(without regard to the time periods stated therein), then, until such Appraisal is obtained and solely for purposes of determining
the amounts of P&I Advances, the Appraisal Reduction Amount for or allocable to the related Serviced Mortgage Loan will equal
25% of the Stated Principal Balance of such related Serviced Mortgage Loan; provided that, upon receipt of an Appraisal,
however, the Appraisal Reduction Amount for such Serviced Mortgage Loan (or Serviced Loan Combination) will be recalculated in
accordance with this definition without regard to this sentence. With respect to each Serviced Loan as to which an Appraisal Reduction
Event has occurred (unless the Serviced Loan has become a Corrected Loan (if a Servicing Transfer Event had occurred with respect
to the related Serviced Loan) and has remained current for three consecutive Monthly Payments, and with respect to which no other
Appraisal Reduction Event has occurred during the preceding three months), the Special Servicer shall, within 30 days of each
anniversary of such Appraisal Reduction Event, order an Appraisal (which may be an update of the prior Appraisal) (the cost of
which will be covered by, and reimbursable as, a Property Advance by the Master Servicer or as an expense of the Trust Fund and
paid by the Master Servicer out of the Collection Account if such Property Advance would be a Nonrecoverable Advance), provided,
however, no new or updated Appraisal will be required if the Serviced Loan or REO Property is under contract to be sold
within 90 days of such Appraisal Reduction Event or anniversary thereof and the Special Servicer reasonably believes such
sale is likely to close. Based upon such Appraisal or letter updates thereto, the Special Servicer shall determine and report to
the Master Servicer and the Certificate Administrator the Appraisal Reduction Amount, if any, with respect to such Serviced Mortgage
Loan (or Serviced Loan Combination), and each of those parties shall be entitled to rely conclusively on such determination by
the Special Servicer. The Special Servicer shall deliver a copy of any such Appraisal to the Master Servicer and the Certificate
Administrator, which shall be in electronic format. Each Appraisal Reduction Amount shall also be adjusted with respect to the
next Distribution Date to take into account any subsequent Appraisal and annual letter updates, as of the date of each such subsequent
Appraisal or letter update.


 


Upon payment in full
or liquidation of any Serviced Loan for which an Appraisal Reduction Amount has been determined, such Appraisal Reduction Amount
will be eliminated. In addition, with respect to any Serviced Loan, as to which an Appraisal Reduction Event has occurred, such
Serviced Loan shall no longer be subject to the Appraisal Reduction Amount if


 






    	-11-

Loan (if a Servicing Transfer Event had occurred with respect to the related Serviced Loan) and such Serviced Loan becomes and

with respect to such Serviced Loan.


 


Appraisal Reduction Amounts

Serviced Pari Passu Companion Loan(s) on a pro rata and pari passu basis in accordance with the respective outstanding principal
balances of such Serviced Mortgage Loan and the related Serviced Pari Passu Companion Loan.


 


Notwithstanding the foregoing,

Servicing Agreement by the related Outside Special Servicer or related Outside Servicer, as applicable, and that is allocable to
such Outside Serviced Mortgage Loan pursuant to such Outside Servicing Agreement and the related Co-Lender Agreement. The parties
hereto shall be entitled to rely on such calculations as reported to them by the related Outside Servicer. By their acceptance
of their Certificates, the Certificateholders shall be deemed to have acknowledged that the applicable Outside Servicing Agreement
and the related Co-Lender Agreement, taken together, provide that any such “appraisal reduction amount” will be calculated
under the applicable Outside Servicing Agreement by the applicable party thereto.

Event”: With respect to any Serviced Loan, the earliest of (i) the date on which such Serviced Loan becomes a Modified

(B) if the related Mortgagor has delivered to the Master Servicer (who shall promptly deliver a copy thereof to the Special
Servicer) or the Special Servicer (who shall promptly deliver a copy thereof to the Master Servicer) a refinancing commitment acceptable
to the Special Servicer prior to the date 60 days after the Balloon Payment was due, the date occurring 120 days after
the date on which the Balloon Payment was due (or such shorter period beyond the date on which that Balloon Payment was due during
which the refinancing is scheduled to occur), (iv) the date on which the related Mortgaged Property has become an REO Property,
(v) a receiver or similar official is appointed and continues for 60 days in such capacity in respect of the related
Mortgaged Property, (vi) 60 days after the related Mortgagor is subject to a bankruptcy, insolvency or similar proceedings,
which, in the case of an involuntary bankruptcy, insolvency or similar proceeding, is not dismissed within those 60 days,
or (vii) the date on which such Serviced Loan remains outstanding five (5) years following any extension of its maturity date
pursuant to Section 3.24 of this Agreement. If an Appraisal Reduction Event occurs with respect to any Serviced Mortgage
Loan that is part of a Serviced Loan Combination, then an Appraisal Reduction Event shall be deemed to have occurred with respect
to the related Serviced Companion Loan(s). If an Appraisal Reduction Event occurs with respect to any Serviced Companion Loan that
is part of a Serviced Loan Combination, then an Appraisal Reduction Event shall be deemed to have occurred with respect to the
related Serviced Mortgage Loan and any other Serviced

Companion Loan(s) included as part of that Serviced Loan Combination. No

(other than the Class A-1, Class A-2, Class A-3, Class A-4 and Class A-AB Certificates) has been

Master Servicer or the Special Servicer (and, in the case of the Special Servicer, with the consent of the related Directing Holder
(unless, if the Controlling Class Representative is the related Directing Holder, a Control Termination Event has occurred and
is continuing)) has determined that (i) a default (other than an Acceptable Insurance Default) under the Serviced Loan is
reasonably foreseeable, (ii) such default will materially impair the value of the related Mortgaged Property as security
for such Serviced Loan or otherwise materially adversely affects the interests of Certificateholders in the Serviced Mortgage
Loan (or, in the case of a Serviced Loan Combination, the interests of the Certificateholders or the related Serviced Companion
Loan Holder(s) in such Serviced Loan Combination), and (iii) the default is likely to continue unremedied for the applicable

    	-120- 



     


    

 


provided,
however, that a Serviced Loan will cease to be a Specially Serviced Loan, when a Liquidation Event has occurred with respect
to such Serviced Loan or any related REO Property or, so long as at such time no circumstance identified in clauses (a) through
(g) above exists that would cause the Serviced Loan to continue to be characterized as a Specially Serviced Loan, when:


 


(w)           with
respect to the circumstances described in clause (a) of this definition, the related Mortgagor has made three consecutive
full and timely Monthly Payments under the terms of such Serviced Loan (as such terms may be changed or modified in connection
with a bankruptcy or similar proceeding involving the related Mortgagor or by reason of a modification, extension, waiver or amendment
granted or agreed to by the Master Servicer or the Special Servicer pursuant to Section 3.24 of this Agreement);


 


(x)            with
respect to the circumstances described in clauses (c), (d), (e) and (f) of this definition, such circumstances cease to exist
in the good faith, reasonable judgment of the Special Servicer, but, with respect to any bankruptcy or insolvency proceedings
described in clauses (d), (e) and (f), no later than the entry of an order or decree dismissing such proceeding;


 


(y)            with
respect to the circumstances described in clause (b) of this definition, such default is cured as determined by the Special
Servicer in its reasonable, good faith judgment; and


 


(z)            with
respect to the circumstances described in clause (g) of this definition, such proceedings are terminated.


 


The
Special Servicer may conclusively rely on the Master Servicer’s determination and the Master Servicer may conclusively rely
on the Special Servicer’s determination as to whether a Servicing Transfer Event has occurred giving rise to a Serviced
Loan’s becoming a Specially Serviced Loan. If any Serviced Mortgage Loan that is part of a Serviced Loan Combination becomes
a Specially Serviced Loan, then the related Serviced Companion Loan shall also become a Specially Serviced Loan. If the Serviced
Companion Loan that is included in a Serviced Loan Combination becomes a Specially Serviced Loan, then the related Serviced Mortgage

of a reduction of principal by a bankruptcy court or as a result of a modification reducing the principal balance of such Mortgage

principal of such Serviced Companion Loan and (ii) any adjustment to the principal balance of such Serviced Companion Loan

Loan that has been paid in full or a Specially Serviced Loan with respect to which the Special Servicer has made a Final Recovery
Determination (or, in the case of an Outside Serviced Mortgage Loan, with respect to which the Outside Special Servicer has made

case such applications shall be determined by the Master Servicer) in accordance with the Servicing Standard.


 


(g)            All
net present value calculations and determinations made hereunder with respect to the Mortgage Loans, the Serviced Companion Loans
or a Mortgaged Property or REO Property (including for purposes of the definition of “Servicing Standard”, and including,
if and when applicable, with respect to an Outside Serviced Mortgage Loan or the related Mortgaged Property or any related REO

(h)            For
purposes of calculating Pass-Through Rates and distributions on, and allocations of Realized Losses to, the Certificates, as well
as for purposes of calculating the Servicing Fee, the Trustee/Certificate Administrator Fee, the Operating Advisor Fee and the
Asset Representations Reviewer Ongoing Fee payable each month, each REO Property (including any REO Property with respect to an
Outside Serviced Mortgage Loan held pursuant to an Outside Servicing Agreement) will be treated as if the related Mortgage Loan
and any related Companion Loan(s) had remained outstanding and the related Loan Documents continued in full force and effect;
and all references to “Mortgage Loan,” “Mortgage Loans” or “Mortgage Pool” in this Agreement,
when used in that context, will be deemed to also be references to or to also include, as the case may be, any REO Mortgage Loan,
and all references to “Companion Loan” or “Companion Loans” in this Agreement, when used in that context,
will be deemed to also be references to or to also include, as the case may be, any REO Companion Loan. Each REO Loan will generally
be deemed to have the same characteristics as its actual predecessor Mortgage Loan or Companion Loan, as applicable, including
the same fixed Mortgage Rate (and, accordingly, the same Net Mortgage Rate) and the same unpaid principal balance and Stated Principal
Balance. Amounts due on the predecessor Mortgage Loan or Companion Loan, as applicable, including any portion of those amounts
payable or reimbursable to the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Certificate Administrator or the Trustee, as applicable, will continue to be “due” in respect of the REO Loan;
and amounts received in respect of the related REO Property, net of payments to be made, or reimbursements to the Master Servicer
or Special Servicer for payments previously advanced, in connection with the operation and management of that property, generally
will be applied by the Master Servicer as if received on the predecessor Mortgage Loan or Companion Loan, as applicable.

    	-137- 



     


    

 


subordinate Class of Regular Certificates, in the event that the Class A-1, Class A-2,
Class A-3, Class A-4 and Class A-AB Certificates are the only Classes of Principal Balance Certificates outstanding,
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB and Class X-A Certificates together will
be treated as the most subordinate Class of Regular Certificates. For purposes of this Agreement, each Class of Certificates (other
than the Class S and Class R Certificates) shall be deemed to be outstanding only to the extent its respective Certificate
Balance or Notional Amount has not been reduced to zero. For purposes of this Agreement, the Class R Certificates shall be
deemed to be outstanding so long as the Trust REMICs have not been terminated pursuant to Section 9.01 of this Agreement.


 


(b)            For
purposes of this Agreement, except as otherwise expressly provided or unless the context otherwise requires:


 


(i)             the
terms defined in this Agreement include the plural as well as the singular, and the use of any gender herein shall be deemed to
include the other gender;

without reference to a document are to designated Articles, Sections, Subsections, Paragraphs and other subdivisions of this Agreement;


 


(iii)           a
reference to a Subsection without further reference to a Section is a reference to such Subsection as contained in the same Section
in which the reference appears, and this rule shall also apply to Paragraphs and other subdivisions;


 


(iv)           the
words “herein”, “hereof”, “hereunder”, “hereto”, “hereby” and other
words of similar import refer to this Agreement as a whole and not to any particular provision; and


 


(v)            the

the definition of “Mortgage File” (to the extent that recordation of such item would have otherwise been required)
will be recorded in the name of the trustee for that securitization. None of the Certificate Administrator, the Trustee, the Custodian,
the Master Servicer or the Special Servicer shall be liable for any failure by any Mortgage Loan Seller or the Depositor to comply

If a letter of credit referred to in the previous sentence is not in a form that would allow the Master Servicer to draw on such
letter of credit on behalf of the Trustee for the benefit of Certificateholders and, if applicable, the related Serviced Companion
Loan Holder in accordance with the applicable terms thereof and/or of the related Loan Documents, the applicable Mortgage Loan
Seller shall deliver the appropriate assignment or amendment documents (or copies of such assignment or amendment documents if
the related Mortgage Loan Seller has submitted the originals to the related issuer of such letter of credit for processing) to
the Master Servicer within 90 days of the Closing Date; provided that with respect to a Servicing Shift Mortgage Loan, no
such assignments shall be made until the earlier of (i) the related Servicing Shift Date, in which case such assignments shall
be made in accordance with the related Servicing Shift Mortgage Loan Pooling and Servicing Agreement, and (ii) the earlier of
(A) 180 days after the Closing Date and (B) such time as any such letter of credit is required to be drawn upon by the Master

and Servicing Agreement. The applicable Mortgage Loan Seller shall pay any costs of assignment or amendment of such letter(s)
of credit required in order for the Master Servicer to draw on such letter(s) of credit on behalf of the Trustee for the benefit
of Certificateholders and, if applicable, the related Serviced Companion Loan Holder, and shall cooperate with the reasonable
requests of the Master Servicer or the Special Servicer, as applicable, in connection with effectuating a draw under any such
letter of credit prior to the date such letter of credit is assigned or amended in order that it may be drawn by the Master Servicer
on behalf of the Trustee for the benefit of Certificateholders and, if applicable, the related Serviced Companion Loan Holder.


 


With
respect to any Serviced Mortgage Loan secured by a Mortgaged Property that is subject to a franchise agreement with a related
comfort letter in favor of the related Mortgage Loan Seller that requires notice to or request of the related franchisor to transfer
or assign any such related comfort letter to the Trustee for the benefit of the Certificateholders (and, if applicable, the related
Serviced Companion Loan Holder(s)) or have a new comfort letter (or any such new document or acknowledgement as may be contemplated
under the existing comfort letter) issued in the name of the Trustee for the benefit of the Certificateholders (and, if applicable,
the related Serviced Companion Loan Holder(s)), the related Mortgage Loan Seller or its designee shall, within 45 days of the
Closing Date (or any shorter period if required by the applicable comfort letter), provide any such required notice or make any
such required request to the related franchisor for the transfer or assignment of such comfort letter or issuance of a new comfort

such notice or request to the Custodian (who shall include such document in the related Mortgage File) and the Master Servicer,
and the Master Servicer shall use reasonable efforts in accordance with the Servicing Standard to acquire such replacement comfort

letter), and the Master Servicer shall, as soon as reasonably practicable following receipt thereof, deliver the original of such
replacement comfort letter, new document or acknowledgement, as applicable, to the Custodian for inclusion in the Mortgage File.


 


After
the Depositor’s transfer of the Mortgage Loans to the Trustee pursuant to this Section 2.01(b), the Depositor shall
not take any action inconsistent with the Trust’s ownership of the Mortgage Loans.


 


(c)            The
Depositor hereby represents and warrants that each Mortgage Loan Seller has covenanted in the applicable Mortgage Loan Purchase
Agreement that it shall record and file, or cause a third party on its behalf to record and file, at the related Mortgage Loan
Seller’s expense, in the appropriate public recording office for real property records or UCC financing statements, as appropriate,
each related assignment of Mortgage and assignment of Assignment of Leases referred to in clause (4) of the definition of “Mortgage
File” and each related UCC-3 assignment referred to in clause (15) of the definition of “Mortgage File”, in
each case in favor of the Trustee. This subsection (c) shall not apply to any Outside Serviced Mortgage Loan
because the documents referred to herein have been assigned to the related Outside Trustee.


 


Notwithstanding
the foregoing, with respect to a Servicing Shift Mortgage Loan: (A) the instruments of assignment referred to in clauses (4),
(5) and (14) in the definition of “Mortgage File” may be in blank and need not be recorded pursuant to this Agreement
(to the extent recordation would have otherwise been required) until the earliest of (i) the related Servicing Shift Date, in
which case such instruments shall be completed and, if applicable, recorded in accordance with the related Servicing Shift Mortgage
Loan Pooling and Servicing Agreement, and the related Mortgage Loan Seller shall deliver or cause the delivery of photocopies
of any such instruments of assignment so completed and recorded to the Custodian, (ii) such Servicing Shift Mortgage Loan becomes
a Specially Serviced Mortgage Loan prior to the related Servicing Shift Date, in which case such assignments shall be completed

the Closing Date, in which case assignments shall be completed and, if applicable, recordations shall be effected in accordance
with this Agreement upon such occurrence; and (B) following the related Servicing Shift Date and upon the transfer of servicing
of the related Servicing Shift Mortgage Loan to the related Outside Servicing Agreement in accordance with the related Co-Lender
Agreement, the Custodian shall deliver the originals of all documents constituting the related Mortgage File and any other related
Loan Documents (if not a part of the related Mortgage File) in its possession (other than the documents described in clause (1)
of the definition of “Mortgage File”) to the related Outside Trustee or the Outside Custodian; provided that,
prior to the delivery of any such original documents to the related Outside Trustee or Outside Custodian, the Custodian shall
make and retain photocopies of any and all documents so delivered to the related Outside Trustee or the Outside Custodian; and
provided, further, that, to the extent any instruments of assignment that are part of the Mortgage File have been recorded pursuant
to this Agreement prior to the related Servicing Shift Date, the Trustee shall execute and deliver assignments to the Outside
Trustee.

The
Depositor hereby represents and warrants that the applicable Mortgage Loan Seller has covenanted in the related Mortgage Loan
Purchase Agreement as to each Mortgage Loan (exclusive of any Outside Serviced Mortgage Loan), that if it cannot deliver or cause
to be delivered the documents and/or instruments referred to in clauses (2), (3) and (6) (if recorded) and (15) of the definition
of “Mortgage File” solely because of a delay caused by the public recording or filing office where such document or
instrument has been delivered for recordation or filing, as applicable, a copy of the original certified by the applicable Mortgage
Loan Seller or the title agent to be a true and complete copy of the original thereof submitted for recording, shall be forwarded
to the Custodian. Each assignment referred to in the prior paragraph that is recorded and the file copy of each UCC-3 assignment
referred to in the previous paragraph shall reflect that it should be returned by the public recording or filing office to the
Custodian or its agent following recording (or, alternatively, to the applicable Mortgage Loan Seller or its designee, in which
case the applicable Mortgage Loan Seller shall deliver or cause the delivery of the recorded/filed original to the Custodian promptly
following receipt); provided that, in those instances where the public recording office retains the original assignment
of Mortgage or assignment of Assignment of Leases, the applicable Mortgage Loan Seller or its designee shall obtain and provide
to the Custodian a certified copy of the recorded original. On a monthly basis, at the expense of the applicable Mortgage Loan
Seller, the Custodian shall forward to the Master Servicer a copy of each of the aforementioned assignments following the Custodian’s
receipt thereof.


 


If
the Custodian has received written notice that any of the aforementioned assignments is lost or returned unrecorded or unfiled,
as the case may be, because of a defect therein, then the Custodian shall direct the applicable Mortgage Loan Seller (pursuant
to the Mortgage Loan Purchase Agreement) promptly to prepare or cause the preparation of a substitute therefor or cure such defect
or cause such defect to be cured, as the case may be, and to record or file, or with respect to any assignments that a third party
on the Mortgage Loan Seller’s behalf has agreed to record or file as described above, to deliver to such third party the
substitute or corrected document.


 


(d)             In
connection with the Depositor’s assignment pursuant to Section 2.01(a) of this Agreement, except with respect to
any Outside Serviced Mortgage Loan, the Depositor shall direct the applicable Mortgage Loan Seller (pursuant to the related Mortgage
Loan Purchase Agreement) to deliver to and deposit with (or cause to be delivered to and deposited with) the Master Servicer
within five (5) Business Days after the Closing Date: (i) a copy of the Mortgage File; (ii) all documents and records not otherwise
required to be contained in the Mortgage File that (A) relate to the origination and/or servicing and administration of the
Mortgage Loans and any related Serviced Companion Loan(s), (B) are reasonably necessary for the ongoing administration and/or
servicing of the Mortgage Loans (including any asset summaries related to the Mortgage Loans that were delivered to the Rating
Agencies in connection with the rating of the Certificates) or any related Serviced Companion Loans or for evidencing or enforcing
any of the rights of the holder of the Mortgage Loans or any related Serviced Companion Loans or holders of interests therein,
and (C) are in possession or under control of the applicable Mortgage Loan Seller; and (iii) all unapplied Escrow Payments
and reserve funds in the possession or under control of the applicable Mortgage Loan Seller that relate to such Mortgage Loans
and any related Serviced Companion Loans, together with a statement indicating which Escrow Payments and reserve funds are allocable
to each Mortgage Loan or any related Serviced Companion Loan; provided that copies of any document in the Mortgage File
and any other document, record or item

referred to above in this sentence that, in each case, constitutes a Designated Servicing
Document shall be delivered to the Master Servicer on or before the Closing Date; and provided, further, that the
applicable Mortgage Loan Seller shall not be required to deliver any draft documents, privileged or other related Mortgage Loan
Seller communications, credit underwriting, due diligence analyses or data, or internal worksheets, memoranda, communications
or evaluations. The Master Servicer shall hold all such documents, records and funds on behalf of the Trustee in trust for the
benefit of the Certificateholders (and, insofar as they also relate to a Serviced Companion Loan, on behalf of and for the benefit
of the applicable Serviced Companion Loan Holder). Notwithstanding anything to the contrary, the foregoing provisions of this
Section 2.01(d) shall not apply to the Outside Serviced Mortgage Loans. In addition, each Mortgage Loan Seller is required,
pursuant to the related Mortgage Loan Purchase Agreement, to provide to the Master Servicer the initial data with respect to its
Mortgage Loans for (i) the CREFC® Financial File and the CREFC® Loan Periodic Update File that are required to be prepared
by the Master Servicer pursuant to this Agreement and (ii) the Supplemental Servicer Schedule.


 


(e)             In
connection with the Depositor’s assignment pursuant to subsection (a) above, the Depositor shall deliver, and hereby
represents and warrants that it has delivered, to the Custodian and the Master Servicer, on or before the Closing Date, a fully
executed original counterpart of each Mortgage Loan Purchase Agreement, as in full force and effect, without amendment or modification,
on the Closing Date.


 


(f)             With
respect to a Serviced Loan Combination, the Custodian shall also hold the related Mortgage File for the use and benefit of the
related Serviced Companion Loan Holder(s).


 


(g)            The
parties to this Agreement acknowledge and agree, with respect to the Outside Serviced Mortgage Loans, that the Trust assumes the
obligations and rights of the holder of each Outside Serviced Mortgage Loan under the respective Co-Lender Agreement and/or Outside
Servicing Agreement.


 


(h)             It
is not intended that this Agreement create a partnership or a joint-stock association.


 


(i)             The
parties to this Agreement acknowledge that each Mortgage Loan Purchase Agreement provides that: (1) within sixty (60) days after
the Closing Date, the related Mortgage Loan Seller is required to deliver or cause to be delivered the Diligence File for each
of its Mortgage Loans to the Depositor by uploading such Diligence Files to the Designated Site; and (2) promptly upon completion
of such delivery of the Diligence Files (but in no event later than sixty (60) days after the Closing Date), the applicable Mortgage
Loan Seller is required to provide to the Depositor (with a copy (which may be sent by email if and to the extent provided for
in Section 12.04 of this Agreement) to each of the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator,
the Custodian, the Controlling Class Representative, the Asset Representations Reviewer and the Operating Advisor) an officer’s
certificate signed by such Mortgage Loan Seller certifying that the electronic copies of the documents uploaded to the Designated
Site constitute all documents required under the definition of “Diligence File” and such Diligence Files are organized
and categorized in accordance with the electronic file structure reasonably requested by the Depositor (the “Diligence
File Certification”). The Depositor shall


 






    	-143- 



     


    

 


have no responsibility for determining whether any Diligence Files delivered
to it are complete and shall have no liability to the Trust or the Certificateholders for the failure of any Mortgage Loan Seller
to deliver a Diligence File (or a complete Diligence File) to the Depositor.


 


(j)              Within
1 Business Day after the Closing Date, the Depositor shall deliver to the Master Servicer the Initial Schedule AL File and the
Initial Schedule AL Additional File in XML Format and Excel format at the following email address: NoticeAdmin@midlandls.com.


 


Section 2.02     Acceptance
by the Trustee, the Custodian and the Certificate Administrator.


 


(a)            The
Trustee, by its execution and delivery of this Agreement, hereby accepts receipt, directly or through the Custodian on its behalf,
of (i) the Mortgage Loans and all documents delivered to it that constitute portions of the related Mortgage Files and (ii) all
other assets delivered to it and included in the Trust Fund, in good faith and without notice of any adverse claim, and declares
that it or the Custodian on its behalf holds and will hold such documents and any other documents subsequently received by it
that constitute portions of the Mortgage Files, and that the Custodian on behalf of the Trustee holds and will hold the Mortgage
Loans and such other assets, together with any other assets subsequently delivered to it that are to be included in the Trust
Fund, in trust for the exclusive use and benefit of all present and future Certificateholders and, if applicable, the Serviced
Companion Loan Holders pursuant to Section 2.01(f) of this Agreement. With respect to each Serviced Loan Combination,
the Custodian shall also hold the portion of such Mortgage File that relates to the Serviced Companion Loan in such Loan Combination
in trust for the use and benefit of the related Serviced Companion Loan Holder. In connection with the foregoing, the Certificate
Administrator, as the initial Custodian, hereby certifies to each of the other parties hereto, the applicable Mortgage Loan Seller,
each Underwriter and each Initial Purchaser that, as to each Mortgage Loan, (i) all documents specified in clause (1) of
the definition of “Mortgage File” are in its possession, and (ii) the original Note (or, if accompanied by a
lost note affidavit, the copy of such Note) received by it with respect to such Mortgage Loan has been reviewed by it and
(A) appears regular on its face (handwritten additions, changes or corrections shall not constitute irregularities if initialed
by the Mortgagor), (B) appears to have been executed (where appropriate) and (C) purports to relate to such Mortgage
Loan.


 


(b)            On
or about the 60th day following the Closing Date (and, if any exceptions are noted, again on or about the 90th
day following the Closing Date and monthly thereafter until the earliest of (i) the second anniversary of the Closing
Date, (ii) the day on which all exceptions have been removed and (iii) the day on which the applicable Mortgage Loan
Seller has repurchased or substituted for the last affected Mortgage Loan), the Custodian shall review the documents delivered
to it with respect to each Mortgage Loan, and the Custodian shall, subject to Sections 2.01(c), 2.02(c) and
2.02(d) of this Agreement and the terms of the respective Mortgage Loan Purchase Agreements, certify in writing (substantially
in the form of Exhibit N to this Agreement) to each of the other parties hereto, the applicable Mortgage Loan Seller,
each Underwriter and each Initial Purchaser (and upon request, in the case of a Serviced Loan Combination, to the related Serviced
Companion Loan Holder) that, as to each Mortgage Loan then subject to this Agreement (except as specifically identified in any
exception report annexed to such certification, which exception report shall also be available in electronic format (including
Excel-compatible format) upon request): (i) all documents specified in clauses (1), (2), (3), (4)


 






    	-144- 



     


    

 


(other than with respect
to an Outside Serviced Mortgage Loan), (5), (6) (provided that the Custodian has been notified of any related modification), (7),
(15) and (20) (for any Mortgage Loan that is part of a Loan Combination) of the definition of “Mortgage File” are
in its possession; (ii) the recordation/filing contemplated by Section 2.01(c) of this Agreement has been
completed (based solely on receipt by the Custodian (whether that is the Certificate Administrator or any other Custodian appointed
by it) of the particular recorded/filed documents); (iii) all documents received by the Custodian with respect to such Mortgage
Loan have been reviewed by the Custodian and (A) appear regular on their face (handwritten additions, changes or corrections
shall not constitute irregularities if initialed by the Mortgagor), (B) appear to have been executed (where appropriate)
and (C) purport to relate to such Mortgage Loan; and (iv) based on the examinations referred to in Section 2.02(a)
of this Agreement and this Section 2.02(b) and only as to the foregoing documents (together with any Loan Agreement
that has been delivered by the related Mortgage Loan Seller), the information set forth in the Mortgage Loan Schedule with respect
to the items specified in clauses (iv) and (v)(B) of the definition of “Mortgage Loan Schedule” accurately reflects
the information set forth in the Mortgage File. With respect to the items listed in clauses (2), (3), (4) and (6) of the definition
of “Mortgage File” if the original of such document is not in the Custodian’s possession because it has not
been returned from the applicable recording office, then the Custodian’s certification prepared pursuant to this Section 2.02(b)
should indicate the absence of such original. In addition, as it relates to the Outside Serviced Mortgage Loans, with respect
to the items listed in clauses (1), (2), (3), (4), (5), (6), (7), (15) and (20) of the definition of “Mortgage File”,
the Custodian’s certification prepared pursuant to this Section 2.02(b) should indicate the absence of such document:
(i) in the case of the item listed in clause (1) of the definition of “Mortgage File”, unless the Custodian is in
possession of the original of such document; and (ii) in the case of the items listed in clauses (2), (3), (4), (5), (6), (7),
(15) and (20) of the definition of “Mortgage File”, unless the Custodian is in possession of a copy of such document.
If the Custodian’s obligation to deliver the certifications contemplated in this subsection terminates because two years
have elapsed since the Closing Date, the Certificate Administrator shall deliver (or cause any other Custodian appointed by it
to deliver) a comparable certification to any party hereto, the Serviced Companion Loan Holder and any Underwriter and any Initial
Purchaser on request.


 


(c)             It
is acknowledged that none of the Trustee, the Master Servicer, the Special Servicer, the Certificate Administrator or the Custodian
is under any duty or obligation to inspect, review or examine any of the documents, instruments, certificates or other papers
relating to the Loans delivered to it to determine that the same are valid, legal, effective, genuine, binding, enforceable, sufficient
or appropriate for the represented purpose or that they are other than what they purport to be on their face. Furthermore, none
of the Trustee, the Master Servicer, the Special Servicer, the Certificate Administrator or the Custodian shall have any responsibility
for determining whether the text of any assignment or endorsement is in proper or recordable form, whether the requisite recording
of any document is in accordance with the requirements of any applicable jurisdiction, or whether a blanket assignment is permitted
in any applicable jurisdiction.


 


(d)            The
parties hereto hereby agree that the scope of the Custodian’s review of the Mortgage Files is limited solely to confirming
that the documents specified in clauses (1), (2), (3), (4) (other than with respect to an Outside Serviced Mortgage Loan), (5),
(6) (provided that the Custodian has been notified of any related modification), (7), (15) and (20) (for any Mortgage Loan that
is part of a Loan Combination) of the definition of “Mortgage File” have been received,


 






    	-145- 



     


    

 


appear regular on their face
and such additional information as will be necessary for delivering the certifications required by Sections 2.02(a)
and 2.02(b) of this Agreement, and such review is in no way intended to, nor shall it be used to, verify the content of
any collateral descriptions included in any data tapes and shall not otherwise directly or indirectly be reflected in any offering
document. Any review of the Mortgage Files by the Custodian and any certification with respect thereto is not intended to, and
shall not be deemed by the parties to this Agreement 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, under the Exchange Act. Any recipient
of the Custodian’s certification or a copy thereof by its receipt thereof is deemed to agree, and each party to this Agreement
hereby agrees, that it shall not share such certification with any NRSRO or any party not addressed on such certification. Notwithstanding
the foregoing, nothing in this Section 2.02(d) shall relieve any party to this Agreement from its obligation to deliver
information to the Rating Agencies as required under and in accordance with the terms of this Agreement.


 


(e)            If,
after the Closing Date, the Depositor comes into possession of any documents or records that constitute part of the Mortgage File
or Servicing File for any Mortgage Loan, the Depositor shall promptly deliver such document to the Custodian with a copy to the
Master Servicer (if it constitutes part of the Servicing File).


 


Section 2.03     Mortgage
Loan Sellers’ Repurchase, Substitution or Cures of Mortgage Loans for Document Defects in Mortgage Files and Breaches of
Representations and Warranties.


 


(a)            If
(i) any party hereto (other than the Asset Representations Reviewer) (A) discovers or receives notice alleging that
any document constituting a part of a Mortgage File has not been properly executed, is missing, contains information that does
not conform in any material respect with the corresponding information set forth in the Mortgage Loan Schedule, or does not appear
to be regular on its face (each, a “Document Defect”) or (B) discovers or receives notice alleging a breach
of any representation or warranty of the applicable Mortgage Loan Seller made pursuant to Section 6(c) of the related Mortgage
Loan Purchase Agreement with respect to any Mortgage Loan (a “Breach”) or (ii) the Special Servicer or
the Depositor receives a Repurchase Request, then such Person shall give prompt written notice thereof to the applicable Mortgage
Loan Seller, the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event),
the other parties hereto, any related Serviced Companion Loan Holder (if applicable) and, for posting to the Rule 17g-5 Information
Provider’s Website pursuant to Section 12.13 of this Agreement, the Rule 17g-5 Information Provider (to the extent
notice has not previously been delivered to such Persons pursuant to this sentence). If any such Document Defect or Breach materially
and adversely affects, or any such Document Defect is deemed in accordance with Section 2.03(b) of this Agreement
to materially and adversely affect, the value of the related Mortgage Loan, the value of the related Mortgaged Property (or any
related REO Property) or the interests of the Trustee or any Certificateholder in the related Mortgage Loan or the related Mortgaged
Property (or any related REO Property) or causes any Mortgage Loan to fail to be a Qualified Mortgage, then such Document Defect
shall constitute a “Material Document Defect” or such Breach shall constitute a “Material Breach”,
as the case may be. The Enforcing Servicer shall determine, with respect to any affected Mortgage Loan or REO Mortgage Loan, whether
a Document Defect is a Material Document Defect or a Breach is a Material Breach. If such Document Defect or Breach has been determined
to be a Material Defect, then the Enforcing


 






    	-146- 



     


    

 


Servicer shall give prompt written notice to the other parties hereto, the Controlling
Class Representative (prior to the occurrence and continuance of a Consultation Termination Event), and the applicable Mortgage
Loan Seller (and in the case of the Mortgage Loans sold to the Depositor by LCF, with simultaneous notice to and demand on the
LC Guarantors, as guarantors of certain of LCF’s obligations under the LCF Mortgage Loan Purchase Agreement, pursuant to
the LCF Mortgage Loan Purchase Agreement) (a) notifying such parties of the existence of such Material Defect and (b) demanding
that the applicable Mortgage Loan Seller, not later than 90 days from the earlier of the applicable Mortgage Loan Seller’s
(x) discovery of, and (y) receipt of notice of, and receipt of a demand to take action with respect to, such Material Defect (or,
in the case of a Material Defect relating to a Mortgage Loan not being a Qualified Mortgage, not later than 90 days from
any party discovering such Material Defect), cure the same in all material respects (which cure shall include payment of losses
and any Additional Trust Fund Expenses associated therewith (including, if applicable, the amount of any fees of the Asset Representations
Reviewer payable pursuant to the related Mortgage Loan Purchase Agreement attributable to the Asset Review of such Mortgage Loan)) or,
if such Material Defect cannot be cured within such 90 day period, either (before the end of such 90-day period) (i) repurchase
the affected Mortgage Loan or any related REO Property (or the Trust’s interest therein with respect to any Outside Serviced
Mortgage Loan) at the applicable Purchase Price by wire transfer of immediately available funds to the Collection Account or (ii) substitute
a Qualified Substitute Mortgage Loan for such affected Mortgage Loan (provided that in no event shall any such substitution
occur on or after the second anniversary of the Closing Date) and pay the Master Servicer for deposit into the Collection Account,
any Substitution Shortfall Amount in connection therewith, all in conformity with the applicable Mortgage Loan Purchase Agreement
and this Agreement; provided, however, that if (i) such Material Defect is capable of being cured but not within
such 90 day period, (ii) such Material Defect is not related to any Mortgage Loan’s not being a Qualified Mortgage
and (iii) the applicable Mortgage Loan Seller has commenced and is diligently proceeding with the cure of such Material Defect
within such 90 day period, then such Mortgage Loan Seller shall have an additional 90 days to complete such cure or,
in the event of a failure to so cure, to complete such repurchase or substitution (it being understood and agreed that, in connection
with such Mortgage Loan Seller’s receiving such additional 90 day period, such Mortgage Loan Seller shall deliver an
Officer’s Certificate to the Trustee, the Master Servicer, the Special Servicer and the Certificate Administrator setting
forth the reasons such Material Defect is not capable of being cured within the initial 90 day period and what actions such
Mortgage Loan Seller is pursuing in connection with the cure thereof and stating that such Mortgage Loan Seller anticipates that
such Material Defect will be cured within such additional 90 day period); and provided, further, that, if any
such Material Defect is still not cured after the initial 90 day period and any such additional 90 day period solely
due to the failure of such Mortgage Loan Seller to have received the recorded document, then such Mortgage Loan Seller shall be
entitled to continue to defer its cure, repurchase and/or substitution obligations in respect of such Material Defect so long
as such Mortgage Loan Seller certifies to the Trustee, the Master Servicer, the Special Servicer and the Certificate Administrator
every 30 days thereafter that the Material Defect is still in effect solely because of its failure to have received the recorded
document and that such Mortgage Loan Seller is diligently pursuing the cure of such defect (specifying the actions being taken),
except that no such deferral of cure, repurchase or substitution may continue beyond the date that is 18 months following the
Closing Date. If the affected Mortgage Loan is to be repurchased, the Master Servicer shall designate the Collection Account as
the account to which funds in the amount of the Purchase Price are to be wired. If the affected Mortgage Loan is to be substituted
for, the Master Servicer


 






    	-147- 



     


    

 


shall designate the Collection Account as the account to which funds in the amount of the Substitution
Shortfall Amount are to be wired. Any such repurchase or substitution of a Mortgage Loan shall be on a whole loan, servicing released
basis. Monthly Payments due with respect to each Qualified Substitute Mortgage Loan (if any) after the related Due Date in the
month of substitution, and Monthly Payments due with respect to each Mortgage Loan being repurchased or replaced after the related
Cut-Off Date and received by the Master Servicer or the Special Servicer on behalf of the Trust on or prior to the related date
of repurchase or substitution, shall be part of the Trust Fund. Monthly Payments due with respect to each Qualified Substitute
Mortgage Loan (if any) on or prior to the related Due Date in the month of substitution, and Monthly Payments due with respect
to each Mortgage Loan being repurchased or replaced and received by the Master Servicer or the Special Servicer on behalf of the
Trust after the related date of repurchase or substitution, shall not be part of the Trust Fund and are to be remitted by the
Master Servicer to the Mortgage Loan Seller effecting the related repurchase or substitution promptly following receipt. From
and after the date of substitution, each Qualified Substitute Mortgage Loan, if any, that has been substituted shall be deemed
to constitute a “Mortgage Loan” hereunder for all purposes. No mortgage loan may be substituted for a Defective Mortgage
Loan as contemplated by this Section 2.03(a) if the Mortgage Loan to be replaced was itself a Qualified Substitute Mortgage
Loan that had replaced a prior Mortgage Loan, in which case, absent a cure (including by the making of a Loss of Value Payment
pursuant to the following paragraph) of the relevant Material Defect, the affected Mortgage Loan will be required to be repurchased.


 


Notwithstanding
the foregoing provisions of this Section 2.03(a), in lieu of the related Mortgage Loan Seller performing its obligations
with respect to any Material Defect as set forth in the preceding paragraph, to the extent that such Mortgage Loan Seller and
the Enforcing Servicer (subject to the consent of the Controlling Class Representative so long as no Control Termination Event
has occurred and is continuing and other than with respect to an Excluded Mortgage Loan), are able to agree upon a cash payment
payable by such Mortgage Loan Seller to the Trust that would be deemed sufficient to compensate the Trust for such Material Defect
(a “Loss of Value Payment”), such Mortgage Loan Seller may elect, in its sole discretion, to pay such Loss
of Value Payment to the Trust, and the amount of such Loss of Value Payment shall be deposited into the Loss of Value Reserve
Fund to be applied in accordance with Section 3.06(c) of this Agreement; provided that a Material Defect as a result
of a Mortgage Loan not constituting a Qualified Mortgage may not be cured by a Loss of Value Payment. In connection with the Special
Servicer’s reaching an agreement with a Mortgage Loan Seller as to a Loss of Value Payment, the Master Servicer shall, upon
the Special Servicer’s request, promptly provide the Special Servicer with a copy of the Servicing File for such Mortgage
Loan and any other information relating to such Mortgage Loan and reasonably requested by the Special Servicer. Any agreement
by the Special Servicer with a Mortgage Loan Seller as to any Loss of Value Payment with respect to a Specially Serviced Loan
shall be subject to the consent of the Controlling Class Representative (so long as no Control Termination Event has occurred
and is continuing and other than with respect to an Excluded Mortgage Loan). The Loss of Value Payment shall include the portion
of any Liquidation Fees payable to the Special Servicer in respect of such Loss of Value Payment and the portion of fees of the
Asset Representations Reviewer attributable to any Asset Review of such Mortgage Loan. Upon its making a Loss of Value Payment,
the related Mortgage Loan Seller shall be deemed to have cured the subject Material Defect in all respects. Provided that such
Loss of Value Payment is made, this paragraph describes the sole remedy available to the Certificateholders or the Trust regarding
any such Material Defect in respect of which such


 






    	-148- 



     


    

 


Loss of Value Payment is accepted, and the related Mortgage Loan Seller shall
not be obligated to repurchase or replace the affected Mortgage Loan or otherwise cure such Material Defect. This paragraph is
intended to apply only to a mutual agreement or settlement between the applicable Mortgage Loan Seller and the Enforcing Servicer,
provided that, prior to any such agreement or settlement, nothing in this paragraph shall preclude the Mortgage Loan Seller
or the Enforcing Servicer, as applicable, from exercising any of its rights related to a Material Defect in the manner and within
the time frames set forth in the related Mortgage Loan Purchase Agreement or this Section 2.03 (excluding this paragraph)
(including any right to cure, repurchase or substitute for such Mortgage Loan).


 


If
(x) a Mortgage Loan is to be repurchased or replaced as described above (a “Defective Mortgage Loan”), (y)
such Defective Mortgage Loan is part of a Cross-Collateralized Group and (z) the applicable Document Defect or Breach does not
constitute a Material Defect as to the other Mortgage Loan(s) that are a part of such Cross-Collateralized Group (the “Other
Crossed Loans”) (without regard to this paragraph), then the applicable Document Defect or Breach (as the case may be)
shall be deemed to constitute a Material Defect as to each such Other Crossed Loan for purposes of the above provisions, and the
related Mortgage Loan Seller shall be obligated to repurchase or replace each such Other Crossed Loan in accordance with the provisions
above unless, in the case of such Breach or Document Defect, as applicable:


 


(A)           the
related Mortgage Loan Seller (at its expense) delivers or causes to be delivered to the Trustee, the Master Servicer and the Special
Servicer an Opinion of Counsel to the effect that such Mortgage Loan Seller’s repurchase or replacement of only the Mortgage
Loan(s) as to which a Material Defect has actually occurred without regard to the provisions of this paragraph (the “Affected
Loan(s)”) and the operation of the remaining provisions of this Section 2.03(a) (i) will not cause either Trust
REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under subpart E, part I of
subchapter J of the Code for federal income tax purposes at any time that any Certificate is outstanding and (ii) will not result
in the imposition of a tax upon either Trust REMIC or the Trust Fund (including but not limited to the tax on “prohibited
transactions” as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section
860G(d) of the Code); and


 


(B)            each
of the following conditions would be satisfied if the related Mortgage Loan Seller were to repurchase or replace only the Affected
Loans and not the Other Crossed Loans:


 


(1)              the
debt service coverage ratio for such Other Crossed Loan(s) (excluding the Affected Loan(s)) for the four calendar quarters immediately
preceding the repurchase or replacement is not less than the lesser of (A) 0.10x below the debt service coverage ratio for the
Cross-Collateralized Group (including the Affected Loan(s)) set forth in Annex A to the Prospectus and (B) the debt service
coverage ratio for the Cross-Collateralized Group (including the Affected Loan(s)) for the four preceding calendar quarters preceding
the repurchase or replacement;


 






    	-149- 



     


    

 


(2)              the
loan-to-value ratio for the Other Crossed Loans (excluding the Affected Loan(s)) is not greater than the greatest of (A) the loan-to-value
ratio, expressed as a whole number percentage (taken to one decimal place), for the Cross-Collateralized Group (including the
Affected Loan(s)) set forth in Annex A to the Prospectus plus 10%, (B) the loan-to-value ratio, expressed as a whole
number percentage (taken to one decimal place), for the Cross-Collateralized Group (including the Affected Loan(s)) at the time
of repurchase or replacement and (C) 75%; and


 


(3)              either
(x) the exercise of remedies against the Primary Collateral of any Mortgage Loan in the Cross-Collateralized Group will not impair
the ability to exercise remedies against the Primary Collateral of the other Mortgage Loans in the Cross-Collateralized Group
or (y) the Loan Documents evidencing and securing the relevant Mortgage Loans have been modified in a manner that complies with
the related Mortgage Loan Purchase Agreement and this Agreement and that removes any threat of impairment of the ability to exercise
remedies against the Primary Collateral of the other Mortgage Loans in the Cross-Collateralized Group as a result of the exercise
of remedies against the Primary Collateral of any Mortgage Loan in the Cross-Collateralized Group.


 


The
determination of the Enforcing Servicer as to whether the conditions set forth above have been satisfied shall be conclusive and
binding in the absence of manifest error on the Certificateholders, other parties to this Agreement and the related Mortgage Loan
Seller. The Enforcing Servicer will be entitled to cause to be delivered, or direct the related Mortgage Loan Seller to cause
to be delivered, to the Enforcing Servicer an Appraisal of any or all of the related Mortgaged Properties for purposes of determining
whether the condition set forth in clause (B)(2) above has been satisfied, in each case at the expense of the related Mortgage
Loan Seller if the scope and cost of the Appraisal is approved by the related Mortgage Loan Seller and, prior to the occurrence
and continuance of a Control Termination Event, the Controlling Class Representative (such approval not to be unreasonably withheld
in each case).


 


With
respect to any Defective Mortgage Loan that forms a part of a Cross-Collateralized Group and as to which the conditions described
in the second preceding paragraph are satisfied, such that the Trust Fund will continue to hold the Other Crossed Loans, the related
Mortgage Loan Seller and the Trustee, as successor to the Depositor, are bound by an agreement (set forth in the related Mortgage
Loan Purchase Agreement) to forbear from enforcing any remedies against the other’s Primary Collateral but each is permitted
to exercise remedies against the Primary Collateral securing its respective Mortgage Loans, including with respect to the Trustee,
the Primary Collateral securing the Affected Loan(s) still held by the Trust Fund. If the exercise of remedies by one such party
would impair the ability of the other such party to exercise its remedies with respect to the Primary Collateral securing the
Affected Loan or the Other Crossed Loans, as the case may be, held by the other such party, then both parties have agreed to forbear
from exercising such remedies unless and until the Loan Documents evidencing and securing the relevant Mortgage Loans can be modified
in a manner that complies with the related Mortgage Loan Purchase Agreement to remove the threat of impairment as a result of
the exercise of remedies. Any reserve or other cash collateral or letters of credit securing any of the Mortgage


 






    	-150- 



     


    

 


Loans that form
a Cross-Collateralized Group shall be allocated between such Mortgage Loans in accordance with the related Loan Documents, or
otherwise on a pro rata basis based upon their outstanding Stated Principal Balances. All other terms of the related Mortgage
Loans shall remain in full force and effect, without any modification thereof. The provisions of this paragraph shall be binding
on all future holders of each Mortgage Loan that forms part of a Cross-Collateralized Group.


 


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


 


To
the extent necessary and appropriate, the Master Servicer or Special Servicer, as applicable, shall execute (pursuant to a limited
power of attorney provided by the Trustee that enables the Master Servicer or Special Servicer, as applicable, to execute) the
modification of the Loan Documents that complies with the applicable Mortgage Loan Purchase Agreement to remove the threat of
impairment of the ability of the Mortgage Loan Seller or the Trust Fund to exercise its remedies with respect to the Primary Collateral
securing the Mortgage Loan(s) held by such party resulting from the exercise of remedies by the other such party; provided
that the Trustee shall not be liable for any misuse of any such power of attorney by the Master Servicer or Special Servicer,
as applicable, or any of its agents or subcontractors. The Master Servicer shall advance all costs and expenses incurred by the
Trustee, the Special Servicer and the Master Servicer with respect to any Cross-Collateralized Group pursuant to this paragraph
and the first, second and third preceding paragraphs, and such advances and interest thereon shall (i) constitute and be reimbursable
as Property Advances and (ii) be included in the calculation of Purchase Price for the Affected Loan(s) to be repurchased or replaced.
Neither the Master Servicer nor the Special Servicer shall be liable to any Certificateholder or any other party hereto if a modification
of the Loan Documents described above cannot be effected for any reason beyond the control of the Master Servicer or the Special
Servicer or should not be effected as determined by the Master Servicer or Special Servicer, as applicable, in accordance with
the Servicing Standard.


 


If
the Master Servicer, the Special Servicer or the Depositor receives a Repurchase Communication of a withdrawal of a Repurchase
Request of which notice has been previously received or given and which withdrawal is by the Person making such Repurchase Request

to the applicable Mortgage Loan Seller, the other parties hereto, the Controlling Class Representative (prior to the occurrence
and continuance of a Consultation Termination Event), any Serviced Companion Loan Holder (if applicable) and, for posting to the
Rule 17g-5 Information Provider’s Website pursuant to Section 12.13 of this Agreement, the Rule 17g-5 Information

Communication that any Mortgage Loan that was subject of a Repurchase Request has
been repurchased or replaced (a “Repurchase”), or that such Repurchase Request has been rejected (a “Repurchase

following paragraph) give written notice of such Repurchase or Repurchase Request Rejection to the other such party, the Depositor,
the applicable Mortgage Loan Seller (unless it is the entity that has repurchased or replaced the subject Mortgage Loan or rejected
such Repurchase Request), and the Certificate Administrator (in each case unless the proposed recipient is the party that notified
the Master Servicer or the Special Servicer, as applicable, thereof).


 


Each
notice of a Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection required to be given
by a party pursuant to this Section 2.03(a) (each, a “Rule 15Ga-1 Notice”) shall be given no later

If
the Trustee, the Master Servicer, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or
the Custodian receives a Repurchase Communication of a Repurchase Request, a Repurchase Request Withdrawal, a Repurchase or a
Repurchase Request Rejection, then such party shall promptly forward such Repurchase Communication of such Repurchase Request,
Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection to the Special Servicer and, prior to the occurrence
and continuance of a Consultation Termination Event, the Controlling Class Representative, and include the following statement

No
Person that is required to provide a Rule 15Ga-1 Notice pursuant to this Section 2.03(a) (a “Rule 15Ga-1
Notice Provider”) shall be required to provide any information in


 






    	-152- 



     


    

 


a Rule 15Ga-1 Notice protected by the attorney-client
privilege or attorney work product doctrines. Each Mortgage Loan Purchase Agreement will provide that (i) any Rule 15Ga-1
Notice provided pursuant to this Section 2.03(a) is so provided only to assist the related Mortgage Loan Seller, the
Depositor and their respective Affiliates to comply with Rule 15Ga-1, 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 Rule 15Ga-1 Notice Provider and (B) no
information provided pursuant to this Section 2.03(a) by a Rule 15Ga-1 Notice Provider in a Rule 15Ga-1 Notice shall
be deemed to constitute a waiver or defense to the exercise of any legal right the Rule 15Ga-1 Notice Provider may have with respect
to the related Mortgage Loan Purchase Agreement, including with respect to any Repurchase Request that is the subject of a Rule
15Ga-1 Notice.


 


On
or before the Closing Date, the Depositor shall deliver to the Master Servicer a copy of each Mortgage Loan Purchase Agreement,
which the Master Servicer shall provide to each Sub-Servicer.


 


(b)            Subject
to the applicable Mortgage Loan Seller’s right to cure as contemplated in this Section 2.03, and further subject
to Section 2.01(b) and Section 2.01(c) of this Agreement, failure of such Mortgage Loan Seller to deliver the
documents referred to in clauses (1), (2), (7), (8), (18) and (19) in the definition of “Mortgage File” in accordance
with this Agreement and the applicable Mortgage Loan Purchase Agreement for any Mortgage Loan shall be deemed a Material Document
Defect; provided, however, that no Document Defect (except a deemed Material Document Defect described above) shall
be considered to be a Material Document Defect unless the document with respect to which the Document Defect exists is required
in connection with an imminent enforcement of the lender’s rights or remedies under the related Mortgage Loan, defending
any claim asserted by any Mortgagor or third party with respect to the Mortgage Loan, establishing the validity or priority of
any lien on any collateral securing the Mortgage Loan or for any immediate significant servicing obligation.


 


(c)             In
connection with any repurchase of, or substitution of a Qualified Substitute Mortgage Loan for, a Mortgage Loan pursuant to this
Section 2.03, the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer
shall each tender to the applicable repurchasing entity, upon delivery to each of them of a receipt executed by the applicable
repurchasing entity evidencing such repurchase or substitution, all portions of the Mortgage File and other documents (including,
without limitation, the Servicing File), and all Escrow Payments and reserve funds, pertaining to such Mortgage Loan possessed
by it, and each document that constitutes a part of the Mortgage File shall be endorsed or assigned to the extent necessary or
appropriate to the applicable Mortgage Loan Seller or its designee in the same manner, but only if the respective documents have
been previously assigned or endorsed to the Trustee, and pursuant to appropriate forms of assignment, substantially similar to
the manner and forms pursuant to which such documents were previously assigned to the Trustee or as otherwise reasonably requested
to effect the retransfer and reconveyance of the Mortgage Loan and the security thereof to the Mortgage Loan Seller or its designee;
provided that such tender by the Trustee, the Certificate Administrator and/or and the Custodian shall be conditioned upon
its receipt from the Master Servicer of a Request for Release and an Officer’s Certificate to the effect that the requirements
for repurchase or substitution have been satisfied. The Master Servicer shall, and is hereby authorized and empowered by the Trustee
to, prepare, execute and deliver in its own name, on behalf of the Certificateholders and the Trustee or any of them, the endorsements
and


 






    	-153- 



     


    

 


assignments contemplated by this Section 2.03(c), and such other instruments as may be necessary or appropriate
to transfer title to an REO Property (including with respect to an Outside Serviced Mortgage Loan) in connection with the repurchase
of, or substitution for, an REO Mortgage Loan and the Trustee shall execute and deliver any powers of attorney necessary to permit
the Master Servicer to do so; provided, however, that the Trustee shall not be held liable for any misuse of any
such power of attorney by the Master Servicer or any of its agents or subcontractors. The parties to this Agreement acknowledge
that the related Mortgage Loan Purchase Agreement provides that in the event a Qualified Substitute Mortgage Loan is substituted
for a Defective Mortgage Loan by the related Mortgage Loan Seller as contemplated by this Section 2.03, the related Mortgage
Loan Seller will be required to deliver to the Custodian the related Mortgage File and to the Master Servicer all Escrow Payments
and reserve funds pertaining to such Qualified Substitute Mortgage Loan possessed by it and a certification to the effect that
such Qualified Substitute Mortgage Loan satisfies all of the requirements of the definition of “Qualified Substitute Mortgage
Loan” in this Agreement.


 


The
parties to this Agreement acknowledge that the related Mortgage Loan Purchase Agreement provides that if any Mortgage Loan is
to be repurchased or replaced as contemplated by this Section 2.03, the related Mortgage Loan Seller will be required to
amend the Mortgage Loan Schedule (as such term is defined in the related Mortgage Loan Purchase Agreement) to reflect the removal
of any deleted Mortgage Loan and, if applicable, the substitution of the related Qualified Substitute Mortgage Loan(s) and deliver
or cause the delivery of such amended Mortgage Loan Schedule (as such term is defined in the related Mortgage Loan Purchase Agreement)
to the parties to this Agreement. Upon any substitution of a Qualified Substitute Mortgage Loan for a deleted Mortgage Loan, such
Qualified Substitute Mortgage Loan shall become part of the Trust Fund and be subject to the terms of this Agreement in all respects.


 


(d)            The
related Mortgage Loan Purchase Agreement provides the sole remedies available to the Certificateholders, or the Trustee on behalf
of the Certificateholders, respecting any Document Defect or Breach with respect to any Mortgage Loan. For purposes of this Agreement,
any purchase, replacement or payment of any Loss of Value Payment by any of the LC Guarantors, on behalf of LCF, of or with respect
to any Mortgage Loan for which LCF is the related Mortgage Loan Seller shall be deemed a purchase, replacement or payment of Loss
of Value Payment, as applicable, by LCF.


 


(e)            [RESERVED]


 


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


 


(ii)            In
the event that any of the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator or
the Operating Advisor (solely in its capacity as operating advisor) determines that a Mortgage Loan should be repurchased or


 






    	-154- 



     


    

 


replaced
due to a Material Defect, or has knowledge of a Material Defect with respect to a Mortgage Loan, then such party shall deliver
prompt written notice of such Material Defect to the Enforcing Servicer identifying the applicable Mortgage Loan and setting forth
the basis for such allegation (a “PSA Party Repurchase Request”). Notwithstanding anything to the contrary
in the first sentence of this clause (ii) or any other provision of this Agreement, the Trustee may, but is not obligated
to, make a determination that a Mortgage Loan should be repurchased or replaced due to a Material Defect. The Enforcing Servicer
shall promptly forward such PSA Party Repurchase Request to the applicable Mortgage Loan Seller and each other party to this Agreement.
Subject to subsections (g), (h), (i), (j) and (k) of this Section 2.03, the Enforcing Servicer shall act as the Enforcing
Party and enforce the rights of the Trust against the related Mortgage Loan Seller with respect to each Repurchase Request. The
Enforcing Servicer shall enforce the obligations of the Mortgage Loan Sellers under the Mortgage Loan Purchase Agreements (including,
without limitation, obligations resulting from a Material Defect) pursuant to the terms of this Agreement and the Mortgage Loan
Purchase Agreements. Subject to the provisions of the applicable Mortgage Loan Purchase Agreement and this Agreement, such enforcement,
including, without limitation, the legal prosecution of claims, if any, shall be carried out in such form, to such extent and
at such time as the Enforcing Servicer would require were it, in its individual capacity, the owner of the affected Mortgage Loan,
and in accordance with the Servicing Standard. Any costs incurred by the Enforcing Servicer with respect to the enforcement of
the obligations of a Mortgage Loan Seller under the applicable Mortgage Loan Purchase Agreement shall be deemed to be Property
Advances, to the extent not recovered from the Mortgage Loan Seller or the applicable Requesting Certificateholder and/or Consultation
Requesting Certificateholder.


 


(iii)           In
the event the Repurchase Request is not Resolved within 180 days after the Mortgage Loan Seller receives the Repurchase Request
(a “Resolution Failure”), then the provisions described in Section 2.03(g) below shall apply. Receipt
of the Repurchase Request shall be deemed to occur two (2) Business Days after the Repurchase Request is sent to the related Mortgage
Loan Seller in a commercially reasonable manner. The fact that a Repurchase Request has been Resolved pursuant to clause (vi)
of the definition of “Resolved” shall not preclude the Enforcing Servicer from exercising any of its rights related
to a Material Defect in the manner and timing otherwise set forth in this Agreement, in the related Mortgage Loan Purchase Agreement
or as provided by law.


 


(g)            (i)  After
a Resolution Failure occurs with respect to a Repurchase Request regarding a Mortgage Loan (whether the Repurchase Request was
initiated by an Initial Requesting Certificateholder or by a party to this Agreement), the Enforcing Servicer shall send a notice
(a “Proposed Course of Action Notice”) to the Initial Requesting Certificateholder, if any, to the address
specified in the Initial Requesting Certificateholder’s Repurchase Request, and to the Certificate Administrator who shall
make such notice available to all other Certificateholders and Certificate Owners by posting such notice on the Certificate Administrator’s
Website indicating the Enforcing Servicer’s intended course of action with respect to the Repurchase Request. If (a) the
Enforcing Servicer’s intended course of action with respect to the Repurchase Request does not involve pursuing further
action to exercise rights against the applicable Mortgage Loan Seller with respect to the Repurchase Request, or (b) the
Enforcing Servicer’s intended course of action is to pursue further action to exercise rights against the related Mortgage
Loan Seller with respect


 






    	-155- 



     


    

 


to the Repurchase Request but a Requesting Certificateholder does not agree with the course of action
selected by the Enforcing Servicer and, in the case of clause (a) or (b), a Requesting Certificateholder wishes to exercise its
right to refer the matter to mediation (including non-binding arbitration) or arbitration, if any, then a Requesting Certificateholder
may deliver to the Enforcing Servicer a written notice (a “Preliminary Dispute Resolution Election Notice”)
within 30 days from the date the Proposed Course of Action Notice was posted on the Certificate Administrator’s Website
(the 30th day following the date of posting, the “Dispute Resolution Cut-off Date”) indicating its intent to
exercise its right to refer the matter to either mediation (including non-binding arbitration) or arbitration. In addition, any
Certificateholder or Certificate Owner may deliver, prior to the Dispute Resolution Cut-off Date, a written notice (a “Consultation
Election Notice”) requesting the right to participate in any Dispute Resolution Consultation (as defined in clause
(iii) below) that is conducted by the Enforcing Servicer following the Enforcing Servicer’s receipt of a Preliminary
Dispute Resolution Election Notice as provided in clause (iii) below.


 


(ii)            If
no Requesting Certificateholder delivers a Preliminary Dispute Resolution Election Notice prior to the Dispute Resolution Cut-off
Date, then no Certificateholder or Certificate Owner shall have the right to refer the Repurchase Request to mediation or arbitration,
and the Enforcing Servicer shall be the sole party obligated and entitled to determine a course of action, including, but not
limited to, enforcing the Trust’s rights against the related Mortgage Loan Seller, subject to any consent or consultation
rights of the Directing Holder pursuant to Section 6.09.


 


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


 


(iv)           If,
following the Dispute Resolution Consultation, no Requesting Certificateholder or Consultation Requesting Certificateholder timely
delivers a Final Dispute Resolution Election Notice to the Enforcing Servicer, then no Certificateholder or Certificate Owner
shall have any further right to refer the Repurchase Request to mediation or arbitration, and the Enforcing Servicer shall be
the sole party obligated and entitled to determine a course of action including, but not limited to, enforcing the Trust’s
rights


 






    	-156- 



     


    

 


against the related Mortgage Loan Seller, subject to any consent or consultation rights of the Directing Holder.


 


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


 


(vi)           Notwithstanding
the foregoing, the dispute resolution provisions described above under this Section 2.03(g) shall not apply, and the Enforcing
Servicer shall be the sole party entitled to enforce the Trust’s rights against the related Mortgage Loan Seller, if the
Enforcing Servicer has commenced litigation with respect to the Repurchase Request, or determines in accordance with the Servicing
Standard that it is in the best interest of Certificateholders to commence litigation with respect to the Repurchase Request to
avoid the running of any applicable statute of limitations.


 


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


 






    	-157- 



     


    

 


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


 


(ix)            The
Requesting Certificateholders or Consultation Requesting Certificateholders are entitled to elect either mediation or arbitration
with respect to a Repurchase Request in their sole discretion; provided, however, no Requesting Certificateholder or Consultation
Requesting Certificateholder shall be entitled to then utilize the alternative method in the event that the initial method is
unsuccessful, and no other Certificateholder or Certificate Owner shall be entitled to elect either arbitration or mediation in
the event a mediation or arbitration is undertaken with respect to such Repurchase Request.


 


(h)            If
the Enforcing Party selects mediation (including non-binding arbitration), the following provisions shall apply:


 


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


 


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


 


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


 


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


 


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


 


(vi)           Out-of-pocket
costs and expenses of the Enforcing Servicer for mediation or arbitration, to the extent not agreed to be paid by the Enforcing
Party or another party (in


 






    	-158- 



     


    

 


the case of mediation) or allocated to the Enforcing Party or another party (in the case of arbitration),
shall be reimbursable as expenses of the Trust Fund payable out of the Collection Account pursuant to Section 3.06(a) of
this Agreement.


 


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


 


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


 


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


 


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


 


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


 


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


 






    	-159- 



     


    

 


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


 


(vii)          By
selecting arbitration, the Enforcing Party is waiving its right to sue in court, including the right to a trial by jury.


 


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


 


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


 


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


 


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


 


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


 






    	-160- 



     


    

 


regulatory
requirement or court order. If any party to a resolution procedure receives a subpoena or other request for information from a
third party (other than a governmental regulatory body) for such confidential information, the recipient shall promptly notify
the other party to the resolution procedure and shall provide the other party with a reasonable opportunity to object to the production
of its confidential information.


 


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

Requesting Certificateholder.

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


 


(vi)           The
Trust (or the Enforcing Servicer or a trustee, acting on its behalf), the Depositor or any Mortgage Loan Seller shall be permitted
to redact any personally identifiable customer information included in any information provided for purposes of any mediation
or arbitration. Each party to the proceedings shall be required to agree to keep confidential the details related to the Repurchase
Request and the dispute resolution identified in connection with such procedures; provided, however, that (1) the
Certificateholders shall be permitted to communicate prior to the commencement of any such proceedings to the extent provided
in Section 5.07, (2) to the extent that the Enforcing Servicer is required under Section 2.03(a) to provide any
Rule 15Ga-1 Notice in connection with such Repurchase Request, the Enforcing Servicer shall be permitted to include in such Rule
15Ga-1 Notice the information required pursuant to Section 2.03(a) and (3) the applicable Mortgage Loan Seller shall be
permitted to disclose information related to the Repurchase Request to the extent necessary to comply with its obligations under
Rule 15Ga-1 or Item 1104 of Regulation AB.

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


 


(viii)         Any
out-of-pocket expenses required to be borne by or allocated to the Enforcing Servicer in a mediation or arbitration shall be reimbursable
as expenses of the Trust Fund payable out of the Collection Account pursuant to Section 3.06(a) of this Agreement.

of the related Co-Lender Agreement), including, without limitation, with respect to each Mortgage Loan and Serviced Companion

following the date of receipt of such partial principal prepayment. Unless otherwise provided in the related Loan Documents, the
Master Servicer shall apply any amounts received on “government securities” within the meaning of Section 2(a)(16)

shall not be redeemed by the Master Servicer prior to the maturity thereof) in respect of such a Serviced Loan being defeased
pursuant to its terms to the principal balance of and interest on such Serviced Loan as of the Due Date immediately following
the receipt of such amounts. If with respect to any Serviced Loan the related Loan Documents permit the lender, at its option,
prior to an event of default under the related Serviced Loan, to apply amounts held in any reserve account as a prepayment or
to hold such amounts in a reserve account, the Master Servicer shall hold such amounts in the applicable reserve account and may
not apply such amounts as a prepayment until the occurrence of an event of default under the related Serviced Loan; provided
that any such amounts may be used, if permitted under the related Loan Documents, to defease the related Serviced Loan or,
upon an event of default under the related Serviced Loan, to prepay the Serviced Loan.

Depositor, the Master Servicer shall provide a copy of the applicable Mortgage Loan Purchase Agreement to the related Sub-Servicer,
and that such Sub-Servicer shall notify the Master Servicer in writing within five (5) Business Days after such Sub-Servicer discovers
or receives notice alleging a Document Defect or a Breach or receives a Repurchase Communication of a Repurchase Request, a Repurchase
Request Withdrawal, a Repurchase or a Repurchase Request Rejection; (v) the Master Servicer shall notify the applicable Mortgage
Loan Seller of any such agreement (other than any Sub-Servicing Agreement in place on the Closing Date with a Mortgage Loan Seller
Sub-Servicer); (vi) any assignment of such Sub-Servicing Agreement by the related Sub-Servicer (other than an assignment to the
Master Servicer) shall be subject to the prior written consent of the Depositor (which consent shall not be unreasonably withheld,
conditioned or delayed); (vii) any amendment or modification of such Sub-Servicing Agreement shall be subject to the prior written
consent of the Depositor (which consent shall not be unreasonably withheld, conditioned or delayed) if the Master Servicer determines

the Master Servicer, or by any successor Master Servicer without cost or obligation to the assuming party or the Trust Fund, upon
the assumption by such party of the obligations of the Master Servicer pursuant to Section 7.02 hereof; (ix) any such Sub-Servicing

herein) none of the Trust, the Trustee, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator,
the Master Servicer or Special Servicer, as applicable, any successor master servicer or special servicer or any Certificateholder
(or the related Companion Loan Holder, if applicable) shall have any duties under such Sub-Servicing Agreement or any liabilities
arising therefrom; (ix) any such Sub-Servicing Agreement shall provide that the Sub-Servicer shall be in default under the related
Sub-Servicing Agreement and such Sub-Servicing Agreement shall be terminated (unless such default is waived by the Depositor in
writing) if the Sub-Servicer fails (A) to deliver by the due date (which may take into account any grace period permitted
pursuant to this Agreement) any Exchange Act reporting items required to be delivered to the Master Servicer, the Certificate
Administrator or the Depositor under Article X or under the Sub-Servicing Agreement or to the master servicer under any
other pooling and servicing agreement that the Depositor is a party to, or (B) to perform in any material respect any of
its covenants or obligations contained in the Sub-Servicing Agreement regarding creating, obtaining or delivering any Exchange

Reviewer or any of their respective Risk Retention Affiliates. Any such Sub-Servicing Agreement may permit the Sub-Servicer to
delegate its duties to agents or subcontractors so long as the related agreements or arrangements with such agents or subcontractors
are consistent with the provisions of this Section 3.01(c). The Master Servicer shall be responsible for paying the
servicing fees of any Sub-Servicer retained by it. The Master Servicer shall, upon request, provide a copy of each Sub-Servicing
Agreement (and any assignment thereof) entered into by it to the Depositor. A Sub-Servicer may be an affiliate of the Depositor,
the Master Servicer or the Special Servicer. The Special Servicer shall not appoint sub-servicers with respect to any of its servicing
obligations and duties under this Agreement.

the Sub-Servicer, except as set forth in Section 3.01(d) of this Agreement and no provision herein may be construed
so as to require the Trust Fund to indemnify any such Sub-Servicer.


 


As

Sub-Servicing Agreement (except that, to the extent provided in Article X hereof, the Master Servicer shall be required
only to use commercially reasonable efforts to cause any Mortgage Loan Seller Sub-Servicer to comply with the requirements of
Article X hereof). Such enforcement, including, without limitation, the legal prosecution of claims, termination of Sub-Servicing
Agreements in accordance with their respective terms and the pursuit of other appropriate remedies, shall be in such form and
carried out to such an extent and at such time as is in accordance with the Servicing Standard and the terms of this Agreement.
The Master Servicer shall have the right to remove a Sub-Servicer retained by it in accordance with the terms of the related Sub-Servicing
Agreement.


 


(d)            If
the Trustee or any successor Master Servicer assumes the obligations of the Master Servicer in accordance with Section 7.02,
the Trustee or such successor, as applicable, to the extent necessary to permit the Trustee or such successor, as applicable,
to carry out the provisions of Section 7.02, shall, without act or deed on the part of the Trustee or such successor,

by the Master Servicer pursuant to Section 3.01(c) of this Agreement. In such event, the Trustee or the successor
Master Servicer, as applicable, shall be deemed to have assumed all of the Master Servicer’s interest therein (but not any
liabilities or obligations in respect of acts or omissions of the Master Servicer prior to such deemed assumption) and to have
replaced the Master Servicer as a party to such Sub-Servicing Agreement to the same extent as if such Sub-Servicing Agreement
had been assigned to the Trustee or such successor Master Servicer, as applicable, except that the Master Servicer shall not thereby
be relieved of any liability or obligations under such Sub-Servicing Agreement that accrued prior to the succession of the Trustee
or the successor Master Servicer, as applicable.

Furthermore, to the extent not otherwise expressly included herein, any provisions required to be included herein pursuant to
any Co-Lender Agreement for a Serviced Loan Combination are deemed incorporated herein by reference, and the parties hereto shall
comply with those provisions as if set forth herein in full. In the event of any conflict between this Agreement and a Co-Lender
Agreement with respect to a Serviced Pari Passu Loan Combination, the terms of such Co-Lender Agreement shall control with respect
to such Serviced Pari Passu Loan Combination.


 


With
respect to any Serviced Outside Controlled Mortgage Loan (including any Servicing Shift Mortgage Loan prior to the related Servicing
Shift Date), subject to the rights of the Controlling Class Representative under this Agreement and any applicable consultation
rights of the Operating Advisor (to the extent set forth in Section 3.29(f)), the Master Servicer (if such Serviced Outside
Controlled Mortgage Loan is a Performing Serviced Loan and the matter does not involve a Major Decision or Special Servicer Decision)
or the Special Servicer (if such Serviced Outside Controlled Mortgage Loan is a Specially Serviced Loan or if such Serviced Outside
Controlled Mortgage Loan is a Performing Serviced Loan and the matter involves a Major Decision or Special Servicer Decision)
shall be entitled to exercise the rights and powers granted under the related Co-Lender Agreement to the “Non-Controlling
Note Holder” (as such term or any analogous term is defined in the related Co-Lender Agreement).


 


(f)       
     Notwithstanding anything to the contrary herein, (a) at no time shall the Master Servicer or
the Trustee be required to make any P&I Advance on any Companion Loan and (b) if the Mortgage Loan (or the related REO
Property) that is part of a Serviced Loan Combination is no longer part of the Trust Fund, neither the Master Servicer nor
the Trustee, as


 






    	-180- 



     


    

 


the case may be, shall have any obligation to
make any Property Advance on such Serviced Loan Combination. If pursuant to the foregoing sentence, the Master Servicer does not
intend to make a Property Advance with respect to a Serviced Loan Combination that the Master Servicer would have made if the
related Mortgage Loan or REO Property were still part of the Trust Fund, the Master Servicer shall promptly notify the holder
of the related Serviced Companion Loan of its intention to no longer make such Property Advances and shall additionally promptly
notify such holder of any required Property Advance it would have otherwise made upon becoming aware of the need for such Property
Advance. Additionally, at the time the Mortgage Loan relating to a Serviced Loan Combination is removed from the Trust Fund, the
Master Servicer shall deliver to the related Serviced Companion Loan Holder (or the master servicer of any securitization of the
related Serviced Companion Loan) (i) a copy of the most recent inspection report and the inspection report for the prior calendar
year, (ii) copies of all financial statements collected from the related borrower for the most recent calendar year and the prior
calendar year, (iii) a copy of the most recent Appraisal and any other Appraisal done in the prior year and (iv) a copy of all
tax and insurance bills for the current calendar year and the prior calendar year.


 


(g)            Notwithstanding
anything herein to the contrary, the parties hereto acknowledge and agree that the Master Servicer’s and the Special Servicer’s
obligations and responsibilities hereunder and the Master Servicer’s and the Special Servicer’s authority with respect
to each Outside Serviced Mortgage Loan and each Outside Serviced Companion Loan related to the Outside Serviced Mortgage Loans
are limited by and subject to the terms of the related Co-Lender Agreement and this Agreement and the rights of the related Outside
Servicer and the related Outside Special Servicer with respect thereto under the applicable Outside Servicing Agreement. The parties
further recognize the respective rights and obligations of the related Outside Trustee and/or the Outside Serviced Companion Loan
Holders (or the representatives thereof) under each respective Co-Lender Agreement including with respect to the allocation of
collections on or in respect of an Outside Serviced Loan Combination in accordance with the related Co-Lender Agreement. The Master
Servicer shall cooperate with the Certificate Administrator, on behalf of the Trust, in connection with the enforcement of the
rights by the Trustee (as holder of the Outside Serviced Mortgage Loans) under each related Co-Lender Agreement and each applicable
Outside Servicing Agreement. The Master Servicer or Special Servicer, as applicable, (under the power of attorney granted by the
Trustee) shall take such actions as it shall deem reasonably necessary to facilitate the servicing of each Outside Serviced Companion
Loan by the related Outside Servicer and the related Outside Special Servicer, including, but not limited to, delivering appropriate
requests for release to the Custodian (if any) in order to deliver any portion of the related Mortgage Files to the related
Outside Servicer or related Outside Special Servicer under the applicable Outside Servicing Agreement.


 


To
the extent that the Trust, as holder of an Outside Serviced Mortgage Loan for the benefit of the Certificateholders, is entitled
to (i) consent to or approve any modification, waiver or amendment of such Outside Serviced Mortgage Loan or (ii) exercise any
consultation rights with respect to “Major Decisions” or “Material Actions” (as such term or any analogous
term is defined in the applicable Outside Servicing Agreement) in connection with such Outside Serviced Mortgage Loan or any related
REO Property or any consultation rights with respect to the implementation of “Asset Status Reports” (as such term
or any analogous term is defined in the applicable Outside Servicing Agreement), then the following party or parties (to the extent
notified by the appropriate party to the applicable Outside Servicing Agreement of any matter


 






    	-181- 



     


    

 


requiring the exercise of consent,
approval or consultation rights) shall actually exercise such consent, approval or consultation rights, and the respective parties
to this Agreement shall take such actions as are reasonably necessary to allow the following party or parties to exercise such
consent, approval or consultation rights: (a) the Controlling Class Representative (unless a Control Termination Event exists
or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan) or the Master Servicer (if a Control Termination Event exists
or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan) shall exercise any such consent or approval rights, in each
case in accordance with Section 3.01(i); and (b) the Controlling Class Representative (unless a Consultation Termination
Event exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan) or the Master Servicer (if a Consultation Termination
Event exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan) shall exercise any such consultation rights
entitled to be exercised by the holder of such Outside Serviced Mortgage Loan in accordance with Section 3.01(i); provided,
that after the occurrence and during the continuance of an Operating Advisor Consultation Trigger Event, any such consultation
rights shall be exercised by the Master Servicer or the Controlling Class Representative, as applicable, jointly with the Operating
Advisor (but, in the case of the Operating Advisor, only with respect to matters similar to Major Decisions). The Special Servicer
shall only be obligated to forward any requests received from the Outside Servicer or the Outside Special Servicer, as applicable,
for such consent and/or consultation to the Master Servicer (who shall forward any such request to the Controlling Class Representative
except if a Control Termination Event or Consultation Termination Event, as applicable, has occurred and is continuing or if such
Outside Serviced Mortgage Loan is an Excluded Mortgage Loan and, following the occurrence and during the continuance of an Operating
Advisor Consultation Trigger Event, to the Operating Advisor), and the Special Servicer shall have no right or obligation to exercise
any such consent or consultation rights.


 


In
addition to such consent, approval or consultation rights, the Controlling Class Representative (if no Control Termination Event
has occurred and is continuing and the related Outside Serviced Mortgage Loan is not an Excluded Mortgage Loan) and the Special
Servicer (if a Control Termination Event has occurred and is continuing), on behalf of the Trust, as holder of each Outside Serviced
Mortgage Loan for the benefit of the Certificateholders, will have the right (exercisable in its sole discretion), to the extent
provided in the related Co-Lender Agreement and/or the applicable Outside Servicing Agreement, to attend (in-person or telephonically)
annual meetings with the related Outside Servicer or Outside Special Servicer, as applicable, upon reasonable notice and at times
reasonably acceptable to the related Outside Servicer or Outside Special Servicer, as applicable, for the purpose of discussing
servicing issues related to such Outside Serviced Loan Combination.


 


None
of the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator, the Custodian or the Trustee
shall have any obligation or authority to supervise any Outside Servicer, any Outside Special Servicer, any Outside Trustee or
any other party to the applicable Outside Servicing Agreement or to make Property Advances with respect to any of the Outside
Serviced Mortgage Loans or a Companion Loan related to an Outside Serviced Mortgage Loan. The obligation of the Master Servicer
and the Special Servicer to provide information to the Trustee or any other Person with respect to the Outside Serviced Mortgage
Loans and any Outside Serviced Companion Loan related to an Outside Serviced Mortgage Loan is dependent on their receipt of the
corresponding information from the related Outside Servicer or the related Outside Special Servicer, as applicable.


 






    	-182- 



     


    

 


(h)         The
parties hereto acknowledge that each Outside Serviced Loan Combination is subject to the terms and conditions of the respective
Co-Lender Agreement and further acknowledge that, pursuant to the respective Co-Lender Agreement, (i) the related Outside
Serviced Mortgage Loan and the related Outside Serviced Companion Loans are to be serviced and administered by the related Outside
Servicer and Outside Special Servicer in accordance with the applicable Outside Servicing Agreement, and (ii) in the event
that the applicable Outside Serviced Companion Loan is no longer part of the trust fund created by the applicable Outside Servicing
Agreement and the related Outside Serviced Mortgage Loan remains an asset of the Trust Fund, then, as set forth in the related
Co-Lender Agreement, the related Outside Serviced Loan Combination shall be serviced in accordance with the applicable provisions
of the applicable Outside Servicing Agreement as if such agreement was still in full force and effect with respect to the related
Outside Serviced Loan Combination, until such time as a new servicing agreement has been agreed to by the parties to the related
Co-Lender Agreement in accordance with the provisions of such agreement and confirmation has been obtained from the Rating Agencies
that such new servicing agreement would not result in a downgrade, qualification or withdrawal of the then current ratings of
any Class of Certificates then outstanding and any other requirements applicable to the related Outside Serviced Mortgage Loan.


 


(i)          The
parties hereto acknowledge that each Outside Serviced Mortgage Loan is subject to the terms and conditions of the related Co-Lender
Agreement. With respect to each Outside Serviced Loan Combination, the parties hereto recognize the respective rights and obligations
of the related Outside Serviced Loan Combination Noteholders under the related Co-Lender Agreement, including with respect to
the allocation of collections and losses on or in respect of the related Outside Serviced Mortgage Loan and the related Outside
Serviced Companion Loan(s) and the making of payments to the related Outside Serviced Loan Combination Noteholders in accordance
with the related Co-Lender Agreement and the applicable Outside Servicing Agreement. The parties hereto further acknowledge that,
pursuant to the related Co-Lender Agreement, each Outside Serviced Mortgage Loan and the related Outside Serviced Companion Loan(s)
are to be serviced and administered by the related Outside Servicer and Outside Special Servicer in accordance with the applicable
Outside Servicing Agreement, and that payments allocated to each Outside Serviced Mortgage Loan and the related Outside Serviced
Companion Loans pursuant to the applicable Outside Servicing Agreement and the related Co-Lender Agreement are to be made by related
Outside Servicer. Although each Outside Serviced Mortgage Loan is not serviced and administered hereunder, the Master Servicer
and the Special Servicer hereunder for each such Outside Serviced Mortgage Loan shall have certain duties as set forth herein
and shall constitute the “Master Servicer” and “Special Servicer” hereunder with respect to each such
Outside Serviced Mortgage Loan.


 


If
there are at any time amounts due from the Trust, as holder of an Outside Serviced Mortgage Loan, to any party under the related
Co-Lender Agreement or the applicable Outside Servicing Agreement, the Master Servicer shall pay such amounts out of the Collection
Account. If a party to the applicable Outside Servicing Agreement related to an Outside Serviced Mortgage Loan requests the Master
Servicer, Special Servicer, Trustee, Certificate Administrator or Custodian to consent to, or consult with respect to, a modification,
waiver or amendment of, or other loan-level action related to, such Outside Serviced Mortgage Loan (except a modification, waiver
or amendment of the applicable Outside Servicing Agreement or the related Co-Lender Agreement which shall not be subject to the
operation of this sentence but shall instead be subject


 






    	-183- 



     


    

 


to the operation of the provisions below in this paragraph), the party
hereto that receives such request shall (but in the case of the Special Servicer subject to the limitation that it shall only
be required to deliver any such request to the Master Servicer) promptly deliver a copy of such request to the Controlling Class
Representative (if no Control Termination Event (in the case of consent rights) or Consultation Termination Event (in the case
of consultation rights) exists and such Outside Serviced Mortgage Loan is not an Excluded Mortgage Loan) or to the Master Servicer
(if a Control Termination Event (in the case of consent rights) or Consultation Termination Event (in the case of consultation
rights) exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan), as applicable, and, following the occurrence
and during the continuance of an Operating Advisor Consultation Trigger Event, to the Operating Advisor, and (a) any such consent
rights shall be exercised by the Controlling Class Representative (unless a Control Termination Event exists or such Outside Serviced
Mortgage Loan is an Excluded Mortgage Loan) or by the Master Servicer (if a Control Termination Event exists or such Outside Serviced
Mortgage Loan is an Excluded Mortgage Loan) and (b) any such consultation rights shall be exercised by the Controlling Class Representative
(unless a Consultation Termination Event exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan) or by the
Master Servicer (if a Consultation Termination Event exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan);
provided, that after the occurrence and during the continuance of an Operating Advisor Consultation Trigger Event, any
such consultation rights shall be exercised by the Master Servicer or the Controlling Class Representative, as applicable, jointly
with the Operating Advisor (but, in the case of the Operating Advisor, only with respect to matters similar to Major Decisions);
and provided, further, that, if such Outside Serviced Mortgage Loan were serviced hereunder and such action would
not be permitted without Rating Agency Confirmation, then the Controlling Class Representative or the Master Servicer, as applicable,
shall not exercise any such right of consent without first having obtained (or having caused the related Outside Servicer or Outside
Special Servicer to obtain) or received such Rating Agency Confirmation (payable at the expense of the party making such request
for consent or approval if such requesting party is a Certificateholder or a party to this Agreement, and otherwise from the Collection
Account). If a Responsible Officer of the Trustee, Certificate Administrator or Custodian receives actual notice of a termination
event under the applicable Outside Servicing Agreement, then the Trustee, Certificate Administrator or Custodian, as applicable,
shall notify the Master Servicer (in writing), and the Master Servicer shall act in accordance with the instructions of (prior
to the occurrence of a Control Termination Event) the Controlling Class Representative in accordance with the applicable Outside
Servicing Agreement with respect to such termination event (provided that the Master Servicer shall only be required to comply
with such instructions if such instructions are in accordance with the applicable Outside Servicing Agreement and not inconsistent
with this Agreement); provided that, if such instructions are not provided within a reasonable time period (not to exceed
ten (10) Business Days or such lesser response time as is afforded under the applicable Outside Servicing Agreement) or if a Control
Termination Event exists or if the Master Servicer is not permitted by the applicable Outside Servicing Agreement to follow such
instructions, then the Master Servicer shall take such action or inaction (to the extent permitted by the applicable Outside Servicing
Agreement), as directed in writing by the Holders of the Certificates evidencing at least 25% of the aggregate of all Voting Rights
(such direction to be sought and communicated to the Master Servicer by the Certificate Administrator) within a reasonable period
of time that does not exceed such response time as is afforded under the applicable Outside Servicing Agreement. Subject to the
foregoing, during the continuation of any termination event with respect to the related Outside Servicer or Outside Special Servicer
under


 






    	-184- 



     


    

 


the applicable Outside Servicing Agreement, each of the Trustee, the Certificate Administrator, the Master Servicer and
the Special Servicer shall have the right (but not the obligation) to take all actions to enforce its rights and remedies and
to protect the interests, and enforce the rights and remedies, of the Trust (including the institution and prosecution of all
judicial, administrative and other proceedings and the filings of proofs of claim and debt in connection therewith). The reasonable
costs and expenses incurred by the Master Servicer, Special Servicer, the Certificate Administrator, or the Trustee in connection
with such enforcement shall be paid by the Master Servicer out of the Collection Account. If the Trustee receives a request (and,
if the Master Servicer, Special Servicer or the Certificate Administrator receives such request, such party shall promptly forward
such request to the Trustee) from any party to the applicable Outside Servicing Agreement for consent to or approval of a modification,
waiver or amendment of the applicable Outside Servicing Agreement and/or the related Co-Lender Agreement, or the adoption of any
servicing agreement that is the successor to and/or in replacement of the applicable Outside Servicing Agreement in effect as
of the Closing Date or a change in servicer under the applicable Outside Servicing Agreement, then the Trustee is hereby directed
to, and the Trustee shall, grant such consent or approval if (a) the Trustee shall have received a prior Rating Agency Confirmation
from each Rating Agency (payable at the expense of the party making such request for consent or approval to the Trustee, if a
Certificateholder or a party to this Agreement, and otherwise from the Collection Account) with respect to such consent or approval,
and (b) unless a Control Termination Event has occurred and is continuing or the related Outside Serviced Mortgage Loan is an
Excluded Mortgage Loan, the Trustee shall have obtained the consent of the Controlling Class Representative. The Trustee, the
Certificate Administrator, the Special Servicer and the Master Servicer (each, a “Notifying Party”) shall each
promptly forward all material notices or other communications delivered to it in connection with the applicable Outside Servicing
Agreement to each other Notifying Party (unless a Notifying Party has actual knowledge that such other Notifying Party (i) was
copied on such original notice or communication or (ii) actually received such notice or communication), the Operating Advisor,
the Controlling Class Representative (if a Consultation Termination Event does not exist) and the Depositor and, if such notice
or communication is in the nature of a notice or communication that would be required to be delivered to the Rule 17g-5 Information
Provider (for posting to the Rule 17g-5 Information Provider’s Website in accordance with Section 12.13) if
the related Outside Serviced Mortgage Loan were a Mortgage Loan that is serviced and administered under this Agreement, to the
Rule 17g-5 Information Provider (who shall promptly post such notice to the Rule 17g-5 Information Provider’s Website in
accordance with Section 12.13); provided that, notwithstanding the foregoing, the Special Servicer shall have
no obligation to forward any such notice or communication under this provision unless (A) the Special Servicer is the only addressee
of such notice or communication or (B) there is no addressee on such notice or communication. Any obligation of the Master Servicer
or Special Servicer, as applicable, to provide information and collections to the Trustee, the Certificate Administrator, the
Controlling Class Representative and the Certificateholders with respect to any Outside Serviced Mortgage Loan shall be dependent
on its receipt of the corresponding information and collections from the related Outside Servicer or the related Outside Special
Servicer. Each of the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer shall reasonably cooperate
with the Master Servicer, the Special Servicer, the Operating Advisor or the Controlling Class Representative, in each case as
and when applicable, to facilitate the exercise by such party of any consent, approval or consultation rights set forth in this
Section 3.01 with respect to an Outside Serviced Mortgage Loan; provided, however, the Trustee, the Certificate
Administrator, the Master Servicer and the Special Servicer


 






    	-185- 



     


    

 


shall have no right or obligation to exercise any consent or consultation
rights or obtain a Rating Agency Confirmation on behalf of the Controlling Class Representative.


