This RETIREMENT AND CONSULTING AGREEMENT (together with any Exhibits hereto, this “Agreement”) is entered into by and between DSW Inc., an Ohio corporation (the “Company”) and Michael R. MacDonald (“Executive” and, together with the Company, the “Parties”) dated as of November 20, 2015, and confirms the agreement that has been reached with Executive in connection with his departure from the Company.
RECITALS
WHEREAS, Executive is currently employed by the Company as its President and Chief Executive Officer pursuant to a Standard Executive Employment Agreement dated as of March 25, 2009 (the “Employment Agreement”); and
WHEREAS, Executive will resign from his employment with the Company on the date specified herein, and upon ceasing to serve as an employee of the Company, Executive will serve as an independent contractor for the Company providing consulting services to and for the benefit of the Company as hereinafter described during the Consulting Term specified below, all according to the terms provided herein.
NOW, THEREFORE, in consideration of the premises and the mutual covenants set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties, intending to be legally bound, hereby agree as follows:
1.Resignation of Employment.

(a)Upon execution of this Agreement, Executive agrees to and hereby does resign from employment with the Company, effective as of December 31, 2015 (the “Retirement Date”), at which time Executive’s employment with the Company shall cease.  Executive shall resign from his position as President and Chief Executive Officer of the Company, as an employee of any affiliate or subsidiary of the Company and as a member of the Board of Directors of the Company (the “Board”) and the board of directors of any subsidiaries of the Company on which he might serve, in each case, effective as of the Retirement Date.  Following the Retirement Date, Executive shall provide consulting services to the Company pursuant to Section 3 below.  Upon request of the Company, Executive agrees to execute such documents and take such action as may be necessary or desirable to effectuate the foregoing; however, should Executive not execute such documents, he shall nevertheless be deemed to have resigned on the Retirement Date from all such employment positions and his position as a director of the Company.

(b)From the date hereof through the Retirement Date, Executive shall continue in the employ of the Company pursuant to the terms of the Employment Agreement, provided that during such period (i) Executive shall perform such services as may be reasonably requested by the Chairman of the Board, including without limitation those intended to ensure a smooth transition of responsibility to the individual succeeding Executive as Chief Executive Officer of the Company (the “Successor CEO”) and support to the Successor CEO and other senior Company management (which Executive acknowledges may require travel to Columbus, Ohio, New York City and Canada among other places), and (ii) Executive will not terminate or purport to terminate his employment for “Good Reason” within the meaning of the Employment Agreement.

(c)Other than as set forth in this Agreement, following the Retirement Date, Executive shall not receive any base salary, annual bonus, long term incentive award, welfare, retirement, perquisite, fringe benefit, or other benefit plan coverage or coverage under any other practice, policy or program as may be in effect from time to time, applying to senior officers or other employees of the Company, or any severance payment or benefit to be received under the Employment Agreement or any severance benefit plans, practices, policies or programs, or any paid time off or expense reimbursement (other than any federal COBRA or similar state rights, which Executive may have, at his sole expense subject to Section 2(a) below); however, subject to the provisions of this Agreement, Executive shall receive all benefits and conversion rights, at the applicable time, earned, due or applicable under the terms of Company benefit or retirement plans, including payment of all earned but unpaid base salary through the Retirement Date and payment of any accrued and unused paid time off.

2.Certain Payments.

(a)Provided that Executive before the Retirement Date has not terminated his employment with the Company or been terminated by the Company for “Cause” within the meaning of the Employment Agreement, then subject to Executive executing the Release of Claims in the form attached hereto as Exhibit A (the "Release") on or within twenty-one (21) days following the Retirement Date and not revoking it before it has become irrevocable in accordance with its terms, and subject further to Executive’s compliance with the remaining provisions of this Agreement, Executive shall be eligible to receive the 

following compensation and benefits, subject to all tax and other withholdings and deductions required or permitted by applicable law or Company policies:

(i)$530,000 payable in twelve (12) equal monthly installments, commencing within five 5 business days following the Effective Date, and an additional $607,500 payable in seven (7) equal monthly installments commencing as soon as practicable six (6) months after the Retirement Date (collectively, the “Monthly Payments”); and

(ii)the compensation and benefits described in Exhibit B hereto.

The first twelve (12) Monthly Payments shall be subject to reporting on an IRS W-2 tax form.
(b)The Company shall reimburse Executive for all reasonable out-of-pocket expenses incurred by Executive during the Consulting Term in conjunction with providing the Services.  Executive shall bill the Company monthly for all such expenses (including providing reasonably required documentation of such expenses), which invoices the Company shall pay in accordance with the Company’s expense reimbursement policy. 

3.Consulting Term and Services.

(a)Provided that Executive before the Retirement Date has not terminated his employment with the Company or been terminated by the Company for “Cause” within the meaning of the Employment Agreement, then subject to Executive executing the Release on or within twenty-one (21) days following the Retirement Date and not revoking it before it has become irrevocable in accordance with its terms, the Company hereby retains Executive, from the “Effective Date” of the Release (within the meaning of Section 3(c) thereof) through January 28, 2017 (the "Consulting Term"), to provide consulting services intended to ensure a smooth transition of responsibility to the Successor CEO and support to such individual and other senior Company management (the “Services”), which Executive acknowledges may require travel to Columbus, Ohio, New York City and Canada among other places.  During the Consulting Term, Executive shall report directly to the Successor CEO, who shall determine and communicate to Executive the nature of the Services required of Executive from time to time.  During the Consulting Term, Executive shall make himself available to perform the Services at such times during business hours as may be reasonably requested by the Successor CEO, but not in excess of twenty (20) hours per month.  The Parties acknowledge that Executive may engage in other business activities during the Consulting Term, provided that such activities do not violate the restrictive covenants applicable to Executive under Section 4.00 of the Employment Agreement or otherwise prevent Executive from performing the Services.

(b)The Company will provide Executive such information about the business activities of the Company and its affiliates as Executive may reasonably require in order to carry out the Services.

(c)All Services will be performed by Executive with a level of skill and care generally exercised by others performing the same or similar services.  Executive shall, subject to Section 3(a) above, devote such time and effort as are reasonably necessary to perform the Services.  In performing the Services, Executive will comply fully with all applicable laws and all applicable policies of the Company.  Executive will not be required to maintain regular office hours.

4.Independent Contractor Status.

(a)Executive shall at all times during the Consulting Term be an independent contractor with respect to the Company and there shall not be implied any relationship of employer-employee, partnership, joint venture, principal and agent or the like by the agreements contained herein.  During the Consulting Term, Executive shall not be entitled to participate in any employee benefit plans or other benefits or conditions of employment available to the employees of the Company or its affiliates (other than any federal COBRA or similar state rights, which Executive may have).

(b)During the Consulting Term, Executive shall not have any authority to act as an agent of the Company and its affiliates, except on authority expressly and specifically so delegated in a prior writing from the Successor CEO, and he shall not represent to the contrary to any person.  Under no circumstances shall Executive have or claim to have power of decision hereunder in any activity on behalf of the Company, nor shall Executive have the power or authority hereunder to obligate, bind or commit the Company in any respect.  Executive shall not (i) direct the work of any employee of the Company, (ii) make any management decisions on behalf of the Company or (iii) undertake to commit the Company to any course of action in relation to third persons.  Although the Company may specify the results to be achieved by Executive and may control and direct him in that regard, the Company shall not exercise or have the power to exercise such level of control over Executive as would indicate or establish that a relationship of employer and employee exists between the Company, on the one hand, and 

Executive, on the other hand.  Subject to the terms of this Agreement, Executive shall have full and complete control over the manner and method of rendering the Services.

(c)Executive shall be issued an IRS 1099 tax form by the Company reflecting the applicable amount of any taxable payments received by Executive in respect of the Services (including without limitation the portion of the Monthly Payments paid in respect of the thirteenth (13th) month following the Retirement Date (the “Consulting Cash Payment”)) for the applicable calendar year.  To the extent consistent with applicable law, the Company shall not withhold or deduct any amount or amounts in respect of income taxes or other employment taxes of any other nature on behalf of Executive from any taxable payments received by Executive in respect of the Services (including without limitation the Consulting Cash Payment).  Executive shall be solely responsible for the payment of any federal, state, local or other income and/or self-employment taxes in respect of the amounts payable to Executive by reason of his provision of the Services (including without limitation the Consulting Cash Payment) and shall hold the Company and its affiliates and their officers, directors and employees harmless from any liability arising from Executive’s failure to comply with the foregoing provisions of this sentence.

5.Indemnity.  The Company shall jointly and severally defend, indemnify and hold harmless Executive from and against any and all suits, claims, causes of action, damages, losses, liabilities, obligations, costs or expenses (including reasonable attorneys’ fees) incurred by or asserted against Executive arising out of, relating to or otherwise resulting in whole or in part from any of the Services, excluding those arising out of the willful acts or omissions by, or gross negligence of, Executive and excluding Executive's failure to pay taxes consistent with Section 4 above.

6.Cooperation.  Executive agrees that, upon reasonable notice and without the necessity of the Company’s obtaining a subpoena or court order, Executive shall provide reasonable cooperation in connection with any suit, action or proceeding (or any appeal from any suit, action or proceeding), and any investigation and/or defense of any claims asserted against the Company or any of its affiliates, that relates to events occurring during the Consulting Term as to which Executive may have relevant information (including but not limited to furnishing relevant information and materials to the Company or its designee and/or providing testimony at depositions and at trial), provided that the Company agrees to reimburse Executive for out-of-pocket expenses reasonably incurred in connection with any such cooperation, and provided that any such cooperation shall be scheduled to the extent reasonably practicable so as not to unreasonably interfere with Executive’s business or personal affairs.

7.Governing Law.  This Agreement shall be governed by and construed in accordance with the laws of the State of Ohio applicable to agreements made and to be performed in that state, without reference to its principles of conflicts of law.  The Parties shall submit any and all claims controversies, disputes, or conflicts of any type and of any manner among the Parties, including without limitation any such disputes regarding or with respect to this Agreement or the Release, pursuant to Section 9.00 of the Employment Agreement (subject to Section 4.10 of the Employment Agreement).

8.Section 409A.  The intent of the Parties is that payments and benefits under this Agreement comply with Section 409A of the Code (“Section 409A”) to the extent subject thereto, and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted and administered to be in compliance therewith.  Notwithstanding anything herein to the contrary: (i) if at the time of Executive’s termination of employment with the Company, Executive is a “specified employee” as defined in Section 409A and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided to Executive) until the date that is six (6) months following Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A); (ii) if any other payments of money or other benefits due to Executive hereunder could cause the application of an accelerated or additional tax under Section 409A, such payments or other benefits shall be deferred if deferral will make such payment or other benefits compliant under Section 409A, or otherwise such payment or other benefits shall be restructured, to the extent possible, in a manner, determined by the Board that does not cause such an accelerated or additional tax; (iii) to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A, Executive shall not be considered to have terminated employment with the Company for purposes of this Agreement and no payment shall be due to Executive under this Agreement until Executive would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A; and (iv) each amount to be paid or benefit to be provided to Executive pursuant to this Agreement, which constitute deferred compensation subject to Section 409A, shall be construed as a separate identified payment for purposes of Section 409A.  To the extent required to avoid an accelerated or additional tax under Section 409A, amounts reimbursable to Executive under this Agreement shall be paid to Executive on or before the last day of the year following the year in which the expense was incurred and the amount of expenses eligible for reimbursement (and in-kind benefits provided to Executive) during any one year may not affect amounts reimbursable or provided in any subsequent year.

9.Legally Authorized.  Each Party represents that it is competent to enter into this Agreement and has the requisite authority to enter into this Agreement.  No Party has agreed or promised to do or omit to do any act or thing not herein set forth, and the Parties further understand that a purpose of this Agreement is to compromise and terminate all Claims (as defined in Exhibit A hereto) of whatever nature, known or unknown, held by Executive.

10.Joint Preparation.  This Agreement shall be deemed to have been prepared jointly by the Parties.  Any uncertainty or ambiguity existing herein shall not be interpreted against any Party.

11.No Admission.  Executive understands that this Agreement shall not in any way be construed as an admission by the Company or any other Company Releasee (within the meaning of Exhibit A hereto) of any wrongdoing whatsoever against Executive.  The Company specifically disclaims any liability for any wrongdoing against Executive and denies any such wrongdoing, on the part of itself, or its employees, its agents, or any of the other Company Releasees.

12.Notice.  All notices under this Agreement, including the service of a subpoena or other court process and communications between the Parties, shall be in writing and delivered in person or sent by overnight courier, postage prepaid, or by facsimile transmission, to the addresses set forth below, or to such other address(es) of which notice is given in accordance with this Section 13 and shall be deemed given in the event of hand delivery upon receipt or, if by overnight courier or facsimile, upon being sent:

(a)This Agreement and (to the extent applicable) the Employment Agreement set forth the entire agreement of the Parties in respect of Executive’s termination of employment and the consulting services to be provided by Executive to the Company following the Retirement Date and, except as explicitly stated herein, supersedes all prior agreements, promises,

In the event any term or condition of this Agreement is determined to be invalid, prohibited or unenforceable by a court or other body of competent jurisdiction, this Agreement shall be construed as if such invalid, prohibited or unenforceable term or condition has been more narrowly drawn so as not to be invalid, prohibited or unenforceable.  Notwithstanding the foregoing sentence, in the event that any term or condition contained in this Agreement should be determined to be invalid, prohibited or unenforceable, the validity, legality and enforceability of the remaining terms or conditions contained in this Agreement shall not in any way be affected or impaired thereby.

(d)No waiver of any one or more of the terms, conditions or obligations of this Agreement, and no partial waiver thereof, shall be construed as a waiver of any succeeding breach of any of such terms, conditions or obligations or of any of the other terms, conditions or obligations of this Agreement.  No failure or delay by either Party at any time to enforce one or more of the terms, conditions or obligations of this Agreement shall constitute a waiver of such terms, conditions or obligations or shall preclude such Party from requiring performance by the other Party at any time.  

(e)The headings of this Agreement are inserted for convenience only and neither constitute a part of this Agreement nor affect in any way the meaning or interpretation of this Agreement.  When a reference in this Agreement is made to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated.

(f)This Agreement may be executed in one or more counterparts, including emailed or telecopied facsimiles, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
EXECUTIVE REPRESENTS AND AGREES THAT EXECUTIVE HAS BEEN AFFORDED A REASONABLE AMOUNT OF TIME TO REVIEW THIS AGREEMENT, TO UNDERSTAND ITS CONTENTS, TO VOLUNTARILY ENTER INTO THIS AGREEMENT AND TO BE BOUND BY ITS SPECIFIC, STATED OBLIGATIONS AND IS SPECIFICALLY ADVISED TO CONSULT WITH AN ATTORNEY PRIOR TO EXECUTING THIS AGREEMENT.

Pooling and Servicing
Agreement, dated as of November 1, 2015, among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Master Servicer, Midland Loan Services, a Division of PNC Bank, National Association, as Special
Servicer, Pentalpha Surveillance LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Certificate Administrator,
and Wilmington Trust, National Association, as Trustee.

 

PRELIMINARY STATEMENT:

(Terms used but not defined in this Preliminary

Statement shall have the meanings

specified in Article I hereof)

 

The Depositor intends
to sell pass-through certificates to be issued hereunder in multiple classes which in the aggregate will evidence the entire beneficial
ownership interest in the Trust Fund consisting primarily of the Mortgage Loans. As provided herein, the Certificate Administrator
will elect that two segregated portions of the Trust Fund be treated for federal income tax purposes as two separate REMICs (each,
a “Trust REMIC” or, in the alternative, the “Upper-Tier REMIC” and the “Lower-Tier
REMIC”, respectively). The Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class A-S, Class B, Class
C, Class D, Class X-D, Class E, Class F, Class G, Class NR, Class X-A, Class X-B, Class X-F, Class X-G and Class X-NR
Certificates will represent “regular interests” in the Upper-Tier REMIC and the Upper-Tier Residual Interest will represent
the sole class of “residual interests” in the Upper-Tier REMIC.

 

There are also (i) 13
classes of uncertificated Lower-Tier Regular Interests issued under this Agreement (the Class LA-1, Class LA-2, Class LA-3,
Class LA-4, Class LA-SB, Class LA-S, Class LB, Class LC, Class LD, Class LE, Class LF, Class LG and Class LNR
Interests), each of which will constitute a class of “regular interests” in the Lower-Tier REMIC, and (ii) the Lower-Tier
Residual Interest, which will represent the sole class of “residual interests” in the Lower-Tier REMIC.

 

The Lower-Tier Regular
Interests will be held by the Trustee as assets of the Upper-Tier REMIC. The Class R Certificates will represent both the Lower-Tier
Residual Interest and the Upper-Tier Residual Interest.

 

UPPER-TIER REMIC

 

The following table sets
forth the Class designation, the approximate initial pass-through rate (the “Pass-Through Rate”), the aggregate
initial principal balance (the “Original Certificate Principal Balance”) or, in the case of the Class X-A,
Class X-B, Class X-D, Class X-F, Class X-G and Class X-NR Certificates, notional amount (the “Original Notional Amount”),
as applicable, and the initial ratings given each Class by the Rating Agencies (the “Original Ratings”) for
each Class of Certificates comprising or evidencing the interests in the Upper-Tier REMIC created hereunder:

                                         Date. The Class X-D Certificates will not have a Pass-Through Rate, but will be entitled
                                         to receive the sum of the interest distributable on the Class X-D Components. The Pass-Through
                                         Rate for the Class D Component of the Class X-D Certificates is fixed and, for each Distribution
                                         Date, will equal the Class X Strip Rate for the Class D Component for such Distribution

                                         and, for each Distribution Date, will equal the Class X Strip Rate for the Class E Component
                                         for such Distribution Date. The Class X-F Pass-Through Rate is variable and, for each
                                         Distribution Date, will equal the Class X Strip Rate for the Class F Component for such
                                         Distribution Date. The Class X-G Pass-Through Rate is variable and, for each Distribution
                                         Date, will equal the Class X Strip Rate for the Class G Component for such Distribution
                                         Date. The Class X-NR Pass-Through Rate is variable and, for each Distribution Date, will
                                         equal the Class X Strip Rate for the Class NR Component for such Distribution Date.

                                         Principal Balances; rather, each such Class of Certificates will accrue interest as provided
                                         herein on the related Notional Amount. The Class X-D Certificates will not have a Certificate
                                         Principal Balance and will receive interest that accrues on the Class D Component and
                                         Class E Component.

 

		(4)	The Class R
                                         Certificates do not have a Certificate Principal Balance or Notional Amount, do not bear

                                         Lower-Tier Regular Interest is also the “Corresponding Lower-Tier Regular Interest” with respect to the Corresponding Certificate and the Corresponding Component, each
                                         Corresponding Certificate is the Corresponding Certificate with respect to the Corresponding
                                         Component and each Corresponding Component is the Corresponding Component with respect
                                         to the Corresponding Certificates.

 

The Certificate Principal
Balance of any Class of Principal Balance Certificates outstanding at any time represents the maximum amount which holders thereof
are then entitled to receive as distributions allocable to principal from the cash flow on the Mortgage Loans and the other assets
in the Trust Fund; provided, however, that in the event that amounts previously allocated as Realized Losses to a
Class of Principal Balance Certificates in reduction of the Certificate Principal Balance thereof are recovered subsequent to the
reduction of the Certificate Principal Balance of such Class to zero, such Class may receive distributions in respect of such recoveries
in accordance with the priorities set forth in Section 4.01 of this Agreement. As of the Cut-Off Date, the Mortgage Loans
have an aggregate Stated Principal Balance equal to approximately $939,639,786.

Amount is
required to be calculated, an amount (subject to the operation of the final paragraph of Section 3.10(a)) equal to the excess,
if any, of (a) the Stated Principal Balance of such Mortgage Loan (or Serviced Whole Loan) as of the last day of the related
Collection Period over (b) the excess of (i) the sum of (A) 90% of the appraised value of the related Mortgaged
Property or Properties (as determined by one or more Appraisals obtained by the Special Servicer (the cost of which shall be advanced
by the Master Servicer as a Property Advance unless such Property Advance would be a Nonrecoverable Advance)), minus such
downward adjustments as the Special Servicer may make in accordance with the Servicing Standard (without implying any obligation
to do so) based upon the Special Servicer’s review of the Appraisal and such other information as the Special Servicer
may deem appropriate and (B) all escrows, letters of credit and reserves in respect of such Mortgage Loan (or Serviced Whole
Loan) as of the date of the calculation over (ii) the sum, as of the Due Date occurring in the month of the date of determination
of, (A) to the extent not previously advanced by the Master Servicer or the Trustee, all unpaid interest on such Mortgage
Loan (or Serviced Whole Loan, if applicable) at a per annum rate equal to its Mortgage Loan Rate (and with respect to a
Serviced Whole Loan, interest on the related Serviced Companion Loan(s) at the related Mortgage Loan Rate), (B) all unreimbursed
Advances (which shall include, without limitation, (1) any Advances as to which the advancing party was reimbursed from a
source other than the related Mortgagor and (2) any Unliquidated Advances), with interest thereon at the Advance Rate in respect
of such Mortgage Loan (or Serviced Whole Loan) and (C) all currently due and unpaid real estate taxes and assessments, insurance
premiums and ground rents, unpaid Special Servicing Fees and all other amounts, due and unpaid with respect to such Mortgage Loan
(or Serviced Whole Loan) (which taxes, premiums, ground rents and other amounts have not been the subject of an Advance by the
Master Servicer or the Trustee, as applicable, and/or for which funds have not been escrowed). Promptly upon the occurrence of
an Appraisal Reduction Event (or a longer period so long as the Special Servicer is (as certified thereby to the Trustee in writing) diligently
and in good faith proceeding to obtain such), if an Appraisal has not been obtained within the immediately preceding nine (9) months
(or if the Special Servicer has determined in accordance with the Servicing Standard such Appraisal to be materially inaccurate),
the Special Servicer shall obtain an Appraisal, the costs of which shall be paid by the Master Servicer 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). The Master Servicer shall provide (via electronic delivery) the Special Servicer with information in
its possession that the Special Servicer reasonably requires to calculate or recalculate any Appraisal Reduction 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. None of the Master Servicer, the Trustee or the Certificate Administrator shall calculate or verify
Appraisal Reduction Amounts. On the first Determination Date occurring on or after the receipt of such Appraisal, the Special Servicer
shall calculate or adjust, as applicable, the Appraisal Reduction Amount to take into account such Appraisal and such information,
if any, reasonably requested by the Special Servicer from the Master Servicer reasonably required to calculate or recalculate the
Appraisal Reduction Amount. Notwithstanding the foregoing, if an Appraisal is required to be obtained in accordance with Section
3.10(a) of this Agreement but is not obtained within 120 days following the events described in the applicable clause of the
definition “Appraisal Reduction Event” (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

 

    	-8-

    	 

    

 

Reduction Amount will equal 25%
of the Stated Principal Balance of the related Mortgage Loan; provided that, upon receipt of an Appraisal by the Special
Servicer, however, the Appraisal Reduction Amount for such Mortgage Loan (or the related Serviced Whole Loan, if applicable) will
be recalculated in accordance with this definition without regard to this sentence. With respect to each Mortgage Loan (other than
a Non-Serviced Mortgage Loan) or Serviced Whole Loan as to which an Appraisal Reduction Event has occurred (unless the Mortgage
Loan (or Serviced Whole Loan) has become a Corrected Mortgage Loan (if a Servicing Transfer Event had occurred with respect to
the related Mortgage Loan (or Serviced Whole Loan)) and has remained current for three consecutive Monthly Payments, and with respect
to which no other Appraisal Reduction Event has occurred with respect thereto 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, that no new or updated Appraisal will be required if the Mortgage Loan, Serviced Whole
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 Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan and, in the case of a
Whole Loan, determined in accordance with the Co-Lender Agreement, and each of the Master Servicer and the Certificate Administrator
shall be entitled to rely conclusively on such determination by the Special Servicer. Upon completion, 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 Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan for which an Appraisal Reduction
Amount has been determined, such Appraisal Reduction Amount will be eliminated. In addition, with respect to any Mortgage Loan
(or Serviced Whole Loan, but not including any Non-Serviced Mortgage Loan), as to which an Appraisal Reduction Event has occurred,
such Mortgage Loan (or Serviced Whole Loan) shall no longer be subject to the Appraisal Reduction Amount if (a) such Mortgage
Loan (or Serviced Whole Loan) has become a Corrected Mortgage Loan (if a Servicing Transfer Event had occurred with respect to
the related Mortgage Loan (or Serviced Whole Loan)) and such Mortgage Loan (or Serviced Whole Loan) becomes and remains current
for three consecutive Monthly Payments and (b) no other Appraisal Reduction Event has occurred and is continuing.

 

Notwithstanding the foregoing,
with respect to any Non-Serviced Mortgage Loan, the Appraisal Reduction Amount with respect to the related Mortgage Loan and each
related Pari Passu Companion Loan shall be the pro rata portion of the “Appraisal Reduction Amount” relating
to such Mortgage Loan and each related Pari Passu Companion Loan, and calculated pursuant to the applicable Other Pooling and Servicing
Agreement by the applicable Other

 

    	-9-

    	 

    

 

Master Servicer or Other Special Servicer (or the Non-Serviced Mortgage Loan’s pro rata
share thereof). The parties hereto shall be entitled to rely on such calculations as reported to them by the applicable Other Special
Servicer or Other Master Servicer. By their acceptance of their Certificates, the Certificateholders will be deemed to have acknowledged
that each applicable Other Pooling and Servicing Agreement and the related Co-Lender Agreement taken together, provide that any
such “Appraisal Reduction Amount” will be calculated by the applicable Other Special Servicer or Other Master Servicer
under the applicable Other Pooling and Servicing Agreement.

 

Appraisal Reduction Amounts
with respect to a Serviced Whole Loan shall be allocated to the related Mortgage Loan and each related Pari Passu Companion Loan
on a pro rata and pari passu basis in accordance with the respective outstanding principal balances of such related
Mortgage Loan and each related Pari Passu Companion Loan.

 

“Appraisal Reduction
Event”: With respect to any Mortgage Loan (or Serviced Whole Loan, if applicable, but not with respect to any Non-Serviced
Mortgage Loan), the earliest of (i) the date on which such Mortgage Loan (or Serviced Whole Loan) becomes a Modified Asset,
(ii) the date on which such Mortgage Loan (or Serviced Whole Loan) is 60 days or more delinquent in respect of any Monthly
Payment, except for a Balloon Payment, (iii) solely in the case of a delinquent Balloon Payment, (A) the date occurring
60 days beyond the date on which that Balloon Payment was due (except as described in clause B below) or (B) if
the related Mortgagor has delivered to the Master Servicer or Special Servicer (and in either such case the Master Servicer or

Mortgage Loan for any one-month period preceding a related Due Date shall be the annualized rate at which interest would have to

period at a per annum rate equal to the related Mortgage Loan Rate minus the related Administrative Cost Rate; provided,
however, that, for purposes of calculating Pass-Through Rates and the WAC Rate, with respect to each Mortgage Loan that

period preceding the Due Date in March shall be determined taking into account the addition of any such Withheld Amounts.
Also notwithstanding the foregoing, for purposes of calculating Pass-Through Rates and the WAC Rate, the Net Mortgage Loan Rate
of any Mortgage Loan shall be determined without regard to any modification, waiver or amendment of the terms of such Mortgage
Loan, whether agreed to by the Special Servicer or an Other Special Servicer or resulting from a bankruptcy, insolvency or similar

Property Advance, as applicable, and taking into account factors such as all other outstanding Advances, either (a) has determined
that such Workout-Delayed Reimbursement Amounts, would not ultimately be recoverable from late collections or any other recovery

entitlement to reimbursement for such Advance. The determination as to the recoverability of any servicing advance previously made
or proposed to be made with respect to any Non-Serviced Mortgage Loan shall be made by the Other Master Servicer or Other Special
Servicer, as the case may be,

Section 2.01     Conveyance
of Mortgage Loans.

 

(a)          The Depositor, concurrently with the execution and delivery hereof, does hereby establish a trust to be designated as CSAIL
2015-C4 Commercial Mortgage Trust, appoint the Trustee to serve as trustee of such trust and assign, sell, transfer, set over and
otherwise convey to the Trustee (as holder of the Lower-Tier Regular Interests) in trust without recourse for the benefit of the
Certificateholders all the right, title and interest of the Depositor, including any security interest therein for the benefit
of the Depositor, in, to and under (i) the Mortgage Loans identified on the Mortgage Loan Schedule, (ii) Sections 2,
3, 4, 5 (other than Section 5(e) and 5(f)), 6 (other than Section 6(a)(i) and 6(a)(x)) and to the extent related to the
foregoing, 7, 11, 12, 13, 14, 16, 17, 18 and 23 of each Loan Purchase Agreement, and Sections 24 and 25 of the WDCPF I CS Loan
Purchase Agreement, (iii) the Co-Lender Agreements and (iv) all Escrow Accounts, Lockbox Accounts and all other assets
included or to be included in the Trust Fund for the benefit of the Certificateholders. Such assignment includes all interest and
principal received or receivable on or with respect to the Mortgage Loans (other than payments of principal, interest and other
amounts due and payable on the Mortgage Loans on or before the Cut-Off Date and excluding any Loan Seller Defeasance Rights and
Obligations with respect to the Mortgage Loans). Such assignment of each Mortgage Loan that is part of a Whole Loan is further
subject to the terms and conditions of the applicable Other Pooling and Servicing Agreement and each related Co-Lender Agreement.
The transfer of the Mortgage Loans and the related rights and property accomplished hereby is absolute and, notwithstanding Section
11.08 of this Agreement, is intended by the parties to constitute a sale.

(b)          In connection with the Depositor’s assignment pursuant to Section 2.01(a) of this Agreement, the Depositor
shall direct each Mortgage Loan Seller (pursuant to the related Loan Purchase Agreement) to deliver to and deposit with the
Custodian (on behalf of the Certificate Administrator), on or before the Closing Date, the Mortgage File for each Mortgage Loan,
with copies to be delivered within five (5) Business Days after the Closing Date, to the Master Servicer (other than with respect
to a Non-Serviced Mortgage Loan) and the Special Servicer; provided, however, that copies of any document in the
Mortgage File that also constitutes a Designated Servicing Document shall be delivered to the Master Servicer (other than with
respect to a Non-Serviced Mortgage Loan) on or before the Closing Date. 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 with the document delivery requirements of the related Loan Purchase Agreement and this Section 2.01(b). Notwithstanding
anything herein to the contrary, with respect to letters of credit (exclusive of those relating to any Non-Serviced Mortgage Loan),
the applicable Mortgage Loan Seller shall deliver to the Master Servicer and the Master Servicer shall hold the original (or copy,
if such original has been submitted by the applicable Mortgage Loan Seller to the issuing bank to effect an assignment or amendment
of such letter of credit (changing the beneficiary thereof to the Trust (in care of the Master Servicer) that may be required in
order for the Master Servicer to draw on such letter of credit on behalf of the Trust in accordance with the applicable terms thereof
and/or of the related Mortgage Loan Documents) and the applicable Mortgage Loan Seller shall be deemed to have satisfied any delivery
requirements of the related Loan Purchase Agreement and this Section 2.01(b) by delivering with respect to any letter(s)
of credit a copy thereof to the Custodian together with an Officer’s Certificate of the applicable Mortgage Loan Seller certifying
that such document has been delivered to the Master Servicer or an Officer’s Certificate from the Master Servicer certifying
that it holds the letter(s) of credit pursuant to this Section 2.01(b). If a letter of credit referred to in the previous
sentence is not in a form that would allow the Master Servicer to draw on such letter of credit on behalf of the Trust in accordance
with the applicable terms thereof and/or of the related Mortgage Loan Documents, the applicable Mortgage Loan Seller shall deliver
the appropriate assignment or amendment documents (or copies of such assignment or amendment documents if the related Mortgage
Loan Seller has submitted the originals to the related issuer of such letter of credit for processing) to the Master Servicer within
90 days of the Closing Date. The applicable Mortgage Loan Seller shall pay any costs of assignment or amendment of such letter(s)
of credit required in order for the Master Servicer to draw on such letter(s) of credit on behalf of the Trust and shall cooperate
with the reasonable requests of the Master Servicer 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 Trust.

 

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 Loan Purchase
Agreement that it shall record and file, or, in the case of Column, MC-Five Mile, BSPCC, Bancorp and WDCPF I CS, shall cause AMO
to record and file, at the related Mortgage Loan Seller’s expense, in the appropriate public office

 

    	-107-

    	 

    

 

for real property records
or UCC financing statements, as appropriate, each related assignment of Mortgage and assignment of Assignment of Leases, in favor
of the Trustee 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” and, with respect to any Mortgage
Loan to which the Custodian has agreed to record and file such documents, the Custodian shall promptly undertake to record or file
any such document upon its receipt thereof. This subsection (c) shall not apply to any Non-Serviced Mortgage Loan because
the documents referred to herein have been assigned to the Other Trustee.

 

The Depositor hereby
represents and warrants that the applicable Mortgage Loan Seller has covenanted in the related Loan Purchase Agreement as to each
Mortgage Loan (exclusive of a Non-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 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 Custodian shall obtain therefrom 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 Loan Purchase
Agreement) promptly to prepare or cause the preparation of a substitute therefor or to cure such defect, as the case may be, and
the Mortgage Loan Seller shall record or file, or cause AMO to record or file, or with respect to any assignments the Custodian
has agreed to file as described above, to deliver to the Custodian the substitute or corrected document. The Custodian shall upon
receipt from the applicable Mortgage Loan Seller cause the same to be duly recorded or filed, as appropriate.

 

(d)          In connection with the Depositor’s assignment pursuant to Section 2.01(a) of this Agreement, except with respect
to any Non-Serviced Mortgage Loan, the Depositor shall direct the applicable Mortgage Loan Seller (pursuant to the related Loan
Purchase Agreement) to deliver to and deposit (or cause to be delivered and deposited) with the Master Servicer within five
(5) Business Days after the Closing Date, (i) 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 or any related Serviced
Companion Loan, (B) are reasonably necessary for the ongoing administration and/or servicing of the Mortgage Loans

 

    	-108-

    	 

    

 

(including
any asset summaries related to the Mortgage Loans that were delivered to the Rating Agencies in connection with the rating of the
Certificates) and the Serviced Companion Loans or for evidencing or enforcing any of the rights of the holder of the Mortgage Loans
and the Serviced Companion Loans or holders of interests therein and (C) are in the possession or under the control of the
applicable Mortgage Loan Seller, together with (ii) all unapplied Escrow Payments and reserve funds in the possession or under
the control of the applicable Mortgage Loan Seller that relate to such Mortgage Loans or any related Serviced Companion Loans,
provided that copies of any document in the Mortgage File and any other document, record or item referred to above in this
sentence that constitutes a Designated Servicing Document shall be delivered to the Master Servicer on or before the Closing Date;
provided, further, that the applicable Mortgage Loan Seller shall not be required to deliver any draft documents,
privileged or other communications, credit underwriting, due diligence analyses or data, or internal worksheets, memoranda, communications
or evaluations. In addition, attached as Exhibit P to this Agreement is the Supplemental Servicer Schedule. 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 the Serviced Companion Loan, on behalf of and for the benefit of the applicable Companion
Loan Holder).

 

Each Loan Purchase Agreement
shall generally provide that as long as any Certificate is outstanding, the Seller shall, upon reasonable notice, reasonably cooperate
with the Trustee, the Master Servicer, the Special Servicer, the Custodian and/or the Depositor, as applicable, to provide all
items in the Mortgage Files and execute and/or deliver any documents that are necessary to effect the delivery, assignment and/or
recordation of any document relating to the Mortgage Loans at the time required for enforcement by the Trust.

 

(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 Loan Purchase Agreement, as in full force and effect, without amendment or modification,
on the Closing Date.

 

(f)          The Custodian with respect to the Serviced Whole Loans, shall also hold the related Mortgage File for the use and benefit
of the Companion Loan Holders.

 

(g)          The parties to this Agreement acknowledge and agree, with respect to each Mortgage Loan that is part of a Serviced Whole
Loan and a Non-Serviced Mortgage Loan, that the Trust assumes the obligations and rights of the holder of such Mortgage Loan under
the respective Co-Lender Agreement and any applicable Other Pooling and Servicing Agreement.

 

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

 

(i)          With respect to the Mortgage Loans secured by the Mortgaged Properties identified as Aloft Hotel - Downtown Denver, Country
Inn & Suites BWI, Hampton Inn Henderson NC, Homewood Suites - Brownsville and Country Inn & Suites Augusta on the Mortgage
Loan Schedule, which are each subject to one or more franchise agreements, each with a related comfort letter in favor of the respective
Mortgage Loan Seller that requires notice to or

 

    	-109-

    	 

    

 

request of the related franchisor to transfer or assign any related comfort letter
to the Trust or otherwise have a new comfort letter issued in the name of the Trust, the related Mortgage Loan Seller or its designee
will be required in the related Loan Purchase Agreement to provide any such required notice or make any such required request to
the related franchisor (with a copy of such notice or request to the Master Servicer) within 45 days of the Closing Date (or any
shorter period if required by the applicable comfort letter), and the Master Servicer shall use reasonable efforts in accordance
with the Servicing Standard to acquire such replacement comfort letter, if necessary (or to acquire any such new document or acknowledgement
as may be contemplated under the existing comfort letter).

 

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
Companion Loan Holders pursuant to Section 2.01(f) of this Agreement. With respect to each Serviced Whole Loan, the Custodian
shall also hold the portion of such Mortgage File that relates to the Companion Loan in such Serviced Whole Loan in trust for the
use and benefit of the related Companion Loan Holder. In connection with the foregoing, the 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 (l) of the definition of “Mortgage File”
are in its possession or the possession of the Custodian on its behalf, and (ii) the original Note(s) (or, if accompanied
by a lost note affidavit, the copy of such Note(s)) received by it or the Custodian with respect to such Mortgage Loan has
been reviewed by it or by the Custodian on its behalf 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 material 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 Section 2.01(c), Section 2.02(c)
and Section 2.02(d) of this Agreement and the terms of the respective 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 Whole Loan, to the related Companion
Loan Holder) that, as to each

 

    	-110-

    	 

    

 

Mortgage Loan then subject to this Agreement (except as specifically identified in any exception
report annexed to such certification, which exception report (and any updates thereto) shall also be electronically delivered in
Excel-compatible format): (i) all documents specified in clauses (1), (2), (3), (4) (other
than with respect to a Non-Serviced Mortgage Loan), (5), (7), (15) and (20) (for any Mortgage
Loan that is part of a Whole Loan) of the definition of “Mortgage File” are in its possession or the related Mortgage
Loan Seller has otherwise satisfied the delivery requirements in accordance with the related Loan Purchase Agreement; (ii) the
recordation/filing contemplated by Section 2.01(c) of this Agreement has been completed (based solely on receipt by
the Custodian of the particular recorded/filed documents); (iii) all documents received by it or the Custodian with respect
to such Mortgage Loan have been reviewed by it or the Custodian on its behalf 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. If the Custodian’s
obligation to deliver the certifications contemplated in this subsection terminates because two years have elapsed since the
Closing Date, the Custodian shall deliver a comparable certification to any party hereto, the related 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)         It is understood 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 a Non-Serviced Mortgage
Loan), (5), (7), (15) and (20) (for any Mortgage Loan that is part of a Whole Loan) of the definition
of “Mortgage File” have been received, appear regular on their face and such additional information as will be necessary
for delivering the certifications required by Section 2.02(a) and 2.02(b) of this Agreement.

 

    	-111-

    	 

    

 

(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 (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 Loan Purchase Agreement with respect to any Mortgage Loan (a “Breach”),
or (ii) the Special Servicer or the Depositor receives a Repurchase Communication of a request or demand for repurchase or replacement
of any Mortgage Loan alleging a Document Defect or Breach (any such request or demand, 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 Companion
Loan Holder (if applicable) and, for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section
11.13 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 (or any related REO Property) or the interests of the Certificateholders therein 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 Special Servicer shall determine
in its reasonable, good faith discretion and in accordance with the Servicing Standard, 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 Document Defect or Material Breach, then the Special Servicer shall give
prompt written notice thereof to the applicable Mortgage Loan Seller, the other parties hereto and the Controlling Class Representative
(prior to the occurrence and continuance of a Consultation Termination Event). Promptly upon becoming aware of any Material Document
Defect or Material Breach (including through a written notice given by the Master Servicer or the Special Servicer, as provided
above), the Master Servicer, if relating to a Non-Specially Serviced Loan, or the Special Servicer, if relating to a Specially
Serviced Loan, shall require the applicable Mortgage Loan Seller, not later than 90 days from the earlier of the applicable Mortgage
Loan Seller’s discovery or receipt of notice of, and receipt of a demand to take action with respect to, such Material Document
Defect or Material Breach, as the case may be (or, in the case of a Material Document Defect or Material Breach relating to a Mortgage
Loan not being a Qualified Mortgage, not later than 90 days from any party discovering such Material Document Defect or Material
Breach), to cure the same in all material respects (which cure shall include payment of losses and any

 

    	-112-

    	 

    

 

Additional Trust Fund Expenses
associated therewith) or, if such Material Document Defect or Material Breach, as the case may be, cannot be cured within
such 90 day period, either to (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 Mortgage Loan that is part of a Whole 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 Loan Purchase Agreement and this Agreement; provided,
however, that if (i) such Material Document Defect or Material Breach is capable of being cured but not within such
90 day period, (ii) such Material Document Defect or Material Breach 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 Document Defect or Material Breach 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 Document Defect or Material Breach 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 Document Defect or Material Breach will be cured
within such additional 90 day period); and provided, further, that, if any such Material Document 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 substitution obligations in respect of such Document 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 Document
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 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 

 

    	-113-

    	 

    

 

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.

 

If 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 (a “Repurchase Request Withdrawal”),
such party shall give written notice of such Repurchase Request Withdrawal 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
Companion Loan Holder (if applicable) and, for posting to the Rule 17g-5 Information Provider’s Website pursuant to
Section 11.13 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 the Special Servicer receives a Repurchase 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 Request Rejection”), then the Special Servicer shall (in
accordance with the following paragraph) give written notice of such Repurchase or Repurchase Request Rejection to 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 unless it is the party that notified the Special Servicer thereof, the Certificate Administrator and
the Trustee.

 

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 “15Ga-1 Notice”) shall be given no later than ten (10) Business Days
after receipt of a Repurchase Communication of such Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase
Request Rejection, as applicable, and shall include (i) the identity of the related Mortgage Loan, (ii) the date that
the Repurchase Communication regarding the Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request
Rejection was received, as applicable, (iii) if known, the basis for the Repurchase Request (as asserted in the Repurchase
Request) and (iv) in the case of 15Ga-1 Notices provided by the Special Servicer with respect to a Repurchase Request, a statement
as to whether the Special Servicer currently plans to pursue such Repurchase Request.

 

If the Trustee, the Certificate
Administrator, the Master Servicer, the Operating Advisor 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 (with respect to any Mortgage Loan or REO Mortgage Loan) and, with respect to any Mortgage Loan, prior
to the occurrence and continuance of a Consultation Termination Event, the Controlling Class Representative, and include the following
statement in the related correspondence: “This is a Repurchase Communication regarding [a “Repurchase Request”]
[a “Repurchase Request Withdrawal”] [a “Repurchase”] [a “Repurchase Request Rejection”] under
Section 2.03(a) of the Pooling and Servicing Agreement relating to the CSAIL 2015-C4 Commercial Mortgage Trust, Commercial
Mortgage Pass Through Certificates, Series 2015-C4,

 

    	-114-

    	 

    

 

requiring action by you as the recipient of such [Repurchase Request] [Repurchase
Request Withdrawal] [Repurchase] [Repurchase Request Rejection] thereunder”. Upon receipt of any Repurchase Communication
of a Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection by the Special Servicer pursuant
to the foregoing provisions of this paragraph, the Special Servicer shall be deemed to be the recipient of such Repurchase Communication
of such Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection, and the Special Servicer
shall comply with the notice procedures set forth in the preceding paragraphs of this Section 2.03(a) with respect to such
Repurchase Communication of such Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection.

 

No Person that is required
to provide a 15Ga-1 Notice pursuant to this Section 2.03(a) (a “15Ga-1 Notice Provider”) shall be required
to provide any information in a 15Ga-1 Notice protected by the attorney-client privilege or attorney work product doctrines. Each
Loan Purchase Agreement will provide that (i) any 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 15Ga-1 Notice Provider and (B) no information provided pursuant to this Section 2.03(a) by a 15Ga-1 Notice Provider
in a 15Ga-1 Notice shall be deemed to constitute a waiver or defense to the exercise of any legal right the 15Ga-1 Notice Provider
may have with respect to the related Loan Purchase Agreement, including with respect to any Repurchase Request that is the subject
of a 15Ga-1 Notice.

 

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

 

With respect to any Non-Serviced
Mortgage Loan, the parties to this Agreement agree that if a “material document defect” exists with respect to the
related Non-Serviced Companion Loan under the Other Pooling and Servicing Agreement that governs servicing of the related Whole
Loan and the related Mortgage Loan Seller (or other responsible repurchasing entity) repurchases such related Companion Loan pursuant
to or as contemplated by such Other Pooling and Servicing Agreement, then such Mortgage Loan Seller shall also repurchase such
Non-Serviced Mortgage Loan; provided, however, that such repurchase obligation does not apply to any “material
document defect” related solely to the promissory note for such Companion Loan.

 

(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 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 and except a Material Document Defect that causes any Mortgage Loan to fail to be a “qualified
mortgage” within the meaning of Code Section 860G(a)(3)) shall be considered to be a Material Document Defect unless the
document

 

    	-115-

    	 

    

 

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 Mortgage Loan Seller, upon delivery to each of them of a receipt executed by the applicable
Mortgage Loan Seller evidencing such repurchase or substitution, all portions of the Mortgage File and other documents (including,
without limitation, the Servicing File), and all escrows 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 and the Custodian shall be conditioned upon its receipt (and such receipt shall be deemed to be the
Master Servicer’s direction to the Trustee and the Custodian to so tender) 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 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 a Non-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.

 

(d)         The related Loan Purchase Agreement provides the sole remedies available to the Certificateholders, or the Certificate Administrator
or the Trustee on behalf of the Certificateholders, respecting any Document Defect or Breach with respect to any Mortgage Loan.

 

(e)         If (i) any Crossed Underlying Loan is required to be repurchased or substituted for in the manner described in this
Section 2.03 and (ii) the applicable Defect or Breach does not constitute a Defect or Breach, as the case may be, as
to any other Crossed Underlying Loan in the related Crossed Mortgage Loan Group (without regard to this paragraph), then the applicable
Defect or Breach, as the case may be, will be deemed to constitute a Defect or Breach, as the case may be, as to any other Crossed
Underlying Loan in the related Crossed Mortgage Loan Group for purposes of this paragraph, and the related Mortgage Loan Seller
will be required to repurchase or substitute for such other Crossed

 

    	-116-

    	 

    

 

Underlying Loan(s) in the related Crossed Mortgage Loan Group
as provided in Section 2.03(a) unless such other Crossed Underlying Loans satisfy the Crossed Underlying Loan Repurchase
Criteria. In the event that the remaining Crossed Underlying Loans in such Crossed Mortgage Loan Group satisfy the aforementioned
criteria, the applicable Mortgage Loan Seller may elect either to repurchase or substitute for only the affected Crossed Underlying
Loan(s) as to which the related Breach or Defect exists or to repurchase or substitute for all of the Crossed Underlying Loans
in the related Crossed Mortgage Loan Group. Any reserve or other cash collateral or letters of credit securing the Crossed Underlying
Loans shall be allocated among the related Crossed Underlying Loans in accordance with the related Mortgage Loan documents or otherwise
on a pro rata basis based upon their outstanding Stated Principal Balances. Except as provided in this Section 2.03(e)
and Section 2.03(f), all other terms of the related Mortgage Loans shall remain in full force and effect without any modification
thereof.

