 2. Registration Under the Securities Act. 

(a) Except as set forth in Section 2(b) below, the Issuer agrees to use its best efforts to file or cause to be filed
under the Securities Act, as soon as practicable, but no later than on or 

  
 4 

 
before September 30, 2017 (in respect of the 2027 Notes) and September 30, 2018 (in respect of the 2047 Bonds), a registration statement relating to offers to exchange (such
registration statement, the “Exchange Offer Registration Statement”, and such offers, the “Exchange Offers”) any and all of the 2027 Notes and the 2047 Bonds for a like aggregate principal amount of debt securities issued by the
Issuer and guaranteed by the Guarantors, which debt securities and guaranties are substantially identical to the Securities and the related Guaranties, respectively (and are entitled to the benefits of a trust indenture which is substantially
identical to the Indenture or is the Indenture and which has been qualified under the Trust Indenture Act), except that they have been registered pursuant to an effective registration statement under the Securities Act, and do not contain provisions
for the additional interest contemplated in Section 2(c) below (such new debt securities hereinafter called the “2027 Exchange Notes” and the “2047 Exchange Notes”, respectively, and, together, the “Exchange
Securities”). The Exchange Securities will be fully fungible with, in respect of the 2027 Notes, the existing 6.500% Notes due 2027 (CUSIP Nos.: 71656L BQ3 and 71656M BQ1) originally issued by the Issuer on December 13, 2016, and, in
respect of the 2047 Bonds, the existing 6.750% Bonds due 2047 (CUSIP Nos.: 71656L BM2 and 71656M BM0) originally issued by the Issuer on September 21, 2016 and on October 3, 2016. The Issuer agrees to use its best efforts to cause the
Exchange Offer Registration Statement to become effective by the Commission under the Securities Act as soon as practicable, but no later than March 1, 2018 (in respect of the 2027 Notes) and March 1, 2019 (in respect of the 2047 Bonds).
The Exchange Offers will be registered under the Securities Act on the appropriate form and will comply with all applicable rules and regulations under the Exchange Act. The Issuer further agrees to use its best efforts to commence and complete the
Exchange Offers promptly, but no later than April 5, 2018 (in respect of the 2027 Notes) and April 5, 2019 (in respect of the 2047 Bonds), hold the Exchange Offers open for at least 30 days and issue and deliver Exchange Securities in
exchange for all Registrable Securities that have been properly tendered and not withdrawn on or prior to the expiration of the Exchange Offers. Each holder of Registrable Securities who wishes to exchange such Registrable Securities for Exchange
Securities in, and in accordance with the terms of, the Exchange Offers will be required to make certain customary representations in connection therewith, including representations that such holder is not a Restricted Holder. Upon the effectiveness
of the Exchange Offer Registration Statement, the Issuer shall promptly commence the Exchange Offers, it being the objective of such Exchange Offers that each holder (other than a Restricted Holder) electing to participate in the Exchange Offers
will receive Exchange Securities that are, upon receipt, transferable by each such holder without restriction under the Securities Act and the Exchange Act and without material restrictions under the blue sky or securities laws of a substantial
majority of the states of the United States of America. The Exchange Offers shall be deemed to have been completed upon the earlier to occur of (i) the Issuer having exchanged the Exchange Securities for all outstanding Registrable Securities
pursuant to the Exchange Offers and (ii) the Issuer having exchanged, pursuant to the Exchange Offers, Exchange Securities for all Registrable Securities that have been properly tendered and not withdrawn before the expiration of the Exchange
Offers, which shall be on a date that is at least 30 days following the commencement of the Exchange Offers. The Issuer agrees (x) to include in the Exchange Offer Registration Statement a prospectus for use in any resales by any holder of
Exchange Securities that is a broker-dealer and (y) to keep such Exchange Offer Registration Statement effective for a period (the “Resale Period”) beginning when Exchange Securities are first issued in the Exchange Offers and ending
upon the earlier of the expiration of the 180th day after the Exchange Offers have been completed or such time as such broker-dealers no longer own any Registrable Securities. With respect to such Exchange Offer Registration Statement, such
holders shall have the benefit of the rights of indemnification and contribution set forth in Sections 6 (a), (c), (d) and (e) hereof. 

