		(1)	Each
                                         A Note is pari passu in right of payment with the other A Note.

 

Note A-A-1 is referred to herein
as the “Trust A Note”. Note A-B is referred to herein as the “Trust A-B Note”. Note A-A-2
is referred to herein as the “Non-Trust A Note”. The Trust A Note and the Non-Trust A Note are referred to herein
as the “A Notes”. The Trust A Note and the Trust A-B Note are referred to herein as the “Trust Notes”.
Note B is referred to herein as the “Non-Trust B Note”.

 

The portion of the Whole Loan
evidenced by the Trust Notes is referred to herein as the “Trust Loan”, having an aggregate principal balance
as of the Cut-off Date of $143,000,000. The portion of the Whole Loan evidenced by the Non-Trust A Note is referred to as herein
as the “Senior Companion Loan”, having a principal balance as of the Cut-off Date of $33,000,000. The portion
of the Whole Loan evidenced by the Non-Trust B Note is referred to herein as the “Junior Companion Loan”, having

The Trust Loan was sold and assigned
by the Lender to the Depositor pursuant to a trust loan purchase and sale agreement, dated as of the date hereof, by and between
the Lender and the Depositor (the “Loan Purchase Agreement”). The Companion Loans will not be assets of the
Trust.

 

     

     

    

 

The Trust Loan and the Companion
Loans are subject to the terms and conditions of the Co-Lender Agreement, dated as of May 25, 2017, between NREC, as holder of
the Trust Note, and NREC, as holder of the Companion Note (the “Co-Lender Agreement”).

 

As provided for herein, the Certificate
Administrator shall elect or shall cause elections to be made to treat designated portions of the Trust Fund for federal income
tax purposes as two separate real estate mortgage investment conduits (the “Upper-Tier REMIC” and the “Lower-Tier
REMIC” and, each, a “REMIC”). The Class A, Class X-A, Class X-B, Class B, Class C, Class D and Class
E Regular Interests will represent “regular interests” in the Upper-Tier REMIC. The Class LA, Class LB, Class LC,
Class LD and Class LE Uncertificated Interests will represent “regular interests” in the Lower-Tier REMIC. The Class R
Certificates will evidence the sole Class of “residual interests” in each of the Upper-Tier REMIC and Lower-Tier REMIC
for purposes of the REMIC Provisions under federal income tax law.

 

The portions of the Trust Fund
consisting of the Specific Grantor Trust Assets shall be treated as a grantor trust under subpart E, part I of subchapter J
of the Code (the “Grantor Trust”) for federal income tax purposes. Each Class of Certificates (other than the
Class R Certificates) shall represent undivided beneficial interests in the portion of the Grantor Trust consisting of the
Specific Grantor Trust Assets with the corresponding alphabetic or alphanumeric designation.

 

In exchange for the Trust Loan,
the Trust will issue to the Depositor the Class A, Class X-A, Class X-B, Class B, Class C, Class D, Class E and Class R Certificates
(collectively, the “Certificates”), which Certificates in the aggregate will evidence the entire beneficial
interest in the Trust Fund. The Trust Fund consists principally of the Note, the Mortgage and the Loan Documents.

 

The Depositor intends to sell
the Certificates in an offering exempt from the registration requirements of the federal securities laws.

 

UPPER-TIER REMIC

 

The Regular Interests will evidence
“regular interests” in the Upper-Tier REMIC created hereunder. The Class UT-R Interest will constitute the
sole Class of “residual interests” in the Upper-Tier REMIC created hereunder, and will be evidenced by the Class R
Certificates.

 

LOWER-TIER REMIC

 

The Class LA, Class LB,
Class LC, Class LD and Class LE Uncertificated Interests will evidence “regular interests” in the Lower-Tier
REMIC created hereunder. The Class LT-R Interest will constitute the sole Class of “residual interests” in the
Lower-Tier REMIC created hereunder and will be evidenced by the Class R Certificates. The following table sets forth the
initial Lower-Tier Principal Amounts and Pass-Through Rates for the Uncertificated Lower-Tier Interests and the Class
UT-R Interest comprising the interests in the Lower-Tier REMIC created hereunder:

		(2)	The
                                         Class LT-R Interest (evidenced by the Class R Certificates) will not have a Certificate
                                         Balance or Notional Amount, will not bear interest and will not be entitled to distributions
                                         of Yield Maintenance Premiums. Any Available Funds constituting assets remaining in the
                                         Lower-Tier Distribution Account after distributing the Lower-Tier Distribution
                                         Amount shall be distributed to the Holders of the Class R Certificates in respect
                                         of the Class LT-R Interest (but only to the extent of the Available Funds for such Distribution
                                         Date, if any, remaining in the Lower-Tier Distribution Account).

 

All covenants and agreements
made by the Depositor herein are for the benefit and security of the Certificateholders and the Trustee as Holder of the Uncertificated
Lower-Tier Interests. The Depositor, the Servicer, the Special Servicer, the Certificate Administrator and the Trustee are entering
into this Agreement, and the Trustee is accepting the trusts created hereby, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged.

 

THE GRANTOR TRUST

 

The Certificates (other than
the Class R Certificates) shall represent undivided beneficial interests in the related portions of the Grantor Trust as described
herein. As provided herein, the Certificate Administrator shall not take any actions that would cause the portion of the Trust
Fund consisting of the Grantor Trust (i) to fail to maintain its status as a “grantor trust” under federal income tax
law or (ii) to be treated as part of any Trust REMIC.

Payments, (iv) 60 days after an extension of the Maturity Date of the Whole Loan (except for an extension within the time
periods described in clause (ii) above), (v) immediately after a receiver has been appointed in respect of the Property on
behalf of the Trust and the Companion Loan Holders or any other creditor, (vi) immediately after the Borrower declares, or
becomes the subject of, bankruptcy, insolvency or similar proceedings, admits in writing the inability to pay its debts as they
become due or makes an assignment for the benefit of creditors, or (vii) immediately after the Property becomes a Foreclosed Property;
provided that with respect to the Appraisal Reduction Event described in clause (i), to the extent that (x) the
Borrower becomes current on its payment obligations with respect to the Notes (including payment in full of (A) all accrued and
unpaid interest on the Notes (including accrued and unpaid Default Interest, if any, thereon) and (B) all Advances made by
the Servicer and/or the Trustee and interest thereon) and remain current for a period of twelve consecutive months and (y) an

to be due equal to the Monthly Payment for the Trust Loan calculated by the Servicer for the Assumed Payment Date (excluding the
Balloon Payment and Default Interest) at the Mortgage Rate and based on the same amortization schedule, if any, used to determine
the Monthly Debt Service Payment Amount, in each case as such terms may have been modified, and such Maturity Date may have been
extended, in connection with a bankruptcy or similar

 

    -9-

rata basis), then to the Trust A-B Note (to reduce the outstanding principal balance of the Trust A-B Note), and then to the
Non-Trust B Note (to reduce the outstanding principal balance of the Non-Trust B Note), in each case until their respective principal

of the cumulative amount of the reductions (if any) in the amount of the interest portion of the related Monthly Payment Advances
and Senior Companion Loan Advances that have theretofore occurred under Section 3.23(a) in connection with related
Appraisal Reduction Amounts (to the extent that collections have not been applied as recovery of accrued and unpaid interest pursuant
to this clause fifth on earlier dates) (such accrued and unpaid interest to be applied and sequentially to accrued and unpaid
interest on the Trust A Note and Non-Trust A Note (on a pro rata basis), then to the Trust A-B Note and then to the Non-Trust
B Note, in that order); sixth, as a recovery of related Yield Maintenance Premiums then due and owing under the Whole Loan;
seventh, as a recovery of any Default Interest or late charges then deemed to be due and owing under the Whole Loan; and

(c)           
All net present value calculations and determinations made under this Agreement with respect to the Trust Loan or the Whole
Loan, as applicable, or the Property or Foreclosed Property (including for purposes of the definition of “Accepted Servicing
Practices”) shall be made using a discount rate appropriate for the type of cash flows being discounted; namely (i) for
principal and interest payments on the Whole Loan or sale of the Whole Loan if it is in default (in such case, the “Defaulted
Loan”), the higher of (1) the rate determined by the Special Servicer that approximates the market rate that would
be obtainable by the Borrower on similar debt of the Borrower as of such date of determination and (2) the Mortgage Rate on
the Whole Loan based on its outstanding principal balance and (ii) for all other cash flows, including property cash flow,
the “discount rate” set forth in the most recent Appraisal (or update of such Appraisal).

provided that if the Depositor cannot deliver,
or cause to be delivered, any of the documents and/or instruments referred to in clauses (C), (E), (F), (G) and (M) above
with evidence of filing or recording thereon (if intended to be recorded or filed), because of a delay caused by the public filing
or recording office where such document or instrument has been delivered for filing or recordation, or because the timing of the
Closing Date is such that it would not be feasible to obtain such documents from such public filing or recording office in sufficient
time to meet the delivery requirements of this Section 2.1(b), the delivery requirements of this Section 2.1(b)
shall be deemed to have been satisfied on a provisional basis as of the Closing Date as to such non-delivered document or instrument,
and such non-delivered document or instrument shall be deemed to have been included in the Mortgage File, if a duplicate original
or a photocopy of such non-delivered document or instrument (certified by the applicable public filing or recording office, the
applicable title insurance company or the Depositor to be a true and complete copy of the original thereof submitted for filing
or recording) is delivered to the Custodian on or before the Closing Date, and either the original of such non-delivered document
or instrument, or a photocopy thereof (certified by the appropriate county recorder’s office, in the case of the documents
and/or instruments referred to in clauses (C), (E), (F), (G) and (M) above, to be a true and complete copy of the original
thereof submitted for recording), with evidence of filing or recording thereon, is delivered to the Custodian within 180 days of
the Closing Date (or within such longer period, not to exceed 12 months, after the Closing Date as the Custodian may consent to,
which consent shall not be unreasonably withheld so long as the Depositor is, as certified in writing to the Custodian no less
often than every 90 days, attempting in good faith to obtain from the appropriate public filing office or county recorder’s
office, as applicable, such original or photocopy); provided, further, that in those instances where the public recording
office retains an original Mortgage, an original Assignment of Mortgage, an original Assignment of Leases, or any other Collateral
Security Document, if applicable, after any has been recorded, the obligations hereunder of the Depositor and the obligations of
the Loan Seller under the Loan Purchase Agreement shall be deemed to have been satisfied upon delivery to the Custodian of a copy
of the Mortgage, Assignment of Mortgage or assignment of a Collateral Security Document, if applicable, certified by the public
recording office or the title insurance company to be a true and complete copy of the recorded original thereof.

 

In addition, the Depositor shall
deliver or cause to be delivered to the Servicer for its review all required insurance policies or certificates issued by the insurers
showing such insurance to be in effect on the Closing Date, together with proof of payment of premiums relating thereto then due
and payable (which may consist of such policies or certificates).

 

The Depositor shall provide,
or cause to be provided, the Servicer on or prior to the Closing Date, at its own expense, with copies of all such documents in
its possession constituting part of the Mortgage File. In the event that any Letter of Credit is delivered by the Borrower under
the Loan Documents after the Closing Date, the Servicer shall hold the original of such Letter of Credit on behalf of the Trust
and the Companion Loan Holders and deliver a copy of such Letter of Credit to the Trustee.

 

    -68-

     

    

 

The Depositor shall cause the
Loan Seller to record or cause a third party to record in the appropriate public recording office the documents and/or instruments
referred to in clauses (C), (E), (F), (G) and (M) above.

 

The ownership of the Trust Notes,
the Mortgage, the Collateral Security Documents and all other contents of the Mortgage File shall be vested in the Trust or the
Trustee in trust for the benefit of the Certificateholders and, except in the case of the Trust Notes, the Companion Loan Holders.
The Depositor, the Servicer and the Special Servicer agree to take no action inconsistent with the Trustee’s ownership of
the Trust Loan and to promptly indicate to all inquiring parties that the Trust Loan has been sold and to claim no ownership interest
in the Trust Loan. All original documents relating to the Whole Loan or Trust Loan that are not delivered to the Custodian are
and shall be held by the Depositor, the Servicer or the Special Servicer, as the case may be, in trust for the benefit of the Certificateholders
and, except in the case of the Trust Notes, the Companion Loan Holders. In the event that any such original document is required
pursuant to the terms of this Section 2.1(b) to be a part of the Mortgage File, such document shall be delivered promptly
to the Custodian.

 

The conveyance of the Trust Loan
and the related rights and property accomplished hereby is absolute and is intended by the parties hereto to constitute an absolute
sale and transfer of the Trust Loan and such other related rights and property by the Depositor to the Trustee in trust for the
benefit of the Certificateholders, in exchange for the Certificates being sold by the Depositor. Furthermore, it is not intended
that such conveyance be a pledge of security for a loan. If such conveyance is determined to be a pledge of security for a loan,
however, the Depositor and the Trustee intend that the rights and obligations of the parties to the Trust Loan shall be established
pursuant to the terms of this Agreement. The Depositor and the Trustee also intend and agree that, in such event, (i) this Agreement
shall constitute a security agreement under applicable law, (ii) the Depositor shall be deemed to have granted to the Trustee (in
such capacity) a first priority security interest in all of the Depositor’s right, title and interest in and to the assets
constituting the Trust Fund, including the Trust Loan subject hereto from time to time, all amounts received on or with respect
to the Trust Loan after the Closing Date, all amounts held from time to time in the Collection Account, the Distribution Account,
and, if established, the Foreclosed Property Account, and all of the Depositor’s right, title and interest under the Loan
Purchase Agreement, (iii) the possession by the Custodian of the Trust Notes with respect to the Trust Loan subject hereto from
time to time and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be
deemed to be “possession by the secured party” or possession by a purchaser or person designated by such secured party
for the purpose of perfecting such security interest under applicable law, and (iv) notifications to, and acknowledgments, receipts
or confirmations from, Persons holding such property, shall be deemed to be notifications to, or acknowledgments, receipts or confirmations
from, securities intermediaries, bailees or agents (as applicable) of the Trustee for the purpose of perfecting such security interest
under applicable law.

 

2.2.          
Acceptance by the Trustee and the Custodian. (a)  By its execution and delivery of this Agreement, the
Trustee acknowledges the assignment to it of the Trust Loan in good faith without notice of adverse claims and the Custodian declares
that it holds and will hold or will cause to be held such documents as are delivered to it constituting the Mortgage File (to the
extent the documents constituting the Mortgage File are actually delivered to it) in trust,

 

    -69-

     

    

 

upon
the conditions herein set forth, for the use and benefit of all present and future Certificateholders and the Companion Loan Holders.

 

(b)          
The execution and delivery of this Agreement by the Custodian shall constitute certification by the Custodian that with
respect to the Trust Loan (i) the original Trust Notes specified in clause (A) of the definition of “Mortgage File”
and all allonges thereto, if any, have been received by the Custodian; and (ii) such original Trust Notes have been reviewed
by the Custodian and (A) appears regular on its face (handwritten additions, changes or corrections shall not constitute irregularities
if initialed by the Borrower), (B) appears to have been executed and (C) purports to relate to the Trust Loan. The Custodian
agrees to review or cause to be reviewed the Mortgage File within 60 days after the Closing Date, and to deliver to the Trustee,
the Depositor, the Directing Holder, the Companion Loan Holders, the Loan Seller, the Servicer and the Special Servicer a Trust
Receipt and Certification in the form of Exhibit N attached hereto certifying, subject to any exceptions found by it in
such review, that (A) all documents referred to in Section 2.1(b) have been received, and (B) all documents
have been executed, appear on their face to be what they purport to be, purport to be recorded or filed (as applicable) and have
not been torn, mutilated or otherwise defaced, and appear on their faces to relate to the Whole Loan. The Custodian shall have
no responsibility for reviewing the Mortgage File except as expressly set forth in this Section 2.2(b). The Custodian
shall be under no duty or obligation to inspect, review, or examine any such documents, instruments or certificates to independently
determine that they are valid, genuine, enforceable, legally sufficient, duly authorized, or appropriate for the represented purpose,
whether the text of any assignment or endorsement is in proper or recordable form (except to determine if the endorsement conforms
to the requirements of Section 2.1(b)), whether any document has been recorded in accordance with the requirements
of any applicable jurisdiction, to independently determine that any document has actually been filed or recorded in the appropriate
office, that any document is other than what it purports to be on its face, or whether the title insurance policies relate to the
Property.

 

(c)          
Upon the first anniversary of the Closing Date, the Custodian shall deliver to the Trustee, the Depositor, the Loan Seller,
the Servicer and the Special Servicer a Final Trust Receipt in the form of Exhibit O attached hereto along with a final
exception report as to any remaining documents that are not in the Mortgage File, whereupon, within 90 days, the Servicer shall
either (i) cause the Loan Seller to cure such document deficiency; or (ii) use commercially reasonable efforts to cause
the Loan Seller to repurchase the Trust Loan pursuant to the Loan Purchase Agreement if such exception is a Material Document Defect.
The Trust’s sole remedy against the Loan Seller in connection with a Material Document Defect is to enforce the repurchase
claim in accordance with the provisions of the Loan Purchase Agreement. The Servicer shall be reimbursed for any costs, fees (including
attorney fees) and expenses incurred by it in connection with its obligations related to such enforcement by the Loan Seller, or
if the Loan Seller prevails in such enforcement action, by the Trust Fund.

 

(d)          
The Custodian’s review of the Mortgage Files and its certification with respect thereto shall not be deemed to constitute
“due diligence services” or a “third party due diligence report” as such terms are defined in Rule 17g-10
and 15Ga-2, respectively, promulgated by the Commission pursuant to the Exchange Act.

 

    -70-

     

    

 

(e)          
If the Servicer or the Special Servicer (i) receives a Repurchase Request (the receiving Servicer or Special Servicer,
as applicable, 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 such a Repurchase Request is forwarded
to the Servicer or Special Servicer by another party hereto), then the Repurchase Request Recipient shall deliver notice of such
Repurchase Request or withdrawal of a Repurchase Request (each, a “Rule 15Ga-1 Notice”) to the Certificate
Administrator, the Depositor and the Loan Seller, in each case within ten Business Days from such party’s receipt thereof.
Each Rule 15Ga-1 Notice may be delivered by electronic means.

 

Each Rule 15Ga-1 Notice
shall include (i) the identity of the Trust Loan, (ii) the date the Repurchase Request is received or the date any withdrawal
of the Repurchase Request is received, as applicable and (iii) in the case of a Repurchase Request, (A) the identity of the Person
making such Repurchase Request, and (B) if known, the basis for the Repurchase Request (as asserted in the Repurchase Request).

 

A Repurchase Request Recipient
shall not be required to provide any information in a Rule 15Ga-1 Notice protected by the attorney-client privilege or attorney
work product doctrines. The Loan Purchase Agreement will provide that (i) any Rule 15Ga-1 Notice provided pursuant to
this Section 2.2(d) is so provided only to assist the Loan Seller 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 2.2(d) 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 Loan Purchase Agreement, including
with respect to any Repurchase Request that is the subject of a Rule 15Ga-1 Notice.

 

In the event that the Depositor,
the Trustee or the Certificate Administrator receives a Repurchase Request or a withdrawal of a Repurchase Request, such party
shall promptly forward or otherwise provide written notice of such Repurchase Request or withdrawal of a Repurchase Request, as
the case may be, to the Servicer or, while a Special Servicing Loan Event has occurred and is continuing, to the Special Servicer,
and include the following statement in the related correspondence: “This is a “[Repurchase Request]/[withdrawal of
a Repurchase Request]” under Section 2.2 of the Trust and Servicing Agreement relating to the Natixis Commercial
Mortgage Securities Trust 2017-75B, Commercial Mortgage Pass-Through Certificates, Series 2017-75B requiring action by you as the
“Repurchase Request Recipient” thereunder.” Upon receipt of such Repurchase Request or withdrawal of a Repurchase
Request by the Servicer or the Special Servicer, as applicable pursuant to the prior sentence, such party shall be deemed to be
the Repurchase Request Recipient in respect of such Repurchase Request or withdrawal of a Repurchase Request, as the case may be,
and such party shall comply with the procedures set forth in this Section 2.2(d) with respect to such Repurchase Request.

 

If the Depositor, the Trustee
or the Certificate Administrator receives notice or has knowledge of a withdrawal of a Repurchase Request of which notice has been
previously received or given, and such notice was not received from or copied to the Servicer or the Special

 

    -71-

     

    

 

Servicer,
then such party shall promptly give notice of such withdrawal to the Servicer or the Special Servicer, as applicable.

2.11.       
Grantor Trust Reporting. (a) The parties intend that the portion of the Trust Fund constituting the Grantor
Trust shall constitute, and that the affairs of the Grantor Trust shall be conducted so as to qualify such portion as, a “grantor
trust” under subpart E, part I of subchapter J of the Code, and the provisions hereof shall be interpreted consistently
with this intention. In furtherance of such intention, neither the Trustee nor the Certificate Administrator shall have the power
to vary the investment of the Certificateholders in the Grantor Trust so as to improve their rate of return. The Certificate Administrator
shall prepare or cause to be prepared, submit to the Trustee for execution (and the Trustee shall timely execute and timely return
to the Certificate Administrator) and timely file all Tax Returns in respect of the Grantor Trust. In addition, the Certificate
Administrator shall (A) file, or cause to be filed, Internal Revenue Service Form 1041, Form 1099 or such other
form as may be applicable with the Internal Revenue Service with copies of the statements in the following clause and (B) furnish,
or cause to be furnished, to the Certificateholders, their allocable share of income and expense with respect to the related Specific
Grantor Trust Assets in the time or times and in the manner required by the Code.

 

(b)          
The Grantor Trust will be treated as a WHFIT that is a WHMT. The Certificate Administrator will report as required under
the WHFIT Regulations to the extent such information as is reasonably necessary to enable the Certificate Administrator to do so
is provided to the Certificate Administrator on a timely basis. The Certificate Administrator is hereby directed to assume that
DTC is the only “middleman” as defined by the WHFIT Regulations unless the Depositor provides the Certificate Administrator
with the identities of other “middlemen” that are Certificateholders. The Certificate Administrator shall be entitled
to rely on the first sentence of this Section 2.11(b) and shall be entitled to indemnification in accordance with the terms
of this Agreement in the event that the Internal Revenue Service makes a determination that the first sentence of this paragraph
is incorrect.

 

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

 

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

Servicer to Act as the Servicer; Special Servicer to Act as the Special Servicer. The Servicer and the Special Servicer,
each as an independent contractor, shall service and administer the Whole Loan and administer any Foreclosed Property solely on
behalf of the Trust Fund and the Companion Loan Holders, in the best interest of, and for the benefit of, all the Certificateholders
and the Companion Loan Holders, as a collective whole as if such Certificateholders and the Companion Loan Holders constituted
one lender (taking into account the relative subordination of the Trust A-B Note and the Non-Trust B Note) (as determined by the
Servicer or the Special Servicer, as applicable, in the exercise of its good faith and reasonable judgment), in accordance with
applicable law (including the REMIC Provisions), the terms of this Agreement and the terms of the Loan Documents and the Co-Lender
Agreement and, to the extent consistent with the foregoing, the following standards: (i) (a) in the same manner in which
and with the same care, skill, prudence and diligence with which the Servicer or the Special Servicer, as applicable, services
and administers similar loans and manages foreclosed or other similarly situated properties for third parties, giving due consideration
to customary and usual standards of practice of prudent institutional commercial mortgage lenders in servicing their own loans,
or (b) with the care, skill, prudence and diligence the Servicer or the Special Servicer, as applicable, uses for loans which
it owns or for foreclosed or other similarly situated properties which it owns and manages, whichever is higher; (ii) with
a view to the timely collection of (a) all scheduled payments of principal and interest under the Whole Loan or, if the Whole
Loan comes into and, with respect to the Special Servicer only, continues in default and if no satisfactory arrangements can be
made for the collection of the delinquent payments, the maximization of the recovery on the Whole Loan to the Certificateholders
and the Companion Loan Holders (as a collective whole, as if the Certificateholders and the Companion Loan Holders constituted
a single lender)(taking into consideration the relative subordination of the Trust A-B Note and the Non-Trust B Note) on a net
present value basis and (b) the Borrower Reimbursable Trust Fund Expenses and other amounts due under the Whole Loan and (iii) without
regard to:

 

(A)           
any relationship that the Servicer or the Special Servicer or any affiliate thereof may have with the Borrower, the Mezzanine
Lender, the Loan Seller, any Companion Loan Holder or any of their respective affiliates;

 

(B)            
the ownership of any Certificate or any interest in the Companion Loan or the Mezzanine Loan by the Servicer or the Special
Servicer or by any affiliate thereof;

 

(C)            
in the case of the Servicer, its obligation to make Advances;

 

(D)           
the right of the Servicer or the Special Servicer or any affiliate thereof to receive reimbursement of costs, compensation
or other fees (other than Advances), or the sufficiency of any compensation payable to it under this Agreement or with respect
to any particular transaction; or

 

(E)            
the ownership, servicing or management for others of any other mortgage loans or mortgaged property by the Servicer or the
Special Servicer.

 

    -79-

     

    

 

Subject to the above-described
servicing standards (hereinafter referred to as “Accepted Servicing Practices”) and the terms of this Agreement
and of the Loan Documents, the Servicer and the Special Servicer each shall have full power and authority, acting alone and/or
through one or more sub-servicers as provided in Section 3.2, to do or cause to be done any and all things in connection
with such servicing and administration which it may deem necessary or desirable. The Servicer and the Special Servicer shall service
and administer the Whole Loan in accordance with applicable state and federal law. At the written request of the Servicer or the
Special Servicer, as applicable, accompanied by the form of power of attorney, as set out in Exhibit Q, or other documents being
requested, the Trustee shall furnish to the Servicer or the Special Servicer any powers of attorney and other documents necessary
or appropriate to enable such Servicer or the Special Servicer to carry out its servicing and administrative duties hereunder,
and the Trustee shall not be held responsible (and shall be indemnified by the Servicer or the Special Servicer) for any negligence
or misuse by the Servicer or the Special Servicer in its uses of any such powers of attorney or other document. Notwithstanding
anything contained herein to the contrary, the Servicer and the Special Servicer shall not without the Trustee’s and the
Certificate Administrator’s, as applicable, prior written consent: (i) initiate any action, suit or proceeding solely
under the Trustee’s or the Certificate Administrator’s name without indicating the representative capacity of the Servicer
or the Special Servicer, as applicable, or (ii) take any action with the intent to, and which actually does cause, the Trustee
or the Certificate Administrator to be registered to do business in any state.

 

The liability of each of the
Servicer and the Special Servicer, as applicable, for actions and omissions in its capacity as Servicer and the Special Servicer,
respectively, hereunder is limited as provided herein (including, without limitation, pursuant to Section 6.3). Nothing
contained in this Agreement shall be construed as an express or implied guarantee by the Servicer or the Special Servicer of the
collectibility of the Whole Loan.

 

3.2.          
Sub-Servicing Agreements. (a)   Each of the Servicer and the Special Servicer, at its own expense without
a right of reimbursement under this Agreement or otherwise, may enter into sub-servicing agreements with sub-servicers for the
servicing and administration of the Whole Loan, provided that (i) any such sub-servicing agreement shall be upon such
terms and conditions as are not inconsistent with this Agreement and as the Servicer or Special Servicer, as applicable, and the
sub-servicer have agreed, (ii) no sub-servicer retained by the Servicer or Special Servicer, as applicable, shall grant any
modification, waiver, or amendment to the Loan Documents without the approval of the Servicer or Special Servicer, as applicable,
and (iii) any such sub-servicer shall be precluded from participating in servicing activities relating to any foreclosure proceedings.
References in this Agreement to actions taken or to be taken, and limitations on actions permitted to be taken, by the Servicer
or Special Servicer, as applicable, in servicing the Whole Loan include actions taken or to be taken by a sub-servicer on behalf
of the Servicer or Special Servicer, as applicable. Each sub-servicer shall be (i) authorized to transact business and licensed
in the applicable state(s), if, and to the extent, required by applicable law to enable the sub-servicer to perform its obligations
under the applicable sub-servicing agreement, and (ii) qualified to perform its obligations under the applicable sub-servicing
agreement. For purposes of this Agreement, the Servicer or Special Servicer, as applicable, shall be deemed to have received any
amount when the sub-servicer receives such amount, irrespective of whether such amount is remitted to the Servicer or Special Servicer,
as applicable, for deposit in the Collection Account, the Senior Companion Loan

 

    -80-

     

    

 

Account,
any Cash Management Account, any Reserve Account or the Distribution Account, and actions taken by the sub-servicer shall be deemed
to be actions of the Servicer or Special Servicer, as applicable. The Servicer or Special Servicer, as applicable, shall notify
the Trustee, the Certificate Administrator, the Borrower, the Companion Loan Holders and the Depositor in writing promptly upon
the appointment of any sub-servicer and promptly furnish the Trustee and the Certificate Administrator, upon its request, with
a copy of the sub-servicing agreement. No sub-servicer shall be permitted to enter into any sub-servicing agreement with other
sub-servicers without the prior written consent of the Servicer or Special Servicer, as applicable.

 

(b)          
Notwithstanding any sub-servicing agreement, the Servicer or Special Servicer, as applicable, shall remain obligated and
liable to the Trustee and the Certificateholders for the servicing and administering of the Whole Loan in accordance with the provisions
of Section 3.1 without diminution of such obligation or liability by virtue of such sub-servicing agreement, or by
virtue of indemnification from a sub-servicer, and to the same extent and under the same terms and conditions as if the Servicer
or Special Servicer, as applicable, alone were servicing and administering the Whole Loan.

 

(c)          
Any sub-servicing agreement entered into by the Servicer or Special Servicer, as applicable, shall provide that it may be
assumed or terminated by (i) the Trustee if the Trustee has assumed the duties of the Servicer or Special Servicer, as applicable,
or if the Servicer or Special Servicer, as applicable, is otherwise terminated pursuant to the terms of this Agreement, or (ii) a
successor Servicer or Special Servicer, as applicable, if such successor Servicer or Special Servicer, as applicable, has assumed
the duties of the Servicer or Special Servicer, as applicable, without cost or obligation to the Trustee, the Certificate Administrator,
the successor Servicer or Special Servicer, as applicable, the Trust, the Companion Loan Holders or the Trust Fund.

 

(d)          
Any sub-servicing agreement, and any other transactions or services relating to the Whole Loan involving a sub-servicer,
shall be deemed to be between the Servicer or Special Servicer, as applicable, and such sub-servicer alone, and the Trustee, the
Certificate Administrator, the Depositor, the Trust, the Certificateholders and the Companion Loan Holders shall not be deemed
parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the sub-servicer, and no provision
herein shall be construed so as to require the Trust, the Trustee, the Certificate Administrator or the Depositor to indemnify
any such sub-servicer. The Servicer or Special Servicer, as applicable, is permitted, at its own expense, or to the extent that
a particular expense is provided herein to be an Advance or an expense of the Trust, at the expense of the Trust, to utilize other
agents or attorneys typically used by servicers of mortgage loans underlying commercial mortgage-backed securities in performing
its obligations under this Agreement.

 

(e)          
Notwithstanding anything herein, each of the initial Servicer and the initial Special Servicer may delegate certain of its
duties and obligations hereunder to an Affiliate of the Servicer or Special Servicer, as applicable. Such delegation shall not
be considered a sub-servicing agreement hereunder, and the requirements and obligations set forth herein applicable to sub-servicing
agreements, sub-servicers or Servicing Function Participants shall not be applicable to such arrangement. Notwithstanding any such
delegation, the Servicer and the Special Servicer shall remain obligated and liable for the performance of their respective

 

    -81-

     

    

 

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 each alone were servicing and administering the Whole Loan as required hereby. Furthermore, each of the initial Servicer
and the initial Special Servicer may contract with third party vendors or sub-contractors for the performance of limited functions
such as the performance of inspections or conduction of appraisals and such contracts shall not be considered a sub-servicing
agreement hereunder, and the requirements and obligations set forth herein applicable to sub-servicing agreements and sub-servicers
shall not be applicable to such arrangement; provided that the Servicer and the Special Servicer shall remain obligated and liable
for the performance of their 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 each alone were performing such functions as required hereby; provided
further that any engagement of a party that performs any activity that addresses the Applicable Servicing Criteria shall be considered
a Servicing Function Participant and the requirements and obligations set forth herein applicable to Servicing Function Participants
shall apply.

 

(f)          
The parties hereto acknowledge that the Whole Loan is subject to the terms and conditions of the Co-Lender Agreement and
recognize the respective rights and obligations of the Trust, as holder of the Trust Loan, and of the Companion Loan Holders, as
holders of the Companion Loans, under the Co-Lender Agreement, including: (i) with respect to the allocation of collections on

any conflict between this Agreement and the Co-Lender Agreement, the terms of the Co-Lender Agreement shall control with respect
to the Whole Loan.

 

3.3.         
Cash Management Account. A Cash Management Account has been or shall be established pursuant to the terms of the
Loan Agreement. The Servicer shall exercise and enforce the rights of the Trust Fund with respect to the Cash Management Accounts
under the Loan Agreement in accordance with Accepted Servicing Practices.

of the location and account number of the Collection Account and shall notify the Certificate Administrator in writing prior to
any subsequent change thereof.

 

(c)          
On or prior to each Remittance Date (or such other date as specified below or on which funds are available for such purpose
as specified below), prior to the remittance of Available Funds to the Certificate Administrator for deposit in the Distribution
Account pursuant to Section 3.5, the Servicer shall make withdrawals from the Collection Account (which withdrawals

is paid out of other amounts on deposit in the Collection Account;

 

(iii)         
concurrently, to pay the Servicing Fee to the Servicer (or with respect to the Excess Servicing Fee Rights, to pay any Excess

made by each and not previously reimbursed from late payments received during the applicable period on the Whole Loan, Liquidation
Proceeds, Foreclosure Proceeds and other collections on the Whole Loan; provided that any Advance which has been determined
to be a Nonrecoverable Advance shall be reimbursed pursuant to clause (ii) above and (B) unpaid interest on such
Advances at the Advance Rate (subject to the same order of priority as between the payment of Advances with respect to the A Notes
and the Trust A-B Note as provided in clause (ii) above); provided, however, that interest on Advances shall
be paid first out of Default Interest or late payment charges collected in the related Collection Period before such interest on
Advances is paid out of other amounts on deposit in the Collection Account;

 

(vi)          
to reimburse the Trustee, the Certificate Administrator, the Servicer and the Special Servicer, in that order, for expenses
incurred by them in connection with the liquidation of the Whole Loan or Foreclosed Property, and not otherwise covered and paid

(vii)         
(A) to pay to the Servicer, as additional compensation, to the extent actually received from the Borrower, any payments

pursuant to this clause (vii) solely for the purpose of determining the Available Funds Reduction Amount in connection
with the calculation of Available Funds for the related Distribution Date; and (B) to pay to the Special Servicer, as additional
compensation, (i) Additional Special Servicing Compensation and (ii) any income earned on the investment of funds deposited in

(viii)         to pay or reimburse the Trustee, the Certificate Administrator, the Servicer, the Special Servicer and the Depositor, in
that order, for any indemnities, expenses and other amounts then due and payable or reimbursable to each pursuant to the terms
of this Agreement, including any Trust Fund Expenses, in each case, not previously paid or reimbursed pursuant to the preceding
clauses;

 

(ix)          
to deposit into the Senior Companion Loan Account any portion of such collections that are required to be distributed to
the Companion Loan Holders in respect of the Companion Loans pursuant to the Co-Lender Agreement;

 

(x)           
to the extent not previously paid or advanced, to pay to the Certificate Administrator (or set aside for eventual payment)
any and all taxes imposed on the Trust or the Trust Fund by federal or state governmental authorities; provided, that if
such taxes are the result of the Depositor’s, Servicer’s, Special Servicer’s, the Certificate Administrator’s
or Trustee’s, as applicable, negligence, bad faith, fraud or willful misconduct, such amounts may not be withdrawn from the
Collection Account, but will be paid by such party that was negligent, acted in bad faith or fraudulently or engaged in willful
misconduct pursuant to Sections 6.3, 6.6, 8.1, 8.3 and 8.12;

 

(xi)          
to pay (or set aside for eventual payment) any and all taxes imposed on the Lower-Tier REMIC or Upper-Tier REMIC by federal
or state governmental authorities to the extent such taxes have not been paid pursuant to Section 12.1(k); and

 

(xii)         
to pay the CREFC® License Fee to CREFC®, to the extent funds are available following the withdrawal
of the amounts described in clauses (ii)-(xi) above.

 

For the avoidance of doubt, payments
or collections allocable to the Trust Loan shall be received from or made to the Collection Account and payments or collections
allocable to the Junior Companion Loan shall be received from or made to the Senior Companion Loan Account.

 

Notwithstanding the foregoing,
with respect to any Remittance Date, in no event shall the Servicer be permitted to make a withdrawal pursuant to clauses 3.4(c)(iii),
(iv), (v), (vi), (viii) or (xii) if, as a result of such withdrawal, the amount on deposit in
the Collection Account after giving effect to such withdrawal would be less than the Required Advance Amount; provided that
the Servicer shall be permitted to make withdrawals in the order of priority specified above up to the amount on deposit in the
Collection Account that would result in funds equaling or exceeding the Required Advance Amount remaining in the Collection Account.
Notwithstanding the foregoing, such withdrawal limitations shall not apply upon (1) the final liquidation of the Whole Loan
and/or the Property, (2) the final payment of the Whole Loan and release of the Mortgage or (3) the determination that any
Advance that would increase the currently unreimbursed Advances in the aggregate would be a Nonrecoverable Advance. For the avoidance
of doubt, in no event shall the Servicer be permitted to apply any portion of collections that are required to be distributed to
the Companion Loan Holders in respect of the Companion Loans pursuant to the terms of the Co-Lender Agreement to pay or reimburse
any CREFC® Intellectual Property Royalty License Fee, the Certificate Administrator Fee or any

 

    -86-

     

    

 

Trust
Fund Expenses that are not related to the servicing and administration of the Trust Loan or the Property.

 

On the Remittance Date, the Servicer
shall pay to the Certificate Administrator (on behalf of itself and the Trustee) and advance or pay to the Special Servicer, if
applicable, from the Collection Account as provided above amounts permitted to be paid to the Special Servicer, the Certificate
Administrator and the Trustee, as applicable, therefrom, upon receipt on or prior to the Determination Date of certificates of
a Servicing Officer of the Special Servicer or a Responsible Officer of the Certificate Administrator and the Trustee, as applicable,
describing the item and amount to which the Special Servicer, the Certificate Administrator and the Trustee, respectively, are
entitled. The Servicer may rely conclusively on any such certificate, shall have no duty to recalculate the amounts stated therein
and shall have no liability if the amount paid in reliance thereon is an amount to which the Special Servicer, the Certificate
Administrator or the Trustee, as applicable, is not entitled.

 

(d)          
The Certificate Administrator shall establish and maintain a reserve account (which may be a subaccount of the Distribution
Account) (the “Interest Reserve Account”) on behalf of the Trustee and for the benefit of the holders of the
Certificates. Funds on deposit in the Interest Reserve Account shall be uninvested. On each Distribution Date occurring in any
February and on any Distribution Date occurring in any January which occurs in a year that is not a leap year (unless, in either
case, such Distribution Date is the final Distribution Date), the Certificate Administrator shall deposit into the Interest Reserve
Account an amount equal to one day’s net interest collected on the principal balance of the Trust Loan as of the Payment
Date occurring in the month preceding the month in which such Distribution Date occurs at the related Mortgage Rate (net of the
Servicing Fee, the CREFC® License Fee and the Certificate Administrator Fee payable therefrom) to the extent a full
Monthly Payment or Monthly Payment Advance is made in respect thereof (all amounts so deposited in any consecutive January and
February, “Withheld Amounts”). On each Remittance 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 and February, if any, and transfer such amounts into the Distribution
Account.

 

(e)          
On each Remittance Date or, following the securitization of any Senior Companion Loan, on or prior to the day that is the
earlier of (A) the Remittance Date and (B) the Business Day following the “determination date” (or any term substantially
similar thereto), as such term is defined in the related Senior Companion Loan Pooling and Servicing Agreement as long as such
determination date is no earlier than the 1st day of the calendar month, the Servicer shall distribute all funds in the Collection
Account (or any sub-account thereof established for the benefit of the Senior Companion Loan Account) to the Senior Companion Loan
Holder in accordance with the amounts due to such holder under the terms of the Co-Lender Agreement.

 

3.5.         
Distribution Account. (a) The Certificate Administrator shall establish and maintain on behalf of the Trustee and
for the benefit of the Certificateholders a segregated non-interest bearing trust account (the “Distribution Account”),
which shall be deemed to include the Lower-Tier Distribution Account, the Upper-Tier Distribution Account and the Regular Interest
Distribution Account, which shall be subaccounts of the Distribution

 

    -87-

     

    

 

Account
for the benefit of the Certificateholders and the Trustee, as Holder of the Uncertificated Lower-Tier Interests and the Regular
Interests (the “Lower-Tier Distribution Account”, “Upper-Tier Distribution Account” and
“Regular Interest Distribution Account”, respectively). The Distribution Account must be an Eligible Account.
On each Remittance Date, the Servicer shall transfer from the Collection Account to the Certificate Administrator for deposit
into the Distribution Account all funds remaining on deposit therein pursuant to clause (xii) of Section 3.4(c).
The Certificate Administrator shall credit the funds remitted by the Servicer from the Collection Account to the Distribution
Account. Amounts held in the Distribution Account shall be uninvested.

 

The Certificate Administrator
shall make withdrawals from the Distribution Account (i) to withdraw any amounts deposited therein in error, (ii) to deposit any
required Withheld Amounts into the Interest Reserve Account pursuant to Section 3.4(d) and (iii) to make distributions to
the Holders of the Certificates pursuant to Section 4.1.

 

(b)          
The Certificate Administrator shall make or be deemed to have made withdrawals from the Lower-Tier Distribution Account
in the following order of priority and only for the following purposes:

 

(i)           
to make deposits of the Lower-Tier Distribution Amount pursuant to Section 4.1(b) and Section 4.3(b)
into the Upper-Tier Distribution Account and to make distributions to the Holder of the Class R Certificates (in respect of
the Class LT-R Interest) pursuant to Section 4.1(b);

 

(ii)          
to withdraw amounts deposited into the Lower-Tier Distribution Account in error and pay such amounts to the Persons entitled
thereto; and

 

(iii)         
to clear and terminate the Lower-Tier Distribution Account pursuant to Section 10.2.

 

(c)           
The Certificate Administrator shall make withdrawals from the Upper-Tier Distribution Account in the following order of
priority and only for the following purposes:

 

(i)            
to withdraw amounts deposited in error;

 

(ii)          
to make deposits in the Regular Interest Distribution Account in respect in respect of amounts distributed to the Holders
of the Regular Interests and to make distributions to Holders of the Class R Certificates (in respect of the Class UT-R
Interest) on each Distribution Date pursuant to Section 4.1(a) or Sections 10.1 and 10.2 as applicable;
and

 

(iii)         
to clear and terminate the Upper-Tier Distribution Account at the termination of this Agreement pursuant to Section 10.2.

 

(d)          
The Certificate Administrator shall make withdrawals from the Regular Interest Distribution Account in the following order
of priority and only for the following purposes:

 

    -88-

     

    

 

(i)            
to withdraw amounts deposited in error;

 

(ii)           
to make distributions to Holders of the Certificates (other than the Class R Certificates) on each Distribution Date pursuant
to Section 4.1(b) or Sections 10.1 and 10.2 as applicable; and

 

(iii)          
to clear and terminate the Regular Interest Distribution Account at the termination of this Agreement pursuant to Section
10.2.

 

3.6.          
Foreclosed Property Account. The Special Servicer shall establish and maintain one or more deposit accounts (the
“Foreclosed Property Account”) for the benefit of the Certificateholders and the Companion Loan Holders in the
name of “KeyBank National Association, as Special Servicer for Wells Fargo Bank, National Association, as Trustee of Natixis
Commercial Mortgage Securities Trust 2017-75B, Commercial Mortgage Pass-Through Certificates, Series 2017-75B” related to
the Foreclosed Property, if any, held in the name of the Special Servicer for the benefit of the Trustee on behalf of the Certificateholders
and the Companion Loan Holders. The Foreclosed Property Account must be an Eligible Account maintained with an Eligible Institution.
The Special Servicer shall deposit into the Foreclosed Property Account within one Business Day of receipt all properly identified
funds collected and received in connection with the operation or ownership of such Foreclosed Property. On or before the Determination
Date, the Special Servicer shall withdraw the funds in the Foreclosed Property Account, net of certain expenses and/or reserves
(to the extent not inconsistent with the express terms hereof, the amount of such reserves to be determined in accordance with
the Special Servicer’s reasonable discretion and in accordance with Accepted Servicing Practices), and deposit them into
the Collection Account in accordance with Section 3.4(a). The Special Servicer shall notify the Certificate Administrator
in writing of the location and account number of the Foreclosed Property Account and shall notify the Certificate Administrator
in writing prior to any subsequent change thereof.

 

3.7.          
Appraisal Reductions. (a)  Within 30 days after the occurrence of an Appraisal Reduction Event with respect
to the Whole Loan, the Special Servicer shall (i) notify the Servicer, the Trustee and the Certificate Administrator and,
during any Subordinate Control Period or Subordinate Consultation Period, the Directing Holder, of such occurrence of an Appraisal
Reduction Event and (ii) order an Appraisal of the Property (provided that the Special Servicer will not be required
to obtain an Appraisal of the Property with respect to which there exists an Appraisal which is less than nine months old, unless
it has actual knowledge of a material adverse change in the market or condition or value of the Property) and no later than the
later of (a) 60 days after the Appraisal Reduction Event with respect to the Whole Loan or (b) 10 Business Days after obtaining
the final Appraisal of the Property, the Special Servicer shall determine on the basis of such Appraisal whether there exists
any Appraisal Reduction Amount and if so, give reasonably prompt notice thereof to the Companion Loan Holders. The cost of obtaining
any such Appraisal shall be paid by the Servicer as a Property Protection Advance or an Administrative Advance unless it would
constitute a Nonrecoverable Advance. Updates of any such Appraisal shall be obtained by the Special Servicer, and paid for by the
Servicer as a Property Protection Advance or an Administrative Advance every twelve months for so long as an Appraisal Reduction
Event exists, and the Appraisal Reduction Amount shall be adjusted accordingly. If required in accordance with any such adjustment,
each Class of

 

    -89-

     

    

 

Certificates
that has been notionally reduced as a result of Appraisal Reduction Amounts shall have its related Certificate Balance notionally
restored by the Certificate Administrator or the Trustee to the extent required by such adjustment of the Appraisal Reduction
Amount, and there will be a redetermination of whether a Subordinate Control Period or Subordinate Consultation Period is in effect.
Any such Appraisal obtained pursuant to this Section 3.7(a) will be delivered by the Special Servicer to the Servicer,
the 17g-5 Information Provider, the Certificate Administrator, Companion Loan Holders and, during any Subordinate Control Period
or Subordinate Consultation Period, the Directing Holder in electronic format and the Certificate Administrator shall make such
Appraisal available to Privileged Persons pursuant to Section 8.14(b). The 17g-5 Information Provider shall post such Appraisal
on the 17g-5 Information Provider’s Website pursuant to Section 8.14(b). Following notification from the Special
Servicer of any Appraisal Reduction Amount, the Servicer and the Trustee shall notify the Other Servicer and Other Trustee of
the existence of an Appraisal Reduction Event and any related Appraisal Reduction Amount. Following notification from the Special
Servicer, the Servicer and the Trustee shall be deemed to have delivered notice of any such Appraisal Reduction Event and any
related Appraisal Reduction Amount if the Servicer includes such event and/or amount in its monthly servicer statements provided
to the Other Servicer.

 

The Whole Loan will be treated
as a single mortgage loan for purposes of calculating the Appraisal Reduction Amount. Any Appraisal Reduction Amount with respect
to the Whole Loan shall be allocated first, to the Non-Trust B Note, up to the full outstanding principal balance thereof,
then, to the Trust A-B Note, up to the full outstanding principal balance thereof, and then, to the Trust A Note
and the Non-Trust A Note, on a pro rata and pari passu basis, based on their respective outstanding principal balances.

 

(b)          
While an Appraisal Reduction Amount exists, (i) the amount of any Monthly Payment Advances with respect to the Trust
Loan shall be reduced as provided in Section 3.23(a) and (ii) the existence thereof will be taken into account
for purposes of determining the Voting Rights of certain Classes of Certificates as provided in Section 3.7(c).

 

(c)          
The Certificate Balance of each of the Sequential Pay Certificates shall be notionally reduced (solely for purposes of determining
(i) the Voting Rights of the related Classes and (ii) whether a Subordinate Control Period or Subordinate Consultation Period is
in effect) on any Distribution Date to the extent of the Appraisal Reduction Amount allocated to such Class on such Distribution
Date. The Appraisal Reduction Amount for any Distribution Date shall be applied to notionally reduce the Certificate Balances of
the Certificates in the following order of priority: first, to the Class E Certificates, second, to the Class D
Certificates; third, to the Class C Certificates; and fourth, to the Class B Certificates (provided in each
case that no Certificate Balance in respect of any such Class may be notionally reduced below zero). Appraisal Reduction Amounts
shall not be applied to notionally reduce the Certificate Balance of any Class A Certificate.

 

Any such allocations of Appraisal
Reduction Amounts to:

 

(i)            the Class A Regular Interest shall be further allocated to the Class A Certificates, the Class V1-A Certificates and the
Class V2 Certificates, pro rata in

 

    -90-

     

    

 

proportion
to the Class A Percentage Interest, the Class V1-A Percentage Interest and the Class V2 Percentage Interest, respectively;

 

(ii)            the Class B Regular Interest shall be further allocated to the Class B Certificates, the Class V1-B Certificates and the
Class V2 Certificates, pro rata in proportion to the Class B Percentage Interest, the Class V1-B Percentage Interest and
the Class V2 Percentage Interest, respectively;

 

(iii)           the Class C Regular Interest shall be further allocated to the Class C Certificates, the Class V1-C Certificates and the
Class V2 Certificates, pro rata in proportion to the Class C Percentage Interest, the Class V1-C Percentage Interest and
the Class V2 Percentage Interest, respectively;

 

(iv)           the Class D Regular Interest shall be further allocated to the Class D Certificates, the Class V1-D Certificates and the
Class V2 Certificates, pro rata in proportion to the Class D Percentage Interest, the Class V1-D Percentage Interest and
the Class V2 Percentage Interest, respectively; and

 

(v)            the Class E Regular Interest shall be further allocated to the Class E Certificates, the Class V1-E Certificates and the
Class V2 Certificates, pro rata in proportion to the Class E Percentage Interest, the Class V1-E Percentage Interest and
the Class V2 Percentage Interest, respectively.

 

(d)          
 In the event that a portion(s) of one or more Monthly Payment Advances with respect to the Trust Loan was reduced as a result
of an Appraisal Reduction Event, the amount of the Net Liquidation Proceeds to be applied to interest shall be reduced by the aggregate
amount of such reductions and the portion of such Net Liquidation Proceeds to be applied to principal shall be increased by such
amount, and if the amounts of the Net Liquidation Proceeds to be applied to principal have been applied to pay the principal of
the Trust Loan in full, any remaining Net Liquidation Proceeds shall then be applied to pay any remaining accrued and unpaid interest
on the Trust Loan in accordance with Section 1.3.

 

(e)          
If (i) an Appraisal Reduction Event has occurred, (ii) either (A) no Appraisal or update of the Appraisal has been obtained
or conducted with respect to the Property or Foreclosed Property, as the case may be, during the 12-month period prior to the date
of such Appraisal Reduction Event or (B) a material change in the circumstances surrounding the Property or Foreclosed Property,
as the case may be, has occurred since the date of the most recent Appraisal that would materially and adversely affect the value
of the Property or Foreclosed Property, as the case may be, and (iii) no new final Appraisal has been obtained or conducted for
the Property or Foreclosed Property, as the case may be, within 60 days after the Appraisal Reduction Event has occurred, then
(x) until the new Appraisal is conducted, the Appraisal Reduction Amount for the Whole Loan shall be equal to 25% of the Loan Principal
Balance for the Whole Loan, and (y) upon receipt or performance of the new Appraisal by the Special Servicer, the Appraisal Reduction
Amount for the Property or Foreclosed Property, as the case may be, shall be recalculated in accordance with the definition of
Appraisal Reduction Amount. Notwithstanding the foregoing, solely for purposes of determining whether a Subordinate Control Period
or a Subordinate Consultation Period is then in effect or the

 

    -91-

     

    

 

allocation
of Voting Rights for certain purposes, deemed Appraisal Reduction Amounts imposed pursuant to clause (x) of the preceding
sentence will not be allocated to any Class of Certificates; provided, however, this sentence shall not affect in
any manner the effect of Appraisal Reduction Amounts based upon anything other than such clause (x), including when the
related Appraisals are received.

 

With respect to any Appraisal
Reduction Amount calculated for purposes of determining an Appraisal Reduction Event, the appraised value (as determined by an
updated Appraisal) of the Property securing the Whole Loan will be determined on an “as-is” basis, based upon the current
physical condition, use and zoning of the Property as of the date of the Appraisal.

 

If the Certificate Balance of
the Class E Certificates (taking into account the application of any Appraisal Reduction Amounts to notionally reduce the Certificate
Balance of such Class) has been reduced to less than 25% of its Initial Certificate Balance, such Class will be referred to as
the “Appraised-Out Class”. The Holders of the majority (by Certificate Balance) of the Appraised-Out Class shall
have the right, at their sole expense, to require the Special Servicer to order a second Appraisal of the Property (such Holders,
the “Requesting Holders”). The Special Servicer shall use its commercially reasonable efforts to ensure that
such Appraisal is delivered within 60 days from receipt of the Requesting Holders’ written request and shall ensure
that such Appraisal is prepared by an Independent Appraiser).

 

In addition, if subsequent to
the Class E Certificates becoming an Appraised-Out Class there is a material change with respect to the Property related to the
Appraisal Reduction Amounts that caused such Class to become an Appraised-Out Class, the Requesting Holders will have the right
to request, in writing, that the Special Servicer obtain an additional Appraisal, which request shall set forth the Requesting
Holder’s belief of what constitutes a material change to the Property (including any related documentation). The costs of
obtaining such additional Appraisal will be paid by the Requesting Holders. Subject to the Special Servicer’s confirmation,
determined in accordance with Accepted Servicing Practices, that there has been a change with respect to the Property and such
change was material, the Special Servicer shall order another Appraisal from an Independent Appraiser, the identity of which shall
be determined by the Special Servicer in accordance with Accepted Servicing Practices (provided that such Independent Appraiser
may not be the same Independent Appraiser that provided the Appraisal in respect of which the Requesting Holders are requesting
the Special Servicer to obtain an additional Appraisal and provided further that the Holders of an Appraised-Out Class may
require the Special Servicer to order an additional Appraisal no more than once in any nine-month period). Appraisals that are
permitted to be requested by any Appraised-Out Class shall be in addition to any Appraisals that the Special Servicer may otherwise
be required to obtain in accordance with Accepted Servicing Practices upon the occurrence of such material change or that the Special
Servicer is otherwise required or permitted to order under this Agreement without regard to any Appraisal requests made by any
Requesting Holder.

 

Upon receipt of any supplemental
Appraisal pursuant to the two preceding paragraphs, the Special Servicer shall recalculate such Appraisal Reduction Amounts based
upon such second Appraisal. If required by any such recalculation, the applicable Appraised-Out Class shall be reinstated as the
Controlling Class and each other Appraised-Out Class shall, if

 

    -92-

     

    

 

applicable,
have its related Certificate Balance notionally restored to the extent required by such recalculation of the Appraisal Reduction
Amounts.

 

Any Appraised-Out Class for which
the Requesting Holders are challenging the Special Servicer’s Appraisal Reduction Amounts determination may not exercise
any rights of the related Controlling Class until such time, if any, as such Class is reinstated as the Controlling Class.

 

In addition, the Special Servicer
shall comply with the terms of the Co-Lender Agreement with respect to the rights of a Companion Loan Holder to request or obtain
additional Appraisals and to request recalculations of the Appraisal Reduction Amounts.

 

3.8.         
Investment of Funds in the Collection Account, the Senior Companion Loan Account and the Foreclosed Property Account.
(a)  The Servicer (and, with respect to the Foreclosed Property Account, the Special Servicer) may direct any depository
institution maintaining the Collection Account, the Senior Companion Loan Account, the Foreclosed Property Account and any Reserve
Account (to the extent interest is not payable to the Borrower), respectively (each, for purposes of this Section 3.8,
an “Investment Account”), to invest the funds in such Investment Account in one or more Permitted Investments
that bear interest or are sold at a discount, and that mature, unless payable on demand, no later than the Business Day preceding
the date on which such funds are required to be withdrawn from such Investment Account pursuant to this Agreement. Any direction
by the Servicer or the Special Servicer, as applicable, to invest funds on deposit in an Investment Account shall be in writing
and shall certify that the requested investment is a Permitted Investment which matures at or prior to the time required hereby
or is payable on demand. All such Permitted Investments shall be held to maturity, unless payable on demand. Any investment of
funds in an Investment Account shall be made in the name of the Trustee (in its capacity as such) or in the name of a nominee of
the Trustee on behalf of the Trust. The Certificate Administrator shall have sole control (except with respect to investment direction,
which shall be in the control of the Servicer (or the Special Servicer, with respect to any Foreclosed Property Account) as an
independent contractor to the Trust Fund) over each such investment and any certificate or other instrument evidencing any such
investment shall be delivered directly to the Certificate Administrator or its agent (which shall initially be the Servicer or
the Special Servicer, as applicable), together with any document of transfer, if any, necessary to transfer title to such investment
to the Trustee or its nominee. The Trustee and the Certificate Administrator shall have no responsibility or liability with respect
to the investment directions of the Servicer or the Special Servicer, as applicable, or any losses resulting therefrom, whether
from Permitted Investments or otherwise. In the event amounts on deposit in an Investment Account are at any time invested in a
Permitted Investment payable on demand, the Servicer and the Special Servicer, as applicable, 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 (1) all amounts then payable thereunder and
(2) the amount required to be withdrawn on such date; and

 

(ii)          
demand payment of all amounts due thereunder promptly upon determination by the Servicer or Special Servicer, as applicable,
that such Permitted

 

    -93-

     

    

 

Investment
would not constitute a Permitted Investment in respect of funds thereafter on deposit in the related Investment Account.

 

(b)          
All net income and gain realized from investment of funds deposited in the Collection Account, the Senior Companion Loan
Account and the Reserve Accounts (to the extent not payable to the Borrower) shall be for the benefit of the Servicer in accordance
with the terms and priorities of this Agreement. All net income and gain realized from investment of funds deposited in the Foreclosed
Property Account shall be for the benefit of the Special Servicer. Any net losses on funds in the Collection Account, the Senior
Companion Loan Account, the Reserve Accounts (except in the case of any such loss with respect to a Reserve Account, to the extent
such losses are incurred on amounts invested for the benefit of the Borrower pursuant to and in accordance with the terms of the
Loan Documents) or the Foreclosed Property Account shall be reimbursed by the Servicer or the Special Servicer, as applicable,
from its own funds promptly, but in any event on or prior to the Remittance Date following the realization of such loss. Notwithstanding
the above, neither the Servicer nor the Special Servicer shall be required to deposit any loss on an investment of funds in an
Investment Account if such loss was incurred solely as a result of the insolvency of the federal or state chartered depositary
institution or trust company that holds such Investment Account so long as (i) such depositary institution or trust company
satisfied the qualifications set forth in the definition of Eligible Institution at the time such investment was made and (ii) such
loss was incurred within 30 days after the date of such insolvency, and (iii) such loss is not the result of fraud, negligence,
bad faith or willful misconduct of the Servicer or Special Servicer, as applicable.

 

(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 Servicer shall
take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate
proceedings. In the event the Servicer takes any such action, the Trust Fund shall pay or reimburse the Servicer, pursuant to Section 3.4(c),
for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by the Servicer in connection therewith.

 

(d)          
Notwithstanding the foregoing, none of the Servicer, the Special Servicer, the Certificate Administrator or the Trustee
(in its capacity as the Servicer, the Special Servicer, the Certificate Administrator or the Trustee, as the case may be) shall
cover any losses from the bankruptcy or insolvency of a depository institution holding an account described in this Section 3.8,
if (i) immediately prior to such bankruptcy or insolvency such institution was an Eligible Institution at the time of such deposit
and (ii) such loss was not the result of fraud, bad faith, negligence or willful misconduct of the Servicer, the Special Servicer,
the Certificate Administrator or the Trustee, as applicable.

 

3.9.         
Payment of Taxes, Assessments, etc. The Servicer (other than with respect to any Foreclosed Property) and the Special
Servicer (with respect to any Foreclosed Property) shall maintain accurate records with respect to the Property (or Foreclosed
Property, as the case may be) reflecting the status of taxes, assessments, charges and other similar items that are or may become
a lien on the Property (or Foreclosed Property, as the case may be) and the

 

    -94-

     

    

 

status
of insurance premiums payable in respect of insurance policies required to be maintained pursuant to Section 3.11
hereof. The Servicer shall obtain, from time to time, all bills for the payment of such items (including renewal premiums). The
Servicer shall pay (or cause to be paid) real estate taxes, insurance premiums and other similar items from funds in the applicable
Reserve Account in accordance with the Loan Agreement at such time as may be required by the Loan Documents. If the Borrower does
not make the necessary payments and/or a Loan Event of Default has occurred and amounts in the applicable Reserve Account are
insufficient to make such payments, the Servicer shall make a Property Protection Advance, subject to the determination of non-recoverability
provided in Section 3.23, from its own funds for amounts payable with respect to all such items related to the Property
when and as the same shall become due and payable. The Servicer shall ensure that the amount of funds in the applicable Reserve
Account is increased when and if applicable taxes, assessments, charges and other similar items, ground rents, leasehold rents
or insurance premiums are increased, in accordance with the terms of the Loan Agreement.

 

3.10.         Appointment of Special Servicer. (a)  KeyBank National Association is hereby appointed as the initial Special
Servicer to service the Whole Loan while a Special Servicing Loan Event has occurred and is continuing and perform the other obligations
of the Special Servicer hereunder.

 

(b)          
If there is a Special Servicer Termination Event with respect to the Special Servicer, the Special Servicer may be removed
and replaced pursuant to Sections 7.1 and 7.2. The Trustee or the Certificate Administrator, as applicable,
shall, promptly after receiving notice of any such Special Servicer Termination Event, notify the Servicer, the Trustee (in the
case of the Certificate Administrator) and the Certificate Administrator (which shall post such notice on the Certificate Administrator’s
Website in accordance with Section 8.14(b)), the Senior Companion Loan Holder and the 17g-5 Information Provider (which
shall post such notice on the 17g-5 Information Provider’s Website in accordance with Section 8.14(b). The appointment
of any such successor Special Servicer shall not relieve the Servicer or the Trustee of their respective obligations to make Advances
as set forth herein; provided, however, the initial Special Servicer specified above shall not be liable for any
actions or any inaction of such successor Special Servicer. No termination fee shall be payable to the terminated Special Servicer.
No termination of the Special Servicer and appointment of a successor Special Servicer shall be effective until the successor Special
Servicer has assumed all of its responsibilities, duties and liabilities hereunder in writing and a Rating Agency Confirmation
with respect to such appointment has been delivered to the Trustee. Any successor Special Servicer shall be deemed to make the
representations and warranties provided for in Section 2.5(a) mutatis mutandis as of the date of its succession.
The terminated Special Servicer shall retain all rights accruing to it under this Agreement, including the right to receive fees
accrued prior to its termination and other amounts payable to it (including indemnification payments).

 

(c)          
Upon determining that a Special Servicing Loan Event has occurred and is continuing with respect to the Whole Loan, the
Servicer shall immediately give notice thereof to the Special Servicer, the Trustee, and the Certificate Administrator and the
Companion Loan Holders and the Servicer shall use its reasonable efforts to provide the Special Servicer with all information,
documents (but excluding the original documents constituting the Mortgage File)

 

    -95-

     

    

 

and
records (including records stored electronically on computer tapes, magnetic discs and the like) relating to the Whole Loan and
reasonably requested by the Special Servicer to enable it to assume its duties hereunder with respect thereto. The Servicer shall
use its reasonable efforts to comply with the preceding sentence within five Business Days of the date that a Special Servicing
Loan Event has occurred. The Servicer, in any event, shall continue to act as Servicer and administrator of the Whole Loan until
the Special Servicer has commenced the servicing of the Whole Loan, upon the occurrence and during the continuation of a Special
Servicing Loan Event, which commencement shall occur, in the case of a Special Servicing Loan Event, upon the receipt by the Special
Servicer of the information, documents and records referred to in the preceding sentence. The Special Servicer shall instruct
the Borrower to continue to remit all payments in respect of the Whole Loan to the Servicer. The Servicer shall forward any notices
it would otherwise send to the Borrower under the Whole Loan to the Special Servicer who shall send such notice to the Borrower
while a Special Servicing Loan Event has occurred and is continuing.

 

(d)          
Upon determining that a Special Servicing Loan Event is no longer continuing with respect to the Whole Loan, the Special
Servicer shall promptly give notice thereof to the Servicer, the Trustee, the Certificate Administrator and the Companion Loan
Holders, and upon giving such notice such Special Servicing Loan Event shall cease, the Special Servicer’s obligation to
service the Whole Loan shall terminate and the obligations of the Servicer to service and administer the Whole Loan shall resume
and the Special Servicer shall return all of the information and materials furnished to the Special Servicer pursuant to Section 3.10(c)
to the Servicer.

 

(e)          
In making a Major Decision or in servicing the Whole Loan during the continuance of a Special Servicing Loan Event, the
Special Servicer shall provide to the Certificate Administrator originals of documents entered into in connection therewith that
are required to be included within the definition of “Mortgage File” for inclusion in the Mortgage File (to
the extent such documents are in the possession of the Special Servicer) and copies of any additional Whole Loan information, including
correspondence with the Borrower, and the Special Servicer shall promptly provide copies of all of the foregoing to the Servicer
as well as copies of any related analysis or internal review prepared by or for the benefit of the Special Servicer.

 

(f)          
During any period in which a Special Servicing Loan Event is continuing with respect to the Whole Loan, on the Determination
Date, the Special Servicer shall deliver to the Servicer to the extent not included in the CREFC® Special Servicer
Loan File a written statement describing (i) the amount of all payments on account of interest received on the Whole Loan,
the amount of all payments on account of principal received on the Whole Loan, the amount of Insurance Proceeds, Condemnation Proceeds
and Net Liquidation Proceeds received, the amount of any Foreclosure Proceeds received with respect to the Property, and the amount
of net income or net loss, as determined from 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 rental income that does not constitute rents from real property with respect to,
the Foreclosed Property, in each case in accordance with Section 3.15 and (ii) such additional information relating
to the Whole Loan as the Servicer or the Certificate Administrator reasonably requests to enable it to perform its duties under
this Agreement.

 

    -96-

     

    

 

(g)           
Notwithstanding the provisions of the preceding subsection (c), the Servicer shall maintain ongoing payment records
with respect to the Whole Loan and shall provide the Special Servicer with any information reasonably required by the Special Servicer
to perform its duties under this Agreement.

 

(h)           
Within 60 days after a Special Servicing Loan Event occurs with respect to the Whole Loan, the Special Servicer shall prepare
a report (the “Asset Status Report”) for the Whole Loan and the Property and deliver such report in electronic
format to the Servicer, the Directing Holder (but only during any Subordinate Control Period or Subordinate Consultation Period),
the Risk Retention Consultation Party (for so long as it is not a Borrower Related Party), the Companion Loan Holders and to the
17g-5 Information Provider in accordance with Section 8.14(b), (who shall promptly post it to the 17g-5 Information
Provider’s Website pursuant to Section 8.14(b)). Such Asset Status Report shall set forth the following information
to the extent reasonably determinable:

 

(i)            
summary of the status of the Whole Loan and any negotiations with the Borrower;

 

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

 

(iii)          
the most current rent roll and income or operating statement available for the Property;

 

(iv)          
the Special Servicer’s recommendations on how the Whole Loan might be returned to performing status or otherwise realized
upon;

 

(v)           
the appraised value of the Property together with the assumptions used in the calculation thereof;

 

(vi)          
the status of any foreclosure actions or other proceedings undertaken with respect thereto, any proposed workouts with respect
thereto and the status of any negotiations with respect to such workouts, and an assessment of the likelihood of additional Loan
Events of Default;

 

(vii)         
a description of any proposed or taken actions;

 

(viii)        
the alternative courses of action considered by the Special Servicer in connection with the proposed or taken actions;

 

(ix)          
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; and an analysis
of whether or not taking such 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

 

    -97-

     

    

 

Servicer
made such determination and (y) the net present value calculation (including the applicable discount rate used) and all related
assumptions; and

 

(x)           
such other information as the Special Servicer deems relevant in light of the proposed action and Accepted Servicing Practices.

 

The Special Servicer shall (x) deliver
to the Certificate Administrator and 17g-5 Information Provider the Final Asset Status Report and to the Certificate Administrator
a proposed notice to Certificateholders that will include a summary of the Final Asset Status Report in an electronic format (which
shall be a brief summary of the current status of the Property, but will not include any information related to its workout strategy
with respect to the Whole Loan), and the Certificate Administrator shall post such summary on the Certificate Administrator’s
Website pursuant to Section 8.14(b) and (y) implement the Asset Status Report in the form delivered to the Certificate
Administrator. The 17g-5 Information Provider shall post the Asset Status Report on the 17g-5 Information Provider’s Website.
The Special Servicer may, from time to time, modify any Asset Status Report it has previously delivered and, following the prompt
delivery of such modified Asset Status Report to the 17g-5 Information Provider and a summary of the same to the Certificate Administrator,
and each shall post the modified Asset Status Report and summary of the Final Asset Status Report thereof to its respective website
pursuant to Section 8.14(b), shall implement such report.

 

Subject to the last paragraph
of Section 9.3(a), during any Subordinate Control Period, if within ten (10) Business Days of receiving an Asset Status
Report, the Directing Holder does not disapprove such Asset Status Report in writing, the Special Servicer shall implement the
recommended action as outlined in such Asset Status Report. If, during any Subordinate Control Period, the Directing Holder disapproves
such Asset Status Report within ten (10) Business Days of receipt and the Special Servicer has not made the determination described
below, 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 Directing Holder, the Servicer, the Trustee, the Certificate
Administrator and the 17g 5 Information Provider (which shall promptly post such revised Asset Status Report on the 17g 5 Information
Provider’s Website in accordance with Section 8.14(b)). During any Subordinate Control Period, the Special Servicer shall
revise such Asset Status Report as described above in this Section 3.10(h) until the Directing Holder shall fail to disapprove
such revised Asset Status Report in writing within ten (10) Business Days of receiving such revised Asset Status Report, until
the Directing Holder’s approval is no longer required or until the Special Servicer makes the determination described below.
Notwithstanding the foregoing, the Special Servicer (A) may, following the occurrence of an extraordinary event with respect to
the Property or the Whole Loan or, if a failure to take any such action at such time would be inconsistent with Accepted Servicing
Practices, take any action set forth in such Asset Status Report before the expiration of a ten (10) Business Day period and (B)
shall implement the action recommended in the Asset Status Report if it makes a determination in accordance with Accepted Servicing
Practices that such affirmative disapproval is not in the best interest of all the Certificateholders and the Companion Loan Holders;
provided, however, that such Asset Status Report is not intended to replace or satisfy any other specific consent
or approval right which the Directing Holder may have pursuant to Section 9.3.

 

    -98-

     

    

 

The Special Servicer shall deliver
to the Servicer, the Directing Holder (during any Subordinate Consultation Period) and the 17g-5 Information Provider (which shall
promptly post the same to the 17g-5 Information Provider’s Website) and the Companion Loan Holders a copy of each Final Asset
Status Report, in each case with reasonable promptness following the adoption thereof. The Special Servicer shall provide a summary
of such report to the Certificate Administrator, and the Certificate Administrator shall post such summary to its Internet website.

 

After the termination of any
Subordinate Control Period, the Directing Holder shall have no right to consent to any Asset Status Report under this Section
3.10(h) or otherwise direct the Servicer or Special Servicer. After the termination of any Subordinate Consultation Period,
the Directing Holder (other than in its capacity as a Certificateholder) shall have no right to receive any Asset Status Report
or otherwise consult with the Special Servicer with respect to any matter set forth therein.

 

Notwithstanding anything herein
to the contrary: (i) the Servicer and the Special Servicer shall have no right or obligation to consult with or to seek and/or
obtain consent, approval or direction from any Directing Holder prior to or after acting or making any determination (and provisions
of this Agreement requiring such consultation, consent or approval shall be of no effect) during the period following any resignation
or removal of a Directing Holder and before a replacement is selected and/or identified; and (ii) no advice, direction or objection
from or by the Directing Holder, as contemplated by Section 9.3 or pursuant to any other provision of this Agreement, as contemplated
by this Agreement, may (and the applicable Servicer or Special Servicer may ignore and act without regard to any such advice, direction
or objection that such Servicer or Special Servicer, as applicable, has determined, in its reasonable, good faith judgment, would):
(A) require or cause such Servicer or Special Servicer, as applicable, to violate applicable law, the terms of the Loan Documents
or this Agreement, including, as applicable, the Servicer’s or Special Servicer’s obligation to act in accordance with
the Accepted Servicing Practices, (B) result in an Adverse REMIC Event, (C) expose the Trust, the Depositor, the Servicer, the
Special Servicer, the Certificate Administrator, the Trustee or any of their respective Affiliates, members, managers, officers,
directors, employees or agents, to any claim, suit or liability or (D) materially expand the scope of the Servicer’s, the
Special Servicer’s, the Trustee’s or the Certificate Administrator’s responsibilities under this Agreement.

 

(i)            
During the continuance of a Special Servicing Loan Event, the Special Servicer shall have the authority to meet with the
Borrower and, subject to the rights of the Directing Holder (during any Subordinate Control Period or Subordinate Consultation
Period) take any actions consistent with Section 3.24, Accepted Servicing Practices and the most recent Asset Status
Report.

 

(j)          
  In addition, during the continuance of a Special Servicing Loan Event, on the Determination Date the Special Servicer shall
prepare and deliver to the Servicer the CREFC® Special Servicer Loan File with respect to the Whole Loan.

 

3.11.         Maintenance of Insurance and Errors and Omissions and Fidelity Coverage. (a)  The Servicer, consistent
with Accepted Servicing Practices and the Loan Documents, shall cause to be maintained by the Borrower (or if the Borrower fails
to maintain

 

    -99-

     

    

 

such
insurance in accordance with the Loan Agreement, the Servicer shall cause to be maintained to the extent such insurance is available
at commercially reasonable rates, and to the extent the Trustee on behalf of the Trust Fund and the Companion Loan Holders, as
mortgagee, has an insurable interest) insurance with respect to the Property of the types and in the amounts required to be maintained
by the Borrower under the Loan Documents. The cost of any such insurance maintained by the Servicer shall be advanced by the Servicer,
as a Property Protection Advance unless it would be a Nonrecoverable Advance. Neither the Servicer nor the Special Servicer shall
be required to maintain, and shall not cause the Borrower to be in default with respect to the failure of the Borrower to obtain,
all-risk casualty insurance which does not contain any carve-out for terrorist or similar acts, if and only if the Special Servicer
and, during any Subordinate Control Period, the Directing Holder, have determined, on an annual basis, that such insurance is
not required pursuant to the terms of the Loan Documents as in effect on the date thereof. Neither the Servicer nor the Special
Servicer shall be required to obtain terrorism insurance pursuant to this Agreement to the extent the Borrower would not be obligated
to maintain terrorism insurance under the Loan Documents as in effect on the date thereof.

 

(b)          
The Special Servicer, consistent with Accepted Servicing Practices and the Loan Documents, shall cause to be maintained
such insurance with respect to any Foreclosed Property as the Borrower is required to maintain with respect to the Property referred
to in subsection (a) of this Section 3.11 or, at the Special Servicer’s election, coverage satisfying insurance
requirements consistent with Accepted Servicing Practices. The cost of any such insurance with respect to any Foreclosed Property
shall be payable out of amounts on deposit in the Foreclosed Property Account or shall be advanced by the Servicer as a Property
Protection Advance unless such advance would be a Nonrecoverable Advance. Any such insurance (other than terrorism insurance, which
shall be maintained to the extent required under subsection (a)) that is required to be maintained with respect to a Foreclosed
Property shall only be so required to the extent such insurance is available at commercially reasonable rates. If the Special Servicer
requests the Servicer to make a Property Protection Advance in respect of the premiums due in respect of such insurance, the Servicer
shall, as soon as practicable after receipt of such request, make such Property Protection Advance unless such Advance would be
a Nonrecoverable Advance, and if the Servicer does not make such Advance, the Trustee (within 5 Business Days of its receipt of
notice of the Servicer’s failure to make such Advance) shall make an Advance of the premiums to maintain such insurance,
provided that, in each such case, such obligations shall be subject to the provisions of this Agreement concerning Nonrecoverable
Advances, the Trustee as mortgagee having an insurable interest and the availability of such insurance at commercially reasonable
rates.

 

(c)          
The Servicer or the Special Servicer, as applicable, may satisfy its obligations to cause insurance policies to be maintained
by maintaining a master force placed or blanket insurance policy insuring against losses on the Property or the Foreclosed Property,
as the case may be for which coverage is otherwise required to be maintained as set forth in the preceding subsections of this
Section 3.11. The incremental cost of such insurance allocable to the Property or Foreclosed Property, if not borne
by the Borrower, shall be paid by the Servicer as a Property Protection Advance unless it would be a Nonrecoverable Advance. If
such master force placed or blanket insurance policy contains a deductible clause, the Servicer or Special Servicer, as applicable,
shall deposit in the Collection Account out of its own funds all sums that would have been deposited in the Collection Account
but for such clause to the extent any such

 

    -100-

     

    

 

deductible
exceeds the deductible limitation that pertains to the Whole Loan, or in the absence of any such deductible limitation, the deductible
limitation that is consistent with Accepted Servicing Practices.

 

(d)          
Each of the 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 (rated by an insurance
company that has claims paying ability ratings of no lower than “A-” by S&P or, if not so rated, as otherwise acceptable
to S&P and Morningstar as confirmed in a Rating Agency Confirmation), covering its directors, officers, employees, as applicable,
in connection with its activities under this Agreement. Each such insurance policy shall protect the Servicer or the Special Servicer,
as applicable, against losses resulting directly from forgery, theft, embezzlement, fraud, errors and omissions of such covered
persons. Coverage of the Servicer or the Special Servicer under a policy or bond obtained by an Affiliate thereof and providing
the coverage required by this Section 3.11(d) shall satisfy the requirements of this Section 3.11(d). The amount
of coverage shall be at least equal to the coverage that is required by applicable governmental authorities having regulatory power
over the Servicer and the Special Servicer. If no such coverage amounts are imposed by such regulatory authorities, the amount
of coverage shall be at least equal to the coverage that would be required by FNMA or FHLMC with respect to the Servicer and the
Special Servicer if each were servicing and administering the Whole Loan for FNMA or FHLMC or as otherwise approved by FNMA or
FHLMC. In the event that any such bond or policy ceases to be in effect, the Servicer or the Special Servicer, as applicable, shall
obtain a comparable replacement bond or policy. Each shall use reasonable efforts to cause each and every sub-servicer, if any,
to maintain a blanket fidelity bond and an errors and omissions insurance policy meeting the requirements as described above. In
lieu of the foregoing, but subject to this Section 3.11, the Servicer and the Special Servicer shall be entitled to self-insure
with respect to such risks so long as it (or its immediate or ultimate parent) is rated at least “A-” or its equivalent
by S&P (or, if not so rated, as otherwise acceptable to S&P and Morningstar as confirmed in a Rating Agency Confirmation).

 

(e)          
No provision of this Section 3.11 requiring such fidelity bond and errors and omissions insurance shall diminish
or relieve the Servicer or the Special Servicer from its duties and obligations as set forth in this Agreement. The Certificate
Administrator shall be entitled to request, upon receipt of a written request from any Certificateholder, and the Servicer and
the Special Servicer shall each deliver or cause to be delivered to the Certificate Administrator, a certificate of insurance from
the surety and insurer certifying that such insurance is in full force and effect. The Certificate Administrator will make any
such certificate of insurance available to the requesting Certificateholder.

 

3.12.        Procedures with Respect to Defaulted Loan; Realization upon the Property. (a)  Upon a Loan Event of Default,
the Special Servicer on behalf of the Trust and the Companion Loan Holders (subject to the rights of the Risk Retention Consultation
Party and Directing Holder during any Subordinate Control Period (and upon non-binding consultation with the Directing Holder and
Risk Retention Consultation Party (unless it is a Borrower Related Party) during any Subordinate Consultation Period)), subject
to the terms of the Loan Documents and the Co-Lender Agreement and consistent with Accepted Servicing Practices, shall promptly
pursue the remedies set forth therein or otherwise available in accordance with Accepted

 

    -101-

     

    

 

Servicing
Practices, including foreclosure or otherwise realization on the Property and the other collateral for the Whole Loan. In connection
with any foreclosure, enforcement of the Loan Documents or other realization on the Collateral, the Special Servicer shall direct
the Servicer to, and the Servicer shall, pay the costs and expenses in any such proceedings as a Property Protection Advance unless
the Servicer determines, in accordance with Accepted Servicing Practices, that such Advance would constitute a Nonrecoverable
Advance, in which case it will be an expense of the Trust.

 

(b)          
Such proposed acceleration of the Whole Loan and/or foreclosure on the Property shall be taken unless the Special Servicer
waives such Loan Event of Default (or modifies or amends the Whole Loan to cure the Loan Event of Default), which the Special Servicer
may do if such modification, waiver or amendment is consistent with Accepted Servicing Practices and does not cause either the
Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify as a REMIC under the REMIC Provisions or constitute a “significant
modification” of the Whole Loan under Treasury Regulations Section 1.860G-2(b).

 

(c)          
In connection with such foreclosure as described in Section 3.12(a) or other realization on the Property, the
Special Servicer shall follow Accepted Servicing Practices; provided, however, that the Special Servicer shall not
be permitted to direct the Servicer, and neither the Special Servicer nor the Servicer shall be required, to expend its own funds
to restore damage done to the Property by an Uninsured Cause unless the Servicer or the Special Servicer, as applicable, permitted
the related insurance policy to lapse in violation of its respective obligations hereunder. If the Servicer does expend its own
funds to restore the Property damaged by an Uninsured Cause (which insurance policy did not lapse in violation of the Servicer’s
obligations), such expense shall be a Property Protection Advance. In connection with any foreclosure, enforcement of the Loan
Documents or other realization on the Collateral, the Special Servicer shall direct the Servicer to, and the Servicer shall, pay
the costs and expenses in any such proceedings as a Property Protection Advance unless the Servicer determines, in accordance with
Accepted Servicing Practices, that such Advance would constitute a Nonrecoverable Advance.

 

(d)          
Notwithstanding the foregoing, the Special Servicer may not foreclose on the Property on behalf of the Trust Fund and the
Companion Loan Holders and thereby be the beneficial owner of the Property, or take any other action with respect to such item
that would cause the Trustee, on behalf of the Certificateholders or Companion Loan Holders, to be considered to hold title to,
to be a “mortgagee-in-possession” of, or to be an “owner” or “operator” of the Property within
the meaning of CERCLA or any comparable law, unless the Special Servicer has previously determined, based on a report prepared
at the expense of the Trust Fund by an independent person who regularly conducts site assessments for purchasers of comparable
properties (a copy of such report to be provided to the Trustee and the Companion Loan Holders by the Special Servicer), that (i) the
Property is in compliance with applicable environmental laws or that taking the remedial actions necessary to comply with such
laws is reasonably likely to produce a greater recovery on a present value basis than not taking such actions and (ii) there
are no circumstances known to the Special Servicer relating to the use of hazardous substances or petroleum-based materials which
require investigation or remediation, or that if such circumstances exist taking such remedial actions is reasonably likely to
produce a greater recovery on a net present value basis than not taking such actions. The Special Servicer

 

    -102-

     

    

 

shall
deliver a copy of any such report to the 17g-5 Information Provider in electronic format (and the 17g-5 Information Provider shall
make such report available on its website to the Rating Agencies and NRSROs pursuant to Section 8.14(b)).

 

If the Special Servicer has so
determined based on satisfaction of the criteria in this Section 3.12(d) that it would be in the best economic interest
of the Trust Fund and the Companion Loan Holders (as a collective whole as if the Trust Fund and the Companion Loan Holders constituted
a single lender) (as determined in accordance with Accepted Servicing Practices) to institute a foreclosure or take any other actions
described in the immediately preceding paragraph, subject to the rights of the Directing Holder to consent to and/or consult and
the right of the Risk Retention Consultation Party to consult in respect of such action, as applicable, pursuant to the terms hereof
and subject to the rights of the Mezzanine Lender, the Special Servicer shall take such proposed action. The Special Servicer shall
not foreclose upon or otherwise cause the Trust to acquire ownership of any Collateral other than the Property unless it receives
an Opinion of Counsel (the cost of which shall be paid by the Servicer as a Property Protection Advance unless the Servicer determines
that such Property Protection Advance would constitute a Nonrecoverable Advance, in which case it shall be an expense of the Trust)
to the effect that such acquisition will not cause the imposition of a tax on the Upper-Tier REMIC or the Lower-Tier REMIC (other
than a tax on “net income from foreclosure property” under Code Section 860G(c)) under the REMIC Provisions or cause
the Lower-Tier REMIC or Upper-Tier REMIC to fail to qualify as a REMIC at any time that the Certificates are outstanding.

 

If the Special Servicer commences
foreclosure of the Whole Loan, it shall promptly provide written notification of such action to the holder of the Mezzanine Loan
(or, if such Mezzanine Loan is part of a securitization trust, to the special servicer, the trustee, the certificate administrator
and the directing certificateholder of such securitization).

 

The Special Servicer shall direct
the Servicer to, and the Servicer shall, advance the cost of any such compliance, containment, clean up or remediation as a Property
Protection Advance unless the Servicer determines, in accordance with Accepted Servicing Practices, that such Advance would constitute
a Nonrecoverable Advance.

 

(e)           
The environmental site assessments contemplated by Section 3.12(d) shall be prepared by any Independent Person
who regularly conducts environmental site assessments for purchasers of comparable properties, as determined by the Servicer in
a manner consistent with Accepted Servicing Practices. The cost of each such environmental site assessment shall qualify as a Property
Protection Advance and shall be advanced by the Servicer unless the Servicer determines that such Advance would constitute a Nonrecoverable
Advance.

 

(f)           
Notwithstanding any provision herein to the contrary, the Special Servicer shall not hold for the benefit of the Certificateholders
and the Companion Loan Holders any personal property pursuant to this Section 3.12 unless:

 

(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

 

    -103-

     

    

 

(ii)          
the Special Servicer shall have obtained an Opinion of Counsel (the cost of which shall be paid by the Servicer as a Property
Protection Advance unless the Servicer determines that such Property Protection Advance would constitute a Nonrecoverable Advance
in which case the cost of such Opinion of Counsel shall be treated as a reimbursable expense of the Servicer related to foreclosure)
to the effect that the holding of such personal property by the Trust Fund will not cause the imposition of a tax on the Upper-Tier
REMIC or the Lower-Tier REMIC under the REMIC Provisions or cause the Upper-Tier REMIC or the Lower-Tier REMIC to fail to qualify
as a REMIC at any time that any Uncertificated Lower-Tier Interest or Certificate is outstanding.

 

(g)          
Notwithstanding any acquisition of title to the Property following a Loan Event of Default and cancellation of the Whole
Loan, the Whole Loan shall be deemed to remain outstanding and held by the Trust Fund (in the case of the Trust Loan) and by the
Companion Loan Holders (in the case of the Companion Loan) for purposes of the application of collections and shall be reduced
only by collections net of expenses. For purposes of all calculations hereunder, so long as the Whole Loan shall be deemed to remain
outstanding in accordance with the preceding sentence, (i) it shall be assumed that the unpaid principal balance of the Trust
Loan and Companion Loan immediately after any discharge is equal to the unpaid principal balance of the Trust Loan and Companion
Loan, as applicable, immediately prior to such discharge and (ii) Foreclosure Proceeds shall be applied as provided in Section 1.3(a).

 

3.13.        Custodian to Cooperate; Release of Items in the Mortgage File. From time to time and as appropriate for the servicing
of the Whole Loan or foreclosure of or realization on the Property, the Custodian shall, upon request of the Servicer or the Special
Servicer and delivery to the Custodian of a request for release in the form of Exhibit B hereto, release or cause to
be released any items from the Mortgage File to the Servicer or the Special Servicer, as the case may be, within the lesser of
(i) seven calendar days and (ii) five Business Days of its receipt of the related request for release and shall execute such documents
furnished to it as shall be necessary to the prosecution of any such proceedings. Such request for release shall obligate the Servicer
or the Special Servicer to return such items to the Custodian when the need therefor by the Servicer or the Special Servicer no
longer exists.

 

3.14.        Title and Management of Foreclosed Property. (a)  In the event that title to the Property is acquired for
the benefit of the Certificateholders and the Companion Loan Holders in foreclosure or by deed in lieu of foreclosure or otherwise,
the deed, certificate of sale or other comparable document shall be taken in the name of the Trustee, as trustee for the Holders
of the Natixis Commercial Mortgage Securities Trust 2017-75B, Commercial Mortgage Pass-Through Certificates, Series 2017-75B or
its nominee (which shall not include the Special Servicer), on behalf of the Trust Fund and the Companion Loan Holders or as otherwise
contemplated pursuant to Section 8.10. Title may be taken in the name of a limited liability company wholly owned by
the Trust and which is managed by the Special Servicer (the costs of which shall be advanced by the Servicer; provided that
such Advance would not be a Nonrecoverable Advance). Promptly after such acquisition of title, the Special Servicer shall consult
with counsel to determine when an Acquisition Date shall be deemed to occur under the REMIC Provisions with respect to the Property,
the expense of such consultation being treated as a Property Protection Advance, unless the Servicer determines that such Property
Protection Advance would constitute a Nonrecoverable Advance in which case it shall be treated as a

 

    -104-

     

    

 

reimbursable
expense of the Servicer related to the foreclosure. The Special Servicer, on behalf of the Trust Fund and the Companion Loan Holders,
shall dispose of any Foreclosed Property held by the Trust Fund as expeditiously as appropriate in accordance with Accepted Servicing
Practices, but in any event within the time period, and subject to the conditions, set forth in Sections 3.15 and
12.2. Subject to Sections 12.2 and 3.14(d), the Special Servicer may hire on behalf of the Trust Fund
and the Companion Loan Holders a Successor Manager to manage, conserve, protect and operate such Foreclosed Property for the Certificateholders
and Companion Loan Holders solely for the purpose of its prompt disposition and sale. In connection with such management and subject
to Section 3.4(c)(viii), the Successor Manager shall be entitled to the REO Management Fee solely from the Foreclosed
Property Account or the Collection Account pursuant to Section 3.4(c)(viii).

 

(b)          
The Special Servicer shall segregate and hold all funds collected and received in connection with the operation of any Foreclosed
Property separate and apart from its own funds and general assets and shall establish and maintain with respect to a Foreclosed
Property a Foreclosed Property Account in the name of the Special Servicer on behalf of the Trustee and the Companion Loan Holders
pursuant to Section 3.6.

 

(c)          
The Special Servicer shall have full power and authority, subject to Accepted Servicing Practices and the specific requirements
and prohibitions of this Agreement, to do any and all things in connection with a Foreclosed Property for the benefit of the Trust
Fund and the Companion Loan Holders (as a collective whole as if the Trust Fund and the Companion Loan Holders constituted a single
lender) on such terms as are appropriate and necessary for the efficient liquidation of such Foreclosed Property, so long as the
Special Servicer deems such actions to be consistent with Accepted Servicing Practices. Without limiting the generality of the
foregoing, the Special Servicer may retain an independent contractor to operate and manage the Foreclosed Property; provided,
however, the retention of an independent contractor will not relieve the Special Servicer of its obligations hereunder with
respect to the Foreclosed Property.

 

The Special Servicer shall deposit
or cause to be deposited on a daily basis in the Foreclosed Property Account all revenues received with respect to the Foreclosed
Property, and the Special Servicer shall cause to be withdrawn therefrom funds necessary for the proper operation, management and
maintenance of such Foreclosed Property and for other expenses related to the preservation and protection of such Foreclosed Property,
including, but not limited to:

 

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

 

(ii)          
all taxes, assessments, charges or other similar items in respect of such Foreclosed Property that could result or have
resulted in the imposition of a lien thereon; and

 

(iii)         
all costs and expenses necessary to preserve such Foreclosed Property, including the payment of ground rent, if any.

 

    -105-

     

    

 

To the extent that amounts on
deposit in the Foreclosed Property Account are insufficient for the purposes set forth in clauses (i) through (iii) above
(and all similar amounts or expenses), the Special Servicer shall direct the Servicer to, and the Servicer shall, make a Property
Protection Advance unless the Servicer determines, in accordance with Accepted Servicing Practices, that such Advance would constitute
a Nonrecoverable Advance.

 

(d)           
The Special Servicer, in the name of the Trust Fund and the Companion Loan Holders, may (subject to Section 3.14(a))
contract with any Successor Manager for the operation and management of any Foreclosed Property; provided that no such contract
shall impose individual liability on the Trustee or the Trust; provided, further, that:

 

(i)            
the terms and conditions of any such contract shall not be inconsistent herewith;

 

(ii)          
any such contract shall require, or shall be administered to require, that the Successor Manager (A) request that the Special
Servicer pay from the Foreclosed Property Account all costs and expenses incurred in connection with the operation and management
of any Foreclosed Property, and (B) remit all related revenues (net of such costs and expenses) to the Special Servicer, for deposit
into the Foreclosed Property Account, as soon as practicable but in no event later than the Business Day immediately following
receipt; and

 

(iii)          
none of the provisions of this Section 3.14 relating to any such contract or to actions taken through any such Successor
Manager shall be deemed to relieve the Special Servicer of any of its ordinary and regularly recurring duties and obligations to
the Trust Fund on behalf of the Certificateholders and the Companion Loan Holders with respect to the operation and management
of any Foreclosed Property.

 

The Special Servicer shall be
entitled, and to the extent required by the REMIC Provisions, shall be required, to enter into an 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. All Foreclosed
Property Management Fees shall be an expense of the Trust Fund and allocated in accordance with the allocation provisions of the
Co-Lender Agreement payable from the Foreclosed Property Account or subject to reimbursement pursuant to Section 3.4(c)(viii).
The Special Servicer agrees to monitor the performance of the Successor Manager and to enforce the obligations of the Successor
Manager on behalf of the Trust Fund and the Companion Loan Holders. Expenses incurred by the Special Servicer in connection herewith
shall qualify as Property Protection Advances.

 

(e)           
On or before the Determination Date, the Special Servicer shall withdraw from the Foreclosed Property Account and deposit
into the Collection Account the proceeds and collections received or collected since the preceding Remittance Date through the
Business Day prior to the Remittance Date on or with respect to any Foreclosed Property (including any funds no longer needed in
any reserves established as provided below), net of expenses paid therefrom and amounts reasonably expected to be needed to fund
any reserves deemed necessary for the operation, preservation and protection of such Foreclosed Property, including without limitation,

 

    -106-

     

    

 

the
creation of reasonable reserves for working capital, repairs, replacements and necessary capital improvements and other related
expenses.

 

3.15.        Sale of Foreclosed Property. (a)  In the event that title to the Property is acquired by the Special Servicer
for the benefit of the Certificateholders and the Companion Loan Holders in foreclosure or by deed in lieu of foreclosure or otherwise,
the deed, certificate of sale or other comparable document shall be taken in the name of the Trustee, or its nominee (which shall
not include the Special Servicer), on behalf of the Trust Fund and the Companion Loan Holders or as otherwise contemplated pursuant
to Section 8.10. The Special Servicer, on behalf of the Trust Fund and the Companion Loan Holders, shall sell any Foreclosed
Property as expeditiously as appropriate in accordance with Accepted Servicing Practices and the REMIC Provisions in a manner designed
to preserve the capital of the Certificateholders and not with a view to the maximization of profit, but in no event later than
the Rated Final Distribution Date in a manner provided under this Section 3.15.

 

(b)          
If the Special Servicer acquires any Foreclosed Property in the name of and on behalf of the Trust Fund and the Companion
Loan Holders, the Special Servicer shall be empowered, subject to the Code and to the specific requirements and prohibitions of
this Agreement, to do any and all things in connection with the management and operation thereof in accordance with Accepted Servicing
Practices, all on terms and for such period as the Special Servicer deems to be in the best interest of the Certificateholders
and the Companion Loan Holders, as a collective whole (as if such Certificateholders and the Companion Loan Holders constituted
one lender) and consistent with the REMIC Provisions.

 

(c)          
Subject to the consent and non-binding consultation rights of the Directing Holder and the non-binding consultation rights
of the Risk Retention Consultation Party to the extent set forth in this Agreement, the Special Servicer shall accept the highest
cash bid for any Foreclosed Property received from any person. However, in no event may such bid be less than an amount at least
equal to the Repurchase Price related to such Foreclosed Property through the date of sale and all reasonably estimated liquidation
expenses. In the absence of any such bid, the Special Servicer shall accept the highest cash bid which it determines is a fair
price based on Appraisals obtained within the last 9 months. If the highest bidder is the Borrower, an affiliate of the Borrower,
the Servicer, the Special Servicer, any Certificateholder (or any of their respective Affiliates), the Trustee shall determine
the fairness of the highest bid based upon an independent Appraisal; provided that if the Trustee is required to determine
whether a cash offer by an Interested Person constitutes a fair price, the Trustee may designate an independent third party expert
in real estate or commercial mortgage loan matters with at least five (5) years’ experience in valuation of or investment
in loans similar to the Whole Loan, which such expert shall be selected with reasonable care by the Trustee for the sole purpose
of determining whether any such cash offer constitutes a fair price for the Whole Loan; provided, further, that if
the Trustee so designates any such third party to make such determination, the Trustee shall be entitled to rely conclusively upon
such third party’s determination and the reasonable costs of all Appraisals, inspection reports and broker opinions of value
incurred by the Trustee in making such determination shall be reimbursable to it first, by the Servicer as an Advance, subject
to the Servicer’s determination that such amounts are not Nonrecoverable Advances, and then as an expense of the Trust Fund.
Notwithstanding the foregoing, but, during any Subordinate Control Period, subject to the consent rights of the Directing Holder
and the non-binding consultation

 

    -107-

     

    

 

rights
of the Risk Retention Consultation Party set forth in Section 9.3 herein, the Special Servicer shall not be obligated to
accept the higher cash offer if the Special Servicer determines, in accordance with Accepted Servicing Practices, that rejection
of such offer would be in the best interests of the Certificateholders and the Companion Loan Holders (as a collective whole,
as if such Certificateholders and the Companion Loan Holders constituted a single lender), and the Special Servicer may accept
a lower cash offer (from any person other than itself or an affiliate) if it determines, in accordance with Accepted Servicing
Practices, that acceptance of such offer would be in the best interests of the Certificateholders and the Companion Loan Holders
(as a collective whole, as if such Certificateholders and the Companion Loan Holders constituted a single lender). For avoidance
of doubt, the Directing Holder and the Risk Retention Consultation Party may submit bids on any Foreclosed Property in the same
manner and at the same time and place as any other bidder. Neither the Trustee, in its individual capacity, nor any of its Affiliates
may make an offer for or purchase any Foreclosed Property.

 

(d)          
Subject to the provisions of Sections 3.14 and 12.2, the Special Servicer shall act on behalf of the
Trust Fund and the Companion Loan Holders in negotiating and taking any other action necessary or appropriate in connection with
the sale of any Foreclosed Property, including the collection of all amounts payable in connection therewith. Any sale of any Foreclosed
Property shall be without recourse to the Trustee, the Depositor, the Certificate Administrator, the Servicer, the Special Servicer,
the Trust Fund, the Companion Loan Holders or the Certificateholders (except that any contract of sale and assignment and conveyance
documents may contain customary warranties, so long as the only recourse for breach thereof is to the Trust Fund) and if consummated
in accordance with the terms of this Agreement, none of the Trustee, the Depositor, the Certificate Administrator, the Companion
Loan Holders, the Servicer or the Special Servicer shall have any liability to any Certificateholder with respect to the purchase
price thereof accepted by the Special Servicer or the Trustee.

 

(e)          
The proceeds of any sale effected pursuant to this Section 3.15, after deduction of the expenses incurred in
connection therewith, shall be deposited in the Collection Account in accordance with Section 3.4(a).

 

(f)           
Within 30 days of the sale of any Foreclosed Property, if not previously included in a CREFC® Report provided
by the Servicer or the Special Servicer, the Special Servicer shall provide to the Servicer, the Trustee, the Certificate Administrator
and the Companion Loan Holders a statement of accounting for such Foreclosed Property, including, without limitation, (i) the
date such Foreclosed Property was acquired in foreclosure or by deed in lieu of foreclosure or otherwise, (ii) the date of
disposition of such Foreclosed Property, (iii) the gross sale price and related selling and other expenses, (iv) accrued
interest with respect to the Loan Principal Balance of such Foreclosed Property, calculated from the date of acquisition to the
disposition date, and (v) such other information as the Trustee, the Certificate Administrator or the Companion Loan Holders
may reasonably request.

 

(g)          
The Special Servicer shall prepare and file on a timely basis the reports of foreclosures and abandonments of the Property
required by Section 6050J of the Code and the reports of discharges of indebtedness income in respect of the Whole Loan required
by Section 6050P of the Code.

 

    -108-

     

    

 

3.16.         Sale of Defaulted Loan.

 

(a)           
(i) Within sixty (60) days after the occurrence of a Special Servicing Loan Event with respect to the Trust Loan, the Special
Servicer shall order (but shall not be required to have received) an Appraisal for the Property. The Special Servicer shall promptly
notify in writing the Servicer, the Trustee, the Certificate Administrator, the Companion Loan Holders, the Risk Retention Consultation
Party and the Directing Holder (during any Subordinate Control Period or Subordinate Consultation Period) of the occurrence of
such Special Servicing Loan Event. Upon delivery by the Special Servicer of the notice described in the preceding sentence, and
subject to the rights of the Mezzanine Lender to purchase the Whole Loan pursuant to the Intercreditor Agreement, the right of
the Junior Companion Loan Holder (if a Control Appraisal Period is not continuing) to consent to a Major Decision and the Directing
Holder under Section 9.3, the Special Servicer may offer to sell to any Person the Whole Loan or may offer to purchase the
Whole Loan, if and when the Special Servicer determines, consistent with Accepted Servicing Practices, that no satisfactory arrangements
can be made for collection of delinquent payments thereon and such a sale would be in the best economic interests of the Trust
and the Companion Loan Holders (as a collective whole as if such Certificateholders and Companion Loan Holders constituted a single
lender) on a net present value basis. The Special Servicer shall provide the Trustee, the Certificate Administrator, the Companion
Loan Holders, the Risk Retention Consultation Party (unless it is a Borrower Related Party) and the Directing Holder (during any
Subordinate Control Period or Subordinate Consultation Period) not less than five (5) Business Days’ (and with regard to
the Junior Companion Loan Holder, 15 Business Days) prior written notice of its intention to sell the Whole Loan, in which case
the Special Servicer is required to accept the highest cash offer received from any Person (other than any Interested Person) for
the Whole Loan in an amount at least equal to the related Repurchase Price or, at its option, if it has received no offer at least
equal to the related Repurchase Price therefor, purchase the Whole Loan at the related Repurchase Price. Any Appraisal obtained
pursuant to this Section 3.16 will be delivered by the Special Servicer to the Certificate Administrator in electronic
format and the Certificate Administrator shall make such Appraisal available to Privileged Persons pursuant to Section 8.14(b).
The Companion Loan shall be sold together with the Whole Loan, subject to this Section 3.16 and any additional requirements
set forth in the Co-Lender Agreement.

 

(ii)           
In the absence of any offer at least equal to the related Repurchase Price (or purchase by the Special Servicer for such
price), the Special Servicer shall accept the highest cash offer received from any Person that is determined by the Special Servicer
to be a fair price for the Defaulted Loan, if the highest cash offeror is the Depositor, the Servicer, the Special Servicer, a
Holder of 50% or more of the Controlling Class, the Directing Holder, the Risk Retention Consultation Party, the Certificate Administrator,
the Borrower, any property manager, any independent contractor engaged by the Special Servicer, a holder of any interest in a Mezzanine
Loan, any Companion Loan Holder or any known affiliate of any of the foregoing (any such person, an “Interested Person”),
then the Trustee (based upon, among other things, the Appraisal ordered pursuant to the preceding paragraph (the cost of which
shall be paid by the Servicer as a Property Protection Advance) and copied or otherwise delivered to the Trustee) shall determine
if the highest cash offer is a fair price and such determination shall be binding upon all parties; provided that if the
Trustee is required to determine whether a cash offer by an

 

    -109-

     

    

 

Interested
Person constitutes a fair price, the Trustee may designate an independent third party expert in real estate or commercial mortgage
loan matters with at least five (5) years’ experience in valuation of or investment in loans similar to the Defaulted Loan,
which such expert shall be selected with reasonable care by the Trustee for the sole purpose of determining whether any such cash
offer constitutes a fair price for the Defaulted Loan; provided, further, that if the Trustee so designates any
such third party to make such determination, the Trustee shall be entitled to rely conclusively upon such third party’s
determination and the reasonable costs of all appraisals, inspection reports and broker opinions of value incurred by the Trustee
in making such determination shall be reimbursable to it first, by the Servicer as an Advance, subject to the Servicer’s
determination that such amounts are not Nonrecoverable Advances, and then as an expense of the Trust. Neither the Trustee, in
its individual capacity, nor any of its Affiliates may make an offer for or purchase the Defaulted Loan. For avoidance of doubt,
the Directing Holder and the Risk Retention Consultation Party may submit bids on the defaulted Loan in the same manner and at
the same time and place as any other bidder.

 

(iii)         
The Special Servicer shall not be obligated to accept the highest cash offer if the Special Servicer determines, in accordance
with Accepted Servicing Practices, that the rejection of such offer would be in the best interests of the Certificateholders and
the Companion Loan Holders (as a collective whole, giving due regard to the relative subordination of the Trust A-B Note and the
Non-Trust B Note). In addition, the Special Servicer may accept a lower cash offer if it determines, in accordance with Accepted
Servicing Practices, that the acceptance of such offer would be in the best interests of the Certificateholders and the Companion
Loan Holders (as a collective whole as if such Certificateholders and the Companion Loan Holders constituted as single lender);
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 efforts consistent with Accepted Servicing Practices to sell the Defaulted Loan prior to the Rated Final Distribution
Date.

 

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

 

(b)          
Any sale of the Defaulted Loan by the Special Servicer shall be subject to the Directing Holder’s consent and non-binding
consultation rights and the Risk Retention Consultation Party’s non-binding consultation rights as described in Section
9.3 herein.

 

(c)          
The right of the Special Servicer to purchase or sell the Defaulted Loan after the occurrence of a Special Servicing Loan
Event shall terminate, and shall not be exercisable as set forth in clause (a) above (or if exercised but the purchase
of the Defaulted Loan has not yet occurred, the Special Servicer’s right shall terminate and such exercise shall be of no
further force or effect) if the Defaulted Loan is no longer delinquent as a result of any of the following: (i) the Special Servicing
Loan Event has ceased pursuant to the terms of this Agreement, (ii) the Defaulted Loan has become subject to a fully executed agreement
reflecting

 

    -110-

     

    

 

the
terms of a workout arrangement, (iii) the Defaulted Loan has otherwise been resolved (including by a full or discounted pay-off)
or (iv) the Mezzanine Lender has purchased the Trust Loan pursuant to its purchase option for the Trust Loan under the intercreditor
agreement.

 

(d)          
Any sale of the Defaulted Loan pursuant to Section 3.16(a) shall be for cash only.

 

(e)          
The Special Servicer shall have the obligation to sell the Defaulted Loan (including the Companion Loan) pursuant to the
terms of the Co-Lender Agreement as if the Trust Loan and the Companion Loans were one whole loan on behalf of the Certificateholders
and the Companion Loan Holders. The Special Servicer shall provide notice to the Companion Loan Holders or, if applicable, the
applicable Other Special Servicer (if any) as soon as practicable following its decision to attempt to sell, and prior to the commencement
of marketing of, the Companion Loan.

 

3.17.         Servicing Compensation. (a)  The Servicer shall be entitled to receive the Servicing Fee with respect to
the Whole Loan and Foreclosed Property payable monthly out of the Collection Account from payments of interest on the Whole Loan
or Foreclosure Proceeds allocable as interest on such Foreclosed Property, as the case may be in accordance with and subject to
Section 3.4(c)(ii). The Servicer shall be entitled to retain as compensation any late payment charges and certain other
customary charges and fees to the extent described below, as well as reimbursement for all other costs or expenses incurred by
it in performing its duties hereunder other than: (i) fees of any sub-servicer and the expenses of any sub-servicer that would
not be reimbursable to Servicer if such expenses were incurred by the Servicer; (ii) the cost of any fidelity bond or errors
and omissions policy required by Section 3.11(d); (iii) overhead expenses of the Servicer including but not limited
to those which may properly be allocable under the Servicer’s accounting system or otherwise to the Servicer’s activities
under this Agreement or the income derived by it hereunder including the costs to the Servicer associated with employees of the
Servicer performing services in connection with the obligations of the Servicer hereunder; and (iv) costs and expenses arising
from the negligence, bad faith or willful misconduct of the Servicer in connection with its servicing obligations hereunder (the
“Servicer Customary Expenses”). So long as no Special Servicing Loan Event has occurred and is continuing, the
Servicer shall also be entitled to retain certain other customary charges and fees including any late payment charges (including
any late payment fees collected after the occurrence of a Special Servicing Loan Event but accrued prior to such Special Servicing
Loan Event) (to the extent not applied pursuant to Section 3.4(c)), assumption fees (except as otherwise provided in
the Co-Lender Agreement)), Default Interest (to the extent not applied pursuant to Section 3.4(c) (except as otherwise provided
in the Co-Lender Agreement)), assumption application fees, substitution fees, defeasance fees, Modification Fees, consent fees
(subject to the fourth paragraph of this Section 3.17), loan service transaction fees, insufficient funds fees and similar
fees and expenses to the extent, with respect to any such amounts, collected and allocated to such amounts as permitted by (or
not otherwise prohibited by) the terms of the Loan Documents and the Co-Lender Agreement and this Agreement (in each case, to the
extent actually received from the Borrower), release fees and any income earned (net of losses to the extent provided in this Agreement)
on the investment of funds deposited in the Collection Account, the Senior Companion Loan Account and any Reserve Accounts (to
the extent not payable to the Borrower) to the extent provided for in this Agreement (“Additional

 

    -111-

     

    

 

Servicing Compensation”); provided, however, that the Servicer shall not be entitled
to apply or retain any Default Interest or any late payment charges, with respect to the Whole Loan, with respect to which a default
thereunder or Loan Event of Default is continuing unless and until such default or Loan Event of Default has been cured and all
delinquent amounts due with respect to the Whole Loan have been paid.

 

If a Special Servicing Loan Event
occurs and is continuing with respect to the Whole Loan, the Special Servicer shall be entitled to receive a Special Servicing
Fee with respect to the Whole Loan for so long as such Special Servicing Loan Event continues as well as reimbursement for all
other costs or expenses incurred by it in performing its duties hereunder other than: (i) the cost of any fidelity bond or
errors and omissions policy required by Section 3.11(d); (ii) overhead expenses of the Special Servicer including
but not limited to those which may properly be allocable under the Special Servicer’s accounting system or otherwise to the
Special Servicer’s activities under this Agreement or the income derived by it hereunder including the costs to the Special
Servicer associated with employees of the Special Servicer performing services in connection with the obligations of the Special
Servicer hereunder; and (iii) costs and expenses arising from the negligence, bad faith or willful misconduct of the Special
Servicer in connection with its servicing obligations hereunder (the “Special Servicer Customary Expenses”).
If a Special Servicing Loan Event is terminated following resolution of such Special Servicing Loan Event by a written agreement
with the Borrower negotiated by the Special Servicer, the Special Servicer shall be entitled to receive the Work-out Fee on all
payments of principal and interest made on the Whole Loan following such written agreement for so long as another Special Servicing
Loan Event does not occur with respect to the Whole Loan. If the Special Servicer is terminated (other than for cause) or resigns
after such written agreement is entered into and before or after the Special Servicing Loan Event is terminated, it shall retain
the right to receive any and all Work-out Fees on all payments of principal and interest (other than at the Default Rate) made
on the Whole Loan following such written agreement (negotiated by such Special Servicer prior to its termination or resignation)
for so long as another Special Servicing Loan Event does not occur with respect to the Whole Loan and the successor Special Servicer
shall have no rights with respect to such Work-out Fee. In addition, the Special Servicer shall be entitled to receive a Liquidation
Fee with respect to each Liquidated Property or the liquidation of the Whole Loan (whether through sale, discounted payoff or other
liquidation) as to which the Special Servicer receives Net Liquidation Proceeds, except that no Liquidation Fee shall be payable
in connection with (a) a repurchase of the Trust Loan by the Loan Seller pursuant to the Loan Purchase Agreement (so long as such
repurchase occurs within the 90 day time period required by the Loan Purchase Agreement including any applicable extended cure
periods), (b) the sale of the Whole Loan to the Servicer, the Special Servicer, the Directing Holder or any of their affiliates
pursuant to Section 3.16 hereof if such sale occurred within 90 days after the transfer of the Whole Loan to the Special
Servicer, (c) the purchase of the Whole Loan by the holder of the Mezzanine Loan within 90 days following the date that such holder’s
option was first given to such Mezzanine Lender or (d) the purchase of the Trust Loan by the Junior Companion Loan Holder within
90 days following the date such holder received notice of the first purchase option event triggering its right to purchase the
Trust Loan (it being acknowledged that if a later purchase option notice is issued as a result of another purchase option trigger
event arising out of substantially the same facts and circumstances, this clause (d) shall be inoperative). The Liquidation Fee
shall be payable from, and shall be calculated using, the related Net Liquidation Proceeds. Each of the foregoing fees shall be
payable from funds on

 

    -112-

     

    

 

deposit in the Collection Account as provided in Section 3.4(c). With respect to the Whole Loan
for which a Special Servicing Loan Event is continuing, the Special Servicer shall also be entitled to retain as additional servicing
compensation any late payment fees (to the extent not applied pursuant to Section 3.4(c)), (except as otherwise provided
in the Co-Lender Agreement) Default Interest (to the extent not applied pursuant to Section 3.4(c)), (except as otherwise
provided in the Co-Lender Agreement) assumption fees, assumption application fees, Modification Fees, loan service transaction
fees, consent fees (subject to the second paragraph below) and similar fees and expenses to the extent, with respect to any such
amounts, collected (to the extent permitted by (or not otherwise prohibited by) and allocated to such amounts in accordance with
the terms of the Loan Documents or the Co-Lender Agreement or this Agreement, and any income earned (net of losses to the extent
provided in this Agreement) on the investment of funds deposited in the Foreclosed Property Account to the extent provided in this
Agreement (“Additional Special Servicing Compensation”). Notwithstanding the foregoing, in the event that the
Whole Loan has become a Specially Serviced Loan solely due to the failure to make the Balloon Payment and the Whole Loan is refinanced
on or before the date that is four (4) months after the Maturity Date, the Special Servicer shall be entitled to collect a Liquidation
Fee or Work-out Fee only from the Borrower and shall not otherwise be entitled to deduct a Liquidation Fee from amounts due to
the Certificateholders or the Companion Loan Holders.

