Note
A-A-1-A 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-1-B, Note A-A-2, Note A-A-3, Note A-A-4, Note A-A-5, Note A-A-6, Note A-A-7, Note A-A-8, Note A-A-9,
Note A-A-10 are collectively referred to herein as the “Non-Trust A Notes” or the “Senior Non-Trust
Notes”. The Trust A Note and the Non-Trust A Notes 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-1-A, Note B-1-B and Note
B-2 are referred to herein as the “Non-Trust B Notes”. The Non-Trust B Notes and the Non-Trust A Notes are
referred to herein as the “Non-Trust Notes” or the “Companion Notes”.


 


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 $94,496,000. The portion of the Whole Loan evidenced by Note A-A-5, Note
A-A-6, Note A-A-7, Note A-A-8, Note A-A-9 and Note A-A-10 is referred to as herein as the “UBS 2017-C7 Companion Loan”,

(the “Loan Purchase Agreement”). The Companion Loans will not be assets of the Trust.


 






     


     


    

 


The

2017, between NREC, as holder of the Trust Note, and NREC, as holder of the Companion Notes (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,
Class B, Class C and Class D Regular Interests will represent “regular interests” in the Upper-Tier REMIC. The Class
LA, Class LB, Class LC and Class LD 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, Class B, Class C, Class D 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 and Class LD 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.

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 Note 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).

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


 






    -67-


     


    

 


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.


 


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


 






    -68-


     


    

 


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, 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 Custodial Certificate
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


 






    -69-


     


    

 


Custodial Certificate 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.


 


(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


 






    -70-


     


    

 


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 2018-OSS, Commercial Mortgage Pass-Through Certificates, Series 2018-OSS 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 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


 






    -77-


     


    

 


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.

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
Notes) (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

institutional commercial mortgage lenders in servicing their own loans, or (b) with the care, skill, prudence and diligence

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 Loan Seller, any
Companion Loan Holder or any of their respective affiliates;


 


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


 


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


 






    -78-


     


    

 


(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.


 


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


 






    -79-


     


    

 


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 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.


 






    -80-


     


    

 


(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 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 or in respect
of the Whole Loan, and the making of remittances, to the Trust, as holder of the Trust Loan, and to the Companion Loan Holders,
as holders of the Companion Loans; (ii) with respect to the allocation of expenses and losses relating to the Whole Loan to the
Trust, as holder of the Trust Loan, and to the Companion Loan Holders, as holders of the Companion Loans, and (iii) to the extent
provided for under the Co-Lender Agreement, the consultation rights of the Companion Loan Holders. In the event of 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.

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 by an
insurance policy or deducted from the proceeds of liquidation;


 


(vii)       (A)
to pay to the Servicer, as additional compensation, to the extent actually received from the Borrower, any payments (if any) in
the nature of Default Interest (to the extent not withdrawn to reimburse the Trustee or the Servicer (or the Other Trustee or
Other Servicer with respect to each Senior Companion Loan Securitization Trust) for unpaid interest on any Advances pursuant to
clause (ii) or (v)(B) above), late payment fees (to the extent not withdrawn to reimburse the Trustee or the Servicer for unpaid
interest on any Advances pursuant to clause (ii) or (v)(B) above), Additional Servicing Compensation including, but not limited
to, assumption fees, assumption application fees, defeasance fees, substitution fees, Modification Fees, transfer fees, consent
fees, loan service transaction fees and similar fees and expenses which the Servicer is entitled to pursuant to Section 3.17;
provided, however, that such amounts received during each Collection Period shall be deemed to have been deposited
in the Collection Account and withdrawn 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


 






    -84-


     


    

 


Compensation and (ii) any income earned
on the investment of funds deposited in the Foreclosed Property Account;


 


(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 Loans 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 


 



    -85-


     


    

 


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
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 Note 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.


 


On
the Closing Date, the Depositor shall remit to the Certificate Administrator for deposit into the Interest Reserve Account an
amount equal to the aggregate Interest Deposit Amount. On or prior to the Remittance Date in March 2018, the Certificate Administrator
shall transfer to the Lower-Tier Distribution Account the Interest Deposit Amount on deposit in the Interest Reserve 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


 






    -86-


     


    

 


the benefit of the Senior Companion Loan Account) to the Senior Companion
Loan Holders in accordance with the amounts due to such holder under the terms of the Co-Lender Agreement.


 


(f)          In
addition, the Servicer shall withdraw from the Collection Account (or any subaccount thereof established for the benefit of the
Senior Companion Loan Account) and remit to the holder of each Senior Companion Loan, within one (1) Business Day of receipt of
properly identified funds, any amounts that represent late collections or principal prepayments on such Senior Companion Loan
or any successor REO Property with respect thereto (exclusive of any portion of such amount payable or reimbursable to any third
party in accordance with the Co-Lender Agreement), unless such amount would otherwise be included in such distributions on or
before the Remittance Date pursuant to Section 3.4(c); provided, however, that to the extent any such amounts are received
after 3:00 p.m. Eastern time on any given Business Day, the Servicer shall use efforts consistent with Accepted Servicing Practices
to remit such late collections or principal prepayments to the holder of each Senior Companion Loan within one Business Day of
receipt of such properly identified funds but, in any event, the Servicer shall remit such amounts within two Business Days of
receipt of such properly identified funds.


 


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 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);


 






    -87-


     


    

 


(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:


 


(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 2018-OSS, Commercial Mortgage Pass-Through Certificates, Series
2018-OSS” 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),


 






    -88-


     


    

 


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 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-2 Note, up to the full outstanding
principal balance thereof, then, to the Non-Trust B-1-B Note, up to the full outstanding principal balance thereof, then,
to the Non-Trust B-1-A 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


 






    -89-


     


    

 


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 D Certificates; second, to the Class
C Certificates; and third, 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-AB Certificates and the Class V2
Certificates, pro rata in proportion to the Class A Percentage Interest, the Class V1-AB 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-AB Certificates and the Class V2
Certificates, pro rata in proportion to the Class B Percentage Interest, the Class V1-AB 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; and


 


(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.


 


(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


 






    -90-


     


    

 


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 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 D 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 D 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


 






    -91-


     


    

 


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 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


 






    -92-


     


    

 


(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 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


 






    -93-


     


    

 


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 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 Holders 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


 






    -94-


     


    

 


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) 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


 






    -95-


     


    

 


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.


 


(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;


 






    -96-


     


    

 


(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 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


 






    -97-


     


    

 


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.


 


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


 






    -98-


     


    

 


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 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


 






    -99-


     


    

 


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 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 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 efforts consistent with Accepted Servicing Practices 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


 






    -100-


     


    

 


parent) is rated at least “A-”
by S&P (or, if not so rated, as otherwise acceptable to S&P 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 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


 






    -101-


     


    

 


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 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 Agency 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, 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.


 


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.


 






    -102-


     


    

 


(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


 


(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 Loans) 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 Loans immediately
after any discharge is equal to the unpaid principal balance of the Trust Loan and Companion Loans, 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 2018-OSS, Commercial Mortgage Pass-Through Certificates, Series 2018-OSS
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 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


 






    -104-


     


    

 


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.


 


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


 






    -105-


     


    

 


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, 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


 






    -106-


     


    

 


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 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


 






    -107-


     


    

 


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.


 


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 right of the holder of Note B-2 (if a Note B-2 Control Appraisal Period is not continuing), the right of the holder
of Note B-1-B (if a Note B-2 Control Appraisal Period is continuing, but a Note B-1-B Control Appraisal Period is not continuing),
or the right of the holder of Note B-1-A (if a Note B-2 Control Appraisal Period and a Note B-1-B Control Appraisal Period are
continuing, but a Note B-1-A Control Appraisal Period is not continuing), as applicable, 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 Holders, 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


 






    -108-


     


    

 


Section 8.14(b).
The Companion Loans 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, 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 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 Notes). 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.


 






    -109-


     


    

 


(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
the terms of a workout arrangement or (iii) the Defaulted Loan has otherwise been resolved (including by a full or discounted
pay-off).


 


(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 Loans) 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 Loans.