 

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

 

(g)         With respect to any Crossed Underlying Loan, to the extent that the applicable Mortgage Loan Seller is required to repurchase
or substitute for such Crossed Underlying Loan in the manner prescribed in Section 2.03(a) while the Trustee continues
to hold any other Crossed Underlying Loans in the related Crossed Mortgage Loan Group, the applicable Mortgage Loan Seller and
the Master Servicer or, with respect to a Specially Serviced Mortgage Loan, the Special Servicer, on behalf of the Trustee, as
assignee of the Depositor, will, as set forth in the related Mortgage Loan Purchase Agreement, forbear from enforcing any remedies
against the other’s Primary Collateral but each will be permitted to exercise remedies against the Primary Collateral securing
its respective related Mortgage Loans, including with respect to the Trustee, the Primary Collateral securing the Mortgage Loans
still held by the Trustee, so long as such exercise does not materially impair the ability of the other party to exercise its
remedies against its Primary Collateral. If the exercise of the remedies by one party would materially impair the ability of the
other party to exercise its remedies with respect to the Primary Collateral securing the Crossed Underlying Loans held by such
party, then both parties have agreed in the related Mortgage Loan Purchase Agreement to forbear from exercising such remedies
until the Mortgage Loan documents evidencing and securing the relevant Mortgage Loan can be modified in a manner that complies
with the related Mortgage Loan Purchase Agreement to remove the threat of material impairment as a result of the exercise of remedies.

(a)         The Master Servicer (with respect to the Mortgage Loans (other than any Non-Serviced Mortgage Loan, which will be serviced

(with respect to the Specially Serviced Loans), each as an independent contractor, shall service and administer the Mortgage Loans
(other than any Non-Serviced Mortgage Loan, which will be serviced pursuant to the applicable Other Pooling and Servicing Agreement)
and the Serviced Companion Loans on behalf of the Trust Fund and the Trustee (for the benefit of the Certificateholders or, with
respect to each Serviced Whole Loan, for the benefit of the Certificateholders and the related Serviced Companion Loan Holder(s)
as a collective whole as if such Certificateholders and Serviced Companion Loan Holder(s) constituted a single lender, subject
to the terms and conditions of the Co-Lender Agreements) as determined in the good faith and reasonable judgment of the Master
Servicer or the Special Servicer, as the case may be, in accordance with: (i) any and all applicable laws; (ii) the express
terms of this Agreement, the respective Mortgage Loans or Serviced Whole Loans and, in the case of the Serviced Whole Loans, the

    	-128-

    	 

    

 

the Servicing Standard. To the extent
consistent with the foregoing and subject to any express limitations set forth in this Agreement and any related Co-Lender Agreement
or mezzanine loan intercreditor agreement, the Master Servicer and the Special Servicer shall seek to maximize the timely and complete
recovery of principal and interest, on the Mortgage Loans (other than any Non-Serviced Mortgage Loan) and the Serviced Companion
Loans. Subject only to the Servicing Standard, the Master Servicer and Special Servicer shall have full power and authority, acting
alone or, in the case of the Master Servicer only, through Sub-Servicers (subject to paragraph (c) of this Section 3.01
and to Section 3.02 of this Agreement), to do or cause to be done any and all things in connection with such servicing and
administration which it may deem consistent with the Servicing Standard and, in its judgment exercised in accordance with the Servicing
Standard, in the best interests of the Certificateholders and, in the case of a Serviced Whole Loan, the related Serviced Companion
Loan Holder(s) (as a collective whole as if such Certificateholders and, in the case of a Serviced Whole Loan, the related Serviced
Companion Loan Holder(s) constituted a single lender, subject to the terms and conditions of the Co-Lender Agreements), including,
without limitation, with respect to each Mortgage Loan and Serviced Companion Loan, (A) to prepare, execute and deliver, on behalf
of the Certificateholders, the Serviced Companion Loan Holders, the Trustee, the Certificate Administrator and the Custodian or
any of them: (i) any and all financing statements, continuation statements and other documents or instruments necessary to
maintain the lien on each Mortgaged Property and related collateral; (ii) subject to Section 3.08, 3.09, 3.10
and 3.24 of this Agreement, any modifications, waivers, consents or amendments to or with respect to any documents contained
in the related Mortgage File or defeasance of the Mortgage Loan or Companion Loan; and (iii) any and all instruments of satisfaction
or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Mortgage
Loans (and related Serviced Companion Loans) and the Mortgaged Properties; and (B) to direct, manage, prosecute and/or defend
any action, suit or proceeding of any kind filed in the name of the Trust Fund acting by or through the Master Servicer or the
Special Servicer, as applicable, in their respective capacity on behalf of the Trustee or the Trust, subject to clause (i)
of the following paragraph. Notwithstanding the foregoing, neither the Master Servicer nor the Special Servicer shall modify, amend,
waive or otherwise consent to any change of the terms of any Mortgage Loan or Companion Loan except under the circumstances described
in Section 3.08, 3.09, 3.10 and 3.24 of this Agreement or in Section 3.03 of this Agreement.
The Master Servicer and Special Servicer shall service and administer the Mortgage Loans (other than any Non-Serviced Mortgage
Loan) and the Companion Loans in accordance with applicable law and the terms hereof, the related Mortgage Loan Documents and the
Co-Lender Agreements and shall provide to the Mortgagors any reports required to be provided to them thereby.

 

Subject to Section
3.11 of this Agreement, the Trustee shall, upon the receipt of a written request of a Servicing Officer, execute and deliver
to the Master Servicer or Special Servicer any powers of attorney substantially in the form of Exhibit AA-1 to this
Agreement or such other form as mutually agreed to by the Trustee and the Master Servicer (in the case of the Master Servicer)
or Exhibit AA-2 to this Agreement or such other form as mutually agreed to by the Trustee and the Special Servicer
(in the case of the Special Servicer), as applicable, and other documents reasonably acceptable to the Trustee prepared by the
Master Servicer and Special Servicer and necessary or appropriate (as certified in such written request) to enable the Master Servicer
and Special Servicer to carry out their servicing and administrative duties hereunder. Notwithstanding anything contained herein
to the contrary, none of the Master Servicer, the

  

    	-129-

    	 

    

 

Special Servicer
or any Sub-Servicer shall, without the Trustee’s written consent: (i) initiate any action, suit or proceeding solely
under the Trustee’s name without indicating the Master Servicer’s or Special Servicer’s, as applicable, representative
capacity, unless prohibited by any requirement of the applicable jurisdiction in which any such action, suit or proceeding is
brought and if so prohibited, in the manner required by such jurisdiction (provided that the Master Servicer or the Special
Servicer, as applicable, shall then provide five (5) Business Days’ written notice to the Trustee of the initiation of such
action, suit or proceeding (or such shorter time period as is reasonably required in the judgment of the Master Servicer or the
Special Servicer, as applicable, made in accordance with the Servicing Standard) prior to filing such action, suit or proceeding),
and shall not be required to obtain the Trustee’s consent or indicate the Master Servicer’s or the Special Servicer’s,
as applicable, representative capacity; or (ii) take any action with the intent to cause, and that actually causes, the Trustee
to be registered to do business in any state. Each of the Master Servicer, the Special Servicer and any Sub-Servicer shall indemnify
the Trustee for any and all costs, liabilities and expenses incurred by the Trustee in connection with the negligent or willful
misuse of such powers of attorney by the Master Servicer or the Special Servicer or its agents or subcontractors, as applicable.

 

(b)         Unless otherwise provided in the related Mortgage Loan Documents, the Master Servicer shall apply any partial principal
prepayment received on a Mortgage Loan (other than any Non-Serviced Mortgage Loan) or Serviced Companion Loan on a date other than
a Due Date, to the principal balance of such Mortgage Loan as of the Due Date immediately following the date of receipt of such
partial principal prepayment. Unless otherwise provided in the related Mortgage Loan Documents, the Master Servicer shall apply
any amounts received on “government securities” within the meaning of Section 2(a)(16) of the Investment Company
Act, or any other securities that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii) (which shall not be redeemed
by the Master Servicer prior to the maturity thereof) in respect of such a Mortgage Loan or Serviced Companion Loan being
defeased pursuant to its terms to the principal balance of and interest on such Mortgage Loan or Serviced Companion Loan as of
the Due Date immediately following the receipt of such amounts. If with respect to any Mortgage Loan (or Serviced Whole Loan) the
related Mortgage Loan Documents permit the lender to (but do not require the lender to), at its option, prior to an event of default
under the related Mortgage Loan (or Serviced Whole Loan), apply amounts held in any reserve account as a prepayment or hold such
amounts in a reserve account, the Master Servicer shall not apply such amounts as prepayment, and instead 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 Mortgage Loan (or Serviced Whole Loan); provided that any such amounts may be used, if permitted under the related
Mortgage Loan Documents, to defease the related Mortgage Loan (or Serviced Whole Loan) or, upon an event of default under the related
Mortgage Loan (or Serviced Whole Loan), to prepay the Mortgage Loan (or Serviced Whole Loan).

 

(c)         The Master Servicer may enter into Sub-Servicing Agreements with third parties with respect to any of its obligations hereunder,
provided that (i) any such agreement shall be consistent with the provisions of this Agreement, (ii) any such
agreement shall be consistent with the Servicing Standard, (iii) the Depositor has consented to the related Sub-Servicer,
(iv) any such agreement shall provide that, following receipt of the applicable Loan Purchase Agreement from the Depositor,
the Master Servicer shall provide a copy of the applicable Loan Purchase Agreement to the related Sub-Servicer, and that such Sub-Servicer

 

    	-130-

    	 

    

 

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) with respect to any Sub-Servicing Agreement entered into after the Closing
Date, if such Sub-Servicer is a Servicing Function Participant or an Additional Servicer, such Sub-Servicer, at the time the related
Sub-Servicing Agreement is entered into, is not a Prohibited Party and (vi) the Master Servicer shall notify the applicable
Mortgage Loan Seller of any such agreement. 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 pay the servicing fees of any Sub-Servicer and shall
provide a copy of each Sub-Servicing Agreement (and any assignment thereof) to the Trustee. Any Sub-Servicing Agreement entered
into by the Master Servicer shall provide that it may be assumed by the Trustee, if the Trustee has assumed the duties of 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. The Special Servicer may not enter into
Sub-Servicing Agreements; provided that, if and to the extent Midland Loan Services, a Division of PNC Bank, National Association
or its successor-in-interest is terminated as Special Servicer by the Controlling Class Representative without cause (i.e.,
not as a result of a Servicer Termination Event) and Midland Loan Services, a Division of PNC Bank, National Association or its
successor-in-interest otherwise satisfies all of the eligibility requirements applicable to special servicers contained in this
Agreement, Midland Loan Services, a Division of PNC Bank, National Association or its successor-in-interest may be appointed as
a sub-special servicer of a successor Special Servicer appointed by the Controlling Class Representative, subject to the consent
of the Controlling Class Representative.

 

Any Sub-Servicing Agreement,
and any other transactions or services relating to the Mortgage Loans and/or Serviced Whole Loans involving a Sub-Servicer, shall
be deemed to be between the Master Servicer and such Sub-Servicer alone, and the Trustee, the Certificate Administrator, the Custodian,
the Operating Advisor, the Trust Fund and the Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to 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.

 

(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, as
applicable, succeed to all of the rights and obligations of the Master Servicer under any Sub-Servicing Agreement entered into
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

 

    	-131-

    	 

    

 

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.

 

In the event that the
Trustee or any successor Master Servicer, assumes the servicing obligations of the Master Servicer, upon request of the Trustee,
or such successor Master Servicer, as applicable, the Master Servicer shall at its own expense deliver or cause to be delivered
to the Trustee or such successor Master Servicer all documents and records relating to any Sub-Servicing Agreement and the Mortgage
Loans then being serviced thereunder and an accounting of amounts collected and held by it, if any, and will otherwise use its
reasonable efforts to effect the orderly and efficient transfer of any Sub-Servicing Agreement to the Trustee or the successor
Master Servicer, as applicable.

 

(e)         The parties hereto acknowledge that each Serviced Whole Loan is subject to the terms and conditions of the related Co-Lender
Agreement and recognize the respective rights and obligations of the Trust, as holder of the related Mortgage Loan, and of the
related Companion Loan Holder, including: (i) with respect to the allocation of collections on or in respect of such Whole Loan,
and the making of remittances, to the Trust, as holder of the related Mortgage Loan, and to the related Companion Loan Holder(s);
(ii) with respect to the allocation of expenses and losses relating to such Whole Loan to the Trust, as holder of the related Mortgage
Loan, and to the related Companion Loan Holders; and (iii) the consultation rights of the related Companion Loan Holder or
its Companion Loan Holder Representative. With respect to any Serviced Whole Loan, the Master Servicer (if such Serviced Whole
Loan is a non-Specially Serviced Loan) or the Special Servicer (if such Serviced Whole Loan has become a Specially Serviced Loan
or the related Mortgaged Property has been converted to an REO Property) shall (i) prepare and provide to such Companion Loan
Holder all notices, reports, statements and communications to be delivered by the holder of the related Mortgage Loan under the
related Co-Lender Agreement; and (ii) perform all duties and obligations to be performed by a servicer and perform all servicing-related
duties and obligations to be performed by the holder of the related Mortgage Loan pursuant to the related Co-Lender Agreement and/or
as set forth herein. All provisions required to be included herein by the related Co-Lender Agreement are deemed included and shall
be enforceable to the same extent as if set forth herein. In the event of any conflict between this Agreement and a Co-Lender Agreement,
the terms of such Co-Lender Agreement shall control with respect to the related Serviced Whole Loan.

 

(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 Whole Loan is no longer part of the Trust Fund, neither the Master Servicer nor the Trustee, as the case may
be, shall have any obligation to make any Property Advance on such Serviced Whole Loan. If pursuant to the foregoing sentence,
the Master Servicer or the Trustee does not intend to make a Property Advance with respect to a Serviced Whole Loan that the Master
Servicer or the Trustee would have made if the related Mortgage Loan or REO Property were still part of the Trust Fund, the Master
Servicer or the Trustee, as the case may be, shall promptly notify the holder of the related 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

 

    	-132-

    	 

    

 

the time the Mortgage Loan relating
to a Serviced Whole Loan is removed from the Trust Fund, the Master Servicer or the Trustee, as the case may be, shall deliver
to the related Companion Loan Holder (or the master servicer of any securitization of the related 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 Mortgagor 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)         With respect to the Mortgage Loans set forth on Exhibit HH, to the extent required under any Mortgage 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 Mortgage Loan Documents.

 

(h)         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 any Non-Serviced Mortgage Loan and any Non-Serviced Companion Loan related to such Non-Serviced Mortgage
Loan are limited by and subject to the terms of the related Co-Lender Agreement and this Agreement and the rights of an Other Master
Servicer and an Other Special Servicer with respect thereto under the applicable Other Pooling and Servicing Agreement. The parties
further recognize the respective rights and obligations of an Other Trustee and/or the related Companion Loan Holders (or the representatives
thereof) under each respective Co-Lender Agreement including with respect to (i) the allocation of collections on or in respect
of a Non-Serviced Whole Loan in accordance with the related Co-Lender Agreement, (ii) the purchase of a Non-Serviced Whole
Loan or related Non-Serviced Mortgage Loan by the related Non-Serviced Companion Loan Holder or their designees in accordance with
the respective Co-Lender Agreement to the extent provided therein and (iii) any cure rights that a Non-Serviced Companion
Loan Holder may exercise, if applicable, in accordance with the related Co-Lender Agreement. The Trustee shall cooperate with the
Master Servicer in connection with the enforcement of the rights by the Trustee on behalf of the Trust (as holder of each Non-Serviced
Mortgage Loan) under each related Co-Lender Agreement and each applicable Other Pooling and Servicing Agreement. The Master Servicer
(with the cooperation of and under the power of attorney granted by, the Trustee) shall take such actions as it shall deem reasonably
necessary to facilitate the servicing of the related Non-Serviced Companion Loan by the related Other Master Servicer and the related
Other 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 Other Master Servicer or Other Special Servicer under
the applicable Other Pooling and Servicing Agreement.

 

To the extent that the
Trust, as holder of a Non-Serviced Mortgage Loan for the benefit of the Certificateholders, is entitled to consult regarding,
to consent to or approve any modification, waiver or amendment of, or other loan level action related to, such Non-Serviced Mortgage
Loan, such consultation, consent or approval rights shall be exercised by the Controlling Class Representative or Operating Advisor,
as applicable, as provided in Section 3.01(j) and Section 3.24(i), subject to the consent and/or consultation rights
any other applicable Person, as provided in such Sections. 

 

    	-133-

    	 

    

 

In addition to such consultation,
consent or approval rights, the Controlling Class Representative (if no Control Termination Event has occurred and is continuing)
and the Operating Advisor (if a Control Termination Event has occurred and is continuing), on behalf of the Trust, as holder of
a Non-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 Other Pooling and Servicing Agreement, to attend
(in-person or telephonically) annual meetings with the related Other Master Servicer or Other Special Servicer, as applicable,
upon reasonable notice and at times reasonably acceptable to the related Other Master Servicer or Other Special Servicer, as applicable,
for the purpose of discussing servicing issues related to the Non-Serviced Mortgage Loan.

 

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

 

(i)          The parties hereto acknowledge that the Non-Serviced Whole Loan is subject to the terms and conditions of the related Co-Lender
Agreement and further acknowledge that, pursuant to the related Co-Lender Agreement, (i) the related Non-Serviced Mortgage
Loan and Non-Serviced Companion Loan are to be serviced and administered by an Other Master Servicer and Other Special Servicer
in accordance with the applicable Other Pooling and Servicing Agreement, and (ii) in the event that the applicable Non-Serviced
Companion Loan is no longer part of the trust fund created by the applicable Other Pooling and Servicing Agreement and the related
Non-Serviced Mortgage Loan remains an asset of the Trust Fund, then, as set forth in the related Co-Lender Agreement, the related
Whole Loan shall be serviced in accordance with the applicable provisions of the applicable Other Pooling and Servicing Agreement
as if such agreement was still in full force and effect with respect to the related Whole Loan, 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 Non-Serviced Mortgage Loan.

 

(j)          The parties hereto acknowledge that the Non-Serviced Mortgage Loan is subject to the terms and conditions of the related
Co-Lender Agreement. The parties hereto recognize the respective rights and obligations of the “Initial Note Holders”
and “Note Holders” under the related Co-Lender Agreement for such Non-Serviced Mortgage Loan, including with respect
to the allocation of collections and losses on or in respect of such Non-Serviced Mortgage Loan and the related Non-Serviced Companion
Loan and the making of payments to

 

    	-134-

    	 

    

 

the “Initial Note Holders” and “Note Holders” in accordance with such
Co-Lender Agreement and the Other Pooling and Servicing Agreement. The parties hereto further acknowledge that, pursuant to the
related Co-Lender Agreement, the Non-Serviced Mortgage Loan and the related Non-Serviced Companion Loan are to be serviced and
administered by the related Other Master Servicer and the related Other Special Servicer in accordance with the related Other Pooling
and Servicing Agreement. Although the Non-Serviced Mortgage Loan is not serviced and administered hereunder, the Master Servicer
and the Special Servicer hereunder for each such Non-Serviced Mortgage Loan shall have certain duties as set forth herein and shall
constitute the “Master Servicer” and “Special Servicer” hereunder with respect to such Non-Serviced Mortgage
Loan.

 

If
there are at any time amounts due from the Trust, as holder of the Non-Serviced Mortgage Loan, to any party under the related
Co-Lender Agreement or the applicable Other Pooling and Servicing Agreement, the Master Servicer shall pay such amounts out of
the Collection Account. If a party to the applicable Other Pooling and Servicing Agreement related to a Non-Serviced Mortgage
Loan requests the Master Servicer, Special Servicer, Trustee, Certificate Administrator or Custodian to consult regarding, consent
to or approve a modification, waiver or amendment of, or other loan-level action related to, such Non-Serviced Mortgage Loan (and
a modification, waiver or amendment of the applicable Other Pooling and Servicing Agreement and/or the related Co-Lender Agreement
shall not be subject to the operation of this sentence but shall instead be subject to the operation of the second succeeding
sentence), then the Master Servicer shall promptly forward any such request it receives to the Special Servicer and the Special
Servicer shall promptly deliver a copy of such request it receives (from the Master Servicer or directly from a party to the applicable
Other Pooling and Servicing Agreement) to the Controlling Class Representative (with respect to any consent rights, if no Control
Termination Event has occurred and is continuing, and with respect to any consultation rights, if no Consultation Termination
Event has occurred) or the Operating Advisor (with respect to any consultation rights, if a Consultation Termination Event has
occurred), and the Controlling Class Representative or Operating Advisor (as applicable) shall exercise such right of consultation
or consent, as applicable, as provided in Section 3.24(i); provided, however, that (i) insofar as any other
Person (including without limitation the Controlling Class Representative or the Operating Advisor) would have consent and/or
consultation rights hereunder with respect to a similar modification, waiver or amendment of, or other loan level action related
to, a Mortgage Loan that is a Serviced Mortgage Loan, such Person shall likewise have the same consent and/or consultation rights,
subject to the same procedures, conditions and/or restrictions, with respect to such modification, waiver or amendment of, or
other loan level action related to, such Non-Serviced Mortgage Loan as set forth in this Agreement and (ii) if such Non-Serviced
Mortgage Loan were serviced hereunder and such action would not be permitted without Rating Agency Confirmation, then the Controlling
Class Representative shall not exercise such right of consent without first having received such Rating Agency Confirmation (payable
at the expense of the party requesting such approval, if a Certificateholder or a party to this Agreement, otherwise from the
Collection Account). If a Responsible Officer of the Trustee receives actual notice of a “servicer termination event”
under the applicable Other Pooling and Servicing Agreement, then the Trustee shall notify the Master Servicer, the Special Servicer
and the Controlling Class Representative (in writing), and the Master Servicer or the Special Servicer, as applicable, shall instruct
the Other Trustee to terminate the Other Master Servicer or Other Special Servicer, as applicable, if so directed in writing by
the Controlling

 

    	-135-

    	 

    

 

Class
Representative (prior to the occurrence of a Control Termination Event) (provided that the Master Servicer and the Special Servicer
shall only be required to comply with such instructions if such instructions are in accordance with the applicable Other Pooling
and 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
Other Pooling and Servicing Agreement) or if the Master Servicer or Special Servicer, as applicable, is not permitted by the applicable
Other Pooling and Servicing Agreement to follow such instructions or if a Control Termination Event has occurred, then the Master
Servicer or Special Servicer, as applicable, shall instruct the Other Trustee to terminate the Other Master Servicer or Other
Special Servicer, as applicable (to the extent permitted by the applicable Other Pooling and Servicing Agreement), if so directed
in writing by the Holders of the Certificates entitled to a majority of the Voting Rights (such direction communicated to the
Master Servicer or Special Servicer, as applicable, by the Certificate Administrator upon receipt) within a reasonable period
of time that does not exceed such response time as is afforded under the applicable Other Pooling and Servicing Agreement. If
the Trustee receives a written request from any party to the applicable Other Pooling and Servicing Agreement for consent to or
approval of a modification, waiver or amendment of the applicable Other Pooling and 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 Other Pooling
and Servicing Agreement in effect as of the Closing Date or a change in servicer under the applicable Other Pooling and Servicing
Agreement, then the Trustee (if it shall have received a prior Rating Agency Confirmation from each Rating Agency (at the expense
of the party requesting such approval of the Trustee, if a Certificateholder or a party to this Agreement and otherwise from the
Collection Account) with respect to such consent or approval) shall grant such consent or approval; provided that unless
a Control Termination Event has occurred and is continuing, the Trustee shall obtain the consent of the Controlling Class Representative
prior to granting any such consent. The Trustee shall not take any action and shall not be liable for failing to take any action
except upon obtaining such consent and direction. Prior to granting or withholding any such consent, the Trustee shall not take
any action and shall not be liable for failing to take any action except upon obtaining such consent and direction. During the
continuation of any termination event under the applicable Other Pooling and Servicing Agreement, each of the Trustee, 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 or the Trustee in connection with such enforcement
shall be paid by the Master Servicer out of the Collection Account. The Trustee, the Special Servicer and the Master Servicer
shall each promptly forward all material notices or other communications delivered to it in connection with the applicable Other
Pooling and Servicing Agreement to the other such party, the Depositor and (prior to the occurrence of a Consultation Termination
Event) the Controlling Class Representative 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 11.13) if the related Non-Serviced Mortgage Loan were a Mortgage Loan
that is serviced and administered under this Agreement, to the Rule 17g-5 Information Provider (who shall

 

    	-136-

    	 

    

 

promptly
post such notice to the Rule 17g-5 Information Provider’s Website in accordance with Section 11.13). 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 Non-Serviced Mortgage Loan
shall be dependent on its receipt of the corresponding information and collections from the applicable Other Master Servicer or
the applicable Other Special Servicer. Each of the Trustee, the Certificate Administrator, the Master Servicer and the Special
Servicer shall reasonably cooperate with the Controlling Class Representative or the Operating Advisor, as applicable, to facilitate
the exercise by the Controlling Class Representative or the Operating Advisor, as applicable, of any consent, approval or consultation
rights set forth in this Section 3.01(j); provided, however, that the Trustee, the Certificate Administrator,
the Master Servicer and Special Servicer 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.
  

(k)         With
respect to any Non-Serviced Mortgage Loan, the parties to this Agreement agree as follows:

 

(i)          pursuant to the applicable Other Pooling and Servicing Agreement, the related Other Master Servicer is obligated to make
“Property Advances” and incur “Additional Trust Fund Expenses” (or such other similar term, each as defined
in the applicable Other Pooling and Servicing Agreement) with respect to any Non-Serviced Mortgage Loan; the Trust shall be responsible
for its pro rata share of any “Nonrecoverable Servicing Advances” (and accrued and unpaid interest thereon)
and any “Additional Trust Fund Expenses” (but not any interest on “P&I Advances”) (each as defined
in the applicable Other Pooling and Servicing Agreement), but only to the extent that they relate to servicing and administration
of a Non-Serviced Mortgage Loan, including without limitation, any unpaid “Special Servicing Fees”, “Liquidation
Fees” and “Workout Fees” (each as defined in the applicable Other Pooling and Servicing Agreement) relating to
a Non-Serviced Mortgage Loan; and in the event that the funds received with respect to any Non-Serviced Whole Loan are insufficient
to cover “Property Advances” or “Additional Trust Fund Expenses” (each as defined in the applicable Other
Pooling and Servicing Agreement), (i) the Master Servicer shall, promptly following notice from the Other Master Servicer
or the Other Special Servicer, pay or reimburse the Other Master Servicer, the Other Special Servicer, the Other Certificate Administrator
or an Other Trustee, as applicable (such reimbursement, to the extent owed to an Other Special Servicer, an Other Certificate Administrator
or an Other Trustee, may be paid by the Master Servicer to an Other Master Servicer, who shall pay such amounts to an Other Special
Servicer, an Other Certificate Administrator or an Other Trustee, as applicable), out of general funds in the Collection Account
for the Trust’s pro rata share of any such “Nonrecoverable Servicing Advances” (together with advance
interest thereon) and/or “Additional Trust Fund Expenses” (each as defined in the applicable Other Pooling and Servicing
Agreement)), and (ii) if the applicable Other Pooling and Servicing Agreement permits the Other Master Servicer, the Other
Special Servicer, the Other Certificate Administrator or the Other Trustee to reimburse itself from the Other Securitization Trust’s
general collections, then the parties to this Agreement hereby acknowledge and agree that the Other Master Servicer, the Other
Special Servicer, the Other Certificate Administrator or the Other Trustee, as applicable, may do so and the

 

    	-137-

    	 

    

 

Master Servicer shall
be required to, promptly following notice from the Other Master Servicer, the Other Special Servicer or the Other Trustee, reimburse
the Other Securitization Trust out of general funds in the Collection Account for the Trust’s pro rata share of any
such “Nonrecoverable Servicing Advances” (together with advance interest thereon) and/or “Additional Trust Fund
Expenses” (each as defined in the applicable Other Pooling and Servicing Agreement);

 

(ii)         any Other Securitization Trust and each of the parties to the applicable Other Pooling and Servicing Agreement shall be
indemnified with respect to losses, costs and expenses relating to the related Non-Serviced Mortgage Loan as and to the same extent
the Other Trust is required to indemnify each of such Persons in respect of other mortgage loans in the Other Trust pursuant to
the terms of Other Pooling and Servicing Agreement by the Trust to the extent of the Trust’s pro rata share of any
and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liabilities,
fees and expenses incurred in connection with the servicing and administration of the related Non-Serviced Mortgage Loan and the
related Mortgaged Property under the related Other Pooling and Servicing Agreement, and to the extent amounts on deposit in the
“Serviced Whole Loan Custodial Account” (or such other similar term, as defined in the applicable Other Pooling and
Servicing Agreement) are insufficient for reimbursement of such amounts, the Master Servicer shall, promptly following notice from
the related Other Master Servicer, reimburse each of such applicable Persons for the Trust’s pro rata share of the
insufficiency out of general funds in the Collection Account;

 

(iii)        in the event of a conflict between the provisions of this Agreement and the related Co-Lender Agreement, the related Co-Lender
Agreement shall prevail; provided that in no event shall the Master Servicer or the Special Servicer, as the case
may be, take any action or omit to take any action in accordance with the terms of any Co-Lender Agreement, that would cause the
Master Servicer or the Special Servicer, as applicable, to violate the Servicing Standard or REMIC Provisions;

 

(iv)        any provisions required to be included herein pursuant to the related Co-Lender Agreement are deemed included and shall
be enforceable to the same extent as if set forth herein; and

 

(v)         the Other Master Servicer, the Other Special Servicer, the Other Trustee and the Other Securitization Trust shall be third
party beneficiaries of this Section 3.01(k).

 

Section 3.02    Liability of the Master Servicer. Notwithstanding any Sub-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 for the servicing and administering of the Mortgage Loans (other than with respect to the primary servicing
of any Non-Serviced Mortgage Loans) and the Serviced Companion Loans in accordance with the provisions of this Agreement without
diminution of such obligation or liability by virtue of such

 

    	-138-

    	 

    

 

Sub-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 were servicing and administering the Mortgage Loans (other than with respect to the primary servicing
of any Non-Serviced Mortgage Loans) and the Serviced Companion Loans. 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 non-Specially Serviced Loans) or the Special Servicer (with respect to Specially
Serviced Loans), as applicable, shall use commercially reasonable efforts in accordance with the Servicing Standard to collect
all payments called for under the terms and provisions of the Mortgage Loans (excluding any Non-Serviced Mortgage Loan) (and the
Serviced Companion Loans) it is obligated to service hereunder (including Special Servicing Fees (in the case of the Special
Servicer only), Workout Fees, Liquidation Fees (in the case of the Special Servicer only) and any other fees payable to the Master
Servicer or the Special Servicer if and to the extent the related Mortgage Loan Documents require the related Mortgagor to pay
such fees), and shall follow the Servicing Standard with respect to such collection procedures. For clarification, no obligation
of the Master Servicer or the Special Servicer to use commercially 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 3.06A as applicable, 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 Mortgage Loans
(other than any Non-Serviced Mortgage Loan) other than Specially Serviced Loans, and Special Servicer, with respect to the Specially
Serviced Loans, shall use its reasonable efforts to collect operating statements, rent rolls and other reporting information from
Mortgagors (as required under the related Mortgage Loan Documents); provided, that if the related Mortgage Loan documents permit
the lender to request audited financial statements, the Master Servicer shall be required to request audited financial statements
from the related Mortgagor. Consistent with the foregoing, the Master Servicer (with respect to non-Specially 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 or 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 and the Serviced Companion
Loans as are permitted or required under this Section 3.03.

 

(b)         [Reserved]

 

(c)         The Certificate Administrator shall deliver to the related Other Depositor, the related Other Trustee, the related Other
Certificate Administrator, the related Other Special Servicer, the related Other Master Servicer and the related Other Operating
Advisor (A) promptly following the Closing Date written notice in the form of Exhibit EE attached hereto

 

    	-139-

    	 

    

 

stating
that, as of the Closing Date, the Trust is the holder of such Non-Serviced Mortgage Loan and directing each such recipient to remit
to the Master Servicer all amounts payable to, and to forward, deliver or otherwise make available, as the case may be, to the
Master Servicer all reports, statements, documents, communications and other information that are to be forwarded, delivered or
otherwise made available to, the holder of such Non-Serviced Mortgage Loan under the related Co-Lender Agreement and the applicable
Other Pooling and Servicing Agreement (which notice shall also provide contact information for the Trustee, the Certificate Administrator,
the Master Servicer, the Special Servicer and the party designated to exercise the rights of the “Non-Controlling Note Holder”
under each Co-Lender Agreement), accompanied by a statement that a copy of an executed version of this Agreement is available upon
request, and (B) notice of any subsequent change in the identity of the Master Servicer or the party designated to exercise
the rights of the “Non-Controlling Note Holder” under each Co-Lender Agreement (together with the relevant contact
information). The Master Servicer shall, within two (2) Business Days of receipt of properly identified funds, deposit into the
Collection Account all amounts received with respect to any Non-Serviced Mortgage Loan, the Mortgaged Property related to such
Non-Serviced Mortgage Loan or any related REO Property.

 

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

 

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

 

(a)         With respect to each Mortgaged Property securing a Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole
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 Mortgage Loan (other than
a Non-Serviced Mortgage Loan) or Serviced Whole 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 a Non-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 the case of a Specially Serviced Loan, at the direction of the Special Servicer
will be required to make) a

 

    	-140-

    	 

    

 

payment from amounts on deposit in the Collection Account that would otherwise be a Property Advance
with respect to a Mortgage Loan (other than a Non-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
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 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/or the related Serviced Companion Loan Holder(s) constituted a single lender). 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
Whole Loan 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) and
shall be entitled, “Wells Fargo Bank, National Association, as Master Servicer, on behalf of Wilmington Trust, National Association,
as Trustee for the benefit of the registered Holders of CSAIL 2015-C4 Commercial Mortgage Trust, Commercial Mortgage Pass-Through
Certificates, Series 2015-C4, any related 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 Mortgage Loan Documents and in accordance
with the terms of the related Mortgage Loan or Serviced Whole Loan, as applicable;

 

(ii)         to transfer funds to the Collection Account and/or the applicable Serviced Whole Loan 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
Rate) relating to Escrow Payments, but only from amounts received with respect to the related Mortgage Loan or Serviced Whole Loan,
as applicable, which represent late collections of Escrow Payments thereunder;

  

    	-141-

    	 

    

  

(iii)        for application to the restoration or repair of the related Mortgaged Property in accordance with the related Mortgage Loan
or Serviced Whole Loan, 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 Whole Loan, 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 Mortgage Loan Documents; and

 

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

 

In the event any Mortgage
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 Mortgage Loan Documents permit such discretion.

 

(c)         [Reserved]

 

(d)         To the extent that (i) an operations and maintenance plan is required to be established and executed pursuant to the
terms of a Mortgage Loan (other than a Non-Serviced Mortgage Loan) or a Serviced Whole Loan, or (ii) any repairs, capital
improvements, actions or remediations are required to have been taken or completed pursuant to the terms of the Mortgage Loan (other
than a Non-Serviced Mortgage Loan) or Serviced Whole 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 Mortgage 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 Whole Loan as of the date required under the related Mortgage
Loan or Serviced Whole Loan and report any such failure to the Special Servicer, the 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.

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

accordance with the related Mortgage Loan Documents, in each case to the extent not permitted to be retained by the Master Servicer

(vii)            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 of this Agreement.

 

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 and
defeasance fees 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 and/or defeasance fees 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 and/or defeasance fees 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

 

    	-143-

    	 

    

 

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 Penalty Charges or Modification Fees received by the Master Servicer or the Special
Servicer, as applicable, with respect to any Mortgage Loan into the Collection Account and shall instead apply such fees in accordance
with Section 3.14 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, the Trustee 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 (vii) above with respect to a Mortgage Loan (other than a
Mortgage Loan related to a Serviced Whole Loan), the Special Servicer shall promptly, but in no event later than one (1) Business
Day after receipt, 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 Whole Loan) 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 Distribution Account and the Upper-Tier Distribution
Account in the name of the Certificate Administrator, in trust for the benefit of the Certificateholders. Each of the Distribution
Accounts 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 Distribution Account, as set forth in Section 4.01 of this Agreement, shall be deemed
to make the deposits into the Lower-Tier Distribution Account and the Upper-Tier 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 trust for the benefit of the Certificateholders.

 

    	-144-

    	 

    

 

The Excess Liquidation Proceeds Reserve Account 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.
None of the amounts on deposit in Distribution Account, the Excess Liquidation Proceeds Reserve Account or the Interest Reserve
Account may be invested by 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.

 

(d)              
[Reserved]

 

(e)               [Reserved]

 

(f)                Notwithstanding anything to the contrary herein, each Distribution Account, the Excess Liquidation Proceeds Reserve Account
and the Interest Reserve Account may all be sub-accounts of a single Eligible Account. For the avoidance of doubt, the Collection
Account, the Lower-Tier 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 Upper-Tier
Distribution Account (including interest, if any, earned on the investor of funds in such account) will be owned by the Upper-Tier
REMIC for federal income tax purposes.

 

Section 3.05A. Serviced
Whole Loan Custodial Account.

 

(a)  The Master
Servicer shall establish and maintain, with respect to each Serviced Whole Loan, one or more separate accounts, which may be sub-accounts
of a single account (with respect to each Serviced Whole Loan, the “Serviced Whole Loan Custodial Account”)
in which the amounts described in clauses (i) through (vii) 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 Companion Loan Holder, as
their interests may appear; provided that a Serviced Whole Loan Custodial Account may be a sub-account of the Collection
Account or another Serviced Whole Loan Custodial Account (but shall be deemed to be a separate account for purposes of applying
the terms of this Agreement). Each of the Serviced Whole Loan 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 Serviced Whole Loan Custodial Account,
within two (2) Business Days following receipt (or, in the case of payments by the Master Servicer, when otherwise required to
be so deposited under this Agreement) of properly identified funds, the following payments and collections received or made by
it on or with respect to the Serviced Whole Loan:

 

    	-145-

    	 

    

 

(i)              
all payments on account of principal on the related Serviced Whole Loan, including the principal component of Unscheduled
Payments;

 

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

 

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

 

(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 Serviced Whole Loan Custodial Account;

 

(v)              
all Net REO Proceeds withdrawn from an REO Account pursuant to Section 3.16(a) of this Agreement and all Net Insurance
Proceeds, Net Condemnation Proceeds and Net Liquidation Proceeds with respect to the related Serviced Whole Loan;

 

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

 

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

 

(b)              
The foregoing requirements for deposits in each Serviced Whole Loan 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 and defeasance fees need not be deposited in such Serviced Whole Loan 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 and/or defeasance fees received with respect to the Serviced Whole 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 and/or defeasance fees 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 Penalty Charges and
Modification Fees received by the Master Servicer or the Special Servicer, as applicable, with respect to any Serviced Whole Loan
into the related Serviced Whole Loan 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 that the Master Servicer
deposits in a Serviced Whole Loan Custodial

 

    	-146-

    	 

    

 

Account any amount not required to be deposited therein, it may at any time withdraw
such amount from such Serviced Whole Loan Custodial Account, any provision herein to the contrary notwithstanding. The Master Servicer
shall give written notice to the Certificate Administrator, the Trustee, the related Companion Loan Holders and the Special Servicer
of the location and account number of each Serviced Whole Loan Custodial Account and shall notify the Certificate Administrator,
the Trustee, the related Companion Loan Holder and the Special Servicer in writing of any subsequent change thereof. Each Serviced
Whole Loan 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 backed securities of other series and the other accounts of the Master Servicer.

 

(c)              
Upon receipt of any of the amounts described in clauses (i) through (vii) of Section 3.05A(a)
with respect to a Serviced Whole Loan, the Special Servicer shall promptly, but in no event later than one Business Day after receipt,
remit such amounts to the Master Servicer for deposit into the Serviced Whole Loan Custodial Account in accordance with Section 3.05A(a),
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 a Serviced Whole Loan 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 related Serviced Whole Loan Custodial Account, all in accordance with Section 3.17
of this Agreement.

to pay or reimburse the Master Servicer or the Trustee, (A) for Advances made thereby with respect to Mortgage Loans
that are not part of a Serviced Whole Loan (other than Workout-Delayed Reimbursement Amounts) and any related Advance Interest
Amounts (provided that the Trustee shall have priority with respect to such payment or reimbursement of any such Advances
and any related Advance Interest Amounts), the Master Servicer’s right to reimburse any such Person pursuant to this 

 

    	-147-

    	 

    

 

clause (ii)(A) being
limited to late collections of the particular item which was the subject of the related Advance, Penalty Charges, Condemnation
Proceeds, REO Proceeds, Insurance Proceeds and Liquidation Proceeds on or in respect of the particular Mortgage Loan or REO Property
respecting which such Advance was made, if applicable; provided that (x) prior to the time any Advance is reimbursed,
Advance Interest Amounts may be reimbursed solely from Penalty Charges and Modification Fees collected on the related Mortgage
Loan pursuant to Section 3.14 of this Agreement, and (y) at the time any Advance (other than Workout Delayed Reimbursement
Amounts) is reimbursed, Advance Interest Amounts on such reimbursed Advance shall be payable first from Penalty Charges and Modification
Fees collected on the related Mortgage Loan pursuant to Section 3.14 of this Agreement, and, to the extent such Penalty
Charges and Modification Fees are insufficient, then from general collections on deposit in the Collection Account, (B) for

upon a determination by the Master Servicer, the Special Servicer or the Trustee, as applicable, that a Workout-Delayed Reimbursement
Amount is a Nonrecoverable Advance, in the same manner as Nonrecoverable Advances may be reimbursed (provided that with
respect to each Mortgage Loan or REO Property that relates to a Serviced Whole Loan, such Workout-Delayed Reimbursement Amounts
and Advance Interest Amounts thereon shall first be reimbursed pursuant to Section 3.06A(a)(ii) of this Agreement and,
if not reimbursed pursuant thereto, shall be paid from the Collection Account as provided in this clause (ii)(D));

provision of this Agreement pursuant to which such Person is entitled to reimbursement or payment from the Trust Fund, in each
case only to the extent expressly payable or reimbursable under such Section, it being acknowledged that this clause (vi)
shall not be deemed to modify the substance of any such Section, including the provisions of such Section that set forth the extent
to which one of the foregoing Persons is or is not entitled to payment or reimbursement (provided that with respect to each
Mortgage Loan that is part of a Serviced Whole Loan, such expenses shall first be reimbursed pursuant to Section 3.06A(a)(v)
of this Agreement to the extent related to such Serviced Whole Loan and, if not reimbursed pursuant thereto, shall be paid from
the Collection Account as provided in this clause (vi));

 

(vii)            
to transfer to the Certificate Administrator for deposit in one or more separate, non-interest bearing accounts any amount
reasonably determined by the Certificate Administrator to be necessary to pay any applicable federal, state or local taxes imposed

(x)              
to clear and terminate the Collection Account pursuant to Section 9.01 of this Agreement.

 

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 Whole Loan that
represents the related Companion Loan’s allocable share of such cost, expense, indemnity, or Property Advance or Advance
Interest Amount thereon, the Master Servicer shall use efforts consistent with the Servicing Standard to collect such amounts out
of collections on such Companion Loan (or, if and to the extent permitted under the related Co-Lender Agreement, from the related
Companion Loan Holder) and deposit all such amounts

 

    	-150-

    	 

    

 

(collectively, with respect to such Companion Loan, the “Trust Reimbursement
Amount No. 1”) collected from or on behalf of the related 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 applicable Other Master Servicer, the applicable Other Special Servicer, the applicable Other
Certificate Administrator or the applicable Other Trustee, as applicable, by the holders of the related Non-Serviced Mortgage Loan

request for payments contemplated by the preceding sentence.

 

The 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)-(x) above.

 

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 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 or a Responsible Officer of the Trustee or the Certificate Administrator, 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 or the Certificate
Administrator, 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 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.

 

The Master Servicer shall
pay to, subject to Section 3.01(k)(i), the applicable Other Master Servicer, the applicable Other Special Servicer, the
applicable Other Certificate Administrator or the applicable Other Trustee, as applicable, from the Collection Account on the Master
Servicer Remittance Date amounts permitted to be paid to the applicable Other Master Servicer, the applicable Other Special Servicer,
the applicable Other Certificate Administrator or the applicable Other Trustee, as applicable, therefrom based upon an Officer’s
Certificate received from the applicable Other Master Servicer, the applicable Other Special Servicer, the applicable Other Certificate
Administrator or the applicable Other Trustee, as applicable, on the first Business Day following the immediately preceding Determination
Date, describing the item and amount to which the applicable Other Master Servicer, the applicable Other Special Servicer, the
applicable Other Certificate Administrator or the applicable Other Trustee, as applicable, is entitled. The Master Servicer may
rely conclusively on any such certificate and shall have no duty to re-calculate the amounts stated therein.

 

The Trustee, the Certificate
Administrator, the Operating Advisor, 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 investment income), Trustee/Certificate Administrator Fees, Special
Servicing Compensation, Advances, Advance Interest Amounts, 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)), 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 the Lower-Tier Distribution Account, the Interest Reserve
Account and the Excess Liquidation Proceeds Reserve Account any and all amounts received by the Certificate Administrator in accordance
with Section 3.06(a)(i) of this Agreement. 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 to the Certificate Administrator for deposit in the Lower-Tier Distribution Account, the
Interest Reserve Account and the Excess Liquidation Proceeds Reserve Account the amounts required to be deposited therein pursuant
to the provisions of this Agreement (including, without limitation, Section 3.06(a)(i) of this Agreement), 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 e-mail sent to investorreporting@wellsfargo.com (or such alternative e-mail address provided
by the Master Servicer to the Certificate Administrator in writing) and by telephone at telephone number (800) 326-1334 (or such
alternative number 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 from and including the applicable required remittance
date to, but not including, the date until such late payment is received by the Certificate Administrator.

 

Section 3.06A. Permitted
Withdrawals from the Serviced Whole Loan Custodial Account.