 

Notwithstanding anything herein
to the contrary, with respect to the Whole Loan and any Collection Period, the Special Servicer shall only be entitled to receive
a Work-out Fee or a Liquidation Fee with respect to the Whole Loan, but not both.

 

The Special Servicer shall also
be entitled, if the Whole Loan is a Specially Serviced Loan, to 100% of the consent fees or Modification Fees, and if the Whole
Loan is not a Specially Serviced Loan, 50% of the consent fees or Modification Fees that are paid in connection with a consent
or modification that the Servicer is not permitted to take in the absence of the consent or approval (or deemed consent or approval)
of the Special Servicer under this Agreement, in each case, to the extent that such consent fee or Modification Fee is actually
collected on the Whole Loan.

 

The 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
percentage interest in any fee or payment payable to such party; provided, however without the consent of the affected
party, (x) neither the Servicer nor the Special Servicer shall have the right to reduce or elect not to charge the percentage interest
of any fee due to the other and (y) to the extent either of the Servicer or the Special Servicer exercises its right to reduce
or elect not to charge its respective percentage interest in any fee, the party that reduced or elected not to charge such fee
shall not have any right to share in any portion of the other party’s fee. For the avoidance of doubt, if the Servicer decides
not to charge any fee, the Special Servicer shall still be entitled to charge the portion of the related fee the Special Servicer
would have been entitled to if the Servicer had charged a fee and the Servicer shall not be entitled to any of such fee charged
by the Special Servicer.

 

Notwithstanding any other provision
in this Agreement, neither the Servicer nor the Special Servicer, as applicable, shall be entitled to reimbursement for an expense
incurred under this Agreement or in connection with the performance of its duties hereunder unless (i) the

 

    -113-

     

    

 

amount of such
payment to the Servicer or the Special Servicer, as the case may be, is reimbursed to the Trust Fund by the Borrower (to the extent
the Borrower is required to do so under the Loan Agreement); (ii) failure of the Borrower to reimburse for such payment constitutes
a Loan Event of Default; (iii) such expense would qualify as an “unanticipated expense incurred by the REMIC”
within the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii) or is otherwise an unanticipated expense (it being understood
that the Servicer Customary Expenses and the Special Servicer Customary Expenses are not unanticipated); or (iv) such reimbursement
is expressly provided for herein or such expense is expressly described herein as an expense of the Trust Fund or as an Advance.

 

Except as otherwise expressly
provided herein, no transfer, sale, pledge or other disposition of the Servicer’s right to receive all or any portion of
the Servicing Fee (or the Special Servicer’s right to receive all or any portion of the Special Servicing Fee) or other servicing
compensation provided for herein shall be made, and any such attempted transfer, sale, pledge or other disposition shall be void,
unless such transfer is made to a successor Servicer or successor Special Servicer, as applicable, in connection with the assumption
by such successor of the duties hereunder pursuant to Section 7.2.

 

KeyBank National Association
and any successor holder of the Excess Servicing Fee Rights shall be entitled, at any time, at its own expense, to transfer, sell,
pledge or otherwise assign such Excess Servicing Fee Rights in whole (but not in part), to any QIB or Institutional Accredited
Investor (other than a Benefit Plan); provided that no such transfer, sale, pledge or other assignment shall be made unless
(i) that transfer, sale, pledge or other assignment is exempt from the registration and/or qualification requirements of the
Securities Act and any applicable state securities laws and is otherwise made in accordance with the Securities Act and such state
securities laws, (ii) the prospective transferor shall have delivered to the Depositor a certificate substantially in the
form attached as Exhibit M-6 hereto, and (iii) the prospective transferee shall have delivered to KeyBank National
Association and the Depositor a certificate substantially in the form attached as Exhibit M-7 hereto. None of the Depositor,
the Trustee or the Certificate Administrator is obligated to register or qualify an Excess Servicing Fee Right under the Securities
Act or any other securities law or to take any action not otherwise required under this Agreement to permit the transfer, sale,
pledge or assignment of an Excess Servicing Fee Right without registration or qualification. KeyBank National Association and each
holder of an Excess Servicing Fee Right desiring to effect a transfer, sale, pledge or other assignment of such Excess Servicing
Fee Right shall, and KeyBank National Association hereby agrees, and each such holder of an Excess Servicing Fee Right by its acceptance
of such Excess Servicing Fee Right shall be deemed to have agreed, in connection with any transfer of such Excess Servicing Fee
Right effected by such Person, to indemnify the Certificateholders, the Trust, the Depositor, the Initial Purchasers, the Trustee,
the Servicer and the Special Servicer against any liability that may result if such transfer is not exempt from registration and/or
qualification under the Securities Act or other applicable federal and state securities laws or is not made in accordance with
such federal and state laws or in accordance with the foregoing provisions of this paragraph. By its acceptance of an Excess Servicing
Fee Right, the holder thereof shall be deemed to have agreed not to use or disclose such information in any manner that could result
in a violation of any provision of the Securities Act or other applicable securities laws or that would require registration of
such Excess Servicing Fee Right or any Certificate pursuant to the Securities Act. Following any transfer, sale, pledge or assignment
of an Excess Servicing Fee

Right or the termination of KeyBank National Association as the Servicer, the Person then acting as
the Servicer, shall pay, out of each amount paid to such Servicer as Servicing Fees, the related Excess Servicing Fees to the holder
of such Excess Servicing Fee Right within one (1) Business Day following the payment of such Servicing Fees to such Servicer, in
each case in accordance with payment instructions provided by such holder in writing to such Servicer. The holder of an Excess
Servicing Fee Right shall not have any rights under this Agreement except as set forth in the preceding sentences of this paragraph.
None of the Depositor, the Special Servicer or the Trustee shall have any obligation whatsoever regarding payment of the Excess
Servicing Fee or the assignment or transfer of the Excess Servicing Fee Right.

 

As compensation for its activities
hereunder, on each Distribution Date the Certificate Administrator shall be entitled to the Certificate Administrator Fee and the
Trustee shall be entitled to the Trustee Fee. Except as otherwise provided herein (i) the Certificate Administrator’s fee
includes all overhead expenses of the Certificate Administrator and the Authenticating Agent and (ii) the Trustee Fee includes
all overhead expenses of the Trustee. Each of the Trustee’s and Certificate Administrator’s rights to the Certificate
Administrator Fee and the Trustee Fee, as applicable, may not be transferred in whole or in part except in connection with the
transfer of all of the Trustee’s or Certificate Administrator’s, as applicable, responsibilities and obligations under
this Agreement.

 

The Special Servicer and its
Affiliates shall be prohibited from receiving or retaining any compensation or any other remuneration (including, without limitation,
in the form of commissions, brokerage fees, rebates, or as a result of any other fee-sharing arrangement) from any Person (including,
without limitation, the Trust, the Borrower, the Sponsor, any property manager or indemnitor in respect of the Whole Loan and any
purchaser of the Whole Loan or Foreclosed Property) in connection with the disposition or workout of the Whole Loan, the management
or disposition of the Foreclosed Property, or the performance of any other special servicing duties under this Agreement, other
than as expressly provided in this Section 3.17 provided, however, that such prohibition shall not apply to Permitted
Special Servicer/Affiliate Fees.

basis within 30 days after the Servicer’s receipt of the Borrower’s quarterly financials (commencing within 30 days
of the receipt of the Borrower’s financials for the quarter ending June 30, 2017 and annually within 30 days after receipt
of the Borrower’s annual financials (commencing within 30 days of receipt of the Borrower’s annual financials for the
year ending December 31, 2017.

 

Notwithstanding anything herein
to the contrary, the Servicer shall deliver the CREFC® Operating Statement Analysis Report and the CREFC®
NOI Adjustment Worksheet to the Certificate Administrator on a monthly basis not later than 5:00 p.m. (New York time) on the Business

extent such analysis or update is not required to be provided under the then current applicable CREFC® guidelines.
With respect to the Companion Loan, the Servicer shall (no later than the time(s) that it or any portion thereof is made available
to the Certificate Administrator) make available to the Companion Loan Holders (if such Companion Loan Holder is not the Borrower
or an Affiliate thereof) or, if the Companion Loan is securitized, the respective Other Servicer, the CREFC® Investor
Reporting Package (excluding any templates) pursuant to the terms of this Agreement on a monthly basis. The Special Servicer shall
provide any templates relating to the Companion Loan included in the CREFC® Investor Reporting Package and prepared
by the Special Servicer pursuant to the terms hereof to the Servicer promptly upon reasonable request. The Servicer shall provide
any templates relating to the Companion Loan included in the CREFC® Investor Reporting Package (with respect to
templates required to be prepared by the Special Servicer pursuant to the terms hereof, to the extent received) to the Other Servicer
upon reasonable request.

 

(b)          The Servicer shall furnish to the Certificate Administrator and the 17g-5 Information Provider, which shall post them to
its website pursuant to Section 8.14(b), in electronic format the CREFC® Reports produced by it pursuant
to this Agreement not later than the time period specified in Section 3.18(a).

 

(c)          The Servicer shall produce the reports described in this Section 3.18 solely from information provided to the
Servicer by the Borrower pursuant to the Loan Agreement (without modification, interpretation or analysis) or by the Special Servicer,
Loan Seller or Depositor pursuant to this Agreement. None of the Trustee, the Certificate Administrator, any Companion Loan Holder,
the Servicer or the Special Servicer shall be responsible for the completeness or accuracy of such information (except that the
Servicer shall use efforts consistent with Accepted Servicing Practices to correct patent errors).

 

(d)          With respect to each Collection Period, the Special Servicer shall deliver or cause to be delivered to the Certificate Administrator,
without charge and within two Business Days following the related Determination Date, an electronic report that discloses and contains

3.20.          [Reserved]

 

3.21.          Access to Certain Documentation Regarding the Trust Loan and Other Information. (a)  Upon reasonable advance
notice, the Certificate Administrator shall provide reasonable access during its normal business hours at its Corporate Trust Office
to certain reports and to information and documentation in its possession regarding the Trust Loan to any Privileged Person (other
than the Rating Agencies). With respect to the Borrower and any Affiliate thereof, such information is limited to the Distribution
Date Statement, and shall require the delivery of an Investor Certification in the form of Exhibit J-2 hereto.

 

(b)          Upon request of the Depositor or the Rating Agencies, the 17g-5 Information Provider shall post on the 17g-5 Information
Provider’s Website any additional information requested by the Depositor or the Rating Agencies (including without limitation
pursuant to clause (a) above) to the extent such information is delivered to the 17g-5 Information Provider electronically in accordance
with Section 8.14(b). In no event shall the 17g-5 Information Provider disclose on the 17g-5 Information Provider’s
Website which Rating Agency requested such additional information.

 

(c)          If any of the parties to this Agreement receives a Form ABS Due Diligence-15E from any party in connection with any third-party
due diligence services such party may have provided with respect to the Trust Loan (“Due Diligence Service Provider”),
such receiving party shall promptly forward such Form ABS Due Diligence-15E to the 17g-5 Information Provider for posting on the
17g-5 Information Provider’s Website. The 17g-5 Information Provider shall post on the 17g-5 Information Provider’s
Website any Form ABS Due Diligence-15E it receives directly from a Due Diligence Service Provider or from another party to this
Agreement, promptly upon receipt thereof.

 

3.22.          Inspections. The Servicer shall inspect or cause to be inspected the Property not less frequently than once each
year commencing in 2018, so long as a Special Servicing Loan Event is not then continuing; provided, however that
the Servicer will not be required to inspect the Property if it has been inspected in the previous 12 months. The Special Servicer
shall inspect or cause to be inspected the Property as soon as practicable following the occurrence of a related Special Servicing
Loan Event and annually for so long as a Specially Serviced Loan Event is continuing. The Servicer or the Special Servicer, as
applicable, shall further inspect, or cause to be inspected, the Property whenever it receives information that the Property has
been materially damaged, left vacant, or abandoned, or if waste is being committed thereto. All such inspections shall be performed
in such manner as shall be consistent with Accepted Servicing Practices. The cost of the annual inspections referred to in the
first sentence of this paragraph shall be an expense of the Servicer; the cost of all additional inspections referred to in this
paragraph shall be a Trust Fund Expense and if paid by the Servicer shall constitute a Property Protection Advance or an Administrative
Advance. The Servicer or Special Servicer, as the case may be, shall prepare a written report of inspection and deliver it to the
Certificate Administrator, the 17g-5 Information Provider and the Companion Loan Holders in electronic format. The Certificate
Administrator shall post such report on the Certificate Administrator’s Website, pursuant to Section 8.14(b).

3.23.          
Advances. (a)  In the event that a Monthly Payment (other than any Balloon Payment or any Default Interest,
but including any Assumed Monthly Payment) or any portion of a Monthly Payment (or Assumed Monthly Payment, as applicable) representing
interest and/or principal, if any, on the Trust Loan has not been received by the Business Day immediately prior to the Remittance
Date, the Servicer, subject to its determination that such amounts are not Nonrecoverable Advances, shall make an advance on such
Remittance Date to the Distribution Account, in an amount equal to the Monthly Payment (or Assumed Monthly Payment, as applicable)
or any such portion of such Monthly Payment (or Assumed Monthly Payment, as applicable) on the Trust Loan that was delinquent as
of the close of the Business Day immediately prior to such Remittance Date (net of the Servicing Fee with respect to the Trust
Loan, which shall not be paid to the Servicer until funds in the Collection Account are available for payment of such fee); provided
that neither the Servicer nor any other party shall be entitled to interest accrued on the amount of any Monthly Payment Advance
with respect to the Trust Loan if the related Monthly Payment (or, if applicable, the Assumed Monthly Payment) in respect of the
Trust Loan is received by the Servicer or the Certificate Administrator, as applicable, by 2:00 p.m., New York time, on such
Remittance Date. (For the avoidance of doubt, neither the Trustee nor the Servicer will have any obligation to make any principal
and/or interest debt service advances with respect to any Companion Loan). The Servicer shall also advance in respect of each Loan
Payment Date following a delinquency in the payment of any Balloon Payment of the Trust Loan or a foreclosure (or acceptance of
a deed in lieu of foreclosure or comparable conversion) of the Whole Loan, not later than the related Remittance Date, to the Distribution
Account, the amount of any Assumed Monthly Payment deemed due with respect to the Trust Loan on such Loan Payment Date. For the
avoidance of doubt, in the event that the amount of interest and principal, if any, due on the Trust Loan is reduced as a result
of any modification to the Trust Loan, any future Monthly Payment Advance made with respect to the modified Trust Loan shall be
in such amounts as may be required as a result of such reduction. Notwithstanding anything to the contrary herein and subject to
the determination of non-recoverability provided in this Section 3.23, in the event that the Property becomes a Foreclosed
Property, the Servicer shall continue to make advances as required pursuant to this Section 3.23(a) with respect to
each Loan Payment Date following such event in an amount equal to the Monthly Payment or the Assumed Monthly Payment, as applicable,
due or deemed due with respect to the Trust Loan on such Loan Payment Date, as if the Property had not become a Foreclosed Property
and the Trust Loan continued to be outstanding. If and to the extent such information is not already included in the Distribution
Date Statement for the month in which such Monthly Payment Advance is made, the Servicer shall notify the master servicer and trustee
with respect to each Senior Companion Loan Securitization Trust of the amount of any Monthly Payment Advance made pursuant to this
Section 3.23(a) within two Business Days of making such advance. The Servicer shall maintain a record of each Monthly Payment
Advance it has made pursuant to this Section 3.23(a) on the Trust Loan and shall notify the Certificate Administrator
thereof in the appropriate CREFC® Reports in order to permit allocation thereof pursuant to Sections 3.4
and 3.5. In the event that the Servicer does not remit any amounts required to be remitted to the Certificate Administrator
on each Remittance Date (including any amounts required to be remitted pursuant to Section 3.5 and any required Monthly
Payment Advance) to the Certificate Administrator for deposit in the Distribution Account on the Remittance Date, the Servicer
shall pay to the Certificate Administrator interest on such amounts

 

    -118-

     

    

 

at the federal funds rate for the period from and including
the Remittance Date to but excluding the Distribution Date or, if earlier, the actual remittance date.

 

At any time that an Appraisal
Reduction Amount exists with respect to the Trust Loan, the amount that would otherwise be required to be advanced by the Servicer
in respect of delinquent payments of interest on the Trust Loan shall be reduced by multiplying such amount by a fraction, the
numerator of which is the then outstanding principal balance of the Trust Loan minus the Appraisal Reduction Amount allocated to
the Trust Loan and the denominator of which is the then outstanding principal balance of the Trust Loan.

 

Notwithstanding the foregoing,
at no time shall the Servicer or the Trustee be required to make a Monthly Payment Advance as described in this Section 3.23(a)
with respect to the Trust Loan if it has been repurchased from the Trust Fund by the Loan Seller as contemplated in Section
2.7(b).

 

(b)          Subject to Section 3.23(e), the Servicer shall advance, to the extent it determines that such amount is not
non-recoverable, all customary and reasonable out-of-pocket costs and expenses incurred by the Servicer or the Special Servicer
in the performance of its servicing obligations, including, but not limited, to the costs and expenses incurred in connection with
(i) the preservation, restoration, operation and protection of the Property which, in the Servicer’s sole discretion,
exercised in accordance with Accepted Servicing Practices, are necessary to prevent an immediate or material loss to the Trust
Fund’s interest in the Property, (ii) the payment of (A) real estate taxes, assessments and governmental charges
that may be levied or assessed against the Borrower or any of its Affiliates or the Property or revenues therefrom or which become
liens on the Property, (B) insurance premiums and (C) the out-of-pocket costs and expenses of the Servicer or the Special
Servicer, as applicable (including, without limitation, reasonable attorneys’ fees and expenses) to the extent not paid by
the Borrower that are incurred in connection with a sale of the Whole Loan, the negotiation of a workout of the Whole Loan, an
assumption of the Whole Loan or a release of the Property from the lien of the Mortgage, (iii) any enforcement or judicial
proceedings, including foreclosures and including, but not limited to, court costs, attorneys’ fees and expenses and costs
for third party experts, including Independent Appraisers, environmental and engineering consultants, and (iv) the management,
operation and liquidation of the Property if the Property is acquired by the Special Servicer or its Affiliate in the name of the
Trustee for the benefit of the Certificateholders and the Companion Loan Holders (collectively, “Property Protection Advances”).
In addition, subject to Section 3.23(e), the Servicer shall advance Borrower Reimbursable Trust Fund Expenses to the
extent not otherwise covered by any Property Protection Advance (collectively, “Administrative Advances”). (For
the avoidance of doubt, neither the Servicer nor the Trustee shall have any obligation to make any Administrative Advance or Monthly
Payment Advances with respect to the Companion Loans). During the continuation of a Special Servicing Loan Event, the Special Servicer
shall give the Servicer and the Trustee not less than five Business Days’ written notice before the date on which the Servicer
is requested to make any Property Protection Advance with respect to the Whole Loan or Foreclosed Property; provided, however,
that only three Business Days’ written notice shall be required in respect of Property Protection Advances required to be
made on an urgent or emergency basis (which may include, without limitation, Property Protection Advances required to make tax
or insurance payments). In addition, the Special Servicer shall provide the Servicer

 

    -119-

     

    

 

with such information in its possession as
the Servicer may reasonably request to enable the Servicer to determine whether a requested Property Protection Advance would constitute
a Nonrecoverable Advance. Notwithstanding anything herein to the contrary, if the Special Servicer requests that the Servicer make
an Advance, the Servicer may conclusively rely on such request as evidence that such advance is not a Nonrecoverable Advance.

 

With respect to the payment of
insurance premiums and delinquent tax assessments, in the event that the Servicer determines that a Property Advance of such amounts
would constitute a Nonrecoverable Advance, the Servicer shall deliver notice of such determination to the Trustee, the Certificate
Administrator and the Special Servicer. The Servicer (with respect to the Whole Loan while it is not a Specially Serviced Loan)
and the Special Servicer (with respect to the Specially Serviced Loan or Foreclosed Property) shall determine (in the case of the
Special Servicer, with the reasonable assistance of the Servicer, if applicable) whether the payment of such amount (i) is necessary
to preserve the Property and (ii) would be in the best interests of the Certificateholders and the Companion Loan Holders, as a
collective whole (taking into account the relative subordination of the Trust A-B Note and the Non-Trust B Note) as if such Certificateholders
and the Companion Loan Holders constituted a single lender. If the Servicer or the Special Servicer, as applicable, determines
that the payment of such amount (i) is necessary to preserve the Property and (ii) would be in the best interests of the Certificateholders
and the Companion Loan Holders, the Special Servicer (in the case of a determination by the Special Servicer with respect to the
Specially Serviced Loan) shall direct the Servicer in writing to make such payment and the Servicer shall make such payment, to
the extent of available funds, from amounts in the Collection Account.

 

(c)          To the extent the Servicer fails to make an Advance that it is required to make under this Agreement, the Trustee shall
be required to make such Advance pursuant to Section 7.6. It is understood that the obligation of the Servicer and
the Trustee (pursuant to Section 7.6) to make such Advances is mandatory, subject to the limitations set forth in this
Agreement, and shall continue to apply with respect to the Trust Loan or the Whole Loan, as applicable, after any modification
or amendment of the Trust Loan or the Whole Loan, as applicable, pursuant to Section 3.24 hereof, beyond the Maturity
Date of the Trust Loan or the Whole Loan, as applicable, if a payment default shall have occurred on such date and through any
court appointed stay period or similar payment delay resulting from any insolvency of the Borrower or related bankruptcy, notwithstanding
any other provision of this Agreement, other than the requirement of recoverability, and shall continue, subject to the requirement
of recoverability, until the earlier of (i) the payment in full of the Trust Loan or the Whole Loan, as applicable, and (ii) the
date on which the Property becomes liquidated.

 

(d)          Interest on each Advance made by the Servicer or the Trustee shall accrue for each day that such Advance is outstanding
at a rate of interest equal to the Prime Rate (the “Advance Rate”) for each such day (or the most recent day
on which the Prime Rate was reported, if not reported on such day) (and with respect to Senior Companion Loan Advances, the rate
set forth in the Senior Companion Loan Pooling and Servicing Agreement) on the basis of a year of 360 days and the actual number
of days elapsed in a month. If the context requires, each reference to the reimbursement or payment of an Advance also includes,
whether or not specifically referred to, payment or reimbursement of interest thereon at the Advance Rate

 

    -120-

     

    

 

through but excluding
the date of payment or reimbursement. Interest on Advances, if unreimbursed, shall compound annually.

 

(e)          Notwithstanding any other provision in this Agreement, the Servicer or the Trustee shall be obligated to make an Advance
only to the extent that the Servicer or the Trustee, as applicable, has determined that such Advance, together with interest thereon
at the Advance Rate, would not constitute a Nonrecoverable Advance if made. The Trustee and the Servicer, in that order, shall
be entitled to reimbursement for any such Advances from the Collection Account and shall obtain such reimbursement in accordance
with Section 3.4(c). If the context requires, each reference to the reimbursement or payment of an Advance shall be
deemed to include, whether or not specifically referred to, payment or reimbursement of interest thereon at the Advance Rate through
but excluding the date of payment or reimbursement.

 

(f)          The determination by the Servicer or the Trustee that it has made a Nonrecoverable Advance or that any proposed Advance,
if made, would constitute a Nonrecoverable Advance, shall be evidenced by the delivery of an Officer’s Certificate to (i)
the Certificate Administrator, (ii) the Trustee in electronic format (if such determination is made by the Servicer), (iii) the
Servicer (if such determination is made by the Trustee), (iv) the Special Servicer, (v) the Companion Loan Holders, (vi) the Directing
Holder (during any Subordinate Control Period or Subordinate Consultation Period), (vii) the Senior Companion Loan Holder and (viii)
any Other Servicer, Other Special Servicer and Other Trustee under each related Other Pooling and Servicing Agreement (for purposes
of this clause (vii) only, promptly and in any event within two (2) Business Days after such determination or such longer
time period permitted by the Co-Lender Agreement) detailing the reasons for such determination with supporting documents attached.
Such Officer’s Certificate shall be made available to any Privileged Person by the Certificate Administrator by posting such
officer’s certificate to the Certificate Administrator’s Website in accordance with Section 8.14(b). The costs
of any appraisals, reports or surveys and other information requested by the Servicer or the Trustee establishing an Advance as
a Nonrecoverable Advance shall be treated as Trust Fund Expenses (and such expense shall be allocated in accordance with the allocation
provisions of the Co-Lender Agreement), payable from the Collection Account pursuant to Section 3.4(c), and shall constitute
a Property Protection Advance or Administrative Advance, as applicable, if paid by the Servicer or the Trustee from its funds.
Subject to Section 6.3, the Servicer’s determination of nonrecoverability in accordance with Accepted Servicing
Practices and the above provisions shall be conclusive and binding on the Trustee and the Trustee shall be entitled to rely conclusively
thereupon. The Trustee, in determining whether or not a proposed Advance would be a Nonrecoverable Advance, shall make such determination
in its reasonable business judgment.

 

(g)          With respect to the Whole Loan, the Servicer and the Trustee are not obligated to advance or pay (i) the principal
portion of any Balloon Payment with respect to the Trust Loan or Companion Loan (but are obligated to advance the related Assumed
Monthly Payment in respect of the Trust Loan only in accordance with the terms of this Agreement), (ii) any Default Interest,
(iii) amounts required to cure any damages resulting from Uninsured Causes (except as required pursuant to Section 3.12(c)),
any failure of the Property to comply with any applicable law, including any environmental law, or (except in connection with the
foreclosure or other acquisition of the Property in accordance with Section 3.12 upon the

 

    -121-

     

    

 

occurrence of a Loan Event
of Default) to investigate, test, monitor, contain, clean up, or remedy an environmental condition present at the Property, (iv) any
losses arising with respect to defects in the title to the Property, (v) any costs of capital improvements to the Property
other than those necessary to prevent an immediate or material loss to the Trust’s interest in the Property, (vi) any administrative
advances with respect to the Companion Loan or (vii) subordinated obligations, including the Junior Companion Loan and the Mezzanine
Loan.

 

3.24.          
Modifications of Loan Documents. (a)  (i) The Servicer (if no Special Servicing Loan Event has occurred
and is continuing) or the Special Servicer (if a Special Servicing Loan Event has occurred and is continuing) may, subject to the
rights of the Directing Holder, during any Subordinate Control Period or Subordinate Consultation Period, and of the Risk Retention
Consultation Party, modify, waive or amend any term of the Whole Loan if such modification, waiver or amendment (a) is consistent
with Accepted Servicing Practices and (b) does not either (i) cause either the Lower-Tier REMIC or the Upper-Tier REMIC to
fail to qualify as a REMIC under the Code or (ii) constitute a “significant modification” of the Whole Loan pursuant
to Treasury Regulations Section 1.860G-2(b) (and the Servicer or the Special Servicer, as applicable, may obtain and be entitled
to rely upon an Opinion of Counsel in connection with such determination). Notwithstanding anything herein to the contrary, in
no event may the Servicer or the Special Servicer permit an extension of the Maturity Date beyond the date that is five years prior
to the Rated Final Distribution Date. In connection with (i) the release of the Property or portion thereof from the lien of the
Mortgage or (ii) the taking of the Property or portion thereof by exercise of the power of eminent domain or condemnation, if the
Loan Documents require the Servicer or the Special Servicer, as applicable, to calculate the loan-to-value ratio of the remaining
Property, or the fair market value of the real property constituting the remaining Property, for purposes of REMIC qualification
of the Whole Loan, then, unless then permitted by the REMIC Provisions, such calculation shall exclude the value of personal property
and going concern value, if any, to the extent required by the REMIC Provisions.

 

(b)          All modifications, waivers or amendments of the Whole Loan shall be in writing and shall be effected in a manner consistent
with Accepted Servicing Practices and the REMIC Provisions. The Servicer or the Special Servicer, as applicable, shall notify the
Servicer (if notice is from the Special Servicer) Trustee, Certificate Administrator, the Companion Loan Holders, the Depositor,
during any Subordinate Control Period or Subordinate Consultation Period, the Directing Holder, and the Risk Retention Consultation
Party (unless the Risk Retention Consultation Party is a Borrower Related Party) in writing, of any modification, waiver or amendment
of any term of the Whole Loan and the date thereof, and shall deliver to the Certificate Administrator (with a copy to the Companion
Loan Holders) an original recorded counterpart of the agreement relating to such modification, waiver or amendment within ten (10)
Business Days following the execution and recordation thereof with a copy to the Servicer. In the event the Servicer or Special
Servicer, or a court of competent jurisdiction in connection with a workout or proposed workout of the Whole Loan, modifies the
interest rate applicable to the Trust Loan, the aggregate adverse economic effect of the modification (if any) shall be applied
to the Certificates, in reverse order of seniority. If the Whole Loan is modified, the Net Mortgage Rate shall not change for purposes
of distributions on the Certificates.

 

(c)          Subject to Section 3.27 of this Agreement, any modification of any Loan Documents that requires a Rating Agency Confirmation
pursuant to the Loan Documents, or any

 

    -122-

     

    

 

modification that would eliminate, modify or alter the requirement of obtaining such Rating
Agency Confirmation in the Loan Documents, shall not be made without the Servicer’s or the Special Servicer’s, as applicable,
first receipt of such Rating Agency Confirmation. Such Rating Agency Confirmation shall be obtained at the Borrower’s expense
in accordance with the Loan Agreement or, if not so provided in the Loan Agreement or if the Borrower does not pay, at the expense
of the Trust Fund.

 

(d)          Subject to Section 3.27 of this Agreement, prior to implementing any of clauses (vi), (vii), (viii), (ix), (x), (xi),
(xiii), (xvi) or (xviii) of the definition of Major Decision, the Servicer or the Special Servicer shall obtain a Rating Agency
Confirmation with respect to such Major Decision.

 

(e)          Notwithstanding the foregoing, the Servicer and (if a Special Servicing Loan Event is continuing) the Special Servicer may,
in accordance with Accepted Servicing Practices (without any Rating Agency Confirmation or consent of the Directing Holder), grant
the Borrower’s request for consent to subject the Property to a non-material easement, right of way or similar agreement
for utilities, access, parking, public improvements or another similar purpose and may consent to subordination of the Whole Loan
to such easement, right of way or similar agreement.

 

(f)          
Notwithstanding the foregoing, the Servicer shall not permit the substitution of the Property pursuant to the defeasance
provisions of the Whole Loan unless such defeasance complies with Treasury Regulations Section 1.860G-2(a)(8)(ii) and
the 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 Loan Documents, in an amount sufficient to make all
scheduled payments under the Notes (or defeased portion thereof) when due, (ii) a certificate of an Independent certified
public accountant to the effect that such substituted property will provide cash flows sufficient to meet all payments of interest
and principal (including payments at maturity) on the Notes in compliance with the requirements of the terms of the Loan Documents,
(iii) one or more Opinions of Counsel (at the expense of the Borrower) to the effect that the Trustee, on behalf of the Trust
Fund and the Companion Loan Holders, will have a first priority perfected security interest in such substituted Property; provided,
however, that, to the extent consistent with the Loan Documents, the Borrower shall pay the cost of any such opinion as
a condition to granting such defeasance, (iv) to the extent consistent with the Loan Documents, a single purpose entity shall act
as a successor mortgagor, if so required by the Rating Agencies, (v) to the extent permissible under the Loan Documents, the Servicer
shall use its reasonable efforts to require the Borrower 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 Loan Documents, the Servicer shall obtain,
at the expense of the Borrower, Rating Agency Confirmation from each Rating Agency and each rating agency relating to the Senior
Companion Loan Securities (subject to Section 3.27).

 

(g)          To the extent not required or permitted to be placed in a separate account, the Servicer shall deposit all payments received
by it from defeasance collateral substituted for the Property into the Collection Account and treat any such payments as payments
made on the Whole Loan in advance of its Loan Payment Date, and not as a prepayment of the Whole Loan.

 

    -123-

     

    

 

Notwithstanding anything
herein to the contrary, in no event shall the Servicer permit such amounts to be maintained in any Collection Account for a period
in excess of 365 days (or 366 days in the case of a leap year).

 

3.25.          
Servicer and Special Servicer May Own Certificates. The Servicer, the Special Servicer and any agent thereof in its
individual or any other capacity may become the owner or pledgee of Certificates with the same rights it would have if it were
not the Servicer or the Special Servicer or such agent except as otherwise provided herein subject to the restrictions on voting
set forth in the definition of Certificateholder.

 

3.26.          
Reserved.

 

3.27.         
Rating Agency Confirmation. (a)  Notwithstanding the terms of any Loan Documents or other provisions of
this Agreement, if any action under any Loan Documents or this Agreement requires a Rating Agency Confirmation or a written confirmation
from a Rating Agency that any action will not cause a downgrade, withdrawal or qualification of the then-current ratings on the
Certificates as a condition precedent to such action, if the party (the “Requesting Party”) seeking to obtain
such Rating Agency Confirmation or written confirmation has made a request to any Rating Agency for such Rating Agency Confirmation
or written confirmation and, within 10 Business Days of such request being sent to the applicable Rating Agency, such Rating Agency
has not replied to such request or has responded in a manner that indicates that such Rating Agency is either declining to review
such request or waiving the requirement for Rating Agency Confirmation or written confirmation, then such Requesting Party shall
be required to (i) confirm that the Rating Agency has received the Rating Agency Confirmation or written confirmation request,
and, if it has not, promptly request the related Rating Agency Confirmation or written confirmation again, (ii) if there is no
response to either such Rating Agency Confirmation or written confirmation request within 5 Business Days of such second request,
then (x) with respect to any condition in any Loan Document requiring such Rating Agency Confirmation or such written confirmation,
or any other matter under this Agreement relating to the servicing of the Whole Loan (other than as set forth in clause (y)
below), such requirement to obtain Rating Agency Confirmation or written confirmation from such Rating Agency for such action at
such time will not apply, and (y) with respect to a replacement of the Servicer or Special Servicer, such requirement to obtain
Rating Agency Confirmation or written confirmation from such Rating Agency for such action at such time will be deemed to be satisfied
(provided that granting such request is in accordance with Accepted Servicing Practices):  with respect to S&P,
the applicable replacement servicer or special servicer, as applicable, is listed on S&P’s Select Servicer List as a
U.S. Commercial Mortgage Master Servicer or U.S. Commercial Mortgage Special Servicer, as applicable, and with respect to Morningstar,
the applicable replacement servicer or special servicer, as applicable, (i) has a ranking by Morningstar higher than or equal to
“MOR CS3” as a master servicer or special servicer, as applicable or (ii)(A) such replacement servicer or special servicer
is acting as master servicer or special servicer, as applicable, in a commercial mortgage loan securitization that was rated by
a Rating Agency within the 12-month period prior to the date of determination and (B) Morningstar has not publicly cited servicing
concerns of the applicable replacement servicer or special servicer as the sole or material factor in any qualification, downgrade
or withdrawal of the then-current rating or ratings of one or more classes of such commercial mortgage backed securities.

 

    -124-

     

    

 

Any Rating Agency Confirmation
request made by the Servicer, Special Servicer, Certificate Administrator or Trustee, as applicable, pursuant to this Agreement,
shall be made in writing (which may be in electronic form), which writing shall contain a cover page indicating the nature of the
Rating Agency Confirmation request, and shall contain all back-up material the Servicer, Special Servicer, Certificate Administrator
or Trustee, as applicable, reasonably deems 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 8.14(b).

 

Promptly following the Servicer’s
or Special Servicer’s determination to take any action discussed in this Section 3.27(a) following any requirement
to obtain a Rating Agency Confirmation being considered satisfied, the Servicer or 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 post such notice on the 17g-5 Information Provider’s Website in accordance with Section 8.14(b).

 

(b)          For all other matters or actions requiring Rating Agency Confirmation and not specifically discussed in Section 3.27(a)
above, the applicable Requesting Party shall obtain and deliver Rating Agency Confirmation from each Rating Agency.

 

3.28.          
Certain Co-Lender Matters Relating to the Whole Loan.

 

(a)         
If, pursuant to Section 2.7, or Section 3.16 of this Agreement, the Trust Loan is, in its entirety,
purchased or repurchased from the Trust Fund, the subsequent holder thereof shall be bound by the terms of the Co-Lender Agreement
and shall assume the rights and obligations of the holder of the Trust Notes under the Co-Lender Agreement. All portions of the
Mortgage File and (to the extent provided under the Loan Purchase Agreement) other documents pertaining to the Trust Loan shall
be endorsed or assigned to the extent necessary or appropriate to the purchaser of the Trust Loan in its capacity as the holder
of the Trust Notes (as a result of such purchase, repurchase or substitution) and (except for the actual Trust Notes) on behalf
of the holders of the Non-Trust Notes that evidence the Companion Loan. Thereafter, such Mortgage File shall be held by the holder
of the Trust Notes or a custodian appointed thereby for the benefit thereof, on behalf of itself and the Companion Loan Holders
as their interests appear under the Co-Lender Agreement. If the related servicing file is not already in the possession of such
party, it shall be delivered to the master servicer or special servicer, as the case may be, under any separate servicing agreement
for the Whole Loan.

 

(b)          With respect to a Senior Companion Loan that becomes the subject of an “asset review” (or such analogous term
defined in the related Senior Companion Loan Pooling and Servicing Agreement) pursuant to the related Senior Companion Loan Pooling
and Servicing Agreement, the Servicer, the Special Servicer, the Trustee, the Certificate Administrator and the Custodian shall
reasonably cooperate with the asset representations reviewer or any other party to the Senior Companion Loan Pooling and Servicing
Agreement in connection with such asset review by providing the asset representations reviewer or such other requesting party with
any documents reasonably requested by the asset representations reviewer or such other requesting party, but only to the extent
(i) the requesting party or asset representations reviewer has not

 

    -125-

     

    

 

been able to obtain such documents from the Loan Seller or a
party to the Senior Companion Loan Pooling and Servicing Agreement and (ii) such documents are in the possession of the Servicer,
the Special Servicer, the Trustee, the Certificate Administrator or the Custodian, as the case may be. For the avoidance of doubt,
none of the Servicer, the Special Servicer, the Trustee, the Certificate Administrator or the Custodian shall (i) have further
obligations for such asset review or be bound by the related Senior Companion Loan Pooling and Servicing Agreement or shall (ii)
be obligated to provide such documents if providing such documents would, in its reasonable determination, be a violation of this
Agreement or the Co-Lender Agreement.

 

(c)          Notwithstanding anything in this Agreement to the contrary, but only to the extent required under the Co-Lender Agreement,
the Servicer or Special Servicer, as applicable, shall consult with the Companion Loan Holders with respect to any matters with
respect to the servicing of the Companion Loans to the extent required under the Co-Lender Agreement. The Servicer or Special Servicer,
as applicable, shall deliver reports and notices to the Companion Loan Holders to the extent required under the Co-Lender Agreement.

 

(d)         
The Servicer shall prepare, or cause to be prepared, on an ongoing basis, a statement setting forth:

 

(i)           the amount of the distribution from the Collection Account allocable to principal, separately identifying the amount of
balloon payments, principal prepayments made at the option of the Borrower or other principal prepayments (specifying the reason
therefor), net liquidation proceeds and foreclosure proceeds included therein and information on distributions made with respect
to the Whole Loan;

 

(ii)          the amount of the distribution from the Collection Account allocable to interest and the amount of Default Interest actually
received with respect to the Whole Loan;

 

(iii)          the amount of the distribution to the Companion Loan Holders, separately identifying the non-default interest, principal
and other amounts included therein, and if the distribution to the Companion Loan Holders is less than the full amount that would
be distributable to such Companion Loan Holders if there were sufficient amounts available therefor, the amount of the shortfall
and the allocation thereof between interest and principal and the amount of the shortfall, if any, under the Whole Loan;

 

(iv)        
the principal balance of each Note after giving effect to the distribution of principal as of the end of the related Collection
Period; and

 

(v)         
the amount of the servicing compensation paid to the Servicer and the Special Servicer with respect to the most recent Distribution
Date, showing separately the Servicing Fee, the Special Servicing Fee, the Work-out Fee and the Liquidation Fee.

 

Not later than each Remittance
Date, the Servicer shall make the foregoing statement available to the Companion Loan Holders by electronic means.

 

(e)          
At any time that a Companion Loan is included as an asset of a Senior Companion Loan Securitization Trust and provided that
the applicable parties hereto have

 

    -126-

     

    

 

received written notice (which may be by email) thereof including contact information for the
master servicer and special servicer with respect to such Senior Companion Loan Securitization Trust, all notices, reports, information
or other deliverables required to be delivered to the related Companion Loan Holder pursuant to this Agreement or the Co-Lender
Agreement shall be delivered to the master servicer and special servicer of such Senior Companion Loan Securitization Trust (who
then may forward such items to the party entitled to receive such items as and to the extent provided in the related Senior Companion
Loan Pooling and Servicing Agreement) and, when so delivered to such master servicer and special servicer, the party hereto that
is obligated under this Agreement or the Co-Lender Agreement to deliver such notices, reports, information or other deliverables
shall be deemed to have satisfied its delivery obligations with respect to such items hereunder or under the Co-Lender Agreement.

 

3.29.       
Additional Matters with Respect to the Whole Loan.

 

(a)         
In the event that only the Loan Seller repurchases one but not all of the Trust Notes (each, a “Repurchased Note”)
in accordance with Section 2.7 hereof and Section 8 of the Loan Purchase Agreement:

 

(i)          
The provisions of this Section 3.29 shall apply with respect to the servicing and administration of the Whole
Loan (and the Loan Seller has agreed to such provisions in the Loan Purchase Agreement) until such time as all of the Trust Notes
are repurchased or otherwise no longer part of the Trust, and the related successor holders thereof and the Companion Loan Holders
have entered into a servicing agreement with respect to the Whole Loan in accordance with the Co-Lender Agreement.

 

(ii)         
Custody of the respective Loan Documents shall be held exclusively by the Custodian, and record title under the respective
Loan Documents shall be held exclusively by the Trustee, on behalf of the Certificateholders, as provided under this Agreement
(subject to the rights of the Companion Loan Holders with respect to the Companion Loans), except that the Loan Seller shall hold
and retain title to its original Repurchased Note and any related endorsements thereof.

 

(iii)        
Payments from the Borrower or any other amounts received with respect to each Note shall be collected as provided in this
Agreement by the Servicer and shall be applied to each Note in accordance with this Co-Lender Agreement and this Agreement, subject
to Section 3.29(a)(iv). Payments or any other amounts received with respect to the related Repurchased Note shall be
held in trust by the Servicer for the benefit of the Loan Seller and remitted (net of its pro rata share of any Servicing
Fees, Special Servicing Fees, Certificate Administrator Fees (including that portion of the Certificate Administrator Fees that
represents the Trustee Fees, which are payable to the Trustee) and any Trust Fund Expenses) to the Loan Seller or its designee
by the Servicer on or before each Distribution Date pursuant to instructions provided by the Loan Seller and deposited and applied
in accordance with this Agreement, subject to Section 3.29(a)(iv). In the event that the Property becomes Foreclosed
Property, payments or any other amounts received with respect to the Whole Loan shall be collected and shall be applied pro
rata to each related Note (net of its pro rata share of any Servicing Fees, Special Servicing Fees, Certificate Administrator
Fees (including that portion of the Certificate

 

    -127-

     

    

 

Administrator Fees that represents the Trustee Fees, which are payable to the Trustee),
CREFC® Intellectual Property Royalty License Fees, and any other Trust Fund Expenses) based on its respective principal balance,
subject to Section 3.29(a)(iv).

 

(iv)        
In the event that the Servicer or the Special Servicer, as applicable, receives an aggregate payment of less than the aggregate
amount due under the Whole Loan at any particular time, the Loan Seller shall be entitled to receive from the Servicer an amount
equal to the Loan Seller’s allocable share (based upon its respective principal balance) of such payment as determined in
accordance with the terms of the Co-Lender Agreement and this Agreement. All expenses, losses and shortfalls including, without
limitation, losses of principal or interest, Advances that have been declared Nonrecoverable Advances, interest on Advances, Special
Servicing Fees, Work-out Fees and Liquidation Fees (including any such fees related to the related Notes) and other Trust Fund
Expenses, will be allocated between the holders of the Notes in accordance with the Co-lender Agreement, provided, however,
such allocation shall not limit the Trustee’s, Certificate Administrator’s, Servicer’s or Special Servicer’s
rights to full reimbursement of such expenses, losses and shortfalls under this Agreement.

 

(v)         
For so long as the Whole Loan shall be serviced by the Servicer or the Special Servicer in accordance with this Agreement,
the Servicer or the Special Servicer, as applicable, on behalf of the holders thereof shall administer the Whole Loan consistent
with the terms of this Agreement. The Loan Seller shall not be permitted to terminate the Servicer or Special Servicer as servicer
or special servicer of the related Repurchased Note. All rights of the mortgagee under the Whole Loan will be exercised by the
Servicer or Special Servicer, on behalf of the Trust to the extent of its interest therein, the Companion Loan Holders and on behalf
of the Loan Seller to the extent of its interest therein (as a collective whole) in accordance with this Agreement.

 

(vi)        
Funds collected by the Servicer or the Special Servicer, as applicable, and applied to the Notes shall be deposited and
disbursed in accordance with the provisions hereof. Compensation shall be paid to the Trustee, Certificate Administrator, Servicer,
Special Servicer and CREFC® with respect to the related Repurchased Note as provided in this Agreement. None of
the Trustee, the Certificate Administrator, the Servicer or the Special Servicer shall have any obligation to make any Monthly
Payment Advance on the Trust Loan with respect to the related Repurchased Note. The Servicer, Certificate Administrator and the
Special Servicer shall have no reporting requirement with respect to the related Repurchased Note other than that the holder of
the related Repurchased Note, subject to delivery by such holder of an Investor Certification, shall be entitled to receive any
and all reports and have access to any and all information that a Certificateholder would otherwise have under the terms of this
Agreement.

 

(vii)       
If any Note is considered a Specially Serviced Loan, then each Note shall be a Specially Serviced Loan under this Agreement
and the Special Servicer shall cause such related Repurchased Note to be specially serviced for the benefit of the Loan Seller
in accordance with the terms and provisions set forth in this Agreement and shall be entitled to any Special Servicing Fee, Work-out
Fee or Liquidation Fee that would be payable to the Special Servicer under this Agreement.

 

    -128-

     

    

 

(viii)      
The Repurchased Note shall not be considered a Trust Note for purposes of exercising any of the consent or consultation
provisions of the Co-Lender Agreement but shall be entitled to the consultation rights granted to holders of Non-Trust A Note.

 

(b)         
If (A) the Servicer pays any amount to the Loan Seller pursuant hereto 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 Notes and (B) such payment is not received
or collected by the Servicer, then the Loan Seller will promptly on demand by the Servicer return such amount to the Servicer.
If the Servicer determines at any time that any amount received or collected by the Servicer in respect of the Whole Loan must
be returned to the Borrower or paid to any other Person or entity pursuant to any insolvency law or otherwise, notwithstanding
any other provision of this Agreement, the Servicer shall not be required to distribute any portion thereof to the Loan Seller,
and the Loan Seller will promptly on demand by the Servicer repay, which obligation shall survive the termination of this Agreement,
any portion thereof that the Servicer may have distributed to the Loan Seller, together with interest thereon at such rate, if
any, as the Servicer may pay to the Borrower or such other Person or entity with respect thereto.

 

(c)          
Subject to this Agreement, the Servicer, or the Special Servicer, as applicable, on behalf of the holders of the Repurchased
Note, shall have the exclusive right and obligation to (i) administer, service and make all decisions and determinations regarding
the Whole Loan, and (ii) enforce the Loan Documents as provided hereunder. Without limiting the generality of the preceding sentence,
the Servicer, or Special Servicer, as applicable, may provide consent to any action or inaction under the Loan Documents, 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 Borrower on or any guarantor of the
Whole Loan without the consent of the Loan Seller, subject, however, to Section 3.24.

 

(d)          
In taking or refraining from taking any action permitted hereunder, the Servicer and the Special Servicer shall each be
subject to the same degree of care with respect to the administration and servicing of the Whole Loan as is consistent with this
Agreement; and shall only be liable to the Loan Seller to the same extent as set forth herein as it is liable to the Trust.

 

(e)          
In the event that the Trustee or the Servicer has made a Property Protection Advance or an Administrative Advance with respect
to the Whole Loan that would otherwise be reimbursable to such advancing party under this Agreement, and such Advance is determined
to be a Nonrecoverable Advance, the Loan Seller shall reimburse the Trustee, the Certificate Administrator, the Servicer or the
Special Servicer, as applicable, in an amount equal to its pro rata share (based upon its respective principal balance)
of such Nonrecoverable Advance and accrued interest thereon at the Advance Rate. To the extent that the Loan Seller reimburses
any such Nonrecoverable Advances and such amounts are subsequently recovered by the Trust, the Loan Seller shall receive a reimbursement
from such recovery to the same extent. If less than 100% of the Nonrecoverable Advances are reimbursed by or on behalf of the Borrower,
the Servicer shall reimburse the Trust and the Loan Seller on a pro rata basis from such amounts received from the Borrower.
Notwithstanding anything herein to the contrary, including, but not limited to the Loan Seller’s reimbursement obligation
described herein, the

 

    -129-

     

    

 

Trustee or Servicer shall have a right to reimbursement of any amounts advanced under Section 3.4(d)
for the full Nonrecoverable Advance and interest thereon at the Advance Rate. Notwithstanding anything to the contrary contained
herein, the total liability of the Loan Seller shall not exceed an amount equal to its pro rata share (based upon its respective
principal balance) of the aggregate Whole Loan obligations.

 

(f)          
The 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.

 

(g)         
The Servicer and the Special Servicer shall, in connection with their servicing and administrative duties under this Agreement,
exercise efforts consistent with the Accepted Servicing Practices to execute and deliver, on behalf of the Loan Seller as a holder
of a pari passu interest in the Whole Loan, any and all documents and instruments necessary to maintain the lien created
by the Mortgage or other security document related to the Whole Loan or the Property and related collateral, any and all modifications,
waivers, amendments or consents to or with respect to the 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 Property all in accordance with, and subject to, the terms of this Agreement. The Loan Seller agrees to furnish,
or cause to be furnished, to the Servicer and the Special Servicer any powers of attorney or other documents necessary or appropriate
to enable the Servicer or the Special Servicer, as the case may be, to carry out its servicing and administrative duties under
this Agreement related to the Whole Loan; provided, however, that the Loan Seller shall not be liable, and shall
be indemnified by the Servicer or the Special Servicer, as applicable, for any negligence with respect to, or misuse of, any such
power of attorney by the Servicer or the Special Servicer, as the case may be; and further provided that the Servicer or the Special
Servicer, without the written consent of the Loan Seller, shall not initiate any action in the name of the Loan Seller without
indicating its representative capacity that actually causes the Loan Seller to be registered to do business in any state.

 

(h)         
The Loan Seller agrees to deliver to the Servicer or the Special Servicer, as applicable the Loan Documents related to the
related Repurchased Note or related Repurchased Notes, as applicable, any receipt 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 Property or
to any legal action or to enforce any other remedies or rights provided by the Note(s) or the Mortgage or otherwise available at
law or equity with respect to the related Repurchased Note.

 

The rights granted to the Loan
Seller under this Section 3.29 shall in all respects be subject to the general rights, indemnification in favor of
the Certificate Administrator, Trustee, Servicer and Special Servicer, protections, limitations on liability and immunities granted
to the parties in this Agreement (including, but not limited to, Section 6.3) and this Section 3.29 shall
not be construed to limit such indemnification in favor of the Certificate Administrator, Trustee, Servicer and Special Servicer
rights, protections, limitations on liability and immunities which shall apply to all the Notes, including the Repurchased Note.

Losses in an amount equal to the amount of principal or reimbursement of Realized Losses actually distributable to its respective
Related Certificates as provided in Sections 4.1(a) and 4.1(g). On each Distribution Date, each Uncertificated
Lower-Tier Interest shall be deemed to receive distributions in respect of interest in an amount equal to the sum of the Interest
Distribution Amount and Interest Shortfall in respect of its Related Certificates and in the case of the Class LA, Class LB
and Class LC Uncertificated Interests, the Interest Distribution Amount and Interest Shortfall in respect of the Class X Strip
Rate of the Related Class X Component, in each case, to the extent actually distributable thereon as provided in Section 4.1(a).
Amounts distributable pursuant to this paragraph and any Yield Maintenance Premiums distributed pursuant to Section 4.3(b)
are referred to herein collectively as the “Lower-Tier Distribution Amount”, and shall be deemed to be made
by the Certificate Administrator by being deemed to deposit such Lower-Tier Distribution Amount into the Upper-Tier Distribution
Account on each Distribution Date.

 

As of any date, the principal
balance of each Uncertificated Lower-Tier Interest shall equal its Lower-Tier Principal Amount. The Pass-Through Rate
with respect to each Uncertificated Lower-Tier Interest shall be the rate per annum set forth in the Introductory Statement
hereto.

 

    -137-

     

    

 

Any amount that remains in the
Lower-Tier Distribution Account on each Distribution Date after distribution of the Lower-Tier Distribution Amount shall
be distributed to the Holders of the Class R Certificates (in respect of the Class LT-R Interest, but only to the extent
of the amount remaining in the Lower-Tier Distribution Account, if any).

 

Distributions to Holders of Class R
Certificates from the Lower-Tier Distribution Account (in respect of the Class LT-R Interest) and from the Upper-Tier Distribution
Account (in respect of the Class UT-R Interest) and to each other Certificateholder from the Regular Interest Distribution Account
on each Distribution Date shall be made by the Certificate Administrator to each Certificateholder of record on the related Record
Date (other than as provided in Section 10.1 in respect of the final distribution), by wire transfer in immediately available
funds to the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor; provided that the Certificate Administrator has received appropriate wire transfer instructions therefrom, or
by check by first class mail to the address set forth therefor in the Certificate Register if wiring instructions have not been
received at least five (5) Business Days prior to the Distribution Date.

 

(c)         
All amounts distributable to a Class of Certificates pursuant to Section 4.1(b) on each Distribution Date shall
be allocated pro rata among the outstanding Certificates in each such Class based on their respective Percentage Interests.
Such distributions shall be made on each Distribution Date to each Certificateholder of record at the close of business on the
related Record Date by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other
entity located in the United States and having appropriate facilities therefor provided that the Certificate Administrator
has received appropriate wire transfer instructions therefrom, or by check by first class mail to the address set forth therefor
in the Certificate Register if wiring instructions have not been received at least five (5) Business Days prior to the Distribution
Date. The final distribution on each Certificate shall be made in like manner, but only upon presentment and surrender of such
Certificate at the location specified by the Certificate Administrator in the notice to Certificateholders of such final distribution.

 

(d)         
The Certificate Administrator shall, as soon as reasonably possible after notice thereof by the Servicer to the Certificate
Administrator that the final distribution with respect to any Class of Certificates is expected to be made, post a notice
on the Certificate Administrator’s Website pursuant to Section 8.14(b), deliver such notice to the 17g-5 Information
Provider (who shall post such notice on the 17g-5 Information Provider’s Website pursuant to Section 8.14(b)) and
mail to each Holder of such Class of Certificates on such date a notice to the effect that:

 

(i)          
the Certificate Administrator reasonably expects based upon information previously provided to it that the final distribution
with respect to such Class of Certificates shall be made on such Distribution Date, but only upon presentation and surrender
of such Certificates at the office of the Certificate Administrator therein specified; and

 

    -138-

     

    

 

(ii)         
if such final distribution is made on such Distribution Date, no interest shall accrue on such Certificate from and after
the Certificate Interest Accrual Period related to such Distribution Date.

 

(e)         
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 in trust for the benefit
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section
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 to
receive the final distribution with respect thereto. If within one year after the second notice not all of such Certificates shall
have been surrendered for cancellation, the Certificate Administrator may, directly or through an agent, take appropriate steps
to contact the remaining non-tendering Certificateholders concerning surrender of their Certificates. The costs and expenses of
holding such funds in trust and of contacting such Certificateholders shall be paid out of such funds. All such amounts shall be
held by the Certificate Administrator in trust in accordance herewith until the expiration of a two-year period following such
second notice, notwithstanding any termination of the Trust Fund. Subject to applicable state escheatment laws, if within two years
after the second notice any such Certificates shall not have been surrendered for cancellation, the Certificate Administrator shall
hold all amounts distributable to the Holders thereof for the benefit of such Holders until the earlier of (i) its termination
as Certificate Administrator hereunder and the transfer of such amounts to a successor Certificate Administrator and (ii) the
termination of the Trust Fund, at which time such amounts shall, subject to applicable law, be distributed to the Depositor. No
interest shall accrue or be payable to any Certificateholder on any amount held in trust hereunder or 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 4.1(e). Any such amounts transferred to the Certificate Administrator shall not be invested.

 

(f)          
The Certificate Administrator shall be responsible for the calculations with respect to distributions from the Trust so
long as the Trust Fund has not been terminated in accordance with this Agreement. The Certificate Administrator shall have no duty
to recompile, recalculate or verify the accuracy of information provided to it by the Servicer pursuant to Section 3.18(a)
and, in the absence of manifest error in such information, may conclusively rely upon it.

 

(g)         
On each Distribution Date, Realized Losses with respect to the Trust Loan shall be allocated to reduce the Certificate Balance
of each Class of Regular Interests (other than the Class X-A and Class X-B Regular Interests) in the following order:

 

first, to the Class E
Regular Interest;

 

second, to the Class D
Regular Interest;

 

third, to the Class C
Regular Interest;

 

    -139-

     

    

 

fourth, to the Class B
Regular Interest; and

 

fifth, to the Class A
Regular Interest; in each case until the Certificate Balance of the related Class has been reduced to zero.

 

On any Distribution Date, allocations
of Realized Losses to any Class of Regular Interests (other than the Class X-A and Class X-B Regular Interests) (or portion thereof)
that corresponds to a Class X-A Component or Class X-B Component shall result in a corresponding reduction in the Notional Amount
of the Class X-A Regular Interest or Class X-B Regular Interest, as applicable, on the same Distribution Date. Allocations of Realized
Losses to any Class of Regular Interests (other than the Class X-A and Class X-B Regular Interests) shall be deemed to result in
a corresponding reduction of the Lower-Tier Principal Amount of the Related Uncertificated Lower-Tier Interest.

 

Any such Realized Losses in respect
of:

 

(A)        
the Class A Regular Interest shall be further allocated to the Class A Certificates, the Class V1-A Certificates and the
Class V2 Certificates, pro rata in proportion to the Class A Percentage Interest, the Class V1-A Percentage Interest and
the Class V2 Percentage Interest, respectively;

 

(B)         
the Class B Regular Interest shall be further allocated to the Class B Certificates, the Class V1-B Certificates and the
Class V2 Certificates, pro rata in proportion to the Class B Percentage Interest, the Class V1-B Percentage Interest and
the Class V2 Percentage Interest, respectively;

 

(C)         
the Class C Regular Interest shall be further allocated to the Class C Certificates, the Class V1-C Certificates and the
Class V2 Certificates, pro rata in proportion to the Class C Percentage Interest, the Class V1-C Percentage Interest and
the Class V2 Percentage Interest, respectively;

 

(D)        
the Class D Regular Interest shall be further allocated to the Class D Certificates, the Class V1-D Certificates and the
Class V2 Certificates, pro rata in proportion to the Class D Percentage Interest, the Class V1-D Percentage Interest and
the Class V2 Percentage Interest, respectively; and

 

(E)         
the Class E Regular Interest shall be further allocated to the Class E Certificates, the Class V1-E Certificates and the
Class V2 Certificates, pro rata in proportion to the Class E Percentage Interest, the Class V1-E Percentage Interest and
the Class V2 Percentage Interest, respectively.

 

To the extent any Realized Losses
are subsequently recovered, the amount of such recovery shall be reimbursed to the Certificateholders in the following order: first,
to the Class A Regular Interest, second, to the Class B Regular Interest, third, to the Class C Regular
Interest, fourth, to the Class D Regular Interest, and fifth, to the Class E Regular Interest (and the
Related Uncertificated Lower-Tier Interests), in each case up to the amount of any Realized Losses, if any, that have been allocated
to such Class.

4.2.          
Withholding Tax.   (a) Notwithstanding any other provision of this Agreement, the Certificate Administrator
shall comply with all federal withholding requirements with respect to payments to Certificateholders or any payee that the Certificate
Administrator reasonably believes are applicable under the Code. The consent of Certificateholders shall not be required for any
such withholding. In the event the Certificate Administrator withholds any amount from interest payments or advances thereof to
any Certificateholder or payee pursuant to federal withholding requirements, amounts so withheld shall be treated as having been
entirely distributed to such Certificateholder or payee, and the Certificate Administrator shall indicate the amount withheld to
such Certificateholder or payee through a report.

 

(b)          Each
Beneficial Owner and Certificateholder, by the purchase of a Certificate or its acceptance of a beneficial interest therein, acknowledges
that interest on the Certificates will be treated as United States source interest, and, as such, United States withholding tax
may apply. Each such Beneficial Owner and Certificateholder further agrees, upon request, to provide any certifications that may
be required under applicable law, regulations or procedures to evidence its status for United States withholding tax purposes and
understands that if it ceases to satisfy the foregoing requirements or provide requested documentation, payments to it under the
Certificates may be subject to United States withholding tax (without any corresponding gross-up). Without limiting the foregoing,
if a payment made under this Agreement would be subject to United States federal withholding tax imposed by FATCA if the recipient
of such payment were to fail to comply with FATCA (including the requirements of Sections 1471(b) or 1472(b) of the Code, as applicable),
such recipient shall deliver to the Certificate Administrator, with a copy to the Trustee, at the time or times prescribed by the
Code and at such time or times reasonably requested by the Certificate Administrator or the Trustee, such documentation prescribed
by the Code (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested
by the Trustee or the Certificate Administrator to comply with their respective obligations under FATCA, to determine that such
recipient has complied with such recipient’s obligations under FATCA, or to determine the amount to deduct and withhold from
such payment.

 

4.3.

longer willing or able to discharge properly its responsibilities as depository with respect to the Global 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 90 days of such notice or (ii) the Certificate Administrator or 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 Certificate Administrator or the Trustee,
as the case may be, 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 Certificates be issued to beneficial owners of a Temporary Regulation S Global 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 Global Certificates and upon surrender by the Depository of any Global Certificate of such Class and receipt
from the Depository of instructions for reregistration, the Certificate Registrar shall issue Certificates of such Class in the
form of Definitive Certificates (bearing, in the case of a Definitive Certificate issued for a Rule 144A Global Certificate,
the same legends regarding transfer restrictions borne by such Global Certificate), and thereafter the Certificate Registrar shall
recognize the holders of such Definitive Certificates as Certificateholders under this Agreement.

 

5.3.              
Registration of Transfer and Exchange of Certificates. (a)  The Certificate Administrator shall keep or
cause to be kept at the Corporate Trust Office books (the “Certificate Register”) in which, subject to such
reasonable regulations as it may prescribe, the Certificate Administrator shall provide for the registration of Certificates and
of transfers and exchanges of Certificates as herein provided (the Certificate Administrator, in such capacity, being the “Certificate
Registrar”). In such capacity, the Certificate Administrator shall be responsible for, among other things, (i) maintaining
the Certificate Register and a record of the aggregate holdings of Certificates of each Class represented by a Temporary Regulation S
Global Certificate, a Regulation S Global Certificate and a Rule 144A Global Certificate and accepting Certificates for
exchange and registration of transfer and (ii) transmitting to the

Depositor, the Trustee, the Servicer and the Special Servicer
any notices from the Certificateholders.

 

(b)         
Subject to the restrictions on transfer set forth in this Article 5, upon surrender for registration of transfer of any
Certificate, the Certificate Registrar 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.

 

(c)         
Rule 144A Global Certificate to Temporary Regulation S Global Certificate. If a holder of a beneficial
interest in the Rule 144A Global Certificate deposited with the Certificate Registrar as custodian for the Depository wishes
at any time to exchange its interest in such Rule 144A Global Certificate for an interest in the Temporary Regulation S
Global Certificate of the same Class, or to transfer its interest in such Rule 144A Global Certificate to a Person who is
required to take delivery thereof in the form of an interest in the Temporary Regulation S Global Certificate of the same
Class, such holder may, subject to the rules and procedures of the Depository, exchange or cause the exchange of such interest
for an equivalent beneficial interest in such Temporary Regulation S Global Certificate. Upon receipt by the Certificate Registrar,
as registrar, at its office designated in Section 5.7 hereof, of (1) instructions given in accordance with the
Depository’s procedures from a Depository Participant directing the Certificate Registrar to credit, or cause to be credited,
a beneficial interest in the Temporary Regulation S Global Certificate in an amount equal to the beneficial interest in the
Rule 144A Global Certificate to be exchanged, (2) a written order given in accordance with the Depository’s procedures
containing information regarding the Euroclear or Clearstream account to be credited with such increase and the name of such account
and (3) a certificate in the form of Exhibit C hereto given by the holder of such beneficial interest stating
that the transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Certificates
and pursuant to and in accordance with Regulation S, then the Certificate Registrar shall instruct the Depository to reduce,
or cause to be reduced, the Certificate Balance of the Rule 144A Global Certificate and to increase, or cause to be increased,
the Certificate Balance of the Temporary Regulation S Global Certificate by the aggregate Certificate Balance of the beneficial
interest in the Rule 144A Global Certificate to be exchanged, to credit or cause to be credited to the account of the Person
specified in such instructions (who shall be the agent member of Euroclear or Clearstream, or both) a beneficial interest in the
Temporary Regulation S Global Certificate equal to the reduction in the Certificate Balance of the Rule 144A Global Certificate,
and to debit, or cause to be debited, from the account of the Person making such exchange or transfer the beneficial interest in
the Rule 144A Global Certificate that is being exchanged or transferred.

 

(d)          
Rule 144A Global Certificate to Regulation S Global Certificate. If a holder of a beneficial interest in
the Rule 144A Global Certificate deposited with the Certificate Registrar as custodian for the Depository wishes at any time
to exchange its interest in such Rule 144A Global Certificate for an interest in the Regulation S Global Certificate
of the same Class, or to transfer its interest in such Rule 144A Global Certificate to a Person who is required to take delivery
thereof in the form of an interest in a Regulation S Global Certificate, such holder may, subject to the rules and procedures
of the Depository, exchange, or cause the exchange of, such interest for an equivalent beneficial interest in such Regulation S
Global Certificate. Upon receipt by the Certificate Registrar, as registrar, at its office designated in

 

    -152-

     

    

 

Section 5.7
hereof, of (1) instructions given in accordance with the Depository’s procedures from a Depository Participant directing
the Certificate Registrar to credit or cause to be credited a beneficial interest in the Regulation S Global Certificate in
an amount equal to the beneficial interest in the Rule 144A Global Certificate to be exchanged, (2) a written order given
in accordance with the Depository’s procedures containing information regarding the participant account of the Depository
to be credited with such increase and (3) a certificate in the form of Exhibit D hereto given by the holder of
such beneficial interest stating (A) that the transfer of such interest has been made in compliance with the transfer restrictions
applicable to the Global Certificates and pursuant to and in accordance with Regulation S, (B) that the Certificate being
transferred is not a “restricted security” as defined in Rule 144 under the Act or (C) that the transferee
is otherwise entitled to hold its interest in the applicable Certificates in the form of an interest in the Regulation S Global
Certificate, without any registration of such Certificates under the Act (in which case such certificate shall enclose an Opinion
of Counsel to such effect and such other documents as the Certificate Registrar may reasonably require), then the Certificate Registrar
shall instruct the Depository to reduce, or cause to be reduced, the Certificate Balance of the Rule 144A Global Certificate
and to increase, or cause to be increased, the Certificate Balance of the Regulation S Global Certificate by the aggregate
Certificate Balance of the beneficial interest in the Rule 144A Global Certificate to be exchanged, to credit or cause to
be credited to the account of the Person specified in such instructions a beneficial interest in the Regulation S Global Certificate
equal to the reduction in the Certificate Balance of the Rule 144A Global Certificate, and to debit, or cause to be debited,
from the account of the Person making such exchange or transfer the beneficial interest in the Rule 144A Global Certificate
that is being exchanged or transferred.

 

(e)          
Temporary Regulation S Global Certificate or Regulation S Global Certificate to Rule 144A Global Certificate.
If a holder of a beneficial interest in a Temporary Regulation S Global Certificate or Regulation S Global Certificate
deposited with the Certificate Registrar as custodian for the Depository wishes at any time to exchange its interest in such Temporary
Regulation S Global Certificate or Regulation S Global Certificate for an interest in the Rule 144A Global Certificate
of the same Class, or to transfer its interest in such Temporary Regulation S Global Certificate or Regulation S Global
Certificate to a Person who is required to take delivery thereof in the form of an interest in the Rule 144A Global Certificate,
such holder may, subject to the rules and procedures of Euroclear or Clearstream, as the case may be, and the Depository, exchange
or cause the exchange of such interest for an equivalent beneficial interest in the Rule 144A Global Certificate of the same
Class. Upon receipt by the Certificate Registrar, as registrar, at its office designated in Section 5.7 hereof, of
(1) instructions from Euroclear or Clearstream, if applicable, and the Depository, directing the Certificate Registrar, as
registrar, to credit or cause to be credited a beneficial interest in the Rule 144A Global Certificate equal to the beneficial
interest in the Temporary Regulation S Global Certificate or Regulation S Global Certificate to be exchanged, such instructions
to contain information regarding the participant account with the Depository to be credited with such increase, (2) with respect
to a transfer of an interest in the Regulation S Global Certificate, information regarding the participant account of the
Depository to be debited with such decrease and (3) with respect to a transfer of an interest in the Temporary Regulation S
Global Certificate (but not the Regulation S Global Certificate) for an interest in the Rule 144A Global Certificate,
a certificate in the form of Exhibit E hereto given by the holder of such beneficial interest and stating that the
Person transferring such interest in the Temporary Regulation S Global Certificate reasonably believes that the Person acquiring

 

    -153-

     

    

 

such interest in the Rule 144A Global Certificate is a QIB and is obtaining such beneficial interest in a transaction meeting
the requirements of Rule 144A, then the Certificate Registrar shall instruct the Depository to reduce, or cause to be reduced,
the Certificate Balance of the Temporary Regulation S Global Certificate or Regulation S Global Certificate and to increase,
or cause to be increased, the Certificate Balance of the Rule 144A Global Certificate by the aggregate Certificate Balance
of the beneficial interest in the Temporary Regulation S Global Certificate or Regulation S Global Certificate to be
exchanged, and the Certificate Registrar shall instruct the Depository, concurrently with such reduction, to credit, or cause to
be credited, to the account of the Person specified in such instructions, a beneficial interest in the Rule 144A Global Certificate
equal to the reduction in the Certificate Balance of the Temporary Regulation S Global Certificate or Regulation S Global
Certificate and to debit, or cause to be debited, from the account of the Person making such transfer the beneficial interest in
the Temporary Regulation S Global Certificate or Regulation S Global Certificate that is being transferred.

 

(f)          
Temporary Regulation S Global Certificate to Regulation S Global Certificate. Interests in a Temporary
Regulation S Global Certificate as to which the Certificate Registrar has received from Euroclear or Clearstream, as the case
may be, a certificate (a “Non-U.S. Beneficial Ownership Certification”) to the effect that Euroclear or
Clearstream, as applicable, has received a certificate substantially in the form of Exhibit F hereto from the holder
of a beneficial interest in such Temporary Regulation S Global Certificate, shall be exchanged after the Restricted Period,
for interests in the Regulation S Global Certificate of the same Class. The Certificate Registrar shall effect such exchange
by delivering to the Depository for credit to the respective accounts of such holders, a duly executed and authenticated Regulation S
Global Certificate, representing the aggregate Certificate Balance of interests in the Temporary Regulation S Global Certificate
initially exchanged for interests in the Regulation S Global 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 Global Certificate. Upon any exchange of interests
in the Temporary Regulation S Global Certificate for interests in the Regulation S Global Certificate, the Certificate
Registrar shall endorse the Temporary Regulation S Global Certificate to reflect the reduction in the Certificate Balance
represented thereby by the amount so exchanged and shall endorse the Regulation S Global 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
Global Certificate, and the Certificates evidenced thereby, shall in all respects be entitled to the same benefits under this Agreement
as the Regulation S Global Certificate and Rule 144A Global Certificate authenticated and delivered hereunder.

 

(g)         
Non-Book Entry Certificate to Global Certificate. If a holder of a Non-Book Entry Certificate (other than a Class
R Certificate) wishes at any time to exchange its interest in such Non-Book Entry Certificate for an interest in a Global 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 Global 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 Global Certificate of the same Class. Upon receipt by the Certificate

 

    -154-

     

    

 

Registrar, as registrar, at its
office designated in Section 5.7 hereof, 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 Global 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 G hereto (in the event that the applicable
Global Certificate is the Temporary Regulation S Global Certificate), in the form of Exhibit H hereto (in the
event that the applicable Global Certificate is the Regulation S Global Certificate) or in the form of Exhibit I
hereto (in the event that the applicable Global Certificate is the Rule 144A Global 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 Global Certificate by
the aggregate Certificate Balance of the portion of the Non-Book Entry Certificate to be exchanged and to credit, or cause to be
credited, to the account of the Person specified in such instructions a beneficial interest in the applicable Global Certificate
equal to the Certificate Balance of the portion of the Non-Book Entry Certificate so canceled.

 

(h)         
Non-Book Entry Certificates on Initial Issuance Only. Subject to the issuance of Definitive Certificates, if and
when permitted by Section 5.2(d), and no Non-Book Entry Certificate shall be issued to a transferee of an interest
in any Rule 144A Global Certificate, Temporary Regulation S Global Certificate or Regulation S Global Certificate
(or any portion thereof).

 

(i)          
Transfers of RR Interest. At all times, if a transfer of all or a portion of the RR Interest is to be made, then
the Certificate Registrar shall refuse to register such transfer unless it receives (and, upon receipt, may conclusively rely upon)
(i) a certification from such Certificateholder’s prospective transferee substantially in the form attached hereto as Exhibit
M-4, which such certification must be countersigned by the Retaining Sponsor and Depositor with a medallion stamp guarantee
of the Retaining Sponsor and (ii) a certification from the Certificateholder desiring to effect such transfer substantially in
the form attached hereto as Exhibit M-5, which such certification must be countersigned by the Retaining Sponsor and the
Depositor with a medallion stamp guarantee of the Retaining Sponsor. Upon receipt of the foregoing certifications, the Certificate
Registrar shall, subject to Section 5.2(e) and Section 5.3(a), reflect all or any such portion of the RR Interest
in the name of the prospective transferee.

 

(j)          
Other Exchanges. In the event that a Global 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 clauses (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

 

    -155-

     

    

 

Global Certificate to U.S. persons (as defined in Regulation S)
shall be limited to transfers made pursuant to the provisions of clause (e) above.

 

(l)          
If 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 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, Rule 144 or Regulation S
under the Act or, with respect to Non-Book Entry Certificates, that such Certificates are not “restricted” within the
meaning of Rule 144 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)         
None of the Class R Certificate, the Class E Certificates, the Class V1-E Certificates or the Class V2 Certificates may
be purchased by or transferred to any prospective purchaser or transferee that is or will be an employee benefit plan or other
plan subject to the fiduciary responsibility provisions of ERISA or Section 4975 of the Code or a governmental plan (as defined
in Section 3(32) of ERISA) or other plan that is subject to any federal, state or local law that is, to a material extent, similar
to the foregoing provisions of ERISA or the Code (“Similar Law”) (each, a “Plan”), or any
person acting on behalf of any such Plan or using the assets of a Plan to purchase the Class R Certificate, the Class E Certificates,
the Class V1-E Certificates or the Class V2 Certificates, other than, in the case of the Class E Certificates, the Class V1-E Certificates
and the Class V2 Certificates, an insurance company using assets of its general account under circumstances whereby such purchase
and the subsequent holding of the Class E Certificates , the Class V1-E Certificates or the Class V2 Certificates by such insurance
company would be exempt from the prohibited transaction provisions of Sections 406 and 407 of ERISA and Section 4975 of the Code
under Sections I and III of Prohibited Transaction Class Exemption 95-60, or a substantially similar exemption under Similar Law.
Each prospective transferee of the Class R Certificate, the Class E Certificates, the Class V1-E Certificates or the Class V2 Certificates
shall deliver to the transferor, the Certificate Registrar and the Certificate Administrator a representation letter, substantially
in the form of Exhibit M-3, stating that the prospective transferee is not a person described in the first sentence of this
paragraph. No Class A, Class X-A, Class X-B, Class B, Class C, Class D, Class V1-A, Class V1-XB, Class V1-C, or Class V1-D Certificates
may be purchased by or transferred to any prospective purchaser or transferee that is or will be a Plan, or any person acting on
behalf of any such plan or using the assets of a Plan to purchase such Certificate, unless (A) the purchaser is an accredited investor
(as defined in Rule 501(a)(1) under the Act) and (B) the acquisition, holding and disposition of such Certificate by the purchaser
will not constitute or otherwise result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code (or
a similar non-exempt violation of Similar Law). 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.

(o)         
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
of a Residual Ownership Interest 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 M-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. Person, (5) the proposed transferee will not transfer the Residual Ownership Interest
to any Person that does not provide a Transferee Affidavit or as to which the proposed transferee has actual knowledge that such
Person is not a Permitted Transferee or is acting as an agent (including a broker, nominee or other middleman) for a Person that
is not a Permitted Transferee, and (6) the proposed transferee expressly agrees to be bound by and to abide by the provisions
of this Section 5.3(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 M-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 the Transferee Affidavit are false.

 

    -157-

     

    

 

(iii)          
Notwithstanding the delivery of a Transferee Affidavit by a proposed transferee under clause (ii) above, if
a Responsible Officer of the Certificate Registrar has actual knowledge that the proposed transferee is not a Permitted Transferee,
no transfer to such proposed transferee shall be effected and such proposed transfer shall not be registered on the Certificate
Register; provided, however, that the Certificate Registrar shall not be required to conduct any independent investigation
to determine whether a proposed transferee is a Permitted Transferee. Upon notice to the Certificate Registrar that there has occurred
a transfer to any Person that is a Disqualified Organization or an agent thereof (including a broker, nominee or middleman) in
contravention of the foregoing restrictions, and in any event not later than 60 days after a request for information from the transferor
of such Residual Ownership Interest or such agent, the Certificate Registrar and the Certificate Administrator agree to furnish
to the IRS 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.

 

(iv)        
The Class R Certificates may only be issued as Definitive Certificates, and transferred to and owned by QIBs.

 

5.4.              
Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate
and (b) there is delivered to the Certificate Registrar such security or indemnity as may be required by it to save it harmless,
then, in the absence of actual notice to the Certificate Registrar that such Certificate has been acquired by a bona fide purchaser,
the Certificate Registrar shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed,
lost or stolen Certificate, a new Certificate of like tenor and interest in the Trust Fund. In connection with the issuance of
any new Certificate under this Section 5.4, 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
issued pursuant to this Section 5.4 shall constitute complete and indefeasible evidence of ownership in the Trust Fund,
as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

 

5.5.              
Persons Deemed Owners. The Servicer, the Special Servicer, the Certificate Administrator, the Trustee and the Certificate
Registrar, and any agent of any of them, 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 this Agreement and for all other purposes whatsoever, and
neither the Servicer, the Special Servicer, the Certificate Administrator, the Trustee, the Certificate Registrar, nor any agent
of any of them shall be affected by any notice to the contrary; provided, however, that to the extent that a party
to this Agreement responsible for distributing any report, statement or other information required to be

 

    -158-

     

    

 

distributed to Certificateholders
has been provided an Investor Certification, such party to this Agreement shall distribute such report, statement or other information
to such beneficial owner (or prospective transferee).

 

5.6.              
Access to List of Certificateholders’ Names and Addresses; Special Notices. The Certificate Registrar shall
maintain in as current form as is reasonably practicable the most recent list available to it of the names and addresses of the
Certificateholders. If any Certificateholder that has provided an Investor Certification (a) requests in writing from the
Certificate Registrar a list of the names and addresses of Certificateholders, (b) states that such Certificateholder desires
to communicate with other Certificateholders with respect to its rights under this Agreement or under the Certificates and (c) provides
a copy of the communication which such Certificateholder proposes to transmit, then the Certificate Registrar shall, within 10
Business Days after the receipt of such request, afford such Certificateholder access during normal business hours to a current
list of the Certificateholders. Every Certificateholder, by receiving and holding a Certificate, agrees that the Certificate Registrar
and the Certificate Administrator shall not be held accountable by reason of the disclosure of any such information as to the list
of the Certificateholders hereunder, regardless of the source from which such information was derived. The Servicer, the Special
Servicer and the Depositor shall be entitled to a list of the names and addresses of Certificateholders from time to time upon
request therefor.

 

Upon the written request of any
Certificateholder or Beneficial Owner that (a) has provided an Investor Certification, (b) states that such Certificateholder
or Beneficial Owner desires the Certificate Administrator to transmit a notice to all Certificateholders or Beneficial Owner stating
that such Certificateholder wishes to be contacted by other Certificateholders or Beneficial Owners, setting forth the relevant
contact information and briefly stating the reason for the requested contact (a “Special Notice”) and (c) provides
a copy of the Special Notice which such Certificateholder or Beneficial Owner proposes to transmit, the Certificate Administrator
shall post such Special Notice to the Certificate Administrator’s Website pursuant to Section 8.14(b) and shall
mail such Special Notice to all Certificateholders at their respective addresses appearing on the Certificate Register. The costs
and expenses of the Certificate Administrator associated with delivering any such Special Notice shall be borne by the party requesting
such Special Notice. Every Certificateholder and Beneficial Owner, by receiving and holding or beneficially owning a Certificate,
agrees that neither the Certificate Administrator nor the Certificate Registrar shall be held accountable by reason of the disclosure
of any such Special Notice to Certificateholders, regardless of the information set forth in such Special Notice.

 

5.7.              
Maintenance of Office or Agency. The Certificate Registrar shall maintain or cause to be maintained an office or
offices or agency or agencies where Certificates may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Certificate Registrar in respect of the Certificates and this Agreement may be served. The Certificate
Registrar initially designates its office at Wells Fargo Bank, National Association, 600 South 4th Street, 7th
Floor, MAC N9300-070, Minneapolis, Minnesota 55479 as its office for such purposes. The Certificate Registrar shall give prompt

(a)          
The Grantor Trust shall be maintained by the Certificate Administrator, on behalf of the Trustee, in part for the benefit
of the Holders of the Certificates (other than the Class R Certificates). The assets of the Grantor Trust held for the benefit
of the Holders of the Certificates (other than the Class R Certificates) shall consist of the Regular Interests. The Regular Interests
shall be held by the Certificate Administrator for the benefit of the Trustee. At all times, each Regular Certificate shall represent
beneficial ownership interests in the related Class Percentage Interest of the related Regular Interest, in each case, with the
corresponding alphabetical and numerical designation. At all times, the Class V1-A Certificates shall represent beneficial ownership
interests in the Class V1-A Percentage Interest of the Class A and Class X-A Regular Interests. At all times, the Class V1-XB Certificates

On the Closing Date, the Grantor Trust shall issue the several Classes of Certificates (other than the Class R Certificates).
Each Class of Certificates (other than the Class R Certificates) shall be initially issued (or, in the case of the Regular Certificates
and Certificates that initially evidence the RR Interest, deemed to be issued and simultaneously exchanged in accordance with Section
5.8(d)) on the Closing Date with the respective aggregate initial Certificate Balance or Notional Amount, as applicable, set
forth for such Class in the Introductory Statement.

 

(c)          
Following the Closing Date and subject to the conditions set forth in Section 5.8(d), if a Certificateholder holds
a uniform Tranche Percentage Interest in an Exchangeable Group of Certificates, then such Exchangeable Group of Certificates may
be exchanged on the books of the Depository for the same Tranche Percentage Interest in any other Exchangeable Group of Certificates
as the Certificates to be surrendered. The Certificate(s) identified in the table below under “Exchangeable Group 1”,
“Exchangeable Group 2” and “Exchangeable Group 3” are each an “Exchangeable Group” of
Certificates.

For the avoidance of doubt, by
way of example, the holder of a uniform Tranche Percentage Interest of each Class of Regular Certificates (collectively referred
to in the table above as “Exchangeable Group 1”) may exchange such Certificates for the same Tranche Percentage Interest
in either (i) the Class V1-A, Class V1-XB, Class V1-B, Class V1-C, Class V1-D and Class V1-E Certificates (collectively referred
to in the table above as “Exchangeable Group 2”) or (ii) the Class V2 Certificates (referred to in the table above
as “Exchangeable Group 3”).

 

(d)         
An exchange of an Exchangeable Group of Certificates may only occur if the Certificates being surrendered or received in
such exchange have denominations no smaller than the minimum Denominations set forth in Section 5.1(b). There shall be no
limitation on the number of exchanges of Exchangeable Groups of Certificates authorized pursuant to this Section 5.8. In
addition, the Depositor shall have the right to make or cause exchanges on the Closing Date and shall deliver instructions substantially
in the form of Exhibit R to the Certificate Administrator along with the original Certificate exchanged (unless such exchanged
Certificate was deemed issued).

 

(e)         
For any exchange other than any exchange effectuated on the Closing Date by the Depositor pursuant to Section 5.8(d),
at the request of the Holder of a uniform Tranche Percentage Interest of an Exchangeable Group of Certificates, and upon the surrender
of the Certificates evidencing such Tranche Percentage, the Certificate Administrator, on behalf of the Trustee, shall deliver
(by the means set forth in the penultimate sentence of Section 5.8(g)) the corresponding Exchangeable Group of Certificates
to which such Certificateholder is entitled as set forth in Section 5.8(c).

 

(f)          
In connection with any exchange of an Exchangeable Group of Certificates, (i) the Certificate Registrar shall reduce the
outstanding aggregate Certificate Balance or Notional Amount, as applicable, of the Class or Classes comprising the Exchangeable
Group of Certificates surrendered by the applicable Holder on the Certificate Register and shall increase the outstanding aggregate
Certificate Balance or Notional Amount, as applicable, of the related Class or Classes of the Exchangeable Group of Certificates
received by such Holder in such exchange on the Certificate Register, (ii) the Certificate Registrar shall reduce the initial Certificate
Balance or Notional Amount specified in the Introductory Statement to this Agreement, as applicable, of the Class or Classes comprising
the Exchangeable Group of Certificates surrendered by the applicable Holder on the Certificate Register and shall increase the
initial Certificate Balance or Notional Amount specified in the Introductory Statement to this Agreement, as applicable, of the
related Class or Classes of the Exchangeable Group of Certificates received by such Holder, and (iii) in the case of any related
Global Certificate, the

 

    -161-

     

    

 

Certificate Registrar or the Certificate Administrator, as applicable, shall approve the instructions at
the Depository and make appropriate notations on the Global Certificate for each related Class of Certificates to reflect such
reductions and increases. Any transfer of a Certificate evidencing the RR Interest to (i) a Plan subject to ERISA or Section 4975
of the Code relying on Prohibited Transaction Exemption 89-90 or (ii) an insurance company general account relying on Sections
I and III of PTCE 95-60 shall be effected through Natixis Securities Americas LLC or Credit Suisse Securities (USA) LLC.

 

(g)         
For all exchanges other than any exchange effectuated by the Depositor pursuant to Section 5.8(d), in order to effect
an exchange of an Exchangeable Group of Certificates, the Certificateholder shall notify the Certificate Administrator in writing
or by e-mail at cts.cmbs.bond.admin@wellsfargo.com (with a subject line referencing “NCMS 2017-75B” and setting
forth the proposed Exchange Date) no later than three (3) Business Days before the proposed exchange date (the “Exchange
Date”). The Exchange Date may be any Business Day other than the first or last Business Day of the month. An exchange
notice must (i) be set forth on the applicable Certificateholder’s letterhead, (ii) carry a medallion stamp guarantee and
(iii) set forth the following information: the CUSIP Number of each Certificate to be exchanged and each Certificate to be received;
the original and outstanding Certificate Balance or Notional Amount, as applicable, of the Certificates to be exchanged and the
original and outstanding Certificate Balance or Notional Amount, as applicable, of the Certificates to be received; the Certificateholder’s
Depository participant number, if applicable; and the proposed Exchange Date. The Certificateholder and the Certificate Registrar
shall utilize the “deposit and withdrawal system” at the Depository to effect the exchange of the applicable Certificates
that are Global Certificates. A notice shall become irrevocable on the second (2nd) Business Day before the proposed Exchange Date.
Global Certificates shall be exchangeable on the books of the Depository for the corresponding Global Certificates on and after
the Closing Date, by notice to the Certificate Administrator substantially in the form of Exhibit R.

 

(h)          
The Certificate Administrator shall make the first distribution on a Certificate received by a Certificateholder in any
exchange on the Distribution Date in the month following the month of exchange to the Certificateholder of record as of the applicable
Record Date for such Certificate and Distribution Date. If an Exchange Date occurs in any month before the Distribution Date in
such month, then any distributions to be made on such Distribution Date on any Certificates surrendered in the exchange shall be
so made to the Certificateholder of record as of the applicable Record Date for such Certificates and such Distribution Date. Neither
the Certificate Administrator nor the Depositor shall have any obligation to ensure the availability of the applicable Certificates
in the market to accomplish any exchange.

(c)          
If a Servicer Termination Event or Special Servicer Termination Event shall occur then, and in each and every such case,

Trustee may, or (ii) upon the written direction of Holders of Certificates having at least 25% of the Voting Rights (taking
into account the application of the Appraisal Reduction Amount to notionally reduce the Certificate Balances of the Certificates)
of the Certificates, the Trustee shall terminate all of the rights and obligations of the Servicer or the Special Servicer, as
applicable, under this Agreement, other than rights and obligations accrued prior to such termination, and in and to the Whole
Loan and the proceeds thereof by notice in writing to the Servicer or the Special Servicer, as applicable. Upon any termination
of the Servicer or the Special Servicer, as applicable, and appointment of a successor to the Servicer or the Special Servicer,

and the Companion Loan Holders. During any Subordinate Control Period, the Directing Holder shall have the right to select the
successor special servicer following any Special Servicer Termination Event. Also, notwithstanding the foregoing, if a Servicer
Termination Event on the part of the Servicer or the Special Servicer affects only a Companion Loan, any holder thereof or the
rating on a class of Senior Companion Loan Securities, then the Servicer or Special Servicer, as applicable may not be terminated
at the direction of the holders of any Certificates or any Companion Loan Holder (acting in such capacities); provided that,
the Companion Loan Holders shall be entitled to direct that the Trustee direct the Servicer to appoint a sub-servicer (or if the

 

    -169-

     

    

 

Whole Loan is currently being sub-serviced, then the Trustee will direct the Servicer to replace such sub-servicer with a new sub-servicer
but only if such original sub-servicer is in default (beyond any applicable cure periods) under the related sub-servicing agreement,
and the Servicer shall be permitted to terminate the sub-servicing agreement due to such default) that will be responsible for
servicing the Whole Loan.

 

(d)         
During any Subordinate Control Period, the Directing Holder shall have the right to direct the Trustee to terminate the
Special Servicer (subject to such terminated Special Servicer’s rights to indemnification, payment of outstanding fees, and
other rights set forth in this Agreement which survive termination) at any time, with or without cause, and the Directing Holder
shall have the right to, and shall, appoint a successor special servicer who shall execute and deliver to the other parties hereto
an agreement, in form and substance reasonably satisfactory to the Trustee, whereby the successor Special Servicer agrees to assume
and perform punctually the duties of the Special Servicer specified in this Agreement; provided that the Trustee shall have
obtained a Rating Agency Confirmation from each Rating Agency and each rating agency relating to the Senior Companion Loan Securities
prior to the termination of the Special Servicer. The Special Servicer shall not be terminated pursuant to this paragraph until
a successor special servicer shall have been appointed. The Directing Holder shall pay any costs and expenses incurred by the Trustee
or the Trust in connection with the removal and appointment of a Special Servicer pursuant to this paragraph (unless such removal
is based on any of the events or circumstances set forth in Section 7.1(a)). Notwithstanding anything to the contrary in
this Agreement, no successor special servicer appointed by the Directing Holder pursuant to Section 6.4, Section 7.1(c)
or this Section 7.1(d) or otherwise pursuant to this Agreement shall be required to meet any independent net worth requirements;
provided, however, that notwithstanding the foregoing, any successor special servicer shall satisfy any Rating Agency conditions
set forth in the Rating Agency Confirmation delivered by such Rating Agency with respect to such successor special servicer.

 

(e)         
After the termination of a Subordinate Control Period, upon (i) the written direction of holders of Sequential Pay
Certificates evidencing not less than 25% of the Voting Rights (taking into account the application of any Appraisal Reduction
Amounts to notionally reduce the Certificate Balances of the Certificates) of the Sequential Pay Certificates requesting a vote
to replace the Special Servicer with a new special servicer designated in such written direction, (ii) payment by such holders
to the Certificate Administrator of the reasonable fees and expenses (including any legal fees and expenses and any Rating Agency
fees and expenses) to be incurred by the Certificate Administrator in connection with administering such vote and (iii) delivery
by such holders to the Certificate Administrator of Rating Agency Confirmations from each Rating Agency and each rating agency
relating to the Senior Companion Loan Securities with respect to the appointment of such new special servicer (which Rating Agency
Confirmation shall be obtained at the expense of such holders), the Certificate Administrator shall promptly post written notice
of the same to the Certificate Administrator’s Website pursuant to Section 8.14(b), provide written notice to
all Certificateholders of such request by mail, and shall conduct the solicitation of votes of all Certificates in such regard.
If 66 2/3% of the aggregate Voting Rights have been exercised by the related Certificateholders, then, upon the written direction
of holders of Certificates evidencing at least 75% of the aggregate Voting Rights (taking into account the application of any Appraisal
Reduction Amounts to notionally reduce the Certificate Balances of the Certificates) of all Certificates whose holders exercise

 

    -170-

     

    

 

their right to vote (which direction must be received by the Certificate Administrator within 180 days of the request for a vote),
the Certificate Administrator shall notify the Trustee and the Trustee shall terminate all of the rights and obligations of the
Special Servicer under this Agreement and appoint the successor Special Servicer designated by such Certificateholders; provided
such successor Special Servicer is a Qualified Replacement Special Servicer and such successor Special Servicer is not also the
current special servicer of any Mezzanine Loan, and subject to the replaced Special Servicer’s indemnification, payment of
outstanding fees and other rights set forth in this Agreement which survive termination; provided further, such successor
Special Servicer certifies in writing that it satisfies all related qualifications set forth in the Co-Lender Agreement; provided
further that if such written direction is not provided within 180 days of the initial request for a vote to terminate and replace
the Special Servicer, then such written direction shall have no force and effect. The provisions set forth in the foregoing sentences
of this paragraph shall be binding upon and inure to the benefit of solely the Certificateholders and the Trustee as between each
other. The Special Servicer shall not have any cause of action based upon or arising from any breach or alleged breach of such
provisions. As between the Special Servicer, on the one hand, and the Certificateholders, on the other, the Certificateholders
shall be entitled in their sole discretion to vote for the termination or not vote for the termination of the Special Servicer.
The Holders of the Certificates that initiated the vote to replace the Special Servicer shall pay the costs and expenses incurred
in connection with the removal and replacement of the Special Servicer pursuant to this paragraph. The Certificate Administrator
shall include on each Distribution Date Statement a statement that each Certificateholder may access such notices on the Certificate
Administrator’s Website and that each Certificateholder may register to receive e-mail notifications when such notices are
posted thereon.

 

(f)          
In the event that the Servicer or Special Servicer is terminated pursuant to this Section 7.1, the Trustee (the
“Terminating Party”) shall, by notice in writing to the Servicer or Special Servicer, as the case may be (the
“Terminated Party”) (with a copy to the Borrower), terminate all of its rights and obligations under this Agreement
and in and to the Whole Loan and the proceeds thereof, other than any rights the Terminated Party may have hereunder as a Certificateholder
and any rights or obligations that accrued prior to the date of such termination (including the right to receive all amounts accrued
or owing to it under this Agreement with respect to periods prior to the date of such termination and the right to the benefits
of Section 6.3 notwithstanding any such termination). On or after the receipt by the Terminated Party of such written
notice, subject to the foregoing, all of its authority and power under this Agreement, whether with respect to the Certificates
(except that the Terminated Party shall retain its rights as a Certificateholder in the event and to the extent that it is a Certificateholder)
or the Whole Loan or otherwise, shall pass to and be vested in the Terminating Party pursuant to and under this Section (absent
the appointment of a successor, and such successor’s assumption of obligations hereunder, including, without limitation,
by the Directing Holder during any Subordinate Control Period) and, without limitation, the Terminating Party is hereby authorized
and empowered to execute and deliver, on behalf of and at the expense of the Terminated 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 Whole Loan and
related documents, or otherwise. The Servicer and the Special Servicer, as applicable, each agrees that, in the event it is terminated
pursuant to this Section 7.1, or resigns under Section 6.4(b), to promptly (and in

 

    -171-

     

    

 

any event no later than
ten Business Days subsequent to such notice) provide, at its own expense, the Terminating Party (which term shall include for the
purposes of the remainder of this Section 7.1(f), the Trustee (or a successor Servicer or Special Servicer) in connection
with a resignation of the Servicer or the Special Servicer under Section 6.4(b)) with all documents and records requested
by the Terminating Party to enable the Terminating Party to assume its functions hereunder, and to cooperate with the Terminating
Party and the successor to its responsibilities hereunder in effecting the termination of its responsibilities and rights hereunder,
including, without limitation, the transfer to the successor Servicer or Special Servicer, as applicable, or the Terminating Party,
as applicable, for administration by it of all cash amounts which shall at the time be or should have been credited by the Terminated
Party (which term shall include, for the purposes of the remainder of this Section 7.1(f), the resigning party in connection
with a resignation of the Servicer or the Special Servicer under Section 6.4(b)) to the Collection Account, the Companion
Loan Account, any Foreclosed Property Account or shall thereafter be received with respect to the Whole Loan, and shall promptly
provide the Terminating Party or such successor Servicer or Special Servicer, as applicable (which may include the Trustee), as
applicable, all documents and records reasonably requested by it, such documents and records to be provided in such form as the
Terminating Party or such successor Servicer or the Special Servicer, as applicable, shall reasonably request (including electromagnetic
form), to enable it to assume the function of the Servicer or Special Servicer, as applicable, hereunder. All reasonable costs
and expenses of the Terminating Party or the successor Servicer or Special Servicer, as applicable, incurred in connection with
transferring the Mortgage File to the Terminating Party or to the successor Servicer or Special Servicer, as applicable, and amending
this Agreement to reflect such succession pursuant to this Section 7.1 shall be paid by the Terminated Party upon presentation
of reasonable documentation of such costs and expenses. If the Terminated Party has not reimbursed the Terminating Party or such
successor Servicer or Special Servicer, as applicable, for such expenses within 90 days after the presentation of reasonable documentation,
such expense shall be reimbursed by the Trust pursuant to Section 3.4(c); provided that the Terminated Party
shall not thereby be relieved of its liability for such expenses.

 

(g)         
In no event shall the Trustee be deemed to have knowledge of or be aware of any Servicer Termination Event or Special Servicer
Termination Event until a Responsible Officer of the Trustee has received written notice thereof or has actual knowledge thereof.

 

7.2.              
Trustee to Act; Appointment of Successor. (a) On and after the time the Servicer or Special Servicer, as the case
may be, receives a notice of termination pursuant to Section 7.1, or resigns pursuant to Section 6.4(b),
the Terminating Party (which term shall include, for the purposes of the remainder of this Section 7.2, the Trustee
(or a successor Servicer or Special Servicer including a successor appointed under Section 6.4(a)) in connection with
a resignation of the Servicer or the Special Servicer under Section 6.4(b)) shall, unless prohibited by law, be the
successor to the Terminated Party (which term shall include, for the purposes of the remainder of this Section 7.2,
the resigning party in connection with a resignation of the Servicer of the Special Servicer under Section 6.4(b))
in all respects under this Agreement and the transactions set forth or provided for herein and, except as provided herein, shall
be subject to all the responsibilities, duties, limitations on liability and liabilities relating thereto and arising thereafter
placed on the Terminated Party by the terms and provisions hereof; provided, however, that (i) neither the Trustee
nor the Terminating Party (or any successor

 

    -172-

     

    

 

Servicer or Special Servicer, as the case may be) shall have responsibilities, duties,
liabilities or obligations with respect to any act or omission of the Terminated Party and (ii) any failure to perform, or
delay in performing, such duties or responsibilities caused by the Terminated Party’s failure to provide, or delay in providing,
records, tapes, disks, information or monies or failure to cooperate as required by this Agreement shall not be considered a default
by the Terminating Party or such successor hereunder. The Trustee, as successor Servicer, and any other successor Servicer or Special
Servicer, as the case may be, shall be indemnified to the full extent provided to the Trustee under this Agreement. The appointment
of a successor Servicer or Special Servicer, as the case may be, shall not affect any liability of the Terminated Party that may
have arisen prior to its termination as such. The Terminating Party shall not be liable for any of the representations and warranties
of the Terminated Party herein or in any related document or agreement, for any acts or omissions of the Terminated Party or for
any losses incurred in respect of any Permitted Investment by the Terminated Party nor shall the Terminating Party or any successor
Servicer or Special Servicer be required to purchase the Trust Loan or a Companion Loan hereunder. As compensation therefor, the
Terminating Party as successor Servicer or Special Servicer, as the case may be, shall be entitled to all compensation with respect
to the Trust Loan or a Companion Loan to which the Terminated Party would have been entitled that accrues after the date of the
Terminating Party’s succession to which the Terminated Party would have been entitled if it had continued to act hereunder
and, in the case of a successor Special Servicer, the Special Servicing Fee. Notwithstanding the above, the Trustee may, if it
shall be unwilling to so act, or shall, if it is unable to so act, or if the Holders of Certificates having greater than 25% of
the aggregate Voting Rights of all then outstanding Certificates so request in writing to the Trustee, or the Trustee is not approved
by the Rating Agencies and each rating agency relating to the Senior Companion Loan Securities as a Servicer or Special Servicer,
as the case may be, as evidenced by a Rating Agency Confirmation or if a Rating Agency Confirmation is not obtained, promptly appoint,
or petition a court of competent jurisdiction to appoint, any established loan servicing institution reasonably satisfactory to
the Trustee the appointment for which a Rating Agency Confirmation is obtained, as the successor to the Servicer or Special Servicer,
as applicable, hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer or
Special Servicer, as applicable, hereunder. No appointment of a successor to a Terminated Party hereunder shall be effective until
the assumption by such successor of all the Terminated Party’s responsibilities, duties and liabilities hereunder. Pending
appointment of a successor to a Terminated Party hereunder, unless the Trustee shall be prohibited by law from so acting, the Trustee
shall act in the applicable capacity as herein above provided. Any appointment or succession by the Trustee to the rights and obligations
of the Special Servicer hereunder shall be subject to the Directing Holder’s right to replace the Special Servicer during
any Subordinate Control Period. In connection with such appointment and assumption described herein, the Trustee may make such
arrangements for the compensation of such successor out of payments on the Whole Loan as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of that permitted the Terminated Party hereunder, except that if no
successor to the Terminated Party can be obtained to perform the obligations of such Terminated Party hereunder, additional amounts
shall be paid to such successor and such amounts in excess of that permitted the Terminated Party shall be paid pursuant to Section 3.4(c).
The Depositor, the Trustee, the Certificate Administrator, the Servicer (as applicable), the Special Servicer (as applicable) and
such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

 

    -173-

     

    

 

(b)          Notwithstanding
Section 7.1(b) of this Agreement, if a Servicer receives a notice of termination solely due to a Servicer Termination Event
or Special Servicer Termination Event, as applicable, under Section 7.1(a)(vii) or (viii) and the terminated Servicer
provides the Trustee with the appropriate “request for proposal” materials within five (5) Business Days after such
termination, then such Servicer shall continue to serve as Servicer, if requested to do so by the Trustee, and the Trustee shall
promptly thereafter (using such “request for proposal” materials provided by the terminated Servicer) solicit good
faith bids for the rights to master service the Whole Loan from at least three (3) Persons qualified to act as successor servicer
hereunder in accordance with Section 6.2 and Section 7.2 for which the Trustee has received Rating Agency Confirmation
(any such Person so qualified, a “Qualified Bidder”) or, if three (3) Qualified Bidders cannot be located, then
from as many Persons as the Trustee can determine are Qualified Bidders; provided, however, that (i) at the Trustee’s
request, the terminated Servicer shall supply the Trustee with the names of Persons from whom to solicit such bids; and (ii) the
Trustee shall not be responsible if less than three (3) or no Qualified Bidders submit bids for the right to master service the
Whole Loan under this Agreement. The bid proposal shall require any Successful Bidder (as defined below), as a condition of such
bid, to enter into this Agreement as successor Servicer with respect to the Whole Loan, and to agree to be bound by the terms hereof,
within forty-five (45) days after the receipt by the terminated Servicer of a notice of termination. The Trustee shall solicit
bids (i) on the basis of such successor servicer entering into a sub-servicing agreement with the terminated Servicer to service
the Whole Loan at a sub-servicing fee rate per annum equal to the Servicing Fee minus the Retained Fee Rate (each, a “Servicing-Retained
Bid”) and (ii) on the basis of having no obligation to enter into a sub-servicing agreement with the terminated Servicer
(each, a “Servicing-Released Bid”). The Trustee shall select the Qualified Bidder with the highest cash Servicing-Retained
Bid (or, if none, the highest cash Servicing Released Bid) (the “Successful Bidder”) to act as successor servicer
hereunder. The Successful Bidder shall enter into this Agreement as successor servicer pursuant to the terms hereof (and, if the
successful bid was a Servicing-Retained Bid, to enter into a sub-servicing agreement with the terminated Servicer as contemplated
above), no later than forty-five (45) days after the termination of the terminated Servicer. Upon the assignment and acceptance
of the servicing rights hereunder to and by the Successful Bidder, and upon payment of the proceeds by the Successful Bidder to
the Certificate Administrator, the Certificate Administrator shall remit or cause to be remitted to the terminated Servicer the
amount of such cash bid received from the Successful Bidder (net of “out of pocket” expenses incurred in connection
with obtaining such bid and transferring servicing).

 

If the Trustee or an Affiliate
acts pursuant to this Section 7.2 as successor to the resigning or terminated Servicer, it may reduce such terminated Servicer’s
Retained Fee Rate and/or Excess Servicing Fee to the extent that its or such Affiliate’s compensation as successor Servicer
would otherwise be below market rate servicing compensation. If the Trustee elects to appoint a successor to the resigning or terminated
Servicer other than itself or an Affiliate pursuant to this Section 7.2, it may reduce the Retained Fee Rate and/or Excess Servicing
Fee to the extent reasonably necessary (in the sole discretion of the Trustee) for the Trustee to appoint a qualified successor
Servicer that meets the requirements of this Section 7.2.

 

7.3.              
[Reserved.]

 

    -174-

     

    

 

7.4.          Other Remedies of Trustee. During the continuance of any Servicer Termination Event or Special Servicer Termination
Event, as the case may be, or so long as such Servicer Termination Event or Special Servicer Termination Event shall not have been
remedied, the Trustee, in addition to the rights specified in Section 7.1, shall have the right, in its own name as
trustee of an express trust, to take all actions now or hereafter existing at law, in equity or by statute to enforce its rights
and remedies and to protect the interests, and enforce the rights and remedies, of the Certificateholders and the Companion Loan
Holders (including the institution and prosecution of all judicial, administrative and other proceedings and the filing of proofs
of claim and debt in connection therewith). In such event, the legal fees, expenses and costs of such action and any liability
resulting therefrom shall be expenses, costs and liabilities of the Trust, and the Trustee shall be entitled to be reimbursed therefor
pursuant to Section 3.4(c) from the Collection Account (and such amounts shall be allocated in accordance with the
expense allocation provisions of the Co-Lender Agreement). Except as otherwise expressly provided in this Agreement, no remedy
provided for by this Agreement shall be exclusive of any other remedy, and each and every remedy shall be cumulative and in addition
to any other remedy and no delay or omission to exercise any right or remedy shall impair any such right or remedy or shall be
deemed to be a waiver of any Servicer Termination Event or Special Servicer Termination Event.

 

7.5.          Waiver of Past Servicer Termination Events and Special Servicer Termination Events. The Holders of Certificates evidencing
not less than 66 2/3% of the aggregate Voting Rights of all then outstanding Certificates may, on behalf of all Certificateholders
and upon adequate indemnification of the Trustee by the requesting Holders of Certificates, waive any default by the Servicer or
the Special Servicer in the performance of its obligations hereunder and its consequences, except a default in making any required
deposits (including Monthly Payment Advances) to or payments from the Collection Account, the Distribution Account or any Foreclosed
Property Account or in remitting payments as received, in each case in accordance with this Agreement. Upon any such waiver of
a past default, such default shall cease to exist, and the related Servicer Termination Event or Special Servicer Termination Event
arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any
subsequent or other default or impair any right related thereto.

 

7.6.          Trustee as Maker of Advances. In the event that the Servicer fails to fulfill its obligations hereunder to make any
Advances, the Trustee shall perform such obligations (w) within five Business Days (or such shorter period (but not less than
one Business Day) as may be required, if applicable, to avoid any lapse in insurance coverage required under the Loan Documents
or this Agreement with respect to the Property or to avoid any foreclosure or similar action with respect to the Property by reason
of failure to pay real estate taxes, assessments, ground or leasehold rents or governmental charges) of a Responsible Officer of
the Trustee obtaining knowledge of such failure by the Servicer or the Special Servicer with respect to any Advances (other than
any Monthly Payment Advances on the Trust Loan) and (x) by 12:00 noon New York time on the related Distribution Date with
respect to Monthly Payment Advances on the Trust Loan. If the Certificate Administrator has not received any required Monthly Payment
Advance on the Trust Loan from the Servicer by 11:00 a.m. on the related Distribution Date, the Certificate Administrator shall
provide notice to that effect to the Trustee, and if the required Monthly Payment Advance on the Trust Loan is still not received
by the

 

    -175-

     

    

 

Certificate Administrator by 11:45 a.m. on the related Distribution Date, the Certificate Administrator shall again provide
notice to that effect to the Trustee, who shall then perform the obligations set forth in the preceding sentence. With respect
to any such Advance made by the Trustee, the Trustee shall succeed to all of the Servicer’s and/or the Special Servicer’s
rights, as applicable, with respect to Advances hereunder, including, without limitation, the rights of reimbursement and interest
on each Advance at the Advance Rate, and rights to determine that a proposed Advance is a Nonrecoverable Advance (without regard
to any impairment of any such rights of reimbursement caused by such Servicer’s and/or the Special Servicer’s default
in its obligations hereunder and further subject to the Trustee’s standard of good faith judgment); provided, however,
that if Advances made by the Trustee, the Servicer and/or the Special 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 (in that order) until such Advances shall have been repaid in full,
together with all interest accrued thereon, prior to reimbursement of the Servicer and/or the Special Servicer, as applicable,
for such Advances and interest accrued thereon. The Trustee shall be entitled to conclusively rely on any notice given by the Servicer
and/or the Special Servicer, as applicable, with respect to a Nonrecoverable Advance hereunder. The Servicer or the Trustee, as
applicable, shall not be responsible for advancing Monthly Payment Advances or Administrative Advances with respect to the Companion
Loans.

 

8.          THE TRUSTEE AND Certificate Administrator

 

8.1.          Duties of the Trustee and the Certificate Administrator. (a)  Each of the Trustee and the Certificate Administrator,
prior to the occurrence of a Servicer Termination Event or Special Servicer Termination Event, as the case may be, and after the
curing or waiver of any Servicer Termination Event or Special Servicer Termination Event that may have occurred, undertakes with
respect to the Trust Fund to perform such duties and only such duties as are specifically set forth in this Agreement. Neither
the Depositor nor the Servicer nor the Special Servicer shall be obligated to monitor or supervise the performance by the Trustee
or the Certificate Administrator of its duties hereunder. In case a Servicer Termination Event or Special Servicer Termination
Event has occurred (which has not been cured or waived), the Trustee, subject to the provisions of Sections 7.2 and
7.4, shall exercise such of the rights and powers vested in it by this Agreement, and shall use the same degree of care
and skill in their exercise, as a prudent institution would exercise or use under the circumstances in the conduct of such institution’s
own affairs. Any permissive right of the Trustee or the Certificate Administrator set forth in this Agreement shall not be construed
as a duty. The Trustee (or the Servicer or the Special Servicer on its behalf) shall have the power to exercise all the rights
of a holder of the Whole Loan on behalf of the Certificateholders and the Companion Loan Holders, subject to the terms of the Loan
Documents and the Co-Lender Agreement; provided, however, that the Lender’s obligations under the Loan Documents
shall be exercised by the Servicer or Special Servicer, as the case may be, pursuant to this Agreement.

 

(b)           Subject to Sections 8.2(a) and 8.3, each of the Trustee and the Certificate Administrator, upon receipt
of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee
or the Certificate Administrator that are specifically required to be furnished to it pursuant to any provision of this Agreement,
shall examine, or cause to be examined, such instruments to determine whether they conform to

 

    -176-

     

    

 

the requirements of this Agreement
to the extent specifically set forth herein. If any such instrument is found on its face not to conform to the requirements of
this Agreement in a material manner, the Trustee or the Certificate Administrator, as applicable, may take such action as it deems
appropriate to have the instrument corrected, and if the instrument is not corrected to the Trustee’s or the Certificate
Administrator’s reasonable satisfaction, the Trustee or the Certificate Administrator shall provide notice thereof to the
Certificateholders. Neither the Trustee nor the Certificate Administrator shall be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other instrument furnished by the Depositor, the Servicer,
or the Special Servicer and accepted by the Trustee or the Certificate Administrator, as the case may be, in good faith, pursuant
to this Agreement.