 


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


 






    -110-


     


    

 


“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, transfer 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 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


 






    -111-


     


    

 


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 or (c) the purchase of the Trust Loan by a 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 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, transfer 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.


 






    -112-


     


    

 


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 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


 






    -113-


     


    

 


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 Borrower 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.

The
CREFC® Operating Statement Analysis Report and the CREFC® NOI Adjustment Worksheet shall be delivered

Administrator on a calendar quarterly basis within 30 days after the Servicer’s receipt of the Borrower’s quarterly

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, 2018.


 


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 Day immediately preceding each Distribution Date; provided, however, that the Servicer
shall have no obligation to update such reports except as set forth in the immediately preceding paragraph and no analysis or

CREFC® guidelines. With respect to the Companion Loans, 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 a 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 Loans included in the CREFC®

reasonable request. The Servicer shall provide any templates relating to the Companion Loans 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

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).


 






    -115-


     


    

 


(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 an itemized listing of any Disclosable Special Servicer Fees received by the Special Servicer or any of its Affiliates

3.19.          [Reserved]


 


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 Agency). 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 Agency, 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 Agency (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 2019, 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


 






    -116-


     


    

 


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


 






    -117-


     


    

 


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 each Other
Servicer, Other Special Servicer and Other Trustee 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 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


 






    -118-


     


    

 


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 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 Notes) 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


 






    -119-


     


    

 


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 related
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 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 Holders and (viii) any Other
Servicer, Other Special Servicer and Other Trustee under each related Other Pooling and Servicing Agreement (for purposes of clause
(vii) and clause (viii) 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


 






    -120-


     


    

 


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 Loans (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 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 Loans or (vii) subordinated obligations, including the Junior Companion Loans.


 


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,


 






    -121-


     


    

 


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 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 the 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


 






    -122-


     


    

 


shall act as a successor mortgagor, if so required by
the Rating Agency, (v) to the extent permissible under the Loan Documents, the Servicer shall use efforts consistent with Accepted
Servicing Practices 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 the 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. 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
the 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 the Rating Agency for such Rating Agency
Confirmation or written confirmation and, within 10 Business Days of such request being sent to the Rating Agency, the Rating
Agency has not replied to such request or has responded in a manner that indicates that the 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 the 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 the 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): if the


 






    -123-


     


    

 


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.


 


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 the 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 Loans. 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


 






    -124-


     


    

 


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 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.


 






    -125-


     


    

 


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 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


 






    -126-


     


    

 


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 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.


 






    -127-


     


    

 


(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.


 


(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


 






    -128-


     


    

 


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 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.


 






    -129-


     


    

 


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.

or reimbursement of Realized 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.


 


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.


 






    -135-


     


    

 


(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


 


(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


 






    -136-


     


    

 


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 Regular Interests) in the following order:


 


first,
to the Class D Regular Interest;


 


second,
to the Class C Regular Interest;


 


third,
to the Class B Regular Interest; and


 


fourth,
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 Regular Interests)
(or portion thereof) that corresponds to a Class X Component shall result in a corresponding reduction in the Notional Amount
of the Class X Regular Interest, as applicable, on the same Distribution Date. Allocations of Realized Losses to any Class of
Regular Interests (other than the Class X 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-AB Certificates and the Class V2
Certificates, pro rata in proportion to the Class A Percentage Interest, the Class V1-AB 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-AB Certificates and the Class V2
Certificates, pro rata in proportion


 






    -137-


     


    

 


to the Class B Percentage Interest, the Class V1-AB 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; and


 


(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.


 


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, and fourth, to the Class D 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


 






    -138-


     


    

 


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.          Allocation
and Distribution of Yield Maintenance Premiums. (a) On any Distribution Date, any Yield Maintenance Premiums
collected in respect of the Trust Loan during the related Collection Period shall be distributed to the holders of each Class
of Certificates (other than the Class R Certificates) in the following manner: (i) the Certificateholders of each Class of
Sequential Pay Certificates shall be entitled to receive on each Distribution Date, an amount of Yield Maintenance Premiums
for the Trust Loan prepayments, in an amount equal to the product of (x) a fraction whose numerator is the amount of
principal distributed to such Class on such Distribution Date and whose denominator is the total amount of principal
distributed to all of the Certificates representing principal payments collected in respect of the Trust Loan on such
Distribution Date, (y) the Base Interest Fraction for the related principal prepayment on such Class of Certificates, and (z)
the Yield Maintenance Premiums collected during the related Collection Period; and (ii) any Yield Maintenance Premiums
collected during the related Collection Period remaining after such distributions will be further distributed as follows: to
the Class X Certificates, in an amount equal to the product of (1) a fraction whose numerator is the amount of principal
distributed to the Class A Certificates on such Distribution Date and whose denominator is the total amount of principal
distributed to all of the Certificates representing principal payments in respect of the Trust Loan on such Distribution
Date, and (2) the Yield Maintenance Premium collected during the related Collection Period, minus (b) the amount of Yield
Maintenance Premium distributable to the Class A, Class B, Class C and Class D Certificates on such Distribution Date. If
there is more than one such Class of Certificates entitled to distributions of principal on any particular Distribution
Date on which Yield Maintenance Premiums are distributable, the aggregate amount of such Yield Maintenance Premiums shall be
allocated among all such Classes of Certificates up to, and on a pro rata basis in accordance with, their respective
entitlements thereto in accordance with the first sentence of this paragraph. For the avoidance of doubt, the Class X
Certificates shall not be entitled to any Yield Maintenance Premiums after their respective Notional Amounts has been reduced
to zero.


 


(b)          All
Yield Maintenance Premiums distributable pursuant to Section 4.3(a) shall first be deemed to have been distributed from
the Lower-Tier REMIC to the Upper-Tier REMIC in respect of the Class LA Uncertificated Interest (whether or not the Lower-Tier
Principal Amount of such Uncertificated Lower-Tier Interest has been reduced to zero) and form the Upper-Tier REMIC to the Grantor
Trust in respect of the related Classes of Regular Interests.


 


(c)          On
each Distribution Date, any Yield Maintenance Premiums distributed in respect of:


 


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


 


(ii)         the
Class X Regular Interest shall be further allocated between and distributed on the Class X Certificates, Class V1-AB Certificates

and the Class V2 Percentage Interest, respectively;

Class B Regular Interest shall be further allocated between and distributed on the Class B Certificates, the Class V1-AB Certificates
and the Class V2 Certificates, pro rata in proportion to the Class B Percentage Interest, the Class V1-AB Percentage Interest
and the Class V2 Percentage Interest, respectively;


 


(iv)        the
Class C Regular Interest shall be further allocated between and distributed on 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; and


 


(v)         the
Class D Regular Interest shall be further allocated between and distributed on 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.

or the Risk Retention Consultation Party, or otherwise to consult with the party from whom such Inquiry or answer is received
to confirm the same, and the Certificate Administrator shall have no liability in connection with its posting to the Investor

and in integral multiples of 1% in excess thereof.

shall be conclusive evidence that the Certificate has been executed and countersigned under this Agreement.


 


5.2.          Form

office, as custodian, for the Depository, and registered in the name of the Depository or the nominee of the Depository for

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 Global Certificate may be held only through Euroclear
or Clearstream. After the expiration of the Restricted Period, a beneficial interest in a Temporary Regulation S Global
Certificate may be exchanged for an interest in the related permanent global certificate of the same Class (a
“Regulation S Global Certificate”) in the applicable form set forth as an exhibit hereto in accordance
with the procedures set forth in Section 5.3(f). During the Restricted Period, distributions due in respect of a
beneficial interest in a Temporary Regulation S Global 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 Global
Certificate shall not be made to the holders of such beneficial interests unless exchange for a beneficial interest in the
Regulation S Global Certificate of the same Class is improperly withheld or refused. The aggregate Certificate Balance of a
Temporary Regulation S Global Certificate or a Regulation S Global 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.

the “Global Certificates”), which shall be deposited with the Certificate Registrar or an agent of the Certificate

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

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

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.

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


 






    -151-


     


    

 


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 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.


