted with the Risk Retention Consultation
Party if and to the extent required pursuant to Section 6.08(a) (provided that in the case of clause (A),
clause (B) and clause (C) such consent shall be deemed given or such consultation shall be deemed to have occurred,
as applicable, if a response to the request for consent or consultation, as the case may be, is not provided within ten (10) Business
Days after receipt of the Special Servicer’s written recommendation and analysis and all information reasonably requested
by the Directing Certificateholder or the Risk Retention Consultation Party, as applicable, and reasonably available to such Special
Servicer in order to grant or withhold such consent or conduct such consultation), and (ii) with respect to any Mortgage
Loan (x) with a Stated Principal Balance greater than or equal to $20,000,000, (y) with a Stated Principal Balance greater
than or equal to 5% of the aggregated Stated Principal Balance of the Mortgage Loans then outstanding or (z) 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 (10) largest Mortgage Loans outstanding (by Stated Principal
Balance), 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


 



     -205-


     


    

 


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 sub-clauses (y) and (z) of this sub-clause (ii), 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 Certificateholder or the Holder
of the majority of the Controlling Class (regardless of whether a Control Termination 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.


 


With
respect to any “due-on-sale” matter described above that is a Major Decision related to any Mortgage Loan that is
not an Excluded Loan with respect to the Risk Retention Consultation Party or the holder of the majority of the RR Interest, upon
request of the Risk Retention Consultation Party, the Special Servicer shall consult on a non-binding basis with the Risk Retention
Consultation Party with respect to (i) prior to the occurrence and continuance of a Consultation Termination Event, Specially

In
connection with any request for a Rating Agency Confirmation from a Rating Agency (or, with respect to any Serviced Companion

that is processing the related action, as the case may be, 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
contained in the related Mortgage Loan documents are satisfied where no mortgagee discretion is necessary in order to determine
if such conditions are satisfied, then for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced
under this Agreement, the Master Servicer (with respect to all Non-Specially Serviced Loans) and the Special Servicer (with respect
to all Specially Serviced 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.


 


(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:


 



     -206-


     


    

 


(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 or related Serviced Companion Loan is being serviced under this Agreement, the Master
Servicer (with respect to any Non-Specially Serviced Loan and as to which such matter is a Master Servicer Decision pursuant
to clause (xiii) or clause (xv) of the definition thereof) or the Special Servicer (with respect to any
Specially Serviced Loan or any Non-Specially Serviced Loan as to which such matter is a Major Decision or Special Servicer
Decision), 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 (i) other than with respect to a Master Servicer Decision pursuant to clause (xiii)
or clause (xv) of the definition thereof, (A) if such Mortgage Loan is not an Excluded Loan with respect to the
Directing Certificateholder, no Control Termination Event shall have occurred and be continuing and the matter involves a
Major Decision, the consent (or deemed consent) of the Directing Certificateholder shall have been obtained by the Special
Servicer to the extent required by, and pursuant to the process described under, Section 6.08(a), (B) if such
Mortgage Loan is not an Excluded Loan with respect to the Directing Certificateholder, a Control Termination Event shall have
occurred and be continuing, and no Consultation Termination Event shall have occurred and be continuing, the Special Servicer
shall have consulted with the Directing Certificateholder if and to the extent required pursuant to Section 6.08(a)
and (C) if such Mortgage Loan is not an Excluded Loan with respect to the Risk Retention Consultation Party and (x) such
Mortgage Loan is a Specially Serviced Loan or (y) a Consultation Termination Event shall have occurred and be continuing, the
Special Servicer shall have consulted with the Risk Retention Consultation Party if and to the extent required pursuant to Section
6.08(a) (provided that in the case of clause (A), clause (B) and clause (C) such
consent shall be deemed given or such consultation shall be deemed to have occurred, as applicable, if a response to the
request for consent or consultation, as the case may be, is not provided within ten (10) Business Days after receipt of
the Special Servicer’s written recommendation and analysis and all information reasonably requested by the Directing
Certificateholder or the Risk Retention Consultation Party, as applicable, and reasonably available to such Special Servicer
in order to grant or withhold such consent or conduct such consultation), and (ii) such Master Servicer or such Special
Servicer, as the case may be, 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 or (B) has
an LTV Ratio greater than 85%


 






     -207-


     


    

 


(including any
existing and proposed debt) or (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) or (D) is one of the ten largest Mortgage Loans (by Stated Principal Balance) or (E) has
a Stated Principal Balance greater than $20,000,000; provided, however, that with respect to sub-clauses (A),
(B), (C) and (D) of this sub-clause (ii), 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 Certificateholder (regardless of whether a Control Termination
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.


 


With
respect to any “due-on-encumbrance” matter described above that is a Major Decision related to any Mortgage Loan that
is not an Excluded Loan with respect to the Risk Retention Consultation Party or the holder of the RR Interest, upon request of
the Risk Retention Consultation Party, the Special Servicer shall consult on a non-binding basis with the Risk Retention Consultation
Party with respect to (i) prior to the occurrence and continuance of a Consultation Termination Event, Specially Serviced Loans;
and (ii) following the occurrence and during the continuance of a Consultation Termination Event, all Mortgage Loans, within the
same time period as it would obtain the consent of, or consult with, the Directing Certificateholder with respect to the above

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 contained in the related Mortgage Loan documents
are satisfied where no mortgagee discretion is necessary in order to determine if such conditions are satisfied, then for so long
as such Mortgage Loan or related Companion Loan is being serviced under this Agreement, the Master Servicer (with respect to all
Non-Specially Serviced


 






     -208-


     


    

 


Loans) and the Special Servicer (with respect to all Specially Serviced Loans), on behalf of the Trustee
as the mortgagee of record, shall determine whether such conditions have been satisfied.


 


Upon
receiving a request for any matter described in Section 3.08(a) or this Section 3.08(b) that constitutes a
consent or waiver with respect to a “due-on-sale” or “due-on-encumbrance” clause with respect to a
Mortgage Loan that is a Non-Specially Serviced Loan and other than any transfers provided for in clause (xiii) of
the definition of Master Servicer Decision and other than any waiver of a “due-on-encumbrance” clause which
waiver constitutes a Master Servicer Decision pursuant to clause (xiii) of the definition thereof, the Master
Servicer shall promptly forward such request to the Special Servicer and the Special Servicer shall process such request
(including, without limitation, interfacing with the Mortgagor) and except as provided in the next sentence, the Master
Servicer will have no further obligation with respect to such request or due-on-sale or due-on-encumbrance. The Master
Servicer shall continue to cooperate with the Special Servicer by delivering to the Special Servicer any additional
information in the Master Servicer’s possession requested by the Special Servicer relating to such consent or waiver
with respect to a “due-on-sale” or “due-on-encumbrance” clause. The Master Servicer shall not be
permitted to process any request relating to such consent or waiver with respect to a “due-on-sale” or
“due-on-encumbrance” clause (other than any transfers or assumptions provided for in clause (xiii)
of the definition of Master Servicer Decision and other than any waiver of a “due-on-encumbrance” clause
which waiver constitutes a Master Servicer Decision pursuant to clause (xiii) of the definition thereof) and
shall not be required to interface with the Mortgagor or provide a written recommendation and analysis with respect to any
such request.


 


(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 the case may be, 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)          [RESERVED].


 


(f)          For
the avoidance of doubt, neither the Master Servicer nor the Special Servicer may waive its rights or grant its consent under any
“due-on-sale” or


 






     -209-


     


    

 


“due-on-encumbrance”
clause other than in compliance with the provisions of Section 3.08(a) through (d) hereof. In the case of
the Special Servicer, no such waiver or consent shall be made without (x) (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 Certificateholder, the consent (or deemed consent) of the Directing Certificateholder having been obtained if and
to the extent required by, and pursuant to the process described under Section 6.08(a), (y) (i) after the
occurrence and during the continuance of a Control Termination Event and (ii) other than with respect to any
Excluded Loan with respect to the Directing Certificateholder, but prior to the occurrence and continuance of a Consultation
Termination Event, after having consulted with the Directing Certificateholder if and to the extent required pursuant to Section
6.08(a) or (z) with respect to a Serviced AB Whole Loan, prior to the occurrence and continuance of a related AB Control
Appraisal Period, the consent of the AB Whole Loan Controlling Holder.


 


(g)          Notwithstanding
the foregoing provisions of this Section 3.08, if the Master Servicer or the Special Servicer, as applicable, makes a determination
under Sections 3.08(a) or 3.08(b) 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).


 


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 Certificateholder’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 or the Special Servicer, as applicable, for such 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


 






     -210-


     


    

 


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


 






     -211-


     


    

 


(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, 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 4 of each of the Mortgage Loan Purchase Agreements for which the applicable Mortgage
Loan Seller (or, in the case of Ladder Capital Finance LLC, Ladder Capital Finance Holdings LLLP, Series REIT of Ladder Capital
Finance Holdings LLLP and Series TRS of Ladder Capital Finance Holdings LLLP in respect of their respective payment guaranties)
could be required to repurchase such Defaulted Loan pursuant to Section 5 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 the consent of the Directing Certificateholder and
after consultation with the Risk Retention Consultation Party pursuant to


 






     -212-


     


    

 


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 Certificateholder and the Risk Retention Consultation Party (in the case of the Directing Certificateholder, prior
to the occurrence and continuance of a Consultation Termination Event, and in the case of the Directing Certificateholder 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 Certificateholder
as required above, the Holders of Certificates entitled to more than 50% 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
Certificateholder 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 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


 






     -213-


     


    

 


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 Certificateholder
and the Risk Retention Consultation Party (but in the case of the Directing Certificateholder 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 Certificate Administrator to Cooperate; Release of Mortgage Files. (a)  Upon
the payment in full of any Mortgage 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 seven (7) 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


 






     -214-


     


    

 


and that all amounts received or to be received in connection with such liquidation
which are 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
seven (7) 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
Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note (including any note evidencing
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.


 


(d)          If,
from time to time, pursuant to the terms of the applicable Non-Serviced Intercreditor Agreement and the applicable Non-Serviced
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 calculated on such Mortgage Loan, Companion Loan or REO 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 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,


 






     -215-


     


    

 


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 following sentence, the fourth (4th) 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 Loan, to the extent not prohibited by the related Intercreditor Agreement) that are
Master Servicer Decisions; and for any matter for a Mortgage Loan (including any related Companion Loan) that is not a Specially
Serviced Loan which matter involves a Major Decision or a Special Servicer Decision, then the Master Servicer shall be entitled
to 50% of such Excess Modification Fees,


 


(ii) 100%
of all assumption application fees and other similar items received on any Mortgage Loans (other than a Non-Serviced Mortgage
Loan) that are Non-Specially Serviced Loans (including any related Serviced Companion Loan, to the extent not prohibited by the
related Intercreditor Agreement) to the extent the Master Servicer is processing the underlying transaction and 100% of all defeasance
fees (provided that for the avoidance of doubt, any such defeasance fee shall not include any Modification Fees in connection
with a defeasance that the Special Servicer is entitled to under this Agreement); and


 


(iii) 100%
of assumption, waiver, consent and earnout fees, and other similar fees (other than assumption application and defeasance 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)
relating to Master Servicer Decisions; and for any matter for a Mortgage Loan (including any related Companion Loan) that is not
a Specially Serviced Loan which matter involves a Major Decision or a Special Servicer Decision, then the Master Servicer shall
be entitled to 50% of such assumption, waiver, consent and earnout fees and other similar fees.


 






     -216-


     


    

 


In
addition, the Master Servicer shall be entitled to charge and retain as additional servicing compensation (other than with respect
to any Non-Serviced Mortgage Loan or Specially Serviced Loan) any charges for beneficiary statements or demands and other customary
charges, amounts collected for checks returned for insufficient funds and reasonable review fees in connection with any Mortgagor
request to the extent such review fees are not prohibited under the related Mortgage Loan documents, in each case only to the
extent actually paid by or on behalf of the related Mortgagor and shall not be required to deposit such amounts in the Collection
Account or the Companion Distribution Account pursuant to Section 3.04(a) or Section 3.04(b), respectively. 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 its Servicing Accounts which are not required by applicable law or the related Mortgage Loan
to be paid to the Mortgagor, and (iv) the difference, if positive, between Prepayment Interest Excesses and Prepayment Interest
Shortfalls collected on the Mortgage 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 (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. Similarly, if the Special Servicer decides not to charge any fee, the Master Servicer shall nevertheless
be entitled to charge its portion of the related fee to which the Master Servicer would have been entitled if the Special Servicer
had charged a fee and the Special Servicer shall not be entitled to any portion of such fee charged by the Master Servicer.


 


Notwithstanding
anything herein to the contrary, Wells Fargo Bank, National Association may, at its option, assign or pledge to any third party
or retain for itself the Transferable Servicing Interest with respect to any Mortgage Loan and any Serviced Pari Passu


 






     -217-


     


    

 


Companion
Loan (and any successor REO Loan); provided, however, that in the event of any resignation or termination of the
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 Wells Fargo Bank, National Association, as
Master Servicer, 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. 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)          The
Special Servicer shall be entitled to 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 and other similar items received with respect to Specially Serviced Loans and 100% of all assumption
application fees and other similar items received with respect to Mortgage Loans (other than Non-Serviced Mortgage Loans) and
Serviced Companion Loans that are Non-Specially Serviced Loans to the extent the Special Servicer processes the underlying transaction,


 


(iii)          100%
of waiver, consent and earnout fees, or other actions performed in connection with this Agreement on the Specially Serviced Loans
or certain other similar fees paid by the related Mortgagor on Specially Serviced Loans,


 






     -218-


     


    

 


(iv)          100%
of assumption fees and other similar fees received with respect to Specially Serviced Loans, and


 


(v)          50%
of all Excess Modification Fees and assumption, waiver, consent and earnout and other similar fees (other than assumption application
fees and defeasance fees) pursuant to Section 3.08 or Section 3.18 received with respect to any Mortgage Loans (other
than Non-Serviced Mortgage Loans, but including any related Serviced Pari Passu Companion Loan(s)) that are Non-Specially Serviced
Loans to the extent that the matter involves a Major Decision or a Special Servicer Decision,


 


and
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 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 or on behalf of the related Mortgagor. The applicable 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 applicable 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 received by the Special Servicer;
provided, further, however, that 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) being equal to $25,000.
The Workout Fee shall be reduced (but not below zero) with respect to each collection on such Corrected Loan from which fee would
otherwise be payable until an amount equal to the 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


 






     -219-


     


    

 


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 was terminated become a Corrected Loan solely because the Mortgagor had not had sufficient time to make three
(3) consecutive timely Periodic Payments and which subsequently becomes a Corrected Loan as a result of the Mortgagor making such
three (3) consecutive timely Periodic Payments. The successor special servicer will not be entitled to any portion of such Workout
Fees. The Special Servicer will not be entitled to receive any Workout Fees after termination for cause. A Liquidation Fee will
be payable with respect to (a) 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 and (b) each Mortgage Loan repurchased by a Mortgage Loan Seller or for which a Loss of Value Payment was paid,
in each case, 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. 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 reduced or elected not to charge its respective portion of such fee will 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 will not be entitled to any of such fee charged


 






     -220-


     


    

 


by the Special Servicer. Similarly, if the Special Servicer decides not to charge any fee, the Master Servicer shall nevertheless
be entitled to charge its portion of the related fee to which the Master Servicer would have been entitled if the Special Servicer
had charged a fee and the Special Servicer shall not be entitled to any portion of such fee charged by the Master 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) (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. Notwithstanding the
foregoing or anything else herein to the contrary, 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
the Servicing Shift Whole Loan becomes a Specially Serviced Loan prior to the 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 the Special Servicer of such Serviced Whole Loan. With respect to the Servicing Shift Mortgage Loan, prior
to the related Servicing Shift Securitization Date, no other special servicer will be entitled to any such compensation or have
such rights and obligations. If the Servicing Shift Whole Loan is still a


 






     -221-


     


    

 


Specially Serviced Loan on the 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.


 


(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 related Remittance Date, an electronic report (which may include HTML, Word
or Excel compatible format, clean and searchable PDF format or such other format as mutually agreeable between the Certificate
Administrator and the Special Servicer) 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 or Serviced Companion 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 II hereto or such other payment instructions as CREFC® may provide to the Master Servicer
in writing at least two (2) Business Days prior to the Remittance Date) the CREFC® Intellectual Property Royalty
License Fee on a monthly basis. The Master Servicer shall withdraw from the Collection Account and, to the extent sufficient funds
are on deposit therein, pay the CREFC® Intellectual Property Royalty License Fee to CREFC® in accordance
with Section 3.05(a)(xii) on a monthly basis, from funds on deposit in the Collection Account.


 


Section
3.12     Inspections; Collection of Financial Statements. (a)  The Master Servicer 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

or more at least once every twelve (12) months and (ii) less than $2,000,000 at least once every twenty-four (24) months,
in each case, commencing in the calendar year 2018 (and each Mortgaged Property shall be inspected on or prior to December 31,
2019); provided, however, that if a physical inspection has been performed by the Special Servicer in the previous
twelve (12) months, the Master Servicer will not be required to perform, or cause to be

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 second proviso of the immediately preceding sentence shall be an expense of the Trust, and, to the extent not paid by the
related Mortgagor, reimbursed first from Penalty Charges actually received from the related Mortgagor and then from the
Collection Account 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) with respect to a Serviced Pari Passu Whole
Loan, pro rata and pari passu, from the related Serviced Pari Passu Mortgage Loan and Serviced Pari Passu Companion

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 AB Mortgage Loan, any
Serviced Pari Passu Companion Loans and the AB Subordinate Companion Loans), in each case, prior to being payable out of general
collections. The Special Servicer or the Master Servicer, as applicable, shall prepare or cause to be prepared a written report
of each such inspection detailing the condition of and any damage to the Mortgaged Property to the extent evident from the inspection
and specifying the existence of (i) any vacancy at the Mortgaged Property that the preparer of such report has knowledge
of and the Master Servicer or the Special Servicer, as the case may be, deems material, (ii) any sale, transfer or abandonment
of the Mortgaged Property of which the preparer of such report has knowledge or that is evident from the inspection, (iii) any
adverse change in the condition of the Mortgaged Property of which the preparer of such report has knowledge or that is evident

material waste committed on the Mortgaged Property of which the preparer of such report has knowledge or that is evident from
the inspection and (v) photographs of each inspected Mortgaged Property. The Special Servicer and the Master Servicer shall
promptly following preparation deliver or make available a copy (in electronic format) of each such report prepared by the Special
Servicer and the Master Servicer, respectively, to the other party, to the Directing Certificateholder ((i) prior to the

notice) (except, after the occurrence and continuance of a Consultation Termination Event or with respect to any Specially Serviced
Loan that is an Excluded Loan).

(b)          The

and any other reports or documents required to be delivered under the terms of the Mortgage Loans (and each Serviced Companion

Not
later than 5:00 p.m. (New York City time) on each P&I Advance Date beginning November 2017, the Master Servicer shall
deliver to the Certificate Administrator the CREFC® Schedule AL File in EDGAR-Compatible Format and Excel

CREFC® Schedule AL File unless the Depositor has delivered the items required by Section 2.01(j). If
the CREFC® Schedule AL File is not provided by the date specified in the immediately preceding sentence, the
Certificate Administrator shall request such CREFC® Schedule AL File from the Master Servicer via email at
ssreports@wellsfargo.com with a copy to the Depositor at nicholas.galeone@ubs.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, Initial Schedule AL Additional File and the 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


 






     -226-


     


    

 


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 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(d). 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(d). In the case of information or reports to be furnished by the Master
Servicer to the Certificate Administrator pursuant to Section 3.12(d), 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 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(d) 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 or make available
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) making such statement,
report or information available on the Master Servicer’s website (with respect to items delivered by the Master Servicer
(except with respect to items delivered by the Master Servicer to the Certificate Administrator)) or the Certificate Administrator’s
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)  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 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 Certificateholder 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 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


 






     -228-


     


    

 


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 otherwise materially harm 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.


 


Notwithstanding
the limitation set forth in the next succeeding paragraph, upon the reasonable request of any Certificateholder (or with respect
to any AB Subordinate Companion Loan related to a Serviced AB Whole Loan, the holder of such AB Subordinate Companion Loan) that
has delivered an Investor Certification to the Master Servicer or the Special Servicer, as the case may be, 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 make available electronically) or make available at the expense of such Certificateholder or holder of such AB
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 or Serviced AB Whole Loan, if requested by the holder of an
AB Subordinate Companion Loan, as the case may be) 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.


 


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 (except, with respect to a Mortgage Loan Seller, to the extent necessary for such party to comply
with its obligations under the related Mortgage Loan Purchase Agreement, and except for the Master Servicer and the Certificate
Administrator, acting in such capacities) or

Certificateholder or a Controlling
Class Certificateholder, if any such Person becomes an Excluded Controlling Class Holder, upon delivery to the Master Servicer,
the Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee in physical form (or, solely with respect
to the Master Servicer, in electronic form) of an investor certification substantially in the form of Exhibit P-1D
and upon delivery to the Certificate Administrator in physical form of an investor certification substantially in the form of
Exhibit P-1F, which shall include each of the CTSLink User ID associated with such Excluded Controlling Class Holder,
all information (other than the Excluded Information with respect to any Excluded Controlling Class Loans (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)) available on the Certificate Administrator’s Website.


 


In
the case of the Directing Certificateholder 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, the Directing
Certificateholder 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 Certificateholder
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 Certificateholder 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 Certificateholder 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) 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-1D 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) (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)) 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 at a later time, 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 Certificateholder 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 the case may be, has received a notice substantially in the
form of Exhibit P-1E from the Directing Certificateholder 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 Certificateholder 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 Administrator’s
Website) if the Master Servicer, the Special Servicer, the Operating Advisor or the Certificate Administrator, as the case may
be, 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 3.33.


 


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 Certificateholder 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 Certificateholder 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, the Directing
Certificateholder 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 the Directing Certificateholder or Controlling Class Certificateholder or
any of its Affiliates 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.


 


To
the extent the Risk Retention Consultation Party or a Holder of an RR Interest 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 Section 3.26(e), 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


 






     -235-


     


    

 


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 an RR Interest 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 an RR Interest 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 to any such Excluded Loan) shall be considered information that is aggregated with information of
other Mortgage Loans at a pool level.

information made available on its Internet website or its filing of such information pursuant to this Agreement, including, but
not limited to, filing via EDGAR, and assumes no responsibility 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 any Asset Status Report or Final Asset Status
Report inadvertently 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.

connection with providing access to the Certificate Administrator’s Website (other than with respect to access provided

Information
Provider and has been uploaded on to the 17g-5 Information Provider’s Website or (z) the Rating Agency confirms that
it does not intend to use such information in undertaking credit rating surveillance with respect to the Certificates; provided,
however, that the Rating Agencies may use information delivered under this clause (z) for any purpose to the
extent it is publicly available (unless the availability results from a breach of this Agreement) or comprised of information
collected by the applicable Rating Agency from the 17g-5 Information Provider’s Website (or another 17g-5 information provider’s
website that they have access to) other than pursuant to this Section 3.13(i).


 


(j)          The
costs and expenses of compliance with this Section 3.13 by the Depositor, the Master Servicer, the Special Servicer, the
Certificate Administrator, the Trustee, the Operating Advisor, the Asset Representations Reviewer and any other party hereto shall
not be additional expenses of the Trust, but shall be borne by the applicable party hereto.


 


Section
3.14     Title to REO Property; REO Account. (a)  If title to any Mortgaged Property is acquired (directly
or through a single member limited liability company established for that purpose) and thus becomes REO Property, the deed or
certificate of sale shall be issued in the name of the Trust where permitted by applicable law or regulation and consistent with
customary servicing procedures, and otherwise, in the name of the Trustee or its nominee on behalf of the Certificateholders and,
if applicable, on behalf of the related Companion Holders, in the case of a Serviced Companion Loan. REO Property with respect
to a Non-Serviced Mortgage Loan is excluded for all purposes of this Section 3.14. The Special Servicer, on behalf of the
Trust and, if applicable, the related Serviced Companion Noteholder, shall sell any REO Property prior to the close of the third
calendar year following the year in which the Trust acquires ownership of such REO Property, within the meaning of Treasury Regulations
Section 1.856-6(b)(1), for purposes of Section 860G(a)(8) of the Code, unless the Special Servicer either (i) applies
for a qualifying extension of time no later than sixty (60) days prior to the close of the third calendar year in which it acquired
ownership (or the period provided in the then-applicable REMIC Provisions) and such extension is granted or is not denied (an
“REO Extension”) by the Internal Revenue Service to sell such REO Property or (ii) obtains for the Trustee
and the Certificate 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. 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)          With
respect to (i) any Mortgage Loan other than the Fairmount at Brewerytown Mortgage Loan, the Special Servicer and (ii) the Fairmount
at Brewerytown Mortgage Loan, the Fairmount at Brewerytown Special Servicer, shall segregate and hold all funds collected and
received in connection with any REO Property separate and apart from its


 






     -242-


     


    

 


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 two (2) Business Days 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.


 


(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, 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 most recently ended Collection
Period, 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 the day the Special Servicer remits funds as provided in this Section 3.14, 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 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).


 


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 and the Trustee (as holder of the Lower-Tier 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


 






     -243-


     


    

 


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) 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 two (2) Business Days following receipt of such properly identified funds) in the
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 Certificateholder (other than with
respect to an Excluded Loan as to such party, 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:


 






     -244-


     


    

 


(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;


 


(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 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.


 


(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.


 






     -245-


     


    

 


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 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 including, without limitation, the period and amount of the occupancy level and physical condition of the related
Mortgaged Property and the state of the local economy; 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 or 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 (with respect to a
Specially Serviced Loan) or the Master Servicer (with respect to a Non-Specially Serviced Loan) shall promptly notify in writing
the other, 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 shall use reasonable
efforts to solicit offers for each Defaulted Loan on behalf of the Certificateholders and the holder of any related


 






     -246-


     


    

 


Serviced Companion
Loan in such manner as will be reasonably likely to maximize the value of the Defaulted Loan on a net present value basis, if
and when the Special Servicer determines, consistent with the Servicing Standard, that no satisfactory arrangements (including
by way of a discounted pay-off) can be made for collection of delinquent payments thereon and such a sale would be in the best
economic interests of the Trust and, if applicable, the related Companion Holder. In the case of a Non-Serviced Mortgage Loan,
to the extent permitted under the related Intercreditor Agreement, and such Non-Serviced Mortgage Loan is not sold together with
the Non-Serviced Companion Loan by the Non-Serviced Special Servicer, the Special Servicer will be entitled to sell ((i) with
the consent of the Directing Certificateholder if no Control Termination Event has occurred and is continuing and (ii) after consulting
with the Risk Retention Consultation Party pursuant to Section 6.08(a), in each case, provided 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 (and provided that the related Non-Serviced Special Servicer will not be entitled to a liquidation fee), the Special
Servicer will 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 and the Directing Certificateholder and the Risk Retention Consultation
Party (in the case of the Directing Certificateholder 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 the absence of a cash offer at least equal to the Purchase Price, the Special Servicer may purchase the Defaulted Loan
for the Purchase Price or may accept the first cash offer received from any Person that constitutes a fair price for the Defaulted
Loan.


 


(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 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 sub-clause (B) below, 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 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, 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 nine (9) 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 (provided that the Trustee may not be an offeror),
the Trustee shall determine whether the offer constitutes a fair price unless such offer by an Interested Person (i) is equal
to or greater than the applicable Purchase Price and (ii) is the highest offer received. Absent an offer at least equal to
the Purchase Price, no offer from an Interested Person shall constitute a fair price unless (x) it is the highest offer received
and (y) at least two (2) other offers are received from independent third parties.


 






     -247-


     


    

 


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 nine (9) 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 by the Master Servicer.


 


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, the Trustee shall (at the expense of the Interested Person) designate an independent
third party expert in real estate or commercial mortgage loan matters with at least five (5) years’ experience in valuing
loans similar to the subject Mortgage Loan or Serviced Whole 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 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 by, the Interested Person; provided that the Trustee
will not engage a third party expert whose fees exceed a commercially reasonable amount as determined by the Trustee. 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. 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 will not be obligated to accept the highest offer if the Special Servicer determines (in consultation with the
Directing Certificateholder and the Risk Retention Consultation Party, subject to the limitations on consultation set forth in
and in accordance with 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 or an REO Property related
to a Serviced Whole Loan, the related Companion Holder (as a collective whole, as if such Certificateholders and, if applicable,
the related Companion Holder constituted a single lender). In addition, the Special Servicer may accept a lower offer from any
Person other than an Affiliate of the Special Servicer if it determines, in accordance with the


 






     -248-


     


    

 


Servicing Standard, that the acceptance
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
or an REO Property related to a Serviced Whole Loan, the related Companion Holder (as a collective whole, as if such Certificateholders
and, if applicable, the related Companion Holder constituted a single lender) (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)  The
Special Servicer may purchase any REO Property at the 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 Certificateholder and the Risk Retention Consultation Party (in the case of the Directing Certificateholder
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 (x) purchase any REO Property at the Purchase Price therefor or (y) 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 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.


 


(A)          In
the absence of any such offer as set forth in clause (i) above, the Special Servicer shall, subject to sub-clause (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


 






     -249-


     


    

 


Interested Person, or (2) by the Trustee, if the highest
offeror is an Interested Person unless such offer by an Interested Person (i) is equal to or greater than the applicable
Purchase Price and (ii) is the highest offer received; provided, however, that absent an offer at least equal
to the Purchase Price, no offer from an Interested Person shall constitute a fair price unless (A) it is the highest offer
received and (B) at least two (2) 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.


 


(B)          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, 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, 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.


 


(C)          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 and 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 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


 






     -250-


     


    

 


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 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 a Serviced Whole Loan, such determination shall be made by the Trustee if the offeror
is an Interested Person. Notwithstanding the foregoing, the Special Servicer will 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 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 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; 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


 






     -251-


     


    

 


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 shall (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
five (5) years’ experience in valuing 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, pursuant to the terms of the related Intercreditor Agreement, the holder
of the related AB Subordinate Companion Loan for each applicable Serviced AB Whole 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 will no longer be subject to this Agreement.


 


(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) 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.


 


(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.


 


(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 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, 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 Certificateholder or 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 Certificateholder), 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 Collection Period for any Distribution
Date, the Master Servicer or the Trustee shall further be authorized to wait for principal collections on the Mortgage 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 Collection Period will exceed the full amount of the principal portion
of general collections on or in respect of 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


 






     -253-


     


    

 


Website pursuant to Section
3.13(c), unless extraordinary circumstances make such notice impractical, which shall mean that (i) the Master Servicer
or the Trustee, as the case may be, determines in its sole discretion that waiting fifteen (15) days after such a notice could
jeopardize its ability to recover such Nonrecoverable Advance, (ii) changed circumstances or new or different information
becomes known to the Master Servicer or the Trustee, as the case may be, that could affect or cause a determination of whether
any Advance is a Nonrecoverable Advance or whether to defer reimbursement of a Nonrecoverable Advance or the determination in
clause (i) above, or (iii) in the case of the Master Servicer, it has not timely received from the Trustee information
required by the Master Servicer to determine whether to defer reimbursement for a Nonrecoverable Advance. If any of the circumstances
described in clause (i), (ii) or (iii) of the foregoing sentence apply, the Master Servicer or Trustee,
as applicable, shall give the 17g-5 Information Provider a notice for posting of the anticipated reimbursement as soon as reasonably
practicable. Notwithstanding the foregoing, failure to give notice as required by the preceding or second preceding sentence shall
in no way affect the Master Servicer’s or the Trustee’s election whether to refrain from obtaining such reimbursement
or right to obtain 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 Master Servicer or the Trustee, as the case may be, shall
have no liability for any loss, liability or expenses resulting from any notice provided to the Rating Agencies contemplated by
this Section 3.17(c).


 


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 this Section 3.17 or to comply with the terms
of this 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 the case may be, determines, in its sole discretion, to fully recover the
Nonrecoverable Advances immediately instead of deferring such reimbursement, then the Master Servicer or the Trustee, as 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 from 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 the case may be, 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


 






     -254-


     


    

 


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 this Section 3.17 or for any losses, damages or other adverse economic or other effects that may arise
from such an election, nor shall such election constitute a violation of the Servicing Standard or any duty under this Agreement.
Neither the Master Servicer nor the Trustee shall have any liability whatsoever for making an election, or refraining from making
an election, that is authorized under this Section 3.17(c).


 


No
determination by the Master Servicer (or the Trustee, as applicable) to exercise its sole option to defer the reimbursement of
Advances and/or interest thereon under this section shall be construed as an agreement by the Master Servicer (or the Trustee,
as applicable) to subordinate (in respect of realizing losses), to any Class of Certificates, such party’s right to such
reimbursement during such period of deferral.


 


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).


 


(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)          Within
one (1) Business Day after the execution of any amendment or modification of any Intercreditor Agreement, the Master Servicer
or the Special Servicer, as the case may be, shall provide to the Certificate Administrator a copy of any such modification or
amendment of any Intercreditor Agreement, and such amendment or modification shall be a Reportable Event.


 


Section
3.18     Modifications, Waivers, Amendments and Consents. (a)  The Special Servicer
shall process waivers, modifications, amendments and consents with respect to Specially Serviced Loans and all such matters that
involve a Major Decision or Special Servicer Decision for all Mortgage Loans (and any related Serviced Companion Loan) that are
not Specially Serviced Loans, and the Master Servicer shall process waivers, modifications, amendments and consents with respect
to any Mortgage Loan (other than any Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that is not a Specially
Serviced Loan


 






     -255-


     


    

 


and does not involve a Major Decision or a Special Servicer Decision. 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), Section
3.18(m) and Section 6.08, but subject to any other conditions set forth thereunder 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, as applicable, to advise or consult with the Special Servicer 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 Special Servicer shall not modify, waive or amend the terms of a Mortgage Loan and/or related Companion Loan that would constitute
a Major Decision without (x) (i) prior to the occurrence of a Control Termination Event and (ii) other than with
respect to any Excluded Loan with respect to the Directing Certificateholder, the consent (or deemed consent) of the Directing
Certificateholder having been obtained by the Special Servicer to the extent required by, and pursuant to the process described
under, Section 6.08(a) or (y) (i) after the occurrence and during the continuance of a Control Termination Event
and (ii) other than with respect to any Excluded Loan with respect to the Directing Certificateholder, but prior to the occurrence
and continuance of a Consultation Termination Event, the Special Servicer having consulted with the Directing Certificateholder
if and to the extent required pursuant to Section 6.08(a); and provided, further, 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 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 Special Servicer shall provide the Trustee, the Certificate Administrator, the Master Servicer, the Operating Advisor,
the Directing Certificateholder and the Risk Retention Consultation Party (in the case of the Directing Certificateholder 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, (x) 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,
the Special Servicer shall obtain the consent (or deemed consent) of the Directing Certificateholder, (y) after the occurrence
and during the continuance of a Control Termination Event, but prior to the occurrence and continuance of a Consultation Termination
Event, and other than with respect to any Excluded Loan with respect to the Directing Certificateholder, consult with the Directing
Certificateholder and (z) (i) prior to the occurrence and continuance of a Consultation Termination Event, with respect to any
Specially Serviced Loan other than an Excluded Loan with respect to the Risk Retention


 






     -256-


     


    

 


Consultation Party and (ii) after the occurrence
and during the continuance of a Consultation Termination Event, with respect to any Mortgage Loan other than an Excluded Loan
with respect to the Risk Retention Consultation Party, consult with the Risk Retention Consultation Party, in each case, pursuant
to the process described in Section 6.08(a).


 


Additionally,
the Special Servicer shall not modify, waive or amend the terms of any Mortgage Loan and/or related Companion Loan that would
constitute a Special Servicer Decision under any of clauses (d), (e), (f) and (g) of the definition of “Special
Servicer Decision” unless (x) (i) prior to the occurrence of a Control Termination Event and (ii) other than
with respect to any Excluded Loan with respect to the Directing Certificateholder, the Directing Certificateholder has consented
in writing within ten (10) Business Days (or, with respect to clause (g) of the definition of “Special Servicer
Decision”, five (5) business days) after the Directing Certificateholder’s receipt of the Special Servicer’s
written recommendation and analysis and all information reasonably requested by the Directing Certificateholder, and reasonably
available to the Special Servicer in order to grant or withhold such consent (provided that if such written consent has
not been received by the Special Servicer within such ten (10) Business Day (or five (5) Business Day, as applicable) period,
then the Directing Certificateholder will be deemed to have approved such action) or (y) (i) after the occurrence and
during the continuance of a Control Termination Event and (ii) other than with respect to any Excluded Loan with respect
to the Directing Certificateholder, but prior to the occurrence and continuance of a Consultation Termination Event, the Special
Servicer having consulted with the Directing Certificateholder. In the event the Special Servicer receives no response from the
Directing Certificateholder within ten (10) Business Days (or, with respect to clause (g) of the definition of “Special
Servicer Decision”, five (5) business days) following its written request for input on any required consultation, the Special
Servicer shall not be obligated to consult with the Directing Certificateholder, as applicable, on the specific matter; provided,
however, that the failure of the Directing Certificateholder to respond shall not relieve the Special Servicer from
consulting with the Directing Certificateholder on any future matters with respect to the applicable Mortgage Loan (other than
a Non-Serviced Mortgage Loan or an Excluded Loan with respect to the Directing Certificateholder) or Serviced Whole Loan.


 


Notwithstanding
the foregoing, subject to the rights of the related Companion Holder to advise the Master Servicer with respect to, or consent
to, such modification, waiver or amendment pursuant to the terms of the related Intercreditor Agreement, the Master Servicer,
with respect to Non-Specially Serviced Loans, without the consent of the Special Servicer or the Directing Certificateholder,
may modify or amend the terms of any Non-Specially Serviced Loan and/or related Serviced Companion Loan in order to (i) cure
any ambiguity or mistake therein or (ii) correct or supplement any provisions therein which may be inconsistent with any
other provisions therein or correct any error; 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


 






     -257-


     


    

 


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 Certificateholder 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).