 

(a)     
        The Master Servicer may make withdrawals from the Serviced Whole Loan Custodial Account for
each Serviced Whole Loan only as described below (the order set forth below not constituting an order of priority for such
withdrawals), subject to the application of Penalty Charges and Modification Fees in accordance with the related Co-Lender
Agreement and Section 3.14 of this Agreement:

 

(i)               
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 such Serviced Whole Loan, 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

 

    	-152-

    	 

    

 

in such calendar month),
to transfer to the Collection Account all amounts on deposit in the Serviced Whole Loan 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 the date specified in the related Co-Lender Agreement (or
if no date is specified, on the earlier of (1) the Master Servicer Remittance Date or (2) the business day following the
determination date (or any term substantially similar thereto) as defined in the Other Pooling and Servicing Agreement; provided, however,
that in no event may any such determination date occur prior to the sixth day of the month) 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 Whole Loan, if such funds are received after the Determination Date and before the Distribution Date in
any calendar month), to remit to the related Companion Loan Holder all amounts on deposit in the Serviced Whole Loan
Custodial Account payable to such Companion Loan Holder pursuant to the related Co-Lender Agreement with respect to the
related Companion Loan (or any successor REO Companion Loan), exclusive of any applicable Trust Reimbursement Amount;

 

(ii)              
to pay or reimburse the Master Servicer or the Trustee for Advances made thereby with respect to such Serviced Whole Loan
and any related Advance Interest Amounts (provided that the Trustee shall have priority with respect to such payment or
reimbursement of any such Advances and any related Advance Interest Amounts), the Master Servicer’s right to reimburse any
such Person pursuant to this clause (ii) being limited to late collections (including cure payments by related Companion
Loan Holders) of the particular item which was the subject of the related Advance, Penalty Charges, Condemnation Proceeds, REO
Proceeds, Insurance Proceeds and Liquidation Proceeds on or in respect of the particular Serviced Whole Loan or any related REO
Property; provided, however, that if such Advance has become a Workout-Delayed Reimbursement Amount (but not a Nonrecoverable
Advance), then neither such Workout-Delayed Reimbursement Amount nor any related Advance Interest Amounts shall be reimbursed or
paid, as the case may be, out of payments or other collections of interest (other than Penalty Charges) or Yield Maintenance Charges
on or in respect of the related Mortgage Loan (or any successor REO Mortgage Loan) or the related 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
Mortgage Loan (or a successor REO Mortgage Loan), then neither such Advance nor any related Advance Interest Amounts shall be reimbursed
or paid, as the case may be, out of, or otherwise result in a reduction of, amounts otherwise payable to the related Companion
Loan Holder with respect to the related Pari Passu Companion Loan (or any successor REO Companion Loan);

 

(iii)             
to pay on or before each Master Servicer Remittance Date (1) to the Master Servicer (who shall pay the holder of the Excess
Servicing Fee Rights (if any) the portion of the Servicing Fee that represents Excess Servicing Fees in accordance with Section
3.12 of this Agreement) as compensation, the aggregate unpaid Servicing Fee with respect to such Serviced Whole Loan (to the
extent not otherwise required to be applied against Prepayment Interest Shortfalls) in respect of the immediately preceding Interest
Accrual Period, to be paid from interest received on the related Mortgage Loan or

 

    	-153-

    	 

    

 

Companion Loan, as applicable, and to pay from
time to time to the Master Servicer in accordance with Section 3.07(b) any interest or investment income earned on funds
deposited in such Serviced Whole Loan Custodial Account and (2) to the Special Servicer as compensation, any Special Servicing
Compensation and additional servicing compensation payable with respect to such Serviced Whole Loan; provided, however,
that no Servicing Fees or Special Servicing Compensation earned with respect to the related Mortgage Loan (or a successor REO Mortgage
Loan) shall be payable out of, or otherwise result in a reduction of, amounts otherwise payable to the related Companion Loan Holder
with respect to the related Pari Passu Companion Loan (or any successor REO Companion Loan), and no Servicing Fees or Special Servicing
Compensation earned with respect to the related Companion Loan (or any successor REO Companion Loan) shall be payable out of, or
otherwise result in a reduction of, amounts otherwise payable to the Trust with respect to the related Mortgage Loan (or a successor
REO Mortgage Loan) (it being acknowledged and agreed that this proviso is in no way intended to limit the rights of the Master
Servicer or Special Servicer under the related Co-Lender Agreement to seek payment of any unpaid Servicing Fees or Special Servicing
Compensation, as applicable, with respect to any Companion Loan from the related Companion Loan Holder);

 

(iv)            
to pay for costs and expenses incurred by the Trust Fund solely with respect to such Serviced Whole Loan and related REO
Property pursuant to Section 3.10(e) and to pay Liquidation Expenses out of Liquidation Proceeds pursuant to Section
3.11;

 

(v)              
to the extent not reimbursed or paid pursuant to any other clause of this Section 3.06A, to reimburse or pay
the Master Servicer, the Trustee, the Certificate Administrator, the Operating Advisor, the Special Servicer or the Depositor,
as applicable, for unpaid Additional Trust Fund Expenses, Servicing Fees and other unpaid items incurred by or owing to such Person
pursuant to the second sentence of Section 3.07(c), Section 3.08(a), Section 3.08(b), Section 3.10,
the second sentence of Section 3.12(a), the third sentence of Section 3.12(c), Section 3.16(a), Section
3.28(k), Section 6.03, Section 7.04, Section 8.05(a), Section 8.05(b), Section 8.05(d) or
Section 11.07, or any other provision of this Agreement pursuant to which such Person is entitled to reimbursement or payment
from the Trust Fund, in each case only to the extent expressly payable or reimbursable under such Section and to the extent related
to such Serviced Whole Loan and not related to amounts which are solely expenses of the Trust Fund (such as expenses related to
administration of the Trust Fund or REMIC taxes, penalties or interest or preservation of the REMIC status of each Trust REMIC),
it being acknowledged that this clause (v) shall not be deemed to modify the substance of any such Section, including
the provisions of such Section that set forth the extent to which one of the foregoing Persons is or is not entitled to payment
or reimbursement; provided, however, that no payment or reimbursement to the Operating Advisor, or payment of Trustee/Certificate
Administrator Fees, or payment or reimbursement of costs and expenses associated with obtaining a Rating Agency Confirmation, shall
be made out of, or otherwise result in a reduction of, amounts otherwise payable to the related Companion Loan Holder with respect
to the related Pari Passu Companion Loan (or successor REO Companion Loan), and no payment or reimbursement of costs and

 

    	-154-

    	 

    

 

expenses
associated with obtaining a Companion Loan Rating Agency Confirmation shall be made out of, or otherwise result in a reduction
of, amounts otherwise 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 Serviced Whole
Loan Custodial Account as are contemplated by the related Co-Lender Agreement and, to the extent consistent with the related Co-Lender
Agreement, Section 3.14 of this Agreement;

 

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

 

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

 

(ix)             
to clear and terminate such Serviced Whole Loan 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 Serviced Whole Loan 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 Whole Loan 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, the Master Servicer (with respect to Non-Specially Serviced
Loans) and the Special Servicer (with respect to Specially Serviced Loans) shall use efforts consistent with the Servicing Standard
to collect such amounts disproportionately borne by the Trust out of collections on such Companion Loan (or, if and to the extent
permitted under the related Co-Lender Agreement, from the related Companion Loan Holder) and deposit all such amounts (collectively,
with respect to such 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 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 Serviced Whole Loan Custodial Account, amounts

 

    	-155-

    	 

    

 

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 Serviced Whole Loan Custodial Account, on a loan-by-loan basis.

 

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 Serviced Whole Loan 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 Serviced Whole Loan 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,
that for the avoidance of doubt, neither the Trustee/Certificate Administrator Fee nor the Operating Advisor Fee shall be paid
from funds on deposit in a Serviced Whole Loan 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 Whole Loan, 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 Serviced Whole Loan 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 the date specified in the related Co-Lender Agreement (or if
no date is specified, on the earlier of (1) the Master Servicer Remittance Date or (2) the business day following the determination
date (or any term substantially similar thereto) as defined in the Other Pooling and Servicing Agreement; provided, however,
that in no event may any such determination date occur prior to the sixth day of the month) 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 Whole Loan, 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 Companion Loan Holder all amounts on deposit in a Serviced Whole Loan Custodial
Account payable to such

 

    	-156-

    	 

    

 

Companion Loan Holder pursuant to the related Co-Lender Agreement with respect to the related 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 Distribution Account
on such Master Servicer Remittance Date.

 

Section 3.07         
Investment of Funds in the Collection Account, the REO Account, the Interest Reserve Account, the Mortgagor Accounts,
the Excess Liquidation Proceeds Reserve Account and Other Accounts.

 

(a)              
The Master Servicer (or with respect to any REO Account, the Special Servicer, or, with respect to each Distribution Account,
the Excess Liquidation Proceeds Reserve Account and the Interest Reserve Account (the foregoing accounts, the “Certificate
Administrator Accounts”), the Certificate Administrator) may direct any depository institution maintaining the Collection
Account, any Serviced Whole Loan Custodial Account, any Mortgagor Accounts (subject to the second succeeding sentence), the Certificate
Administrator Accounts and the REO Accounts (each of the Collection Account, any Serviced Whole Loan Custodial Account, any REO
Account, any Mortgagor Account and any Certificate Administrator 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; provided that any amounts invested
by the Certificate Administrator in Permitted Investments managed or advised by the Certificate Administrator or its Affiliates
shall mature on or prior to the Distribution Date in time to be available to make timely distributions to Certificateholders. 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 Reserve Account, Escrow Account or Lockbox 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 Whole Loan) 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 Certificate Administrator (on behalf of the Trustee
for the benefit of the Certificateholders) or in the name of a nominee of the Certificate Administrator. The Certificate Administrator
shall have sole control (except with respect to investment direction which shall be in the control of the Master Servicer (or the
Special Servicer, with respect to any REO Accounts or the Certificate Administrator with respect to the Certificate Administrator
Accounts) as an independent contractor to the Trust Fund) over each such investment and any certificate or other instrument
evidencing any such investment shall be delivered directly to the Certificate Administrator or its agent (which shall initially
be the Master Servicer), together with any document of transfer, if any, necessary to transfer title to such investment to the
Certificate Administrator or its nominee. The Certificate Administrator shall have no responsibility or liability with respect
to the

 

    	-157-

    	 

    

 

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 Certificate Administrator, 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 Certificate Administrator, 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 Investment payable on demand, the Master Servicer (or the Special Servicer in the
case of REO Accounts, or the Certificate Administrator, in the case of the Certificate Administrator Accounts), 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) that such Permitted Investment would not constitute
a Permitted Investment in respect of funds thereafter on deposit in the related Investment Account.

 

(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 Whole Loan) or applicable law to be for the benefit of the related Mortgagor, (ii) any
REO Account, which shall be for the benefit of the Special Servicer or (iii) the Certificate Administrator Accounts, which
shall be for the benefit of the Certificate Administrator, and, if held in the Collection Account or REO Account shall be subject
to withdrawal by the Master Servicer or the Special Servicer, as applicable, in accordance with Section 3.06 or Section
3.16(a) of this Agreement, as applicable. The Master Servicer (or with respect to any REO Account, the Special Servicer and
with respect to the Certificate Administrator Accounts, the Certificate Administrator) 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 Mortgage Loan Documents to direct such investment in such Mortgagor Account); provided, however, that
the Certificate Administrator, 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 Whole Loan)
or applicable law, provided that, notwithstanding the foregoing, none of the Master Servicer, the Special Servicer or the
Certificate Administrator (in their respective capacities as Master Servicer, Special Servicer and Certificate Administrator, 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

 

    	-158-

    	 

    

 

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, 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 any Non-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(s) 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
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 and (i) with the consent of the Controlling Class Representative (unless a Control Termination Event has
occurred and is continuing) or (ii) if a Control Termination Event has occurred and is continuing, following consultation with
the Controlling Class Representative (unless a Consultation Termination Event has occurred and is continuing), shall cause to be
maintained for each REO Property no less insurance coverage than was previously required of the Mortgagor under the related Mortgage
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 Mortgage Loan Documents require the related Mortgagor to maintain insurance with

 

    	-159-

    	 

    

 

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 Mortgage 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 Mortgage Loan Documents) shall be deposited into the Collection Account
pursuant to Section 3.05 of this Agreement or the Serviced Whole Loan 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 Mortgage
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 Mortgaged Property (other than an REO Property and other than with respect to a Non-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 Mortgage Loan or Serviced Whole 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 Companion Loan and (ii) the
maximum amount of such insurance required by the terms of the related Mortgage Loan or Serviced Whole Loan 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 Mortgage Loan (other
than a Non-Serviced Mortgage Loan) or Serviced Whole Loan pursuant to which earthquake insurance is required to be maintained pursuant
to the terms of the Mortgage Loan or Serviced Whole Loan, 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 Whole Loan or, if not specified, in-place at origination. If an REO Property (i) is located in a federally designated
special flood hazard area or (ii) is related to a Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole
Loan with respect to which earthquake insurance would be appropriate in accordance with the Servicing Standard and such

 

    	-160-

    	 

    

 

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 the REO Mortgage Loans) agrees to prepare and present, on behalf of itself, the Trustee and the Certificateholders and
the 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 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 Mortgage
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 Mortgage Loan Documents if the originator of the Mortgage Loan or Serviced Whole Loan 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 Mortgage 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, shall 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

 

    	-161-

    	 

    

 

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 with respect to the
Mortgaged Properties that secure any Non-Serviced Mortgage Loan) as to which the related Mortgagor has not maintained insurance
required by the related Mortgage Loan or, if applicable, related Serviced Whole Loan (other than any Mortgagor that is required
under the related Mortgage 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 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 any Non-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 Serviced Whole
Loan 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 Whole Loan, 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 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 with respect to the
Mortgaged Property that secures a Non-Serviced Mortgage Loan) or the Special Servicer causes any REO Property (other than an REO
Property acquired in respect of a Non-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)

 

    	-162-

    	 

    

 

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 Serviced Whole Loan 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 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” 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 maintain a fidelity bond in such form as is consistent with the
Servicing Standard and in such amounts that are consistent with the Servicing Standard. 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 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 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, respectively,
the Master Servicer or the Special Servicer 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 for it to maintain or cause to be maintained by an agent or
contractor servicing any Mortgage Loan or Serviced Whole Loan 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.

Enforcement of Due-On-Sale and Due-On-Encumbrance Clauses; Assumption Agreements; Defeasance Provisions.

 

(a)              
Upon receipt of any request of a waiver or a consent in respect of a due-on-sale or due-on-encumbrance provision, the Master
Servicer (with respect to non-Specially Serviced Loans and subject to the consent of the Special Servicer) and the Special Servicer
(with respect to Specially Serviced Loans) shall (i) promptly analyze such consent, waiver or reasonable request (and in the case
of the Master Servicer to the extent it is recommending approval, prepare a written recommendation and analysis with all information
reasonably available to the Master Servicer that the Special Servicer may reasonably request in order to withhold or grant its
consent), and (ii) close the related transaction and, subject to the consultation and/or consent rights (if any) of the Controlling
Class Representative or the consultation rights of any related 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 Section 3.09(b), 3.21, 3.24, 3.25 and Section 3.27; provided, however,
that the Master Servicer or the Special Servicer, as applicable, shall not 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 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 (i) non-Specially
Serviced Loans, the Master Servicer (subject to the Special Servicer’s consent) or (ii) with respect to Specially Serviced
Loans, the Special Servicer, 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 Mortgage on transfers
or further encumbrances of the related Mortgaged Property and on transfers or further encumbrances of interests in the related
Mortgagor, unless following its receipt of a request of a consent or waiver in respect of a due-on-sale or due-on-encumbrance provision,
the Master Servicer (with the written consent of the Special Servicer, which consent shall be deemed given if not denied within
15 Business Days (or such other time as required by any 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 Companion Loan Holder) 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 in the preceding paragraph)
or the Special Servicer, as applicable, has made any such determination, the Special Servicer or the Master Servicer, as applicable,
shall 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 11.13 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 the Special Servicer
is granting consent to an assumption pursuant to Section 3.09(a) in

 

    	-164-

    	 

    

 

accordance with the terms of the Mortgage Loan Documents
and there is no material waiver of any conditions or any other provisions of the Mortgage Loan Documents, with respect to all Serviced
Mortgage Loans and Whole Loans, the Special Servicer shall, prior to taking such an action or consenting to the Master Servicer’s
taking of such an action, (A) obtain the written consent of the Controlling Class Representative (unless a Control Termination
Event has occurred and is continuing) or (B) if a Control Termination Event has occurred and is continuing, consult with the Controlling
Class Representative (unless a Consultation Termination Event has occurred and is continuing), which consent shall be deemed given
ten (10) Business Days after receipt (unless earlier objected to) by the Controlling Class Representative of the written recommendation
of the Master Servicer or the Special Servicer, as applicable, for such action and any additional information the Controlling Class
Representative may reasonably request for the analysis of such request, which recommendation and information may be delivered in
an electronic format reasonably acceptable to Controlling Class Representative and the Master Servicer or the Special Servicer,
as applicable. In addition, the Special Servicer or the Master Servicer, as applicable, may not waive the rights of the lender
or grant its consent under any “due-on-encumbrance” provision unless (1) the Special Servicer or the Master Servicer,
as applicable, shall have received a prior written Rating Agency Confirmation with respect to such action or (2) the related
Mortgage Loan (including a Mortgage Loan related to a Serviced Whole Loan) (A) represents less than 2% 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 $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
Mortgage Loan or Serviced Whole Loan, as applicable, and the principal balance of the proposed additional lien) and (E) is
not one of the 10 largest Mortgage Loans (considering any Crossed Mortgage Loan Group as a single Mortgage Loan) in the Mortgage
Pool based on principal balance (although no such Rating Agency Confirmation will be required if such Mortgage Loan has a principal
balance less than $10,000,000). Further, the Special Servicer or the Master Servicer, as applicable, may not waive the rights of
the lender or grant its consent under any “due-on-sale” provision unless the Special Servicer or the Master Servicer,
as applicable, shall have received a prior written Rating Agency Confirmation with respect to such action unless the related Mortgage
Loan (including a Mortgage Loan related to a Serviced Whole Loan) (A) represents less than 5% 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 Crossed Mortgage Loan Group as a single Mortgage Loan) in the Mortgage
Pool based on principal balance (although no such Rating Agency Confirmation will be required if such Mortgage Loan has a principal
balance less than $10,000,000). For the purposes of this Agreement, due-on-sale provisions shall include, without limitation, any
rights arising out of 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, to the extent prohibited under the related Mortgage Loan Documents,
and due on encumbrance provisions shall include, without limitation, any rights arising out of 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, to the extent
prohibited under the related Mortgage Loan Documents.

 

The Special Servicer
or the Master Servicer, as applicable, shall notify in writing the other party, the Trustee, the Certificate Administrator, the
Rule 17g-5 Information Provider

 

    	-165-

    	 

    

 

(for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section
11.13 of this Agreement), the Operating Advisor (only after the occurrence and during the continuance of a Control Termination
Event) and, with respect to a Serviced Whole Loan, the related 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.

 

In connection with any
request for a Rating Agency Confirmation from a Rating Agency pursuant to this Section 3.09(a), the Special Servicer or
the Master Servicer, as applicable, 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 11.13 of this Agreement.

 

Further, subject to the
terms of the related Mortgage Loan Documents and applicable law, the Special Servicer or the Master Servicer, as applicable, shall
use reasonable efforts to ensure that all costs in connection with any assumption or encumbrance, including any arising from seeking
a Rating Agency Confirmation, are 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).

 

To the extent not prohibited
by the applicable Mortgage Loan Documents and applicable law, the Special Servicer or the Master 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 Companion Loan or the related Note(s), other than pursuant to Section 3.24 of this Agreement.

 

(d)              
With respect to any Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan which permits release
of Mortgaged Properties through defeasance and to the extent consistent with the terms of the related Mortgage Loan Documents:

 

(i)               
Subject to the consent rights and process set forth in Section 6.09 with respect to Major Decisions, the Master Servicer
shall process all defeasances of Mortgage Loans (other than any Non-Serviced Mortgage Loan) and Serviced Companion Loans in accordance
with the terms of the related Mortgage Loan Documents, and shall be entitled

 

    	-166-

    	 

    

 

to any defeasance fees paid relating thereto (provided
that for the avoidance of doubt, any such defeasance fee shall not include any Modification Fees or waiver fees in connection
with a defeasance to which the Special Servicer is entitled to under this Agreement).

 

(ii)              
In the event such Mortgage Loan or Serviced Whole Loan 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,
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 Mortgage Loan Documents), purchase or cause the purchase of such obligations in accordance with the terms of
such Mortgage Loan or Serviced Whole Loan 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 Companion Loan Holder; provided
that, subject to the related Mortgage 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 current guidelines
of the Rating Agencies. Notwithstanding the foregoing, with respect to certain Mortgage Loans originated or acquired by Column,
MC-Five Mile, BSPCC, Bancorp and WDCPF I CS that are subject to defeasance, (i) each of Column, MC-Five Mile, BSPCC, Bancorp and
WDCPF I CS has retained on behalf of itself or its affiliate the right, if any, to establish or designate the successor borrower
and (ii) each of Column, MC-Five Mile, BSPCC and WDCPF I CS has retained on behalf of itself or its affiliate the right, if any,
to purchase or cause to be purchased the related defeasance collateral (collectively, the “Loan Seller 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 Loan Seller Defeasance Rights and Obligations in the related Mortgage Loan Documents, the Master Servicer
shall provide, within five (5) business days of receipt of such notice, written notice of such defeasance request to Column, MC-Five
Mile, BSPCC, Bancorp and WDCPF I CS, as applicable, in the case of the Mortgage Loans for which Column, MC-Five Mile, BSPCC, Bancorp
and WDCPF I CS, as applicable is the related Mortgage Loan Seller. Until such time as Column, MC-Five Mile, BSPCC, Bancorp and
WDCPF I CS, as applicable, provides written notice to the contrary, notice of a defeasance of a Mortgage Loan with Loan Seller
Defeasance Rights and Obligations shall be delivered to Column, MC-Five Mile, BSPCC, Bancorp and WDCPF I CS, as applicable, pursuant
to the notice provisions hereof.

 

(iii)             
The Master Servicer shall require, to the extent the Mortgage 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
Mortgage 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, or any other securities that comply with Treasury Regulations

 

    	-167-

    	 

    

 

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 Mortgage 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 Mortgage Loan Documents)
from an Independent certified public accountant certifying that the “government securities” within the meaning of Section 2(a)(16)
of the Investment Company Act, 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 Mortgage 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 each 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 Whole Loan 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 Mortgage 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 Whole Loan. In
the event that the Mortgagor is not required to pay any such costs and expenses under the terms of the Mortgage 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

 

    	-168-

    	 

    

 

(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
Mortgage Loan Documents).

 

(ix)           
The Master Servicer may accept as defeasance collateral of any “government security,” within the meaning of
Treasury Regulation’s Section 1.860G-(2)(a)(8)(ii), notwithstanding any more restrictive requirements in the Mortgage
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 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 Section 3.09, without any other approval or consent, the Master Servicer
(for Mortgage Loans and Serviced Whole Loans other than Specially Serviced Loans) or the Special Servicer (for Specially Serviced
Loans) may grant and process a Mortgagor’s request for (i) consent to subject the related Mortgaged Property to an immaterial
easement, a right of way or similar agreement for utilities, access, parking, public improvements or another purpose, (ii) consent
to subordination of the related Mortgage Loan or Serviced Whole Loan to such easement, right of way or similar agreement and (iii) consent
to any other matter that is not a Major Decision, is not a waiver of a due-on-sale or due-on-encumbrance clause and (with respect
to the Master Servicer) does not otherwise require the Special Servicer’s consent; provided that the Master Servicer
or Special Servicer, as applicable, (a) shall have determined in accordance with the Servicing Standard that such easement,
right of way or similar agreement or other matter will not materially and adversely affect the operation or value of such Mortgaged
Property or the Trust Fund’s interest in the Mortgaged Property and (b) shall have determined that such easement, right
of way or similar agreement or other matter 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 (b) above.

Promptly upon the occurrence of an Appraisal Reduction Event (other than with respect to a Non-Serviced Mortgage Loan),
the Special Servicer shall use reasonable efforts to obtain an updated Appraisal of the Mortgaged Property or REO Property, as
the case may be, the costs of which shall be advanced by, and reimbursable to the Master Servicer, 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); 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 Mortgage Loans 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

 

    	-169-

    	 

    

 

determine the Appraisal Reduction Amount
with respect to a Serviced Whole Loan shall be delivered by the Special Servicer, upon request, to each related Companion Loan
Holder.

 

The Certificate Principal
Balance of each of the 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) 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 Principal Balances of the following
Classes of Certificates in the following order of priority: first, to the Class NR Certificates; second, to the Class G
Certificates; third, to the Class F Certificates; fourth, to the Class E Certificates; fifth, to
the Class D Certificates; sixth, to the Class C Certificates; seventh, to the Class B Certificates; eighth,
to the Class A-S Certificates; and finally, pro rata 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-SB Certificates, based
on their respective Certificate Principal Balances (provided in each case that no Certificate Principal Balance in respect of any
such Class may be notionally reduced below zero). With respect to any Appraisal Reduction Amount calculated for the purposes of
determining the Non-Reduced Certificates or the Controlling Class, as well as the occurrence of a Control Termination Event, the
appraised value of the related Mortgaged Property shall be determined on an “as-is” basis.

 

The Special Servicer
shall promptly notify the Certificate Administrator and Master Servicer in writing of the determination of any such Appraisal Reduction
Amount, and the Certificate Administrator upon receipt of such notice shall promptly post notice of such determination of any such
Appraisal Reduction Amount to the Certificate Administrator’s website.

 

Any Appraisal Reduction
Amounts with respect to a Serviced Whole Loan shall be allocated to the related Mortgage Loan and each related Serviced Companion
Loan on a pro rata and pari passu basis in accordance with the respective outstanding principal balances of such
related Mortgage Loan and the related Serviced Companion Loan(s).

 

The Holders of Certificates
representing the majority of the Certificate Principal Balance of any Class of Control Eligible Certificates that is or would be
determined to no longer be the Controlling Class (such Class, an “Appraised-Out Class”) as a result of an allocation
of an Appraisal Reduction Amount in respect of such Class shall have the right to challenge the Special Servicer’s Appraisal
Reduction Amount determination and, at their sole expense, obtain a second Appraisal of any Mortgage Loan for which an Appraisal
Reduction Event has occurred (such Holders, the “Requesting Holders”). The Requesting Holders shall cause the
Appraisal to be prepared on an “as-is” basis by an MAI Appraiser in accordance with Uniform Standards of Professional
Appraisal Practice (as confirmed by the Special Servicer), and the Appraisal scope and analysis (but not the valuation) shall 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 Amount determination
within 10 days of the Requesting Holders’ receipt of written notice of the determination of such Appraisal Reduction
Amount.

 

    	-170-

    	 

    

 

In addition to the foregoing,
the Holders of Certificates representing the majority of the Certificate Principal 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 Mortgage Loan for which
an Appraisal Reduction Event has occurred if an event has occurred at or with regard to the related Mortgaged Property or Mortgaged
Properties (including, without limitation, a material change in market values) that would have a material effect on its Appraised
Value, and the Special Servicer shall use its reasonable efforts to ensure that such Appraisal is delivered within 30 days
from receipt of such Person’s written request and shall ensure that such Appraisal is prepared on an “as-is”
basis; 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
(including, without limitation, a material change in market values) 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,
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 is warranted and, if so warranted, shall recalculate such Appraisal
Reduction Amount based upon such additional Appraisal. If required by any such recalculation, the Appraised-Out Class shall be
reinstated as 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 Mortgage 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 or Special 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, if available, or any other liable party if the laws of the

 

    	-171-

    	 

    

 

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 Officers’ Certificate delivered to the Trustee,
the Certificate Administrator, the Controlling Class Representative (prior to the occurrence and continuance of a Consultation
Termination Event) and any related Companion Loan Holder; provided that to the extent the related Serviced Companion Loan
has been included in a securitization transaction, all notices and documentation required to be provided to the related Serviced
Companion Loan Holder shall be provided to the Other Master Servicer under such securitization transaction.

 

In the event that title
to any Mortgaged Property 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 pursuant to the terms of this Agreement) 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, the related Serviced Companion Loan Holders. Notwithstanding any such acquisition of title
and cancellation of the related Mortgage Loan or Serviced Whole Loan, such 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 and shall be reduced only by collections net of expenses.

 

(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 a Trust REMIC to fail to qualify as a REMIC 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 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

 

    	-172-

    	 

    

 

either Trust REMIC to fail to qualify
as a REMIC 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, or 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 or the Certificateholders or, if applicable,
the related 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 federal 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, if applicable, any related Serviced Companion
Loan Holder (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, if applicable, any related Serviced Companion Loan Holder(s) (as a collective whole as if the Trust Fund and, if applicable,
the related Serviced Companion Loan Holder(s) constituted a single lender 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 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 Companion Loan Holder,
the Special Servicer may,

 

    	-173-

    	 

    

 

in its discretion, establish a single member limited liability company with the Trust Fund and, if applicable,
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 or Special 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 Certificateholder of any Regular Certificates and any related Companion
Loan Holder upon written request to the Special Servicer.

 

(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
Companion Loan Holder(s), as a collective whole as if the Trust Fund and any related Companion Loan Holder constituted a single
lender, 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 Companion Loan Holder(s),
as a collective whole as if the Trust Fund and any related Companion Loan Holder(s) constituted a single lender, 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, the Special Servicer shall take such action as it deems to be in the best economic interest of the Trust
Fund and any related Companion Loan Holder(s), as a collective whole as if the Trust Fund and any related Companion Loan Holder(s)
constituted a single lender. 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

 

    	-174-

    	 

    

 

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 Companion Loan Holder.

 

Section 3.11         
Trustee and Certificate Administrator to Cooperate; Release of Mortgage Files. Upon the payment in full of any Mortgage
Loan or Serviced Whole Loan 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 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.

 

From time to time upon
request of the Master Servicer or Special Servicer and delivery to the Custodian of a Request for Release, the Certificate Administrator
shall promptly cause the Custodian to 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 Custodian, or in the event of a
liquidation or conversion of the Mortgage Loan or Serviced Whole Loan 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 Whole Loan was liquidated and
that all amounts received or to be received in connection with such liquidation which are required to be deposited into the Collection
Account have been so deposited, or that such Mortgage Loan or Serviced Whole Loan has become an REO Property, the Custodian shall
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 Whole Loan, or to obtain
a deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage 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 Other Pooling and Servicing Agreement related to a Non-Serviced
Mortgage Loan, and as appropriate for enforcing the terms of, or otherwise properly servicing, such Non-Serviced Mortgage Loan,
the applicable Other Master Servicer, the applicable Other Special

 

    	-175-

    	 

    

 

Servicer or other similar party requests delivery to it of the
original Note(s) for such Non-Serviced Mortgage Loan, then such party shall deliver a Request for Release in the form of Exhibit C
attached hereto to the Custodian, and the Custodian shall release or cause the release of such original Note(s) to the requesting
party or its designee. In connection with the release of the original Note(s) for a Non-Serviced Mortgage Loan in accordance with
the preceding sentence, the Custodian shall obtain such documentation as is appropriate to evidence the holding by the applicable
Other Master Servicer, the applicable Other Special Servicer or such other similar party, as the case may be, of such original
Note(s) as custodian on behalf of and for the benefit of the Trustee.

(a)

(i) 100% of any Excess Modification Fees with respect to a modification, waiver, extension or amendment of a non-Specially
Serviced Mortgage Loan agreed to by the Master Servicer pursuant to Section 3.24 of this Agreement that did not

3.24 of this Agreement), (iii) 100% of any defeasance fee received in connection with a defeasance of a Serviced Loan

defeasance fee shall not include any Modification Fees or waiver fees in connection with a defeasance to which the Special Servicer
is entitled under this Agreement), (iv) 100% of any Assumption Fees with respect to a non-Specially Serviced Mortgage Loan consented

Loan is a Specially Serviced Loan, and (xi) 100% of fees for insufficient or returned checks actually received from Mortgagors
on all Mortgage Loans (other than a Non-Serviced Mortgage Loan) and Serviced Companion Loans; provided, however,
that the Master Servicer

 

    	-176-

    	 

    

 

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 Whole Loan, 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 Whole Loan, 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 Section 3.06(a)(iii), 3.06A and 3.07(b), to withdraw from the Collection Account and the Serviced Whole
Loan Custodial Accounts and to receive from any Mortgagor Accounts (to the extent not payable to the related Mortgagor under a
Mortgage Loan or Serviced Whole Loan or applicable law) any interest or other income earned on deposits therein. Interest or other
income earned on funds in the Collection Account, Serviced Whole Loan Custodial Account and Mortgagor Accounts (to the extent consistent
with the related Mortgage 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. For the avoidance of doubt, with respect
to any fee 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, 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.

 

Wells Fargo Bank, National
Association and any successor holder of the Excess Servicing Fee Rights shall be entitled, at any time, at its own expense, to
transfer, sell, pledge or otherwise assign such Excess Servicing Fee Rights in whole (but not in part), in either case, to any
Qualified Institutional Buyer or Institutional Accredited Investor (other than a Plan); provided that no such transfer,
sale, pledge or other assignment shall be made unless (i) that transfer, sale, pledge or other assignment is exempt from the registration
and/or qualification requirements of the Securities Act and any applicable state securities laws and is otherwise made in accordance
with the Securities Act and such state securities laws, (ii) the prospective transferor shall have delivered to the Depositor a
certificate substantially in the form attached as Exhibit CC-1 to this Agreement, and (iii) the prospective transferee
shall have delivered to Wells Fargo Bank, National Association and the Depositor a certificate substantially in the form attached

or any other securities law or to take any action not otherwise required under this Agreement to permit the transfer, sale, pledge
or assignment of an Excess Servicing Fee Right without registration or qualification. Wells

Fargo Bank, National Association and
each holder of an Excess Servicing Fee Right desiring to effect a transfer, sale, pledge or other assignment of such Excess Servicing
Fee Right shall, and Wells Fargo 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
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 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.

 

Notwithstanding anything
herein to the contrary, in the case of a Serviced Whole Loan, 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 Companion Loan(s),
and in no event shall Servicing Fees with respect to the related 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. 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 Pari Passu Companion Loan from the related Companion Loan Holder.

 

Notwithstanding anything
herein to the contrary, the Master Servicer and the Special Servicer shall each be entitled to charge reasonable review fees in
connection with any Mortgagor request.

(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 in an amount equal to $210 per month.
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 Companion Loan that is included as part of each Serviced Whole Loan) and 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
Whole Loan or portion thereof, the related Serviced Whole Loan Custodial Account as set forth in Section 3.06(a)(iv) and
Section 3.06(a)(vi) and 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. The Special Servicer shall not be entitled to any Special Servicing Fee with respect to any Non-Serviced
Mortgage Loan. In addition, the Special Servicer shall be entitled to receive, as additional servicing compensation, (i) 50%
of any Excess Modification Fees with respect to a modification, waiver, extension or amendment of a non-Specially Serviced Loan
and/or any Serviced Companion Loan consented to by the Special Servicer pursuant to Section 3.24 of this Agreement, (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 non-Specially Serviced Loan and/or any Serviced
Companion Loan consented to by the Special Servicer, (v) 100% of Ancillary Fees (other than fees for insufficient or returned
checks) and assumption application fees actually received from Mortgagors on Specially Serviced Loans, (vi) 100% of Consent
Fees with respect to a Specially Serviced Loan, (vii) 50% of any Consent Fees with respect to a non-Specially Serviced Loan and/or
any Serviced Companion Loan consented to by the Special Servicer, (viii) 100% of Excess Penalty Charges paid by the Mortgagors
with respect to any Mortgage Loan (other than a Non-Serviced Mortgage Loan) and/or Serviced Whole Loan accrued during the period
any such Mortgage Loan is a Specially Serviced Loan and (ix) any interest or other income earned on deposits in the REO Accounts
for any REO Mortgage Loan (other than any Non-Serviced Mortgage Loan). The Special Servicer shall not be entitled to any Special
Servicing Fees, Liquidation Fees or Workout Fees, with respect to any Non-Serviced Mortgage Loan. For the avoidance of doubt, with
respect to any fee 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, 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

 

    	-179-

    	 

    

 

(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.

 

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

 

The Special Servicer
shall also be entitled to additional servicing compensation in the form of a Workout Fee with respect to each Corrected Mortgage
Loan at the Workout Fee Rate on such Mortgage Loan or Serviced Whole Loan for so long as it remains a Corrected Mortgage Loan.
The Special Servicer shall not be entitled to any Workout Fee with respect to any Non-Serviced Mortgage Loan. The Workout Fee with
respect to any Corrected Mortgage 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 Mortgage Loan. If
the Special Servicer is terminated (other than for cause) or resigns it shall retain the right to receive any and all Workout Fees
payable in respect of Mortgage Loans or Serviced Whole Loans (1) that became Corrected Mortgage 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 Whole Loan
subsequently becomes a Specially Serviced Loan); and (2) 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 Mortgage Loan solely
because the Mortgagor had not had sufficient time to make three consecutive timely Monthly Payments and which subsequently becomes
a Corrected Mortgage Loan as a result of the Mortgagor making such three consecutive timely Monthly Payments. 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 any Non-Serviced Mortgage Loan)
payable out of the Liquidation Proceeds prior to the deposit of the Net Liquidation Proceeds in the Collection Account or the Serviced
Whole Loan Custodial Account, as applicable. However, no Liquidation Fee will be payable 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 only be entitled to receive a Liquidation Fee or a Workout Fee, but not both,
with respect to any specific collections or proceeds on any Mortgage Loan or Serviced Whole Loan. 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 Whole Loan 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
Mortgage Loan Documents, including exercising all remedies available under such Mortgage Loan Documents that would be in accordance
with the Servicing Standard, specifically

 

    	-180-

    	 

    

 

taking into account the costs or likelihood of success of any such collection efforts
and the Realized Loss 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 Non-Serviced Mortgage Loan or any Non-Serviced Companion Loan.

 

Notwithstanding anything
herein to the contrary, in the case of a Serviced Whole Loan, 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 Pari Passu Companion Loan, and in no event shall Special Servicing Compensation with respect to the related Pari Passu
Companion Loan (including an REO Companion Loan) be payable out of payments and other collections with respect to 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 Companion Loan from the related Companion
Loan Holder.

 

Notwithstanding anything
herein to the contrary, the Master Servicer and the Special Servicer shall each be entitled to charge reasonable review fees in
connection with any Mortgagor request.

 

(d)              
The Master Servicer, the 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, the 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 Whole Loan, (to the extent recovery is permitted
from a Serviced Whole Loan 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, as determined by the Master

 

    	-181-

    	 

    

 

Servicer or the Special
Servicer in accordance with the Servicing Standard or by the Operating Advisor in its commercially reasonable judgment or the Certificate
Administrator’s or the Trustee’s in its 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 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,
without charge, and within 2 Business Days following the related Determination Date, and the Master Servicer shall deliver to the
Certificate Administrator, if and to the extent received thereby, without charge on the same day as the Master Servicer is required
to deliver the CREFC® Investor Reporting Package for such Collection Period, 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 Mortgage Loan or Companion Loan and any purchaser
of any Mortgage Loan, Companion Loan or REO Property) in connection with the disposition, workout or foreclosure of any Mortgage
Loan or Serviced Whole 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. For the avoidance of doubt, the Special Servicer is entitled to receive
any Permitted Special Servicer/Affiliated Fees under this Agreement.

 

Section 3.13         
Compensating Interest Payments. The Master Servicer shall deliver to the Certificate Administrator for deposit in
the Lower-Tier Distribution Account on each Master Servicer Remittance Date, without any right of reimbursement therefor, an amount
equal to the lesser of (i) the aggregate of all Prepayment Interest Shortfalls incurred in connection with Principal Prepayments
received in respect of the Mortgage Loans or Serviced Companion Loans (other than any Specially Serviced Loan, any Non-Serviced
Mortgage Loan, and any Defaulted Mortgage Loan), other than Principal Prepayments received in connection with the receipt
of Insurance Proceeds or Condemnation Proceeds or otherwise incurred with the

 

    	-182-

    	 

    

 

consent of the Special Servicer or the Controlling
Class Representative, during the most recently ended Prepayment Period, and (ii) the sum of (A) the aggregate Servicing
Fees with respect to each Mortgage Loan, Serviced Companion Loan, REO Mortgage Loan and REO Serviced Companion Loan for which Servicing
Fees are being paid in such Prepayment Period, up to a maximum rate of 0.0025% per annum for the related Distribution Date
and (B) all Prepayment Interest Excesses received during the related Prepayment Period (and net investment earnings thereon);
provided that the Master Servicer shall pay (without regard to clause (ii) above) the aggregate of
all Prepayment Interest Shortfalls otherwise described in clause (i) above incurred in connection with Principal
Prepayments received in respect of the Mortgage Loans during the most recently ended Prepayment Period to the extent such Prepayment
Interest Shortfalls were the result of the Master Servicer’s failure to enforce the related Mortgage Loan Documents. No Compensating
Interest Payments shall be made by the Master Servicer for any Non-Serviced Mortgage Loan. Any Compensating Interest Payments made
with respect to a Serviced Companion Loan shall be paid to the related Serviced Companion Loan Holder.

 

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 the related Co-Lender Agreement and not applied pursuant to
Section 3.06(a)(ii) of this Agreement) received with respect to a Mortgage Loan, Serviced Whole Loan or a Non-Serviced Mortgage
Loan (to the extent remitted to the Master Servicer by the related Other Master Servicer and, in any event, subject to the related
Co-Lender Agreement) during the related Prepayment 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), 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 Whole Loan;

 

(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 Whole Loan previously
determined to be Nonrecoverable Advances and previously reimbursed to the Master Servicer and/or 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 Whole Loan previously paid from the

 

    	-183-

    	 

    

 

Collection Account or Serviced Whole Loan Custodial
Account (and such amounts will be retained or deposited in the Collection Account or Serviced Whole Loan Custodial Account, as
applicable, 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;

 

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

 

The Special Servicer
is not required to remit Penalty Charges and Modification Fees received by it from the Mortgagor to the extent such Penalty Charges
and Modification Fees would be allocated to the Special Servicer pursuant to this Section 3.14.

 

(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 and Modification 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 and Modification
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 the 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 Companion
Loan Holders that are, in the case of any Certificateholder or 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 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 Companion Loan Holders or any regulatory authority seeking such access in respect of the Companion Loan Holders, to records
relating to the Companion Loans). Nothing in this Section 3.15 shall detract

 

    	-184-

    	 

    

 

from the obligation of the Master Servicer
and the Special Servicer to observe any applicable law prohibiting disclosure of information with respect to the Mortgagors, and
the failure of the Master Servicer and the 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 Companion Loan Holder or any regulatory
authority that may exercise authority over a Certificateholder or Companion Loan Holder, the Master Servicer and the Special Servicer
may each require payment from such Certificateholder or 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 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.

 

Upon the reasonable request
of (1) any Certifying Certificateholder or Companion Loan Holder, the Master Servicer may provide (or forward electronically) (at
the expense of such Certificateholder or Companion Loan Holder) copies of any operating statements, rent rolls and financial
statements obtained by the Master Servicer or the Special Servicer (provided that in no event shall an Excluded Controlling
Class Holder be entitled to Excluded Information with respect to an Excluded Controlling Class Loan with respect to which it is
a Borrower Party) or (2) any Controlling Class Certificateholder identified to the Master Servicer (with respect to non-Specially
Serviced Loans) or the Special Servicer (with respect to the Specially Serviced Loans) in an Investor Certification, the Master
Servicer or the Special Servicer, as applicable, shall provide (or forward electronically) (at the expense of such Controlling
Class Certificateholder) any Excluded Information in the Master Servicer’s or the Special Servicer’s possession, as
applicable (not accessible through the Certificate Administrator’s Website) relating to any Excluded Controlling Class Loan
with respect to which such Controlling Class Certificateholder is not an Excluded Controlling Class Holder.

 

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 Companion Loan if the disclosure of such items would
constitute a waiver of the attorney-client privilege.

 

    	-185-

    	 

    

 

Each of the Master Servicer
and Special Servicer, as appropriate, shall, without charge, make a knowledgeable Servicing Officer available via telephone to
verbally answer questions from the Operating Advisor (after the occurrence and during the continuance of a Control Termination
Event) and the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event),
on a monthly basis, during regular business hours at such time and for such duration as the Master Servicer, the Special Servicer,
the Operating Advisor and, prior to the occurrence and continuance of a Consultation Termination Event, the Controlling Class Representative
shall reasonably agree, regarding the performance and servicing of the Mortgage Loans and Serviced Whole Loans and/or related REO
Properties for which the Master Servicer or the Special Servicer, as applicable, is responsible. In connection with clause (ii)
above, the Special Servicer shall have no duty to the Trust Fund, the holders of the Controlling Class, the Controlling Class Representative
or any other Person to receive, consider or accept any advice from the Controlling Class Representative. In any event, the Operating
Advisor and the Controlling Class Representative 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 Whole Loans)
and/or REO Properties it intends to discuss. As a condition to such disclosure, the Controlling Class Representative 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 Mortgagor that is not Privileged Information, for review by
the Depositor, the Trustee, the Certificate Administrator, the Master Servicer, the Special Servicer and the Operating Advisor.

 

After the occurrence
and during the continuance of a Control Termination Event, the Special Servicer shall deliver to the Operating Advisor such reports
and other information produced or otherwise available to 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.

 

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 unless (i) with
respect to Privileged Information, pursuant to a Privileged Information Exception, or (ii) to the extent necessary to support its
conclusions in its Operating Advisor Annual Report required under Section 3.28 of this Agreement or to discharge its other
duties under this Agreement.

 

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

 

    	-186-

    	 

    

 

promptly
upon receipt thereof. No Master Servicer or 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 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 a Non-Serviced Mortgage
Loan) is acquired for the benefit of Certificateholders (or, with respect to a Serviced Whole Loan, for the benefit of the Certificateholders
and the related Serviced Companion Loan Holder(s)) (as a collective whole as if such Certificateholders and 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 the related 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 for federal income tax purposes at any time that any Certificate 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 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 related 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

 

    	-187-

    	 

    

 

(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. 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 with respect to any Non-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 Companion Loan Holder(s) (as a collective whole as if such Certificateholders
and, if applicable, the related Companion Loan Holder constituted a single lender), and, in connection therewith, the Special Servicer
shall only agree to the payment of management fees that it determines in its reasonable business judgment to be substantially 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)
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
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 registered Holders of CSAIL 2015-C4 Commercial Mortgage
Trust, Commercial Mortgage Pass-Through Certificates, Series 2015-C4 [in the case of an REO Property related to a Whole Loan: and
the related 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
one Business Day after receipt all revenues received by it with respect to any REO Property (other than Liquidation Proceeds, which
shall be remitted to the Collection Account), 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;

 

                                                    (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

 

    	-188-

    	 

    

 

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 Whole Loan, the related Serviced
Whole Loan Custodial Account, on a monthly basis prior to the related Master Servicer Remittance Date the Net REO Proceeds received
or collected from each REO Property during the related Prepayment Period, except that in determining the amount of 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 improvement was completed before default on the related Mortgage Loan or Serviced Whole Loan became
imminent, all within the meaning of Code Section 856(e)(4)(B); or

 

    	-189-

    	 

    

 

                                                   (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, the related Companion Loan Holder, the Certificate
Administrator and the Trustee (which opinion shall be an expense of the Trust Fund and, if the related Companion Loan is part of
a REMIC, the related 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(a) 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, the related 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

 

    	-190-

    	 

    

 

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

 

(b)              
When and as necessary, the Special Servicer shall send to the Trustee and the Certificate Administrator and the related
Companion Loan Holder 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) of this Agreement.

 

(c)              
Notwithstanding anything to the contrary, this Section 3.16 shall not apply to any REO Property related to a Non-Serviced
Mortgage Loan.

 

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

 

(a)              
The parties hereto may sell or purchase, or permit the sale or purchase of, a Mortgage Loan (excluding a Non-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 Section 2.03 and Section 9.01 of this Agreement, or (iii) (A) in
the case of a Mortgage Loan related to a Serviced Whole Loan in accordance with and subject to the provisions of the related Co-Lender
Agreement and Section 3.27 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 Mortgage Loan (excluding a Non-Serviced Mortgage Loan) or Serviced Whole Loan becoming a Defaulted Mortgage
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 Defaulted Serviced Whole Loan, the related Serviced Companion Loan Holder(s) (as a
collective whole as if such Certificateholders and, in the case of a Defaulted Serviced Whole Loan, the related Serviced Companion
Loan Holder(s), constituted a single lender) to attempt to sell such Defaulted Mortgage Loan (, the Special Servicer shall use
reasonable efforts to solicit offers for such Defaulted Mortgage Loan on behalf of the Certificateholders and, if applicable, the
related Serviced Companion Loan Holder(s) 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 Mortgage Loan. The
Special Servicer shall notify the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination
Event), the Operating Advisor (after the occurrence and during the continuance of a Control Termination Event) and any affected
Serviced Companion Loan Holder of any inquiries or offers received regarding the sale of any Defaulted Mortgage Loan. Any Companion
Loan that is part of a Defaulted Serviced Whole Loan 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.

 

    	-191-

    	 

    

 

(c)              
The Special Servicer shall give the Certificate Administrator, the Trustee, the Master Servicer, the related Companion Loan
Holder, the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event) and
the Operating Advisor (after the occurrence and during the continuance of a Control Termination Event), not less than five (5)
Business Days’ (but subject to paragraph (p) below with respect to a Serviced Whole Loan) prior written notice of its
intention to sell any Defaulted Mortgage Loan. No Interested Person shall be obligated to submit an offer to purchase any Defaulted
Mortgage 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 Mortgage Loan pursuant hereto.

 

(d)             
Whether any cash offer constitutes a fair price for any Defaulted Mortgage Loan for purposes of Section 3.17(b) of
this Agreement shall be determined by the Special Servicer, if the highest offeror is a Person other than an Interested Person,
and by the Trustee, if the highest offeror is an Interested Person (provided that the Trustee may not be an offeror) unless
(i) the offer is equal to or greater than the applicable Purchase Price, (ii) the offer is the highest offer received and (iii)
at least two other offers are received from independent third parties; 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. 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 Mortgage Loan pursuant to the immediately preceding
sentence), in determining whether any offer received from an Interested Person represents a fair price for any Defaulted Mortgage
Loan, the Trustee shall be supplied with and shall rely on the most recent Appraisal or updated Appraisal conducted in accordance
with this Agreement within the preceding six (6)-month period or, in the absence of any such Appraisal, on a new Appraisal. The
appraiser conducting any such new Appraisal shall be an Appraiser selected by (i) the Special Servicer if no Interested Person
is offering with respect to a Defaulted Mortgage Loan and (ii) the Trustee if an Interested Person is so offering. The cost
of any such Appraisal shall be covered by, and shall be reimbursable as, a Property Advance. In determining whether any such offer
from a Person other than an Interested Person constitutes a fair price for any such Defaulted Mortgage 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 six (6) months), and in determining whether any offer from an Interested Person
constitutes a fair price for any such Defaulted Mortgage Loan, any Appraiser shall be instructed to take into account, as applicable,
among other factors, the period and amount of any delinquency on the affected Mortgage Loan or Serviced Whole Loan, the occupancy
level and physical condition of the related Mortgaged Property and the state of the local economy. The Purchase Price for any Defaulted
Mortgage Loan (and any equivalent amount for any related Companion Loan) shall in all cases be deemed a fair price and the Trustee
will not be required to make a fair price determination if such offeror is an Interested Person; provided, however,
that with respect to an Interested Person, the requirements of the first sentence of this Section 3.17(d) must be satisfied.
Notwithstanding anything contained in this Section 3.17(d) to the contrary, if the Trustee is required to determine whether
a cash offer by an Interested Person constitutes a fair price, the Trustee may (at its option and at the expense of the 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 the subject REO Property that has been

 

    	-192-

    	 

    

 

selected with reasonable care
by the Trustee to determine if such cash offer constitutes a fair price for such REO Property. If the Trustee designates such a
third party to make such determination, the Trustee will be entitled to rely conclusively upon such third party’s determination.
The reasonable costs of all appraisals, inspection reports and broker opinions of value incurred by any such third party pursuant
to this paragraph will be covered by, and will be reimbursable by the Interested Person and if not paid, shall be reimbursed by
the Trust; provided that the Trustee may not engage a third party expert whose fees exceed a commercially reasonable amount
as determined by the Trustee.