 


(j)          With
respect to each Outside Serviced Mortgage Loan, the parties to this Agreement agree as follows:


 


(i)          pursuant
to the related Outside Servicing Agreement, the related Outside Servicer or Outside Special Servicer, as applicable, is obligated
to make “Servicing Advances” or “Property Advances” and incur “Additional Trust Fund Expenses”
(as each such term or any analogous term is defined in the related Outside Servicing Agreement) with respect to such Outside Serviced
Mortgage Loan; the Trust shall be responsible for its pro rata share (such pro rata share and the pro rata
share of the holder(s) of the related Outside Serviced Companion Loan(s) to be determined based on the respective principal balances
of such Outside Serviced Mortgage Loan and the related Outside Serviced Companion Loan(s)) of any “Nonrecoverable Servicing
Advance” or “Nonrecoverable Property Advances” (and advance interest thereon) and any “Additional Trust
Fund Expenses” (as each such term or any analogous term is defined in the related Outside Servicing Agreement), but only
to the extent that they relate to servicing and administration of such Outside Serviced Mortgage Loan, including without limitation,
any unpaid “Special Servicing Fees,” “Liquidation Fees” and “Workout Fees” (as each such term
or any analogous term is defined in the related Outside Servicing Agreement) relating to such Outside Serviced Mortgage Loan;
and in the event that the funds received with respect to the related Outside Serviced Loan Combination are insufficient to cover
“Servicing Advances,” “Property Advances” or “Additional Trust Fund Expenses” (as each such

of the related Outside Serviced Loan Combination, (i) the Master Servicer shall, promptly following notice from the related
Outside Servicer, reimburse the related Outside Servicer, the related Outside Special Servicer, the related Outside Certificate
Administrator or the related Outside Trustee, as applicable (such reimbursement, to the extent owed to the related Outside Special
Servicer, the related Outside Certificate Administrator or the related Outside Trustee, may be paid by the Master Servicer to
the related Outside Servicer, who shall pay such amounts to the related Outside Special Servicer, the related Outside Certificate
Administrator or the related Outside Trustee, as applicable), out of general funds in the Collection Account for the Trust’s
pro rata share (such pro rata share and the pro rata share of the holder(s) of the related Outside Serviced
Companion Loan(s) to be determined based on the respective principal balances of such Outside Serviced Mortgage Loan and the related
Outside Serviced Companion Loan(s)) of any such “Nonrecoverable Servicing Advance,” “Nonrecoverable Property
Advances” and/or “Additional Trust Fund Expenses” (as each such term or any analogous term is defined in the
applicable Outside Servicing Agreement), and (ii) if the related Outside Servicing Agreement permits the related Outside
Servicer, the related Outside Special Servicer, the related Outside Certificate Administrator or the related Outside Trustee to
reimburse itself from the related Outside Securitization Trust’s general account, then the parties to this Agreement hereby
acknowledge and agree that the related Outside Servicer, the related Outside Special Servicer, the related Outside Certificate
Administrator or the related Outside Trustee, as applicable, may do so and the Master Servicer shall be required to, promptly
following notice from the related Outside Servicer, reimburse the


 






    	-186- 



     


    

 


related Outside Securitization Trust out of general funds in
the Collection Account for the Trust’s pro rata share (such pro rata share and the pro rata share of
the holder(s) of the related Outside Serviced Companion Loan(s) to be determined based on the respective principal balances of
such Outside Serviced Mortgage Loan and the related Outside Serviced Companion Loan(s)) of any such “Nonrecoverable Servicing
Advance,” “Nonrecoverable Property Advances” and/or “Additional Trust Fund Expenses” (as each such
term or any analogous term is defined in the applicable Outside Servicing Agreement) relating to the servicing and administration
of such Outside Serviced Loan Combination;


 


(ii)         With
respect to each Outside Serviced Mortgage Loan, each of (i) (as and to the same extent the related Outside Securitization Trust

other mortgage loans in the related Outside Securitization Trust pursuant to the terms of the related Outside Servicing Agreement)
the related Outside Servicer, the related Outside Special Servicer, the related Outside Certificate Administrator, the related

or agent of any of the foregoing, to the extent such parties are identified as “Indemnified Parties” in the related
Outside Servicing Agreement in respect of other mortgages included in such Outside Securitization Trust) and (ii) the related
Outside Securitization Trust (such parties in clause (i) and the related Outside Securitization Trust, collectively, the “Pari
Passu Indemnified Parties”) shall be indemnified against any claims, losses, penalties, fines, forfeitures, legal fees
and related costs, judgments and any other costs, liabilities, fees and expenses incurred in connection with the servicing and
administration of such Outside Serviced Mortgage Loan and the related Mortgaged Property (or, with respect to the related Outside
Operating Advisor, incurred in connection with the provision of services for such Outside Serviced Mortgage Loan) under the applicable
Outside Servicing Agreement (collectively, the “Pari Passu Indemnified Items”) to the extent of the Trust’s
pro rata share (such pro rata share and the pro rata share of the holder(s) of the related Outside Serviced
Companion Loan(s) to be determined based on the respective principal balances of such Outside Serviced Mortgage Loan and the related
Outside Serviced Companion Loan(s)) of such Pari Passu Indemnified Items, and to the extent amounts on deposit in the “Serviced
Loan Combination Collection Account”, “Serviced Pari Passu Companion Loan Custodial Account”, “Whole Loan

the extent not otherwise expressly included herein, any provisions required to be included herein pursuant to any Co-Lender Agreement
for an Outside Serviced Loan Combination are deemed incorporated herein by reference, and the parties hereto shall comply with
those provisions as if set forth herein in full. In the event of any inconsistency between the provisions of this Agreement and
any Outside Serviced Co-Lender Agreement, such Outside Serviced Co-Lender Agreement shall prevail, provided that in no event shall
the Master Servicer or the Special Servicer, as the case may be, take


 






    	-187- 



     


    

 


any action or omit to take any action in accordance with
the terms of any Outside Serviced Co-Lender Agreement, that would cause the Master Servicer or the Special Servicer, as the case
may be, to violate the Servicing Standard or REMIC Provisions; and


 


(iv)        each
Outside Servicer, each Outside Special Servicer, each Outside Certificate Administrator, each Outside Trustee, each Outside Operating
Advisor and each Outside Securitization Trust shall be third party beneficiaries of this Section 3.01(j).


 


(k)         To
the extent required under any Loan Documents, the Master Servicer shall, on behalf of the related lender, maintain a Note register
for the related Mortgage Loan in accordance with such Loan Documents.


 


(l)          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 (for the purposes of this clause (l), “Applicable
Laws”), the Master Servicer may be required to obtain, verify and record certain information relating to individuals
and entities which maintain a business relationship with the Master Servicer. Accordingly, each of the parties hereto agrees to
provide to the Master Servicer, upon its reasonable request, from time to time such identifying information and documentation
as may be readily available to such party in order to enable the Master Servicer to comply with Applicable Laws; provided that
the Master Servicer shall be responsible for all reasonable actual out-of-pocket expenses incurred by such party in connection
therewith.


 


Section 3.02           Liability
of the Master Servicer. Notwithstanding any Sub-Servicing Agreement or primary servicing agreement, any of the
provisions of this Agreement relating to agreements or arrangements between the Master Servicer and any Person acting as
Sub-Servicer (or its agents or subcontractors) or any reference to actions taken through any Person acting as Sub-Servicer or
otherwise, the Master Servicer shall remain obligated and primarily liable to the Trustee, the Certificate Administrator, the
Certificateholders and any Serviced Companion Loan Holder for the servicing and administering of the Mortgage Loans (other
than the Outside Serviced Mortgage Loans) and the Serviced Companion Loan in accordance with the provisions of this Agreement
without diminution of such obligation or liability by virtue of such Sub-Servicing Agreements, primary servicing agreements
or arrangements or by virtue of indemnification from any Person acting as Sub-Servicer (or its agents or subcontractors) to
the same extent and under the same terms and conditions as if the Master Servicer alone was servicing and administering the
Mortgage Loans (other than the Outside Serviced Mortgage Loans) and the Serviced Companion Loan. The Master Servicer shall be
entitled to enter into an agreement with any Sub-Servicer providing for indemnification of the Master Servicer by such
Sub-Servicer, and nothing contained in this Agreement shall be deemed to limit or modify such indemnification, but no such
agreement for indemnification shall be deemed to limit or modify this Agreement.


 


Section 3.03           Collection
of Certain Mortgage Loan Payments. 


 


(a)          The Master
Servicer (with respect to Performing Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans),
as applicable, shall use reasonable efforts in accordance with the Servicing Standard to collect all payments called for
under the terms and provisions of the Serviced Loans it is obligated to service hereunder, and shall follow the Servicing
Standard with respect to such collection procedures; provided that, with respect to any


 






    	-188- 



     


    

 


ARD
Mortgage Loan, so long as the related Mortgagor is in compliance with each provision of the related Loan Documents, the
Master Servicer and the Special Servicer shall not take any enforcement action with respect to the failure of the related
Mortgagor to make any payment of Excess Interest, other than requests for collection, until the Maturity Date of any ARD
Mortgage Loan or until the outstanding principal balance of such ARD Mortgage Loan (exclusive of any portion representing
accrued Excess Interest) has been paid in full); provided, further, that, with respect to any ARD Mortgage
Loan, the Master Servicer or Special Servicer, as the case may be, may take action to enforce the Trust Fund’s right to
apply excess cash flow to principal in accordance with the terms of the Loan Documents. For clarification, no obligation of
the Master Servicer or the Special Servicer to use reasonable efforts to collect fees from the related Mortgagor will change
the obligation of the Master Servicer to pay such fees from general collections or other proceeds in accordance
with Section 3.06(a) and Section 3.06A(a) of this Agreement, whether or not such Special Servicing
Fees, Workout Fees or Liquidation Fees are collected from or paid by the related Mortgagor. The Master Servicer, with respect
to the Performing Serviced Loans, and the Special Servicer, with respect to the Specially Serviced Loans, shall use its
reasonable efforts to collect income statements, rent rolls and other reporting information from Mortgagors (as required
under the related Loan Documents). Consistent with the foregoing, the Master Servicer (with respect to Performing Serviced
Loans) or Special Servicer (with respect to Specially Serviced Loans), as applicable, may in its discretion waive any Penalty
Charges in connection with any delinquent Monthly Payment with respect to any Mortgage Loan (other than an Outside Serviced
Mortgage Loan) or Serviced Companion Loan. In addition, the Master Servicer shall be entitled to take such actions with
respect to the collection of payments on the Mortgage Loans (other than the Outside Serviced Mortgage Loans) and the Serviced
Companion Loan as are permitted or required under Section 3.21 of this Agreement.


 


(b)         If
the Master Servicer receives Excess Interest directly from the related Mortgagor or through the Special Servicer, which Excess
Interest was collected during the Collection Period for any Distribution Date, or receives notice from the related Mortgagor that
the Master Servicer will be receiving Excess Interest during the Collection Period for any Distribution Date, then the Master
Servicer shall notify the Certificate Administrator no later than two Business Days prior to such Distribution Date by means of
a clearly labeled item in the CREFC® Loan Periodic Update File. None of the Master Servicer, the Special Servicer,
the Certificate Administrator or the Trustee shall be responsible for any failure of the related Mortgagor to pay any such Excess
Interest. The preceding statements shall not, however, be construed to limit the provisions of Section 3.03(a) of this
Agreement.


 


(c)         With
respect to each Outside Serviced Mortgage Loan, the Certificate Administrator shall deliver to the related Outside Trustee, the
related Outside Certificate Administrator, the related Outside Special Servicer, the related Outside Servicer and the related
Outside Operating Advisor promptly following the Closing Date (and, in the case of each Servicing Shift Mortgage Loan, promptly
upon the related Servicing Shift Date and, in the case of the 50 Varick Street Mortgage Loan, also promptly upon the Certificate
Administrator’s receipt of notice of the 50 Varick Street Controlling Pari Passu Companion Loan Securitization Date), written
notice in the form of Exhibit FF-1, Exhibit FF-2, Exhibit FF-3, Exhibit FF-4, Exhibit FF-5,
Exhibit FF-6, Exhibit FF-7 and Exhibit FF-8 attached hereto, as applicable, stating that, as of the Closing

amounts payable to, and to forward, deliver or otherwise make
available, as the case may be, to the Master Servicer all reports, statements, documents, communications and other information
that are to be forwarded, delivered or otherwise made available to, the holder of such Outside Serviced Mortgage Loan under the
related Co-Lender Agreement and the applicable Outside Servicing Agreement (which notice shall also provide contact information
for the Trustee, the Certificate Administrator, the Master Servicer, the Special Servicer and each party designated to exercise
the rights of the “Non-Controlling Note Holder” under the related Co-Lender Agreement), accompanied by a copy of an
executed version of this Agreement, and (B) notice of any subsequent change in the identity of the Master Servicer or any
party designated to exercise the rights of the “Non-Controlling Note Holder” under the related Co-Lender Agreement
(together with the relevant contact information). The Master Servicer shall, within one (1) Business Day of receipt of properly
identified funds, deposit into the Collection Account all amounts received with respect to each Outside Serviced Mortgage Loan,
the Mortgaged Property related to each Outside Serviced Mortgage Loan or any related REO Property; provided, however,
that to the extent any such amounts are received after 2:00 p.m. Eastern time on any given Business Day, the Master Servicer shall
use commercially reasonable efforts to deposit such amounts into the Collection Account within one (1) Business Day of receipt
of such amounts but, in any event, the Master Servicer shall deposit such amounts into the Collection Account within two (2) Business
Days of receipt of such amounts.


 


(d)         With
respect to each Outside Serviced Mortgage Loan, if the Master Servicer does not receive from the related Outside Servicer any
Monthly Payment or other amounts known by the Master Servicer to be owing on such Outside Serviced Mortgage Loan in accordance
with the terms of the applicable Outside Servicing Agreement and/or the related Co-Lender Agreement, then the Master Servicer
shall provide notice of such failure to the related Outside Servicer and the related Outside Trustee.


 


Section 3.04           Collection
of Taxes, Assessments and Similar Items; Escrow Accounts.


 


(a)          With
respect to each Mortgaged Property securing a Serviced Loan, the Master Servicer shall maintain accurate records with
respect to each related Mortgaged Property reflecting the status of taxes, assessments, ground rents and other similar items
that are or may become a lien on the related Mortgaged Property and the status of insurance premiums payable with respect
thereto. From time to time, to the extent such payments are to be made from escrowed funds, the Master Servicer shall
(i) obtain all bills for the payment of such items (including renewal premiums), and (ii) effect payment of all
such bills with respect to such Mortgaged Properties prior to the applicable penalty or termination date, in each case
employing for such purpose Escrow Payments as allowed under the terms of the related Serviced Loan. With respect to
non-escrowed payments, when the Master Servicer becomes aware in accordance with the Servicing Standard that a
Mortgagor (other than with respect to the Outside Serviced Mortgage Loan) has failed to make any such payment or, with
respect to escrowed loans, collections from the Mortgagor are insufficient to pay any such item before the applicable penalty
or termination date, the Master Servicer shall advance the amount of any shortfall as a Property Advance unless the Master
Servicer determines in accordance with the Servicing Standard that such Advance would be a Nonrecoverable Advance.
Notwithstanding anything in this Agreement to the contrary, the Master Servicer may in accordance with the Servicing Standard
elect (but is not required) to make (and in


 






    	-190- 



     


    

 


the case of a Specially Serviced Loan, at the direction of the Special Servicer
will be required to make) a payment from amounts on deposit in the Collection Account that would otherwise be a Property
Advance with respect to a Mortgage Loan (other than an Outside Serviced Mortgage Loan) notwithstanding that the Master
Servicer or the Special Servicer has determined that such a Property Advance would, if advanced, be a Nonrecoverable
Property Advance, if making the payment (x) would prevent (i) the related Mortgaged Property from being uninsured
or being sold at a tax sale or (ii) any event that would cause a loss of the priority of the lien of the related
Mortgage, or the loss of any security for the related Mortgage Loan, or (y) would remediate any adverse environmental
condition or circumstance at the related Mortgaged Property, if, in each instance, the Master Servicer or the Special
Servicer, as applicable, determines in accordance with the Servicing Standard that making the payment is in the best interest
of the Certificateholders and any related Serviced Companion Loan Holder(s) (as a collective whole as if the
Certificateholders and such Serviced Companion Loan Holder(s) constituted a single lender (and, in the case of a Serviced AB
Loan Combination, taking into account the subordinate nature of the related Subordinate Companion Loan(s))). If the Special
Servicer makes such a determination, it shall notify the Master Servicer and the Master Servicer shall make such payment from
the Collection Account. No costs incurred by the Master Servicer in effecting the payment of taxes and assessments on the
Mortgaged Properties shall, for the purpose of calculating distributions to Certificateholders, be added to the amount owing
under the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.


 


(b)         The
Master Servicer shall segregate and hold all funds collected and received pursuant to any Mortgage Loan or Serviced Loan
Combination constituting Escrow Payments separate and apart from any of its own funds and general assets and shall establish
and maintain one or more segregated custodial accounts (each, an “Escrow Account”) into which all Escrow
Payments shall be deposited within two (2) Business Days after receipt of properly identified funds. The Master Servicer
shall also deposit into each applicable Escrow Account any amounts representing losses on Permitted Investments to the extent
required by Section 3.07(b) of this Agreement and any Insurance Proceeds or Condemnation Proceeds which are
required to be applied to the restoration or repair of any Mortgaged Property pursuant to the related Mortgage Loan. Escrow
Accounts shall be Eligible Accounts (except to the extent the related Mortgage Loan requires or permits it to be held in an
account that is not an Eligible Account) in accordance with the terms of the related Loan Documents) and (subject to any
changes in the identities of the Master Servicer and/or the Trustee) shall be entitled, “Midland Loan Services, a
Division of PNC Bank, National Association, as Master Servicer, on behalf of Wilmington Trust, National Association, as
Trustee for the benefit of the registered Holders of Citigroup Commercial Mortgage Trust 2017-C4, Commercial Mortgage
Pass-Through Certificates, Series 2017-C4, the Serviced Companion Loan Holders, and Various Mortgagors.” Withdrawals
from an Escrow Account may be made by the Master Servicer only:


 


(i)          to
effect timely payments of items constituting Escrow Payments for the related Loan Documents and in accordance with the terms of
the related Mortgage Loan or Serviced Loan Combination, as applicable;


 


(ii)         to
transfer funds to the Collection Account and/or the applicable Loan Combination Custodial Account to reimburse the Master Servicer,
the Special Servicer or the Trustee, as applicable, for any Property Advance (with interest thereon at the Advance


 






    	-191- 



     


    

 


Rate) relating
to Escrow Payments, but only from amounts received with respect to the related Mortgage Loan or Serviced Loan Combination, as
applicable, which represent late collections of Escrow Payments thereunder;


 


(iii)        for
application to the restoration or repair of the related Mortgaged Property in accordance with the related Mortgage Loan or Serviced
Loan Combination, as applicable, and the Servicing Standard;


 


(iv)        to
clear and terminate such Escrow Account upon the termination of this Agreement;


 


(v)         to
pay from time to time to the related Mortgagor (a) any interest or investment income earned on funds deposited in the Escrow
Account if such income is required to be paid to the related Mortgagor under law or by the terms of the Mortgage Loan or Serviced
Loan Combination, as applicable, or otherwise to the Master Servicer and (b) any other funds required to be released to the
related Mortgagors pursuant to the related Loan Documents; and


 


(vi)        to
remove any funds deposited in an Escrow Account that were not required to be deposited therein.


 


(c)         In
the event any Loan Documents permit the lender, at the discretion of the lender, to use letters of credit and/or cash reserves
to prepay the related Mortgage Loan prior to the Maturity Date and in the absence of an event of default or acceleration of the
Mortgage Loan, then the Master Servicer shall hold such amounts in an Escrow Account for so long as the Loan Documents permit
such discretion.


 


(d)          Unless
required by the related Loan Documents, neither the Master Servicer nor the Special Servicer shall apply any earnout escrows or
reserves established with respect to any Mortgage Loan as a prepayment of such Mortgage Loan if no event of default has occurred
under such Mortgage Loan.


 


(e)          To
the extent that (i) an operations and maintenance plan is required to be established and executed pursuant to the terms of
a Serviced Loan, or (ii) any repairs, capital improvements, actions or remediations are required to have been taken or completed
pursuant to the terms of the Serviced Loan, the Master Servicer shall determine in accordance with the Servicing Standard (which
determination may be made on the basis of inquiry to the Mortgagor and this sentence shall in no event be construed to require
a physical inspection other than inspections described in Section 3.18 of this Agreement; provided that all
deliveries required to be made to Master Servicer under the related Loan Documents of supporting documentation have been made;
then the Master Servicer shall report the then current status as a failure) whether the related Mortgagor has failed to perform
such obligations under the related Mortgage Loan or Serviced Loan Combination as of the date required under the related Mortgage
Loan or Serviced Loan Combination and report any such failure to the Special Servicer, the Serviced Companion Loan Holders and,
prior to the occurrence and continuance of a Consultation Termination Event, the Controlling Class Representative within a reasonable
time after the date as of which such actions or remediations are required to be or to have been taken or completed.

Section 3.05           Collection
Account; Distribution Accounts; and Excess Liquidation Proceeds Reserve Account; and Excess Interest Distribution Account.


 


(a)          The
Master Servicer shall establish and maintain the Collection Account in the Master Servicer’s name on behalf of the Trustee,
for the benefit of the Certificateholders and the Trustee as the Holder of the Lower-Tier Regular Interests. The Collection Account
shall be established and maintained as an Eligible Account. Amounts attributable to the Mortgage Loans (other than the Excess
Interest) will be assets of the Lower Tier REMIC. As and when required under this Agreement, the Master Servicer shall transfer
to the Collection Account any amounts to be transferred thereto from a Loan Combination Custodial Account as contemplated by Section 3.06A(a)(i)
of this Agreement, and the Master Servicer shall deposit in the Collection Account any amounts required to be deposited therein
pursuant to Section 3.07(b) of this Agreement in connection with net losses realized on Permitted Investments with
respect to funds held in the Collection Account. In addition, the Master Servicer shall deposit or cause to be deposited in the
Collection Account, within one (1) Business Day following receipt of properly identified funds, (x) all Net Liquidation Proceeds
received on or with respect to a Mortgage Loan related to a Serviced Loan Combination in connection with any of the events described
in clauses (iii) and (iv) of the definition of “Liquidation Event” in this Agreement, and (y) without
duplication, the following payments and collections received or made by it on or with respect to the Mortgage Loans (other than
any Mortgage Loan related to a Serviced Loan Combination):


 


(i)          all
payments on account of principal on such Mortgage Loans, including Principal Prepayments and the principal component of Insurance
Proceeds, Condemnation Proceeds and Liquidation Proceeds;


 


(ii)         all
payments on account of interest on such Mortgage Loans (including Excess Interest);


 


(iii)        all
Yield Maintenance Charges on such Mortgage Loans;


 


(iv)        all
amounts with respect to any related REO Property transferred to the Collection Account, or to the Master Servicer for deposit
in the Collection Account, from an REO Account pursuant to Section 3.16(b) of this Agreement;


 


(v)         all
Net Insurance Proceeds, Net Condemnation and Net Liquidation Proceeds with respect to such Mortgage Loans;


 


(vi)        any
amounts received from Mortgagors under such Mortgage Loans that represent (A) recoveries of Property Protection Expenses,
(B) any recovery of Unliquidated Advances with respect to such Mortgage Loans, or (C) any other reimbursements in accordance
with the related Loan Documents, in each case to the extent not permitted to be retained by the Master Servicer as provided herein;


 


(vii)       any
Loss of Value Payments, as set forth in Section 3.06(c) of this Agreement;


 


(viii)      with
respect to the Mortgage Loan secured by the Mortgaged Property identified on the Mortgage Loan Schedule as “Station Place
III”, any Initial Month’s


 






    	-193- 



     


    

 


Interest Deposit Amount remitted by the related Mortgage Loan Seller to the Master Servicer
pursuant to Section 1 of the related Loan Purchase Agreement; and


 


(ix)        any
other amounts required by the provisions of this Agreement to be deposited into the Collection Account by the Master Servicer
or Special Servicer, including pursuant to Section 2.03 and Section 3.03(c) of this Agreement;


 


provided, however,
that to the extent any amounts referred to in clauses (x) or (y) above of this Section 3.05(a) are
received after 2:00 p.m. Eastern time on any given Business Day, the Master Servicer shall use commercially
reasonable efforts to deposit such amounts into the Collection Account within one (1) Business Day of receipt thereof but, in
any event, the Master Servicer shall deposit such amounts into the Collection Account within two (2) Business Days of receipt
thereof.


 


The
foregoing requirements for deposits in the Collection Account shall be exclusive, it being understood and agreed that, without
limiting the generality of the foregoing, to the extent provided herein, Ancillary Fees, Consent Fees, Assumption Fees, assumption
application fees, defeasance fees, review fees and other amounts that constitute other Additional Servicing Compensation or other
Additional Special Servicing Compensation need not be deposited in the Collection Account by the Master Servicer or the Special
Servicer, as applicable, and, to the extent permitted by applicable law, the Master Servicer or the Special Servicer, as applicable,
shall be entitled to retain any such Ancillary Fees, Consent Fees, Assumption Fees, assumption application fees, defeasance fees,
review fees and/or amounts that constitute other Additional Servicing Compensation or other Additional Special Servicing Compensation
received with respect to such Mortgage Loans in accordance with Section 3.12 of this Agreement; provided that if the Master
Servicer or the Special Servicer, as applicable, receives any such Ancillary Fees, Consent Fees, Assumption Fees, assumption application
fees, defeasance fees and/or amounts that constitute other Additional Servicing Compensation or other Additional Special Servicing
Compensation in excess of the percentage of such fees to which it is entitled pursuant to Section 3.12(a) (in the case
of the Master Servicer) or Section 3.12(c) (in the case of the Special Servicer), then it shall remit to the other party
(i.e. the Special Servicer (if Master Servicer has received the excess percentage of such fees) or the Master Servicer (if Special
Servicer has received the excess percentage of such fees), as applicable) the percentage of such fees to which such other party
is entitled pursuant to Section 3.12(a) or Section 3.12(c), as applicable. To the extent that any Penalty Charges
or Modification Fees received by the Master Servicer or the Special Servicer, as applicable, with respect to any Mortgage Loan
constitute servicing compensation pursuant to Section 3.14(a)(iv) of this Agreement, the Master Servicer and the Special
Servicer shall not deposit such fees into the Collection Account and shall instead apply such fees in accordance with Section
3.14(a)(iv) of this Agreement. In the event that the Master Servicer deposits in the Collection Account any amount not required
to be deposited therein, it may at any time withdraw such amount from the Collection Account, any provision herein to the contrary
notwithstanding. The Master Servicer shall give written notice to the Certificate Administrator and the Special Servicer of the
location and account number of the Collection Account and shall notify the Certificate Administrator and the Special Servicer
in writing of any subsequent change thereof.


 


Upon
receipt of any of the amounts described in clauses (i) through (vi) and (ix) of the last sentence of the second preceding
paragraph with respect to a Mortgage Loan (other than a Mortgage Loan related to a Serviced Loan Combination), the Special Servicer
shall promptly, but


 






    	-194- 



     


    

 


in no event later than one (1) Business Day after receipt of properly identified funds, remit such amounts
to the Master Servicer for deposit into the Collection Account in accordance with the second preceding paragraph, unless the Special
Servicer determines, consistent with the Servicing Standard, that a particular item should not be deposited because of a restrictive
endorsement or other appropriate reason. With respect to any such amounts paid by check to the order of the Special Servicer,
the Special Servicer shall endorse such check to the order of the Master Servicer, unless the Special Servicer determines, consistent
with the Servicing Standard, that a particular item cannot be so endorsed and delivered because of a restrictive endorsement or
other appropriate reason. Any such amounts received by the Special Servicer with respect to an REO Property that relates to any
Mortgage Loan (other than a Mortgage Loan related to a Serviced Loan Combination) shall initially be deposited by the Special
Servicer into the related REO Account (or, at the option of the Special Servicer, remitted by the applicable property manager
directly to the Master Servicer) and thereafter remitted to the Master Servicer for deposit into the Collection Account, all in
accordance with Section 3.16 of this Agreement.


 


(b)         The
Certificate Administrator shall establish and maintain the Lower-Tier REMIC Distribution Account and the Upper-Tier REMIC Distribution
Account in the name of the Certificate Administrator on behalf of the Trustee, for the benefit of the Certificateholders. Each
of the Distribution Accounts shall be non-interest bearing and shall be established and maintained as Eligible Accounts or as
sub-accounts of a single Eligible Account. With respect to each Distribution Date, on or before such Distribution Date, the Certificate
Administrator shall be deemed to make or shall make the withdrawals from the Lower-Tier REMIC Distribution Account, as set forth
in Section 4.01 of this Agreement, shall be deemed to make the deposits into the Lower-Tier REMIC Distribution Account
and the Upper-Tier REMIC Distribution Account, as set forth in Section 4.01 hereof, and shall cause the amount of
Available Funds (including P&I Advances) and Yield Maintenance Charges to be distributed in respect of the Certificates, pursuant
to Section 4.01 hereof on such date.


 


(c)         The
Certificate Administrator shall establish (upon receipt of written notice that an event that generates Excess Liquidation Proceeds
has occurred) and maintain the Excess Liquidation Proceeds Reserve Account in the name of the Certificate Administrator on behalf
of the Trustee for the benefit of the Certificateholders. The Excess Liquidation Proceeds Reserve Account shall be non-interest
bearing and shall be maintained separate and apart from trust funds for mortgage pass-through certificates of other series administered
by the Certificate Administrator and other accounts of the Certificate Administrator.


 


Upon
the disposition of any REO Property in accordance with Section 3.17 of this Agreement, the Special Servicer shall
calculate the Excess Liquidation Proceeds, if any, realized in connection with such sale and remit to the Certificate Administrator
such amount for deposit in the Excess Liquidation Proceeds Reserve Account. Amounts held in the Excess Liquidation Proceeds Reserve
Account on each Distribution Date that exceed amounts reasonably anticipated to be required to offset possible future Realized
Losses, as determined by the Special Servicer, and all amounts held in the Excess Liquidation Proceeds Reserve Account on the
final Distribution Date, in each case after application in accordance with Section 4.01(d)(i) of this Agreement, shall
be distributed to the Holders of the Class R Certificates in respect of the Lower-Tier Residual Interest.





 






    	-195- 



     


    

 


(d)         [RESERVED]


 


(e)         Prior
to the Master Servicer Remittance Date immediately following the end of the first Collection Period during which Excess Interest
is received on any ARD Mortgage Loan, and upon notification from the Master Servicer pursuant to Section 3.03(b) of this
Agreement, the Certificate Administrator shall establish and maintain the Excess Interest Distribution Account in the name of
the Certificate Administrator on behalf of the Trustee, for the benefit of the Holders of the Excess Interest Certificates. The
Excess Interest Distribution Account shall be non-interest bearing and shall be established and maintained as an Eligible Account
(or as a subaccount of an Eligible Account). With respect to each Distribution Date, the Master Servicer shall withdraw from the
Collection Account and remit to the Certificate Administrator on the applicable Master Servicer Remittance Date for deposit in
the Excess Interest Distribution Account an amount equal to the Excess Interest received during the applicable Collection Period.


 


The
Certificate Administrator shall, on any Distribution Date, make withdrawals from the Excess Interest Distribution Account to the
extent required to make the distributions of Excess Interest required by Section 4.01(j) of this Agreement.


 


Following
the distribution of Excess Interest to the Holders of the Excess Interest Certificates on the first Distribution Date after which
there are no longer any ARD Mortgage Loans outstanding, the Certificate Administrator may terminate the Excess Interest Distribution
Account.


 


(f)          Notwithstanding
anything to the contrary herein, the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Excess
Interest Distribution Account, the Excess Liquidation Proceeds Reserve Account and the Interest Reserve Account may all be sub-accounts
of a single Eligible Account; provided that each of them shall be treated as a separate account for purposes of deposits and withdrawals
under this Agreement.


 


(g)         If
any Loss of Value Payments are received in connection with a Material Document Defect or Material Breach, as the case may be,
pursuant to or as contemplated by Section 2.03(a) of this Agreement, the Special Servicer shall establish and maintain
one or more accounts (collectively, the “Loss of Value Reserve Fund”) to be held on behalf of the Trustee for
the benefit of the Certificateholders, for purposes of holding such Loss of Value Payments. Each account that constitutes the
Loss of Value Reserve Fund shall be an Eligible Account or a sub-account of an Eligible Account. The Special Servicer shall, upon
receipt, deposit in the Loss of Value Reserve Fund all Loss of Value Payments received by it. The Loss of Value Reserve Fund shall
be accounted for as an outside reserve fund within the meaning of Treasury Regulations Section 1.860G-2(h) and not an asset of
any Trust REMIC. Furthermore, for all federal tax purposes, the Certificate Administrator shall (i) treat amounts paid out of
the Loss of Value Reserve Fund (and any income earned thereon) through the Collection Account to the Certificateholders (or, in
the case of any income earned on the Loss of Value Reserve Fund and paid to the Special Servicer as additional compensation) as
damages paid to and distributed by the Trust REMICs on account of a breach of a representation or warranty by the related Mortgage
Loan Seller and (ii) treat any amounts paid out of the Loss of Value Reserve Fund through the Collection Account to a Mortgage
Loan Seller as distributions by the Trust Fund to such Mortgage Loan Seller as beneficial owner of the Loss of Value Reserve Fund.
The applicable Mortgage


 






    	-196- 



     


    

 


Loan Seller will be the beneficial owner of the related account in the Loss of Value Reserve Fund for
all federal income tax purposes, and shall be taxable on all income earned thereon.


 


(h)         For
the avoidance of doubt, the Lower-Tier REMIC Distribution Account, the Excess Liquidation Proceeds Reserve Account, and the Interest
Reserve Account (including interest, if any, earned on the investment of funds in such accounts) will be owned by the Lower-Tier
REMIC, the Excess Interest Distribution Account will be owned by the Grantor Trust, and the Upper-Tier REMIC Distribution Account
(including interest, if any, earned on the investment of funds in such account) will be owned by the Upper-Tier REMIC, each for
federal income tax purposes.


 


Section 3.05A.     Loan Combination Custodial Account.


 


(a)         The
Master Servicer shall establish and maintain, with respect to each Serviced Loan Combination (if any), one or more separate accounts,
which may be sub-accounts of a single account (with respect to each Serviced Loan Combination, the “Loan Combination
Custodial Account”) in which the amounts described in clauses (i) through (viii) below shall be deposited
and held in the name of the Master Servicer on behalf of the Trustee for the benefit of the Certificateholders and the related
Serviced Companion Loan Holder, as their interests may appear; provided that a Loan Combination Custodial Account may be
a sub-account of the Collection Account or another Loan Combination Custodial Account (but shall be deemed to be a separate account
for purposes of applying the terms of this Agreement). Each of the Loan Combination Custodial Accounts shall be an Eligible Account
or a subaccount of an Eligible Account. The Master Servicer shall deposit or cause to be deposited in each Loan Combination Custodial
Account, within one Business Day following receipt of properly identified funds (or, in the case of payments by the Master Servicer,
when otherwise required to be so deposited under this Agreement), the following payments and collections received or made by it
on or with respect to the related Serviced Loan Combination:


 


(i)          all
payments on account of principal on the related Serviced Loan Combination, including Principal Prepayments and the principal component
of Insurance Proceeds, Condemnation Proceeds and Liquidation Proceeds;


 


(ii)         all
payments on account of interest on the related Serviced Loan Combination;


 


(iii)        all
Yield Maintenance Charges on the related Serviced Loan Combination;


 


(iv)        any
amounts required to be deposited pursuant to Section 3.07(b) of this Agreement in connection with net losses realized
on Permitted Investments with respect to funds held in such Loan Combination Custodial Account;


 


(v)         all
amounts with respect to any REO Property acquired in respect of the related Serviced Loan Combination transferred to such Loan
Combination Custodial Account, or the Master Servicer for deposit in such Loan Combination Custodial Account, from the related
REO Account pursuant to Section 3.16(b) of this Agreement;





 






    	-197- 



     


    

 


(vi)        all
Net Condemnation Proceeds, Net Insurance Proceeds and Net Liquidation Proceeds with respect to the related Serviced Loan Combination
(other than any Net Liquidation Proceeds received on or in respect of the related Mortgage Loan in connection with any of the
events described in clauses (iii) and (iv) of the definition of “Liquidation Event” in this Agreement);


 


(vii)       any
amounts received from the Mortgagor under the related Serviced Loan Combination that represent (A) recoveries of Property Protection
Expenses, or (B) any other reimbursements in accordance with the related Loan Documents, in each case to the extent not permitted
to be retained by the Master Servicer as provided herein; and


 


(viii)      any
other amounts required by the provisions of this Agreement to be deposited into such Loan Combination Custodial Account by the
Master Servicer or Special Servicer, including any recovery of any Unliquidated Advances;


 


provided,
however, that to the extent any such amounts are received after 2:00 p.m. Eastern time on any given Business Day, the Master
Servicer shall use commercially reasonable efforts to deposit such amounts into the related Loan Combination Custodial Account
within one (1) Business Day of receipt thereof but, in any event, the Master Servicer shall deposit such amounts into the related
Loan Combination Custodial Account within two (2) Business Days of receipt thereof.


 


(b)          The
foregoing requirements for deposits in each Loan Combination Custodial Account shall be exclusive, it being understood and agreed
that, without limiting the generality of the foregoing, to the extent provided herein, Ancillary Fees, Consent Fees, Assumption
Fees, assumption application fees, defeasance fees, review fees and other amounts that constitute other Additional Servicing Compensation
or other Additional Special Servicing Compensation need not be deposited in such Loan Combination Custodial Account by the Master
Servicer or the Special Servicer, as applicable, and, to the extent permitted by applicable law, the Master Servicer or the Special
Servicer, as applicable, shall be entitled to retain any such Ancillary Fees, Consent Fees, Assumption Fees, assumption application
fees, defeasance fees, review fees and/or other amounts that constitute other Additional Servicing Compensation or other Additional
Special Servicing Compensation received with respect to the Serviced Loan Combinations in accordance with Section 3.12
of this Agreement; provided that if the Master Servicer or the Special Servicer, as applicable, receives any such Ancillary Fees,
Consent Fees, Assumption Fees, assumption application fees, defeasance fees and/or amounts that constitute other Additional Servicing
Compensation or other Additional Special Servicing Compensation in excess of the percentage of such fees to which it is entitled
pursuant to Section 3.12(a) (in the case of the Master Servicer) or Section 3.12(c) (in the case of the Special
Servicer), then it shall remit to the other party (i.e. the Special Servicer (if Master Servicer has received the excess percentage
of such fees) or the Master Servicer (if Special Servicer has received the excess percentage of such fees), as applicable) the
percentage of such fees to which such other party is entitled pursuant to Section 3.12(a) or Section 3.12(c), as
applicable. The Master Servicer and the Special Servicer shall not deposit any Modification Fees received by the Master Servicer
or the Special Servicer, as applicable, with respect to any Serviced Loan Combination into the related Loan Combination Custodial
Account and shall instead apply such fees (except to the extent not permitted under the related Co-Lender Agreement) in accordance
with Section 3.14 of this Agreement. In the event





 






    	-198- 



     


    

 


that the Master Servicer deposits in a Loan Combination Custodial
Account any amount not required to be deposited therein, it may at any time withdraw such amount from such Loan Combination Custodial
Account, any provision herein to the contrary notwithstanding. The Master Servicer shall give written notice to the Certificate
Administrator, the related Serviced Companion Loan Holders and the Special Servicer of the location and account number of each
Loan Combination Custodial Account and shall notify the Certificate Administrator, the related Serviced Companion Loan Holder
and the Special Servicer in writing of any subsequent change thereof. Each Loan Combination Custodial Account shall be maintained
as a segregated account (or sub-account of such segregated account), separate and apart from trust funds created for mortgage

the following: (a) if the Purchase Price is paid for such Mortgage Loan, then such Person’s right to reimbursement
shall be limited to that portion of the Purchase Price that represents such expense in accordance with clause (f) of
the definition of Purchase Price, or (b) if no Purchase Price is paid or if an amount less than the Purchase Price is paid
and proceedings are instituted to enforce the related Mortgage Loan Seller’s payment or performance pursuant to the
applicable Mortgage Loan Purchase Agreement or if a Loss of Value Payment is made, then such Person shall be entitled to

If
and to the extent that the Master Servicer has reimbursed or made payment to itself or any other Person pursuant to any clause
of the prior paragraph above for any cost, expense, indemnity, fee or Property Advance or Advance Interest Amount thereon with
respect to a Loan Combination that represents the related Serviced Companion Loan’s allocable share of such cost, expense,
indemnity, fee, or Property Advance or Advance Interest Amount thereon (taking into account the subordinate nature of any related
Subordinate Companion Loan), the Master Servicer (with respect to Performing Serviced Loans) and the Special Servicer (with respect
to Specially Serviced Loans) shall use efforts consistent with the Servicing Standard to collect such amounts out of collections
on such Serviced Companion Loan (or, if and to the extent permitted under the related Co-Lender Agreement, from the related Serviced
Companion Loan Holder) and deposit all such amounts (collectively, with respect to such Serviced Companion Loan, the “Trust
Reimbursement Amount No.1”) collected from or on behalf of the related Serviced Companion Loan Holder into the Collection
Account.


 


The
Master Servicer shall also be entitled to make withdrawals from time to time, from the Collection Account of amounts necessary
for the payments or reimbursement of amounts required to be paid to the parties to, and/or the securitization trust created under,
the applicable Outside Servicing Agreement by the holder of each Outside Serviced Mortgage Loan pursuant to each Outside Serviced
Co-Lender Agreement. In the absence of manifest error, the Master Servicer may conclusively rely on the request for payments contemplated
by the preceding sentence.

Master Servicer shall keep and maintain separate accounting, on a Mortgage Loan-by-Mortgage Loan basis, for the purpose of justifying
any withdrawal from the Collection Account pursuant to subclauses (i)-(ix) of the third preceding paragraph.


 


The
Master Servicer shall pay to each of the Special Servicer (or to third party contractors at the direction of the Special Servicer),
the Operating Advisor, the Asset Representations Reviewer, the Trustee and the Certificate Administrator, as applicable, from
the applicable Collection Account, amounts permitted to be paid thereto from such account promptly upon receipt of a written statement
of an officer of the Special Servicer, an officer of the Operating Advisor, an officer of the Asset Representations Reviewer or

the Special Servicer (or such third party contractor), the Operating Advisor, the Asset Representations


 






    	-203- 



     


    

 


Reviewer, the Trustee
or the Certificate Administrator, as the case may be, is entitled (unless such payment to the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee or the Certificate Administrator, as the case may be, is clearly required
pursuant to this Agreement, in which case a written statement is not required). The Master Servicer may rely conclusively on any
such written statement and shall have no duty to recalculate the amounts stated therein. The parties seeking payment pursuant
to this Section shall each keep and maintain a separate accounting for the purpose of justifying any request for withdrawal
from each Collection Account, on a loan-by-loan basis.


 


With
respect to each Outside Serviced Mortgage Loan, the Master Servicer shall pay to, subject to Section 3.01(j)(i) and
(j)(ii), the related Outside Servicer, the related Outside Special Servicer, the related Outside Certificate Administrator

as applicable, on the first Business Day following the immediately preceding Determination Date, describing the item and amount
to which the related Outside Servicer, the related Outside Special Servicer, the related Outside Certificate Administrator or

shall have no duty to re-calculate the amounts stated therein.


 


The
Trustee, the Custodian, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer, the Depositor,
CREFC®, the Special Servicer and the Master Servicer shall in all cases have a right prior to the Certificateholders
to any funds on deposit in the Collection Account from time to time for the reimbursement or payment of the Servicing Fees (including

Operating Advisor Fees, Operating Advisor Consulting Fees (but only to the extent such Operating Advisor Consulting Fees are actually
received from the related Mortgagor(s)), Asset Representations Reviewer Ongoing Fee, Asset Representations Reviewer Asset Review
Fee (only to the extent such fee is payable by the Trust), CREFC® Intellectual Property Royalty License Fees and
(for each of such Persons other than CREFC®) their respective expenses hereunder (including without limitation
Additional Trust Fund Expenses) to the extent such fees, indemnity amounts and expenses are to be reimbursed or paid from amounts
on deposit in the Collection Account pursuant to this Agreement (and to have such amounts paid directly to third party contractors
for any invoices submitted to the Trustee, the Master Servicer or the Special Servicer, as applicable).


 


(b)         The
Certificate Administrator shall, upon receipt, deposit in each of the Lower-Tier REMIC Distribution Account, the Excess Interest
Distribution Account, the Interest Reserve Account and the Excess Liquidation Proceeds Reserve Account any and all amounts received

therein. If, as of 3:00 p.m., New York City time, on any Master Servicer Remittance Date or on such other date as any amount
referred to in the preceding sentence is required to be delivered hereunder, the Master Servicer shall not have delivered

then the Certificate Administrator shall, to the extent that a Responsible Officer of the Certificate Administrator has such knowledge,
provide notice of such failure to the Master Servicer by facsimile transmission sent to telecopy number (888) 706-3565 (or
such alternative number provided by the Master Servicer to the Certificate Administrator in writing) and by electronic mail at
NoticeAdmin@midlandls.com (or such alternative email address provided by the Master Servicer to the Certificate Administrator
in writing) as soon as possible, but in any event before 5:00 p.m., New York City time, on such day; provided, however,
that the Master Servicer will pay the Certificate Administrator interest on such late payment at the Prime Rate until such late
payment is received by the Certificate Administrator.


 


(c)         If
any Loss of Value Payments are deposited into the Loss of Value Reserve Fund with respect to any Mortgage Loan or any related
REO Property, then the Special Servicer shall (provided that, with respect to clause (v) below, the Certificate
Administrator shall have provided the Master Servicer and the Special Servicer with five Business Days’ prior notice of

(i)          to
reimburse the Master Servicer, the Special Servicer or the Trustee, in accordance with Section 3.06(a) of this Agreement,

would constitute an Additional Trust Fund Expense, and to pay, in accordance with Section 3.06(a) of this Agreement, any
unpaid Liquidation Fee due and owing to the Special Servicer with respect to such Mortgage Loan or any related REO Property;


 


(iii)        to
offset any portion of Realized Losses that are attributable to such Mortgage Loan or related REO Property (as calculated without
regard to the application of such Loss of Value Payments), incurred with respect to such Mortgage Loan or any related successor
REO Mortgage Loan;


 


(iv)        following
the occurrence of a Liquidation Event with respect to such Mortgage Loan or any related REO Property and any related transfers
from the Loss of Value Reserve Fund with respect to the items contemplated by the immediately preceding clauses (i)-(iii)
above as to such Mortgage Loan, to cover the items contemplated by the immediately preceding clauses (i)-(iii) in respect
of any other Mortgage Loan or REO Mortgage Loan; and


 


(v)         on
the final Distribution Date after all distributions have been made as set forth in clauses (i) through (iv) above, to each
Mortgage Loan Seller, its pro rata share, based on the amount that it contributed, net of any amount contributed by such
Mortgage

Loan Seller that was used pursuant to clauses (i)-(iii) to offset any portion of Realized Losses that are attributable
to such Mortgage Loan or related REO Property, Additional Trust Fund Expenses or any Nonrecoverable Advances incurred with respect
to the Mortgage Loan related to such contribution.

Loss of Value Payments transferred to the Collection Account pursuant to clauses (i) - (iii) of the prior paragraph shall
be treated as Liquidation Proceeds received by the Trust in respect of the related Mortgage Loan or any successor REO Mortgage
Loan with respect thereto for which such Loss of Value Payments were received; and any Loss of Value Payments transferred to the
Collection Account pursuant to clause (iv) of the prior paragraph shall be treated as Liquidation Proceeds received by
the Trust in respect of the Mortgage Loan or REO Mortgage Loan for which such Loss of Value Payments are being transferred to
the Collection Account to cover an item contemplated by clauses (i)-(iii) of the prior paragraph.

respect of the related Mortgage Loan (or any successor REO Mortgage Loan) or the related Serviced Companion Loan (or any
successor REO Companion Loan); and provided, further, that if such Advance is a P&I Advance with respect to the related

payable to the Trust with respect to the related Mortgage Loan (or any successor REO Mortgage Loan);


 


(vi)        to
make such payments and reimbursements out of Penalty Charges and Modification Fees on deposit in such Loan Combination Custodial
Account as are contemplated by the related Co-Lender Agreement and Section 3.14 of this Agreement;


 


(vii)       to
withdraw any amount deposited into such Loan Combination Custodial Account that was not required to be deposited therein;


 


(viii)      if
the related Serviced Companion Loan (or any successor REO Companion Loan with respect thereto) is part of an Other Securitization
Trust, to the extent required


 






    	-208- 



     


    

 


by the related Co-Lender Agreement, to reimburse the applicable party to the related Other Pooling
and Servicing Agreement for any advances of delinquent monthly debt service payments made thereby with respect to such Serviced
Companion Loan (or REO Companion Loan), together with interest thereon, provided that such reimbursement, together with interest,
shall be made solely out of payments and other collections on such Serviced Companion Loan (or REO Companion Loan); or


 


(ix)          to
clear and terminate such Loan Combination Custodial Account pursuant to Section 9.01 of this Agreement.


 


The
Master Servicer shall keep and maintain separate accounting, on a Mortgage Loan-by-Mortgage Loan and Companion Loan-by-Companion
Loan basis, for the purpose of justifying any withdrawal from each Loan Combination Custodial Account pursuant to subclauses (i)
- (ix) above. If and to the extent that the Master Servicer has reimbursed or made payment to itself or any other Person pursuant
to any clause of the prior paragraph above for any cost, expense, indemnity, or Property Advance or Advance Interest Amount thereon
with respect to a Serviced Loan Combination out of monies allocable to the related Mortgage Loan (or any successor REO Mortgage
Loan) to an extent that the Trust has borne some or all of the related Serviced Companion Loan’s allocable share of such
cost, expense, indemnity, or Property Advance or Advance Interest Amount thereon (taking into account the subordinate nature of
any related Subordinate Companion Loan to the extent set forth in, and in accordance with, the related Co-Lender Agreement), the
Master Servicer shall use efforts consistent with the Servicing Standard to collect such amounts disproportionately borne by the
Trust out of collections on such Serviced Companion Loan (or, if and to the extent permitted under the related Co-Lender Agreement,
from the related Serviced Companion Loan Holder) and deposit all such amounts (collectively, with respect to such Serviced Companion
Loan, the “Trust Reimbursement Amount No.2” and, together with Trust Reimbursement Amount No.1, the “Trust
Reimbursement Amount”) collected from or on behalf of the related Serviced Companion Loan Holder into the Collection
Account.


 


The
Master Servicer shall pay to each of the Special Servicer (or to third party contractors at the direction of the Special Servicer),
the Operating Advisor, the Trustee, the Certificate Administrator and an advancing party under any Other Pooling and Servicing
Agreement, as applicable, from the applicable Loan Combination Custodial Account, amounts permitted to be paid thereto from such
account promptly upon receipt of a written statement of an officer of the Special Servicer, an officer of the Operating Advisor,
a Responsible Officer of the Trustee or the Certificate Administrator or an officer of such advancing party under such Other Pooling
and Servicing Agreement, as the case may be, describing the item and amount to which the Special Servicer (or such third party
contractor), the Operating Advisor, the Trustee, the Certificate Administrator or such advancing party under such Other Pooling
and Servicing Agreement, as the case may be, is entitled (unless such payment to the Special Servicer, the Operating Advisor,
the Trustee or the Certificate Administrator, as the case may be, is clearly required pursuant to this Agreement, in which case
a written statement is not required). The Master Servicer may rely conclusively on any such written statement and shall have no
duty to re-calculate the amounts stated therein. The parties seeking payment pursuant to this Section shall each keep and maintain
separate accounting for the purpose of justifying any request for withdrawal from each Loan Combination Custodial Account, on
a loan-by-loan basis.


 






    	-209- 



     


    

 


The
Trustee, the Depositor, the Operating Advisor, the Certificate Administrator, the Special Servicer and the Master Servicer shall
in all cases have a right prior to the Certificateholders to any funds on deposit in a Loan Combination Custodial Account from
time to time for the reimbursement or payment of the Servicing Fees (including investment income), or Special Servicing Compensation,
Advances, Advance Interest Amounts and their respective indemnity amounts or expenses hereunder to the extent such fees, indemnity
amounts and expenses are to be reimbursed or paid from amounts on deposit in such Loan Combination Custodial Account pursuant
to this Agreement and the related Co-Lender Agreement (and to have such amounts paid directly to third party contractors for any
invoices approved by the Trustee, the Depositor, the Certificate Administrator, the Master Servicer or the Special Servicer, as
applicable); provided, however, for the avoidance of doubt, neither the Trustee/Certificate Administrator Fees nor
the Operating Advisor Fee shall be paid from funds on deposit in a Loan Combination Custodial Account.


 


After
the Determination Date, and on or prior to the Business Day immediately preceding the Master Servicer Remittance Date, in each
calendar month (and also on the Business Day immediately following the receipt of any funds from the REO Account for any REO Property
related to the applicable Serviced Loan Combination, if such funds are received after the Determination Date and before the Distribution
Date in any calendar month and were not available for any earlier transfer to the Collection Account in such calendar month),
the Master Servicer shall remit for deposit in the Collection Account all amounts on deposit in a Loan Combination Custodial Account
payable to the Trust pursuant to the related Co-Lender Agreement with respect to the related Mortgage Loan (or any successor REO
Mortgage Loan), including any applicable Trust Reimbursement Amount; and on or prior to the related Serviced Loan Combination
Remittance Date in each calendar month (and also on the Business Day immediately following the receipt of any funds from the REO
Account for any REO Property related to the applicable Serviced Loan Combination, if such funds are received after the Determination
Date and before the Distribution Date in any calendar month), the Master Servicer shall remit to the related Serviced Companion
Loan Holder all amounts on deposit in a Loan Combination Custodial Account payable to such Serviced Companion Loan Holder pursuant
to the related Co-Lender Agreement with respect to the related Serviced Companion Loan (or any successor REO Companion Loan),
exclusive of any applicable Trust Reimbursement Amount, in each case, prior to the required remittance from the Collection Account
to the Certificate Administrator for deposit into the Lower-Tier REMIC Distribution Account on such Master Servicer Remittance
Date.


 


(b)         Notwithstanding
anything to the contrary contained herein, with respect to each Serviced Companion Loan, the Master Servicer shall withdraw from
the related Loan Combination Custodial Account and remit to the related Serviced Companion Loan Holder, within one (1) Business
Day of receipt of properly identified funds, any amounts that represent late collections or Principal Prepayments received by
the Master Servicer from the related Mortgagor that are allocable to such Serviced Companion Loan or any successor REO Loan with
respect thereto (exclusive of any portion of such amount paid or reimbursed to any third party in accordance with the related
Co-Lender Agreement) unless such amount would otherwise be included in the monthly remittance to the related Serviced Companion
Loan Holder for such month pursuant to Section 3.06A(a); provided, however, that to the extent any such amounts
are received after 3:00 p.m. Eastern time on any given Business Day, the Master Servicer shall use commercially reasonable efforts
to remit such amounts to the related Serviced Companion Loan


 






    	-210- 



     


    

 


Holder within one (1) Business Day of receipt of properly identified
funds but, in any event, the Master Servicer shall remit such amounts within two (2) Business Days of receipt of properly identified
funds.


 


Section 3.07           Investment
of Funds in the Collection Account, the REO Account, the Mortgagor Accounts, and Other Accounts.


 


(a)          The
Master Servicer, or with respect to any REO Account and any Loss of Value Reserve Fund, the Special Servicer, may direct any depository
institution maintaining the Collection Account, any Loan Combination Custodial Account, any Mortgagor Account (subject to the
second succeeding sentence), any REO Account or any Loss of Value Reserve Fund (each of the Collection Account, any Loan Combination
Custodial Account, any REO Account, any Loss of Value Reserve Fund and any Mortgagor Account, for purposes of this Section 3.07,
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 Master Servicer or the Special Servicer 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. In the case of any Escrow Account or Lock-Box Account (the “Mortgagor Accounts”), the Master Servicer
shall act upon the written request of the related Mortgagor or Manager to the extent the Master Servicer is required to do so
under the terms of the respective Mortgage Loan (or Serviced Loan Combination) or related documents, provided that in the
absence of appropriate written instructions from the related Mortgagor or Manager meeting the requirements of this Section 3.07,
the Master Servicer shall have no obligation to, but will be entitled to, direct the investment of funds in such accounts in Permitted
Investments. 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 or a nominee of the Trustee (in each case for the benefit of the Certificateholders).
The Trustee (for the benefit of the Certificateholders) shall have sole control (except with respect to investment direction,
which shall be in the control of the Master Servicer (with respect to the Collection Account, any Loan Combination Custodial Account
or any Mortgagor Account) or the Special Servicer (with respect to any REO Accounts and any Loss of Value Reserve Fund), as applicable,
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 Trustee or its nominee (which shall initially be the Master 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 (for the benefit of the Certificateholders). Neither the Trustee nor the Certificate Administrator
shall have any responsibility or liability with respect to the investment directions of the Master Servicer or the Special Servicer,
any Mortgagor or Manager or any losses resulting therefrom, whether from Permitted Investments or otherwise. The Master Servicer
shall have no responsibility or liability with respect to the investment direction of the Special Servicer, any Mortgagor or Manager
or any losses resulting therefrom, whether from Permitted Investments or otherwise. The Special Servicer shall have no responsibility
or liability with respect to the investment direction of the Master Servicer, any Mortgagor or any property manager 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


 






    	-211- 



     


    

 


Investment payable on demand, the Master Servicer (or the Special Servicer in the case
of REO Accounts and any Loss of Value Reserve Fund), shall: (x) 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
(y) demand payment of all amounts due thereunder promptly upon determination by the Master Servicer (or the Special Servicer
in the case of REO Accounts and any Loss of Value Reserve Fund) that such Permitted Investment would not constitute a Permitted
Investment in respect of funds thereafter on deposit in the related Investment Account. Amounts on deposit in the Distribution
Account, the Excess Interest Distribution Account, the Excess Liquidation Proceeds Reserve Account and the Interest Reserve Account
(each, a “Certificate Administrator Account”) shall remain uninvested.


 


(b)         All
income and gain realized from investment of funds deposited in any Investment Account shall be for the benefit of the Master Servicer,
except with respect to the investment of funds deposited in (i) any Mortgagor Account to the extent required under the Mortgage
Loan (or Serviced Loan Combination) or applicable law to be for the benefit of the related Mortgagor or (ii) any REO Account
and any Loss of Value Reserve Fund, which shall be for the benefit of the Special Servicer, and if held in the Collection Account,
a Loan Combination Custodial Account or an REO Account, shall be subject to withdrawal by the Master Servicer or the Special Servicer,
as applicable, in accordance with Section 3.06, Section 3.06A or Section 3.16(b) of this Agreement,
as applicable. The Master Servicer (or with respect to any REO Account and any Loss of Value Reserve Fund, the Special Servicer)
shall deposit from its own funds into any applicable Investment Account, the amount of any loss incurred in respect of any such
Permitted Investment immediately upon realization of such loss (except with respect to losses incurred as a result of the related
Mortgagor or Manager exercising its power under the related Loan Documents to direct such investment in such Mortgagor Account);
provided, however, that the Master Servicer or Special Servicer, as applicable, may reduce the amount of such payment
to the extent it forgoes any investment income in such Investment Account otherwise payable to it. The Master Servicer shall also
deposit from its own funds in any Mortgagor Account the amount of any loss incurred in respect of Permitted Investments, except
to the extent that amounts are invested for the benefit of the Mortgagor under the terms of the Mortgage Loan (or Serviced Loan
Combination) or applicable law. Notwithstanding the foregoing, neither the Master Servicer nor the Special Servicer (in their
respective capacities as Master Servicer and Special Servicer, respectively) shall be required to deposit any loss on an
investment of funds in an Investment Account if such loss is incurred solely as a result of the insolvency of the federal or state
chartered depository institution or trust company that holds such Investment Account, so long as such depository institution or
trust company is not the Person or an Affiliate of the Person maintaining such account hereunder and satisfied the qualifications
set forth in the definition of Eligible Account both (1) at the time such investment was made and (2) as of the date
that is 30 days prior to the insolvency.


 


(c)         Except
as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment,
or if a default occurs in any other performance required under any Permitted Investment, the Trustee may, and upon the request
of Holders of Certificates representing greater than 50% of the Percentage Interests of any Class shall, take such action as may
be appropriate to enforce such payment or performance,


 






    	-212- 



     


    

 


including the institution and prosecution of appropriate proceedings. In
the event the Trustee takes any such action, the Trust Fund shall pay or reimburse the Trustee for all reasonable out-of-pocket
expenses, disbursements and advances incurred or made by the Trustee in connection therewith. In the event that the Trustee does
not take any such action, the Master Servicer may, but is not obligated to, take such action at its own cost and expense.


 


Section 3.08           Maintenance
of Insurance Policies and Errors and Omissions and Fidelity Coverage.


 


(a)         The
Master Servicer on behalf of the Trustee, as mortgagee of record, shall use efforts consistent with the Servicing Standard to
cause the related Mortgagor to maintain, to the extent required by each Mortgage Loan (other than an Outside Serviced Mortgage
Loan) and each Serviced Companion Loan (except to the extent that the failure to maintain such insurance coverage is an Acceptable
Insurance Default), and if the Mortgagor does not so maintain, shall itself maintain (subject to the provisions of this Agreement
concerning Nonrecoverable Advances and to the extent the Trustee as mortgagee of record has an insurable interest and to the extent
available at commercially reasonable rates), (i) fire and hazard insurance (and windstorm insurance, if applicable) with
extended coverage on the related Mortgaged Property in an amount which is at least equal to the lesser of (a) one hundred
percent (100%) of the then “full replacement cost” of the improvements and equipment (excluding foundations, footings
and excavation costs), without deduction for physical depreciation, and (b) the outstanding principal balance of the related
Mortgage Loan and the related Serviced Companion Loan or such greater amount as is necessary to prevent any reduction in such
policy by reason of the application of co-insurance provisions and to prevent the Trustee thereunder from being deemed to be a
co-insurer and provided such policy shall include a “replacement cost” rider, (ii) insurance providing coverage
against 18 months (or such longer period or with such extended period endorsement as provided in the related Mortgage or
other Loan Document) of rent interruptions and (iii) such other insurance as is required in the related Mortgage Loan and
the related Serviced Companion Loan. Subject to Section 3.16 of this Agreement, the Special Servicer in accordance
with the Servicing Standard and to the extent available at commercially reasonable rates (as determined by the Special Servicer
in accordance with the Servicing Standard), shall cause to be maintained for each REO Property (other than an REO Property related
to an Outside Serviced Mortgage Loan) no less insurance coverage than was previously required of the Mortgagor under the related
Loan Documents (except to the extent that the failure to maintain such insurance coverage is an Acceptable Insurance Default);
provided that to the extent the Loan Documents require the related Mortgagor to maintain insurance with an insurer rated
better than as indicated in the definition of “Qualified Insurer”, the Master Servicer may, without a Rating Agency
Confirmation or the approval of the Special Servicer, to the extent consistent with the Servicing Standard, permit the related
Mortgagor to maintain insurance with an insurer that does not meet the requirements of the Loan Documents so long as the related
Mortgagor maintains insurance with an insurer rated at least as indicated in the definition of “Qualified Insurer”.
All insurance for an REO Property shall be from a Qualified Insurer, if available from a Qualified Insurer, and if not available
from a Qualified Insurer, from an insurance provider that is rated the next highest available rating who is offering such insurance
at commercially reasonable rates. Any amounts collected by the Master Servicer or the Special Servicer under any such policies
(other than amounts required to be applied to the restoration or repair of the related Mortgaged Property or amounts to be released
to the Mortgagor in accordance with the terms of the related Loan Documents) shall be deposited into


 






    	-213- 



     


    

 


the Collection Account
pursuant to Section 3.05 of this Agreement or the Loan Combination Custodial Account pursuant to Section 3.05A
of this Agreement, as applicable, subject to withdrawal pursuant to Section 3.05, Section 3.05A, Section
3.06 or Section 3.06A of this Agreement. Any cost incurred by the Master Servicer or the Special Servicer in maintaining
any such insurance shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid principal
balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit. It is understood and agreed
that no other additional insurance other than flood insurance or earthquake insurance subject to the conditions set forth below
is to be required of any Mortgagor or to be maintained by the Master Servicer other than pursuant to the terms of the related
Loan Documents and pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such
additional insurance. If the related Mortgaged Property (other than an REO Property and other than with respect to an Outside
Serviced Mortgage Loan) is located in a federally designated special flood hazard area, the Master Servicer will use efforts consistent
with the Servicing Standard to cause the related Mortgagor to maintain, to the extent required by each Serviced Loan, and if the
related Mortgagor does not so maintain, shall itself obtain (subject to the provisions of this Agreement concerning Nonrecoverable
Advances) and maintain flood insurance in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the
unpaid principal balance of the related Mortgage Loan and the related Serviced Companion Loan and (ii) the maximum amount of such
insurance required by the terms of the related Mortgage Loan or Serviced Loan Combination and as is available for the related
property under the national flood insurance program (assuming that the area in which such property is located is participating
in such program). If a Mortgaged Property (other than an REO Property) is related to a Serviced Loan pursuant to which earthquake
insurance is required to be maintained pursuant to the terms of the Mortgage Loan or Serviced Loan Combination, the Master Servicer
shall use efforts consistent with the Servicing Standard to cause the related Mortgagor to maintain, and if the related Mortgagor
does not so maintain will itself obtain (subject to the provisions of this Agreement concerning Nonrecoverable Advances and for
so long as such insurance continues to be available at commercially reasonable rates) and maintain earthquake insurance in respect
thereof, in the amount required by the Mortgage Loan or Serviced Loan Combination or, if not specified, in-place at origination.
If an REO Property (other than an REO Property related to the Outside Serviced Mortgage Loan) (i) is located in a federally
designated special flood hazard area or (ii) is related to a Serviced Loan with respect to which earthquake insurance would
be appropriate in accordance with the Servicing Standard and such insurance is available at commercially reasonable rates, the
Special Servicer will obtain (subject to the provisions of this Agreement concerning Nonrecoverable Advances) and maintain flood
insurance and/or earthquake insurance in respect thereof providing the same coverage as described in this Section 3.08(a).
Out-of-pocket expenses incurred by the Master Servicer or Special Servicer in maintaining insurance policies pursuant to this
Section 3.08 shall be advanced by the Master Servicer as a Property Advance and shall be reimbursable to the Master
Servicer with interest at the Advance Rate. The Master Servicer (or the Special Servicer, with respect to REO Properties) agrees
to prepare and present, on behalf of itself, the Trustee and the Certificateholders and the Serviced Companion Loan Holders, claims
under each related insurance policy maintained by it pursuant to this Section 3.08(a) in a timely fashion in accordance
with the terms of such policy and to take such reasonable steps as are necessary to receive payment or to permit recovery thereunder.
All insurance policies required to be maintained by the Master Servicer or Special Servicer hereunder shall name the Trustee or
the Master Servicer or the Special Servicer, on behalf of the Trustee as the mortgagee, as loss payee, and shall be issued by
Qualified Insurers, if available


 






    	-214- 



     


    

 


from a Qualified Insurer, and if not available from a Qualified Insurer, from an insurance provider
that is rated the next highest available rating who is offering such insurance at commercially reasonable rates. Notwithstanding
the foregoing: (A) the Master Servicer shall not be required to maintain any earthquake or environmental insurance policy
on any Mortgaged Property and the Special Servicer shall not be required to maintain any earthquake or environmental insurance
policy on any REO Property, in each case unless such insurance is required to be maintained under the related Loan Documents and
is available at commercially reasonable rates; provided, however, that neither the Master Servicer nor the Special
Servicer shall have any obligation to maintain such earthquake or environmental insurance policy required under the related Loan
Documents if the originator of the Serviced Mortgage Loan or Serviced Loan Combination waived compliance with such insurance requirements
(and if the applicable Master Servicer does not cause the Mortgagor to maintain or does not itself maintain such earthquake or
environmental insurance policy on any Mortgaged Property, the Special Servicer shall have the right, but not the duty, to obtain,
at the Trust’s expense, earthquake or environmental insurance on any Mortgaged Property securing a Specially Serviced Loan
or an REO Property so long as such insurance is available at commercially reasonable rates); (B) with respect to the Master
Servicer’s obligation to cause the related Mortgagor to maintain such insurance, the Master Servicer shall have no obligation
beyond using its efforts consistent with the Servicing Standard to cause any Mortgagor to maintain the insurance required to be
maintained or that the lender is entitled to reasonably require, subject to applicable law, under the related Loan Documents;
and (C) in making determinations as to the availability of insurance at commercially reasonable rates or otherwise, the Master
Servicer or the Special Servicer, as applicable, shall, to the extent consistent with the Servicing Standard, be entitled to rely,
at its own expense, on insurance consultants in making such determination and any such determinations by the Master Servicer or
the Special Servicer, as applicable, need not be made more frequently than annually but in any event shall be made at the approximate
date on which the Master Servicer or the Special Servicer, as applicable, receives notice of the renewal, replacement or cancellation
of coverage.


 


Notwithstanding
the foregoing, the Master Servicer or Special Servicer, as applicable, will not be required to maintain, and shall not cause a
Mortgagor to be in default with respect to the failure of the related Mortgagor 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 has determined in accordance with
the Servicing Standard that the failure to maintain such insurance is an Acceptable Insurance Default; provided that, during
the period that the Special Servicer is evaluating such insurance hereunder, the Master Servicer shall not be liable for any loss
related to its failure to require the Mortgagor to maintain terrorism insurance and shall not be in default of its obligations
hereunder as a result of such failure. The Special Servicer shall promptly notify the Master Servicer of each determination under
this paragraph.


 


(b)         (i)  If
the Master Servicer or the Special Servicer obtains and maintains a blanket insurance policy insuring against fire and
hazard losses on all of the Mortgaged Properties (other than REO Properties and other than Mortgaged Properties that secure
the Outside Serviced Mortgage Loans) as to which the related Mortgagor has not maintained insurance required by the related
Mortgage Loan or, if applicable, related Serviced Loan Combination (other than any Mortgagor that is required under the
related Loan Documents to maintain insurance with an insurer rated better than as indicated in the definition of
“Qualified Insurer” that maintains insurance with an insurer rated at least as indicated in the definition of
“Qualified Insurer”) or the Special Servicer


 






    	-215- 



     


    

 


obtains and maintains a blanket insurance policy
insuring against fire and hazard losses on all of the REO Properties (other than REO Properties acquired in respect of the Outside
Serviced Mortgage Loan), as required under this Agreement, as the case may be, then the Master Servicer or the Special Servicer,
as the case may be, shall conclusively be deemed to have satisfied its respective obligations concerning the maintenance of insurance
coverage set forth in Section 3.08(a) of this Agreement. Any such blanket insurance policy shall be maintained with
a Qualified Insurer. A blanket insurance policy may contain a deductible clause, in which case the Master Servicer or the Special
Servicer, as applicable, shall, in the event that (i) there shall not have been maintained on the related Mortgaged Property
a policy otherwise complying with the provisions of Section 3.08(a) of this Agreement, and (ii) there shall have
been one or more losses which would have been covered by such a policy had it been maintained, immediately deposit into the Collection
Account or, if applicable, related Loan Combination Custodial Account from its own funds the amount not otherwise payable under
the blanket policy because of such deductible clause to the extent that any such deductible exceeds the deductible limitation
that pertained to the related Mortgage Loan or Serviced Loan Combination or, in the absence of any such deductible limitation,
the deductible limitation which is consistent with the Servicing Standard. In connection with its activities as Master Servicer
or the Special Servicer hereunder, as applicable, the Master Servicer and the Special Servicer, respectively, agree to prepare
and present, on behalf of itself, the Trustee and Certificateholder and any related Serviced Companion Loan Holder, claims under
any such blanket policy which it maintains in a timely fashion in accordance with the terms of such policy and to take such reasonable
steps as are necessary to receive payment or permit recovery thereunder.


 


(ii)         If
the Master Servicer causes any Mortgaged Property (other than any REO Property and other than any Mortgaged Property that secures
an Outside Serviced Mortgage Loan) or the Special Servicer causes any REO Property (other than an REO Property acquired in respect
of an Outside Serviced Mortgage Loan) to be covered by a master force placed insurance policy and such policy shall be issued
by a Qualified Insurer and provide no less coverage in scope and amount for such Mortgaged Property or REO Property than the insurance
required to be maintained pursuant to Section 3.08(a) of this Agreement, then the Master Servicer or Special Servicer,
as the case may be, shall conclusively be deemed to have satisfied its respective obligations to maintain insurance pursuant to
Section 3.08(a) of this Agreement. Such policy may contain a deductible clause, in which case the Master Servicer
or the Special Servicer, as applicable, shall, in the event that (i) there shall not have been maintained on the related
Mortgaged Property or REO Property a policy otherwise complying with the provisions of Section 3.08(a), and (ii) there
shall have been one or more losses which would have been covered by such a policy had it been maintained, immediately deposit
into the Collection Account or, if applicable, related Loan Combination Custodial Account from its own funds the amount not otherwise
payable under such policy because of such deductible to the extent that any such deductible exceeds the deductible limitation
that pertained to the related Mortgage Loan and/or related Serviced Companion Loan(s) related thereto, or, in the absence of any
such deductible limitation, the deductible limitation which is consistent with the Servicing Standard.


 


(iii)        In
either case, if the Master Servicer or Special Servicer, as applicable, causes any Mortgaged Property or REO Property to be covered
by such “force-placed”


 






    	-216- 



     


    

 


insurance policy, the incremental costs of such insurance applicable to such Mortgaged Property
or REO Property (i.e., other than any minimum or standby premium payable for such policy whether or not any Mortgaged Property
or REO Property is covered thereby) shall be paid as a Property Advance. Any legal fees or other out-of-pocket costs incurred
in accordance with the Servicing Standard in connection with any claim under an insurance policy described above (whether by the
Master Servicer or Special Servicer) shall be paid by, and reimbursable to, the Master Servicer as a Property Advance.


 


(c)         The
Master Servicer and the Special Servicer shall each obtain and maintain in effect a fidelity bond or similar form of insurance
coverage (which may provide blanket coverage) or a combination of fidelity bond and insurance coverage, in such form as is consistent
with the Servicing Standard and in such amounts that are consistent with the Servicing Standard, insuring against loss occasioned
by fraud, theft or other intentional misconduct of the officers and employees of the Master Servicer or the Special Servicer,
as the case may be. The Master Servicer and the Special Servicer each shall be deemed to have complied with this provision if
one of its respective Affiliates has such fidelity bond coverage and, by the terms of such fidelity bond, the coverage afforded
thereunder extends to the Master Servicer or the Special Servicer, as applicable. In addition, the Master Servicer and the Special
Servicer shall each keep in force during the term of this Agreement a policy or policies of insurance covering loss occasioned
by the errors and omissions of its officers and employees in connection with its obligations to service the Mortgage Loans and
any Serviced Companion Loans hereunder in such form as is consistent with the Servicing Standard and in such amounts as are consistent
with the Servicing Standard. Notwithstanding the foregoing, so long as the long-term unsecured debt rating or deposit account
rating of the Master Servicer (or its corporate parent) or the Special Servicer (or its corporate parent) is not in any event
less than “A3” as rated by Moody’s and “A-” as rated by Fitch, the Master Servicer or the Special
Servicer, as applicable, may self-insure for the fidelity bond and errors and omissions coverage otherwise required above. The
Master Servicer shall cause each and every Sub-Servicer it has engaged to maintain or cause to be maintained by an agent or contractor
servicing any Mortgage Loan or Serviced Loan Combination on behalf of such Sub-Servicer, a fidelity bond and an errors and omissions
insurance policy which satisfy the requirements for the fidelity bond and the errors and omissions policy to be maintained by
the Master Servicer to comply with the foregoing. All fidelity bonds and policies of errors and omissions insurance obtained under
this Section 3.08(c) shall be issued by a Qualified Insurer.


 


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

(a)         Upon
receipt of any request of a waiver or consent in respect of a due-on-sale or due-on-encumbrance provision under the Loan Documents
of a Serviced Loan, the Special Servicer shall promptly process and analyze such request, including the preparation of written
materials in connection with such analysis, and determine in a manner consistent with the Servicing Standard whether to waive
any right to accelerate payment the lender may have, or grant


 






    	-217- 



     


    

 


its consent, under the due-on-sale or due-on-encumbrance provision
of such Serviced Loan. If the Master Servicer receives any such request with respect to Performing Serviced Loans, the Master
Servicer shall promptly deliver a copy of such request to the Special Servicer. Notwithstanding the forgoing, with respect to
any Performing Serviced Loan as to which the Master Servicer and the Specially Servicer mutually agree, the Master Servicer shall
process and analyze any such request, including the preparation of written materials in connection with such analysis, in accordance
with the Servicing Standard, and provide its written recommendation and analysis to the Special Servicer as to whether or not
to waive any right to accelerate payment the lender may have, or grant its consent, under the due-on-sale or due-on-encumbrance
provision of such Serviced Loan (with any such recommended course of action to be subject to the Special Servicer’s consent).


 


Both
the Master Servicer and the Special Servicer (as applicable in accordance with the first paragraph of this Section
3.09(a)) each in a manner consistent with the Servicing Standard and each on behalf of the Trustee as the mortgagee of
record, shall, to the extent permitted by applicable law, enforce the restrictions contained in the related Loan Documents on
transfers or further encumbrances of the related Mortgaged Property and on transfers or further encumbrances of interests in
the related Mortgagor, unless following receipt of a request for a waiver or consent in respect of a due-on-sale or
due-on-encumbrance provision the Master Servicer (to the extent that it is processing such request pursuant to the first
paragraph of this Section 3.09(a), with the written consent of the Special Servicer, which consent shall be deemed
given if not denied within 15 Business Days (or, with respect to a Serviced Loan Combination, such longer period as required
by the related Co-Lender Agreement, but in no event less than 5 Business Days after the time period set forth in such
Co-Lender Agreement for review by any related Serviced Companion Loan Holder or its Companion Loan Holder Representative)
after the Special Servicer’s receipt (unless earlier objected to) of the written recommendation and analysis of the
Master Servicer for such action and any additional information reasonably available to the Master Servicer that the Special
Servicer may reasonably request for the analysis of such request, which recommendation and information may be delivered in an
electronic format reasonably acceptable to the Master Servicer and the Special Servicer) or the Special Servicer, as
applicable, has determined, consistent with the Servicing Standard, that the waiver of such restrictions or granting of
consent would be in accordance with the Servicing Standard. Promptly after the Master Servicer (with the written consent of
the Special Servicer to the extent required pursuant to this Section 3.09(a)) or the Special Servicer, as
applicable, has made any determination to grant a waiver in respect of a due-on-sale or due-on-encumbrance provision, the
Master Servicer or the Special Servicer, as applicable, shall: (1) deliver to the Trustee, the Certificate Administrator,
each other party to this Agreement and, for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section
12.13 of this Agreement, the Rule 17g-5 Information Provider an Officer’s Certificate setting forth the basis for
such determination; provided that, notwithstanding anything herein to the contrary, no such Officer’s Certificate shall
be required to be delivered if the Master Servicer or Special Servicer, as applicable, is granting consent to an assumption
pursuant to this Section 3.09(a) in accordance with the terms of the related Loan Documents and there is no material
waiver of any conditions or any other provisions of the related Loan Documents with respect thereto; and (2) close the
related transaction, subject to the consent of the Special Servicer obtained as described above (if the Master Servicer is
processing such request), any applicable consultation rights of the Operating Advisor (to the extent the Operating Advisor
has consultation rights pursuant to Section 3.29 or Section 6.09) and the consultation and/or consent rights
(if any) of the related Directing


 






    	-218- 



     


    

 


Holder or the consultation rights
of any related Serviced Pari Passu Companion Loan Holder (or its Companion Loan Holder Representative) as provided in this Section
3.09(a), and as otherwise provided in the related Co-Lender Agreement and this Agreement, and subject to Sections 3.09(b),
3.21, 3.24, 3.25 and Section 3.28; provided, however, that neither the Master Servicer nor the Special
Servicer shall enter into any such agreement to the extent that any terms thereof would result in (i) the imposition of a tax
on a Trust REMIC under the REMIC Provisions or cause either Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust
to fail to qualify as a grantor trust under subpart E, part I of subchapter J of the Code for federal income tax purposes at any
time that any Certificate is outstanding or (ii) create any lien on a Mortgaged Property that is senior to, or on parity with,
the lien of the related Mortgage.


 


With
respect to all Serviced Mortgage Loans and each Serviced Loan Combination, the Special Servicer shall, prior to consenting to
a proposed action of the Master Servicer pursuant to this Section 3.09 that constitutes a Major Decision, and prior to
itself taking such an action, obtain the written consent of the related Outside Controlling Note Holder (to the extent set forth
in the related Co-Lender Agreement if a Serviced Outside Controlled Loan Combination is involved) or the Controlling Class Representative
(if any other Serviced Loan(s) (exclusive of any Excluded Mortgage Loan(s)) are involved and a Control Termination Event does
not exist), as applicable, which consent shall be deemed given ten (10) Business Days after receipt (unless earlier objected to)
by such related Directing Holder of the Major Decision Reporting Package for such action, which recommendation and information
may be delivered in an electronic format reasonably acceptable to the related Directing Holder and the Master Servicer or the
Special Servicer, as applicable. In addition, neither the Master Servicer nor the Special Servicer may waive the rights of the
lender or grant its consent under any “due-on-encumbrance” provision unless (1) the Master Servicer or the Special
Servicer, as applicable (in each case, if it is the party processing the related request pursuant to this Section 3.09(a)),
shall have received a prior written Rating Agency Confirmation with respect to such action, or (2) the related Serviced Mortgage
Loan (including a Serviced Mortgage Loan related to a Serviced Loan Combination) (A) represents less than 2% of the aggregate
principal balance of all of the Mortgage Loans in the Trust Fund, (B) has a principal balance that is equal to or less than $20,000,000,
(C) has a Loan-to-Value Ratio equal to or less than 85% (including any existing and proposed debt), (D) has a Debt Service Coverage
Ratio equal to or greater than 1.20x (in each case, determined based upon the aggregate of the Stated Principal Balance of the
Serviced Mortgage Loan, any related Serviced Companion Loan (if applicable) and the principal amount of the proposed additional
lien) and (E) is not one of the 10 largest Mortgage Loans (considering any Cross-Collateralized Group as a single Mortgage Loan)
in the Mortgage Pool based on principal balance or (3) the related Serviced Mortgage Loan (including a Serviced Mortgage Loan
related to a Serviced Loan Combination) has a principal balance less than $10,000,000; provided that, for the avoidance
of doubt, notwithstanding any provision contained in the related Loan Documents to the contrary, no Rating Agency Confirmation
shall be required in connection with such waiver or grant of consent under any “due-on-encumbrance” provision if the
related Serviced Mortgage Loan satisfies the conditions set forth in clause (2) or clause (3) above of this sentence. Further,
neither the Master Servicer nor the Special Servicer may waive the rights of the lender or grant its consent under any “due-on-sale”
provision unless (1) the Master Servicer or the Special Servicer, as applicable (in each case, if it is the party processing the
related request pursuant to this Section 3.09(a)), shall have received a prior written Rating Agency Confirmation with
respect to such action, or (2) the related Serviced Mortgage Loan (including a Serviced Mortgage Loan related to a Serviced Loan


 






    	-219- 



     


    

 


Combination) (A) represents less than 5% of the principal balance of all of the Mortgage Loans in the Trust Fund, (B) has a principal
balance that is equal to or less than $35,000,000 and (C) is not one of the 10 largest Mortgage Loans (considering any Cross-Collateralized
Group as a single Mortgage Loan) in the Mortgage Pool based on principal balance or (3) the related Serviced Mortgage Loan (including
a Serviced Mortgage Loan related to a Serviced Loan Combination) has a principal balance less than $10,000,000; provided
that, for the avoidance of doubt, notwithstanding any provision contained in the related Loan Documents to the contrary, no Rating
Agency Confirmation shall be required in connection with such waiver or grant of consent under any “due-on-sale” provision
if the related Serviced Mortgage Loan satisfies the conditions set forth in clause (2) or clause (3) above of this sentence. For
the purposes of this Agreement, due-on-sale provisions shall include, without limitation, sales or transfers of Mortgaged Properties,
in full or in part, or the sale, transfer, pledge or hypothecation of direct or indirect interests in any Mortgagor or its owner,
in each case to the extent not permitted under the related Loan Documents, and due-on-encumbrance provisions shall include, without
limitation, any mezzanine/subordinate financing of any Mortgagor or any Mortgaged Property or any sale or transfer of preferred
equity in any Mortgagor or its owners, in each case to the extent not permitted under the related Loan Documents.


 


The
Master Servicer or the Special Servicer, as applicable (in each case, if it is the party processing the related request pursuant
to this Section 3.09(a)), shall notify in writing the Trustee, the Certificate Administrator, the Special Servicer or the
Master Servicer, as applicable, the Controlling Class Representative (prior to the occurrence and continuance of a Consultation
Termination Event), the Operating Advisor, the Rule 17g-5 Information Provider (for posting to the Rule 17g-5 Information Provider’s
Website pursuant to Section 12.13 of this Agreement) and, with respect to a Serviced Loan Combination, the related Serviced
Companion Loan Holder, of any assumption or substitution agreement executed pursuant to this Section 3.09(a) and shall
forward thereto a copy of such agreement, and shall also deliver to the Certificate Administrator (or a Custodian appointed by
it) an original of the recorded agreement relating to such assumption or substitution within 15 Business Days following the execution
and receipt thereof by the Master Servicer or the Special Servicer, as applicable.


 


In
connection with any request for a Rating Agency Confirmation from a Rating Agency pursuant to this Section 3.09(a),
the Master Servicer or the Special Servicer, as applicable (in each case, if it is the party processing the related request pursuant
to the first paragraph of this Section 3.09(a)), shall deliver a Review Package to the Rule 17g-5 Information Provider
for posting to the Rule 17g-5 Information Provider’s Website in accordance with Section 12.13 of this Agreement.


 


Further,
subject to the terms of the related Loan Documents and applicable law, the Master Servicer or the Special Servicer, as applicable
(in each case, if it is the party processing the related request pursuant to this Section 3.09(a)), shall use reasonable efforts
to cause all costs in connection with any assumption or encumbrance, including any arising from seeking a Rating Agency Confirmation,
to be paid by the related Mortgagor. To the extent not collected from the related Mortgagor after the use of such efforts, any
rating agency charges in connection with the foregoing shall be paid by the Master Servicer as a Property Advance (or as an Additional
Trust Fund Expense if such Property Advance would be a Nonrecoverable Advance).


 






    	-220- 



     


    

 


To
the extent not prohibited by the applicable Loan Documents and applicable law, the Master Servicer or Special Servicer, as applicable,
may charge the related Mortgagor a fee in connection with any enforcement or waiver contemplated in this subsection (a);
provided that any such fee shall be applied as if it were a Modification Fee and/or Assumption Fee, as applicable, pursuant
to the terms of this Agreement.


 


(b)         Nothing
in this Section 3.09 shall constitute a waiver of the Trustee’s right, as the mortgagee of record, to receive
notice of any assumption of a Mortgage Loan, any sale or other transfer of the related Mortgaged Property or the creation of any
lien or other encumbrance with respect to such Mortgaged Property.


 


(c)         In
connection with the taking of, or the failure to take, any action pursuant to this Section 3.09, neither the Master
Servicer nor the Special Servicer shall agree to modify, waive or amend, and no assumption or substitution agreement entered into
pursuant to Section 3.09(a) of this Agreement shall contain any terms that are different from, any term of any
Mortgage Loan or Serviced Companion Loan or the related Note, other than pursuant to Section 3.24 of this Agreement.


 


(d)         With
respect to any Serviced Mortgage Loan or Serviced Loan Combination which permits release of Mortgaged Properties through defeasance,
and to the extent consistent with the terms of the related Loan Documents:


 


(i)          Subject
to the consent rights of the Special Servicer and the Directing Holder and the process set forth in Sections 3.24 and 6.09
with respect to Major Decisions and Special Servicer Decisions, the Master Servicer shall process all defeasances of Serviced
Mortgage Loans and Serviced Loan Combinations in accordance with the terms of the related Loan Documents, and shall be entitled
to any defeasance fees paid relating thereto (provided that for the avoidance of doubt, any such defeasance fee shall not include
the Special Servicer’s portion of any Modification Fees or waiver fees in connection with a defeasance to which the Special
Servicer is entitled under this Agreement).


 


(ii)         In
the event such Serviced Mortgage Loan or Serviced Loan Combination requires that the Master Servicer on behalf of the Trustee
purchase the required “government securities” within the meaning of Section 2(a)(16) of the Investment Company
Act of 1940, or any other securities that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii), the Master Servicer,
an accommodation Mortgagor pursuant to clause (v) below or the Mortgagor shall, at the Mortgagor’s expense (to
the extent consistent with the related Loan Documents), purchase or cause the purchase of such obligations in accordance with
the terms of such Mortgage Loan or Serviced Loan Combination and deliver to the Master Servicer, in the case of the Mortgagor,
or in the case of the Master Servicer, hold the same on behalf of the Trust Fund and, if applicable, the related Serviced Companion
Loan Holder; provided that, subject to the related Loan Documents, the Master Servicer shall not accept the amounts paid
by the related Mortgagor to effect defeasance until acceptable “government securities” within the meaning of Section 2(a)(16)
of the Investment Company Act of 1940, or any other securities that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii) have
been identified, in each case which are acceptable as defeasance collateral under the then most recently published


 






    	-221- 



     


    

 


current
guidelines of the Rating Agencies. Notwithstanding the foregoing, with respect to each of the Mortgage Loans identified on Exhibit
Q to this Agreement (each, a “Retained Defeasance Rights and Obligations Mortgage Loan” and, collectively,
the “Retained Defeasance Rights and Obligations Mortgage Loans”), the related Mortgage Loan Seller or originator
has transferred to a third party or has retained the right to establish or designate the successor borrower and/or to purchase
or cause to be purchased the related defeasance collateral (“Retained Defeasance Rights and Obligations”).
In the event the Master Servicer receives notice of a defeasance request with respect to a Mortgage Loan that provides for Retained
Defeasance Rights and Obligations in the related Loan Documents, the Master Servicer shall provide, within five (5) business days
of receipt of such notice, written notice of such defeasance request to the related Mortgage Loan Seller or to the related Mortgage
Loan Seller’s assignee. Until such time as CCRE provides written notice to the contrary, the notice of a defeasance of a
Mortgage Loan with Retained Defeasance Rights and Obligations as to which CCRE is the related Mortgage Loan Seller shall be delivered
to Cantor Commercial Real Estate Lending, L.P., 110 East 59th Street, New York, New York 10022, Attention: Anthony Orso, fax number:
(212) 610-3623, with copies to General Counsel. Until such time as LCF provides written notice to the contrary, the notice of
a defeasance of a Mortgage Loan with Retained Defeasance Rights and Obligations as to which LCF is the related Mortgage Loan Seller
shall be delivered to 345 Park Avenue, 8th Floor, New York, New York 10154, Attention: Pamela McCormack, with electronic copies
to: Pamela McCormack (pamela.mccormack@laddercapital.com), Robert Perelman (robert.perelman@laddercapital.com), and David Traitel

of a Mortgage Loan with Retained Defeasance Rights and Obligations as to which GACC is the related Mortgage Loan Seller shall
be delivered to German American Capital Corporation, 60 Wall Street, New York, New York 10005, Attention: Lainie Kaye, with a
copy by electronic mail to lainie.kaye@db.com and to cmbs.requests@db.com. Until such time as Rialto provides written notice
to the contrary, the notice of a defeasance of a Mortgage Loan with Retained Defeasance Rights and Obligations as to which Rialto
is the related Mortgage Loan Seller shall be delivered to Rialto Mortgage Finance, LLC, 600 Madison Avenue, 12th Floor, New York,
New York 10022, Attention: Kenneth M. Gorsuch, Managing Director.


 


(iii)        The
Master Servicer shall require, to the extent the related Loan Documents grant the mortgagee discretion to so require, delivery
of an Opinion of Counsel (which shall be an expense of the related Mortgagor to the extent consistent with the related Loan Documents)
to the effect that the Trustee on behalf of the Certificateholders has a first priority security interest in the defeasance deposit
and the “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940,
or any other securities that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii), and the assignment thereof is valid
and enforceable; such opinion, together with any other certificates or documents to be required in connection with such defeasance
shall be in form and substance acceptable to the Master Servicer.


 


(iv)        The
Master Servicer shall obtain, to the extent the related Loan Documents grant the mortgagee discretion to so obtain, a certificate
(which shall be an expense of the related Mortgagor to the extent consistent with the related Loan Documents) from an


 






    	-222- 



     


    

 


Independent
certified public accountant certifying that the “government securities” within the meaning of Section 2(a)(16)
of the Investment Company Act of 1940, or any other securities that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii),
comply with the requirements of the related Loan Agreement or Mortgage.


 


(v)         To
the extent consistent with the related Loan Documents, prior to permitting release of any Mortgaged Properties through defeasance,
the Master Servicer shall (at the Mortgagor’s expense) obtain a Rating Agency Confirmation; provided that the Master Servicer
shall not be required to obtain such Rating Agency Confirmation from any Rating Agency to the extent that the Master Servicer
has delivered a defeasance certificate to such Rating Agency substantially in the form of Exhibit DD to this Agreement
for any Mortgage Loan that, at the time of such defeasance, is (x) not one of the ten largest Mortgage Loans by Stated Principal
Balance, (y) a Mortgage Loan with a Stated Principal Balance equal to or less than $35,000,000 and (z) a Mortgage Loan that
represents less than 5% of the Stated Principal Balance of all Mortgage Loans.


 


(vi)        If
the Mortgage Loan or Serviced Loan Combination permits the related Mortgagor or the lender or its designee to cause an accommodation
Mortgagor to assume such defeased obligations, the Master Servicer shall, or shall cause the Mortgagor to, establish at the Mortgagor’s
cost and expense (and shall use efforts consistent with the Servicing Standard to cause the related Mortgagor to consent to such
assumption) a special purpose bankruptcy-remote entity to assume such obligations, as to which the Trustee and the Certificate
Administrator has received a Rating Agency Confirmation (if such confirmation is required pursuant to the then most recently published
guidelines of the Rating Agencies).


 


(vii)       To
the extent consistent with the related Loan Documents, the Master Servicer shall require the related Mortgagor to pay all costs
and expenses incurred in connection with the defeasance of the related Mortgage Loan or Serviced Loan Combination. In the event
that the Mortgagor is not required to pay any such costs and expenses under the terms of the Loan Documents, such costs and expenses
shall be Additional Trust Fund Expenses.


 


(viii)      In
no event shall the Master Servicer have liability to any party hereto or beneficiary hereof for obtaining a Rating Agency Confirmation
(or conditioning approval of defeasance on the delivery of a Rating Agency Confirmation) or for imposing conditions to approval
of a defeasance on the satisfaction of conditions that are consistent with the Servicing Standard but are not required under Rating
Agency guidelines (provided that this shall not protect the Master Servicer from any liability that may be imposed as a
result of the violation of applicable law or the Loan Documents).


