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 separate real estate mortgage investment conduits (the “Upper-Tier REMIC”
and the “Lower-Tier REMIC”). In addition, three separate REMIC elections were designated to be made with respect
to three mortgage loans, any REO Property with respect thereto and the proceeds thereof for federal income tax purposes pursuant
to a REMIC Declaration dated as of January 26, 2021 (the “Westchester Loan REMIC Declaration”), and such REMIC
the “Westchester Loan REMIC”), a REMIC Declaration dated as of March 4, 2021 (the “Voyant Loan REMIC
Declaration”, and such REMIC the “Voyant Loan REMIC”) and a REMIC Declaration dated as of February
12, 2021 (the “MGM Grand & Mandalay Bay Loan REMIC Declaration”, and such REMIC the “MGM Grand
& Mandalay Bay Loan REMIC”, and each, a “REMIC Declaration”). The Certificate Administrator shall
make a REMIC election with respect to the Westchester Loan REMIC and the Voyant Loan REMIC as described herein. The Westchester
Loan REMIC and the Voyant Loan REMIC will be designated as the “Serviced Loan REMICs”, and together with the
MGM Grand & Mandalay Bay Loan REMIC, the “Loan REMICs”. The Westchester Loan REMIC, the Voyant Loan REMIC,
the Upper-Tier REMIC and the Lower-Tier REMIC will be designated as the “Trust REMICs”.


 


In
addition, the parties intend that the portion of the Trust Fund consisting of the Class Z Specific Grantor Trust Assets and
distributions thereon and the residual interests issued by the Serviced Loan REMICs, shall be treated as a grantor trust (the
“Grantor Trust”) for federal income tax purposes under subpart E, part I of subchapter J of the Code. The Class Z
Certificates will represent undivided beneficial interests in the related portions of the Trust Fund consisting of the Class Z
Specific Grantor Trust Assets and the Class R Certificates will represent beneficial ownership of the residual interests
issued by the Serviced Loan REMICs. As provided herein, the Certificate Administrator shall take all actions expressly required
hereunder to ensure that the portion of the Trust Fund consisting of the Grantor Trust maintains its status as a grantor trust
under federal income tax law and not be treated as part of the Trust REMICs.


 


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

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


 


“Nonrecoverable
P&I Advance”: Any P&I Advance previously made or proposed to be made in respect of a Mortgage Loan (including
any Non-Serviced Mortgage Loan) or REO Mortgage Loan, which the Master Servicer, in accordance with the Servicing Standard, or
the Trustee, in its good faith business judgment, as applicable, determines would not be ultimately recoverable, together with
any accrued and unpaid interest thereon at the Reimbursement Rate, from Late Collections or any other recovery on or in respect
of such Mortgage Loan or REO Mortgage Loan; provided, however, that the Special Servicer may, at its option (with
respect to any Specially Serviced Loan other than an Excluded Special Servicer Loan), 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), the Certificate Administrator,
the Trustee, the Operating Advisor and the 17g-5 Information Provider notice of such determination. Any such determination by
the Master Servicer, the Special Servicer or the Trustee may be conclusively relied upon by, and shall be binding upon, the Master
Servicer and the Trustee, provided, however, that the Special Servicer shall not have such obligation to make an
affirmative determination that any P&I Advance is or would be recoverable and in the absence of a determination by the Special
Servicer that such P&I Advance is or would be a Nonrecoverable P&I Advance, such decision shall remain with the Master
Servicer or Trustee, as applicable. If the Special Servicer makes a determination that only a portion, and not all, of any previously
made or proposed P&I Advance is a Nonrecoverable P&I Advance, the Master Servicer and the Trustee may make its own subsequent
determination that any remaining portion of any such previously made or proposed P&I Advance is a Nonrecoverable P&I Advance.


 


With
respect to any Non-Serviced Whole Loan, if any Non-Serviced Master Servicer or Non-Serviced Special Servicer, as applicable, in
connection with a securitization of the related Non-Serviced Companion Loan determines that a principal and interest advance with
respect to the related Non-Serviced Companion Loan, if made, would be a “nonrecoverable P&I advance”, such determination
shall not be binding on the Master Servicer and the Trustee as it


 






    -78-


     


    

 


relates to any proposed P&I Advance with respect to the
related Non-Serviced Mortgage Loan. Similarly, with respect to the related Non-Serviced Mortgage Loan, if the Master Servicer,
the Special Servicer or the Trustee, as applicable, determines that any P&I Advance with respect to a related Non-Serviced
Mortgage Loan, if made, would be a Nonrecoverable P&I Advance, such determination shall not be binding on the related Non-Serviced
Master Servicer and related Non-Serviced Trustee as it relates to any proposed P&I Advance with respect to the related Non-Serviced
Companion Loan (unless the related Non-Serviced PSA provides otherwise).


 


In
making such recoverability determination, the Master Servicer, the Special Servicer or the Trustee, as applicable, will be entitled
(a) to consider (among other things) (i) the obligations of the Mortgagor under the terms of the related Mortgage Loan
or Companion Loan as it may have been modified and (ii) the related Mortgaged Properties in their “as-is” or
then-current conditions and occupancies, as modified by such party’s assumptions (consistent with the Servicing Standard
in the case of the Master Servicer or the Special Servicer or in its good faith business judgment in the case of the Trustee,
solely in its capacity as Trustee) regarding the possibility and effects of future adverse changes with respect to such Mortgaged
Properties, (b) to estimate and consider (among other things) future expenses, (c) to estimate and consider (consistent
with the Servicing Standard in the case of the Master Servicer and the Special Servicer or in its good faith business judgment
in the case of the Trustee, solely in its capacity as Trustee) (among other things) the timing of recoveries, and (d) to
give due regard to the existence of any Nonrecoverable Advances which, at the time of such consideration, the recovery of which
are being deferred or delayed by the Master Servicer or the Trustee because there is insufficient principal available for such
recovery, in light of the fact that related proceeds are a source of recovery not only for the Advance under consideration but
also a potential source of recovery for such delayed or deferred Advance.


 


In
addition, any Person, in considering whether a P&I Advance is a Nonrecoverable Advance, will be entitled to give due regard
to the existence of any outstanding Nonrecoverable Advance or Workout-Delayed Reimbursement Amount with respect to other Mortgage
Loans, the reimbursement of which, at the time of such consideration, is being deferred or delayed by the Master Servicer or the
Trustee because there is insufficient principal available for such reimbursement, in light of the fact that proceeds on the related
Mortgage Loan are a source of reimbursement not only for the P&I Advance under consideration, but also as a potential source
of reimbursement of such Nonrecoverable Advance or Workout-Delayed Reimbursement Amounts which are or may be being deferred or
delayed. In addition, any such Person may update or change its recoverability determinations at any time (but not reverse any
other Person’s determination that an Advance is a Nonrecoverable Advance) and, consistent with the Servicing Standard, in

The
determination by the Master Servicer, the Special Servicer or the Trustee, as applicable, that the Master Servicer or the Trustee,
as applicable, has made a Nonrecoverable P&I Advance or that any proposed P&I Advance, if made, would constitute a Nonrecoverable
P&I Advance, or any updated or changed recoverability determination, shall be evidenced by an Officer’s Certificate
delivered by either the Special Servicer or the Master Servicer to the other and to the Trustee, the Certificate Administrator
and the Directing Certificateholder (but in the case of the Directing Certificateholder, only if no Consultation Termination Event
is continuing and other than with respect to an Excluded Loan as to such party) (and, in the case of a Serviced Mortgage Loan
or Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced Master Servicer, as applicable), the Operating Advisor (but
only in the case of the Special Servicer), the Depositor, or by the Trustee to the Depositor, the Master Servicer, the Special

or Non-Serviced Master Servicer, as applicable) and the Certificate Administrator. 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, income and expense
statements, rent rolls, occupancy status, property inspections and any other information used by the Master Servicer, the Special

Loan, or the related Mortgaged Property).

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


 






    -80-


     


    

 


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 (and, upon the reasonable request by the Trustee, Master Servicer or Special Servicer, as applicable,
the Master Servicer and the Special Servicer shall deliver any relevant Appraisals or market value estimates in its possession
to the requesting party for such purpose). Absent bad faith, the Master Servicer’s, 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 it has made a Nonrecoverable
Servicing Advance or that any proposed Servicing Advance, if made, would constitute a Nonrecoverable Servicing Advance, or any
updated or changed recoverability determination, shall be evidenced by an Officer’s Certificate delivered by either of the
Special Servicer or the Master Servicer to the other and to the Trustee, the Certificate Administrator, the Directing Certificateholder
(but in the case of the Directing Certificateholder, only if no Consultation Termination Event is continuing and other than with
respect to an Excluded Loan as to such party) (and in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any
Other Servicer or Non-Serviced Master Servicer, as applicable), the Operating Advisor (but only in the case of the Special Servicer)
and the Depositor, or by the Trustee to the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and the
Certificate Administrator (and in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced
Master Servicer, as applicable); provided, however, that the Special Servicer may, at its option, make a determination
in accordance with the Servicing Standard, that any Servicing Advance previously made or proposed to be made is a Nonrecoverable
Servicing Advance and shall deliver to the Master Servicer (and with respect to a Serviced Mortgage Loan, to any Other Servicer),
the Trustee, the Operating Advisor, the Certificate Administrator and the 17g-5 Information Provider notice of such determination.
Any such determination by the Master Servicer, the Special Servicer or the Trustee may be conclusively relied upon by, and shall
be binding upon, the Master Servicer and the Trustee, provided, however, that the Special Servicer shall not have
such obligation to make an affirmative determination that any 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.


 






    -81-


     


    

 


The Officer’s Certificate shall
set forth such determination of nonrecoverability and the considerations of the Master Servicer, the Special Servicer or the Trustee,
as applicable, forming the basis of such determination (which shall be accompanied by, to the extent available, related income
and expense statements, rent rolls, occupancy status and property inspections, and shall include any existing Appraisal with respect
to the related Mortgage Loan or Serviced Companion Loan, as applicable, or related Mortgaged Property). The Special Servicer shall
promptly furnish 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. 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 Crossed Underlying Loan (if any), such
recoverability determination shall take into account the cross-collateralization of the related Crossed Mortgage Loan Group. The
determination as to the recoverability of any servicing advance previously made or proposed to be made in respect of a Non-Serviced
Whole Loan shall be made by the related Non-Serviced Master Servicer, Non-Serviced Special Servicer or Non-Serviced Trustee, as
the case may be, pursuant to the Non-Serviced PSA.

lender (and with respect to any Serviced AB Whole Loan, taking into account the subordinate nature of such Subordinate Companion
Loan(s))), and the Master Servicer or the Special Servicer, as applicable, has made a reasonable effort to contact the nonresponsive
party, it may take such action without waiting for a response from such nonresponsive party; provided that the Special

respect to each Whole Loan, in the event of a conflict between this Agreement and the related Intercreditor Agreement, the related
Intercreditor Agreement controls; provided that in no event shall the Master Servicer or the Special Servicer 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.

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 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 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) and clause (f) of the
final proviso to the definition of “Mortgage File” herein.


 


If,
in accordance with the related Mortgage Loan Purchase Agreement and consistent with Section 2.01(c), 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


 






    -129-


     


    

 


the Trustee referred to in clause (iii), clause (v) (to the extent not already assigned pursuant
to clause (iii)) or clause (x) of the definition of “Mortgage File”, 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).


 


Notwithstanding
anything herein to the contrary, with respect to letters of credit referred to in clause (xii) of the definition of
“Mortgage File” and relating to a Serviced Mortgage Loan, the applicable Mortgage Loan Seller shall deliver the original
to the Master Servicer (which letter of credit shall be titled in the name of, or assigned to, “Midland Loan Services, a
Division of PNC Bank, National Association, as Master Servicer, on behalf of Wells Fargo Bank, National Association, as Trustee,
for the benefit of registered holders of CSAIL 2021-C20 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates,
Series 2021-C20”, and a copy to the Custodian or, if such original has been submitted by the applicable Mortgage Loan Seller
to the issuing bank to effect a reissuance, assignment or amendment of such letter of credit (changing the beneficiary thereof
to the Master Servicer (in care of the Trustee, as titled above) that may be required in order for the Master Servicer to draw
on such letter of credit on behalf of the Trust in accordance with the applicable terms thereof and/or of the related Mortgage
Loan documents, as applicable) and 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 with respect to any letter(s)
of credit a copy thereof to the Custodian together with an officer’s certificate of the applicable Mortgage Loan Seller
certifying that such document has been delivered to the issuing bank for reissuance or an Officer’s Certificate from the
Master Servicer certifying that it holds the letter(s) of credit pursuant to this Section 2.01(b), one of which shall
be delivered to the Custodian on the Closing Date. If a letter of credit referred to in the previous sentence 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 the appropriate
assignment or amendment documents (or copies of such assignment or amendment documents if the related Mortgage Loan Seller has
submitted the originals to the related issuer of such letter of credit for processing) to the Custodian within thirty (30) days
of the Closing Date. If not otherwise paid by the related Mortgagor, the applicable Mortgage Loan Seller shall pay any costs of
assignment or amendment of such letter(s) of credit required in order for the Master Servicer to draw on such letter(s) of credit
on behalf of the Trust 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 assigned or amended in order that it may be
drawn by the Master Servicer on behalf of the Trust.


 


(c)            
Pursuant to each Mortgage Loan Purchase Agreement, except in the case of a Non-Serviced Mortgage Loan, the related Mortgage Loan
Seller is required at its sole cost and expense, to itself, or to engage a third party to, put each Assignment of Mortgage, each
assignment of Assignment of Leases and each assignment of each UCC Financing Statement (collectively, the “Assignments”
and, individually, “Assignment”) relating to the Mortgage Loans conveyed by it


 






    -130-


     


    

 


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


 






    -131-


     


    

 


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


 


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


 


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


 


(g)            
With respect to the Mortgage Loan secured by the Mortgaged Property identified as SpringHill Suites Boise on the Mortgage Loan Schedule,
which is subject to a franchise agreement with a related comfort letter in favor of the respective Mortgage Loan Seller that requires
notice to or request of the related franchisor to transfer or assign any related comfort letter to the Trust or otherwise have
a new comfort letter issued in the name of the Trust, the related Mortgage Loan Seller or its designee will be required to provide
any such required notice or make any such required request to the related franchisor (with a copy of such notice or request to
the Master Servicer) within 45 days of the Closing Date (or any shorter period if required by the applicable comfort letter),
and the Master Servicer shall use reasonable efforts in accordance with the Servicing Standard to acquire such replacement comfort
letter, if necessary (or to acquire any such new document or acknowledgement as may be contemplated under the existing comfort


 






    -132-


     


    

 


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


 


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


 


(j)             
Notwithstanding anything to the contrary contained in this Section 2.01 or in Section 2.02, in connection
with a Servicing Shift Whole Loan, (1) instruments of assignment to the Trustee may be in blank and need not be recorded pursuant
to this Agreement (other than the endorsements to the Mortgage Note(s) evidencing the related Servicing Shift Mortgage Loan) until
the earlier of (i) the related Servicing Shift Securitization Date, in which case such instruments shall be assigned and recorded
in accordance with the related Non-Serviced PSA, (ii) 180 days following the Closing Date, and (iii) such Servicing Shift Whole
Loan becoming a Specially Serviced Loan prior to such Servicing Shift Securitization Date, in which case assignments and recordations
shall be effected in accordance with this Section 2.01 until the occurrence, if any, of such Servicing Shift Securitization
Date, (2) no letter of credit need be amended (including, without limitation, to change the beneficiary thereon) until the earlier
of (i) the related Servicing Shift Securitization Date, in which case such amendment shall be in accordance with the related Non-Serviced
PSA, (ii) 180 days following the Closing Date, and (iii) such Servicing Shift Whole Loan becoming a Specially Serviced Loan prior
to such Servicing Shift Securitization Date in which case such amendment shall be effected in accordance with the terms of this
Section 2.01, and (3) on and following such Servicing Shift Securitization Date, the Person selling the related Servicing
Shift Lead Note to the related Non-Serviced Depositor, at its own expense, shall be (a) entitled to direct in writing, via a Request
for Release, which may be conclusively relied upon by the Custodian, the Custodian to deliver the originals of all the Mortgage
Loan documents relating to such Servicing Shift Whole Loan in its possession (other than the original Mortgage Note(s) evidencing
such Servicing Shift Mortgage Loan) to the related Non-Serviced Trustee or the related Non-Serviced Custodian, (b) if the right
under clause (a) is exercised, required to cause the retention by or delivery to the Custodian of photocopies of


 






    -133-


     


    

 


Mortgage
Loan documents related to such Servicing Shift Whole Loan so delivered to such Non-Serviced Trustee or such Non-Serviced Custodian,
(c) entitled to cause the completion (or, in the event of a recordation as contemplated by clause (1)(ii) of this paragraph,
the preparation, execution and delivery) and recordation of instruments of assignment in the name of the related Other Trustee
or related Non-Serviced Custodian, (d) if the right under clause (c) is exercised, required to deliver to the Trustee or
Custodian photocopies of any instruments of assignment so completed and recorded, and (e) entitled to require the Master Servicer
to transfer, and to cooperate with all reasonable requests in connection with the transfer of, the Servicing File, and any Escrow
Payments, reserve funds and items specified in clauses (x) and (xii) of the definition of “Mortgage File”
for such Servicing Shift Whole Loan to the related Other Servicer.


 


(k)            
Notwithstanding anything to the contrary contained herein, with respect to a Joint Mortgage Loan, the obligations of each of the
applicable Mortgage Loan Sellers to deliver a Mortgage Note (and any related allonge or assignment) to the Custodian shall be
limited to delivery of only the Mortgage Note (and any related allonge or assignment) held by such party to the Custodian. With
respect to a Joint Mortgage Loan, the obligations of the applicable Mortgage Loan Sellers to deliver the remaining portion of
the related Mortgage File or any document required to be delivered with respect thereto shall be joint and several, provided that
either of the applicable Mortgage Loan Sellers may deliver one Mortgage File or one of any other document required to be delivered
with respect to such Mortgage Loan hereunder and such delivery shall satisfy such delivery requirements for each of the applicable
Mortgage Loan Sellers.


 


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


 


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


 






    -134-


     


    

 


is continuing and other than with respect to any Excluded Loan as to such party), the Operating
Advisor, the Asset Representations Reviewer and the applicable Mortgage Loan Seller (as to each Mortgage Loan listed in the Mortgage
Loan Schedule) that, except as specifically identified in any exception report annexed to such writing (the “Custodial
Exception Report”), (i) subject to the final proviso of the definition of “Mortgage File” and Section 2.01,
all documents specified in clauses (i) through (v), (viii), (ix), (xi), (xii) and
(xiii) (or, with respect to clause (xii), a copy of such letter of credit and the required Officer’s Certificate),
if any, of the definition of “Mortgage File”, as applicable, are in its possession, (ii) the foregoing documents
delivered or caused to be delivered by the Mortgage Loan Sellers have been reviewed by the Custodian and appear regular on their
face and appear to be executed and to relate to such Mortgage Loan, and (iii) based on such examination and only as to the
foregoing documents, the information set forth in the Mortgage Loan Schedule with respect to the items specified in clauses (iv),
(viii) and (x) in the definition 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 of Exhibit Q, certify in writing to each of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Directing Holder (so long as no Consultation
Termination Event is continuing and other than with respect to any Excluded Loan as to such party), the Operating Advisor, the
Asset Representations Reviewer 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 final proviso of the definition of “Mortgage
File” 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 and
(iii) based on such examination and only as to the foregoing documents, the information set forth in the Mortgage Loan Schedule
with respect to the items specified in clauses (iv), (viii) and (x) 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 Holder, in its sole judgment, may (other than with respect to any Excluded Loan as to such
party and, with respect to any other Mortgage Loan, only if no Control Termination Event is continuing), and the Special Servicer
may, in accordance with the Servicing Standard, during a Control Termination Event, permit the related Mortgage Loan Seller


 






    -135-


     


    

 


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 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 6 of the related Mortgage
Loan Purchase Agreement; provided, however, that such Mortgage Loan Seller is not 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 if 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 (xvii) of the definition
of “Mortgage File” exist or are required to be delivered by the Depositor, the Mortgage Loan Sellers or any other
Person or (ii) to inspect, review or examine any of the documents, instruments, certificates or other papers relating to
the Mortgage Loans delivered to it to determine that the same are genuine, enforceable, duly authorized, sufficient to perfect
and maintain the perfection of a security interest or appropriate for


 






    -136-


     


    

 


the represented purpose or that they are other than what
they purport to be on their face and, with respect to the documents specified in clause (viii) of the definition of
the “Mortgage File”, whether the insurance is effective as of the date of the recordation, whether all endorsements
or riders issued are included in the file or if the policy has not been issued whether any acceptable replacement document has
been dated the date of the related Mortgage Loan funding. Further, with respect to the UCC Financing Statements referenced in
the Mortgage File, absent actual knowledge to the contrary or copies of UCC Financing Statements delivered to the Custodian as
part of the Mortgage File indicating otherwise, the Custodian may assume, for the purposes of the filings and the certification
to be delivered in accordance with this Section 2.02 that the related Mortgage File should include one state level
UCC Financing Statement filing for each Mortgaged Property (or with respect to any Mortgage Loan that has two or more Mortgagors,
for each Mortgagor, except to the extent multiple Mortgagors are named as debtors in the same UCC Financing Statement filing),
or if the Custodian has received notice that a particular UCC Financing Statement was filed as a fixture filing, that the related
Mortgage File should include only a local UCC Financing Statement filing for each Mortgaged Property (or with respect to any Mortgage
Loan that has two or more Mortgagors, for each Mortgagor, except to the extent multiple Mortgagors are named as debtors in the
same UCC Financing Statement filing). The assignments of the UCC Financing Statements to be assigned to the Trust will be delivered
on the new national forms (or on such other form as may be acceptable for filing or recording in the applicable jurisdiction)
and in a format suitable for filing or recording, as applicable, and will be filed or recorded in the jurisdiction(s) where such
UCC Financing Statements were originally filed or recorded, as indicated in the documents provided, and in accordance with then-current
laws.


 


(f)             
If, in the process of reviewing the Mortgage Files or at any time thereafter, the Custodian finds any document or documents constituting
a part of a Mortgage File (1) not to have been properly executed, (2) subject to the timing requirements of Sections 2.01(b)
and 2.01(c), not to have been delivered, (3) to contain information that does not conform in any material respect
with the corresponding information set forth in the Mortgage Loan Schedule or (4) to be defective on its face (each, a “Defect”
in the related Mortgage File), the Custodian shall promptly so notify the Depositor, the Trustee, the Master Servicer, the Special
Servicer, the Certificate Administrator, the Directing Holder, the applicable Mortgage Loan Seller (and in no event later than
ninety (90) days after the Closing Date and every calendar quarter thereafter until all Defects are corrected) by providing a
Custodial Exception Report setting forth for each affected Mortgage Loan, with particularity, the nature of such Defect (in a
form reasonably acceptable to the Custodian and such Mortgage Loan Seller and separating items required to be in the Mortgage
File but never delivered from items which were delivered by such Mortgage Loan Seller but are out for recording or filing and
have not been returned by the recorder’s office or filing office).


 


(g)            
If the Master Servicer or the Special Servicer (i) receives any request or demand for repurchase or replacement of a Mortgage
Loan because of a breach of or alleged breach of a representation or warranty or a Defect (any such request or demand for repurchase
or replacement, a “Repurchase Request”, and the Master Servicer or the Special Servicer, as applicable, to
the extent it receives a Repurchase Request, the “Repurchase Request Recipient” with respect to such Repurchase
Request); or (ii) receives any withdrawal of a Repurchase Request by the Person making such Repurchase Request or any rejection
of a Repurchase Request (or such a Repurchase Request is forwarded to the Master Servicer or the Special Servicer by another party
hereto), then the Repurchase Request Recipient shall deliver notice (which may be by electronic


 






    -137-


     


    

 


format so long as a “backup”
hard copy of such notice is also delivered on or prior to the next Business Day) of such Repurchase Request or withdrawal or rejection
of a Repurchase Request (each, a “15Ga-1 Notice”) to the applicable Mortgage Loan Seller (other than in the
case of a rejection by such Mortgage Loan Seller) and the Depositor, in each case within ten (10) Business Days from such Repurchase
Request Recipient’s receipt thereof.


 


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


 


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


 


If
the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian
receives a Repurchase Request, such party shall promptly forward or otherwise provide written notice of such Repurchase Request
to the Master Servicer, if relating to a Non-Specially Serviced Loan, or to the Special Servicer, if relating to a Specially Serviced
Loan or REO Property, and include the following statement in the related correspondence: “This is a ‘Repurchase Request’
under Section 2.02 of the Pooling and Servicing Agreement relating to the CSAIL 2021-C20 Commercial Mortgage Trust,
Commercial Mortgage Pass-Through Certificates, Series 2021-C20 requiring action by you as the ‘Repurchase Request Recipient’
thereunder.” Upon receipt of such Repurchase Request by the Master Servicer or the Special Servicer, as applicable, such
party shall be deemed to be the Repurchase Request Recipient in respect of such Repurchase Request, and such party shall comply
with the procedures set forth in this Section 2.02(g) with respect to such Repurchase Request. In no event shall the
Custodian, by virtue of this provision, be required to provide any notice other than as set forth in Section 2.02
in connection with its review of the Mortgage File.


 


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

Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian shall
also be provided to the Depositor and, in the case of a withdrawal notice, to the applicable Mortgage Loan Seller.


 


If
a Mortgage Loan is repurchased or replaced pursuant to Section 2.03, the Master Servicer (with respect to Non-Specially
Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) shall promptly notify the Depositor of such
repurchase or replacement.

(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

of the Mortgage Loans or the ability of the Depositor to carry out the transactions contemplated by this Agreement; and


 






    -139-


     


    

 


(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)           
If any Certificateholder, the Directing Holder, the Master Servicer, the Special Servicer, the Certificate Administrator, Operating
Advisor (solely in its capacity as Operating Advisor) or the Trustee discovers (without implying any duty of such person to make,
or to attempt to make, such a discovery) or receives notice alleging a Material Defect in any Mortgage File, such Certificateholder,
the Directing Holder, the Master Servicer, the Special Servicer, the Trustee, Operating Advisor (solely in its capacity as Operating
Advisor) or the Certificate Administrator, as applicable, shall give prompt written notice of such Material Defect to the Depositor,
the Master Servicer, the Special Servicer, the applicable Mortgage Loan Seller, the Trustee, the Certificate Administrator, the
Operating Advisor (solely in its capacity as Operating Advisor) and, if no Consultation Termination Event is continuing, the Directing
Holder, and the Special 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
discovery of the Material Defect or receipt of such notice or (ii) in the case of a Material Defect relating to a Mortgage
Loan not being a Qualified Mortgage, the earlier of (x) the discovery by the Mortgage Loan Seller or any party to this Agreement
of such Material Defect or (y) receipt of notice of a discovery of such Material Defect from any party to this Agreement
by the Mortgage Loan Seller, (such ninety (90) day period, the “Initial Cure Period”), (A) cure such Material
Defect in all material respects, at such Mortgage Loan Seller’s own expense, including reimbursement of any related reasonable
additional expenses of the Trust reasonably incurred by any party to this Agreement, (B) repurchase the affected Mortgage
Loan or REO Mortgage Loan (or, in the case of a Joint Mortgage Loan, the applicable Mortgage Loan Seller Percentage Interest thereof)
(excluding any related Companion Loan, if applicable) at the applicable Purchase Price and in conformity with the applicable Mortgage
Loan Purchase Agreement and this Agreement or (C) substitute a Qualified Substitute Mortgage Loan (other than with respect
to any Mortgage Loan that is part of a Whole Loan, for which no substitution will be permitted) for such affected Mortgage Loan
or REO Mortgage Loan, and pay any Substitution Shortfall Amount in connection with such substitution (provided that in
no event shall any such substitution occur on or after the second anniversary of the Closing Date) and pay the Master Servicer
for deposit into the Collection Account, any Substitution Shortfall Amount in connection therewith and in conformity with the
applicable Mortgage Loan Purchase Agreement and this Agreement; provided, however, that except with respect to a
Material Defect resulting solely from the failure by the Mortgage Loan Seller to deliver to the Trustee or Custodian the actual
policy of lender’s title insurance required pursuant to clause (viii) of the definition of Mortgage File by a date
not later than eighteen (18) months following the Closing Date, if such Material Defect is capable of being cured but is not cured
within the Initial Cure Period, and the applicable Mortgage Loan Seller has commenced and is diligently proceeding with the cure
of such Material Defect within the Initial Cure Period, the applicable Mortgage Loan Seller will 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 Mortgage
Loan (or, in the case of a Joint Mortgage Loan, the applicable Mortgage Loan Seller Percentage Interest thereof) or substitute
a Qualified Substitute Mortgage Loan (other than with respect to any Mortgage Loan that is part of a Whole Loan, for which no
substitution will be permitted) and pay any Substitution Shortfall


 






    -140-


     


    

 


Amount in connection with such substitution) and provided,
further, that with respect to such Extended Cure Period the applicable Mortgage Loan Seller must 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 (other than with respect
to an Excluded Loan and only while no Consultation Termination Event is continuing) the Directing Holder, setting forth the reason
such Material Defect is not capable of being cured within the Initial Cure Period and what actions the applicable Mortgage Loan
Seller is pursuing in connection with the cure thereof and stating that the applicable Mortgage Loan Seller anticipates that such
Material Defect will be cured within the Extended Cure Period; and provided, further, that, if any such Material
Defect is still not cured after the Initial Cure Period and any such Extended Cure Period solely due to the failure of the Mortgage
Loan Seller to have received the recorded document, then the Mortgage Loan Seller shall be entitled to continue to defer its cure,
substitution or repurchase obligations in respect of such Material Defect so long as the Mortgage Loan Seller certifies to the
Trustee, the Special Servicer, the Master Servicer and the Certificate Administrator every thirty (30) days thereafter that the
Material Defect is still in effect solely because of its failure to have received the recorded document and that the Mortgage
Loan Seller is diligently pursuing the cure of such defect (specifying the actions being taken), except that no such deferral
of cure, substitution or repurchase may continue beyond the date that is 18 months following the Closing Date. Any such repurchase
or substitution of a Mortgage Loan shall be on a whole loan, servicing released basis. Notwithstanding the foregoing, any Material
Defect which causes any Mortgage Loan not to be a Qualified Mortgage shall be deemed to materially and adversely affect the interests
of Certificateholders therein, and (subject to the applicable Mortgage Loan Seller’s right to cure such Material Defect
during the Initial Cure Period) such Mortgage Loan 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 (or, in the case of a Joint Mortgage Loan, the applicable Mortgage Loan Seller Percentage Interest thereof) remitted
by the applicable Mortgage Loan Seller are to be remitted by wire transfer to the Master Servicer for deposit into the Collection
Account.


 


If
a Mortgage Loan Seller, in connection with a Material Defect (or an allegation of a Material Defect) pertaining to a Mortgage
Loan, 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, while no Control Termination Event is continuing and other than in respect of any Mortgage
Loan that is not a Servicing Shift Mortgage Loan or an Excluded Loan with respect to such party, with the consent of the Directing
Holder) (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).
The Loss of Value Payment includes the portion of any Liquidation Fees payable to the Special Servicer in respect of such Loss
of Value Payment and the portion of fees and reimbursable expenses of the Asset Representations Reviewer attributable to the Asset
Review of such Mortgage Loan 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


 






    -141-


     


    

 


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 precludes the
Mortgage Loan Seller or the Special Servicer 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.


 


Contemporaneously
with its execution of each Mortgage Loan Purchase Agreement, the Depositor shall cause each Mortgage Loan Seller to deliver powers
of attorney (one (1) PDF copy and the number of originals specified in the related Mortgage Loan Purchase Agreement) substantially
in the form of the applicable exhibit to the related Mortgage Loan Purchase Agreement to the Master Servicer and the Special Servicer,
that permits such parties to take such other action as is necessary to effect the delivery, assignment and/or recordation of any
documents and/or instruments relating to any Mortgage Loan which have not been delivered, assigned or recorded at the time required
for enforcement by the Trust. Pursuant to each Mortgage Loan Purchase Agreement, each Mortgage Loan Seller will be required to
effect (at the expense of such Mortgage Loan Seller) the assignment and recordation of its respective Mortgage Loan documents
until the assignment and recordation of all such Mortgage Loan documents has been completed.


 


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


 


If
any Breach pertains to a representation or warranty that the related Mortgage Loan documents or any particular Mortgage Loan document
requires the related Mortgagor to bear the costs and expenses associated with any particular action or matter under such Mortgage
Loan document(s), then the related Mortgage Loan Seller may cure such Breach within the applicable cure period (as the same may
be extended) by reimbursing the Trust (by wire transfer of immediately available funds) for (i) the reasonable amount of
any such costs and expenses incurred by the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee
or the Trust that are incurred as a result of such Breach and have not been reimbursed by the related Mortgagor and (ii) if
such Mortgage Loan is or was a Delinquent Loan subject to an Asset Review, the amount of any fees payable, without duplication,
pursuant to Section 12.02(b) to the extent not previously paid by the Mortgage Loan Seller to the Asset Representations
Reviewer attributable to the Asset Review of such Mortgage Loan; provided, however, that if the Breach relates to
a Joint Mortgage Loan, each applicable Mortgage Loan Seller shall be responsible for its Mortgage Loan Seller Percentage Interest
of all such costs and expenses unless such Breach relates solely to the Mortgage Note contributed by such Mortgage Loan Seller;
provided, further, however, that if any such costs and expenses exceed $10,000, the related Mortgage Loan
Seller may either repurchase or substitute for the related Mortgage Loan as provided above or pay such costs and expenses. Except


 



    -142-


     


    




as provided in the proviso to the immediately preceding sentence, if the related Mortgage Loan Seller (or, in the case of a Mortgage
Loan sold by a Guaranteed Seller, if such Guaranteed Seller or the related Guarantor) remits the amount of such costs and expenses,
such Mortgage Loan Seller shall be deemed to have cured such Breach in all respects upon its making such remittance. 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 by the Special Servicer to the Master Servicer,
who shall then remit such funds) to the applicable Mortgage Loan Seller effecting the related repurchase or substitution promptly
following receipt. Notwithstanding anything contained in this Agreement or the related Mortgage Loan Purchase Agreement, no delay
in either the discovery of a Material Defect or in providing notice of such Material Defect shall relieve the applicable Mortgage
Loan Seller of its obligation to cure, repurchase or substitute for (or make a Loss of Value Payment with respect to) the related
Mortgage Loan if it is otherwise required to do so under the related Mortgage Loan Purchase Agreement and/or this Article II
unless (i) the related Mortgage Loan Seller did not otherwise discover or have knowledge of such Material Defect, (ii) such
delay is a result of the failure by a party to the applicable Mortgage Loan Purchase Agreement, or this Agreement (other than
the Asset Representations Reviewer), to provide prompt notice as required by the terms of the applicable Mortgage Loan Purchase
Agreement, or this Agreement, after such party has actual knowledge of such Material Defect (knowledge shall not be deemed to
exist by reason of the Custodial Exception Report), (iii) such Material Defect does not relate to the applicable Mortgage
Loan not being a Qualified Mortgage and (iv) such delay precludes such Mortgage Loan Seller from curing such Material Defect.


 


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


 






    -143-


     


    

 


(c)            
Subject to the applicable Mortgage Loan Seller’s right to cure as contemplated above in this Section 2.03, and
further subject to Section 2.01(b) and Section 2.01(c), any of the following shall cause a document in
the Mortgage File to be deemed to have a “Defect” that constitutes a Material Defect and to be conclusively presumed
to materially and adversely affect the interests of Certificateholders in a Mortgage Loan (but solely with respect to clause (a))
and to be deemed to materially and adversely affect the interest of the Certificateholders in and the value of a Mortgage Loan:
(a) the absence from the Mortgage File of the original signed Mortgage Note, unless the Mortgage File contains a signed lost
note affidavit and indemnity with a copy of the Mortgage Note that appears to be regular on its face; (b) the absence from
the Mortgage File of the original signed Mortgage that appears to be regular on its face, unless there is included in the Mortgage
File either a copy of the Mortgage with evidence of recording thereon or a copy of the Mortgage and a certificate from the related
Mortgage Loan Seller stating that the original signed Mortgage was sent for recordation (or certified by the applicable recorder’s
office); (c) the absence from the Mortgage File of the item called for by clause (viii) of the definition of
Mortgage File; (d) the absence from the Mortgage File of any intervening assignments required to create a complete chain
of assignments to the Trustee on behalf of the Trust, unless there is included in the Mortgage File either a copy of the assignment
with evidence of recording thereon or a copy of the intervening assignment and a certificate from the related Mortgage Loan Seller
stating that the original intervening assignments were sent for filing or recordation (or certified by the applicable recorder’s
office), as applicable; (e) the absence from the Mortgage File of any required letter of credit (except as permitted under
Section 2.01(b)); or (f) with respect to any related leasehold Mortgage Loan, the absence from the related Mortgage
File of a copy (or an original, if available) of the related Ground Lease; provided, however, that no Defect (except
the Defects previously described in subclauses (a) through (f) of this Section 2.03(c)) shall be
considered to materially and adversely affect the value of the related Mortgage Loan, the value of the related Mortgaged Property
or the interests of the Trustee or Certificateholders unless the document with respect to which the Defect exists is required
in connection with an imminent enforcement of the mortgagee’s rights or remedies under the related Mortgage Loan, defending
any claim asserted by any Mortgagor or third party with respect to the related Mortgage Loan, 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 subclauses (b) through
(f) of this Section 2.03(c) shall be considered to materially and adversely affect the value of such Mortgage
Loan, the value of the related Mortgaged Property or the interests of the Trustee or Certificateholders unless the related Mortgage
Loan Seller, after receipt of notice of such Defect, is unable to produce a copy of the document with respect to which the Defect
exists within a reasonable period after receiving such notice or otherwise establish that the original or copy, as applicable,
of such document has been delivered, in compliance with the terms of the related Non-Serviced PSA, to the custodian under the
related Non-Serviced PSA. Notwithstanding the foregoing, the delivery of executed escrow instructions or a binding commitment
to issue a lender’s title Insurance Policy, as provided in clause (viii) of the definition of Mortgage File
herein, in lieu of the delivery of the actual policy of lender’s title insurance, shall not be considered a Material Defect
with respect to any Mortgage File if such actual policy is delivered to the Custodian not later than eighteen (18) months following
the Closing Date. Notwithstanding the foregoing, to the extent a Mortgage Loan Seller has otherwise complied with its document
delivery requirements under this Agreement and the related Mortgage Loan Purchase Agreement, if the Custodian has


 






    -144-


     


    

 


acknowledged
receipt pursuant to Section 2.02 above of a document that is part of the Mortgage File or a Mortgage Loan Seller can
otherwise prove delivery of the document, and the Custodian subsequently loses a document, the fact that such document is lost
may not be utilized as the basis for a claim of a Material Defect against a Mortgage Loan Seller pursuant to Section 6(e)
of the related Mortgage Loan Purchase Agreement and/or this Section 2.03 and the Custodian shall be liable for any
such loss to the extent provided for in Section 8.01.


 


(d)           
In connection with any repurchase of, or substitution of a Qualified Substitute Mortgage Loan for, a Mortgage Loan 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 in the same manner as provided in Section 6 of the related Mortgage Loan Purchase Agreement and, if
applicable, the definition of “Mortgage File” herein, so as to vest in such Mortgage Loan Seller 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 6 of each of the Mortgage Loan Purchase Agreements provides the sole remedy available to the Certificateholders (subject
to the limitations on the rights of the Certificateholders under this Agreement), or the Trustee on behalf of the Certificateholders,
the Master Servicer or the Special Servicer, with respect to any Defect in a Mortgage File or any Breach of any representation
or warranty with respect to a Mortgage Loan set forth in or required to be made pursuant to Section 6 of any of the Mortgage
Loan Purchase Agreements; provided, however, that the foregoing shall in no way limit the ability of the Special
Servicer or the Trustee to take any action against a Guarantor, to the extent provided for pursuant to the related Mortgage Loan
Purchase Agreement, including, without limitation, pursuant to Section 24 thereof.


 


(f)             
The Special 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 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


 






    -145-


     


    

 


clauses first
and second are insufficient, then pursuant to Section 3.05(a)(viii) herein out of general collections on the
Mortgage Loans on deposit in the Collection Account. Any costs, expenses or attorneys’ fees related to a repurchase of a
Companion Loan shall be paid pursuant to the related Intercreditor Agreement or pursuant to the documents related to an Other
Securitization, if applicable.


 


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


 


(h)            
If (i) any Crossed Underlying Loan is required to be repurchased or substituted for in the manner described in this Section 2.03
and (ii) the applicable Material Defect does not constitute a Material Defect as to any other Crossed Underlying Loan
in the related Crossed Mortgage Loan Group (without regard to this paragraph), then the applicable Material Defect shall be deemed
to constitute a Material Defect as to any other Crossed Underlying Loan in the related Crossed Mortgage Loan Group for purposes
of this paragraph, and the related Mortgage Loan Seller shall repurchase or substitute for such other Crossed Underlying Loan(s)
in the related Crossed Mortgage Loan Group as provided in Section 2.03(b) unless such other Crossed Underlying Loans
satisfy the Crossed Underlying Loan Repurchase Criteria. If 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 Master Servicer or, with respect to a Specially Serviced Loan, the Special Servicer, on behalf of
the Trustee, as assignee of the Depositor, will, as set forth in the related Mortgage Loan Purchase Agreement, forbear from enforcing
any remedies against the other’s Primary Collateral but each will be permitted to exercise remedies against the Primary
Collateral securing its respective related Mortgage Loans, including with respect to the Trustee, the Primary Collateral securing
the Mortgage Loans still held by the Trustee, so long as such exercise does not materially impair the ability of the other party
to exercise its remedies against its Primary Collateral. If the exercise of the remedies by one party would materially impair
the ability of the other party to exercise its remedies with respect to the Primary Collateral securing the Crossed Underlying
Loans held by such party, then both parties have agreed in the related Mortgage Loan Purchase Agreement to forbear from exercising
such remedies until the Mortgage Loan documents evidencing and securing the relevant Mortgage Loan can be modified in a manner
that complies with the related Mortgage Loan Purchase Agreement to remove the threat of material impairment as a result of the
exercise of remedies.


 


(k)            
(i) If 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 related Mortgage Loan Seller and each other party to this
Agreement. Subject to Section 2.03(l), the Special Servicer (the “Enforcing Servicer”) shall be
the Enforcing Party with respect to a Certificateholder Repurchase Request.


 


(ii)              
If the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator or the Operating Advisor
(solely in its capacity as Operating Advisor) obtains knowledge of a Material Defect with respect to a Mortgage Loan, that


 






    -147-


     


    

 


party
shall deliver prompt written notice of such Material Defect to each other party to this Agreement identifying the applicable Mortgage
Loan and setting forth the basis for such allegation (an “PSA Party Repurchase Request” and, either a Certificateholder
Repurchase Request or a PSA Party Repurchase Request, the “Repurchase Request”) and the Special Servicer shall
promptly send the PSA Party Repurchase Request to the related Mortgage Loan Seller. Prior to the occurrence of a Resolution Failure,
the Special 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)              
If the Repurchase Request is not Resolved within 180 days after the Mortgage Loan Seller receives the Repurchase Request (a “Resolution
Failure”), then the provisions described in Section 2.03(l) below shall apply.  Receipt of the
Repurchase Request shall be deemed to occur two (2) Business Days after the Repurchase Request is sent to the related Mortgage
Loan Seller.


 


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


 


(l)             
(i) After a Resolution Failure occurs with respect to a Repurchase Request regarding a Mortgage Loan (whether the Repurchase Request
was initiated by an Initial Requesting Certificateholder or by a party to this Agreement), 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 thirty (30) days of the date of such notice and a disclaimer that responses received after such thirty
(30) day period shall not be taken into consideration, (b) a statement that if any Certificateholder disagrees with the Proposed
Course of Action, the Enforcing Servicer shall be compelled to follow or accept the course of action agreed to and/or proposed
by the majority of the responding Certificateholders that involves referring the matter to mediation or arbitration, as the case
may be, (c) a statement that responding Certificateholders will be required to certify their holdings in connection with such
response, (d) a statement that only responses clearly marked “agree” or “disagree” with such Proposed
Course of Action will be taken into consideration and (e) instructions for responding Certificateholders to send their responses
to the applicable Enforcing Servicer and the Certificate Administrator. If (a) the Enforcing Servicer’s intended course
of action with respect to the Repurchase Request does not involve pursuing further action to exercise rights against the applicable
Mortgage Loan Seller with respect to the Repurchase Request but the Initial Requesting Certificateholder, if any, or any other
Certificateholder or


 






    -148-


     


    

 


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


 


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


 


(iii)              
Promptly and in any event within 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)


 






    -149-


     


    

 


Business Days following the Dispute Resolution Cut-off Date. The Enforcing Servicer shall be entitled to establish
procedures the Enforcing Servicer deems in good faith to be in accordance with the Servicing Standard relating to the timing and
extent of such consultations. No later than 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 shall enforce
the rights of the Trust with respect to the Repurchase Request and no Certificateholder or Certificate Owner will have any further
right to elect to refer the matter to mediation or arbitration.


 


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


 


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


 


(vii)              
If 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.


 






    -150-


     


    

 


(viii)            
None of the Depositor, the Mortgage Loan Seller with respect to the subject Mortgage Loan or 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 if the initial method is unsuccessful.


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


(ii)            The arbitrator shall be impartial, an attorney and have at least fifteen (15) years of experience in commercial litigation and
either commercial real estate finance or commercial mortgage-backed securitization matters or other complex commercial transactions
and who will be appointed from a list of neutrals maintained by the Arbitration Services Provider. Upon being supplied a list
of at least ten potential arbitrators by the


 






    -151-


     


    

 


Arbitration Services Provider each party will have the right to exercise two peremptory
challenges within fourteen (14) days and to rank the remaining potential arbitrators in order of preference. The Arbitration Services
Provider will select the 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 parties,
with the goal of expediting the proceeding and completing the arbitration within 120 days. The arbitrator may 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 may
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.


 






    -152-


     


    

 


(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;


 


(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 has subject
matter jurisdiction, or if the Southern District of New York has no jurisdiction, then in the Supreme Court of the State of New
York for the County of New York. The arbitration proceedings may not be stayed unless so ordered by the court.


 


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


 


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


 






    -153-


     


    

 


deposited in
the Collection Account. The agreement with the arbitrator or mediator, as the case may be, shall provide that if 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)              
If a Requesting Certificateholder is the Enforcing Party, the Requesting Certificateholder is required to pay any expenses allocated
to the Enforcing Party in the arbitration proceedings or any expenses that the Enforcing Party agrees to bear in the mediation
proceedings.


 


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


 


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


 


(viii)           If the method of dispute resolution selected is unsuccessful, the Requesting Certificateholder shall not elect to then utilize
the alternative method.


 


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


 


(p)           
Notwithstanding anything to the contrary herein, with respect to any Joint Mortgage Loan, the obligations of each of the applicable
Mortgage Loan Sellers to repurchase or substitute with respect to a Material Defect with respect to the related Mortgage Loan
shall be limited to a repurchase or substitution with respect to the Mortgage Note it sold to the Depositor in accordance with
the related Mortgage Loan Purchase Agreement. With respect to any Joint Mortgage Loan, any cure by either of the applicable Mortgage
Loan Sellers with respect to the Mortgage Note sold by it to the Depositor in accordance with the related Mortgage Loan Purchase
Agreement that also cures the Material Defect with respect to the entire related Joint Mortgage Loan shall satisfy the cure obligations
of both Mortgage Loan Sellers with respect to such Joint Mortgage Loan.

(in the case of the Class R Certificates, the Class LR Interest and the Class UR Interest); (iv) the Trustee acknowledges
the creation of the Grantor Trust (as described in Section 2.05 below); and (v) the Trustee acknowledges that it has

cause the Authenticating Agent to deliver to or upon the order of the Depositor such Certificates, and the Depositor hereby acknowledges
the receipt by it, or its designees, of such Certificates in authorized denominations, evidencing beneficial ownership of their
respective portions of the Grantor Trust.

of the Master Servicer or the Special Servicer, as applicable; (iii) the obligation, if any, of the Master Servicer to make
Advances; (iv) the right of the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates to
receive compensation for its services and reimbursement for its costs hereunder or with respect to any particular transaction;
(v) the ownership, servicing or management for others of (a) the Non-Serviced Mortgage Loans and the Non-Serviced Companion
Loans or (b) any other mortgage loans, subordinate debt, mezzanine loans or properties not covered by this Agreement or held
by the Trust by the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates; (vi) any debt
that the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates, has extended to any Mortgagor
or an Affiliate of any Mortgagor (including, without limitation, any mezzanine financing); (vii) any option to purchase any
Mortgage Loan or the related Companion Loan the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates,
may have; and (viii) any obligation of the Master Servicer or the Special Servicer, or any of their respective Affiliates,
to repurchase, substitute for or make a Loss of Value Payment with respect to a Mortgage Loan as a Mortgage Loan Seller (if the
Master Servicer or the


 






    -156-


     


    

 


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 service and administer (i) any Mortgage
Loans (other than the Non-Serviced Mortgage Loans, except in the case of Section 2.03(f) and Section 2.03(k)
through Section 2.03(o)), any related Serviced Companion Loans as to which a Servicing Transfer Event 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 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 is not 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, is not responsible 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, is not responsible 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 (i) the processing of any Major Decision or Special Servicer Decision by the Special
Servicer in accordance with the terms of this Agreement and (ii) Section 3.19, the Master Servicer shall be obligated
to service and administer any Non-Specially Serviced Loan or any related Serviced Companion Loan. The Special Servicer shall make
the property inspections, use its reasonable efforts to collect the financial statements, budgets, operating statements and rent
rolls and forward to the Master Servicer the reports in respect of the related Mortgaged Properties with respect to Specially
Serviced Loans in accordance with Section 3.12. After notification to the Master Servicer, the Special Servicer may
contact the Mortgagor of any Non-Specially Serviced Loan if efforts by the Master Servicer to collect required financial information
have been unsuccessful or any other issues remain unresolved. Such contact shall be coordinated through and with the cooperation
of the Master Servicer. No provision herein contained shall be construed as an express or implied guarantee by the Master Servicer
or the Special Servicer of the collectability or recoverability of payments on the Mortgage Loans or any related Serviced Companion
Loan or shall be construed to impair or adversely affect any rights or benefits provided by this Agreement to the Master Servicer
or the Special Servicer (including with respect to Servicing Fees, Special Servicing Fees or the right to be reimbursed for Advances
and interest accrued thereon). Any provision in this Agreement for any Advance by the Master Servicer or the Trustee is intended
solely to provide liquidity for the benefit of the


 






    -157-


     


    

 


Certificateholders and not as credit support or otherwise to impose on any
such Person the risk of loss with respect to one or more of the Mortgage Loans or any related Serviced Companion Loans. No provision
hereof shall be construed to impose liability on the Master Servicer or the Special Servicer for the reason that any recovery
to the Certificateholders in respect of a Mortgage Loan at any time after a determination of present value recovery is less than
the amount reflected in such determination.