 

(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 Pari Passu Companion Loan Holder in negotiating
and taking any other action necessary or appropriate in connection with the sale of any Defaulted 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 Serviced Whole Loan Custodial Account. Any sale of any Defaulted Mortgage 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 the rights of a holder of a mezzanine or companion loan, under the respective intercreditor or co-lender agreement,
respectively, to purchase a Mortgage Loan or Serviced Whole Loan, unless and until a Defaulted Mortgage Loan is sold pursuant to
this Section, the Special Servicer shall continue to service and administer the Mortgage 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 a Mortgage Loan, as is consistent with this Agreement and the Servicing Standard.

 

(g)             
Any sale of a Mortgage Loan or Serviced Whole Loan pursuant to this Section 3.17 shall be for cash only. The purchase
price for any Mortgage Loan or Serviced Whole Loan purchased under this Section 3.17 or any Non-Serviced Mortgage Loan sold
in accordance with the related Co-Lender Agreement or Other Pooling and Servicing Agreement shall be deposited into the Collection
Account or the related Serviced Whole Loan Custodial Account, as applicable, and the Certificate Administrator, upon receipt of
an Officer’s Certificate from the Master Servicer to the effect that such deposit has been made, shall release or cause to
be released to the purchaser of the Mortgage Loan or Serviced Whole Loan the related Mortgage File, and 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 Mortgage Loan or Serviced Whole Loan. In connection with any such purchase, the Special Servicer and

 

    	-193-

    	 

    

 

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 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 a Non-Serviced Mortgage Loan) on behalf of the Certificateholders and the related Serviced Companion Loan Holder (if applicable)
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 within the 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
purchased hereunder shall be deposited in the Collection Account or, if applicable, the related Serviced Whole Loan Custodial Account.
The Special Servicer shall notify the Controlling Class Representative (prior to the occurrence and continuance of a Consultation
Termination Event) and the Operating Advisor (after the occurrence and during the continuance of a Control Termination Event) of
any inquiries or offers received regarding the sale of any REO Property.

 

(j)               
The Special Servicer shall give the Trustee, the Certificate Administrator, the Master Servicer, the related Companion Loan
Holder, the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event) and
the Operating Advisor (after the occurrence and during the continuance of a Control Termination Event), not less than three (3)
Business Days’ prior written notice of its intention to sell any REO Property. 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 for purposes of Section 3.17(i) of this Agreement shall
be determined by the Special Servicer, if the highest offeror is a Person other than an Interested Person, and by the Trustee,
if the highest 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. In determining whether any offer received from an Interested
Person represents a fair price for any such REO Property, the Trustee shall be supplied with and shall rely on the most recent
Appraisal or updated Appraisal conducted in accordance with this Agreement within the preceding six (6)-month period or, in the
absence of any such Appraisal, on a new Appraisal. The appraiser conducting any such new Appraisal shall be an Appraiser selected
by the Special

 

    	-194-

    	 

    

 

Servicer if no Interested Person is offering with respect to an REO Property and selected by the Trustee if an Interested
Person is so offering. The cost of any such Appraisal shall be covered by, and shall be reimbursable as, a Property Advance. For
the avoidance of doubt, an offer equivalent to the Repurchase Price shall be deemed a fair price and the Trustee shall not be required
to make a fair price determination if such offeror is an Interested Person. 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 six (6) months), and in determining whether any offer from an Interested Person constitutes a fair price
for any such REO Property, any Appraiser shall be instructed to take into account, as applicable, among other factors, the period
and amount of any delinquency on the affected Mortgage Loan or Serviced Whole Loan, the occupancy level and physical condition
of the REO Property, the state of the local economy and the obligation to dispose of any REO Property within the time period specified
in Section 3.16 of this Agreement. The Purchase Price for any REO Property shall in all cases be deemed a fair price; provided,
however, that with respect to an Interested Person, the requirements of the first sentence of this Section 3.17(k)
must be satisfied. Notwithstanding anything contained in this Section 3.17(k) to the contrary, if the Trustee is required
to determine whether a cash offer by an Interested Person constitutes a fair price, the Trustee may (at its option and at the expense
of the Interested Person) designate an independent third party expert in real estate or commercial mortgage loan matters with at
least 5 years’ experience in valuing or investing in properties similar to the subject 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. If the Trustee
designates such a third party to make such determination, the Trustee will be entitled to rely conclusively upon such third party’s
determination. The reasonable costs of all appraisals, inspection reports and broker opinions of value incurred by any such third
party pursuant to this paragraph will be covered by, and will be reimbursable by the Interested Person; provided that the
Trustee will not engage a third party expert whose fees exceed a commercially reasonable amount as determined by the Trustee.

 

(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 Companion Loan Holder in negotiating and taking any other action
necessary or appropriate in connection with the sale of any Defaulted Mortgage Loan or REO Property, 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 Serviced Whole Loan Custodial Account. Any sale of any Defaulted Mortgage Loan or REO Property shall be final and without
recourse to the Trustee, the Certificate Administrator or the Trust Fund or any related Companion Loan Holder (except such recourse
to the Trust Fund and the related 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

 

    	-195-

    	 

    

 

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 Mortgage Loan or REO Property if the Special Servicer determines (in consultation
with the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event) and, in
the case of a Serviced Whole Loan or an REO Property related to a Serviced Whole Loan, the related affected Serviced Companion
Loan Holder(s)), 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 sale of a Serviced Whole Loan or an REO Property that corresponds to a Serviced Whole
Loan, the related affected Serviced Companion Loan Holder(s) (as a collective whole as if such Certificateholders and, if applicable,
the related affected Serviced 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 Whole Loan
or an REO Property that corresponds to a Serviced Whole Loan, the related affected Serviced Companion Loan Holder(s) (as a collective
whole as if such Certificateholders and, if applicable, the related affected Serviced 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).

 

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

 

(o)              
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 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 an appropriate mezzanine loan holder and shall provide such notices to 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.

 

(p)              
With respect to each Serviced Whole Loan, the parties hereto acknowledge that the related Co-Lender Agreement provides that
if such Serviced Whole Loan becomes a Defaulted Serviced Whole Loan, and if the Special Servicer determines to sell the related
Mortgage Loan in accordance with this Section 3.17, then the Special Servicer will be required to sell the related
Serviced Companion Loan(s) together with the related Mortgage Loan as one whole loan in accordance with this Agreement and subject
to any rights of the related holder of such Serviced Companion Loan(s) under the related Co-Lender Agreement. Notwithstanding anything
to the contrary herein, the Special Servicer shall not sell the Pari Passu Companion Loans of a Defaulted Serviced Whole Loan without
the written consent of the related Serviced Companion Loan Holder (provided that such consent is not required if such Serviced

 

    	-196-

    	 

    

 

Companion Loan Holder is the related Mortgagor or an Affiliate of the related Mortgagor unless the Special Servicer has delivered
to such Serviced Companion Loan Holder: (a) at least 15 Business Days prior written notice of any decision to attempt to sell such
Defaulted Serviced Whole Loan; (b) at least 10 days prior to the proposed sale date, a copy of each bid package (together with
any material amendments to such bid packages) received by the Special Servicer in connection with any such proposed sale; (c) at
least 10 days prior to the proposed sale date, a copy of the most recent appraisal for such Defaulted Serviced Whole Loan, and
any documents in the Servicing File reasonably requested by the related Serviced Companion Loan Holder that are material to the
price of such Serviced Whole Loan; and (d) until the sale is completed, and a reasonable period of time (but no less time than
is afforded to other offerors and the Controlling Class Representative) prior to the proposed sale date, all information and other
documents being provided to other offerors and all leases or other documents that are approved by the Master Servicer or the Special
Servicer in connection with the proposed sale; provided that such Serviced Companion Loan Holder may waive as to itself
any of the delivery or timing requirements set forth in this sentence. The related Serviced Companion Loan Holder and its Companion
Loan Holder Representative will each be permitted to make offers to purchase, and either such party is permitted to be the purchaser
at any sale of, a Defaulted Serviced Whole Loan.

 

(q)              
Notwithstanding anything herein to the contrary, any party identified in the related Co-Lender Agreement or Other Pooling
and Servicing Agreement (which, if the identified party is the holder of the Non-Serviced Mortgage Loan, shall mean the Controlling
Class Certificateholder 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 a Non-Serviced Mortgage Loan in accordance with the terms and conditions
set forth in such Co-Lender Agreement and Other Pooling and 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, the Non-Serviced Mortgage
Loan or the related Companion Loan or any Mortgage Loan.

 

(r)              
With respect to any Non-Serviced Mortgage Loan that becomes a “Defaulted Mortgage Loan” (as such term is defined
pursuant to the terms of the applicable Other Pooling and Servicing Agreement), and with respect to any REO Property related to
a Non-Serviced Mortgage Loan, the liquidation of such Non-Serviced Mortgage Loan or such REO Property shall be administered by
the applicable Other Special Servicer in accordance with the applicable Other Pooling and Servicing Agreement and the related Co-Lender
Agreement. Any such sale of a Non-Serviced Mortgage Loan or any related REO Property pursuant to the applicable Other Pooling and
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 Operating Advisor, the Certificate Administrator or the Trustee shall have
any liability to any Certificateholder with respect to the purchase price for such Non-Serviced Mortgage Loan or such REO Property
accepted on behalf of the Trust.

Section 3.18         
Additional Obligations of the Master Servicer; Inspections Obligation to Notify Ground Lessors; Delivery of Certain Reports
to the 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 Mortgage Loan (but not a Non-Serviced Mortgage Loan) or Serviced
Whole 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 Mortgage Loans with an outstanding principal balance of $2,000,000
(commencing in 2017) or more and at least once every other calendar year with respect to such Mortgaged Property relating to Mortgage
Loans with an outstanding principal balance of less than $2,000,000 (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 Mortgage Loan or Serviced Whole Loan 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 Mortgage Loan or Serviced Whole Loan 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 from amounts in 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.

 

(b)              
The Master Servicer shall, as to each Mortgage Loan (excluding any Non-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 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 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 Companion Loan related thereto.

 

(d)              
If required under the Co-Lender Agreement, the Master Servicer shall promptly deliver to each 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 Companion Loan.

 

    	-198-

    	 

    

 

(e)          The Master Servicer is hereby authorized to exercise any rights granted under an Other Pooling and Servicing Agreement in
favor of the Trust (or a party on its behalf) as the holder of the related Non-Serviced Mortgage Loan to obtain information
from the related Other Master 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 Other Master Servicer, upon request, such information
in the Master Servicer’s possession as the Other Master Servicer reasonably requests in order to determine whether an advance
similar to a P&I Advance would be “nonrecoverable.”

 

Section 3.19     Lockbox Accounts, Escrow Accounts. The Master Servicer shall administer each Lockbox Account and Escrow Account in
accordance with the related Mortgage or Loan Agreement or Lockbox Agreement, if any, and administer any letters of credit pursuant
to the related letter of credit agreement and the Mortgage 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 Mortgage Loan Documents is permitted, but not required, to apply such amounts to prepay the related Mortgage Loan (or Serviced
Whole Loan), neither the Master Servicer nor the Special Servicer shall apply such amounts to prepay the Mortgage Loan (or Serviced
Whole Loan) until after the occurrence of an event of default under the Mortgage Loan that may result in the Mortgage Loan (or
Whole Loan) being accelerated or becoming a Specially Serviced Loan.

 

Section 3.20      Property Advances.

 

(a)          Except with respect to a Non-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. The Special Servicer shall give the Master Servicer,
the Trustee and any affected Companion Loan Holder not less than five (or, in the case of emergency 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. In addition, the Special Servicer
shall provide the Master Servicer, the Trustee and any affected Companion Loan Holder with such information in its possession as
the Master Servicer, the Trustee or such 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 (or, if appropriate, any party under the applicable Other Pooling and Servicing Agreement in
the case of a Non-Serviced Mortgage Loan) to the Master Servicer of a required Property Advance shall be deemed to be a determination
by the Special Servicer (or such other party under the applicable Other Pooling and Servicing Agreement) that such requested Property
Advance is not a Nonrecoverable Advance, and the Master Servicer shall be entitled to conclusively rely on such determination.
Although the Special Servicer (or, if appropriate, any party under the applicable Other Pooling and Servicing Agreement in the
case of a Non-Serviced Mortgage Loan) may determine whether a Property Advance is a Nonrecoverable Advance, the Special Servicer
will have no right to make an affirmative determination that any Property Advance to be made (or contemplated to be made) by the
Master Servicer or the Trustee is, or would be, recoverable; provided that this

 

    	-199-

    	 

    

 

sentence
shall 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), will not be ultimately recoverable. In the absence of a determination by the Special Servicer (or,
if appropriate, a party under the applicable Other Pooling and Servicing Agreement in the case of a Non-Serviced Mortgage Loan)
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
(or, if appropriate, a party under the applicable Other Pooling and Servicing Agreement in the case of a Non-Serviced Mortgage
Loan) 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 (but this statement shall not be construed to entitle the Special Servicer to 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). 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 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 Whole Loan, notwithstanding that the terms
of such Mortgage Loan or Serviced Whole Loan so provide.

 

(b)          The Master Servicer shall notify the Trustee, the Special Servicer and any related 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 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 11.04 of this Agreement.

 

(c)          Neither the Master Servicer nor the Trustee shall be permitted to make a Property Advance as to any Mortgage Loan or Serviced
Whole Loan or REO Property if the Master Servicer, the Special Servicer or the Trustee determines that such Advance will be a Nonrecoverable
Advance. The determination by the Master Servicer or the Trustee that it has made (or, the determination by the Special Servicer
that the Master Servicer or the Trustee has

 

    	-200-

    	 

    

 

made) a Nonrecoverable
Advance or the determination by the Master Servicer, the Special Servicer or the Trustee that any proposed Property 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 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 as set forth in this Section 3.20(c).
In making such recoverability determination, 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 Whole Loan 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. In addition, any such Person may update or change its recoverability determinations at
any time (but not reverse any other Person’s determination that an Advance is a Nonrecoverable Advance) and 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.

 

The determination by
the Master Servicer or the Special Servicer that a Property Advance has become a Nonrecoverable Property Advance or that any proposed
Property Advance, if made pursuant to this Section 3.20 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 Property Advance, shall be conclusive
and binding on the Master Servicer (in the case of such a determination by the Special Servicer) and the Trustee; provided
that this sentence 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.

 

The determination by
the Master Servicer, the Special Servicer or the Trustee that a Property Advance has become a Nonrecoverable Property Advance or
that any proposed Property Advance, if made pursuant to this Section 3.20 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 Property Advance, shall
be evidenced by an Officer’s Certificate delivered on or prior to the next Master Servicer Remittance Date to the Companion
Loan Holders (and the related Other Master Servicer and Other Special Servicer, if applicable), in the case of any Serviced Whole
Loan, 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 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 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),

 

    	-201-

    	 

    

 

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 Trustee shall be entitled to rely,
conclusively, on any determination by the Master Servicer or the 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 or the Trustee that a Property Advance is or, if made, would be a Nonrecoverable Advance. The Trustee, in determining
whether or not a Property Advance previously made is, or a proposed Property Advance, if made, would be, a Nonrecoverable Advance
shall use its good faith business judgment.

 

(d)          The Master 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 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 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 Mortgage 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 a Non-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 an emergency situation or on an urgent basis, 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 an emergency situation or on an urgent basis, 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. 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.

 

Section 3.21     Appointment of Special Servicer; Asset Status Reports.

 

(a)          Midland Loan Services, a Division of PNC Bank, National Association is hereby appointed as the initial Special Servicer

Rule 17g-5 Information Provider’s Website pursuant to Section 11.13 of this Agreement, the Rule 17g-5 Information

the Controlling Class Representative if they are the same entity or affiliates of each other. Such Asset Status Report shall be
consistent with the Servicing Standard and set forth the following information to the extent reasonably determinable or applicable:

 

(i)           summary of the status of the related Mortgage Loan or Serviced Whole Loan and any negotiations with the Mortgagors;

 

(ii)          if a Servicing Transfer Event has occurred and is continuing:

 

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

 

(B)           the most

(F)           a description of any amendment, modification or waiver of a material term of any ground lease; and

    	-203-

    	 

    

 

non-recourse carve-out under the related Mortgage Loan or Serviced Whole Loan and (ii) any determination
not to pursue a deficiency judgment against the related Mortgagor or guarantor;

 

(iii)          a description

(iv)          the alternative courses of action that were or are being considered by the Special Servicer in connection with the proposed

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.

 

For so long as there
is no continuing Control Termination Event, if within 10 Business Days (or, in the case of an Asset Status Report prepared prior
to making a determination of an Acceptable Insurance Default, 20 Business Days) of receiving an Asset Status Report, the Controlling
Class Representative (except with respect to any Excluded Loan) does not disapprove such Asset Status Report in writing, then the
Controlling Class Representative 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 Servicer may
not take any action that is contrary to applicable law, the Servicing Standard or the terms of the applicable Mortgage Loan Documents.
If, prior to the occurrence and continuance of any Control Termination Event and such Asset Status Report does not relate to an
Excluded Loan, the Controlling Class Representative disapproves such Asset Status Report within 10 Business Days (or, in the case
of an Asset Status Report prepared prior to making a determination of an Acceptable Insurance Default, 20 Business Days) of receipt,
the Special Servicer will revise such Asset Status Report and deliver to the Operating Advisor (after the occurrence and during
the continuance of a Control Termination Event), the Controlling Class Representative (prior to the occurrence and continuance
of a Consultation Termination Event and only if such Asset Status Report does not relate to an Excluded Loan), the Certificate
Administrator, the related Companion Loan Holders and, for posting to the Rule 17g-5 Information Provider’s Website
pursuant Section 11.13 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. Prior to the occurrence and continuance of any Control
Termination Event, the Special Servicer shall revise such Asset Status Report as described above until the Controlling Class Representative
(only if an Excluded Loan is not involved) shall fail to disapprove such revised Asset Status Report in writing within 10 Business
Days (or, in the case of an Asset Status Report prepared prior to making a

 

    	-204-

    	 

    

 

determination
of an Acceptable Insurance Default, 20 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). 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 approved or deemed approved pursuant to the terms of this Section. In any event, for so long as a Control Termination
Event has not occurred and is not continuing and only if an Excluded Loan is not involved, if the Controlling Class Representative
does not approve an Asset Status Report within 60 Business Days from the first submission thereof, the Special Servicer shall
take such action as set forth in the most recently submitted Asset Status Report; provided such action does not violate
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 Holders,
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 (or 20 Business
Day period, if applicable) 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 (or 20 Business Day period, if applicable) would materially
and adversely affect the interest of the Certificateholders and the related Serviced Companion Loan Holder (if applicable) and
the Special Servicer has made a reasonable effort, prior to the occurrence and continuance of any Control Termination Event, to
contact the Controlling Class Representative. The foregoing shall not relieve the Special Servicer of its duties to comply with
the Servicing Standard. To the extent that the Special Servicer received notice of an Excluded Controlling Class Loan (in the
form of Exhibit M-1C or M-1D), any Asset Status Report or Excluded Information delivered with respect to an Excluded
Controlling Class Loan shall be sent via email to cmbsexcludedloan@wellsfargo.com pursuant to Section 3.32 and shall be
labeled by the Special Servicer with “Excluded Controlling Class Loan” followed by the loan number and loan name.

 

After the occurrence
and during the continuance of a Control Termination 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 ten (10) 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 of Certificates that were previously included in the Control Eligible Certificates), 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 (other than any Asset Status Report with respect
to an Excluded Loan) in connection with each Asset Status Report prior to finalizing and executing such Asset Status Report and
the Controlling Class Representative shall be permitted to propose alternative courses of action within ten (10) days of receipt
of each Asset Status Report. The Special Servicer shall consider

 

    	-205-

    	 

    

 

any such
proposals from the Operating Advisor and/or the Controlling Class Representative 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. In the event that the Operating Advisor or the Controlling Class Representative does not propose alternative
courses of action within ten (10) days after receipt of such Asset Status Report, the Special Servicer shall implement the Asset
Status Report as proposed by the Special Servicer. For the avoidance of doubt, the Controlling Class Representative shall not
have any consultation or approval rights with respect to an Asset Status Report that relates to an Excluded Loan.

 

Notwithstanding anything
to the contrary herein, after the occurrence and during the continuance of a Consultation Termination Event, the Controlling Class
Representative shall have no right to receive any Asset Status Report or otherwise consult with the Special Servicer with respect
to any matter set forth therein. After the occurrence and during the continuance of a Control Termination Event, the Controlling
Class Representative shall have no right to consent to any Asset Status Report under this Section 3.21(b). From and after
the Closing Date, the Controlling Class Representative shall have no right to receive any Asset Status Report related to an Excluded
Loan or otherwise to consent or object thereto under this Section 3.21(b) or otherwise consult with the Special Servicer
with respect to any matter set forth therein.

 

Notwithstanding the foregoing
or any other provision of this Agreement to the contrary, with respect to a Serviced Whole Loan, the related Serviced Companion
Loan Holder (or its Companion Loan Holder Representative) shall, at all times contemplated by the related Co-Lender Agreement,
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 as set forth in Section 3.27(d) of this Agreement.

Class Loan with respect to which such Excluded Controlling Class Holder is a Borrower Party.

(f)          Notwithstanding the foregoing, neither the Master Servicer nor the Special Servicer shall follow any advice, direction or
consultation provided by the Operating Advisor, any Serviced Companion Loan Holder, any Companion Loan Holder Representative or
the Controlling Class Representative that would require or cause the Master Servicer or the Special Servicer, as applicable, to
violate any applicable law, be inconsistent with the Servicing Standard or any Co-Lender Agreement, require or cause the Master
Servicer or the Special Servicer, as applicable, to violate provisions of this Agreement, require or cause the Special Servicer
or Master Servicer to violate the terms of any Co-Lender Agreement, any Mortgage Loan or Serviced Whole Loan, or expose any Certificateholder
or any party to this Agreement or their Affiliates, officers, directors or agents to any claim, suit or liability, cause either
Trust REMIC to fail to qualify as a REMIC for federal income tax purposes, result in the imposition of a “prohibited transaction”
or “prohibited contribution” tax under the REMIC Provisions, or the imposition of a tax upon either Trust REMIC, or
materially expand the scope of the Master Servicer’s or the Special Servicer’s, as applicable, responsibilities under
this Agreement or any Co-Lender Agreement. In addition, neither the Master Servicer nor the Special Servicer is under any obligation
to act upon any recommendation of the Operating Advisor.

 

Section 3.22      Transfer of Servicing Between Master Servicer and Special Servicer; Record Keeping.

 

(a)          Upon determining
that any Mortgage Loan or Serviced Whole Loan has become a Specially Serviced Loan, the Master Servicer shall promptly give written
notice thereof to the Special Servicer, any related Companion Loan Holder (in the case of a Serviced Whole Loan), the Operating
Advisor, the Certificate Administrator, the Trustee and, prior to the occurrence and continuance of a Consultation Termination
Event, the Controlling Class Representative, and, for posting to the Rule 17g-5 Information Provider’s Website pursuant
to Section 11.13 of this Agreement, the Rule 17g-5 Information Provider and shall deliver a copy of the Servicing
File to the Special Servicer and concurrently provide a copy of such Servicing File to the Operating Advisor and shall use its
reasonable efforts to provide the Special Servicer with all information, documents (but excluding the original documents constituting
the Mortgage File, but including copies thereof) and records (including records stored electronically on computer tapes, magnetic
discs and the like) relating to the Mortgage Loan or Serviced Whole Loan and reasonably requested by the Special Servicer to enable
it to assume its duties hereunder with respect thereto without acting through a Sub-Servicer. The Master Servicer shall use its
reasonable efforts to comply with the preceding sentence within five (5) Business Days of the date such Mortgage Loan and/or Serviced
Companion Loan became a Specially Serviced Loan and in any event shall continue to act as Master Servicer and administrator of
such Mortgage Loan and/or Serviced Companion Loan until the Special Servicer has commenced the servicing of such Mortgage Loan
and/or Serviced Companion Loan, which shall occur upon the receipt by the Special Servicer of the Servicing File. With respect
to each such Mortgage Loan and/or Serviced Companion 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 Mortgage Loan and/or Serviced Companion 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 Special Servicer who shall send such notice to the related Mortgagor.

 

    	-207-

    	 

    

 

Upon determining that
a Specially Serviced Loan has become a Corrected Mortgage Loan, the Special Servicer shall immediately give written notice thereof
to the Master Servicer, the Trustee, the Operating Advisor, the Certificate Administrator, any related Companion Loan Holder and,
prior to the occurrence and continuance of a Consultation Termination Event, the Controlling Class Representative, and, for posting
to the Rule 17g-5 Information Provider’s Website pursuant to Section 11.13 of this Agreement, the Rule 17g-5
Information Provider and, upon giving such notice and the return of the Servicing File to the Master Servicer, such Mortgage Loan
and/or Serviced Companion 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 Mortgage Loan and/or Serviced Companion Loan
shall terminate and the obligations of the Master Servicer to service and administer such Mortgage Loan and/or Serviced Companion
Loan as a Mortgage Loan and/or Serviced Companion 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 the definition
of “Mortgage File” for inclusion in the related Mortgage File (to the extent such documents are in the possession
of the Special Servicer) and copies of any additional related Mortgage Loan or Serviced Whole Loan information, including
correspondence with the related Mortgagor, and the Special Servicer shall promptly provide copies of all of the foregoing to the
Master Servicer as well as copies of any analysis or internal review prepared by or for the benefit of the Special Servicer.

 

(c)          Notwithstanding the provisions of subsections (a) and (b) of this Section 3.22, the Master Servicer
shall maintain ongoing payment records with respect to each of the Specially Serviced Loans and, upon request, shall provide the
Special Servicer and the Operating Advisor with any information reasonably required by the Special Servicer or the Operating Advisor
to perform its duties under this Agreement to the extent such information is within its possession. Upon request, the Special Servicer
shall provide the Master Servicer and the Operating Advisor with any information reasonably required by the Master Servicer or
the Operating Advisor to perform its duties under this Agreement to the extent such information is within its possession.

 

Section 3.23     Interest
Reserve Account. The Certificate Administrator shall establish and maintain the Interest Reserve Account. The Interest Reserve
Account shall be established and maintained as an Eligible Account. On each Master Servicer Remittance Date occurring in February
and on any Master Servicer Remittance Date occurring in January which occurs in a year that is not a leap year (commencing
in 2016) (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 each Mortgage Loan that accrues
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 Loan Rate, on the respective Stated Principal Balance, as of the close of business on the
Distribution

 

    	-208-

    	 

    

 

Date in the
month preceding the month in which such Master Servicer Remittance Date occurs, to the extent the applicable 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 occurring in March (or February, if
such Distribution Date is the final Distribution Date) of each calendar year, the Certificate Administrator shall transfer to
the Lower-Tier Distribution Account the aggregate of all Withheld Amounts on deposit in the Interest Reserve Account.

 

Section 3.24     Modifications, Waivers, Amendments and Master Servicer Decisions.

 

(a)          (i) With
respect to non-Specially Serviced Loans, the Master Servicer (subject to the Special Servicer’s consent if the related modification,
waiver, amendment, consent or other action constitutes a Major Decision or is otherwise not a Master Servicer Decision) or (ii) with
respect to any Specially Serviced Loan, the Special Servicer, in each case subject to the consultation rights (if any) of the
Operating Advisor following a Control Termination Event, or the consent or consultation of the Controlling Class Representative,
or any related holder of a Pari Passu Companion Loan or its Companion Loan Holder Representative (as applicable), to modify, waive
or amend any term of any Mortgage Loan (other than any Non-Serviced Whole Loan) or Serviced Whole Loan if such modification, waiver,
amendment, consent or other action (A) is consistent with the Servicing Standard and (B) would not constitute a “significant
modification” of such Mortgage Loan (other than any Non-Serviced Whole Loan) or Serviced Whole Loan pursuant to Treasury
Regulations Section 1.860G-2(b) and would not otherwise (1) cause either Trust REMIC to fail to qualify as a REMIC for
federal income tax purposes or (2) result in the imposition of a tax upon either Trust REMIC or the Trust (including but
not limited to the tax on “prohibited transactions” as defined in Code Section 860F(a)(2) and the tax on contributions
to a REMIC set forth in Code Section 860G(d), but not including the tax on “net income from foreclosure property”
under Code Section 860G(c)). The Master Servicer and the Special Servicer may rely on an Opinion of Counsel with respect
to such determination.

 

In
addition, with respect to any Mortgage Loan (other than any Non-Serviced Mortgage Loan) that is not a Specially Serviced
Loan, the consent of the Special Servicer shall be required for any modification, waiver, amendment, consent or other action that
constitutes a Major Decision pursuant to Section 6.09(a) of this Agreement or is otherwise not a Master Servicer Decision
pursuant to Section 3.24(e), and the Special Servicer shall obtain the consent of for so long as a Control Termination
Event has not occurred and is not continuing, the Controlling Class Representative with regard to any modification, waiver, amendment,
consent or other action for which the Master Servicer is recommending approval that constitutes a Major Decision. The Special
Servicer shall also obtain the consent of the Controlling Class Representative and under the circumstances contemplated by the
prior sentence, with respect to any modification, waiver, amendment, consent or other action with regard to any Specially Serviced
Loan to the extent provided in Section 6.09(a) of this Agreement.

 

No modification, waiver
or amendment of any Co-Lender Agreement related to a Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any Serviced Companion
Loan, or an action to enforce rights with respect thereto, in each case, in a manner that materially and

 

    	-209-

    	 

    

 

adversely
affects the rights, duties and obligations of the Special Servicer or the Master Servicer, as applicable, shall be permitted without
the prior written consent of the Special Servicer or the Master Servicer, as applicable.

 

When
the Special Servicer’s consent is required and the Master Servicer is recommending approval with respect to non-Specially
Serviced Loans, the Master Servicer shall promptly provide the Special Servicer with written notice of any request for modification,
waiver, amendment, consent or other action that is a Major Decision or is otherwise not a Master Servicer Decision 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 the Controlling Class Representative may reasonably request
to withhold or grant its consent, and in all cases the Special Servicer shall be entitled (subject to the consultation rights
of the Operating Advisor, the consent or consultation rights of the Controlling Class Representative, or the consultation rights
of any related Companion Loan Holder or its Companion Loan Holder Representative (as applicable)) to approve or disapprove any
modification, waiver, amendment, consent or other action that constitutes a Major Decision or is otherwise not a Master Servicer
Decision. Subject to Section 3.10 of this Agreement, the Special Servicer shall have 15 Business Days (or, with respect
to a Serviced Whole Loan, such longer period as required by the related Co-Lender Agreement for review by any related Companion
Loan Holder or its Companion Loan Holder Representative) (or 30 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 Major Decision or such non-Master Servicer Decision. Prior
to the end of such 15 Business Day period or such longer period if required by the applicable Co-Lender Agreement or 30-day period,
as applicable, for so long as a Control Termination Event has not occurred and is not continuing with respect to a Major Decision
for which the Master Servicer is recommending approval, the Special Servicer is required to notify the Controlling Class Representative,
of such request for approval and provide its written analysis and recommendation with respect thereto. Following such notice,
the Controlling Class Representative 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 written recommendation and analysis of the Master
Servicer or the Special Servicer, as applicable, and any other information it may reasonably request to approve any recommendation
of the Special Servicer or the Master Servicer relating to any request for approval for a Major Decision. In any event, subject
to the Co-Lender Agreement for any Whole Loan, if the Controlling Class Representative, if required, does not respond to a request
for approval by 5:00 p.m. on the 10th Business Day or such longer period if required by the applicable Co-Lender Agreement or
20th day, as applicable, after receipt of the applicable recommendation and analysis 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 Controlling Class Representative and if the Special Servicer does not respond to a request for approval within the required
15 Business Days or such longer period if required by the applicable Co-Lender Agreement or 30 days, as applicable, the Master
Servicer may deem its recommendation approved by the Special Servicer. With respect to any non-Specially Serviced Loan, the Master
Servicer, without the consent of the Special Servicer, shall be responsible to determine whether to consent to or approve any
request by the related Mortgagor with respect to any action that is a Master Servicer Decision.
  

    	-210-

    	 

    

 

No
modification, waiver or amendment of any Co-Lender Agreement related to a Mortgage Loan (other than a Non-Serviced Mortgage Loan)
and any Serviced Companion Loan, or an action to enforce rights with respect thereto, in each case, in a manner that materially
and adversely affects the rights, duties and obligations of the Special Servicer or the Master Servicer, as applicable, shall
be permitted without the prior written consent of the Special Servicer or the Master Servicer, as applicable.

 

(b)          All modifications,
waivers or amendments of any Mortgage Loan or Serviced Whole 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, shall notify in writing the Trustee,
the Certificate Administrator, the Depositor, any related Serviced Companion Loan Holder(s) (in the case of a Serviced Whole Loan
which, for so long as any Serviced Companion Loan 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), the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination
Event), the Operating Advisor (after the occurrence and during the continuance of a Control Termination Event) and, for posting
to the Rule 17g-5 Information Provider’s Website pursuant to Section 11.13 of this Agreement, the Rule 17g-5
Information Provider, of any modification, waiver or amendment of any term of any Mortgage Loan or Serviced Whole Loan and the
date thereof, and shall deliver a copy to the Trustee, any related Serviced Companion Loan Holder(s) (in the case of a Serviced
Whole Loan which, for so long as any Serviced Companion Loan has been included in an Other Securitization Trust, shall be deemed
to be the related Other Master Servicer under the related Other Pooling and Servicing Agreement, unless the notifying party has
received written notice otherwise), the Controlling Class Representative (prior to the occurrence and continuance of a Consultation
Termination Event) and the Operating Advisor (after the occurrence and during the continuance of a Control Termination Event)
and an original to the Custodian 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 requirements with respect to delivery of
an assumption agreement shall be governed by Section 3.09.

 

(c)          Any modification
of any Mortgage Loan Documents that requires obtaining a Rating Agency Confirmation pursuant to such Mortgage Loan Documents,
or any modification that would eliminate, modify or alter the requirement of obtaining a Rating Agency Confirmation in such Mortgage
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 Whole Loan becomes a Specially Serviced Loan, the Special Servicer shall request from the
Certificate Administrator the name of the current Controlling Class Representative and shall request from the Master Servicer
the name of the current related Companion Loan Holder(s). 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(s) of such current related Companion Loan

 

    	-211-

    	 

    

 

Holder
from the Master Servicer, the Special Servicer shall notify the related Companion Loan Holder that the related Serviced Whole
Loan became a Specially Serviced Loan. The Certificate Administrator shall be responsible for providing the name of the 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 (on a reasonably prompt basis) such list to the Special
Servicer and the Master Servicer at the expense of the Trust Fund.

 

(e)          With
respect to any non-Specially Serviced Loan, and subject to the rights of the Special Servicer and the Controlling Class Representative
under Section 6.09 of this Agreement, the Master Servicer, without the consent of the Special Servicer or the Controlling
Class Representative and without any Rating Agency Confirmation, shall be responsible to determine whether to consent to or approve
any of the following requests by the related Mortgagor (each, a “Master Servicer Decision”):

 

(A)         approving
routine leasing activity, including the granting of subordination and nondisturbance and attornment agreements and consents involving
routine leasing activities that (1) do not involve a ground lease or lease of an outparcel, (2) affect an area less than the lesser
of (i) 20,000 square feet and (ii) 10% of the net rentable area of the related Mortgaged Property and (3) is not with respect to
a lease that otherwise constitutes a “major lease” or “material lease,” if applicable, under the related
Mortgage Loan Documents;

 

(B)          approving
any immaterial waiver affecting the timing of receipt of financial statements from any Mortgagor; provided that such
financial statements are delivered no less often than quarterly and within 60 days after the end of the calendar quarter;

 

(C)          approving annual budgets for the related Mortgaged
Property; provided that no such budget (1) is with respect to a Mortgaged Property that is on the CREFC®
Servicer Watch List, or (2) provides for the payment of any material (more than 25%) increases in operating expenses or payments
to entities actually known by the Master Servicer to be affiliates of the related Mortgagor (excluding affiliated managers paid
at fee rates agreed to at the origination of the related Mortgage Loan);

 

(D)          subject
to other restrictions in this Agreement regarding Principal Prepayments, waiving any provision of a Mortgage Loan or Serviced Whole
Loan requiring a specified number of days’ notice prior to a Principal Prepayment;

 

(E)          approving
non-material modifications, consents or waivers (other than modifications, consents or waivers specifically prohibited under this
Section 3.24) in connection with a defeasance permitted by the terms of this Agreement, and subject to certain conditions,
including in certain cases, delivery of an Opinion of Counsel (which 

 

    	-212-

    	 

    

 

Opinion of Counsel shall be at the expense of the related
Mortgagor) to the effect that such modification, waiver or consent would not cause either Trust REMIC to fail to qualify as a REMIC
under the Code or result in a “prohibited transaction” under the REMIC Provisions or cause the Grantor Trust to fail
to qualify as a grantor trust for federal income tax purposes;

 

(F)          approving
consents with respect to non-material rights-of-way and non-material easements and consent to subordination of the related Mortgage
Loan or Serviced Whole Loan to such non-material rights-of-way or easements; provided that the Master Servicer has determined
in accordance with the Servicing Standard that such right-of-way or easement does not materially affect the then-current use or
value of the related Mortgaged Property, the security intended to be provided by the related Mortgage or the Mortgagor’s ability
to make payments with respect to the related Mortgage Loan or Serviced Whole Loan;

 

(G)         granting
waivers of minor covenant defaults (other than financial covenants);

 

(H)         as
permitted under the related Mortgage Loan Documents, payment from any escrow, reserve, or letter of credit except releases of
any escrows, reserve accounts or letters of credit held as performance or “earn-out” escrows or reserves unless
both (1) required pursuant to the specific terms of the related Mortgage Loan or Serviced Whole Loan and (2) for which there
is no lender discretion;

 

(I)          approving
a change of the property manager or franchise change at the request of the related Mortgagor so long as (1) the successor property
manager is not affiliated with the related Mortgagor and is a nationally or regionally recognized manager of similar properties,
and (2) the subject Mortgage Loan or Serviced Whole Loan does not have an outstanding principal balance in excess of the lesser
of $8,500,000 or 2% of the then aggregate principal balance of the Mortgage Loans and Serviced Whole Loans and (3) to the extent
the lender is not required to consent or approve such change under the Mortgage Loan Documents;

 

(J)          for
all Mortgage Loans and Serviced Whole Loans, subject to the satisfaction of any conditions precedent set forth in the related Mortgage
Loan Documents, approving disbursements of any holdback amounts in accordance with the related Mortgage Loan Documents provided
that such disbursements are required pursuant to the specific terms of the related Mortgage Loan or Serviced Whole Loan and for
which there is no material lender discretion (other than confirming the satisfaction of the other conditions to the transaction
set forth in the related Mortgage Loan Documents that do not include any other approval);

 

(K)        any
non-material modifications, waivers or amendments not provided for in clauses (A) through (J) above, which are necessary
to cure any ambiguities or to correct scrivener’s errors in the terms of the related Mortgage Loan or Serviced Whole Loan;

 

    	-213-

    	 

    

 

(L)         consent to releases of non-material, non-income
producing parcels of a Mortgaged Property that do not materially affect the use or value of the Mortgaged Property or the ability
of the related Mortgagor to pay amounts due in respect of the Mortgage Loan or Companion Loan as and when due provided such releases
are required by the related Mortgage Loan documents and there is no lender discretion permitted under the Mortgage Loan documents;
and

 

(M)        consent to actions related to condemnation of non-material,
non-income producing parcels of the Mortgaged Property that do not materially affect the use or value of the Mortgaged Property
or the ability of the related Mortgagor to pay amounts due in respect of the Mortgage Loan or Companion Loan when due so long
as such consent is not with respect to (1) a condemnation settlement or (2) a determination to apply casualty proceeds or condemnation
awards to the reduction of the debt rather than to the restoration of the Mortgaged Property.

 

(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 Whole Loan 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 Mortgage Loan or Serviced Whole Loan beyond a date that is three (3) years prior to the Rated
Final Distribution Date; or

 

(ii)           if the Mortgage Loan or Serviced Whole Loan is secured by a ground lease, extend the Maturity Date of such Mortgage Loan
or Serviced Whole 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 Mortgage Loan Documents require the Master Servicer or the Special Servicer, as applicable, to
calculate (or require the related 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 Mortgage
Loan, then, unless then permitted by the REMIC

 

    	-214-

    	 

    

 

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

 

(i)           If
and to the extent that the Trust, as holder of a Non-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 Other Pooling
and Servicing Agreement, such rights shall be exercised by the Controlling Class Representative or, following a Consultation Termination
Event, the Operating Advisor, in accordance with Section 3.01(j). The Master Servicer and the Special Servicer shall only
be obligated to forward any requests received from the related Other Master Servicer or the related Other Special Servicer, as
applicable, for such consent and/or consultation to the Controlling Class Representative (unless, with respect to consent rights,
a Control Termination Event has occurred and is continuing or, with respect to consultation rights, a Consultation Termination
Event has occurred) or, following a Consultation Termination Event with respect to any consultation rights, to the Operating Advisor,
and shall have no right or obligation to exercise any such consent or consultation rights. For the avoidance of doubt, the foregoing
provisions of this paragraph shall not impose any consent rights on the Operating Advisor with respect to the Non-Serviced Mortgage
Loan.

 

Section 3.25     Additional Obligations with Respect to Certain Mortgage Loans.

 

(a)          With respect to each Mortgage Loan (other than any Non-Serviced Mortgage Loan) with a Stated Principal Balance in excess
of $35,000,000, with respect to 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 Mortgage 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.

 

With respect to any Mortgage
Loan (other than a Non-Serviced Mortgage Loan), if any mezzanine loan is directly or indirectly secured by any equity interest
of the related Mortgagor, the Master Servicer (if the related Mortgage Loan is a non-Specially Serviced Loan) or the Special Servicer
(if the related Mortgage Loan is a Specially Serviced Loan) shall perform the obligations of the Trust, as holder of the related
Mortgage Loan, or its servicer under the related mezzanine loan intercreditor agreement.

 

Section 3.26         
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
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 refrain
from obtaining such reimbursement for some or all such portion of the

 

    	-215-

    	 

    

 

Nonrecoverable
Advance during the one-month Prepayment 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 (unless a Control Termination Event has occurred and is continuing, in which case the
Controlling Class Representative shall be consulted with unless a Consultation Termination Event has occurred and is continuing).
If the Master Servicer or the Trustee makes such an election in its sole discretion to defer reimbursement with respect to all
or a portion of a Nonrecoverable Advance (together with interest thereon), then such Nonrecoverable Advance (together with interest
thereon) or portion thereof shall continue to be fully reimbursable in the subsequent Collection Period (subject, again, to the
same sole 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 or the Trustee to refrain from the reimbursement of a particular Nonrecoverable Advance or portion thereof
during the one-month Prepayment Period ending on the related Determination Date for any Distribution Date, the Master Servicer
or the Trustee shall further be authorized to wait for principal collections to be received before making its determination of
whether to refrain from the reimbursement of a particular Nonrecoverable Advance or portion thereof) until the end of such
Prepayment Period; provided, however, that if, at any time the Master Servicer or the Trustee, as applicable, determines
that the reimbursement of a Nonrecoverable Advance during a one-month Prepayment Period will exceed the full amount of the principal
portion of general collections deposited in the Collection Account for such Distribution Date, then the Master Servicer or the
Trustee, as applicable, shall, through a posting to the Rule 17g-5 Information Provider’s Website pursuant to Section
11.13 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
or the Trustee, as applicable, determines in its sole discretion that waiting 15 days after such a notice could jeopardize the
Master 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 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 has not timely received from the
Trustee information requested by the Master Servicer to consider in determining whether to defer reimbursement of a Nonrecoverable
Advance; provided that, if clause (1), (2) or (3) apply, the Master Servicer or the
Trustee, as applicable, shall, through a posting to the Rule 17g-5 Information Provider’s Website pursuant to Section
11.13 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 11.13 of this Agreement, the Master 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 or the Trustee to refrain from 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 Master Servicer or the Trustee 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

 

    	-216-

    	 

    

 

Collection Period or to constitute a waiver
or limitation on the right of the Master Servicer or the Trustee to otherwise be reimbursed for such Nonrecoverable Advance immediately
(together with interest thereon). Any such election by the Master Servicer or the Trustee shall not be construed to impose any
duty on the 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 refrain from reimbursing itself or obtaining reimbursement for any
Nonrecoverable Advance or portion thereof with respect to any one or more Prepayment 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 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 refrain or not to refrain from 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 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 or the Trustee, as applicable,
or a right of the Certificateholders. Nothing herein shall give the Master 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 Property
Advance unless the Trustee determines such Property Advance to be a Nonrecoverable Advance.

 

Section 3.27     Companion
Loan Co-Lender 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 Whole Loan is purchased from, repurchased from or substituted out of, the Trust Fund, the subsequent holder thereof
shall be bound by the terms of the Co-Lender Agreement and shall assume the rights and obligations of the holder of the note(s)
that represent the related Mortgage Loan under such Co-Lender Agreement. All portions of the related Mortgage File and (to the
extent provided under the related 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(s) that represent the related Mortgage Loan (as a result of such purchase, repurchase or substitution) and (except for the
actual Note(s)) on behalf of the holder of the Note(s) that represent the Companion Loan. Thereafter, such Mortgage File shall
be held by the holder of the Note(s) that represent the related Mortgage Loan or a custodian appointed thereby for the benefit
thereof, on behalf of itself and the holder of the related Companion Loan as their interests appear under the Co-Lender Agreement.
If the related Servicing File is not already in the possession of such party, it shall be delivered to the master

 

    	-217-

    	 

    

 

servicer
or special servicer, as the case may be, under any separate servicing agreement for the Whole Loans.

 

(b)          With respect to each
Companion Loan that is part of a Serviced Whole Loan, notwithstanding any rights the Operating Advisor or the Controlling Class
Representative hereunder may have to consult with respect to any action or other matter with respect to the servicing of such
Companion Loan, to the extent the related Co-Lender Agreement provides that such right is exercisable by the related Companion
Loan Holder or is exercisable in conjunction with any related Companion Loan Holder or its Companion Loan Holder Representative,
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 Companion Loan Holder or its Companion
Loan Holder Representative, as applicable. Additionally, notwithstanding anything in this Agreement to the contrary but subject
to Section 3.17(p) (as to consent rights) and Section 3.27(d) below (as to consultation rights), the Master Servicer
or Special Servicer, as applicable, shall consult with, seek the approval of, or obtain the consent of the holder of any Companion
Loan or its Companion Loan Holder Representative with respect to any matters with respect to the servicing of such Companion Loan
to the extent required under related Co-Lender Agreement and shall not take such actions requiring consent of or consultation
with the 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 Companion Loan Holder as required under the Co-Lender Agreement.

 

(c)          With respect to each Serviced Whole Loan, 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 Whole Loan:

 

(i)           (A) the amount of the distribution from the related Serviced Whole Loan 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 Whole Loan;

 

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

 

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

 

    	-218-

    	 

    

 

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

 

(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 Companion Loan Holder by electronic means (which
may include posting such information pursuant to the applicable CREFC(R) reports on the Master Servicer’s
website).