 


(ix)         The
Master Servicer may accept as defeasance collateral any “government security,” within the meaning of Treasury Regulation’s
Section 1.860G-(2)(a)(8)(ii), notwithstanding any more restrictive requirements in the Loan Documents; provided, that the Master
Servicer has received an Opinion of Counsel that acceptance of such defeasance collateral will not endanger the status of either
Trust REMIC as a REMIC or result in the imposition of a tax upon either Trust REMIC or the Trust Fund (including but not limited


 






    	-223- 



     


    

 


to the tax on “prohibited transactions” as defined in Section 860F(a)(2) of the Code and the tax on contributions
to a REMIC set forth in Section 860G(d) of the Code, but not including the tax on “net income from foreclosure property”
as set forth in Section 860G(c) of the Code).


 


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


 


Section 3.10           Appraisal
Reductions; Calculation and allocation of Collateral Deficiency Amounts; Realization Upon Defaulted Loans.


 


(a)         Promptly
upon the occurrence of an Appraisal Reduction Event with respect to a Serviced Loan, the Special Servicer shall use reasonable
efforts to obtain an updated Appraisal of the related Mortgaged Property, the costs of which shall be advanced by, and reimbursable
to, the Master Servicer as a Property Advance (or shall be an expense of the Trust Fund and paid by the Master Servicer out of
the Collection Account if such Property Advance would be a Nonrecoverable Advance); provided, however, that the
Special Servicer shall not be required to obtain an updated Appraisal of any Mortgaged Property with respect to which there exists
an Appraisal which is less than nine months old unless the Special Servicer determines in accordance with the Servicing Standard
that such previously obtained Appraisal is materially inaccurate. With respect to any Serviced Loan for which an Appraisal Reduction
Event has occurred and still exists, the Special Servicer shall obtain annual letter updates to any updated Appraisal. Any Appraisal
prepared in order to determine the Appraisal Reduction Amount with respect to a Serviced Loan Combination shall be delivered by
the Special Servicer, upon request, to each related Serviced Companion Loan Holder.


 


As
of the first Determination Date following a Serviced Mortgage Loan becoming an AB Modified Loan, the Special Servicer shall calculate
whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan, taking into account the most recent Appraisal
obtained by the Special Servicer with respect to such Serviced Mortgage Loan, and all other information relevant to a Collateral
Deficiency Amount determination. The Master Servicer shall provide (via electronic delivery) the Special Servicer with information
in its possession that is reasonably required to calculate or recalculate any Collateral Deficiency Amount pursuant to the definition
thereof using reasonable efforts to deliver such information within four (4) Business Days of the Special Servicer’s reasonable
written request. Upon obtaining actual knowledge or


 






    	-224- 



     


    

 


receipt of notice by the Master Servicer that an Outside Serviced Mortgage
Loan has become an AB Modified Loan, the Master Servicer shall (i) promptly request from the related Outside Servicer, Outside
Special Servicer and Outside Trustee the most recent appraisal with respect to such AB Modified Loan, in addition to all other
information reasonably required by the Master Servicer to calculate whether a Collateral Deficiency Amount exists with respect
to such AB Modified Loan, and (ii) as of the first Determination Date following receipt by the Master Servicer of the appraisal
and any other information set forth in the immediately preceding clause (i) that the Master Servicer reasonably expects to receive
(and does receive within a reasonable period of time) and reasonably believes is necessary to perform such calculation, calculate
whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan, taking into account the most recent appraisal
obtained by the Master Servicer from the Outside Servicer, Outside Special Servicer or Outside Trustee, as the case may be, with
respect to such Outside Serviced Mortgage Loan, and all other information relevant to a Collateral Deficiency Amount determination.
In connection with its calculation of a Collateral Deficiency Amount with respect to an Outside Serviced Mortgage Loan that has
become an AB Modified Loan, the Master Servicer shall be entitled to conclusively rely on any appraisal or other information received
from the related Outside Servicer, Outside Special Servicer or Outside Trustee. The Master Servicer shall notify the Special Servicer
and the Certificate Administrator of any Collateral Deficiency Amount calculated by the Master Servicer with respect to an Outside
Serviced Mortgage Loan that has become an AB Modified Loan. The Special Servicer and the Certificate Administrator shall be entitled
to conclusively rely on any Collateral Deficiency Amounts calculated by the Master Servicer with respect to an Outside Serviced
Mortgage Loan. Upon any other party to this Agreement obtaining knowledge or receipt of notice that an Outside Serviced Mortgage
Loan has become an AB Modified Loan, such party shall promptly notify the Master Servicer thereof. Neither the Trustee nor the
Certificate Administrator shall calculate or verify any Collateral Deficiency Amount. For the avoidance of doubt, the Master Servicer
shall only calculate Collateral Deficiency Amounts with respect to Outside Serviced Mortgage Loans.


 


The
Certificate Balance of each Class of applicable Principal Balance Certificates shall be notionally reduced (solely for purposes
of determining the identity of the Non-Reduced Certificates and the Controlling Class, as well as the occurrence of a Control
Termination Event, and, to the extent expressly set forth herein, for purposes of allocating and/or exercising Voting Rights in
connection with certain circumstances involving the termination of certain parties hereto) as of any date of determination to
the extent of the Appraisal Reduction Amount(s) allocated to such Class on the preceding Distribution Date. The aggregate Appraisal
Reduction Amount for any Distribution Date shall be applied to notionally reduce the Certificate Balances of the following Classes
of Certificates in the following order of priority: first, to the Class J-RR Certificates; second, to the Class
H-RR Certificates; third, to the Class G-RR Certificates; fourth, to the Class F-RR Certificates; fifth,
to the Class E-RR Certificates; sixth, to the Class D Certificates; seventh, to the Class C Certificates;
eighth, to the Class B Certificates; ninth, to the Class A-S Certificates; and finally, pro rata to the (i) Class A-1
Certificates, (ii) Class A-2 Certificates, (iii) Class A-3 Certificates, (iv) Class A-4 Certificates,
and (v) Class A-AB Certificates, based on their respective Certificate Balances (provided in each case that no Certificate
Balance in respect of any such Class may be notionally reduced below zero). In addition, as of any date of determination for purposes
of determining the Controlling Class or the occurrence of a Control Termination Event, and after taking into account the allocations
contemplated by the prior sentence, the Collateral Deficiency Amounts shall be applied to


 






    	-225- 



     


    

 


notionally reduce the Certificate Balances
of each Class of the Control Eligible of Certificates in the following order of priority (in each case after taking into account
any Appraisal Reduction Amounts allocated thereto): first, to the Class J-RR Certificates; second, to the Class
H-RR Certificates; third, to the Class G-RR Certificates; fourth, to the Class F-RR Certificates; and fifth,
to the Class E-RR Certificates (provided in each case that no Certificate Balance in respect of any such Class may be notionally
reduced below zero). For the avoidance of doubt, for purposes of determining the Controlling Class or the occurrence of a Control
Termination Event, any Class of Control Eligible Certificates shall be allocated both applicable Appraisal Reduction Amounts and
applicable Collateral Deficiency Amounts (the sum of which shall constitute the applicable Cumulative Appraisal Reduction Amount),
in accordance with the preceding two sentences.


 


With
respect to any Appraisal Reduction Amount calculated for the purposes of determining the Non-Reduced Certificates or, to the extent
expressly set forth herein, for the purposes of allocating and/or exercising Voting Rights in connection with certain circumstances
involving the termination of certain parties hereto, and with respect to any Appraisal Reduction Amount or Collateral Deficiency
Amount calculated for purposes of determining the Controlling Class or the occurrence of a Control Termination Event, the appraised
value of the related Mortgaged Property shall be determined on an “as-is” basis.


 


Each
of the Master Servicer and the Special Servicer (in each case, to the extent any such amount is required to be calculated by it)
shall promptly notify the other such party and the Certificate Administrator of the determination of (i) any Appraisal Reduction
Amount, (ii) any Collateral Deficiency Amount, and (iii) any resulting Cumulative Appraisal Reduction Amount by providing such
information in the CREFC® Appraisal Reduction Template, and the Certificate Administrator shall promptly post notice
of the determination of any such Appraisal Reduction Amount, Collateral Deficiency Amount and/or Cumulative Appraisal Reduction
Amount, as applicable, on the Certificate Administrator’s website.


 


Any
Appraisal Reduction Amounts with respect to each Serviced Loan Combination shall be allocated, first, to any related Serviced
Subordinate Companion Loan (up to the outstanding principal balance thereof), and then, to the related Serviced Mortgage Loan
and any related Serviced Pari Passu Companion Loan(s), on a pro rata and pari passu basis in accordance with the respective outstanding
principal balances of such related Serviced Mortgage Loan and the related Serviced Pari Passu Companion Loan.


 


The
Holders of Certificates representing the majority of the Certificate Balance of the most senior Class of Control Eligible Certificates
whose Certificate Balance is notionally reduced to less than 25% of the initial Certificate Balance of that Class as a result
of an allocation of an Appraisal Reduction Amount or Collateral Deficiency Amount in respect of such Class (such Class, an “Appraised-Out
Class”) shall have the right to challenge the Special Servicer’s Appraisal Reduction Amount determination or Collateral
Deficiency Amount determination and, at their sole expense, obtain a second Appraisal of any Serviced Loan for which an Appraisal
Reduction Event has occurred or as to which there exists a Collateral Deficiency Amount (such Holders, the “Requesting
Holders”). The Requesting Holders shall cause the Appraisal to be prepared on an “as-is” basis by an Appraiser,
and the Appraisal must be reasonably acceptable to the Special Servicer in accordance with the Servicing Standard. The Requesting
Holders shall provide the Special Servicer with notice of their intent to challenge the Special Servicer’s Appraisal Reduction


 






    	-226- 



     


    

 


Amount determination or Collateral Deficiency Amount determination within 10 days of the Requesting Holders’ receipt
of written notice of the determination of such Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable.


 


An
Appraised-Out Class shall be entitled to continue to exercise the rights of the Controlling Class until 10 days following
its receipt of written notice of the determination of an Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable,
unless the Requesting Holders provide written notice of their intent to challenge such Appraisal Reduction Amount or Collateral
Deficiency Amount to the Special Servicer and the Certificate Administrator within such 10-day period pursuant to the immediately
preceding paragraph. If the Requesting Holders provide such notice, then the Appraised-Out Class shall be entitled to continue
to exercise the rights of the Controlling Class until the earliest of (i) 120 days following the related Appraisal Reduction
Event or receipt of written notice of a Collateral Deficiency Amount, as applicable, unless the Requesting Holders provide the
second appraisal within such 120-day period, (ii) the determination by the Special Servicer (described below) that a recalculation
of the Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable, is not warranted or that such recalculation
does not result in the Appraised-Out Class remaining the Controlling Class and (iii) the occurrence of a Consultation Termination
Event. After the Appraised-Out Class is no longer entitled to exercise the rights of the Controlling Class, the rights of the
Controlling Class shall be exercised by the Class of Control Eligible Certificates immediately senior to such Appraised-Out Class,
if any, unless a recalculation results in the reinstatement of the Appraised-Out Class as the Controlling Class.


 


In
addition to the foregoing, the Holders of Certificates representing the majority of the Certificate Balance of any Appraised-Out
Class shall have the right, at their sole expense, to require the Special Servicer to order an additional Appraisal of any Serviced
Loan for which an Appraisal Reduction Event has occurred or as to which a Collateral Deficiency Amount exists if an event has
occurred at or with regard to the related Mortgaged Property or Mortgaged Properties that would have a material effect on its
appraised value, and the Special Servicer shall use its reasonable efforts, in accordance with the Servicing Standard, to obtain
such Appraisal within 30 days from receipt of such Holders’ written request and shall use its reasonable efforts, in
accordance with the Servicing Standard, to obtain an Appraisal that is prepared on an “as-is” basis by an Appraiser;
provided that the Special Servicer shall not be required to obtain such Appraisal if the Special Servicer determines in
accordance with the Servicing Standard that no events at or with regard to the related Mortgaged Property or Mortgaged Properties
have occurred that would have a material effect on such appraised value of the related Mortgaged Property or Mortgaged Properties.


 


Upon
receipt of an Appraisal provided by, or requested by, Holders of an Appraised-Out Class pursuant to this Section and any other
information reasonably requested by the Special Servicer from the Master Servicer reasonably required to calculate or recalculate
the Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable, the Special Servicer shall determine, in accordance
with the Servicing Standard, whether, based on its assessment of such additional Appraisal, any recalculation of the Appraisal
Reduction Amount or Collateral Deficiency Amount, as applicable, is warranted and, if so warranted, shall recalculate such Appraisal
Reduction Amount or Collateral Deficiency Amount based upon such additional Appraisal. If required by any such recalculation,
the Appraised-Out Class shall be reinstated as


 






    	-227- 



     


    

 


the Controlling Class. The Special Servicer shall promptly deliver notice to the
Certificate Administrator of any such determination and recalculation, and the Certificate Administrator shall promptly post such
notice to the Certificate Administrator’s Website.


 


Appraisals
that are permitted to be presented by, or obtained by the Special Servicer at the request of, Holders of an Appraised-Out Class
shall be in addition to any Appraisals that the Special Servicer may otherwise be required to obtain in accordance with the Servicing
Standard or this Agreement without regard to any appraisal requests made by any Holder of an Appraised-Out Class.


 


(b)          In
connection with any foreclosure, enforcement of the Loan Documents or other acquisition, the Master Servicer in accordance with
Section 3.20 of this Agreement shall pay the out-of-pocket costs and expenses in any such proceedings as a Property
Advance unless the Master Servicer determines, in accordance with the Servicing Standard, that such Advance would constitute a
Nonrecoverable Advance (in which case such costs shall be an expense of the Trust Fund and paid by the Master Servicer out of
the Collection Account). The Master Servicer shall be entitled to reimbursement of Advances (with interest at the Advance Rate)
made pursuant to the preceding sentence to the extent permitted by Section 3.06(a)(ii) of this Agreement.


 


Subject
to Section 3.21 of this Agreement, if the Special Servicer elects to proceed with a non-judicial foreclosure in accordance
with the laws of the state where the Mortgaged Property is located, the Special Servicer shall not be required to pursue a deficiency
judgment against the related Mortgagor or any other liable party if the laws of the state do not permit such a deficiency judgment
after a non-judicial foreclosure or if the Special Servicer determines, in accordance with the Servicing Standard, that the likely
recovery if a deficiency judgment is obtained will not be sufficient to warrant the cost, time, expense and/or exposure of pursuing
the deficiency judgment and such determination is evidenced by an Officer’s Certificate delivered to the Trustee, the Certificate
Administrator, any related Outside Controlling Note Holder, the Operating Advisor and (prior to the occurrence and continuance
of a Consultation Termination Event) the Controlling Class Representative.


 


In
the event that title to any Mortgaged Property (other than any Mortgaged Property related to an Outside Serviced Mortgage Loan)
is acquired in foreclosure or by deed-in-lieu of foreclosure, the deed or certificate of sale shall be issued to the Trustee,
to a co-trustee or to its nominee (which shall not include the Master Servicer but may be a single member limited liability company
owned by the Trust and managed by the Special Servicer) or a separate trustee or co-trustee on behalf of the Trustee as holder
of the Lower-Tier Regular Interests and on behalf of the holders of the Certificates and, if applicable, and the related Serviced
Companion Loan Holders. Notwithstanding any such acquisition of title and cancellation of the related Serviced Mortgage Loan,
the related Serviced Mortgage Loan shall (except for purposes of Section 9.01) be considered to be an REO Mortgage
Loan held in the Trust Fund until such time as the related REO Property shall be sold by the Trust Fund and shall be reduced only
by collections net of expenses.





 






    	-228- 



     


    

 


(c)         Notwithstanding
any provision to the contrary, the Special Servicer shall not acquire for the benefit of the Trust Fund any personal property
pursuant to this Section 3.10 unless either:


 


(i)          such
personal property is (in the good faith judgment of the Special Servicer) incident to real property (within the meaning of
Code Section 856(e)(1)) so acquired by the Special Servicer for the benefit of the Trust Fund; or


 


(ii)         the
Special Servicer shall have requested and received an Opinion of Counsel (which opinion shall be an expense of the Trust Fund)
to the effect that the holding of such personal property by the Trust Fund will not cause the imposition of a tax on a Trust REMIC
under the REMIC Provisions or cause either Trust REMIC to fail to qualify as a REMIC for federal income tax purposes or cause
the Grantor Trust to fail to qualify as a grantor trust for federal income tax purposes at any time that any Certificate is outstanding.


 


(d)         Notwithstanding
any provision to the contrary in this Agreement, neither the Special Servicer nor the Master Servicer shall, on behalf of the
Trust Fund or, if applicable, the related Serviced Companion Loan Holder, obtain title to any direct or indirect partnership or
membership interest or other equity interest in any Mortgagor pledged pursuant to any pledge agreement, unless the Master Servicer
or the Special Servicer shall have requested and received an Opinion of Counsel (which opinion shall be an expense of the Trust
Fund) to the effect that the holding of such partnership or membership interest or other equity interest by the Trust Fund will
not cause the imposition of a tax on a Trust REMIC under the REMIC Provisions or cause either Trust REMIC to fail to qualify as
a REMIC for federal income tax purposes or cause the Grantor Trust to fail to qualify as a grantor trust for federal income tax
purposes at any time that any Certificate is outstanding.


 


(e)         Notwithstanding
any provision to the contrary contained in this Agreement, the Special Servicer shall not, on behalf of the Trust Fund or, if
applicable, the related Serviced Companion Loan Holders, obtain title to a Mortgaged Property as a result of foreclosure or by
deed-in-lieu of foreclosure or otherwise, obtain title to any direct or indirect partnership or membership interest in any Mortgagor
pledged pursuant to a pledge agreement and thereby be the beneficial owner of a Mortgaged Property, and shall not otherwise acquire
possession of, or take any other action with respect to, any Mortgaged Property if, as a result of any such action, the Custodian,
the Trustee, the Certificate Administrator or the Trust Fund or the Certificateholders or, if applicable, the related Serviced
Companion Loan Holders, would be considered to hold title to, or be a “mortgagee-in-possession” of, or to be an “owner”
or “operator” of such Mortgaged Property within the meaning of the Comprehensive Environmental Response, Compensation
and Liability Act of 1980, as amended from time to time, or any comparable law, unless the Special Servicer has previously determined
in accordance with the Servicing Standard, based on an updated environmental assessment report prepared by an Independent Person
who regularly conducts environmental audits, that:


 


(i)          such
Mortgaged Property is in compliance with applicable environmental laws or, if not, after consultation with an environmental consultant,
that it would be in the best economic interest of the Trust Fund and any related Serviced Companion Loan Holder


 






    	-229- 



     


    

 


(as a collective
whole) to take such actions as are necessary to bring such Mortgaged Property in compliance therewith; and


 


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


 


In
the event that the environmental assessment first obtained by the Special Servicer with respect to a Mortgaged Property indicates
that such Mortgaged Property may not be in compliance with applicable environmental laws or that Hazardous Materials may be present
but does not definitively establish such fact, the Special Servicer shall cause such further environmental tests to be conducted
by an Independent Person who regularly conducts such tests as the Special Servicer shall deem prudent to protect the interests
of Certificateholders and any related Serviced Companion Loan Holder. Any such tests shall be deemed part of the environmental
assessment obtained by the Special Servicer for purposes of this Section 3.10.


 


In
the event that the Special Servicer seeks to obtain title to a Mortgaged Property on behalf of the Trust Fund and any related
Serviced Companion Loan Holder, the Special Servicer may, in its discretion, establish a single member limited liability company
with the Trust Fund and any related Serviced Companion Loan Holder as the sole owner to hold title to such Mortgaged Property.


 


(f)          The
environmental assessment contemplated by Section 3.10(e) of this Agreement shall be prepared within three months
of the determination that such assessment is required by any Independent Person who regularly conducts environmental audits for
purchasers of commercial property where the Mortgaged Property is located, as determined by the Special Servicer in a manner consistent
with the Servicing Standard and, if applicable, any secured creditor impaired property policy issued on or prior to the Closing
Date with respect to any Mortgage Loan (including that the environmental assessment identify any potential pollution conditions
(as defined in the environmental insurance policy) with respect to the related Mortgaged Property). The Master Servicer shall
advance the cost of preparation of such environmental assessments unless the Master Servicer determines, in accordance with the
Servicing Standard, that such Advance would be a Nonrecoverable Advance (in which case such costs shall be an expense of the Trust
Fund and paid by the Master Servicer out of the Collection Account). The Master Servicer shall be entitled to reimbursement of
Advances (with interest at the Advance Rate) made pursuant to the preceding sentence in the manner set forth in Section 3.06
of this Agreement. Copies of any environmental assessment prepared pursuant to Section 3.10(e) of this Agreement shall
be provided to the Holder of any Principal Balance Certificates and any related Serviced Companion Loan Holder upon written request
to the Special Servicer.


 






    	-230- 



     


    

 


(g)         If
the Special Servicer determines pursuant to Section 3.10(e)(i) of this Agreement that a Mortgaged Property is
not in compliance with applicable environmental laws, but that it is in the best economic interest of the Trust Fund and any related
Serviced Companion Loan Holder, as a collective whole as if the Trust Fund and any related Serviced Companion Loan Holder constituted
a single lender (and, in the case of a Serviced AB Loan Combination, taking into account the subordinate nature of any related
Subordinate Companion Loan), to take such actions as are necessary to bring such Mortgaged Property in compliance therewith, or
if the Special Servicer determines pursuant to Section 3.10(e)(ii) of this Agreement that the circumstances referred
to therein relating to Hazardous Materials are present, but that it is in the best economic interest of the Trust Fund and any
related Serviced Companion Loan Holder, as a collective whole as if the Trust Fund and any related Serviced Companion Loan Holder
constituted a single lender (and, in the case of a Serviced AB Loan Combination, taking into account the subordinate nature of
any related Subordinate Companion Loan), to take such action with respect to the containment, clean-up or remediation of Hazardous
Materials affecting such Mortgaged Property as is required by law or regulation, then the Special Servicer shall take such action
as it deems to be in the best economic interest of the Trust Fund and any related Serviced Companion Loan Holder, as a collective
whole as if the Trust Fund and any related Serviced Companion Loan Holder constituted a single lender (and, in the case of a Serviced
AB Loan Combination, taking into account the subordinate nature of any related Subordinate Companion Loan). The Master Servicer
shall pay the cost of any such compliance, containment, clean-up or remediation from the Collection Account.


 


(h)         The
Special Servicer shall notify the Master Servicer of any abandoned and/or foreclosed properties which require reporting to the
IRS and shall provide the Master Servicer with all information regarding forgiveness of indebtedness and required to be reported
with respect to any Mortgage Loan or Serviced Companion Loan which is abandoned or foreclosed and the Master Servicer shall report
to the IRS and the related Mortgagor, in the manner required by applicable law, such information and the Master Servicer shall
report, via IRS Form 1099C, all forgiveness of indebtedness to the extent such information has been provided to the Master
Servicer by the Special Servicer. Upon request, the Master Servicer shall deliver a copy of any such report to the Trustee, the
Certificate Administrator and, if affected, to any related Serviced Companion Loan Holder.


 


Section 3.11           Trustee,
Certificate Administrator and Custodian to Cooperate; Release of Mortgage Files. Upon the payment in full of any
Mortgage Loan or Serviced Loan Combination or the receipt by the Master Servicer or the Special Servicer of a notification
that payment in full has been escrowed in a manner customary for such purposes, the Master Servicer or the Special Servicer
shall immediately notify the Trustee, the Certificate Administrator and the Custodian and, if affected, the related Serviced
Companion Loan Holder by delivery of a certification (which certification shall include a statement to the effect that all
amounts received or to be received in connection with such payment which are required to be deposited in the Collection
Account pursuant to Section 3.05 of this Agreement have been or will be so deposited) of a Servicing Officer and
shall request delivery to it of the Mortgage File. No expenses incurred in connection with any instrument of satisfaction or
deed of reconveyance shall be chargeable to the Trust Fund.


 






    	-231- 



     


    

 


From
time to time upon request of the Master Servicer or Special Servicer and delivery to the Certificate Administrator of a Request
for Release, the Certificate Administrator (or a Custodian appointed by it) shall promptly release the Mortgage File (or any portion
thereof) designated in such Request for Release to the Master Servicer or Special Servicer, as applicable. Upon return of the
foregoing to the Certificate Administrator (or a Custodian appointed by it) or, in the event of a liquidation or conversion of
the Mortgage Loan or Serviced Loan Combination into an REO Property, receipt by the Trustee and the Certificate Administrator
of a certificate of a Servicing Officer stating that such Mortgage Loan or Serviced Loan Combination was liquidated and that all
amounts received or to be received in connection with such liquidation which are required to be deposited into the Collection
Account have been so deposited, or that such Mortgage Loan or Serviced Loan Combination has become an REO Property, the Certificate
Administrator shall deliver (or cause any Custodian appointed by it to deliver) a copy of the Request for Release to the Master
Servicer or Special Servicer, as applicable.


 


Within
three (3) Business Days, after receipt of written certification of a Servicing Officer, the Trustee shall execute and deliver
to the Special Servicer any court pleadings, requests for trustee’s sale or other documents prepared by the Special Servicer,
its agents or attorneys and reasonably acceptable to the Trustee, necessary to the foreclosure or trustee’s sale in respect
of a Mortgaged Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Loan or Serviced
Loan Combination, or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by the Loan Documents
or otherwise available at law or in equity. Each such certification shall include a request that such pleadings or documents be
executed by the Trustee and a statement as to the reason such documents or pleadings are required, and that the execution and
delivery thereof by the Trustee will not invalidate or otherwise affect the lien of the Mortgage or other security agreement,
except for the termination of such a lien upon completion of the foreclosure or trustee’s sale.


 


If
from time to time, pursuant to the terms of the Co-Lender Agreement and the applicable Outside Servicing Agreement related to
an Outside Serviced Mortgage Loan, and as appropriate for enforcing the terms of, or otherwise properly servicing, such Outside
Serviced Mortgage Loan, the related Outside Servicer, the related Outside Special Servicer or other similar party requests delivery
to it of the original Note for such Outside Serviced Mortgage Loan, then such party shall deliver a Request for Release in the
form of Exhibit C attached hereto to the Certificate Administrator and the Certificate Administrator shall release
(or cause any Custodian appointed by it to release) such original Note to the requesting party or its designee. In connection
with the release of the original Note for an Outside Serviced Mortgage Loan in accordance with the preceding sentence, the Certificate
Administrator (or a Custodian appointed by it) shall obtain such documentation as is appropriate to evidence the holding by the
related Outside Servicer, the related Outside Special Servicer or such other similar party, as the case may be, of such original
Note as custodian on behalf of and for the benefit of the Trustee.


 


Section 3.12           Servicing
Fees, Trustee/Certificate Administrator Fees and Special Servicing Compensation.

Compensation”), (i) 100% of any Excess Modification Fees with respect to a modification, waiver, extension or
amendment of a Performing Serviced Loan consented to by the Master Servicer pursuant to Section 3.24 of this Agreement
that did not require the approval of the Special Servicer, (ii) 50% of any Excess Modification Fees with respect to a
modification, waiver, extension or amendment of a Performing Serviced Loan consented to by the Special Servicer pursuant to Section
3.24 of this Agreement (whether or not the Special Servicer elects to handle any related processing), (iii) 100% of
any defeasance fee received in connection with a defeasance of a Serviced Loan as contemplated under Section 3.09 of
this Agreement (provided that for the avoidance of doubt, any such defeasance fee shall not include the Special

Servicer is entitled under this Agreement), (iv) 100% of any Assumption Fees with respect to a Performing Serviced Loan

the extent such amount is not required to be included in any Compensating Interest Payment, in each case to the extent

Agreement, (vii) 100% of Ancillary Fees (other than (A) fees for insufficient or returned checks and (B) beneficiary
statement charges) actually received from Mortgagors with respect to the accounts held by the Master Servicer pursuant to

Charges accrued during the period such Serviced Loan is a Specially Serviced Loan (provided that for the avoidance of

    	-233- 



     


    

 


Servicer shall not be entitled to apply or retain any amounts described in clauses (i) through (v) above as additional compensation
with respect to a specific Mortgage Loan or Serviced Loan Combination, as applicable, with respect to which a default or event
of default thereunder has occurred and is continuing unless and until such default or event of default has been cured (or has
been waived in accordance with the terms of this Agreement) and all delinquent amounts required to have been paid by the Mortgagor,
Advance Interest Amounts and Additional Trust Fund Expenses (other than Special Servicing Fees, Workout Fees and Liquidation Fees) both
(x) due with respect to such Mortgage Loan or Serviced Loan Combination, as applicable, and (y) in the case of expense
items, that arose within the last 12 months, have been paid. The Master Servicer shall also be entitled pursuant to, and
to the extent provided for in Sections 3.06(a)(iii), Section 3.06(A) and Section 3.07(b),
to withdraw from the Collection Account and the Loan Combination Custodial Accounts and to receive from any Mortgagor Accounts
(to the extent not payable to the related Mortgagor under a Mortgage Loan or Serviced Loan Combination or applicable law) any

Combination Custodial Account and Mortgagor Accounts (to the extent consistent with the related Loan Documents), shall be paid
to the Master Servicer as additional servicing compensation and interest or other income earned on funds in any REO Account shall
be payable to the Special Servicer. In addition, the Master Servicer shall be entitled to charge and retain reasonable review
fees in connection with any Mortgagor request with respect to any Performing Serviced Loan that either does not relate to a Major
Decision or a Special Servicer Decision or relates to a Major Decision or Special Servicer Decision that is being processed by
the Master Servicer with the mutual agreement of the Special Servicer, to the extent such fees are (i) not inconsistent with the
related Loan Documents, (ii) in accordance with the Servicing Standard and (iii) actually paid by or on behalf of the related
Mortgagor.


 


For
the avoidance of doubt, with respect to any Excess Modification Fee, Assumption Fee, Consent Fee or other fee with respect to
a Performing Serviced Loan that is required to be split between the Master Servicer and the Special Servicer pursuant to the terms
of this Agreement, the Master Servicer and the Special Servicer shall each have the right in its sole discretion, but not any
obligation, to reduce or elect not to charge its respective percentage interest in any such fee; provided, however (x) neither
the Master 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 Master 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 Master 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 Master Servicer had charged a fee and the Master Servicer shall not be entitled to
any of such fee charged by the Special Servicer. The foregoing provisions of this paragraph shall only apply to Performing Serviced
Loans and, subject to the other terms of this Agreement, shall not prohibit any waiver or reduction by the Special Servicer of
any fee payable by the Mortgagor with respect to any Specially Serviced Loan.

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), in either case, to any Qualified Institutional Buyer or Institutional Accredited

(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 CC-1 to this Agreement, and (iii) the prospective transferee
shall have delivered to Midland Loan Services, a Division of PNC Bank, National Association and the Depositor a certificate
substantially in the form attached as Exhibit CC-2 to this Agreement. None of the Depositor, the Trustee, the
Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or the Certificate Registrar is
obligated to register or qualify an Excess Servicing Fee Right under the Securities Act or any other securities law or to
take any action not otherwise required under this Agreement to permit the transfer, sale, pledge or assignment of an Excess

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 Midland Loan Services, a Division of PNC Bank, 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 Underwriters, the Initial Purchasers, the Certificate
Administrator, the Trustee, the Custodian, the Master Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Certificate Registrar 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 any
information received in connection with its acquisition and holding of such Excess Servicing Fee Right 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. From time to time
following any transfer, sale, pledge or assignment of an Excess Servicing Fee Right, the Person then acting as the Master
Servicer shall pay, out of each amount paid to such Master Servicer as Servicing Fees with respect to each related Mortgage
Loan or REO Mortgage Loan, as the case may be, 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 the Master Servicer, in each case in
accordance with payment instructions provided by such holder in writing to the Master 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 Certificate Administrator, the Certificate Registrar, the Operating Advisor, the Asset
Representations Reviewer, the Depositor, the Special Servicer, the Trustee or the Custodian shall have any obligation
whatsoever regarding payment of the Excess Servicing Fee or the assignment or transfer of the Excess Servicing Fee
Right.


 


Except
as otherwise provided herein, the Master Servicer shall pay all expenses incurred by it in connection with its servicing activities
hereunder, including all fees of any Sub-Servicers retained by it.

The
Master Servicer will not be entitled to retain any portion of Excess Interest paid on any Mortgage Loan. Notwithstanding anything
herein to the contrary, in the case of a Serviced Loan Combination, in no event shall Servicing Fees with respect to the related
Mortgage Loan (including an REO Mortgage Loan) be payable out of payments and other collections with respect to the related Serviced
Pari Passu Companion Loan(s), and in no event shall Servicing Fees with respect to the related Serviced Pari Passu Companion Loan(s)
(including an REO Companion Loan) be payable out of payments and other collections with respect to the related Mortgage Loan or
the Mortgage Pool. In addition, with respect to any Serviced Subordinate Companion Loan, in no event shall Servicing Fees with
respect to such Serviced Subordinate Companion Loan (including an REO Companion Loan) be payable out of payments and other collections
with respect to any related Serviced Pari Passu Companion Loan(s), the related Mortgage Loan or the Mortgage Pool. This paragraph
is in no way intended to limit the rights, if any, of the Master Servicer under the related Co-Lender Agreement to seek payment
of unpaid Servicing Fees with respect to any Serviced Companion Loan from the related Serviced Companion Loan Holder.


 


(b)          As
compensation for its activities hereunder, on each Distribution Date the Trustee shall be entitled with respect to each Mortgage
Loan to its portion of the Trustee/Certificate Administrator Fee, and the Certificate Administrator shall be entitled with respect
to each Mortgage Loan to its portion of the Trustee/Certificate Administrator Fee. The Certificate Administrator shall pay the
Trustee the Trustee’s portion of the Trustee/Certificate Administrator Fee. Except as otherwise provided herein, the Trustee/Certificate
Administrator Fee includes all routine expenses of the Trustee, the Certificate Registrar, the Paying Agent, the Certificate Administrator
and the Authenticating Agent. Each of the Trustee’s and Certificate Administrator’s rights to the Trustee/Certificate
Administrator Fee 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.


 


(c)          As
compensation for its activities hereunder, the Special Servicer shall be entitled with respect to each Specially Serviced Loan
(including each Serviced Companion Loan that is included as part of each Serviced Loan Combination) in respect of each Interest
Accrual Period to the Special Servicing Fee, which shall be payable from amounts on deposit in the Collection Account and/or,
in the case of a Serviced Loan Combination or portion thereof, the related Loan Combination Custodial Account as set forth in
Section 3.06(a) and Section 3.06A. The Special Servicer’s rights to the Special Servicing Fee may
not be transferred in whole or in part except in connection with the transfer of all of the Special Servicer’s responsibilities
and obligations under this Agreement. In addition, the Special Servicer shall be entitled to receive, as additional servicing
compensation (the following items, collectively, the “Additional Special Servicing Compensation”): (i) 50%
of any Excess Modification Fees with respect to a modification, waiver, extension or amendment of a Performing Serviced Loan consented
to by the Special Servicer pursuant to Section 3.24 of this Agreement (whether or not the Special Servicer elects
to handle any related processing); (ii) 100% of any Excess Modification Fees with respect to a modification, waiver, extension
or amendment of a Specially Serviced Loan consented to by the Special Servicer pursuant to Section 3.24 of this Agreement;
(iii) 100% of any Assumption Fees with respect to a Specially Serviced Loan; (iv) 50% of any Assumption Fees with respect
to a Performing Serviced Loan involving a transaction described in the definition of “Assumption Fees” consented to
by the Special Servicer (whether or not the Special Servicer elects to handle any related processing); (v) 100% of Ancillary
Fees (other than (A) fees for insufficient or returned


 






    	-236- 



     


    

 


checks and (B) beneficiary statement charges) actually received from Mortgagors
with respect to accounts held by the Special Servicer pursuant to this Agreement or the related Loan Documents, including the
Loss of Value Reserve Fund and any REO Accounts; (vi) 100% of assumption application fees actually received from Mortgagors on
(A) Specially Serviced Loans and (B) Performing Serviced Loans if the related assumption was processed by the Special Servicer;
(vii) 100% of Consent Fees with respect to a Specially Serviced Loan; (viii) 50% of any Consent Fees with respect to
a Performing Serviced Loan consented to by the Special Servicer (regardless of whether the Master Servicer or the Special Servicer
processes the related servicing matter); (ix) 100% of Excess Penalty Charges accrued with respect to any Serviced Loan during
the period such Serviced Loan is a Specially Serviced Loan and actually received from the Mortgagors (provided that for
the avoidance of doubt, the Special Servicer shall be entitled to any collections of Excess Penalty Charges that represent amounts
accrued while the related Serviced Loan is a Specially Serviced Loan even if collected when the Serviced Loan is not a Specially
Serviced Loan); (x) any interest or other income earned on deposits in the REO Accounts and any Loss of Value Reserve Fund;
(xi) 100% of fees for insufficient or returned checks actually received from Mortgagors relating to the accounts held by the Special
Servicer; and (xii) 100% of beneficiary statement charges actually received from Mortgagors to the extent the related beneficiary
statements were prepared by the Special Servicer. In addition, the Special Servicer shall be entitled to charge and retain reasonable
review fees in connection with any Mortgagor request with respect to any Specially Serviced Loan or with respect to any Performing
Serviced Loan as to which the Mortgagor request relates to a Major Decision or a Special Servicer Decision that is being processed
by the Special Servicer, to the extent such fees are (i) not inconsistent with the related Loan Documents, (ii) in accordance
with the Servicing Standard and (iii) actually paid by or on behalf of the related Mortgagor. The Special Servicer shall not be
entitled to any Special Servicing Fees with respect to the Outside Serviced Mortgage Loans.


 


For
the avoidance of doubt, with respect to any Excess Modification Fee, Assumption Fee, Consent Fee or other fee with respect to
a Performing Serviced Loan that is required to be split between the Master Servicer and the Special Servicer pursuant to the terms
of this Agreement, the Master Servicer and the Special Servicer shall each have the right in its sole discretion, but not any
obligation, to reduce or elect not to charge its respective percentage interest in any such fee; provided, however (x) neither
the Master 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 Master 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 Master 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 Master Servicer had charged a fee and the Master Servicer shall not be entitled to
any of such fee charged by the Special Servicer. The foregoing provisions of this paragraph shall only apply to Performing Serviced
Loans and, subject to the other terms of this Agreement, shall not prohibit any waiver or reduction by the Special Servicer of
any fee payable by the Mortgagor with respect to any Specially Serviced Loan.


 


Except
as otherwise provided herein, the Special Servicer shall pay all expenses incurred by it in connection with its servicing activities
hereunder.


 






    	-237- 



     


    

 


The
Special Servicer shall also be entitled to additional servicing compensation in the form of a Workout Fee with respect to
each Corrected Loan at the Workout Fee Rate on such Mortgage Loan or Serviced Loan Combination for so long as it remains a
Corrected Loan. The Special Servicer shall not be entitled to any Workout Fee with respect to any Outside Serviced Mortgage
Loan. The Workout Fee with respect to any Corrected Loan will cease to be payable if such loan again becomes a Specially
Serviced Loan; provided that a new Workout Fee will become payable if and when such Specially Serviced Loan again
becomes a Corrected Loan. If the Special Servicer is terminated (other than for cause) or resigns: (1) it shall retain
the right to receive any and all Workout Fees payable in respect of Mortgage Loans or Serviced Loan Combinations that became
Corrected Loans prior to the time of that termination or resignation, except the Workout Fees will no longer be payable if
any such Mortgage Loan or Serviced Loan Combination subsequently becomes a Specially Serviced Loan; and (2) it will
receive any Workout Fees payable in respect of any Mortgage Loan or Serviced Loan Combination that was, at the time of that
termination or resignation, a Specially Serviced Loan for which the resigning or terminated Special Servicer had cured the
event of default through a modification, restructuring or workout negotiated by the Special Servicer and evidenced by a
signed writing, but which had not as of the time the Special Servicer resigned or was terminated become a Corrected Loan
solely because the Mortgagor had not had sufficient time to make three consecutive full and timely Monthly Payments as
described in clause (w) of the definition of “Specially Serviced Loan” and which thereafter becomes a Corrected
Loan as a result of the Mortgagor making such three consecutive full and timely Monthly Payments as described in clause (w)
of the definition of “Specially Serviced Loan”, except the Workout Fees will no longer be payable if any such
Mortgage Loan or Serviced Loan Combination subsequently becomes a Specially Serviced Loan. In either case, the
successor special servicer will not be entitled to any portion of such Workout Fees. The Special Servicer shall also be
entitled to additional servicing compensation in the form of a Liquidation Fee (other than with respect to the Outside
Serviced Mortgage Loans) payable out of the Liquidation Proceeds prior to the deposit of the Net Liquidation Proceeds in the
Collection Account or the Loan Combination Custodial Account, as applicable. However, no Liquidation Fee will be payable with
respect to an Outside Serviced Mortgage Loan or in connection with, or out of, Liquidation Proceeds as set forth in the final
two provisos of the definition of “Liquidation Fee” herein. Notwithstanding anything herein to the contrary, the
Special Servicer shall not be entitled to receive both a Liquidation Fee and a Workout Fee with respect to any specific
collections or proceeds on any Mortgage Loan or Serviced Loan Combination. For purposes of the foregoing provisions of this Section 3.12(c),
a termination and removal of the Special Servicer under Section 6.08 of this Agreement shall be deemed to
constitute a termination without cause.


 


If
at any time a Mortgage Loan or Serviced Loan Combination becomes a Specially Serviced Loan, the Special Servicer shall use its
reasonable efforts to collect the amount of any Special Servicing Fee, Liquidation Fee and/or Workout Fee from the related Mortgagor
pursuant to the related Loan Documents, including exercising all remedies available under such Loan Documents that would be in
accordance with the Servicing Standard, specifically taking into account the costs or likelihood of success of any such collection
efforts and the Realized Loss and that would be incurred by Certificateholders in connection therewith as opposed to the Realized
Loss that would be incurred as a result of not collecting such amounts from the related Mortgagor.


 


The
Special Servicer shall not be entitled to any Liquidation Fee with respect to any Outside Serviced Mortgage Loan or any Outside
Serviced Companion Loan. In addition, the


 






    	-238- 



     


    

 


Special Servicer will not be entitled to retain any portion of Excess Interest paid
on any Mortgage Loan.


 


Notwithstanding
anything herein to the contrary, in the case of a Serviced Loan Combination, in no event shall Special Servicing Compensation
with respect to the related Mortgage Loan (including an REO Mortgage Loan) be payable out of payments and other collections with
respect to the related Serviced Pari Passu Companion Loan(s), and in no event shall Special Servicing Compensation with respect
to the related Serviced Pari Passu Companion Loan(s) (including an REO Companion Loan) be payable out of payments and other collections
with respect to the related Mortgage Loan or the Mortgage Pool. In addition, with respect to any Serviced Subordinate Companion
Loan, unless otherwise provided in the related Co-Lender Agreement, in no event shall Special Servicing Compensation with respect
to such Companion Loan (including an REO Companion Loan) be payable out of payments and other collections with respect to any
related Serviced Pari Passu Companion Loan(s), the related Mortgage Loan or the Mortgage Pool. This paragraph is in no way intended
to limit the rights of the Special Servicer under the related Co-Lender Agreement to seek payment of unpaid Special Servicing
Compensation with respect to any Serviced Companion Loan from the related Serviced Companion Loan Holder.


 


(d)         The
Master Servicer, Special Servicer, the Certificate Administrator and Trustee shall be entitled to reimbursement from the
Trust Fund for the costs and expenses incurred by them in the performance of their duties under this Agreement which are
“unanticipated expenses incurred by the REMIC” within the meaning of Treasury Regulations
Section 1.860G-1(b)(3)(iii). Such expenses shall include, by way of example and not by way of limitation, environmental
assessments, Appraisals in connection with foreclosure, the fees and expenses of any administrative or judicial proceeding
and expenses expressly identified as reimbursable in Section 3.06(a)(vi) of this Agreement.


 


(e)         No
provision of this Agreement or of the Certificates shall require the Master Servicer, the Special Servicer, the Certificate Administrator
or the Trustee to expend or risk their own funds or otherwise incur any financial liability in the performance of any of their
duties hereunder or thereunder, or in the exercise of any of their rights or powers, if, in the good faith business judgment of
the Master Servicer, Special Servicer, the Certificate Administrator or the Trustee, as the case may be, repayment of such funds
would not be ultimately recoverable from late payments, Net Insurance Proceeds, Net Condemnation Proceeds, Net Liquidation Proceeds
and other collections on or in respect of the Mortgage Loans or Serviced Loan Combination (to the extent recovery is permitted
from a Serviced Loan Combination hereunder) or from adequate indemnity from other assets comprising the Trust Fund against such
risk or liability.


 


If
the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator or the Trustee receives a request
or inquiry from a Mortgagor, any Certificateholder or any other Person the response to which would, in the Master Servicer’s,
the Special Servicer’s or the Operating Advisor’s commercially reasonable judgment or the Certificate Administrator’s
or the Trustee’s good faith business judgment require the assistance of Independent legal counsel or other consultant to
the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator or the Trustee the cost of which
would not be an expense of the Trust Fund hereunder, then the Master Servicer, the Special Servicer, the Operating Advisor, the


 






    	-239- 



     


    

 


Certificate Administrator or the Trustee, as the case may be, shall not be required to take any action in response to such request
or inquiry unless the Mortgagor or such Certificateholder or such other Person, as applicable, makes arrangements for the payment
of the Master Servicer’s, the Special Servicer’s, the Operating Advisor’s, the Certificate Administrator’s
or the Trustee’s expenses associated with such counsel (including, without limitation, posting an advance payment for such
expenses) satisfactory to the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator or the
Trustee as the case may be, in its sole discretion. Unless such arrangements have been made, the Master Servicer, the Special
Servicer, the Operating Advisor, the Certificate Administrator or the Trustee as the case may be, shall have no liability to any
Person for the failure to respond to such request or inquiry.


 


(f)          With
respect to each Collection Period, the Special Servicer shall deliver or cause to be delivered to the Master Servicer, within
two Business Days following the related Determination Date, and the Master Servicer shall deliver, to the extent it has received
such information, to the Certificate Administrator, without charge and within one Business Day prior to the related Distribution
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 during the related Collection Period; provided, that no such report shall
be due in any month during which no Disclosable Special Servicer Fees were received.


 


(g)          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 or rebates) from any Person (including, without limitation,
the Trust, any Mortgagor, any Manager, any guarantor or indemnitor in respect of a Serviced Mortgage Loan or Serviced Companion
Loan and any purchaser of any Serviced Mortgage Loan, Serviced Companion Loan or REO Property) in connection with the disposition,
workout or foreclosure of any Serviced Loan, the management or disposition of any REO Property, or the performance of any other
special servicing duties under this Agreement, other than as expressly provided in this Section 3.12; provided
that such prohibition shall not apply to Permitted Special Servicer/Affiliate Fees or the fees received by any Person acting
as an Outside Servicer or Outside Special Servicer as expressly provided for under the applicable Outside Servicing Agreement
with respect to an Outside Serviced Mortgage Loan, or as master servicer or special servicer as expressly provided for under the
applicable Other Pooling and Servicing Agreement governing the securitization of a Serviced Companion Loan. For the avoidance
of doubt, the foregoing is not intended to act as a prohibition on the right of any entity acting in the capacities of both Master
Servicer and Special Servicer from receiving or retaining any fees, compensation or other remuneration it is entitled to in its
capacity as Master Servicer pursuant to this Agreement.


 


(h)          If
a Servicing Shift Mortgage Loan becomes a Specially Serviced Mortgage Loan prior to the related Servicing Shift Date, the Special
Servicer shall service and administer the related Loan Combination and any related REO Property in the same manner as any other
Specially Serviced Loan or REO Property and shall be entitled to all rights and compensation earned with respect to the related
Loan Combination during the period for which it acts as Special Servicer of the related Loan Combination. With respect to a Servicing
Shift Mortgage Loan, prior to the related Servicing Shift Date, no other special servicer will be entitled to any such compensation
or have such rights and obligations. If a Servicing Shift Mortgage Loan is still a Specially Serviced Mortgage Loan on the related
Servicing Shift Date, the related Outside Special Servicer and the


 






    	-240- 



     


    

 


Special Servicer shall be entitled to compensation with respect
to the related Loan Combination as if the Special Servicer were being terminated as Special Servicer and the related Outside Special
Servicer were replacing it as the successor special servicer. Upon receipt of notice of its termination as Special Servicer with
respect to a Servicing Shift Mortgage Loan, the Special Servicer shall reasonably cooperate with the related Outside Special Servicer
in connection with the servicing transition of such Servicing Shift Mortgage Loan on and after the related Servicing Shift Date.


 


Section 3.13           Compensating
Interest Payments. The Master Servicer shall deliver to the Certificate Administrator for deposit in the
Lower-Tier REMIC Distribution Account (other than the portion of any Compensating Interest Payment described below that is
allocable to a Serviced Companion Loan) on each Master Servicer Remittance Date, without any right of reimbursement therefor,
an amount, with respect to each Mortgage Loan (other than an Outside Serviced Mortgage Loan) and any related Serviced Pari
Passu Companion Loan, equal to the lesser of:


 


(i) 
    the aggregate of all Prepayment Interest Shortfalls incurred in connection with voluntary Principal
Prepayments received in respect of the Mortgage Loans (other than the Outside Serviced Mortgage Loans) and any related
Serviced Pari Passu Companion Loan(s) (in each case other than a Specially Serviced Loan or a Mortgage Loan or any related
Serviced Pari Passu Companion Loan on which the Special Servicer allowed a prepayment on a date other than the applicable Due
Date) for the related Distribution Date; and


 


(ii)     the
aggregate of (A) that portion of the Master Servicer’s Servicing Fees for the related Distribution Date that is, in
the case of each Mortgage Loan, Serviced Pari Passu Companion Loan and REO Loan for which such Servicing Fees are being paid in
such Collection Period, calculated at a rate of 0.00250% per annum, and (B) all Prepayment Interest Excesses received
by the Master Servicer during such Collection Period with respect to the Mortgage Loans (and, so long as a Loan Combination is
serviced under this Agreement, any related Serviced Pari Passu Companion Loan) subject to prepayment and net investment earnings
on such Prepayment Interest Excesses. In no event will the rights of the Certificateholders to the offset of the aggregate Prepayment
Interest Shortfalls be cumulative.


 


If
a Prepayment Interest Shortfall occurs with respect to a Mortgage Loan as a result of the Master Servicer allowing the related
Mortgagor to deviate (a “Prohibited Prepayment”) from the terms of the related Loan Documents regarding Principal
Prepayments (other than (w) if the Mortgage Loan is an Outside Serviced Mortgage Loan, (x) subsequent to a default under
the related Loan Documents or if the Mortgage Loan is a Specially Serviced Loan, (y) pursuant to applicable law or a court
order or otherwise in such circumstances where the Master Servicer is required to accept such principal prepayment in accordance
with the Servicing Standard, or (z) in connection with the payment of any Insurance Proceeds or Condemnation Proceeds), then
for purposes of calculating the Compensating Interest Payment for the related Distribution Date, the Master Servicer shall pay,
without regard to clause (ii) of the preceding paragraph, the amount of the Prepayment Interest Shortfall with respect to
such Mortgage Loan otherwise described in clause (i) of the preceding paragraph in connection with such Prohibited Prepayment.


 






    	-241- 



     


    

 


Compensating
Interest Payments with respect to a Serviced Loan Combination shall be allocated between the related Mortgage Loan and the related
Serviced Pari Passu Companion Loan(s) in accordance with their respective principal amounts, and the Master Servicer shall pay
the portion of such Compensating Interest Payments allocable to a related Serviced Pari Passu Companion Loan to the holder thereof.


 


Section 3.14           Application
of Penalty Charges and Modification Fees.


 


(a)          On
or prior to the second Business Day before each Master Servicer Remittance Date, the Master Servicer shall apply all Penalty Charges
and Modification Fees (to the extent permitted under any related Co-Lender Agreement (in the case of a Serviced Loan Combination)
and not applied pursuant to Section 3.06A(a)(ii) or Section 3.06(a)(ii), as applicable, of this Agreement)
received by it with respect to any Mortgage Loan or Serviced Loan Combination, including an Outside Serviced Mortgage Loan (to
the extent allocable to such Outside Serviced Mortgage Loan pursuant to the related Co-Lender Agreement and remitted to the Master
Servicer by the related Outside Servicer) during the related Collection Period, as follows:


 


(i)          first,
to the extent of all Penalty Charges and Modification Fees (in such order), to pay or reimburse the Master Servicer, the Special
Servicer and/or the Trustee, as applicable, for all outstanding Advances (including unreimbursed Advances that have been determined
to be Nonrecoverable Advances) and the related Advance Interest Amounts and other outstanding Additional Trust Fund Expenses (exclusive
of Special Servicing Fees, Workout Fees and Liquidation Fees) other than Borrower Delayed Reimbursements, in each case, with respect
to such Mortgage Loan or Serviced Loan Combination;


 


(ii)         second,
to the extent of all remaining Penalty Charges and Modification Fees (in such order), as a reimbursement to the Trust of all Advances
(and related Advance Interest Amounts) with respect to such Mortgage Loan or Serviced Loan Combination previously determined to
be Nonrecoverable Advances and previously reimbursed to the Master Servicer, the Special Servicer and/or the Trustee, as applicable,
from amounts on deposit in the Collection Account (and such amounts will be retained or deposited in the Collection Account as
recoveries of such Nonrecoverable Advances and related Advance Interest Amounts) other than Borrower Delayed Reimbursements;


 


(iii)        third,
to the extent of all remaining Penalty Charges and Modification Fees (in such order), as a reimbursement to the Trust of all other
Additional Trust Fund Expenses (exclusive of Special Servicing Fees, Workout Fees and Liquidation Fees) with respect to such Mortgage
Loan or Serviced Loan Combination previously paid from the Collection Account or related Loan Combination Custodial Account (and
such amounts will be retained or deposited in the Collection Account or related Loan Combination Custodial Account as recoveries
of such Additional Trust Fund Expenses) other than Borrower Delayed Reimbursements; and


 


(iv)        fourth,
to the extent of any remaining Penalty Charges and any remaining Modification Fees, to the Master Servicer or the Special Servicer,
as applicable, as servicing compensation, pro rata, based on their entitlement set forth in Section 3.12 of
this Agreement prior to the applications set forth in clauses (i) through (iii) above;


 






    	-242- 



     


    

 


provided
that, notwithstanding the foregoing, in the case of a Loan Combination, Penalty Charges shall be allocated for the
purposes and in the order set forth in the related Co-Lender Agreement.


 


(b)         In
connection with the operation of the provisions of this Section 3.14, not later than the 25th day of the month in
which each Distribution Date occurs (beginning with the 25th day of the month following the first Collection Period in which an
Additional Trust Fund Expense, Advance or Advance Interest Amount is incurred), the Master Servicer shall deliver to the Special
Servicer a report in the form reasonably agreed to by both the Master Servicer and the Special Servicer setting forth information
regarding (1) the amount of Penalty Charges, Modification Fees and Assumption Fees collected by the Master Servicer and the
Special Servicer, as applicable, and (2) the related loan expenses and other amounts paid to the Trust from such Penalty
Charges, Modification Fees and Assumption Fees, in each case for the related Collection Period or other reporting period as agreed
to by the Master Servicer and the Special Servicer. The Master Servicer shall respond promptly to any inquiries of the Special
Servicer with respect to the contents of any such report and shall provide any supporting information with respect thereto that
is reasonably requested by the Special Servicer.


 


Section 3.15           Access
to Certain Documentation. The Master Servicer and Special Servicer shall provide to the Trustee, the Certificate
Administrator, the Controlling Class Representative (but only prior to the occurrence and continuance of any Consultation
Termination Event), the Operating Advisor, the Underwriters, the Initial Purchasers, the Depositor and any Certificateholders
and Serviced Companion Loan Holders that are, in the case of any Certificateholder or Serviced Companion Loan Holder,
federally insured financial institutions, the Federal Reserve Board, the FDIC and the OCC and the supervisory agents and
examiners of such boards and such corporations, and any other governmental or regulatory body to the jurisdiction of which
any Certificateholder or Serviced Companion Loan Holder is subject, access to the documentation regarding the Mortgage Loans
required by applicable regulations of the Federal Reserve Board, FDIC, OCC or any such governmental or regulatory body, such
access being afforded without charge but only upon reasonable request and during normal business hours at the offices of the
Master Servicer or Special Servicer (which access shall be limited, in the case of the Serviced Companion Loan Holders or any
regulatory authority seeking such access in respect of the Serviced Companion Loan Holders, to records relating to the
Serviced Companion Loans). Nothing in this Section 3.15 shall detract from the obligation of the Master Servicer
and Special Servicer to observe any applicable law prohibiting disclosure of information with respect to the Mortgagors, and
the failure of the Master Servicer and Special Servicer to provide access as provided in this Section 3.15 as a
result of such obligation shall not constitute a breach of this Section 3.15.


 


In
connection with providing or granting any information or access pursuant to the prior paragraph to a Certificateholder, a Serviced
Companion Loan Holder or any regulatory authority that may exercise authority over a Certificateholder or Serviced Companion Loan
Holder, the Master Servicer and the Special Servicer may each require payment from such Certificateholder or Serviced Companion
Loan Holder of a sum sufficient to cover the reasonable costs and expenses of providing such information or access, including
copy charges and reasonable fees for employee time and for space; provided that no charge may be made if such information
or access was required to be given or made available without charge under applicable law. In connection with providing Certificateholders
or beneficial owners of Certificates access to the


 






    	-243- 



     


    

 


information described in the preceding paragraph, the Master Servicer and the
Special Servicer shall require (prior to affording such access) a written confirmation executed by the requesting Person
substantially in such form as may be reasonably acceptable to the Master Servicer or the Special Servicer, as the case may be,
generally to the effect that such Person is a Holder of Certificates or a beneficial holder of book entry Certificates and will
keep such information confidential.


 


In
addition, in connection with providing access to information pursuant to this Section 3.15, each of the Master Servicer
and the Special Servicer may (i) affix a reasonable disclaimer to any information provided by it for which it is not the
original source (without suggesting liability on the part of any other party hereto); (ii) affix to any information provided
by it a reasonable statement regarding securities law restrictions on such information and/or condition access to information
on the execution of a reasonable confidentiality agreement; (iii) withhold access to confidential information or any intellectual
property; and (iv) withhold access to items of information contained in the Servicing File for any Mortgage Loan or Serviced
Companion Loan if the disclosure of such items would constitute a waiver of the attorney-client privilege.


 


Each
of the Master Servicer and the Special Servicer, as applicable, shall, without charge, make a knowledgeable Servicing Officer
available via telephone to verbally answer questions from the Directing Holder (unless, if the Controlling Class Representative
is the related Directing Holder, a Control Termination Event has occurred and is continuing) and the Operating Advisor, on a monthly
basis, during regular business hours at such time and for such duration as the Master Servicer or the Special Servicer, as applicable,
on the one hand, and the Directing Holder (unless, if the Controlling Class Representative is the related Directing Holder, a
Control Termination Event has occurred and is continuing) or the Operating Advisor, as applicable, on the other hand, shall reasonably
agree, regarding the performance and servicing of the applicable Serviced Mortgage Loans and/or related REO Properties for which
the Master Servicer or the Special Servicer, as applicable, is responsible. In any event, the Directing Holder or the Operating
Advisor, as applicable, agree to identify for the Master Servicer and the Special Servicer in advance (but at least two (2)
Business Days prior to the related monthly conference) the applicable Mortgage Loans (or Serviced Loan Combination) and/or REO
Properties it intends to discuss. As a condition to such disclosure, the related Directing Holder shall execute a confidentiality
agreement substantially in the form of Exhibit M-4 to this Agreement and an Investor Certification.


 


The
Master Servicer may (but shall not be required to), in accordance with such rules and procedures as it may adopt in its sole discretion,
make available through the Master Servicer’s website or otherwise, any additional information relating to the Mortgage Loans,
the Serviced Companion Loans, the related Mortgaged Properties and/or the related Mortgagors that is not Privileged Information,
for review by the Depositor, the Trustee, the Master Servicer, the Special Servicer and the Operating Advisor.


 


The
Special Servicer shall deliver to the Operating Advisor such reports and other information produced or otherwise available to
any Outside Controlling Note Holder, the Controlling Class Representative or Certificateholders generally, as requested by the
Operating Advisor in support of the performance of the Operating Advisor’s obligations under this Agreement in electronic
format.


 






    	-244- 



     


    

 


The
Operating Advisor hereby agrees that it shall use the information provided to it by the Special Servicer solely for purposes of
performing its duties as Operating Advisor under this Agreement and shall not disclose such information to any other Person or
entity except (i) with respect to Privileged Information, pursuant to Section 3.29(j) of this Agreement, or (ii) with respect
to any information other than Privileged Information, to the extent necessary to support its conclusions in its Operating Advisor
Annual Report required under Section 3.29 of this Agreement or to discharge its other duties under this Agreement.


 


Section 3.16           Title
and Management of REO Properties.


 


(a)          In
the event that title to any Mortgaged Property (other than a Mortgaged Property with respect to an Outside Serviced Mortgage Loan)
is acquired for the benefit of Certificateholders (or, with respect to a Serviced Loan Combination, for the benefit of the Certificateholders
and the related Serviced Companion Loan Holder(s)) (as a collective whole as if such Certificateholders and, if applicable, such
Serviced Companion Loan Holder(s) constituted a single lender) (either by the Trust Fund or by a single member limited liability
company established for that purpose) in foreclosure, by deed-in-lieu of foreclosure or upon abandonment or reclamation from
bankruptcy, the deed or certificate of sale shall be taken in the name of a nominee of the Trustee (which shall not include the
Master Servicer), or a separate trustee or co-trustee, on behalf of the Trust Fund and any related Serviced Companion Loan Holders.
The Special Servicer, on behalf of the Trust Fund, shall sell any REO Property prior to the close of the third calendar year following
the year in which the Lower-Tier REMIC acquires ownership of such REO Property, within the meaning of Treasury Regulations
Section 1.856-6(b)(1), for purposes of Code Section 860G(a)(8), unless (i) the IRS grants (or does not deny) an
extension of time (an “REO Extension”) to sell such REO Property or (ii) the Special Servicer obtains
an Opinion of Counsel for the Special Servicer, the Certificate Administrator and the Trustee, addressed to the Special Servicer,
the Certificate Administrator and the Trustee, to the effect that the holding by the Lower-Tier REMIC of such REO Property subsequent
to the close of the third calendar year following the year in which such acquisition occurred will not result in the imposition
of taxes on “prohibited transactions” (as defined in Code Section 860F) of either Trust REMIC, or cause either
Trust REMIC to fail to qualify as a REMIC under the Code at any time that any of the Lower-Tier Regular Interests or any of the
Regular Certificates is outstanding. If the Special Servicer is granted (or is not denied) the REO Extension contemplated by clause (i)
of the immediately preceding sentence or obtains the Opinion of Counsel contemplated by clause (ii) of the immediately preceding
sentence, the Special Servicer shall sell such REO Property within such longer period as is permitted by such REO Extension or
such Opinion of Counsel, as the case may be. Any expense incurred by the Special Servicer in connection with its receiving the
REO Extension contemplated by clause (i) of the second preceding sentence or its obtaining the Opinion of Counsel contemplated
by clause (ii) of the second preceding sentence shall be an expense of the Trust Fund payable out of the Collection Account
pursuant to Section 3.06(a) of this Agreement. The Special Servicer, on behalf of the Trust Fund and any related Serviced
Companion Loan Holder, in accordance with the Servicing Standard, shall dispose of any REO Property held by the Trust Fund (i) prior
to the last day of such period (taking into account extensions) by which such REO Property is required to be disposed of
pursuant to the provisions of the immediately preceding sentence in a manner provided under Section 3.17 of this Agreement
and (ii) on the same terms and conditions as if it were the owner of such REO Property. The Special Servicer shall manage,
conserve, protect and operate each REO Property for the Certificateholders and, if applicable, the


 






    	-245- 



     


    

 


related Serviced Companion
Loan Holder, solely for the purpose of its prompt disposition and sale in a manner which does not cause such REO Property to fail
to qualify as “foreclosure property” within the meaning of Code Section 860G(a)(8) or result in the receipt
by the Trust Fund of any “income from non-permitted assets” within the meaning of Code Section 860F(a)(2)(B) or
(i) endanger the status of either Trust REMIC as a REMIC or (ii) result in the imposition of a tax upon either Trust
REMIC or the Trust Fund.


 


(b)         The
Special Servicer shall have full power and authority, subject only to the specific requirements and prohibitions of this
Agreement, to do any and all things in connection with any REO Property (other than an REO Property related to an Outside
Serviced Mortgage Loan) as are consistent with the Servicing Standard and the terms of this Agreement, all on such terms and
for such period as the Special Servicer deems to be in the best interests of Certificateholders and, if applicable, the
related Serviced Companion Loan Holder(s) (as a collective whole as if such Certificateholders and, if applicable, the
related Serviced Companion Loan Holder(s) constituted a single lender (and, in the case of a Serviced AB Loan Combination,
taking into account the subordinate nature of any related Subordinate Companion Loan)), and, in connection therewith, the
Special Servicer shall only agree to the payment of management fees that are consistent with general market standards or to
terms that are more favorable. Consistent with the foregoing, the Special Servicer shall cause or permit to be earned with
respect to such REO Property any “net income from foreclosure property,” within the meaning of Code
Section 860G(c), which is subject to tax under the REMIC Provisions only if it has determined, and has so advised the
Certificate Administrator in writing, that the earning of such income on a net after-tax basis could reasonably be expected
to result in a greater recovery on behalf of Certificateholders and, if applicable, the related Companion Loan Holder(s) (as
a collective whole as if such Certificateholders and, if applicable, the related Companion Loan Holder(s), constituted a
single lender (and, in the case of a Serviced AB Loan Combination, taking into account the subordinate nature of any related
Subordinate Companion Loan)) than an alternative method of operation or rental of such REO Property that would not be
subject to such a tax. The Special Servicer shall segregate and hold all revenues received by it with respect to any
REO Property separate and apart from its own funds and general assets and shall establish and maintain with respect to any
REO Property a segregated custodial account (each, an “REO Account”), each of which shall be an Eligible
Account and (subject to any changes in the identities of the Special Servicer and/or the Trustee) shall be entitled
“Midland Loan Services, a Division of PNC Bank, National Association, as Special Servicer, on behalf of Wilmington
Trust, National Association, as Trustee, for the benefit of the registered Holders of Citigroup Commercial Mortgage Trust
2017-C4, Commercial Mortgage Pass-Through Certificates, Series 2017-C4, [IN THE CASE OF AN REO PROPERTY RELATED TO A SERVICED
LOAN COMBINATION: and the related Serviced Companion Loan Holder, as their interests may appear], REO Account.” The
Special Servicer shall be entitled to withdraw for its account any interest or investment income earned on funds deposited in
an REO Account to the extent provided in Section 3.07(b) of this Agreement. The Special Servicer shall deposit or
cause to be deposited in the REO Account, within two (2) Business Days after receipt of properly identified funds, all
revenues and proceeds received by it with respect to any REO Property, and shall withdraw therefrom funds necessary for the
proper operation, management and maintenance of such REO Property and for other Property Protection Expenses with respect to
such REO Property, including:


 


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


 






    	-246- 



     


    

 


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


 


(iii)        all
costs and expenses reasonable and necessary to protect, maintain, manage, operate, repair and restore any REO Property including,
if applicable, the payments of any ground rents in respect of such REO Property; and


 


(iv)        any
taxes imposed on either Trust REMIC in respect of net income from foreclosure property in accordance with Section 4.05
of this Agreement.


 


To
the extent that such REO Proceeds are insufficient for the purposes set forth in clauses (i) through (iv) above and the Special
Servicer has provided written notice of such shortfall to the Master Servicer at least five (5) Business Days (or, in an emergency
situation or on an urgent basis, two (2) Business Days, provided that the written notice sets forth the nature of the emergency
or the basis of the urgency) prior to the date that such amounts are due, the Master Servicer shall advance the amount of such
shortfall unless the Master Servicer determines, in accordance with the Servicing Standard, that such Advance would be a Nonrecoverable
Advance (in which case such costs shall be an expense of the Trust Fund and paid by the Master Servicer out of the Collection
Account). If the Master Servicer does not make any such Advance in violation of the immediately preceding sentence, the Trustee
shall make such Advance unless the Trustee determines that such Advance would be a Nonrecoverable Advance. The Trustee shall be
entitled to rely, conclusively, on any determination by the Master Servicer that an Advance, if made, would be a Nonrecoverable
Advance. The Trustee, in determining whether or not a proposed Advance would be a Nonrecoverable Advance, shall use its good faith
business judgment. The Master Servicer or the Trustee, as applicable, shall be entitled to reimbursement of such Advances (with
interest at the Advance Rate) made pursuant to the preceding sentence, to the extent set forth in Section 3.06
and/or, if applicable, Section 3.06A of this Agreement. The Special Servicer shall withdraw from each REO Account
and remit to the Master Servicer for deposit into the Collection Account, or, for a Serviced Loan Combination, the related Loan
Combination Custodial Account, on a monthly basis prior to the related Master Servicer Remittance Date (but not earlier than two
(2) Business Days after such amounts are received and properly identified) the Net REO Proceeds, Net Liquidation Proceeds, Net
Condemnation Proceeds and Net Insurance Proceeds received or collected from each REO Property during the related Collection Period,
except that in determining the amount of any such Net REO Proceeds, the Special Servicer may retain in each REO Account reasonable
reserves for repairs, replacements and necessary capital improvements and other related expenses. Notwithstanding the foregoing,
the Special Servicer shall not:


 


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


 


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


 


(iii)        authorize
or permit any construction on any REO Property, other than the repair or maintenance thereof or 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


 






    	-247- 



     


    

 


improvement was
completed before default on the related Mortgage Loan or Serviced Loan Combination became imminent, all within the meaning of
Code Section 856(e)(4)(B); or


 


(iv)        Directly
Operate or allow any Person to Directly Operate any REO Property on any date more than 90 days after its date of acquisition
by the Trust Fund, unless such Person is an Independent Contractor;


 


unless,
in any such case, the Special Servicer has requested and received an Opinion of Counsel addressed to the Special Servicer, any
related Serviced Companion Loan Holder, the Certificate Administrator and the Trustee (which opinion shall be an expense of the
Trust Fund and, if any related Serviced Companion Loan is part of a REMIC, the related Serviced Companion Loan Holder) to the
effect that such action will not cause such REO Property to fail to qualify as “foreclosure property” within the meaning
of Code Section 860G(a)(8) (determined without regard to the exception applicable for purposes of Code Section 860D(a)) at
any time that it is held by the Trust Fund, in which case the Special Servicer may take such actions as are specified in such
Opinion of Counsel.


 


The
Special Servicer shall be required to contract with an Independent Contractor, the fees and expenses of which shall be an expense
of the Trust Fund and payable out of REO Proceeds, for the operation and management of any REO Property, within 90 days of
the Trust Fund’s acquisition thereof (unless the Special Servicer shall have provided the Trustee and the Certificate Administrator
with an Opinion of Counsel that the operation and management of any REO Property other than through an Independent Contractor
shall not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Code Section 860G(a)(8)) (which
opinion shall be an expense of the Trust Fund), provided that:


 


(i)          the
terms and conditions of any such contract shall be reasonable and customary for the area and type of property and shall not be
inconsistent herewith;


 


(ii)         any
such contract shall require, or shall be administered to require, that the Independent Contractor pay all costs and expenses incurred
in connection with the operation and management of such REO Property, including those listed above, and remit all related revenues
(net of such costs and expenses) to the Special Servicer as soon as practicable, but in no event later than thirty days following
the receipt thereof by such Independent Contractor;


 


(iii)        none
of the provisions of this Section 3.16(b) relating to any such contract or to actions taken through any such Independent
Contractor shall be deemed to relieve the Special Servicer of any of its duties and obligations to the Trust Fund or the Trustee
on behalf of the Certificateholders and, if applicable, any related Serviced Companion Loan Holder with respect to the operation
and management of any such REO Property; and


 


(iv)       
the Special Servicer shall be obligated with respect thereto to the same extent as if it alone were performing all duties
and obligations in connection with the operation and management of such REO Property.


 


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


 






    	-248- 



     


    

 


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


 


(c)          When
and as necessary, the Special Servicer shall send to the Trustee and the Certificate Administrator and the related Serviced Companion
Loan Holder (or the master servicer or special servicer for the related Other Securitization Trust on its behalf) a statement
prepared by the Special Servicer setting forth the amount of net income or net loss, as determined for federal income tax purposes,
resulting from the operation and management of a trade or business on, the furnishing or rendering of a non-customary service
to the tenants of, or the receipt of any other amount not constituting Rents from Real Property in respect of, any REO Property
in accordance with Section 3.16(a) and Section 3.16(b) of this Agreement.


 


(d)         Notwithstanding
anything to the contrary, this Section 3.16 shall not apply to any REO Property related to an Outside Serviced Mortgage
Loan.


 


Section 3.17           Sale
of Defaulted Loans and REO Properties; Sale of Outside Serviced Mortgage Loans.


 


(a)         The
parties hereto may sell or purchase, or permit the sale or purchase of, a Mortgage Loan (excluding an Outside Serviced Mortgage
Loan) only (i) on the terms and subject to the conditions set forth in this Section 3.17, (ii) as otherwise
expressly provided in or contemplated by Sections 2.03 and 9.01 of this Agreement, or (iii) (A) in
the case of a Mortgage Loan related to a Serviced Loan Combination in accordance with and subject to the provisions of the related
Co-Lender Agreement and Section 3.28 of this Agreement and (B) in the case of a Mortgage Loan with a related
mezzanine loan or subordinate mortgage loan, in accordance with and subject to the provisions of the related intercreditor agreement.


 


(b)         Promptly
upon a Serviced Loan becoming a Defaulted Loan and if the Special Servicer determines in accordance with the Servicing
Standard that it would be in the best interests of the Certificateholders and, in the case of a Serviced Pari Passu Loan
Combination, any related Serviced Pari Passu Companion Loan Holder (as a collective whole as if such Certificateholders and,
in the case of a Serviced Pari Passu Loan Combination, any related Serviced Pari Passu Companion Loan Holder, constituted a
single lender) to attempt to sell such Defaulted Loan, the Special Servicer shall use reasonable efforts to solicit offers
for such Defaulted Loan on behalf of the Certificateholders and, if applicable, any related Serviced Pari Passu Companion
Loan Holder in such manner as will be reasonably likely to realize a fair price. Subject to the other subsections of this Section 3.17,
the Special Servicer shall accept the first (and, if multiple offers are contemporaneously received, the highest) cash offer
received from any Person that constitutes a fair price for such Defaulted Loan. The Special Servicer shall notify the
Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event), any related
Outside Controlling Note Holder and the Operating Advisor of any offers received regarding the sale of any Defaulted Loan.
Any Serviced Pari Passu Companion Loan that is part of a Defaulted Serviced Loan Combination is to be sold together with the
related Mortgage Loan, subject to this Section 3.17 and any additional requirements set forth in the related
Co-Lender Agreement.


 


(c)         The
Special Servicer shall give the Trustee, the Certificate Administrator, the Master Servicer, any related Serviced Companion Loan
Holder (in the case of a Serviced Loan


 






    	-249- 



     


    

 


Combination), the Controlling Class Representative (prior to the occurrence and continuance
of a Consultation Termination Event), any related Outside Controlling Note Holder (if a Serviced Outside Controlled Loan Combination
is involved) and the Operating Advisor not less than five (5) Business Days’ prior written notice of its intention to sell
any Defaulted Loan. No Interested Person shall be obligated to submit an offer to purchase any Defaulted Loan, and notwithstanding
anything to the contrary contained herein, neither the Trustee, in its individual capacity, nor any of its Affiliates may offer
to purchase, or purchase any Defaulted Loan pursuant hereto.


 


(d)         Whether
any cash offer constitutes a fair price for any Defaulted Loan for purposes of Section 3.17(b) of this Agreement shall
be determined by the Special Servicer, if the offeror is a Person other than an Interested Person, and by the Trustee, if the
offeror is an Interested Person (provided that the Trustee may not be an offeror); provided, however, that
no offer from an Interested Person shall constitute a fair price unless (i) it is the highest offer received and (ii) at
least two other offers are received from independent third parties; and provided,  further, notwithstanding the immediately
preceding proviso, the Purchase Price for any Defaulted Loan (and any equivalent amount for any related Serviced Companion Loan)
shall be deemed a fair price in all cases, including with respect to any offer from an Interested Person. In all cases under this
Agreement (except to the extent the Trustee is not required to determine whether any cash offer constitutes a fair price for any
Defaulted Loan pursuant to the immediately preceding sentence), in determining whether any offer received from an Interested Person
represents a fair price for any Defaulted Loan, the Trustee shall (at the expense of the Interested Person) designate an independent
third party expert in real estate or commercial mortgage loan matters with at least five (5) years’ experience in valuing
or investing in mortgage loans similar to such Defaulted Loan that has been selected with reasonable care by the Trustee to determine
if such cash offer constitutes a fair price for such Defaulted Loan; provided that the Trustee will not engage a third
party expert whose fees exceed a commercially reasonable amount as determined by the Trustee. The reasonable costs of all appraisals,
inspection reports and broker opinions of value incurred by any such third party pursuant to this Section 3.17(d)
will be covered by, and will be reimbursable by the Interested Person. The Trustee will be entitled to rely conclusively upon
such third party’s determination. In determining whether any such offer from a Person other than an Interested Person constitutes
a fair price for any such Defaulted Loan, the Special Servicer shall take into account (in addition to the results of any Appraisal,
updated Appraisal or narrative Appraisal that it may have obtained pursuant to this Agreement within the prior 9 months), among
other factors, the period and amount of any delinquency on such Defaulted Loan, the occupancy level and physical condition of
the related Mortgaged Property and the state of the local economy. The appraiser conducting any new Appraisal for determining
whether any offer from a Person other than an Interested Person represents a fair price for any Defaulted Loan shall be an Appraiser
selected by the Special Servicer. The cost of any such Appraisal shall be covered by, and shall be reimbursable to, the Master
Servicer as a Property Advance if no Interested Person is offering to purchase such Defaulted Loan.


 


(e)          Subject
to Section 3.17(a) through Section 3.17(d), Section 3.17(f), Section 3.17(g) and
Section 3.17(m), the Special Servicer shall act on behalf of the Trust Fund and any affected Serviced Companion Loan
Holder in negotiating and taking any other action necessary or appropriate in connection with the sale of any Defaulted Loan,
and the collection of all amounts payable in connection therewith. In connection therewith, the Special Servicer may charge prospective
offerors, and may retain, fees that approximate the Special Servicer’s actual


 






    	-250- 



     


    

 


costs in the preparation and delivery of information
pertaining to such sales or exchanging offers without obligation to deposit such amounts into the Collection Account or, if applicable,
the Loan Combination Custodial Account. Any sale of any Defaulted Loan shall be final and without recourse to the Trustee, the
Certificate Administrator or the Trust Fund (except such recourse to the Trust Fund imposed by those representations and warranties
typically given in such transactions, any appropriations applied thereto and any customary closing matters), and if such sale
is consummated in accordance with the terms of this Agreement, none of the Special Servicer, the Master Servicer, the Depositor,
the Certificate Administrator, the Operating Advisor or the Trustee shall have any liability to any Certificateholder with respect
to the purchase price therefor accepted by the Special Servicer or the Trustee.


 


(f)          Subject
to (x) the rights of a holder of a mezzanine loan, under the respective intercreditor agreement, and (y) the rights of a Subordinate
Companion Loan Holder, under the respective Co-Lender Agreement, to purchase a Mortgage Loan or Serviced Loan Combination (or
senior portion thereof), unless and until a Defaulted Loan is sold pursuant to this Section, the Special Servicer shall continue
to service and administer such Defaulted Loan in accordance with the Servicing Standard and this Agreement and shall pursue such
other resolutions or recovery strategies including workout, foreclosure or sale of such Defaulted Loan, as is consistent with
this Agreement and the Servicing Standard.


 


(g)          Any
sale of a Defaulted Loan pursuant to this Section 3.17 shall be for cash only. The purchase price for any Defaulted
Loan purchased under this Section 3.17 or any Outside Serviced Mortgage Loan sold in accordance with the related Co-Lender
Agreement or Outside Servicing Agreement, shall be deposited into the Collection Account or the related Loan Combination Custodial
Account, as applicable, and the Certificate Administrator (or a Custodian appointed by it), upon receipt of (i) an Officer’s
Certificate from the Master Servicer to the effect that such deposit has been made (ii) and a Request for Release, shall release
or cause to be released to the purchaser of the Defaulted Loan the related Mortgage File, and the Trustee, the Master Servicer
or the Special Servicer, as applicable, shall execute and deliver such instruments of transfer or assignment, in each case without
recourse, as shall be necessary to vest in such purchaser ownership of such Defaulted Loan. In connection with any such purchase,
the Special Servicer and the Master Servicer shall deliver the related Servicing File (to the extent either has possession of
such file) to such purchaser.


 


(h)          The
parties hereto may sell or purchase, or permit the sale or purchase of, an REO Property (other than an REO Property related to
an Outside Serviced Mortgage Loan) only on the terms and subject to the conditions set forth in this Section 3.17.


 


(i)          The
Special Servicer shall use reasonable efforts to solicit offers for each REO Property (other than an REO Property related to an
Outside Serviced Mortgage Loan) on behalf of the Certificateholders and the related Serviced Companion Loan Holder in such manner
as will be reasonably likely to realize a fair price within the time period specified by Section 3.16 of this Agreement.
Subject to Section 3.17(m) of this Agreement, the Special Servicer shall accept the first (and, if multiple offers
are contemporaneously received, highest) cash offer received from any Person that constitutes a fair price for such REO Property.
If the Special Servicer determines, in its good faith and reasonable judgment, that it will be unable to realize a fair price
for any REO Property (other than an REO Property related to an Outside Serviced Mortgage Loan) within the


 






    	-251- 



     


    

 


time constraints imposed
by Section 3.16 of this Agreement, then the Special Servicer shall dispose of such REO Property upon such terms and
conditions as the Special Servicer shall deem necessary and desirable to maximize the recovery thereon under the circumstances
and, in connection therewith, shall accept the highest outstanding cash offer, regardless from whom received. The Liquidation
Proceeds (net of related Liquidation Expenses) for any REO Property sold hereunder shall be deposited in the Collection Account
or, if applicable, the related Loan Combination Custodial Account.


 


(j)          The
Special Servicer shall give the Trustee, the Certificate Administrator, the Master Servicer, any related Serviced Companion Loan
Holder, the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event), any
related Outside Controlling Note Holder (if a Serviced Outside Controlled Loan Combination is involved) and the Operating Advisor
not less than three (3) Business Days’ prior written notice of its intention to sell any REO Property (other than an REO
Property related to an Outside Serviced Mortgage Loan) hereunder. No Interested Person shall be obligated to submit an offer to
purchase any REO Property, and notwithstanding anything to the contrary contained herein, neither the Trustee, in its individual
capacity, nor any of its Affiliates may offer to purchase, or purchase, any REO Property pursuant hereto.


 


(k)          Whether
any cash offer constitutes a fair price for any REO Property (other than an REO Property related to an Outside Serviced
Mortgage Loan) for purposes of Section 3.17(i) of this Agreement shall be determined by the Special
Servicer, if the offeror is a Person other than an Interested Person, and by the Trustee, if the offeror is an Interested
Person (provided that the Trustee may not be an offeror); provided, however, that no offer from an
Interested Person shall constitute a fair price unless (i) it is the highest offer received and (ii) at least two
other offers are received from independent third parties; and provided, further, notwithstanding the immediately
preceding proviso, the Purchase Price for any such REO Property shall be deemed a fair price in all cases, including with
respect to any offer from an Interested Person. In determining whether any offer received from an Interested Person
represents a fair price for any such REO Property, the Trustee shall (at the expense of the Interested Person) designate an
independent third party expert in real estate or commercial mortgage loan matters with at least five (5) years’
experience in valuing or investing in properties similar to such REO Property that has been selected with reasonable care by
the Trustee to determine if such cash offer constitutes a fair price for such REO Property; provided that the Trustee
will not engage a third party expert whose fees exceed a commercially reasonable amount as determined by the Trustee. The
reasonable costs of all appraisals, inspection reports and broker opinions of value incurred by any such third party pursuant
to this Section 3.17(k) will be covered by, and will be reimbursable by the Interested Person. The Trustee will be
entitled to rely conclusively upon such third party’s determination. In determining whether any such offer from a
Person other than an Interested Person constitutes a fair price for any such REO Property, the Special Servicer shall take
into account (in addition to the results of any Appraisal, updated Appraisal or narrative Appraisal that it may have obtained
pursuant to this Agreement within the prior 9 months), among other factors, the period and amount of any delinquency on the
related Mortgage Loan or Serviced Loan Combination, the occupancy level and physical condition of such REO Property, the
state of the local economy and the obligation to dispose of such REO Property within the time period specified in Section 3.16
of this Agreement. The appraiser conducting any new Appraisal for determining whether any offer from a Person other than an
Interested Person represents a fair price for any


 






    	-252- 



     


    

 


REO Property shall be an Appraiser selected by the Special Servicer. The cost of any such Appraisal shall
be covered by, and shall be reimbursable to, the Master Servicer as a Property Advance if no Interested Person is offering to
purchase such REO Property.


 


(l)          Subject
to Section 3.17(a) through Section 3.17(k) and Section 3.17(m) of this Agreement, the Special
Servicer shall act on behalf of the Trust Fund and any affected Serviced Companion Loan Holder in negotiating and taking any other
action necessary or appropriate in connection with the sale of any Defaulted Loan or REO Property (other than an REO Property
related to an Outside Serviced Mortgage Loan), and the collection of all amounts payable in connection therewith. In connection
therewith, the Special Servicer may charge prospective offerors, and may retain, fees that approximate the Special Servicer’s
actual costs in the preparation and delivery of information pertaining to such sales or exchanging offers without obligation to
deposit such amounts into the Collection Account or, if applicable, the related Loan Combination Custodial Account. Any sale of
any Defaulted Loan or REO Property (other than an REO Property related to an Outside Serviced Mortgage Loan) shall be final and
without recourse to the Trustee, the Certificate Administrator or the Trust Fund or any related Serviced Companion Loan Holder
(except such recourse to the Trust Fund and the related Serviced Companion Loan Holder imposed by those representations and warranties
typically given in such transactions, any appropriations applied thereto and any customary closing matters), and if such sale
is consummated in accordance with the terms of this Agreement, none of the Special Servicer, the Master Servicer, the Depositor,
the Certificate Administrator, the Operating Advisor or the Trustee shall have any liability to any Certificateholder with respect
to the purchase price therefor accepted by the Special Servicer or the Trustee.


 


(m)          Notwithstanding
any of the foregoing paragraphs of this Section 3.17, the Special Servicer shall not be obligated to accept the highest
cash offer for a Defaulted Loan if the Special Servicer determines (in consultation with the Controlling Class Representative
(unless a Consultation Termination Event exists or a Serviced Outside Controlled Loan Combination is involved or an Excluded Mortgage
Loan is involved), the Operating Advisor (if an Operating Advisor Consultation Trigger Event exists) and any related Outside Controlling
Note Holder (if a Serviced Outside Controlled Loan Combination is involved)), in accordance with the Servicing Standard, that
rejection of such offer would be in the best interests of the Certificateholders and, in the case of a Serviced Pari Passu Loan
Combination, the related Serviced Pari Passu Companion Loan Holder(s) (as a collective whole as if such Certificateholders and,
if applicable, any related Serviced Pari Passu Companion Loan Holder(s) 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 its reasonable and
good faith judgment, that acceptance of such offer would be in the best interests of the Certificateholders and, in the case of
a Serviced Pari Passu Loan Combination, any related Serviced Pari Passu Companion Loan Holder(s) (as a collective whole as if
such Certificateholders and, if applicable, the related Serviced Pari Passu Companion Loan Holder(s) constituted a single lender)
(for example, if the prospective buyer making the lower offer is more likely to perform its obligations or the terms offered by
the prospective buyer making the lower offer are more favorable).


 


Notwithstanding
any of the foregoing paragraphs of this Section 3.17, the Special Servicer shall not be obligated to accept the highest
cash offer for an REO Property (other than an REO Property related to an Outside Serviced Mortgage Loan) if the Special Servicer
determines


 






    	-253- 



     


    

 


(in consultation with the related Directing Holder (unless, if the Controlling Class Representative is the related
Directing Holder, a Consultation Termination Event exists or an Excluded Mortgage Loan is involved) and the Operating Advisor
(if an Operating Advisor Consultation Trigger Event exists)), in accordance with the Servicing Standard, that rejection of such
offer would be in the best interests of the Certificateholders and, in the case of an REO Property that corresponds to a Serviced
Loan Combination, the related Serviced Companion Loan Holder(s) (as a collective whole as if such Certificateholders and, if applicable,
any Serviced Companion Loan Holder(s) constituted a single lender (and, in the case of a Serviced AB Loan Combination, taking
into account the subordinate nature of the related Subordinate Companion Loan(s))), and the Special Servicer may accept a lower
cash offer (from any Person other than itself or an Affiliate) if it determines, in its reasonable and good faith judgment,
that acceptance of such offer would be in the best interests of the Certificateholders and, in the case of an REO Property that
corresponds to a Serviced Loan Combination, any related Serviced Companion Loan Holder(s) (as a collective whole as if such Certificateholders
and, if applicable, any related Serviced Companion Loan Holder(s) constituted a single lender (and, in the case of a Serviced
AB Loan Combination, taking into account the subordinate nature of the related Serviced Subordinate Companion Loan(s))) (for example,
if the prospective buyer making the lower offer is more likely to perform its obligations or the terms offered by the prospective
buyer making the lower offer are more favorable).


 


(n)         In
no event shall the Trust Fund or the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer on the
Trust’s behalf purchase, or pay or advance costs to purchase, any Outside Serviced Mortgage Loan, or any Companion Loan
or any Mortgage Loan.


 


(o)         Notwithstanding
anything herein to the contrary, any party identified in the related Co-Lender Agreement or Outside Servicing Agreement (which,
if the identified party is the holder of an Outside Serviced Mortgage Loan, shall mean the Controlling Class Representative
for so long as no Control Termination Event has occurred and is continuing), in its individual capacity and not on behalf of the
Trust, shall be entitled to purchase an Outside Serviced Mortgage Loan in accordance with the terms and conditions set forth in
the related Co-Lender Agreement and Outside Servicing Agreement. In no event shall the Trust Fund or the Trustee, the Master Servicer
or the Special Servicer on its behalf purchase, or pay or advance costs to purchase, any Outside Serviced Mortgage Loan or the
related Companion Loan(s) or any other Mortgage Loan.


 


(p)         Notwithstanding
anything to the contrary herein, any purchase or sale of a Specially Serviced Loan pursuant to this Section 3.17 will
remain subject to the cure, purchase and other rights of, in each case if applicable, any related Subordinate Companion Loan Holder
as set forth in the related Co-Lender Agreement and any holder of a related mezzanine loan as set forth in the related intercreditor
agreement. The Special Servicer shall determine the price to be paid in accordance with the terms of the related Co-Lender Agreement
or the related mezzanine loan intercreditor agreement in connection with any such purchase rights in favor of any related Subordinate
Companion Loan Holder or mezzanine loan holder and shall provide such notices to the related Subordinate Companion Loan Holder
or the holder of a related mezzanine loan as are required by the related Co-Lender Agreement or the related mezzanine loan intercreditor
agreement in connection with each such holders’ purchase rights.

Class Representative and each related Serviced Pari Passu Companion Loan Holder will be permitted to submit an offer to purchase,
and any such party is permitted to be the purchaser at any sale of, the subject Defaulted Serviced Loan Combination unless such
Person is the related Mortgagor or an agent or Affiliate of the related Mortgagor.


 


(r)          With
respect to any Serviced Pari Passu Loan Combination that is a Serviced Outside Controlled Loan Combination, the parties hereto
acknowledge that the related Co-Lender Agreement provides that if such Serviced Pari Passu Loan Combination becomes a Defaulted
Serviced Loan Combination, and if the Special Servicer determines to sell the related Serviced Mortgage Loan in accordance with
this Section 3.17, then the Special Servicer will be required to sell the related Serviced Pari Passu Companion Loan

holder of each related non-controlling Serviced Pari Passu Companion Loan, to the extent permitted under the terms of the
related Co-Lender Agreement): (a) at least 15 Business Days’ prior written notice of any decision to attempt to sell

With
respect to each Serviced AB Loan Combination, if such Serviced AB Loan Combination becomes a Defaulted Serviced Loan Combination,
and if the Special Servicer determines to sell the related Serviced Mortgage Loan in accordance with this Section 3.17,
then the Special Servicer shall not be permitted or required to sell any related Serviced Subordinate Companion Loan(s) together
with such Serviced Mortgage Loan and any related Serviced Pari Passu Companion Loan(s) as a single whole loan except as required
by the related Co-Lender Agreement.