 

(c)            Subject to Section 8.3, no provision of this Agreement shall be construed to relieve the Trustee or the Certificate
Administrator from liability for its own negligent action, its own negligent failure to act, its failure to perform its obligations
in compliance with this Agreement, its own willful misconduct or bad faith; provided, however, that:

 

(i)             no implied covenants or obligations shall be read into this Agreement against the Trustee or the Certificate Administrator
and each of the Trustee and the Certificate Administrator may conclusively rely, as to the truth of the statements and the correctness
of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and/or the Certificate Administrator
(including those provided pursuant to Section 10.1) and conforming to the requirements of this Agreement which it
reasonably believes in good faith to be genuine and to have been duly executed by the proper authorities respecting any matters
arising hereunder;

 

(ii)            the Trustee and the Certificate Administrator shall not be liable for an error of judgment made in good faith by a Responsible
Officer of the Trustee or the Certificate Administrator, unless it shall be proved that the Trustee or the Certificate Administrator
or such Responsible Officer, as applicable, was negligent in ascertaining the pertinent facts;

 

(iii)           the Trustee and the Certificate Administrator shall not be liable with respect to any action taken, suffered or omitted
to be taken by it in good faith in accordance with this Agreement or at the direction of Holders of Certificates evidencing, in
the aggregate, not less than 25% of the 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;

 

(iv)          the Trustee and the Certificate Administrator shall not be charged with knowledge of any failure by the Servicer or the
Special Servicer to comply with any of their respective obligations referred to in Section 7.1 or any other act or
circumstance upon the occurrence of which the Trustee or the Certificate Administrator, as applicable, may be required to take
action unless a Responsible Officer of the Trustee or the Certificate Administrator, as applicable, obtains actual knowledge of
such failure, act or circumstance or the Trustee or the Certificate Administrator, as applicable, receives written notice of such
failure from the Servicer, the Special Servicer, the Depositor, the

 

    -177-

     

    

 

Borrower or Holders of the Certificates evidencing, in the
aggregate, not less than 25% of the Voting Rights of the Certificates;

 

(v)           subject
to the other provisions of this Agreement and without limiting the generality of Sections 8.1 and 8.2, neither
the Trustee nor the Certificate Administrator shall have any duty except in the case of the Trustee, acting in its capacity as
a successor Servicer or successor Special Servicer (A) to record, file or deposit this Agreement or any agreement referred
to herein or any financing statement or continuation statement evidencing a security interest, or to maintain of any such recording
or filing or depositing or any re-recording, refiling or redepositing thereof, (B) to maintain any insurance, and (C) to
confirm or verify the contents of any reports or certificates of the Servicer or the Special Servicer delivered to the Trustee
or the Certificate Administrator pursuant to this Agreement reasonably believed by the Trustee or the Certificate Administrator
to be genuine and to have been signed or presented by the proper party or parties; and

 

(vi)          for
all purposes under this Agreement, the Trustee and the Certificate Administrator shall not be required to take any action with
respect to, or be deemed to have notice or knowledge of any Loan Event of Default, Servicer Termination Event or Special Servicer
Termination Event unless a Responsible Officer of the Trustee or the Certificate Administrator, as applicable, has actual knowledge
thereof or shall have received written notice thereof. In the absence of receipt of such notice and such actual knowledge otherwise
obtained, the Trustee and the Certificate Administrator may conclusively assume that there is no Loan Event of Default, Servicer
Termination Event or Special Servicer Termination Event.

 

(d)           None of the provisions contained in this Agreement shall in any event require the Trustee or the Certificate Administrator
to (i) expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers hereunder if there are reasonable grounds for believing that repayment
of such funds or adequate indemnity against such risk or liability is not reasonably assured to it, or (ii) exercise any of
its rights or powers or take any action if it determines such exercise or action is contrary to law, and none of the provisions
of this Agreement shall in any event require the Trustee or Certificate Administrator, as applicable, to perform, or be responsible
for the manner of performance of, any of the obligations of the Servicer or the Special Servicer under this Agreement, except with
respect to the Trustee, during such time, if any, as the Trustee shall be the successor to, and be vested with the rights, duties,
powers and privileges of, the Servicer or the Special Servicer in accordance with the terms of this Agreement. Notwithstanding
anything contained herein, neither the Trustee nor the Certificate Administrator shall be responsible or have liability in connection
with the duties assumed by the Authenticating Agent, and the Certificate Registrar hereunder, unless the Trustee or the Certificate
Administrator is acting in any such capacity hereunder; provided, further, that in any such capacity the Trustee
and the Certificate Administrator shall have all of the rights, protections and indemnities provided to it as Trustee and the Certificate

Matters Affecting the Trustee and the Certificate Administrator. (a)  Except as otherwise provided in Section 8.1:

 

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

 

(ii)           each of the Trustee and the Certificate Administrator may consult with any nationally recognized counsel, and the advice
of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken
or suffered or omitted by it hereunder in good faith and in accordance with such Opinion of Counsel;

 

(iii)           neither the Trustee nor the Certificate Administrator shall be under any obligation to exercise any of the trusts or powers
vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request,
order or direction of any of the Certificateholders, pursuant to the provisions of this Agreement, unless such Certificateholders
shall have offered to the Trustee or the Certificate Administrator security or indemnity reasonably satisfactory to it against
the costs, expenses and liabilities, including reasonable legal fees, which may be incurred therein or thereby; provided,
however, that nothing contained herein shall relieve the Trustee or the Certificate Administrator of the obligation, upon
the occurrence of a Servicer Termination Event or Special Servicer Termination Event, as the case may be (which has not been cured
or waived), to exercise such of the rights and powers vested in it by this Agreement, and with respect to the Trustee, to use
the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct
of such person’s own affairs;

 

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

 

(v)           prior to the occurrence of a Servicer Termination Event or Special Servicer Termination Event hereunder and after the curing
or waiver of such Servicer Termination Event or Special Servicer Termination Event that may have occurred, neither the Trustee
nor the Certificate Administrator shall be bound to ascertain or inquire as to the performance or observance of any of the terms,
conditions, covenants or agreements herein (except as specifically required by this Agreement) or 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 so to do by Holders of Certificates evidencing,
in the aggregate, not less than 25% of the Voting Rights of the outstanding Certificates; provided, however, that
if the payment within a reasonable time to the Trustee or the

 

    -179-

     

    

 

Certificate Administrator of the costs, expenses or liabilities
likely to be incurred by either party in the making of such investigation is, in the opinion of the Trustee or the Certificate
Administrator, 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, as applicable, may require indemnity satisfactory to it against
such costs, expenses or liabilities as a condition to taking any such action. The reasonable expense of every such investigation
shall be paid by the Trust pursuant to Section 3.4(c) in the event that such investigation relates to a Servicer Termination

requesting the investigation (and such expense shall be allocated in accordance with the allocation provisions of the Co-Lender
Agreement);

 

(vi)          each of the Trustee and the Certificate Administrator may execute any of the trusts or powers hereunder or perform any

with the execution and performance of its duties hereunder, and in no event shall the Trustee or the Certificate Administrator
be liable for punitive, special, 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, as applicable, has been advised of the likelihood of such
loss or damage.

 

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

 

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

Administrator may be enforced by such party without the possession of any of the Certificates, or the production thereof at the
trial or other proceeding relating thereto, and any such suit, action or proceeding instituted by the Trustee or the Certificate
Administrator, as applicable, shall be brought in its name for the benefit of all the Holders of such Certificates, subject to
the provisions of this Agreement.

 

(d)           In
order to comply with the laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions,
including those relating to the funding of terrorist activities and money laundering (“Applicable Laws”), the
Trustee and the Certificate Administrator, as applicable, is required to obtain, verify and record certain information relating
to individuals and entities which maintain a business relationship with the Trustee and the Certificate Administrator, as applicable.
Accordingly, each of the parties agrees to provide to the Trustee and the Certificate Administrator, as applicable, upon its request

8.3.          Neither the Trustee nor the Certificate Administrator is Liable for Certificates or the Trust Loan. The recitals

assume no responsibility for their correctness. The Trustee and the Certificate Administrator make no representations as to the
validity or sufficiency of this Agreement, the Certificates, the Whole Loan or the Companion Loans or related documents except
as expressly set forth herein. The Trustee and the Certificate Administrator shall not be liable for any action or failure of any

the efficacy of the Trust Fund or its ability to generate the payments to be distributed to Certificateholders under this Agreement,
including, without limitation, the existence, condition and ownership of the Property; the existence and enforceability of any
hazard insurance thereon; the validity of the assignment of the Trust Loan to the Trust; the performance or enforcement of the
Whole Loan (other than with respect to the Servicer or Special Servicer, if the Trustee shall assume the duties of the Servicer
and/or Special Servicer, respectively, pursuant to Section 7.2 and then only to the extent of the obligations of the
Servicer or Special Servicer, as applicable, hereunder); the compliance by the Depositor, the Borrower, the Servicer and the Special
Servicer with any warranty or representation made under this Agreement or in any related document or the

 

    -181-

     

    

 

accuracy of any such warranty
or representation made under this Agreement or in any related document prior to the Trustee’s receipt of notice or other
discovery by a Responsible Officer of the Trustee of any noncompliance therewith or any breach thereof; any investment of monies
by or at the direction of the Servicer or the Special Servicer or any loss resulting therefrom (other than investments made with
the Trustee or the Certificate Administrator in its commercial capacity); the failure of the Servicer, the Special Servicer or
any sub-servicer to act or perform any duties required of it hereunder; or any action by the Trustee or the Certificate Administrator
taken at the direction of the Servicer or the Special Servicer (other than with respect to the Trustee if the Trustee shall assume
the duties of the Servicer or the Special Servicer, respectively); provided, however, that the foregoing shall not
relieve the Trustee or the Certificate Administrator, as applicable, of its obligation to perform its duties under this Agreement.
Except with respect to a claim based on either the Trustee’s or the Certificate Administrator’s negligent action, negligent
failure to act, bad faith or willful misconduct (or such other standard of care as may be provided herein with respect to any particular
matter), no recourse shall be had for any claim based on any provisions of this Agreement, the Certificates, the Mortgage, the
Property, the Collateral Security Documents or the Whole Loan or assignment thereof against the Trustee or the Certificate Administrator,
as applicable, in its respective individual capacity, and neither the Trustee nor the Certificate Administrator shall have any
personal obligation, liability or duty whatsoever to any Certificateholder or any other Person with respect to any such claim,
and any such claim shall be asserted solely against the Trust Fund or any indemnitor who shall furnish indemnity as provided in
this Agreement. Neither the Trustee nor the Certificate Administrator shall have any responsibility for filing any financing or
continuation statements in any public office at any time or to otherwise perfect or maintain the perfection of any security interest
or lien granted to it hereunder or to record this Agreement (unless, with respect to the Trustee, the Trustee shall have become
the successor Servicer or Special Servicer). Neither the Trustee nor the Certificate Administrator shall be accountable for the
use or application by the Depositor of any of the Certificates or of the proceeds of such Certificates or for the use or application
of any funds paid to the Servicer or the Special Servicer, as applicable, in respect of the Whole Loan deposited into or withdrawn
from the Collection Account or any account maintained by or on behalf of the Servicer (except to the extent that the Collection
Account or such other account is held by the Trustee or the Certificate Administrator in their commercial capacity), or for investment
of such amounts (other than investments made with the Trustee or the Certificate Administrator in their commercial capacity).

 

The Trustee and the Certificate
Administrator, by reason of the action or inaction of its directors, officers, members, managers, partners, employees or agents
shall have no liability to the Trust or the Certificateholders for any action taken or for refraining from the taking of any action
in good faith pursuant to this Agreement for actions taken or not taken at the direction of Certificateholders, or for errors in
judgment; provided, however, that this provision shall not protect the Trustee, the Certificate Administrator or
any such Person against any liability which would otherwise be imposed by reason of willful misconduct, bad faith or negligence
of the Trustee, the Certificate Administrator or any such Person. The Trustee, the Certificate Administrator and any of their respective
directors, officers, members, managers, partners, employees, Affiliates, agents or Controlling Persons shall be indemnified by
the Trust pursuant to Section 3.4(c) out of amounts on deposit in the Collection Account, and held harmless against
any loss, liability, claim, demand or expense incurred in connection with any legal action or other claims, costs, expenses, losses,

liabilities incurred in connection with or related to the Trustee’s or the Certificate
Administrator’s performance of their powers and duties under this Agreement (including, without limitation, performance under
Section 8.1 hereof) or in connection with the Whole Loan, the Property or the Certificates; provided, however,
that this provision shall not protect the Trustee, the Certificate Administrator or any such Person against any liability which
would otherwise be imposed by reason of willful misconduct, bad faith or negligence of the Trustee, the Certificate Administrator
or any such Person. The indemnification provided hereunder shall survive the resignation or removal of the Trustee or the Certificate
Administrator and the termination of this Agreement. Anything herein to the contrary notwithstanding, the Trustee shall be responsible
for its acts or failure to act as Servicer and/or Special Servicer during the time the Trustee is serving as such pursuant and
subject to the terms of this Agreement.

 

8.4.          Trustee
and Certificate Administrator May Own Certificates. The Trustee and the Certificate Administrator in their individual or any
other capacity may become the owner or pledgee of Certificates with the same rights, powers, and privileges as it would have if

8.5.          Trustee’s
and Certificate Administrator’s Fees and Expenses.
(a) The Certificate Administrator shall be entitled to the Certificate Administrator Fee (including that portion of the
Certificate Administrator Fee that represents the Trustee Fee, which is payable to the Trustee), payable pursuant to Section 3.4(c).
The Certificate Administrator 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 Certificate Administrator’s and the Trustee’s sole form of
compensation for all services rendered by each entity in the execution of the trust hereby created and in the exercise and
performance of any of the powers and duties of the Certificate Administrator and the Trustee hereunder. The Trustee and the
Certificate Administrator shall be entitled to be reimbursed for all reasonable expenses and disbursements incurred or made
by the Trustee or the Certificate Administrator, as applicable, in accordance with any of the provisions of this Agreement
(including the fees and expenses of its counsel and of all Persons not regularly in its employ), provided such cost
would qualify as an “unanticipated expense incurred by the REMIC” within the meaning of the REMIC Provisions,
except any such expense, disbursement or advance as may arise from its negligence, willful misconduct or bad faith or which
is expressly the responsibility of a Certificateholder or Certificateholders hereunder, all of which reimbursements to be
paid from amounts on deposit in the Collection Account pursuant to Section 3.4(c); provided, however,
that neither the Trustee nor the Certificate Administrator shall refuse to perform any of their obligations hereunder solely
as a result of the failure to be paid any fees and expenses so long as payment of such fees and expenses are reasonably
assured to it. The Trustee and the Certificate Administrator shall provide the Servicer with an invoice, on or prior to each
Payment Date, setting forth the actual expenses incurred in connection with the performance of its duties hereunder for which
it seeks payment or reimbursement. Notwithstanding any other provision of this Agreement, neither the Trustee nor the
Certificate Administrator shall be entitled to reimbursement from the Trust for an expense incurred under this Agreement in
connection with the performance of its ordinary and regularly recurring duties hereunder unless such reimbursement is
expressly provided for herein or otherwise permitted hereunder.

trust powers and to accept the trust conferred under this Agreement, which has a combined capital and surplus of at least $50,000,000
and (i) have a rating on its unsecured long-term debt of at least “A” by S&P or otherwise acceptable to S&P

Servicer and/or Special Servicer pursuant to Section 7.2). If a corporation, association or trust company publishes
reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority,
then for purposes of this Section the combined capital and surplus of such entity shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In the event that the place of business from which the
Trustee or the Certificate Administrator, as applicable, administers the Trust Fund is a state or local jurisdiction that imposes
a tax on the Trust, the Trustee or the Certificate Administrator, as applicable, shall elect either to (i) resign immediately
in the manner and with the effect specified in Section 8.7, (ii) pay such tax from its own funds and continue
as Trustee or the Certificate Administrator, as applicable, or (iii) administer the Trust Fund from a state and local jurisdiction

directors, officers and employees acting on behalf of the Certificate Administrator in connection with its activities under this
Agreement; provided that if the Certificate Administrator is not rated at least “A-” or its equivalent by S&P
and its equivalent by Morningstar (if then rated by Morningstar), such applicable error and omissions insurance policy must be
rated at least “A-” or its equivalent by S&P and Morningstar (if then rated by Morningstar). Such insurance policy
shall protect the Certificate Administrator against losses, forgery, theft, embezzlement, fraud, errors and omissions of such covered
persons. The amount of coverage shall be at least equal to the coverage that is required by applicable governmental authorities
having regulatory power over the Certificate Administrator. In the event that any such bond or policy ceases to be in effect, the
Certificate Administrator shall obtain a comparable replacement bond or policy. In lieu of the foregoing, the Certificate Administrator
shall be entitled to self-insure with respect to such risks so long as (a) the Certificate Administrator is rated at least
“A-” or its equivalent by S&P and Morningstar (if then rated by Morningstar) or (b) each Rating Agency has

by applicable governmental authorities having regulatory power over the Trustee. In the event that any such bond or policy ceases
to be in effect, the Trustee shall obtain a comparable replacement bond or policy. In lieu of the foregoing, the Trustee shall
be entitled to self-insure with respect to such risks so long as (a) the Trustee’s unsecured long-term debt is
rated at least “A-” or its equivalent by S&P and Morningstar (if then rated by Morningstar) or (b) each Rating
Agency has confirmed as evidenced by the receipt of a Rating Agency Confirmation.

 

8.7.          Resignation
and Removal of the Trustee or the Certificate Administrator. Each of the Trustee and the Certificate Administrator may at

occur: (x) the Trustee or Certificate Administrator shall cease to be eligible in accordance with the provisions of Section 8.6
and shall fail to resign after written request for the Trustee’s or the Certificate Administrator’s resignation by
the Depositor, the Servicer or the Special Servicer, as applicable; (y) the Trustee or the Certificate Administrator shall

the Trustee in respect of the receipt, custody, investment and payment of monies shall be exercised solely by the Trustee; (ii) all
other rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed and exercised
or performed by the Trustee and such co-trustee or trustees and separate trustee or trustees jointly except to the extent that
under any law of any jurisdiction in which any particular act or acts are to be performed, the Trustee shall be incompetent or
unqualified to perform such act or acts, in which event such rights, powers, duties and obligations shall be exercised and performed
by such co-trustee or trustees; (iii) no power hereby given to, or exercisable by, any such co-trustee or separate trustee
shall be exercised hereunder by such co-trustee or separate trustees except jointly with, or with the consent of, the Trustee;
and (iv) no trustee hereunder shall be personally liable by reason of any act or omission of any other trustees hereunder.

 

If, at any time, the Trustee
shall deem it no longer necessary or prudent in order to conform to any such law, the Trustee shall execute and deliver all instruments
and agreements necessary or proper to remove any co-trustee or separate trustee. Notwithstanding the foregoing, the appointment
of a co-trustee or separate trustee by the Trustee shall not relieve the Trustee of its obligations, duties, or responsibilities
in any way or to any degree.

 

    -188-

     

    

 

(e)           Any request, approval or consent in writing by the Trustee to any co-trustee or separate trustee shall be sufficient
warrant to such co-trustee or separate trustee, as the case may be, to take such action as may be so required, approved or consented
to.

 

(f)            Notwithstanding any other provision of this Section 8.10, the powers of any co-trustee or separate trustee shall
not exceed those of the Trustee hereunder, and such co-trustee or separate trustee must meet the eligibility requirements set forth
in Section 8.6.

 

8.11.        Appointment of Authenticating Agent. (a)  The Certificate Administrator may appoint an agent or agents
which shall be authorized to act on behalf of the Certificate Administrator to authenticate Certificates (each such agent, an “Authenticating
Agent”), and Certificates so authenticated shall be entitled to the benefits of this Agreement and shall be valid and
obligatory for all purposes as if authenticated by the Certificate Administrator hereunder. Wherever a reference is made in this
Agreement to the authentication and delivery of Certificates by the Certificate Administrator or the Certificate Administrator’s
certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Certificate
Administrator by an Authenticating Agent and a certificate of authentication executed on behalf of the Certificate Administrator
by an Authenticating Agent. Each Authenticating Agent shall, at all times, be a corporation or association organized and doing
business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such law
to act as Authenticating Agent, having a combined capital and surplus of not less than $15,000,000, authorized under such laws
to do trust business and subject to supervision or examination by federal or state authorities. If such Authenticating Agent publishes
reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If, at any time, an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section. The initial Authenticating Agent shall be the Certificate Administrator.

 

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

 

(c)           An Authenticating Agent may resign at any time by giving at least 30 days’ advance written notice thereof to the Certificate
Administrator, the Servicer or Special Servicer, as applicable, and the Depositor. The Certificate Administrator may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent, the Servicer or
Special Servicer, as applicable, and the Depositor. Upon receiving such a notice of resignation or upon such a termination, or
in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the
Certificate Administrator may appoint a successor Authenticating Agent and shall mail

 

    -189-

     

    

 

written notice of such appointment by first
class mail, postage prepaid to all Certificateholders as their names and addresses appear in the Certificate Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of
its predecessor hereunder, with like effect as if originally named as an Authenticating Agent herein. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

 

8.12.        Indemnification by Trustee and the Certificate Administrator. The Trustee, and the Certificate Administrator, as
applicable, shall indemnify and hold harmless the Trust, the Depositor, the Servicer and the Special Servicer (each, for the purposes
of this Section 8.12 only, an “Indemnified Party”), from and against any claims, losses, damages, penalties,
fines, forfeitures, legal fees and expenses and related costs, judgments and other costs and expenses incurred by the Indemnified
Party in connection with this Agreement (including, without limitation, reasonable fees and disbursements of counsel incurred by
the Indemnified Party in any action or proceeding between the Indemnifying Party and the Indemnified Party or between the Indemnified
Party and any third party or otherwise) that arise out of or are based upon (i) a breach by the Trustee or the Certificate Administrator
of its representations and warranties made under this Agreement, or (ii) the negligence, bad faith, fraud or willful misconduct
on the part of the Trustee or the Certificate Administrator in the performance of its obligations or negligent disregard of its
obligations and duties under this Agreement.

 

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

 

8.13.        Certificate Administrator and Servicer Not Responsible for Inconsistent Payment Information. In connection with any
Distribution Date and a voluntary prepayment or the payment at maturity by the Borrower of the Whole Loan or any portion thereof,
the Certificate Administrator shall report the amount of such prepayment or payment to the Depository based on information received
from the Servicer or Special Servicer in reliance on notices received from the Borrower. In the event of any inconsistencies in
payments or prepayments made by the Borrower with the previously delivered notices by the Borrower, all costs and expenses incurred
as a result of a failure by the Borrower to make any such payments or prepayment, shall be paid by the Borrower in accordance with
the Loan Agreement; provided that the amount of payment reported to the Depository by the Certificate Administrator was
consistent with the information received from the Servicer or Special Servicer. If the Borrower fails to do so, such costs and
expenses shall be reimbursed to the Certificate Administrator and to the Servicer or Special Servicer, as applicable, by the Trust
pursuant to Section 3.4(c) from funds on deposit in the Collection Account. Neither the Certificate Administrator,
the Servicer nor the Special Servicer shall be liable for any inability or delay of the Depository to make a distribution as a
result of such inconsistencies. Notwithstanding the foregoing, the Certificate Administrator

 

    -190-

     

    

 

shall notify the Depository on the
Remittance Date or as soon as reasonably possible of any such inconsistencies.

 

8.14.        Access to Certain Information. (a)  The Certificate Administrator shall afford to any Privileged Person

Such access shall be afforded without charge but
only upon reasonable prior written request and during normal business hours at the offices of the Certificate Administrator.

 

The Certificate Administrator
will provide copies of the items described in this Section 8.14(a) above upon reasonable written request of the Privileged
Persons. The Certificate Administrator may require payment for the reasonable costs and expenses of providing the copies and may
also require a confirmation executed by the requesting Person, in a form reasonably acceptable to the Certificate Administrator,
to the effect that the Person making the request is a Beneficial Owner or prospective purchaser of Certificates, is requesting
the information solely for use in evaluating its investment in the Certificates and will otherwise keep the information confidential.
Certificateholders, by the acceptance of their Certificates, will be deemed to have agreed to keep this information confidential.

9.2.          Limitation on Liability of Directing Holder and Risk Retention Consultation Party; Acknowledgements of the Certificateholders.

 

None of the Controlling Class,
the Directing Holder or the Risk Retention Consultation Party shall be liable to the Trust Fund or the Certificateholders for any
action taken, or for refraining from the taking of any action for errors in judgment.

 

By its acceptance of a Certificate,
each Certificateholder acknowledges and agrees that the Directing Holder, the Holders of the Certificates in the Controlling Class
and the Risk Retention Consultation Party (i) may each have special relationships and interests that conflict with those of Certificateholders
of one or more Classes of the Certificates, including owning any interest in the Mezzanine Loan, (ii) may act solely in its

or liability to the Trust or the Holders of any Class of Certificates, (iv) may take actions that favor the interests of the
Companion Loans or the interests of one or more Classes of the Certificates or of the RR Interest over other Classes of the Certificates,
(v) shall have no liability whatsoever to the Trust, the other parties to hereto, the Certificateholders or any other person (including
any Borrower Affiliate) for having acted in accordance with or as permitted under the terms of this Agreement, and the Certificateholders
may not take any action whatsoever against the Directing Holder, the holders of the Certificates in the Controlling Class, the
Risk Retention Consultation Party or any of the respective affiliates, directors, officers, shareholders, members, partners, agents
or principals of the Directing Holder, the holders of the Certificates in the Controlling Class or the Risk Retention Consultation
Party as a result of the Directing Holder, the holders of the Certificates in the Controlling Class or the Risk Retention Consultation
Party having acted in accordance with the terms of and as permitted hereunder.

 

9.3.          Rights and Powers of the Directing Holder and the Risk Retention Consultation Party.

 

(a)            Notwithstanding anything herein to the contrary, except as set forth in, and in any event subject to, Section 3.24(d)
and (e), Section 9.3(b), Section 9.3(c) and the second (2nd) and third (3rd) paragraphs of this Section
9.3(a), (i) the Servicer shall not be permitted to take any of the actions constituting a Major Decision unless it has obtained
the consent of the Special Servicer, which consent will be deemed given if the Special Servicer does not object

 

    -202-

     

    

 

within 15 Business
Days (or 90 days with regard to the determination of an Acceptable Insurance Default) unless such actions are part of an Asset
Status Report approved by the Directing Holder under Section 3.10(h) (after delivery of a written recommendation and analysis
to the Special Servicer and information reasonably requested by the Special Servicer), (ii) for so long as a Subordinate Control
Period is in effect, the Special Servicer shall not be permitted to (A) consent to the Servicer’s taking any of the actions
constituting a Major Decision, or (B) take any of the actions constituting a Major Decision, but subject to Section 3.10(h)
as to which the Directing Holder has objected in writing within ten (10) Business Days after receipt of the written recommendation
and analysis and information reasonably requested by the Directing Holder from the Special Servicer (provided that if such
written objection has not been received by the Special Servicer within such ten (10) Business Day period, then the Directing Holder
shall be deemed to have approved such action) and (iii) the Special Servicer will also be required to consult on a non-binding
basis with the Risk Retention Consultation Party (unless the Risk Retention Consultation Party is a Borrower Related Party). In
the event that the Special Servicer or Servicer, as applicable, determines that immediate action, with respect to a Major Decision,
or any other matter requiring consent of the Directing Holder during any Subordinate Control Period or consultation with the Directing
Holder or Risk Retention Consultation Party during any Subordinate Consultation Period under this Agreement, is necessary to protect
the interests of the Certificateholders, the Special Servicer or Servicer, as applicable may take any such action without waiting
for the Directing Holder’s or the Risk Retention Consultation Party’s response. The Special Servicer is not required
to obtain the consent of the Directing Holder for any Major Decision during any Subordinate Consultation Period; provided,
that, during any Subordinate Consultation Period, the Special Servicer shall consult with the Directing Holder in connection with
any Major Decision (and such other matters that are subject to consent, approval, direction or non-binding consultation rights
of the Directing Holder hereunder) and consider alternative actions recommended by the Directing Holder, in respect thereof; provided,
further, that the Special Servicer shall consult with the Risk Retention Consultation Party in connection with any Major
Decision and consider alternative actions recommended by the Risk Retention Consultation Party in respect thereof.

 

In addition, for so long as a
Subordinate Control Period is in effect, subject to Section 9.3(b), Section 9.3(c) and the immediately following
paragraph, the Directing Holder may direct the Special Servicer to take, or to refrain from taking, such other actions with respect
to the Whole Loan as the Directing Holder may reasonably deem advisable.

 

If the Special Servicer or Servicer,
as applicable, determines that a refusal to consent by the Directing Holder or any direction or advice from the Directing Holder
or Risk Retention Consultation Party would (A) otherwise require or cause the Special Servicer or Servicer, as applicable, to violate
the terms of the Loan Documents, applicable law, provisions of the Code resulting in an Adverse REMIC Event or this Agreement,
(including without limitation, actions inconsistent with Accepted Servicing Practices), or (B) expose any Certificateholder, the
Servicer, the Special Servicer, the Certificate Administrator, the Trustee or the Trust or their respective Affiliates, officers,
directors or agent to any claim, suit or liability, (C) result in the imposition of a tax upon the Trust or loss of REMIC status
or (D) materially expand the scope of the Special Servicer’s, the Servicer’s, the Trustee’s or the Certificate
Administrator’s responsibilities hereunder, then the Special Servicer or Servicer, as applicable, shall disregard such refusal
to consent, direction or advice and notify the Directing Holder or the

 

    -203-

     

    

 

Risk Retention Consultation Party, as applicable, and the
Trustee, the Certificate Administrator and the 17g-5 Information Provider of its determination, including a reasonably detailed
explanation of the basis therefor. The taking of, or refraining from taking, any action by the Servicer or Special Servicer in
accordance with the direction of or approval of the Directing Holder or Risk Retention Consultation Party that does not violate
the Loan Documents, this Agreement, any applicable law, provisions of the Code resulting in an Adverse REMIC Event or Accepted
Servicing Practices or any other provisions of this Agreement, shall not result in any liability on the part of the Servicer or
the Special Servicer. The Servicer may request that the Certificate Administrator provide the names of the Majority Controlling
Class Certificateholders, and the Servicer will be able to conclusively rely on such information.

 

(b)           Notwithstanding anything to the contrary contained herein (i) after the termination of a Subordinate Control Period,
the Directing Holder shall have no right to consent to or direct any action taken or not taken by any party to this Agreement;
(ii) during any Subordinate Consultation Period, the Directing Holder shall remain entitled to receive any notices, reports
or information to which it is entitled pursuant to this Agreement, and the Servicer, Special Servicer and any other applicable
party shall consult with the Directing Holder in connection with any action to be taken or refrained from taking to the extent
set forth herein; and (iii) after the termination of any Subordinate Consultation Period, the Directing Holder shall have
no direction, consultation or consent rights hereunder and no right to receive any notices, reports or information (other than
notices, reports or information required to be delivered to all Certificateholders) or any other rights as Directing Holder.

 

If a Subordinate Control Period
is again in effect following the termination of such period, then the Companion Loan Holders or the Controlling Class, as applicable,
shall regain all the consent and direction rights of the Controlling Class set forth in this Agreement (including, without limitation,
the right to appoint a Directing Holder).

 

(c)            For purposes of determining the Directing Holder, exercising any rights of the Controlling Class or the Directing Holder
or receiving Asset Status Reports or any other information under this Agreement other than Distribution Date Statements, any holder
of any interest in a Controlling Class Certificate who is a Borrower, a property manager or an agent or Affiliate of the foregoing
shall not be deemed to be a holder of the related Controlling Class and shall not be entitled to exercise such rights or receive
such information. If, as a result of the preceding sentence, no holder of Controlling Class Certificates would be eligible to exercise
such rights, there will be no Directing Holder.

 

9.4.          Directing Holder Contact with Servicer and Special Servicer.

 

Upon reasonable request, each
of the Servicer and the Special Servicer shall, without charge, make a Servicing Officer available to answer questions from the
Directing Holder (during any Subordinate Control Period) regarding the performance and servicing of the Whole Loan (or, in the
case of the Special Servicer, the Special Servicer’s operational activities on a platform level basis related to the servicing
of the Whole Loan after a Special Servicing Loan Event and the servicing of any Foreclosed Property) for which the Servicer or
the Special Servicer, as the case may be, is responsible.

 

    -204-

     

    

 

Notwithstanding any provision
of this Agreement to the contrary, the failure of the 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 if the Servicer or the Special
Servicer, as applicable, determines, in its reasonable and good faith judgment and consistent with the Accepted Servicing Practices,
that such disclosure would constitute a waiver of the attorney-client privilege on behalf of the Trust or the Trust Fund or otherwise
materially harm the Trust or the Trust Fund.

mailed as soon as practicable specifying (A) the final Distribution Date upon which final payment of the Certificates shall

unless the Certificate Administrator has received at the expense of the Trust Fund, an Opinion of Counsel that any other manner
of terminating either the Lower-Tier REMIC or the Upper-Tier REMIC will not subject the Trust Fund, the Lower-Tier
REMIC or the Upper-Tier REMIC to federal income tax:

Lower-Tier REMIC or the Upper-Tier 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 Lower-Tier
REMIC or the Upper-Tier REMIC that would be a claim against the Lower-Tier REMIC or the Upper-Tier REMIC or the Grantor Trust;
provided that the Trustee, the Certificate Administrator and the Depositor have received an Opinion of Counsel (at the
expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such qualification

the interests of any holder of the Certificates (including, for the avoidance of doubt, any Holder of an RR Interest) or holder

(viii)        to modify the provisions hereof with respect to reimbursement of Nonrecoverable Advances if (a) the Depositor, the
Certificate Administrator, the Servicer, and, to the extent that the Trustee has the obligation to make Advances, the Trustee,
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 will not cause the Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust, as evidenced by an Opinion of Counsel (at the expense
of the party requesting the amendment or at the expense of the Trust Fund if the Trustee is the requesting party), (c) Rating

not less than 51% of the aggregate Percentage Interests constituting the Class and any Companion Loan Holder if materially and
adversely affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions
of this Agreement or of modifying in any manner the rights of the holders of the Certificates, except that the amendment may not
directly (i) reduce in any manner the amount of, or delay the timing of, payments which are required to be distributed on any Certificate
without the consent of the holder of such Certificate or which are required to be distributed to any Companion Loan Holder without
the consent of each Companion Loan Holder, (ii) reduce the aforesaid percentage of Certificates of any Class the holders of which
are required to consent to the amendment, without the consent of the holders of all Certificates of that Class then outstanding

(c)            Notwithstanding any contrary provision contained in this Agreement, no amendment to this Agreement may be made that changes
in any manner the rights and/or obligations of the Loan Seller under this Agreement or under the Loan Purchase Agreement without
the consent of the Loan Seller, or the rights of any Initial Purchaser hereunder without the written consent of such Initial Purchaser
or that adversely affects the rights (including, without limitation, as a third party beneficiary hereunder) and/or the obligations,
if any, of a Companion Loan Holder hereunder without the consent of such Companion Loan Holder, and the Trustee and Certificate
Administrator may, but will not be obligated to, enter into any amendment to this Agreement that it determines affects its rights,
duties or immunities or creates any additional liability for the Certificate Administrator and Trustee under this Agreement.

 

(d)           It shall not be necessary for the consent of Certificateholders under this Section 11.1 to approve the particular
form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining
such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Certificate Administrator may prescribe.

 

(e)            Notwithstanding the foregoing, no amendment may be made to this Agreement unless the Certificate Administrator, the Trustee,
the Servicer and the Special Servicer have first received an Opinion of Counsel (at the expense of the requesting party, if

 

    -208-

     

    

 

applicable,
and otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)
to the effect that the amendment is authorized or permitted under this Agreement and all conditions precedent have been met and
that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor, the Trustee, the
Certificate Administrator or any other specified person in accordance with the amendment, will not result in the imposition of
any tax on any portion of the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify as a REMIC
or cause the Grantor Trust to fail to qualify as a grantor trust under the Code.

 

(f)            Promptly after the execution of any amendment to this Agreement, the Certificate Administrator shall post a copy of the
same to the Certificate Administrator’s Website, deliver a copy of the same to the 17g-5 Information Provider who shall post
a copy of the same on the 17g-5 Information Provider’s Website pursuant to Section 8.14(b), and thereafter, the
Certificate Administrator shall furnish written notification of the substance of such amendment to each Certificateholder, the
Depositor, the Servicer, the Special Servicer, the Borrower, the Initial Purchasers and the Rating Agencies.

 

(g)           In the event that neither the Depositor nor any successor thereto is in existence, any amendment under this Section 11.1
shall be effected with the consent of the Trustee, the Certificate Administrator and the Servicer or Special Servicer, as applicable,
and, to the extent required by this Section 11.1, the required Certificateholders.

 

(h)           Unless otherwise specified in Section 11.1(a), the costs and expenses associated with any such amendment, including
without limitation, Opinions of Counsel and Rating Agency Confirmations, shall be borne by the party requesting such amendment
(or, if such amendment is required by any of the Rating Agencies to maintain the rating issued by it or requested by the Trustee
or the Certificate Administrator for any purpose described in Section 11.1(a) (which do not modify or otherwise relate
solely to the obligations, duties or rights of the Trustee or the Certificate Administrator), then at the expense of the Depositor
and, if neither the Depositor nor any successor thereto is in existence, the Trust Fund).

applicable recording office, is subject to recordation in all appropriate public offices for real property records in the county
in which the Property subject to the Mortgage is situated, and in any other appropriate public recording office or elsewhere, such
recordation to be effected by the Trustee or the Certificate Administrator at the expense of the Trust upon its receipt of an Opinion
of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders of the
Trust.

 

(b)           For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement
may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and
such counterparts shall constitute but one and the same instrument. Delivery of an executed counterpart of a signature page of

the Rating Agencies at the addresses set forth below; provided, however, that such information is first provided

11.6.        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, to the extent permitted by applicable law, 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.

 

11.7.        Limitation on Rights of Certificateholders. The death or incapacity of any Certificateholder shall not operate to
terminate this Agreement or the Trust Fund, nor entitle such Certificateholder’s legal representative or heirs to claim an
accounting or to take any action or to commence any proceeding in any court for a petition or winding up of the Trust Fund, or
otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

 

No Certificateholder, solely
by virtue of its status as a Certificateholder, shall have any right to vote (except as provided herein) or in any manner otherwise
control the operation and management of the Trust Fund, or the obligations of the parties hereto, nor shall anything herein set
forth or contained in the terms of the Certificates be construed so as to constitute the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholders be under any liability to any third party by reason of
any action by the parties to this Agreement pursuant to any provision hereof.

 

No Certificateholder, solely
by virtue of its status as a Certificateholder, shall have any right by virtue or by availing itself of any provisions of this
Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless
such Holder previously shall have given to the Trustee a written notice of a Servicer Termination Event or Special Servicer Termination
Event, as the case may be, and of the continuance thereof, as herein before provided, and unless the Holders of Certificates aggregating
not less than 25% of the Voting Rights of the Certificates shall also have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and shall 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 60 days
after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action,
suit or proceeding; it being understood and

 

    -215-

     

    

 

intended, and being expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue
or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders
of any other of the Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder except as
provided herein with respect to entitlement to payments or to enforce any right under this Agreement, except in the manner herein
provided and for the common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section,
each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

 

11.8.        Certificates Nonassessable and Fully Paid. The Certificateholders shall not be personally liable for obligations
of the Trust Fund, the interests in the Trust Fund represented by the Certificates shall be nonassessable for any reason whatsoever,
and the Certificates, upon due authentication thereof by the Certificate Administrator pursuant to this Agreement, are and shall
be deemed fully paid.

 

11.9.        Reproduction of Documents. This Agreement and all documents relating thereto, including, without limitation, (i) consents,
waivers and modifications which may hereafter be executed, (ii) documents received by any party at the closing, and (iii) financial
statements, certificates and other information previously or hereafter furnished, may be reproduced by any photographic, photostatic,
microfilm, micro-card, miniature photographic or other similar process. The parties agree that any such reproduction shall be admissible
in evidence as the original itself in any judicial or administrative proceeding, whether or not the original is in existence and
whether or not such reproduction was made by a party in the regular course of business, and that any enlargement, facsimile or
further reproduction of such reproduction shall likewise be admissible in evidence.

 

11.10.      No Partnership. Nothing herein contained shall be deemed or construed to create a partnership or joint venture between
the parties hereto.

 

11.11.      Actions of Certificateholders. (a)  Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Agreement to be given or taken by Certificateholders may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Certificateholders in person or by agent duly appointed in writing;
and except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered
to the Certificate Administrator and, where required, to the Depositor, the Trustee, the Servicer or the Special Servicer. Proof
of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement
and conclusive in favor of the Certificate Administrator, the Trustee, the Depositor, the Servicer and the Special Servicer if
made in the manner provided in this Section.

 

(b)           The fact and date of the execution of any Certificateholder of any such instrument or writing may be proved in any reasonable
manner which the Certificate Administrator deems sufficient.

 

    -216-

     

    

 

(c)            Any request, demand, authorization, direction, notice, consent, waiver, or other act by a Certificateholder shall bind every
Holder of every Certificate issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, in respect
of anything done, or omitted to be done, by the Trustee, the Certificate Administrator, the Depositor, the Servicer or the Special
Servicer in reliance thereon, whether or not notation of such action is made upon such Certificate.

 

(d)           The Certificate Administrator may require additional proof of any matter referred to in this Section as it shall deem reasonably
necessary.

 

11.12.      Successors and Assigns. The rights and obligations of any party hereto shall not be assigned (except pursuant to
Section 6.2, 6.4, 8.7 or 8.9 hereof) by such party without the prior written consent of the other
parties hereto. This Agreement shall inure to the benefit of and be binding upon the Depositor, the Servicer, the Special Servicer,
the Certificate Administrator and the Trustee and their respective permitted successors and assigns. No Person other than a party
to this Agreement, the Initial Purchasers and any Certificateholder shall have any rights with respect to the enforcement of any
of the rights or obligations hereunder. Without limiting the foregoing, the parties to this Agreement specifically agree that (i)
the Loan Seller shall be a third-party beneficiary of this Agreement with respect to any provisions relating to the Loan Seller,
(ii) each Companion Loan Holder shall be a third-party beneficiary of this Agreement with respect to any provisions relating to
the Companion Loan Holders, (iii) each Senior Companion Loan Depositor and Senior Companion Loan Exchange Act Reporting Party shall
be a third-party beneficiary of this Agreement with respect to its rights under Article 13 and (iv) no Borrower, property manager
or other party to the Trust Loan is an intended third-party beneficiary of this Agreement (provided that the Borrower shall
be entitled to notices to the extent expressly provided herein).

 

11.13.      Acceptance by Authenticating Agent, Certificate Registrar and Custodian. The Certificate Administrator hereby accepts
its appointment as Authenticating Agent, Certificate Registrar and Custodian and agrees to perform the obligations required to
be performed by it in each such capacity pursuant to the terms of this Agreement.

 

11.14.      Streit Act. Any provisions required to be contained in this Agreement by Section 126 and/or Section 130-k
or Article 4-A of the New York Real Property Law are hereby incorporated herein, and such provisions shall be in addition to those
conferred or imposed by this Agreement; provided, however, that to the extent that such Section 126 and/or 130-k
shall not have any effect, and if said Section 126 and/or Section 130-k should at any time be repealed or cease to apply
to this Agreement or be construed by judicial decision to be inapplicable, said Section 126 and/or Section 130-k shall
cease to have any further effect upon the provisions of this Agreement. In a case of a conflict between the provisions of this
Agreement and any mandatory provisions of Article 4-A of the New York Real Property Law, such mandatory provisions of said Article
4-A shall prevail, provided that if said Article 4-A shall not apply to this Agreement, should at any time be repealed,
or cease to apply to this Agreement or be construed by judicial decision to be inapplicable, such mandatory provisions of such
Article 4-A shall cease to have any further effect upon the provisions of this Agreement.

 

    -217-

     

    

 

11.15.      Assumption by Trust of Duties and Obligations of the Lender Under the Loan Documents. The Trustee and Certificate
Administrator on behalf of the Trust as assignee of the Trust Loan and the Servicer and Special Servicer hereby acknowledge that
the Trust assumes all of the rights and obligations of the Lender as lender under the Loan Documents and agrees to be bound thereby,
and in accordance with the terms thereof. Such acknowledgement on behalf of the Trust is made by the Trustee, the Certificate Administrator,
the Servicer and the Special Servicer in the exercise of the powers and authority conferred and vested in it and is intended for
the purpose of binding only the Trust. Nothing contained in this Section shall be construed as creating any liability on the part
of the Trustee, Certificate Administrator, Servicer or Special Servicer, individually or personally, it being agreed that all liabilities
and obligations being acknowledged as assumed are solely those of the Trust, and under no circumstances shall the Trustee, Certificate
Administrator, Servicer or Special Servicer be liable personally for the breach or failure of any obligation, representation, warranty
or covenant made or undertaken by the Trust under this Agreement, any Loan Document or any related document.

 

12.        REMIC ADMINISTRATION

 

12.1.        REMIC Administration. (a)  The parties intend that each of the Lower-Tier REMIC and the Upper-Tier
REMIC shall constitute, and that the affairs of each of the Lower-Tier REMIC and the Upper-Tier REMIC shall be conducted
so as to qualify it as, a REMIC, and the provisions hereof shall be interpreted consistently with this intention.

 

(b)           The Certificate Administrator shall make or cause to be made an election on behalf of each of the Lower-Tier REMIC and
the Upper-Tier REMIC to treat the segregated pool of assets constituting such Trust REMIC as a REMIC under the Code. Each such
election shall be made on IRS Form 1066 or other appropriate federal tax or information return for the taxable year ending on the
last day of the calendar year in which the Certificates are issued.

 

(c)            The Closing Date is hereby designated as the “Startup Day” of each of the Lower-Tier REMIC and the
Upper-Tier REMIC within the meaning of Section 860G(a)(9) of the Code. The “latest possible maturity date”
of the Regular Interests and the Uncertificated Lower-Tier Interests for the purposes of Section 860G(a)(1) of the Code
is the Rated Final Distribution Date.

 

(d)           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. Within thirty days of the Closing Date, the Certificate
Administrator shall furnish or cause to be furnished to the Internal Revenue Service, on IRS Form 8811 or as otherwise may be required
by the Code, the name, title and address of the Persons that Holders of the Certificates may contact for tax information relating
thereto (and the Certificate Administrator shall act as the representative of each of the Lower-Tier REMIC and the Upper-Tier
REMIC for this purpose), together with such additional information as may be required by such Form, and shall update such information
at the time or times and in the manner required by the Code (and the Depositor agrees within (10) Business

 

    -218-

     

    

 

Days of the Closing
Date to provide any information reasonably requested by the Servicer or the Certificate Administrator and necessary to make such
filing).

 

(e)            The Certificate Administrator shall pay without any right of reimbursement the ordinary and usual expenses in connection
with the preparation, filing and mailing of tax information reports and returns that are incurred by it in the ordinary course
of its business, but extraordinary or unusual expenses, costs or liabilities incurred in connection with its tax-related duties
under this Agreement, including without limitation any expenses, costs or liabilities associated with audits or any administrative
or judicial proceedings with respect to the Lower-Tier REMIC or the Upper-Tier REMIC that involve the IRS or state tax
authorities, shall be reimbursable from the Trust Fund.

 

(f)            The Certificate Administrator shall prepare, or cause to be prepared, timely furnish or cause to be timely furnished to
the Trustee to sign (and the Trustee shall timely sign), and the Certificate Administrator shall file or cause to be filed all
federal, state and local income or franchise or other tax and information returns for each of the Lower-Tier REMIC and the
Upper-Tier REMIC as the direct representative for such REMIC. Except as provided in Section 11.1(e), the expenses
of preparing and filing such returns shall be borne by the Certificate Administrator. The Depositor shall provide on a timely basis
to the Certificate Administrator or its designee such information with respect to each of the Lower-Tier REMIC and the Upper-Tier
REMIC as is in its possession, and is reasonably requested by the Certificate Administrator to enable it to perform its obligations
under this subsection (f), and the Certificate Administrator shall be entitled to rely on such information in the performance
of its obligations hereunder.

 

(g)           The Certificate Administrator shall perform on behalf of each of the Lower-Tier REMIC and the Upper-Tier REMIC all
reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions, or other
compliance guidance issued by the IRS or any state or local taxing authority. Among its other duties, the Certificate Administrator
shall provide (i) to the IRS or other Persons (including, but not limited to, the transferor of a Class R Certificate
to a Disqualified Organization or to an agent that has acquired a Class R Certificate on behalf of a Disqualified Organization)
such information as is necessary for the application of any tax relating to the transfer of a Class R Certificate to any Disqualified
Organization and (ii) to the Certificateholders such information or reports as are required by the Code or REMIC Provisions.
The Depositor shall provide on a timely basis (and in no event later than 30 days after the Certificate Administrator’s request)
to the Certificate Administrator or its designee such information with respect to each of the Lower-Tier REMIC and the Upper-Tier
REMIC as is in its possession and is reasonably requested in writing by the Certificate Administrator to enable it to perform its
obligations under this subsection (g).

 

(h)           The Holder of the Class R Certificates holding the largest Percentage Interest therein shall be the “tax matters
person”, in the manner provided under Treasury Regulations Section 1.860F-4(d) and the “partnership representative”
within the meaning of Section 6223 of the Code (to the extent such provision is applicable to the Trust REMICs) of the Upper-Tier
REMIC and the Lower-Tier REMIC. The duties of the “tax matters person” and “partnership representative”
for the Upper-Tier REMIC and the Lower-Tier REMIC are hereby

 

    -219-

     

    

 

delegated to the Certificate Administrator as agent for the
related “tax matters person” and “partnership representative”, and the Holders of the Class R Certificates,
by acceptance of the Class R Certificates, agree, on behalf of themselves and all successor Holders of such Class R Certificates,
to such delegation to the Certificate Administrator as its agent and attorney in fact.

 

(i)            The Certificate Administrator, the Holders of the Class R Certificates, the Servicer and the Special Servicer shall
perform their obligations under this Agreement and the REMIC Provisions in a manner consistent with the status of each of the Lower-Tier
REMIC and the Upper-Tier REMIC as a REMIC.

 

(j)            The Certificate Administrator, any Holder of the Class R Certificates, the Servicer and the Special Servicer shall
not take any action or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to take any action, within their respective
control and the scope of their specific respective duties under this Agreement that, under the REMIC Provisions, could reasonably
be expected to (i) cause of either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify as a REMIC or (ii) unless
permitted under Section 12.2(a), result in the imposition of a tax upon either the Lower-Tier REMIC or the Upper-Tier
REMIC (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the
tax on prohibited contributions as defined in Section 860G(d) of the Code) (any such result in clause (i) or (ii),
an “Adverse REMIC Event”) unless (A) the Certificate Administrator and the Servicer have received a Nondisqualification
Opinion (at the expense of the party seeking to take such action or of the Trust Fund if taken for the benefit of the Certificateholders)
with respect to such action or (B) the Certificate Administrator and the Servicer have received an opinion (at the expense
of the party seeking to take such action or of the Trust Fund if taken for the benefit of the Certificateholders) to the effect
that such action will not cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify as a REMIC and that
no tax will actually be imposed.

 

(k)            Any and all federal, state and local taxes imposed on the Upper-Tier REMIC or the Lower-Tier REMIC or its assets
or transactions, including, without limitation, “prohibited transaction” taxes as defined in Section 860F of the
Code, and any tax on contributions imposed by Section 860G(d) of the Code, shall be paid from the Collection Account; provided
that the Servicer, upon two (2) days prior written notice, shall remit from the Collection Account to the Certificate Administrator
the amount of any such tax that the Certificate Administrator notifies the Servicer is due; provided, further, that
if such taxes shall have been imposed on account of the willful misconduct, bad faith or negligence of any party hereto, or in
connection with the breach of any representation or warranty made by any party hereto in this Agreement, then such taxes shall
be paid by such party.

 

(l)             The Certificate Administrator shall, for federal income tax purposes, maintain books and records with respect to the Lower-Tier
REMIC and the Upper-Tier REMIC on a calendar year and on an accrual basis. Notwithstanding anything to the contrary contained
herein or in the Loan Documents (but subject to Section 1.3), all amounts collected on the Whole Loan shall, for federal
income tax purposes, be allocated first to interest due and payable on the Whole Loan (including interest on overdue interest)
other than Default Interest. The books and records must be sufficient concerning the nature and amount of the investments of the
Lower-Tier REMIC and the Upper-Tier REMIC to show that such REMIC has complied with the REMIC Provisions.

 

    -220-

     

    

 

(m)           None of the Certificate Administrator, the Trustee, the Servicer or the Special Servicer shall enter into any arrangement
by which either the Lower-Tier REMIC or the Upper-Tier REMIC will receive a fee or other compensation for services.

 

(n)           In order to enable the Certificate Administrator to perform its duties as set forth herein, the Depositor shall provide,
or cause to be provided, to the Certificate Administrator within 10 days after the Closing Date, all information or data that the
Certificate Administrator reasonably determines to be relevant for tax purposes on the valuations and offering prices of the Certificates,
including, without limitation, the yield, issue prices, pricing prepayment assumption and projected cash flows of the Certificates
and the Class R Certificates, as applicable, and the projected cash flows on the Whole Loan. Thereafter, the Depositor, the
Trustee, the Servicer and the Special Servicer shall provide to the Certificate Administrator, promptly upon request therefor,
any such additional information or data that the Certificate Administrator may, from time to time, reasonably request in order
to enable the Certificate Administrator to perform its duties as set forth herein. The Certificate Administrator is hereby directed
to use any and all such information or data provided by the Trustee, the Depositor, the Servicer and the Special Servicer in the
preparation of all federal, state or local income, franchise or other tax and information returns and reports for each of the Lower-Tier
REMIC and the Upper-Tier REMIC to Certificateholders as required herein. The Depositor hereby indemnifies the Certificate Administrator
for any losses, liabilities, damages, claims or expenses of the Certificate Administrator arising from any errors or miscalculations
of the Certificate Administrator pursuant to this Section 12.1 that result from any failure of the Depositor to provide
or to cause to be provided, accurate information or data to the Certificate Administrator (but not resulting from the methodology
employed by the Certificate Administrator) on a timely basis and such indemnifications shall survive the termination of this Agreement
and the termination of the Certificate Administrator.

 

The Certificate Administrator
agrees that all such information or data so obtained by it shall be regarded as confidential information and agrees that it shall
use its best reasonable efforts to retain in confidence, and shall ensure that its officers, employees and representatives retain
in confidence, and shall not disclose, without the prior written consent of the Depositor, any or all of such information or data,
or make any use whatsoever (other than for the purposes contemplated by this Agreement) of any such information or data without
the prior written consent of the Depositor, unless such information is generally available to the public (other than as a result
of a breach of this Section 12.1) or is required by law or applicable regulations to be disclosed.

 

(o)           The
Certificate Administrator’s authority under this Agreement includes the authority to make, and the Certificate Administrator
is hereby directed to make, any elections allowed under the Code (i) to avoid the application of Section 6221 of the Code (or successor
provisions) to either REMIC and (ii) to avoid payment by either REMIC under Section 6225 of the Code (or successor provisions)
of any tax, penalty, interest or other amount imposed under the Code that would otherwise be imposed on any Holder of a Class R
Certificate, past or present. Holders of a Class R Certificates, by acquiring such Certificates, agree to any such elections.

 

    -221-

     

    

 

12.2.        Foreclosed Property. (a)  The parties hereto acknowledge and understand that if the Trust Fund were to
acquire the Property as Foreclosed Property and were to own and operate the Property in a manner consistent with the manner in
which the Property is currently owned and operated by the Borrower, through a Successor Manager, some portion or all of the income
derived in the Lower-Tier REMIC from such Foreclosed Property may be considered “net income from foreclosure property”
for purposes of Section 860G(c) of the Code and subject to tax at the highest corporate income tax rate.

 

In determining whether to acquire
and hold any Foreclosed Property, the Special Servicer, acting on behalf of the Trustee hereunder, shall take these circumstances
into account and shall only acquire any such Foreclosed Property if it determines, in its reasonable judgment (after, consultation
with counsel, at the expense of the Trust Fund), that either (i) there is a commercially feasible alternative method of administering
such Foreclosed Property that would not result in such tax, e.g., a net lease that results in Rents from Real Property or (ii) the
likely recovery with respect to operating the Foreclosed Property on behalf of the Trust Fund and the Companion Loan Holders, after
taking into account any such taxes that might be imposed on either the Lower-Tier REMIC or the Upper-Tier REMIC, will exceed
the likely recovery to the Trust Fund if the Trust Fund were to net lease the Foreclosed Property or were not to acquire and hold
the Foreclosed Property. If the Trust Fund acquires any Foreclosed Property, the Special Servicer, acting on behalf of the Trustee,
if the property manager would not be considered an Independent Contractor, shall either renegotiate the management agreement (if
any) or replace the property manager with a Successor Manager (as appropriate and to the extent permitted under such management
agreement) so that the Foreclosed Property would be considered to be operated by an Independent Contractor. If, after making the
foregoing reasonable efforts, the Special Servicer determines that it is in the best interests of Certificateholders on a net after-tax
basis to operate the Foreclosed Property in a manner such that the Lower-Tier REMIC or Upper-Tier REMIC shall receive,
based upon an Opinion of Counsel, “net income from foreclosure property” under the REMIC Provisions, the Special Servicer
shall maintain or cause to be maintained such records of income and expense as to enable such amounts to be computed accurately,
and shall pay or retain or cause to be paid or retained from Foreclosure Proceeds such amounts as are necessary to pay such tax
or, to the extent such amounts are insufficient, from the Collection Account pursuant to Section 3.4(c)(x).

 

Without limiting the generality
of the foregoing, the Special Servicer shall not, to the extent within its power:

 

(i)             permit the Trust Fund to enter into, renew or extend any new lease with respect to the Foreclosed 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 the Foreclosed Property, other than the completion of a building or other improvement
thereon, and then only if more than ten percent of the construction of such building or other improvements was

 

    -222-

     

    

 

completed before
default on the Whole Loan became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or

 

(iv)          Directly Operate, other than through an Independent Contractor, or allow any other Person to Directly Operate, other than
through the property manager or an Independent Contractor, the Foreclosed Property on any date more than 90 days after its acquisition
date.

 

(b)           The Special Servicer, acting on behalf of the Trustee hereunder, shall use efforts consistent with Accepted Servicing Practices
to sell the Foreclosed Property for its fair market value in accordance with Section 3.15. In any event, however, the
Special Servicer, acting on behalf of the Trustee hereunder, shall dispose of any Foreclosed Property as soon as is practicable
but in no event later than the close of the third calendar year following the year in which the Acquisition Date occurs unless
the Special Servicer, on behalf of the Trustee, has received (or has not been denied) an extension of time (an “Extension”)
by the Internal Revenue Service to sell such Foreclosed Property or an opinion of counsel to the effect that the holding by the
Trust Fund of the Foreclosed Property for an additional specified period will neither result in the imposition of taxes on “prohibited
transactions” of the Trust Fund as defined in Section 860F of the Code, nor cause the Upper-Tier REMIC or the Lower-Tier
REMIC to fail to qualify as a REMIC at any time that the Certificates are outstanding, in which event such period shall be extended
by such additional specified period, with the expenses of obtaining any such extension of time being an expense of the Trust Fund.
If the Special Servicer, on behalf of the Trustee, has received (or has not been denied) such Extension, then the Special Servicer,
acting on behalf of the Trustee hereunder, shall continue to attempt to sell the Foreclosed Property for its fair market value
for such longer period as such Extension permits (the “Extended Period”). If the Special Servicer, acting on
behalf of the Trustee, has not received such an Extension and the Special Servicer, acting on behalf of the Trustee hereunder,
is unable to sell the Foreclosed Property, within the foregoing period or if the Special Servicer, acting on behalf of the Trustee
hereunder, has received such an Extension, and the Special Servicer, acting on behalf of the Trustee hereunder, is unable to sell
the Foreclosed Property within the Extended Period, the Special Servicer shall, before the end of the above-referenced period
or the Extended Period, as the case may be, auction the Foreclosed Property to the highest bidder (which may be the Special Servicer)
in accordance with Accepted Servicing Practices.

 

(c)           Within 30 days of the sale of a Foreclosed Property, the Special Servicer shall provide to each of the Certificate Administrator
and the Trustee a statement of accounting for the Foreclosed Property, including, without limitation, (i) the date the Property
was acquired in foreclosure or by deed in lieu of foreclosure, (ii) the date of disposition of such Foreclosed Property, (iii) the
gross sale price and related selling and other expenses, (iv) accrued interest calculated from the date of acquisition to
the disposition date, and (v) such other information as the Certificate Administrator and/or Trustee may reasonably request.

 

12.3.        Prohibited Transactions and Activities. The Special Servicer, on behalf of the Trust Fund and the Companion Loan
Holders, shall not permit the sale or disposition of the Whole Loan at a time when the Whole Loan is not the subject of a breach
of a representation or is not in default or default with respect thereto is not reasonably foreseeable (except in a disposition
pursuant to (i) the bankruptcy or insolvency of the Lower-Tier REMIC

 

    -223-

     

    

 

or (ii) the termination of the Lower-Tier
REMIC in a “qualified liquidation” as defined in Section 860F(a)(4) of the Code), nor acquire any assets for either
the Lower-Tier REMIC or the Upper-Tier REMIC (other than Foreclosed Property), nor sell or dispose of any investments in
the Collection Account or Distribution Account for gain, nor receive any amount representing a fee or other compensation for services
not contemplated herein, nor accept any contributions to either the Lower-Tier REMIC or the Upper-Tier REMIC (other than
a cash contribution during the three-month period beginning on the Startup Day), unless it has received an Opinion of Counsel
(at the expense of the Person requesting it to take such action) to the effect that such disposition, acquisition, substitution
or acceptance will not (a) affect adversely the status of either the Lower-Tier REMIC or the Upper-Tier REMIC as a
REMIC, or of the Certificates as representing regular interests therein, (b) affect the distribution of interest or principal
on the Regular Certificates, (c) result in the encumbrance of the assets transferred or assigned to either the Lower-Tier
REMIC or the Upper-Tier REMIC (except pursuant to the provisions of this Agreement), or (d) cause either the Lower-Tier
REMIC or the Upper-Tier REMIC to be subject to a tax on “prohibited transactions” or “prohibited contributions”
pursuant to the REMIC Provisions.

 

12.4.       
Indemnification with Respect to Certain Taxes and Loss of REMIC Status. (a) If either the Lower-Tier REMIC or
the Upper-Tier REMIC fails to qualify as a REMIC, loses its status as a REMIC, or incurs state or local taxes, or a tax as
a result of a prohibited transaction or contribution subject to taxation under the REMIC Provisions due to the willful misconduct,
bad faith or negligent performance by the Certificate Administrator of its duties and obligations specifically set forth herein,
or by reason of the Certificate Administrator’s negligent disregard of its obligations and duties thereunder, the Certificate
Administrator shall indemnify the Trust against any and all losses, claims, damages, liabilities or expenses (“Losses”)
resulting therefrom; provided, however, that the Certificate Administrator shall not be liable for any such Losses
attributable to the action or inaction of the Servicer, the Special Servicer, the Depositor, or the Holders of the Class R
Certificates nor for any such Losses resulting from misinformation provided by the Holders of the Class R Certificates, the
Servicer, the Special Servicer, or the Depositor, on which the Certificate Administrator has relied. The foregoing shall not be
deemed to limit or restrict the rights and remedies of successor Holders of the Class R Certificates at law or in equity.

 

(b)           If either the Lower-Tier REMIC or the Upper-Tier REMIC fails to qualify as a REMIC, loses its status as a REMIC,
or incurs state or local taxes, or a tax as a result of a prohibited transaction or contribution subject to taxation under the
REMIC Provisions due to the willful misconduct, bad faith or negligent performance of the Servicer or the Special Servicer in the
performance of its duties and obligations set forth herein, or by reason of the Servicer’s or Special Servicer’s negligent
disregard of its obligations and duties thereunder, the Servicer or the Special Servicer, as the case may be, shall indemnify the
Trust against any and all losses resulting therefrom; provided, however, that the Servicer or the Special Servicer,
as the case may be, shall not be liable for any such losses attributable to the action or inaction of the Certificate Administrator,
the Depositor, the Holders of the Class R Certificates nor for any such losses resulting from misinformation provided by the
Certificate Administrator, the Depositor or the Holders of the Class R Certificates on which the Servicer or the Special Servicer,
as the case may be, has relied. The foregoing shall not be deemed to limit or restrict the rights and remedies of any successor
Holders of the Class R Certificates at law or in equity.

13.        EXCHANGE ACT REPORTING AND REGULATION AB COMPLIANCE

 

13.1.       
Intent of the Parties; Reasonableness. The parties hereto acknowledge and agree that the purpose of Article 13
of this Agreement is, among other things, to facilitate compliance by any Senior Companion Loan Depositor with the provisions of
Regulation AB and the related rules and regulations of the Commission. Except as expressly required by Sections 13.7, 13.8
and 13.9, the Depositor shall not, and no Senior Companion Loan Depositor may, exercise its rights to request delivery of
information or other performance under these provisions other than in good faith, or for purposes other than compliance with the
Act, the Exchange Act and the Sarbanes-Oxley Act. The parties hereto acknowledge that interpretations of the requirements of
Regulation AB may change over time due to interpretive guidance provided by the Commission or its staff, and agree to comply with
reasonable requests made by the Depositor, or any Senior Companion Loan Depositor, in good faith for delivery of information under
these provisions on the basis of such evolving interpretations of Regulation AB. In connection with the Natixis Commercial Mortgage
Securities Trust 2017-75B, Commercial Mortgage Pass-Through Certificates, Series 2017-75B, and any Senior Companion Loan Securities,
each of the parties to this Agreement shall cooperate fully with the Depositor, the Certificate Administrator, any Senior Companion
Loan Depositor and any Senior Companion Loan Exchange Act Reporting Party, as applicable, to deliver to the Depositor or Senior
Companion Loan Depositor, 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 available to it and necessary in the reasonable good faith determination
of the Depositor, the Certificate Administrator, any Senior Companion Loan Depositor or any Senior Companion Loan Exchange Act
Reporting Party, as applicable, to permit any Senior Companion Loan Depositor to comply with the provisions of Regulation AB, together
with such disclosures relating to the Servicer, the Special Servicer, the Certificate Administrator and the Trustee, as applicable,
and any Sub-Servicer, or the servicing of the Whole Loan, reasonably believed by the Depositor or any Senior Companion Loan
Depositor, as applicable, in good faith to be necessary in order to effect such compliance.

 

13.2.       
Succession; Sub-Servicers; Subcontractors. (a)  For so long as any Senior Companion Loan Securitization
Trust is subject to the reporting requirements of the Exchange Act (in addition to any requirements contained in Section 13.7
of this Agreement), in connection with the succession to the Servicer and Special Servicer or any Sub-Servicer as servicer
or sub-servicer (to the extent such Sub-Servicer is a “servicer” meeting the criteria contemplated by Item
1108(a)(2) of Regulation AB) under this Agreement by any Person (i) into which the Servicer and Special Servicer or such Sub-Servicer
may be merged or consolidated, or (ii) which may be appointed as a successor to the Servicer and Special Servicer or any such
Sub-Servicer, the Servicer or Special Servicer, as applicable (depending on whether such succession involves it or one of its
Sub-Servicers), shall provide (other than in the case of a succession pursuant to an appointment under Section 7.1
or 7.2, in which case the successor servicer or successor special servicer, as applicable, shall provide) to any Senior
Companion Loan Depositor as to which the Senior Companion Loan is affected, at least five (5) Business Days prior to the effective
date of such succession or appointment as long as such disclosure prior to such effective date would not be violative of any applicable
law or confidentiality agreement (and as long as such notice is not given by a successor servicer or successor special servicer
appointed under Section 7.1 or 7.2), and otherwise no later than one (1) Business Day after such effective date
of succession,

 

    -225-

     

    

 

(x) written notice to the Depositor and each Senior Companion Loan Depositor of such succession or appointment
and (y) in writing and in form and substance reasonably satisfactory to each Senior Companion Loan Depositor, all information
relating to such successor servicer reasonably requested by any Senior Companion Loan Depositor 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).

 

(b)           For so long as any Senior Companion Loan Securitization Trust is subject to the reporting requirements of the Exchange Act,
each of the Servicer, the Special Servicer, any Sub-Servicer and the Certificate Administrator (each of the Servicer, the Special
Servicer and the Certificate Administrator and each Sub-Servicer, for purposes of this Section 13.2(b) and Section 13.2(c),
a “Servicing Party”) is permitted to utilize one or more Subcontractors to perform certain of its obligations
hereunder. Such Servicing Party shall promptly upon request provide to any Senior Companion Loan Depositor as to which the Senior
Companion Loan is affected, a written description (in form and substance satisfactory to each Senior Companion Loan Depositor)
of the role and function of each Subcontractor that is a Servicing Function Participant utilized by such Servicing Party during
the preceding calendar year, specifying (i) the identity of such Subcontractor, and (ii) which elements of the Servicing
Criteria will be addressed in assessments of compliance provided by each such Subcontractor. Each Servicing Party shall cause any
Subcontractor utilized by such Servicing Party that is determined to be a Servicing Function Participant to comply with the provisions
of Section 13.8 and Section 13.9 of this Agreement to the same extent as if such Subcontractor were such
Servicing Party. Such Servicing Party shall obtain from each such Subcontractor (or, in the case of each Sub-Servicer set forth
on Exhibit W, shall use commercially reasonable efforts to obtain from such Sub-Servicer) 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 13.8 and Section 13.9 of this Agreement, in each case, as and when required to be delivered.

 

(c)           For so long as any Senior Companion Loan Securitization Trust is subject to the reporting requirements of the Exchange Act,
notwithstanding the foregoing, if a Servicing Party engages a Subcontractor in connection with the performance of any of its duties
under this Agreement, such Servicing Party shall be responsible for determining whether such Subcontractor is a “servicer”
within the meaning of Item 1101 of Regulation AB and whether such Subcontractor meets the criteria in Item 1108(a)(2)(i), (ii) or
(iii) of Regulation AB. If a Servicing Party 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, and the engagement of such
Sub-Servicer shall not be effective unless and until notice is given to the Depositor and the Certificate Administrator, as
well as any Senior Companion Loan Depositor as to which the applicable Senior Companion Loan is affected, of any such Sub-Servicer
and Subservicing Agreement. No Subservicing Agreement (other than such agreements set forth on Exhibit W hereto) shall
be effective until five (5) Business Days after such written notice is received by the Depositor, the Certificate Administrator
and each such Senior Companion Loan Depositor. Such notice shall contain all information reasonably necessary, and in such form
as may be necessary, to enable each Senior Companion Loan Exchange Act Reporting Party as to which the applicable Companion Loan
is

 

    -226-

     

    

 

affected, to accurately and timely report the event under Item 6.02 of Form 8-K pursuant to the related Senior Companion
Loan Pooling and Servicing Agreement or otherwise (if such reports under the Exchange Act are required to be filed under the Exchange
Act).

 

(d)           For so long as any Senior Companion Loan Securitization Trust is subject to the reporting requirements of the Exchange Act,
in connection with the succession to the Trustee or Certificate Administrator under this Agreement by any Person (i) into
which the Trustee or Certificate Administrator may be merged or consolidated, or (ii) which may be appointed as a successor
to the Trustee or Certificate Administrator, the Trustee or Certificate Administrator, as applicable, shall notify the Depositor
and each Companion Loan Depositor, at least ten (10) Business Days prior to the effective date of such succession or appointment
(or if such prior notice would be violative of applicable law or any applicable confidentiality agreement, no later than the time
required under Section 13.6 of this Agreement) and shall furnish pursuant to Section 13.6 of this Agreement
to each Senior Companion Loan Depositor in writing and in form and substance reasonably satisfactory to the Depositor and each
Senior Companion Loan Depositor, all information reasonably necessary for each Senior Companion Loan Exchange Act Reporting Party
to accurately and timely report the event under Item 6.02 of Form 8-K pursuant to the related Senior Companion Loan Pooling
and Servicing Agreement or otherwise (if such reports under the Exchange Act are required to be filed under the Exchange Act).

 

13.3.        Senior Companion Loan Securitization Trust’s Filing Obligations. For so long as any Senior Companion Loan Securitization
Trust is subject to the reporting requirements of the Exchange Act, the Servicer, the Special Servicer, the Certificate Administrator
and the Trustee shall (and shall cause (or, in the case of each Sub-Servicer set forth on Exhibit W, shall use
commercially reasonable efforts to cause) each Additional Servicer and Servicing Function Participant utilized thereby to) reasonably
cooperate with each Senior Companion Loan Depositor in connection with the satisfaction of each Senior Companion Loan Securitization
Trust’s reporting requirements under the Exchange Act.

The Certificate Administrator has no duty under this Agreement to monitor or enforce the performance by the parties listed on Exhibit S

This Certificate is issued
pursuant to, and in accordance with, the terms of a Trust and Servicing Agreement, dated as of May 1, 2017 (the “Trust
and Servicing Agreement”), by and among Natixis Commercial Mortgage Securities LLC, as Depositor, KeyBank National Association,

terms used herein shall have the meanings assigned thereto in the Trust and Servicing Agreement. 

Pursuant to the terms of the Trust and Servicing
Agreement, the Certificate Administrator will distribute, on the 4th Business Day after each Determination Date, commencing in
June 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered
as of the related Record Date, which will be the close of business on the last day of the calendar month preceding the month in
which such Distribution Date occurs or, if such last day is not a Business Day, the Business Day immediately preceding such 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 and any Yield Maintenance Premiums then distributable, if any,
allocable to the Class A Certificates for such Distribution Date, all as more fully described in the Trust and Servicing Agreement. 

All distributions will be made to the Persons entitled
thereto by check mailed by first class mail to the address set forth therefor in the Certificate Register or, provided that such
Certificateholder shall have provided the Certificate Administrator with a written request for payment by wire transfer, together
with wire instructions, at least five Business Days prior to the related Distribution Date, by wire transfer of immediately available
funds to the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor. The final distribution on each Certificate shall be made in like manner, but only upon presentment and surrender of
such Certificate at the location that is specified in the notice to Certificateholders of such final distribution. 

This Certificate does not purport to summarize the
Trust and Servicing Agreement, and reference is made to the Trust 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. 

As provided in the Trust and Servicing Agreement,
subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate,
the Certificate Registrar 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 Certificate Administrator, the Trustee, the Servicer, the Special Servicer, the Certificate Registrar,
and any agent of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer 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 Trust and Servicing Agreement and for all other purposes whatsoever, and neither the Certificate Administrator,
the Trustee, the Servicer, the Special Servicer, the Certificate Registrar, nor any agent of the Certificate Administrator, the
Trustee, the Servicer, the Special Servicer or the Certificate Registrar shall be affected by any notice to the contrary. 

The Trust and Servicing Agreement may be amended
from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate Administrator and the Trustee, 

     Exhibit A-1-4

     

    

 

without the consent of any
of the Certificateholders or the Companion Loan Holders, in certain circumstances specified in the Trust and Servicing Agreement,
subject to certain exceptions set forth in the Trust and Servicing Agreement. The Trust and Servicing Agreement may also be amended
from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate Administrator and the Trustee with the
written consent of the holders of Certificates of each Class affected by such amendment (including, for the avoidance of doubt,
any Holder of an RR Interest) evidencing, in each case, not less than 51% of the aggregate Percentage Interests constituting the
Class and any Companion Loan Holder if materially and adversely affected, for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of the Trust and Servicing Agreement or of modifying in any manner the rights
of the holders of the Certificates; provided, however, that certain specified amendments require the consent of
the holders of all Certificates representing all of the Percentage Interests of the Class or Classes adversely affected thereby
and the consent of any affected Companion Loan Holder. Notwithstanding the foregoing, no amendment to the Trust and Servicing
Agreement may be made that changes in any manner the obligations of the Loan Seller under the Trust and Servicing Agreement or
under the Loan Purchase Agreement without the consent of the Loan Seller, the rights of any Initial Purchaser under the Trust
and Servicing Agreement without the written consent of such Initial Purchaser, or that adversely affects the rights and/or obligations,
if any, of a Companion Loan Holder under the Trust and Servicing Agreement without the consent of such Companion Loan Holder,
and the Certificate Administrator or Trustee may, but will not be obligated to, enter into any amendment to the Trust and Servicing
Agreement that it determines affects its rights, duties or immunities or creates any additional liability for the Certificate
Administrator or Trustee under the Trust and Servicing Agreement. In addition, no amendment may be made to the Trust and Servicing
Agreement unless the Certificate Administrator, the Trustee, the Servicer and the Special Servicer have first received an Opinion
of Counsel (at the expense of the requesting party, if applicable, and otherwise or if at the Trustee’s or the Certificate
Administrator’s request, then at the Trust Fund’s expense) to the effect that the amendment is authorized or permitted
under the Trust and Servicing Agreement and all conditions precedent have been met and that the amendment or the exercise of any
power granted to the Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator or any other specified
person in accordance with the amendment, will not result in the imposition of any tax on any portion of the Trust or cause either
the Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a
grantor trust under the Code.

 

The Trust and Servicing
Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer, the Depositor,
the Certificate Administrator and the Trustee created thereby with respect to the Certificates (other than (i) the obligation
to make certain payments to the Senior Companion Loan Holders, (ii) the obligation of the Certificate Administrator to make certain
payments to Certificateholders after the final Distribution Date and (iii) the indemnification obligations of the parties thereto)
shall terminate upon the last action required to be taken by the Certificate Administrator on the final Distribution Date pursuant
to Article 10 of the Trust and Servicing Agreement following the later of (i) the final payment on the Certificates or (ii) the
liquidation of the Trust Loan or the liquidation or abandonment of the Property and all other Collateral for the Whole Loan; provided,
however, that in no event shall the Trust continue beyond the expiration of 21 years from the death of the

     Exhibit A-1-5

     

    

 

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. 

By its acceptance of a Certificate, each Certificateholder
acknowledges and agrees that the Directing Holder, the Holders of the Certificates in the Controlling Class and the Risk Retention
Consultation Party (i) may each have special relationships and interests that conflict with those of Certificateholders of one
or more Classes of the Certificates, including owning any interest in the Mezzanine Loan, (ii) may act solely in its own interests
or in the interests of the holders of the Controlling Class or the RR Interest, (iii) do not have any duties or liability to the
Issuing Entity or to the Holders of any Class of Certificates, (iv) may take actions that favor the interests of the Companion
Loans or the interests of one or more Classes of the Certificates or the RR Interest over other Classes of the Certificates, (v)
shall have no liability whatsoever to the Trust, the other parties hereto, the Certificateholders or any other person (including
any Borrower Affiliate) for having acted in accordance with or as permitted under the terms of this Agreement, and the Certificateholders
may not take any action whatsoever against the Directing Holder, the holders of the Certificates in the Controlling Class, the
Risk Retention Consultation Party or any of the respective affiliates, directors, officers, shareholders, members, partners, agents
or principals of the Directing Holder, the holders of the Certificates in the Controlling Class or the Risk Retention Consultation
Party as a result of the Directing Holder, the holders of the Certificates in the Controlling Class or the Risk Retention Consultation
Party having acted in accordance with the terms of and as permitted under the Trust and Servicing Agreement. 

Unless the Certificate
of Authentication on this Certificate has been executed by the Certificate Administrator or on its behalf by the Authenticating
Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Trust and Servicing Agreement or be

Pursuant to the terms of the Trust and Servicing
Agreement, the Certificate Administrator will distribute, on the 4th Business Day after each Determination Date, commencing in
June 2017 (each such date, a “Distribution Date”), to the Person in whose name this Certificate is registered

of that portion of the aggregate amount of principal and interest and any Yield Maintenance Premiums then distributable, if any,
allocable to the Class B Certificates for such Distribution Date, all as more fully described in the Trust and Servicing Agreement. 

All distributions will be made to the Persons entitled
thereto by check mailed by first class mail to the address set forth therefor in the Certificate Register or, provided that such
Certificateholder shall have provided the Certificate Administrator with a written request for payment by wire transfer, together
with wire instructions, at least five Business Days prior to the related Distribution Date, by wire transfer of immediately available
funds to the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor. The final distribution on each Certificate shall be made in like manner, but only upon presentment and surrender of
such Certificate at the location that is specified in the notice to Certificateholders of such final distribution. 

This Certificate does not purport to summarize the
Trust and Servicing Agreement, and reference is made to the Trust 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. 

As provided in the Trust and Servicing Agreement,
subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer of any Certificate,
the Certificate Registrar 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 Certificate Administrator, the Trustee, the Servicer, the Special Servicer, the Certificate Registrar,
and any agent of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer 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 Trust and Servicing Agreement and for all other purposes whatsoever, and neither the Certificate Administrator,
the Trustee, the Servicer, the Special Servicer, the Certificate Registrar, nor any agent of the Certificate Administrator, the
Trustee, the Servicer, the Special Servicer or the Certificate Registrar shall be affected by any notice to the contrary. 

The
Trust and Servicing Agreement may be amended from time to time by the Depositor, the Servicer, the Special Servicer, the
Certificate Administrator and the Trustee,

 

     Exhibit A-2-5

     

    

 

without

may also be amended from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate Administrator and
the Trustee with the written consent of the holders of Certificates of each Class affected by such amendment (including, for the
avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not less than 51% of the aggregate Percentage Interests
constituting the Class and any Companion Loan Holder if materially and adversely affected, for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of the Trust and Servicing Agreement or of modifying in any
manner the rights of the holders of the Certificates; provided, however, that certain specified amendments require the
consent of the holders of all Certificates representing all of the Percentage Interests of the Class or Classes adversely affected
thereby and the consent of any affected Companion Loan Holder. Notwithstanding the foregoing, no amendment to the Trust and Servicing
Agreement may be made that changes in any manner the obligations of the Loan Seller under the Trust and Servicing Agreement or
under the Loan Purchase Agreement without the consent of the Loan Seller, the rights of any Initial Purchaser under the Trust
and Servicing Agreement without the written consent of such Initial Purchaser, or that adversely affects the rights and/or obligations,
if any, of a Companion Loan Holder under the Trust and Servicing Agreement without the consent of such Companion Loan Holder,
and the Certificate Administrator or Trustee may, but will not be obligated to, enter into any amendment to the Trust and Servicing
Agreement that it determines affects its rights, duties or immunities or creates any additional liability for the Certificate
Administrator or Trustee under the Trust and Servicing Agreement. In addition, no amendment may be made to the Trust and Servicing
Agreement unless the Certificate Administrator, the Trustee, the Servicer and the Special Servicer have first received an Opinion
of Counsel (at the expense of the requesting party, if applicable, and otherwise or if at the Trustee’s or the Certificate
Administrator’s request, then at the Trust Fund’s expense) to the effect that the amendment is authorized or permitted
under the Trust and Servicing Agreement and all conditions precedent have been met and that the amendment or the exercise of any
power granted to the Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator or any other specified
person in accordance with the amendment, will not result in the imposition of any tax on any portion of the Trust or cause either
the Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a
grantor trust under the Code.

 

The Trust and Servicing
Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer, the Depositor, the
Certificate Administrator and the Trustee created thereby with respect to the Certificates (other than (i) the obligation to make
certain payments to the Senior Companion Loan Holders, (ii) the obligation of the Certificate Administrator to make certain payments
to Certificateholders after the final Distribution Date and (iii) the indemnification obligations of the parties thereto) shall

of the Trust Loan or the liquidation or abandonment of the Property and all other Collateral for the Whole Loan; provided, however,

shall have no liability whatsoever to the Trust, the other parties hereto, the Certificateholders or any other person (including
any Borrower Affiliate) for having acted in accordance with or as permitted under the terms of this Agreement, and the Certificateholders
may not take any action whatsoever against the Directing Holder, the holders of the Certificates in the Controlling Class, the
Risk Retention Consultation Party or any of the respective affiliates, directors, officers, shareholders, members, partners, agents
or principals of the Directing Holder, the holders of the Certificates in the Controlling Class or the Risk Retention Consultation

if applicable, and otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s
expense) to the effect that the amendment is authorized or permitted under the Trust and Servicing Agreement and all conditions

This
certifies that [Cede & Co.] [[____], in its capacity as Retaining Party in satisfaction of Regulation RR] is the registered
owner of the Percentage Interest evidenced by this Certificate in the distributions to be made from a Trust Fund with respect
to the Class D Certificates. The Trust Fund consists primarily of two promissory notes secured by the Collateral held in trust
by the Trustee issued by a special purpose entity evidencing a fixed rate loan (the “Trust Loan”). The Trust
Fund was created, and the Trust Loan is to be serviced, pursuant to the Trust 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 Trust and
Servicing Agreement and is bound thereby. Also issued under the Trust and Servicing Agreement are the Class A, Class X-A, Class
X-B, Class B, Class C, Class E, Class V1-A, Class V1-XB, Class V1-B, Class V1-C, Class V1-D, Class V1-E, Class V2 and Class R
Certificates (collectively with the Class D Certificates, the “Certificates”; the holders of Certificates issued
under the Trust and Servicing Agreement are collectively referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Trust and Servicing Agreement, dated as of May 1, 2017
(the “Trust and Servicing Agreement”), by and among Natixis Commercial Mortgage Securities LLC, as Depositor,
KeyBank National Association, as Servicer and Special Servicer and Wells Fargo Bank, National Association, as Trustee, Certificate

    Exhibit A-4-4

     

    

 

terms
used herein shall have the meanings assigned thereto in the Trust and Servicing Agreement.

 

Pursuant
to the terms of the Trust and Servicing Agreement, the Certificate Administrator will distribute, on the 4th Business Day after
each Determination Date, commencing in June 2017 (each such date, a “Distribution Date”), to the Person in
whose name this Certificate is registered as of the related Record Date, which will be the close of business on the last day of
the calendar month preceding the month in which such Distribution Date occurs or, if such last day is not a Business Day, the
Business Day immediately preceding such 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 and any Yield Maintenance Premiums
then distributable, if any, allocable to the Class D Certificates for such Distribution Date, all as more fully described in the
Trust and Servicing Agreement.

 

All
distributions will be made to the Persons entitled thereto by check mailed by first class mail to the address set forth therefor
in the Certificate Register or, provided that such Certificateholder shall have provided the Certificate Administrator with a
written request for payment by wire transfer, together with wire instructions, at least five Business Days prior to the related
Distribution Date, by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other
entity located in the United States and having appropriate facilities therefor. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the location that is specified in the notice
to Certificateholders of such final distribution.

 

This
Certificate does not purport to summarize the Trust and Servicing Agreement, and reference is made to the Trust 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.

 

As
provided in the Trust and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for
registration of transfer of any Certificate, the Certificate Registrar 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 Certificate Administrator, the Trustee, the Servicer,
the Special Servicer, the Certificate Registrar, and any agent of the Certificate Administrator, the Trustee, the Servicer, the
Special Servicer 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 Trust and Servicing Agreement and for all other
purposes whatsoever, and neither the Certificate Administrator, the Trustee, the Servicer, the Special Servicer, the Certificate
Registrar, nor any agent of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer or the Certificate
Registrar shall be affected by any notice to the contrary.

 

The Trust and Servicing Agreement may be amended from time to time by
the Depositor, the Servicer, the Special Servicer, the Certificate Administrator and the Trustee,

 

    Exhibit A-4-5

     

    

 

without
the consent of any of the Certificateholders or the Companion Loan Holders, in certain circumstances specified in the Trust and
Servicing Agreement, subject to certain exceptions set forth in the Trust and Servicing Agreement. The Trust and Servicing Agreement
may also be amended from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate Administrator and
the Trustee with the written consent of the holders of Certificates of each Class affected by such amendment (including, for the
avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not less than 51% of the aggregate Percentage Interests
constituting the Class and any Companion Loan Holder if materially and adversely affected, for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of the Trust and Servicing Agreement or of modifying in any
manner the rights of the holders of the Certificates; provided, however, that certain specified amendments
require the consent of the holders of all Certificates representing all of the Percentage Interests of the Class or Classes adversely
affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the foregoing, no amendment to the Trust
and Servicing Agreement may be made that changes in any manner the obligations of the Loan Seller under the Trust and Servicing
Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the rights of any Initial Purchaser under
the Trust and Servicing Agreement without the written consent of such Initial Purchaser, or that adversely affects the rights
and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement without the consent of such Companion
Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated to, enter into any amendment to the Trust
and Servicing Agreement that it determines affects its rights, duties or immunities or creates any additional liability for the
Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition, no amendment may be made to the Trust
and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer and the Special Servicer have first received
an Opinion of Counsel (at the expense of the requesting party, if applicable, and otherwise or if at the Trustee’s or the
Certificate Administrator’s request, then at the Trust Fund’s expense) to the effect that the amendment is authorized
or permitted under the Trust and Servicing Agreement and all conditions precedent have been met and that the amendment or the
exercise of any power granted to the Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator
or any other specified person in accordance with the amendment, will not result in the imposition of any tax on any portion of
the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify as a REMIC or cause the Grantor Trust
to fail to qualify as a grantor trust under the Code.

 

The
Trust and Servicing Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer,
the Depositor, the Certificate Administrator and the Trustee created thereby with respect to the Certificates (other than (i)
the obligation to make certain payments to the Senior Companion Loan Holders, (ii) the obligation of the Certificate Administrator
to make certain payments to Certificateholders after the final Distribution Date and (iii) the indemnification obligations of
the parties thereto) shall terminate upon the last action required to be taken by the Certificate Administrator on the final Distribution
Date pursuant to Article 10 of the Trust and Servicing Agreement following the later of (i) the final payment on the Certificates
or (ii) the liquidation of the Trust Loan or the liquidation or abandonment of the Property and all other Collateral for the Whole
Loan; provided, however, that in no event shall the Trust continue beyond the expiration of 21 years from the
death of the

 

    Exhibit A-4-6

     

    

 

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.

 

By
its acceptance of a Certificate, each Certificateholder acknowledges and agrees that the Directing Holder, the Holders of the
Certificates in the Controlling Class and the Risk Retention Consultation Party (i) may each have special relationships and interests
that conflict with those of Certificateholders of one or more Classes of the Certificates, including owning any interest in the
Mezzanine Loan, (ii) may act solely in its own interests or in the interests of the holders of the Controlling Class or the RR
Interest, (iii) do not have any duties or liability to the Issuing Entity or to the Holders of any Class of Certificates, (iv)
may take actions that favor the interests of the Companion Loans or the interests of one or more Classes of the Certificates or
the RR Interest over other Classes of the Certificates, (v) shall have no liability whatsoever to the Trust, the other parties
hereto, the Certificateholders or any other person (including any Borrower Affiliate) for having acted in accordance with or as
permitted under the terms of this Agreement, and the Certificateholders may not take any action whatsoever against the Directing
Holder, the holders of the Certificates in the Controlling Class, the Risk Retention Consultation Party or any of the respective
affiliates, directors, officers, shareholders, members, partners, agents or principals of the Directing Holder, the holders of
the Certificates in the Controlling Class or the Risk Retention Consultation Party as a result of the Directing Holder, the holders
of the Certificates in the Controlling Class or the Risk Retention Consultation Party having acted in accordance with the terms
of and as permitted under the Trust and Servicing Agreement.

 

Unless
the Certificate of Authentication on this Certificate has been executed by the Certificate Administrator or on its behalf by the
Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Trust and Servicing
Agreement or be valid for any purpose.

 

The

sufficiency of the Certificates or the Trust Loan and has executed this Certificate in its limited capacity as Certificate Administrator
under the Trust and Servicing Agreement.

terms
used herein shall have the meanings assigned thereto in the Trust and Servicing Agreement.

 

Pursuant
to the terms of the Trust and Servicing Agreement, the Certificate Administrator will distribute, on the 4th Business Day after
each Determination Date, commencing in June 2017 (each such date, a “Distribution Date”), to the Person in
whose name this Certificate is registered as of the related Record Date, which will be the close of business on the last day of
the calendar month preceding the month in which such Distribution Date occurs or, if such last day is not a Business Day, the
Business Day immediately preceding such 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 and any Yield Maintenance Premiums
then distributable, if any, allocable to the Class E Certificates for such Distribution Date, all as more fully described in the
Trust and Servicing Agreement.

 

All
distributions will be made to the Persons entitled thereto by check mailed by first class mail to the address set forth therefor
in the Certificate Register or, provided that such Certificateholder shall have provided the Certificate Administrator with a
written request for payment by wire transfer, together with wire instructions, at least five Business Days prior to the related
Distribution Date, by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other
entity located in the United States and having appropriate facilities therefor. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the location that is specified in the notice
to Certificateholders of such final distribution.

 

This
Certificate does not purport to summarize the Trust and Servicing Agreement, and reference is made to the Trust 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.

 

As
provided in the Trust and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for
registration of transfer of any Certificate, the Certificate Registrar 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 Certificate Administrator, the Trustee, the Servicer,
the Special Servicer, the Certificate Registrar, and any agent of the Certificate Administrator, the Trustee, the Servicer, the
Special Servicer 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 Trust and Servicing Agreement and for all other
purposes whatsoever, and neither the Certificate Administrator, the Trustee, the Servicer, the Special Servicer, the Certificate
Registrar, nor any agent of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer or the Certificate
Registrar shall be affected by any notice to the contrary.

 

The Trust and Servicing Agreement may be amended from time to time by
the Depositor, the Servicer, the Special Servicer, the Certificate Administrator and the Trustee,

 

    Exhibit A-5-5

     

    

 

without
the consent of any of the Certificateholders or the Companion Loan Holders, in certain circumstances specified in the Trust and
Servicing Agreement, subject to certain exceptions set forth in the Trust and Servicing Agreement. The Trust and Servicing Agreement
may also be amended from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate Administrator and
the Trustee with the written consent of the holders of Certificates of each Class affected by such amendment (including, for the
avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not less than 51% of the aggregate Percentage Interests
constituting the Class and any Companion Loan Holder if materially and adversely affected, for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of the Trust and Servicing Agreement or of modifying in any
manner the rights of the holders of the Certificates; provided, however, that certain specified amendments
require the consent of the holders of all Certificates representing all of the Percentage Interests of the Class or Classes adversely
affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the foregoing, no amendment to the Trust
and Servicing Agreement may be made that changes in any manner the obligations of the Loan Seller under the Trust and Servicing
Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the rights of any Initial Purchaser under
the Trust and Servicing Agreement without the written consent of such Initial Purchaser, or that adversely affects the rights
and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement without the consent of such Companion
Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated to, enter into any amendment to the Trust
and Servicing Agreement that it determines affects its rights, duties or immunities or creates any additional liability for the
Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition, no amendment may be made to the Trust
and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer and the Special Servicer have first received
an Opinion of Counsel (at the expense of the requesting party, if applicable, and otherwise or if at the Trustee’s or the
Certificate Administrator’s request, then at the Trust Fund’s expense) to the effect that the amendment is authorized
or permitted under the Trust and Servicing Agreement and all conditions precedent have been met and that the amendment or the
exercise of any power granted to the Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator
or any other specified person in accordance with the amendment, will not result in the imposition of any tax on any portion of
the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to qualify as a REMIC or cause the Grantor Trust
to fail to qualify as a grantor trust under the Code.

 

The
Trust and Servicing Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer,
the Depositor, the Certificate Administrator and the Trustee created thereby with respect to the Certificates (other than (i)
the obligation to make certain payments to the Senior Companion Loan Holders, (ii) the obligation of the Certificate Administrator
to make certain payments to Certificateholders after the final Distribution Date and (iii) the indemnification obligations of
the parties thereto) shall terminate upon the last action required to be taken by the Certificate Administrator on the final Distribution
Date pursuant to Article 10 of the Trust and Servicing Agreement following the later of (i) the final payment on the Certificates
or (ii) the liquidation of the Trust Loan or the liquidation or abandonment of the Property and all other Collateral for the Whole
Loan; provided, however, that in no event shall the Trust continue beyond the expiration of 21 years from the
death of the

 

    Exhibit A-5-6

     

    

 

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.

 

By
its acceptance of a Certificate, each Certificateholder acknowledges and agrees that the Directing Holder, the Holders of the
Certificates in the Controlling Class and the Risk Retention Consultation Party (i) may each have special relationships and interests
that conflict with those of Certificateholders of one or more Classes of the Certificates, including owning any interest in the
Mezzanine Loan, (ii) may act solely in its own interests or in the interests of the holders of the Controlling Class or the RR
Interest, (iii) do not have any duties or liability to the Issuing Entity or to the Holders of any Class of Certificates, (iv)
may take actions that favor the interests of the Companion Loans or the interests of one or more Classes of the Certificates or
the RR Interest over other Classes of the Certificates, (v) shall have no liability whatsoever to the Trust, the other parties
hereto, the Certificateholders or any other person (including any Borrower Affiliate) for having acted in accordance with or as
permitted under the terms of this Agreement, and the Certificateholders may not take any action whatsoever against the Directing
Holder, the holders of the Certificates in the Controlling Class, the Risk Retention Consultation Party or any of the respective
affiliates, directors, officers, shareholders, members, partners, agents or principals of the Directing Holder, the holders of
the Certificates in the Controlling Class or the Risk Retention Consultation Party as a result of the Directing Holder, the holders
of the Certificates in the Controlling Class or the Risk Retention Consultation Party having acted in accordance with the terms
of and as permitted under the Trust and Servicing Agreement.

such Certificate for the purpose of receiving distributions as provided in the Trust and Servicing Agreement and for all other
purposes whatsoever, and neither the Certificate Administrator, the Trustee, the Servicer, the Special Servicer, the Certificate
Registrar, nor any agent of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer or the Certificate
Registrar shall be affected by any notice to the contrary.

 

The
Trust and Servicing Agreement may be amended from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate
Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Loan Holders, in certain
circumstances specified in the Trust and Servicing Agreement, subject to certain exceptions set forth in the Trust and Servicing
Agreement. The Trust and Servicing Agreement may also be amended from time to time by the Depositor, the Servicer, the Special
Servicer, the Certificate Administrator and the Trustee with the written consent of the holders of Certificates of each Class
affected by such amendment (including, for the avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not
less than 51% of the aggregate Percentage Interests constituting the Class and any Companion Loan Holder if materially and adversely
affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Trust
and Servicing Agreement or of modifying in any manner the rights of the holders of the Certificates; provided, however,
that certain specified amendments require the consent of the holders of all Certificates representing all of the Percentage Interests
of the Class or Classes adversely affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the
foregoing, no amendment to the Trust and Servicing Agreement may be made that changes in any manner the obligations of the Loan
Seller under the Trust and Servicing Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the
rights of any Initial Purchaser under the Trust and Servicing Agreement without the written consent of such Initial Purchaser,
or that adversely affects the rights and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement
without the consent of such Companion Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated
to, enter into any amendment to the Trust and Servicing Agreement that it determines affects its rights, duties or immunities
or creates any additional liability for the Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition,
no amendment may be made to the Trust and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer
and the Special Servicer have first received an Opinion of Counsel (at the expense of the requesting party, if applicable, and
otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)
to the effect that the amendment is authorized or permitted under the Trust and Servicing Agreement and all conditions precedent
have been met and that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator or any other specified person in accordance with the amendment, will not result in
the imposition of any tax on any portion of the Trust or cause either the Lower-Tier REMIC or

 

    Exhibit A-6-6

     

    

 

the
Upper-Tier REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the Code.

 

The
Trust and Servicing Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer,
the Depositor, the Certificate Administrator and the Trustee created thereby with respect to the Certificates (other than (i)
the obligation to make certain payments to the Senior Companion Loan Holders, (ii) the obligation of the Certificate Administrator
to make certain payments to Certificateholders after the final Distribution Date and (iii) the indemnification obligations of
the parties thereto) shall terminate upon the last action required to be taken by the Certificate Administrator on the final Distribution
Date pursuant to Article 10 of the Trust and Servicing Agreement following the later of (i) the final payment on the Certificates
or (ii) the liquidation of the Trust Loan or the liquidation or abandonment of the Property and all other Collateral for the Whole
Loan; provided, however, that in no event shall the Trust 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’s,
living on the date hereof.

 

By
its acceptance of a Certificate, each Certificateholder acknowledges and agrees that the Directing Holder, the Holders of the
Certificates in the Controlling Class and the Risk Retention Consultation Party (i) may each have special relationships and interests
that conflict with those of Certificateholders of one or more Classes of the Certificates, including owning any interest in the
Mezzanine Loan, (ii) may act solely in its own interests or in the interests of the holders of the Controlling Class or the RR
Interest, (iii) do not have any duties or liability to the Issuing Entity or to the Holders of any Class of Certificates, (iv)
may take actions that favor the interests of the Companion Loans or the interests of one or more Classes of the Certificates or
the RR Interest over other Classes of the Certificates, (v) shall have no liability whatsoever to the Trust, the other parties
hereto, the Certificateholders or any other person (including any Borrower Affiliate) for having acted in accordance with or as
permitted under the terms of this Agreement, and the Certificateholders may not take any action whatsoever against the Directing
Holder, the holders of the Certificates in the Controlling Class, the Risk Retention Consultation Party or any of the respective
affiliates, directors, officers, shareholders, members, partners, agents or principals of the Directing Holder, the holders of
the Certificates in the Controlling Class or the Risk Retention Consultation Party as a result of the Directing Holder, the holders
of the Certificates in the Controlling Class or the Risk Retention Consultation Party having acted in accordance with the terms

To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Trust and Servicing
Agreement.

 

Pursuant
to the terms of the Trust and Servicing Agreement, the Certificate Administrator will distribute, on the 4th Business Day after
each Determination Date, commencing in June 2017 (each such date, a “Distribution Date”), to the Person in
whose name this Certificate is registered as of the related Record Date, which will be the close of business on the last day of
the calendar month preceding the month in which such Distribution Date occurs or, if such last day is not a Business Day, the
Business Day immediately preceding such 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 and any Yield Maintenance Premiums
then distributable, if any, allocable to the Class X-B Certificates for such Distribution Date, all as more fully described in
the Trust and Servicing Agreement.

 

All
distributions will be made to the Persons entitled thereto by check mailed by first class mail to the address set forth therefor
in the Certificate Register or, provided that such Certificateholder shall have provided the Certificate Administrator with a
written request for payment by wire transfer, together with wire instructions, at least five Business Days prior to the related
Distribution Date, by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other
entity located in the United States and having appropriate facilities therefor. The final distribution on each Certificate shall

to Certificateholders of such final distribution.

 

During
each Certificate Interest Accrual Period (as defined below), interest on the Class X-B Certificates will be calculated based on
a 360-day year consisting of twelve 30-day months on the outstanding Notional Balance hereof.

 

Interest
accrued on this Certificate during a Certificate 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 Trust and Servicing
Agreement. The “Certificate Interest Accrual Period” means, with respect to any Distribution Date, the period from

to and including the fourth day of the calendar month in which such Distribution Date occurs.

 

This
Certificate does not purport to summarize the Trust and Servicing Agreement, and reference is made to the Trust 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.

 

As

registration of transfer of any Certificate, the Certificate Registrar shall execute, authenticate and deliver, in the name of
the designated

Agreement. The Trust and Servicing Agreement may also be amended from time to time by the Depositor, the Servicer, the Special
Servicer, the Certificate Administrator and the Trustee with the written consent of the holders of Certificates of each Class
affected by such amendment (including, for the avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not

affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Trust
and Servicing Agreement or of modifying in any manner the rights of the holders of the Certificates; provided, however, that certain specified amendments require the consent of the holders of all Certificates representing all of the Percentage Interests
of the Class or Classes adversely affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the
foregoing, no amendment to the Trust and Servicing Agreement may be made that changes in any manner the obligations of the Loan
Seller under the Trust and Servicing Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the
rights of any Initial Purchaser under the Trust and Servicing Agreement without the written consent of such Initial Purchaser,
or that adversely affects the rights and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement
without the consent of such Companion Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated
to, enter into any amendment to the Trust and Servicing Agreement that it determines affects its rights, duties or immunities
or creates any additional liability for the Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition,
no amendment may be made to the Trust and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer

otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)

have been met and that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor,

This

to be made from a Trust Fund with respect to the Class R Certificates. The Trust Fund consists primarily of two promissory notes
secured by a partial interest in the Collateral held in trust by the Trustee issued by a special purpose entity evidencing a fixed
rate loan (the “Trust Loan”). The Trust Fund was created, and the Trust Loan is to be serviced, pursuant to
the Trust 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 Trust and Servicing Agreement and is bound thereby. Also issued under the Trust
and Servicing Agreement are the Class A, Class X-A, Class X-B, Class B, Class C, Class D, Class E, Class V1-A, Class V1-XB, Class
V1-B, Class V1-C, Class V1-D, Class V1-E and Class V2 Certificates (collectively with the Class R Certificates, the “Certificates”;
the holders of Certificates issued under the Trust and Servicing Agreement are collectively referred to herein as “Certificateholders”).

 

This Certificate
is issued pursuant to, and in accordance with, the terms of a Trust and Servicing Agreement, dated as of May 1, 2017 (the “Trust
and Servicing Agreement”), by and among Natixis Commercial Mortgage Securities LLC, as Depositor, KeyBank National Association,
as Servicer and Special Servicer and Wells Fargo Bank, National Association, as Trustee, Certificate Administrator and Custodian.
To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Trust and Servicing
Agreement.

    Exhibit A-8-4

     

    

 

This Class R Certificate
represents the sole “residual interest” in two “real estate mortgage investment conduits”, as those terms
are defined, respectively, in Sections 860G(a)(2) and 860D of the Internal Revenue Code of 1986, as amended. Each Holder of this
Certificate, by acceptance hereof, agrees to treat, and take no action inconsistent with the treatment of, this Certificate in
accordance with the preceding sentence for purposes of federal income taxes, state and local income and franchise taxes and other
taxes imposed on or measured by income. The Holder of the largest Percentage Interest in the Class R Certificates shall be the
“tax matters person” pursuant to Treasury Regulations Section 1.860F-4(d) and the “partnership representative”
within the meaning of Section 6223 of the Code (to the extent such provision is applicable to such Trust REMIC) for the Upper-Tier
REMIC and the Lower-Tier REMIC, and the Certificate Administrator is hereby irrevocably designated and shall serve as attorney-in-fact
and agent for any such Person that is the “tax matters person” and/or “partnership representative” for
the Upper-Tier REMIC and the Lower-Tier REMIC.

 

This Certificate does not
purport to summarize the Trust and Servicing Agreement, and reference is made to the Trust 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 Trustee.

 

All distributions (other
than the final distribution on any Certificate) will be made by the Paying Agent 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 day of the calendar
month preceding the month in which such Distribution Date occurs or, if such last day is not a Business Day, the Business Day immediately
preceding such date. Such distributions shall be made on each Distribution Date other than the Termination Date to each Certificateholder
of record on the related Record Date, by wire transfer of immediately available funds to the account of such Holder at a bank or
other entity located in the United States and having appropriate facilities therefor provided that such Holder shall have provided
the Paying Agent with wire instructions in writing at least five Business Days prior to the related Record Date, or, otherwise,
by check mailed by first-class mail to the address set forth therefor in the Certificate Register. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Holders of such final distribution.

 

As provided in the Trust
and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer
of any Certificate, the Certificate Registrar 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 Certificate Administrator, the Trustee, the Servicer, the Special Servicer,
the Certificate Registrar, and any agent of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer 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 Trust and Servicing Agreement and for all other purposes whatsoever, and
neither the

 

    Exhibit A-8-5

     

    

 

Certificate Administrator, the Trustee,
the Servicer, the Special Servicer, the Certificate Registrar, nor any agent of the Certificate Administrator, the Trustee, the
Servicer, the Special Servicer or the Certificate Registrar shall be affected by any notice to the contrary.

 

The Trust
and Servicing Agreement may be amended from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate
Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Loan Holders, in certain
circumstances specified in the Trust and Servicing Agreement, subject to certain exceptions set forth in the Trust and Servicing
Agreement. The Trust and Servicing Agreement may also be amended from time to time by the Depositor, the Servicer, the Special
Servicer, the Certificate Administrator and the Trustee with the written consent of the holders of Certificates of each Class
affected by such amendment (including, for the avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not
less than 51% of the aggregate Percentage Interests constituting the Class and any Companion Loan Holder if materially and adversely
affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Trust
and Servicing Agreement or of modifying in any manner the rights of the holders of the Certificates; provided, however,
that certain specified amendments require the consent of the holders of all Certificates representing all of the Percentage Interests
of the Class or Classes adversely affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the
foregoing, no amendment to the Trust and Servicing Agreement may be made that changes in any manner the obligations of the Loan
Seller under the Trust and Servicing Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the
rights of any Initial Purchaser under the Trust and Servicing Agreement without the written consent of such Initial Purchaser,
or that adversely affects the rights and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement
without the consent of such Companion Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated
to, enter into any amendment to the Trust and Servicing Agreement that it determines affects its rights, duties or immunities
or creates any additional liability for the Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition,
no amendment may be made to the Trust and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer
and the Special Servicer have first received an Opinion of Counsel (at the expense of the requesting party, if applicable, and
otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)
to the effect that the amendment is authorized or permitted under the Trust and Servicing Agreement and all conditions precedent
have been met and that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator or any other specified person in accordance with the amendment, will not result in
the imposition of any tax on any portion of the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to
qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the Code.

 

The Trust and Servicing
Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer, the Depositor, the
Certificate Administrator and the Trustee created thereby with respect to the Certificates (other than (i) the obligation to make
certain payments to the Senior Companion Loan Holders, (ii) the obligation of the Certificate Administrator to make certain payments
to Certificateholders after the final Distribution Date and (iii) the indemnification obligations of the parties thereto) shall
terminate

 

    Exhibit A-8-6

     

    

 

upon the last action required
to be taken by the Certificate Administrator on the final Distribution Date pursuant to Article 10 of the Trust and Servicing
Agreement following the later of (i) the final payment on the Certificates or (ii) the liquidation of the Trust Loan or the liquidation
or abandonment of the Property and all other Collateral for the Whole Loan; provided, however, that in no event
shall the Trust 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’s, living on the date hereof.

 

By its acceptance of a
Certificate, each Certificateholder acknowledges and agrees that the Directing Holder, the Holders of the Certificates in the Controlling
Class and the Risk Retention Consultation Party (i) may each have special relationships and interests that conflict with those
of Certificateholders of one or more Classes of the Certificates, including owning any interest in the Mezzanine Loan, (ii) may
act solely in its own interests or in the interests of the holders of the Controlling Class or the RR Interest, (iii) do not have
any duties or liability to the Issuing Entity or to the Holders of any Class of Certificates, (iv) may take actions that favor
the interests of the Companion Loans or the interests of one or more Classes of the Certificates or the RR Interest over other
Classes of the Certificates, (v) shall have no liability whatsoever to the Trust, the other parties hereto, the Certificateholders
or any other person (including any Borrower Affiliate) for having acted in accordance with or as permitted under the terms of this
Agreement, and the Certificateholders may not take any action whatsoever against the Directing Holder, the holders of the Certificates
in the Controlling Class, the Risk Retention Consultation Party or any of the respective affiliates, directors, officers, shareholders,
members, partners, agents or principals of the Directing Holder, the holders of the Certificates in the Controlling Class or the
Risk Retention Consultation Party as a result of the Directing Holder, the holders of the Certificates in the Controlling Class
or the Risk Retention Consultation Party having acted in accordance with the terms of and as permitted under the Trust and Servicing
Agreement.

 

Unless the Certificate
of Authentication on this Certificate has been executed by the Certificate Administrator or on its behalf by the Authenticating
Agent, by manual signature, this Certificate shall not be entitled to any benefit under the Trust and Servicing Agreement or be
valid for any purpose.

 

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

less than 51% of the aggregate Percentage Interests constituting the Class and any Companion Loan Holder if materially and adversely
affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Trust

or creates any additional liability for the Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition,
no amendment may be made to the Trust and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer

otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)
to the effect that the amendment is authorized or permitted under the Trust and Servicing Agreement and all conditions precedent
have been met and that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator or any other specified person in accordance with the amendment, will not result in
the imposition of any tax on any portion of the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to
qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the Code.

liquidation of the Trust Loan or the liquidation or abandonment of the Property and all other Collateral for the Whole Loan; provided,

the interests of the Companion Loans or the interests of one or more Classes of the Certificates or the RR Interest over other
Classes of the Certificates, (v) shall have no liability whatsoever to the Trust, the other parties hereto, the Certificateholders
or any other person (including any Borrower Affiliate) for having acted in accordance with or as permitted under the terms of this
Agreement, and the Certificateholders may not take any action whatsoever against the Directing Holder, the holders of the Certificates
in the Controlling Class, the Risk Retention Consultation Party or any of the respective affiliates, directors, officers, shareholders,
members, partners, agents or principals of the Directing Holder, the holders of the Certificates in the Controlling Class or the
Risk Retention Consultation Party as a result of the Directing Holder, the holders of the Certificates in the Controlling Class

Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Loan Holders, in certain
circumstances specified in the Trust and Servicing Agreement, subject to certain exceptions set forth in the Trust and Servicing
Agreement. The Trust and Servicing Agreement may also be amended from time to time by the Depositor, the Servicer, the Special
Servicer, the Certificate Administrator and the Trustee with the written consent of the holders of Certificates of each Class
affected by such amendment (including, for the avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not
less than 51% of the aggregate Percentage Interests constituting the Class and any Companion Loan Holder if materially and adversely
affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Trust
and Servicing Agreement or of modifying in any manner the rights of the holders of the Certificates; provided, however,
that certain specified amendments require the consent of the holders of all Certificates representing all of the Percentage Interests
of the Class or Classes adversely affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the
foregoing, no amendment to the Trust and Servicing Agreement may be made that changes in any manner the obligations of the Loan
Seller under the Trust and Servicing Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the
rights of any Initial Purchaser under the Trust and Servicing Agreement without the written consent of such Initial Purchaser,
or that adversely affects the rights and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement
without the consent of such Companion Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated
to, enter into any amendment to the Trust and Servicing Agreement that it determines affects its rights, duties or immunities
or creates any additional liability for the Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition,
no amendment may be made to the Trust and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer
and the Special Servicer have first received an Opinion of Counsel (at the expense of the requesting party, if applicable, and
otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)
to the effect that the amendment is authorized or permitted under the Trust and Servicing Agreement and all conditions precedent
have been met and that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator or any other specified person in accordance with the amendment, will not result in
the imposition of any tax on any portion of the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to
qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the Code.

 

    Exhibit A-11-6

This Certificate does not
purport to summarize the Trust and Servicing Agreement, and reference is made to the Trust 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.