  
 5 

 (b) If (i) on or prior to the time the Exchange Offers are completed,
existing Commission interpretations are changed such that the debt securities or the related guaranties received by holders other than Restricted Holders in the Exchange Offers for Registrable Securities are not or would not be, upon receipt,
transferable by each such holder without restriction under the Securities Act, (ii) the Exchange Offers have not been completed on or before April 5, 2018 (in respect of the 2027 Notes) and April 5, 2019 (in respect of the 2047 Bonds)
or (iii) any holder notifies the Issuer prior to 20 days after the consummation of the Exchange Offers that (A) based on the advice of counsel, due to a change in law or Commission policy it may not resell the Exchange Securities
acquired by it in the Exchange Offers to the public without delivering a prospectus and the prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such holder or (B) it is a
purchaser and owns Registrable Securities acquired directly from the Issuer or an affiliate of the Issuer or (C) on or prior to the consummation of the Exchange Offers existing laws, regulations and/or applicable Commission interpretations have
been changed such that the holders of at least a majority in aggregate principal amount of the Registrable Securities would not be able to resell the Exchange Securities acquired by them in, and in accordance with the terms of, the Exchange Offers
to the public without restriction under the Securities Act and without restriction under applicable blue sky or state securities laws, the Issuer shall, in lieu of (or, in the case of clause (iii), in addition to) conducting the Exchange Offers
contemplated by Section 2(a), use its best efforts to file or cause to be filed under the Securities Act as soon as practicable, but no later than the later of March 1, 2018 (in respect of the 2027 Notes) and March 1, 2019 (in respect
of the 2047 Bonds) or 30 days after the time such obligation to file arises (but in no event prior to August 1 or after September 30 of any calendar year), a “shelf” registration statement providing for the registration of,
and the sale on a continuous or delayed basis by the holders of, all of the Registrable Securities, pursuant to Rule 415 or any similar rule that may be adopted by the Commission (such filing, the “Shelf Registration” and such
registration statement, the “Shelf Registration Statement”). 
 The Issuer agrees to use its best efforts
(x) to cause the Shelf Registration Statement to become or be declared effective on or prior to 60 days after such filing was required to be made hereunder (but in no event prior to August 1 or after September 30 of any calendar
year) and (y) to keep such Shelf Registration Statement continuously effective for a period of one year (or, if shorter, the period after which Rule 144(d) generally becomes available to
non-affiliates of the Issuer) from the effective date of the Shelf Registration Statement (subject to extension pursuant to Sections 2(d) and 3(h)); provided, however, that if such
Shelf Registration Statement has been filed solely at the request of the Purchasers pursuant to clause (iii)(B) of this Section 2(b), the Issuer shall only be required to use its best efforts to keep such Shelf Registration Statement
continuously effective for a period of one year from the date of issuance of the Securities (subject to extension pursuant to Sections 2(d) and 3(h)) or until all of the Securities covered by the Shelf Registration Statement have been sold
pursuant to the Shelf Registration Statement or cease to be outstanding; provided further, however, that no holder shall be entitled to be named as a selling securityholder in the Shelf Registration Statement or to use the prospectus
forming a part thereof for resales of Registrable Securities unless such holder is an Electing Holder. The Issuer further agrees to supplement or make amendments to the Shelf Registration Statement, as and when required by the rules, regulations or
instructions applicable to the registration form used by the Issuer for such Shelf Registration Statement or by the Securities Act or rules and regulations thereunder for shelf registration, and the Issuer agrees to furnish to each Electing Holder
copies of any such supplement or amendment promptly after its being used or promptly following its filing with the Commission. 