 


(b)           
Subject only to the Servicing Standard and the terms of this Agreement (including, without limitation, Section 6.08)
and of the respective Mortgage Loans or any related Serviced Companion Loans and any related Intercreditor Agreement, if applicable,
and applicable law, the Master Servicer and the Special Servicer each has full power and authority, acting alone or, in the case
of the Master Servicer, subject to Section 3.20, through one or more Sub-Servicers, to do or cause to be done any
and all things in connection with such servicing and administration for which it is responsible which it may deem necessary or
desirable. Without limiting the generality of the foregoing, each of the Master Servicer and the Special Servicer, in its own
name (or in the name of the Trustee and, if applicable, the related Serviced Companion Noteholder), is hereby authorized and empowered
by the Trustee to execute and deliver, on behalf of the Certificateholders (and, with respect to a Serviced Companion Loan, the
related Serviced Companion Noteholder) and the Trustee or any of them, with respect to each Mortgage Loan 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 upon request, furnish, or cause to be furnished, to the Master Servicer or the Special Servicer any powers of
attorney in the form of Exhibit R-1 or Exhibit R-2, respectively (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 is not 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


 






    -158-


     


    

 


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 is not required to obtain the Trustee’s consent or indicate the Master Servicer’s or the Special Servicer’s,
as applicable, representative capacity)) or (ii) take any action with the intent to cause, and that actually causes, the
Trustee to be required to be registered to do business in any state.


 


(c)            
To the extent the Master Servicer is permitted pursuant to the terms of the related Mortgage Loan documents or Companion Loan
documents (including any related Intercreditor Agreement) to exercise its discretion with respect to any action that requires
Rating Agency Confirmation from each Rating Agency or Companion Loan Rating Agency Confirmations, 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 Companion Loan Rating Agency Confirmation, 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 Companion Loan Rating Agency Confirmation, the Master Servicer shall use reasonable efforts to have the
Mortgagor bear such costs and expenses. The Master Servicer is not responsible for the payment of such costs and expenses out
of pocket other than as a Servicing Advance.


 


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


 


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


 


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


 






    -159-


     


    

 


and that the Master Servicer or the Special Servicer shall service the related Mortgage Loan for the benefit of the Certificateholders.
If a letter of credit is required to be drawn upon earlier than the date the applicable Mortgage Loan Seller has notified the
provider of such letter of credit pursuant to clause (x) of the immediately preceding sentence, such Mortgage Loan
Seller shall 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 will have any liability
for the failure of any Mortgage Loan Seller to perform its obligations under the related Mortgage Loan Purchase Agreement.


 


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


 


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


 


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






 






    -160-


     


    

 


Companion
Loan, in accordance with the respective outstanding principal balances of the related Mortgage Loan and Serviced Pari Passu Companion
Loan.


 


(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 will be payable out of the Trust Fund and the Master Servicer will have no obligation to make any Advance on or after the
date such Serviced Mortgage Loan ceases to be part of the Trust Fund; provided, however, that if, in the case of
any Serviced Whole Loan, the related Serviced Companion Loan continues to be included in an Other Securitization, then for so
long as a separate servicing agreement (pursuant to the related Intercreditor Agreement) has not been entered into, the Master
Servicer shall inform the related Other Servicer of any need to make Servicing Advances with respect to a Serviced Whole Loan
within three (3) Business Days of determining that such an Advance is necessary or being notified that such an Advance is necessary,
or in the case of a Servicing Advance that needs to be made on an emergency or urgent basis, within one (1) Business Day. With
respect to Servicing Advances made by any Other Servicer as contemplated in the second proviso to the preceding sentence, the
Master Servicer shall, from collections on the related Serviced Whole Loan (but never out of general collections on the Mortgage
Loans and REO Properties) received by the Master Servicer, reimburse the Other Servicer for such Servicing Advances in the same
manner and on the same level of priority as if such Servicing Advances had been made by the Master Servicer hereunder.


 


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


 






    -161-


     


    

 


Non-Serviced Master Servicer and Non-Serviced
Special Servicer in accordance with the related Non-Serviced PSA, and (ii) if (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 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.


 


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


 


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


 






    -162-


     


    

 


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

Loan and unpaid interest at the Reimbursement Rate on such Advances and, if applicable, unreimbursed and unpaid additional expenses

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)(x) 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 (y) with
respect to any accrued and unpaid interest that was not advanced due to a determination that the related P&I Advance would
be a Nonrecoverable Advance, the amount of interest that (absent such determination of nonrecoverability preventing such P&I
Advance from being made) would not have been advanced because of the reductions in the amount of related P&I Advances for
such Mortgage Loan that would have occurred in connection with the 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;

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


 


sixth,

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


 






    -164-


     


    

 


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; and provided, further, that with respect to each Serviced Mortgage Loan, amounts
collected with respect to the related Serviced Whole Loan shall be allocated first pursuant to the terms of the related Intercreditor

each Serviced Whole Loan, exclusive of any amounts payable to the holder(s) of the related Companion Loan(s), as applicable, pursuant
to the terms of the related Intercreditor Agreement) shall be applied in the following order of priority:


 


first,

Loan and interest at the Reimbursement Rate on all Advances and, if applicable, unreimbursed and unpaid additional Trust Fund

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 (y) with respect to any accrued and unpaid interest that was not advanced due to a
determination that the related P&I Advance would be a Nonrecoverable Advance, the amount of interest that (absent such determination
of nonrecoverability preventing such P&I Advance from being made) would not have been advanced because of the reductions in
the amount of related P&I Advances for such Mortgage Loan that would have occurred in connection with the related Appraisal
Reduction Amounts or (B) accrued at the related Net Mortgage Rate on the portion of the Stated Principal Balance of such Mortgage
Loan equal to any related Collateral Deficiency Amount in effect from time to time and as to which no P&I Advance was made;


 


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


 


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


 






    -165-


     


    

 


P&I Advances for such Mortgage Loan that have occurred in connection with related
Appraisal Reduction Amounts or would have occurred in connection with related Appraisal Reduction Amounts but for such P&I
Advance not having been made as a result of a determination by the Master Servicer that such P&I Advance would have been a
Nonrecoverable Advance, plus (B) any unpaid interest (exclusive of Default Interest and Excess Interest) that accrued at the related
Net Mortgage Rate on the portion of the Stated Principal Balance of such Mortgage Loan equal to any related Collateral Deficiency
Amount in effect from time to time and as to which no P&I Advance was made (to the extent collections have not been allocated
as recovery of accrued and unpaid interest pursuant to this clause fifth or clause fifth of Section 3.02(b)
on earlier dates);


 


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


 


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


 


eighth,
as a recovery of any assumption fees, assumption application 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, if applicable, accrued and unpaid Excess
Interest (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; and provided, further,
that with respect to each Serviced Mortgage Loan, amounts collected with respect to the related Serviced Whole Loan shall be allocated
first pursuant to the terms of the related Intercreditor Agreement and then, any amounts allocated to the related Serviced Mortgage
Loan shall be subject to application as described above.


 


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


 


(c)            
To the extent consistent with the terms of the Mortgage Loans (and, with respect to each Serviced Whole Loan, the related Serviced
Companion Loan and the related Intercreditor Agreement) and applicable law, the Master Servicer shall apply all Insurance and
Condemnation Proceeds it receives on a day other than the Due Date to amounts due and owing


 






    -166-


     


    

 


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


 


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


 


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


 


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

on deposit
in Servicing Accounts may only be invested in accordance with the terms of the related Mortgage Loan documents and Companion Loan
documents, as applicable, or in Permitted Investments in accordance with the provisions of Section 3.06. Servicing
Accounts shall be Eligible Accounts to the extent permitted by the terms of the related Mortgage Loan documents. Withdrawals of
amounts so deposited from a Servicing Account may be made only to: (i) effect payment of items for which Escrow Payments
were collected and comparable items; (ii) reimburse the Trustee and then the Master Servicer, if applicable, for any Servicing
Advances; (iii) refund to Mortgagors any sums as may be determined to be overages; (iv) pay interest to Mortgagors on
balances in the Servicing Account, if required by applicable law or the terms of the related Mortgage Loan or Companion Loan and
as described below or, if not so required, to the Master Servicer; (v) after the occurrence of an event of default under
the related Mortgage Loan or Companion Loan, apply amounts to the indebtedness under the applicable Mortgage Loan or Companion
Loan; (vi) withdraw amounts deposited in error; (vii) pay Penalty Charges to the extent permitted by the related Mortgage
Loan documents; or (viii) clear and terminate the Servicing Account at the termination of this Agreement in accordance with
Section 9.01. As part of its servicing duties, the Master Servicer shall pay or cause to be paid to the Mortgagors
interest on funds in Servicing Accounts, to the extent required by law or the terms of the related Mortgage Loan or Companion
Loan; provided, however, that in no event shall the Master Servicer be required to remit to any Mortgagor any amounts
in excess of actual net investment income or funds in the related Servicing Account. If allowed by the related Mortgage Loan documents
and applicable law, the Master Servicer may charge the related Mortgagor an administrative fee for maintenance of the Servicing
Accounts.


 


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


 






    -168-


     


    

 


Loans or Companion Loan that it is responsible for servicing
hereunder, shall use efforts consistent with the Servicing Standard to cause the Mortgagor to comply with its obligation to make
payments in respect of such items at the time they first become due and, in any event, prior to the institution of foreclosure
or similar proceedings with respect to the related Mortgaged Property for nonpayment of such items.


 


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


 






    -169-


     


    

 


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, the Master Servicer is not required to reimburse the
Special Servicer for any such Servicing Advance if the Master Servicer determines in accordance with the Servicing Standard that
such Servicing Advance, although not characterized by the Special Servicer as a Nonrecoverable Servicing Advance, is in fact a
Nonrecoverable Servicing Advance. The Master Servicer shall notify the Special Servicer in writing of such determination and,
if applicable, such Nonrecoverable Servicing Advance shall be reimbursed to the Special Servicer pursuant to Section 3.05
out of general collections.


 


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 may
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 and such non-recoverability determination
may be conclusively relied upon by, and shall be binding upon, the Master Servicer. Notwithstanding anything to the contrary in
this Agreement, in the absence of any determination by the Special Servicer that a 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 permitted to make its own determination that any such Servicing 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 may make its own subsequent determination that any remaining portion of any such previously made
or proposed Servicing Advance is a Nonrecoverable Advance. All such Advances shall be reimbursable in the first instance from
related collections from the Mortgagors and further as provided in Section 3.05(a). No costs incurred by the Master
Servicer or the Special Servicer in effecting the payment of real estate taxes, assessments and, if applicable, ground rents on
or in respect of the Mortgaged Properties shall, for purposes hereof, including, without limitation, the Certificate Administrator’s
calculation of monthly distributions to Certificateholders, be added to the unpaid principal balances of the related Mortgage
Loans or any related Serviced Companion Loan, if applicable, notwithstanding that the terms of such Mortgage Loans or related
Serviced Companion Loan, if applicable, so permit. If the Master Servicer fails to make any required Servicing Advance as and
when due (including any applicable cure periods), to the extent the Trustee has actual knowledge of such failure, the Trustee
shall make such Servicing Advance pursuant to Section 7.05. Notwithstanding anything herein to the contrary, no Servicing
Advance shall be required hereunder if such Servicing Advance would, if made, constitute a Nonrecoverable Servicing Advance. In
addition, the Master Servicer shall consider Unliquidated Advances in respect of prior Servicing Advances for purposes of nonrecoverability
determinations. The Special Servicer has no obligation to make any Servicing Advances under this Agreement.


 






    -170-


     


    

 


Notwithstanding
the foregoing provisions of this Section 3.03(c), the Master Servicer is not required to reimburse the Special Servicer
out of its own funds for, or to make at the direction of the Special Servicer, any Servicing Advance if the Master Servicer determines
that such Servicing Advance, although not characterized by the Special Servicer as a Nonrecoverable Servicing Advance, is a Nonrecoverable
Servicing Advance. The Master Servicer shall notify the Special Servicer in writing of such determination and, if applicable,
such Nonrecoverable Servicing Advance shall be reimbursed to the Special Servicer pursuant to Section 3.05(a).


 


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


 


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


 






    -171-


     


    

 


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


 


(e)            
To the extent an operations and maintenance plan is required to be established and executed pursuant to the terms of a Mortgage
Loan (other than a Non-Serviced Mortgage Loan), 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.


 


Section 3.04      
The Collection Account, the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Companion
Distribution Account, the Interest Reserve Account, the Loan REMIC Residual Interest Account, the Excess Interest Distribution
Account and the Gain-on-Sale Reserve Account. (a)  The Master Servicer shall establish and maintain, or cause to
be established and maintained, a Collection Account in which the Master Servicer shall deposit or cause to be deposited, in no
event later than the second Business Day following receipt of properly identified funds (in the case of payments by Mortgagors
or other collections on the Mortgage Loans or Companion Loans), except as otherwise specifically provided herein, the following
payments and collections received or made by or on behalf of it subsequent to the Cut-off Date (other than in respect of principal
and interest on the Mortgage Loans or Companion Loans due and payable on or before the Cut-off Date (including the Miami Design
District Deferred 2020 Collection Amount), which payments shall be delivered promptly to the appropriate Mortgage Loan Seller
or its respective designee and other than any amounts received from Mortgagors which are received in connection with the purchase
of defeasance collateral), or payments (other than Principal Prepayments) received by it on or prior to the Cut-off Date but allocable
to a period subsequent thereto:


 


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


 


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


 






    -172-


     


    

 


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


 


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


 


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


 


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


 


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


 


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


 


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


 






    -173-


     


    

 


Upon
receipt of any of the foregoing amounts in clauses (i) through (iv) above with respect to any Specially Serviced
Loans, the Special Servicer shall remit within one (1) Business Day such amounts to the Master Servicer for deposit into the Collection
Account, in accordance with this Section 3.04(a); provided that to the extent any of the foregoing amounts are received
after 2:00 p.m. (Eastern time) on any given Business Day, the Special Servicer shall use commercially reasonable efforts to remit
such amounts within one (1) Business Day of receipt of such amount, but, in any event, the Special Servicer shall remit such amounts
to the Master Servicer within two (2) Business Days of receipt of such amounts. 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 Section 3.06. As of the Closing Date, the
Collection Account for the Master Servicer shall be located at the offices of Midland Loan Services, a Division of PNC Bank, National
Association. The Master Servicer shall give notice to the Trustee, the Special Servicer, the Certificate Administrator and the
Depositor of the new location of the Collection Account prior to any change thereof.


 


(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
the Holders of the Class Z Certificates) and the Trustee as Holder of the Lower-Tier Regular Interests, (ii) the Upper-Tier
REMIC Distribution Account in trust for the benefit of the Certificateholders (other than the Holders of the Class Z Certificates)
and the Trustee as Holder of the Lower-Tier Regular Interests and (iii) the Excess Interest Distribution Account for the
benefit of the Holders of the Class Z 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 after giving effect to withdrawals of funds pursuant to Section 3.05(a)(ii). For the avoidance of doubt, so
long as Wells Fargo Bank, National Association is the Certificate Administrator, all funds held in the Distribution Accounts,
the Interest Reserve Account and the Excess Interest Distribution Account shall remain uninvested.


 


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,
to be held for the benefit of the related Companion Holder and shall, within two (2) Business Days following the Companion Paying
Agent’s receipt of properly identified and available funds, deposit in the Companion Distribution Account any and all amounts
received by the Companion Paying Agent that are required by the terms of this Agreement or the applicable Intercreditor Agreement
to be deposited therein; provided, however, that the Companion Paying Agent shall separately track for each Serviced
Companion Loan all amounts deposited with respect

the Master Servicer shall, as and when required hereunder, deliver to the Certificate Administrator for deposit in the Lower-Tier
REMIC Distribution Account:

(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

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 Distribution

    -176-


     


    

 


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 Wells Fargo Bank, National Association, as Trustee for the Holders of the CSAIL
2021-C20 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2021-C20 as their interests may appear”,

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
2022, 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 e-mail to cts.cmbs.bond.admin@wellsfargo.com, along with a copy of
the invoice, and a subject line reference of “CSAIL 2021-C20 - Legal Fee Reserve Account”. The Legal Fee Reserve Account
will not be a part of the Trust Fund, any Trust REMIC or the Grantor Trust. 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 will have no responsibility in connection therewith.


 


The
Certificate Administrator has 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.

For

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

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 Class Z 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 prior to the Determination Date for the applicable Collection Period.


 


(d)

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 and maintain the Loan REMIC Residual Distribution Account in the name of the Certificate
Administrator, in trust for the benefit of the Class R Certificateholders and the Trustee as the Holder of the Loan REMIC
Residual Interests. The Loan REMIC Residual 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 withdraw from the

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, as applicable, in connection
with such sale and, with respect to the Mortgage Loans, remit such funds to the Master Servicer who shall then remit such funds
to the Certificate Administrator for deposit into the Gain-on-Sale Reserve Account. Any gain on such disposition that is allocable
to any other 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.


 


(h)

contemplated by Section 3.05(g), the Special Servicer shall establish and maintain one or more 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, upon receipt, deposit in the Loss of Value Reserve Fund all Loss of Value
Payments received by it. The Certificate Administrator shall, based upon information obtained from the CREFC® reports
delivered by the Master Servicer pursuant to the terms hereof, account for the Loss of Value Reserve Fund as an outside reserve
fund within 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 contributed 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

be taxable on all income earned thereon.

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


 






    -190-


     


    

 


be held to maturity, unless payable on demand. Any funds held in an Investment Account shall
be held in the name of the Master Servicer or the Special Servicer, as applicable, on behalf of the Trustee (in its capacity as
such) for the benefit of the Certificateholders. The Master Servicer (in the case of the Collection Account, the Companion Distribution
Account or any Servicing Account maintained by or for the Master Servicer) and the Special Servicer (in the case of the REO Account,
Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) on behalf of the Trustee, shall
maintain continuous physical possession of any Permitted Investment of amounts in the Collection Account, the Companion Distribution
Account, the Servicing Accounts, the Loss of Value Reserve Fund or the REO Account, as applicable, that is either (i) a “certificated
security,” as such term is defined in the UCC (such that the Trustee has 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 applicable, shall take or
cause to be taken such action as the Trustee deems reasonably necessary to cause the Trustee to have control over such security
entitlement. If amounts on deposit in an Investment Account are at any time invested in a Permitted Investment payable on demand,
the Master Servicer (in the case of the Collection Account, the Companion Distribution Account or any Servicing Account maintained
by or for the Master Servicer) or the Special Servicer (in the case of the REO Account, 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, 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).
If any loss shall be incurred in respect of any Permitted Investment (as to which the Master Servicer or the Special Servicer,
as applicable, would have been entitled to any Net


 






    -191-


     


    

 


Investment Earnings hereunder) directed to be made by the Master Servicer or
the Special Servicer, as applicable, and on deposit in any of the Collection Account, the Companion Distribution Account, the
Servicing Account, Loss of Value Reserve Fund or the REO Account, the Master Servicer (in the case of the Collection Account,
the Companion Distribution Account or any Servicing Account maintained by or for the Master Servicer), the Special Servicer (in
the case of the REO Account, Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) shall
deposit therein, no later than the P&I Advance Date, without right of reimbursement, the amount of Net Investment Loss, if
any, with respect to such account for the period from and including the prior Distribution Date to and including the P&I Advance
Date related to the current Distribution Date; provided that neither the Master Servicer nor the Special Servicer shall
be required to deposit any loss on an investment of funds in an Investment Account if such loss is incurred solely as a result
of the insolvency of the federal or state chartered depository institution or trust company that holds such Investment Account,
so long as such depository institution or trust company satisfied the qualifications set forth in the definition of Eligible Account
at the time such investment was made (and, with respect to the Master Servicer or the Special Servicer, such federal or state
chartered depository institution or trust company is not an Affiliate of the Master Servicer or the Special Servicer, as applicable,
unless such depository institution or trust company satisfied the qualification set forth in the definition of Eligible Account
both (x) at the time the investment was made and (y) thirty (30) days prior to such insolvency).


 


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


 


Section 3.07      
Maintenance of Insurance Policies; Errors and Omissions and Fidelity Coverage. (a)  To the extent permitted by
the related Mortgage Loan documents and required by the Servicing Standard, the Master Servicer (with respect to the Mortgage
Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan) shall use efforts consistent with the
Servicing Standard to cause the Mortgagor to maintain, and the Special Servicer (with respect to REO Properties other than any
Non-Serviced Mortgaged Properties) shall maintain all insurance coverage as is required under the related Mortgage Loan documents
except to the extent that the failure of the related Mortgagor to do so is an Acceptable Insurance Default (and except as provided
in the next sentence with respect to the Master Servicer or the Special Servicer, as applicable). If the Mortgagor does not so
maintain such insurance coverage, subject to its recoverability determination with respect to any required Servicing Advance,
the Master Servicer (with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion
Loan) or the Special Servicer (with respect to REO Properties other than a Non-Serviced Mortgaged Property) shall maintain all
insurance coverage as is required under, and such insurance coverage is to be obtained from an insurer meeting the requirements
under, the related Mortgage Loan documents, but only if the Trustee has an insurable interest therein and such insurance is available
to the Master Servicer or the Special Servicer and, if available, can be obtained at commercially reasonable rates, as determined
in accordance with the Servicing Standard. Any determination that such insurance coverage is not available or not available at
commercially reasonable rates shall be made with the consent of the Directing Holder (if no

Control Termination Event is continuing
and other than with respect to any Excluded Loan as to such party) and after consultation with the Risk Retention Consultation
Party pursuant to Section 6.08(a) (other than with respect to any Excluded Loan as to such party). Such determination
shall be made by the Master Servicer (with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related
Serviced Companion Loan) or the Special Servicer (with respect to REO Properties other than any Non-Serviced Mortgaged Property)
except to the extent that the failure of the related Mortgagor to do so is an Acceptable Insurance Default as determined by the
Special Servicer; provided, however, that if any Mortgage or any other Mortgage Loan document permits the holder
thereof to dictate to the Mortgagor the insurance coverage to be maintained on such Mortgaged Property, the Master Servicer or,
with respect to an REO Property, the Special Servicer, as applicable, shall impose or maintain, as applicable, such insurance
requirements as are consistent with the Servicing Standard taking into account the insurance in place at the origination of the
Mortgage Loan; provided, further, that, with respect to the immediately preceding proviso, the Master Servicer shall
be obligated to use efforts consistent with the Servicing Standard to cause the Mortgagor to maintain (or to itself maintain)
insurance against property damage resulting from terrorist or similar acts unless the Mortgagor’s failure is an Acceptable
Insurance Default (as determined by the Special Servicer with the consent of the Directing Holder (unless a Control Termination
Event is continuing) and after consultation with the Risk Retention Consultation Party pursuant to Section 6.08(a)
(in each case, other than with respect to an Excluded Loan as to such party)) and only if the Trustee has an insurable interest
therein and such insurance is available to the Master Servicer or the Special Servicer, as the case may be, and, if available,
can be obtained at commercially reasonable rates. The Master Servicer and the Special Servicer shall be entitled to rely on insurance
consultants (at the applicable servicer’s expense) in determining whether any insurance is available at commercially reasonable
rates. Subject to Section 3.15(a) and the costs of such insurance being reimbursed or paid to the Special Servicer
as provided in the third-to-last sentence of this paragraph, the Special Servicer shall maintain (except to the extent that the
failure to maintain such insurance coverage is an Acceptable Insurance Default) for each REO Property (other than any Non-Serviced
Mortgaged Property) no less insurance coverage than was previously required of the Mortgagor under the related Mortgage Loan documents
unless the Special Servicer determines with the consent of the Directing Holder (if no Control Termination Event is continuing)
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) 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 may 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


 



    -193-


     


    




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 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 is not 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 and is then-available at commercially reasonable rates and the Trustee
has an insurable interest therein.


 


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 will be entitled to conclusively rely upon the certificates of
insurance in determining whether such policies contain Additional Exclusions), (B) request the Mortgagor to either purchase
insurance against the risks specified in the Additional Exclusions or provide an explanation as to its reasons for failing to
purchase such insurance and (C) notify the Special Servicer if it has knowledge that any Insurance Policy contains Additional
Exclusions or if it has knowledge (such knowledge to be based upon


 






    -194-


     


    

 


the Master Servicer’s compliance with the immediately
preceding clauses (A) and (B) above) that any Mortgagor fails to purchase the insurance requested to be purchased
by the Master Servicer pursuant to clause (B) above. In addition, upon the written request of the Risk Retention Consultation
Party with respect to any individual triggering event, the Special Servicer shall consult on a non-binding basis pursuant to Section 6.08(a)
with the Risk Retention Consultation Party (only with respect to a Specially Serviced Loan and other than with respect to
an Excluded Loan as to such party) within the same time period as it would obtain the consent of, or consult with, the Directing
Holder in connection with any such determination by the Special Servicer of an Acceptable Insurance Default. If the Special Servicer
determines in accordance with the Servicing Standard that such failure is not an Acceptable Insurance Default, the Special Servicer
shall notify the Master Servicer and the Master Servicer shall use efforts consistent with the Servicing Standard to cause such
insurance to be maintained. The Special Servicer (at the expense of the Trust) shall be entitled to rely on insurance consultants
in making such determinations. The Master Servicer shall be entitled to rely on insurance consultants (at the expense of such
Master Servicer) in determining whether Additional Exclusions exist. If the Special Servicer determines that such failure is an
Acceptable Insurance Default, the Special Servicer shall promptly deliver such conclusions in writing to the 17g-5 Information
Provider for posting to the 17g-5 Information Provider’s Website for those Mortgage Loans that (i) have one of the
ten (10) highest outstanding Stated Principal Balances of all of the Mortgage Loans then included in the Trust or (ii) comprise
more than 5% of the outstanding Stated Principal Balance of the Mortgage Loans then included in the Trust. Subject to the Servicing
Standard, during the period that the Special Servicer is evaluating the availability of such insurance or waiting for a response
from the Directing Holder, or to consult with the Risk Retention Consultation Party pursuant to Section 6.08(a), neither
the Master Servicer nor the Special Servicer will be liable for any loss related to its failure to require the Mortgagor to maintain
(or its failure to maintain) such insurance and will not be in default of its obligations as a result of such failure.


 


(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 has not 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 has 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 shall prepare and present, on behalf of itself, the


 






    -195-


     


    

 


Trustee and Certificateholders,
claims under any such blanket Insurance Policy in a timely fashion in accordance with the terms of such policy. Consistent with
subsection (a) above, the Special Servicer, to the extent consistent with the Servicing Standard, may maintain, earthquake
insurance on REO Properties (other than with respect to a Non-Serviced Mortgaged Property), provided coverage is available at
commercially reasonable rates, the cost of which shall be a Servicing Advance.


 


(ii)              
If the Master Servicer or the Special Servicer causes 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 be deemed to have satisfied its obligation to cause such
insurance to be maintained on the related Mortgaged Properties and REO Properties. If the Master Servicer or the Special Servicer
causes any Mortgaged Property or REO Property to be covered by such master single interest or force-placed Insurance Policy, the
Master Servicer shall pay 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) 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 (if no policy that complies with the provisions of Section 3.07(a)
has been maintained on the related Mortgaged Property or REO Property, and there has been one or more losses which would have
been covered by such policy had it been maintained) deposit into the Collection Account from its own funds the amount not otherwise
payable under the master single or force-placed interest policy because of such deductible clause, to the extent that any such
deductible exceeds the deductible limitation that pertained to the related Mortgage Loan, including any related Serviced Companion
Loan, or, in the absence of any such deductible limitation, the deductible limitation which is consistent with the Servicing Standard.


 


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


 






    -196-


     


    

 


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


 


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


 


(e)            
While any REO Property (other than with respect to an REO Property that formerly secured a Non-Serviced Mortgage Loan) is located
in a federally designated special flood hazard area, the Special Servicer shall cause to be maintained, to the extent available
at commercially reasonable rates (as determined by the Special Servicer (with the consent of the Directing Holder (if no Control
Termination Event is continuing) and in consultation with the Risk Retention Consultation Party pursuant to Section 6.08(a)
(in either such case, other than with respect to any Mortgage Loan that is an Excluded Loan as to such party)) in accordance
with the Servicing Standard), a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance
Administration in an amount representing coverage not less than the maximum amount of insurance which is available under the National
Flood Insurance Act of 1968, as amended. The cost of any such flood insurance with respect to an REO Property shall be an expense
of the Trust payable out of the related REO Account pursuant to Section 3.14(c) or, if the amount on deposit therein
is insufficient therefor, paid by the Master Servicer as a Servicing Advance and if determined to be nonrecoverable, the Master
Servicer shall pay out of general collections in the Collection Account.


 


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

Mortgage Loan) and any related


 






    -197-


     


    

 


Serviced Companion Loan that contains a provision in the nature of a “due-on-sale”
clause, which by its terms:


 


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


 


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


 


then,
for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement, the Special Servicer
(or, with respect to Non-Specially Serviced Loans, if mutually agreed to by the Master Servicer and the Special Servicer, the
Master Servicer (in a manner consistent with the Servicing Standard and subject to the consent of the Special Servicer)), on behalf
of the Trustee as the mortgagee of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or
related Companion Loan (x) to accelerate the payments thereon or (y) to withhold its consent to any sale or transfer,
consistent with the Servicing Standard or (b) waive any right to exercise such rights, provided that, (i)(A) if such
Mortgage Loan is not an Excluded Loan and no Control Termination Event is continuing, the Master Servicer or the Special Servicer,
as the case may be, shall obtain the prior written consent (or deemed consent pursuant to Section 6.08)of (x) in the
case of the Master Servicer, the Special Servicer and (y) in the case of the Special Servicer, the Directing Holder, and the Directing
Holder’s consent shall be deemed given ten (10) days after receipt (unless earlier objected to by the Directing Holder)
of the Special Servicer’s written analysis and recommendation with respect to such waiver together with such other information
reasonably requested by the Directing Holder and (B) if such Mortgage Loan is not an Excluded Loan, a Control Termination Event
is continuing and no Consultation Termination Event is continuing, the Special Servicer shall consult with the Directing Holder
and the Risk Retention Consultation Party pursuant to Section 6.08(a) and (ii) with respect to any Mortgage Loan
(x) with a Stated Principal Balance greater than $35,000,000, (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
in the same Crossed Mortgage Loan Group (in the case of a Crossed Underlying Loan) or together with all other Mortgage Loans with
the same Mortgagor (or an Affiliate thereof), that is one of the ten largest Mortgage Loans outstanding (by Stated Principal Balance),
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 Companion Loan Rating Agency Confirmations with respect to any Serviced Companion Loan
Securities, provided, however, that with respect to subclauses (x) and (y) of this subclause (iii),
such Mortgage Loan shall also have a Stated Principal Balance of at least $10,000,000 for such Rating Agency Confirmation requirement
to apply. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Holder
(regardless of whether an Operating Advisor Consultation Event is continuing), the Special Servicer shall consult with the Operating
Advisor (telephonically or electronically), on a non-binding basis, in connection with the related transactions involving proposed
Major Decisions that it is processing or for which its consent is required and consider


 






    -198-


     


    

 


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 VRR 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) if no Consultation Termination Event is continuing, Specially Serviced Loans;
and (ii) during a Consultation Termination Event, all Mortgage Loans, within the same time period as it would obtain the consent
of, or consult with, the Directing Holder with respect to the above described “due-on-sale” matters.


 


In
connection with any request for a Rating Agency Confirmation from a Rating Agency (or, with respect to any Serviced Companion
Loan Securities, the related rating agencies) pursuant to this Section 3.08(a), the Special Servicer shall (if not
already provided in accordance with Section 3.25) 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.


 


If
any Mortgage Loan (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan provides that such Mortgage Loan
or related Serviced Companion Loan may be assumed or transferred without the consent of the mortgagee; provided that certain conditions
are satisfied, then for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement,
(i) the Special Servicer, with respect to all Mortgage Loans (other than a Non-Serviced Mortgage Loan and other than as set forth
in clause (ii)) or related Serviced Companion Loans, on behalf of the Trustee as the mortgagee of record, shall determine
in accordance with the Servicing Standard whether such conditions have been satisfied, or, (ii) with respect to any Non-Specially
Serviced Loan, if such action is not a Major Decision or a Special Servicer Decision, the Master Servicer, on behalf of the Trustee
as mortgagee of record, shall make such determination with respect to whether such conditions have been satisfied.


 


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


 


(i)

the Mortgagor or principals of the Mortgagor; or


 


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


 


then,
for so long as such Mortgage Loan (and related Companion Loan, if applicable) is serviced under this Agreement, the Special Servicer
(or, with respect to Non-Specially Serviced Loans, if mutually agreed to by the Master Servicer and the Special Servicer,


 






    -199-


     


    

 


the
Master Servicer (in a manner consistent with the Servicing Standard and subject to the consent of the Special Servicer), on behalf
of the Trustee as the mortgagee of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or
related Companion Loan (x) to accelerate the payments thereon or (y) to withhold its consent to the creation of any
additional lien or other encumbrance, consistent with the Servicing Standard or (b) waive its right to exercise such rights,

the continuance of an Operating Advisor Consultation Event, the Special Servicer shall consult with the Operating Advisor if and
to the extent required pursuant to Section 6.08(a), (provided that in the case of clause (A), clause (B),
clause (C) and clause (D), 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, which may be in the form of an Asset Status Report,
and analysis and all information reasonably requested by the Directing Holder, the Risk Retention Consultation Party or the Operating
Advisor, as applicable, and reasonably available to the Special Servicer in order to grant or withhold such consent or conduct

$20,000,000; provided, however, that with respect to subclauses (A), (B), (C) and (D)
of this subclause (iii), such Mortgage Loan shall also have a Stated Principal Balance of at least $10,000,000
for such Rating Agency Confirmation requirement to apply. Notwithstanding anything herein to the contrary, with respect to any
Excluded Loan (other than a Non-Serviced Mortgage Loan) as to the Directing Holder, regardless of whether an Operating Advisor
Consultation Event is continuing, the Special Servicer shall consult with the Operating Advisor (telephonically or electronically),
on a non-binding basis, in connection with the related transactions involving proposed Major Decisions and consider alternative
actions


 






    -200-


     


    

 


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 VRR Interest, upon request
of the Risk Retention Consultation Party, the Special Servicer shall consult on a non-binding basis with the Risk Retention Consultation

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 Master Servicer or the Special
Servicer that is processing the related action shall (if not already provided in accordance with Section 3.25) 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.


 


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 Master Servicer or the
Special Servicer that is processing the related action 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 subject to satisfaction of certain conditions in the related Mortgage Loan documents and
subject to which there is no lender discretion required, then for so long as such Mortgage Loan or related Companion Loan is being
serviced under this Agreement, (i) the Special Servicer, with respect to all Mortgage Loans (other than a Non-Serviced Mortgage
Loan and other than as set forth in clause (ii)), and (ii) the Master Servicer with respect to Non-Specially Serviced Loans
not involving a Major Decision or a Special Servicer Decision on behalf of the Trustee as the mortgagee of record, shall determine
whether such conditions have been satisfied.


 


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


 


(d)           
Except as otherwise permitted by Section 3.08(a) and (b) and/or Section 3.18, neither the Master
Servicer nor the Special Servicer shall agree to modify, waive or amend any term of any Mortgage Loan and related Serviced Companion
Loan, as applicable, in connection with the taking of, or the failure to take, any action pursuant to this Section 3.08.
The

Master Servicer and the Special Servicer, as applicable, shall provide copies of any final waivers (except with respect to
provision of any such waivers to the 17g-5 Information Provider, exclusive of any Privileged Information) it effects pursuant
to Section 3.08(a) or (b) to each other and to the 17g-5 Information Provider with respect to each Mortgage
Loan, and shall notify the Trustee, the Certificate Administrator, each other and, subject to the terms of this Agreement, the
17g-5 Information Provider (for posting to the 17g-5 Information Provider’s Website in accordance with Section 3.13(c))

pursuant to Section 3.08(a) or (b) and shall forward thereto a copy of such agreement.


 


(e)            
Notwithstanding any other provision of this Agreement, the Special Servicer may not waive its rights or grant its consent (or
consent to the Master Servicer taking any such action) under any “due-on-sale” or “due-on-encumbrance”
clause relating to any Mortgage Loan without ((i) if no Control Termination Event is continuing and (ii) other than with respect
to any Excluded Loan as to such party) the consent of the Directing Holder (or (i) during a Control Termination Event, but while
no Consultation Termination Event is continuing, and (ii) other than with respect to any Excluded Loan as to such party, upon
consultation with the Directing Holder pursuant to Section 6.08) and, other than with respect to an Excluded Loan
as to such party, after consultation with the Risk Retention Consultation Party if and to the extent required pursuant to Section 6.08.
The Directing Holder will have ten (10) days after receipt of notice along with the Master Servicer’s or Special Servicer’s
recommendation and analysis with respect to such proposed waiver or proposed granting of consent and any additional information
the Directing Holder may reasonably request from the Special Servicer of a proposed waiver or consent under any “due-on-sale”
or “due-on-encumbrance” clause in which to grant or withhold its consent (provided that if the Special Servicer
fails to receive a response to such notice from the Directing Holder in writing within such period, then the Directing Holder
shall be deemed to have consented to such proposed waiver or consent).


 


(f)             
With respect to any Mortgagor request or other action on a Non-Specially Serviced Loan for matters that are Major Decisions or
Special Servicer Decisions, if the Master Servicer and the Special Servicer have mutually agreed to have the Master Servicer process
such Major Decision or Special Servicer Decision, the Master Servicer shall not agree to such Major Decision or Special Servicer
Decision without the prior written consent of the Special Servicer and, as applicable, the Directing Holder (which consent or
deemed consent shall be obtained by the Special Servicer). In connection with such consent, if the Master Servicer is processing
such Major Decision or Special Servicer Decision, the Master Servicer shall promptly provide the Special Servicer with written
notice of any request for such Major Decision or Special Servicer Decision, along with the Master Servicer’s written recommendation
and analysis, and all information in the Master Servicer’s possession that may be reasonably requested by the Special Servicer
in order to grant or withhold such consent; provided that in the event that the Special Servicer does not respond within
ten (10) days after receipt of such written notice and all such reasonably requested information, plus the time period provided
to any Serviced Companion Noteholder under a related Intercreditor Agreement, the Special Servicer’s consent to such Major
Decision or Special Servicer Decision shall be deemed granted.


 


(g)            
Notwithstanding the foregoing provisions of this Section 3.08, if the Special Servicer makes a determination under
Sections 3.08(a) or 3.08(b) that the applicable conditions in


 






    -202-


     


    

 


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).


 


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


 


Section 3.09      
Realization Upon Defaulted Loans and Companion Loans. (a)  Upon an event of default under the Mortgage Loan documents
related to a Serviced Whole Loan or a Mortgage Loan with mezzanine debt, the Master Servicer shall promptly provide written notice
to the related Companion Holder or mezzanine lender, as applicable, with a copy of such notice to the Special Servicer. The Special
Servicer shall, subject to subsections (b) through (d) of this Section 3.09 and Section 3.24,
subject to the Directing Holder’s and the Risk Retention Consultation Party’s respective rights pursuant to Section 6.08,
and any Companion Holder or mezzanine lender’s rights under the related Intercreditor Agreement (in the case of a Serviced
Whole Loan, on behalf of the holders of the beneficial interest of the related Companion Loan) or this Agreement, exercise reasonable
efforts, consistent with the Servicing Standard, to foreclose upon or otherwise acquire title to the related Mortgaged Property
or otherwise comparably convert (which may include an REO Acquisition) the ownership of property securing any Mortgage Loan (other
than any Non-Serviced Mortgage Loan) and related Companion Loan(s), if any, as come into and continue in payment default or material
non-monetary 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 suffers damage from an Uninsured Cause, the Master Servicer
or the Special Servicer is not 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 Special Servicer 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 incurred by the Special Servicer
in any such proceedings shall be advanced by the Master Servicer;


 






    -203-


     


    

 


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 incidental 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 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 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, such Companion Holders
constituted a single lender (taking into account the pari passu or subordinate nature of any related Companion Loan), to
take such actions as are necessary to bring such Mortgaged Property in compliance with such laws, and


 






    -204-


     


    

 


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


 


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


 


(d)           
If (i) the environmental testing contemplated by subsection (c) above establishes that either of the conditions
set forth in clauses (i) and (ii) of subsection (c) above of the first sentence thereof has not
been satisfied with respect to any Mortgaged Property securing a Defaulted Loan and, in the case of a Serviced Mortgage Loan,
any related Companion Loan, and (ii) there has been no breach of any of the representations and warranties set forth in or
required to be made pursuant to Section 6 of each of the Mortgage Loan Purchase Agreements for which the applicable Mortgage
Loan Seller could be required to repurchase such Defaulted Loan pursuant to Section 6 of the applicable Mortgage Loan Purchase
Agreement (or, in the case of a Guaranteed Seller, the related Guarantor could be required to make payments under their respective
payment guaranties in connection with a repurchase), 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 Holder and after consultation with the Risk Retention Consultation Party pursuant to Section 6.08(a)
((A) if no Control Termination Event is continuing and (B) other than with respect to any Excluded Loan as


 






    -205-


     


    

 


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 notify the Rating
Agencies, the Trustee, the Certificate Administrator, the Master Servicer, the Directing Holder and the Risk Retention Consultation
Party (in the case of the Directing Holder, while no Consultation Termination Event is continuing, and in the case of the Directing
Holder or the Risk Retention Consultation Party other than with respect to any Excluded Loan as to such party), in writing of
its intention to so release such Mortgaged Property and the bases for such intention, (ii) the Certificate Administrator
shall post such notice of the Special Servicer’s intention to so release such Mortgaged Property to the Certificate Administrator’s
Website pursuant to Section 3.13(b) and (iii) in addition to the prior written consent of the Directing Holder
as required above, the Holders of Certificates entitled to a majority of the Voting Rights consent or have been deemed to have
consented to such release within thirty (30) days of the Certificate Administrator’s posting such notice to the Certificate
Administrator’s Website (failure to respond by the end of such 30-day period being deemed consent of the Holders of the
Certificates). To the extent any fee charged by any Rating Agency in connection with rendering such written confirmation is not
paid by the related Mortgagor, such fee is to be an expense of the Trust; provided that the Special Servicer shall use
commercially reasonable efforts to collect such fee from the Mortgagor to the extent permitted under the related Mortgage Loan
documents.


 


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


 






    -206-


     


    

 


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


 


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


 


(b)           
From time to time as is appropriate for servicing or foreclosure of any Mortgage Loan (other than any Non-Serviced Mortgage Loan)
(and any related Companion Loan), the Master Servicer or the Special Servicer shall deliver to the Custodian a Request for Release
signed by a Servicing Officer. Upon receipt of the foregoing, the Custodian shall deliver the Mortgage File or any document therein
to the Master Servicer or the Special Servicer (or a designee), as the case may be. Upon return of such Mortgage File or such
document to the Custodian, or the delivery to the Trustee and the Custodian of a certificate of a Servicing Officer of the Master
Servicer or the Special Servicer, as the case may be, stating that such Mortgage Loan (and, in the case of a Serviced Whole Loan,
the related Companion Loan), was liquidated and that all amounts received or to be received in connection with such liquidation
which are required to be deposited into the Collection Account (including amounts related to the related Companion Loan, if applicable)
pursuant to Section 3.04(a) have been or will be so deposited, or that such Mortgage Loan has become an REO Property,
a copy of the Request for Release shall be released by the Custodian to the Master Servicer or the Special Servicer (or a designee),
as the case may be, with the original being released upon termination of the Trust.


 


(c)            
Within three (3) Business Days (or within such shorter period as delivery can reasonably be accomplished if the Special Servicer
notifies the Trustee of an exigency) of


 






    -207-


     


    

 


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 is not required to review such documents for their sufficiency
or enforceability.


 


With
respect to each Servicing Shift Whole Loan, on and after the related Servicing Shift Securitization Date, if pursuant to the related
Intercreditor Agreement and the related Non-Serviced PSA, and as appropriate for enforcing the terms of such Servicing Shift Whole
Loan, as applicable, the related Non-Serviced Master Servicer requests delivery to it of the original Mortgage Note, then the
Custodian shall release or cause the release of such original Mortgage Note to the related Non-Serviced Master Servicer or its
designee.


 


(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, Serviced
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,
Serviced Companion Loan or REO Loan shall cease to accrue if a Liquidation Event occurs with respect to the related Mortgage Loan,
except that if such Mortgage Loan is part of a Serviced Whole Loan and such Serviced Whole Loan continues to be serviced and administered
under this Agreement notwithstanding such Liquidation Event, then the applicable Servicing Fee shall continue to accrue and be
payable as if such Liquidation Event did not occur. The Servicing Fee shall be payable monthly, on a loan-by-loan basis, from
payments of interest on each Mortgage Loan, Companion Loan and REO Revenues


 






    -208-


     


    

 


allocable as interest on each REO Loan, and as otherwise
provided by Section 3.05(a). The Master Servicer shall be entitled to recover unpaid Servicing Fees in respect of
any Mortgage Loan, Companion Loan or REO Loan out of that portion of related payments, Insurance and Condemnation Proceeds, Liquidation
Proceeds and REO Revenues (in the case of an REO Loan) allocable as recoveries of interest, to the extent permitted by Section 3.05(a).
Except as set forth in the next two sentences, the third paragraph of this Section 3.11(a), Section 6.03,
Section 6.05 and Section 7.01(c), the right to receive the Servicing Fee may not be transferred in whole
or in part (except in connection with a transfer of all of the Master Servicer’s duties and obligations hereunder to a successor
servicer in accordance with the terms hereof). With respect to each Serviced Pari Passu Companion Loan, the Servicing Fee shall
be payable to the Master Servicer from amounts payable in respect of such Serviced Pari Passu Companion Loan, subject to the terms
of the related Intercreditor Agreement.


 


The
Master Servicer is entitled to retain, and is not 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) (x) 100% of Excess Modification Fees related to any modifications,
waivers, extensions or amendments of any Mortgage Loans (other than any Specially Serviced Loans) and any related Serviced Companion
Loans, to the extent not prohibited by the related Intercreditor Agreement; provided that such transactions are Master
Servicer Decisions; and, provided, further, that the Master Servicer shall receive 0% of any COVID Modification
Fees; (ii) 100% of all assumption application fees and other similar items received on any Mortgage Loans solely to the extent
the Master Servicer is processing the underlying transaction (including any related Serviced Companion Loan, to the extent not
prohibited by the related Intercreditor Agreement) (whether or not the consent of the Special Servicer is required); (iii) 100%
of any fee actually paid by a Mortgagor in connection with the defeasance of a Mortgage Loan (other than a Non-Serviced Mortgage
Loan) and any related Serviced Companion Loan (provided that 50% of the portion of any Excess Modification Fee or waiver
fee payable solely in connection with any modification, waiver, amendment or consent executed in connection with a defeasance
transaction with respect to a Non-Specially Serviced Loan for which the consent, processing or approval of the Special Servicer
is required under clause (xiii) of the definition of “Major Decision” (and specifically excluding any defeasance
fees), must be paid by the Master Servicer to the Special Servicer); (iv) 100% of assumption, waiver, consent and earnout fees,
and other similar fees (other than assumption application fees 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); provided that such transactions qualify
as Master Servicer Decisions; (v) 50% of all Excess Modification Fees and 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
on any Mortgage Loan (other than a Specially Serviced Loan) (including any related Serviced Companion Loan, to the extent
not prohibited by the related Intercreditor Agreement); provided that such transaction qualifies as a Major Decision or
Special Servicer Decision; (vi) 100% of charges by the Master Servicer collected for checks returned for insufficient funds related
to accounts held by the Master Servicer and (vii) 100% of charges for beneficiary statements or demands actually paid by the related
borrowers to the extent such beneficiary statements or demands were prepared by the Master Servicer. In addition, the Master Servicer
shall be entitled to retain as additional servicing compensation (other than with


 






    -209-


     


    

 


respect to a Non-Serviced Mortgage Loan) any
charges for processing Mortgagor requests, beneficiary statements or demands, fees in connection with defeasance, if any, and
other customary charges, and amounts collected for checks returned for insufficient funds, in each case only to the extent actually
paid by the related Mortgagor and is not 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 the Servicing Account 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 Excess 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 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.


 


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


 


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 its 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


 






    -210-


     


    

 


the Special Servicer may 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.  For the avoidance of doubt, 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.


 


(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 Serviced REO Loan. As to each Specially Serviced Loan and Serviced 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 Serviced REO Loan, as the case may be, and in the same manner as interest
is calculated on the Specially Serviced Loans or Serviced 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 Serviced REO Loan is computed. The Special Servicing Fee with respect to any Specially Serviced Loan or Serviced
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 directly 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. Nothing herein is intended to limit
the Special Servicer’s right to enter into a fee sharing agreement with the Directing Certificateholder or any other party.
The Special Servicer shall not be entitled to any Special Servicing Fees with respect to a Non-Serviced Mortgage Loan.