 

As provided in the Trust
and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration of transfer

any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Trust
and Servicing Agreement and for all other purposes whatsoever, and neither the Certificate Administrator, the Trustee, the Servicer,
the Special Servicer, the Certificate Registrar, nor any agent of the Certificate Administrator, the Trustee, the Servicer, the
Special Servicer or the Certificate Registrar shall be affected by any notice to the contrary.

 

The Trust

Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Loan Holders, in certain
circumstances specified in the Trust and Servicing Agreement, subject to certain exceptions set forth in the Trust and Servicing
Agreement. The Trust and Servicing Agreement may also be amended from time to time by the Depositor, the Servicer, the Special
Servicer, the Certificate Administrator and the Trustee with the written consent of the holders of Certificates of each Class
affected by such amendment (including, for the avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not
less than 51% of the aggregate Percentage Interests constituting the Class and any Companion Loan Holder if materially and adversely
affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Trust
and Servicing Agreement or of modifying in any manner the rights of the holders of the Certificates; provided, however,
that certain specified amendments require the consent of the holders of all Certificates representing all of the Percentage Interests
of the Class or Classes adversely affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the
foregoing, no amendment to the Trust and Servicing Agreement may be made that changes in any manner the obligations of the Loan
Seller under the Trust and Servicing Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the
rights of any Initial Purchaser under the Trust and Servicing Agreement without the written consent of such Initial Purchaser,
or that adversely affects the rights and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement
without the consent of such Companion Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated
to, enter into any amendment to the Trust and Servicing Agreement that it determines affects its rights, duties or immunities
or creates any additional liability for the Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition,
no amendment may be made to the Trust and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer
and the Special Servicer have first received an Opinion of Counsel (at the expense of the requesting party, if applicable, and
otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)
to the effect that the amendment is authorized or permitted under the Trust and Servicing Agreement and all conditions precedent
have been met and that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator or any other specified person in accordance with the amendment, will not result in
the imposition of any tax on any portion of the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to
qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the Code.

 

The Trust and Servicing
Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer, the Depositor, the
Certificate Administrator

in the Controlling Class, the Risk Retention Consultation Party or any of the respective affiliates, directors, officers, shareholders,

each Determination Date, commencing in June 2017 (each such date, a “Distribution Date”), to the Person in
whose name this Certificate is registered as of the related Record Date, which will be the close of business on the last day of
the calendar month preceding the month in which such Distribution Date occurs or, if such last day is not a Business Day, the

in the Trust and Servicing Agreement.

 

All
distributions will be made to the Persons entitled thereto by check mailed by first class mail to the address set forth therefor
in the Certificate Register or, provided that such Certificateholder shall have provided the Certificate Administrator with a
written request for payment by wire transfer, together with wire instructions, at least five Business Days prior to the related
Distribution Date, by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other
entity located in the United States and having appropriate facilities therefor. The final distribution on each Certificate shall

duties and immunities of the Certificate Administrator.

 

As
provided in the Trust and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for
registration of transfer of any Certificate, the Certificate Registrar 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.

 

    Exhibit A-14-5 

     

    

 

Prior
to due presentation of this Certificate for registration of transfer, the Certificate Administrator, the Trustee, the Servicer,
the Special Servicer, the Certificate Registrar, and any agent of the Certificate Administrator, the Trustee, the Servicer, the
Special Servicer 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 Trust and Servicing Agreement and for all other
purposes whatsoever, and neither the Certificate Administrator, the Trustee, the Servicer, the Special Servicer, the Certificate
Registrar, nor any agent of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer or the Certificate
Registrar shall be affected by any notice to the contrary.

 

The
Trust and Servicing Agreement may be amended from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate
Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Loan Holders, in certain
circumstances specified in the Trust and Servicing Agreement, subject to certain exceptions set forth in the Trust and Servicing
Agreement. The Trust and Servicing Agreement may also be amended from time to time by the Depositor, the Servicer, the Special
Servicer, the Certificate Administrator and the Trustee with the written consent of the holders of Certificates of each Class
affected by such amendment (including, for the avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not
less than 51% of the aggregate Percentage Interests constituting the Class and any Companion Loan Holder if materially and adversely
affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Trust
and Servicing Agreement or of modifying in any manner the rights of the holders of the Certificates; provided, however,
that certain specified amendments require the consent of the holders of all Certificates representing all of the Percentage Interests
of the Class or Classes adversely affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the
foregoing, no amendment to the Trust and Servicing Agreement may be made that changes in any manner the obligations of the Loan
Seller under the Trust and Servicing Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the
rights of any Initial Purchaser under the Trust and Servicing Agreement without the written consent of such Initial Purchaser,
or that adversely affects the rights and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement
without the consent of such Companion Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated
to, enter into any amendment to the Trust and Servicing Agreement that it determines affects its rights, duties or immunities
or creates any additional liability for the Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition,
no amendment may be made to the Trust and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer
and the Special Servicer have first received an Opinion of Counsel (at the expense of the requesting party, if applicable, and
otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)
to the effect that the amendment is authorized or permitted under the Trust and Servicing Agreement and all conditions precedent
have been met and that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator or any other specified person in accordance with the amendment, will not result in
the imposition of any tax on any portion of the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to
qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the Code.

 

    Exhibit A-14-6 

     

    

 

The
Trust and Servicing Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer,
the Depositor, the Certificate Administrator and the Trustee created thereby with respect to the Certificates (other than (i)
the obligation to make certain payments to the Senior Companion Loan Holders, (ii) the obligation of the Certificate Administrator
to make certain payments to Certificateholders after the final Distribution Date and (iii) the indemnification obligations of
the parties thereto) shall terminate upon the last action required to be taken by the Certificate Administrator on the final Distribution
Date pursuant to Article 10 of the Trust and Servicing Agreement following the later of (i) the final payment on the Certificates
or (ii) the liquidation of the Trust Loan or the liquidation or abandonment of the Property and all other Collateral for the Whole
Loan; provided, however, that in no event shall the Trust 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’s,
living on the date hereof.

the RR Interest over other Classes of the Certificates, (v) shall have no liability whatsoever to the Trust, the other parties
hereto, the Certificateholders or any other person (including any Borrower Affiliate) for having acted in accordance with or as
permitted under the terms of this Agreement, and the Certificateholders may not take any action whatsoever against the Directing
Holder, the holders of the Certificates in the Controlling Class, the Risk Retention Consultation Party or any of the respective
affiliates, directors, officers, shareholders, members, partners, agents or principals of the Directing Holder, the holders of
the Certificates in the Controlling Class or the Risk Retention Consultation Party as a result of the Directing Holder, the holders

Class
V1-A, Class V1-XB, Class V1-B, Class V1-C, Class V1-E and Class R Certificates (collectively with the Class V2 Certificates, the
“Certificates”; the holders of Certificates issued under the Trust and Servicing Agreement are collectively
referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Trust and Servicing Agreement, dated as of May 1, 2017
(the “Trust and Servicing Agreement”), by and among Natixis Commercial Mortgage Securities LLC, as Depositor,
KeyBank National Association, as Servicer and Special Servicer and Wells Fargo Bank, National Association, as Trustee, Certificate
Administrator and Custodian. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned
thereto in the Trust and Servicing Agreement.

 

Pursuant
to the terms of the Trust and Servicing Agreement, the Certificate Administrator will distribute, on the 4th Business Day after
each Determination Date, commencing in June 2017 (each such date, a “Distribution Date”), to the Person in
whose name this Certificate is registered as of the related Record Date, which will be the close of business on the last day of
the calendar month preceding the month in which such Distribution Date occurs or, if such last day is not a Business Day, the
Business Day immediately preceding such 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 and any Yield Maintenance
Premiums then distributable, if any, allocable to the Class V2 Certificates for such Distribution Date, all as more fully described
in the Trust and Servicing Agreement.

 

All
distributions will be made to the Persons entitled thereto by check mailed by first class mail to the address set forth therefor
in the Certificate Register or, provided that such Certificateholder shall have provided the Certificate Administrator with a
written request for payment by wire transfer, together with wire instructions, at least five Business Days prior to the related
Distribution Date, by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other
entity located in the United States and having appropriate facilities therefor. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the location that is specified in the notice
to Certificateholders of such final distribution.

 

This
Certificate does not purport to summarize the Trust and Servicing Agreement, and reference is made to the Trust 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.

 

As
provided in the Trust and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for
registration of transfer of any Certificate, the Certificate Registrar 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 Certificate Administrator, the Trustee, the
Servicer, the Special Servicer, the Certificate

 

    Exhibit A-15-5 

     

    

 

Registrar,
and any agent of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer 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 Trust and Servicing Agreement and for all other purposes whatsoever, and neither the Certificate Administrator,
the Trustee, the Servicer, the Special Servicer, the Certificate Registrar, nor any agent of the Certificate Administrator, the
Trustee, the Servicer, the Special Servicer or the Certificate Registrar shall be affected by any notice to the contrary.

 

The
Trust and Servicing Agreement may be amended from time to time by the Depositor, the Servicer, the Special Servicer, the Certificate
Administrator and the Trustee, without the consent of any of the Certificateholders or the Companion Loan Holders, in certain
circumstances specified in the Trust and Servicing Agreement, subject to certain exceptions set forth in the Trust and Servicing
Agreement. The Trust and Servicing Agreement may also be amended from time to time by the Depositor, the Servicer, the Special
Servicer, the Certificate Administrator and the Trustee with the written consent of the holders of Certificates of each Class
affected by such amendment (including, for the avoidance of doubt, any Holder of an RR Interest) evidencing, in each case, not
less than 51% of the aggregate Percentage Interests constituting the Class and any Companion Loan Holder if materially and adversely
affected, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Trust
and Servicing Agreement or of modifying in any manner the rights of the holders of the Certificates; provided, however,
that certain specified amendments require the consent of the holders of all Certificates representing all of the Percentage Interests
of the Class or Classes adversely affected thereby and the consent of any affected Companion Loan Holder. Notwithstanding the
foregoing, no amendment to the Trust and Servicing Agreement may be made that changes in any manner the obligations of the Loan
Seller under the Trust and Servicing Agreement or under the Loan Purchase Agreement without the consent of the Loan Seller, the
rights of any Initial Purchaser under the Trust and Servicing Agreement without the written consent of such Initial Purchaser,
or that adversely affects the rights and/or obligations, if any, of a Companion Loan Holder under the Trust and Servicing Agreement
without the consent of such Companion Loan Holder, and the Certificate Administrator or Trustee may, but will not be obligated
to, enter into any amendment to the Trust and Servicing Agreement that it determines affects its rights, duties or immunities
or creates any additional liability for the Certificate Administrator or Trustee under the Trust and Servicing Agreement. In addition,
no amendment may be made to the Trust and Servicing Agreement unless the Certificate Administrator, the Trustee, the Servicer
and the Special Servicer have first received an Opinion of Counsel (at the expense of the requesting party, if applicable, and
otherwise or if at the Trustee’s or the Certificate Administrator’s request, then at the Trust Fund’s expense)
to the effect that the amendment is authorized or permitted under the Trust and Servicing Agreement and all conditions precedent
have been met and that the amendment or the exercise of any power granted to the Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator or any other specified person in accordance with the amendment, will not result in
the imposition of any tax on any portion of the Trust or cause either the Lower-Tier REMIC or the Upper-Tier REMIC to fail to
qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the Code.

 

The
Trust and Servicing Agreement provides that the respective obligations and responsibilities of the Servicer, the Special Servicer,
the Depositor, the Certificate Administrator

 

    Exhibit A-15-6 

     

    

 

and
the Trustee created thereby with respect to the Certificates (other than (i) the obligation to make certain payments to the Senior
Companion Loan Holders, (ii) the obligation of the Certificate Administrator to make certain payments to Certificateholders after
the final Distribution Date and (iii) the indemnification obligations of the parties thereto) shall terminate upon the last action
required to be taken by the Certificate Administrator on the final Distribution Date pursuant to Article 10 of the Trust and Servicing
Agreement following the later of (i) the final payment on the Certificates or (ii) the liquidation of the Trust Loan or the liquidation
or abandonment of the Property and all other Collateral for the Whole Loan; provided, however, that in no event shall the
Trust 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’s, living on the date hereof.

 

By
its acceptance of a Certificate, each Certificateholder acknowledges and agrees that the Directing Holder, the Holders of the
Certificates in the Controlling Class and the Risk Retention Consultation Party (i) may each have special relationships and interests
that conflict with those of Certificateholders of one or more Classes of the Certificates, including owning any interest in the
Mezzanine Loan, (ii) may act solely in its own interests or in the interests of the holders of the Controlling Class or the RR
Interest, (iii) do not have any duties or liability to the Issuing Entity or to the Holders of any Class of Certificates, (iv)
may take actions that favor the interests of the Companion Loans or the interests of one or more Classes of the Certificates or
the RR Interest over other Classes of the Certificates, (v) shall have no liability whatsoever to the Trust, the other parties
hereto, the Certificateholders or any other person (including any Borrower Affiliate) for having acted in accordance with or as
permitted under the terms of this Agreement, and the Certificateholders may not take any action whatsoever against the Directing
Holder, the holders of the Certificates in the Controlling Class, the Risk Retention Consultation Party or any of the respective
affiliates, directors, officers, shareholders, members, partners, agents or principals of the Directing Holder, the holders of
the Certificates in the Controlling Class or the Risk Retention Consultation Party as a result of the Directing Holder, the holders
of the Certificates in the Controlling Class or the Risk Retention Consultation Party having acted in accordance with the terms
of and as permitted under the Trust and Servicing Agreement.

Depositor’s 17g-5 website after the Closing Date (as defined in the Trust and Servicing Agreement). Information provided
by each Furnishing Entity is labeled as provided by the specific Furnishing Entity.

 

Definition of Confidential Information.
For purposes of this Confidentiality Agreement, the term “Confidential Information” shall include the following
information (irrespective of its source or form of communication, including information obtained by you through access to this
site) that may be furnished to you by or on behalf of a Furnishing Entity in connection with the issuance or monitoring of a rating
with respect to the Certificates: (x) all data, reports, interpretations, forecasts, records, agreements, legal documents and
other information (such information, the “Evaluation Material”) and (y) any of the terms, conditions or other
facts with respect to the transactions contemplated by the Pooling and Servicing Agreement, including the status thereof; provided,
however, that the term Confidential Information shall not include information which:

 

was or becomes generally
available to the public (including through filing with the Securities and Exchange Commission or disclosure in an offering document)
other than as a result of a disclosure by you or a NRSRO Representative (as defined in Section 2(c)(i) below) in violation
of this Confidentiality Agreement;

 

was or is lawfully
obtained by you from a source other than a Furnishing Entity or its representatives that (i) is reasonably believed by you to
be under no obligation to maintain the information as confidential and (ii) provides it to you without any obligation to maintain
the information as confidential; or

 

is
independently developed by the NRSRO without reference to any Confidential Information.

 

Information to Be Held in Confidence.

 

You will use the Confidential
Information solely for the purpose of determining or monitoring a credit rating on the Certificates and, to the extent that any
information used is derived from but does not reveal any Confidential Information, for benchmarking, modeling or research purposes
(the “Intended Purpose”).

 

You acknowledge that
you are aware that the United States and state securities laws impose restrictions on trading in securities when in possession
of material, non-public information and that the NRSRO will advise (through policy manuals or otherwise) each NRSRO Representative
who is informed of the matters that are the subject of this Confidentiality Agreement to that effect.

 

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

 

    Exhibit L-1

     

    

 

- disclose
the Confidential Information to any of the NRSRO’s affiliates, directors, officers, employees, legal representatives, agents
and advisors (each, a “NRSRO Representative”) who, in the reasonable judgment of the NRSRO, need to know such
Confidential Information in connection with the Intended Purpose; provided, that, prior to disclosure of the Confidential
Information to a NRSRO Representative, the NRSRO shall have taken reasonable precautions to ensure, and shall be satisfied, that
such NRSRO Representative will act in accordance with this Confidentiality Agreement;

 

-
solely to the extent required for compliance with Rule 17g-5(a)(3) of the Act (17 C.F.R. 240.17g-5),post the Confidential Information

-
use information derived from the Confidential Information in connection with an Intended Purpose, if such derived information
does not reveal any Confidential Information.

 

Disclosures Required by Law. If
you or any NRSRO Representative is requested or required (orally or in writing, by interrogatory, subpoena, civil investigatory
demand, request for information or documents, deposition or similar process relating to any legal proceeding, investigation, hearing
or otherwise) to disclose any Confidential Information, you agree to provide the relevant Furnishing Entity with notice as soon
as practicable (except in the case of regulatory or other governmental inquiry, examination or investigation, and otherwise to
the extent practical and permitted by law, regulation or regulatory or other governmental authority) that a request to disclose
the Confidential Information has been made so that the relevant Furnishing Entity may seek an appropriate protective order or
other reasonable assurance that confidential treatment will be accorded the Confidential Information if it so chooses. Unless
otherwise required by a court or other governmental or regulatory authority to do so, and provided that you been informed by written
notice that the related Furnishing Entity is seeking a protective order or other reasonable assurance for confidential treatment
with respect to the requested Confidential Information, you agree not to disclose the Confidential Information while the Furnishing
Entity’s effort to obtain such a protective order or other reasonable assurance for confidential treatment is pending. You
agree to reasonably cooperate with each Furnishing Entity in its efforts to obtain a protective order or other reasonable assurance
that confidential treatment will be accorded to the portion of the Confidential Information that is being disclosed, at the sole
expense of such Furnishing Entity; provided, however, that in no event shall the NRSRO be required to take a position
that such information should be entitled to receive such a protective order or reasonable assurance as to confidential treatment.
If a Furnishing Entity succeeds in obtaining a protective order or other remedy, you agree to comply with its terms with respect
to the disclosure of the Confidential Information, at the sole expense of such Furnishing Entity. If a protective order or other
remedy is not obtained or if the relevant Furnishing Entity waives compliance with the provisions of this Confidentiality Agreement
in writing, you agree to furnish only such information as you are legally required to disclose, at the sole expense of the relevant
Furnishing Entity.

 

Obligation to Return Evaluation Material.
Promptly upon written request by or on behalf of the relevant Furnishing Entity, all material or documents, including copies thereof,
that contain Evaluation Material will be destroyed or, in your sole discretion, returned to the relevant Furnishing Entity. Notwithstanding
the foregoing, (a) the NRSRO may retain one or more copies of any document or other material containing Evaluation Material to
the extent necessary for legal or regulatory compliance (or compliance with the NRSRO’s internal policies and procedures
designed to ensure legal or regulatory compliance) and (b) the NRSRO may retain any portion of the Evaluation Material that may
be found in backup tapes or other archive or electronic media or other documents prepared by the NRSRO and any Evaluation Material
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.

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.

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 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.

your obligations under this Confidentiality Agreement will survive indefinitely.

4.             That

and the Purchaser intends to pay taxes associated with holding the Residual Certificate as they become due.

 

5.             That
the Purchaser understands that it may incur tax liabilities with respect to the Residual Certificate in excess of any cash flow

6.             That

affidavit substantially in the form of this affidavit or as to which the Purchaser has actual knowledge that the requirements

12.           Check
the applicable paragraph:

 

☐            The
present value of the anticipated tax liabilities associated with holding the Residual Certificate, as applicable, does not exceed
the sum of:

 

(i)            the
present value of any consideration given to the Purchaser to acquire such Residual Certificate;

 

(ii)           the
present value of the expected future distributions on such Certificate; and

 

(iii)          the
present value of the anticipated tax savings associated with holding such Residual Certificate as the related REMIC generates
losses.

 

For purposes of this calculation, (i)
the Purchaser is assumed to pay tax at the highest rate currently specified in Code Section 11(b) (but the tax rate in Code Section
55(b)(1)(B) may be used in lieu of the highest rate specified in Code Section 11(b) if the Purchaser has been subject to the alternative
minimum tax under Code Section 55 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 Code Section 1274(d) for the month of the transfer and the compounding period used by the Purchaser.

 

    Exhibit M-1-2

     

    

 

☐           The
transfer of the Residual Certificate complies with U.S. Treasury Regulations Section 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 Residual 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 Residual Certificate only to another “eligible corporation,” as defined in U.S. Treasury
Regulations Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of Section 1.860E-1(c)(4)(i), (ii) and
(iii) and Section 1.860E-1(c)(5) of the U.S. Treasury Regulations; and

 

(iv)
      the Purchaser determined the consideration paid to it to acquire the Residual 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.

any other action with respect to the Excess Servicing Fee Right, any interest in the Excess Servicing Fee Right or any other similar
security, which (in the case of any of the acts described in clauses (a) through (e) above) would constitute a distribution of

For so long as any Other Securitization Trust is subject to the reporting requirements of the Exchange
Act, the parties identified in the “Party Responsible” column are obligated pursuant to Section 13.5 of the Trust and
Servicing Agreement to disclose to each Other Exchange Act Reporting Party and each Other Depositor to which the particular Additional
Form 10-K Disclosure is relevant for Exchange Act reporting purposes, any information described in the corresponding Form 10-K
Item described in the “Item on Form 10- K” column to the extent such party has knowledge (and in the case of net operating
income information, financial statements, annual operating statements, budgets and/or rent rolls required to be provided in connection
with 1112(b) below, possession) of such information (other than information as to itself). Each of the Certificate Administrator,
the Trustee, the Servicer, the Special Servicer, each Other Exchange Act Reporting Party and the Other Depositor (in its capacity
as such) shall be entitled to rely on the accuracy of the Offering Circular and the offering materials with respect to any related
Other Securitization Trust (other than information with respect to itself that is set forth in or omitted from such offering materials
or the Offering Circular), in the absence of specific notice to the contrary from the Depositor, Other Depositor or the Trust Loan
Seller. Each of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer, each Other Exchange Act Reporting
Party and the Other Depositor (in its capacity as such) shall be entitled to assume that there is no “significant obligor”
other than a party or property identified as such in the prospectus relating to the Other Securitization and to assume that no
other party or property will constitute a “significant obligor” after the Cut-off Date. In no event shall the Servicer
or the Special Servicer be required to provide any information for inclusion in a Form 10-K that relates to any Mortgage Loan for
which the Servicer or the Special Servicer is not the applicable Servicer or Special Servicer, as the case may be. For this Agreement
and any Other Securitization Trust, each of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer, each
Other Exchange Act Reporting Party and the Other Depositor (in its capacity as such) shall be entitled to assume that there is
no provider of credit enhancement, liquidity or derivative instruments within the meaning of Items 1114 or 1115 of Regulation AB
other than a party identified as such in the Offering Circular and the offering materials with respect to any related Other Securitization
Trust.

relevant for Exchange Act reporting purposes, the occurrence of any event described in the corresponding Form 8-K Item described
in the “Item on Form 8-K” column to the extent such party has knowledge of such information (other than information
as to itself). Each of the Certificate Administrator, the Trustee, the Servicer, the Special Servicer, each Other Exchange Act
Reporting Party and the Other Depositor (in its capacity as such) shall be entitled to rely on the accuracy of the Offering Circular
and the offering materials with respect to any related Other Securitization Trust (other than information with respect to itself
that is set forth in or omitted from such offering materials or the Offering Circular), in the absence of specific notice to the
contrary from the Depositor, Other Depositor or the Trust Loan Seller. Each of the Certificate Administrator, the Trustee, the
Servicer, the Special Servicer, each Other Exchange Act Reporting Party and the Other Depositor (in its capacity as such) shall
be entitled to assume that there is no “significant obligor” other than a party or property identified as such in
the prospectus relating to the Other Securitization and to assume that no other party or property will constitute a “significant
obligor” after the Cut-off Date. In no event shall the Servicer or the Special Servicer be required to provide any information
for inclusion in a Form 8-K that relates to any Mortgage Loan for which the Servicer or the Special Servicer is not the applicable
Servicer or Special Servicer, as the case may be. For this Agreement and any Other Securitization Trust, each of the Certificate
Administrator, the Trustee, the Servicer, the Special Servicer, each Other Exchange Act Reporting Party and the Other Depositor
(in its capacity as such) shall be entitled to assume that there is no provider of credit enhancement, liquidity or derivative
instruments within the meaning of Items 1114 or 1115 of Regulation AB other than a party identified as such in the Offering Circular
and the offering materials with respect to any related Other Securitization Trust.

This
Pooling and Servicing Agreement is dated and effective as of April 1, 2017, among Wells Fargo Commercial Mortgage Securities,
Inc., as Depositor, Wells Fargo Bank, National Association, as Master Servicer, Rialto Capital Advisors, LLC, as Special Servicer,
Wells Fargo Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, and
Pentalpha Surveillance LLC, as Operating Advisor and as Asset Representations Reviewer.

 

PRELIMINARY
STATEMENT:

 

The
Depositor intends to sell commercial mortgage pass-through certificates (collectively, the “Certificates”),
to be issued hereunder in multiple classes (each, a “Class”), which in the aggregate will evidence the entire
beneficial ownership interest in the Trust to be created hereunder, the primary assets of which will be a pool of commercial mortgage
loans. As provided herein, the Certificate Administrator shall elect or shall cause an election to be made to treat designated
portions of the Trust (exclusive of the Excess Interest and the proceeds thereof in the Excess Interest Distribution Account)
for federal income tax purposes as two (2) separate real estate mortgage investment conduits (the “Upper-Tier REMIC”
and the “Lower-Tier REMIC”, and each a “Trust REMIC” as described herein).

 

In
addition, the parties intend that the portion of the Trust Fund consisting of the Class V Specific Grantor Trust Assets and the
RR Interest Specific Grantor Trust Assets shall be treated as a grantor trust under subpart E, part I of subchapter J of the Code
for federal income tax purposes (the “Grantor Trust”). Solely for tax purposes, the Class V Certificates and
the RR Interest shall represent undivided beneficial interests in the Class V Specific Grantor Trust Assets and the RR Interest
Specific Grantor Trust Assets, respectively. As provided herein, the Certificate Administrator shall take all actions expressly
required hereunder to ensure that the portion of the Trust Fund consisting of the Grantor Trust maintains its status as a grantor
trust under federal income tax law and not be treated as part of either Trust REMIC.

 

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

 

LOWER-TIER
REMIC

 

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

 

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

	Class
    LF	 	(1)	 	$	10,775,000	 
	Class
    LG	 	(1)	 	$	43,100,400	 
	Class
    LR	 	None(2)	 		None	 
	LRR	 	(1)	 	$	50,409,442	 

 

 

 

		(1)	The
                                         interest rate for each Class of Lower-Tier Regular Interests on any Distribution Date
                                         will be the Weighted Average Net Mortgage Rate for such Distribution Date.

 

		(2)	The
                                         Class LR Interest (evidenced by the Class R Certificates) will not have a Certificate
                                         Balance or Notional Amount, will not bear interest and will not be entitled to distributions
                                         of Prepayment Premiums or Yield Maintenance Charges. Any Aggregate Available Funds remaining
                                         in the Lower-Tier REMIC Distribution Account after distributing the Lower-Tier Distribution
                                         Amount will be deemed distributed to the Class LR Interest and shall be payable to the
                                         Holders of the Class R Certificates.

 

UPPER-TIER
REMIC

A-4, Class X-A, Class X-B, Class X-D, Class X-E, Class X-F, Class X-G, Class A-S, Class B, Class C, Class D, Class E, Class F
and Class G Regular Certificates and the RR Interest (exclusive of the portion of the RR Interest representing an interest in
the Grantor Trust), each of which is a “regular interest” in the Upper-Tier REMIC created hereunder. The Upper-Tier
REMIC also will issue the uncertificated Class UR Interest, which is the sole Class of “residual interests” in the
Upper-Tier REMIC for purposes of the REMIC Provisions and is represented by the Class R Certificates.

 

THE
GRANTOR TRUST

 

The
Class V Certificates and the RR Interest shall represent undivided beneficial interests in the Grantor Trust consisting of the
Class V Specific Grantor Trust Assets and the RR Interest Specific Grantor Trust Assets, respectively, as described herein. As
provided herein, the Certificate Administrator shall not take any actions that would cause the portion of the Trust Fund consisting
of the Grantor Trust (i) to fail to maintain its status as a “grantor trust” under federal income tax law or (ii)
to be treated as part of any Trust REMIC.

writing, to exercise any of the rights of the Controlling Class Certificateholder and such rights have not been reinstated to
a successor controlling class certificateholder pursuant to Section 3.23(l), provided, however, that a Control

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

 

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

 

“Nonrecoverable
P&I Advance”: Any P&I Advance previously made or proposed to be made in respect of a Mortgage Loan (including
any Non-Serviced Mortgage Loan) or REO Loan (other than any portion of an REO Loan related to a Companion Loan) which, in the
reasonable judgment of the Master Servicer, the Special Servicer or the Trustee, as the case may be, will not be ultimately recoverable,
together with any accrued and unpaid interest thereon at the Reimbursement Rate, from Late Collections or any other recovery on
or in respect of such Mortgage Loan or REO Loan; provided, however, that the Special Servicer may, at its option,
make a determination in accordance with the Servicing Standard, that any P&I Advance previously made or proposed to be made
is a Nonrecoverable P&I Advance and shall deliver to the Master Servicer (and with respect to a Serviced Mortgage Loan, to
any Other Servicer, and with respect to a Non-Serviced Mortgage Loan, to the related Non-Serviced Master Servicer and Non-Serviced
Special Servicer), the Certificate Administrator, the Trustee, the Operating Advisor and the 17g-5 Information Provider notice
of such determination. Any such determination (other than by the Special Servicer) shall not be binding upon (but may be conclusively
relied upon by) the Master Servicer and the Trustee, and any such determination by the Special Servicer shall be conclusive and
binding upon the Master Servicer and the Trustee (but this statement shall not be construed to entitle the Special Servicer to
reverse the determination of the Master Servicer or the Trustee or to prohibit the Master Servicer or the Trustee from making
a determination that a P&I Advance would be a Nonrecoverable Advance), provided, however, that the Special Servicer
shall have no such obligation to make an affirmative determination that any P&I Advance is or would be recoverable and in
the absence of a determination by the Special Servicer that such P&I Advance is or would be a Nonrecoverable P&I Advance,
such decision shall remain with the Master Servicer or Trustee, as applicable. If the Special Servicer makes a determination that
only a portion, and not all, of any previously made or proposed P&I Advance is a Nonrecoverable P&I Advance, the Master
Servicer and the Trustee shall have the right to make its own subsequent determination that any remaining portion of any such
previously made or proposed P&I Advance is a Nonrecoverable P&I Advance. With respect to any Non-Serviced Whole Loan,
if any Non-Serviced Master Servicer, Non-Serviced Trustee or Non-Serviced Special Servicer, as applicable, in connection with
a securitization of the related Non-Serviced Companion Loan determines that a principal and interest advance with

 

     -72-

     

    

 

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

 

     -73-

     

    

 

determination,
shall be evidenced by an Officer’s Certificate delivered by either the Special Servicer or the Master Servicer to the other
and to the Trustee, the Certificate Administrator and the Directing Certificateholder (but in the case of the Directing Certificateholder,
only prior to the occurrence and continuance of a Consultation Termination Event and only with respect to any Mortgage Loan other
than an Excluded Loan as to such party) (and in the case of a Serviced Mortgage Loan, any Other Servicer), the Operating Advisor
(but only in the case of the Special Servicer) and the Depositor, or by the Trustee to the Depositor, the Master Servicer, the
Special Servicer, the Operating Advisor and the Certificate Administrator (and, in the case of a Serviced Mortgage Loan, any Other
Servicer). The Officer’s Certificate shall set forth such determination of nonrecoverability and the considerations of the
Master Servicer, the Special Servicer or the Trustee, as applicable, forming the basis of such determination (which shall be accompanied
by, to the extent available, related income and expense statements, rent rolls, occupancy status, property inspections and any
other information used by the Master Servicer, the Special Servicer or the Trustee, as applicable, to make such determination
and shall include any existing Appraisal of the related Mortgage Loan or the related Mortgaged Property). The Trustee shall be
entitled to conclusively rely on the Master Servicer’s or the Special Servicer’s determination that a P&I Advance
is or would be nonrecoverable, and the Master Servicer shall be entitled to conclusively rely on the Special Servicer’s
determination that a P&I Advance is or would be nonrecoverable. In the case of a cross-collateralized Mortgage Loan (if any),
such recoverability determination shall take into account the cross-collateralization of the related cross-collateralized Mortgage
Loan.

 

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

 

     -74-

     

    

 

considering whether a Servicing Advance is a Nonrecoverable
Servicing Advance, will be entitled to give due regard to the existence of any Nonrecoverable Advance or Workout-Delayed Reimbursement
Amounts with respect to other Mortgage Loans, the reimbursement of which, at the time of such consideration, is being deferred
or delayed by the Master Servicer, in light of the fact that proceeds on the related Mortgage Loan are a source of recovery not
only for the Servicing Advance under consideration, but also as a potential source of recovery of such Nonrecoverable Advance
or Workout-Delayed Reimbursement Amounts which are or may be being deferred or delayed. In addition, any such Person may update
or change its recoverability determinations at any time (but not reverse any other Person’s determination that an Advance
is a Nonrecoverable Advance) and, consistent with the Servicing Standard, in the case of the Master Servicer or in its good faith
business judgment in the case of the Trustee (solely in its capacity as Trustee), may obtain at the expense of the Trust any reasonably
required analysis, Appraisals or market value estimates or other information for making a recoverability determination. Absent
bad faith, the Master Servicer’s, the Special Servicer’s or the Trustee’s determination as to the recoverability
of any Servicing Advance shall be conclusive and binding on the Certificateholders. The determination by the Master Servicer,
the Special Servicer or the Trustee, as the case may be, that a Nonrecoverable Servicing Advance has been made or that any proposed
Servicing Advance, if made, would constitute a Nonrecoverable Servicing Advance, or any updated or changed recoverability determination,
shall be evidenced by an Officer’s Certificate delivered by either the Special Servicer or the Master Servicer to the other
and to the Trustee, the Certificate Administrator, the Directing Certificateholder (but in the case of the Directing Certificateholder,
only prior to the occurrence and continuance of a Consultation Termination Event and only with respect to any Mortgage Loan other
than an Excluded Loan as to such party) (and in the case of a Serviced Mortgage Loan, any Other Servicer), the Operating Advisor
(but only in the case of the Special Servicer) and the Depositor, or by the Trustee to the Depositor, the Master Servicer, the
Special Servicer, the Operating Advisor and the Certificate Administrator (and in the case of a Serviced Mortgage Loan, any Other
Servicer); provided, however, that the Special Servicer may, at its option, make a determination in accordance with
the Servicing Standard, that any Servicing Advance previously made or proposed to be made is a Nonrecoverable Servicing Advance
and shall deliver to the Master Servicer (and with respect to a Serviced Mortgage Loan, to any Other Servicer), the Certificate
Administrator, the Trustee, the Operating Advisor and the 17g-5 Information Provider notice of such determination. Any such determination
(other than by the Special Servicer) shall not be binding upon (but may be conclusively relied upon by) the Master Servicer and
the Trustee, and any such determination by the Special Servicer shall be binding upon the Master Servicer and the Trustee (but
this statement shall not be construed to entitle the Special Servicer to reverse the determination of the Master Servicer or the
Trustee or to prohibit the Master Servicer or the Trustee from making a determination that a Servicing Advance would be a Nonrecoverable
Advance), provided, however, that the Special Servicer shall have no such obligation to make an affirmative determination
that any Servicing Advance is or would be recoverable and in the absence of a determination by the Special Servicer that such
Servicing Advance is or would be a Nonrecoverable Servicing Advance, such decision shall remain with the Master Servicer or the
Trustee, as applicable. If the Special Servicer makes a determination that only a portion, and not all, of any previously made
or proposed Servicing Advance is a Nonrecoverable Servicing Advance, the Master Servicer and the Trustee shall each have the right
to make its own subsequent determination that any remaining portion of any such previously made or proposed

Servicing Advance
is a Nonrecoverable Servicing Advance. The Officer’s Certificate shall set forth such determination of nonrecoverability
and the considerations of the Master Servicer, the Special Servicer or the Trustee, as applicable, forming the basis of such determination
(which shall be accompanied by, to the extent available, related income and expense statements, rent rolls, occupancy status,
property inspections and any other information used by the Master Servicer, the Special Servicer or the Trustee, as applicable,
to make such determination and shall include any existing Appraisal with respect to the related Mortgage Loan, Serviced Companion
Loan or related Mortgaged Property). The Special Servicer shall promptly furnish any party required to make Servicing Advances
hereunder with any information in its possession regarding the Specially Serviced Loans and REO Properties as such party required
to make Servicing Advances may reasonably request for purposes of making recoverability determinations. The Trustee shall be entitled
to conclusively rely on the Master Servicer’s or the Special Servicer’s determination that a Servicing Advance is
or would be nonrecoverable, and the Master Servicer shall be entitled to conclusively rely on the Special Servicer’s determination
that a Servicing Advance is or would be nonrecoverable. Notwithstanding anything herein to the contrary, if the Special Servicer
requests that the Master Servicer make a Servicing Advance, the Master Servicer may conclusively rely on such request as evidence
that such advance is not a Nonrecoverable Servicing Advance; provided, however, that the Special Servicer shall
not be entitled to make such a request more frequently than once per calendar month with respect to Servicing Advances other than
emergency advances (although such request may relate to more than one Servicing Advance). In the case of a cross-collateralized
Mortgage Loan (if any), such recoverability determination shall take into account the cross-collateralization of the related cross-collateralized
Mortgage Loan. The determination as to the recoverability of any servicing advance or property protection advance previously made
or proposed to be made in respect of a Non-Serviced Whole Loan shall be made by the related Non-Serviced Master Servicer, Non-Serviced
Special Servicer or Non-Serviced Trustee, as the case may be, pursuant to the related Non-Serviced PSA.

basis as of the Closing Date as to such non-delivered document or instrument, and such non-delivered document or instrument shall
be deemed to have been included in the Mortgage File, if a duplicate original or a photocopy of such non-delivered document or
instrument (certified by the applicable public filing or recording office, the applicable title insurance company or the applicable
Mortgage Loan Seller to be a true and complete copy of the original thereof submitted or to be submitted for filing or recording)
is delivered to the Custodian on or before the date set forth herein, and either the original of such non-delivered document or
instrument, or a photocopy thereof (certified by the appropriate county recorder’s office or the applicable title insurance
company, in the case of the documents and/or instruments referred to in clause (ii) of the definition of “Mortgage
File”, to be a true and complete copy of the original thereof submitted for recording), with evidence of filing or recording
thereon, is delivered to the Custodian within one hundred-eighty (180) days of the Closing Date (or within such longer period,
not to exceed eighteen (18) months, after the Closing Date as the Custodian shall consent to as long as the applicable Mortgage
Loan Seller is, as certified in writing to the Trustee and the Custodian no less often than every ninety (90) days following such
180–day period after the Closing Date, attempting in good faith to obtain from the appropriate public filing office or county
recorder’s office such original or photocopy). If the applicable Mortgage Loan Seller is required to, but cannot, deliver,
or cause to be delivered, as to any Mortgage Loan, any of the documents and/or instruments referred to in clauses (ii),
(iv), (vii), and (ix) (or, if applicable, a copy thereof) of the definition of “Mortgage File,”
with evidence of filing or recording thereon (if intended to be recorded or filed), for any other reason, including, without limitation,
that such non-delivered document or instrument has been lost or destroyed, the delivery requirements of the applicable Mortgage
Loan Purchase Agreement and this Section 2.01(b) shall be deemed to have been satisfied as to such non-delivered document
or instrument, and such non-delivered document or instrument shall be deemed to have been included in the Mortgage File, if a
photocopy of such non-delivered document or instrument (with evidence of filing or recording thereon and certified in the case
of the documents and/or instruments referred to in clause (ii) of the definition of

 

     -126-

     

    

 

“Mortgage File” by the
appropriate county recorder’s office or the applicable title insurance company to be a true and complete copy of the original
thereof submitted for recording) is delivered to the Custodian on or before the date set forth herein. Neither the Trustee nor
any Custodian shall in any way be liable for any failure by any Mortgage Loan Seller or the Depositor to comply with the delivery
requirements of the related Mortgage Loan Purchase Agreement and this Section 2.01(b). If, on the Closing Date as to any
Mortgage Loan, subject to the next sentence, the applicable Mortgage Loan Seller is required to, but cannot, deliver (in complete
and recordable form or form suitable for filing or recording, if applicable) any one of the assignments in favor of the Trustee
referred to in clause (iii), clause (v), or clause (x) of the definition of “Mortgage File” solely
because of the unavailability of filing or recording information as to any existing document or instrument, such Mortgage Loan
Seller may provisionally satisfy the delivery requirements of the related Mortgage Loan Purchase Agreement and this Section
2.01(b) with respect to such assignment by delivering with respect to such Mortgage Loan on the Closing Date an omnibus assignment
of such Mortgage Loan substantially in the form of Exhibit H; provided that all required original assignments with
respect to such Mortgage Loan (in fully complete and recordable form or form suitable for filing or recording, if applicable)
are delivered to the Custodian within one hundred-eighty (180) days after the Closing Date (or within such longer period, not
to exceed eighteen (18) months, which the Custodian shall consent to so long as the applicable Mortgage Loan Seller is, as certified
in writing to the Trustee and the Custodian no less often than every ninety (90) days following such 180–day period after
the Closing Date, attempting in good faith to obtain from the appropriate public filing office or county recorder’s office
the applicable filing or recording information as to the related document or instrument); and provided, further,
that in the case of a Non-Serviced Mortgage Loan, the delivery of any such assignments shall be subject to clause (e) of
the first proviso to the definition of “Mortgage File” herein. As to any Mortgage Loan, the related Mortgage Loan
Seller or its agent is responsible for recording or filing, as applicable, any one of the assignments in favor of the Trustee
referred to in clause (iii), clause (v), or clause (x) of the definition of “Mortgage File”,
and such Mortgage Loan Seller may provisionally satisfy the delivery requirements of the related Mortgage Loan Purchase Agreement
and this Section 2.01(b) with respect to such assignment by delivering to the Custodian with respect to such Mortgage Loan
on the Closing Date a copy of such assignment in the form sent for recording or filing or (except for recording or filing information
not yet available) to be sent for recording or filing; provided that an original or copy of such assignment (with evidence
of recording or filing, as applicable, indicated thereon) shall be delivered to the Custodian as contemplated by Section 2.01(c) of this Agreement. Notwithstanding anything herein to the contrary, with respect to the delivery of a letter of credit in
the manner described in clause (A) of clause (xii) of the definition of “Mortgage File”, the applicable
Mortgage Loan Seller shall be deemed to have satisfied the delivery requirements of the related Mortgage Loan Purchase Agreement
and this Section 2.01(b) by delivering to the Custodian within ten (10) Business Days following the Closing Date with respect
to any such letter(s) of credit a copy of such letter of credit, the transfer documentation and such transmittal communication
to the issuing bank indicating that such document has been delivered to the issuing bank for reissuance. If a letter of credit
is not in a form that would allow the Master Servicer to draw on such letter of credit on behalf of the Trust in accordance with
the applicable terms thereof and/or of the related Mortgage Loan documents, the applicable Mortgage Loan Seller shall deliver
copies of the appropriate transfer or assignment documents to the Custodian promptly following receipt of

 

     -127-

     

    

 

written notification
thereof. If not otherwise paid by the related Mortgagor, the applicable Mortgage Loan Seller shall pay any transfer fee required
in order to transfer the beneficiary’s interest from such Mortgage Loan Seller to the Master Servicer on behalf of the Trust
as required hereunder and shall cooperate with the reasonable requests of the Master Servicer in connection with effectuating
a draw under any such letter of credit prior to the date such letter of credit is reissued to the Master Servicer on behalf of
the Trust. Regardless of the manner of delivery, the related Mortgage Loan Seller is required pursuant to the related Mortgage
Loan Purchase Agreement to indemnify the Trust for any liabilities, charges, costs, fees or other expenses accruing from the failure
of such Mortgage Loan Seller to assign all rights in and to the letter of credit hereunder including the right and power to draw
on the letter of credit.

 

(c)           Except
in the case of a Non-Serviced Mortgage Loan, the related Mortgage Loan Seller is required at its sole cost and expense, to itself,
or to engage a third party to, put each Assignment of Mortgage, each assignment of Assignment of Leases and each assignment of
each UCC Financing Statement (collectively, the “Assignments” and, individually, “Assignment”)
relating to the Mortgage Loans conveyed by it under the applicable Mortgage Loan Purchase Agreement in proper form for filing
or recording, as applicable, and to submit such Assignments for filing or recording, as the case may be, in the applicable public
filing or recording office. On the Closing Date, the Mortgage Loan Sellers may deliver one (1) omnibus assignment for all such
Mortgage Loans substantially in the form of Exhibit H hereto to the Custodian as provided in Section 2.01(b). Except
under the circumstances provided for in the last sentence of this Section 2.01(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

 

     -128-

     

    

 

expenses
satisfactory to the Custodian, the Custodian, at the expense of the applicable Mortgage Loan Seller, shall cause a search of the
land records of each applicable jurisdiction and of the records of the offices of the applicable Secretary of State for confirmation
that the Assignment appears in such records and retain a copy of such confirmation in the related Mortgage File. In the event
that confirmation of the recording or filing of an Assignment cannot be obtained, the Custodian or the related Mortgage Loan Seller,
as applicable, shall promptly inform the other and the Custodian shall provide such Mortgage Loan Seller with a copy of the Assignment
and request the preparation of a new Assignment. The related Mortgage Loan Seller shall pay the expenses for the preparation of
replacement Assignments for any Assignments which, having been properly submitted for filing or recording to the appropriate governmental
office by the Custodian, fail to appear of record and must be resubmitted. Notwithstanding the foregoing, there shall be no requirement
to record any assignment to the Trustee referred to in clause (iii) or (v) of the definition of “Mortgage
File,” or to file any UCC-3 to the Trustee referred to in clause (ix) of the definition of “Mortgage File,”
in those jurisdictions where, in the written opinion of local counsel (which opinion shall be an expense of the related Mortgage
Loan Seller) acceptable to the Depositor and the Trustee, such recordation and/or filing is not required to protect the Trustee’s
interest in the related Mortgage Loan against sale, further assignment, satisfaction or discharge by the related Mortgage Loan
Seller, the Master Servicer, the Special Servicer, any Sub-Servicer or the Depositor.

 

(d)       All
documents and records in the Depositor’s or the applicable Mortgage Loan Seller’s possession relating to the Mortgage
Loans (including, in the case of such Mortgage Loan Seller, originals or copies of all financial statements, operating statements,
appraisals, environmental reports, engineering reports, Insurance Policies, certificates, guaranty/indemnity agreements, property
inspection reports, escrow analysis, tax bills, third-party management agreements, asset summary and financial information on
the borrower/sponsor and any guarantor, but in any case excluding the applicable Mortgage Loan Seller’s internal communications
(including such communications between such Mortgage Loan Seller and its Affiliates) and underwriting analysis (including documents
prepared by the applicable Mortgage Loan Seller or any of its Affiliates for such purposes), draft documents, attorney-client
communications that are privileged communications or constitute legal or other due diligence analyses and credit underwriting
or due diligence analyses or data) that (i) are not required to be a part of a Mortgage File in accordance with the definition
thereof and (ii) are reasonably necessary for the servicing of each such Mortgage Loan, together with copies of all documents
in each Mortgage File, shall be delivered by the Depositor or the applicable Mortgage Loan Seller to the Master Servicer within
five (5) Business Days after the Closing Date and shall be held by the Master Servicer on behalf of the Trustee in trust for the
benefit of the Certificateholders (and as Holder of the Lower-Tier Regular Interests) and, if applicable, on behalf of the related
Companion Holder. Such documents and records shall be any documents and records (with the exception of any items excluded under
the immediately preceding sentence) that would otherwise be a part of the Servicing File.

 

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

 

     -129-

     

    

 

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

 

(g)       With
respect to the Mortgage Loans secured by the Mortgaged Properties or portfolio of Mortgaged Properties identified as J.W. Marriott
Desert Springs, Key Center Cleveland, DoubleTree Greenway Houston, B.F. Saul Hotel Portfolio, Hilton – Mystic, CT, Hilton
Garden Inn Chattanooga Downtown, Best Western – Hannaford, OH and Red Roof Inn BWI Airport on the Mortgage Loan Schedule,
which are each subject to a franchise agreement with a related comfort letter in favor of the respective Mortgage Loan Seller
that requires notice to or request of the related franchisor to transfer or assign any related comfort letter to the Trustee for
the benefit of the Certificateholders or otherwise have a new comfort letter (or any such new document or acknowledgement as may
be contemplated under the existing comfort letter) issued in the name of the Trustee for the benefit of the Certificateholders,
the related Mortgage Loan Seller or its designee shall provide any such required notice or make any such required request to the
related franchisor (with a copy of such notice or request to the Master Servicer) within forty-five (45) days of the Closing Date
(or any shorter period if required by the applicable comfort letter), and the Master Servicer shall use reasonable efforts in
accordance with the Servicing Standard to acquire such replacement comfort letter, if necessary (or to acquire any such new document
or acknowledgement as may be contemplated under the existing comfort letter). If the Master Servicer is unable to acquire any
such replacement comfort letter (or new document or acknowledgement, as applicable) within one hundred-twenty (120) days of the
Closing Date, the Master Servicer shall notify the related Mortgage Loan Seller that no such replacement comfort letter has been
received.

 

(h)      Each
Mortgage Loan Purchase Agreement shall provide that within 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 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 Directing Certificateholder, the Asset Representations Reviewer and the Operating Advisor) certifying that
the electronic copies of the documents and information uploaded to the Designated Site constitute 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 applicable Mortgage Loan Seller (the “Diligence
File Certification”).

 

(i)       [Reserved].

 

(j)       Within
five (5) Business Days after the Closing Date, the Depositor shall deliver the Initial Schedule AL File in EDGAR-Compatible Format

Section
2.02     Acceptance by Trustee. (a)The Trustee, by the execution and delivery of this Agreement (1) acknowledges
receipt by it or the 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 the 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 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 after 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
the Depositor, the Master Servicer, the Special Servicer, the Directing Certificateholder (so long as no Consultation Termination
Event shall have occurred and be continuing and only with respect to Mortgage Loans other than any Excluded Loan with respect
to the Directing Certificateholder or the Holder of the majority of the Controlling Class), the Trustee, the Certificate Administrator,
the Asset Representations Reviewer, the Operating Advisor and the applicable Mortgage Loan Seller (as to each Mortgage Loan listed
in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full)) that, except as specifically identified in any exception
report annexed to such writing (the “Custodial Exception Report”), (i) subject to the first proviso of the
definition of “Mortgage File” herein and Section 2.01, all documents specified in clauses (i) through
(v), (viii), (ix), (xi), (xii) and (xiii), if any, of the definition of “Mortgage
File”, as applicable, are in its possession, (ii) the foregoing documents delivered or caused to be delivered by the Mortgage
Loan Sellers have been reviewed by the Custodian and appear regular on their face and appear to be executed and 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), (vi) and (viii)(c) 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

 

     -131-

     

    

 

items
which were delivered by the related Mortgage Loan Seller but are out for filing or recording and have not been returned by the
filing office or the recorder’s office).

 

(c)       The
Custodian shall review the Mortgage Loan documents received subsequent to the Closing Date; and, on or about the first anniversary
of the Closing Date, the Custodian shall, in the form attached as Exhibit Q, certify in writing to each of the Depositor,
the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Directing Certificateholder and the
applicable Mortgage Loan Seller (as to each Mortgage Loan listed on the Mortgage Loan Schedule (other than any related Mortgage
Loan as to which a Liquidation Event has occurred) or any related Mortgage Loan specifically identified in any exception report
annexed to such writing) that, (i) subject to the first proviso of the definition of “Mortgage File” herein and Section
2.01, all documents specified in clauses (i) through (v), (viii), (ix), (xi), (xii)
and (xiii), if any, of the definition of “Mortgage File”, as applicable, are in its possession, (ii) the
foregoing documents delivered or caused to be delivered by the Mortgage Loan Sellers have been reviewed by the Custodian and appear
regular on their face and appear to be executed and relate to such Mortgage Loan, if applicable, and (iii) based on such examination
and only as to the foregoing documents, the information set forth in the Mortgage Loan Schedule with respect to the items specified
in clauses (iv), (vi) and (viii)(c) in the definition of “Mortgage Loan Schedule” is correct.

 

(d)       Notwithstanding
anything contained in this Section 2.02 and Section 2.03(b) to the contrary, in the case of a Material Defect in
any of the documents specified in clauses (ii) through (v), (vii), (viii) and (ix) in the definition
of “Mortgage File”, which Material Defect results solely from a delay in the return of the related documents from
the applicable filing or recording office and gives rise to a repurchase or substitution obligation on the part of the related
Mortgage Loan Seller with respect to the subject Mortgage Loan pursuant to the related Mortgage Loan Purchase Agreement, the Directing
Certificateholder, in its sole judgment, may (other than with respect to any Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class and, with respect to any other Mortgage Loan, only prior to the occurrence
and continuance of a Control Termination Event), and the Special Servicer may, in accordance with the Servicing Standard, after
the occurrence and during the continuance of a Control Termination Event, permit the related Mortgage Loan Seller in lieu of repurchasing
or substituting for the related Mortgage Loan, to deposit with the Master Servicer an amount, to be held in trust in a segregated
Eligible Account (which may be a sub-account of the Collection Account), equal to 25% of the Stated Principal Balance of the related
Mortgage Loan (in the alternative, the related Mortgage Loan Seller may deliver to the Master Servicer a letter of credit in such
amount, with a copy to the Custodian). Such funds or letter of credit, as applicable, shall be held by the Master Servicer (i)
until the date on which the Custodian determines and notifies the Master Servicer that such Material Defect has been cured or
the related Mortgage Loan is no longer part of the Trust Fund, at which time the Master Servicer shall return such funds (or letter
of credit) to the related Mortgage Loan Seller, or (ii) until same are applied to the Purchase Price (or the Substitution Shortfall
Amount, if applicable) as set forth below in this Section 2.02(d) in the event of a repurchase or substitution by the related
Mortgage Loan Seller. Notwithstanding the two (2) immediately preceding sentences, if the Master Servicer or the Special Servicer
certifies to the Trustee, the Certificate Administrator and the Custodian that it has determined in the exercise of its reasonable
judgment that the document with respect to which such Material Defect exists is

 

     -132-

     

    

 

required
in connection with an imminent enforcement of the mortgagee’s rights or remedies under the related Mortgage Loan, defending
any claim asserted by any Mortgagor or third party with respect to the related Mortgage Loan, establishing the validity or priority
of any lien on collateral securing the related Mortgage Loan or for any immediate significant servicing obligation, the related
Mortgage Loan Seller shall be required to repurchase or substitute for the related Mortgage Loan in accordance with, and to the
extent required by, the terms and conditions of Section 2.03(b) and Section 5 of the related Mortgage Loan Purchase Agreement;
provided, however, that such Mortgage Loan Seller shall not be required to repurchase the Mortgage Loan for a period
of ninety (90) days after receipt of a notice to repurchase (together with any applicable extension period) if it is attempting
to recover the document from the applicable filing or recording office and provides an officer’s certificate setting forth
what actions such Mortgage Loan Seller is pursuing in connection with such recovery. In the event of a repurchase or substitution,
upon the date of such repurchase or substitution, and in the event that the related Mortgage Loan Seller has delivered a letter
of credit to the Master Servicer in accordance with this Section 2.02(d), the Master Servicer shall, to the extent necessary,
draw on the letter of credit and deposit the proceeds of such draw, into the Collection Account to be applied to the Purchase
Price (or the Substitution Shortfall Amount, if applicable, in which event, the amount of such funds or proceeds that exceed the
Substitution Shortfall Amount shall be returned to the related Mortgage Loan Seller) in accordance with Section 2.03(b).
All such funds deposited in the Collection Account shall be invested in Permitted Investments, at the direction and for the benefit
of the related Mortgage Loan Seller. Such funds shall be treated as an “outside reserve fund” under the REMIC Provisions,
which, together with any reimbursement from the Lower-Tier REMIC, is beneficially owned by the related Mortgage Loan Seller for
federal income tax purposes, which Mortgage Loan Seller shall remain liable for any taxes payable on income or gain with respect
thereto.

 

(e)       It
is herein acknowledged that neither the Trustee nor any Custodian is under any duty or obligation (i) to determine whether any
of the documents specified in clauses (vi), (vii) and (xii) through (xviii) of the definition of “Mortgage
File” exist or are required to be delivered by the Depositor, the Mortgage Loan Sellers or any other Person (unless identified
on the Mortgage Loan Checklist) or (ii) to inspect, review or examine any of the documents, instruments, certificates or other
papers relating to the Mortgage Loans delivered to it to determine that the same are genuine, enforceable, duly authorized, sufficient
to perfect and maintain the perfection of a security interest or appropriate for the represented purpose or that they are other
than what they purport to be on their face and, with respect to the documents specified in clause (viii) of the definition
of the “Mortgage File”, whether the insurance is effective as of the date of the recordation, whether all endorsements
or riders issued are included in the file or if the policy has not been issued whether any acceptable replacement document has
been dated the date of the related Mortgage Loan funding. Further, with respect to the UCC Financing Statements referenced in
the Mortgage File, absent actual knowledge to the contrary or copies of UCC Financing Statements delivered to the Custodian as
part of the Mortgage File indicating otherwise, the Custodian may assume, for the purposes of the filings and the certification
to be delivered in accordance with this Section 2.02 that the related Mortgage File should include one (1) state level
UCC Financing Statement filing for each Mortgaged Property (or with respect to any Mortgage Loan that has two (2) or more Mortgagors,
for each Mortgagor, except to the extent multiple Mortgagors are named as debtors in the same UCC Financing Statement filing),
or if the Custodian has received notice that a particular UCC Financing

 

     -133-

     

    

 

Statement
was filed as a fixture filing, that the related Mortgage File should include only a local UCC Financing Statement filing for each
Mortgaged Property (or with respect to any Mortgage Loan that has two (2) or more Mortgagors, for each Mortgagor, except to the
extent multiple Mortgagors are named as debtors in the same UCC Financing Statement filing). The assignments of the UCC Financing
Statements to be assigned to the Trust will be delivered on the national forms (or on such other form as may be acceptable for
filing or recording in the applicable jurisdiction) and in a format suitable for filing or recording, as applicable, and will
be filed or recorded in the jurisdiction(s) where such UCC Financing Statements were originally filed or recorded, as indicated
in the documents provided, and in accordance with then-current laws.

 

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

 

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

 

Each
15Ga-1 Notice shall include (i) the identity of the related Mortgage Loan, (ii) the date the 15Ga-1 Repurchase Request is received
by the Repurchase Request Recipient or the date any withdrawal of the 15Ga-1 Repurchase Request is received by the Repurchase
Request Recipient, as applicable, (iii) if known, the basis for the 15Ga-1 Repurchase Request (as

 

     -134-

     

    

 

asserted
in the 15Ga-1 Repurchase Request), (iv) the identity of the Person making such 15Ga-1 Repurchase Request, and (v) a statement
from the Repurchase Request Recipient as to whether it currently plans to pursue such 15Ga-1 Repurchase Request.

 

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

 

In
the event that the Depositor, the Trustee, the Special Servicer, the Certificate Administrator, the Operating Advisor, the
Asset Representations Reviewer or the Custodian receives a 15Ga-1 Repurchase Request, such party shall promptly forward or
otherwise provide written notice of such 15Ga-1 Repurchase Request to the Master Servicer, if relating to a Non-Specially
Serviced Loan, or to the Special Servicer, if relating to a Specially Serviced Loan or REO Property, and include the
following statement in the related correspondence: “This is a ‘15Ga-1 Repurchase Request’ under Section
2.02 of the Pooling and Servicing Agreement relating to BANK 2017-BNK4, Commercial Mortgage Pass-Through Certificates,
Series 2017-BNK4 requiring action by you as the ‘Repurchase Request Recipient’ thereunder.” Upon receipt of
such 15Ga-1 Repurchase Request by the Master Servicer or the Special Servicer, as applicable, such party shall be deemed to
be the Repurchase Request Recipient in respect of such 15Ga-1 Repurchase Request, and such party shall comply with the
procedures set forth in this Section 2.02(g) with respect to such 15Ga-1 Repurchase Request. In no event shall the
Custodian, by virtue of this provision, be required to provide any notice other than as set forth in Section 2.02 of
this Agreement in connection with its review of the Mortgage File.

 

If
the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Custodian
receives notice or has knowledge of a withdrawal or a rejection of a 15Ga-1 Repurchase Request of which notice has been previously
received or given, and such notice was not received from or copied to the Master Servicer or the Special Servicer, then such party
shall give notice of such withdrawal or rejection to the Master Servicer or the Special Servicer, as applicable. Any such notice
received by the Trustee, the Certificate Administrator, the Certificate Registrar, Operating Advisor, Asset Representations Reviewer
or the Custodian shall also be provided to the Depositor and, in the case of a withdrawal notice, to the applicable Mortgage Loan
Seller.

 

In
the event that a Mortgage Loan is repurchased or replaced pursuant to Section 2.03 of this Agreement, the Special Servicer
shall promptly notify the Depositor of such repurchase or replacement.

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

 

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

 

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

 

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

 

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

 

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

 

(b)       After
receipt of a Repurchase Request, the Enforcing Servicer shall request in writing that the applicable Mortgage Loan Seller, not
later than ninety (90) days after

 

     -136-

     

    

 

(i)
except in the case of the succeeding clause (ii), the applicable Mortgage Loan Seller’s receipt of such notice of
such Repurchase Request or, if earlier, such Mortgage Loan Seller’s discovery of such Material Defect or (ii) in the case
of a Material Defect relating to a Mortgage Loan not being a “qualified mortgage” within the meaning of Section 860G(a)(3)
of the Code, but without regard to the rule of Treasury Regulations Section 1.860G-2(f)(2) that causes a defective Mortgage Loan
to be treated as a qualified mortgage, the earlier of (x) discovery by the related Mortgage Loan Seller or any party to this Agreement
of such Material Defect and (y) receipt of notice of the Material Defect from any party to this Agreement (such ninety (90) day
period, the “Initial Cure Period”), (A) cure such Material Defect in all material respects, at such Mortgage
Loan Seller’s own expense, including reimbursement of any related reasonable additional expenses of the Trust reasonably
incurred by any party to this Agreement, (B) repurchase the affected Mortgage Loan or REO Loan (excluding any related Serviced
Companion Loan, if applicable), at the applicable Purchase Price and in conformity with the applicable Mortgage Loan Purchase
Agreement and this Agreement or (C) substitute a Qualified Substitute Mortgage Loan (other than with respect to the Whole Loans,
for which no substitution will be permitted) for such affected Mortgage Loan or REO Loan (provided that in no event shall
any such substitution occur on or after the second anniversary of the Closing Date) and pay the Master Servicer for deposit into
the Collection Account, any Substitution Shortfall Amount in connection therewith and in conformity with the applicable Mortgage
Loan Purchase Agreement and this Agreement; provided, however, that except with respect to a Material Defect resulting
solely from the failure by the Mortgage Loan Seller to deliver to the Trustee or Custodian the actual policy of lender’s
title insurance required pursuant to clause (viii) of the definition of Mortgage File by a date not later than eighteen
(18) months following the Closing Date, if such Material Defect is capable of being cured but is not cured within the Initial
Cure Period, and the applicable Mortgage Loan Seller has commenced and is diligently proceeding with the cure of such Material
Defect within the Initial Cure Period, the applicable Mortgage Loan Seller shall have an additional ninety (90) days commencing
immediately upon the expiration of the Initial Cure Period (such additional ninety (90) day period, the “Extended Cure
Period”) to complete such cure (or, failing such cure, to repurchase the related Mortgage Loan or REO Loan (excluding
any related Serviced Companion Loan, if applicable) or substitute a Qualified Substitute Mortgage Loan (other than with respect
to the Whole Loans, for which no substitution will be permitted)); provided, further, that with respect to such
Extended Cure Period the applicable Mortgage Loan Seller shall have delivered an officer’s certificate to the Trustee, the
Certificate Administrator (who shall promptly deliver a copy of such officer’s certificate to the 17g-5 Information Provider),
the Master Servicer, the Special Servicer, the Operating Advisor and (with respect to any Mortgage Loan other than an Excluded
Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, prior to the occurrence
and continuance of a Consultation Termination Event) the Directing Certificateholder, setting forth the reason such Material Defect
is not capable of being cured within the Initial Cure Period and what actions the applicable Mortgage Loan Seller is pursuing
in connection with the cure thereof and stating that the applicable Mortgage Loan Seller anticipates that such Material Defect
will be cured within the Extended Cure Period; and provided, further, that, if any such Material Defect is not cured
after the Initial Cure Period and any such Extended Cure Period solely due to the failure of the related Mortgage Loan Seller
to have received the recorded document, then such Mortgage Loan Seller shall be entitled to continue to defer its cure, repurchase
and/or substitution obligations in respect of such Material

 

     -137-

     

    

 

Defect until eighteen (18) months after the Closing Date for so long
as such Mortgage Loan Seller certifies to the Trustee, the Master Servicer, the Special Servicer and the Certificate Administrator
no less than every ninety (90) days, beginning at the end of such Initial Cure Period, that such Material Defect is still in effect
solely because of its failure to have received the recorded document and that such Mortgage Loan Seller is diligently pursuing
the cure of such Material Defect (specifying the actions being taken). Notwithstanding the foregoing, any Defect or Breach which
causes any Mortgage Loan not to be a “qualified mortgage” (within the meaning of Section 860G(a)(3) of the Code, but
without regard to the rule of Treasury Regulations Section 1.860G-2(f)(2) that causes a defective Mortgage Loan to be treated
as 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 Defect or Breach during the Initial Cure Period) such Mortgage
Loan shall be repurchased or substituted for without regard to the Extended Cure Period described in the preceding sentence. If
the affected Mortgage Loan is to be repurchased, the funds in the amount of the Purchase Price remitted by the applicable Mortgage
Loan Seller are to be remitted by wire transfer to the Master Servicer for deposit into the Collection Account. In the event the
Special Servicer is required to enforce the Repurchase Request related to a Non-Specially Serviced Loan under this Section
2.03(b), within five (5) days of request by the Special Servicer, the Master Servicer shall deliver to the Special Servicer
a copy of the Servicing File with respect to any such Non-Specially Serviced Loan.

 

If
a Mortgage Loan Seller, in connection with a Material Defect (or an allegation of a Material Defect) pertaining to a Mortgage
Loan, makes a cash payment pursuant to an agreement or a settlement between the applicable Mortgage Loan Seller and the Special
Servicer on behalf of the Trust (and, for so long as no Control Termination Event has occurred and is continuing and in respect
of any Mortgage Loan that is not an Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority
of the Controlling Class, in either case, with the consent of the Directing Certificateholder or the Holder of the majority of
the Controlling Class, the consent of the Directing Certificateholder) (each such payment, a “Loss of Value Payment”)
with respect to such Mortgage Loan, the amount of such Loss of Value Payment shall be deposited into the Loss of Value Reserve
Fund to be applied in accordance with Section 3.05(g) of this Agreement. In connection with any Loss of Value Payment with
respect to any Non-Specially Serviced Loan, the Master Servicer shall promptly provide the Special Servicer, but in any event
within the time frames and in the manner provided in Section 3.19 (as if such Mortgage Loan were subject to a Servicing
Transfer Event), with the Servicing File and all information, documents and records relating to such Non-Specially Serviced Loan
and any related Serviced Companion Loan, either in the Master Servicer’s possession or otherwise reasonably available to
the Master Servicer, and reasonably required by the Special Servicer to permit the Special Servicer to calculate the Loss of Value
Payment, to the extent set forth in Section 3.19 (as if such Mortgage Loan were subject to a Servicing Transfer Event).
The Loss of Value Payment shall include the portion of any Liquidation Fees payable to the Special Servicer in respect of such
Loss of Value Payment and the portion of fees of the Asset Representations Reviewer attributable to the Asset Review of such Mortgage
Loan and not previously paid by the Mortgage Loan Seller. If such Loss of Value Payment is made, the Loss of Value Payment shall
serve as the sole remedy available to the Certificateholders and the Trustee on their behalf regarding any such Material Defect
in lieu of any obligation of the Mortgage Loan Seller to otherwise cure such Material Defect or repurchase or substitute for the

 

     -138-

     

    

 

affected
Mortgage Loan based on such Material Defect under any circumstances. This paragraph is intended to apply only to a mutual
agreement or settlement between the applicable Mortgage Loan Seller and the Special Servicer on behalf of the Trust, provided
that (i) prior to any such agreement or settlement nothing in this paragraph shall preclude the Mortgage Loan Seller or the
Special Servicer 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” within the meaning of Section 860G(a)(3) of the Code (but without regard to the rule of
Treasury Regulations Section 1.860G-2(f)(2) that causes a defective Mortgage Loan to be treated as a “qualified
mortgage”) may not be cured by a Loss of Value Payment.

 

If
any Breach that constitutes a Material Defect pertains to a representation or warranty that the related Mortgage Loan documents
or any particular Mortgage Loan document requires the related Mortgagor to bear the costs and expenses associated with any particular
action or matter under such Mortgage Loan document(s), then the related Mortgage Loan Seller shall cure such Breach within the
applicable cure period (as the same may be extended) by reimbursing the Trust (by wire transfer of immediately available funds)
for (i) the reasonable amount of any such costs and expenses incurred by the Master Servicer, the Special Servicer, the Certificate
Administrator, the Trustee or the Trust that are incurred as a result of such Breach and have not been reimbursed by the related
Mortgagor and (ii) the amount of any fees payable by the Mortgage Loan Seller to the Asset Representations Reviewer to the extent
not previously paid by the Mortgage Loan Seller to the Asset Representations Reviewer attributable to the Asset Review of such
Mortgage Loan; provided that in the event any such costs and expenses exceed $10,000, the Mortgage Loan Seller shall have the
option to either repurchase or substitute for the related Mortgage Loan as provided above or pay such costs and expenses. Except
as provided in the proviso to the immediately preceding sentence, the related Mortgage Loan Seller shall remit the amount of such
costs and expenses and, upon its making such remittance, the related Mortgage Loan Seller shall be deemed to have cured such Breach
in all respects. To the extent any fees or expenses that are the subject of a cure by the related Mortgage Loan Seller are subsequently
obtained from the related Mortgagor, the portion of the cure payment made by the related Mortgage Loan Seller equal to such fees
or expenses obtained from the related Mortgagor shall promptly be returned to the related Mortgage Loan Seller. Periodic Payments
due with respect to each Qualified Substitute Mortgage Loan (if any) after the related Due Date in the month of substitution,
and Periodic Payments due with respect to each Mortgage Loan being repurchased or replaced after the related Cut-off Date and
received by the Master Servicer or the Special Servicer on behalf of the Trust on or prior to the related date of repurchase or
substitution, shall be part of the Trust Fund. Periodic Payments due with respect to each Qualified Substitute Mortgage Loan (if
any) on or prior to the related Due Date in the month of substitution, and Periodic Payments due with respect to each Mortgage
Loan being repurchased or replaced and received by the Master Servicer or the Special Servicer on behalf of the Trust after the
related date of repurchase or substitution, shall not be part of the Trust Fund and are to be remitted by the Master Servicer
or the Special Servicer to the applicable Mortgage Loan Seller effecting the related repurchase or substitution promptly following
receipt. Notwithstanding anything contained in this Agreement or the related Mortgage Loan Purchase

 

     -139-

     

    

 

Agreement,
a delay in either the discovery of a Material Defect or in providing notice of such Material Defect shall relieve the applicable
Mortgage Loan Seller of its obligation to cure, repurchase or substitute for the related Mortgage Loan if (i) the related Mortgage
Loan Seller did not otherwise discover or have knowledge of such Material Defect, (ii) such delay is a result of the failure by
a party to the applicable Mortgage Loan Purchase Agreement, or this Agreement, to provide prompt notice as required by the terms
of the applicable Mortgage Loan Purchase Agreement, or this Agreement, after such party has actual knowledge of such Material
Defect (knowledge shall not be deemed to exist by reason of the Custodial Exception Report or possession of the Mortgage File)
(iii) such delay precludes such Mortgage Loan Seller from curing such Material Defect and (iv) such Material Defect does not relate
to the applicable Mortgage Loan not being a “qualified mortgage” within the meaning of Code Section 860G(a)(3), but
without regard to the rule of Treasury regulations Section 1.860G-2(f)(2) that causes a defective obligation to be treated as
a qualified mortgage. Notwithstanding the foregoing, if a Mortgage Loan is not secured by a Mortgaged Property that is, in whole
or in part, a hotel, restaurant (operated by a borrower), healthcare facility, nursing home, assisted living facility, self-storage
facility, theater or fitness center (operated by a borrower), then the failure to deliver copies of the UCC Financing Statements
with respect to such Mortgage Loan shall not be a Material Defect.

 

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

 

(c)       Subject
to the applicable Mortgage Loan Seller’s right to cure as contemplated above in this Section 2.03, and further subject
to Section 2.01(b) and Section 2.01(c), any of the following shall cause a document in the Mortgage File to be deemed
to have a Material Defect: (a) the absence from the Mortgage File of the original signed Mortgage Note, unless the Mortgage File
contains a signed lost note affidavit and indemnity with a copy of the Mortgage Note that appears to be regular on its face; (b)
the absence from the Mortgage File of the original signed Mortgage that appears to be regular on its face, unless there is included
in the Mortgage File either a copy of the Mortgage with evidence of recording thereon or a copy of the Mortgage and a certificate
from the related Mortgage Loan Seller stating that the original signed Mortgage was sent for recordation; (c) the absence from
the Mortgage File of the item called for by clause (viii) of the definition of Mortgage File; (d) the absence from the
Mortgage File of any intervening assignments required to create a complete chain of assignments to the Trustee on behalf of the
Trust, unless there is included in the Mortgage File either a copy of the assignment with evidence of recording thereon or a copy
of the intervening assignment and a certificate from the related Mortgage Loan Seller stating that the original intervening assignments
were sent for filing or recordation, as applicable; (e) the absence from

 

     -140-

     

    

 

the
Mortgage File of any required letter of credit; or (f) with respect to any related leasehold Mortgage Loan, the absence from the
related Mortgage File of a copy (or an original, if available) of the related Ground Lease; provided, however, that
no Defect (except the Defects previously described in sub-clauses (a) through (f) of this Section 2.03(c))
shall be considered to materially and adversely affect the value of the related Mortgage Loan, the value of the related Mortgaged
Property or the interests of the Trustee or Certificateholders unless the document with respect to which the Defect exists is
required in connection with an imminent enforcement of the mortgagee’s rights or remedies under the related Mortgage Loan,
defending any claim asserted by any Mortgagor or third party with respect to the related Mortgage Loan, establishing the validity
or priority of any lien on any collateral securing the related Mortgage Loan or for any immediate significant servicing obligation;
provided, further, that no Defect relating to any Non-Serviced Mortgage Loan previously described in sub-clauses
(b) through (f) of this Section 2.03(c) shall be considered to materially and adversely affect the value of
such Mortgage Loan, the value of the related Mortgaged Property or the interests of the Trustee or Certificateholders unless the
related Mortgage Loan Seller, after receipt of notice of such Defect, is unable to produce a copy of the document with respect
to which the Defect exists within a reasonable period after receiving such notice or otherwise establish that the original or
copy, as applicable, of such document has been delivered, in compliance with the terms of the related Non-Serviced PSA, to the
custodian under the related Non-Serviced PSA. Notwithstanding the foregoing, the delivery of executed escrow instructions or a
binding commitment to issue a lender’s title insurance policy, as provided in clause (viii) of the definition of
Mortgage File herein, in lieu of the delivery of the actual policy of lender’s title insurance, shall not be considered
a Material Defect with respect to any Mortgage File if such actual policy is delivered to the Custodian not later than eighteen
(18) months following the Closing Date. Notwithstanding the foregoing, to the extent a Mortgage Loan Seller has otherwise complied
with its document delivery requirements under this Agreement and the related Mortgage Loan Purchase Agreement, in the event that
the Custodian has acknowledged receipt pursuant to Section 2.02 above of a document that is part of the Mortgage File or
a Mortgage Loan Seller can otherwise prove delivery of the document, and the Custodian subsequently loses a document, the fact
that such document is lost may not be utilized as the basis for a claim of a Material Defect against a Mortgage Loan Seller pursuant
to Section 5(a) of the related Mortgage Loan Purchase Agreement and/or this Section 2.03 and the Custodian shall be liable
for any such loss to the extent provided for in Section 8.01.

 

(d)       In
connection with any repurchase of, or substitution of a Qualified Substitute Mortgage Loan for a Mortgage Loan contemplated by
this Section 2.03, the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer
shall each tender to the applicable Mortgage Loan Seller, upon delivery to each of the Trustee, the Certificate Administrator,
the Custodian, the Master Servicer and the Special Servicer of a trust receipt executed by the applicable Mortgage Loan Seller
evidencing such repurchase or substitution, all portions of the Mortgage File and other documents pertaining to such Mortgage
Loan possessed by each of the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer
(other than attorney-client communications that are privileged communications), and each document that constitutes a part of the
Mortgage File that was endorsed or assigned to the Trustee shall be endorsed or assigned, as the case may be to the applicable
Mortgage Loan Seller in the same manner as provided in Section 5 of the related Mortgage Loan Purchase Agreement and, if applicable,
the definition of “Mortgage File” herein,

 

     -141-

     

    

 

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
5 of each of the Mortgage Loan Purchase Agreements and the provisions of this Section 2.03 provide the sole remedy available to
the Certificateholders (subject to the limitations on the rights of the Certificateholders under this Agreement), or the Trustee
on behalf of the Certificateholders, the Master Servicer or the Special Servicer, with respect to any Material Defect.

 

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

 

(g)       If
a Mortgage Loan Seller incurs any expense in connection with the curing of a Breach that constitutes a Material Defect, which
also constitutes a default under the related Mortgage Loan and is reimbursable thereunder, such Mortgage Loan Seller shall have
a right, and shall be subrogated to the rights of the Trustee and the Trust under the Mortgage Loan to recover the amount of such
expenses from the related Mortgagor; provided, however, that such Mortgage Loan Seller’s rights pursuant to
this Section 2.03(g) shall be junior, subject and subordinate to the rights of the Trustee, the Certificate Administrator,
the Trust, the Master Servicer and the Special Servicer to recover amounts owed by the related Mortgagor under the terms of such
Mortgage Loan including, without limitation, the rights to recover unreimbursed Advances, accrued and unpaid interest on Advances
at the Reimbursement Rate, fees owed to the Master Servicer or the Special Servicer, and unpaid or unreimbursed expenses of the
Trustee, the Certificate Administrator, the Trust, the Master Servicer or the Special Servicer allocable to such Mortgage Loan.
The Enforcing Servicer shall use reasonable efforts to recover such expenses for such Mortgage Loan Seller to the extent consistent
with the Servicing Standard, but taking into account the subordinate nature of the reimbursement to the related Mortgage Loan
Seller; provided, however, that the Enforcing Servicer determines in the exercise of its sole discretion consistent
with the Servicing Standard that such actions by it will not impair the Enforcing

 

     -142-

     

    

 

Servicer’s
collection or recovery of principal, interest and other sums due with respect to the related Mortgage Loan that would otherwise
be payable to the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator and the Certificateholders
pursuant to the terms of this Agreement; provided, further, that the Special Servicer may waive the collection of
amounts due on behalf of such Mortgage Loan Seller in its sole discretion in accordance with the Servicing Standard.

 

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

 

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

 

(j)       With
respect to any Crossed Underlying Loan, to the extent that the applicable Mortgage Loan Seller is required to repurchase or substitute
for such Crossed Underlying Loan in the manner prescribed in Section 2.03(h) or Section 2.03(i) while the Trustee
continues to hold any other Crossed Underlying Loans in the related Crossed Mortgage Loan Group, the applicable Mortgage Loan
Seller and the Enforcing Servicer, on behalf of the Trustee, as assignee of the Depositor, will, as set forth in the related Mortgage
Loan Purchase Agreement, forbear from enforcing any remedies against the other’s Primary Collateral but each will be

 

     -143-

     

    

 

permitted
to exercise remedies against the Primary Collateral securing its respective related Mortgage Loans, including with respect to
the Trustee, the Primary Collateral securing the Mortgage Loans still held by the Trustee, so long as such exercise does not materially
impair the ability of the other party to exercise its remedies against its Primary Collateral. If the exercise of the remedies
by one party would materially impair the ability of the other party to exercise its remedies with respect to the Primary Collateral
securing the Crossed Underlying Loans held by such party, then both parties have agreed in the related Mortgage Loan Purchase
Agreement to forbear from exercising such remedies until the Mortgage Loan documents evidencing and securing the relevant Mortgage
Loan can be modified in a manner that complies with the related Mortgage Loan Purchase Agreement to remove the threat of material
impairment as a result of the exercise of remedies.

 

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

 

(ii)       In
the event that the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Operating
Advisor (solely in its capacity as operating advisor) or the Directing Certificateholder identifies a Material Defect with respect
to a Mortgage Loan (without implying any duty of such person to make, or to attempt to make, such a discovery), that party shall
deliver prompt written notice of such Material Defect to each other party to this Agreement and the related Mortgage Loan Seller
identifying the applicable Mortgage Loan and setting forth the basis for such allegation (a “PSA Party Repurchase Request”
and each of a Certificateholder Repurchase Request or a PSA Party Repurchase Request, the “Repurchase Request”)
and the Enforcing Servicer shall promptly send the PSA Party Repurchase Request to the related Mortgage Loan Seller. The Enforcing
Servicer shall act as the Enforcing Party and enforce the rights of the Trust against the related Mortgage Loan Seller with respect
to a PSA Party Repurchase Request.

 

(iii)       In
the event the Repurchase Request is not Resolved within one hundred-eighty (180) days after the Mortgage Loan Seller receives
the Repurchase Request (a “Resolution Failure”), then the provisions described in Section 2.03(l) below
shall apply. Receipt of the Repurchase Request shall be deemed to occur two (2) Business Days after the Repurchase Request
is sent to the related Mortgage Loan Seller. A Resolved Repurchase Request shall not preclude the Special Servicer from exercising
any of its rights related to a Material Defect in the manner and timing otherwise set forth in this Agreement, in the related
Mortgage Loan Purchase Agreement or as provided by law.

 

(l)        (i)After
a Resolution Failure occurs with respect to a Repurchase Request regarding a Mortgage Loan (whether the Repurchase Request was
initiated by an Initial

Requesting
Certificateholder, a party to this Agreement or the Directing Certificateholder), the Enforcing Servicer shall send a notice (a
“Proposed Course of Action Notice”) to the Initial Requesting Certificateholder, if any, to the address specified
in the Initial Requesting Certificateholder’s Repurchase Request, and to the Certificate Administrator (which shall be delivered
via electronic mail to trustadministrationgroup@wellsfargo.com) who shall make such notice available to all other Certificateholders
and Certificate Owners by posting such notice on the Certificate Administrator’s Website indicating the Enforcing Servicer’s
intended course of action with respect to the Repurchase Request (a “Proposed Course of Action”). Such notice
shall include (a) a request to Certificateholders to indicate their agreement with or dissent from such Proposed Course of Action
by clearly marking “agree” or “disagree” to the Proposed Course of Action on such notice within 30 days
of the date of such notice and a disclaimer that responses received after such 30-day period will not be taken into consideration,
(b) a statement that in the event any Certificateholder disagrees with the Proposed Course of Action, the Enforcing Servicer (either
as the Enforcing Party or as the Enforcing Servicer in circumstances where a Certificateholder is acting as the Enforcing Party)
shall be compelled to follow the course of action agreed to and/or proposed by the majority of the responding Certificateholders
that involves referring the matter to mediation or arbitration, as the case may be, (c) a statement that responding Certificateholders
will be required to certify their holdings in connection with such response, (d) a statement that only responses clearly marked
“agree” or “disagree” with such Proposed Course of Action will be taken into consideration and (e) instructions
for responding Certificateholders to send their responses to the Enforcing Servicer and the Certificate Administrator. The Certificate
Administrator shall, within three (3) Business Days after the expiration of the 30-day response period, tabulate the responses
received from the Certificateholders and share the results with the Enforcing Servicer. The Certificate Administrator shall only
count responses timely received that clearly indicate agreement or dissent with the related Proposed Course of Action and additional
verbiage or qualifying language shall not be taken into consideration for purposes of determining whether the related Certificateholder
agrees or disagrees with the Proposed Course of Action. The Certificate Administrator shall be under no obligation to answer any
questions from Certificateholders regarding such Proposed Course of Action. For the avoidance of doubt, the Certificate Administrator’s
obligations in connection with this Section 2.03(l) shall be limited solely to tabulating Certificateholder responses of
“agree” or “disagree” to the Proposed Course of Action, and such obligation shall not be construed to
impose any enforcement obligation on the Certificate Administrator. The Enforcing Servicer may conclusively rely (without investigation)
on the Certificate Administrator’s tabulation of the responses of the responding Certificateholders and whether that amount
constitutes a majority. If (a) the Enforcing Servicer’s intended course of action with respect to the Repurchase Request
does not involve pursuing further action to exercise rights against the related Mortgage Loan Seller with respect to the Repurchase
Request and the Initial Requesting Certificateholder, if any, or any other Certificateholder or Certificate Owner wishes to exercise
its right to refer the matter to mediation (including nonbinding arbitration) or arbitration, or (b) the Enforcing Servicer’s
intended course of action is to pursue further action to exercise rights against the applicable Mortgage Loan Seller with respect
to the Repurchase Request but the Initial Requesting Certificateholder, if any, or any other Certificateholder (other than the
holder of the RR Interest) 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

 

     -145-

     

    

 

may deliver to the
Enforcing Servicer a written notice (a “Preliminary Dispute Resolution Election Notice”) within thirty (30)
days from the date the Proposed Course of Action Notice is posted on the Certificate Administrator’s Website (the “Dispute
Resolution Cut-off Date”) indicating its intent to exercise its right to refer the matter to either mediation or arbitration.
In the event any Certificateholder or Certificate Owner entitled to do so delivers a Preliminary Dispute Resolution Election Notice,
and the Enforcing Servicer has also received responses from other Certificateholders or Certificate Owners supporting the Enforcing
Servicer’s initial Proposed Course of Action, such responses will be considered Preliminary Dispute Resolution Election
Notices supporting the Proposed Course of Action for purposes of determining the course of action approved by the majority of
Certificateholders.

 

(ii)       If
neither the Initial Requesting Certificateholder, if any, nor any other Certificateholder or Certificate Owner entitled to do
so delivers a Preliminary Dispute Resolution Election Notice prior to the Dispute Resolution Cut-off Date, no Certificateholder
or Certificate Owner otherwise entitled to do so shall have the right to refer the Repurchase Request to mediation or arbitration,
and the Enforcing Servicer shall be the sole party entitled to determine a course of action, including, but not limited to, enforcing
the Trust’s rights against the related Mortgage Loan Seller, subject to any consent or consultation rights of the Directing
Certificateholder pursuant to Section 6.08.

 

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

 

(iv)       If,
following the Dispute Resolution Consultation, no Requesting Certificateholder timely delivers a Final Dispute Resolution Election
Notice to the Enforcing Servicer, then the Enforcing Servicer will continue to act as the Enforcing Party and will remain obligated
under this Agreement to determine a course of action including, but not limited to, enforcing the rights of the Trust with respect
to the Repurchase Request and no Certificateholder or Certificate Owner shall have any further right to elect to refer the matter
to mediation or arbitration.

 

     -146-

     

    

 

(v)       If
a Requesting Certificateholder timely delivers a Final Dispute Resolution Election Notice to the Enforcing Servicer, then such
Requesting Certificateholder shall become the Enforcing Party and must promptly submit the matter to mediation (including nonbinding
arbitration) or arbitration. If there are more than one Requesting Certificateholder that timely deliver a Final Dispute Resolution
Election Notice, then such Requesting Certificateholders shall collectively become the Enforcing Party, and the holder or holders
of a majority of the Voting Rights among such Requesting Certificateholders shall be entitled to make all decisions relating to
such mediation or arbitration. If, however, no Requesting Certificateholder commences arbitration or mediation pursuant to the
terms of this Agreement within thirty (30) days after delivery of its Final Dispute Resolution Election Notice to the Enforcing
Servicer, then (i) the rights of a Requesting Certificateholder to act as the Enforcing Party shall terminate and no Certificateholder
or Certificate Owner shall have any further right to elect to refer the matter to mediation or arbitration, (ii) if the Proposed
Course of Action Notice indicated that the Enforcing Servicer shall take no further action with respect to the Repurchase Request,
then the related Material Defect shall be deemed waived for all purposes under this Agreement and the related Mortgage Loan Purchase
Agreement; provided, however, that such Material Defect shall not be deemed waived with respect to a Requesting
Certificateholder, any other Certificateholder or Certificate Owner or the Enforcing Servicer to the extent there is a material
change in the facts and circumstances known to such party at the time when the Proposed Course of Action Notice is posted on the
Certificate Administrator’s Website, and (iii) if the Proposed Course of Action Notice had indicated a course of action
other than the course of action under clause (ii), then the Enforcing Servicer shall again become the Enforcing Party and,
as such, shall be the sole party entitled to enforce the Trust’s rights against the related Mortgage Loan Seller.

 

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

 

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

 

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

 

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

 

     -147-

     

    

 

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

 

(i)         The
mediation shall be administered by a nationally recognized mediation services provider selected by the related Mortgage Loan Seller
within thirty (30) days of receipt of written notice of the Enforcing Party’s selection of mediation (such provider, the
“Mediation Services Provider”) in accordance with published mediation procedures (the “Mediation Rules”)
promulgated by the Mediation Services Provider.

 

(ii)        The
mediator shall be impartial, an attorney admitted to practice in the state of New York and have at least fifteen (15) years of
experience in commercial litigation, and if possible, commercial real estate finance or commercial mortgage-backed securitization
matters and who will be appointed from a list of neutrals maintained by the Mediation Services Provider. Upon being supplied a
list of at least ten (10) potential qualified mediators by the Mediation Services Provider each party will have the right to exercise
two (2) peremptory challenges within fourteen (14) days and to rank the remaining potential mediators in order of preference.
The Mediation Services Provider shall select the mediator from the remaining attorneys on the list respecting the preference choices
of the parties to the extent possible.

 

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

 

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

 

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

 

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

 

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

 

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

 

(ii)        The
arbitrator shall be impartial, an attorney admitted to practice in the State of New York and have at least fifteen (15) years
of experience in commercial litigation, and if possible, commercial real estate finance or commercial mortgage-backed

 

     -148-

     

    

 

securitization
matters and who will be appointed from a list of neutrals maintained by the Arbitration Services Provider. Upon being supplied
a list of at least ten (10) potential arbitrators by the Arbitration Services Provider each party will have the right to exercise
two (2) peremptory challenges within fourteen (14) days and to rank the remaining potential arbitrators in order of preference.
The Arbitration Services Provider will select the arbitrator from the remaining attorneys on the list respecting the preference
choices of the parties to the extent possible.

 

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

 

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

 

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

 

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

 

     -149-

     

    

 

the arbitrator shall be final and non-appealable, except for actions to confirm or vacate the determination
permitted under federal or state law, and may be enforced in any court of competent jurisdiction.

 

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

 

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

 

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

 

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

 

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

 

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

 

(iv)       In
the event a Requesting Certificateholder is the Enforcing Party, the agreement with the arbitrator or mediator, as the case may
be, shall be required to contain an acknowledgment that the Trust, or the Enforcing Servicer on its behalf, shall be a party to
any arbitration or mediation proceedings solely for the purpose of being the beneficiary of any award in favor of the Enforcing
Party; provided that the degree and

 

     -150-

     

    

 

extent to which the Enforcing Servicer actively prepares for and participates in such
proceeding shall be determined by such Enforcing Servicer in consultation with the Directing Certificateholder (provided
that a Consultation Termination Event has not occurred and is not continuing) and in accordance with the Servicing Standard. All
amounts recovered by the Enforcing Party shall be paid to the Trust, or the Enforcing Servicer on its behalf, and deposited in
the Collection Account. The agreement with the arbitrator or mediator, as the case may be, shall provide that in the event a Requesting
Certificateholder is allocated any related costs and expenses pursuant to the terms of the arbitrator’s decision or the
agreement reached in mediation, neither the Trust nor the Enforcing Servicer acting on its behalf shall be responsible for any
such costs and expenses allocated to the Requesting Certificateholder.

 

(v)        In
the event a Requesting Certificateholder is the Enforcing Party, the Requesting Certificateholder is required to pay any expenses
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 Trustee or the Enforcing Servicer, 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 (A) the
Certificateholders shall be permitted to communicate prior to the commencement of any such proceedings to the extent provided
in Section 5.06 and (B) the Enforcing Servicer shall be permitted to include such information in any 15Ga-1 Notice as it
is required pursuant to Section 2.02(g).

 

(vii)      For
the avoidance of doubt, in no event shall the exercise of any right of a Requesting Certificateholder to refer a Repurchase Request
to mediation or arbitration or participation in such mediation or arbitration affect in any manner the ability of the Enforcing
Servicer to perform its obligations with respect to a Mortgage Loan (including without limitation, a liquidation, foreclosure,
negotiation of a loan modification or workout, acceptance of a discounted pay off or deed in lieu, or bankruptcy or other litigation)
or the exercise of any rights of a Directing Certificateholder.

 

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

 

(ix)       Any
out-of-pocket expenses required to be borne by or allocated to the Enforcing Servicer in a mediation or arbitration or related
responsibilities pursuant to this Agreement shall be reimbursable as additional Trust Fund expenses.

limiting the foregoing, subject to Section 3.19, the Special Servicer shall be obligated to service and administer (i)
any Mortgage Loans (other than the Non-Serviced Mortgage Loans) and any related Serviced Companion Loans as to which a Servicing
Transfer Event has occurred and is continuing (each, a “Specially Serviced Loan”) or as otherwise provided
herein with respect to Non-Specially Serviced Loans in connection with any Major Decision or Special Servicer Decision and (ii)
any REO Properties (other than the Non-Serviced Mortgaged Properties); provided that the Master Servicer shall continue
to receive payments and make all calculations, and prepare, or cause to be prepared, all reports, required hereunder with respect
to the Specially Serviced Loans, except for the reports specified herein as prepared by the Special Servicer, as if no Servicing
Transfer Event had occurred and with respect to the REO Properties (and the related REO Loans) as if no REO Acquisition had occurred,
and to render such services with respect to such Specially Serviced Loans and REO Properties as are specifically provided for
herein; provided, further, however, that the Master Servicer shall not be liable for failure to comply with
such duties insofar as such failure results from a failure of the Special Servicer to provide sufficient information to the Master
Servicer to comply with such duties or failure by the Special Servicer to otherwise comply with its obligations hereunder. The
Master Servicer, in its capacity as Master Servicer, shall not have any responsibility for the performance by the Special Servicer,
in its capacity as Special Servicer, of its duties under this Agreement. The Special Servicer, in its capacity as Special Servicer,
shall not have any responsibility for the performance by the Master Servicer, in its capacity as Master Servicer, of its duties
under this Agreement. Each Mortgage Loan or any related Serviced Companion Loan that becomes a Specially Serviced Loan shall continue
as such until satisfaction of the conditions specified in Section 3.19(a). Without limiting the foregoing, subject to Section
3.19 and in accordance with the terms of this Agreement, the Master Servicer shall be obligated to service and administer
any Non-Specially Serviced Loan or any related Serviced Companion Loan. The Special Servicer shall make the property inspections,
use its reasonable efforts to collect the financial statements, budgets, operating statements and rent rolls and forward to the
Master Servicer the reports in respect of the related Mortgaged Properties with respect to Specially Serviced Loans in accordance
with Section 3.12. After notification to the Master Servicer, the Special Servicer may contact the Mortgagor of any Non-Specially
Serviced Loan if efforts by the Master Servicer to collect required financial information have been unsuccessful or any other
issues remain unresolved. Such contact shall be coordinated through and with the cooperation of the Master Servicer. No provision
herein contained shall be construed as an express or implied guarantee by the Master Servicer or the Special Servicer of the collectability
or recoverability of payments on the Mortgage Loans or any related Serviced Companion Loan or be construed to impair or adversely
affect any rights or benefits provided by this Agreement to the Master Servicer or the Special Servicer (including with respect
to Servicing Fees, Special Servicing Fees

 

     -154-

     

    

 

or
the right to be reimbursed for Advances and interest accrued thereon). Any provision in this Agreement for any Advance by the
Master Servicer or the Trustee is intended solely to provide liquidity for the benefit of the Certificateholders and not as credit
support or otherwise to impose on any such Person the risk of loss with respect to one or more of the Mortgage Loans or any related
Serviced Companion Loans. No provision hereof shall be construed to impose liability on the Master Servicer or the Special Servicer
for the reason that any recovery to the Certificateholders in respect of a Mortgage Loan at any time after a determination of
present value recovery is less than the amount reflected in such determination.

 

(b)       Subject
only to the Servicing Standard and the terms of this Agreement (including, without limitation, Section 6.08) and of the
respective Mortgage Loans, any related Serviced Companion Loans and any related Intercreditor Agreement, if applicable, and applicable
law, each of the Master Servicer and the Special Servicer shall have full power and authority, acting alone or, subject to Section
3.20, through one or more Sub-Servicers, to do or cause to be done any and all things in connection with such servicing and
administration for which it is responsible which it may deem necessary or desirable. Without limiting the generality of the foregoing,
each of the Master Servicer and the Special Servicer (with respect to (x) Special Servicer Decisions and Major Decisions on the
Mortgage Loans and (y) the Specially Serviced Loans and REO Properties), in its own name (or in the name of the Trustee and, if
applicable, the related Serviced Companion Noteholder), is hereby authorized and empowered by the Trustee to execute and deliver,
on behalf of the Certificateholders (and, with respect to a Serviced Companion Loan, the related Serviced Companion Noteholder)
and the Trustee or any of them, with respect to each Mortgage Loan and any related Serviced Companion Loan it is obligated to
service under this Agreement: (i) any and all financing statements, continuation statements and other documents or instruments
necessary to maintain the lien created by the related Mortgage or other security document in the related Mortgage File on the
related Mortgaged Property and related collateral, and shall, from time to time, execute and/or deliver such financing statements,
continuation statements and other documents or instruments as necessary to maintain the lien created by the related Mortgage or
other security document in the related Mortgage File on the related Mortgaged Property and related collateral; (ii) subject to
Sections 3.08, 3.18 and 6.08, any and all modifications, waivers, amendments or consents to, under or with
respect to any documents contained in the related Mortgage File; (iii) any and all instruments of satisfaction or cancellation,
pledge agreements and other documents in connection with a defeasance, or of partial or full release or discharge, and all other
comparable instruments; and (iv) any or all complaints or other pleadings to initiate and/or to terminate any action, suit or
proceeding on behalf of the Trust (in their representative capacities (except as set forth below in this paragraph). The Master
Servicer (with respect to Non-Specially Serviced Loans) and the Special Servicer (with respect to Specially Serviced Loans) shall
provide to the Mortgagor related to such Mortgage Loans that it is servicing any reports required to be provided to them pursuant
to the related Mortgage Loan documents. Subject to Section 3.10, the Trustee shall (i) on the Closing Date, furnish to
the Master Servicer and the Special Servicer original powers of attorney in the form of Exhibit R-1 or Exhibit R-2
attached hereto, as applicable (or such other form as mutually agreed to by the Trustee and the Master Servicer or the Special
Servicer, as applicable) and (ii) upon request, furnish, or cause to be furnished, to the Master Servicer or the Special Servicer
any powers of attorney substantially in the form of Exhibit R-1 or Exhibit R-2 attached hereto, as applicable (or
such other form as mutually agreed to by the Trustee and the Master Servicer or the Special Servicer, as applicable) and other
documents necessary or

 

     -155-

     

    

 

appropriate
to enable the Master Servicer or the Special Servicer, as the case may be, to carry out its servicing and administrative duties
hereunder; provided, however, that the Trustee shall not be held responsible or liable for any acts of the Master
Servicer or the Special Servicer, or for any negligence with respect to, or misuse of, any such power of attorney by the Master
Servicer or the Special Servicer. Notwithstanding anything contained herein to the contrary, the Master Servicer or the Special
Servicer, as the case may be, shall not, without the Trustee’s written consent: (i) initiate any action, suit or proceeding
solely under the Trustee’s name without indicating the Master Servicer’s or the Special Servicer’s, as the case
may be, representative capacity (unless prohibited by any requirement of the applicable jurisdiction in which any such action,
suit or proceeding is brought and if so prohibited, in the manner required by such jurisdiction (provided that the Master
Servicer or the Special Servicer, as applicable, shall then provide five (5) Business Days’ written notice to the Trustee
of the initiation of such action, suit or proceeding (or such shorter time period as is reasonably required in the judgment of
the Master Servicer or the Special Servicer, as applicable, made in accordance with the Servicing Standard) prior to filing such
action, suit or proceeding, and shall not be required to obtain the Trustee’s consent or indicate the Master Servicer’s
or the Special Servicer’s, as applicable, representative capacity)) or (ii) take any action with the intent to cause, and
that actually causes, the Trustee to be required to be registered to do business in any state.

 

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

 

     -156-

     

    

 

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

 

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

 

(f)         Within
sixty (60) days (or such shorter time period as is required by the terms of the applicable Mortgage Loan documents) after the
later of (i) the receipt thereof by the Master Servicer and (ii) the Closing Date, the Master Servicer shall notify each lessor
under a Ground Lease for each Mortgage Loan identified as subject to a leasehold interest on the Mortgage Loan Schedule, that
the Trust is the leasehold mortgagee and that the Master Servicer or the Special Servicer shall service the related Mortgage Loan
for the benefit of the Certificateholders. The costs and expenses of any modifications to Ground Leases shall be paid by the related
Mortgagor.

 

With
respect to letters of credit delivered in accordance with subclause (B) of clause (xii) of the definition of “Mortgage
File”, (a) within sixty (60) days of the Closing Date or such shorter period as is required by the terms of such letter
of credit or other applicable Mortgage Loan documents, the related Mortgage Loan Seller shall notify the bank issuing the letter
of credit that the Master Servicer on behalf of the Trustee shall be the beneficiary under such letter of credit, and (b) within
sixty (60) days of the Closing Date, the Master Servicer shall present such letter of credit and the related assignment documentation
delivered by the Mortgage Loan Seller in accordance with such subclause of the definition of “Mortgage File” to the
letter of credit bank issuing such letter of credit and request that such letter of credit bank reissue the letter of credit in
the name of “Wells Fargo Bank, National Association, as Master Servicer, on behalf of Wilmington Trust, National Association,
as Trustee, for the benefit of registered holders of BANK 2017-BNK4, Commercial Mortgage Pass-Through Certificates, Series 2017-BNK4”.
The Master Servicer shall otherwise use reasonable efforts to obtain such reissued letter of credit back from the issuing letter
of credit bank within sixty (60) days (and in any event within ninety (90) days) following the Closing Date. The related Mortgage
Loan Seller shall provide such reasonable cooperation as requested by the Master Servicer, including without limitation by delivering
such additional assignment or amendment documents required by the issuing bank in order to reissue a letter of credit as provided
above.

 

If
a letter of credit is required to be drawn upon earlier than the date that the letter of credit has been revised as contemplated
in the preceding sentence, such Mortgage Loan Seller shall cooperate with the reasonable requests of the Master Servicer or Special
Servicer in connection with making a draw under such letter of credit. If the Mortgage Loan documents do not require the related
Mortgagor to pay any costs and expenses relating to any modifications to or assignment of the related letter of credit, then the
applicable Mortgage Loan Seller shall pay such costs and expenses as and to the extent required under the applicable Mortgage
Loan Purchase Agreement. If the Mortgage Loan documents require the related Mortgagor to pay any costs and expenses relating to
any modifications to the related letter of credit, and such Mortgagor fails to pay such costs and expenses after the Master Servicer
has exercised reasonable efforts to collect such costs and expenses from such Mortgagor, then the Master

 

     -157-

     

    

 

Servicer
shall give the applicable Mortgage Loan Seller notice of such failure and the amount of costs and expenses, and such Mortgage
Loan Seller shall pay such costs and expenses as and to the extent required under the applicable Mortgage Loan Purchase Agreement.
The costs and expenses of any modifications to Ground Leases shall be paid by the related Mortgagor. Neither the Master Servicer
nor the Special Servicer shall have any liability for the failure of any Mortgage Loan Seller to perform its obligations under
the related Mortgage Loan Purchase Agreement.

 

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

 

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

 

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

 

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

 

     -158-

     

    

 

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

 

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

 

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

 

     -159-

     

    

 

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. In the event of any conflict between this Agreement and the related Intercreditor Agreement,
the provisions of the related Intercreditor Agreement shall control.

 

(n)       [RESERVED.]

 

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

 

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

 

Section
3.02     Collection of Mortgage Loan Payments. (a) The Master Servicer and the Special
Servicer shall each make reasonable efforts to collect all payments called for under the terms and provisions of the Mortgage
Loans (other than the Non-Serviced Mortgage Loans) and the Serviced Companion Loans it is obligated to service hereunder, and
shall follow such collection procedures as are consistent with this Agreement (including, without limitation, the Servicing
Standard); provided that with respect to each Mortgage Loan that has an Anticipated Repayment Date, for so long as the
related Mortgagor is in compliance with each provision of the related Mortgage Loan documents, the Master Servicer and the
Special Servicer

 

     -160-

     

    

 

shall
be permitted to take any enforcement action with respect to the failure of the related Mortgagor to make any payment of Excess
Interest to the extent permitted under the related Mortgage Loan documents; provided, further, that the Master Servicer
or the Special Servicer, as the case may be, may take action to enforce the Trust’s right to apply excess cash flow to principal
in accordance with the terms of the Mortgage Loan documents. The Master Servicer or the Special Servicer, as applicable, may in
its discretion waive any Penalty Charge in connection with any delinquent payment on a Mortgage Loan or Serviced Companion Loan
three (3) times during any period of twenty-four (24) consecutive months with respect to any Mortgage Loan or Serviced Companion
Loan; provided that the Master Servicer or the Special Servicer, as applicable, may in its discretion waive any Penalty
Charge in connection with any delinquent payment on a Mortgage Loan or Serviced Companion Loan one additional time in such 24-month
period so long as with respect to any of the foregoing waivers, no Advance or additional expense of the Trust has been incurred
and remains unreimbursed to the Trust with respect to such Mortgage Loan or Serviced Companion Loan. Any additional waivers during
such 24-month period with respect to such Mortgage Loan may be made, subject to the Servicing Standard, only after the Master
Servicer or the Special Servicer, as the case may be, has, prior to the occurrence and continuance of a Consultation Termination
Event, given notice of a proposed waiver to the Directing Certificateholder and, prior to the occurrence and continuance of a
Control Termination Event, the Directing Certificateholder has consented to such additional waiver (provided that if the
Master Servicer or the Special Servicer, as applicable, fails to receive a response to such notice from the Directing Certificateholder
in writing within five (5) days of giving such notice, then the Directing Certificateholder shall be deemed to have consented
to such proposed waiver); provided, further, that after the occurrence and during the continuance of a Control Termination
Event, the Master Servicer or the Special Servicer, as the case may be, may waive any Penalty Charge in accordance with the Servicing
Standard without the consent of the Directing Certificateholder; provided, further, that the Directing Certificateholder
shall not have any consent or consultation rights with respect to any Mortgage Loan that is an Excluded Loan as to such party
with respect to the foregoing waivers.

 

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

 

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

 

     -161-

     

    

 

second,
as a recovery of Nonrecoverable Advances and any interest on those Nonrecoverable Advances at the Reimbursement Rate, to the extent
previously paid or reimbursed from principal collections on such Mortgage Loan (as described in the first proviso in the definition
of Aggregate Principal Distribution Amount);

 

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

 

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

 

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

 

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

 

seventh,

eighth,
as a recovery of any Yield Maintenance Charge or Prepayment Premium then due and owing under such Mortgage Loan;

 

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

 

     -162-

     

    

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

second,
as a recovery of Nonrecoverable Advances and any interest on those Nonrecoverable Advances at the Reimbursement Rate, to the extent
previously paid or

 

     -163-

     

    

 

reimbursed
from principal collections on the Mortgage Loans (as described in the first proviso in the definition of Aggregate Principal Distribution
Amount);

 

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

 

fourth,
to the extent not previously allocated pursuant to clause first, as a recovery of principal of such Mortgage Loan

related Net Mortgage Rate on the portion of the Stated Principal Balance of such Mortgage Loan equal to any related Collateral

have not been allocated as recovery of accrued and unpaid interest pursuant to this clause fifth or clause fifth
of the prior paragraph on earlier dates);

 

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

 

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

 

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

 

ninth,
as a recovery of any other amounts then due and owing under such Mortgage Loan other than remaining unpaid principal (if both consent

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

 

     -164-

     

    

 

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

 

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

 

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

 

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

 

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

 

     -165-

     

    

 

Loan
documents allow such action), unless holding or application of such funds would otherwise be inconsistent with the Mortgage Loan
documents or the Servicing Standard.

 

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

 

Section 3.03     Collection
of Taxes, Assessments and Similar Items; Servicing Accounts. (a) The Master Servicer shall establish and maintain one or more
accounts (the “Servicing Accounts”), into which all Escrow Payments received by it shall be deposited and retained,
and shall administer such Servicing Accounts in accordance with the related Mortgage Loan documents and, if applicable, the Companion
Loan documents. Any Servicing Account related to a Serviced Whole Loan shall be held for the benefit of the Certificateholders
and the related Serviced Companion Noteholder(s) collectively, but this shall not be construed to modify the respective interests
of any noteholder therein as set forth in the related Intercreditor Agreement. Amounts on deposit in Servicing Accounts may only
be invested in accordance with the terms of the related Mortgage Loan documents and Companion Loan documents, or in Permitted
Investments in accordance with the provisions of Section 3.06. Servicing Accounts shall be Eligible Accounts to the extent
permitted by the terms of the related Mortgage Loan documents. Withdrawals of amounts so deposited from a Servicing Account may
be made only to: (i) effect payment of items for which Escrow Payments were collected and comparable items; (ii) reimburse the
Trustee and then the Master Servicer, if applicable, for any Servicing Advances; (iii) refund to Mortgagors any sums as may be
determined to be overages; (iv) pay interest to Mortgagors on balances in the Servicing Account, if required by applicable law
or the terms of the related Mortgage Loan or Companion Loan and as described below or, if not so required, to the Master Servicer;
(v) after the occurrence of an event of default under the related Mortgage Loan or Companion Loan, apply amounts to the indebtedness
under the applicable Mortgage Loan or Companion Loan; (vi) withdraw amounts deposited in error; (vii) pay Penalty Charges to the
extent permitted by the related Mortgage Loan documents; or (viii) clear and terminate the Servicing Account at the termination
of this Agreement in accordance with Section 9.01. As part of its servicing duties, the Master Servicer shall pay or cause
to be paid to the related Mortgagors interest on funds in Servicing Accounts, to the extent required by law or the terms of the
related Mortgage Loan or Companion Loan; provided, however, that in no event shall the Master Servicer be required
to remit to any Mortgagor any amounts in excess of actual net investment income or funds in the related Servicing Account. If
allowed by the related Mortgage Loan documents and applicable law, the Master Servicer may charge the related Mortgagor an administrative
fee for maintenance of the Servicing Accounts.

 

     -166-

     

    

 

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

 

(c)       In
accordance with the Servicing Standard and for each Mortgage Loan (other than any Non-Serviced Mortgage Loans) and each Serviced
Whole Loan, as applicable, the Master Servicer shall advance all such funds as are necessary for the purpose of effecting the payment
of (i) real estate taxes, assessments and other similar items that are or may become a lien thereon, (ii) ground rents (if applicable)
and (iii) premiums on Insurance Policies, in each instance if and to the extent Escrow Payments collected from the related Mortgagor
(or related REO Revenues, if applicable) are insufficient to pay such item when due and the related Mortgagor has failed to pay
such item on a timely basis, and provided, however, that the particular advance would not, if made, constitute a
Nonrecoverable Servicing Advance and provided, further, however, that with respect to the payment of taxes
and assessments, the Master Servicer shall not be required to make such advance until the later of (i) five (5) Business Days after
the Master Servicer, the Special Servicer, the Certificate Administrator or the Trustee, as the case may be, has received confirmation
that such item has not been paid and (ii) the date prior to the date after which any penalty or interest would accrue in respect
of such taxes or assessments. The Special Servicer shall give the Master Servicer and the Trustee no less than

 

     -167-

     

    

 

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 in its sole discretion. Within five (5) Business Days of making such a Servicing
Advance, the Special Servicer shall deliver to the Master Servicer request for reimbursement for such Servicing Advance, along
with all information and documentation in the Special Servicer’s possession regarding the subject Servicing Advance as the
Master Servicer may reasonably request, and the Master Servicer shall be obligated, out of the Master Servicer’s own funds,
to reimburse the Special Servicer for any unreimbursed Servicing Advances (other than Nonrecoverable Servicing Advances) made
by the Special Servicer pursuant to the terms hereof, together with interest thereon at the Reimbursement Rate from the date made
to, but not including, the date of reimbursement. Such reimbursement and any accompanying payment of interest shall be made within
five (5) Business Days of the written request therefor pursuant to the preceding sentence by wire transfer of immediately available
funds to an account designated in writing by the Special Servicer. Upon the Master Servicer’s reimbursement to the Special
Servicer of any Servicing Advance and payment to the Special Servicer of interest thereon, all in accordance with this Section
3.03, the Master Servicer shall for all purposes of this Agreement be deemed to have made such Servicing Advance at the same
time as the Special Servicer actually made such Servicing Advance, and accordingly, the Master Servicer shall be entitled to be
reimbursed for such Servicing Advance, together with interest thereon at the Reimbursement Rate, at the same time, in the same
manner and to the same extent as the Master Servicer would otherwise have been entitled if it had actually made such Servicing
Advance at the time the Special Servicer did. Notwithstanding the foregoing provisions of this Section 3.03(c), the Master
Servicer shall not be required to reimburse the Special Servicer out of its own funds for, or to make at the direction of the
Special Servicer, any Servicing Advance if the Master Servicer determines in its reasonable judgment that such Servicing Advance,
although not characterized by the Special Servicer as a Nonrecoverable Servicing Advance, is in fact a Nonrecoverable Servicing
Advance. The Master Servicer shall notify the Special Servicer in writing of such determination and, if applicable, such Nonrecoverable
Servicing Advance shall instead be reimbursed to the Special Servicer pursuant to Section 3.05 of this Agreement.