  
 6 

 (c) If (i) the Exchange Offer Registration Statement (or a Shelf
Registration Statement in lieu thereof) is not filed on or before September 30, 2017 (in respect of the 2027 Notes) and September 30, 2018 (in respect of the 2047 Bonds), (ii) the Exchange Offer Registration Statement (or a Shelf
Registration Statement in lieu thereof) is not declared effective by the Commission on or before March 1, 2018 (in respect of the 2027 Notes) and March 1, 2019 (in respect of the 2047 Bonds), (iii) the Exchange Offers are not
consummated on or before April 5, 2018 (in respect of the 2027 Notes) and April 5, 2019 (in respect of the 2047 Bonds), (iv) a Shelf Registration Statement required to be filed is not filed on or before the date specified above for
such filing, (v) a Shelf Registration Statement otherwise required to be filed is not declared effective on or before the date specified above for effectiveness thereof or (vi) a Shelf Registration Statement is declared effective but
thereafter, subject to certain exceptions, ceases to be effective or usable (whether due to a stop order or otherwise) in connection with resales of Registrable Securities during the period specified in Section 2(b) above (each such event
referred to in clauses (i) through (vi) above, a “Registration Default”), then, in the case of a Registration Default referred to in clause (i), (ii) or (iii) above, the interest rate on all Registrable
Securities or, in the case of a Registration Default referred to in clause (iv), (v) or (vi) above, the interest rate on the Registrable Securities to which such Registration Default relates, will increase by 0.25% per annum with
respect to each 90-day period that passes until all such Registration Defaults have been cured, up to a maximum amount of 1.00% per annum (“Additional Interest”); provided, however,
that such Additional Interest will cease to accrue at the later of (i) the date on which the Securities become freely transferable pursuant to Rule 144 and (ii) the date on which the Barclays Capital U.S. Aggregate Bond Index is modified
to permit the inclusion of freely transferable securities that have not been registered under the Securities Act. Upon the cure of any such Registration Default, the interest rate borne by the Registrable Securities shall be reduced thereafter by
the full amount of any such increase or increases that resulted from such Registration Default. 
 The Issuer shall notify
the Trustee within three business days after each and every date on which an event occurs in respect of which Additional Interest is required to be paid (an “Event Date”). Additional Interest shall be paid by depositing with the
Trustee, in trust, for the benefit of the holders, on or before the applicable semiannual interest payment date, immediately available funds in sums sufficient to pay the Additional Interest then due. The Additional Interest due shall be payable on
each interest payment date to the record holder entitled to receive the interest payment to be paid on such date as set forth in the Indenture. Each obligation to pay Additional Interest shall be deemed to accrue from and including the day following
the applicable Event Date. 
 (d) Any Exchange Offer Registration Statement pursuant to Section 2(a) and any Shelf
Registration Statement pursuant to Section 2(b) will not be deemed to have become effective unless it has been declared effective by the Commission; provided, however, that, if after it has been declared effective, the offering of
Securities pursuant to a Shelf Registration Statement is subject to any stop order, injunction or other order or requirement of the Commission or any other governmental agency or court, such Registration Statement will be deemed not to have been
effective for such Securities during the period it was so subject, until the offering of such Securities pursuant to such Registration Statement may legally resume. 

In no event shall the Issuer be deemed to be in breach of its obligations under the second paragraph of Section 2(b) nor
shall a Registration Default described in Section 2(c)(vi) be deemed to have occurred (i) as a result of any action required by applicable law which renders the Issuer unable to comply with the Commission disclosure requirements or
(ii) if compliance with its 

  
 7 

 
obligations under this Agreement to maintain the effectiveness of, supplement or amend any Registration Statement, upon advice of U.S. counsel to the Issuer, would require additional disclosure
of material non-public information by the Issuer or its subsidiaries as to which, and so long as, the Issuer or its subsidiaries has a bona fide business purpose in preserving its confidentiality;
provided, however, that the maximum period of time during which the Issuer shall be entitled to postpone the effectiveness, supplementing or amending of any Registration Statement pursuant to clause (ii) of this paragraph
shall be 45 calendar days; provided, further, that (x) upon the exercise of its right under clause (ii) of this paragraph to postpone the effectiveness, supplementing or amending of any such Registration Statement,
the Issuer shall give the holders prompt written notice of such exercise and an approximation of the anticipated length of such postponement and (y) after the exercise of its right under clause (ii) of this paragraph to postpone the
effectiveness, supplementing or amending of any such Registration Statement, the Issuer shall not, within six months of the expiration of any such postponement, exercise again its right of postponement under clause (ii) of this paragraph.
The holders hereby acknowledge that any notice given by the Issuer pursuant to this paragraph may constitute material non-public information and that the United States securities laws prohibit any person who
has material non-public information about a company from purchasing or selling securities of the company or from communicating such information to any other person under circumstances in which it is reasonably
foreseeable that such person is likely to purchase or sell such securities. 
 (e) The Issuer shall take all actions
necessary or advisable to cause the Guaranties to be registered under the registration statement contemplated in Section 2(a) or 2(b) hereof, as applicable. 