 






    -152-


     


    

 


(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 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)          The
Class R Certificate may not 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. Each prospective
transferee of the Class R Certificate 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, Class B, Class C, Class D, Class V1-AB, Class V1-C, Class
V1-D or Class V2 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:


 






    -153-


     


    

 


(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.


 


(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


 






    -154-


     


    

 


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.


 


(p)          Each
beneficial owner of a Certificate or any interest therein that is a Plan subject to Title I of ERISA or Section 4975 of the Code
(an “ERISA Plan”), including any fiduciary purchasing Certificates on behalf of an ERISA Plan (“Plan
Fiduciary”), will be deemed to have represented by its acquisition of such Certificates that:


 


(i)          none
of the Depositor, the Initial Purchaser, the Trustee, the Certificate Administrator, the Servicer, the Special Servicer or any
of their respective affiliated entities (the “Transaction Parties”), has provided or will provide advice with
respect to the acquisition of Certificates by the ERISA Plan, other than to the Plan Fiduciary which is independent of the Transaction
Parties, and the Plan Fiduciary either: (a) is a bank as defined in Section 202 of the Investment Advisers Act of 1940 (the “Advisers

ERISA Plan is invested in the Certificates will have, total assets of at least U.S. $50,000,000 under its management or control
(provided that this clause (e) shall not be satisfied if the Plan Fiduciary is either (i) the owner or a relative of the owner
of an investing individual retirement account or (ii) a participant or beneficiary of the ERISA Plan investing in the Certificates
in such capacity);


 


(ii)         the
Plan Fiduciary is capable of evaluating investment risks (ii) independently, both in general and with respect to particular transactions
and investment strategies, including the acquisition by the ERISA Plan of Certificates;


 






    -155-


     


    

 


(iii)        the
Plan Fiduciary is a “fiduciary” with respect to the ERISA Plan within the meaning of Section 3(21) of ERISA, Section
4975 of the Code, or both, and is responsible for exercising independent judgment in evaluating the ERISA Plan’s acquisition
of the Certificates;


 


(iv)        none
of the Transaction Parties has exercised any authority to cause the ERISA Plan to invest in the Certificates or to negotiate the
terms of the ERISA Plan’s investment in the Certificates or receives a fee or other compensation from the ERISA Plan or
the Plan Fiduciary for the provision of investment advice in connection with the acquisition by the ERISA Plan of the Certificates;
and


 


(v)         the

otherwise made a recommendation, in connection with the ERISA Plan’s acquisition of the Certificates; and (b) of the existence
and nature of the Transaction Parties’ financial interests in the ERISA Plan’s acquisition of the Certificates.


 


The
above representations are intended to comply with the DOL’s Reg. Sections 29 C.F.R. 2510.3-21(a) and (c)(1) as promulgated
on April 8, 2016 (81 Fed. Reg. 20,997). If these regulations are revoked, repealed or no longer effective, these representations
shall be deemed to be no longer in effect.


 


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 distributed to Certificateholders has been provided an Investor Certification, such party to this


 






    -156-


     


    

 


Agreement

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,

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

    -157-


     


    

 


(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-AB Certificates shall represent beneficial ownership
interests in the Class V1-AB Percentage Interest of the Class A, Class B and Class X Regular Interests. At all times, the Class
V1-C Certificates shall represent beneficial ownership interests in the Class V1-C Percentage Interest of the Class C Regular
Interests. At all times, the Class V1-D Certificates shall represent beneficial ownership interests in the Class V1-D Percentage
Interest of the Class D Regular Interests. At all times, the Class V2 Certificates shall represent beneficial ownership interests
in the Class V Percentage Interest of the Regular Interests.


 


(b)          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 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.


 


	Exchangeable
    Groups

    C	 	Class
    V1-C	 	 
	Class

    V1-D	 	 







 


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-AB, Class V1-C and Class V1-D Certificates


 






    -158-


     


    

 


(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 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 2018-OSS” 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


 






    -159-


     


    

 


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.

and shall be deemed to have assumed all of the liabilities and obligations of such Servicer or Special Servicer 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 (1) such successor or surviving Person would not cause the then current
rating on any of the Certificates to be qualified, downgraded or withdrawn by the Rating Agency or any Senior Companion Loan Securities
by each rating agency then rating any Senior Companion Loan Securities (each, as evidenced in writing from the Rating Agency and
delivered to the Certificate Administrator and the Trustee and (2) if the Servicer or Special

Servicer enters into a merger and
is the surviving entity under the applicable law, such Servicer or Special Servicer, as applicable, will not, as a result of the
merger, be required to provide a Rating Agency Confirmation.


 


6.3.          Limitation
on Liability of the Depositor, the Servicer, the Special Servicer and Others. (a) Neither the Depositor, the
Servicer, the Special Servicer nor any of their respective directors, officers, members, managers, partners, employees,
Affiliates or agents shall be under any liability to the Trust, the Certificateholders or the Companion Loan Holders for any
action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, actions taken or not
taken at the direction of Certificateholders or the Companion Loan Holders, or for errors in judgment; provided, however,
that this provision shall not protect the Depositor, the Servicer, the Special Servicer or any such other 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 its duties or by reason of negligent disregard of its obligations
and duties hereunder and shall not release the Depositor or its Affiliates from, or otherwise relate to any liability or
obligation of any party to any Loan Document or the Loan Seller under the Loan Purchase Agreement. The Depositor, the
Servicer, the Special Servicer and any of their respective directors, officers, employees, members, managers, partners,
Affiliates or agents may reasonably rely on any document of any kind prima facie properly executed and submitted by any
Person respecting any matters arising hereunder. The Depositor, the Servicer, the Special Servicer and any of their
respective directors, officers, members, managers, partners, employees, agents, Affiliates or other “controlling
persons” within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
(“Controlling Persons”), shall be indemnified by the Trust (in accordance with the procedures set forth in Section
3.4(c)) and held harmless against any loss, liability, claim, demand or expense incurred in connection with any legal
action or other claims, costs, expenses, losses, penalties, fines, foreclosures, judgments or liabilities relating to this
Agreement, the Co-Lender Agreement, the Whole Loan, the Property, or the Certificates (including, without limitation,
reasonable fees and disbursements of counsel incurred in any action or proceeding related thereto) other than any loss,
liability or expense incurred by reason of willful misconduct, bad faith or negligence by it in the performance of its duties
hereunder or by reason of its negligent disregard of its obligations and duties hereunder or for any liability or obligation
of any party to any Loan Document or the Loan Seller under the Loan Purchase Agreement. None of the Depositor, the Servicer
or Special Servicer shall be under any obligation to appear in, prosecute or defend any legal action which is not incidental
to its respective duties under this Agreement and which in its opinion may involve it in any expense or liability; provided, however,
that the Depositor, the Servicer or the Special Servicer may, in its discretion, undertake any such action which it may deem
necessary or desirable in accordance with Accepted Servicing Practices in respect of this Agreement, the Co-Lender Agreement
and the rights and duties of the parties hereto and the interests of the Certificateholders and the Companion Loan Holders
hereunder. In such event, the legal expenses and costs of such action and any liabilities of the Trust, the Depositor, the
Servicer and the Special Servicer shall be entitled to be reimbursed therefor pursuant to Section 3.4(c) from funds on
deposit in the Collection Account; provided that the Servicer shall, after receiving payment from amounts on deposit
in the Collection Account, promptly notify the Companion Loan Holders and use commercially reasonable efforts to exercise on
behalf of the Trust any rights under the Co-Lender Agreement to obtain indemnification and reimbursement for the portion of
such amount allocable to the


 






    -161-


     


    

 


Companion
Loans from the Companion Loan Holders (if permitted under the Co-Lender Agreement).


 


Neither
the Servicer nor the Special Servicer 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 by the Trustee or Certificate Administrator of any funds
paid to the Trustee or the Certificate Administrator, as applicable, in respect of the Trust Loan deposited into or withdrawn
from the Distribution Account or any account (other than the Collection Account and the Foreclosed Property Account and any other
account maintained by the Servicer, the Special Servicer or any Sub-Servicer pursuant to this Agreement) maintained by or on behalf
of the Trustee or the Certificate Administrator (except to the extent that any such account is held by the Servicer or the Special
Servicer in its commercial capacity), or for investment of such amounts (other than investments made with the Servicer or the
Special Servicer in its commercial capacity).