 


(s)          With
respect to any Outside Serviced Mortgage Loan upon becoming a “Defaulted Mortgage Loan” (as such term or any analogous
term is defined pursuant to the terms of the applicable Outside Servicing Agreement), and with respect to any REO Property related
to an Outside Serviced Mortgage Loan, the liquidation of such Outside Serviced Mortgage Loan or such REO Property shall be administered
by the related Outside Special Servicer in accordance with the applicable Outside Servicing Agreement and the related Co-Lender

    	-256- 



     


    

 


sale of an Outside Serviced Mortgage Loan or any related REO Property pursuant to the applicable Outside Servicing
Agreement and/or the related Co-Lender Agreement shall be final and without recourse to the Trustee or the Trust, and none of
the Master Servicer, the Special Servicer, the Certificate Administrator or the Trustee shall have any liability to any Certificateholder
with respect to the purchase price for such Outside Serviced Mortgage Loan or such REO Property accepted on behalf of the Trust.
Any proceeds of such a sale received by the Trust Fund shall be promptly deposited in the Collection Account.


 


Section 3.18           Additional
Obligations of the Master Servicer; Inspections; Obligation to Notify Ground Lessors; Delivery of Certain Reports to the Serviced
Companion Loan Holder.


 


(a)          The
Master Servicer (or, with respect to Specially Serviced Loans and REO Properties, the Special Servicer) shall inspect or cause
to be inspected each Mortgaged Property that secures a Serviced Loan at such times and in such manner as are consistent with the
Servicing Standard, but in any event at least once every calendar year with respect to such Mortgaged Property relating to Serviced
Mortgage Loans with an outstanding principal balance of $2,000,000 or more and at least once every other calendar year with respect
to such Mortgaged Property relating to Serviced Mortgage Loans with an outstanding principal balance of less than $2,000,000,
in each case commencing in 2018; provided that the Master Servicer is not required to inspect any Mortgaged Property that
has been inspected by the Special Servicer during the preceding 12 months. If any Serviced Mortgage Loan or Serviced Loan Combination
becomes a Specially Serviced Loan, the related Mortgaged Property shall be inspected by the Special Servicer as soon as practicable
and thereafter at least every calendar year for so long as such condition exists. The cost of any annual inspection, or bi-annual
inspection, as the case may be, shall be borne by the Master Servicer unless the related Serviced Mortgage Loan or Serviced Loan
Combination is a Specially Serviced Loan. The Master Servicer shall reimburse the Special Servicer for the cost of any inspection
of a Specially Serviced Loan as a Property Advance (or as an expense of the Trust Fund and paid by the Master Servicer out of
the Collection Account if such Property Advance would be a Nonrecoverable Advance) and any out-of-pocket costs incurred with respect
to such inspection shall be borne by the Trust Fund. The Special Servicer or the Master Servicer, as applicable, shall prepare
or cause to be prepared a written report of each such inspection performed by it pursuant to this Section 3.18(a), and
shall, within five (5) Business Days following completion, deliver or make available a copy (in electronic format) of each such
report to (i) in the case of any such report prepared by the Special Servicer, the Master Servicer (who shall deliver or make
available such report to the Certificate Administrator) or (ii) in the case of any such report prepared by the Master Servicer
or received by the Master Servicer pursuant to clause (i) of this sentence, the Certificate Administrator (who shall post
such report to the Certificate Administrator’s Website for review by Privileged Persons in accordance with Section 4.02(a)).


 


(b)          The
Master Servicer shall, as to each Mortgage Loan (excluding an Outside Serviced Mortgage Loan) which is secured by the interest
of the related Mortgagor under a Ground Lease, even if the corresponding fee interest is encumbered, promptly (and in any event
within 60 days following the later of the Closing Date or its receipt of a copy of the Ground Lease) notify the related ground
lessor of the transfer of such Mortgage Loan to the Trust Fund pursuant to this Agreement and inform such ground lessor that any
notices of default under the related Ground


 






    	-257- 



     


    

 


Lease should thereafter be forwarded to the Master Servicer. The Master Servicer shall
forward to the Special Servicer any written notice of default under a ground lease.


 


(c)          The
Master Servicer and the Special Servicer shall each promptly prepare or cause to be prepared and deliver to each Serviced Companion
Loan Holder a written report, prepared in the manner set forth in Section 4.02, of each inspection performed by it with
respect to the related Mortgaged Property and Serviced Companion Loan related thereto.


 


(d)          The
Master Servicer is hereby authorized to exercise any rights granted under the applicable Outside Servicing Agreement in favor
of the Trust (or a party on its behalf) as the holder of each Outside Serviced Mortgage Loan to obtain information from the
related Outside Servicer (or other similar parties with an obligation to make advances) in connection with making nonrecoverability
determinations. The Master Servicer shall promptly deliver to any related Outside Servicer, upon request, such information in
the Master Servicer’s possession as the related Outside Servicer reasonably requests in order to determine whether an advance
similar to a P&I Advance would be “nonrecoverable.”


 


(e)          If
required under the related Co-Lender Agreement, the Master Servicer shall promptly deliver to each Serviced Companion Loan Holder
or provide electronically: (i) copies of operating statements and rent rolls; (ii) annual CREFC® NOI Adjustment
Worksheets (with annual operating statements as exhibits); and (iii) annual CREFC® Operating Statement Analysis
Reports, in each case prepared, received or obtained by it pursuant to this Agreement with respect to the Mortgaged Properties
securing the related Serviced Companion Loan.


 


Section 3.19           Lock-Box
Accounts, Escrow Accounts.


 


Except
with respect to the Outside Serviced Mortgage Loans, the Master Servicer shall administer each Lock-Box Account and Escrow Account
in accordance with the related Mortgage or Loan Agreement or Lock-Box Agreement, if any, and administer any letters of credit
pursuant to the related letter of credit agreement and the Loan Documents.


 


Notwithstanding
the foregoing, to the extent that any cash amounts are held in an Escrow Account or other cash collateral account and the mortgagee
under the related Loan Documents is permitted, but not required, to apply such amounts to prepay the related Mortgage Loan (or
Serviced Loan Combination), neither the Master Servicer nor the Special Servicer shall apply such amounts to prepay the Mortgage
Loan (or Serviced Loan Combination) until after the occurrence of an event of default under the Mortgage Loan that may result
in the Mortgage Loan (or Serviced Loan Combination) being accelerated or becoming a Specially Serviced Loan.


 


Section 3.20           Property
Advances.


 


(a)          Except
with respect to an Outside Serviced Mortgage Loan, the Master Servicer (or, to the extent provided in Section 3.20(b)
of this Agreement, the Trustee) shall make any Property Advances as and to the extent incidental to the performance of
its duties under this Agreement or otherwise required pursuant to the terms hereof; provided that no Property Advances
shall be made with regard to a Subordinate Companion Loan if the related Mortgage Loan is no longer held by the Trust. The
Special Servicer shall give the Master Servicer, the Trustee and any affected Serviced Companion Loan Holder not less than
five (or, in the case of Emergency


 






    	-258- 



     


    

 


Advances pursuant to Section 3.20(e) of this Agreement, two) Business Days’ written notice
before the date on which the Master Servicer is requested to make any Property Advance with respect to a given Specially Serviced
Loan or REO Property (other than an REO Property related to an Outside Serviced Mortgage Loan). In addition, the Special Servicer
shall provide the Master Servicer, the Trustee and any affected Serviced Companion Loan Holder with such information in its possession
as the Master Servicer, the Trustee or such Serviced Companion Loan Holder, as applicable, may reasonably request to enable the
Master Servicer or the Trustee, as applicable, to determine whether a requested Property Advance would constitute a Nonrecoverable
Advance. Any such notice by the Special Servicer to the Master Servicer of a required Property Advance shall be deemed to be a
determination by the Special Servicer that such requested Property Advance is not a Nonrecoverable Advance, and the Master Servicer
shall be entitled to conclusively rely on such determination. In the absence of a determination by the Special Servicer that a
Property Advance is a Nonrecoverable Advance, all determinations of recoverability with respect to Property Advances to be made
(or contemplated to be made) by the Master Servicer or the Trustee will remain with the Master Servicer or the Trustee, as applicable.
On the fourth Business Day before each Distribution Date, the Special Servicer shall report to the Master Servicer the Special
Servicer’s determination as to whether any Property Advance previously made with respect to a Specially Serviced Loan is
a Nonrecoverable Advance promptly after making such determination. The Master Servicer and the Trustee shall be entitled to conclusively
rely on and shall be bound by such a determination and shall be bound by a determination by the Special Servicer that a Property
Advance previously made or contemplated to be made with respect to a Specially Serviced Loan is or would be a Nonrecoverable Advance.
Although the Special Servicer may determine whether a Property Advance is a Nonrecoverable Advance, the Special Servicer will
have no right to (i) make an affirmative determination that any Property Advance previously made or to be made (or contemplated
to be made) by the Master Servicer or the Trustee is, or would be, recoverable or (ii) reverse any determination that may have
been made by the Master Servicer or the Trustee or to prohibit the Master Servicer or the Trustee from making a determination
that any Property Advance constitutes or would constitute a Nonrecoverable Advance; provided that this sentence will not be construed
to limit the Special Servicer’s right to make a determination that a Property Advance to be made (or contemplated to be
made) would be, or a previously made Advance is, a Nonrecoverable Advance, as described in this Section 3.20. The Master
Servicer and the Special Servicer shall consider Unliquidated Advances in respect of prior Property Advances for the purposes
of non-recoverability determinations as if such amounts were unreimbursed Property Advances.


 


For
purposes of distributions to Certificateholders and Serviced Companion Loan Holders and compensation to the Master Servicer or
the Trustee, Property Advances shall not be considered to increase the principal balance of any Mortgage Loan or Serviced Loan
Combination, notwithstanding that the terms of such Mortgage Loan or Serviced Loan Combination so provide.


 


(b)          The
Master Servicer shall notify the Trustee, the Special Servicer and any related Serviced Companion Loan Holder in writing promptly
upon, and in any event within one (1) Business Day after, becoming aware that it will be unable to make any Property Advance required
to be made pursuant to the terms hereof, and in connection therewith, shall set forth in such notice the amount of such Property
Advance, the Person to whom it will be paid, and the circumstances and purpose of such Property Advance, and shall set forth therein
information and instructions for the payment of such Property Advance, and, on the date specified in such notice


 






    	-259- 



     


    

 


for
the payment of such Property Advance, or, if the date for payment has passed or if no such date is specified, then within
five (5) Business Days following such notice, the Trustee, subject to the provisions of Section 3.20(c) of this
Agreement, shall pay the amount of such Property Advance in accordance with such information and instructions. Any notice to
the Trustee pursuant to this Section shall be deemed to be given to a Responsible Officer of the Trustee if made in
accordance with Section 12.04 of this Agreement.


 


(c)          None
of the Master Servicer, the Special Servicer or the Trustee shall be obligated to make a Property Advance as to any Mortgage Loan
or Serviced Loan Combination or REO Property if the Master Servicer, the Special Servicer or the Trustee, as applicable, determines
that such Advance will be a Nonrecoverable Advance. The determination by any Person with an obligation hereunder to make Property
Advances that it has made a Nonrecoverable Advance or that any proposed Property Advance, if made, would constitute a Nonrecoverable
Advance or a determination by the Special Servicer that a Property Advance previously made or proposed to be made is or would,
if made, constitute a Nonrecoverable Advance, shall be made by such Person (i) in the case of the Master Servicer or the
Special Servicer, in accordance with the Servicing Standard and (ii) in the case of the Trustee, in accordance with its good
faith business judgment and shall be evidenced by an Officer’s Certificate delivered on or prior to the next Master Servicer
Remittance Date to (1) the affected Serviced Companion Loan Holders or their Companion Loan Holder representatives (and the related
master servicer and special servicer under any related Other Pooling and Servicing Agreement, if applicable), in the case of any
Serviced Loan Combination, (2) the Trustee (unless it is the Person making the determination), (3) the Controlling Class Representative
(prior to the occurrence and continuance of a Control Termination Event), (4) in the case of a Property Advance with respect to
any Serviced Outside Controlled Loan Combination, the related Outside Controlling Note Holder, (5) the Master Servicer (unless
it is the Person making the determination), (6) the Special Servicer (unless it is the Person making the determination), and (7)
the Depositor (if the Trustee is making the determination), setting forth the basis for such determination, together with any
other information that supports such determination together with a copy of any Appraisal of the related Mortgaged Property or
REO Property, as the case may be (which Appraisal shall be an expense of the Trust Fund, shall take into account any material
change in circumstances of which such Person is aware or such Person has received new information, either of which has a material
effect on the value and shall have been conducted in accordance with the standards of the Appraisal Institute within the twelve
months preceding such determination of nonrecoverability), and further accompanied by related Mortgagor operating statements and
financial statements, budgets and rent rolls of the related Mortgaged Property (to the extent available and/or in such Person’s
possession) and any engineers’ reports, environmental surveys or similar reports that such Person may have obtained and
that support such determination. In connection with a determination by the Special Servicer, the Master Servicer or the Trustee
as to whether a Property Advance previously made or to be made constitutes or would constitute a Nonrecoverable Advance:


 


(A)          any
such Person will be entitled to consider (among other things) the obligations of the Mortgagor under the terms of the related
Mortgage Loan or Serviced Loan Combination as it may have been modified, to consider (among other things) the related Mortgaged
Properties in their “as is” or then current conditions and occupancies, as modified by such party’s assumptions
regarding the possibility and effects of future adverse change with respect to such Mortgaged


 






    	-260- 



     


    

 


Properties, to estimate and consider
(among other things) future expenses and to estimate and consider (among other things) the timing of recoveries;


 


(B)          any
such Person may update or change its recoverability determinations at any time (but not reverse any other Person’s determination
that an Advance is a Nonrecoverable Advance) and may obtain at the expense of the Trust Fund any analysis, Appraisals or market
value estimates or other information as reasonably may be required for such purposes;


 


(C)          the
Special Servicer may, at its option, make a determination in accordance with the Servicing Standard that any proposed Property
Advance, if made, would be a Nonrecoverable Advance or that any outstanding Property Advance is a Nonrecoverable Advance and may
deliver to the Master Servicer, the Trustee, the Controlling Class Representative (prior to the occurrence and continuance of
a Consultation Termination Event) and, in the case of a Property Advance with respect to a Serviced Outside Controlled Loan Combination,
the related Outside Controlling Note Holder notice of such determination, which determination shall be conclusive and binding
on the Master Servicer and the Trustee (but this statement shall not be construed to entitle the Special Servicer to reverse any
other authorized Person’s determination, or to prohibit any such other authorized Person from making a determination, that
a Property Advance constitutes or would constitute a Nonrecoverable Advance);


 


(D)          the
Trustee shall be entitled to rely, conclusively, on any determination by the Master Servicer or Special Servicer that a Property
Advance is or, if made, would be a Nonrecoverable Advance, and the Master Servicer shall be entitled to rely, conclusively, on
any determination by the Special Servicer that a Property Advance is or, if made, would be a Nonrecoverable Advance;


 


(E)          any
non-recoverability determination by the Master Servicer or the Special Servicer pursuant to this Section 3.20 with
respect to the non-recoverability of Property Advances shall be conclusive and binding on the Master Servicer (in the case of
such a determination by the Special Servicer) and the Trustee; and


 


(F)          notwithstanding
the foregoing, the Trustee may conclusively rely upon any determination by the Master Servicer or the Special Servicer that any
Property Advance would be recoverable (unless a non-recoverability determination has been made by the other servicer in accordance
with clause (E) above which is binding on the Trustee), and the Master Servicer may conclusively rely upon any determination
by the Special Servicer that any Property Advance would be recoverable.


 


(d)          The
Master Servicer, the Special Servicer and/or the Trustee, as applicable, shall be entitled to the reimbursement of Property Advances
made by any of them to the extent permitted pursuant to Section 3.06(a)(ii) or Section 3.06A(a)(ii) of this
Agreement, together with any related Advance Interest Amount in respect of such Property Advances, and the Master Servicer and
the Special Servicer, as applicable, hereby covenant and agree to use efforts consistent


 






    	-261- 



     


    

 


with the Servicing Standard to obtain
the reimbursement of such Property Advances from the related Mortgagors to the extent permitted by applicable law and the related
Loan Documents.


 


(e)          Notwithstanding
anything to the contrary contained in this Agreement, if a Property Advance is required to be made under this Agreement with respect
to any Specially Serviced Loan or REO Property (other than an REO Property related to an Outside Serviced Mortgage Loan), the
Special Servicer shall request that the Master Servicer make such Property Advance, such request to be made, in writing, at least
five (5) Business Days (or, in the case of an Emergency Advance, two (2) Business Days, provided that the written
request sets forth the nature of the emergency or the basis of the urgency) in advance of the date on which such Property
Advance is required to be made hereunder and to be accompanied by such information and documentation regarding the subject Property
Advance as the Master Servicer may reasonably request, subject to the Master Servicer’s right to determine that such Property
Advance does not constitute or would not constitute a Nonrecoverable Advance. The Master Servicer shall have the obligation to
make any such Property Advance that it is so requested by the Special Servicer to make, within five (5) Business Days (or,
in the case of an Emergency Advance, two (2) Business Days) of the Master Servicer’s receipt of such request. The Special
Servicer shall have no obligation to make any Property Advance; provided that the Special Servicer may in its sole discretion
elect to make an Emergency Advance, and the Master Servicer shall reimburse the Special Servicer for such Property Advance (with
interest thereon), provided that such Advance is not determined by the Master Servicer, in accordance with the Servicing Standard,
to be nonrecoverable. The Master Servicer shall be entitled to reimbursement for any Advance made by it at the direction of the
Special Servicer, together with interest thereon at the same time, in the same manner and to the same extent as the Master Servicer
is entitled with respect to any other Advances made thereby.


 


(f)          Within
five (5) Business Days of making an Emergency Advance pursuant to the proviso to the penultimate sentence of Section 3.20(e),
the Special Servicer shall deliver to the Master Servicer a request for reimbursement for such Emergency Advance, along with
all information and documentation regarding the subject Emergency Advance as the Master Servicer may reasonably request, and
the Master Servicer shall be obligated, out of such Master Servicer’s own funds, to reimburse the Special Servicer for
any such unreimbursed Emergency Advances (other than any Emergency Advance determined by the Master Servicer, in accordance
with Section 3.20(c) of this Agreement, to be a Nonrecoverable Property Advance) made by the Special Servicer pursuant
to the proviso to the penultimate sentence of Section 3.20(e), together with interest thereon at the Advance Rate
from the date made to, but not including, the date of reimbursement. Such reimbursement and any accompanying payment of
interest shall be made within five (5) Business Days of the written request therefor pursuant to the preceding sentence by
wire transfer of immediately available funds to an account designated in writing by the Special Servicer. Upon the Master
Servicer’s reimbursement to the Special Servicer of any Emergency Advance and payment to the Special Servicer of
interest thereon, all in accordance with this Section 3.20(f), the Master Servicer shall for all purposes of this
Agreement be deemed to have made such Emergency Advance at the same time as the Special Servicer actually made such Emergency
Advance, and accordingly, the Master Servicer shall be entitled to be reimbursed for such Emergency Advance, together with
interest thereon at the Advance Rate, at the same time, in the same manner and to the same extent as the Master Servicer
would otherwise have been entitled if it had actually made such Emergency Advance at the time the Special Servicer
did.


 






    	-262- 



     


    

 


Notwithstanding the foregoing provisions of this Section 3.20(f), the Master Servicer shall not
be required to reimburse the Special Servicer for any Emergency Advance if the Master Servicer determines in accordance with Section
3.20(c) of this Agreement that such Emergency Advance, although not characterized by the Special Servicer as a Nonrecoverable
Property Advance, is in fact a Nonrecoverable Property Advance. The Master Servicer shall notify the Special Servicer in writing
of such determination and, if applicable, such Nonrecoverable Property Advance shall be reimbursed to the Special Servicer pursuant
to Section 3.06(a) of this Agreement.

(B)          the
most current rent roll and income or operating statement available for the related Mortgaged Properties;


 


(C)          the
Special Servicer’s recommendations on how the related Mortgage Loan might be returned to performing status or otherwise

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;


 


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


 


(vii)       such
other information as the Special Servicer deems relevant in light of the proposed or taken action and the Servicing Standard.


 


If
any related Outside Controlling Note Holder (if a Serviced Outside Controlled Loan Combination is involved) or the Controlling
Class Representative (if any other Serviced Loan(s), except for Excluded Mortgage Loans, are involved and a Control Termination
Event does not exist), as applicable, does not disapprove an Asset Status Report in writing within 10 Business Days of receiving
such Asset Status Report, then the related Directing Holder shall be deemed to have approved such Asset Status Report and the
Special Servicer shall implement the recommended action as outlined in such Asset Status Report; provided, however,
that the Special


 






    	-264- 



     


    

 


Servicer
may not take any action that is contrary to applicable law, the Servicing Standard or the terms of the applicable Loan
Documents. If the related Directing Holder disapproves such Asset Status Report within 10 Business Days of receipt (and, if
the Controlling Class Representative is the related Directing Holder, a Control Termination Event does not exist and such
Asset Status Report does not relate to an Excluded Mortgage Loan) and the Special Servicer has not made the affirmative
determination contemplated below, the Special Servicer will revise such Asset Status Report and deliver to the Operating
Advisor (subject to Section 3.21(e) of this Agreement), the related Directing Holder (but, if the Controlling Class
Representative is the related Directing Holder, only prior to the occurrence and continuance of a Consultation Termination
Event and only if such Asset Status Report does not relate to an Excluded Mortgage Loan), any related Serviced Companion Loan
Holder(s) (in the case of a Serviced Loan Combination) and, for posting to the Rule 17g-5 Information Provider’s
Website pursuant to Section 12.13 of this Agreement, the Rule 17g-5 Information Provider a new Asset Status Report as
soon as practicable, but in no event later than 30 days after such disapproval. The Special Servicer shall revise such
Asset Status Report as described above until the related Directing Holder (but, if the Controlling Class Representative is
the related Directing Holder, only if a Control Termination Event does not exist and only if an Excluded Mortgage Loan is not
involved) shall fail to disapprove such revised Asset Status Report in writing within 10 Business Days of receiving such
revised Asset Status Report or until the Special Servicer makes a determination, consistent with the Servicing Standard, that
such objection is not in the best interests of all the Certificateholders and, if applicable, the related Serviced Companion
Loan Holder(s) (as a collective whole as if such Certificateholders, and/or Serviced Companion Loan Holder(s), if applicable,
constitute a single lender (and, in the case of a Serviced AB Loan Combination, taking into account the subordinate nature of
the related Subordinate Companion Loan)). The Special Servicer may, from time to time, modify any Asset Status Report it has
previously delivered and implement such report, provided such report shall have been prepared, reviewed and not
rejected pursuant to the terms of this Section. If the related Directing Holder does not approve an Asset Status Report
within 60 Business Days from the first submission thereof, the Special Servicer shall take such action as directed by the
related Directing Holder (but, if the Controlling Class Representative is the related Directing Holder, only if a Control
Termination Event does not exist and only if an Excluded Mortgage Loan is not involved), provided such action does not
violate the Servicing Standard (or, if such action would violate the Servicing Standard, the Special Servicer shall take such
action as was reflected in the most recent Asset Status Report prepared by the Special Servicer with respect to the subject
Serviced Loan that is consistent with the Servicing Standard). Notwithstanding the foregoing, if the Special
Servicer determines that emergency action is necessary to protect the related Mortgaged Property or the interests of the
Certificateholders and any related Serviced Companion Loan Holder(s), or if a failure to take any such action at such time
would be inconsistent with the Servicing Standard, the Special Servicer may take actions with respect to the related
Mortgaged Property before the expiration of a 10 Business Day period if the Special Servicer reasonably determines in
accordance with the Servicing Standard that failure to take such actions before the expiration of a 10 Business Day period
would materially and adversely affect the interest of the Certificateholders and any related Serviced Companion Loan
Holder(s) (if applicable) and the Special Servicer has made a reasonable effort to contact the related Directing Holder
(during the period that such Directing Holder has approval rights); provided that the foregoing shall not relieve the
Special Servicer of its duties to comply with the Servicing Standard. If the Special Servicer acts or intends to act in
accordance with either of the prior two sentences, then the Special Servicer shall act in accordance with the most recent
Asset Status Report provided by the Special Servicer with respect to the


 






    	-265- 



     


    

 


subject Serviced Loan that is consistent
with the Servicing Standard and such Asset Status Report shall be deemed a Final Asset Status Report. To the extent that the Special
Servicer received notice of an Excluded Controlling Class Mortgage Loan (in the form of Exhibit M-1C or M-1F), any
Asset Status Report or Excluded Information delivered with respect to an Excluded Controlling Class Mortgage Loan shall be labeled
by the Special Servicer with “Excluded Information” followed by the loan number and loan name.


 


After
the occurrence and during the continuance of an Operating Advisor Consultation Trigger Event, the Special Servicer shall consult
on a non-binding basis with the Operating Advisor in connection with each Asset Status Report prior to finalizing and executing
such Asset Status Report and the Operating Advisor shall propose, by written notice, alternative courses of action within 10 Business
Days of receipt of each Asset Status Report to the extent the Operating Advisor determines such alternatives to be in the best
interest of the Certificateholders (including any Certificateholders that were previously included in the Control Eligible Classes),
as a collective whole as if such Certificateholders constituted a single lender. In addition, after the occurrence and during
the continuance of a Control Termination Event, but prior to the occurrence and continuance of a Consultation Termination Event,
the Special Servicer shall also consult on a non-binding basis with the Controlling Class Representative in connection with each
related Asset Status Report (other than any Asset Status Report with respect to an Excluded Mortgage Loan) prior to finalizing
and executing such Asset Status Report and the Controlling Class Representative shall be permitted to propose alternative courses
of action within 10 Business Days of receipt of each Asset Status Report (other than any Asset Status Report with respect
to an Excluded Mortgage Loan). Furthermore, with respect to a Serviced Loan Combination, at all times if and to the extent so
provided in the related Co-Lender Agreement, any related Serviced Pari Passu Companion Loan Holder (or its Companion Loan Holder
Representative) shall be entitled to consult on a non-binding basis with the Special Servicer and propose alternative courses
of action in respect of any Asset Status Report within 10 Business Days of receiving such Asset Status Report; provided
that, in the case of a Serviced Outside Controlled Loan Combination, a related Serviced Pari Passu Companion Loan Holder (or its
Companion Loan Holder Representative) may be the related Outside Controlling Note Holder. The Special Servicer shall consider
any such proposals from (a) the Operating Advisor (during the continuance of an Operating Advisor Consultation Trigger Event),
(b) the Controlling Class Representative (during the continuance of a Control Termination Event but prior to the occurrence and
continuance of a Consultation Termination Event and only with respect to any Serviced Loan that is not an Excluded Mortgage Loan)
or (c) with respect to any Serviced Companion Loan, any related Serviced Pari Passu Companion Loan Holder (or its Companion Loan
Holder Representative) (if and when provided in the related Co-Lender Agreement), as applicable, and determine whether any changes
to its proposed Asset Status Report should be made, such determination being made in accordance with the Servicing Standard and
the other terms of this Agreement, but the Special Servicer will be under no obligation to revise such Asset Status Report based
on the input or comments of the Operating Advisor or (during the continuance of a Control Termination Event) the Controlling Class
Representative or, with respect to any Serviced Companion Loan and subject to the related Co-Lender Agreement, any related Serviced
Pari Passu Companion Loan Holder (or its Companion Loan Holder Representative). In the event that the Operating Advisor, the Controlling
Class Representative, the related Serviced Companion Loan Holder (or its Companion Loan Holder Representative), or the related
Outside Controlling Note Holder, as applicable, does not propose alternative courses of action within


 






    	-266- 



     


    

 


10 Business Days after
receipt of such Asset Status Report, the Special Servicer shall implement the Asset Status Report as proposed by the Special Servicer.


 


After
the occurrence and during the continuance of a Control Termination Event, the Controlling Class Representative shall have no right
to consent or object to any Asset Status Report under this Section 3.21(b). After the occurrence and during the continuance
of a Control Termination Event but prior to the occurrence of a Consultation Termination Event, the Controlling Class Representative,
and after the occurrence and during the continuance of an Operating Advisor Consultation Trigger Event, the Operating Advisor,
will be entitled to consult on a non-binding basis with the Special Servicer and propose alternative courses of action and provide
other feedback in respect of any Asset Status Report. The Special Servicer may choose to revise the Asset Status Report as it
deems reasonably necessary in accordance with the Servicing Standard to take into account any input and/or recommendations of
the Operating Advisor after the occurrence and during the continuance of an Operating Advisor Consultation Trigger Event or the
Controlling Class Representative after the occurrence and during the continuance of a Control Termination Event but prior to the
occurrence of a Consultation Termination Event, but is under no obligation to follow any particular recommendation of the Operating
Advisor or Controlling Class Representative. From and after the Closing Date, the Controlling Class Representative shall have
no right to receive any Asset Status Report related to an Excluded Mortgage Loan or otherwise to consent or object thereto under
this Section 3.21(b) or consult with the Special Servicer with respect to any matter set forth therein.


 


With
respect to a Servicing Shift Loan Combination that is a Serviced Outside Controlled Loan Combination, prior to the related Servicing
Shift Date, no request for approval of the Controlling Class Representative shall be made on any matter related to such Servicing
Shift Loan Combination, nor shall the Controlling Class Representative have the right to approve Asset Status Reports related
to such Servicing Shift Loan Combination, except that the Controlling Class Representative (prior to the occurrence and continuance
of a Consultation Termination Event and only if the related Servicing Shift Mortgage Loan is not an Excluded Mortgage Loan) may
exercise the consultation rights, if any, of the holder of the related Servicing Shift Mortgage Loan with respect to Asset Status
Reports, Major Decisions and any proposed sale of such Servicing Shift Mortgage Loan set forth in the applicable Co-Lender Agreement.
With respect to a Servicing Shift Loan Combination that is a Serviced Outside Controlled Loan Combination and any related REO
Property, prior to the related Servicing Shift Date, the Outside Controlling Note Holder with respect to such Servicing Shift
Loan Combination shall exercise all approval rights regarding any Asset Status Report in respect of such Servicing Shift Loan
Combination or REO Property set forth in the second paragraph of this Section 3.21(b) without regard to the occurrence
of any Control Termination Event or Consultation Termination Event. Notwithstanding the foregoing, after the occurrence and during
the continuance of an Operating Advisor Consultation Trigger Event, the Operating Advisor will be entitled to consult on a non-binding
basis with the Special Servicer and propose alternative courses of action and provide other feedback in respect of any Asset Status
Report, Major Decisions and any proposed sale of such Servicing Shift Mortgage Loan while it is serviced hereunder. The Special
Servicer may choose to revise the Asset Status Report as it deems reasonably necessary in accordance with the Servicing Standard
to take into account any input and/or recommendations of the Operating Advisor after the occurrence and during the continuance
of an Operating Advisor Consultation Trigger Event or the Controlling Class Representative after the occurrence and during the
continuance of a Control Termination


 






    	-267- 



     


    

 


Event but prior to the occurrence of a Consultation Termination Event, but is under no obligation
to follow any particular recommendation of the Operating Advisor or Controlling Class Representative.


 


(c)          Subject
to Section 3.21(b) of this Agreement, during the continuance of a Servicing Transfer Event, the Special Servicer shall
have the authority to meet with the related Mortgagors and take any actions consistent with the Servicing Standard and the most
recent Asset Status Report for the related Mortgage Loan.


 


(d)          Upon
request of any Certificateholder (or any Certificate Owner, if applicable, which shall have provided the Certificate Administrator
with an Investor Certification), the Certificate Administrator shall mail, without charge, to the address specified in such request
a copy of the summary of the Final Asset Status Report for each Specially Serviced Loan; provided that an Excluded Controlling
Class Holder shall not be provided with any Final Asset Status Report (or copy thereof) or the summary of any Final Asset Status
Report (or copy thereof) with respect to any Excluded Controlling Class Mortgage Loan with respect to which such Excluded Controlling
Class Holder is a Borrower Party.


 


(e)          Prior
to the occurrence and continuance of an Operating Advisor Consultation Trigger Event, the Special Servicer shall deliver to the
Operating Advisor only each related Final Asset Status Report.


 


(f)          With
respect to any Asset Status Report provided to the Operating Advisor pursuant to this Section 3.21, the Special Servicer
shall make available to the Operating Advisor one or more Servicing Officers with relevant knowledge regarding the applicable
Mortgage Loan and such Asset Status Report in order to address reasonable questions that the Operating Advisor may have relating
to, among other things, such Asset Status Report and potential conflicts of interest with respect to such Asset Status Report.


 


(g)          Notwithstanding
the foregoing, the Special Servicer shall not follow any advice, direction or consultation provided by the Operating Advisor,
any Serviced Companion Loan Holder, any Companion Loan Holder Representative or the related Directing Holder that would require
or cause the Special Servicer to violate any applicable law, be inconsistent with the Servicing Standard, require or cause the
Special Servicer to violate provisions of this Agreement or the REMIC Provisions, require or cause the Special Servicer to violate
the terms of any Mortgage Loan or Serviced Loan Combination, any related Loan Documents, any related Co-Lender Agreement or any

the rights and remedies against such Mortgage Loan Seller pursuant to this Agreement or the related Mortgage Loan Purchase Agreement
with respect to any Material Defect) or any party to this Agreement or their respective Affiliates, officers, directors, employees
or agents to any claim, suit or liability, cause either Trust REMIC to fail to qualify as a REMIC or the Grantor Trust to fail
to qualify as a grantor trust for federal income tax purposes, result in the imposition of a “prohibited transaction”
or “prohibited contribution” tax under the REMIC Provisions, materially expand the scope of any Special Servicer’s
responsibilities under this Agreement or any Co-Lender Agreement, or cause the Special Servicer to act, or fail to act, in a manner
that in the reasonable judgment of the Special Servicer is not in the best interests of the Certificateholders and/or the Serviced
Companion Loan


 






    	-268- 



     


    

 


Holders. In addition, the Special Servicer is under no obligation to act upon any recommendation of the Operating
Advisor.


 


(h)         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 (for the purposes of this clause (l), “Applicable
Laws”), the Special Servicer may be required to obtain, verify and record certain information relating to individuals
and entities which maintain a business relationship with the Special Servicer. Accordingly, each of the parties hereto agrees
to provide to the Special Servicer, upon its reasonable request, from time to time such identifying information and documentation
as may be readily available to such party in order to enable the Special Servicer to comply with Applicable Laws; provided that
the Special Servicer shall be responsible for all reasonable actual out-of-pocket expenses incurred by such party in connection

became a Specially Serviced Loan and in any event shall continue to act as Master Servicer and administrator of such Serviced
Loan until the Special Servicer has commenced the servicing of such Serviced Loan, which shall occur upon the receipt by the Special
Servicer of the Servicing File. With respect to each such Serviced Loan that becomes a Specially Serviced Loan, the Master Servicer
shall instruct the related Mortgagor to continue to remit all payments in respect of such Serviced Loan to the Master Servicer.
The Master Servicer shall forward any notices it would otherwise send to the Mortgagor of such a Specially Serviced Loan to the

the Master Servicer, such Serviced Loan shall cease to be a Specially Serviced Loan in accordance with the first proviso of the
definition of Specially Serviced Loans, the Special Servicer’s obligation to service such Serviced Loan shall terminate
and the obligations of the Master Servicer to service and administer such Serviced Loan as a Serviced Loan that is not a Specially
Serviced Loan shall resume. In addition, if the related Mortgagor has been instructed, pursuant to the preceding paragraph, to
make payments to the Special Servicer, upon such determination, the Special Servicer shall instruct the related Mortgagor to remit
all payments in respect of such Specially Serviced Loan directly to the Master Servicer.


 


(b)          In
servicing any Specially Serviced Loan, the Special Servicer shall provide to the Custodian originals of documents included within

Reserve Account. The Certificate Administrator shall establish and maintain the Interest Reserve Account in the
Certificate Administrator’s name, on behalf of the Trustee, for the benefit of the Certificateholders. The Interest
Reserve Account shall be established and maintained as a non-interest bearing Eligible Account. On each Master Servicer
Remittance Date occurring in January (except during a leap year) or February (commencing in 2018) (unless, in either such
case, the related Distribution Date is the final Distribution Date), the Master Servicer shall remit to the Certificate
Administrator for deposit into the Interest Reserve Account, in respect of all the Mortgage Loans that accrue interest on the
basis of a 360-day year and the actual number of days in the related month, an amount equal to one day’s interest at
the related Net Mortgage Rate on the Stated Principal Balance of each such Mortgage Loan as of the close of business on the
Distribution Date in the month preceding the month in which such Master Servicer Remittance Date occurs, to the extent a
Monthly Payment or P&I Advance is made in respect thereof (all amounts so deposited in any consecutive January (if
applicable) and February, “Withheld Amounts”). On or prior to the Master Servicer Remittance Date in March
(or February if the final Distribution Date occurs in such month) of each calendar year (commencing in 2018), the Certificate

Waivers, Amendments and Other Actions.

to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under subpart E, part I of subchapter J
of the Code for federal income tax purposes or (2) result in the imposition of a tax upon either Trust REMIC or the Trust

definition of “Special Servicer Decision”) shall obtain the consent of the Special Servicer, and, in each case, to
the extent any modification, waiver, amendment or other action constitutes a Major Decision, the Special Servicer shall obtain
the consent of the related Outside Controlling Note Holder (if a Serviced Outside Controlled Loan Combination is involved) or the

Control Termination Event does not exist), as applicable, in accordance with Section 6.09(a) of this Agreement and shall
consult with the Operating Advisor (to the extent required pursuant to Section 3.29, Section 6.09 or this Section
3.24). With respect to any modification, waiver, amendment, consent or other action that constitutes a Major Decision with
regard to any Serviced Loan, the Special Servicer shall also obtain the consent of the related Outside Controlling Note Holder

waiver, amendment, consent or other action that constitutes a Major Decision or a Special Servicer Decision, shall refer the request
to the Special Servicer, and the Special Servicer shall process the request directly or, if mutually agreed to by the Special Servicer
and the Master Servicer, the Master Servicer shall process such request (provided that, the Master Servicer shall, without the

or (ii) of clause (e) of the definition of “Special Servicer Decision” with respect to any Performing Serviced Loan)
subject to the consent of the Special Servicer as set forth below.


 


When the Special Servicer’s
consent is required with respect to any modification, waiver, amendment, consent or other action that is a Major Decision or a
Special Servicer Decision with respect to a Performing Serviced Loan (i.e., when (x) the Master Servicer and Special Servicer
have mutually agreed that the Master Servicer shall process such modification, waiver or amendment with respect to a Performing
Serviced Loan or (y) the Master Servicer is processing any Special Servicer Decision described in clause (b), clause (c) or subclause
(i) or (ii) of clause (e) of the definition of “Special Servicer Decision” with respect to any Performing Serviced
Loan, in each case, as set forth in the preceding paragraphs), the Master Servicer shall, in a manner consistent with the Servicing
Standard, provide the Special Servicer with written notice of any request for such modification, waiver, amendment, consent or
other action, accompanied by the Master Servicer’s written recommendation and analysis and any and all information in the
Master Servicer’s possession or reasonably available to it that the Special Servicer or, with respect to a Major Decision,
the related Directing Holder may reasonably request in order to withhold or grant its consent, and in all cases the Special Servicer
shall be entitled (subject to, with respect to Major Decision, in each case if applicable, the consultation rights of the Operating
Advisor (to the extent required pursuant to Section 3.29, Section 6.09 or this Section 3.24), the consent
and/or

consultation
rights of the related Directing Holder (to the extent required pursuant to Section 6.09 or this Section 3.24) and/or
the consultation rights of any related Serviced Companion Loan Holder or its Companion Loan Holder Representative) to approve
or disapprove such modification, waiver, amendment, consent or other action. The Special Servicer shall have 15 Business Days
(or, with respect to a Serviced Loan Combination, such longer period as required by the related Co-Lender Agreement, but in no
event less than 5 Business Days after the time period set forth in such Co-Lender Agreement for review by any related Serviced
Companion Loan Holder or its Companion Loan Holder Representative) (or 60 days with respect to an Acceptable Insurance Default),
from the date that the Special Servicer receives the Master Servicer’s written analysis and recommendation and any supporting
information it requested from the Master Servicer, to analyze and approve such modification, waiver, amendment, consent or other
action and, prior to the end of such 15 Business Day period or such longer period if required by the applicable Co-Lender Agreement
or 60-day period (with respect to an Acceptable Insurance Default), as applicable, the Special Servicer shall notify the related
Outside Controlling Note Holder (if a Serviced Outside Controlled Loan Combination is involved) or the Controlling Class Representative
(if any other Serviced Loan(s) (exclusive of any Excluded Mortgage Loan(s)) are involved and a Control Termination Event does
not exist), as applicable, of such request for approval of each such modification, waiver, amendment, consent or other action
that constitutes a Major Decision and provide its written analysis and recommendation (or, in the case of any action that constitutes
a Major Decision, the Major Decision Reporting Package) with respect thereto. Following such notice, the related Outside Controlling
Note Holder (if a Serviced Outside Controlled Loan Combination is involved) or the Controlling Class Representative (if any other
Serviced Loan(s) (exclusive of any Excluded Mortgage Loan(s)) are involved and a Control Termination Event does not exist), as
applicable, shall have 10 Business Days (or, in the case of a determination of an Acceptable Insurance Default, 20 days)
from the date it receives from the Special Servicer the recommendation and analysis of the Master Servicer or the Special Servicer
(or, in the case of any action that constitutes a Major Decision, the related Major Decision Reporting Package), as applicable,
and any other information it may reasonably request (or, with respect to a Serviced Loan Combination, such longer time period
as may be provided in the related Co-Lender Agreement) to approve any recommendation of the Special Servicer or the Master Servicer
relating to any such request for approval of modification, waiver, amendment, consent or other action that constitutes a Major
Decision. In any such event, if the related Directing Holder does not respond to a request for approval by 5:00 p.m. on the 10th
Business Day (or, with respect to a Serviced Loan Combination, such longer time period as may be provided in the related Co-Lender
Agreement) or 20th day, as applicable, after receipt of the applicable recommendation and analysis (or, in the case of any action
that constitutes a Major Decision, the related Major Decision Reporting Package) and other requested information as set forth
in the preceding sentence, the Special Servicer or the Master Servicer, as applicable, may deem its recommendation approved by
the related Directing Holder, and if the Special Servicer does not respond to a request for approval within the required 15 Business
Days (or, with respect to a Serviced Loan Combination, such longer period as required by the related Co-Lender Agreement, but
in no event less than 5 Business Days after the time period set forth in such Co-Lender Agreement for review by any related Serviced
Companion Loan Holder or its Companion Loan Holder Representative) or 60 days (with respect to an Acceptable Insurance Default),
as applicable, the Master Servicer may deem its recommendation approved by the Special Servicer.

With respect to any Performing
Serviced Loan, the Master Servicer, without the consent or consultation of the Special Servicer, the Operating Advisor and/or the
Directing Holder, shall process and determine whether to consent to or approve any request by the related Mortgagor with respect
to any action that is not (1) a Major Decision, (2) a Special Servicer Decision or (3) an action with respect to which the Special
Servicer’s consent is required pursuant to Section 3.09 of this Agreement.


 


(b)          All
modifications, waivers or amendments of any Serviced Loan shall be in writing and shall be effected in a manner consistent with
the Servicing Standard. The Master Servicer or the Special Servicer, as applicable (in each case, if it is the party processing
the related modification, waiver or amendment pursuant to Section 3.24(a)), shall notify in writing the Trustee, the Certificate
Administrator, the Depositor, any related Serviced Companion Loan Holder, any related Outside Controlling Note Holder, the Controlling
Class Representative (prior to the occurrence and continuance of a Consultation Termination Event and other than with respect to
any Excluded Mortgage Loan), the Operating Advisor and, for posting to the Rule 17g-5 Information Provider’s Website pursuant
to Section 12.13 of this Agreement, the Rule 17g-5 Information Provider, in writing, of any modification, waiver or
amendment of any term of any Serviced Loan and the date thereof, and shall deliver a copy to the Trustee, any related Serviced
Companion Loan Holder (which, in the case of a Serviced Companion Loan that has been included in an Other Securitization Trust,
shall be deemed to be the related master servicer under the related Other Pooling and Servicing Agreement, unless the notifying
party has received written notice otherwise), any related Outside Controlling Note Holder, the Controlling Class Representative
(prior to the occurrence and continuance of a Consultation Termination Event and other than with respect to any Excluded Mortgage
Loan) and the Operating Advisor and an original to the Certificate Administrator (or any Custodian appointed by it) of the recorded
agreement relating to such modification, waiver or amendment within 15 Business Days following the execution and recordation thereof.
For the avoidance of doubt, the requirement with respect to the delivery of assumption or substitution agreements shall be governed
by Section 3.09.


 


(c)          Subject
to Section 3.30 of this Agreement, any modification of any Loan Documents that requires obtaining a Rating Agency Confirmation
pursuant to such Loan Documents, or any modification that would eliminate, modify or alter the requirement of obtaining a Rating
Agency Confirmation in such Loan Documents, shall not be made without obtaining a Rating Agency Confirmation. The Rating Agency
Confirmation shall be obtained at the related Mortgagor’s expense in accordance with the related Loan Agreement or, if not
so provided in such Loan Agreement or if such Mortgagor does not pay, at the expense of the Trust Fund.


 


(d)          Promptly
after any Mortgage Loan or Serviced Loan Combination becomes a Specially Serviced Loan, the Special Servicer shall request from
the Certificate Administrator the name of the current Controlling Class Representative and, if applicable, shall request from the
Master Servicer the name of the current related Serviced Companion Loan Holder. Upon receipt of the name of such current Controlling
Class Representative from the Certificate Administrator, the Special Servicer shall notify the Controlling Class Representative
that such Mortgage Loan became a Specially Serviced Loan. Upon receipt of the name of such current related Serviced Companion Loan
Holder from the Master Servicer, the Special Servicer shall notify the related Serviced Companion Loan Holder that the related
Serviced Loan Combination became a Specially Serviced Loan. The Certificate Administrator shall be responsible for providing the
name of the


 






    	-274- 



     


    

 


current
Controlling Class Representative only to the extent the Controlling Class Representative has identified itself as such to the
Certificate Administrator; provided that if the Controlling Class Representative is determined pursuant to the proviso
in the definition of “Controlling Class Representative”, then (i) the Certificate Administrator shall determine
which Class is the Controlling Class and (ii) the Special Servicer shall request from the Certificate Administrator, and
the Certificate Administrator shall request from the Depository at the expense of the Trust, the list of Beneficial Holders of
the Controlling Class, and the Certificate Administrator shall provide such list to the Special Servicer and the Master Servicer
at the expense of the Trust Fund.


 


(e)          [Reserved]


 


(f)          The
Special Servicer or Master Servicer may, as a condition to granting any request by a Mortgagor for consent to a modification, extension,
waiver or indulgence or any other matter or thing, the granting of which is within its discretion pursuant to the terms of the
instruments evidencing or securing the related Mortgage Loan or Serviced Loan Combination and, further, pursuant to the terms of
this Agreement and applicable law, require that such Mortgagor pay to it a reasonable or customary fee for the additional services
performed in connection with such request and any related costs and expenses incurred by it; provided that the charging
of such fee would not be a “significant modification” of the Mortgage Loan within the meaning of Treasury Regulations
Section 1.860G-2(b).


 


(g)          Notwithstanding
anything set forth in this Agreement, in no event shall the Special Servicer be permitted to:


 


(i)          extend
the Maturity Date of a Serviced Loan beyond a date that is 5 years prior to the Rated Final Distribution Date; or


 


(ii)         if
the Serviced Loan is secured by a ground lease, extend the Maturity Date of such Serviced Loan beyond a date which is 20 years
or, to the extent consistent with the Servicing Standard, giving due consideration to the remaining term of the ground lease,
10 years prior to the end of the current term of such ground lease, plus any options to extend exercisable unilaterally by the
related Mortgagor.


 


(h)          In
connection with (i) the release of a Mortgaged Property or any portion of a Mortgaged Property from the lien of the related
Mortgage or (ii) the taking of a Mortgaged Property or any portion of a Mortgaged Property by exercise of the power of eminent
domain or condemnation, if the related Loan Documents require the Master Servicer or the Special Servicer, as applicable, to calculate
(or require the Mortgagor to provide such calculation to the Master Servicer or the Special Servicer, as applicable) the loan-to-value
ratio of the remaining Mortgaged Property or Mortgaged Properties or the fair market value of the real property constituting the
remaining Mortgaged Property or Mortgaged Properties, for purposes of REMIC qualification of the related Serviced Mortgage Loan,
then, unless then permitted by the REMIC Provisions, such calculation shall exclude the value of personal property and going concern
value, if any. In connection with approving any such release or taking, the Master Servicer or Special Servicer, as applicable,
shall calculate the loan-to-value ratio in a manner consistent with the prior sentence, and if such calculation is greater than
125%, the Master Servicer or Special Servicer, as applicable, will require a payment of principal in an amount equal to or greater
than a “qualified amount” as determined under Revenue Procedure 2010-30 or successor provisions unless the related


 






    	-275- 



     


    

 


Mortgagor provides an Opinion of Counsel that if such amount is not paid the related Mortgage Loan will not fail to be a Qualified
Mortgage.


 


(i)          If
and to the extent that the Trust, as holder of an Outside Serviced Mortgage Loan, is entitled to exercise any consent and/or consultation
rights with respect to modifications, waivers and amendments or certain other major decisions under the applicable Outside Servicing
Agreement, (a) any such consent rights shall be exercised by the Controlling Class Representative (unless a Control Termination
Event exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan) or by the Master Servicer (if a Control Termination
Event exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan), in each case in accordance with Section 3.01(i),
and (b) any such consultation rights shall be exercised by the Controlling Class Representative (unless a Consultation Termination
Event exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan) or by the Master Servicer (if a Consultation
Termination Event exists or such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan), in each case in accordance with
Section 3.01(i); provided that, after the occurrence and during the continuance of an Operating Advisor Consultation
Trigger Event, any such consultation rights shall be exercised by the Master Servicer or the Controlling Class Representative,
as applicable, jointly with the Operating Advisor (but, in the case of the Operating Advisor, only with respect to matters similar
to Major Decisions). The Special Servicer shall only be obligated to forward any requests received from the related Outside Servicer
or the related Outside Special Servicer, as applicable, for such consent and/or consultation to the Master Servicer (who shall
forward any such request to the Controlling Class Representative except if a Control Termination Event or Consultation Termination
Event, as applicable, has occurred and is continuing or if such Outside Serviced Mortgage Loan is an Excluded Mortgage Loan and,
following the occurrence and during the continuance of an Operating Advisor Consultation Trigger Event, to the Operating Advisor),
and the Special Servicer shall have no right or obligation to exercise any such consent or consultation rights.


 


Section 3.25          Additional
Obligations With Respect to Certain Mortgage Loans.


 


(a)          With
respect to each Mortgage Loan (other than an Outside Serviced Mortgage Loan) with a Stated Principal Balance in excess of $35,000,000,
in connection with any replacement of the Manager for the related Mortgaged Property, the Master Servicer or Special Servicer,
as applicable, to the extent permitted by the related Loan Documents, shall require a Rating Agency Confirmation and shall condition
its consent to such replacement on the Mortgagor paying for such Rating Agency Confirmation.


 


(b)          With
respect to any Mortgage Loan (other than an Outside Serviced Mortgage Loan), if any mezzanine loan is directly or indirectly secured
by any equity interest of the related Mortgagor, the Master Servicer (if (i) the related Mortgage Loan is a Performing Serviced
Loan and (ii) the performance of the particular obligation would not constitute a Special Servicer Decision or a Major Decision)
or the Special Servicer (if (i) the related Mortgage Loan is a Specially Serviced Loan or (ii) the performance of the particular
obligation would constitute a Special Servicer Decision or a Major Decision) shall perform the obligations of the Trust, as holder
of the related Mortgage Loan, or its servicer or agent under the related mezzanine loan intercreditor agreement.

Section         3.26 Certain
Matters Relating to the Outside Serviced Mortgage Loans.


 


(a)          With
respect to each Outside Serviced Mortgage Loan, in the event that any of the related Outside Trustee, the related Outside Servicer
or the related Outside Special Servicer shall be replaced in accordance with the terms of the applicable Outside Servicing Agreement,
the Master Servicer and the Special Servicer shall acknowledge its successor as the successor to the related Outside Trustee, the
related Outside Servicer or the related Outside Special Servicer, as the case may be, in each case with reasonable promptness following
request therefor by a party to the applicable Outside Servicing Agreement. In addition to the foregoing, with respect to each Servicing
Shift Loan Combination, after the related Servicing Shift Date the related Mortgage Loan shall be an Outside Serviced Mortgage
Loan, and the rights, duties and obligations of the Trust and the parties to this Agreement shall be as set forth herein with respect
to Outside Serviced Mortgage Loans.


 


(b)          With
respect to each Servicing Shift Loan Combination, prior to the related Servicing Shift Date, the Custodian shall hold the Mortgage
File with respect to such Servicing Shift Loan Combination. Following the related Servicing Shift Date and upon the transfer of
servicing of the related Servicing Shift Mortgage Loan to the related Outside Servicing Agreement in accordance with the related
Co-Lender Agreement, (i) the Certificate Administrator shall transfer (or cause any Custodian appointed by it to transfer) the
Mortgage File (other than the Note(s) evidencing the related Servicing Shift Mortgage Loan and corresponding allonges, the originals
of which shall be retained by the Custodian) for such Servicing Shift Loan Combination to the related Outside Trustee (provided
that the Custodian shall retain a photocopy of the Mortgage File) in accordance with the provisions and conditions set forth in
clause (B) of the second paragraph of Section 2.01(c) and (ii) the Master Servicer shall, upon written request, if the Master
Servicer is not the related Outside Servicer, transfer the Servicing File along with any escrows or reserve funds held for such
Servicing Shift Loan Combination to the related Outside Servicer.


 


Section          3.27 Additional
Matters Regarding Advance Reimbursement.


 


(a)          Upon
the determination that a previously made Advance is a Nonrecoverable Advance, to the extent that the reimbursement thereof would
exceed the full amount of the principal portion of general collections on the Mortgage Loans deposited in the Collection Account,
the Master Servicer, the Special Servicer or the Trustee, at its own option and in its sole discretion, as applicable, instead
of obtaining reimbursement for the remaining amount of such Nonrecoverable Advance pursuant to Section 3.06(a)(ii)(B)
of this Agreement immediately, may elect to defer reimbursement for some or all such portion of the Nonrecoverable Advance during
the one-month Collection Period ending on the then-current Determination Date, for successive one-month periods for a total not
to exceed 12 months; provided that any deferral in excess of 6 months shall be subject to the consent of the Controlling
Class Representative (or, in the case of a Property Advance with respect to a Serviced Outside Controlled Loan Combination, the
related Outside Controlling Note Holder) (unless, if the Controlling Class Representative is the consenting party, a Control Termination
Event has occurred and is continuing, in which case the Controlling Class Representative must be consulted with unless a Consultation
Termination Event has occurred and is continuing). If the Master Servicer, the Special Servicer or the Trustee makes such an election
in its sole discretion to defer reimbursement


 






    	-277- 



     


    

 


with
respect to all or a portion of a Nonrecoverable Advance (together with interest thereon), then such Nonrecoverable Advance (together
with interest thereon) or portion thereof shall continue to be fully reimbursable in the subsequent Collection Period (subject,
again, to the same sole discretion option to defer; it is acknowledged that, in such a subsequent period, such Nonrecoverable
Advance shall again be reimbursable pursuant to Section 3.06(a)(ii)(B) of this Agreement). In connection with a potential
election by the Master Servicer, the Special Servicer or the Trustee to defer reimbursement of a particular Nonrecoverable Advance
or portion thereof during the one-month Collection Period ending on the related Determination Date for any Distribution Date,
the Master Servicer, the Special Servicer or the Trustee shall further be authorized to wait for principal collections to be received
before making its determination of whether to defer reimbursement of a particular Nonrecoverable Advance or portion thereof) until
the end of such Collection Period; provided, however, if, at any time the Master Servicer, the Special Servicer
or the Trustee, as applicable, determines that the reimbursement of a Nonrecoverable Advance during any Collection Period will
exceed the full amount of the principal portion of general collections deposited in the Collection Account for the related Distribution
Date, then the Master Servicer, the Special Servicer or the Trustee, as applicable, shall, through a posting to the Rule 17g-5
Information Provider’s Website pursuant to Section 12.13 of this Agreement, give the Rating Agencies at least
15 days’ notice prior to any reimbursement to it of Nonrecoverable Advances from amounts in the Collection Account allocable
to interest on the Mortgage Loans unless (1) the Master Servicer, the Special Servicer or the Trustee, as applicable, determines
in its sole discretion that waiting 15 days after such a notice could jeopardize the Master Servicer’s, the Special Servicer’s
or the Trustee’s, as applicable, ability to recover such Nonrecoverable Advances, (2) changed circumstances or new
or different information becomes known to the Master Servicer, the Special Servicer or the Trustee, as applicable, that could
affect or cause a determination of whether any Advance is a Nonrecoverable Advance, whether to defer reimbursement of a Nonrecoverable
Advance or the determination in clause (1) above, or (3) the Master Servicer or the Special Servicer, as applicable,
has not timely received from the Trustee information requested by the Master Servicer or the Special Servicer, as applicable,
to consider in determining whether to defer reimbursement of a Nonrecoverable Advance; provided that, if clause (1),
(2) or (3) apply, the Master Servicer, the Special Servicer or the Trustee, as applicable, shall, through a posting
to the Rule 17g-5 Information Provider’s Website pursuant to Section 12.13 of this Agreement, give Rating Agencies
notice of an anticipated reimbursement to it of Nonrecoverable Advances from amounts in the Collection Account allocable to interest
on the Mortgage Loans as soon as reasonably practicable in such circumstances. Subject to Section 12.13 of this Agreement,
the Master Servicer, the Special Servicer or the Trustee, as applicable, shall have no liability for any loss, liability or expense
resulting from any notice provided to Rating Agencies contemplated by the immediately preceding sentence. Any election by the
Master Servicer, the Special Servicer or the Trustee to defer reimbursing itself for any Nonrecoverable Advance (together with
interest thereon) or portion thereof with respect to any Collection Period shall not be construed to impose on the other
such parties any obligation to make such an election (or any entitlement in favor of any Certificateholder or any other Person
to such an election) with respect to any subsequent Collection Period or to constitute a waiver or limitation on the
right of the Master Servicer, the Special Servicer or the Trustee to otherwise be reimbursed for such Nonrecoverable Advance immediately
(together with interest thereon). Any such election by the Master Servicer, the Special Servicer or the Trustee shall not be construed
to impose any duty on any other such party to make such an election (or any entitlement in favor of any Certificateholder or any
other Person to such an election). Any such election by any such party to


 






    	-278- 



     


    

 


defer reimbursing itself or obtaining reimbursement
for any Nonrecoverable Advance or portion thereof with respect to any one or more Collection Periods shall not limit the accrual
of interest on such Nonrecoverable Advance for the period prior to the actual reimbursement of such Nonrecoverable Advance. None
of the Master Servicer, the Special Servicer, the Trustee or the other parties to this Agreement will have any liability to one
another or to any of the Certificateholders for any such election that such party makes to defer or not to defer reimbursing itself
as contemplated by this paragraph or for any losses, damages or other adverse economic or other effects that may arise from such
an election nor will such election constitute a violation of the Servicing Standard or any duty under this Agreement. The Master
Servicer’s, the Special Servicer’s or the Trustee’s, as applicable, election, if any, to defer reimbursement
of such Nonrecoverable Advances as set forth above is an accommodation to the Certificateholders and shall not be construed as
an obligation on the part of the Master Servicer, the Special Servicer or the Trustee, as applicable, or a right of the Certificateholders.
Nothing herein shall give the Master Servicer, the Special Servicer or the Trustee the right to defer reimbursement of a Nonrecoverable
Advance if there are principal collections then available in the Collection Account pursuant to Section 3.06 of this
Agreement or to defer reimbursement of a Nonrecoverable Advance for an aggregate period exceeding 12 months.


 


(b)          If
the Master Servicer is required to make a Property Advance, but does not do so within 15 days after the Property Advance is required
to be made, then the Trustee will be required: (i) if a Responsible Officer of the Trustee has actual knowledge of the failure,
to give the Master Servicer notice of its failure; and (ii) if the failure continues for three more Business Days, to make
the Advance unless the Trustee determines such advance to be a Nonrecoverable Advance.


 


Section 3.28          Serviced
Companion Loan Intercreditor Matters.


 


(a)          If,
pursuant to Section 2.03, Section 3.17 or Section 9.01 of this Agreement, any Mortgage Loan
that relates to a Serviced Loan Combination is purchased from, repurchased from or substituted out of, the Trust Fund, the subsequent
holder thereof shall be bound by the terms of the related Co-Lender Agreement and shall assume the rights and obligations of the
holder of the Note that represents the related Mortgage Loan under such Co-Lender Agreement. All portions of the related Mortgage
File and (to the extent provided under the related Mortgage Loan Purchase Agreement) other documents pertaining to such Mortgage
Loan shall be endorsed or assigned to the extent necessary or appropriate to the purchaser of such Mortgage Loan in its capacity
as the holder of the Note that represents the related Mortgage Loan (as a result of such purchase, repurchase or substitution)
and (except for the actual Note) on behalf of the holder of the Note(s) that represents the Serviced Companion Loan(s). Thereafter,
such Mortgage File shall be held by the holder of the Note that represents the related Mortgage Loan or a custodian appointed thereby
for the benefit thereof, on behalf of itself and the holder of the related Serviced Companion Loan(s) as their interests appear
under the related 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 Serviced
Loan Combinations.


 


(b)          With
respect to each Serviced Companion Loan, notwithstanding any rights the Operating Advisor or the Controlling Class Representative
hereunder may have to consult with


 






    	-279- 



     


    

 


respect
to any action or other matter with respect to the servicing of such Serviced Companion Loan, to the extent the related Co-Lender
Agreement provides that such right is exercisable by the related Serviced Companion Loan Holder or its Companion Loan Holder Representative
or is exercisable in conjunction with any related Serviced Companion Loan Holder, then (i) neither the Operating Advisor
nor the Controlling Class Representative shall be permitted to exercise such right or (ii) to the extent provided in the
related Co-Lender Agreement, the Operating Advisor or the Controlling Class Representative, as applicable, shall be required to
exercise such right in conjunction with any related Serviced Companion Loan Holder or its Companion Loan Holder Representative,
as applicable. Additionally, notwithstanding anything in this Agreement to the contrary, the Master Servicer or Special Servicer,
as applicable, shall consult with, seek the approval of, or obtain the consent of the holder of any Serviced Companion Loan or
its Companion Loan Holder Representative with respect to any matters with respect to the servicing of such Serviced Companion
Loan to the extent required under related Co-Lender Agreement and shall not take such actions requiring consent of or consultation
with the Serviced Companion Loan Holder or its Companion Loan Holder Representative without such consent or consultation. In addition,
notwithstanding anything to the contrary, the Master Servicer or Special Servicer, as applicable, shall deliver reports and notices
to the Serviced Companion Loan Holder or its Companion Loan Holder Representative (or the master servicer or special servicer
for the related Other Securitization Trust on behalf of the Serviced Companion Loan Holder) as required under the Co-Lender Agreement.


 


(c)          With
respect to each Serviced Loan Combination, the Master Servicer shall prepare, or cause to be prepared, on an ongoing basis a statement
setting forth, to the extent applicable to such Serviced Loan Combination:


 


(i)      
    (A) the amount of the distribution from the related Loan Combination Custodial Account allocable to
principal and (B) separately identifying the amount of scheduled principal payments, balloon payments, principal prepayments
made at the option of the Mortgagor 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 related Serviced Loan
Combination;


 


(ii)          the
amount of the distribution from the related Loan Combination Custodial Account allocable to interest and the amount of Default
Interest allocable to the related Serviced Loan Combination;


 


(iii)         the
amount of the distribution to the related Serviced Companion Loan Holder, separately identifying the non-default interest, principal
and other amounts included therein, and if the distribution to a Serviced Companion Loan Holder is less than the full amount that
would be distributable to such Serviced Companion Loan Holder 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
related Serviced Loan Combination;


 


(iv)         the
principal balance of each of the related Serviced Loan Combination and related Serviced Companion Loan after giving effect to the
distribution of principal on the most recent Distribution Date; and


 



    	-280- 



     


    




 


(v)          the
amount of the servicing fees paid to the Master Servicer and the Special Servicer with respect to the most recent Distribution
Date, showing separately the Servicing Fee, the Special Servicing Fee, the Workout Fee and the Liquidation Fee.


 


Not later than each Distribution
Date, the Master Servicer shall make the foregoing statement available to the Serviced Companion Loan Holder (or the master servicer
or special servicer for the related Other Securitization Trust on its behalf) by electronic means (which may include posting such
information pursuant to the applicable CREFC® reports on the Master Servicer’s website) and by such other means of delivery
as required under the related Co-Lender Agreement.


 


(d)          If
any Serviced Companion Loan becomes the subject of an Other PSA Asset Review pursuant to the related Other Pooling and Servicing
Agreement, the Master Servicer, the Special Servicer, the Trustee and the Certificate Administrator shall reasonably cooperate
(and the Certificate Administrator shall cause any Custodian appointed by it to reasonably cooperate) with the related Other Asset
Representations Reviewer in connection with such Other PSA Asset Review by providing the related Other Asset Representations Reviewer
with any documents reasonably requested by the related Other Asset Representations Reviewer, but only to the extent that (i) the
Other Asset Representations Reviewer has not been able to obtain such documents from the related Mortgage Loan Seller and (ii)
such documents are in the possession of the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator or
any Custodian appointed by the Certificate Administrator, as the case may be. For the avoidance of doubt, none of the Master Servicer,
the Special Servicer, the Trustee, the Certificate Administrator or the Custodian shall have other obligations with respect to
any such Other PSA Asset Review nor shall any such party be bound by the results of any such asset review.


 


(e)          With
respect to any Other Pooling and Servicing Agreement that satisfies Regulation RR in whole or in part through the purchase by a
third party purchaser of an eligible horizontal residual interest pursuant to Rule 7 of Regulation RR (a “Regulation RR
Other PSA”), at any time that the Special Servicer has received written notice of such Regulation RR Other PSA and that

Annual Report shall set forth
the Operating Advisor’s assessment of the Special Servicer’s performance of its duties under this Agreement during
the prior calendar year. Subject to the restrictions in this Agreement, including, without limitation, Section 3.29(b) of
this Agreement, each such Operating Advisor Annual Report shall (A) state whether the Operating Advisor believes, in its sole
discretion exercised in good faith, that the Special Servicer is performing its duties in compliance with (1) the Servicing Standard
and (2) the Special Servicer’s obligations under this Agreement, and (B) identify any material deviations with respect to
such matters from (i) the Servicing Standard or (ii) the Special Servicer’s obligations under this Agreement, and (C) comply

Information limits the Operating Advisor from performing its duties under this Agreement, the Operating Advisor shall not be subject
to any liability arising from its lack of access to Privileged Information. Such Operating Advisor Annual Report shall be delivered
to the Trustee, the Certificate Administrator, the Rule 17g-5 Information Provider and the Depositor, and the Certificate Administrator
and the Rule 17g-5 Information Provider shall promptly, upon receipt, post such Operating Advisor Annual Report on the Certificate
Administrator’s Website and the Rule 17g-5 Information Provider’s Website, respectively; provided, however,
that the Operating Advisor shall deliver to the Special Servicer, the Controlling Class Representative (if a Serviced Loan other
than a Serviced Outside Controlled Loan Combination is addressed and a Consultation Termination Event does not exist) and the related
Outside Controlling Note Holder (if a Serviced Outside Controlled Loan Combination is addressed), any annual report produced by
the Operating Advisor at least ten (10) calendar days prior to its delivery to the Depositor, the Trustee and the Certificate Administrator.
The Operating Advisor may, but shall not be obligated to, revise the Operating Advisor Annual Report based on any comments received
from the Special Servicer or the Controlling Class Representative. In the event the Special Servicer is replaced during the prior
calendar year, the Operating Advisor shall only be required to prepare an Operating Advisor Annual Report relating to each entity
that was acting as Special Servicer as of December 31 of the prior calendar year and is continuing in such capacity through the
date of such Operating Advisor Annual Report. In connection with the Operating Advisor Annual Report and the reviews provided for
in Sections 3.29(b) and 3.29(d)(i), the Operating Advisor shall perform its review on the basis of the
Special Servicer’s performance of its duties with respect to Specially Serviced Loans and, after the occurrence and during
the continuance of an Operating Advisor Consultation Trigger Event, with respect to Major Decisions on Performing Serviced Loans,
as well as the extent to which those duties were performed in accordance with the Servicing Standard, with reasonable consideration
by the Operating Advisor of any annual compliance statement, any assessment of compliance and any attestation report delivered
to the Operating Advisor pursuant to Section 10.08, Section 10.09 and Section 10.10 of this Agreement,
as applicable, or made available to the Operating Advisor on the Certificate Administrator’s Website, any Asset Status Report,
any Major Decision Reporting Package and other information (other than any communications between the related Directing Holder
or any Serviced Companion Loan Holder (or its Companion Loan Holder Representative), as applicable, and the Special Servicer that
would be Privileged Information) that the


 






    	-284- 



     


    

 


Operating Advisor is required to review on the Certificate Administrator’s website
or that is prepared by the Special Servicer and delivered or made available to the Operating Advisor pursuant to this Agreement.


 


(e)          After
the calculation but prior to the utilization by the Special Servicer of any of the calculations with respect to an applicable Specially
Serviced Loan related to (i) Appraisal Reduction Amounts, (ii) Collateral Deficiency Amounts or (iii) net present value
used in the Special Servicer’s determination of the course of action to be taken in connection with the workout or liquidation
of such Specially Serviced Loan, the Special Servicer shall forward such calculations, together with any supporting material or
additional information necessary in support thereof (including such additional information reasonably requested by the Operating
Advisor to confirm the mathematical accuracy of such calculations, but not including any Privileged Information), to the Operating
Advisor promptly, but in any event no later than two (2) Business Days after preparing such calculations, and the Operating Advisor
shall promptly, but no later than three (3) Business Days after receipt of such calculations and any supporting or additional materials,
recalculate and verify the accuracy of the mathematical calculations and the corresponding application of the non-discretionary
portion of the applicable formulas required to be utilized in connection with any such calculation.


 


In connection with this
Section 3.29, in the event the Operating Advisor does not agree with the mathematical calculations or the application of
the non-discretionary portions of the applicable formulas required to be utilized for such calculation, the Operating Advisor and
the Special Servicer shall consult with each other in order to resolve any inaccuracy in the mathematical calculations or the application
of the non-discretionary portions of the applicable formulas in arriving at those mathematical calculations or any disagreement
within five (5) Business Days of delivery of such calculations to the Operating Advisor. In the event the Operating Advisor and
Special Servicer are not able to resolve such inaccuracies or disagreement prior to the end of such five (5) Business Day period,
the Operating Advisor shall promptly notify the Certificate Administrator of such disagreement and the Certificate Administrator
shall determine which calculation is to apply. In making such determination, the Certificate Administrator may hire an independent
third-party to assist with any such calculation at the expense of the Trust Fund.


 


(f)          After
the occurrence and during the continuance of an Operating Advisor Consultation Trigger Event, the Operating Advisor shall consult
(on a non-binding basis) with the Special Servicer in connection with (i) any Major Decision with respect to a Serviced Loan in
accordance with Section 3.24, Section 6.09 and this Section 3.29 and (ii) each Asset Status Report in accordance
with Section 3.21, and, in each case, the Special Servicer shall consider any alternative courses of action and any other
feedback provided by the Operating Advisor.


 


(g)          Subject
to the requirements of confidentiality imposed on the Operating Advisor herein (including without limitation in respect of Privileged
Information), the Operating Advisor shall respond to Inquiries relating to the Operating Advisor Annual Reports or actions by the
Master Servicer or the Special Servicer as to which the Operating Advisor has consultation rights, whether or not referenced in
any Operating Advisor Annual Report and made by Privileged Persons from time to time in accordance with the terms of Section 4.02(a)
of this Agreement.

(h)          Subject
to the Privileged Information Exception, the Operating Advisor will be obligated to keep confidential any Privileged Information
received from the Special Servicer, the related Directing Holder or any related Serviced Companion Loan Holder (or its Companion
Loan Holder Representative) in connection with the exercise of the rights of the related Directing Holder or such related Serviced
Companion Loan Holder under this Agreement (including, without limitation, in connection with the review and/or approval of any
Asset Status Report), subject to any law, rule, regulation, order, judgment or decree requiring the disclosure of such Privileged
Information.


 


(i)          The
Operating Advisor shall keep Privileged Information confidential and shall not disclose such Privileged Information to any Person
(including Certificateholders other than the Controlling Class Representative), other than (1) to the extent expressly required
by this Agreement, to the other parties to this Agreement with a notice indicating that such information is Privileged Information
or (2) pursuant to a Privileged Information Exception. Notwithstanding the foregoing, the Operating Advisor, solely to the extent
required in connection with its duties under this Agreement, will be permitted to share Privileged Information with its Affiliates
and any subcontractors of the Operating Advisor provided such Affiliates and subcontractors of the Operating Advisor agree in writing
prior to their receipt of such Privileged Information to be bound by the same confidentiality provisions applicable to the Operating
Advisor described in this Agreement and a copy of such agreement is provided to the parties hereto. Each party to this Agreement
that receives Privileged Information from the Operating Advisor with a notice stating that such information is Privileged Information
shall not disclose such Privileged Information to any Person without the prior written consent of the Special Servicer and, as
applicable, any related Outside Controlling Note Holder (if a Serviced Outside Controlled Loan Combination is involved) and/or,
unless a Consultation Termination Event has occurred and is continuing, the Controlling Class Representative other than pursuant
to a Privileged Information Exception.


 


(j)          On
each Master Servicer Remittance Date, the Operating Advisor shall be paid the applicable Operating Advisor Fee from amounts on
deposit in the Collection Account, pursuant to Section 3.06 of this Agreement. In addition, the Operating Advisor Consulting
Fee shall be payable to the Operating Advisor (but only to the extent such fee is actually received from the related Mortgagor
as a separately identifiable fee) with respect to each Major Decision for which the Operating Advisor has consultation rights.
Each of the Operating Advisor Fee and the Operating Advisor Consulting Fee shall be payable from funds on deposit in the Collection
Account as provided in Section 3.06 of this Agreement, but with respect to the Operating Advisor Consulting Fee only
to the extent such Operating Advisor Consulting Fee is actually received from the related Mortgagor. If the Operating Advisor has
consultation rights with respect to a Major Decision under this Agreement, the Master Servicer or the Special Servicer, as applicable,
shall use commercially reasonable efforts consistent with the Servicing Standard to collect the applicable Operating Advisor Consulting
Fee from the related Mortgagor in connection with such Major Decision, but only to the extent not prohibited by the related Loan
Documents, and shall deposit any Operating Advisor Consulting Fee so collected from the related Mortgagor into the Collection Account.
The Master Servicer or Special Servicer, as applicable, may waive or reduce the amount of any Operating Advisor Consulting Fee
payable by the related Mortgagor if it determines that such full or partial waiver is in accordance with the Servicing Standard,
but in no event shall the Master Servicer or the Special Servicer take any enforcement action with respect to the collection of
such Operating Advisor Consulting Fee other than requests for collection;


 






    	-286- 



     


    

 


provided
that the Master Servicer or the Special Servicer, as applicable, shall consult (on a non-binding basis) with the Operating
Advisor prior to any such waiver or reduction.


 


(k)          In
no event shall the Operating Advisor have the power to compel any transaction party to take or refrain from taking any action.

(a)          Notwithstanding
the terms of any related Loan Documents or other provisions of this Agreement, if any action under any Loan Documents or this Agreement
requires Rating Agency Confirmation as a condition precedent to such action, if the party (the “Requesting Party”)
required to obtain such Rating Agency Confirmation from each Rating Agency has made a request to any Rating Agency for such Rating
Agency Confirmation and if, within 10 Business Days of the Rating Agency Confirmation request being posted to the Rule 17g-5 Information
Provider’s Website, any Rating Agency has not granted such request, rejected such request or provided a Rating Agency Declination,
then (i) such Requesting Party shall promptly request the related Rating Agency Confirmation again, and (ii) if there
is no response to such second Rating Agency Confirmation request from the applicable Rating Agency within five (5) Business Days
of such second request, whether in the form of granting or rejecting such Rating Agency Confirmation request or providing a Rating
Agency Declination, then: (x) with respect to any condition in any Loan Document or related intercreditor agreement or Co-Lender
Agreement requiring a Rating Agency Confirmation or any other matter under this Agreement relating to the servicing of the Mortgage
Loans (other than as set forth in clause (y) or (z) below), the Requesting Party (or, if the Requesting Party is the related
Mortgagor, then the Master Servicer (with respect to Performing Serviced Loans if the subject action is not a Major Decision or
a Special Servicer Decision or the Master Servicer is processing a Major Decision or a Special Servicer Decision) or the Special
Servicer (with respect to Specially Serviced Loans and REO Properties and with respect to Performing Serviced Loans if the subject
action is a Major Decision or a Special Servicer Decision processed by the Special Servicer), as applicable) shall determine (with
the consent of the related Directing Holder, unless, in the case of the Controlling Class Representative, a Control Termination
Event has occurred and is continuing (but in each case only in the case of actions that would otherwise be Major Decisions), which
consent shall be pursued by the Special Servicer and deemed given if the related Directing Holder does not respond within seven (7)
Business Days of receipt of a request from the Special Servicer to consent to the Requesting Party’s determination), in accordance
with its duties under this Agreement and in accordance with the Servicing Standard, except as provided in Section 3.30(b),
whether or not such action would be in accordance with the Servicing Standard, and if the Requesting Party (or, if the Requesting
Party is the related Mortgagor, then the Master Servicer or the Special Servicer, as applicable) makes such determination, then
the requirement to obtain a Rating Agency Confirmation shall not apply; (y) with respect to a replacement of the Master Servicer
or the Special Servicer, such condition shall be considered satisfied if: (1) in the case that Moody’s is the non-responding
Rating Agency, (a) the applicable replacement master servicer or special servicer, as applicable, has confirmed in writing that
it was appointed to act, and as of the date of determination is acting, as the master servicer or special servicer, as applicable,
on a transaction level basis with respect to a CMBS transaction as to which Moody’s rated one or more classes of securities
and one or more of such classes of securities are still outstanding and rated by Moody’s and (b) Moody’s has not cited
servicing concerns of the applicable replacement master servicer or special servicer, as applicable,

the sole or material factor in any qualification, downgrade or withdrawal of the ratings (or placement on “watch status”
in contemplation of a ratings downgrade or withdrawal) of securities in any other CMBS transaction serviced by the applicable
servicer prior to the time of determination; (2) the applicable replacement master servicer has a master servicer rating
of at least “CMS3” from Fitch or the applicable replacement special servicer has a special servicer rating of at least
“CSS3” from Fitch, if Fitch is the non-responding Rating Agency; and (3) KBRA has not cited servicing concerns of
the applicable replacement master servicer or special servicer as the sole or material factor in any qualification, downgrade
or withdrawal of the ratings (or placement on “watch status” in contemplation of a ratings downgrade or withdrawal)
of securities in any other CMBS transaction serviced by the applicable servicer prior to the time of determination, if KBRA is
the non-responding Rating Agency, as applicable; and (z) with respect to a replacement or successor of the Operating Advisor,
such condition shall be deemed to be waived with respect to any non-responding Rating Agency so long as such Rating Agency has
not cited concerns regarding the replacement operating advisor as the sole or material factor in any qualification, downgrade
or withdrawal of the ratings (or placement on “watch status” in contemplation of a ratings downgrade or withdrawal)
of securities in any other CMBS transaction with respect to which the replacement operating advisor acts as trust advisor or operating
advisor prior to the time of determination.


 


Any Rating Agency Confirmation

pursuant to this Agreement, shall be made in writing, which writing shall contain a cover page indicating the nature of the Rating
Agency Confirmation request, and shall contain all back-up material reasonably necessary for the Rating Agency to process such
request, subject to Section 12.13. Such written Rating Agency Confirmation request shall be provided in electronic

Advisor or Trustee, as applicable, shall be required to send the Rating Agency Confirmation request to the Rating Agencies in accordance
with Section 12.13(b).


 


Promptly following the
Requesting Party’s (or, if the Requesting Party is the related Mortgagor, then the Master Servicer’s or the Special
Servicer’s, as applicable) determination to take any action discussed in this Section 3.30(a) without receiving
any required Rating Agency Confirmation, such Requesting Party (or the Master Servicer or the Special Servicer, as applicable)

(b)          For
the purposes of clause (ii) of Section 3.30(a), and notwithstanding anything to the contrary in Section 3.30(a),
with respect to the provisions of any Loan Document relating to defeasance (including without limitation the type of collateral
acceptable for use as defeasance collateral), release or substitution of any collateral, any applicable Rating Agency Confirmation
requirement in the Loan Documents shall not apply, even without the determination pursuant to Section 3.30(a)(ii)(x)
by the Requesting Party (or, if the Requesting Party is the related Mortgagor, by the Master Servicer (with respect to Performing
Serviced Loans if the subject action is not a Major Decision or a Special Servicer Decision or the Master Servicer is processing
a Major Decision or a Special Servicer Decision) or the Special Servicer (with respect to Specially Serviced

all other matters or actions (i) not specifically discussed in clause (ii) (x), (ii) (y) or (ii) (z) of Section 3.30(a)
above and (ii) that are not the subject of a Rating Agency Declination, the proposed action shall not be permitted to proceed
unless the applicable Requesting Party shall deliver Rating Agency Confirmation from each Rating Agency.


 


(d)          With
respect to any Serviced Companion Loan as to which there exists Serviced Companion Loan Securities, if any action relating to the
servicing and administration of any or all of the related Serviced Loans or any related REO Property (including, but not limited
to, the replacement of the Master Servicer, the Special Servicer or a sub-servicer) (the “Relevant Action”)
requires delivery of a Rating Agency Confirmation as a condition precedent to such action pursuant to this Agreement, then, except
as set forth below in this paragraph, such action will also require delivery of a Companion Loan Rating Agency Confirmation as
a condition precedent to such action from each Companion Loan Rating Agency. Each Companion Loan Rating Agency Confirmation shall
be sought by the Master Servicer or Special Servicer, as applicable, depending on whichever such party is seeking the corresponding
Rating Agency Confirmation(s) in connection with the Relevant Action. The requirement to obtain a Companion Loan Rating Agency
Confirmation with respect to any Serviced Companion Loan Securities will be subject to, will be permitted to be waived by the Master

Section 3.33          Litigation
Control.


 


(a)          The
Special Servicer (with respect to each Mortgage Loan and Serviced Loan Combination other than any Excluded Special Servicer Mortgage
Loan) shall in accordance with the Servicing Standard, direct, manage, prosecute and/or defend any action brought by a Mortgagor,
guarantor, other obligor on the related Note or any affiliates thereof (each a “Borrower-Related Party”) against
the Trust (including, without limitation, any action in which both the Trust and the Master Servicer are named) and/or the Special
Servicer, and represent the interests of the Trust in any litigation relating to a Mortgage Loan or Loan Combination, as applicable,
the related Mortgaged Property or other collateral securing such Mortgage Loan or Loan Combination, or the enforcement of the obligations
of a Borrower-Related Party under the related Loan Documents (“Loan-Related Litigation”). In the event that
the Master Servicer is named in any Loan-Related Litigation but the Special Servicer is not named in such Loan-Related Litigation
(and regardless of whether the Trust is named), the Master Servicer shall notify the Special Servicer of such litigation as soon
as practicable but in any event no later than within ten (10) Business Days of the Master Servicer receiving service of such Loan-Related
Litigation.


 


(b)          To
the extent the Master Servicer is named in Loan-Related Litigation, and neither the Trust nor the Special Servicer is named, in
order to effectuate the role of such Special Servicer as contemplated by the immediately preceding paragraph, the Master Servicer
shall (i) provide quarterly status reports to the Special Servicer, regarding such Loan-Related Litigation; (ii) use reasonable
efforts to have the Trust replace the Master Servicer as the appropriate party to the lawsuit; and (iii) so long as the Master
Servicer remains a party to the lawsuit, consult with and act at the direction of the Special Servicer with respect to material
decisions and material monetary settlements related to the interests of the Trust in such Loan-Related Litigation, including but
not limited to the selection of counsel. If and/or once the Trust and/or the Special Servicer are named, the Special Servicer shall
assume control of the Loan-Related Litigation as provided in Section 3.33(a) above, the Master Servicer shall no longer
have the reporting obligation set forth above and the Special Servicer’s selection of counsel shall be subject to the consent
of the Master Servicer which consent shall not be unreasonably withheld, delayed or conditioned. Further, if there are claims against
the Master Servicer, the Trust and the Special Servicer, each party at the request of the other, shall enter into a joint defense
agreement in accordance with Section 3.33(h) below.


 


(c)          The
Special Servicer shall not (i) undertake (or direct the Master Servicer to undertake) any material settlement of any Loan-Related
Litigation or (ii) initiate any material Loan-Related Litigation unless and until it has notified in writing the Controlling Class
Representative (only if the related Mortgage Loan is not an Excluded Mortgage Loan and for so long as no Consultation Termination
Event has occurred and is continuing and to the extent the identity of the Controlling Class Representative is actually known to
the Special Servicer; provided that the Special Servicer shall make due inquiry of the Certificate Administrator as to the identity
of the Controlling Class Representative), and the related holder of any Companion Loan (if such matter affects a Companion Loan
and to the extent the identity of the holder of such Companion Loan is actually known to the Special Servicer), and the Controlling
Class Representative (only if the related Mortgage Loan is not an Excluded Mortgage Loan and for so long as no Control


 






    	-291- 



     


    

 


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


 


(d)          Notwithstanding
anything to the contrary in this Section 3.33, neither of the Special Servicer nor the Master Servicer shall follow any
advice, direction or consultation provided by the Controlling Class Representative that would require or cause such Special Servicer
or the Master Servicer, as applicable, to violate any applicable law, be inconsistent with the Servicing Standard, require or cause
such Special Servicer or the Master Servicer, as applicable, to violate provisions of this Agreement, require or cause such Special
Servicer or the Master Servicer, as applicable, to violate the terms of any Mortgage Loan or Loan Combination, expose any Certificateholder
or any party to this Agreement or their Affiliates, officers, directors or agents to any claim, suit or liability, cause any Trust
REMIC created hereunder to fail to qualify as a REMIC, or any Grantor Trust created hereunder to fail to qualify as a grantor trust
for federal income tax purposes or result in the imposition of a “prohibited transaction” or “prohibited contribution”
tax under the REMIC Provisions, or materially expand the scope of the Special Servicer’s, the Master Servicer’s, the
Certificate Administrator’s or the Trustee’s, as applicable, responsibilities under this Agreement.


 


(e)          Notwithstanding
the right of the Special Servicer provided in this Section to represent the interests of the Trust in Loan-Related Litigation,
the Master Servicer shall retain the right at all times to make final decisions in the Master Servicer’s reasonable discretion,
relating to claims against the Master Servicer where a settlement by the Special Servicer does not meet the conditions set forth
in subclauses (i) through (v) of the first sentence of clause (g) below, including but not limited to the right to engage separate
counsel, to make settlement decisions with respect to claims asserted against the Master Servicer and to appear in any proceeding
on its own behalf. The cost related to or incurred in connection with exercising such rights shall be subject to indemnification
as and to the extent provided in this Agreement. For the sake of clarity, the Master Servicer’s rights do not include the
right to settle any claims against the Master Servicer without the Special Servicer’s consent if such settlement would (i)
contain any admission of liability or wrongdoing on the part of the Master Servicer, the Trust, the Special Servicer or any other
party to this Agreement, (ii) provide for the payment of damages or any sums for which the Master Servicer will seek indemnification
from the Trust or any party to this Agreement or (iii) prejudice or impair the defense or counterclaims of the Trust or any party
to this Agreement with respect to such Loan-Related Litigation.


 


(f)          Further,
nothing in this Section shall require the Master Servicer, any Special Servicer or any other party to this Agreement to take or
fail to take any action which, in such party’s good faith and reasonable judgment, may result in a violation of the REMIC
Provisions or Grantor Trust Provisions, subject the Master Servicer, any Special Servicer or other


 






    	-292- 



     


    

 


such
party to liability, or materially expand the scope of the Master Servicer’s, any Special Servicer or such party’s
obligations under this Agreement.


 


(g)          Notwithstanding
the Master Servicer’s right to make determinations relating to claims against the Master Servicer, the Special Servicer may
not direct the Master Servicer to settle any claims asserted against the Master Servicer (whether or not the Trust or the Special
Servicer is named in any such claims or Loan-Related Litigation) without the consent of the Master Servicer unless (i) such settlement
or other direction does not contain or require any admission of liability, wrongdoing or consent to injunctive relief on the part
of the Master Servicer and the Master Servicer is fully released, (ii) the cost of such settlement or any resulting judgment is
and shall be paid by the Trust pursuant to the terms of this Agreement, and payment of such cost or judgment is provided for in
this Agreement, (iii) the Master Servicer is and shall be indemnified as and to the extent provided in this Agreement for all costs
and expenses of the Master Servicer incurred in defending and settling the Loan-Related Litigation and for any related judgment,
(iv) any action taken by the Master Servicer at the direction of the Special Servicer shall be deemed (as to the Master Servicer)
to be in compliance with the Servicing Standard, and (v) the Special Servicer provides the Master Servicer with assurance reasonably
satisfactory to the Master Servicer as to the items in clauses (i), (ii), (iii) and (iv). With respect to any material settlements
with respect to any Mortgage Loan other than an Excluded Mortgage Loan, the Special Servicer shall be required to obtain the consent
or consultation of the Controlling Class Representative prior to the occurrence and continuance of a Control Termination Event
or Consultation Termination Event, respectively.


 


(h)          In
the event both the Master Servicer and the Special Servicer or Trust are named in Loan-Related Litigation, the Master Servicer
and the Special Servicer shall (i) to the extent that the Master Servicer and the Special Servicer deem it appropriate, use reasonable
efforts to enter into a joint defense agreement and (ii) cooperate with each other to afford the Master Servicer and the Special
Servicer the rights afforded to such party in this Section.


 


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


 


(j)          Notwithstanding
the foregoing, and subject to the requirements of the second sentence in the second paragraph of Section 3.01(a) of this
Agreement and subject to the power of attorney, (x) in the event that any action, suit, litigation or proceeding names the Trustee,
Certificate Administrator, Custodian or Operating Advisor, in its respective individual capacity, or in the event that any judgment
is rendered against the Trustee, Certificate Administrator, Custodian or Operating Advisor, as applicable, in its individual capacity,
the Trustee, Certificate Administrator, Custodian or Operating Advisor, as applicable, upon prior written notice to the Master
Servicer or the Special Servicer, as applicable, may retain separate counsel and appear in any such proceeding on its own behalf
in order to protect and represent its interests (but not to otherwise direct, manage or prosecute such litigation or claim); (y)
in the event of any action, suit, litigation or proceeding, other than an action, suit, litigation or proceeding relating to the
enforcement of the obligations of a Mortgagor, guarantor or other obligor under the related Loan Documents, or otherwise relating
to one or more Mortgage Loans or Mortgaged Properties, neither


 






    	-293- 



     


    

 


the
Master Servicer nor the Special Servicer shall, without the prior written consent of the Trustee, Certificate Administrator, Custodian
or Operating Advisor, as applicable, (i) initiate an action, suit, litigation or proceeding in the name of the Trustee, Certificate
Administrator, Custodian or Operating Advisor, as applicable, whether in such capacity or individually, (ii) engage counsel to
represent the Trustee, Certificate Administrator, Custodian or Operating Advisor, as applicable, (iii) settle any claim giving
rise to liability to the Trustee, Certificate Administrator, Custodian or Operating Advisor, as applicable, in its individual
capacity, or (iv) prepare, execute or deliver any government filings, forms, permits, registrations or other documents or take
any other similar actions with the intent to cause, and that actually causes, the Trustee, Certificate Administrator, Custodian
or Operating Advisor, as applicable, to be registered to do business in any state (provided that neither the Master Servicer nor
the Special Servicer shall be responsible for any delay due to the unwillingness of the Trustee, Certificate Administrator, Custodian
or Operating Advisor to grant such consent); and (z) in the event that any court finds that the Trustee, Certificate Administrator,
Custodian or Operating Advisor, as applicable, is a necessary party in respect of any action, suit, litigation or proceeding relating
to or arising from this Agreement or any Mortgage Loan, the Trustee, the Certificate Administrator, the Custodian or the Operating
Advisor, as applicable, shall have the right to retain separate counsel and appear in any such proceeding on its own behalf in
order to protect and represent its interests, whether as Trustee, Certificate Administrator, Custodian or Operating Advisor, as
applicable, or individually (but not to otherwise direct, manage or prosecute such litigation or claim); provided, however, nothing
in this subsection shall be interpreted to preclude the Special Servicer (with respect to any material Loan-Related Litigation
with respect to any Mortgage Loan other than an Excluded Mortgage Loan, with the consent or consultation of the Controlling Class
Representative prior to the occurrence and continuance of a Control Termination Event or Consultation Termination Event, respectively)
from initiating any action, suit, litigation or proceeding in its own name as representative of the Trust.