(f) Any reference herein to a registration statement as of any time shall be deemed to include any document incorporated, or
deemed to be incorporated, therein by reference as of such time and any reference herein to any post-effective amendment to a registration statement as of any time shall be deemed to include any document incorporated, or deemed to be incorporated,
therein by reference as of such time. 
 3. Registration Procedures. 

If the Issuer files a registration statement pursuant to Section 2(a) or Section 2(b), the following provisions shall apply: 

(a) At or before the Effective Time of the Exchange Offers or the Shelf Registration, as the case may be, the Issuer shall
cause the Indenture to be qualified under the Trust Indenture Act. 
 (b) In the event that such qualification would require
the appointment of a new trustee under the Indenture, the Issuer shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture.

Section 2(a) (the “Exchange Registration”), if applicable, the Issuer shall, as soon as practicable (or as otherwise specified):

Securities;

jurisdiction or the initiation or threatening of any proceeding for such purpose, or (F) at any time during the Resale Period when a prospectus is required to be delivered under the Securities Act, that such Exchange Offer Registration
Statement, prospectus, prospectus amendment or supplement or post-effective prospectus amendment does not conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations
of the Commission thereunder or contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing;
and each such broker-dealer agrees to suspend use of such prospectus, prospectus amendment or supplement or post-effective amendment until the Issuer has amended or supplemented the prospectus to correct such misstatement or omission; 

(iv) in the event that the Issuer would be required, pursuant to Section 3(c)(iii)(F) above, to notify each broker-dealer
holding Exchange Securities that has identified itself to the Issuer as such, without delay prepare and furnish to each such holder a reasonable number of copies of a prospectus supplemented or amended so that,

jurisdiction wherein it would not otherwise be required to qualify but for the requirements of this Section 3(c)(vi), (2) consent to general service of process in any such jurisdiction or (3) make any changes to its certificate of

 (xv) in the event that any broker-dealer
registered under the Exchange Act shall underwrite any Registrable Securities or participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the
“Conduct Rules”) of the Financial Industry Regulatory Authority (“FINRA”, formerly the National Association of Securities Dealers, Inc.) or any successor thereto, as amended from time to time) thereof, whether as a holder of such
Registrable Securities or as an underwriter, a placement or sales agent or a broker or 

  
 14 

 
dealer in respect thereof, or otherwise, assist such broker-dealer in complying with the requirements of such Conduct Rules, including by (A) if such Conduct Rules shall so require, engaging
a “qualified independent underwriter” (as defined in such Conduct Rules) to participate in the preparation of the Shelf Registration Statement relating to such Registrable Securities, to exercise usual standards of due diligence in respect
thereto and, if any portion of the offering contemplated by such Shelf Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Registrable Securities, (B) indemnifying any
such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 6 hereof (or to such other customary extent as may be requested by such underwriter), and (C) providing such information to

(including, at the option of the Issuer, Rule 158 thereunder) (it being understood that the Issuer may satisfy its obligations under this clause through the filing of its annual report on Form 20-F
for the first full fiscal year after such effective date). 
 (e) In the event that the Issuer would be required, pursuant to
Section 3(d)(vi)(F) above, to notify the Electing Holders and the managing underwriters, if any, thereof, the Issuer shall without delay prepare and furnish to each of the Electing Holders and to each such underwriter, if any, a reasonable
number of copies of a prospectus supplemented or amended so that, as thereafter delivered to purchasers of Registrable Securities, such prospectus shall conform in all material respects to the applicable requirements of the Securities Act and the
Trust Indenture Act and the rules and regulations of the Commission thereunder and shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing. Each Electing Holder agrees that upon receipt of any notice from the Issuer pursuant to Section 3(d)(vi)(F) above, such Electing Holder shall forthwith discontinue the disposition of
Registrable Securities pursuant to the Shelf Registration Statement applicable to such Registrable Securities until such Electing Holder shall have received copies of such amended or supplemented prospectus, and if so directed by the Issuer, such
Electing Holder shall deliver to the Issuer (at the Issuer’s expense) all copies, other than permanent file copies, then in such Electing Holder’s possession of the prospectus covering such Registrable Securities at the time of receipt of
such notice. 
 (f) In the event of a Shelf Registration, in addition to the information required to be provided by each
Electing Holder in its Notice Questionnaire, the Issuer may require such Electing Holder to furnish to the Issuer such additional information regarding such Electing Holder and such Electing Holder’s intended method of distribution of
Registrable Securities as the Issuer may, after consulting with counsel, determine is required in order to comply with the Securities Act. Each such Electing Holder agrees to notify the Issuer as promptly as practicable of any inaccuracy or change
in information previously furnished by such Electing Holder to the Issuer or of the occurrence of any event in either case as a result of which any prospectus relating to such Shelf Registration contains or would contain an untrue statement of a
material fact regarding such Electing Holder or such Electing Holder’s intended method of disposition of such Registrable Securities or omits to state any material fact regarding such Electing Holder or such