 


(b)          The
Depositor shall not be obligated to monitor or supervise the performance of the Servicer, the Special Servicer, the Trustee or
the Certificate Administrator under this Agreement. The Depositor may, but shall not be obligated to, enforce the obligations
of the Servicer, the Special Servicer, the Trustee and the Certificate Administrator under this Agreement.


 


(c)          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 (the “Applicable Banking Laws”),
the Servicer, the Special Servicer, the Trustee and the Certificate Administrator, as the case may be, may be required to obtain,
verify and record certain information relating to individuals and entities that maintain a business relationship with the Servicer,
the Special Servicer, the Trustee and the Certificate Administrator, as the case may be. Accordingly, each of the parties hereto
agrees to provide to the Servicer, the Special Servicer, the Trustee and the Certificate Administrator upon its respective request
from time to time, such identifying information and documentation as may be available for such party in order to enable the Servicer,
the Special Servicer, the Trustee and the Certificate Administrator, as the case may be, to comply with Applicable Banking Law.


 


6.4.          Servicer
and Special Servicer Not to Resign; Replacement of Servicer or Special Servicer. (a) Each of the Servicer and
Special Servicer may resign and assign its rights and delegate its duties and obligations under this Agreement to any Person
or to an entity, provided that:


 


(i)          the
Person accepting such assignment and delegation (A) shall be an established mortgage finance institution, bank or mortgage servicing
institution having a net worth of not less than $25,000,000, organized and doing business under the laws of the United States
or of any state of the United States or the District of Columbia, authorized under such laws to perform the duties of the Servicer
or the Special Servicer, as the case may be, of the Whole Loan, (B) shall execute and deliver to the Trustee an agreement satisfactory
to the Trustee, which contains an assumption by such Person of the performance and observance of each covenant and condition to
be performed or observed by the Servicer or the Special Servicer, as the case may be, under this


 






    -162-


     


    

 


Agreement from and after the
date of such agreement; provided, however that to the extent such agreement modifies in any respect any of the covenants,
terms or conditions in this Agreement to be performed by the Servicer or the Special Servicer, as the case may be, such agreement
shall be subject to the approval of the Trustee, such approval not to be unreasonably withheld, and (C) shall make such representations
and warranties of the Servicer or the Special Servicer, as the case may be, as provided in Section 2.5;


 


(ii)         Rating
Agency Confirmation has been received with respect to the assignee or appointee of the Servicer or Special Servicer, as applicable;


 


(iii)        the
Servicer or the Special Servicer, as the case may be, shall not be released from its obligations under this Agreement that arose
prior to the effective date of such assignment and delegation under this Section 6.4(a);


 


(iv)        the
rate at which any servicing compensation (or any component thereof) is calculated shall not exceed the rate specified herein;
and


 


(v)         the
Servicer or the Special Servicer, as the case may be, shall reimburse the Trustee, the Certificate Administrator, the Trust, and
the Rating Agency for any expenses of such resignation, assignment, sale or transfer.


 


Upon
satisfaction of the foregoing requirements and acceptance of such assignment, such Person shall be the successor Servicer or the
Special Servicer, as the case may be, hereunder.


 


(b)          Other
than as set forth in Sections 6.2 and 6.4(a), neither the Servicer nor the Special Servicer shall resign from its
obligations and duties hereby imposed on it, except upon determination that performance of its duties hereunder is no longer permissible
under applicable law or are in material conflict by reason of applicable law with any other activities carried on by it. Any such
determination permitting the resignation of the Servicer or the Special Servicer, as the case may be, shall be evidenced by an
Opinion of Counsel delivered to the Trustee, the Depositor and, during any Subordinate Control Period, the Directing Holder. No
resignation by the Servicer or the Special Servicer, as applicable, under this Agreement shall become effective until a successor
Servicer or Special Servicer, as applicable, shall have assumed the responsibilities and obligations of the Servicer or the Special
Servicer, as applicable, under this Agreement in accordance with Section 7.2. Notwithstanding the previous sentence, each
of the Servicer and the Special Servicer may assign its duties and obligations under this Agreement under certain limited circumstances
as described herein.


 


6.5.          Ethical
Wall.


 


The
Servicer and the Special Servicer shall afford the Depositor, upon reasonable advance notice, during normal business hours access
to all non-confidential, non-proprietary records, including those in electronic form, documentation, records or any other information
regarding the Whole Loan that are in its possession or control hereunder and access to its officers responsible therefor. The
Depositor shall not have any responsibility or liability for any action or failure to act by the Servicer or the Special Servicer
and is not obligated to supervise the performance of the Servicer and the Special Servicer under this Agreement or otherwise.

6.6.          Indemnification
by the Servicer, the Special Servicer and the Depositor. (a)          Each of the
Servicer, the Special Servicer and the Depositor, severally and not jointly, shall indemnify and hold harmless the Trust, the
Certificate Administrator, the Companion Loan Holders and the Trustee from and against any claims, losses, damages,
penalties, fines, forfeitures, reasonable legal fees and expenses and related costs, judgments and other costs and expenses
incurred by the Trust, the Certificate Administrator or the Trustee (each, for the purposes of this Section 6.6 only,
an “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 Servicer, the Special Servicer or the Depositor, as the case may be, of its obligations to the Trust or
the Certificateholders under this Agreement or (ii) negligence, bad faith, fraud or willful misconduct on the part of the
Servicer, the Special Servicer or the Depositor, as the case may be, in the performance of such obligations or its negligent
disregard of its obligations and duties under this Agreement.


 


(b)          Each
of the Servicer and the Special Servicer, severally and not jointly, shall indemnify and hold harmless the Companion Loan Holders
from and against any and all claims, losses, damages, penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments, and any other costs and expenses that the Companion Loan Holders may sustain in connection with this Agreement that
arise out of or are based upon the Servicer’s or the Special Servicer’s, as the case may be, willful misconduct, bad
faith or negligence in the performance of its obligations hereunder or by reason of negligent disregard of its obligations hereunder.

7.1.          Servicer
Termination Events; Special Servicer Termination Events. (a) “Servicer Termination Event,” or
“Special Servicer Termination Event” wherever used herein with respect to the Servicer or the Special

    -164-


     


    

 


unremedied for ten Business Days (or such shorter period (not less than two Business Days) as would prevent
a lapse in insurance or a delinquent payment of real estate taxes or ground or leasehold rents) following the date on which the
Servicer receives notice thereof or should have had notice thereof if it had been acting in accordance with Accepted Servicing
Practices;


 


(iii)        any
failure by the Servicer or the Special Servicer, as applicable, to observe or perform in any material respect any other of its
covenants or agreements or the material breach of its representations or warranties under this Agreement, which failure shall
continue unremedied for a period of 30 days after the date on which written notice of such failure shall have been given to the
Servicer or Special Servicer, as applicable, by the Trustee or to the Servicer or Special Servicer, as applicable, and the Trustee
by the holders of Sequential Pay Certificates having greater than 25% of the aggregate Voting Rights of all then outstanding Sequential
Pay Certificates or by a Companion Loan Holder, if affected; provided, however, that, with respect to any such failure
that is not curable within such 30-day period, the Servicer or the Special Servicer, as applicable, will have an additional cure
period of 30 days to effect such cure so long as the Servicer or the Special Servicer, as applicable, has commenced to cure such
failure within the initial 30-day period and has provided the Trustee with an officer’s certificate certifying that it has
diligently pursued, and is continuing to diligently pursue, such cure;


 


(iv)        a
decree or order of a court or agency or supervisory authority having jurisdiction in the premises in an involuntary case under
any present or future federal or state bankruptcy, insolvency or similar law for the appointment of a conservator or receiver
or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the
winding-up or liquidation of its affairs, shall have been entered against the Servicer or the Special Servicer, as applicable,
and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; provided, however,
that, with respect to any such decree or order that cannot be discharged, dismissed or stayed within such 60-day period, the Servicer
or the Special Servicer, as appropriate, will have an additional period of 30 days to effect such discharge, dismissal or stay
so long as it has commenced proceedings to have such decree or order dismissed, discharged or stayed within the initial 60-day
period and has diligently pursued, and is continuing to pursue, such discharge, dismissal or stay;