Servicer is processing the underlying assumption related transaction, (iii) 50% of any Excess Modification Fees or waiver fees

or Special Servicer Decision, (iv) 100% of all assumption, waiver, consent and earnout fees, pursuant to Section 3.08
and Section 3.18 or other actions performed in connection with this Agreement on the Specially Serviced Loans

other similar fees paid by the related Mortgagor, (v) (A) 50% of all waiver fees, assumption fees, consent fees pursuant
to Section 3.08 or Section 3.18 and earnout fees received in each case with respect to all Mortgage Loans
(including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) (excluding
any Non-Serviced Mortgage Loan) that are not Specially Serviced Loans; provided that such transaction qualifies as a Major
Decision or Special Servicer Decision and (B) 0% of all assumption fees, consent fees and earnout fees received with respect to
al Mortgage Loans (including the Serviced Companion Loan(s), to the extent not prohibited by the related Intercreditor Agreement)

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 are not 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 the Loss of Value Reserve Fund in accordance with Section 3.06(b)
(but only to the extent of the Net Investment Earnings, if any, with respect to such account for the period from and including
the prior Distribution Date to and including the P&I Advance Date related to such Distribution Date). In addition, the Special
Servicer shall also be entitled to retain as additional servicing compensation (other than with respect to any Non-Serviced Mortgage
Loan) reasonable review fees in connection with any Mortgagor request to the extent such review fees are not prohibited under
the related Mortgage Loan documents, and only to the extent actually paid by the related Mortgagor. The Special Servicer shall
also be entitled to additional servicing compensation in the form of a Workout Fee with respect to each Corrected Loan at the
Workout Fee Rate on such Corrected Loan for so long as it remains a Corrected Loan; provided, however, that after
receipt by the Special Servicer of Workout Fees with respect to such Corrected Loan in an amount equal to $25,000, any Workout
Fees in excess of such amount shall be reduced by the Excess Modification Fee Amount; provided, further, however,
that if the Workout Fee collected over the course of such workout calculated at the Workout Fee Rate is less than $25,000, then
the Special Servicer shall be entitled to an amount from the final payment on the related Corrected Loan (including any related
Serviced Companion Loan) that would result in the total Workout Fees payable to the Special Servicer in respect of that Corrected
Loan (including any related Serviced Companion Loan) to be $25,000. The Workout Fee shall be reduced (but not below zero) pursuant
to the preceding sentence with respect to each collection on such Corrected Loan from which fee would otherwise be payable until
an amount equal to such Excess Modification Fee Amount has been deducted in full. The Workout Fee with respect to any Corrected
Loan will cease to be payable if such loan again becomes a Specially Serviced Loan; provided that a new Workout Fee will
become payable if and when such Specially Serviced Loan again becomes a Corrected Loan. The Special Servicer shall not be entitled
to any Workout Fee with respect to a Non-Serviced Mortgage Loan. If the Special Servicer is terminated (other than for cause)
or resigns, it shall retain the right to receive any and all Workout Fees payable in respect of Mortgage Loans or any related
Companion Loan that became Corrected Loans prior to the time of that termination or resignation except the Workout Fees will no
longer be payable if


 






    -212-


     


    

 


the Corrected Loan subsequently becomes a Specially Serviced Loan. If the Special Servicer resigns or is
terminated (other than for cause), it will receive any Workout Fees payable on Specially Serviced Loans for which the resigning
or terminated Special Servicer had determined to grant a forbearance or cured the event of default through a modification, restructuring
or workout negotiated by the Special Servicer and evidenced by a signed writing, but which had not as of the time the Special
Servicer resigned or was terminated become a Corrected Loan solely because the Mortgagor had not had sufficient time to make three
consecutive timely Periodic Payments and which subsequently becomes a Corrected Loan as a result of the Mortgagor making such
three consecutive timely Periodic Payments except the Workout Fees will no longer be payable if the Corrected Loan subsequently
becomes a Specially Serviced Loan. The successor special servicer shall not be entitled to any portion of such Workout Fees. The
Special Servicer shall not be entitled to receive any Workout Fees after termination for cause. A Liquidation Fee will be payable
with respect to each Specially Serviced Loan (other than a Non-Serviced Mortgage Loan) or REO Property (other than a Non-Serviced
Mortgaged Property) as to which the Special Servicer receives any Liquidation Proceeds or Insurance and Condemnation Proceeds
subject to the exceptions set forth in the definition of Liquidation Fee (such Liquidation Fee to be paid out of such Liquidation
Proceeds, Insurance and Condemnation Proceeds). If, however, Liquidation Proceeds or Insurance and Condemnation Proceeds are received
with respect to any Corrected Loan and the Special Servicer is properly entitled to a Workout Fee, such Workout Fee will be payable
based on and out of the portion of such Liquidation Proceeds and Insurance and Condemnation Proceeds that constitute principal
and/or interest on such Mortgage Loan. Notwithstanding anything herein to the contrary, the Special Servicer shall only be entitled
to receive a Liquidation Fee or a Workout Fee, but not both, with respect to proceeds on any Mortgage Loan. 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 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.


 


(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

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 (including 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, 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).
The Master Servicer may not waive any fee or compensation due to the Special Servicer without the Special Servicer’s consent.
The Special Servicer may not waive any fee or compensation due to the Master Servicer without the Master Servicer’s consent.


 


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

Servicing Shift Whole Loan and the Non-Serviced Special Servicer were replacing the Special Servicer as the successor Special
Servicer with respect to such Servicing Shift Whole Loan.


 


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

Servicer, the CREFC® Appraisal Reduction Amount Template. In no event shall any report described in this subsection be required
to reflect information that has not been collected by or delivered to the Master Servicer, or any payments or collections not
received by the Master Servicer, as of the close of business on the Business Day prior to the Business Day on which the report
is due.


 


Not
later than 5:00 p.m. (New York City time) two (2) calendar days following each Distribution Date (provided that if the second
calendar day is not a Business Day, then the immediately succeeding Business Day) beginning April 2021, the Master Servicer shall
deliver to the Certificate Administrator the CREFC® Schedule AL File in EDGAR-Compatible Format; provided
that the Master Servicer will have no obligation to prepare or deliver any such CREFC® Schedule AL File unless
the Depositor has delivered the items required by Section 2.01(i). If the CREFC® Schedule AL File is
not provided by 5:00 p.m. (New York City time) on the Master Servicer Remittance Date, the Certificate Administrator shall
request such CREFC® Schedule AL File from the Master Servicer via e-mail at NoticeAdmin@midlandls.com, with a copy
to the Depositor at chuck.lee@credit-suisse.com. In preparing the CREFC® Schedule AL File and any Schedule AL Additional
File for any given Distribution Date, and without any due diligence, investigation or verification, the Master Servicer may conclusively
rely, absent manifest error, on the content, completeness, accuracy and compliance with any applicable requirements of Items 1111(h)
and 1125 of Regulation AB and Item 601(b) of Regulation S-K under the Securities Act as in effect on the Closing Date of the Initial
Schedule AL File, any Initial Schedule AL Additional File and Annex A-1 to the Prospectus. The Master Servicer may concurrently
with the delivery of the related CREFC® Schedule AL File, deliver any related Schedule AL Additional File in EDGAR-Compatible
Format to the Certificate Administrator. The CREFC® Schedule AL File and the Schedule AL Additional File shall
each be a single file. Neither the Certificate Administrator nor the Master Servicer shall be required to combine multiple CREFC®
Schedule AL Files or Schedule AL Additional Files, unless, solely with respect to the Master Servicer, multiple Sub-Servicers
prepare and submit such CREFC® Schedule AL Files or Schedule AL Additional Files to the Master Servicer. The Certificate
Administrator is not required to review, redact, reconcile, edit or verify the content, completeness or accuracy of the information
contained in any CREFC® Schedule AL File or any Schedule AL Additional File. The Certificate Administrator shall
not be deemed to have actual knowledge of the contents of any CREFC® Schedule AL File or Schedule AL Additional
File solely by its receipt thereof.

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


 


(e)            
The Special Servicer shall deliver to the Master Servicer the reports and information required of the Special Servicer pursuant
to Section 3.12(b) and Section 3.12(c), and the Master Servicer shall deliver or make available to the
Certificate Administrator the reports and data files set forth in Section 3.12(b). The Master Servicer may, absent
manifest error, conclusively rely on the reports and/or data to be provided by the Special Servicer pursuant to Section 3.12(b)
and Section 3.12(c). The Certificate Administrator may, absent manifest error, conclusively rely on the reports
and/or data to be provided by the Master Servicer pursuant to Section 3.12(b). In the case of information or reports
to be furnished by the Master Servicer to the Certificate Administrator pursuant to Section 3.12(b), to the extent
that such information or reports are, in turn, based on information or reports to be provided by the Special Servicer pursuant
to Section 3.12(b) or Section 3.12(c) and to the extent that such reports are to be prepared and delivered
by the Special Servicer pursuant to Section 3.12(b) or Section 3.12(c), the Master Servicer will 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 will not be in default hereunder due to a delay in providing the
reports required by Section 3.12(b) caused by the Special Servicer’s failure to timely provide any information
or report required under Section 3.12(b) or Section 3.12(c).


 


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


 


(g)            
Unless otherwise specifically stated herein, if the Master Servicer or the Special Servicer is required to deliver any statement,
report or information under any provisions of this Agreement, the Master Servicer or the Special Servicer, as the case may be,
may satisfy such obligation by (x) physically delivering a paper copy of such statement, report or information, (y) delivering
such statement, report or information in a commonly used electronic format or (z) except with respect to information to be
provided to the Certificate Administrator or any Companion Holder and, if no Consultation Termination Event is continuing, the
Directing Holder, making such statement, report or information available on the Master Servicer’s or the Special Servicer’s
Internet website, unless this Agreement expressly specifies a particular method of delivery.


 






    -220-


     


    

 


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


 


Section 3.13      
Access to Certain Information. (a)  Each of the Master Servicer and the Special Servicer shall provide or cause
to be provided to the Certificate Administrator, and the Certificate Administrator shall afford access to any Mortgage Loan Seller
and to any Certificateholder that is a federally insured financial institution, the OCC, the FDIC, the Board of Governors of the
Federal Reserve System of the United States of America and the supervisory agents and examiners of such boards and such corporations,
and any other federal or state banking or insurance regulatory authority that may exercise authority over any such Certificateholder,
and to each Holder of a Non-Registered Certificate, access to any documentation or information regarding the Mortgage Loans (other
than any Non-Serviced Mortgage Loan) and, in the case of a Mortgage Loan that is a portion of a Serviced Whole Loan, the related
Companion Loan, and the Trust within its control which may be required by applicable law. At the election of the Master Servicer,
the Special Servicer or the Certificate Administrator, such access may be afforded to such Person identified above by the delivery
of copies of information as requested by such Person and the Master Servicer, the Special Servicer or the Certificate Administrator
shall be permitted to require payment (other than from the Directing Holder (if no Consultation Termination Event is continuing)
and the Trustee and the Certificate Administrator on its own behalf or on behalf of the Certificateholders, as applicable) of
a sum sufficient to cover the reasonable out-of-pocket costs incurred by it in making such copies. Such access shall (except as
described in the preceding sentence) be afforded without charge but only upon reasonable prior written request and during normal
business hours at the offices of the Certificate Administrator or the Custodian.


 


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


 






    -221-


     


    

 


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.


 


Upon
the reasonable request of any Certificateholder or Certificate Owner (or with respect to any Subordinate Companion Loan, the holder
of such Subordinate Companion Loan) that has delivered an Investor Certification to the Master Servicer or the Special Servicer,
as applicable, the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially
Serviced Loans), as applicable, may provide (or forward electronically) at the expense of such Certificateholder or holder of
such 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 AB Whole Loan, if requested by the holder of a Subordinate Companion Loan)
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 Subordinate Companion
Loan, as applicable, may have under this Agreement. In addition, upon the reasonable request of any Controlling Class Certificateholder
identified to the Master Servicer (in the case of a Non-Specially Serviced Loan) or the Special Servicer (in the case of a Specially
Serviced Loan) to the Master Servicer’s or the Special Servicer’s reasonable satisfaction and if the requested information
is in the Master Servicer’s or the Special Servicer’s possession, the Master Servicer or the Special Servicer, as
applicable, shall provide or make available (or forward electronically) to such Controlling Class Certificateholder (at the
expense of such Controlling Class Certificateholder) any Excluded Information (available to Privileged Persons through the
Certificate Administrator’s Website but not accessible to such Controlling Class Certificateholder through the Certificate
Administrator’s Website on account of it constituting Excluded Information) relating to any Excluded Controlling Class Loan
with respect to which such Controlling Class Certificateholder is not an Excluded Controlling Class Holder; provided
that, in connection therewith, the Master Servicer or the Special Servicer may require a written confirmation executed by
the requesting Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special Servicer,
generally to the effect that such Person is a Controlling Class Certificateholder, will keep such Excluded Information confidential
and is not a Borrower Party, upon which the Master Servicer or the Special Servicer may conclusively rely. In addition, the Master
Servicer and the Special Servicer may conclusively rely on delivery from a Controlling Class Certificateholder of an investor
certification substantially in the form of Exhibit P-1E that such Controlling Class Certificateholder is not
an Excluded Controlling Class Holder with respect to a particular Mortgage Loan.

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

provided
that with respect to a Control Termination Event or a Consultation Termination Event deemed to exist due solely to the existence

The
Certificate Administrator shall, in addition to posting the applicable notices on the “U.S. Risk Retention Special Notices”

the Operating Advisor, the Certificate Administrator and the Trustee in physical form of an investor certification substantially
in the


 






    -226-


     


    

 


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


 


Notwithstanding
anything herein to the contrary, each of the Master Servicer, the Special Servicer, the Operating Advisor and the Certificate
Administrator shall conclusively assume that the Directing Holder and all beneficial owners of the Certificates of the Controlling
Class are not Excluded Controlling Class Holders except to the extent that the Master Servicer, the


 






    -227-


     


    

 


Special Servicer,
the Operating Advisor or the Certificate Administrator, as applicable, has received a notice substantially in the form of Exhibit
P-1E from the Directing Holder or a Controlling Class Certificateholder that it has become an Excluded Controlling Class Holder.
None of the Master Servicer, the Special Servicer, the Operating Advisor or the Certificate Administrator shall be liable for
any communication to the Directing Holder or a Controlling Class Certificateholder that is an Excluded Controlling Class Holder
or disclosure of any information relating to an Excluded Controlling Class Loan (including any related Excluded Information
delivered to the Certificate Administrator for posting to the Certificate Administrator’s Website) if the Master Servicer,
the Special Servicer, the Operating Advisor or the Certificate Administrator, as applicable, did not receive prior written notice
that the related Mortgage Loan is an Excluded Controlling Class Loan and/or, with respect to any related Excluded Information
posted on the Certificate Administrator’s Website, such information was not delivered to the Certificate Administrator in
accordance with Section 3.30.


 


Each
of the Master Servicer, the Special Servicer, the Operating Advisor and the Certificate Administrator shall conclusively rely
on delivery from the Directing Holder or a Controlling Class Certificateholder of an Investor Certification substantially
in the form of Exhibit P-1B that it is not or is no longer an Excluded Controlling Class Holder. To the extent the
Directing Holder or a Controlling Class Certificateholder receives access pursuant to this Agreement to any Excluded Information
on the Certificate Administrator’s Website or otherwise receives access to such Excluded Information, such Directing Holder
or Controlling Class Certificateholder shall be deemed to have agreed that it (i) will not directly or indirectly provide
any such Excluded Information to (A) the related Borrower Party, (B) any related Excluded Controlling Class Holder,
(C) any employees or personnel of such Directing Holder or Controlling Class Certificateholder or any of its 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 the VRR 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 any Officer’s Certificates delivered by the Trustee,
the Master Servicer or the Special Servicer, supporting any determination that any Advance was (or, if made, would be) a Nonrecoverable
Advance, but in each case other than information with respect to such Mortgage Loan that is aggregated with information of other
Mortgage Loans at a pool level), on the Certificate Administrator’s Website or otherwise receives access to such information,
such Risk Retention Consultation Party or Holder of a VRR Interest 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 the VRR 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


 






    -228-


     


    

 


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.


 


The
Certificate Administrator makes no representation or warranty as to the accuracy or completeness of any report, document or other
information made available on its Internet website or its filing of such information, 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

to orally communicate with the Rating Agencies regarding any of the Mortgage Loan documents and any other matter related to the
Mortgage Loans, the related Mortgaged Properties, the related Mortgagors or any other matters relating to this Agreement or related
Intercreditor Agreement; provided that such party summarizes the information provided to the Rating Agencies in such communication

In
connection with the delivery by the Master Servicer or the Special Servicer, as applicable, to the 17g-5 Information Provider

or (ii) is simultaneously provided to the 17g-5 Information Provider.


 


(g)            
Without limiting the Operating Advisor’s consultation rights pursuant to Section 6.08, the Special Servicer

Status Reports and approved or deemed approved Major Decision Reporting Packages (only with respect to any Specially Serviced
Loans) and after an Operating Advisor Consultation Event, Asset Status Reports and Major Decision Reporting Packages. In addition,
the Special Servicer, subject to the limitations on delivery of Privileged Communications, shall deliver to the Operating Advisor
such reports and other information produced or otherwise made available by the Special Servicer to the Directing Holder or the

Reports that are not Final Asset Status Reports), or Certificateholders generally, requested by the Operating Advisor in support
of the performance of its obligations under this Agreement in electronic format.


 


(h)            
None of the foregoing restrictions in this Section 3.13 or otherwise in this Agreement shall prohibit or restrict
oral or written communications, or providing information, between the Master Servicer, the Operating Advisor, the Asset Representations
Reviewer or the Special Servicer, on the one hand, and any Rating Agency or NRSRO, on the other hand, with regard to (i) such
Rating Agency’s or NRSRO’s review of the ratings it assigns to the Master Servicer, the Operating Advisor, the Asset
Representations Reviewer or the Special Servicer, as applicable, (ii) such Rating Agency’s or NRSRO’s approval
of the Master Servicer, the Operating Advisor, the Asset Representations Reviewer or the Special Servicer, as applicable, as a

of the Master Servicer’s, the Operating Advisor, the Asset Representations Reviewer’s or the Special Servicer’s,
as applicable, servicing operations in general; provided that the Master Servicer, the Operating Advisor, the Asset Representations
Reviewer or the Special Servicer, as applicable, shall not provide any information relating to the Certificates or the Mortgage
Loans to any Rating Agency or NRSRO in connection with such review and evaluation by such Rating Agency or NRSRO unless (x) Mortgagor,
property and other deal specific identifiers are redacted; (y) such information has already been provided to the 17g-5 Information
Provider and has been uploaded on to the 17g-5 Information Provider’s Website; or (z) such Rating Agency has confirmed in
writing to the Master Servicer, the Operating Advisor, the Asset Representations Reviewer or the Special Servicer, as applicable,
that it does not intend to use such information in undertaking credit rating surveillance for any Class of Certificates; provided,
however, that the Rating Agencies may use information delivered in reliance on the certification provided in this clause (z)
for any purpose to the extent it is publicly available (unless the availability results from a breach of this Agreement or
any other confidentiality agreement to which such Rating Agency is subject) 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
such Rating Agency has access to).


 


(i)             
The costs and expenses of compliance with this Section 3.13 by any party to this Agreement shall be borne by such
party and are not additional expenses of the Trust.


 






    -234-


     


    

 


Section 3.14      
Title to REO Property; REO Account. (a)  If title to any Mortgaged Property is acquired directly or indirectly
through a single member limited liability company established for such purpose (and thus becomes REO Property), the deed or certificate
of sale must 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 an 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 qualifying 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 Lower-Tier REMIC of such REO Property subsequent to the close of the third calendar year following the
year in which acquisition occurred will not cause an Adverse REMIC Event to occur. If the Special Servicer is granted or not denied
the REO Extension contemplated by clause (i) of the immediately preceding sentence or obtains the Opinion of Counsel
contemplated by clause (ii) of the immediately preceding sentence, the Special Servicer shall sell such REO Property
within such longer period as is permitted by such REO Extension or such Opinion of Counsel, as the case may be. Any expense incurred
by the Special Servicer in connection with its being granted the REO Extension contemplated by clause (i) of the second
preceding sentence or its obtaining the Opinion of Counsel contemplated by clause (ii) of the second preceding sentence,
shall be an expense of the Trust payable out of the Collection Account pursuant to Section 3.05(a).


 


(b)           
The Special Servicer shall segregate and hold all funds collected and received in connection with any REO Property separate and
apart from its own funds and general assets. If an REO Acquisition shall occur, the Special Servicer shall establish and maintain
one or more REO Accounts, held on behalf of the Trustee for the benefit of the Certificateholders and, if applicable, on behalf
of any related Companion Holder(s), as applicable, as their interest shall appear, and the Trustee (as holder of the Lower-Tier
Regular Interests), for the retention of revenues and other proceeds derived from each REO Property. The REO Account shall be
an Eligible Account. The Special Servicer shall deposit, or cause to be deposited, in the REO Account, within 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 or the Loss of Value Reserve Fund 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


 






    -235-


     


    

 


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, with respect to a Serviced Companion
Loan, on the Business Day preceding each Serviced Whole Loan Remittance Date) or (y) two (2) Business Days after such amounts
are received and properly identified, the Special Servicer shall withdraw from the REO Account and remit to the Master Servicer,
which shall deposit into the Collection Account (or the Companion Distribution Account, as applicable), the aggregate of all amounts
received in respect of each REO Property during the one-month period ending on such Determination Date, net of (i) any withdrawals
made out of such amounts pursuant to the preceding sentence and (ii) Net Investment Earnings on amounts on deposit in the
REO Account; provided, however, that the Special Servicer may retain in such REO Account, in accordance with the
Servicing Standard, such portion of such balance as may be necessary to maintain a reasonable reserve for repairs, replacements,
leasing, management and tenant improvements and other related expenses for the related REO Property. In addition, on or prior
to the day the Special Servicer remits funds as provided in this Section 3.14(c) (or with respect to a Serviced Companion
Loan, on the Business Day preceding each Serviced Whole Loan Remittance Date), the Special Servicer shall provide the Master Servicer
with a written accounting of amounts remitted to the Master Servicer for deposit in the Collection Account, as applicable, on
such date. The Master Servicer shall apply all such amounts as instructed by the Special Servicer on the Determination Date (or
with respect to a Serviced Companion Loan, on each Serviced Whole Loan Remittance Date) for the related Distribution Date.


 


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


 


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








    -236-


     


    

 


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
applicable REO Account all revenues received by it with respect to each REO Property and the related REO Loan, and shall withdraw
from the REO Account, to the extent of amounts on deposit therein with respect to such REO Property, funds necessary for the proper
operation, management, leasing and maintenance of such REO Property, including, without limitation:


 


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


 


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


 


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


 


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


 


To
the extent that amounts on deposit in the REO Account in respect of any REO Property are insufficient for the purposes set forth
in clauses (i) through (iv) above with respect to such REO Property, the Master Servicer (subject to receiving
notice from the Special Servicer in accordance with the procedures set forth elsewhere in this Agreement) shall advance from its
own funds such amount as is necessary for such purposes unless (as evidenced by an Officer’s Certificate delivered to the
Trustee, the Special Servicer, the Depositor, the Certificate Administrator and the Directing Holder (with respect to the Directing
Holder, other than with respect to an Excluded Loan as to such party, and if no Consultation Termination Event is continuing))
such advances would, if made, constitute Nonrecoverable Servicing Advances.


 


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


 


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


 


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


 


(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, if applicable, became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or


 


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


 






    -237-


     


    

 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


(iii)              
If any Mortgage Loan not subject to an Intercreditor Agreement becomes a Specially Serviced Loan, or if the related Companion
Holder or related mezzanine lender, as applicable, for any such Mortgage Loan subject to an Intercreditor Agreement has not previously
exercised the option to purchase the Mortgage Loan pursuant to the previous paragraph, the Special Servicer may offer to sell
to any Person any Specially Serviced Loan (to the extent consistent with any related Intercreditor Agreement and Section 3.16(d))
or may offer to purchase any Specially Serviced Loan, if and when the Special Servicer determines, consistent with the Servicing
Standard, that such a sale would be in the best economic interests of the Certificateholders or, if applicable, the Certificateholders
and the Serviced Companion Noteholder(s) (as a collective whole as if the Trust and the Serviced Companion Loan Noteholder(s)
constituted a single lender), on a net present value basis. In the case of any Non-Serviced Mortgage Loan, under certain limited
circumstances permitted under the related Intercreditor Agreement, to the extent that such Non-Serviced Mortgage Loan is not sold
together with the related Non-Serviced Companion Loan by the applicable Non-Serviced Special Servicer for the related Non-Serviced
Whole Loan, the Special Servicer will be entitled to sell (with the consent of the Directing Certificateholder and after consulting
with the Risk Retention Consultation Party pursuant to Section 6.08(a), in each case, if no Control Termination Event
is continuing and other than in respect of 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 the Special
Servicer shall be entitled to a Liquidation Fee to the same extent that the Special Servicer would be entitled to such Liquidation
Fee had such Non-


 






    -239-


     


    

 


Serviced Mortgage Loan been a Serviced Mortgage Loan. The Special Servicer is required to give the Trustee, the
Certificate Administrator, the Master Servicer, the Operating Advisor, the Directing Holder and the Risk Retention Consultation
Party (in the case of the Directing Holder and the Risk Retention Consultation Party, other than in respect of any Excluded Loan
as to such party) not less than ten (10) Business Days’ prior written notice of its intention to sell any Defaulted Loan,
in which case, subject to Section 3.16(a)(iv), the Special Servicer is required to accept the highest offer received
from any person for such Specially Serviced Loan in an amount at least equal to the outstanding principal balance plus all accrued
and unpaid interest and outstanding costs and expenses and certain other amounts pursuant to this Agreement (the “Par
Purchase Price”) or, at its option, if it has received no offer at least equal to the Par Purchase Price therefor, purchase
such Specially Serviced Loan at such Par Purchase Price.


 


(iv)              
(A)  In the case of a Specially Serviced Loan as to which a default has occurred and is continuing, in the absence of
any offer at least equal to the Par Purchase Price pursuant to clause (iii) above (or purchase by the Special Servicer
for such price), the Special Servicer shall, subject to subclause (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 highest offeror
is a Person other than an Interested Person. In determining whether any offer from a Person other than an Interested Person constitutes
a fair price for any Defaulted Loan or REO Property, the Special Servicer shall take into account (in addition to the results
of any Appraisal, updated Appraisal or narrative appraisal that it may have obtained pursuant to this Agreement within the prior
6 months), among other factors, the period and amount of the occupancy level and physical condition of the related Mortgaged Property
and the state of the local economy. If the offeror is an Interested Person, the Trustee (based upon updated Appraisals ordered
by the Special Servicer and received by the Trustee (or ordered by the Trustee if the Special Servicer or any of its Affiliates
is an Interested Person)) shall determine the fair price unless (i) the offer is equal to or greater than the applicable
Par Purchase Price and (ii) the offer is the highest offer received; provided, however, that no offer from
an Interested Person will constitute a fair price unless (A) it is the highest offer received and (B) if the offer is less than
the applicable Par Purchase Price, at least two other offers are received from independent third parties, and any such determination
by the Trustee shall be binding upon all parties. The Trustee shall act in a commercially reasonable manner in making such determination.
In determining whether any offer received from an Interested Person represents a fair price for any such Defaulted Loan, the Trustee
shall rely on the most recent Appraisal (or update of such Appraisal) of the related Mortgaged Property conducted in accordance
with this Agreement within the preceding 6-month period or, in the absence of any such Appraisal, on a new Appraisal. Except as
provided in the following paragraph, the cost of any Appraisal will be covered by, and will be reimbursable as, a Servicing Advance.


 


Notwithstanding
anything contained in the preceding paragraph to the contrary, if the Trustee is required to determine whether a cash offer by
an Interested Person constitutes a fair price and the offer is less than the Par Purchase Price, the Trustee may, at its option,
(at the expense of the Interested Person) designate an independent third party expert in real estate or commercial mortgage loan
matters with at least five (5) years’ experience in valuing loans similar to the subject Mortgage Loan or Serviced
Whole Loan, as the case


 






    -240-


     


    

 


may be, that has been selected with reasonable care by the Trustee to determine if such cash offer constitutes
a fair price for such Mortgage Loan or Serviced Whole Loan. If the Trustee designates such a third party to make such determination,
the Trustee may rely conclusively upon such third party’s determination. The reasonable fees of, and the costs of all Appraisals,
inspection reports and broker opinions of value incurred by any such third party shall be covered by, and shall be reimbursable,
from the offering Interested Person and the Special Servicer shall use efforts consistent with the Servicing Standard to collect
payment from such Interested Person. If such expense is not paid by the applicable Interested Person within thirty (30) days of
demand for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing Advance (provided
that the Trustee shall not engage a third party expert whose fees exceed a commercially reasonable amount as determined by
the Trustee) but the Special Servicer shall continue to use efforts consistent with the Servicing Standard to collect such amounts
from the applicable Interested Person. Neither the Trustee, in its individual capacity, nor any of its Affiliates may make an
offer for or purchase any Defaulted Loan.


 


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


 






    -241-


     


    

 


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


 


(b)           
(i)  (A)  The Special Servicer may purchase any REO Property at the Par Purchase Price therefor (in the case
of a Serviced Whole Loan, such purchase shall be a purchase of the entire REO Property, including the portion relating to the
related Companion Loan). The Special Servicer may also offer to sell to any Person any REO Property (in the case of a Serviced
Whole Loan, such sale shall be a sale of the entire REO Property, including the portion relating to the related Companion Loan),
if and when the Special Servicer determines, consistent with the Servicing Standard, that such a sale would be in the best economic
interest of the Trust and the related Companion Holders. The Special Servicer shall give the Trustee, the Master Servicer, each
Companion Holder, the Certificate Administrator, the Directing Holder and the Risk Retention Consultation Party (in the case of
the Directing Holder and the Risk Retention Consultation Party, other than in respect of an Excluded Loan as to such party and,
in the case of the Directing Holder, while no Consultation Termination Event is continuing) not less than ten (10) days’
prior written notice of its intention to (i) purchase any REO Property at the Par Purchase Price therefor or (ii) sell
any REO Property, in which case the Special Servicer shall accept the highest offer received from any Person for any REO Property
in an amount at least equal to the Par Purchase Price therefor. To the extent permitted by applicable law, and subject to the
Servicing Standard, the Master Servicer, an Affiliate of the Master Servicer, the Special Servicer or an Affiliate of the Special
Servicer, or an employee of either of them may act as broker in connection with the sale of any REO Property and may retain from
the proceeds of such sale a brokerage commission that does not exceed the commission that would have been earned by an independent
broker pursuant to a brokerage agreement entered into at arm’s length.


 


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


 


(C)     
The Special Servicer is not required 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, in either case, as a


 






    -242-


     


    

 


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,
in either case, as a collective whole (taking into account the subordinate or pari passu nature of any Serviced Companion
Loans) (for example, if the prospective buyer making the lower offer is more likely to perform its obligations, or the terms offered
by the prospective buyer making the lower offer are more favorable); provided that the offeror is not the Special Servicer
or a Person that is an Affiliate of the Special Servicer.


 


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


 


(ii)              
Subject to the Servicing Standard, the Special Servicer shall act on behalf of the Trust and the related Companion Holders in
negotiating and taking any other action necessary or appropriate in connection with the sale of any REO Property, including the
collection of all amounts payable in connection therewith. A sale of any REO Property shall be without recourse to, or representation
or warranty by, the Trustee, the Depositor, the Master Servicer, the Special Servicer, the Certificate Administrator, the Operating
Advisor, the Asset Representations Reviewer 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, the Asset Representations Reviewer nor the Trustee will have any liability to the Trust
or any Certificateholder or


 






    -243-


     


    

 


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 any Serviced Whole Loan, such determination shall be made by the Trustee
if the offeror is an Interested Person. Notwithstanding the foregoing, the Special Servicer shall not sell the related Mortgage
Loan together with the related Serviced Pari Passu Companion Loan(s) if it becomes a defaulted Whole Loan without the written
consent of the holder of the related Serviced Pari Passu Companion Loan (provided that such consent is not required if
the holder of the Serviced Pari Passu Companion Loan is the Mortgagor or an Affiliate of the Mortgagor) unless the Special Servicer
has delivered to the holder of the related Serviced Pari Passu Companion Loan: (a) at least fifteen (15) Business Days prior written
notice of any decision to attempt to sell such Serviced Whole Loan; (b) at least ten (10) days prior to the permitted sale date,
a copy of each bid package (together with any material amendments to such bid packages) received by the Special Servicer in connection
with any such proposed sale; (c) at least ten (10) days prior to the proposed sale date, a copy of the most recent Appraisal for
such Serviced Pari Passu Whole Loan, and any documents in the servicing file reasonably requested by the holder of the related
Serviced Pari Passu Companion Loan that are material to the sale price of the Serviced Pari Passu Whole Loan; and (d) until the
sale is completed, and a reasonable period of time (but no less time than is afforded to other offerors, the Directing Holder
and the Risk Retention Consultation Party) prior to the proposed sale date, all information and other documents being provided
to other offerors and all leases or other documents that are approved by the Master Servicer or the Special Servicer in connection
with the proposed sale. The holder of the related Serviced Pari Passu Companion Loan (or its representative) will be permitted
to submit an offer at any sale of such Whole Loan; however, the related Mortgagor and its agents and Affiliates shall not
be permitted to submit an offer at such sale. Notwithstanding the foregoing, with respect to each Serviced Whole Loan, the holder
of the related Companion Loan may waive any of the delivery or timing requirements set forth in this paragraph with respect to
the related Whole Loan. If the Trustee is required to determine whether a cash offer by an Interested Person constitutes a fair
price, the Trustee may (at its option and at the expense of the offering Interested Person purchaser) designate an independent
third party expert in real estate or commercial mortgage loan matters with at least five (5) years’ experience in valuing
or investing in loans similar to the subject Mortgage Loan, that has been selected with reasonable care by the Trustee to determine
if such cash offer constitutes a fair price for such Mortgage Loan. The Trustee shall act in a commercially reasonable manner
in making such determination. If the Trustee designates such a third party to make such determination, the Trustee may rely conclusively
upon such third party’s determination. The reasonable fees of, and the costs of all Appraisals, inspection reports and broker
opinions of


 






    -244-


     


    

 


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 Subordinate Companion Loan(s) for each applicable Serviced 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 Subordinate
Companion Loan(s) 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 Subordinate Companion Loan, repurchased by the applicable Mortgage Loan Seller or otherwise ceases to be subject to this
Agreement, the related Subordinate Companion Loan(s) will no longer be subject to this Agreement. In addition, with respect to
any Serviced AB Whole Loan, pursuant to the terms of the related Intercreditor Agreement and this Agreement, if the related Serviced
AB 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 is not required to sell the related
Subordinate Companion Loan(s) together with such Mortgage Loan as one whole loan. If no Control Appraisal Period exists, the Special
Servicer may not sell the Subordinate Companion Loan(s) without the prior consent of the holder of the Subordinate Companion Loan(s). 
If a Control Appraisal Period is continuing, the Special Servicer has the right (but not the obligation) to sell the Subordinate
Companion Loan(s) without the consent of the holder of the Subordinate Companion Loan(s).


 


(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)            
If 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


 






    -245-


     


    

 





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


 






    -246-


     


    

 


The
foregoing shall not, however, be construed to limit any liability that may otherwise be imposed on such Person for any failure
by such Person to comply with the conditions to making such an election under Section 3.17 or to comply with the terms
of Section 3.17 and the other provisions of this Agreement that apply once such an election, if any, has been made;
provided, however, that the fact that a decision to recover such Nonrecoverable Advances over time, or not to do
so, benefits some Classes of Certificateholders to the detriment of other Classes shall not, with respect to the Master Servicer
or the Special Servicer, as applicable, constitute a violation of the Servicing Standard and/or with respect to the Trustee (solely
in its capacity as Trustee), constitute a violation of any fiduciary duty to Certificateholders or any contractual obligation
hereunder. If the Master Servicer or the Trustee, as applicable, determines, in its sole discretion, that its ability to fully
recover the Nonrecoverable Advances has been compromised, then the Master Servicer or the Trustee, as applicable, shall be entitled
to immediate reimbursement of Nonrecoverable Advances with interest thereon at the Reimbursement Rate from all amounts in the
Collection Account for such Distribution Date (deemed first from principal and then interest). Any such election
by any such party to refrain from reimbursing itself or obtaining reimbursement for any Nonrecoverable Advance or portion thereof
with respect to any one or more collection periods shall not limit the accrual of interest at the Reimbursement Rate on such Nonrecoverable
Advance for the period prior to the actual reimbursement of such Nonrecoverable Advance. The Master Servicer’s or the Trustee’s,
as applicable, agreement to defer reimbursement of such Nonrecoverable Advances as set forth above is an accommodation to the
Certificateholders and shall not be construed as an obligation on the part of the Master Servicer or the Trustee, as applicable,
or a right of the Certificateholders. Nothing herein shall be deemed to create in the Certificateholders a right to prior payment
of distributions over the Master Servicer’s or the Trustee’s, as applicable, right to reimbursement for Advances (deferred
or otherwise) and accrued interest thereon. In all events, the decision to defer reimbursement or to seek immediate reimbursement
of Nonrecoverable Advances shall be deemed to be in accordance with the Servicing Standard and none of the Master Servicer, the
Trustee or the other parties to this Agreement will have any liability to one another or to any of the Certificateholders or any
of the Companion Holders for any such election that such party makes as contemplated by Section 3.17 or for any losses,
damages or other adverse economic or other effects that may arise from such an election.


 


The
aggregate of any Excess Prepayment Interest Shortfall with respect to the Mortgage Loans for any Distribution Date will be allocated
on such Distribution Date among each class of Certificates, pro rata, in accordance with their respective Interest Accrual
Amounts for that Distribution Date.


 


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

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


 


Section 3.18      
Modifications, Waivers, Amendments and Consents. (a)  Except as set forth in Section 3.08(a), Section 3.08(b),
this Section 3.18(a), Section 3.18(d), Section 3.18(h), Section 3.18(i) and Section 6.08,
but subject to any other conditions set forth thereunder (including, without limitation, the Special Servicer’s processing
and/or consent rights pursuant to this subsection (a) with respect to any modification, waiver or amendment that constitutes
a Special Servicer Decision or a Major Decision) and, with respect to any Mortgage Loan (other than any Non-Serviced Mortgage
Loan) or any Serviced Whole Loan, (and with respect to any Serviced Whole Loan, subject to the rights of the related Companion
Holder to advise or consult with the Master Servicer or the Special Servicer, as applicable, with respect to, or to consent to,
a modification, waiver or amendment, in each case, pursuant to the terms of the related Intercreditor Agreement), the Master Servicer
shall not provide any consent or make any decision, including agreeing to any modification, waiver or amendment to the terms of
a Mortgage Loan and/or Companion Loan unless such consent or decision constitutes a Master Servicer Decision, unless, with respect
to a Major Decision or Special Servicer Decision, the Master Servicer and the Special Servicer mutually agree with respect to
a Non-Specially Serviced Loan that the Master Servicer shall process such request but in all events subject to the prior written
consent or deemed consent of the Special Servicer, which consent shall be deemed given if the Special Servicer does not respond
within ten (10) days of delivery to the Special Servicer of the Master Servicer’s written recommendations and analysis,
and all information that is in the Master Servicer’s possession reasonably requested by the Special Servicer in order to
grant or withhold such consent, plus the time period provided to any Serviced Companion Loan Holder under the related Intercreditor
Agreement to consent to such Major Decision). Subject to Section 6.08, the Special Servicer may waive, modify or amend
(or consent to waive, modify or amend) any provision of a Mortgage Loan or Serviced Companion Loan that is not in default or as
to which default is not reasonably foreseeable; provided that no extension entered into pursuant to this Section 3.18(a)
shall extend the Maturity Date beyond the earlier of (i) five (5) years prior to the Rated Final Distribution Date and
(ii) in the case of a Mortgage Loan secured solely or primarily by a leasehold estate and not also the related fee interest,
the date twenty (20) years or, to the extent consistent with the Servicing Standard giving due consideration to the remaining
term of the Ground Lease, ten (10) years, prior to the expiration of such leasehold estate. If such extension would extend the
Maturity Date of such Mortgage Loan and/or related Companion Loan for more than twelve (12) months from and after the original
Maturity Date of such Mortgage Loan and/or related Companion Loan and such Mortgage Loan and/or related Companion Loan is not
in default or default with respect thereto is not reasonably foreseeable, prior to any such extension, (1) the Master Servicer
or the Special Servicer (whichever is processing such action) shall provide the Trustee, the Certificate Administrator, the Special
Servicer or the Master Servicer (as applicable), the Operating Advisor, the Directing Holder and the Risk Retention Consultation
Party (in the case of the Directing Holder, only if no Consultation Termination Event is continuing and in the case of the Directing
Holder or the Risk Retention Consultation Party, other than with respect to an Excluded Loan as to such party), 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


 






    -248-


     


    

 


Mortgagor, to be paid as an expense of the Trust in accordance with Section 3.18(d))
that such extension would not constitute a “significant modification” of the Mortgage Loan and/or Serviced Companion
Loan within the meaning of Treasury Regulations Section 1.860G-2(b) and (2) subject to the Servicing Standard, the Special
Servicer shall (A) obtain the consent of the Directing Holder pursuant to Section 6.08(a) ((i) if no Control Termination
Event is continuing and (ii) other than with respect to a Mortgage Loan that is an Excluded Loan as to such party), (B) consult
with the Directing Holder and, with respect to Specially Serviced Loans, the Risk Retention Consultation Party pursuant to Section 6.08(a)
((i) with respect to the Directing Holder, only during a Control Termination Event while no Consultation Termination Event
is continuing and (ii) in each case, other than with respect to any Excluded Loan as to such party) and (C) if a Consultation
Termination Event is continuing and other than with respect to an Excluded Loan as to such party, consult with the Risk Retention
Consultation Party pursuant to Section 6.08(a) (which consent or consultation shall be coordinated through the Special
Servicer). Notwithstanding the foregoing, subject to the rights of the related Companion Holder to advise the Master Servicer
with respect to, or consent to, such modification, waiver or amendment pursuant to the terms of the related Intercreditor Agreement,
and subject to the Special Servicer’s processing and/or consent rights pursuant to this subsection (a), the Master
Servicer, with respect to Non-Specially Serviced Loans, without the consent of or consultation with the Special Servicer, the
Operating Advisor or the Directing Holder, may modify or amend the terms of any Mortgage Loan and/or related Serviced Companion
Loan in order to (i) cure any ambiguity or mistake therein 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).


 


Neither
the Master Servicer nor the Special Servicer shall enter into, or structure (including, without limitation, by way of the application
of credits, discounts, forgiveness or otherwise), any modification, waiver, amendment, work-out, consent or approval with respect
to any Mortgage Loan or Serviced Whole Loan in a manner that would be inconsistent with the allocation and payment priorities
described under Section 3.02(b) of this Agreement or in the related Intercreditor Agreement (if any).


 


Subject
to Section 6.08, applicable law and the Mortgage Loan and/or related Serviced Companion Loan documents, neither the
Master Servicer nor the Special Servicer shall permit the substitution of any Mortgaged Property (or any portion thereof) for
one or more other parcels of real property at any time the Mortgage Loan and/or related Serviced Companion Loan is not in default
pursuant to the terms of the related Mortgage Loan and/or related Serviced Companion Loan documents or default with respect thereto
is not reasonably foreseeable unless (i) the Master Servicer or the Special Servicer, as applicable, obtains Rating Agency
Confirmation from each Rating Agency (and delivers such Rating Agency Confirmation to the Directing Holder and the Risk Retention
Consultation Party, if permitted by the applicable Rating Agency) and Companion Loan Rating Agency Confirmations with respect
to any Serviced Companion Loan Securities 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


 






    -249-


     


    

 


Special Servicer, as applicable, may obtain and rely
upon an Opinion of Counsel (at the expense of the related Mortgagor if not prohibited by the terms of the related Mortgage Loan
documents, and if so prohibited, at the expense of the Trust) with respect thereto).


 


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


 


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


 


Subject
to Section 6.08, if a Mortgagor satisfies the requirements set forth in the definition of “COVID Modification”,
the Special Servicer may enter into a COVID Modification with the related Mortgagor. In exchange for a fee as described below,
the Special Servicer shall be responsible for processing any COVID Modification and any related COVID Modification Agreement for
any COVID Modified Loan.


 


Mortgagors
may request payment forbearance because of COVID-19 related financial hardship. The Special Servicer shall be allowed to grant
a forbearance on a Mortgage Loan related to the global COVID-19 emergency only if (i) prior to the 2021 calendar year, the period
of forbearance granted, when added to any prior periods of forbearance granted before or after the Trust acquired such Mortgage
Loan (whether or not such prior grants of forbearance were specifically covered by Revenue Procedure 2020-26), does not exceed
six months (or such longer period of time as may be allowed by future guidance that is binding on federal income tax authorities)
and such forbearance is specifically covered by Revenue Procedure 2020-26, (ii) such forbearance is permitted under another provision
of this Agreement (including forbearances due to default or reasonably foreseeable default) and the requirements under such provision
are satisfied, or (iii) an Opinion of Counsel is delivered to the effect that such forbearance will not result in an Adverse REMIC
Event.


 


Any
fees or other charges charged by the Special Servicer in connection with processing any COVID Modification or related COVID Modification
Agreement with respect to any COVID Modified Loan (in the aggregate with any other COVID Modification or COVID Modification Agreement
with respect to such COVID Modified Loan) (such fee, a “COVID Modification Fee”) shall not exceed an amount
equal to $30,000 (plus reasonable and customary


 






    -250-


     


    

 


attorney’s fees and expenses, out of pocket third party fees and expenses
and filing fees) and shall only be borne by the related Mortgagor, not the Trust.


 


Notwithstanding
the foregoing, the Master Servicer and the Special Servicer may mutually agree that the Master Servicer will process any of the
foregoing matters that are Major Decisions (other than a COVID Modification) or Special Servicer Decisions with respect to any
Performing Loan. If the Master Servicer and the Special Servicer mutually agree that the Master Servicer will process any Major
Decision or Special Servicer Decision with respect to a Non-Specially Serviced Loan, the Master Servicer shall obtain the consent
(or deemed consent) of the Special Servicer as provided in Section 3.18(b).


 


(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 (or any Non-Specially Serviced Loan with respect to which such determination
derives from the Special Servicer’s consideration of a Major Decision or Special Servicer Decision that is subject to its
processing and/or consent rights pursuant to Section 3.18(a)) 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 recovery on
a net present value basis (the relevant discounting to be performed at the related Mortgage Rate) to the Trust and, if applicable,
the related Companion Holders, as the holders of the related Serviced Companion Loan, than liquidation of such Specially Serviced
Loan, then the Special Servicer may agree to a modification, waiver or amendment of such Specially Serviced Loan, subject to (x) the
provisions of this Section 3.18(b) and Section 3.18(c), (y) with respect to any Major Decision, (a)
with the approval of the Directing Holder (if no Control Termination Event is continuing) or upon consultation with the Directing
Holder (in each case, other than with respect to an Excluded Loan as to such party) as provided in Section 6.08 and
(b) upon consultation with the Risk Retention Consultation Party (other than with respect to an Excluded Loan as to such party)
as provided in Section 6.08; provided that, with respect to any Serviced AB Whole Loan, the Special Servicer
shall not consult with the Risk Retention Consultation Party unless the Directing Certificateholder is the applicable Directing
Holder; and (z) additionally, with respect to a Serviced Whole Loan, the rights of the related Serviced Companion Noteholder,
to advise or consult with the Special Servicer with respect to, or consent to, such modification, waiver or amendment, in each
case, pursuant to the terms of the related Intercreditor Agreement; provided that in the case of any release or substitution
of collateral (other than a defeasance), the Special Servicer shall obtain 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
(regardless of whether an Operating Advisor Consultation Event is continuing), the Special Servicer shall consult with the Operating
Advisor (telephonically or electronically), on a non-binding basis, in connection with the related transactions involving proposed
Major Decisions that it is processing or for which its consent is required and consider alternative actions recommended by the
Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting
with the Operating Advisor.

The
Master Servicer, prior to taking any action with respect to any Major Decision or any Special Servicer Decision, shall refer the
request to the Special Servicer. The Special Servicer shall process the request directly (other than any Major Decision described
in subclauses (i) and (ii) of clause (xiii) of the definition of “Major Decision” with respect
to a Non-Specially Serviced Loan, which shall be processed by the Master Servicer subject to the consent rights of the Special
Servicer). However, if the Master Servicer and Special Servicer mutually agree that the Master Servicer shall process such request,
the Master Servicer shall prepare and submit its written analysis and recommendation to the Special Servicer with all information
that is in the Master Servicer’s possession that the Special Servicer may reasonably request in order to withhold or grant
its consent, and in all cases the Special Servicer may approve or disapprove any modification, waiver or amendment that constitutes
such a Major Decision or a Special Servicer Decision.


 


The
Special Servicer shall use its reasonable efforts to the extent reasonably possible to cause each Specially Serviced Loan to fully
amortize prior to the Rated Final Distribution Date and shall not agree to a modification, waiver or amendment of any term of
any Specially Serviced Loan if such modification, waiver or amendment would (1) extend the Maturity Date of any such Specially
Serviced Loan to a date occurring later than the earlier of (a) five years 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 (i) if no Control Termination Event is continuing, with the consent of the Directing Certificateholder
and (ii) 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 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 Loans generally at the related Mortgage Rate.