  
 15 

 
Electing Holder’s intended method of disposition of such Registrable Securities required to be stated therein or necessary to make the statements therein not misleading in light of the
circumstances then existing, and promptly to furnish to the Issuer any additional information required to correct and update any previously furnished information or required so that such prospectus shall not contain, with respect to such Electing
Holder or the disposition of such Registrable Securities, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances
then existing. 
 (g) Until the expiration of one year after the Settlement Date, the Issuer will not, and will not
permit any of the Issuer’s direct and indirect subsidiaries or the Guarantors to, resell any of the Securities that have been reacquired by any of them except pursuant to an effective registration statement under the Securities Act. 

(h) In the case of a Shelf Registration Statement or the notification of the Issuer by broker-dealers seeking to sell Exchange
Securities and required to deliver prospectuses that will be utilizing the prospectus contained in the Exchange Offer Registration Statement, each holder agrees that, upon receipt of any notice from the Issuer of (i) the happening of any event
of the kind described in any of clauses (B) – (F) of Section 3(d)(vi) or (ii) the exercise of the Issuer’s right, under clause (ii) of the second paragraph of Section 2(d), to postpone the effectiveness,
supplementing or amending of any such Registration Statement, such holder will forthwith discontinue disposition of Securities pursuant to the applicable Registration Statement until such holder receives the copies of the supplemented or amended
prospectus contemplated by Section 3(c)(iv) or Section 3(e) or until such holder is advised in writing (the “Advice”) by the Issuer that the use of the applicable prospectus may be resumed, and, if so directed by the Issuer, such
holder will deliver to the Issuer (at the Issuer’s expense) all copies in such holder’s possession, other than permanent file copies, of the prospectus covering such Securities current at the time of receipt of such notice. If the Issuer
shall give any such notice to suspend the disposition of any Securities pursuant to a Registration Statement, the Issuer shall use its best efforts to file a supplement or an amendment to the Registration Statement and, in the case of an amendment,
have such amendment declared effective as soon as practicable and shall extend the period during which such Registration Statement shall be maintained effective pursuant to this Agreement by the number of days in the period from and including the
date of the giving of such notice to and including the date when the Issuer shall have made available to the holders (i) copies of the supplemented or amended prospectus necessary to resume such dispositions or (ii) the Advice. 

4. Registration Expenses.

sale of the Securities), up to U.S. $50,000; and (e) any fees associated with listing the Exchange Securities on the Luxembourg Stock Exchange and the consummation by the transactions contemplated by this Agreement in Luxembourg. To the extent
that any Registration Expenses are incurred, assumed or paid by any holder of Registrable Securities therefor or underwriter thereof, the Issuer shall reimburse such person for the full amount of the Registration Expenses so incurred, assumed or
paid promptly after receipt of a request therefor. Notwithstanding the foregoing, the holders of the Registrable Securities being registered shall pay all agency fees and commissions and underwriting discounts and commissions attributable to the
sale of such Registrable Securities and the fees and disbursements of any counsel or other advisors or experts retained by such holders (severally or jointly), other than the counsel and experts specifically referred to above. 