 


(v)         the
Servicer or the Special Servicer, as applicable, shall consent to the appointment of a conservator or receiver or liquidator or

similar proceedings of or relating to the Servicer or the Special Servicer or of or relating to all or substantially all of its
property;


 


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


 






    -165-


     


    

 


(vii)       the
Servicer or the Special Servicer is no longer listed on S&P’s Select Servicer List as a U.S. Commercial Mortgage Master
Servicer or a U.S. Commercial Mortgage Special Servicer, as applicable, in connection therewith and the Servicer or the Special
Servicer is not reinstated to such status on such list within 60 days;


 


(viii)      a
Senior Companion Loan Rating Agency has (a) qualified, downgraded or withdrawn its rating or ratings of one or more classes of
Senior Companion Loan Securities, or (b) placed one or more classes of Senior Companion Loan Securities on “watch status”
in contemplation of rating downgrade or withdrawal and, in the case of either of clauses (a) or (b), publicly citing
servicing concerns with the Servicer or the Special Servicer, as applicable, as the sole or material factor in such rating action
(and such qualification, downgrade, withdrawal or “watch status” placement has not been withdrawn by such Senior Companion
Loan Rating Agency within sixty (60) days of such event); and


 


(ix)        so
long as a Senior Companion Loan Securitization Trust is subject to the reporting requirements of the Exchange Act, the Servicer
or Special Servicer, as applicable, or any primary servicer, Sub-Servicer or Servicing Function Participant (such entity, the
“Sub-Servicing Entity”) retained by the Servicer or Special Servicer, shall fail to deliver the items required
to be delivered by this Agreement to enable such Senior Companion Loan Securitization Trust to comply with its reporting obligations
under the Exchange Act, the Securities Act or Form SF-3.


 


(b)          Upon
the occurrence of any Servicer Termination Event or Special Servicer Termination Event, the Trustee shall upon actual knowledge
by a Responsible Officer promptly notify the 17g-5 Information Provider and Certificate Administrator in writing and (i) each
of the Certificate Administrator and the 17g-5 Information Provider shall post such notice on its respective Website pursuant
to Section 8.14(b) and (ii) the Certificate Administrator will provide notice of the same to the Certificateholders and
the Senior Companion Loan Holders by mail, to the addresses set forth on the Certificate Register, of such Servicer Termination
Event or Special Servicer Termination Event, unless it shall have been cured or waived. For avoidance of doubt, (i) the occurrence
of a Servicer Termination Event with respect to the Servicer shall not cause there to have occurred a Special Servicer Termination
Event with respect to the Special Servicer unless the relevant event also constitutes a Special Servicer Termination Event and
(ii) the occurrence of a Special Servicer Termination Event with respect to the Special Servicer shall not cause there to have
occurred a Servicer Termination Event with respect to the Servicer unless the relevant event also constitutes a Servicer Termination
Event.


 


In
addition, upon such failure to comply with the reporting requirements set forth in this Agreement, subject to any applicable grace
periods, the Servicer or Special Servicer, as applicable (and any Sub-Servicing Entity that defaults in accordance with clause
(x) above), shall be terminated at the direction of the Depositor.


 


(c)          If
a Servicer Termination Event or Special Servicer Termination Event shall occur then, and in each and every such case, so long
as such Servicer Termination Event or Special Servicer Termination Event shall not have been remedied, either (i) the Trustee
may, or (ii) upon the written direction of Holders of Certificates having at least 25% of the Voting Rights


 






    -166-


     


    

 


(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, as applicable, the Certificate
Administrator shall, as soon as possible, post such written notice thereof on the Certificate Administrator’s Website and
provide the same to the 17g-5 Information Provider who shall post written notice thereof to the 17g-5 Information Provider’s
Website pursuant to Section 8.14(b), and thereafter, give written notice to the Rating Agency, Depositor, the Certificateholders
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 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 the 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 the Rating Agency conditions
set forth in the Rating Agency Confirmation delivered by the Rating Agency with respect to such successor special servicer.


 






    -167-


     


    

 


(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 the 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 the 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 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 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


 






    -168-


     


    

 


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 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


 






    -169-


     


    

 


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 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 Agency 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


 






    -170-


     


    

 


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.


 


(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


 






    -171-


     


    

 


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.]


 


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


 






    -172-


     


    

 


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 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


 






    -173-


     


    

 


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 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


 






    -174-


     


    

 


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 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


 






    -175-


     


    

 


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 Administrator
hereunder, as applicable.


 


8.2.          Certain
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;


 






    -176-


     


    

 


(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 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 Event or Special Servicer Termination
Event, if such an event shall have occurred and is continuing, and otherwise by the Certificateholders 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 duties hereunder
either directly or by or through agents or attorneys selected by it with due care but shall not thereby be relieved of responsibility
for such duties;


 


(vii)       the
Certificate Administrator shall not be liable for any loss on any investment of funds made by it pursuant to the terms of this
Agreement other than as set forth in Section 3.8 (other than investments made with the Certificate Administrator in its
commercial capacity); and


 


(viii)      neither
the Trustee nor the Certificate Administrator shall be required to post any kind of bond or surety in connection 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.


 






    -177-


     


    

 


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 by one or more employees within the same group or division of Wells Fargo Bank, National Association, or where the
groups or divisions responsible for performing the obligations in such capacities have one or more of the same Responsible Officers,
provided in any event, however, the knowledge of employees performing special servicing functions shall not be imputed to employees
performing master servicing functions, and the knowledge of employees performing master servicing functions shall not be imputed
to employees performing special servicing functions.


 


(b)          Following
the Closing Date, neither the Trustee nor the Certificate Administrator shall accept any contribution of assets to the Trust Fund
not specifically contemplated by this Agreement.


 


(c)          All
rights or actions under this Agreement or under any of the Certificates, enforceable by the Trustee or the Certificate 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
from time to time such identifying information and documentation as may be available for such party in order to enable the Trustee
to comply with Applicable Laws.


 


8.3.          Neither
the Trustee nor the Certificate Administrator is Liable for Certificates or the Trust Loan. The recitals contained
herein and in the Certificates (other than the signature and authentication of the Certificate Administrator on the
Certificates) shall not be taken as the statements of the Trustee or the Certificate Administrator and the Trustee and the
Certificate Administrator 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


 






    -178-


     


    

 


except as expressly set forth herein. The Trustee and the Certificate Administrator shall not be liable for
any action or failure of any action by the Depositor, the Servicer or the Special Servicer hereunder. The Trustee and the Certificate
Administrator shall not at any time have any responsibility or liability for or with respect to the legality, ownership, title,
validity or enforceability of any of the Mortgage or Collateral Security Documents or the Whole Loan, or the perfection, sufficiency
and priority of any of the Mortgage or Collateral Security Documents or the maintenance of any such perfection and priority, or
for or with respect to 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 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


 






    -179-


     


    

 


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, penalties, fines, foreclosures, judgments or 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 (including,
without limitation, reasonable fees and disbursements of counsel incurred in any action or proceeding related thereto); 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

individual or any other capacity may become the owner or pledgee of Certificates with the same rights, powers, and privileges

(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


 






    -180-


     


    

 


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.

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

of Co-Trustee or Separate Trustee. (a) At any time or times, for the purpose of meeting any legal requirements of
any jurisdiction in which any part of the Property may at the time be located or in which any action of the Trustee may be
required to be performed or taken, the Trustee, the Depositor or the Holders of Certificates evidencing, in the aggregate, a
majority of the Voting Rights of the outstanding Certificates, by an instrument in writing signed by it or them, may appoint

(b)          The
Trustee shall execute, acknowledge and deliver all such instruments as may be required by the legal requirements of any jurisdiction

(c)          All
provisions of this Agreement which are for the benefit of the Trustee and Certificate Administrator shall extend to and apply

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

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.


 


(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

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

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 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.