 

Any request by the Special
Servicer that the Master Servicer make a Servicing Advance shall be deemed to be a determination by the Special Servicer that such
requested Servicing Advance is not a Nonrecoverable Servicing Advance, and the Master Servicer shall be entitled to conclusively
rely on such determination; provided that the determination shall not be binding on the Master Servicer or Trustee. On the
first Business Day after the Determination Date for the related Distribution Date, the Special Servicer shall report to the Master
Servicer if the Special Servicer determines any Servicing Advance previously made by the Master Servicer

 

     -168-

     

    

 

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

 

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

 

     -169-

     

    

 

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

 

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

received or made by or on behalf of it subsequent to the Cut-off Date (other than in respect of principal and interest on the
Mortgage Loans or Companion Loans due and payable on or before the Cut-off Date, which payments shall be delivered promptly to
the appropriate Mortgage Loan Seller or its respective designee and other than any amounts received from Mortgagors which are
received in connection with the purchase of defeasance collateral), or payments (other than Principal Prepayments) received by
it on or prior to the Cut-off Date but allocable to a period subsequent thereto:

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

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

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

 

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

 

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

 

(b)       The
Certificate Administrator, on behalf of the Trustee, shall establish and maintain (i) the Lower-Tier REMIC Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account and the Retained Certificate Gain-on-Sale Reserve Account in trust
for the benefit of the Certificateholders (other than Holders of the Excess Interest Certificates), (ii) the Upper-Tier REMIC Distribution
Account in trust for the benefit of the Certificateholders (other than the Holders of the Excess Interest Certificates) and (iii)
the Excess Interest Distribution Account in trust for the benefit of the Holders of the Excess Interest Certificates and the RR
Interest. 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 Aggregate Available Funds attributable to the
Mortgage Loans (in each case, calculated without regard to clauses (a)(iii)(B),

Interest Distribution Account all Excess Interest for the related Distribution Date then on deposit in the Collection Account
maintained by the Master Servicer after giving effect to withdrawals of funds pursuant 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 Account, the Interest Reserve Account and the Excess Interest Distribution Account shall remain uninvested.

 

The Certificate Administrator
shall, on any Distribution Date, make withdrawals from the Excess Interest Distribution Account to the extent required to make

the Companion Distribution Account shall be held for the benefit of the related Companion Holder. The Companion Paying Agent shall

an aggregate amount equal to all payments and/or collections actually received on, and payable in respect of, the applicable Serviced
Companion Loan prior to such date and deposit such amount in the Companion Distribution Account; provided, however,
that in no event shall the Master Servicer be required to transfer to the Companion Distribution Account any portion thereof that

the related Intercreditor Agreement; and (2) then, the Companion Paying Agent shall make the payments and remittance described
in Section 4.01(k). With respect to any Serviced Whole Loan, in the event the Master Servicer has received written notice
that an Other Servicer or Other Trustee has made an advance of a monthly debt service payment on a related Serviced Pari Passu
Companion Loan and the Master Servicer subsequently receives Late Collections in respect of such advanced payment, the Master Servicer
shall remit to the applicable Other Servicer or Other Trustee, within two (2) Business Days following receipt of such Late Collections
in properly identified funds, the amount allocable to such Serviced Pari Passu Companion Loan in accordance with the terms of this

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

The Certificate Administrator
shall, upon receipt, deposit in the Lower-Tier REMIC Distribution Account or the Excess Interest Distribution Account, as applicable,

therein.

 

Promptly on each Distribution

Gain-on-Sale Reserve Account, the Retained Certificate Gain-on-Sale Reserve Account, the Interest Reserve Account, the Excess Interest
Distribution Account, the Upper-Tier REMIC Distribution Account or the Lower-Tier REMIC Distribution Account shall not be invested
for so long as Wells Fargo Bank, National Association is the Certificate Administrator; provided, however, that such
funds may be invested and, if invested, shall be invested by, and at the risk of, the Certificate Administrator (but only if the
Certificate Administrator is not Wells Fargo Bank, National Association) in Permitted Investments selected by the party hereunder
that maintains such account which shall mature, unless payable on demand, not later than such time on the Distribution Date which
will allow the Certificate Administrator to make withdrawals from the Distribution Account, and any such Permitted Investment shall
not be sold or disposed of prior to its maturity unless payable on demand. All such Permitted Investments to be administered by

on such Permitted Investments.

 

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

 

As of the Closing Date,
the Interest Reserve Account, the Excess Interest Distribution Account, the Upper-Tier REMIC Distribution Account and the Lower-Tier
REMIC Distribution Account shall be located at the offices of the Certificate Administrator. The Certificate Administrator shall
give notice to the Trustee, the Master Servicer, and the Depositor of the proposed location of the Interest Reserve Account, the
Excess Interest Distribution Account, the Upper-Tier REMIC Distribution Account, the Lower-Tier REMIC Distribution Account, and,

(c)       Prior
to any Determination Date for the first Collection Period during which Excess Interest is received on any Mortgage Loan, and upon

behalf of the Certificateholders, shall establish and maintain the Excess Interest Distribution Account in its own name on behalf
of the Trustee in trust for the benefit of the Holders of the Excess Interest Certificates and the RR Interest. The Excess Interest

Certificate Administrator shall establish (upon notice from the Special Servicer of an event occurring that generates Gain-on-Sale
Proceeds) and maintain (i) the Gain-on-Sale Reserve Account for the benefit of the Certificateholders (other than Holders of the

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 account for the Loss of Value Reserve Fund as an outside reserve fund within

for all federal tax purposes, the Certificate Administrator shall (i) treat amounts paid out of the Loss of Value Reserve Fund
through the Collection Account to the Certificateholders as paid to and distributed by the Trust REMICs and (ii) treat any amounts
paid out of the Loss of Value Reserve Fund through the Collection Account to a Mortgage Loan Seller as distributions by the Trust
to such Mortgage Loan Seller as beneficial owner of the Loss of Value Reserve Fund. The applicable Mortgage Loan Seller will be
the beneficial owner of the Loss of Value Reserve Fund for all federal income tax purposes, and shall be taxable on all income
earned thereon.

sufficient
to reimburse the full amount of Advances and interest thereon listed in Sections 3.05(a)(ii), (a)(iii), (a)(iv),

pay, in accordance with Section 3.05(a) of this Agreement, or to reimburse the Trust for the prior payment of, any expense

of any other Mortgage Loan or Serviced REO Loan; and

 

(v)       On
the final Distribution Date after all distributions have been made as set forth in clauses (i)-(iv) above, to each Mortgage
Loan Seller, its pro rata share, based on the amount that it contributed, net of any amount contributed by such Mortgage

respect thereto for which such Loss of Value Payments were received; and any Loss of Value Payments transferred to the Collection
Account pursuant to clause (iv) of the prior paragraph shall be treated as Liquidation Proceeds received by the Trust in
respect of the related Mortgage Loan or REO Loan for which such Loss of Value Payments are being transferred to the Collection

Section
3.06     Investment of Funds in the Collection Account and the REO Account. (a) The Master
Servicer may direct any depository institution maintaining the Collection Account, the Companion Distribution Account, or any
Servicing Account (for purposes of this Section 3.06, an “Investment Account”), the Special
Servicer may direct any depository institution maintaining the REO Account or Loss of Value Reserve Fund (also for purposes
of this Section 3.06, an “Investment Account”) to invest or if it is such depository institution,
may itself invest, the funds held therein, only in one or more Permitted Investments bearing interest or sold at a discount,
and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the next succeeding date on
which funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the depository
institution maintaining such account is the obligor thereon and (ii) no later than the date on which funds are required to be
withdrawn from such account pursuant to this Agreement, if the depository institution maintaining such account is the obligor
thereon. All such Permitted Investments shall be held to maturity, unless payable on demand. Any funds held in an Investment
Account shall be held in the name of the Master Servicer or the Special Servicer, as the case may be, on behalf of the
Trustee (in its capacity as such) for the benefit of the Certificateholders. The Master Servicer (in the case of the
Collection Account, the Companion Distribution Account or any Servicing Account maintained by or for the Master
Servicer), the Special Servicer (in the case of the REO Account, the Loss of Value Reserve Fund or any Servicing Account
maintained by or for the Special Servicer) on behalf of the Trustee, shall maintain continuous physical possession of any
Permitted Investment of amounts in the Collection Account, the Companion Distribution Account, the Servicing Accounts, the
Loss of Value Reserve Fund or the REO Account, as applicable, that is either (i) a “certificated security,” as
such term is defined in the UCC (such that the Trustee shall have control pursuant to Section 8-106 of the UCC) or (ii) other
property in which a secured party may perfect its security interest by physical possession under the UCC or any other
applicable law. In the case of any Permitted Investment held in the form of a “security entitlement” (within the
meaning of Section 8-102(a)(17) of the UCC), the Master Servicer or the Special Servicer, as the case may be, shall take or
cause to be taken such action as the Trustee deems reasonably necessary to cause the Trustee to have control over such
security entitlement. In the event amounts on deposit 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:

 

     -188-

     

    

 

 

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

 

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

 

(b)       Interest
and investment income realized on funds deposited in the Collection Account, the Companion Distribution Account or any Servicing
Account maintained by or for the Master Servicer to the extent of the Net Investment Earnings, if any, with respect to such account
for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the current
Distribution Date, shall be for the sole and exclusive benefit of the Master Servicer to the extent (with respect to Servicing
Accounts) not required to be paid to the related Mortgagor and shall be subject to its withdrawal, or withdrawal at its direction,
in accordance with Section 3.03 or Section 3.05(a), as the case may be. Interest and investment income realized on
funds deposited in the REO Account, the Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer,
to the extent of the Net Investment Earnings, if any, with respect to such account for each period from and including any Distribution
Date to and including the immediately succeeding P&I Advance Date, shall be for the sole and exclusive benefit of the Special
Servicer and shall be subject to its withdrawal in accordance with Section 3.14(c). In the event that any loss shall be
incurred in respect of any Permitted Investment (as to which the Master Servicer or Special Servicer, as the case may be, would
have been entitled to any Net Investment Earnings hereunder) directed to be made by the Master Servicer or the Special Servicer,
as the case may be, and on deposit in any of the Collection Account, the Companion Distribution Account, the Servicing Account,
Loss of Value Reserve Fund or the REO Account, the Master Servicer (in the case of the Collection Account, the Companion Distribution
Account or any Servicing Account maintained by or for the Master Servicer), the Special Servicer (in the case of the REO Account,
the Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) shall deposit therein, no later
than the P&I Advance Date, without right of reimbursement, the amount of Net Investment Loss, if any, with respect to such
account for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the
current Distribution Date; provided that neither the Master Servicer nor the Special Servicer shall be required to deposit
any loss on an investment of funds in an Investment Account if such loss is incurred solely as a result of the insolvency of the
federal or state chartered depository institution or trust company that holds such Investment Account, so long as such depository
institution or trust company satisfied the qualifications set forth in the definition of Eligible Account at the time such investment
was made (and, with respect to the Master Servicer, such federal or state chartered depository institution or trust company is
not an Affiliate of the Master Servicer unless such depository institution or trust company satisfied the qualification set forth
in the definition of Eligible Account both (x) at the time the investment was made and (y) thirty (30) days prior to such insolvency).

 

     -189-

     

    

 

(c)       Except
as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment,
or if a default occurs in any other performance required under any Permitted Investment, the Master Servicer may and, upon the
request of Holders of Certificates entitled to more than 50% of the Voting Rights allocated to any Class shall, take such action
as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings.

 

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

 

     -190-

     

    

 

maintain
(or to itself maintain) insurance against property damage resulting from terrorist or similar acts unless the Mortgagor’s
failure is an Acceptable Insurance Default (as determined by the Master Servicer (with respect to a Non-Specially Serviced Loan)
or the Special Servicer (with respect to a Specially Serviced Loan) with the consent of the Directing Certificateholder (unless
a Control Termination Event has occurred) and after consultation by the Special Servicer with the Risk Retention Consultation
Party pursuant to Section 6.08(a) (in each case, other than with respect to any Excluded Loan as to such party)) and only
in the event the Trustee has an insurable interest therein and such insurance is available to the Master Servicer or the Special
Servicer, as the case may be, and, if available, can be obtained at commercially reasonable rates. The Master Servicer and the
Special Servicer shall be entitled to rely on insurance consultants (at the applicable servicer’s expense) in determining
whether any insurance is available at commercially reasonable rates. Subject to Section 3.15(a) and the costs of such insurance
being reimbursed or paid to the Special Servicer as provided in the third-to-last sentence of this paragraph, the Special Servicer
shall maintain for each REO Property (other than any Non-Serviced Mortgaged Property) no less insurance coverage than was previously
required of the Mortgagor under the related Mortgage Loan documents unless the Special Servicer determines with the consent of
the Directing Certificateholder (prior to the occurrence and continuance of a Control Termination Event) and after consultation
by the Special Servicer with the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case other than
with respect to a Mortgage Loan that is an Excluded Loan as to such party) that such insurance is not available at commercially
reasonable rates or that the Trustee does not have an insurable interest, in which case the Master Servicer shall be entitled
to conclusively rely on the Special Servicer’s determination. All Insurance Policies maintained by the Master Servicer or
the Special Servicer shall (i) contain a “standard” mortgagee clause, with loss payable to the Master Servicer on
behalf of the Trustee (in the case of insurance maintained in respect of Mortgage Loans (other than any Non-Serviced Mortgage
Loan), including any related Serviced Companion Loan, other than REO Properties) or to the Special Servicer on behalf of the Trustee
(in the case of insurance maintained in respect of REO Properties), (ii) be in the name of the Trustee (in the case of insurance
maintained in respect of REO Properties), (iii) include coverage in an amount not less than the lesser of (x) the full replacement
cost of the improvements securing Mortgaged Property or the REO Property, as applicable, and (y) the outstanding principal balance
owing on the related Mortgage Loan (including any related Serviced Companion Loan) or REO Loan, as applicable, and in any event,
the amount necessary to avoid the operation of any co-insurance provisions, (iv) include a replacement cost endorsement providing
no deduction for depreciation (unless such endorsement is not permitted under the related Mortgage Loan documents), (v) be noncancelable
without thirty (30) days prior written notice to the insured party (except in the case of nonpayment, in which case such policy
shall not be cancelled without ten (10) days prior notice) and (vi) subject to the first proviso in the second sentence of this
Section 3.07(a), be issued by a Qualified Insurer authorized under applicable law to issue such Insurance Policies. Any
amounts collected by the Master Servicer or the Special Servicer under any such Insurance Policies (other than amounts to be applied
to the restoration or repair of the related Mortgaged Property or REO Property or 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

 

     -191-

     

    

 

than REO Properties and other than any Non-Serviced Mortgage Loan) (i) if the Mortgagor defaults on its obligation to do so, shall
be advanced by the Master Servicer as a Servicing Advance (so long as such Advance would not be a Nonrecoverable Advance and if
such Advance would be a Nonrecoverable Advance then such cost shall instead be paid out of the Collection Account) and will be
charged to the related Mortgagor and (ii) shall not, for purposes of calculating monthly distributions to Certificateholders,
be added to the unpaid principal balance of the related Mortgage Loan and Serviced Companion Loan (if any), notwithstanding that
the terms of such Mortgage Loan or Serviced Companion Loan so permit. Any cost incurred by the Special Servicer in maintaining
any such Insurance Policies with respect to REO Properties shall be an expense of the Trust payable out of the related REO Account
pursuant to Section 3.14(c) or, if the amount on deposit therein is insufficient therefor, advanced by the Master Servicer
as a Servicing Advance (so long as such Advance would not be a Nonrecoverable Advance and if such Advance would be a Nonrecoverable
Advance then such cost shall instead be paid out of the Collection Account). The foregoing provisions of this Section 3.07 shall apply to any Serviced Whole Loan as if it were a single “Mortgage Loan”. Notwithstanding any provision to
the contrary, the Master Servicer will not be required to maintain, and will not be in default for failing to obtain, any earthquake
or environmental insurance on any Mortgaged Property unless such insurance was required at the time of origination of the related
Mortgage Loan (other than a Non-Serviced Mortgage Loan) and is currently available at commercially reasonable rates.

 

Notwithstanding the foregoing,
with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that either
(x) require the Mortgagor to maintain “all risk” property insurance (and do not expressly permit an exclusion for terrorism)
or (y) contain provisions generally requiring the applicable Mortgagor to maintain insurance in types and against such risks as
the holder of such Mortgage Loan (including any related Serviced Companion Loan) reasonably requires from time to time in order
to protect its interests, the Master Servicer shall, consistent with the Servicing Standard, (A) monitor in accordance with the
Servicing Standard whether the insurance policies for the related Mortgaged Property contain Additional Exclusions; provided
that the Master Servicer shall be entitled to conclusively rely upon certificates of insurance in determining whether such policies
contain Additional Exclusions, (B) request the Mortgagor to either purchase insurance against the risks specified in the Additional
Exclusions or provide an explanation as to its reasons for failing to purchase such insurance and (C) if the related Mortgage Loan
is a Specially Serviced Loan, notify the Special Servicer if it has knowledge that any insurance policy contains Additional Exclusions
or if it has knowledge (such knowledge to be based upon the Master Servicer’s compliance with the immediately preceding clauses
(A) and (B) above) that any Mortgagor under a Specially Serviced Loan fails to purchase the insurance requested to be
purchased by the Master Servicer pursuant to clause (B) above. If the Master Servicer (with respect to a Non-Specially Serviced
Loan) or the Special Servicer (with respect to a Specially Serviced Loan) determines in accordance with the Servicing Standard
that such failure is not an Acceptable Insurance Default, the Special Servicer (with regard to such determination made by the Special
Servicer) shall notify the Master Servicer and the Master Servicer shall use efforts consistent with the Servicing Standard to
cause such insurance to be maintained. The Master Servicer and the Special Servicer (at the expense of the Trust) shall be entitled
to rely on insurance consultants in making such determinations. The Master Servicer shall be entitled to rely on insurance consultants
(at the expense of the Master Servicer) in determining whether

 

     -192-

     

    

 

Additional
Exclusions exist. Furthermore, the Master Servicer or the Special Servicer, as applicable, shall promptly deliver such conclusions
in writing to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website for those Mortgage
Loans that (i) have one of the ten (10) highest outstanding Stated Principal Balances of all of the Mortgage Loans then included
in the Trust or (ii) comprise more than 5% of the outstanding Stated Principal Balance of the Mortgage Loans then included in
the Trust. During the period that the Master Servicer or the Special Servicer is evaluating the availability of such insurance
or waiting for a response from the Directing Certificateholder or (solely with respect to Specially Serviced Loans) upon the request
of the Risk Retention Consultation Party, consulting (on a non-binding basis) with the Risk Retention Consultation Party pursuant
to Section 6.08(a), neither the Master Servicer nor the Special Servicer will be liable for any loss related to its failure
to require the Mortgagor to maintain (or its failure to maintain) such insurance and will not be in default of its obligations
as a result of such failure and the Master Servicer will not itself maintain such insurance or cause such insurance to be maintained.

 

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

 

(ii)       If
the Master Servicer or the Special Servicer shall cause any Mortgaged Property or REO Property to be covered by a master single
interest or force-placed insurance policy with a Qualified Insurer naming the Master Servicer or the Special Servicer on behalf
of the Trustee as the loss payee, then to the extent such Insurance Policy provides protection equivalent to the individual policies
otherwise required, the

 

     -193-

     

    

 

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

 

(c)       The
Master Servicer and the Special Servicer shall each obtain and maintain at its own expense and keep in full force and effect throughout
the term of this Agreement a blanket fidelity bond and an errors and omissions insurance policy with a Qualified Insurer covering
losses that may be sustained as a result of an officer’s or employee’s misappropriation of funds or errors or omissions.
Such amount of coverage shall be in such form and amount as are consistent with the Servicing Standard. Coverage of the Master
Servicer or the Special Servicer under a policy or bond obtained by an Affiliate of the Master Servicer or the Special Servicer
and providing the coverage required by this Section 3.07(c) shall satisfy the requirements of this Section 3.07(c).
The Special Servicer and the Master Servicer will promptly report in writing to the Trustee any material changes that may occur
in their respective fidelity bonds, if any, and/or their respective errors and omissions insurance policies, as the case may be,
and will furnish to the Trustee copies of all binders and policies or certificates evidencing that such bonds, if any, and insurance
policies are in full force and effect.

 

(d)       At
the time the Master Servicer determines in accordance with the Servicing Standard that any Mortgaged Property (other than a Non-Serviced
Mortgaged Property) is in a federally designated special flood hazard area (and such flood insurance has been made available),
the Master Servicer will use efforts consistent with the Servicing Standard to cause the related Mortgagor (in accordance with
applicable law and the terms of the Mortgage Loan and related Serviced Companion Loan documents) to maintain, and, if the related
Mortgagor shall default in its obligation to so maintain, shall itself maintain to the extent such insurance is available at commercially
reasonable rates (as determined by the Master Servicer in accordance with the Servicing Standard and to the extent the Trustee,
as mortgagee, has an insurable interest therein), flood insurance in respect thereof, but only to the extent the related Mortgage
Loan (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan permits the mortgagee to require such coverage
and the maintenance of such coverage is consistent with the Servicing Standard. Such flood insurance shall be in an amount equal
to the

 

     -194-

     

    

 

lesser
of (i) the unpaid principal balance of the related Mortgage Loan (and any related Serviced Companion Loan, if applicable), and
(ii) the maximum amount of insurance which is available under the National Flood Insurance Act of 1968, as amended, plus such
additional excess flood coverage with respect to the Mortgaged Property, if any, in an amount consistent with the Servicing Standard.
If the cost of any insurance described above is not borne by the Mortgagor, the Master Servicer shall promptly make a Servicing
Advance for such costs.

 

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

 

(f)       Notwithstanding
the foregoing, so long as the long-term debt obligations or the deposit account or claims-paying ability of the Master Servicer
(or its immediate or remote parent) or the Special Servicer (or its immediate or remote parent), as applicable, is rated at least
“A3” by Moody’s or “A-” by Fitch, the Master Servicer (or its public parent) or the Special Servicer
(or its public parent), as applicable, shall be allowed to provide self-insurance with respect to any of its obligations under
this Section 3.07.

 

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

 

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

 

(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;

 

     -195-

     

    

 

then, for so long as
such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement, the Master Servicer (with respect
to any Non-Specially Serviced Loan as to which such matter is a Master Servicer Decision pursuant to clause (xiii) of the
definition thereof) or the Special Servicer (with respect to any Specially Serviced Loan or any Non-Specially Serviced Loan as
to which such matter is a Major Decision or Special Servicer Decision), on behalf of the Trustee as the mortgagee of record, shall
(a) exercise any right it may have with respect to such Mortgage Loan or related Companion Loan (x) to accelerate the payments
thereon or (y) to withhold its consent to any sale or transfer, consistent with the Servicing Standard or (b) waive any right to
exercise such rights, provided that (i) other than with respect to a Master Servicer Decision pursuant to clause (xiii)
of the definition thereof, (A) if such Mortgage Loan is not an Excluded Loan with respect to the Directing Certificateholder, no
Control Termination Event shall have occurred and be continuing and the matter involves a Major Decision, the consent (or deemed
consent) of the Directing Certificateholder shall have been obtained by the Special Servicer to the extent required by, and pursuant
to the process described under, Section 6.08(a), (B) if such Mortgage Loan is not an Excluded Loan with respect to the Directing
Certificateholder, a Control Termination Event shall have occurred and be continuing and no Consultation Termination Event shall
have occurred and be continuing, the Special Servicer shall have consulted with the Directing Certificateholder if and to the extent
required pursuant to Section 6.08(a) and (C) if such Mortgage Loan is not an Excluded Loan with respect to the Risk Retention
Consultation Party and (x) such Mortgage Loan is a Specially Serviced Loan or (y) a Consultation Termination Event shall have occurred
and be continuing, the Special Servicer shall have consulted with the Risk Retention Consultation Party if and to the extent required
pursuant to Section 6.08(a) (provided that in the case of clause (A), clause (B) and clause (C)
such consent shall be deemed given or such consultation shall be deemed to have occurred, as applicable, if a response to the request
for consent or consultation, as the case may be, is not provided within ten (10) Business Days after receipt of the Special Servicer’s
written recommendation and analysis and all information reasonably requested by the Directing Certificateholder or the Risk Retention
Consultation Party, as applicable, and reasonably available to such Special Servicer in order to grant or withhold such consent
or conduct such consultation), and (ii) with respect to any Mortgage Loan (x) with a Stated Principal Balance greater than or equal
to $20,000,000, (y) with a Stated Principal Balance greater than or equal to 5% of the aggregated Stated Principal Balance of the
Mortgage Loans then outstanding or (z) together with all other Mortgage Loans with which it is cross-collateralized or cross-defaulted
or together with all other Mortgage Loans with the same Mortgagor (or an Affiliate thereof), that is one of the ten (10) largest
Mortgage Loans outstanding (by Stated Principal Balance), the Master Servicer or the Special Servicer, as the case may be, prior
to consenting to any action, shall obtain, a Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable
rating agency that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any
class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section
3.25), provided, however, that with respect to sub-clauses (y) and (z) of this sub-clause (ii),
such Mortgage Loan shall also have a Stated Principal Balance of at least $10,000,000 for such Rating Agency Confirmation requirement
to apply. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class

 

     -196-

     

    

 

(regardless
of whether a Control Termination Event has occurred and is continuing), the Special Servicer shall consult with the Operating
Advisor, on a non-binding basis, in connection with the related transactions involving proposed Major Decisions and consider alternative
actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting with the Operating Advisor.

 

With respect to any “due-on-sale”
matter described above that is a Major Decision related to any Mortgage Loan that is not an Excluded Loan with respect to the Risk
Retention Consultation Party or the holder of the majority of the RR Interest, upon request of the Risk Retention Consultation
Party, the Special Servicer shall consult on a non-binding basis with the Risk Retention Consultation Party with respect to (i)
prior to the occurrence and continuance of a Consultation Termination Event, Specially Serviced Loans; and (ii) following the occurrence
and during the continuance of a Consultation Termination Event, all Mortgage Loans, within the same time period as it would obtain
the consent of, or consult with, the Directing Certificateholder with respect to the above 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 Master Servicer or the Special Servicer, as the case may
be, shall (if not already provided in accordance with Section 3.25 of this Agreement) deliver a Review Package to the 17g-5
Information Provider (or, with respect to any Serviced Companion Loan Securities, the related 17g-5 information provider) in accordance
with Section 3.25 of this Agreement.

 

If any Mortgage Loan
(other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan provides that such Mortgage Loan or related Serviced
Companion Loan may be assumed or transferred without the consent of the mortgagee provided that certain conditions contained
in the related Mortgage Loan documents are satisfied where no mortgagee discretion is necessary in order to determine if such conditions
are satisfied, then for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement,
the Master Servicer (with respect to all Non-Specially Serviced Loans) and the Special Servicer (with respect to all Specially
Serviced Loans), on behalf of the Trustee as the mortgagee of record, shall determine in accordance with the Servicing Standard
whether such conditions have been satisfied.

 

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

 

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

 

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

 

     -197-

     

    

 

then, for so long as
such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement, the Master Servicer (with respect
to any Non-Specially Serviced Loan and as to which such matter is a Master Servicer Decision pursuant to clause (xiii) or
clause (xv) of the definition thereof) or the Special Servicer (with respect to any Specially Serviced Loan or any Non-Specially
Serviced Loan as to which such matter is a Major Decision or Special Servicer Decision), on behalf of the Trustee as the mortgagee
of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or related Companion Loan (x) to accelerate
the payments thereon or (y) to withhold its consent to the creation of any additional lien or other encumbrance, consistent with
the Servicing Standard or (b) waive its right to exercise such rights, provided that (i) other than with respect to a Master
Servicer Decision pursuant to clause (xiii) or clause (xv) of the definition thereof, (A) if such Mortgage Loan is
not an Excluded Loan with respect to the Directing Certificateholder, no Control Termination Event shall have occurred and be continuing
and the matter involves a Major Decision, the consent (or deemed consent) of the Directing Certificateholder shall have been obtained
by the Special Servicer to the extent required by, and pursuant to the process described under, Section 6.08(a), (B) if
such Mortgage Loan is not an Excluded Loan with respect to the Directing Certificateholder, a Control Termination Event shall have
occurred and be continuing, and no Consultation Termination Event shall have occurred and be continuing, the Special Servicer shall
have consulted with the Directing Certificateholder if and to the extent required pursuant to Section 6.08(a) and (C) if
such Mortgage Loan is not an Excluded Loan with respect to the Risk Retention Consultation Party and (x) such Mortgage Loan is
a Specially Serviced Loan or (y) a Consultation Termination Event shall have occurred and be continuing, the Special Servicer shall
have consulted with the Risk Retention Consultation Party if and to the extent required pursuant to Section 6.08(a) (provided
that in the case of clause (A), clause (B) and clause (C) such consent shall be deemed given or such consultation
shall be deemed to have occurred, as applicable, if a response to the request for consent or consultation, as the case may be,
is not provided within ten (10) Business Days after receipt of the Special Servicer’s written recommendation and analysis
and all information reasonably requested by the Directing Certificateholder or the Risk Retention Consultation Party, as applicable,
and reasonably available to such Special Servicer in order to grant or withhold such consent or conduct such consultation), and
(ii) such Master Servicer or such Special Servicer, as the case may be, has obtained Rating Agency Confirmation from each Rating
Agency and a confirmation of any applicable rating agency that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency
confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with
respect to the Certificates pursuant to Section 3.25) if such Mortgage Loan (A) has an outstanding principal balance that is greater
than or equal to 2% of the Stated Principal Balance of the outstanding Mortgage Loans or (B) has an LTV Ratio greater than 85%
(including any existing and proposed debt) or (C) has a debt service coverage ratio less than 1.20x (in each case, determined based
upon the aggregate of the Stated Principal Balance of the Mortgage Loan and related Companion Loan, if any, and the principal amount
of the proposed additional lien) or (D) is one of the ten largest Mortgage Loans (by Stated Principal Balance) or (E) has a Stated
Principal Balance greater than $20,000,000; provided, however, that with respect to sub-clauses (A), (B),
(C) and (D) of this sub-clause (ii), such Mortgage Loan shall also have a Stated Principal Balance of at least
$10,000,000 for such Rating Agency Confirmation requirement to apply. Notwithstanding anything herein to the contrary, with respect
to any

 

     -198-

     

    

 

Excluded
Loan with respect to the Directing Certificateholder (regardless of whether a Control Termination Event has occurred and is continuing),
the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions
involving proposed Major Decisions and consider alternative actions recommended by the Operating Advisor, in respect thereof,
in accordance with the procedures set forth in Section 6.08 for consulting with the Operating Advisor.

 

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

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

 

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

 

If any Mortgage Loan
or related Companion Loan provides that such Mortgage Loan or related Companion Loan may be further encumbered without the consent
of the mortgagee provided that certain conditions contained in the related Mortgage Loan documents are satisfied where no
mortgagee discretion is necessary in order to determine if such conditions are satisfied, then for so long as such Mortgage Loan
or related Companion Loan is being serviced under this Agreement, the Master Servicer (with respect to all Non-Specially Serviced
Loans) and the Special Servicer (with respect to all Specially Serviced Loans), on behalf of the Trustee as the mortgagee of record,
shall determine whether such conditions have been satisfied.

 

Upon receiving a request
for any matter described in Section 3.08(a) or this Section 3.08(b) that constitutes a consent or waiver with respect
to a “due-on-sale” or “due-on-encumbrance” clause with respect to a Mortgage Loan that is a Non-Specially
Serviced Loan and other than any transfers provided for in clause (xiii) of the definition of Master Servicer Decision and
other than any waiver of a “due-on-encumbrance” clause which waiver constitutes a Master Servicer Decision pursuant
to clause (xiii) of the definition thereof, the

 

     -199-

     

    

 

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

 

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

 

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

 

(e)       [RESERVED].

 

(f)       For
the avoidance of doubt, neither the Master Servicer nor the Special Servicer may waive its rights or grant its consent under any
“due-on-sale” or “due-on-encumbrance” clause other than in compliance with the provisions of Section
3.08(a) through (d) hereof. In the case of the Special Servicer, no such waiver or consent shall be made without (x)
(i) prior to the occurrence and continuance of a Control Termination Event and (ii) other than with respect to any Excluded Loan,
with respect to the Directing Certificateholder, the consent (or deemed consent) of the Directing Certificateholder having been
obtained if and to the extent required by, and pursuant to the process described under Section 6.08(a) or (y) (i) after
the occurrence and during the continuance of a Control Termination Event and (ii) other than with respect to any Excluded Loan
with respect to the Directing Certificateholder, but prior to

 

     -200-

     

    

 

the
occurrence and continuance of a Consultation Termination Event, after having consulted with the Directing Certificateholder if
and to the extent required pursuant to Section 6.08(a).

 

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

 

Section
3.09     Realization Upon Defaulted Loans and Companion Loans. (a) Upon an event of default
under the Mortgage Loan documents related to a Serviced Whole Loan or a Mortgage Loan with mezzanine debt, the Master
Servicer shall promptly provide written notice to the related Companion Holder or mezzanine lender, as applicable, with a
copy of such notice to the Special Servicer. The Special Servicer shall, subject to subsections (b) through (d)
of this Section 3.09 and Section 3.24, subject to the Directing Certificateholder’s and the Risk
Retention Consultation Party’s respective rights pursuant to Section 6.08, and any Companion Holder or mezzanine
lender’s rights under the related Intercreditor Agreement (in the case of a Serviced Whole Loan, on behalf of the
holders of the beneficial interest of the related Companion Loan) or this Agreement, exercise reasonable efforts,
consistent with the Servicing Standard, to foreclose upon or otherwise comparably convert (which may include an REO
Acquisition) the ownership of property securing any such Mortgage Loan (other than any Non-Serviced Mortgage Loan) and
related Companion Loan, if any, as come into and continue in default as to which no satisfactory arrangements (including by
way of a discounted pay-off) can be made for collection of delinquent payments, and which are not released from the Trust
Fund pursuant to any other provision hereof. The foregoing is subject to the provision that, in any case in which a Mortgaged
Property shall have suffered damage from an Uninsured Cause, the Master Servicer or the Special Servicer shall not be
required to make a Servicing Advance and expend funds toward the restoration of such property unless the Special Servicer has
determined in its reasonable discretion that such restoration will increase the net proceeds of liquidation of such Mortgaged
Property to Certificateholders after reimbursement to the Master Servicer or the Special Servicer, as applicable, for such
Servicing Advance, and the Master Servicer or the Special Servicer has not determined that such Servicing Advance together
with accrued and unpaid interest thereon would constitute a Nonrecoverable Advance. The costs and expenses incurred by the
Special Servicer in any such proceedings shall be advanced by the Master Servicer; provided that, in each case, such
cost or expense would not, if incurred, constitute a Nonrecoverable Servicing Advance. Nothing contained in this Section
3.09 shall be construed so as to require the Master Servicer or the Special Servicer, on behalf of the Trust, to make an
offer on any Mortgaged Property at a foreclosure sale or similar proceeding that is in excess of the fair market value of
such property, as determined by the Master Servicer or the Special Servicer in its reasonable judgment taking into
account the factors described in Section 3.16(b) and the results of any Appraisal obtained pursuant to the following
sentence, all such offers to be made in a manner consistent with the Servicing Standard. If and when the Special Servicer or
the Master Servicer deems it necessary and prudent for purposes of establishing the fair market

 

     -201-

     

    

 

value
of any Mortgaged Property securing a Defaulted Loan or any related defaulted Companion Loan, whether for purposes of making an
offer at foreclosure or otherwise, the Special Servicer or the Master Servicer, as the case may be, is authorized to have an Appraisal
performed with respect to such property by an Independent MAI-designated appraiser the cost of which shall be paid by the Master
Servicer as a Servicing Advance.

 

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

 

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

 

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

 

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

 

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

 

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

 

     -202-

     

    

 

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

 

(d)       If
(i) the environmental testing contemplated by subsection (c) above establishes that either of the conditions set forth in
clauses (i) and (ii) of subsection (c) above of the first sentence thereof has not been satisfied with respect
to any Mortgaged Property securing a Defaulted Loan and, in the case of a Serviced Mortgage Loan, any related Companion Loan, and
(ii) there has been no breach of any of the representations and warranties set forth in or required to be made pursuant to Section
4 of each of the Mortgage Loan Purchase Agreements for which the applicable Mortgage Loan Seller could be required to repurchase
such Defaulted Loan pursuant to Section 5 of the applicable Mortgage Loan Purchase Agreement, then the Special Servicer shall take
such action as it deems to be in the best economic interest of the Trust (other than proceeding to acquire title to the Mortgaged
Property) and is hereby authorized, with the consent of the Directing Certificateholder and after consultation with the Risk Retention
Consultation Party pursuant to Section 6.08(a) (in each case, (A) prior to the occurrence and continuance of a Control Termination
Event (or with respect to any AB Mortgage Loan, after the occurrence and during the continuation of an AB Control Appraisal Period,
but prior to the occurrence and continuance of a Control Termination Event) and (B) other than with respect to any Excluded Loan
as to such party) at such time as it deems appropriate to release such Mortgaged Property from the lien of the related Mortgage,
provided that, if such Mortgage Loan has a then-outstanding principal balance of greater than $1,000,000, then prior to
the release of the related Mortgaged Property from the lien of the related Mortgage, (i) the Special Servicer shall have notified
the Rating Agencies, the Trustee, the Certificate Administrator, the Master Servicer, the Directing Certificateholder and the Risk
Retention Consultation Party (in the case of the Directing Certificateholder, prior to the occurrence and continuance of a Consultation
Termination Event, and in the case of the Directing Certificateholder or the Risk Retention Consultation Party other than with
respect to any Excluded Loan as to such party), in writing of its intention to so release such Mortgaged Property and the bases
for such intention, (ii) the

 

     -203-

     

    

 

Certificate
Administrator shall have posted such notice of the Special Servicer’s intention to so release such Mortgaged Property to
the Certificate Administrator’s Website pursuant to Section 3.13(b) and (iii) in addition to the prior written consent
of the Directing Certificateholder as required above, the Holders of Certificates entitled to more than 50% of the Voting Rights
shall have consented or have been deemed to have consented to such release within thirty (30) days of the Certificate Administrator’s
posting such notice to the Certificate Administrator’s Website (failure to respond by the end of such 30-day period being
deemed consent of the Holders of the Certificates). To the extent any fee charged by any Rating Agency in connection with rendering
such written confirmation is not paid by the related Mortgagor, such fee is to be an expense of the Trust; provided that
the Special Servicer shall use commercially reasonable efforts to collect such fee from the Mortgagor to the extent permitted
under the related Mortgage Loan documents.

 

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

 

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

 

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

 

(h)       The
Special Servicer shall maintain accurate records, prepared by one of its Servicing Officers, of each Final Recovery Determination
in respect of a Defaulted Loan (other than with respect to a Non-Serviced Mortgage Loan) or defaulted Companion Loan or any REO
Property (other than any Non-Serviced Mortgaged Property) and the basis thereof. Each Final Recovery Determination shall be evidenced
by an Officer’s Certificate promptly delivered to the Trustee, the Certificate Administrator, the Directing Certificateholder
and the Risk

 

     -204-

     

    

 

Retention
Consultation Party (but in the case of the Directing Certificateholder and the Risk Retention Consultation Party, other than with
respect to any Excluded Loan as to such party) and the Master Servicer and in no event later than the next succeeding P&I
Advance Determination Date.

 

Section
3.10     Trustee and Certificate Administrator to Cooperate; Release of Mortgage Files. (a)
Upon the payment in full of any Mortgage Loan (other than a Non-Serviced Mortgage Loan), or the receipt by the Master
Servicer or the Special Servicer, as the case may be, of a notification that payment in full shall be escrowed in a manner
customary for such purposes, the Master Servicer or the Special Servicer, as the case may be, will promptly notify the
Trustee and the Custodian and request delivery of the related Mortgage File. Any such notice and request shall be in the form
of a Request for Release signed by a Servicing Officer and shall include a statement to the effect that all amounts received
or to be received in connection with such payment which are required to be deposited in the Collection Account pursuant to Section
3.04(a) or remitted to the Master Servicer to enable such deposit, have been or will be so deposited. Within seven (7)
Business Days (or within such shorter period as release can reasonably be accomplished if the Master Servicer or the Special
Servicer notifies the Custodian of an exigency) of receipt of such notice and request, the Custodian shall release the
related Mortgage File to the Master Servicer or the Special Servicer, as the case may be; provided that in the case of
the payment in full of a Serviced Companion Loan or its related Mortgage Loan, the related Mortgage File shall not be
released by the Custodian unless the related Serviced Whole Loan is paid in full. No expenses incurred in connection with any
instrument of satisfaction or deed of reconveyance shall be chargeable to the Collection Account.

 

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

 

(c)       Within
seven (7) Business Days (or within such shorter period as delivery can reasonably be accomplished if the Special Servicer notifies
the Trustee of an exigency) of receipt thereof, the Trustee shall execute and deliver to the Special Servicer any court pleadings,
requests for trustee’s sale or other documents necessary to the foreclosure or trustee’s sale in respect of a Mortgaged
Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note (including any note evidencing
a related Companion Loan) or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided

 

     -205-

     

    

 

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

 

(d)       If,
from time to time, pursuant to the terms of the applicable Non-Serviced Intercreditor Agreement and the applicable Non-Serviced
PSA, and as appropriate for enforcing the terms of a Non-Serviced Mortgage Loan, the applicable Non-Serviced Master Servicer requests
delivery to it of the original Mortgage Note for a Non-Serviced Mortgage Loan, then the Custodian shall release or cause the release
of such original Mortgage Note to such Non-Serviced Master Servicer or its designee.

 

Section
3.11     Servicing Compensation. (a) As compensation for its activities hereunder, the Master
Servicer shall be entitled to receive the Servicing Fee with respect to each Mortgage Loan, Serviced Companion Loan and REO
Loan (other than the portion of any REO Loan related to any Non-Serviced Companion Loan) (including Specially Serviced Loans
and any Non-Serviced Mortgage Loan constituting a “specially serviced loan” under any related Non-Serviced PSA).
As to each Mortgage Loan, Companion Loan and REO Loan, the Servicing Fee shall accrue from time to time at the Servicing Fee
Rate and shall be computed on the basis of the Stated Principal Balance of such Mortgage Loan, Companion Loan or REO Loan, as
the case may be, and in the same manner as interest is calculated on such Mortgage Loan, Companion Loan or REO Loan, as the
case may be, and, in connection with any partial month interest payment, for the same period respecting which any related
interest payment due on such Mortgage Loan or Companion Loan or deemed to be due on such REO Loan is computed. The Servicing
Fee with respect to any Mortgage Loan, Companion Loan or REO Loan shall cease to accrue if a Liquidation Event occurs with
respect to the related Mortgage Loan, except that if such Mortgage Loan is part of a Serviced Whole Loan and such Serviced
Whole Loan continues to be serviced and administered under this Agreement notwithstanding such Liquidation Event, then the
applicable Servicing Fee shall continue to accrue and be payable as if such Liquidation Event did not occur. The Servicing
Fee shall be payable monthly, on a loan-by-loan basis, from payments of interest on each Mortgage Loan, Companion Loan and
REO Revenues allocable as interest on each REO Loan, and as otherwise provided by Section 3.05(a). The Master
Servicer shall be entitled to recover unpaid Servicing Fees in respect of any Mortgage Loan, Companion Loan or REO Loan out
of that portion of related payments, Insurance and Condemnation Proceeds, Liquidation Proceeds and REO Revenues (in the case
of an REO Loan) allocable as recoveries of interest, to the extent permitted by Section 3.05(a).

 

Except as set forth in
the following sentence, the fourth (4th) paragraph of this Section 3.11(a), Section 6.03, Section 6.05 and
Section 7.01(c), the right to receive the Servicing Fee may not be transferred in whole or in part (except in connection
with a transfer of all of the Master Servicer’s duties and obligations hereunder to a successor servicer in accordance with
the terms hereof). With respect to each Serviced Pari Passu Companion Loan, the Servicing Fee

 

     -206-

     

    

 

shall
be payable to the Master Servicer from amounts payable in respect of such Serviced Pari Passu Companion Loan, subject to the terms
of the related Intercreditor Agreement.

 

The Master Servicer shall
be entitled to retain, and shall not be required to deposit in the Collection Account pursuant to Section 3.04(a), additional
servicing compensation (other than with respect to a Non-Serviced Mortgage Loan) in the form of the following amounts to the extent
collected from the related Mortgagor:

 

(i) 100% of Excess Modification
Fees related to any modifications, waivers, extensions or amendments of any Non-Specially Serviced Loans (including any related
Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) that are Master Servicer Decisions;
and for any matter for a Mortgage Loan (including any related Companion Loan) that is not a Specially Serviced Loan which matter
involves a Major Decision or a Special Servicer Decision, then the Master Servicer shall be entitled to 50% of such Excess Modification
Fees,

 

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

 

(iii) 100% of assumption,
waiver, consent and earnout fees, and other similar fees (other than assumption application and defeasance fees) pursuant to Section
3.08 and Section 3.18 or other actions performed in connection with this Agreement on the Non-Specially Serviced Loans
(including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) relating to
Master Servicer Decisions; and for any matter for a Mortgage Loan (including any related Companion Loan) that is not a Specially
Serviced Loan which matter involves a Major Decision or a Special Servicer Decision, then the Master Servicer shall be entitled
to 50% of such assumption, waiver, consent and earnout fees and other similar fees.

 

In addition, the Master
Servicer shall be entitled to charge and retain as additional servicing compensation (other than with respect to any Non-Serviced
Mortgage Loan or Specially Serviced Loan) any charges for beneficiary statements or demands and other customary charges, amounts
collected for checks returned for insufficient funds and reasonable review fees in connection with any Mortgagor request to the
extent such review fees are not prohibited under the related Mortgage Loan documents, in each case only to the extent actually
paid by or on behalf of the related Mortgagor and shall not be required to deposit such amounts in the Collection Account or the
Companion Distribution Account pursuant to Section 3.04(a) or Section 3.04(b), respectively. Subject to Section
3.11(d), the Master Servicer shall also be entitled to additional servicing compensation in the form of: (i) Penalty Charges
to the extent provided in Section 3.11(d), (ii) interest or other income earned on deposits relating to the Trust Fund in
the Collection Account or the Companion Distribution Account in accordance with Section 3.06(b) (but only to the extent
of the Net Investment Earnings, if any, with respect to

 

     -207-

     

    

 

such
account for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the
current Distribution Date), (iii) interest or other income earned on deposits in its Servicing Accounts which are not required
by applicable law or the related Mortgage Loan to be paid to the Mortgagor, and (iv) the difference, if positive, between Prepayment
Interest Excesses and Prepayment Interest Shortfalls collected on the Mortgage Loans and any Serviced Pari Passu Companion Loan,
during the related Collection Period to the extent not required to be paid as Compensating Interest Payments. The Master Servicer
shall be required to pay out of its own funds all expenses incurred by it in connection with its servicing activities hereunder
(including, without limitation, payment of any amounts due and owing to any of its Sub-Servicers and the premiums for any blanket
Insurance Policy insuring against hazard losses pursuant to Section 3.07), if and to the extent such expenses are not payable
directly out of the Collection Account and the Master Servicer shall not be entitled to reimbursement therefor except as expressly
provided in this Agreement.

 

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

 

Notwithstanding anything
herein to the contrary, Wells Fargo Bank, National Association may, at its option, assign or pledge to any third party or retain
for itself the Transferable Servicing Interest with respect to any Mortgage Loan and any Serviced Pari Passu Companion Loan (and
any successor REO Loan); provided, however, that in the event of any resignation or termination of the Master Servicer,
all or any portion of the Transferable Servicing Interest may be reduced by the Trustee to the extent reasonably necessary (in
the sole discretion of the Trustee) for the Trustee to obtain a qualified successor master servicer that meets the requirements
of Section 6.05 and who requires market-rate servicing compensation that accrues at a per annum rate in excess of
the Retained Fee Rate, and any such assignment of the Transferable Servicing Interest shall, by its terms be expressly subject
to the terms of this Agreement and such reduction. The Master Servicer shall pay the Transferable Servicing Interest to the holder
of the Transferable Servicing Interest at such time and to the extent the Master Servicer is entitled to receive payment of its
Servicing Fees hereunder, notwithstanding any resignation or termination of Wells Fargo Bank, National Association, as Master Servicer,
hereunder (subject to reduction pursuant to the preceding sentence).

 

     -208-

     

    

 

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

 

(c)       The
Special Servicer shall be entitled to additional servicing compensation in the form of

 

(i) 100% of all Excess
Modification Fees related to modifications, waivers, extensions or amendments of any Specially Serviced Loans,

 

(ii) 100% of all assumption
application fees and other similar items received with respect to Specially Serviced Loans and 100% of all assumption application
fees and other similar items received with respect to Mortgage Loans (other than Non-Serviced Mortgage Loans) and Serviced Companion
Loans that are Non-Specially Serviced Loans to the extent the Special Servicer processes the underlying transaction,

 

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

 

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

 

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

 

and shall be promptly
paid to the Special Servicer by the Master Servicer (or directly from the related Mortgagor) to the extent such fees are paid by
the Mortgagor and shall not be required to be deposited in the Collection Account pursuant to Section 3.04(a). Subject to
Section 3.11(d),

 

     -209-

     

    

 

the
Special Servicer shall also be entitled to additional servicing compensation in the form of: (i) Penalty Charges to the extent
provided in Section 3.11(d) and (ii) interest or other income earned on deposits relating to the Trust Fund in the REO
Account and Loss of Value Reserve Fund in accordance with Section 3.06(b) (but only to the extent of the Net Investment
Earnings, if any, with respect to such account for the period from and including the prior Distribution Date to and including
the P&I Advance Date related to such Distribution Date). In addition, the Special Servicer shall be entitled to retain as
additional servicing compensation (other than with respect to any Non-Serviced Mortgage Loan) reasonable review fees in connection
with any Mortgagor request to the extent such review fees are not prohibited under the related Mortgage Loan documents, and only
to the extent actually paid by or on behalf of the related Mortgagor. The 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 received by the Special Servicer; provided, further, however,
that in the event the Workout Fee collected over the course of such workout calculated at the Workout Fee Rate is less than $25,000,
then the Special Servicer shall be entitled to an amount from the final payment on the related Corrected Loan (including any related
Serviced Companion Loan) that would result in the total Workout Fees payable to the Special Servicer in respect of that Corrected
Loan (including any related Serviced Companion Loan) being equal to $25,000. The Workout Fee shall be reduced (but not below zero)
with respect to each collection on such Corrected Loan from which fee would otherwise be payable until an amount equal to the
Excess Modification Fee Amount has been deducted in full. The Workout Fee with respect to any Corrected Loan will cease to be
payable if such loan again becomes a Specially Serviced Loan; provided that a new Workout Fee will become payable if and
when such Specially Serviced Loan again becomes a Corrected Loan. The Special Servicer shall not be entitled to any Workout Fee
with respect to a Non-Serviced Mortgage Loan. If the Special Servicer is terminated (other than for cause) or resigns, it shall
retain the right to receive any and all Workout Fees payable in respect of Mortgage Loans or any related Companion Loan that became
Corrected Loans prior to the time of that termination or resignation except the Workout Fees will no longer be payable if the
Corrected Loan subsequently becomes a Specially Serviced Loan. If the Special Servicer resigns or is terminated (other than for
cause), it will receive any Workout Fees payable on Specially Serviced Loans for which the resigning or terminated Special Servicer
had determined to grant a forbearance or cured the event of default through a modification, restructuring or workout negotiated
by the Special Servicer and evidenced by a signed writing, but which had not as of the time the Special Servicer resigned or was
terminated become a Corrected Loan solely because the Mortgagor had not had sufficient time to make three (3) consecutive timely
Periodic Payments and which subsequently becomes a Corrected Loan as a result of the Mortgagor making such three (3) consecutive
timely Periodic Payments. The successor special servicer will not be entitled to any portion of such Workout Fees. The Special
Servicer will not be entitled to receive any Workout Fees after termination for cause. A Liquidation Fee will be payable with
respect to (a) each Specially Serviced Loan (other than a Non-Serviced Mortgage Loan) or REO Property (other than a Non-Serviced
Mortgaged Property) as to which the Special Servicer receives any Liquidation Proceeds or Insurance and Condemnation Proceeds
and (b) each Mortgaged Loan repurchased by a Mortgage Loan Seller

 

     -210-

     

    

 

or for which a Loss of Value Payment was paid, in each case,
subject to the exceptions set forth in the definition of Liquidation Fee (such Liquidation Fee to be paid out of such Liquidation
Proceeds, Insurance and Condemnation Proceeds). If, however, Liquidation Proceeds or Insurance and Condemnation Proceeds are received
with respect to any Corrected Loan and the Special Servicer is properly entitled to a Workout Fee, such Workout Fee will be payable
based on and out of the portion of such Liquidation Proceeds and Insurance and Condemnation Proceeds that constitute principal
and/or interest on such Mortgage Loan. Notwithstanding anything herein to the contrary, the Special Servicer shall only be entitled
to receive a Liquidation Fee or a Workout Fee, but not both, with respect to proceeds on any Mortgage Loan. Notwithstanding the
foregoing, with respect to any Companion Loan, the Liquidation Fee, Workout Fee and Special Servicing Fees, if any, will be computed
as provided in the related Intercreditor Agreement or to the extent such Intercreditor Agreement is silent or refers to this Agreement
or indicates such fees are paid in accordance with this Agreement, as provided herein as though such Companion Loan were a Mortgage
Loan. Subject to Section 3.11(d), the Special Servicer will also be entitled to additional fees in the form of Penalty
Charges. The Special Servicer shall be required to pay out of its own funds all expenses incurred by it in connection with its
servicing activities hereunder (including, without limitation, payment of any amounts, other than management fees in respect of
REO Properties, due and owing to any of its Sub-Servicers and the premiums for any blanket Insurance Policy obtained by it insuring
against hazard losses pursuant to Section 3.07), if and to the extent such expenses are not expressly payable directly
out of the Collection Account or the REO Account, and the Special Servicer shall not be entitled to reimbursement therefor except
as expressly provided in this Agreement.

 

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

 

(d)       In
determining the compensation of the Master Servicer or the Special Servicer, as applicable, with respect to Penalty Charges, on
any Distribution Date, the aggregate Penalty Charges collected on any Mortgage Loan (other than a Non-Serviced Mortgage Loan) and
any related Companion Loan since the prior Distribution Date shall be applied (in such order) to reimburse (i) the Master Servicer,
the Special Servicer or the Trustee for interest on Advances on such Mortgage Loan or related Companion Loan, if applicable (and,
in connection with a Non-Serviced Mortgage Loan, the applicable Non-Serviced Master Servicer, the

 

     -211-

     

    

 

applicable
Non-Serviced Special Servicer or the applicable Non-Serviced Trustee for interest on the servicing advances made by any such party
with respect to a Non-Serviced Whole Loan pursuant to the applicable Non-Serviced PSA, to the extent not prohibited by the applicable
Non-Serviced Intercreditor Agreement) due on such Distribution Date, (ii) the Trust for all interest on Advances previously paid
to the Master Servicer or the Trustee pursuant to Section 3.05(a)(vi) (and, in connection with a Non-Serviced Mortgage
Loan, the related trust for all interest on servicing advances reimbursed by such trust to any party under the applicable Non-Serviced
PSA, which resulted in an additional expense for the Trust, to the extent not prohibited by the applicable Non-Serviced Intercreditor
Agreement) with respect to such Mortgage Loan or related Companion Loan, if applicable and (iii) the Trust for all additional
expenses of the Trust (other than Special Servicing Fees, Workout Fees and Liquidation Fees), including without limitation, inspections
by the Special Servicer and all unpaid Advances incurred since the Closing Date with respect to such Mortgage Loan. Penalty Charges
(other than with respect to a Non-Serviced Mortgage Loan, which shall be payable as additional servicing compensation under the
related Non-Serviced PSA) remaining thereafter shall be distributed to the Master Servicer, if and to the extent accrued while
such Mortgage Loan and any related Companion Loan was a Non-Specially Serviced Loan, and to the Special Servicer, if and to the
extent accrued on such Mortgage Loan during the period such Mortgage Loan was a Specially Serviced Loan or REO Loan. Any Penalty
Charges paid or payable as additional servicing compensation to the Master Servicer and the Special Servicer shall be distributed
between the Master Servicer and the Special Servicer, on a pro rata basis, based on the Master Servicer’s and the
Special Servicer’s respective entitlements to such compensation described in the previous sentence. Notwithstanding the
foregoing or anything else herein to the contrary, Penalty Charges with respect to any Companion Loan will be allocated pursuant
to the applicable Intercreditor Agreement after payment of all related Advances and interest thereon and additional expenses of
the Trust in accordance with this Section 3.11(d).

 

(e)       With
respect to each Distribution Date, the Special Servicer shall deliver or cause to be delivered to the Master Servicer within two
(2) Business Days following the Determination Date, and the Master Servicer shall deliver, to the extent it has received, to the
Certificate Administrator, without charge and on the related Remittance Date, an electronic report (which may include HTML, Word
or Excel compatible format, clean and searchable PDF format or such other format as mutually agreeable between the Certificate
Administrator and the Special Servicer) that discloses and contains an itemized listing of any Disclosable Special Servicer Fees
received by the Special Servicer or any of its Affiliates, if any, with respect to such Distribution Date; provided that
no such report shall be due in any month during which no Disclosable Special Servicer Fees were received.

 

(f)       The
Special Servicer and its Affiliates shall be prohibited from receiving or retaining any compensation or any other remuneration
(including, without limitation, in the form of commissions, brokerage fees, rebates, or as a result of any other fee-sharing arrangement)
from any Person (including, without limitation, the Trust, any Mortgagor, any property manager, any guarantor or indemnitor in
respect of a Mortgage Loan and any purchaser of any Mortgage Loan or REO Property) in connection with the disposition, workout
or foreclosure of any Mortgage Loan or Serviced Companion Loan, the management or disposition of any REO Property, or the performance
of any other special servicing duties under this

 

     -212-

     

    

 

Agreement,
other than as expressly provided in this Section 3.11; provided that such prohibition shall not apply to Permitted
Special Servicer/Affiliate Fees.

 

(g)       Pursuant
to the CREFC® License Agreement, CREFC® shall be paid (according to the payment instructions set
forth on Exhibit II hereto or such other payment instructions as CREFC® may provide to the Master Servicer
in writing at least two (2) Business Days prior to the Remittance Date) the CREFC® Intellectual Property Royalty
License Fee on a monthly basis. The Master Servicer shall withdraw from the Collection Account and, to the extent sufficient funds
are on deposit therein, pay the CREFC® Intellectual Property Royalty License Fee to CREFC® in accordance
with Section 3.05(a)(xii) on a monthly basis, from funds on deposit in the Collection Account.

 

Section
3.12     Inspections; Collection of Financial Statements. (a) The Master Servicer shall
perform (at its own expense), or shall cause to be performed (at its own expense), a physical inspection of each Mortgaged
Property relating to a Mortgage Loan (other than a Non-Serviced Mortgage Loan or a Specially Serviced Loan) with a Stated
Principal Balance of (i) $2,000,000 or more at least once every twelve (12) months and (ii) less than $2,000,000 at least
once every twenty-four (24) months, in each case, commencing in the calendar year 2018 (and each Mortgaged Property shall be
inspected on or prior to December 31, 2019); provided, however, that if a physical inspection has been
performed by the Special Servicer in the previous twelve (12) months, the Master Servicer will not be required to perform, or
cause to be performed, such physical inspection; provided, further, that if any scheduled payment becomes more
than sixty (60) days delinquent on the related Mortgage Loan, the Special Servicer shall inspect or cause to be inspected the
related Mortgaged Property as soon as practicable after such Mortgage Loan becomes a Specially Serviced Loan and annually
thereafter for so long as such Mortgage Loan remains a Specially Serviced Loan. The cost of such inspection by the Special
Servicer pursuant to the second proviso of the immediately preceding sentence shall be an expense of the Trust, and, to the
extent not paid by the related Mortgagor, reimbursed first from Penalty Charges actually received from the related
Mortgagor and then from the Collection Account pursuant to Section 3.05(a)(ii), provided that, with respect to
a Serviced Whole Loan, such cost shall be payable, subject to the terms of the related Intercreditor Agreement (i) with
respect to a Serviced Pari Passu Whole Loan, pro rata and pari passu, from the related Serviced Pari Passu
Mortgage Loan and Serviced Pari Passu Companion Loan, in accordance with their respective outstanding principal balances, or
(ii) with respect to a Serviced AB Whole Loan, first, from the related AB Subordinate Companion Loan(s) and then,
from the Serviced AB Mortgage Loan and any Serviced Pari Passu Companion Loans on a pro rata and pari passu basis
(provided that, with respect to any AB Subordinate Companion Loan, the foregoing shall not limit or otherwise modify
the terms of the related Intercreditor Agreement pursuant to which any amounts collected with respect to the related Whole
Loan are allocated to the related Serviced AB Mortgage Loan, any Serviced Pari Passu Companion Loans and the AB Subordinate
Companion Loans), in each case, prior to being payable out of general collections. The Special Servicer or the Master
Servicer, as applicable, shall prepare or cause to be prepared a written report of each such inspection detailing the
condition of and any damage to the Mortgaged Property to the extent evident from the inspection and specifying the existence
of (i) any vacancy at the Mortgaged Property that the preparer of such report has knowledge of and the Master Servicer or the
Special Servicer, as the case may be, deems material, (ii) any sale, transfer or abandonment of the Mortgaged Property of
which the preparer of such report has

 

     -213-

     

    

 

knowledge
or that is evident from the inspection, (iii) any adverse change in the condition of the Mortgaged Property of which the preparer
of such report has knowledge or that is evident from the inspection, and that the Master Servicer or the Special Servicer, as
the case may be, deems material, (iv) any visible material waste committed on the Mortgaged Property of which the preparer of
such report has knowledge or that is evident from the inspection and (v) photographs of each inspected Mortgaged Property. The
Special Servicer and the Master Servicer shall promptly following preparation deliver or make available a copy (in electronic
format) of each such report prepared by the Special Servicer and the Master Servicer, respectively, to the other party, to the
Directing Certificateholder ((i) prior to the occurrence and continuance of a Control Termination Event and (ii) other than with
respect to any Excluded Loan (as to such party) that is a Specially Serviced Loan). Within five (5) Business Days after request
for copies of such reports by the Rating Agencies, the Special Servicer or the Master Servicer, as applicable, shall deliver or
make available a copy (in electronic format) of each such report prepared by the Special Servicer and the Master Servicer, as
applicable, to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website for review by NRSROs
(including the Rating Agencies) that are Privileged Persons. The Master Servicer shall deliver or make available a copy of each
such report to the Directing Certificateholder and upon request to each Controlling Class Certificateholder (which request may
state that such items may be delivered until further notice) (except, after the occurrence and during the continuance of a Consultation
Termination Event or with respect to any Specially Serviced Loan that is an Excluded Loan as to such party).

 

(b)       The
Special Servicer, in the case of any Specially Serviced Loan, and the Master Servicer, in the case of any Non-Specially Serviced
Loan shall make reasonable efforts to collect promptly and review from each related Mortgagor quarterly and annual operating statements,
financial statements, budgets and rent rolls of the related Mortgaged Property, and the quarterly and annual financial statements
of such Mortgagor, whether or not delivery of such items is required pursuant to the terms of the related Mortgage Loan documents
and any other reports or documents required to be delivered under the terms of the Mortgage Loans (and each Serviced Companion
Loan), if delivery of such items is required pursuant to the terms of the related Mortgage Loan documents. The Master Servicer
and the Special Servicer shall not be required to request such operating statements or rent rolls more than once if the related
Mortgagor is not required to deliver such statements pursuant to the terms of the Mortgage Loan documents. In addition, the Special
Servicer shall cause quarterly and annual operating statements, budgets and rent rolls to be regularly prepared in respect of each
REO Property and shall collect all such items promptly following their preparation. The Special Servicer shall deliver all such
items to the Master Servicer within five (5) Business Days of receipt, and the Master Servicer and the Special Servicer, as applicable,
shall deliver or make available copies of all the foregoing items so collected to the Trustee, the Certificate Administrator, the
Directing Certificateholder and the Depositor, in electronic format, in each case within sixty (60) days of its receipt thereof,
but in no event, in the case of annual statements, later than June 30 of each year commencing 2018. Upon the request of any Privileged
Person (other than the NRSROs) to receive copies of such items, the Master Servicer (with respect to Non-Specially Serviced Loans)
or the Special Servicer (with respect to Specially Serviced
Loans and REO Loans) shall deliver or make available electronic copies of such items to the Certificate Administrator to be posted
on the Certificate Administrator’s Website. Upon the request of any NRSRO, the Master Servicer (with respect to Non-Specially
Serviced Loans) or the Special Servicer (with respect to Specially 

 

     -214-

     

    

 

Serviced Loans and REO Loans) shall deliver copies of all or
any portion of the foregoing items so collected thereby to the 17g-5 Information Provider pursuant to Section 3.13(c).

 

In addition, the Master
Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans that
are not, and REO Properties that do not relate to, Non-Serviced Mortgage Loans), as applicable, shall prepare with respect to each
Mortgaged Property securing a Mortgage Loan (other than a Non-Serviced Mortgage Loan) and REO Property:

 

(i)        Within
forty-five (45) days after receipt of a quarterly operating statement, if any, commencing within forty-five (45) days of receipt
of such quarterly operating statement for the quarter ending September 30, 2017, a CREFC® Operating Statement Analysis
Report (but only to the extent the related Mortgagor is required by the related Mortgage Loan documents to deliver and does deliver,
or otherwise agrees to provide and does provide, such information) for such Mortgaged Property or REO Property as of the end of
that calendar quarter, provided, however, that any analysis or report with respect to the first calendar quarter
of each year will not be required to the extent provided in the then-current applicable CREFC® guidelines (it being
understood that as of the Closing Date, the applicable CREFC® guidelines provide that such analysis or report with
respect to the first calendar quarter (in each year) is not required for a Mortgaged Property or REO Property unless such Mortgaged
Property or REO Property is analyzed on a trailing twelve (12) month basis, or if the related Serviced Mortgage Loan is on the
CREFC® Servicer Watch List). The Master Servicer (with respect to Non-Specially Serviced Loans) or the Special
Servicer (with respect to Specially Serviced Loans and REO Properties) shall deliver or make available copies (in electronic format)
of each CREFC® Operating Statement Analysis Report and, upon request, the related operating statements (in each
case, promptly following the initial preparation and each material revision thereof) to the Certificate Administrator, the Directing
Certificateholder and the related Companion Holder (with respect to any Serviced Companion Loan).

 

(ii)       Within
forty-five (45) days after receipt of an annual operating statement or rent rolls (if and to the extent any such information is

as recommended by CREFC® in the instructions to the CREFC® guidelines) for each calendar year commencing
within forty-five (45) days of receipt of such annual operating statement for the calendar year ending December 31, 2017, a CREFC®

the CREFC® Comparative Financial Status Report. The Master Servicer (with respect to Non-Specially Serviced Loans)

electronic format) of each CREFC® NOI Adjustment Worksheet and, upon request, the related operating statements or rent rolls
(in each case, promptly following the initial preparation and each material revision

 

     -215-

     

    

 

thereof)
to the Certificate Administrator, the Directing Certificateholder and the related Companion Holder (with respect to any Serviced
Companion Loan).

 

(c)       At
or before 12:00 p.m. (New York City time) on each Determination Date, the Special Servicer shall prepare and deliver or cause to

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

 

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

 

(e)       The
Special Servicer shall deliver to the Master Servicer the reports and information required of the Special Servicer pursuant to
Section 3.12(b) and Section 3.12(c), and the Master Servicer shall deliver or make available to the Certificate Administrator
the reports and data files set forth in Section 3.12(d). The Master Servicer may, absent manifest error, conclusively rely
on the reports and/or data to be provided by the Special Servicer pursuant to Section 3.12(b) and Section 3.12(c).
The Certificate Administrator may, absent manifest error, conclusively rely on the reports and/or data to be provided by the Master
Servicer pursuant to Section 3.12(d). In the case of information or reports to be furnished by the Master Servicer to the
Certificate Administrator pursuant to Section 3.12(d), to the extent that such information or reports are, in turn, based
on information or reports to be provided by the Special Servicer pursuant to Section 3.12(b) or Section 3.12(c) and
to the extent that such reports are to be prepared and delivered by the Special Servicer pursuant to Section 3.12(b) or
Section 3.12(c), the Master Servicer shall have no obligation to provide such information or reports to the Certificate
Administrator until it has received the requisite information or reports from the Special Servicer,

 

     -217-

     

    

 

and
the Master Servicer shall not be in default hereunder due to a delay in providing the reports required by Section 3.12(d)
caused by the Special Servicer’s failure to timely provide any information or report required under Section 3.12(b)
or Section 3.12(c) of this Agreement.

 

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

 

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

 

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

 

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

 

     -218-

     

    

 

applicable
law. At the election of the Master Servicer, the Special Servicer or the Certificate Administrator, such access may be afforded
to such Person identified above by the delivery of copies of information as requested by such Person and the Master Servicer,
the Special Servicer or the Certificate Administrator shall be permitted to require payment (other than from the Directing Certificateholder
and the Trustee and the Certificate Administrator on its own behalf or on behalf of the Certificateholders, as applicable) of
a sum sufficient to cover the reasonable out-of-pocket costs incurred by it in making such copies. Such access shall (except as
described in the preceding sentence) be afforded without charge but only upon reasonable prior written request and during normal
business hours at the offices of the Certificate Administrator or the Custodian.

 

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

 

Notwithstanding the limitation
set forth in the next succeeding paragraph, upon the reasonable request of any Certificateholder (or with respect to any AB Subordinate
Companion Loan related to a Serviced AB Whole Loan, the holder of such AB Subordinate Companion Loan) that has delivered an Investor
Certification to the Master Servicer or the Special Servicer, as the case may be, the Master Servicer (with respect to Non-Specially
Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans), as applicable, may provide (or make available
electronically) or make available at the expense of such Certificateholder or holder of such AB Subordinate Companion Loan, as
applicable, copies of any appraisals, operating statements, rent rolls and financial statements (in each case, solely

relating
to the related Serviced Whole Loan or Serviced AB Whole Loan, if requested by the holder of an AB Subordinate Companion Loan,
as the case may be) obtained by the Master Servicer or the Special Servicer, as the case may be; provided that, in connection
with such request, the Master Servicer or the Special Servicer, as applicable, may require a written confirmation executed by
the requesting Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special Servicer,
as applicable, generally to the effect that such Person will keep such information confidential and shall use such information
only for the purpose of analyzing asset performance and evaluating any continuing rights the Certificateholder or holder of such
AB Subordinate Companion Loan, as applicable, may have under this Agreement.

 

Notwithstanding anything
to the contrary herein (other than as permitted in the preceding paragraph with respect to any Certificateholder or as specifically
provided for herein with respect to the Directing Certificateholder), unless required by applicable law or court order, no Certificateholder
(except, with respect to a Mortgage Loan Seller, to the extent necessary for such party to comply with its obligations under the
related Mortgage Loan Purchase Agreement, and except for the Master Servicer and the Certificate Administrator, acting in such
capacities) or beneficial owner shall be given access to, or be provided copies of, the Mortgage Files or Diligence Files.

The Certificate Administrator
shall post on the Certificate Administrator’s Website the items and reports identified in clauses (iii)(A) and (B)

Notwithstanding the foregoing,
all Excluded Information shall be made available under a separate tab or heading designated “Excluded Information”
on the Certificate Administrator’s Website (and not under any of the tabs or headings described in items (i) through

Party (unless a loan-by-loan segregation is later performed by the Certificate Administrator in which case such access shall only

     -223-

     

    

 

the
Operating Advisor, the Certificate Administrator and the Trustee in physical form (or, solely with respect to the Master Servicer,
in electronic form) of an investor certification substantially in the form of Exhibit P-1D and upon delivery to the Certificate
Administrator in physical form of an investor certification substantially in the form of Exhibit P-1F, which shall include
each of the CTSLink User ID associated with such Excluded Controlling Class Holder, all information (other than the Excluded Information
with respect to any Excluded Controlling Class Loans (unless a loan-by-loan segregation is later performed by the Certificate

available on the Certificate Administrator’s Website.

 

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

 

Notwithstanding anything
herein to the contrary, each of the Master Servicer, the Special Servicer, the Operating Advisor and the Certificate Administrator
shall be entitled to

 

     -224-

     

    

 

conclusively
assume that the Directing Certificateholder and all beneficial owners of the Certificates of the Controlling Class are not Excluded
Controlling Class Holders except to the extent that the Master Servicer, the Special Servicer, the Operating Advisor or the Certificate
Administrator, as the case may be, has received a notice substantially in the form of Exhibit P-1E from the Directing Certificateholder
or a Controlling Class Certificateholder that it has become an Excluded Controlling Class Holder. None of the Master Servicer,
the Special Servicer, the Operating Advisor or the Certificate Administrator shall be liable for any communication to the Directing
Certificateholder or a Controlling Class Certificateholder that is an Excluded Controlling Class Holder or disclosure of any information
relating to an Excluded Controlling Class Loan (including any related Excluded Information delivered to the Certificate Administrator
for posting to the Certificate Administrator’s Website) if the Master Servicer, the Special Servicer, the Operating Advisor
or the Certificate Administrator, as the case may be, did not receive prior written notice that the related Mortgage Loan is an
Excluded Controlling Class Loan and/or, with respect to any related Excluded Information posted on the Certificate Administrator’s
Website, such information was not delivered to the Certificate Administrator in accordance with Section 3.33.

 

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

 

To the extent the Risk
Retention Consultation Party or a Holder of an RR Interest receives access pursuant to this Agreement to any information solely
related to a Mortgage Loan with respect to which such party is a Borrower Party (which shall include any Asset Status Reports,
Final Asset Status Reports (or summaries thereof), inspection reports related to Specially Serviced Loans conducted by the Special
Servicer or any Excluded Special Servicer and which may include any Operating Advisor reports delivered to the Certificate Administrator
regarding the Special Servicer’s net present value determination or any Appraisal Reduction Amount calculations delivered
pursuant to Section 3.26(d) and Section 3.26(e), and any Officer’s Certificates delivered by the Trustee, the
Master Servicer or the Special Servicer, supporting any determination that any Advance was (or, if made, would be) a Nonrecoverable
Advance, but in each case other than information with respect to such Mortgage Loan that is aggregated with 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

 

     -225-

     

    

 

Holder
of an RR Interest shall be deemed to have agreed that it (i) will not directly or indirectly provide any such information to (A)
the related Borrower Party, (B) any employees or personnel of such Risk Retention Consultation Party or Holder of an RR Interest
or any of its Affiliates involved in the management of any investment in the related Borrower Party or the related Mortgaged Property
or (C) to its actual knowledge, any non-Affiliate that holds a direct or indirect ownership interest in the related Borrower Party,
and (ii) will maintain sufficient internal controls and appropriate policies and procedures in place in order to comply with the
obligations described in clause (i) above. For the avoidance of doubt, any file or report contained in the CREFC®
Investor Reporting Package (CREFC® IRP) (other than the CREFC® Special Servicer Loan File
relating to any such Excluded Loan) shall be considered information that is aggregated with information of other Mortgage Loans
at a pool level. For avoidance of doubt, the covenants and restrictions in this paragraph are not applicable to Wells Fargo Bank,
National Association, acting in its capacity as Master Servicer.

 

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 and assumes no responsibility therefor, other than with respect to such reports, documents or other information
prepared by the Certificate Administrator. In addition, the Certificate Administrator may disclaim responsibility for any information
distributed by it for which it is not the original source. Notwithstanding anything herein to the contrary, the Certificate Administrator
shall not be liable for any disclosure of information relating to any Excluded Controlling Class Loan to the extent such information
was included in any Asset Status Report or Final Asset Status Report inadvertently delivered to the Certificate Administrator for
posting to the Certificate Administrator’s Website and not properly identified as relating to any Excluded Controlling Class
Loan.

(f)       The
Master Servicer and the Special Servicer may, in accordance with such reasonable rules and procedures as it may adopt, also deliver,
produce or otherwise make available through its website or otherwise, any additional information relating to the Mortgage Loans
(other than any Non-Serviced Mortgage Loan), any related Serviced Companion Loan, the Mortgaged Properties (other than any Non-Serviced
Mortgaged Property), or the related Mortgagors, for review by the Depositor, the Underwriters and any other Persons who deliver

delivered to the 17g-5 Information Provider for posting on the 17g-5 Information Provider’s Website in accordance with the
provisions of Section 3.13(c)), in each case, except to the extent doing so is prohibited by this Agreement (including without
limitation, any prohibitions on dissemination of any confidential information, including, without limitation, any Privileged Information),
applicable law or by the related Mortgage Loan documents. The Master Servicer and the Special Servicer shall be entitled to (i)

nature of such information. In connection with providing access to or copies of the information described in this Section 3.13(f)
to current or prospective Certificateholders, the form of confidentiality agreement used by the Master Servicer or the Special
Servicer, as applicable, shall be: (i) in the case of a Certificateholder, an Investor Certification executed by the requesting
Person indicating that such Person is a Holder of Certificates and will keep such information confidential (except that such Certificateholder
may provide such information (x) to its auditors, legal counsel and regulators and (y) to any other Person that holds or is contemplating
the purchase of any Certificate or interest therein (provided that such other Person confirms in writing such ownership
interest or prospective ownership interest and agrees to keep such information confidential)); and (ii) in the case of a prospective
purchaser of Certificates or interests therein or an investment advisor related thereto, an Investor Certification indicating that
such Person is a prospective purchaser of a Certificate or an interest therein or an investment advisor related thereto and is
requesting the information for use in evaluating a possible investment in Certificates and will otherwise keep such information
confidential with no further dissemination (except that such Certificateholder may provide such information to its auditors, legal
counsel and regulators). In the case of a licensed or registered investment advisor acting on behalf of a current or prospective
Certificateholder, the Investor

Certification
shall be executed and delivered by both the investment advisor and such current or prospective Certificateholder.

 

Neither the Master Servicer
nor the Special Servicer shall be liable for its dissemination of information in accordance with this Agreement or by others in
violation of the terms of this Agreement. Neither the Master Servicer nor the Special Servicer shall be responsible or have any
liability for the completeness or accuracy of the information delivered, produced or otherwise made available pursuant to this
Section 3.13 unless such information was produced by the Master Servicer or the Special Servicer, as the case may be.

 

(g)       The
Master Servicer, the Special Servicer, the Certificate Administrator and the Trustee shall be permitted (but not obligated) 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
writing and provides the 17g-5 Information Provider with such written summary in accordance with the procedures set forth in Section
3.13(c) the same day such communication takes place; provided, further that the summary of such oral communications
shall not identify which Rating Agency the communication was with. The 17g-5 Information Provider shall post such written summary
on the 17g-5 Information Provider’s Website in accordance with the procedures set forth in Section 3.13(c).

 

(h)       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 available to the Directing Certificateholder or the Risk Retention Consultation
Party (in each case, other than, prior to the occurrence and continuance of a Control Termination Event, any Asset Status 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.

 

(i)        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 the case may be, (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 commercial mortgage master,
special or primary servicer, or (iii) such Rating Agency’s or NRSRO’s evaluation of the Master Servicer’s, the
Operating Advisor, the Asset Representations Reviewer’s or the Special Servicer’s, as the case may be, 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

 

     -231-

     

    

 

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

 

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

 

Section
3.14     Title to REO Property; REO Account. (a) If title to any Mortgaged Property is
acquired (directly or through a single member limited liability company established for that purpose) and thus becomes REO
Property, the deed or certificate of sale shall be issued in the name of the Trust where permitted by applicable law or
regulation and consistent with customary servicing procedures, and otherwise, in the name of the Trustee or its nominee on
behalf of the Certificateholders and, if applicable, on behalf of the related Companion Holders, in the case of a Serviced
Companion Loan. REO Property with respect to a Non-Serviced Mortgage Loan is excluded for all purposes of this Section
3.14. The Special Servicer, on behalf of the Trust and, if applicable, the related Serviced Companion Noteholder, shall
sell any REO Property prior to the close of the third calendar year following the year in which the Trust acquires ownership
of such REO Property, within the meaning of Treasury Regulations Section 1.856-6(b)(1), for purposes of Section 860G(a)(8) of
the Code, unless the Special Servicer either (i) applies for a qualifying extension of time no later than sixty (60) days
prior to the close of the third calendar year in which it acquired ownership (or the period provided in the then-applicable
REMIC Provisions) and such extension is granted or is not denied (an “REO Extension”) by the Internal
Revenue Service to sell such REO Property or (ii) obtains for the Trustee and the Certificate Administrator an Opinion of
Counsel, addressed to the Trustee and the Certificate Administrator, to the effect that the holding by the Trust of such REO
Property subsequent to the close of the third calendar year following the year in which acquisition occurred will not cause
an Adverse REMIC Event. If the Special Servicer is granted or not denied the REO Extension contemplated by clause
(i) of the immediately preceding sentence or obtains the Opinion of Counsel contemplated by clause (ii) of the
immediately preceding sentence, the Special Servicer shall sell such REO Property within such longer period as is permitted
by such REO Extension or such Opinion of Counsel, as the case may be. Any expense incurred by the Special Servicer in
connection with its being granted the REO Extension contemplated by clause (i) of the second preceding sentence or its
obtaining the Opinion of Counsel contemplated by clause (ii) of the second preceding sentence, shall be an expense of
the Trust payable out of the Collection Account pursuant to Section 3.05(a).

 

(b)       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

 

     -232-

     

    

 

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,
prior to each Determination Date, all REO Revenues, Insurance and Condemnation Proceeds and Liquidation Proceeds received in respect
of an REO Property. Funds in the REO Account may be invested in Permitted Investments in accordance with Section 3.06.
The Special Servicer shall give notice to the Trustee, the Certificate Administrator, and the Master Servicer of the location
of the REO Account when first established and of the new location of the REO Account prior to any change thereof.

 

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

 

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

 

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

 

     -233-

     

    

 

things
in connection therewith as are in the best interests of and for the benefit of the Certificateholders (and, in the case of each
Serviced Whole Loan, the related Companion Holder(s)) and the Trustee (as holder of the Lower-Tier Regular Interests) all as a
collective whole (taking into account the subordinate or pari passu nature of any Companion Loan, as the case may be) (as
determined by the Special Servicer in its reasonable judgment in accordance with the Servicing Standard). Notwithstanding anything
to the contrary herein, REO Property with respect to a Non-Serviced Mortgage Loan is excluded for all purposes of this Section
3.15. Subject to this Section 3.15, the Special Servicer may allow the Trust or any commercial mortgage securitization
that holds any Serviced Companion Loan to earn “net income from foreclosure property” within the meaning of Section
860G(d) of the Code if it determines that earning such income is in the best interests of Certificateholders and, if applicable,
any related Companion Holder(s) on a net after-tax basis as compared with net leasing such REO Property or operating such REO
Property on a different basis. In connection therewith, the Special Servicer shall deposit or cause to be deposited on a daily
basis (and in no event later than two (2) Business Days following receipt of such properly identified funds) in the REO Account
all revenues received by it with respect to each REO Property and the related REO Loan, and shall withdraw from the REO Account,
to the extent of amounts on deposit therein with respect to such REO Property, funds necessary for the proper operation, management,
leasing and maintenance of such REO Property, including, without limitation:

 

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

 

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

 

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

 

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

 

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

 

     -234-

     

    

 

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

 

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

 

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

 

unless, in any such case, the Special Servicer
has obtained an Opinion of Counsel (the cost of which shall be paid by the Master Servicer as a Servicing Advance) to the effect
that such action will not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of
Section 860G(a)(8) of the Code at any time that it is held for the benefit of the Trust, in which case the Special Servicer may
take such actions as are specified in such Opinion of Counsel.

 

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

 

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

 

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

 

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

 

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

 

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

 

The Special Servicer
shall be entitled to enter into any agreement with any Independent Contractor performing services for it related to its duties
and obligations hereunder for indemnification of the Special Servicer by such Independent Contractor, and nothing in this Agreement
shall be deemed to limit or modify such indemnification.

 

     -235-

     

    

 

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

 

Section 3.16     Sale
of Defaulted Loans and REO Properties. (a) (i) Within thirty (30) days after a Defaulted Loan has become a Specially Serviced
Loan, the Special Servicer shall order (but shall not be required to have received) an Appraisal and within thirty (30) days of
receipt of the Appraisal shall determine the fair value of such Defaulted Loan in accordance with the Servicing Standard; provided,
however, that if the Special Servicer is then in the process of obtaining an Appraisal with respect to the related Mortgaged
Property, the Special Servicer shall make its fair value determination as soon as reasonably practicable (but in any event within
thirty (30) days) after its receipt of such an Appraisal. The Special Servicer may, from time to time, adjust its fair value determination
based upon changed circumstances, new information and other relevant factors, in each instance in accordance with a review of
such circumstances and new information in accordance with the Servicing Standard including, without limitation, the period and
amount of the occupancy level and physical condition of the related Mortgaged Property and the state of the local economy; provided
that the Special Servicer shall promptly notify the Master Servicer in writing of the initial fair value determination and
any adjustment to its fair value determination.

 

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

 

(iii)      If
any Mortgage Loan not subject to an Intercreditor Agreement becomes a Specially Serviced Loan, or if the related Companion Holder
or related mezzanine lender, as applicable, for any such Mortgage Loan subject to an Intercreditor Agreement has not previously
exercised the option to purchase the Mortgage Loan pursuant to the previous paragraph, the Special Servicer shall use reasonable
efforts to solicit offers for each Defaulted Loan on behalf of the Certificateholders and the holder of any related Serviced Companion
Loan in such manner as will be reasonably likely to maximize the value of the Defaulted Loan on a net present value basis, if
and when the Special Servicer determines, consistent with the Servicing Standard, that no satisfactory arrangements (including
by way of a discounted pay-off) can be made for collection of delinquent payments thereon and such a sale would be in the best
economic interests of the Trust

 

     -236-

     

    

 

and,
if applicable, the related Companion Holder. In the case of a Non-Serviced Mortgage Loan, to the extent permitted under the related
Intercreditor Agreement, and such Non-Serviced Mortgage Loan is not sold together with the Non-Serviced Companion Loan by the
Non-Serviced Special Servicer, the Special Servicer will be entitled to sell ((i) with the consent of the Directing Certificateholder
if no Control Termination Event has occurred and is continuing and (ii) after consulting with the Risk Retention Consultation
Party pursuant to Section 6.08(a), in each case, provided such Non-Serviced Mortgage Loan is not an Excluded Loan as to
such party) such Non-Serviced Mortgage Loan if it determines in accordance with the Servicing Standard that such action would
be in the best interests of the Certificateholders and, subject to the terms of the related Intercreditor Agreement (and provided
that the related Non-Serviced Special Servicer will not be entitled to a liquidation fee), the Special Servicer will be entitled
to the liquidation fee that the related Non-Serviced Special Servicer would have otherwise been entitled to in connection with
the sale of such Non-Serviced Mortgage Loan. The Special Servicer is required to give the Trustee, the Certificate Administrator,
the Master Servicer, the Operating Advisor and the Directing Certificateholder and the Risk Retention Consultation Party (in the
case of the Directing Certificateholder and the Risk Retention Consultation Party, other than in respect of any Excluded Loan
as to such party) not less than ten (10) days’ prior written notice of its intention to sell any Defaulted Loan. In the
absence of a cash offer at least equal to the Purchase Price, the Special Servicer may purchase the Defaulted Loan for the Purchase
Price or may accept the first cash offer received from any Person that constitutes a fair price for the Defaulted Loan.

 

(iv)     (A)
In the case of a Specially Serviced Loan as to which a default has occurred and is continuing, in the absence of any offer at
least equal to the Purchase Price pursuant to clause (iii) above (or purchase by the Special Servicer for such price),
the Special Servicer shall solicit offers and, subject to sub-clause (B) below, accept the highest offer received from
any Person that is determined by the Special Servicer to be a fair price for such Specially Serviced Loan, if the offeror is
a Person other than an Interested Person. In determining whether any offer from a Person other than an Interested Person
constitutes a fair price for any Defaulted Loan, the Special Servicer shall take into account (in addition to the results of
any Appraisal, updated Appraisal or narrative appraisal that it may have obtained pursuant to this Agreement within the prior
nine (9) months), among other factors, the period and amount of the occupancy level and physical condition of the related
Mortgaged Property and the state of the local economy. If the offeror is an Interested Person (provided that the
Trustee may not be an offeror), the Trustee shall determine whether the offer constitutes a fair price unless such offer by
an Interested Person (i) is equal to or greater than the applicable Purchase Price and (ii) is the highest offer received.
Absent an offer at least equal to the Purchase Price, no offer from an Interested Person shall constitute a fair price unless
(x) it is the highest offer received and (y) at least two (2) other offers are received from independent third parties. In
determining whether any offer received from an Interested Person represents a fair price for any such Defaulted Loan, the
Trustee shall rely on the most recent Appraisal (or update of such Appraisal) of the related Mortgaged Property conducted in
accordance with this Agreement within the preceding nine (9) month period or, in the absence of any such Appraisal, on a new
Appraisal. Except as provided in the following paragraph, the

 

     -237-

     

    

 

cost
of any Appraisal will be covered by, and will be reimbursable as, a Servicing Advance by the Master Servicer.

 

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

 

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

 

     -238-

     

    

 

or
the terms offered by the prospective buyer making the lower offer are more favorable); provided that the offeror is not
the Special Servicer or a Person that is an Affiliate of the Special Servicer. The Special Servicer shall use reasonable efforts
to sell all Defaulted Loans prior to the Rated Final Distribution Date. For the avoidance of doubt, the Trustee shall have no
obligation to make any fair value determination, to the extent required to do so pursuant to this Section 3.16, on the
basis of anything other than the related Appraisal.

 

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

 

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

 

(A)       In
the absence of any such offer as set forth in clause (i) above, the Special Servicer shall, subject to sub-clause (C)
below, accept the highest offer for such REO Property received from any Person that is determined to be a fair price (1) by the
Special Servicer, if the highest offeror is a Person other than an Interested Person, or (2) by the Trustee, if the highest offeror
is an Interested Person unless such offer by an Interested Person (i) is equal to or greater than the applicable Purchase Price
and (ii) is the highest offer received; provided, however, that absent an offer at least equal to the Purchase Price,
no offer from an Interested Person shall constitute a fair price unless (A) it is the highest offer received and (B) at least two
(2) other offers are received from independent third

 

     -239-

     

    

 

parties.
Notwithstanding anything to the contrary herein, neither the Trustee, in its individual capacity, nor any of its Affiliates may
make an offer for or purchase any REO Property pursuant hereto.

 

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

 

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

 

     -240-

     

    

 

REO
Property shall be without recourse to, or representation or warranty by, the Trustee, the Depositor, the Master Servicer, the
Special Servicer, the Certificate Administrator, the Operating Advisor or the Trust (except that any contract of sale and assignment
and conveyance documents may contain customary warranties of title, so long as the only recourse for breach thereof is to the
Trust) and, if consummated in accordance with the terms of this Agreement, none of the Master Servicer, the Special Servicer,
the Depositor, the Certificate Administrator, the Operating Advisor nor the Trustee shall have any liability to the Trust or any
Certificateholder or related Companion Holder (if applicable) with respect to the purchase price therefor accepted by the Special
Servicer or the Trustee.

 

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

 

(d)       With
respect to each Serviced Pari Passu Whole Loan, pursuant to the terms of the related Intercreditor Agreement and this Agreement,
if the related Serviced Pari Passu Whole Loan becomes a Defaulted Loan, and if the Special Servicer determines to sell the related
Mortgage Loan that has become a Defaulted Loan in accordance with this Section 3.16, then the Special Servicer shall sell
the related Serviced Pari Passu Companion Loan together with such Mortgage Loan as one whole loan and shall require that all offers
be submitted to the Special Servicer in writing. To the extent a determination is required to be made hereunder as to whether any
cash offer constitutes a fair price for a Serviced Whole Loan, such determination shall be made by the Trustee if the offeror is
an Interested Person. Notwithstanding the foregoing, the Special Servicer will not be permitted to sell the related Mortgage Loan
together with the related Serviced Pari Passu Companion Loan(s) if it becomes a defaulted Whole Loan without the written consent
of the holder of the related Serviced Pari Passu Companion Loan (provided that such consent is not required if the holder
of the Serviced Pari Passu Companion Loan is the Mortgagor or an Affiliate of the Mortgagor) unless the Special Servicer has delivered
to the holder of the related Serviced Pari Passu Companion Loan: (a) at least fifteen (15) Business Days prior written notice of
any decision to attempt to sell such Serviced Whole Loan; (b) at least ten (10) days prior to the permitted sale date, a copy of
each bid package (together with any amendments to such bid packages) received by the Special Servicer in connection with any such
proposed sale; (c) at least ten (10) days prior to the proposed sale date, a copy of the most recent appraisal for such Serviced
Pari Passu Whole Loan, and any documents in the servicing file reasonably requested by the holder of the related Serviced Pari
Passu Companion Loan; and (d) until the sale is completed, and a reasonable period of time (but no less time than is afforded to
other offerors and the Directing Certificateholder and the Risk Retention Consultation Party) prior to the proposed sale date,
all information and other documents being provided to other offerors and all leases or other documents that are approved by the
Master 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

 

     -241-

     

    

 

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
loans similar to the subject Mortgage Loan, that has been selected with reasonable care by the Trustee to determine if such cash
offer constitutes a fair price for such Mortgage Loan. The Trustee shall act in a commercially reasonable manner in making such
determination. If the Trustee designates such a third party to make such determination, the Trustee shall be entitled to rely
conclusively upon such third party’s determination. The reasonable fees of, and the costs of all appraisals, inspection
reports and broker opinions of value incurred by any such third party shall be covered by, and shall be reimbursable, from the
offering Interested Person and the Special Servicer shall use efforts consistent with the Servicing Standard to collect payment
from such Interested Person. If such expense is not paid by the applicable Interested Person within thirty (30) days of demand
for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing Advance but the Special Servicer
shall continue to use efforts consistent with the Servicing Standard to collect such amounts from the applicable Interested Person.

 

(e)       (i)
Notwithstanding anything in this Section 3.16 to the contrary, pursuant to the terms of the related Intercreditor Agreement,
the holder of the related AB Subordinate Companion Loan for each applicable Serviced AB Whole Loan will have the right to purchase
the related Mortgage Loan or related REO Property, as applicable. Such right of the holder of the AB Subordinate Companion Loan
shall be given priority over any provision described in this Section 3.16 as and to the extent set forth in the related
Intercreditor Agreement. If the related Mortgage Loan or related REO Property is purchased by the holder of such AB Subordinate
Companion Loan, repurchased by the applicable Mortgage Loan Seller or otherwise ceases to be subject to this Agreement, the related
AB Subordinate Companion Loan will no longer be subject to this Agreement.

 

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

 

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

 

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

 

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

 

     -242-

     

    

 

(b)       The
Master Servicer or the Special Servicer, as applicable, shall provide to each Companion Holder any reports or notices required
to be delivered to such Companion Holder pursuant to the related Intercreditor Agreement.

 

(c)       Upon
the determination that a previously made Advance is a Nonrecoverable Advance, to the extent that the reimbursement thereof would
exceed the full amount of the principal portion of general collections on the Mortgage Loans deposited in the Collection Account
and available for distribution on the next Distribution Date, the Master Servicer or the Trustee, each at its own option and in
its sole discretion, as applicable, instead of obtaining reimbursement for the remaining amount of such Nonrecoverable Advance
pursuant to Section 3.05(a)(v) immediately, as an accommodation may elect to refrain from obtaining such reimbursement for
such portion of the Nonrecoverable Advance during the one month collection period ending on the then-current Determination Date,
for successive one month periods for a total period not to exceed twelve (12) months (provided that, other than in the case
of an Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, any
such deferral exceeding six (6) months shall require, prior to the occurrence and continuance of any Control Termination Event,
the consent of the Directing Certificateholder), and any election to so defer or not to defer shall be deemed to be in accordance
with the Servicing Standard. If the Master Servicer or the Trustee makes such an election at its sole option and in its sole discretion
to defer reimbursement with respect to all or a portion of a Nonrecoverable Advance (together with interest thereon), then such
Nonrecoverable Advance (together with interest thereon) or portion thereof shall continue to be fully reimbursable in the subsequent
collection period (subject, again, to the same sole option to defer; it is acknowledged that, in such a subsequent period, such
Nonrecoverable Advance shall again be payable first from principal collections as described above prior to payment from
other collections). In connection with a potential election by the Master Servicer or the Trustee to refrain from the reimbursement
of a particular Nonrecoverable Advance or portion thereof during the Collection Period for any Distribution Date, the Master Servicer
or the Trustee shall further be authorized to wait for principal collections on the Mortgage Loans to be received until the end
of such Collection Period before making its determination of whether to refrain from the reimbursement of a particular Nonrecoverable
Advance or portion thereof; provided, however, that if, at any time the Master Servicer or the Trustee, as applicable,
elects, in its sole discretion, not to refrain from obtaining such reimbursement or otherwise determines that the reimbursement
of a Nonrecoverable Advance during a Collection Period will exceed the full amount of the principal portion of general collections
on or in respect of Mortgage Loans deposited in the Collection Account for such Distribution Date, then the Master Servicer or
the Trustee, as applicable, shall use its reasonable efforts to give the 17g-5 Information Provider fifteen (15) days’ notice
of such determination for posting on the 17g-5 Information Provider’s Website pursuant to Section 3.13(c), unless
extraordinary circumstances make such notice impractical, which shall mean that (i) the Master Servicer or the Trustee, as the
case may be, determines in its sole discretion that waiting fifteen (15) days after such a notice could jeopardize its ability
to recover such Nonrecoverable Advance, (ii) changed circumstances or new or different information becomes known to the Master
Servicer or the Trustee, as the case may be, that could affect or cause a determination of whether any Advance is a Nonrecoverable
Advance or whether to defer reimbursement of a Nonrecoverable Advance or the determination in clause (i) above, or (iii)
in the case of the Master Servicer, it has not timely received from the Trustee information required by the Master Servicer to
determine whether to defer

 

     -243-

     

    

 

reimbursement
for a Nonrecoverable Advance. If any of the circumstances described in clause (i), (ii) or (iii) of the foregoing
sentence apply, the Master Servicer or Trustee, as applicable, shall give the 17g-5 Information Provider a notice for posting
of the anticipated reimbursement as soon as reasonably practicable. Notwithstanding the foregoing, failure to give notice as required
by the preceding or second preceding sentence shall in no way affect the Master Servicer’s or the Trustee’s election
whether to refrain from obtaining such reimbursement or right to obtain such reimbursement as described in this Section 3.17(c).
Nothing herein shall give the Master Servicer or the Trustee the right to defer reimbursement of a Nonrecoverable Advance to the
extent of any principal collections then available in the Collection Account pursuant to Section 3.05(a)(v). The Master
Servicer or the Trustee, as the case may be, shall have no liability for any loss, liability or expenses resulting from any notice
provided to the Rating Agencies contemplated by this Section 3.17(c).

 

The foregoing shall not,
however, be construed to limit any liability that may otherwise be imposed on such Person for any failure by such Person to comply
with the conditions to making such an election under this Section 3.17 or to comply with the terms of this Section 3.17
and the other provisions of this Agreement that apply once such an election, if any, has been made; provided, however,
that the fact that a decision to recover such Nonrecoverable Advances over time, or not to do so, benefits some classes of Certificateholders
to the detriment of other classes shall not, with respect to the Master Servicer or the Special Servicer, as applicable, constitute
a violation of the Servicing Standard and/or with respect to the Trustee (solely in its capacity as Trustee), constitute a violation
of any fiduciary duty to Certificateholders or any contractual obligation hereunder. If the Master Servicer or the Trustee, as
the case may be, determines, in its sole discretion, to fully recover the Nonrecoverable Advances immediately instead of deferring
such reimbursement, then the Master Servicer or the Trustee, as applicable, shall be entitled to immediate reimbursement of Nonrecoverable
Advances with interest thereon at the Reimbursement Rate from all amounts in the Collection Account for such Distribution Date
(deemed first from principal and then from interest). Any such election by any such party to refrain from reimbursing
itself or obtaining reimbursement for any Nonrecoverable Advance or portion thereof with respect to any one or more collection
periods shall not limit the accrual of interest at the Reimbursement Rate on such Nonrecoverable Advance for the period prior to
the actual reimbursement of such Nonrecoverable Advance. The Master Servicer’s or the Trustee’s, as the case may be,
agreement to defer reimbursement of such Nonrecoverable Advances as set forth above is an accommodation to the Certificateholders
and shall not be construed as an obligation on the part of the Master Servicer or the Trustee, as applicable, or a right of the
Certificateholders. Nothing herein shall be deemed to create in the Certificateholders a right to prior payment of distributions
over the Master Servicer’s or the Trustee’s, as applicable, right to reimbursement for Advances (deferred or otherwise)
and accrued interest thereon. In all events, the decision to defer reimbursement or to seek immediate reimbursement of Nonrecoverable
Advances shall be deemed to be in accordance with the Servicing Standard and none of the Master Servicer, the Trustee or the other
parties to this Agreement shall have any liability to one another or to any of the Certificateholders or any of the Companion Holders
for any such election that such party makes as contemplated by this Section 3.17 or for any losses, damages or other adverse
economic or other effects that may arise from such an election, nor shall such election constitute a violation of the Servicing
Standard or any duty under this Agreement. Neither the Master Servicer nor the Trustee shall have any

 

     -244-

     

    

 

liability
whatsoever for making an election, or refraining from making an election, that is authorized under this Section 3.17(c).

 

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

 

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

 

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

 

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

 

Section 3.18     Modifications,
Waivers, Amendments and Consents. (a) The Special Servicer shall process waivers,
modifications, amendments and consents with respect to Specially Serviced Loans and all such matters that involve a Major Decision
or Special Servicer Decision for all Mortgage Loans (and any related Serviced Companion Loan) that are not Specially Serviced
Loans, and the Master Servicer shall process waivers, modifications, amendments and consents with respect to any Mortgage Loan
(other than any Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that is not a Specially Serviced Loan and
does not involve a Major Decision or a Special Servicer Decision. Except as set forth in Section 3.08(a), Section 3.08(b),
this Section 3.18(a), Section 3.18(d), Section 3.18(h), Section 3.18(i), Section 3.18(m) and
Section 6.08, but subject to any other conditions set forth thereunder and, with respect to any Mortgage Loan (other than
any Non-Serviced Mortgage Loan) or any Serviced Whole Loan (and with respect to any Serviced Whole Loan, subject to the rights
of the related Companion Holder, as applicable, to advise or consult with the Special Servicer with respect to, or to consent
to, a modification, waiver or amendment, in each case, pursuant to the terms of the related Intercreditor Agreement), the Special
Servicer shall not

 

     -245-

     

    

 

modify,
waive or amend the terms of a Mortgage Loan and/or related Companion Loan that would constitute a Major Decision without (x) (i)
prior to the occurrence of a Control Termination Event and (ii) other than with respect to any Excluded Loan with respect to the
Directing Certificateholder, the consent (or deemed consent) of the Directing Certificateholder having been obtained by the Special
Servicer to the extent required by, and pursuant to the process described under, Section 6.08(a) or (y) (i) after the occurrence
and during the continuance of a Control Termination Event and (ii) other than with respect to any Excluded Loan with respect to
the Directing Certificateholder, but prior to the occurrence and continuance of a Consultation Termination Event, the Special
Servicer having consulted with the Directing Certificateholder if and to the extent required pursuant to Section 6.08(a);
and provided, further, that no extension entered into pursuant to this Section 3.18(a) shall extend the Maturity
Date beyond the earlier of (i) five (5) years prior to the Rated Final Distribution Date and (ii) in the case of a Mortgage Loan
secured solely or primarily by a leasehold estate and not also the related fee interest, the date twenty (20) years or, to the
extent consistent with the Servicing Standard giving due consideration to the remaining term of the Ground Lease, ten (10) years,
prior to the expiration of such leasehold estate. If such extension would extend the Maturity Date of such Mortgage Loan and/or
related Companion Loan for more than twelve (12) months from and after the original Maturity Date of such Mortgage Loan and/or
related Companion Loan and such Mortgage Loan and/or related Companion Loan is not in default or default with respect thereto
is not reasonably foreseeable, prior to any such extension, (1) the Special Servicer shall provide the Trustee, the Certificate
Administrator, the Master Servicer, the Operating Advisor, the Directing Certificateholder and the Risk Retention Consultation
Party (in the case of the Directing Certificateholder and the Risk Retention Consultation Party, (i) prior to the occurrence and
continuance of a Consultation Termination Event and (ii) other than with respect to any Mortgage Loan that is an Excluded Loan
as to such party), with an Opinion of Counsel (at the expense of the related Mortgagor to the extent permitted under the Mortgage
Loan documents and, if not required or permitted to be paid by the Mortgagor, to be paid as an expense of the Trust in accordance
with Section 3.11(d)) that such extension would not constitute a “significant modification” of the Mortgage Loan and/or
Serviced Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b) and (2) subject to the Servicing Standard,
(x) prior to the occurrence and continuance of a Control Termination Event and other than with respect to any Excluded Loan with
respect to the Directing Certificateholder, the Special Servicer shall obtain the consent (or deemed consent) of the Directing
Certificateholder, (y) after the occurrence and during the continuance of a Control Termination Event, but prior to the occurrence
and continuance of a Consultation Termination Event, and other than with respect to any Excluded Loan with respect to the Directing
Certificateholder, consult with the Directing Certificateholder and (z) (i) prior to the occurrence and continuance of a Consultation
Termination Event, with respect to any Specially Serviced Loan other than an Excluded Loan with respect to the Risk Retention
Consultation Party and (ii) after the occurrence and during the continuance of a Consultation Termination Event, with respect
to any Mortgage Loan other than an Excluded Loan with respect to the Risk Retention Consultation Party, consult with the Risk
Retention Consultation Party, in each case, pursuant to the process described in Section 6.08(a).

 

Additionally, the Special
Servicer shall not modify, waive or amend the terms of any Mortgage Loan and/or related Companion Loan that would constitute a
Special Servicer Decision under any of clauses (d), (e), (f) and (g) of the definition of “Special Servicer
Decision” unless (x) (i) prior to the occurrence of a Control Termination Event and (ii) other than with

 

     -246-

     

    

 

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

 

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

 

Subject to Section
6.08, applicable law and the Mortgage Loan and/or related Serviced Companion Loan documents, neither the Master Servicer nor
the Special Servicer shall permit the substitution of any Mortgaged Property (or any portion thereof) for one or more other parcels
of real property at any time the Mortgage Loan and/or related Serviced Companion Loan is not in default pursuant to the terms of
the related Mortgage Loan and/or related Serviced Companion Loan documents or default with respect thereto is not reasonably foreseeable
unless (i) the Master Servicer or the Special Servicer, as the case may be, obtains Rating Agency Confirmation from each Rating
Agency (and delivers such Rating Agency Confirmation to the Directing Certificateholder and the Risk Retention Consultation Party,
if permitted by the applicable Rating Agency) and a confirmation of any applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if
any) (provided that such rating agency

 

     -247-

     

    

 

confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25)) and (ii) such substitution would not be a “significant modification”
of the Mortgage Loan and/or related Serviced Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b) or
otherwise cause an Adverse REMIC Event (and the Master Servicer or the Special Servicer, as the case may be, may obtain and rely
upon an Opinion of Counsel (at the expense of the related Mortgagor if not prohibited by the terms of the related Mortgage Loan
documents, and if so prohibited, at the expense of the Trust) with respect thereto).

 

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

 

(b)       If
the Special Servicer determines that a modification, waiver or amendment (including, without limitation, the forgiveness or deferral
of interest or principal or the substitution of collateral pursuant to the terms of the Mortgage Loan (other than any Non-Serviced
Mortgage Loan) and/or related Serviced Companion Loan or otherwise, the release of collateral or the pledge of additional collateral)
of the terms of a Specially Serviced Loan with respect to which a payment default or other material default has occurred or a payment
default or other material default is, in the Special Servicer’s judgment, reasonably foreseeable (as evidenced by an Officer’s
Certificate of the Special Servicer), is reasonably likely to produce a greater (or equivalent) recovery on a net present value
basis (the relevant discounting to be performed at the related Mortgage Rate) to the Trust and, if applicable, the Companion Holders,
as the holders of the related Serviced Companion Loan, than liquidation of such Specially Serviced Loan, then the Special Servicer
may agree to a modification, waiver or amendment of such Specially Serviced Loan, subject to (w) the provisions of this Section
3.18(b) and Section 3.18(c), (x) with respect to any such Specially Serviced Loan other than an Excluded Loan with respect
to the Directing Certificateholder, prior to the occurrence and continuance of a Control Termination Event, the approval of the
Directing Certificateholder (or after the occurrence and during the continuance of a Control Termination Event, but prior to the
occurrence and continuance of a Consultation Termination Event, upon consultation with the Directing Certificateholder) as provided
in Section 6.08, (y) with respect to any such Specially Serviced Loan other than an Excluded Loan with respect to the Risk
Retention Consultation Party, upon consultation with the Risk Retention Consultation Party as provided in Section 6.08,
and (z) additionally, with respect to a Serviced Whole Loan, the rights of the related Serviced Companion Noteholder or with respect
to a Mortgage Loan (other than any Non-Serviced Mortgage Loan) with mezzanine debt, the rights of the related mezzanine lender,
to advise or

 

     -248-

     

    

 

consult
with the Special Servicer with respect to, or consent to, such modification, waiver or amendment, in each case, pursuant to the
terms of the related Intercreditor Agreement or mezzanine intercreditor agreement, as applicable; provided that with respect
to any Serviced AB Whole Loan, prior to the occurrence and continuance of a related AB Control Appraisal Period, the related Serviced
AB Whole Loan Controlling Holder will be required to the extent set forth in the related Intercreditor Agreement and the Directing
Certificateholder shall have no consent or consultation rights, and the Risk Retention Consultation Party shall have no consultation
rights, regarding the matter; provided, further, that in the case of any release or substitution of collateral (other
than a defeasance), the Special Servicer shall have obtained an Opinion of Counsel that such release or substitution would not
be a “significant modification” of the Mortgage Loan within the meaning of Treasury Regulations Section 1.860G-2(b)
or otherwise cause an Adverse REMIC Event. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan
with respect to the Directing Certificateholder (regardless of whether a Control Termination Event has occurred and is continuing),
the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in connection with the related transactions
involving proposed Major Decisions and consider alternative actions recommended by the Operating Advisor, in respect thereof,
in accordance with the procedures set forth in Section 6.08 for consulting with the Operating Advisor.

 

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

 

If, following any such
release or taking, the loan-to-value ratio as calculated is greater than 125%, the Master Servicer or the Special Servicer, as
the case may be, shall require payment of principal by a “qualified amount” as determined under Revenue Procedure 2010-30
or successor provisions, unless the related Mortgagor provides an Opinion of Counsel that if such amount is not paid, the related
Mortgage Loan will not fail to be a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code.

 

The Special Servicer
shall use its reasonable efforts to the extent possible to cause each Specially Serviced Loan to fully amortize prior to the Rated
Final Distribution Date and shall not agree to a modification, waiver or amendment of any term of any Specially Serviced Loan if
such modification, waiver or amendment would (1) extend the maturity date of any such Specially Serviced Loan to a date occurring
later than the earlier of (a) five (5) years prior to the Rated Final Distribution Date and (b) if such Specially Serviced Loan
is secured solely or primarily by a leasehold estate and not also the related fee interest, the date occurring twenty (20) years
or, to the extent consistent with the Servicing Standard giving due consideration to the

 

     -249-

     

    

 

remaining
term of the ground lease and (A) prior to the occurrence and continuance of a Control Termination Event, with the consent of the
Directing Certificateholder and (B) to the extent such modification, waiver or amendment constitutes a Major Decision, after consultation
with the Risk Retention Consultation Party pursuant to Section 6.08(a), (in each case, other than with respect to a Mortgage
Loan that is an Excluded Loan as to such party), ten (10) years prior to the expiration of such leasehold estate (including any
options to extend such leasehold estate exercisable unilaterally by the related Mortgagor), or (2) provide for the deferral of
interest unless interest accrues on the related Mortgage Loan, or Serviced Whole Loan generally at the related Mortgage Rate.

 

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

 

(d)       To
the extent consistent with this Agreement (including, without limitation, the first sentence of Section 3.18(a), and Section
6.08), the Master Servicer (as provided in Section 3.08(a), Section 3.08(b) and Section 3.18 if such matter
constitutes a Master Servicer Decision) or the Special Servicer (as provided in Section 3.08(a), Section 3.08(b)
and Section 3.18(a) if any such waiver, modification or amendment constitutes a Major Decision or a Special Servicer Decision
or relates to a Specially Serviced Loan) may, consistent with the Servicing Standard, agree to any waiver, modification or amendment
of a Mortgage Loan and/or Serviced Companion Loan that is not in default or as to which default is not reasonably foreseeable only
if the contemplated waiver, modification or amendment (i) will not be a “significant modification” of the Mortgage
Loan within the meaning of Treasury Regulations Section 1.860G-2(b) and (ii) will not cause an Adverse REMIC Event. In making this
determination, the Master Servicer or the Special Servicer may obtain and rely upon (and shall provide to the Trustee and the Certificate
Administrator if obtained) an Opinion of Counsel (at the expense of the related Mortgagor or such other Person requesting such
modification or, if such expense cannot be collected from the related Mortgagor or such other Person, to be paid out of the Collection
Account pursuant to Section 3.05(a); provided that the Master Servicer or the Special Servicer, as the case may be,
shall use its reasonable efforts to collect such fee from the Mortgagor or such other Person to the extent permitted under the
related Mortgage Loan documents). Notwithstanding the foregoing, neither the Master Servicer nor the Special Servicer may waive
the payment of any Prepayment Premium or Yield Maintenance Charge or the requirement that any prepayment of a Mortgage Loan be
made on a Due Date, or if not made on a Due Date, be accompanied by all interest that would be due on the next Due Date with respect
to any Mortgage Loan or Serviced Companion Loan that is not a Specially Serviced Loan.

 

(e)       Subject
to Section 3.18(c), the Master Servicer and the Special Servicer each may, as a condition to its granting any request by
a Mortgagor for consent, modification (including extensions), waiver or indulgence or any other matter or thing, the granting of
which

 

     -250-

     

    

 

is
within the Master Servicer’s or the Special Servicer’s, as the case may be, discretion pursuant to the terms of the
instruments evidencing or securing the related Mortgage Loan or Companion Loan and is permitted by the terms of this Agreement,
require that such Mortgagor pay to the Master Servicer or the Special Servicer, as the case may be, as additional servicing compensation,
a reasonable or customary fee, for the additional services performed in connection with such request; provided that the
charging of such fee is not a “significant modification” of the Mortgage Loan within the meaning of Treasury Regulations
Section 1.860G-2(b).