 


Upon
receiving a request for any matter described in this Section 3.18(a) that constitutes a Special Servicer Decision or Major
Decision with respect to a Mortgage Loan that is a Non-Specially Serviced Loan, the Master Servicer shall promptly forward such
request to the Special Servicer and the Special Servicer shall process such request (including, without limitation, interfacing
with the Mortgagor) and except as provided in the next sentence, the Master Servicer shall have no further obligation with respect
to such request or the Major Decision or Special Servicer Decision. The Master Servicer will deliver to the Special Servicer any
additional information in the Master Servicer’s possession requested by the Special Servicer relating to such Major Decision.
The Master Servicer shall not be permitted to process any such Major Decision or Special Servicer Decision and shall not be required
to interface with the Mortgagor or provide a written recommendation and/or analysis with respect to any such Major Decision or
Special Servicer Decision.


 


(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 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 (w) the
provisions of this Section 3.18(b) and Section 3.18(c), (x) with respect to any such Specially Serviced Loan other
than an Excluded Loan with respect to the Directing Certificateholder, prior to the occurrence and continuance of a Control Termination
Event, the approval of the Directing Certificateholder (or after the occurrence and


 






     -258-


     


    

 


during the continuance of a Control Termination
Event, but prior to the occurrence and continuance of a Consultation Termination Event, upon consultation with the Directing Certificateholder)
as provided in Section 6.08, (y) with respect to any such Specially Serviced Loan other than an Excluded Loan with respect
to the Risk Retention Consultation Party, upon consultation with the Risk Retention Consultation Party as provided in Section
6.08, 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 or mezzanine intercreditor agreement, as
applicable; provided that with respect to any Serviced AB Whole Loan, prior to the occurrence and continuance of a related
AB Control Appraisal Period, the related Serviced AB Whole Loan Controlling Holder will be required to the extent set forth in
the related Intercreditor Agreement and the Directing Certificateholder shall have no consent or consultation rights, and the
Risk Retention Consultation Party shall have no consultation rights, regarding the matter; provided, further, that
in the case of any release or substitution of collateral (other than a defeasance), the Special Servicer shall have obtained and
provided to the Trustee and the Certificate Administrator 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 Certificateholder (regardless of whether a Control Termination 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 (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 the case may be, 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.


 


If,
following any such release or taking, the loan-to-value ratio as calculated is greater than 125%, the Master Servicer or the Special
Servicer, as the case may be, 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” within the meaning of Section 860G(a)(3)
of the Code.


 






     -259-


     


    

 


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 (5) years prior to the Rated Final Distribution Date and (b) if
such 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, to the extent consistent with the Servicing Standard giving due consideration to the remaining
term of the ground lease and (A) prior to the occurrence and continuance of a Control Termination Event, with the consent of the
Directing Certificateholder and (B) to the extent such modification, waiver or amendment constitutes a Major Decision, after consultation
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), 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, or Serviced Whole Loan 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 the Master Servicer or the 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, the first sentence of Section 3.18(a), and Section
6.08), the Master Servicer (as provided in Section 3.08(a), Section 3.08(b) and Section 3.18 if such
matter constitutes a Master Servicer Decision) or the Special Servicer (as provided in Section 3.08(a), Section 3.08(b)
and Section 3.18(a) if any such waiver, modification or amendment constitutes a Major Decision or a Special Servicer
Decision or relates to a Specially Serviced Loan) 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. In making this determination, the Master Servicer or the 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 extent permitted under the related Mortgage Loan documents). Notwithstanding the foregoing, neither the Master Servicer
nor the Special Servicer


 



     -260-


     


    

 


may waive the payment of any Prepayment Premium or Yield Maintenance Charge or the requirement that any
prepayment of a Mortgage 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 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, 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 for which it is responsible for processing pursuant to Section 3.18, the
Special Servicer shall notify the Master Servicer, the Trustee, the Certificate Administrator, the Operating Advisor (after the
occurrence and during the continuance of a Control Termination Event), the Directing Certificateholder and the Risk Retention
Consultation Party (in the case of the Directing Certificateholder, other than following the occurrence and continuance of a Consultation

thereof. With respect to any modification, waiver or amendment (in each case, after it is finalized and executed) for which it
is responsible for processing pursuant to Section 3.18, 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 Certificateholder and the Risk Retention Consultation Party (in the case of the Directing Certificateholder,

of such Mortgage Loan or the Directing Certificateholder 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 R or Class

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 JJ, to cts.sec.notifications@wellsfargo.com and an Additional Disclosure Notification in the form attached
hereto as Exhibit DD. The notice contemplated in the preceding sentence shall set forth, to the extent the Special
Servicer or the 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 the 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 JJ shall no longer be required hereunder. From time
to time, the Master Servicer, the Special Servicer and the 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


 



     -262-


     


    

 


shall be entitled to all defeasance fees paid relating thereto (provided that for
the avoidance of doubt, any such defeasance fee shall not include 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 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 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 (10) 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.

(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 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 or 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).

party or has retained on behalf of itself or an Affiliate the right to establish or designate the successor borrower and/or to
purchase or cause to be purchased the related defeasance collateral (any such right or obligation, the “Retained Defeasance
Rights and Obligations”). In the event the Master Servicer receives notice of a defeasance request with respect to a
Mortgage Loan for which UBS AG, by and through its branch office at 1285 Avenue of the Americas, New York, New York, Société


 



     -264-


     


    

 


Générale, Ladder Capital Finance LLC, Rialto Mortgage Finance, LLC, CIBC Inc. or Natixis Real Estate Capital LLC,
as applicable, is the related Mortgage Loan Seller, which such Mortgage Loan provides for Retained 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 UBS AG, by and through its branch office at 1285 Avenue of the Americas, New York,
New York, Société Générale, Ladder Capital Finance LLC, Rialto Mortgage Finance, LLC, CIBC Inc. or
Natixis Real Estate Capital LLC, as applicable, in the case of any such Mortgage Loan for which UBS AG, by and through its branch
office at 1285 Avenue of the Americas, New York, New York, Société Générale, Ladder Capital Finance
LLC, Rialto Mortgage Finance, LLC, CIBC Inc. or Natixis Real Estate Capital LLC, as applicable, is the related Mortgage Loan Seller.
Until such time as UBS AG, by and through its branch office at 1285 Avenue of the Americas, New York, New York, Société
Générale, Ladder Capital Finance LLC, Rialto Mortgage Finance, LLC, CIBC Inc. or Natixis Real Estate Capital LLC,
as applicable, provides the Master Servicer with written notice to the contrary, the notice of a defeasance of a Mortgage Loan
with Retained Defeasance Rights and Obligations as to which UBS AG, by and through its branch office at 1285 Avenue of the Americas,
New York, New York, Société Générale, Ladder Capital Finance LLC, Rialto Mortgage Finance, LLC, CIBC
Inc. or Natixis Real Estate Capital LLC is the related Mortgage Loan Seller shall be delivered to the related Mortgage Loan Seller
at its respective notice address provided under Section 13.05. With respect to any Mortgage Loan originated or acquired
by UBS AG, by and through its branch office at 1285 Avenue of the Americas, New York, New York, Société Générale,
Ladder Capital Finance LLC, Rialto Mortgage Finance, LLC, CIBC Inc. or Natixis Real Estate Capital LLC, as applicable, that is
subject to defeasance, if the successor borrower is not designated or formed by UBS AG, by and through its branch office at 1285
Avenue of the Americas, New York, New York, Société Générale, Ladder Capital Finance LLC, Rialto Mortgage
Finance, LLC, CIBC Inc. or Natixis Real Estate Capital LLC, 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 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 “Available Funds”
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


 



     -265-


     


    

 


maintained in the Collection Account for a period in excess of three
hundred sixty-five (365) days (or three hundred sixty-six (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 the case may be, 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 (10) largest Mortgage Loans a by Stated Principal Balance or (ii) has an unpaid principal
balance that is at least equal to 5% of the then-aggregate principal balance of all Mortgage Loans or $35,000,000.


 


(l)       Notwithstanding
anything to the contrary in this Agreement, in connection with any modification, waiver, consent or amendment in connection with
any release of collateral securing any Mortgage Loan in connection with a defeasance of such collateral, the Special Servicer
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 Special Servicer and the Master Servicer that such modification, waiver, consent or amendment will
not cause an Adverse REMIC Event to the extent the Special Servicer determines in its reasonable good faith business judgment
consistent with the Servicing Standard that such Opinion of Counsel is reasonably necessary.


 


(m)       Notwithstanding
any other provisions of this Section 3.18 or Section 3.08, but subject to any related Intercreditor Agreement, the
Master Servicer may, without any Directing Certificateholder approval, consent or consultation (except as otherwise provided below
in the definition of Master Servicer Decision), Risk Retention Consultation Party consultation or the Special Servicer’s
approval, consent or consultation (provided that the Master Servicer delivers notice thereof to the Special Servicer after
completion (and the Special Servicer shall promptly, prior to the occurrence of a Consultation Termination Event and other than
in respect of any Excluded Loan with respect to the Directing Certificateholder, deliver notice thereof to the Directing Certificateholder,
except to the extent that the Special Servicer notifies the Master Servicer that the Special Servicer does not desire to receive
copies of such items) take any of the following actions with respect to Non-Specially Serviced Loans (each such action, a “Master
Servicer Decision”): (i) grant waivers of non-material covenant defaults (other than financial covenants and receipt
of financial statements, but including immaterial timing waivers such as with respect to late financial statements); (ii) consents
to releases of non-material, non-income producing parcels of a Mortgaged Property that do not materially affect the use or value
of the related Mortgaged Property or the ability of the related Mortgagor to pay amounts due in respect of the Mortgage Loan as
and when due, provided such releases are required by the related Mortgage Loan documents and there is no lender discretion permitted
under the Mortgage Loan documents; (iii) approve or consent to grants of easements or rights of way


 



     -266-


     


    

 


(including, without limitation
for utilities, access, parking, public improvements or another purpose) or subordination of the lien of the Mortgage Loan to easements
if the Special Servicer has determined, in accordance with the proviso to the definition of “Special Servicer Decision”,
that such easements or rights of way do not materially affect the use or value of a Mortgaged Property or a Mortgagor’s
ability to make payments with respect to the related Mortgage Loan or any related Companion Loan; (iv) grant subordination,
non-disturbance and attornment agreements and consents involving leasing activities that do not involve a ground lease and affect
an area less than or equal to the lesser of (a) 30% of the net rentable area of the improvements at the Mortgaged Property
and (b) 30,000 square feet of the improvements at the Mortgaged Property), including approval of new leases and amendments
to current leases; (v) consent to actions and releases related to condemnation of parcels of a Mortgaged Property if the
Special Servicer has determined, in accordance with the proviso to the definition of “Special Servicer Decision”,
that such condemnation is not with respect to a material parcel or a material income producing parcel and such condemnation does
not materially affect the use or value of the related Mortgaged Property or the ability of the related Mortgagor to pay amounts
due in respect of the related Mortgage Loan or Companion Loan when due; (vi) consent to a change in property management relating
to any Mortgage Loan if the replacement property manager is not a Borrower Party and the Mortgage Loan has an outstanding principal
balance less than $10,000,000; (vii) approve annual operating budgets for Mortgage Loans; (viii) grant any extension or enter
into any forbearance with respect to the anticipated refinancing of a Mortgage Loan or sale of a Mortgaged Property after the
related Maturity Date of such Mortgage Loan so long as (A) such extension or forbearance does not extend beyond 120 days
after the related Maturity Date and (B) the related Mortgagor has delivered documentation reasonably satisfactory in form
and substance to the Master Servicer or the Special Servicer which provides that a refinancing of such Mortgage Loan or sale of
the related Mortgaged Property will occur within 120 days after the date on which such Balloon Payment will become due; (ix) any
non-material modification, amendment, consent to a non-material modification or waiver of any term of any Intercreditor Agreement
if the Special Servicer has determined, in accordance with the proviso to the definition of “Major Decision” that
such modification, amendment or consent is administrative in nature, including a note-splitting amendment, provided that
if any such modification or amendment would adversely impact the Special Servicer, such modification or amendment will additionally
require the consent of the Special Servicer, as applicable, as a condition to its effectiveness; (x) any determination of
Acceptable Insurance Default, except that, prior to the occurrence and continuance of any Control Termination Event and other
than in the case of any Excluded Loan with respect to the Directing Certificateholder, the Directing Certificateholder’s
consent (or deemed consent) shall be required for any such determination; (xi) approve or consent to any defeasance of the
related Mortgage Loan or Serviced Companion Loan other than agreeing to (A) a modification of the type of defeasance collateral
required under the Mortgage Loan or Serviced Whole Loan documents other than direct, non-callable obligations of the United States
would be permitted or (B) a modification that would permit a principal prepayment instead of defeasance if the Mortgage Loan
or Serviced Whole loan documents do not otherwise permit such principal prepayment; (xii) any determination to bring a Mortgaged
Property into compliance with applicable environmental laws or to otherwise address hazardous material located at a Mortgaged
Property subject, 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, to the consent (or deemed consent) of the


 



     -267-


     


    

 


Directing Certificateholder; (xiii) any
transfer of the Mortgaged Property that the loan documents allow without the consent of the mortgagee but subject to satisfaction
of conditions specified in the loan documents where no mortgagee discretion is necessary in order to determine if such conditions
are satisfied; (xiv) to the extent not a Major Decision or a Special Servicer Decision pursuant to clause (x) of the definition
of “Major Decision” or clause (c) of the definition of “Special Servicer Decision”, respectively,
any requests for the funding or disbursement of amounts from any escrow accounts, reserve funds or letters of credit held as “performance”,
“earn-out”, “holdback” or similar escrows or reserves where such request is for funding or disbursement
of ordinary course impounds, repair and replacement reserves, lender approved budget and operating expenses, and tenant improvements
pursuant to an approved lease, each in accordance with the Mortgage Loan documents (all such fundings and disbursements being
collectively referred to as “Routine Disbursements”) or any other funding or disbursement as mutually agreed
upon by the Master Servicer and the Special Servicer; provided, however, that in the case of any Mortgage Loan whose
escrows, reserves, holdbacks and related letters of credit exceed, in the aggregate, at the related origination date, 10% of the
initial principal balance of such Mortgage Loan (which Mortgage Loans are identified on Schedule 3 hereto), no such funding
or disbursement of such escrows, reserves, holdbacks or letters of credit shall be deemed to constitute a Routine Disbursement,
and shall instead constitute Special Servicer Decisions, except for the routine funding of tax payments and insurance premiums
when due and payable; and (xv) grant or agree to any other waiver, modification, amendment and/or consent that does not constitute
a Major Decision or a Special Servicer Decision; provided that (w) any such action would not in any way affect a payment
term of the Certificates, (x) any such action 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 cause either Trust REMIC
to fail to qualify as a REMIC for federal income tax purposes (as evidenced by an Opinion of Counsel (at the expense of the Trust
to the extent not reimbursed or paid by the related Mortgagor), to the extent requesting such opinion is consistent with the Servicing
Standard), (y) agreeing to such action would be consistent with the Servicing Standard, and (z) agreeing to such action
would not violate the terms, provisions or limitations of this Agreement or any Intercreditor Agreement; provided, further,
that, in the case of any Master Servicer Decision that requires the consent of the Directing Certificateholder, such consent shall
be deemed given if a response to the request for consent is not provided within 10 Business Days after receipt of the Master Servicer’s
written recommendation and analysis and all information reasonably requested by the Directing Certificateholder, and reasonably
available to the Master Servicer in order to grant or withhold such consent. The foregoing is intended to be an itemization of
actions the Master Servicer may take without having to obtain the approval of any other party and is not intended to limit the
responsibilities of the Master Servicer hereunder.


 


(n)       Neither
the Master Servicer nor the Special Servicer shall modify any Mortgage Loan into an AB Modified Loan unless the documents evidencing
such modification provide that all payments on the junior or “B” portion of such AB Modified Loan (including interest,
principal and other amounts) shall only be payable after the point in time at which all interest and principal on the senior or
“A” portion of such AB Modified Loan shall have been paid in full and such senior or “A” portion shall
no longer be outstanding; provided, however, that interest and other amounts in respect of such junior or “B” portion
may accrue prior to such point in time.

Section
3.19     Transfer of Servicing Between the Master Servicer and the 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 ((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) the Directing Certificateholder 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 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) or (ix)
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, and ((i) prior
to the occurrence and continuance of a Consultation Termination Event or (ii) other than with respect to any Excluded
Loan as to such party) the Directing Certificateholder, 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 (3)
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 an AB Subordinate Companion Loan an AB Control Appraisal Period has occurred) and
the Directing Certificateholder (with respect to the Directing Certificateholder, (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 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


 






     -269-


     


    

 


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.


 


(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
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 sixty (60) days after a Servicing Transfer Event for a Mortgage Loan (other than a Non-Serviced Mortgage Loan) and,
if applicable, the related Companion 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, if applicable, and the related Mortgaged
Property to the Master Servicer, the Directing Certificateholder (but with respect to the Directing Certificateholder, only in
respect of any Mortgage Loan other than (A) any Excluded Loan as to such party or (B) any Serviced AB Whole Loan prior to the
occurrence of an AB Control Appraisal Period, and in any event 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), the Operating Advisor (but, other than with respect to an Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class, only after the occurrence and during the continuance of a Control Termination
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 related Companion
Holder or, to the extent the related Serviced Companion Loan has been included in an Other Securitization, to the applicable master
servicer of such Other Securitization into which the related Serviced Companion Loan has been sold; the Special Servicer shall
also deliver a summary of each Final Asset Status Report to the Certificate Administrator and the Certificate Administrator shall
post the summary of the Final Asset Status Report to the Certificate Administrator’s Website. 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;


 






     -270-


     


    

 


(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 Mortgage Loan (and any related Serviced Companion Loan) and whether outside legal counsel has been
retained;


 


(iii)       the
most current rent roll, 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

(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


 


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


 


If
within ten (10) Business Days of receiving an Asset Status Report, the Directing Certificateholder 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 Certificateholder (communicated to the Special Servicer within ten (10) Business Days) is not in
the best interest of all the Certificateholders and the holder of any


 



     -271-


     


    

 


related Companion Loan, as a collective whole (taking into
account the pari passu or subordinate nature of any Companion Loan), 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 other than an Excluded Loan with respect to the Directing Certificateholder or the Holder of a majority of
the Controlling Class, prior to the occurrence and continuance of any Control Termination Event, the Directing Certificateholder
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
Certificateholder (prior to the occurrence and continuance of a Consultation Termination Event and, in the case of a Serviced
AB Whole Loan, only prior to the occurrence and continuance of a Consultation Termination Event and during an AB Control Appraisal
Period with respect to the related AB Subordinate Companion Loan), the Operating Advisor (but only after the occurrence and during
the continuance of a Control Termination 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)). With respect to any Mortgage Loan other
than an Excluded Loan with respect to the Directing Certificateholder 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 Certificateholder 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 and the holder of any related Companion Loan, as a collective whole (taking into account the pari passu
or subordinate nature of any Companion Loan); provided that, if the Directing Certificateholder 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
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
Certificateholder or the Holder of the majority of the Controlling Class (regardless of whether a Control Termination Event has
occurred and is continuing), the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in connection
with an Asset Status Report for an Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority
of the Controlling Class that includes a Major Decision 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.


 






     -272-


     


    

 


No
direction or disapproval of the Directing Certificateholder hereunder or under a related Intercreditor Agreement or failure of
the Directing Certificateholder 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, or (b) result
in the imposition of a “prohibited transaction” or “prohibited contribution” tax under the REMIC Provisions,
or (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, the Trustee’s or the
Master Servicer’s responsibilities under this Agreement.


 


If
a Control Termination Event has occurred and is continuing (or, with respect to a Serviced AB Whole Loan, if both a Control Termination
Event has occurred and is continuing and an AB Control Appraisal Period is in effect), the Special Servicer shall promptly deliver
each Asset Status Report prepared in connection with a Specially Serviced Loan to the Operating Advisor (and the Directing Certificateholder
(if no Consultation Termination Event has occurred and is continuing and such Specially Serviced Loan is not an Excluded Loan
as to such party)). The Operating Advisor shall provide comments to the Special Servicer in respect of the 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 Control Eligible Certificates), as a collective whole. The Special Servicer shall
consider such alternative courses of action and any other feedback provided by the Operating Advisor (and the Directing Certificateholder
(in each case, if no Consultation Termination Event has occurred and is continuing and such Specially Serviced Loan is not an
Excluded Loan as to such party or a Non-Serviced Mortgage Loan)) in connection with the Special Servicer’s preparation of
any Asset Status Report. 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 the Directing Certificateholder (if no Consultation Termination Event has
occurred and is continuing and such Specially Serviced Loan is not an Excluded Loan as to such party)), to the extent the Special
Servicer determines that the Operating Advisor’s and/or Directing Certificateholder’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, as
a collective whole (taking into account the pari passu or subordinate nature of such Companion Loan)).


 


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 Certificateholder or the Holder of the majority of the Controlling Class), the Directing Certificateholder
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
Directing


 



     -273-


     


    

 


Certificateholder (except with respect to any Excluded Loan as to such party) and the Operating Advisor 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 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 Certificateholder during the applicable periods described above, but is under no obligation to follow any particular
recommendation of the Operating Advisor or the Directing Certificateholder


 


After
the occurrence and during the continuance of a Control Termination Event (and at any time with respect to any Excluded Loan),
the Directing Certificateholder 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 Directing Certificateholder (except with respect to any Excluded Loan) and after the occurrence and during
the continuance of a Control Termination Event, the Operating Advisor, shall consult on a non-binding basis with the Special Servicer
and propose alternative courses of action and provide other feedback in respect of any Asset Status Report. 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)), 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 Certificateholder during the applicable periods described
above, but is under no obligation to follow any particular recommendation of the Operating Advisor or the Directing Certificateholder.


 


Notwithstanding
the foregoing, prior to the occurrence and continuance of an AB Control Appraisal Period with respect to an AB Subordinate Companion
Loan, the applicable Special Servicer shall prepare an Asset Status Report for any Serviced AB Whole Loan, upon it becoming a
Specially Serviced Loan pursuant to this Agreement and the related Intercreditor Agreement, but the Directing Certificateholder
will have no approval rights over any such Asset Status Report, and the consent or approval rights with respect to such Asset
Status Report shall be as set forth in the related Intercreditor Agreement.


 


(e)       (i)  Upon
receiving notice of the occurrence of the events described in clause (iv) or (ix) of the definition of Servicing
Transfer Event (without regard to the 60-day period 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


 



     -274-


     


    

 


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 (iv) or (ix) of the definition of Servicing Transfer Event (without regard to the 60-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, 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 Serviced AB Mortgage 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), to the Directing Certificateholder). With respect to any Mortgage 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 twentieth (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 and the holder of any related Companion Loan, as a collective whole
(taking into account the pari passu or subordinate nature of any Companion Loan), 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 of each Final Asset Status Report to the Operating Advisor. The Special Servicer shall prepare a summary
of any Final Asset Status Report related to any Serviced AB Whole Loan for which the related holder of an AB Subordinate Companion
Loan is not subject to an AB Control Appraisal Period, which Final


 



     -275-


     


    

 


Asset Status Report has been approved or deemed approved by
the holder of the related AB Subordinate Companion Loan in accordance with the related Intercreditor Agreement (to the extent
such Intercreditor 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 a recommendation of the Operating Advisor.


 


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 the case may be, 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 under the circumstances described
therein (subject to Section 3.20(g)); (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 Special Servicer,
as applicable, (other than the Master Servicer or Special Servicer that enters into such Sub-Servicing Agreement) any successor
master servicer or successor 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 pursuant to this Agreement to terminate such Sub-Servicing Agreement with respect to such purchased Mortgage 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) 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 except through the Master Servicer or the Special Servicer, as the case may be,
if and only to the extent provided pursuant to Section 6.04; (vi) does not permit the Sub-Servicer to modify any Mortgage
Loan unless and to the extent the Master Servicer or the Special Servicer, as the case may be, is permitted hereunder to modify
such Mortgage Loan; (vii) does not permit the Sub-Servicer to take any action constituting a Major Decision without the consent
of the Master 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


 



     -276-


     


    

 


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, the Certificate Administrator or the Depositor under ARTICLE XI or under
the Sub-Servicing Agreement or to the applicable 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 successor special servicer, as applicable,
hereunder shall, upon becoming a successor master servicer or successor special servicer, as applicable, be assigned and may assume
any Sub-Servicing Agreements from the applicable predecessor Master Servicer or Special Servicer, as the case may be (subject
to Section 3.20(g)). 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 serviced thereunder at the
time such Mortgage 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 Special Servicer, as the case may be, shall deliver to the Trustee copies of all Sub-Servicing
Agreements, and any amendments thereto and modifications thereof, entered into by it, in each case promptly upon its execution
and delivery of such documents. 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 Servicer, as the case may be, shall notify the Master Servicer or the Special
Servicer, as the case may be, 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.


 






     -277-


     


    

 


(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 the compliance with its obligations under the Sub-Servicing Agreement and the Master Servicer’s
obligations under this Agreement.


 


(c)       As
part of its servicing activities hereunder, the Master Servicer and the Special Servicer 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 of its Sub-Servicers 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.
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 shall have the right to remove a Sub-Servicer
retained by it pursuant to the terms of the related Sub-Servicing Agreement.


 


(d)       In
the event the Trustee or its designee becomes a 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 shall remain obligated
and responsible to the Trustee, 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 for which it is responsible,
and the Master Servicer 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.


 


(f)       The
Trustee, upon the request of the Master Servicer, 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 a 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


 



     -278-


     


    

 


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 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 that is an Excluded Loan with respect to the Directing
Certificateholder or the Holder of the majority of the Controlling Class, the consent of the Directing Certificateholder, except
to the extent necessary for the Special Servicer to comply with applicable regulatory requirements.


 


Section
3.21     Interest Reserve Account.


 


(a)       On
the P&I Advance Date occurring in each February and in any January that occurs in a year that is not a leap year (in each
case, unless the related Distribution Date is the final Distribution Date), the Certificate Administrator, in respect of the Actual/360
Mortgage Loans, shall deposit into the Interest Reserve Account, an amount equal to one (1) day’s interest on the Stated
Principal Balance of the Actual/360 Mortgage Loans as of the Distribution Date occurring in the month preceding the month in which
the P&I Advance Date occurs at the related Net Mortgage Rate, to the extent a full Periodic Payment or P&I Advance is
made in respect thereof (all amounts so deposited in any consecutive February and January, “Withheld Amounts”).


 


(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.

Section
3.22     Directing Certificateholder and Operating Advisor Contact with the Master Servicer and the
Special Servicer.  Within a reasonable time upon request from the Directing Certificateholder or the Operating Advisor,
as applicable, and no more often than on a monthly basis, each of the Master Servicer and the Special Servicer shall, without
charge, make a knowledgeable Servicing Officer via telephone available to verbally answer questions from (a) the Directing
Certificateholder ((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) upon the occurrence and during the continuance of any Control
Termination Event, the Operating Advisor (with respect to the Special Servicer only), regarding the performance and servicing
of the Mortgage 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 Certificateholder 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 MM 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 execute a certification substantially in the form of Exhibit P-1G
to this Agreement. Upon the resignation or removal of the existing Directing Certificateholder, any successor directing certificateholder
shall deliver to the parties to this Agreement a certification substantially in the form of Exhibit P-1G to this Agreement
prior to being recognized as the new Directing Certificateholder.


 


On
the Closing Date, the initial Risk Retention Consultation Party shall execute a certification substantially in the form of Exhibit P-1H
to this Agreement. Upon the resignation or removal of the existing Risk Retention Consultation Party, any successor Risk Retention
Consultation Party shall 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 the 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


 



     -280-


     


    

 


writing,
of the resignation of the Directing Certificateholder or the selection of 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.
The foregoing provisions shall not be applicable to the Directing Certificateholder that is a Loan-Specific Directing Certificateholder.
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 RR 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
RR 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 Certificateholder or Risk Retention Consultation Party, as applicable, 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 Certificateholder or Risk Retention
Consultation Party, as applicable, is identified to the Master Servicer or the Special Servicer, as applicable, 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 the Directing Certificateholder or Risk Retention Consultation Party, 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,
a list of each Controlling Class Certificateholder as reflected in the Certificate


 



     -281-


     


    

 


Register, including names and addresses. In
addition to the foregoing, within five (5) Business Days of receiving notice of the selection of a new 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) RREF III-D U 2017-C4, LLC, shall be the initial Directing Certificateholder (but not a Loan-Specific 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) Rialto Mortgage Finance, LLC 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 Risk Retention Consultation Party.


 


(f)       If
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 Certificateholder
may have special relationships and interests that conflict with those of Holders of one or more Classes of Certificates; (ii) the
Directing Certificateholder may act solely in the interests of the Holders of the Controlling Class or in its own interest; (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 Certificateholder that is not a Loan-Specific Directing Certificateholder may take actions that
favor interests of the Holders of one or more Classes including the Controlling Class over the interests of the Holders of one
or more other Classes of Certificates; and (v) the Directing Certificateholder shall have no liability whatsoever (other than,
in the case of the Directing Certificateholder that is not a Loan-Specific Directing Certificateholder, to a Controlling Class
Certificateholder) for having so acted as set forth in clauses (i) through (v) above, and no Certificateholder
may take any action whatsoever against the Directing Certificateholder or any director, officer, employee, agent or principal
of the Directing Certificateholder for having so acted.


 


Each
Certificateholder acknowledges and agrees, by its acceptance of its Certificates, that: (i) the Risk Retention Consultation
Party may have special relationships and interests that conflict with those of Holders of one or more Classes of Certificates;
(ii) the Risk Retention Consultation Party may act solely in the interests of the Holders of the RR Interest; (iii) the
Risk Retention Consultation Party does not have any liability or duties to the Holders of any Class of Certificates other than
the RR Interest; (iv) the Risk Retention Consultation Party may take actions that favor interests of the Holders of one or
more Classes including the RR Interest 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


 



     -282-


     


    

 


an RR Interest) 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)       (i)
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 Certificateholder contained in this Agreement shall also apply
to each Companion Holder with respect to information relating to the related Serviced AB Mortgage Loan or a Serviced Whole Loan,
as applicable; provided, however, that nothing in this subsection (g) 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 Certificateholder, the Risk Retention Consultation Party and any AB
Whole Loan Controlling Holder.


 


(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 related Serviced Whole Loan Controlling 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 within two (2) Business
Days of a request from the Master Servicer, the Special Servicer, Certificate Administrator, Trustee, 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 G Certificates and the Class G
Certificates are the Controlling Class 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 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 G 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


 



     -283-


     


    

 


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 irrevocably
waive its right to appoint the Directing Certificateholder and to exercise any of the rights of the 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 that became a Specially
Serviced Loan prior to the sale or transfer of the Class G 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 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 or (ii) any Consultation Termination
Event. Upon the Certificate Administrator’s determination that a Control Termination Event or a Consultation Termination
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 pursuant to clause (i) of the definition thereof, such special notice
shall state “A Control Termination Event has occurred due to the reduction of the Certificate Balance of the Class G Certificates
to less than 25% of the aggregate Original Certificate Balance thereof, with regard to the application of any Cumulative Appraisal
Reduction Amounts.”


 


In
the event that a Consultation Termination Event has occurred pursuant to clause (i) of the definition thereof, such special notice
shall state “A Consultation Termination Event has occurred due to the reduction of the Certificate Balance of the Class
G Certificates to less than 25% of the aggregate Original Certificate Balance thereof, without regard to the application of any
Cumulative Appraisal Reduction Amounts.”


 


In
the event that a Control Termination Event or Consultation Termination Event has occurred pursuant to clause (ii) of the definition
of each of such terms, such special notice shall state “A Control Termination Event and a Consultation Termination Event
has occurred due to the irrevocable waiver by the applicable 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 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
Certificates exists where such class’s aggregate Certificate


 



     -284-


     


    

 


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 G Certificate, and upon notice to the Certificate Administrator in the form of Exhibit MM
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 Certificateholder 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 Certificateholder or 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 determined to be
an Excluded Loan as to either such Risk Retention Consultation Party or the Holder of the majority of the RR Interest. In either
such case, in respect of the servicing of any such Excluded Loan, a Control Termination Event and Consultation Termination Event
shall be deemed to have occurred with respect to an Excluded Loan.


 


Section
3.24     Intercreditor Agreements.  (a)  The Master Servicer and Special
Servicer acknowledge and agree 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. The Master Servicer and the Special Servicer further acknowledge and agree that any AB Whole Loan Controlling Holder
will have the right to replace the applicable Special Servicer solely with respect to the related 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


 



     -285-


     


    

 


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 the case may be, 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 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 


 



     -286-


     


    

 


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 the occurrence and continuance of
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 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 set forth in the immediately preceding sentence,
the Special Servicer 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 Special Servicer 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 Special
Servicer 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.


 






     -287-


     


    

 


(h)       With
respect to the Serviced AB Whole Loan, notwithstanding any rights the Directing Certificateholder hereunder may have to consult
with respect to any action or other matter with respect to the servicing of such Serviced AB Whole Loan, to the extent the related
Intercreditor Agreement provides that such right is exercisable by the related Subordinate Companion Holder or its representative
or is exercisable in conjunction with the related Subordinate Companion Holder, then the Directing Certificateholder shall not
be permitted to exercise such right. Additionally, notwithstanding anything in this Agreement to the contrary, the Special Servicer
shall consult with, seek the approval of, or obtain the consent of the Subordinate Companion Holder or its representative with
respect to any matters with respect to the servicing of the related Subordinate Companion Loan to the extent required under the
related Intercreditor Agreement and shall not take such actions requiring consent of or consultation with such Subordinate Companion
Holder or its representative without such consent or consultation (or deemed consent or consultation). In addition, notwithstanding
anything to the contrary, the Master Servicer or Special Servicer, as applicable, shall deliver information, reports and notices
to the Subordinate Companion Holder or its representative as and to the extent required under the related Intercreditor Agreement; provided that
if such Subordinate Companion Holder is a Borrower Party with respect to the related Mortgage Loan, then such Subordinate Companion
Holder shall not be entitled to receive any information that would constitute Excluded Information if such AB Whole Loan were
an Excluded Controlling Class Loan. Each of the Master Servicer and the Special Servicer further acknowledges and agrees that
any AB Whole Loan Controlling Holder will have the right to exercise the rights of the Directing Certificateholder under this
Agreement to the extent provided for in, and subject to the terms of, the related Intercreditor Agreement.


 


(i)    
   To the extent not otherwise expressly included herein, any provisions required to be included herein
pursuant to any Intercreditor Agreement for a Whole Loan are deemed incorporated herein by reference, and the parties hereto
shall comply with those provisions as if set forth herein in full.


 


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. 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 Section 13.10(d).


 






     -288-


     


    

 


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 (other than as set forth in clause (y) below), the requirement to obtain a Rating
Agency Confirmation shall be deemed not to apply (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 the case may be, 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 has been appointed and currently
serves as a master servicer or special servicer, as applicable, on a transaction-level basis on a CMBS transaction currently rated
by Moody’s that currently has securities outstanding and for which Moody’s has not cited servicing concerns with respect
to the applicable replacement master servicer or special servicer as the sole or material factor in any qualification, downgrade
or withdrawal of the ratings (or placement on “watch status” in contemplation of a rating downgrade or withdrawal)
of securities in a commercial mortgage-backed securitization transaction serviced by the applicable replacement master servicer
or special servicer prior to the time of determination, if Moody’s 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, (iii) KBRA
has not publicly cited servicing concerns with respect to the applicable 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 rating downgrade or withdrawal) of securities in any other commercial mortgage-backed securitization transaction
and serviced by the applicable replacement master servicer or special servicer prior to the time of determination, if KBRA is
the non-responding Rating Agency or (iv) it is listed on S&P’s Select Servicer List as a U.S. Commercial Mortgage Master

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


 






     -289-


     


    

 


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 or to make a determination with respect to 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) all information made available to Privileged Persons on the Certificate Administrator’s Website (A) that relates
to any Specially Serviced Loan, and (B) that is contained in the CREFC® Servicer Watch List prepared by the
Master Servicer and (ii) 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.


 


(b)       The
Operating Advisor and its Affiliates will be obligated to keep confidential any information appropriately labeled “Privileged
Information” received from the Special Servicer or Directing Certificateholder in connection with the Directing Certificateholder’s
exercise of its rights under this Agreement (including, without limitation, in connection with the review and/or approval of any
Asset Status Report), subject to any Privileged Information Exemption, law, rule, regulation, order, judgment or decree requiring
the disclosure of such 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) After the occurrence and during the continuance of a Control Termination Event, based on the Operating Advisor’s review
of any assessment of compliance report, attestation report, Asset Status Report and other information (other than any communications
between the Directing Certificateholder and the Special Servicer that would be Privileged Information) delivered to the Operating
Advisor by the Special Servicer, including each Asset Status Report delivered during the prior calendar year, the Operating Advisor
shall (if any Mortgage Loans were Specially Serviced Loans during the prior calendar year) deliver to the Certificate Administrator
and the 17g-5 Information Provider within one hundred-twenty (120) days of the end of the prior calendar year for which a Control
Termination Event was continuing as of December 31, 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


 






     -290-


     


    

 


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),
setting forth the Operating Advisor’s assessment of the Special Servicer’s performance of its duties under this Agreement
during the prior calendar year on a “platform-level basis” with respect to the resolution and/or liquidation of Specially
Serviced Loans that the Special Servicer is responsible for servicing under this Agreement; provided, further, 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. Notwithstanding the foregoing, with respect to any Serviced AB Whole Loan, no Operating
Advisor Annual Report will be permitted to include an assessment of the Special Servicer’s performance in respect of such
Serviced AB Whole Loan until after the occurrence and during the continuance of an AB Control Appraisal Period under the related
Intercreditor Agreement. Subject to the restrictions in this Agreement, including, without limitation, Section 3.26(c),
each such Operating Advisor Annual Report shall (A) identify any material deviations (i) from the Servicing Standard
and (ii) from the Special Servicer’s obligations under this Agreement with respect to the resolution or liquidation
of Specially Serviced Loans or REO Properties that the Special Servicer is responsible for servicing under this Agreement (other
than with respect to any REO Property related to a Non-Serviced Mortgage Loan) and (B) comply with all of the confidentiality
requirements described in this Agreement regarding Privileged Information (subject to any permitted exceptions); provided
that the Operating Advisor shall not be required to report on any 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. Such Operating Advisor Annual Report shall be delivered to the Master Servicer, the
Special Servicer, 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 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. Only as used in this Section 3.26 in connection with the Operating Advisor Annual Report, the
term “platform-level basis” refers to the Special Servicer’s performance of its duties as they relate to the
resolution and/or liquidation of Specially Serviced Loans, 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, Asset Status Report and other
information delivered to the Operating Advisor by the Special Servicer (other than any communications between the Directing Certificateholder
and the Special Servicer that would be Privileged Information) pursuant to this Agreement. Notwithstanding the foregoing, no Operating
Advisor Annual Report shall be required from the


 






     -291-


     


    

 


Operating Advisor with respect to any calendar year as to which no Asset Status
Report was prepared by the Special Servicer in connection with a Specially Serviced Loan or REO Property.