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

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


 


8.14.          Access

Retention Consultation Party or any of the respective affiliates, directors, officers, shareholders, members, partners, agents

9.3.         Rights
and Powers of the Directing Holder, the Risk Retention Consultation Party and the Subordinate Note Holders.


 


(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 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), (iii) the Special Servicer shall also consult on a non-binding basis with the Risk Retention Consultation
Party (unless the Risk Retention Consultation Party is a Borrower Related Party) and (iv) the Special Servicer shall also consult
on a non-binding bases with the holders of the Non-Trust A Notes (provided that after the expiration of a period of (10)
Business Days from the delivery to a holder of a Non-Trust A Note by the Special Servicer of written notice of a proposed action,
the Special Servicer shall no longer by obligated to consult with such holder of a Non-Trust A Note). 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, the Risk Retention
Consultation Party or the holders of the Non-Trust A Notes 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; and provided, further that, the Special Servicer shall consult with the holders of the Non-Trust
A Notes in connection with any Major Decision and consider alternative actions recommended by the holders of the Non-Trust A Notes
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 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


 



    -201-


     


    

 


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.


 


(d)          The
Servicer or the Special Servicer as the case may be, shall provide copies of any notice, information and report that it is required
to provide to the Directing Holder pursuant to this Agreement with respect to any Major Decisions, to the holders of the Non-Trust
A Notes within the same time frame it is required to provide to the 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.


 


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.


 


10.          TERMINATION


 


10.1.       Termination.

10.2.       Additional
Termination Requirements. In connection with any termination pursuant to Section 10.1 other than final payment on the
Whole Loan, the Trust Fund shall be terminated in accordance with the following additional requirements, 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:


 


(i)       
   Within 89 days prior to the final Distribution Date, the Certificate Administrator shall designate the first

Fund; and

all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Lower-Tier REMIC

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 Agency Confirmation is obtained

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

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

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

11.5.       Notices
to the Rating Agency. Any notices or documents required to be delivered to the Rating Agency under this Agreement and any
other information regarding the Trust Fund as may be reasonably requested by the Rating Agency from any party hereto to the extent
such party has or can obtain such information without unreasonable effort or expense shall be delivered to the Rating Agency at

respect to the Rating Agency Inquiry conducted or submitted on the Rating Agency Q&A Forum and Document Request Tool shall

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


 



    -212-


     


    

 


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 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


 



    -213-


     


    

 


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.


 


(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


 



    -214-


     


    

 


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.


 


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


 



    -215-


     


    

 


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 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).


 






    -216-


     


    

 


(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 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


 



    -217-


     


    

 


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.


 


(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


 



    -218-


     


    

 


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.


 


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 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;


 






    -219-


     


    

 


(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 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 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


 



    -221-


     


    

 


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.

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
2018-OSS, Commercial Mortgage Pass-Through Certificates, Series 2018-OSS, 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


 



    -222-


     


    

 


servicer,
as applicable, shall provide) to any Senior Companion Loan Depositor as to which the related 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, (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 related
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

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

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 affected, to accurately and timely report the event under Items 1.01 and 6.02 of Form 8-K pursuant

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
Items 1.01 and 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).

that is a Sub-Servicer set forth on Exhibit W with which it has entered into a servicing relationship with respect to the

to any other Servicing Function Participant of such party (other than any party to this Agreement), shall cause such Servicing
Function Participant to furnish) a registered public accounting firm (which may also render other services to the Servicer, the
Special Servicer, the Certificate Administrator, the Trustee or the applicable Servicing Function Participant, as the case may

(who shall post it to the Certificate Administrator’s Website pursuant to Section 8.14(b)), the Depositor, the Companion
Loan Holders (or, in the case of any Senior Companion Loan that is part of a Senior Companion Loan Securitization Trust, the applicable
Senior Companion Loan Depositor and Senior Companion Loan Exchange Act Reporting Party) and the 17g-5 Information Provider (who
shall post it to the 17g-5 Information Provider’s Website pursuant to Section 8.14(b)), to the effect that (i) it
has obtained a representation regarding certain matters from the management of such Reporting Servicer, which includes an assessment
from such Reporting Servicer of its compliance with the Applicable Servicing Criteria and (ii) on the basis of an examination
conducted by such firm in accordance with standards for attestation engagements issued or adopted by the Public Company Accounting
Oversight Board, it is expressing an opinion as to whether such Reporting Servicer’s assessment of compliance with the Servicing
Criteria was fairly stated in all material respects, or it cannot express an overall opinion regarding such party’s assessment
of compliance with the Applicable Servicing Criteria. In the event that an overall opinion cannot be expressed, such registered
public accounting firm shall state in such report why it was unable to express such an opinion. Each accountant’s attestation
report required hereunder shall be made in accordance with Rules 1-02(a)(3) and 2-02(g) of Regulation S-X under the Act and the
Exchange Act. Such report must be available for general use and not contain restricted use language. Copies of all statements
delivered pursuant to this Section 13.9 shall be made available to any Privileged Person by the Certificate Administrator
posting such statement on the Certificate Administrator’s Website pursuant to Section 8.14(b).


 


For
so long as any Senior Companion Loan Securitization Trust is subject to the reporting requirements of the Exchange Act, promptly
after receipt of such report from the Servicer, the Special Servicer, the Certificate Administrator, the Trustee or any Servicing
Function Participant, the Depositor and each Senior Companion Loan Depositor may review the report and, if applicable, consult
with the Servicer, the Special Servicer, the Certificate Administrator or the Trustee as to the nature of any defaults by the
Servicer, the Special Servicer, the Certificate Administrator, the Trustee or any Servicing Function Participant with which it
has entered into a servicing relationship with respect to the Trust Loan or any Companion Loan, as the case may be, in the fulfillment
of any of the Servicer’s, the Special Servicer’s, the Certificate Administrator’s, the Trustee’s or the

that the Servicer is in receipt of the updated financial statements of such “significant obligor” for any calendar
quarter (other than the fourth calendar quarter of any calendar year) from the Mortgagor or Special Servicer, beginning with the
first calendar quarter following receipt of such notice from such Senior Companion Loan Depositor, or the updated financial statements
of such “significant obligor” for any calendar year, beginning for the calendar year following such notice from such
Senior Companion Loan Depositor, as applicable, the Servicer shall deliver to such Senior Companion Loan Depositor, on or prior
to the day that occurs two (2) Business Days prior to the related “significant obligor” NOI Quarterly Filing Deadline
or seven (7) Business Days prior to the related Significant Obligor NOI Yearly Filing Deadline, as applicable, (A) if such financial

13.11.     Sarbanes-Oxley
Backup Certification. For so long as any Senior Companion Loan Securitization Trust is subject to the reporting requirements
of the Exchange Act, the Certificate Administrator, the Servicer, the Special Servicer and the Trustee shall provide (and with
respect to any other Servicing Function Participant of such party, shall cause such Servicing Function Participant to provide)
to the Person who signs the Sarbanes-Oxley Certification with respect to such Senior Companion Loan Securitization Trust (the
“Certifying Person”) no later than March 1 of the year following the year to which the Form 10-K of such Senior
Companion Loan Securitization Trust relates or, if March 1 is not a Business Day, on the immediately following Business Day, a
certification in the form attached to this Agreement as Exhibit X-1, Exhibit X-2, Exhibit X-3 or Exhibit
X-4, as applicable, on which the Certifying Person, the entity for which the Certifying Person acts as an officer, and such
entity’s officers, directors and Affiliates (collectively with the Certifying Person, “Certification Parties”)
can reasonably rely. 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 the Certifying Person pursuant to this Section 13.11 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.


 


13.12.     Indemnification.

Companion
Loan Depositor and any employee, director or officer of the Depositor or any Senior Companion Loan 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 such indemnified party arising out of (i) an actual breach by the Servicer, the Special Servicer, the
Certificate Administrator or the Trustee, as the case may be, of its obligations under this Article 12, (ii) negligence, bad faith
or willful misconduct on the part of the Servicer, the Special Servicer, the Certificate Administrator or the Trustee, as applicable,
in the performance of such obligations or (iii) delivery of any Deficient Exchange Act Deliverable regarding such party and delivered
by or on behalf of such party.