 


(k)          Notwithstanding
the foregoing or anything to the contrary in this Section, this Section shall not apply to any Loan-Related Litigation and shall
have no force and effect with respect thereto, in the event that either (i) at the time such Loan-Related Litigation is commenced
or at any time during the continuance of such Loan-Related Litigation, Midland Loan Services, a Division of PNC Bank, National
Association is no longer the Special Servicer with respect to the related Mortgage Loan or related Loan Combination or has received
notice of its replacement as Special Servicer with respect to the related Mortgage Loan or related Loan Combination whether or
not such replacement is effective or (ii) the Depositor, any Sponsor, any Mortgage Loan Seller, any Initial Purchaser, any Underwriter,
or any of their respective affiliates is an adverse party (with respect to the Trust or the Special Servicer) in such Loan-Related
Litigation or holds any interest which is adverse to the Trust or the Special Servicer in the related Mortgage Loan or related
Loan Combination (or any portion thereof) or the related Mortgaged Property to which Loan-Related Litigation relates, unless otherwise
agreed to in writing by each of the Depositor, Sponsor, Mortgage Loan Seller, Initial Purchaser, Underwriter, or affiliate that
is such a party or holds such interest. For the avoidance of doubt, the rights and obligations of the Master Servicer and the Special
Servicer relating to any Loan-Related Litigation shall be limited solely to the representation of the Trust and itself, separate
and apart from the interests of any other party thereto. For the further avoidance of doubt, in such circumstance described in
this paragraph, the rights and obligations of the Master Servicer and the Special Servicer relating to litigation shall be as otherwise
set forth with respect to servicing in this Agreement.

Under Regulation RR,
any Third-Party Purchaser is prohibited from being Risk Retention Affiliated with, among other persons, the Master Servicer, the
Trustee, the Certificate Administrator, the Operating Advisor or the Asset Representations Reviewer. As long as the prohibition

Officer of the Certificate Administrator or the Trustee, as applicable, obtaining actual knowledge that the Master Servicer, the
Certificate Administrator or the Trustee, as applicable, is or has become Risk Retention Affiliated with or a Risk Retention Affiliate
of the Third Party Purchaser (in such case, an “Impermissible TPP Affiliate”), (ii) the Master Servicer, Certificate

shall promptly notify the Sponsors and the other parties to this Agreement and resign in accordance with Section 6.04, Section
8.07 or Section 11.03, as applicable. The resigning Impermissible Risk Retention Affiliate shall bear all reasonable
out-of-pocket costs and expenses of each other party to this Agreement, the Trust and each Rating Agency in connection with such
resignation as and to the extent required under this Agreement, provided however, if the affiliation causing an Impermissible
Risk Retention Affiliate is the result of the Third Party Purchaser acquiring an interest in such Impermissible Risk Retention
Affiliate or an affiliate of such Impermissible Risk Retention Affiliate, then such costs and expenses shall be an expense of the
Trust.

to the Holders of the Class H-RR Certificates, in respect of interest, up to an amount equal to the Interest Distribution
Amount of that Class;


 


(xxvi)      Twenty-Sixth,
after the Certificate Balances of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB, Class A-S, Class B, Class C,
Class D, Class E-RR, Class F-RR and Class G-RR Certificates have been reduced to zero, to the Holders of the Class H-RR Certificates,
in reduction of the related Certificate Balance, up to an amount equal to the Principal Distribution Amount for such Distribution
Date, less the portion of such Principal Distribution Amount distributed pursuant to all prior clauses, until the related Certificate
Balance is reduced to zero;


 


(xxvii)      Twenty-Seventh,
to the Holders of the Class H-RR Certificates, up to an amount equal to the aggregate of unreimbursed Realized Losses previously
allocated to such Class, plus interest thereon at the Pass-Through Rate for such Class compounded monthly from the date each related
Realized Loss was allocated to such Class;


 


(xxviii)     Twenty-Eighth,
to the Holders of the Class J-RR Certificates, in respect of interest, up to an amount equal to the Interest Distribution
Amount of that Class;


 


(xxix)       Twenty-Ninth,
after the Certificate Balances of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB, Class A-S, Class B, Class C,
Class D, Class E-RR, Class F-RR, Class G-RR and Class H-RR Certificates have been reduced to zero, to the Holders of the Class
J-RR Certificates, in reduction of the related Certificate Balance, up to an amount equal to the Principal Distribution Amount
for such Distribution Date, less the portion of such Principal Distribution Amount distributed pursuant to all prior clauses,

(xxx)        Thirtieth,

Realized Loss was allocated to such Class; and


 


(xxxi)       Last,
to the Holders of the Class R Certificates in respect of the Upper-Tier Residual Interest, in the amount of any remaining
portion of the Available Funds for such Distribution Date on deposit in the Upper-Tier REMIC Distribution Account.


 


Notwithstanding the foregoing,
on each Distribution Date occurring on and after the Cross-Over Date, in place of the allocation of principal payments described
in clause (ii) above, remaining Available Funds at such level shall be distributed up to an amount equal to the Principal
Distribution Amount for such Distribution Date to the respective Holders of Class A-1, Class A-2, Class A-3, Class A-4
and Class A-AB Certificates, pro rata, based on their respective Certificate Balances, in reduction of their respective
Certificate Balances (and the schedule for the Class A-


 






    	-300- 



     


    

 


AB
principal distributions shall be disregarded). Any remaining Available Funds will then be allocated as provided in clauses (iii)
through (xxxi) above.


 


All distributions of
interest made in respect of a Class of the Class X Certificates on any Distribution Date pursuant to this Section 4.01(b),
shall be deemed to have been made: (x) if there is only one Component of such Class, in respect of such Component; and (y) if there
are multiple Components of such Class, in respect of all such Components, pro rata in accordance with the respective amounts
of interest that would be payable on such Components on such Distribution Date based on one-twelfth of the Class X Strip Rate
of each such Component multiplied by its respective Component Notional Amount, reduced by its share of any Excess Prepayment Interest
Shortfall for such Distribution Date, together with any amounts thereof remaining unpaid from previous Distribution Dates.


 


(c)          On
each Distribution Date, until the Notional Amounts of the Class X-A, Class X-B, and Class X-D Certificates and the Certificate
Balances of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB, Class A-S, Class B, Class C and Class D Certificates have
been reduced to zero, any amount on deposit in the Upper-Tier REMIC Distribution Account that represents a Yield Maintenance Charge
collected on the Mortgage Loans during the related Collection Period (or, in the case of any Outside Serviced Mortgage Loan(s),
that accompanied a Principal Prepayment included in the Available Funds for such Distribution Date) shall be distributed by the
Certificate Administrator to the Holders of the respective Classes of Regular Certificates (excluding the Class E-RR, Class F-RR,
Class G-RR, Class H-RR and Class J-RR Certificates) as follows: (A) first such Yield Maintenance Charge shall be allocated between
(i) the group (the “YM Group A”) of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB, Class
X-A and Class A-S Certificates, (ii) the group (the “YM Group BC”) of the Class X-B, Class B and Class
C Certificates, and (iii) the group (the “YM Group D” and, collectively with the YM Group A and the YM Group
BC, the “YM Groups”) of the Class X-D and Class D Certificates, pro rata based on the aggregate amount
of principal distributed with respect to the Class or Classes of Principal Balance Certificates in each YM Group on such Distribution
Date, and (B) then the portion of such Yield Maintenance Charge allocated to each YM Group shall be further allocated as among
the Classes of Regular Certificates in such YM Group, in the following manner: (1) each Class of Principal Balance Certificates
in such YM Group shall entitle the applicable Certificateholders to receive on the applicable Distribution Date that portion of
such Yield Maintenance Charge equal to the product of (x) a fraction, the numerator of which is the amount distributed as
principal to such Class of Principal Balance Certificates on such Distribution Date, and the denominator of which is the total
amount of principal distributed to all of the Principal Balance Certificates in such YM Group on such Distribution Date, (y) the
Base Interest Fraction for the related Principal Prepayment and such Class of Principal Balance Certificates and (z) the portion
of such Yield Maintenance Charge allocated to such YM Group; and (2) the portion of such Yield Maintenance Charge allocated to
such YM Group on any Distribution Date and remaining after such distributions with respect to the Principal Balance Certificates
contemplated by the preceding clause (1) shall be distributed to the Class of Class X Certificates in such YM Group. If there is
more than one Class of Principal Balance Certificates in any YM Group entitled to distributions of principal on any particular
Distribution Date on which Yield Maintenance Charges are distributable to such Classes, then the aggregate portion of such Yield
Maintenance Charges allocated to such YM Group shall be allocated among all such Classes of Principal


 






    	-301- 



     


    

 


Balance
Certificates up to, and on a pro rata basis in accordance with, their respective entitlements in those Yield Maintenance
Charges in accordance with the preceding sentence.


 


Notwithstanding the foregoing
provisions of this Section 4.01(c), on each Distribution Date after the Class X-A Notional Amount, the Class X-B Notional
Amount and the Class X-D Notional Amount and the Certificate Balances of the Class A-1, Class A-2, Class A-3, Class A-4, Class
A-AB, Class A-S, Class B, Class C and Class D Certificates have been reduced to zero, all amounts on deposit in the Upper-Tier
REMIC Distribution Account that represent Yield Maintenance Charges collected on the Mortgage Loans during the related Collection
Period (or, in the case of any Outside Serviced Mortgage Loan(s), that accompanied a Principal Prepayment included in the Available
Funds for such Distribution Date) shall be distributed by the Certificate Administrator to the Holders of the Class E-RR, Class
F-RR, Class G-RR, Class H-RR and Class J-RR Certificates (collectively, the “Subordinate YM Certificates”) as
follows: each such Class of Subordinate YM Certificates shall entitle the applicable Certificateholders to receive on the applicable
Distribution Date that portion of such Yield Maintenance Charge equal to the product of (x) a fraction, the numerator of which
is the amount distributed as principal to such Class of Subordinate YM Certificates on such Distribution Date, and the denominator
of which is the total amount of principal distributed to all of the Subordinate YM Certificates on such Distribution Date, and
(y) the total amount of Yield Maintenance Charges to be distributed on such Distribution Date. If there is more than one Class
of Subordinate YM Certificates entitled to distributions of principal on any particular Distribution Date on which the Yield Maintenance
Charges are distributable to such Classes, then the aggregate amount of such Yield Maintenance Charges shall be allocated among
all such Classes of Subordinate YM Certificates up to, and on a pro rata basis in accordance with, their respective entitlements
in those Yield Maintenance Charges in accordance with the preceding sentence of this paragraph.


 


Any Yield Maintenance
Charge that is to be distributed to Holders of the Regular Certificates on any Distribution Date shall be deemed to have first
been distributed from the Lower-Tier REMIC to the Upper-Tier REMIC in respect of the Lower-Tier Regular Interests then receiving
a principal distribution, pro rata, based on the respective amounts of those principal distributions.


 


(d)          On
each Distribution Date, the Certificate Administrator shall withdraw amounts from the Excess Liquidation Proceeds Reserve Account
and shall distribute such amounts in the following priority:


 


(i)          first,
to the Holders of the Regular Certificates (in the same order as distributions are made pursuant to Section 4.01(b)
of this Agreement) up to an amount equal to all amounts remaining due and payable on the Regular Certificates, and any Realized
Loss allocable to such Certificates, after application of the Available Funds for such Distribution Date; and


 


(ii)          second,
to the Holders of the Class R Certificates, in accordance with the last sentence of Section 3.05(c) of this Agreement.


 


Amounts paid with respect
to the Mortgage Loans from the Excess Liquidation Proceeds Reserve Account pursuant to the preceding clause (i) shall
first be deemed to have been distributed to reimburse the Lower-Tier REMIC in respect of any Realized Losses or other


 






    	-302- 



     


    

 


shortfalls
allocated to the Upper-Tier REMIC in respect of the Lower-Tier Regular Interests in reimbursement of Realized Losses previously
allocated thereto and payment of other amounts due thereon.


 


(e)          On
each Distribution Date, following the deemed distributions of principal or in reimbursement of previously allocated Realized Losses
made in respect of the Lower-Tier Regular Interests pursuant to Section 4.01(a)(ii), the Lower-Tier Principal Balance
of each Lower-Tier Regular Interest (after taking account of such deemed distributions) shall be reduced as a result of Realized
Losses to equal the Certificate Balance of its Corresponding Certificates that will be outstanding immediately following such Distribution
Date.


 


(f)          
The Certificate Balance of each Class of Principal Balance Certificates will be reduced without distribution on any Distribution
Date, as a write-off, to the extent of any Realized Loss allocated to such Class of Certificates, on such Distribution Date. On
each Distribution Date, any Realized Loss for such Distribution Date will be allocated to the following Classes of Principal Balance
Certificates in the following order, until the Certificate Balance of each such Class of Certificates is reduced to zero: first,
to the Class J-RR Certificates; second, to the Class H-RR Certificates; third, to the Class G-RR Certificates; fourth,
to the Class F-RR Certificates; fifth, to the Class E-RR Certificates; sixth, to the Class D Certificates; seventh,
to the Class C Certificates; eighth, to the Class B Certificates; ninth, to the Class A-S Certificates; and,
finally, pro rata to the (i) Class A-1 Certificates, (ii) Class A-2 Certificates, (iii) Class A-3
Certificates, (iv) Class A-4 Certificates and (v) Class A-AB Certificates based on their respective Certificate
Balances.


 


Distributions in reimbursement
of Realized Losses previously allocated to the respective Classes of the Principal Balance Certificates shall be made in the amounts
and manner specified in Section 4.01(b). Reimbursement of previously allocated Realized Losses will not constitute distributions
of principal for any purpose and will not result in an additional reduction in the Certificate Balance of the Class of Principal
Balance Certificates in respect of which any such reimbursement is made. If and to the extent that any Nonrecoverable Advances
(plus interest thereon) that were reimbursed from principal collections on the Mortgage Loans (including REO Mortgage Loans) and
previously resulted in a reduction of the Principal Distribution Amount are subsequently recovered on the related Mortgage Loan
or REO Property, then (on the Distribution Date related to the Collection Period during which the recovery occurred) the amount
of such recovery will be added to the Certificate Balance(s) of the Class or Classes of Principal Balance Certificates that
previously were allocated Realized Losses, in the same sequential order as distributions pursuant to Section 4.01(b)
of this Agreement, in each case up to the lesser of the unallocated portion of such recovery and the amount of the unreimbursed
Realized Losses previously allocated to the subject Class of Certificates, and the Interest Shortfall with respect to each affected
Class of Regular Certificates for the next Distribution Date will be increased by the amount of interest that would have accrued
through the then current Distribution Date if the restored write-down for such Class of Principal Balance Certificates had never
been written down (and, to the extent that the Certificate Balance of, and/or any interest payable on, any Class of Regular Certificates
is so increased, an identical increase shall be deemed made to the Lower-Tier Principal Balance of, and any interest payable on,
the Corresponding Lower-Tier Regular Interest). If the Certificate Balance of any Class of Principal Balance Certificates (or the
Lower-Tier Principal Balance of any Lower-Tier Regular Interest) is so increased, the amount of unreimbursed


 






    	-303- 



     


    

 


Realized
Losses of such Class of Certificates (or such Lower-Tier Regular Interest, as the case may be) shall be decreased by such amount.


 


The Notional Amount of
the Class X-A Certificates and the Component Notional Amounts of the Class X-A Components will be reduced to reflect reductions
of the Certificate Balances of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB and Class A-S
Certificates and of the Lower-Tier Principal Balances of the Class LA-1, Class LA-2, Class LA-3, Class LA-4,
Class LA-AB and Class LA-S Lower-Tier Regular Interests, in any event resulting from allocations of Realized Losses.
The Notional Amount of the Class X-B Certificates and the Component Notional Amounts of the Class X-B Components will be reduced
to reflect reductions of the Certificate Balances of the Class B and Class C Certificates and of the Lower-Tier Principal
Balances of the Class LB and Class LC Lower-Tier Regular Interests, in any event resulting from allocations of Realized Losses.
The Notional Amount of the Class X-D Certificates and the Component Notional Amount of the Class X-D Component will be reduced
to reflect reductions of the Certificate Balance of the Class D Certificates and of the Lower-Tier Principal Balance of the Class
LD Lower-Tier Regular Interest, in any event resulting from allocations of Realized Losses.


 


(g)          All
amounts distributable, or reductions allocable on account of Realized Losses, to a Class of Certificates pursuant to this Section 4.01
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 by the Certificate Administrator on each Distribution Date other
than the Termination 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with
written wiring instructions no less than five (5) Business Days prior to the related Record Date (which wiring instructions may
be in the form of a standing order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder.
The final distribution on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution. The Certificate
Administrator shall be responsible for making all distributions on the Certificates contemplated hereunder.


 


(h)          Except
as otherwise provided in Section 9.01 with respect to an Anticipated Termination Date, the Certificate Administrator
shall, no later than the fifteenth day of the month preceding the month in which the final distribution with respect to any Class
of Certificates is expected to be made (or, if the Certificate Administrator has not received notice of such Anticipated Termination
Date by such time, promptly following the Certificate Administrator’s receipt of such notice), 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 will 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


 






    	-304- 



     


    

 


(ii)          if
such final distribution is made on such Distribution Date, no interest shall accrue on such Class of Certificates, or on the Corresponding
Lower-Tier Regular Interest, from and after such Distribution Date;


 


provided, however, that the
Class R Certificates shall remain outstanding until there is no other Class of Certificates outstanding.


 


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 4.01(h) shall not
have been surrendered for cancellation within six (6) months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation 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. Subject to applicable state
law with respect to escheatment of funds, if within two years after the second notice any such Certificates shall not have been
surrendered for cancellation, the Paying Agent shall pay to the Certificate Administrator all amounts distributable to the Holders
thereof, and the Certificate Administrator shall thereafter hold such amounts 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 and distribution of such amounts to the Class R Certificateholders.
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 4.01(h). Any funds not distributed on such Distribution Date shall be set aside and held uninvested in
trust for the benefit of Certificateholders not presenting and surrendering their Certificates in the aforesaid manner.


 


(i)          The
Excess Prepayment Interest Shortfall, if any, for each Distribution Date will be allocated among the various Classes of Regular
Certificates, pro rata, based upon the respective Interest Accrual Amounts with respect to such Classes of Regular Certificates
for such Distribution Date. The portion of any Excess Prepayment Interest Shortfall for any Distribution Date so allocable to a
Class of Class X Certificates shall, in turn, be allocated among the various Components of such Class of Class X Certificates,
pro rata, based upon the respective amounts of Accrued Component Interest with respect to such Components for such Distribution
Date. The portion of any Excess Prepayment Interest Shortfall for any Distribution Date so allocated to any Class of Principal
Balance Certificates or any Component of a Class of Class X Certificates shall be deemed to have first been allocated to the
Corresponding Lower-Tier Regular Interest for such Class of Principal Balance Certificates or such Component, as applicable.


 


(j)          On
each Distribution Date, the Certificate Administrator shall withdraw from the Excess Interest Distribution Account any amounts
on deposit therein that represent Excess Interest received during the related Collection Period (or, in the case of an ARD Mortgage


 






    	-305- 



     


    

 


Loan
that is an Outside Serviced Mortgage Loan, received as of the close of business on the Business Day immediately preceding the
related Master Servicer Remittance Date and not previously distributed) with respect to the ARD Mortgage Loans and shall distribute
such Excess Interest to the Holders of the Class S Certificates.


 


(k)          The
various amounts distributable on any Class of Certificates on any Distribution Date pursuant to multiple subsections of, or multiple
clauses of any subsection of, this Section 4.01 shall be so distributed in a single, aggregate distribution to the Holders
of such Class of Certificates on such Distribution Date.

Notwithstanding the foregoing,

the Controlling Class Representative or any Controlling Class Certificateholder from receiving, requesting or reviewing any Excluded
Information relating to any Excluded Controlling Class Mortgage Loan with respect to which the Controlling Class Representative
or such Controlling Class Certificateholder is not a Borrower Party and, if such Excluded Information is not available to such

Controlling Class Representative or Controlling Class Certificateholder that is not a Borrower Party with respect to the related

Notwithstanding any of
the foregoing to the contrary, if the Special Servicer acquires knowledge that it is a Borrower Party with respect to any Mortgage

include,
without limitation, any Excluded Information related to such Excluded Special Servicer Mortgage Loan) to (A) any related Borrower
Party, (B) any employees or personnel of the Special Servicer or any of its Affiliates involved in the management of any investment
in any related Borrower Party or the related Mortgaged Property or (C) to the extent known to the Special Servicer, any non-Affiliate
that holds a direct or indirect ownership interest in any related Borrower Party or the related Mortgaged Property, and (ii) shall
maintain sufficient internal controls and appropriate policies and procedures in place in order to comply with the obligations
described in clause (i) above. Notwithstanding any provision to the contrary herein, the Certificate Administrator shall not have

or a Controlling Class Certificateholder, if any such Person is an Excluded Controlling Class Holder, upon delivery to the Master
Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee in physical form of an Investor
Certification substantially in the form of Exhibit M-1C and a notice in the form of Exhibit M-1F hereto certifying
to the effect that it is an Excluded Controlling Class Holder and upon delivery to the Certificate Administrator in physical form
of an investor certification substantially in the form of Exhibit M-1G, which shall include each of the CitiDirect Login
User ID associated with such Excluded Controlling Class Holder, all information (other than Excluded Information related to the
Excluded Controlling Class Mortgage Loan(s) (unless a loan-by-loan segregation is later performed by the Certificate Administrator
in which case such access shall only be prohibited with respect to the Excluded Controlling Class Mortgage Loan(s) for which such
Person is a Borrower Party)) available on the Certificate Administrator’s Website.


 


In the case of the Controlling
Class Representative or Controlling Class Certificateholder that is not an Excluded Controlling Class Holder, upon delivery of
an investor certification substantially in the form of Exhibit M-1B hereto certifying to the effect that it is not an Excluded
Controlling Class Holder, such Controlling Class Representative or a Controlling Class Certificateholder shall be entitled to access
all information on the Certificate Administrator’s Website. The Master Servicer, Special Servicer, Operating Advisor, Certificate
Administrator and Trustee may each rely on (i) an Investor Certification in the form of Exhibit M-1B hereto from the Controlling
Class Representative or a Controlling Class Certificateholder to the effect that such Person is not an Excluded Controlling Class
Holder with respect to any Excluded Controlling Class Mortgage Loan or (ii) an Investor Certification in the form of Exhibit
M-1C hereto from the Controlling Class Representative or a Controlling Class Certificateholder to the effect that such Person
is an Excluded Controlling Class Holder with respect to one or more Excluded Controlling Class Mortgage Loan(s). In the event the
Controlling Class Representative or a Controlling Class Certificateholder, as the case may be, becomes an Excluded Controlling
Class Holder, such party shall promptly notify each of the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate
Administrator and the Trustee in writing substantially in the form of Exhibit M-1F to the effect that such party is an Excluded
Controlling Class Holder with respect to the Excluded Controlling Class Mortgage Loan(s) listed in such notice and shall also provide
the Certificate Administrator a notice substantially in the form of Exhibit M-1G listing the CitiDirect Login User ID associated
with such Excluded Controlling Class Holder and directing the Certificate

Administrator
to restrict such Excluded Controlling Class Holder’s access to the Certificate Administrator’s Website as and to the
extent provided in this Agreement. Upon confirmation from the Certificate Administrator that such access has been restricted,
such Excluded Controlling Class Holder shall submit a new investor certification substantially in the form of Exhibit M-1C
(which certification shall include, among other things, an acknowledgement and agreement by such Excluded Controlling Class
Holder that it is prohibited from accessing and reviewing (and it agrees not to access and review) any Excluded Information with
respect to any Excluded Controlling Class Mortgage Loans for which it is a Borrower Party) to access the information on the Certificate
Administrator’s Website, except that such Excluded Controlling Class Holder shall not be entitled to access any Excluded
Information related to any Excluded Controlling Class Mortgage Loan(s) (unless a loan-by-loan segregation is later performed by
the Certificate Administrator in which case such access shall only be prohibited with respect to the Excluded Controlling Class
Mortgage Loan(s) for which such Person is a Borrower Party) made available on the Certificate Administrator’s Website. Any
Excluded Information relating to an Excluded Controlling Class Mortgage Loan that the Master Servicer, the Special Servicer or
the Operating Advisor identifies and delivers to the Certificate Administrator for posting to the Certificate Administrator’s
Website shall be delivered to the Certificate Administrator via email to loandata@citi.com in one or more separate files
labeled “Excluded Information” followed by the applicable loan name and loan number, and the Certificate Administrator
shall segregate on the Certificate Administrator’s Website such Excluded Information on a separate excluded loan tab on
the Certificate Administrator’s website (and, if possible at a later time, on a loan-by-loan basis). Notwithstanding anything
herein to the contrary, each of the Master Servicer, the Special Servicer, the Operating Advisor and the Certificate Administrator
shall be entitled to conclusively assume that the Controlling Class Representative and all Controlling Class Certificateholders
are not Excluded Controlling Class Holders except to the extent that the Master Servicer, the Special Servicer, the Operating
Advisor or the Certificate Administrator, as applicable, has received notice from the Controlling Class Representative or a Controlling
Class Certificateholder that it has become an Excluded Controlling Class Holder. None of the Master Servicer, the Special Servicer,
the Operating Advisor or the Certificate Administrator shall be liable for any communication to the Controlling Class Representative
or Controlling Class Certificateholder or disclosure of Excluded Information if the Master Servicer, the Special Servicer, the
Operating Advisor or the Certificate Administrator, as applicable, did not receive prior written notice that the related Mortgage
Loan is an Excluded Controlling Class Mortgage Loan (including, in the case of the summary of any Asset Status Report or the summary
of any Final Asset Status Report delivered to the Certificate Administrator for posting to the Certificate Administrator’s
Website and/or any failure to label any such information provided to the Certificate Administrator).


 


Each of the Master Servicer,
the Special Servicer, the Operating Advisor and the Certificate Administrator shall be entitled to conclusively rely on any certification
delivered by the Controlling Class Representative or a Controlling Class Certificateholder, as applicable, substantially in the
form of Exhibit M-1B to the effect that such Person is no longer an Excluded Controlling Class Holder. To the extent the
Controlling Class Representative or a Controlling Class Certificateholder receives access pursuant to this Agreement to any Excluded
Information with respect to a related Excluded Controlling Class Mortgage Loan on the Certificate Administrator’s Website
or otherwise receives access to such Excluded Information, such Controlling Class Representative or Controlling Class Certificateholder
shall be deemed to have agreed that it (i) will not directly or indirectly provide any information related to the Excluded

Controlling
Class Mortgage Loan to (A) any related Borrower Party, (B) any Excluded Controlling Class Holder, (C) any employees or personnel
of such Controlling Class Representative or Controlling Class Certificateholder, (D) any Affiliate involved in the management
of any investment in any related Borrower Party or the related Mortgaged Property or (E) to its actual knowledge, any non-Affiliate
that holds a direct or indirect ownership interest in any related Borrower Party, and (ii) will maintain sufficient internal controls
and appropriate policies and procedures in place in order to comply with the obligations described in clause (i) above.

by the Certificate Administrator for which it is not the original source. In connection with providing access to the Certificate
Administrator’s internet website, the Certificate Administrator may require registration and acceptance of a disclaimer and
may require a recipient of any of the information set forth above (other than the Public Documents) to execute a confidentiality
agreement (which may be in the form of a web page “click-through”). The Certificate Administrator shall not be liable
for the dissemination of information in accordance with this Agreement. Notwithstanding anything herein to the contrary, the Certificate
Administrator shall not be liable for any disclosure of Excluded Information relating to an Excluded Controlling Class Mortgage
Loan to the extent such information was included in the summary of any Asset Status Report or the summary of any Final Asset Status
Report delivered to the Certificate Administrator for posting to the Certificate Administrator’s Website and not properly
identified as relating to an Excluded Controlling Class Mortgage Loan.


 


The Certificate Administrator
shall have no liability for access by an Excluded Controlling Class Holder to the Certificate Administrator’s website of
any information with respect to which such Excluded Controlling Class Holder is prohibited from accessing pursuant to this Agreement
if such Excluded Controlling Class Holder provided an Investor Certification but did not indicate it was a Borrower Party.


 


The Certificate Administrator
shall provide assistance in using the Certificate Administrator’s Website through the Certificate Administrator’s customer
service desk at telephone number 1-888-855-9695.


 


The Certificate Administrator

that (i) the Depositor shall have consented to such alternative means and (ii) Certificateholders and each of the Serviced
Companion Loan Holders shall have received notice of such alternative means (which notice may be given via the Certificate Administrator’s
Website).

access only the Prospectus, Distribution Date Statements, this Agreement, the Mortgage Loan Purchase Agreements and the Commission

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


 


The Certificate Administrator
shall make available, only to Privileged Persons, the Investor Q&A Forum. The “Investor Q&A Forum” shall
be a service available on the Certificate Administrator’s Website, where Certificateholders and Certificate Owners that are
Privileged Persons may submit questions to (a) the Certificate Administrator relating to the Distribution Date Statements, (b) the
Master Servicer or the Special Servicer, as applicable, relating to the servicing reports prepared by that party and being made
available pursuant to this Section 4.02(a), the Mortgage Loans (excluding the Outside Serviced Mortgage Loans) or the
related Mortgaged Properties or (c) the Operating Advisor relating to the Operating Advisor Annual Reports or other reports
prepared by the Operating Advisor or actions by the Special Servicer referenced in such reports (collectively, “Inquiries”),
and (ii) Privileged Persons may view Inquiries that have been previously submitted and answered, together with the answers
thereto. Upon receipt of an Inquiry for the Operating Advisor, the Master Servicer or the Special Servicer, as applicable, the
Certificate Administrator shall forward the Inquiry to the appropriate Person and, in the case of an inquiry relating to an Outside
Serviced Mortgage Loan, to the applicable party under the related Outside Servicing Agreement, in each case within a commercially
reasonable period following receipt thereof.


 


Within a commercially
reasonable time following receipt of an Inquiry, the Certificate Administrator, the Operating Advisor, the Master Servicer or the
Special Servicer, as applicable, unless it determines not to answer such Inquiry as provided below, shall reply to the Inquiry,
which reply of the Operating Advisor, the Master Servicer or Special Servicer shall be by e-mail to the Certificate Administrator.
In the case of an Inquiry relating to an Outside Serviced Mortgage Loan, the Certificate Administrator shall make reasonable efforts
to obtain an answer from the related Outside Servicer or the related Outside Special Servicer, as applicable; provided that
the Certificate Administrator shall not be responsible for the content of such answer or any delay or failure to obtain such answer.
The Certificate Administrator shall post (within a commercially reasonable period following preparation or receipt of such answer,
as the case may be) such Inquiry and the related answer to the Certificate Administrator’s Website. If the Certificate Administrator,
the Operating Advisor, the Master Servicer or the Special Servicer determines, in its respective sole discretion, that (i) any
Inquiry is beyond the scope of the topics described above, (ii) answering any Inquiry would not be in the best interests of
the Trust and/or the Certificateholders, (iii) answering any Inquiry would be in violation of applicable law, this Agreement
(including requirements in respect of non-disclosure of Privileged Information) or the applicable Loan Documents, (iv) answering
any Inquiry would materially increase the duties of, or result in significant additional cost or expense to, the Certificate Administrator,
the Operating

Advisor,
the Master Servicer or the Special Servicer, as applicable, (v) answering any Inquiry would require the disclosure of Privileged
Information (subject to the Privileged Information Exception) or (vi) answering any Inquiry is otherwise, for any reason,
not advisable, then it shall not be required to answer such Inquiry and, in the case of the Operating Advisor, the Master Servicer
or the Special Servicer, shall promptly notify the Certificate Administrator of such determination. In addition, no party shall
post or otherwise disclose any direct communications with the Directing Holder as part of its response to any Inquiries. The Certificate
Administrator shall notify the Person who submitted such Inquiry in the event that the Inquiry will not be answered. The Certificate
Administrator shall not be required to post to the Certificate Administrator’s Website any Inquiry or answer thereto that
the Certificate Administrator determines, in its sole discretion, is administrative or ministerial in nature. The Investor Q&A
Forum will not reflect questions, answers and other communications which are not submitted via the Certificate Administrator’s
Website. Answers posted on the Investor Q&A Forum shall be attributable only to the respondent, and shall not be deemed to
be answers from any of the Depositor, the Underwriters, the Initial Purchasers or any of their respective Affiliates. None of
the Underwriters, Initial Purchasers, Depositor, any of their respective affiliates or any other person will certify as to the
accuracy of any of the information posted in the Investor Q&A Forum and no such person will have any responsibility or liability
for the content of any such information. No party to this Agreement shall disclose Privileged Information in the Investor Q&A
Forum.


 


The Certificate Administrator
shall make available to any Certificateholder and any Certificate Owner that is a Privileged Person, the Investor Registry. The
“Investor Registry” shall be a voluntary service available on the Certificate Administrator’s Website,
where Certificateholders and Certificate Owners can register and thereafter obtain information with respect to any other Certificateholder
or Certificate Owner that has so registered. Any person registering to use the Investor Registry will be required to certify that
(a) it is a Certificateholder or a Certificate Owner and (b) it grants authorization to the Certificate Administrator
to make its name and contact information available on the Investor Registry for at least 45 days from the date of such certification
to other registered Certificateholders and registered Certificate Owners. Such Person shall then be asked to enter certain mandatory
fields such as the individual’s name, the company name and e-mail address, as well as certain optional fields such as address,
phone, and Class(es) of Certificates owned. If any Certificateholder or Certificate Owner notifies the Certificate Administrator
that it wishes to be removed from the Investor Registry (which notice may not be within 45 days of its registration), the Certificate
Administrator shall promptly remove it from the Investor Registry. The Certificate Administrator will not be responsible for verifying
or validating any information submitted on the Investor Registry, or for monitoring or otherwise maintaining the accuracy of any
information thereon. The Certificate Administrator may require acceptance of a waiver and disclaimer for access to the Investor
Registry.


 


Notwithstanding the foregoing,
in no event shall any provision of this Agreement be construed to require the Master Servicer, the Special Servicer or the Certificate
Administrator to produce any ad hoc or non-standard written reports (in addition to the CREFC® reports, inspection
reports, reports required under each Co-Lender Agreement and other specific periodic reports otherwise required). If the Master
Servicer, the Special Servicer or the Certificate Administrator elects to provide any ad hoc or non-standard reports, it may require
the Person requesting such report to pay a reasonable fee to cover the costs of the preparation thereof.

Class R Certificates may reasonably request.


 


The
specification of information to be furnished by the Certificate Administrator in this Section 4.02 (and any other terms
of this Agreement requiring or calling for delivery or reporting of information by the Certificate Administrator to Certificateholders
and Certificate Owners) shall not limit the Certificate Administrator in furnishing, and the Certificate Administrator is
hereby authorized to furnish, to any Privileged Person any other information (such other information, collectively, “Additional
Information”) with respect to the Mortgage Loans or Serviced Loan Combination, the Mortgaged Properties or the
Trust Fund as may be provided to it by the Depositor, the Master Servicer or the Special Servicer or gathered by it in any investigation
or other manner from time to time, provided that (A) while there exists any Servicer Termination Event, any such Additional
Information shall only be furnished with the consent or at the request of the Depositor (except pursuant to clause (E) below
or to the extent such information is requested by a Certifying Certificateholder), (B) the Certificate Administrator shall
be entitled to indicate the source of all information furnished by it, and the Certificate Administrator may affix thereto any
disclaimer it deems appropriate in its sole discretion (together with any warnings as to the confidential nature and/or the uses
of such information as it may, in its sole discretion, determine appropriate), (C) the Certificate Administrator may notify
any Privileged Person of the availability of any such information in any manner as it, in its sole discretion, may determine,
(D) the Certificate Administrator shall be entitled (but not obligated) to require payment from each recipient of a reasonable
fee for, and its out-of-pocket expenses incurred in connection with, the collection, assembly, reproduction or delivery of any
such Additional Information, and (E) the Certificate Administrator shall be entitled to distribute or make available such
Additional Information in accordance with such reasonable rules and procedures as it may deem necessary or appropriate (which
may include the requirement that an agreement that provides such information shall be used solely for purposes of evaluating the
investment characteristics or valuation of the Certificates be executed by the recipient, if and to the extent the Certificate
Administrator deems the same to be necessary or appropriate). Nothing herein shall be construed to impose upon the Certificate
Administrator any obligation or duty to furnish or distribute any Additional Information to any Person in any instance, and the
Certificate Administrator shall neither have any liability for furnishing nor for refraining from furnishing Additional Information
in any instance. The Certificate Administrator shall be entitled (but not required) to request and receive direction from the
Depositor as to the manner of delivery of any such Additional Information, if and to the extent the Certificate Administrator
deems necessary or advisable, and to require that any consent, direction or request given to it pursuant to this Section be

Initial Schedule AL Additional File from the Depositor in EDGAR-Compatible Format and Excel format; and provided, further,
that, if the Master Servicer has not received the Initial Schedule AL File and the Initial Schedule AL Additional File from the
Depositor prior to the time it would need the Initial Schedule AL File and the Initial Schedule AL Additional File in order for
the Master Servicer to prepare the CREFC® Schedule AL File with respect to the first Distribution Date, the Master
Servicer shall request the Initial Schedule AL File and the Initial Schedule AL Additional File from the Depositor, including
by email to the email addresses for the Depositor set forth in Section 12.04. If the CREFC® Schedule AL
File is not provided by the Master Servicer to the Certificate Administrator by 5:00 p.m. (New York City time) on any Distribution
Date, the Certificate Administrator shall notify the Depositor in writing and also request such CREFC® Schedule
AL File from the Master Servicer via email to NoticeAdmin@midlandls.com. The Master Servicer shall be entitled to conclusively
rely, absent manifest error, without any due diligence, investigation or verification, on the content, completeness and accuracy
of the Initial Schedule AL File and the Initial Schedule AL Additional File, in each case, as of the Closing Date. Any Schedule
AL Additional File that the Master Servicer determines, in accordance with the Servicing Standard, to deliver in connection with
any CREFC® Schedule AL File prepared by the Master Servicer pursuant to this paragraph shall be delivered in EDGAR-Compatible
Format and in Excel format to the Certificate Administrator concurrently with the delivery of the related CREFC®
Schedule AL File. With respect to each Outside Serviced Mortgage Loan, the Master Servicer shall include the analogous CREFC®
Schedule AL File and/or Schedule AL Additional File, as applicable, information that it receives from the related Outside
Servicer under the applicable Outside Servicing Agreement in the single CREFC® Schedule AL File and/or Schedule
AL Additional File, as applicable, that it delivers to the Certificate Administrator for the subject Distribution Date.


 


In
addition, the Master Servicer (with respect to Performing Serviced Loans) or Special Servicer (with respect to Specially Serviced
Loans and REO Properties), as applicable, shall prepare the following with respect to each Mortgaged Property and REO Property,
in each case other than with respect to any Outside Serviced Mortgage Loan:


 






    	-320- 



     


    

 


(i)         
  Within 30 days after receipt of a quarterly operating statement, if any, for each calendar quarter, commencing with respect
to the calendar quarter ending March 31, 2018, a CREFC® Operating Statement Analysis Report (but only to the extent
the related Mortgagor is required by the related Loan Documents to deliver and does deliver, or otherwise agrees to provide and
does provide, such information) for such Mortgaged Property or REO Property as of the end of such calendar quarter; provided,
however, that any analysis or report with respect to the first calendar quarter of each year shall not be required to the
extent provided in the then current applicable CREFC® guidelines (it being understood that as of the Closing Date, the applicable
CREFC® guidelines provide that such analysis or report with respect to the first calendar quarter (in each year) is not required
for a Mortgaged Property unless such Mortgaged Property is analyzed on a trailing 12-month basis, or if the related Serviced Mortgage
Loan is on the CREFC® Servicer Watch List). The Master Servicer (with respect to Performing Serviced Loans) or Special Servicer
(with respect to Specially Serviced Loans and REO Properties), as applicable, shall deliver to the Certificate Administrator,
the Operating Advisor and each related Serviced Companion Loan Holder (or the master servicer or special servicer for the related
Other Securitization Trust on its behalf) by electronic means the CREFC® Operating Statement Analysis Report upon
request; and


 


(ii)          
Within 30 days after receipt by the Special Servicer (with respect to Specially Serviced Loans and REO Properties) or the
Master Servicer (with respect to Performing Serviced Loans) of any annual operating statement or rent rolls, commencing with respect
to the calendar year ending December 31, 2018, a CREFC® NOI Adjustment Worksheet (but only to the extent the
related Mortgagor is required by the related Loan Documents to deliver and does deliver, or otherwise agrees to provide and does
provide, such information), presenting the computation to “normalize” the full year net operating income and debt
service coverage numbers used by the Master Servicer in preparing the CREFC® Comparative Financial Status Report
above. The Special Servicer or the Master Servicer shall deliver to the Certificate Administrator, the Operating Advisor and each
related Serviced Companion Loan Holder (or the master servicer or special servicer for the related Other Securitization Trust
on its behalf) by electronic means the CREFC® NOI Adjustment Worksheet upon request.


 


Notwithstanding
anything to the contrary contained herein, with respect to any Serviced Loan related to any Significant Obligor, (a) the Master
Servicer (with respect to Performing Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans and REO
Properties) shall be required to complete (and, in the case of the Special Servicer, to deliver to the Master Servicer) any CREFC
files, reports and/or templates necessary in order to comply with (or, in the case of the Special Servicer, to facilitate compliance
with) the Master Servicer’s obligations under Section 10.11 of this Agreement and the Exchange Act filing obligations
of the Depositor and/or any Other Depositor, as applicable, with respect to such Significant Obligor.


 


The
Certificate Administrator shall deliver or shall cause to be delivered, upon request, to the Rule 17g-5 Information Provider (for
posting to the Rule 17g-5 Information Provider’s Website pursuant to Section 12.13 of this Agreement), to each

Upon
request (and in any event, not more frequently than once per month), the Master Servicer shall forward to the Certificate Administrator
(as to the Collection Account), the Operating Advisor, any related Serviced Companion Loan Holder or the master servicer or special
servicer for the related Other Securitization Trust on its behalf (as to the related Loan Combination Custodial Account) and,
for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section 12.13 of this Agreement, the Rule
17g-5 Information Provider a statement, setting forth the status of the Collection Account and each Loan Combination Custodial
Account as of the close of business on such Master Servicer Remittance Date, stating that all remittances to the Certificate Administrator
required by this Agreement to be made by the Master Servicer have been made (or, in the case of any such required remittance that
has not been made by the Master Servicer, specifying the nature and status thereof) and showing, for the period from the preceding
Master Servicer Remittance Date (or, in the case of the first Master Servicer Remittance Date, from the Cut-Off Date) to such
Master Servicer Remittance Date, the aggregate of deposits into and withdrawals from the Collection Account and each Loan Combination
Custodial Account for each category of deposit specified in Section 3.05(a) of this Agreement and each category of
withdrawal specified in Section 3.06 of this Agreement. The Master Servicer shall also deliver to the Certificate
Administrator and (solely as to a Serviced Loan Combination) the related Serviced Companion Loan Holder, upon reasonable request
of the Certificate Administrator or any Serviced Companion Loan Holder, any and all additional information relating to the Mortgage
Loans or Serviced Loan Combinations in the possession of the Master Servicer (which information shall be based upon reports delivered
to the Master Servicer by the Special Servicer with respect to Specially Serviced Loans and REO Properties).


 


Further,
the Master Servicer shall cooperate with the Special Servicer and provide the Special Servicer with the information in the possession
of the Master Servicer reasonably requested by the Special Servicer, in writing, to the extent required to allow the Special Servicer

to the Master Servicer having received from the Special Servicer in a timely manner the related reports and information in the
possession of the Special Servicer necessary or required to enable the Master Servicer to prepare and deliver such reports. The
Master Servicer shall not be responsible for the accuracy or content of any report, document or information furnished by the Special
Servicer to the Master Servicer pursuant to this Agreement and accepted by the Master Servicer in good faith pursuant to this
Agreement.


 


The
obligation of the Special Servicer to deliver the reports required to be delivered by it pursuant to this subsection is subject
to the Special Servicer having received from the Master Servicer in a timely manner the related reports and information in the

    	-322- 



     


    

 


or information furnished by the
Master Servicer to the Special Servicer pursuant to this Agreement and accepted by the Special Servicer in good faith pursuant
to this Agreement.


 


With
respect to an Outside Serviced Mortgage Loan, the Master Servicer shall deliver information comparable to the above-described
information to the same Persons as described above in this Section 4.02(b) and according to the same time frames as
described above in this Section 4.02(b), with reasonable promptness following such Master Servicer’s receipt
of such information from the related Outside Servicer under the applicable Outside Servicing Agreement.


 


(c)            
Not later than 5:00 p.m. New York time on each Determination Date, the Special Servicer shall forward to the Master Servicer,
for each Specially Serviced Loan and REO Property (other than an REO Property related to an Outside Serviced Mortgage Loan), a
CREFC® Special Servicer Loan File. The Special Servicer shall also deliver to the Certificate Administrator, upon
the reasonable written request of the Certificate Administrator, any and all additional information in the possession of the Special
Servicer relating to the Specially Serviced Loans and the REO Properties (other than an REO Property related to an Outside Serviced
Mortgage Loan).


 


The
Special Servicer shall cooperate with the Master Servicer and provide the Master Servicer with the information in the possession
of the Special Servicer reasonably requested by the Master Servicer, in writing, to the extent required to allow the Master Servicer
to perform its obligations under this Agreement with respect to the Specially Serviced Loans and REO Properties (other than an
REO Property related to an Outside Serviced Mortgage Loan).


 


The
Master Servicer may make available to Privileged Persons copies of any reports or files prepared by the Master Servicer pursuant
to this Agreement. The Master Servicer may make information concerning the Mortgage Loans or Serviced Loan Combination available
on any website that it has established.


 


With
respect to an Outside Serviced Mortgage Loan, the Master Servicer shall deliver information comparable to the above-described
information to the extent received from the related Outside Servicer or the related Outside Special Servicer, as applicable, to
the same Persons as described above in this Section 4.02(c) and according to the same time frames as described above
in this Section 4.02(c), with reasonable promptness following such Master Servicer’s receipt of such information
from the related Outside Servicer under the related Outside Servicing Agreement.


 


Upon
the reasonable request of (i) any Certificateholder or Certificate Owner that has delivered an appropriate Investor Certification
or (ii) any other Privileged Person so identified by a Certificate Owner or an Underwriter, the Master Servicer shall provide
(or forward electronically) at the expense of such Privileged Person, Certificateholder or Certificate Owner, as applicable, copies
of any appraisals, operating statements, rent rolls and financial statements obtained by the Master Servicer; provided that in
no event shall an Excluded Controlling Class Holder be entitled to Excluded Information with respect to an Excluded Controlling
Class Mortgage Loan with respect to which it is a Borrower Party; and provided, further, that no Certificateholders or Certificate
Owners shall be given access to or be provided copies of, any Mortgage Files or Diligence Files. In connection with such request,
the Master Servicer may require (1) a written confirmation executed by the requesting Person substantially in such form as


 






    	-323- 



     


    

 


may
be reasonably acceptable to the Master Servicer, generally to the effect that (a) such Person will keep such information confidential
and will use such information only for the purpose of analyzing asset performance and evaluating any continuing rights the Certificateholder
or Certificate Owner may have under this Agreement and (b) if the requesting party is neither a Certificateholder nor a Certificate
Owner, such Person is Privileged Person, and (2) payment of a sum sufficient to cover the reasonable costs and expenses of providing
copies of such reports or information (which amounts in any event are not reimbursable as Additional Trust Fund Expenses), except
that, other than for extraordinary or duplicate requests, the Directing Holder (but, in the case of the Controlling Class Representative,
only if a Consultation Termination Event does not exist) will be entitled to reports and information free of charge. For the avoidance
of doubt, the Master Servicer shall not make any Asset Status Reports or Final Asset Status Reports available to any Certificateholders
or Certificate Owners on its website. None of the parties to this Agreement shall provide any Asset Status Report or any Final
Asset Status Report to the Certificate Administrator (provided that the Special Servicer shall provide a summary of each
Final Asset Status Report to the Certificate Administrator pursuant to Section 3.21(b)). If the Certificate Administrator
receives any Asset Status Report or any Final Asset Status Report, the Certificate Administrator shall not provide any such Asset
Status Report or any Final Asset Status Report to any Certificateholder or Certificate Owners and shall not post any such Asset
Status Report or any Final Asset Status Report to the Certificate Administrator’s Website.


 


(d)           
The Master Servicer shall withdraw from the Collection Account and pay the CREFC® Intellectual Property Royalty
License Fee to CREFC® in accordance with Section 3.06(a)(vi) on a monthly basis, from funds on deposit
in the Collection Account.


 


(e)            
Upon the reasonable request of the Controlling Class Representative or any Controlling Class Certificateholder that, in either
case, is an Excluded Controlling Class Holder with respect to any Excluded Controlling Class Mortgage Loan identified to the Master
Servicer’s (in the case of a Performing Serviced Loan) or the Special Servicer’s (in the case of a Specially Serviced
Loan) reasonable satisfaction (at the expense of the Controlling Class Representative or such Controlling Class Certificateholder)
and if such information is in the Master Servicer’s or Special Servicer’s possession, as applicable, the Master Servicer
or Special Servicer, shall provide or make available (or forward electronically) to the Controlling Class Representative or such
Controlling Class Certificateholder, as applicable, (at the expense of the Controlling Class Representative or such Controlling
Class Certificateholder, as applicable) any Excluded Information (available to Privileged Persons through the Certificate Administrator’s
Website but not accessible to the Controlling Class Representative or such Controlling Class Certificateholder, as applicable,
through the Certificate Administrator’s Website because the Controlling Class Representative or such Controlling Class Certificateholder,
as applicable, is an Excluded Controlling Class Holder with respect to another Excluded Controlling Class Mortgage Loan) relating
to any Excluded Controlling Class Mortgage Loan with respect to which the Controlling Class Representative or such Controlling
Class Certificateholder, as applicable, is not a Borrower Party; provided that, in connection therewith, the Master Servicer
or Special Servicer may require a written confirmation executed by the requesting Person substantially in such form as may be
reasonably acceptable to the Master Servicer or Special Servicer, generally to the effect that such Person is the Controlling
Class Representative or a Controlling Class Certificateholder, will keep such Excluded Information confidential and is not a Borrower
Party, upon which the Master Servicer or Special Servicer may conclusively rely. In addition, the Master Servicer and the


 






    	-324- 



     


    

 


Special
Servicer shall be entitled to conclusively rely on delivery from the Controlling Class Representative or a Controlling Class Certificateholder,
as applicable, of an Investor Certification substantially in the form of Exhibit M-1C that such Controlling Class Representative
or Controlling Class Certificateholder is not an Excluded Controlling Class Holder with respect to a particular Mortgage Loan.
For the avoidance of doubt, the Special Servicer referenced in this Section 4.02(e) shall include any applicable Excluded
Mortgage Loan Special Servicer with respect to the related Excluded Special Servicer Mortgage Loan(s).


 


Section 4.03      
Compliance With Withholding Requirements.


 


(a)            
Notwithstanding any other provision of this Agreement, the Paying Agent shall comply with all federal withholding requirements
with respect to payments to Certificateholders of interest or original issue discount that the Paying Agent reasonably believes
are applicable under the Code. The consent of Certificateholders shall not be required for any such withholding. In the event
the Paying Agent or its agent withholds any amount from interest or original issue discount payments or advances thereof to any
Certificateholder pursuant to federal withholding requirements, the Paying Agent shall indicate the amount withheld to such Certificateholder.
Any amount so withheld shall be treated as having been distributed to such Certificateholder for all purposes of this Agreement.


 


(b)           
Each Certificate 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 Certificate 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 Code Sections 1471(b) or 1472(b), as applicable),
such recipient shall deliver to the Paying Agent, with a copy to each of the Trustee and the Certificate Administrator, at the
time or times prescribed by the Code and at such time or times reasonably requested by the Paying Agent or the Trustee, such documentation
prescribed by the Code (including as prescribed by Code Section 1471(b)(3)(C)(i)) and such additional documentation reasonably
requested by the Paying Agent, the Trustee or the Certificate Administrator to comply with their respective obligations under
FATCA, to determine that such recipient has complied with such recipient’s obligations under FATCA, or to determine the
amount to deduct and withhold from such payment. For these purposes, “FATCA” means Section 1471 through 1474
of the Code and any regulations or official interpretations thereof (including any revenue ruling, revenue procedure, notice or
similar guidance issued by the U.S. Internal Revenue Service thereunder as a precondition to relief or exemption from taxes under
such Sections, regulations and interpretations), any agreements entered into pursuant to Code Section 1471(b)(1), and including
any amendments made to FATCA after the date of this Agreement.

Section 4.04      
REMIC Compliance.


 


(a)            
The parties intend that each Trust REMIC shall constitute, and that the affairs of each Trust REMIC shall be conducted so as to
qualify it as, a “real estate mortgage investment conduit” as defined in, and in accordance with, the REMIC Provisions,
and the provisions hereof shall be interpreted consistently with this intention. In furtherance of such intention, the Certificate
Administrator shall, to the extent permitted by applicable law, act as agent, and is hereby appointed to act as agent, of each
Trust REMIC and shall on behalf of each Trust REMIC: (i) prepare, timely deliver to the Trustee for execution (and the Trustee
shall timely execute) and file, or cause to be prepared and filed, all required Tax Returns for each Trust REMIC, using a calendar
year as the taxable year for each Trust REMIC when and as required by the REMIC Provisions and other applicable federal, state
or local income tax laws; (ii) make an election, on behalf of each Trust REMIC, to be treated as a REMIC on IRS Form 1066
for its first taxable year ending December 31, 2017, in accordance with the REMIC Provisions; (iii) prepare and forward,
or cause to be prepared and forwarded, to the Certificateholders (other than the Holders of the Class S Certificates) and the
IRS and applicable state and local tax authorities all information reports as and when required to be provided to them in accordance
with the REMIC Provisions of the Code; (iv) if the filing or distribution of any documents of an administrative nature not
addressed in clauses (i) through (iii) of this Section 4.04(a) is then required by the REMIC Provisions
in order to maintain the status of each Trust REMIC as a REMIC or is otherwise required by the Code, prepare, sign and file or
distribute, or cause to be prepared and signed and filed or distributed, such documents with or to such Persons when and as required
by the REMIC Provisions or the Code or comparable provisions of state and local law; (v) obtain a taxpayer identification
number for the Upper-Tier REMIC and Lower-Tier REMIC on IRS Form SS-4, and, within thirty days of the Closing Date, furnish or
cause to be furnished to the IRS, on IRS Form 8811 or as otherwise may be required by the Code, the name, title and address
of the Person that the holders of the Certificates may contact for tax information relating thereto (and the Certificate Administrator
shall act as the representative of each Trust REMIC for this purpose), together with such additional information as may be required
by such IRS 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 Master Servicer or the
Certificate Administrator and necessary to make such filing); and (vi) maintain such records relating to each Trust REMIC
as may be necessary to prepare the foregoing returns, schedules, statements or information, such records, for federal income tax
purposes, to be maintained on a calendar year and on an accrual basis.


 


The
Holder of the largest Percentage Interest in the Class R Certificates shall be the tax matters person of each Trust REMIC
pursuant to Treasury Regulations Section 1.860F-4(d) and the Certificate Administrator shall be the “partnership representative”
of each Trust REMIC (within the meaning of Code Section 6223, to the extent such provision is applicable to the Trust REMICs).
If more than one Holder should hold an equal Percentage Interest in the Class R Certificates larger than that held by any
other Holder, the first such Holder to have acquired such Class R Certificates shall be such tax matters person. The Certificate
Administrator shall act as attorney-in-fact and agent for the tax matters person of each Trust REMIC, and each Holder of a Percentage
Interest in the Class R Certificates, by acceptance thereof, is deemed to have consented to the Certificate Administrator’s
appointment in such capacity and agrees to execute any documents required to give effect thereto, and any fees and expenses incurred
by the Certificate


 






    	-326- 



     


    

 


Administrator in connection with any audit or administrative or judicial proceeding shall be paid by the Trust
Fund. The Certificate Administrator shall make any elections allowed under the Code (i) to avoid the application of Section 6221
of the Code (or successor provision) to any Trust REMIC and (ii) to avoid payment by any Trust REMIC under Section 6225 of the
Code of any tax, penalty, interest or other amount imposed under the Code that would otherwise be imposed on any holder of any
residual interest of any Trust REMIC, past or present. Each Holder of a Percentage Interest in the Class R Certificates, by acceptance
thereof, is deemed to agree to any such elections and to the Certificate Administrator’s acting as “partnership representative”
of each Trust REMIC that can be designated under the Code.


 


The
Certificate Administrator shall not intentionally take any action or intentionally omit to take any action within its control
and the scope of its duties if, in taking or omitting to take such action, the Certificate Administrator knows that such action
or omission (as the case may be) would cause the termination of the REMIC status of a Trust REMIC or the imposition of tax
on a Trust REMIC (other than a tax on income expressly permitted or contemplated to be received by the terms of this Agreement).


 


Notwithstanding
any provision of this paragraph or the three preceding paragraphs to the contrary, the Certificate Administrator shall not be
required to take any action that the Certificate Administrator in good faith believes to be inconsistent with any other provision
of this Agreement, nor shall the Certificate Administrator be deemed in violation of this paragraph if it takes any action expressly
required or authorized by any other provision of this Agreement, and the Certificate Administrator shall have no responsibility
or liability with respect to any act or omission of the Depositor or the Master Servicer which does not enable the Certificate
Administrator to comply with any of clauses (i) through (vi) of the third preceding paragraph or which results in any action
contemplated by clauses (i) through (iii) of the next succeeding sentence. In this regard the Certificate Administrator shall
(i) not allow the occurrence of any “prohibited transactions” within the meaning of Code Section 860F(a),
unless the party seeking such action shall have delivered to the Certificate Administrator an Opinion of Counsel (at such party’s
expense) that such occurrence would not (a) result in a taxable gain, (b) otherwise subject a Trust REMIC to tax
(other than a tax at the highest marginal corporate tax rate on net income from foreclosure property), or (c) cause either
Trust REMIC to fail to qualify as a REMIC for federal income tax purposes; (ii) not allow a Trust REMIC to receive income
from the performance of services or from assets not permitted under the REMIC Provisions to be held by such Trust REMIC (provided,
however, that the receipt of any income expressly permitted or contemplated by the terms of this Agreement shall not be
deemed to violate this clause); and (iii) not permit the creation of any “interests,” within the meaning of the
REMIC Provisions, in the Upper-Tier REMIC other than the Regular Certificates and the Upper-Tier Residual Interest, or in the
Lower-Tier REMIC other than the Lower-Tier Regular Interests and the Lower-Tier Residual Interest. None of the Trustee, the Master
Servicer, the Special Servicer or the Depositor shall be responsible or liable for any failure by the Certificate Administrator
to comply with the provisions of this Section 4.04. The Depositor, the Master Servicer and the Special Servicer shall
cooperate in a timely manner with the Certificate Administrator in supplying any information within the Depositor’s, the
Master Servicer’s or the Special Servicer’s control (other than any confidential information) that is reasonably
necessary to enable the Certificate Administrator to perform its duties under this Section 4.04.


 






    	-327- 



     


    

 


(b)           
The following assumptions are to be used for purposes of determining the anticipated payments of principal and interest for calculating
the original yield to maturity and original issue discount with respect to the Regular Certificates: (i) each Mortgage Loan
will pay principal and interest in accordance with its terms and scheduled payments will be timely received on their Due Dates,
provided that the Mortgage Loans in the aggregate will prepay in accordance with the Prepayment Assumption; (ii) none
of the Master Servicer, the Special Servicer, the Depositor and the Class R Certificateholder will exercise the right described
in Section 9.01 of this Agreement to cause early termination of the Trust Fund; and (iii) no Mortgage Loan is
repurchased or substituted for by the applicable Mortgage Loan Seller pursuant to Article II of this Agreement.


 


Section 4.05      
Imposition of Tax on the Trust REMICs. In the event that any tax, including interest, penalties or assessments, additional
amounts or additions to tax, is imposed on a Trust REMIC, such tax shall be charged against amounts otherwise distributable with
respect to the Regular Certificates and the Class R Certificates; provided that any taxes imposed on any net income
from foreclosure property pursuant to Code Section 860G(d) or any similar tax imposed by a state or local jurisdiction
shall instead be treated as an expense of the related REO Property in determining Net REO Proceeds with respect to the REO Property
(and until such taxes are paid, the Special Servicer from time to time shall withdraw from the REO Account and transfer to the
Certificate Administrator for deposit into the Distribution Accounts amounts reasonably determined by the Certificate Administrator
to be necessary to pay such taxes, and the Certificate Administrator shall return to the Special Servicer the excess determined
by the Certificate Administrator from time to time of the amount in excess of the amount necessary to pay such taxes); provided
that any such tax imposed on net income from foreclosure property that exceeds the amount in any such reserve shall be retained
from Available Funds as provided in Section 3.06(a)(vii) of this Agreement and the next sentence. Except as provided
in the preceding sentence, the Certificate Administrator is hereby authorized to and shall retain or cause to be retained from
the Distribution Account in determining the amount of Available Funds sufficient funds to pay or provide for the payment of, and
to actually pay, such tax as is legally owed by a Trust REMIC (but such authorization shall not prevent the Certificate Administrator
from contesting, at the expense of the Trust Fund, any such tax in appropriate proceedings, and withholding payment of such tax,
if permitted by law, pending the outcome of such proceedings). The Certificate Administrator is hereby authorized to and shall
segregate or cause to be segregated, into a separate non-interest bearing account, (i) the net income from any “prohibited
transaction” under Code Section 860F(a) or (ii) the amount of any contribution to a Trust REMIC after the
Startup Day that is subject to tax under Code Section 860G(d) and use such income or amount, to the extent necessary, to
pay such tax (and return the balance thereof, if any, to the related Distribution Account). To the extent that any such tax is
paid to the IRS, the Certificate Administrator shall retain an equal amount from future amounts otherwise distributable to the
Holders of the Class R Certificates in respect of the related residual interest and shall distribute such retained amounts
to the Holders of Regular Certificates or to the Certificate Administrator in respect of the Lower-Tier Regular Interests until
they are fully reimbursed and then to the Holders of the Class R Certificates in respect of the related residual interest.
None of the Master Servicer, the Special Servicer, the Certificate Administrator or the Trustee shall be responsible for any taxes
imposed on a Trust REMIC except to the extent such tax is attributable to a breach of a representation or warranty of the Master
Servicer, the Special Servicer, the Certificate Administrator or the Trustee or an act or omission of the Master Servicer, the
Special Servicer, the Certificate Administrator or the Trustee in contravention of this Agreement in both cases,


 






    	-328- 



     


    

 


provided, further, that such breach, act or omission
could result in liability under Section 6.03, in the case of the Master Servicer or the Special Servicer, as applicable,
or Section 4.04 or Section 8.01, in the case of the Certificate Administrator or the Trustee. Notwithstanding
anything in this Agreement to the contrary, in each such case, the Master Servicer or the Special Servicer shall not be responsible
for the Certificate Administrator’s, the Authenticating Agent’s, the Certificate Registrar’s, the Paying Agent’s
or the Trustee’s breaches, acts or omissions, and the Trustee shall not be responsible for the breaches, acts or omissions
of the Certificate Administrator, the Master Servicer, the Special Servicer, the Authenticating Agent, the Certificate Registrar
or the Paying Agent, and the Certificate Administrator shall not be responsible for the breaches, acts or omissions of the Trustee,
the Master Servicer, the Special Servicer and, in each case if a different entity than the Certificate Administrator, the Authenticating
Agent, the Certificate Registrar or the Paying Agent.


 


Section 4.06      
Remittances; P&I Advances.


 


(a)            
On the Master Servicer Remittance Date immediately preceding each Distribution Date, the Master Servicer shall:


 


(i)         
remit to the Certificate Administrator for deposit in the Lower-Tier REMIC Distribution Account an amount equal to the Yield Maintenance
Charges applicable to the Mortgage Loans (but not a Companion Loan) received by the Master Servicer during the Collection Period
relating to such Distribution Date (or, in the case of an Outside Serviced Mortgage Loan, received by the Master Servicer as of
the close of business on the Business Day immediately preceding the applicable Master Servicer Remittance Date and not previously
so remitted to the Certificate Administrator);


 


(ii)           
remit to the Certificate Administrator for deposit in the Lower-Tier REMIC Distribution Account an amount equal to the Available
Funds applicable to the Mortgage Loans (other than the amounts referred to in clause (iv) below and clause (d)
of the definition of “Available Funds”);


 


(iii)           
remit to CREFC® the CREFC® Intellectual Property Royalty License Fee;


 


(iv)          
make a P&I Advance by remittance to the Certificate Administrator for deposit into the Lower-Tier REMIC Distribution Account,
in an amount equal to the sum of the Applicable Monthly Payments for each Mortgage Loan (including any REO Mortgage Loan and any
Mortgage Loan related to a Loan Combination, but not a Companion Loan) to the extent such amounts were not received by the Master
Servicer on such Mortgage Loan as of the close of business on the Determination Date (without regard to any grace period) in the
same month as (or, in the case of an Outside Serviced Mortgage Loan, was not received by the Master Servicer on such Mortgage
Loan as of the close of business on the Business Day immediately preceding) such Master Servicer Remittance Date), except that
the portion of such P&I Advance equal to the CREFC® Intellectual Property Royalty License Fee for each such
Mortgage Loan shall not be remitted to the Certificate Administrator but shall instead be remitted to CREFC® and
the portion of such P&I Advance equal to the Asset Representations Reviewer Ongoing Fee, the Operating Advisor Fee or the
Trustee/Certificate Administrator Fee shall, to the extent the subject fee


 






    	-329- 



     


    

 


remains unpaid to the applicable party hereunder, shall
be deposited in the Collection Account for payment to such party;


 


(v)           
remit to the Certificate Administrator, as compensation for it and the Trustee, the Trustee/Certificate Administrator Fee for
the related Distribution Date;


 


(vi)          
remit to the Certificate Administrator for deposit in the Excess Liquidation Proceeds Reserve Account an amount equal to the Excess
Liquidation Proceeds received during the related Collection Period (or, in the case of an Outside Serviced Mortgage Loan, received
by the Master Servicer as of the close of business on the Business Day immediately preceding the applicable Master Servicer Remittance
Date and not previously so remitted to the Certificate Administrator), if any; and


 


(vii)         
remit to the Certificate Administrator for deposit in the Excess Interest Distribution Account all Excess Interest for the related
Distribution Date then on deposit in the Collection Account after giving effect to withdrawals of funds pursuant to Section 3.06(a)(ii)
through Section 3.06(a)(ix) of this Agreement.


 


Neither
the Master Servicer nor the Trustee shall be required or permitted to make an advance for Balloon Payments, Default Interest,
Excess Interest or Yield Maintenance Charges, or delinquent Monthly Payments on the Companion Loans. The amount required to be
advanced in respect of delinquent payments of interest on any Mortgage Loan as to which an Appraisal Reduction Amount exists will
equal the product of (i) the amount otherwise required to be advanced by the Master Servicer with respect to delinquent payments
of interest without giving effect to such Appraisal Reduction Amounts, and (ii) a fraction, the numerator of which is the Stated
Principal Balance of such Mortgage Loan as of the last day of the related Collection Period, reduced by such Appraisal Reduction
Amount, and the denominator of which is the Stated Principal Balance of such Mortgage Loan as of the last day of the related Collection
Period. Appraisal Reduction Amounts shall not affect the principal portion of any P&I Advances.


 


Any
amount advanced by the Master Servicer pursuant to Section 4.06(a)(iv) of this Agreement shall constitute a P&I
Advance for all purposes of this Agreement and the Master Servicer shall be entitled to reimbursement (with interest at the Advance
Rate). The Special Servicer shall have no obligation to make any P&I Advance.


 


The
Certificate Administrator shall notify the Master Servicer and the Trustee by telephone if as of 3:00 p.m., New York City
time, on the Master Servicer Remittance Date, the Certificate Administrator has not received the amount of a required P&I
Advance hereunder. If as of 11:00 a.m., New York City time, on any Distribution Date the Master Servicer shall not have made
the P&I Advance required to have been made on the related Master Servicer Remittance Date pursuant to Section 4.06(a)(iv)
of this Agreement, the Certificate Administrator shall notify the Trustee and the Trustee shall no later than 1:00 p.m.,
New York City time, on such Business Day deposit into the Lower-Tier REMIC Distribution Account in immediately available funds
an amount equal to the P&I Advances otherwise required to have been made by the Master Servicer.


 


Neither
the Master Servicer nor the Trustee shall be obligated to make a P&I Advance as to any Monthly Payment on any date on which
a P&I Advance is otherwise required to be made by this Section 4.06 if the Master Servicer or the Trustee, as
applicable, or the Special


 






    	-330- 



     


    

 


Servicer determines that such Advance will be a Nonrecoverable Advance. The determination by any Person
with an obligation hereunder to make P&I Advances that it has made (or in the case of a determination by the Special Servicer,
that the Master Servicer or the Trustee has made) a Nonrecoverable Advance or the determination by the Special Servicer, the Master
Servicer or the Trustee that any proposed P&I Advance, if made, would constitute a Nonrecoverable Advance, shall be made by
such Person (i) in the case of the Master Servicer or the Special Servicer, in accordance with the Servicing Standard or
(ii) in the case of the Trustee, in its good faith business judgment, and shall be evidenced by an Officer’s Certificate
as set forth in Section 4.06(b). In connection with a determination by the Special Servicer, the Master Servicer or
the Trustee as to whether a P&I Advance previously made or to be made constitutes or would constitute a Nonrecoverable Advance:


 


(A)           
any such Person will be entitled to consider (among other things) the obligations of the Mortgagor under the terms of the
related Mortgage Loan or Serviced Loan Combination as it may have been modified, to consider (among other things) the related
Mortgaged Properties in their “as is” or then current conditions and occupancies, as modified by such party’s
assumptions regarding the possibility and effects of future adverse change with respect to such Mortgaged Properties, to estimate
and consider (among other things) future expenses and to estimate and consider (among other things) the timing of recoveries;


 


(B)           
any such Person may update or change its recoverability determinations at any time (but not reverse any other Person’s determination
that an Advance is a Nonrecoverable Advance) and may obtain at the expense of the Trust Fund any analysis, Appraisals or market
value estimates or other information for such purposes;


 


(C)           
the Special Servicer may, at its option, make a determination in accordance with the Servicing Standard that any proposed P&I
Advance, if made, would be a Nonrecoverable Advance or that any outstanding P&I Advance is a Nonrecoverable Advance and may
deliver to the Master Servicer, the Trustee and the Controlling Class Representative (prior to the occurrence and continuance
of a Consultation Termination Event) notice of such determination, which determination shall be conclusive and binding on the
Master Servicer and the Trustee;


 


(D)           
although the Special Servicer may determine whether a P&I Advance is a Nonrecoverable Advance, the Special Servicer will have
no right to (i) make an affirmative determination that any P&I Advance previously made or to be made (or contemplated to be
made) by the Master Servicer or the Trustee is, or would be, recoverable or (ii) reverse any determination that may have been
made by the Master Servicer or the Trustee or to prohibit the Master Servicer or the Trustee from making a determination that
a P&I Advance constitutes or would constitute a Nonrecoverable Advance; provided that this sentence will not be construed
to limit the Special Servicer’s right to make a determination that a P&I Advance to be made (or contemplated to be made)
would be, or a previously made Advance is, a Nonrecoverable Advance, as described in this Section 4.06;


 






    	-331- 



     


    

 


(E)            
any non-recoverability determination by the Master Servicer or the Special Servicer pursuant to this Section 4.06
with respect to the recoverability of P&I Advances shall be conclusive and binding on the Master Servicer (in the case of
such a determination by the Special Servicer) and the Trustee;


 


(F)            
the Master Servicer shall provide notice to the Trustee on or prior to the Master Servicer Remittance Date of any such non-recoverability
determination made by the Master Servicer on or prior to such date;


 


(G)           
the Trustee shall be entitled to rely, conclusively, on any determination by the Master Servicer or Special Servicer that a P&I
Advance, if made, would be a Nonrecoverable Advance; provided, however, that if the Master Servicer has failed to
make a P&I Advance for reasons other than a determination by the Master Servicer or Special Servicer that such Advance would
be a Nonrecoverable Advance, the Trustee shall make such advance within the time periods required by this Section 4.06
unless the Trustee, in its good faith business judgment, or the Special Servicer, in accordance with the Servicing Standard,
makes a determination prior to the times specified in this Section 4.06 that such advance would be a Nonrecoverable
Advance;


 


(H)           
the Special Servicer shall report, promptly upon making a determination contemplated in this paragraph, to the Master Servicer
the Special Servicer’s determination as to whether any P&I Advance made with respect to any previous Distribution Date
or required to be made with respect to a future Distribution Date with respect to any Specially Serviced Loan is a Nonrecoverable
P&I Advance, and the Master Servicer and the Trustee shall be entitled to conclusively rely on such determination; and


 


(I)              
notwithstanding the foregoing, the Trustee may conclusively rely upon any determination by the Master Servicer or the Special
Servicer that any P&I Advance would be recoverable (unless a non-recoverability determination has been made by the other servicer
in accordance with clause (E) above which is binding on the Trustee), and the Master Servicer may conclusively rely upon
any determination by the Special Servicer that any P&I Advance would be recoverable.


 


The
Master Servicer or the Trustee, as applicable, shall be entitled to the reimbursement of P&I Advances it makes (together with
interest thereon) to the extent permitted pursuant to Section 3.06(a)(ii) of this Agreement and each of the Master
Servicer and Special Servicer hereby covenants and agrees to promptly seek and effect the reimbursement of such Advances from
the related Mortgagors to the extent permitted by applicable law and the related Mortgage Loan.


 


Within
2 Business Days of making a P&I Advance on any Mortgage Loan that is part of a Loan Combination, the Master Servicer or the
Trustee, as applicable, shall provide written notice of the amount of such P&I Advance to (i) if such Mortgage Loan is part
of a Serviced Loan Combination, the related Other Servicer, Other Special Servicer and Other Trustee of each Other Securitization
Trust that holds a related Serviced Companion Loan or (ii) if such Mortgage Loan


 






    	-332- 



     


    

 


is part of an Outside Serviced Loan Combination,
the related Outside Servicer, Outside Special Servicer and Outside Trustee of the related Outside Securitization Trust.


 


With
respect to P&I Advances and each Outside Serviced Mortgage Loan, the Master Servicer and the Trustee shall be entitled to
rely on the “appraisal reduction amount” calculated by the related Outside Special Servicer or the related Outside
Servicer in accordance with the terms of the applicable Outside Servicing Agreement.


 


(b)           
The determination by the Master Servicer, the Trustee or the Special Servicer that a P&I Advance has become a Nonrecoverable
P&I Advance or that any proposed P&I Advance, if made pursuant to this Section 4.06 with respect to any Mortgage
Loan (or with respect to any successor REO Mortgage Loan with respect to any of the foregoing), would constitute a Nonrecoverable
P&I Advance, shall be evidenced by an Officer’s Certificate delivered on or prior to the next Master Servicer Remittance
Date to the Trustee (unless it is the Person making the determination), the Controlling Class Representative (prior to the occurrence
and continuance of a Consultation Termination Event), the holder of any related Pari Passu Companion Loan or its Companion Loan
Holder Representative (in the case of a Pari Passu Loan Combination), the Master Servicer (unless it is the Person making the
determination), the Special Servicer (unless it is the Person making the determination) and, if the Trustee is making the determination,
the Depositor, setting forth the basis for such determination, together with any other information that supports such determination
together with a copy of any Appraisal of the related Mortgaged Property or REO Property, as the case may be (which Appraisal shall
be an expense of the Trust, shall take into account any material change in circumstances of which such Person is aware or such
Person has received new information, either of which has a material effect on the value and shall have been conducted in accordance
with the standards of the Appraisal Institute within the twelve months preceding such determination of nonrecoverability), and
further accompanied by related Mortgagor operating statements and financial statements, budgets and rent rolls of the related
Mortgaged Property (to the extent available and/or in such Person’s possession) and any engineers’ reports, environmental
surveys or similar reports that such Person may have obtained and that support such determination. The Master Servicer and the
Special Servicer shall consider Unliquidated Advances with respect to prior P&I Advances for the purpose of nonrecoverability
determinations as if such amounts were unreimbursed P&I Advances.


 


(c)            
With respect to each Outside Serviced Mortgage Loan, if (1) the related Outside Servicer has determined that a proposed debt
service advance with respect to such Outside Serviced Mortgage Loan or a related Outside Serviced Companion Loan, if made,
would be, or any outstanding debt service advance previously made with respect to such Outside Serviced Companion Loan is, as
applicable, a “nonrecoverable advance,” and the related Outside Servicer has provided written notice of such determination
to the Master Servicer, or (2) if the Master Servicer or the Special Servicer has determined that a P&I Advance with
respect to the Outside Serviced Mortgage Loan related to such related Outside Serviced Companion Loan would be a Nonrecoverable
P&I Advance, then neither the Master Servicer nor the Trustee shall make any additional P&I Advance with respect to such
Outside Serviced Mortgage Loan until the Master Servicer or the Special Servicer, as applicable, has consulted with the related
Outside Servicer under the applicable Outside Servicing Agreement and they agree that circumstances with respect to such Mortgage
Loans have changed such that a proposed future debt service advance would not be a “nonrecoverable advance.” With
respect to each Outside Serviced Mortgage Loan, if the


 






    	-333- 



     


    

 


Master Servicer, the Special Servicer or the Trustee, as applicable, has
determined that a proposed P&I Advance if made, or any outstanding P&I Advance previously made, with respect to such mortgage
loan would be, or is, as applicable, a Nonrecoverable Advance, the Master Servicer or the Trustee, as applicable, shall provide
the related Outside Servicer written notice of such determination (including, without limitation, any such determination made
by the Special Servicer, to the extent the Master Servicer or the Trustee has received an Officer’s Certificate with respect
to such determination in accordance with Section 4.06(b)) within two (2) Business Days after such determination was made.


 


In
connection with each Outside Serviced Mortgage Loan, any determination by the Master Servicer, the Trustee or the Special Servicer
that any P&I Advance made or to be made with respect to such Outside Serviced Mortgage Loan (or any successor REO Mortgage
Loan with respect thereto) is or, if made, would be a Nonrecoverable P&I Advance may be made independently from any determinations
(or the absence of any determinations) made under the applicable Outside Servicing Agreement regarding nonrecoverability of debt
service advances on the related Outside Serviced Companion Loan.


 


(d)           
If the Trustee, the Master Servicer or the Special Servicer has received written notice from Moody’s, Fitch or KBRA to the
effect that continuation of the Master Servicer or the Special Servicer in such capacity would result in the downgrade, qualification
or withdrawal of any rating then assigned by Moody’s, Fitch or KBRA, as applicable, to any Class of Certificates and citing
servicing concerns with such Master Servicer or Special Servicer, as applicable, as the sole or material factor in such rating
action, and such notice is not rescinded within 60 days, then the Trustee, the Master Servicer or the Special Servicer, as
applicable, shall promptly notify the other such parties and the Certificate Administrator, and the Certificate Administrator
shall promptly notify the Serviced Companion Loan Holder and the applicable master servicer of any Serviced Companion Loan.


 


Section 4.07      
Grantor Trust Reporting.


 


(a)            
The Certificate Administrator shall maintain adequate books and records to account for the separate entitlements of the Grantor
Trust.


 


(b)           
The parties intend that the Grantor Trust shall be treated as a “grantor trust” under the Code, and the provisions
thereof shall be interpreted consistently with this intention. In furtherance of such intention, none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Administrator shall vary the assets of the Grantor Trust so as
to take advantage of market fluctuations or so as to improve the rate of return of the Grantor Trust Certificates, and shall otherwise
comply with Treasury Regulations Section 301.7701-4(c). The Certificate Administrator shall timely file or cause to be timely
filed with the IRS Form 1041, Form 1099 or such other form as may be applicable and shall furnish or cause to be furnished to
the Holders of the respective Classes of the Grantor Trust Certificates, their allocable share of income and expense with respect
to the Class S Specific Grantor Trust Assets and proceeds thereof as such amounts are received or accrue, as applicable.


 


(c)            
 (i) The Grantor Trust is a WHFIT that is a WHMT. The Certificate Administrator shall 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


 






    	-334- 



     


    

 


Certificate Administrator on a timely basis. With respect to the Class S Certificates, the Certificate Administrator is hereby
directed to assume that Hare & Co. is the only “middleman” as defined by the WHFIT Regulations unless it has actual
knowledge to the contrary or the Depositor provides the Certificate Administrator with the identity of any other “middlemen”.
The Certificate Administrator will not be liable for any tax reporting penalties that may arise under the WHFIT Regulations in
the event that the IRS makes a determination that is contrary to the first sentence of this paragraph.


 


(ii)            
The Certificate Administrator, in its discretion, shall report required WHFIT information using either the cash or accrual method,
except to the extent the WHFIT Regulations specifically require a different method. The Certificate Administrator shall be under
no obligation to determine whether any Certificateholder uses the cash or accrual method. The Certificate Administrator shall
make available (via the Certificate Administrator’s 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.


 


(iii)            
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 that is not in its
possession being provided to the Certificate Administrator or (ii) incomplete, inaccurate or untimely information being provided
to the Certificate Administrator. Each owner of a class of securities representing, in whole or in part, beneficial ownership
of an interest in a WHFIT, by acceptance of its interest in such class of securities, will be deemed to have agreed to provide
the Certificate Administrator with information regarding any sale of such securities, including the price, amount of proceeds
and date of sale. Absent receipt of information regarding any sale of Certificates, 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.


 


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


 


Section 4.08      
Calculations.


 


Provided
that the Certificate Administrator receives the necessary loan-level information from the Master Servicer and/or the Special Servicer,
the Certificate Administrator shall be responsible for performing all calculations necessary in connection with the actual and
deemed distributions to be made pursuant to Section 4.01, the preparation of the Distribution Date


 






    	-335- 



     


    

 


Statements pursuant
to Section 4.02(a) and the actual and deemed allocations of Realized Losses to be made pursuant to Section 4.01.
The Certificate Administrator shall calculate the Principal Distribution Amount and the Interest Distribution Amounts for each
Distribution Date and shall allocate such amounts among Certificateholders in accordance with this Agreement. Absent actual knowledge
of an error therein, the Certificate Administrator shall have no obligation to recompute, recalculate or otherwise verify any
loan-level information provided to it by the Master Servicer. The calculations by the Certificate Administrator contemplated by
this Section 4.08 shall, in the absence of manifest error, be deemed to be correct for all purposes hereunder.


 


Section 4.09      
Secure Data Room. (a)  Within 60 days of the Closing Date, the Certificate Administrator shall create a
Secure Data Room, and the Depositor shall, upon the earlier of (i) receipt of all the Mortgage Loan Sellers’ Diligence File
Certifications and (ii) the 120th day following the Closing Date (but, in any event, no earlier than the date on which the Depositor
has received a written notice from the Certificate Administrator that the Secure Data Room has been created), deliver to the Certificate
Administrator (but solely with respect to any Diligence File(s) received by the Depositor as to which it has received the related
Mortgage Loan Seller’s Diligence File Certification) an electronic copy of the Diligence Files for the Mortgage Loans that
have been uploaded by the Mortgage Loan Sellers to the Designated Site. After the 120th day following the Closing Date, the Depositor
may deliver any Mortgage Loan Seller’s Diligence Files to the Certificate Administrator if it has not previously delivered
such Mortgage Loan Seller’s Diligence Files to the Certificate Administrator. Upon receipt thereof, the Certificate Administrator
shall promptly upload the contents of each Diligence File to the Secure Data Room. Access to the Secure Data Room shall be granted
by the Certificate Administrator to (i) the Asset Representations Reviewer and (ii) any other Person at the direction
of the Depositor, in each case, upon the occurrence of an Affirmative Asset Review Vote and receipt by the Certificate Administrator
of a certification substantially in the form of Exhibit KK hereto. In no case whatsoever shall Certificateholders be permitted
to access the Secure Data Room. For the avoidance of doubt, the Certificate Administrator shall be under no obligation to post
any documents to the Secure Data Room other than the contents of the Diligence Files initially delivered to it by the Depositor
with respect to each Mortgage Loan Seller.


 


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


 






    	-336- 



     


    


 


covenant to access only the documents necessary to perform its duties and responsibilities under this Agreement.


 


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

V

compliance, with applicable laws, and may have such letters, numbers or other marks of identification and such legends or endorsements
placed thereon as may be required by law, or as may, consistently herewith, be determined by the officers executing such Certificates,
as evidenced by their execution thereof. The Public Certificates (other than the Class X-A and Class X-B Certificates) shall be

$1 in excess thereof. If the initial Certificate Balance or initial Notional Amount, as applicable, of any Class of Certificates
(exclusive of the Class S and Class R Certificates) does not equal an integral multiple of $1, then a single Certificate of such
Class may be issued in a minimum denomination of authorized initial principal balance or


 






    	-337- 



     


    

 


initial notional amount, as applicable,
that includes the excess of (i) the initial Certificate Balance or initial Notional Amount, as applicable, of such Class

countersigns the Certificate, the Certificate shall be valid nevertheless. A Certificate shall not be valid until an authorized
signatory of the Certificate Administrator (who may be the same officer who executed the Certificate) manually countersigns the
Certificate. The signature shall be conclusive evidence that the Certificate has been executed and countersigned under this Agreement.


 


Section 5.02      
Form and Registration.


 


(a)            
Each Class of Public Certificates shall be represented by a single, global certificate in definitive, fully registered form without

decreased by adjustments made on the records of the Certificate Registrar, as custodian for the Depository, as hereinafter provided.


 


(b)           
Unless and until Definitive Certificates are issued in respect of a Class of Global Certificates, beneficial ownership interests
in such Certificates will be maintained and transferred on the book-entry records of the Depository and Depository Participants,
and all references to actions by Holders of such Class of Certificates will refer to action taken by the Depository upon instructions
received from the related registered Holders of Certificates through the Depository Participants in accordance with the Depository’s
procedures and, except as otherwise set forth herein, all references herein to payments, notices, reports and statements to Holders
of such Class of Certificates will refer to payments, notices, reports and statements to the Depository or its nominee as the
registered Holder thereof, for distribution to the related registered Holders of Certificates through the Depository Participants
in accordance with the Depository’s procedures.


 


(c)            
No transfer of any Private Certificate shall be made unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under applicable state securities laws, or is made in a
transaction which does not require such registration or qualification. If a transfer is to be made in reliance upon an exemption
from the Securities Act, and under the applicable state securities laws, then:


 


(i)            
The Certificates of each Class of the Private Certificates (other than the Certificates constituting the RR Interest, the Class
S Certificates and the Class R Certificates) sold in offshore transactions in reliance on Regulation S under the Act shall

    	-338- 



     


    

 


without interest coupons, substantially
in the applicable form set forth as an exhibit hereto (each a “Temporary Regulation S Global Certificate”),
which shall be deposited on the Closing Date on behalf of the purchasers of the Private Certificates represented thereby with
the Certificate Registrar, at its principal trust office, as custodian, for the Depository, and registered in the name of the
Depository or the nominee of the Depository for the account of designated agents holding on behalf of Euroclear and/or Clearstream.
Prior to the expiration of the 40-day period commencing on the later of the commencement of the offering and the Closing Date
(the “Restricted Period”), beneficial interests in each Temporary Regulation S 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 of Private
Certificates (a “Regulation S Global Certificate”) in the applicable form set forth as an exhibit hereto in
accordance with the procedures set forth in Section 5.03(f) of this Agreement. 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.


 


On
the Closing Date, the Certificate Administrator shall execute, the Authenticating Agent shall authenticate, and the Certificate
Administrator shall deliver to the Certificate Registrar the Regulation S Global Certificates, which shall be held by the Certificate
Registrar for purposes of effecting the exchanges contemplated by the preceding paragraph. Citibank, N.A. is hereby initially
appointed the Authenticating Agent with the power to act, on the Trustee’s behalf, in the authentication and delivery of
the Certificates in connection with transfers and exchanges as herein provided. If Citibank, N.A. is removed as Certificate Administrator,
then Citibank, N.A. shall be terminated as Authenticating Agent. If the Authenticating Agent is terminated, the Certificate Administrator
(or, if the same entity is acting as both the Authenticating Agent and the Certificate Administrator and such entity is being
removed from both capacities, a successor Certificate Administrator) shall appoint a successor authenticating agent, which may
be the Certificate Administrator or an Affiliate thereof, in accordance with Section 5.09 of this Agreement.


 


(ii)           
The Certificates of each Class of Private Certificates (other than the Certificates constituting the RR Interest, the Class S
Certificates and the Class R Certificates) offered and sold to Qualified Institutional Buyers in reliance on Rule 144A
shall be represented by a single, global certificate in definitive, fully registered form without interest coupons, substantially
in the applicable form set forth as an exhibit hereto (each, a “Rule 144A Global Certificate”), which
shall be deposited with the Certificate


 






    	-339- 



     


    

 


Registrar or an agent of the Certificate Registrar, as custodian for the Depository, and
registered in the name of the Depository or a nominee of the Depository. The aggregate Certificate Balance of a Rule 144A
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.


 


(iii)          
The Certificates of each Class of Private Certificates offered and sold in the United States to investors that are Institutional
Accredited Investors that are not Qualified Institutional Buyers, the Certificates constituting the RR Interest (during the RR
Interest Transfer Restriction Period), the Class S Certificates and the Class R Certificates (collectively, the “Non-Book
Entry Certificates”) shall be in the form of Definitive Certificates, in each case substantially in the applicable form
set forth as an exhibit hereto, and shall be registered in the name of such investors or their nominees by the Certificate Registrar
who shall deliver the certificates for such Non-Book Entry Certificates to the respective beneficial owners or owners.


 


(d)           
Owners of beneficial interests in Global Certificates of any Class shall not be entitled to receive physical delivery of certificated
Certificates unless: (i) the Depository advises the Certificate Registrar in writing that the Depository is no longer willing
or able to discharge properly its responsibilities as depository with respect to the Global Certificates of such Class or ceases
to be a Clearing Agency, and the Certificate Administrator and the Depositor are unable to locate a qualified successor within
90 days of such notice; (ii) the Trustee has instituted or has been directed to institute any judicial proceeding to
enforce the rights of the Holders of such Class and the Trustee has been advised by counsel that in connection with such proceeding
it is necessary or appropriate for the Trustee to obtain possession of the Certificates of such Class; or (iii) in the case
of a Private Certificate, all of the applicable requirements of Section 5.03 of this Agreement are satisfied; provided,
however, that under no circumstances will certificated Private Certificates be issued to beneficial owners of a Temporary
Regulation S Global Certificate. Upon notice of the occurrence of any of the events described in clause (i) or (ii)
above with respect to any Certificates of a Class that are in the form of Global Certificates and upon surrender by the Depository
of any Global Certificate of such Class and receipt from the Depository of instructions for reregistration, the Certificate Registrar
shall issue Certificates of such Class in the form of Definitive Certificates (bearing, in the case of a Definitive Certificate
issued for a Rule 144A Global Certificate, the same legends regarding transfer restrictions borne by such Global Certificate),
and thereafter the Certificate Registrar shall recognize the holders of such Definitive Certificates as Certificateholders under
this Agreement.


 


(e)            
If any Certificate Owner wishes to transfer its interest in a Rule 144A Global Certificate to an Institutional Accredited
Investor that is not a Qualified Institutional Buyer, or wishes to transfer its interest in a Regulation S Global Certificate
to a “U.S. person” (as that term is defined in Rule 902(k) under the Securities Act) that is an Institutional
Accredited Investor but not a Qualified Institutional Buyer, then the transferee shall take delivery in the form of a Non-Book
Entry Certificate, subject to the restrictions on the transfer of such Non-Book Entry Certificate in Section 5.03(h)
of this Agreement. No such transfer shall be made and the Certificate Registrar shall not register any such transfer unless such
transfer complies with the provisions of Section 5.03(h) of this Agreement applicable to transfers of Non-Book Entry
Certificates. Upon acceptance for exchange or transfer of a beneficial interest in a Global Certificate for a Non-Book


 






    	-340- 



     


    

 


Entry Certificate,
as provided herein, the Certificate Registrar shall endorse on the schedule affixed to the related Global Certificate (or on a
continuation of such schedule affixed to such Global Certificate and made a part thereof) an appropriate notation evidencing the
date of such exchange or transfer and a decrease in the denomination of such Global Certificate equal to the denomination of such
Non-Book Entry Certificate issued in exchange therefor or upon transfer thereof.