 


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


 


(d)           
To the extent consistent with this Agreement, the Master Servicer (subject to the Special Servicer’s consent rights pursuant
to Section 3.18(a) if any such waiver, modification or amendment constitutes a Major Decision or Special Servicer
Decision) or the Special Servicer may, consistent with the Servicing Standard, agree to any waiver, modification or amendment
of a Mortgage Loan and/or Serviced Companion Loan that is not in default or as to which default is not reasonably foreseeable
only if the contemplated waiver, modification or amendment (i) will not be a “significant modification” of the
Mortgage Loan within the meaning


 






    -252-


     


    

 


of Treasury Regulations Section 1.860G-2(b) and (ii) will not cause an Adverse REMIC Event
to occur. In making this determination, the Master Servicer or Special Servicer may obtain and rely upon (and shall provide to
the Trustee and the Certificate Administrator if obtained) an Opinion of Counsel (at the expense of the related Mortgagor or such
other Person requesting such modification or, if such expense cannot be collected from the related Mortgagor or such other Person,
to be paid out of the Collection Account pursuant to Section 3.05(a); provided that the Master Servicer or
the Special Servicer, as the case may be, shall use its reasonable efforts to collect such fee from the Mortgagor or such other
Person to the extent permitted under the related Mortgage Loan documents). Notwithstanding the foregoing, neither the Master Servicer
nor the Special Servicer may waive the payment of any Yield Maintenance Charge or the requirement that any prepayment of a Mortgage
Loan 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 (during
an Operating Advisor Consultation Event), the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing
Holder, other than during a Consultation Termination Event, and in the case of the Directing Holder or the Risk Retention Consultation
Party, other than with respect to an Excluded Loan as to such party), the applicable Companion Holder, the related Mortgage
Loan Seller (if such Mortgage Loan Seller is not a Master Servicer or Sub-Servicer of such Mortgage Loan, the Directing Holder
or the Risk Retention Consultation Party) and the 17g-5 Information Provider (which shall promptly post such notice on the 17g-5
Information Provider’s Website in accordance with Section 3.13(c)), and the Master Servicer shall notify the
Certificate Administrator, the Trustee, the Special Servicer, the Directing Holder, the Risk Retention Consultation Party (other
than with respect to an Excluded Loan as to such party and if no Consultation Termination Event is continuing), the related Mortgage
Loan Seller (so long as such Mortgage Loan Seller is not the Master Servicer or Sub-Servicer of such Mortgage Loan or the Directing
Holder or Risk Retention Consultation Party), any related Companion Holder 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. The Custodian shall make available copies of each agreement whereby the modification,
waiver or amendment of any term of any Mortgage Loan is effected available for review during normal business hours at the office
of the Custodian. Following receipt of the Master Servicer’s or the Special Servicer’s, as applicable, delivery of
the aforesaid modification, waiver or amendment to the Certificate Administrator, the Certificate Administrator shall forward
a copy thereof to each Holder of a Certificate (other than the Class Z or Class R Certificates) upon request. With respect
to the processing of any modification, waiver or consent related to any Mortgagor incurring Additional Debt or mezzanine debt,
the Special Servicer (if the Special Servicer processes such modification, waiver or consent pursuant to Section 3.18(a))
or the Master Servicer (if the Master Servicer processes such modification, waiver or consent pursuant to Section 3.18(a))
shall, on or before the later of (i) 3:00 p.m. on the related P&I Advance Date and (ii) five (5) Business Days
immediately following the Master Servicer or the Special Servicer, as applicable, obtaining actual knowledge of the incurrence
of such Additional Debt or mezzanine debt, deliver notice of the Mortgagor’s incurrence of such debt, substantially in the
form of Exhibit KK, to cts.sec.notifications@wellsfargo.com and an Additional Disclosure Notification in the form
of Exhibit EE. The notice contemplated in the preceding sentence shall set forth, to the extent the Special Servicer or
Master Servicer, as applicable, 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. If either (i) the CREFC® Investor Reporting Package is amended to include such information set forth
above, in a manner reasonably acceptable to the Master Servicer, the Special Servicer and Certificate Administrator, as applicable,
and the Master Servicer confirms with the Certificate Administrator that such amended CREFC® Investor Reporting
Package enables the Certificate Administrator to include such information on Form 10-D in a manner reasonably acceptable to the
Certificate Administrator, or (ii) the Trust is no longer subject to the Exchange Act, the additional report in the form
of Exhibit KK shall no longer be required hereunder. From time to time, the Master Servicer, the Special Servicer
and Certificate Administrator may agree on a different delivery time and format for the information set forth in this paragraph.


 


(h)            
The Master Servicer shall process all defeasance transactions, subject to the Special Servicer’s consent with respect to
any Major Decision relating to a defeasance. 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


 






    -254-


     


    

 


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 Companion Loan Rating Agency Confirmations with
respect to any Serviced Companion Loan Securities; 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 for any Mortgage Loan that (together with any other Crossed Underlying Loans in a Crossed
Mortgage Loan Group with such Mortgage Loan) is: (i) a Mortgage Loan with a Cut-off Date Balance less than $35,000,000, (ii) a
Mortgage Loan that represents less than 5% of the aggregate Cut-off Date Balance of all Mortgage Loans and (iii) a Mortgage
Loan that is not one of the ten largest Mortgage Loans by Stated Principal Balance. Notwithstanding the foregoing, if 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 (subject to the Special
Servicer’s processing and/or consent rights pursuant to Section 3.18(a) with respect to any such action that
constitutes a Major Decision or Special Servicer Decision) reasonably determines that allowing their use would not cause a default
or event of default to become reasonably foreseeable and the Master Servicer receives an Opinion of Counsel (at the expense of
the Mortgagor to the extent permitted under the Mortgage Loan documents and, if applicable, Companion Loan documents or otherwise
as a Trust Fund expense) to the effect that such use would not be and would not constitute a “significant modification”
of such Mortgage Loan or Companion Loan pursuant to Treasury Regulations Section 1.860G-2(b) and would not otherwise constitute
an Adverse REMIC Event with respect

to any Trust REMIC; and provided, further, that the requirements set forth in
Section 3.18(h) (including receipt of any Rating Agency Confirmation) are satisfied; and provided, further,
that such securities are backed by the full faith and credit of the United States government, or the Master Servicer shall obtain
Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency Confirmations with respect to any Serviced
Companion Loan Securities. Notwithstanding the foregoing, with respect to certain Mortgage Loans that are subject to defeasance
and identified on Schedule 3, the related Mortgage Loan Seller (or the originator of the related Mortgage Loan) has transferred
to a third party or has retained on behalf of itself or its Affiliate the right to establish or designate the successor borrower
and/or to purchase or cause to be purchased the related defeasance collateral (collectively, the “Loan Seller Defeasance
Rights and Obligations”). If the Master Servicer receives notice of a defeasance request with respect to a Mortgage
Loan that provides for Loan Seller Defeasance Rights and Obligations in the related Mortgage Loan documents, the Master Servicer
shall provide, within five (5) Business Days of receipt of such notice, written notice of such defeasance request to the related
Mortgage Loan Seller (and/or any other party identified in the related Mortgage Loan Purchase Agreement). Until such time as the
related Mortgage Loan Seller provides written notice to the contrary, notice of a defeasance of a Mortgage Loan with Loan Seller
Defeasance Rights and Obligations shall be delivered to the related Mortgage Loan Seller pursuant to the notice provisions hereof.
If the successor borrower is not designated or formed by the related Mortgage Loan Seller 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 maintained in the Collection Account for a period in excess of 365 days
(or 366 days in the case of a leap year).


 


(k)            
Notwithstanding anything to the contrary in this Agreement, neither the Master Servicer nor the Special Servicer, as applicable,
shall, unless it has received Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency Confirmations
with respect to any Serviced Companion Loan Securities (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


 






    -256-


     


    

 


of the related property manager or the designation of any replacement property manager,
with respect to any Mortgaged Property that secures a Mortgage Loan that (i) is one of the ten largest Mortgage Loans by
Stated Principal Balance or (ii) has an unpaid principal balance that is at least equal to five percent (5%) of the then
aggregate principal balance of all Mortgage Loans or $35,000,000.


 


(l)             
Notwithstanding anything to the contrary in this Agreement, in connection with any modification, waiver, consent or amendment
in connection with any defeasance transaction contemplated in subclause (ii) of clause (xiii) of the definition
of “Major Decision”, the Master 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.


 


Section 3.19      
 Transfer of Servicing Between Master Servicer and Special Servicer; Recordkeeping; Asset Status Report. (a)  Upon
determining that a Servicing Transfer Event has occurred with respect to any Mortgage Loan (other than any Non-Serviced Mortgage
Loan) or Serviced Companion Loan, the Master Servicer or the Special Servicer, as applicable, shall promptly give notice to the
Master Servicer or the Special Servicer, as applicable, the Operating Advisor and the Directing Holder (in the case of the Directing
Holder, (i) if no Consultation Termination Event is continuing and (ii) other than with respect to an Excluded Loan as to such
party) thereof, and the Master Servicer shall deliver the related Mortgage File and Servicing File to the Special Servicer and
concurrently provide a copy of such Servicing File, exclusive of all Privileged Communications, to the Operating Advisor. The
Master Servicer shall use its reasonable efforts to provide the Special Servicer with all information, documents and records (including
records stored electronically on computer tapes, magnetic discs and the like) relating to such Mortgage Loan and, if applicable,
the related Serviced Companion Loan, either in the Master Servicer’s possession or otherwise available to the Master Servicer
without undue burden or expense, and reasonably requested by the Special Servicer to enable it to assume its functions hereunder
with respect thereto. The Master Servicer shall use its reasonable efforts to comply with the preceding sentence within five (5)
Business Days of the occurrence of each related Servicing Transfer Event (or, in the case of clauses (b) or (d)
of the definition of Servicing Transfer Event, within five (5) Business Days of receiving notice from the Special Servicer
of such Servicing Transfer Event when the Special Servicer makes the determination) and in any event shall continue to act as
Master Servicer and administrator of such Mortgage Loan and, if applicable, the related Serviced Companion Loan until the Special
Servicer has commenced the servicing of such Mortgage Loan and, if applicable, the related Serviced Companion Loan. The Master
Servicer shall deliver to the Trustee, the Certificate Administrator, the Operating Advisor, the Directing Holder (other than
with respect to any Excluded Loan as to such party and only if no Consultation Termination Event is continuing), 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. If no Consultation Termination Event is continuing, 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.


 






    -257-


     


    

 


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


 


(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 (i) sixty (60) days after a Servicing Transfer Event for a Mortgage Loan (other than a Non-Serviced Mortgage Loan)
and, if applicable, any related Companion Loan (if any Serviced Whole Loan becomes a Specially Serviced Loan) and (ii) prior to
taking action with respect to any Major Decision (or making a determination not to take action with respect to a Major Decision)
with respect to a Specially Serviced Loan, the Special Servicer shall deliver in electronic format a report (the “Asset
Status Report”) with respect to such Mortgage Loan and related Companion Loan and the related Mortgaged Property (the
“Initial Delivery Date”) and will be required to prepare one or more additional Asset Status Reports with respect
to any such Specially Serviced Loan subsequent to the issuance of a Final Asset Status Report to the extent that during the course
of the resolution of such Specially Serviced Loan material changes in the strategy reflected in the initial Final Asset Status
Report (or subsequent Final Asset Status Report) are necessary to reflect the then current recommendation as to how the Specially
Serviced Loan might be returned to performing status or otherwise liquidated in accordance with the Servicing Standard (each such
report a “Subsequent Asset Status Report”). Each Asset Status Report shall be delivered in electronic form
to the Master Servicer, the Directing Holder (but other than in respect of an Excluded Loan as to such party and while no Consultation
Termination Event exists), the Risk Retention Consultation Party (but only with respect to any Excluded Loan as to


 






    -258-


     


    

 


such party),
the Operating Advisor (but, (i) other than with respect to an Excluded Loan as to the Directing Holder, only during an Operating
Advisor Consultation Event and (ii) with respect to a Serviced AB Whole Loan only to the extent it is also subject to a Control
Appraisal Period under the related Intercreditor Agreement), and the 17g-5 Information Provider (which shall promptly post such
report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)) and, with respect to
any related Serviced Companion Loan, to the extent the related Serviced Companion Loan has been included in an Other Securitization,
to the master servicer of such Other Securitization into which the related Serviced Companion Loan has been sold or to the related
Companion Holder. The Special Servicer shall notify the Operating Advisor of whether any Asset Status Report delivered to the
Operating Advisor is a Final Asset Status Report. Such Asset Status Report shall set forth the following information to the extent
reasonably determinable based on the information that was delivered to the Special Servicer in connection with the transfer of
servicing pursuant to the Servicing Transfer Event:


 


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


 


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


 


(iii)              
the most current rent roll 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 foreclosed or otherwise realized upon (including any proposed sale of a Defaulted Loan or REO Property),
(B) a description of any such proposed or taken actions, and (C) the alternative courses of action that were or are being considered
by the Special Servicer in connection with the proposed or taken actions;


 


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


 


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


 


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


 






    -259-


     


    

 


(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.


 


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


 


If
within ten (10) days (or, in the case of an Asset Status Report prepared prior to making a determination of an Acceptable Insurance
Default, twenty (20) days) of receiving an Asset Status Report (other than with respect to an Excluded Loan as to such party and
only if no Control Termination Event is continuing), the Directing Holder does not disapprove such Asset Status Report in writing
(or, in the case of an Asset Status Report prepared prior to making a determination of an Acceptable Insurance Default, twenty
(20) days), or if the Special Servicer makes a determination, in accordance with the Servicing Standard that the disapproval by
the Directing Holder (communicated to the Special Servicer within ten (10) days) is not in the best interest of all the Certificateholders),
the Special Servicer shall implement the recommended action as outlined in such Asset Status Report; provided, however,
that the Special Servicer may not take any action that is contrary to applicable law, the Servicing Standard or the terms of the
applicable Mortgage Loan documents. If, with respect to any Mortgage Loan other than an Excluded Loan as to such party and if
no Control Termination Event is continuing, the Directing Holder disapproves such Asset Status Report within ten (10) days (or,
in the case of an Asset Status Report prepared prior to making a determination of an Acceptable Insurance Default, twenty (20)
days) of receipt and the Special Servicer has not made the affirmative determination described above, the Special Servicer shall
revise such Asset Status Report and deliver a new Asset Status Report as soon as practicable, but in no event later than thirty
(30) days after such disapproval, to the Master Servicer, the Directing Holder (if no Consultation Termination Event is continuing
and other than if an Excluded Loan as to such party is involved), the Operating Advisor (but only during an Operating Advisor
Consultation Event) and the 17g-5 Information Provider (which shall promptly post such report on the 17g-5 Information Provider’s
Website in accordance with Section 3.13(c)) and, in the case of a Serviced Whole Loan, the related Serviced Companion
Noteholder; provided, however, that, if the Special Servicer determines that emergency action is necessary to protect
the related Mortgaged Property or the interests of the Certificateholders and any related Serviced Companion Noteholder, or if
a failure to take any such action at such time would be inconsistent with the Servicing Standard, the Special Servicer may take
actions with respect to the related Mortgaged Property before the expiration of the ten (10) day period (or, in the case of an
Asset Status Report prepared prior to making a determination of an Acceptable Insurance Default, twenty (20) day period) if the
Special Servicer reasonably determines in accordance with the Servicing Standard that failure to take such actions before the
expiration of


 






    -260-


     


    

 


the ten (10) day period (or, in the case of an Asset Status Report prepared prior to making a determination of an
Acceptable Insurance Default, twenty (20) day period) would materially and adversely affect the interest of the Certificateholders
and the related Serviced Companion Noteholder (if applicable) and the Special Servicer has made a reasonable effort, if no Control
Termination Event is continuing and other than if an Excluded Loan is involved, to contact the Directing Certificateholder. With
respect to any Mortgage Loan other than an Excluded Loan with respect to the Directing Holder or the Holder of the majority of
the Controlling Class, if no Control Termination Event is continuing, the Special Servicer shall revise such Asset Status Report
as described above in this Section 3.19(d) until the Directing Holder shall fail to disapprove such revised Asset
Status Report in writing within ten (10) days or, in the case of an Asset Status Report prepared prior to making a determination
of an Acceptable Insurance Default, twenty (20) days) of receiving such revised Asset Status Report or until the Special Servicer
makes a determination, in accordance with the Servicing Standard, that the disapproval is not in the best interests of the Certificateholders;
provided that, if the Directing Holder has not approved the Asset Status Report for a period of sixty (60) Business Days
following the first submission of an Asset Status Report, the Special Servicer may act upon the most recently submitted form of
Asset Status Report, if consistent with the Servicing Standard; provided, however, that such Asset Status Report
does not, and is not intended to be, a substitute for the approvals that are specifically required pursuant to Section 6.08.
The procedures described in this paragraph are collectively referred to as the “Directing Holder Approval Process”.
The Special Servicer may, from time to time, modify any Asset Status Report it has previously delivered and implement such report;
provided that such report has 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 (other than a Non-Serviced Mortgage Loan) with
respect to the Directing Holder or the Holder of the majority of the Controlling Class (regardless of whether an Operating
Advisor Consultation Event has occurred and is continuing), the Special Servicer shall consult with the Operating Advisor (telephonically
or electronically), on a non-binding basis, in connection with an Asset Status Report for an Excluded Loan with respect to the
Directing Holder or the Holder of the majority of the Controlling Class that includes a Major Decision that it is processing or
for which its consent is required and consider alternative actions recommended by the Operating Advisor, in respect thereof, in
accordance with the procedures set forth in Section 6.08 for consulting with the Operating Advisor.


 


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


 






    -261-


     


    

 


Prior
to an Operating Advisor Consultation Event, the Special Servicer shall deliver each Final Asset Status Report to the Operating
Advisor after the completion of the Directing Holder Approval Process. The Operating Advisor’s review of any such Final
Asset Status Report shall only provide background information to support the Operating Advisor’s duties concerning the Special
Servicer’s compliance with the Servicing Standard, and the Operating Advisor shall not provide comments to the Special Servicer
in respect of such Final Asset Status Report.


 


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


 


During
a Control Termination Event (and at any time with respect to any Excluded Loan with respect to such party or the Holder of the
majority of the Controlling Class), the Directing Holder will have no right to consent to any Asset Status Report under this Section 3.19.
During a Control Termination Event but while no Consultation Termination Event is continuing, the Special Servicer shall send
the Directing Holder (except with respect to any Excluded Loan as to such party), and, during an Operating Advisor Consultation
Event, the Operating Advisor, the Asset Status Report and the Operating Advisor and the Directing Holder shall consult with the
Special Servicer (telephonically or electronically) and propose alternative courses of action and provide other feedback in respect
of any Asset Status Report. The Directing Holder (or, if the Directing Holder is the Directing Certificateholder, other than in
its capacity as a Certificateholder) (in each case, during a Consultation Termination Event (and at any time with respect to any
Excluded Loan as to such party)), will 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
on a non-binding basis with respect


 






    -262-


     


    

 


to any Asset Status Report as described above. The Special Servicer may choose to revise the
Asset Status Report as it deems reasonably necessary in accordance with the Servicing Standard to take into account any input
and/or recommendations of the Operating Advisor or the Directing Holder during the applicable periods described above, but is
under no obligation to follow any particular recommendation of the Operating Advisor or the Directing Holder.


 


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


 


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


 


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


 


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


 


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


 


(f)             
If no Control Termination Event is continuing, no later than two (2) Business Days following the establishment of a Final Asset
Status Report with respect to any Specially Serviced Loan (other than any Excluded Loan), the Special Servicer shall deliver in
electronic format to the Directing Certificateholder (other than with respect to any Excluded Loan as to such party) a draft notice
that will include a draft summary of the Final Asset Status Report


 






    -263-


     


    

 


(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 Whole
Loan if no Control Appraisal Period is continuing (to the extent approved by the related Directing Holder)). With respect to any
Mortgage Loan other than an Excluded Loan, if, while no Control Termination Event is continuing, within five (5) Business Days
of receipt of such draft summary, the Directing Certificateholder approves of, or does not disapprove of such draft summary, then
the Special Servicer shall deliver in electronic format such notice and summary of the Final Asset Status Report to the Certificate
Administrator for posting on the Certificate Administrator’s Website pursuant to Section 3.13(b). If the Directing
Certificateholder affirmatively disapproves of such summary in writing, then within two (2) Business Days of receipt of such disapproval,
the Special Servicer shall revise the summary and deliver such new summary to the Directing Certificateholder until the Directing
Certificateholder approves such draft summary; provided, however, that if the Directing Certificateholder has not
approved of the draft summary of the Final Asset Status Report within twenty (20) Business Days of receipt of the initial draft
summary of the Final Asset Status Report, then the most recent draft summary of the Final Asset Status Report delivered by the
Special Servicer prior to such 20th Business Day shall be deemed to be the final summary of the Final Asset Status Report; provided,
further, however, that if at any time the Special Servicer determines that any affirmative disapproval of such draft
summary by the Directing Certificateholder is not in the best interest of all the Certificateholders pursuant to the Servicing
Standard, the Special Servicer shall deliver in electronic format such notice and summary of the Final Asset Status Report to
the Certificate Administrator for posting on the Certificate Administrator’s Website pursuant to Section 3.13(b)
notwithstanding such disapproval. The Special Servicer shall promptly deliver (but in any event no later than two (2) Business
Days following its completion) a copy 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 a Subordinate
Companion Loan(s) is not subject to a Control Appraisal Period, which Final Asset Status Report has been approved or deemed approved
by the holder of the related Subordinate Companion Loan(s) 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, during a Control Termination Event, the Directing Holder
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 applicable, shall for any reason no longer act in such capacity hereunder (including, without limitation,
by reason of a Servicer Termination Event), the Trustee or its designee shall thereupon assume all of the rights and, except to
the extent they arose prior to the date of assumption, obligations of such party under such


 






    -264-


     


    

 


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 the Special Servicer, as applicable, any successor master servicer
or special servicer or any Certificateholder (or the related Companion Holder, if applicable) will 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; (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 applicable, is permitted hereunder to modify such Mortgage Loan; (vii) does not
permit the Sub-Servicer to take any action constituting a Major Decision or a Special Servicer Decision without the consent of
the Master Servicer or Special Servicer, as applicable (subject to the rights of the Directing Certificateholder pursuant to Section 6.08)
or any Mortgagor requested action that is neither a Major Decision nor a Special Servicer Decision without the Master Servicer’s
consent; (viii) with respect to any Sub-Servicing Agreement entered into after the Closing Date, if such Sub-Servicer is a Servicing
Function Participant or an Additional Servicer, such Sub-Servicer, at the time the related Sub-Servicing Agreement is entered
into, is not a Prohibited Party; and (ix) provides that the Sub-Servicer shall be in default under the related Sub-Servicing
Agreement and such Sub-Servicing Agreement shall be terminated (following the expiration of any applicable Grace Period) if the
Sub-Servicer fails (A) to deliver by the due date any Exchange Act reporting items required to be delivered to the Master
Servicer, Certificate Administrator or Depositor under Article XI or under the Sub-Servicing Agreement or to the master
servicer under any other pooling and servicing agreement that the Depositor is a party to, or (B) to perform in any material
respect any of its covenants or obligations contained in the Sub-Servicing Agreement regarding creating, obtaining or delivering
any Exchange Act reporting items required for any party to this Agreement to perform its obligations under Article XI
or under the Exchange Act reporting items required under any other pooling and servicing agreement that the Depositor is a
party to. Any successor master servicer or special servicer, as applicable, hereunder shall, upon becoming successor master servicer
or special servicer, as applicable, be assigned and may assume any Sub-Servicing Agreements from the predecessor Master Servicer
or the Special Servicer, as applicable (subject to Section 3.20(g)). 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


 






    -265-


     


    

 


Serviced Loans and continue to collect its Primary Servicing Fees
as if no Servicing Transfer Event had occurred and with respect to REO Properties (and the related REO Loans) as if no REO Acquisition
had occurred and to render such incidental services with respect to such Specially Serviced Loans and REO Properties as are specifically
provided for in such Sub-Servicing Agreement. The Master Servicer or the Special Servicer, as applicable, shall deliver to the
Trustee (i) copies of all Sub-Servicing Agreements entered into by it, in each case, promptly upon its execution and delivery
of such documents and (ii) upon request of the Trustee, any amendments or modifications to such Sub-Servicing Agreements.
References in this Agreement to actions taken or to be taken by the Master Servicer include actions taken or to be taken by a
Sub-Servicer on behalf of the Master Servicer; and, in connection therewith, all amounts advanced by any Sub-Servicer (if the
Sub-Servicing Agreement provides for Advances by the Sub-Servicer, although it need not so provide) to satisfy the obligations
of the Master Servicer hereunder to make Advances shall be deemed to have been advanced by the Master Servicer out of its own
funds and, accordingly, in such event, such Advances shall be recoverable by such Sub-Servicer in the same manner and out of the
same funds as if such Sub-Servicer were the Master Servicer, and, for so long as they are outstanding, such Advances shall accrue
interest in accordance with Section 3.03(d), such interest to be allocable between the Master Servicer and such Sub-Servicer
as may be provided (if at all) pursuant to the terms of the Sub-Servicing Agreement. For purposes of this Agreement, the Master
Servicer shall be deemed to have received any payment when a Sub-Servicer retained by it receives such payment. The Master Servicer
or the Special Servicer, as applicable, shall notify the Master Servicer or the Special Servicer, as applicable, the Trustee and
the Depositor (and the Special Servicer shall notify the Operating Advisor) in writing promptly of the appointment by it of any
Sub-Servicer, except that the Master Servicer need not provide such notice as to the Initial Sub-Servicing Agreements.


 


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


 


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


 


(d)           
If the Trustee or its designee becomes successor master servicer and assumes the rights and obligations of the Master Servicer
under any Sub-Servicing Agreement, the Master Servicer, at its expense, shall deliver to the assuming party all documents and
records relating to such Sub-Servicing Agreement and the Mortgage Loans and, if applicable, the


 






    -266-


     


    

 


Companion Loans then being serviced
thereunder and an accounting of amounts collected and held on behalf of it thereunder, and otherwise use reasonable efforts to
effect the orderly and efficient transfer of the Sub-Servicing Agreement to the assuming party.


 


(e)            
Notwithstanding the provisions of any Sub-Servicing Agreement and this Section 3.20, except to the extent provided
in Article XI with respect to the obligations of any Sub-Servicer that is an Initial Sub-Servicer, the Master Servicer
or the Special Servicer, as applicable, shall remain obligated and responsible to the Trustee, the Master Servicer (with respect
to the Special Servicer), the Special Servicer (with respect to the Master Servicer), holders of the Companion Loans serviced
hereunder and the Certificateholders for the performance of each party’s respective 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 or the Special Servicer, as applicable,
shall pay the fees of any Sub-Servicer engaged by such party 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 or the Special Servicer, as applicable, shall furnish to any Sub-Servicer
any documents necessary or appropriate to enable such Sub-Servicer to carry out its servicing and administrative duties under
any Sub-Servicing Agreement.


 


(g)            
Each Sub-Servicing Agreement shall provide that, if the Trustee or any other Person becomes successor master servicer, the Trustee
or such successor master servicer shall have the right to terminate such Sub-Servicing Agreement with or without cause and without
a fee. Notwithstanding the foregoing or any other contrary provision in this Agreement, the Trustee and any successor master servicer
shall assume (a) the Limited Subservicing Agreement, dated as of March 1, 2021, between Midland Loan Services, a Division
of PNC Bank, National Association, and 3650 REIT Loan Servicing LLC (the “Limited Subservicing Agreement”)
and (b) each Initial Sub-Servicing Agreement and (i) 3650 REIT Loan Servicing LLC’s rights and obligations under the
Limited Subservicing Agreement and 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
such Limited Subservicing Agreement or any such 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 Limited Subservicing Agreement and
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 that would increase the obligations or limit the rights of 3650 REIT Loan Servicing
LLC or the Initial Sub-Servicer, as applicable, hereunder and/or under the Limited Subservicing Agreement or the Initial Sub-Servicing
Agreement, as applicable, without the prior written consent of 3650 REIT Loan Servicing LLC or the Initial Sub-Servicer, as applicable
(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


 






    -267-


     


    

 


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, if no Control Termination Event
is continuing and other than with respect to any Mortgage Loan that is an Excluded Loan with respect to the Directing Holder,
the consent of the Directing Holder, except to the extent necessary for the Special Servicer to comply with applicable regulatory
requirements.


 


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


 


Section 3.21      
Interest Reserve Account. (a)  On the P&I Advance Date occurring in January (except during a leap year) and
February of each calendar year commencing in 2021 (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 immediately following
the Distribution Date occurring in the month preceding the month in which 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 pursuant to
this sentence in any particular January and/or February, “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 Holder and Operating Advisor Contact with the Master Servicer and the Special Servicer. Within a reasonable time
upon request from the Directing Holder or the Operating Advisor, as applicable, but no more often than on a monthly basis (or,
with respect to communications between the Directing Holder and the Master Servicer or the Special Servicer, as applicable, on
a more frequent basis that is commercially reasonable as mutually agreed to between the Directing Holder and the Master Servicer
or the Special Servicer, as applicable), 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 Holder ((i) if no Consultation
Termination Event is continuing and (ii) other than with respect to any Excluded Loan as to such party) and (b) the Operating
Advisor (with respect to the Special Servicer only), regarding the performance and servicing of the Mortgage Loans and/or REO
Properties for which the Master Servicer or the Special Servicer, as the case may be, is responsible.

Section 3.23      
Controlling Class Certificateholders, Directing Certificateholder and the Risk Retention Consultation Party; Certain Rights
and Powers of Directing Holder and the Risk Retention Consultation Party. (a)  Each Controlling Class Certificateholder
is hereby deemed to have agreed by virtue of its purchase of a Certificate to provide its name and address to the Certificate
Administrator and to notify the Master Servicer, the Certificate Administrator, the Special Servicer and the Operating Advisor
of the transfer of any Certificate of a Controlling Class by delivering a notice to each such Person substantially in the
form of Exhibit NN, 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. In any case, such notification may be delivered
via electronic mail.


 


On
the Closing Date, the initial Directing Certificateholder shall deliver to the parties to this Agreement a certification substantially
in the form of Exhibit P-1G to this Agreement. Upon the resignation or removal of the existing Directing Certificateholder,
any successor directing certificateholder shall execute and also 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 deliver to the parties to this Agreement 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 execute and also deliver to the parties to
this Agreement a certification substantially in the form of Exhibit P-1H to this Agreement prior to being recognized
as the new Risk Retention Consultation Party.


 


(b)           
Once a Directing Certificateholder has been selected, each of the Master Servicer, the Special Servicer, the Depositor, the Trustee,
the Certificate Administrator, the Operating Advisor and each other Certificateholder (or Certificate Owner, if applicable) shall
rely on such selection unless the Controlling Class Certificateholders entitled to appoint the Directing Certificateholder,
by Certificate Balance, or such Directing Certificateholder has notified the Master Servicer, the Special Servicer, the Trustee,
the Certificate Administrator, the Operating Advisor and each other Controlling Class Certificateholder, in writing, of the
resignation of such Directing Certificateholder or the selection of a new Directing Certificateholder. Upon the resignation of
a Directing Certificateholder, the Certificate Administrator shall request the Controlling Class Certificateholders to select
a new Directing Certificateholder. If (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








    -269-


     


    

 


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 may rely on the written notification
provided by the purported Controlling Class Certificateholder that owns the largest aggregate Certificate Balance of the
Controlling Class without independently verifying that such Controlling Class Certificateholder actually owns the largest
aggregate Certificate Balance of the Controlling Class. Additionally, once a Risk Retention Consultation Party has been selected,
each of the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor
and each other Certificateholder (or Certificate Owner, if applicable) may rely on such selection unless the Holders of the VRR
Interest entitled to appoint the Risk Retention Consultation Party, by Certificate Balance, or such Risk Retention Consultation
Party shall have notified the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Operating
Advisor and each other Holder of the VRR Interest, in writing, of the selection of a new Risk Retention Consultation Party.


 


(c)            
Until it receives notice to the contrary, each of the Master Servicer, the Special Servicer, the Certificate Administrator, the
Operating Advisor and the Trustee may 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)           
If no Directing Holder or Risk Retention Consultation Party has been appointed or identified to the Master Servicer or the Special
Servicer, as applicable, and the Master Servicer or the Special Servicer, as the case may be, has attempted to obtain such information
from the Certificate Administrator and no such entity has been identified to the Master Servicer or the Special Servicer, as applicable,
then until such time as the new Directing Holder or Risk Retention Consultation Party, as applicable, is identified, the Master
Servicer or the Special Servicer, as applicable, will have no duty to consult with, provide notice to, or seek the approval or
consent of any such Directing Holder 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, if no Consultation Termination Event is continuing, the Directing Certificateholder, a list of each Controlling
Class Certificateholder (or each Certificate Owner of the Controlling Class, if applicable), 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,
3650 Risk Retention Holder shall be the initial Directing Certificateholder and shall remain so until a successor is appointed
pursuant to the terms of this Agreement or until a Consultation Termination Event occurs and is continuing. As of the Closing
Date, there will be no Risk Retention Consultation Party.


 


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 rely on the preceding sentence with respect to the identity of the Directing Certificateholder
and the Risk Retention Consultation Party.


 






    -270-


     


    

 


(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 Holder may
have special relationships and interests that conflict with those of Holders of one or more Classes of Certificates; (ii) the
Directing Holder may act solely in the interests of the Holders of the Controlling Class; (iii) the Directing Certificateholder
does not have any liability or duties to the Holders of any Class of Certificates other than the Controlling Class; (iv) the
Directing Holder may take actions that favor interests of the Holders of one or more Classes of Certificates, including, without
limitation, the Controlling Class, over the interests of the Holders of one or more other Classes of Certificates; and (v) the
Directing Holder will have no liability whatsoever (other than to a Controlling Class Certificateholder, to the extent the
Directing Certificateholder is the Directing Holder) for having so acted, and no Certificateholder may take any action whatsoever
against the Directing Holder or any director, officer, employee, agent or principal of the Directing Holder for having so acted.


 


Each
Certificateholder acknowledges 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 VRR 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 VRR Interest; (iv) the Risk Retention Consultation Party may take actions that favor interests of the Holders of one
or more Classes including the VRR 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 an VRR 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)            
All requirements of the Master Servicer and the Special Servicer to provide notices, reports, statements or other information
(including the access to information on a website) to the Directing Holder contained in this Agreement shall also apply to each
Companion Holder with respect to information relating to the related Serviced Whole Loan, as applicable; provided, however,
that nothing in this subsection (h) shall in any way eliminate the obligation to deliver any information required to be
delivered under the related Intercreditor Agreement.


 


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


 






    -271-


     


    

 


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


 


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


 


(l)             
At any time that the Controlling Class Certificateholder is the holder of a majority of the Class F-RR Certificates and the Class
F-RR Certificates are the Controlling Class, such Controlling Class Certificateholder 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 electronic mail to trustadministrationgroup@wellsfargo.com),
the Trustee, the Master Servicer, the Special Servicer and the Operating Advisor. Notwithstanding anything to the contrary contained
herein, during such time as a Control Termination Event or Consultation Termination Event is in existence solely as a result of
the operation of clause (ii) of the definition of Control Termination Event and clause (ii) of the definition of
Consultation Termination Event, such Control Termination Event or Consultation Termination Event shall be deemed to no longer
be in existence and have not occurred with respect to any unaffiliated third party to whom the Controlling Class Certificateholder
that irrevocably waived its right to exercise any of the rights of the Controlling Class Certificateholder has sold or transferred
all or a portion of its interest in the Class F-RR 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, waive its right to appoint a Directing Certificateholder or cause the exercise
of the rights of the Directing Certificateholder) without regard to any prior waiver by the predecessor Controlling Class Certificateholder.
The Non-Waiving Successor shall also have the right to exercise any of the rights of the Controlling Class Certificateholder.
No Non-Waiving Successor described above shall have any consent rights with respect to any Mortgage Loan that became a Specially
Serviced Loan prior to the sale or transfer of the Class F-RR 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) the identity of the new Controlling Class and (ii) provide
to the Master Servicer, the Special Servicer and the Operating Advisor notice of such event and the identity and contact information
of the new Controlling Class Certificateholder (the cost of obtaining such information from DTC being an expense of the Trust).
The Certificate Administrator shall notify the Operating Advisor, the Master Servicer and the Special Servicer within ten (10)
Business Days of the existence or cessation of (i) any Control Termination Event, (ii) any Consultation Termination
Event or (iii) any Operating Advisor Consultation Event. Upon the Certificate Administrator’s


 






    -272-


     


    

 


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


 


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


 


If
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 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 that an Operating Advisor Consultation Event has occurred due to the reduction of the aggregate Certificate Balance
of the HRR Certificates to 25% or below of their aggregate Original Certificate Balance, taking into account the application of
any Cumulative Appraisal Reduction Amounts, such special notice shall state: “An Operating Advisor Consultation Event has
occurred because the aggregate Certificate Balance of the HRR Certificates has been reduced to 25% or below of their aggregate
Original Certificate Balance.”


 


The
Directing Holder shall not have any consent or consultation rights with respect to any Mortgage Loan determined to be an Excluded
Loan as to such party. 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 VRR 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 such Excluded Loan.


 


Section 3.24      
Intercreditor Agreements. (a)  Each of the Master Servicer and the Special Servicer acknowledges and agrees that
each Serviced Whole Loan being serviced under this Agreement and each Mortgage Loan with mezzanine debt is subject to the terms
and provisions of the related Intercreditor Agreement and each agrees to service each such Serviced Whole Loan and each Mortgage
Loan with mezzanine debt in accordance with the related Intercreditor Agreement and this Agreement, including, without limitation,
effecting distributions and allocating reimbursement of expenses in accordance with the related Intercreditor Agreement and, in
the event of any conflict between the provisions of this Agreement and the related Intercreditor Agreement, the related Intercreditor
Agreement shall govern. Notwithstanding anything contrary in this Agreement, each of the Master Servicer and Special Servicer
agrees not to take any action with respect to a Serviced Whole Loan or a Mortgage Loan with mezzanine debt


 






    -273-


     


    

 


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.


 


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


 






    -274-


     


    

 


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


 


(e)            
Notwithstanding anything in this Agreement to the contrary, (a)(i) with respect to any Non-Specially Serviced Loan the Special
Servicer (with respect to any Major Decision (other than with respect to actions described in subclauses (i) or (ii)
of clause (xiii) of the definition of “Major Decisions”, which the Master Servicer shall process without
first seeking the agreement of the Special Servicer) or Special Servicer Decision, unless the Master Servicer and the Special
Servicer mutually agree that, in connection with any modification, waiver or amendment that constitutes a Major Decision (other
than with respect to actions described in subclauses (i) or (ii) of clause (xiii) of the definition of “Major
Decisions”, which the Master Servicer shall process without first seeking the agreement of the Special Servicer) or Special
Servicer Decision, the Master Servicer shall process and determine whether to consent, subject to the consent of the Special Servicer,
to such modification, waiver or amendment) or the Master Servicer (with respect to any modification, waiver or amendment that
does not constitute a Major Decision or a Special Servicer Decision), or (ii) with respect to any Specially Serviced Loan, the
Special Servicer, as applicable, shall (1) to the extent the required notice address has been provided, provide copies of
any notice, information and report that it is required to provide to the Directing Holder 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 Directing Holder (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 continuance of a Control Termination Event or a Consultation Termination Event) and (2) 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 Directing Holder, the Master Servicer or the Special
Servicer, as applicable, 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 Master Servicer or the Special Servicer,
as applicable,


 






    -275-


     


    

 


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 Master Servicer or Special Servicer, as applicable, may make any Major Decision or take any action set forth in
the Asset Status Report before the expiration of the aforementioned ten (10) Business Day period if the Master Servicer or Special
Servicer, as applicable, determines that immediate action with respect thereto is necessary to protect the interests of the Certificateholders
and the related Companion Holder. In no event shall the Master Servicer or the Special Servicer, as applicable, be obligated at
any time to follow or take any alternative actions recommended by the related Companion Holder.


 


(f)             
In addition to the consultation rights of the holder of a Serviced Pari Passu Companion Loan provided in the immediately preceding
paragraph, such Companion Holder shall have the right to attend (in person or telephonically, in the discretion of the Master
Servicer or Special Servicer, as applicable) 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 two (2) Business
Days after receipt by the Master Servicer of the related Periodic Payment without the consent of the Master Servicer.


 


(h)            
[Reserved].


 


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


 


Section 3.25      
Rating Agency Confirmation. (a)  Notwithstanding the terms of any related Mortgage Loan documents or other provisions
of this Agreement, if any action under any Mortgage Loan documents or this Agreement requires Rating Agency Confirmation as a
condition precedent to such action, if the party (the “RAC Requesting Party”) required to obtain such Rating
Agency Confirmation from each Rating Agency has made a request to any Rating Agency for such Rating Agency Confirmation and, within
ten (10) Business Days of the Rating Agency Confirmation request being posted to the 17g-5 Information Provider’s Website,
such Rating


 






    -276-


     


    

 


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 confirm
(through direct communication and not by posting any confirmation on the 17g-5 Information Provider’s Website) that the
applicable Rating Agency has received the Rating Agency Confirmation request, and, if it has not, promptly request the related
Rating Agency Confirmation again (which may also be through direct communication). The circumstances described in the preceding
sentence are referred to in this Agreement as a “RAC No-Response Scenario.” Once the RAC Requesting Party has
sent a request for a Rating Agency Confirmation to the 17g-5 Information Provider, such RAC Requesting Party, may, but is not
required to send such request directly to the Rating Agencies in accordance with the procedures set forth in this Section 3.25.


 


If
there is no response to such Rating Agency Confirmation request within five (5) Business Days of such second request in a RAC
No-Response Scenario or if such Rating Agency has responded in a manner that indicates such Rating Agency is neither reviewing
such request nor waiving the requirement for Rating Agency Confirmation, then (x) with respect to any condition in any Mortgage
Loan document requiring such Rating Agency Confirmation or with respect to any other matter under this Agreement relating to the
servicing of the Mortgage Loans (other than as set forth in clause (y) below), the requirement to obtain a Rating
Agency Confirmation shall be deemed not to apply for such matter at such time (as if such requirement did not exist) with respect
to such Rating Agency and the Master Servicer (with respect to Non-Specially Serviced Loans, if the Master Servicer is processing
the action requiring Rating Agency Confirmation) or the Special Servicer (with respect to Specially Serviced Loans, REO Mortgage
Loans and Non-Specially Serviced Loans if the Special Servicer is processing the action requiring Rating Agency Confirmation with
respect to such Non-Specially Serviced Loans), as the case may be, may then take such action if the Master Servicer (with respect
to Non-Specially Serviced Loans, if the Master Servicer is processing the action requiring Rating Agency Confirmation) or the
Special Servicer (with respect to Specially Serviced Loans, REO Mortgage Loans and Non-Specially Serviced Loans if the Special
Servicer is processing the action requiring Rating Agency Confirmation with respect to such Non-Specially Serviced Loans), as
applicable, confirms its original determination (made prior to making such request) that taking the action with respect to which
it requested the Rating Agency Confirmation would still be consistent with the Servicing Standard, and (y) with respect to
a replacement of the Master Servicer or the Special Servicer, such condition shall be deemed not to apply (as if such requirement
did not exist) if (i) the applicable replacement master servicer or special servicer 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, (ii) 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 ratings downgrade or withdrawal) of securities in any other
commercial mortgage-backed securitization transaction serviced by such replacement master servicer or special servicer prior to
the time of determination, if KBRA is the non-responding Rating Agency or (iii) the applicable replacement master servicer or
special servicer has been appointed and currently serves as a master servicer or a 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 such replacement master servicer or special servicer as the sole or a material
factor in any qualification, downgrade or


 






    -277-


     


    

 





withdrawal of the ratings (or placement on “watch status” in contemplation
of a rating downgrade or withdrawal) of securities in a CMBS 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.


 


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


 


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


 


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


 


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


 


Section 3.26      
The Operating Advisor. (a)  The Operating Advisor shall promptly review (i) the actions of the Special Servicer
with respect to any Specially Serviced Loan and, during an Operating Advisor Consultation Event, the actions of the Special Servicer
with respect to Major Decisions relating to the Mortgage Loans when they are not a Specially Serviced Loan when a Major Decision
Reporting Package has been delivered (which review shall be performed in accordance with Section 3.08(a), Section 3.08(b),
Section 3.18(a), Section 3.19(d), Section 3.26 and Section 6.08), (ii) all reports
by the Special Servicer made available to Privileged Persons on the Certificate Administrator’s Website and that are relevant
to the Operating Advisor’s obligations hereunder and (iii) each Asset Status Report (during an Operating Advisor Consultation
Event) and each Final Asset Status Report delivered to the Operating Advisor by the Special Servicer. The Operating Advisor shall
perform its duties hereunder in accordance with the Operating Advisor Standard. In addition and for the avoidance of doubt, although
the Operating Advisor may have certain consultation duties with the Master Servicer with respect to certain


 






    -278-


     


    

 


Major Decisions processed
by the Master Servicer, the Operating Advisor will have no obligations or responsibility at any time to review or assess the actions
of the Master Servicer for compliance with the Servicing Standard, and the Operating Advisor is not required to consider such
Master Servicer actions in connection with any Operating Advisor Annual Report.


 


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


 


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


 






    -279-


     


    

 


31 in the prior
calendar year and is continuing in such capacity through the date of such Operating Advisor Annual Report; provided, further,
that the Operating Advisor shall prepare a separate Operating Advisor Annual Report relating to each Excluded Special Servicer
and any Excluded Special Servicer Loan(s) serviced by such Excluded Special Servicer. In preparing any Operating Advisor Annual
Report, the Operating Advisor shall not be required to report on instances of non-compliance with, or deviation 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. Subject to the restrictions in this Agreement, including, without limitation, this
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).
Such Operating Advisor Annual Report shall be delivered to 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)), with a copy of the final Operating Advisor Annual Report to the Special
Servicer; provided, further, 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 “asset-level basis” refers to the Special Servicer’s performance of
its duties as they relate to the Specially Serviced Loans (and, after the occurrence and continuance of an Operating Advisor Consultation
Event, also with respect to Major Decisions on Non-Specially Serviced Loans for which a Major Decision Reporting Package has been
delivered to the Operating Advisor), taking into account the Special Servicer’s specific duties under this Agreement as
well as the extent to which those duties were performed in accordance with the Servicing Standard, with reasonable consideration
by the Operating Advisor of any assessment of compliance report, attestation report, Major Decision Reporting Package, Asset Status
Report, Final Asset Status Report and any other information delivered to the Operating Advisor by the Special Servicer (other
than any communications between the Directing Certificateholder and the Special Servicer) pursuant to this Agreement.


 


(ii)              
If the Operating Advisor’s ability to perform its obligations in respect of the Operating Advisor Annual Report is limited
or prohibited due to the failure of a party hereto to timely deliver notice of action and information required to be delivered
to the Operating Advisor or because such information is inaccurate or incomplete, the Operating Advisor shall set forth such limitations
or prohibitions known to the Operating Advisor in the related Operating Advisor Annual Report and the Operating Advisor is not
subject to any liability arising from such limitations or prohibitions. The Operating Advisor may conclusively rely on the accuracy
and completeness of any information it is provided without liability for any such reliance thereunder.


 






    -280-


     


    

 


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


 


(iv)              
If 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 is not subject to any liability arising from such limitations or prohibitions.


 


(d)           
(i)  After the calculation has been finalized (and if an Operating Advisor Consultation Event is continuing prior to
the utilization) by the Special Servicer of any of the calculations related to (i) Appraisal Reduction Amounts calculated
by the Special Servicer, (ii) Collateral Deficiency Amounts calculated by the Special Servicer, (iii) Cumulative Appraisal Reduction
Amounts calculated by the Special Servicer or (iv) 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 no later than three
(3) Business Days after receipt of such calculations and any supporting or additional materials recalculate and review for accuracy
and consistency with this Agreement the mathematical calculations and the corresponding application of the non-discretionary portion
of the applicable formulas required to be utilized in connection with any such calculation.


 


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


 






    -281-


     


    

 


Operating Advisor and the Special Servicer and determine which
calculation is to apply (and shall provide prompt written notice of such determination to the Operating Advisor and the Special
Servicer). In making such determination, the Certificate Administrator may hire an independent third party to assist with any
such calculation at the expense of the Trust. The Certificate Administrator may conclusively rely on such third party calculation.


 


(e)            
Notwithstanding the foregoing, if no Operating Advisor Consultation Event is continuing, the Operating Advisor’s review
will be limited to an after-the-action review of any assessment of compliance, attestation report, Major Decision Reporting Package
relating to a Specially Serviced Loan, Final Asset Status Report and other information requested by and delivered to the Operating
Advisor by the Special Servicer or made available to Privileged Persons that are posted on the Certificate Administrator’s
Website during the prior calendar year (together with any additional information and material reviewed by the Operating Advisor)
and, therefore, it will have no involvement with respect to collateral substitutions, assignments, workouts, modifications, consents,
waivers, Insurance Policies, mortgagor substitutions, lease changes, additional borrower debt, defeasances, property management
changes, releases from escrow, assumptions or other similar actions that the Special Servicer may perform under this Agreement
and will have no obligations at any time with respect to any Non-Serviced Mortgage Loan. In addition, with respect to the Operating
Advisor’s review of net present value calculations as described above, the Operating Advisor’s recalculation shall
not take into account the reasonableness of Special Servicer’s property and borrower performance assumptions or other similar
discretionary portions of the net present value calculation.


 


(f)             
The Operating Advisor and its Affiliates shall keep all information appropriately labeled as “Privileged Information”
confidential and shall not disclose such Privileged Information to any other Person (including any Certificateholders, other than
the Directing Certificateholder), other than (i) to the extent expressly set forth herein, to the other parties to this Agreement
with a notice indicating that such information is Privileged Information, (ii) pursuant to a Privileged Information Exception
or (iii) where necessary to support specific findings or conclusions concerning allegations of deviations from the Servicing
Standard (A) in the Operating Advisor Annual Report or (B) in connection with a recommendation by the Operating Advisor to replace
the Special Servicer. Each party to this Agreement that receives “Privileged Information” from the Operating Advisor
with a notice stating that such information is Privileged Information shall not disclose such Privileged Information to any other
Person without the prior written consent of the Special Servicer and, unless a Control Termination Event is continuing, the Directing
Certificateholder (with respect to any Mortgage Loan other than a Non-Serviced Whole Loan, a Servicing Shift Whole Loan or 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 Operating Advisor gained from performing operating advisor functions for such Other
Securitizations are not imputed to 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.


 






    -282-


     


    

 


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


 


(h)            
As compensation for its activities hereunder, the Operating Advisor shall be entitled to receive the Operating Advisor Fee on
each Distribution Date with respect to each Mortgage Loan or REO Mortgage Loan. As to each Mortgage Loan and each REO Mortgage
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 Mortgage Loan, as the case may be, and in the same manner as
interest is calculated on the related Mortgage Loan or REO Mortgage 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 Mortgage Loan is computed. The Operating Advisor Fee shall be payable from funds on deposit in the
Collection Account as provided in Section 3.05(a)(ii).