 

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

 

(g)       With
respect to any modification, waiver or amendment for which it is responsible for processing pursuant to Section 3.18, the
Special Servicer shall notify the Master Servicer, the Trustee, the Certificate Administrator, the Operating Advisor (after the
occurrence and during the continuance of a Control Termination Event), the Directing Certificateholder and the Risk Retention Consultation
Party (in the case of the Directing Certificateholder, other than following the occurrence and continuance of a Consultation Termination
Event, and in the case of the Directing Certificateholder or the Risk Retention Consultation Party, other than with respect to
any Excluded Loan as to such party), the applicable Companion Holder (unless, with respect to a holder of an AB Subordinate Companion
Loan, an AB Control Appraisal Period has occurred, if applicable), the related Mortgage Loan Seller (if such Mortgage Loan Seller
is not the Master Servicer or Sub-Servicer of such Mortgage Loan or the Directing Certificateholder or the Risk Retention Consultation
Party) and the 17g-5 Information Provider (which shall promptly post such notice on the 17g-5 Information Provider’s Website
in accordance with Section 3.13(c)) in writing of any modification, waiver or amendment (in each case, after it is finalized
and executed) of any term of any Mortgage Loan or Companion Loan that is modified, waived or amended and the date thereof. With
respect to any modification, waiver or amendment (in each case, after it is finalized and executed) for which it is responsible
for processing pursuant to Section 3.18, the Master Servicer shall provide written notice of any such modification, waiver
or amendment to the Trustee, the Certificate Administrator, the Special Servicer (and the Special Servicer shall forward such notice
to the Directing Certificateholder and the Risk Retention Consultation Party (in the case of the Directing Certificateholder, only
prior to the occurrence and continuance of a Consultation Termination Event and in the case of the Directing Certificateholder
or the Risk Retention Consultation Party, other than with respect to an Excluded Loan as to such party), the applicable Companion
Holder (unless, with respect to a holder of an AB Subordinate Companion Loan, an AB Control Appraisal Period has occurred, if applicable)

Loan or the Directing Certificateholder or Risk Retention Consultation Party) and the 17g-5 Information Provider (which shall promptly
post such notice on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)). The party responsible

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)

 

     -251-

     

    

 

following
the execution thereof, with a copy to the applicable Companion Holder, if any. Following receipt of the Master Servicer’s
or the Special Servicer’s, as the case may be, delivery of the aforesaid modification, waiver or amendment to the Certificate
Administrator, the Certificate Administrator shall forward a copy thereof to each Holder of a Certificate (other than the Class
R or Class V Certificates). With respect to any modification, waiver or consent that is a Master Servicer Decision pursuant to
clause (iv) of the definition of “Master Servicer Decision”, if the related lease affects an area greater than
or equal to 10% of net rentable area of the related Mortgaged Property and less 30% of net rentable area of the related Mortgaged
Property, the Master Servicer shall deliver to the Special Servicer a copy of the approved lease. With respect to any modification,
waiver or consent that is a Master Servicer Decision pursuant to (vii) of the definition of “Master Servicer Decision”,
the Master Servicer shall deliver to the Special Servicer a copy of the approved annual budget. 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 Master Servicer processes such modification, waiver or consent pursuant to Sections 3.18(a) and (m) 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

debt or mezzanine debt, deliver notice of the Mortgagor’s incurrence of such debt, substantially in the form of Exhibit
JJ, to cts.sec.notifications@wellsfargo.com and an Additional Disclosure
Notification in the form attached hereto as Exhibit DD. The notice contemplated in the preceding sentence shall set forth,
to the extent the Special Servicer or the Master Servicer, as the case may be, has the requisite information or can reasonably
obtain such information, (1) the amount of additional debt that was incurred in the related Collection Period, (2) the total debt
service coverage ratio calculated on the basis of such Mortgage Loan and additional debt, and (3) the aggregate LTV Ratio calculated
on the basis of such Mortgage Loan and additional debt. In the event that either (i) the CREFC® Investor Reporting
Package is amended to include such information set forth above, in a manner reasonably acceptable to the Master Servicer, the
Special Servicer and the Certificate Administrator, as applicable, and the Master Servicer confirms with the Certificate Administrator
that such amended CREFC® Investor Reporting Package enables the Certificate Administrator to include such information
on Form 10-D in a manner reasonably acceptable to the Certificate Administrator, or (ii) the Trust is no longer subject to the
Exchange Act, the additional report in the form of Exhibit JJ shall no longer be required hereunder. From time to time,
the Master Servicer, the Special Servicer and the Certificate Administrator may agree on a different delivery time and format
for the information set forth in this paragraph.

 

(h)       Subject
to the consent rights and processes set forth in Section 6.08 with respect to Major Decisions, the Master Servicer shall
process all defeasance transactions and shall be entitled to all defeasance fees paid related thereto (provided that for
the avoidance of doubt, any such defeasance fee shall not include any Modification Fees or waiver fees in connection with a defeasance
that the Special Servicer is entitled to under this Agreement). Notwithstanding the foregoing, the Master Servicer shall not permit
(or, with regard to any Non-Serviced Mortgage Loan, take any act in furtherance of) the substitution of any Mortgaged Property
pursuant to the defeasance provisions of any Mortgage Loan or a Serviced Whole Loan unless such defeasance complies with Treasury
Regulations Section 1.860G-2(a)(8)(ii) and the Master Servicer has received (i) replacement collateral consisting of government
securities

 

     -252-

     

    

 

within
the meaning of Treasury Regulations Section 1.860G-2(a)(8)(ii), which satisfies the requirements of the applicable Mortgage Loan
documents, in an amount sufficient to make all scheduled payments under the related Mortgage Loan (or defeased portion thereof)
when due, (ii) a certificate of an Independent certified public accountant to the effect that such substituted property will provide
cash flows sufficient to meet all payments of interest and principal (including payments at maturity) on such Mortgage Loan or
Serviced Whole Loan in compliance with the requirements of the terms of the related Mortgage Loan documents and, if applicable,
Companion Loan documents, (iii) one or more Opinions of Counsel (at the expense of the related Mortgagor) to the effect that the
Trustee, on behalf of the Trust, will have a first priority perfected security interest in such substituted Mortgaged Property;
provided, however, that, to the extent consistent with the related Mortgage Loan documents and, if applicable, Companion
Loan documents, the related Mortgagor shall pay the cost of any such opinion as a condition to granting such defeasance, (iv)
to the extent consistent with the related Mortgage Loan documents and, if applicable, Companion Loan documents, the Mortgagor
shall establish a single purpose entity to act as a successor mortgagor, if so required by the Rating Agencies, (v) to the extent
permissible under the related Mortgage Loan documents and, if applicable, Companion Loan documents, the Master Servicer shall
use its reasonable efforts to require the related Mortgagor to pay all costs of such defeasance, including but not limited to
the cost of maintaining any successor mortgagor, and (vi) to the extent permissible under the Mortgage Loan documents and, if
applicable, Companion Loan documents, the Master Servicer shall obtain, at the expense of the related Mortgagor, Rating Agency
Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will not result in
the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if
any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency
Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25); provided, further,
however, that no such confirmation from any Rating Agency shall be required to the extent that the Master Servicer has
delivered a defeasance certificate substantially in the form of Exhibit U hereto for any Mortgage Loan that (together with
any Mortgage Loans cross-collateralized with such Mortgage Loans) is: (i) a Mortgage Loan with a Cut-off Date Balance less than
$20,000,000, (ii) a Mortgage Loan that represents less than 5% of the aggregate Cut-off Date Balance of all Mortgage Loans a,
and (iii) a Mortgage Loan that is not one of the ten (10) largest Mortgage Loans by Stated Principal Balance. Notwithstanding
the foregoing, in the event that requiring the Mortgagor to pay for the items specified in clauses (ii), (iv) and
(v) in the preceding sentence would be inconsistent with the related Mortgage Loan documents, such reasonable costs shall
be paid by the related Mortgage Loan Seller as and to the extent set forth in the applicable Mortgage Loan Purchase Agreement.

 

(i)       Notwithstanding
anything herein or in the related Mortgage Loan documents and, if applicable, Companion Loan documents, to the contrary, the Master
Servicer may permit the substitution of “government securities,” within the meaning of Section 2(a)(16) of the Investment
Company Act of 1940, that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii) for any Mortgaged Property pursuant to the
defeasance provisions of any Mortgage Loan or a Serviced Whole Loan, as applicable (or any portion thereof), in lieu of the defeasance
collateral specified in the related Mortgage Loan documents or Serviced Whole Loan documents, as applicable; provided that
such substitution is consistent with the Servicing Standard and the Master Servicer reasonably determines that allowing their use
would not cause

 

     -253-

     

    

 

a
default or event of default to become reasonably foreseeable and the Master Servicer receives an Opinion of Counsel (at the expense
of the Mortgagor to the extent permitted under the Mortgage Loan documents and, if applicable or Companion Loan documents or otherwise
as a Trust Fund expense) to the effect that such use would not be and would not constitute a “significant modification”
of such Mortgage Loan or Companion Loan pursuant to Treasury Regulations Section 1.860G-2(b) and would not otherwise constitute
an Adverse REMIC Event with respect to any Trust REMIC; and provided, further, that the requirements set forth in
Section 3.18(h) (including receipt of any Rating Agency Confirmation) are satisfied; and provided, further,
that such securities are backed by the full faith and credit of the United States government, or the Master Servicer shall obtain
Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will
not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities
(if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency
Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25).

 

Notwithstanding the foregoing,
with respect to (i) all of the Mortgage Loans (other than The Summit Birmingham Mortgage Loan), originated or acquired by Bank
of America, National Association that are subject to defeasance and (ii) all of the Mortgage Loans originated or acquired by Morgan
Stanley Mortgage Capital Holdings LLC that are subject to defeasance, each of Bank of America, National Association and Morgan
Stanley Mortgage Capital Holdings LLC, as applicable, has transferred to a third party or has retained on behalf of itself or an
Affiliate the right to establish or designate the successor borrower and/or to purchase or cause to be purchased the related defeasance
collateral (any such right or obligation, the “Retained Defeasance Rights and Obligations”). In the event the
Master Servicer receives notice of a defeasance request with respect to a Mortgage Loan for which Bank of America, National Association
or Morgan Stanley Mortgage Capital Holdings LLC, as applicable, is the related Mortgage Loan Seller, which such Mortgage Loan provides
for Retained Defeasance Rights and Obligations in the related Mortgage Loan documents, the Master Servicer shall provide, within
five (5) Business Days of receipt of such notice, written notice of such defeasance request to Bank of America, National Association
or Morgan Stanley Mortgage Capital Holdings LLC, as applicable, in the case of any such Mortgage Loan for which Bank of America,
National Association or Morgan Stanley Mortgage Capital Holdings LLC, as applicable, is the related Mortgage Loan Seller. Until
such time as Bank of America, National Association or Morgan Stanley Mortgage Capital Holdings LLC, as applicable, provides the
Master Servicer with written notice to the contrary, the notice of a defeasance of a Mortgage Loan with Retained Defeasance Rights
and Obligations as to which (i) Bank of America, National Association is the related Mortgage Loan Seller shall be delivered to

Morgan
Stanley Mortgage Capital Holdings LLC, 1221 Avenue of the Americas, New York, New York 10020, Attention: Legal Compliance Division).
With respect to any Mortgage Loan originated or acquired by Bank of America, National Association or Morgan Stanley Mortgage Capital
Holdings LLC, as applicable, that is subject to defeasance, if the successor borrower is not designated or formed by Bank of America,
National Association or Morgan Stanley Mortgage Capital Holdings LLC, as the case may be, or any Affiliate or successor thereto,
the successor borrower shall be reasonably acceptable to the Master Servicer in accordance with the Servicing Standard.

 

(j)     
  If required under the related Mortgage Loan or Companion Loan documents or if otherwise consistent with the
Servicing Standard, the Master Servicer shall establish and maintain one or more accounts (the “Defeasance
Accounts”), which shall be Eligible Accounts, into which all payments received by the Master Servicer from any
defeasance collateral substituted for any Mortgaged Property shall be deposited and retained, and shall administer such
Defeasance Accounts in accordance with the Mortgage Loan or Companion Loan documents. Notwithstanding the foregoing, in no
event shall the Master Servicer permit such amounts to be maintained in the Defeasance Account for a period in excess of
ninety (90) days, unless such amounts are reinvested by the Master Servicer in “government securities,” within
the meaning of Section 2(a)(16) of the Investment Company Act of 1940, that comply with Treasury Regulations Section
1.860G-2(a)(8)(ii). To the extent not required or permitted to be placed in a separate account, the Master Servicer shall
deposit all payments received by it from defeasance collateral substituted for any Mortgaged Property into the Collection
Account and treat any such payments as payments made on the Mortgage Loan or Companion Loan in advance of its Due Date in
accordance with clause (a)(i) of the definition of “Aggregate 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 three hundred sixty-five
(365) days (or three hundred sixty-six (366) days in the case of a leap year).

 

(k)       Notwithstanding
anything to the contrary in this Agreement, neither the Master Servicer nor the Special Servicer, as the case may be, shall, unless
it has received Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such
action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion
Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as
any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25) (the
cost of which shall be paid by the related Mortgagor, if so allowed by the terms of the related loan documents and otherwise paid
out of general collections) grant or accept any consent, approval or direction regarding the termination of the related property
manager or the designation of any replacement property manager, with respect to any Mortgaged Property that secures a Mortgage
Loan that (i) is one of the ten (10) largest Mortgage Loans a by Stated Principal Balance or (ii) has an unpaid principal balance
that is at least equal to 5% of the then-aggregate principal balance of all Mortgage Loans or $35,000,000.

 

(l)        Notwithstanding
anything to the contrary in this Agreement, in connection with any modification, waiver, consent or amendment in connection with
any release of collateral securing any Mortgage Loan in connection with a defeasance of such collateral, the

 

     -255-

     

    

 

Special
Servicer shall not approve any such modification, waiver or amendment or consent thereto without first having received a copy
of an Opinion of Counsel addressed to the Special Servicer and the Master Servicer that such modification, waiver, consent or
amendment will not cause an Adverse REMIC Event.

 

(m)       Notwithstanding
any other provisions of this Section 3.18 or Section 3.08, but subject to any related Intercreditor Agreement, the
Master Servicer may, without any Directing Certificateholder approval, consent or consultation (except as otherwise provided below
in the definition of Master Servicer Decision), Risk Retention Consultation Party consultation or the Special Servicer’s
approval, consent or consultation (provided that the Master Servicer delivers notice thereof to the Special Servicer after
completion (and the Special Servicer shall promptly, prior to the occurrence of a Consultation Termination Event and other than
in respect of any Excluded Loan with respect to the Directing Certificateholder, deliver notice thereof to the Directing Certificateholder,
except to the extent that the Special Servicer notifies the Master Servicer that the Special Servicer does not desire to receive
copies of such items) take any of the following actions with respect to Non-Specially Serviced Loans (each such action, a “Master
Servicer Decision”): (i) grant waivers of non-material covenant defaults (other than financial covenants and receipt
of financial statements, but including immaterial timing waivers such as with respect to late financial statements); (ii) consents
to releases of non-material, non-income producing parcels of a Mortgaged Property that do not materially affect the use or value
of the related Mortgaged Property or the ability of the related Mortgagor to pay amounts due in respect of the Mortgage Loan as
and when due, provided such releases are required by the related Mortgage Loan documents and there is no lender discretion permitted
under the Mortgage Loan documents; (iii) approve or consent to grants of easements or rights of way (including, without limitation
for utilities, access, parking, public improvements or another purpose) or subordination of the lien of the Mortgage Loan to easements
if the Special Servicer has determined, in accordance with the proviso to the definition of “Special Servicer Decision”,
that such easements or rights of way do not materially affect the use or value of a Mortgaged Property or a Mortgagor’s ability
to make payments with respect to the related Mortgage Loan or any related Companion Loan; (iv) grant subordination, non-disturbance
and attornment agreements and consents involving leasing activities that do not involve a ground lease and affect an area less
than or equal to the lesser of (a) 30% of the net rentable area of the improvements at the Mortgaged Property and (b) 30,000 square
feet of the improvements at the Mortgaged Property), including approval of new leases and amendments to current leases; (v) consent
to actions and releases related to condemnation of parcels of a Mortgaged Property if the Special Servicer has determined, in accordance
with the proviso to the definition of “Special Servicer Decision”, that such condemnation is not with respect to a
material parcel or a material income producing parcel and such condemnation does not materially affect the use or value of the
related Mortgaged Property or the ability of the related Mortgagor to pay amounts due in respect of the related Mortgage Loan or
Companion Loan when due; (vi) consent to a change in property management relating to any Mortgage Loan if the replacement property
manager is not a Borrower Party and the Mortgage Loan has an outstanding principal balance less than $10,000,000; (vii) approve
annual operating budgets for Mortgage Loans; (viii) grant any extension or enter into any forbearance with respect to the anticipated
refinancing of a Mortgage Loan or sale of a Mortgaged Property after the related Maturity Date of such Mortgage Loan so long as

sale of the related Mortgaged Property will occur within 120 days after the date on which such Balloon Payment will become due;
(ix) any non-material modification, amendment, consent to a non-material modification or waiver of any term of any Intercreditor
Agreement if the Special Servicer has determined, in accordance with the proviso to the definition of “Major Decision”
that such modification, amendment or consent is administrative in nature, including a note-splitting amendment, provided
that if any such modification or amendment would adversely impact the Special Servicer, such modification or amendment will additionally
require the consent of the Special Servicer, as applicable, as a condition to its effectiveness; (x) any determination of Acceptable
Insurance Default, except that, prior to the occurrence and continuance of any Control Termination Event and other than in the
case of any Excluded Loan with respect to the Directing Certificateholder, the Directing Certificateholder’s consent (or
deemed consent) shall be required for any such determination; (xi) approve or consent to any defeasance of the related Mortgage
Loan or Serviced Companion Loan other than agreeing to (A) a modification of the type of defeasance collateral required under
the Mortgage Loan or Serviced Whole Loan documents other than direct, non-callable obligations of the United States would be permitted
or (B) a modification that would permit a principal prepayment instead of defeasance if the Mortgage Loan or Serviced Whole loan
documents do not otherwise permit such principal prepayment; (xii) any determination to bring a Mortgaged Property into compliance
with applicable environmental laws or to otherwise address hazardous material located at a Mortgaged Property subject, prior to
the occurrence and continuance of a Control Termination Event and other than with respect to any Excluded Loan with respect to
the Directing Certificateholder, to the consent (or deemed consent) of the Directing Certificateholder; (xiii) any transfer of
the Mortgaged Property that the loan documents allow without the consent of the mortgagee but subject to satisfaction of conditions
specified in the loan documents where no mortgagee discretion is necessary in order to determine if such conditions are satisfied;
(xiv) to the extent not a Major Decision or a Special Servicer Decision pursuant to clause (x) of the definition of “Major
Decision” or clause (c) of the definition of “Special Servicer Decision”, respectively, any requests
for the funding or disbursement of amounts from any escrow accounts, reserve funds or letters of credit held as “performance”,
“earn-out”, “holdback” or similar escrows or reserves where such request is for funding or disbursement
of ordinary course impounds, repair and replacement reserves, lender approved budget and operating expenses, and tenant improvements
pursuant to an approved lease, each in accordance with the Mortgage Loan documents (all such fundings and disbursements being
collectively referred to as “Routine Disbursements”) or any other funding or disbursement as mutually agreed
upon by the Master Servicer and the Special Servicer; provided, however, that in the case of any Mortgage Loan whose
escrows, reserves, holdbacks and related letters of credit exceed, in the aggregate, at the related origination date, 10% of the
initial principal balance of such Mortgage Loan (which Mortgage Loans are identified on Schedule 3 hereto), no such funding
or disbursement of such escrows, reserves, holdbacks or letters of credit shall be deemed to constitute a Routine Disbursement,
and shall instead constitute Special Servicer Decisions, except for the routine funding of tax payments and insurance premiums
when due and payable; and (xv) grant or agree to any other waiver, modification, amendment and/or consent that does not constitute
a Major Decision or a Special Servicer Decision; provided that (w) any such action would not in any way affect a payment
term of the Certificates, (x) any such action would not constitute a “significant modification” of such Mortgage Loan
or Companion Loan pursuant to

 

     -257-

     

    

 

Treasury
Regulations Section 1.860G-2(b) and would not otherwise cause either Trust REMIC to fail to qualify as a REMIC for federal income
tax purposes (as evidenced by an Opinion of Counsel (at the expense of the Trust to the extent not reimbursed or paid by the related
Mortgagor), to the extent requesting such opinion is consistent with the Servicing Standard), (y) agreeing to such action would
be consistent with the Servicing Standard, and (z) agreeing to such action would not violate the terms, provisions or limitations
of this Agreement or any Intercreditor Agreement; provided, further, that, in the case of any Master Servicer Decision
that requires the consent of the Directing Certificateholder, such consent shall be deemed given if a response to the request
for consent is not provided within 10 Business Days after receipt of the Master Servicer’s written recommendation and analysis
and all information reasonably requested by the Directing Certificateholder, and reasonably available to the Master Servicer in
order to grant or withhold such consent. The foregoing is intended to be an itemization of actions the Master Servicer may take
without having to obtain the approval of any other party and is not intended to limit the responsibilities of the Master Servicer
hereunder.

 

(n)       No
Master Servicer or Special Servicer shall modify any Mortgage Loan into an AB Modified Loan unless the documents evidencing such
modification provide that all payments on the junior or “B” portion of such AB Modified Loan (including interest, principal
and other amounts) shall only be payable after the point in time at which all interest and principal on the senior or “A”
portion of such AB Modified Loan shall have been paid in full and such senior or “A” portion shall no longer be outstanding;
provided, however, that interest and other amounts in respect of such junior or “B” portion may accrue prior to such
point in time.

 

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

 

     -258-

     

    

 

Master
Servicer shall deliver to the Trustee, the Certificate Administrator, the Operating Advisor, the Directing Certificateholder (with
respect to the Directing Certificateholder (i) prior to the occurrence and continuance of a Consultation Termination Event and
(ii) other than with respect to any Excluded Loan as to such party), a copy of the notice of such Servicing Transfer Event provided
by the Master Servicer to the Special Servicer, or by the Special Servicer to the Master Servicer, pursuant to this Section
3.19. Prior to the occurrence and continuance of a Consultation Termination Event, the Certificate Administrator shall deliver
to each Controlling Class Certificateholder a copy of the notice of such Servicing Transfer Event provided by the Master Servicer
pursuant to this Section 3.19.

 

Upon determining that
a Specially Serviced Loan (other than an REO Loan) has become current and has remained current for three (3) consecutive Periodic
Payments (provided that (i) no additional Servicing Transfer Event is foreseeable in the reasonable judgment of the Special
Servicer, and (ii) for such purposes taking into account any modification or amendment of such Mortgage Loan and, if applicable,
the related Companion Loan), and that no other Servicing Transfer Event is continuing with respect thereto, the Special Servicer
shall immediately give notice thereof to the Master Servicer, the Operating Advisor, the related Serviced Companion Noteholder
(unless with respect to an AB Subordinate Companion Loan an AB Control Appraisal Period has occurred) and the Directing Certificateholder
(with respect to the Directing Certificateholder, (i) prior to the occurrence and continuance of a Consultation Termination Event
and (ii) other than with respect to any Excluded Loan as to such party) and shall return the related Mortgage File and Servicing
File to the Master Servicer (or copies thereof if copies only were delivered to the Special Servicer) and upon giving such notice,
and returning such Mortgage File and Servicing File to the Master Servicer, the Special Servicer’s obligation to service
such Corrected Loan shall terminate and the obligations of the Master Servicer to service and administer such Mortgage Loan and,
if applicable, the related Companion Loan shall recommence.

 

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

 

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

 

(d)       No
later than sixty (60) days after a Servicing Transfer Event for a Mortgage Loan (other than a Non-Serviced Mortgage Loan) and,
if applicable, the related Companion Loan, the Special Servicer shall deliver in electronic format a report (the “Asset
Status Report”) with respect to such Mortgage Loan and related Companion Loan, if applicable,

 

     -259-

     

    

 

and
the related Mortgaged Property to the Master Servicer, the Directing Certificateholder (but with respect to the Directing Certificateholder,
only in respect of any Mortgage Loan other than (A) any Excluded Loan as to such party or (B) any Serviced AB Whole Loan prior
to the occurrence of an AB Control Appraisal Period, and in any event prior to the occurrence and continuance of a Consultation
Termination Event), the Risk Retention Consultation Party (but only with respect to any Mortgage Loan other than an Excluded Loan
as to such party), the Operating Advisor (but, other than with respect to an Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class, only after the occurrence and during the continuance of a Control Termination
Event) and the 17g-5 Information Provider (which shall promptly post such report on the 17g-5 Information Provider’s Website
in accordance with Section 3.13(c)) and, with respect to any related Serviced Companion Loan, to the related Companion
Holder or, to the extent the related Serviced Companion Loan has been included in an Other Securitization, to the applicable master
servicer of such Other Securitization into which the related Serviced Companion Loan has been sold; the Special Servicer shall
also deliver a summary of each Final Asset Status Report to the Certificate Administrator and the Certificate Administrator shall
post the summary of the Final Asset Status Report to the Certificate Administrator’s Website. Such Asset Status Report shall
set forth the following information to the extent reasonably determinable based on the information that was delivered to the Special
Servicer in connection with the transfer of servicing pursuant to the Servicing Transfer Event:

 

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

 

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

 

(iii)     the
most current rent roll, and income or operating statement available for the related Mortgaged Property;

 

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

 

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

 

     -260-

     

    

 

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

 

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

 

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

 

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

 

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

 

If
within ten (10) Business Days of receiving an Asset Status Report, the Directing Certificateholder does not disapprove such Asset
Status Report in writing or if the Special Servicer makes a determination, in accordance with the Servicing Standard that the
disapproval by the Directing Certificateholder (communicated to the Special Servicer within ten (10) Business Days) is not in
the best interest of all the Certificateholders and the holder of any related Companion Loan, as a collective whole (taking into
account the pari passu or subordinate nature of any Companion Loan), the Special Servicer shall implement the recommended
action as outlined in such Asset Status Report; provided, however, that the Special Servicer may not take any action
that is contrary to applicable law, the Servicing Standard or the terms of the applicable Mortgage Loan documents. If, with respect
to any Mortgage Loan other than an Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority
of the Controlling Class, prior to the occurrence and continuance of any Control Termination Event, the Directing Certificateholder
disapproves such Asset Status Report within ten (10) Business Days of receipt and the Special Servicer has not made the affirmative
determination described above, the Special Servicer shall revise such Asset Status Report and deliver a new Asset Status Report
as soon as practicable, but in no event later than thirty (30) days after such disapproval, to the Master Servicer, the Directing
Certificateholder (prior to the occurrence and continuance of a Consultation Termination Event and, in the case of a Serviced
AB Whole Loan, only prior to the occurrence and continuance of a Consultation Termination Event and during an AB Control Appraisal
Period with respect to the related AB Subordinate Companion Loan), the Operating Advisor (but only after the occurrence and during
the continuance of a Control Termination Event) and the 17g-5 Information Provider (which shall promptly post such report on the
17g-5 Information Provider’s Website in accordance with Section 3.13(c)). With respect to any Mortgage Loan other
than an Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class,
prior to the occurrence and continuance of any Control Termination Event, the Special Servicer shall revise such Asset Status
Report as

 

     -261-

     

    

 

described above in this Section 3.19(d) until the Directing Certificateholder shall fail to disapprove such revised
Asset Status Report in writing within ten (10) Business Days of receiving such revised Asset Status Report or until the Special
Servicer makes a determination, in accordance with the Servicing Standard, that the disapproval is not in the best interests of
the Certificateholders and the holder of any related Companion Loan, as a collective whole (taking into account the pari passu
or subordinate nature of any Companion Loan); provided that, if the Directing Certificateholder has not approved the
Asset Status Report for a period of sixty (60) Business Days following the first submission of an Asset Status Report, the Special
Servicer may act upon the most recently submitted form of Asset Status Report, if consistent with the Servicing Standard; provided,
however, that such Asset Status Report does not, and is not intended to be, a substitute for the approvals that are specifically
required pursuant to Section 6.08. The Special Servicer may, from time to time, modify any Asset Status Report it has previously
delivered and implement such report; provided that such report shall have been prepared, reviewed and not rejected pursuant
to the terms of this Section 3.19(d). Notwithstanding anything herein to the contrary, with respect to any Excluded Loan
with respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class (regardless of whether
a Control Termination Event has occurred and is continuing), the Special Servicer shall consult with the Operating Advisor, on
a non-binding basis, in connection with an Asset Status Report for an Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class that includes a Major Decision and consider alternative actions recommended
by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting
with the Operating Advisor.

 

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

 

If
a Control Termination Event has occurred and is continuing (or, with respect to a Serviced AB Whole Loan, if both a Control Termination
Event has occurred and is continuing and an AB Control Appraisal Period is in effect), the Special Servicer shall promptly deliver
each Asset Status Report prepared in connection with a Specially Serviced Loan to the Operating Advisor (and the Directing Certificateholder
(if no Consultation Termination Event has occurred and is continuing and such Specially Serviced Loan is not an Excluded Loan
as to such party)). The Operating Advisor shall provide comments to the Special Servicer in respect of the Asset Status Report,
if any, within ten (10) Business Days following the later of (i) receipt of such Asset Status Report or (ii) receipt of such additional
information reasonably requested by the Operating Advisor related thereto, and propose possible alternative courses of action
to the

 

     -262-

     

    

 

extent it determines such alternatives to be in the best interest of the Certificateholders (including any Certificateholders
that are holders of the Control Eligible Certificates), as a collective whole. The Special Servicer shall consider such alternative
courses of action and any other feedback provided by the Operating Advisor (and the Directing Certificateholder (in each case,
if no Consultation Termination Event has occurred and is continuing and such Specially Serviced Loan is not an Excluded Loan as
to such party or a Non-Serviced Mortgage Loan)) in connection with the Special Servicer’s preparation of any Asset Status
Report. The Special Servicer may revise the Asset Status Report as it deems necessary to take into account any input and/or comments
from the Operating Advisor (and the Directing Certificateholder (if no Consultation Termination Event has occurred and is continuing
and such Specially Serviced Loan is not an Excluded Loan as to such party)), to the extent the Special Servicer determines that
the Operating Advisor’s and/or Directing Certificateholder’s input and/or recommendations are consistent with the
Servicing Standard and in the best interest of the Certificateholders as a collective whole (or, with respect to a Serviced Whole
Loan, the best interest of the Certificateholders and the holders of the related Companion Loan, as a collective whole (taking
into account the pari passu or subordinate nature of such Companion Loan)).

 

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

 

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

(e)            (i)Upon
receiving notice of the occurrence of the events described in clause (iv) or (ix) of the definition of Servicing
Transfer Event (without regard to the 60-day or 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
relating to the Mortgage Loan or Serviced Companion Loan and reasonably requested by the Special Servicer to enable it to negotiate
with the related Mortgagor. The Master Servicer shall use its reasonable efforts to comply with the preceding sentence within
five (5) Business Days of the occurrence of each such event.

 

(ii)            After
the occurrence and during the continuance of a Control Termination Event, upon receiving notice of the occurrence of an event
described in clause (iv) or (ix) of the definition of Servicing Transfer Event (without regard to the 60-day or
30-day period, respectively, set forth therein), the Master Servicer shall deliver notice thereof to the Operating Advisor at
the same time such notice is provided to the Special Servicer pursuant to clause (i) above.

 

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

 

     -264-

     

    

 

such disapproval. The Special Servicer shall promptly deliver (but in any event no later than two (2) Business Days following
its completion) a copy of each Final Asset Status Report to the Operating Advisor. The Special Servicer shall prepare a summary
of any Final Asset Status Report related to any Serviced AB Whole Loan for which the related holder of an AB Subordinate Companion
Loan is not subject to an AB Control Appraisal Period, which Final Asset Status Report has been approved or deemed approved by
the holder of the related AB Subordinate Companion Loan in accordance with the related Intercreditor Agreement (to the extent
such Intercreditor Agreement requires such approval or deemed approval), and deliver in electronic format notice of such Final
Asset Status Report and the summary of such Final Asset Status Report to the Certificate Administrator for posting on the Certificate
Administrator’s Website pursuant to Section 3.13(b).

 

(g)            No
provision of this Section 3.19 shall require the Special Servicer to take or to refrain from taking any action because
of any proposal, objection or comment by the Operating Advisor or a recommendation of the Operating Advisor.

 

Section
3.20     Sub-Servicing Agreements. (a) The Master Servicer and the Special Servicer may enter
into Sub-Servicing Agreements to provide for the performance by third parties of any or all of its respective obligations
hereunder; provided that the Sub-Servicing Agreement as amended or modified: (i) is consistent with this Agreement in
all material respects and requires the Sub-Servicer to comply with all of the applicable conditions of this Agreement; (ii)
provides that if the Master Servicer or the Special Servicer, as the case may be, shall for any reason no longer act in such
capacity hereunder (including, without limitation, by reason of a Servicer Termination Event), the Trustee or its designee
shall thereupon assume all of the rights and, except to the extent they arose prior to the date of assumption, obligations of
such party under such agreement, or, alternatively, may act in accordance with Section 7.02 under the circumstances
described therein (subject to Section 3.20(g)); (iii) provides that the Trustee (for the benefit of the
Certificateholders and the related Companion Holder (if applicable)) and the Trustee (as holder of the Lower-Tier Regular
Interests) shall be a third party beneficiary under such Sub-Servicing Agreement, but that (except to the extent the Trustee
or its designee assumes the obligations of such party thereunder as contemplated by the immediately preceding clause
(ii)) none of the Trust, the Trustee, the Operating Advisor, the Certificate Administrator, the Master Servicer or
Special Servicer, as applicable, (other than the Master Servicer or Special Servicer that enters into such Sub-Servicing
Agreement) any successor master servicer or successor special servicer or any Certificateholder (or the related Companion
Holder, if applicable) shall have any duties under such Sub-Servicing Agreement or any liabilities arising therefrom; (iv)
permits any purchaser of a Mortgage Loan pursuant to this Agreement to terminate such Sub-Servicing Agreement with respect to
such purchased Mortgage Loan at its option and without penalty; provided, however, that the Initial

in such additional manner and by such other Persons as is provided in such Sub-Servicing Agreement; (v) does not permit the
Sub-Servicer any direct rights of indemnification that may be satisfied out of assets of the Trust except through the Master
Servicer or the Special Servicer, as the case may be, if and only to the extent provided pursuant to Section 6.04;
(vi) does not permit the Sub-Servicer to modify any Mortgage Loan unless and to the extent the Master Servicer or the Special

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

 

     -266-

     

    

 

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

 

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

 

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

 

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

 

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

 

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

 

     -267-

     

    

 

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

 

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

 

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

 

Section
3.21     Interest Reserve Account.

 

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

 

(b)            On
each P&I Advance Date occurring in March (or February, if the related Distribution Date is the final Distribution Date), the
Certificate Administrator shall withdraw,

 

     -268-

     

    

 

from the Interest Reserve Account an amount equal to the Withheld Amounts from the preceding
January (if applicable) and February, if any, and deposit such amount into the Lower-Tier REMIC Distribution Account.

 

Section
3.22     Directing Certificateholder and Operating Advisor Contact with the Master Servicer and the
Special Servicer. Within a reasonable time upon request from the Directing Certificateholder or the Operating Advisor, as
applicable, and no more often than on a monthly basis, each of the Master Servicer and the Special Servicer shall, without charge,
make a knowledgeable Servicing Officer via telephone available to verbally answer questions from (a) the Directing Certificateholder
((i) prior to the occurrence and continuance of a Consultation Termination Event and (ii) other than with respect to any Excluded
Loan as to such party) and (b) upon the occurrence and during the continuance of any Control Termination Event, the Operating
Advisor (with respect to the Special Servicer only), regarding the performance and servicing of the Mortgage Loans and/or REO
Properties for which the Master Servicer or the Special Servicer, as the case may be, is responsible.

 

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

 

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

 

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

 

(b)            Once
a Directing Certificateholder has been selected, each of the Master Servicer, the Special Servicer, the Depositor, the Trustee,
the Certificate Administrator, the Operating Advisor and each other Certificateholder (or Certificate Owner, if applicable) shall
be

 

     -269-

     

    

 

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

 

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

 

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

 

     -270-

     

    

 

 

(e)       
   Upon request, the Certificate Administrator shall deliver to the Depositor, Trustee, the Special Servicer,
the Operating Advisor, the Master Servicer and, prior to the occurrence and continuance of a Consultation Termination Event,
the Directing Certificateholder, a list of each Controlling Class Certificateholder as reflected in the Certificate Register,
including names and addresses. In addition to the foregoing, within five (5) Business Days of receiving notice of the
selection of a new Directing Certificateholder or Risk Retention Consultation Party or the existence of a new Controlling
Class Certificateholder, the Certificate Administrator shall notify the Trustee, the Operating Advisor, the Master Servicer
and the Special Servicer. Notwithstanding the foregoing, (a) RREF III Debt AIV, LP, shall be the initial Directing
Certificateholder and shall remain so until a successor is appointed pursuant to the terms of this Agreement or until a
Consultation Termination Event occurs and is continuing, and (b) Wells Fargo Bank, National Association shall be the initial
Risk Retention Consultation Party and shall remain so until a successor is appointed pursuant to the terms of this Agreement
or until a Consultation Termination Event occurs and is continuing.

 

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

 

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

 

(g)            Each
Certificateholder acknowledges and agrees, by its acceptance of its Certificates, that: (i) the Directing Certificateholder may
have special relationships and interests that conflict with those of Holders of one or more Classes of Certificates; (ii) the
Directing Certificateholder may act solely in the interests of the Holders of the Controlling Class or in its own interest; (iii)
the Directing Certificateholder does not have any liability or duties to the Holders of any Class of Certificates other than the
Controlling Class; (iv) the Directing Certificateholder may take actions that favor interests of the Holders of one or more Classes
including the Controlling Class over the interests of the Holders of one or more other Classes of Certificates; and (v) the Directing
Certificateholder shall have no liability whatsoever (other than to a Controlling Class Certificateholder) for having so acted
as set forth in clauses (i) through (v) above, and no Certificateholder may take any action whatsoever against the
Directing Certificateholder or any director, officer, employee, agent or principal of the Directing Certificateholder for having
so acted.

 

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

 

     -271-

     

    

 

Risk Retention Consultation
Party shall have no liability whatsoever (other than to a Holder of an RR Interest) for having so acted as set forth in clauses
(i) through (iv) above, and no Certificateholder may take any action whatsoever against the Risk Retention Consultation
Party or any director, officer, employee, agent or principal of the Risk Retention Consultation Party for having so acted.

 

(h)            (i)
All requirements of the Master Servicer and the Special Servicer to provide notices, reports, statements or other information
(including the access to information on a website) to the Directing Certificateholder contained in this Agreement shall also apply
to each Companion Holder with respect to information relating to the related Serviced AB Mortgage Loan or a Serviced Whole Loan,
as applicable; provided, however, that nothing in this subsection (h) shall in any way eliminate the obligation
to deliver any information required to be delivered under the related Intercreditor Agreement.

 

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

 

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

 

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

 

(l)             At
any time that the Controlling Class Certificateholder is the Holder of a majority of the Class F Certificates and the Class F
Certificates are the Controlling Class may waive its right (a) to appoint the Directing Certificateholder and (b) to exercise
any of the Directing Certificateholder’s rights under this Agreement by irrevocable written notice delivered to the Depositor,
the Certificate Administrator (which shall be via email to trustadministrationgroup@wellsfargo.com), the Master Servicer, the
Special Servicer and the Operating Advisor. Notwithstanding anything to the contrary contained herein, during such time as a Control
Termination Event or Consultation Termination Event is in existence solely as a result of the operation of clause (ii)
of the definition of Control Termination Event and clause (ii) of the definition of Consultation Termination Event, such
Control Termination Event or Consultation Termination Event shall be deemed to no longer be in existence and have not occurred
with respect to any unaffiliated third party to whom the Controlling Class Certificateholder that irrevocably waived its right
to exercise any of the rights of the Controlling Class Certificateholder has sold or transferred all or a portion of its interest
in the Class F Certificates if such unaffiliated third party holds the majority of the Controlling Class after giving effect to
such transfer (the “Non-Waiving Successor”). Following any such sale or transfer, the Non-Waiving Successor
shall again have the rights of the Controlling Class

 

     -272-

     

    

 

Certificateholder as set forth herein (including the rights to appoint a
Directing Certificateholder or cause the exercise of the rights of the Directing Certificateholder) without regard to any prior
waiver by the predecessor Controlling Class Certificateholder. The Non-Waiving Successor shall also have the right to irrevocably
waive its right to appoint the Directing Certificateholder and to exercise any of the rights of the Controlling Class Certificateholder.
The Non-Waiving Successor shall also have the right to exercise any of the rights of the Controlling Class Certificateholder.
No Non-Waiving Successor described above shall have any consent rights with respect to any Mortgage Loan that became a Specially
Serviced Loan prior to the sale or transfer of the Class F Certificates to the Non-Waiving Successor and had not also become a
Corrected Loan prior to such sale or transfer until such time as such Mortgage Loan becomes a Corrected Loan.

 

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

 

In
the event that a Control Termination Event has occurred pursuant to clause (i) of the definition thereof, such special notice
shall state “A Control Termination Event has occurred due to the reduction of the Certificate Balance of the Class F Certificates
to less than 25% of the aggregate Original Certificate Balance thereof, with regard to the application of any Cumulative Appraisal
Reduction Amounts.”

 

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

 

In
the event that a Control Termination Event or Consultation Termination Event has occurred pursuant to clause (ii) of the definition
of each of such terms, such special notice shall state “A Control Termination Event and a Consultation Termination Event
has occurred due to the irrevocable waiver by the applicable Controlling Class Certificateholder of its rights as Controlling
Class Certificateholder.”

 

In
the event that a Consultation Termination Event has occurred due to the reduction of each Class of Control Eligible Certificates
below 25% of its Original Certificate Balance, in each case without regard to the application of any Cumulative Appraisal Reduction
Amounts, such special notice shall state: “A Consultation Termination Event has occurred

 

     -273-

     

    

 

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

 

The
Directing Certificateholder shall not have any consent or consultation rights with respect to any Mortgage Loan determined to
be an Excluded Loan as to either the Directing Certificateholder or the Holder of the majority of the Controlling Class. Likewise,
the Risk Retention Consultation Party shall not have any consultation rights with respect to any Mortgage Loan determined to be
an Excluded Loan as to either such Risk Retention Consultation Party or the Holder of the majority of the RR Interest. Notwithstanding
the proviso to each of the definitions of “Control Termination Event” and “Consultation Termination Event”,
in either such case, in respect of the servicing of any such Excluded Loan, a Control Termination Event and Consultation Termination
Event will be deemed to have occurred with respect to such Excluded Loan.

 

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

 

(b)            Neither
the Master Servicer nor the Special Servicer shall have any liability for any cost, claim or damage that arises from any entitlement
in favor of a Companion

 

     -274-

     

    

 

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 the case may be, be required to consult with or obtain the consent of a new Directing
Certificateholder or a new Controlling Class Certificateholder or consult with a new Risk Retention Consultation Party unless
the Certificate Administrator has delivered notice to the Master Servicer or the Special Servicer, as applicable, as required
under Section 3.23(e) or the Master Servicer or the Special Servicer, as applicable, have actual knowledge of the identity
and contact information of a new Directing Certificateholder, a new Controlling Class Certificateholder or a new Risk Retention
Consultation Party.

 

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

 

(d)            With
respect to any Serviced Pari Passu Companion Loan, notwithstanding any rights the Operating Advisor, the Directing Certificateholder
or the Risk Retention Consultation Party hereunder may have to consult with respect to any action or other matter with respect
to the servicing of such Companion Loan, to the extent the related Intercreditor Agreement provides that such right is exercisable
by the related Companion Holder or is exercisable in conjunction with any related Companion Holder, the Directing Certificateholder
and the Risk Retention Consultation Party shall not be permitted to exercise such right or, to the extent provided in the related
Intercreditor Agreement, shall be required to exercise such right in conjunction with the related Companion Holder, as applicable
(except to the extent that the Directing Certificateholder or the Risk Retention Consultation Party is the related Serviced Whole
Loan Controlling Holder). Additionally, notwithstanding anything in this Agreement to the contrary, the Master Servicer or the
Special Servicer, as the case may be, shall consult, seek the approval or obtain the consent of the holder of any Serviced Companion
Loan with respect to any matters with respect to the servicing of such Companion Loan to the

 

     -275-

     

    

 

extent required under related Intercreditor
Agreement and shall not take such actions requiring consent of the related Companion Holder without such consent. In addition,
notwithstanding anything to the contrary, the Master Servicer or the Special Servicer, as the case may be, shall deliver reports
and notices to the related Companion Holder as required under the Intercreditor Agreement.

 

(e)            Notwithstanding
anything in this Agreement to the contrary, the Special Servicer shall be required (1) to provide copies of any notice, information
and report that it is required to provide to the Controlling Class Certificateholder pursuant to this Agreement with respect to
any Major Decisions or the implementation of any recommended actions outlined in an Asset Status Report relating to a Serviced
Whole Loan to the related Companion Holder, within the same time frame it is required to provide to the Controlling Class Certificateholder
(for this purpose, without regard to whether such items are actually required to be provided to the Controlling Class Certificateholder
under this Agreement due to the occurrence and continuance of a Control Termination Event or the occurrence and continuance of
a Consultation Termination Event) and (2) to consult with any related Companion Holder on a strictly non-binding basis, to the
extent having received such notices, information and reports, such related Companion Holder requests consultation with respect
to any such Major Decisions or the implementation of any recommended actions outlined in an Asset Status Report relating to a
Serviced Whole Loan, and consider alternative actions recommended by such related Companion Holder; provided that after
the expiration of a period of ten (10) Business Days from the delivery to such related Companion Holder by the Special Servicer
of written notice of a proposed action, together with copies of the notice, information and report required to be provided to
the Controlling Class Certificateholder, the Special Servicer shall no longer be obligated to consult with such related Companion
Holder, whether or not such related Companion Holder has responded within such ten (10) Business Day period (unless, the Special
Servicer proposes a new course of action that is materially different from the action previously proposed, in which case such
ten (10) Business Day period shall be deemed to begin anew from the date of such proposal and delivery of all information relating
thereto). Notwithstanding the consultation rights of the related Companion Holder set forth in the immediately preceding sentence,
the Special Servicer may make any Major Decision or take any action set forth in the Asset Status Report before the expiration
of the aforementioned ten (10) Business Day period if the Special Servicer determines that immediate action with respect thereto
is necessary to protect the interests of the Certificateholders and the related Companion Holder. In no event shall the Special
Servicer be obligated at any time to follow or take any alternative actions recommended by the related Companion Holder.

 

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

 

(g)            With
respect to any Serviced Whole Loan, the Special Servicer shall not modify, waive or amend the terms of the related Intercreditor
Agreement such that the monthly

 

     -276-

     

    

 

remittance to the holder of the related Companion Loan is required earlier than 2 Business Days
after receipt by the Master Servicer of the related Periodic Payment without the consent of the Master Servicer.

 

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

 

Section
3.25     Rating Agency Confirmation. (a) Notwithstanding the terms of any related Mortgage
Loan documents or other provisions of this Agreement, if any action under any Mortgage Loan documents or this Agreement
requires Rating Agency Confirmation as a condition precedent to such action, if the party (the “RAC Requesting
Party”) required to obtain such Rating Agency Confirmation from each Rating Agency has made a request to any Rating
Agency for such Rating Agency Confirmation and, within ten (10) Business Days of the Rating Agency Confirmation request being
posted to the 17g-5 Information Provider’s Website, such Rating Agency has not replied to such request or has responded
in a manner that indicates that such Rating Agency is neither reviewing such request nor waiving the requirement for Rating
Agency Confirmation, then such RAC Requesting Party shall be required to confirm (through direct communication and not by
posting any confirmation on the 17g-5 Information Provider’s Website) that the applicable Rating Agency has received
the Rating Agency Confirmation request, and, if it has not, promptly request the related Rating Agency Confirmation again.
The circumstances described in the preceding sentence are referred to in this Agreement as a “RAC No-Response
Scenario.” Once the RAC Requesting Party has sent a request for a Rating Agency Confirmation to the 17g-5
Information Provider, such RAC Requesting Party may, but shall not be obligated to send such request directly to the Rating
Agencies in accordance with the procedures set forth in Section 13.10(d).

 

If
there is no response to such Rating Agency Confirmation request within five (5) Business Days of such second request in a RAC
No-Response Scenario or if such Rating Agency has responded in a manner that indicates such Rating Agency is neither reviewing
such request nor waiving the requirement for Rating Agency Confirmation, then (x) with respect to any condition in any Mortgage
Loan document requiring such Rating Agency Confirmation or with respect to any other matter under this Agreement relating to the
servicing of the Mortgage Loans (other than as set forth in clause (y) below), the requirement to obtain a Rating Agency
Confirmation shall be deemed not to apply (as if such requirement did not exist) with respect to such Rating Agency and the Master
Servicer or the Special Servicer, as the case may be, may then take such action if the Master Servicer or the Special Servicer,
as the case may be, confirms its original determination (made prior to making such request) that taking the action with respect
to which it requested the Rating Agency Confirmation would still be consistent with the Servicing Standard, and (y) with respect
to a replacement of the Master Servicer or the Special Servicer, such condition shall be deemed not to apply (as if such requirement
did not exist) if (i) the applicable replacement master servicer or special servicer has been appointed and currently serves as
a master servicer or special servicer, as applicable, on a transaction-level basis on a CMBS transaction currently rated by Moody’s
that currently has securities outstanding and for which Moody’s has not cited servicing concerns with respect to such replacement
master servicer or special servicer as the sole or 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 any other CMBS
transaction serviced by such replacement master servicer or special servicer prior to the time of determination, if Moody’s
is the non-responding Rating Agency, (ii) the applicable replacement master servicer or special servicer is rated at least “CMS3”
(in the case of the replacement master servicer) or “CSS3” (in the case of the replacement special servicer), if Fitch
is the non-responding Rating Agency or (iii) KBRA has not publicly cited servicing concerns with respect to the applicable replacement
master servicer or special servicer as the sole or a material factor in any qualification, downgrade or withdrawal of the ratings
(or placement on “watch status” in contemplation of a rating downgrade or withdrawal) of securities in any other CMBS
transaction serviced by such replacement master servicer or special servicer prior to the time of determination, if KBRA 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 or to make a determination with respect to such Rating Agency
Confirmation pursuant to Section 3.25(a) shall be deemed not to apply (as if such requirement did not exist).

 

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

 

Section
3.26  The Operating Advisor. (a) The Operating Advisor shall promptly review (i) all information made available to
Privileged Persons on the Certificate Administrator’s Website (A) that relates to any Specially Serviced Loan, and (B)
that is contained in the

 

     -278-

     

    

 

CREFC® Servicer Watch
List prepared by the Master Servicer and (ii) each Final Asset Status Report delivered to the Operating Advisor by the Special
Servicer.

 

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

 

(c)            (i)
After the occurrence and during the continuance of a Control Termination Event, based on the Operating Advisor’s review
of any assessment of compliance report, attestation report, Asset Status Report and other information (other than any
communications between the Directing Certificateholder and the Special Servicer that would be Privileged Information)
delivered to the Operating Advisor by the Special Servicer, including each Asset Status Report delivered during the prior
calendar year, the Operating Advisor shall (if any Mortgage Loans were Specially Serviced Loans during the prior calendar
year) deliver to the Certificate Administrator and the 17g-5 Information Provider within one hundred-twenty (120) days of the
end of the prior calendar year for which a Control Termination Event was continuing as of December 31, an annual report (the
“Operating Advisor Annual Report”), substantially in the form of Exhibit V (which form may be
modified or altered as to either its organization or content by the Operating Advisor, subject to compliance of such form
with the terms and provisions of this Agreement including, without limitation, provisions herein relating to Privileged
Information; provided, however, that in no event shall the information or any other content included in the
Operating Advisor Annual Report contravene any provision of this Agreement), setting forth the Operating Advisor’s
assessment of the Special Servicer’s performance of its duties under this Agreement during the prior calendar year on a
“platform-level basis” with respect to the resolution and/or liquidation of Specially Serviced Loans that the
Special Servicer is responsible for servicing under this Agreement; provided, further, however, that in
the event the Special Servicer is replaced, the Operating Advisor Annual Report shall only relate to the Special
Servicer that was acting as Special Servicer as of December 31 in the prior calendar year and is continuing in such capacity
through the date of such Operating Advisor Annual Report. Notwithstanding the foregoing, with respect to any Serviced AB
Whole Loan, no Operating Advisor Annual Report will be permitted to include an assessment of the Special Servicer’s
performance in respect of such Serviced AB Whole Loan until after the occurrence and during the continuance of an AB Control
Appraisal Period under the related Intercreditor Agreement. Subject to the restrictions in this Agreement, including, without
limitation, Section 3.26(c), each such Operating Advisor Annual Report shall (A) identify any material deviations (i)
from the Servicing Standard and (ii) from the Special Servicer’s obligations under this Agreement with respect to the
resolution or liquidation of Specially Serviced Loans or REO Properties that the Special Servicer is responsible for
servicing under this Agreement (other than with respect to any REO Property related to a Non-Serviced Mortgage Loan) and (B)
comply with all of the confidentiality requirements described in this

 

     -279-

     

    

 

Agreement regarding Privileged Information (subject to any permitted exceptions); provided that the Operating
Advisor shall not be required to report on any instances of non-compliance with, or deviations from, the Servicing Standard or
the Special Servicer’s obligations under this Agreement that the Operating Advisor determines, in its sole discretion exercised
in good faith, to be immaterial. Such Operating Advisor Annual Report shall be delivered to the Master Servicer, the Special Servicer,
the Certificate Administrator (which shall promptly post such Operating Advisor Annual Report on the Certificate Administrator’s
Website in accordance with Section 3.13(b)) and the 17g-5 Information Provider (which shall promptly post such Operating
Advisor Annual Report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)); provided,
however, that the Special Servicer shall be given an opportunity to review the Operating Advisor Annual Report at least
five (5) Business Days prior to its delivery to the Certificate Administrator and the 17g-5 Information Provider. The Operating
Advisor shall have no obligation to adopt any comments to the Operating Advisor Annual Report that are provided by the Special
Servicer. Only as used in this Section 3.26 in connection with the Operating Advisor Annual Report, the term “platform-level
basis” refers to the Special Servicer’s performance of its duties as they relate to the resolution and/or liquidation
of Specially Serviced Loans, taking into account the Special Servicer’s specific duties under this Agreement as well as
the extent to which those duties were performed in accordance with the Servicing Standard, with reasonable consideration by the
Operating Advisor of any assessment of compliance report, attestation report, Asset Status Report and other information delivered
to the Operating Advisor by the Special Servicer (other than any communications between the Directing Certificateholder and the
Special Servicer that would be Privileged Information) pursuant to this Agreement. Notwithstanding the foregoing, no Operating
Advisor Annual Report shall be required from the Operating Advisor with respect to any calendar year as to which no Asset Status
Report was prepared by the Special Servicer in connection with a Specially Serviced Loan or REO Property.

 

(ii)            In
the event the Operating Advisor’s ability to perform its obligations in respect of the Operating Advisor Annual Report is
limited or prohibited due to the failure of a party hereto to timely deliver information required to be delivered to the Operating
Advisor or because such information is inaccurate or incomplete, the Operating Advisor shall set forth such limitations or prohibitions
in the related Operating Advisor Annual Report, and the Operating Advisor shall not be subject to any liability arising from such
limitations or prohibitions. The Operating Advisor shall be entitled to conclusively rely on the accuracy and completeness of
any information it is provided without liability for any such reliance hereunder. In the event a lack of access to Privileged
Information limits or prohibits the Operating Advisor from performing its duties under this Agreement, the Operating Advisor shall
set forth any such limitations or prohibitions in the related Operating Advisor Annual Report, and the Operating Advisor shall
not be subject to any liability arising from its lack of access to Privileged Information.

 

(d)            Prior
to the occurrence and continuance of a Control Termination Event (or, with respect to a Serviced AB Whole Loan, prior to the occurrence
and continuance of both a Control Termination Event and a related AB Control Appraisal Period), the Special Servicer will forward
any Appraisal Reduction Amount and net present value calculations used in the Special Servicer’s determination of what course
of action to take in connection with the workout or liquidation of a Specially Serviced Loan to the Operating Advisor after such
calculations have

 

     -280-

     

    

 

been finalized. The Operating Advisor shall review such calculations but shall not opine on or take any affirmative
action with respect to such Appraisal Reduction Amount calculations and/or net present value calculations (except that if the
Operating Advisor discovers a mathematical error contained in such calculations, them the Operating Advisor shall notify the Special
Servicer of such error).

 

(e)            (i)
After the occurrence and during the continuance of a Control Termination Event, and with respect to any Serviced AB Whole
Loan, after the occurrence and during the continuance of both a Control Termination Event and an AB Control Appraisal Period,
after the calculation but prior to the utilization by the Special Servicer of any of the calculations related to (i)
Appraisal Reduction Amounts or (ii) net present value in accordance with Section 1.02(iv), the Special Servicer shall
forward such calculations, together with any supporting material or additional information necessary in support thereof
(including such additional information reasonably requested by the Operating Advisor to confirm the mathematical accuracy of
such calculations, but not including any Privileged Communications), to the Operating Advisor promptly, but in any event no
later than two (2) Business Days after preparing such calculations, and the Operating Advisor shall promptly, but no later
than three (3) Business Days after receipt of such calculations and any supporting or additional materials, recalculate and
verify the accuracy of the mathematical calculations and the corresponding application of the non-discretionary portion of
the applicable formulas required to be utilized in connection with any such calculation.

 

(ii)            In
connection with this Section 3.26(e), in the event the Operating Advisor does not agree with the mathematical calculations
of the Appraisal Reduction Amount (as calculated by the Special Servicer) or net present value or the application of the applicable
non-discretionary portions of the formula required to be utilized for such calculation, the Operating Advisor and the Special
Servicer shall consult with each other in order to resolve any inaccuracy in the mathematical calculations or the application
of the non-discretionary portions of the related formula in arriving at those mathematical calculations or any disagreement within
five (5) Business Days of delivery of such calculations. The Master Servicer shall cooperate with the Special Servicer and provide
any information reasonably requested by the Special Servicer necessary for the calculation of the Appraisal Reduction Amount that
is either in the Master Servicer’s possession or, solely with respect to Non-Specially Serviced Loans, reasonably obtainable
by the Master Servicer. In the event the Operating Advisor and the Special Servicer are not able to resolve such inaccuracies
or disagreement prior to the end of such five (5) Business Day period, the Operating Advisor shall promptly notify the Certificate
Administrator of such disagreement and the Certificate Administrator shall examine the calculations and supporting materials provided
by the Operating Advisor and the Special Servicer and determine which calculation is to apply and shall provide such parties prompt
written notice of its determination.

 

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

 

     -281-

     

    

 

Certificateholder
or the Holder of the majority of the Controlling Class) and a related AB Control Appraisal Period.

 

(f)            [RESERVED].

 

(g)            The
Operating Advisor and its Affiliates shall keep all information appropriately labeled as “Privileged Information”
confidential and shall not disclose such Privileged Information to any Person (including Certificateholders other than the Directing
Certificateholder), other than (1) to the extent expressly required by this Agreement to the other parties to this Agreement with
a notice indicating that such information is Privileged Information or (2) pursuant to a Privileged Information Exception. Each
party to this Agreement that receives Privileged Information from the Operating Advisor with a notice stating that such information
is Privileged Information shall not disclose such Privileged Information to any Person without the prior written consent of the
Special Servicer and, unless a Control Termination Event has occurred and is continuing, the Directing Certificateholder (with
respect to any Mortgage Loan other than a Non-Serviced Whole Loan and other than any Mortgage Loan that is an Excluded Loan with
respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class) other than pursuant to a Privileged
Information Exception. Notwithstanding the foregoing, the Operating Advisor shall be permitted to share Privileged Information
with its Affiliates and any subcontractors of the Operating Advisor that agree in writing to be bound by the same confidentiality
provisions applicable to the Operating Advisor.

 

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

 

(i)             As
compensation for its activities hereunder, the Operating Advisor shall be entitled to receive the Operating Advisor Fee on each
Remittance Date with respect to each Mortgage Loan (excluding each Non-Serviced Mortgage Loan and each Companion Loan) and each
REO Loan. As to each Mortgage Loan and each REO Loan, the Operating Advisor Fee shall accrue from time to time at the Operating
Advisor Fee Rate and shall be computed on the basis of the Stated Principal Balance of such Mortgage Loan or REO Loan, as the
case may be, and in the same manner as interest is calculated on the related Mortgage Loan or REO Loan, as the case may be, and,
in connection with any partial month interest payment, for the same period respecting which any related interest payment due on
the related Mortgage Loan or deemed to be due on such REO Loan is computed.

 

The
Operating Advisor shall be entitled to reimbursement of any Operating Advisor Expenses provided for pursuant to Section 6.04(a)
and/or 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

 

     -282-

     

    

 

from
funds on deposit in the Collection Account as provided in Section 3.05(a)(ii) of this Agreement, but, with respect to the
period when the outstanding Certificate Balances of the Control Eligible Certificates has not been reduced to zero as a result
of the allocation of Realized Losses to such Certificates, only to the extent such Operating Advisor Consulting Fee is actually
received from the related Mortgagor. When the Operating Advisor has consultation obligations with respect to a Major Decision
under this Agreement, the Master Servicer or the Special Servicer, as the case may be, shall use commercially reasonable efforts
consistent with the Servicing Standard to collect the applicable Operating Advisor Consulting Fee from the related Mortgagor in
connection with such Major Decision, but only to the extent not prohibited by the related Mortgage Loan documents. The Master
Servicer or Special Servicer, as the case may be, may waive or reduce the amount of any Operating Advisor Consulting Fee payable
by the related Mortgagor if it determines that such full or partial waiver is in accordance with the Servicing Standard, but in
no event shall the Master Servicer or the Special Servicer take any enforcement action with respect to the collection of such
Operating Advisor Consulting Fee other than requests for collection; provided that the Master Servicer or the Special Servicer,
as applicable, shall consult, on a non-binding basis, with the Operating Advisor prior to any such waiver or reduction. Notwithstanding
the foregoing, the Operating Advisor will have no obligations or consultation rights in its capacity as operating advisor with
respect to: (i) any Non-Serviced Whole Loan or any related REO Property or (ii) any Serviced AB Whole Loan, prior to the occurrence
and continuance of both an AB Control Appraisal Period and a Control Termination Event; provided, further, that
the Operating Advisor shall not be entitled to an Operating Advisor Consulting Fee with respect to any Non-Serviced Whole Loan.

 

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

 

(k)            After
the occurrence of an Operating Advisor Termination Event, the Trustee may, and upon the written direction of Holders of Certificates
representing at least 25% of the Voting Rights (taking into account the application of any Appraisal Reduction Amounts to

 

     -283-

     

    

 

notionally
reduce the Certificate Balance of the Classes of Certificates), the Trustee shall promptly terminate the Operating Advisor for
cause and appoint a replacement Operating Advisor that is an Eligible Operating Advisor; provided that no such termination
shall be effective until a successor operating advisor has been appointed and has assumed all of the obligations of the Operating
Advisor under this Agreement. No such termination shall terminate, change, reduce, or otherwise modify the rights and obligations
of the Operating Advisor that accrued prior to such termination, including the right to receive all amounts accrued and owing
to it under this Agreement, and other than indemnification rights (arising out of events occurring prior to such termination).
The Trustee may rely on a certification by the replacement Operating Advisor that it is an Eligible Operating Advisor. Upon any
termination of the Operating Advisor and appointment of a successor to the Operating Advisor, the Trustee will, as soon as possible,
be required to give written notice of the termination and appointment to the Special Servicer, the Master Servicer, the Certificate
Administrator, the 17g-5 Information Provider (for posting to the 17g-5 Information Provider’s Website), the Depositor,
the Directing Certificateholder, the Risk Retention Consultation Party, any Companion Loan holder and the Certificateholders.

 

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

 

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

 

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

 

     -284-

     

    

 

(o)            In
the event there are no Classes of Certificates outstanding other than the Control Eligible Certificates, the Class V Certificates,
the Class R Certificates and the RR Interest, then all of the rights and obligations of the Operating Advisor shall terminate
without payment of any termination fee (other than any rights or obligations that accrued prior to the date of such termination
(including accrued and unpaid compensation) and other than indemnification rights arising out of events occurring prior to such
termination). In connection with any termination pursuant to this Section 3.26(o), no successor operating advisor shall
be appointed. Upon receipt of written notice of such acts by a Responsible Officer of the Trustee, the Trustee shall provide the
Operating Advisor with prompt notice upon its termination pursuant to this Section 3.26(o).

 

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

 

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

 

(r)             Neither
the Operating Advisor nor any of its Affiliates shall make any investment in any Class of Certificates; provided, however,
that such prohibition shall not apply to (i) riskless principal transactions effected by a broker-dealer Affiliate of the Operating
Advisor or (ii) investments by an Affiliate of the Operating Advisor if the Operating Advisor and such Affiliate maintain policies
and procedures that (A) segregate personnel involved in the activities of the Operating Advisor under this Agreement from personnel
involved in such Affiliate’s investment activities and (B) prevent such Affiliate and its personnel from gaining access
to information regarding the Trust and the Operating Advisor and its personnel from gaining access to such Affiliate’s information
regarding its investment activities.

 

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

 

(t)             The
Operating Advisor may delegate its duties and obligations to agents or subcontractors so long as the related agreements or arrangements
with such agents or

 

     -285-

     

    

 

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

 

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

 

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

 

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

 

(c)            In
the case of each of the Serviced Companion Loans, upon the resignation or removal of the Master Servicer pursuant to Article
VII of this Agreement, the

 

     -286-

     

    

 

Master Servicer, as the Companion Paying Agent, shall be deemed simultaneously to resign or be
removed.

 

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

 

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

 

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

 

For
the avoidance of doubt, any notices or information required to be delivered pursuant to this Agreement by any party hereto to
a Serviced Companion Noteholder with respect to a Serviced Companion Loan that has been included in an Other Securitization shall
be provided to the Other Servicer under the Other Pooling and Servicing Agreement.

Companion Loans. (a) In the event that any of the applicable Non-Serviced Trustee, the applicable Non-Serviced Master
Servicer or the applicable Non-Serviced Special Servicer shall be replaced in accordance with the terms of the applicable
Non-Serviced PSA, the Master Servicer and the Special Servicer shall acknowledge its successor as the successor to the

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

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

 

     -287-

     

    

 

efforts to cooperate with such Serviced Companion
Noteholder in attempting to cause the related Mortgagor to provide information relating to such Whole Loan and the related notes,
and that such holder reasonably determines to be necessary or appropriate, for inclusion in any disclosure document(s) relating
to such Other Securitization.

 

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

 

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

 

(f)             With
respect to each Mortgage Loan that is part of a 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)            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 Other
Asset Representations Reviewer or any other party to the Other Pooling and Servicing Agreement in connection with such Asset Review
by providing the Other Asset Representations Reviewer or such other requesting party with any documents reasonably requested by
the Other Asset Representations Reviewer 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, but in any event excluding any
documents known to the Master Servicer, the Special Servicer, the Trustee or the Custodian to contain information that is proprietary
to the related originator or Mortgage Loan Seller or any draft documents or privileged or internal communications.

 

(h)            With
respect to any Non-Serviced Mortgage Loan, if the Master Servicer or Special Servicer shall receive any communication from the
applicable Non-Serviced Master Servicer or Non-Serviced Special Servicer regarding any Major Decision pursuant to clause (xii) of the definition of such term, then the Master Servicer or Special Servicer shall forward the communication to the Directing
Certificateholder (and to the Master Servicer, if the Special Servicer is forwarding such communication, and to the Special Servicer
if the Master Servicer is forwarding such communication), and the Special Servicer shall reasonably cooperate with the

 

     -288-

     

    

 

applicable
Non-Serviced Master Servicer or the applicable Non-Serviced Special Servicer, as the case may be, in effecting any action by the
applicable Non-Serviced Master Servicer or the applicable Non-Serviced Special Servicer, in any such case subject to and consistent
with the related Intercreditor Agreement.

 

(i)             During
the period from and after a Serviced Pari Passu Companion Loan is deposited into an Other Securitization, not later than 5:00

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

 

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

 

(c)            The
Special Servicer shall not (i) undertake (or direct the Master Servicer to undertake) any material settlement of any
Trust-Related Litigation or (ii) initiate any material Trust-Related Litigation unless and until it has notified in writing
the Directing Certificateholder (only if the related Mortgage Loan is not an Excluded Loan as to such party and prior to the
occurrence and continuance of a Consultation Termination Event) (to the extent the identity of the Directing
Certificateholder is actually known to the Special Servicer; provided that the Special Servicer shall make due inquiry
of the Certificate Administrator as to the identity of the Directing Certificateholder) and the related holder of any
Serviced Companion Loan (if such matter affects such related Serviced Companion Loan) (to the extent the identity of the
holder of such Serviced Companion Loan is actually known to the Special Servicer), and the Directing Certificateholder (only
if the related Mortgage Loan is not an Excluded Loan with respect to the Directing Certificateholder or the Holder of
the majority of the Controlling Class and prior to the occurrence and continuation of a Control Termination Event) has not
objected in writing within five (5) Business Days of having been notified thereof and having been provided with all
information that the Directing Certificateholder has reasonably requested with respect thereto

 

     -290-

     

    

 

promptly
following its receipt of the subject notice (it being understood and agreed that if such written objection has not been
received by the Special Servicer within such five (5) Business Day period, then the Directing Certificateholder shall be
deemed to have approved the taking of such action); provided that, if the Special Servicer determines (consistent with
the Servicing Standard) that immediate action is necessary to protect the interests of the Certificateholders and, with
respect to a Serviced Whole Loan, the related Companion Holders, the Special Servicer may take such action without waiting
for the Directing Certificateholder’s response.

 

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

 

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

 

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

 

(g)            Notwithstanding
the Master Servicer’s right to make determinations relating to claims against the Master Servicer, the Special Servicer
shall have the right at any time in accordance with the Servicing Standard to (i) direct the Master Servicer to settle any claims
asserted against the Master Servicer (whether or not the Trust or the Special Servicer is named in any such claims or Trust-Related
Litigation) (and with respect to any material settlements, with the consent of or in consultation with the Directing Certificateholder
prior to the occurrence and continuance of a Control Termination Event or the occurrence and continuance of a Consultation Termination
Event, respectively (in each case, other than a Mortgage Loan that is an Excluded Loan as to such party)) and (ii) otherwise reasonably
direct the actions of the Master Servicer relating to claims against the Master Servicer (whether or not the Trust or the Special
Servicer is named in any such claims or Trust-Related Litigation), provided in either case that (A) such settlement or
other direction does not require any admission

 

     -291-

     

    

 

of liability or wrongdoing on the part of the Master Servicer, (B) the cost of
such settlement or any resulting judgment is and shall be paid by the Trust and payment of such cost or judgment is provided for
in this Agreement, (C) the Master Servicer is and shall be indemnified as and to the extent provided in this Agreement for all
costs and expenses of the Master Servicer incurred in defending and settling the Trust-Related Litigation and for any judgment,
(D) any such action taken by the Master Servicer at the direction of the Special Servicer shall be deemed (as to the Master Servicer)
to be in compliance with the Servicing Standard and (E) the Special Servicer provides the Master Servicer with assurance reasonably
satisfactory to the Master Servicer as to the items in clauses (A), (B) and (C).

 

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

 

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

 

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

 

     -292-

     

    

 

Excluded Loan as to such party) from initiating
any action, suit, litigation or proceeding in its name as representative of the Trustee of the Trust.

 

Section
3.33     Delivery of Excluded Information to the Certificate Administrator. Any Excluded
Information that the Master Servicer, the Special Servicer or the Operating Advisor identifies and delivers to the
Certificate Administrator for posting to the Certificate Administrator’s Website shall be delivered to the Certificate
Administrator via e-mail (or such other electronic means as is mutually acceptable to the parties) in one or more separate
files labeled “Excluded Information” followed by the applicable loan name and loan file to
cmbsexcludedinformation@wellsfargo.com. For the avoidance of doubt, any information that is not appropriately labeled and
delivered in accordance with this Section 3.33 shall not be separately posted as Excluded Information on the
Certificate Administrator’s Website, and any information appropriately labeled and delivered to the Certificate
Administrator pursuant to this Section 3.33 shall be posted on the Certificate Administrator’s Website under the
“Excluded Information” section, as provided under Section 3.13. When so posted, the Excluded Controlling
Class Holders shall be prohibited from the access of Excluded Information with respect to any Excluded Controlling Class
Loans on the Certificate Administrator’s Website (unless a loan-by-loan segregation is later performed by the
Certificate Administrator in which case such access shall only be prohibited with respect to the related Excluded Controlling
Class Loans). None of the Master Servicer, the Special Servicer or the Operating Advisor shall have any obligations to
separately label and deliver any Excluded Information in accordance with this Section 3.33 until such party has
received written notice with respect to the related Excluded Controlling Class Loan in the form of Exhibit P-1E to
this Agreement. Nothing set forth in this Agreement shall prohibit the Directing Certificateholder or any Controlling Class
Certificateholder from receiving, requesting or reviewing any Excluded Information relating to any Excluded Controlling Class
Loan with respect to which the Directing Certificateholder or such Controlling Class Certificateholder is not a Borrower
Party and, if such Excluded Information is not available on the Certificate Administrator’s Website, the Directing
Certificateholder or Controlling Class Certificateholder that is not a Borrower Party with respect to the related Excluded
Controlling Class Loan shall be permitted to obtain such information in accordance with Section 4.02(f) of this
Agreement.

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

 

(b)            Distributions
of Retained Certificate Available Funds. On each Distribution Date, to the extent of the Retained Certificate Available Funds
for such Distribution Date, the Certificate Administrator shall be deemed to transfer the Lower-Tier Distribution Amount from
the Lower-Tier REMIC Distribution Account to the Upper-Tier REMIC Distribution Account in the amounts and priorities set forth
in Section 4.01(c) with respect to the LRR Uncertificated Interest, and immediately thereafter, shall make distributions
thereof from the Upper-Tier REMIC Distribution Account in the following order of priority, satisfying in full, to the extent required
and possible, each priority before making any distribution with respect to any succeeding priority:

 

     -297-

     

    

 

(i)              first,
to the Holders of the RR Interest, in respect of interest, up to an amount equal to the Retained Certificate Interest Distribution
Amount for such Distribution Date;

 

(ii)            second,
to the Holders of the RR Interest, in reduction of the Certificate Balance thereof, an amount equal to the Retained Certificate
Principal Distribution Amount for such Distribution Date, until the outstanding Certificate Balance of the RR Interest has been
reduced to zero; and

 

(iii)           third,
to the Holders of the RR Interest, up to an amount equal to the unreimbursed Retained Certificate Realized Losses previously allocated
to such Class, plus interest in an amount equal to the Retained Certificate Realized Loss Interest Distribution Amount for such
Distribution Date;

 

provided,
however, that to the extent any Retained Certificate Available Funds remain in the Upper-Tier REMIC Distribution Account
after applying amounts as set forth in clauses (i) – (iii) above, any such amounts so remaining shall be disbursed
to the Holders of the Class R Certificates in respect of the Class UR Interest.

 

(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 or Retained Certificate Realized Losses, as applicable, in an amount equal to the amount of principal or reimbursement
of Realized Losses or Retained Certificate Realized Losses, as applicable, actually distributable to the Holders of the respective
Related Certificates as provided in Sections 4.01(a), 4.01(b), 4.01(d), 4.01(f) and 4.01(i)
such that at all times the Lower-Tier Principal Amount of each Class of Lower-Tier Regular Interests is equal to the Certificate
Balance of the Class of Related Certificates. On each Distribution Date, each Lower-Tier Regular Interest shall be deemed to receive
distributions in respect of interest in an amount equal to the Interest Distribution Amount or Retained Certificate Interest Distribution
Amount, as applicable, in respect of its Related Certificates plus (A) a pro rata portion of the Interest Distribution
Amount in respect of (i) in the case of the Class LA1, Class LA2, Class LASB, Class LA3 and Class LA4 Uncertificated Interests,
the Class X-A Certificates, (ii) in the case of the Class LAS and Class LB Uncertificated Interests, the Class X-B Certificates,
(iii) in the case of the Class LD Uncertificated Interest, the Class X-D Certificates, (iv) in the case of the Class LE Uncertificated
Interest, the Class X-E Certificates, (v) in the case of the Class LF Uncertificated Interest, the Class X-F Certificates, and
(vi) in the case of the Class LG Uncertificated Interest, the Class X-G Certificates, and (B) in the case of the LRR Uncertificated
Interest, the Retained Certificate Interest Distribution Amount in respect of the RR Interest, in each case, computed based on
an interest rate equal to the excess of the Weighted Average Net Mortgage Rate over the Pass-Through Rate of the Related Certificates
and a notional amount equal to its related Lower-Tier Principal Amount, in each case to the extent actually distributable thereon
as provided in Section 4.01(a) or 4.01(b), as applicable. 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.

 

     -298-

     

    

 

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 and Retained Certificate Realized Losses, as provided
in Sections 4.04(b) and 4.04(c). The initial principal balance of each Lower-Tier Regular Interest shall equal the
respective Original Lower-Tier Principal Amount. The Pass-Through Rate with respect to each Lower-Tier Regular Interest for any
Distribution Date shall be the Weighted Average Net Mortgage Rate for such Distribution Date.

 

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

 

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

 

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

 

     -299-

     

    

 

For
purposes of the first paragraph of this Section 4.01(e), the relevant “Base Interest Fraction” in connection
with any Principal Prepayment of any Mortgage Loan that provides for the payment of a Yield Maintenance Charge or Prepayment Premium,
and with respect to any Class of Principal Balance Certificates (other than the RR Interest), shall be a fraction (A) the numerator
of which is the greater of (x) zero and (y) the difference between (i) the Pass-Through Rate on such Class for the related Distribution
Date, and (ii) the applicable Discount Rate and (B) the denominator of which is the difference between (i) the Mortgage Rate on
such Mortgage Loan and (ii) the applicable Discount Rate; provided that: (a) under no circumstances will the Base Interest
Fraction be greater than 1.0; (b) if the applicable Discount Rate is greater than or equal to the Mortgage Rate on such Mortgage
Loan and is greater than or equal to the Pass-Through Rate on such Class for the related Distribution Date, then the Base Interest
Fraction will equal zero; and (c) if the applicable Discount Rate is greater than or equal to the Mortgage Rate on such Mortgage
Loan and is less than the Pass-Through Rate on such Class for the related Distribution Date, then the Base Interest Fraction shall
be equal to 1.0. If a Mortgage Loan provides for a step-up in the Mortgage Rate, then the Mortgage Rate used in the determination
of the Base Interest Fraction will be the Mortgage Rate in effect at the time of the prepayment.

 

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

 

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

 

     -300-

     

    

 

All
distributions of Yield Maintenance Charges and Prepayment Premiums made in respect of the respective Classes of Regular
Certificates on each Distribution Date pursuant to Section 4.01(e) shall first be deemed to be distributed from
the Lower-Tier REMIC to the Upper-Tier REMIC in respect of the Lower-Tier Regular Interests, pro rata based upon the
amount of principal distributed in respect of each such Class of Lower-Tier Regular Interests for such Distribution Date
pursuant to Section 4.01(c) above.

 

(f)             On
each Distribution Date, the Certificate Administrator shall (i) withdraw amounts from the Gain-on-Sale Reserve Account and shall
distribute such amounts to reimburse the Holders of the Regular Certificates (other than the RR Interest) (in order of distribution
priority) (first deeming such amounts to be distributed with respect to the Related Lower Tier Regular Interests) up to an amount
equal to all Realized Losses, if any, previously deemed allocated to them and unreimbursed after application of the Available
Funds for such Distribution Date and (ii) withdraw amounts from the Retained Certificate Gain-on-Sale Reserve Account and shall
distribute such amounts to reimburse the Holders of the RR Interest (first deeming such amounts to be distributed with respect
to the Related Lower Tier Regular Interests) up to an amount equal to all Retained Certificate Realized Losses, if any, previously
deemed allocated to them and unreimbursed after application of the Retained Certificate Available Funds for such Distribution
Date. Amounts paid from the Gain-on-Sale Reserve Account and the Retained Certificate Gain-on-Sale Reserve Account shall not reduce
the Certificate Balances of the Classes of Certificates receiving such distributions. Any amounts remaining in the Gain-on-Sale
Reserve Account and the Retained Certificate Gain-on-Sale Account after such distributions shall be applied to offset future Realized
Losses and Retained Certificate Realized Losses, as applicable, with respect to the Principal Balance Certificates and related
Realized Losses and Retained Certificate Realized Losses, as applicable, in each case allocable to the Regular Certificates. Upon
termination of the Trust, any amounts remaining in the Gain-on-Sale Reserve Account and the Retained Certificate Gain-on-Sale
Reserve Account shall be distributed to the Holders of the Class R Certificates from the Lower-Tier REMIC in respect of the Class
LR Interest.

 

(g)            All
distributions made with respect to each Class of Certificates on each Distribution Date shall be allocated pro rata among
the outstanding Certificates in such Class based on their respective Percentage Interests. Except as otherwise specifically provided
in Sections 4.01(h), 4.01(i) and 9.01, all such distributions with respect to each Class on each Distribution
Date shall be made to the Certificateholders of the respective Class of record at the close of business on the related Record
Date and shall be made by wire transfer of immediately available funds to the account of any such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such Certificateholder shall have provided the Certificate Administrator
with wiring instructions no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be
in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate (determined without regard to any possible
future reimbursement of Realized Losses or Retained Certificate Realized Losses, as applicable, 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.

 

     -301-

     

    

 

Each
distribution with respect to a Book-Entry Certificate shall be paid to the Depository, as Holder thereof, and the Depository shall
be responsible for crediting the amount of such distribution to the accounts of its Depository Participants in accordance with
its normal procedures. Each Depository Participant shall be responsible for disbursing such distribution to the Certificate Owners
that it represents and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating
firm”) for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Certificate Owners
that it represents. None of the Trustee, the Certificate Administrator, the Certificate Registrar, the Depositor, the Master Servicer,
the Special Servicer or the Underwriters shall have any responsibility therefor except as otherwise provided by this Agreement
or applicable law.

 

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

 

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

 

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

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 4.01(h) shall not have been surrendered for cancellation within six (6) months after the
time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non-tendering Certificateholders
to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one
(1) year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator,
directly or through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender
of their Certificates as it shall deem appropriate, such to applicable law with respect to escheatment of funds. The costs and
expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery
of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be
payable to any Certificateholder on any amount held in trust hereunder by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 4.01(h).

 

     -302-

     

    

 

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

 

(j)             On
each Distribution Date, any Excess Interest received during the related Collection Period with respect to any ARD Loans shall
be distributed (i) to the Holders of the Excess Interest Certificates in an amount equal to the Non-Retained Percentage of such
Excess Interest and (ii) to the Holders of the RR Interest in an amount equal to the Required Credit Risk Retention Percentage
of such Excess Interest, in each case, from the Excess Interest Distribution Account. Excess Interest will not be available to
pay any other amounts except for distributions on Excess Interest Certificates and the RR Interest as set forth in the prior sentence.

 

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

 

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

 

(ii)            to
the extent permitted under the related Intercreditor Agreement and not otherwise previously reimbursed, to pay the Trustee or
the Certificate Administrator or any of their directors, officers, employees and agents, as the case may be, any amounts payable
or reimbursable to any such Person pursuant to Section 8.05, to the extent any such amounts relate solely to a Serviced
Whole Loan related to such Companion Loan, and such amounts are to be paid by the related Companion Holder pursuant to the related
Intercreditor Agreement;

 

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

 

     -303-

     

    

 

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

 

All
distributions from the Companion Distribution Account required hereunder shall be made by the Companion Paying Agent to the related
Companion Holder by wire transfer in immediately available funds on each Serviced Whole Loan Remittance Date (and on each additional
date required by this Agreement or the related Intercreditor Agreement) to the account of such Companion Holder or an agent therefor
appearing on the Serviced Companion Noteholder Register on the related Record Date (or, if no such account so appears or information
relating thereto is not provided at least five (5) Business Days prior to the related Record Date, by check sent by first class
mail to the address of such Companion Holder or its agent appearing on the Serviced Companion Noteholder Register). Any such account
shall be located at a commercial bank in the United States.

 

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

and (y)(i) unless Wells Fargo Bank, National Association, Bank of America, National Association or Morgan Stanley Bank, N.A. has
provided notice to the contrary in respect of such party, a statement (without verification) that the RR Interest of each of Wells

in the case that the Certificate Administrator receives a notification that any such party has failed to comply with the covenant
pursuant to Section 3(ii) of the EU Risk Retention Agreement, a statement of such non-compliance and all details in relation

(b)            [RESERVED].

 

(c)            Each
of the Master Servicer and the Special Servicer may, at its sole cost and expense, make available by electronic media, bulletin
board service or Internet website (in addition to making information available as provided herein) any reports or other information
the Master Servicer or the Special Servicer, as applicable, is required or permitted to provide to any party to this Agreement,
the Rating Agencies or any Certificateholder or any prospective Certificateholder that has provided the Master Servicer or the
Special Servicer, as applicable, with an Investor Certification or has executed a “click-through” confidentiality
agreement in accordance with Section 3.13 (which may be a licensed or registered investment advisor) to the extent such
action does not conflict with the terms of this Agreement (including without limitation, any requirements to keep Privileged Information
confidential), the terms of the Mortgage Loans or applicable law. Notwithstanding this paragraph, the availability of such information
or reports on the Internet or similar electronic media shall not be deemed to satisfy any specific delivery requirements in this
Agreement except as set forth herein. In connection with providing access to the Master Servicer’s Internet website, the
Master Servicer shall take reasonable measures to ensure that only such parties listed above may access such information including,
without limitation, requiring registration, a confidentiality agreement and acceptance of a disclaimer. Neither the Master Servicer
nor the Special Servicer, as the case may be, shall be liable for dissemination of this information in accordance with this Agreement,
and neither the Master Servicer nor the Special Servicer shall be responsible for any information delivered, produced, or made
available pursuant to Section 3.13 and Section 4.02(a), other than information produced by the Master Servicer or
the Special Servicer, as applicable; provided that such information otherwise meets the requirements set forth herein with
respect to the form and substance of such information or reports. The Master Servicer shall be entitled to attach to any report
provided pursuant to this Section 4.02(c), any reasonable disclaimer with respect to information provided, or any assumptions
required to be made by such report.

 

The
Special Servicer shall from time to time (and, in any event, as may be reasonably required by the Master Servicer) provide the
Master Servicer with such information in its possession regarding the Specially Serviced Loans and REO Properties as may be necessary
for the Master Servicer to prepare each report and any supplemental information to be provided by the Master Servicer to the Certificate
Administrator. None of the Certificate Administrator, the Trustee or the Depositor shall have any obligation to recompute, verify
or recalculate the information provided thereto by the Master Servicer. Unless the Certificate Administrator has actual knowledge
that any report or file received from the Master Servicer contains erroneous information, the Certificate Administrator is authorized
to rely thereon in calculating and making distributions to Certificateholders in accordance with Section 4.01, preparing
the Distribution Date Statement required by Section 4.02(a) and allocating Realized Losses and/or Retained Certificate
Realized Losses, as applicable, to the Certificates in accordance with Section 4.04.

 

Notwithstanding
the foregoing, the failure of the Master Servicer or the Special Servicer to disclose any information otherwise required to be
disclosed pursuant to this Section 4.02(c) or Section 4.02(d) shall not constitute a breach of this Section 4.02(c)
or of Section 4.02(d) to the extent the Master Servicer or Special Servicer so fails because such disclosure, in the
reasonable belief of the Master Servicer or the Special Servicer, as the case

 

     -309-

     

    

 

may be, would violate any applicable law or any
provision of a Mortgage Loan document prohibiting disclosure of information with respect to the Mortgage Loans or the Mortgaged
Properties. The Master Servicer or the Special Servicer may affix to any information provided by it any disclaimer it deems appropriate
in its reasonable discretion (without suggesting liability on the part of any other party hereto).

 

(d)            Upon
the written request of a Certificateholder, any beneficial owner of a Certificate, or any prospective purchaser of a Certificate
that is a Qualified Institutional Buyer and is designated by a Certificateholder or a beneficial owner of a Certificate as such
and, in any case, has delivered an Investor Certification to the Depositor and the Certificate Administrator, as soon as reasonably
practicable, at the expense of the requesting party, the Certificate Administrator shall make available to the requesting party
such information that is in the Certificate Administrator’s possession or can reasonably be obtained by the Certificate
Administrator as is requested by such person, for purposes of satisfying applicable reporting requirements under Rule 144A under
the Securities Act. Neither the Certificate Registrar, nor the Certificate Administrator shall have any responsibility for the
sufficiency under Rule 144A or any other securities laws of any available information so furnished to any person including any
prospective purchaser of a Certificate or any interest therein, nor for the content or accuracy of any information so furnished
which was prepared or delivered to them by another.

 

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

 

(f)            Upon
the reasonable request of the Directing Certificateholder or any Controlling Class Certificateholder that, in either case, is
an Excluded Controlling Class Holder with respect to any Excluded Controlling Class Loan identified to the Master Servicer’s
(in the case of a Non-Specially Serviced Loan) or the Special Servicer’s (in the case of a Specially Serviced Loan) reasonable
satisfaction (at the expense of the Directing Certificateholder or such Controlling Class Certificateholder) and if such information
is in the Master Servicer’s or the Special Servicer’s possession, as applicable, the Master Servicer or the Special
Servicer shall provide or make available (or forward electronically) to the Directing Certificateholder or such Controlling Class
Certificateholder, as applicable, (at the expense of the Directing Certificateholder or such Controlling Class Certificateholder,
as applicable) any Excluded Information (available to Privileged Persons through the Certificate Administrator’s Website
but not accessible to the Directing Certificateholder or such Controlling Class Certificateholder, as applicable, through the
Certificate Administrator’s Website because the Directing Certificateholder or such Controlling Class Certificateholder,
as applicable, is an Excluded Controlling Class Holder with respect to another Excluded Controlling Class Loan) relating to any
Excluded Controlling Class Loan with respect to which the Directing Certificateholder or such Controlling Class Certificateholder,
as applicable, is not a Borrower Party; provided that, in connection therewith, the Master Servicer or the Special Servicer
may require a written confirmation executed by the requesting Person substantially in such form as may be reasonably acceptable
to the Master Servicer or the Special Servicer, generally to the effect that such Person is the Directing Certificateholder or
a Controlling Class Certificateholder, will keep such

 

     -310-

     

    

 

Excluded Information confidential and is not a Borrower Party, upon which
the Master Servicer or the Special Servicer may conclusively rely. In addition, the Master Servicer and the Special Servicer shall
be entitled to conclusively rely on delivery from the Directing Certificateholder or a Controlling Class Certificateholder, as
applicable, of an Investor Certification substantially in the form of Exhibit P-1B that the Directing Certificateholder
or Controlling Class Certificateholder is not an Excluded Controlling Class Holder with respect to a particular Mortgage Loan.
For the avoidance of doubt, the Special Servicer referenced in this Section 4.02(f) shall include any applicable Excluded
Special Servicer with respect to the related Excluded Special Servicer Loan(s).

 

Section
4.03     P&I Advances. (a) On or before 4:00 p.m., New York City time, on each P&I
Advance Date, the Master Servicer shall (i) remit to the Certificate Administrator for deposit from its own funds into the
Lower-Tier REMIC Distribution Account, an amount equal to the aggregate amount of P&I Advances, if any, with respect to
the Mortgage Loans to be made in respect of the related Distribution Date, (ii) apply amounts held in the Collection Account,
for future distribution to Certificateholders in subsequent months in discharge of any such obligation to make P&I
Advances or (iii) make P&I Advances in the form of any combination of (i) and (ii) aggregating the total amount of
P&I Advances to be made. Any amounts held in the Collection Account for future distribution and so used to make P&I
Advances shall be appropriately reflected in the Master Servicer’s records and replaced by the Master Servicer by
deposit in the Collection Account on or before the next succeeding P&I Advance Date (to the extent not previously
replaced through the deposit of Late Collections of the delinquent principal and/or interest in respect of which such P&I
Advances were made). The Master Servicer shall notify the Certificate Administrator of (i) the aggregate amount of P&I
Advances for a Distribution Date and (ii) the amount of any Nonrecoverable P&I Advances for such Distribution Date, on or
before two (2) Business Days prior to such Distribution Date. If the Master Servicer fails to make a required P&I Advance
by 4:00 p.m., New York City time, on any P&I Advance Date, the Trustee shall make such P&I Advance pursuant to Section
7.05 by noon, New York City time, on the related Distribution Date, unless the Master Servicer shall have cured such
failure (and provided written notice of such cure to the Trustee and the Certificate Administrator) by 11:00 a.m., New York
City time, on such Distribution Date. In the event that the Master Servicer fails to make a required P&I Advance
hereunder, the Certificate Administrator shall notify the Trustee of such circumstances by 4:30 p.m., New York City time, on
the related P&I Advance Date. Notwithstanding the foregoing, the portion of any P&I Advance equal to the
CREFC® Intellectual Property Royalty License Fee shall not be remitted to the Certificate Administrator for
deposit into the Lower-Tier REMIC Distribution Account but shall be deposited into the Collection Account for payment to
CREFC® on such Distribution Date.

 

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

 

If
the Master Servicer or the Trustee makes a P&I Advance with respect to a Non-Serviced Mortgage Loan, then it shall provide
to the related Non-Serviced Master Servicer and

 

     -311-

     

    

 

Non-Serviced Trustee written notice of the amount of such P&I Advance within
two (2) Business Days of making such P&I Advance.

 

(b)            Subject
to Section 4.03(c) and Section 4.03(e) below, the amount of P&I Advances to be made by the Master Servicer
with respect to any Distribution Date, and each Mortgage Loan, shall be equal to: (i) the Periodic Payments (net of related
Servicing Fees and, in the case of any Non-Serviced Mortgage Loan, a fee accruing at the related Non-Serviced Primary
Servicing Fee Rate) other than Balloon Payments, that were due on the Mortgage Loan (including any Non-Serviced Mortgage
Loan) and any REO Loan (other than any portion of an REO Loan related to a Companion Loan) during the related Collection
Period and were not received as of the close of business on the Business Day preceding the related P&I Advance Date (or
not advanced by any Sub-Servicer on behalf of the Master Servicer) and (ii) with respect to each Mortgage Loan delinquent in
respect of its Balloon Payment as of the P&I Advance Date (including any REO Loan (other than any portion of an REO Loan
related to a Companion Loan) as to which the related Balloon Payment would have been past due), an amount equal to the
Assumed Scheduled Payment therefor. Subject to Section 4.03(c) below, the obligation of the Master Servicer to make
such P&I Advances is mandatory, and with respect to any Mortgage Loan (including any Non-Serviced Mortgage Loan) or REO
Loan (other than any portion of an REO Loan related to a Companion Loan), shall continue until the Distribution Date on which
the proceeds, if any, received in connection with a Liquidation Event or the disposition of the REO Property, as the case may
be, with respect thereto are to be distributed. No P&I Advances shall be made with respect to any Companion
Loan.

 

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

 

     -312-

     

    

 

to the related Serviced Mortgage Loan unless and until the Master Servicer or the Trustee, as the case may be, determines that
any such additional P&I Advances with respect to the related Serviced Mortgage Loan would not be a Nonrecoverable P&I
Advance, which determination may be as a result of consultation with the related Other Servicer, as the case may be, or otherwise.
For the avoidance of doubt, the Master Servicer, the Special Servicer or the Trustee, as the case may be, shall have the sole
discretion provided in this Agreement to determine that any future P&I Advance or outstanding P&I Advance would be, or
is, as applicable, a Nonrecoverable Advance.

 

With
respect to each Non-Serviced Mortgage Loan, the Master Servicer, the Special Servicer or the Trustee shall make its determination
(based on information provided by the applicable Non-Serviced Master Servicer and Non-Serviced Special Servicer) that a P&I
Advance that has been made on such Non-Serviced Mortgage Loan is a Nonrecoverable Advance or that any proposed P&I Advance
would, if made, constitute a Nonrecoverable Advance with respect to such Non-Serviced Mortgage Loan independently of any determination
made by the applicable Non-Serviced Master Servicer, the applicable Non-Serviced Special Servicer or the Non-Serviced Trustee,
as the case may be, under the applicable Non-Serviced PSA in respect of the related Non-Serviced Companion Loan. If the Master
Servicer, the Special Servicer or the Trustee determines that a proposed P&I Advance with respect to a Non-Serviced Mortgage
Loan, if made, or any outstanding P&I Advance with respect to a Non-Serviced Mortgage Loan previously made, would be, or is,
as applicable, a Nonrecoverable Advance, the Master Servicer, the Special Servicer or the Trustee, as applicable, shall provide
the applicable Non-Serviced Master Servicer and Non-Serviced Special Servicer written notice of such determination within two
(2) Business Days of the date of such determination. If the Master Servicer receives written notice from the related Non-Serviced
Master Servicer or the related Non-Serviced Special Servicer, as the case may be, that either has determined, or the Non-Serviced
Trustee has determined, in accordance with the applicable Non-Serviced PSA with respect to a Non-Serviced Companion Loan, that
any proposed advance under the applicable Non-Serviced PSA that is similar to a P&I Advance would be, or any outstanding advance
under such Non-Serviced PSA that is similar to a P&I Advance is, a nonrecoverable advance, then the Master Servicer, the Special
Servicer or the Trustee may, based upon such determination, determine that any P&I Advance previously made or proposed to
be made with respect to the related Non-Serviced Mortgage Loan will be a Nonrecoverable P&I Advance. Thereafter, in either
case, the Master Servicer and the Trustee shall not be required to make any additional P&I Advances with respect to the related
Non-Serviced Mortgage Loan unless and until the Master Servicer or the Trustee, as the case may be, determines that any such additional
P&I Advances with respect to the related Non-Serviced Mortgage Loan would not be a Nonrecoverable P&I Advance, which determination
may be as a result of consultation with the related Non-Serviced Master Servicer or the related Non-Serviced Special Servicer,
as the case may be, or otherwise. For the avoidance of doubt, the Master Servicer, the Special Servicer or the Trustee, as the
case may be, shall have the sole discretion provided in this Agreement to determine that any future P&I Advance or outstanding
P&I Advance would be, or is, as applicable, a Nonrecoverable Advance.

 

(d)            In
connection with the recovery of any P&I Advance out of the Collection Account, pursuant to Section 3.05(a), the Master
Servicer shall be entitled to pay the Trustee and itself (in that order of priority) as the case may be, out of any amounts then
on deposit in the

 

     -313-

     

    

 

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

 

(e)            Notwithstanding
the foregoing, (i) neither the Master Servicer nor the Trustee shall make an advance for Excess Interest, Yield Maintenance Charges,
Default Interest, late payment charges, Prepayment Premiums, or Balloon Payments or make any P&I Advance with respect to any
Companion Loan and (ii) if an Appraisal Reduction Amount has been determined with respect to any Mortgage Loan (or, in the case
of a Non-Serviced Whole Loan, an “appraisal reduction amount” (or similar item) has been made in accordance with the
related Non-Serviced PSA and the Master Servicer has notice of such appraisal reduction amount) then in the event of subsequent
delinquencies thereon, the interest portion of the P&I Advance in respect of such Mortgage Loan for the related Distribution
Date shall be reduced (it being herein acknowledged that there shall be no reduction in the principal portion of such P&I
Advance) to equal the product of (x) the amount of the interest portion of such P&I Advance for such Mortgage Loan for such
Distribution Date without regard to this clause 4.03(e)(ii), and (y) a fraction, expressed as a percentage, the numerator
of which is equal to the Stated Principal Balance of such Mortgage Loan immediately prior to such Distribution Date, net of the
related Appraisal Reduction Amount (or, in the case of a Serviced Whole Loan, the portion of such Appraisal Reduction Amount allocated
to the related Mortgage Loan), if any, and the denominator of which is equal to the Stated Principal Balance of such Mortgage
Loan immediately prior to such Distribution Date. For purposes of the immediately preceding sentence, the Periodic Payment due
on the Maturity Date for a Balloon Mortgage Loan will be the Assumed Scheduled Payment for the related Distribution Date.

 

Section
4.04     Allocation of Realized Losses. (a) On each Distribution Date, immediately following
the distributions to be made on such date pursuant to Section 4.01, the Certificate Administrator shall calculate the
Realized Loss and Retained Certificate Realized Loss for such Distribution Date. Any allocation of Realized Losses or
Retained Certificate Realized Losses to a Class of Regular Certificates shall be made by reducing the Certificate Balance
thereof by the amount so allocated. Any Realized Losses or Retained Certificate Realized Losses so allocated to a Class of
Regular Certificates shall be allocated among the respective Certificates of such Class in proportion to the Percentage
Interests evidenced thereby. The allocation of Realized Losses or Retained Certificate Realized Losses shall constitute an
allocation of losses and other shortfalls experienced by the Trust. Reimbursement of previously allocated Realized Losses and
Retained Certificate Realized Losses will not constitute distributions of principal for any purpose and will not result in an
additional reduction in the Certificate Balance of the applicable Class of Certificates in respect of which any such
reimbursement is made. With respect to any Class of Principal Balance Certificates, to the

 

     -314-

     

    

 

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 Aggregate Principal Distribution
Amount (and corresponding to a reduction of the Principal Distribution Amount and Retained Certificate 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 Retained
Certificate Realized Losses, as applicable, and in the case of Realized Losses, in sequential order according to the priority
of payments for the Principal Balance Certificates (other than the RR Interest) (and in the case of the Principal Balance Certificates
that are Senior Certificates, on a pro rata basis according to the amount of unreimbursed Realized Losses on such Classes),
in each case up to the amount of the unreimbursed Realized Losses and Retained Certificate Realized Losses, as applicable, allocated
to such Class of Principal Balance Certificates.

 

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

 

(ii)            On
each Distribution Date, the Certificate Balance of the RR Interest will be reduced without distribution, as a write-off to the
extent of any Retained Certificate Realized Losses with respect to such Distribution Date.

 

(c)            With
respect to any Distribution Date, any Realized Losses or Retained Certificate 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 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, Allocated Cumulative Appraisal Reduction Amounts (with respect to a Serviced Whole Loan, to the extent allocated to
the related Mortgage Loan) shall be allocated to each Class of Certificates (other than the RR Interest) 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 G Certificates, second, to the Class F Certificates, third,
to the Class E Certificates, fourth, to the Class D Certificates, fifth, to the Class C Certificates, sixth,
to the Class B Certificates, seventh, to the Class A-S Certificates, and finally, pro rata based on
their respective interest entitlements, to the Senior Certificates (other than the Class X-A, Class X-B, Class X-D, Class X-E, Class X-F and Class X-G Certificates).

 

Appraisal
Reduction Amounts and Cumulative Appraisal Reduction Amounts allocated to a related Mortgage Loan will be allocated between the
RR Interest on the one hand and the Senior Certificates and Subordinate Certificates, on the other hand, based on the Required
Credit Risk Retention Percentage and the Non-Retained Percentage, respectively.

 

     -315-

     

    

 

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

 

For
purposes of determining the Controlling Class and whether a Control Termination Event has occurred and is continuing, Collateral
Deficiency Amounts allocated to an AB Modified Loan will be allocated to each Class of Control Eligible Certificates in Reverse
Sequential Order to notionally reduce the related Certificate Balances until the Certificate Balance of each such Class of Control
Eligible Certificates is reduced to zero. For the avoidance of doubt, for purposes of determining the Controlling Class or the
occurrence and continuance of a Control Termination Event, any Class of Control Eligible Certificates shall be allocated both
applicable Appraisal Reduction Amounts and applicable Collateral Deficiency Amounts (the sum of which shall constitute the applicable
Cumulative Appraisal Reduction Amount), in accordance with this Section 4.05(a), but only to the extent of the Allocated
Appraisal Reduction Amounts and Allocated Cumulative Appraisal Reduction Amounts.

 

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

 

The
Special Servicer shall promptly notify the Master Servicer and the Certificate Administrator, to the extent it receives such information,
of the amount of any Appraisal Reduction Amount, any Collateral Deficiency Amount and any resulting Cumulative Appraisal

 

     -316-

     

    

 

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

 

(b)            (i)
The Holders of the majority of Voting Rights of any Class of Control Eligible Certificates that is determined at any time of determination
to no longer be the Controlling Class (any such Class, an “Appraised-Out Class”) as a result of an Appraisal
Reduction Amount or Collateral Deficiency Amount (as applicable) in respect of such Class shall have the right, at their sole
expense, to require the Special Servicer to order a second Appraisal with respect to any Mortgage Loan (or Serviced Whole Loan)
for which an Appraisal Reduction Event has occurred or as to which there exists a Collateral Deficiency Amount (such Holders,
the “Requesting Holders”). The Special Servicer shall use its reasonable best efforts to ensure that such second
Appraisal is delivered within thirty (30) days from receipt of the Requesting Holders’ written request and shall ensure
that such Appraisal is 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, shall recalculate the Appraisal
Reduction Amount or Collateral Deficiency Amount, as applicable, based on such supplemental Appraisal and any information received
from the Master Servicer. If required by such recalculation, the Appraised-Out Class shall be reinstated as the Controlling Class
and each 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, Allocated Appraisal Reduction Amount or Collateral Deficiency
Amount, as applicable. 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 is
warranted or (B) the

 

     -317-

     

    

 

Special Servicer recalculates the Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable,
based on the supplemental Appraisal, the “Appraisal Review Period”). The rights of the Controlling Class during
each Appraisal Review Period shall be exercised by the next most senior Class of Control Eligible Certificates that is not an
Appraised-Out Class, if any.

 

(c)            With
respect to each Mortgage Loan (other than a Non-Serviced Mortgage Loan), and each Serviced Whole Loan as to which an Appraisal
Reduction Event has occurred (unless such Mortgage Loan or Serviced Whole Loan has become a Corrected Loan (for such purposes
taking into account any amendment or modification of such Mortgage Loan, any related Companion Loan or Serviced Whole Loan)),
the Special Servicer shall (1) within thirty (30) days of the occurrence or of each anniversary of the related Appraisal Reduction
Event, and (2) upon its determination that the value of the related Mortgaged Property has materially changed, notify the Master
Servicer of the occurrence of such anniversary or determination and order an Appraisal (which may be an update of a prior Appraisal),
the cost of which shall be paid by the Master Servicer as a Servicing Advance or to the extent it would be a Nonrecoverable Advance,
an expense of the Trust, or conduct an internal valuation, as applicable and, promptly following receipt of any such Appraisal
or performance of such valuation (or receipt of any Appraisal obtained in accordance with Section 4.05(b) above), shall
deliver a copy thereof to the Master Servicer, the Certificate Administrator, the Trustee, the Operating Advisor and ((i) prior
to the occurrence and continuance of any Consultation Termination Event and (ii) other than with respect to any Mortgage Loan
that is an Excluded Loan as to such party) the Directing Certificateholder. Based upon such Appraisal or internal valuation (or
any Appraisal obtained in accordance with Section 4.05(b) above), the Special Servicer shall determine or redetermine,
as applicable, and report to the Master Servicer, the Certificate Administrator, the Trustee, the Operating Advisor and ((i) prior
to the occurrence and continuance of any Consultation Termination Event and (ii) other than with respect to any Mortgage Loan
that is an Excluded Loan as to such party) the Directing Certificateholder, the amount and calculation or recalculation of the
Appraisal Reduction Amount or Collateral Deficiency Amount with respect to such Mortgage Loan, Companion Loan or Serviced Whole
Loan, as applicable, and such report shall be delivered in the CREFC® Appraisal Reduction Template format; provided,
however, that the Special Servicer shall not be liable for failure to comply with such duties insofar as such failure results
from a failure of the Master Servicer to provide sufficient information to the Special Servicer to comply with such duties or
failure by the Master Servicer to otherwise comply with its obligations hereunder. Following the Master Servicer’s receipt
from the Special Servicer of the calculation of the Appraisal Reduction Amounts, the Master Servicer shall provide such information
to the Certificate Administrator in the form of the CREFC® Loan Periodic Update File, and the Certificate Administrator
will calculate the Allocated Appraisal Reduction Amount and the Allocated Cumulative Appraisal Reduction Amount. Such report of
the Appraisal Reduction Amount shall also be promptly forwarded by the Master Servicer (or the Special Servicer if the related
Mortgage Loan is a Specially Serviced Loan), to the extent the related Serviced Companion Loan has been included in an Other Securitization,
to the Other Servicer and Other Trustee of such Other Securitization into which the related Serviced Companion Loan has been sold,
or to the holder of any related Serviced Companion Loan by the Master Servicer (or the Special Servicer if the related Mortgage
Loan is a Specially Serviced Loan). If the Special Servicer is required to redetermine the Appraisal Reduction Amount or Collateral
Deficiency Amount, such redetermined Appraisal Reduction

 

     -318-

     

    

 

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

 

The
Master Servicer shall deliver by electronic mail to the Special Servicer any information in its possession that is reasonably
required to determine, calculate, redetermine or recalculate any Appraisal Reduction Amount and Allocated Appraisal Reduction
Amount, using reasonable efforts to deliver such information, within four (4) Business Days following the Special Servicer’s
reasonable request therefor; provided that the Special Servicer’s failure to timely make such request shall not relieve
the Master Servicer of its obligation to use reasonable efforts to provide such information to the Special Servicer within four
(4) Business Days following the Special Servicer’s reasonable request. The Master Servicer shall not calculate Appraisal
Reduction Amounts.

 

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

 

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

 

     -319-

     

    

 

the related Serviced AB
Mortgage Loan and any Serviced Pari Passu Companion Loans. Any Appraisal Reduction Amount in respect of any Serviced Pari Passu
Whole Loan will be allocated in accordance with the related Intercreditor Agreement or, if no allocation is specified in the related
Intercreditor Agreement, then, pro rata, between the related Serviced Pari Passu Mortgage Loan and the related Serviced
Pari Passu Companion Loan, based upon their respective outstanding principal balances.

 

Section
4.06     Grantor Trust Reporting. (a) The parties intend that the portions of the Trust Fund
constituting the Grantor Trust, shall constitute, and that the affairs of the Grantor Trust shall be conducted so as to
qualify such portion as, a “grantor trust” under subpart E, part I of subchapter J of the Code, and the
provisions hereof shall be interpreted consistently with this intention. In furtherance of such intention, neither the
Trustee nor the Certificate Administrator shall have the power to vary the investment of the Holders of the Class V
Certificates or the RR Interest 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 V Certificates and the RR Interest, 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)            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 Hare & Co. LLC is the only
“middleman” as defined in the WHFIT Regulations unless the Depositor provides the Certificate Administrator with the
identities of other “middlemen” that are Certificateholders. The Certificate Administrator shall be entitled to indemnification
in accordance with the terms of this Agreement in the event that the Internal Revenue Service makes a determination that the first
sentence of this paragraph is incorrect.

 

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

 

(d)            The
Certificate Administrator shall not be liable for failure to meet the reporting requirements of the WHFIT Regulations nor for
any penalties thereunder if such failure is due to: (i) the lack of reasonably necessary information being provided to the Certificate

 

     -320-

     

    

 

Administrator or (ii) incomplete, inaccurate or untimely information being provided to the Certificate Administrator. Each Holder
of a Class V Certificate or an RR Interest, by acceptance of its interest in such class of securities, will be deemed to have
agreed to provide the Certificate Administrator with information regarding any sale of such securities, including the price, amount
of proceeds and date of sale. Absent receipt of information regarding any sale of a Class V Certificate or an RR Interest, 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 V Certificates. The CUSIP so published will represent the Rule 144A CUSIP. The Certificate Administrator
shall make reasonable good faith efforts to keep the website accurate and updated to the extent such CUSIP has been received.
Absent the receipt of such CUSIP, the Certificate Administrator will use a reasonable identifier number in lieu of a CUSIP. The
Certificate Administrator shall not be liable for investor reporting delays that result from the receipt of inaccurate or untimely
CUSIP information.