 


(f)            
During the RR Interest Transfer Restriction Period, any Certificate constituting a portion of the RR Interest shall only be held
as a Definitive Certificate in the Retained Interest Safekeeping Account by the Certificate Administrator (and each Retaining
Party’s respective interest shall be tracked in the form of an entry in the Certificate Administrator’s trust accounting
system under the Retained Interest Safekeeping Account), for the benefit of the Holder of the related Certificate. The Certificate
Administrator shall hold each Certificate constituting the RR Interest in safekeeping and shall release the same only upon receipt
of a written direction signed by each of the Retaining Sponsor and the Holder of such Certificate, and in accordance with any
authentication procedures as may be utilized by the Certificate Administrator and in accordance with this Agreement. There shall
be, and hereby is, established by the Certificate Administrator an account which will be designated the “Retained Interest
Safekeeping Account” and into which each Certificate constituting the RR Interest shall be held and which shall be governed
by and subject to this Agreement. In addition, on and after the date hereof, the Certificate Administrator may establish any number
of subaccounts to the Retained Interest Safekeeping Account for each Retaining Party. Each Certificate constituting the RR Interest
to be delivered in physical form to the Certificate Administrator shall be delivered as set forth herein. Upon receipt by the
Certificate Administrator of any Certificate constituting a portion of the RR Interest in connection with the initial issuance
thereof and, for so long as the Certificates constituting the RR Interest are held in the Retained Interest Safekeeping Account
by the Certificate Administrator pursuant to this Agreement, upon any transfer or exchange pursuant to this Article V of
any Certificate constituting a portion of the RR Interest, the Certificate Administrator shall deliver to the related Retaining
Party a receipt in the form set forth in Exhibit MM. No amounts distributable with respect to any Certificate constituting
a portion of the RR Interest shall be remitted to the Retained Interest Safekeeping Account, but instead shall be remitted directly
to the applicable Retaining Party in accordance with written instructions provided separately on the Closing Date (and any updates
to such written instructions provided from time to time) by such Retaining Party to the Certificate Administrator. Under no circumstances
by virtue of safekeeping any Certificate constituting a portion of the RR Interest shall the Certificate Administrator be obligated
to bring legal action or institute proceedings against any Person on behalf of any Retaining Party. During the RR Interest Transfer
Restriction Period and for such longer time as the related Retaining Party may request, the Certificate Administrator shall hold
each individual Certificate constituting the RR Interest at the below location, or any other location; provided the Certificate
Administrator has given notice to the Depositor, the Retaining Sponsor and each Retaining Party of such new location:


 


Citibank,

The
Certificate Administrator shall make available to each Retaining Party its account information as mutually agreed upon by the
Certificate Administrator and each respective Retaining Party, and in accordance with the Certificate Administrator’s policies
and procedures. Any transfer of a Certificate evidencing the RR Interest shall be subject to this Article V. During the
RR Interest Transfer Restriction Period, unless the Retaining Sponsor and the Depositor otherwise consent in writing, the Certificate
Administrator shall not permit any Person to copy (other than for internal purposes), and shall not itself provide to any Person
copies of, the executed Certificates held by it in the Retained Interest Safekeeping Account.


 


(g)           
To the extent that the aggregate value and/or Certificate Balance of the RR Interest is in excess of the amount or percentage
of risk retention required pursuant to Regulation RR, such excess portion of the RR Interest shall nevertheless be deemed to be
subject to the requirements of Regulation RR and any Certificate evidencing such excess portion of the RR Interest shall be subject
to all of the provisions in this Agreement applicable to the RR Interest including, without limitation, the provisions of this
Article V.


 


Section 5.03      
Registration of Transfer and Exchange of Certificates.


 


(a)

of each Class of Private Certificates represented by a Temporary Regulation S Global Certificate, a Regulation S Global Certificate
and a Rule 144A Global Certificate and accepting Certificates for exchange and registration of transfer and (ii) transmitting

transferees, one or more new Certificates in authorized denominations, in like aggregate interest and of the same Class.

the Rule 144A Global Certificate deposited with the Certificate Registrar as custodian for the Depository wishes at any time
during the Restricted Period to exchange its interest in such Rule 144A Global Certificate for an interest in the Temporary
Regulation S Global Certificate of the same Class, or to transfer its interest in such Rule 144A Global Certificate to an
institution that is required to take delivery thereof in the form of an interest in the Temporary Regulation S Global Certificate

Certificate. Upon receipt by the Certificate
Registrar, as registrar, at its office designated in Section 5.11 of this Agreement, of (1) instructions given in
accordance with the Depository’s procedures from a Depository Participant directing the Certificate Registrar to credit,
or cause to be credited, a beneficial interest in the Temporary Regulation S Global Certificate in an amount equal to the beneficial
interest in the Rule 144A Global Certificate to be exchanged, (2) a written order given in accordance with the Depository’s
procedures containing information regarding the Euroclear or Clearstream account to be credited with such increase and the name

to be increased, the Certificate Balance of the Temporary Regulation S Global Certificate by the aggregate Certificate Balance
of the beneficial interest in the Rule 144A Global Certificate to be exchanged, to credit or cause to be credited to the
account of the Person specified in such instructions (who shall be the agent member of Euroclear or Clearstream, or both) a beneficial
interest in the Temporary Regulation S Global Certificate equal to the reduction in the Certificate Balance of the Rule 144A
Global Certificate, and to debit, or cause to be debited, from the account of the Person making such exchange or transfer the
beneficial interest in the Rule 144A Global Certificate that is being exchanged or transferred.


 


(d)           
Rule 144A Global Certificate to Regulation S Global Certificate. If a holder of a beneficial interest in the Rule 144A
Global Certificate deposited with the Certificate Registrar as custodian for the Depository wishes at any time following the Restricted
Period to exchange its interest in such Rule 144A Global Certificate for an interest in the Regulation S Global Certificate
of the same Class, or to transfer its interest in such Rule 144A Global Certificate to an institution that is required to
take delivery thereof in the form of an interest in a Regulation S Global Certificate, such holder may, subject to the rules and
procedures of the Depository, exchange, or cause the exchange of, such interest for an equivalent beneficial interest in such
Regulation S Global Certificate. Upon receipt by the Certificate Registrar, as registrar, at its office designated in Section 5.11
of this Agreement, of (1) instructions given in accordance with the Depository’s procedures from a Depository Participant

(e)            
Temporary Regulation S Global Certificate or Regulation S Global Certificate to Rule 144A Global Certificate. If a
holder of a beneficial interest in a Temporary Regulation S Global Certificate or Regulation S Global Certificate deposited with
the Certificate Registrar as custodian for the Depository wishes at any time to exchange its interest in such Temporary Regulation
S Global Certificate or Regulation S Global Certificate for an interest in the Rule 144A Global Certificate of the same Class,
or to transfer its interest in such Temporary Regulation S Global Certificate or Regulation S Global Certificate to a Person who
is required to take delivery thereof in the form of an interest in the Rule 144A Global Certificate, such holder may, subject
to the rules and procedures of Euroclear or Clearstream, as the case may be, and the Depository, exchange or cause the exchange
of such interest for an equivalent beneficial interest in the Rule 144A Global Certificate of the same Class. Upon receipt
by the Certificate Registrar, as registrar, at its office designated in Section 5.11 of this Agreement, of (1) instructions
from Euroclear or Clearstream, if applicable, and the Depository, directing the Certificate Registrar, as registrar, to credit
or cause to be credited a beneficial interest in the Rule 144A Global Certificate equal to the beneficial interest in the
Temporary Regulation S Global Certificate or Regulation S Global Certificate to be exchanged, such instructions to contain information

interest in the Regulation S Global Certificate, information regarding the participant account of the Depository to be debited
with such decrease and (3) with respect to a transfer of an interest in the Temporary Regulation S Global Certificate (but not
the Regulation S Global Certificate) for an interest in the Rule 144A Global Certificate at any time during the Restricted
Period, a certificate in the form of Exhibit G to this Agreement given by the holder of such beneficial interest and
stating that the Person transferring such interest in the Temporary Regulation S Global Certificate reasonably believes that the
Person acquiring such interest in the Rule 144A Global Certificate is a Qualified Institutional Buyer and is obtaining such
beneficial interest in a transaction meeting the requirements of Rule 144A, then the Certificate Registrar shall instruct
the Depository to reduce, or cause to be reduced, the Certificate Balance of the Temporary Regulation S Global Certificate or
Regulation S Global Certificate and to increase, or cause to be increased, the Certificate Balance of the Rule 144A Global
Certificate by the aggregate Certificate Balance of the beneficial interest in the Temporary Regulation S Global Certificate or
Regulation S Global Certificate to be exchanged, and the Certificate Registrar shall instruct the Depository, concurrently with
such reduction, to credit, or cause to be credited, to the account of the Person specified in such instructions, a beneficial
interest in the Rule 144A Global Certificate equal to the reduction in the Certificate Balance of the Temporary Regulation
S Global Certificate or Regulation S Global Certificate and to debit, or cause to be debited, from the account of the Person making
such transfer the beneficial interest in the Temporary Regulation S Global Certificate or Regulation S Global Certificate that
is being transferred.


 


(f)            
Temporary Regulation S Global Certificate to Regulation S Global Certificate. Interests in a Temporary Regulation S Global
Certificate as to which the Certificate Registrar has received from Euroclear or Clearstream, as the case may be, a certificate
(a “Non-U.S. Beneficial Ownership Certification”) to the effect that Euroclear or Clearstream, as applicable,
has received a certificate substantially in the form of Exhibit H to this Agreement from the holder of a beneficial
interest in such Temporary Regulation S Global Certificate, shall be exchanged after the Restricted Period, for interests in the
Regulation S Global Certificate of the same Class of Private Certificates. The Certificate Registrar shall effect such exchange
by delivering to the Depository for credit to the respective accounts of such holders, a duly executed


 






    	-344- 



     


    

 


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 that is a Private Certificate
(other than any Certificate constituting a portion of the RR Interest during the RR Interest Transfer Restriction Period, a Class
S Certificate or 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 an institution
that is entitled to take delivery thereof in the form of an interest in a Global Certificate, such holder may, subject to the
rules and procedures of Euroclear or Clearstream, if applicable, and the Depository, cause the exchange of all or part of such
Non-Book Entry Certificate for an equivalent beneficial interest in the appropriate Global Certificate of the same Class. Upon
receipt by the Certificate Registrar, as registrar, at its office designated in Section 5.11 of this Agreement, 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 I
to this Agreement (in the event that the applicable Global Certificate is the Temporary Regulation S Global Certificate),
in the form of Exhibit J to this Agreement (in the event that the applicable Global Certificate is the Regulation
S Global Certificate) or in the form of Exhibit K to this Agreement (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, and shall, if applicable, direct the Certificate Administrator to 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 institution 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.


 






    	-345- 



     


    

 


(h)           
Exchanges of Non-Book Entry Certificates. If a holder of a Rule 144A Global Certificate, Regulation S Global Certificate
or Non-Book Entry Certificate (other than a Public Certificate) wishes at any time to transfer its interest in such Rule 144A
Global Certificate, Regulation S Global Certificate or Non-Book Entry Certificate to a Person who is required to take delivery
thereof in the form of a Non-Book Entry Certificate, then (except in connection with the transfer or deemed transfer thereof by
the Depositor, an Initial Purchaser or, if occurring on the Closing Date, the Retaining Sponsor) the Certificate Registrar shall
refuse to register such transfer unless it receives (and upon receipt, may conclusively rely upon): (i) a certificate from
the proposed transferor substantially in the form attached as Exhibit L-2B to this Agreement, (ii) an investment representation
letter from the proposed transferee substantially in the form attached as Exhibit L-4 to this Agreement; and (iii) if
required by the Certificate Registrar, an opinion of counsel satisfactory to the Certificate Registrar to the effect that such
transfer shall be made without registration under the Securities Act, together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such transfer and/or the proposed transferee on which
such opinion of counsel is based (such opinion of counsel shall not be an expense of the Trust or of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator, the Trustee or the Certificate Registrar
in their respective capacities as such).


 


(i)             
Transfers of Certificates Constituting the RR Interest. At all times during the RR Interest Transfer Restriction Period,
if a transfer of any Certificate constituting 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 L-5, which such certification
must be countersigned by the applicable Retaining Party and the Retaining Sponsor (if different than the Retaining Party), and
(ii) a certification from the Certificateholder desiring to effect such transfer substantially in the form attached hereto as
Exhibit L-6, which such certification must be countersigned by the applicable Retaining Party (if different than the transferor)
and the Retaining Sponsor (if different than the Retaining Party). Upon receipt of the foregoing certifications, the Certificate
Registrar shall, subject to Section 5.02(f), Section 5.03(a), Section 5.03(h), the following provisions of
this Section 5.03(i), and Section 5.03(n), reflect such Certificate constituting the RR Interest in the name of
the prospective Transferee. In no event shall a Certificate evidencing the RR Interest be held as a Global Certificate during
the RR Interest Transfer Restriction Period. In connection with each transfer of a Certificate constituting a portion of the RR
Interest after the Closing Date, the transferor of such Certificate shall pay to the Certificate Administrator a transfer fee
of $5,000 (together with any other expenses related to such transfer (including fees charged by the Depository, if applicable))
and such fee and expenses must be received by the Certificate Administrator prior to the transfer date or the Certificate Administrator
shall not be required to complete the requested transfer.


 


(j)             
Other Exchanges. In the event that a Global Certificate is exchanged for a Definitive Certificate (other than as otherwise
set forth in Section 5.02(d) of this Agreement), such Certificates may be exchanged only in accordance with such procedures
as are substantially consistent with the provisions of clauses (c) through (f), (h) and (i) 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.


 






    	-346- 



     


    

 


(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 Private 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 Private 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, Regulation RR 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)           
No Class S Certificate or Class R Certificate may be purchased by or transferred to any prospective purchaser or transferee
that is or will be (i) an employee benefit plan or other plan subject to the fiduciary responsibility or prohibited transaction
provisions of ERISA or Code Section 4975 (each, a “Plan”), or (ii) any entity or collective investment
fund the assets of which are considered Plan assets under U.S. Department of Labor Reg. Section 2510.3-101, as modified by Section
3(42) of ERISA, or Similar Law (as defined below), an insurance company that is using the assets of separate accounts or general
accounts which include Plan assets (or which are deemed to include assets of Plans) or other Person acting on behalf of any such
Plan or using the assets of a Plan (each, a “Plan Investor”) to purchase such Certificate. In addition, no
ERISA Restricted Certificate or interest therein may be purchased by or transferred to any prospective purchaser or transferee
that is or will be a Plan or Plan Investor, unless (i) such purchaser or transferee is an insurance company, (ii) the source of
funds used to acquire or hold such ERISA Restricted Certificate or interest therein is an “insurance company general account,”
as such term is defined in PTCE 95-60, and (iii) the conditions in Sections I and III of PTCE 95-60 have been satisfied.
Furthermore, no ERISA Restricted Certificate, Class S Certificate or Class R Certificate or interest therein may be purchased
by or transferred to any prospective purchaser or transferee that is or will be 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 fiduciary
responsibility or prohibited transaction provisions of ERISA or Code Section 4975 (“Similar Law”), or to any
Person acting on behalf of any such plan or using the assets of such plan to acquire such Certificate or interest therein unless,
in the case of an ERISA Restricted Certificate, its acquisition, holding and disposition of such Certificate or an interest therein
would not constitute or otherwise result in a non-exempt violation of Similar Law. Except in connection with the transfer or deemed
transfer thereof by the Depositor, an Initial Purchaser or, if occurring on the Closing Date, the Retaining Sponsor, each prospective
transferee of an ERISA Restricted Certificate, a Class S Certificate or a Class R Certificate in the form of a Non-Book Entry


 






    	-347- 



     


    

 


Certificate shall deliver to the transferor, the Depositor, the Certificate Registrar, the Certificate Administrator and the Trustee
representation letters, substantially in the form of Exhibit L-3 and Exhibit L-4 to this Agreement. Each beneficial
owner of a Certificate (other than a Class S or Class R Certificate) or any interest therein will be deemed to have represented,
by virtue of its acquisition or holding of such Certificate or interest therein, that either (i) it is not a Plan or Plan
Investor, (ii) except in the case of an ERISA Restricted Certificate, it has acquired and is holding the Certificates in
reliance on the Underwriter Exemption, and that it understands that there are certain conditions to the availability of the Underwriter

transferee shall deliver to the Certificate Registrar and to the proposed transferor, an affidavit in substantially the form attached
as Exhibit L-1 to this Agreement (a “Transferee Affidavit”) of the proposed transferee (A) that

false.


 


(iii)

to such proposed transferee shall be effected and such proposed Transfer shall not be registered on the Certificate Register;
provided, however, the Certificate Registrar shall not be required to conduct any independent investigation to determine
whether a proposed transferee is a Permitted Transferee. Upon notice to the Certificate Registrar that there has occurred a Transfer

as may be required by it to save it harmless, then, in the absence of actual notice that such Certificate has been acquired by
a bona fide purchaser, the Certificate Registrar shall direct the Certificate Administrator to 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

which shall be acceptable to the Depositor, and shall mail notice of such appointment to all Certificateholders. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and
responsibilities of its predecessor hereunder, with like effect as if originally named as Authenticating Agent herein. No successor

by entering into a Custodial Agreement (in the event the Certificate Administrator is not the Custodian) that is consistent in
all material respects with this Agreement. The Certificate Administrator shall give prompt written notice to the Depositor of
any appointment of a Custodian. The Certificate Administrator agrees to comply with the terms of each Custodial Agreement, to
enforce the terms and provisions thereof against the Custodian for the benefit of the Certificateholders and Serviced Companion

coverage afforded thereunder extends to the Custodian. In addition, the Custodian shall keep in force during the term of this
Agreement a policy or policies of insurance covering loss occasioned by the errors and omissions of its officers and employees
in connection with its obligations hereunder in the form and amount that are customary for securitizations similar to the securitization
evidenced by this Agreement, with the Certificate Administrator named as loss payee. All fidelity bonds and policies of errors
and omissions insurance obtained under this Section 5.10 shall be issued by a Qualified Insurer, or by any other insurer
with respect to which the Rating Agencies have provided to the Trustee a Rating Agency Confirmation. The Custodian shall be subject
to the same obligations and standard of care as would be imposed on the Certificate Administrator hereunder in connection with
the retention of Mortgage Files directly by the Certificate Administrator. Upon termination or resignation of any Custodian appointed
by it, the Certificate Administrator may appoint another Custodian meeting the foregoing requirements. The appointment of a Custodian
shall not relieve the Certificate Administrator from any of its obligations hereunder, and the Certificate Administrator shall
remain responsible for all acts and omissions of the Custodian. In the event the Certificate Administrator is the Custodian, the
Custodian may self-insure.


 


Section 5.11

in the manner set forth on the ballot, unless a specific manner is otherwise provided herein. Holders may only vote in accordance

to vote. Once a Holder has cast its vote, the vote may be changed or retracted on or before the vote deadline. Any changes or
retractions shall be communicated by the Certificateholder to the Certificate Administrator in writing on a ballot. After the
vote deadline has passed, votes may not be changed or retracted by any Holder unless the Holder wishing to change or retract its

subject to a vote without taking into consideration the votes cast by any other Holder. Transferees or purchasers of any Class
of Certificates are subject to and shall be bound by all votes of Holders initiated or conducted prior to its acquisition of such

shall use its reasonable efforts to resolve any illegible or incomplete ballots received prior to the voting deadline. Illegible
or incomplete ballots that are received on the voting deadline or that cannot be resolved by the voting deadline shall not be
counted. Promptly after the votes are tabulated, the Certificate Administrator shall prepare a notice announcing the results of
the vote. Such notice shall include the percentage of Voting Rights in favor of the proposition, the percentage against the proposition
and the percentage abstaining. In addition, the notice will announce whether the proposition has been adopted by Certificateholders.
The notice shall be distributed in accordance with the methods described in Section 5.12(a) above. The Certificate Administrator
shall also include such notice on the Form 10-D prepared in connection with the distribution period that corresponds with the
date such notice is distributed. All vote tabulations shall be final and the Certificate Administrator shall not, absent manifest
error, re-tabulate the votes or conduct a new vote for the same proposition.


 


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


 


(e)            
If any party to this Agreement believes a vote of Certificateholders is needed for some matter related to the administration of
the Trust that is not specifically contemplated herein, such party may request the Certificate Administrator to conduct a vote
and the Certificate Administrator will conduct the requested vote in accordance with these procedures.


 






    	-356- 



     


    

 


Unless specifically provided
herein, all such votes require a majority of Certificateholders to carry a proposition.

(including, without limitation, reasonable attorneys’ fees and expenses) incurred by such parties (i) in connection
with any willful misconduct, bad faith, fraud and/or negligence in the performance of duties of the Depositor or by reason of

Section 6.02      
Merger or Consolidation of the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer. Subject
to the following paragraph, each of the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations
Reviewer shall keep in full effect its existence, rights and good standing as a national banking association, a corporation or
a limited liability company, as applicable, under the laws of the state of its organization and shall not jeopardize its ability

    	-357- 



     


    

 


the Certificates or any of the Mortgage
Loans and to perform its respective duties under this Agreement.


 


Each
of the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer may be merged or consolidated
with or into any Person, or transfer all or substantially all of its assets (which may be limited to all or substantially all
of its assets related to commercial mortgage loan servicing or, in the case of the Operating Advisor, may be limited to all or
substantially all of its assets related to acting as a trust advisor or operating advisor for commercial mortgage securitizations)
to any Person, in which case any Person resulting from any merger or consolidation to which it shall be a party, or any Person
succeeding to its business, shall be the successor of the Master Servicer, the Special Servicer, the Operating Advisor or the
Asset Representations Reviewer, as applicable, hereunder, and shall be deemed to have assumed all of the liabilities of the Master
Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, as applicable, hereunder, if each
of the Rating Agencies has provided a Rating Agency Confirmation; provided that if the Master Servicer, the Special Servicer,
the Operating Advisor or the Asset Representations Reviewer enters into a merger and the Master Servicer, the Special Servicer,
the Operating Advisor or the Asset Representations Reviewer, as applicable, is the surviving entity under applicable law, then
the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, as applicable, shall not,
as a result of the merger, be required to provide a Rating Agency Confirmation.


 


Section 6.03      
Limitation on Liability of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer and Others. None of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset
Representations Reviewer or any of the directors, members, managers, officers, employees or agents of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer shall be under any liability to the
Trust Fund, the Certificateholders, the Companion Loan Holders or any other Person for any action taken, or for refraining from
the taking of any action, in good faith pursuant to this Agreement, or for errors in judgment. However, none of the Depositor,
the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer or any such Person shall
be protected against any liability which would otherwise be imposed by reason of (i) any breach of warranty or representation
by such respective party in this Agreement or (ii) any willful misconduct, bad faith, fraud or negligence on the part of
such respective party in the performance of its obligations and duties hereunder or by reason of negligent disregard on the part
of such respective party of its obligations or duties hereunder. The Depositor, the Master Servicer, the Special Servicer, the
Operating Advisor, the Asset Representations Reviewer and any director, member, manager, officer, employee or agent of the Depositor,
the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer may rely in good faith
on any document of any kind which, prima facie, is properly executed and submitted by any appropriate Person respecting any matters
arising hereunder. The Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer and any director, member, manager, officer, employee or agent of the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor or the Asset Representations Reviewer shall be indemnified and held harmless by the Trust Fund (which indemnification
amounts shall be payable out of the Collection Account or the applicable Loan Combination Custodial Account if and to the extent
with respect to a Serviced Loan Combination and then out of the Collection Account, provided that, to the extent


 






    	-358- 



     


    

 


that the amount relates to a Serviced Loan Combination,
is required under the related Co-Lender Agreement to be borne by the holder of a related Serviced Companion Loan and is paid from
the Collection Account because funds on deposit in the applicable Loan Combination Custodial Account are insufficient to pay such
indemnification, then the Master Servicer shall from time to time thereafter use amounts otherwise payable to the holder of such
Serviced Companion Loan to deposit into the Collection Account the amount so paid from the Collection Account) against any loss,
liability, penalty, fine, forfeiture, claim, judgment or expense (including reasonable legal fees and expenses) incurred
in connection with, or relating to, this Agreement or the Certificates, other than any loss, liability, penalty, fine, forfeiture,
claim, judgment or expense (including reasonable legal fees and expenses) (i) incurred by reason of willful misconduct, bad
faith, fraud or negligence in the performance of its obligations or duties hereunder or by reason of negligent disregard of its
obligations or duties hereunder, in each case by the Person being indemnified, (ii) with respect to any such party, resulting
from the breach by such party of any of its representations or warranties contained herein, (iii) specifically required to
be borne by the party seeking indemnification without right of reimbursement pursuant to the terms hereof or (iv) which constitutes
an Advance that is otherwise reimbursable hereunder. None of the Depositor, the Master Servicer, the Special Servicer, the Operating
Advisor or the Asset Representations Reviewer shall be under any obligation to appear in, prosecute or defend any legal action
unless such action is related to its respective duties under this Agreement and in its opinion does not expose it to any expense
or liability for which reimbursement is not reasonably assured, and neither the Operating Advisor nor the Asset Representations
Reviewer may prosecute on behalf of the Trust or in the interests of the Certificateholders any legal action related to its duties
under this Agreement under any circumstances; provided, however, that each of the Depositor, the Master Servicer
and the Special Servicer may in its discretion undertake any such action related to its obligations hereunder which it may deem
necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto and the interests of the
Certificateholders hereunder. In such event, the reasonable legal expenses and costs of such action and any liability resulting
therefrom shall be expenses, costs and liabilities of the Trust Fund (payable out of the Collection Account or the applicable
Loan Combination Custodial Account if and to the extent with respect to a Serviced Loan Combination and then out of the Collection
Account, provided that to the extent that the amount relates to a Serviced Loan Combination, is required under the related Co-Lender
Agreement to be borne by the holder of a related Serviced Companion Loan and is paid from the Collection Account because funds
on deposit in the applicable Loan Combination Custodial Account are insufficient to pay such indemnification, then the Master
Servicer shall from time to time thereafter use amounts otherwise payable to the holder of such Serviced Companion Loan to deposit
into the Collection Account the amount so paid from the Collection Account), and the Depositor, the Master Servicer and the Special
Servicer shall be entitled to be reimbursed therefor from the Collection Account or the applicable Loan Combination Custodial
Account, as applicable, as provided in Section 3.06 and Section 3.06A of this Agreement.


 


Each
of the related Outside Servicer, the related Outside Special Servicer or the related Outside Trustee, as applicable, shall be
entitled to reimbursement out of general collections in the Collection Account for the Trust’s pro rata share of
any fees, costs or expenses incurred in connection with the servicing and administration of an Outside Serviced Loan Combination
as to which the securitization trust created under the applicable Outside Servicing Agreement or any of the parties thereto are
entitled to be reimbursed pursuant to the terms of the applicable Outside Servicing Agreement and the related Co-Lender Agreement
(to the extent amounts on deposit in


 






    	-359- 



     


    

 


the related “Serviced Whole Loan Custodial Account” or “Loan Combination
Custodial Account” (as each such term or any analogous term is defined in the applicable Outside Servicing Agreement) are
insufficient for reimbursement of such amounts).


 


Section 6.04      
Limitation on Resignation of the Master Servicer, the Special Servicer or the Operating Advisor.


 


(a)            
Each of the Master Servicer and the Special Servicer may resign, assign its respective rights and delegate its respective
duties and obligations under this Agreement by giving written notice thereof to the other such party, the Trustee, the Certificate
Administrator (who shall post such notice to the Certificate Administrator’s Website for review by Privileged Persons in
accordance with Section 4.02(a)), the Depositor, the Operating Advisor, the Asset Representations Reviewer, the Serviced
Companion Loan Holders and, for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section 12.13
of this Agreement, the Rule 17g-5 Information Provider; provided that, with respect to any of the Master Servicer or the
Special Servicer: (i) the successor accepting such assignment and delegation (A) shall be an established mortgage finance
entity, bank or other entity regularly engaged in the servicing of commercial mortgage loans, organized and doing business under
the laws of any state of the United States, the District of Columbia or the United States, authorized under such laws to perform
the duties of a servicer of mortgage loans or a Person resulting from a merger, consolidation or succession that is permitted
under Section 6.02 of this Agreement and, in the case of a Serviced Loan Combination, under the related Co-Lender
Agreement and (B) shall execute and deliver to the Trustee and the Certificate Administrator an agreement which contains
an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed
or observed by the Master Servicer or the Special Servicer, as the case may be, under this Agreement from and after the date of
such agreement; (ii) each Rating Agency has delivered to the Trustee a Rating Agency Confirmation; (iii) the Master
Servicer or the Special Servicer 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 6.04; (iv) the rate at which the Servicing Fee or Special
Servicing Compensation, as applicable (or any component thereof) is calculated shall not exceed the rate then in effect;
(v) for so long as no Control Termination Event has occurred and is continuing, the successor Special Servicer is acceptable
to the Controlling Class Representative (and, if a Serviced Outside Controlled Loan Combination is affected, the successor Special
Servicer is acceptable to the related Outside Controlling Note Holder); (vi) the resigning Master Servicer or Special Servicer,
as applicable, shall be responsible for the reasonable costs and expenses of each other party hereto, the Trust and the Rating
Agencies in connection with such transfer; (vii) none of the Operating Advisor, the Asset Representations Reviewer nor any of
their Affiliates shall in any event be appointed as successor Master Servicer or Special Servicer; and (viii) neither the Third
Party Purchaser nor any of its Risk Retention Affiliates shall in any event be appointed as successor Master Servicer. Upon acceptance
of such assignment and delegation, the purchaser or transferee shall be the successor Master Servicer or Special Servicer, as
applicable, hereunder.


 


(b)           
Except as otherwise provided in Section 3.34, this Section 6.04 and Section 6.08(j), the Master Servicer
and the Special Servicer shall not resign from their respective obligations and duties hereby imposed on them except upon determination
that such duties hereunder are no longer permissible under applicable law; provided that, on and after the time the Trustee
receives notice of resignation by the Master Servicer or the Special Servicer upon


 






    	-360- 



     


    

 


determination that such duties hereunder are
no longer permissible under applicable law, the Trustee (solely with respect to the Master Servicer or the Special Servicer) shall,
subject to the terms and provisions of Section 7.02 of this Agreement as if the resigning party was a Terminated Party,
be its successor in all respects in its capacity as Master Servicer or Special Servicer, as applicable, as though the Master Servicer
or the Special Servicer, as the case may be, had received a notice of termination. Any such determination permitting the resignation
of the Master Servicer or the Special Servicer, as applicable, shall be evidenced by an Opinion of Counsel (obtained at the resigning
Master Servicer’s or Special Servicer’s expense) to such effect delivered to the Trustee and the Certificate Administrator.


 


Except
as provided in the immediately preceding paragraph, no resignation or removal of the Master Servicer, the Special Servicer as
contemplated herein shall become effective until the Trustee (solely with respect to the Master Servicer or the Special Servicer)
or a successor Master Servicer, Special Servicer shall have assumed the Master Servicer’s or the Special Servicer’s,
as applicable, responsibilities, duties, liabilities and obligations hereunder. Notwithstanding anything to the contrary herein,
none of the Operating Advisor, the Asset Representations Reviewer nor any of their Affiliates may be appointed as successor Master
Servicer or Special Servicer. If no successor Master Servicer or Special Servicer can be obtained to perform such obligations
for the same compensation to which the terminated Master Servicer or Special Servicer would have been entitled, additional amounts
payable to such successor Master Servicer or Special Servicer shall be payable out of the Trust; provided that, for so
long as no Consultation Termination Event has occurred and is continuing, the Trustee shall consult with the Controlling Class
Representative prior to the appointment of a successor Master Servicer, Special Servicer or Operating Advisor at a servicing or
operating advisor compensation in excess of that permitted to the terminated Master Servicer, Special Servicer or Operating Advisor,
as applicable.


 


If
the Trustee or an Affiliate acts pursuant to this Section 6.04 as successor to the resigning Master Servicer, it may
reduce the Excess Servicing Fee Rate to the extent that the Trustee’s or such Affiliate’s compensation as successor
Master Servicer would otherwise be below the market rate servicing compensation. If the Trustee elects to appoint a successor
to the resigning Master Servicer other than itself or an Affiliate pursuant to this Section 6.04, it may reduce the
Excess Servicing Fee Rate to the extent reasonably necessary (in the sole discretion of the Trustee) for the Trustee to appoint
a qualified successor Master Servicer that meets the requirements of this Section 6.04.


 


(c)            
The Operating Advisor may resign from its obligations and duties under this Agreement (a) upon thirty (30) days’ prior
written notice to the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Asset
Representations Reviewer and the Controlling Class Representative and (b) upon the appointment of, and the acceptance of
such appointment by, a successor operating advisor that is an Eligible Operating Advisor and receipt by the Trustee of Rating
Agency Confirmation from each Rating Agency. Except as provided in Section 6.04(d), no such resignation by the Operating
Advisor shall become effective until a replacement Operating Advisor shall have assumed the resigning Operating Advisor’s
responsibilities and obligations under this Agreement. The successor entity assuming the obligations of the Operating Advisor
under this Agreement shall be entitled to the compensation to which the Operating Advisor would have been entitled hereunder after
the date of assumption of such obligations. If no successor Operating Advisor can be obtained to perform


 






    	-361- 



     


    

 


such obligations for
such compensation, additional amounts payable to such successor Operating Advisor shall be payable out of the Trust; provided
that, for so long as no Consultation Termination Event has occurred and is continuing, the Trustee shall consult with the
Controlling Class Representative prior to the appointment of a successor Operating Advisor at an operating advisor compensation
in excess of that permitted to the terminated Operating Advisor. If no successor Operating Advisor has been appointed and accepted
such appointment within 60 days after the resigning Operating Advisor’s giving of notice of resignation, the resigning Operating
Advisor may petition any court of competent jurisdiction for appointment of a successor. The resigning Operating Advisor shall
pay all costs and expenses associated with its resignation and the transfer of its duties (including costs and expenses incurred
by each other party hereto, the Trust and the Rating Agencies) pursuant to this Section 6.04.


 


(d)           
In addition, in the event that, at any time following the second anniversary of the Closing Date, there are no Classes of Certificates
outstanding other than the Control Eligible Certificates, the Class S Certificates and the Class R Certificates, then all of the
rights and obligations of the Operating Advisor under this Agreement shall terminate without payment of any penalty or termination
fee (other than any rights or obligations that accrued prior to the date of such termination (including the right to receive all
amounts accrued and owing to it under this Agreement) and other than indemnification rights arising out of events occurring prior
to such termination). If the Operating Advisor is terminated pursuant to the foregoing sentence, then no replacement Operating
Advisor shall be appointed.


 


Section 6.05      
Rights of the Depositor, the Trustee and the Certificate Administrator in Respect of the Master Servicer and Special Servicer. The
Master Servicer and the Special Servicer shall afford the Depositor, the Trustee, the Certificate Administrator and, subject to
Section 12.13 of this Agreement, each Rating Agency, upon reasonable notice, during normal business hours access to
all records maintained by it in respect of its rights and obligations hereunder and access to its officers responsible for such
obligations, if reasonably related to the performance of the obligations of such Person under this Agreement. Upon request, if
reasonably related to the performance of the obligations of such Person under this Agreement, the Master Servicer and the Special
Servicer shall furnish to the Depositor, each of the Underwriters, the Initial Purchasers, the Master Servicer, the Special Servicer,
the Trustee and the Certificate Administrator its most recent publicly available annual financial statements or those of its public
parent. The Depositor is not obligated to monitor or supervise the performance of the Master Servicer, the Special Servicer, the
Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator or the Trustee under this Agreement. The
Depositor may, but is not obligated to, enforce the obligations of the Master Servicer or the Special Servicer hereunder which
are in default and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of such Person
hereunder or exercise its rights hereunder, provided that the Master Servicer and the Special Servicer shall not be relieved
of any of its obligations hereunder by virtue of such performance by the Depositor or its designee. In the event the Depositor
or its designee undertakes any such action it will be reimbursed by the Trust Fund from the Collection Account as provided in
Section 3.06 and Section 6.03 of this Agreement to the extent not recoverable from the Master Servicer
or the Special Servicer, as applicable. None of the Depositor, the Trustee, the Certificate Administrator, the Master Servicer
(with respect to the Special Servicer) or the Special Servicer (with respect to the Master Servicer) shall have any responsibility
or liability for any action or failure to act by the Master Servicer or the Special Servicer, and no


 






    	-362- 



     


    

 


such Person is obligated
to monitor or supervise the performance of the Master Servicer or the Special Servicer under this Agreement or otherwise. Neither
the Master Servicer nor the Special Servicer shall have any responsibility or liability for any action or failure to act by the
Depositor, the Trustee or the Certificate Administrator and neither such Person is obligated to monitor or supervise the performance
of the Depositor, the Trustee or the Certificate Administrator under this Agreement or otherwise.


 


Each
of the Trustee, the Certificate Administrator, the Depositor, the Master Servicer, and the Special Servicer shall furnish such
reports, certifications and information as are reasonably requested by the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer or the Special Servicer, as applicable, in order to enable such requesting party to perform its duties hereunder,
provided that for the avoidance of doubt, this shall not require any Person to prepare any reports, Certificates and information
not required to be prepared hereunder.


 


Neither
the Master Servicer nor the Special Servicer shall be under any obligation to disclose confidential or proprietary information
pursuant to this Section.


 


Section 6.06      
Master Servicer, Special Servicer as Owner of a Certificate. The Master Servicer or an Affiliate of the Master Servicer
or the Special Servicer or an Affiliate of the Special Servicer may become the Holder (or with respect to a Global Certificate,
Certificate Owner) of any Certificate with the same rights it would have if it were not the Master Servicer or the Special Servicer
or an Affiliate thereof, except as otherwise expressly provided herein. If, at any time during which the Master Servicer or the
Special Servicer or an Affiliate of the Master Servicer or the Special Servicer is the Holder or Certificate Owner of any Certificate,
the Master Servicer or the Special Servicer proposes to take action (including for this purpose, omitting to take action) that
(i) is not expressly prohibited by the terms hereof and would not, in the Master Servicer’s or the Special Servicer’s
good faith judgment, violate the Servicing Standard, and (ii) if taken, might nonetheless, in the Master Servicer’s
or the Special Servicer’s good faith judgment, be considered by other Persons to violate the Servicing Standard, the Master
Servicer or the Special Servicer may seek the approval of the Certificateholders and any affected Serviced Companion Loan Holder
to such action by delivering to the Trustee and the Certificate Administrator a written notice that (i) states that it is
delivered pursuant to this Section 6.06, (ii) identifies the Percentage Interest in each Class of Certificates
beneficially owned by the Master Servicer or the Special Servicer or an Affiliate of the Master Servicer or the Special Servicer,
and (iii) describes in reasonable detail the action that the Master Servicer or the Special Servicer proposes to take. The
Certificate Administrator, upon receipt of such notice, shall forward it to the Certificateholders (other than the Master Servicer
and its Affiliates or the Special Servicer and its Affiliates, as appropriate) together with such instructions for response as
the Certificate Administrator shall reasonably determine. If at any time Certificateholders holding greater than 50% of the Voting
Rights of all Certificateholders (calculated without regard to the Certificates beneficially owned by the Master Servicer or its
Affiliates or the Special Servicer or its Affiliates) and any affected Serviced Companion Loan Holder shall have consented in
writing to the proposal described in the written notice, and if the Master Servicer or the Special Servicer shall act as proposed
in the written notice, such action shall be deemed to comply with the Servicing Standard. The Certificate Administrator shall
be entitled to reimbursement from the Master Servicer or the Special Servicer, as applicable, of the reasonable expenses of the
Certificate Administrator incurred pursuant to this paragraph. It is not the intent of the foregoing provision that the Master
Servicer or the Special


 






    	-363- 



     


    

 


Servicer be permitted to invoke the procedure set forth herein with respect
to routine servicing matters arising hereunder, except in the case of unusual circumstances.


 


Section 6.07      
Rating Agency Fees. The Depositor shall pay (or cause to be paid) the annual fees of each Rating Agency including,
but not limited to, surveillance fees.


 


Section 6.08      
Termination of the Special Servicer.


 


(a)            
At any time prior to the occurrence and continuance of a Control Termination Event (or if a Control Termination Event has occurred
but is no longer continuing), the Controlling Class Representative shall be entitled to terminate the rights (subject to Section 3.12,
Section 6.03, Section 6.08(b) and Section 6.08(g) of this Agreement) and obligations of the Special
Servicer under this Agreement with respect to the Serviced Loans (exclusive of any Serviced Outside Controlled Loan Combination
and any Excluded Mortgage Loan), with or without cause, upon ten (10) Business Days’ notice to the Special Servicer, the
Master Servicer, the Certificate Administrator and the Trustee and, in the case of a termination of the Special Servicer with
respect to a Serviced Loan Combination, the related Companion Loan Holder(s).


 


With
respect to any Serviced Outside Controlled Loan Combination, the related Outside Controlling Note Holder shall be entitled, to
the extent provided in the related Co-Lender Agreement, at any time to terminate the rights (subject to Section 3.12, Section
6.03, Section 6.08(b) and Section 6.08(g) of this Agreement) and obligations of the Special Servicer under this
Agreement solely with respect to such Serviced Outside Controlled Loan Combination, with or without cause, upon ten (10) Business
Days’ notice to the Special Servicer, the Master Servicer, the Certificate Administrator and the Trustee and any other related
Companion Loan Holder(s).


 


Upon
a termination (pursuant to the first or the second paragraph of this Section 6.08(a)) or a resignation (pursuant to Section
6.04(b) of this Agreement) of the Special Servicer with respect to the applicable Serviced Loan(s), the Controlling Class
Representative (with respect to the Serviced Loans other than any Serviced Outside Controlled Loan Combination) or the related
Outside Controlling Note Holder (with respect to a Serviced Outside Controlled Loan Combination), as applicable, shall appoint
a successor Special Servicer with respect to the Serviced Loans (exclusive of any Serviced Outside Controlled Loan Combination)
or the related Serviced Outside Controlled Loan Combination, as the case may be; provided, however, that (i) such successor shall
meet the requirements set forth in Section 7.02 of this Agreement, (ii) the Controlling Class Representative (with respect
to the Serviced Loans other than any Serviced Outside Controlled Loan Combination) or the related Outside Controlling Note Holder
(with respect to a Serviced Outside Controlled Loan Combination), as applicable, shall (at no expense to the Trust) obtain and
deliver to the Certificate Administrator and the Trustee a Rating Agency Confirmation with respect to such proposed successor
acting as a Special Servicer and (iii) in the case of the appointment of a successor Special Servicer with respect to a Serviced
Loan Combination, the Controlling Class Representative (with respect to the Serviced Loans other than any Serviced Outside Controlled
Loan Combination) or the related Outside Controlling Note Holder (with respect to a Serviced Outside Controlled Loan Combination),
as applicable, shall (at no expense to the Trust or any related Other Securitization Trust) obtain and deliver to the certificate
administrator (if any) and the trustee for each related Other Securitization Trust (with a


 






    	-364- 



     


    

 


copy to the Certificate Administrator
and the Trustee) a Companion Loan Rating Agency Confirmation with respect to such proposed successor acting as a Special Servicer
for each related Serviced Companion Loan.


 


Following
the occurrence and during the continuance of a Control Termination Event, upon (i) the written direction of Holders of Certificates
evidencing not less than 25% of the Voting Rights of the Certificates (other than the Class S and Class R Certificates) requesting
a vote to terminate and replace the Special Servicer (with respect to all of the Serviced Loans other than any Serviced Outside
Controlled Loan Combination) with a proposed successor Special Servicer, (ii) payment by such Holders to the Certificate
Administrator of the reasonable fees and expenses to be incurred by the Certificate Administrator in connection with administering
such vote and (iii) delivery by such Holders to the Certificate Administrator and the Trustee of a Rating Agency Confirmation
with respect to the termination of the existing Special Servicer and the replacement thereof with the proposed successor (with
the reasonable fees and out-of-pocket costs and expenses associated with obtaining such Rating Agency Confirmation to be an expense
of such Holders), the Certificate Administrator shall promptly provide written notice of the requested vote to all Certificateholders
by posting such notice on its internet website and by mailing at their addresses appearing in the Certificate Register. Upon the
affirmative vote of (a) the Holders of Certificates (other than the Class S and Class R Certificates) evidencing at least
66 2/3% of the Voting Rights allocable to the Certificates of those Holders that voted on such matter (provided that Holders
representing the applicable Certificateholder Quorum vote on the matter) or (b) the Holders of Non-Reduced Certificates evidencing
more than 50% of the Voting Rights allocable to each Class of Non-Reduced Certificates, the Trustee shall terminate all of the
rights (subject to Section 3.12, Section 6.03 and Section 6.08(g) of this Agreement) and obligations
of the Special Servicer under this Agreement with respect to the Serviced Loans (other than any Serviced Outside Controlled Loan
Combination), and the proposed successor Special Servicer shall succeed to the duties of the Special Servicer with respect to
the Serviced Loans (other than any Serviced Outside Controlled Loan Combination) all as if a removal and replacement were occurring
pursuant to Section 7.01 and Section 7.02 of this Agreement; provided that if such affirmative
vote is not achieved within 180 days of the initial request for a vote to terminate and replace the Special Servicer, then
such vote 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
Certificate Administrator shall include on each Distribution Date Statement a statement that each Certificateholder and Certificate
Owner may access notices on the Certificate Administrator’s Website and each Certificateholder and Certificate Owner may
register to receive e-mail notifications when such notices are posted on the Certificate Administrator’s Website; provided
that the Certificate Administrator shall be entitled to reimbursement from the requesting Certificateholders for the reasonable
expenses of posting such notices.


 


(b)           
With respect to the Serviced Loans, if the Operating Advisor determines, in its sole discretion exercised in good faith, that
(1) the Special Servicer has failed to comply with


 






    	-365- 



     


    

 


the Servicing Standard and (2) a replacement of the Special Servicer would
be in the best interest of the Certificateholders (as a collective whole), the Operating Advisor shall deliver to the Trustee
and the Certificate Administrator, with a copy to the Special Servicer, a written recommendation in the form of Exhibit T
attached hereto (which form may be modified or supplemented from time to time to cure any ambiguity or error or to incorporate
any additional information, subject to compliance of such form with the terms and provisions of this Agreement, provided
that in no event shall the information or any other content included in such written recommendation contravene any provision of
this Agreement) detailing the reasons supporting its position (along with relevant information justifying its recommendation),
recommending a replacement special servicer with respect to the Serviced Loans, meeting the applicable requirements of this Agreement,
which recommended special servicer has agreed to succeed the then-current Special Servicer if appointed in accordance herewith,
and requesting a vote on whether the existing Special Servicer should be replaced. In any such event, the Certificate Administrator
shall promptly post a copy of such recommendation on the Certificate Administrator’s Website and by mail send notice of
such recommendation to all Certificateholders, asking them to vote whether they wish to remove the Special Servicer with respect
to the Serviced Loans. Upon (i) the affirmative vote of the Holders of Certificates evidencing at least a majority of the
aggregate outstanding principal balance of the Certificates of those Holders that voted on the matter (provided that Holders
representing the applicable Certificateholder Quorum vote on the matter within 180 days of the initial request for a vote
(which, for the avoidance of doubt, is the date on the which the aforementioned notice was mailed to the Certificateholders))
and (ii) receipt of Rating Agency Confirmation from each Rating Agency by the Certificate Administrator following satisfaction
of the foregoing clause (i), the Trustee shall (x) terminate all of the rights (subject to Section 3.12,
Section 6.03 and Section 6.08(g) of this Agreement) and obligations of the Special Servicer under this Agreement
with respect to the Serviced Loans, (y) appoint the recommended successor Special Servicer and (z) promptly notify such outgoing
Special Servicer of the effective date of such termination. The reasonable fees and out-of-pocket costs and expenses associated
with obtaining such Rating Agency Confirmation and administering such vote shall be an Additional Trust Fund Expense. If such
affirmative vote of the Holders of the required Certificates contemplated by clause (i) of the second preceding sentence is not
achieved within 180 days of the initial request for such vote (which, for the avoidance of doubt, is the date on the which
the aforementioned notice was mailed to the Certificateholders), then the Trustee shall have no obligation to remove the Special
Servicer and such recommendation shall lapse and have no force or effect. Prior to the appointment of any replacement special
servicer, such replacement special servicer shall have agreed to succeed to the obligations of the Special Servicer under this
Agreement with respect to the Serviced Loans, and to act as the Special Servicer’s successor hereunder. No penalty or fee
shall be payable to the terminated Special Servicer with respect to any termination pursuant to this Section 6.08(b).
If any Special Servicer is terminated pursuant to this Section 6.08(b), then (notwithstanding anything herein to the contrary)
the terminated party may not subsequently be re-appointed as the Special Servicer hereunder pursuant to any other subsection of
this Section 6.08, any other section of this Agreement or any Co-Lender Agreement.


 


(c)            
In no event may a successor Special Servicer be a current or former Operating Advisor or Asset Representations Reviewer or any
Affiliate (including any Risk Retention Affiliate) of such current or former Operating Advisor or Asset Representations Reviewer.
Further, such successor must be a Person that (i) satisfies all of the eligibility requirements applicable to special servicers
contained in this Agreement and, in the case of a

Serviced Loan Combination, in the related Co-Lender Agreement, (ii) is
not obligated or allowed to pay the Operating Advisor (x) any fees or otherwise compensate the Operating Advisor in respect
of its obligations under this Agreement or (y) for the appointment of the successor Special Servicer or the recommendation
by the Operating Advisor for the replacement Special Servicer to become the Special Servicer, (iii) is not entitled to waive
any compensation from the Operating Advisor and (iv) is not entitled to receive any fee from the Operating Advisor for its
appointment as successor Special Servicer, in each case, unless expressly approved by 100% of the Certificateholders.


 


(d)           
The appointment of any such successor Special Servicer shall not relieve the Master Servicer or the Trustee of their respective
obligations to make Advances as set forth herein; provided, however, the initial Special Servicer specified in Section 3.21(a)
of this Agreement shall not be liable for any actions or any inaction of such successor Special Servicer. Any termination
fee payable to the terminated Special Servicer and any costs incurred by the Trust or the terminated Special Servicer in connection
with the replacement of a Special Servicer shall be paid by the Controlling Class Representative, the Certificateholders or the
Serviced Companion Loan Holder so terminating the Special Servicer and shall not in any event be an expense of the Trust Fund.


 


(e)            
No termination of the Special Servicer and appointment of a successor Special Servicer shall be effective until (i) the successor
Special Servicer shall have executed and delivered to the Trustee and the Certificate Administrator an agreement which contains
an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed
or observed by the Special Servicer under this Agreement from and after the date of such agreement, (ii) the Depositor and, if
applicable, each related Other Depositor shall have received the written notice and information with respect to the successor
Special Servicer as set forth in Section 10.02(a) and (iii) subject to Section 12.13 of this Agreement,
each Rating Agency has delivered to the Trustee and the Certificate Administrator a Rating Agency Confirmation and, if required
pursuant to Section 6.08(a), each Companion Loan Rating Agency has delivered to the Trustee and the Certificate Administrator
and their respective counterparts with respect to the Other Securitization Trust a Companion Loan Rating Agency Confirmation,
in each case with respect to such termination and appointment of a successor.


 


(f)            
Any successor Special Servicer shall be deemed to make the representations and warranties provided for in Section 2.06(a)
of this Agreement mutatis mutandis as of the date of its succession.


 


(g)           
In the event that the Special Servicer is terminated pursuant to this Section 6.08, the Trustee shall, by notice in
writing to the Special Servicer, terminate all of its rights and obligations under this Agreement and in and to the applicable
Mortgage Loan(s) and/or Serviced Loan Combinations and the proceeds thereof, other than any rights the Special Servicer may have
hereunder as a Certificateholder and any rights or obligations that accrued prior to the date of such termination (including,
without limitation, the right to receive all amounts accrued or owing to it under this Agreement, plus interest at the Advance
Rate on such amounts until received to the extent such amounts bear interest as provided in this Agreement, with respect to periods
prior to the date of such termination and the right to the benefits of Section 6.03 of this Agreement and the right
to receive ongoing Workout Fees in accordance with the terms hereof).

(h)           
If (1) a replacement special servicer is appointed with respect to a Serviced Loan Combination or any related REO Property in
accordance with Article VII or this Section 6.08 or (2) an Excluded Mortgage Loan Special Servicer is appointed
with respect to an Excluded Special Servicer Mortgage Loan, such that there are multiple parties acting as Special Servicer hereunder,

applicable Loan Combination Special Servicer, insofar as such duties and obligations relate to the subject Serviced Loan Combination
or any related REO Property, (B) the applicable Excluded Mortgage Loan Special Servicer, insofar as such duties and obligations

shall mean each of the Loan Combination Special Servicers, the Excluded Mortgage Loan Special Servicers (if any) and the General
Special Servicer); (ii) when used in the context of identifying the recipient of any information, funds, documents, instruments

Special Servicer, in all other cases; (iii) when used in the context of granting the Special Servicer the right to purchase
all of the Mortgage Loans and all other property held by the Trust Fund pursuant to Section 9.01 of this Agreement,

Servicer” shall mean the applicable Loan Combination Special Servicer, the applicable Excluded Mortgage Loan Special Servicer

special servicer with respect to the Mortgage Pool (exclusive of (A) any Serviced Loan Combination or related REO Property as

    	-368- 



     


    

 


(j)             
Notwithstanding anything to the contrary contained in this Section 6.08, if the Special Servicer obtains knowledge
that it is, or has become, a Borrower Party with respect to any Mortgage Loan or Loan Combination, then the Special Servicer shall
resign in such capacity with respect to such Excluded Special Servicer Mortgage Loan. Prior to the occurrence and continuance
of a Control Termination Event, if the Excluded Special Servicer Mortgage Loan is not also an Excluded Mortgage Loan, the Controlling
Class Representative shall appoint (and replace with or without cause) the Excluded Mortgage Loan Special Servicer, as successor
to the resigning Special Servicer, for the related Excluded Special Servicer Mortgage Loan in accordance with this Agreement.
If such Excluded Special Servicer Mortgage Loan is also an Excluded Mortgage Loan, the largest Controlling Class Certificateholder
(by Certificate Balance) that is not an Excluded Controlling Class Holder shall appoint (and replace with or without cause) the
Excluded Mortgage Loan Special Servicer for the related Excluded Special Servicer Mortgage Loan in accordance with this Agreement.
If a Control Termination Event has occurred and is continuing, neither the Controlling Class Representative nor any other Controlling
Class Certificateholder shall be entitled to remove or replace the Special Servicer with respect to any Excluded Special Servicer
Mortgage Loan. If a Control Termination Event has occurred and is continuing but prior to the occurrence and continuance of a
Consultation Termination Event, the largest Controlling Class Certificateholder that is not an Excluded Controlling Class Holder
shall have the right to appoint the Excluded Mortgage Loan Special Servicer.


 


If
a Consultation Termination Event has occurred and is continuing, or if neither the Controlling Class Representative nor any Controlling
Class Certificateholder is entitled to appoint the Excluded Mortgage Loan Special Servicer for the related Excluded Special Servicer
Mortgage Loan pursuant to the first paragraph of this Section 6.08(j) (or if, despite being so entitled to appoint the
Excluded Mortgage Loan Special Servicer for the related Excluded Special Servicer Mortgage Loan pursuant to the first paragraph
of this Section 6.08(j), neither the Controlling Class Representative nor any Controlling Class Certificateholder has appointed
a Excluded Mortgage Loan Special Servicer for the related Excluded Special Servicer Mortgage within 30 days), then the Certificate
Administrator shall provide written notice to the resigning Special Servicer that such Excluded Mortgage Loan Special Servicer
has not been appointed and such resigning Special Servicer shall use reasonable efforts to appoint such Excluded Mortgage Loan
Special Servicer. In the event that the resigning Special Servicer is required to appoint an Excluded Mortgage Loan Special Servicer,
the resigning Special Servicer shall not have any liability for the actions or inactions of the newly appointed Excluded Mortgage
Loan Special Servicer or with respect to the identity of the applicable Excluded Mortgage Loan Special Servicer (so long as, on
the date of appointment, the appointment of such Excluded Special Servicer meets the criteria set forth in this Agreement). It
shall be a condition to the appointment of any such Excluded Special Servicer that (i) such Excluded Special Servicer has delivered
a Rating Agency Confirmation with respect such appointment to the Certificate Administrator and the Trustee and, if the related
Excluded Special Servicer Mortgage Loan is part of a Serviced Loan Combination, a Companion Loan Rating Agency Confirmation with
respect to such appointment to the certificate administrator (if any) and the trustee for each related Other Securitization Trust
(with a copy to the Certificate Administrator and the Trustee), (ii) such Excluded Special Servicer satisfies all of the eligibility
requirements applicable to the Special Servicer set forth in this Agreement and (iii) such Excluded Special Servicer delivers
to the Depositor (and the Certificate Administrator) and any applicable Other Depositor (and any applicable Other Exchange Act
Reporting Party), the information, if any,


 






    	-369- 



     


    

 


required under Item 6.02 of Form 8-K pursuant to the Exchange Act regarding itself
in its role as Excluded Special Servicer.


 


If
at any time the Person that had acted as the Special Servicer for any Mortgage Loan or Loan Combination prior to such Mortgage
Loan or Loan Combination, as the case may be, becoming an Excluded Special Servicer Mortgage Loan is no longer a Borrower Party
(including, without limitation, as a result of the related Mortgaged Property becoming REO Property or an assumption of the Excluded
Special Servicer Mortgage Loan) with respect to such Mortgage Loan or Loan Combination, as the case may be, (1) the related Excluded
Mortgage Loan Special Servicer shall resign, (2) such Mortgage Loan or Loan Combination, as the case may be, shall no longer be
an Excluded Special Servicer Mortgage Loan, (3) such original Special Servicer shall become the Special Servicer again for such
Mortgage Loan or Loan Combination, as the case may be, and (4) such original Special Servicer shall be entitled to all Special
Servicing Compensation and Additional Special Servicing Compensation with respect to such Mortgage Loan or Loan Combination, as
the case may be, earned during such time on and after such Mortgage Loan or Loan Combination, as the case may be, is no longer
an Excluded Special Servicer Mortgage Loan.


 


The
Excluded Mortgage Loan Special Servicer shall perform all of the obligations of the Special Servicer for the related Excluded
Special Servicer Mortgage Loan and will be entitled to all Special Servicing Compensation and Additional Special Servicing Compensation
with respect to such Excluded Special Servicer Mortgage Loan earned after its appointment as the Excluded Mortgage Loan Special
Servicer and during such time as the related Mortgage Loan is an Excluded Special Servicer Mortgage Loan (provided that
the Special Servicer shall remain entitled to all Special Servicing Compensation and Additional Special Servicing Compensation
with respect to the Mortgage Loans and Serviced Loan Combinations that are not Excluded Special Servicer Mortgage Loans during
such time).


 


Notwithstanding
anything to the contrary in this Section 6.08(j), in the case of any Serviced Outside Controlled Loan Combination, the
related Outside Controlling Note Holder will have the right to appoint an Excluded Mortgage Loan Special Servicer.


 


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


 


Section 6.09     
The Directing Holder and the Controlling Class Representative.


 


(a)            
The related Directing Holder (unless, if the Controlling Class Representative is the related Directing Holder, a Control Termination
Event has occurred and is continuing or the subject Mortgage Loan is an Excluded Mortgage Loan) shall be entitled: (1) with respect
to the applicable Serviced Loan(s) that are Specially Serviced Loan(s), to advise the Special Servicer as to all Major Decisions;
(2) with respect to the applicable Serviced Loan(s) that are Performing Serviced Loan(s), to advise the Special Servicer as to
all Major Decisions; and (3) in the case of the Controlling Class Representative, with respect to any Outside Serviced Mortgage


 






    	-370- 



     


    

 


Loan, to exercise consultation and, to the extent provided in Section 3.01(i), consent rights (if any) and attend annual
meetings with the related Outside Servicer and the related Outside Special Servicer, in each case, to the extent the holder of
such Outside Serviced Mortgage Loan is entitled to such rights pursuant to the related Co-Lender Agreement.


 


In
addition, except as set forth in, and in any event subject to, Section 6.09(b) and the subsequent paragraphs of this
Section 6.09(a), (1) the Master Servicer shall not be permitted to take any of the actions constituting a Major
Decision unless the Master Servicer and the Special Servicer mutually agree that the Master Servicer shall take such action, subject
to the consent of the Special Servicer, who shall have 15 Business Days (or 60 days with respect to the determination of
an Acceptable Insurance Default) (from the date that the Special Servicer receives the information from the Master Servicer) to
analyze and make a recommendation regarding such Major Decision (provided that if the Special Servicer does not consent,
or notify the Master Servicer that it will not consent, to such Major Decision within the required 15 Business Days or 60 days,
as applicable, the Special Servicer shall be deemed to have consented to such Major Decision), and (2) the Special
Servicer shall not be permitted (if the Controlling Class Representative is the related Directing Holder, for so long as no Control
Termination Event exists) to take, or to consent to the Master Servicer’s taking, any of the actions constituting a Major
Decision as to which the related Directing Holder has objected in writing within ten (10) Business Days (or in the case of a determination
of an Acceptable Insurance Default, twenty (20) days (or, in the case of a Serviced Outside Controlled Loan Combination, such
other period contemplated by the related Co-Lender Agreement)) after receipt of the related Major Decision Reporting Package from
the Special Servicer (provided that (i) if such written objection has not been received by the Special Servicer within
such ten (10) Business Day period or twenty (20) day period (or, in the case of a Serviced Outside Controlled Loan Combination,
such other period contemplated by the related Co-Lender Agreement), as applicable, then the related Directing Holder will be deemed
to have approved such action and (ii) the consent of the Controlling Class Representative shall not be required in connection
with a Major Decision with respect to an Excluded Mortgage Loan).


 


Furthermore,
each of (x) the Controlling Class Representative (with respect to each Serviced Loan other than (i) a Serviced Outside Controlled
Loan Combination and (ii) an Excluded Mortgage Loan), provided that a Control Termination Event does not exist, and (y) the
related Outside Controlling Note Holder (with respect to a Serviced Outside Controlled Loan Combination) may direct the Special
Servicer to take, or to refrain from taking, such other actions with respect to the applicable Serviced Loan(s) as such party
may reasonably deem advisable or as to which provision is otherwise made herein.


 


Notwithstanding
the foregoing, if the Controlling Class Representative is the related Directing Holder, the Special Servicer is not required to
obtain the consent of the Controlling Class Representative prior to taking, or consenting to the Master Servicer’s taking
of, any Major Decision following the occurrence and during the continuance of a Control Termination Event; provided that,
the Special Servicer shall consult (on a non-binding basis) with (i) the Controlling Class Representative (after the occurrence
and during the continuance of a Control Termination Event and only until the occurrence and continuance of a Consultation Termination
Event, but other than with respect to any Excluded Mortgage Loan) and (ii) the Operating Advisor (after the occurrence and during
the continuance of an Operating Advisor Consultation Trigger Event) in connection with any Major Decision and consider alternative
actions recommended by


 






    	-371- 



     


    

 


the Controlling Class Representative and the Operating Advisor, but, in the case of the Controlling Class
Representative, only to the extent such consultation with, or consent of, the Controlling Class Representative would have been
required prior to the occurrence and continuance of such Control Termination Event; and provided, further, that
the Controlling Class Representative (with respect to any Serviced Outside Controlled Loan Combination that does not include an
Excluded Mortgage Loan and for so long as no Consultation Termination Event exists) may consult regarding a Serviced Outside Controlled
Loan Combination only if and to the extent that the holder of the related Split Mortgage Loan is granted consultation rights under
the related Co-Lender Agreement. For the avoidance of doubt, with respect to any Serviced Outside Controlled Loan Combination
(which, for the avoidance of doubt, shall include, without limitation, any Servicing Shift Loan Combination prior to the related
Servicing Shift Date), the Special Servicer shall be responsible for obtaining any consent or deemed consent of the related Outside
Controlling Note Holder for “Major Decisions” (as such term or any analogous term is defined in the related Co-Lender
Agreement) to the extent such consent is required under this Agreement or under the terms of the related Co-Lender Agreement.
Notwithstanding the foregoing, the Controlling Class Representative shall have no consent or consultation rights with respect
to Major Decisions with respect to any Excluded Mortgage Loan. The Special Servicer shall provide all information reasonably requested
by the Controlling Class Representative and/or the Operating Advisor, as applicable, and in the Special Servicer’s possession
that is necessary in order for the Controlling Class Representative and/or the Operating Advisor to exercise their respective
consultation rights set forth in the first sentence of this paragraph.


 


With
respect to a Servicing Shift Loan Combination that is a Serviced Outside Controlled Loan Combination, prior to the related Servicing
Shift Date, no request for approval of the Controlling Class Representative shall be made on any matter related to such Servicing
Shift Loan Combination, except that the Controlling Class Representative (prior to the occurrence and continuance of a Consultation
Termination Event and only if the related Servicing Shift Mortgage Loan is not an Excluded Mortgage Loan) may exercise the consultation
rights, if any, of the holder of the related Servicing Shift Mortgage Loan with respect to Major Decisions and any proposed sale
of such Servicing Shift Mortgage Loan set forth in the applicable Co-Lender Agreement. In addition, after the occurrence and during
the continuance of an Operating Advisor Consultation Trigger Event, the Operating Advisor will be entitled, while a Servicing
Shift Mortgage Loan is serviced hereunder, to consult on a non-binding basis with the Special Servicer and propose alternative
courses of action and provide other feedback in respect of any Major Decisions and any proposed sale of such Servicing Shift Mortgage
Loan.


 


With
respect to each Major Decision regarding a Serviced Loan as to which the Directing Holder has consent or consultation rights pursuant
to this Section 6.09, the Special Servicer shall provide the related Major Decision Reporting Package to the Directing
Holder, simultaneously with the Special Servicer’s request for the Directing Holder’s consent or input regarding the
related Major Decision. The Special Servicer shall provide each Major Decision Reporting Package to the Operating Advisor: (i)
as to Specially Serviced Loans, prior to the occurrence and continuance of a Control Termination Event and an Operating Advisor
Consultation Trigger Event, promptly after the Special Servicer receives the Directing Holder’s approval or deemed approval
of such Major Decision Reporting Package; and (ii) as to all Serviced Loans, following the occurrence and continuance of an Operating
Advisor Consultation Trigger Event (whether or not a Control Termination Event is continuing), simultaneously with the Special


 






    	-372- 



     


    

 


Servicer’s written request for the Operating Advisor’s input regarding the related Major Decision. With respect to
any particular Major Decision and related Major Decision Reporting Package provided to the Operating Advisor pursuant to this
Section 6.09(a), the Special Servicer shall make available to the Operating Advisor one or more Servicing Officers with
relevant knowledge regarding the applicable Mortgage Loan and such Major Decision in order to address reasonable questions that
the Operating Advisor may have relating to, among other things, such Major Decision and potential conflicts of interest with respect
to such Major Decision.


 


Notwithstanding
anything in this Agreement to the contrary, in the event that the Special Servicer or Master Servicer (in the event the Master
Servicer is otherwise authorized by this Agreement to take such action), as applicable, determines that immediate action, with
respect to a Major Decision, or any other matter requiring consent of, or consultation with, the related Directing Holder, is
necessary to protect the interests of the Certificateholders and, with respect to any Serviced Loan Combination, the related Serviced
Companion Loan Holder(s) (as a collective whole as if such Certificateholders and, with respect to any Serviced Loan Combination,
the related Serviced Companion Loan Holder(s) constituted a single lender (and, with respect to a Serviced AB Loan Combination,
taking into account the subordinate nature of the related Subordinate Companion Loan(s))), the Special Servicer or Master Servicer,
as applicable, may take any such action without waiting for the Directing Holder’s (or, if applicable, the Special Servicer’s)
response.


 


Also
notwithstanding anything in this Agreement to the contrary, no direction, objection, advice or consultation on the part of a Directing
Holder contemplated by this Agreement, may require or cause the Master Servicer or the Special Servicer to violate the terms of
any Mortgage Loan or Serviced Loan Combination, any provision of any related Loan Documents, any related Co-Lender Agreement,
any intercreditor agreement, applicable law, this Agreement or the REMIC Provisions, including without limitation each of the
Master Servicer’s and the Special Servicer’s obligation to act in accordance with the Servicing Standard, or expose
any Certificateholder, the Trust Fund, any Mortgage Loan Seller (other than with respect to enforcing the rights and remedies
against such Mortgage Loan Seller pursuant to this Agreement or the related Mortgage Loan Purchase Agreement with respect to any
Material Defect) or any party to this Agreement or their respective Affiliates, officers, directors, employees or agents to any
claim, suit or liability, or cause either Trust REMIC to fail to qualify as a REMIC or the Grantor Trust to fail to qualify as
a grantor trust for federal income tax purposes, or result in the imposition of a “prohibited transaction” or “prohibited
contribution” tax under the REMIC Provisions, or materially expand the scope of the Master Servicer’s or the Special
Servicer’s responsibilities under this Agreement or any Co-Lender Agreement or cause the Master Servicer or the Special
Servicer to act, or fail to act, in a manner that is not in the best interests of the Certificateholders and/or the Serviced Companion
Loan Holders.


 


In
the event the Special Servicer or Master Servicer, as applicable, determines that a refusal to consent by a Directing Holder or
any advice from a Directing Holder would otherwise cause the Special Servicer or Master Servicer, as applicable, to violate the
terms of any Loan Documents, any related Co-Lender Agreement or mezzanine intercreditor agreement, applicable law, the REMIC Provisions
or this Agreement, including without limitation, the Servicing Standard, the Special Servicer or Master Servicer, as applicable,
shall disregard such refusal to consent or advise and notify in writing such Directing Holder, the Trustee and, for posting to
the

Rule 17g-5 Information Provider’s Website pursuant to Section 12.13 of this Agreement, the Rule 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 Master Servicer or Special Servicer in accordance with the direction of or approval of a Directing
Holder that does not violate any law or the Servicing Standard or any other provisions of this Agreement, will not result in any
liability on the part of the Master Servicer or the Special Servicer.


 


For
so long as no Control Termination Event has occurred and is continuing, the Controlling Class Representative shall be entitled,
with respect to each Outside Serviced Mortgage Loan other than any Excluded Mortgage Loan, to exercise the consent or approval
rights set forth in Section 3.01(i) of this Agreement; and for so long as no Consultation Termination Event has occurred
and is continuing, the Controlling Class Representative shall be entitled, with respect to each Outside Serviced Mortgage Loan
other than any Excluded Mortgage Loan, to exercise any consultation rights permitted under the related Co-Lender Agreement in
respect of “Major Decisions” (or any analogous concept) and the implementation of “Asset Status Reports”
(or any analogous concept) under, and within the meaning of, the applicable Outside Servicing Agreement and attend an annual meeting
with the related Outside Servicer and the related Outside Special Servicer, in each case, to the extent the holder of such Outside
Serviced Mortgage Loan is entitled to such rights pursuant to the related Co-Lender Agreement; provided that, after the
occurrence and during the continuance of an Operating Advisor Consultation Trigger Event, any such consultation rights permitted
under the related Co-Lender Agreement in respect of “Major Decisions” (or any analogous concept) shall be exercised
by the Controlling Class Representative jointly with the Operating Advisor.


 


The
Directing Holder will have no liability to the Trust Fund or Certificateholders for any action taken, or for refraining from the
taking of any action, pursuant to this Agreement, or for error in judgment; provided, however, that the Controlling
Class Representative will not be protected against any liability to any Controlling Class Certificateholder that would otherwise
be imposed by reason of willful misfeasance, bad faith or negligence in the performance of duties or by reason of negligent disregard
of obligations or duties.


 


By
its acceptance of a Certificate, each Certificateholder acknowledges and agrees, by its acceptance of its Certificates, that:
(i) a Directing Holder may have special relationships and interests that conflict with those of Holders of one or more Classes
of Certificates; (ii) a Directing Holder may act solely in its own interests (or, in the case of the Controlling Class Representative,
in the interests of the Holders of the Controlling Class); (iii) a Directing Holder does not have any liability or duties
to the Holders of any Class of Certificates (other than, in the case of the Controlling Class Representative, the Controlling
Class); (iv) a Directing Holder may take actions that favor its own interests (or in the case of the Controlling Class Representative,
the interests of the Holders of the Controlling Class) over the interests of the Holders of one or more other Classes of Certificates;
and (v) a Directing Holder shall have no liability whatsoever (other than, in the case of the Controlling Class Representative,
to a Controlling Class Certificateholder) for having so acted as set forth in clauses (i)-(iv) of this paragraph, and
that no Certificateholder may take any action whatsoever against any Directing Holder or any affiliate, director, officer, employee,
shareholder, member, partner, agent or principal thereof for having so acted; provided, however, that the rights
of a Directing Holder are subject to any related mezzanine intercreditor agreement.

(b)           
Notwithstanding anything to the contrary contained herein:


 


(i)            
after the occurrence and during the continuance of a Control Termination Event, the Controlling Class Representative shall have
no right to consent to any action taken or not taken by any party to this Agreement;


 


(ii)           
after the occurrence and during the continuance of a Control Termination Event, but prior to the occurrence and continuance of
a Consultation Termination Event, the Controlling Class Representative shall remain entitled to receive any notices, reports or
information to which it is entitled pursuant to this Agreement with respect to the applicable Serviced Loan(s) (other than any
Excluded Mortgage Loan), and the Master Servicer, Special Servicer and any other applicable party shall consult with the Controlling
Class Representative in connection with any action to be taken or refrained from taking with respect to the applicable Serviced
Loan(s) (other than any Excluded Mortgage Loan), but only to the extent consultation with, or consent of, the Controlling Class
Representative would have been required under such circumstances prior to the occurrence and continuance of such Control Termination
Event; provided, however, that the Controlling Class Representative shall not be permitted to consult with respect to any
Serviced AB Loan Combination while any related Subordinate Companion Loan Holder is the related Outside Controlling Note Holder;


 


(iii)       
   after the occurrence and during the continuance of a Consultation Termination Event, the Controlling Class
Representative shall have no 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 a Directing Holder; provided that each Controlling Class Certificateholder shall maintain the right to exercise
Voting Rights for the same purposes as any other Certificateholder under this Agreement (other than with respect to Excluded
Controlling Class Mortgage Loans); and


 


(iv)        
  no Person may exercise any of the rights and powers of the Controlling Class Representative with respect to an
Excluded Mortgage Loan.


 


(c)           
Notwithstanding anything to the contrary herein, neither the Master Servicer nor the Special Servicer shall take or refrain from
taking any action pursuant to instructions, directions, objections, advice or consultation from a Directing Holder, Operating
Advisor or a Serviced Companion Loan Holder (or its Companion Loan Holder Representative) that would cause any one of them to
violate applicable law, the terms of any Mortgage Loan or Serviced Loan Combination, the related Loan Documents, this Agreement,
including the Servicing Standard, the related Co-Lender Agreement, any related intercreditor agreement, or the REMIC Provisions
or that would (i) expose any Certificateholder, the Trust Fund, any Mortgage Loan Seller (other than with respect to enforcing
the rights and remedies against such Mortgage Loan Seller pursuant to this Agreement or the related Mortgage Loan Purchase Agreement
with respect to any Material Defect) or any party to this Agreement or their respective Affiliates, officers, directors, employees
or agents to any claim, suit or liability, (ii) materially expand the scope of the Master Servicer’s or the Special

fail to qualify as a grantor trust for federal income tax purposes, or result in the imposition
of a “prohibited transaction” or “prohibited contribution” tax under the REMIC Provisions, or (iv) cause
the Master Servicer or the Special Servicer to act, or fail to act, in a manner that in the reasonable judgment of the Master
Servicer or the Special Servicer, as the case may be, is not in the best interests of the Certificateholders and/or the Serviced
Companion Loan Holders.


 


(d)           
Each Certificateholder and Certificate Owner of a Control Eligible Certificate is hereby deemed to have agreed by virtue of its
purchase of such Certificate (or beneficial ownership interest in such Certificate) to provide its name and address to the Certificate
Administrator and to notify the Certificate Administrator, in writing, of the transfer of any Control Eligible Certificate (or
the beneficial ownership of any Control Eligible Certificate), the selection of a Controlling Class Representative or the
resignation or removal of the Controlling Class Representative. Any such Certificateholder (or Certificate Owner) or its designee
at any time appointed Controlling Class Representative is hereby deemed to have agreed by virtue of its purchase of a Control
Eligible Certificate (or the beneficial ownership interest in a Control Eligible Certificate) to notify the Certificate Administrator
in writing when such Certificateholder (or Certificate Owner) or designee is appointed Controlling Class Representative and
when it is removed or resigns. Upon receipt of any of the notices referred to in the preceding two sentences of this Section
6.09(d), the Certificate Administrator shall promptly notify, in writing, the Special Servicer, the Master Servicer, the Operating
Advisor, the Asset Representations Reviewer and the Trustee of the identity of the Controlling Class Representative, any
resignation or removal of the Controlling Class Representative and/or any new Holder or Certificate Owner of a Control Eligible
Certificate. In addition, upon the request of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer or the Trustee, as applicable, the Certificate Administrator shall provide (on a reasonably prompt basis) the identity
of the then-current Controlling Class and a list of the Certificateholders (or Certificate Owners, if applicable, at the expense
of the Trust if such expense arises in connection with an event as to which the Controlling Class Representative or the Controlling
Class has consent or consultation rights pursuant to this Agreement or in connection with a request made by the Operating Advisor
in connection with its obligation under Section 3.29(d)(ii) of this Agreement to deliver a copy of the Operating Advisor
Annual Report to the Controlling Class Representative, and otherwise at the expense of the requesting party) of the Controlling
Class to such requesting party, and each of the Master Servicer, Special Servicer, Operating Advisor, the Asset Representations
Reviewer and the Trustee shall be entitled to rely on the information so provided by the Certificate Administrator.


 


In
the event of a change in the Controlling Class, the Certificate Administrator shall promptly contact the current Holder(s) (or,
in the case of book-entry Certificates, Certificate Owners) of the Controlling Class (or any designee(s) thereof) or, if known
to the Certificate Administrator, one of its affiliates or, if applicable, any successor Controlling Class Representative or Controlling
Class Certificateholder(s), and determine whether any such entity is the Holder (or Certificate Owner) of at least a majority
of the Controlling Class (in effect after such change in Controlling Class) by Certificate Balance. If at any time the current
Holder of the Controlling Class (or its designee) or, if known to the Certificate Administrator, one of its Affiliates, or any
successor Controlling Class Representative or Controlling Class Certificateholder(s) is no longer the Holder (or Certificate
Owner) of at least a majority of the Controlling Class by Certificate Balance and the Certificate Administrator has neither (i) received
notice of the then-current Controlling Class Certificateholders of at least a majority of the Controlling Class by Certificate


 






    	-376- 



     


    

 


Balance nor (ii) received notice of a replacement Controlling Class Representative pursuant to this Agreement, then a Control
Termination Event and a Consultation Termination Event shall be deemed to have occurred and shall be deemed to continue until
such time as the Certificate Administrator receives any such notice in clauses (i) or (ii).


 


Upon
receipt of notice of a change in Controlling Class Representative, the Certificate Administrator shall promptly forward notice
thereof to each other party to this Agreement.


 


On
the Closing Date, the initial Controlling Class Representative shall deliver (which delivery may be by electronic mail) a certification
substantially in the form of Exhibit M-1H to this Agreement to the Certificate Administrator (who shall promptly forward
such certification to the Master Servicer, the Special Servicer, the Trustee and the Operating Advisor). Upon the resignation
or removal of the existing Controlling Class Representative, any successor Controlling Class Representative shall also deliver
a certification substantially in the form of Exhibit M-1H to this Agreement to the Certificate Administrator (who shall
promptly forward such certification to the Master Servicer, the Special Servicer, the Trustee and the Operating Advisor) prior
to being recognized as the new Controlling Class Representative.


 


(e)            
Once a Controlling Class Representative has been selected, each of the Master Servicer, the Special Servicer, the Operating
Advisor, the Depositor, the Certificate Administrator, the Asset Representations Reviewer, the Trustee and each other Certificateholder
(or Certificate Owner, if applicable) shall be entitled to rely on such selection unless a majority of the Certificateholders
of the Controlling Class, by Certificate Balance, or such Controlling Class Representative shall have notified the Certificate
Administrator, the Master Servicer and each other Certificateholder of the Controlling Class, in writing, of the resignation of
such Controlling Class Representative or the selection of a new Controlling Class Representative. Upon receipt of written
notice of, or other knowledge of, the resignation of a Controlling Class Representative, the Certificate Administrator shall
request the Certificateholders of the Controlling Class to select a new Controlling Class Representative.


 


(f)            
If at any time a book-entry certificate belongs to the Controlling Class, the Certificate Administrator shall notify the related
Certificate Owner or Certificate Owners (through the Depository, unless the Certificate Administrator shall have been previously
provided with the name and address of such Certificate Owner or Certificate Owners) of such event and shall request that it be
informed of any change in the identity of the related Certificate Owner from time to time.


 


(g)           
Until it receives notice to the contrary, each of the Master Servicer, the Special Servicer, the Operating Advisor, the Depositor
and the Trustee and the Certificate Administrator shall be entitled to rely on the most recent notification with respect to the
identity of the Certificateholders of the Controlling Class and the Controlling Class Representative.


 


(h)           
Notwithstanding anything to the contrary contained herein, at any time when the Class E-RR Certificates are the Controlling Class,
the Holder of more than 50% of the Controlling Class (by Certificate Balance) may waive its right to act as or appoint a Controlling
Class Representative and to exercise any of the rights of the Controlling Class Representative or cause the exercise of any of
the rights of the Controlling Class Representative set forth in this Agreement, by irrevocable written notice delivered to the
Depositor, Certificate Administrator,


 






    	-377- 



     


    

 


Trustee, Master Servicer, Special Servicer and Operating Advisor (any such Holder or group
of affiliated Holders that makes such an election, the “Opting-Out Party”). Whenever such waiver by an Opting-Out
Party is in effect, (1) a Control Termination Event and a Consultation Termination Event shall be deemed to have occurred and
be continuing; and (2) the rights of the holder of more than 50% of the Class E-RR Certificates (by Certificate Balance), if the
Class E-RR Certificates are the Controlling Class, to act as or appoint a Controlling Class Representative and the rights of a
Controlling Class Representative will not be operative (notwithstanding whether a Control Termination Event or a Consultation
Termination Event is or would otherwise then be in effect). Any such waiver shall remain effective with respect to such Holder
and such Class until such time as either (x) the Class E-RR Certificates are no longer the Controlling Class or (y) the Opting-Out
Party has (i) sold a majority of the Class E-RR Certificates (by Certificate Balance) to an unaffiliated third party and (ii)
certified to the Depositor, Certificate Administrator, Trustee, Master Servicer, Special Servicer and Operating Advisor that (a)
the Opting-Out Party retains no direct or indirect Voting Rights with respect to the Class E-RR Certificates that it transferred,
(b) there is no voting agreement between the Opting-Out Party and the transferee and (c) the Opting-Out Party retains no direct
or indirect economic interest in the Class E-RR Certificates that it transferred (such sale and certification, a “Class
E-RR Transfer”). Following any such Class E-RR Transfer, and if the Class E-RR Certificates are still the Controlling
Class, the successor holder of more than 50% of the Controlling Class (by Certificate Balance) shall again have the right to act
as or appoint a Controlling Class Representative as set forth herein without regard to any prior waiver by the predecessor Certificateholder.
Such successor Certificateholder shall also have the right as provided in this Section 6.09(h) to irrevocably waive its
right to act as or appoint a Controlling Class Representative or, subject to any such limitations set forth in this Agreement
(including by reason of a Control Termination Event or a Consultation Termination Event otherwise existing), to exercise any of
the rights of the Controlling Class Representative or to cause the exercise of any of the rights of the Controlling Class Representative
as set forth in this Agreement. No successor Certificateholder described above in this paragraph shall have any consent rights
with respect to any Serviced Mortgage Loan that became a Specially Serviced Loan prior to the Class E-RR Transfer and had not
also become a Corrected Loan prior to such Class E-RR Transfer until such Serviced Mortgage Loan becomes a Corrected Loan.

Servicer, as applicable, has commenced to cure such failure within the initial 30-day period and has certified that it has
diligently pursued, and is continuing to pursue, a full cure); or

the Master 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 bankruptcy, insolvency or reorganization statute, make an
assignment for the benefit of its creditors, voluntarily suspend payment of its obligations or take any corporate action in furtherance
of the foregoing; or


 


(viii)         
either of Moody’s or KBRA (or, in the case of Serviced Companion Loan Securities, any Companion Loan Rating Agency) has
(A) qualified, downgraded or withdrawn its rating or ratings of one or more Classes of Certificates or one or more classes
of Serviced Companion Loan Securities, or (B) placed one or more Classes of Certificates or one or more classes of Serviced
Companion Loan Securities on “watch status” in contemplation of rating downgrade or withdrawal and, in the case of

Sub-Servicer appointed by the Master Servicer or the Special Servicer, as applicable, after the Closing Date (but excluding
any Sub-Servicer set forth on Exhibit S), shall (A) for so long as the Trust is subject to the reporting

any applicable notice and cure period to enable the Certificate Administrator or Depositor to comply with the reporting
obligations of the Trust under the Exchange Act or (B) for so long as any Other Securitization Trust is subject to the
reporting requirements of


 






    	-380- 



     


    

 


Regulation AB or the Exchange Act, fail to deliver any Exchange Act reporting
items required to be delivered by such servicer to the related Other Depositor or related Other Exchange Act Reporting Party pursuant
to Article X of this Agreement, in the case of each of clauses (A) and (B), within (a) with respect to the delivery of any item
relating to a Reportable Event, two (2) Business Days of such failure to comply with Article X or (b) with respect to the
delivery of any other item, five (5) Business Days of such failure to comply with Article X (any primary servicer or Sub-Servicer
that defaults in accordance with this Section 7.01(a)(x) shall be terminated at the direction of the Depositor);


 


then,
and in each and every such case, so long as a Servicer Termination Event shall not have been remedied, either (i) the Trustee
may or (ii) upon the written direction to the Trustee from (x) the Holders of at least 25% of the aggregate Voting Rights
of all Certificates or (y) an affected Serviced Companion Loan Holder (but, subject to the next sentence, solely in the case of
the related Serviced Loan Combination and a Servicer Termination Event with respect to the Special Servicer), then the Trustee
shall, terminate the Master Servicer or the Special Servicer, as applicable. Notwithstanding anything to the contrary, it shall
not be a Servicer Termination Event with respect to the pool of Mortgage Loans under clauses (i), (ii), (iii), (iv), (viii)
or (ix) above if the failure, default or event only has an adverse effect on a Serviced Companion Loan, a Serviced Companion Loan
Holder or a rating on any Serviced Companion Loan Securities, but shall be a Servicer Termination Event with respect to the related
Serviced Companion Loan and any related Serviced Companion Loan Holder shall: (i) in the case of any such failure, default
or event on the part of the Master Servicer, have the remedies set forth in Section 7.01(d) with respect to the Servicer
Termination Event with respect to the related Serviced Companion Loan; and (ii) with respect to any such failure, default or event
on the part of the Special Servicer, be able to require termination of the Special Servicer with respect to, but only with respect
to, the related Serviced Loan Combination.


 


In
the event that the Master Servicer is also the Special Servicer and the Master Servicer is terminated as provided in this Section 7.01,
the Master Servicer shall also be terminated as Special Servicer.


 


(b)           
If the Master Servicer receives notice of termination under Section 7.01(c) solely due to a Servicer Termination Event
under Section 7.01(a)(viii) or Section 7.01(a)(ix) and if the Master Servicer to be terminated pursuant to Section
7.01(c) provides the Trustee with the appropriate “request for proposal” materials within five (5) Business
Days following such termination notice, then the Master Servicer shall continue to service as Master Servicer hereunder until
a successor Master Servicer is selected in accordance with this Section 7.01(b). Upon receipt of the “request for
proposal” materials, Trustee shall promptly thereafter (using such “request for proposal” materials provided
by the Master Servicer pursuant to Section 7.01(c)) solicit good faith bids for the rights to service the Mortgage
Loans and the Serviced Loan Combinations under this Agreement from at least three (3) Persons qualified to act as a successor
Master Servicer hereunder in accordance with Section 6.04 (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 that, the Master Servicer shall supply the Trustee with the names of Persons from whom to solicit such bids; and
provided, further, that the Trustee shall not be responsible if less than three (3) or no Qualified Bidders
submit bids for the right to service the Mortgage Loans under this Agreement. The bid proposal shall require any Successful Bidder
(as


 






    	-381- 



     


    

 


defined below), as a condition of such bid, to enter into this Agreement as successor Master Servicer, and to agree to be
bound by the terms hereof, within 45 days after the notice of termination of the Master Servicer. The Trustee shall select the
Qualified Bidder with the highest cash bid (the “Successful Bidder”) to act as successor Master Servicer
hereunder; provided, however, that if the Trustee does not receive a Rating Agency Confirmation from each Rating
Agency within 10 days after the selection of such Successful Bidder, then the Trustee shall repeat the bid process described
above (but subject to the above-described 45-day time period) until such confirmation is obtained. The Trustee shall request
the Successful Bidder to enter into this Agreement as successor Master Servicer pursuant to the terms hereof no later than 45
days after notice of the termination of the Master Servicer.


 


Upon
the assignment and acceptance of master servicing rights hereunder (subject to the terms of Section 3.12 of this Agreement)
to and by the Successful Bidder, the Trustee shall remit or cause to be remitted to the Master Servicer to be terminated pursuant
to Section 7.01(c) of this Agreement, 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).


 


The
Master Servicer to be terminated pursuant to Section 7.01(c) of this Agreement shall be responsible for all out-of-pocket
expenses incurred in connection with the attempt to sell its rights to service the Mortgage Loans and the Serviced Loan Combinations,
which expenses are not reimbursed to the party that incurred such expenses pursuant to the preceding paragraph.


 


If
the Successful Bidder has not entered into this Agreement as successor Master Servicer within the above-described time period
or no Successful Bidder was identified within the above-described time period, the Master Servicer to be terminated pursuant to
Section 7.01(c) shall reimburse the Trustee for all reasonable “out-of-pocket” expenses incurred
by the Trustee in connection with such bid process and the Trustee shall have no further obligations under this Section 7.01(b).
The Trustee thereafter may act or may select a successor to act as Master Servicer hereunder in accordance with Section 7.02.


 


(c)            
In the event that the Master Servicer or the Special Servicer is terminated pursuant to this Section 7.01, the Trustee
shall, by notice in writing to the Master Servicer or the Special Servicer, as the case may be (the “Terminated Party”),
terminate all of its rights and obligations under this Agreement and in and to the Mortgage Loans and Serviced Loan Combination
and the proceeds thereof, other than any rights the Master Servicer or Special Servicer 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, plus interest at the Advance Rate on such amounts until received to the extent such amounts
bear interest as provided in this Agreement, with respect to periods prior to the date of such termination and the right to the
benefits of Section 6.03 and subsection (b) above notwithstanding any such termination). On or after the receipt
by the Terminated Party of such written notice, 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 Mortgage Loans and Serviced Loan Combination or otherwise, shall pass to and be vested in the
Trustee pursuant to and under this


 






    	-382- 



     


    

 


Section and, without limitation, the Trustee 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 Mortgage Loans and Serviced Loan
Combination and related documents, or otherwise. The Master Servicer and the Special Servicer each agrees that, in the event it
is terminated pursuant to this Section 7.01, to promptly (and in any event no later than ten Business Days subsequent
to such notice) provide, at its own expense, the Trustee (or the successor Master Servicer selected by the Trustee pursuant
to Section 7.01(b) of this Agreement or the successor Master Servicer or Special Servicer, as applicable, otherwise appointed
pursuant to Section 7.02 of this Agreement) with all documents and records requested by the Trustee (or the successor
Master Servicer selected by the Trustee pursuant to Section 7.01(b) of this Agreement or the successor Master Servicer
or Special Servicer, as applicable, otherwise appointed pursuant to Section 7.02 of this Agreement) to enable the
Trustee or other successor to its responsibilities hereunder to assume its functions hereunder, and to cooperate with the Trustee
and the successor to its responsibilities hereunder in effecting the termination and transfer of its responsibilities and rights
hereunder, including, without limitation, the transfer to the successor Master Servicer or successor Special Servicer or the Trustee,
as applicable, for administration by it of all cash amounts which shall at the time be or should have been credited by the Master
Servicer or the Special Servicer to the Collection Account, any Loan Combination Custodial Account, any REO Account or Lock-Box
Account shall thereafter be received with respect to the Mortgage Loans and Serviced Loan Combination, and shall promptly provide
the Trustee or such successor Master Servicer or Special Servicer (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 Trustee or such successor
Master Servicer or Special Servicer shall reasonably request (including electromagnetic form), to enable it to assume the Master
Servicer’s or Special Servicer’s function hereunder. All reasonable costs and expenses actually incurred by the Trustee,
the Certificate Administrator or the successor Master Servicer or successor Special Servicer in connection with transferring Mortgage
Files, Servicing Files and related information, records and reports to the successor Master Servicer or Special Servicer and amending
this Agreement to reflect (as well as providing appropriate notices to Mortgagors, ground lessors, insurers and other applicable
third parties regarding) such succession as successor Master Servicer or successor Special Servicer pursuant to this Section 7.01
shall be paid by the predecessor Master Servicer or the Special Servicer, as applicable, upon presentation of reasonable documentation
of such costs and expenses. If the predecessor Master Servicer or Special Servicer (as the case may be) has not reimbursed
the Trustee, the Certificate Administrator or the successor Master Servicer or Special Servicer for such expenses within 90 days
after the presentation of reasonable documentation, such expense shall be reimbursed by the Trust Fund; provided that the
Terminated Party shall not thereby be relieved of its liability for such expenses.