 


The
Operating Advisor shall be entitled to reimbursement of any Operating Advisor Expenses provided for pursuant to Section 6.04(a)
and/or 6.04(b), 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), but, with respect to the period when
the outstanding Certificate Balances of the Control Eligible Certificates have not been reduced to zero as a result of the allocation
of Realized Losses to such Certificates, only to the extent such Operating Advisor Consulting Fee is actually received from the
related Mortgagor; provided, however, that to the extent such Operating Advisor Consulting Fee is incurred after
the outstanding Certificate Balances of the Control Eligible Certificates have been reduced to zero as a result of the allocation
of Realized Losses to such Certificates, such Operating Advisor Consulting Fee shall be payable in full to the Operating Advisor
as a Trust Fund expense. When the Operating Advisor has consultation obligations with respect to a Major Decision under this Agreement,
the Master Servicer or the Special Servicer, as the case may be, shall use commercially reasonable efforts to collect the applicable
Operating Advisor Consulting Fee from the related Mortgagor in connection with such Major Decision in accordance with the Servicing
Standard, but only to the extent not prohibited by the related Mortgage Loan documents. The Master Servicer or Special Servicer,
as the case may be, may waive or reduce the amount of any Operating Advisor Consulting Fee payable by the related Mortgagor if
it determines that such full or partial waiver is in accordance with the Servicing Standard, but in no event shall the Master
Servicer or the Special Servicer take any enforcement action with respect to the collection of such Operating Advisor Consulting
Fee other than requests for collection; provided that the Master Servicer or the Special Servicer, as applicable, shall
consult, on a non-binding basis, with the Operating Advisor prior to any such waiver or reduction. Notwithstanding the foregoing,
the Operating Advisor will have no obligations (with limited exceptions) or consultation rights as Operating Advisor with respect
to:


 






    -283-


     


    

 


(i) any Non-Serviced Whole Loan or any related REO Property or (ii) with respect to any Serviced AB Whole Loan,
if no Control Appraisal Period is continuing; provided, further, that the Operating Advisor will not be entitled
to an Operating Advisor Consulting Fee with respect to any Non-Serviced Whole Loan.


 


(i)             
During a Consultation Termination Event, the Operating Advisor may be removed upon (i) the written direction of Certificateholders
evidencing not less than 25% of the Voting Rights (taking into account the application of Cumulative Appraisal Reduction Amounts
to notionally reduce the Certificate Balances of Classes to which such Cumulative 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 applicable Certificateholders of such request by posting such notice on the Certificate Administrator’s Website in
accordance with Section 3.13(b), and concurrently by mail, and conduct the solicitation of votes of all applicable
Certificates in such regard. Upon the vote or written direction of Holders of at least 75% of the Voting Rights (taking into account
the application of Cumulative Appraisal Reduction Amounts to notionally reduce the Certificate Balances of Classes to which such
Cumulative Appraisal Reduction Amounts are allocable), the Trustee shall immediately terminate all of the rights and obligations
of the Operating Advisor under this Agreement (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)) by prior written notice to the Operating Advisor, and the proposed successor operating advisor will be appointed.


 


(j)             
After the occurrence of an Operating Advisor Termination Event, the Trustee may, and upon the written direction of Certificateholders
representing at least 25% of the Voting Rights (taking into account the application of any Cumulative 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 shall, as soon as possible,
give written notice of the termination and appointment to the Special Servicer, the Master Servicer, the Certificate Administrator,
the 17g-5 Information Provider (for posting to the 17g-5 Information Provider’s Website), the Depositor, the Directing Certificateholder
(only for so long as no Consultation


 






    -284-


     


    

 


Termination Event is continuing), the Risk Retention Consultation Party, any Companion Holder
and the Certificateholders.


 


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


 


(l)             
If no Control Termination Event is continuing, the Directing Certificateholder will 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 shall be deemed to have been granted if no objection
is made within ten (10) Business Days following the Directing Certificateholder’s receipt of the request for consent
and, if granted or deemed granted, such consent cannot thereafter be revoked or withdrawn.


 


(m)          
The Operating Advisor may resign from its obligations and duties hereby imposed on it (a) upon thirty (30) days prior written
notice to the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Asset Representations
Reviewer, the Directing Certificateholder and the Risk Retention Consultation Party, if applicable, if the Operating Advisor has
secured a replacement operating advisor that is an Eligible Operating Advisor, (b) upon the appointment of, and the acceptance
of such appointment by, a successor Operating Advisor that is an Eligible Operating Advisor and (c) receipt by the Trustee of
Rating Agency Confirmation from each Rating Agency. If no successor operating advisor has been appointed and has accepted such
appointment within thirty (30) days of receipt by the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate
Administrator, the Asset Representations Reviewer, the Risk Retention Consultation Party and the Directing Certificateholder of
the resigning Operating Advisor’s notice of resignation, the resigning Operating Advisor may petition a 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 has 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(m).


 


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


 






    -285-


     


    

 


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


 


(p)           
With respect to the determination of whether an Operating Advisor Consultation Event has occurred and is continuing, or has terminated,
each of the Special Servicer and the Operating Advisor may 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 during an Operating Advisor Consultation Event, each of the Special Servicer and the Operating Advisor will have no obligation
to perform any such duties until the receipt of such notice or actual knowledge that the Certificate Administrator has posted
notice of an Operating Advisor Consultation Event to the Certificate Administrator’s Website pursuant to Section 3.23(m).


 


(q)           
Neither the Operating Advisor nor any of its Affiliates shall make any investment in any Class of Certificates.


 


(r)            
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(m) of this Agreement and the
Trustee shall appoint a successor operating advisor subject to and in accordance with this Section 3.26(r). Notwithstanding
the foregoing, if the Trustee is unable to find a successor operating advisor within 30 days of the termination of the Operating
Advisor, the Depositor shall be permitted to find a replacement.


 


(s)            
The Operating Advisor 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 Agreement; provided that no agent or subcontractor
may (i) be affiliated with a Mortgagor, Sponsor, Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator,
the Trustee, the Directing Certificateholder or any of their respective Affiliates or (ii) have been paid any fees, compensation
or other remuneration by an Underwriter, Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator,
the Trustee, the Directing Certificateholder or any of their respective Affiliates in connection with due diligence or other services
with respect to any Mortgage Loan 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 may
enter into an agreement with any agent or subcontractor providing for indemnification of the Operating Advisor


 






    -286-


     


    

 


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


 


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


 


(b)           
No provision of this Agreement shall be construed to relieve the Companion Paying Agent from liability for its negligent failure
to act, bad faith or its own willful misfeasance; provided, however, that the duties and obligations of the Companion
Paying Agent shall be determined solely by the express provisions of this Agreement. The Companion Paying Agent is not 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,
the Master Servicer, as the Companion Paying Agent, shall be deemed simultaneously to resign or be removed.


 


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


 


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


 


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


 


For
the avoidance of doubt, any notices or information required to be delivered pursuant to this Agreement by any party hereto to
a Companion Holder with respect to a Companion Loan that has been included in an Other Securitization shall be provided to the
Other

Servicer (which, unless required by the related Intercreditor Agreement to be sent to additional parties, shall be satisfied
by the delivery to the “master servicer” under the related Other Pooling and Servicing Agreement) under the Other
Pooling and Servicing Agreement.


 


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


 


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


 


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


 


(d)           
In connection with the sale of any Non-Serviced Whole Loan by any Non-Serviced Special Servicer, upon receipt of any notices or
materials required to be furnished by the Non-Serviced Special Servicer to the holder of the related Non-Serviced Mortgage Loan
pursuant to the related Intercreditor Agreement, the Special Servicer shall, if no Control Termination Event is continuing, forward
such materials to the Directing Certificateholder for its consent, if such consent is required. The Special Servicer may (with
the consent of the Directing Certificateholder if no Control Termination Event is continuing) waive any timing or delivery requirements
related to such sale to the extent set forth in the related Intercreditor Agreement.


 


(e)            
With respect to any Non-Serviced Mortgage Loan, the Directing Certificateholder, if no Consultation Termination Event is continuing,
or the Special Servicer, during a Consultation Termination Event, shall be entitled to exercise any consultation rights held by
the holder of such Mortgage Loan in its capacity as a “Non-Controlling Note Holder” (or similar term identified in
the related Intercreditor Agreement) under the related Intercreditor Agreement.


 


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


 


(g)            
On the Servicing Shift Securitization Date, (i) the Custodian shall, upon receipt of a Request for Release transfer the related
Mortgage File (other than the note(s)


 






    -288-


     


    

 


designating the related Servicing Shift Mortgage Loan), the original of which shall be retained
by the Custodian) for the related Servicing Shift Whole Loan to the related Non-Serviced Trustee under the related Non-Serviced
PSA and retain a copy of such Mortgage File and (ii) the Master Servicer shall, upon receipt of notice from the Mortgage Loan

(xii) of the definition of “Mortgage File” for the related Servicing Shift Whole Loan, to the related Non-Serviced
Master Servicer on the related Servicing Shift Securitization Date.


 


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


 


Promptly
upon any change in the identity of the Master Servicer, the successor master servicer shall deliver notice of such change (together
with the contact information of such successor Master Servicer) to each Non-Serviced Trustee, Non-Serviced Certificate Administrator,
Non-Serviced Special Servicer, Non-Serviced Master Servicer and Non-Serviced Operating Advisor.


 


Section 3.30      
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 3.30 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 3.30 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 will have any
obligations to separately label and deliver any Excluded Information in accordance with this Section 3.30 until such
party has received written notice with respect to the related Excluded Controlling Class Loan in the form of Exhibit P-1B
to this Agreement. Nothing set forth in this Agreement prohibits the Directing Holder or any Controlling Class Certificateholder
from receiving, requesting or reviewing any Excluded Information relating to any Excluded Controlling Class Loan with respect


 






    -289-


     


    

 


to which the Directing Holder or such Controlling Class Certificateholder is not a Borrower Party and, if such Excluded Information

that is not a Borrower Party with respect to the related Excluded Controlling Class Loan shall be permitted to obtain such
information in accordance with Section 3.13(a).


 


(b)           
Nothing set forth in this Agreement shall prohibit the Directing Holder or any Controlling Class Certificateholder from receiving,
requesting or reviewing any Excluded Information relating to any Excluded Controlling Class Loan with respect to which the
Directing Holder or such Controlling Class Certificateholder is not a Borrower Party and, if such Excluded Information is
not available to such Excluded Controlling Class Holder via the Certificate Administrator’s Website, such Directing
Certificateholder or Controlling Class Certificateholder that is not a Borrower Party with respect to the related Excluded
Controlling Class Loan shall be permitted to obtain such information in accordance with Section 4.02(f).


 


Section 3.31      
Credit Risk Retention.


 


(a)

with the Depositor and the Mortgage Loan Sellers (the “Credit Risk Retention Compliance Agreement”).


 


(b)           
None of the Master Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator
or the Custodian shall be obligated to monitor, supervise or enforce the performance of any party under the Credit Risk Retention
Compliance Agreement.


 


Section 3.32      
Resignation Upon Prohibited Risk Retention Affiliation. Under the Risk Retention Rule, any Subsequent Third Party Purchaser
is prohibited from being Risk Retention Affiliated with, among other persons, the Master Servicer, the Trustee, the Certificate
Administrator, the Operating Advisor or the Asset Representations Reviewer. As long as the prohibition exists under the Risk Retention
Rule, upon the occurrence of (i) a Servicing Officer of the Master Servicer or a Responsible Officer of the Certificate Administrator
or the Trustee, as applicable, obtaining actual knowledge that the Master Servicer, the Certificate Administrator or the Trustee,
as applicable, is or has become a Risk Retention Affiliate of a Subsequent Third Party Purchaser (an “Impermissible TPP
Affiliate”), (ii) the Master Servicer, the Certificate Administrator or the Trustee receiving written notice by any
other party to this Agreement, the Subsequent Third Party Purchaser, any Sponsor or any Underwriter or Initial Purchaser that
the Master Servicer, the Certificate Administrator or the Trustee, as applicable, is or has become an Impermissible TPP Affiliate,
or (iii) an officer or manager of the Operating Advisor or the Asset Representations Reviewer that is responsible for performing
the duties of the Operating Advisor or the Asset Representations Reviewer obtaining actual knowledge that it is or has become
a Risk Retention Affiliate of or Risk Retention Affiliated with any Subsequent Third Party Purchaser or any other party to this
Agreement (an “Impermissible Operating Advisor Affiliate” or “Impermissible Asset Representations
Reviewer Affiliate”, respectively; and either of an Impermissible TPP Affiliate, an Impermissible Operating Advisor
Affiliate and an Impermissible Asset Representations Reviewer Affiliate being an “Impermissible Risk Retention Affiliate”),
then, in each such case the Impermissible Risk Retention Affiliate shall promptly notify the


 






    -290-


     


    

 


Retaining Sponsor and the other parties
to this Agreement and resign in accordance with Section 3.26, Section 6.05, Section 8.07 or
Section 12.03, as applicable. The resigning Impermissible Risk Retention Affiliate shall bear all reasonable out-of-pocket
costs and expenses of each other party to this Agreement, the Trust and each Rating Agency in connection with such resignation
as and to the extent required under this Agreement; provided, however, that if the affiliation causing an Impermissible
Risk Retention Affiliate is the result of the Subsequent Third Party Purchaser acquiring an interest in such Impermissible Risk
Retention Affiliate or an affiliate of such Impermissible Risk Retention Affiliate, then such costs and expenses will be an expense
of the Trust.


 


Section 3.33           
Litigation Control.


 


(a)            
With respect to any Serviced Mortgage Loan (other than any Excluded Special Servicer 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, other obligor on the related Mortgage Note or any Affiliates
thereof (each a “Borrower-Related Party”) against the Trust (including, without limitation, any action in which
both the Trust and the Master Servicer are named) 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 (or the enforcement of 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 related 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 reasonably 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)           
With respect to any Non-Specially Serviced Loan and 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 Section 3.33(a) above, the Master Servicer shall (i) provide quarterly (unless requested in writing from time to time
on a more frequent basis) status reports to the Special Servicer regarding such Trust-Related Litigation; (ii) use reasonable
efforts 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 such lawsuit, consult with, and take direction from, the Special Servicer with respect to material
decisions and material monetary settlements related to the interests of the Trust in such Trust-Related Litigation, including
but not limited to the selection of counsel. If and/or when the Trust and/or the Special Servicer are named, the Special Servicer
shall assume control of the Trust-Related Litigation as provided in Section 3.33(a) above, the Master Servicer shall no
longer have the reporting obligations set forth above and the Special Servicer’s selection of counsel shall be subject to
the consent of the Master Servicer which consent shall not be unreasonably withheld. Further, if there are claims against the
Master Servicer, the Trust, and the Special Servicer, each


 






    -291-


     


    

 


party at the request of any other such party shall enter into a joint
defense agreement in accordance with Section 3.33(h) below.


 


(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 (A) it has notified in writing the Directing
Holder (prior to a Control Termination Event and other than with respect to an Excluded Loan) (to the extent the identity of the
Directing Holder 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 Holder) 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 (B) the Directing Holder (prior to a Control Termination Event and other than
with respect to an Excluded Loan) 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 Holder 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 Holder 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 any related Serviced Companion Loan holders, the Special
Servicer may take such action without waiting for the Directing Holder’s response.


 


(d)           
Notwithstanding anything to the contrary in this Section 3.33, neither the Special Servicer nor the Master Servicer shall
follow any advice, direction or consultation provided by the Directing Holder or the Risk Retention Consultation Party (or any
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 Whole Loan, expose any Certificateholder or any party to this Agreement or their
Affiliates, officers, directors or agents to any claim, suit or liability, cause any Trust REMIC created hereunder to fail to
qualify as a REMIC, or any Grantor Trust created hereunder to fail to qualify as a grantor trust for federal income tax purposes
or 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 applicable, responsibilities
under this Agreement.


 


(e)            
Notwithstanding the right of the Special Servicer provided under this Section 3.33 to represent the interests of the Trust
in Trust Related Litigation, the Master Servicer shall retain the right at all times to make determinations relating to material
and direct claims against the Master Servicer where a settlement by the Special Servicer has not otherwise been resolved pursuant
to the terms of subsection (g) below, including but not limited to the right to engage separate counsel, to make settlement decisions
and to appear in any proceeding on its own behalf. The cost related to or incurred in connection with exercising such rights shall
be subject to indemnification as and to the extent provided in this Agreement.


 






    -292-


     


    

 


(f)             
Further, nothing in this Section 3.33 shall require the Master Servicer or the Special Servicer to take or fail to take
any action which, in the Master Servicer’s or Special Servicer’s reasonable judgment, may (i) cause any Trust REMIC
created hereunder to fail to qualify as a REMIC, or any Grantor Trust created hereunder to fail to qualify as a grantor trust
for federal income tax purposes, result in the imposition of “prohibited transaction” or “prohibited contribution”
tax under the Code, or otherwise result in a violation of the REMIC Provisions, (ii) cause the Master Servicer or the Special
Servicer to violate the Servicing Standard, (iii) result in a violation of applicable law or the Mortgage Loan documents or (iv)
subject the Master Servicer or the Special Servicer to liability or materially expand the scope of the Master Servicer’s

the Master Servicer and the Special Servicer deem it appropriate, the Master Servicer and the Special Servicer shall (i) use reasonable
efforts to enter into a joint defense agreement and (ii) otherwise cooperate with each other to afford the Master Servicer and
the Special Servicer the rights afforded to such party in this Section 3.33.

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.


 


(j)

Trustee, the Certificate Administrator, the Custodian or the Operating Advisor, as applicable, in its individual capacity or (D)
prepare, execute or deliver any government filings, forms, permits, registrations or other documents or take any other similar
action with the intent to cause, and that actually causes, the Certificate Administrator, the Trustee or the Custodian, as applicable,
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 Certificate Administrator, the Trustee or the Custodian, as applicable,

to the extent required in Section 3.33(c)) from initiating any action, suit, litigation or proceeding in its name as representative
of the Trustee of the Trust. References to Mortgage Loans (including references to Mortgagors, guarantors, obligors and Mortgaged

Section 3.34      
Certain Matters with Respect to Joint Mortgage Loans.


 


(a)            
If a Mortgage Loan Seller with respect to a Joint Mortgage Loan (a “Repurchasing Mortgage Loan Seller”) repurchases,
or substitutes for, the Mortgage Note(s) (as such term is defined in this Section 3.34(a)) (a “Repurchased
Note”) related to such Joint Mortgage Loan that it sold to the Depositor, but the other Mortgage Loan Seller with respect
to such Joint Mortgage Loan does not repurchase, or substitute for, the Mortgage Note(s) related to such Joint Mortgage Loan that
it sold to the Depositor, the provisions of this Section 3.34 shall apply prior to the adoption, pursuant to Section 13.01(l),
of any amendment to this Agreement that provides otherwise, and except as provided herein, such Mortgage Loan shall continue to
be serviced under this Agreement. Each Mortgage Loan Seller of a Joint Mortgage Loan has agreed pursuant to the terms of the related
Mortgage Loan Purchase Agreement that the terms set forth in this Section 3.34 with respect to the servicing and administration
of such Joint Mortgage Loan shall apply if one or more of the Mortgage Notes related to such Joint Mortgage Loan has been repurchased
or, by way of substitution, otherwise removed from the Trust and at least one other Mortgage Note related to such Joint Mortgage
Loan is included in the Trust until such time as all of the Mortgage Notes related to such Joint Mortgage Loan are no longer included
in the Trust. For purposes of this Section 3.34, Section 13.01(l) and Section 13.08(a) only,
“Mortgage Note” shall mean with respect to any Joint Mortgage Loan, each original promissory note that collectively
represents the Mortgage Note (as defined in Article I) with respect to such Joint Mortgage Loan and shall not be a collective
reference to such promissory notes.


 


(b)           
Custody of and record title under the Mortgage Loan documents with respect to the applicable Joint Mortgage Loan shall be held
exclusively by the Custodian as provided under this Agreement, except that the Repurchasing Mortgage Loan Seller shall hold and
retain title to its original Repurchased Note(s) and any related endorsements thereof.


 


(i)            
All of the Mortgage Notes with respect to any Joint Mortgage Loan shall be of equal priority, and no portion of any Mortgage Note
shall have priority or preference over any other portion of the other Mortgage Notes or security therefor. Payments from the related
Mortgagor (including, without limitation, any Penalty Charges) or any other amounts received with respect to each Mortgage Note
shall be collected as provided in this Agreement by the Master Servicer and shall be applied upon receipt by the Master Servicer
pro rata to each related Mortgage Note based on its respective Mortgage Loan Seller Percentage Interest, subject to Section 3.34(b)(ii).
Payments or any other amounts received with respect to the related Repurchased Note shall be held in trust for the benefit of
the applicable Repurchasing Mortgage Loan Seller and remitted (net of its pro rata share of amounts payable at the Administrative
Cost Rate and any other amounts due to the Master Servicer or Special Servicer) to the applicable Repurchasing Mortgage Loan Seller
or its designee by the Master Servicer on each Distribution Date pursuant to instructions


 






    -295-


     


    

 


provided by the applicable Repurchasing
Mortgage Loan Seller and deposited and applied in accordance with this Agreement, subject to Section 3.34(b)(ii).
If any Joint Mortgage Loan to which this Section 3.34 applies becomes an REO Loan, payments or any other amounts received
with respect to any such Joint Mortgage Loan shall be collected and shall be applied upon receipt by the Master Servicer pro
rata to each related Mortgage Note based on its respective Mortgage Loan Seller Percentage Interest, subject to Section 3.34(b)(ii).
Any Appraisal Reduction Amounts calculated with respect to any Joint Mortgage Loan subject to this Section 3.34 shall
be allocated to each related Mortgage Note, pro rata based upon the respective unpaid principal balances thereof.


 


(ii)            
If the Master Servicer or the Special Servicer, as applicable, receives an aggregate payment of less than the aggregate amount
due under any such Joint Mortgage Loan at any particular time, the applicable Repurchasing Mortgage Loan Seller shall receive
from the Master Servicer an amount equal to its Mortgage Loan Seller Percentage Interest of such payment. All expenses, losses
and shortfalls relating solely to such Joint Mortgage Loan including, without limitation, losses of principal or interest, Nonrecoverable
Advances, interest on Servicing Advances, Special Servicing Fees, Workout Fees and Liquidation Fees (including any such fees related
to the applicable Mortgage Notes), shall be allocated between the holders of the related Mortgage Notes pro rata based
upon the respective unpaid principal balances thereof. In no event shall any costs, expenses, fees or any other amounts related
to any Mortgage Loan or Joint Mortgage Loan other than the applicable Joint Mortgage Loan be deducted from payments or any other
amounts received with respect to such Joint Mortgage Loan and payable to the applicable Repurchasing Mortgage Loan Seller.


 


(iii)            
A Joint Mortgage Loan to which this Section 3.34 applies shall be serviced for the benefit of the applicable Repurchasing
Mortgage Loan Seller and the Certificateholders pursuant to the terms and conditions of this Agreement in accordance with the
Servicing Standard and in accordance with the provisions herein as if (A) such Joint Mortgage Loan were a Serviced Whole Loan
(and, if such Joint Mortgage Loan is part of a Serviced Whole Loan, such Joint Mortgage Loan shall continue to be serviced and
administered under the applicable Intercreditor Agreement), (B) the related Mortgage Note(s) not repurchased were (1) a Serviced
Pari Passu Mortgage Loan and (2) the only Mortgage Loan that is part of such Joint Mortgage Loan (or related Serviced Whole Loan),
and (C) the related Repurchased Note were a Serviced Pari Passu Companion Loan. No Repurchasing Mortgage Loan Seller shall be
permitted to terminate the Master Servicer, the Special Servicer or the Operating Advisor as servicer, special servicer or operating
advisor, respectively, of the related Repurchased Note. All rights of the mortgagee under each such Joint Mortgage Loan shall
be exercised by the Master Servicer or the Special Servicer, as applicable, on behalf of the Trust to the extent of its interest
therein and the applicable Repurchasing Mortgage Loan Seller in accordance with this Agreement.


 


(iv)            
The related Repurchasing Mortgage Loan Seller shall be treated hereunder as if it were a Serviced Pari Passu Companion Loan holder
on a pari passu basis. Funds collected by the Master Servicer or the Special Servicer, as applicable, and applied to the
applicable Mortgage Notes shall be deposited and disbursed in accordance with the provisions hereof relating to holders of promissory
notes comprising Serviced Whole


 






    -296-


     


    

 


Loans that are pari passu in right of payment. Compensation shall be paid to the Master
Servicer, the Special Servicer and the Operating Advisor with respect to each Repurchased Note as provided in this Agreement as
if each such Repurchased Note were a Serviced Pari Passu Companion Loan. None of the Trustee, the Certificate Administrator, the
Custodian, the Master Servicer, the Special Servicer or the Operating Advisor shall have any obligation to make P&I Advances
with respect to any Repurchased Note or, if no related Mortgage Note is part of the Trust, a Servicing Advance with respect to
any Repurchased Note. Except as otherwise specified herein, the Master Servicer and the Special Servicer shall have no reporting
requirement with respect to any Repurchased Note other than to deliver to the related Repurchasing Mortgage Loan Seller any document
as is required to be delivered to a holder of a Serviced Pari Passu Companion Loan hereunder.


 


(v)            
Notwithstanding any of the foregoing to the contrary, with respect to The Grace Building Mortgage Loan, the terms of the related
Intercreditor Agreement shall continue to apply to all of the Mortgage Notes comprising such Mortgage Loan, including any Repurchased
Note.


 


(c)            
If any non-repurchased Mortgage Note relating to a Joint Mortgage Loan to which this Section 3.34 applies is a Specially
Serviced Loan, then any related Repurchased Note shall also be a Specially Serviced Loan under this Agreement. The Special Servicer
shall cause such related Repurchased Note to be specially serviced for the benefit of the applicable Repurchasing Mortgage Loan
Seller in accordance with the terms and provisions set forth in this Agreement and shall be entitled to any Special Servicing
Fee, Workout Fee or Liquidation Fee payable to the Special Servicer under this Agreement as with respect to a Serviced Pari Passu
Companion Loan.


 


(d)           
If (A) the Master Servicer shall pay any amount to any Repurchasing Mortgage Loan Seller pursuant to the terms hereof in the belief
or expectation that a related payment has been made or will be received or collected in connection with any or all of the applicable
Mortgage Notes and (B) such related payment is not received or collected by the Master Servicer, then the applicable Repurchasing
Mortgage Loan Seller shall promptly on demand by the Master Servicer return such amount to the Master Servicer. If the Master
Servicer determines at any time that any amount received or collected by the Master Servicer in respect of any Joint Mortgage
Loan to which this Section 3.34 applies must be returned to the related Mortgagor or paid to any other person or entity
pursuant to any insolvency law or otherwise, notwithstanding any other provision of this Agreement, the Master Servicer shall
not be required to distribute any portion thereof to the related Repurchasing Mortgage Loan Seller, and such Repurchasing Mortgage
Loan Seller shall promptly on demand by the Master Servicer repay (which obligation shall survive the termination of this Agreement)
any portion thereof that the Master Servicer shall have distributed to such Repurchasing Mortgage Loan Seller, together with interest
thereon at such rate, if any, as the Master Servicer may pay to the related Mortgagor or such other person or entity with respect
thereto.


 


(e)            
Subject to this Agreement (including, without limitation, the consent and consultation rights of the Directing Holder and any
consultation rights of the Operating Advisor), the Master Servicer or the Special Servicer, as applicable, on behalf of the holders
of any of the Repurchased Notes, shall have the exclusive right and obligation to (i) administer, service and


 






    -297-


     


    

 


make all decisions
and determinations regarding the related Joint Mortgage Loan and (ii) enforce the applicable Mortgage Loan documents as provided
hereunder. Without limiting the generality of the preceding sentence, the Master Servicer or the Special Servicer, as applicable,
may agree to any modification, waiver or amendment of any term of, forgive interest on and principal of, capitalize interest on,
permit the release, addition or substitution of collateral securing, and/or permit the release of the related Mortgagor on or
any guarantor of any Joint Mortgage Loan it is required to service and administer as contemplated by this Section 3.34,
without the consent of the related Repurchasing Mortgage Loan Seller, subject, however, to the terms of this Agreement as they
pertain to a Serviced Pari Passu Companion Loan.


 


(f)             
In taking or refraining from taking any action permitted hereunder, the Master Servicer and the Special Servicer shall each be
subject to the same degree of care with respect to the administration and servicing of the Joint Mortgage Loans to which this
Section 3.34 applies as is consistent with this Agreement and shall be liable to any Repurchasing Mortgage Loan Seller
only to the same extent as set forth herein with respect to any holder of a Serviced Pari Passu Companion Loan.


 


(g)            
If the Trustee, the Master Servicer or the Special Servicer has made a Servicing Advance with respect to any Repurchased Note
which would otherwise be reimbursable to such advancing party under this Agreement, and such Advance is determined to be a Nonrecoverable
Advance, the applicable Repurchasing Mortgage Loan Seller shall reimburse the Trust in an amount equal to such Repurchasing Mortgage
Loan Seller’s Mortgage Loan Seller Percentage Interest of such Nonrecoverable Advance with interest thereon. Notwithstanding
the foregoing, the applicable Repurchasing Mortgage Loan Seller shall not be obligated to reimburse the Trustee, the Master Servicer
or the Special Servicer (and amounts due to the applicable Repurchasing Mortgage Loan Seller shall not be offset) for Advances
or interest thereon or any amounts related to any Mortgage Loans or any other Joint Mortgage Loan other than such amounts relating
to the applicable Repurchased Note. To the extent that the applicable Repurchasing Mortgage Loan Seller reimburses any such Nonrecoverable
Advances and such amounts are subsequently recovered, the applicable Repurchasing Mortgage Loan Seller shall receive a reimbursement
from such recovery based on its Mortgage Loan Seller Percentage Interest of such recovery. This reimbursement right shall not
limit the Trustee’s, the Master Servicer’s or the Special Servicer’s rights to reimbursement under this Agreement.
Notwithstanding anything to the contrary contained herein, the total liability of each Repurchasing Mortgage Loan Seller shall
not exceed an amount equal to its Mortgage Loan Seller Percentage Interest of the amount to be reimbursed.


 


(h)            
Each Repurchasing Mortgage Loan Seller shall have the right to assign the related Repurchased Note; provided that the assignee
of the related Repurchased Note shall agree in writing to be bound by the terms of this Agreement.


 


(i)             
The Master Servicer and the Special Servicer shall, in connection with their servicing and administrative duties under this Agreement,
exercise efforts consistent with the Servicing Standard to execute and deliver, on behalf of each Repurchasing Mortgage Loan Seller
as a holder of a pari passu interest in the applicable Joint Mortgage Loan, any and all financing statements, continuation
statements and other documents and instruments necessary to maintain the lien created by any Mortgage or other security document
related to the applicable Joint


 






    -298-


     


    

 


Mortgage Loan on the related Mortgaged Property and related collateral, any and all modifications,
waivers, amendments or consents to or with respect to the related Joint Mortgage Loan documents, and any and all instruments of
satisfaction or cancellation, or of full release or discharge, and all other comparable instruments with respect to the related
Repurchased Note or related Repurchased Notes and the related Mortgaged Property all in accordance with, and subject to, the terms
of this Agreement. Each Repurchasing Mortgage Loan Seller agrees to furnish, or cause to be furnished, to the Master Servicer
and the Special Servicer any powers of attorney or 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 under this Agreement related to the
applicable Joint Mortgage Loan; provided that such Repurchasing Mortgage Loan Seller shall not be liable, and shall be
indemnified by the Master Servicer or the Special Servicer, as applicable, for any negligence with respect to, or misuse of, any
such power of attorney by the Master Servicer or the Special Servicer, as the case may be; and further provided that the Master
Servicer or the Special Servicer, without the written consent of the applicable Repurchasing Mortgage Loan Seller, shall not initiate
any action in the name of such Repurchasing Mortgage Loan Seller without indicating its representative capacity or take any action
with the intent to cause and that actually causes, such Repurchasing Mortgage Loan Seller to be registered to do business in any
state.


 


(j)             
Pursuant to the related Mortgage Loan Purchase Agreement, the applicable Repurchasing Mortgage Loan Seller is required to deliver
to the Master Servicer or the Special Servicer, as applicable, the Mortgage Loan documents related to the applicable Repurchased
Note, any requests for release and any court pleadings, requests for trustee’s sale or other documents necessary to the
foreclosure or trustee’s sale in respect of the related Mortgaged Property or to any legal action or to enforce any other
remedies or rights provided by the Mortgage Note(s) or the Mortgage(s) or otherwise available at law or equity with respect to
the related Repurchased Note.

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


 






    -303-


     


    

 


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 Section 4.01(a), Section 4.01(d),
and Section 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 pro rata portion of the Interest Distribution Amount in respect of (i) in the case
of the Class LA-1, Class LA-2, Class LA-3, Class LA-SB and Class LA-S Uncertificated Interests, the Class X-A
Certificates, (ii) in the case of the Class LB Uncertificated Interests and Class LC Uncertificated Interests,
the Class X-B Certificates and (iii) in the case of the Class LD and Class LE Uncertificated Interests, the Class X-D
Certificates, in each case, computed based on an interest rate equal to the excess of the WAC 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 Section 4.04(b) and Section 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 shall be the rate per annum set forth in the Preliminary
Statement hereto.


 


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 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)           
While 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


 






    -304-


     


    

 


other than reimbursement of Realized Losses and other amounts provided
for in this Section 4.01 and the last sentence of Section 4.04(a).


 


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


 


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,
and with respect to any principal prepayment on any Mortgage Loan and with respect to any Class of Class A-1, Class A-2,
Class A-3, Class A-SB, Class A-S, Class B, Class C, Class D and Class E Certificates is a fraction
(a) whose numerator is the greater of (x) zero and (y) the difference between (i) the Pass-Through Rate of such
Class of Certificates and (ii) the Discount Rate used in accordance with the related Mortgage Loan documents in calculating
the Yield Maintenance Charge with respect to such principal prepayment and (b) whose denominator is the greater of zero and
the difference between (i) the Mortgage Rate on such Mortgage Loan (or with respect to any Mortgage Loan that is part of
a Serviced Whole Loan, the Mortgage Rate of such Serviced Whole Loan) and (ii) the Discount Rate used in accordance with
the related Mortgage Loan documents in calculating the Yield Maintenance Charge with respect to such principal prepayment; provided,
however, that under no circumstances shall the Base Interest Fraction be greater than 1.0 or less than zero. If such Discount
Rate is greater than or equal to the lesser of (x) the Mortgage Rate on the related Mortgage Loan or Serviced Whole Loan,
as applicable, and (y) the Pass-Through Rate described in the preceding sentence, then the Base Interest Fraction shall equal
zero; provided that if such


 






    -305-


     


    

 


Discount Rate is greater than or equal to the Mortgage Rate on such Mortgage Loan or Serviced
Whole Loan, as applicable, but less than the Pass-Through Rate described in the preceding sentence, then the Base Interest Fraction
shall equal 1.0. If a Mortgage Loan provides for a step-up in the Mortgage Rate, then the Mortgage Rate used in the determination
of the Base Interest Fraction shall be the Mortgage Rate in effect at the time of the prepayment.


 


For
purposes of the preceding paragraph, the relevant “Discount Rate” in connection with any Yield Maintenance
Charge collected on any prepaid Mortgage Loan or REO Mortgage Loan and distributable on any Distribution Date shall be a rate
per annum equal to (i) if a discount rate was used in the calculation of the applicable Yield Maintenance Charge pursuant
to the terms of the relevant Mortgage Loan or REO Mortgage Loan, as the case may be, such discount rate (as reported by the Master
Servicer), converted (if necessary) to a monthly equivalent yield, or (ii) if a discount rate was not used in the calculation
of the applicable Yield Maintenance Charge pursuant to the terms of the relevant Mortgage Loan or REO Mortgage 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 Servicer shall select a comparable publication as the source of the
applicable yields of U.S. Treasury constant maturities, and the Servicer shall incur no liability with respect thereto. The Servicer
shall notify the Certificate Administrator in writing of its designation of an alternate index and the Certificate Administrator
shall post same on its website as a “special notice”.


 


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


 


(ii)              
All distributions of Yield Maintenance Charges made (i) in respect of the respective Classes of Certificates on each Distribution
Date pursuant to Section 4.01(e) shall first be deemed to be distributed from the related Loan REMIC to the Lower-Tier
REMIC in respect of the related Loan REMIC Regular Interest, if applicable, and then 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.


 






    -306-


     


    

 


(f)             
On each Distribution Date, the Certificate Administrator shall determine if there will be any shortfalls in interest or principal
to any Class of Certificates that would occur on such Distribution Date without the inclusion of the Gain-on-Sale Remittance Amount
in the definition of “Available Funds” and shall remit all amounts on deposit in the Gain-on-Sale Reserve Account
to the Collection Account to be included as part of the applicable Available Funds. 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 Section 4.01(i), Section 4.01(j) and Section 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 has
provided the Certificate Administrator with written 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 will 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:


 


(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


 






    -307-


     


    

 


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
year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator,
directly or through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender
of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses
of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable
to any Certificateholder on any amount held in trust 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 the Mortgage Loans
shall be distributed to the Holders of the Class Z Certificates from the Excess Interest Distribution Account. Excess Interest
will not be available to pay any other amounts except for distributions on Class Z Certificates as set forth in the prior
sentence.


 






    -308-


     


    

 


(k)            
Each Loan REMIC Regular Interest’s share of all payments made on the related Mortgage Loan (other than any Excess Interest,
Default Interest and amounts distributable to the related Loan REMIC Residual Interest in accordance with the related REMIC Declaration)
shall be deemed to be paid at the time payments are made under the related Mortgage Loan (in the case of interest, at the Mortgage
Rate of such Mortgage Loan) and then deposited in the Lower-Tier REMIC before payments are made to the Trustee as Holder of the
Lower-Tier Regular Interests, and shall be treated as principal, interest and Yield Maintenance Charges, as the case may be, based
on these characterizations with respect to such Mortgage Loan (or related REO Property), except where expressly noted and, in
addition, any payment of principal on or reduction in the Stated Principal Balance of such Mortgage Loan shall reduce the principal
balance of the related Loan REMIC Regular Interest. Any portion of the Aggregate Available Funds attributable to such Mortgage
Loans on deposit in the Collection Account after giving effect to withdrawals of funds pursuant to Section 3.05(a)(i)
through Section 3.05(a)(xiii) shall be distributable to the Class R Certificates in respect of amounts distributed
on the Loan REMIC Residual Interests from the Loan REMIC Residual Distribution Account. Servicing Fees, Trustee Fees and Operating
Advisor Fees with respect to these Mortgage Loans shall be deemed paid by the Lower-Tier REMIC in determining the Net Mortgage
Rate of the related Loan REMIC Regular Interest, and all other servicing compensation or unanticipated expenses with respect to
such Mortgage Loans payable to the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee or the Operating
Advisor shall be deemed payable by the related Loan REMIC.


 


(l)             
On the 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 Serviced Companion Loan in the following order of priority:


 


(i)              
to pay to the Master Servicer 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 the Serviced Whole Loan Remittance Date to the account of


 






    -309-


     


    

 


such Companion Holder or an agent therefor appearing on the Companion Register on the related Record Date (or, if no such account
so appears or information relating thereto is not provided at least five (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 Companion Register). Any
such account shall be located at a commercial bank in the United States.


 


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

Within

at any time during the calendar year was a Holder of a Certificate, a statement containing the information set forth in clauses (i)
and (ii) above as to the applicable Class, aggregated for such calendar year or applicable portion thereof during which
such 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

Upon
receipt of an Asset Review Report Summary from the Asset Representations Reviewer required to be delivered pursuant to Section 12.01(b)

(c)            
Each of the Master Servicer and the Special Servicer may, at its sole cost and expense, make available by electronic media, bulletin
board service or Internet website (in addition to making information available as provided herein) any reports or other information
the Master Servicer or the Special Servicer, as applicable, is required or permitted to provide to any party to this Agreement,
the Rating Agencies or any Certificateholder or any prospective Certificateholder that has provided the Certificate Administrator,
the Master Servicer or the Special Servicer, as applicable, with an Investor Certification or has executed a “click-through”
confidentiality agreement in accordance with Section 3.13 (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 or Special Servicer’s Internet website, the Master Servicer or the Special Servicer, as applicable, shall
take reasonable measures to ensure that only such parties listed above may access such information including, without limitation,
requiring registration, a confidentiality agreement and acceptance of a disclaimer. The Master Servicer or the Special Servicer,
as applicable, is not liable for dissemination of this information in accordance with this Agreement, and neither the Master Servicer
nor the Special Servicer will be responsible for any information delivered, produced, or made available pursuant to Section 3.13
and 4.02(c), other than information produced by the Master Servicer or the Special Servicer, as applicable; provided
that such information otherwise meets the requirements set forth herein with respect to the form and substance of such information
or reports. The Master Servicer may attach to any report provided pursuant to this subsection, any reasonable disclaimer with
respect to information provided, or any assumptions required to be made by such report.


 


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


 


Notwithstanding
the foregoing, the failure of the Master Servicer or the Special Servicer to disclose any information otherwise required to be
disclosed pursuant to this Section 4.02(c) or Section 4.02(d) shall not constitute a breach of this Section 4.02(c)
or of Section 4.02(d) to the extent the Master Servicer or the Special Servicer so fails because such disclosure,
in the reasonable belief of the Master Servicer or the Special Servicer, as the case may be, would violate any applicable law
or any provision of a Mortgage Loan document prohibiting disclosure of information with respect to the Mortgage Loans or the Mortgaged
Properties. The Master Servicer or the Special Servicer may affix to any information provided by it any disclaimer


 






    -314-


     


    

 


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


 


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


 


(f)             
Upon the reasonable request of the Directing 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
on account of it constituting Excluded Information, 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 may conclusively rely on delivery from the Directing


 






    -315-


     


    

 


Certificateholder or a Controlling Class Certificateholder, of an Investor Certification substantially in the form of Exhibit
P-1D that such 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 to be made in respect of the related Distribution Date, (ii) apply amounts held
in the Collection Account, for future distribution to Certificateholders in subsequent months in discharge of any such obligation
to make P&I Advances or (iii) make P&I Advances in the form of any combination of (i) and (ii) aggregating the total
amount of P&I Advances to be made. Any amounts held in the Collection Account for future distribution and so used to make
P&I Advances with respect to the Mortgage Loans shall be appropriately reflected in the Master Servicer’s records and
replaced by the Master Servicer by deposit in the Collection Account on or before the next succeeding P&I Advance Date (to
the extent not previously replaced through the deposit of Late Collections of the delinquent principal and/or interest in respect
of which P&I Advances were made). The Master Servicer shall notify the Certificate Administrator of (i) the aggregate
amount of P&I Advances with respect to the Mortgage Loans and any REO Mortgage Loans for a Distribution Date and (ii) the
amount of any Nonrecoverable P&I Advances with respect to the Mortgage Loans and any REO Mortgage Loans for such Distribution
Date. If the Master Servicer fails to make a required P&I Advance by 4:00 p.m., New York City time, on any P&I Advance
Date, the Trustee shall make such P&I Advance pursuant to Section 7.05 by noon, New York City time, on the related
Distribution Date, unless the Master Servicer has 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. If the Master Servicer fails
to make a required P&I Advance hereunder, the Certificate Administrator shall notify the Trustee of such circumstances by
4:30 p.m., New York City time, on the related P&I Advance Date. Notwithstanding the foregoing, the portion of any P&I
Advance equal to the CREFC® Intellectual Property Royalty License Fee for the related Mortgage Loans and any REO
Mortgage Loans shall not be remitted to the Certificate Administrator for deposit into the Lower-Tier REMIC Distribution Account
but shall be deposited into the Collection Account for payment to CREFC® on such Distribution Date.


 


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


 






    -316-


     


    

 








(including any REO Mortgage Loan as to which the related Balloon Payment
would have been past due), an amount equal to the Assumed Scheduled Payment (net of any collections of previously unadvanced principal
and interest (adjusted to the related Net Mortgage Rate) received with respect to such Mortgage Loan or REO Mortgage Loan, as
applicable, during the related Collection Period) therefor. Subject to subsection (c) below, the obligation of the
Master Servicer to make such P&I Advances is mandatory, and with respect to any Mortgage Loan (including any Non-Serviced
Mortgage Loan) or REO Mortgage Loan, shall continue until the Distribution Date on which the proceeds, if any, received in connection
with a Liquidation Event or the disposition of the REO Property, as the case may be, with respect thereto are to be distributed.
Neither the Master Servicer nor the Trustee shall make or be permitted to make any P&I Advances with respect to any Companion
Loan. The Special Servicer shall not make any P&I Advances on any Mortgage Loan or Companion Loan.


 


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


 


(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


 






    -317-


     


    

 


Collection Account (but in no event from any funds allocable to a Serviced Companion Noteholder
(unless related thereto), except to the extent permitted pursuant to the terms of the related Intercreditor Agreement), interest
at the Reimbursement Rate in effect from time to time, accrued on the amount of such P&I Advance from the date made to but
not including the date of reimbursement; provided, however, that no interest will accrue on any P&I Advance
(i) made with respect to a Mortgage Loan until after the related Due Date has passed and any applicable Grace Period has
expired or (ii) if the related Periodic Payment is received after the Determination Date but on or prior to the related P&I
Advance Date. The Master Servicer shall reimburse itself and/or the Trustee, as the case may be, for any outstanding P&I Advance,
subject to Section 3.17, 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, Balloon Payment or any P&I Advance with respect to any
Companion Loan and (ii) if an Appraisal Reduction Amount has been determined to exist with respect to any Mortgage Loan (or,
in the case of a Non-Serviced Whole Loan, an “appraisal reduction amount” (or similar item has been made in accordance
with the related Non-Serviced PSA and the Master Servicer has notice of such appraisal reduction amount), 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.


 


(f)             
In no event shall either the Master Servicer or the Trustee be required to make a P&I Advance with respect to any Companion
Loan or with respect to any cure payment by the holder of any Serviced Subordinate Companion Loan.


 


Section 4.04      
Allocation of Realized Losses. (a)  On each Distribution Date, immediately following the distributions to be
made on such date pursuant to Section 4.01, the Certificate Administrator shall calculate the amount, if any, by which
(i) the aggregate Stated Principal Balance (for purposes of this definition only, not giving effect to any reductions of the Stated
Principal Balance for payments of principal collected on the Mortgage Loans that were used to reimburse any Workout-Delayed Reimbursement
Amounts pursuant to Section 3.05(a)(v) to the extent such Workout-Delayed Reimbursement Amounts are not otherwise
determined to be Nonrecoverable Advances) of the Mortgage Loans and any REO Mortgage Loans expected to be outstanding immediately
following such Distribution Date, is less than (ii) the then-aggregate Certificate Balance of the Principal Balance Certificates
after giving effect to distributions of principal on such Distribution Date (any such deficit, the “Realized Loss”).
Any allocation of


 






    -318-


     


    

 


Realized Losses to a Class of Certificates shall be made by reducing the Certificate Balance thereof by the
amount so allocated. The allocation of Realized Losses shall constitute an allocation of losses and other shortfalls experienced
by the Trust. Reimbursement of previously allocated Realized Losses do not constitute distributions of principal for any purpose
and do not result in an additional reduction in the Certificate Balance of the applicable Certificate in respect of which any
such reimbursement is made. With respect to any Certificate (other than any Class X Certificate), 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 and in the case of Realized Losses, in sequential order according to the priority of payments for
such Class of Certificates (other than the Class X Certificates) (and in the case of the Class A-1, Class A-2,
Class A-3 and Class A-SB 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 Balance of any Class of 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 first, to the Class NR-RR Certificates, second,
to the Class G-RR Certificates, third, to the Class F-RR Certificates, fourth, to the Class E Certificates,
fifth, to the Class D Certificates, sixth, to the Class C Certificates, seventh, to the Class B
Certificates, eighth, to the Class A-S Certificates, and then, pro rata (based on their respective Certificate
Balances), to the Class A-1, Class A-2, Class A-3 and Class A-SB Certificates, in each case until the remaining
Certificate Balances of such Classes of Certificates have been reduced to zero.


 


(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 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 Non-Reduced Certificates
and 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 the respective Classes of Principal Balance Certificates in reverse sequential order to notionally
reduce the related Certificate Balances until the Certificate Balance of each such Class is reduced to zero (i.e.,
first, to the Class NR-RR Certificates, second, to the Class G-RR Certificates, third, to the Class F-RR
Certificates, fourth, to the Class E Certificates, fifth, to the Class D Certificates, sixth, to
the Class C Certificates, seventh, to the Class B Certificates, eighth, to the Class A-S Certificates,
and finally, pro rata based on their respective Certificate Balances, to the Class A-1, Class A-2, Class A-3
and Class A-SB Certificates).


 






    -319-


     


    

 


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 the Master Servicer obtaining knowledge or receiving notice that
a Non-Serviced Mortgage Loan has become an AB Modified Loan, the Master Servicer shall (i) promptly request from the related
Non-Serviced Master Servicer, Non-Serviced Special Servicer and Non-Serviced Trustee the most recent appraisal with respect to
such AB Modified Loan, in addition to all other information reasonably required by the Master Servicer to calculate whether a
Collateral Deficiency Amount exists with respect to such AB Modified Loan, and (ii) as of the first Determination Date following
receipt by the Master Servicer of the appraisal and any other information set forth in the immediately preceding clause (i)
that the Master Servicer reasonably expects to receive, calculate whether a Collateral Deficiency Amount exists with respect
to such AB Modified Loan, taking into account the most recent appraisal obtained by the Non-Serviced Special Servicer with respect
to such Non-Serviced Mortgage Loan, and all other information relevant to a Collateral Deficiency Amount determination. Upon obtaining
knowledge or receipt of notice by any other party to this Agreement that a Non-Serviced Mortgage Loan has become an AB Modified
Loan, such party shall promptly notify the Master Servicer thereof. None of the Master Servicer (with respect to Mortgage Loans
other than any Non-Serviced Mortgage Loan), the Special Servicer (with respect to Non-Serviced Mortgage Loans), the Trustee nor
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 a related Mortgage Loan that is 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 (i.e., first, to the Class NR-RR Certificates,
second, to the Class G-RR Certificates and third, to the Class F-RR Certificates). For the avoidance of
doubt, for purposes of determining the Controlling Class or the occurrence and continuance of a Control Termination Event,
any Class of Control Eligible Certificates shall be allocated both applicable Appraisal Reduction Amounts and applicable Collateral
Deficiency Amounts (the sum of which shall constitute the applicable Cumulative Appraisal Reduction Amount), in accordance with
this Section 4.05(a).