 

(d)          Unless otherwise stated in the related Co-Lender Agreement and notwithstanding anything in this Agreement to the contrary,
with respect to each Serviced Whole Loan (i) the Special Servicer (with respect to Specially Serviced Loans) or the Master Servicer
(with respect to non-Specially Serviced Loans), as applicable, shall be required to provide copies of any notice, information and
report that is required to be provided to the Controlling Class Representative pursuant to this Agreement with respect to any Major
Decisions or the implementation of any recommended actions outlined in an Asset Status Report relating to such Serviced Whole Loan,
to any related non-controlling Companion Loan Holder (or its Companion Loan Holder Representative), within the same time frame
it is required to provide to the Controlling Class Representative (for this purpose, without regard to whether such items are actually
required to be provided to the Controlling Class Representative under this Agreement due to the occurrence and continuance of a
Control Termination Event or a Consultation Termination Event) and (ii) the Special Servicer, upon request, shall be required to
consult with any related non-controlling Serviced Companion Loan Holder or, after the occurrence of a Consultation Termination
Event, the Operating Advisor) on a strictly non-binding basis, to the extent having received such notices, information and reports,
such related Companion Loan Holder requests consultation with respect to any such Major Decisions or the implementation of any
recommended actions outlined in an Asset Status Report relating to the related Serviced Whole Loan, and consider alternative actions
recommended by such related Serviced Companion Loan Holder; provided that after the expiration of a period of ten (10) Business
Days from the delivery to such related Companion Loan Holder by the Master Servicer or Special Servicer, as applicable, of written
notice of a proposed action, together with copies of the notice, information and report required to be provided to the Controlling
Class Representative, the Master Servicer or Special Servicer, as applicable, shall no longer be obligated to consult with such
related Companion Loan Holder or consider alternate actions recommended by the related Companion Loan Holder, whether or not such
related Companion Loan Holder has responded within such ten (10) Business Day period (unless the Master Servicer or the Special
Servicer, as applicable, proposes a new course of action that is materially different from the action previously proposed, in which
case such ten (10) Business Day period shall be deemed to begin anew from the date of such proposal and delivery of all information
relating thereto); provided, further, that, if the Master Servicer or Special Servicer, as applicable, determines
(consistent with the Servicing Standard) that immediate action is necessary to protect the interests of the Certificateholders,
the Master Servicer or Special Servicer, as applicable, may take such action without waiting for such response; provided,
further, that, if the Master Servicer or Special Servicer, as applicable, takes

 

    	-219-

    	 

    

 

any action
in accordance with the immediately preceding proviso, the Master Servicer or Special Servicer, as applicable, shall provide the
related Companion Loan Holder with prompt written notice following such action, including a reasonably detailed explanation of
the basis. Notwithstanding the consultation rights of any related Companion Loan Holder (or its Companion Loan Holder Representative)
set forth in the immediately preceding sentence, the Master Servicer or Special Servicer, as applicable, may make any Major Decision
or take any action set forth in the Asset Status Report before the expiration of the aforementioned ten (10) Business Day period
if the Master Servicer or Special Servicer, as applicable, determines that immediate action with respect thereto is necessary
to protect the interests of the Certificateholders and the related Companion Loan Holder. The Master Servicer or the Special Servicer,
as applicable, shall not be obligated at any time to follow or take any alternative actions recommended by a Companion Loan Holder
(or its representative) with respect to a Serviced Whole Loan.

 

(e)          In addition to the consultation rights of a Companion Loan Holder (or its Companion Loan Holder Representative) provided
in the immediately preceding paragraph, a Companion Loan Holder shall have the right to attend (in person or telephonically) annual
meetings with the Special Servicer at the offices of the Special Servicer upon reasonable notice and at times reasonably acceptable
to the Special Servicer in which servicing issues related to the related Serviced Whole Loan are discussed.

 

(f)           Upon receipt of written notice of the transfer of all or a portion of any Serviced Companion Loan, the Master Servicer shall
notify the Special Servicer, the Trustee, the Custodian and the Certificate Administrator of the identity and notice information
of the successor Companion Loan Holder(s) (or its representative) to the extent the Master Servicer has such information, such
written notice is not also addressed to such applicable party and the Master Servicer has not previously provided such information
thereto; provided that, if a Companion Loan has been included in an Other Securitization Trust, the Companion Loan Holder
will be deemed to be the related master servicer under the related Other Pooling and Servicing Agreement for purposes of providing
notice(s), reports and any other information to the Companion Loan Holder under this Agreement, unless the notifying party has
received written notice otherwise. Subject to Section 11.04, the Master Servicer may reasonably rely on the information
provided to the Master Servicer regarding the identity and/or contact information of a Serviced Companion Loan Holder (or its representative).
Each of the Special Servicer, the Trustee, the Custodian and the Certificate Administrator shall be entitled to rely on such information
so provided by the Master Servicer.

 

Notwithstanding
the foregoing, the Special Servicer shall not follow any advice, direction or consultation provided by the Operating Advisor,
any Serviced Companion Loan Holder (or its representative) or the Controlling Class Representative that would require or
cause the Special Servicer to violate any applicable law, be inconsistent with the Servicing Standard or any Co-Lender
Agreement, require or cause the Special Servicer to violate provisions of this Agreement or the terms of any Mortgage Loan or
Serviced Whole Loan, expose any Certificateholder or any party to this Agreement or their affiliates, officers, directors or
agents to any claim, suit or liability, cause either Trust REMIC to fail to qualify as a REMIC for federal income tax
purposes, result in the imposition of “prohibited transaction” or “prohibited contribution” tax under the
REMIC provisions of the Code or the imposition of a tax upon either

 

    	-220-

    	 

    

 

 

Trust REMIC or
the loss of REMIC status, or materially expand the scope of the Special Servicer’s responsibilities under this Agreement
or any Co-Lender Agreement.

 

Section 3.28     Appointment
and Duties of the Operating Advisor.

 

(a)          Pentalpha Surveillance
LLC is hereby appointed to serve as the initial Operating Advisor.

 

(b)          The Operating Advisor, as an independent contractor, shall review the Special Servicer’s operational practices in
respect of Specially Serviced Loans, consult with the Special Servicer and perform each other obligation of the Operating Advisor
as set forth in this Agreement solely on behalf of the Trust and in the best interest of, and for the benefit of, the Certificateholders
(as a collective whole as if such Certificateholders and, with respect to a Serviced Companion Loan that is a Pari Passu Companion
Loan, the related holder(s) of such Pari Passu Companion Loan constituted a single lender) and not any particular Class of those
Certificateholders, as determined by the Operating Advisor in the exercise of its good faith and reasonable judgment (the “Operating
Advisor Standard”). The Operating Advisor shall not owe any fiduciary duty to the Master Servicer, the Special Servicer
or any other Person in connection with this Agreement.

 

(c)          Prior to the occurrence and continuance of a Control Termination Event, the Operating Advisor shall promptly review (i) all
information available to Privileged Persons on the Certificate Administrator’s Website with respect to the Special Servicer,
assets on the CREFC® Servicer Watch List and Specially Serviced Loans and (ii) each Final Asset Status Report.

 

(d)          (i) After the occurrence and during the continuance of a Control Termination Event, the Operating Advisor shall review
the Special Servicer’s operational practices in light of the Servicing Standard and the requirements of this Agreement, with
respect to the resolution and/or liquidation of the Specially Serviced Loans.

 

(ii)          After the occurrence and during the continuance of a Control Termination Event, based on the Operating Advisor’s review
of any annual compliance statement and any assessment of compliance delivered to the Operating Advisor pursuant to Section 10.07
and Section 10.08 of this Agreement, as applicable, any attestation report delivered to the Operating Advisor pursuant to
Section 10.09 of this Agreement, any Asset Status Report and other information (other than any communications between the
Controlling Class Representative, or a Serviced Companion Loan Holder (or its Companion Loan Holder Representative), as applicable,
on the one hand, and the Special Servicer, on the other hand, that would be Privileged Information) delivered to the Operating
Advisor by the Special Servicer, the Operating Advisor shall (if any Mortgage Loans were Specially Serviced Loans during the prior
calendar year) prepare and deliver to the Depositor, the Rule 17g-5 Information Provider (which shall promptly post such Operating
Advisor Annual Report on the Rule 17g-5 Information Provider’s Website), the Trustee and the Certificate Administrator
(which shall promptly post such Operating Advisor Annual Report on the Certificate Administrator’s Website), within 120 days
of the end of the prior calendar year an annual report (the “Operating Advisor Annual Report”),

 

    	-221-

    	 

    

 

substantially
in the form of Exhibit R of this Agreement (which form may be modified or altered as to either its organization or
content by the Operating Advisor, subject to compliance of such form with the terms and provisions of this Agreement; provided,
further, that in no event shall the information or any other content included in the Operating Advisor Annual Report contravene
any provision of this Agreement) setting forth the Operating Advisor’s assessment of the Special Servicer’s performance
of its duties under this Agreement during the prior calendar year on a platform-level basis with respect to the resolution and
liquidation of Specially Serviced Loans and with respect to each Asset Status Report delivered to the Operating Advisor by the
Special Servicer during the prior calendar year. As used in connection with the Operating Advisor Annual Report, the term “platform-level
basis” refers to the Special Servicer’s performance of its duties as they relate to the resolution and/or liquidation
of Specially Serviced Loans, taking into account the Special Servicer’s specific duties under this Agreement as well as the
extent to which those duties were performed in accordance with the Servicing Standard, with reasonable consideration by the Operating
Advisor of the items required to be reviewed by it pursuant to this Agreement.

 

Subject to
the restrictions in this Agreement, including, without limitation, this Section 3.28, each such Operating Advisor Annual
Report shall (A) identify any material deviations (i) from the Servicing Standard and (ii) from the Special Servicer’s
obligations under this Agreement with respect to the resolution or liquidation of Specially Serviced Loans, (B) comply with
all of the confidentiality requirements regarding Privileged Information applicable to the Operating Advisor described in this
Agreement and, (C) in the event a lack of access to Privileged Information limits or prohibits the Operating Advisor from performing
its duties under this Agreement, the Operating Advisor shall describe any such limitations in the Operating Advisor Annual Report,
and 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 (a) the Special
Servicer and (b) for so long as a Consultation Termination Event does not exist, the Controlling Class Representative, 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. Notwithstanding the foregoing,
no Operating Advisor Annual Report shall be required from the Operating Advisor with respect to the Special Servicer if during
the prior calendar year no Asset Status Report was prepared by the Special Servicer in connection with a Specially Serviced Loan
or REO Property. In addition, 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 the entity that was acting as a Special Servicer
as of December 31 in the prior calendar year and is continuing in such capacity through the date of such Operating Advisor Annual
Report.

 

    	-222-

    	 

    

 

Notwithstanding
anything in this Agreement to the contrary, (i) the Operating Advisor’s assessment of the Special Servicer’s performance
shall be based on the provisions of this Agreement and (ii) so long as Midland Loan Services, a Division of PNC Bank, National
Association is acting as Special Servicer, then such Special Servicer shall provide the Operating Advisor reasonable access, at
such Special Servicer’s offices during normal business hours, to such Special Servicer’s policies and procedures. The
Operating Advisor will be permitted to review such policies and procedures but will not be permitted to retain hard copies and
will not be provided with any electronic copies or soft copies. The Operating Advisor shall keep all information contained in the
policies and procedures strictly confidential, except (A) the Operating Advisor may disclose such information if (i) such information
becomes generally available and known to the public other than as a result of a disclosure directly or indirectly by the Operating
Advisor, or (ii) such disclosure is required by applicable law, as evidenced by an opinion of counsel (which shall be an Operating
Advisor Expense) delivered to the Operating Advisor and the Special Servicer and (B) the Operating Advisor may disclose a particular
portion of the policies and procedures solely when necessary to support specific conclusions concerning allegations of material
deviations from the Servicing Standard (i) in the Operating Advisor Annual Report, or (ii) in connection with a recommendation
by the Operating Advisor to replace Midland Loan Services, a Division of PNC Bank, National Association as the Special Servicer
pursuant to the provisions of this Agreement. Notwithstanding the foregoing, the Operating Advisor will be permitted to share such
information with its Affiliates and any subcontractors of the Operating Advisor to the extent reasonably necessary to perform the
Operating Advisor’s obligations under this Agreement and provided such Operating Advisor Affiliates and subcontractors agree
in writing prior to their receipt of such information to be bound by the same confidentiality provisions applicable to the Operating
Advisor. The Operating Advisor’s assessment may not take into account the fact that Midland Loan Services, a Division of
PNC Bank, National Association limited the Operating Advisor’s access to such Special Servicer’s written policies and
procedures pursuant to the provisions of this Agreement. Nothing set forth herein shall limit or affect the scope of the Operating
Advisor’s platform level review in connection with its preparation of the Operating Advisor Annual Report, provided that
the Operating Advisor’s access to or reliance upon such Special Servicer’s written policies and procedures shall be
subject to the terms of this paragraph. During any period when the Special Servicer is not Midland Loan Services, a Division of
PNC Bank, National Association, or an Affiliate of Midland Loan Services, a Division of PNC Bank, National Association, the requirements
and limitations contained in this paragraph with respect to such Special Servicer shall be null and void, and the Operating Advisor
shall have adequate and timely access to the policies and procedures of any successor special servicer as the Operating Advisor
determines necessary to fulfill its duties under this Agreement.

 

(e)          Prior to the occurrence and continuance of a Control Termination Event, the Special Servicer will forward any Appraisal
Reduction Amount and net present value calculations used in the Special Servicer’s determination of what course of action
to take in connection with the workout or liquidation of a Specially Serviced Loan to the Operating Advisor after such calculations
have been finalized. The Operating Advisor shall review such calculations but may not opine on, or otherwise call into question
such Appraisal Reduction

 

    	-223-

    	 

    

 

Amount and/or
net present value calculations; provided, however, that if the Operating Advisor discovers a mathematical error
contained in such calculations, then the Operating Advisor shall notify the Special Servicer and the Controlling Class Representative
of such error.

 

(f)           After the occurrence and during the continuance of a Control Termination Event, after the calculation but prior to the utilization
by the Special Servicer of any of the calculations related to (i) Appraisal Reduction Amounts or (ii) net present value
used in the Special Servicer’s determination of the course of action to be taken in connection with the workout or liquidation
of a 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 3.28, in the event the Operating Advisor does not agree with the mathematical calculations or the application of
the applicable non-discretionary portions of the 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 related 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. The Certificate Administrator shall be entitled to conclusively
rely on such third-party calculation.

 

(g)          After the occurrence and during the continuance of a Control Termination Event, the Special Servicer shall consult (on a
non-binding basis) with the Operating Advisor in connection with any Major Decision and consider alternative actions recommended
by the Operating Advisor, but only to the extent consultation with, or consent of, the Controlling Class Representative would have
been required prior to the occurrence and continuance of such Control Termination Event.

 

(h)          Subject to the requirements of confidentiality imposed on the Operating Advisor herein (including without limitation in
respect of Privileged Information), the Operating Advisor shall respond to Inquiries 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

 

    	-224-

    	 

    

 

by Privileged
Persons from time to time in accordance with the terms of Section 4.02(a) of this Agreement.

 

(i)           Subject to the Privileged Information Exception, the Operating Advisor will be obligated to keep confidential any Privileged
Information received from the Special Servicer, Controlling Class Representative, or any Serviced Companion Loan Holder (or its
Companion Loan Holder Representative) in connection with the exercise of the rights of the Controlling Class Representative, or
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.

 

(j)           The Operating Advisor shall keep all Privileged Information confidential and shall not disclose such Privileged Information
to any Person (including Certificateholders other than the Controlling Class Representative (for so long as a Consultation Termination
Event does not exist)), 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 will be permitted to share Privileged Information with its affiliates and
any subcontractors of the Operating Advisor that agree in writing to be bound by the same confidentiality provisions applicable
to the Operating Advisor. Each party to this Agreement that receives Privileged Information from the Operating Advisor with a notice
stating that such information is Privileged Information shall not disclose such Privileged Information to any Person without the
prior written consent of the Special Servicer and, unless a Consultation Termination Event has occurred and is continuing, the
Controlling Class Representative (with respect to any Mortgage Loan other than any Non-Serviced Whole Loan) other than pursuant
to a Privileged Information Exception.

 

(k)          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 or the Serviced Whole Loan Custodial Account, as applicable, pursuant to Section 3.06
or Section 3.06A of this Agreement, as applicable. In addition, the Operating Advisor Consulting Fee shall be payable
to the Operating Advisor with respect to each Major Decision for which the Operating Advisor has consultation 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 and Section 3.06A of this Agreement (or the Serviced Whole Loan Custodial Accounts),
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. When 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,

Section 3.29     Rating
Agency Confirmation.

 

(a)          Notwithstanding the terms of any related Mortgage Loan Documents or other provisions of this Agreement, if any action under
any Mortgage Loan Documents or this Agreement requires Rating Agency Confirmation as a condition precedent to such action, if the
party (the “Requesting Party”) required to obtain such Rating Agency Confirmation from each Rating Agency has
made a request to any Rating Agency for such Rating Agency Confirmation and, within 10 Business Days of the Rating Agency Confirmation
request being posted to the Rule 17g-5 Information Provider’s Website, such Rating Agency has not replied to such request
or has responded in a manner that indicates that such Rating Agency is neither reviewing such request nor waiving the requirement
for Rating Agency Confirmation, then such Requesting Party shall be required to confirm (through direct communication and not by
posting any confirmation on the 17g-5 Information Provider’s Website) that the applicable Rating Agency has received the
Rating Agency Confirmation request, and, if it has, promptly request the related Rating Agency Confirmation again (which may also
be through direct communication). The circumstances described in the preceding sentence are referred to in this Agreement as a
“RAC No-Response Scenario”. Once the Requesting Party has sent a request for a Rating Agency Confirmation to
the 17g-5 Information Provider, such Requesting Party, may, but shall not be obligated to send such request directly to the Rating
Agencies in accordance with the procedures set forth in Section 11.13(k).

 

If there is no response
to such Rating Agency Confirmation request within five (5) Business Days of such second request in a RAC No-Response Scenario or
if such Rating Agency has responded in a manner that indicates such Rating Agency is neither reviewing such request nor waiving
the requirement for Rating Agency Confirmation then (x) with respect to any condition in any Mortgage Loan Document 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), then the Requesting Party (or, if the Requesting
Party is the related Mortgagor, then the Master Servicer (with respect to the non-Specially Serviced Loans) or the Special Servicer
(with respect to the Specially Serviced Loans and REO Mortgage Loans), as applicable) shall determine (with the consent of the
Controlling Class Representative (unless a Control Termination Event has occurred and is continuing) or consultation with the Controlling
Class Representative (unless a Consultation Termination Event has occurred and is continuing) or which consent shall be pursued
by the Special Servicer and deemed given if such Controlling Class Representative 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 whether such action would be in accordance with the
Servicing Standard, and if the Requesting Party (or if the Requesting Party is the related

 

    	-226-

    	 

    

 

Mortgagor,
then the Master Servicer (with respect to non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced
Loans and REO Mortgage Loans)) determines that such action would be in accordance with the Servicing Standard, except as provided
in Section 3.29(b), then the requirement to obtain a Rating Agency Confirmation shall not apply, (y) with respect
to a replacement of the Master Servicer or Special Servicer, such condition shall be considered satisfied if (i) the applicable
replacement master servicer or special servicer is rated at least “CMS3” (in the case of the master servicer) or “CSS3”
(in the case of a special servicer), if Fitch is the non-responding Rating Agency; (ii) 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 commercial mortgage backed securitization transaction serviced by the applicable servicer prior to
the time of determination, if KBRA is the non-responding Rating Agency; (iii) as certified in writing by the replacement master
servicer or special servicer, as applicable, it was appointed to act as the master servicer or special servicer, as applicable,
on a transaction level basis with respect to at least one commercial mortgage loan securitization in which Moody’s has rated
one or more classes of the related securities issued that are still outstanding and Moody’s 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 any such securities, prior to the time of determination, if Moody’s is the non-responding Rating Agency; and (iv) the
replacement master servicer or replacement special servicer is acting as master servicer or special servicer, as applicable, in
a commercial mortgage loan securitization that was rated by a Rating Agency within the 12-month period prior to the date of determination
and Morningstar has not qualified, downgraded or withdrawn the then-current rating or ratings of one or more classes of CMBS certificates
citing servicing concerns with the replacement master servicer or replacement special servicer, as applicable, as the sole or
material factor in such rating action, if Morningstar is the non-responding Rating Agency; 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 commercial mortgage-backed securities 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
request made by the Master Servicer, Special Servicer, Certificate Administrator, Operating Advisor or Trustee, as applicable,
pursuant to this Agreement, shall be made in writing, which writing shall contain a cover page indicating the nature of the Rating
Agency Confirmation request, and shall contain all back-up material reasonably necessary for the Rating Agency to process such
request, subject to Section 11.13. Such written Rating Agency Confirmation request shall be provided in electronic format
in accordance with Section 11.13(b) and the Master Servicer, Special Servicer. Certificate Administrator, Operating Advisor
or Trustee, as applicable, shall be required to send the Rating Agency Confirmation request to the Rating Agencies in accordance

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 3.29(a) without receiving any
required Rating Agency Confirmation, such Requesting Party (or the Master Servicer or the Special Servicer, as applicable) shall
provide electronic written notice in accordance with Section 11.13(b) of the action taken for the particular item at such
time and the Master Servicer, Special Servicer, Certificate Administrator or Trustee, as applicable, shall be required to send
the Rating Agency Confirmation request to the Rating Agencies in accordance with Section 11.13(b).

 

(b)          Notwithstanding anything to the contrary in Section 3.29(a), for purposes of 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 Rating Agency Confirmation requirement as to which the Master Servicer (with respect to
non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans and REO Mortgage Loans), as applicable,
would have been permitted to make a determination pursuant to Section 3.29(a)(x) shall be deemed to have been satisfied
(it being understood that the Master Servicer or the Special Servicer, as applicable, shall in any event review the conditions
required under the related Mortgage Loan Documents with respect to such defeasance, release or substitution and confirm to its
satisfaction in accordance with the Servicing Standard that such conditions (other than the requirement for a Rating Agency Confirmation)
have been satisfied).

 

(c)          For all other matters or actions (i) that are not specifically discussed in clauses (x), (y)
or (z) of Section 3.29(a) above or (ii) that are not the subject of a Rating Agency Declination, the proposed action
may 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 the related Serviced Mortgage Loan, the related Serviced Whole Loan 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, Special Servicer, Trustee, Certificate Administrator, Controlling Class Representative
or applicable Certificateholders, 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, and will be permitted to be waived by the Master Servicer and the Special
Servicer on, and will be deemed to be satisfied or not to apply on, the same terms and conditions applicable to obtaining Rating
Agency Confirmations, as set forth in this Agreement; provided that the Master Servicer, Special Servicer, Trustee, Certificate
Administrator, Controlling Class Representative or applicable Certificateholders, as applicable, depending on which is seeking
the subject Companion Loan Rating Agency Confirmation, shall forward to one or more of its counterpart (i.e., the Other

Trust to the extent not borne by the related Mortgagor, and in such format as the sender and recipient may reasonably agree, (i)
the request for such Companion Loan Rating Agency Confirmation at least two (2) Business Days before it is sent to the applicable
Companion Loan Rating Agency, (ii) all materials forwarded to the Rule 17g-5 Information Provider under this Agreement in
connection with seeking the Rating Agency Confirmation(s) for the applicable Relevant Action at approximately the same time that
such materials are forwarded to the Rule 17g-5 Information Provider, and (iii) any other materials that the applicable Companion
Loan Rating Agency may reasonably request in connection with such Companion Loan Rating Agency Confirmation promptly following
such request.

 

(e)          Each of the Master Servicer and the Certificate Administrator shall, promptly following receipt of written request from
the Special Servicer, provide to the Special Servicer the contact information for an Other Master Servicer, an Other Special Servicer,
an Other Trustee, an Other Certificate Administrator and the Rule 17g-5 Information Provider’s counterpart for an Other

Administrator or the related Other Special Servicer, as the case may be, in each case with reasonable promptness following request
therefor by a party to the related Other Pooling and Servicing Agreement.

 

In connection with the
sale of any Non-Serviced Whole Loan by any Other Special Servicer, upon receipt of any notices or materials required to be furnished

Agreement, the Special Servicer shall, prior to the occurrence and continuance of a Control Termination Event, forward such materials
to the Controlling Class Representative for its consent, if such consent is required (or for consultation, if consultation is required).
The Special Servicer may (with the consent of the Controlling Class Representative prior to the occurrence and continuance of a
Control Termination Event or after consultation with the Controlling Class Representative prior to the occurrence and continuance
of a Consultation Termination Event) waive any timing or delivery requirements related to such sale to the extent set forth in
the related Co-Lender Agreement.

 

With respect to any Non-Serviced
Mortgage Loan, the Controlling Class Representative, prior to the occurrence and continuance of a Consultation Termination Event,
or the Operating Advisor, following the occurrence and during the continuance of a Control Termination Event, shall be entitled

Excluded Controlling Class Loans). None of the Master Servicer, the Special Servicer or the Operating Advisor shall have any obligations
to separately label and deliver any Excluded Information in accordance with this Section 3.32(a) until such party has received
written notice with respect to the related Excluded Controlling Class Loan in the form of Exhibit M-1C to this Agreement.

 

(b)          Nothing set forth in this Agreement shall prohibit the Controlling Class Representative or any Controlling Class Certificateholder
from receiving, requesting or reviewing any Excluded Information relating to any Excluded Controlling Class Loan with respect to
which the Controlling Class Representative or such Controlling Class Certificateholder is not a Borrower Party and, if such Excluded

Directing Certificateholder or Controlling Class Certificateholder that is not a Borrower Party with respect to the related Excluded
Controlling Class Loan shall be permitted to obtain such information in accordance with Section 4.02 of this Agreement.

the Class X Strip Rate of 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. 

 

    	-235-

    	 

    

 

With respect to any distribution
in respect of unreimbursed Realized Losses previously allocated to a Class and interest thereon, any such amount with respect to
such Class shall be allocated first, to unreimbursed Realized Losses previously allocated to such Class, and then,
to interest on such unreimbursed Realized Losses.

 

(c)             (i)  On any Distribution Date, any Yield Maintenance Charge collected on the Mortgage Loans as of the related
Determination Date shall be distributed to Holders of the Classes of Certificates as follows: (a) pro rata, between (i)
the group (the “YM Group A”) of Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A and Class
A-S Certificates, pro rata, and (ii) the group (the “YM Group B” and collectively with the YM Group A,
the “YM Groups”) of Class X-B, Class B, Class C, Class D, Class X-D and Class E Certificates, based upon the
aggregate amount of principal distributed to the Classes of Principal Balance Certificates in each YM Group on such Distribution
Date; and (b) as among the respective Classes of Certificates in each YM Group in the following manner: (1) on a pro rata
basis in accordance with their respective entitlements in those Yield Maintenance Charges, to each Class of Principal Balance Certificates
in such YM Group in an amount equal to the product of (x) a fraction whose numerator is the amount of principal distributed to
such Class of Principal Balance Certificates on such Distribution Date and whose denominator 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 with respect to such Class of Principal Balance Certificates, and (z) the aggregate amount of such
Yield Maintenance Charge allocated to such YM Group and (2) the portion of such Yield Maintenance Charge allocated to such YM Group
remaining after such distributions to the applicable Class(es) of Principal Balance Certificates in such YM Group to the Class
of Class X Certificates in such YM Group, and in the case of the YM Group B, on a pro rata basis in accordance with their
respective reductions in their Notional Amounts on such Distribution Date, to the Class X-B and Class X-D Certificates.

 

After the Distribution
Date on which the Certificate Principal Balances of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class A-S, Class
B, Class C, Class D and Class E Certificates have been reduced to zero, all Yield Maintenance Charges collected with respect to
the Mortgage Loans will be distributed pro rata to the Holders of the Class X-D Certificates, regardless of whether the
notional amount of such Class of Certificates or Class X-D Components has been reduced to zero.

 

(ii)             Any Yield Maintenance Charge that is to be distributed to the Regular Certificates or Class X-D Components on any Distribution
Date shall be deemed 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 and Class X-D Components (in the same order as distributions are made
pursuant to Section 4.01(b) of

 

    	-236-

    	 

    

 

this Agreement) up to an amount equal to all amounts remaining due and payable on the
Regular Certificates and the Class X-D Components in accordance with Section 4.01(b) of this Agreement, 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 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 Principal Balance of the Class of Corresponding Certificates that will be outstanding immediately
following such Distribution Date.

 

(f)              The Certificate Principal 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 Regular Certificates in the following order, until the Certificate Principal Balance of each such Class of Certificates is reduced
to zero; first, to the Class NR Certificates; second, to the Class G Certificates; third, to the
Class F Certificates; fourth, to the Class E Certificates; fifth, to the Class D Certificates; sixth,
to the Class C Certificates; seventh, to the Class B Certificates; eighth, to the Class A-S Certificates; and, finally,
pro rata 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-SB Certificates based on their respective Certificate Principal
Balances. Any amounts recovered in respect of any amounts previously written off as Realized Losses will be distributed to the
Classes of Certificates to which Realized Losses have been allocated in order of their seniority and shall be deemed to be distributed
to the Corresponding Lower-Tier Regular Interests. 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 Principal Balance of the Class of
Certificates in respect of which any such reimbursement is made. To the extent 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 Prepayment Period during which the recovery occurred) the amount of such recovery will
be added to the Certificate Principal Balance of the Class or Classes of Regular Certificates (other than the Class X Certificates)
that previously were allocated Realized Losses,

 

    	-237-

    	 

    

 

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 Regular Certificates had never been written
down (and, to the extent that the Certificate Principal Balance of, and 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 Principal Balance of any Class of Regular Certificates (other
than the Class X Certificates) (or the Lower-Tier Principal Balance of any Lower-Tier Regular Interest) is so increased, the
amount of unreimbursed 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 will be reduced to reflect reductions of the Certificate Principal Balance of the Class A-1, Class A-2,
Class A-3, Class A-4, Class A-SB and Class A-S Certificates resulting from allocations of Realized Losses. The Notional
Amount of the Class X-B Certificates will be reduced to reflect reductions of the Certificate Principal Balance of the Class B
Certificates resulting from allocations of Realized Losses. The Notional Amount of the Class X-D Certificates will be reduced to
reflect reductions of the Notional Amount of the Class D Component and Class E Component. The Notional Amount of the Class D Component
will be reduced to reflect reductions in the Certificate Principal Balance of the Class D Certificates resulting from allocation
of Realized Losses. The Notional Amount of the Class E Component will be reduced to reflect reductions in the Certificate Principal
Balance of the Class E Certificates resulting from allocation of Realized Losses. The Notional Amount of the Class X-F Certificates
will be reduced to reflect reductions of the Certificate Principal Balance of the Class F Certificates resulting from allocations
of Realized Losses. The Notional Amount of the Class X-G Certificates will be reduced to reflect reductions of the Certificate
Principal Balance of the Class G Certificates resulting from allocations of Realized Losses. The Notional Amount of the Class
X-NR Certificates will be reduced to reflect reductions of the Certificate Principal Balance of the Class NR Certificates
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
on each Distribution Date other than the Termination Date to each Certificateholder of record on the related Record Date
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity
located in the United States and having appropriate facilities therefor, if such Certificateholder provides the Certificate
Administrator with wiring instructions no less than five (5) Business Days prior to the related Record Date, or otherwise
(b) by check mailed to such Certificateholder. The final distribution on each Certificate shall be made in like manner,
but only upon presentment and surrender of such Certificate at the office of the Certificate Administrator or its agent
(which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice to
Certificateholders of such final distribution. The

 

    	-238-

    	 

    

 

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

 

(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 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. 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 to the extent permitted by law, 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

 

    	-239-

    	 

    

 

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)              [Reserved]

 

(j)              The Excess Prepayment Interest Shortfall, if any, for each Distribution Date will be allocated among the various Classes
of Regular Certificates and Class X-D Components, pro rata, based upon the respective Interest Accrual Amounts with respect
to such Classes of Regular Certificates and Class X-D Components 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 Component, as applicable.

Notwithstanding the foregoing,

Notwithstanding the foregoing,
if the Controlling Class Representative or any Controlling Class Certificateholder is a Borrower Party with respect to any Excluded
Controlling

 

    	-245-

    	 

    

 

Class Loan, such Person shall not have access to any Excluded Information on the Certificate Administrator’s

Any Person that is a

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-1D hereto certifying
to the effect that it is an Excluded Controlling Class Holder, all information (other than Excluded Information related to the
Excluded Controlling Class 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 conclusively 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 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 Loan(s)
set forth in that Investor Certification. In the event the Controlling Class Representative or a Controlling Class Certificateholder
becomes an Excluded Controlling Class Holder, such Controlling Class Representative or Controlling Class Certificateholder 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-1D to the effect that such party is an Excluded Controlling Class
Holder and identify the Excluded Controlling Class Loan(s) and thereafter, upon submission of Exhibit M-1E, shall not be
entitled to any Excluded Information 

 

    	-246-

    	 

    

 

related to such Excluded Controlling Class Loan(s) and made available on the Certificate Administrator’s Website. In addition
to sending Exhibit M-1D to each of the parties hereto, any Excluded Controlling Class Holder shall also send to the Certificate
Administrator a notice substantially in the form of Exhibit M-1F hereto, which such notice shall provide each of the CTSLink
User ID associated with such Excluded Controlling Class Holder, and which such notice shall direct 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. Any Excluded Information relating to an Excluded Controlling Class 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 pursuant to Section 3.32, in
one or more separate files labeled “Excluded Controlling Class Loan” followed by the applicable loan name and loan
number, and the Certificate Administrator shall segregate on the Certificate Administrator’s Website such Excluded Information
from information relating to other Mortgage Loans. 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 Loan (including,
in the case of an Asset Status Report or 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 and to the extent
a Control Termination Event and/or a Consultation Termination Event had occurred with respect to such Excluded Loan, the Controlling
Class Holder will be entitled to notify each of the parties hereto that it is no longer an Excluded Controlling Class Holder and
a Control Termination Event and/or a Consultation Termination Event has ceased to occur with respect to the Excluded Loan. To
the extent the Controlling Class Representative or a Controlling Class Certificateholder receives access pursuant to this Agreement
to any Excluded Information on the Certificate Administrator’s Website or otherwise receives access to such Excluded Information,
such 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 Loan to the related Mortgagor or to any
Excluded Controlling Class Holder or (A) any employees or personnel of such Controlling Class Representative or Controlling Class
Certificateholder or any Affiliate involved in the management of any investment in the related Mortgagor or the related Mortgaged 

 

    	-247-

    	 

    

 

Property or (B) to its actual knowledge, any non-Affiliate that holds a direct or indirect ownership interest in the related Mortgagor,
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.

 

The Certificate Administrator,
the Master Servicer and the Special Servicer 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.

 

(b)            The Certificate Administrator makes no representations or warranties as to the accuracy or completeness of information provided
pursuant to this Section and assumes no responsibility therefor. In addition, the Certificate Administrator disclaims responsibility
for any information distributed by the Certificate Administrator for which it is not the original source. The Certificate Administrator
shall have no obligation to recompute, recalculate or otherwise verify any information provided to it by the Master Servicer or
the Special Servicer. 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. The Certificate
Administrator shall provide assistance in using the Certificate Administrator’s Website through the Certificate Administrator’s
customer service desk at telephone number (866) 846-4526. Notwithstanding anything herein to the contrary, the Certificate Administrator,
the Master Servicer and the Special Servicer shall not be liable for any disclosure of Excluded Information relating to an Excluded
Controlling Class Loan to the extent such information was included in the Asset Status Report or the 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 Loan or not properly delivered pursuant to Section 3.32.

 

The Certificate Administrator
may provide such information through means other than (and in lieu of) the Certificate Administrator’s Website; provided
that (i) the Depositor shall have consented to such alternative means and (ii) Certificateholders and each of the Companion
Loan Holders shall have received notice of such alternative means (which notice may be given via the Certificate Administrator’s
Website).

 

Any Person that is a
Mortgagor, a Manager of a Mortgaged Property, an Affiliate of the foregoing, or an agent of any Mortgagor shall be entitled to
access only the Prospectus Supplement, Distribution Date Statements, this Agreement, the Loan Purchase Agreements and the Commission
EDGAR filings on the Certificate Administrator’s Website which are being made available to the general public. The provisions
in this Section shall not limit the Master Servicer’s ability to make accessible certain information regarding the Mortgage
Loans at a website maintained by the Master Servicer.

Within a reasonable period
of time after the end of each calendar year, the Certificate Administrator shall furnish to each Person who at any time during
the calendar year was a Holder of a Certificate a statement containing the information 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 determines to be necessary 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 Beneficial Owners may (i)(a) submit
questions to the Certificate Administrator relating to the Distribution Date Statement, (b) submit questions to 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 (or Serviced Whole Loans) or the Mortgaged Properties and (c) submit
questions to the Operating Advisor 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
(collectively, “Inquiries”), and (ii) 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,
the Certificate Administrator shall forward the Inquiry to the Operating Advisor, the Master Servicer or the Special Servicer,
as applicable, 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.
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 not of a type described above, (ii) answering any Inquiry (A) would not be in the best interests of the Trust
and/or the Certificateholders, (B) would be in violation of applicable law, this Agreement or the applicable Mortgage Loan
Documents, (C) 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, or (D) would reasonably
be expected to result in the waiver of an attorney client privilege or the disclosure of attorney work product or (iii) it
is otherwise, for any reason, not advisable to answer, 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. The Certificate
Administrator shall notify the Person who submitted such Inquiry in the event that the Inquiry will not be answered. The

 

    	-249-

    	 

    

 

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 no other Person will certify
as to the accuracy, or 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 Beneficial 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 Beneficial Owners can register and thereafter obtain information with respect to any other Certificateholder or Beneficial
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 Beneficial 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 Beneficial 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 Beneficial 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.

 

Upon filing with the
IRS, the Certificate Administrator shall furnish to the Holders of the Class R Certificates the IRS Form 1066 for each Trust
REMIC and shall furnish their respective Schedules Q thereto at the times required by the Code or the IRS, and shall provide from
time to time such information and computations with respect to the entries on such forms as any Holder of the 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 Beneficial
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

 

    	-250-

    	 

    

 

(such other information, collectively, “Additional Information”) with
respect to the Mortgage Loans or Serviced Whole Loans, 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 made in writing.

authorizes the Certificate Administrator to, and the Certificate Administrator shall (to the extent received by the Certificate
Administrator), make available to Bloomberg Financial Markets, L.P., Trepp, LLC, Intex Solutions, Inc., BlackRock Financial Management,
Inc. or such other vendor chosen by the Depositor that submits to the Certificate Administrator a certification in the form of

In addition, the Master

to a Specially Serviced Loan that is not, and a REO Property that does not relate to, a Non-Serviced Mortgage Loan), as applicable,

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 non-Specially Serviced Loans) or Special Servicer (with respect to Specially Serviced Loans and REO Properties), as

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

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 and other payees of interest or original issue discount that the Paying Agent reasonably
believes are applicable under the Code. The consent of Certificateholders or payees 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 or payee pursuant to federal withholding requirements, the Paying Agent shall indicate the amount withheld
to such Certificateholder or payee. Any amount so withheld shall be treated as having been distributed to such Person for all purposes
of this Agreement.

 

(b)            Each Beneficial Owner and Certificateholder, by the purchase of a Certificate or its acceptance of a beneficial interest
therein, acknowledges that interest on the Certificates will be treated as United States source interest, and, as such, United
States withholding tax may apply. Each such Beneficial Owner and Certificateholder further agrees, upon request, to provide any
certifications that may be required under applicable law, regulations or procedures to evidence its status for United States withholding
tax purposes and understands that if it ceases to satisfy the foregoing requirements or provide requested documentation, payments
to it under the Certificates may be subject to United States withholding tax (without any corresponding gross-up). Without limiting
the foregoing, if a payment made under this Agreement would be subject to United States federal withholding tax imposed by FATCA
if the recipient of such payment were to fail to comply with FATCA (including the requirements of 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.

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

for its first taxable year ending December 31, 2015, in accordance with the REMIC Provisions; (iii) prepare and forward, or
cause to be prepared and forwarded, to the Certificateholders 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). 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 hereof, 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 Administrator in connection with any audit or administrative or judicial
proceeding shall be paid by the Trust Fund.

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 either Trust REMIC or the imposition of tax on either 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 either 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 either 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.

 

(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.

 

    	-257-

    	 

    

 

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

 

Section 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 either Trust REMIC, such tax shall be charged against amounts otherwise distributable
to Certificateholders; 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 either 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 either 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 either 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, provided, further, that such breach, act or omission could result in liability under
Section 6.03, in the case of the

 

    	-258-

    	 

    

 

Master
Servicer or the Special Servicer, as applicable, or Section 4.04 or 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 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 in the Prepayment Period
relating to such Distribution Date (or, in the case of a Non-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 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; and

 

(iv)            make a P&I Advance by remittance to the Certificate Administrator for deposit into the Lower-Tier 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 Whole Loan, but not a Companion Loan) to the extent such amounts were not received on such Mortgage
Loan as of the close of business on the immediately preceding Due Date (without regard to any grace period) (and which delinquent
payment has not been cured as of 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®.

 

Neither the Master Servicer
nor the Trustee shall be required or permitted to make an advance for Balloon Payments, Default Interest or Yield Maintenance Charges
or delinquent

 

    	-259-

    	 

    

 

monthly
payments on any Companion Loan. The amount of interest required to be advanced in respect of payments of delinquent interest on
any Mortgage Loan as to which an Appraisal Reduction Amount exists will equal (i) the amount of interest required to be advanced
by the Master Servicer without giving effect to such Appraisal Reduction Amount less (ii) an amount equal to the product
of (x) the amount otherwise required to be advanced by the Master Servicer with respect to such delinquent payment of interest
without giving effect to such Appraisal Reduction Amounts, and (y) a fraction, the numerator of which is the Appraisal Reduction
Amount with respect to such Mortgage Loan 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.

 

To the extent required
under the related Co-Lender Agreement, if a P&I Advance is made with respect to any Mortgage Loan with a related Serviced Companion
Loan, the Master Servicer or Trustee shall notify the Other Master Servicer and the Other Trustee of the amount of P&I Advance
made with respect to such Mortgage Loan within two (2) Business Days of making such P&I Advance.

 

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 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 permitted 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, the Special Servicer or the Trustee 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 Master Servicer, the Special 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 accordance
with its good faith business judgment, and, shall be evidenced by an Officer’s Certificate as set forth in Section 4.06(b).
In making such recoverability determination, such Person will be entitled to consider (among other things) the
obligations of the Mortgagor under the terms of the related Mortgage Loan or Whole Loan as it may have been modified, to consider
(among other

 

    	-260-

    	 

    

 

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

 

The determination by
the Master Servicer 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 conclusive
and binding on the Master Servicer (in the case of such a determination by the Special Servicer) and the Trustee; provided
that this sentence 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 P&I Advance constitutes or would constitute
a Nonrecoverable Advance. 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, makes a determination
prior to the times specified in this Section 4.06 that such advance would be a Nonrecoverable Advance.

 

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.

 

With respect to P&I
Advances and any Non-Serviced Mortgage Loan, the Master Servicer and the Trustee shall be entitled to rely on the “appraisal
reduction amount” calculated by the related Other Special Servicer or the related Other Master Servicer in accordance with
the terms of the applicable Other Pooling and 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 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

 

    	-261-

    	 

    

 

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 (12) 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.

 

With respect to each
Whole Loan, if the Master Servicer, Special Servicer or Trustee has determined that a P&I Advance with respect to such Mortgage
Loan, would be or has become a Nonrecoverable Advance, the Master Servicer shall provide each Other Master Servicer, Other Special
Servicer and Other Trustee written notice of such determination together with such reports that the Master Servicer delivered to
the Special Servicer or Trustee in connection with notification of its determination of nonrecoverability within the time period
required by the related Co-Lender Agreement.

 

(c)             With respect to any Non-Serviced Mortgage Loan, if (1) the related Other Master Servicer has determined that a proposed
P&I Advance (as defined in the applicable Other Pooling and Servicing Agreement) with respect to a Non-Serviced Mortgage
Loan, if made, or any outstanding P&I advance previously made, would be, or is, as applicable, a “nonrecoverable advance,”
and the related Other Master 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 a Non-Serviced Mortgage 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 Non-Serviced Mortgage Loan until the Master Servicer or the Special Servicer, as applicable, has consulted
with the related Other Master Servicer under the applicable Other Pooling and Servicing Agreement and they agree that circumstances
with respect to such Mortgage Loans have changed such that a proposed future P&I Advance would not be a “nonrecoverable
advance.”

 

In connection with any
Non-Serviced Mortgage Loan, any determination by the Master Servicer for such Non-Serviced Mortgage Loan that any P&I Advance
made or to be made with respect to such Non-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 by the related Companion Loan Holder regarding nonrecoverability of debt service advances on the related Non-Serviced
Companion Loan.

 

(d)            If the Trustee, the Master Servicer or the Special Servicer has received written notice from Moody’s, Fitch, KBRA
or Morningstar 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, KBRA or

 

    	-262-

    	 

    

 

Morningstar, 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 applicable Companion Loan Holder and the applicable master servicer
of any Companion Loan.

Certificate Registrar, be necessary, appropriate or convenient to comply, or facilitate compliance, with applicable laws, and may
have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required
by law, or as may, consistently herewith, be determined by the officers executing such Certificates, as evidenced by their execution
thereof.

 

(a)             The Public Certificates (other than the Class X-A and Class X-B Certificates) shall be issued in minimum denominations of
$10,000 and integral multiples of $1 in excess thereof. The Private Certificates (other than the Class X-D, Class X-F, Class X-G,
Class X-NR and Class R Certificates) shall be issued in minimum denominations of $100,000 and integral multiples of $1 in

maintained and transferred only in minimum denominations of authorized initial notional amounts of not less than $1,000,000 and
in integral multiples of $1 in excess thereof. If the initial Certificate Principal Balance or initial Notional Amount, as applicable,
of any Class of Regular Certificates does not equal an integral multiple of $1, then a single additional Certificate of such Class
may be issued in a minimum denomination of authorized initial Certificate Principal Balance or initial Notional Amount, as applicable,
that includes the excess of (i) the initial Certificate Principal Balance or initial Notional Amount, as applicable, of such

(b)            One authorized signatory shall sign the Certificates for the Certificate Administrator by manual or fax signature. If an
authorized signatory whose signature is on a

 

    	-263-

    	 

    

 

Certificate
no longer holds that office at the time the Certificate Administrator 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 interest coupons, substantially in the applicable form set forth as an exhibit hereto, which shall be deposited with the
Certificate Registrar or an agent of the Certificate Registrar, as custodian for the Depository, and registered in the name of
the Depository or a nominee of the Depository. The aggregate Certificate Principal Balance of a 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.

 

(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 Class R Certificates) sold in offshore transactions
in reliance on Regulation S under the Securities Act shall initially be represented by a temporary global certificate in definitive,
fully registered form without interest coupons, substantially in the applicable form set forth as an exhibit hereto (each a “Temporary
Regulation S 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

 

    	-264-

    	 

    

 

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 Principal 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.

 

(ii)           The Certificates of each Class of Private Certificates (other than 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 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
Principal 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 and the Class R Certificates (collectively, the “Non-Book
Entry Certificates”) shall be in the form of Definitive Certificates, substantially in the applicable form set forth
as an exhibit hereto, and shall be registered in the name of such investors or their nominees by the Certificate Registrar who
shall deliver the certificates for such Non-Book Entry Certificates to the respective beneficial owners or owners.

 

(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 Beneficial 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 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.

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 of the same Class, such holder may, subject to the rules and procedures of the
Depository, exchange or cause the exchange of such interest for an equivalent beneficial interest in such Temporary
Regulation S Global Certificate. Upon receipt by the Certificate Registrar, as registrar, at its office designated in Section
5.11 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

to be exchanged, (2) a written order given in accordance with the Depository’s procedures containing information
regarding the Euroclear or Clearstream account to be credited with such increase and the name of such account and (3) a
certificate in the form of Exhibit E to this Agreement given by the holder of such beneficial interest stating

Certificate by the aggregate Certificate Principal 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 Principal 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

 

    	-267-

    	 

    
 

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 directing the Certificate
Registrar to credit or cause to be credited a beneficial interest in the Regulation S Global Certificate in an amount equal

of the Regulation S Global Certificate by the aggregate Certificate Principal Balance of the beneficial interest in the Rule 144A
Global Certificate to be exchanged, to credit or cause to be credited to the account of the Person specified in such instructions
a beneficial interest in the Regulation S Global Certificate equal to the reduction in the Certificate Principal Balance
of the Rule 144A Global Certificate, and to debit, or cause to be debited, from the account of the Person making such exchange
or transfer the beneficial interest in the Rule 144A Global Certificate that is being exchanged or transferred.