 


(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 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 arising from such
limitations or prohibitions. 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 hereunder. 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 in the related Operating Advisor Annual Report, and the Operating Advisor shall
not be subject to any liability arising from its lack of access to Privileged Information.


 


(d)       Prior
to the occurrence and continuance of a Control Termination Event (or, with respect to a Serviced AB Whole Loan, prior to the occurrence
and continuance of both a Control Termination Event and a related AB Control Appraisal Period), the Special Servicer will forward
any Appraisal Reduction Amount and net present value calculations used in the Special Servicer’s determination of what course
of action to take in connection with the workout or liquidation of a Specially Serviced Loan to the Operating Advisor after such
calculations have been finalized. The Operating Advisor shall review such calculations but shall not opine on or take any affirmative
action with respect to such Appraisal Reduction Amount calculations and/or net present value calculations (except that if the
Operating Advisor discovers a mathematical error contained in such calculations, then the Operating Advisor shall notify the Special
Servicer of such error).


 


(e)       
(i) After the occurrence and during the continuance of a Control Termination Event, and with respect to any Serviced AB Whole
Loan, after the occurrence and during the continuance of both a Control Termination Event and an AB Control Appraisal Period,
after the calculation but prior to the utilization by the Special Servicer of any of the calculations related to (i)  Appraisal
Reduction Amounts or (ii) 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), 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 and verify 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(e), in the event the Operating Advisor does not agree with the mathematical calculations
of the Appraisal Reduction Amount (as


 






     -292-


     


    

 


calculated by the Special Servicer) or net present value 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. 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 either in the Master Servicer’s possession or, solely with respect to Non-Specially Serviced Loans, reasonably obtainable
by 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 such parties prompt
written notice of its determination.


 


(iii)       Notwithstanding
the foregoing, the consultation duties of the Operating Advisor set forth in this Agreement shall not be permitted to be exercised
by the Operating Advisor with respect to any Serviced AB Whole Loan until after the occurrence and during the continuance of both
a Control Termination Event (except with respect to any Mortgage Loan that is an Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class) and a related AB Control Appraisal Period.


 


(f)     
  [RESERVED].


 


(g)       The
Operating Advisor 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 the Directing
Certificateholder), other than (1) to the extent expressly required by this Agreement to the other parties to this Agreement with
a notice indicating that such information is Privileged Information, (2) pursuant to a Privileged Information Exception or (3)
where necessary to support specific findings or conclusions concerning allegations of deviations from the Servicing Standard (i)
in the Operating Advisor Annual Report or (ii) 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 and is continuing, the Directing Certificateholder
(with respect to any Mortgage Loan other than a Non-Serviced Whole Loan and other than any Mortgage Loan that is an Excluded Loan
with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class) 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 employees performing operating advisor functions for


 






     -293-


     


    

 


such Other Securitizations are not imputed to different
employees of the Operating Advisor performing the obligations hereunder. 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.


 


(h)       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).


 


(i)   
    As compensation for its activities hereunder, the Operating Advisor shall be entitled to receive the
Operating Advisor Fee on each Remittance Date with respect to each Mortgage Loan (excluding each Non-Serviced Mortgage Loan,
any Servicing Shift Mortgage Loan and each related Companion Loan) and each REO Loan. As to each Mortgage Loan and each REO
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 or REO Loan, as the case may be, and in the same manner as
interest is calculated on the related Mortgage Loan or REO 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
deemed to be due on such REO Loan is computed.


 


The
Operating Advisor shall be entitled to reimbursement of any Operating Advisor Expenses provided for pursuant to Section 6.04(a)
and/or Section 6.04(b), 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 has 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. 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
consistent with the Servicing Standard to collect the applicable Operating Advisor Consulting Fee from the related Mortgagor in
connection with such Major Decision that are consistent with the efforts in accordance with the Servicing Standard that the Master
Servicer or Special Servicer, as applicable, would use to collect any fee owed to it by a Mortgagor under the terms of the related
Mortgage Loan documents, 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


 






     -294-


     


    

 


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 in its capacity as operating advisor with respect to: (i) any
Non-Serviced Whole Loan or any related REO Property, (ii) any Serviced AB Whole Loan, prior to the occurrence and continuance
of both an AB Control Appraisal Period and a Control Termination Event or (iii) any Servicing Shift Whole Loan; provided,
further, that the Operating Advisor shall not be entitled to an Operating Advisor Consulting Fee with respect to any
Non-Serviced Whole Loan or Servicing Shift Whole Loan.


 


(j)       After
the occurrence and during the continuance of a Consultation Termination Event, the Operating Advisor may be removed upon (i) the
written direction of Holders of Certificates 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), (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 and (iii) receipt by the Trustee and the Certificate Administrator of Rating Agency
Confirmation from each Rating Agency (which confirmations will be obtained by the Certificate Administrator at the expense of
such Holders and will not constitute an additional expense of the Trust). The Certificate Administrator shall promptly provide
written notice to all 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 Certificates
in such regard. Upon the vote or written direction of Holders of Certificates evidencing 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.


 


(k)       After
the occurrence of an Operating Advisor Termination Event, the Trustee may, and upon the written direction of Holders of Certificates
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. No such termination shall terminate, change, reduce, or otherwise modify the rights and obligations
of the Operating Advisor that 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).
The Trustee may rely on a certification by the replacement Operating Advisor that it is an Eligible Operating Advisor. Upon any
termination of the Operating Advisor and appointment of a successor to the Operating Advisor, the Trustee will, as soon as possible,


 






     -295-


     


    

 


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, the Risk Retention Consultation Party, any Companion Holder and the Certificateholders.


 


(l)    
   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 Trustee 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.


 


(m)       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.


 


(n)       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, and (b) upon the appointment
of, and the acceptance of such appointment by, a successor operating advisor that is an Eligible Operating Advisor and receipt
by the Trustee of Rating Agency Confirmation from each Rating Agency. If no successor operating advisor has been so appointed
and accepted the appointment within thirty (30) days after the notice of resignation, the resigning Operating Advisor may petition
any court of competent jurisdiction for the appointment of 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.


 


(o)       In
the event there are no Classes of Certificates outstanding other than the Control Eligible Certificates, the Class Z Certificates,
the Class R Certificates and the RR Interest, then all of the rights and obligations of the Operating Advisor shall terminate
without payment of any termination fee (other than any rights or obligations that accrued prior to the date of such termination
(including accrued and unpaid compensation) and other than indemnification rights arising out of events occurring prior to such
termination). In connection with any termination pursuant to this Section 3.26(o), no successor operating advisor shall
be appointed.


 






     -296-


     


    

 


Upon receipt of written notice of such acts by a Responsible Officer of the Trustee, the Trustee shall provide the
Operating Advisor with prompt notice upon its termination pursuant to this Section 3.26(o).


 


(p)       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(i) and shall also remain entitled to any rights of indemnification provided hereunder.


 


(q)       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.


 


(r)     
  Neither the Operating Advisor 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 Operating Advisor or (ii) investments by an Affiliate of the Operating Advisor if the Operating Advisor and such
Affiliate maintain policies and procedures that (A) segregate personnel involved in the activities of the Operating
Advisor 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 Operating Advisor and its
personnel from gaining access to such Affiliate’s information regarding its investment activities.


 


(s)       The
Operating Advisor shall at all times be an Eligible Operating Advisor and if the Operating Advisor ceases to be an Eligible Operating
Advisor, the Operating Advisor shall immediately resign under Section 3.26(n) of this Agreement and the Trustee shall appoint
a successor operating advisor subject to and in accordance with this Section 3.26. Notwithstanding the foregoing, if the
Trustee is unable to find a successor operating advisor within thirty (30) days of the termination of the Operating Advisor, the
Depositor shall be permitted to find a replacement.


 


(t)  
     The Operating Advisor may delegate its duties and obligations 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 related to the Operating Advisor’s duties and obligations; provided that no agent or subcontractor may
(i) be affiliated with a Sponsor, the 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, the 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


 






     -297-


     


    

 


or other services with respect to any Mortgage 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.


 


(u)       With
respect to the determination of whether a Control Termination Event or Consultation Termination Event has occurred and is continuing,
or has terminated, the Operating Advisor is entitled to rely solely on its receipt from the Certificate Administrator of notice
thereof pursuant to Section 3.23(m), and, with respect to any obligations of the Operating Advisor that are performed only
after the occurrence and continuance of a Control Termination Event and/or Consultation Termination Event, the Operating Advisor
shall have no obligation to perform any such duties until the receipt of such notice or actual knowledge of the occurrence of
a Control Termination Event or Consultation Termination Event, as applicable.


 


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.


 


(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     Serviced Companion Noteholder Register. The Companion Paying Agent shall maintain a register (the “Serviced
Companion Noteholder Register”) with respect to each Serviced Companion Loan on which it will record the names and address
of, and wire transfer instructions for, the Serviced Companion Noteholders from time to time, to the extent such information is
provided in writing to it by each Serviced Companion Noteholder. The initial Serviced Companion Noteholders, along with their
respective name and address, are listed on Exhibit S hereto. In the event a Serviced Companion Noteholder transfers
a Serviced Companion Loan without notice to the Companion Paying Agent, the Companion Paying Agent shall have no liability for
any misdirected payment in such Serviced 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 any Serviced Companion Noteholder to any party hereto or
any successor Serviced Companion Noteholder 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 Serviced Companion Noteholder with respect to a Serviced Companion Loan that has been included in an Other Securitization shall
be provided to the Other Servicer under the Other Pooling and Servicing Agreement.

3.30 [RESERVED].


 


Section
3.31 [RESERVED].


 


Section
3.32     Litigation Control.


 


(a)       With
respect to any Mortgage Loan (other than a Non-Serviced Mortgage Loan), any Serviced Companion Loan or any related REO Loan or
related REO Property, the Special Servicer shall, in accordance with the Servicing Standard, direct, manage, prosecute and/or
defend any action brought by a Mortgagor, guarantor, or other obligor on the related Note or any Affiliates thereof (each a “Borrower-Related
Party”) against the Trust, the Master Servicer and/or the Special Servicer or any predecessor master servicer or special
servicer, and represent the interests of the Trust in any litigation relating to the rights and obligations of the Trust, or of
the Mortgagor or other Borrower-Related Party under the related Mortgage Loan documents, or with respect to the related Mortgaged
Property or other collateral securing such Mortgage Loan (or Serviced Whole Loan), or otherwise with respect to the enforcement
of the obligations of a Borrower-Related Party under the related Mortgage Loan documents (“Trust-Related Litigation”).
In the event that the Master Servicer is named in any Trust-Related Litigation but the Special Servicer is not named in such Trust-Related
Litigation (regardless of whether the Trust is named in such Trust-Related Litigation), the Master Servicer shall notify the Special
Servicer of such litigation as soon as practicable but in any event no later than within ten (10) Business Days of the Master
Servicer receiving service of such Trust-Related Litigation.


 


(b)       To
the extent the Master Servicer is named in the Trust-Related Litigation, and neither the Trust nor the Special Servicer is named,
in order to effectuate the role of the Special Servicer as contemplated by the immediately preceding Section 3.32(a), the
Master Servicer shall (i) provide monthly status reports to the Special Servicer, regarding such Trust-Related Litigation;
(ii) seek to have the Trust replace the Master Servicer as the appropriate party to the lawsuit; and (iii) so long as
the Master Servicer remains a party to the lawsuit, consult with and act at the direction of the Special Servicer with respect
to decisions and resolutions related to the interests of the Trust in such Trust-Related Litigation, including but not limited
to the selection of counsel; provided that the Master Servicer shall have the right to engage separate counsel relating
to claims against the Master Servicer to the extent set forth in Section 3.32(e); and provided, however,
that if there are claims against the Master Servicer and the Master Servicer has not determined that separate counsel is required
for such claims, such counsel shall be reasonably acceptable to the Master Servicer.


 


(c)       The
Special Servicer shall not (i) undertake (or direct the Master Servicer to undertake) any material settlement of any Trust-Related
Litigation or (ii) initiate any material Trust-Related Litigation unless and until it has notified in writing the Directing
Certificateholder (only if the related Mortgage Loan is not an Excluded Loan as to such party and prior to the occurrence and
continuance of a Consultation Termination Event) (to the extent the identity of the Directing Certificateholder is actually known
to the Special Servicer; provided that the Special Servicer shall make due inquiry of the Certificate Administrator as
to the identity of the Directing Certificateholder) and the related holder of any Serviced Companion Loan (if such matter affects
such related Serviced Companion Loan) (to the extent the identity of the holder of such Serviced Companion Loan is actually known
to the Special Servicer), and the Directing


 






     -302-


     


    

 


Certificateholder (only if the related Mortgage Loan is not an Excluded Loan with
respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class and prior to the occurrence
and continuation of a Control Termination Event) has not objected in writing within five (5) Business Days of having
been notified thereof and having been provided with all information that the Directing Certificateholder has reasonably requested
with respect thereto promptly following its receipt of the subject notice (it being understood and agreed that if such written
objection has not been received by the Special Servicer within such five (5) Business Day period, then the Directing Certificateholder
shall be deemed to have approved the taking of such action); provided that, if the Special Servicer determines (consistent
with the Servicing Standard) that immediate action is necessary to protect the interests of the Certificateholders and, with respect
to a Serviced Whole Loan, the related Companion Holders, the Special Servicer may take such action without waiting for the Directing
Certificateholder’s response.


 


(d)       Notwithstanding
the foregoing, neither the Special Servicer nor the Master Servicer shall follow any advice, direction or consultation provided
by the Directing Certificateholder or the Risk Retention Consultation Party (or any other party to this Agreement) that would
require or cause the Special Servicer or the Master Servicer, as applicable, to violate any applicable law, be inconsistent with
the Servicing Standard, require or cause the Special Servicer or the Master Servicer, as applicable, to violate provisions of
this Agreement, require or cause the Special Servicer or the Master Servicer, as applicable, to violate the terms of 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 REMIC created hereunder to fail to qualify as a REMIC, result in the imposition
of a “prohibited transaction” or “prohibited contribution” tax under the REMIC Provisions or materially
expand the scope of the Special Servicer’s or the Master Servicer’s, as the case may be, responsibilities under this
Agreement.


 


(e)       Notwithstanding
the right of the Special Servicer to represent the interests of the Trust in Trust-Related Litigation, and subject to the rights
of the Special Servicer to direct the Master Servicer’s actions in this Section 3.32, the Master Servicer shall retain
the right to make determinations relating to claims against the Master Servicer, including but not limited to the right to engage
separate counsel and to appear in any proceeding on its own behalf in the Master Servicer’s reasonable discretion, the cost
of which shall be subject to indemnification as and to the extent provided in this Agreement.


 


(f)     
  Further, nothing in this section shall require the Master Servicer to take or fail to take any action which, in
the Master Servicer’s good faith and reasonable judgment, may (i) result in a violation of the REMIC Provisions or
(ii) subject the Master Servicer to liability or materially expand the scope of the Master Servicer’s obligations
under this Agreement.


 


(g)       Notwithstanding
the Master Servicer’s right to make determinations relating to claims against the Master Servicer, the Special Servicer
shall have the right at any time in accordance with the Servicing Standard to (i) direct the Master Servicer to settle any
claims asserted against the Master Servicer (whether or not the Trust or the Special Servicer is named in any such claims or Trust-Related
Litigation) (and with respect to any material settlements, with the consent of or in consultation with the Directing Certificateholder
prior to the occurrence and continuance of a Control Termination Event or the occurrence and


 






     -303-


     


    

 


continuance of a Consultation Termination
Event, respectively (in each case, other than a Mortgage Loan that is an Excluded Loan as to such party)) and (ii) otherwise
reasonably direct the actions of the Master Servicer relating to claims against the Master Servicer (whether or not the Trust
or the Special Servicer is named in any such claims or Trust-Related Litigation), provided in either case that (A) such
settlement or other direction does not require any admission of liability or wrongdoing on the part of the Master Servicer, (B)
the cost of such settlement or any resulting judgment is and shall be paid by the Trust and payment of such cost or judgment is
provided for in this Agreement, (C) the Master Servicer is and shall be indemnified as and to the extent provided in this Agreement
for all costs and expenses of the Master Servicer incurred in defending and settling the Trust-Related Litigation and for any
judgment, (D) any such action taken by the Master Servicer at the direction of the Special Servicer shall be deemed (as to the
Master Servicer) to be in compliance with the Servicing Standard and (E) the Special Servicer provides the Master Servicer with
assurance reasonably satisfactory to the Master Servicer as to the items in clauses (A), (B) and (C).


 


(h)       In
the event both the Master Servicer and the Special Servicer or Trust are named in Trust-Related Litigation, the Master Servicer
and the Special Servicer shall cooperate with each other to afford the Master Servicer and the Special Servicer the rights afforded
to such party in this Section 3.32.


 


This
Section 3.32 shall not apply in the event the Special Servicer authorizes the Master Servicer, and the Master Servicer
agrees (both authority and agreement to be in writing), to make certain decisions or control certain Trust-Related Litigation
on behalf of the Trust in accordance with the Servicing Standard.


 


Notwithstanding
the foregoing, (i) in the event that any action, suit, litigation or proceeding names the Trustee in its individual capacity,
or in the event that any judgment is rendered against the Trustee in its individual capacity, the Trustee, upon prior written
notice to the Master Servicer or the Special Servicer, as the case may be, may retain counsel and appear in any such proceeding
on its own behalf in order to protect and represent its interests (but not to otherwise direct, manage or prosecute such litigation
or claim); (ii) in the event of any action, suit, litigation or proceeding, other than an action, suit, litigation or proceeding
relating to the enforcement of the obligations of a Mortgagor, guarantor or other obligor under the related Mortgage Loan documents,
or otherwise relating to one or more Mortgage Loans or Mortgaged Properties, neither the Master Servicer nor the Special Servicer
shall, without the prior written consent of the Trustee, (A) initiate an action, suit, litigation or proceeding in the name of
the Trustee, whether in such capacity or individually, (B) engage counsel to represent the Trustee, or (C) prepare, execute or
deliver any government filings, forms, permits, registrations or other documents or take any other similar actions with the intent
to cause, and that actually causes, the Trustee to be registered to do business in any state (provided that neither the Master
Servicer nor the Special Servicer shall be responsible for any delay due to the unwillingness of the Trustee to grant such consent);
and (iii) in the event that any court finds that the Trustee is a necessary party in respect of any action, suit, litigation
or proceeding relating to or arising from this Agreement or any Mortgage Loan, the Trustee shall have the right to retain counsel
and appear in any such proceeding on its own behalf in order to protect and represent its interests, whether as Trustee or individually
(but not to otherwise direct, manage or prosecute such litigation or claim); provided, however, that nothing in this Section
3.32(h) shall be interpreted to preclude the Special Servicer


 


 



     -304-


     


    

 


(with respect to any material Trust-Related Litigation, with
the consent or consultation of the Directing Certificateholder prior to the occurrence and continuance of a Control Termination
Event or the occurrence and continuance of a Consultation Termination Event, respectively, to the extent required in Section
3.32(c) and only to the extent such Mortgage Loan is not an Excluded Loan as to such party) from initiating any action, suit,
litigation or proceeding in its name as representative of the Trustee of the Trust.


 


Section
3.33     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
Information” followed by the applicable loan name and loan file to cmbsexcludedinformation@wellsfargo.com. For the avoidance
of doubt, any information that is not appropriately labeled and delivered in accordance with this Section 3.33 shall not
be separately posted as Excluded Information on the Certificate Administrator’s Website, and any information appropriately
labeled and delivered to the Certificate Administrator pursuant to this Section 3.33 shall be posted on the Certificate
Administrator’s Website under the “Excluded Information” section, as provided under Section 3.13. 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 3.33 until such party has received
written notice with respect to the related Excluded Controlling Class Loan in the form of Exhibit P-1E to this Agreement.
Nothing set forth in this Agreement shall prohibit the Directing Certificateholder 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 Certificateholder or such Controlling Class Certificateholder is not a Borrower Party and, if such Excluded
Information is not available on the Certificate Administrator’s Website, the 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.

(xxviii) twenty-eighth,
to the Holders of the Class R Certificates in respect of the Class UR Interest, the amount, if any, of the Available Funds

If,
in connection with any Distribution Date, the Certificate Administrator has reported the amount of an anticipated distribution
to DTC based on the receipt of payments as of the Determination Date and additional Periodic Payments, balloon payments or unscheduled
principal payments are subsequently received by the Master Servicer and required to be part of the Available Funds for such Distribution
Date, the Master Servicer shall promptly notify the Certificate Administrator and the Certificate Administrator will use commercially
reasonable efforts to cause DTC to make the revised distribution on a timely basis on such Distribution Date. None of the Master
Servicer, the Special Servicer or the Certificate Administrator shall be liable or held responsible for any resulting delay in
the making of such distribution to Certificateholders solely on the basis of the actions described in the preceding sentence.


 


(b)       [RESERVED].


 


(c)       On
each Distribution Date, each Lower-Tier Regular Interest shall be deemed to receive distributions in respect of principal or reimbursement
of Realized Losses in an amount equal to the amount of principal or reimbursement of Realized Losses actually distributable to
the Holders of the respective Related Certificates as provided in Sections 4.01(a), 4.01(d), 4.01(f)
and 4.01(i) such that at all times the Lower-Tier Principal Amount of each Class of Lower-Tier Regular Interests is equal
to the Certificate Balance of the Class of Related Certificates. On each Distribution Date, each Lower-Tier Regular Interest shall
be deemed to receive distributions in respect of interest in an amount equal to the Interest Distribution Amount in respect of
its Related Certificates plus (A) a pro rata portion of the Interest Distribution Amount in respect of (i) in the
case of the Class LA1, Class LA2, Class LASB, Class LA3 and Class LA4 Uncertificated Interests, the Class X-A
Certificates, (ii) in the case of the Class LAS, Class LB and Class LC Uncertificated Interests, the Class X-B Certificates,
(iii) in the case of the Class LD Uncertificated Interest, the Class X-D Certificates, (iv) in the case of the Class LE Uncertificated
Interest, the Class X-E Certificates, (v) in the case of the Class LF Uncertificated Interest, the Class X-F Certificates, (vi)
in the case of the Class LG Uncertificated Interest, the Class X-G Certificates, and (vi) in the case of the Class LNR Uncertificated
Interest, the Class X-NR Certificates, in each case, computed based on an interest rate equal to the excess of the Weighted Average
Net Mortgage Rate over the Pass-Through Rate of the Related Certificates and a notional amount equal to its related Lower-Tier
Principal Amount, in each case to the extent actually distributable thereon as provided in Section 4.01(a). Amounts distributable
pursuant to this paragraph are referred to herein collectively as the “Lower-Tier Distribution Amount”, and
shall be made by the Certificate Administrator by deeming such Lower-Tier Distribution Amount to be withdrawn from the Lower-Tier
REMIC Distribution Account to be deposited in the Upper-Tier REMIC Distribution Account.


 


As
of any date, the principal balance of each Lower-Tier Regular Interest shall equal the Certificate Balance of the Related Certificates
with respect thereto, as adjusted for the allocation of Realized Losses, as provided in Sections  4.04(b) and 4.04(c).
The initial principal balance of each Lower-Tier Regular Interest shall equal the respective Original Lower-Tier Principal Amount.
The Pass-Through Rate with respect to each Lower-Tier Regular Interest for


 






     -310-


     


    

 


any Distribution Date shall be the Weighted Average
Net Mortgage Rate for such Distribution Date.


 


Any
amount that remains in the Lower-Tier REMIC Distribution Account on each Distribution Date after distribution of the Lower-Tier
Distribution Amount and distribution of Prepayment Premiums and Yield Maintenance Charges pursuant to Section 4.01(e) shall
be distributed to the Holders of the Class R Certificates in respect of the Class LR Interest (but only to the extent
of the Available Funds for such Distribution Date remaining in the Lower-Tier REMIC Distribution Account, if any).


 


(d)       For
so long as the Certificate Balance of any Class of Certificates has been reduced to zero, such Class shall not be entitled to
any further distributions in respect of interest or principal other than reimbursement of Realized Losses (with interest as provided
herein) and other amounts provided for in this Section 4.01.


 


(e)       Funds
on deposit in the Distribution Account on each Distribution Date that represent Prepayment Premiums or Yield Maintenance Charges
received by the Trust with respect to any Mortgage Loan or REO Loan during the related Collection Period, in each case net of
any Liquidation Fees payable therefrom, shall be distributable as follows: if any Yield Maintenance Charge or Prepayment Premium
is collected during any particular Collection Period 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 or Prepayment Premium in the
following manner: (i) to each of the Class A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S,
Class B and Class C Certificates, the product of (A) such Yield Maintenance Charge or Prepayment Premium, (B) the related
Base Interest Fraction for such Class of Certificates, and (C) a fraction, the numerator of which is equal to the amount
of principal distributed to such Class of Certificates for that Distribution Date, and the denominator of which is the total amount
of principal distributed to such Classes of Principal Balance Certificates for that Distribution Date, (ii) to the Class X-A
Certificates, the excess, if any, of (A) the product of (I) such Yield Maintenance Charge or Prepayment Premium and (II) a
fraction, the numerator of which is equal to the amount of principal distributed to the Class A-1, Class A-2, Class A-SB,
Class A-3 and Class A-4 Certificates for that Distribution Date, and the denominator of which is the total amount of
principal distributed to the Class A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B and Class C Certificates
for that Distribution Date, over (B) the amount of such Yield Maintenance Charge or Prepayment Premium distributed to the
Class A-1, Class A-2, Class A-SB, Class A-3 and Class A-4 Certificates as described above, and (iii) to
the Class X-B Certificates, any remaining portion of such Yield Maintenance Charge or Prepayment Premium.


 


For
purposes of the first paragraph of this Section 4.01(e), 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 or Prepayment Premium,
and with respect to any Class of Principal Balance Certificates, shall be a fraction (A) the numerator of which is the greater
of (x) zero and (y) the difference between (i) the Pass-Through Rate on such Class for the related Distribution
Date, and (ii) the applicable Discount Rate and (B) the denominator of which is the difference between (i) the
Mortgage Rate on such Mortgage Loan and (ii) the applicable Discount Rate; provided that: (a) under no circumstances
will the Base


 






     -311-


     


    

 


Interest Fraction be greater than 1.0; (b) if the applicable Discount Rate is greater than or equal to the
Mortgage Rate on such Mortgage Loan and is greater than or equal to the Pass-Through Rate on such Class for the related Distribution
Date, then the Base Interest Fraction will equal zero; and (c) if the applicable Discount Rate is greater than or equal to
the Mortgage Rate on such Mortgage Loan and is less than the Pass-Through Rate on such Class for the related Distribution Date,
then the Base Interest Fraction shall be equal to 1.0. If a Mortgage Loan provides for a step-up in the Mortgage Rate, then the
Mortgage Rate used in the determination of the Base Interest Fraction will 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 Prepayment Premium or 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 Prepayment Premium or 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 Prepayment Premium or 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 Certificate Administrator
shall select a comparable publication as the source of the applicable yields of U.S. Treasury constant maturities.


 


No
Yield Maintenance Charge or Prepayment Premium shall be distributed to the Class X-D, Class X-E, Class X-F, Class X-G, Class X-NR,
Class D, Class E, Class F, Class G, Class NR, Class Z or Class R Certificates. After the Certificate Balances of the
Class A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B and Class C Certificates
have been reduced to zero, all Yield Maintenance Charges and Prepayment Premiums with respect to the Mortgage Loans shall be distributed
to the Class X-B Certificates.


 


All
distributions of Yield Maintenance Charges and Prepayment Premiums made in respect of the respective Classes of Regular Certificates
on each Distribution Date pursuant to Section 4.01(e) 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(c)
above.


 


(f)    
   On each Distribution Date, the Certificate Administrator shall determine if there will be any shortfalls in
interest or principal to any Class of Regular Certificates that would occur on such Distribution Date without the inclusion
of the Gain-on-Sale Remittance Amount in


 






     -312-


     


    

 


the definition of “Available Funds” (the aggregate amount of any such shortfalls together with any outstanding
Realized Losses and any interest thereon, the “Gain-on-Sale Entitlement Amount”) and shall remit (i) the lesser
of the Gain-on-Sale Entitlement Amount and all amounts on deposit in the Gain-on-Sale Reserve Account to the Collection Account
to be included as part of the Available Funds for such Distribution Date. Any amounts remaining in the Gain-on-Sale Reserve Account
after such distributions shall be applied to offset future shortfalls and Realized Losses, including interest thereon, with respect
to the Principal Balance Certificates and related Realized Losses in each case allocable to the Regular Certificates on subsequent
Distribution Dates. Upon termination of the Trust, any amounts remaining in the Gain-on-Sale Reserve Account shall be distributed
to the Holders of the Class R Certificates from the Lower-Tier REMIC in respect of the Class LR Interest.


 


(g)       All
distributions made with respect to each Class of Certificates on each Distribution Date shall be allocated pro rata among
the outstanding Certificates in such Class based on their respective Percentage Interests. Except as otherwise specifically provided
in Sections 4.01(h), 4.01(i) 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 wiring instructions no less than five (5) 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 by check mailed to such Certificateholder
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 for crediting the amount of such distribution to the accounts of its Depository Participants in accordance with
its normal procedures. Each Depository Participant shall be responsible for disbursing such distribution to the Certificate Owners
that it represents 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.


 


(h)       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:


 






     -313-


     


    

 


(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(h) 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
(1) 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, such to applicable law with respect to escheatment of funds.
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(h).


 


(i)     
  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), or Section 4.01(d), 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(h) as if such
Holder had failed to surrender its Certificates.


 


(j)     
  On each Distribution Date, any Excess Interest received during the related Collection Period with respect to any
ARD Loans shall be distributed to the Holders of the Excess Interest Certificates from the Excess Interest Distribution
Account. Excess Interest will not be available to pay any other amounts except for distributions on Excess Interest
Certificates.


 






     -314-


     


    

 


(k)       On
each Serviced Whole Loan Remittance Date, with respect to any Serviced Companion Loan, the Companion Paying Agent shall make withdrawals
and payments from the Companion Distribution Account for each Companion Loan in the following order of priority:


 


(i)    
   to pay to the Master Servicer for deposit into the Collection Account any amounts deposited by the Master
Servicer in the Companion Distribution Account not required to be deposited therein;


 


(ii)       to
the extent permitted under the related Intercreditor Agreement and not otherwise previously reimbursed, to pay the Trustee or
the 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;


 


(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 each Serviced Whole Loan Remittance Date (and on each additional
date required by this Agreement or the related Intercreditor Agreement) to the account of such Companion Holder or an agent therefor
appearing on the Serviced Companion Noteholder Register on the related Record Date (or, if no such account so appears or information
relating thereto is not provided at least five (5) 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 Serviced Companion Noteholder Register). Any such account
shall be located at a commercial bank in the United States.


 


On
the final 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 Remittance
Date.

the case of information furnished pursuant to clauses (i), (ix), (x), (xi), (xiv), (xxiii),
(xxiv) and (xxxiv) above, the amounts shall be expressed as a dollar amount in the aggregate for all Certificates
of each applicable Class and per Definitive Certificate.


 


The
Certificate Administrator has not obtained and shall not be deemed to have obtained actual knowledge of any information only by
virtue of its receipt and posting of such information to the Certificate Administrator’s website.


 


Within
a reasonable period of time after the end of each calendar year, the Certificate Administrator shall furnish to each Person who
at any time during the calendar year was a Holder of a Certificate, a statement containing the information set forth in clauses (i)
and (x) above as to the applicable Class, aggregated for such calendar year or applicable portion thereof during which
person was a Certificateholder, together with such other information as the Certificate Administrator deems necessary or desirable,
or that a Certificateholder or Certificate Owner reasonably requests, to enable Certificateholders to prepare their tax returns
for such calendar year. Such obligation of the Certificate Administrator shall be deemed to have been satisfied to the extent
that substantially comparable information shall be provided by the Certificate Administrator pursuant to any requirements of the
Code as from time to time are in force.


 


Upon
receipt of an Asset Review Report Summary from the Asset Representations Reviewer required to be delivered pursuant to Section
12.01(b), the Certificate Administrator shall (i) include such Asset Review Report Summary in Item 1B on the Form 10-D
for such period in which such Asset Review Report Summary was delivered, and (ii) post such Asset Review Report Summary to
the Certificate Administrator’s Website not later than two (2) Business Days after receipt of such Asset Review Report Summary
from the Asset Representations Reviewer.

(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 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 (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 as set forth herein. In connection with providing access to the Master Servicer’s Internet website, the
Master Servicer shall take reasonable measures to ensure that only such parties listed above may access such information





 






     -319-


     


    

 


including,
without limitation, requiring registration, a confidentiality agreement and acceptance of a disclaimer. Neither the Master Servicer
nor the Special Servicer, as the case may be, shall 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 Section 4.02(a), 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 Section 4.02(c), 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. None of the Certificate Administrator, the Trustee or 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 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).


 


(d)      Upon
the written request of a Certificateholder, any beneficial owner of a Certificate, or any prospective purchaser of a Certificate
that is a Qualified Institutional Buyer and is designated by a Certificateholder or a beneficial owner of a Certificate as such
and, in any case, has delivered an Investor Certification to the Depositor and the Certificate Administrator, as soon as reasonably
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 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





 






     -320-


     


    

 


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 Certificateholder 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 Certificateholder 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 Certificateholder or such Controlling Class
Certificateholder, as applicable, (at the expense of the Directing Certificateholder 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 Certificateholder or such Controlling Class Certificateholder, as applicable, through the
Certificate Administrator’s Website because the Directing Certificateholder 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 Certificateholder 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 Certificateholder 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 Certificateholder or a Controlling Class Certificateholder, as
applicable, of an Investor Certification substantially in the form of Exhibit P-1B that the Directing Certificateholder
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 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, (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


 






     -321-


     


    

 


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 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 such P&I Advances were made). The Master Servicer shall notify the Certificate Administrator of (i) the
aggregate amount of P&I Advances for a Distribution Date and (ii) the amount of any Nonrecoverable P&I Advances for
such Distribution Date, on or before two (2) Business Days prior to 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 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.


 


If
the Master Servicer or the Trustee makes a P&I Advance with respect to any Mortgage Loan that is part of a Whole Loan with
a related Serviced Companion Loan, then it shall provide to the related other master servicer and Other Trustee under the Other
Pooling and Servicing Agreement written notice of the amount of such P&I Advance with respect to such Mortgage Loan within
two (2) Business Days of making such P&I Advance.


 


If
the Master Servicer or the Trustee makes a P&I Advance with respect to a Non-Serviced Mortgage Loan, then it shall provide
to the related Non-Serviced Master Servicer and Non-Serviced Trustee written notice of the amount of such P&I Advance within
two (2) Business Days of making such P&I Advance.


 


(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 each Mortgage Loan, 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 Loan (including any Non-Serviced Mortgage Loan) and any REO Loan (other
than any portion of an REO Loan related to a Companion Loan) during the related Collection Period and were not received 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 delinquent in respect of its Balloon Payment as of the
P&I Advance Date (including any REO Loan (other than any portion of an REO Loan related to a Companion Loan) as to which the
related Balloon Payment would have been past due), an amount equal to the Assumed Scheduled Payment therefor. Subject to Section
4.03(c) below, the obligation of the Master Servicer to make such P&I Advances is mandatory, and with respect to any Mortgage


 






     -322-


     


    

 


Loan
(including any Non-Serviced Mortgage Loan) or REO Loan (other than any portion of an REO Loan related to a 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. No P&I Advances shall be made with respect
to any 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 Serviced Mortgage Loan, the Master Servicer, the Special Servicer
or the Trustee shall make its determination that a P&I Advance that has been made on such Serviced Mortgage Loan is a Nonrecoverable
Advance or that any proposed P&I Advance would, if made, constitute a Nonrecoverable Advance with respect to such Serviced
Mortgage Loan independently of any determination made by the applicable Other Servicer or Other Trustee, as the case may be, under
the applicable Other Pooling and Servicing Agreement in respect of the related Serviced Companion Loan. If the Master Servicer,
the Special Servicer or the Trustee determines that a proposed P&I Advance with respect to a Serviced Mortgage Loan, if made,
or any outstanding P&I Advance with respect to a Serviced Mortgage Loan previously made, would be, or is, as applicable, a
Nonrecoverable Advance, the Master Servicer or the Trustee, as applicable, shall provide the applicable Other 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 Other Servicer, as the case may be, that an Other Servicer or the Other Trustee has determined, in accordance
with the applicable Other Pooling and Servicing Agreement with respect to a Serviced Companion Loan, that any proposed advance
under the applicable Other Pooling and Servicing Agreement that is similar to a P&I Advance would be, or any outstanding advance
under such Other Pooling and Servicing Agreement that is similar to a P&I Advance is, a nonrecoverable advance, then the Master
Servicer, the Special 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 Serviced Mortgage Loan will be a Nonrecoverable P&I Advance. Thereafter,
in either case, the Master Servicer and the Trustee shall not be required to make any additional P&I Advances with respect
to the related 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 Serviced Mortgage Loan would not be a Nonrecoverable P&I
Advance, which determination may be as a result of consultation with the related Other Servicer, as the case may be, or otherwise.
For the avoidance of doubt, the Master Servicer, the Special Servicer or the Trustee, as the case may be, shall have the sole
discretion provided in this Agreement to determine that any future P&I Advance or outstanding P&I Advance would be, or
is, as applicable, a Nonrecoverable Advance.