 


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


 


The
Master Servicer or the Special Servicer, in each case with respect to amounts required to be calculated by such party, shall promptly
notify the Master Servicer or Special Servicer, as applicable, and the Certificate Administrator of the amount of any Appraisal
Reduction Amount (which notification to the Certificate Administrator shall be made by delivery of such information included in
the CREFC® Loan Periodic Update File in accordance with


 






    -320-


     


    

 


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


 


(b)           
(i)  The Holders of the majority of Voting Rights of any Class of Control Eligible 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”) if an event has occurred at, or with respect to, the related
Mortgaged Property or Mortgaged Properties that would have a material effect on its appraised value. The Special Servicer shall
use its reasonable best efforts to cause such second Appraisal to be (i) delivered within thirty (30) days from receipt of
the Requesting Holders’ written request and (ii) prepared on an “as-is” basis by an MAI appraiser (provided
that such MAI appraiser may not be the same MAI appraiser that provided the Appraisal in respect of which the Requesting Holders
are requesting the Special Servicer to obtain an additional Appraisal).


 


(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 Appraisal Reduction Amount or Collateral Deficiency Amount (as applicable) is warranted, and if so warranted, the Special
Servicer shall recalculate the Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable, based on such supplemental
appraisal. If required by such recalculation, the Appraised-Out Class shall be reinstated as the Controlling Class and
each other Appraised-Out Class shall, if applicable, have its related Certificate Balance notionally restored to the extent
required by such recalculation of the Appraisal Reduction Amount or Collateral Deficiency Amount, if applicable. In addition,
the Requesting Holders of any Appraised-Out Class shall have the right, at their sole expense, to require the Special Servicer
to order an additional Appraisal of any Mortgage Loan (other than a Non-Serviced Mortgage Loan) for which an Appraisal Reduction
Event has occurred or as to which there exists a Collateral Deficiency Amount if an event has occurred at or with regard to the
related Mortgaged Property or Mortgaged Properties that would have a material effect on its appraised value, and the Special Servicer
shall use its








    -321-


     


    

 


reasonable efforts to obtain such Appraisal from an MAI appraiser reasonably acceptable to the Special Servicer
within thirty (30) days from receipt of the Requesting Holders’ written request; provided that the Special Servicer
is not required to obtain such Appraisal if it determines in accordance with the Servicing Standard that no events at or with
regard to the related Mortgaged Property or Mortgaged Properties have occurred that would have a material effect on the Appraised
Value of the related Mortgaged Property or Mortgaged Properties. The Holders of an Appraised-Out Class requesting any supplemental
Appraisal pursuant to clause (i) above shall refrain from exercising any direction, control, consent and/or similar
rights of the Controlling Class 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 (as applicable) 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, if any.


 


(c)            
With respect to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any Serviced Whole Loan as to which an Appraisal
Reduction Event has occurred (unless such Mortgage Loan or Serviced Whole Loan has remained current for three consecutive Periodic
Payments, and with respect to which no other Appraisal Reduction Event has occurred with respect to that Mortgage Loan during
the preceding three months (for such purposes taking into account any amendment or modification of such Mortgage Loan, any related
Companion Loan or Serviced Whole Loan)), the Special Servicer shall (1) within thirty (30) days of the occurrence or of each
anniversary of the related Appraisal Reduction Event, and (2) upon its determination that the value of the related Mortgaged
Property has materially changed, notify the Master Servicer (and, with respect to a Serviced Whole Loan, the Master Servicer shall,
upon receipt of such notification from the Special Servicer, promptly notify the related Other Master Servicer, Other Special
Servicer and Other Trustee) of the occurrence of such anniversary or determination and order an Appraisal (which may be an update
of a prior Appraisal), the cost of which shall be paid by the Master Servicer as a Servicing Advance or to the extent it would
be a Nonrecoverable Advance, an expense of the Trust, or conduct an internal valuation, as applicable, and promptly following
receipt of any such Appraisal or performance of such valuation (or receipt of any Appraisal obtained in accordance with Section 4.05(b)
above), shall promptly deliver a copy thereof to the Master Servicer, the Certificate Administrator, the Trustee, the Operating
Advisor and ((i) while no Consultation Termination Event is continuing and (ii) other than with respect to any Excluded
Loan with respect to such party) the Directing Holder; provided, however, that no new or updated Appraisal shall
be required if the Mortgage Loan, Serviced Whole Loan or REO Property is under contract to be sold within ninety (90) days of
such Appraisal Reduction Event or anniversary thereof and the Special Servicer reasonably believes such sale is likely to close.
Based upon such Appraisal or internal valuation (or any Appraisal obtained in accordance with Section 4.05(b)) and
receipt of information reasonably requested by the Special Servicer from the Master Servicer necessary to calculate the Appraisal
Reduction Amount that is either in the Master Servicer’s possession or reasonably obtainable by the Master Servicer, the
Special Servicer shall determine or redetermine, as applicable, and report to the Master Servicer, the Certificate Administrator,
the Trustee, the Operating Advisor and ((i) while no Consultation Termination


 






    -322-


     


    

 


Event is continuing and (ii) other than
with respect to an Excluded Loan with respect to such party) the Directing Holder, the amount and calculation or recalculation
of the Appraisal Reduction Amount or Collateral Deficiency Amount with respect to such Mortgage Loan, Companion Loan or Serviced
Whole Loan, as applicable, and such report shall be delivered in the CREFC® Appraisal Reduction Amount Template
format; provided, however, that the Special Servicer is not liable for failure to comply with such duties insofar
as such failure results from a failure of the Master Servicer to provide sufficient information to the Special Servicer to comply
with such duties or failure by the Master Servicer to otherwise comply with its obligations hereunder. Such report shall also
be forwarded by the Master Servicer (or the Special Servicer if the related Mortgage Loan is a Specially Serviced Loan), to the
extent the related Serviced Companion Loan has been included in an Other Securitization, to the Other Servicer, to the extent
required by the related Intercreditor Agreement, of such Other Securitization into which the related Serviced Companion Loan has
been sold, or to the holder of any related Serviced Companion Loan by the Master Servicer (or the Special Servicer if the 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. If no Consultation Termination Event is continuing (and other than with respect to
an Excluded Loan as to such party), the Special Servicer shall consult with the Directing Holder with respect to any Appraisal,
valuation or downward adjustment in connection with an Appraisal Reduction Amount or Collateral Deficiency Amount. Notwithstanding
the foregoing but subject to Section 4.05(b), the Special Servicer is not required to obtain an Appraisal or conduct
an internal valuation, as applicable, with respect to a Mortgage Loan or related Companion Loan or Serviced Whole Loan as to which
an Appraisal Reduction Event has occurred to the extent the Special Servicer has obtained an Appraisal or conducted such a valuation
(in accordance with requirements of this Agreement), as applicable, with respect to the related Mortgaged Property within the
six-month period immediately prior to the occurrence of such Appraisal Reduction Event. Instead, the Special Servicer may use
such prior Appraisal or valuation, as applicable, in calculating any Appraisal Reduction Amount or Collateral Deficiency Amount
with respect to such Mortgage Loan or related Companion Loan or Serviced Whole Loan; provided that the Special Servicer
is not aware of any material change to the related Mortgaged Property having occurred and affecting the validity of such Appraisal
or valuation.


 


The
Master Servicer shall deliver by electronic mail to the Special Servicer any information in its possession reasonably required
to determine, calculate, redetermine or recalculate any Appraisal Reduction Amount, using reasonable efforts to deliver such information,
within four (4) Business Days following the Special Servicer’s reasonable request therefor (which request shall be made
promptly, but in no event later than ten (10) Business Days, after the Special Servicer’s receipt of the applicable Appraisal
or preparation of the applicable internal valuation); provided that the Special Servicer’s failure to timely make
such request shall not relieve the Master Servicer of its obligation to use reasonable efforts to provide such information to
the Special Servicer within four (4) Business Days following the Special Servicer’s reasonable request.


 


(d)           
Any Mortgage Loan (other than any Non-Serviced Mortgage Loan), any related Serviced Companion Loan and any Serviced Whole Loan
previously subject to an Appraisal Reduction Amount, which has become a Corrected Loan (for such purposes taking into


 






    -323-


     


    

 


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


 


(e)            
Each Serviced Whole Loan will be treated as a single Mortgage Loan for purposes of calculating an Appraisal Reduction Amount with
respect to the Mortgage Loan and Companion Loan(s) that comprise such Serviced Whole Loan. Any Appraisal Reduction Amount in respect
of a Serviced AB Whole Loan will be allocated in accordance with the related Intercreditor Agreement or, if no allocation is specified
in the related Intercreditor Agreement, then, first, to the related Subordinate Companion Loan(s) (until its principal balance
is notionally reduced to zero by such Appraisal Reduction Amounts) and then, pro rata, to the related Mortgage Loan and
any related Pari Passu Companion Loan(s). Any Appraisal Reduction Amount in respect of any Serviced Pari Passu Whole Loan will
be allocated in accordance with the related Intercreditor Agreement or, if no allocation is specified in the related Intercreditor
Agreement, then, pro rata, between the related Serviced Pari Passu Mortgage Loan and the related Serviced Pari Passu Companion
Loan(s), based upon their respective outstanding principal balances.


 


Section 4.06      
Grantor Trust Reporting. (a) The parties intend that the portion of the Trust Fund constituting the Grantor Trust
shall constitute, and that the affairs of the Grantor Trust shall be conducted so as to qualify such portion as, a “grantor
trust” under subpart E, part I of subchapter J of the Code, and the provisions hereof shall be interpreted consistently
with this intention. In furtherance of such intention, neither the Trustee nor the Certificate Administrator shall vary the investment
of the Holders of the Class Z Certificates in the Grantor Trust so as to improve their rate of return. The Certificate Administrator
shall prepare or cause to be prepared, submit to the Trustee for execution (and the Trustee shall timely execute and timely return
to the Certificate Administrator) and timely file all Tax Returns in respect of the Grantor Trust. In addition, the Certificate
Administrator shall (A) file, or cause to be filed, Internal Revenue Service Form 1041, Form 1099 or such other
form as may be applicable with the Internal Revenue Service with copies of the statements in the following clause and (B) furnish,
or cause to be furnished, to the Holders of the Class Z Certificates, their allocable share of income and expense with respect
to 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 received notice that the Class Z Certificates are held through a “middleman” as defined
in the WHFIT Regulations, then the Grantor Trust is a WHFIT that is a WHMT. The Certificate Administrator will report as required
under the WHFIT Regulations to the extent such information as is reasonably necessary to enable the Certificate Administrator
to do so is provided to the Certificate Administrator on a timely basis. The Certificate Administrator is hereby directed to assume
that DTC and Hare & Co. are the only “middlemen” as defined by the WHFIT Regulations unless the Depositor provides
the Certificate Administrator with the identities of the other “middlemen” that are Certificateholders. The Certificate
Administrator shall be entitled to indemnification in accordance with the terms of this Agreement if the Internal Revenue Service
makes a determination that the first sentence of this paragraph is incorrect.


 






    -324-


     


    

 


(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 is not responsible or liable for providing
subsequently amended, revised or updated information to any Certificateholder, unless requested by the Certificateholder.


 


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


 


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


 


Section 4.07      
Investor Q&A Forum; Investor Registry; and Rating Agency Q&A Forum and Document Request Tool. (a)  The
Certificate Administrator shall make available, only to Privileged Persons, the Investor Q&A Forum. The “Investor
Q&A Forum” shall be a service available on the Certificate Administrator’s Website, where (i) Certificateholders
and beneficial owners of Certificates that are Privileged Persons may submit questions to (A) the Certificate Administrator

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 Advisor, 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: AskMidland@Midlandls.com), in each case within a commercially reasonable period of time following

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 is not 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 any
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 is not 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 Holder 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 if 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, (vi) that answering any 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, 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

certify to any of the information posted in the Investor Q&A Forum and no such party will have any responsibility or liability
for the content of any such information. The Certificate Administrator is not 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

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 e-mail 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 is not 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.

Q&A Forum and Document Request Tool. Any reports posted by the 17g-5 Information Provider in response to an inquiry may be

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 the Special Servicer, as applicable, under this Agreement, it is not required
to answer such Rating Agency Inquiry and shall promptly notify the 17g-5 Information Provider by e-mail 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 will not be liable for the failure by
any other such Person to so answer. Questions posted on the Rating Agency Q&A Forum and Document Request Tool shall not be

Section 4.08      
Secure Data Room. (a) The Certificate Administrator shall create a Secure Data Room within 120 days following the Closing
Date. The Depositor shall upon the receipt of each Mortgage Loan Seller’s Diligence File Certificate, deliver to the Certificate
Administrator within 120 days following the Closing Date, 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 received by it to the Secure Data Room. Access to the Secure Data
Room shall be granted by the Certificate Administrator to (i) the Asset Representations Reviewer and (ii) provided that
the Certificate Administrator has received the Diligence File Certificate from each Mortgage Loan Seller pursuant to Section 2.01(h),
any other Person at the direction of the Depositor, in each case, upon the occurrence of an Affirmative Asset Review Vote and
receipt by the Certificate Administrator of a certification substantially in the form of Exhibit RR (which shall be sent
via e-mail to trustadministrationgroup@wellsfargo.com


 






    -328-


     


    

 


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. If 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 will 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 is not required to restrict access to the Secure Data Room on a loan-by-loan basis and
any Person with access to the Secure Data Room shall covenant to access only the information necessary to perform its duties and
responsibilities under this Agreement.


 


(c)            
Upon the resignation or removal of the Certificate Administrator pursuant to Section 8.07, the Certificate Administrator
shall transfer electronic copies of the Diligence Files to a successor certificate administrator designated in writing by the
Depositor or the Master Servicer, and all costs and expenses associated with the transfer of the Diligence Files shall be payable
as part of the costs and expenses associated with the transfer of its responsibilities upon the resignation or removal of the
Certificate Administrator pursuant to Section 8.07. Following the date on which any Mortgage Loan is paid in full,
liquidated, repurchased or otherwise removed from the Trust, the Master Servicer or the Special Servicer, as applicable, may direct
the Certificate Administrator in writing to delete the Diligence File related to such Mortgage Loan from the Secure Data Room;
provided that absent such direction, the Certificate Administrator is not required 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 is the Certificate Administrator obligated
to reproduce or retrieve such deleted files.

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

with the Certificate Registrar, at its principal trust office, as custodian, for the Depository, and registered in the name of

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 appointed the initial 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

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

(other than the Retained Certificates) to the respective beneficial owners or owners. For the avoidance of doubt, the Class R
and Class Z Certificates and the Retained Certificates shall only be in the form of Definitive Certificates (in the case

(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 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.

after the date hereof, the Certificate Administrator may establish any number of subaccounts to the Retained Horizontal Interest
Safekeeping Account for the HRR Retaining Party or to the Retained Vertical Interest Safekeeping Account for the VRR Retaining
Party. The Retained Certificates to be delivered in physical form to the Certificate Administrator shall be delivered as set forth

but shall be remitted directly to the applicable Retaining Party in accordance with written instructions (which shall be in the
form of Exhibit XX to this Agreement) provided separately by such Retaining Party to the Certificate Administrator. Under
no circumstances by virtue of safekeeping the Retained Certificates shall the Certificate Administrator (i) be obligated to bring
legal action or institute proceedings against any person on behalf of a Holder of Retained Certificates or (ii) have any obligation
to monitor, supervise or enforce the performance of any party under the Credit Risk Retention Compliance Agreement. The Certificate
Administrator shall be entitled to conclusively rely with no obligation to verify, confirm or otherwise monitor the accuracy of
any information included in any written instructions provided in connection with a Retained Interest Safekeeping Account and shall
have no liability in connection therewith, other than with respect to the Certificate Administrator’s obligation to obtain
the Depositor’s and the Retaining Sponsor’s consent prior to any release of the Retained Certificates. The Certificate
Administrator shall hold the Definitive Certificates representing the Retained Certificates at the below location, or any other
location; provided the Certificate Administrator has given notice to the Retaining Parties of such new location:

by delivering to the Depository for credit to the respective accounts of such holders, a duly executed and authenticated Regulation S

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

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 (if the applicable
Book-Entry Certificate is the Temporary Regulation S Book-Entry Certificate), in the form of Exhibit N (if the
applicable Book-Entry Certificate is the Regulation S Book-Entry Certificate) or in the form of Exhibit O (if
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,

    -337-


     


    

 


(which may be by e-mail 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 Section 5.02(e), 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 Retained Certificates. During the Transfer Restriction Period, if a Transfer of all or a portion of the Retained
Certificates is to be made, then the Certificate Administrator shall facilitate such transfer in conjunction with the Certificate
Registrar and shall refuse to register such transfer unless it receives (and, upon receipt, may conclusively rely upon) each of
the following, sent to the address provided in Section 13.05: (A) a letter from the Retaining Party instructing
the Certificate Administrator of its intention to release the related Retained Certificates from the applicable Retained Certificate
Safekeeping Account and to transfer such Retained Certificates, (B) a certification from such Certificateholder’s prospective
Transferee substantially in the form of Exhibit D-3 or Exhibit D-5, as applicable, which such certification
must be countersigned by the Retaining Sponsor, (C) a certification from the Certificateholder desiring to effect such transfer
substantially in the form of Exhibit D-4 or Exhibit D-6, as applicable, which such certification must be countersigned
by the Retaining Sponsor and the Depositor (who shall sign promptly upon request of the Retaining Sponsor), (D) a W-9 completed
by the Transferee and (E) wire instructions and contact information of the Transferee. Upon receipt of the foregoing certifications,
the Certificate Registrar shall, subject to Section 5.02(e) and Section 5.03(a), reflect all or any such
portion of the Retained Certificates in the name of the prospective Transferee. For the avoidance of doubt, in no event shall
a Retained Certificate be held as a Book-Entry Certificate during the Transfer Restriction Period. Any attempted or purported
transfer in violation of this Section 5.03(i) shall be null and void ab initio and shall vest no rights in
any purported transferee and shall not relieve the Transferor of any obligations with respect to the applicable Certificates.


 


(j)             
Other Exchanges. If a Book-Entry Certificate is exchanged for a Definitive Certificate, such Certificates may be exchanged
only in accordance with such procedures as are substantially consistent with the provisions of subsections (c) through
(f) above (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) of any such Certificate shall be made unless the Trustee and Certificate Administrator has received
a representation letter from the proposed purchaser or Transferee of such Certificate substantially in the form of Exhibit F-1,
to the effect that such proposed purchaser or Transferee is not and will not become (A) an employee benefit plan subject to the
fiduciary responsibility or prohibited transaction 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) or other plan subject to any federal, state or local law (“Similar Law”)
which is, to a material extent, similar to Section 406 of ERISA or Section 4975 of the Code (each, a “Plan”)

plan assets within the meaning of U.S. Department of Labor Reg. Section 2510.3-101, as modified by Section 3(42) of ERISA), other
than an insurance company purchasing and holding such Certificates with the assets of its general account under circumstances
that meet all the requirements under Sections I and III of Prohibited Transaction Class Exemption 95-60 (or, in the case of a
Plan subject to Similar Law, where the purchase, holding and disposition of such Certificate will not constitute or result in
a non-exempt violation of Similar Law). 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.


 


In
addition, each beneficial owner of a Certificate or any interest therein that is a Plan subject to Title I of ERISA or Section
4975 of the Code (an “ERISA Plan”) or is acting on behalf of or using the assets of an ERISA Plan, shall be
deemed to have represented and warranted that (i) none of the Depositor, the Sponsors, the Underwriters, the Initial Purchasers,
the Trustee, the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator, the Asset Representations
Reviewer or any of their respective affiliated entities, has provided any investment advice within the meaning of Section 3(21)
of ERISA (and applicable regulations) to the ERISA Plan or the fiduciary making the investment decision for the ERISA Plan in
connection with the ERISA Plan’s acquisition of Certificates, and (ii) the ERISA Plan fiduciary making the decision to acquire
the Certificates is exercising its own independent judgment in evaluating the investment in the Certificates.

Plan or using the assets of a Plan (including any entity whose underlying
assets include plan assets within the meaning of U.S. Department of Labor Reg. Section  2510.3-101, as modified by Section
3(42) of ERISA) to purchase such Class R or Class Z Certificate. Each prospective Transferee of a Class R or Class Z
Certificate shall deliver to the Transferor and the Certificate Administrator a representation letter, substantially in the form
of Exhibit F-2, stating that the prospective Transferee is not a Plan or a person acting on behalf of or using the
assets of a Plan. 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.


 


(p)           
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 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


 






    -340-


     


    

 


or is acting as an agent (including a broker, nominee or other middleman) for a
Person that is not a Permitted Transferee, and (6) the proposed Transferee expressly agrees to be bound by and to abide by
the provisions of this Section 5.03(o) and (y) other than in connection with the initial issuance of a Class R
Certificate, require a statement from the proposed Transferor substantially in the form attached as Exhibit D-2 (the
“Transferor Letter”), that the proposed Transferor has no actual knowledge that the proposed Transferee is
not a Permitted Transferee and has no actual knowledge or reason to know that the proposed Transferee’s statements in its
Transferee Affidavit are false.


 


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


 


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


 


(r)            
[Reserved].


 


(s)            
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 is not required for
such withholding, and the Certificateholders shall be required to provide the Certificate Administrator with such forms and other
such information reasonably required by the Certificate Administrator. If the Certificate Administrator does withhold any amount
from interest or original issue discount payments or advances thereof to any Certificateholder or payee pursuant to federal withholding
requirements, the Certificate Administrator shall indicate the amount withheld to such Person. Such amounts shall be deemed to
have been distributed to such Persons for all purposes of this Agreement.

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 expenses of the Certificate Registrar) connected therewith. Any replacement Certificate

    -352-


     


    

 


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)           
The Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer each may
be merged or consolidated with or into any Person, or transfer all or substantially all of its assets (which may be limited to

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

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 Companion Loan Rating Agency

as part of the trust in a related Other Securitization, is subject to the reporting requirements of the Exchange Act, if the Master
Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer notifies the Depositor in writing
(a “Merger Notice”) of any such merger, consolidation, conversion or other change in form, and the Depositor
or the depositor in such Other Securitization, as the case may be, notifies the Master Servicer, the Special Servicer, the Operating
Advisor or the Asset Representations Reviewer, 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, has 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,

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, has
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

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,

(including in its capacity as Custodian) shall be liable for special, punitive, indirect or consequential loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Trustee or the Certificate Administrator has been advised
of the likelihood of such loss or damage and regardless of the form of action. Each of the Master Servicer (including in its capacity
as Companion Paying Agent), 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

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

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 the case of any Serviced Whole Loan, the rights 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 such Serviced Companion Loan);
provided, however, that if a Serviced Whole Loan and/or the holder of any related Companion Loan are involved, such
expenses, costs and liabilities will be payable out of funds related to the applicable Serviced Whole Loan in accordance with
the related Intercreditor Agreement and will also be payable out of the other funds in the Collection Account if amounts on deposit
with respect to such Serviced Whole Loan are insufficient therefor. If any such expenses, costs or liabilities relate to a Mortgage
Loan or Companion Loan, then any subsequent recovery on that Mortgage Loan or Companion Loan, as applicable, will be used to reimburse
the Trust for any amounts advanced for the payment of such expenses, costs or liabilities. In such event, the legal expenses and
costs of such action, proceeding, hearing or examination and any liability resulting therefrom shall be expenses, costs and liabilities
of the Trust, and the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer,
the Asset Representations Reviewer and the Operating Advisor shall be entitled to be reimbursed therefor out of amounts attributable

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

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),

fees and expenses (including costs of enforcement of this indemnity) that any of them may sustain arising from or as a result
of any willful misconduct, bad faith or negligence of the 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) 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

The applicable Non-Serviced Master Servicer, Non-Serviced Special Servicer, Non-Serviced Paying Agent, Non-Serviced Operating
Advisor, Non-Serviced Depositor, Non-Serviced Certificate Administrator and Non-Serviced Trustee, and any of their respective

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 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).

Servicer or the Special Servicer will become effective until the Certificate Administrator has filed any required Form 8-K pursuant

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, may appoint any successor master
servicer or special servicer with respect to this Section 6.05; provided that, such successor master servicer

respect to the procedures and timing for such consultation set forth in this Section 6.08(a).


 


If

any action constituting a Major Decision), other than with respect to an Excluded Loan, as to which the Directing Holder has objected
in writing within ten (10) days (or in the case of a determination of an Acceptable Insurance Default, twenty (20) days) after
receipt of the written recommendation and analysis from the Special Servicer (provided that if such written objection has
not been received by the Special Servicer within such ten (10) day (or twenty (20) day) period, then such Directing Holder shall
be deemed to have approved such action); provided that the foregoing consent rights of the Directing Holder will not apply
to any applicable Excluded Loan; and (i) prior to taking any of the following actions with respect to a Specially Serviced Loan,
an REO Loan or an REO Property and (ii) during the continuance of a Consultation Termination Event, with respect to any Mortgage

provided,
however, that notwithstanding the foregoing, the Master Servicer and Special Servicer may mutually agree, as contemplated
by Section 3.18(a), that the Master Servicer will process and obtain the prior consent of the Special Servicer with
respect to any Major Decision or Special Servicer Decision with respect to any Non-Specially Serviced Loan (which consent shall
be deemed received by the Master Servicer if the Special Servicer does not respond within ten (10) days (or twenty (20) days,
in the case of an Acceptable Insurance Default) of delivery to the Special Servicer of the Master Servicer’s written recommendation
and analysis, and all information in the Master Servicer’s possession that is reasonably requested by the Special Servicer
in order to grant or withhold such consent, plus the time period provided to any Serviced Companion Loan Holder under any related
Intercreditor Agreement to consent to a Major Decision); provided that, the Master Servicer shall, without the need for
any such mutual agreement between the Master Servicer and the Special Servicer, process any Major Decision described in subclauses
(i) and (ii) of clause (xiii) of this definition of “Major Decision” with respect to any Non-Specially
Serviced Loan; provided, further, that, if the Special Servicer or Master Servicer (if the Master Servicer is otherwise
authorized by this Agreement to take such action), as applicable, determines that immediate action, with respect to a Major Decision
or Special Servicer Decision, or (i) any other matter requiring consent of the Directing Holder with respect to any Mortgage
Loan other than an Excluded Loan and only if no Control Termination Event is continuing, or (ii) any matter requiring consultation
with the Directing Holder, 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, as the case may be)), such servicer may take any such action without waiting for the Directing Holder’s
response (or without waiting to consult with the Directing Holder, the Risk Retention Consultation Party or the Operating Advisor,
as the case may be), provided that such servicer shall provide the Directing Holder (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; provided, however, that the Special Servicer is not required to obtain the consent of the
Directing Certificateholder for any Major Decision during a Control Termination Event. In addition, other than with respect to
an Excluded Loan as to such party, if no Control Termination Event is continuing, the Directing Holder, 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 Holder may deem advisable or as to which provision is otherwise
made herein.


 






    -364-


     


    

 


If
a Control Termination Event has occurred and is continuing, but for so long as no Consultation Termination Event has occurred
and is continuing, the Special Servicer shall consult with the Directing Holder in connection with any Major Decision not relating
to any Non-Serviced Mortgage Loan or Excluded Loan (and any other actions which otherwise require consultation with the Directing
Holder prior to a Consultation Termination Event hereunder) and consider alternative actions recommended by the Directing Holder
in respect thereof. Additionally, upon request, the Special Servicer shall consult with the Risk Retention Consultation Party
(if no Consultation Termination Event is continuing, only with respect to Specially Serviced Loan) and consider alternative actions
recommended by the Risk Retention Consultation Party in respect thereof. If the Special Servicer receives no response from the
Directing Holder or the Risk Retention Consultation Party within 10 days following its written request for input on any required
consultation, the Special Servicer is not required to consult with the Directing Holder or the Risk Retention Consultation Party,
respectively, on the specific matter; provided, however, that the failure of the Directing Holder or the Risk Retention
Consultation Party to respond shall not relieve the Special Servicer from consulting with the Directing Holder or the Risk Retention
Consultation Party, as applicable, on any future matters with respect to the related Mortgage Loan (other than a Non-Serviced
Mortgage Loan or any applicable Excluded Loan as to such party) or Serviced Whole Loan.


 


Notwithstanding
anything herein to the contrary, no such advice, direction or objection by, from or on the part of the Directing Holder, Operating
Advisor or Risk Retention Consultation Party contemplated in this Section 6.08(a), may require or cause the Master
Servicer or Special Servicer to violate any provision of any Mortgage Loan or related Intercreditor Agreement, applicable law,
this Agreement, or the REMIC Provisions (and, with respect to a Serviced Whole Loan, subject to the rights of the holders of the
related Companion Loan) including without limitation the obligation of the Master Servicer and the Special Servicer to act in
accordance with the Servicing Standard, expose the Trust or any party to this Agreement to liability, materially expand the scope
of its responsibilities hereunder or constitute an action or inaction that, in its reasonable judgment, is not in the best interests
of the Certificateholders.


 


With
respect to (i) if no Consultation Termination Event is continuing, any Major Decision relating to a Specially Serviced Loan, and
(ii) during a Consultation Termination Event, 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 Holder 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, during a Control Termination Event, the Risk Retention Consultation Party shall
be entitled to all information delivered or made available to the Operating Advisor (except with respect to information relating
to an Excluded Loan as to the Risk Retention Consultation Party).


 


If
the Special Servicer or the Master Servicer, as applicable, determines that a refusal to consent by the Directing Holder or any
advice from the Operating Advisor, the Directing Holder or the Risk Retention Consultation Party, would cause the Special Servicer
or Master


 






    -365-


     


    

 


Servicer, as applicable, to violate the terms of any Mortgage Loan, applicable law or this Agreement, including without
limitation, the Servicing Standard, the Special Servicer or the Master Servicer, as applicable, shall disregard such refusal to
consent or advise and notify the Operating Advisor, the Directing Holder 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 Holder and the Operating Advisor 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.


 


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








    -366-


     


    

 


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


 


(b)           
Notwithstanding anything to the contrary contained herein (i) during a Control Termination Event (and at any time with respect
to any Excluded Loan as to such party), the Directing Holder will have no right to consent to or direct any action taken or not
taken by any party to this Agreement; (ii) during a Control Termination Event while no Consultation Termination Event is
continuing, the Directing Holder and the Risk Retention Consultation Party shall remain entitled to receive any notices, reports
or information to which it is entitled pursuant to this Agreement, and the Special Servicer and any other applicable party shall
consult with the Directing Holder and, with respect to any Specially Serviced Loan, the Risk Retention Consultation Party (in
each case, other than with respect to any Excluded Loan as to such party) to the extent set forth herein in connection with any
action to be taken or refrained from taking; and (iii) during a Consultation Termination Event, the Directing Holder (at
any time with respect to any Excluded Loan as to such party) will have no direction, consultation or consent rights hereunder
and no right to receive any notices, reports or information (other than notices, reports or information required to be delivered
to all Certificateholders) or any other rights as Directing Holder.


 


For
the avoidance of doubt, with respect to any Specially Serviced Loan, the Risk Retention Consultation Party shall at all times
remain entitled to receive any notices, reports or information to which it is entitled pursuant to this Agreement, and the Special
Servicer and any other applicable party shall consult on a non-binding basis with the Risk Retention Consultation Party (other
than with respect to any Excluded Loan as to such party) to the extent set forth herein in connection with any action to be taken
or refrained from taking.

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


 


In
addition, if an Operating Advisor Consultation Event has occurred and is continuing, the Special Servicer shall also consult with
the Operating Advisor in connection with any proposed Major Decision as to which it has delivered to the Operating Advisor a Major
Decision Reporting Package (and any other actions which otherwise require consultation with the Operating Advisor) and consider
alternative actions recommended by the Operating Advisor, in respect thereof, provided that such consultation is on a non-binding
basis. If the Special Servicer receives no response from the Operating Advisor within ten (10) days following the later of (i) its
written request for input (which request is required to include the related Major Decision Reporting Package) on any required
consultation and (ii) delivery of all such additional information reasonably requested by the Operating Advisor that is in
the possession of the Special Servicer related to the subject matter of such consultation, the Special Servicer is not required
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 Holder (other than a Non-Serviced Mortgage
Loan) (regardless of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer shall
consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed Major
Decisions that it is processing and consider alternative actions recommended by the Operating Advisor, in respect thereof, in
accordance with the procedures set forth in this Section 6.08 for consulting with the Operating Advisor.


 


In
connection with the Directing Holder’s or Operating Advisor’s right to consent or consult with respect to a Major
Decision, as applicable, if the Special Servicer determines that action is necessary to protect the related Mortgaged Property
or the interests of the Certificateholders from potential harm if such action is not taken, or if a failure to take any such action
at such time would be inconsistent with the Servicing Standard, the Special Servicer may take actions with respect to the related
Mortgaged Property before the expiration of the applicable


 






    -368-


     


    

 


period for the Operating Advisor or Directing Holder to respond as
described in this Section 6.08, if the Special Servicer reasonably determines in accordance with the Servicing Standard
that failure to take such actions before the expiration of such period would materially adversely affect the interest of the Certificateholders,
and the Special Servicer has made a reasonable effort to contact the Operating Advisor or the Directing Holder, as applicable.


 


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


 


Section 6.09      
Knowledge of Wells Fargo Bank, National Association. Except as otherwise expressly set forth in this Agreement, Wells Fargo
Bank, National Association acting in any particular capacity hereunder shall not be deemed to be imputed with knowledge of (a) Wells
Fargo Bank, National Association, acting in a capacity that is unrelated to the transactions contemplated by this Agreement, or
(b) Wells Fargo Bank, National Association, acting in any other capacity hereunder, except, in the case of either clause (a)
or clause (b), where some or all of the obligations performed in such capacities are performed by one or more
employees within the same group or division of Wells Fargo Bank, National Association, or where the groups or divisions responsible
for performing the obligations in such capacities have one or more of the same Responsible Officers or Servicing Officers, as
applicable; provided that the knowledge of employees performing special servicing functions shall not be imputed to employees
performing master servicing functions and vice versa.

be extended an additional sixty (60) days; provided that the Master Servicer, or the Special Servicer, as applicable, has

(viii)              
either of KBRA or Moody’s (or, in the case of Serviced Pari Passu Companion Loan Securities, any Companion Loan Rating Agency)
has (A) qualified, downgraded or withdrawn its rating or ratings of one or more Classes of Certificates or Serviced Pari
Passu Companion Loan Securities, as applicable, or (B) placed one or more Classes of Certificates or Serviced Pari Passu

(and such qualification, downgrade, withdrawal or “watch status” placement shall not have been withdrawn by KBRA or

(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”) is 


 






    -371-


     


    

 


continuing, then, and
in each and every such case, so long as such Servicer Termination Event shall not have been remedied, the Trustee or the Depositor
may, and at the written direction of ((i) for so long as no Control Termination Event is continuing and (ii) other than
with respect to any Excluded Loan) the Directing Holder (solely with respect to the Special Servicer) 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 applicable, upon five (5) Business Days’ written notice if there
is a Servicer Termination Event under clause (iii)(A) 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, 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) or (a)(ix), the Master Servicer will have a forty-five (45) day period after such
notice in which to find a successor master


 






    -372-


     


    

 


servicer qualified to act as Master Servicer hereunder in accordance with Section 6.05
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 Master Servicer hereunder. If 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. Any appointment of a master servicer in accordance with this paragraph shall be subject to the receipt of Rating Agency
Confirmation and Companion Loan Rating Agency Confirmations with respect to any Serviced Companion Loan Securities.


 


Notwithstanding
Section 7.01(b), if any Servicer Termination Event on the part of the Special Servicer is continuing that (a) affects
a Serviced Pari Passu Companion Loan, any related Serviced Pari Passu Companion Loan Holder or the rating on any class of Serviced
Companion Loan Securities and the Special Servicer is not otherwise terminated or (b) affects only a Serviced Pari Passu Companion
Loan, any related Serviced Pari Passu Companion Loan Holder or the rating on any class of Serviced Companion Loan Securities,
the Holder of such Serviced Pari Passu Companion Loan or the Other Trustee appointed under the related Other Pooling and Servicing
Agreement, as applicable, to the extent permitted under the applicable Intercreditor Agreement, may 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 such 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 Companion
Loan Rating Agency Confirmations with respect to any Serviced Companion Loan Securities.


 


(d)           
Subject to the right of the Operating Advisor to recommend the termination of the Special Servicer and recommend a Qualified Replacement
Special Servicer and the right of the applicable Certificateholders to approve the replacement of the Special Servicer with such
Qualified Replacement Special Servicer pursuant to this Section 7.01(d), and subject to the rights of the holder of
a related Subordinate Companion Loan pursuant to the related Intercreditor Agreement, at any time no Control Termination Event
is continuing and other than with respect to any Excluded Loan with respect to the Directing Holder or the Holder of the majority
of the Controlling Class, the Directing Holder may terminate the rights (subject to Section 3.11 and Section 6.04)
and obligations of the Special Servicer under this Agreement, with or without cause, upon ten (10) Business Days’ notice
to the Special Servicer, the Master Servicer, the Certificate Administrator, the Trustee and the Operating Advisor; such termination
to be effective upon the appointment of a successor special servicer meeting the requirements of this Section 7.01(d),
provided that, with respect to a Servicing Shift Whole Loan, the ten (10) Business Days’ notice set forth in this
Section 7.01(d) shall not apply to the related Directing Holder’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 Holder (other than with respect
to any


 






    -373-


     


    

 


Excluded Loan with respect to the Directing Holder, or, if the Directing Holder is the Directing Certificateholder, the
Holder of the majority of the Controlling Class) shall designate a successor special servicer; provided, however,
that (i) such successor will meet the requirements set forth in Section 7.02, (ii) each Rating Agency delivers
Rating Agency Confirmation and Companion Loan Rating Agency Confirmations with respect to any Serviced Companion Loan Securities
and (iii) no replacement of the Special Servicer shall be effective until the Certificate Administrator has 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.


 


During
a Control Termination Event, 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, (b) payment by such Holders to the Certificate
Administrator of the reasonable fees and expenses (including any legal fees and any Rating Agency fees and expenses) to be incurred
by the Certificate Administrator in connection with administering such vote and which shall not be additional expenses of the
Trust and (c) delivery by such Holders to the Certificate Administrator and Trustee of Rating Agency Confirmation and Companion
Loan Rating Agency Confirmations with respect to any Serviced Companion Loan Securities (which Rating Agency Confirmation and
Companion Loan Rating Agency Confirmations shall be obtained at the expense of such Holders), the Certificate Administrator shall
promptly post notice to all Certificateholders of such request on the Certificate Administrator’s Website in accordance
with Section 3.13(b) and concurrently by mail, and conduct the solicitation of votes of all Certificates in such regard,
which vote shall occur within one hundred eighty (180) days of the posting of such notice. Upon the written direction of (a) Holders
of Principal Balance Certificates evidencing at least 66-2/3% of a Certificateholder Quorum or (b) Holders of Non-Reduced Certificates
evidencing more than 50% of the aggregate Voting Rights of each Class of Non-Reduced Certificates, the Trustee shall terminate
all of the rights and obligations of such Special Servicer under this Agreement and appoint the successor special servicer (which
must be a Qualified Replacement Special Servicer) designated by such Certificateholders.


 


The
Certificate Administrator shall include on each Distribution Date Statement a statement that each Certificateholder may (i) access
such notices via the Certificate Administrator’s Website and (ii) register to receive electronic mail notifications
when such notices are posted thereon. Notwithstanding the foregoing, the Certificateholders’ direction to replace the Special
Servicer will not apply to a Serviced AB Whole Loan unless, with respect to a Serviced AB Whole Loan, an Control Appraisal Period
has occurred.


 


The
parties hereto acknowledge that, notwithstanding anything to the contrary contained in this Section 7.01(d), in accordance
with the related Intercreditor Agreement, if a servicer termination event on the part of a Non-Serviced Special Servicer under
a Non-Serviced PSA remains unremedied and affects the holder of the related Non-Serviced Mortgage Loan, and the related Non-Serviced
Special Servicer has not otherwise been terminated, the holder of the related Non-Serviced Mortgage Loan (or the Trustee (or,
prior to a Control Termination Event, the Trustee, acting at the direction of the Directing Certificateholder)) will be entitled
to direct the related Non-Serviced Trustee to terminate the related Non-Serviced Special Servicer solely with


 






    -374-


     


    

 


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


 


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








    -375-


     


    

 


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


 


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


 


For
the avoidance of doubt, the indemnification of the Operating Advisor in Section 6.04 shall include, subject to the
limitations set forth in Section 6.04, any action or claim arising from, or relating to, the Operating Advisor’s
determination under this Section 7.01(d) (regarding removal of the Special Servicer), or the result of the vote of
the 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.
In no event shall the remedy for a breach of the foregoing covenant extend beyond termination pursuant to Section 7.01(a)(viii)
and Section 7.01(a)(ix) and the resulting operation of Section 7.01(b) and (c). The operation
of this subsection (e) shall not be construed to limit the effect of Section 7.01(a)(viii) and Section 7.01(a)(ix).


 


(f)             
Notwithstanding the foregoing, (1) if any Servicer Termination Event on the part of the Master Servicer affects a Serviced Companion
Loan, any related Serviced Companion Noteholder or the rating on any class of Serviced Companion Loan Securities, and if the Master
Servicer is not otherwise terminated, or (2) if a Servicer Termination Event on the part of the Master Servicer affects only a
Serviced Companion Loan, any related Serviced Companion Noteholder or the rating on any class of certificates backed, wholly or
partially, by any Serviced Companion Loan Securities, then the Master Servicer may not be terminated by or at the direction of
such Serviced Companion Noteholder or the holders of any certificates backed, wholly or partially, by such Serviced Companion
Loan, but upon the written direction of such Serviced Companion Noteholder, the Master Servicer shall 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. If no Control
Termination Event is continuing, if the applicable Excluded Special Servicer Loan is not also an Excluded Loan as to such party,
the Directing Holder 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. During a Control Termination Event or if the Directing Certificateholder
or the majority Controlling Class Certificateholder on its behalf fails to make the selection contemplated by the prior sentence
within ten (10) Business Days or if at any time the applicable Excluded


 






    -376-


     


    

 


Special Servicer Loan is also an Excluded Loan as to the
Directing Holder, the resigning Special Servicer shall use reasonable efforts to select the related Excluded Special Servicer.
The Special Servicer shall not have any liability with respect to the actions or inactions of the applicable Excluded Special
Servicer or with respect to the identity of the applicable Excluded Special Servicer. It shall be a condition to any such appointment
that (i) the Rating Agencies confirm that the appointment would not result in a qualification, downgrade or withdrawal of
any of their then-current ratings of the Certificates and each NRSRO hired to provide ratings with respect to any Serviced Companion
Loan Securities makes the equivalent confirmation, (ii) the related Excluded Special Servicer is a Qualified Replacement
Special Servicer and (iii) the related Excluded Special Servicer delivers to the Depositor and the Certificate Administrator
and any applicable Other Depositor and Other Certificate Administrator, the information, if any, required under Item 6.02
of Form 8-K pursuant to the Exchange Act regarding itself in its role as Excluded Special Servicer.


 


If
at any time the Special Servicer is no longer a Borrower Party (including, without limitation, as a result of the related Mortgaged
Property becoming an REO Property) with respect to an Excluded Special Servicer Loan, (1) the related Excluded Special Servicer
shall resign, (2) the related Mortgage Loan or Serviced Whole Loan shall no longer be an Excluded Special Servicer Loan,
(3) the Special Servicer shall become the Special Servicer again for such related Mortgage Loan or Serviced Whole Loan and
(4) the Special Servicer shall be entitled to all special servicing compensation with respect to such Mortgage Loan or Serviced
Whole Loan earned during such time on and after such Mortgage Loan or Serviced Whole Loan is no longer an Excluded Special Servicer
Loan.


 


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


 


If
a Servicing Officer of the Master Servicer, a related Excluded Special Servicer, or the Special Servicer, as applicable, has actual
knowledge that a Mortgage Loan is no longer an Excluded Loan, an Excluded Controlling Class Loan or an Excluded Special Servicer
Loan, as applicable, the Master Servicer, the related Excluded Special Servicer or the Special Servicer, as applicable, shall
provide prompt written notice thereof to each of the other parties to this Agreement.


 


Section 7.02      
Trustee to Act; Appointment of Successor. On and after the time the Master Servicer or the Special Servicer, as the case
may be, either resigns pursuant to subsection (a) of the first sentence of Section 6.05 or receives a
notice of termination for cause pursuant to Section 7.01(b), and provided that no acceptable successor has
been appointed within the time period specified in Section 7.01(c), the Trustee shall be the successor to such party,
until such successor to the Master Servicer or the Special Servicer, as applicable, is appointed as provided in this Section 7.02
or by the Directing Holder as provided in Section 7.01(d), as applicable, in all respects in its capacity as the
Master Servicer or the Special Servicer, as






    -377-


     


    

 


applicable, under this Agreement and the transactions set forth or provided for herein
and shall be subject to, and have the benefit of, all of the rights, (subject to Section 3.11 and Section 6.04)
benefits, responsibilities, duties, liabilities and limitations on liability relating thereto and that arise thereafter placed
on or for the benefit of the Master Servicer or the Special Servicer, as applicable, by the terms and provisions hereof; provided,
however, that any failure to perform such duties or responsibilities caused by the terminated party’s failure under
Section 7.01 to provide information or moneys required hereunder shall not be considered a default by such successor
hereunder. The appointment of a successor master servicer shall not affect any liability of the predecessor Master Servicer which
may have arisen prior to its termination as Master Servicer, and the appointment of a successor special servicer shall not affect
any liability of the predecessor Special Servicer which may have arisen prior to its termination as Special Servicer. The Trustee
in its capacity as successor to the Master Servicer or the Special Servicer, as the case may be, is not 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 and the Companion Loans that the Master Servicer would have
been entitled to if the Master Servicer had continued to act hereunder, including but not limited to any income or other benefit
from any Permitted Investment pursuant to Section 3.06, and subject to Section 3.11, and the Trustee as
successor to the Special Servicer shall be entitled to the Special Servicing Fees to which the Special Servicer would have been
entitled if the Special Servicer had continued to act hereunder. Should the Trustee succeed to the capacity of the Master Servicer
or the Special Servicer, as the case may be, the Trustee shall be afforded the same standard of care and liability as the Master
Servicer or the Special Servicer, as applicable, hereunder notwithstanding anything in Section 8.01 to the contrary,
but only with respect to actions taken by it in its role as successor master servicer or successor special servicer, as the case
may be, and not with respect to its role as Trustee hereunder. Notwithstanding the above, the Trustee may, if it shall be unwilling
to act as successor to the Master Servicer or the Special Servicer, as applicable, or shall, if it is unable to so act, or if
the Trustee is not approved as a servicer by each Rating Agency, or if the Directing Holder (solely with respect to the Special
Servicer) ((i) if no Control Termination Event is continuing and (ii) other than with respect to any Excluded Loan as
to such party) or the Holders of Certificates entitled to a majority 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
or other entity which meets the criteria set forth in Section 6.05 and otherwise herein, as the successor to the Master
Servicer or the Special Servicer, as applicable, hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of the Master Servicer or the Special Servicer hereunder. No appointment of a successor to the Master Servicer
or the Special Servicer hereunder shall be effective until (i) the assumption in writing by the successor to the Master Servicer
or the Special Servicer of all its responsibilities, duties and liabilities hereunder that arise thereafter, (ii) upon receipt
of Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency Confirmations with respect to any Serviced
Companion Loan Securities, (iii) which appointment has been approved (if no Control Termination Event is continuing) by the
Directing Holder, such approval not to be unreasonably


 






    -378-


     


    

 


withheld and (iv) the Certificate Administrator has 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 Master Servicer or the Special Servicer (whichever is not the terminated party)
and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.
Any costs and expenses associated with the transfer of the servicing function (other than with respect to a termination without
cause) under this Agreement shall be borne by the predecessor Master Servicer or Special Servicer, as applicable. If such predecessor
Master Servicer or Special Servicer (as the case may be) has not reimbursed the party requesting such termination or the successor
master servicer or special servicer for such expenses within ninety (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 will 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 Special Servicer in accordance with this Agreement at the direction of any party or parties
permitted to direct the Trustee to so terminate the Master Servicer or the Special Servicer pursuant to this Agreement, the Trustee
shall not have any liability for such expenses pursuant to this paragraph.


 


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


 


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


 






    -379-


     


    

 


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


 


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

prior to the occurrence of a Servicer Termination Event and after the curing or waiving of all Servicer Termination Events which

Servicer Termination Event 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 exercise as a prudent person would exercise or use under the circumstances

terms of Article II), shall examine them to determine whether they conform to the requirements of this Agreement. If any
such instrument is found not to conform to the requirements 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 is not responsible for the accuracy or content of any resolution, certificate, statement, opinion, report, document,

that:


 


(i)              
Prior to the occurrence of a Servicer Termination Event, and after the curing of all such Servicer Termination Events which may
have occurred, the duties and obligations of the Trustee and the Certificate Administrator shall be determined solely by the express
provisions of this Agreement, the Trustee and the Certificate Administrator will not be liable except for the performance of 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

the Certificate Administrator and conforming to the requirements of this Agreement;


 


(ii)              
Neither the Trustee nor the Certificate Administrator, as applicable, will be liable for an error of judgment made in good faith

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% of the Percentage Interest of each affected Class, or 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

Certain Matters Affecting the Trustee and the Certificate Administrator. Except as otherwise provided in Section 8.01:


 


(i)

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 have offered to the Trustee or the Certificate Administrator,
as applicable, reasonable security or indemnity satisfactory to it, against the costs, expenses and liabilities which may be incurred
therein or thereby; neither the Trustee nor the Certificate Administrator shall be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights
or powers, if it has reasonable grounds for believing that repayment of such funds or reasonable indemnity satisfactory to it
against such risk or liability is not reasonably assured to it; nothing contained herein shall, however, relieve the Trustee of
the obligation, upon the occurrence of a Servicer Termination Event which has not been cured, to exercise


 






    -382-


     


    

 


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

Neither the Trustee nor the Certificate Administrator shall be liable for any action reasonably taken, suffered or omitted by

(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 reasonable indemnity satisfactory to it from such requesting Holders against such expense or liability as a condition
to taking any such action. The reasonable expense of every such reasonable examination shall be paid by the requesting Holders;


 


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


 


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

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

be entitled to the same rights, indemnities, immunities, privileges and protections afforded to the Trustee hereunder in the same
manner as if such party were the named Trustee herein.