 

Section
4.07     Investor Q&A Forum; Investor Registry; and Rating Agency Q&A Forum and Document
Request Tool. (a) The Certificate Administrator shall make available, only to Privileged Persons, the Investor Q&A
Forum. The “Investor Q&A Forum” shall be a service available on the Certificate Administrator’s
Website, where (i) Certificateholders and beneficial owners of Certificates that are Privileged Persons may submit questions
to (A) the Certificate Administrator relating to the Distribution Date Statement, (B) the Master Servicer or the Special
Servicer, as the case may be, relating to the reports being made available pursuant to Sections 3.13(b) and Section
3.13(d), the Mortgage Loans (excluding any Non-Serviced Mortgage Loan) or the related Mortgaged Properties or (C) the
Operating Advisor relating to the Operating Advisor Annual Report or other reports prepared by the Operating Advisor or
actions by the Special Servicer referenced in any Operating Advisor Annual Report (each an “Inquiry” and
collectively, “Inquiries”), and (ii) Privileged Persons may view Inquiries that have been previously
submitted and answered, together with the answers thereto. Upon receipt of an Inquiry for the Master Servicer, the Special
Servicer, Certificate Administrator or the Operating 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: REAM_InvestorRelations@wellsfargo.com), in each case within a commercially reasonable period of
time following receipt thereof. Following receipt of an Inquiry, the Master Servicer, the Special Servicer, the
Certificate Administrator or the Operating Advisor, as applicable, unless such party determines not to answer such Inquiry as
provided below, shall reply to the Inquiry, which reply of the Master Servicer, the Special Servicer or the Operating
Advisor, as applicable, shall be delivered to the Certificate Administrator by electronic mail. In the case of an Inquiry
relating to a Non-Serviced Mortgage Loan, the Certificate Administrator shall make reasonable efforts to obtain an answer
from the related Non-Serviced Master Servicer or the related Non-Serviced Special Servicer, as applicable; provided
that the Certificate Administrator shall not be responsible for the content of such answer or any delay or failure to obtain
such answer. The Certificate Administrator shall post (within a commercially reasonable period of time following preparation
or receipt of such

 

     -321-

     

    

 

answer, as the case may be) such Inquiry and
the related answer to the Certificate Administrator’s Website. If the Certificate Administrator, the Master Servicer, the
Special Servicer or the Operating Advisor determines, in its respective sole discretion, that (i) any Inquiry is beyond the scope
of the topics described above, (ii) answering any Inquiry would not be in the best interests of the Trust and/or the Certificateholders,
(iii) answering any Inquiry would be in violation of applicable law, the applicable Mortgage Loan documents or this Agreement,
(iv) answering any Inquiry would materially increase the duties of, or result in significant additional cost or expense to, the
Master Servicer, the Special Servicer, the Certificate Administrator or the Operating Advisor, as applicable, (v) answering any
Inquiry would require the disclosure of Privileged Information (subject to the Privileged Information Exception), (vi) that answering
the inquiry would or is reasonably expected to result in a waiver of an attorney-client privilege or the disclosure of attorney
work product or (vii) answering any Inquiry is otherwise, for any reason, not advisable, it shall not be required to answer such
Inquiry and, in the case of the Master Servicer, the Special Servicer or the Operating Advisor, shall promptly notify the Certificate
Administrator of such determination. In addition, no party shall post or otherwise disclose any direct communications with the
Directing Certificateholder or the Risk Retention Consultation Party (in its capacity as Risk Retention Consultation Party) as
part of its response to any Inquiries. The Certificate Administrator shall notify the Person who submitted such Inquiry in the
event that the Inquiry will not be answered. Any notice by the Certificate Administrator to the Person who submitted an Inquiry
that will not be answered shall include the following statement: “Because the Pooling and Servicing Agreement provides that
the Master Servicer, the Special Servicer, the Certificate Administrator and the Operating Advisor shall not answer an Inquiry
if it determines, in its respective sole discretion, that (i) any Inquiry is beyond the scope of the topics described in the Pooling
and Servicing Agreement, (ii) answering any Inquiry would not be in the best interests of the Trust and/or the Certificateholders,
(iii) answering any Inquiry would be in violation of applicable law or the applicable Mortgage Loan documents, (iv) answering
any Inquiry would materially increase the duties of, or result in significant additional costs or expenses to the Trustee, the
Master Servicer, the Special Servicer, the Certificate Administrator or Operating Advisor, as applicable, (v) answering any Inquiry
would require the disclosure of Privileged Information, or (vi) answering any Inquiry is otherwise, for any reason, not advisable,
no inference should or may be drawn from the fact that the Master Servicer, the Special Servicer, the Certificate Administrator
or the Operating Advisor has declined to answer the Inquiry.” Answers posted on the Investor Q&A Forum will be attributable
only to the respondent, and shall not be deemed to be answers from any of the Depositor, the Underwriters or any of their respective
Affiliates. None of the Underwriters, Depositor, the Master Servicer, the Special Servicer, the Certificate Administrator, the
Trustee or the Operating Advisor or any of their respective Affiliates will certify to any of the information posted in the Investor
Q&A Forum and no such party shall have any responsibility or liability for the content of any such information. The Certificate
Administrator shall not be required to post to the Certificate Administrator’s Website any Inquiry or answer thereto that
the Certificate Administrator determines, in its sole discretion, is administrative or ministerial in nature. The Investor Q&A
Forum will not reflect questions, answers and other communications that are not submitted via the Certificate Administrator’s
Website. Notwithstanding the foregoing, the Operating Advisor shall not be required to respond to any Inquiries from Certificateholders
for which its response would require the Operating

 

     -322-

     

    

 

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

 

(b)            The
Certificate Administrator shall make available to any Certificateholder and any Certificate Owner that is a Privileged Person,
the Investor Registry. The “Investor Registry” shall be a voluntary service available on the Certificate Administrator’s
Website, where Certificateholders and Certificate Owners that are Privileged Persons can register and thereafter obtain information
with respect to any other Certificateholder or Certificate Owner that has so registered. Any person registering to use the Investor
Registry shall certify that (a) it is a Certificateholder or a Certificate Owner and a Privileged Person and (b) it grants authorization
to the Certificate Administrator to make its name and contact information available on the Investor Registry for at least forty-five
(45) days from the date of such certification to persons entitled to access to the Investor Registry. Such Person shall then be
asked to enter certain mandatory fields such as the individual’s name, the company name and email address, as well as certain
optional fields such as address, phone, and Class(es) of Certificates owned. If any Certificateholder or Certificate Owner notifies
the Certificate Administrator that it wishes to be removed from the Investor Registry (which notice may not be within forty-five
(45) days of its registration), the Certificate Administrator shall promptly remove it from the Investor Registry. The Certificate
Administrator will not be responsible for verifying or validating any information submitted on the Investor Registry, or for monitoring
or otherwise maintaining the accuracy of any information thereon. The Certificate Administrator may require acceptance of a waiver
and disclaimer for access to the Investor Registry.

 

(c)            The
17g-5 Information Provider shall make available, only to NRSROs, the Rating Agency Q&A Forum and Document Request Tool. The
“Rating Agency Q&A Forum and Document Request Tool” shall be a service available on the 17g-5 Information
Provider’s Website, where NRSROs may (i) submit questions to the Certificate Administrator relating to any Distribution
Date Statements, or submit questions to the Master Servicer or the Special Servicer, as the case may be, relating to the reports
prepared by such parties (each such submission, a “Rating Agency Inquiry”), and (ii) view Rating Agency Inquiries
that have been previously submitted and answered, together with the responses thereto. In addition, NRSROs may use the forum to
submit requests (each such submission also, a “Rating Agency Inquiry”) to the Master Servicer for loan-level
reports and other related information. Upon receipt of a Rating Agency Inquiry for the Master Servicer or the Special Servicer,
the 17g-5 Information Provider shall forward the Rating Agency Inquiry to the appropriate person (in the case of the Master Servicer
to the following: RAInvRequests@wellsfargo.com), in each case within a commercially reasonable period of time following receipt
thereof. Following receipt of a Rating Agency Inquiry from the 17g-5 Information Provider, the Master Servicer or the Special
Servicer, as the case may be, unless it determines not to answer such Rating Agency Inquiry as provided below, shall reply by
email to the Certificate Administrator. The 17g-5 Information Provider shall post (within a commercially reasonable period of
time following receipt of such response) such Rating Agency Inquiry with the related response thereto (or such reports, as applicable)
to the Rating Agency Q&A Forum and Document Request Tool. Any reports posted by the 17g-5 Information Provider in response
to an inquiry may be posted on a separate website or web page accessible by a link on the 17g-5 Information Provider’s Website.
If the Certificate Administrator, the Master Servicer or the Special Servicer determines, in its respective sole discretion, that
(i) answering any Rating Agency Inquiry would be in violation of applicable law,

the Servicing Standard, this Agreement or any
Mortgage Loan documents, (ii) answering any Rating Agency Inquiry would or is reasonably expected to result in a waiver of an
attorney-client privilege with, or the disclosure of attorney work product, or (iii) (A) answering any Rating Agency Inquiry would
materially increase the duties of, or result in significant additional cost or expense to, the Certificate Administrator, the
Master Servicer or the Special Servicer, as applicable, and (B) the Certificate Administrator, the Master Servicer or the Special
Servicer, as applicable, determines in accordance with the Servicing Standard (or in good faith, in the case of the Certificate
Administrator) that the performance of such duties or the payment of such costs and expenses is beyond the scope of its duties
in its capacity as Certificate Administrator, Master Servicer or Special Servicer, as applicable, under this Agreement, it shall
not be required to answer such Rating Agency Inquiry and shall promptly notify the 17g-5 Information Provider by email of such
determination. The 17g-5 Information Provider shall promptly thereafter post the Rating Agency Inquiry with the reason it was
not answered to the Rating Agency Q&A Forum and Document Request Tool. The 17g-5 Information Provider shall not be liable
for the failure by any other such Person to so answer. Questions posted on the Rating Agency Q&A Forum and Document Request
Tool shall not be attributed to the submitting NRSRO. Answers posted on the Rating Agency Q&A Forum and Document Request Tool

in nature. The Rating Agency Q&A Forum and Document Request Tool will not reflect questions, answers and other communications
that are not submitted via the 17g-5 Information Provider’s Website.

 

Section

and the Depositor shall, upon the receipt of each Mortgage Loan Seller’s Diligence File Certification and within 120
days following the Closing Date, deliver to the Certificate Administrator an electronic copy of the Diligence Files for the
Mortgage Loans that have been uploaded by the Mortgage Loan Sellers to the Designated Site. Upon receipt thereof, the
Certificate Administrator shall promptly upload the contents of each Diligence File actually received by it to the Secure
Data Room. Access to the Secure Data Room shall be granted by the Certificate Administrator to (i) the Asset Representations
Reviewer and (ii) any other Person at the direction of the Depositor, in each case, upon the occurrence of an Affirmative
Asset Review Vote and receipt by the Certificate Administrator of a certification substantially in the form of Exhibit
QQ hereto (which shall be sent via email to trustadministrationgroup@wellsfargo.com or submitted electronically via the
Certificate Administrator’s website). In no case whatsoever shall Certificateholders be permitted to access the Secure
Data Room. For the avoidance of doubt, the Certificate Administrator shall be under no obligation to post any documents or
information to the Secure Data Room other than the contents of the Diligence Files initially delivered to it by the
Depositor.

 

(b)            The
Certificate Administrator shall not have any obligation or duty to verify, review, confirm or otherwise determine whether the
type, number or contents of any Diligence File delivered to the Certificate Administrator is accurate, complete, or relates to
the

 

     -324-

     

    

 

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

 

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

Section
5.01     The Certificates. (a) The Certificates will be substantially in the respective forms annexed hereto as Exhibit
A-1 through and including Exhibit A-4, with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Agreement or as may, in the reasonable judgment of the Certificate Registrar,
be necessary, appropriate or convenient to comply, or facilitate compliance, with applicable laws, and may have such letters,
numbers or other marks of identification and such legends or endorsements placed thereon as may be required by law, or as
may, consistently herewith, be determined by the officers executing such Certificates, as evidenced by their execution
thereof. The Class X Certificates will be issuable only in minimum Denominations of authorized initial Notional Amount of not
less than $1,000,000 and in integral multiples of $1.00 in excess thereof.

 

     -325-

     

    

 

The Offered
Certificates (other than the Class X-A Certificates and Class X-B Certificates) will be issuable only in minimum Denominations
of authorized initial Certificate Balance of not less than $10,000, and in integral multiples of $1.00 in excess thereof. The
Non-Registered Certificates (other than any Class X Certificates and other than the Class V and Class R Certificates and the RR
Interest) will be issuable in minimum Denominations of authorized initial Certificate Balance of not less than $100,000, and in
integral multiples of $1.00 in excess thereof. The RR Interest will be issuable in minimum Denominations of authorized initial
Certificate Balance of not less than $1.00, and in integral multiples of $0.01 in excess thereof. If the Original Certificate
Balance or initial Notional Amount, as applicable, of any Class (other than the RR Interest) does not equal an integral multiple
of $1.00, then a single additional Certificate of such Class may be issued in a minimum denomination of authorized initial Certificate
Balance or initial Notional Amount, as applicable, that includes the excess of (i) the Original Certificate Balance or initial
Notional Amount, as applicable, of such Class over (ii) the largest integral multiple of $1.00 that does not exceed such amount.
The Class R and Class V Certificates shall be issued, maintained and transferred in minimum percentage interests of 10% of such
Class R or Class V Certificates and in integral multiples of 1% in excess thereof.

 

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

 

Section
5.02     Form and Registration. No transfer of any Non-Registered Certificate shall be made unless
that transfer is made pursuant to an effective registration statement under the Securities Act, and effective registration or
qualification under applicable state securities laws, or is made in a transaction which does not require such registration or
qualification. If a transfer (other than one by the Depositor to an Affiliate thereof or by the Initial Purchasers to an affiliate
of RREF III Debt AIV, LP) is to be made in reliance upon an exemption from the Securities Act, and under the applicable state
securities laws, then either:

 

(a)            Each
Class of the Non-Registered Certificates sold to institutions that are non-United States Securities Persons in Offshore Transactions
in reliance on Regulation S under the Act shall initially be represented by a temporary book-entry certificate in definitive,
fully registered form without interest coupons, substantially in the applicable form set forth as an exhibit hereto (each a “Temporary
Regulation S Book-Entry Certificate”), which shall be deposited on the Closing Date on behalf of the purchasers of the
Non-Registered Certificates represented thereby with the Certificate Registrar, at its principal trust office, as custodian, for
the Depository, and registered in the name of the Depository or the nominee of the Depository for the account of designated agents
holding on behalf of Euroclear and/or Clearstream. Prior to the expiration of the 40-day period commencing on the later of the
commencement of the offering and the Closing Date (the “Restricted Period”), beneficial interests in each Temporary
Regulation S Book-Entry Certificate may be held only through Euroclear or Clearstream. After the expiration of the Restricted
Period, a beneficial interest in a Temporary Regulation S Book-Entry Certificate may be exchanged for an interest in the related
Regulation S Book-Entry

 

     -326-

     

    

 

Certificate in the applicable form set forth as an exhibit hereto in accordance with the procedures set
forth in Section 5.03(f). During the Restricted Period, distributions due in respect of a beneficial interest in a Temporary
Regulation S Book-Entry Certificate shall only be made upon delivery to the Certificate Registrar by Euroclear or Clearstream,
as applicable, of a Non-U.S. Beneficial Ownership Certification. After the expiration of the Restricted Period, distributions
due in respect of any beneficial interests in a Temporary Regulation S Book-Entry Certificate shall not be made to the holders
of such beneficial interests unless exchange for a beneficial interest in the Regulation S Book-Entry Certificate of the same
Class is improperly withheld or refused. The aggregate Certificate Balance of a Temporary Regulation S Book-Entry Certificate
or a Regulation S Book-Entry Certificate may from time to time be increased or decreased by adjustments made on the records of
the Certificate Registrar, as custodian for the Depository, as hereinafter provided.

 

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

 

(b)            Certificates
of each Class of Non-Registered Certificates (other than any RR Interest during the RR Interest Transfer Restriction Period or
EU Transfer Restriction Period) offered and sold to Qualified Institutional Buyers in reliance on Rule 144A under the Act (“Rule
144A”) shall be represented by Rule 144A Book-Entry Certificates, which shall be deposited with the Certificate Registrar
or an agent of the Certificate Registrar, as custodian for the Depository, and registered in the name of the Depository or a nominee
of the Depository. The aggregate Certificate Balance of a Rule 144A Book-Entry Certificate may from time to time be increased
or decreased by adjustments made on the records of the Certificate Registrar, as custodian for the Depository, as hereinafter
provided.

 

(c)            Certificates
of each Class of Non-Registered Certificates that are initially offered and sold to investors that are Institutional Accredited
Investors that are not Qualified Institutional Buyers (the “Non-Book Entry Certificates”) shall be in the form
of Definitive Certificates, substantially in the applicable form set forth as an exhibit hereto, and shall be registered in the
name of such investors or their nominees by the Certificate Registrar who shall deliver the certificates for such Non-Book Entry
Certificates to the respective beneficial owners or owners. For the avoidance of doubt, the Class R and Class V Certificates shall
only be in the form of Definitive Certificates, and the RR Interest shall be issued in the form of Definitive Certificates at
all times during the RR Interest Transfer Restriction Period and the EU Transfer Restriction Period.

 

     -327-

     

    

 

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

 

(e)            During
the RR Interest Transfer Restriction Period and the EU Transfer Restriction Period, any RR Interest shall only be held as a Definitive
Certificate in the Retained Interest Safekeeping Account by the Certificate Administrator (and each Retaining Party’s respective
interest shall be tracked in the form of an entry in the Certificate Administrator’s trust accounting system under the Retained
Interest Safekeeping Account), for the benefit of the Holder of the related Certificate. The Certificate Administrator shall hold
the RR Interest in safekeeping and shall release the same only upon receipt of written instructions, and in accordance with any
authentication procedures as may be utilized by the Certificate Administrator and in accordance with this Agreement. There shall
be, and hereby is, established by the Certificate Administrator an account which will be designated the “Retained Interest
Safekeeping Account” and into which the RR Interest shall be held and which shall be governed by and subject to this Agreement.
In addition, on and after the date hereof, the Certificate Administrator may establish any number of subaccounts to the Retained
Interest Safekeeping Account for each Retained Party. The RR Interest to be delivered in physical form to the Certificate Administrator
shall be delivered as set forth herein. No amounts distributable to the RR Interest shall be remitted to the Retained Interest
Safekeeping Account, but shall be remitted

 

     -328-

     

    

 

directly
to each Retained Party in accordance with written instructions provided separately by each Retained Party to the Certificate Administrator.
Under no circumstances by virtue of safekeeping the RR Interest shall the Certificate Administrator be obligated to bring legal
action or institute proceedings against any person on behalf of the Retained Parties. During the RR Interest Transfer Restriction
Period and the EU Transfer Restriction Period and for such longer time as the Retaining Parties may request, the Certificate Administrator
shall hold the Definitive Certificate representing the RR Interest at the below location, or any other location; provided
the Certificate Administrator has given notice to each of the Retaining Parties of such new location:

Fargo Bank NA 

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

425

Minneapolis,

The
Certificate Administrator shall make available to each Retaining Party its respective account information as mutually agreed upon
by the Certificate Administrator and each respective Retaining Party, and in accordance with the Certificate Administrator’s
policies and procedures. Any transfer of an RR Interest shall be subject to Section 5.03(g) and Section 5.03(i).
The Certificate Administrator is directed by the Depositor to enter into a safekeeping account agreement to facilitate the initial
settlement and sale of the RR Interest on the Closing Date.

 

Section
5.03     Registration of Transfer and Exchange of Certificates. (a) The Certificate
Administrator shall keep or cause to be kept at the Corporate Trust Office books (the “Certificate
Register”) in which, subject to such reasonable regulations as it may prescribe, the Certificate Administrator
shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided (the
Certificate Administrator, in such capacity, being the “Certificate Registrar”). In such capacities, the
Certificate Administrator shall be responsible for, among other things, (i) maintaining the Certificate Register and a record
of the aggregate holdings of Certificates of each Class of Non-Registered Certificates represented by a Temporary Regulation
S Book-Entry Certificate, a Regulation S Book-Entry Certificate and a Rule 144A Book-Entry Certificate and accepting
Certificates for exchange and registration of transfer, (ii) holding the RR Interest as Definitive Certificates on behalf of
each Holder of such Class and (iii) transmitting to the Depositor, the Master Servicer and the Special Servicer any notices
from the Certificateholders. No fee or service charge shall be imposed by the Certificate Registrar for its services in
respect of any registration of Transfer or exchange of any Certificate (other than Definitive Certificates) referred to in
this Section 5.03.

 

(b)            Subject
to the restrictions on transfer set forth in this Article V, upon surrender for registration of transfer of any Certificate,
the Certificate Registrar 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.

 

(c)            Rule

S Book-Entry Certificate of the same Class, or to transfer its interest in such Rule 144A Book-Entry Certificate to a Person who
is required to take delivery thereof in the form of an interest in the Temporary Regulation S Book-Entry Certificate of the same
Class, such holder may, subject to the rules and procedures of the Depository, exchange or cause the exchange of such interest
for an equivalent beneficial interest in such Temporary Regulation S Book-Entry Certificate. Upon receipt by the Certificate Registrar,
as registrar, at its office designated in Section 5.07, of (1) instructions given in accordance with the Depository’s
procedures from a Depository Participant directing the Certificate Registrar to credit, or cause to be credited, a beneficial
interest in the Temporary Regulation S Book-Entry Certificate in an amount equal to the beneficial interest in the Rule 144A Book-Entry
Certificate to be exchanged, (2) a written order given in accordance with the Depository’s procedures containing information
regarding the Euroclear or Clearstream account to be credited with such increase and the name of such account and (3) a certificate

has been made in compliance with the transfer restrictions applicable to the Book-Entry Certificates and pursuant to and in accordance
with Regulation S, then the Certificate Registrar shall instruct the Depository to reduce, or cause to be reduced, the Certificate
Balance of the Rule 144A Book-Entry Certificate and to increase, or cause to be increased, the Certificate Balance of the Temporary
Regulation S Book-Entry Certificate by the aggregate Certificate Balance of the beneficial interest in the Rule 144A Book-Entry

Regulation S Book-Entry Certificate, without
any registration of such Certificates under the Act (in which case such certificate shall enclose an Opinion of Counsel to such
effect and such other documents as the Certificate Registrar may reasonably require), then the Certificate Registrar shall instruct

from Euroclear or Clearstream, if applicable, and the Depository, directing the Certificate Registrar, as registrar, to credit

Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate to be exchanged, such instructions to contain
information regarding the participant account with the Depository to be credited with such increase, (2) with respect to a transfer
of an interest in the Regulation S Book-Entry Certificate, information regarding the participant account of the Depository to

S Book-Entry Certificate or Regulation S Book-Entry Certificate that is being transferred.

 

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

 

(g)            Non-Book
Entry Certificate to Book-Entry Certificate. If a holder of a Non-Book Entry Certificate (other than (a) a Class R Certificate
or (b) an RR Interest during the RR Interest Transfer Restriction Period or the EU Transfer Restriction Period) wishes at any
time to exchange its interest in such Non-Book Entry Certificate for an interest in a Book-Entry Certificate of the same Class,
or to transfer all or part of such Non-Book Entry Certificate to a Person who is entitled to take delivery thereof in the form
of an interest in a Book-Entry Certificate, such holder may, subject to the rules and procedures of Euroclear or Clearstream,
if applicable, and the Depository, cause the exchange of all or part of such Non-Book Entry Certificate for an equivalent beneficial
interest in the appropriate Book-Entry Certificate of the same Class. Upon receipt by the Certificate Registrar, as registrar,
at its office designated in Section 5.07, of (1) such Non-Book Entry Certificate, duly endorsed as provided herein, (2)
instructions from such holder directing the Certificate Registrar, as registrar, to credit, or cause to be credited, a beneficial
interest in the applicable Book-Entry Certificate equal to the

 

 

     -332-

     

    

 

portion of the Certificate Balance of the Non-Book Entry Certificate
to be exchanged, such instructions to contain information regarding the participant account with the Depository to be credited
with such increase and (3) a certificate in the form of Exhibit M hereto (in the event that the applicable Book-Entry Certificate
is the Temporary Regulation S Book-Entry Certificate), in the form of Exhibit N hereto (in the event that the applicable
Book-Entry Certificate is the Regulation S Book-Entry Certificate) or in the form of Exhibit O hereto (in the event that
the applicable Book-Entry Certificate is the Rule 144A Book-Entry Certificate), then the Certificate Registrar, as registrar,
shall cancel, or cause to be canceled, all or part of such Non-Book Entry Certificate, shall, if applicable, execute, authenticate
and deliver to the transferor a new Non-Book Entry Certificate equal to the aggregate Certificate Balance of the portion retained
by such transferor and shall instruct the Depository to increase, or cause to be increased, such Book-Entry Certificate by the
aggregate Certificate Balance of the portion of the Non-Book Entry Certificate to be exchanged and to credit, or cause to be credited,
to the account of the Person specified in such instructions a beneficial interest in the applicable Book-Entry Certificate equal
to the Certificate Balance of the portion of the Non-Book Entry Certificate so canceled. Upon the written direction of the Depositor
(which may be by email to cts.cmbs.bond.admin@wellsfargo.com) or its Affiliate, the Certificate Registrar shall execute any instrument
as may be reasonably required by the Depository to effect such exchange.

 

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

 

(i)             Transfers
of RR Interest. At all times, if a Transfer of any RR Interest after the Closing Date is to be made, then the
Certificate Registrar shall refuse to register such transfer unless it receives (and, upon receipt, may conclusively rely
upon) (i) a certification from such Certificateholder’s prospective Transferee substantially in the form attached
hereto as Exhibit D-3, which such certification must be countersigned by the Retaining Sponsor with a medallion stamp
guarantee of the Retaining Sponsor and (ii) a certification from the Certificateholder desiring to effect such transfer
substantially in the form attached hereto as Exhibit D-4, which such certification must be countersigned by the
Retaining Sponsor with a medallion stamp guarantee of the Retaining Sponsor. Upon receipt of the foregoing certifications,
the Certificate Registrar shall, subject to Section 5.02(e) and Section 5.03(a), reflect such RR Interest in
the name of the prospective Transferee. For the avoidance of doubt, in no event shall an RR Interest be held as a Book-Entry
Certificate during the RR Interest Transfer Restriction Period or the EU Transfer Restriction Period.

 

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

 

     -333-

     

    

 

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

 

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

 

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

 

(n)           With
respect to the ERISA Restricted Certificates, no sale, transfer, pledge or other disposition (other than any initial transfer
to the Initial Purchasers or with respect to the RR Interest, the Mortgage Loan Sellers) of any such Certificate shall be made
unless the Trustee and Certificate Administrator shall have received either (i) a representation letter from the proposed purchaser
or transferee of such Certificate substantially in the form of Exhibit F-1 attached hereto, to the effect that such proposed
purchaser or transferee is not and will not be (A) an employee benefit plan subject to the fiduciary responsibility provisions
of ERISA or a plan subject to Section 4975 of the Code, or a governmental plan (as defined in Section 3(32) of ERISA), a church
plan (as defined in Section 3(33) of ERISA) for which no election has been made under Section 410(d) of the Code or any other
plan subject to any federal, state or local law (“Similar Law”) which is, to a material extent, similar to
the foregoing provisions of ERISA or the Code (each, a “Plan”) or (B) a person acting on behalf of or using
the assets of any such Plan (including an entity whose underlying assets include Plan assets within the meaning of Department
of Labor Regulation § 2510.3-101, as modified by Section 3(42) of ERISA), other than an insurance company using the assets
of its general account under circumstances whereby the purchase and holding of such Certificates by such insurance company would
be exempt from the prohibited transaction provisions of ERISA and the Code under Sections I and III of Prohibited Transaction
Class Exemption 95-60 (or, in the case of a Plan subject to Similar Law, would not result in a non-exempt violation of Similar
Law) or (ii) if such Certificate is presented for registration in the name of a purchaser or transferee that is any of the foregoing,
an Opinion of Counsel in form and substance satisfactory to the Trustee, the Certificate Administrator and the Depositor to the
effect that the acquisition and holding of such Certificate by such purchaser or transferee will not constitute or result in a
non-exempt “prohibited transaction” within the meaning of ERISA, Section 4975 of the Code or a non-exempt violation
of any Similar Law, and will not subject the Trustee, the Certificate Administrator, the Certificate Registrar, the Master Servicer,
the Special Servicer, any Sub-Servicer, the Initial Purchasers, the Underwriters, the Operating Advisor, the Asset Representations
Reviewer or the Depositor to any obligation or liability (including obligations or liabilities under ERISA, Section 4975 of the
Code or any such 

 

     -334-

     

    

 

Similar Law) in addition to those set forth in the Agreement. The Trustee and Certificate Administrator shall
not register the sale, transfer, pledge or other disposition of any ERISA Restricted Certificate unless the Trustee and Certificate
Administrator have received either the representation letter described in clause (i) above or the Opinion of Counsel described
in clause (ii) above. The costs of any of the foregoing representation letters or Opinions of Counsel shall not be borne
by any of the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Initial Purchasers,
the Underwriters, the Operating Advisor, the Certificate Registrar, the Asset Representations Reviewer or the Trust. Each Certificate
Owner of an ERISA Restricted Certificate shall be deemed to represent that it is not and will not become a Person specified in
clauses (i)(A) or (i)(B) above. Any transfer, sale, pledge or other disposition of any ERISA Restricted Certificates
that would constitute or result in a prohibited transaction under ERISA, Section 4975 of the Code or any Similar Law, or would
otherwise violate the provisions of this Section 5.03(n) shall be deemed absolutely null and void ab initio, to
the extent permitted under applicable law.

 

(o)           No
Class R or Class V Certificate may be purchased by or transferred to any prospective purchaser or transferee that is or will be
a Plan, or any person acting on behalf of a Plan or using the assets of a Plan (including an entity whose underlying assets include
Plan within the meaning of Department of Labor Regulation § 2510.3-101, as modified by Section 3(42) of ERISA) to purchase
such Class R or Class V Certificate. Each prospective transferee of a Class R or Class V 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 and will not become 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.

 

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

 

     -335-

     

    

 

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

 

(iii)           Notwithstanding
the delivery of a Transferee Affidavit by a proposed transferee under clause (ii) above, if a Responsible Officer of the
Certificate Registrar has actual knowledge that the proposed transferee is not a Permitted Transferee, no Transfer to such proposed
transferee shall be effected and such proposed Transfer shall not be registered on the Certificate Register; provided,
however, that the Certificate Registrar shall not be required to conduct any independent investigation to determine whether
a proposed transferee is a Permitted Transferee. Upon notice to the Certificate Registrar that there has occurred a Transfer to
any Person that is a Disqualified Organization or an agent thereof (including a broker, nominee or middleman) in contravention
of the foregoing restrictions, and in any event not later than sixty (60) days after a request for information from the transferor
of such Residual Ownership Interest or such agent, the Certificate Registrar agrees to furnish to the Internal Revenue Service
and the transferor of such Residual Ownership Interest or such agent such information necessary to the application of Section
860E(e) of the Code as may be required by the Code, including, but not limited to, the present value of the total anticipated
excess inclusions with respect to such Class R Certificate (or portion thereof) for periods after such Transfer. At the election
of the Certificate Registrar, the Certificate Registrar may charge a reasonable fee for computing and furnishing such information
to the transferor or to such agent referred to above; provided, however, that such Persons shall in no event be
excused from furnishing such information.

 

     -336-

     

    

 

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

 

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

 

Section
5.04     Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate
is surrendered to the Certificate Registrar, or the Certificate Registrar receives evidence to its satisfaction of the
destruction, loss or theft of any Certificate and (b) there is delivered to the Certificate Registrar such security or
indemnity as may be required by it to save it harmless, then, in the absence of actual notice to the Certificate Registrar
that such Certificate has been acquired by a bona fide purchaser, the Certificate Registrar shall execute, authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and interest in the Trust. In connection with the issuance of any new Certificate under this Section 5.04, the
Certificate Registrar may require the payment of a sum sufficient to cover any expenses (including the fees and expenses of
the Certificate Registrar) connected therewith. Any replacement Certificate issued pursuant to this Section 5.04 shall
constitute complete and indefeasible evidence of ownership in the Trust, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time.

 

Section
5.05     Persons Deemed Owners. The Master Servicer, the Special Servicer, the Certificate Administrator,
the Trustee and the Certificate Registrar, and any agent of any of them, 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 this Agreement and for all
other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee,
the Certificate Registrar or any agent of any of them shall be affected by any notice to the contrary; provided, however,
that to the extent that a party to this Agreement responsible for distributing any report, statement or other information required
to be distributed to Certificateholders has been provided an Investor Certification, such party to this Agreement shall distribute
such report, statement or other information to such beneficial owner (or prospective transferee).

 

Section
5.06     Access to List of Certificateholders’ Names and Addresses; Special
Notices. (a) The Certificate Registrar shall maintain in as current form as is reasonably practicable the most recent
list available to it of the names and addresses of the Certificateholders. If any Certificateholder that has provided an
Investor Certification (i) requests in writing from the Certificate Registrar a list of the names and addresses of

Certificateholders, (ii) states that such Certificateholder
desires to communicate with other Certificateholders with respect to its rights under this Agreement or under the Certificates
and (iii) provides a copy of the communication which Certificateholder proposes to transmit, then the Certificate Registrar shall,
within ten (10) Business Days after the receipt of such request, furnish such Certificateholder (at such Certificateholder’s
sole cost and expense) a current list of the Certificateholders. In addition, upon written request to the Certificate Administrator
of any Certificateholder or Certificate Owner (if applicable) that has provided an Investor Certification, the Certificate Administrator
shall promptly notify such Certificateholder or Certificate Owner of the identity of the then-current Directing Certificateholder.
Every Certificateholder, by receiving and holding a Certificate, agrees that the Certificate Registrar shall not be held accountable
by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source
from which information was derived. The Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the
Operating Advisor and the Depositor shall be entitled to a list of the names and addresses of Certificateholders from time to
time upon request therefor.

 

(b)           (i)The
Certificate Administrator shall include in any Form 10-D any written request received in accordance with Section 11.04(a)
prior to the Distribution Date to which the Form 10-D relates (and on or after the Distribution Date preceding such Distribution
Date) from a Certificateholder or Certificate Owner to communicate with other Certificateholders or Certificate Owners related
to Certificateholders or Certificate Owners exercising their rights under the terms of this Agreement. Any Form 10-D containing
such disclosure (a “Special Notice”) regarding the request to communicate shall include the following and no
more than the following (a) the name of the Certificateholder or Certificate Owner making the request, (b) the date the request
was received, (c) a statement to the effect that the Certificate Administrator has received such request, stating that such Certificateholder
or Certificate Owner is interested in communicating with other Certificateholders or Certificate Owners with regard to the possible

Owners in the securitization transaction to which this report on Form 10-D relates (the “Securitization”).

Certificateholder or Certificate Owner is the holder of record with respect to any Certificate, the Certificate Administrator
shall not require any further verification or (ii) if the Certificateholder or Certificate Owner is not the holder of record with
respect to any Certificate, the Certificate Administrator shall require no more than (x) a written certification from such Certificateholder

to be maintained an office or offices or agency or agencies where Certificates may be surrendered for registration of

Section
5.10     Voting Procedures. With respect to any matters submitted to Certificateholders for a

and directly with registered Holders by mail with respect to Definitive Certificates. In each case, such vote shall be
administered in accordance with the following procedures, unless different procedures are otherwise described herein with
respect to a specific vote:

 

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

 

(b)            In
connection with any vote administered pursuant to this Agreement, voting Holders shall be required to certify their holdings in
the manner set forth on the ballot, unless a specific manner is otherwise provided herein. Holders may only vote in accordance
with their Voting Rights. Voting Rights with respect to any outstanding Class of Certificates shall be calculated by the Certificate
Administrator in accordance with the definition of Voting Rights as of the record date for the vote. Only Classes with an outstanding

vote, the vote may be changed or retracted on or before the vote deadline. Any changes or retractions shall be communicated by
the Certificateholder to the Certificate Administrator in writing on a ballot. After the vote deadline has passed, votes may not

shall be bound by all votes of Holders initiated or conducted prior to its acquisition of such Certificate.

 

(c)            The

shall use its reasonable efforts to resolve any illegible or incomplete ballots received prior to the voting deadline. Illegible
or incomplete ballots that are received on the voting deadline or that cannot be resolved by the voting deadline shall not be
counted. Promptly after the votes are tabulated, the Certificate Administrator shall prepare a notice announcing the results of
the vote. Such notice shall include the percentage of Voting Rights in favor of the proposition, the percentage against the proposition
and the percentage abstaining. In addition, the notice will announce whether the proposition has been adopted by Certificateholders.
The notice shall be distributed in accordance

 

     -340-

     

    

 

with the methods described in Section 5.10(a) below. The Certificate Administrator
shall also include such notice on the Form 10-D prepared in connection with the distribution period that corresponds with the
date such notice is distributed. All vote tabulations shall be final and the Certificate Administrator shall not, absent manifest
error, re-tabulate the votes or conduct a new vote for the same proposition.

 

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

 

(e)            If
any party to this Agreement believes a vote of Certificateholders is needed for some matter related to the administration of the
Trust that is not specifically contemplated herein, such party may request the Certificate Administrator to conduct a vote and
the Certificate Administrator will conduct the requested vote in accordance with these procedures. Unless specifically provided
herein, all such votes require a majority of Certificateholders to carry a proposition.

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

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

 

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

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

 

     -347-

     

    

 

Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset
Representations Reviewer (such Person, in the case of the Master Servicer or the Special Servicer, in each of the foregoing cases,
the “Surviving Entity”), as the case may be, hereunder, without the execution or filing of any paper (other
than an assumption agreement wherein the successor shall agree to perform the obligations of and serve as the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer, as the case may be, in accordance
with the terms of this Agreement) or any further act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that with respect to such merger, consolidation or succession, Rating Agency
Confirmation is received from each Rating Agency with respect to the Classes of Certificates and, with respect to any class of
Serviced Companion Loan Securities, a confirmation is received from each applicable rating agency that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates as described in Section 3.25); provided, further, that if the Master Servicer, the Special Servicer
or the Operating Advisor enters into a merger and the Master Servicer, the Special Servicer or the Operating Advisor, as applicable,
is the surviving entity under applicable law, the Master Servicer, the Special Servicer or the Operating Advisor, as applicable,
shall not, as a result of the merger, be required to provide a Rating Agency Confirmation with respect to ratings of the Classes
of Certificates or, with respect to any class of Serviced Companion Loan Securities, a confirmation of the rating agencies that
such action will not result in the downgrade, withdrawal or qualification of its then-current ratings; provided, further,
that for so long as the Trust, and, with respect to any Serviced Companion Loan included as part of the trust in a related Other
Securitization, is subject to the reporting requirements of the Exchange Act, if the Master Servicer, the Special Servicer or
the Operating Advisor notifies the Depositor in writing (a “Merger Notice”) of any such merger, consolidation,
conversion or other change in form, and the Depositor or the depositor in such Other Securitization, as the case may be, notifies
the Master Servicer, the Special Servicer or the Operating Advisor, as applicable, in writing that the Depositor or the depositor
in such Other Securitization, as the case may be, has discovered that such successor entity has not complied with its Exchange
Act reporting obligations under any other commercial mortgage loan securitization (and specifically identifying the instance of
noncompliance), then it shall be an additional condition to such succession that the Depositor or the depositor in such Other
Securitization, as the case may be, shall have consented (which consent shall not be unreasonably withheld or delayed) to such
successor entity. Notwithstanding the foregoing, no Master Servicer, Special Servicer or Operating Advisor may remain the Master
Servicer, the Special Servicer or Operating Advisor, as applicable, under this Agreement after (x) being merged or consolidated
with or into any Person that is a Prohibited Party, or (y) transferring all or substantially all of its assets to any Person if
such Person is a Prohibited Party, except to the extent (i) the Master Servicer, the Special Servicer or Operating Advisor, as
applicable, is the surviving entity of such merger, consolidation or transfer and has been and continues to be in compliance with
its Regulation AB reporting obligations hereunder or (ii) the Depositor consents to such merger, consolidation or transfer, which
consent shall not be unreasonably withheld. If, within sixty (60) days following the date of delivery of the Merger Notice to
the Depositor or the depositor in such Other Securitization, as the case may be, the Depositor or depositor in such Other Securitization,
as the case may be, shall have failed to notify the Master Servicer or the Special Servicer, as applicable,

 

     -348-

     

    

 

in writing of the
Depositor’s determination, or depositor’s determination, in the case of an Other Securitization, to grant or withhold
such consent, such failure shall be deemed to constitute a grant of such consent. If the conditions to the provisions in the second
preceding sentence are not met, the Trustee may terminate, and if the conditions set forth in the third proviso of the third preceding
sentence are not met the Trustee shall terminate, the applicable Surviving Entity’s servicing of the Mortgage Loans pursuant
hereto, such termination to be effected in the manner set forth in Section 7.01.

 

(i)             The
Asset Representations Reviewer shall keep in full effect its existence and rights as an entity under the laws of the jurisdiction
of its organization, and shall be in compliance with the laws of all jurisdictions to the extent necessary to perform its duties
under this Agreement.

 

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

 

Section
6.04     Limitation on Liability of the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer and Others. (a) None of the Depositor, the Master Servicer
(including in its capacity as Companion Paying Agent, if applicable), the Special Servicer, the Operating Advisor, the Asset
Representations Reviewer or any of the partners, directors, officers, shareholders, members, managers, employees or agents of
any of the foregoing shall be under any liability to the Trust, the Certificateholders or the Companion Holders for any
action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in
judgment; provided, however, that this provision shall not protect the Depositor, the Master Servicer
(including in its capacity as Companion Paying Agent, if applicable), the Special Servicer, the Operating Advisor, the Asset
Representations Reviewer or any such Person against any breach of warranties or representations made herein or any liability
which would otherwise be imposed by reason of willful misconduct, bad faith or negligence in the performance of such
party’s duties or by reason of negligent disregard of such party’s obligations and duties hereunder. The
Depositor, the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer and any partner, director, officer, shareholder, member, manager,
employee or agent of the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent, if applicable),
the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, and any of the partners, directors,
officers, shareholders, members, managers, employees or agents of any of the foregoing may rely on any document of any kind
which, prima facie, is properly executed and submitted by any Person respecting any matters arising hereunder. The
Depositor, the Master Servicer (including in its capacity as Companion Paying Agent, if

 

     -349-

     

    

 

applicable), the Special Servicer, the Asset Representations Reviewer and the Operating Advisor and any partner, director,
officer, shareholder, member, manager, employee or agent of any of the foregoing shall be indemnified and held harmless by the
Trust against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and
any other costs, liabilities, fees and expenses incurred in connection with any actual or threatened legal or administrative action
(whether in equity or at law) or claim relating to this Agreement, the Mortgage Loans, the Companion Loans or the Certificates,
other than any loss, liability or expense: (i) specifically required to be borne thereby pursuant to the terms hereof; (ii) incurred
in connection with any breach of a representation or warranty made by it herein; (iii) incurred by reason of bad faith, willful
misconduct or negligence in the performance of its obligations or duties hereunder, or by reason of negligent disregard of such
obligations or duties; or (iv) in the case of the Depositor and any of its partners, directors, officers, shareholders, members,
managers, employees and agents, incurred in connection with any violation by any of them of any state or federal securities law.
In addition, absent actual fraud (as determined by a final non-appealable court order), neither the Trustee nor the Certificate
Administrator (including in its capacity as Custodian, Certificate Registrar and 17g-5 Information Provider) shall be liable for
special, punitive, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits),
even if the Trustee or the Certificate Administrator has been advised of the likelihood of such loss or damage and regardless
of the form of action. Each of the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special
Servicer, the Asset Representations Reviewer and the Operating Advisor conclusively may rely on, and shall be protected in acting
or refraining from acting upon, any resolution, officer’s certificate, certificate of auditors or any other certificate,
statement, instrument, opinion, report, notice, request, consent, order, financial statement, agreement, appraisal, bond or other
document (in electronic or paper format) as contemplated by and in accordance with this Agreement and reasonably believed or in
good faith believed by the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special Servicer,
the Asset Representations Reviewer or the Operating Advisor to be genuine and to have been signed or presented by the proper party
or parties and each of them may consult with counsel, in which case any written advice of counsel or Opinion of Counsel shall
be full and complete authorization and protection with respect to any action taken or suffered or omitted by it hereunder in good
faith and in accordance with such advice or Opinion of Counsel.

 

(b)           None
of the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special Servicer,
the Operating Advisor and the Asset Representations Reviewer shall be under any obligation to appear in, prosecute or defend any
legal or administrative action (whether in equity or at law), proceeding, hearing or examination that is not incidental to its
respective duties under this Agreement or which in its opinion may involve it in any expense or liability not recoverable from
the Trust; provided, however, that each of the Depositor, the Master Servicer, the Special Servicer, the Operating
Advisor or the Asset Representations Reviewer may in its discretion undertake any such action, proceeding, hearing or examination
that it may deem necessary or desirable in respect to this Agreement and the rights and duties of the parties hereto and the interests
of the Certificateholders (and, in the case of any Serviced Whole Loan, the rights of the Certificateholders and the holders of
a Serviced Companion Loan (as a collective whole) taking into account the subordinate or pari passu nature of such Serviced
Companion Loan); provided, however, that if a Serviced Whole Loan and/or the holder of any related Companion Loan
are

 

     -350-

     

    

 

involved, such expenses, costs and liabilities will be payable out of funds related to the applicable Serviced Whole Loan
in accordance with the related Intercreditor Agreement and will also be payable out of the other funds in the Collection Account
if amounts on deposit with respect to such Serviced Whole Loan are insufficient therefor. If any such expenses, costs or liabilities
relate to a Mortgage Loan or Companion Loan, then any subsequent recovery on that Mortgage Loan or Companion Loan, as applicable,
will be used to reimburse the Trust for any amounts advanced for the payment of such expenses, costs or liabilities. In such event,
the legal expenses and costs of such action, proceeding, hearing or examination and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust, and the Depositor, the Master Servicer (including in its capacity as Companion Paying
Agent, if applicable), the Special Servicer, the Asset Representations Reviewer and the Operating Advisor shall be entitled to
be reimbursed therefor out of amounts attributable to the Mortgage Loans or the Companion Loan on deposit in the Collection Account
(including, without duplication, any subaccount thereof), as provided by Section 3.05(a)(xii).

 

(c)            Each
of the Master Servicer and the Special Servicer, as applicable, agrees to indemnify the Depositor, the Trustee, the related Serviced
Companion Noteholder, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer, the Master Servicer
(including in its capacity as Companion Paying Agent, if applicable) (in the case of the Special Servicer), the Special Servicer
(in the case of the Master Servicer) and the Trust and any partner, director, officer, shareholder, member, manager, employee
or agent thereof, and hold them harmless, from and against any and all claims, losses, penalties, fines, forfeitures, reasonable
legal fees and related costs, judgments, and any other costs, liabilities, fees and expenses that any of them may sustain arising
from or as a result of any willful misconduct, bad faith or negligence of the Master Servicer or the Special Servicer, as the
case may be, in the performance of its obligations and duties under this Agreement or by reason of negligent disregard by the
Master Servicer or the Special Servicer, as the case may be, of its duties and obligations hereunder or by reason of breach of
any representations or warranties made herein by the Master Servicer or the Special Servicer, as applicable. The Trustee, the
Certificate Administrator, the Depositor, the Asset Representations Reviewer or the Operating Advisor, as the case may be, shall
immediately notify the Master Servicer or the Special Servicer, as applicable, if a claim is made by a third party with respect
to this Agreement or the Mortgage Loans entitling the Trust to indemnification hereunder, whereupon the Master Servicer or the
Special Servicer, as the case may be, shall assume the defense of such claim (with counsel reasonably satisfactory to the Trustee,
the Certificate Administrator or the Depositor) and pay all expenses in connection therewith, including counsel fees, and promptly
pay, discharge and satisfy any judgment or decree which may be entered against it or them in respect of such claim. Any failure
to so notify the Master Servicer or the Special Servicer, as the case may be, shall not affect any rights any of the foregoing
Persons may have to indemnification under this Agreement or otherwise, unless the Master Servicer’s or the Special Servicer’s,
as the case may be, defense of such claim is materially prejudiced thereby.

 

Each
of the Master Servicer and the Special Servicer shall indemnify and hold harmless the Depositor from and against any claims, losses,
damages, penalties, fines, forfeitures, legal fees and expenses and related costs, judgments and other costs and expenses incurred
by the Depositor or its Affiliates that arise out of or are based upon, severally and not jointly (i) a breach by the Master Servicer
or Special Servicer, as applicable, of any obligation it

 

     -351-

     

    

 

has to deliver information to the 17g-5 Information Provider as set forth
in this Agreement, including Section 3.07(a), Section 3.08, Section 3.09(e), Section 3.12, Section

of the Trustee and the Certificate Administrator (including in its role as Custodian), respectively agrees to indemnify the
Depositor, the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special Servicer,
the Certificate Administrator (in the case of the Trustee), the Trustee (in the case of the Certificate Administrator), the
Operating Advisor, the Asset Representations Reviewer and the Trust and any partner, director, officer, shareholder, member,

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

 

(e)            The
Depositor agrees to indemnify the Master Servicer (including in its capacity as Companion Paying Agent, if applicable), the Special
Servicer, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer and the Trust

other costs, liabilities, fees and expenses that any of them may sustain arising from or as a result of any willful misconduct,
bad faith or negligence of the Depositor, in the performance of its obligations and duties under this Agreement or by reason of
negligent disregard by the Depositor of its duties and obligations hereunder or by reason of breach of any representations or
warranties made herein; provided that such indemnity shall not cover indirect or consequential damages. The Master Servicer,
the Special Servicer, the Trustee, the Certificate Administrator, the Asset Representations Reviewer or the Operating Advisor,
as the case may be, shall immediately notify the Depositor if a claim is made by a third party with respect to this Agreement,
whereupon the Depositor shall assume the defense of such claim (with counsel reasonably satisfactory to the

 

     -352-

     

    

 

Master Servicer (including
in its capacity as Companion Paying Agent, if applicable) or the Special Servicer, as the case may be) and pay all expenses in
connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered
against it or them in respect of such claim. Any failure to so notify the Depositor shall not affect any rights any of the foregoing
Persons may have to indemnification under this Agreement or otherwise, unless the Depositor’s defense of such claim is materially
prejudiced thereby.

 

(f)            The
Operating Advisor agrees to indemnify the Master Servicer (including in its capacity as Companion Paying Agent, if applicable),
the Special Servicer, the Trustee, the Certificate Administrator, the Depositor, the Asset Representations Reviewer and the Trust
and any partner, director, officer, shareholder, member, manager, employee or agent thereof, and hold them harmless, from and
against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any
other costs, liabilities, fees and expenses that any of them may sustain arising from or as a result of any willful misconduct,
bad faith or negligence of the Operating Advisor, in the performance of its obligations and duties under this Agreement or by
reason of negligent disregard by the Operating Advisor of its duties and obligations hereunder or by reason of breach of any representations
or warranties made herein; provided that such indemnity shall not cover indirect or consequential damages. The Master Servicer,
the Special Servicer, the Trustee, the Certificate Administrator, the Asset Representations Reviewer or the Depositor, as the
case may be, shall immediately notify the Operating Advisor if a claim is made by a third party with respect to this Agreement
or the Mortgage Loans entitling the Trust to indemnification hereunder, whereupon the Operating Advisor shall assume the defense
of such claim (with counsel reasonably satisfactory to the Master Servicer (including in its capacity as Companion Paying Agent),
the Special Servicer, the Trustee, the Certificate Administrator, the Asset Representations Reviewer or the Depositor) and pay
all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which
may be entered against it or them in respect of such claim. Any failure to so notify the Operating Advisor shall not affect any
rights any of the foregoing Persons may have to indemnification under this Agreement or otherwise, unless the Operating Advisor’s
defense of such claim is materially prejudiced thereby.

 

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

 

(h)           The
Asset Representations Reviewer agrees to indemnify the Master Servicer (including in its capacity as Companion Paying Agent, if
applicable), the Special Servicer, the Trustee, the Certificate Administrator, the Depositor, the Operating Advisor and the Trust
and any partner, director, officer, shareholder, member, manager, employee or agent thereof, and hold them harmless, from and
against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any
other costs, liabilities,

 

     -353-

     

    

 

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

 

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

 

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

 

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

 

     -354-

     

    

 

Servicer and the Special Servicer will be entitled to rely on advice of counsel,
the cost of which will be reimbursed as an additional expense of the Trust).

 

Section
6.05     Depositor, Master Servicer and Special Servicer Not to Resign. Subject to the
provisions of Section 6.03, neither the Master Servicer nor the Special Servicer shall resign from their respective
obligations and duties hereby imposed on each of them except upon (a) determination that such party’s duties hereunder
are no longer permissible under applicable law or (b) in the case of the Master Servicer or the Special Servicer, upon the
appointment of, and the acceptance of such appointment by, a successor (which may be appointed by the resigning Master
Servicer or Special Servicer, as applicable), and receipt by the Certificate Administrator and the Trustee of Rating Agency
Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will not result in
the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if
any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating
Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25). Any such
determination permitting the resignation of the Master Servicer or the Special Servicer pursuant to clause (a) above
shall be evidenced by an Opinion of Counsel (at the expense of the resigning party) to such effect delivered to the Trustee
and (prior to the occurrence and continuance of a Consultation Termination Event) the Directing Certificateholder. Unless
applicable law requires the resignation of the Master Servicer or the Special Servicer (as the case may be) to be effective
immediately, and the Opinion of Counsel delivered pursuant to the prior sentence so states, no such resignation by the Master
Servicer or the Special Servicer under clause (a) above shall become effective until the Trustee or a successor master
servicer or special servicer, as applicable, shall have assumed the Master Servicer’s or the Special
Servicer’s, as applicable, responsibilities and obligations in accordance with Section 7.02 and no such
resignation by the Master Servicer or the Special Servicer shall become effective until the Certificate Administrator shall
have filed any required Form 8-K pursuant to Section 11.07 and any other Form 8-K filings have been completed with
respect to any related Companion Loan. Upon any termination (as described in Section 7.01(c)) or resignation of the
Master Servicer or the Special Servicer, pursuant to this Section 6.05, the Master Servicer or the Special Servicer,
as applicable, shall have the right and opportunity to appoint any successor master servicer or special servicer with respect
to this Section 6.05; provided that, such successor master servicer or special servicer shall not be the Asset
Representations Reviewer, the Operating Advisor or one of their respective Affiliates and (prior to the occurrence and
continuance of a Control Termination Event) such successor special servicer is approved by the Directing Certificateholder,
such approval not to be unreasonably withheld. The resigning party shall pay all reasonable out-of-pocket costs and expenses
(including reasonable out-of-pocket costs and expenses incurred by the Trustee and the Certificate Administrator) associated
with a transfer of its duties pursuant to this Section 6.05. Except as provided in Section 7.01(c), in no event
shall the Master Servicer or the Special Servicer have the right to appoint any successor master servicer or special servicer
if the Master Servicer or Special Servicer, as applicable, is terminated or removed pursuant to Section
7.01.

 

Section
6.06     Rights of the Depositor in Respect of the Master Servicer and the Special Servicer.
The Depositor may, but is not obligated to, enforce the obligations of the Master Servicer and the Special Servicer hereunder
and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of the Master Servicer
and the Special

 

     -355-

     

    

 

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

 

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

 

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

 

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

(i)            any

3.16(a)(iii) of this Agreement, in each case, for less than the applicable Purchase Price;

 

(v)           any

Passu Companion Loan Holder related to a Mortgage Loan or Whole Loan, or any action to enforce rights (or decision not to enforce
rights) with respect thereto; provided, however, that any such modification or amendment that would adversely impact
the Master Servicer shall additionally require the consent of the Master Servicer as a condition to its effectiveness;

 

(xiii)        agreeing
to any modification, waiver, consent or amendment of the related Mortgage Loan or Serviced Whole Loan in connection with a defeasance

required under the Mortgage Loan or Serviced Whole Loan documents such that defeasance collateral other than direct, non-callable
obligations of the United States would be permitted or (B) a modification that would permit a principal prepayment instead of

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

 

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

 

provided
that with respect to any Non-Specially Serviced Loan, if the Special Servicer determines, with respect to clause (xii) above,
that a modification, amendment or waiver is administrative in nature, including a note splitting amendment, the Special Servicer
shall provide written notice of such determination to the Master Servicer, in which case, the Master Servicer will process such
decision and such decision will be deemed to be a Master Servicer Decision

 

     -358-

     

    

 

not a Major Decision (provided, further,
that the Special Servicer shall make any such determination and provide any such notice within two (2) business days of its receipt
of a request related to any such decision); provided, however, that, in the event that the Special Servicer or the
Master Servicer, as the case may be, determines that immediate action, with respect to the foregoing matters, or any other matter
requiring consent of the Directing Certificateholder prior to the occurrence and continuance of a Control Termination Event in
this Agreement (or any matter requiring consultation with the Directing Certificateholder, the Risk Retention Consultation Party
or the Operating Advisor), is necessary to protect the interests of the Certificateholders (or, with respect to any Serviced Whole
Loan, the interest of the Certificateholders and the holders of any related Serviced Companion Loan) (as a collective whole (taking
into account the subordinate or pari passu nature of any Companion Loans)), the Special Servicer or the Master Servicer,
as the case may be, may take any such action without waiting for the Directing Certificateholder’s response (or without
waiting to consult with the Directing Certificateholder, the Risk Retention Consultation Party or the Operating Advisor, as the
case may be); provided that the Special Servicer or the Master Servicer, as the case may be, provides the Directing Certificateholder
(or the Operating Advisor, if applicable) and the Risk Retention Consultation Party (if applicable) with prompt written notice
following such action including a reasonably detailed explanation of the basis therefor. None of the Master Servicers or the Special
Servicers is required to obtain the consent of the Directing Certificateholder for any of the foregoing actions or any other matter
requiring consent of the Directing Certificateholder after the occurrence and during the continuance of a Control Termination
Event; provided, however, that, after the occurrence and during the continuance of a Control Termination Event,
the Special Servicer shall consult with the Directing Certificateholder (only prior to the occurrence and continuance of a Consultation
Termination Event) in connection with any Major Decision not relating to an Excluded Loan with respect to the Directing Certificateholder
(and any other actions which otherwise require consultation with the Directing Certificateholder prior to the occurrence and continuance
of a Consultation Termination Event hereunder) and consider alternative actions recommended by the Directing Certificateholder
in respect thereof. Additionally, upon request, the Special Servicer shall consult with the Risk Retention Consultation Party
on a non-binding basis ((i) prior to the occurrence and continuance of a Consultation Termination Event, only with respect to
a Specially Serviced Loan and (ii) after the occurrence and during the continuance of a Consultation Termination Event, with respect
to any Mortgage Loan) in connection with any Major Decision not relating to an Excluded Loan with respect to the Risk Retention
Consultation Party and consider alternative actions recommended by the Risk Retention Consultation Party, in respect thereof.
In the event the Special Servicer receives no response from the Directing Certificateholder or the Risk Retention Consultation
Party within 10 Business Days following its written request for input on any required consultation, the Special Servicer shall
not be obligated to consult with the Directing Certificateholder or the Risk Retention Consultation Party, as applicable, on the
specific matter; provided, however, that the failure of the Directing Certificateholder or the Risk Retention
Consultation Party to respond shall not relieve the Special Servicer from consulting with the Directing Certificateholder or the
Risk Retention Consultation Party, as applicable, on any future matters with respect to the applicable Mortgage Loan (other than
a Non-Serviced Mortgage Loan or an Excluded Loan with respect to such party) or Serviced Whole Loan. In addition, after a Control
Termination Event, the Special Servicer will also be required to consult with the Operating Advisor in connection with any proposed
Major Decision (and any other

 

     -359-

     

    

 

actions
which otherwise require consultation with the Operating Advisor after the occurrence and during the continuance of a Control Termination
Event hereunder) and consider alternative actions recommended by the Operating Advisor, in respect thereof, provided that
such consultation is on a non-binding basis. In the event that the Special Servicer receives no response from the Operating Advisor
within 10 Business Days following the later of (i) its written request for input on any required consultation and (ii) delivery
of all such additional information reasonably requested by the Operating Advisor related to the subject matter of such consultation,
the Special Servicer shall not be obligated to consult with the Operating Advisor on the specific matter; provided, however,
that the failure of the Operating Advisor to respond on any specific matters shall not relieve the Special Servicer from its obligation
to consult with the Operating Advisor on any future matter with respect to the applicable Mortgage Loan or any other Mortgage
Loan. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Certificateholder
(regardless of whether a Control Termination Event has occurred and is continuing), the Special Servicer shall consult with the
Operating Advisor, on a non-binding basis, in connection with the related transactions involving proposed Major Decisions and
consider alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth
in this Section 6.08 for consulting with the Operating Advisor.

 

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

 

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

 

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

 

     -360-

     

    

 

items
are actually required to be provided to the Directing Certificateholder under this Agreement due to the occurrence of a Control
Termination Event or a Consultation Termination Event).

 

In
addition, with respect to any Mortgage Loan other than an Excluded Loan with respect to the Directing Certificateholder or the
Holder of the majority of the Controlling Class, for so long as no Control Termination Event has occurred and is continuing, the
Directing Certificateholder subject to any rights, if any, of the related Companion Holder to advise the Special Servicer with
respect to the related Serviced Whole Loan, pursuant to the terms of the related Intercreditor Agreement, may direct the Special
Servicer to take, or to refrain from taking, such other actions with respect to a Mortgage Loan, as the Directing Certificateholder
may deem advisable or as to which provision is otherwise made herein; provided that notwithstanding anything herein to
the contrary, no such direction or objection contemplated by the preceding paragraphs of this section or this paragraph, may require
or cause the Master Servicer or Special Servicer to violate any provision of any Mortgage Loan or related Intercreditor Agreement
or mezzanine intercreditor agreement, applicable law, this Agreement, or the REMIC Provisions (and, with respect to a Serviced
Whole Loan, subject to the rights of the holders of the related Companion Loan), including without limitation the obligation of
the Master Servicer and the Special Servicer to act in accordance with the Servicing Standard, or expose the Master Servicer,
the Special Servicer, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer, the Trust or the
Trustee to liability, or materially expand the scope of the responsibilities of the Master Servicer or the Special Servicer, as
applicable, hereunder or cause the Master Servicer or the Special Servicer, as applicable, to act, or fail to act, in a manner
which in the reasonable judgment of the Master Servicer or the Special Servicer, as the case may be, is not in the best interests
of the Certificateholders.

 

In
the event the Special Servicer or the Master Servicer, as applicable, determines that a refusal to consent by the Directing Certificateholder
or any advice from the Directing Certificateholder or the Risk Retention Consultation Party, would cause the Special Servicer
or the Master Servicer, as applicable, to violate the terms of any Mortgage Loan, applicable law or this Agreement, including
without limitation, the Servicing Standard, the Special Servicer or the Master Servicer, as applicable, shall disregard such refusal
to consent or advise and notify the Directing Certificateholder or the Risk Retention Consultation Party, respectively, and the
Trustee and the Rating Agencies of its determination, including a reasonably detailed explanation of the basis therefor. The taking
of, or refraining from taking, any action by the Master Servicer or the Special Servicer in accordance with the direction of or
approval of the Directing Certificateholder or the approval of the Risk Retention Consultation Party that does not violate the
terms of any Mortgage Loan, applicable law or the Servicing Standard or any other provisions of this Agreement, will not result
in any liability on the part of the Master Servicer or the Special Servicer.

 

With
respect to any matter for which the consent of the Directing Certificateholder is required, to the extent no specific time period
for deemed consent is expressly stated, in the event no response from the Directing Certificateholder is received within ten (10)
Business Days following written request for consent and its receipt of all reasonably requested information on any required consent,
the Directing Certificateholder shall be deemed to have consented to or approved the specific matter; provided that the failure
of the Directing

 

     -361-

     

    

 

Certificateholder
to respond will not affect any future matters with respect to the applicable Mortgage Loan or Serviced Whole Loan.

 

The
Directing Certificateholder shall have no liability to the Trust or the Certificateholders for any action taken, or for refraining
from the taking of any action, or for errors in judgment; provided, however, that the Directing Certificateholder
shall not be protected against any liability to a Controlling Class Certificateholder that would otherwise be imposed by reason
of willful misconduct, bad faith or negligence in the performance of duties owed to the Controlling Class Certificateholders or
by reason of reckless disregard of obligations or duties owed to the Controlling Class Certificateholders. By its acceptance of
a Certificate, each Certificateholder acknowledges and agrees that the Directing Certificateholder may take actions that favor
the interests of one or more Classes of the Certificates including the Holders of the Controlling Class over other Classes of
the Certificates, and that the Directing Certificateholder may have special relationships and interests that conflict with those
of Holders of some Classes of the Certificates, that the Directing Certificateholder may act solely in the interests of the Holders
of the Controlling Class, including the Holders of the Controlling Class, that the Directing Certificateholder does not have any
duties or liability to the Holders of any Class of Certificates other than the Controlling Class, that the Directing Certificateholder
shall not be liable to any Certificateholder, by reason of its having acted solely in the interests of the Holders of the Controlling
Class, and that the Directing Certificateholder shall have no liability whatsoever for having so acted, and no Certificateholder
may take any action whatsoever against the Directing Certificateholder or any director, officer, employee, agent or principal
thereof for having so acted.

 

The
Risk Retention Consultation Party shall have no liability to the Trust or the Certificateholders for any action taken, or for
refraining from the taking of any action, or for errors in judgment; provided, however, that the Risk Retention
Consultation Party shall not be protected against any liability to a Holder of an RR Interest that would otherwise be imposed
by reason of willful misconduct, bad faith or gross negligence in the performance of duties owed to the Holders of the RR Interest
or by reason of reckless disregard of obligations or duties owed to the Holders of the RR Interest. By its acceptance of a Certificate,
each Certificateholder acknowledges and agrees that the Risk Retention Consultation Party may take actions that favor the interests
of one or more Classes of the Certificates including the Holders of an RR Interest over other Classes of the Certificates, and
that the Risk Retention Consultation Party may have special relationships and interests that conflict with those of Holders of
some Classes of the Certificates, that the Risk Retention Consultation Party may act solely in the interests of the Holders of
an RR Interest, that the Risk Retention Consultation Party does not have any duties or liability to the Holders of any Class of
Certificates other than the RR Interest, that the Risk Retention Consultation Party shall not be liable to any Certificateholder,
by reason of its having acted solely in the interests of the Holder of the RR Interest, and that the Risk Retention Consultation
Party shall have no liability whatsoever for having so acted, and no Certificateholder may take any action whatsoever against
the Risk Retention Consultation Party or any director, officer, employee, agent or principal thereof for having so acted.

 

Any
Non-Serviced Whole Loan Controlling Holder, with respect to a Non-Serviced Whole Loan, shall have no liability to the Trust or
the Certificateholders for any action taken, or for refraining from the taking of any action, or for errors in judgment. By its

 

     -362-

     

    

 

acceptance
of a Certificate, each Certificateholder acknowledges and agrees that any such Non-Serviced Whole Loan Controlling Holder, with
respect to the related Non-Serviced Whole Loan, may take actions that favor the interests of one or more classes of the certificates
issued under the related Non-Serviced PSA including the holders of the controlling class under such Non-Serviced PSA over other
classes of the certificates issued under the Non-Serviced PSA and/or any Class of Certificates, and that such Non-Serviced Whole
Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, may have special relationships and interests that conflict
with those of Holders of some Classes of the Certificates, that such Non-Serviced Whole Loan Controlling Holder, with respect
to such Non-Serviced Whole Loan, may act solely in the interests of the Holders of the controlling class under the related Non-Serviced
PSA, that such Non-Serviced Whole Loan Controlling Holder, shall not be liable to any Certificateholder, by reason of its having
acted solely in the interests of the Holders of the controlling class under the related Non-Serviced PSA, and that the Non-Serviced
Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, shall have no liability whatsoever for having so
acted, and no Certificateholder may take any action whatsoever against such Non-Serviced Whole Loan Controlling Holder, with respect
to such Non-Serviced Whole Loan, or any director, officer, employee, agent or principal thereof for having so acted.

 

(b)          Notwithstanding
anything to the contrary contained herein (i) after the occurrence and during the continuance of a Control Termination Event (and
at any time with respect to any Excluded Loan with respect to a Directing Certificateholder), the Directing Certificateholder
shall have no right to consent to or direct any action taken or not taken by any party to this Agreement; (ii) after the occurrence
and during the continuance of a Control Termination Event but prior to the occurrence and continuance of a Consultation Termination
Event, the Directing Certificateholder 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 Certificateholder 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 to the extent set forth herein; and (iii) after the occurrence and during
the continuance of a Consultation Termination Event (and at any time with respect to any Excluded Loan as to the Directing Certificateholder),
the Directing Certificateholder shall have no direction, consultation or consent rights hereunder and no right to receive any
notices, reports or information (other than notices, reports or information required to be delivered to all Certificateholders)
or any other rights as Directing Certificateholder and, other than with respect to any Excluded Loan as to the Risk Retention
Consultation Party, the Risk Retention Consultation Party shall remain entitled to receive any notices, reports or information

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

 

     -366-

     

    

 

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 shall have a forty-five (45) day period after such notice
in which to find a successor master servicer qualified to act as Master Servicer hereunder in accordance with Section 6.03
and Section 7.02 and to which the Master Servicer can sell its rights to service the Mortgage Loans under this Agreement.
During such forty-five (45) day period the Master Servicer may continue to serve as the Master Servicer hereunder. In the event
that the Master Servicer is unable, within such forty-five (45) day period, to cause a qualified successor master servicer to
assume the duties of the Master Servicer hereunder, then and in such event, the Trustee shall assume the obligations of the Master
Servicer hereunder.

 

Notwithstanding
Section 7.01(b), if any Servicer Termination Event on the part of the Special Servicer shall occur and be continuing that
affects the Holder of a Serviced Pari Passu Companion Loan, then, so long as the Special Servicer is not otherwise terminated,
the Holder of such Serviced Pari Passu Companion Loan or the Other Trustee appointed under the related Other Pooling and Servicing
Agreement, as applicable, shall be entitled to direct the Trustee to terminate the Special Servicer with respect to the related
Serviced Pari Passu Whole Loan. Any Special Servicer appointed to replace the Special Servicer with respect to a Serviced Pari
Passu Mortgage Loan cannot at any time be (without the prior written consent of the holder of such Serviced Pari Passu Companion
Loan) the person (or Affiliate thereof) that was terminated at the direction of the holder of the related Serviced Pari Passu
Companion Loan. Any Special Servicer under this paragraph shall meet the eligibility requirements of Section 7.02 and the
eligibility requirements of the related Other Pooling and Servicing Agreement, and the appointment thereof shall comply with the
provisions of Section 7.02. Any appointment of a replacement Special Servicer in accordance with this paragraph shall be
subject to the receipt of Rating Agency Confirmation and confirmation from the applicable rating agencies that such appointment
or replacement will not result in the downgrade, withdrawal or qualification of the then-current ratings of any class of any related
Serviced Companion Loan Securities (provided that such rating agency confirmation may be considered satisfied in the same
manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25).

 

(d)           Subject
to the rights of the holder of a related AB Subordinate Companion Loan pursuant to the related Intercreditor Agreement, at any
time prior to the occurrence and continuance of a Control Termination Event and other than with respect to any Excluded Loan with
respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder
shall be entitled to terminate the rights (subject to Section 3.11 and Section 6.04) and obligations of the Special
Servicer under this Agreement,

 

     -367-

     

    

 

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). Upon a termination of the Special Servicer, the Directing Certificateholder (other
than with respect to any Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority of the Controlling
Class) shall appoint a successor special servicer; provided, however, that (i) such successor will meet the requirements
set forth in Section 7.02, (ii) each Rating Agency delivers Rating Agency Confirmation and, in the case of any class of
any Serviced Companion Loan Securities, the applicable rating agencies deliver a confirmation that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25) and (iii) no replacement of the Special Servicer shall be effective until the Certificate
Administrator shall have filed any required Form 8-K pursuant to Section 11.07 and any other Form 8-K filings have been
completed with respect to any related Companion Loan.

 

After
the occurrence and during the continuance of a Control Termination Event and upon (a) the written direction of Holders of Principal
Balance Certificates evidencing not less than 25% of the Voting Rights (taking into account the application of any Appraisal Reduction
Amounts to notionally reduce the Certificate Balances pursuant to Section 4.05) of the Principal Balance Certificates (other
than the RR Interest) requesting a vote to replace the Special Servicer with a new special servicer designated in such written
direction to assume the duties of the Special Servicer hereunder, (b) payment by such Holders to the Certificate Administrator
of the reasonable fees and expenses (including any legal fees and any Rating Agency fees and expenses) to be incurred by the Certificate
Administrator in connection with administering such vote and which will not be additional expenses of the Trust and (c) delivery
by such Holders to the Certificate Administrator and Trustee of Rating Agency Confirmation from each Rating Agency (which Rating
Agency Confirmation shall be obtained at the expense of such Holders) and confirmation from the applicable rating agencies that
such appointment (or replacement) will not result in the downgrade, withdrawal or qualification of the then-current ratings of
any class of any related Serviced Pari Passu Companion Loan Securities, the Certificate Administrator shall promptly post notice
to all Certificateholders of such request on the Certificate Administrator’s Website in accordance with Section 3.13(b)
and concurrently by mail, and conduct the solicitation of votes of all Certificates (other than the RR Interest) in such regard,
which requisite affirmative votes shall be received within one hundred-eighty (180) days of the posting of such notice, and if
not so received, such votes shall be null and void ab initio. Upon the written direction of Holders of Certificates evidencing
at least 66-2/3% of a Certificateholder Quorum of Certificates, the Trustee shall terminate all of the rights and obligations
of the Special Servicer under this Agreement and appoint the successor special servicer to assume the duties of the Special Servicer
(which must be a Qualified Replacement Special Servicer) designated by such Certificateholders. The Certificate Administrator
shall include on each Distribution Date Statement a statement that each Certificateholder may (i) access such notices via the
Certificate Administrator’s Website and (ii) register to receive electronic mail notifications when such notices are posted
thereon. Notwithstanding the foregoing, the Certificateholder’s direction to remove such Special Servicer shall not apply
to

 

     -368-

     

    

 

any
Serviced AB Whole Loan for which the holder of the related AB Subordinate Companion Loan is not subject to an AB Control Appraisal
Period.

 

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

 

The
parties hereto acknowledge that, notwithstanding anything to the contrary contained in this section, in accordance with the related
Intercreditor Agreement, if a servicer termination event on the part of a Non-Serviced Special Servicer under a Non-Serviced PSA
remains unremedied and affects the holder of the related Non-Serviced Mortgage Loan, and the related Non-Serviced Special Servicer
has not otherwise been terminated, the holder of the related Non-Serviced Mortgage Loan (or the Trustee, acting at the direction
of the Directing Certificateholder) will be entitled to direct the related Non-Serviced Trustee to terminate the related Non-Serviced
Special Servicer solely with respect to the related Non-Serviced Whole Loan. The appointment (or replacement) of the applicable
Non-Serviced Special Servicer with respect to a Non-Serviced Whole Loan will in any event be subject to Rating Agency Confirmation
from each Rating Agency. A replacement special servicer will be selected by the related Non-Serviced Trustee or, prior to a consultation
termination event under the related Non-Serviced PSA, by the related Non-Serviced Whole Loan Controlling Holder; provided,
however, that any successor special servicer appointed to replace the Special Servicer with respect to such Non-Serviced
Whole Loan cannot at any time be the Person (or an Affiliate thereof) that was terminated at the direction of the holder of such
Non-Serviced Mortgage Loan, without the prior written consent of the Directing Certificateholder.

 

Following
the occurrence and continuance of a Consultation Termination Event, subject to the immediately succeeding paragraph, if the Operating
Advisor determines in its sole discretion exercised in good faith that the Special Servicer is not performing its duties as required
hereunder or is otherwise not acting in accordance with the Servicing Standard, the Operating Advisor shall deliver to the Trustee
and the Certificate Administrator, with a copy to the Special Servicer, a written report in the form of Exhibit W attached
hereto, setting forth the reasons supporting its recommendation (along with any information the Operating Advisor considered relevant
to its recommendation) and recommending a replacement Special Servicer (which form may be modified or supplemented from time to
time to cure any ambiguity or error or to incorporate any additional information, subject to compliance of such form with the
terms and provisions of this Agreement; provided, further, that in no event shall the information or any

 

     -369-

     

    

 

other
content included in such written recommendation contravene any provision of this Agreement) detailing the reasons supporting its
recommendation (along with relevant information justifying its recommendation) and recommending a suggested replacement special
servicer to assume the duties of the Special Servicer, which shall be a Qualified Replacement Special Servicer. In such event,
the Certificate Administrator shall promptly post notice to all Certificateholders of such recommendation and the related report
on the Certificate Administrator’s Website in accordance with Section 3.13(b), and by mail conduct the solicitation
of votes of all Certificates in such regard. Upon (i) the affirmative vote of Holders of Principal Balance Certificates evidencing
at least a majority of the aggregate Voting Rights (taking into account the application of any Appraisal Reduction Amounts to
notionally reduce the respective Certificate Balances of such Certificates) of all Principal Balance Certificates on an aggregate
basis within 180 days of posting of the Operating Advisor’s recommendation to the Certificate Administrator’s Website,
and if not so received, such votes shall be null and void ab initio, and (ii) receipt by the Certificate Administrator
following satisfaction of the foregoing clause (i) of Rating Agency Confirmation from each Rating Agency and confirmation
from the applicable rating agencies that such appointment (or replacement) will not result in the downgrade, withdrawal or qualification
of the then-current ratings of any class of any related Serviced Pari Passu Companion Loan Securities, the Trustee shall (i) terminate
all of the rights and obligations of the Special Servicer under this Agreement and appoint a successor special servicer approved
by the Certificateholders and (ii) promptly notify such outgoing Special Servicer of the effective date of such termination. The
reasonable out-of-pocket costs and expenses (including reasonable legal fees and expenses of outside counsel) associated with
obtaining such Rating Agency Confirmations and administering such vote and the Operating Advisor’s identification of a Qualified
Replacement Special Servicer shall be an additional expense of the Trust. In the event that the Trustee does not receive at least
a majority of the requested votes, then the Trustee shall have no obligation to remove the Special Servicer. Prior to the appointment
of any replacement special servicer, such replacement special servicer shall have agreed to succeed to the obligations of the
Special Servicer under this Agreement and to act as the Special Servicer’s successor hereunder. Notwithstanding the foregoing,
the Operating Advisor shall not be permitted to recommend the replacement of a Special Servicer with respect to an AB Whole Loan
so long as the related Serviced Companion Noteholder is not subject to an AB Control Appraisal Period under the related Intercreditor
Agreement.

 

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”

 

     -370-

     

    

 

status
or downgraded due to servicing or special servicing, as applicable, concerns by any Rating Agency with respect to the Master Servicer
or Special Servicer, as applicable. In no event shall the remedy for a breach of the foregoing covenant extend beyond termination
pursuant to Section 7.01(a)(viii) 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).

 

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

 

(g)           Notwithstanding
anything to the contrary contained in this Section 7.01, with respect to any Excluded Special Servicer Loan, if any, the
related Special Servicer shall resign as Special Servicer of that Excluded Special Servicer Loan. Prior to the occurrence and
continuance of a Control Termination Event, if the applicable Excluded Special Servicer Loan is not also an Excluded Loan with
respect to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder
shall select an Excluded Special Servicer, as successor to the resigning Special Servicer, for the related Excluded Special Servicer
Loan in accordance with this Agreement. After the occurrence and during the continuance of a Control Termination Event or if at
any time the applicable Excluded Special Servicer Loan is also an Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class, the resigning Special Servicer shall select the related Excluded Special
Servicer. The resigning Special Servicer shall not have any liability with respect to the actions or inactions of the applicable
Excluded Special Servicer or with respect to the identity of the applicable Excluded Special Servicer. It shall be a condition
to any such appointment that (i) the Rating Agencies confirm that the appointment would not result in a qualification, downgrade
or withdrawal of any of their then-current ratings of the Certificates and each NRSRO hired to provide ratings with respect to
any Serviced Companion Loan Securities makes the equivalent confirmation, (ii) the related Excluded Special Servicer is a Qualified
Replacement Special Servicer and (iii) the related Excluded Special Servicer delivers to the Depositor and the Certificate Administrator
and any applicable Other Depositor and Other Certificate Administrator, the information, if any, required under Item 6.02 of Form
8-K pursuant to the Exchange Act regarding itself in its role as Excluded Special Servicer.

 

If
at any time the Special Servicer that had previously acted as the Special Servicer is no longer a Borrower Party with respect
to an Excluded Special Servicer Loan (including, without limitation, as a result of the related Mortgaged Property becoming REO
Property), (1) the related Excluded Special Servicer shall resign, (2) the related Mortgage Loan or Serviced Whole Loan shall
no longer be an Excluded Special Servicer Loan, (3) such original Special Servicer shall become the Special Servicer again for
such related Mortgage Loan or

 

     -371-

     

    

 

Serviced
Whole Loan and (4) such original Special Servicer shall be entitled to all special servicing compensation with respect to such
Mortgage Loan or Serviced Whole Loan earned during such time on and after such Mortgage Loan or Serviced Whole Loan is no longer
an Excluded Special Servicer Loan.

 

The
applicable Excluded Special Servicer shall perform all of the obligations of the Special Servicer for the related Excluded Special
Servicer Loan and shall be entitled to all special servicing compensation with respect to such Excluded Special Servicer Loan
earned during such time as the related Mortgage Loan or Serviced Whole Loan is an Excluded Special Servicer Loan.

 

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

 

Section
7.02     Trustee to Act; Appointment of Successor. On and after the time the Master Servicer or
the Special Servicer, as the case may be, either resigns pursuant to clause (a) of Section 6.05 or receives a
notice of termination for cause pursuant to Section 7.01(b), and provided that no acceptable successor has been
appointed within the time period specified in Section 7.01(c), the Trustee shall be the successor to such party, until
such successor to that Master Servicer or that Special Servicer, as applicable, is appointed as provided in this Section
7.02 or by the Directing Certificateholder as provided in Section 7.01(d), as applicable, in all respects in its
capacity as the Master Servicer or the Special Servicer, as applicable, under this Agreement and the transactions set forth
or provided for herein and shall be subject to, and have the benefit of, all of the rights, (subject to Section 3.11 and Section
6.04) benefits, responsibilities, duties, liabilities and limitations on liability relating thereto and that arise
thereafter placed on or for the benefit of the Master Servicer or Special Servicer, as applicable, by the terms and
provisions hereof; provided, however, that any failure to perform such duties or responsibilities caused by the
terminated party’s failure under Section 7.01 to provide information or moneys required hereunder shall not be
considered a default by such successor hereunder. The appointment of a successor master servicer shall not affect any
liability of the predecessor Master Servicer which may have arisen prior to its termination as Master Servicer, and the
appointment of a successor special servicer shall not affect any liability of the predecessor Special Servicer which may have
arisen prior to its termination as Special Servicer. The Trustee in its capacity as successor to the Master Servicer or the
Special Servicer, as the case may be, shall not be liable for any of the representations and warranties of the Master
Servicer or the Special Servicer, respectively, herein or in any related document or agreement, for any acts or omissions of
the predecessor master servicer or special servicer or for any losses incurred by the predecessor Master Servicer pursuant to Section
3.06 hereunder, nor shall the Trustee be required to purchase any Mortgage Loan hereunder solely as a result of its
obligations as successor master servicer or special servicer, as the case may be. Subject to Section 3.11, as
compensation therefor, the Trustee as successor master servicer shall be entitled to the Servicing Fees and all fees relating
to the Mortgage Loans or the Companion Loans which that Master Servicer would have been entitled to if the Master
Servicer had continued to act hereunder,

 

     -372-

     

    

 

including
but not limited to any income or other benefit from any Permitted Investment pursuant to Section 3.06, and subject to Section
3.11, and the Trustee as successor to the Special Servicer shall be entitled to the Special Servicing Fees to which the Special
Servicer would have been entitled if the Special Servicer had continued to act hereunder. Should the Trustee succeed to the capacity
of the Master Servicer or the Special Servicer, as the case may be, the Trustee shall be afforded the same standard of care and
liability as the Master Servicer or the Special Servicer, as applicable, hereunder notwithstanding anything in Section 8.01
to the contrary, but only with respect to actions taken by it in its role as successor master servicer or successor special
servicer, as the case may be, and not with respect to its role as Trustee hereunder. Notwithstanding the above, the Trustee may,
if it shall be unwilling to act as successor to that Master Servicer or that Special Servicer, as applicable, or shall, if it
is unable to so act, or if the Trustee is not approved as a servicer by each Rating Agency, or if the Directing Certificateholder
(solely with respect to the Special Servicer) ((i) prior to the occurrence and continuance of a Control Termination Event and
(ii) other than with respect to any Excluded Loan with respect to the Directing Certificateholder or the Holder of the majority
of the Controlling Class) or the Holders of Certificates entitled to more than 50% of the Voting Rights so request in writing
to the Trustee, promptly appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing
institution which meets the criteria set forth in Section 6.05 and otherwise herein, as the successor to that Master Servicer
or that Special Servicer, as applicable, hereunder in the assumption of all or any part of the responsibilities, duties or liabilities
of the Master Servicer or the Special Servicer hereunder. No appointment of a successor to the Master Servicer or the Special
Servicer hereunder shall be effective until (i) the assumption in writing by the successor to the Master Servicer or the Special
Servicer of all its responsibilities, duties and liabilities hereunder that arise thereafter, (ii) receipt of Rating Agency Confirmation
from each Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade,
withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25), (iii) such appointment (solely with respect to the
Special Servicer) has been approved (prior to the occurrence and continuance of a Control Termination Event) by the Directing
Certificateholder, such approval not to be unreasonably withheld and (iv) the Certificate Administrator shall have filed any required
Form 8-K pursuant to Section 11.07 and any other Form 8-K filings have been completed with respect to any related Companion
Loan. Pending appointment of a successor to the Master Servicer or the Special Servicer hereunder, unless the Trustee shall be
prohibited by law from so acting, the Trustee shall act in such capacity as herein above provided. In connection with such appointment
and assumption of a successor to the Master Servicer or the Special Servicer as described herein, the Trustee may make such arrangements
for the compensation of such successor out of payments on the Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation with respect to a successor master servicer or successor special servicer, as the case
may be, shall be in excess of that permitted the terminated Master Servicer or Special Servicer, as the case may be, hereunder.
The Trustee, the non-terminated Master Servicer or the non-terminated Special Servicer and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such succession. Any reasonable out-of-pocket costs and
expenses associated with the transfer of the servicing function (other than with respect to a termination without cause) under
this Agreement shall be borne by

 

     -373-

     

    

 

the predecessor Master Servicer or Special Servicer, as applicable. If such predecessor Master
Servicer or Special Servicer (as the case may be) has not reimbursed the party requesting such termination or the successor master
servicer or special servicer for such expenses within 90 days after the presentation of reasonable documentation, such expense
shall be reimbursed by the Trust; provided that the terminated Master Servicer or Special Servicer shall not thereby be
relieved of its liability for such expenses. If and to the extent that the terminated Master Servicer or Special Servicer has
not reimbursed such costs and expenses, the party requesting such termination shall have an affirmative obligation to take all
reasonable actions to collect such expenses on behalf of the Trust. In the event of a termination without cause, such costs and
expenses shall be borne by the party requesting such termination, or as otherwise set forth herein; provided that the Certificate
Administrator and the Trustee shall not bear any such costs and expenses. For the avoidance of doubt, if the Trustee is terminating
the Master Servicer or the Special Servicer in accordance with this Agreement at the direction of any party or parties permitted
to direct the Trustee to so terminate the Master Servicer or the Special Servicer pursuant to this Agreement, the Trustee shall
not have any liability for such expenses pursuant to this paragraph.

 

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

 

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

 

Section
7.04     Waiver of Servicer Termination Events. The Holders of Certificates representing at least
66-2/3% of the Voting Rights allocated to each Class of Certificates affected by any Servicer Termination Event hereunder may
waive such Servicer Termination Event; provided, however, that a Servicer Termination Event under clause (i),
(ii) or (viii) of Section 7.01(a) may be waived only with the consent of all of the Certificateholders of
the affected Classes, and a Servicer Termination Event under clause (iii) of Section 7.01(a) (with respect to obligations
under Article XI) may be waived only with the consent of the Depositor. Upon any such waiver of a Servicer Termination
Event, subject to the rights of any affected holder of a Serviced Companion Loan under Section 7.01(c) or Section 7.01(f),
such Servicer Termination Event shall cease to exist and shall be deemed to have been remedied for every purpose hereunder. Upon
any such waiver of a Servicer Termination Event by Certificateholders, the Trustee and the Certificate Administrator shall be
entitled to recover all costs and expenses incurred by it in connection with enforcement action taken with respect to such Servicer
Termination Event prior to such waiver from the Trust. No such waiver shall extend to any subsequent or other Servicer Termination
Event or impair any right consequent

 

     -374-

     

    

 

thereon
except to the extent expressly so waived. Notwithstanding any other provisions of this Agreement, for purposes of waiving any
Servicer Termination Event pursuant to this Section 7.04, Certificates registered in the name of the Depositor or any Affiliate
of the Depositor shall be entitled to the same Voting Rights with respect to the matters described above as they would if any
other Person held such Certificates.

 

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

the correction thereof. The Trustee or the Certificate Administrator shall not be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other instrument furnished by the Depositor, the Master
Servicer or the Special Servicer or another Person, and accepted by the Trustee or the Certificate Administrator in good faith,
pursuant to this Agreement.

 

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

 

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

of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee
or the Certificate Administrator and conforming to the requirements of this Agreement;

 

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

to be taken by it in good faith in accordance with the direction of Holders of Certificates entitled to greater than 25% (i) of
the Percentage Interest of each affected Class, or (ii) if each Class is an affected Class of the aggregate Voting Rights of the
Certificates, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee or the
Certificate Administrator, or exercising any trust or power conferred upon the Trustee or the Certificate Administrator, under
this Agreement (unless a higher percentage of Voting Rights is required for such action).

(d)           The
Certificate Administrator shall make available via its internet website initially located at www.ctslink.com to the Serviced Companion

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

 

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

 

(ii)           The
Trustee and the Certificate Administrator may consult with counsel and the advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good
faith and in accordance therewith;

 

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

 

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

 

(v)           Prior
to the occurrence of a Servicer Termination Event hereunder and after the curing of all Servicer Termination Events which may
have occurred, neither the Trustee nor the Certificate Administrator shall be bound to make any investigation into

 

     -377-

     

    

 

the facts or
matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval,
bond or other paper or document, unless requested in writing to do so by Holders of Certificates entitled to more than 50% of
the Voting Rights; provided, however, that if the payment within a reasonable time to the Trustee or the Certificate
Administrator of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the
opinion of the Trustee or the Certificate Administrator, respectively, not reasonably assured to the Trustee or the Certificate
Administrator by the security afforded to it by the terms of this Agreement, the Trustee or the Certificate Administrator, respectively,
may require indemnity reasonably satisfactory to it from such requesting Holders against such expense or liability as a condition
to taking any such action. The reasonable expense of every such reasonable examination shall be paid by the requesting Holders;

 

(vi)          The
Trustee or the Certificate Administrator may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents or attorneys; provided, however, that the appointment of such agents or attorneys
shall not relieve the Trustee or the Certificate Administrator of its duties or obligations hereunder; provided, further,
that the Trustee or the Certificate Administrator, as the case may be, may not perform any duties hereunder through any Person
that is a Prohibited Party;

 

(vii)         For
all purposes under this Agreement, none of the Trustee, the Custodian or the Certificate Administrator shall be deemed to have
actual knowledge or notice of any Servicer Termination Event or Asset Representations Reviewer Termination Event or any act, failure
or breach of any Person upon the occurrence of which the Trustee or Certificate Administrator may be required to act unless a
Responsible Officer of the Trustee or the Certificate Administrator, as applicable, has actual knowledge thereof or unless written
notice of any event, act, failure or breach, as applicable, which is in fact such a default is received by the Trustee or the
Certificate Administrator at the respective Corporate Trust Office, and such notice references the Certificates or this Agreement;

 

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

 

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

 

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

 

     -378-

     

    

 

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

 

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

 

Each
of the Trustee and the Certificate Administrator shall be entitled to all of the same rights, protections, immunities and indemnities
afforded to it as Trustee and Certificate Administrator, as the case may be, in each capacity for which it serves hereunder (including,
without limitation, as Custodian, Certificate Registrar, 17g-5 Information Provider and Authenticating Agent).

 

Section
8.03     Trustee and Certificate Administrator Not Liable for Validity or Sufficiency of
Certificates or Mortgage Loans. The recitals contained herein and in the Certificates, other than the acknowledgments of
the Trustee or the Certificate Administrator in Sections 2.01(h) and Section 2.04 and the signature, if any, of
the Certificate Registrar and Authenticating Agent set forth on any outstanding Certificate, shall not be taken as the
statements of the Trustee or the Certificate Administrator, and the Trustee or the Certificate Administrator assume no
responsibility for their correctness. Neither the Trustee nor the Certificate Administrator makes any representations as to
the validity or sufficiency of this Agreement or of any Certificate (other than as to the signature, if any, of the Trustee
or the Certificate Administrator set forth thereon) or of any Mortgage Loan or related document. Neither the Trustee nor the
Certificate Administrator shall be accountable for the use or application by the Depositor of any of the Certificates issued
to it or of the proceeds of such Certificates, or for the use or application of any funds paid to the Depositor in respect of
the assignment of the Mortgage Loans to the Trust, or any funds deposited in or withdrawn from the Collection Account or any
other account by or on behalf of the Depositor, the Master Servicer, the Special Servicer or in the case of the Trustee, the
Certificate Administrator. The Trustee and the Certificate Administrator shall not be responsible for and may rely upon the
accuracy or content of any resolution, certificate, statement, opinion, report, document, order or other instrument furnished
by the Depositor, the Master Servicer or the Special Servicer and accepted by the Trustee or the Certificate Administrator,
in good faith, pursuant to this Agreement.

 

Section
8.04   Trustee or Certificate Administrator May Own Certificates. The Trustee or the
Certificate Administrator, each in its individual capacity, not as Trustee or Certificate Administrator, may become the owner
or pledgee of Certificates, and may deal with the Depositor, the Master Servicer, the Special Servicer or the Underwriters in
banking transactions, with the same rights it would have if it were not Trustee or the Certificate Administrator.

 

Section
8.05     Fees and Expenses of Trustee and Certificate Administrator; Indemnification of Trustee and
Certificate Administrator. (a)As compensation for the performance of their respective duties hereunder, the Trustee will be
paid the Trustee Fee, which shall cover recurring and otherwise reasonably anticipated expenses of the Trustee, and the Certificate
Administrator will be paid the Certificate Administrator Fee equal to the Certificate Administrator’s portion of one (1)
month’s interest at the Certificate Administrator Fee Rate,

 

     -379-

     

    

 

which shall cover recurring and otherwise reasonably anticipated
expenses of the Certificate Administrator. The Trustee Fee and Certificate Administrator Fee shall be paid monthly on a Mortgage
Loan-by-Mortgage Loan basis. As to each Mortgage Loan and REO Loan (other than the portion of an REO Loan related to any Companion
Loan), the Certificate Administrator shall pay to the Trustee monthly the Trustee Fee from the Certificate Administrator Fee,
which Certificate Administrator Fee shall accrue from time to time at the Certificate Administrator Fee Rate and the Certificate
Administrator Fee shall be computed in the same manner as interest is calculated thereon and for the same period respecting which
any related interest payment due or deemed thereon is computed. The Trustee Fee (which shall not be limited to any provision of
law in regard to the compensation of a trustee of an express trust) shall constitute the Trustee’s sole form of compensation
for all services rendered by it in the execution of the trusts hereby created and in the exercise and performance of any of the
powers and duties of the Trustee hereunder, except for the reimbursement of expenses specifically provided for herein. The Certificate
Administrator Fee shall constitute the Certificate Administrator’s sole form of compensation for the exercise and performance
of its powers and duties hereunder, except for the reimbursement of expenses specifically provided for herein. No Trustee Fee
or Certificate Administrator Fee shall be payable with respect to any Companion Loan.

 

(b)          The
Trustee, the Certificate Administrator (in each case, including in its capacity as Custodian and in its individual capacity) and

     -380-

     

    

 

shall

Section
8.06     Eligibility Requirements for Trustee and Certificate Administrator. Each of the
Trustee and the Certificate Administrator hereunder shall at all times be, and will be required to resign if it fails to be,
(i) a corporation, national bank, national banking association or a trust company, organized and doing business under the
laws of any state or the United States of America, authorized under such laws to exercise corporate trust powers and to
accept the trust conferred under this Agreement, having a combined capital and surplus of at least $100,000,000 and subject
to supervision or examination by federal or state authority and in the case of the Trustee, shall not be an Affiliate of the
Master Servicer or the Special Servicer (except during any period when the Trustee is acting as, or has become successor to,
the Master Servicer or the Special Servicer, as the case may be, pursuant to Section 7.02), (ii) an institution
insured by the Federal Deposit Insurance Corporation, (iii) an institution whose long-term senior unsecured debt is rated at
least “A2” by Moody’s, “A-” by Fitch and, if rated by KBRA, “A” by KBRA; provided
that the Trustee will not become ineligible to serve based on a failure to satisfy such rating requirements as long as (a) it
maintains a long-term unsecured debt rating of no less than “Baa2” by Moody’s and “A-” by
Fitch, (b) its short-term debt obligations have a short-term rating of not less than “P-2” from Moody’s and
“F1” by Fitch and (c) the Master Servicer maintains a rating of at least “A2” by Moody’s and
“A+” by Fitch; provided that nothing in this clause (c) shall impose on the Master Servicer any
obligation to maintain such rating; provided, further, that if any such institution is not rated by KBRA, such
institution maintains an equivalent (or higher) rating by any two other NRSROs (which may include Moody’s and/or Fitch)
or such other rating with respect to which the Rating Agencies have provided a Rating Agency Confirmation and (iv) an entity
that is not a Prohibited Party.

 

If
such corporation, national bank or national banking association publishes reports of condition at least annually, pursuant to
law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.06
the combined capital and surplus of such corporation, national bank or national banking association shall be deemed to be
its combined capital and surplus as set forth in its most recent report of condition so published. In the event the place of business
from which the Certificate Administrator administers the Trust REMICs or in which the Trustee’s office is located is in
a state or local jurisdiction that imposes a tax on the Trust on the net income of a REMIC (other than a tax

 

     -381-

     

    

 

corresponding
to a tax imposed under the REMIC Provisions), the Certificate Administrator or the Trustee, as applicable shall elect either to
(i) resign immediately in the manner and with the effect specified in Section 8.07, (ii) pay such tax at no expense to
the Trust or (iii) administer the Trust REMICs from a state and local jurisdiction that does not impose such a tax.

 

Section
8.07     Resignation and Removal of the Trustee and Certificate Administrator. (a)The Trustee
and the Certificate Administrator may at any time resign and be discharged from the trusts hereby created by giving written
notice thereof to the Depositor, the Master Servicer, the Special Servicer and the Trustee or the Certificate Administrator,
as applicable, the Operating Advisor, the Asset Representations Reviewer, 17g-5 Information Provider and to all
Certificateholders. The Certificate Administrator shall post such notice to the Certificate Administrator’s Website in
accordance with Section 3.13(b) and provide notice of such event to the Master Servicer, the Special Servicer, the
Depositor and the 17g-5 Information Provider, which shall promptly post such notice to the 17g-5 Information Provider’s
Website in accordance with Section 3.13(c). Upon receiving such notice of resignation, the Depositor shall use its
reasonable best efforts to promptly appoint a successor trustee or successor certificate administrator acceptable to the
Master Servicer and, prior to the occurrence and continuance of a Control Termination Event, the Directing Certificateholder
by written instrument, in duplicate, which instrument shall be delivered to the resigning Trustee or Certificate
Administrator and to the successor trustee or certificate administrator. A copy of such instrument shall be delivered to the
Master Servicer, the Special Servicer, the Certificateholders and the Trustee or Certificate Administrator, as applicable, by
the Depositor. If no successor trustee or certificate administrator shall have been so appointed and have accepted
appointment within ninety (90) days after the giving of such notice of resignation, the resigning Trustee or Certificate
Administrator may petition any court of competent jurisdiction for the appointment of a successor trustee or certificate
administrator, as applicable, and such petition will be an expense of the Trust.

 

(b)          If
at any time the Trustee or Certificate Administrator shall cease to be eligible in accordance with the provisions of Section
8.06 (and in the case of the Certificate Administrator, Section 5.08) and shall fail to resign after written request
therefor by the Depositor or the Master Servicer, or if at any time the Trustee or Certificate Administrator shall become incapable
of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or the Certificate Administrator or of its
property shall be appointed, or any public officer shall take charge or control of the Trustee or Certificate Administrator or
of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or if the Trustee or Certificate Administrator
(if different than the Trustee) shall fail to timely publish any report to be delivered, published or otherwise made available
by the Certificate Administrator pursuant to Section 4.02 and such failure shall continue unremedied for a period of five
(5) days, or if the Certificate Administrator fails to make distributions required pursuant to Section 4.01 or Section
9.01, then the Depositor may remove the Trustee or Certificate Administrator, as applicable, and appoint a successor trustee
or certificate administrator acceptable to the requesting Master Servicer, by written instrument, in duplicate, which instrument
shall be delivered to the Trustee or Certificate Administrator so removed and to the successor trustee or certificate administrator
in the case of the removal of the Trustee or Certificate Administrator. A copy of such instrument shall be delivered to the Master
Servicer, the Special Servicer and the Certificateholders by the Depositor. If no successor trustee or certificate administrator
shall have

 

     -382-

     

    

 

been
so appointed and have accepted appointment within ninety (90) days after the giving of such notice of removal, the removed Trustee
or Certificate Administrator may petition any court of competent jurisdiction for the appointment of a successor trustee or certificate
administrator, as applicable, at the expense of the Trust.

 

(c)          The
Holders of Certificates entitled to at least 75% of the Voting Rights may, upon thirty (30) days’ prior written notice,
with or without cause, remove the Trustee or Certificate Administrator and appoint a successor trustee or certificate administrator
by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete
set of which instruments shall be delivered to the Master Servicer, one complete set to the Trustee or Certificate Administrator
so removed and one complete set to the successor so appointed. A copy of such instrument shall be delivered to the Depositor,
the Special Servicer and the remaining Certificateholders by the Master Servicer. In the event of any such termination without
cause pursuant to this Section 8.07(c), the successor trustee or certificate administrator, as applicable, shall be responsible
for all costs and expenses necessary to effect the transfer of responsibilities from its predecessor.

 

(d)          Any
resignation or removal of the Trustee or Certificate Administrator and appointment of a successor trustee or certificate administrator
pursuant to any of the provisions of this Section 8.07 shall not become effective until (i) acceptance of appointment by
the successor trustee or certificate administrator as provided in Section 8.08 and (ii) the Certificate Administrator shall
have filed any required Form 8-K pursuant to Section 11.07 and any other Form 8-K filings have been completed with respect
to any related Companion Loan. Further, the resigning Trustee or Certificate Administrator, as the case may be, shall pay all
costs and expenses associated with the transfer of its duties.

 

If
the same party is acting as Trustee and Certificate Administrator pursuant to this Agreement, any removal of either such party
in its capacity as Trustee or Certificate Administrator, as applicable, shall also result in such party’s removal in its
capacity as Trustee or Certificate Administrator, as applicable, and the Depositor shall appoint a successor certificate administrator
and a successor trustee, in each instance meeting the eligibility requirements set forth hereunder.

 

Upon
any succession of the Trustee or Certificate Administrator under this Agreement, the predecessor Trustee or Certificate Administrator
shall be entitled to the payment of accrued and unpaid compensation and reimbursement as provided for under this Agreement for

shall be personally liable for any action or omission of any successor trustee or certificate administrator.

the resignation, assignment, merger, consolidation, or transfer of the Trustee or its business to a successor, or upon the termination
of the Trustee, (a) the outgoing Trustee shall (i) endorse the original executed Mortgage Note for each Mortgage Loan (to the
extent that the original executed Mortgage Note for each Mortgage Loan was endorsed to the outgoing trustee), without recourse,
representation or warranty, express or implied, to the order of the successor, as trustee for the registered Holders of BANK 2017-BNK4,
Commercial Mortgage Pass-Through Certificates, Series 2017-BNK4 or in blank, and (ii) in the case of the

 

     -383-

     

    

 

other
assignable Mortgage Loan documents (to the extent such other Mortgage Loan documents were assigned to the outgoing trustee), assign
such Mortgage Loan documents to such successor, and such successor shall review the documents delivered to it or to the Custodian
with respect to each Mortgage Loan, and certify in writing that, as to each Mortgage Loan then subject to this Agreement, such
endorsement and assignment has been made; (b) if any original executed Mortgage Note for a Mortgage Loan was not endorsed to the
outgoing trustee, the Custodian shall, upon its receipt of a Request for Release, deliver such Mortgage Note to the Depositor
or the successor trustee, as requested, and the Master Servicer and the Depositor shall cooperate with any successor trustee to
ensure that such Mortgage Note is endorsed (without recourse, representation or warranty, express or implied) to the order of
the successor, as trustee for the registered Holders of BANK 2017-BNK4, Commercial Mortgage Pass-Through Certificates, Series
2017-BNK4 or in blank; provided, however, that, notwithstanding anything to the contrary herein, to the extent any
such endorsement of such Mortgage Note requires the signature of the related Mortgage Loan Seller in order to comply with the
foregoing, then the Master Servicer shall use reasonable efforts to cause the related Mortgage Loan Seller to execute such endorsement;
(c) if any other assignable Mortgage Loan document was not assigned to the outgoing trustee, the Custodian shall, upon its receipt
of a Request for Release, deliver such Mortgage Loan document to the Depositor or the successor trustee, as requested, and the

to such successor trustee; and (d) in any case, such successor trustee shall review the documents delivered to it or to the Custodian
with respect to each Mortgage Loan, and certify in writing that, as to each Mortgage Loan then subject to this Agreement, such
endorsements and assignments have been made or, in the event such endorsement or assignment cannot be made for any reason, to
note the same in such certification.

 

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

 

Section

certificate administrator appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the
Depositor, the Master Servicer, the Special Servicer and to its predecessor Trustee or Certificate Administrator an
instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee or
Certificate Administrator shall become effective and such successor trustee or certificate administrator without any further
act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with the like effect as if originally named as Trustee or Certificate Administrator herein. The predecessor
Trustee shall deliver to the successor trustee all Mortgage Files and related documents and statements held by it hereunder
(other than any Mortgage Files at the time held on its behalf by the Custodian, which Custodian, at Custodian’s option
shall become the agent of the successor trustee), and the Depositor, the Master Servicer, the Special Servicer and the
predecessor Trustee shall execute and deliver such instruments and do such other things as may reasonably be required to more
fully and certainly vest and confirm in the successor trustee all such rights, powers, duties and obligations, and to enable
the successor trustee to perform its obligations hereunder.

 

(b)          No
successor trustee or successor certificate administrator shall, as applicable, accept appointment as provided in this Section
8.08 unless at the time of such

 

     -384-

     

    

 

acceptance
such successor trustee or successor certificate administrator, as applicable, shall be eligible under the provisions of Section

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

Depositor and the Certificateholders. If the Master Servicer fails to deliver such notice within ten (10) days after acceptance
of appointment by the successor trustee or successor certificate administrator, as applicable, such successor trustee or successor
certificate administrator shall cause such notice to be delivered at the expense of the Master Servicer.

 

Section
8.09     Merger or Consolidation of Trustee or Certificate Administrator. Any Person into which
the Trustee or the Certificate Administrator may be merged or converted or with which it may be consolidated or any Person
resulting from any merger, conversion or consolidation to which the Trustee or the Certificate Administrator shall be a
party, or any Person succeeding to all or substantially all of the corporate trust business of the Trustee or the Certificate
Administrator shall be the successor of the Trustee or the Certificate Administrator, as applicable, hereunder; provided
that, in the case of the Trustee, such successor person shall be eligible under the provisions of Section 8.06,
without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to
the contrary notwithstanding. The Certificate Administrator shall post such notice to the Certificate Administrator’s
Website in accordance with Section 3.13(b) and shall provide notice of such event to the Master Servicer, the Special
Servicer, the Depositor and the 17g-5 Information Provider, which shall post such notice to the 17g-5 Information
Provider’s Website in accordance with Section 3.13(c).

 

Section
8.10     Appointment of Co-Trustee or Separate Trustee. (a) Notwithstanding any other
provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of
the Trust Fund or property securing the same may at the time be located, the Master Servicer and the Trustee acting jointly
shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to
act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of
the Trust Fund, and to vest in such Person or Persons, in such capacity, such title to the Trust, or any part thereof, and,
subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the
Master Servicer and the Trustee may consider necessary or desirable. If the Master Servicer shall not have joined in such
appointment within fifteen (15) days after the receipt by it of a request to do so, or in case a Servicer Termination Event
shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or
separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section
8.06 hereunder and no notice to Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall
be required under Section 8.08. All co-trustee fees shall be payable out of the Trust Fund.

 

(b)          In
the case of any appointment of a co-trustee or separate trustee pursuant to this Section 8.10, all rights, powers, duties
and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee
and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in

 

     -385-

     

    

 

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.

 

Section
8.11     Appointment of Custodians. The Certificate Administrator is hereby appointed as the
Custodian to hold all or a portion of the Mortgage Files. The Custodian shall be a depository institution subject to
supervision by federal or state authority, shall have combined capital and surplus of at least $15,000,000 and shall be
qualified to do business in the jurisdiction in which it holds any Mortgage File. The Custodian shall be subject to the same
obligations and standard of care as would be imposed on the Certificate Administrator hereunder in connection with the
retention of Mortgage Files directly by the Certificate Administrator. Upon termination or resignation of the Custodian, the
Certificate Administrator may appoint another Custodian meeting the foregoing requirements. The appointment of one or more
Custodians by the Certificate Administrator shall not relieve the Certificate Administrator from any of its obligations
hereunder, and the Certificate Administrator shall remain responsible for all acts and omissions of any Custodian other than
the initial Custodian. Any Custodian appointed hereunder must maintain a fidelity bond and errors and omissions policy in an
amount customary for Custodians which serve in such capacity in commercial mortgage loan securitization transactions, or may
self-insure.

 

Section
8.12     Representations and Warranties of the Trustee. The Trustee hereby represents and

whether such enforcement is considered in a proceeding in equity or at law;

 

(v)          The
Trustee is not in violation of, and its execution and delivery of this Agreement and its performance and compliance with the terms

or demand of any federal, state or local governmental or regulatory authority, which violation, in the Trustee’s good faith
and reasonable judgment, is likely to affect materially and adversely the ability of the Trustee to perform its obligations under
this Agreement;

 

(vi)          No
litigation is pending or, to the best of the Trustee’s knowledge, threatened against the Trustee which would prohibit the

(vii)         No
consent, approval, authorization or order of any court or governmental agency or body is required for the execution, delivery
and performance by the Trustee, or compliance by the Trustee with, this Agreement or the consummation of the transactions contemplated
by this Agreement, except for any consent, approval, authorization or order which has not been obtained or cannot be obtained

continue beyond the expiration of twenty-one (21) years from the death of the last survivor of the descendants of Joseph P. Kennedy,
the late ambassador of the United States to the Court of St. James’s, living on the date hereof.

 

Following
the date on which the Class A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B, Class C and Class D Certificates
are no longer outstanding (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the

     -390-

     

    

 

Interest)),
the Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates
(other than the Class V Certificates, Class R Certificates and the RR Interest) together with the payment or deemed payment of
the Termination Purchase Amount for all of the Mortgage Loans and each REO Property remaining in the Trust Fund as contemplated

(ii) be deemed to pay to the Trust (which amount shall be further deemed distributed to the Holders of all outstanding Certificates
(other than the RR Interest)) an amount equal to the product of the Non-Retained Percentage and the Termination Purchase Amount.

however, that if a Serviced Whole Loan is secured by REO Property, the portion of the above-described purchase price allocable

as shall be necessary to effectuate transfer of the Mortgage Loans and REO Properties remaining in the Trust Fund, and the Trust
shall be liquidated in accordance with Section 9.02. Solely for federal income tax purposes, the Sole Certificateholder
shall be deemed to have purchased the assets of the Lower-Tier REMIC for an amount equal to the remaining Certificate Balance
of the Principal Balance Certificates, plus accrued, unpaid interest with respect thereto, and the Certificate Administrator shall
credit such amounts against amounts distributable in respect of such Certificates and Related Lower-Tier Regular Interests.

 

The
obligations and responsibilities under this Agreement of the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Certificate Administrator and the

 

     -391-

     

    

 

Companion
Paying Agent shall terminate with respect to any Companion Loan to the extent (i) its related Serviced Mortgage Loan has been
paid in full or is no longer part of the Trust Fund and (ii) no amounts payable by the related Companion Holder to or for the
benefit of the Trust or any party hereto in accordance with the related Intercreditor Agreement remain due and owing.

 

The
Holder of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates,
in that order of priority, may, at their option, elect to purchase all of the Mortgage Loans (and all property acquired through
exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion of each REO Property remaining in
the Trust Fund as contemplated by clause (ii) of the first paragraph of this Section 9.01 by giving written notice
to the Trustee, the Certificate Administrator, and the other parties hereto no later than sixty (60) days prior to the anticipated
date of purchase; provided, however, that the Holders of the Controlling Class, the Special Servicer, the Master
Servicer, or the Holders of the Class R Certificates may so elect to purchase all of the Mortgage Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund only on or after the first Distribution Date on which the aggregate Stated
Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate
Cut-off Date Balance of the Mortgage Loans as set forth in the Preliminary Statement. This purchase shall terminate the Trust
and retire the then-outstanding Certificates. In the event that the Master Servicer or the Special Servicer purchases, or the
Holder of the majority of the Controlling Class or the Holders of the Class R Certificates purchase, all of the Mortgage Loans
and the Trust’s portion of each REO Property remaining in the Trust Fund in accordance with the preceding sentence, the
Master Servicer, the Special Servicer, the Holder of the majority of the Controlling Class or the Holders of the Class R Certificates,
as the case may be, shall deposit in the Lower-Tier REMIC Distribution Account not later than the P&I Advance Date relating
to the Distribution Date on which the final distribution on the Certificates is to occur, an amount in immediately available funds
equal to the above-described purchase price (exclusive of any portion thereof payable to any Person other than the Certificateholders
pursuant to Section 3.05(a), which portion shall be deposited in the Collection Account). In addition, the Master Servicer
shall transfer to the Lower-Tier REMIC Distribution Account all amounts required to be transferred thereto on such P&I Advance
Date from the Collection Account pursuant to the first paragraph of Section 3.04(b), together with any other amounts on
deposit in the Collection Account that would otherwise be held for future distribution. Upon confirmation that such final deposits
and payments have been made, the Custodian shall release or cause to be released to the Master Servicer, the Special Servicer,
the Holder of the majority of the Controlling Class or the Holders of the Class R Certificates, as applicable, the Mortgage Files
for the remaining Mortgage Loans and shall execute all assignments, endorsements and other instruments furnished to it by the
Master Servicer, the Special Servicer, the Holder of the majority of the Controlling Class or the Holders of the Class R Certificates,
as the case may be, as shall be necessary to effectuate transfer of the Mortgage Loans as assets of the Trust and REO Properties
remaining in the Trust Fund.

 

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

 

     -392-

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

ADDITIONAL REMIC PROVISIONS

 

Section
10.01   REMIC Administration. (a) The Certificate Administrator shall make elections or cause elections
to be made to treat each Trust REMIC as a REMIC under the Code and, if necessary, under Applicable State and Local Tax Law.
Each such election will be made on Form 1066 or other appropriate federal tax return for the taxable year ending on the last
day of the calendar year in which the Lower-Tier Regular Interests and the Certificates are issued. For the purposes of the
REMIC election in respect of the Upper-Tier REMIC, each Class of the Regular Certificates shall be designated the
“regular interests,” and the Class UR Interest shall be designated the sole class of “residual
interests” in the Upper-Tier REMIC. For purposes of the REMIC election in respect of the Lower-Tier REMIC, each Class
of Lower-Tier Regular Interests shall be designated as a class of “regular interests” and the Class LR Interest
shall be designated as the sole class of “residual interests” in the Lower-Tier REMIC. None of the Special
Servicer, the Master Servicer or the Trustee shall permit the creation of any “interests” (within the meaning of
Section 860G of the Code) in any Trust REMIC other than the foregoing interests.

 

(b)          The
Closing Date is hereby designated as the “startup day” (“Startup Day”) of each Trust REMIC within
the meaning of Section 860G(a)(9) of the Code.