 


With
respect to each Non-Serviced Mortgage Loan, the Master Servicer, the Special Servicer or the Trustee shall make its determination
(based on information provided by the applicable Non-Serviced Master Servicer and Non-Serviced Special Servicer) that a P&I
Advance that has been made on such Non-Serviced Mortgage Loan 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, the applicable Non-Serviced Special Servicer or the Non-Serviced Trustee,
as the case may be, under the applicable Non-Serviced


  






     -323-


     


    

 


PSA
in respect of the related Non-Serviced Companion Loan. If the Master Servicer, the Special Servicer or the Trustee 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, the Special Servicer or the Trustee, as applicable, 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, or the Non-Serviced Trustee 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, the Special 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 and the Trustee 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 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. For the avoidance
of doubt, the Master Servicer, the Special Servicer or the Trustee, as the case may be, shall have the sole discretion provided
in this Agreement to determine that any future P&I Advance or outstanding P&I Advance would be, or is, as applicable,
a Nonrecoverable Advance.


 


(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) if the related
Periodic Payment is received on or before 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.


 


(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, Prepayment Premiums, or Balloon Payments or make any P&I Advance with respect
to any Companion Loan and (ii) if an Appraisal Reduction Amount has been determined with respect to any Mortgage Loan (or,
in the case of a Non-Serviced Whole Loan,


 






     -324-


     


    

 


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) then in the event of subsequent delinquencies thereon, the interest
portion of the P&I Advance in respect of such Mortgage 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 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 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),
if any, and the denominator of which is equal to the Stated Principal Balance of such Mortgage 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 for the related Distribution Date.


 


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 Realized Loss for such Distribution Date. Any allocation of Realized Losses to a Class of Regular Certificates
shall be made by reducing the Certificate Balance thereof by the amount so allocated. Any Realized Losses so allocated to a Class
of Regular Certificates shall be allocated among the respective Certificates of such Class in proportion to the Percentage Interests
evidenced thereby. 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 Class of Certificates in respect of
which any such reimbursement is made. With respect to any Class of Principal Balance Certificates, to the extent any Nonrecoverable
Advances (plus interest thereon) that were reimbursed from principal collections on the Mortgage Loans and previously resulted
in a reduction of the Principal Distribution Amount are subsequently recovered on the related Mortgage Loan, the amount of such
recovery will be added to the Certificate Balance of the Class or Classes of Principal Balance Certificates that previously were
allocated Realized Losses, in sequential order according to the priority of payments for the Principal Balance Certificates (and
in the case of the Principal Balance Certificates that are Senior Certificates, 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 Principal Balance Certificates.


 


(b)      (i)  On
each Distribution Date, the Certificate Balances of the Principal Balance Certificates will be reduced without distribution, as
a write-off to the extent of any Realized Losses, if any, allocable to such Certificates with respect to such Distribution Date.
Any such write-off shall be allocated in Reverse Sequential Order.


 


(ii)      [RESERVED].


 


(c)      With
respect to any Distribution Date, any Realized Losses allocated to a Class of Principal Balance Certificates pursuant to Section
4.04(a) or Section 4.04(b) with


 






     -325-


     


    

 


respect
to such Distribution Date shall reduce the Lower-Tier Principal Amount of the Related Lower-Tier Regular Interest with respect
thereto as a write-off.


 


Section
4.05           Appraisal Reduction Amounts; Collateral Deficiency Amounts.
(a) For purposes of (x) determining the Controlling Class (and whether a Control Termination Event has occurred and
is continuing) and (y) determining the Voting Rights of the related Classes for purposes of removal of the Special Servicer
or the Operating Advisor, Appraisal Reduction Amounts and Cumulative Appraisal Reduction Amounts (with respect to a Serviced Whole
Loan, to the extent allocated to the related Mortgage Loan) shall be allocated to each Class of Principal Balance Certificates
solely to the extent of the related Appraisal Reduction Amount and Cumulative Appraisal Reduction Amount, respectively, in Reverse
Sequential Order to notionally reduce the related Certificate Balances until the Certificate Balance of each such Class is reduced
to zero.


 


As
of the first Determination Date following a Mortgage Loan (other than a Non-Serviced Mortgage 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, and all other information
relevant to a Collateral Deficiency Amount determination. Upon obtaining knowledge or receipt of notice by the Special Servicer
that a Non-Serviced Mortgage Loan has become an AB Modified Loan, the Special Servicer shall (i) promptly obtain 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 Special 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 Special Servicer of the appraisal and any other information set forth in the immediately preceding clause (i)
that the Special 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 in its possession 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 Loan has become
an AB Modified Loan, such party shall promptly notify the Special Servicer thereof. Upon reasonable prior written request, the
Master Servicer shall provide the Special Servicer with information in its possession that is reasonably required to calculate
or recalculate any Collateral Deficiency Amount. None of the Master Servicer, the Operating Advisor, the Trustee or the Certificate
Administrator shall calculate or verify any Collateral Deficiency Amount.


 


For
purposes of determining the Controlling Class and whether a Control Termination Event has occurred and is continuing, Collateral
Deficiency Amounts allocated to an AB Modified Loan will be allocated to each Class of Control Eligible Certificates in Reverse
Sequential Order to notionally reduce the related Certificate Balances until the Certificate Balance of each such Class of Control
Eligible Certificates is reduced to zero. 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 Certificates shall be allocated both
applicable Appraisal Reduction Amounts and applicable Collateral Deficiency Amounts (the


 






     -326-


     


    

 


sum
of which shall constitute the applicable Cumulative Appraisal Reduction Amount), in accordance with this Section 4.05(a),
but only to the extent of the Appraisal Reduction Amounts and Cumulative Appraisal Reduction Amounts.


 


With
respect to (i) any Appraisal Reduction Amount calculated for the purposes of 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.


 


The
Special Servicer shall promptly notify the Master Servicer and the Certificate Administrator, to the extent it receives such information,
of the amount of any Appraisal Reduction Amount, 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 shall be satisfied through
delivery of such Appraisal Reduction Amount as included in the CREFC® Appraisal Reduction Amount Template included
in the CREFC® Investor Reporting Package with respect to the Collateral Deficiency Amount and the Cumulative Appraisal Reduction
Amount) 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 Certificates that is determined at any time of determination
to no longer be the 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 a second Appraisal with respect to any Mortgage Loan (or Serviced Whole Loan)
for 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 Mortgage Loan (other than a Non-Serviced Mortgage Loan), the
Special Servicer shall use its reasonable efforts to cause such 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).


 


(ii)      Upon
receipt of any supplemental Appraisal pursuant to clause (i) above, the Special Servicer shall determine, in accordance
with the Servicing Standard, whether, based on its assessment of such supplemental Appraisal, any recalculation of the


 






     -327-


     


    

 


Appraisal
Reduction Amount or Collateral Deficiency Amount is warranted, and if so warranted, shall recalculate the Appraisal Reduction
Amount or Collateral Deficiency Amount, as applicable, based on such supplemental Appraisal and any information received from
the Master Servicer. If required by such recalculation, the Appraised-Out Class shall be reinstated as the Controlling Class and
each 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, as applicable. The Holders of an Appraised-Out
Class shall refrain from exercising any direction, control, consent and/or similar rights of the Controlling Class until such
time, if any, as the Class is reinstated as the Controlling Class (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 is warranted or (B) the Special Servicer recalculates the Appraisal Reduction Amount or Collateral Deficiency Amount,
as applicable, based on the supplemental Appraisal, the “Appraisal Review Period”). The rights of the Controlling
Class during each Appraisal Review Period shall be exercised by the next most senior Class of Control Eligible Certificates that
is not an Appraised-Out Class, if any.


 


(c)      With
respect to each Mortgage Loan (other than a Non-Serviced Mortgage Loan), and each Serviced Whole Loan as to which an Appraisal
Reduction Event has occurred (unless such Mortgage Loan or Serviced Whole Loan has become a Corrected Loan (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 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 as to such party) the Directing Certificateholder. Based upon such Appraisal
or internal valuation (or any Appraisal obtained in accordance with Section 4.05(b) above), 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) the Directing Certificateholder, 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 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





 






     -328-


     


    

 


Servicer
to comply with such duties or failure by the Master Servicer to otherwise comply with its obligations hereunder. Following the
Master Servicer’s receipt from the Special Servicer of the calculation of the Appraisal Reduction Amounts, the Master Servicer
shall provide such information to the Certificate Administrator in the form of the CREFC® Loan Periodic Update
File and the CREFC® Appraisal Reduction Template provided to it by the Special Servicer or such other report or
reports mutually agreed upon between the Master Servicer and the Certificate Administrator, and the Certificate Administrator
will calculate the Appraisal Reduction Amount and the Cumulative Appraisal Reduction Amount. Such report of the Appraisal Reduction
Amount 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 and
Other Trustee 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 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 Certificateholder 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 will 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
twelve-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 that is 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; 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. The Master Servicer shall not calculate Appraisal Reduction Amounts.


 


(d)      Any
Mortgage Loan (other than a 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


 






     -329-


     


    

 


into
account any amendment or modification of such Mortgage Loan, any related Serviced Companion Loan and any Serviced Whole Loan,
as applicable), 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 (until its principal balance
is notionally reduced to zero by such Appraisal Reduction Amounts) and second, pro rata, between the related Serviced AB
Mortgage Loan and any Serviced Pari Passu Companion Loans. 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, based upon their respective outstanding principal balances.


 


Section
4.06           Grantor Trust Reporting. (a) The parties intend
that the portions 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 Holders of the Class Z Certificates
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 Holders of the Class Z
Certificates their share of the Excess Interest and Excess Interest Distribution Account, in the time or times and in the manner
required by the Code.


 


(b)      If
the Certificate Administrator receives notice that the Class Z Certificates are held through a “middleman” as defined
by the WHFIT Regulations then the Grantor Trust shall be a WHFIT that is 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 the “middleman” identified in such notice is the only “middleman” unless the Depositor provides the
Certificate Administrator with the identities of other “middlemen” that are Certificateholders. The Certificate Administrator
shall be entitled to indemnification in accordance with the terms of this





 






     -330-


     


    

 


Agreement
in the event that the Internal Revenue Service makes a determination that the notice pursuant to 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.


 


(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 Holder of a Class Z Certificate, 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 Class Z 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.

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 Sections 3.13(b) and Section
3.13(d), the Mortgage Loans (excluding any Non-Serviced Mortgage Loan) 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 submitted and answered,
together with the answers thereto. Upon receipt of an Inquiry for the Master Servicer, the Special Servicer, Certificate Administrator
or the Operating

as applicable, and in the case of any Inquiry relating to a Non-Serviced Mortgage Loan, to the related Non-Serviced Master Servicer
or related Non-Serviced Special Servicer, as applicable, the Certificate Administrator shall forward the Inquiry to the appropriate
person (in the case of the Master Servicer to the following: REAM_InvestorRelations@wellsfargo.com), in each case within a commercially
reasonable period of time following receipt thereof. Following receipt of an Inquiry, the Master Servicer, the Special Servicer,
the Certificate Administrator or the Operating Advisor, as applicable, unless such party determines not to answer such Inquiry
as provided below, shall reply to the Inquiry, which reply of the Master Servicer, the Special Servicer or the Operating Advisor,
as applicable, shall be delivered to the Certificate Administrator by electronic mail. In the case of an Inquiry relating to a
Non-Serviced Mortgage Loan, the Certificate Administrator shall make reasonable efforts to obtain an answer from the related Non-Serviced
Master Servicer or the related Non-Serviced Special Servicer, as applicable; provided that the Certificate Administrator
shall not be responsible for the content of such answer or any delay or failure to obtain such answer. The Certificate Administrator
shall post (within a commercially reasonable period of time following preparation or receipt of such answer, as the case may be)
such Inquiry and the related answer to the Certificate Administrator’s Website. If the Certificate Administrator, the Master
Servicer, the Special Servicer or the Operating Advisor determines, in its respective sole discretion, that (i) any Inquiry
is beyond the scope of the topics described above, (ii) answering any Inquiry would not be in the best interests of the Trust
and/or the Certificateholders, (iii) answering any Inquiry would be in violation of applicable law, the applicable Mortgage
Loan documents or this Agreement, (iv) answering any Inquiry would materially increase the duties of, or result in significant
additional cost or expense to, the Master Servicer, the Special Servicer, the Certificate Administrator or the Operating Advisor,
as applicable, (v) answering any Inquiry would require the disclosure of Privileged Information (subject to the Privileged
Information Exception), (vi) that answering the inquiry would or is reasonably expected to result in a waiver of an attorney-client
privilege or the disclosure of attorney work product or (vii) answering any Inquiry is otherwise, for any reason, not advisable,
it shall not be required to answer such Inquiry and, in the case of the Master Servicer, the Special Servicer or the Operating
Advisor, shall promptly notify the Certificate Administrator of such determination. In addition, no party shall post or otherwise
disclose any direct communications with the Directing Certificateholder or the Risk Retention Consultation Party (in its capacity
as Risk Retention Consultation Party) as part of its response to any Inquiries. The Certificate Administrator shall notify the
Person who submitted such Inquiry in the event that the Inquiry will not be answered. Any notice by the Certificate Administrator
to the Person who submitted an Inquiry that will not be answered shall include the following statement: “Because the Pooling
and Servicing Agreement provides that the Master Servicer, the Special Servicer, the Certificate Administrator and the Operating
Advisor shall not answer an Inquiry if it determines, in its respective sole discretion, that (i) any Inquiry is beyond the
scope of the topics described in the Pooling and Servicing Agreement, (ii) answering any Inquiry would not be in the best
interests of the Trust and/or the Certificateholders, (iii) answering any Inquiry would be in violation of applicable law
or the applicable Mortgage Loan documents, (iv) answering any Inquiry would materially increase the duties of, or result
in significant additional costs or expenses to the Trustee, the Master Servicer, the Special Servicer, the Certificate Administrator
or Operating Advisor, as applicable, (v) answering any Inquiry would require the disclosure of Privileged Information, or
(vi) answering any Inquiry is otherwise, for any reason, not advisable, no inference should or

may
be drawn from the fact that the Master Servicer, the Special Servicer, the Certificate Administrator or the Operating Advisor
has declined to answer the Inquiry.” Answers posted on the Investor Q&A Forum will be attributable only to the respondent,
and shall not be deemed to be answers from any of the Depositor, the Underwriters or any of their respective Affiliates. None
of the Underwriters, Depositor, the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee or the Operating
Advisor or any of their respective Affiliates will certify to any of the information posted in the Investor Q&A Forum and
no such party shall have any responsibility or liability for the content of any such information. The Certificate Administrator
shall not be required to post to the Certificate Administrator’s Website any Inquiry or answer thereto that the Certificate
Administrator determines, in its sole discretion, is administrative or ministerial in nature. The Investor Q&A Forum will
not reflect questions, answers and other communications that are not submitted via the Certificate Administrator’s Website.
Notwithstanding the foregoing, the Operating Advisor shall not be required to respond to any Inquiries from Certificateholders
for which its 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
with respect to any other Certificateholder or Certificate Owner that has so registered. Any person registering to use the Investor
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 the Certificate Administrator that it wishes to be removed from the Investor Registry (which notice
may not be within forty-five (45) days of its registration), the Certificate Administrator shall promptly remove it from the Investor
Registry. The Certificate Administrator will not be responsible for verifying or validating any information submitted on the Investor
Registry, or for monitoring or otherwise maintaining the accuracy of any information thereon. The Certificate Administrator may
require acceptance of a waiver and disclaimer for access to the Investor Registry.

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

reports posted by the 17g-5 Information Provider in response to an inquiry may be posted on a separate website or web page accessible
by a link on the 17g-5 Information Provider’s Website. If the Certificate Administrator, the Master Servicer or the Special
Servicer determines, in its respective sole discretion, that (i) answering any Rating Agency Inquiry would be in violation
of applicable law, the Servicing Standard, this Agreement or any Mortgage Loan documents, (ii) answering any Rating Agency
Inquiry would or is reasonably expected to result in a waiver of an attorney-client privilege with, or the disclosure of attorney
work product, or (iii) (A) answering any Rating Agency Inquiry would materially increase the duties of, or result in
significant additional cost or expense to, the Certificate Administrator, the Master Servicer or the 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 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 Forum and
Document Request Tool. The 17g-5 Information Provider shall not be liable for the failure by any other such Person to so answer.

Certification and within 120 days following the Closing Date, deliver to the Certificate Administrator an electronic copy of the
Diligence Files for the Mortgage Loans that have been uploaded by the Mortgage Loan Sellers to the Designated Site. Upon receipt
thereof, the Certificate Administrator shall promptly upload the contents of each Diligence File actually


 






     -334-


     


    

 


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) 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 QQ hereto (which shall be sent via email to trustadministrationgroup@wellsfargo.com or submitted electronically
via the Certificate Administrator’s website). In no case whatsoever shall Certificateholders be permitted to access the
Secure Data Room. For the avoidance of doubt, the Certificate Administrator shall be under 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 Special Servicer 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.

Section
5.01           The Certificates. (a) The Certificates will be
substantially in the respective forms annexed hereto as Exhibit A-1 through and including Exhibit A-3,
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 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-A and Class X-B 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 Class X-D,
Class X-E, Class X-F, Class X-G and Class X-NR Certificates will be issuable only in minimum Denominations of authorized initial
Notional Amount of not less than $250,000 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) 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 any Class X Certificates and other than the 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

(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.


 


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
Purchasers to RREF III-D U 2017-C4, LLC) 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 sold to institutions that are non-United States Securities Persons in Offshore Transactions
in reliance on Regulation S under the Act shall initially be 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 RR Interest during the Transfer Restriction Period) offered and sold
to Qualified Institutional Buyers in reliance on Rule 144A under the Act (“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


 






     -337-


     


    

 


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 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 substantially 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, or, in the case of the RR
Interest, as provided in Section 5.02(e). For the avoidance of doubt, the Class Z and Class R Certificates and the
RR Interest shall only be in the form of Definitive Certificates.


 


(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)      During
the Transfer Restriction Period, any RR Interest shall only be held as a Definitive Certificate in the Retained Interest Safekeeping
Account by the Certificate Administrator (and each Retaining Party’s respective interest shall be tracked in the form of
an entry in the Certificate Administrator’s trust accounting system under the Retained Interest Safekeeping Account), for
the benefit of the Holder of the related Certificate. The Certificate Administrator shall hold the RR Interest in safekeeping
and shall release the same only upon receipt of written instructions from the Retaining Sponsor and the Depositor, and in accordance
with any authentication procedures as may be utilized by the Certificate Administrator and in accordance with Section 5.03(i). 
There shall be, and hereby is, established by the Certificate Administrator an account which will be designated the “Retained
Interest Safekeeping Account” and into which the RR Interest shall be held and which shall be governed by and subject to
this Agreement.  In addition, on and after the date hereof, the Certificate Administrator may establish any number of subaccounts
to the Retained Interest Safekeeping Account for each Retained Party.  The RR
Interest to be delivered in physical form to the Certificate Administrator shall be delivered as set forth herein. No amounts
distributable to the RR Interest shall be remitted to the Retained Interest Safekeeping Account, but shall be remitted directly
to each Retained Party in accordance with written instructions provided separately by each Retained Party to the Certificate Administrator. 
Under no circumstances by virtue of safekeeping the RR Interest shall the Certificate Administrator be obligated to bring legal
action or institute proceedings against any person on behalf of the Retained Parties. During the Transfer Restriction Period and
for such longer time as the Retaining Parties may request, the Certificate Administrator shall hold the Definitive Certificate
representing the RR Interest at the below location, or any other location; provided the Certificate Administrator has given
notice to each of the Retaining Parties of such new location:


 


Wells
Fargo Bank NA

On
the Closing Date, the Certificate Administrator shall deliver written confirmation to the Depositor and the Retaining Sponsor
substantially in the form of Exhibit SS to this Agreement evidencing its receipt of the RR Interest.


 


The
Certificate Administrator shall make available to each Retaining Party its respective account information as mutually agreed upon
by the Certificate Administrator and each respective Retaining Party, and in accordance with the Certificate Administrator’s
policies and procedures. Any transfer of a RR Interest shall be subject to Section 5.03(g), Section 5.03(i) and,
if applicable, Section 5.03(n).


 


Section
5.03           Registration of Transfer and Exchange of Certificates. (a)

being the “Certificate Registrar”). In such capacities, the Certificate Administrator shall be responsible
for, among other things, (i) maintaining the Certificate Register and a record of the

for exchange and registration of transfer, (ii) holding the RR Interest as Definitive Certificates on behalf of each Holder of
such Class and (iii) transmitting to the Depositor, the Master Servicer and the Special Servicer any notices from the Certificateholders.
No fee or service charge shall be imposed by the Certificate Registrar for its services in respect of any registration of Transfer
or exchange of any Certificate (other than Definitive Certificates) referred to in this Section 5.03.

and to increase, or cause to be increased, the Certificate Balance of the Temporary Regulation S Book-Entry Certificate by
the aggregate Certificate Balance of the beneficial interest in the Rule 144A Book-Entry Certificate to be exchanged, to

the transferee is otherwise entitled to hold its interest in the applicable Certificates in the form of an interest in the Regulation S
Book-Entry Certificate, without any registration of such Certificates under the Act (in which case such certificate shall enclose

Rule 144A Book-Entry Certificate that is being exchanged or transferred.


 


(e)      Temporary
Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate to Rule 144A Book-Entry Certificate.
If a holder of a beneficial interest in a Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate

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 such decrease and (3) with respect to
a transfer of an interest in the Temporary Regulation S Book-Entry Certificate for an interest in the Rule 144A Book-Entry
Certificate (i) during the Restricted Period, a certificate in the form of Exhibit K hereto given by the holder
of such beneficial interest and stating that the Person transferring such interest in the Temporary Regulation S Book-Entry
Certificate reasonably believes that the Person acquiring such interest in the Rule 144A Book-Entry Certificate is a Qualified
Institutional Buyer or (ii) after the Restricted Period, an Investment Representation Letter in the form of Exhibit C
attached hereto from the transferee to the effect that such transferee is a Qualified Institutional Buyer (an “Investment

then the Certificate Registrar shall instruct the Depository to reduce, or cause to be reduced, the Certificate Balance of the
Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate and to increase, or cause to be
increased, the Certificate Balance of the Rule 144A Book-Entry Certificate by the aggregate Certificate Balance of the beneficial

and the Certificate Registrar shall instruct the Depository, concurrently with such reduction, to credit, or cause to be credited,

Book-Entry Certificate and to debit, or cause to be debited, from the account of the Person making such transfer the beneficial
interest in the Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate that is being transferred.


 


(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 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


 






     -342-


     


    

 


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
or (b) the RR 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 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(c), Section 5.02(d), and subject to the issuance and transfer of the RR Interest during the Transfer
Restriction Period 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 RR Interest.  At all times, if a Transfer of any RR Interest after the Closing Date 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


 






     -343-


     


    

 


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 the Depositor with a medallion stamp guarantee 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.  Upon
receipt of the foregoing certifications, the Certificate Registrar shall, subject to Section 5.02(e) and Section 5.03(a),
reflect such RR Interest in the name of the prospective Transferee. For the avoidance of doubt, in no event shall an RR Interest
be held as a Book-Entry Certificate during the Transfer Restriction Period.


 


(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) and subsection (h) above (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 the Initial Purchasers or with respect to the RR Interest, a Mortgage Loan Seller acting as Retaining Sponsor) of any such
Certificate shall be made unless the Trustee and Certificate Administrator shall have received either (i) a representation
letter from the proposed purchaser or transferee of such Certificate substantially in the form of Exhibit F-1 attached
hereto, to the effect that such proposed purchaser or transferee is not and will not be (A) an employee benefit plan subject
to the fiduciary responsibility provisions of ERISA or a plan subject to Section 4975 of the Code, or a governmental plan
(as defined in Section 3(32) of ERISA), a church plan (as defined in Section 3(33) of ERISA) for which no election has
been made under Section 410(d) of the Code or any other plan subject to any federal, state or local law (“Similar
Law”) which is, to a material extent, similar to the


 






     -344-


     


    

 


foregoing
provisions of ERISA or the Code (each, a “Plan”) or (B) a person acting on behalf of or using the assets
of any such Plan (including an entity whose underlying assets include Plan assets by reason of investment in the entity by such
Plan and the application of Department of Labor Regulation § 2510.3-101, as modified by Section 3(42) of ERISA),
other than an insurance company using the assets of its general account under circumstances whereby the 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 is presented for registration
in the name of a purchaser or transferee that is any of the foregoing, an Opinion of Counsel in form and substance satisfactory
to the Trustee, the Certificate Administrator and the Depositor to the effect that the acquisition and holding of such Certificate
by such purchaser or transferee will not constitute or result in a non-exempt “prohibited transaction” within the
meaning of ERISA, Section 4975 of the Code or a non-exempt violation of any Similar Law, and will not subject the Trustee,
the Certificate Administrator, the Certificate Registrar, the Master Servicer, the Special Servicer, any Sub-Servicer, the Initial
Purchasers, the Underwriters, the Operating Advisor, the Asset Representations Reviewer or the Depositor to any obligation or
liability (including obligations or liabilities under ERISA, Section 4975 of the Code or any such Similar Law) in addition
to those set forth in the Agreement. The Trustee and Certificate Administrator shall not register the sale, transfer, pledge or
other disposition of any ERISA Restricted Certificate unless the Trustee and Certificate Administrator have received either the
representation letter described in clause (i) above or the Opinion of Counsel described in clause (ii)
above. The costs of any of the foregoing representation letters or Opinions of Counsel shall not be borne by any of the Depositor,
the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Initial Purchasers, the Underwriters,
the Operating Advisor, the Certificate Registrar, the Asset Representations Reviewer or the Trust. Each Certificate Owner of an
ERISA Restricted Certificate shall be deemed to represent that it is not and will not become a Person specified in clauses (i)(A)
or (i)(B) above. Any transfer, sale, pledge or other disposition of any ERISA Restricted Certificates 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.

     -346-


     


    

 


substantially
in the form of Exhibit F-2, stating that the prospective transferee is not and will not become a Plan or a person
acting on behalf of or using the assets of a Plan. Each Holder of a Class Z or Class R Certificate shall be deemed to represent
that it is not and will not become a Person specified in the second preceding sentence. Any attempted or purported transfer in
violation of these transfer restrictions 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.


 


Each
Person who has or acquires any Residual Ownership Interest shall be deemed by the acceptance or acquisition of such Residual Ownership
Interest to 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 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 tax 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


 






     -347-


     


    

 


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 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)      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 such other 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.

the Class R Certificates) to an Institutional Accredited Investor that is not a Qualified Institutional Buyer, and in each

States or any other jurisdiction.


 


(iii)          Such
Certificate Owner understands that, if the purchaser of a Non-Registered Certificate is not a Qualified Institution Buyer or a
non-United States Securities Person, the Non-Registered Certificates purchased by such purchaser may not be transferred in book-entry

restrictions, as described in this Section 5.03(r).


 


(iv)          Such
Certificate Owner is duly authorized to purchase the Non-Registered Certificates and its purchase of investments having the characteristics

charter, trust instrument or other operative document, investment guidelines or list of permissible or impermissible investments
that is applicable to such Certificate Owner.

Certificate is surrendered to the Certificate Registrar, or the Certificate Registrar receives evidence to its satisfaction

authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like tenor and interest in the Trust. In connection with the issuance of any new Certificate under this Section
5.04, the Certificate Registrar may require the payment of a sum sufficient to cover any expenses (including the fees and

or Certificate Owner (if applicable) that has provided an Investor Certification, the Certificate Administrator shall

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 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

     -352-


     


    

 


(b)          In
connection with any vote administered pursuant to this Agreement, voting Holders shall be required to certify their holdings in

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

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.

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 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.

adverse effect on the ability of the applicable Special Servicer to perform its obligations hereunder.

Section
6.02     Liability of the Depositor, the Master Servicer, the Operating Advisor, the Special
Servicer and the Asset Representations Reviewer. The Depositor, the Master Servicer, the Operating Advisor, the Special
Servicer and the Asset Representations Reviewer shall be liable in accordance herewith only to the extent of the respective
obligations specifically imposed upon and undertaken by the Depositor, the Master Servicer, the Operating Advisor, the
Special Servicer and the Asset Representations Reviewer herein.


 


Section
6.03     Merger, Consolidation or Conversion of the Depositor, the Master Servicer, the
Operating Advisor, the Special Servicer or the Asset Representations Reviewer. (a)  Subject to 6.03(b)
below, each of the Depositor, the Master Servicer and the Special Servicer will keep in full effect its existence, rights and
franchises as an entity under the laws of the jurisdiction of its incorporation or organization, and each will obtain and
preserve its qualification to do business as a foreign entity in each jurisdiction in which qualification is or shall be
necessary to protect the validity and enforceability of this Agreement, the Certificates or any of the Mortgage Loans or
Companion Loans and to perform its respective duties under this Agreement.


 


(b)          Each
of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer 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


 






     -360-


     


    

 


received from each Rating Agency with respect to the Classes of Certificates and, with respect to 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
or the Operating Advisor enters into a merger and the Master Servicer, the Special Servicer or the Operating Advisor, as applicable,
is the surviving entity under applicable law, the Master Servicer, the Special Servicer or the Operating Advisor, 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 Serviced 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 or
the Operating Advisor 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 may be, notifies
the Master Servicer, the Special Servicer or the Operating Advisor, as applicable, 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 pursuant
hereto, such termination to be effected in the manner set forth in Section 7.01.


 


(i)          The
Asset Representations Reviewer shall keep in full effect its existence and rights as an entity under the laws of the jurisdiction
of its organization, and shall be


 






     -361-


     


    

 


in compliance with the laws of all jurisdictions to the extent necessary to perform its duties
under this Agreement.


 


(ii)          Any
Person into which the Asset Representations Reviewer may be merged or consolidated, or any Person resulting from any merger or
consolidation to which the Asset Representations Reviewer shall be a party, or any Person succeeding to the business of the Asset
Representations Reviewer, shall be the successor of the Asset Representations Reviewer hereunder, and shall be deemed to have
assumed all of the liabilities and obligations of such Asset Representations Reviewer hereunder, without the execution or filing
of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided,
however, that the Trustee has received a Rating Agency Confirmation with respect to such successor or surviving Person.


 


Section
6.04     Limitation on Liability of the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer and Others. (a)  None of the Depositor, the Master
Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special Servicer, the Operating Advisor,
the Asset Representations Reviewer or any of the partners, directors, officers, shareholders, members, managers, employees or
agents of any of the foregoing shall be under any liability to the Trust, the Certificateholders or the Companion Holders for
any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in
judgment; provided, however, that this provision shall not protect the Depositor, the Master Servicer
(including in its capacity as Companion Paying Agent, if applicable), the Special Servicer, the Operating Advisor, the Asset
Representations Reviewer or any such Person against any breach of warranties or representations made herein or any liability
which would otherwise be imposed by reason of willful misconduct, bad faith or negligence in the performance of such
party’s duties or by reason of negligent disregard of such party’s obligations and duties hereunder. The
Depositor, the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer and any partner, director, officer, shareholder, member, manager,
employee or agent of the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent, if applicable),
the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, and any of the partners, directors,
officers, shareholders, members, managers, employees or agents of any of the foregoing may rely on any document of any kind
which, prima facie, is properly executed and submitted by any Person respecting any matters arising hereunder. The
Depositor, the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special
Servicer, the Asset Representations Reviewer and the Operating Advisor and any partner, director, officer, shareholder,
member, manager, employee or agent of any of the foregoing shall be indemnified and held harmless by the Trust against any
and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other
costs, liabilities, fees and expenses incurred in connection with any actual or threatened legal or administrative action
(whether in equity or at law) or claim relating to this Agreement, the Mortgage Loans, the Companion Loans or the
Certificates, other than any loss, liability or expense: (i) specifically required to be borne thereby pursuant to the
terms hereof; (ii) incurred in connection with any breach of a representation or warranty made by it herein;
(iii) incurred by reason of bad faith, willful misconduct or negligence in the performance of its obligations or


 






     -362-


     


    

 


duties
hereunder, or by reason of negligent disregard of such obligations or duties; or (iv) in the case of the Depositor and
any of its partners, directors, officers, shareholders, members, managers, employees and agents, incurred in connection with
any violation by any of them of any state or federal securities law. In addition, absent actual fraud (as determined by a
final non-appealable court order), neither the Trustee nor the Certificate Administrator (including in its capacity as
Custodian, Certificate Registrar and 17g-5 Information Provider) 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. Each of the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special
Servicer, the Asset Representations Reviewer and the Operating Advisor conclusively may rely on, and shall be protected in
acting or refraining from acting upon, any resolution, officer’s certificate, certificate of auditors or any other
certificate, statement, instrument, opinion, report, notice, request, consent, order, financial statement, agreement,
appraisal, bond or other document (in electronic or paper format) as contemplated by and in accordance with this Agreement
and reasonably believed or in good faith believed by the Master Servicer (including in its capacity as Companion Paying
Agent, if applicable), 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, if applicable), 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, if applicable), the Special


 






     -363-


     


    

 


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).


 


(c)          Each
of the Master Servicer and the Special Servicer, as applicable, agrees to indemnify the Depositor, the Trustee, the related Serviced
Companion Noteholder, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer, the Master Servicer
(including in its capacity as Companion Paying Agent, if applicable) (in the case of the Special Servicer), the Special Servicer
(in the case 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 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 Servicer, as the case may be, of its duties and obligations hereunder or by reason of breach of
any representations or warranties made herein by the Master Servicer or the Special Servicer, as applicable. The Trustee, the
Certificate Administrator, the Depositor, the Asset Representations Reviewer or the Operating Advisor, as the case may be, shall
immediately notify the Master Servicer or the Special Servicer, as applicable, if a claim is made by a third party with respect
to this Agreement or the Mortgage Loans entitling the Trust to indemnification hereunder, whereupon the Master Servicer or the
Special Servicer, as the case may be, shall assume the defense of such claim (with counsel reasonably satisfactory to the Trustee,
the 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
may be, shall not affect any rights any of the foregoing Persons may have to indemnification under this Agreement or otherwise,
unless the Master Servicer’s or the Special Servicer’s, as the case may be, defense of such claim is materially prejudiced
thereby.


 


Each
of the Master Servicer and the Special Servicer shall indemnify and hold harmless the Depositor 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 or its Affiliates that arise out of or are based upon, severally and not jointly (i) a breach by the Master
Servicer or Special Servicer, as applicable, of any obligation it has to deliver information to the 17g-5 Information Provider
as set forth in this Agreement, including Section 3.07(a), Section 3.08, Section 3.09(e), Section 3.12,
Section 3.17(c) and Section 3.18(g) or (ii) a breach of any obligation it has set forth in Sections 3.13(e),
(h) and (j).


 


(d)          Each
of the Trustee and the Certificate Administrator (including in its role as Custodian), respectively agrees to indemnify the Depositor,
the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special Servicer, the Certificate
Administrator (in the case of the Trustee), the Trustee (in the case of the Certificate Administrator), the Operating Advisor,

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 that any of them may sustain arising
from or as a result of any willful misconduct, bad faith or negligence of the Trustee or the Certificate Administrator, respectively,
in the performance of its obligations and duties under this Agreement or by reason of negligent disregard by the Trustee or the
Certificate Administrator, respectively, of its duties and obligations hereunder or by reason of breach of any representations
or warranties made herein; provided that such indemnity shall not cover indirect or consequential damages. The Depositor,
the Master Servicer, the Special Servicer, the Asset Representations Reviewer or the Operating Advisor, as the case may be, shall
immediately notify the Trustee and the Certificate Administrator, respectively, if a claim is made by a third party with respect
to this Agreement or the Mortgage Loans entitling the Trust to indemnification hereunder, whereupon the Trustee or the Certificate
Administrator shall assume the defense of such claim (with counsel reasonably satisfactory to the Depositor, the Master Servicer
(including in its capacity as Companion Paying Agent, if applicable), the Special Servicer, the Asset Representations Reviewer
or the Operating Advisor) 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
Trustee or the Certificate Administrator shall not affect any rights any of the foregoing Persons may have to indemnification
under this Agreement or otherwise, unless the Trustee’s or the Certificate Administrator’s defense of such claim is
materially prejudiced thereby.


 


(e)          The
Depositor agrees to indemnify the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special
Servicer, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer 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 that any of them may sustain arising from or as a result of any willful misconduct,
bad faith or negligence of the Depositor, in the performance of its obligations and duties under this Agreement or by reason of
negligent disregard by the Depositor of its duties and obligations hereunder or by reason of breach of any representations or
warranties made herein; provided that such indemnity shall not cover indirect or consequential damages. The Master Servicer,
the Special Servicer, the Trustee, the Certificate Administrator, the Asset Representations Reviewer or the Operating Advisor,
as the case may be, shall immediately notify the Depositor if a claim is made by a third party with respect to this Agreement,
whereupon the Depositor shall assume the defense of such claim (with counsel reasonably satisfactory to the Master Servicer (including
in its capacity as Companion Paying Agent, if applicable) or the Special Servicer, as the case may be) 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 Depositor shall not affect any rights any of the foregoing
Persons may have to indemnification under this Agreement or otherwise, unless the Depositor’s defense of such claim is materially
prejudiced thereby.