 

(e)            Temporary Regulation S Global Certificate or Regulation S Global Certificate to Rule 144A Global Certificate.
If a holder of a beneficial interest in a Temporary Regulation S Global Certificate or Regulation S Global Certificate
deposited with the Certificate Registrar as custodian for the Depository wishes at any time to exchange its interest in such Temporary
Regulation S Global Certificate or Regulation S Global Certificate for an interest in the Rule 144A Global Certificate
of the same Class, or to transfer its interest in such Temporary Regulation S Global Certificate or Regulation S Global
Certificate to a Person who is required to take delivery thereof in the form of an interest in the Rule 144A Global Certificate,
such holder may, subject to the rules and procedures of Euroclear or Clearstream, as the case may be, and the Depository, exchange
or cause the exchange of such interest for an equivalent beneficial interest in the Rule 144A Global Certificate of the same
Class. Upon receipt by the Certificate Registrar, as registrar, at its office designated in Section 5.11 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 regarding the participant account with the Depository to be credited with such increase, (2) with respect
to a transfer of an interest in the Regulation S Global Certificate, information regarding the participant account of the
Depository to be debited with such decrease and (3) with respect to a transfer of an interest in the Temporary Regulation S
Global Certificate (but not the Regulation S Global Certificate) for an interest in the Rule 144A Global Certificate
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

 

    	-268-

    	 

    

 

Certificate Principal Balance of the Temporary Regulation S
Global Certificate or Regulation S Global Certificate and to increase, or cause to be increased, the Certificate Principal
Balance of the Rule 144A Global Certificate by the aggregate Certificate Principal 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
Principal 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 or 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
and authenticated Regulation S Global Certificate, representing the aggregate Certificate Principal 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 Principal 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 a Class R Certificate) wishes at any time to exchange its interest in such Non-Book Entry Certificate for an interest
in a Global Certificate of the same Class, or to transfer all or part of such Non-Book Entry Certificate to a Person who is entitled
to take delivery thereof in the form of an interest in a Global Certificate, such holder may, subject to the rules and procedures
of Euroclear or Clearstream, if applicable, and the Depository, cause the exchange of all or part of such Non-Book Entry Certificate
for an equivalent beneficial interest in the appropriate Global Certificate of the same Class. Upon receipt by the Certificate
Registrar, as registrar, at its office designated in Section 5.11 of this

 

    	-269-

    	 

    

 

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 Principal
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 Principal 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 Principal Balance of
the portion of the Non-Book Entry Certificate to be exchanged and to credit, or cause to be credited, to the account of the Person
specified in such instructions a beneficial interest in the applicable Global Certificate equal to the Certificate Principal Balance
of the portion of the Non-Book Entry Certificate so canceled.

 

(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 the Certificate Registrar shall refuse to register such
transfer unless it receives (and upon receipt, may conclusively rely upon): (i) an investment representation letter from the
proposed transferee substantially in the form attached as Exhibit L-4 to this Agreement and (ii) 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)             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) and (h) above (including
the certification requirements intended to ensure that such transfers comply with Rule 144A or Regulation S under the
Securities Act, at the case may be) and such other procedures as may from time to time be adopted by the Certificate Registrar.

 

(j)             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

 

    	-270-

    	 

    

 

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.

 

(k)            [Reserved]

 

(l)             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.

 

(m)           No ERISA Restricted Certificate or Class R Certificate may be purchased by or transferred to any prospective purchaser
or transferee that is or will be an employee benefit plan or other plan subject to the fiduciary responsibility or prohibited transaction
provisions of ERISA or Code Section 4975 or a governmental plan (as defined in Section 3(32) of ERISA) or other plan
that is subject to any federal, state or local law that is, to a material extent, similar to the foregoing provisions of ERISA
or the Code (“Similar Law”) (each, a “Plan”), or any person acting on behalf of any such
Plan or using the assets of a Plan (within the meaning of 29 C.F.R. Section 2510.3 101, as modified by Section 3(42) of ERISA,
or of applicable Similar Law) to purchase such ERISA Restricted Certificate or Class R Certificate, other than, in the case
of the ERISA Restricted Certificates, an insurance company using the assets of its general account under circumstances whereby
the purchase and holding of such Certificates by such insurance company would be exempt from the prohibited transaction provisions
of ERISA and the Code under Sections I and III of Prohibited Transaction Class Exemption 95-60 (or a Plan subject to
Similar Law where the purchase and holding of such Certificates by such Plan would not constitute a non-exempt violation of Similar
Law). Except in connection with the transfer thereof by an Initial Purchaser or the Depositor, each prospective transferee of an
ERISA Restricted Certificate or Class R Certificate in Non-Book Entry Certificate form shall deliver to the transferor, the
Depositor, the Certificate Registrar, the Certificate Administrator and the Trustee a representation letter, substantially in the
form of Exhibit L-3 to this Agreement, stating that the prospective transferee is not a Plan or a person acting on
behalf of or using the assets of a Plan (within the meaning of 29 C.F.R. Section 2510.3 101, as modified by Section 3(42) of ERISA,
or of applicable Similar Law), other than, in the case of the ERISA Restricted Certificates, an insurance company using the assets
of its general account under circumstances whereby the purchase and holding of such Certificates by such insurance company would
be exempt from the prohibited transaction provisions of ERISA and the Code under Sections I and III of Prohibited Transaction Class Exemption 95-60
(or a Plan subject to Similar Law where the purchase and holding of such Certificates by such Plan would not constitute a non-exempt
violation of Similar Law). No Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A,
Class X-B, Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D or Class E Certificate
and no Certificate which has ceased to be an ERISA Restricted Certificate (because of the proviso in the definition of “ERISA
Restricted Certificate”) may be purchased by or transferred to any prospective purchaser or transferee that is or will be
a Plan, or any person acting on behalf of any such Plan or using the assets of a Plan (within the meaning of 29 C.F.R. Section
2510.3-101, as modified by Section 3(42) of ERISA, or of applicable Similar Law) to purchase such Certificate, unless (A) the
purchaser is an “accredited investor” within the meaning of Rule 501(a)(1) of the Securities Act and (B) the acquisition,
holding and disposition of such Certificate by the purchaser will not constitute or otherwise result in a non-exempt prohibited
transaction under ERISA or Code Section 4975 (or a similar

 

    	-271-

    	 

    

 

non-exempt violation of Similar Law). Any attempted or purported
transfer in violation of these transfer restrictions shall be null and void ab initio and shall vest no rights in any purported
transferee and shall not relieve the transferor of any obligations with respect to the applicable Certificates.

 

(n)            Each Person who has or acquires any Residual Ownership Interest shall be deemed by the acceptance or acquisition of such
Residual Ownership Interest to have agreed to be bound by the following provisions and the rights of each Person acquiring any
Residual Ownership Interest are expressly subject to the following provisions:

 

(i)             Each Person acquiring or holding any Residual Ownership Interest shall be a Permitted Transferee and shall not acquire or
hold such Residual Ownership Interest as agent (including a broker, nominee or other middleman) on behalf of any Person that is
not a Permitted Transferee. Any such Person shall promptly notify the Certificate Registrar of any change or impending change in
its status (or the status of the beneficial owner of such Residual Ownership Interest) as a Permitted Transferee. Any acquisition
described in the first sentence of this Section 5.03(n) by a Person who is not a Permitted Transferee or by a Person who
is acting as an agent of a Person who is not a Permitted Transferee shall be void ab initio and of no effect, and the immediately
preceding owner who was a Permitted Transferee shall be restored to registered and beneficial ownership of the Residual Ownership
Interest as soon and as fully as possible.

 

(ii)            No Residual Ownership Interest may be Transferred, and no such Transfer shall be registered in the Certificate Register,
without the express written consent of the Certificate Registrar, and the Certificate Registrar shall not recognize the Transfer,
and such proposed Transfer shall not be effective, without such consent with respect thereto. In connection with any proposed Transfer
of any Residual Ownership Interest, the Certificate Registrar shall, as a condition to such consent, (x) require the proposed
transferee to deliver, and the proposed transferee shall deliver to the Certificate Registrar and to the proposed transferor, an
affidavit in substantially the form attached as Exhibit L-1 to this Agreement (a “Transferee Affidavit”)
of the proposed transferee (A) that such proposed transferee is a Permitted Transferee and (B) stating that (1) the proposed
transferee historically has paid its debts as they have come due and intends to do so in the future, (2) the proposed transferee
understands that, as the holder of a Residual Ownership Interest, it may incur tax liabilities in excess of cash flows generated
by the residual interest, (3) the proposed transferee intends to pay taxes associated with holding the Residual Ownership Interest
as they become due, (4) the proposed transferee will not cause income with respect to the Residual Ownership Interest to be attributable
to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of such proposed transferee
or any other U.S. Tax Person, (5) the proposed transferee will not transfer the Residual Ownership Interest to any Person that
does not provide a Transferee Affidavit or as to which the proposed transferee has actual knowledge that such Person is not a Permitted
Transferee or is acting as an agent (including a broker, nominee or other middleman) for a Person that is not a Permitted Transferee,
and (6) the proposed transferee expressly agrees to be bound by and to comply with the provisions of this Section 5.03(n)
and (y) other than in connection with the initial issuance of a Class R Certificate or the Transfer of any Class R Certificate
by

 

    	-272-

    	 

    

 

any Initial Purchaser in connection with the initial offering of the Certificates, require a statement from the proposed transferor
substantially in the form attached as Exhibit L-2 to this Agreement (the “Transferor Letter”), that
the proposed transferor has no actual knowledge that the proposed transferee is not a Permitted Transferee and has no actual knowledge
or reason to know that the proposed transferee’s statements in the Transferee Affidavit are false.

 

(iii)           Notwithstanding the delivery of a Transferee Affidavit by a proposed transferee under clause (n)(ii) above,
if a Responsible Officer of the Certificate Registrar has actual knowledge that the proposed transferee is not a Permitted Transferee,
no Transfer to such proposed transferee shall be effected and such proposed Transfer shall not be registered on the Certificate
Register; provided, however, that the Certificate Registrar shall not be required to conduct any independent investigation
to determine whether a proposed transferee is a Permitted Transferee. Upon notice to the Certificate Registrar that there has occurred
a Transfer to any Person that is a Disqualified Organization or an agent thereof (including a broker, nominee or middleman) in
contravention of the foregoing restrictions, and in any event not later than 60 days after a request for information from
the transferor of such Residual Ownership Interest or such agent, the Certificate Registrar and the Certificate Administrator agree
to furnish to the IRS and the transferor of such Residual Ownership Interest or such agent such information necessary to the application
of Code Section 860E(e) as may be required by the Code, including, but not limited to, the present value of the total
anticipated excess inclusions with respect to such Class R Certificate (or portion thereof) for periods after such Transfer. At
the election of the Certificate Registrar, the Certificate Registrar may charge a reasonable fee for computing and furnishing such
information to the transferor or to such agent referred to above; provided, however, that such Persons shall in no
event be excused from furnishing such information.

 

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

 

Section 5.04     Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate
and (b) there is delivered to the Certificate Registrar, the Trustee and the Certificate Administrator such security or indemnity
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
in the Trust Fund. In connection with the issuance of any new Certificate under this Section 5.04, the Certificate Registrar
and the Certificate Administrator may require the payment of a sum sufficient to cover any expenses (including the fees and expenses
of the Certificate Registrar) connected therewith. Any replacement Certificate issued pursuant to this Section 5.04 shall
constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time.

Administrator and the Certificate Registrar, and any agent of any of them, may treat the Person in whose name any Certificate is
registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all
other purposes whatsoever, and neither the Master Servicer, the Special Servicer, the Operating Advisor, the Trustee, the Certificate
Registrar, nor any agent of any of them shall be affected by any notice to the contrary; provided, however, that
to the extent that a party to this Agreement responsible for distributing any report, statement or other information required to
be distributed to Certificateholders has been provided an Investor Certification, such party to this Agreement shall distribute
such report, statement or other information to such Beneficial Owner (or prospective transferee).

 

Section 5.06     Appointment of Paying Agent. The Certificate Administrator may appoint (and, if it does not so appoint, shall act
as) a paying agent for the purpose of making distributions to Certificateholders pursuant to Section 4.01 of this Agreement.
The Certificate Administrator shall cause such Paying Agent, if other than the Certificate Administrator or the Master Servicer,
to execute and deliver to the Master Servicer and the Certificate Administrator an instrument that is consistent in all material
respects with this Agreement and in which such Paying Agent shall agree with the Master Servicer and the Certificate Administrator
that such Paying Agent will hold all sums held by it for the payment to Certificateholders in trust for the benefit of the Certificateholders
entitled thereto until such sums have been paid to the Certificateholders or disposed of as otherwise provided herein. The initial
Paying Agent shall be the Certificate Administrator. The Paying Agent shall at all times (a) have a rating on its unsecured
long-term debt of at least “A2” by Moody’s and “A” by Fitch and (b) have a rating on its unsecured
short-term debt of at least “P-1” by Moody’s (or have such other rating with respect to which the Rating Agencies

Section 5.07     Access to Certificateholders’ Names and Addresses; Special Notices.

 

(a)           
If any Certifying Certificateholder, the Master Servicer or the Special Servicer (for purposes of this Section 5.07,
an “Applicant”) applies or requests in writing to the Certificate Registrar, and such application or request
states that the Applicant desires to communicate with the Certificateholders, the Certificate Registrar shall promptly furnish
or cause to be furnished to such Applicant a list of the names and addresses of the Certificateholders as of the most recent Record

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

 

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

 

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

 

(d)           
The Certificate Administrator or Certificate Registrar may require such additional proof of any matter referred to in this
Section 5.08 as it shall deem necessary.

 

Section 5.09     Authenticating Agent. The Certificate Administrator may appoint an Authenticating Agent to execute and to authenticate
Certificates. The Authenticating Agent must be acceptable to the Depositor and must be a corporation organized and doing business
under the laws of the United States of America or any state, having a principal office and place of business in a state and city
acceptable to the Depositor, having a combined capital and surplus of at least $15,000,000, authorized under such laws to do a

    	-275-

    	 

    

 

serve
as the initial Authenticating Agent and the Certificate Administrator hereby accepts such appointment.

 

Any corporation into
which the Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from
any merger, conversion or consolidation to which the Authenticating Agent shall be party, or any corporation succeeding to the
corporate agency business of the Authenticating Agent, shall be the Authenticating Agent without the execution or filing of any
paper or any further act on the part of the Certificate Administrator or the Authenticating Agent.

 

The Authenticating Agent
may at any time resign by giving at least 30 days’ advance written notice of resignation to the Certificate Administrator
and the Depositor. The Certificate Administrator may at any time terminate the agency of the Authenticating Agent by giving written
notice of termination to the Authenticating Agent and the Depositor. Upon receiving a notice of resignation or upon such a termination,
or in case at any time the Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section
5.09, the Certificate Administrator promptly shall appoint a successor Authenticating Agent, 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 Authenticating Agent shall be appointed unless
eligible under the provisions of this Section 5.09.

 

The Authenticating Agent
shall have no responsibility or liability for any action taken by it as such at the direction of the Certificate Administrator.
Any compensation paid to the Authenticating Agent shall be an unreimbursable expense of the Certificate Administrator. The appointment
of an Authenticating Agent 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 Authenticating Agent.

 

Section 5.10     Appointment of Custodian. The Certificate Administrator may appoint one or more Custodians to hold all or a portion
of the Mortgage Files as agent for the Certificate Administrator, 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 and to enforce the terms and provisions thereof against the Custodian for the benefit
of the Certificateholders and the Companion Loan Holders. Each Custodian shall be a depository institution subject to supervision
by federal or state authority, shall have a combined capital and surplus of at least $10,000,000, shall have a long-term debt rating
of at least “Baa1” by Moody’s, “BBB+” by Fitch and if rated by KBRA, a rating by KBRA at least equivalent
to “Baa1” by Moody’s, and shall be qualified to do business in the jurisdiction in which it holds any Mortgage
File. Each Custodial Agreement may be amended only as provided in Section 11.07 of this Agreement. Any compensation paid
to the Custodian shall be an unreimbursable expense of the Certificate Administrator. The Certificate Administrator shall serve
as the initial Custodian and shall be deemed appointed as Custodian at

 

    	-276-

    	 

    

 

all times that no other party is so appointed in accordance
with this Section 5.10. The Custodian, if the Custodian is not the Certificate Administrator, shall maintain a fidelity
bond 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. The Custodian 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 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 Certificate Administrator a Rating Agency Confirmation. 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     Maintenance of Office or Agency. The Certificate Registrar shall maintain or cause to be maintained an office or
offices or agency or agencies where Certificates may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Certificate Registrar in respect of the Certificates and this Agreement may be served. The Certificate
Registrar initially designates its office at Sixth Street & Marquette Avenue, Minneapolis, Minnesota 55479-0113 as its office
for such purposes. The Certificate Registrar shall give prompt written notice to the Certificateholders of any change in the location
of the Certificate Register or any such office or agency.

may be, or by reason of negligent disregard of the Master Servicer’s, the Special Servicer’s or the Operating Advisor’s,
as the case may be, obligations or duties hereunder, or (ii) as a result of the

  

    	-277-

    	 

    

 

 breach by the Master Servicer, the Special
Servicer or the Operating Advisor, as the case may be, of any of its representations or warranties contained herein. The Depositor

Section 6.02     Merger or Consolidation of the Master Servicer, the Special Servicer and the Operating Advisor. Subject to the following
paragraph, each of the Master Servicer, the Special Servicer and the Operating Advisor 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 to do business in each jurisdiction in which the
Mortgaged Properties are located, to the extent necessary to perform its obligations under this Agreement, or to protect the validity
and enforceability of this Agreement, 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 and the Operating Advisor 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 an operating
advisor or trust 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 or the Operating Advisor, as applicable, hereunder, and shall be deemed to have assumed all of the liabilities
of the Master Servicer, the Special Servicer or the Operating Advisor, as applicable, hereunder, if each of the Rating Agencies
has provided a Rating Agency Confirmation; provided that the Operating Advisor shall not be required to obtain a Rating
Agency Confirmation from any Rating Agency if the Operating Advisor is merged into or consolidated with an Eligible Operating Advisor
or transfers all or substantially all of its assets to an Eligible Operating Advisor; and provided, further, that
if the Master Servicer, the Special Servicer or the Operating Advisor enters into a merger and the Master Servicer, the Special
Servicer or the Operating Advisor, as applicable, is the surviving entity under applicable law, then the Master Servicer, the Special
Servicer or the Operating Advisor, as applicable, shall not, as a result of the merger, be required to provide a Rating Agency
Confirmation. Notwithstanding the foregoing, no Master Servicer, Special Servicer or Operating Advisor may remain the Master Servicer,
Special Servicer or Operating Advisor, as applicable, under this Agreement after (x) being merged or consolidated with or into
any Person that is a Prohibited Party, or (y) transferring all or substantially all of its assets to any Person if

 

    	-278-

    	 

    

 

such Person
is a Prohibited Party, except to the extent (i) the Master Servicer, the Special Servicer or Operating Advisor, as applicable,
is the surviving entity of such merger, consolidation or transfer and has been and continues to be in compliance with its Regulation
AB reporting obligations hereunder or (ii) the Depositor consents to such merger, consolidation or transfer, which consent shall
not be unreasonably withheld.

 

Section 6.03     Limitation on Liability of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and Others.
None of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor or any of the directors, members, managers,
officers, employees or agents of the Depositor, the Master Servicer, the Special Servicer or the Operating Advisor shall be under
any liability to the Trust, 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; provided,
however, that this provision shall not protect the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor
or any such Person against 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 and any director, member, manager, officer, employee or agent of the Depositor, the Master Servicer, the Special Servicer
or the Operating Advisor 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 and any director, member, manager, officer, employee or agent of the Depositor, the Master Servicer, the Special
Servicer or the Operating Advisor shall be indemnified and held harmless by the Trust (which indemnification amounts shall be payable
out of the Collection Account or the applicable Serviced Whole Loan Custodial Account if and to the extent with respect to a Serviced
Whole Loan and then out of the Collection Account, provided that, to the extent that the amount relates to a Serviced Whole
Loan, is required under the Co-Lender Agreement to be borne by the holder of a related Companion Loan and is paid from the Collection
Account because funds on deposit in the applicable Serviced Whole Loan 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 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 obligations or duties hereunder or by reason of negligent disregard of 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 or the Operating Advisor shall be under any obligation to appear
in, prosecute or defend any legal action unless such action is related to its

 

    	-279-

    	 

    

 

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; provided, however,
that any of the Depositor, the Master Servicer, the Special Servicer or the Operating Advisor 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 (payable
out of the Collection Account or the applicable Serviced Whole Loan Custodial Account if and to the extent with respect to a Serviced
Whole Loan and then out of the Collection Account, provided that to the extent that the amount relates to a Serviced Whole
Loan, is required under the related Co-Lender Agreement to be borne by the holder of a related Companion Loan and is paid from
the Collection Account because funds on deposit in the applicable Serviced Whole Loan 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 Companion Loan to deposit into the Collection Account the amount so paid from the Collection Account), and the Depositor,
the Master Servicer, the Special Servicer and the Operating Advisor shall be entitled to be reimbursed therefor from the Collection
Account or the applicable Serviced Whole Loan Custodial Account, as applicable, as provided in Section 3.06 and Section 3.06A
of this Agreement.

 

Each Other Securitization
Trust, Other Master Servicer, an Other Special Servicer, an Other Depositor, an Other Trustee, an Other Certificate Administrator,
an Other Operating Advisor, and any of their respective directors, officers, employees or agents (collectively, the “Other
Indemnified Parties”), shall be indemnified by the Trust and held harmless against the Trust’s pro rata
share (subject to the related Co-Lender Agreement) of any and all claims, losses, penalties, fines, forfeitures, legal fees and
related costs, judgments, and any other costs, liabilities, fees and expenses incurred in connection with the servicing and administration
of any Non-Serviced Mortgage Loan and the related Mortgaged Property under the related Other Pooling and Servicing Agreement (but
excluding any such losses allocable to any Non-Serviced Companion Loan), other than any losses incurred by reason of any Other
Indemnified Party’s willful misfeasance, bad faith or negligence in the performance of its obligations or duties or by reason
of negligent disregard of obligations and duties under the applicable Other Pooling and Servicing Agreement and to the extent amounts
on deposit in the “serviced whole loan custodial account” (or such other similar term, as defined in the applicable
Other Pooling and Servicing Agreement) are insufficient for reimbursement of such amounts, the Master Servicer shall, promptly
following notice from the related Other Master Servicer, reimburse each of such applicable Persons for the Trust’s pro
rata share of the insufficiency out of general funds in the Collection Account.

 

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

 

(a)           
Each of the Master Servicer, the Special Servicer and the Operating Advisor may assign its respective rights and delegate
its respective duties and obligations under this Agreement; provided that, with respect to any of the Master Servicer, the
Special Servicer or the Operating Advisor: (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

 

    	-280-

    	 

    

 

commercial mortgage loans (or,
in the case of the Operating Advisor, an Eligible Operating Advisor), 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 of an operating advisor, as applicable, or a Person resulting from a merger, consolidation or succession that
is permitted under Section 6.02 of this of this Agreement and, in the case of a Serviced Whole Loan, 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, the Special Servicer or the Operating Advisor, as the case may be, under this Agreement from
and after the date of such agreement; (ii) except in the case of a successor operating advisor that satisfies the requirements
of an Eligible Operating Advisor, each Rating Agency has delivered to the Trustee a Rating Agency Confirmation; (iii) the
Master Servicer, the Special Servicer or the Operating Advisor 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 Operating Advisor Fee, the Servicing Fee or Special Servicing Compensation, as applicable (or any component thereof) is
calculated shall not exceed the rate then in effect; and (v) the resigning Master Servicer, Special Servicer or Operating
Advisor, 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. Upon acceptance of such assignment and delegation, the purchaser or transferee
shall be the successor Master Servicer, Special Servicer or Operating Advisor, as applicable, hereunder.

 

(b)          
Except as provided in this Section 6.04 and Section 7.06(e), and subject to the following paragraph, the Master
Servicer, the Special Servicer and the Operating Advisor 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, the Special Servicer or the Operating
Advisor upon determination that such duties hereunder are no longer permissible under applicable law, the Trustee 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, Special Servicer or Operating Advisor, as applicable, as though the Master
Servicer, the Special Servicer or the Operating Advisor, as the case may be, had received a notice of termination. Any such determination
permitting the resignation of the Master Servicer, the Special Servicer or Operating Advisor, as applicable, shall be evidenced
by an Opinion of Counsel (obtained at the resigning Master Servicer’s, Special Servicer’s or Operating Advisor’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 or the Operating Advisor
as contemplated herein (except in circumstances where no successor Operating Advisor is required to be appointed) shall become
effective until the Trustee or a successor Master Servicer, Special Servicer or Operating Advisor shall have assumed the Master
Servicer’s, the Special Servicer’s or the Operating Advisor’s, as applicable, responsibilities, duties, liabilities
and obligations hereunder. If no successor Master Servicer, Special Servicer or Operating Advisor can be obtained to perform such
obligations for the same compensation to which the terminated Master

 

    	-281-

    	 

    

 

Servicer, Special Servicer or Operating Advisor would have
been entitled, additional amounts payable to such successor Master Servicer, Special Servicer or Operating Advisor shall be treated
as a shortfall resulting in Realized Losses; 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, and will only be permitted to appoint
such successor Master Servicer, Special Servicer or Operating Advisor at the direction of the Depositor.

 

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.

 

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 11.13 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 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 indemnified and reimbursed by the Trust 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 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 neither 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

 

    	-282-

    	 

    

 

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,
Beneficial 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 Beneficial 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 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 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 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.

 

    	-283-

    	 

    

 

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 Without Cause.

 

(a)           
At any time prior to the occurrence and continuance of any Control Termination Event, subject to Section 6.08(i)
of this Agreement, the Controlling Class Representative shall be entitled to terminate the rights (subject to Section 3.12
and Section 6.03 of this Agreement) and obligations of the Special Servicer under this Agreement (exclusive of any Excluded
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 Whole Loan,
the related Companion Loan Holder. Upon a termination (pursuant to the prior sentence) or a resignation (pursuant to Section
6.04(b) of this Agreement) of the Special Servicer, subject to Section 6.08(i) of this Agreement, the Controlling Class
Representative shall appoint a successor Special Servicer; provided, however, that (i) such successor will meet
the requirements set forth in Section 7.02 of this Agreement, (ii) the Controlling Class Representative 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 Whole Loan, the Controlling Class Representative shall (at no expense to the Trust or the related Other
Securitization Trust) obtain and deliver to the certificate administrator (if any) and the trustee for the related Other Securitization
Trust (with a 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 the related Companion Loan.

 

Following the occurrence
and during the continuance of a Control Termination Event, and subject to Section 6.08(i) of this Agreement upon (i) the
written direction of Holders of Certificates (other than the Class R Certificates) evidencing not less than 25% of the Voting
Rights of the Certificates requesting a vote to terminate and replace the Special Servicer 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
thereof to all Certificateholders by posting such notice on its internet website and by mailing at their addresses appearing in
the Certificate Register. Upon the written direction of (a) Holders of Regular Certificates evidencing at least 66 2/3% of
a Certificateholder Quorum or (b) Holders of Non-Reduced Certificates evidencing more than 50% of the Voting Rights of each
of Class of Non-Reduced Certificates, (subject to Section 6.08(i) of this Agreement), the Trustee shall terminate all of
the rights (subject to Section 3.12, Section 6.03 and Section 6.08(i) of this Agreement) and obligations of
the Special Servicer under this Agreement, and the proposed successor Special Servicer shall succeed to the duties of the Special
Servicer as if a removal and replacement were occurring pursuant to Section 7.01 and Section 7.02 of this Agreement;
provided that if such written direction is not provided within

 

    	-284-

    	 

    

 

180 days of the initial request for a vote to terminate
and replace the Special Servicer, then such written direction shall have no force and effect. The provisions set forth in the foregoing
sentences of this Section 6.08(a) 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 Beneficial Owner may access notices
on the Certificate Administrator’s Website and each Certificateholder and Beneficial 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)            At any time after the occurrence and during the continuance of a Consultation Termination Event and subject to Section
6.08(i) of this Agreement, if the Operating Advisor determines that the Special Servicer is not performing its duties as required
hereunder or is otherwise not acting in accordance with the Servicing Standard, the Operating Advisor shall deliver to the Trustee
and the Certificate Administrator, with a copy to the Special Servicer, a written 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) and
recommending a replacement special servicer meeting the applicable requirements of this Agreement, which recommended special servicer
has agreed to succeed as Special Servicer if appointed in accordance herewith. In such event, the Certificate Administrator shall
promptly post a copy of such recommendation on the Certificate Administrator’s Website and by mail send notice to all Certificateholders,
asking them to vote whether they wish to remove the Special Servicer. Upon (i) the written direction of Holders of each Class
of Non-Reduced Certificates evidencing greater than 50% of the aggregate Voting Rights of each Class of Non-Reduced Certificates
within 180 days of the initial request for a vote 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 (A) subject
to Section 6.08(i) of this Agreement, terminate all of the rights and obligations of the Special Servicer under this Agreement
and appoint the recommended successor Special Servicer and (B) promptly notify the 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 the Certificate Administrator does not receive
the required written direction contemplated by clause (i) of the second preceding sentence within 180 days of
the initial request for such vote, 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 

 

    	-285-

    	 

    

 

Servicer under this Agreement 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).

 

(c)           
In no event may a successor Special Servicer be a current or former Operating Advisor or any Affiliate of such current or
former Operating Advisor. 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 Whole Loan, 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

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, that 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, Certificateholders
or 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 and (ii) subject to Section
11.13 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)           
[Reserved.]

[Reserved.]

 

    	-286-

    	 

    

 

(i)             
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 Mortgage
Loans and the Serviced Whole Loans 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).

 

(j)            
If (1) a replacement special servicer is appointed with respect to a Serviced Whole Loan or any related REO Property in
accordance with Article VII or (2) an Excluded Special Servicer is appointed with respect to an Excluded Special Servicer
Loan, such that there are multiple parties acting as Special Servicer hereunder, then, unless the context clearly requires otherwise:
(i) when used in the context of imposing duties and obligations on the Special Servicer hereunder or the performance of such duties
and obligations, the term “Special Servicer” shall mean (A) the applicable Serviced Whole Loan Special Servicer, insofar
as such duties and obligations relate to the subject Serviced Whole Loan or any related REO Property, (B) the applicable Excluded
Special Servicer, insofar as such duties and obligations relate to the subject Excluded Special Servicer Loan or any related REO
Property, and (C) shall mean the General Special Servicer (as defined below in subsection (i)), in all other cases (provided
that in Section 3.15 and Article VII of this Agreement, the term “Special Servicer” shall mean each of
the Serviced Whole Loan Special Servicer, the Excluded 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 and/or other items, the term
“Special Servicer” shall mean (A) the applicable Serviced Whole Loan Special Servicer, insofar as such information,
funds, documents, instruments and/or other items relate to the subject Serviced Whole Loan or any related REO Property, (B) the
applicable Excluded Special Servicer, insofar as such information, funds, documents, instruments and/or other items relate to the
subject Excluded Special Servicer Loan or any related REO Property and (C) shall mean the General 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, the term “Special Servicer”
shall mean the General Special Servicer only; (iv) when used in the context of the Special Servicer being replaced pursuant
to this Section 6.08 by the Controlling Class Representative or the applicable Certificateholders the term “Special
Servicer” shall mean the General Special Servicer, the applicable Serviced Whole Loan Special Servicer or the Excluded Special
Servicer, if applicable; (v) when used in the context of granting the Special Servicer any protections, limitations on liability,
immunities and/or indemnities hereunder, the term “Special Servicer” shall mean each of the Serviced Whole Loan Special
Servicer, the Excluded Special Servicers (if any) and the General Special Servicer; and (vi) when used in the context of requiring
indemnification from, imposing liability on, or exercising any remedies against, the Special Servicer for any breach of a representation,
warranty or covenant hereunder or for any negligence, bad faith or willful misconduct in the performance of duties and obligations
hereunder or any negligent disregard of such duties and obligations or otherwise holding the Special Servicer responsible for any
of the

 

    	-287-

    	 

    

 

foregoing, the term “Special Servicer” shall mean the applicable Serviced Whole Loan Special Servicer, the applicable
Excluded Special Servicer or the General Special Servicer, as applicable.

 

(k)             References
in this Agreement to “General Special Servicer” mean the Person performing the duties and obligations of special servicer
with respect to the Mortgage Loans(exclusive of (A) any Serviced Whole Loan or related REO Property as to which a different Serviced
Whole Loan Special Servicer has been appointed with respect thereto and (B) any Excluded Special Servicer Loan or any related
REO Property as to which a different Excluded Special Servicer has been appointed with respect thereto).

 

(l)             Notwithstanding anything to the contrary contained in this Section 6.08, if the Special Servicer has obtained knowledge
that it has become a Borrower Party with respect to any Mortgage Loan or Serviced Whole Loan, then the Special Servicer shall resign
in such capacity with respect to such Excluded Special Servicer Loan. Prior to the occurrence and continuance of a Control Termination
Event, if the Excluded Special Servicer Loan is not also an Excluded Loan, the Controlling Class Representative shall appoint (and
replace with or without cause) the Excluded Special Servicer, as successor to the resigning Special Servicer, for the related Excluded
Special Servicer Loan in accordance with this Agreement. At any time after the occurrence and during the continuance of a Control
Termination Event or if an Excluded Special Servicer Loan is also an Excluded Loan, the resigning Special Servicer shall use reasonable
efforts to appoint the Excluded Special Servicer and shall, at the expense of the Issuing Entity,
petition any court of competent jurisdiction for the appointment of a successor Excluded Special Servicer if one is not appointed
within sixty (60) days of the Special Servicer’s notice of resignation. 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 Loan. It shall be a condition to any such
appointment that (i) the Rating Agencies confirm that the appointment would not result in a qualification, downgrade or withdrawal
of any of their then current ratings of the Certificates and the equivalent from each NRSRO hired to provide ratings with respect
to any commercial mortgage-backed securities backed by a Serviced Companion Loan, (ii) the Excluded Special Servicer is a replacement
special servicer meeting the applicable requirements of this Agreement and (iii) the Excluded Special Servicer delivers to the
Depositor and any applicable depositor related to another securitization that includes a Serviced Companion Loan, the information,
if any, required pursuant to Item 6.02 of the Form 8-K Current Report 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 Serviced Whole Loan prior to such Mortgage Loan or Serviced Whole
Loan, as the case may be, becoming an Excluded Special Servicer 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 Loan) with
respect to such Mortgage Loan or Serviced Whole Loan, as the case may be, (1) the related Excluded Special Servicer shall resign,
(2) such Mortgage Loan or Serviced Whole Loan, as the case may be, shall no longer be an Excluded Special Servicer Loan, (3) such
original Special Servicer shall become the Special Servicer again for such Mortgage Loan or Serviced Whole Loan, as the case may
be, and (4) such original Special Servicer shall be entitled to all Special Servicing Compensation with respect to such Mortgage
Loan or Serviced Whole Loan, as the case may be, earned during such

 

    	-288-

    	 

    

 

time on and after it resumes its duties as Special Servicer
with respect to such Mortgage Loan or Serviced Whole Loan, as the case may be.

 

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

 

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

 

Section 6.09      The Controlling Class Representative.

 

(a)           
For so long as no Control Termination Event has occurred and is continuing and exclusive of any Excluded Loan, the Controlling
Class Representative shall be entitled to (1) advise the Special Servicer with respect to all Specially Serviced Loans, (2) advise
the Special Servicer with respect to non-Specially Serviced Loans as to all matters for which the Master Servicer must obtain the
consent or deemed consent of the Special Servicer for a Major Decision, and (3) with respect to any Non-Serviced Mortgage Loan,
exercise consultation and consent rights (if any) and attend annual meetings with an Other Master Servicer and an Other Special
Servicer, in each case, to the extent the holder of a Non-Serviced Mortgage Loan is entitled to such rights pursuant to the related
Co-Lender Agreement. In addition, notwithstanding anything herein to the contrary, except as set forth in, and in any event subject
to Section 6.09(b) and the second and third paragraphs of this Section 6.09(a), both (a) the Master Servicer
shall not be permitted to take any of the actions constituting a Major Decision unless it has obtained the consent of the Special
Servicer, 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 Master Servicer’s written analysis and recommendation and all information
in the Master Servicer’s possession or reasonably available to it that the Special Servicer may reasonably request) 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 (b) for so long as no Control Termination
Event has occurred and is continuing, the Special Servicer shall not be permitted to consent to the Master Servicer’s taking
any of the actions constituting a Major Decision, nor will the Special Servicer itself be permitted to take any of the actions
constituting a Major Decision as to which the Controlling Class Representative has objected in writing within ten (10) Business
Days (or in the case of a determination of an Acceptable Insurance Default, twenty (20) days) after receipt of the written recommendation
and analysis from the Special Servicer; provided that (i) if such written objection has not been

 

    	-289-

    	 

    

 

received by the Special
Servicer within such ten (10) Business Day period or twenty (20) day period, as applicable, then the Controlling Class Representative
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 Loan; provided, further, that, 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 the Controlling Class Representative prior to the occurrence and continuance of a Control Termination Event in this Agreement,
is necessary to protect the interests of the Certificateholders and, with respect to any Serviced Whole Loan (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), the Special Servicer or Master Servicer, as applicable, may take
any such action without waiting for the Controlling Class Representative’s (or, if applicable, the Special Servicer’s
(but only with respect to a non-Specially Serviced Loan)) response. The Special Servicer is not required to obtain the consent
of the Controlling Class Representative for any Major Decision following the occurrence and during the continuance of a Control
Termination Event; provided that, after the occurrence and during the continuance of a Control Termination Event, the Special
Servicer shall consult with the Controlling Class Representative (other than with respect to any Excluded Loan and until the occurrence
and continuance of a Consultation Termination Event) and the Operating Advisor in connection with any Major Decision and consider
alternative actions recommended by the Controlling Class Representative and the Operating Advisor, but 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; provided that such consultation is not binding on the Special Servicer. Notwithstanding
the foregoing, the Controlling Class Representative shall have no consent or consultation rights with respect to Major Decisions
with respect to any Excluded Loan.

 

In addition, for so long
as no Control Termination Event has occurred and is continuing, the Controlling Class Representative (other than with respect to
any Excluded Loan) may direct the Special Servicer to take, or to refrain from taking, such other actions with respect to a Mortgage
Loan or Serviced Whole Loan, as applicable, as the Controlling Class Representative may deem advisable or as to which provision
is otherwise made herein. Notwithstanding anything herein to the contrary, no such direction, and no objection contemplated by
the preceding paragraph or this paragraph, may require or cause the Master Servicer or the Special Servicer to violate any provision
of any Mortgage Loan Documents, applicable law, any related Co-Lender Agreement or any intercreditor agreement, 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 the Master Servicer, the Special Servicer, the Certificate Administrator,
the Trust or the Trustee to liability, or materially expand the scope of the Master Servicer’s or the Special Servicer’s
responsibilities hereunder or cause the Master Servicer or the Special Servicer to act, or fail to act, in a manner which in the
reasonable judgment of the Master Servicer or the Special Servicer is not in the best interests of the Certificateholders and/or
the Serviced Companion Loan Holders.

 

    	-290-

    	 

    

 

In the event the Special
Servicer or Master Servicer, as applicable, determines that a refusal to consent by the Controlling Class Representative or any
advice from the Controlling Class Representative would otherwise cause the Special Servicer or Master Servicer, as applicable,
to violate the terms of any Mortgage Loan Documents, the 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 the Controlling Class Representative, the Trustee and, for posting
to the Rule 17g-5 Information Provider’s Website pursuant to Section 11.13 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, of any action by the Master Servicer or the Special Servicer in accordance with the direction of or approval
of the Controlling Class Representative that does not violate any law or the Servicing Standard or any other provisions of this
Agreement, any related Co-Lender Agreement or any intercreditor agreement will not result in any liability on the part of the Master
Servicer or the Special Servicer.

 

The Controlling Class
Representative will have no liability to the Trust Fund or the 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 that: (i) the Controlling Class Representative may have special relationships
and interests that conflict with those of Holders of one or more Classes of Certificates; (ii) the Controlling Class Representative
may act solely in the interests of the Holders of the Controlling Class; (iii) the Controlling Class Representative does not have
any liability or duties to the Holders of any Class of Certificates other than the Controlling Class; (iv) the Controlling Class
Representative may take actions that favor interests of the Holders of the Controlling Class over the interests of the Holders
of one or more other Classes of Certificates; and (v) the Controlling Class Representative shall have no liability whatsoever (other
than to a Controlling Class Certificateholder) for having so acted as set forth in clauses (i)-(iv) of this paragraph,
and no Certificateholder may take any action whatsoever against the Controlling Class Representative or any affiliate, director,
member, officer, employee, shareholder, member, partner, agent or principal thereof for having so acted; provided, however,
that, in the case of a Serviced Whole Loan, the rights of the Controlling Class Representative are subject to the related Co-Lender
Agreement.

 

Any Non-Serviced Whole
Loan Controlling Holder, with respect to a Non-Serviced Whole Loan, shall have no liability to the Trust Fund or the Certificateholders
for any action taken, or for refraining from the taking of any action, or for errors in judgment. By its acceptance of a Certificate,
each Certificateholder acknowledges and agrees that any such Non-Serviced Whole Loan Controlling Holder, with respect to the related
Non-Serviced Whole Loan, may take actions that favor the interests of one or more classes of the certificates issued under the
related Other Pooling and Servicing Agreement including the holders of the controlling class

 

    	-291-

    	 

    

 

under such Other Pooling and Servicing
Agreement over other Classes of the Certificates, and that such Non-Serviced Whole Loan Controlling Holder, with respect to such
Non-Serviced Whole Loan, may have special relationships and interests that conflict with those of Holders of some Classes of the
Certificates, that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, may act solely
in the interests of the holders of the controlling class under the related Other Pooling and Servicing Agreement, that such Non-Serviced
Whole Loan Controlling Holder, shall not be liable to any Certificateholder, by reason of its having acted solely in the interests
of the holders of the controlling class under the related Other Pooling and Servicing Agreement, and that the Non-Serviced Whole
Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, shall have no liability whatsoever for having so acted,
and no Certificateholder may take any action whatsoever against such Non-Serviced Whole Loan Controlling Holder, with respect to
such Non-Serviced Whole Loan, or any director, officer, employee, agent or principal thereof for having so acted.

 

(b)           
Notwithstanding anything to the contrary contained herein: (i) after the occurrence and during the continuance of a
Control Termination Event, 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 (other than with respect to any
Excluded Loan), and the Master Servicer, the 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 to the extent such party would have been
required to obtain the consent of the Controlling Class Representative but for the occurrence of a Control Termination Event as
set forth herein (other than with respect to any Excluded Loan); (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 Controlling Class Representative; and (iv) none of the rights of the Controlling
Class Representative will apply with respect to an Excluded 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 or based upon advice from a Companion Loan Holder that would cause any one of them
to violate applicable law, the terms of the related Serviced Whole Loan, the related Co-Lender Agreement, this Agreement, including
the Servicing Standard, or the REMIC Provisions or that would (i) expose the Master Servicer, the Special Servicer, the Depositor,
a Mortgage Loan Seller, the Trust Fund, the Trustee, the Operating Advisor, the Certificate Administrator 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 Servicer’s responsibilities, or (iii) 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 or the Servicing Standard.

 

(d)           
Each Certificateholder and Beneficial 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

 

    	-292-

    	 

    

 

Certificate Administrator and to notify the Certificate Administrator 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 thereof. Any such Certificateholder (or Beneficial 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 when such Certificateholder (or Beneficial Owner) or
designee is appointed Controlling Class Representative and when it is removed or resigns. Upon receipt of such notice, the
Certificate Administrator shall notify the Special Servicer, the Master Servicer, the Operating Advisor and the Trustee of the
identity of the Controlling Class Representative, any resignation or removal thereof and/or any new Holder or Beneficial Owner
of a Control Eligible Certificate. In addition, upon the request (which may be by email) of the Master Servicer, the Special Servicer,
the Operating Advisor or the Trustee, as applicable, the Certificate Administrator shall provide (on a reasonably prompt basis)
the identity of each Companion Loan Holder, the then-current Controlling Class and a list of the Certificateholders (or Beneficial
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 3.28(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) to such requesting party, and each of the Master Servicer, Special Servicer, Operating Advisor and the Trustee
shall be entitled to rely on such information so provided by the Certificate Administrator and shall be entitled to assume that
the identity of the Controlling Class Representative has not changed absent notice of a replacement of the Controlling Class Representative
by a majority of the Controlling Class, or the resignation of the then-current Controlling Class Representative.

 

In the event of a change
in the Controlling Class, the Certificate Administrator shall promptly contact Eightfold Real Estate Capital, L.P., or, if applicable,
any successor Controlling Class Representative or Controlling Class Certificateholder(s), and determine whether such entity
is the Holder (or Beneficial Owner) of at least a majority of the Controlling Class (in effect after such change in Controlling
Class) by Certificate Principal Balance. If at any time that Eightfold Real Estate Capital, L.P. or any successor Controlling Class
Representative or Controlling Class Certificateholder(s) is no longer the Holder (or Beneficial Owner) of at least a majority of
the Controlling Class by Certificate Principal 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 Principal
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 both be deemed to have occurred and shall be deemed to continue until
such time as the Certificate Administrator receives either such notice. The Certificate Administrator shall promptly notify the
Master Servicer and the Special Servicer of the occurrence of a deemed Control Termination Event and/or a deemed Consultation Termination
Event in accordance with the immediately preceding sentence.

 

    	-293-

    	 

    

 

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.

 

(e)           
Once a Controlling Class Representative has been selected pursuant to clause (c) above, each of the Master
Servicer, the Special Servicer, the Operating Advisor, the Depositor, the Certificate Administrator, the Trustee and each other
Certificateholder (or Beneficial Owner, if applicable) shall be entitled to rely on such selection unless a majority of the
Certificateholders of the Controlling Class, by Certificate Principal 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 Beneficial Owner or Beneficial Owners (through the Depository, unless the Certificate Administrator shall have been previously
provided with the name and address of such Beneficial Owner or Beneficial Owners) of such event and shall request that it be informed
of any change in the identity of the related Beneficial 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 F Certificates is the Controlling
Class, the Holder of more than 50% of the Controlling Class Certificates (by Certificate Principal 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, 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”).
Any such waiver shall remain effective, and a Control Termination Event and a Consultation Termination Event shall be deemed to
exist, with respect to such Holder and such Class until such time as the Opting-Out Party has (i) sold a majority of the Class F
Certificates (by outstanding Certificate Principal 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 F Certificates that it does not own, (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 F Certificates (such sale and certification, a “Class F Transfer”). Following
any such Class F Transfer, the successor holder of more than 50% of the Class F Certificates (by outstanding Certificate
Principal Balance), if the Class F

 

    	-294-

    	 

    

 

Certificates are the Controlling Class Certificates, shall again have the rights of the
Controlling Class Representative as set forth herein (including the rights to appoint a Controlling Class Representative or cause
the exercise of the rights of the Controlling Class Representative) 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 and 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 such successor
Certificateholder described above in this paragraph shall have any consent rights with respect to any Mortgage Loan that became
a Specially Serviced Loan prior to the Class F Transfer and had not also become a Corrected Mortgage Loan prior to such Class F
Transfer until such time as such Mortgage Loan becomes a Corrected Mortgage Loan.

or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer
or the Special Servicer, as applicable, and such decree or order shall have remained in force undischarged, undismissed or unstayed
for a period of 60 days; or

 

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

all of its property; or

 

(vii)          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

 

    	-296-

    	 

    

 

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
Moody’s or KBRA has (i) qualified, downgraded or withdrawn its rating or ratings of one or more Classes of Certificates,
or (ii) placed one or more Classes of Certificates on “watch status” in contemplation of rating downgrade or withdrawal
and, in the case of either of clauses (i) or (ii), publicly citing servicing concerns with the Master Servicer or any Special
Servicer, as applicable, as the sole or material factor in such rating action (and such qualification, downgrade, withdrawal or
“watch status” placement has not been withdrawn by such Rating Agency, within 60 days of such event); or

 

(ix)            a
servicing officer of the Master Servicer obtains knowledge that the Master Servicer has ceased to have a commercial master servicer
rating of at least “CMS3” from Fitch and that rating is not reinstated within 60 days or, with respect to any
Special Servicer, a servicing officer of the Special Servicer obtains knowledge that the Special Servicer has ceased to have a
commercial special servicer rating of at least “CSS3” from Fitch and that rating is not reinstated within 60 days,
as the case may be; or

 

(x)           
a servicing officer of the Master Servicer or the Special Servicer, as applicable, obtains knowledge that the Master Servicer
or the Special Servicer, as applicable, has failed to maintain a ranking by Morningstar equal to or higher than “MOR CS3”
as a master servicer or special servicer, as applicable, and the Master Servicer or the Special Servicer, as applicable, is not
reinstated to that ranking within 60 days (provided that if Morningstar has not issued a ranking with respect to such Master
Servicer or Special Servicer, as applicable, then the following shall constitute a Servicer Termination Event: Morningstar has
(i) qualified, downgraded or withdrawn its ratings of one or more Classes of Certificates, or (ii) placed one or more Classes of
Certificates on “watch status” in contemplation of rating downgrade or withdrawal and, in the case of either clauses
(i) or (ii), publicly citing servicing concerns with the Master Servicer or the Special Servicer, as applicable, as
the sole or material factor in such rating action (and such qualification, downgrade, withdrawal or “watch status”
placement has not been withdrawn by Morningstar within 60 days of such event)); or

 

(xi)            the
Master Servicer or the Special Servicer, as applicable, or any primary servicer or Sub-Servicer appointed by the Master Servicer
or the Special Servicer after the Closing Date (but excluding any Sub-Servicer set forth on Exhibit S), shall fail
to deliver during any period in which the Trust or the Other Securitization Trust is subject to the reporting requirements of
the Exchange Act the items required to be delivered by this Agreement by the time required under Article X after any applicable
grace periods (any primary servicer or Sub-Servicer that defaults in accordance with this Section 7.01(a)(xi) shall be
terminated at the direction of the Depositor);

 

then, and in each and every such case,
so long as a Servicer Termination Event is continuing and shall not have been remedied, either (i) the Trustee may or (ii) upon
the written direction of the Holders of Certificates evidencing at least 25% of the aggregate Voting Rights of all Certificates
(or, solely in the case of the related Serviced Whole Loan, at the direction of an affected

 

    	-297-

    	 

    

 

Serviced Companion Loan Holder) to
the Trustee, 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), (ix), (x) or (xi) 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 Whole Loan.