5. Representations and Warranties. 

The Issuer represents and warrants to, and agrees with, the Purchasers and each of the holders from time to time of Registrable Securities
that: 
 (a) The compliance by the Issuer with the provisions of this Agreement, and the consummation of the transactions
herein contemplated will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any material agreement or material instrument to which the Issuer or any of the Guarantors is a party or by which
the Issuer or any of the Guarantors is bound or to which any of the property or assets of the Issuer or any of the Guarantors is subject, nor will such action result in any violation of the provisions of the Ley de Petróleos Mexicanos
(the “Petróleos Mexicanos Law”) and related regulations or any other statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Issuer or any of the Guarantors or any of its or
their respective properties; 

  
 17 

 (b) This Agreement has been duly authorized, executed and delivered by the
Issuer. 
 6. Indemnification. 

(a) Indemnification by the Issuer. The Issuer will indemnify and hold harmless each of the holders of Registrable
Securities included in an Exchange Offer Registration Statement, each of the Electing Holders of Registrable Securities included in a Shelf Registration Statement and each person who participates as an underwriter in any offering or sale of such
Registrable Securities against any losses, claims, damages or liabilities, joint or several, to which such holder or underwriter may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Exchange Offer Registration Statement or Shelf Registration Statement, as the case may be (or any
amendment or supplement thereto), under which such Registrable Securities were registered under the Securities Act, including all exhibits therein and documents incorporated by reference thereto, or any preliminary or final prospectus contained
therein or furnished by the Issuer to any such holder, Electing Holder or underwriter, or any amendment or supplement thereto, or any free writing prospectus (as defined in Rule 405) prepared by or on behalf of the Issuer or used or referred to by
the Issuer in connection with the Exchange Offers or the Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading, and will reimburse such holder, such Electing Holder and such underwriter for any reasonable and duly documented legal or other expenses incurred by them in
connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Issuer shall not be liable to any such person in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, or preliminary, final or summary prospectus, or amendment or supplement thereto,
in reliance upon and in conformity with written information furnished to the Issuer by such person expressly for use therein. 

(b) Indemnification by the Holders and Underwriters. The Issuer may require, as a condition to including any Registrable
Securities in any registration statement filed pursuant to Section 2(b) hereof and to entering into any underwriting agreement with respect thereto, that the Issuer shall have received an undertaking reasonably satisfactory to it from the
Electing Holder of such Registrable Securities and from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and hold harmless the Issuer and all other holders of Registrable Securities, against
any losses, claims, damages or liabilities to which the Issuer or such other holders of Registrable Securities may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such registration statement, or any preliminary, final or summary prospectus contained therein or furnished by the Issuer to any
such Electing Holder or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon
and in conformity with written information furnished to the Issuer by such Electing Holder or underwriter expressly for use therein, and (ii) reimburse the Issuer for any reasonable and duly 

  
 18 

 
documented legal or other expenses incurred by the Issuer in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however,
that no such Electing Holder shall be required to undertake liability to any person under this Section 6(b) for any amounts in excess of the dollar amount of the proceeds to be received by such Electing Holder from the sale of such Electing
Holder’s Registrable Securities pursuant to such registration. 
 (c) Notices of Claims, Etc. Promptly
after receipt by an indemnified party under Section 6(a) or Section 6(b) above of written notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying
party pursuant to the indemnification provisions of or contemplated by this Section 6, notify such indemnifying party in writing of the commencement of such action; but the omission so to notify the indemnifying party shall not relieve it from
any liability which it may have to any indemnified party otherwise than under the indemnification provisions of or contemplated by Section 6(a) or Section (b) above. In case any such action shall be brought against any indemnified party
and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable and duly documented costs in a manner customary for the indemnified party of investigation. The indemnifying party shall not be liable for any settlement of any
proceeding effected without its written consent, which shall not be unreasonably withheld. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any
judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless
such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability
or a failure to act by or on behalf of any indemnified party. 
 (d) Contribution. If for any reason the
indemnification provisions contemplated by Section 6(a) or Section 6(b) are unavailable to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein
although applicable in accordance with their terms, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in
such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were determined by 