 


(d)           
Notwithstanding Sections 7.01(a) and Section 7.01(c), if (1) any Servicer Termination Event on the part
of the Master Servicer affects a Serviced Companion Loan, the related Serviced Companion Loan Holder or the rating on a class
of the related Serviced Companion Loan Securities and the Master Servicer is not otherwise terminated in accordance with Section 7.01(c),
or (2) a Servicer Termination Event on the part of the Master Servicer occurs that affects only a Serviced Companion Loan, the
related Serviced Companion Loan Holder or the rating on a class of the related Serviced Companion Loan Securities, the Master
Servicer may not


 






    	-383- 



     


    

 


be terminated in accordance with Section 7.01(c), but, at the written direction of the related Serviced
Companion Loan Holder, the Master Servicer shall appoint, within 30 days of such direction, a sub-servicer (or, if the related
Serviced Loan Combination is currently being sub-serviced, to replace, within 30 days of such direction, the then current sub-servicer
with a new sub-servicer). In connection with the Master Servicer’s appointment of any sub-servicer at the direction of a
Serviced Companion Loan Holder in accordance with this Section 7.01(d), the Master Servicer shall obtain a Rating
Agency Confirmation from each Rating Agency. The related sub-servicing agreement shall provide that any sub-servicer appointed
by the Master Servicer at the direction of a Serviced Companion Loan Holder in accordance with this Section 7.01(d)
shall be responsible for all duties, and shall be entitled to all compensation, of the Master Servicer under this Agreement with
respect to the related Serviced Loan Combination, except that the Master Servicer shall be entitled to retain a portion of the
Servicing Fee for the Mortgage Loan that is part of the related Serviced Loan Combination equal to any related Excess Servicing
Fee with respect to such Mortgage Loan (and any related REO Mortgage Loan). Such sub-servicing agreement (a) may be terminated
without cause and without payment of any fee and (b) shall also provide that such sub-servicer shall agree to become the master
servicer under a separate servicing agreement for the applicable Serviced Loan Combination in the event that such Serviced Loan
Combination is no longer to be serviced and administered hereunder, which separate servicing agreement shall contain servicing
and administration, limitation of liability, indemnification and servicing compensation provisions substantially similar to the
corresponding provisions of this Agreement, except for the fact that the applicable Serviced Loan Combination and the related
Mortgaged Properties shall be the sole assets serviced and administered thereunder and the sole source of funds thereunder. If
any sub-servicer appointed by the Master Servicer at the direction of a Serviced Companion Loan Holder in accordance with this
Section 7.01(d) shall at any time resign or be terminated, the Master Servicer shall be required to promptly appoint
a substitute sub-servicer and obtain a Rating Agency Confirmation. In the event a successor Master Servicer is acting hereunder
and that successor Master Servicer desires to terminate the sub-servicer appointed under this Section 7.01(d), the
terminated Master Servicer that was responsible for the Servicer Termination Event that led to the appointment of such sub-servicer
shall be responsible for all costs incurred in connection with such termination, including the payment of any termination fee.


 


(e)            
If the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer has received written notice (which,
for the purposes of this clause (e), shall include any publications by Moody’s, Fitch or KBRA of which the Trustee,
the Certificate Administrator or any Servicing Officer of the Master Servicer, as the case may be, has actual knowledge) from
Moody’s, Fitch or KBRA that the Master Servicer or the Special Servicer no longer is an approved master servicer or approved
special servicer, as applicable, then such party shall promptly notify the others, and the Certificate Administrator shall notify
the related Serviced Companion Loan Holder, to the extent known to the Certificate Administrator, of the same.


 


Section 7.02     
Trustee to Act; Appointment of Successor. On and after the time the Master Servicer or the Special Servicer receives
a notice of termination pursuant to Section 7.01, the Trustee shall, subject to the following provisions of this Section
7.02, be its successor in all respects in its capacity as Master Servicer or Special Servicer 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 Master Servicer or Special Servicer
by the terms and provisions hereof;


 






    	-384- 



     


    

 


provided,
however, that (i) the Trustee shall have no responsibilities, duties, liabilities or obligations with respect to any
act or omission of the Master Servicer or Special Servicer 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 moneys shall not be considered a default by such successor hereunder. The Trustee, as successor Master Servicer
or successor Special Servicer, shall be indemnified to the full extent provided the Master Servicer or Special Servicer, as applicable,
under this Agreement prior to the Master Servicer’s or the Special Servicer’s termination. The appointment of a successor
Master Servicer or successor Special Servicer shall not affect any liability of the predecessor Master Servicer or Special Servicer
which may have arisen prior to its termination as Master Servicer or Special Servicer. The Trustee shall not be liable for any
of the representations, liabilities or warranties of the Master Servicer or Special Servicer herein or in any related document
or agreement, for any acts or omissions of the predecessor Master Servicer or predecessor Special Servicer or for any losses incurred
in respect of any Permitted Investment by the Master Servicer pursuant to Section 3.07 of this Agreement nor shall
the Trustee be required to purchase any Mortgage Loan or Serviced Loan Combination hereunder. As compensation therefor, the Trustee
as successor Master Servicer or successor Special Servicer shall be entitled to the Servicing Fee or Special Servicing Compensation,
as applicable, and all funds relating to the Mortgage Loans and Serviced Companion Loans that accrue after the date of the Trustee’s
succession to which the Master Servicer or Special Servicer would have been entitled if the Master Servicer or Special Servicer,
as applicable, had continued to act hereunder. In the event any Advances made by the Master Servicer and the Trustee shall at
any time be outstanding, or any amounts of interest thereon shall be accrued and unpaid, all amounts available to repay Advances
and interest hereunder shall be applied entirely to the Advances made by the Trustee (and the accrued and unpaid interest thereon),
until such Advances and interest shall have been repaid in full. Notwithstanding the above and subject to Section 6.08,
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 entitled
to at least 25% of the aggregate Voting Rights so request in writing to the Trustee, or if the Rating Agencies do not provide
Rating Agency Confirmations with respect to the Trustee so acting, promptly appoint, or petition a court of competent jurisdiction
to appoint, any established mortgage loan servicing institution for which a Rating Agency Confirmation from each Rating Agency
has been obtained (at the expense of the terminated Master Servicer or Special Servicer, as applicable, or, if the expense is
not so recovered, at the expense of the Trust Fund), as the successor to the Master Servicer or the Special Servicer, as applicable,
hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer or Special
Servicer hereunder; provided that, the related Outside Controlling Note Holder shall have the right to approve a successor
Special Servicer with respect to any Serviced Outside Controlled Loan Combination, and prior to the occurrence and continuance
of a Control Termination Event, the Controlling Class Representative shall have the right to approve a successor Special Servicer
with respect to the other Serviced Loans. No appointment of a successor to the Master Servicer or Special Servicer hereunder shall
be effective until (i) the assumption by such successor of all the Master Servicer’s or Special Servicer’s responsibilities,
duties and liabilities hereunder and (ii) in the case of the appointment of a successor Special Servicer, the Depositor and, if
applicable, each related Other Depositor shall have received the written notice and information with respect to such successor
Special Servicer as set forth in Section 10.02(a). Pending appointment of a successor to the Master Servicer (or the Special
Servicer if the Special Servicer is also the Master Servicer) hereunder, unless the Trustee shall be prohibited by law from
so acting, the Trustee shall act in such capacity as herein above


 






    	-385- 



     


    

 


provided. Pending the appointment of a successor to the Special
Servicer, unless the Master Servicer is also the Special Servicer, the Master Servicer shall act in such capacity. 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 Mortgage Loans and Serviced Companion Loans as it and such successor shall agree; provided, however,
that no such compensation shall be in excess of that permitted the Terminated Party hereunder; provided, further,
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 treated as
Realized Losses; and provided, further that, for so long as no Consultation Termination Event has occurred and is
continuing, the Trustee shall consult with the Controlling Class Representative (and, if a Serviced Outside Controlled Loan Combination
is affected, the Trustee shall consult with the related Outside Controlling Note Holder) prior to the appointment of a successor
to the Terminated Party at such amounts in excess of that permitted the Terminated Party. The Depositor, the Trustee, the Master
Servicer or Special Servicer and such successor shall take such action, consistent with this Agreement, as shall be necessary
to effectuate any such succession.


 


If
the Trustee or an Affiliate acts pursuant to this Section 7.02 as successor to the terminated Master Servicer, it
may reduce the Excess Servicing Fee Rate to the extent that the Trustee’s or such Affiliate’s compensation as successor
Master Servicer would otherwise be below the market rate servicing compensation. If the Trustee elects to appoint a successor
to the terminated Master Servicer other than itself or an Affiliate pursuant to this Section 7.02, it may reduce the
Excess Servicing Fee Rate to the extent reasonably necessary (in the sole discretion of the Trustee) for the Trustee to appoint
a qualified successor Master Servicer that meets the requirements of this Section 7.02.


 


Section 7.03      
Notification to Certificateholders.


 


(a)            
Upon any termination pursuant to Section 7.01 above or appointment of a successor to the Master Servicer or the Special
Servicer, the Certificate Administrator shall give prompt written notice thereof to Certificateholders at their respective addresses
appearing in the Certificate Register, to the Serviced Companion Loan Holders, and electronically, for posting to the Rule 17g-5
Information Provider’s Website pursuant to Section 12.13 of this Agreement, to the Rule 17g-5 Information Provider.


 


(b)           
Within 30 days after the occurrence of any Servicer Termination Event or Operating Advisor Termination Event of which a Responsible
Officer of the Certificate Administrator has actual knowledge, the Certificate Administrator shall transmit by mail to all Holders
of Certificates and any affected Serviced Companion Loan Holder (to the extent the Certificate Administrator has received the
notice information for such Serviced Companion Loan Holder after a request therefor) and electronically, for posting to the Rule
17g-5 Information Provider’s Website pursuant to Section 12.13 of this Agreement, to the Rule 17g-5 Information
Provider notice of such Servicer Termination Event or Operating Advisor Termination Event, unless such Servicer Termination Event
or Operating Advisor Termination Event shall have been cured or waived.


 






    	-386- 



     


    

 


Section 7.04      
Other Remedies of Trustee. During the continuance of any Servicer Termination Event, so long as such Servicer Termination
Event shall not have been remedied, the Trustee, in addition to the rights specified in Section 7.01, 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 Serviced 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 defaulting Master Servicer or Special
Servicer, as applicable. If the Master Servicer or Special Servicer, as applicable, fails to remedy, after the presentation of
reasonable documentation, the Trustee shall be entitled to be reimbursed for such expenses, costs and liability from the Collection
Account or the Loan Combination Custodial Account, as applicable, as provided in Section 3.06 and Section 3.06A
of this Agreement; provided that the Master Servicer or the Special Servicer, as applicable, shall not be relieved
of such liability for such expenses, costs and liabilities. 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 of the Master Servicer or the Special Servicer.


 


Section 7.05     
Waiver of Past Servicer Termination Events and Operating Advisor Termination Events; Termination. The Holders of Certificates
evidencing not less than 66-2/3% of the aggregate Voting Rights of the Certificates (and, if such Servicer Termination Event is
on the part of a Special Servicer, with respect to the related Serviced Loan Combination only, by each affected Serviced Companion
Loan Holder) may, on behalf of all Holders of Certificates, waive any Servicer Termination Event on the part of the Master Servicer,
Special Servicer or any Operating Advisor Termination Event on the part of the Operating Advisor in the performance of its obligations
hereunder and its consequences, except a Servicer Termination Event in connection with making any required deposits (including,
with respect to the Master Servicer, P&I Advances) to or payments from the Collection Account, a Loan Combination Custodial
Account or the Lower-Tier REMIC Distribution Account or in remitting payments as received, in each case in accordance with this
Agreement. Upon any such waiver of a past default, such default shall cease to exist, and any Servicer Termination Event or Operating
Advisor 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 consequent thereon. Any costs and expenses incurred
by the Certificate Administrator in connection with such default and prior to such waiver shall be reimbursed by the Master Servicer,
the Special Servicer or the Operating Advisor, as applicable, promptly upon demand therefor and if not reimbursed to the Certificate
Administrator within 90 days of such demand, from the Trust Fund; provided that the Trust Fund shall be reimbursed
by the Master Servicer, the Special Servicer or the Operating Advisor, as applicable, to the extent such amounts are reimbursed
to the Certificate Administrator from the Trust Fund. Notwithstanding the foregoing, (a) a Servicer Termination Event under
any of Section 7.01(a)(i) and Section 7.01(a)(ii) of this Agreement may be waived only by all of the Certificateholders
of the affected Classes, and (b) a Servicer Termination Event under Section 7.01(a)(x) of this Agreement may
be waived only with the consent of the Depositor, together with (in the case of each of clauses (a) and (b) of this sentence)


 






    	-387- 



     


    

 


the consent of each Serviced Companion Loan Holder, if any, that
is affected by such Servicer Termination Event.


 


The
foregoing paragraph notwithstanding, if the Holders representing at least the requisite percentage of the Voting Rights allocated
to each affected Class of Certificates desire to waive a Servicer Termination Event by the Master Servicer, but a Serviced Companion
Loan Holder related to a Serviced Loan Combination (if adversely affected thereby) does not wish to waive that Servicer Termination
Event, then those Certificateholders may still waive that Servicer Termination Event, and the applicable Serviced Companion Loan
Holder will be entitled to require that the Master Servicer appoint, within 60 days of the applicable Serviced Companion Loan
Holder’s request, a sub-servicer (or, if the applicable Serviced Loan Combination is currently being subserviced, to replace,
within 60 days of the applicable Serviced Companion Loan Holder’s request, the then current sub-servicer with a new
sub-servicer) with respect to the applicable Serviced Loan Combination. In connection with the Master Servicer’s appointment
of a sub-servicer at the request of a Serviced Companion Loan Holder in accordance with this Section 7.05, the Master
Servicer shall obtain a Rating Agency Confirmation from each Rating Agency at the expense of the Serviced Companion Loan Holder.
The related sub-servicing agreement shall provide that any sub-servicer appointed by the Master Servicer at the request of a Serviced
Companion Loan Holder in accordance with this Section 7.05 shall be responsible for all duties, and shall be entitled
to all compensation , of the Master Servicer under this Agreement with respect to the applicable Serviced Loan Combination, except
that the Master Servicer shall be entitled to retain a portion of the Servicing Fee for the related Mortgage Loan equal to any
related Excess Servicing Fee. Such Sub-Servicing Agreement (a) may be terminated without cause and without the payment of
any fee and (b) shall also provide that such sub-servicer shall become the master servicer under a separate servicing agreement
for the applicable Serviced Loan Combination in the event that the Serviced Loan Combination is no longer to be serviced and administered
hereunder, which separate servicing agreement shall contain servicing and administration, limitation of liability, indemnification
and servicing compensation provisions substantially similar to the corresponding provisions of this Agreement, except for the
fact that the applicable Serviced Loan Combination and the related Mortgaged Properties shall be the sole assets serviced and
administered thereunder and the sole source of funds thereunder. Such sub-servicer (a) may be terminated without cause and
without the payment of any fee and (b) shall meet the requirements of Section 3.01 of this Agreement. If any
sub-servicer appointed by the Master Servicer at the request of a Serviced Companion Loan Holder in accordance with this Section 7.05
shall at any time resign or be terminated, the Master Servicer shall be required to promptly appoint a substitute sub-servicer
with respect to which a Rating Agency Confirmation has been obtained at the expense of the applicable resigning or terminated
sub-servicer (and any applicable Sub-Servicing Agreement shall so provide), and if the resigning or terminated sub-servicer fails
to cover such expense, the Master Servicer shall do so. In the event a successor Master Servicer is acting hereunder and that
successor Master Servicer desires to terminate the sub-servicer appointed under this Section 7.05, the terminated
Master Servicer that was responsible for the Servicer Termination Event that led to the appointment of such sub-servicer shall
be responsible for all costs incurred in connection with such termination, including the payment of any termination fee.

Section 7.06      
Termination of the Operating Advisor.


 


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


 


(i)           
any failure by the Operating Advisor to observe or perform in any material respect any 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 Operating Advisor by the Trustee or to the
Operating Advisor and the Trustee by the Holders of Certificates having greater than 25% of the aggregate Voting Rights of all
then outstanding Certificates; provided, however, that with respect to any such failure which is not curable within
such 30-day period, the Operating Advisor shall have an additional cure period of thirty (30) days to effect such cure so long
as it has commenced to cure such failure with the initial 30-day period and has provided the Trustee and the Certificate Administrator
with an Officer’s Certificate certifying that it has diligently pursued, and is continuing to pursue, such cure;


 


(ii)           
any failure by the Operating Advisor to perform its obligations set forth in this Agreement in accordance with the Operating Advisor
Standard which failure shall continue unremedied for a period of 30 days after the date on which written notice of such failure
is given to the Operating Advisor by any party to this Agreement;


 


(iii)      
    any failure by the Operating Advisor to be an Eligible Operating Advisor, which failure shall continue
unremedied for a period of 30 days;


 


(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 Operating Advisor, and such decree or order shall
have remained in force undischarged or unstayed for a period of 60 days;


 


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


 


(vi)         
the Operating Advisor 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.


 






    	-389- 



     


    

 


Upon
receipt by the Certificate Administrator of notice of the occurrence of any Operating Advisor Termination Event, the Certificate
Administrator shall promptly provide written notice to all Certificateholders by posting such notice on its internet website,
unless the Certificate Administrator has received notice that it has been remedied. If an Operating Advisor Termination Event
shall occur then, and in each and every such case, so long as such Operating Advisor Termination Event shall not have been remedied,
either the Trustee (i) may or (ii) upon the written direction of holders of Certificates evidencing not less than 25%
of the Voting Rights of each Class of Non-Reduced Certificates, the Trustee shall, terminate all of the rights and obligations
of the Operating Advisor under this Agreement, other than rights and obligations accrued prior to such termination (including
the right to receive all amounts accrued and owing to it under this Agreement) and other than indemnification rights (arising
out of events occurring prior to such termination), by notice in writing to the Operating Advisor. Notwithstanding anything herein
to the contrary, the Depositor shall have the right, but not the obligation, to notify the Certificate Administrator and the Trustee
of any Operating Advisor Termination Event of which the Depositor becomes aware.


 


(b)           
Upon (i) the written direction of Holders of Certificates evidencing not less than 15% of the Voting Rights of the Non-Reduced
Certificates requesting a vote to terminate and replace the Operating Advisor with a proposed successor Operating Advisor that
is an Eligible Operating Advisor and (ii) payment by such Holders to the Certificate Administrator of the reasonable fees
and expenses to be incurred by the Certificate Administrator in connection with administering such vote, the Certificate Administrator
shall promptly provide written notice of the requested vote to the Operating Advisor and to all Certificateholders by (i) posting
such notice on its internet website, and (ii) mailing such notice to all Certificateholders at their addresses appearing
in the Certificate Register and to the Operating Advisor. Upon the affirmative vote of the Holders of Certificates evidencing
more than 50% of the Voting Rights allocable to the Non-Reduced Certificates of those Holders that exercise their right to vote
(provided that Holders entitled to exercise at least 50% of the Voting Rights allocable to the Non-Reduced Certificates
exercise their right to vote within 180 days of the initial request for a vote (which, for the avoidance of doubt, is the date
on which the aforementioned notice was mailed to the Certificateholders)), the Trustee shall terminate all of the rights and obligations
of the Operating Advisor under this Agreement by notice in writing to the Operating Advisor. The provisions set forth in the foregoing
sentences of this Section 7.06(b) shall be binding upon and inure to the benefit of solely the Certificateholders
and the Trustee as between each other. The Operating Advisor shall not have any cause of action based upon or arising from any
breach or alleged breach of such provisions. As between the Operating Advisor, 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 Operating Advisor. The Certificate Administrator shall include on each Distribution Date Statement a statement that each
Certificateholder and Certificate Owner may access notices on the Certificate Administrator’s Website and each Certificateholder
and Certificate Owner may register to receive e-mail notifications when such notices are posted on the Certificate Administrator’s
Website; provided that the Certificate Administrator shall be entitled to reimbursement from the requesting Certificateholders
for the reasonable expenses of posting such notices.


 


(c)            
On or after the receipt by the Operating Advisor of such written notice of termination, subject to the foregoing, all of its authority
and power under this Agreement shall be


 






    	-390- 



     


    

 


terminated and, without limitation, the terminated Operating Advisor shall execute any
and all documents and other instruments, and do or accomplish all other acts or things reasonably necessary or appropriate to
effect the purposes of such notice of termination. As soon as practicable, but in no event later than 15 Business Days after (1)
the Operating Advisor resigns pursuant to Section 6.04 of this Agreement (excluding resignation under the circumstances
contemplated in Section 6.04(d) where no successor Operating Advisor is required to be appointed) or (2) the Trustee delivers
such written notice of termination to the Operating Advisor, the Trustee shall appoint a successor Operating Advisor that is an
Eligible Operating Advisor. The Trustee shall provide written notice of the appointment of a successor Operating Advisor to the
Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator, the Depositor, any related Outside
Controlling Note Holder and, if a Consultation Termination Event does not exist, the Controlling Class Representative within one
Business Day of such appointment, and the Certificate Administrator shall provide written notice of such appointment to each Certificateholder
within one Business Day of the receipt of such notice of appointment from the Trustee. Except as contemplated by Section 7.06(b)
of this Agreement, the appointment of a successor Operating Advisor shall not be subject to the vote, consent or approval
of the holder of any Class of Certificates.


 


The
Operating Advisor shall not at any time be the Depositor, the Master Servicer, the Special Servicer, a Sponsor or an Affiliate
of any of them. If any of such entities becomes the Operating Advisor, including by means of an Affiliation arising after the
date hereof, the Operating Advisor shall immediately resign or cause an assignment under Section 6.04 of this Agreement
and the Trustee shall appoint a successor Operating Advisor subject to and in accordance with this Section 7.06(c),
which successor Operating Advisor may be an Affiliate of the Trustee. Notwithstanding the foregoing, if the Trustee is unable
to find a successor Operating Advisor within 30 days of the termination of the Operating Advisor, the Depositor shall be
permitted to find a replacement. Unless and until a replacement Operating Advisor is appointed, no party shall act as the Operating
Advisor and the provisions in this Agreement relating to consultation with respect to the Operating Advisor shall not be applicable
until a replacement Operating Advisor is appointed hereunder.


 


(d)           
Upon any resignation or termination of the Operating Advisor and, if applicable, appointment of a successor to the Operating Advisor,
the Trustee shall, as soon as possible, give written notice thereof to the Special Servicer, the Master Servicer, the Certificate
Administrator (who shall, as soon as possible, give written notice thereof to the Certificateholders), the Depositor, any related
Outside Controlling Note Holder, the Controlling Class Representative (if a Consultation Termination Event does not exist) and,
for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section 12.13 of this Agreement, the
Rule 17g-5 Information Provider. In the event that the Operating Advisor resigns or is terminated, all of its rights and obligations
under this Agreement shall terminate, other than any rights or obligations that accrued prior to the date of such resignation
or termination (including the right to receive all amounts accrued and owing to it under this Agreement) and other than any rights
to indemnification arising out of events occurring prior to such resignation or termination.

Duties of the Trustee and the Certificate Administrator.


 


(a)            
The Trustee, prior to the occurrence of a Servicer Termination Event of which a Responsible Officer of the Trustee has actual
knowledge and after the curing or waiver of all Servicer Termination Events which may have occurred, undertakes to perform such
duties and only such duties as are specifically set forth in this Agreement and no permissive right of the Trustee shall be construed
as a duty. During the continuance of a Servicer Termination Event of which a Responsible Officer of the Trustee has actual knowledge,
the Trustee, subject to the provisions of Section 7.02 and Section 7.04 of this Agreement, shall exercise
such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in its exercise, as a
prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. The Certificate
Administrator undertakes to perform at all times such duties and only such duties as are specifically set forth in this Agreement
and no permissive right of the Certificate Administrator shall be construed as a duty.


 


(b)           
Each of the Trustee and the Certificate Administrator, upon receipt of any resolutions, certificates, statements, opinions, reports,
documents, orders or other instruments furnished to the Trustee or the Certificate Administrator, as applicable, which are specifically
required to be furnished pursuant to any provision of this Agreement (other than the Mortgage Files, the review of which is specifically
governed by the terms of Article II, the Diligence Files, any CREFC® reports and any information delivered for posting
to the Certificate Administrator’s Website or the Rule 17g-5 Information Provider’s Website), shall examine them to
determine whether they conform on their face to the requirements of this Agreement to the extent specifically set forth herein;
provided, however, that neither the Trustee nor the Certificate Administrator shall be responsible for the accuracy
or content of any such resolution, certificate, statement, opinion, report, document, order or other instrument provided to it
hereunder if accepted in good faith. If any such instrument is found not to conform on its face to the requirements of this Agreement
in a material manner, the Trustee or the Certificate Administrator, as applicable, shall request a corrected instrument, and if
the instrument is not corrected to the Trustee’s or the Certificate Administrator’s, as applicable, reasonable satisfaction,
the Certificate Administrator (if the Certificate Administrator requested the corrected instrument or upon direction from the
Trustee if the Trustee requested the corrected instrument) will provide notice thereof to the Certificateholders.


 


(c)            
Neither the Trustee, the Certificate Administrator nor any of their respective officers, directors, employees, agents or “control”
persons within the meaning of the Act shall have any liability arising out of or in connection with this Agreement, provided
that, subject to Section 8.02 of this Agreement, no provision of this Agreement shall be construed to relieve
the Trustee or the Certificate Administrator, as applicable, or any such person, from liability for its


 






    	-392- 



     


    

 


own negligent action,
its own negligent failure to act or its own willful misconduct or its own bad faith; and provided, further, that:


 


(i)    
        Prior to the occurrence of a Servicer Termination Event or Operating Advisor Termination Event
of which a Responsible Officer of the Trustee has actual knowledge, and after the curing or waiver of all such Servicer
Termination Events which may have occurred, the duties and obligations of the Trustee shall be determined solely by the
express provisions of this Agreement, neither the Trustee nor the Certificate Administrator shall be liable except for the
performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or
obligations shall be read into this Agreement against the Trustee or the Certificate Administrator and, in the absence of bad
faith on the part of the Trustee or the Certificate Administrator, the Trustee or the Certificate Administrator, as
applicable, may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein,
upon any resolutions, certificates, statements, reports, opinions, documents, orders or other instruments furnished to the
Trustee or the Certificate Administrator, as applicable, that conform on their face to the requirements of this Agreement
without responsibility for investigating the contents thereof;


 


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


 


(iii)    
      Neither the Trustee nor the Certificate Administrator shall be personally liable with respect
to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of Holders of
Certificates entitled to greater than 50% of the Percentage Interests (or such other percentage as is specified herein for
such action) of each affected Class, or of the aggregate Voting Rights of the Certificates, relating to the time, method and
place of conducting any proceeding for any remedy available to the Trustee or the Certificate Administrator, as applicable,
or exercising any trust or power conferred upon the Trustee or the Certificate Administrator, as applicable, under this
Agreement;


 


(iv)     
     Neither the Trustee, the Certificate Administrator nor any of their respective directors, officers,
employees, agents or control persons shall be responsible for any act or omission of any Custodian, Paying Agent or
Certificate Registrar that is not the same Person as, or an Affiliate of, the Trustee or the Certificate Administrator, as
applicable, and that is selected other than by the Trustee or the Certificate Administrator, as applicable, performed or
omitted in compliance with any custodial or other agreement, or any act or omission of the Master Servicer, Special Servicer,
the Depositor, the Operating Advisor, any Serviced Companion Loan Holder, the Directing Holder or the Controlling Class
Representative or any other third Person, including, without limitation, in connection with actions taken pursuant to this
Agreement;


 


(v)     
      Neither the Trustee nor the Certificate Administrator shall be under any obligation to appear
in, prosecute or defend any legal action unless such action is incidental


 






    	-393- 



     


    

 


to its respective duties as Trustee or Certificate Administrator, as applicable, in accordance
with this Agreement (and, if it does, all reasonable legal expenses and costs of such action shall be expenses and costs of the
Trust Fund) and in its opinion does not expose it to any expense or liability for which reimbursement is not reasonably assured,
and the Trustee or the Certificate Administrator, as applicable, shall be entitled to be reimbursed therefor from the Collection
Account, unless such legal action arises (i) as a result of any willful misconduct, bad faith, fraud or negligence in the
performance of duties of the Trustee or the Certificate Administrator, as the case may be, or by reason of negligent disregard
of the Trustee’s or the Certificate Administrator’s, as the case may be, obligations or duties hereunder, or (ii) as
a result of the breach by the Trustee or the Certificate Administrator, as the case may be, of any of its representations or warranties

of the Trustee and the Certificate Administrator may consult with counsel and the written 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

(iii)
 (A)Neither the Trustee nor the Certificate Administrator shall be under any obligation to institute, conduct
or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders,

Administrator, as applicable, security or indemnity reasonably satisfactory to the Trustee or the Certificate Administrator, as
applicable, against the costs, expenses and liabilities which may be incurred therein or thereby; and


 


   (B)       the

be
answerable for other than its negligence or willful misconduct in the performance of any such act;


 


provided
that subject to the foregoing clause (A), nothing contained herein shall relieve the Trustee of the obligations, upon
the occurrence of a Servicer Termination Event (which has not been cured or waived) of which a Responsible Officer of the Trustee
has actual knowledge, to exercise such of the rights and powers vested in it by this Agreement, and to use the same degree of
care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs;


 


(iv)       Neither
the Trustee, the Certificate Administrator nor any of their respective directors, officers, employees, Affiliates, agents or “control”

as is specified herein) of the Percentage Interests of any affected Class; provided, however, that if the payment
within a reasonable time to the Trustee or the Certificate Administrator, as applicable, of the costs, expenses or liabilities
likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee or the Certificate Administrator,
as applicable, not reasonably assured to the Trustee or the Certificate Administrator, as applicable, by the security afforded
to it by the terms of this Agreement, the Trustee or the Certificate Administrator, as applicable, may require reasonable indemnity
against such expense or liability as a condition to taking any such action. The reasonable expense of every such investigation
shall be paid by the Master Servicer, the Special Servicer or the Operating Advisor, as applicable, if a Servicer Termination
Event or Operating Advisor Termination Event shall have occurred and be continuing relating to the Master Servicer, the Special
Servicer or the Operating Advisor, respectively and if such investigation results from such Servicer Termination Event or Operating
Advisor Termination Event, and otherwise by the Certificateholders requesting the investigation;


 


(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 but shall not be relieved of its obligations hereunder; and

contribution
of assets to the Trust Fund unless the Trustee or the Certificate Administrator, as applicable, shall have received an Opinion
of Counsel (the costs of obtaining such opinion to be borne by the Person requesting such contribution) to the effect that the
inclusion of such assets in the Trust Fund will not cause either Trust REMIC to fail to qualify as a REMIC or cause the Grantor
Trust to fail to qualify as a grantor trust, at any time that any Certificates are outstanding or subject a Trust REMIC to any
tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances.


 


(c)       All
rights of action under this Agreement or under any of the Certificates, enforceable by the Trustee or the Certificate Administrator,
as applicable, may be enforced by it 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 shall be brought in its
name for the benefit of all the Holders of such Certificates, subject to the provisions of this Agreement.

be included in the first secure e-mail sent by the Trustee or the Certificate Administrator, as applicable, to the E-mail Recipient.


 


(g)       No
provision of this Agreement or any Loan Document shall be deemed to impose any duty or obligation on the Trustee or the Certificate
Administrator to take or omit to take any action, or suffer any action to be taken or omitted, in the performance of its duties
or obligations under the Loan Documents, or to exercise any right or power thereunder, to the extent that taking or omitting to
take such action or suffering such action to be taken or omitted would violate applicable law binding upon it (which determination
may be based on Opinion of Counsel).

set forth in this Agreement. 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 the sale of such Certificates, or for the use

the Trustee or the Certificate Administrator, each, in its individual capacity or any other capacity, may become the owner or

that, subject to Section 8.01 and Section 8.02 of this Agreement, neither the Trustee nor the Certificate

party hereto and each Rating Agency in connection with its termination or removal; provided that if the Trustee or the

of the Voting Rights of all Certificates as provided in the immediately preceding paragraph, then such Holders will be required
to pay all the reasonable costs and expenses of the Trustee or the Certificate Administrator, as applicable, necessary to effect
the transfer of the rights and obligations (including, if applicable, custody of any Mortgage Files in its possession) of the
Trustee or Certificate Administrator, as applicable, to a successor trustee or certificate administrator.

the Trustee without cause, recorded as appropriate) to such successor, and such successor shall review the documents delivered
to it or the Custodian with respect to each Mortgage Loan, and certify in writing that, as to each Mortgage Loan then subject
to this Agreement, such endorsement and assignment has been made. The outgoing Trustee shall provide copies of the documentation
provided for in items (A) and (B) above to the Master Servicer, in each case to the extent such copies are not already in the
Master Servicer’s possession. If the Trustee is removed without cause, the Loan Documents identified in clause (B)

or removal of the predecessor Trustee or Certificate Administrator, as applicable, shall become effective and such successor Trustee
or Certificate Administrator, as applicable, without any further act, deed or conveyance, shall become fully vested with all the

    	-405- 



     


    

 


no
event may the Operating Advisor, the Asset Representations Reviewer or any of their Affiliates be appointed as successor Trustee
or successor Certificate Administrator.


 


Upon

the Depositor shall mail notice of the succession of such Trustee or Certificate Administrator, as applicable, hereunder to all
Holders of Certificates at their addresses as shown in the Certificate Register and to the Companion Loan Holders. If the Depositor

the successor Trustee or Certificate Administrator, as applicable, shall cause such notice to be mailed at the expense of the
Depositor.


 


(b)       Any
successor Trustee or Certificate Administrator appointed pursuant to this Agreement shall satisfy the eligibility requirements
set forth in Section 8.06 hereof.


 


Section 8.09          Merger
or Consolidation of the Trustee or the Certificate Administrator. Any entity into which the Trustee or the Certificate
Administrator may be merged or converted, or with which the Trustee or the Certificate Administrator, as applicable, may be consolidated,
or any entity resulting from any merger, conversion or consolidation to which the Trustee or the Certificate Administrator, as
applicable, shall be a party, or any entity succeeding to the corporate trust business of the Trustee or the Certificate Administrator,
as applicable, shall be the successor of the Trustee or the Certificate Administrator, as applicable, hereunder, provided such
entity shall be eligible under the provisions of Section 8.06 without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.


 


Section 8.10          Appointment
of Co-Trustee or Separate Trustee. Notwithstanding any other provisions hereof, at any time, for the purpose of meeting
any legal requirements of any jurisdiction in which any part of the Trust Fund, the assets thereof or any property securing the
same may at the time be located, the Depositor and the Trustee acting jointly shall have the power and shall execute and deliver
all instruments to appoint one or more Persons to act (at the expense of (i) the Trustee, if the need to appoint such co-trustee(s)
arises from any change in or matter relating to the identity, organization, status, power, conflicts, internal policy or other
development or matter with respect to the Trustee, and/or (ii) the Trust Fund, if the need to appoint such co-trustee(s) arises
from a change in applicable law or the identity, status or power of the Trust Fund; provided, however, that in the
event the need to appoint such co-trustee(s) arises from a combination of the events described in clause (i) and clause
(ii), the expense shall be split evenly between the Trustee and the Trust Fund; and provided, further, that in the
event the need to appoint such co-trustee(s) arises from none of the events described in clause (i) and clause (ii), such appointment
shall be at the expense of the Trust Fund) as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or
separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity, such title to
the Trust Fund, or any part thereof, and, subject to the other provisions of this Section 8.10, such powers, duties,
obligations, rights and trusts as the Depositor and the Trustee may consider necessary or desirable. If the Depositor shall not
be in existence or shall not have joined in such appointment within 15 days after the receipt by it of a request so to do, or
in case a Servicer Termination Event shall have occurred and be continuing, the Trustee alone shall have the power to make such
appointment. Except as required by applicable law, the appointment of a co-trustee or separate trustee shall not relieve the Trustee


 






    	-406- 



     


    

 


of
its responsibilities, obligations and liabilities hereunder. No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor Trustee under Section 8.06 hereunder and no notice to Holders of Certificates
of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08 hereof.


 


In
the case of any appointment of a co-trustee or separate trustee pursuant to this Section 8.10, all rights, powers,
duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by
the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not
authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction
in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer hereunder),
the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to the Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and
performed by such separate trustee or co-trustee solely at the direction of the Trustee.


 


The
Depositor and the Trustee acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee,
or if the separate trustee or co-trustee is an employee of the Trustee, the Trustee acting alone may accept the resignation of
or remove any separate trustee or co-trustee.


 


Any
notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees
and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall
refer to this Agreement and the conditions of this Article VIII. Every such instrument shall be filed with the Trustee.
Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property
specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject
to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of,
affecting the liability of, or affording protection to, the Trustee. In no event shall any such separate trustee or co-trustee
be entitled to any provision relating to the conduct of, affecting the liability of, or affording protection to, such separate
trustee or co-trustee that imposes a standard of conduct less stringent than that imposed on the Trustee hereunder, affording
greater protection than that afforded to the Trustee hereunder or providing a greater limit on liability than that provided to
the Trustee hereunder.


 


Any
separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority,
to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name.
If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties,
rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment
of a new or successor trustee.

the Asset Representations Reviewer, the Certificate Administrator and the Trustee created hereby with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices

the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer,


 






    	-409- 



     


    

 


the
Master Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein)
then included in the Trust Fund pursuant to subsection (c), (ii) the exchange by the Remaining Certificateholder of
its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to subsection (h) and (iii) the final payment or other liquidation (or any advance with respect thereto) of the last
Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided, however, that in no event
shall the trust created hereby continue beyond the expiration of twenty-one years from the death of the last survivor of the descendants
of Joseph P. Kennedy, the late ambassador of the United States to the United Kingdom, living on the date hereof. All such payments
as contemplated by the preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer,
as applicable, promptly following receipt thereof.


 


(b)       In
connection with a termination contemplated by Section 9.01(a) of this Agreement, the Trust REMICs outstanding shall
be terminated and the assets of the Lower-Tier REMIC shall be sold or otherwise disposed of in connection therewith, pursuant
to a “plan of complete liquidation” within the meaning of Code Section 860F(a)(4)(A) providing for the actions
contemplated by the provisions hereof pursuant to which the applicable Notice of Termination is given and requiring that the assets
of the Lower-Tier REMIC shall be sold for cash and that each such Trust REMIC shall terminate on a Distribution Date occurring
not more than 90 days following the date of adoption of the plan of complete liquidation. For purposes of this Section 9.01(b),
the Notice of Termination given pursuant to Section 9.01(c) shall constitute the adoption of the plan of complete
liquidation as of the date such notice is given, which date shall be specified by the Certificate Administrator in the final federal
income tax returns of each Trust REMIC. Notwithstanding the termination of the Trust REMICs, or the Trust Fund, the Certificate
Administrator shall be responsible for filing the final Tax Returns for the Trust REMICs and for the Grantor Trust for the period
ending with such termination, and shall maintain books and records with respect to the Trust REMICs and the Grantor Trust for
the period for which it maintains its own tax returns or other reasonable period.


 


(c)       The
Holders of the Controlling Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if
such Holders do not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if
none of such Holders, the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing
greater than a 50% Percentage Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than
30 days’ prior notice given to the parties (or, if applicable, the other parties) to this Agreement (whereupon the Master
Servicer shall notify the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the
Anticipated Termination Date, by purchasing on such date all, but not less than all, of the Mortgage Loans (and in the case of
the Serviced Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for in the related
Co-Lender Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the
Trust Fund’s interest in any REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any
Mortgage Loan then included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the
Termination Purchase Amount and (B) the reasonable out-of-pocket expenses of the Master Servicer (unless the Master Servicer
is the purchaser of such Mortgage Loans), the Special Servicer (unless the Special


 






    	-410- 



     


    

 


Servicer
is the purchaser of such Mortgage Loans), the Trustee and the Certificate Administrator, as applicable, with respect to such termination,
minus (ii) solely in the case where the Master Servicer or the Special Servicer is effecting such purchase, the aggregate
amount of unreimbursed Advances, if any, made by the Master Servicer or Special Servicer, as applicable, together with any interest
accrued and payable to the Master Servicer or the Special Servicer, as applicable, in respect of such Advances and any unpaid
Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding (which items will be deemed to have been paid or
reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection with such purchase).


 


Any
Person(s) effecting an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling
Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate,
notify the Certificate Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder)
of its intention to do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred
by any and all parties to this Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other
assets of the Trust Fund pursuant to this Section 9.01(c) shall be borne by the party exercising its purchase
rights hereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an Appraiser
pursuant to this subsection (c).


 


(d)       If
the Trust Fund has not been previously terminated pursuant to subsection (c) or subsection (h) of this Section 9.01,
the Certificate Administrator shall determine as soon as practicable the Distribution Date on which the Certificate Administrator
reasonably anticipates, based on information with respect to the Mortgage Loans previously provided to it, that the final distribution
will be made (i) to the Holders of outstanding Regular Certificates and to the Certificate Administrator in respect of the
Lower-Tier Regular Interests, notwithstanding that such distribution may be insufficient to distribute in full an amount equal
to the remaining Certificate Balance or Lower-Tier Principal Balance, as applicable, of each such Class of Certificates and Lower-Tier
Regular Interest, together with amounts required to be distributed on such Distribution Date pursuant to Section 4.01
of this Agreement (or, if the Regular Certificates are no longer outstanding, to the Holders of the Class R Certificates)
and (ii) to the Holders of the Grantor Trust Certificates, of any amount remaining in the Collection Account, the Lower-Tier REMIC
Distribution Account, the Upper-Tier REMIC Distribution Account, the Excess Interest Distribution Account and/or the Excess Liquidation
Proceeds Reserve Account, as applicable, in any case, following the later to occur of (a) the receipt or collection of the
last payment due on any Mortgage Loan included in the Trust Fund or (b) the liquidation or disposition pursuant to Section 3.17
of this Agreement of the last asset held by the Trust Fund.


 


(e)       Notice
of any termination of the Trust Fund pursuant to this Section 9.01 shall be mailed by the Certificate Administrator
to affected Certificateholders at their addresses shown in the Certificate Register (with a copy to the Master Servicer, the Special
Servicer and, for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section 12.13 of this
Agreement, the Rule 17g-5 Information Provider) as soon as practicable after the Certificate Administrator shall have received,
given or been deemed to have received a Notice of Termination but in any event not more than thirty days, and not less than ten
days, prior to the Anticipated Termination Date. The notice mailed by the Certificate Administrator to affected Certificateholders
shall:


 






    	-411- 



     


    

 


(i)       specify
the Anticipated Termination Date on which the final distribution is anticipated to be made to Holders of Certificates of the Classes
specified therein;


 


(ii)       specify
the amount of any such final distribution, if known; and


 


(iii)       state
that the final distribution to Certificateholders will be made only upon presentation and surrender of Certificates at the office
of the Paying Agent therein specified.


 


If
the Trust Fund is not terminated on any Anticipated Termination Date for any reason, the Certificate Administrator shall promptly
mail notice thereof to each affected Certificateholder.


 


(f)       Any
funds not distributed on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall
be set aside and held in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall
terminate. If any Certificates as to which notice of the Termination Date has been given pursuant to this Section 9.01
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 Certificateholders, at their last addresses shown in the Certificate
Register, to surrender their Certificates for cancellation in order to receive, from such funds held, the final distribution with
respect thereto. If within one year after the second notice any Certificate shall not have been surrendered for cancellation,
the Certificate Administrator may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders
concerning surrender of their Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders
shall be paid out of the assets which remain held. Subject to applicable state law with respect to escheatment of funds, if within
two years after the second notice any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay
to the Class R Certificateholders all amounts distributable to the Holders thereof. No interest shall accrue or be payable
to any Certificateholder on any amount held as a result of such Certificateholder’s failure to surrender its Certificate(s) for
final payment thereof in accordance with this Section 9.01.


 


(g)       For
purposes of this Section 9.01, the Remaining Certificateholder shall have the first option to terminate the Trust
Fund pursuant to subsection (h), and then the Holders of the Controlling Class representing more than 50% of the Certificate Balance
of the Controlling Class, and then the Special Servicer, and then the Master Servicer, and then the Holders of Class R Certificates
representing more than 50% of the Percentage Interests in such Class, in each of the last four cases, pursuant to subsection (c).


 


(h)       Following
the date on which the Class X-A Notional Amount, the Class X-B Notional Amount, the Class X-D Notional Amount and the
aggregate Certificate Balance of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB, Class A-S,
Class B, Class C and Class D Certificates are reduced to zero, the Remaining Certificateholder shall have the right to exchange
all of its Certificates (but excluding the Class S and Class R Certificates) for all of the Mortgage Loans and each
REO Property (and including the Trust Fund’s interest in any REO Property acquired with respect to the Outside Serviced
Mortgage Loans) remaining in the Trust Fund as contemplated by clause (ii) of Section 9.01(a) by giving

Remaining
Certificateholder shall pay the Master Servicer an amount equal to (i) the product of (A) the Prime Rate, (B) the
aggregate Certificate Balance of the then-outstanding Principal Balance Certificates as of the day of the exchange and (C) three,
divided by (ii) 360. In the event that the Remaining Certificateholder elects to exchange all of the Certificates (other
than the Class S and Class R Certificates) for all of the Mortgage Loans and each REO Property (and including the Trust Fund’s
interest in any REO Property acquired with respect to the Outside Serviced Mortgage Loans) remaining in the Trust Fund in accordance
with the preceding sentence, such Remaining Certificateholder, not later than the Termination Date, shall deposit in the Collection
Account an amount in immediately available funds equal to all amounts due and owing to the Depositor, the Master Servicer, the
Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee hereunder through the date of the liquidation
of the Trust Fund that may be withdrawn from the Collection Account or a Distribution Account, but only to the extent that such
amounts are not already on deposit in the Collection Account. Upon confirmation that such final deposits have been made and following
the surrender of all remaining Certificates (other than the Class S and Class R Certificates) by the Remaining Certificateholder
on the Termination Date, the Custodian shall, upon receipt of a Request for Release from the Master Servicer, release or cause
to be released to the Remaining Certificateholder or any designee thereof, the Mortgage Files for the remaining Mortgage Loans
and shall execute all assignments, endorsements and other instruments furnished to it by the Remaining Certificateholder as shall
be necessary to effectuate transfer of the Mortgage Loans and REO Properties (and including the Trust Fund’s interest in
any REO Property acquired with respect to the Outside Serviced Mortgage Loans) remaining in the Trust Fund, and the Trust Fund
shall be liquidated in accordance with this Section 9.01. Thereafter, the Trust Fund and the respective obligations
and responsibilities under this Agreement of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor,
the Certificate Administrator and the Trustee (other than the making of certain payments to Certificateholders and Serviced Companion
Loan Holders, sending of certain notices, the maintenance of books and records and the preparation and filing of final tax returns),
shall terminate. Such transfers shall be subject to any rights of any Sub-Servicers to service (or to perform select servicing
functions with respect to) the Mortgage Loans. For federal income tax purposes, the Remaining Certificateholder shall be
deemed to have purchased the assets of the Lower-Tier REMIC for an amount equal to the remaining Certificate Balance of its remaining
Certificates (other than the Class S and Class R Certificates), plus accrued and unpaid interest with respect thereto, and
the Certificate Administrator shall credit such amounts against amounts distributed in respect of the Lower-Tier Regular Interests
and such Certificates. The remaining Mortgage Loans and REO Properties (or the Trust’s interests therein) are deemed distributed
to the Remaining Certificateholder in liquidation of the Trust Fund pursuant to this Section 9.01.

Sub-Servicers; Subcontractors.


 


(a)       For
so long as the Trust or any Other Securitization Trust is subject to the reporting requirements of the Exchange Act (in addition
to any requirements contained in Section 10.07 of this Agreement), in connection with the succession to the Master
Servicer, the Special Servicer or any Sub-Servicer as servicer or sub-servicer (to the extent such Sub-Servicer is a “servicer”

Person (i) into which the Master Servicer, the Special Servicer, such Sub-Servicer or Certificate Administrator may be merged
or consolidated, or (ii) which may be appointed as a successor to the Master Servicer, the Special Servicer, any such Sub-Servicer
or Certificate Administrator, the Certificate Administrator (or, in the case of a successor to the Certificate Administrator,
the Trustee) shall provide to the Depositor, as well as any Other Depositor as to which the applicable 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, otherwise no later than one
(1) Business Day after such effective date, (x) written notice to the Depositor and each such Other Depositor of such succession
or appointment and (y) in writing and in form and substance reasonably satisfactory to the Depositor and each such Other

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). The Certificate Administrator (or the Trustee, if applicable) shall provide
similar notice to the Depositor and each such Other Depositor in connection with any resignation or termination of the Master
Servicer, the Special Servicer, any Sub-Servicer or the Certificate Administrator. In addition, with respect to each Serviced

obligations
under each Co-Lender Agreement (including with respect to the provision of any required notices) in connection with any resignation,
termination, replacement or appointment of the Master Servicer, the Special Servicer, any Sub-Servicer or the Certificate Administrator
or any successor thereto.


 


(b)       For
so long as the Trust or any Other Securitization Trust is subject to the reporting requirements of the Exchange Act, if the Master
Servicer, the Special Servicer, any Sub-Servicer, the Custodian, the Trustee and the Certificate Administrator (each of the Master
Servicer, the Special Servicer, the Custodian, the Trustee and the Certificate Administrator and each Sub-Servicer, for purposes
of this Section 10.02(b), Section 10.02(c), Section 10.02(d) and Section 10.17, a “Servicer”)

Participant used by such Servicer for the benefit of the Depositor to comply with the provisions of Section 10.09
and Section 10.10 of this Agreement to the same extent as if such Subcontractor were such Servicer. Such Servicer
shall obtain from each such Subcontractor (or, in the case of each Sub-Servicer set forth on Exhibit S, shall use
commercially reasonable efforts to cause 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 10.09
and Section 10.10 of this Agreement, in each case, as and when required to be delivered.


 


(c)       For
so long as the Trust or any Other Securitization Trust is subject to the reporting requirements of the Exchange Act, notwithstanding
the foregoing, if a Servicer engages a Subcontractor in connection with the performance of any of its duties under this Agreement,
such Servicer shall be responsible for determining whether such Subcontractor is a “servicer” within the meaning of
Item 1101 of Regulation AB and whether such Subcontractor meets the criteria in Item 1108(a)(2)(i), (ii) or (iii) of
Regulation AB. If a Servicer determines, pursuant to the preceding sentence, that such Subcontractor is a “servicer”
within the meaning of Item 1101 of Regulation AB and meets the criteria in Item 1108(a)(2)(i), (ii) or (iii) of Regulation
AB, then the engagement of such Subcontractor shall not be effective unless and until notice is given to the Depositor and the
Certificate Administrator, as well as any Other Depositor as to which the applicable Companion Loan is affected, of any such Subcontractor
and sub-servicing agreement and, if such Subcontractor is engaged by the Master Servicer or the Special Servicer, such Subcontractor
shall be deemed to be a Sub-Servicer for purposes of this Agreement. Written notice of the engagement of such Subcontractor and
the related Sub-Servicing Agreement (other than such agreements set forth on Exhibit S hereto) (with respect to the Master
Servicer or the Special Servicer) or sub-servicing agreement (with respect to any other Servicer) shall be delivered to the Depositor,
the Certificate Administrator and each such Other Depositor at least five (5) Business Days prior to the effective date of such
engagement. Such notice shall contain all information reasonably necessary, and in such form as may be necessary, to enable the
Certificate Administrator, as well as any Other Exchange Act Reporting Party as to which the applicable

Serviced
Companion Loan is affected, to accurately and timely report the event under Item 6.02 of Form 8-K pursuant to Section 10.07
of this Agreement (if such reports under the Exchange Act are required to be filed under the Exchange Act).


 


(d)       For
so long as the Trust or any Other Securitization Trust is subject to the reporting requirements of the Exchange Act, notwithstanding
the foregoing and subject to Section 3.01(c) of this Agreement, if the Master Servicer or the Special Servicer engages
a Sub-Servicer or if any other Servicer engages a sub-servicer, in each case, in connection with the performance of any of the
duties of the Master Servicer, the Special Servicer or such other Servicer, as applicable, under this Agreement and the related
Sub-Servicing Agreement (with respect to the Master Servicer or the Special Servicer) or sub-servicing agreement (with respect
to any other Servicer) is either (i) assigned (other than, in the case of a Sub-Servicer engaged by the Master Servicer, an assignment
to the Master Servicer) or (ii) amended or modified and the Master Servicer, the Special Servicer or such other Servicer, as applicable,
determines that, as a result of such amendment or modification, the Sub-Servicer or sub-servicer, as applicable, would become
a “servicer” within the meaning of Item 1101 of Regulation AB that (1) meets the criteria in Item 1108(a)(2)(i), (ii)
or (iii) of Regulation AB or (2) meets the criteria in Item 1108(a)(2)(iii) of Regulation AB and services 20% or more of the pool
assets, then the Master Servicer, the Special Servicer or such other Servicer, as applicable, shall provide written notice of
such amendment, modification or assignment to the Depositor and the Certificate Administrator, as well as any Other Depositor
as to which the applicable Companion Loan is affected at least five (5) Business Days prior to the effective date of such amendment,
modification or assignment (or if such prior notice would be violative of applicable law or any applicable confidentiality agreement,
no later than the time required under Section 10.07 of this Agreement). Such notice shall contain all information reasonably
necessary, and in such form as may be necessary, to enable the Certificate Administrator, as well as any Other Exchange Act Reporting
Party as to which the applicable Serviced Companion Loan is affected, to accurately and timely report the event under Item 6.02
of Form 8-K pursuant to Section 10.07 of this Agreement (if such reports under the Exchange Act are required to be
filed under the Exchange Act).


 


(e)       For
so long as the Trust or any Other Securitization Trust is subject to the reporting requirements of the Exchange Act, in connection
with the succession to the Trustee or Certificate Administrator under this Agreement by any Person (i) into which the Trustee
or Certificate Administrator may be merged or consolidated, or (ii) which may be appointed as a successor to the Trustee
or Certificate Administrator, the Trustee or Certificate Administrator, as applicable, shall notify the Depositor and each Other
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 10.07
of this Agreement) and shall furnish pursuant to Section 10.07 of this Agreement to the Depositor and each Other
Depositor in writing and in form and substance reasonably satisfactory to the Depositor and each Other Depositor, all information

Obligations.


 


(a)       The
Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian, the Certificate
Administrator and the Trustee shall (and shall cause (or, in the case of a Mortgage Loan Seller Sub-Servicer, shall use commercially
reasonable efforts to cause) each Additional Servicer and Servicing Function Participant utilized thereby to) reasonably cooperate
with the Depositor and each Other Depositor in connection with the satisfaction of the Trust’s and each Other Securitization
Trust’s reporting requirements under the Exchange Act. Pursuant to Section 10.04, Section 10.05
and Section 10.07, the Certificate Administrator shall prepare for execution by the Depositor any Forms 10-D,
ABS-EE, 10-K and 8-K required by the Exchange Act with respect to the Trust, in order to permit the timely filing thereof, and
the Certificate Administrator shall file (via the Commission’s Electronic Data Gathering and Retrieval System) such Forms
executed by the Depositor.


 


(b)       In
the event that the Certificate Administrator is unable to timely file with the Commission or deliver to any Other Depositor or
Other Exchange Act Reporting Party as to which the applicable Companion Loan is affected, all or any required portion of any Form 8-K,
10-D, ABS-EE or 10-K required to be filed by this Agreement because required disclosure information was either not delivered to
it or delivered to it after the delivery deadlines set forth in this Agreement, the Certificate Administrator shall promptly as
soon as practicable, but in no event later than twenty-four (24) hours after determination (but if the next calendar day is not
a Business Day, then in no event later than 10:00 a.m., New York time, on the next Business Day), notify the Depositor, such Other
Depositor or Other Exchange Act Reporting Party thereof. In the case of Forms 10-D, ABS-EE and 10-K, the Depositor and the
Certificate Administrator will thereupon cooperate to prepare and file a Form 12b-25 and a Form 10-D/A, Form ABS-EE/A
or Form 10-K/A, as applicable, pursuant to Rule 12b-25 of the Exchange Act. In the case of Form 8-K, the Certificate
Administrator will, upon receipt of all required Form 8-K Disclosure Information, include such disclosure information on
the next succeeding Form 10-D to be filed for the Trust. In the event that any previously filed Form 8-K or Form 10-K
needs to be amended, the Certificate Administrator will notify the Depositor thereof, and such other parties as needed and the
parties hereto will cooperate with the Certificate Administrator to prepare any necessary Form 8-K/A or Form 10-K/A.
In the event that any previously filed Form 10-D or Form ABS-EE needs to be amended, the Certificate Administrator shall
notify the Depositor thereof, and such other parties as needed, and the parties hereto shall cooperate to prepare any necessary
Form 10-D/A or Form ABS-EE/A. Any Form 12b-25 or any amendment to Form 8-K, Form 10-D, Form ABS-EE/A or Form 10-K
shall be signed by an officer of the Depositor. The parties to this Agreement acknowledge that the performance by the Certificate
Administrator of its duties under this Section 10.03 related to the timely preparation and filing of Form 12b-25 or
any amendment to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K is contingent upon such parties observing all applicable
deadlines in the performance of their duties under this Article X. The Certificate Administrator shall have no liability
for any loss, expense, damage, or claim arising out of or with respect to any failure to properly prepare, arrange for execution
and/or timely file any such Form 12b-25 or any amendments to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K,
where such failure results from the Certificate Administrator’s inability or failure to receive, on a timely basis, any
information from any other party hereto needed to prepare, arrange for execution or file such Form 12b-25 or any amendments
to Forms 8-K, Form 10-D, Form ABS-EE or Form 10-K, not resulting from its own negligence, bad faith or willful
misconduct.

Form 10-D Disclosure that is true and accurate in all material respects and in compliance with all applicable requirements of
the Securities Act and the Exchange Act, and the rules and regulations promulgated thereunder. The Certificate Administrator has
no duty under this Agreement to monitor or enforce the performance by the parties listed on Exhibit U to this Agreement
of their duties under this paragraph or proactively solicit or procure from such parties any Additional Form 10-D Disclosure

prepare, arrange for execution and/or timely file any Form 10-D or Form ABS-EE with respect to the Trust, where such failure
results because required disclosure information was either not delivered to the Certificate Administrator or delivered to the

a Sub-Servicing Agreement (with respect to the Master Servicer or the Special Servicer) or sub-servicing agreement (with respect
to any other Servicer) as aforesaid shall not limit any right Master Servicer, the Special Servicer, the Custodian, the Certificate

Article
XI



ASSET REVIEW PROVISIONS


 


Section 11.01       
Asset Review.


 


(a)            
On or prior to each Distribution Date, based on the CREFC® Delinquent Loan Status Report and/or the CREFC®
Loan Periodic Update File delivered by the Master Servicer for such Distribution Date, the Certificate Administrator shall
determine if an Asset Review Trigger has occurred during the related Collection Period. If an Asset Review Trigger is determined
to have occurred, the Certificate Administrator shall promptly provide notice to the Asset Representations Reviewer, the Master
Servicer, the Special Servicer and all Certificateholders. Any notice required to be delivered to the Certificateholders pursuant
to this Article XI shall be delivered by the Certificate Administrator (i) by posting such notice on the Certificate Administrator’s
Website and (ii) by mailing such notice to the Certificateholders’ addresses appearing in the Certificate Register in the
case of Definitive Certificates and by delivering such notice via the Depository in the case of Book-Entry Certificates. The Certificate
Administrator shall include in the Form 10-D relating to the Collection Period in which the Asset Review Trigger occurred, notice
of its determination together with the following statement describing the events that caused the Asset Review Trigger to occur:
“As of the [Date of Distribution], the following Mortgage Loans identified below are 60 or more days delinquent and an Asset
Review Trigger as defined in the Pooling and Servicing Agreement has occurred.” On each Distribution Date occurring after
providing such notice to Certificateholders, the Certificate Administrator, based on information provided to it by the Master
Servicer and/or the Special Servicer, as applicable, shall determine whether (1) any additional Mortgage Loan has become
a Delinquent Loan, (2) any Mortgage Loan has ceased to be a Delinquent Loan and (3) whether an Asset Review Trigger
has ceased to exist, and, if there is an occurrence of any of the events or circumstances identified in clauses (1), (2)
and/or (3), deliver such information in a written notice (which may be via email) in the form of Exhibit LL
within two (2) Business Days of such determination to the Master Servicer, the Special Servicer, the Operating Advisor and the
Asset Representations Reviewer.


 


If
Certificateholders evidencing not less than 5% of the aggregate Voting Rights of the Certificates deliver to the Certificate Administrator,
within 90 days after the filing of the Form 10-D reporting the occurrence of an Asset Review Trigger, a written direction requesting
a vote to commence an Asset Review (an “Asset Review Vote Election”), then the Certificate Administrator shall
promptly provide written notice thereof to the Asset Representations Reviewer and to all Certificateholders and conduct a solicitation
of votes in accordance with Section 5.12 regarding whether to authorize an Asset Review. In the event there is an affirmative
vote to authorize an Asset Review by Holders of Certificates evidencing at least a majority of an Asset Review Quorum within 150 days
of receipt of the Asset Review Vote Election (an “Affirmative Asset Review


 






    	-441- 



     


    

 


Vote”),
the Certificate Administrator shall promptly provide written notice thereof (the “Asset Review Notice”) to
all parties to this Agreement, the Underwriters, the Mortgage Loan Sellers, the Directing Holder and the other Certificateholders
(such notice to Certificateholders to be effected by posting such notice on the Certificate Administrator’s Website and
by mailing such notice to the Certificateholders’ addresses appearing in the Certificate Register in the case of Definitive
Certificates and by delivering such notice via the Depository in the case of Book-Entry Certificates). Upon receipt of an Asset
Review Notice, the Asset Representations Reviewer shall request access to the Secure Data Room by providing the Certificate Administrator
with a certification substantially in the form attached hereto as Exhibit KK. Upon receipt of such certification, the Certificate
Administrator shall grant the Asset Representations Reviewer access to the Secure Data Room. In the event an Affirmative Asset
Review Vote has not occurred within such 150-day period following the receipt of the Asset Review Vote Election, no Certificateholder
may request a vote or cast a vote for an Asset Review and the Asset Representations Reviewer will not be required to review any
Delinquent Loan unless and until (A) an additional Mortgage Loan has become a Delinquent Loan after the expiration of such
150-day period, (B) a new Asset Review Trigger has occurred as a result or an Asset Review Trigger is otherwise in effect,
(C) the Certificate Administrator has received an Asset Review Vote Election within 90 days after the filing of a Form 10-D
reporting the occurrence of the events described in clauses (A) and (B) in this sentence and (D) an Affirmative Asset Review
Vote has occurred within 150 days after the Asset Review Vote Election described in clause (C) in this sentence. After the
occurrence of any Asset Review Vote Election or an Affirmative Asset Review Vote, no Certificateholder may make any additional
Asset Review Vote Election except as described in the immediately preceding sentence. Any reasonable out-of-pocket expenses incurred
by the Certificate Administrator in connection with administering such vote will be paid as an expense of the Trust from the Collection
Account. The Certificate Administrator shall be entitled to administer any vote in connection with the foregoing through an agent.


 


(b)           
(i) Upon receipt from the Certificate Administrator of an Asset Review Notice with respect to a Delinquent Mortgage Loan, the
Custodian (with respect to clauses (1) – (5) below for all of the Mortgage Loans), the Master Servicer
(with respect to clause (6) below for Non-Specially Serviced Loans) and the Special Servicer (with respect to clause (6)
below for Specially Serviced Loans) shall promptly (but (except with respect to clause (6)) in no event later than ten (10)
Business Days after receipt of such notice from the Certificate Administrator) provide, in electronic format, the following materials
for such Delinquent Loan, in each case to the extent in such party’s possession, to the Asset Representations Reviewer (collectively,
with the Diligence Files posted on the Secure Data Room by the Certificate Administrator pursuant to Section 4.09, a copy
of the Prospectus, a copy of each related Mortgage Loan Purchase Agreement and a copy of this Agreement, the “Review
Materials”):


 


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


 


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


 






    	-442- 



     


    

 


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


 


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


 


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


 


(6)              any
other related documents that are required to be part of the Review Materials and requested to be delivered by the Master Servicer
(with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) to the Asset
Representations Reviewer pursuant to clause (vii) below of this Section 11.01(b).


 


(ii)           
Notwithstanding the foregoing, the Mortgage Loan Seller will not be required to deliver any information that is proprietary to
the Mortgage Loan Seller or any draft documents, privileged or internal communications, credit underwriting or due diligence analysis.


 


(iii)          
The Asset Representations Reviewer may, but is under no obligation to, consider and rely upon information furnished to it by a
Person that is not a party to this Agreement or the applicable Mortgage Loan Seller, and shall do so only if such information
can be independently verified (without unreasonable effort or expense to the Asset Representations Reviewer) and is determined
by the Asset Representations Reviewer in its good faith and sole discretion to be relevant to the Asset Review conducted pursuant
to this Section 11.01 (any such information, “Unsolicited Information”).


 


(iv)         
Upon receipt by the Asset Representations Reviewer of the Asset Review Notice and access to the Diligence Files posted to the
Secure Data Room with respect to a Delinquent Loan, the Asset Representations Reviewer, as an independent contractor, shall commence
a review of the compliance of each Delinquent Loan with the representations and warranties related to that Delinquent Loan (such
review, the “Asset Review”). The Asset Representations Reviewer shall perform an Asset Review with respect
to each representation and warranty made by the related Mortgage Loan Seller with respect to such Delinquent Loan in accordance
with the Asset Review Standard and the procedures set forth on Exhibit JJ (each such procedure, a “Test”).
Once an Asset Review of a Mortgage Loan is completed, no further Asset Review shall be required in respect of, or performed on,
such Mortgage Loan notwithstanding that such Mortgage Loan may continue to be a Delinquent Loan or again become a Delinquent Loan
at a time when a new Asset Review Trigger occurs and a new Affirmative Asset Review Vote is obtained subsequent to the occurrence
of such new Asset Review Trigger.


 


(v)           
No Certificateholder shall have the right to change the scope of the Asset Review, and the Asset Representations Reviewer shall
not be required to review any


 






    	-443- 



     


    

 


information
other than (1) the Review Materials and (2) if applicable, Unsolicited Information.


  


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


 


(vii)         
In connection with an Asset Review, the Asset Representations Reviewer shall comply with the following procedures with respect
to each Delinquent Loan:


 


(A)           
Within 10 Business Days after the date on which the Review Materials identified in clauses (i) through (v) of the definition of
“Review Materials” have been received by the Asset Representations Reviewer with respect to such Delinquent Loan or
in any event within 15 days after the date on which access to the Secure Data Room is provided to the Asset Representations Reviewer
by the Certificate Administrator, in the event that the Asset Representations Reviewer reasonably determines that any Review Materials
made available or delivered to the Asset Representations Reviewer are missing any documents required to complete any Test for
such Delinquent Loan, the Asset Representations Reviewer shall promptly notify the Master Servicer (with respect to Non-Specially
Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans), as applicable, of such missing documents,
and request that the Master Servicer or the Special Servicer, as applicable, promptly (but in no event later than 10 Business
Days after receipt of notification from the Asset Representations Reviewer) deliver to the Asset Representations Reviewer such
missing documents in its possession; provided that any such notification and/or request shall be in writing, specifically identifying
the documents being requested and sent to the notice address for the related party set forth in Section 12.04 of this Agreement.
In the event any missing documents are not provided by the Master Servicer or the Special Servicer, as applicable, within such
10-Business Day period, the Asset Representations Reviewer shall request such documents from the related Mortgage Loan Seller;
provided that the Mortgage Loan Seller will be required under the related Mortgage Loan Purchase Agreement to deliver any
such missing documents only to the extent such document is in the possession of the Mortgage Loan Seller.


 


(B)           
Following the events in clause (A) above, and within 45 days after the date on which access to the Secure Data Room is provided
to the Asset Representations Reviewer by the Certificate Administrator, the Asset Representations Reviewer shall prepare a preliminary
report with respect to such Delinquent Loan setting forth (i) the preliminary results of the application of the Tests, (ii) if
applicable, whether the Review Materials for such Delinquent Loan are insufficient to complete any Test, (iii) a list of any applicable
missing documents together with the reasons why such missing documents are necessary to complete any Test, and (iv) (if the Asset
Representations Reviewer has so concluded) whether the absence of such documents will be deemed to be a failure of such Test (collectively,
the “Preliminary Asset Review Report”). The Asset


 






    	-444- 



     


    

 


Representations
Reviewer shall provide each Preliminary Asset Review Report to the Master Servicer (with respect to Non-Specially Serviced Loans)
or the Special Servicer (with respect to Specially Serviced Loans), who shall promptly, but in no event later than 10 Business
Days of receipt thereof, provide the Preliminary Asset Review Report to the applicable Mortgage Loan Seller. The Asset Representations
Reviewer shall include the following statement in the related correspondence when providing each Preliminary Asset Review Report
to the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced
Loans): “This is a Preliminary Asset Review Report regarding an Asset Review under Section 11.01 of the Pooling and Servicing
Agreement relating to the Citigroup Commercial Mortgage Trust 2017-C4, Commercial Mortgage Pass-Through Certificates, Series 2017-C4,
requiring action by you as the recipient of such Preliminary Asset Review Report. You are required to deliver the Preliminary
Asset Review Report to the applicable Mortgage Loan Seller no later than 10 Business Days after receipt of the Preliminary Asset
Review Report”. If the Preliminary Asset Review Report indicates that any of the representations and warranties fails or
is deemed to fail any Test, the applicable Mortgage Loan Seller shall have 90 days from its receipt of the Preliminary Asset Review
Report (the “Cure/Contest Period”) to remedy or otherwise refute the failure. The applicable Mortgage Loan
Seller will be required under the related Mortgage Loan Purchase Agreement to provide any documents or any explanations to support
(i) a conclusion that a subject representation and warranty has not failed a Test or (ii) a claim that any missing documents in
the Review Materials are not required to complete a Test, in any such case to the Master Servicer (with respect to Non-Specially
Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans), and the Master Servicer or the Special Servicer,
as applicable, shall promptly, but in no event later than ten (10) Business Days after receipt from the applicable Mortgage Loan
Seller, deliver to the Asset Representations Reviewer any such documents or explanations received from the applicable Mortgage
Loan Seller given to support a claim that the representation and warranty has not failed a Test or a claim that any missing documents
in the Review Materials are not required to complete a Test.


 


(C)           
Within the later of (x) 60 days after the date on which access to the Secure Data Room is provided to the Asset Representations
Reviewer by the Certificate Administrator, and (y) 10 Business Days after the expiration of the Cure/Contest Period, the Asset
Representations Reviewer shall complete an Asset Review with respect to each Delinquent Loan and deliver (i) a report, substantially
in the form attached hereto as Exhibit HH, setting forth the Asset Representations Reviewer’s findings and conclusions
as to whether or not it has determined there is any evidence of a failure of any Test based on the Asset Review, together with
a statement that the Asset Representations Reviewer’s findings and conclusions set forth in such report were not influenced
by any third party (an “Asset Review Report”), to each party to this Agreement, the related Mortgage Loan Seller
and the Controlling Class Representative (if such Delinquent Loan is not an Excluded Mortgage Loan), and (ii) a summary of the
Asset Representations Reviewer’s conclusions included in such Asset Review Report (an “Asset Review Report


 






    	-445- 



     


    

 


Summary”)
, substantially in the form attached hereto as Exhibit II, to the Trustee and Certificate Administrator (who shall include such
Asset Review Report Summary in the Form 10-D relating to the Collection Period in which such Asset Review Report Summary is received
and post such Asset Review Report Summary on the Certificate Administrator’s Website in accordance with Section 10.04(e)).
The period of time by which the Asset Review Report must be completed and delivered may be extended by up to an additional 30 days,
upon written notice to the parties to this Agreement and the applicable Mortgage Loan Seller(s), if the Asset Representations
Reviewer determines pursuant to the Asset Review Standard that such additional time is required due to the characteristics of
the Delinquent Loan(s) and/or the Mortgaged Property or Mortgaged Properties. In addition, in the event that the Asset Representations
Reviewer does not receive any documentation that it requested from the Master Servicer (with respect to Performing Serviced Loans),
the Special Servicer (with respect to Specially Serviced Loans) or the applicable Mortgage Loan Seller in sufficient time to allow
the Asset Representations Reviewer to complete its Asset Review and deliver an Asset Review Report, the Asset Representations
Reviewer shall prepare the Asset Review Report solely based on the documents received by the Asset Representations Reviewer with
respect to the related Delinquent Loan, and the Asset Representations Reviewer shall have no responsibility to independently obtain
any such documents from any party to this or otherwise.


 


(viii)         
Within thirty (30) days after receipt of an Asset Review Report with respect to any Mortgage Loan, the Enforcing Servicer shall
determine, based on the Servicing Standard, whether there exists a Material Defect with respect to such Mortgage Loan. If the
Enforcing Servicer determines that a Material Defect exists, the Enforcing Servicer shall enforce the obligations of the related
Mortgage Loan Seller (and, if necessary in the case of LCF, the obligations of Ladder Capital Finance Holdings LLLP, Series REIT
of Ladder Capital Finance Holdings LLLP and Series TRS of Ladder Capital Finance Holdings LLLP in respect of their respective
payment guaranties) with respect to such Material Defect in accordance with Section 2.03(a).


 


(ix)            
In no event may the Asset Representations Reviewer determine whether any Test failure constitutes a Material Defect, or whether
the Trust should enforce any rights it may have against the applicable Mortgage Loan Seller (or, in the case of LCF, against Ladder
Capital Finance Holdings LLLP, Series REIT of Ladder Capital Finance Holdings LLLP and Series TRS of Ladder Capital Finance Holdings
LLLP in respect of their respective payment guaranties), which, in each case, shall be the responsibility of the Enforcing Servicer
pursuant to Section 2.03(a) or Section 11.01(b)(viii) of this Agreement.


 


(c)            
The Asset Representations Reviewer and its Affiliates shall keep confidential any Privileged Information received from any party
to this Agreement or any Sponsor (including, without limitation, in connection with the review of the Mortgage Loans) and not
disclose such Privileged Information to any Person (including Certificateholders), other than (1) to the extent expressly
required by this Agreement in an Asset Review Report or otherwise, to the other parties to this Agreement with a notice indicating
that such information is Privileged Information or (2) pursuant to a Privileged Information Exception. Each party to this
Agreement


 






    	-446- 



     


    

 


that
receives Privileged Information from the Asset Representations Reviewer with a notice stating that such information is Privileged
Information shall not disclose such Privileged Information to any Person without the prior written consent of the Special Servicer
other than pursuant to a Privileged Information Exception. In addition, the Asset Representations Reviewer shall keep all documents
and information received by the Asset Representations Reviewer in connection with an Asset Review that are provided by the applicable
Mortgage Loan Seller, the Master Servicer and the Special Servicer confidential and shall not disclose such documents except for
purposes of complying with its duties and obligations hereunder.


 


(d)           
The Asset Representations Reviewer may delegate its duties to agents or subcontractors so long as the related agreements or arrangements
with such agents or subcontractors are consistent with the provisions of this Section 11.01; provided that no agent
or subcontractor may (i) be affiliated with any Mortgage Loan Seller, Master Servicer, Special Servicer, the Depositor, the
Certificate Administrator, the Trustee, the Controlling Class Representative or any of their respective Affiliates or (ii) have
been paid any fees, compensation or other remuneration by an Underwriter, Master Servicer, Special Servicer, the Depositor, the
Certificate Administrator, the Trustee, the Controlling Class Representative or any of their respective Affiliates in connection
with due diligence or other services with respect to any Mortgage Loan prior to the Closing Date. Notwithstanding the foregoing
sentence, the Asset Representations Reviewer shall remain obligated and primarily liable for any Asset Review required hereunder
in accordance with the provisions of this Agreement without diminution of such obligation or liability or related obligation or
liability by virtue of such delegation or arrangements or by virtue of indemnification from any Person acting as its agents or
subcontractor to the same extent and under the same terms and conditions as if the Asset Representations Reviewer alone were performing
its obligations under this Agreement. The Asset Representations Reviewer shall be entitled to enter into an agreement with any
agent or subcontractor providing for indemnification of the Asset Representations Reviewer by such agent or subcontractor, and
nothing contained in this Agreement shall be deemed to limit or modify such indemnification.


 


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

Section 11.02  
Payment of Asset Representations Asset Review Fee and Expenses; Limitation of Liability.


 


(a)            
As compensation for the performance of its routine duties, the Asset Representations Reviewer shall be paid as an ongoing fee
(the “Asset Representations Reviewer Ongoing Fee”), payable monthly from amounts received in respect of each
Mortgage Loan (including any Outside Serviced Mortgage Loan), and for any Distribution Date an amount accrued during the related
Interest Accrual Period at 0.00026% per annum (the “Asset Representations Reviewer Ongoing Fee Rate”)
on, in the case of the initial Distribution Date, the Cut-Off Date Balance of such Mortgage Loan and, in the case of any subsequent
Distribution Date, the Stated Principal Balance of such Mortgage Loan as of the close of business on the Distribution Date in
such Interest Accrual Period, and shall be calculated on the same interest accrual basis as the related Mortgage Loan and prorated
for any partial periods. The Asset Representations Reviewer Ongoing Fee shall be payable from amounts on deposit in the Collection
Account as set forth in Section 3.06(a).


 


(b)         
   Upon the completion of an Asset Review with respect to each Delinquent Loan and receipt by the related Mortgage
Loan Seller of a written invoice from the Asset Representations Reviewer, the related Mortgage Loan Seller is required under
the related Mortgage Loan Purchase Agreement to pay to the Asset Representations Reviewer within forty-five (45) days after
such written invoice a fee (the “Asset Representations Reviewer Asset Review Fee”) that is equal to the
sum of: (i) $15,000 multiplied by the number of Delinquent Loans subject to any Asset Review (for purposes of this Section
11.02(b), the “Subject Loans”), plus (ii) $1,500 per Mortgaged Property relating to the Subject Loans in
excess of one Mortgaged Property per Subject Loan, plus (iii) $2,000 per Mortgaged Property relating to a Subject Loan
subject to a Ground Lease, plus (iv) $1,500 per Mortgaged Property relating to a Subject Loan subject to a franchise
agreement, hotel management agreement or hotel license agreement, subject, in the case of each of clauses (i) through (iv),
to annual adjustments on the basis of the year-end Consumer Price Index for All Urban Consumers or, if the Consumer Price
Index for All Urban Consumers is no longer calculated, another similar index for the year of the Closing Date and for the
year in which the related Asset Review Notice is given. The Asset Representations Reviewer Asset Review Fee with respect to
each Delinquent Loan shall be paid by the related Mortgage Loan Seller; provided, however, that if (i) the
related Mortgage Loan Seller is insolvent or (ii) at any time after the outstanding Certificate Balances of the Control
Eligible Certificates have been reduced to zero as a result of the allocation of Realized Losses to such Certificates, the
related Mortgage Loan Seller fails to pay such amount within 90 days following receipt of the Asset Representations
Reviewer’s invoice, then such fee shall be paid by the Trust Fund following delivery by the Asset Representations
Reviewer of evidence reasonably satisfactory to the Special Servicer of such insolvency or failure to pay such amount; and provided, further,
that notwithstanding any payment of such fee by the Trust to the Asset Representations Reviewer, such fee will remain an
obligation of the related Mortgage Loan Seller, and the Special Servicer shall determine whether to pursue (and, if it
determines to do so, shall pursue) remedies against such Mortgage Loan Seller or its insolvency estate to recover any such
amounts to the extent paid by the Trust. If paid by the Trust Fund as described in the immediately preceding sentence, the
Asset Representations Reviewer Asset Review Fee with respect to each Delinquent Loan shall be payable from funds on deposit
in the Collection Account as set forth in Section 3.06(a).


 






    	-448- 



     


    

 


(c)            
Notwithstanding the foregoing, the Asset Representations Reviewer Asset Review Fee with respect to a Delinquent Loan shall be
included in the Purchase Price for any such Delinquent Loan that was the subject of a completed Asset Review that is repurchased
by a Mortgage Loan Seller, and such portion of the Purchase Price received shall be used to reimburse the Asset Representations
Reviewer or the Trust, as the case may be, for such fees pursuant to Section 11.02(b).


 


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


 


Section 11.03   Resignation
of the Asset Representations Reviewer.  The Asset Representations Reviewer may resign and
be discharged from its obligations hereunder by giving written notice thereof to the other parties to this Agreement and each
Rating Agency. In addition, the Asset Representations Reviewer shall at all times be an Eligible Asset Representations
Reviewer, and shall resign if it fails to be an Eligible Asset Representations Reviewer (and such failure results in an Asset
Representations Reviewer Termination Event) by giving written notice to the Depositor, the Master Servicer, the Special
Servicer, the Trustee, the Operating Advisor, the Certificate Administrator and the Directing Holder. Upon such notice of
resignation, the Depositor shall promptly appoint a successor asset representations reviewer that is an Eligible Asset
Representations Reviewer. No resignation of the Asset Representations Reviewer will be effective until a successor
Asset Representations Reviewer that is an Eligible Asset Representations Reviewer has been appointed and accepted the
appointment. If no successor Asset Representations Reviewer shall have been so appointed and have accepted appointment within
30 days after the giving of such notice of resignation, the resigning Asset Representations Reviewer may petition any
court of competent jurisdiction for the appointment of a successor asset representations reviewer that is an Eligible Asset
Representations Reviewer. The Asset Representations Reviewer shall bear all costs and expenses of each party hereto and each
Rating Agency in connection with its resignation and the transfer of its duties.


 


Section 11.04  
Restrictions of the Asset Representations Reviewer. Neither the Asset Representations Reviewer nor any of its Affiliates
shall make any investment in any Class of Certificates; provided, however, that such prohibition shall not apply
to (i) riskless principal transactions effected by a broker dealer Affiliate of the Asset Representations Reviewer or (ii) investments
by an Affiliate of the Asset Representations Reviewer if the Asset Representations Reviewer and such Affiliate maintain policies
and procedures that (A) segregate personnel involved in the activities of the Asset Representations Reviewer under this Agreement
from personnel involved in such Affiliate’s investment activities and (B) prevent such Affiliate and its personnel
from gaining access to information regarding the Trust and the Asset Representations Reviewer and its personnel from gaining access
to such Affiliate’s information regarding its investment activities.


 


Section 11.05  
Termination of the Asset Representations Reviewer.


 


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


 






    	-449- 



     


    

 


(i)             
any failure by the Asset Representations Reviewer to observe or perform in any material respect any of its covenants or agreements
or the material breach of any of its representations or warranties under this Agreement, which failure shall continue unremedied
for a period of thirty (30) days after the date on which written notice of such failure is given to the Asset Representations
Reviewer by the Trustee or to the Asset Representations Reviewer and the Trustee by the Holders of Certificates having greater
than 25% of the aggregate Voting Rights; provided, however, that with respect to any such failure which is not curable
within such 30-day period, the Asset Representations Reviewer will have an additional cure period of 30 days to effect such cure
so long as it has commenced to cure such failure within the initial 30-day period and has provided the Trustee and the Certificate
Administrator with an Officer’s Certificate certifying that it has diligently pursued, and is continuing to pursue, such
cure;


 


(ii)            
any failure by the Asset Representations Reviewer to perform its obligations hereunder in accordance with the Asset Review Standard
in any material respect, which failure shall continue unremedied for a period of thirty (30) days after the date written notice
of such failure is given to the Asset Representations Reviewer by any party to this Agreement;


 


(iii)     
      any failure by the Asset Representations Reviewer to be an Eligible Asset Representations Reviewer,
which failure shall continue unremedied for a period of thirty (30) days;


 


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


 


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


 


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


 


Upon
receipt by the Certificate Administrator of written notice of the occurrence of any Asset Representations Reviewer Termination
Event, the Certificate Administrator shall promptly provide written notice to all Certificateholders (and simultaneously deliver
such written notice to the Asset Representations Reviewer) in accordance with the notice distribution procedures described in
Section 11.01(a), unless the Certificate Administrator has received written notice that such Asset Representations
Reviewer Termination Event has been remedied. If an


 






    	-450- 



     


    

 


Asset
Representations Reviewer Termination Event shall occur then, and in each and every such case, so long as such Asset Representations
Reviewer Termination Event shall not have been remedied, either the Trustee (i) may or (ii) upon the written direction
of holders of Certificates evidencing not less than 25% of the Voting Rights (without regard to the application of any Appraisal
Reduction Amounts), shall, terminate all of the rights and obligations of the Asset Representations Reviewer under this Agreement,
other than rights and obligations accrued prior to such termination (including the right to receive all amounts accrued and owing
to it under this Agreement) and other than indemnification rights (arising out of events occurring prior to such termination),
by notice in writing to the Asset Representations Reviewer. The Asset Representations Reviewer is required to bear all reasonable
costs and expenses of itself and of each other party to this Agreement in connection with its termination due to an Asset Representations
Reviewer Termination Event. Notwithstanding anything herein to the contrary, the Depositor and each Mortgage Loan Seller shall
have the right, but not the obligation, to notify the Certificate Administrator and the Trustee of any Asset Representations Reviewer
Termination Event of which it becomes aware.


 


(b)           
Upon (i) the written direction of holders of Certificates evidencing not less than 25% of the Voting Rights (without regard
to the application of any Appraisal Reduction Amounts) requesting a vote to terminate and replace the Asset Representations Reviewer
with a proposed successor asset representations reviewer that is an Eligible Asset Representations Reviewer and (ii) payment
by such Holders to the Certificate Administrator of the reasonable fees and expenses to be incurred by the Certificate Administrator
in connection with administering such vote, the Certificate Administrator shall promptly provide written notice of such requested
vote to the Asset Representations Reviewer and to all Certificateholders by (i) posting such notice on the Certificate Administrator’s
Website, and (ii) mailing such notice to all Certificateholders at their addresses appearing in the Certificate Register
and to the Asset Representations Reviewer. Upon the affirmative vote of the Holders of Certificates evidencing at least 75% of
the Voting Rights allocable to the Certificates of those Holders that exercise their right to vote (provided that Holders representing
the applicable Certificateholder Quorum exercise their right to vote within 180 days of the initial request for a vote (which,
for the avoidance of doubt, is the date on which the aforementioned notice was mailed to the Certificateholders)), the Trustee
shall terminate all of the rights and obligations of the Asset Representations Reviewer under this Agreement (other than any rights
or obligations that accrued prior to the date of such termination and other than indemnification rights arising out of events
occurring prior to such termination) by notice in writing to the Asset Representations Reviewer and appoint the proposed successor.
As between the Asset Representations Reviewer, on the one hand, and the Certificateholders, on the other, the Certificateholders
shall be entitled in their sole discretion to vote for the termination or not vote for the termination of the Asset Representations
Reviewer. In the event that Holders of the Certificates entitled to at least 75% of a Certificateholder Quorum elect to remove
the Asset Representations Reviewer without cause and appoint a successor, the successor asset representations reviewer shall be
responsible for all expenses necessary to effect the transfer of responsibilities from its predecessor.


 


(c)            
On or after the receipt by the Asset Representations Reviewer of written notice of termination, subject to this Section 11.05,
all of its authority and power under this Agreement shall be terminated and, without limitation, the terminated Asset Representations
Reviewer shall execute any and all documents and other instruments, and do or accomplish all


 






    	-451- 



     


    

 


other
acts or things reasonably necessary or appropriate to effect the purposes of such notice of termination. As soon as practicable,
but in no event later than 30 days after (1) the Asset Representations Reviewer resigns pursuant to Section 11.03
of this Agreement or (2) the Trustee delivers such written notice of termination to the Asset Representations Reviewer,
the Depositor (in the case of a resignation of the Asset Representations Reviewer pursuant to Section 11.03) or the Trustee
(in the case of a termination of the Asset Representations Reviewer pursuant to Section 11.05(b)), as applicable, shall appoint
a successor asset representations reviewer that is an Eligible Asset Representations Reviewer. The Trustee shall provide written
notice of the appointment of an Asset Representations Reviewer to the Master Servicer, the Special Servicer, the Operating Advisor,
the Certificate Administrator, the Directing Holder and each Certificateholder within one Business Day of such appointment. Notwithstanding
the foregoing, if the Trustee is unable to find a successor asset representations reviewer within thirty (30) days of the termination
of the Asset Representations Reviewer, the Depositor shall be permitted, but not obligated, to find a replacement. The Trustee
shall not be liable for any failure to identify and appoint a successor asset representations reviewer so long as the Trustee
uses commercially reasonable efforts to conduct a search for a successor asset representations reviewer and such failure is not
a result of the Trustee’s negligence, bad faith or willful misconduct in the performance of its obligations hereunder.


 


The
Asset Representations Reviewer shall at all times be an Eligible Asset Representations Reviewer. If the Asset Representations
Reviewer ceases to be an Eligible Asset Representations Reviewer, the Asset Representations Reviewer shall immediately notify
the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Operating Advisor, the Certificate Administrator and
the Directing Holder of such disqualification and, if an Asset Representations Reviewer Termination Event occurs as a result,
immediately resign under Section 11.03 of this Agreement, and a successor asset representations reviewer shall be
appointed in accordance with Section 11.03.


 


(d)            
Upon any termination of the Asset Representations Reviewer and appointment of a successor to the Asset Representations Reviewer,
the Trustee shall, as soon as possible, give written notice thereof to the Special Servicer, the Master Servicer, the Certificate
Administrator (who shall, as soon as possible, give written notice thereof to the Certificateholders), the Operating Advisor,
the Mortgage Loan Sellers, the Depositor, each Rating Agency and, prior to the occurrence and continuance of a Consultation Termination
Event, the Controlling Class Representative. In the event that the Asset Representations Reviewer is terminated, all of its rights
and obligations under this Agreement shall terminate, other than any rights or obligations that accrued prior to the date of such
termination (including the right to receive all amounts accrued and owing to it under this Agreement) and other than indemnification
rights (arising out of events occurring prior to such termination).

other such Holder, or to enforce any right under this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all Holders of Certificates of such Class. 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.

  to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;


 


(ii)        
    to correct or supplement any of its provisions which may be inconsistent with any other provisions of this
Agreement or with the description thereof in the Prospectus or to correct any error;


 


(iii)      
     to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided
that (A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related
Distribution Date and (B) the change would not adversely affect in any material respect the interests of any
Certificateholder, as evidenced by an opinion of counsel (at the expense of the party requesting the amendment);


 


(iv)          
to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the qualification of either
Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition of any tax on the
Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at the expense
of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such qualification
or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests of any
holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of
the Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with
respect to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply
with the Investment Company Act, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions
and/or interpretations or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to

adversely affect such party or materially increase such party’s obligations under this Agreement); provided, further
that notice of such modification is provided to all parties to this Agreement; and


 


(vii)         
to amend or supplement any provision of this Agreement to the extent necessary to maintain the ratings assigned to each Class

the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
this Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner the obligations

not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment 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 Certificateholders; provided, however, that no such amendment shall:


 


(i)            
reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans which are required to be distributed
on a Certificate of any


 






    	-463- 



     


    

 


Class

(viii)

In
the event that neither the Depositor nor any successor thereto, if any, is in existence, any amendment under this Section 12.07
shall be effective with the consent of the Trustee, the Operating Advisor, the Asset Representations Reviewer, the Certificate
Administrator, the Custodian (if the Certificate Administrator is then acting as Custodian), the Special Servicer, the Master
Servicer, in writing, and to the extent required by this Section, the Certificateholders, the Serviced Companion Loan Holders,

the Serviced Companion Loan Holders, the Mortgage Loan Sellers, Underwriters or the Initial Purchasers, as applicable, under this
Section 12.07 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent
shall approve the substance thereof. The


 






    	-464- 



     


    

 


method
of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders or the Serviced
Companion Loan Holders, the Mortgage Loan Sellers, Underwriters or the Initial Purchasers, as applicable, shall be subject to
such reasonable regulations as the Trustee may prescribe; provided, however, that such method shall always be by
affirmation and in writing.