 


The
Servicer, the Special Servicer, the Certificate Administrator and the Trustee shall cause each Servicing Function Participant
of such party that is not a Sub-Servicer set forth on Exhibit W (and with respect to any Servicing Function Participant
of such party that is a Sub-Servicer set forth on Exhibit W, shall use commercially reasonable efforts to cause such Servicing
Function Participant) to indemnify and hold harmless the Depositor, each Senior Companion Loan Depositor and any employee, director
or officer of the Depositor or any Senior Companion Loan Depositor from and against any and all claims, losses, damages, penalties,
fines, forfeitures, legal fees and expenses and related costs, judgments and any other costs, fees and expenses incurred by such
indemnified party arising out of (i) a breach of its obligations to provide any of the annual compliance statements or annual

If
the indemnification provided for in, or contemplated by, either of the prior two paragraphs is unavailable or insufficient to
hold harmless the Depositor, any Senior Companion Loan Depositor or any employee, director or officer of the Depositor or any
Senior Companion Loan Depositor, then the Servicer, the Special Servicer, the Certificate Administrator, the Trustee, the Additional
Servicer or other Servicing Function Participant (the “Performing Party”) shall contribute to the amount paid
or payable to the indemnified party as a result of the losses, claims, damages or liabilities of the indemnified party in such
proportion as is appropriate to reflect the relative fault of the indemnified party on the one hand and the Performing Party on
the other in connection with a breach of the Performing Party’s obligations pursuant to this Article 13 (or breach
of its obligations under the applicable sub-servicing agreement to provide any of the annual compliance statements or annual servicing
criteria compliance reports or attestation reports) or the Performing party’s negligence, bad faith or willful misconduct
in connection therewith.


 


The
Servicer, the Special Servicer, the Certificate Administrator and the Trustee shall cause each Servicing Function Participant
of such party that is not a Sub-Servicer set forth on Exhibit W (and with respect to any Servicing Function Participant
of such party that is a Sub-Servicer set forth on Exhibit W, shall use commercially reasonable efforts to cause such Servicing
Function Participant) to agree to the foregoing indemnification and contribution obligations. This Section 13.11 shall
survive the termination of this Agreement or the earlier resignation or removal of the Servicer, the Special Servicer or the Certificate
Administrator.

13.14.     Termination
of the Certificate Administrator. Notwithstanding anything to the contrary contained in this Agreement, the Depositor or any

until a successor Certificate Administrator shall have accepted the appointment.


 


13.15.     Termination
of Sub-Servicing Agreements. 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 Certificate Administrator and the Trustee, as applicable, shall (i) cause each
Sub-Servicing Agreement to which it is a party to entitle the Depositor or any Senior Companion Loan Depositor to terminate such
agreement (without compensation, termination fee or the consent of any other Person) at any time following any failure of the
applicable Sub-Servicer to any deliver any Exchange Act reporting items that such Sub-Servicer is required to deliver under Regulation
AB or as otherwise contemplated by this Article 13 and (ii) promptly notify the Depositor and any Senior Companion Loan
Depositor following any failure of the applicable Sub-Servicer to deliver any Exchange Act reporting items that such Sub-Servicer

Trustee and Certificate Administrator in cooperating with such Senior Companion Loan Depositor or Senior Companion Loan Exchange
Act Reporting Party of such Senior Companion Loan Securitization Trust (above and beyond their expressed duties hereunder) shall
be the responsibility of such Senior Companion Loan Depositor or Senior Companion Loan Securitization Trust. The parties hereto

be required to deliver such items; provided that no such confirmation will be required in connection with any delivery
of the items contemplated by Section 13.7, Section 13.8 and Section 13.9 of this Agreement. Such confirmation

Trust is subject to the reporting requirements of the Exchange Act and the appropriate party hereto receives such written statement.

(b)          Each

Senior Companion Loan Depositor) for inclusion in the disclosure materials relating to any securitization of a Companion Loan.


 


(c)          The
Servicer, the Special Servicer, the Certificate Administrator and the Trustee, upon reasonable prior written request given in
accordance with the terms of Section 13.16(a) above, shall each timely provide (to the extent the reasonable cost thereof

agreement(s) with respect to the updated description referred in Section 13.16(b) with respect to such party, substantially
identical to those, if any, delivered by the Servicer, the Special Servicer, the Trustee or the Certificate

Administrator,
as the case may be, or their respective counsel, in connection with the information concerning such party in the Offering Circular
and/or any other disclosure materials relating to this Trust (updated as deemed appropriate by the Servicer, the Special Servicer,
the Trustee or the Certificate Administrator, or their respective legal counsel, as the case may be, and sufficient to comply
with Regulation AB). None of the Servicer, the Special Servicer, the Trustee or the Certificate Administrator shall be obligated

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 March 2018 (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.


 






    Exhibit A-1-4


     


    

 


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 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,


 






    Exhibit A-1-5


     


    

 


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, (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.

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.


 






    Exhibit A-2-5


     


    

 


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 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,


 






    Exhibit A-2-6


     


    

 


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, (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.

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 March 2018 (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 C 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.


 






    Exhibit A-3-5


     


    

 


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 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,


 






    Exhibit A-3-6


     


    

 


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

This

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, Class

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 February
27, 2018 (the “Trust and Servicing Agreement”), by and among Natixis Commercial Mortgage Securities LLC, as

    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 March 2018 (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.


 






    Exhibit A-4-5


     


    

 


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 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,


 






    Exhibit A-4-6


     


    

 


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, (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.

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 X 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 B, Class
C, Class D, Class V1-AB, Class V1-C, Class V1-D, Class V2 and Class R Certificates (collectively with the Class X 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 February
27, 2018 (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,

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 March 2018 (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 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.


 


During
each Certificate Interest Accrual Period (as defined below), interest on the Class X 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
and including the fifth day of the calendar month immediately preceding the calendar month in which such Distribution Date occurs
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
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-6-5


     


    

 


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-6-6


     


    

 


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.


 


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, (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.

THE TRUSTEE, THE INITIAL PURCHASERS, THE LOAN SELLERS, THE CERTIFICATE ADMINISTRATOR OR ANY OF THEIR RESPECTIVE AFFILIATES (OTHER
THAN THE BORROWER AS SET FORTH IN THE OFFERING CIRCULAR). NEITHER THIS CERTIFICATE NOR THE UNDERLYING LOAN ARE INSURED OR GUARANTEED
BY ANY GOVERNMENTAL AGENCY OR INSTRUMENTALITY.


 


THIS

TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G(a)(2) AND 860D OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED. EACH TRANSFEREE

TO DISQUALIFIED ORGANIZATIONS, NON-U.S. PERSONS OR AGENTS OF EITHER, AS SET FORTH IN SECTION 5.2 OF THE TRUST AND SERVICING AGREEMENT,
AND SHALL BE REQUIRED TO FURNISH AN AFFIDAVIT TO THE TRANSFEROR AND THE CERTIFICATE ADMINISTRATOR TO THE EFFECT THAT, AMONG OTHER
THINGS, (A) IT IS NOT A DISQUALIFIED ORGANIZATION, AS SUCH TERM IS DEFINED IN CODE SECTION 860E(e)(5), OR AN AGENT (INCLUDING
A BROKER, NOMINEE OR OTHER MIDDLEMAN) FOR SUCH DISQUALIFIED ORGANIZATION AND IS OTHERWISE A PERMITTED TRANSFEREE, (B) IT HAS HISTORICALLY
PAID ITS DEBTS AS THEY HAVE COME DUE AND INTENDS TO PAY ITS DEBTS AS THEY COME DUE IN THE FUTURE, (C) IT UNDERSTANDS THAT IT MAY
INCUR TAX LIABILITIES WITH RESPECT TO THIS CERTIFICATE IN EXCESS OF CASH FLOWS GENERATED HEREBY, (D) IT INTENDS TO PAY ANY TAXES
ASSOCIATED WITH HOLDING THIS CERTIFICATE AS THEY BECOME DUE, (E) IT WILL NOT CAUSE INCOME WITH RESPECT TO THIS CERTIFICATE TO
BE ATTRIBUTABLE TO A FOREIGN PERMANENT ESTABLISHMENT OR FIXED BASE, WITHIN THE MEANING OF AN APPLICABLE INCOME TAX TREATY, OF
SUCH PERSON OR ANY OTHER U.S. PERSON AND (F) IT WILL NOT TRANSFER THIS CERTIFICATE TO ANY PERSON OR ENTITY THAT DOES NOT PROVIDE
A SIMILAR AFFIDAVIT. ANY PURPORTED TRANSFER TO A DISQUALIFIED ORGANIZATION OR OTHER PERSON THAT IS NOT A PERMITTED TRANSFEREE
OR OTHERWISE IN VIOLATION OF THESE RESTRICTIONS SHALL BE ABSOLUTELY NULL AND VOID AND SHALL VEST NO RIGHTS IN ANY PURPORTED TRANSFEREE.
BECAUSE THIS CERTIFICATE REPRESENTS MULTIPLE “NON-ECONOMIC RESIDUAL INTERESTS”, AS DEFINED IN TREASURY REGULATIONS

AS SPECIFIED IN TREASURY REGULATIONS.