 






     -365-


     


    

 


(f)          The
Operating Advisor agrees to indemnify the Master Servicer (including in its capacity as Companion Paying Agent, if applicable),
the Special Servicer, the Trustee, the Certificate Administrator, the Depositor, the Asset Representations Reviewer 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 that any of them may sustain arising from or as a result of any willful misconduct,
bad faith or negligence of the Operating Advisor, in the performance of its obligations and duties under this Agreement or by
reason of negligent disregard by the Operating Advisor of its duties and obligations hereunder or by reason of breach of any representations
or warranties made herein; provided that such indemnity shall not cover indirect or consequential damages. The Master Servicer,
the Special Servicer, the Trustee, the Certificate Administrator, the Asset Representations Reviewer or the Depositor, as the
case may be, shall immediately notify the Operating Advisor if a claim is made by a third party with respect to this Agreement
or the Mortgage Loans entitling the Trust to indemnification hereunder, whereupon the Operating Advisor shall assume the defense
of such claim (with counsel reasonably satisfactory to the Master Servicer (including in its capacity as Companion Paying Agent),
the Special Servicer, the Trustee, the Certificate Administrator, 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 Operating Advisor shall not affect any
rights any of the foregoing Persons may have to indemnification under this Agreement or otherwise, unless the Operating Advisor’s
defense of such claim is materially prejudiced thereby.


 


(g)          Neither
the Operating Advisor nor its Affiliates or any of the partners, directors, officers, shareholders, members, managers, employees
or agents of the Operating Advisor shall be under any liability to any Certificateholder for any action taken or for refraining
from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however,
that this provision shall not protect the Operating Advisor against any liability which would otherwise be imposed by reason of
willful misconduct, bad faith or negligence in the performance of duties or by reason of negligent disregard of obligations and
duties hereunder.


 


(h)          The
Asset Representations Reviewer agrees to indemnify the Master Servicer (including in its capacity as Companion Paying Agent, if
applicable), the Special Servicer, the Trustee, the Certificate Administrator, the Depositor, the Operating Advisor 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 that any of them may sustain arising from or as a result of any willful misconduct,
bad faith or negligence of the Asset Representations Reviewer, in the performance of its obligations and duties under this Agreement
or by reason of negligent disregard by the Asset Representations Reviewer of its duties and obligations hereunder or by reason
of breach of any representations or warranties made herein; provided that such indemnity shall not cover indirect or consequential
damages. The Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Operating Advisor or the Depositor,
as the case may be, shall immediately notify the Asset Representations Reviewer if a claim is made by a third party with


 






     -366-


     


    

 


respect
to this Agreement or the Mortgage Loans entitling the Trust to indemnification hereunder, whereupon the Asset Representations
Reviewer shall assume the defense of such claim (with counsel reasonably satisfactory to the Master Servicer (including in its
capacity as Companion Paying Agent, if applicable), the Special Servicer, the Trustee, the Certificate Administrator, the Operating
Advisor 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
Asset Representations Reviewer shall not affect any rights any of the foregoing Persons may have to indemnification under this
Agreement or otherwise, unless the Asset Representations Reviewer’s defense of such claim is materially prejudiced thereby.


 


(i)          The
applicable Non-Serviced Master Servicer, Non-Serviced Special Servicer, Non-Serviced Paying Agent, Non-Serviced Operating Advisor
(if any), Non-Serviced Asset Representations Reviewer, Non-Serviced Depositor, Non-Serviced Trustee, and any of their respective
partners, directors, officers, shareholders, members, managers, employees or agents (collectively, the “Non-Serviced
Indemnified Parties”), shall be indemnified by the Trust and held harmless against the Trust’s pro rata
share (subject to the applicable Non-Serviced Intercreditor Agreement) of any and all claims, losses, penalties, fines, forfeitures,
legal fees and related costs, judgments, and any other costs, liabilities, fees and expenses incurred in connection with the servicing
and administration of a Non-Serviced Mortgage Loan and the related Non-Serviced Mortgaged Property (or with respect to the Non-Serviced
Operating Advisor and/or Non-Serviced Asset Representations Reviewer, incurred in connection with the provision of services for
such Non-Serviced Mortgage Loan) under the applicable Non-Serviced PSA (as and to the same extent the applicable Non-Serviced
Trust is required to indemnify such parties in respect of other mortgage loans in the applicable Non-Serviced Trust pursuant to
the terms of the related Non-Serviced PSA).


 


The
indemnification provided herein shall survive the termination of this Agreement and the termination or resignation of the Master
Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special Servicer, the Trustee, the Certificate
Administrator, the Operating Advisor or the Asset Representations Reviewer.


 


(j)          For
purposes of this Section 6.04 and Section 11.12, the Master Servicer or the Special Servicer, as the case may be,
will be deemed not to have engaged in willful misconduct or committed bad faith or negligence in the performance of their respective
obligations and duties hereunder or acted in negligent disregard of such obligations and duties if the Master Servicer or the
Special Servicer, as applicable, fails to follow any terms of any Mortgage Loan documents because the Master Servicer or the Special
Servicer, as applicable, in accordance with the Servicing Standard, determines that compliance with such terms would or potentially
would cause an Adverse REMIC Event or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions
of the Code (for which determination the Master Servicer and the Special Servicer will be entitled to rely on advice of counsel,
the cost of which will be reimbursed as an additional expense of the Trust).


 


Section
6.05     Depositor, Master Servicer and Special Servicer Not to Resign. Subject to the
provisions of Section 6.03, neither the Master Servicer nor the Special Servicer shall resign from their respective
obligations and duties hereby imposed on each of them except


 






     -367-


     


    

 


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 (which may be appointed by the
resigning 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.
Unless applicable law requires the resignation of the Master Servicer or the Special Servicer (as the case may be) to be
effective immediately, and the Opinion of Counsel delivered pursuant to the prior sentence so states, no such resignation by
the Master Servicer or the Special Servicer under clause (a) above shall become effective until the Trustee or a
successor master servicer or 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 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
Certificateholder, such approval not to be unreasonably withheld. The resigning party shall pay all reasonable out-of-pocket
costs and expenses (including reasonable out-of-pocket 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 the 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 the obligations of the Master Servicer and the Special Servicer hereunder
and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of the Master Servicer
and the Special Servicer hereunder or exercise the rights of the Master Servicer or the Special Servicer, as 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


 






     -368-


     


    

 


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 Certificateholder and the Risk Retention Consultation Party.
(a)  (A) Other than with respect to any Serviced AB Whole Loan that is not subject to an AB Control Appraisal
Period, for so long as no Control Termination Event has occurred and is continuing, the Directing Certificateholder shall be
entitled to advise (1) the Special Servicer with respect to all Major Decisions for all Mortgage Loans (other than any
Excluded Loan with respect to the Directing Certificateholder), (2) the Special Servicer with respect to all Mortgage
Loans, as to the Special Servicer Decisions described in clauses (d), (e), (f) and (g) of the
definition of “Special Servicer Decision” and (3) the Master Servicer to the extent the Directing
Certificateholder’s consent is required by clauses (x) and (xii) of the definition of Master
Servicer Decision, and (B) the Risk Retention Consultation Party shall (other than with respect to an Excluded Loan with
respect to the Risk Retention Consultation Party) be entitled to consult on a strictly non-binding basis with the Special
Servicer (1) prior to the occurrence and continuance of a Consultation Termination Event, with respect to any Major Decision
in respect of a Specially Serviced Loan and, (2) after the occurrence and during the continuance of a Consultation
Termination Event, with respect to any Major Decision in respect of any Mortgage Loan. For the avoidance of doubt, any
consultation with the Risk Retention Consultation Party under this Agreement shall occur only upon request of the
Risk Retention Consultation Party with respect to any individual triggering event, and any such consultation shall be on a
strictly non-binding basis and shall be subject to all limitations with respect to the procedures and timing of such
consultation set forth in this Section 6.08.


 


Notwithstanding
anything herein to the contrary, except as set forth in, and in any event subject to, the third and fourth paragraphs of this
Section 6.08(a) and Section 6.08(b), for so long as no Control Termination Event has occurred and is continuing,
the Special Servicer shall only be permitted to take any of the following actions (each, a “Major Decision”)
as to which the Directing Certificateholder has consented in writing within ten (10) Business Days after the Directing Certificateholder’s
receipt of the Special Servicer’s written recommendation and analysis and all information reasonably requested by the Directing
Certificateholder, and reasonably available to the Special Servicer in order to grant or withhold such consent (provided
that if such written consent has not been received by the Special Servicer within such ten (10) Business Day period, then
the Directing Certificateholder will be deemed to have approved such action):


 


(i)          any
proposed or actual foreclosure upon or comparable conversion (which may include acquisition of an REO Property) of the ownership
of properties securing any Mortgage Loan (other than a Non-Serviced Mortgage Loan) and Serviced Companion Loan that comes into
and continues in default;


 






     -369-


     


    

 


(ii)          any

(other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan or any extension of the maturity date of such Mortgage Loan or
Serviced Whole Loan other than in connection with a maturity default if a refinancing or sale is expected within 120 days
as provided in clause (viii) of the definition of “Master Servicer Decision”;


 


(iii)          following
a default or an event of default with respect to a Mortgage Loan or Serviced Whole Loan, any exercise of remedies, including the
acceleration of the Mortgage Loan or Serviced Whole Loan or initiation of any proceedings, judicial or otherwise, under the related
Mortgage Loan documents;


 


(iv)          any
sale of a Defaulted Loan and any related defaulted Companion Loan, or any REO Property (other than in connection with the termination
of the Trust) or a defaulted Non-Serviced Mortgage Loan that the Special Servicer is permitted to sell in accordance with Section
3.16(a)(iii), in each case, for less than the applicable Purchase Price;


 


(v)          any
determination to bring an REO Property into compliance with applicable environmental laws or to otherwise address hazardous material
located at an REO Property;


 


(vi)          any
release of material collateral or any acceptance of substitute or additional collateral for a Mortgage Loan (other than a Non-Serviced
Mortgage Loan) or Serviced Whole Loan or any consent to either of the foregoing, other than if required pursuant to the specific
terms of the related Mortgage Loan documents and for which there is no lender discretion;


 


(vii)          any
waiver of a “due-on-sale” or “due-on-encumbrance” clause with respect to a Mortgage Loan (other than a
Non-Serviced Mortgage Loan) or a Serviced Whole Loan or any consent to such a waiver or consent to a transfer of the Mortgaged
Property or interests in the Mortgagor, other than any such transfer as described under clause (xiii) of the definition of
Master Servicer Decision;


 


(viii)          any
property management company changes with respect to a Mortgage Loan, including, without limitation, approval of the termination
of a manager and appointment of a new property manager, in each case, if the replacement property manager is a Borrower Party
or the Mortgage Loan has an outstanding principal balance greater than or equal to $10,000,000;


 


(ix)          any
franchise changes with respect to a Mortgage Loan for which the lender is required to consent or approve such changes under the
related Mortgage Loan documents;


 


(x)          releases
of any material amounts from any escrow accounts, Reserve Funds or Letters of Credit, in each case, held as performance escrows
or reserves, other than those required pursuant to the specific terms of the related Mortgage Loan


 






     -370-


     


    

 


documents for any Mortgage
Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan and for which there is no lender discretion other than those
that are permitted to be undertaken by the Master Servicer without the consent of the Special Servicer under this Agreement;


 


(xi)          any
acceptance of an assumption agreement or any other agreement permitting a transfer of interests in a Mortgagor or guarantor releasing

other than pursuant to the specific terms of such Mortgage Loan or Serviced Whole Loan and for which there is no lender discretion;


 


(xii)          subject
to the proviso at the end of this definition, any modification, amendment, consent to a modification or waiver of any material
term of any Intercreditor Agreement, co-lender or similar agreement with any mezzanine lender, subordinate debt holder or Pari Passu
Companion Loan Holder related to a Mortgage Loan or Whole Loan, or any action to enforce rights (or decision not to enforce rights)
with respect thereto; provided, however, that any such modification or amendment that would adversely impact the
Master Servicer shall additionally require the consent of the Master Servicer as a condition to its effectiveness;


 


(xiii)          agreeing
to any modification, waiver, consent or amendment of the related Mortgage Loan or Serviced Whole Loan in connection with a defeasance
if such proposed modification, waiver, consent or amendment is with respect to (A) a modification of the type of defeasance
collateral required under the Mortgage Loan or Serviced Whole Loan documents such that defeasance collateral other than direct,
non-callable obligations of the United States would be permitted or (B) a modification that would permit a principal prepayment
instead of defeasance if the applicable Mortgage Loan documents do not otherwise permit such principal prepayment;


 


(xiv)          other
than with respect to a Non-Specially Serviced Loan, any determination of Acceptable Insurance Default; and


 


(xv)          any
consent to incurrence of additional debt by a Mortgagor or mezzanine debt by a direct or indirect parent of a Mortgagor, to the
extent the Mortgagee’s approval is required under the related Mortgage Loan documents;


 


provided that with respect to any Non-Specially Serviced Loan, if the Special Servicer determines, with respect to clause (xii) above,
that a modification, amendment or waiver is administrative in nature, including a note splitting amendment, the Special Servicer
shall provide written notice of such determination to the Master Servicer, in which case, the Master Servicer will process such
decision and such decision will be deemed to be a Master Servicer Decision not a Major Decision (provided, further,
that the Special Servicer shall make any such determination and provide any such notice within two (2) business days of its receipt
of a request related to any such decision); provided, however, that, in the event that the Special Servicer or the
Master Servicer, as the case may be, determines that immediate action, with respect to the foregoing matters, or any other matter
requiring consent of the Directing Certificateholder prior to the occurrence and continuance of a Control Termination Event in
this Agreement (or any


 






     -371-


     


    

 


matter requiring consultation with the Directing Certificateholder, the Risk Retention Consultation Party
or the Operating Advisor), is necessary to protect the interests of the Certificateholders (or, with respect to any Serviced Whole
Loan, the interest of the Certificateholders and the holders of any related Serviced Companion Loan) (as a collective whole (taking
into account the subordinate or pari passu nature of any Companion Loans)), the Special Servicer or the Master Servicer,
as the case may be, may take any such action without waiting for the Directing Certificateholder’s response (or without
waiting to consult with the Directing Certificateholder, the Risk Retention Consultation Party or the Operating Advisor, as the
case may be); provided that the Special Servicer or the Master Servicer, as the case may be, provides the Directing Certificateholder
(or the Operating Advisor, if applicable) and the Risk Retention Consultation Party with prompt written notice following such
action including a reasonably detailed explanation of the basis therefor. Neither the Master Servicer nor the Special Servicer
is required to obtain the consent of the Directing Certificateholder for any of the foregoing actions or any other matter requiring
consent of the Directing Certificateholder after the occurrence and during the continuance of a Control Termination Event; provided,
however, that, after the occurrence and during the continuance of a Control Termination Event, the Special Servicer shall
consult with the Directing Certificateholder (only prior to the occurrence and continuance of a Consultation Termination Event)
in connection with any Major Decision not relating to an Excluded Loan with respect to the Directing Certificateholder (and any
other actions which otherwise require consultation with the Directing Certificateholder prior to the occurrence and continuance
of a Consultation Termination Event hereunder) and consider alternative actions recommended by the Directing Certificateholder
in respect thereof. Additionally, upon request, the Special Servicer shall consult with the Risk Retention Consultation Party
on a non-binding basis ((i) prior to the occurrence and continuance of a Consultation Termination Event, only with respect to
a Specially Serviced Loan and (ii) after the occurrence and during the continuance of a Consultation Termination Event, with respect
to any Mortgage Loan) in connection with any Major Decision not relating to an Excluded Loan with respect to the Risk Retention
Consultation Party and consider alternative actions recommended by the Risk Retention Consultation Party, in respect thereof.
In the event the Special Servicer receives no response from the Directing Certificateholder 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 Certificateholder or the Risk Retention Consultation Party, as applicable, on the
specific matter; provided, however, that the failure of the Directing Certificateholder or the Risk Retention
Consultation Party to respond shall not relieve the Special Servicer from consulting with the Directing Certificateholder or the
Risk Retention Consultation Party, as applicable, on any future matters with respect to the applicable Mortgage Loan (other than
a Non-Serviced Mortgage Loan or an Excluded Loan with respect to such party) or Serviced Whole Loan. In addition, after a Control
Termination Event, 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 after the occurrence and
during the continuance of a Control Termination Event hereunder) 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 10 Business Days following the later of (i) its written request for
input on any required consultation and (ii) delivery of all such additional information reasonably


 






     -372-


     


    

 


requested by the Operating
Advisor 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 any other Mortgage Loan. Notwithstanding anything herein to the contrary, with
respect to any Excluded Loan with respect to the Directing Certificateholder (regardless of whether a Control Termination 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 this Section 6.08 for consulting with the Operating
Advisor.


 


Subject
to the terms and conditions of this Section 6.08(a), the Special Servicer shall process all requests for any matter that
constitutes a “Major Decision” with respect to all Mortgage Loans (other than any Non-Serviced Mortgage Loan).


 


Upon
receiving a request for any matter that constitutes a Special Servicer Decision or a Major Decision with respect to a Mortgage
Loan (other than any Non-Serviced Mortgage Loan) and any Serviced Companion Loan that is not a Specially Serviced Loan, the Master
Servicer shall promptly forward such request to the Special Servicer and the Special Servicer shall process such request (including,
without limitation, interfacing with the Mortgagor) and except as provided in the next sentence, the Master Servicer shall have
no further obligation with respect to such request or such Special Servicer Decision or Major Decision. With respect to such request,
the Master Servicer shall continue to cooperate with the Special Servicer by delivering any additional information in the Master
Servicer’s possession to the Special Servicer requested by the Special Servicer relating to such Special Servicer Decision
or Major Decision. The Master Servicer shall not be permitted to process any Special Servicer Decision or Major Decision and shall
not be required to interface with the Mortgagor or provide a written recommendation and analysis with respect to any Special Servicer
Decision or Major Decision.


 


With
respect to (i) prior to the occurrence and continuance of a Consultation Termination Event, any Major Decision relating to a Specially
Serviced Loan, and (ii) after the occurrence and during the continuance of a Consultation Termination, any Major Decision relating
to a Mortgage Loan (in each case, other than with respect to an Excluded Loan with respect to the Risk Retention Consultation
Party), the Special Servicer shall provide copies of any notice, information and report that it is required to provide to the
Directing Certificateholder pursuant to this Agreement with respect to such Major Decision to the Risk Retention Consultation
Party, within the same time frame it is required to provide such notice, information or report to the Directing Certificateholder
(for this purpose, without regard to whether such items are actually required to be provided to the Directing Certificateholder
under this Agreement due to the occurrence of a Control Termination Event or a Consultation Termination Event).


 


In
addition, with respect to any Mortgage Loan other than an Excluded Loan with respect to the Directing Certificateholder or the
Holder of the majority of the Controlling Class,


 






     -373-


     


    

 


for so long as no Control Termination Event has occurred and is continuing, the
Directing Certificateholder subject to any rights, if any, of the related Companion Holder to advise the Special Servicer with
respect to the related Serviced Whole Loan, pursuant to the terms of the related Intercreditor Agreement, may direct the Special
Servicer to take, or to refrain from taking, such other actions with respect to a Mortgage Loan, as the Directing Certificateholder
may deem advisable or as to which provision is otherwise made herein; provided that notwithstanding anything herein to
the contrary, no such direction or objection contemplated by the preceding paragraphs of this section or this paragraph, may require
or cause the Master Servicer or Special Servicer to violate any provision of any Mortgage Loan or related Intercreditor Agreement
or mezzanine 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 Directing Certificateholder or the Risk Retention Consultation Party, would cause the Special Servicer
or the 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 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 or the approval of the Risk Retention Consultation Party that does not violate the
terms of any Mortgage 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.


 


With
respect to any matter for which the consent of the Directing Certificateholder is required, to the extent no specific time period
for deemed consent is expressly stated, in the event no response from the Directing Certificateholder is received within ten (10)
Business Days following written request for consent and its receipt of all reasonably requested information on any required consent,
the Directing Certificateholder shall be deemed to have consented to or approved the specific matter; provided that the failure
of the Directing Certificateholder to respond will not affect any future matters with respect to the applicable Mortgage Loan
or Serviced Whole Loan.


 


The
Directing Certificateholder 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 Certificateholder
shall not be protected


 






     -374-


     


    

 


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 Certificateholder may take actions that favor
the interests of one or more Classes of the Certificates including the Holders of the Controlling Class over other Classes of
the Certificates, and that the Directing Certificateholder may have special relationships and interests that conflict with those
of Holders of some Classes of the Certificates, that the Directing Certificateholder may act solely in the interests of the Holders
of the Controlling Class, including the Holders of the Controlling Class, that the Directing Certificateholder does not have any
duties or liability to the Holders of any Class of Certificates other than the Controlling Class, that the Directing Certificateholder
shall not be liable to any Certificateholder, by reason of its having acted solely in the interests of the Holders of the Controlling
Class, and that the Directing Certificateholder shall have no liability whatsoever for having so acted, and no Certificateholder
may take any action whatsoever against the Directing Certificateholder 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 RR Interest 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 RR Interest
or by reason of reckless disregard of obligations or duties owed to the Holders of the RR Interest. By its acceptance of a Certificate,
each Certificateholder acknowledges and agrees 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 RR Interest 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 of the Holders of
an RR Interest, that the Risk Retention Consultation Party does not have any duties or liability to the Holders of any Class of
Certificates other than the RR Interest, that the Risk Retention Consultation Party shall not be liable to any Certificateholder,
by reason of its having acted solely in the interests of the Holder of the RR Interest, and that the Risk Retention Consultation
Party shall have no liability whatsoever for having so acted, 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 issued under the Non-Serviced PSA and/or any Class of Certificates, and that such Non-Serviced
Whole Loan Controlling Holder, with


 






     -375-


     


    

 


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 the related
Non-Serviced PSA, that such Non-Serviced Whole Loan Controlling Holder, shall not be liable to any Certificateholder, by reason
of its having acted solely in the interests of the Holders of the controlling class under the related Non-Serviced PSA, and that
the 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

that if such breach is capable of being cured and the Master Servicer or the Special Servicer, as the case may be, is diligently

(b)          If
any Servicer Termination Event with respect to the Master Servicer or the Special Servicer (in either case, for purposes of this
Section 7.01(b), the “Affected Party”) shall occur and be continuing, then, and in each and every such
case, so long as such Servicer Termination Event shall not have been remedied, the Trustee may, and at the written direction of
the Directing Certificateholder (solely with respect to the Special Servicer and only (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 with respect
to the Directing Certificateholder or the Holder of the majority of the Controlling Class) or the Holders of Certificates entitled
to more than 25% of the Voting Rights, the Trustee shall, terminate (and the Depositor may direct the Trustee to terminate each
of the Master Servicer or the Special Servicer, as the case may be, upon five (5) Business Days’ written notice if there
is a Servicer Termination Event under clause (A) in the parenthetical in Section 7.01(a)(iii) above), by notice
in writing to the Affected Party, with a copy of such notice to the Depositor and the Operating Advisor, all of the rights (subject
to Section 3.11 and Section 6.04) and obligations of the Affected Party under this Agreement and in and to the Mortgage
Loans and the proceeds thereof (other than as a Certificateholder or Companion Holder, if applicable); provided, however,
that the Affected Party shall be entitled to the payment of accrued and unpaid compensation and reimbursement through the date
of such termination as provided for under this Agreement for services rendered and expenses incurred. From and after the receipt
by the Affected Party of such written notice except as otherwise provided in this ARTICLE VII, all authority and power
of the Affected Party under this Agreement, whether with respect to the Certificates (other than as a Holder of any Certificate)
or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee with respect to a termination of the Master Servicer
or the Special Servicer pursuant to and under this Section 7.01, and, without limitation, the Trustee is hereby authorized
and empowered to execute and deliver, on behalf of and at the expense of the Affected Party, as attorney-in-fact or otherwise,
any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans
and related documents, or otherwise. The Master Servicer and the Special Servicer each agree that if it is terminated pursuant
to this Section 7.01(b), it shall promptly (and in any event no later than twenty (20) Business Days subsequent to its
receipt of the notice of termination) provide the Trustee with all documents and records requested by it to enable it to assume
the Master Servicer’s or the Special Servicer’s, as the case may be, functions hereunder, and shall cooperate with
the Trustee in effecting the termination of the Master Servicer’s or the Special Servicer’s, as the case may be, responsibilities
and rights (subject to Section 3.11 and Section 6.04) hereunder,


 






     -379-


     


    

 


including, without limitation, the transfer within
five (5) Business Days to the Trustee for administration by it of all cash amounts which shall at the time be or should have been
credited by the Master Servicer to the Collection Account or any Servicing Account (if it is the Affected Party), by the Special
Servicer to the REO Account (if it is the Affected Party) or thereafter be received with respect to the Mortgage Loans or any
REO Property (provided, however, that the Master Servicer and the Special Servicer each shall, if terminated pursuant
to this Section 7.01(b) or pursuant to Section 7.01(d) (with respect to the Special Servicer), continue to be entitled
to receive all amounts accrued or owing to it under this Agreement on or prior to the date of such termination, whether in respect
of Advances (in the case of the Special Servicer or the Master Servicer) or otherwise, and it and its Affiliates and the directors,
managers, officers, members, employees and agents of it and its Affiliates shall continue to be entitled to the benefits of Section
3.11 and Section 6.04 notwithstanding any such termination).


 


(c)          If
the Master Servicer receives notice of termination under Section 7.01(b) solely due to a Servicer Termination Event under
Section 7.01(a)(viii), (a)(ix) or (a)(x), the Master Servicer shall have a forty-five (45) day period after
such notice in which to find a successor master servicer qualified to act as Master Servicer hereunder in accordance with Section
6.03 and Section 7.02 and to which the Master Servicer can sell its rights to service the Mortgage Loans under this
Agreement. During such forty-five (45) day period the Master Servicer may continue to serve as the 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(b), 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. Any 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 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 applicable 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 as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25).


 


(d)          Subject
to the rights of the holder of a related AB Subordinate Companion Loan pursuant to the related Intercreditor Agreement, at any
time prior to the occurrence and


 






     -380-


     


    

 


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 the 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 Intercreditor
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 appoint 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 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 and any other Form 8-K filings have been completed with
respect to any related Companion Loan. For the sake of clarity, the recommendation of replacement of the Special Servicer by the
Operating Advisor and the approval of the Certificateholders of such Qualified Replacement Special Servicer shall not preclude
the Directing Certificateholder from appointing a replacement special servicer, provided that such replacement may not be the
removed Special Servicer or its Affiliate.


 


After
the occurrence and during the continuance of a Control Termination Event and 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) of the Principal Balance
Certificates requesting a vote to replace the Special Servicer with a new special servicer designated in such written direction
to assume the duties of the Special Servicer hereunder, (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 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) and confirmation from the applicable 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 Pari Passu Companion Loan Securities, 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 (other than the RR Interest) in such regard,


 






     -381-


     


    

 


which requisite affirmative votes shall be received within one hundred-eighty (180) days of the posting of such notice, and if
not so received, such votes shall be null and void ab initio. Upon the written direction of Holders of Certificates
evidencing at least 66-2/3% of a Certificateholder Quorum of Certificates, the Trustee shall terminate all of the rights and obligations
of the Special Servicer under this Agreement and appoint the successor special servicer to assume the duties of the 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 Certificateholder’s direction to remove such Special Servicer shall
not apply to any Serviced AB Whole Loan for which the holder of the related AB Subordinate Companion Loan is not subject to an
AB Control Appraisal Period or to any Servicing Shift Whole Loan.


 


An
AB Whole Loan Controlling Holder shall have the right, prior to the occurrence and continuance of an AB Control Appraisal Period,
to replace the applicable Special Servicer solely with respect to the related Serviced AB Whole Loan, so long as (A) each
Rating Agency delivers a Rating Agency Confirmation; (B) the successor special servicer has assumed in writing (from and
after the date such successor special servicer becomes the Special Servicer) all of the responsibilities, duties and liabilities
of such Special Servicer under this Agreement from and after the date it becomes the applicable Special Servicer as they relate
to any Serviced AB Whole Loan pursuant to an assumption agreement reasonably satisfactory to the Trustee; and (C) the Trustee
shall have received an opinion of counsel reasonably satisfactory to the Trustee to the effect that (x) the designation of
such replacement to serve as Special Servicer is in compliance with this Agreement, (y) such replacement will be bound by
the terms of this Agreement with respect to any Serviced AB Whole Loan and (z) subject to customary qualifications and exceptions,
this Agreement will be enforceable against such replacement in accordance with the terms hereof.


 


The
Servicing Shift Lead Note holder shall have the right, to the extent provided under the related Intercreditor Agreement, to replace
the Special Servicer solely with respect to the Servicing Shift Whole Loan, as applicable, so long as: (A) each Rating Agency
delivers a Rating Agency Confirmation; (B) the successor special servicer has assumed in writing (from and after the date such
successor special servicer becomes the Special Servicer) all of the responsibilities, duties and liabilities of the Special Servicer
under this Agreement from and after the date it becomes the Special Servicer as they relate to the Servicing Shift Whole Loan,
pursuant to an assumption agreement reasonably satisfactory to the Trustee; and (C) the Trustee shall have received an opinion
of counsel reasonably satisfactory to the Trustee to the effect that (x) the designation of such replacement to serve as Special
Servicer is in compliance with this Agreement, (y) such replacement will be bound by the terms of this Agreement with respect
to the Servicing Shift Whole Loan, and (z) subject to customary qualifications and exceptions, this Agreement will be enforceable
against such replacement in accordance with the terms hereof.


 


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


 






     -382-


     


    

 


related Non-Serviced Special Servicer
has not otherwise been terminated, the holder of the related Non-Serviced Mortgage Loan (or 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 the applicable
Non-Serviced Special Servicer with respect to a Non-Serviced Whole Loan 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 consultation
termination event 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.


 


Following
the occurrence and continuance of a Control Termination Event, subject to the immediately succeeding paragraph, if the Operating
Advisor determines, in its sole discretion exercised in good faith, that the Special Servicer is not performing its duties as
required hereunder or is otherwise not acting in accordance with the Servicing Standard, 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, setting forth the reasons supporting its recommendation (along with any information the Operating Advisor
considered relevant to its recommendation) and recommending a replacement Special Servicer (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 recommendation contravene any provision of this Agreement) detailing the reasons supporting
its recommendation (along with relevant information justifying its recommendation) and recommending a suggested replacement special
servicer to assume the duties of the Special Servicer, which shall be a Qualified Replacement Special Servicer. In such event,
the Certificate Administrator shall promptly post notice to all Certificateholders of such recommendation and the related report
on the Certificate Administrator’s Website in accordance with Section 3.13(b), and concurrently by mail conduct the
solicitation of votes of all Certificates in such regard. Upon (i) the affirmative vote of Holders of Principal Balance Certificates
evidencing at least a majority of the aggregate Voting Rights (taking into account the application of any Appraisal Reduction
Amounts to notionally reduce the respective Certificate Balances of such Certificates) of all Principal Balance Certificates on
an aggregate basis within 180 days of posting of the Operating Advisor’s recommendation to the Certificate Administrator’s
Website, and if not so received, such votes shall be null and void ab initio, and (ii) receipt by the Certificate
Administrator following satisfaction of the foregoing clause (i) of Rating Agency Confirmation from each Rating Agency
and confirmation from the applicable 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 Pari Passu Companion Loan Securities,
the Trustee shall (i) terminate all of the rights and obligations of the Special Servicer under this Agreement and appoint
a successor special servicer approved by the Certificateholders 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


 






     -383-


     


    

 


counsel) associated with obtaining such Rating Agency Confirmations and administering such vote 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 at least a majority of the required votes, 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.
Notwithstanding the foregoing, the Operating Advisor shall not be permitted to recommend the replacement of a Special Servicer
with respect to an AB Whole Loan so long as the related Serviced Companion Noteholder is not subject to an AB Control Appraisal
Period under the related Intercreditor Agreement or with respect to any Servicing Shift Whole Loan.


 


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 Certificateholders
(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 with respect to the Master
Servicer or Special Servicer, as applicable. In no event shall the remedy for a breach of the foregoing covenant extend beyond
termination pursuant to Section 7.01(a)(ix) and the resulting operation of Section 7.01(b) and (c). The operation
of this subsection (e) shall not be construed to limit the effect of 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,
the related holder of a Serviced Companion Loan or the rating on 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, the related holder of a Serviced Companion Loan or the rating on any Serviced Companion Loan Securities, then
the Master Servicer may not be terminated by or at the direction of the related holder of such Serviced Companion Loan or the
holders of any Serviced Companion Loan Securities, but upon the written direction of the related holder of such Serviced Companion
Loan, 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


 






     -384-


     


    

 


continuance of a Control Termination Event, if the applicable Excluded Special Servicer Loan is not also an Excluded Loan with
respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder
shall 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, if at
any time the applicable Excluded Special Servicer Loan is also an Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class, the resigning Special Servicer shall select the related Excluded Special
Servicer. The resigning 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. 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 that had previously acted as the Special Servicer is no longer a Borrower Party with respect
to an Excluded Special Servicer Loan (including, without limitation, as a result of the related Mortgaged Property becoming REO
Property), (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) such original Special Servicer shall become the Special Servicer
again for such related Mortgage Loan or Serviced Whole Loan and (4) such original 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.


 


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.


 


If
a Servicing Officer of the Master Servicer, a related Excluded Special Servicer, or the Special Servicer, as the case may be,
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 the case
may be, 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 clause (a) of Section 6.05 or receives
a notice of termination for cause pursuant to Section 7.01(b), and


 






     -385-


     


    

 


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 that Master Servicer or that Special Servicer, as applicable, is appointed as provided in this Section
7.02 or by the Directing Certificateholder as provided in Section 7.01(d), as applicable, in all respects in its
capacity as the 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 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 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 or the Companion Loans which that 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 that Master Servicer or that 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 Certificateholder
(solely with respect to the Special Servicer) ((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 Certificateholder or the Holder of the
majority of the Controlling Class) or the Holders of Certificates entitled to more than 50% of the Voting Rights so request
in writing to the Trustee, promptly appoint, or petition a court of competent jurisdiction to appoint, any established
mortgage loan servicing institution which meets the criteria set forth in Section 6.05 and otherwise herein, as the
successor to that Master Servicer or that Special Servicer, as applicable, hereunder in the assumption of all or any part of
the responsibilities, duties or liabilities of the


 






     -386-


     


    

 


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) 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) such appointment (solely with respect to the
Special Servicer) has been approved (prior to the occurrence and continuance of a Control Termination Event and other than
with respect to an Excluded Loan) by the Directing Certificateholder, 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 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 non-terminated Master Servicer or the non-terminated Special Servicer and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such succession. Any reasonable out-of-pocket 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 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 the
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


 






     -387-


     


    

 


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. The Holders of Certificates representing at
least 66-2/3% of the Voting Rights allocated to each Class of Certificates affected by any Servicer Termination Event
hereunder may waive such Servicer Termination Event; provided, however, that a Servicer Termination Event under clause (i), (ii)
or (viii) of Section 7.01(a) may be waived only with the consent of all of the Certificateholders of the
affected Classes, and a Servicer Termination Event under clause (iii) of Section 7.01(a) (with respect to
obligations under ARTICLE XI) may be waived only with the consent of the Depositor. Upon any such waiver of a
Servicer Termination Event, subject to the rights of any affected holder of a Serviced Companion Loan under Section
7.01(c) or Section 7.01(f), 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) 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 the Master
Servicer’s default in its


 






     -388-


     


    

 


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.

are specifically set forth in this Agreement. If a Servicer Termination Event occurs and is continuing, the Trustee shall
exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their

of this Agreement in a material manner, the Trustee or the Certificate Administrator shall notify the party providing such instrument
and requesting the correction thereof. The Trustee or the Certificate Administrator shall not be responsible for 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 or another Person, and accepted by the Trustee or the Certificate Administrator in
good faith, pursuant to this Agreement.


 


(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

such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read
into this Agreement against the Trustee and the Certificate Administrator and, in the absence of bad faith on the part of the
Trustee and the Certificate Administrator, the Trustee and the Certificate Administrator may conclusively rely, as to the truth
of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee
or the Certificate Administrator and conforming to the requirements of this Agreement;


 


(ii)          Neither
the Trustee nor the Certificate Administrator, as applicable, shall be liable for an error of judgment made in good faith by a
Responsible Officer or Responsible Officers of the Trustee or the Certificate Administrator, respectively, unless it shall be
proved that the Trustee or the Certificate Administrator, as applicable, was negligent in ascertaining the pertinent facts; and


 


(iii)          Neither
the Trustee nor the Certificate Administrator, as applicable, shall be liable with respect to any action taken, suffered or omitted
to be taken by it in good faith in accordance with the direction of Holders of Certificates entitled to greater than 25% (i) of
the Percentage Interest of each affected Class, or (ii) if each Class is an affected Class of the aggregate Voting Rights
of the Certificates, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee
or the Certificate Administrator, or exercising any trust or power conferred upon the Trustee or the Certificate Administrator,
under this Agreement (unless a higher percentage of Voting Rights is required for such action).


 


(d)          The
Certificate Administrator shall make available via its internet website initially located at www.ctslink.com to the Serviced Companion
Noteholders all reports that the Certificate Administrator has made available to Certificateholders under this Agreement to the
extent such reports relate to the related Serviced Companion Loan and upon the submission of an Investor Certification pursuant

Section
8.02     Certain Matters Affecting the Trustee and the Certificate Administrator. Except as
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,

     -390-


     


    

 


(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, security or indemnity reasonably 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, unless repayment of such funds or indemnity reasonably satisfactory to it against such risk or liability is 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;

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 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 indemnity reasonably 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
shall not relieve the Trustee or the Certificate Administrator of its duties or obligations hereunder; provided, further,
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;


 






     -391-


     


    

 


(vii)    For
all purposes under this Agreement, none of the Trustee, the Custodian or 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 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 any event, act, failure or breach, as applicable, which is in fact such a default is received by the Trustee or the
Certificate Administrator at the respective Corporate Trust Office, and such notice references the Certificates or this Agreement;


 


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


 


(xii)     Nothing
herein shall be construed as an obligation for any party to this Agreement to advise a Certificateholder with respect to its rights
and protections relative to the Trust.