 

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), Section 7.01(a)(ix) or Section 7.01(a)(x) 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 Whole Loans under this Agreement from at least three (3) Persons qualified to act as a
successor Master Servicer hereunder in accordance with Section 6.02 (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 offer proposal shall require any Successful Bidder (as defined below),
as a condition of such offer, 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 offer (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 offer 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)

 

    	-298-

    	 

    

 

of
this Agreement, the amount of such cash offer received from the Successful Bidder (net of “out-of-pocket” expenses
incurred in connection with obtaining such offer 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 Whole Loans, 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 offer 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 Whole Loans 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 Whole Loans or otherwise, shall pass to and be vested in the Trustee
pursuant to and under this 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 Whole Loans 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

 

    	-299-

    	 

    

 

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 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 Serviced Whole Loan Custodial Account, any REO Account or Lockbox Account shall thereafter be received with respect
to the Mortgage Loans and Serviced Whole Loans, 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
Section 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 affects only a Serviced Companion Loan, the related Serviced Companion Loan
Holder or the rating on a Class of Serviced Companion Loan Securities, then the Master Servicer may not be terminated in accordance
with Section 7.01(c), but, upon the written direction of the Serviced Companion Loan Holder, the Master Servicer will be
required to appoint, within 30 days of such direction, a sub-servicer (or, if any Serviced Whole Loan is currently being sub-serviced,
to replace, within 30 days of the Trustee’s request, 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 Companion Loan Holder in accordance with
this Section 7.01(d), the Master Servicer shall obtain at its own expense a Companion Loan Rating Agency Confirmation from
each Companion Loan Rating Agency, which shall be delivered and addressed to the related Companion Loan Holder and to the Trustee.
The related sub-servicing agreement shall provide that any sub-servicer appointed by the Master Servicer at the direction of a
Companion Loan Holder in accordance with this Section 7.01(d) shall be responsible for all duties, and shall be entitled
to all compensation (other than the Excess Servicing Fee Right), of the Master Servicer under this Agreement with respect to the
related Serviced Whole Loan, except that the Master

 

    	-300-

    	 

    

 

Servicer
shall be entitled to retain a portion of the Servicing Fee for the Mortgage Loan that is part of the related Serviced Whole Loan
calculated at 0.0% per annum 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 Whole Loan in the event
that any Serviced Whole Loan 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 Whole Loan 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 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 or the Master Servicer has received notice from Moody’s, Fitch, KBRA
or Morningstar that the Master Servicer no longer is an approved master servicer then such party shall promptly notify the others
and the Special Servicer, and the Certificate Administrator shall notify the related Companion Loan Holder 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; 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 liabilities, representations and 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

 

    	-301-

    	 

    

 

Section
3.07 of this Agreement nor shall the Trustee be required to purchase any Mortgage Loan or Serviced Whole Loan hereunder. As
compensation therefor, the Trustee (or any other successor Master Servicer or Special Servicer assuming the obligations of the
Master Servicer or the Special Servicer, as applicable) 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 any related
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, 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, an 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 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, for so long as no Control Termination
Event has occurred or is continuing the Controlling Class Representative shall have the right to approve any such successor Special
Servicer. No appointment of a successor to the Master Servicer or Special Servicer hereunder shall be effective until the assumption
by such successor of all the Master Servicer’s or Special Servicer’s responsibilities, duties and liabilities hereunder.
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 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 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; 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 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

 

    	-302-

    	 

    

 

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 Companion Loan Holders and electronically, for posting to the Rule 17g-5 Information
Provider’s Website pursuant to Section 11.13 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, any affected Companion Loan Holder (to the extent the Certificate Administrator has received the notice information
for such Companion Loan Holder after a request therefor) and electronically, for posting to the Rule 17g-5 Information Provider’s
Website pursuant to Section 11.13 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.

 

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 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 Serviced Whole Loan 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.

 

    	-303-

    	 

    

 

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 a Serviced Whole Loan 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 Serviced Whole Loan Custodial
Account or the Lower-Tier 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 with the consent of all of the Certificateholders
of the affected Classes, and (b) a Servicer Termination Event under Section 7.01(a)(xi) 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)) 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 Companion Loan Holder related
to a Serviced Whole Loan (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 Companion Loan Holder will be entitled to request that the
Master Servicer appoint, within 60 days of the applicable Companion Loan Holder’s request, a sub-servicer (or, if the applicable
Serviced Whole Loan is currently being subserviced, to replace, within 60 days of the applicable Companion Loan Holder’s
request, the then-current sub-servicer with a new sub-servicer) with respect to the applicable Serviced Whole Loan. In connection
with the Master Servicer’s appointment of a sub-servicer at the request of a 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
Companion Loan Holder. The related sub-servicing agreement shall provide that any sub-servicer appointed by the Master Servicer
at the request of a Companion Loan Holder in accordance with this Section 7.05 shall be responsible for all duties, and
shall be entitled to all compensation (other than the Excess Servicing Fee Right), of the Master Servicer under this Agreement
with respect to the applicable Serviced Whole Loan, except that the Master Servicer shall be entitled to retain a

 

    	-304-

    	 

    

 

portion
of the master servicing fee for the related Mortgage Loan calculated at 0.0% per annum. 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 Whole Loan in the event that any Serviced
Whole Loan 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 Whole Loan 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 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, which shall be delivered and addressed to
the related Companion Loan Holder and to the Trustee, 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 thirty (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 in accordance with the Operating Advisor Standard which failure shall continue
unremedied for a period of thirty (30) days;

 

    	-305-

    	 

    

 

(iii)         
any failure by the Operating Advisor to be an Eligible Operating Advisor, 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 Operating Advisor, and such decree or order shall
have remained in force undischarged or unstayed for a period of sixty (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.

 

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 electronically by posting such notice on its internet website and by mail, 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 any rights or obligations that accrued prior to such termination, including
accrued and unpaid compensation, and 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 thereof 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 written direction of holders of

 

    	-306-

    	 

    

 

Certificates
evidencing more than 50% of the Voting Rights of the Non-Reduced Certificates that exercise their right to vote (provided
that Holders of at least 50% of the Voting Rights of the Non-Reduced Certificates exercise their right to vote), the Trustee shall
terminate all of the rights and obligations of the Operating Advisor under this Agreement (other than any rights or obligations
that accrued prior to such termination, including accrued and unpaid compensation, and indemnification rights arising out of events
that occurred prior to such termination) by written notice to the Operating Advisor, and the proposed successor operating advisor
shall be appointed. 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 Beneficial Owner may access such notices on the
Certificate Administrator’s Website and each Certificateholder and Beneficial 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 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 any resignation under the circumstances
contemplated in Section 6.04(b) 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, which successor Operating Advisor may be an Affiliate of the Trustee and shall be the proposed Operating
Advisor in the case of a termination pursuant to Section 7.06(b) of this Agreement; provided, however, that
if the Trustee is the successor Master Servicer or successor Special Servicer, neither the Trustee nor any of its Affiliates shall
be the successor 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 Controlling Class Representative
and each Certificateholder within one Business Day of such appointment. 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

 

    	-307-

    	 

    

 

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. In the event the Operating
Advisor is either (i) required to resign due to the Depositor, the Master Servicer, the Special Servicer, the Controlling
Class Representative, a Sponsor or an Affiliate thereof becoming the Operating Advisor or (ii) terminated pursuant to this
Section 7.06, then, 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 Rating Agencies, the Special Servicer, the
Master Servicer, the Certificate Administrator (who shall, as soon as possible, give written notice thereof to the Certificateholders),
the Depositor and, prior to the occurrence and continuance of a Consultation Termination Event, the Controlling Class Representative
and, for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section 11.13 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 such resignation or
termination, including accrued and unpaid compensation, and indemnification rights arising out of events occurring prior to such
resignation or termination).

 

(e)           
Notwithstanding the foregoing, the Operating Advisor may resign from its obligations and duties under this Agreement, without
payment of any penalty, at any time (a) the aggregate Certificate Principal Balances of the Class A-1, Class A-2, Class A-3, Class
A-4, Class A-SB, Class A-S, Class B, Class C, Class D and Class E Certificates have been reduced to zero, or (b) the aggregate
Stated Principal Balance of the Mortgage Loans in the Trust is equal to or less than 1% of the aggregate Cut-off Date Principal
Balance of the Mortgage Loans; provided that no successor operating advisor shall be required to be appointed in connection with,
or as a condition to, such resignation.

Section 8.01    
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

 

    	-308-

    	 

    

 

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, 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 Securities 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
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

 

    	-309-

    	 

    

 

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) 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 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 to its respective duties as Trustee or Certificate Administrator, as applicable,
in related 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
contained in Section 2.07 or Section 2.08 herein; provided, however, that the Trustee or the Certificate
Administrator 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; and

 

(vi)           Neither
the Trustee nor the Certificate Administrator shall be charged with knowledge of any act, failure to act or breach of any
Person upon the occurrence of which the Trustee or the Certificate Administrator, as applicable, may be required to act,
unless a Responsible Officer of the Trustee or the Certificate Administrator, as applicable, obtains actual knowledge of such
failure. Each of the Trustee and the Certificate Administrator shall be deemed to have actual knowledge of the Master

 

    	-310-

    	 

    

 

Servicer’s or the Special Servicer’s failure to provide scheduled reports, certificates and statements when and
as required to be delivered to the Trustee or the Certificate Administrator, as applicable, pursuant to this Agreement.

 

None of the provisions
contained in this Agreement shall require the Trustee or the Certificate Administrator, in its capacity as Trustee or the Certificate
Administrator, as applicable, to expend or risk its own funds, or otherwise incur financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if in the opinion of the Trustee or the Certificate
Administrator, as applicable, the repayment of such funds or adequate indemnity against such risk or liability is not reasonably
assured to it, and none of the provisions contained in this Agreement shall in any event require the Trustee or the Certificate
Administrator, as applicable, to perform, or, with respect to the Trustee, be responsible for the manner of performance of, any
of the obligations of the Master Servicer, the Special Servicer or the Operating Advisor under this Agreement, except, with respect
to the Trustee, during such time, if any, as the Trustee shall be the successor to, and be vested with the rights, duties, powers
and privileges of, the Master Servicer or the Special Servicer in accordance with the terms of this Agreement. Neither the Trustee
nor the Certificate Administrator shall be required to post any surety or bond of any kind in connection with its performance of
its obligations under this Agreement and neither the Trustee nor the Certificate Administrator shall be liable for any loss on
any investment of funds pursuant to this Agreement (other than any funds invested with it in its commercial capacity or at its
discretion).

Operating Advisor, the Master Servicer, the Special Servicer or the Trustee may at any time request from the Certificate Administrator
written confirmation of whether a Consultation Termination Event or a Control Termination Event occurred during the previous calendar
year and the Certificate Administrator shall deliver such confirmation, based on information in its possession, to the requesting
party within 15 days of such request. Further, based on information in its possession, the Certificate Administrator shall notify
the Operating Advisor, the Master Servicer and the Special Servicer, without any request for such notice from the Operating Advisor,
the Master Servicer or the Special Servicer, within 10 days of the commencement or cessation of any Consultation Termination Event

Neither the Trustee nor the Certificate Administrator shall be bound to make any investigation of matters arising under
this Agreement or into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond or other paper or document, unless requested in writing to do so by Holders of Certificates
entitled to at least 25% (or such other percentage 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 costs, expense, or liability as a condition to taking any

 

    	-312-

    	 

    

 

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; provided
that the Trustee or the Certificate Administrator, as the case may be, may not perform any duties hereunder through any Person
that is a Prohibited Party; and

 

(vii)          For
purposes of this Agreement, the Trustee or the Certificate Administrator, as applicable, shall have notice of an event only when
a Responsible Officer of the Trustee or the Certificate Administrator, as applicable, has received written notice or obtains actual
knowledge of such event.

 

(b)            Following
the Startup Day, neither the Trustee nor the Certificate Administrator shall, except as expressly required by any provision of
this Agreement, accept any 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,
at any time that any Certificates are outstanding or subject either 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.

 

Neither the Trustee nor
the Certificate Administrator shall have any duty to conduct any affirmative investigation as to the occurrence of any condition
requiring the repurchase of any Mortgage Loan by the Depositor pursuant to this Agreement or the eligibility of any Mortgage Loan
for purposes of this Agreement.

 

Other than in the case
of actual fraud (as determined by a non-appealable final court order), neither the Trustee nor the Certificate Administrator shall
be liable for special, punitive, indirect or consequential loss or damage of any kind whatsoever (including but not limited to
lost profits), even if the Trustee or the Certificate Administrator has been advised of the likelihood of such loss or damage and
regardless of the form of action.

(d)            Neither the Trustee nor the Certificate Administrator shall be responsible for delays or failures in performance resulting
from acts beyond its control (such acts include but are not limited to acts of God, strikes, lockouts, riots and acts of war).

 

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

 

(f)            Each
of the Certificate Administrator, Custodian, Rule 17g-5 Information Provider, Authenticating Agent, Paying Agent and Certificate
Registrar shall be entitled to the same rights, indemnities, immunities, privileges and protections afforded to the Trustee hereunder
in the same manner as if such party were the named Trustee herein.

the Master Servicer, the Special Servicer and the Operating Advisor make no representations or warranties as to the validity or
sufficiency of this Agreement, of the Certificates or any prospectus used to offer the Certificates for sale or the validity,
enforceability or sufficiency of any Mortgage Loan or related document. Neither the Trustee nor the Certificate Administrator
shall at any time have any responsibility or liability for or with respect to the legality, validity and enforceability of any
Mortgage, any Mortgage Loan, or the perfection and priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with respect to the sufficiency of the Trust Fund or its ability to generate the payments to be distributed to Certificateholders
under this Agreement. Without limiting the foregoing, neither the Trustee nor the Certificate Administrator shall be liable or
responsible for: the existence, condition and ownership of any Mortgaged Property; the existence of any hazard or other insurance
thereon (other than if the Trustee shall assume the duties of the Master Servicer or the Special Servicer pursuant to Section
7.02 of this Agreement, in the Trustee’s capacity as Master Servicer or Special Servicer) or the enforceability
thereof; the existence of any Mortgage Loan or the contents of the related Mortgage File on any computer or other record thereof
(other than if the Trustee shall assume the duties of the Master Servicer or the Special Servicer pursuant to Section 7.02
of this Agreement, in the Trustee’s capacity as Master Servicer or Special Servicer); the validity of the assignment
of any Mortgage Loan to the Trust Fund or of any intervening assignment; the completeness of any Mortgage File (except for its

the Operating Advisor with any warranty or representation made under this Agreement or in any related document or the accuracy
of any such warranty or representation prior to the Trustee’s receipt of notice or other discovery of any non-compliance
therewith or any breach thereof; any investment of moneys by or at the direction of the Master Servicer or any loss resulting
therefrom (other than if the Trustee shall assume the duties of the Master Servicer or the Special Servicer pursuant to Section
7.02 of this Agreement, in the Trustee’s capacity as Master Servicer or Special Servicer), it being understood that
the Trustee shall remain responsible for any Trust Fund property that it may hold in its individual capacity; the acts or omissions
of any of the Depositor, the Master Servicer, the Special Servicer or the Operating Advisor (other than if the Trustee shall assume
the duties of the Master Servicer or the Special Servicer pursuant to Section 7.02 of this Agreement, in the Trustee’s
capacity as Master Servicer or Special Servicer) or any Sub-Servicer or any Mortgagor; any action of the Master Servicer,
the Special Servicer or the Operating Advisor (other than if the Trustee shall assume the duties of the Master Servicer or the
Special Servicer pursuant to Section 7.02 of this Agreement, in the Trustee’s capacity as Master Servicer or Special
Servicer) or any Sub-Servicer taken in the name of the Trustee except to the extent such action is taken at the express written
direction of the Trustee; the failure of the Master Servicer or the Special Servicer or any Sub-Servicer to act or perform any
duties required of it on behalf of the Trust Fund or the Trustee as applicable hereunder; or any action by or omission of the
Trustee taken at the instruction of the Master Servicer or the Special Servicer (other than if the Trustee shall assume the duties
of the Master Servicer or the Special Servicer pursuant to Section 7.02 of this Agreement, in the Trustee’s capacity
as Master Servicer or Special Servicer) unless the taking of such action is not permitted by the express terms of this Agreement;
provided, however, that the foregoing shall not relieve the Trustee or the Certificate Administrator, as applicable,
of its obligation to perform its duties as specifically 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 or application of any funds paid to the Depositor, the Master Servicer or the Special Servicer
in respect of the assignment of the Mortgage Loans or deposited in or withdrawn from the Collection Account, the Lower-Tier Distribution
Account, the Upper-Tier Distribution Account, the Lockbox Account, the Escrow Accounts, the Interest Reserve Account, the Excess
Liquidation Proceeds Reserve Account or any other account maintained by or on behalf of the Master Servicer or the Special Servicer,
other than any funds held by the Trustee or the Certificate Administrator, as applicable. Neither the Trustee nor the Certificate
Administrator shall have responsibility for filing any financing or continuation statement in any public office at any time or
to otherwise perfect or maintain the perfection of any security interest or lien granted to it hereunder (unless in the case of
the Trustee, the Trustee shall have become the successor Master Servicer) or to record this Agreement. In making any calculation
hereunder which includes as a component thereof the payment or distribution of interest for a stated period at a stated rate “to
the extent permitted by applicable law,” the Trustee or the Certificate Administrator, as applicable, shall assume that
such payment is so permitted unless a Responsible Officer of the Trustee or the Certificate Administrator, as applicable, has
actual knowledge, or receives an Opinion of Counsel (at the expense of the Person asserting the impermissibility) to the effect
that such payment is not permitted by applicable law.

 

Section 8.04     Trustee
and Certificate Administrator May Own Certificates. The Trustee, the Certificate Administrator and any agent of the Trustee
or the Certificate

 

    	-315-

    	 

    

 

Administrator,
each, in its individual capacity or any other capacity, may become the owner or pledgee of Certificates, and may deal with the
Depositor and the Master Servicer in banking transactions, with the same rights it would have if it were not Trustee, the Certificate

Section 8.05     Payment
of Trustee/Certificate Administrator Fees and Expenses; Indemnification.

 

(a)            As
compensation for the performance of its duties hereunder, the Trustee shall be paid its portion of the Trustee/Certificate Administrator
Fee, which shall cover recurring and otherwise reasonably anticipated expenses of the Trustee. As compensation for the performance
of its duties hereunder, the Certificate Administrator shall be paid its portion of the Trustee/Certificate Administrator Fee,
which shall cover recurring and otherwise reasonably anticipated expenses of the Certificate Administrator. The Certificate Administrator
shall pay the Trustee the Trustee’s portion of the Trustee/Certificate Administrator Fee. The Trustee/Certificate Administrator
Fee shall be paid monthly on a Mortgage Loan-by-Mortgage Loan basis. The Trustee/Certificate Administrator Fee (which in each
case shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) shall constitute
the Trustee’s and the Certificate Administrator’s sole form of compensation for all services rendered by each of them
in the execution of the trusts hereby created and in the exercise and performance of any of the powers and duties of the Trustee
or the Certificate Administrator, as applicable, hereunder. No Trustee/Certificate Administrator Fee shall be payable with respect
to any Companion Loan. In the event that the Trustee assumes the servicing responsibilities of the Master Servicer or the Special
Servicer hereunder pursuant to or otherwise arising from the resignation or removal of the Master Servicer or the Special Servicer,
the Trustee shall be entitled to the compensation to which the Master Servicer or the Special Servicer, as the case may be, would
have been entitled.

 

(b)            Each
of the Trustee and the Certificate Administrator shall be paid or reimbursed by the Trust Fund upon its request for all reasonable
expenses, disbursements and, except for Advances otherwise reimbursable hereunder, advances incurred or made by the Trustee or
the Certificate Administrator, as applicable, pursuant to and in accordance with any of the provisions of this Agreement (including
the reasonable compensation and the expenses and disbursements of its counsel and of all persons not regularly in its employ)
to the extent such payments are “unanticipated expenses” as described in clause (d) below, except
any such expense, disbursement or advance as may arise from its negligence, bad faith or willful misconduct; provided,
however, that, subject to Section 8.01 and Section 8.02 of this Agreement, neither the Trustee nor the Certificate
Administrator shall refuse to perform any of its duties hereunder solely as a result of the failure to be paid the Trustee/Certificate
Administrator Fee or the Trustee’s expenses or the Certificate Administrator’s expenses, as applicable.

 

The Master Servicer and
the Special Servicer covenant and agree to pay or reimburse the Trustee for the reasonable out-of-pocket expenses incurred or made
by the Trustee in connection with any transfer of the servicing responsibilities of the Master Servicer or the Special Servicer,
respectively, hereunder, pursuant to or otherwise arising from the resignation or removal of the Master Servicer or the Special
Servicer, in accordance with any of the provisions of this Agreement (and including the reasonable fees and expenses and disbursements

the Trustee, the Paying Agent, the Certificate Registrar, the Custodian and the Certificate Administrator shall indemnify each

expenses) incurred by such parties (i) as a result of any willful misconduct, bad faith, fraud or negligence in the performance
of duties of the Authenticating Agent, the Paying Agent, the Certificate Registrar, the Custodian, the Certificate Administrator
or the Trustee, as the case may be, or by reason of negligent disregard of the Authenticating Agent, the Paying Agent’s,
the Certificate Registrar’s, the Custodian’s, the Certificate Administrator’s or the Trustee’s, as the
case may be, obligations or duties hereunder, or (ii) as a result of the breach by the Authenticating Agent, the Paying Agent,

expenses that the Indemnified Party may sustain in connection with this Agreement (including, without limitation, reasonable fees
and disbursements of counsel and of all persons not regularly in its employ incurred by the Indemnified Party in any action or
proceeding between the Trust Fund and the Indemnified Party or between the Indemnified Party and any third party or otherwise) arising
in respect of this Agreement or the Certificates, in each case to the extent and only to the extent, such payments are expressly
reimbursable under this Agreement, or are unanticipated expenses (as defined below), other than (i) those resulting from the
negligence, fraud, bad faith or willful misconduct, or negligent disregard of obligations and duties hereunder, of the Indemnified
Party and (ii) except to the extent such amounts are not paid pursuant to this Section 8.05, those as to which such

Agreement or the resignation or removal of the Trustee or the Certificate Administrator, as applicable, as regards rights accrued
prior to such resignation or removal and (with respect to any acts or omissions during their respective tenures) the resignation,

set to the Trustee (in connection with the removal of the Certificate Administrator), one complete set to the Certificate Administrator
(in connection with the removal of the Trustee), one complete set to the Trustee or Certificate Administrator, as applicable,
so removed and one complete set to the successor Trustee or Certificate Administrator, as applicable, so appointed and a copy
thereof shall be delivered to the Companion Loan Holders.

 

In the event that the
Trustee or the Certificate Administrator is terminated or removed pursuant to this Section 8.07, all of its rights and obligations
under this Agreement and in and to the Mortgage Loans or Serviced Whole Loans shall be terminated, other than any rights or obligations
that accrued prior to the date of such termination or removal (including the right to receive all fees, expenses and other amounts

immediately preceding paragraph, then such holders will be required to pay all the reasonable costs and expenses (including, but
not limited to, reasonable attorney’s fees and expenses) of the Trustee or Certificate Administrator, as applicable, necessary
to effect the transfer of the rights and obligations of the Trustee or Certificate Administrator, as applicable, to a successor
Trustee or Certificate Administrator.

 

Any resignation or removal
of the Trustee or the Certificate Administrator and appointment of a successor Trustee or Certificate Administrator, as applicable,
pursuant to any of the provisions of this Section 8.07 shall not become effective until acceptance of appointment by the
successor Trustee or successor Certificate Administrator, as applicable, as provided in Section 8.08.

 

Upon the resignation,
assignment, merger, consolidation, or transfer of the Trustee or its business to a successor or upon the termination of the Trustee,
the outgoing Trustee shall (subject to the terms of the third paragraph of this Section 8.07) at its own expense, ensure
that prior to consummation of such action or as part of its transfer of duties to any successor (to the extent such Loan Document
was assigned or endorsed to the Trustee), (A) the original executed Note(s) for each Mortgage Loan, is endorsed (without recourse,
representation or

 

    	-320-

Trust, Commercial Mortgage Pass-Through Certificates, Series 2015-C4” or in blank and further showing a complete, unbroken
chain of endorsement from the originator (if such originator is not the applicable Mortgage Loan Seller) (or, alternatively, if
the original executed Note(s) have been lost, a lost note affidavit and indemnity with a copy of such Note(s)), and (B) in
the case of the other Mortgage Loan Documents, are assigned (and, other than in connection with the removal of 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 Mortgage Loan Documents identified in clause (B) of the preceding
sentence shall, if appropriate, be recorded by the successor trustee if so required by the Master Servicer or the Special Servicer
and at the expense of the Trust for so long as no Control Termination Event is continuing, with the consent of the Controlling
Class Representative, and during the continuance of a Control Termination Event, after consultation with the Controlling Class
Representative.

(a)            Any
successor Trustee or Certificate Administrator appointed as provided in Section 8.07 of this Agreement shall execute, acknowledge
and deliver to the Depositor, the Master Servicer, the Special Servicer and to the predecessor Trustee or Certificate Administrator,
as applicable, as the case may be, instruments accepting their appointment hereunder, and thereupon the resignation 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 rights, powers,

by a successor Trustee or Certificate Administrator, as applicable, as provided in this Section 8.08, the Depositor shall

notice within 10 days after

 

    	-321-

    	 

    

 

acceptance
of appointment by the successor Trustee or Certificate Administrator, 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 or 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 approved by the Trustee to act (at the expense of the Trustee) 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 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

 

    	-322-

    	 

    

 

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.

(a)           
The Certificate Administrator and the Custodian shall afford to any Privileged Person (including the Operating Advisor and
the Controlling Class Representative) access to any documentation (other than any Privileged Information) regarding the Mortgage

TERMINATION; OPTIONAL MORTGAGE LOAN PURCHASE

 

Section 9.01     Termination;
Optional Mortgage Loan Purchase.

 

(a)          The respective obligations and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating
Advisor, 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 to Certificateholders
as hereinafter set forth and to make any required remittances to the Serviced Companion Loan Holders in the month in which the
final Distribution Date occurs) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders
of the Controlling Class, the Special Servicer, the Master Servicer or the 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 voluntary 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 Trust Fund with respect to 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 for the period ending
with such termination, and shall maintain books and records with respect to the Trust REMICs 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 Principal Amount 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 neither such Holders nor the Special Servicer nor the Master Servicer does, any Holders of the

 

    	-326-

    	 

    

 

Class R Certificates
representing greater than a 50% Percentage Interest in such Class, may) effect an early termination of the Trust Fund, upon not
less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator, the Special Servicer
and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion Loan Holder provided for
in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in property acquired by the
Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum of (A) the aggregate
Purchase Price (excluding the amount described in clause (e) of the definition Purchase Price) of all the Mortgage
Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B) shall
be obtained by the Special Servicer and prepared by an Appraiser in accordance with MAI standards) and (C) 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 made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable, in connection with such purchase).

 

The Holders of the Controlling
Class representing greater than 50% of the Certificate Principal 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 neither such Holders nor
the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than a 50% Percentage
Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first notifies the Controlling
Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder of a Class R Certificate,
notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative, each Certifying Certificateholder
and the Master Servicer) of its intention to do so in writing within 30 days following the Early Termination Notice 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

 

    	-327-

    	 

    

 

Certificates,
and to the Trustee 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 Principal Balance of each such Certificate or Lower-Tier Regular
Interest, as the case may be, together with amounts required to be distributed on such Distribution Date pursuant to Section
4.01 of this Agreement or (ii) if no such Regular Certificates are then-outstanding, to the Holders of the Class R
Certificates of any amount remaining in the Collection Account, the Lower-Tier Distribution Account, the Upper-Tier Distribution
Account or the Excess Liquidation Proceeds Reserve Account, in either 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 and each Rating Agency (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 11.13 of this Agreement, the Rule 17g-5
Information Provider) at their addresses shown in the Certificate Register 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:

 

(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

 

    	-328-

    	 

    

 

contacting
Certificateholders shall be paid out of the assets which remain held. If within two years after the second notice any Certificates
shall not have been surrendered for cancellation, the Paying Agent shall pay, to the extent permitted by applicable law, 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, and then the Special Servicer, and then the Master
Servicer, and then the Holder of the Class R Certificates, in each of the last four cases, pursuant to subsection (c).

 

(h)          Following the date on which the Class X-A, Class X-B and Class X-D Notional Amounts and the aggregate Certificate
Principal Balance of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class A-S, Class B, Class C, Class D
and Class E Certificates are reduced to zero, the Remaining Certificateholder shall have the right to exchange all of its Certificates,
including the Class X Certificates (but excluding the Class R Certificates) for all of the Mortgage Loans (and if a Non-Serviced
Mortgage Loan is no longer a “Mortgage Loan” due to the fact that the related Mortgaged Property has been foreclosed
upon under the applicable Other Pooling and Servicing Agreement, the related REO Mortgage Loan) and each REO Property remaining
in the Trust Fund as contemplated by clause (ii) of Section 9.01(a) by giving written notice to all the
parties hereto no later than 60 days prior to the anticipated date of exchange; provided that such Remaining Certificateholder
shall pay the Master Servicer an amount equal to (i) the product of (A) the Prime Rate, (B) the aggregate Certificate Principal
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 its Certificates (other than the Class R Certificates)
for all of the Mortgage Loans and each REO Property 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, 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 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
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 Companion Loan Holders, sending of certain notices, preparing and filing tax returns and maintenance
of books

 

    	-329-

    	 

    

 

and records),
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 Principal Balance of its
remaining Certificates (other than the 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 are deemed distributed to the Remaining Certificateholder in liquidation of the
Trust Fund pursuant to this Section 9.01.

EXCHANGE ACT REPORTING AND REGULATION AB COMPLIANCE

 

Section 10.01     Intent
of the Parties; Reasonableness.

 

(a)          The parties hereto acknowledge and agree that the purpose of Article X of this Agreement is to facilitate compliance
by the Depositor and any Other Depositor with the provisions of Regulation AB and the related rules and regulations of the Commission.
The Depositor shall not, and no Other Depositor may, exercise its rights to request delivery of information or other performance
under these provisions other than in good faith, or for purposes other than compliance with the Securities Act, the Exchange Act
and the Sarbanes-Oxley Act. The parties hereto acknowledge that interpretations of the requirements of Regulation AB may change
over time due to interpretive guidance provided by the Commission or its staff, and agree to comply with reasonable requests made
by the Depositor, or any Other Depositor, in good faith for delivery of information under these provisions on the basis of such
evolving interpretations of Regulation AB. In connection with the CSAIL 2015-C4 Commercial Mortgage Trust, Commercial Mortgage
Pass-Through Certificates, Series 2015-C4, and any Serviced Companion Loan Securities, each of the parties to this Agreement shall
cooperate fully with the Depositor and the Certificate Administrator, any Other Depositor and any Other Exchange Act Reporting
Party, as applicable, to deliver to the Depositor or Other Depositor, as applicable (including any of its assignees or designees),
any and all statements, reports, certifications, records and any other information in its possession or reasonably available to
it and necessary in the reasonable good faith determination of the Depositor or the Certificate Administrator, any Other Depositor
or any Other Exchange Act Reporting Party, as applicable, to permit the Depositor or any Other Depositor, as applicable, to comply
with the provisions of Regulation AB, together with such disclosures relating to the Master Servicer, the Special Servicer, the
Operating Advisor, the Custodian, the Certificate Administrator and the Trustee, as applicable, and any Sub-Servicer, or the servicing
of the Mortgage Loans, reasonably believed by the Depositor or any Other Depositor, as applicable, to be necessary in order to
effect such compliance.

 

(b)          Succession; Subcontractors Reasonableness. 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 10.06 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” as contemplated by Item 1108(a)(2) of Regulation AB) under this Agreement
by any Person (i) into which the Master Servicer, the

 

    	-330-

or such Sub-Servicer may be merged or consolidated, or (ii) which may be appointed as a successor to the Master Servicer,
the Special Servicer or any such Sub-Servicer, the Master Servicer (other than if pursuant to an appointment under Section
7.01 or Section 7.02 of this Agreement) or the Special Servicer, as applicable, 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, and otherwise no later than one (1) Business Day after such effective date
of succession, (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 Depositor, all information relating
to such successor servicer reasonably requested by the Depositor or any such Other Depositor in order to comply with its reporting
obligation under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports under the Exchange Act are required
to be filed under the Exchange Act).

 

(c)          For so long as the Trust or any Other Securitization Trust is subject to the reporting requirements of the Exchange Act,
each of the Master Servicer, the Special Servicer, the Sub-Servicer, the Custodian and the Certificate Administrator (each of the
Master Servicer, the Special Servicer, the Custodian and the Certificate Administrator and each Sub-Servicer, for purposes of this
Section 10.01(c) and Section 10.01(d), a “Servicer”) is permitted to utilize one or more Subcontractors
to perform certain of its obligations hereunder. Such Servicer shall promptly upon request provide to the Depositor, as well as
any Other Depositor as to which the applicable Companion Loan is affected, a written description (in form and substance satisfactory
to the Depositor and each such Other Depositor) of the role and function of each Subcontractor that is a Servicing Function Participant
utilized by such Servicer during the preceding calendar year, specifying (i) the identity of such Subcontractor, and (ii) which
elements of the Servicing Criteria will be addressed in assessments of compliance provided by each such Subcontractor. Each Servicer
shall cause any Subcontractor determined to be a Servicing Function Participant used by such Servicer for the benefit of the Depositor
to comply with the provisions of Section 10.08 and Section 10.09 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 10.08 and Section 10.09 of this Agreement, in each case, as and when required to be delivered.

 

(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, 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 such Subcontractor shall be deemed to be a Sub-Servicer for purposes of this Agreement, and the engagement of such Sub-Servicer
shall not be effective unless and until notice is given to the Depositor and the Certificate Administrator, as well as any Other
Depositor as to which the

 

    	-331-

    	 

    

 

applicable
Companion Loan is affected, of any such Sub-Servicer and Sub-Servicing Agreement. No Sub-Servicing Agreement (other than such
agreements set forth on Exhibit S hereto) shall be effective until five (5) Business Days after such written notice
is received by the Depositor and the Certificate Administrator and each such Other Depositor. 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 Companion Loan is affected, to accurately and timely report the event under Item
6.02 of Form 8-K pursuant to Section 10.06 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
10.06 of this Agreement) and shall furnish pursuant to Section 10.06 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
reasonably necessary for the Certificate Administrator and Trustee and each Other Exchange Act Reporting Party to accurately and
timely report, the event under Item 6.02 of Form 8-K pursuant to Section 10.06 of this Agreement (if such reports under
the Exchange Act are required to be filed under the Exchange Act).

 

Section 10.02     Filing Obligations.

 

(a)          The Master Servicer, the Special Servicer, 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 10.03, Section 10.04 and Section 10.06, the Certificate Administrator shall prepare
for execution by the Depositor any Forms 10-D, 10-K and 8-K required by the Exchange Act, in order to permit the timely filing
thereof, and the Certificate Administrator shall file (via the Commission’s Electronic Data Gathering and Retrieval System)
such Forms executed by the Depositor. 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 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 and 10-K,

 

    	-332-

    	 

    

 

the Depositor
and the Certificate Administrator will thereupon cooperate to prepare and file a Form 12b-25 and a Form 10-D/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 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. Any Form 12b-25
or any amendment to Form 8-K, Form 10-D 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 10.02
related to the timely preparation and filing of Form 12b-25 or any amendment to Form 8-K, Form 10-D 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 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 or Form 10-K, not resulting from its own negligence,
bad faith or willful misconduct.

 

Section 10.03     Form
10-D Filings.

 

Within 15 calendar days
after each Distribution Date (subject to permitted extensions under the Exchange Act), the Certificate Administrator shall prepare
and file on behalf of the Trust any Form 10-D then required by the Exchange Act, in form and substance as then required by
the Exchange Act. The Certificate Administrator shall file each Form 10-D with a copy of the related Distribution Date Statement
attached thereto; provided that the Certificate Administrator shall redact from such Distribution Date Statement any information
relating to the ratings of the Certificates and the identity of the Rating Agencies. Any disclosure in addition to the Distribution

Depositor, the Certificate Administrator and each Other Depositor and Other Exchange Act Reporting Party to which such Additional
Form 10-D Disclosure is relevant for Exchange Act reporting purposes and (ii) approved by the Depositor and each such Other

Trust is subject to the reporting requirements of the Exchange Act, within one (1) Business Day after the related Distribution
Date (using commercially reasonable efforts), but in no event later than noon (New York City time) on the third Business Day after
the related Distribution Date, (i) certain parties to this Agreement, as set forth on Exhibit U to this Agreement,

    	-333-

Disclosure is relevant for Exchange Act reporting purposes, to the extent a Servicing Officer or Responsible Officer thereof has
knowledge thereof (other than information required by Item 1117 of Regulation AB as to such party which shall be reported
if actually known by any Servicing Officer or Responsible Officer, as the case may be or any lawyer in the in-house legal department
of such party) in EDGAR-Compatible Format (to the extent available to such party in such format), or in such other format as otherwise
agreed upon by the Certificate Administrator, the Depositor and each such Other Exchange Act Reporting Party, each such Other
Depositor and such parties, the form and substance of the Additional Form 10-D Disclosure, if applicable, (ii) the parties
listed on Exhibit U to this Agreement shall include with such Additional Form 10-D Disclosure application to
such party and shall cause each Sub-Servicer (or, in the case of each Sub-Servicer set forth on Exhibit S, shall use
commercially reasonable efforts to cause such Sub-Servicer) and Subcontractor of such party to the extent required under Regulation AB
to provide, and if received, include, an Additional Disclosure Notification in the form attached as Exhibit W to this
Agreement and (iii) the Depositor shall approve, as to form and substance, or disapprove, as the case may be, the inclusion
of the Additional Form 10-D Disclosure on Form 10-D. 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 information. The Depositor
will be responsible for any reasonable fees assessed or expenses incurred by the Certificate Administrator in connection with
including any Additional Form 10-D Disclosure on Form 10-D pursuant to this paragraph.

 

The Certificate Administrator
shall include in any Form 10-D filed by it with respect to the Trust (i) the information required by Rule 15Ga-1(a)
of the Exchange Act concerning all assets of the Trust that were subject of a demand for the repurchase of, or the substitution
of a Qualified Substitute Mortgage Loan for, a Mortgage Loan contemplated by Section 2.03(a) of this Agreement, (ii) a
reference to the most recent Form ABS-15G filed by the Depositor and the Commission’s assigned “Central Index Key”
for the Depositor, which information the Depositor shall deliver to the Certificate Administrator, and (iii) a reference to
the most recent Form ABS-15G filed by each Mortgage Loan Seller and the Commission’s assigned “Central Index Key”

(a)          After preparing the Form 10-D, the Certificate Administrator shall forward electronically a copy of the Form 10-D
to the Depositor for review. Within two (2) Business Days after receipt of such copy, but no later than the 9th calendar
day after the related Distribution Date or, if the 9th calendar day after the related Distribution Date is not a Business
Day, the immediately preceding Business Day, the Depositor shall notify the Certificate Administrator in writing (which may be
furnished electronically) of any changes to or approval of such Form 10-D. Within two (2) Business Days after receipt of such
copy, but no later than two (2) Business Days prior to the 15th calendar day after the related Distribution Date, an
officer of the Depositor shall sign the Form 10-D and return an electronic or fax copy of such signed Form 10-D (with
an original executed hard copy to follow by overnight mail) to the Certificate Administrator. Upon receipt of such signed Form 10-D
(in electronic form or by fax copy), the Certificate Administrator shall deem such report to be approved by the Depositor and shall
proceed with filing such report with the Commission. If a Form 10-D cannot be filed on time or

 

    	-334-

    	 

    

 

if a previously
filed Form 10-D needs to be amended, the Certificate Administrator will follow the procedures set forth in Section 10.02(a)

of its duties under this Section 10.03 related to the timely preparation and filing of Form 10-D is contingent upon
such parties observing all applicable deadlines in the performance of their duties under this Section 10.03. 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 such Form 10-D, where such failure results because required disclosure
information was either not delivered to the Certificate Administrator or delivered to the Certificate Administrator after the
delivery deadlines set forth in this Agreement, not resulting from its own negligence, bad faith or willful misconduct.

 

(b)          Form 10-D requires the registrant to indicate (by checking “yes” or “no”) that it “(1)

such shorter period that the registrant was required to file such reports), and (2) has been subject to such filing requirements
for the past 90 days.” The Depositor hereby instructs the Certificate Administrator, with respect to each Form 10-D,
to check “yes” for each item unless the Certificate Administrator has received prior written notice (which may be furnished
electronically) from the Depositor that the answer should be “no” for an item which notice shall be delivered to the
Certificate Administrator no later than the day on which the Depositor provided its signature for such filing pursuant to Section
10.03(a) of this Agreement.

(a)          Within 90 days after the end of each fiscal year of the Trust (it being understood that the fiscal year of the Trust

by the Certificate Administrator of its duties under this Section 10.04 related to the timely preparation and filing of
Form 10-K is contingent upon the parties to this Agreement (and any Additional Servicer or Servicing Function Participant
engaged or utilized, as applicable, by any such parties) observing all applicable deadlines in the performance of their duties
under this Section 10.04. The Certificate Administrator shall have no liability for any loss, expense, damage, claim arising
out of or with respect to any failure to properly prepare, arrange for execution and/or timely file such Form 10-K, where
such failure results because required disclosure information was either not delivered to the Certificate Administrator or delivered

bad faith or willful misconduct.

 

(b)          Form 10-K requires the registrant to indicate (by checking “yes” or “no”) that it “(1)

10.04(a) of this Agreement.

 

Section 10.05     Sarbanes-Oxley Certification. Each Form 10-K shall include a Sarbanes-Oxley Certification in the form attached
to this Agreement as Exhibit X required to be included therewith pursuant to the Sarbanes-Oxley Act. The Certificate

any Servicing Function Participant of such party that is a Mortgage Loan Seller Sub-Servicer, shall use commercially reasonable
efforts to cause such Servicing Function Participant to provide, and (ii) with respect to any other Servicing Function Participant

on which the Certifying Person, the entity for which the Certifying Person acts as an officer, and such entity’s officers,
directors and Affiliates (collectively with the Certifying Person, “Certification Parties”) can reasonably
rely. With respect to any Non-Serviced Mortgage Loan serviced under the related Other Pooling and Servicing Agreement, the Certificate
Administrator will use commercially reasonable efforts to procure a Sarbanes-Oxley back-up certification similar in form and substance
to the applicable certification from the related Other Master Servicer, the related Other Special Servicer, the related Other
Paying Agent and the related Other Trustee. In the event any Reporting Servicer is terminated or resigns pursuant to the terms
of this Agreement, or any applicable Sub-Servicing Agreement or primary servicing agreement, as the case may be, such Reporting
Servicer shall provide a certification to the Certifying Person pursuant to this Section 10.05 with respect to the period
of time it was subject to this Agreement or the applicable sub-servicing or primary servicing agreement, as the case may be.

 

Section 10.06     Form
8-K Filings. Within four (4) Business Days after the occurrence of an event requiring disclosure on Form 8-K (each such
event, a “Reportable Event”), and if requested by the Depositor, the Certificate Administrator shall prepare
and file on behalf of the Trust any Form 8-K, as required by the Exchange Act and shall provide notice thereof to Form10K.Compliance@cwt.com,
provided that the Depositor shall file the initial Form 8-K in connection with the issuance of the Certificates. Any

the applicable parties set forth on Exhibit Z to this Agreement to the Depositor, the Certificate Administrator, and
each Other Depositor and Other Exchange Act Reporting Party to which such Form 8-K Disclosure Information is relevant for Exchange
Act reporting purposes, and the Certificate Administrator will have no duty or liability for any failure hereunder to determine

Reporting Party shall use reasonable efforts to keep the Depositor informed of its progress with the Commission or its staff and
copy the Depositor on all correspondence with the Commission or its staff and provide the Depositor with the opportunity to participate
(at the Depositor’s expense) in any telephone conferences and meetings with the Commission or its staff and (ii) the Depositor

Certificate Administrator, the Trustee, the Additional Servicer or other Servicing Function Participant (the “Performing
Party”) shall contribute to the amount paid or payable to the indemnified party as a result of the losses, claims, damages
or liabilities of the indemnified party in such proportion as is appropriate to reflect the relative fault of the indemnified party

to Section 10.05, Section 10.07, Section 10.08, or Section 10.09 (or breach of its obligations under
the applicable sub-servicing or primary servicing agreement to provide any of the annual compliance statements or annual servicing
criteria compliance reports or attestation reports) or the Performing Party’s negligence, bad faith or willful misconduct
in connection therewith. The Master Servicer, the Special Servicer and the Certificate Administrator shall cause each Servicing
Function Participant of such party that is not a Mortgage Loan Seller Sub-Servicer (and with respect to any Servicing Function
Participant of such party that is a Mortgage Loan Seller Sub-Servicer, shall use commercially reasonable efforts to cause such
Servicing Function Participant) to agree to the foregoing indemnification and contribution obligations. This Section 10.11

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 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

as applicable, own rights, duties or immunities under this Agreement. The party requesting an amendment to this Agreement shall,

in and to the Mortgage Loans pursuant to this Agreement shall constitute a sale and not a pledge of security for a loan. If such
conveyance is deemed to be a pledge of security for a loan, however, the Depositor intends that the rights and obligations of the
parties to such loan shall be established pursuant to the terms of this Agreement. The Depositor also intends and agrees that,
in such event, (i) the Depositor shall be deemed to have granted to the Trustee (in such capacity) a first priority security
interest in the Depositor’s entire right, title and interest in and to the assets comprising the Trust Fund, including without
limitation, the Mortgage Loans, all principal and interest received or receivable with respect to the Mortgage Loans (other than
principal and interest payments due and payable prior to the Cut-Off Date and Principal Prepayments received prior to the Cut-Off
Date), all amounts held from time to time in the Collection Account, each 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 11.08 shall constitute
notice to the Trustee pursuant to any of the requirements of the applicable UCC.

heading of
“CSAIL 2015-C4” and sufficient detail to indicate that such information is required to be posted on the Rule 17g-5
Information Provider’s Website. In connection with notifying a Registered Rating Agency of any information posted to the Rule 17g-5
Information Provider’s Website, the Rule 17g-5 Information Provider shall only be responsible for sending such notices to
the electronic mail address 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 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 mail address of any Registered Rating Agency that
is not provided to the Rule 17g-5 Information in the manner described in this sentence.