 


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 
2.02 and 2.04 and the signature, if any, of the Certificate Registrar and Authenticating Agent set forth on any outstanding
Certificate, shall be taken as the statements of the Depositor, the Master Servicer or the Special Servicer, as the case may be,
and the Trustee or the Certificate Administrator assume no responsibility for their correctness. Neither the Trustee nor the Certificate
Administrator makes any representations as to the validity or sufficiency of this Agreement (other than as to this Agreement being
a valid obligation of the Trustee and the Certificate Administrator) or of any Certificate (other than as to the signature, if
any, of the Trustee or the Certificate Administrator set forth thereon) or of any Mortgage Loan or 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 are not 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.

    -384-


     


    




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 its duties hereunder, the Trustee shall be paid its portion of the Certificate
Administrator/Trustee Fee, which shall cover recurring and otherwise reasonably anticipated expenses of the Trustee. As compensation
for the performance of its duties hereunder, the Certificate Administrator shall be paid its portion of the Certificate Administrator/Trustee
Fee, which shall cover recurring and otherwise reasonably anticipated expenses of the Certificate Administrator. The Certificate
Administrator shall pay the Trustee the Trustee’s portion of the Certificate Administrator/Trustee Fee. The Certificate
Administrator/Trustee Fee shall be paid monthly on a Mortgage Loan-by-Mortgage Loan basis. As to each Mortgage Loan and REO
Mortgage Loan, the Certificate Administrator shall pay to the Trustee monthly the Trustee fee from the Certificate Administrator/Trustee
Fee, which Certificate Administrator/Trustee Fee shall accrue from time to time at the Certificate Administrator/Trustee Fee
Rate and the Certificate Administrator/Trustee Fee shall be computed on the basis of the Stated Principal Balance of such
Mortgage Loan, as applicable, and a 360-day year consisting of twelve 30-day months. The Certificate Administrator/Trustee
Fee (which shall not be limited to any provision of law in regard to the compensation of a trustee of an express trust) shall
constitute the Trustee’s and the Certificate Administrator’s sole form of compensation for all services rendered
by them in the execution of the trusts hereby created and in the exercise and performance of any of the powers and duties
of the Trustee and Certificate Administrator hereunder, except for the reimbursement of expenses specifically provided for
herein. The Certificate Administrator/Trustee Fee shall not be payable with respect to any related 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, representative or agent of the Trustee and the Certificate Administrator, respectively, shall
be indemnified and held harmless by the Trust (to the extent of amounts on deposit in the Collection Account or the Lower-Tier

as applicable, reasonable control) to timely publish any report to be delivered, published or otherwise made available by the
Certificate Administrator pursuant to Section 4.02 and such failure shall continue unremedied for a period of five
(5) days, or if the Certificate Administrator fails to make distributions required pursuant to Section 4.01 or Section 9.01,
then the Depositor may remove the Trustee or Certificate Administrator, as applicable, and appoint a successor trustee or certificate
administrator, by written instrument, in duplicate, which instrument shall be delivered to the Trustee or Certificate Administrator
so removed and to the successor trustee or certificate administrator in the case of the removal of the Trustee or Certificate
Administrator. A copy of such instrument shall be delivered to the Master Servicer, the Special Servicer and the Certificateholders
by the Depositor. Except as described in the following sentence, the terminated or removed Trustee or Certificate Administrator,

so removed and one complete set to the successor so appointed. A copy of such instrument shall be delivered to the Depositor,
the Special Servicer and the remaining Certificateholders by the Master Servicer. In the event of any such termination without
cause pursuant to this Section 8.07(c), the successor trustee or certificate administrator, as applicable, shall be

(d)           
Any resignation or removal of the Trustee or Certificate Administrator and appointment of a successor trustee or certificate administrator

by the successor trustee or certificate administrator as provided in Section 8.08 and (ii) the Certificate Administrator
has 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.

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

was not assigned to the outgoing trustee, the Custodian shall, upon its receipt of a Request for Release, deliver such Mortgage

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

    -390-


     


    

 


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 is continuing, the Trustee alone will have the power to make such appointment. No co-trustee or separate trustee hereunder
will be required to meet the terms of eligibility as a successor trustee under Section 8.06 and no notice to Holders
of Certificates of the appointment of co-trustee(s) or separate trustee(s) will be required under Section 8.08. All

duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by
the Trustee and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in which
any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer or the Special
Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights,
powers, duties and obligations (including the holding of title to the Trust or any portion thereof in any such jurisdiction) shall
be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee.


 


(c)            
Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then-separate trustees
and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall
refer to this Agreement and the conditions of this Article VIII. Each separate trustee and co-trustee, upon its acceptance
of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly
with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including
every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee.
Every such instrument shall be filed with the Trustee.


 


(d)           
Any separate trustee or co-trustee may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full power and
authority, to the extent not prohibited by law, to 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.

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


 






    -391-


     


    

 


Custodian meeting the foregoing
requirements. The appointment of one or more Custodians by the Certificate Administrator shall not relieve the Certificate Administrator
from any of its obligations hereunder, and the Certificate Administrator shall remain responsible for all acts and omissions of
any Custodian. Any Custodian appointed hereunder must maintain a fidelity bond and errors and omissions policy in an amount customary
for Custodians which serve in such capacity in commercial mortgage loan securitization transactions, or may self-insure.

SB,
Class X-A, Class X-B, Class X-D, Class A-S, Class B, Class C, Class D and Class E Certificates
have been reduced to zero, the voluntary exchange by the Sole Certificateholder of all the outstanding Certificates (other than
the Class Z and Class R Certificates) for the remaining Mortgage Loans and REO Properties in the Trust Fund pursuant
to the terms of the immediately succeeding paragraph; provided, however, that in no event shall the trust created
hereby continue beyond the expiration of twenty-one (21) years from the death of the last survivor of the descendants of Joseph
P. Kennedy, the late ambassador of the United States to the Court of St. James’s, living on the date hereof. Upon termination
of the Trust pursuant to clause (i) of the immediately preceding sentence, the Custodian shall release or cause to be released
to the Master Servicer, at the address provided in Section 13.05 or to such other address designated by the Master
Servicer in writing, any Mortgage Files remaining in its possession. In connection with a termination of the Trust under this
Article IX, the obligations and responsibilities of the Custodian under this Agreement shall terminate upon its delivery
of the Mortgage Files to the Master Servicer, Sole Certificateholder or other party as required by this Section 9.01,
except for the obligation of the Custodian to execute assignments, endorsements and other instruments as required by this Section 9.01.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3,
Class A-SB, Class X-A, Class X-B, Class X-D, Class A-S, Class B, Class C, Class D and
Class E Certificates have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting
in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer if the then-outstanding aggregate Stated Principal Balance of the
Mortgage Loans and each REO Property is greater than or equal to 8.125% of the aggregate principal balance of the Mortgage Loans
as of the Cut-off Date (as provided in the Preliminary Statement), 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 as contemplated
by clause (iii) of the first paragraph of this Section 9.01 by giving written notice to all the parties
hereto no later than sixty (60) days prior to the anticipated date of exchange. If the Sole Certificateholder elects to exchange
all of its Certificates (other than the Class Z and Class R Certificates) for all of the Mortgage Loans and the Trust’s
portion of each REO Property remaining in the Trust in accordance with the preceding sentence, such Sole Certificateholder, not
later than the Distribution Date on which the final distribution on the Certificates is to occur, shall remit for 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 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


 






    -396-


     


    

 


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 each Serviced Loan REMICs and 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, the related
Loan REMIC Regular Interests and Related Lower-Tier Regular Interests.


 


The
obligations and responsibilities under this Agreement of the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Administrator and the Companion Paying Agent shall terminate with respect to any Companion Loan to the extent
(i) its related Serviced Mortgage Loan has been paid in full or is no longer part of the Trust Fund and (ii) no amounts
payable by the related Companion Holder to or for the benefit of the Trust or any party hereto in accordance with the related
Intercreditor Agreement remain due and owing.


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R
Certificates, in that order of priority, may, at their option, elect to purchase all of the Mortgage Loans (and all property acquired
through exercise of remedies in respect of any related Mortgage Loan) 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 Balance of the Mortgage Loans and any REO Mortgage Loans held by the Trust is equal to or less than
1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans (solely for the purposes of this calculation, if a Mortgage Loan
with an Anticipated Repayment Date is still an asset of the Trust and such right is being exercised after its respective Anticipated
Repayment Date, then any such Mortgage Loan will be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage
Loans and from the aggregate Stated Principal Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the
Preliminary Statement. This purchase shall terminate the Trust and retire the then-outstanding Certificates.


 


If
the Master Servicer or the Special Servicer purchases, or the Holders of the majority of the Controlling Class or the Holders
of the Class R Certificates purchase, all of the Mortgage Loans 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 Holders of the majority
of the Controlling Class or the Holders of the Class R Certificates, as applicable, shall deposit in the Lower-Tier
REMIC Distribution Account not later than the P&I Advance Date


 






    -397-


     


    

 


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 (a) the reasonable out-of-pocket expenses of the Master Servicer with respect to such termination (if applicable) and (b) any
other 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 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 Holders 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 Holders of the majority of the Controlling Class or the Holders of the Class R Certificates, as applicable, as shall
be necessary to effectuate transfer of the Mortgage Loans and REO Properties remaining in the Trust Fund.


 


For
purposes of this Section 9.01, the Holders of the majority of the Controlling Class shall have the first option
to terminate the Trust REMICs, 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) if such notice is given in connection with the purchase of all of the Mortgage Loans
and each REO Property remaining in the Trust Fund, not earlier than the 15th day and not later than the 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 Yield Maintenance Charges distributable to the Regular Certificates
pursuant to Section 4.01(c) 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 Regular Certificates so presented, (ii) to Holders of the Class Z Certificates so presented,
any amounts remaining on deposit in the Excess Interest Distribution Account, and (iii) any remaining amount shall be distributed
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 Section 4.01(c). 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).


 


Each
Loan REMIC shall terminate as described above or as otherwise described in the related REMIC Declaration.


 


Section 9.02      
Additional Termination Requirements.   If 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 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)

final Tax Returns pursuant to Treasury Regulations Section 1.860F-1;


 


(ii)

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

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.

such number by other permissible means. The Certificate Administrator shall be responsible for the preparation of the related
IRS Form W-9, if such form is requested. The Trustee shall be entitled to rely on the information contained therein, and is hereby
directed to execute such IRS Form W-9; provided, however, the Certificate Administrator shall also be directed to

(e)            
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 Certificate
Administrator shall be the “partnership representative” (within the meaning of Section 6223 of the Code) of each Trust
REMIC. By their acceptance thereof, the Holders of the largest Percentage Interest of the Class R Certificates hereby agree
to irrevocably appoint the Certificate Administrator as the “partnership representative” for the Trust REMICs.


 


(f)             
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. The Certificate Administrator shall prepare or cause
to be prepared, and file or cause to be filed with the IRS, on behalf of each of the Lower-Tier REMIC and the Upper-Tier REMIC,
an application for a taxpayer identification number for such REMIC on IRS Form SS-4 or obtain such number by other permissible
means.


 


(g)            
The Certificate Administrator shall provide or cause to be provided (i) to any Transferor of a Class R Certificate such
information as is necessary for the application of any tax relating to the transfer of such Class R Certificate to any Person
who is a Disqualified Organization, or in the case of a Transfer to an agent thereof, to such agent, (ii) to the Certificateholders
such information or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original
issue discount and market discount or premium (using the Prepayment Assumption) and (iii) to the Internal Revenue Service,
in respect of each Trust REMIC, Form 8811, within thirty (30) days after the Closing Date.


 


(h)            
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”)


 






    -401-


     


    

 


(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 any Trust REMIC, endanger such status or, unless the Certificate Administrator determines in its sole discretion
to indemnify the Trust against such tax, result in the imposition of such a tax (not including a tax on “net income from
foreclosure property”). The Trustee shall not take or fail to take any action (whether or not authorized hereunder) as to
which the Certificate Administrator has advised it in writing that it has received an Opinion of Counsel to the effect that an
Adverse REMIC Event could occur with respect to such action. The Certificate Administrator may consult with counsel to make such
written advice, and the cost of same shall be borne by the 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.


 


(i)             
If 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(i); provided that with respect to the estimated
amount of tax imposed on any “net income from foreclosure property” pursuant to Section 860G(c) of the Code or
any similar tax imposed by a state or local tax authority, the Special Servicer shall retain in the related REO Account a reserve
for the payment of such taxes in such amounts and at such times as it shall deem appropriate (or as advised by the Certificate
Administrator in writing), and shall remit to the Master Servicer such reserved amounts as the Master Servicer shall request in
order to pay such taxes. Except as provided in the preceding sentence, the Master Servicer shall withdraw from the Collection
Account sufficient funds to pay or provide for the payment of, and to actually pay, such tax as is estimated to be legally owed
by any Trust REMIC (but such authorization shall not prevent the Certificate Administrator from contesting, at the expense of
the Trust (other than as a consequence of a breach of its obligations under this Agreement), any such tax in appropriate proceedings,
and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The Certificate Administrator
is hereby authorized to and shall segregate, into a separate non-interest bearing account, the net income from any “prohibited
transaction” under Section 860F(a) of the Code or the amount of any taxable contribution to any Trust REMIC after the
Startup Day that is subject to tax under Section 860G(d) of the Code and use such income or amount, to the extent necessary,
to pay such prohibited transactions tax. To the extent that any such tax (other than any such tax paid in respect of “net
income from foreclosure property”) is paid to the Internal Revenue Service or applicable state or local tax authorities,
the Certificate Administrator shall retain an equal amount from future amounts otherwise distributable to the Holders of Class R
Certificates (as applicable) and shall distribute such retained amounts, (x) in the case of the Loan REMIC Regular Interests,
to the Lower-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 Loan REMIC Residual Interests in the manner specified in Section 4.01(l),
(y) in the case of the Lower-Tier Regular Interests, to the Upper-Tier REMIC to the extent they are fully reimbursed for
any


 






    -402-


     


    

 


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(d) and (z) in the case of the Upper-Tier REMIC, to the Holders of the
Principal Balance Certificates in the manner specified in Section 4.01(a), 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.


 


(j)             
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.


 


(k)            
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 has received an Opinion of Counsel (at the expense of the party
seeking to make such contribution) to the effect that the inclusion of such assets in such Trust REMIC will not cause an Adverse
REMIC Event to occur.


 


(l)             
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.


 


(m)          
Solely for the purposes of Treasury Regulations Section 1.860G-1(a)(4)(iii), the “latest possible maturity date”
by which (i) the Certificate Balance or Notional Amount of each Class of Regular Certificates representing a “regular
interest” in the Upper-Tier REMIC would be reduced to zero and (ii) the Lower-Tier Principal Amount of each Class of
Lower-Tier Regular Interests representing a “regular interest” in the Lower-Tier REMIC would be reduced to zero is
the date that is the Rated Final Distribution Date. The “latest possible maturity date” for purposes of Code Section 860G(a)(1)
for each Loan REMIC Regular Interest is the date set forth in the related REMIC Declaration (the Maturity Date of the related
Mortgage Loan).


 


(n)            
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

Article XI



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 this Article XI
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


 






    -405-


     


    

 


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 CSAIL 2021-C20 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2021-C20, and any Other
Securitization subject to Regulation AB, 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 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 will 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 is not required to bring any legal action
against such third party in connection with such obligation.


 


Section 11.02   
Succession; Subcontractors. (a)  As a condition to the succession to the Master Servicer and the Special Servicer
or to any Sub-Servicer (but only if such Sub-Servicer is a Servicing Function Participant and a servicer as contemplated by Item 1108(a)(2))
as servicer or sub-servicer under this Agreement by any Person (i) into which the Master Servicer and the Special Servicer
or such Sub-Servicer 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, the person removing and replacing the Master Servicer and the Special Servicer
shall provide to the Depositor, 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, the Other Depositor and the 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 or any Additional
Servicer, as the case may


 






    -406-


     


    

 


be, shall submit such disclosure to the Depositor and the Other Depositor no later than the first Business
Day after 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 (subject to Section 3.26(s)),
the Asset Representations Reviewer and the Certificate Administrator (each of the Master Servicer, the Special Servicer, the Trustee,
the Operating Advisor, the Asset Representations Reviewer and the Certificate Administrator and each Sub-Servicer, for purposes
of this Section 11.02, a “Servicer”) is permitted to utilize one or more Subcontractors to perform
certain of its obligations hereunder. If such Subcontractor will be a Servicing Function Participant, such Servicer shall promptly
upon written request provide to the Depositor or any Mortgage Loan Seller (and any Other Trustee, Other Certificate Administrator
and Other Depositor related to any Other Securitization that includes a related Serviced Companion Loan) a written description
(in form and substance satisfactory to the Depositor, such Mortgage Loan Seller or such Other Trustee, Other Certificate Administrator
or Other Depositor, as applicable) of the role and function of each Subcontractor utilized by such Servicer, specifying (i) the
identity of such Subcontractor and (ii) the elements of the Servicing Criteria that will be addressed in assessments of compliance
provided by each such Subcontractor. As a condition to the utilization by such Servicer of any Subcontractor determined to be
a Servicing Function Participant, such Servicer shall (i) with respect to any such Subcontractor engaged by such Servicer
that is an Initial Sub-Servicer, use commercially reasonable efforts to cause, and (ii) with respect to any other subcontractor
with which it has entered into a servicing relationship, cause such Subcontractor used by such Servicer for the benefit of the
Depositor and the Trustee (and any Other Trustee, Other Certificate Administrator and Other Depositor related to any Other Securitization
that includes a related Serviced Companion Loan) to comply with the provisions of Section 11.10 and Section 11.11
to the same extent as if such Subcontractor were such Servicer. With respect to any Servicing Function Participant engaged
by such Servicer that is an Initial Sub-Servicer, such Servicer shall be responsible for using commercially reasonable efforts
to obtain, and with respect to each other Servicing Function Participant engaged by such Servicer, such Servicer shall obtain
from each such Servicing Function Participant and deliver to the applicable Persons any assessment of compliance report and related
accountant’s attestation required to be delivered by such Subcontractor under Section 11.10 and Section 11.11,
in each case, as and when required to be delivered. For the avoidance of doubt, the Custodian shall not 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


 






    -407-


     


    

 


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 information furnished pursuant to this Section 11.02 shall also be provided to each Other Depositor and each Other
Certificate Administrator (to the extent the information relates to a party that services, specially services or is trustee for
a Serviced Companion Loan) in the same time frame as set forth in this Section 11.02.


 


Section 11.03   
Filing Obligations. (a)  The Master Servicer, the Special Servicer, 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, 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, Analysis and Retrieval (“EDGAR”) system)
such Forms executed by the Depositor.


 


Each
party hereto may 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)           
If 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


 






    -408-


     


    

 


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.
If 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 11.04, 11.05, 11.06, 11.07, 11.08, 11.09, 11.10 and 11.11.
The Certificate Administrator will have no liability for any loss, expense, damage, claim arising out of or with respect to any
failure to properly prepare, arrange for execution and/or timely file any such Form 15, Form 12b-25 or any amendments
to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K, where such failure results from the Certificate Administrator’s
inability or failure to receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for
execution or file such Form 15, Form 12b-25 or any amendments to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K,
not resulting from its own negligence, bad faith or willful misconduct.

Form 10-D and Form ABS-EE Filings. (a)  Within fifteen (15) days after each Distribution Date (subject to
permitted extensions under the Exchange Act), the Certificate Administrator shall prepare and file on behalf of the Trust any

shall file each Form 10-D with a copy of the related Distribution Date Statement attached thereto. Any disclosure in addition
to the Distribution Date Statement that is required to be included on Form 10-D (“Additional Form 10-D Disclosure”)
shall, pursuant to the following paragraph be reported by the parties set forth on Exhibit BB to the Depositor and
the Certificate Administrator and approved by the Depositor, and the Certificate Administrator will have no duty or liability
for any failure hereunder to determine or prepare any Additional Form 10-D Disclosure, absent such reporting, direction and
approval.


 


For

five (5) calendar days after the related Distribution Date, (i) certain parties to this Agreement identified on Exhibit BB
shall be required to provide to the Certificate Administrator and the Depositor (and in the case of any Servicing Function

as the case may be, has actual knowledge, in EDGAR-Compatible Format, or in such other format as otherwise agreed upon by the
Certificate Administrator, the Depositor and such providing parties, the form and substance of any Additional Form 10-D Disclosure,

to monitor or enforce the performance by the parties listed on Exhibit BB of their duties under this paragraph or
proactively solicit or procure from such parties any Additional Form 10-D Disclosure information. The Depositor will be responsible
for any reasonable expenses incurred by the Trustee or Certificate Administrator in connection with including any Additional Form 10-D

The
Certificate Administrator shall include in any Form 10-D filed by it (i) the information required by Rule 15Ga-1(a)

consisting of the preceding calendar year or portion thereof and of such Certifying Servicer’s performance under this Agreement,

Certifying Servicer has fulfilled all its obligations under this Agreement, or the applicable sub-servicing agreement or primary
servicing agreement in the case of an Additional Servicer, in all material respects throughout such reporting period, or, if there
has been a failure to fulfill any such obligation in any material respect, specifying each such failure known to such officer
and the nature and status thereof. Such Officer’s Certificate shall be provided in EDGAR-Compatible Format, or in such other
format agreed upon by the Depositor, the Certificate Administrator and such providing parties. Each Certifying Servicer shall

into a servicing relationship with respect to the Mortgage Loans in the fulfillment of any of the Certifying Servicer’s
or Additional Servicer’s obligations hereunder or under the applicable sub-servicing or primary servicing agreement. The
obligations of the Certifying Servicer and each Additional Servicer under this Section 11.09 apply to the Certifying
Servicer and each Additional Servicer that serviced a Mortgage Loan during the applicable period, whether or not such Certifying
Servicer or Additional Servicer is acting as the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator
or Additional Servicer at the time such Officer’s Certificate is required to be delivered. None of the Master Servicer,
Special Servicer or Additional Servicer shall be required to cause the delivery of any such statement until April 15 in any
given year if 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.

the Certificate Administrator, the Master Servicer and the Special Servicer shall, and the Master Servicer and the Special Servicer
shall use commercially reasonable efforts to cause any sub-servicer appointed with respect to any Serviced Pari Passu Companion

to the related Intercreditor Agreement), reasonably cooperate with the Mortgage Loan Seller (or such permitted transferee) selling
any Serviced Pari Passu Companion Loan into a securitization that is required to comply with Regulation AB (a “Regulation
AB Companion Loan Securitization”) and, to the extent needed in order to comply with Regulation AB, provide to the Mortgage
Loan Seller (or such


 






    -428-


     


    

 


permitted transferee) information about itself that such Mortgage Loan Seller reasonably requires to meet
the requirements of Items 1117 and 1119 and paragraphs (b), (c)(3), (c)(4) and (c)(5) of Item 1108 of Regulation AB and shall
reasonably cooperate with such Mortgage Loan Seller to provide such other information as may be reasonably necessary to comply
with the requirements of Regulation AB. Each of the Trustee, the Certificate Administrator, the Master Servicer and the Special
Servicer understands that such information may be included in the offering material related to a Regulation AB Companion Loan
Securitization and agrees to negotiate in good faith an agreement (subject to the final sentence of this sub-section) to indemnify
and hold the related depositor and underwriters involved in the offering of the related Certificates harmless for any costs, liabilities,
fees and expenses incurred by the depositor or such underwriters as a result of any material misstatements or omissions or alleged
material misstatements or omissions in any such offering material to the extent that such material misstatement or omission was

(where such information pertains to the Certificate Administrator individually and not to any specific aspect of the Certificate
Administrator’s duties or obligations under this Agreement), the Master Servicer (where such information pertains to the
Master Servicer individually and not to any specific aspect of the Master Servicer’s duties or obligations under this Agreement)

as applicable, for inclusion in the offering materials related to such Regulation AB Companion Loan Securitization is substantially
and materially similar to the information provided by such party with respect to the offering materials related to this transaction,
subject to any required changes due to any amendments to Regulation AB or any changes in the interpretation of Regulation AB,
such party shall be deemed to be in compliance with this Section 11.16(a). Any indemnification agreement executed
by the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer in connection with the Regulation AB
Companion Loan Securitization shall be substantially similar to the related indemnification agreement executed in connection with
this Agreement. It shall be a condition precedent to any party’s obligations otherwise set forth above that the applicable
Mortgage Loan Seller (or permitted transferee) must have (a) provided reasonable advance notice (and, in any event, not less
than ten (10) Business Days) of the exercise of its rights hereunder and (b) paid, or entered into reasonable agreement to
cause to be paid, the reasonable out-of-pocket expenses (including reasonable fees and expenses of counsel) incurred by such party
in reviewing and/or causing the delivery of any disclosure, opinion of counsel or indemnification agreement.


 


(b)           
Each of the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer shall, and the Master Servicer
and the Special Servicer shall use commercially reasonable efforts to cause any Servicing Function Participant appointed with
respect to a Serviced Securitized Companion Loan to, upon request or notice from such parties (which request or notice may be
given once at the closing of such Regulation AB Companion Loan Securitization instead of each time a filing is required), cooperate
with the depositor, trustee, certificate administrator, master servicer or special servicer for any Regulation AB Companion Loan
Securitization in preparing each Form 10-D, Form ABS-EE and Form 10-K required to be filed by such Regulation

Loan Securitization files a Form 15 Suspension Notification with respect to the related trust) and shall provide to such depositor,
trustee, certificate administrator or master servicer within the time period set forth in the Other Pooling and Servicing Agreement
(so long as such time period is no earlier than the time periods set forth herein) for such Regulation AB Companion Loan Securitization
such information relating to a Serviced Securitized Companion Loan as may be reasonably necessary for the depositor, trustee,
certificate administrator and master servicer of the Regulation AB Companion Loan Securitization to comply with the reporting

Loan Securitization shall consult with the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer
(and Master Servicer shall consult with any sub-servicer appointed with respect to the related Serviced Whole Loan), and the Trustee,
the Certificate Administrator, such Master Servicer and the Special Servicer shall cooperate with such parties in respect of establishing
the time periods for preparation of the Form 10-D and Form ABS-EE reports in the documentation for such Regulation AB Companion
Loan Securitization. Notwithstanding the foregoing, to the extent the Trustee, the Certificate Administrator, the Master Servicer
or the Special Servicer, as the case may be, complies in all material respects with the timing, reporting and attestation requirements
imposed on such party in Article XI (other than this Section 11.16) with respect to the comparable timing,

respect to a Serviced Securitized Companion Loan to, upon request or notice from such trustee or certificate administrator (which
request or notice may be given once at the closing of such Regulation AB Companion Loan Securitization instead of each time a
filing is required), provide the trustee or certificate administrator, as applicable, under a Regulation AB Companion Loan Securitization
(until January 30 of the first year in which the trustee or certificate administrator, as applicable, for such Regulation AB Companion
Loan Securitization files a Form 15 Suspension Notification with respect to the related trust) information with respect to any
event that is required to be disclosed under Form 8-K with respect to a Serviced Securitized Companion Loan within two Business
Days after the occurrence of such event of which it has knowledge. Notwithstanding the foregoing, to the extent the Trustee, the
Certificate Administrator, the Master Servicer or the Special Servicer, as the case may be, complies in all material respects
with the timing, reporting and attestation requirements imposed on such party in Article XI (other than this Section 11.16)
with respect to the comparable timing, reporting and attestation requirements contemplated in this Section 11.16(c)
with respect to such Regulation AB Companion Loan Securitization, such party shall be deemed to be in compliance with the provisions
of this Section 11.16(c).


 


(d)           
On or before March 1 of each year (or February 29 if a leap year) during which a Regulation AB Companion Loan Securitization is
required to file an annual report on Form 10-K (and not in respect of any year in which Regulation AB Companion Loan Securitization
is not required to file an annual report on Form 10-K because a Form 15 Suspension Notification with respect to the related trust
was filed), each of the Trustee, the Master Servicer and the Special

Servicer shall, and the Master Servicer and the Special Servicer
shall use commercially reasonable efforts to cause any Servicing Function Participant appointed with respect to a Serviced Securitized
Companion Loan to, upon request or notice from such trustee or certificate administrator (which request or notice may be given
once at the closing of such Regulation AB Companion Loan Securitization instead of each time a filing is required), provide, with
respect to itself, to the trustee or certificate administrator, as applicable, under such Regulation AB Companion Loan Securitization,
to the extent required pursuant to Item 1122 of Regulation AB, (i) a report on an assessment of compliance with the servicing
criteria to the extent required pursuant to Item 1122(a) of Regulation AB, (ii) a registered accounting firm’s attestation
report on such Person’s assessment of compliance with the applicable servicing criteria to the extent required pursuant
to Item 1122(b) of Regulation AB and (iii) such other information as may be required pursuant to Item 1122(c) of Regulation
AB. Notwithstanding the foregoing, to the extent the Master Servicer or the Special Servicer, as the case may be, complies in
all material respects with the timing, reporting and attestation requirements imposed on such party in Article XI
(other than this Section 11.16) with respect to the comparable timing, reporting and attestation requirements contemplated
in this Section 11.16(d) with respect to such Regulation AB Companion Loan Securitization, such party shall be deemed
to be in compliance with the provisions of this Section 11.16(d).


 


(e)            
On or before March 1 of each year during which a Regulation AB Companion Loan Securitization is required to file an annual report
on Form 10-K (and not in respect of any year in which Regulation AB Companion Loan Securitization is not required to file an annual
report on Form 10-K because a Form 15 Suspension Notification with respect to the related trust was filed), each of the Trustee,
the Certificate Administrator, the Master Servicer and the Special Servicer shall, and the Master Servicer and the Special Servicer
shall use commercially reasonable efforts to cause any Servicing Function Participant appointed with respect to a Serviced Securitized
Companion Loan to, to the extent required pursuant to Item 1123 of Regulation AB, deliver, with respect to itself, to the trustee
or certificate administrator under such Regulation AB Companion Loan Securitization, upon request or notice from such trustee
(which request or notice may be given once at the closing of such Regulation AB Companion Loan Securitization instead of each
time a filing is required), under such Regulation AB Companion Loan Securitization a servicer compliance statement signed by an
authorized officer of such Person that satisfies the requirements of Item 1123 of Regulation AB. Notwithstanding the foregoing,
to the extent the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, as the case may be, complies
in all material respects with the timing, reporting and attestation requirements imposed on such party in this Article XI
(other than this Section 11.16) with respect to the comparable timing, reporting and attestation requirements
contemplated in this Section 11.16(e) with respect to such Regulation AB Companion Loan Securitization, such party
shall be deemed to be in compliance with the provisions of this Section 11.16(e).


 


(f)             
Each of the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer shall use commercially reasonable
efforts to cause a Servicing Function Participant to agree (severally but not jointly) to indemnify (such indemnity limited to
each such parties respective failure described below) and hold the related Mortgage Loan Seller (or permitted transferee), depositor,
sponsor(s), trustee, certificate administrator or master servicer under a Regulation AB Companion Loan Securitization harmless
for any costs, liabilities, fees and expenses incurred by such Mortgage Loan Seller, depositor, sponsor(s), trustee, certificate

administrator or master servicer as a result of any failure by the Servicing Function Participant to comply with the reporting
requirements to the extent applicable set forth under Sections 11.16(b), (c), (d) or (e) above.


 


Any
subservicing agreement related to a Serviced Securitized Companion Loan shall contain a provision requiring the related Sub-Servicer
to provide to the Master Servicer or Special Servicer, as applicable, information, reports, statements and certificates with respect
to itself and such Serviced Securitized Companion Loan comparable to any information, reports, statements or certificates required
to be provided by the Master Servicer or Special Servicer pursuant to this Section 11.16, even if such Sub-Servicer
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 Special Servicer, as applicable, no
later than two Business Days prior to the date on which the Master Servicer or Special Servicer, as applicable, is required to
deliver its comparable information, reports, statements or certificates pursuant to this Section 11.16.


 


(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 is in receipt of the updated financial statements
of such “significant obligor” for any calendar quarter (other than the fourth calendar quarter of any calendar year)
from the Mortgagor or Special Servicer, beginning with the first calendar quarter following receipt of such notice from the Other
Depositor, or the updated financial statements of such “significant obligor” for any calendar year, beginning for
the calendar year following such notice from the Other Depositor, as applicable, the Master Servicer 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, such financial statements of the “significant obligor”, together with the net operating income
of such “significant obligor” for the applicable period as calculated by the Master Servicer 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.


 


If
the Master Servicer does not receive such financial information of any such “significant obligor” (identified to it
as such by the Other Depositor in accordance with the preceding paragraph) 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 shall notify the Other
Depositor with respect to such Other Securitization that includes the related Serviced Pari Passu Companion Loan (and shall cause
any related Sub-Servicing Agreement


 






    -432-


     


    

 


entered into after receipt of written notice from the Other Depositor that such Serviced Pari
Passu Companion Loan is a significant obligor to require the related Sub-Servicer to notify such Other Depositor) that it has
not received them. The Master Servicer 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 shall (and shall cause any related Sub-Servicing Agreement entered into after receipt of written notice from the
Other Depositor that such Serviced Pari Passu 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 by 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, that 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. Such financial
information shall be collected (if applicable), prepared and/or calculated by the party responsible for such collection, preparation
and/or calculation set forth in Section 3.12 and delivered as set forth in Section 3.12(b).


 


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 to 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.

period applicable to such party’s obligations under Article XI as provided for in such clause (x)
nor shall any such party be deemed to not be in compliance under this Agreement, during any grace period under this Article XI

Article XII



the asset representations reviewer


 


Section 12.01   
Asset Review.


 


(a)            
On or prior to each Distribution Date, based on either the CREFC® Delinquent Mortgage Loan Status Report or the
CREFC® Loan Periodic Update File 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 written notice to the Asset Representations Reviewer and to all Certificateholders and each
other party to this Agreement. Any notice required to be delivered to the Certificateholders pursuant to this Section 12.01
shall be delivered by the Certificate Administrator by posting such notice on the Certificate Administrator’s Website,
by mailing to their addresses appearing in the Certificate Register and by delivering such notice via the Depository. The Certificate
Administrator shall include in the Form 10-D relating to the distribution period in which the Asset Review Trigger occurred a
description of the events that caused the Asset Review Trigger to occur. On each Distribution Date after providing such notice
to the Certificateholders, the Certificate Administrator, based on information provided to it by the Master Servicer, shall determine
whether (1) any additional Mortgage Loan has become a Delinquent Loan, (2) any Mortgage Loan has ceased to be a Delinquent
Loan and (3) an Asset Review Trigger has ceased to exist, and, if there is an occurrence of any of the events or circumstances
identified in clauses (1), (2) and/or (3), deliver written notice of such information (which may be
via e-mail) in the form of Exhibit SS within two (2) Business Days to the Master Servicer, the Special Servicer, the Operating
Advisor and the Asset Representations Reviewer.


 


If
Certificateholders evidencing not less than 5.0% 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 (such written direction, the “Asset Review Vote Election”), then
the Certificate Administrator shall promptly provide written notice thereof to the Asset Representations Reviewer and to all Certificateholders
and conduct a solicitation of votes of Certificateholders to authorize an Asset Review. Upon the affirmative vote to authorize
an Asset Review of Holders of Certificates evidencing at least a majority of an Asset Review Quorum within 150 days of receipt
of the Asset Review Vote Election (an “Affirmative Asset Review Vote”), the Certificate Administrator shall
promptly provide written notice thereof to all parties to this Agreement, the Underwriters, the Mortgage Loan Sellers, the Directing
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
to the Certificate Administrator a certification in the form of Exhibit RR. Upon receipt of such certification, the Certificate
Administrator shall promptly (and in any case within two (2) Business Days after such receipt) grant the Asset Representations
Reviewer access to the Secure Data Room. If an Affirmative Asset Review Vote has not occurred within such 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 is not required to review any Delinquent Loan unless and until (A) an additional Mortgage
Loan has become a Delinquent Loan after the expiration of such 150-day period, (B) an additional Asset Review Trigger has
occurred as a result or otherwise is in effect, (C) the Certificate Administrator has timely received an Asset Review Vote
Election after the occurrence of the events described in clauses (A) and (B) in this sentence and (D) an
Affirmative Asset Review Vote has occurred within 150 days after the Asset Review Vote Election described in clause (C)
in this sentence. After the occurrence of any Asset Review Vote Election or an Affirmative Asset Review Vote, no 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 may administer any vote in connection with the foregoing through
an agent.


 


(b)           
(i) If an Affirmative Asset Review Vote has occurred, the Certificate Administrator shall promptly provide written notice
thereof to all parties to this Agreement, the Underwriters, Sponsors, the Directing Holder, the Risk Retention Consultation Party
and all other Certificateholders. Upon receipt of an Asset Review Notice, the Custodian (with respect to clauses (1)
through (5) for Non-Specially Serviced Loans), the Master Servicer (with respect to clauses (6) and (7) for
Non-Specially Serviced Loans) and the Special Servicer (with respect to clauses (6) and (7) 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 (except with respect to clause (7)) after receipt of such notice from the Certificate Administrator, provide
the following materials to the Asset Representations Reviewer (collectively, with the Diligence Files, a copy of the Prospectus,
a copy of each related Mortgage Loan Purchase Agreement and a copy of this Agreement posted to the Secure Data Room by the Certificate
Administrator pursuant to Section 4.08, the “Review Materials”):


 


(1)       a
copy of an assignment of the Mortgage in favor of the Trustee, with evidence of recording thereon, for each Delinquent Loan that
is subject to an Asset Review;


 


(2)       a
copy of an assignment of any related assignment of leases (if such item is a document separate from the Mortgage) in favor of
the Trustee, with evidence of recording thereon, related to each Delinquent Loan that is subject to an Asset Review;


 


(3)       a
copy of the assignment of all unrecorded documents relating to each Delinquent Loan that is subject to an Asset Review, if not
already covered pursuant to items (1) or (2) above;


 


(4)       a
copy of all filed copies (bearing evidence of filing) or evidence of filing of any UCC Financing Statements related to each Delinquent
Loan that is subject to an Asset Review;


 


(5)       a
copy of an assignment in favor of the Trustee of any financing statement executed and filed in the relevant jurisdiction related
to each Delinquent Loan that is subject to an Asset Review;


 






    -435-


     


    

 


(6)
       a copy of any notice previously delivered to the applicable Mortgage Loan Seller by
the Master Servicer or the Special Servicer, as applicable, of any alleged defect or breach with respect to any Delinquent Loan;
and


 


(7)       any
other related documents or agreements that are reasonably requested by the Asset Representations Reviewer to be delivered by the
Master Servicer or the Special Servicer, as applicable, in the time frames and as otherwise described below.


 


(ii)              
If, as part of an Asset Review of any Mortgage Loan, the Asset Representations Reviewer determines that it is missing any documents
or agreements that are required to be a part of the Review Materials for such Mortgage Loan or that were entered into or delivered
in connection with the origination or a modification of such Mortgage Loan and, in each case, that are necessary in connection
with its completion of such Asset Review, the Asset Representations Reviewer shall promptly, but in no event later than ten (10)
Business Days after receipt of the Review Materials, notify the Master Servicer (with respect to Non-Specially Serviced Loans)
or the Special Servicer (with respect to Specially Serviced Loans), as applicable, of such missing documents and agreements, and
request that the Master Servicer or the Special Servicer, as applicable, promptly, but in no event later than ten (10) Business
Days after receipt of such notification from the Asset Representations Reviewer, deliver to the Asset Representations Reviewer
such missing documents and agreements 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 this Agreement. If any missing documents or agreements are not provided by the Master Servicer or the Special Servicer,
as applicable, within such ten (10) Business Day period, the Asset Representations Reviewer shall contact the related Mortgage
Loan Seller to request such documents or agreements from the Mortgage Loan Seller. The Mortgage Loan Seller will be required to
deliver such additional documents and agreements only to the extent in the possession of such Mortgage Loan Seller.


 


(iii)              
The Asset Representations Reviewer may, but is under no obligation to, consider and rely upon information furnished to it by a
Person that is not a party to this Agreement or the related Mortgage Loan Seller, and shall do so only if such information can
be independently verified (without unreasonable effort or expense to the Asset Representations Reviewer) and is determined by
the Asset Representations Reviewer in its good faith and sole discretion to be relevant to the Asset Review (any such information,
“Unsolicited Information”) conducted pursuant to this Section 12.01.


 


(iv)              
Upon receipt by the Asset Representations Reviewer of the Asset Review Notice and access to the Review Materials with respect
to a Delinquent Loan, the Asset Representations Reviewer, as an independent contractor, shall commence an Asset Review. The Asset
Representations Reviewer shall perform an Asset Review with respect to each representation and warranty made by the related Mortgage
Loan Seller with respect to such Delinquent Loan in accordance with the Asset Review Standard and the procedures set forth on
Exhibit QQ (each such procedure, a “Test”); provided, however, that the Asset Representations
Reviewer may, but is under no obligation to, modify any Test and/or associated Review Materials described in Exhibit QQ
if, and only to the extent, the Asset


 






    -436-


     


    

 


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 will have the right to change the scope of the Asset Review, and the Asset Representations Reviewer is not
required to review any information other than (x) the Review Materials and (y) if applicable, Unsolicited Information.


 


(vi)              
The Asset Representations Reviewer may, absent manifest error and subject to the Asset Review Standard, (i) assume, without
independent investigation or verification, that the Review Materials are accurate and complete in all material respects and (ii) conclusively
rely on such Review Materials.


 


(vii)              
If the Asset Representations Reviewer determines that the Review Materials are insufficient to complete a Test and such missing
information and documentation is not delivered to the Asset Representations Reviewer (a) by the Master Servicer (with respect
to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) to the extent in the Master
Servicer’s or the Special Servicer’s possession within ten (10) Business Days or (b) by the related Mortgage Loan
Seller upon request the Asset Representations Reviewer shall list such missing information and documents in a preliminary report
setting forth the preliminary results of the application of the Tests and the reasons why such missing information and documents
are necessary to complete a Test and (if the Asset Representations Reviewer has so concluded) that the absence of such information
and documents shall be deemed to be a failure of such Test. The Asset Representations Reviewer shall provide such preliminary
report to the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially
Serviced Loans) and the related Mortgage Loan Seller. If the preliminary report indicates that any of the representations and
warranties fails or is deemed to fail any Test, the related Mortgage Loan Seller will have ninety (90) days (the “Cure/Contest
Period”) to remedy or otherwise refute the failure. Any information and documents provided or explanations given to
support the Mortgage Loan Seller’s claim that the representation and warranty has not failed a Test or that any missing
information or documents in the Review Materials are not required to complete a Test must be promptly delivered by the related
Mortgage Loan Seller to the Asset Representations Reviewer. For the avoidance of doubt, the Asset Representations Reviewer is
not required to prepare a preliminary report if the Asset Representations Reviewer determines that there is no Test failure with
respect to the related Delinquent Loan.


 


(viii)              
The Asset Representations Reviewer shall, within the later of (x) sixty (60) days after the date on which access to the Diligence
Files in the Secure Data Room is made available to the Asset Representations Reviewer by the Certificate Administrator or (y) ten
(10) days after the expiration of the Cure/Contest Period (whichever is later), complete an


 






    -437-


     


    

 


Asset Review with respect to each
Delinquent Loan and deliver (i) a report setting forth the Asset Representations Reviewer’s findings and conclusions
as to whether or not it has determined there is any evidence of a failure of any Test based on the Asset Review and a statement
that the Asset Representations Reviewer’s findings and conclusions set forth in such report were not influenced by any third
party (an “Asset Review Report”) to each party to this Agreement and the related Mortgage Loan Seller (or,
in the case of a Guaranteed Seller, against the related Guarantor in respect of its respective payment guaranty) for each Delinquent
Loan, and (ii) a summary of the Asset Representations Reviewer’s conclusions included in such Asset Review Report in
the form of Exhibit PP (an “Asset Review Report Summary”) to the Trustee and Certificate Administrator.
The period of time by which the Asset Review Report must be completed and delivered may be extended by up to an additional thirty
(30) days, upon written notice to the parties to this Agreement and the related Mortgage Loan Seller, if the Asset Representations
Reviewer determines pursuant to the Asset Review Standard that such additional time is required due to the characteristics of
the Mortgage Loans and/or the Mortgaged Property or Mortgaged Properties. In no event may the Asset Representations Reviewer determine
whether any Test failure constitutes a Material Defect, or whether the Trust should enforce any rights it may have against the
related Mortgage Loan Seller (or, in the case of the Guaranteed Sellers, the payment guarantee obligations of the related Guarantor
pursuant to the related Mortgage Loan Purchase Agreement), which, in each such case, will be the responsibility of the Enforcing
Servicer.


 


(ix)              
In addition, if the Asset Representations Reviewer does not receive any information or documentation that it requested from the
Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans)
or the related Mortgage Loan Seller in sufficient time to allow the Asset Representations Reviewer to complete its Asset Review
and deliver an Asset Review Report, the Asset Representations Reviewer shall prepare the Asset Review Report solely based on the
information received by the Asset Representations Reviewer with respect to the related Delinquent Loan, and the Asset Representations
Reviewer will have no responsibility to independently obtain any such information from any party to this Agreement or otherwise.


 


(x)              
Within forty-five (45) days after receipt of an Asset Review Report with respect to any Mortgage Loan, the Special Servicer shall
determine whether at that time, based on the Servicing Standard, there exists a Material Defect with respect to such Mortgage
Loan. If the Special Servicer determines that a Material Defect exists, the Special Servicer shall enforce the obligations of
the related Mortgage Loan Seller with respect to such Material Defect in accordance with Section 2.03(b).


 


(c)            
The Asset Representations Reviewer and its Affiliates shall keep all information appropriately labeled as “Privileged Information”

Information from
the Asset Representations Reviewer with a notice stating that such information is Privileged Information shall not disclose such

(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 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

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 may enter into an agreement with any agent or subcontractor
providing for indemnification of the Asset Representations Reviewer by such agent or subcontractor, and nothing contained in this
Agreement shall be deemed to limit or modify such indemnification.

The Asset Representations Reviewer may assign its rights and obligations under this Agreement in connection with the sale or transfer
of all or substantially all of its Asset Representations Reviewer portfolio, provided that: (i) the purchaser or transferee

such laws to perform the duties of the asset representations reviewer resulting from a merger, consolidation or succession that
is permitted under this Agreement, (B) executes and delivers to the Trustee and the Certificate Administrator an agreement that
contains an assumption by such person of the due and punctual performance and observance of each covenant and condition to be
performed or observed by the asset representations reviewer under this Agreement from and after the date of such agreement and
(C) is not a Prohibited Party under this Agreement; (ii) the Asset Representations Reviewer shall not be released from its
obligations under this Agreement that arose prior to the effective date of such assignment and delegation; (iii) the rate
at which the Asset Representations Reviewer Asset Review Fee (or any component thereof) is calculated shall not exceed the rate
then in effect and (iv) the resigning Asset Representations Reviewer shall be responsible for the reasonable costs and expenses
of each other party to this Agreement and the Rating Agencies in connection with such transfer. Upon acceptance of such assignment
and delegation, the purchaser or transferee shall provide notice to each party to this Agreement and then will be the successor
asset representations reviewer hereunder.

(f)             
With respect to any Delinquent Loan that is an Non-Serviced Mortgage Loan, to the extent any documents required by the Asset Representations
Reviewer to complete a Test are missing or have not been received from the related Mortgage Loan Seller, the Asset Representations
Reviewer shall request such document(s) from the related Non-Serviced Master Servicer (if such Non-Serviced Mortgage Loan is being
serviced by a Non-Serviced Master Servicer) or the related Non-Serviced Special Servicer (if such non-Serviced Mortgage Loan is
being serviced by a Non-Serviced Special Servicer), the related Non-Serviced Trustee and the related Non-Serviced Certificate
Administrator (and, in each case, such other party as contemplated under the related Non-Serviced PSA or related Intercreditor
Agreement).


 


Section 12.02   
Payment of Asset Representations Reviewer Fees and Expenses; Limitation of Liability.


 


(a)            
The Asset Representations Reviewer shall be paid a fee of $5,000 on the Closing Date. As compensation for the performance of its
routine duties, the Asset Representations Reviewer shall be paid a fee (the “Asset Representations Reviewer Fee”),
payable monthly from amounts received in respect of each Mortgage Loan and any REO Mortgage Loan and shall be equal to the product
of a rate equal to 0.00038% per annum (the “Asset Representations Reviewer Fee Rate”) and the Stated
Principal Balance of the Mortgage Loans and any REO Mortgage Loans and shall be calculated in the same manner as interest is calculated
on such Mortgage Loans and REO 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 (for purposes of this Section 12.02(b), “Subject
Loans”), upon the completion of any Asset Review with respect to an individual Asset Review Trigger, the Asset Representations
Reviewer shall be paid a fee of: (i) $17,500 multiplied by the number of subject loans, plus (ii) $1,750 per Mortgaged
Property relating to the Subject Loans in excess of one Mortgaged Property per Subject Loan, plus (iii) $2,250 per Mortgaged
Property relating to a Subject Loan subject to a ground lease, plus (iv) $1,250 per Mortgaged Property relating to a Subject
Loan subject to a franchise agreement, hotel management agreement or hotel license agreement, subject, in the case of each of
clauses (i) through (iv), to adjustments on the basis of the year-end Consumer Price Index for All Urban Consumers,
or other similar index if the Consumer Price Index for All Urban Consumers is no longer calculated, from the year of the Closing
Date and to the year of the occurrence of the Asset Review (the “Asset Representations Reviewer Asset Review Fee”).
The Asset Representations Reviewer Asset Review Fee with respect to each Delinquent Loan shall be paid by the related Mortgage
Loan Seller within forty-five (45) days of receipt by the related Mortgage Loan Seller of a written invoice from the Asset Representations
Reviewer. If the related Mortgage Loan Seller (x) is insolvent or (y) fails to pay such amount upon completion of any Asset
Review and within ninety (90) days of receiving an invoice from the asset representations reviewer, such fee shall be paid by
the Trust following delivery by the Asset Representations Reviewer of evidence reasonably satisfactory to the Master Servicer
or the Special Servicer, as applicable, of such insolvency or failure to pay such amount; provided, however, that
a statement of non-payment by the Asset Representations Reviewer ninety (90) days after an itemized invoice is delivered by registered
mail to the address listed in this Agreement for the related Mortgage Loan Seller, or to such other address as shall be provided
by such Mortgage Loan Seller for delivery of notice in accordance with this Agreement, together with


 






    -440-


     


    

 


evidence of delivery or attempted
delivery of such invoice and reasonable follow up by phone or e-mail, shall constitute satisfactory evidence delivered by the
Asset Representations Reviewer of such failure to pay such amount. Notwithstanding any payment of such fee by the Trust to the
Asset Representations Reviewer, such fee will remain an obligation of the related Mortgage Loan Seller and the Special Servicer
shall reasonably pursue remedies against such Mortgage Loan Seller to recover any such amounts to the extent paid by the Trust,
provided that the costs of doing so will be a cost of the Trust.