Section
8.03     Trustee and Certificate Administrator Not Liable for Validity or Sufficiency of Certificates
or Mortgage Loans. The recitals contained herein and in the Certificates, other than the acknowledgments of the Trustee
or the Certificate Administrator in Sections  2.01(h) and Section 2.04 and the signature, if any, of the Certificate
Registrar and Authenticating Agent set forth on any outstanding Certificate, shall not be taken as the statements of the Trustee
or the Certificate Administrator, and the Trustee or the Certificate Administrator assume no responsibility for their correctness.
Neither the Trustee nor the


 






     -392-


     


    

 


Certificate
Administrator makes any representations as to the validity or sufficiency of this Agreement 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 related
document. Neither the Trustee nor the Certificate Administrator shall be accountable for the use or 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 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
8.04     Trustee or Certificate Administrator May Own Certificates. The
Trustee or the Certificate Administrator, each in its individual capacity, not as Trustee or Certificate Administrator, may become
the owner or pledgee of Certificates, and may deal with the Depositor, the Master Servicer, the Special Servicer or the Underwriters
in banking 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 their respective duties hereunder, the Trustee will be paid the Trustee Fee, which shall cover
recurring and otherwise reasonably anticipated expenses of the Trustee, and the Certificate Administrator will be paid the Certificate
Administrator Fee equal to the Certificate Administrator’s portion of one (1) month’s interest at the Certificate
Administrator Fee Rate, which shall cover recurring and otherwise reasonably anticipated expenses of the Certificate Administrator.
The Trustee Fee and Certificate Administrator Fee shall be paid monthly on a Mortgage Loan-by-Mortgage Loan basis. As to each
Mortgage Loan and REO Loan (other than the portion of an REO Loan related to any Companion Loan), the Certificate Administrator
shall pay to the Trustee monthly the Trustee Fee from the Certificate Administrator Fee, which Certificate Administrator Fee shall
accrue from time to time at the Certificate Administrator Fee Rate and the Certificate Administrator Fee shall be computed in
the same manner as interest is calculated thereon and for the same period respecting which any related interest payment due or
deemed thereon is computed. The 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 sole form of compensation for all services rendered by
it in the execution of the trusts hereby created and in the exercise and performance of any of the powers and duties of the Trustee
hereunder, except for the reimbursement of expenses specifically provided for herein. The Certificate Administrator Fee shall
constitute the Certificate Administrator’s sole form of compensation for the exercise and performance of its powers and
duties hereunder, except for the reimbursement of expenses specifically provided for herein. No Trustee Fee or Certificate Administrator
Fee shall be payable with respect to any Companion Loan.


 


(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,


 






     -393-


     


    

 


representative or agent of the Trustee and the Certificate Administrator, respectively, shall
be entitled to be indemnified and held harmless by the Trust (to the extent of amounts on deposit in the Collection Account or
the Lower-Tier REMIC Distribution Account, as applicable, from time to time) against any loss, liability or expense (including,
without limitation, costs and expenses of litigation, 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 Information Provider) hereunder; provided, however,
that none of the Trustee or the Certificate Administrator, nor 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, 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.


 


For
the avoidance of doubt, with respect to any indemnification provisions in this Agreement providing that the Issuing Entity or
any other party to this Agreement is required to indemnify another party to this Agreement for costs, fees and expenses, such
costs, fees and expenses are intended to include costs (including, but not limited to, reasonable attorney’s fees and expenses)
of the enforcement of such indemnity.


 


(c)       The
Certificate Administrator shall indemnify and hold harmless the Depositor and the 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 or 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


 






     -394-


     


    

 


an NRSRO, in the performance of such obligations or its negligent disregard of its obligations
and duties under this Agreement.

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, “A2”
by Moody’s, “A-” by Fitch and, if rated by KBRA, “A” by KBRA; provided that the Trustee will
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 “Baa2” by Moody’s, (b) its short-term debt obligations have a short-term
rating of not less than “P-2” from Moody’s and “F1” by Fitch and “A-2” by S&P and
(c) the Master Servicer maintains a long-term unsecured rating of at least “A2” by Moody’s and “A+”
by Fitch; provided that nothing in this clause (c) shall impose on the Master Servicer any obligation to maintain
such rating; provided, further, that if any such institution is not rated by KBRA, such institution maintains an
equivalent (or higher) rating by any two other NRSROs (which may include Moody’s and/or Fitch) or such other rating with
respect to which the Rating Agencies have provided a Rating Agency Confirmation and (iv) an entity that is not a Prohibited
Party.


 


If
such corporation, national bank or national banking association publishes reports of condition at least annually, pursuant to
law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.06
the combined capital and 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 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), 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 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 Operating Advisor, the Asset Representations Reviewer, 17g-5 Information Provider and to all Certificateholders.
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


 






     -395-


     


    

 


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 Certificateholder 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. 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 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, and such petition will be an expense of the Trust.


 


(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 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 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 requesting 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. 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 75% 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


 






     -396-


     


    

 


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 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 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 trustee, in each instance meeting the eligibility requirements set forth hereunder.


 


Upon
any succession of the Trustee or Certificate Administrator under this Agreement, the predecessor Trustee or Certificate Administrator
shall be entitled to the payment of accrued and unpaid compensation and reimbursement as provided for under this Agreement for
services rendered and expenses incurred (including without limitation, unreimbursed Advances). No Trustee or Certificate Administrator
shall be personally liable for any action or omission of any successor trustee or certificate administrator.


 


(e)       Upon
the resignation, assignment, merger, consolidation, or transfer of the Trustee or its business to a successor, or upon the termination
of the Trustee, (a) the outgoing Trustee shall (i) endorse the original executed Mortgage Note for each Mortgage Loan
(to the extent that the original executed Mortgage Note for each Mortgage Loan was endorsed to the outgoing trustee), without
recourse, representation or warranty, express or implied, to the order of the successor, as trustee for the registered Holders
of UBS Commercial Mortgage Trust 2017-C4, Commercial Mortgage Pass-Through Certificates, Series 2017-C4 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 certify in writing that, as to each Mortgage Loan then subject
to this Agreement, such endorsement and assignment has been made; (b) if any original executed Mortgage Note for a Mortgage
Loan was not endorsed to the outgoing trustee, the Custodian shall, upon its receipt of a Request for Release, deliver such Mortgage
Note 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 Note is endorsed (without recourse, representation or warranty, express or implied)
to the order of the successor, as trustee for the registered Holders of UBS Commercial Mortgage Trust 2017-C4, Commercial Mortgage
Pass-Through Certificates, Series 2017-C4 or in blank; provided, however, that, notwithstanding anything to the
contrary herein, to the extent any such endorsement of such Mortgage Note


 






     -397-


     


    

 


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 document was not assigned to the outgoing
trustee, the Custodian shall, upon its receipt of a Request for Release, deliver such Mortgage 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 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 certify in writing that,
as to each Mortgage Loan 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.


 


(f)       Neither
the Asset Representations Reviewer nor any of its Affiliates may be appointed as successor trustee or 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 the 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

acceptance of appointment by a successor trustee or successor certificate administrator as provided in this Section 8.08,

certificate administrator shall cause such notice to be delivered at the expense of the Master Servicer.


 


Section

conversion or consolidation to which the Trustee or the Certificate Administrator shall be a party, or any Person succeeding to
all or substantially all of the corporate trust business of the Trustee or the Certificate Administrator shall 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 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 Website in accordance with Section 3.13(c).


 


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 part of the Trust
Fund, and to vest in such Person or Persons, in such capacity, such title to the Trust, or any part thereof, 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


 






     -399-


     


    

 


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 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 other than the initial 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.

8.12     Representations and Warranties of the Trustee. The Trustee hereby represents and
warrants to the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,

and the rights of creditors of national banking associations specifically and (b) general principles of equity, regardless
of whether such enforcement is considered in a proceeding in equity or at law;

Trustee is not in violation of, and its execution and delivery of this Agreement and its performance and compliance with the terms
of this Agreement will not constitute a violation of, any law, any order or decree of any court or arbiter, or any order, regulation

and reasonable judgment, is likely to affect materially and adversely the ability of the Trustee to perform its obligations under
this Agreement;

by this Agreement, except for any consent, approval, authorization or order which has not been obtained or cannot be obtained
prior to the actual performance by the Trustee of its obligations under this Agreement, and which, if not obtained would not have
a materially adverse effect on the ability of the Trustee to perform its obligations hereunder.

8.13     Provision of Information to Certificate Administrator, Master Servicer and Special Servicer. The
Master Servicer shall promptly, upon request, provide the Special Servicer and the Certificate Administrator with notice of any

Serviced Companion Noteholders to the extent updated or correct information regarding the holders of any of the Serviced Companion

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, shall
deposit in the Collection Account an amount in immediately available funds equal to all amounts due and owing to the Depositor,
the Master 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. 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 3.04(b) (provided, however,
that if a Serviced Whole Loan is secured by


 






     -404-


     


    

 


REO Property, the portion of the above-described purchase price allocable to such
Trust’s portion of REO Property shall initially be deposited into the related REO Account). Upon confirmation that such
final deposits have been made and following the surrender of all its Certificates (other than the Class Z 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 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 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
Holder 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) 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 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 Balances of the Mortgage 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 as set forth in the Preliminary Statement. This purchase shall terminate
the Trust and retire the then-outstanding Certificates. In the event that the Master Servicer or the Special Servicer purchases,
or the Holder of the majority of the Controlling Class or the Holders of the Class R Certificates purchase, all of the Mortgage
Loans and the Trust’s portion of each REO Property remaining in the Trust Fund in accordance with the preceding sentence,
the Master Servicer, the Special Servicer, the Holder of the majority of the Controlling Class or the Holders of the Class R
Certificates, as the case may be, shall deposit in the Lower-Tier REMIC Distribution Account not later than the P&I Advance
Date relating to the Distribution Date on which the final distribution on the Certificates is to occur, an amount in immediately
available funds equal to the above-described purchase price (exclusive of any portion thereof payable to any Person other than
the Certificateholders pursuant to Section 3.05(a), which portion shall be deposited in the Collection Account). In addition,
the Master


 






     -405-


     


    

 


Servicer shall transfer to the Lower-Tier REMIC Distribution Account all amounts required to be transferred thereto
on such P&I Advance Date from the Collection Account pursuant to the first paragraph of Section 3.04(b), together with
any other amounts on deposit in the Collection Account that would otherwise be held for future distribution. Upon confirmation
that such final deposits and payments have been made, the Custodian shall release or cause to be released to the Master Servicer,
the Special Servicer, the Holder of the majority of the Controlling Class or the Holders of the Class R Certificates, as
applicable, the Mortgage Files for the remaining Mortgage Loans and shall execute all assignments, endorsements and other instruments
furnished to it by the Master Servicer, the Special Servicer, the Holder of the majority of the Controlling Class or the Holders
of the Class R Certificates, as the case may be, as shall be necessary to effectuate transfer of the Mortgage Loans as assets
of the Trust and REO Properties remaining in the Trust Fund.


 


For
purposes of this Section 9.01, the Holder of the majority of the Controlling Class shall have the first option to terminate
the Upper-Tier REMIC and Lower-Tier REMIC, then the Special Servicer, then the Master Servicer and then the Holders of the Class R
Certificates. For purposes of this Section 9.01, the Directing Certificateholder with the consent of the Holders of the
Controlling Class, shall act on behalf of the Holders of the Controlling Class in purchasing the assets of the Trust and terminating
the Trust.


 


Notice
of any termination pursuant to this Section 9.01 shall be given promptly by the Certificate Administrator by letter to
the Certificateholders, each Serviced Companion Noteholder and the 17g-5 Information Provider in accordance with the provisions
of Section 3.13(c) (who shall promptly post a copy of such additional notice on the 17g-5 Information Provider’s
Website in accordance with the provisions of Section 3.13(c)) and, if not previously notified pursuant to this Section
9.01, to the other parties hereto mailed (a) in the event such notice is given in connection with the purchase of all
of the Mortgage Loans is an asset of the Trust) and each REO Property remaining in the Trust Fund, not earlier than the fifteenth
(15th) day and not later than the twenty-fifth (25th) day of the month next preceding the month of the final distribution on the
Certificates, or (b) otherwise during the month of such final distribution on or before the P&I Advance Determination
Date in such month, in each case specifying (i) the Distribution Date upon which the Trust will terminate and final payment
of the Certificates will be made, (ii) the amount of any such final payment and (iii) that the Record Date otherwise
applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates
at the offices of the Certificate Registrar or such other location therein designated.


 


After
transferring the Lower-Tier Distribution Amount and the amount of any Prepayment Premiums and Yield Maintenance Charges distributable
to the Regular Certificates pursuant to Section 4.01(e) to the Upper-Tier REMIC Distribution Account, in each case pursuant
to Section 3.04(b) and upon presentation and surrender of the Certificates by the Certificateholders on the final Distribution
Date, the Certificate Administrator shall distribute to each Certificateholder so presenting and surrendering its Certificates
(i) such Certificateholder’s Percentage Interest of that portion of the amounts then on deposit in the Upper-Tier REMIC
Distribution Account that are allocable to payments on the Class of Certificates so presented, (ii) to Holders of the Excess
Interest Certificates so presented, any amounts remaining on deposit in the Excess Interest Distribution Account, and (iii) any
remaining amount shall be distributed


 






     -406-


     


    

 


to the Class R Certificates in respect of the Class LR Interest or the Class UR
Interest, as applicable. Amounts transferred from the Lower-Tier REMIC Distribution Account to the Upper-Tier REMIC Distribution
Account as of the final Distribution Date, shall be distributed in termination and liquidation of the Lower-Tier Regular Interests
and the Class LR Interest in accordance with Sections 4.01(a), 4.01(c), 4.01(e) and 4.01(f).
Any funds not distributed on such Distribution Date shall be set aside and held uninvested in trust for the benefit of the Certificateholders
not presenting and surrendering their Certificates in the aforesaid manner and shall be disposed of in accordance with this Section
9.01 and Section 4.01(h).


 


Section
9.02     Additional Termination Requirements. (a)  In the event the Master Servicer
or the Special Servicer purchases, or the Holders of the Controlling Class or the Holders of the Class R Certificates purchase,
all of the Mortgage Loans and the Trust’s portion of each REO Property remaining in the Trust Fund as provided in Section
9.01, the Upper-Tier REMIC and Lower-Tier REMIC, as applicable, shall be terminated in accordance with the following additional
requirements, which meet the definition of a “qualified liquidation” in Section 860F(a)(4) of the Code:


 


(i)       the
Certificate Administrator shall specify the date of adoption of the plan of complete liquidation (which shall be the date of mailing
of the notice specified in Section 9.01) in a statement attached to each of the related Trust REMICs’ final Tax Returns
pursuant to Treasury Regulations Section 1.860F-1;


 


(ii)      during
the 90-day liquidation period and at or prior to the time of the making of the final payment on the Certificates, the Certificate

Servicer, the Holders of the Controlling Class or the Holders of the Class R Certificates, as applicable, for cash; and


 


(iii)      within
such 90-day liquidation period and immediately following the making of the final payment on the Lower-Tier Regular Interests and
the Certificates, the Certificate Administrator shall distribute or credit, or cause to be distributed or credited, to the Holders
of the Class R Certificates in respect of the Class LR Interest (in the case of the Lower-Tier REMIC) and in respect
of the Class UR Interest (in the case of the Upper-Tier REMIC) all cash on hand (other than cash retained to meet claims),
and the Trust (if applicable) or the related Trust REMIC(s) shall terminate at that time.

ADDITIONAL REMIC PROVISIONS


 


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 and the Certificates are


 






     -407-


     


    

 


issued. For the
purposes of the REMIC election in respect of the Upper-Tier REMIC, each Class of the Regular Certificates shall be designated
the “regular interests,” and the Class UR Interest shall be designated the sole class of “residual interests”
in the Upper-Tier REMIC. For purposes of the REMIC election in respect of the Lower-Tier REMIC, each Class of 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” (“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
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. The Holder
of the largest Percentage Interest in 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 applicable to the Trust REMICs) of each Trust REMIC. By their acceptance thereof, the Holder of the largest Percentage Interest
in the Class R Certificates hereby agrees to irrevocably appoint the Certificate Administrator as its 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,
Form 8811, within thirty (30) days after the Closing Date, the name, title, address and telephone number of the “tax
matters person” who will serve as the representative of each of the Trust


 






     -408-


     


    

 


REMICs created hereunder. The Certificate Administrator
shall prepare, and the Trustee shall sign, the Form 8811.


 


(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, cause the loss of 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 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


 






     -409-


     


    

 


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, (x) 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 (y) 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) 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
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 of their respective obligations under this Agreement which breach
constitutes willful misconduct, bad faith, or negligence by such 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.


 


(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 the Certificate Balance or Notional Amount of each Class of Regular Certificates and by which the Lower-Tier Principal Amount
of each Class of Lower-Tier Regular Interests would be reduced to zero is the date that is the Rated Final Distribution Date.


 






     -410-


     


    

 


(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 (except in connection with (i) the default, imminent default or foreclosure
of a Mortgage 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 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 the case may be, 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 allowed under the Code (i) to avoid the application of Section 6221 of the Code
(or successor provisions) to either Trust REMIC and (ii) to avoid payment by either Trust REMIC under Section 6225 of the
Code (or successor provisions) of any tax, penalty, interest or other amount imposed under the Code that would otherwise be imposed
on any Holder of a Class R Certificate, past or present. Each Holder of a Class R Certificate agrees, by acquiring such Certificate,
to any such elections.


 


Section
10.02     Use of Agents. (a)  The Trustee shall execute all of its obligations and
duties under this ARTICLE X through its Corporate Trust Office. The Trustee may execute any of its obligations and
duties under this ARTICLE X either directly or by or through agents or attorneys. The Trustee shall not be relieved of
any of its duties or obligations under this ARTICLE X by virtue of the appointment of any such agents or
attorneys.


 


(b)          The
Certificate Administrator may execute any of its obligations and duties under this ARTICLE X either directly or by or through
agents or attorneys. The Certificate Administrator shall not be relieved of any of its duties or obligations under this ARTICLE
X by virtue of the appointment of any such agents or attorneys.


 


Section
10.03     Depositor, Master Servicer and Special Servicer to Cooperate with Certificate
Administrator. (a)  The
Depositor shall provide or cause to be provided to the Certificate Administrator within ten (10) days after the Depositor
receives a request from the Certificate Administrator, all information or data that the Certificate Administrator reasonably
determines to be relevant for tax purposes as to the valuations and issue prices of the Certificates, including, without
limitation, the price, yield, Prepayment Assumptions and projected cash flow of the Certificates.


 


(b)          The
Master Servicer and the Special Servicer shall each furnish such reports, certifications and information, and upon reasonable
notice and during normal business hours, access to such books and records maintained thereby, as may relate to the Certificates
or


 






     -411-


     


    

 


the
Trust and as shall be reasonably requested by the Certificate Administrator in order to enable it to perform its duties hereunder.


 


Section
10.04     Appointment of REMIC Administrators. (a)  The Certificate Administrator
may appoint at the Certificate Administrator’s expense, one or more REMIC Administrators, which shall be authorized to
act on behalf of the Certificate Administrator in performing the functions set forth in Section 10.01 herein. The
Certificate Administrator shall cause any such REMIC Administrator to execute and deliver to the Certificate Administrator an
instrument in which REMIC Administrator shall agree to act in such capacity, with the obligations and responsibilities
herein. The appointment of a REMIC Administrator shall not relieve the Certificate Administrator from any of its obligations
hereunder, and the Certificate Administrator shall remain responsible and liable for all acts and omissions of the REMIC
Administrator. Each REMIC Administrator must be acceptable to the Certificate Administrator and must be organized and doing
business under the laws of the United States of America or of any State and be subject to supervision or examination by
federal or state authorities. In the absence of any other Person appointed in accordance herewith acting as REMIC
Administrator, the Certificate Administrator hereby agrees to act in such capacity in accordance with the terms hereof. If
Wells Fargo Bank, National Association is removed as Certificate Administrator, then Wells Fargo Bank, National Association
shall be terminated as REMIC Administrator.


 


(b)          Any
Person into which any REMIC Administrator may be merged or converted or with which it may be consolidated, or any Person resulting
from any merger, conversion, or consolidation to which any REMIC Administrator shall be a party, or any Person succeeding to the
corporate agency business of any REMIC Administrator, shall continue to be the REMIC Administrator without the execution or filing
of any paper or any further act on the part of the Certificate Administrator or the REMIC Administrator.


 


(c)          Any
REMIC Administrator may at any time resign by giving at least thirty (30) days’ advance written notice of resignation to
the Trustee, the Certificate Registrar, the Certificate Administrator, the Master Servicer, the Special Servicer and the Depositor.
The Certificate Administrator may at any time terminate the agency of any REMIC Administrator by giving written notice of termination

of this Section 10.04, the Certificate Administrator may appoint a successor REMIC Administrator, in which case the Certificate
Administrator shall give written notice of such appointment to the Master Servicer, the Trustee and the Depositor and shall mail
notice of such appointment to all Certificateholders; provided, however, that no successor REMIC Administrator shall
be appointed unless eligible under the provisions of this Section 10.04. Any successor REMIC Administrator upon acceptance
of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder,
with like effect as if originally named as REMIC Administrator. No REMIC Administrator shall have responsibility or liability
for any action taken by it as such at the direction of the Certificate Administrator.

EXCHANGE ACT REPORTING AND REGULATION AB COMPLIANCE


 


Section
11.01     Intent of the Parties; Reasonableness. The parties hereto acknowledge and agree
that the purpose of ARTICLE XI of this Agreement is to facilitate compliance by the Depositor (and any Other Depositor
of any Other Securitization that includes a Serviced Companion Loan) with the provisions of Regulation AB and the
related rules and regulations of the Commission. The Depositor shall not exercise its rights to request delivery of
information or other performance under these provisions other than in reasonable good faith, or for purposes other than
compliance with the Securities Act, the Exchange Act, the Sarbanes-Oxley Act and, in each case, the rules and regulations of
the Commission thereunder. The parties hereto acknowledge that interpretations of the requirements of Regulation AB may
change over time, due to interpretive guidance provided by the Commission or its staff, and agree to comply with requests
made by the Depositor (or any Other Depositor or Other Trustee of any Other Securitization that includes a Serviced Companion
Loan) in good faith for delivery of information under these provisions on the basis of such evolving interpretations of
Regulation AB (to the extent such interpretations require compliance and are not “grandfathered”). In
connection with the UBS Commercial Mortgage Trust 2017-C4, Commercial Mortgage Pass-Through Certificates, Series 2017-C4, and
any Other Securitization subject to Regulation AB that includes a Serviced Companion Loan, each of the Master Servicer, the
Special Servicer, the Operating Advisor, the Trustee, the Custodian and the Certificate Administrator shall cooperate fully
with the Depositor and the Certificate Administrator, and any Other Depositor, Other Trustee and Other
Certificate Administrator of any Other Securitization that includes a Serviced Companion Loan, as applicable, to deliver or
make available to the Depositor or the Certificate Administrator, and any such Other Depositor, Other Trustee or Other
Certificate Administrator, as applicable (including any of its assignees or designees), any and all statements, reports,
certifications, records and any other information (in its possession or reasonably attainable) necessary in the reasonable
good faith determination of the Depositor or such Other Depositor, as applicable, to permit the Depositor or such Other
Depositor, as applicable, to comply with the provisions of Regulation AB, together with such disclosures relating to the
Master Servicer, the Special Servicer, the Operating Advisor, the Trustee, the Custodian, the Asset Representations Reviewer
and the Certificate Administrator, as applicable, and any Sub-Servicer, or the servicing of the Mortgage Loans (and the
related Serviced Companion Loan, if applicable), reasonably believed by the Depositor or the related Other Depositor to be
necessary in order to effect such compliance. Each party to this Agreement shall have a reasonable period of time to comply
with any written request made under this Section 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 the extent any party has an obligation to exercise
commercially reasonable efforts to cause a third party to perform, such party hereunder shall not be required to bring any

contemplated by Item 1108(a)(2)) as servicer or sub-servicer or


 






     -413-


     


    

 


succession
to the Certificate Administrator under this Agreement by any Person (i) into which the Master Servicer and the Special Servicer,
such Sub Servicer or Certificate Administrator may be merged or consolidated, or (ii) which may be appointed as a successor
to the Master Servicer and the Special Servicer or to any such Sub-Servicer or Certificate Administrator, the person removing
and replacing the Master Servicer and the Special Servicer or Certificate Administrator shall provide to the Depositor, the Master
Servicer, the Special Servicer, the Certificate Administrator and each Other Depositor, as applicable, at least fifteen (15) calendar days
prior to the effective date of such succession or appointment (or such shorter period as is agreed to by the Depositor), (x) written
notice to the Depositor, the Other Depositor and the Other Certificate Administrator of such succession or appointment and (y) in
writing and in form and substance reasonably satisfactory to the Depositor, all information relating to such successor reasonably
requested by the Depositor, Other Depositor or Other Certificate Administrator in order to comply with its reporting obligation
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); provided, however that if disclosing such information prior to such effective date
would violate any applicable law or confidentiality agreement, the Master Servicer, the Special Servicer, any Additional Servicer
or the Certificate Administrator, as the case may be, shall submit such disclosure to the Depositor and the Other Depositor no
later than the effective date of such succession or appointment.


 


(b)          Each
of the Master Servicer, the Special Servicer, the Sub-Servicer, the Trustee, the Operating Advisor and the Certificate Administrator
(each of the Master Servicer, the Special Servicer, the Trustee, the Operating Advisor 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


 






     -414-


     


    

 


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 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
notice and/or information furnished or required to be 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.

the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer and the Trustee shall reasonably
cooperate with the Depositor in connection with the satisfaction of the Trust’s reporting requirements under the
Exchange Act. Pursuant to Sections 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 filing thereof, and the Certificate Administrator shall file (via the
Commission’s Electronic Data Gathering and Retrieval System (“EDGAR”)) such Forms executed by the
Depositor.


 


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, 11.11 and 11.15 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 Forms 8-K, Form 10-D, Form ABS-EE or Form 10-K, not resulting from its own negligence, bad
faith or willful misconduct.

proactively
solicit or procure from such parties any Additional Form 10-K Disclosure information. The Depositor will be responsible for

Form 10-K is contingent upon the parties to this Agreement (and any Additional Servicer or Servicing Function
Participant engaged or utilized, as applicable, by any such parties) observing all applicable deadlines in the performance of

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 such Form 10-K, where such failure results from the Certificate Administrator’s failure to
receive, on a timely basis, any information from the parties to this Agreement (or any Sub-Servicer or Servicing Function
Participant engaged by any such parties) needed to prepare, arrange for execution or file such Form 10-K, not resulting
from its own negligence, bad faith or willful misconduct.


 


(c)          Upon
written request from any Mortgage Loan Seller, Other Depositor, the Master Servicer or the Special Servicer, the Certificate Administrator
shall confirm to such Mortgage Loan Seller, Other Depositor, Master Servicer or Special Servicer whether it has


 






     -423-


     


    

 


received
notice that any party to this Agreement has changed since the Closing Date and will provide to such Mortgage Loan Seller or Other
Depositor, the Master Servicer or the Special Servicer, if known to the Certificate Administrator, the identity of the new party.


 


(d)          Any
notice and/or information furnished or required to be furnished pursuant to this Section 11.05 shall also be provided to
each Other Depositor and each Other Certificate Administrator (to the extent the notice and/or information relates to a Serviced
Companion Loan or a party that services, specially services or is trustee or custodian for a Serviced Companion Loan) in the same
time frame as set forth in this Section 11.05.


 


Section
11.06     Sarbanes-Oxley Certification. Each Form 10-K shall include a Sarbanes-Oxley
Certification in the form attached as Exhibit Y required to be included therewith pursuant to the Sarbanes-Oxley
Act. For so long as the Trust or the trust for any Other Securitization is subject to the reporting requirements of the
Exchange Act, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Custodian, the
Operating Advisor and the Asset Representations Reviewer (in the case of the Asset Representations Reviewer, solely with
respect to reporting periods in which the Asset Representations Reviewer is required to deliver an Asset Review Report) shall
provide, and (i) with respect to each Initial Sub-Servicer engaged by the Master Servicer or the Special Servicer, as
the case may be, that is a Servicing Function Participant shall use commercially reasonable efforts to cause such Initial
Sub-Servicer to provide, and (ii) with respect to each other Servicing Function Participant with which the Master
Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Custodian or the Operating Advisor has
entered into a servicing relationship with respect to the Mortgage Loans, shall cause such Servicing Function Participant to
provide, to each Person who signs the Sarbanes-Oxley Certification for the Trust or any Other Securitization that includes a
Serviced Companion Loan (individually and collectively, the “Certifying Person”), on or before
March 1st of each year commencing in March 2018, a certification substantially in the form attached hereto as Exhibits Y-1, Y-2, Y-3, Y-4, Y-5, Y-6 or Y-7
(each, a “Performance Certification”), as applicable, on which each Certifying Person, the entity for
which such Certifying Person acts as an officer (if the Certifying Person is an individual), and such entity’s
officers, directors and Affiliates (collectively with the Certifying Person, “Certification Parties”) can
reasonably rely; provided that, if a Servicing Function Participant (other than an Initial Sub-Servicer) with which
the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Custodian or the Operating Advisor
has entered into a servicing relationship with respect to the Mortgage Loans fails to provide a Performance Certification,
the Performance Certification provided by the Master Servicer, the Special Servicer, the Trustee, the Certificate
Administrator, the Custodian or the Operating Advisor, as applicable, that engaged such Servicing Function Participant shall
not exclude information that would have been provided by such Servicing Function Participant. In addition, in the event that
any Serviced Companion Loan is deposited into a commercial mortgage securitization (an “Other
Securitization”) and the Reporting Servicer is provided with timely and complete contact information for the
parties to such Other Securitization, each Reporting Servicer, upon not less than thirty (30) days prior written request,
shall provide to the Person who signs the Sarbanes-Oxley Certification with respect to such Other Securitization either the
Performance Certification or a separate certification in form and substance similar to applicable Performance
Certification (which shall address the matters contained in the applicable Performance Certification, but solely with respect
to the related Companion Loan) on which such Person, the entity for which the Person acts as an


 






     -424-


     


    

 


officer
(if the Person is an individual), and such entity’s officers, directors and Affiliates can reasonably rely. With respect
to any Non-Serviced Companion Loan, the Certificate Administrator will use its reasonable efforts to procure a Sarbanes-Oxley
Certification from the applicable Non-Serviced Master Servicer, Non-Serviced Special Servicer and Non-Serviced Trustee in form
and substance similar to a Performance Certification. The senior officer in charge of securitization for the Depositor shall serve
as the Certifying Person on behalf of the Trust. In addition, each Reporting Servicer shall execute a reasonable reliance certificate
(which may be included as part of such other certifications being delivered by such Reporting Servicer) to enable the Certification
Parties to rely upon each (i) annual compliance statement provided pursuant to Section 11.09, if applicable, (ii) annual
report on assessment of compliance with servicing criteria provided pursuant to Section 11.10 and (iii) accountant’s
report provided pursuant to Section 11.11, and shall include a certification that each such annual compliance statement
or report discloses any deficiencies or defaults described to the registered public accountants of such Reporting Servicer to
enable such accountants to render the certificates provided for in Section 11.11. In the event any Reporting Servicer is
terminated or resigns pursuant to the terms of this Agreement, or any applicable sub-servicing agreement or primary servicing
agreement, as the case may be, such Reporting Servicer shall provide a certification to each affected Certifying Person pursuant
to this Section 11.06 with respect to the period of time it was subject to this Agreement or the applicable sub-servicing
or primary servicing agreement, as the case may be. Each such Performance Certification shall be provided in EDGAR-Compatible
Format, or in such other format agreed upon by the Depositor, the Certificate Administrator, any affected Other Depositor and
Other Certificate Administrator and such providing parties. Notwithstanding the foregoing, nothing in this Section 11.06
shall require any Reporting Servicer (i) to certify or verify the accurateness or completeness of any information provided
to such Reporting Servicer by third parties (including a “significant obligor”, but other than an Additional Servicer
or a Sub-Servicer appointed pursuant to Section 3.20), (ii) to certify information other than to such Reporting Servicer’s
knowledge and in accordance with such Reporting Servicer’s responsibilities hereunder or (iii) with respect to completeness
of information and reports, to certify anything other than that all fields of information called for in written reports prepared
by such Reporting Servicer have been completed except as they have been left blank on their face.


 


Notwithstanding
anything to the contrary contained in this Section 11.06, with respect to each year in which the Trust and the trust for
each Other Securitization is not subject to the reporting requirements of the Exchange Act, none of the parties required to deliver
any certification under this Section 11.06 shall be obligated to do so.

the 17g-5 Information Provider, a report substantially in the form of Exhibit HH or such other form provided by such
Reporting Servicer that complies in all material respects with the requirements of Item 1122 of Regulation AB, on an
assessment of compliance with the Servicing Criteria applicable to it that contains (A) a statement by such Reporting Servicer

Servicer, as applicable), and (ii) the Certificate Administrator shall confirm that the assessments taken individually address
the Relevant Servicing Criteria for each party as set forth on Exhibit Z and notify the Depositor of any exceptions.
None of the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee, the Operating Advisor or any Servicing
Function Participant shall be required to cause the delivery of any such assessments until April 15th in any given year so
long as it has received written confirmation from the Depositor (or, in the case of an Other Securitization, the related Other
Depositor) that a report on Form 10-K is not required to be filed in respect of the Trust or the trust for any Other Securitization
for the preceding calendar year.

is not otherwise required to provide such information, reports or certificates to any Person in order to comply with Regulation
AB. Such information, reports or certificates shall be provided to the Master Servicer or the Special Servicer, as the case may
be, no later than two (2) Business Days prior to the date on which the Master Servicer or the Special Servicer, as the case may
be, is required to deliver its comparable information, reports, statements or certificates pursuant to this Section 11.15.


 


(g)          With
respect to any Mortgaged Property that secures a Serviced Companion Loan that the applicable Other Depositor has notified the
Master Servicer and the Special Servicer in writing is a “significant obligor” (within the meaning of Item 1101(k)
of Regulation AB) (together with notification of the Relevant Distribution Date) with respect to an Other Securitization
that includes such Serviced Companion Loan, to the extent that the Master Servicer or the Special Servicer, as the case may be,
is in receipt of the updated financial statements of such “significant obligor” for any calendar quarter (other than
the fourth (4th) calendar quarter of any calendar year) from the Mortgagor, beginning with the first calendar quarter in which
such notice from the Other Depositor was received, or the updated financial statements of such “significant obligor”
for any calendar year, beginning for the calendar year in which such notice from the Other Depositor was received, as applicable,
the Master Servicer or the Special Servicer, as the case may be, shall deliver to the Other Depositor, on or prior to the day
that occurs two (2) Business Days prior to the related Significant Obligor NOI Quarterly Filing Deadline or seven (7) Business
Days prior to the related Significant Obligor NOI Yearly Filing Deadline, as applicable, (A) if such financial statement receipt
occurs twelve (12) or more Business Days prior to the related Significant Obligor NOI Quarterly Filing Deadline or seventeen (17)
or more Business Days prior to the related Significant Obligor NOI Yearly Filing Deadline, as applicable, the financial statements
of such “significant obligor”, together with the net operating income of such “significant obligor” for
the applicable period as calculated by the Master Servicer (or by the Special Servicer and provided to the Master Servicer solely
in the case of any related Specially Serviced Loan or Serviced REO Property) in accordance with CREFC® guidelines
and (B) if such financial statement receipt occurs less than twelve (12) Business Day prior to the related Significant Obligor
NOI Quarterly Filing Deadline or less than seventeen (17) Business Days prior to the related Significant Obligor NOI Yearly Filing
Deadline, as applicable, such financial statements of the “significant obligor”, together with the net operating income
of such “significant obligor” for the applicable period as reported by the related Mortgagor in such financial statements
(or by the Special Servicer and provided to the Master Servicer solely in the case of any related Specially Serviced Loan or Serviced
REO Property).


 


If
the Master Servicer or the Special Servicer, as the case may be, does not receive such financial information satisfactory to comply
with Item 6 of Form 10-D or Item 1112(b)(1) of Form 10-K, as the case may be, of such “significant obligor”
within ten (10) Business Days after the date such financial information is required to be delivered under the related Mortgage
Loan documents, the Master Servicer or the Special Servicer, as the case may be, shall notify the Other Depositor with respect
to such Other Securitization that includes the


 






     -440-


     


    

 


related
Serviced Companion Loan (and shall cause each applicable Sub-Servicing Agreement entered into after receipt of written notice
from the Other Depositor that such Serviced Companion Loan is a significant obligor to require the related Sub-Servicer to notify
such Other Depositor) that it has not received such financial information. The Master Servicer (in the case of Non-Specially Serviced
Loans) or the Special Servicer (in the case of Specially Serviced Loans) shall use efforts consistent with the Servicing Standard
(taking into account, in addition, the ongoing reporting obligations of such Other Depositor under the Exchange Act) to obtain
the periodic financial statements required to be delivered by the related Mortgagor under the related Mortgage Loan documents.


 


The
Master Servicer (with respect to Non-Specially Serviced Loans) and the Special Servicer (with respect to Specially Serviced Loans)
shall (and shall cause each applicable Sub-Servicing Agreement entered into after receipt of written notice from the Other Depositor
that such Serviced Companion Loan is a significant obligor to require the related Sub-Servicer to) retain written evidence of
each instance in which it (or a Sub-Servicer) attempts to contact the related Mortgagor related to any such “significant
obligor” (identified to it as such by the Other Depositor in accordance with the second preceding paragraph) to obtain the
required financial information and is unsuccessful and, within five (5) Business Days prior to the date in which a Form 10-D or
Form 10-K, as applicable, is required to be filed with respect to the Other Securitization, shall forward an Officer’s Certificate
evidencing its attempts to obtain this information to the Other Exchange Act Reporting Party and Other Depositor related to such
Other Securitization; provided, however, the Special Servicer shall provide such Officer’s Certificate to
the Master Servicer and the Master Servicer shall forward such Officer’s Certificate to the Other Exchange Act Reporting
Party and Other Depositor related to such Other Securitization. This Officer’s Certificate should be addressed to the certificate
administrator at its corporate trust office, as specified in the related Other Pooling and Servicing Agreement.