 

(c)          The
Certificate Administrator shall act on behalf of each Trust REMIC in relation to any tax matter or controversy involving either
such REMIC and shall represent each such REMIC in any administrative or judicial proceeding relating to an examination or audit
by any governmental taxing authority with respect thereto. The legal expenses, including without

 

     -394-

     

    

 

limitation
attorneys’ or accountants’ fees, and costs of any such proceeding and any liability resulting therefrom shall be expenses
of the Trust and the Certificate Administrator shall be entitled to reimbursement therefor out of amounts attributable to the
Mortgage Loans and any REO Properties on deposit in the Collection Account as provided by Section 3.05(a) unless such legal
expenses and costs are incurred by reason of the Certificate Administrator’s willful misconduct, bad faith or negligence.
The Holder of the largest Percentage Interest in the Class R Certificates shall be designated as the “tax matters person”
in the manner provided under Treasury Regulations Section 1.860F-4(d) and Treasury Regulations Section 301.6231(a)(7)-1, and the
“partnership representative” within the meaning of Section 6223 of the Code (to the extent such provision is applicable
to the Trust REMICs) of each Trust REMIC. By their acceptance thereof, the Holder of the largest Percentage Interest in the Class
R Certificates hereby agrees to irrevocably appoint the Certificate Administrator as its agent to perform all of the duties of
the “tax matters person” and “partnership representative” for the Trust REMICs.

 

(d)          The
Certificate Administrator shall prepare or cause to be prepared and shall file, or cause to be filed, all of the Tax Returns that
it determines are required with respect to each Trust REMIC created hereunder, and shall cause the Trustee to sign (and the Trustee
shall timely sign) such Tax Returns in a timely manner. The ordinary expenses of preparing such returns shall be borne by the
Certificate Administrator without any right of reimbursement therefor.

 

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

 

(f)          The
Certificate Administrator shall take such actions and shall cause the Trust to take such actions as are reasonably within the
Certificate Administrator’s control and the scope of its duties more specifically set forth herein as shall be necessary
to maintain the status of each Trust REMIC as a REMIC under the REMIC Provisions and the Trustee shall assist the Certificate
Administrator to the extent reasonably requested by the Certificate Administrator to do so. Neither the Master Servicer nor the
Special Servicer shall knowingly or intentionally take any action, cause the Trust to take any action or fail to take (or fail
to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that,
under the REMIC Provisions, if taken or not taken, as the case may be, could (i) cause any Trust REMIC to fail to qualify as a
REMIC or (ii) result in the imposition of a tax upon any Trust REMIC or the Trust (including but not limited to the tax on “prohibited
transactions” as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section
860G(d) of the Code, but not including the tax on “net income from foreclosure property”) (either such event, an “Adverse
REMIC Event”) unless the Certificate Administrator receives an Opinion of Counsel (at the expense of the party seeking
to take such action or, if such party fails to pay such expense, and the Certificate Administrator determines that taking such
action is in the best interest of the Trust and the Certificateholders, at the expense of the

 

     -395-

     

    

 

Trust,
but in no event at the expense of the Certificate Administrator or the Trustee) to the effect that the contemplated action will
not, with respect to the Trust, any Trust REMIC created hereunder, cause the loss of such status or, unless the Certificate Administrator
determines in its sole discretion to indemnify the Trust against such tax, result in the imposition of such a tax (not including
a tax on “net income from foreclosure property”). The Trustee shall not take or fail to take any action (whether or
not authorized hereunder) as to which the Certificate Administrator has advised it in writing that it has received an Opinion
of Counsel to the effect that an Adverse REMIC Event could occur with respect to such action. The Certificate Administrator may
consult with counsel to make such written advice, and the cost of same shall be borne by the party seeking to take the action
not expressly permitted by this Agreement, but in no event at the expense of the Certificate Administrator or the Trustee. At
all times as may be required by the Code, the Certificate Administrator will to the extent within its control and the scope of
its duties more specifically set forth herein, maintain substantially all of the assets of each Trust REMIC as “qualified
mortgages” as defined in Section 860G(a)(3) of the Code and “permitted investments” as defined in Section 860G(a)(5)
of the Code.

 

(g)          In
the event that any applicable federal, state or local tax, including interest, penalties or assessments, additional amounts or
additions to tax, is imposed on any Trust REMIC, such tax shall be charged against amounts otherwise distributable to the Holders
of the Certificates, except as provided in the last sentence of this Section 10.01(g); provided that with respect
to the estimated amount of tax imposed on any “net income from foreclosure property” pursuant to Section 860G(c) of
the Code or any similar tax imposed by a state or local tax authority, the Special Servicer shall retain in the related REO Account
a reserve for the payment of such taxes in such amounts and at such times as it shall deem appropriate (or as advised by the Certificate
Administrator in writing), and shall remit to the Master Servicer such reserved amounts as the Master Servicer shall request in
order to pay such taxes. Except as provided in the preceding sentence, the Master Servicer shall withdraw from the Collection
Account sufficient funds to pay or provide for the payment of, and to actually pay, such tax as is estimated to be legally owed
by any Trust REMIC (but such authorization shall not prevent the Certificate Administrator from contesting, at the expense of
the Trust (other than as a consequence of a breach of its obligations under this Agreement), any such tax in appropriate proceedings,
and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The Certificate Administrator
is hereby authorized to and shall segregate, into a separate non-interest bearing account, the net income from any “prohibited
transaction” under Section 860F(a) of the Code or the amount of any taxable contribution to any Trust REMIC after the Startup
Day that is subject to tax under Section 860G(d) of the Code and use such income or amount, to the extent necessary, to pay such
prohibited transactions tax. To the extent that any such tax (other than any such tax paid in respect of “net income from
foreclosure property”) is paid to the Internal Revenue Service or applicable state or local tax authorities, the Certificate
Administrator shall retain an equal amount from future amounts otherwise distributable to the Holders of Class R Certificates
(as applicable) and shall distribute such retained amounts, (x) in the case of the Lower-Tier Regular Interests, to the Upper-Tier
REMIC to the extent they are fully reimbursed for any Realized Losses or Retained Certificate Realized Losses, as applicable,
arising therefrom and then to the Holders of the Class R Certificates in respect of the Class LR Interest in the manner specified
in Section 4.01(c) and (y) in the case of the Upper-Tier REMIC, to the Holders of the Principal Balance Certificates in
the manner specified in Section 4.01(a) or Section 4.01(b), as applicable, to the extent they are fully reimbursed
for any Realized Losses or

 

     -396-

     

    

 

Retained
Certificate Realized Losses, as applicable, arising therefrom and then to the Holders of the Class R Certificates in respect of
the Class UR Interest. None of the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer shall be
responsible for any taxes imposed on any Trust REMIC except to the extent such taxes arise as a consequence of a breach of their
respective obligations under this Agreement which breach constitutes willful misconduct, bad faith, or negligence by such party.

 

(h)          The
Certificate Administrator shall, for federal income tax purposes, maintain or cause to be maintained books and records with respect
to each Trust REMIC on a calendar year and on an accrual basis or as otherwise may be required by the REMIC Provisions.

 

(i)           Following
the Startup Day, neither the Certificate Administrator nor the Trustee shall accept any contributions of assets to any Trust REMIC
unless the Certificate Administrator and the Trustee shall have received an Opinion of Counsel (at the expense of the party seeking
to make such contribution) to the effect that the inclusion of such assets in such Trust REMIC will not cause an Adverse REMIC
Event.

 

(j)           Neither
the Certificate Administrator nor the Trustee shall enter into any arrangement by which the Trust or any Trust REMIC will receive
a fee or other compensation for services nor permit the Trust or any Trust REMIC to receive any income from assets other than
“qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined
in Section 860G(a)(5) of the Code.

 

(k)          Solely
for the purposes of Treasury Regulations Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” by which
the Certificate Balance or Notional Amount of each Class of Regular Certificates and by which the Lower-Tier Principal Amount
of each Class of Lower-Tier Regular Interests would be reduced to zero is the date that is the Rated Final Distribution Date.

 

(l)           None
of the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable, shall sell, dispose
of or substitute for any of the Mortgage Loans (except in connection with (i) the default, imminent default or foreclosure of
a Mortgage Loan, including but not limited to, the acquisition or sale of a Mortgaged Property acquired by foreclosure or deed
in lieu of foreclosure, (ii) the bankruptcy of the Trust, (iii) the termination of the Trust pursuant to Article IX of
this Agreement or (iv) a purchase of Mortgage Loans pursuant to Article II or Article III of this Agreement) or
acquire any assets for the Trust or any Trust REMIC or sell or dispose of any investments in the Collection Account or the REO
Account for gain unless it has received an Opinion of Counsel that such sale, disposition or substitution will not (a) affect
adversely the status of any Trust REMIC as a REMIC or (b) unless the Trustee, the Certificate Administrator, the Master Servicer
or the Special Servicer, as the case may be, has determined in its sole discretion to indemnify the Trust against such tax, cause
the Trust or any Trust REMIC to be subject to a tax on “prohibited transactions” pursuant to the REMIC Provisions.

 

(m)         The
Certificate Administrator’s authority under this Agreement includes the authority to make, and the Certificate Administrator
is hereby directed to make, any elections allowed under the Code (i) to avoid the application of Section 6221 of the Code (or
successor

 

     -397-

     

    

 

provisions)
to either Trust REMIC and (ii) to avoid payment by either Trust REMIC under Section 6225 of the Code (or successor provisions)
of any tax, penalty, interest or other amount imposed under the Code that would otherwise be imposed on any Holder of a Class
R Certificate, past or present. Each Holder of a Class R Certificate agrees, by acquiring such Certificate, to any such elections.

Person into which any REMIC Administrator may be merged or converted or with which it may be consolidated, or any Person resulting

EXCHANGE ACT REPORTING AND REGULATION AB COMPLIANCE

 

Section
11.01   Intent of the Parties; Reasonableness. The parties hereto acknowledge and agree that the purpose
of Article XI of this Agreement is to facilitate compliance by the Depositor (and any Other Depositor of any Other
Securitization that includes a Serviced Companion Loan) with the provisions of Regulation AB and the related rules and
regulations of the Commission. The Depositor shall not exercise its rights to request delivery of information or other
performance under these provisions other than in reasonable good faith, or for purposes other than compliance with the
Securities Act, the Exchange Act, the Sarbanes-Oxley Act and, in each case, the rules and regulations of the Commission
thereunder. The parties hereto acknowledge that interpretations of the requirements of Regulation AB may change over time,
due to interpretive guidance provided by the Commission or its staff, and agree to comply with requests made by the Depositor
(or any Other Depositor or Other Trustee of any Other Securitization that includes a Serviced Companion Loan) in good faith
for delivery of information under these provisions on the basis of such evolving interpretations of Regulation AB (to the
extent such interpretations require compliance and are not “grandfathered”). In connection with BANK 2017-BNK4,
Commercial Mortgage Pass-Through Certificates, Series 2017-BNK4, and any Other Securitization subject to Regulation AB that

 

     -399-

     

    

 

includes
a Serviced Companion Loan, each of the Master Servicer, the Special Servicer, the Operating Advisor, the Trustee, the Custodian
and the Certificate Administrator shall cooperate fully with the Depositor and the Certificate Administrator, and any Other Depositor,
Other Trustee and Other Certificate Administrator of any Other Securitization that includes a Serviced Companion Loan, as applicable,
to deliver or make available to the Depositor or the Certificate Administrator, and any such Other Depositor, Other Trustee or
Other Certificate Administrator, as applicable (including any of its assignees or designees), any and all statements, reports,
certifications, records and any other information (in its possession or reasonably attainable) necessary in the reasonable good
faith determination of the Depositor or such Other Depositor, as applicable, to permit the Depositor or such Other Depositor,
as applicable, to comply with the provisions of Regulation AB, together with such disclosures relating to the Master Servicer,
the Special Servicer, the Operating Advisor, the Trustee, the Custodian, the Asset Representations Reviewer and the Certificate
Administrator, as applicable, and any Sub-Servicer, or the servicing of the Mortgage Loans (and the related Serviced Companion
Loan, if applicable), reasonably believed by the Depositor or the related Other Depositor to be necessary in order to effect such
compliance. Each party to this Agreement shall have a reasonable period of time to comply with any written request made under
this Section 11.01, but in any event, shall, upon reasonable advance written request, provide information in sufficient
time to allow the Depositor and each Other Depositor to satisfy any related filing requirements. For purposes of this Article
XI, to the extent any party has an obligation to exercise commercially reasonable efforts to cause a third party to perform,
such party hereunder shall not be required to bring any 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 servicer as contemplated by Item 1108(a)(2)) as
servicer or sub-servicer or succession to the Certificate Administrator under this Agreement by any Person (i) into which the
Master Servicer and the Special Servicer, such Sub Servicer or Certificate Administrator may be merged or consolidated, or
(ii) which may be appointed as a successor to the Master Servicer and the Special Servicer or to any such Sub-Servicer or
Certificate Administrator, the person removing and replacing the Master Servicer and the Special Servicer or Certificate
Administrator shall provide to the Depositor, the Master Servicer, the Special Servicer, the Certificate Administrator and
each Other Depositor, as applicable, at least fifteen (15) calendar days prior to the effective date of such succession or
appointment (or such shorter period as is agreed to by the Depositor), (x) written notice to the Depositor, the Other
Depositor and the Other Certificate Administrator of such succession or appointment and (y) in writing and in form and
substance reasonably satisfactory to the Depositor, all information relating to such successor reasonably requested by the
Depositor, Other Depositor or Other Certificate Administrator in order to comply with its reporting obligation under Item
6.02 of Form 8-K pursuant to the Exchange Act (if such reports under the Exchange Act are required to be filed under the
Exchange Act); provided, however that if disclosing such information prior to such effective date would violate
any applicable law or confidentiality agreement, the Master Servicer, the Special Servicer, any Additional Servicer or the
Certificate Administrator, as the case may be, shall submit such disclosure to the Depositor and the Other Depositor no later
than the effective date of such succession or appointment.

 

     -400-

     

    

 

(b)          Each
of the Master Servicer, the Special Servicer, the Sub-Servicer, the Trustee, the Operating Advisor and the Certificate Administrator
(each of the Master Servicer, the Special Servicer, the Trustee, the Operating Advisor and the Certificate Administrator and each
Sub-Servicer, for purposes of this Section 11.02, a “Servicer”) is permitted to utilize one or more
Subcontractors to perform certain of its obligations hereunder. If such Subcontractor will be a Servicing Function Participant,
such Servicer shall promptly upon written request provide to the Depositor or any Mortgage Loan Seller (and any Other Trustee,
Other Certificate Administrator and Other Depositor related to any Other Securitization that includes a related Serviced Companion
Loan) a written description (in form and substance satisfactory to the Depositor, such Mortgage Loan Seller or such Other Trustee,
Other Certificate Administrator or Other Depositor, as applicable) of the role and function of each Subcontractor utilized by
such Servicer, specifying (i) the identity of such Subcontractor and (ii) the elements of the Servicing Criteria that will be
addressed in assessments of compliance provided by each such Subcontractor. As a condition to the utilization by such Servicer
of any Subcontractor determined to be a Servicing Function Participant, such Servicer shall (i) with respect to any such Subcontractor
engaged by such Servicer that is an Initial Sub-Servicer, use commercially reasonable efforts to cause, and (ii) with respect
to any other subcontractor with which it has entered into a servicing relationship, cause such Subcontractor used by such Servicer
for the benefit of the Depositor and the Trustee (and any Other Trustee, Other Certificate Administrator and Other Depositor related
to any Other Securitization that includes a related Serviced Companion Loan) to comply with the provisions of Section 11.10
and Section 11.11 of this Agreement to the same extent as if such Subcontractor were such Servicer. With respect to
any Servicing Function Participant engaged by such Servicer that is an Initial Sub-Servicer, such Servicer shall be responsible
for using commercially reasonable efforts to obtain, and with respect to each other Servicing Function Participant engaged by
such Servicer, such Servicer shall obtain from each such Servicing Function Participant and deliver to the applicable Persons
any assessment of compliance report and related accountant’s attestation required to be delivered by such Subcontractor
under Section 11.10 and Section 11.11, in each case, as and when required to be delivered. For the avoidance of
doubt, the Custodian shall not be permitted to utilize any Subcontractor to perform any of its obligations hereunder.

 

(c)          Notwithstanding
the foregoing, if a Servicer engages a Subcontractor, other than an Initial Sub-Servicer in connection with the performance of
any of its duties under this Agreement, such Servicer shall be responsible for determining whether such Subcontractor is a “servicer”
within the meaning of Item 1101 of Regulation AB and whether any such Subcontractor meets the criteria in Item 1108(a)(2)(i),
(ii) or (iii) of Regulation AB. If a Servicer determines, pursuant to the preceding sentence, that such Subcontractor is a “servicer”
within the meaning of Item 1101 of Regulation AB and meets the criteria in Item 1108(a)(2)(i), (ii) or (iii) of Regulation AB,
then such Subcontractor shall be deemed to be a Sub-Servicer for purposes of this Agreement, the engagement of such Sub-Servicer
shall not be effective unless and until notice is given to the Depositor and the Certificate Administrator of any such Sub-Servicer
and Sub-Servicing Agreement. Other than with respect to the Initial Sub-Servicer, no Sub-Servicing Agreement shall be effective
until fifteen (15) days after such written notice is received by the Depositor and the Certificate Administrator (or such shorter
period as is agreed to by the Depositor). Such notice shall contain all information reasonably necessary to enable the Certificate
Administrator to accurately and timely report the event under Item 6.02 of Form 8-K

 

     -401-

     

    

 

pursuant
to the Exchange Act (if such reports under the Exchange Act are required to be filed under the Exchange Act).

 

(d)          In
connection with the succession to the Trustee under this Agreement by any Person (i) into which the Trustee may be merged or consolidated,
or (ii) which may be appointed as a successor to the Trustee, the Trustee shall deliver written notice to the Depositor, the Certificate
Administrator and the 17g-5 Information Provider, which shall promptly post such notice to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c), in each case at least thirty (30) calendar days prior to the effective date of such
succession or appointment (or if such prior notice is violative of applicable law or any applicable confidentiality agreement,
no later than one (1) Business Day after such effective date of succession) and shall furnish to the Depositor and the Certificate
Administrator, in writing and in form and substance reasonably satisfactory to the Depositor and the Certificate Administrator,
all information reasonably necessary for the Certificate Administrator to accurately and timely report, pursuant to Section
11.07, the event under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports under the Exchange Act are required
to be filed under the Exchange Act).

 

(e)           Notwithstanding
anything to the contrary contained in this Article XI, in connection with any Sub-Servicer and/or any Mortgage Loan that
is the subject of an Initial Sub-Servicing Agreement, with respect to all matters related to Regulation AB, the Master Servicer
shall not have any obligation other than to use commercially reasonable efforts to cause such Sub-Servicer to comply with its
obligations under such Initial Sub-Servicing Agreement.

 

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

 

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 of this Agreement, the Certificate Administrator shall prepare
for execution by the Depositor any Forms 8-K, 10-D, ABS-EE and 10-K required by the Exchange Act, in order to permit the
timely filing thereof, and the Certificate Administrator shall file (via the Commission’s Electronic Data Gathering
and Retrieval System (“EDGAR”)) such Forms executed by the Depositor.

 

Each
party hereto shall be entitled to rely on the information in the Prospectus or this Agreement with respect to the identity of
any “sponsor”, credit enhancer, derivative provider or “significant obligor” as of the Closing Date other
than with respect to itself or any information required to be provided by it or indemnified for by it pursuant to any separate
agreement.

 

(b)          In
the event that the Certificate Administrator is unable to timely file with the Commission all or any required portion of any Form
8-K, 10-D, ABS-EE or 10-K required to be filed by this Agreement because required disclosure information was either not delivered
to it

 

     -402-

     

    

 

or
delivered to it after the delivery deadlines set forth in this Agreement, the Certificate Administrator will promptly notify the
Depositor. In the case of Forms 10-D, ABS-EE and 10-K, the Depositor, the Master Servicer, the Certificate Administrator, the
Operating Advisor and the Trustee will thereupon cooperate to prepare and file a Form 12b-25 and a Form 10-D/A, Form ABS-EE/A
or Form 10-K/A, as applicable, pursuant to Rule 12b-25 of the Exchange Act. In the case of Form 8-K, the Certificate Administrator
will, upon receipt of all required Form 8-K Disclosure Information and upon the approval and direction of the Depositor, include
such disclosure information on the next succeeding Form 10-D to be filed for the Trust. In the event that any previously filed
Form 8-K, Form 10-D, Form ABS-EE or Form 10-K needs to be amended, the Certificate Administrator will notify the Depositor, and
such other parties as needed and the parties hereto will cooperate with the Certificate Administrator to prepare any necessary
Form 8-K/A, Form 10-D/A, Form ABS-EE/A or Form 10-K/A. Any Form 15, Form 12b-25 or any amendment to Form 8-K, Form 10-D, Form
ABS-EE or Form 10-K shall be signed by an officer of the Depositor. The parties to this Agreement acknowledge that the performance
by the Certificate Administrator of its duties under this Section 11.03 related to the timely preparation and filing of
Form 15, a Form 12b-25 or any amendment to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K is contingent upon the parties observing
all applicable deadlines in the performance of their duties under Sections 11.03, 11.04, 11.05, 11.06,
11.07, 11.08, 11.09, 11.10, 11.11 and 11.15 of this Agreement. The Certificate Administrator
shall have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare,
arrange for execution and/or timely file any such Form 15, Form 12b-25 or any amendments to Form 8-K, Form 10-D, Form ABS-EE or
Form 10-K, where such failure results from the Certificate Administrator’s inability or failure to receive, on a timely
basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 15, Form 12b-25
or any amendments to Forms 8-K, Form 10-D, Form ABS-EE or Form 10-K, not resulting from its own negligence, bad faith or willful
misconduct.

Servicer or Servicing Function Participant engaged or utilized, as applicable, by any such parties) observing all applicable deadlines

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

Companion Loan or a party that services, specially services or is trustee or custodian for a Serviced Companion Loan) in the same
time frame as set forth in this Section 11.05.

 

Section
11.06   Sarbanes-Oxley Certification. Each Form 10-K shall include a Sarbanes-Oxley Certification in the form

Special Servicer, the Trustee, the Certificate Administrator, the Custodian, the Operating Advisor and the Asset Representations
Reviewer (in the case of the Asset Representations Reviewer, solely with respect to reporting periods in which the Asset Representations
Reviewer is required to deliver an Asset Review Report) shall provide, and (i) with respect to each Initial Sub-Servicer engaged
by the Master Servicer or the Special Servicer, as the case may be, that is a Servicing Function Participant shall use commercially
reasonable efforts to cause such Initial Sub-Servicer to provide, and (ii) with respect to each other Servicing Function Participant
with which the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Custodian or the Operating
Advisor has entered into a servicing relationship with respect to the Mortgage Loans, shall cause such Servicing Function Participant
to provide, to each Person who signs the Sarbanes-Oxley Certification for the Trust or any Other Securitization that includes
a Serviced Companion Loan (individually and collectively, the “Certifying Person”), on or before March 1st
of each year commencing in March 2018, a certification substantially in the form attached hereto as Exhibits Y-1, Y-2,
Y-3, Y-4, Y-5, Y-6 or Y-7 (each, a “Performance Certification”), as applicable,
on which each Certifying Person, the entity for which such Certifying Person acts as an officer (if the Certifying Person is an
individual), and such entity’s officers, directors and Affiliates (collectively with the Certifying Person, “Certification
Parties”) can reasonably rely; provided that, if a Servicing Function Participant (other than an Initial Sub-Servicer)
with which the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Custodian or the Operating
Advisor has entered into a servicing relationship with respect to the Mortgage Loans fails to provide a Performance Certification,
the Performance Certification provided by the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator,
the Custodian or the Operating Advisor, as applicable, that engaged such Servicing Function Participant shall not exclude information

is deposited into a commercial mortgage securitization (including an “Other Securitization”) and the Reporting
Servicer is provided with timely and complete contact information for the parties to such Other Securitization, each Reporting
Servicer, upon not less than thirty (30) days prior written request, shall provide to the Person who signs the Sarbanes-Oxley
Certification with respect to such Other Securitization either the Performance Certification or a separate certification in form

(ii) annual report on assessment of compliance with servicing criteria provided pursuant to Section 11.10 and (iii) accountant’s
report provided pursuant to Section 11.11, and shall include a certification that each such annual compliance statement
or report discloses any deficiencies or defaults described to the registered public accountants of such Reporting Servicer to
enable such accountants to render the certificates provided for in Section 11.11. In the event any Reporting Servicer is
terminated or resigns pursuant to the terms of this Agreement, or any applicable sub-servicing agreement or primary servicing
agreement, as the case may be, such Reporting Servicer shall provide a certification to each affected Certifying Person pursuant
to this Section 11.06 with respect to the period of time it was subject to this Agreement or the applicable sub-servicing
or primary servicing agreement, as the case may be. Each such Performance Certification shall be provided in EDGAR-Compatible
Format, or in such other format agreed upon by the Depositor, the Certificate Administrator, any affected Other Depositor and
Other Certificate Administrator and such providing parties. Notwithstanding the foregoing, nothing in this Section 11.06
shall require any Reporting Servicer (i) to certify or verify the accurateness or completeness of any information provided to
such Reporting Servicer by third parties (including a “significant obligor”, but other than an Additional Servicer
or a Sub-Servicer appointed pursuant to Section 3.20), (ii) to certify information other than to such Reporting Servicer’s
knowledge and in accordance with such Reporting Servicer’s responsibilities hereunder or (iii) with respect to completeness
of information and reports, to certify anything other than that all fields of information called for in written reports prepared

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 permitted transferee)
information about itself that such Mortgage Loan Seller reasonably requires to meet the requirements of Items 1117 and 1119

reasonable advance notice (and, in any event, not less than ten (10) Business Days) of the exercise of its rights hereunder and

of Regulation AB) (together with notification of the relevant Distribution Date) with respect to an Other Securitization that
includes such Serviced Companion Loan, to the extent that the Master Servicer or the Special Servicer, as the case may be, is
in receipt of the updated financial statements of such “significant obligor” for any calendar quarter (other than
the fourth (4th) calendar quarter of any calendar year) from the Mortgagor, beginning with the first calendar quarter in which
such notice from the Other Depositor was received, or the updated financial statements of such “significant obligor”
for any calendar year, beginning for the calendar year in which such notice from the Other Depositor was received, as applicable,

and provided by the Special Servicer to the Master Servicer).

 

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

into after receipt of written notice from the Other Depositor that such

 

     -426-

     

    

 

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 such financial information. The Master Servicer (in the case of Non-Specially Serviced Loans) or the Special
Servicer (in the case of Specially Serviced Loans) shall use efforts consistent with the Servicing Standard (taking into account,
in addition, the ongoing reporting obligations of such Other Depositor under the Exchange Act) to obtain the periodic financial
statements required to be delivered by the related Mortgagor under the related Mortgage Loan documents.

 

The
Master Servicer (with respect to Non-Specially Serviced Loans) and the Special Servicer (with respect to Specially Serviced Loans)
shall (and shall cause each applicable Sub-Servicing Agreement entered into after receipt of written notice from the Other Depositor
that such Serviced 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 with respect to the Other Securitization, shall forward an Officer’s Certificate
evidencing its attempts to obtain this information to the Other Exchange Act Reporting Party and Other Depositor related to such
Other Securitization; provided, however, the Special Servicer shall provide such Officer’s Certificate to
the Master Servicer and the Master Servicer shall forward such Officer’s Certificate to the Other Exchange Act Reporting
Party and Other Depositor related to such Other Securitization. This Officer’s Certificate should be addressed to the certificate
administrator at its corporate trust office, as specified in the related Other Pooling and Servicing Agreement.

 

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

 

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

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

Section
12.01   Asset Review.

 

(a)          On
or prior to each Distribution Date, based either on the CREFC® Delinquent Loan Status Report and/or the CREFC®
Loan Periodic Update File delivered by the Master Servicer for such Distribution Date, the Certificate Administrator shall
determine if an Asset Review Trigger has occurred. If an Asset Review Trigger is determined to have occurred, the Certificate
Administrator shall promptly provide notice to all Certificateholders and each other party to this Agreement. Any notice required
to be delivered to the Certificateholders pursuant to this Article XII shall be delivered by the Certificate Administrator
by posting such notice on the Certificate Administrator’s Website, by mailing such notice to the Certificateholders’
addresses appearing in the Certificate Register in the case of Definitive Certificates and by delivering such notice via the Depository
in the case of Book-Entry Certificates. The Certificate Administrator shall include in the Form 10-D relating to the reporting
period in which the Asset Review Trigger occurred the following statement describing the events that caused the Asset Review Trigger
to occur: “As of the [Date of Distribution], the following Mortgage Loans identified below are sixty (60) or more days delinquent
and an Asset Review Trigger as defined in the Pooling and Servicing Agreement has occurred.”. On each Distribution Date
occurring after providing such notice to Certificateholders, the Certificate Administrator, based on information provided to it
by the Master Servicer or the Special Servicer, as the case may be, shall determine whether (1) any additional Mortgage Loan has
become a Delinquent Loan, (2) any Mortgage Loan has ceased to be a Delinquent Loan and (3) whether an Asset Review Trigger has
ceased to exist, and, if there is an occurrence of any of the events or circumstances identified in clauses (1), (2)
and/or (3), deliver such information in a written notice (which may be via email) in the form of Exhibit RR
within two (2) Business Days to the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations
Reviewer.

 

If
Certificateholders (other than Holders of the RR Interest) evidencing not less than 5% of the Voting Rights of the Certificates
deliver to the Certificate Administrator, within ninety (90) days after the filing of the Form 10-D reporting the occurrence of
an Asset Review Trigger, a written direction requesting a vote to commence an Asset Review (an “Asset Review Vote Election”),
then the Certificate Administrator shall promptly provide written notice thereof to all Certificateholders (with a copy to the
Asset Representations Reviewer) and conduct a solicitation of votes in accordance with Section 5.10 to authorize an Asset
Review. Upon the affirmative vote to authorize an Asset Review by Holders of Certificates evidencing at least (i) a majority of
those Certificateholders who cast votes and (ii) a majority of an Asset Review Quorum within one hundred fifty (150) days of receipt
of the Asset Review Vote Election (an “Affirmative Asset Review Vote”), the Certificate Administrator shall
promptly provide written

 

     -428-

     

    

 

notice
thereof to all parties to this Agreement, the Underwriters, the Mortgage Loan Sellers, the Directing Certificateholder, the Risk
Retention Consultation Party and the other Certificateholders (the “Asset Review Notice”). Upon receipt of
an Asset Review Notice, the Asset Representations Reviewer shall request access to the Secure Data Room by providing the Certificate
Administrator with a certification substantially in the form attached hereto as Exhibit QQ (which shall be sent via email
to trustadministrationgroup@wellsfargo.com or submitted electronically via the Certificate Administrator’s Website). Upon
receipt of such certification, the Certificate Administrator shall promptly (and in any case within two (2) Business Days after
such receipt) grant the Asset Representations Reviewer access to the Secure Data Room. In the event an Affirmative Asset Review
Vote has not occurred within such one hundred fifty (150) day period following the receipt of the Asset Review Vote Election,
no Certificateholder may request a vote or cast a vote for an Asset Review and the Asset Representations Reviewer will not be
required to review any Delinquent Loan unless and until (A) an additional Mortgage Loan has become a Delinquent Loan after the
expiration of such one hundred fifty (150) day period, (B) a new Asset Review Trigger has occurred as a result or an Asset Review
Trigger is otherwise in effect, (C) the Certificate Administrator has timely received any Asset Review Vote Election after the
occurrence of the events described in clauses (A) and (B) in this sentence and (D) an Affirmative Asset Review Vote
has occurred within one hundred fifty (150) days after the Asset Review Vote Election described in clause (C) in this sentence.
After the occurrence of any Asset Review Vote Election or an Affirmative Asset Review Vote, no Certificateholder may make any
additional Asset Review Vote Election except as described in the immediately preceding sentence. Any reasonable out-of-pocket
expenses incurred by the Certificate Administrator in connection with administering such vote will be paid as an expense of the
Trust from the Collection Account. The Certificate Administrator shall be entitled to administer any vote in connection with the
foregoing through an agent.

 

(b)          (i)
Upon receipt of an Asset Review Notice, the Custodian (with respect to clauses (1) - (5) below for all Mortgage
Loans), the Master Servicer (with respect to clause (6) below for Non-Specially Serviced Loans) and the Special Servicer
(with respect to clause (6) below for Specially Serviced Loans), in each case to the extent in such party’s possession,
shall promptly, but in no event later than ten (10) Business Days, provide the following materials in electronic format to the
Asset Representations Reviewer (collectively, with the Diligence Files posted on the Secure Data Room by the Certificate Administrator
pursuant to Section 4.08, a copy of the Prospectus, a copy of each related Mortgage Loan Purchase Agreement and a copy
of this Agreement, the “Review Materials”):

 

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

 

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

 

     -429-

     

    

 

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

 

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

 

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

 

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

 

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

 

(iii)          The
Asset Representations Reviewer may, but is under no obligation to, consider and rely upon information furnished to it by a Person
that is not a party to this Agreement or the applicable Mortgage Loan Seller, and shall do so only if such information can be
independently verified (without unreasonable effort or expense to the Asset Representations Reviewer) and is determined by the
Asset Representations

 

     -430-

     

    

 

Reviewer in its good faith and sole discretion to be relevant to the Asset Review conducted pursuant to
this Section 12.01 (any such information, “Unsolicited Information”).

 

(iv)          Upon
receipt by the Asset Representations Reviewer of the Asset Review Notice and access to the Diligence File with respect to a Delinquent
Loan, the Asset Representations Reviewer, as an independent contractor, shall commence a review of the compliance of each Delinquent
Loan with the representations and warranties related to that Delinquent Loan (such review, the “Asset Review”).
The Asset Representations Reviewer shall perform an Asset Review with respect to each representation and warranty made by the
related Mortgage Loan Seller with respect to such Delinquent Loan in accordance with the procedures set forth on Exhibit PP
(each such procedure, a “Test”); provided, however, the Asset Representations Reviewer may, but
is under no obligation to, modify any Test and/or associated Review Materials described in Exhibit PP if, and only to the
extent, the Asset Representations Reviewer determines pursuant to the Asset Review Standard that it is necessary to modify such
Test and/or such associated Review Materials in order to facilitate its Asset Review in accordance with the Asset Review Standard.
Once an Asset Review of a Mortgage Loan is completed, no further Asset Review shall be required in respect of, or performed on,
such Mortgage Loan notwithstanding that such Mortgage Loan may continue to be a Delinquent Loan or again become a Delinquent Loan
at a time when a new Asset Review Trigger occurs and a new Affirmative Asset Review Vote is obtained subsequent to the occurrence
of such new Asset Review Trigger.

 

(v)           No
Certificateholder shall have the right to change the scope of the Asset Review, and the Asset Representations Reviewer shall not
be required to review any information other than (1) the Review Materials and (2) if applicable, Unsolicited Information.

 

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

 

(vii)         The
Asset Representations Reviewer shall prepare a preliminary report with respect to each Delinquent Loan within fifty-six (56) days
after the date on which access to the Secure Data Room is provided. In the event that the Asset Representations Reviewer determines
that the Review Materials are insufficient to complete a Test and such missing documentation is not delivered to the Asset Representations
Reviewer by the related Mortgage Loan Seller, the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special
Servicer (with respect to Specially Serviced Loans) to the extent in the Master Servicer’s or the Special Servicer’s
possession within ten (10) Business Days following the request by the Asset Representations Reviewer to the Master Servicer, the
Special Servicer or the related Mortgage Loan Seller, as the case may be, as described in Section 12.01(b)(ii), the Asset
Representations Reviewer shall list such missing documents in such preliminary report setting forth the preliminary results of
the application of the Tests and the reasons why such missing documents are

 

     -431-

     

    

 

necessary to complete a Test and (if the Asset Representations
Reviewer has so concluded) that the absence of such documents will be deemed to be a failure of such Test. The Asset Representations
Reviewer shall provide such preliminary report to the Master Servicer (only with respect to Non-Specially Serviced Loans), the
Special Servicer (with respect to Specially Serviced Loans) and the related Mortgage Loan Seller. If the preliminary report indicates
that any of the representations and warranties fails or is deemed to fail any Test, the related Mortgage Loan Seller shall have
ninety (90) days (the “Cure/Contest Period”) to remedy or otherwise refute the failure. Any documents or explanations
to support the related Mortgage Loan Seller’s claim that the representation and warranty has not failed a Test or that any
missing information or documents in the Review Materials are not required to complete a Test shall be sent by such Mortgage Loan
Seller to the Asset Representations Reviewer. For avoidance of doubt, the Asset Representations Reviewer shall not be required
to prepare a preliminary report in the event the Asset Representations Reviewer determines that there is no Test failure with
respect to the related Mortgage Loan.

 

(viii)          The
Asset Representations Reviewer shall, within sixty (60) days after the date on which access to the Secure Data Room is provided
to the Asset Representations Reviewer by the Certificate Administrator or within the ten (10) days after the expiration of the
Cure/Contest Period (whichever is later), complete an Asset Review with respect to each Delinquent Loan and deliver (i) a report
setting forth the Asset Representations Reviewer’s findings and conclusions as to whether or not it has determined there
is any evidence of a failure of any Test based on the Asset Review and a statement that the Asset Representations Reviewer’s
findings and conclusions set forth in such report were not influenced by any third party (an “Asset Review Report”)
to each party to this Agreement, the related Mortgage Loan Seller for each Delinquent Loan, the Directing Certificateholder and
(ii) a summary of the Asset Representations Reviewer’s conclusions included in such Asset Review Report (an “Asset
Review Report Summary”) to the Trustee and the Certificate Administrator. The period of time by which the Asset Review
Report must be completed and delivered may be extended by up to an additional thirty (30) days, upon written notice to the parties
to this Agreement and the applicable Mortgage Loan Seller, if the Asset Representations Reviewer determines pursuant to the Asset
Review Standard that such additional time is required due to the characteristics of the Mortgage Loan and/or the Mortgaged Property
or Mortgaged Properties. In no event may the Asset Representations Reviewer determine whether any Test failure constitutes a Material
Defect, or whether the Trust should enforce any rights it may have against the applicable Mortgage Loan Seller, which, in each
case, shall be a responsibility of the applicable Enforcing Servicer pursuant to Section 2.03(k) of this Agreement.

 

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

 

     -432-

     

    

 

responsibility to independently obtain any such documentation from any party to this Agreement or otherwise.

 

(x)          Within
thirty (30) days after receipt of an Asset Review Report with respect to any Mortgage Loan, the Special Servicer shall determine,
based on the Servicing Standard, there exists a Material Defect with respect to such Mortgage Loan. If the Special Servicer determines
that a Material Defect exists, the Special Servicer shall enforce the obligations of the applicable Mortgage Loan Seller with
respect to such Material Defect in accordance with Section 2.03(b).

 

(c)          The
Asset Representations Reviewer and its affiliates shall keep confidential any information appropriately labeled as “Privileged
Information” received from any party to this Agreement or any Sponsor (including, without limitation, in connection with
the review of the Mortgage Loans) and not disclose such Privileged Information to any Person (including Certificateholders), other
than (1) to the extent expressly required by this Agreement in an Asset Review Report or otherwise, to the other parties to this
Agreement with a notice indicating that such information is Privileged Information or (2) pursuant to a Privileged Information
Exception. Each party to this Agreement that receives Privileged Information from the Asset Representations Reviewer with a notice
stating that such information is Privileged Information shall not disclose such Privileged Information to any Person without the
prior written consent of the Special Servicer other than pursuant to a Privileged Information Exception.

 

(d)          The
Asset Representations Reviewer may delegate its duties to agents or subcontractors so long as the related agreements or arrangements
with such agents or subcontractors are consistent with the provisions of this Section 12.01; provided that no agent
or subcontractor may (i) be affiliated with any Mortgage Loan Seller, the Master Servicer, the Special Servicer, the Depositor,
the Certificate Administrator, the Trustee, the Directing Certificateholder or any of their respective Affiliates or (ii) have
been paid any fees, compensation or other remuneration by an Underwriter, the Master Servicer, the Special Servicer, the Depositor,
the Certificate Administrator, the Trustee, the Directing Certificateholder or any of their respective Affiliates in connection
with due diligence or other services with respect to any Mortgage Loan prior to the Closing Date. Notwithstanding the foregoing
sentence, the Asset Representations Reviewer shall remain obligated and primarily liable for any Asset Review required hereunder
in accordance with the provisions of this Agreement without diminution of such obligation or liability or related obligation or
liability by virtue of such delegation or arrangements or by virtue of indemnification from any Person acting as its agents or
subcontractor to the same extent and under the same terms and conditions as if the Asset Representations Reviewer alone were performing
its obligations under this Agreement. The Asset Representations Reviewer shall be entitled to enter into an agreement with any
agent or subcontractor providing for indemnification of the Asset Representations Reviewer by such agent or subcontractor, and
nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

 

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

 

     -433-

     

    

 

(a)          The
Asset Representations Reviewer shall be paid a fee of $5,000 (the “Asset Representations Reviewer Upfront Fee”)
on the Closing Date. As compensation for the performance of its routine duties, the Asset Representations Reviewer shall be paid
a fee (the “Asset Representations Reviewer Fee”), payable monthly from amounts received in respect of the Mortgage
Loans and shall be equal to the product of a rate equal to 0.00028% per annum (the “Asset Representations Reviewer
Fee Rate”) and the Stated Principal Balance of the Mortgage Loans and any REO Loans (including any Non-Serviced Mortgage
Loan, but not any Companion Loan) and shall be calculated in the same manner as interest is calculated on such Mortgage Loans.

 

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

 

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

 

     -434-

     

    

 

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

 

Section

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

 

The
Asset Representations Reviewer shall at all times be an Eligible Asset Representations Reviewer and if the Asset Representations
Reviewer ceases to be an Eligible Asset Representations Reviewer, the Asset Representations Reviewer shall immediately notify

 

     -437-

     

    

 

the
Master Servicer, the Special Servicer, the Trustee, the Operating Advisor, the Certificate Administrator and the Directing Certificateholder
of such disqualification and immediately resign under Section 12.03 of this Agreement and the Trustee shall appoint a successor
asset representations reviewer subject to and in accordance with this Section 12.05. Notwithstanding the foregoing, if
the Trustee is unable to find a successor asset representations reviewer within thirty (30) days of the termination of the Asset
Representations Reviewer, the Depositor shall be permitted to find a replacement. The Trustee shall not be liable for any failure
to identify and appoint a successor asset representations reviewer so long as the Trustee uses commercially reasonable efforts
to conduct a search for a successor asset representations reviewer and such failure is not a result of the Trustee’s negligence,
bad faith or willful misconduct in the performance of its obligations hereunder.

 

(d)          Upon
any termination of the Asset Representations Reviewer and appointment of a successor to the Asset Representations Reviewer, the
Trustee shall, as soon as possible, give written notice thereof to the Special Servicer, the Master Servicer, the Certificate
Administrator (who shall, as soon as possible, give written notice thereof to the Certificateholders), the Operating Advisor,
the Mortgage Loan Sellers, the Depositor, each Rating Agency, and, prior to the occurrence and continuance of a Consultation Termination
Event and the Directing Certificateholder. In the event that the Asset Representations Reviewer is terminated, all of its rights
and obligations under this Agreement shall terminate, other than any rights or obligations that accrued prior to the date of such
termination (including the right to receive all amounts accrued and owing to it under this Agreement) and other than indemnification
rights (arising out of events occurring prior to such termination).

Section
13.07   Grant of a Security Interest. The Depositor intends that the conveyance of the Conveyed Property

applicable law. The Depositor shall file or cause to be filed, as a precautionary filing, a UCC Financing Statement in all
appropriate locations in the State of Delaware promptly following the initial issuance of the Certificates, and the
Certificate Administrator shall, at the expense of the Depositor (to the extent reasonable), 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 statement. 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 of this Agreement) 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.

 

(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 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

 

     -451-

     

    

 

Servicer
and Other Trustee, and any provisions regarding reimbursement or advances or interest thereon to such Other Servicer or Other

of the applicable Non-Serviced Trustee, Non-Serviced Master Servicer, Non-Serviced Special Servicer, Non-Serviced Depositor, Non-Serviced
Paying Agent 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), 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

outstanding principal balances of the Mortgage Loans and (2) $35,000,000;

 

(vi)          any

Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer, as applicable, shall furnish to the 17g-5
Information Provider for posting on the 17g-5 Information Provider’s Website pursuant to Section 3.13(c), and thereafter
to each Rating Agency (and any rating agency for any class of Serviced Companion Loan Securities to the extent applicable to any
Serviced Whole Loan) with respect to each Mortgage Loan (other than any Non-Serviced Mortgage Loan) such information as any Rating
Agency shall reasonably request and which the Trustee, the Certificate Administrator, the Master Servicer or Special Servicer,
can reasonably provide in accordance with applicable law and without waiving any attorney-client privilege relating to such information
or violating the terms of this Agreement or any Mortgage Loan documents. The Trustee, the Certificate Administrator, the Master
Servicer and the Special Servicer, as applicable, may include any reasonable disclaimer it deems appropriate with respect to such
information. Notwithstanding anything to the contrary herein, nothing in this Section 13.10 shall require a party to provide
duplicative notices or copies to the Rating Agencies with respect to any of the above listed items. In connection with the delivery
by the Master Servicer or the Special Servicer to the 17g-5 Information Provider of any information, report, notice or document
for posting to the 17g-5 Information Provider’s Website, the 17g-5 Information Provider shall notify the Master Servicer
or the Special Servicer when such information, report, notice or document has been posted. The Master Servicer or the Special
Servicer, as the case may be, may, but shall not be obligated to, send such information, report, notice or document to the applicable
Rating Agency so long as such information, report, notice or document (i) was previously provided to the 17g-5 Information Provider
or (ii) is simultaneously provided, by 2:00 p.m. (New York City time) on any Business Day, to the 17g-5 Information Provider.

to such Distribution Date at the Pass-Through Rate specified above on the Certificate Balance of this Certificate immediately prior
to each Distribution Date. [FOR CLASS X CERTIFICATES: Interest][FOR PRINCIPAL BALANCE CERTIFICATES (CLASS A-1, A-2, A-SB, A-3,
A-4, A-S, B, C, D, E, F and G): Principal and interest] allocated to this Certificate on any Distribution Date will be in an amount

and Servicing Agreement and the Master Servicer (with respect to the Collection Account) or the Certificate Administrator (with
respect to the Distribution Accounts) will be authorized to make withdrawals therefrom. Amounts on deposit in such accounts may
be invested in Permitted Investments. Interest or other investment income earned on funds in the Collection Account will be paid

the Certificate Register or, provided that such Certificateholder has provided the Certificate Administrator with wire instructions
at least five (5) Business Days prior to the related Record Date, by wire transfer of immediately available funds to the account

this Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders
of such final distribution.

 

Any funds not distributed to any Holder
or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender
their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the
appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate. The costs and expenses of holding such funds in trust and of contacting such Certificateholders
following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out
of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and
Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s)
for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

and Servicing Agreement, the Class [__] Certificates will be issued in book-entry form through the facilities of DTC in minimum

of $1 in excess thereof, with one Certificate of each such Class evidencing an additional amount equal to the remainder of the
initial Certificate Balance of such Class.

 

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

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

with any other provisions therein or to correct any error;

 

(iii)         to
change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided
that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b)
such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance
of doubt, any Holder of an RR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting
such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

 

    A-1-10

     

    

 

(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 an
RR Interest) or Companion Holder;

 

(v)          to
modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of
the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined
that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders
(other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization
or a Disqualified Non-U.S. Tax Person;

 

(vi)         to
revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any
other change; provided that the required action shall not adversely affect in any material respect the interests of any
Certificateholder (including, for the avoidance of doubt, any Holder of an RR Interest) or any holder of a Serviced Pari Passu
Companion Loan not consenting to such revision or addition as evidenced in writing by an Opinion of Counsel, at the expense of
the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect
to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade,
withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

(vii)        to
amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings
assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating
Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement
shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of an RR

 

    A-1-11

     

    

 

Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

 

(viii)       to
modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable
Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as
a Control Termination Event has not occurred and is not continuing and with respect to the Mortgage Loans other than any Excluded
Loan as to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder,
determine that the commercial mortgage-backed securities industry standard for such provisions has changed, in order to conform
to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status
of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c)
each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities,
the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner
as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the
Pooling and Servicing Agreement);

 

(ix)          to
modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided
that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for
the avoidance of doubt, any Holders of the RR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is
then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further,
that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the
17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate
Administrator shall post such notice to the Certificate Administrator’s Website;

 

(x)           to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as will be necessary to comply
with the requirements for use of Form SF-3 in registered offerings to the extent provided in C.F.R. 239.45(b)(1)(ii), (iii) or
(iv); or

 

(xi)          to
modify, eliminate or add to any of its provisions in the event the Risk Retention Rules or any other regulations applicable to
the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with
any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

 

Notwithstanding the foregoing, no such
amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any
Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or

 

    A-1-12

     

    

 

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 evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class
for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing
Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however,
that no such amendment shall:

 

(i)           reduce
in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans that are required to be distributed
on a Certificate of any Class without the consent of the Holder of the Certificate or which are required to be distributed to a
Companion Holder without the consent of such Companion Holder; or

 

(ii)          reduce
the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove
the requirement to obtain consent of any Companion Holder, in any such case without the consent of the Holders of all Certificates
of such Class then-outstanding or such Companion Holders, as applicable; or

 

(iii)         adversely
affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then
outstanding; or

 

(iv)         change
in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations or rights of any Mortgage Loan Seller
under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary
under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

(v)          amend
the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each
Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal
or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating
agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied
with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related
Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

 

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

 

    A-1-13

     

    

 

effect
that such amendment is permitted under the Pooling and Servicing Agreement and that such amendment or the exercise of any power
granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating
Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in
the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a
REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code. Furthermore,
no amendment to the Pooling and Servicing Agreement may be made that changes any provision specifically required to be included
in the Pooling and Servicing Agreement by an Intercreditor Agreement related to a Companion Loan without, in each case, the consent
of the holder of the related Companion Loan(s).

 

The Holder of the majority of the Controlling
Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates, in that order of priority, may, at
their option, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of
any related Mortgage Loan) and the Trust’s portion of each REO Property remaining in the Trust Fund as contemplated by clause
(ii) of the first paragraph of Section 9.01 in the Pooling and Servicing Agreement by giving written notice to the Trustee, the
Certificate Administrator and the other parties to the Pooling and Servicing Agreement no later than sixty (60) days prior to the
anticipated date of purchase; provided, however, that the Holders of the Controlling Class, the Special Servicer,
the Master Servicer, or the Holders of the Class R Certificates may so elect to purchase all of the Mortgage Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund only on or after the first Distribution Date on which the aggregate Stated
Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate
Cut-off Date Balance of the Mortgage Loans.

 

Following the date on which the Class
A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B, Class C and Class D Certificates are no longer outstanding
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class V Certificates, Class R Certificates and the RR Interest)), the Sole Certificateholder shall have the right,
with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class V Certificates, Class R Certificates
and the RR Interest) together with the payment of the Termination Purchase Amount 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.

collections in respect of the Mortgage Loans due after the Cut-off Date, all REO Properties and revenues received in respect thereof,
the mortgagee’s rights under the insurance policies, any Assignment of Leases, and any guaranties or other collateral as

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

 

This Certificate is one of a duly authorized
issue of Certificates designated as Certificates of the series specified on the face hereof (herein called the “Certificates”)
and representing an interest in the Class of Certificates specified on the face hereof equal to the quotient expressed as a percentage
obtained by dividing the Denomination of this Certificate specified on the face hereof, by the aggregate initial Certificate Balance
of the Class R Certificates. The Certificates are designated as the BANK 2017-BNK4, Commercial Mortgage Pass-Through Certificates,
Series 2017-BNK4 and are issued in the classes as specifically set forth in the Pooling and Servicing Agreement. The Certificates
will evidence in the aggregate 100% of the beneficial ownership of the Trust Fund.

 

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

 

This Class R Certificate represents
a “residual interest” in two “real estate mortgage investment conduits”, as those terms are defined, respectively,
in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended (the “Code”). Each Holder of
this Certificate, by acceptance hereof, agrees to treat, and take no action inconsistent with the

 

    A-2-5

     

    

 

treatment
of, this Certificate in accordance with the preceding sentence for purposes of federal income taxes, state and local income and
franchise taxes and other taxes imposed on or measured by income. The Holder of the largest Percentage Interest in the Class R
Certificates shall be the “tax matters person” pursuant to Treasury Regulations Section 1.860F-4(d) and Treasury Regulations
Section 301.6231(a)(7)-1 and the “partnership representative” within the meaning of Section 6223 of the Code (to the
extent such provision is applicable to the Trust REMICs) for each Trust REMIC, and the Certificate Administrator is hereby irrevocably
designated and shall serve (i) as attorney-in-fact and agent for any such Person that is the “tax matters person”
and (ii) as the “partnership representative” for each Trust REMIC within the meaning of Section 6223 of the Code (to
the extent such provision is applicable to the Trust REMIC).

 

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

 

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

 

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

 

    A-2-6

     

    

 

Any funds not distributed to any Holder
or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender
their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the
appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate. The costs and expenses of holding such funds in trust and of contacting such Certificateholders
following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out
of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and
Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s)
for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

Each Person who has or who acquires
any Ownership Interest in a Class R Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to
have agreed to be bound by the following provisions. The rights of each Person acquiring any Ownership Interest in a Class R Certificate
are expressly subject to the following provisions: (A) no Person holding or acquiring any Ownership Interest in a Class R Certificate

the Certificate Registrar as provided in Section 5.03 of the Pooling and Servicing Agreement) incurred by the Certificate Registrar
in connection with such transfer. The Certificate Registrar may require payment by each transferor of a sum sufficient to cover
any tax, expense or other governmental charge payable in connection with any such transfer or exchange.

 

The Trustee, the Certificate Administrator,

The Pooling and Servicing Agreement
may be amended from time to time by the parties thereto, without the consent of any of the Certificateholders or the Companion
Holders:

 

(i)           to
correct any defect or ambiguity in the Pooling and Servicing Agreement in order to address any manifest error in any provision
of the Pooling and Servicing Agreement;

 

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

 

    A-2-8

     

    

 

supplement any of its provisions which may be defective or inconsistent
with any other provisions therein or to correct any error;

 

(iii)         to
change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided
that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b)
such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance
of doubt, any Holder of an RR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting
such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

 

(iv)         to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain
the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code
at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust 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 an

that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders
(other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization
or a Disqualified Non-U.S. Tax Person;

 

(vi)         to

Companion Loan not consenting to such revision or addition as evidenced in writing by an Opinion of Counsel, at the expense of
the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect
to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade,
withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

    A-2-9

     

    

 

(vii)        to
amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings
assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating
Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement
shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of an RR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

 

(viii)       to
modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable
Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as
a Control Termination Event has not occurred and is not continuing and with respect to the Mortgage Loans other than any Excluded
Loan as to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder,
determine that the commercial mortgage-backed securities industry standard for such provisions has changed, in order to conform
to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status
of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c)
each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities,
the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner
as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the
Pooling and Servicing Agreement);

 

(ix)          to
modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided
that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for
the avoidance of doubt, any Holders of the RR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is
then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further,
that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the
17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate
Administrator shall post such notice to the Certificate Administrator’s Website;

 

(x)           to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as will be necessary to comply
with the requirements for use of

 

    A-2-10

     

    

 

Form SF-3 in registered offerings to the extent provided in C.F.R. 239.45(b)(1)(ii), (iii) or
(iv); or

 

(xi)          to
modify, eliminate or add to any of its provisions in the event the Risk Retention Rules or any other regulations applicable to
the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with
any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

 

Notwithstanding the foregoing, no such
amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any
Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as
a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may
materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing Agreement
may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected
by such amendment evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class
for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing
Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however,
that no such amendment shall:

 

(i)            reduce
in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans that are required to be distributed
on a Certificate of any Class without the consent of the Holder of the Certificate or which are required to be distributed to a
Companion Holder without the consent of such Companion Holder; or

 

(ii)          reduce
the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove
the requirement to obtain consent of any Companion Holder, in any such case without the consent of the Holders of all Certificates
of such Class then-outstanding or such Companion Holders, as applicable; or

 

(iii)         adversely
affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then
outstanding; or

 

(iv)         change
in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations or rights of any Mortgage Loan Seller
under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary
under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

(v)          amend
the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each
Rating Agency and confirmation of the applicable rating agencies that such action will not result in the

 

    A-2-11

     

    

 

downgrade, withdrawal
or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating
agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied
with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related
Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

 

Notwithstanding the foregoing, none
of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master
Servicer nor the Special Servicer shall consent to any amendment to the Pooling and Servicing Agreement without having first received
an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing
Agreement and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the
relevant provisions of the Code. Furthermore, no amendment to the Pooling and Servicing Agreement may be made that changes any
provision specifically required to be included in the Pooling and Servicing Agreement by an Intercreditor Agreement related to
a Companion Loan without, in each case, the consent of the holder of the related Companion Loan(s).

 

The Holder of the majority of the Controlling
Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates, in that order of priority, may, at
their option, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of
any related Mortgage Loan) and the Trust’s portion of each REO Property remaining in the Trust Fund as contemplated by clause
(ii) of the first paragraph of Section 9.01 in the Pooling and Servicing Agreement by giving written notice to the Trustee, the
Certificate Administrator and the other parties to the Pooling and Servicing Agreement no later than sixty (60) days prior to the
anticipated date of purchase; provided, however, that the Holders of the Controlling Class, the Special Servicer,
the Master Servicer, or the Holders of the Class R Certificates may so elect to purchase all of the Mortgage Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund only on or after the first Distribution Date on which the aggregate Stated
Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate
Cut-off Date Balance of the Mortgage Loans.

 

Following the date on which the Class
A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B, Class C and Class D Certificates are no longer outstanding
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class V Certificates, Class R Certificates and the RR Interest)), the Sole Certificateholder shall have the right,
with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class V Certificates, Class R Certificates
and the RR Interest) together with the payment of the Termination Purchase Amount

 

    A-2-12

     

    

 

for all
of the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created by the Pooling
and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments
to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate
Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of
the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will
the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on
the date hereof.

 

Unless the certificate of authentication
hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit
under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate
on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty
as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

 

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

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

 

This Certificate is one of a duly authorized
issue of Certificates designated as Certificates of the series specified on the face hereof (herein called the “Certificates”)
and representing an interest in the Class of Certificates specified on the face hereof equal to the quotient expressed as a percentage
obtained by dividing the Denomination of this Certificate specified on the face hereof, by the aggregate initial Certificate Balance
of the Class V Certificates. The Certificates are designated as the BANK 2017-BNK4, Commercial Mortgage Pass-Through Certificates,
Series 2017-BNK4 and are issued in the classes as specifically set forth in the Pooling and Servicing Agreement. The Certificates
will evidence in the aggregate 100% of the beneficial ownership of the Trust Fund.

 

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

 

This Certificate represents an undivided beneficial interest
in a portion of the Excess Interest Grantor Trust Assets. Each Holder of this Certificate, by acceptance hereof, agrees to treat,
and take no action inconsistent with the treatment of, this Certificate in

 

     A-3-4

     

    

 

accordance with the preceding sentence for purposes
of federal income taxes, state and local income and franchise taxes and other taxes imposed on or measured by income.

 

Pursuant to the terms of the Pooling
and Servicing Agreement the Certificate Administrator shall distribute to the Person in whose name this Certificate is registered
as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented
by this Certificate) of the Excess Interest then distributable, if any, allocable to the Class of Certificates of the same Class
as this Certificate for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. All sums distributable
on this Certificate are payable in the coin or currency of the United States of America as at the time of payment is legal tender
for the payment of public and private debts.

 

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

 

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

 

Any funds not distributed to any Holder
or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender
their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the
appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non-

 

     A-3-5

     

    

 

tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate. The costs and expenses of holding such funds in trust and of contacting such Certificateholders
following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out
of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and
Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s)
for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

The Class V Certificates will be issued
in fully registered, certificated form, in minimum percentage interests of 5% and integral multiples of 1% in excess thereof.

 

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

 

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

 

The Pooling and Servicing Agreement
may be amended from time to time by the parties thereto, without the consent of any of the Certificateholders or the Companion
Holders:

 

     A-3-6

     

    

 

(i)       to
correct any defect or ambiguity in the Pooling and Servicing Agreement in order to address any manifest error in any provision
of the Pooling and Servicing Agreement;

 

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

 

(iii)     to
change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided that
(a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b) such
change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance
of doubt, any Holder of an RR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting
such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

 

(iv)     to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain
the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code
at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust, any Trust
REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel (at
the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain such
qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect
in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of an RR Interest)
or Companion Holder;

 

(v)      to
modify, eliminate or add to the provisions of Section 5.03(n) of the Pooling and Servicing Agreement or any other provision of
the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined
that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders
(other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization
or a Disqualified Non-U.S. Tax Person;

 

(vi)     to
revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any
other change; provided that the required action shall not adversely affect in any material respect the interests of any
Certificateholder (including, for the avoidance of doubt, any Holder of an RR Interest) or
any holder of a Serviced Pari Passu Companion Loan not consenting to such revision or addition as evidenced in writing by an Opinion
of Counsel, at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each

 

     A-3-7

     

    

 

of
the Rating Agencies with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action
will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities,
if any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency
Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing
Agreement);

 

(vii)    to
amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings
assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating
Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement
shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of an RR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

 

(viii)   to
modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable
Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as
a Control Termination Event has not occurred and is not continuing and with respect to the Mortgage Loans other than any Excluded
Loan as to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder,
determine that the commercial mortgage-backed securities industry standard for such provisions has changed, in order to conform
to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status
of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c)
each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities,
the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner
as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the
Pooling and Servicing Agreement);

 

(ix)      to
modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided
that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for
the avoidance of doubt, any Holder of the RR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is
then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further,

 

     A-3-8

     

    

 

that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the
17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate
Administrator shall post such notice to the Certificate Administrator’s Website;

 

(x)       to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as will be necessary to comply
with the requirements for use of Form SF-3 in registered offerings to the extent provided in C.F.R. 239.45(b)(1)(ii), (iii) or
(iv); or

 

(xi)      to
modify, eliminate or add to any of its provisions in the event the Risk Retention Rules or any other regulations applicable to
the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with
any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

 

Notwithstanding the foregoing, no such
amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any
Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as
a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may
materially and adversely affect the holder of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing Agreement
may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected
by such amendment evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class
for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing
Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however,
that no such amendment shall:

 

(i)       reduce
in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans that are required to be distributed
on a Certificate of any Class without the consent of the Holder of the Certificate or which are required to be distributed to a
Companion Holder without the consent of such Companion Holder; or

 

(ii)       reduce
the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove
the requirement to obtain consent of any Companion Holder, in any such case without the consent of the Holders of all Certificates
of such Class then-outstanding or such Companion Holders, as applicable; or

 

(iii)       adversely
affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then
outstanding; or

 

(iv)       change
in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations or rights of any Mortgage Loan Seller
under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage

 

     A-3-9

     

    

 

Loan Seller as a third party beneficiary
under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

(v)       amend
the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each
Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal
or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency
confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with
respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related
Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

 

Notwithstanding the foregoing, none
of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master
Servicer nor the Special Servicer shall consent to any amendment to the Pooling and Servicing Agreement without having first received
an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing
Agreement and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the
relevant provisions of the Code. Furthermore, no amendment to the Pooling and Servicing Agreement may be made that changes any
provision specifically required to be included in the Pooling and Servicing Agreement by an Intercreditor Agreement related to
a Companion Loan without, in each case, the consent of the holder of the related Companion Loan(s).

 

The Holder of the majority of the Controlling
Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates, in that order of priority, may, at
their option, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of
any related Mortgage Loan) and the Trust’s portion of each REO Property remaining in the Trust Fund as contemplated by clause
(ii) of the first paragraph of Section 9.01 in the Pooling and Servicing Agreement by giving written notice to the Trustee, the
Certificate Administrator and the other parties to the Pooling and Servicing Agreement no later than sixty (60) days prior to the
anticipated date of purchase; provided, however, that the Holders of the Controlling Class, the Special Servicer,
the Master Servicer, or the Holders of the Class R Certificates may so elect to purchase all of the Mortgage Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund only on or after the first Distribution Date on which the aggregate Stated
Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate
Cut-off Date Balance of the Mortgage Loans.

 

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

 

     A-3-10

     

    

 

provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class V Certificates, Class R Certificates and the RR Interest)), the Sole Certificateholder shall have the right,
with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class V Certificates, Class R Certificates
and the RR Interest) together with the payment of the Termination Purchase Amount for all of the Mortgage Loans and each REO Property
remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created by the Pooling
and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator to make payments
to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction of the Certificate
Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from a termination of
the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event, however, will
the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on
the date hereof.

 

Unless the certificate of authentication
hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled to any benefit
under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this Certificate
on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation or warranty
as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

 

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

THIS CERTIFIES THAT [FOR BOOK-ENTRY CERTIFICATES AND
SOLELY FOLLOWING THE RR INTEREST TRANSFER RESTRICTION PERIOD: CEDE & CO.] [FOR DEFINITIVE CERTIFICATES: [WELLS FARGO BANK,
NATIONAL ASSOCIATION][BANK OF AMERICA, NATIONAL ASSOCIATION][MORGAN STANLEY BANK, N.A.]] is the registered owner of the interest
evidenced by this Certificate in the RR Interest issued by the Trust created pursuant to the Pooling and Servicing Agreement, dated
as of April 1, 2017 (the “Pooling and Servicing Agreement”), between WELLS FARGO COMMERCIAL MORTGAGE SECURITIES,
INC. (hereinafter called the “Depositor”, which term includes any successor entity under the Pooling and Servicing
Agreement), the Trustee, the Master Servicer, the Special Servicer, the Certificate Administrator, the Operating Advisor and the
Asset Representations Reviewer. A summary of certain of the pertinent provisions of the Pooling and Servicing Agreement is set
forth hereafter. To the extent not defined herein, the capitalized terms used herein shall have the meanings assigned thereto in
the Pooling and Servicing Agreement.

 

This Certificate is one of a duly authorized
issue of Certificates designated as Certificates of the series specified on the face hereof (herein called the “Certificates”)
and representing an interest in the Class of Certificates specified on the face hereof equal to the quotient expressed as a percentage
obtained by dividing the Denomination of this Certificate specified on the face hereof, by the aggregate initial Certificate Balance
of the RR Interest. The Certificates are designated as the BANK 2017-BNK4, Commercial Mortgage Pass-Through Certificates, Series
2017-BNK4 and are issued in the classes as specifically set forth in the Pooling and Servicing Agreement. The Certificates will
evidence in the aggregate 100% of the beneficial ownership of the Trust Fund.

 

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

 

     A-4-5

     

    

 

This Certificate represents (i) a “regular
interest” in a “real estate mortgage investment conduit”, as those terms are defined, respectively, in Sections
860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended (the “Code”) and (ii) an undivided beneficial
interest in a portion of the Excess Interest Grantor Trust Assets. Each Holder of this Certificate, by acceptance hereof, agrees
to treat, and take no action inconsistent with the treatment of, this Certificate in accordance with the preceding sentence for
purposes of federal income taxes, state and local income and franchise taxes and other taxes imposed on or measured by income

 

Pursuant to the terms of the Pooling
and Servicing Agreement, the Certificate Administrator shall distribute to the Person in whose name this Certificate is registered
as of the related Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented
by this Certificate) of that portion of the aggregate amount of principal and interest (including Excess Interest) then distributable,
if any, allocable to the Class of Certificates of the same Class as this Certificate for such Distribution Date, all as more fully
described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to Prepayment Premiums and Yield
Maintenance Charges as provided in the Pooling and Servicing Agreement. All sums distributable on this Certificate are payable
in the coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and
private debts.

 

Interest on this Certificate will accrue
(computed as if each year consisted of 360 days and each month consisted of 30 days) during the Interest Accrual Period relating
to such Distribution Date at the Pass-Through Rate on the Certificate Balance of this Certificate immediately prior to each Distribution
Date. Principal and interest allocated to this Certificate on any Distribution Date will be in an amount equal to this Certificate’s
pro rata share of the Aggregate Available Funds to be distributed on the Certificates of this Class as of such Distribution
Date, with a final distribution to be made upon retirement of this Certificate as set forth in the Pooling and Servicing Agreement.

 

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

 

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

 

     A-4-6

     

    

 

expenses
incurred with respect to the servicing of the Mortgage Loans and administration of the Trust.

 

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

 

Any funds not distributed to any Holder
or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders to tender
their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts of the
appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate. The costs and expenses of holding such funds in trust and of contacting such Certificateholders
following the first anniversary of the delivery of such second notice to the non-tendering Certificateholders shall be paid out
of such funds. No interest shall accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and
Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s)
for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

As provided in the Pooling and Servicing
Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate
Register only upon receipt by the Certificate Administrator of (i) a certificate from the prospective Transferee in the form set
forth in the Pooling and Servicing Agreement, countersigned by the Risk Retention Consultation Party and (ii) a certificate from
the prospective Transferor in the form set forth in the Pooling and Servicing Agreement.

 

The RR Interest will be issued in fully
registered, certificated form in minimum denominations of $1, and in integral multiples of $0.01 in excess thereof, with one Certificate
of each such Class evidencing an additional amount equal to the remainder of the initial Certificate Balance of such Class.

 

     A-4-7

     

    

 

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

 

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

 

The Pooling and Servicing Agreement
may be amended from time to time by the parties thereto, without the consent of any of the Certificateholders or the Companion
Holders:

 

(i)       to
correct any defect or ambiguity in the Pooling and Servicing Agreement in order to address any manifest error in any provision
of the Pooling and Servicing Agreement;

 

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

 

(iii)       to
change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts or any REO Account; provided
that (a) the P&I Advance Date shall in no event be later than the Business Day prior to the related Distribution Date and (b)
such change shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance
of doubt, any Holder of an RR Interest), as evidenced in writing by an Opinion of Counsel at the expense of the party requesting
such amendment or as evidenced by a Rating Agency Confirmation from each Rating Agency with respect to such amendment;

 

(iv)       to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain
the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code
at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust 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

 

     A-4-8

     

    

 

minimize the risk of the imposition of any such tax and (b) such action will not adversely
affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of an
RR Interest) or Companion Holder;

 

(v)       to
modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of
the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined
that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders
(other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization
or a Disqualified Non-U.S. Tax Person;

 

(vi)       to
revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any
other change; provided that the required action shall not adversely affect in any material respect the interests of any
Certificateholder (including, for the avoidance of doubt, any Holder of an RR Interest) or any holder of a Serviced Pari Passu
Companion Loan not consenting to such revision or addition as evidenced in writing by an Opinion of Counsel, at the expense of
the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect
to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade,
withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

(vii)       to
amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current ratings
assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating
Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation
may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the
Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement
shall not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of an RR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

 

(viii)       to
modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable
Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as
a Control Termination Event has not occurred and is not continuing and with respect to the Mortgage Loans other than any Excluded
Loan as to the Directing Certificateholder or the Holder of the majority of the Controlling Class, the Directing Certificateholder,
determine that the commercial mortgage-backed securities

 

     A-4-9

     

    

 

industry standard for such provisions has changed, in order to conform
to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status
of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c)
each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities,
the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same manner
as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the
Pooling and Servicing Agreement);

 

(ix)       to
modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided
that such amendment shall not adversely affect in any material respects the interests of any Certificateholders (including, for
the avoidance of doubt, any Holders of the RR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is
then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided, further,
that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the
17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate
Administrator shall post such notice to the Certificate Administrator’s Website;

 

(x)       to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as will be necessary to comply
with the requirements for use of Form SF-3 in registered offerings to the extent provided in C.F.R. 239.45(b)(1)(ii), (iii) or
(iv); or

 

(xi)       to
modify, eliminate or add to any of its provisions in the event the Risk Retention Rules or any other regulations applicable to
the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply with
any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such repeal.

 

Notwithstanding the foregoing, no such
amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations of any
Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as
a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller or (B) may
materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing Agreement
may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each Class affected
by such amendment evidencing in the aggregate not less than a majority of the aggregate Percentage Interests constituting the Class
for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing
Agreement or of

 

     A-4-10

     

    

 

modifying in any manner the rights of the Holders of Certificates of such Class; provided, however,
that no such amendment shall:

 

(i)       reduce
in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans that are required to be distributed
on a Certificate of any Class without the consent of the Holder of the Certificate or which are required to be distributed to a
Companion Holder without the consent of such Companion Holder; or

 

(ii)       reduce
the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or remove
the requirement to obtain consent of any Companion Holder, in any such case without the consent of the Holders of all Certificates
of such Class then-outstanding or such Companion Holders, as applicable; or

 

(iii)       adversely
affect the Voting Rights of any Class of Certificates without the consent of the Holders of all Certificates of such Class then
outstanding; or

 

(iv)       change
in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations or rights of any Mortgage Loan Seller
under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary
under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

(v)       amend
the Servicing Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each
Rating Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal
or qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating
agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied
with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related
Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

 

Notwithstanding the foregoing, none
of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor, the Master
Servicer nor the Special Servicer shall consent to any amendment to the Pooling and Servicing Agreement without having first received
an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted under the Pooling and Servicing
Agreement and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor,
the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the
relevant provisions of the Code. Furthermore, no amendment to the Pooling and Servicing Agreement may be made that changes any
provision specifically required to be included in the Pooling and Servicing Agreement by an Intercreditor

 

     A-4-11

     

    

 

Agreement related to
a Companion Loan without, in each case, the consent of the holder of the related Companion Loan(s).

 

The Holder of the majority of the Controlling
Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates, in that order of priority, may, at
their option, elect to purchase all of the Mortgage Loans (and all property acquired through exercise of remedies in respect of
any related Mortgage Loan) and the Trust’s portion of each REO Property remaining in the Trust Fund as contemplated by clause
(ii) of the first paragraph of Section 9.01 in the Pooling and Servicing Agreement by giving written notice to the Trustee, the
Certificate Administrator and the other parties to the Pooling and Servicing Agreement no later than sixty (60) days prior to the
anticipated date of purchase; provided, however, that the Holders of the Controlling Class, the Special Servicer,
the Master Servicer, or the Holders of the Class R Certificates may so elect to purchase all of the Mortgage Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund only on or after the first Distribution Date on which the aggregate Stated
Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate
Cut-off Date Balance of the Mortgage Loans.

 

Following the date on which the Class
A-1, Class A-2, Class A-SB, Class A-3, Class A-4, Class A-S, Class B, Class C and Class D Certificates are no longer outstanding
(and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class V Certificates, Class R Certificates and the RR Interest), the Sole Certificateholder shall have the right,
with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class V Certificates, Class R Certificates
and the RR Interest) together with the payment of the Termination Purchase Amount 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.

pursuant to Section 5.03 of the Pooling and Servicing Agreement, dated as of April 1, 2017 (the “Pooling and Servicing
Agreement”), by and among Wells Fargo Commercial Mortgage Securities, Inc., as Depositor, Wells Fargo Bank, National

Series 2017-BNK4 in connection with the transfer by _________________ (the “Seller”) to the undersigned (the
“Purchaser”) of $_______________ aggregate [Certificate Balance][Notional Amount][__% Percentage Interest] of
Class ___ Certificates (the “Certificates”). Capitalized terms used and not otherwise defined herein shall have
the respective meanings ascribed to such terms in the Pooling and Servicing Agreement.

 

    Exhibit C-1

     

    

 

In connection with such
transfer, the Purchaser hereby represents and warrants to you and the addressees hereof as follows:

 

1.       Check
one of the following:*

 

		☐	The Purchaser is not purchasing a Class R Certificate and the Purchaser is an institution that
is an “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D (“Regulation
D”) under the Securities Act of 1933, as amended (the “Securities Act”) or any entity in which all
of the equity owners are “accredited investors” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation
D (each, an “Institutional Accredited Investor”) and has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of its investment in the Certificates, and the Purchaser and any accounts
for which it is acting are each able to bear the economic risk of the Purchaser’s or such account’s investment. The
Purchaser is acquiring the Certificates purchased by it for its own account or for one or more accounts, each of which is an Institutional
Accredited Investor, as to each of which the Purchaser exercises sole investment discretion. The Purchaser hereby undertakes to
reimburse the Trust for any costs incurred by it in connection with this transfer.

 

		☐	The Purchaser is a “qualified institutional buyer” (a “QIB”) within
the meaning of Rule 144A (“Rule 144A”) under the Securities Act. The Purchaser is aware that the transfer is
being made in reliance on Rule 144A, and the Purchaser has had the opportunity to obtain the information required to be provided
pursuant to paragraph (d)(4)(i) of Rule 144A.

 

2.       The
Purchaser’s intention is to acquire the Certificates (a) for investment for the Purchaser’s own account or (b) for
reoffer, resale, pledge or other transfer (i) to QIBs in transactions under Rule 144A, and not in any event with the view to, or
for resale in connection with, any distribution thereof, or (ii) (other than with respect to a Class R Certificate) to Institutional
Accredited Investors, subject in the case of clause (ii) above to (w) the receipt by the Certificate Registrar of a letter substantially
in the form hereof, (x) the receipt by the Certificate Registrar of an opinion of counsel acceptable to the Trustee and Certificate
Registrar that such reoffer, resale, pledge or transfer is in compliance with the Securities Act, (y) the receipt by the Certificate
Registrar of such other evidence acceptable to the Certificate Registrar that such reoffer, resale, pledge or transfer is in compliance
with the Securities Act and other applicable laws and (z) a written undertaking to reimburse the Trust for any costs incurred by
it in connection with the proposed transfer. The Purchaser understands that the Certificates (and any subsequent Certificates)
have not been registered under the Securities Act, by reason of a specified exemption from the registration provisions of the Securities
Act which depends upon, among other things, the bona fide nature of the Purchaser’s investment intent (or intent to reoffer,
resell, pledge or transfer the Certificates only to certain investors in certain exempted transactions) as expressed herein.

 

 

 

* Purchaser must select one
of the following two certifications.

 

    Exhibit C-2

     

    

 

3.       The

related to such Offered Private Certificates) and the agreements and other materials referred to therein and has had the opportunity
to ask questions and receive answers concerning the terms and conditions of the transactions contemplated by the Prospectus.

 

4.       The
Purchaser acknowledges that the Certificates (and any Certificates issued on transfer or exchange thereof) have not been registered
or qualified under the Securities Act or the securities laws of any State or any other jurisdiction, and that the Certificates
cannot be reoffered, resold, pledged or otherwise transferred unless it is registered or qualified thereunder or unless an exemption
from such registration or qualification is available.

 

5.       The
Purchaser hereby undertakes to be bound by the terms and conditions of the Pooling and Servicing Agreement in its capacity as an
owner of a Certificate or Certificates, as the case may be (each, a “Certificateholder”), in all respects as
if it were a signatory thereto. This undertaking is made for the benefit of the Trust, the Certificate Registrar and all Certificateholders
present and future.

 

6.       The

5.03 of the Pooling and Servicing Agreement.

		Re:	BANK 2017-BNK4, Commercial Mortgage Pass-Through Certificates, Series 2017-BNK4
(the “Certificates”) issued
pursuant to the Pooling and Servicing Agreement (the “Pooling

Inc., as Depositor, Wells Fargo Bank, National Association, as Master Servicer, Rialto Capital Advisors, LLC, as Special Servicer,
Wells Fargo Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, and Pentalpha
Surveillance LLC, as Operating Advisor and as Asset Representations Reviewer

 

	STATE OF	)	 
	 	)	ss.:
	COUNTY OF	)	 

  

I, [______], under penalties
of perjury, declare that, to the best of my knowledge and belief, the following representations are true, correct and complete,
and being first sworn, depose and say that:

 

1.        I
am a [______] of [______] (the “Purchaser”),
on behalf of which I have the authority to make this affidavit.

 

2.        The
Purchaser is acquiring Class R Certificates representing [__]% of the residual interest in each of the real estate mortgage investment
conduits (each, a “REMIC”)
designated as the (i) “Lower-Tier REMIC”
and (ii) “Upper-Tier REMIC”,
respectively, relating to the Certificates for which an election is to be made under Section 860D of the Internal Revenue Code
of 1986 (the “Code”).

 

3.        The
Purchaser is not a “Disqualified Organization”
(as defined below), and that the Purchaser is not acquiring the Class R Certificates for the account of, or as agent or nominee
of, or with a view to the transfer of direct or indirect record or beneficial ownership thereof, to a Disqualified Organization.
For the purposes hereof, a Disqualified Organization is

 

    Exhibit D-1-1

     

    

 

any of the following: (i) the United States, any State or political subdivision
thereof, any possession of the United States or any agency or instrumentality of any of the foregoing (other than an instrumentality
which is a corporation if all of its activities are subject to tax and, except for the Federal Home Loan Mortgage Corporation,
a majority of its board of directors is not selected by such governmental unit), (ii) a foreign government, any international organization
or any agency or instrumentality of any of the foregoing, (iii) any organization which is exempt from the tax imposed by Chapter
1 of the Code (including the tax imposed by Section 511 of the Code on unrelated business taxable income) on any excess inclusions
(as defined in Section 860E(c)(1) of the Code) with respect to the Class R Certificates (except certain farmers’ cooperatives
described in Section 521 of the Code), (iv) rural electric and telephone cooperatives described in Section 1381(a)(2)(C) of the
Code, (v) an “electing large partnership”, as defined in Section 775 of the Code and (vi) any other Person so designated
by the Trustee or the Certificate Administrator based upon an Opinion of Counsel as provided to the Trustee or the Certificate
Administrator (at no expense to the Trustee or the Certificate Administrator) that the holding of an Ownership Interest in a Class
R Certificate by such Person may cause a Trust REMIC to fail to qualify as a REMIC at any time that the Certificates are outstanding
or any Person having an Ownership Interest in any Class of Certificates (other than such Person) to incur a liability for any federal
tax imposed under the Code that would not otherwise be imposed but for the Transfer of an Ownership Interest in a Class R Certificate
to such Person. The terms “United States,” “State” and “international organization” shall have
the meanings set forth in Section 7701 of the Code or successor provisions.

 

4.        The
Purchaser acknowledges that Section 860E(e) of the Code would impose a substantial tax on the transferor or, in certain circumstances,
on an agent for the transferee, with respect to any transfer of any interest in any Class R Certificates to a Disqualified Organization.

 

5.        The
Purchaser is a Permitted Transferee and, to the extent applicable, the Purchaser’s U.S. taxpayer identification number is
[__________].

 

6.        No
purpose of the acquisition of the Class R Certificates is to impede the assessment or collection of tax.

 

7.        The
Purchaser will not cause income from the Class R Certificate to be attributable to a foreign permanent establishment or fixed base,
within the meaning of an applicable income tax treaty, of the Purchaser or any other person.

 

8.        Check
the applicable paragraph:

 

☐        The present
value of the anticipated tax liabilities associated with holding the Class R Certificate, as applicable, does not exceed the sum
of:

 

(i)       the
present value of any consideration given to the Purchaser to acquire such Class R Certificate;

 

(ii)      the
present value of the expected future distributions on such Class R Certificate; and

 

    Exhibit D-1-2

     

    

 

(iii)     the
present value of the anticipated tax savings associated with holding such Class R Certificate as the related REMIC generates losses.

 

For purposes of this
calculation, (i) the Purchaser is assumed to pay tax at the highest rate currently specified in Section 11(b) of the Code (but
the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in Section 11(b) of the Code
if the Purchaser has been subject to the alternative minimum tax under Section 55 of the Code in the preceding two years and will
compute its taxable income in the current taxable year using the alternative minimum tax rate) and (ii) present values are computed
using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d) of the Code for the month of the transfer
and the compounding period used by the Purchaser.

 

☐       The
transfer of the Class R Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

 

(i)       the
Purchaser is an “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to which
income from the Class R Certificate will only be taxed in the United States;

 

(ii)      at
the time of the transfer, and at the close of the Purchaser’s two fiscal years preceding the year of the transfer, the Purchaser
had gross assets for financial reporting purposes (excluding any obligation of a person related to the Purchaser within the meaning
of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;

 

(iii)     the
Purchaser will transfer the Class R Certificate only to another “eligible corporation,” as defined in Treasury Regulations
Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of Sections 1.860E-1(c)(4)(i), (ii) and (iii) and Treasury
Regulations Section 1.860E-1(c)(5); and

 

(iv)     the
Purchaser determined the consideration paid to it to acquire the Class R Certificate based on reasonable market assumptions (including,
but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax
rates and other factors specific to the Purchaser) that it has determined in good faith.

 

☐       None
of the above.

 

9.        The
Purchaser historically has paid its debts as they have come due and intends to pay its debts as they come due in the future and
the Purchaser intends to pay taxes associated with holding the Class R Certificates as they become due.

 

10.      The
Purchaser understands that it may incur tax liabilities with respect to the Class R Certificate in excess of any cash flows generated
by such Certificate.

 

11.      The
Purchaser is aware that the Certificate Registrar will not register any transfer of a Class R Certificate by the Transferor unless
the Purchaser, or such Purchaser’s agent, delivers to the Certificate Registrar, among other things, an affidavit and agreement
in substantially the same form as this affidavit and agreement. The Purchaser expressly agrees that

 

    Exhibit D-1-3

     

    

 

it will not consummate any
such transfer if it knows or believes that any representation contained in such affidavit and agreement is false.

 

12.      The
Purchaser represents that it is not acquiring the Class R Certificate as a nominee, trustee or agent for any person that is not
a Permitted Transferee and that for so long as it retains its interest in the Class R Certificate, it will endeavor to remain a
Permitted Transferee.

 

13.      The
Purchaser consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificate will only be owned, directly or indirectly, by a Permitted Transferee.

 

14.      The
Purchaser has reviewed the provisions of Section 5.03 of the Pooling and Servicing Agreement, a description of which provisions
is set forth in the Class R Certificates; and the Purchaser expressly agrees to be bound by and to comply with such provisions.

 

15.      The
Purchaser consents to the designation of the Certificate Administrator as the agent of the “tax matters person” and
“partnership representative” of each Trust REMIC pursuant to Section 10.01 of the Pooling and Servicing Agreement.

 

Capitalized terms used
but not defined herein have the meanings assigned thereto in the Pooling and Servicing Agreement.

(the “Certificates”) 

 

Ladies and Gentlemen:

 

This letter is delivered
to you in connection with the transfer by [______] (the “Transferor”)
to [______] (the “Transferee”)
of Class R Certificates evidencing a [__]% Percentage Interest in such Class (the “Residual
Certificates”). The Certificates, including the Residual Certificates, were issued pursuant to the Pooling and
Servicing Agreement, dated as of April 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Wells Fargo Commercial Mortgage Securities, Inc., as Depositor, Wells
Fargo Bank, National Association, as Master Servicer, Rialto Capital Advisors, LLC, as Special Servicer, Wells Fargo Bank, National
Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, and Pentalpha Surveillance LLC,
as Operating Advisor and as Asset Representations Reviewer. All capitalized terms used but not otherwise defined herein shall have
the respective meanings set forth in the Pooling and Servicing Agreement. The Transferor hereby certifies, represents and warrants
to you, as Certificate Registrar, that:

 

(1)       No
purpose of the Transferor relating to the transfer of the Residual Certificates by the Transferor to the Transferee is or will
be to impede the assessment or collection of any tax.

 

(2)       The
Transferor understands that the Transferee has delivered to you a Transferee Affidavit and Agreement in the form attached to the
Pooling and Servicing Agreement as Exhibit D-1. The Transferor does not know or believe that any representation contained
therein is false.

 

(3)       The
Transferor has at the time of this transfer conducted a reasonable investigation of the financial condition of the Transferee as
contemplated by Treasury regulation Section 1.860E-1(c)(4)(i) and, as a result of that investigation, the Transferor has determined
that the Transferee has historically paid its debts as they became due and has found no significant

 

    Exhibit D-2-1

     

    

 

evidence to indicate that the
Transferee will not continue to pay its debts as they become due in the future. The Transferor understands that the transfer of
the Residual Certificates may not be respected for United States income tax purposes (and the Transferor may continue to be liable
for United States income taxes associated therewith) unless the Transferor has conducted such an investigation.

(1) Debt Service Coverage Ratios are updated periodically as new NOI figures become available from borrowers on an asset level. In all cases, the most recent DSCR provided by the Servicer is used. To the extent that no DSCR is provided by the Servicer, information from the offering document is used. The Trustee makes no representations as to the accuracy of the data provided by the borrower for this calculation.

	 
	 	 	 
	 	(2) Anticipated Remaining Term and WAM are each calculated based upon the term from the current month to the earlier of the Anticipated Repayment Date, if applicable, and the maturity date.	 
	 	 	 
	 	(3) Data in this table was calculated by allocating pro-rata the current loan information to the properties based upon the Cut-off Date balance of each property as disclosed in the offering document.

Definition of Confidential Information.
For purposes of this Confidentiality Agreement, the term “Confidential Information” shall include the following

site) that may be furnished to you by or on behalf of a Furnishing Entity in connection with the issuance or monitoring of a rating
with respect to the Certificates: (x) all data, reports, interpretations, forecasts, records, agreements, legal documents and other
information (such information, the “Evaluation Material”) and (y) any of the terms, conditions or other facts
with respect to the transactions contemplated by the Pooling and Servicing Agreement, including the status thereof; provided,
however, that the term Confidential Information shall not include information which:

 

was or becomes generally
available to the public (including through filing with the Securities and Exchange Commission or disclosure in an offering document)
other than as a result of a disclosure by you or a NRSRO Representative (as defined in Section 2(c)(i) below) in violation
of this Confidentiality Agreement;

 

was or is lawfully
obtained by you from a source other than a Furnishing Entity or its representatives that (i) is reasonably believed by you to be
under no obligation to maintain the information as confidential and (ii) provides it to you without any obligation to maintain
the information as confidential; or

 

is independently developed
by the NRSRO without reference to any Confidential Information.

 

Information to Be Held in Confidence.

 

You will use the Confidential
Information solely for the purpose of determining or monitoring a credit rating on the Certificates and, to the extent that any
information used is derived from but does not reveal any Confidential Information, for benchmarking, modeling or research purposes
(the “Intended Purpose”).

 

You acknowledge that
you are aware that the United States and state securities laws impose restrictions on trading in securities when in possession
of material, non-public information and that the NRSRO will advise (through policy manuals or otherwise) each NRSRO Representative
who is informed of the matters that are the subject of this Confidentiality Agreement to that effect.

 

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

 

    	Exhibit P-2-3 

     

    

 

disclose
the Confidential Information to any of the NRSRO’s affiliates, directors, officers, employees, legal representatives, agents
and advisors (each, a “NRSRO Representative”) who, in the reasonable judgment of the NRSRO, need to know such
Confidential Information in connection with the Intended Purpose; provided, that, prior to disclosure of the Confidential
Information to a NRSRO Representative, the NRSRO shall have taken reasonable precautions to ensure, and shall be satisfied, that
such NRSRO Representative will act in accordance with this Confidentiality Agreement;

 

solely to
the extent required for compliance with Rule 17g-5(a)(3) of the Act (17 C.F.R. 240.17g-5),post the Confidential Information to
the NRSRO’s password protected website; and

 

use information
derived from the Confidential Information in connection with an Intended Purpose, if such derived information does not reveal any
Confidential Information.

 

Disclosures Required by Law. If
you or any NRSRO Representative is requested or required (orally or in writing, by interrogatory, subpoena, civil investigatory
demand, request for information or documents, deposition or similar process relating to any legal proceeding, investigation, hearing
or otherwise) to disclose any Confidential Information, you agree to provide the relevant Furnishing Entity with notice as soon
as practicable (except in the case of regulatory or other governmental inquiry, examination or investigation, and otherwise to
the extent practical and permitted by law, regulation or regulatory or other governmental authority) that a request to disclose
the Confidential Information has been made so that the relevant Furnishing Entity may seek an appropriate protective order or other
reasonable assurance that confidential treatment will be accorded the Confidential Information if it so chooses. Unless otherwise
required by a court or other governmental or regulatory authority to do so, and provided that you been informed by written notice
that the related Furnishing Entity is seeking a protective order or other reasonable assurance for confidential treatment with
respect to the requested Confidential Information, you agree not to disclose the Confidential Information while the Furnishing
Entity’s effort to obtain such a protective order or other reasonable assurance for confidential treatment is pending. You
agree to reasonably cooperate with each Furnishing Entity in its efforts to obtain a protective order or other reasonable assurance
that confidential treatment will be accorded to the portion of the Confidential Information that is being disclosed, at the sole
expense of such Furnishing Entity; provided, however, that in no event shall the NRSRO be required to take a position
that such information should be entitled to receive such a protective order or reasonable assurance as to confidential treatment.
If a Furnishing Entity succeeds in obtaining a protective order or other remedy, you agree to comply with its terms with respect
to the disclosure of the Confidential Information, at the sole expense of such Furnishing Entity. If a protective order or other
remedy is not obtained or if the relevant Furnishing Entity waives compliance with the provisions of this Confidentiality Agreement
in writing, you agree to furnish only such information as you are legally required to disclose, at the sole expense of the relevant
Furnishing Entity.

 

Obligation to Return Evaluation Material.
Promptly upon written request by or on behalf of the relevant Furnishing Entity, all material or documents, including copies thereof,
that contain Evaluation Material will be destroyed or, in your sole discretion, returned to the relevant Furnishing Entity. Notwithstanding
the foregoing, (a) the NRSRO may retain one or more copies of any document or other material containing Evaluation Material to
the extent necessary for legal or regulatory compliance (or compliance with the NRSRO’s internal policies and procedures
designed to ensure legal or regulatory compliance) and (b) the NRSRO may retain any portion of the Evaluation Material that may
be found in backup tapes or other archive or electronic media or other documents prepared by the NRSRO and any Evaluation Material
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. Notwithstanding the termination
or cancellation of this Confidentiality Agreement and regardless of whether the NRSRO has provided a credit rating on a Security,
your obligations under this Confidentiality Agreement will survive indefinitely.

 

Governing Law. This Confidentiality
Agreement and any claim, controversy or dispute arising under the Confidentiality Agreement, the relationships of the parties and/or
the interpretation and enforcement of the rights and duties of the parties shall be governed by and construed in accordance with
the laws of the State of New York applicable to agreements made and to be performed within such State.

 

Amendments. This Confidentiality
Agreement may be modified or waived only by a separate writing by the NRSRO and each Furnishing Entity.

 

Entire Agreement. This Confidentiality
Agreement represents the entire agreement between you and the Furnishing Entities relating to the treatment of Confidential Information
heretofore or hereafter reviewed or inspected by you. This agreement supersedes all other understandings and agreements between
us relating to such matters; provided, however, that, if the terms of this Confidentiality Agreement conflict with
another agreement relating to the Confidential Information that specifically states that the terms of such agreement shall supersede,
modify or amend the terms of this Confidentiality Agreement, then to the extent the terms of this Confidentiality Agreement conflict
with such agreement, the terms of such agreement shall control notwithstanding acceptance by you of the terms hereof by entry into
this website.

or powers herein is not intended to, nor does it give rise to, and it is not to be construed as a general power of attorney.

 

Solely

Power of Attorney, for purposes of performing its obligations and duties by executing such additional powers of attorney in favor

The
Special Servicer hereby agrees to indemnify and hold the Trustee and its directors, officers, employees and agents harmless from
and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever incurred by reason or result of the negligent use, or negligent or willful misuse, of this Limited
Power of Attorney by the Special Servicer. The foregoing indemnity shall survive the termination of this Limited Power of Attorney
and the Agreement or the earlier resignation or removal of the Trustee under the Agreement.

 

This
Limited Power of Attorney is entered into and shall be governed by the laws of the State of New York, without regard to conflicts
of law principles of such state.

 

Third
parties without actual notice may rely upon the exercise of the power granted under this Limited Power of Attorney; and may be
satisfied that this Limited Power of Attorney shall continue in full force and effect and has not been revoked unless an instrument
of revocation has been made in writing by the undersigned.

Ladies
and Gentlemen:

 

As
you know, [_____], acts as the master servicer (the “Lead Servicer”) for the whole loan secured by the mortgaged
property identified as [NON-SERVICED WHOLE LOAN] (the “Subject Whole Loan”) under the pooling and servicing
agreement relating to the [_____] securitization trust (the “PSA”). This is to inform you that one or more
of the promissory notes related to the Subject Whole Loan (the “Subject Mortgage Loan”) has been transferred
to BANK 2017-BNK4 pursuant to that certain Pooling and Servicing Agreement, dated April 1, 2017 (the “2017-BNK4 Pooling
and Servicing Agreement”) by and among Wells Fargo Commercial Mortgage Securities, Inc., as depositor, Wells Fargo Bank,
National Association, as master servicer (in such capacity, the “2017-BNK4 Master Servicer”), Rialto Capital
Advisors, LLC, as special servicer, Wells Fargo Bank, National Association, as certificate administrator (in such capacity, the
“2017-BNK4 Certificate Administrator”), Wilmington Trust, National Association, as trustee (the “2017-BNK4
Trustee”), and Pentalpha Surveillance LLC, as operating advisor and as asset representations reviewer, and that the
2017-BNK4 Trustee is the holder of the Subject Mortgage Loan.

 

The
undersigned, as 2017-BNK4 Certificate Administrator, hereby directs you, in your capacity as the Lead Servicer of the Subject
Whole Loan, to remit to the 2017-BNK4 Master Servicer all amounts payable to, and forward, deliver or otherwise make available,
as the case may be, to the 2017-BNK4 Master Servicer all reports, statements, documents, communications, and other information
that are to be forwarded, delivered or otherwise made available to, the holder of the Subject Mortgage Loan under the related
Intercreditor Agreement (as such term is defined in the 2017-BNK4 Pooling and Servicing Agreement) and the PSA.

 

The
Subject Mortgage Loan is not a Significant Obligor (as such term is defined in the 2017-BNK4 Pooling and Servicing Agreement)

                                         ____________________

 

Reference
is made to the Pooling and Servicing Agreement described above. Capitalized terms used but not defined herein have the meanings
assigned to such terms in the Pooling and Servicing Agreement.

 

As
Master Servicer under the Pooling and Servicing Agreement, we hereby:

 

(a)   Notify
you that the Mortgagor has consummated a defeasance of the Mortgage Loan pursuant to the terms of the Mortgage Loan, of the type
checked below:

 

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

 

____ a
partial defeasance of a portion of the principal balance of the Mortgage Loan that represents and, an allocated loan amount of
$____________ or _______% of the entire principal balance of the Mortgage Loan;

 

(b)  Certify
that each of the following is true, subject to those exceptions set forth with explanatory notes on Exhibit A hereto, which
exceptions the Master Servicer has determined, consistent with the Servicing Standards, will have no material adverse effect on
the Mortgage Loan or the defeasance transaction:

 

(i)     The
Mortgage Loan documents permit the defeasance, and the terms and conditions for defeasance specified therein were satisfied in
all material respects in completing the defeasance.

 

(ii)    The
defeasance was consummated on __________, 20__.

 

(iii)  The
defeasance collateral consists of securities that (i) constitute “government securities” as defined in Section 2(a)(16)
of the Investment Company Act of 1940 as amended (15 U.S.C. 80A1), (ii) are listed as “Qualified Investments for ‘AAA’
Financings” under Paragraphs 1, 2 or 3 of “Cash Flow Approach” in Standard & Poor’s Public Finance
Criteria 2000, as amended to the date of the defeasance, (iii) if they include a principal obligation, the principal due at maturity
cannot vary or change, and (iv) are not subject to prepayment, call or early redemption.

 

(iv) 
 The Master Servicer received an opinion of counsel (from counsel approved by the Master Servicer in accordance with the
Servicing Standard) that the defeasance will not result in an Adverse REMIC Event.

 

    Exhibit U-2

     

    

 

(v)    The
Master Servicer determined that the defeasance collateral will be owned by an entity (the “Defeasance Obligor”)
that is a Single-Purpose Entity (as defined in Standard & Poor’s Structured Finance Ratings Real Estate Finance Criteria,
as amended to the date of the defeasance (the “S&P Criteria”)) or is subject to restrictions in its organizational
documents substantially similar to those contained in the organization documents of the original Borrower with respect to bankruptcy
remoteness and single purpose as of the date of the defeasance, and after the defeasance owns no assets other than the defeasance
collateral and real property securing Mortgage Loans included in the pool.

 

(vi) 
 The defeasance documents require the crediting of the defeasance collateral to an Eligible Account (as defined in the S&P
Criteria) in the name of the Trustee on behalf of the Trust, which account is maintained as a securities account by a securities
intermediary and has been pledged to the Trustee on behalf of the Trust.

 

(vii)  The
agreements executed in connection with the defeasance (i) grant control of the pledged securities account to Trustee on behalf
of the Trust, (ii) require the securities intermediary to make the scheduled payments on the Mortgage Loan from the proceeds of
the defeasance collateral directly to the Master Servicer’s collection account in the amounts and on the dates specified
in the Mortgage Loan documents or, in a partial defeasance, the portion of such scheduled payments attributed to the allocated
loan amount for the real property defeased, increased by any defeasance premium specified in the Mortgage Loan documents (the
“Scheduled Payments”), (iii) permit reinvestment of proceeds of the defeasance collateral only in Permitted
Investments (as defined in the Pooling and Servicing Agreement or as defined in the documents evidencing the defeasance), (iv)
permit release of surplus defeasance collateral and earnings on reinvestment from the pledged securities account only after the
Mortgage Loan has been paid in full, if any such release is permitted, (v) prohibit transfers by the Defeasance Obligor of the
defeasance collateral and subordinate liens against the defeasance collateral, and (vi) provide for payment from sources other
than the defeasance collateral or other assets of the Defeasance Obligor of all fees and expenses of the securities intermediary
for administering the defeasance and the securities account and all fees and expenses of maintaining the existence of the Defeasance
Obligor.

 

(viii)  The
Master Servicer received written confirmation from a firm of independent certified public accountants, who were approved by the
Master Servicer in accordance with the Servicing Standard stating that (i) revenues from the defeasance collateral (without taking
into account any earnings on reinvestment of such revenues) will be sufficient to timely pay each of the Scheduled Payments after
the defeasance including the payment in full of the Mortgage Loan (or the allocated portion thereof in connection with a partial
defeasance) on its Maturity Date (or, in the case of an ARD Loan, on its Anticipated Repayment Date), (ii) the revenues received
in any month from the defeasance collateral will be applied to make Scheduled Payments within four (4) months after the date of
receipt, and (iii) interest income from the defeasance collateral to the Defeasance Obligor in any calendar or fiscal year will
not exceed such Defeasance Obligor’s interest expense for the Mortgage Loan (or the allocated portion thereof in a partial
defeasance) for such year.

 

    Exhibit U-3

     

    

 

(ix)   The
Mortgage Loan is not among the ten (10) largest loans in the pool as of the date of the Current Report (as defined below). The
entire principal balance of the Mortgage Loan as of the date of defeasance was less than both $[______] and five percent of pool
balance, which is less than [__]% of the aggregate Certificate Balance of the Certificates as of the date of the most recent Distribution
Date Statement received by us (the “Current Report”).

 

(x)    The
Master Servicer has received opinions of counsel stating that the Trustee on behalf of the Trust possesses a valid, perfected
first priority security interest in the defeasance collateral and that the documents executed in connection with the defeasance
are enforceable in accordance with their respective terms.

 

(c)    Certify
that Exhibit B hereto is a list of the material agreements, instruments, organizational documents for the Defeasance Obligor,
and opinions of counsel and independent accountants executed and delivered in connection with the defeasance.

 

(d)   Certify
that the individual under whose hand the Master Servicer has caused this Notice and Certification to be executed did constitute
a Servicing Officer as of the date of the defeasance described above.

 

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

 

(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.

(including related net present value calculations and Appraisal Reduction 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 review each
page of the Special Servicer’s policy and procedure manuals (including amendments and appendices), re-engineer the quantitative
aspects of their net present value calculator, visit any property, visit the Special Servicer, visit the Directing Certificateholder
or interact with any borrower. In addition, our review of the net present value calculations and Appraisal Reduction 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 April 1, 2017 (the “Pooling
and Servicing Agreement”), among the Wells Fargo Commercial Mortgage Securities, Inc., as Depositor, Wells Fargo
Bank, National Association, as Master Servicer, Rialto Capital Advisors, LLC, as Special Servicer, Wells Fargo Bank, National Association,
as Certificate Administrator, Wilmington Trust, National Association, as Trustee, and Pentalpha Surveillance LLC, as Operating
Advisor and as Asset Representations Reviewer. Defined terms used herein and not otherwise defined shall have the meanings set
forth in the Pooling and Servicing Agreement.

 

[Wells Fargo Bank, National Association
(“Wells Fargo”)/Rialto Capital Advisors, LLC (“Rialto”)] understands that [____] (the “Company”)
is requesting certain confidential or non-public information relating to the Mortgage Loans to which the Company has continuing
rights as a Certificateholder. The Company is requesting such information for the purpose of analyzing asset performance and evaluating
any continuing rights the Company may have under the Trust (the “Permitted
Purpose”). The Company agrees that the Permitted Purpose shall not include the use or disclosure of the Confidential
Information (as defined below) in any manner that violates any applicable law, the Pooling and Servicing Agreement or the related
mortgage loan documents.

 

[Wells Fargo/Rialto] will provide the Company
with certain confidential, non-public servicing information (the “Confidential
Information”) pertaining to the Mortgage Loans and the related Mortgaged Properties and borrowers. The Company
acknowledges that the Confidential Information (a) includes or may be based upon information provided to [Wells Fargo/ Rialto]
by third parties, (b) may not have been verified by [Wells Fargo/Rialto], and (c) may be incomplete or contain inaccuracies. The
Company agrees that [Wells Fargo/ Rialto], the [“Master

[_____] [__], 20[__]

Page 2

 

Servicer”/”Special Servicer”] (as
defined in the Pooling and Servicing Agreement) and its respective Representatives (as defined below) shall not have any liability
to the Company or its Representatives resulting from (x) any inaccuracies or omissions in the Confidential Information, (y) any
use of the Confidential Information, or (z) [Wells Fargo/ Rialto]’s failure or inability to provide the Confidential Information
to the Company for any reason. Notwithstanding the foregoing, the following will not constitute “Confidential
Information” for purposes of this letter agreement: (a) information that was already in Company’s possession
prior to its receipt from [Wells Fargo/Rialto]; (b) information that is obtained by Company from a third person who, insofar as
is known to Company, is not prohibited from transmitting the information to Company by a contractual, legal or fiduciary obligation
to [Wells Fargo/ Rialto]; (c) information that is or becomes publicly available through no fault of Company; and (d) information
that is independently developed by Company. The term “Representatives” with respect to any entity shall mean the officers,
directors, general partners, employees, agents, affiliates, auditors and legal counsel (which may be internal counsel) of that
entity.

 

The Company may have access to the Confidential
Information through (at [Wells Fargo/Rialto]’s election): (i) responses to reasonable written inquiries received from the
Company, (ii) conference calls conducted on a reasonably scheduled basis with [Wells Fargo/ Rialto]’s surveillance group,
or (iii) direct on-line access (read-only capacity) to the information available on the applicable [____] system or any successor
or replacement system (“System”).
[Wells Fargo/ Rialto] may cease or defer providing the Company with Confidential Information in the event that (a) the Company
or its Representatives violate any provision hereof, or (b) [Wells Fargo/ Rialto] determines (in its sole discretion) that such
termination is necessary for any reason, including its determination that such action is required pursuant to the terms of the
Pooling and Servicing Agreement, the related Mortgage Loan documents, or any applicable law. [Wells Fargo/Rialto] shall cease to
provide the Company with Confidential Information if [Wells Fargo/Rialto] has actual knowledge that the Company or its Representatives
are affiliates of any borrower under the Mortgage Loan documents and [Wells Fargo/Rialto] determines that the provision, notice
or access to such Confidential Information would violate the accepted servicing practices or servicing standards as defined in
the Pooling and Servicing Agreement. The Company’s obligations and the restrictions applicable to the protection of the Confidential
Information hereunder shall survive the termination of the Company’s access to the Confidential Information. [Wells Fargo/
Rialto]’s remedies hereunder, at law or at equity, are cumulative and may be combined.

 

The Company agrees that it will not, and
it shall not permit its Representatives, to disclose the Confidential Information in any manner whatsoever to any other person
or entity, other than its Representatives (but only to the extent necessary to accomplish the Permitted Purpose) who have a need
to know the information, or as otherwise required by applicable law, court order or any governmental agency or regulator. The Company
acknowledges (i) its obligations under the U.S. federal securities laws, and (ii) that any disclosure of the Confidential Information
by it or its Representatives for any purpose other than a Permitted Purpose, in addition to being a breach of this letter agreement,
may constitute a violation of federal and state securities laws. The Company will take reasonable measures to ensure that each
Representative is advised of this letter agreement and agrees to keep the Confidential Information confidential. The Company shall
be liable for any breach of this letter agreement by its Representatives. Notwithstanding the foregoing, the Company may subsequently
provide all or any part of such Confidential

Information to any other person or entity that holds or is contemplating the purchase
of any Certificate or interest therein, but only if such person or entity confirms such ownership interest or prospective ownership
interest and provided that, prior to the delivery of such Confidential Information, such persons shall have executed and
delivered to the Company an agreement that is substantially similar in form and substance to this agreement.

 

This letter agreement shall be governed
by and construed in accordance with the laws of the State of New York without the application of conflict of laws principles. Anything
herein to the contrary notwithstanding, [Wells Fargo/Rialto] intends at all times to comply with the terms and provisions of the
Pooling and Servicing Agreement and nothing in this letter agreement should be construed to limit or qualify any of [Wells Fargo/Rialto]’s
rights or obligations under the Pooling and Servicing Agreement. This letter agreement may be executed in counterparts and by facsimile/Portable
Document Format (PDF); each such counterpart shall be deemed to be an original instrument, and all such counterparts together shall
constitute one agreement.

 

This agreement shall terminate with respect
to the information received by the Company one year after the Company receives such information or ceases to be a Certificateholder.
Company agrees that this letter agreement supersedes and replaces and survives any click-through agreement regarding confidentiality
of Confidential Information agreed to in connection with accessing the System whether agreed to in accessing the System before
or after signing this letter agreement.

ASSET
REVIEW PROCEDURES

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

    BANK 2017-BNK4
 PP-1

     

    

 

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

 

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

The Mortgage Loan Seller has full right and authority to sell, assign and transfer each Mortgage Loan, and the assignment to the Depositor constitutes a legal, valid and binding assignment of such Mortgage Loan free and clear of any and all liens, pledges, charges or security interests of any nature encumbering such Mortgage Loan.	2a	Review the amounts listed on the original Mortgage Note and Mortgage for an indication that they match the amounts listed on the Mortgage Loan Schedule.

or scenario expected loss (“PML”) for the Mortgaged Property in the event of an earthquake. In such instance,
the PML was based on a 475 year return period, an exposure period of 50 years and a 10% probability of exceedance. If the resulting

losses in excess of 5% of then-outstanding principal amount of the related Mortgage Loan, the Mortgagee (or a trustee appointed
by it) having the right to hold and disburse such proceeds as the repair or restoration progresses, or (b) to the payment of the
outstanding principal balance of such Mortgage Loan together with any accrued interest thereon.

and assigns as a loss payee under a mortgagee endorsement clause or, in the case of the general liability insurance policy, as
named or additional insured. Such insurance policies will inure to the benefit of the trustee. Each related Mortgage Loan obligates
the related Mortgagor to maintain all such insurance and, at such Mortgagor’s failure to do so, authorizes the Mortgagee
to maintain such insurance at the Mortgagor’s cost and expense and to charge such Mortgagor for related premiums. All such
insurance policies (other than commercial liability policies) require at least 10 days’ prior notice to the Mortgagee of

    conditions specified in the Mortgage Loan documents; (ii) the Mortgage Loan cannot be defeased within two years after the
    Closing Date; (iii) the Mortgagor is permitted to pledge only United States “government securities” within the

    payments under the Mortgage Loan when due, including the entire remaining principal balance on the maturity date (or on or
    after the first date on which payment may be made without payment of a Yield Maintenance Charge or Prepayment Premium) or,
    if the Mortgage Loan is an ARD Loan, the entire principal balance outstanding on the Anticipated Repayment Date (or on or
    after the first date on which payment may be made without payment of a Yield Maintenance Charge or Prepayment Premium), and
    if the Mortgage Loan permits partial releases of real property in connection with partial defeasance, the revenues from the
    collateral will be sufficient to pay all such scheduled payments calculated on a principal amount equal to a specified percentage
    at least equal to 110% of the allocated loan amount for the real property to be released; (iv) the defeasance collateral is
    not permitted to be subject to prepayment, call, or early redemption; (v) the Mortgagor is required to provide a certification
    from an independent certified public accountant that the collateral is sufficient to make all scheduled payments under the
    Mortgage Note as set forth in clause (iii) above; (vi) the defeased note and the defeasance collateral are required to be
    assumed by a Single-Purpose Entity; (vii) the Mortgagor is required to provide an opinion of counsel that the Trustee has
    a perfected security interest in such collateral prior to any other claim or interest; and (viii) the Mortgagor is required
    to pay all rating agency fees associated with defeasance (if rating confirmation is a specific condition precedent thereto)
    and all other reasonable expenses associated with defeasance, including, but not limited to, accountant’s fees and opinions

                                         Ground Leases. For purposes of these representations and warranties, a “Ground
                                         Lease” shall mean a lease creating a leasehold estate in real property where
                                         the fee owner as the ground lessor conveys for a term or terms of years its entire interest
                                         in the land and buildings and other improvements, if any, comprising the premises demised
                                         under such lease to the ground lessee (who may, in certain circumstances, own the building

        upon the terms of the Ground Lease and any estoppel or other agreement received from the ground lessor in favor of Mortgage
        Loan Seller, its successors and assigns (collectively, the “Ground Lease and Related Documents”), Mortgage

        Ground Lease or a memorandum regarding such Ground Lease has been duly recorded or submitted for recordation in a form
        that is acceptable for recording in the applicable jurisdiction. The Ground Lease and Related Documents permit the interest
        of the lessee to be encumbered by the related Mortgage and do not restrict the use of the related Mortgaged Property by
        such lessee, its successors or assigns in a manner that would materially adversely affect the security provided by the
        related Mortgage. No material change in the terms of the Ground Lease had occurred since its recordation, except by any
        written instruments which are included in the related Mortgage File;

         

        (B)       The

                                         there is no material default under such Ground Lease and no condition that, but for the
                                         passage of time or giving of notice, would result in a material default under the terms

    has been originated within the past 12 months), and as of Cut-off Date, no Mortgage Loan is delinquent (beyond any applicable

    (other than payments due but not yet delinquent) which, with the passage of time or with notice and the expiration of any

    Loan has been originated within the past 12 months), or (ii) the Mortgage Loan was delinquent beyond any applicable grace
    or cure periods as of the Cut-off Date. If no such notation is found, it will be a Test pass.	Collective