 

The 17g-5 Information
Provider shall make available, only to the Depositor and NRSROs, the Rating Agency Q&A Forum and Document Request Tool. The
“Rating Agency Q&A Forum and Document Request Tool” shall be a service available on the 17g-5 Information
Provider’s Website, where NRSROs may (i) submit questions to the Certificate Administrator relating to any Distribution Date
Statements, or submit questions to the Master Servicer or the Special Servicer, as applicable, relating to the reports prepared
by such parties (each such submission, a “Rating Agency Inquiry”), and (ii) view Rating Agency Inquiries that
have been previously submitted and answered, together with the responses thereto. In addition, NRSROs may use the forum to submit
requests (each such submission also, a “Rating Agency Inquiry”) to the Master Servicer for loan-level reports and other
related information. Upon receipt of a Rating Agency Inquiry for the Master Servicer or the Special Servicer, the 17g-5 Information
Provider shall forward the Rating Agency Inquiry to the appropriate person, in each case within a commercially reasonable period
of time following receipt thereof. Following receipt of a Rating Agency Inquiry from the 17g-5 Information Provider, the Master
Servicer or the Special Servicer, as applicable, unless it determines not to answer such Rating Agency Inquiry as provided below,
shall reply by email to the 17g-5 Information Provider. The 17g-5 Information Provider shall post (within a commercially reasonable
period of time following receipt of such response) such Rating Agency Inquiry with the related response thereto (or such reports,
as applicable) to the Rating Agency Q&A Forum and Document Request Tool. Any reports posted by the 17g-5 Information Provider
in response to an inquiry may be posted on a separate website or web page accessible by a link on the 17g-5 Information Provider’s
Website. If the Certificate Administrator, the Trustee, the Master Servicer or the Special Servicer determines, in its respective
sole discretion, that (i) answering any Rating Agency Inquiry would be in violation of applicable law, the Servicing Standard,
this Agreement or any Mortgage Loan documents, (ii) answering any Rating Agency Inquiry would or is reasonably expected to result
in a waiver of an attorney-client privilege, or the disclosure of attorney work product, or (iii) (A) answering any Rating Agency
Inquiry would materially increase the duties of, or result in significant additional cost or expense to, the Certificate Administrator,
the Trustee, the Master Servicer or the Special Servicer, as applicable, and (B) the Certificate Administrator, the Trustee, the
Master Servicer or the Special Servicer, as applicable, determines in accordance with the Servicing Standard (or in good faith,
in the case of the Trustee) that the performance of such duties or the payment of such costs and expenses is beyond the scope of
its duties in its capacity as Certificate Administrator, Trustee, Servicer or Special Servicer, as applicable, under this Agreement,
it shall not be required to answer such Rating Agency Inquiry and shall promptly notify the 17g-5 Information Provider by email
of such determination. The 17g-5 Information Provider shall promptly

 

    	-368-

    	 

    

 

thereafter
post the Rating Agency Inquiry with the reason it was not answered to the Rating Agency Q&A Forum and Document Request Tool.
The 17g-5 Information Provider will not be liable for the failure by any other such Person to so answer. Questions posted on the
Rating Agency Q&A Forum and Document Request Tool shall not be attributed to the submitting NRSRO. Answers posted on the Rating
Agency Q&A Forum and Document Request Tool will be attributable only to the respondent, and shall not be deemed to be answers
from any other person. None of the Initial Purchasers, the Depositor, nor any of their respective Affiliates will certify to any
of the information posted in the Rating Agency Q&A Forum and Document Request Tool and no such party shall have any responsibility
or liability for the content of any such information. The 17g-5 Information Provider shall not be required to post to the 17g-5
Information Provider’s Website any Rating Agency Inquiry or answer thereto that the 17g-5 Information Provider determines,
in its sole discretion, is administrative or ministerial in nature. The Rating Agency Q&A Forum and Document Request Tool
will not reflect questions, answers and other communications that are not submitted via the 17g-5 Information Provider’s
Website.

 

(k)          In connection with the delivery by the Master Servicer or the Special Servicer 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 provide electronic confirmation to the Master Servicer or the Special Servicer, as applicable, of when
such information, report, notice or other document has been posted to the Rule 17g-5 Information Provider’s Website,
and, except as provided in Section 11.13(d), the Master Servicer or the Special Servicer, as applicable, may (but is not
obligated to) send such information, report, notice or other document to the applicable Rating Agency so long as such information,
report, notice or document was (i) previously provided to the Rule 17g-5 Information Provider or (ii) is simultaneously provided
to the Rule 17g-5 Information Provider.

 

Section 11.14     Cooperation with the Mortgage Loan Sellers with Respect to Rights Under the Loan Agreements. It is expressly agreed
and understood that, notwithstanding the assignment of the Mortgage Loan Documents, it is expressly intended that the Mortgage
Loan Sellers get the benefit of any securitization indemnification provisions in the Mortgage Loan Documents. Therefore, the Depositor,
Master Servicer, Special Servicer and Trustee hereby agree to reasonably cooperate with any Mortgage Loan Seller at the sole reasonable
expense of such Mortgage Loan Seller with respect to the benefits of the provisions of any section of a Loan Agreement or securitization
cooperation agreement related to indemnification of the lender and/or its affiliates with respect to any 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 Mortgage Loan Documents, to permit the related Mortgage Loan Seller and its respective affiliates to enforce
such provisions for their respective benefits; 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 Mortgage Loan Documents, would adversely affect any Certificateholder, would cause
either Trust REMIC to fail to qualify as a REMIC 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 11.14, such document shall be in form and substance
reasonably acceptable to the Trustee.

This certifies that

and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the

the meanings assigned thereto in the Pooling and Servicing Agreement.

 

This Certificate represents

in Sections 860G(a)(1) and 860D of the Internal Revenue Code of 1986, as amended.

 

The Certificate Administrator

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 that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-1 Certificates

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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if

 

    	A-1-3

    	 

    

 

such
Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business Days prior to the
related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate Administrator
or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice
to Certificateholders of such 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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each

 

    	A-1-4

    	 

    

 

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 on behalf of the Trust in any environmental indemnity agreements relating to the
Mortgaged Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee
pursuant to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 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
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 

 

    	A-1-5

    	 

    

 

	 	 	affect in any material respect the interests of any Certificateholder or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) reduce the consultation rights or the right to receive

 

    	A-1-6

    	 

    

 

information
under the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (iii) change
in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable
Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely
affect any 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, Special Servicer or Trustee is requesting an
amendment for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

 

		(iv)	change the definition of “Servicing Standard” without either (1) consent of 100% of
the holders of the Certificates or (2) 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 

 

    	A-1-7

    	 

    

 

	 	 	of the Certificateholders to terminate the Operating Advisor
pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer)

 

    	A-1-8

    	 

    

 

of
its intention to do so in writing within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-3, Class A-4, Class A-SB, Class X-A, Class

 

    	A-2-2

    	 

    

 

X-B,
Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F, Class G, Class NR and Class
R Certificates (together with the Class A-2 Certificates, the “Certificates”; the Holders of Certificates issued
under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-2 Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if

 

    	A-2-3

    	 

    

 

such
Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business Days prior to the
related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate Administrator
or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice
to Certificateholders of such 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. 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

interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust under any indemnities or guaranties given as additional security for any Mortgage Loan; (viii) all

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 on behalf of the Trust in any environmental indemnity agreements relating to the

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 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
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement or to correct
any error;

adversely 

 

    	A-2-5

    	 

    

 

	 	 	affect in any material respect the interests of any Certificateholder or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) reduce the consultation rights or the right to receive

 

    	A-2-6

    	 

    

 

information
under the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (iii) change
in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable
Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely
affect any 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, Special Servicer or Trustee is requesting an
amendment for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

 

		(iv)	change the definition of “Servicing Standard” without either (1) consent of 100% of
the holders of the Certificates or (2) 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 

 

    	A-2-7

    	 

    

 

	 	 	of the Certificateholders to terminate the Operating Advisor
pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer)

 

    	A-2-8

    	 

    

 

of
its intention to do so in writing within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-4, Class A-SB, Class X-A, Class

 

    	A-3-2

    	 

    

 

X-B,
Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F,
Class G, Class NR and Class R Certificates (together with the Class A-3 Certificates, the “Certificates”; the
Holders of Certificates issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-3 Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class A-3 Certificates is the calendar
month preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if

 

    	A-3-3

    	 

    

 

such
Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business Days prior to the
related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate Administrator
or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice
to Certificateholders of such 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. 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

the Operating Advisor, 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
or any Serviced Companion Loan Holder;

of the Pooling and Servicing Agreement or with the description thereof in the Prospectus or the Prospectus Supplement or to correct
any error;

adversely 

 

    	A-3-5

    	 

    

 

	 	 	affect in any material respect the interests of any Certificateholder or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) reduce the consultation rights or the right to receive

 

    	A-3-6

    	 

    

 

information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase
Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely affect
any 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, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

the holders of the Certificates or (2) 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 

 

    	A-3-7

    	 

    

 

	 	 	of the Certificateholders to terminate the Operating Advisor
pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer)

 

    	A-3-8

    	 

    

 

of
its intention to do so in writing within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-SB, Class X-A, Class

 

    	A-4-2

    	 

    

 

X-B,
Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F,
Class G, Class NR and Class R Certificates (together with the Class A-4 Certificates, the “Certificates”; the
Holders of Certificates issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-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 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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if

 

    	A-4-3

    	 

    

 

such
Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business Days prior to the
related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate Administrator
or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice
to Certificateholders of such 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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each

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 on behalf of the Trust in any environmental indemnity agreements relating to the
Mortgaged Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee
pursuant to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

This Certificate does

	 	 	affect in any material respect the interests of any Certificateholder or Serviced Companion Loan Holder, 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

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 or, if applicable, any Serviced Companion Loan Holder, (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

the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

interests of any Certificateholder or, if applicable any Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) reduce the consultation rights or the right to receive

 

    	A-4-6

    	 

    

 

information under
the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase
Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely affect
any 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, Special Servicer or Trustee is requesting an amendment

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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

the holders of the Certificates or (2) 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 

 

    	A-4-7

    	 

    

 

	 	 	of the Certificateholders to terminate the Operating Advisor
pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer)

 

    	A-4-8

    	 

    

 

of
its intention to do so in writing within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class A-SB Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial, multifamily and manufactured
housing community properties and held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class X-A, Class

 

    	A-5-2

    	 

    

 

X-B,
Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F,
Class G, Class NR and Class R Certificates (together with the Class A-SB Certificates, the “Certificates”;
the Holders of Certificates issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-SB Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if

 

    	A-5-3

    	 

    

 

such
Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business Days prior to the
related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate Administrator
or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice
to Certificateholders of such 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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each

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 on behalf of the Trust in any environmental indemnity agreements relating to the
Mortgaged Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee
pursuant to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or,
as applicable, any Companion Loan Holder:

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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

the holders of the Certificates or (2) 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 

 

    	A-5-7

    	 

    

 

	 	 	of the Certificateholders to terminate the Operating Advisor
pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer)

 

    	A-5-8

    	 

    

 

of
its intention to do so in writing within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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
E, Class F, Class G, Class NR and Class R 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-A Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner,

 

    	A-6-4

    	 

    

 

but
only upon presentment and surrender of such Certificate at the office of the Certificate Administrator or its agent (which may
be the Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice to Certificateholders of
such 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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each 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 on behalf of the Trust in any environmental indemnity agreements relating to the

 

    	A-6-5

    	 

    

 

Mortgaged
Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee pursuant
to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 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
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 or Serviced Companion Loan Holder, as evidenced
by an opinion of counsel (at the expense of the party requesting the amendment);

 

    	A-6-6

    	 

    

 

		(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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) 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; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase

any manner the obligations or rights of any
Underwriter or Initial Purchaser, without the consent of the affected Underwriter or Initial Purchaser; or (v) adversely affect
any 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, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

 

		(iv)	change the definition of “Servicing Standard” without either (1) consent of 100% of
the holders of the Certificates or (2) 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;

 

    	A-6-8

    	 

    

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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

 

    	A-6-9

    	 

    

 

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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A, Class
X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F, Class G, Class NR and Class R Certificates
(together with the Class X-B Certificates, the “Certificates”; the Holders of Certificates are collectively
referred to herein as “Certificateholders”).

 

    	A-7-3

    	 

    

 

This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-B Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such final distribution.

 

    	A-7-4

    	 

    

 

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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each 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 on behalf of the Trust in any environmental indemnity agreements relating to the Mortgaged
Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee pursuant
to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

    	A-7-5

    	 

    

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 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
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 or Serviced Companion Loan Holder, 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 to
avoid or minimize the risk of imposition of any tax on the

 

    	A-7-6

    	 

    

 

	 	 	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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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,

Agreement; and

 

		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary

amendment shall be
borne by the party requesting such amendment, unless the Master Servicer, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate Percentage Interests of each Class of Certificates affected

consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and

the holders of the Certificates or (2) 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 any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; or

 

    	A-7-8

    	 

    

 

		(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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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-F 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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A, Class
X-B, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F, Class G, Class NR and Class R Certificates
(together with the Class X-F 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-F Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related

 

    	A-8-4

    	 

    

 

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-F 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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such 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. 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); (iii) any REO

 

    	A-8-5

    	 

    

 

Property
(but in the case of each Whole Loan, only to the extent of the Trust’s interest in the related REO Property); (iv) all revenues
received in respect of any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s interest
in the revenues received in respect of such REO Property); (v) the Master Servicer’s and the Trustee’s rights, in
each case on behalf of the Trust, 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 on behalf of the Trust in any
Assignment of Leases and any security agreements; (vii) the Trustee’s rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts and Lockbox Accounts and all proceeds of the Mortgage Loans
deposited in the Collection Account, each 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 on behalf of the
Trust in any environmental indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under
the Loan Purchase Agreements to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing
Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or,
as applicable, any Companion Loan Holder:

 

    	A-8-6

    	 

    

 

		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates
or any Serviced Companion Loan Holder;

Agreement; and

Loan Holder;

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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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-8-8

    	 

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and

Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included

 

    	A-8-9

    	 

    

 

in
the Trust Fund, and all property or interests in property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase
price, payable in cash, equal to (i) the sum of (A) the aggregate Purchase Price (excluding the amount described in clause (e)
of the definition of Purchase Price) of all the Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B)
the Appraised Value of the Trust’s portion of each REO Property, if any, included in the Trust Fund, as determined by the
Special Servicer (such Appraisals in clause (i)(B) shall be obtained by the Special Servicer) and (C) 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 made by such party, 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 purchasing
Master Servicer or the Special Servicer, as applicable, in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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

 

    	A-8-10

    	 

    

 

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 thereby 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-G 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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A, Class
X-B, Class X-F, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F, Class G, Class NR and Class R Certificates
(together with the Class X-G 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-G Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related

 

    	A-9-4

    	 

    

 

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-G 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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such 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. 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); (iii) any REO

 

    	A-9-5

    	 

    

 

Property
(but in the case of each Whole Loan, only to the extent of the Trust’s interest in the related REO Property); (iv) all revenues
received in respect of any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s interest
in the revenues received in respect of such REO Property); (v) the Master Servicer’s and the Trustee’s rights, in
each case on behalf of the Trust, 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 on behalf of the Trust in any
Assignment of Leases and any security agreements; (vii) the Trustee’s rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts and Lockbox Accounts and all proceeds of the Mortgage Loans

the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate

the Operating Advisor, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or,
as applicable, any Companion Loan Holder:

 

    	A-9-6

    	 

    

 

		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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,

 

    	A-9-7

    	 

    

 

	 	 	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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) 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; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase
Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely affect
any 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, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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-9-8

    	 

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

the holders of the Certificates or (2) 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 any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included

 

    	A-9-9

    	 

    

 

in
the Trust Fund, and all property or interests in property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase
price, payable in cash, equal to (i) the sum of (A) the aggregate Purchase Price (excluding the amount described in clause (e)
of the definition of Purchase Price) of all the Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B)
the Appraised Value of the Trust’s portion of each REO Property, if any, included in the Trust Fund, as determined by the
Special Servicer (such Appraisals in clause (i)(B) shall be obtained by the Special Servicer) and (C) 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 made by such party, 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 purchasing
Master Servicer or the Special Servicer, as applicable, in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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

 

    	A-9-10

    	 

    

 

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 thereby 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-NR 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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A, Class
X-B, Class X-F, Class X-G, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F, Class G, Class NR and Class R Certificates
(together with the Class X-NR 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-NR Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related

 

    	A-10-4

    	 

    

 

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-NR 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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such 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. 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

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); (iii) any REO

 

    	A-10-5

    	 

    

 

Property
(but in the case of each Whole Loan, only to the extent of the Trust’s interest in the related REO Property); (iv) all revenues
received in respect of any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s interest
in the revenues received in respect of such REO Property); (v) the Master Servicer’s and the Trustee’s rights, in
each case on behalf of the Trust, 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 on behalf of the Trust in any
Assignment of Leases and any security agreements; (vii) the Trustee’s rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts and Lockbox Accounts and all proceeds of the Mortgage Loans
deposited in the Collection Account, each 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 on behalf of the
Trust in any environmental indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under
the Loan Purchase Agreements to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing
Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or,
as applicable, any Companion Loan Holder:

 

    	A-10-6

    	 

    

 

		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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,

 

    	A-10-7

    	 

    

 

	 	 	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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) 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; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase
Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely affect
any 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, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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-10-8

    	 

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

 

		(iv)	change the definition of “Servicing Standard” without either (1) consent of 100% of
the holders of the Certificates or (2) 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 any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the Companion Loan Holders) any time on or

than all, of the Mortgage Loans (and in the case of the Serviced Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included

 

    	A-10-9

    	 

    

 

in
the Trust Fund, and all property or interests in property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase

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 made by such party, 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 purchasing
Master Servicer or the Special Servicer, as applicable, in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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 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 to Certificateholders as set forth in the Pooling and Servicing

(or interests therein) then included in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii)
the voluntary 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

 

    	A-10-10

    	 

    

 

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 thereby continue beyond the expiration of twenty-one years from the death

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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A,
Class X-B, Class X-F, Class X-G, Class X-NR, Class B, Class C, Class D, Class X-

 

    	A-11-2

    	 

    

 

D,
Class E, Class F, Class G, Class NR and Class R Certificates (together with the Class A-S Certificates, the “Certificates”;
the Holders of Certificates issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-S Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less

 

    	A-11-3

    	 

    

 

than
five Business Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of
the Certificate Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that
is specified in the notice to Certificateholders of such 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. 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

    	A-11-5

    	 

    

 

	 	 	Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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

will not adversely affect in any material respect the interests of any Certificateholder or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) reduce the consultation rights or the right to receive information under
the Pooling and Servicing Agreement of the Operating Advisor without the

manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase

borne by the party requesting such amendment, unless the Master Servicer, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and

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 

 

    	A-11-7

    	 

    

 

	 	 	of the Certificateholders to terminate the Operating Advisor
pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; or

The Holders of the
Controlling Class representing greater than 50% of the Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)

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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer)

 

    	A-11-8

    	 

    

 

of
its intention to do so in writing within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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

(together with the Class B Certificates, the “Certificates”; the Holders of Certificates issued under the Pooling
and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class B Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if

 

    	A-12-3

    	 

    

 

such
Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business Days prior to the
related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each Certificate shall
be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate Administrator
or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice
to Certificateholders of such 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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each

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 on behalf of the Trust in any environmental indemnity agreements relating to the
Mortgaged Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee

adversely 

 

    	A-12-5

    	 

    

 

	 	 	affect in any material respect the interests of any Certificateholder or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) reduce the consultation rights or the right to receive

 

    	A-12-6

    	 

    

 

information
under the Pooling and Servicing Agreement of the Operating Advisor without the consent of the Operating Advisor; (iii) change
in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable
Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely
affect any 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, Special Servicer or Trustee is requesting an
amendment for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

the holders of the Certificates or (2) 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 

 

    	A-12-7

    	 

    

 

	 	 	of the Certificateholders to terminate the Operating Advisor
pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer)

 

    	A-12-8

    	 

    

 

of
its intention to do so in writing within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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
NR and Class R Certificates (together with the Class C Certificates, the “Certificates”; the Holders of Certificates
issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class C Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less

 

    	A-13-3

    	 

    

 

than
five Business Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution
on each Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of
the Certificate Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that
is specified in the notice to Certificateholders of such 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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each Distribution Account, the
Interest Reserve Account, the Excess Liquidation Proceeds Reserve

 

    	A-13-4

    	 

    

 

Account
and any REO Account, including any reinvestment income thereon; (ix) the Trustee’s rights on behalf of the Trust in any
environmental indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s rights under the Loan
Purchase Agreements to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement
and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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,

Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and

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 

 

    	A-13-7

    	 

    

 

	 	 	of the Certificateholders to terminate the Operating Advisor
pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer)

 

    	A-13-8

    	 

    

 

of
its intention to do so in writing within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

with the Class D Certificates, the “Certificates”; the Holders of Certificates issued under the Pooling and
Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class D Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder

 

    	A-14-3

    	 

    

 

at
a bank or other entity located in the United States and having appropriate facilities therefor, if such Certificateholder provides
the Certificate Administrator with wiring instructions no less than five Business Days prior to the related Record Date, or otherwise
(b) by check mailed to such Certificateholder. The final distribution on each Certificate shall be made in like manner, but only
upon presentment and surrender of such Certificate at the office of the Certificate Administrator or its agent (which may be the
Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice to Certificateholders of such
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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox

 

    	A-14-4

    	 

    

 

Accounts
and all proceeds of the Mortgage Loans deposited in the Collection Account, each 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 on behalf of the Trust in any environmental indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s
rights under the Loan Purchase Agreements to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and
Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 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
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 

 

    	A-14-5

    	 

    

 

	 	 	the related Distribution Date and (B) the change would not
adversely affect in any material respect the interests of any Certificateholder or Serviced Companion Loan Holder, 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 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

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 or, if applicable, any Serviced Companion Loan Holder, (B) to restrict (or to remove any existing restrictions

consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

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 

 

    	A-14-7

    	 

    

 

	 	 	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 any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of

 

    	A-14-8

    	 

    

 

the
Controlling Class Representative, each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing
within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class X-D Certificates. The Trust Fund, described more
fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial, multifamily and manufactured
housing community properties and held in trust by the Trustee and serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A, Class
X-B, Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class E, Class F, Class G, Class NR and Class R 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-D Certificates for such
Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

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

 

    	A-15-4

    	 

    

 

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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such 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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case

 

    	A-15-5

    	 

    

 

of
each Whole Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v)
the Master Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii)
the Trustee’s rights on behalf of the Trust 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 each case on behalf of the Trust,
in the Escrow Accounts and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each 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 on behalf of the Trust in any environmental indemnity agreements relating to the
Mortgaged Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee
pursuant to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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

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

will not adversely affect in any material respect the interests of any Certificateholder or, if applicable, any Serviced Companion
Loan Holder;

the consent of the Controlling Class Representative; (ii) 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; (iii) change in any

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 Certificate Administrator and the Trustee with the consent of the Holders

by the amendment for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of

that no such amendment shall:

 

    	A-15-8

    	 

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and

pursuant to the Pooling and Servicing Agreement;

 

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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.

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

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 purchasing
Master Servicer or the Special Servicer, as applicable, in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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

the voluntary exchange by the Remaining Certificateholder of its Certificates for all the Mortgage Loans and REO Properties (or

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 thereby continue beyond the expiration of twenty-one years from the death

Class C, Class D, Class X-D, Class F, Class G, Class NR and Class R Certificates (together with the Class E Certificates,
the “Certificates”; the Holders of Certificates issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class E Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder

 

    	A-16-3

    	 

    

 

at
a bank or other entity located in the United States and having appropriate facilities therefor, if such Certificateholder provides
the Certificate Administrator with wiring instructions no less than five Business Days prior to the related Record Date, or otherwise
(b) by check mailed to such Certificateholder. The final distribution on each Certificate shall be made in like manner, but only
upon presentment and surrender of such Certificate at the office of the Certificate Administrator or its agent (which may be the
Paying Agent or the Certificate Registrar acting as such agent) that is specified in the notice to Certificateholders of such
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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox

 

    	A-16-4

    	 

    

 

Accounts
and all proceeds of the Mortgage Loans deposited in the Collection Account, each 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 on behalf of the Trust in any environmental indemnity agreements relating to the Mortgaged Properties; (x) the Depositor’s
rights under the Loan Purchase Agreements to the extent assigned to the Trustee pursuant to Section 2.01 of the Pooling and
Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 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
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement or to correct
any error;

The Holders of the
Controlling Class representing greater than 50% of the Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in
property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum
of (A) the aggregate Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the
Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion
of each REO Property, if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B)
shall be obtained by the Special Servicer) and (C) 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
made by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of

 

    	A-16-8

    	 

    

 

the
Controlling Class Representative, each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing
within 30 days following the Early Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,
the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class F 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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A,
Class X-B, Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class
G, Class NR and Class R Certificates (together with the Class F Certificates, the “Certificates”; the Holders
of Certificates issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class F Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

    	A-17-5

    	 

    

 

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 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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such 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. 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

 

    	A-17-6

as applicable, any Companion Loan Holder:

 

    	A-17-7

    	 

    

 

		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement or to correct
any error;

Proceeds Reserve Account, any 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 or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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,

 

    	A-17-8

    	 

    

 

	 	 	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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) 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; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase

any 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, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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-17-9

    	 

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

		(vi)	adversely affect any Companion Loan Holder in its capacity as such without its consent;

of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the Companion Loan Holders) any time on or

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 made by such party, 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 purchasing
Master Servicer or the Special Servicer, as applicable, in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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

and Servicing Agreement.

 

The respective obligations
and responsibilities of the Master Servicer, the Special Servicer, the Depositor, the Operating Advisor, 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 to Certificateholders as set forth in the Pooling and Servicing

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class G 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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A,
Class X-B, Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class
NR and Class R Certificates (together with the Class G Certificates, the “Certificates”; the Holders of Certificates
issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class G Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

    	A-18-5

    	 

    

 

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 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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such 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. 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

 

    	A-18-6

    	 

    

 

or
collections in respect of the Mortgage Loans due after the Cut Off Date (or with respect to a Qualified Substitute Mortgage Loan,
the Due Date in the month of substitution); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of
the Trust’s interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the
case of each Whole Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property);
(v) the Master Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii)
the Trustee’s rights on behalf of the Trust 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 each case on behalf of the Trust,
in the Escrow Accounts and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each 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 on behalf of the Trust in any environmental indemnity agreements relating to the
Mortgaged Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee
pursuant to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or,
as applicable, any Companion Loan Holder:

 

    	A-18-7

    	 

    

 

		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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,

 

    	A-18-8

    	 

    

 

	 	 	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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) 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; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase
Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely affect
any 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, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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-18-9

    	 

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

 

		(iv)	change the definition of “Servicing Standard” without either (1) consent of 100% of
the holders of the Certificates or (2) 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 any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included

 

    	A-18-10

    	 

    

 

in
the Trust Fund, and all property or interests in property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase
price, payable in cash, equal to (i) the sum of (A) the aggregate Purchase Price (excluding the amount described in clause (e)
of the definition of Purchase Price) of all the Mortgage Loans (exclusive of REO Mortgage Loans) included in the Trust Fund, (B)
the Appraised Value of the Trust’s portion of each REO Property, if any, included in the Trust Fund, as determined by the
Special Servicer (such Appraisals in clause (i)(B) shall be obtained by the Special Servicer) and (C) 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 made by such party, 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 purchasing
Master Servicer or the Special Servicer, as applicable, in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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 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 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) shall terminate immediately following the earlier to occur of (i) the purchase by the Holders of the Controlling Class,

(or interests therein) then included in the Trust Fund pursuant to Section 9.01(c) of the Pooling and Servicing Agreement, (ii)
the voluntary 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

 

    	A-18-11

    	 

    

 

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 thereby continue beyond the expiration of twenty-one years from the death

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 NR 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 serviced by the Master Servicer. The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing Agreement (as defined below). The Holder of this
Certificate, by virtue of the acceptance hereof, assents to the terms, provisions and conditions of the Pooling and Servicing Agreement
and is bound thereby. In the event that there is any conflict between any provision of this Certificate and any provision of the
Pooling and Servicing Agreement, such provision of this Certificate shall be superseded to the extent of such inconsistency. Also
issued under the Pooling and Servicing Agreement are the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB, Class X-A,
Class X-B, Class X-F, Class X-G, Class X-NR, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F,
Class G and Class R Certificates (together with the Class NR Certificates, the “Certificates”; the Holders of
Certificates issued under the Pooling and Servicing Agreement 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 November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

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

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
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 of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class NR Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement.

 

    	A-19-5

    	 

    

 

Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class NR 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 close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such 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. 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

 

    	A-19-6

    	 

    

 

or
collections in respect of the Mortgage Loans due after the Cut Off Date (or with respect to a Qualified Substitute Mortgage Loan,
the Due Date in the month of substitution); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of
the Trust’s interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the
case of each Whole Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property);
(v) the Master Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii)
the Trustee’s rights on behalf of the Trust 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 each case on behalf of the Trust,
in the Escrow Accounts and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each 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 on behalf of the Trust in any environmental indemnity agreements relating to the
Mortgaged Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee
pursuant to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 Certificate Administrator and the Trustee, without the consent of any of the Certificateholders or,
as applicable, any Companion Loan Holder:

 

    	A-19-7

    	 

    

 

		(i)	to cure any ambiguity to the extent that it does not adversely affect any holders of Certificates
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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,

 

    	A-19-8

    	 

    

 

	 	 	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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) 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; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase
Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely affect
any 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, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate 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-19-9

    	 

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

the holders of the Certificates or (2) 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 any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the Special Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion
Loan Holder provided for in the related Co-Lender Agreement) then included

 

    	A-19-10

    	 

    

 

in
the Trust Fund, and all property or interests in property acquired by the Trust Fund in respect of any Mortgage Loan, at a purchase

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 made by such party, 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 purchasing
Master Servicer or the Special Servicer, as applicable, in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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 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 to Certificateholders as set forth in the Pooling and Servicing

the voluntary 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 thereby continue beyond the expiration of twenty-one years from the death

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 Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of November 1, 2015 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association, as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, and Midland Loan Services, a Division of
PNC Bank, National Association, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have
the meanings assigned thereto in the Pooling and Servicing Agreement.

 

This Certificate represents
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.

 

Pursuant to the terms
of the Pooling and Servicing Agreement, the Certificate Administrator will distribute (other than the final distribution on any
Certificate), on the 4th Business Day following the determination date of each month, commencing in December 2015 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of the aggregate amount, if any, allocable to the Class R Certificates for such Distribution Date, all as more fully described
in the Pooling and Servicing Agreement.

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last day
of the month immediately preceding the month in which such Distribution Date occurs, or if such day is not a Business Day, the
immediately preceding Business Day. Distributions are required to be made (a) by wire transfer of immediately available funds to
the account of such Certificateholder at a bank or other entity located in the United States and having appropriate facilities
therefor, if such Certificateholder provides the Certificate Administrator with wiring instructions no less than five Business
Days prior to the related Record Date, or otherwise (b) by check mailed to such Certificateholder. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and surrender of such Certificate at the office of the Certificate
Administrator or its agent (which may be the Paying Agent or the Certificate Registrar acting as such agent) that is specified
in the notice to Certificateholders of such 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

 

    	A-20-4

    	 

    

 

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. 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); (iii) any REO Property (but in the case of each Whole Loan, only to the extent of the Trust’s
interest in the related REO Property); (iv) all revenues received in respect of any REO Property (but in the case of each Whole
Loan, only to the extent of the Trust’s interest in the revenues received in respect of such REO Property); (v) the Master
Servicer’s and the Trustee’s rights, in each case on behalf of the Trust, 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 on behalf of the Trust in any Assignment of Leases and any security agreements; (vii) the Trustee’s
rights on behalf of the Trust 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 each case on behalf of the Trust, in the Escrow Accounts
and Lockbox Accounts and all proceeds of the Mortgage Loans deposited in the Collection Account, each 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 on behalf of the Trust in any environmental indemnity agreements relating to the Mortgaged
Properties; (x) the Depositor’s rights under the Loan Purchase Agreements to the extent assigned to the Trustee pursuant
to Section 2.01 of the Pooling and Servicing Agreement and (xi)  the Lower-Tier Regular Interests.

 

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

 

    	A-20-5

    	 

    

 

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 the Master Servicer, the Special Servicer, the Operating
Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing
Agreement and for all other purposes whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Trustee, the Certificate Administrator or the Certificate Registrar 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 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
or any Serviced Companion Loan Holder;

 

		(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 the Prospectus Supplement 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, any 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 or Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion Loan Holder, (B) to restrict (or to remove any existing restrictions
with respect to) the transfer of the Class R Certificates, provided that the Depositor has 

 

    	A-20-6

    	 

    

 

	 	 	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 or (C) to
the extent necessary to comply with the Investment Company Act, the Exchange Act, Regulation AB, and/or any related regulatory
actions and/or interpretations;

 

		(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 or, if applicable any Serviced Companion Loan Holder, 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 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 or, if applicable, any Serviced Companion
Loan Holder;

 

provided that
no amendment pursuant to any of clauses (i)-(vii) above may be made that would (i) 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; (ii) 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; (iii) change in any
manner the obligations or rights of any Mortgage Loan Seller under the Pooling and Servicing Agreement or the applicable Loan Purchase
Agreement without the consent of the affected Mortgage Loan Seller; (iv) 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 (v) adversely affect
any 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, Special Servicer or Trustee is requesting an amendment
for the benefit of the Certificateholders, then 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 Certificate Administrator and the Trustee with the consent of the Holders
of Certificates representing not less than 66-2/3% of the aggregate Percentage

 

    	A-20-7

    	 

    

 

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 Mortgage Loans
(or Serviced Whole Loans, if applicable) which are required to be distributed on a Certificate of any Class without the consent
of the Holder of that Certificate, or that are required to be distributed to any holder of a Serviced Companion Loan without the
consent of that holder;

 

		(ii)	reduce the aforesaid percentage of Certificates of any Class the Holders of which are required
to consent to the amendment or remove the requirement to obtain the consent of any Serviced Companion Loan Holder without the consent
of the Holders of all Certificates of that Class then-outstanding or the consent of each Serviced Companion Loan Holder, as applicable;

 

		(iii)	change in any manner the obligations or rights of any Mortgage Loan Seller under the Pooling and
Servicing Agreement or a Loan Purchase Agreement without the consent of the affected Mortgage Loan Seller;

 

		(iv)	change the definition of “Servicing Standard” without either (1) consent of 100% of
the holders of the Certificates or (2) 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 any Companion Loan Holder in its capacity as such without its consent;

 

		(vii)	adversely affect the Controlling Class Representative without the consent of 100% of the Controlling
Class Certificateholders; 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 Percentage Interest of the Controlling Class may effect an early termination
of the Trust Fund, upon not less than 30 days’ prior notice given to the Depositor, the Trustee, the Certificate Administrator,
the

 

    	A-20-8

    	 

    

 

Special
Servicer and Master Servicer (whereupon the Master Servicer shall notify the 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 Whole Loans, subject to certain rights of the related Companion Loan Holder
provided for in the related Co-Lender Agreement) then included in the Trust Fund, and all property or interests in property acquired
by the Trust Fund in respect of any Mortgage Loan, at a purchase price, payable in cash, equal to (i) the sum of (A) the aggregate
Purchase Price (excluding the amount described in clause (e) of the definition of Purchase Price) of all the Mortgage Loans (exclusive
of REO Mortgage Loans) included in the Trust Fund, (B) the Appraised Value of the Trust’s portion of each REO Property,
if any, included in the Trust Fund, as determined by the Special Servicer (such Appraisals in clause (i)(B) shall be obtained
by the Special Servicer) and (C) 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 made
by such party, 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 purchasing Master Servicer or the Special Servicer, as applicable,
in connection with such purchase).

 

The Holders of the
Controlling Class representing greater than 50% of the Certificate Principal 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 neither
such Holders nor the Special Servicer nor the Master Servicer does, any Holder of a Class R Certificate representing greater than
a 50% Percentage Interest in such Class, may also) effect such termination as provided in the prior paragraph if such party first
notifies the Controlling Class Representative and each Certifying Certificateholder, or, in the case of a termination by the Holder
of a Class R Certificate, notifies the Certificate Administrator (who shall notify each of the Controlling Class Representative,
each Certifying Certificateholder and the Master Servicer) of its intention to do so in writing within 30 days following the Early
Termination Notice 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 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 to Certificateholders as set forth in the Pooling and Servicing

by the Holders of the Controlling Class, the Special Servicer, the Master Servicer or the 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 voluntary 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 thereby 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.

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 Certificates for which an election is to be made under Section 860D of the
Internal Revenue Code of 1986 (the “Code”).

 

3.    The Purchaser
is not a “Disqualified Organization” (as defined below), and that the Purchaser is not acquiring the Class R
Certificates for the account of, or as agent or nominee of, or with a view to the transfer of direct or indirect record or beneficial
ownership thereof, to a Disqualified Organization. For the purposes hereof, a Disqualified Organization is any of the

 

    	Exhibit L-1-1

    	 

    

 

following:
(a) 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), (b) a foreign government, International Organization or agency or instrumentality of either of the
foregoing, (c) 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), (d) rural electric
and telephone cooperatives described in Code Section 1381(a)(2) or (e) 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.

 

8.     Check the applicable
paragraph:

 

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

 

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

 

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

 

    	Exhibit L-1-2

    	 

    

 

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

 

For purposes of this
calculation, (i) the Purchaser is assumed to pay tax at the highest rate currently specified in Section 11(b) of the
Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in Section 11(b)
of the Code if the Purchaser has been subject to the alternative minimum tax under Section 55 of the Code in the preceding
two years and will compute its taxable income in the current taxable year using the alternative minimum tax rate) and (ii) present
values are computed using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d) of the Code for
the month of the transfer and the compounding period used by the Purchaser.

 

☐    The transfer
of the Class R Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

 

(i)    the Purchaser
is an “eligible corporation”, as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to which income
from the Class R Certificate will only be taxed in the United States;

 

(ii)   at the time
of the transfer, and at the close of the Purchaser’s two fiscal years preceding the year of the transfer, the Purchaser had
gross assets for financial reporting purposes (excluding any obligation of a Person related to the Purchaser within the meaning
of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;

 

(iii)  the Purchaser
will transfer the Class R Certificate only to another “eligible corporation”, as defined in Treasury Regulations
Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of Sections 1.860E-1(c)(4)(i), (ii) and (iii) and
Treasury Regulations Section 1.860E-1(c)(5); and

 

(iv)  the Purchaser
determined the consideration paid to it to acquire the Class R Certificate based on reasonable market assumptions (including,
but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax
rates and other factors specific to the Purchaser) that it has determined in good faith.

 

☐    None of the above.

 

9.     The Purchaser
historically has paid its debts as they have come due and intends to pay its debts as they come due in the future and the Purchaser
intends to pay taxes associated with holding the Class R Certificates as they become due.

 

10.   The Purchaser
understands that it may incur tax liabilities with respect to the Class R Certificate in excess of any cash flows generated
by such Certificate.

 

11.   The Purchaser
is aware that the Certificate Registrar will not register any transfer of a Class R Certificate by the Transferor unless the
Purchaser, or such Purchaser’s agent, delivers to the Certificate Registrar, among other things, an affidavit and agreement
in substantially the same form as this affidavit and agreement. The Purchaser expressly agrees that it will not consummate any
such transfer to any Person that does not provide an affidavit and agreement in

 

    	Exhibit L-1-3

    	 

    

 

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 to the designation of the Certificate Administrator as the agent of the Tax Matters Person of the Lower-Tier REMIC and Upper-Tier
REMIC pursuant to Section 4.04 of the Pooling and Servicing Agreement.

 

Capitalized terms
used but not defined herein have the meanings assigned thereto in the Pooling and Servicing Agreement.

This letter is delivered
to you in connection with the transfer by [______] (the “Transferor”) to [______] (the “Transferee”) of
Class R Certificates evidencing a [__]% Percentage Interest in such Class (the “Residual Certificates”).
The Certificates, including the Residual Certificates, were issued pursuant to the Pooling and Servicing Agreement, dated as of
November 1, 2015 (the “Pooling and Servicing Agreement”), by and among Credit Suisse First Boston Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator, Wilmington Trust, National Association,

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 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

Ladies and Gentlemen:

 

This letter is delivered
pursuant to Section 5.03 of the Pooling and Servicing Agreement, dated as of November 1, 2015 (the “Pooling and Servicing
Agreement”), entered into by Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Pentalpha Surveillance
LLC, as Operating Advisor, Wells Fargo Bank, National Association, as Master Servicer, Midland Loan Services, a Division of PNC
Bank, National Association, as Special Servicer, Wells Fargo Bank, National Association, as Certificate Administrator, and Wilmington
Trust, National Association, as Trustee, on behalf of the holders of Commercial Mortgage Pass Through Certificates, Series 2015-C4
(the “Certificates”) in connection with the transfer by [             ]
(the “Seller”) to the undersigned (the “Purchaser”) of $_____ aggregate [Certificate Principal
Balance][Notional Amount] of Class [ ] Certificates [representing a [  ]% Percentage Interest in the related Class],
in certificated fully registered form (such registered interest, the “Certificate”). Terms used but not defined
herein shall have the meanings ascribed thereto in the Pooling and Servicing Agreement.

 

In connection with
such transfer, the undersigned hereby represents and warrants to you as follows:

 

[For Institutional
Accredited Investors only]1.The Purchaser is an institutional “accredited investor” (an “Institutional
Accredited Investor”), i.e., an entity meeting the requirements of Rule 501 (a)(1), (2), (3) or (7) of Regulation D under
the Securities Act of 1933, as amended (the “Securities Act”), or an entity in which all of the equity owners
come within Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act, and has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and risks of the investment in the Certificate, and the
Purchaser and any accounts for which the Purchaser is acting are each able to bear the economic risk of our or its investment.
The Purchaser is acquiring the Certificate for its own account or for one or more accounts (each

 

    	Exhibit L-4-1

    	 

    

 

of which is an Institutional Accredited
Investor), as to each of which the Purchaser exercises sole investment discretion. The Purchaser hereby undertakes to reimburse
the Trust for any costs incurred by it in connection with this transfer.

 

[For Qualified Institutional
Buyers only]1.The Purchaser is a “qualified institutional buyer” within the meaning of Rule 144A (“Rule
144A”) promulgated under the Securities Act of 1933, as amended (the “Securities Act”). The Purchaser
is aware that the transfer is being made in reliance on Rule 144A, and the Purchaser has had the opportunity to obtain the information
required to be provided pursuant to paragraph (d)(4)(i) of Rule 144A.

 

2.     The Purchaser’s
intention is to acquire the Certificate (a) for investment for the Purchaser’s own account or (b) for resale to (i) “qualified
institutional buyers” in transactions complying with Rule 144A, or (ii) Institutional Accredited Investors under the Securities
Act, pursuant to any other exemption from the registration requirements of the Securities Act, subject in the case of this clause
(ii) to (a) the receipt by the Certificate Registrar of a letter substantially in the form hereof, (b) the receipt by the
Certificate Registrar of an opinion of counsel acceptable to the Certificate Registrar that such reoffer, resale, pledge or transfer
is in compliance with the Securities Act, (c) the receipt by the Certificate Registrar of such other evidence acceptable to
the Certificate Registrar that such reoffer, resale, pledge or transfer is in compliance with the Securities Act and other applicable
laws (including applicable state and foreign securities laws), and (d) a written undertaking to reimburse the Trust for any
costs incurred by it in connection with the proposed transfer. It understands that the Certificate (and any subsequent Non-Book
Entry Certificate) has not been registered under the Securities Act, by reason of a specified exemption from the registration provisions
of the Securities Act which depends upon, among other things, the bona fide nature of the Purchaser’s investment intent (or
intent to resell to only certain investors in certain exempted transactions) as expressed herein.

 

3.    The Purchaser
acknowledges that the 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 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 November 23, 2015, relating to the 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 Certificate, except in compliance with Section 5.03 of the Pooling and Servicing
Agreement.

 

7.    Check one of
the following:

 

    	Exhibit L-4-2

    	 

    

 

☐          The
Purchaser is a “U.S. Tax Person” and it has attached hereto an Internal Revenue Service (“IRS”) Form W-9

☐          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 Certificate(s).
The Purchaser has attached hereto (i) a duly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or successor form),
which identifies such Purchaser as the beneficial owner of the 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 Certificate(s) and state that interest
and original issue discount on the 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 updated IRS Forms W-8BEN, IRS Forms W-8BEN-E, IRS Forms W-8IMY
or IRS Forms 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.

income tax purposes, an estate whose income is subject to United States federal income tax regardless of its source, or a trust
if a court within the United States is able to exercise primary supervision over the administration of such trust, and one or more

Treasury Regulations, certain trusts in existence on August 20, 1996 that have elected to be treated as U.S. Tax Persons).

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

 

You will treat the Confidential Information

or documents, deposition or similar process relating to any legal proceeding, investigation, hearing or otherwise) to disclose
any Confidential Information, you agree to provide the relevant Furnishing Entity with notice as soon as practicable (except in
the case of regulatory or other governmental inquiry, examination or investigation, and otherwise to the extent practical and permitted

order or reasonable assurance as to confidential treatment. If a Furnishing Entity succeeds in obtaining a protective order or
other remedy, you agree to comply with its terms with respect to the disclosure of the Confidential Information, at the sole expense
of such Furnishing Entity. If a protective order or other remedy is not obtained or if the relevant Furnishing Entity waives compliance
with the provisions of this Confidentiality Agreement in writing, you agree to furnish only such information as you are legally
required to disclose, at the sole expense of the relevant Furnishing Entity.

designed to ensure legal or regulatory compliance) and (b) the NRSRO may retain any portion of the Evaluation Material that may
be found in backup tapes or other archive or electronic media or other documents prepared by the NRSRO and any Evaluation Material

this Confidentiality Agreement and the NRSRO will remain bound by the terms of this Confidentiality Agreement.

You agree promptly to advise each relevant Furnishing Entity
in writing of any misappropriation or unauthorized disclosure or use by any person of the Confidential Information which may come

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

not to disclose such information, in any manner whatsoever, in whole or in part, to any other Person other than such other Persons’

		Re:	____________ Commercial Mortgage Pass-Through Certificates, Series 2015-C4 Mortgage Loan (the “Mortgage
Loan”) heretofore secured by real property known as ____________.

 

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

 

    	Exhibit DD-1

    	 

    

 

CONSISTENT WITH THE SERVICING STANDARD
SPECIFIED IN THE POOLING 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 Mortgage
Loan or the defeasance transaction:

 

1.            The Mortgagor has
consummated a defeasance of the Mortgage Loan of the type checked below:**

 

____ a full defeasance
of the entire outstanding principal balance ($____________) of the Mortgage Loan; or

 

____ a partial
defeasance of a portion ($____________) of the Mortgage Loan that represents ___% of the entire principal balance of the Mortgage
Loan ($____________).

 

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 and B were defeased simultaneously in their entirety; or

 

____ Promissory
Note B was paid off in full.]

 

5.            To the knowledge
of the Master Servicer any other debt related to the 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 (“TLGP”). Based upon a written report from an independent certified accountant,
such

 

    	Exhibit DD-2

    	 

    

 

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 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 Paying Agent’s Monthly Certificateholder Report 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 defined
in S&P’s criteria). The securities intermediary may reinvest proceeds of the defeasance

 

    	Exhibit DD-3

    	 

    

 

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 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 Scheduled
Payments including the payment in full of the Mortgage Loan (or the allocated portion thereof in connection with a partial defeasance)
on its Maturity Date (or, in the case of an ARD Loan, on its Anticipated Repayment Date), (ii) 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 Scheduled 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 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 the Trust to fail to
qualify as a REMIC for purpose of the Internal Revenue 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 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.          The outstanding
principal balance of the Mortgage Loan immediately before the defeasance was less than $35,000,000 and less than 5% of the aggregate
certificate balance of the Certificates as of the date of the Current Report. The Mortgage Loan is not one of the ten (10) largest
loans in the Pool as of the date of the Current Report.

in connection with the defeasance will be provided to you upon request.