 


(c)            
Notwithstanding the foregoing, the Asset Representations Reviewer Asset Review Fee with respect to a Delinquent Loan (or, in the
case of a Joint Mortgage Loan, the applicable Mortgage Loan Seller Percentage Interest thereof) shall be included in the Purchase
Price for any Mortgage Loan that was the subject of a completed Asset Review and that is repurchased by a Mortgage Loan Seller,
and such portion of the Purchase Price received shall be used to reimburse the Trust for such fees paid to the Asset Representations
Reviewer pursuant to Section 12.02(b).


 


(d)           
The Asset Representations Reviewer shall be liable in accordance herewith only to the extent of the obligations specifically imposed
by this Agreement.


 


Section 12.03   
Resignation of the Asset Representations Reviewer. 
 The Asset Representations Reviewer may resign and be discharged from its obligations hereunder by giving written notice thereof
to the other parties to this Agreement and each Rating Agency. Upon such notice of resignation, the Depositor shall promptly appoint
a successor asset representations reviewer that is an Eligible Asset Representations Reviewer. No resignation of the Asset Representations
Reviewer shall be effective until a successor asset representations reviewer that is an Eligible Asset Representations Reviewer
has been appointed and accepted the appointment. If no successor asset representations reviewer has been so appointed and 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
other party hereto and each Rating Agency in connection with its resignation.


 


Section 12.04   
Restrictions of the Asset Representations Reviewer. Neither the Asset Representations Reviewer nor any of its Affiliates
shall make any investment in any Class of Certificates; provided, however, that such prohibition will 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

    -441-


     


    

 


(a)            
An “Asset Representations Reviewer Termination Event” means any one of the following events whether it shall
be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any
order, rule or regulation of any administrative or governmental body:


 


(i)              
any failure by the Asset Representations Reviewer to observe or perform in any material respect any of its covenants or agreements
or the material breach of any of its representations or warranties under this Agreement, which failure continues unremedied for
a period of thirty (30) days after the date on which written notice of such failure, requiring the same to be remedied, has
been given to the Asset Representations Reviewer by the Trustee or to the Asset Representations Reviewer and the Trustee by the
Holders of Certificates having at least 25% of the aggregate Voting Rights of all then-outstanding Certificates; provided
that if such failure is capable of being cured and the Asset Representations Reviewer certifies to the other parties to this Agreement
that it is diligently pursuing such cure, such thirty (30) day period will be extended by an additional thirty (30) days;


 


(ii)              
any failure by the Asset Representations Reviewer to perform in any material respect any of its obligations hereunder in accordance

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


 


(iii)              
any failure by the Asset Representations Reviewer to be an Eligible Asset Representations Reviewer, which failure shall continue
unremedied for a period of thirty (30) days after the date of written notice of such failure, requiring the same to be remedied,
is given to the Asset Representations Reviewer by any party to this Agreement;


 


(iv)              
a decree or order of a court or agency or supervisory authority having jurisdiction in the premises in an involuntary case under
any present or future federal or state bankruptcy, insolvency or similar law for the appointment of a conservator or receiver
or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the
winding-up or liquidation of its affairs, has been entered against the Asset Representations Reviewer, and such decree or order
remains in force undischarged or unstayed for a period of sixty (60) days;


 


(v)              
the Asset Representations Reviewer shall consent to the appointment of a conservator or receiver or liquidator or liquidation
committee in any insolvency, readjustment of debt, marshaling of assets and liabilities, voluntary liquidation, or similar proceedings
of or relating to the Asset Representations Reviewer or of or relating to all or substantially all of its property; or


 


(vi)              
the Asset Representations Reviewer shall admit in writing its inability to pay its debts generally as they become due, file a
petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors,
or voluntarily suspend payment of its obligations.


 






    -442-


     


    

 


Upon
receipt by the Certificate Administrator (which shall be simultaneously delivered by the Certificate Administrator to the Asset
Representations Reviewer) of written notice of the occurrence of any Asset Representations Reviewer Termination Event, the Certificate
Administrator shall promptly provide written notice to all Certificateholders in accordance with the notice distribution procedures
described in Section 12.01(a), unless the Certificate Administrator has received written notice that such Asset Representations
Reviewer Termination Event has been remedied. If an Asset Representations Reviewer Termination Event shall occur then, and in
each and every such case, so long as such Asset Representations Reviewer Termination Event shall not have been remedied, either
the Trustee (i) may or (ii) upon the written direction of holders of Certificates evidencing not less than 25% of the
Voting Rights (without regard to the application of any Cumulative Appraisal Reduction Amounts), the Trustee shall, terminate
all of the rights and obligations of the Asset Representations Reviewer under this Agreement, other than rights and obligations
accrued prior to such termination (including the right to receive all amounts accrued and owing to it under this Agreement) and
other than indemnification rights (arising out of events occurring prior to such termination), by notice in writing to the Asset
Representations Reviewer. The Asset Representations Reviewer is required to bear all reasonable costs and expenses of each other
party to this Agreement in connection with its termination due to an Asset Representations Reviewer Termination Event. Notwithstanding
anything herein to the contrary, the Depositor and each Sponsor may notify the Certificate Administrator and the Trustee of any
Asset Representations Reviewer Termination Event of which it becomes aware.


 


(b)           
Upon (i) the written direction of the Certificateholders 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 the Certificateholders evidencing more than 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 the proposed successor asset representations reviewer shall be appointed.
As between the Asset Representations Reviewer, on the one hand, and the Certificateholders, on the other, the Certificateholders
may in their sole discretion vote for the termination or not vote for the termination of the Asset Representations Reviewer. If
the Certificateholders entitled to 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.


 






    -443-


     


    

 


(c)            
On or after the receipt by the Asset Representations Reviewer of written notice of termination, subject to this Section 12.05,
all of its authority and power under this Agreement shall be terminated and, without limitation, the terminated Asset Representations
Reviewer shall execute any and all documents and other instruments, and do or accomplish all other acts or things reasonably necessary
or appropriate to effect the purposes of such notice of termination. As soon as practicable, but in no event later than 15 Business
Days after (1) the Asset Representations Reviewer resigns pursuant to Section 12.03 or (2) the Trustee delivers such
written notice of termination to the Asset Representations Reviewer, the Trustee shall appoint a successor asset representations
reviewer that is an Eligible Asset Representations Reviewer. The Trustee shall provide written notice of the appointment of an
Asset Representations Reviewer to the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator,
the Directing Certificateholder, the Directing Holder and each Certificateholder within one Business Day of such appointment.


 


The
Asset Representations Reviewer shall be at all times an Eligible Asset Representations Reviewer and if the Asset Representations
Reviewer ceases to be an Eligible Asset Representations Reviewer, the Asset Representations Reviewer shall immediately notify
the Master Servicer, the Special Servicer, the Trustee, the Operating Advisor, the Certificate Administrator and the Directing
Holder of such disqualification and immediately resign under Section 12.03, 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 is not liable for any failure
to identify and appoint a successor asset representations reviewer for so long as the Trustee uses commercially reasonable efforts
to conduct a search for a successor asset representations reviewer and such failure is not a result of the Trustee’s negligence,
bad faith or willful misconduct in the performance of its obligations hereunder.


 


(d)           
Upon any termination of the Asset Representations Reviewer and appointment of a successor to the Asset Representations Reviewer,
the Trustee shall, as soon as possible, give written notice thereof to the Special Servicer, the Master Servicer, the Certificate
Administrator (who shall, as soon as possible, give written notice thereof to the Certificateholders), the Operating Advisor,
the Sponsors, the Depositor and, if no Consultation Termination Event is continuing, the Directing Holder and each Rating Agency.
If 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).

into such amendment for purposes of availing itself of any indemnity provided to such party under this Agreement.


 


(j)             
Notwithstanding any other provision of this Agreement, for purposes of the giving or withholding of consents pursuant to this
Section 13.01, Certificates registered in the name of the Depositor or any Affiliate of the Depositor shall be entitled

(k)            
This Agreement may not be amended without the consent of any holder of a Companion Loan if such amendment would materially and

amendment of this Agreement, the party requesting such amendment shall provide written notice (which may be by e-mail) of such
proposed amendment to each Other Depositor (and counsel thereto) and the Other Certificate Administrator of each Other Securitization

this Agreement, at the expense of the Trust)), without the consent of any Certificateholder, to add or modify provisions relating
to the applicable Repurchased Note for purposes of the servicing and administration of such Repurchased Note provided that the
amendment shall not adversely affect in any material respect the interests of the Certificateholders, as evidenced by a Rating
Agency Confirmation from each Rating Agency (obtained at the expense of the Repurchasing Mortgage Loan Seller) with respect to
such amendment (or, if no such Rating Agency Confirmation is actually received, by an Opinion of Counsel to such effect). Prior
to the effectiveness of such amendment, if one but not all of the Mortgage Notes with respect to a Joint Mortgage Loan is repurchased,
the terms of Section 3.34 shall govern the servicing and administration of such Joint Mortgage Loan.

No Certificateholder will have any right to vote (except as expressly provided for herein) or in any manner otherwise control
the operation and management of the Trust, or the obligations of the parties hereto, nor may anything herein set forth, or contained

upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and have offered to the Trustee
such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and
the Trustee, for sixty (60) days after its receipt of such notice, request and offer of such indemnity, neglects or refuses to
institute any such action, suit or proceeding. The Trustee will be under no obligation to exercise any of the trusts or powers
vested in it hereunder or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order
or direction of any of the Holders of Certificates unless such Holders have offered to the Trustee reasonable security against
the costs, expenses and liabilities which may be incurred therein or hereby. It is understood and intended, and expressly covenanted
by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates will
have any right in any manner whatsoever by virtue of any provision of this Agreement or the Certificates to affect, disturb or
prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference
to any other such Holder, which priority or preference is not otherwise provided for herein, or to enforce any right under this
Agreement or the Certificates, except in the manner herein or therein provided and for the equal, ratable and common benefit of
all Certificateholders. For the protection and enforcement of the provisions of this Section 13.03(c), each and every
Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 13.06   
Severability of Provisions. If any one or more of the covenants, agreements, provisions or terms of this Agreement shall
be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from
the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect

the validity or enforceability
of the other provisions of this Agreement or of the Certificates or the rights of the Holders thereof.


 


Section 13.07   
Grant of a Security Interest. The Depositor intends that the conveyance of the Depositor’s right, title and interest
in and to the Mortgage Loans pursuant to this Agreement shall constitute a sale and not a pledge of security for a loan. If such
conveyance is deemed to be a pledge of security for a loan, however, the Depositor intends that the rights and obligations of
the parties to such loan shall be established pursuant to the terms of this Agreement. The Depositor also intends and agrees that,
in such event, (i) the Depositor shall be deemed to have granted to the Trustee (in such capacity) a first priority security
interest in the Depositor’s entire right, title and interest in and to the assets comprising the Trust Fund, including without
limitation, the Mortgage Loans, all principal and interest received or receivable with respect to the Mortgage Loans (other than
principal and interest payments due and payable prior to the Cut-off Date and Principal Prepayments received prior to the Cut-off
Date), all amounts held from time to time in the Collection Account, the Distribution Accounts, the Gain-on-Sale Reserve Account,
the Interest Reserve Account and, if established, the REO Account, and all reinvestment earnings on such amounts, and all of the
Depositor’s right, title and interest in and to the proceeds of any title, hazard or other Insurance Policies related to
such Mortgage Loans and (ii) this Agreement shall constitute a security agreement under applicable law. The Depositor shall
file or cause to be filed, as a precautionary filing, a UCC Financing Statement in all appropriate locations promptly following
the initial issuance of the Certificates to reflect the assignments made by the Mortgage Loan Sellers to the Depositor (and the
Trustee) and by the Depositor to the Trustee (copies of which shall be delivered by the Depositor to the Certificate Administrator
shall, at the expense of the Depositor (to the extent reasonable), no later than 10 days following the Closing Date), and the
Certificate Administrator shall prepare and file continuation statements with respect thereto, in each case in the six month period
prior to every fifth anniversary of the date of the initial UCC Financing Statement. The Depositor shall cooperate in a reasonable
manner with the Certificate Administrator in the preparation and filing of such continuation statements. This Section 13.07
shall constitute notice to the Certificate Administrator and the Trustee pursuant to any of the requirements of the applicable
UCC.


 


Section 13.08   
Successors and Assigns; Third Party Beneficiaries. (a)  The provisions of this Agreement shall be binding upon
and inure to the benefit of the respective successors and assigns of the parties hereto, and all such provisions shall inure to
the benefit of the Certificateholders. Each Mortgage Loan Seller (and its respective agents), each Companion Holder (and its respective
agents), each Underwriter, each depositor of a Regulation AB Companion Loan Securitization, each Other Exchange Act Reporting
Party (with respect to its rights under Article XI) and each Initial Purchaser is an intended third-party beneficiary
to this Agreement in respect of the respective rights afforded it hereunder. No other person, including, without limitation, any
Mortgagor, shall be entitled to any benefit or equitable right, remedy or claim under this Agreement. If one, but not all, of
the Mortgage Notes evidencing any Joint Mortgage Loan is repurchased, the applicable Repurchasing Mortgage Loan Seller shall be
a third-party beneficiary of this Agreement to the same extent as if it were a holder of a Serviced Pari Passu Companion Loan,
as contemplated by Section 3.34 hereof.


 


(b)           
Each Serviced Companion Noteholder shall be a third-party beneficiary to this Agreement in respect to the rights afforded it hereunder.
Each of the Other Servicers and the


 






    -458-


     


    

 


Other Trustees shall be a third-party beneficiary to this Agreement in respect to all provisions
herein expressly relating to compensation, reimbursement or indemnification of such Other Servicer and Other Trustee, and any
provisions regarding reimbursement or advances or interest thereon to such Other Servicer or Other Trustee.


 


(c)            
Each of the applicable Non-Serviced Trustee, Non-Serviced Master Servicer, Non-Serviced Special Servicer and any Non-Serviced
Trust holding a related Non-Serviced Companion Loan, shall be a third-party beneficiary to this Agreement in respect to its rights
as specifically provided for herein and under the applicable Non-Serviced Intercreditor Agreement.


 


(d)           
Subject to Section 2.03(k)(ii), Section 2.03(l)(iv) and Section 2.03(l)(v), any Requesting
Certificateholder shall be an express third-party beneficiary to this Agreement for purposes of exercising rights under Section 2.03(k)
through Section 2.03(o).


 


Section 13.09   
Article and Section Headings. The article and section headings herein are for convenience of reference only, and shall
not limit or otherwise affect the meaning hereof.


 


Section 13.10   
Notices to the Rating Agencies. (a)  The Certificate Administrator shall use reasonable efforts promptly to provide
notice to the 17g-5 Information Provider for posting on the 17g-5 Information Provider’s Website pursuant to Section 3.13(c),
(and the related 17g-5 information provider for any class of Serviced Companion Loan Securities to the extent applicable to any

(i)              
any material change or amendment to this Agreement;

(b)           
The Master Servicer shall use reasonable efforts to promptly provide notice to the 17g-5 Information Provider for posting on the

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-1 Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D, Class A-S,
Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class A-1 Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as
Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations


 






     A-1-3


     


    

 


Reviewer,
Midland Loan Services, a Division of PNC Bank, National Association, as Master Servicer, and 3650 REIT Loan Servicing LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in
the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-1
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-1
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall,


 






     A-1-4


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month

interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest


 






     A-1-5


     


    

 


therein);
(x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and the Loan REMIC Residual Interests and (xiii)
the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:


 


		(i)	to
                                         correct any defect or ambiguity in the Pooling and Servicing Agreement;



 


		(ii)	to
                                         cause the provisions in the Pooling and Servicing Agreement to conform or be consistent
                                         with or in furtherance of the statements made in the Prospectus (or in an offering document
                                         for any related non-offered certificates) with respect to the Certificates, the Trust
                                         or the Pooling and Servicing Agreement or to correct or supplement any of its provisions
                                         which may be 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 



 






     A-1-6


     


    

 


Advance
Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such change shall not adversely
affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a
VRR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting such amendment or as evidenced
by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;


 


		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), 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 that the Depositor has determined that such
                                         change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC
                                         or any of the Certificateholders (other than the Transferor) to be subject to a federal
                                         tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S.
                                         Tax Person;



 


		(vi)	to
                                         revise or add any other provisions with respect to matters or questions arising under
                                         the Pooling and Servicing Agreement or any other change; provided that the required
                                         action shall not adversely affect in any material respect the interests of any Certificateholder
                                         (including, for the avoidance of doubt, any Holder of a VRR Interest) 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 Companion Loan Rating Agency

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


 






     A-1-8


     


    

 


Mortgage
Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third
party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially
and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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 Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






     A-1-9


     


    

 


effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions
specifically required to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without
the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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,

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

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-2 Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D, Class A-S,
Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class A-2 Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank,

National
Association, as Certificate Administrator, Wells Fargo Bank, National Association, as Trustee, Park Bridge Lender Services LLC,
as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division of PNC Bank, National Association,
as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not defined herein, capitalized terms
used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-2
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-2
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(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 and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

                                         as evidenced in writing by an Opinion of Counsel at the expense of the party requesting

                                         change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC

                                         to conform to such industry standard, (b) such modification does not adversely affect

		(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 without the consent of the Holders of all Certificates of such Class then-outstanding

                                         under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or any 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 provisions specifically required
to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without the consent of the holder
of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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.


 


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

or the Mortgage Loans.

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-3 Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-SB, Class X-A, Class X-B, Class X-D, Class A-S,
Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class A-3 Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank,


 






     A-3-3


     


    

 


National
Association, as Certificate Administrator, Wells Fargo Bank, National Association, as Trustee, Park Bridge Lender Services LLC,
as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division of PNC Bank, National Association,
as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not defined herein, capitalized terms
used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-3
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-3
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 






     A-3-4


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced

the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month

interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution

     A-3-5


     


    

 


(to
the extent of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the extent of the Trust’s
interest in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to
the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase
Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests
and the Loan REMIC Residual Interests and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:


 


		(i)	to
                                         correct any defect or ambiguity in the Pooling and Servicing Agreement;

                                         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



 






     A-3-6


     


    

 


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 a VRR Interest),
                                         as evidenced in writing by an Opinion of Counsel at the expense of the party requesting
                                         such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency
                                         with respect to such amendment;



 


		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), 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 that the Depositor has determined that such
                                         change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC
                                         or any of the Certificateholders (other than the Transferor) to be subject to a federal
                                         tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S.
                                         Tax Person;



 


		(vi)	to
                                         revise or add any other provisions with respect to matters or questions arising under
                                         the Pooling and Servicing Agreement or any other change; provided that the required
                                         action shall not adversely affect in any material respect the interests of any Certificateholder
                                         (including, for the avoidance of doubt, any Holder of a VRR Interest) or any holder of

                                         (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 no
                                         Control Termination Event is continuing and, with respect to the Mortgage Loans other
                                         than any Excluded Loan as to such party, the Directing Holder, determine that the commercial
                                         mortgage backed securities industry standard for such provisions has changed, in order
                                         to conform to such industry standard, (b) such modification does not adversely affect
                                         the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor
                                         trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel
                                         and (c) each Rating Agency has delivered a Rating Agency Confirmation and Companion

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

                                         with any such amendment or to modify or eliminate the provision related to the risk retention
                                         requirements in the event of such repeal.



 


Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations 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 materially and adversely affect the holders of a Companion Loan without such Companion
Holder’s consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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-3-9


     


    

 


		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or any 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 provisions specifically required
to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without the consent of the holder
of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, to exchange all of its


 






     A-3-10


     


    

 


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
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-SB Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class X-A, Class X-B, Class X-D, Class A-S,
Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class A-SB Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank,


 






     A-4-3


     


    

 


National
Association, as Certificate Administrator, Wells Fargo Bank, National Association, as Trustee, Park Bridge Lender Services LLC,
as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division of PNC Bank, National Association,
as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not defined herein, capitalized terms
used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-SB
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-SB
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 






     A-4-4


     


    

 


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

                                         as evidenced in writing by an Opinion of Counsel at the expense of the party requesting

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided

                                         (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

                                         of the Class R Certificates; provided that 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

                                         action shall not adversely affect in any material respect the interests of any Certificateholder
                                         (including, for the avoidance of doubt, any Holder of a VRR Interest) or any holder of

                                         to conform to such industry standard, (b) such modification does not adversely affect

Notwithstanding

		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage

		(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 without the consent of the Holders of all Certificates of such Class then-outstanding

                                         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

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or any 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 provisions specifically required
to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without the consent of the holder
of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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.


 


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

or the Mortgage Loans.

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class X-A Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-B, Class X-D, Class A-S,
Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class X-A Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as


 






     A-5-3


     


    

 


Certificate
Administrator, Wells Fargo Bank, National Association, as Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as
Asset Representations Reviewer, Midland Loan Services, a Division of PNC Bank, National Association, as Master Servicer, and 3650
REIT Loan Servicing LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-A Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class X-A
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 






     A-5-4


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account 


 






     A-5-5


     


    

 


(to the extent of the Trust’s interest
in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent
of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement
(to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and
the Loan REMIC Residual Interests and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the
lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to
the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:


 


		(i)	to
                                         correct any defect or ambiguity in the Pooling and Servicing Agreement;

                                         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



 






     A-5-6


     


    

 


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 a VRR Interest),
                                         as evidenced in writing by an Opinion of Counsel at the expense of the party requesting
                                         such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency
                                         with respect to such amendment;



 


		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), 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 that 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

                                         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

                                         adversely affect in any material respect the interests of any Certificateholder (including,
                                         for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment

                                         (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 no

                                         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 Companion
                                         Loan Rating Agency Confirmations have been obtained with respect to any Serviced Companion

                                         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 materially and adversely affect the holders of a Companion Loan without such Companion Holder’s
consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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-5-9


     


    

 


		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or any 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 provisions specifically required
to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without the consent of the holder
of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, to exchange all of its


 






     A-5-10


     


    

 


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
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class X-B Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-D, Class A-S,
Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class X-B Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as

Trustee, Park Bridge Lender Services LLC,
as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division of PNC Bank, National Association,
as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not defined herein, capitalized terms
used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-B Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class X-B
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the

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

As

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

                                         (b) such change shall not adversely affect in any material respect the interests of any
                                         Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest),
                                         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

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the

                                         of the Class R Certificates; provided that 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

                                         to conform to such industry standard, (b) such modification does not adversely affect

		(ii)	reduce
                                         the aforesaid percentage of Certificates of any Class the Holders of which are required

                                         under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt

                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or any 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 provisions specifically required
to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without the consent of the holder
of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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.


 


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
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class X-D Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class A-S,
Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class X-D Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as


 






     A-7-3


     


    

 


Trustee,
Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division
of PNC Bank, National Association, as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not
defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-D Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class X-D
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 






     A-7-4


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account 


 






     A-7-5


     


    

 


(to the extent of the Trust’s interest
in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent
of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement
(to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and
the Loan REMIC Residual Interests and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the
lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to
the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:


 


		(i)	to
                                         correct any defect or ambiguity in the Pooling and Servicing Agreement;

                                         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



 






     A-7-6


     


    

 


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 a VRR Interest),
                                         as evidenced in writing by an Opinion of Counsel at the expense of the party requesting
                                         such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency
                                         with respect to such amendment;



 


		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), 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 that the Depositor has determined that such

                                         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 Companion

                                         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 materially and adversely affect the holders of a Companion Loan without such Companion Holder’s
consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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-7-9


     


    

 


		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or any 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 provisions specifically required
to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without the consent of the holder
of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, to exchange all of its


 






     A-7-10


     


    

 


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.

Midland Loan Services, a Division of PNC Bank, National Association, as Master Servicer, and 3650 REIT Loan Servicing LLC, as
Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in
the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-S
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class A-S
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall,


 






     A-8-4


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month

interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues

the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest


 






     A-8-5


     


    

 


therein);
(x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and the Loan REMIC Residual Interests and (xiii)
the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.

Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar

                                         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

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

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance

                                         of the Class R Certificates; provided that 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

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt

                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






     A-8-9


     


    

 


effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions
specifically required to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without
the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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,

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

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class B Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans are to be
serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the
acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby.
In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and Servicing
Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under the Pooling
and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D, Class A-S,
Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates (together
with the Class B Certificates, the “Certificates”; the Holders of Certificates are collectively referred
to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as
Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a
Division of PNC Bank, National Association, as Master


 






     A-9-3


     


    

 


Servicer,
and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class B
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class B Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of


 






     A-9-4


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x)
the rights and remedies of the Depositor under each Mortgage Loan Purchase


 


 



     A-9-5


     


    

 


Agreement
(to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and
the Loan REMIC Residual Interests and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the
lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to
the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:


 


		(i)	to
                                         correct any defect or ambiguity in the Pooling and Servicing Agreement;

                                         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

                                         Accounts or any REO Account; provided that (a) the P&I Advance Date shall
                                         in no event be later than the Business Day prior to the

related
Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest), as evidenced in writing by an Opinion of Counsel at the
expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect
to such amendment;


 


		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), 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 that the Depositor has determined that such
                                         change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC
                                         or any of the Certificateholders (other than the Transferor) to be subject to a federal
                                         tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S.
                                         Tax Person;



 


		(vi)	to
                                         revise or add any other provisions with respect to matters or questions arising under

                                         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

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


 






     A-9-8


     


    

 


rights
of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such
Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s
consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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 Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all


 






     A-9-9


     


    

 


conditions
precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special
Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer
or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the
Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions specifically required to be included in the Pooling and Servicing Agreement by any Designated
Intercreditor Agreement without the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans(solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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

Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class C
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class C Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of


 






     A-10-4


     


    

 


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

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

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance

                                         of the Class R Certificates; provided that 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

                                         to conform to such industry standard, (b) such modification does not adversely affect

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 the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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

shall:


 


		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage

		(ii)	reduce
                                         the aforesaid percentage of Certificates of any Class the Holders of which are required

                                         Holder without the consent of the Holders of all Certificates of such Class then-outstanding
                                         or such Companion Holders, as applicable; or

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations

                                         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 Companion Loan Rating Agency

                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all


 






     A-10-9


     


    

 


conditions
precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special
Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer
or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the
Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions specifically required to be included in the Pooling and Servicing Agreement by any Designated
Intercreditor Agreement without the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class D Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D,
Class A-S, Class B, Class C, Class E, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class D Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as
Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, and Midland Loan Services,
a Division of PNC Bank, National Association, as Master


 






     A-11-3


     


    

 


Servicer,
and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class D
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class D Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of


 






     A-11-4


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x)
the rights and remedies of the Depositor under each Mortgage Loan Purchase


 






     A-11-5


     


    

 


Agreement
(to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and
the Loan REMIC Residual Interests and (xiii) the proceeds of the foregoing (other than any interest earned on deposits in the
lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to
the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:


 


		(i)	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

                                         Accounts or any REO Account; provided that (a) the P&I Advance Date shall
                                         in no event be later than the Business Day prior to the

related
Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest), as evidenced in writing by an Opinion of Counsel at the
expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect
to such amendment;


 


		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), 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 that the Depositor has determined that such

                                         to conform to such industry standard, (b) such modification does not adversely affect

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


 






     A-11-8


     


    

 


rights
of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such
Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s
consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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 Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all


 






     A-11-9


     


    

 


conditions
precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special
Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer
or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the
Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions specifically required to be included in the Pooling and Servicing Agreement by any Designated
Intercreditor Agreement without the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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

This

interest in a Trust Fund, including the distributions to be made with respect to the Class E Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D,
Class A-S, Class B, Class C, Class D, Class F-RR, Class G-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class E Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as


 






     A-12-3


     


    

 


Trustee,
Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division
of PNC Bank, National Association, as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not
defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class E
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class E Certificates
is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(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 and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

duties and immunities of the Certificate Administrator and Trustee.


 


As

the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar

                                         as evidenced in writing by an Opinion of Counsel at the expense of the party requesting

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided

                                         of the Class R Certificates; provided that the Depositor has determined that such
                                         change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or any 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 provisions specifically required
to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without the consent of the holder
of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, to exchange all of its


 






     A-12-10


     


    

 


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
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class F-RR Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D,
Class A-S, Class B, Class C, Class D, Class E, Class G-RR, Class NR-RR, Class R and Class Z Certificates (together
with the Class F-RR Certificates, the “Certificates”; the Holders of Certificates are collectively referred
to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as


 






     A-13-4


     


    

 


Trustee,
Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division
of PNC Bank, National Association, as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not
defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class F-RR
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class F-RR
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall,


 






     A-13-5


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest


 






     A-13-6


     


    

 


therein);
(x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and the Loan REMIC Residual Interests and (xiii)
the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:

                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided

                                         (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

                                         of the Class R Certificates; provided that 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

                                         the Pooling and Servicing Agreement or any other change; provided that the required
                                         action shall not adversely affect in any material respect the interests of any Certificateholder
                                         (including, for the avoidance of doubt, any Holder of a VRR Interest) or any holder of

                                         Control Termination Event is continuing and, with respect to the Mortgage Loans other
                                         than any Excluded Loan as to such party, the Directing Holder, determine that the commercial
                                         mortgage backed securities industry standard for such provisions has changed, in order
                                         to conform to such industry standard, (b) such modification does not adversely affect
                                         the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor
                                         trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel

		(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

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


 






     A-13-9


     


    

 


Mortgage
Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third
party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially
and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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 Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the


 






     A-13-10


     


    

 


effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions
specifically required to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without
the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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,

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

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class G-RR Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D,
Class A-S, Class B, Class C, Class D, Class E, Class F-RR, Class NR-RR, Class R and Class Z Certificates
(together with the Class G-RR Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as


 






     A-14-4


     


    

 


Trustee,
Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division
of PNC Bank, National Association, as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not
defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
G-RR Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class G-RR
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall,


 






     A-14-5


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month

interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest


 






     A-14-6


     


    

 


therein);
(x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and the Loan REMIC Residual Interests and (xiii)
the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.

Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate

Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar

                                         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

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

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), or Companion Holder;

                                         Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer
                                         of the Class R Certificates; provided that the Depositor has determined that such
                                         change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC
                                         or any of the Certificateholders (other than the Transferor) to be subject to a federal
                                         tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S.

		(vi)	to
                                         revise or add any other provisions with respect to matters or questions arising under
                                         the Pooling and Servicing Agreement or any other change; provided that the required
                                         action shall not adversely affect in any material respect the interests of any Certificateholder
                                         (including, for the avoidance of doubt, any Holder of a VRR Interest) or any holder of

Mortgage
Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third
party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may materially
and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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

                                         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 Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the


 


 



     A-14-10


     


    

 


effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions
specifically required to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without
the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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,

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

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class NR-RR Certificates. The Trust
Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D,
Class A-S, Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class R and Class Z Certificates
(together with the Class NR-RR Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as

Trustee,
Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a Division
of PNC Bank, National Association, as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the extent not
defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


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


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class NR-RR
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.


 


Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class NR-RR
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall,


 






     A-15-5


     


    

 


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


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced

the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month

interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues

the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),

Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution

Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest


 






     A-15-6


     


    

 


therein);
(x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and the Loan REMIC Residual Interests and (xiii)

Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the

Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar

                                         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;

by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;


 


		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), or Companion Holder;

                                         of the Class R Certificates; provided that 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

                                         the Pooling and Servicing Agreement or any other change; provided that the required
                                         action shall not adversely affect in any material respect the interests of any Certificateholder
                                         (including, for the avoidance of doubt, any Holder of a VRR Interest) 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

                                         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

		(ii)	reduce
                                         the aforesaid percentage of Certificates of any Class the Holders of which are required

                                         Holder without the consent of the Holders of all Certificates of such Class then-outstanding

                                         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 Companion Loan Rating Agency

                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the 


 



     A-15-10


     


    




 


effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions
specifically required to be included in the Pooling and Servicing Agreement by any Designated Intercreditor Agreement without
the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class R Certificates. The Trust Fund,
described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily
properties held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created, and the Mortgage Loans
are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue
of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement and is bound
thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the Pooling and
Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also issued under
the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class X-B, Class X-D,
Class A-S, Class B, Class C, Class D, Class E, Class F-RR, Class G-RR, Class NR-RR and Class Z Certificates
(together with the Class R Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).


 


This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of March 1,
2021 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp.,
as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wells Fargo Bank, National Association, as
Trustee, Park Bridge Lender Services LLC, as Operating Advisor and as Asset Representations Reviewer, Midland Loan Services, a
Division of PNC Bank, National Association, as Master Servicer, and 3650 REIT Loan Servicing LLC, as Special Servicer. To the
extent not defined


 






     A-16-3


     


    

 


herein,
capitalized terms used herein shall have the meanings assigned thereto in the Pooling and Servicing Agreement.


 


This
Certificate represents a “residual interest” in four “real estate mortgage investment conduits,” as those
terms are defined, respectively, in Sections 860G(a)(2) and 860D of the Internal Revenue Code of 1986, as amended.


 


Each
Holder of this Certificate, by acceptance hereof, agrees to treat, and take no action inconsistent with the treatment of, this
Certificate in accordance with the preceding sentence for purposes of federal income taxes, state and local income and franchise
taxes and other taxes imposed on or measured by income. The Certificate Administrator shall be the “partnership representative”
(within the meaning of Section 6223 of the Code for each Trust REMIC). The Certificate Administrator makes no representation or
warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates and the Mortgage Loans
and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of the aggregate amount, if any, allocable to the Class R Certificates for such Distribution Date, all as more
fully described in the Pooling and Servicing Agreement.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(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


 






     A-16-4


     


    

 


Certificateholders
to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one
year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator,
directly or through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender
of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses
of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable
to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator
as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 4.01(h) of the Pooling and Servicing Agreement.


 


This
Certificate is limited in right of payment to, among other things, certain collections and recoveries in respect of the Mortgage
Loans, as more specifically set forth herein and in the Pooling and Servicing Agreement.


 


As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non-Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Loan REMIC Residual Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x)
the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; (xii) the Loan REMIC Regular Interests and the Loan REMIC Residual Interests and (xiii)
the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral

accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).


 


This
Certificate does not purport to summarize the Pooling and Servicing Agreement, and reference is made to the Pooling and Servicing
Agreement for the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights,
duties and immunities of the Certificate Administrator and Trustee.


 


As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender
for registration of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Certificates in authorized denominations, in like aggregate
interest and of the same Class.


 


Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate
Administrator or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.


 


The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent
of any of the Certificateholders or the Companion Holders:


 


		(i)	to
                                         correct any defect or ambiguity in the Pooling and Servicing Agreement;

                                         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 a VRR Interest),
                                         as evidenced in writing

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), or Companion Holder;

                                         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 that 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

     A-16-8


     


    

 


Agreement,
without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without
such Companion Holder’s consent.


 


The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less
than a majority of the aggregate Percentage Interests constituting each such Class of Certificates 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 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 Companion Loan Rating Agency
                                         Confirmations with respect to any Serviced Companion Loan Securities and, if required
                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power


 






     A-16-9


     


    

 


granted
to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition
of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions specifically required to be included in the Pooling and Servicing
Agreement by any Designated Intercreditor Agreement without the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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.

Certificate in accordance with the preceding sentence for purposes of federal income taxes, state and local income and franchise
taxes and other taxes imposed on or measured by income.


 


The
Certificate Administrator makes no representation or warranty as to any of the statements contained herein or the validity or
sufficiency of the Certificates and the Mortgage Loans and has executed this Certificate in its limited capacity as Certificate
Administrator under the Pooling and Servicing Agreement.


 


Pursuant
to the terms of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution
on any Certificate), on the 4th Business Day following the determination date of each month, commencing in April 2021 (each such
date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount, if any, allocable to the Class Z Certificates for such Distribution
Date, all as more fully described in the Pooling and Servicing Agreement.


 


All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution (determined without regard to any possible future reimbursement
of Realized Losses previously allocated to such Certificate) on each Certificate will be made in like manner, but only upon presentment
and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution.


 


Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of


 






     A-17-3


     


    

 


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

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided

                                         (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

Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holder of the VRR Interest to
the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less

		(ii)	reduce
                                         the aforesaid percentage of Certificates of any Class the Holders of which are required

                                         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 Companion Loan Rating Agency

                                         under the related Intercreditor Agreement, the consent of the holder of any Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.



 


Notwithstanding
the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all


 






     A-17-8


     


    

 


conditions
precedent have been satisfied and that such amendment or the exercise of any power granted to the Master Servicer, the Special
Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer
or any other specified person in accordance with such amendment will not result in the imposition of a tax on any portion of the
Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or any 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 provisions specifically required to be included in the Pooling and Servicing Agreement by any Designated
Intercreditor Agreement without the consent of the holder of the related Companion Holder(s).


 


The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans
and any REO Mortgage Loans held by the Trust is equal to or less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage
Loans (solely for the purposes of this calculation, if a Mortgage Loan with an Anticipated Repayment Date is still an asset of
the Trust and such right is being exercised after its respective Anticipated Repayment Date, then any such Mortgage Loan will
be excluded from the then-aggregate Stated Principal Balance of the pool of Mortgage Loans and from the aggregate Stated Principal
Balance of the pool of Mortgage Loans as of the Cut-off Date) as set forth in the Pooling and Servicing Agreement.


 


Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-SB, Class A-S, Class X-A, Class X-B, Class X-D, Class B, Class C, Class D and Class E Certificates have been reduced to zero
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates)), the Sole Certificateholder shall have the right, with the consent of the Master
Servicer if the then-outstanding aggregate Stated Principal Balance of the Mortgage Loans and each REO Property is greater than
or equal to 8.125% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-Off Date, 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,

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

or the Mortgage Loans.

resell, pledge or transfer the Certificate only to certain investors in certain exempted transactions) as expressed herein.

from such registration or qualification is available.

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) “Westchester Loan REMIC”, (ii) “Voyant
Loan REMIC”, (iii) “Lower-Tier REMIC” and (iv) “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 Freddie Mac, a majority of its board of directors is not selected by such governmental unit), (ii)
a foreign government, any international organization or any agency or instrumentality of any of the foregoing, (iii) any organization
which is exempt from the tax imposed by Chapter 1 of the Code (including the tax imposed by Section 511 of the Code on unrelated
business taxable income) on any excess inclusions (as defined in Section 860E(c)(1) of the Code) with respect to the Class R Certificates
(except certain farmers’ cooperatives described in Section 521 of the Code), (iv) rural electric and telephone cooperatives
described in Section 1381(a)(2)(C) of the Code and (v) 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 either
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


 


(iii)       the
present value of the anticipated tax savings associated with holding such Class R Certificate as the related REMIC generates losses.


 



    Exhibit D-1-2


     


    

 





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 it will not consummate any
such transfer if it knows or believes that any representation contained in such affidavit and agreement is false.


 



    Exhibit D-1-3


     


    

 





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 “partnership representative” of each
Trust REMIC pursuant to Section 10.01 of the Pooling and Servicing Agreement.


 


Capitalized
terms used but not defined herein have the meanings assigned thereto in the Pooling and Servicing Agreement.

as contemplated by Treasury regulation Section 1.860E-1(c)(4)(i) and, as a result of that investigation, the Transferor has determined
that the Transferee has historically paid its debts as they became due and has found no significant evidence to indicate that
the Transferee will not continue to pay its debts as they become due in the future. The Transferor understands that the transfer
of the Residual Certificates may not be


 



    Exhibit D-2-1


     


    

 


respected for United States income tax purposes (and the Transferor may continue to be
liable for United States income taxes associated therewith) unless the Transferor has conducted such an investigation.

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.


 


Obligation
to Return Evaluation Material. Promptly upon written request by or on behalf of the relevant Furnishing Entity,

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 obtained in an oral communication; provided, that any Evaluation
Material so retained by the NRSRO will remain subject to this Confidentiality Agreement and the NRSRO will remain bound by the
terms of this Confidentiality Agreement.


 


Violations
of this Confidentiality Agreement. The NRSRO will be responsible for any breach of this Confidentiality Agreement
by you, the NRSRO or any NRSRO Representative.


 


You
agree promptly to advise each relevant Furnishing Entity in writing of any misappropriation or unauthorized disclosure or use
by any person of the Confidential Information which may come to your attention and to take all steps reasonably requested by such
Furnishing Entity to limit, stop or otherwise remedy such misappropriation, or unauthorized disclosure or use.


 


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 to any other remedy to which a Furnishing Entity may be entitled at law or in equity. It is further understood and
agreed that no failure to or delay in exercising any right, power or privilege hereunder shall preclude any other or further exercise
of any right, power or privilege.


 


Term.

provided a credit rating on a Security, your obligations under this Confidentiality Agreement will survive indefinitely.

a written statement by the Special Servicer that any particular loan or property in question and the release thereof is subject
to and included under this power of attorney and the PSA.

                                         ____________________



 


Reference
is made to the Pooling and Servicing Agreement described above. Capitalized terms used but not defined herein have the meanings
assigned to such terms in the Pooling and Servicing Agreement.


 


As
Servicer under the Pooling and Servicing Agreement, we hereby:


 


(a)       Notify
you that the Mortgagor has consummated a defeasance of the Mortgage Loan pursuant to the terms of the Mortgage Loan, 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 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 



    Exhibit U-3


     


    

 


exceed such Defeasance Obligor’s interest expense for the Mortgage Loan (or the allocated portion thereof in a partial
defeasance) for such year.


 


(ix)       The
Mortgage Loan is not among the ten (10) largest loans in the pool as of the date of the Current Report (as defined below). The
entire principal balance of the Mortgage Loan as of the date of defeasance was less than both $[______] and five percent of pool
balance, which is less than [__]% of the aggregate Certificate Balance of the Certificates as of the date of the most recent Distribution
Date Statement received by us (the “Current Report”).


 


(x)       The
Master Servicer has received opinions of counsel stating that the Trustee on behalf of the Trust possesses a valid, perfected
first priority security interest in the defeasance collateral and that the documents executed in connection with the defeasance
are enforceable in accordance with their respective terms.


 


(c)       
Certify that Exhibit B hereto is a list of the material agreements, instruments, organizational documents for the Defeasance
Obligor, and opinions of counsel and independent accountants executed and delivered in connection with the defeasance.


 


(d)       
Certify that the individual under whose hand the Master Servicer has caused this Notice and Certification to be executed did constitute
a Servicing Officer as of the date of the defeasance described above.


 


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


 




    Exhibit U-4


     


    

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

                                         RECOMMENDATION OF REPLACEMENT OF SPECIAL SERVICER, IF APPLICABLE]



 


In
connection with the assessment set forth in this report, the Operating Advisor:


 


		1.	Reviewed
                                         the Asset Status Reports, the Special Servicer’s assessment of compliance report,
                                         attestation report by a third party regarding the Special Servicer’s compliance
                                         with its obligations and net present value calculations, Collateral Deficiency Amount
                                         calculations and Appraisal Reduction Amount calculations and [LIST OTHER REVIEWED INFORMATION]
                                         for the following [●] Specially Serviced Loans: [List related Mortgage Loans]



 


		2.	Consulted
                                         with the Special Servicer as provided under the Pooling and Servicing Agreement. The
                                         Operating Advisor’s analysis of the Asset Status Reports (including related net
                                         present value calculations, Collateral Deficiency Amount calculations and Appraisal Reduction
                                         Amount calculations) related to the Specially Serviced Loans should be considered a limited
                                         investigation and not be considered a full or limited audit. For instance, we did not
                                         re-engineer the quantitative aspects of their net present value calculator, visit any
                                         property, visit the Special Servicer, visit the Directing Certificateholder or interact
                                         with any borrower. In addition, our review of the net present value calculations, Collateral
                                         Deficiency Amount calculations 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.

Ladies
and Gentlemen:


 


Reference
is hereby made to that certain Pooling and Servicing Agreement dated as of March 1, 2021 (the “Pooling and Servicing
Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Midland Loan Services, a
Division of PNC Bank, National Association, as Master Servicer, 3650 REIT Loan Servicing LLC, as Special Servicer, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, and Park Bridge Lender Services LLC, as Asset Representations
Reviewer and as Operating Advisor. Defined terms used herein and not otherwise defined shall have the meanings set forth in the
Pooling and Servicing Agreement.


 


Midland
Loan Services, a Division of PNC Bank, National Association (“Midland”)/3650 REIT Loan Servicing LLC (“3650
REIT”) 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 



    Exhibit X-1


     


    

 


[_____] [__], 20[__]


Page 2 


 


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.


 


Midland/3650
REIT 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 Midland/3650 REIT by third parties, (b) may not have been
verified by Midland/3650 REIT, and (c) may be incomplete or contain inaccuracies. The Company agrees that Midland/3650 REIT, the
[“Master Servicer”/”Special Servicer”] (as defined in the Pooling and Servicing Agreement)
and their respective Representatives (as defined below) shall not have any liability to the Company or its Representatives resulting
from (x) any inaccuracies or omissions in the Confidential Information, (y) any use of the Confidential Information, or (z) Midland/3650
REIT’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 Midland/3650 REIT; (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 Midland/3650 REIT; (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 Midland/3650 REIT’s election): (i) responses to reasonable
written inquiries received from the Company, (ii) conference calls conducted on a reasonably scheduled basis with Midland/3605
REIT’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”). Midland/3650 REIT 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) Midland/3650 REIT 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. Midland/3650 REIT shall cease to provide the Company with Confidential Information if Midland/3650
REIT has actual knowledge that the Company or its Representatives are affiliates of any borrower under the Mortgage Loan documents
and Midland/3650 REIT 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. Midland/3650 REIT’s remedies hereunder, at law or at equity, are
cumulative and may be combined.


 



    Exhibit X-2

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)

ASSET
REVIEW PROCEDURES


 




 Subject to the Pooling and Servicing Agreement, this Exhibit sets forth Asset Representations Reviewer’s review procedures
for each Delinquent Loan based on the information provided for an Asset Review. Capitalized terms used herein and not defined
herein shall have the meanings ascribed to them in the Pooling and Servicing Agreement. In the event of any conflict between this
Exhibit QQ and the terms of the Pooling and Servicing Agreement, the Pooling and Servicing Agreement shall control and govern
the Asset Representation Reviewer’s responsibilities and duties with respect to Asset Reviews.


 


Call
for Review and Collection and Inventory of Review Materials


 


Step
1 Asset Representations Reviewer (“ARR”) receives the following items before beginning its review
from the parties specified in Section [ ] of the Pooling and Servicing Agreement:


 


		■	Notice
                                         of Asset Review Trigger (with attachments)



 


		■	Asset
                                         Review Vote Election



 


		■	Notice
                                         of Affirmative Asset Review Vote



 


		■	List
                                         of all Delinquent Loans subject to the Asset Review



 


		■	Review
                                         Materials for each Delinquent Loan via Secure Data Room access, including the Diligence
                                         File



 


		■	Any
                                         Unsolicited Information (if applicable)



 


Step
2 For each Delinquent Loan, ARR inventories all Review Materials to which ARR is provided access in the Secure
Data Room to determine what, if any, Review Materials for such Delinquent Loan are missing, using the list of documents in Section
[ ] through Section [ ] of this Agreement, any comparable lists included in the related Mortgage Loan Purchase Agreement,
and any closing checklist from the origination of such Delinquent Loan, to guide its review and determination


 


Step
3 If ARR determines that the information made available to it in the Secure Data Room with respect to any Delinquent
Loan is missing any documents required to complete an Asset Review of such Delinquent Loan, ARR shall prepare a list of such missing
documents and notify Master Servicer (with respect to Non-Specially Serviced Loans) and Special Servicer (with respect to Specially
Serviced Loans) of such missing documents. If the Master Servicer or Special Servicer, as applicable, does not provide such document
as provided in the Pooling and Servicing Agreement, the ARR shall notify the related Mortgage Loan Seller of such missing information

Analysis
and Testing of Representations and Warranties


 


Step
4 For each Delinquent Loan for which ARR has received all Review Materials required to complete an Asset Review
of such Delinquent Loan, ARR tests such Delinquent Loan for compliance with each representation and warranty made by the related
Mortgage Loan Seller with respect to such Delinquent Loan as follows:


 


		■	ARR
                                         reviews each representation and warranty and each item included in the Review Materials
                                         applicable or related to such representation or warranty to determine whether there is
                                         any evidence that such representation or warranty was not true when made by the related
                                         Mortgage Loan Seller



 


		■	For
                                         each representation and warranty, ARR lists



 


		●	all
                                         items from the Review Materials reviewed or used in its testing of such representation
                                         and warranty



 


		●	whether
                                         ARR has determined that there is any evidence that such representation or warranty was
                                         not true when made by the related Mortgage Loan Seller, and



 


		o	if
                                         so, stating the aspect of the applicable representation or warranty that does not appear
                                         to have been true when made by the related Mortgage Loan Seller and ARR’s basis
                                         for its conclusion



 


		o	completing
                                         the Asset Review Report by setting forth, for each Delinquent Loan, the information contemplated
                                         herein with respect to each representation and warranty



 


ARR
will not attempt (and has no obligation) to determine the materiality of any potential breach of a representation or warranty
that it discovers evidence of during its review as contemplated herein.