 


Notwithstanding
any contrary provision of this Agreement, no amendment shall be made to this Agreement or any Custodial Agreement unless, if requested
by the Master Servicer, the Special Servicer, the Trustee, the Custodian (if the Certificate Administrator is then acting as Custodian),
and/or the Certificate Administrator, such party shall have received an Opinion of Counsel, at the expense of the party requesting
such amendment (or, if such amendment is required by any Rating Agency to maintain the rating issued by it or requested by the
Trustee or the Certificate Administrator for any purpose described in clause (i) or (ii) of the first sentence of this
Section, then at the expense of the Trust Fund), to the effect that such amendment will not cause either Trust REMIC to fail to
qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust for federal income tax purposes at any time
that any Certificates are outstanding, and will not cause a tax to be imposed on the Trust Fund (other than a tax at the highest
marginal corporate tax rate on net income from foreclosure property pursuant to Code Section 860G(c)). Prior to the execution
of any amendment to this Agreement or any Custodial Agreement, the Trustee, the Certificate Administrator, the Custodian (if the
Certificate Administrator is then acting as Custodian), the Special Servicer and the Master Servicer may request and shall be
entitled to rely conclusively upon an Opinion of Counsel, at the expense of the party requesting such amendment (or, if such amendment
is required by any Rating Agency to maintain the rating issued by it or requested by the Trustee or the Certificate Administrator
for any purpose described in clause (i), (ii), (iii) or (v) (which does not modify or otherwise relate solely to
the obligations, duties or rights of the Trustee or the Certificate Administrator, as applicable) of the first sentence of this
Section, then at the expense of the Trust Fund) stating that the execution of such amendment is authorized or permitted by
this Agreement, and that all conditions precedent to such amendment are satisfied. Each of the Trustee, the Custodian (if the
Certificate Administrator is then acting as Custodian) and the Certificate Administrator may, but shall not be obligated to, enter
into any such amendment which affects the Trustee’s, the Custodian’s (if the Certificate Administrator is then acting
as Custodian) or the Certificate Administrator’s, as applicable, own rights, duties or immunities under this Agreement.
Any party hereto requesting an amendment to this Agreement shall provide (x) notice of such amendment no later than 3 Business
Days prior to the anticipated date of execution, and (y) a copy of the executed amendment no later than the date of execution,
to each Other Depositor (and counsel thereto) and Other Exchange Act Reporting Party under each Other Pooling and Servicing Agreement
(which may be by email) in order for each Companion Loan Holder to timely comply with its obligations under the Exchange Act.
The party requesting an amendment to this Agreement shall provide to the Rule 17g-5 Information Provider, for posting on the Rule
17g-5 Information Provider’s Website pursuant to Section 12.13 of this Agreement, prior written notice of such
proposed amendment.


 


Section 12.08       
Confirmation of Intent. The Depositor intends that the conveyance of the Depositor’s right, title and interest
in and to the Mortgage Loans pursuant to this Agreement shall constitute a sale and not a pledge of security for a loan. If such
conveyance is deemed to be a pledge of security for a loan, however, the Depositor intends that the rights and obligations of
the parties to such loan shall be established pursuant to the terms of this Agreement.


 






    	-465- 



     


    

 


The
Depositor also intends and agrees that, in such event, (i) the Depositor shall be deemed to have granted to the Trustee (in
such capacity) a first priority security interest in the Depositor’s entire right, title and interest in and to the assets
comprising the Trust Fund, including without limitation, the Mortgage Loans, all principal and interest received or receivable
with respect to the Mortgage Loans (other than principal and interest payments due and payable prior to the Cut-Off Date and Principal
Prepayments received prior to the Cut-Off Date), all amounts held from time to time in the Collection Account, the Distribution
Account, the Excess Interest Distribution Account, the Interest Reserve Account and, if established, the Excess Liquidation Proceeds
Reserve Account and the REO Account, and all reinvestment earnings on such amounts, and all of the Depositor’s right, title
and interest in and to any Insurance Proceeds related to such Mortgage Loans and (ii) this Agreement shall constitute a security
agreement under applicable law. This Section 12.08 shall constitute notice to the Trustee pursuant to any of the requirements
of the applicable UCC.


 


Section 12.09       
Third-Party Beneficiaries. Except as provided in (i) Section 3.01(j)(iv) of this Agreement and (ii) the next
sentence, no Persons other than a party to this Agreement, any Serviced Companion Loan Holder (unless it is the Mortgagor under
the applicable Serviced Companion Loan or an Affiliate thereof) and any Certificateholder, shall have any rights with respect
to the enforcement of any of the rights or obligations hereunder. Any Underwriter or Initial Purchaser (with respect to its rights
to receive any documents, certifications, information and/or indemnification hereunder and its rights under Section 2.02,
Section 5.03 and Section 12.07 of this Agreement), any Serviced Companion Loan Holder (in respect of the
rights afforded it under this Agreement, any related Other Servicer shall be entitled to enforce the rights of such Serviced Companion
Loan Holder under this Agreement and the related Co-Lender Agreement), any Mortgage Loan Seller (with respect to its rights under
Section 2.03(a), Section 2.03(b), Section 2.03(c), Section 3.09(d)(i), Section 12.07
and Section 12.16 of this Agreement and its rights as a Privileged Person), the Retaining Sponsor (with respect to its
rights under Section 5.02(f) and Section 5.03(i)), any Other Depositor and Other Exchange Act Reporting Party
(with respect to its rights under Article X of this Agreement), any Other Servicer and Other Special Servicer (with respect
to all provisions herein expressly relating to compensation, reimbursement or indemnification of such Other Servicer or Other
Special Servicer, as the case may be, and the provisions herein regarding coordination of Advances) and, subject to Section 12.02
of this Agreement, any Certificateholder (which are intended third-party beneficiaries of this Agreement) shall have
the right to enforce their respective rights and obligations hereunder (in the case of any Serviced Companion Loan Holder, to
the extent they affect the related Serviced Companion Loan and provided that such Serviced Companion Loan Holder is not the Mortgagor
under the related Companion Loan or an Affiliate thereof) as if each such Person was a party hereto.


 


Without
limiting the foregoing, the parties to this Agreement specifically state that no Mortgagor, property manager or other party to
a Mortgage Loan is an intended third-party beneficiary of this Agreement.


 


Section 12.10       
Request by Certificateholders or the Serviced Companion Loan Holder. Where information or reports are required to
be delivered to a Certificateholder or a Serviced Companion Loan Holder, as applicable, upon request pursuant to the terms of
this Agreement, such request can be in the form of a single blanket request by a Certificateholder or a Serviced Companion Loan
Holder, as applicable, to the Certificate Administrator, the Master


 






    	-466- 



     


    

 


Servicer
or the Special Servicer, as applicable, and, with respect to such Certificateholder or a Serviced Companion Loan Holder, as applicable,
such request shall be deemed to relate to each date such report or information may be requested. The notice shall set forth the
applicable Sections where such reports and information are requested.


 


Section 12.11       
Waiver of Jury Trial. THE PARTIES HERETO HEREBY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, THE RIGHT TO TRIAL

THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

CERTIFIED MAIL ADDRESSED TO IT AS PROVIDED FOR NOTICES HEREUNDER AND AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO

Section 12.13       
Exchange Act Rule 17g-5 Procedures.


 


(a)

expenses), joint or several, to which any such Indemnified Party may become subject, under the Act, the Exchange Act or otherwise,
pursuant to a third-party claim, insofar as such losses, liabilities, damages, claims, judgments, costs, fees, penalties, fines,
forfeitures or other expenses (including reasonable legal fees and expenses) arise out of or are based upon (i) such Indemnifying
Party’s breach of Section 12.06, Section 12.13(a), Section 12.13(b), Section 12.13(c),
Section 12.13(g) or Section 12.13(h) of this Agreement or (ii) a determination by any Rating Agency that
it cannot reasonably rely on representations made by the Depositor or any Affiliate thereof pursuant to Exchange Act Rule 17g-5(a)(3),
to the extent caused by any such breach referred to in clause (i) above by the applicable Indemnifying Party, and will reimburse
such Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating
or defending any such action or claim, as such expenses are incurred. The Depositor shall notify each of the Master Servicer and
the Special Servicer in writing of any change in the identity or contact information of the Rule 17g-5 Information Provider (if
it is not also the Certificate Administrator).


 


(e)            
None of the Master Servicer, the Special Servicer, the Certificate Administrator (unless the Certificate Administrator is acting

for (i) the Rule 17g-5 Information Provider’s failure to post information provided by the Master Servicer, the Special
Servicer, the Certificate Administrator, the Trustee, the Operating Advisor or the Custodian in accordance with the terms of this
Agreement, (ii) any malfunction or disabling of the Rule 17g-5 Information Provider’s Website or (iii) such party’s

if the Rule 17g-5 Information Provider fails to notify such party that it has posted such information or communication on the
Rule 17g-5 Information Provider’s Website.


 


(f)            
None of the foregoing restrictions in this Section 12.13 prohibit or restrict oral or written communications, or providing

Servicer, as applicable, that it does not intend to use such information in undertaking credit rating surveillance for any Class
of Certificates (and the party providing such information to a Rating Agency shall, upon written request, certify to the Depositor
that it received the confirmation described in this clause (z)).


 


(g)           
The Rule 17g-5 Information Provider shall establish and maintain the Rule 17g-5 Information Provider’s Website in the form

to be. If any information is delivered or posted in error, the Rule 17g-5 Information Provider may remove


 






    	-470- 



     


    

 


it

be liable for the dissemination of information in accordance with the terms of this Agreement, makes no representations or warranties
as to the accuracy or completeness of such information being made available, and assumes no responsibility for such information.
The Rule 17g-5 Information Provider shall not be liable for its failure to make any information available to the Rating Agencies

(or by any other form of electronic delivery reasonably acceptable to Rule 17g-5 Information Provider pursuant to the terms of
this Agreement), with a subject heading of “[CGCMT 2017-C4]” and sufficient detail to indicate that such information

only be responsible for sending such notices to the electronic mail address(es) of such Registered Rating Agency as provided by
such Registered Rating Agency upon its registration as user of the Rule 17g-5 Information Provider’s Website or upon any
subsequent update of such electronic mail address(es) made by such Registered Rating Agency through the Rule 17g-5 Information
Provider’s Website, and the Rule 17g-5 Information Provider shall not be responsible for sending any notices to any electronic

(i)             
In connection with the delivery by the Master Servicer, Special Servicer, Certificate Administrator, Operating Advisor or Trustee,
as applicable, to the Rule 17g-5 Information Provider of any information, report, notice or document for posting to the Rule 17g-5
Information Provider’s Website, the Rule 17g-5 Information Provider shall notify the Master Servicer, Special Servicer,
Certificate Administrator, Operating Advisor or Trustee, as applicable, of when such information, report, notice or other document
has been posted to the Rule 17g-5 Information Provider’s Website, and the Master Servicer, Special Servicer, Certificate

17g-5 Information Provider that such information, report, notice or other document has been posted to the Rule 17g-5 Information
Provider’s Website and (b) after 12:00 p.m. on the first Business Day following the date it has provided such information,
report, notice or other document to the Rule 17g-5 Information Provider.


 


(j)             
With respect to each Outside Serviced Mortgage Loan, each of the Master Servicer, the Certificate Administrator and the Trustee
shall provide to the 17g-5 Information Provider for posting on the 17g-5 Information Provider’s Website, promptly upon receipt
from an Outside Service Provider, all reports, statements, documents, notices and other information it receives in respect of
such Outside Serviced Mortgage Loan that would otherwise have been required to be submitted to the 17g-5 Information Provider
under this Agreement for posting had such Outside Serviced Mortgage Loan been a Serviced Mortgage Loan. The 17g-5 Information
Provider shall post on the 17g-5 Information Provider’s Website all such information it receives in accordance with this
Agreement.


 


(k)           
The Master Servicer or the Special Servicer may, but shall not be obligated to, provide information to the 17g-5 Information Provider
that is neither specifically required hereunder nor requested by any Rating Agency. Any such information shall be posted by the
17g-5 Information Provider in accordance with the timeframe provided in Section 12.13(b).


 


(l)             
If any of the parties to this Agreement receives a Form ABS Due Diligence-15E from any Person in connection with any third-party
“due diligence services” (as defined in Rule 17g-10 under the Exchange Act) provided by such Person with respect to
the Mortgage Loans (“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 in accordance
with Section 12.13(h). 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,
in accordance with the timeframe provided in Section 12.13(h).


 


(m)      
     Neither the Master Servicer nor the Special Servicer shall be required to make any determination as to
whether any service provided by a third party requires obtaining a Form ABS Due Diligence-15E.


 


Section 12.14       
Cooperation with the Mortgage Loan Sellers with Respect to Rights Under the Loan Agreements. 


 






    	-472- 



     


    

 


It
is expressly agreed and understood that, notwithstanding the assignment of the Loan Documents, it is expressly intended that the
Mortgage Loan Sellers are entitled to the benefit of any securitization indemnification provisions that specifically run to the
benefit of the lenders in the Loan Documents. Therefore, the Depositor, Master Servicer, Special Servicer and Trustee hereby agree
to reasonably cooperate with any Mortgage Loan Seller, at the sole expense of such Mortgage Loan Seller, with respect to obtaining
the benefits of the provisions of any section of a Loan Agreement or securitization cooperation agreement providing for indemnification
of the lender and/or its loan seller affiliates with respect to the current securitization of the related Mortgage Loan, including,
without limitation, reassignment to the related Mortgage Loan Seller of such sections, but no other portion, of the Loan Documents,
to permit the related Mortgage Loan Seller to enforce such provisions for its benefit; provided, that none of the Depositor, Master
Servicer, Special Servicer or Trustee shall be required to take any action that is inconsistent with the Servicing Standard, would
violate applicable law, the terms and provisions of this Agreement or the Loan Documents, would adversely affect any Certificateholder,
would cause either Trust REMIC to fail to qualify as a REMIC or the Grantor Trust to fail to qualify as a grantor trust for federal
income tax purposes, or would result in the imposition of a “prohibited transaction” or “prohibited contribution”
tax under the REMIC Provisions. To the extent that the Trustee is required to execute any document facilitating an assignment
under this Section 12.14, such document shall be in form and substance reasonably acceptable to the Trustee.


 


Section 12.15       
PNC Bank, National Association


 


PNC
Bank, National Association, by execution hereof by its division, Midland Loan Services, a Division of PNC Bank, National Association,
acknowledges and agrees that this Agreement is binding upon and enforceable against PNC Bank, National Association to the full
extent of the obligations set forth herein with respect to Midland Loan Services, a Division of PNC Bank, National Association.

This certifies that
[                ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class A-1 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-2,
Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class A-1 Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 






    A-1-2 


     


    




 


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 Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling
and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class A-1 Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to


 



    A-1-3 


     


    

 


any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize 



 






    A-1-4 


     


    




 


	 	 	such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan

of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.

Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to 



 






    A-1-5 


     


    




 


	 	 	any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,

		(v)	without the consent of 100% of the Certificateholders of the Class or Classes of Certificates adversely
affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or

The Holders of the
Controlling Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do
not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice

as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to

    A-1-6

of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an

to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration

This certifies that
[                ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class A-2 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class A-2 Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 






    A-2-2 


     


    




 


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 Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling
and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class A-2 Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to


 



    A-2-3 


     


    

 


any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


This Certificate does

the interests, rights, benefits, obligations and duties evidenced hereby, and the limitations thereon, and the rights, duties and
immunities of the Certificate Administrator and Trustee.


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize 



 






    A-2-4 


     


    




 


	 	 	such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan

of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to



 






    A-2-5 


     


    




 


	 	 	any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,

not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice

as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the


 



    A-2-6 


     


    

 


Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.

This certifies that
[               ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class A-3 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class A-3 Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 






    A-3-2 


     


    




 


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 Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling
and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class A-3 Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class A-3 Certificates is the calendar
month preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.

respect of any REO Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the

the insurance policies with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing
Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments of Leases, Rents and Profits and any
security agreements; (vii) the Trustee’s rights under any indemnities or guaranties given as additional security for

		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;

the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize 



 






    A-3-4 


     


    




 


	 	 	such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;

interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further
that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner

shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.

Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator

any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to 



 






    A-3-5 


     


    




 


	 	 	any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,

not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage

such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate

    A-3-6 


     


    

 


Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets

This certifies that
[               ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class A-4 Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class A-4 Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services, a
Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 






    A-4-2 


     


    




 


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 Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling
and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class A-4 Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class A-4 Certificates is the calendar
month preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to


 



    A-4-3 


     


    

 


any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property

as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the


 



    A-4-6 


     


    

 


Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.

the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices

of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the

This certifies that
[               ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class A-AB Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class A-AB Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 






    A-5-2 


     


    




 


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 Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling
and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class A-AB Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to


 



    A-5-3 


     


    

 


any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an

		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize



 






    A-5-4 


     


    




 


	 	 	such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations

or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;

obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and

the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner

which are required to be distributed on a Certificate of any Class or to 



 






    A-5-5 


     


    




 


	 	 	any Serviced Companion Loan Holder, as applicable, without

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,

to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to

not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice

Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for in the related Co-Lender
Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s

included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and
(B) the reasonable out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage
Loans), the Special Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate
Administrator, as applicable, with respect to such termination, minus (ii) solely in the case where the Master Servicer or the

or Special Servicer, as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer,
as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the


 



    A-5-6 


     


    

 


Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.

Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master
Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein) then included
in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii) the exchange by the Remaining Certificateholder
of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the
preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer, as applicable, promptly
following receipt thereof.


 


Unless the Certificate

This certifies that
[               ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class X-A Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-AB, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class X-A Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

The initial approximate Pass-Through Rate as of the Closing Date is 1.275% per annum.



 






    A-6-2 


     


    




 


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


 


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


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, with respect to the Class X-A Certificates for
such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be
entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto;


 



    A-6-3 


     


    

 


(ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund,



 






    A-6-4 


     


    




 


	 	 	provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further
that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner

Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for in the related Co-Lender
Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s
interest in any REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any Mortgage Loan then
included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and
(B) the reasonable out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage
Loans), the Special Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate

as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by


 



    A-6-6 


     


    

 


the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices

Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master
Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein) then included
in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii) the exchange by the Remaining Certificateholder
of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the
preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer, as applicable, promptly
following receipt thereof.


 


Unless the Certificate
of Authentication on this Certificate has been executed by the Certificate Administrator or on its behalf by the Authenticating

This certifies that
[               ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class X-B Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class X-B Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

The initial approximate Pass-Through Rate as of the Closing Date is 0.381% per annum.


 


     A-7-2


     


    

 





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


 


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


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, with respect to the Class X-B Certificates for
such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be
entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto;


 



     A-7-3


     


    




 


(ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund,



 



     A-7-4


     


    

 


provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;


 





		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further
that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or
consultation rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class
Representative without the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right
to receive information under the Pooling and Servicing Agreement of the Operating Advisor without the consent of the
Operating Advisor; (C) change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or the applicable Mortgage Loan Purchase Agreement without the consent of the affected Mortgage Loan
Seller; (D) change in any manner the obligations or rights of any Underwriter or Initial Purchaser, without the consent of
the affected Underwriter or Initial Purchaser; or (E) adversely affect any Serviced Companion Loan Holder in its capacity as
such without its consent. Expenses incurred with respect to any amendment shall be borne by the party requesting such
amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting an amendment for the benefit of the
Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 



     A-7-5


     


    




 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,



 


		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and

		(v)	without the consent of 100% of the Certificateholders of the Class or Classes of Certificates adversely
affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to

The Holders of the

with such purchase).

respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the
preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer, as applicable, promptly
following receipt thereof.

This certifies that
[               ] is the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect
to the Class A-S Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class A-S Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 



     A-8-2


     

    




 


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 Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling
and Servicing Agreement.


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class A-S Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to


 



     A-8-3


     

    




 


any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize 



 



     A-8-4


     

    

 


such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;


 





		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further
that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or
consultation rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class
Representative without the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right
to receive information under the Pooling and Servicing Agreement of the Operating Advisor without the consent of the
Operating Advisor; (C) change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or the applicable Mortgage Loan Purchase Agreement without the consent of the affected Mortgage Loan
Seller; (D) change in any manner the obligations or rights of any Underwriter or Initial Purchaser, without the consent of
the affected Underwriter or Initial Purchaser; or (E) adversely affect any Serviced Companion Loan Holder in its capacity as
such without its consent. Expenses incurred with respect to any amendment shall be borne by the party requesting such
amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting an amendment for the benefit of the
Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to



 



     A-8-5


     

    

 





 any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,


 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,



 


		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and

		(v)	without the consent of 100% of the Certificateholders of the Class or Classes of Certificates adversely
affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or

The Holders of the
Controlling Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do
not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice
given to the parties (or, if applicable, the other parties) to the Pooling and Servicing Agreement (whereupon the Master Servicer
shall notify the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the Anticipated

Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for in the related Co-Lender
Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s

included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and

Loans), the Special Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate
Administrator, as applicable, with respect to such termination, minus (ii) solely in the case where the Master Servicer or the

or Special Servicer, as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer,
as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to

     A-8-6

to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an

This certifies that [           ] is
the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to
the Class B Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by
first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class C, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class B Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 



    A-9-2


     


    

 


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 Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling
and Servicing Agreement.


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate
amount of principal and interest then distributable, if any, with respect to the Class B Certificates for such Distribution Date,
all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to a share of Yield
Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the last Business Day of the month preceding the month
in which such Distribution Date occurs. Distributions are required to be made 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
to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions no
less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order
applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution on
each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections in respect
of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date in the
month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO Property
(but, with respect to


 






    A-9-3


     


    

 


any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest in the
related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property relating
to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master Servicer’s
and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be maintained pursuant
to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments of Leases,
Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties given as additional
security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s rights in the Escrow
Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, the Distribution Account,
the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds Reserve Account and any
REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental indemnity agreements
relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements to the extent
assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular Interests;
(xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize 



 



    A-9-4


     


    

 


	 	 	such
                                         risk and (2) the action will not adversely affect in any material respect the interests
                                         of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions
                                         with respect to) the transfer of the Class R Certificates, provided that the Depositor
                                         has determined that the amendment will not give rise to any tax with respect to the transfer
                                         of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary
                                         to comply with the Investment Company Act of 1940, as amended, the Exchange Act, Regulation
                                         AB, Regulation RR and/or any related regulatory actions and/or interpretations or (D)
                                         in the event that Regulation RR (or any portion thereof) or any other regulations applicable
                                         to the risk retention requirements for this securitization transaction are amended or
                                         repealed, to the extent required to comply with any such amendment or to modify or eliminate
                                         any risk retention requirements no longer applicable to this securitization transaction
                                         in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation rights or
the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without the
consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under the
Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan
Purchase Agreement without the consent of the affected Mortgage Loan Seller; (D) change in any manner the obligations or
rights of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to

                                         Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,



 


		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or the related Mortgage Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller,



 


		(iv)	change the definition of “Servicing Standard” without either (A) consent of 100% of
the holders of the Certificates or (B) Rating Agency Confirmation,



 


		(v)	without the consent of 100% of the Certificateholders of the Class or Classes of Certificates adversely
affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to

Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders, the Special
Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage Interest in
such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice given to the
parties (or, if applicable, the other parties) to the Pooling and Servicing Agreement (whereupon the Master Servicer shall notify
the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the Anticipated Termination
Date, by purchasing on such date all, but not less than all, of the Mortgage Loans (and in the case of the Serviced Loan Combinations,
subject to certain rights of the related Serviced Companion Loan Holder provided for in the related Co-Lender Agreement) then included
in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s interest in any
REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any Mortgage Loan then included in the
Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and (B) the reasonable
out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage Loans), the Special
Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate Administrator,
as applicable, with respect to such termination, minus (ii) solely in the case where the Master Servicer or the Special Servicer
is effecting such purchase, the aggregate amount of unreimbursed Advances, if any, made by the Master Servicer or Special Servicer,
as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer, as applicable, in
respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding (which items
will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection with
such purchase).


 


Any Person(s) effecting an
early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the


 






    A-9-6


     


    

 


Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices
to Certificateholders as set forth in the Pooling and Servicing Agreement and to make any required remittances to the Serviced
Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master
Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein) then included
in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii) the exchange by the Remaining Certificateholder
of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,

This certifies that [          ] is
the registered owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to
the Class C Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by
first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate
shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class X-D, Class D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class C Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

The initial approximate Pass-Through Rate as of the Closing Date is 4.344% per annum.


 


    A-10-2


     


    

 


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


 


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


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate
amount of principal and interest then distributable, if any, with respect to the Class C Certificates for such Distribution Date,
all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to a share of Yield
Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the last Business Day of the month preceding the month
in which such Distribution Date occurs. Distributions are required to be made 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
to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions no
less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order
applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution on
each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement, together with the Mortgage Files relating thereto;


 






    A-10-3


     


    

 


(ii) all scheduled or unscheduled payments on or collections in respect
of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date in the
month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO Property
(but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest in the
related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property relating
to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master Servicer’s
and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be maintained pursuant
to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments of Leases,
Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties given as additional
security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s rights in the Escrow
Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, the Distribution Account,
the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds Reserve Account and any
REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental indemnity agreements
relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements to the extent
assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular Interests;
(xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, 



 



    A-10-4


     


    

 


	 	 	provided
                                         that the Trustee and the Certificate Administrator have received an opinion of counsel
                                         (at the expense of the party requesting the amendment) to the effect that (1) the action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize such
                                         risk and (2) the action will not adversely affect in any material respect the interests
                                         of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions
                                         with respect to) the transfer of the Class R Certificates, provided that the Depositor
                                         has determined that the amendment will not give rise to any tax with respect to the transfer
                                         of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary
                                         to comply with the Investment Company Act of 1940, as amended, the Exchange Act, Regulation
                                         AB, Regulation RR and/or any related regulatory actions and/or interpretations or (D)
                                         in the event that Regulation RR (or any portion thereof) or any other regulations applicable
                                         to the risk retention requirements for this securitization transaction are amended or
                                         repealed, to the extent required to comply with any such amendment or to modify or eliminate
                                         any risk retention requirements no longer applicable to this securitization transaction
                                         in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation rights or
the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without the
consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under the
Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan
Purchase Agreement without the consent of the affected Mortgage Loan Seller; (D) change in any manner the obligations or
rights of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 



    A-10-5


     


    

 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,



 


		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or the related Mortgage Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller,

the holders of the Certificates or (B) Rating Agency Confirmation,



 


		(v)	without the consent of 100% of the Certificateholders of the Class or Classes of Certificates adversely
affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,

The Holders of the Controlling
Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do not, the Special
Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders, the Special
Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage Interest in
such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice given to the
parties (or, if applicable, the other parties) to the Pooling and Servicing Agreement (whereupon the Master Servicer shall notify
the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the Anticipated Termination
Date, by purchasing on such date all, but not less than all, of the Mortgage Loans (and in the case of the Serviced Loan Combinations,
subject to certain rights of the related Serviced Companion Loan Holder provided for in the related Co-Lender Agreement) then included
in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s interest in any
REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any Mortgage Loan then included in the
Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and (B) the reasonable
out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage Loans), the Special
Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate Administrator,
as applicable, with respect to such termination, minus (ii) solely in the case where the Master Servicer or the Special Servicer
is effecting such purchase, the aggregate amount of unreimbursed Advances, if any, made by the Master Servicer or Special Servicer,
as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer, as applicable, in
respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding (which items
will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection with
such purchase).


 


Any Person(s) effecting an
early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by


 






    A-10-6


     


    

 


the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices
to Certificateholders as set forth in the Pooling and Servicing Agreement and to make any required remittances to the Serviced
Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master
Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein) then included
in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii) the exchange by the Remaining Certificateholder
of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the
preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer, as applicable, promptly
following receipt thereof.


 


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 Pooling and Servicing Agreement or be valid
for any purpose.

Class J-RR, Class R and Class S Certificates (together with the Class X-D Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 


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


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate
amount of interest then distributable, if any, with respect to the Class X-D Certificates for such Distribution Date, all as more
fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to a share of Yield Maintenance
Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the last Business Day of the month preceding the month
in which such Distribution Date occurs. Distributions are required to be made 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
to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions no
less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order
applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution on
each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held.


 






    A-11-4


     


    

 


Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections in respect
of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date in the
month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO Property
(but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest in the
related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property relating
to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master Servicer’s
and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be maintained pursuant
to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments of Leases,
Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties given as additional
security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s rights in the Escrow
Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, the Distribution Account,
the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds Reserve Account and any
REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental indemnity agreements
relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements to the extent
assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular Interests;
(xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 



    A-11-5


     


    

 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that no amendment
pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation rights or the right to
receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without the consent of the
Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under the Pooling and
Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner the obligations
or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan Purchase Agreement
without the consent of the affected Mortgage Loan Seller; (D) change in any manner the obligations or rights of any Underwriter
or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely affect any Serviced
Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment shall be borne
by the party requesting such amendment, unless the Master


 






    A-11-6


     


    

 


Servicer, the Special Servicer or the Trustee is requesting an amendment
for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,



 


		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or the related Mortgage Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller,

		(v)	without the consent of 100% of the Certificateholders of the Class or Classes of Certificates adversely
affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or



 


		(viii)	change in any manner the obligations or rights of any Underwriter or Initial Purchaser without
the consent of the affected Underwriter or Initial Purchaser.



 


The Holders of the Controlling
Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do not, the Special
Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders, the Special
Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage Interest in
such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice given to the
parties (or, if applicable, the other parties) to the Pooling and Servicing Agreement (whereupon the Master Servicer shall notify
the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the Anticipated Termination
Date, by purchasing on such date all, but not less than all, of the Mortgage Loans (and in the case of the Serviced Loan Combinations,
subject to certain rights of the related Serviced Companion Loan Holder provided for in the related Co-Lender Agreement) then included
in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s interest in any
REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any Mortgage Loan then included in the
Trust Fund, at a purchase price,


 






    A-11-7


     


    

 


payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and (B) the reasonable
out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage Loans), the Special
Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate Administrator,
as applicable, with respect to such termination, minus (ii) solely in the case where the Master Servicer or the Special Servicer
is effecting such purchase, the aggregate amount of unreimbursed Advances, if any, made by the Master Servicer or Special Servicer,
as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer, as applicable, in
respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding (which items
will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection with
such purchase).


 


Any Person(s) effecting an
early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices
to Certificateholders as set forth in the Pooling and Servicing Agreement and to make any required remittances to the Serviced
Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master
Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein) then included
in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii) the exchange by the Remaining Certificateholder
of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the
preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer, as applicable, promptly
following receipt thereof.

and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict

Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class E-RR, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class D Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is issued
pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 


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


 


Pursuant to the terms of the
Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any Certificate),
on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date, a “Distribution
Date”), to the Person in whose name this Certificate is registered as of the related Record Date, an amount equal to
such Person’s pro rata share (based on the Percentage Interest represented by this Certificate) of that portion of the aggregate
amount of principal and interest then distributable, if any, with respect to the Class D Certificates for such Distribution Date,
all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may be entitled to a share of Yield
Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions (other than
the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names the Certificates
are registered at the close of business on each Record Date, which will be the last Business Day of the month preceding the month
in which such Distribution Date occurs. Distributions are required to be made 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
to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions no
less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order
applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution on
each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of


 






    A-12-4


     


    

 


maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the Pooling
and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling and Servicing
Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections in respect
of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date in the
month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO Property
(but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest in the
related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property relating
to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master Servicer’s
and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be maintained pursuant
to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments of Leases,
Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties given as additional
security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s rights in the Escrow
Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, the Distribution Account,
the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds Reserve Account and any
REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental indemnity agreements
relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements to the extent
assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular Interests;
(xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 



    A-12-5


     


    

 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation rights or
the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without the
consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under the
Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan
Purchase Agreement without the consent of the affected Mortgage Loan Seller; (D) change in any manner the obligations or
rights of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master


 






    A-12-6


     


    

 


Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,



 


		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or the related Mortgage Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller,



 


		(iv)	change the definition of “Servicing Standard” without either (A) consent of 100% of
the holders of the Certificates or (B) Rating Agency Confirmation,



 


		(v)	without the consent of 100% of the Certificateholders of the Class or Classes of Certificates adversely
affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or



 


		(viii)	change in any manner the obligations or rights of any Underwriter or Initial Purchaser without
the consent of the affected Underwriter or Initial Purchaser.



 


The Holders of the Controlling
Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do not, the Special
Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders, the Special
Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage Interest in
such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice given to the
parties (or, if applicable, the other parties) to the Pooling and Servicing Agreement (whereupon the Master Servicer shall notify
the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the Anticipated Termination
Date, by purchasing on such date all, but not less than all, of the Mortgage Loans (and in the case of the Serviced Loan Combinations,
subject to certain rights of the related Serviced Companion Loan Holder provided for in the related Co-Lender Agreement) then included
in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s interest in any
REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any Mortgage Loan then included in the
Trust Fund, at a purchase price,


 






    A-12-7


     


    

 


payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and (B) the reasonable
out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage Loans), the Special
Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate Administrator,
as applicable, with respect to such termination, minus (ii) solely in the case where the Master Servicer or the Special Servicer
is effecting such purchase, the aggregate amount of unreimbursed Advances, if any, made by the Master Servicer or Special Servicer,
as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer, as applicable, in
respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding (which items
will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection with
such purchase).


 


Any Person(s) effecting an
early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices
to Certificateholders as set forth in the Pooling and Servicing Agreement and to make any required remittances to the Serviced
Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master
Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein) then included
in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii) the exchange by the Remaining Certificateholder
of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the
preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer, as applicable, promptly
following receipt thereof.


 


Unless the Certificate of

was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate

inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class F-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class E-RR Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 


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


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class E-RR Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps


 



    A-13-4


    


    

 


to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 






    A-13-5


    


    

 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further
that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan

    A-13-6


    


    

 


rights of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,



 


		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and

affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or

The Holders of the
Controlling Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do
not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice

Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for


 



    A-13-7


    


    

 


in the related Co-Lender
Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s
interest in any REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any Mortgage Loan then
included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and
(B) the reasonable out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage
Loans), the Special Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate

or Special Servicer, as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer,
as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,

Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master

of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the
preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer, as applicable, promptly
following receipt thereof.

was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate

inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR,
Class G-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class F-RR Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 


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


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class F-RR Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps


 



    A-14-4


    


    

 


to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 






    A-14-5


    


    

 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan

rights of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,

affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or



 


		(viii)	change in any manner the obligations or rights of any Underwriter or Initial Purchaser without

The Holders of the
Controlling Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do
not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice
given to the parties (or, if applicable, the other parties) to the Pooling and Servicing Agreement (whereupon the Master Servicer
shall notify the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the Anticipated

Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for


 



    A-14-7


    


    

 


in the related Co-Lender
Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s
interest in any REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any Mortgage Loan then
included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and
(B) the reasonable out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage
Loans), the Special Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate
Administrator, as applicable, with respect to such termination, minus (ii) solely in the case where the Master Servicer or the
Special Servicer is effecting such purchase, the aggregate amount of unreimbursed Advances, if any, made by the Master Servicer
or Special Servicer, as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer,
as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices
to Certificateholders as set forth in the Pooling and Servicing Agreement and to make any required remittances to the Serviced
Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master
Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein) then included
in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii) the exchange by the Remaining Certificateholder
of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration
of twenty-one years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the United Kingdom, living on the date of the Pooling and Servicing Agreement. All such payments as contemplated by the
preceding paragraph shall be deposited into the Collection Account by the Master Servicer or Special Servicer, as applicable, promptly
following receipt thereof.

to the Class G-RR Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict
between any provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate

inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR,
Class F-RR, Class H-RR, Class J-RR, Class R and Class S Certificates (together with the Class G-RR Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 


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


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class G-RR Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps


 



     A-15-4


     


    

 


to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 






     A-15-5


     


    

 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan
Purchase Agreement without the consent of the affected Mortgage Loan Seller; (D) change in any manner the obligations or


 



     A-15-6


     


    

 


rights of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,

or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or

Controlling Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do
not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice

Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for


 



     A-15-7


     


    

 


in the related Co-Lender
Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund (including the Trust Fund’s
interest in any REO Property acquired with respect to any Outside Serviced Mortgage Loan) in respect of any Mortgage Loan then
included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A) the Termination Purchase Amount and
(B) the reasonable out-of-pocket expenses of the Master Servicer (unless the Master Servicer is the purchaser of such Mortgage
Loans), the Special Servicer (unless the Special Servicer is the purchaser of such Mortgage Loans), the Trustee and the Certificate

or Special Servicer, as applicable, together with any interest accrued and payable to the Master Servicer or the Special Servicer,
as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets
of the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement shall be borne by the party exercising its
purchase rights thereunder. The Certificate Administrator shall be entitled to rely conclusively on any determination made by an
Appraiser pursuant to Section 9.01(c) of the Pooling and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices
to Certificateholders as set forth in the Pooling and Servicing Agreement and to make any required remittances to the Serviced
Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master

of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,
however, that in no event shall the trust created by the Pooling and Servicing Agreement continue beyond the expiration

was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict

inconsistency.
Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A,
Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR, Class G-RR, Class J-RR, Class R and Class
S Certificates (together with the Class H-RR Certificates, the “Certificates”; the Holders of Certificates
are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 


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


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class H-RR Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to
surrender their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto.
If within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps 


 



     A-16-4


     


    




 


to
contact the remaining Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining such
funds and of contacting Certificateholders shall be paid out of the assets which remain held. Subject to applicable state law
with respect to escheatment of funds, if within two years after the second notice any Certificates shall not have been surrendered
for cancellation, the Paying Agent shall pay to the Class R Certificateholders all amounts distributable to the Holders thereof.
No interest shall accrue or be payable to any Certificateholder on any amount held as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 9.01 of the Pooling and Servicing
Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 






     A-16-5


     


    

 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further
that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation rights
or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without the
consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under the
Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage
Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan Purchase Agreement without the consent of
the affected Mortgage Loan Seller; (D) change in any manner the obligations or


 






     A-16-6


     


    

 


 rights of any Underwriter or Initial Purchaser,
without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely affect any Serviced Companion Loan Holder
in its capacity as such without its consent. Expenses incurred with respect to any amendment shall be borne by the party requesting
such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting an amendment for the benefit of
the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,

or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or

The Holders of the
Controlling Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do
not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice
given to the parties (or, if applicable, the other parties) to the Pooling and Servicing Agreement (whereupon the Master Servicer
shall notify the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the Anticipated

Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for


 






     A-16-7


     


    

 





in
the related Co-Lender Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund
(including the Trust Fund’s interest in any REO Property acquired with respect to any Outside Serviced Mortgage Loan) in
respect of any Mortgage Loan then included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A)
the Termination Purchase Amount and (B) the reasonable out-of-pocket expenses of the Master Servicer (unless the Master Servicer
is the purchaser of such Mortgage Loans), the Special Servicer (unless the Special Servicer is the purchaser of such Mortgage
Loans), the Trustee and the Certificate Administrator, as applicable, with respect to such termination, minus (ii) solely in the
case where the Master Servicer or the Special Servicer is effecting such purchase, the aggregate amount of unreimbursed Advances,
if any, made by the Master Servicer or Special Servicer, as applicable, together with any interest accrued and payable to the
Master Servicer or the Special Servicer, as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing
Fees, as applicable, remaining outstanding (which items will be deemed to have been paid or reimbursed to the Master Servicer
or the Special Servicer, as applicable, in connection with such purchase).


 


Any Person(s)
effecting an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class
Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R
Certificate, notify the Certificate Administrator (who shall notify the Controlling Class Representative and each Certifying
Certificateholder) of its intention to do so in writing at least 30 days prior to the Anticipated Termination Date. All costs
and expenses incurred by any and all parties to the Pooling and Servicing Agreement or by the Trust Fund in connection with
the purchase of the Mortgage Loans and other assets of the Trust Fund pursuant to Section 9.01(c) of the Pooling and
Servicing Agreement shall be borne by the party exercising its purchase rights thereunder. The Certificate Administrator
shall be entitled to rely conclusively on any determination made by an Appraiser pursuant to Section 9.01(c) of the Pooling
and Servicing Agreement.


 


The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, the Asset Representations
Reviewer, the Certificate Administrator and the Trustee created by the Pooling and Servicing Agreement with respect to the Certificates,
the Mortgage Loans and the Serviced Companion Loans (other than the obligation to make certain payments and to send certain notices
to Certificateholders as set forth in the Pooling and Servicing Agreement and to make any required remittances to the Serviced
Companion Loan Holders in the month in which the final Distribution Date occurs and certain tax-related obligations) shall terminate
immediately following the earlier to occur of (i) the purchase by Holders of the Controlling Class, the Special Servicer, the Master
Servicer or Holders of the Class R Certificates of all the Mortgage Loans and REO Properties (or interests therein) then included
in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii) the exchange by the Remaining Certificateholder
of its Certificates for all the Mortgage Loans and REO Properties (or interests therein) then included in the Trust Fund pursuant
to Section 9.01(h) of the Pooling and Servicing Agreement and (iii) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property (or interest therein) contained in the Trust Fund; provided,

to the Class J-RR Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured
by first liens on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other
than in the case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund
was created, and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling
and Servicing Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the
terms, provisions and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict

inconsistency.
Also issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-AB, Class X-A,
Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class F-RR, Class G-RR, Class H-RR, Class R and Class
S Certificates (together with the Class J-RR Certificates, the “Certificates”; the Holders of Certificates
are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


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


 


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


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, with respect to the Class J-RR Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to a share of Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.


 


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


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps


 






    A-17-4


     


    




 


to
contact the remaining Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining such
funds and of contacting Certificateholders shall be paid out of the assets which remain held. Subject to applicable state law
with respect to escheatment of funds, if within two years after the second notice any Certificates shall not have been surrendered
for cancellation, the Paying Agent shall pay to the Class R Certificateholders all amounts distributable to the Holders thereof.
No interest shall accrue or be payable to any Certificateholder on any amount held as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 9.01 of the Pooling and Servicing
Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements
to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular
Interests; (xii) the Loss of Value Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


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


 


The Pooling and Servicing
Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator is then acting as Custodian),
the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or, as applicable, any Companion
Loan Holder:


 


		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates;



 






    A-17-5


     


    

 


		(ii)	to correct or supplement any of its provisions which may be inconsistent with any other provisions
of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or to correct any error;



 


		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Excess Liquidation
Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the
qualification of either Trust REMIC as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition
of any tax on the Trust Fund, provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at
the expense of the party requesting the amendment) to the effect that (1) the action is necessary or desirable to maintain such
qualification or to avoid or minimize such risk and (2) the action will not adversely affect in any material respect the interests
of any holder of the Certificates, (B) to restrict (or to remove any existing restrictions with respect to) the transfer of the
Class R Certificates, provided that the Depositor has determined that the amendment will not give rise to any tax with respect
to the transfer of the Class R Certificates to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment
Company Act of 1940, as amended, the Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations
or (D) in the event that Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements
for this securitization transaction are amended or repealed, to the extent required to comply with any such amendment or to modify
or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;



 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner
the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Mortgage Loan
Purchase Agreement without the consent of the affected Mortgage Loan Seller; (D) change in any manner the obligations or


 






    A-17-6


     


    

 


rights of any Underwriter
or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely affect any Serviced
Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment shall be borne
by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting an amendment
for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 


		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Serviced Loans
which are required to be distributed on a Certificate of any Class or to any Serviced Companion Loan Holder, as applicable, without
the consent of the Holder of that Certificate or that Serviced Companion Loan Holder, as applicable,



 


		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment without the consent of the Holders of all Certificates of that Class then outstanding,



 


		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or the related Mortgage Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller,

		(v)	without the consent of 100% of the Certificateholders of the Class or Classes of Certificates adversely
affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to
the Pooling and Servicing Agreement,



 


		(vi)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders,



 


		(vii)	adversely affect a Serviced Companion Loan Holder in its capacity as such without its consent,
or



 


		(viii)	change in any manner the obligations or rights of any Underwriter or Initial Purchaser without
the consent of the affected Underwriter or Initial Purchaser.



 


The Holders of the
Controlling Class representing greater than 50% of the Certificate Balance of the Controlling Class may (or, if such Holders do
not, the Special Servicer, or if neither such Holders nor the Special Servicer do, the Master Servicer or, if none of such Holders,
the Special Servicer or the Master Servicer does, any Holders of Class R Certificates representing greater than a 50% Percentage
Interest in such Class, may also) effect an early termination of the Trust Fund, upon not less than 30 days’ prior notice
given to the parties (or, if applicable, the other parties) to the Pooling and Servicing Agreement (whereupon the Master Servicer
shall notify the Serviced Companion Loan Holders) any time on or after the Early Termination Notice Date specifying the Anticipated
Termination Date, by purchasing on such date all, but not less than all, of the Mortgage Loans (and in the case of the Serviced
Loan Combinations, subject to certain rights of the related Serviced Companion Loan Holder provided for


 






    A-17-7


     


    

 


in
the related Co-Lender Agreement) then included in the Trust Fund, and all property acquired by or on behalf of the Trust Fund
(including the Trust Fund’s interest in any REO Property acquired with respect to any Outside Serviced Mortgage Loan) in
respect of any Mortgage Loan then included in the Trust Fund, at a purchase price, payable in cash, equal to (i) the sum of (A)
the Termination Purchase Amount and (B) the reasonable out-of-pocket expenses of the Master Servicer (unless the Master Servicer
is the purchaser of such Mortgage Loans), the Special Servicer (unless the Special Servicer is the purchaser of such Mortgage
Loans), the Trustee and the Certificate Administrator, as applicable, with respect to such termination, minus (ii) solely in the
case where the Master Servicer or the Special Servicer is effecting such purchase, the aggregate amount of unreimbursed Advances,
if any, made by the Master Servicer or Special Servicer, as applicable, together with any interest accrued and payable to the
Master Servicer or the Special Servicer, as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing
Fees, as applicable, remaining outstanding (which items will be deemed to have been paid or reimbursed to the Master Servicer
or the Special Servicer, as applicable, in connection with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate, notify the Certificate
Administrator (who shall notify the Controlling Class Representative and each Certifying Certificateholder) of its intention to
do so in writing at least 30 days prior to the Anticipated Termination Date. All costs and expenses incurred by any and all parties
to the Pooling and Servicing Agreement or by the Trust Fund in connection with the purchase of the Mortgage Loans and other assets

	 Percentage Interest: [ ]%	 
	 	 
	Cut-Off Date: With respect to each Mortgage Loan, the Due Date in October 2017 for that Mortgage Loan (or, in the case of any Mortgage Loan that has its first Due Date subsequent to October 2017, the date that would have been its Due Date in October 2017 under the terms of that Mortgage Loan if a Monthly Payment were scheduled to be due in that month).

This certifies that
[          ] is the registered owner of an interest in a Trust Fund, including the distributions to be made with respect to the Class R
Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens
on commercial, multifamily and manufactured housing community properties and held in trust by the Trustee and, other than in the
case of the Outside Serviced Mortgage Loans, serviced by the Master Servicer and the Special Servicer. The Trust Fund was created,
and the Mortgage Loans (other than the Outside Serviced Mortgage Loans) are to be serviced, pursuant to the Pooling and Servicing
Agreement (as defined below). The Holder of this Certificate, by virtue of the acceptance hereof, assents to the terms, provisions
and conditions of the Pooling and Servicing Agreement and is bound thereby. In the event that there is any conflict between any
provision of this Certificate and any provision of the Pooling and Servicing Agreement, such provision of this Certificate shall
be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1, Class
A-2, Class A-3, Class A-4, Class A-AB, Class X-A, Class X-B, Class A-S, Class B, Class C, Class X-D, Class D, Class E-RR, Class
F-RR, Class G-RR, Class H-RR, Class J-RR and Class S Certificates (together with the Class R Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).


 


This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.


 


This Certificate represents
the “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.


 


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 Mortgage Loans and has executed this Certificate in its limited capacity as Certificate Administrator under the Pooling
and Servicing Agreement.


 






    A-18-3


     


    




 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of the aggregate amount, if any, with respect to the Class R Certificates for such Distribution Date, all as more fully described
in the Pooling and Servicing Agreement.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan Combination); (iv) all revenues received in respect of any REO Property (but, with respect to any REO Property
relating to a Loan Combination, only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master
Servicer’s and the Trustee’s rights under the insurance policies with respect to the Mortgage Loans required to be
maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments
of Leases, Rents and Profits and any security agreements; (vii) the Trustee’s rights under any indemnities or guaranties
given as additional security for any Mortgage Loan; (viii) all of the Trustee’s and the Certificate Administrator’s
rights in the Escrow Accounts and Lock-Box Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account,
the Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Excess Liquidation Proceeds
Reserve Account and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights in any environmental
indemnity agreements relating to the


 






    A-18-4


     


    

 


 


Mortgaged
Properties; (x) the Depositor’s rights under the Mortgage Loan Purchase Agreements to the extent assigned to the Trustee
pursuant to Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular Interests; (xii) the Loss of Value
Reserve Fund; and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


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


 


Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Trustee,
the Certificate Administrator, 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 the Pooling
and Servicing Agreement and for all other purposes whatsoever, and neither the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator, the Certificate Registrar, nor any agent of any of them shall be affected

Proceeds Reserve Account, the Excess Interest Distribution Account, the Distribution Account or any REO Account, provided that
(A) the Master Servicer Remittance Date shall in no event be later than the Business Day prior to the related Distribution Date
and (B) the change would not adversely affect in any material respect the interests of any Certificateholder, as evidenced by an
opinion of counsel (at the expense of the party requesting the amendment);



 


		(iv)	to
modify, eliminate or add to any of its provisions (A) to the extent necessary to maintain the qualification of either Trust REMIC
as a REMIC or the Grantor Trust as a grantor trust or to avoid or minimize the risk of imposition of any tax on the Trust Fund,
provided that the Trustee and the Certificate Administrator have received an opinion of counsel (at the expense of the party requesting
the amendment) to the effect that (1) the action is necessary or desirable to maintain such qualification or to avoid or minimize
such risk and (2) the action will not adversely affect in any material respect the interests of any holder of the Certificates,
(B) to restrict (or to remove any existing restrictions with respect to) the transfer of the Class R Certificates, provided that
the Depositor has determined that the amendment will not give rise to any tax with respect to the transfer of the Class R Certificates
to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment Company Act of 1940, as amended, the
Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations or (D) in the event that
Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements for this securitization
transaction are amended or repealed, to the extent required to comply with any such

                                                                                




 






    A-18-5


     


    

 


amendment or to modify or eliminate any risk retention requirements no longer applicable to this securitization transaction in light of such repeal;


 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further
that no amendment pursuant to any of clauses (i)-(vii) above may be made that would: (A) reduce the consent or consultation
rights or the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change in any manner

of any Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (E) adversely
affect any Serviced Companion Loan Holder in its capacity as such without its consent. Expenses incurred with respect to any amendment
shall be borne by the party requesting such amendment, unless the Master Servicer, the Special Servicer or the Trustee is requesting
an amendment for the benefit of the Certificateholders, then in which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying
in any manner the rights of the Certificateholders; provided, however, that no such amendment shall:


 






    A-18-6

affected thereby, change (A) the percentages of Voting Rights of Certificateholders which are required to consent to any action
or inaction under the Pooling and Servicing Agreement, (B) the right of the Certificateholders to remove the Special Servicer pursuant
to the Pooling and Servicing Agreement or (C) the right of the Certificateholders to terminate the Operating Advisor pursuant to

as applicable, in respect of such Advances and any unpaid Servicing Fees or Special Servicing Fees, as applicable, remaining outstanding
(which items will be deemed to have been paid or reimbursed to the Master Servicer or the Special Servicer, as applicable, in connection
with such purchase).


 


Any Person(s) effecting
an early termination of the Trust Fund as provided in the prior paragraph shall first notify the Controlling Class Representative
and each Certifying Certificateholder, or, in the case of a termination by


 






    A-18-7


     


    

 


the
Holder of a Class R Certificate, notify the Certificate Administrator (who shall notify the Controlling Class Representative and
each Certifying Certificateholder) of its intention to do so in writing at least 30 days prior to the Anticipated Termination

shall be superseded to the extent of such inconsistency. Also issued under the Pooling and Servicing Agreement are the Class A-1,

and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating

This Certificate represents
a beneficial ownership interest in certain assets of a grantor trust consisting primarily of any Excess Interest collected on the
ARD Mortgage Loans and amounts held from time to time in the Excess Interest Distribution Account. Each Holder of this Certificate,
by acceptance hereof, agrees to treat, and take no action inconsistent with the treatment of, this Certificate in accordance with
the preceding sentence for purposes of federal income taxes, state and local income and franchise taxes and other taxes imposed
on or measured by income.


 


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


 


Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the Determination Date in each month, commencing in November 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of the aggregate amount then distributable, if any, with respect to the Class S Certificates for such Distribution Date, all as
more fully described in the Pooling and Servicing Agreement.


 


All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the last Business Day of the month
preceding the month in which such Distribution Date occurs. Distributions are required to be made 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 to accept such funds, if such Certificateholder has provided the Certificate Administrator with written wiring instructions
no less than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing
order applicable to all subsequent distributions), or otherwise by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentation 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 a notice to Certificateholders of the pendency of the final distribution.


 


Any funds not distributed
on the Termination Date because of the failure of any Certificateholders to tender their Certificates shall be set aside and held
in trust for the account of the appropriate non-tendering Certificateholders, whereupon the Trust Fund shall terminate. If any
Certificates as to which notice of the Termination Date has been given pursuant to Section 9.01 of the Pooling and Servicing Agreement
shall not have been surrendered for cancellation within six months after the time specified in such notice, the Certificate Administrator
shall mail a second notice to the remaining Certificateholders, at their last addresses shown in the Certificate Register, to surrender
their Certificates for cancellation in order to receive, from such funds held, the final distribution with respect thereto. If
within one year after the second notice any Certificate shall not have been surrendered for cancellation, the Certificate Administrator
may, directly or through an agent, take appropriate steps to contact the remaining Certificateholders concerning surrender of their
Certificates. The costs and expenses of maintaining such funds and of contacting Certificateholders shall be paid out of the assets
which remain held. Subject to applicable state law with respect to escheatment of funds, if within two years after the second notice
any Certificates shall not have been surrendered for cancellation, the Paying Agent shall pay to the Class R Certificateholders
all amounts distributable to the Holders thereof. No interest shall accrue or be payable to any Certificateholder on any amount
held as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement.


 


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


 


As provided in the
Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject to the Pooling
and Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all scheduled or unscheduled payments on or collections
in respect of the Mortgage Loans due after the Cut-Off Date or, with respect to a Qualified Substitute Mortgage Loan, the Due Date
in the month of substitution (exclusive of interest relating to periods prior to, but due after, the Cut-Off Date); (iii) any REO
Property (but, with respect to any REO Property relating to a Loan Combination, only to the extent of the Trust’s interest
in the related Loan


 






    A-19-3


     


    

 


Combination);
(iv) all revenues received in respect of any REO Property (but, with respect to any REO Property relating to a Loan Combination,
only to the extent of the Trust’s interest in the related Loan Combination); (v) the Master Servicer’s and the Trustee’s
rights under the insurance policies with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing
Agreement and any proceeds thereof; (vi) the Trustee’s rights in any Assignments of Leases, Rents and Profits and any security
agreements; (vii) the Trustee’s rights under any indemnities or guaranties given as additional security for any Mortgage
Loan; (viii) all of the Trustee’s and the Certificate Administrator’s rights in the Escrow Accounts and Lock-Box Accounts
and all proceeds of the Mortgage Loans deposited in the Collection Account, the Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Excess Liquidation Proceeds Reserve Account and any REO Account, including any reinvestment
income thereon; (ix) the Trustee’s rights in any environmental indemnity agreements relating to the Mortgaged Properties;
(x) the Depositor’s rights under the Mortgage Loan Purchase Agreements to the extent assigned to the Trustee pursuant to
Section 2.01 of the Pooling and Servicing Agreement; (xi) the Lower-Tier Regular Interests; (xii) the Loss of Value Reserve Fund;
and (xiii) the Initial Month’s Interest Deposit Amount.


 


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


 


As provided in the
Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender for registration
of transfer of any Certificate, the Certificate Administrator shall execute, authenticate and deliver, in the name of the designated

Advisor, the Trustee, the Certificate Administrator, the Certificate Registrar, nor any agent of any of them shall be affected
by any notice to the contrary.

the amendment) to the effect that (1) the action is necessary or desirable to maintain such qualification or to avoid or minimize

such
risk and (2) the action will not adversely affect in any material respect the interests of any holder of the Certificates, (B)
to restrict (or to remove any existing restrictions with respect to) the transfer of the Class R Certificates, provided that the
Depositor has determined that the amendment will not give rise to any tax with respect to the transfer of the Class R Certificates
to a non-Permitted Transferee, (C) to the extent necessary to comply with the Investment Company Act of 1940, as amended, the
Exchange Act, Regulation AB, Regulation RR and/or any related regulatory actions and/or interpretations or (D) in the event that
Regulation RR (or any portion thereof) or any other regulations applicable to the risk retention requirements for this securitization
transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate any risk
retention requirements no longer applicable to this securitization transaction in light of such repeal;


 


		(v)	to make any other provisions with respect to matters or questions arising under the Pooling and
Servicing Agreement or any other change, provided that the amendment will not adversely affect in any material respect the
interests of any Certificateholder, as evidenced by an opinion of counsel;



 


		(vi)	to modify the procedures in the Pooling and Servicing Agreement relating to Rule 17g-5; provided
that such modification does not increase the obligations of the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer, the Master Servicer or the Special Servicer without such party’s consent (which consent
may not be withheld unless such modification would materially adversely affect such party or materially increase such party’s
obligations under the Pooling and Servicing Agreement); provided, further that notice of such modification is provided
to all parties to the Pooling and Servicing Agreement; and



 


		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the ratings assigned to each Class of Certificates by any of the Rating Agencies, provided that the amendment will
not adversely affect in any material respect the interests of any Certificateholder;



 


provided, further that no

the right to receive information under the Pooling and Servicing Agreement of the Controlling Class Representative without
the consent of the Controlling Class Representative; (B) reduce the consultation rights or the right to receive information
under the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (C) change

Expenses incurred with respect to any amendment shall be borne by the party requesting such amendment, unless the Master
Servicer, the Special Servicer or the Trustee is requesting an amendment for the benefit of the Certificateholders, then in
which case such expense will be borne by the Trust.


 


The Pooling and Servicing
Agreement or any Custodial Agreement may also be amended from time to time by a writing signed by each of the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Custodian (if the Certificate Administrator
is then acting as Custodian), the Certificate Administrator and the Trustee with the consent of the Holders of Certificates representing
not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying

applicable, in connection with such purchase).


 


Any Person(s) effecting

Capitalized terms not
defined herein shall have the meaning ascribed to them in the Pooling and Servicing Agreement.


 


I, [______], under penalties
of perjury, declare that, to the best of my knowledge and belief, the following representations are true, correct and complete,
and being first sworn, depose and say that:


 


1.           I
am a [______] of [______] (the “Purchaser”),
on behalf of which I have the authority to make this affidavit.


 


2.           The
Purchaser is acquiring Class R Certificates representing [__]% of the residual interest in each of the real estate mortgage investment
conduits (each, a “REMIC”) designated as the
“Lower-Tier REMIC” and “Upper-Tier
REMIC,” respectively, relating to the


 



    L-1-1 


     


    

 


Certificates for which an election is to be or has been made under Section
860D of the Internal Revenue Code of 1986 (the “Code”).


 


3.           The
Purchaser is not a “Disqualified Organization”
(as defined below), and that the Purchaser is not acquiring the Class R Certificates for the account of, or as agent or nominee
of, or with a view to the transfer of direct or indirect record or beneficial ownership thereof, to a Disqualified Organization.
For the purposes hereof, a Disqualified Organization is any of the following: (i) the United States, a State or any political subdivision
of a State, any possession of the United States or any agency or instrumentality of any of the foregoing (other than an instrumentality
that is a corporation if all of its activities are subject to tax and, except for the Federal Home Loan Mortgage Corporation, a
majority of its board of directors is not selected by any such governmental unit), (ii) a foreign government, International Organization
or agency or instrumentality of either of the foregoing, (iii) an organization that is exempt from tax imposed by Chapter 1 of
the Code (including the tax imposed by Code Section 511 on unrelated business taxable income) on any excess inclusions (as defined
in Code Section 860E(c)(1)) with respect to the Class R Certificates (except certain farmers’ cooperatives described in Code
Section 521), (iv) rural electric and telephone cooperatives described in Code Section 1381(a)(2) or (v) any other Person so designated
by the Certificate Registrar based upon an opinion of counsel to the effect that any transfer to such Person may cause either Trust
REMIC to be subject to tax or to fail to qualify as a REMIC at any time that the Certificates are outstanding. The terms “United
States”, “State” and “international
organization” shall have the meanings set forth in Section 7701 of the Code.


 


4.           The
Purchaser acknowledges that Section 860E(e) of the Code would impose a substantial tax on the transferor or, in certain circumstances,
on an agent for the transferee, with respect to any transfer of any interest in any Class R Certificates to a Disqualified Organization.


 


5.           The
Purchaser is a Permitted Transferee. For the purpose hereof, a “Permitted Transferee” is any Person or agent
of such Person other than (a) a Disqualified Organization, (b) any other Person so designated by the Certificate Registrar who
is unable to provide an Opinion of Counsel (provided at the expense of such Person or the Person requesting the transfer) to the
effect that the transfer of an ownership interest in any Class R Certificate to such Person will not cause either Trust REMIC to
fail to qualify as a REMIC at any time that the Certificates are outstanding, (c) a Disqualified Non-U.S. Tax Person, (d) an entity
treated as a U.S. partnership if any of its partners, directly or indirectly (other than through a U.S. corporation) is (or is
permitted to be under the partnership agreement) a Disqualified Non-U.S. Tax Person or (e) a U.S. Tax Person with respect to which
income from a Class R Certificate is attributable to a foreign permanent establishment or fixed base, within the meaning of an
applicable income tax treaty, of the transferee or any other U.S. Tax Person.


 


6.           No
purpose of the acquisition of the Class R Certificates is to impede the assessment or collection of tax.


 


7.           The
Purchaser will not cause income from the Class R Certificate to be attributable to a foreign permanent establishment or fixed base,
within the meaning of an applicable income tax treaty, of the Purchaser or any other U.S. Tax Person.


 






    L-1-2 


     


    




 


8.           Check
the applicable paragraph:


 


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


 


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


 


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


 


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


 


For purposes of this
calculation, (i) the Purchaser is assumed to pay tax at the highest rate currently specified in Section 11(b) of the Code (but
the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in Section 11(b) of the Code
if the Purchaser has been subject to the alternative minimum tax under Section 55 of the Code in the preceding two years and will
compute its taxable income in the current taxable year using the alternative minimum tax rate) and (ii) present values are computed
using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d) of the Code for the month of the transfer
and the compounding period used by the Purchaser.


 


☐          The transfer
of the Class R Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,


 


(i)          the
Purchaser is an “eligible corporation”, as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to which
income from the Class R Certificate will only be taxed in the United States;


 


(ii)         at
the time of the transfer, and at the close of the Purchaser’s two fiscal years preceding the year of the transfer, the Purchaser
had gross assets for financial reporting purposes (excluding any obligation of a Person related to the Purchaser within the meaning
of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;


 


(iii)        the
Purchaser will transfer the Class R Certificate only to another “eligible corporation,” as defined in Treasury Regulations
Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of Treasury Regulations Sections 1.860E-1(c)(4)(i),
(ii) and (iii) and Treasury Regulations Section 1.860E-1(c)(5); and


 


(iv)        the
Purchaser determined the consideration paid to it to acquire the Class R Certificate based on reasonable market assumptions (including,
but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax
rates and other factors specific to the Purchaser) that it has determined in good faith.


 





☐          None of the
above.



 






    L-1-3 


     


    




  


9.           The
Purchaser historically has paid its debts as they have come due and intends to pay its debts as they come due in the future and
the Purchaser intends to pay taxes associated with holding the Class R Certificates as they become due.


 


10.         The
Purchaser understands that it may incur tax liabilities with respect to the Class R Certificate in excess of any cash flows generated
by such Certificate.


 


11.         The
Purchaser is aware that the Certificate Registrar will not register any transfer of a Class R Certificate by the Transferor unless
the Purchaser, or such Purchaser’s agent, delivers to the Certificate Registrar, among other things, an affidavit and agreement
in substantially the same form as this affidavit and agreement. The Purchaser expressly agrees that it will not consummate any
such transfer to any Person that does not provide an affidavit and agreement in substantially the same form as this affidavit and
agreement or as to which the Purchaser 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.


 


12.         The
Purchaser represents that it is not acquiring the Class R Certificate as a nominee, trustee or agent for any Person that is not
a Permitted Transferee and that for so long as it retains its interest in the Class R Certificate, it will endeavor to remain a
Permitted Transferee.


 


13.         The
Purchaser consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificate will only be owned, directly or indirectly, by a Permitted Transferee.


 


14.         The
Purchaser has reviewed the provisions of Section 5.03 of the Pooling and Servicing Agreement, a description of which provisions
is set forth in the Class R Certificates; and the Purchaser expressly agrees to be bound by and to comply with such provisions.


 


15.         The
Purchaser consents (a) to the designation of the Certificate Administrator as the attorney-in-fact and agent of the tax matters
person pursuant to Treasury Regulations Section 1.860F-4(d) and as the “partnership representative” within the meaning
of Code Section 6223 (to the extent such provision is applicable to the Trust REMICs) of each Trust REMIC pursuant to Section 4.04(a)
of the Pooling and Servicing Agreement and (b) to the Certificate Administrator making any elections allowed to avoid (i) the application
of Code Section 6221 to the Trust REMIC and (ii) payment by the Trust REMIC under Code Section 6225 of any tax, penalty, interest
or other amount imposed under the Code that would otherwise be imposed on the holders of the Class R Certificates.

Ladies and Gentlemen:


 


This letter is delivered
to you in connection with the transfer by [______] (the “Transferor”)
to [______] (the “Transferee”) of Class R Certificates
evidencing a [__]% Percentage Interest in such Class (the “Residual
Certificates”). The Certificates, including the Residual Certificates, were issued pursuant to the Pooling and

Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services, a Division of PNC Bank, National Association, as Master

N.A., as Certificate Administrator, and Wilmington Trust, National Association, as Trustee. All capitalized terms used but not
otherwise defined herein shall have the respective meanings set forth in the Pooling and Servicing Agreement. The Transferor hereby
certifies, represents and warrants to you, as Certificate Registrar, that:


 


(1)         No
purpose of the Transferor relating to the transfer of the Residual Certificates by the Transferor to the Transferee is or will
be to impede the assessment or collection of any tax.


 


(2)         The
Transferor understands that the Transferee has delivered to you a Transfer Affidavit and Agreement in the form attached to the
Pooling and Servicing Agreement as Exhibit L-1. The Transferor has no actual knowledge that the Transferee is not a Permitted Transferee
(as defined in such Transfer Affidavit and Agreement) and has no actual knowledge or reason to know that the Transferee’s
representations in clause (9) of such Transfer Affidavit and Agreement are false.


 


(3)         The
Transferor has at the time of this transfer conducted a reasonable investigation of the financial condition of the Transferee
as contemplated by Treasury regulation Section 1.860E-1(c)(4)(i) and, as a result of that investigation, the Transferor has determined
that the Transferee has historically paid its debts as they became due and has found no significant evidence to indicate that
the Transferee will not continue to pay its debts as they become due in

the future. The Transferor understands that the transfer
of the Residual Certificates may not be respected for United States income tax purposes (and the Transferor may continue to be
liable for United States income taxes associated therewith) unless the Transferor has conducted such an investigation.

3.       The
Purchaser acknowledges that the Transferred Certificate (and any Certificate issued on transfer or exchange thereof) has not been
registered or qualified under the Securities Act or the securities laws of any State or any other jurisdiction, and that the Transferred
Certificate cannot be reoffered, resold, pledged or otherwise transferred unless it is registered or qualified thereunder or unless
an exemption from such registration or qualification is available.


 


4.       The
Purchaser has reviewed the applicable Offering Circular dated October 20, 2017, relating to the Private Certificates (the “Offering
Circular”) and the agreements and other materials referred to therein and has had the opportunity to ask questions and
receive answers concerning the terms and conditions of the transactions contemplated by the Offering Circular.


 


5.       The
Purchaser hereby undertakes to be bound by the terms and conditions of the Pooling and Servicing Agreement in its capacity as
an owner of a Non-Book Entry Certificate or Certificates, as the case may be (each, a “Certificateholder”),
in all respects as if it were a signatory thereto. This undertaking is made for the benefit of the Trust, the Certificate Registrar
and all Certificateholders present and future.


 


6.       The
Purchaser will not sell or otherwise transfer any portion of the Transferred Certificate, except in compliance with Section 5.03
of the Pooling and Servicing Agreement.


 


7.       Check

☐       The
Purchaser is a “U.S. Tax Person” and it has attached hereto an Internal Revenue Service (“IRS”) Form W-9
(or successor form).


 


☐       The
Purchaser is not a “U.S. Tax Person” and under applicable law in effect on the date hereof, no taxes will be required
to be withheld by the Certificate Administrator (or its agent) with respect to Distributions to be made on the Transferred Certificate(s).
The Purchaser has attached hereto (i) a duly executed IRS Form W-8BEN or W-8 BEN-E, as applicable (or successor form), which identifies
such Purchaser as the beneficial owner of the Transferred Certificate(s) and states that such Purchaser is not a U.S. Person,
(ii) two duly executed copies of IRS Form W-8IMY (and all appropriate attachment) or (iii) two duly executed copies of IRS
Form W-8ECI (or successor form), which identify such Purchaser as the beneficial owner of the Transferred Certificate(s) and state
that interest and original issue discount on the Transferred Certificate(s) is, or is expected to be, effectively connected with
a U.S. trade or business. The Purchaser agrees to provide to the Certificate Administrator an updated IRS Form W-8BEN, IRS Form
W-8 BEN-E, IRS Form W-8IMY or IRS Form W-8ECI, as the case may be, any applicable successor IRS forms, or such other certifications
as the Certificate Administrator may reasonably request, on or before the date that any such IRS form or certification expires
or becomes obsolete, or promptly after the occurrence of any event requiring a change in the most recent IRS form of certification
furnished by it to the Certificate Administrator.

the purposes of this paragraph 7, “U.S. Tax Person” means a citizen or resident of the United States, a corporation,

the authority to control all substantial decisions of such trust (or, to the extent provided in applicable Treasury Regulations,
certain trusts in existence on August 20, 1996 that have elected to be treated as U.S. Tax Persons).

3.           The
term “securities” as used herein does not include (i) securities of issuers that are affiliated with the Purchaser,
(ii) securities that are part of an unsold allotment to or subscription by the Purchaser, if the Purchaser is a dealer, (iii) bank
deposit notes and certificates of deposit, (iv) loan participations, (v) repurchase agreements, (vi) securities owned
but subject to a repurchase agreement and (vii) currency, interest rate and commodity swaps. For purposes of determining the aggregate

    Annex-1-2


     


    




 


4.            For
purposes of determining the aggregate amount of securities owned and/or invested on a discretionary basis by the Purchaser, the
Purchaser used the cost of such securities to the Purchaser, unless the Purchaser reports its securities holdings in its financial
statements on the basis of their market value, and no current information with respect to the cost of those securities has been
published, in which case the securities were valued at market. Further, in determining such aggregate amount, the Purchaser may
have included securities owned by subsidiaries of the Purchaser, but only if such subsidiaries are consolidated with the Purchaser
in its financial statements prepared in accordance with generally accepted accounting principles and if the investments of such
subsidiaries are managed under the Purchaser’s direction. However, such securities were not included if the Purchaser is
a majority-owned, consolidated subsidiary of another enterprise and the Purchaser is not itself a reporting company under the
Securities Exchange Act of 1934, as amended.


 


5.            The
Purchaser acknowledges that it is familiar with Rule 144A and understands that the Seller and other parties related to the Transferred
Certificates are relying and will continue to rely on the statements made herein because one or more sales to the Purchaser may
be in reliance on Rule 144A.


 





	 	___    

    Yes     	___    

    No    	Will the Purchaser be purchasing the Transferred Certificate
    only for the Purchaser’s own account


 



 


6.            If
the answer to the foregoing question is “no”, then in each case where the Purchaser is purchasing for an account other
than its own, such account belongs to a third party that is itself a “qualified institutional buyer” within the meaning
of Rule 144A, and the “qualified institutional buyer” status of such third party has been established by the Purchaser
through one or more of the appropriate methods contemplated by Rule 144A.


 


7.           The
Purchaser will notify each of the parties to which this certification is made of any changes in the information and conclusions
herein. Until such notice is given, the Purchaser’s purchase of the Transferred Certificate will constitute a reaffirmation
of this certification as of the date of such purchase. In addition, if the Purchaser is a bank or savings and loan as provided
above, the Purchaser agrees that it will furnish to such parties any updated annual financial statements that become available
on or before the date of such purchase, promptly after they become available.

unless the Purchaser or any member of the Purchaser’s Family of Investment Companies, as the case may be, reports its securities

                                         with Rule 144A).



 


3.            The
term “Family of Investment Companies” as used herein means two or more registered investment companies (or series

5.           The
Purchaser is familiar with Rule 144A and understands that the parties to which this certification is being made are relying
and will continue to rely on the statements made herein because one or more sales to the Purchaser will be in reliance on Rule 144A.


 





	 	___    

    Yes     	___    

    No    	Will the Purchaser be purchasing the Transferred Certificate
    only for the Purchaser’s own account


 


 


6.           If
the answer to the foregoing question is “no”, then in each case where the Purchaser is purchasing for an account other
than its own, such account belongs to a third party that is itself a “qualified institutional buyer” within the meaning
of Rule 144A, and the “qualified institutional buyer” status of such third party has been established by the
Purchaser through one or more of the appropriate methods contemplated by Rule 144A.


 


7.           The
undersigned will notify the parties to which this certification is made of any changes in the information and conclusions herein.
Until such notice, the Purchaser’s purchase of the Transferred Certificate will constitute a reaffirmation of this certification

Mortgage Pass-Through Certificates, Series 2017-C4



 


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 Pooling and Servicing Agreement, dated as of October 1, 2017 (the “Pooling
and Servicing Agreement”), between Citigroup Commercial Mortgage Securities Inc., as Depositor, Midland Loan Services,
a Division of PNC Bank, National Association, as Master Servicer and Special Servicer, Park Bridge Lender Services LLC, as Operating
Advisor and Asset Representations Reviewer, Citibank, N.A., as Certificate Administrator, and Wilmington Trust, National Association,
as Trustee. All capitalized terms used but not otherwise defined herein shall have the respective meanings set forth in the Pooling
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 (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


 






    CC-2-1


     


    

 


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 CC-1 to the Pooling and Servicing Agreement, and (B) each of Midland Loan Services, a Division of PNC Bank, National
Association and the Depositor has received a certificate from the prospective transferee substantially in the form attached as
Exhibit CC-2 to the Pooling 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 3.12 of the Pooling 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
in the Excess Servicing Fee Right or any other similar security from any Person in any manner, (c) otherwise approached or negotiated
with respect to the Excess Servicing Fee Right, any interest in the Excess Servicing Fee Right or any other similar security with
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 (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 Pooling and Servicing Agreement and the Trust Fund created pursuant thereto, (d) the nature, performance and servicing
of the Mortgage Loans, and (e) all related matters that it has requested.


 


6.          The
Transferee is (a) a “qualified institutional buyer” within the meaning of Rule 144A under the Securities Act or (b)
an “accredited investor” as defined in any of paragraphs (1),


 






    CC-2-2


     


    

 


(2), (3) and (7) of Rule 501(a) under the Securities
Act or an entity in which all of the equity owners come within such paragraphs. 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 Pooling 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 such information, and to cause its officers, directors, partners, employees,
agents or representatives (collectively, “Representatives”) not to disclose such information, in any manner
whatsoever, in whole or in part, to any other Person other than the Transferee’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 Person or has become generally available to the public other than as a
result of disclosure by such Person; provided, however, that the Transferee or any of its Representatives 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 other 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 other Person’s 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 Pooling and Servicing
Agreement except as set forth in Section 3.12 of the Pooling and Servicing Agreement, and that the Excess Servicing Fee Rate may
be reduced to the extent provided in the Pooling and Servicing Agreement.

[Include the following, with appropriate modification, if there is pari passu or AB debt: as evidenced by that certain Promissory
Note [A-[_]][A] in the amount of $____________, which Promissory Note [A-[_]][A] is owned by the Trust, and Promissory Note [___]
in the amount of $_____________, which Promissory Note [___] is owned by ________________.]



 


Capitalized terms used
but not defined herein have the meanings assigned to such terms in the Pooling and Servicing Agreement.


 


THE STATEMENTS SET
FORTH BELOW ARE MADE (A) TO THE BEST KNOWLEDGE OF THE UNDERSIGNED BASED UPON DUE DILIGENCE CONSISTENT WITH THE SERVICING STANDARD
SPECIFIED IN THE POOLING


 






    DD-1


     


    

 


AND SERVICING AGREEMENT (THE “SERVICING STANDARD”), AND (B) WITHOUT INTENDING TO WARRANT
THE ACCURACY THEREOF OR UNDERTAKE ANY DUTY OR STANDARD OF CARE GREATER THAN THE DUTIES OF SERVICER UNDER THE POOLING AND SERVICING
AGREEMENT AND THE SERVICING STANDARD.


 


We hereby notify you
and confirm that each of the following is true, subject to those exceptions, if any, set forth on Exhibit A hereto, which exceptions
the Master Servicer has determined, consistent with the Servicing Standard, will have no material adverse effect on the Subject
Mortgage Loan or the defeasance transaction:


 


1.          The
Mortgagor has consummated a defeasance of the Subject Mortgage Loan of the type checked below:**


 


____ a full defeasance
of the entire outstanding principal balance ($____________) of the Subject Mortgage Loan; or


 


____ a partial
defeasance of a portion ($____________) of the Subject Mortgage Loan that represents ___% of the entire principal balance of the
Subject Mortgage Loan ($____________).


 


2.          The
defeasance was consummated on ____________, 20__.


 


3.          The
defeasance was completed in all material respects in accordance with the conditions for defeasance specified in the Loan Documents
and in accordance with the Servicing Standard.


 


[Include the following if
there is pari passu or AB debt:


 


4.          In
accordance with the Loan Documents, the defeasance occurred such that:


 


____ Promissory
Notes [A-[__]][A] and [___] were defeased simultaneously in their entirety; or


 


____ Promissory
Note [___] was paid off in full.]


 


5.          To
the knowledge of the Master Servicer any other debt related to the Subject Mortgage Loan (including mezzanine debt, senior secured
debt, pari passu debt or subordinate secured debt was either paid off in full or defeased. Such debt consists of the following:
[Describe debt and holder of the debt and if it was paid off or defeased].


 


6.          The
defeasance collateral consists only of one or more of the following: (i) direct debt obligations of the U.S. Treasury, (ii) direct
debt obligations of the Federal National Mortgage Association, (iii) direct debt obligations of the Federal Home Loan Mortgage
Corporation, (iv) interest-only direct debt obligations of the Resolution Funding Corporation, (v) consolidated debt obligations
of the Federal Home Loan Bank or (vi) securities covered by the Federal Deposit Insurance Corporation’s (the “FDIC”)
Temporary Liquidity Guarantee Program


 






    DD-2


     


    

 


(“TLGP”). Based upon a written report from an independent certified accountant,
such defeasance collateral consists of securities that (i) if they include a principal obligation, the principal due at maturity
cannot vary or change, (ii) provide for interest at a fixed rate and (iii) are not callable prior to their respective maturity
dates. In addition, if the defeasance collateral contains any TLGP securities, then:


 


		●	Such securities are eligible under TLGP;



 


		●	The master servicer (and the trustee, if it serves as the back-up advancing agent for the transaction)
has waived its right to (i) collect interest on advances made on behalf of the borrower holding TLGP securities, and (ii) collect
for expenses incurred in making demand on the FDIC;



 


		●	If the TLGP debt is to be used to satisfy a balloon payment, a reserve conforming to the criteria
for eligible accounts was funded with a minimum of 90 days interest on the defeasance collateral to cover potential delays in receipt
of the balloon payment;



 


		●	The TLGP securities mature before June 30, 2012; and



 


		●	The master servicer’s error and omissions insurance policy covers losses to the CMBS trust
caused by the master servicer’s failure to make timely demand on the FDIC’s guarantee.



 


7.            After
the defeasance, the defeasance collateral will be owned by an entity (the “Defeasance Obligor”) that: (i) is
the original Mortgagor, (ii) is a Single-Purpose Entity (as described in S&P’s criteria), (iii) is subject to restrictions
in its organizational documents substantially similar to those contained in the organizational documents of the original Mortgagor
with respect to bankruptcy remoteness and single purpose, (iv) has been designated as the Defeasance Obligor by the originator
of the Subject Mortgage Loan pursuant to the terms of the Loan Documents, or (v) has previously received confirmation from Standard
& Poor’s that the organizational documents of such Defeasance Obligor conform with applicable Standard & Poor’s
criteria. The Defeasance Obligor owns no assets other than defeasance collateral and (only in the case of the original Mortgagor)
real property securing one or more Mortgage Loans included in the pool under the Pooling and Servicing Agreement (the “Pool”).


 


8.            If
such Defeasance Obligor (together with its affiliates) holds more than one defeased loan, it does not (together with its affiliates)
hold defeased loans aggregating more than $35 Million or more than five percent (5%) of the aggregate certificate balance of the
Certificates, as of the date of the most recent Certificate Administrator’s Distribution Date Statement received by the Master
Servicer (the “Current Report”), except to the extent the Defeasance Obligor is of the type specified in paragraph
7(v) above or the original Loan Documents do not limit the amount of defeased loans that it may hold.


 


9.            The
defeasance documents require that the defeasance collateral be credited to an eligible account (as defined in S&P’s criteria)
that must be maintained as a securities account by a securities intermediary that is at all times an Eligible Institution (as


 






    DD-3


     


    

 


defined
in S&P’s criteria). The securities intermediary may reinvest proceeds of the defeasance collateral only in Permitted
Investments (as defined in the Pooling and Servicing Agreement or as defined in the documents evidencing defeasance).


 


10.          The
securities intermediary is obligated to pay from the proceeds of the defeasance collateral, directly to the Master Servicer’s
collection account, all scheduled payments on the Subject Mortgage Loan or, in a partial defeasance, the portion of such scheduled
payments attributed to the allocated loan amount for the real property defeased including any defeasance premiums set forth in
the loan documents (the “Scheduled Payments”).


 


11.          The
Master Servicer received written confirmation from an independent certified public accountant stating that (i) revenues from the
defeasance collateral (without taking into account any earnings on reinvestment of such revenues) will be sufficient to timely
pay each of the Monthly Payments including the payment in full of the Subject Mortgage Loan (or the allocated portion thereof in
connection with a partial defeasance) on its Maturity Date (or, in the case of an ARD Loan, on its Anticipated Repayment Date),
(ii) except as otherwise disclosed in the written report from an independent certified public accountant, [and disclosed below,]
the revenues received in any month from the defeasance collateral will be applied to make Monthly Payments within four (4) months
after the date of receipt, (iii) the defeasance collateral is not callable prior to their respective maturity dates, and (iv) interest
income from the defeasance collateral to the Defeasance Obligor in any tax year will not exceed such Defeasance Obligor’s
interest expense for the Subject Mortgage Loan (or the allocated portion thereof in a partial defeasance) for such year, other
than in the year in which the Maturity Date or Anticipated Repayment Date will occur, when interest income will exceed interest
expense.


 


12.          The
Master Servicer received opinions of counsel that, subject to customary qualifications, (i) the defeasance will not cause either
Trust REMIC to fail to qualify as a REMIC for purpose of the Code, (ii) the agreements executed by the Mortgagor and the Defeasance
Obligor in connection with the defeasance are enforceable against them in accordance with their terms, [and] (iii) the Trustee
will have a perfected, first priority security interest in the defeasance collateral.


 


13.          The
agreements executed in connection with the defeasance (i) prohibit subordinate liens against the defeasance collateral, (ii) provide
for payment from sources other than the defeasance collateral of all fees and expenses of the securities intermediary for administering
the defeasance and the securities account and all fees and expenses of maintaining the existence of the Defeasance Obligor, (iii)
permit release of surplus defeasance collateral and earnings on reinvestment to the Defeasance Obligor only after the Subject Mortgage
Loan has been paid in full, (iv) include representations and/or covenants of the Mortgagor and/or securities intermediary substantially
as set forth on Exhibit B hereto, (v) provide for survival of such representations; and (vi) do not permit waiver of such representations
and covenants.


 


14.          At
the time of the defeasance of the Subject Mortgage Loan, the Subject Mortgage Loan is (x) not one of the ten largest Mortgage Loans
by Stated Principal Balance, (y) a Mortgage Loan with a Stated Principal Balance equal to or less than $35,000,000 and (z) a Mortgage
Loan that represents less than 5% of the Stated Principal Balance of all Mortgage Loans.


 



    DD-4


     


    

 


15.          Copies
of all material agreements, instruments, organizational documents, opinions of counsel, accountant’s report and other items
delivered in connection with the defeasance will be provided to you upon request.


 


16.          The

General:


 


1.          [The
defeasance agreements] create a valid and continuing security interest (as defined in the applicable UCC) in the [Collateral, Securities
Account and Deposit Account] in favor of the [Secured Party], which security interest is prior to all other [Liens], and is enforceable
as such as against creditors of and purchasers from [Debtor].


 


Note that “Collateral”
means securities, permitted investments and other assets credited to securities accounts.


 


1.          The
[Deposit Account] constitutes a “deposit account” within the meaning of the applicable UCC.


 


2.          All
of the [Collateral] has been and will have been credited to a [Securities Account]. The securities intermediary for the [Securities
Account] has agreed to treat all assets credited to the [Securities Account] as “financial assets” within the meaning
of the UCC.


 


Creation:


 


1.          The
Defeasance Account Agreement provides that the Pledgee shall have “control” (as defined in the applicable UCC).


 


2.          [Debtor]
has received all consents and approvals required by the terms of the [Collateral] to the transfer to the [Secured Party] of its
interest and rights in the [Collateral] hereunder.


 


Perfection:


 


1.          [Debtor]
has caused or will have caused, within ten (10) days, the filing of all appropriate financing statements in the proper filing office
in the appropriate jurisdictions under applicable law in order to perfect the security interest granted in the [Collateral, Securities
Account and Deposit Account] to the [Secured Party] hereunder.


 


2.          [Debtor]
has delivered to[Secured Party] a fully executed agreement pursuant to which the securities intermediary or the account bank has
agreed to comply with all instructions originated by the [Secured Party] relating to the [Securities Account] or directing disposition
of the funds in the [Deposit Account] without further consent by the [Debtor].


 


3.          [Debtor]
has taken all steps necessary to cause the securities intermediary to identify in its records the [Secured Party] as the person
having a security entitlement against the securities intermediary in the [Securities Account].


 


4.          To
the extent a Deposit Account exists, [Debtor] has taken all steps necessary to cause [Secured Party] to become the account holder
of the [Deposit Account].


 



    DD-7


     


    

 


Priority:


 


1.       Other
than the security interest granted to the [Secured Party] pursuant to this Agreement, [Debtor] has not pledged, assigned, sold,
granted a security interest in, or otherwise conveyed any of the [Collateral, Securities Account and Deposit Account]. [Debtor]
has not authorized the filing of and is not aware of any financing statements against [Debtor] that include a description of collateral
covering the [Collateral, Securities Account and Deposit Account] other than any financing statement relating to the security interest
granted to the [Secured Party] hereunder or that has been terminated. Debtor is not aware of any judgment or tax lien filings against
[Debtor].


 


2.       The
[Securities Account and Deposit Account] are not in the name of any person other than the [Debtor] or the [Secured Party]. The
[Debtor] has not consented to the securities intermediary of any [Securities Account] or the account bank of any [Deposit Account]
to comply with entitlement orders or instructions of any person other than the [Secured Party].

the undersigned, as asset representations reviewer (the “Asset Representations Reviewer”), has performed an
Asset Review on each Delinquent Loan identified by the Certificate Administrator, and is hereby issuing the following Asset Review
Report.


 


	 	1.	We have performed an Asset Review on each Delinquent Loan identified by the Certificate Administrator and our conclusion is that there is [no evidence of a failed Test][evidence of [•] failed Tests as specifically detailed on the scorecard attached hereto as Exhibit A] with respect to the Delinquent Loans. 


 


	 	2.	A conclusion by the Asset Representations Reviewer of a passed Test or a failed Test shall not constitute a determination by the Asset Representations Reviewer of (i) the existence or nonexistence of a Material Defect, or (ii) whether the Trust should enforce any rights it may have against the applicable Mortgage Loan Seller. In addition, the Tests may not be sufficient to determine every instance of noncompliance.


 


	 	
        3.
	
        The Asset Representations Reviewer,
other than forwarding this report to the persons listed above, will not be required to take or participate in any other or further
action with respect to the aforementioned Asset Review Report.

ASSET REVIEW PROCEDURES


 


Subject to the Pooling and Servicing Agreement,
this Exhibit sets forth Asset Representations Reviewer’s review procedures for Asset Review of each Delinquent Loan. Capitalized
terms used herein and not defined herein shall have the meanings ascribed to them in the Pooling and Servicing Agreement. In the
event of any conflict between this Exhibit JJ and the terms of the Pooling and Servicing Agreement, the Pooling and Servicing Agreement
shall control and govern the Asset Representations Reviewer’s responsibilities and duties with respect to Asset Reviews.


 


Call for Review and Collection and Inventory
of Review Materials


 


		Step 1	Asset Representations Reviewer (“ARR”)
receives the following items before beginning its review:



 


		■	Notice of Asset Review Trigger (with attachments)



 


		■	Notice of Asset Review Vote Election



 


		■	Asset Review Notice



 


		■	List of all Delinquent Loans



 


		■	Review Materials for each Delinquent Loan via Secure Data Room access, including, among other documents, the Diligence File



 


		■	Any Unsolicited Information (if applicable)



 


		Step 2	For each Delinquent Loan, ARR inventories all Review Materials
to which ARR is provided access in the Secure Data Room to determine what, if any, Review Materials for such Delinquent Loan are
missing, using the list of documents in the definition of “Mortgage File” of this Agreement, any comparable lists
included in the related Loan Purchase Agreement, and any closing checklist from the origination of such Delinquent Loan, to guide
its review and determination



 






    JJ-1


     


    

 


		Step 3	If ARR determines that the Review Material made available
or delivered to it in the Secure Data Room with respect to any Delinquent Loan is missing any documents required to complete an
Asset Review of such Delinquent Loan, ARR shall prepare list of such missing documents and notify the Master Servicer (with respect
to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans) of such missing documents.
If any missing documents are not provided by the Master Servicer or the Special Servicer, as applicable, the ARR shall request
such documents from the related Mortgage Loan Seller.



 


Analysis and
Testing of Representations and Warranties


 


		Step 4	For each Delinquent Loan for which ARR has received all
Review Materials required to complete an Asset Review of such Delinquent Loan, ARR tests such Delinquent Loan for compliance with
each representation and warranty made by the related Mortgage Loan Seller with respect to such Delinquent Loan as follows:



 


		■	ARR reviews each representation and warranty and each item included in the Review Materials applicable or related to such representation
or warranty to determine whether there is any evidence that such representation or warranty was not true when made by the related
Mortgage Loan Seller



 


		■	For each representation and warranty, ARR lists



 


		●	all items from the Review Materials reviewed or used in its testing of such representation and warranty



 


		●	whether ARR has determined that there is any evidence that such representation or warranty was not true when made by the related
Mortgage Loan Seller, and



 


		○	if so, stating the aspect of the applicable representation or warranty that does not appear to have been true when made by
the related Mortgage Loan Seller and ARR’s basis for its conclusion



 


		○	completing the Asset Review Report by setting forth, for each Delinquent Loan, the information contemplated herein with respect
to each representation and warranty



 


ARR will not attempt (and has no obligation) to determine
the materiality of any potential breach of a representation or warranty that it discovers evidence of during its review as contemplated
herein