 


(h)          If
any Other Securitization includes a Serviced Companion Loan and is subject to the reporting requirements of the Exchange Act,
then the obligations of the parties hereto set forth in this ARTICLE XI with respect such Other Securitization shall remain
in full force and effect notwithstanding that the Trust may cease to be subject to the reporting requirements of the Exchange
Act.


 


Section
11.16     Certain Matters Regarding Significant Obligors. As of the Closing Date, with
respect to the Trust, there is no “significant obligor” within the meaning of Item 1101(k) of Regulation AB
(“Significant Obligor”).


 


Section
11.17     Impact of Cure Period. For the avoidance of doubt, neither the Master Servicer nor
the Special Servicer shall be subject to a Servicer Termination Event pursuant to clause (iii) of the definition
thereof prior to the expiration of the grace period applicable to such party’s obligations
under this ARTICLE XI as provided for in such clause (iii) nor shall any such party be deemed to not be in
compliance under this Agreement, during any grace period provided for in this ARTICLE XI; provided that if any such
party fails to comply with the delivery requirements of this ARTICLE XI by the expiration of any applicable grace period
such failure shall constitute a Servicer Termination Event. Neither the Master Servicer nor the Special Servicer shall be subject
to a Servicer Termination Event pursuant to clause (iii) of the definition thereof prior to the expiration of the
grace period applicable to such party’s

obligations under this ARTICLE XI
as provided for in such clause (iii) nor shall any such party be deemed to not be in compliance under this Agreement,
for failing to deliver any item required under this ARTICLE XI by the time required hereunder with respect to any reporting
period for which the Trust (or any trust in a related Other Securitization) is not required to file Exchange Act reports.

Section
12.01     Asset Review.


 


(a)          On
or prior to each Distribution Date, based either on the CREFC® Delinquent Loan Status Report and/or the CREFC®
Loan Periodic Update File delivered by the Master Servicer for such Distribution Date, 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 notice to all Certificateholders and each other party to this Agreement. Any notice required
to be delivered to the Certificateholders pursuant to this ARTICLE XII shall be delivered by the Certificate Administrator
by posting such notice on the Certificate Administrator’s Website, by mailing such notice to the Certificateholders’
addresses appearing in the Certificate Register in the case of Definitive Certificates and by delivering such notice via the Depository
in the case of Book-Entry Certificates. The Certificate Administrator shall include in the Form 10-D relating to the reporting
period in which the Asset Review Trigger occurred the following statement describing the events that caused the Asset Review Trigger
to occur: “As of the [Date of Distribution], the following Mortgage Loans identified below are sixty (60) or more days delinquent
and an Asset Review Trigger as defined in the Pooling and Servicing Agreement has occurred.”. On each Distribution Date
occurring after providing such notice to Certificateholders, the Certificate Administrator, based on information provided to it
by the Master Servicer or the Special Servicer, as the case may be, 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) whether 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 such information in a written notice (which may be via email) in the form of Exhibit RR
within two (2) Business Days to the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations
Reviewer.


 


If
Certificateholders (other than Holders of the RR Interest) evidencing not less than 5% of the Voting Rights of the Certificates
deliver to the Certificate Administrator, within ninety (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 (an “Asset Review Vote Election”),
then the Certificate Administrator shall promptly provide written notice thereof to all Certificateholders (with a copy to the
Asset Representations Reviewer) and conduct a solicitation of votes in accordance with Section 5.10 to authorize an Asset
Review. Upon the affirmative vote to authorize an Asset Review by Holders of Certificates evidencing at least (i) a


 






     -442-


     


    

 


majority
of those Certificateholders who cast votes and (ii) a majority of an Asset Review Quorum within one hundred fifty (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 Certificateholder, the Risk Retention Consultation Party and the other 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 the Certificate Administrator with a certification substantially in the form attached hereto as Exhibit QQ
(which shall be sent via email to trustadministrationgroup@wellsfargo.com or submitted electronically via the Certificate
Administrator’s Website). 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 one hundred fifty (150) day period following the receipt of
the Asset Review Vote Election, no Certificateholder may request a vote or cast a vote for an Asset Review and the Asset Representations
Reviewer will 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 one hundred fifty (150) day period, (B) a new Asset Review Trigger has occurred
as a result or an Asset Review Trigger is otherwise in effect, (C) the Certificate Administrator has timely received any
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 one hundred fifty (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 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)  Upon
receipt of an Asset Review Notice, the Custodian (with respect to clauses (1) - (5) below for all Mortgage
Loans), the Master Servicer (with respect to clause (6) below for Non-Specially Serviced Loans) and the Special Servicer
(with respect to clause (6) below for 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, provide the following materials in electronic format
to the Asset Representations Reviewer (collectively, with the Diligence Files posted on the Secure Data Room by the Certificate
Administrator pursuant to Section 4.08, a copy of the Prospectus, a copy of each related Mortgage Loan Purchase Agreement
and a copy of this Agreement, 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


 






     -443-


     


    

 


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 clause (1) or clause (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; and


 


(6)          any
other related documents that were entered into or delivered in connection with the origination of the related Mortgage Loan that
the Asset Representations Reviewer has determined are necessary in connection with its completion of any Asset Review and that
are requested by the Asset Representations Reviewer, in the time frames and as otherwise described in clause (ii)
hereof.


 


(ii)          In
addition, in the event that, as part of an Asset Review of a Mortgage Loan, the Asset Representations Reviewer determines it is
missing any document that is required to be part of the Review Materials for such Mortgage Loan and that is necessary in connection
with its completion of the 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 document(s), and request that
the Master Servicer or the Special Servicer, as the case may be, promptly, but in no event later than ten (10) Business Days after
receipt of notification from the Asset Representations Reviewer, deliver to the Asset Representations Reviewer such missing document(s)
to the extent in its possession; provided that any such notification and/or request shall be in writing, specifically identifying
the documents being requested and sent to the notice address for the related party set forth in Section 13.05 of this Agreement.
In the event any missing documents are not provided by the Master Servicer or the Special Servicer, as the case may be, within
such ten (10) Business Day period, the Asset Representations Reviewer shall request such documents from the related Mortgage Loan
Seller; provided that the Mortgage Loan Seller is required under the related Mortgage Loan Purchase Agreement to deliver
such missing document only to the extent such document is in the possession of such party but in any event excluding any documents
that contain information that is proprietary to the related originator or Mortgage Loan Seller or any draft documents or privileged
or internal communications.


 


(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


 






     -444-


     


    

 


Agreement
or the applicable 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 conducted pursuant to this Section 12.01 (any such information,
“Unsolicited Information”).


 


(iv)          Upon
receipt by the Asset Representations Reviewer of the Asset Review Notice and access to the Diligence File with respect to a Delinquent
Loan, the Asset Representations Reviewer, as an independent contractor, shall commence a review of the compliance of each Delinquent
Loan with the representations and warranties related to that Delinquent Loan (such review, the “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 procedures set forth on Exhibit PP
(each such procedure, a “Test”); provided, however, that the Asset Representations Reviewer
may, but is under no obligation to, modify any Test and/or associated Review Materials if, and only to the extent, the Asset Representations
Reviewer determines pursuant to the Asset Review Standard that it is necessary to modify such Test and/or such associated Review
Materials in order to facilitate its Asset Review in accordance with the Asset Review Standard. 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 (1) the Review Materials and (2) 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)          The
Asset Representations Reviewer shall prepare a preliminary report with respect to each Delinquent Loan within fifty-six (56) days
after the date on which access to the Secure Data Room is provided. In the event that the Asset Representations Reviewer determines
that the Review Materials are insufficient to complete a Test and such missing documentation is not delivered to the Asset Representations
Reviewer by the related Mortgage Loan Seller, 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 Servicer’s
possession within ten (10) Business Days following the request by the Asset Representations Reviewer to the Master Servicer, the
Special Servicer or the related Mortgage Loan Seller, as the case


 






     -445-


     


    

 


may
be, as described in Section 12.01(b)(ii), the Asset Representations Reviewer shall list such missing documents in such
preliminary report setting forth the preliminary results of the application of the Tests and the reasons why such missing documents
are necessary to complete a Test and (if the Asset Representations Reviewer has so concluded) that the absence of such documents
will be deemed to be a failure of such Test. The Asset Representations Reviewer shall provide such preliminary report to the Master
Servicer (only with respect to Non-Specially Serviced Loans), 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 documents or explanations to support the related 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 sent by such Mortgage Loan Seller to the Asset Representations Reviewer. For 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 sixty (60) days after the date on which access to the Secure Data Room is provided
to the Asset Representations Reviewer by the Certificate Administrator or within the ten (10) days after the expiration of the
Cure/Contest Period (whichever is later), 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, the related Mortgage Loan Seller for each Delinquent Loan, the Directing Certificateholder 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 the 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 applicable 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 Loan 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 applicable Mortgage Loan Seller (or, in the case
of Ladder Capital Finance LLC, against Ladder Capital Finance Holdings LLLP, Series REIT of Ladder Capital Finance Holdings LLLP
and Series TRS of Ladder Capital Finance Holdings LLLP in respect of their respective payment guaranties), which, in each case,
shall be a responsibility of the applicable Enforcing Servicer pursuant to Section 2.03(k) of this Agreement.


 


(ix)          In
addition, in the event that the Asset Representations Reviewer does not receive any documentation that it requested from the Master
Servicer (with respect to


 






     -446-


     


    

 


Non-Specially
Serviced Loans), 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 Report, the Asset Representations
Reviewer shall prepare the Asset Review Report solely based on the documentation 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 documentation from any party to this Agreement or otherwise.


 


(x)          Within
thirty (30) days after receipt of an Asset Review Report with respect to any Mortgage Loan, the Special Servicer shall determine,
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 applicable Mortgage Loan Seller with
respect to such Material Defect in accordance with Section 2.03(b).


 


(c)          The
Asset Representations Reviewer and its affiliates shall keep confidential any information appropriately labeled as “Privileged
Information” received from any party to this Agreement or any Sponsor (including, without limitation, in connection with
the review of the Mortgage Loans) and 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 (i) be affiliated with any Mortgage Loan Seller, the 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, the 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


 






     -447-


     


    

 


agent
or subcontractor, and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.


 


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 the Mortgage
Loans and shall be equal to the product of a rate equal to 0.00030% per annum (the “Asset Representations Reviewer
Fee Rate”) and the Stated Principal Balance of the Mortgage Loans and any REO Loans (including any Non-Serviced Mortgage
Loan, but not any Companion Loan) and shall be calculated in the same manner as interest is calculated on such Mortgage 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, upon the completion of any Asset Review with respect to an
individual Asset Review Trigger, the Asset Representations Reviewer shall be paid a fee equal to, in the case of a Delinquent
Loan, the sum of: (i) $15,000 plus $1,000 per additional Mortgaged Property with respect to a Delinquent Loan with a Cut-off
Date Balance less than $20,000,000, (ii) $20,000 plus $1,000 per additional Mortgaged Property with respect to a Delinquent Loan
with a Cut-off Date Balance greater than or equal to $20,000,000, but less than $40,000,000 or (iii) $25,000 plus $1,000 per additional
Mortgaged Property with respect to a Delinquent Loan with a Cut-off Date Balance greater than or equal to $40,000,000 (any such
fee, the “Asset Representations Reviewer Asset Review Fee”). The Asset Representations Reviewer Asset Review
Fee with respect to each Delinquent Loan shall be paid by the related Mortgage Loan Seller; provided, however, that
if the related Mortgage Loan Seller is insolvent or fails to pay such amount within ninety (90) days of written request by
the Asset Representations Reviewer, such fee shall be paid by the Trust following delivery by the Asset Representations Reviewer
of a certification to the Master Servicer that the requirements for payment set forth in this Section 12.02(b) have been
met. The Asset Representations Reviewer shall not deliver any such certificate unless it has invoiced payment of such amount and
otherwise met the requirements for payment set forth in this Section 12.02(b), including receipt of evidence of such insolvency
or failure to pay such amount. A Mortgage Loan Seller shall be deemed to have failed to pay such amount hereunder ninety (90)
days after delivery by the Asset Representations Reviewer of an itemized invoice to such Mortgage Loan Seller by registered mail
or overnight courier to the address listed in this Agreement for such Mortgage Loan Seller, or to such other address as shall
be provided by such Mortgage Loan Seller for delivery of notices in accordance with this Agreement, or ninety (90) days following
attempted delivery of such invoice by registered mail or overnight courier and reasonable follow -up by telephone or e-mail. 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 Enforcing Servicer shall pursue remedies against such Mortgage Loan Seller to recover any such amounts
to the extent paid by the Trust.


 






     -448-


     


    

 


(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 that is repurchased or substituted by a
Mortgage Loan Seller, and such portion of the Purchase Price received shall be used to reimburse the Asset Representations Reviewer
or the Trust, as the case may be, for such fees 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 at any time resign and be discharged from its obligations hereunder by giving 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. If no successor asset representations
reviewer shall have been so appointed and have accepted appointment within thirty (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 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

by the Holders of Certificates having greater than 25% of the Voting Rights, provided that any such failure that is not curable
within such thirty (30) day period, the Asset Representations Reviewer shall have an additional cure period of thirty (30) days
to effect such cure so long as it has commenced to cure such failure within the initial thirty (30) day period and has provided
the Trustee and the Certificate Administrator with an officer’s certificate certifying that it has diligently pursued, and
is continuing to pursue, such cure;


 


(ii)          any
failure by the Asset Representations Reviewer to perform its obligations hereunder in accordance with the Asset Review Standard

of such failure, requiring the same to be remedied, is given to the Asset Representations Reviewer by any party to this Agreement;


 


(iii)         any

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 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 of written notice of the occurrence of any Asset Representations Reviewer Termination
Event, the Certificate Administrator shall promptly provide written notice to all Certificateholders (which shall be simultaneously
delivered to the Asset Representations Reviewer) 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,

or (ii) upon the written direction of Holders of


 






     -450-


     


    

 


Certificates evidencing not less than 25% of the Voting Rights (without
regard to the application of any Cumulative Appraisal Reduction Amounts), 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 itself and 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 and each Mortgage Loan Seller 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 Holders of Certificates evidencing not less than 25% of the 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 Certificateholders by (i) posting such notice on its internet website, and (ii) mailing
such notice to all Certificateholders at their addresses appearing in the Certificate Register and to the Asset Representations
Reviewer. Upon the written direction of Holders of Certificates evidencing at least 75% of a 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 and appoint the proposed successor. As between the Asset Representations Reviewer,
on the one hand, and the Certificateholders, on the other, the 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 Holders of the
Certificates evidencing at least 75% of a 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 thirty
(30) 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


 






     -451-


     


    

 


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 and each Certificateholder within one Business Day of such appointment.


 


The
Asset Representations Reviewer shall at all times be 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
the Master Servicer, the Special Servicer, the Trustee, the Operating Advisor, the Certificate Administrator and the Directing
Certificateholder 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 thirty (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 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 Mortgage Loan Sellers, the Depositor, each Rating Agency, and, prior to the occurrence and continuance of a Consultation Termination
Event and the Directing Certificateholder. 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).

    	A-1-7 



     


    

 


[FOR
REGULAR CERTIFICATES: This Certificate represents 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 “Code”).] 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.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator shall distribute 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 [FOR PRINCIPAL BALANCE
CERTIFICATES (CLASS A-1, A-2, A-SB, A-3, A-4, A-S, B, C, D, E, F, G and NR): principal and] interest then distributable, if any,
allocable to the Class of Certificates of the same Class as this Certificate for such Distribution Date, all as more fully described
in the Pooling and Servicing Agreement. [FOR CLASS A-1, A-2, A-SB, A-3, A-4, A-S, B, C, X-A and X-B CERTIFICATES: Holders of this
Certificate may be entitled to Prepayment Premiums and Yield Maintenance Charges as provided in the Pooling and Servicing Agreement.]
All sums distributable on this Certificate are payable in the coin or currency of the United States of America as at the time
of payment is legal tender for the payment of public and private debts.


 


Interest
on this Certificate will accrue (computed as if each year consisted of 360 days and each month consisted of 30 days) during the
Interest Accrual Period relating to such Distribution Date at the Pass-Through Rate specified above on the Certificate Balance
of this Certificate immediately prior to each Distribution Date. [FOR CLASS X CERTIFICATES: Interest][FOR PRINCIPAL BALANCE CERTIFICATES
(CLASS A-1, A-2, A-SB, A-3, A-4, A-S, B, C, D, E, F, G and NR): Principal and interest] allocated to this Certificate on any Distribution
Date will be in an amount equal to this Certificate’s pro rata share of the Available Funds to be distributed on
the Certificates of this Class as of such Distribution Date, with a final distribution to be made upon retirement of this Certificate
as set forth in the Pooling and Servicing Agreement.


 


Realized
Losses and certain other amounts on the Mortgage Loans shall be allocated on the applicable Distribution Date to Certificateholders
in the manner set forth in the Pooling and Servicing Agreement. All Realized Losses on the Mortgage Loans allocated to any Class
of Certificates will be allocated pro rata among the outstanding Certificates of such Class.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries respecting the Mortgage
Loans, all as more specifically set forth in the Pooling and Servicing Agreement. As provided in the Pooling and Servicing Agreement,
the Collection Account and the Distribution Accounts will be held on behalf of the Trustee for the benefit of the Holders of Certificates
specified in the Pooling and Servicing Agreement and the Master Servicer (with respect to the Collection Account) or the Certificate
Administrator (with respect to the Distribution Accounts) will be authorized to make withdrawals therefrom. Amounts on deposit
in such accounts may be invested in Permitted Investments. Interest or other investment income earned on funds in the Collection
Account will be paid to the Master


 



    	A-1-8 



     


    

 


Servicer as set forth in the Pooling and Servicing Agreement. As provided in the Pooling and
Servicing Agreement, withdrawals from the Collection Account shall be made from time to time for purposes other than distributions
to Certificateholders, such purposes including reimbursement of certain expenses incurred with respect to the servicing of the
Mortgage Loans and administration of the Trust.


 


All
distributions under the Pooling and Servicing Agreement to a Class of Certificates shall be made on each Distribution Date (other
than the final distribution on any Certificate) to Certificateholders of record on the related Record Date by check mailed to
the address set forth therefor in the Certificate Register or, provided that such Certificateholder has provided the Certificate
Administrator with wire instructions at least five (5) Business Days prior to the related Record Date, by wire transfer of immediately
available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor. The
final distribution on this Certificate (determined without regard to any possible future reimbursement of Realized Losses previously
allocated to this Certificate) shall be made in like manner, but only upon presentment and surrender of this 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(h) 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. 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(h) of the Pooling and Servicing
Agreement.


 


As
provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate
is registerable in the Certificate Register only upon surrender of this Certificate for registration of transfer at the office
of the Certificate Registrar or at the office of its transfer agent, duly endorsed by, or accompanied by an assignment in the
form below or other written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder
hereof or such Holder’s attorney-in-fact duly authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized Denominations will be issued to the designated transferee or transferees.

(viii)       to
modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable

a Control Termination Event has not occurred and is not continuing and with respect to the Mortgage Loans other than any Excluded
Loan as to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder,
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

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

required to comply with any such amendment or, to the extent applicable, to modify or eliminate the affected provision(s) 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 or rights of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise


 



    	A-1-12 



     


    

 


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 change any provision specifically required to be included in the Pooling and Servicing Agreement
by any related Intercreditor Agreement or otherwise materially and adversely affect the holder 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 Holder of an RR Interest) 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 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, 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 rights 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 shall consent to any amendment to the Pooling and Servicing


 



    	A-1-13 



     


    

 


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 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, any Trust REMIC or the Grantor Trust, 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. Furthermore, no amendment to the Pooling
and Servicing Agreement may be made that changes any provision specifically required to be included in the Pooling and Servicing
Agreement by an Intercreditor Agreement related to a Companion Loan without, in each case, the consent of the holder of the related
Companion Loan(s).


 


The
Holder 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) and the Trust’s portion of each REO Property remaining in
the Trust Fund as contemplated by clause (ii) of the first paragraph of Section 9.01 in the Pooling and Servicing Agreement by
giving written notice to the Trustee, the Certificate Administrator and the other parties to the Pooling and Servicing Agreement
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 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 Balances of the Mortgage 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.


 


Following
the date on which the Class A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B, Class C and Class D Certificates
are no longer outstanding (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)
for all of the Mortgage 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 Certificateholder by virtue of the acceptance hereof assents and by which the Certificateholder is bound. In the case of any
conflict between terms specified in this Certificate and terms specified in the Pooling and Servicing Agreement, the terms of
the Pooling and Servicing Agreement shall govern.


 


This
Class Z Certificate represents an undivided beneficial interest in a portion of a grantor trust that holds the Excess Interest
and related amounts in 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


 



    	A-2-4 



     


    

 


taxes and other taxes imposed on or measured by income.


 


Pursuant
to the terms of the Pooling and Servicing Agreement the Certificate Administrator shall distribute 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 Excess Interest then distributable, if any, allocable to the Class
of Certificates of the same Class as this Certificate for such Distribution Date, all as more fully described in the Pooling and
Servicing Agreement. All sums distributable on this Certificate are payable in the coin or currency of the United States of America
as at the time of payment is legal tender for the payment of public and private debts.


 


This
Certificate is limited in right of payment to, among other things, Excess Interest actually collected on the Mortgage Loans, all
as more specifically set forth in the Pooling and Servicing Agreement. As provided in the Pooling and Servicing Agreement, the
Collection Account and the Distribution Accounts will be held on behalf of the Trustee for the benefit of the Holders of Certificates
specified in the Pooling and Servicing Agreement and the Master Servicer (with respect to the Collection Account) or the Certificate
Administrator (with respect to the Distribution Accounts) will be authorized to make withdrawals therefrom. Amounts on deposit
in such accounts may be invested in Permitted Investments. Interest or other investment income earned on funds in the Collection
Account will be paid to the Master Servicer as set forth in the Pooling and Servicing Agreement. As provided in the Pooling and
Servicing Agreement, withdrawals from the Collection Account shall be made from time to time for purposes other than distributions
to Certificateholders, such purposes including reimbursement of certain expenses incurred with respect to the servicing of the
Mortgage Loans and administration of the Trust.


 


All
distributions under the Pooling and Servicing Agreement to a Class of Certificates shall be made on each Distribution Date (other
than the final distribution on any Certificate) to Certificateholders of record on the related Record Date by check mailed to
the address set forth therefor in the Certificate Register or, provided that such Certificateholder has provided the Certificate
Administrator with wire instructions at least five (5) Business Days prior to the related Record Date, by wire transfer of immediately
available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor. The
final distribution on this Certificate shall be made in like manner, but only upon presentment and surrender of this 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 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 Section 4.01(h) 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, 


 



    	A-2-5 



     


    

 


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, subject to applicable law with respect to escheatment
of funds. 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(i) of the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate
is registerable in the Certificate Register only upon surrender of this Certificate for registration of transfer at the office
of the Certificate Registrar or at the office of its transfer agent, duly endorsed by, or accompanied by an assignment in the
form below or other written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder
hereof or such Holder’s attorney-in-fact duly authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized Denominations will be issued to the designated transferee or transferees.


 


The
Class Z Certificates shall be issued, maintained and transferred in minimum percentage interests of 5% of such Class Z
Certificates and in integral multiples of 1 in excess thereof.


 


No
fee or service charge shall be imposed by the Certificate Registrar for its services in respect of any registration of transfer
or exchange of any Certificate (other than Definitive Certificates) referred to in Section 5.03 of the Pooling and Servicing Agreement.
In connection with any transfer to an Institutional Accredited Investor, the Transferor shall reimburse the Trust for any costs
(including the cost of the Certificate Registrar’s counsel’s review of the documents and any legal opinions, submitted
by the transferor or transferee to the Certificate Registrar as provided in Section 5.03 of the Pooling and Servicing Agreement)
incurred by the Certificate Registrar in connection with such transfer. The Certificate Registrar may require payment by each
transferor of a sum sufficient to cover any tax, expense or other governmental charge payable in connection with any such transfer
or exchange.


 


The
Trustee, the Certificate Administrator, the Master Servicer, the Special Servicer and the Certificate Registrar, and any agent
of any of them, may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither
the Trustee, the Certificate Administrator, the Master Servicer, the Special Servicer, the Certificate Registrar, nor any agent
of any of them, shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the parties thereto, 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 in order to address any manifest error in any provision
of the Pooling and Servicing Agreement;


 






    	A-2-6 



     


    

 


(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 defective or 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 an RR 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, 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 an RR 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 Disqualified 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 an RR 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 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



 



    	A-2-7 



     


    

 


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 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 an RR 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 the Mortgage Loans other than any Excluded
Loan as to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder,
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 Holder of an RR 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;


 






    	A-2-8 



     


    

 


(x)       to
modify, eliminate or add to any of its provisions to such extent as will 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 Risk Retention Rules or any other regulations applicable to
the risk retention requirements for this securitization transaction are amended or repealed in whole or in part, to the extent
required to comply with any such amendment or, to the extent applicable, to modify or eliminate the affected provision(s) 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 or rights 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 change any provision specifically required to be included in the Pooling and Servicing Agreement
by any related Intercreditor Agreement or otherwise materially and adversely affect the holder 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 Holder of an RR Interest) 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 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, 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 rights 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


 






    	A-2-9 



     


    

 


(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 shall 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 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, any Trust REMIC or the Grantor Trust, 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. Furthermore, no amendment to the Pooling
and Servicing Agreement may be made that changes any provision specifically required to be included in the Pooling and Servicing
Agreement by an Intercreditor Agreement related to a Companion Loan without, in each case, the consent of the holder of the related
Companion Loan(s).


 


The
Holder 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) and the Trust’s portion of each REO Property remaining in
the Trust Fund as contemplated by clause (ii) of the first paragraph of Section 9.01 in the Pooling and Servicing Agreement by
giving written notice to the Trustee, the Certificate Administrator and the other parties to the Pooling and Servicing Agreement
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 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 Balances of the Mortgage 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.


 


Following
the date on which the Class A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B, Class C and Class D Certificates
are no longer outstanding (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


 



    	A-2-10 



     


    

 


its Certificates (other than the Class Z and Class R Certificates)
for all of the Mortgage 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
or the Mortgage Loans.


 


THIS
CERTIFICATE AND THE POOLING AND SERVICING AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY THE LAWS OF THE STATE
OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES APPLIED IN NEW YORK.

THIS
CERTIFIES THAT [____________________] is the registered owner of the interest evidenced by this Certificate in the Class R Certificates
issued by the Trust created pursuant to the Pooling and Servicing Agreement, dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between UBS COMMERCIAL MORTGAGE SECURITIZATION CORP. (hereinafter called the “Depositor”,
which term includes any successor entity under the Pooling and Servicing Agreement), the Trustee, the Master Servicer, the Special
Servicer, the Fairmount at Brewerytown Special Servicer, the Certificate Administrator, the Operating Advisor and the Asset Representations
Reviewer. A summary of certain of the pertinent provisions of the Pooling and Servicing Agreement is set forth hereafter. To the
extent not defined herein, the capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing
Agreement.


 


This
Certificate is one of a duly authorized issue of Certificates designated as Certificates of the series specified on the face hereof
(herein called the “Certificates”) and representing a percentage interest in the Class of Certificates specified
on the face hereof. The Certificates are designated as the UBS COMMERCIAL MORTGAGE TRUST 2017-C4, Commercial Mortgage Pass-Through
Certificates, Series 2017-C4 and are issued in the classes as specifically set forth in the Pooling and Servicing Agreement.
The Certificates will evidence in the aggregate 100% of the beneficial ownership of the Trust Fund.


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement and reference is made to that agreement for information
with respect to the interests, rights, benefits, obligations, proceeds, and duties evidenced hereby and the rights, duties and
obligations of the Trustee and the Certificate Administrator. This Certificate is issued under and is subject to the terms, provisions
and conditions of the Pooling and Servicing Agreement, to which Pooling and Servicing Agreement, as amended from time to time,
the Certificateholder by virtue of the acceptance hereof assents and by which the Certificateholder is bound. In the case of any
conflict between terms specified in this Certificate and terms specified in the Pooling and Servicing Agreement, the terms of
the Pooling and Servicing Agreement shall govern.


 


This
Class R Certificate represents a “residual interest” in two “real estate mortgage investment conduits”,
as those terms are defined, respectively, in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended (the
“Code”). 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


 



    	A-3-5 



     


    

 


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 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 applicable to the Trust REMICs) for each Trust REMIC, and the Certificate Administrator
is hereby irrevocably designated and shall serve (i) as attorney-in-fact and agent for any such Person that is the “tax
matters person” and (ii) as the “partnership representative” for each Trust REMIC within the meaning of Section
6223 of the Code (to the extent such provision is applicable to the Trust REMIC).


 


Pursuant
to the terms of the Pooling and Servicing Agreement, distributions, if any, on this Certificate shall be made by the Certificate
Administrator in an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by
this Certificate) and to the extent and subject to the limitations set forth in the Pooling and Servicing Agreement, on the Distribution
Date to the Person in whose name this Certificate is registered as of the related Record Date. All sums distributable on this
Certificate are payable in the coin or currency of the United States of America as at the time of payment is legal tender for
the payment of public and private debts.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries respecting the Mortgage
Loans, all as more specifically set forth in the Pooling and Servicing Agreement. As provided in the Pooling and Servicing Agreement,
the Collection Account and the Distribution Accounts will be held on behalf of the Trustee for the benefit of the Holders of Certificates
specified in the Pooling and Servicing Agreement and the Master Servicer (with respect to the Collection Account) or the Certificate
Administrator (with respect to the Distribution Accounts) will be authorized to make withdrawals therefrom. Amounts on deposit
in such accounts may be invested in Permitted Investments. Interest or other investment income earned on funds in the Collection
Account will be paid to the Master Servicer as set forth in the Pooling and Servicing Agreement. As provided in the Pooling and
Servicing Agreement, withdrawals from the Collection Account shall be made from time to time for purposes other than distributions
to Certificateholders, such purposes including reimbursement of certain expenses incurred with respect to the servicing of the
Mortgage Loans and administration of the Trust.


 


All
distributions under the Pooling and Servicing Agreement to a Class of Certificates shall be made on each Distribution Date (other
than the final distribution on any Certificate) to Certificateholders of record on the related Record Date by check mailed to
the address set forth therefor in the Certificate Register or, provided that such Certificateholder has provided the Certificate
Administrator with wire instructions at least five (5) Business Days prior to the related Record Date, by wire transfer of immediately
available funds to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor. The
final distribution on this Certificate shall be made in like manner, but only upon presentment and surrender of this 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


 






    	A-3-6 



     


    

 


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(h) 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. 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(h) of the Pooling and Servicing
Agreement.


 


As
provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate
is registerable in the Certificate Register only upon surrender of this Certificate for registration of transfer at the office
of the Certificate Registrar or at the office of its transfer agent, duly endorsed by, or accompanied by an assignment in the
form below or other written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder
hereof or such Holder’s attorney-in-fact duly authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized Denominations will be issued to the designated transferee or transferees.


 


Each
Person who has or who acquires any Ownership Interest in a Class R Certificate shall be deemed by the acceptance or
acquisition of such Ownership Interest to have agreed to be bound by the following provisions. The rights of each Person
acquiring any Ownership Interest in a Class R Certificate are expressly subject to the following provisions: (A) no Person
holding or acquiring any Ownership Interest in a Class R Certificate shall be a Disqualified Organization or agent thereof
(including a nominee, middleman or similar person) (an “Agent”), a Plan or a Person acting on behalf of or
investing the assets of a Plan (such Plan or Person, an “ERISA Prohibited Holder”) or a Disqualified
Non-U.S. Tax Person and shall promptly notify the Certificate Registrar of any change or impending change to such status;
(B) in connection with any proposed Transfer of any Ownership Interest in a Class R Certificate, 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 to
the Pooling and Servicing Agreement 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 tax 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 


 



    	A-3-7 



     


    

 





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 Section 5.03(o)
of the Pooling and Servicing Agreement 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.


 


The
Class R Certificates will be issued in fully registered, certificated form, in minimum percentage interests of 10% and integral
multiples of 1% in excess thereof.


 


No
fee or service charge shall be imposed by the Certificate Registrar for its services in respect of any registration of transfer
or exchange of any Certificate (other than Definitive Certificates) referred to in Section 5.03 of the Pooling and Servicing Agreement.
In connection with any transfer to an Institutional Accredited Investor, the Transferor shall reimburse the Trust for any costs
(including the cost of the Certificate Registrar’s counsel’s review of the documents and any legal opinions, submitted
by the transferor or transferee to the Certificate Registrar as provided in Section 5.03 of the Pooling and Servicing Agreement)
incurred by the Certificate Registrar in connection with such transfer. The Certificate Registrar may require payment by each
transferor of a sum sufficient to cover any tax, expense or other governmental charge payable in connection with any such transfer
or exchange.


 


The
Trustee, the Certificate Administrator, the Master Servicer, the Special Servicer and the Certificate Registrar, and any agent
of any of them, may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither
the Trustee, the Certificate Administrator, the Master Servicer, the Special Servicer, the Certificate Registrar, nor any agent
of any of them, shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the parties thereto, 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 in order to address any manifest error in any provision
of 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 defective or inconsistent
with any other provisions therein or to correct any error;


 






    	A-3-8 



     


    

 


(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,

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, 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 an RR 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 Disqualified 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

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 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


 



    	A-3-9

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); 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 an RR 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 the Mortgage Loans other than any Excluded
Loan as to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder,
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 Holder of an RR 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 of its provisions to such extent as will be necessary to comply with the requirements for use

(xi)       to
modify, eliminate or add to any of its provisions in the event the Risk Retention Rules or any other regulations applicable to
the risk retention requirements for this securitization transaction are amended or repealed in whole or in part, to the extent


 



    	A-3-10 



     


    

 



required to comply with any such amendment or, to the extent applicable, to modify or eliminate the affected provision(s) 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 or rights 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 change any provision specifically required to be included in the Pooling and Servicing Agreement
by any related Intercreditor Agreement or otherwise materially and adversely affect the holder 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 Holder of an RR Interest) 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 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, 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 rights 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


 



    	A-3-11 



     


    

 


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 shall 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 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, any Trust REMIC or the Grantor Trust, 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. Furthermore, no amendment to the Pooling
and Servicing Agreement may be made that changes any provision specifically required to be included in the Pooling and Servicing
Agreement by an Intercreditor Agreement related to a Companion Loan without, in each case, the consent of the holder of the related
Companion Loan(s).


 


The
Holder 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) and the Trust’s portion of each REO Property remaining in
the Trust Fund as contemplated by clause (ii) of the first paragraph of Section 9.01 in the Pooling and Servicing Agreement by
giving written notice to the Trustee, the Certificate Administrator and the other parties to the Pooling and Servicing Agreement
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 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 Balances of the Mortgage 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.


 


Following
the date on which the Class A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B, Class C and Class D Certificates
are no longer outstanding (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)
for all of the Mortgage 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


 



    	A-3-12 



     


    

 


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
or the Mortgage Loans.


 


THIS
CERTIFICATE AND THE POOLING AND SERVICING AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY THE LAWS OF THE STATE
OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES APPLIED IN NEW YORK.

		☐	The
                                         Purchaser is not purchasing a Class R Certificate and the Purchaser is an institution
                                         that is an “accredited investor” within the meaning of Rule 501(a)(1), (2),
                                         (3) or (7) of Regulation D (“Regulation D”) under the Securities Act

                                         Investor”) and has such knowledge and experience in financial and business
                                         matters as to be capable of evaluating the merits and risks of its investment in the
                                         Certificates, and the Purchaser and any accounts for which it is acting are each able
                                         to bear the economic risk of the Purchaser’s or such account’s investment.
                                         The Purchaser is acquiring the Certificates purchased by it for its own account or for
                                         one or more accounts, each of which is an Institutional Accredited Investor, as to each
                                         of which the Purchaser exercises sole investment discretion. The Purchaser hereby undertakes
                                         to reimburse the Trust for any costs incurred by it in connection with this transfer.



 


		☐	The
                                         Purchaser is a “qualified institutional buyer” (a “QIB”)
                                         within the meaning of Rule 144A (“Rule 144A”) under the Securities

                                         pursuant to paragraph (d)(4)(i) of Rule 144A.



 


2.       The
Purchaser’s intention is to acquire the Certificates (a) for investment for the Purchaser’s own account or (b) for
reoffer, resale, pledge or other transfer (i) to QIBs in transactions under Rule 144A, and not in any event with the view to,
or for resale in connection with, any distribution thereof, or (ii) (other than with respect to a Class R Certificate) to Institutional
Accredited Investors, subject in the case of clause (ii) above to (w) the receipt by the Certificate Registrar of a letter substantially
in the form hereof, (x) the receipt by the Certificate Registrar of an opinion of counsel acceptable to the Trustee and Certificate

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” and (ii) “Upper-Tier
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 thereof, to a Disqualified Organization. For the purposes hereof, a Disqualified Organization is


 



    Exhibit D-1-1 


     


    

 


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 the Federal Home Loan Mortgage Corporation, 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 a 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 October 1, 2017 (the “Pooling and Servicing Agreement”), by and among UBS Commercial
Mortgage Securitization Corp., as Depositor, Wells Fargo Bank, National Association, as Master Servicer, Rialto Capital Advisors,
LLC, as Special Servicer, AEGON USA Realty Advisors, LLC, as Fairmount at Brewerytown Special Servicer, Wells Fargo Bank, National
Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, and Pentalpha Surveillance LLC,
as Operating Advisor and as Asset Representations Reviewer. 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


 



    Exhibit D-2-1 


     


    

 


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 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.