  
 19 

 
pro rata allocation (even if the holders or any underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in this Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above shall be deemed to include
any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), no holder shall be required to
contribute any amount in excess of the amount by which the dollar amount of the proceeds received by such holder from the sale of any Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount
of any damages which such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no underwriter shall be required to contribute any amount in excess of the amount by which
the total price at which the Registrable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The holders’ and any underwriters’ obligations in this Section 6(d) to contribute shall be several in proportion to the principal amount of Registrable Securities registered or underwritten, as the case
may be, by them and not joint. 
 (e) The obligations of the Issuer under this Section 6 shall be in addition to any
liability which the Issuer may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of each holder and underwriter and each person, if any, who controls any holder, agent or underwriter within
the meaning of the Securities Act, and the obligations of the holders and any agents or underwriters contemplated by this Section 6 shall be in addition to any liability which the respective holder, agent or underwriter may otherwise have and
shall extend, upon the same terms and conditions, to each officer and director of the Issuer (including any person who, with his consent, is named in any registration statement as about to become a director of the Issuer) and to each person, if any,
who controls the Issuer within the meaning of the Securities Act. 
 7. Underwritten Offerings. 

(a) Selection of Underwriters. If any of the Registrable Securities covered by the Shelf Registration are to be sold
pursuant to an underwritten offering, the managing underwriter or underwriters thereof shall be designated by Electing Holders holding at least a majority in aggregate principal amount of the Registrable Securities to be included in such offering,
provided, however, that such designated managing underwriter or underwriters is or are acceptable to the Issuer. 

(b) Participation by Holders. Each holder of Registrable Securities hereby agrees with each other such holder that no
such holder may participate in any underwritten offering hereunder unless such holder (i) agrees to sell such holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder
to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

Issuer shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted
by the Commission under the Securities Act) and the rules and regulations adopted by the Commission thereunder, and shall take such further action as any holder of Registrable Securities may reasonably request, all to the extent required from time
to time to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144, as such Rule may be amended from time to time, or any similar or
successor rule or regulation hereafter adopted by the Commission. Upon the request of any holder of Registrable Securities in connection with that holder’s sale pursuant to Rule 144, the Issuer shall deliver to such holder a written
statement as to whether it has complied with such requirements. 
 9. Miscellaneous. 

(a) No Inconsistent Agreements. The Issuer represents, warrants, covenants and agrees that it has not granted, and shall
not grant, registration rights with respect to Registrable Securities or any other securities which would be inconsistent with the rights granted to the holders of the Registrable Securities in this Agreement.

or any such holder may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt. 

(c) Parties in Interest. All the terms and provisions of this Agreement shall be binding upon, shall inure to the
benefit of and shall be enforceable by the parties hereto and the holders from time to time of the Registrable Securities and the respective successors and assigns of the parties hereto and such holders. In the event that any transferee of any
holder of Registrable Securities shall acquire Registrable Securities, in any manner, whether by gift, bequest, purchase, operation of law or otherwise, such transferee shall, without any further writing or action of any kind, be deemed a
beneficiary hereof for all purposes, and such Registrable Securities shall be held subject to all of the terms of this Agreement; and by taking and holding such Registrable Securities such transferee shall be entitled to receive the benefits of, and
be conclusively deemed to have agreed to be bound by, all of the applicable terms and provisions of this Agreement. If the Issuer shall so request, any such successor, assign or transferee shall agree in writing to acquire and hold the Registrable
Securities subject to all of the applicable terms hereof. 
 (d) Survival. The respective indemnities, agreements,
representations, warranties and each other provision set forth in this Agreement or made pursuant hereto shall remain in full force and effect regardless of any investigation (or statement as to the results thereof) made by or on behalf of any
holder of Registrable Securities, the Issuer, any director, officer or partner of such holder or the Issuer, any agent or underwriter or any director, officer or partner thereof, or any controlling person of any of the foregoing, and shall survive

controversy or dispute relating to or arising out of this Agreement, shall be governed by and construed in accordance with the laws of the State of New York except that the authorization and execution of this Agreement by the Issuer shall be
governed by the laws of the United Mexican States.

with respect to its subject matter. This Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a written instrument
duly executed by the Issuer and the holders of at least a majority in aggregate principal amount of the Registrable Securities at the time outstanding. Each holder of any Registrable Securities at the time or thereafter outstanding shall be bound by

Agreement, the Indenture, the Guaranty Agreement, the Securities, or any other liability or obligation of the Issuer and/or each of the Guarantors related to or arising from the transactions contemplated thereby in respect of itself or its property.