 


THE

This
certifies that [______] 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 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, Class B, Class C, Class D, Class V1-AB, Class V1-C, Class V1-D 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 February
27, 2018 (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-6-4


     


    

 


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-6-5


     


    

 





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-6-6


     


    

 





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, (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.

V1-D,
Class V2 and Class R (collectively with the Class V1-C 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 February
27, 2018 (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 March 2018 (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 V1-C 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-8-5


    


    

 


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-8-6


    


    

 


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

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

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 February
27, 2018 (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,

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 March 2018 (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

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 V1-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

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.


 






    Exhibit A-9-5


    


    

 


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-9-6


    


    

 


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.


 


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, (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.

V1-C,
Class V1-D 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 February
27, 2018 (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 March 2018 (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-10-5


    


    

 


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-10-6


    


    

 


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, (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.

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

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.

3.          That

Series 2018-OSS, Class R (the “Residual Certificate”) and, further, that the Purchaser is a Permitted Transferee
(as defined in Article I of the Trust and Servicing Agreement, dated as of February 27, 2018 (the “Trust and Servicing

or is acquiring the Residual Certificate for the account of, or as agent (including as a broker, nominee, or other middleman)

4.          That
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 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
generated by the Residual Certificate.


 


6.          That
the Purchaser will not transfer the Residual Certificate to any person or entity from which the Purchaser has not received an
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.

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.

                                         as it retains its interest in the RR Interest, it will remain a Majority-Owned Affiliate.

Ladies
and Gentlemen:


 


This
letter is delivered to you in connection with the transfer by _________________ (the “Transferor”) to _________________
(the “Transferee”) of the Excess Servicing Fee Right established under the Trust and Servicing Agreement, dated
as of February 27, 2018 (the “Trust and Servicing Agreement”) and executed in connection with the NCMS 2018-OSS
securitization transaction. All capitalized terms used but not otherwise defined herein shall have the respective meanings set
forth in the Trust and Servicing Agreement. The Transferee hereby certifies, represents and warrants to you, as the Depositor
and the Master Servicer, that:


 


1.          The
Transferee is acquiring the right to receive Excess Servicing Fees with respect to the Whole Loan as to which __________________
is the applicable Master Servicer (the “Excess Servicing Fee Right”) for its own account for investment and
not with a view to or for sale or transfer in connection with any distribution thereof, in whole or in part, in any manner which
would violate the Securities Act of 1933, as amended (the “Securities Act”), or any applicable state securities
laws.


 


2.          The
Transferee understands that (a) the Excess Servicing Fee Right has not been and will not be registered under the Securities Act
or registered or qualified under any applicable state securities laws, (b) none of the Depositor, the Trustee, Certificate Administrator
or the Certificate Registrar is obligated so to register or qualify the Excess Servicing Fee Right, and (c) the Excess Servicing
Fee Right may not be resold or transferred unless it is (i) registered pursuant to the Securities Act and registered or qualified
pursuant to any applicable state securities laws or (ii) sold or transferred in transactions which are exempt from such registration
and qualification and (A) the Depositor has received a certificate from the prospective transferor substantially in the form attached
as Exhibit P-1 to the Trust and Servicing Agreement, and (B) each of the Master Servicer and the Depositor have received a certificate

transferee substantially in the form attached as Exhibit P-2 to the Trust and Servicing Agreement.


 


3.          The
Transferee understands that it may not sell or otherwise transfer the Excess Servicing Fee Right or any interest therein except
in compliance with the provisions of Section 3.17 of the Trust and Servicing Agreement, which provisions it has carefully reviewed.


 


4.          Neither
the Transferee nor anyone acting on its behalf has (a) offered, pledged, sold, disposed of or otherwise transferred the Excess
Servicing Fee Right, any interest in the Excess Servicing Fee Right or any other similar security to any person in any manner,
(b) solicited any offer to buy or accept a pledge, disposition or other transfer of the Excess Servicing Fee Right, any interest

any person in any manner, (d) made any general solicitation with respect to the Excess Servicing Fee Right, any interest in the
Excess Servicing Fee Right or any other similar security by means of general advertising or in any other manner, or (e) taken
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 (including in the case of any of the acts described in clauses (a) through (e) above) would constitute a distribution
of the Excess Servicing Fee Right under the Securities Act, would render the disposition of the Excess Servicing Fee Right a violation
of Section 5 of the Securities Act or any state securities law or would require registration or qualification of the Excess Servicing
Fee Right pursuant thereto. The Transferee will not act, nor has it authorized or will it authorize any person to act, in any
manner set forth in the foregoing sentence with respect to the Excess Servicing Fee Right, any interest in the Excess Servicing
Fee Right or any other similar security.


 


5.          The
Transferee has been furnished with all information regarding (a) the Depositor, (b) the Excess Servicing Fee Right and any payments
thereon, (c) the Trust and Servicing Agreement and the Trust Fund created pursuant thereto, (d) the nature, performance and servicing

Act or an entity in which all of the equity owners are “accredited investors” as defined in any of paragraphs (1),
(2), (3) and (7) of Rule 501(a) under the Securities Act. The Transferee has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of an investment in the Excess Servicing Fee Right; the Transferee
has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision; and the
Transferee is able to bear the economic risks of such investment and can afford a complete loss of such investment.


 


7.          The
Transferee agrees (i) to keep all information relating to the Trust, the Trust Fund and the parties to the Trust and Servicing
Agreement, and made available to it, confidential, (ii) not to use or disclose such information in any manner which could result
in a violation of any provision of the Securities Act or would require registration of the Excess Servicing Fee Right or any Certificate
pursuant to the Securities Act, and (iii) not to disclose


 






    Exhibit M-7-2


     


    

 


such information, and to cause its officers, directors, partners, employees,
agents or representatives not to disclose such information, in any manner whatsoever, in whole or in part, to any other Person
other than such holder’s auditors, legal counsel and regulators, except to the extent such disclosure is required by law,
court order or other legal requirement or to the extent such information is of public knowledge at the time of disclosure by such
holder or has become generally available to the public other than as a result of disclosure by such holder; provided, however,
that such holder may provide all or any part of such information to any other Person who is contemplating an acquisition of the
Excess Servicing Fee Right if, and only if, such Person (x) confirms in writing such prospective acquisition and (y) agrees in
writing to keep such information confidential, not to use or disclose such information in any manner which could result in a violation
of any provision of the Securities Act or would require registration of the Excess Servicing Fee Right or any Certificates pursuant
to the Securities Act and not to disclose such information, and to cause its officers, directors, partners, employees, agents
or representatives not to disclose such information, in any manner whatsoever, in whole or in part, to any other Person other
than such Persons’ auditors, legal counsel and regulators.


 


8.          The
Transferee acknowledges that the holder of the Excess Servicing Fee Right shall not have any rights under the Trust and Servicing
Agreement except as set forth in Section 3.12(a) of the Trust and Servicing Agreement, and that the Excess Servicing Fee Rate
may be reduced to the extent provided in the Trust and Servicing Agreement.