 


	 	Very truly yours,
	 	 	 
	 	(Transferor)

other than as a result of a disclosure by you or a NRSRO Representative (as defined in Section 2(c)(i) below) in violation
of this Confidentiality Agreement;


 


was or is lawfully
obtained by you from a source other than a Furnishing Entity or its representatives that (i) is reasonably believed by you

who is informed of the matters that are the subject of this Confidentiality Agreement to that effect.


 


You will treat the
Confidential Information as private and confidential. Subject to Section 4, without the prior written consent of the applicable
Furnishing Entity, you will not disclose to any person any Confidential Information, whether such Confidential Information was
furnished to you before, on or after the date of this Confidentiality Agreement. Notwithstanding the foregoing, you may:


 



    Exhibit P-2-3


     


    

 


disclose
the Confidential Information to any of the NRSRO’s affiliates, directors, officers, employees, legal representatives, agents
and advisors (each, a “NRSRO Representative”) who, in the reasonable judgment of the NRSRO, need to know such

such NRSRO Representative will act in accordance with this Confidentiality Agreement;

Confidential Information.


 


Disclosures Required by Law. If
you or any NRSRO Representative is requested or required (orally or in writing, by interrogatory, subpoena, civil investigatory
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
the extent practical and permitted by law, regulation or regulatory or other governmental authority) that a request to disclose
the Confidential Information has been made so that the relevant Furnishing Entity may seek an appropriate protective order or other
reasonable assurance that confidential treatment will be accorded the Confidential Information if it so chooses. Unless otherwise
required by a court or other governmental or regulatory authority to do so, and provided that you been informed by written notice
that the related Furnishing Entity is seeking a protective order or other reasonable assurance for confidential treatment with
respect to the requested Confidential Information, you agree not to disclose the Confidential Information while the Furnishing
Entity’s effort to obtain such a protective order or other reasonable assurance for confidential treatment is pending. You
agree to reasonably cooperate with each Furnishing Entity in its efforts to obtain a protective order or other reasonable assurance
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.

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

You agree promptly
to advise each relevant Furnishing Entity in writing of any misappropriation or unauthorized disclosure or use by any person of

to limit, stop or otherwise remedy such misappropriation, or unauthorized disclosure or use.


 


You acknowledge and
agree 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

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.

your obligations under this Confidentiality Agreement will survive indefinitely.

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

Mortgage Loan (the “Mortgage Loan”) identified by loan number _____ [and loan number [_______]] on the Mortgage
Loan Schedule attached to the Pooling and Servicing Agreement and heretofore secured by the Mortgaged Properties identified on
the Mortgage Loan Schedule by the following names:____________________

         ____________________



 


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 Master 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, of the type
checked below:


 


____ a full defeasance of the entire
principal balance of the Mortgage Loan; or


 


____ a partial defeasance of a portion
of the principal balance of the Mortgage 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 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 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 Master Servicer in accordance with the Servicing Standard)
that the defeasance will not result in an Adverse REMIC Event.


 






    Exhibit U-2


     


    

 


(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.


 


(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 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 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 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 (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 (or the allocated portion thereof in a partial
defeasance) for such year.


 






    Exhibit U-3


     


    

 


(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)       Certify
that it has provided the required notices to, and obtained the required consents of, the related Mortgage Loan Seller in accordance
with Section 3.18(i) of the Pooling and Servicing Agreement.


 


(f)       Agree to provide copies
of all items listed in Exhibit B to you upon request.

IN WITNESS WHEREOF, the Master
Servicer has caused this Notice and Certification to be executed as of the date captioned above.

		II.	Executive Summary



 


Based on the requirements and
qualifications set forth in the Pooling and Servicing Agreement, as well as the items listed below, the Operating Advisor (in accordance
with the Operating Advisor’s analysis requirements outlined in the Pooling and Servicing Agreement) has undertaken a limited
review of the [Special Servicer’s][Fairmount at Brewerytown Special Servicer’s] reported actions on the loans identified

the Operating Advisor believes, in its sole discretion exercised in good faith, that the [Special Servicer][Fairmount at Brewerytown
Special Servicer] [is/is not] operating in compliance with the Servicing Standard with respect to its performance of its duties
under the Pooling and Servicing Agreement during the prior calendar year on a “platform-level basis”. [The Operating

This 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 Pooling and Servicing Agreement,

In addition, the Operating Advisor

[ADD RECOMMENDATION OF REPLACEMENT

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 non-discretionary portions of
net present value calculations and Appraisal Reduction Amount calculations and [LIST OTHER REVIEWED INFORMATION] for the following

		2.	Consulted with the Special Servicer as provided under the Pooling and Servicing Agreement. The Operating
Advisor’s analysis of the Asset Status Reports (including related non-discretionary portions of net present value 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, legal review or legal opinion. 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 and Appraisal Reduction Amount calculations
is limited to the mathematical accuracy of the calculations and the corresponding application of the non-discretionary portions
of the applicable formulas, and as such, does not take into account the reasonableness of the discretionary portions of such formulas.



 


		III.	Specific Items of Review



 


In rendering our assessment herein,
we examined and relied upon the accuracy and completeness of the items listed below:


 


		1.	The Operating Advisor reviewed the following items in connection with the generation of this report:

made
by the Operating Advisor. Such recommendations generally included the following: [LIST].


 


		3.	Appraisal Reduction Amount calculations and non-discretionary portions of net present value calculations.



 


		4.	The Operating Advisor [received/did not receive] information necessary to recalculate and verify
the accuracy of the mathematical calculations and the corresponding application of the non-discretionary portions of the applicable
formulas required to be utilized in connection with any Appraisal Reduction Amount or net present value calculations used in the
special servicer’s determination of what course of action to take in connection with the workout or liquidation of a Specially
Serviced Loan prior to the utilization by the special servicer.



 


		a.	The operating advisor [agrees/does not agree] with the [mathematical calculations] [and/or] [the application of the applicable
non-discretionary portions of the formula] required to be utilized for such calculation.



 


		b.	After consultation with the special servicer to resolve any inaccuracy in the mathematical calculations or the application
of the non-discretionary portions of the related formula in arriving at those mathematical calculations, such inaccuracy [has been/
has not been] resolved.

in this report: [LIST CONCERNS].



 


		6.	In addition to the other information presented herein, the Operating Advisor notes the following
additional items, if any: [LIST ADDITIONAL ITEMS].



 


NOTE: The Operating Advisor’s
review of the above materials should be considered a limited review and not be considered a full or limited audit. For instance,
we did not review each page of the Special Servicer’s policy and procedure manuals (including amendments and appendices),
review underlying lease agreements or similar underlying documents, re-engineer the quantitative aspects of their net present value
calculation, visit any related property, visit the [Special Servicer][Fairmount at Brewerytown Special Servicer], visit the Directing
Certificateholder or interact with any borrower. In addition, our review of the net present value calculations and the corresponding
application of the non-discretionary portions of the applicable formulas, and as such, does not take into account the reasonableness
of the discretionary portions of such formulas.


 


		IV.	Assumptions, Qualifications and Disclaimers Related to the Work Product Undertaken and Opinions
Related to this Report



 


		1.	As provided in the Pooling and Servicing Agreement, the Operating Advisor is not required to report
on instances of non-compliance with, or deviations from, the Servicing Standard or the [Special Servicer’s][Fairmount at
Brewerytown Special Servicer’s] obligations under the Pooling and Servicing Agreement that the Operating Advisor determines,
in its sole discretion exercised in good faith, to be immaterial.



 






    Exhibit V-3


     


    

 


		2.	In rendering our assessment herein, we have assumed that all executed factual statements, instruments,
and other documents that we have relied upon in rendering this
assessment have been executed by persons with legal capacity to execute such documents.



  


		3.	Other than the receipt of any Asset Status Report that is delivered or made available to the Operating
Advisor pursuant to the terms of the Pooling and Servicing Agreement, the Operating Advisor did not participate in, or have access
to, the [Special Servicer’s][Fairmount at Brewerytown Special Servicer’s] and Directing Certificateholder’s discussion(s)
regarding any Specially Serviced Loan. The Operating Advisor does not have authority to speak with the Directing Certificateholder
or borrower directly. As such, the Operating Advisor relied upon the information delivered to it by the [Special Servicer][Fairmount
at Brewerytown Special Servicer] as well as its interaction with the [Special Servicer][Fairmount at Brewerytown 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 to detect fraud or illegal acts should any exist.



 


		4.	The [Special Servicer][Fairmount at Brewerytown Special Servicer] has the legal authority and responsibility
to service any Specially Serviced Loans pursuant to the Pooling and Servicing Agreement. The Operating Advisor has no responsibility
or authority to alter the standards set forth therein or direct the actions of the [Special Servicer][Fairmount at Brewerytown
Special Servicer].



 


		5.	Confidentiality and other contractual limitations limit the Operating Advisor’s ability to
outline the details or substance of any communications 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.



 


		7.	The 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][Fairmount at Brewerytown Special Servicer] as described above. The Operating Advisor does not have a
fiduciary relationship with any Certificateholder



 






    Exhibit V-4


     


    

 


	 	 	or any other party or individual. Nothing is intended to or should be construed
as creating a fiduciary relationship between the Operating Advisor and any Certificateholder, party or individual.

Ladies and Gentlemen:


 


Reference is hereby made to that certain Pooling
and Servicing Agreement dated as of October 1, 2017 (the “Pooling and
Servicing Agreement”), among the UBS Commercial Mortgage Securitization Corp., as Depositor, Wells Fargo Bank,
National Association, as Master Servicer, Rialto Capital Advisors, LLC, as Special Servicer, AEGON USA Realty Advisors, LLC, as
Fairmount at Brewerytown Special Servicer, Wells Fargo Bank, National Association, as Certificate Administrator, Wilmington Trust,
National Association, as Trustee, and Pentalpha Surveillance LLC, as Operating Advisor and as Asset Representations Reviewer. Defined
terms used herein and not otherwise defined shall have the meanings set forth in the Pooling and Servicing Agreement.


 


[Wells Fargo Bank, National Association (“Wells
Fargo”)/Rialto Capital Advisors, LLC (“Rialto Capital”)/AEGON USA Realty Advisors, LLC (“AEGON”)]
understands that [____] (the “Company”) is requesting
certain confidential or non-public information relating to the Mortgage 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 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.


 


[Wells Fargo/Rialto Capital/AEGON] 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 [Wells Fargo/Rialto Capital/AEGON]
by third parties, (b) may not have been verified by [Wells Fargo/Rialto Capital/AEGON], and (c) may be incomplete or contain inaccuracies.
The Company agrees that [Wells Fargo/Rialto Capital/AEGON], the [“Master Servicer”/”Special Servicer”/”Fairmount
at Brewerytown Special Servicer”] (as defined in the Pooling and Servicing Agreement) and its 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) [Wells Fargo/Rialto Capital/AEGON]’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
[Wells Fargo/Rialto Capital/AEGON]; (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 [Wells
Fargo/Rialto Capital/AEGON]; (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 [Wells Fargo/Rialto Capital/AEGON]’s election): (i) responses to reasonable written inquiries received
from the


 



    Exhibit X-2


     


    

 





[_____] [__], 20[__]

Company, (ii) conference calls conducted on a reasonably scheduled basis with [Wells Fargo/Rialto Capital/AEGON]’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”). [Wells
Fargo/Rialto Capital/AEGON] 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) [Wells Fargo/Rialto Capital/AEGON] 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. [Wells Fargo/Rialto Capital/AEGON]
shall cease to provide the Company with Confidential Information if [Wells Fargo/Rialto Capital/AEGON] has actual knowledge that
the Company or its Representatives are affiliates of any borrower under the Mortgage Loan documents and [Wells Fargo/Rialto Capital/AEGON]
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. [Wells Fargo/Rialto Capital/AEGON]’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 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, [Wells Fargo/Rialto Capital/AEGON] 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 [Wells
Fargo/Rialto Capital/AEGON]’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.


 






    Exhibit X-3

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.

ASSET
REVIEW PROCEDURES


 


 


Pursuant
to the terms and subject to the conditions set forth in the Pooling and Servicing Agreement (the “PSA”), the
Asset Representations Reviewer (“Asset Representations Reviewer”) shall perform an Asset Review with respect
to each representation and warranty made by the related Mortgage Loan Seller only with respect to each Delinquent Loan in accordance
with the procedures set forth below (each such procedure, a “Test”); provided, however, the Asset
Representations Reviewer may, but is under no obligation to, modify any Test and/or associated Review Materials described in this
Exhibit PP if, and only to the extent, the Asset Representations Reviewer determines pursuant to the Asset Review Standard
that it is necessary to modify such Test and/or such associated Review Materials in order to facilitate its Asset Review in accordance
with the Asset Review Standard. Capitalized terms used herein but not defined herein have the meaning set forth in the PSA or,
solely with respect to a representation and warranty, the meaning set forth in the related mortgage loan purchase agreement (the
“Mortgage Loan Purchase Agreement”). For the avoidance of doubt, in connection with the performance of the following
Tests:


 


	(A)	With respect to any representation and warranty that includes a knowledge
qualifier (e.g., to the Mortgage Loan Seller’s knowledge, etc.), the Asset Representations Reviewer shall not be responsible
for any investigation or review beyond that set forth in the applicable Test related to such representation and warranty;



 


	(B)	With respect to any representation and warranty that includes the examination
of an insurance policy or Title Policy, the Asset Representations Reviewer will be permitted to engage a qualified consultant to
perform a review of the applicable policy, and will be allowed to rely upon the conclusions of the consultant when making a determination
as to whether there is a Test pass.



 


	(C)	The Asset Representations Reviewer shall be under no duty to provide or obtain a legal opinion,
legal review or legal conclusion;



 


	(D)	Unless otherwise provided in the Test, the “as of” date for the
testing of a representation is as of the Closing Date;



 


	(E)	Unless otherwise provided in the Test, if there is more than one version
of the same document with respect to a particular Mortgage Loan or Mortgaged Property, the document that will be used by the Asset
Representations Reviewer in testing is the document that is dated as of the Closing Date or, if none, the document closest prior
to the Closing Date;



 


	(F)	With respect to each representation and warranty and its related Test(s),
the Asset Representations Reviewer shall take into account any exceptions to such representation and warranty described in the
Mortgage Loan Purchase Agreement with respect to a Mortgage Loan, and a Test pass shall be deemed to have occurred with respect
to such Test if the sole reason for not satisfying the applicable Test is caused by such exception(s);



 


	(G)	Evidence of a failure of a Test could result from (i) an affirmative determination by the Asset Representations Reviewer that
the Test failed to achieve a Test pass, or (ii) a determination by Asset Representations Reviewer that the documentation included
in the Review Materials (after making such request for any missing documents in the manner provided for in the PSA) is not sufficient
to perform the Test; and



 


	(H)	A determination by the Asset Representations Reviewer of a Test pass or a Test failure shall not constitute a determination
by the Asset Representations Reviewer of (i) the existence or nonexistence of a Material



 






    Exhibit PP-1 


     


    

 


	 	Defect, or (ii) whether the Trust should
enforce any rights it may have against the applicable Mortgage Loan Seller.





 


The Asset
Representations Reviewer will only be required to perform the Tests described in this Exhibit PP, and will not be obligated
to perform additional procedures on any Delinquent Loan, even if a different set of procedures or Review Materials could produce
a different outcome. Notwithstanding the required Tests, the Asset Representations Reviewer will not be required to review any
information other than (1) Review Materials specified in the related Test and (2) if applicable, Unsolicited Information. The Asset
Representations Reviewer may, but is under no obligation to, consider Unsolicited Information relevant to the Tests subject to
the terms of the PSA. If the Asset Representations Reviewer considers Unsolicited Information, the Asset Representations Reviewer
shall take into account such Unsolicited Information, in addition to the Review Materials referred to in the applicable Test(s)
procedure when making a determination as to whether there is a Test pass.

	1. Whole Loan; Ownership of Mortgage Loans. Except with respect to a Mortgage Loan that is part of a Whole Loan, each Mortgage Loan is a whole loan and not a participation interest in a Mortgage Loan. At the time of the sale, transfer and assignment to Purchaser, no Mortgage Note or Mortgage was subject to any assignment (other than assignments to Seller), participation or pledge, and Seller had good title to, and was the sole owner of, each Mortgage Loan free and clear of any and all liens, charges, pledges, encumbrances, participations, any other ownership interests on, in or to such Mortgage Loan other than any servicing rights appointment or similar agreement. Seller has full right and authority to sell, assign and transfer each Mortgage Loan, and the assignment to Purchaser constitutes a legal, valid and binding assignment of such Mortgage Loan free and clear of any and all liens, pledges, charges or security interests of any nature encumbering such Mortgage Loan.	1a	Review the amounts listed on the original Mortgage Note and Mortgage for an indication that they match the amounts listed on the Mortgage Loan Schedule. If the amounts are the same, then such Mortgage Loan would be considered a Whole Loan. If there is more than one property then the Mortgage for each Mortgaged Property would need to be aggregated. If identified as such, it will be a Test pass.	Mortgage; Mortgage Note; Loan agreement related to the Mortgage Loan (“Loan Agreement”); Mortgage Loan guaranty; Assignment of Leases; and Environmental Indemnity Agreement (collectively, the “Mortgage Loan Documents”); Mortgage Loan Schedule.
	1b	Review all Asset Status Reports and Final Asset Status Reports to the extent previously prepared by the Special Servicer (collectively referred to in this Exhibit PP as “Collective Asset Status Reports”) for notation of any Mortgage Note or Mortgage that was subject to any assignment (other than assignments to the Seller), participation or pledge, or that the Seller did not have good title to, and was the sole owner of, each Mortgage Loan free and clear of any and all liens, charges, pledges, encumbrances, participations, any other ownership interests on, in or to such Mortgage Loan other than any servicing rights appointment or similar agreement. If no such notation is found, it will be a Test pass.	Collective Asset Status Reports
	1c	Review the Collective Asset Status Reports for notation of any claim or assertion regarding the Seller not having the full right and authority to sell, assign and transfer the Mortgage Loan. If such notation is not found, it will be a Test pass.	Collective Asset Status Reports
	1d	Review the Collective Asset Status Reports for notation of any claim or assertion regarding the assignment to the Purchaser not constituting a legal, valid and binding assignment of such Mortgage Loan free and clear of any and all liens, pledges, charges or security interests of any nature encumbering such Mortgage Loan. If such notation is not found, it will be a Test pass.	Collective Asset Status Reports
	2. Mortgage Loan Document Status. Each related Mortgage Note, Mortgage, Assignment of Leases (if a separate instrument), guaranty and other agreement executed by or on behalf of the related Mortgagor, guarantor or other obligor in connection with such Mortgage Loan is the legal, valid and binding obligation of the related Mortgagor, guarantor or other obligor (subject to any non-recourse provisions contained in any of	2a	Review the opinion of Mortgagor’s counsel (“Mortgagor’s Counsel Opinion”) for an indication that it contains language that the related Mortgage Note, Mortgage, Assignment of Leases (if a separate instrument), guaranty and other agreement executed by or on behalf of the related Mortgagor, guarantor or other obligor in connection with such Mortgage Loan is the legal, valid and	Mortgagor’s Counsel Opinion

        enforcement may be limited by (a) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws
        affecting the enforcement of creditors’ rights generally and (b) general principles of equity (regardless of whether such
        enforcement is considered in a proceeding in equity or at law) and (ii) that certain provisions in such Mortgage Loan documents
        (including, without limitation, provisions requiring the payment of default interest, late fees or prepayment/yield maintenance
        fees, charges and/or premiums) are, or may be, further limited or rendered unenforceable by or under applicable law, but (subject
        to the limitations set forth in clause (i) above) such limitations or unenforceability will not render such Mortgage Loan
        documents invalid as a whole or materially interfere with the Mortgagee’s realization of the principal benefits and/or security
        provided thereby (clauses (i) and (ii) collectively, the “Standard Qualifications”).

         

        Except as set forth in the immediately preceding sentences,

If such indication exists, it will be a Test pass.

If no such notation is found, it will be a Test pass.	Collective Asset Status Reports
	3. Mortgage Provisions. The Mortgage Loan documents for each Mortgage Loan contain provisions that render the rights and remedies of the holder thereof adequate for the practical realization against the Mortgaged Property of the principal benefits of the security intended to be provided thereby, including realization by judicial or, if applicable, nonjudicial foreclosure subject to the limitations set forth in the Standard Qualifications.	3	Review the Mortgage Loan Documents and Mortgagor’s Counsel Opinion for an indication that the Mortgage Loan Documents contain provisions that render the rights and remedies of the holder thereof adequate for the practical realization against the Mortgaged Property of the principal benefits of the security intended to be provided thereby, including realization by judicial or, if applicable, non-judicial foreclosure subject to the limitations set forth in the Standard Qualifications.

Each Mortgaged Property securing a Mortgage Loan is covered by an American Land Title Association loan title insurance policy or a comparable form of loan title insurance policy approved for use in the applicable jurisdiction (or, if such policy is yet to be issued, by a pro forma policy, a preliminary title policy with escrow instructions or a “marked up” commitment, in each case binding on the title insurer) (the “Title Policy”) in the original principal amount of such Mortgage Loan (or with respect to a Mortgage Loan secured by multiple properties, an amount equal to at least the allocated loan amount with respect to the Title Policy for each such property) after all advances of principal (including any advances held in escrow or reserves), that insures for the benefit of the owner of the indebtedness secured by the Mortgage, the first-priority lien of the Mortgage, which lien is subject only to (a) the lien of current real property taxes, water charges, sewer rents and assessments not yet due and payable; (b) covenants, conditions and restrictions, rights of way, easements and other matters of public record; (c) the exceptions (general and specific) and exclusions set forth in such Title Policy; (d) other matters to which like properties are commonly subject; (e) the rights of tenants (as tenants only) under leases (including subleases) pertaining to the related Mortgaged Property and condominium declarations; and (f) if the related Mortgage Loan constitutes a Crossed Mortgage Loan, the lien of the Mortgage for the related Crossed Mortgage Loan or Crossed Mortgage Loans; provided that none of such items (a) through (f), individually or in the aggregate, materially and adversely interfere with the value or current use of the Mortgaged Property, the security intended to be provided by such Mortgage, or the current ability of the related Mortgaged Property to generate net cash flow sufficient to service the related Mortgage Loan, or the Mortgagor’s ability to pay its obligations when they become due (collectively, the “Permitted Encumbrances”). For purposes of clause (a) of the immediately preceding sentence, any such taxes, assessments and other charges shall not be considered due and payable until the date on which interest and/or penalties would be payable thereon. Except as contemplated by clause (f) of the preceding sentence none of the Permitted Encumbrances are mortgage liens that are senior to or coordinate and co-equal with the lien 	6a	Review the Title Policy to determine if it is an American Land Title Association loan title insurance policy or another comparable form of loan title insurance policy approved for use in the applicable jurisdiction.

        An engineering report or property condition assessment was prepared
        in connection with the origination of each Mortgage Loan no more than twelve months prior to the Cut-off Date. To Seller’s
        knowledge, based solely upon due diligence customarily performed in connection with the origination of comparable mortgage loans,
        as of the Closing Date, each related Mortgaged Property was free and clear of any material damage (other than (i) deferred maintenance
        for which escrows were established at origination and (ii) any damage fully covered by insurance) that would affect materially
        and adversely the use or value of such Mortgaged Property as security for the Mortgage Loan.

        16. Insurance. Each related Mortgaged Property is, and
        is required pursuant to the related Mortgage to be, insured by a property insurance policy providing coverage for loss in accordance
        with coverage found under a “special cause of loss form” or “all risk form” that includes replacement cost
        valuation issued by an insurer meeting the requirements of the related Mortgage Loan documents and having a claims-paying or financial
        strength rating of at least “A-:VIII” from A.M. Best Company or “A3” (or the equivalent) from Moody’s
        or “A-” from S&P (collectively the “Insurance Rating Requirements”), in an amount (subject to
        a customary deductible) not less than the lesser of (1) the original principal balance of the Mortgage Loan or Whole Loan, as applicable,
        and (2) the full insurable value on a replacement cost basis of the improvements, furniture, furnishings, fixtures and equipment
        owned by the Mortgagor and included in the Mortgaged Property (with no deduction for physical depreciation), but, in any event,
        not less than the amount necessary, or containing such endorsements as are necessary, to avoid the operation of any coinsurance
        provisions with respect to the related Mortgaged Property.

         

        Each related Mortgaged Property is also covered, and required
        to be covered pursuant to the related Mortgage Loan documents, by business interruption or rental loss insurance which (subject
        to a customary deductible) covers a period of not less than 12 months (or with respect to each Mortgage Loan on a single asset
        with a principal balance of $50 million or more, 18 months).

         

        If any material part of the improvements, exclusive of a parking
        lot, located on a Mortgaged Property is in an area identified in the Federal Register by the Federal Emergency Management Agency
        as having special flood hazards, the related Mortgagor is required to maintain insurance in an amount at least equal to the least
        of (A) the maximum amount available under the National Flood Insurance Program plus any such additional excess flood coverage in

        mortgage loans for securitization, (B) the outstanding principal
        amount of the Mortgage Loan and (C) the insurable value of the Mortgaged Property.

         

        If the Mortgaged Property is located within 25 miles of the
        coast of the Gulf of Mexico or the Atlantic coast of Florida, Georgia, South Carolina or North Carolina, the related Mortgagor
        is required to maintain coverage for windstorm and/or windstorm related perils and/or “named storms” issued by an insurer
        meeting the Insurance Rating Requirements or endorsement covering damage from windstorm and/or windstorm related perils and/or
        named storms by an insurer meeting the Insurance Rating Requirements, in an amount not less than the lesser of (1) the original
        principal balance of the Mortgage Loan and (2) the full insurable value on a replacement cost basis of the improvements, furniture,
        furnishings, fixtures and equipment owned by the Mortgagor and included in the Mortgaged Property (with no deduction for physical
        depreciation), but, in any event, not less than the amount necessary or containing such endorsements as are necessary to avoid
        the operation of any coinsurance provisions with respect to the related Mortgaged Property.

         

        The Mortgaged Property is covered, and required to be covered
        pursuant to the related Mortgage Loan documents, by a commercial general liability insurance policy issued by an insurer meeting
        the Insurance Rating Requirements including coverage for property damage, contractual damage and personal injury (including bodily
        injury and death) in amounts as are generally required by Seller for similar commercial and multifamily loans intended for securitization,
        and in any event not less than $1 million per occurrence and $2 million in the aggregate.

         

        An architectural or engineering consultant has performed an
        analysis of each of the Mortgaged Properties located in seismic zones 3 or 4 in order to evaluate the structural and seismic condition
        of such property, for the sole purpose of assessing the probable maximum loss or scenario expected loss (“PML”)
        for the Mortgaged Property in the event of an earthquake. In such instance, the PML was based on a 475-year return period, an exposure
        period of 50 years and a 10% probability of exceedance. If the resulting report concluded that the PML would exceed 20% of the

        The Mortgage Loan documents require insurance proceeds (or an
        amount equal to such insurance proceeds) in respect of a property loss to be applied either (a) to the repair or restoration of
        all or part of the related Mortgaged Property, with respect to all property losses in excess of 5% of the then outstanding principal
        amount of the related Mortgage Loan or Whole Loan, as applicable, the lender (or a trustee appointed by it) having the right to
        hold and disburse such proceeds as the repair or restoration progresses, or (b) to the payment of the outstanding principal balance
        of such Mortgage Loan or Whole Loan, as applicable, together with any accrued interest thereon.

        name the lender under the Mortgage Loan and its successors and assigns as a loss payee under a mortgagee endorsement clause or,
        in the case of the general liability insurance policy, as named or additional insured. Such insurance policies will inure to the
        benefit of the Trustee. Each related Mortgage Loan obligates the related Mortgagor to maintain all such insurance and, at such
        Mortgagor’s failure to do so, authorizes the lender to maintain such insurance at the Mortgagor’s cost and expense
        and to charge such Mortgagor for related premiums. All such insurance policies (other than commercial liability policies) require
        at least 10 days’ prior notice to the lender of termination or cancellation arising because of nonpayment of a premium and
        at least 30 days prior notice to the lender of termination or cancellation (or such lesser period, not less than 10 days, as may

        Mortgage Loan and (2) a proportionate amount of any lien on real property that is in parity with the Mortgage Loan) after the release
        is not equal to at least 80% of the principal balance of the Mortgage Loan or Whole Loan, as applicable, outstanding after the
        release, the Mortgagor is required to make a payment of principal in an amount not less than the amount required by the REMIC Provisions.

         

        In the case of any Mortgage Loan, in the event of a taking of
        any portion of a Mortgaged Property by a State or any political subdivision or authority thereof, whether by legal proceeding or
        by agreement, the Mortgagor can be required to pay down the principal balance of the Mortgage Loan or Whole Loan, as applicable,
        in an amount not less than the amount required by the loan-to-value ratio and other requirements of the REMIC Provisions and, to
        such extent, condemnation awards may not be required to be applied to the restoration of the Mortgaged Property or released to
        the Mortgagor, if, immediately after the release of such portion of the Mortgaged Property from the lien of the Mortgage (but taking
        into account the planned restoration) the fair market value of the real property constituting the remaining Mortgaged Property
        (reduced by (1) the amount of any lien on the real property that is senior to the Mortgage Loan and (2) a proportionate amount
        of any lien on real property that is in parity with the Mortgage Loan) is not equal to at least 80% of the remaining principal

With respect to each Mortgage Loan over $20 million, and to Seller’s knowledge with respect to each Mortgage Loan of $20 million or less, as of origination, the related special-form all-risk insurance policy and business interruption policy (issued by an insurer meeting the Insurance Rating Requirements) do not specifically exclude Acts of Terrorism, as defined in the Terrorism Risk Insurance Act of 2002, as amended by the Terrorism Risk Insurance Program Reauthorization Act of 2007 and the Terrorism Risk Insurance Program Reauthorization Act of 2015 (collectively referred to as “TRIA”), from coverage, or if such coverage is excluded, it is covered by a separate terrorism insurance policy. With respect to each Mortgage Loan, the related Mortgage Loan documents do not expressly waive or prohibit the Mortgagee from requiring coverage for Acts of Terrorism, as defined in TRIA, or damages related thereto except to the extent that any right to require such coverage may be limited by commercial availability on commercially reasonable terms; provided that if TRIA or a similar or subsequent statute is not in effect, then, provided that terrorism insurance is commercially available, the Mortgagor under each Mortgage Loan is required to carry terrorism 	29a	Review the Mortgage Loan Documents to determine if the original principal balance was greater than $20 million.

Subject to specific exceptions set forth below, each Mortgage Loan contains a “due-on-sale” or other such provision for the acceleration of the payment of the unpaid principal balance of such Mortgage Loan if, without the consent of the holder of the Mortgage (which consent, in some cases, may not be unreasonably withheld) and/or complying with the requirements of the related Mortgage Loan documents (which provide for transfers without the consent of the lender which are customarily acceptable to Seller lending on the security of property comparable to the related Mortgaged Property, including, without limitation, transfers of worn-out or obsolete furnishings, fixtures, or equipment promptly replaced with property of equivalent value and functionality and transfers by leases entered into in accordance with the Mortgage Loan documents), (a) the related Mortgaged Property, or any equity interest of greater than 50% in the related Mortgagor, is directly or indirectly pledged, transferred or sold, other than as related to (i) family and estate planning transfers or transfers upon death or legal incapacity, (ii) transfers to certain affiliates as defined in the related Mortgage Loan documents, (iii) transfers of less than, or other than, a controlling interest in the related Mortgagor, (iv) transfers to another holder of direct or indirect equity in the Mortgagor, a specific Person designated in the related Mortgage Loan documents or a Person satisfying specific criteria identified in the related Mortgage Loan documents, such as a qualified equityholder, (v) transfers of stock or similar equity units in publicly traded companies or (vi) a substitution or release of collateral within the parameters of representations and warranties 27 and 32 herein or the 	30a	Review the Mortgage Loan Documents for “due-on-sale” or other such provisions for the acceleration of the payment of the unpaid principal balance of such Mortgage Loan in the circumstances described in the first sentence of representation and warranty 30.

	31. Single-Purpose Entity. The Mortgage Loan documents require the Mortgagor to be a Single-Purpose Entity for at least as long as the Mortgage Loan is outstanding. Both the Mortgage Loan documents and the organizational documents of the Mortgagor with respect to each Mortgage Loan with a Cut-off Date Balance in excess of $5 million provide that the Mortgagor is a Single-Purpose Entity, and each Mortgage Loan with a Cut-off Date Balance of $30 million or more has a counsel’s opinion regarding non-consolidation of the Mortgagor. For this purpose, a “Single-Purpose Entity” shall mean an entity, other than an individual, whose organizational documents (or if the Mortgage Loan has a Cut-off Date Balance equal to $5 million or less, its organizational documents or the related Mortgage Loan documents) provide substantially to the effect that it was formed or organized solely for the purpose of owning and operating one or more of the Mortgaged Properties securing the Mortgage Loans and prohibit it from engaging in any business unrelated to such Mortgaged Property or Mortgaged Properties, and whose organizational documents further provide, or which entity represented in the related Mortgage Loan documents, substantially to the effect that it does not have any assets other than those related to its interest in and operation of such Mortgaged Property or Mortgaged Properties, or any indebtedness other 	31a	Review the Mortgage Loan Documents for provisions that require that the Mortgagor to be a Single-Purpose Entity (as defined in representation and warranty 31) for at least as long as any Mortgage Loan is outstanding.

	32. Defeasance. With respect to any Mortgage Loan that, pursuant to the Mortgage Loan documents, can be defeased (a “Defeasance”), (i) the Mortgage Loan documents provide for Defeasance as a unilateral right of the Mortgagor, subject to satisfaction of conditions specified in the Mortgage Loan documents; (ii) the Mortgage Loan cannot be defeased within two years after the Closing Date; (iii) the Mortgagor is permitted to pledge only United States “government securities” within the meaning of Section 1.860G-2(a)(8)(ii) of the Treasury Regulations, the revenues from which will, in the case of a full Defeasance, be sufficient to make all scheduled payments under the Mortgage Loan when due, including the entire remaining principal balance on the maturity date (or on or after the first date on which payment may be made without payment of a yield maintenance charge or prepayment penalty) or, if the Mortgage Loan is an ARD Loan, the entire principal balance outstanding on the Anticipated Repayment Date (or on or after the first date on which payment may be made without payment of a yield maintenance charge or prepayment penalty), and if the Mortgage Loan permits partial releases of real property in connection with partial Defeasance, the revenues from the collateral will be sufficient to pay all such scheduled payments calculated on a principal amount equal to a specified percentage at least equal to the lesser of (a) 110% of the allocated loan amount for the real property to be released and (b) the outstanding principal balance of the Mortgage Loan or Whole Loan, as applicable; (iv) the defeasance collateral is not permitted to be subject to prepayment, call, or early redemption that results in revenues from such collateral that are insufficient to pay all applicable payments described in clause (iii) above; (v) the Mortgagor is required to provide a certification from an independent certified public accountant that the defeasance collateral is sufficient to make all applicable payments described in clause (iii) above; (vi) if the Mortgagor would continue to own assets in addition to the defeasance collateral, the portion of the Mortgage Loan secured by defeasance collateral is required to be assumed (or the Mortgagee may require such assumption) by a Single-Purpose Entity; (vii) the Mortgagor is required to provide an opinion of counsel 	32	Review the Mortgage Loan Documents for provisions allowing the Mortgage Loan to be defeased, and if so, whether such Mortgage Loan Documents contain the provisions described in clauses (i) through (viii) of representation and warranty 32.

        34. Ground Leases. For purposes of these representations
        and warranties, a “Ground Lease” shall mean a lease creating a leasehold estate in real property where the fee
        owner as the ground lessor conveys for a term or terms of years its entire interest in the land (or, with respect to air rights
        leases, the air) and buildings and other improvements, if any, comprising the premises demised under such lease to the ground lessee
        (who may, in certain circumstances, own the building and improvements on the land), subject to the reversionary interest of the
        ground lessor as fee owner and does not include industrial development agency or similar leases for purposes of conferring a tax
        abatement or other benefit.

         

        With respect to any Mortgage Loan where the Mortgage Loan is
        secured by a leasehold estate under a Ground Lease in whole or in part, and the related Mortgage does not also encumber the related
        lessor’s fee interest in such Mortgaged Property, based upon the terms of the Ground Lease and any estoppel or other agreement
        received from the ground lessor in favor of Seller, its successors and assigns, Seller represents and warrants that:

         

        (a)       The Ground Lease
        or a memorandum regarding such Ground Lease has been duly recorded or submitted for recordation in a form that is acceptable for
        recording in the applicable jurisdiction. The Ground Lease or an estoppel or other agreement received from the ground lessor permits
        the interest of the lessee to be encumbered by the related Mortgage and does not restrict the use of the related Mortgaged Property
        by such lessee, its successors or assigns in a manner that would materially adversely affect the security provided by the related

        has an original term (or an original term plus one or more optional renewal terms, which, under all circumstances, may be exercised,
        and will be enforceable, by either Mortgagor or the Mortgagee) that extends not less than 20 years beyond the stated maturity of
        the related Mortgage Loan, or 10 years past the stated maturity if such Mortgage Loan fully amortizes by the stated maturity (or
        with respect to a Mortgage Loan that accrues on an actual 360 basis, substantially amortizes);

         

        (d)       The Ground Lease
        either (i) is not subject to any liens or encumbrances superior to, or of equal priority with, the Mortgage, except for the related
        fee interest of the ground lessor and the Permitted Encumbrances, or (ii) is subject to a subordination, non-disturbance and attornment
        agreement to which the Mortgagee on the lessor’s fee interest in the Mortgaged Property is subject;

        (f)       Seller has not
        received any written notice of material default under or notice of termination of such Ground Lease. To Seller’s knowledge,
        there is no material default under such Ground Lease and no condition that, but for the passage of time or giving of notice, would
        result in a material default under the terms of such Ground Lease and to Seller’s knowledge, such Ground Lease is in full
        force and effect as of the Closing Date;

         

        (g)       The Ground Lease
        or ancillary agreement between the lessor and the lessee requires the lessor to give to the lender written notice of any default,