 (j) Agent for Service; Submission to Jurisdiction; Waiver of Immunities. The Issuer hereby appoints the Consul
General of Mexico in New York City (currently Ms. Sandra Fuentes-Berain) and its successors as its authorized agent (the “Authorized Agent”) upon which process may be served in any action by any Purchaser, or by any persons
controlling such Purchaser, arising out of or based upon this Agreement which each of the parties hereto hereby agrees that, in respect of any actions brought against it as a defendant may be instituted in the U.S. District Court for the Southern
District of New York and any appellate court or body thereto (collectively, the “Federal Courts”) referred to below. Each of the parties hereto irrevocably submits to the jurisdiction of the Federal Courts in respect of any action arising
out of or based upon this Agreement and irrevocably waives any objection which it may now or hereafter have to the laying of venue of any such action in any such court, and each such party further waives any right to which it may be entitled on
account of present or future residence or domicile. The appointment made by the Issuer shall be irrevocable as long as any of the Securities remain 

  
 22 

 
outstanding, unless and until a successor agent shall have been appointed the Issuer’s Authorized Agent and such successor agent shall have accepted such appointment. The Issuer will take
any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment or appointments in full force and effect as aforesaid. Service of process upon the Authorized Agent at 27 East
39th Street, New York, New York 10016, and written notice of such service mailed or delivered to the Issuer at the address set forth in Section 9(b) above shall be deemed, in every respect, effective service of process upon the Issuer. The
Issuer hereby waives irrevocably any immunity from jurisdiction to which it might otherwise be entitled (including, to the extent applicable, sovereign immunity, immunity to pre-judgment attachment,
post-judgment attachment and execution) in any such action in any federal court in The City of New York, or in any competent court in Mexico, subject to certain restrictions pursuant to applicable law, including (i) the adoption of the Law of
Petróleos Mexicanos, the Hydrocarbons Law and any other new law or regulation or (ii) any amendment to, or change in the interpretation or administration of, any existing law or regulation, in each case, pursuant to or in connection with
the Energy Reform Decree by any governmental authority in Mexico with oversight or authority over the Issuer or its subsidiaries.

 Reference is
hereby made to the Exchange and Registration Rights Agreement dated December 13, 2016 (the “Exchange and Registration Rights Agreement”) among Petróleos Mexicanos (the “Issuer”) and the Purchasers named therein. Pursuant
to the Exchange and Registration Rights Agreement, the Issuer intends to file with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form [    ] (the “Shelf

prospectus. 

 ELECTION 

The undersigned holder (the “Selling Securityholder”) of Registrable Securities hereby elects to include in the Shelf Registration Statement the
Registrable Securities beneficially owned by it and listed below in Item (3). The undersigned, by signing and returning this Notice and Questionnaire, agrees to be bound with respect to such Registrable Securities by the terms and conditions of

claims, damages or liabilities to which the Issuer or such other holders of Registrable Securities may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such registration statement, or any preliminary, final or summary prospectus contained therein or furnished by the Issuer to any such
holder or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Issuer by such holder expressly for use therein, and (ii) reimburse the Issuer for any reasonable and duly documented legal or other expenses incurred by the Issuer in connection with investigating or
defending any such action or claim as such expenses are incurred; provided, however, that no such holder shall be required to undertake liability to any person hereunder for any amounts in excess of the dollar amount of the
proceeds to be received by such holder from the sale of such holder’s Registrable Securities pursuant to such registration. 
 Upon any sale of

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

 

PRELIMINARY
STATEMENT:

 

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

 

In
addition, the parties intend that the portions of the issuing entity consisting of the Specific Grantor Trust Assets and the ARD
Grantor Trust Assets will be treated as a grantor trust (the “Grantor Trust”) for federal income tax purposes
under subpart E, part I of subchapter J of the Code. Each Class of Certificates other than the Class R Certificates will represent
undivided beneficial interests in the portion of the Grantor Trust consisting of the Specific Grantor Trust Assets with the corresponding
alphabetical or alphanumeric designation. As provided herein, the Certificate Administrator shall take all actions expressly required
hereunder to ensure that the portion of the Trust Fund consisting of the Grantor Trust maintains its status as a grantor trust
under federal income tax law and not be treated as part of the Trust REMICs.

 

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

 

LOWER-TIER
REMIC

 

The
Lower-Tier REMIC will hold the Mortgage Loans (exclusive of Excess Interest) and will issue the Class LA-1, Class LA-2, Class LA-3,
Class LA-4, Class LA-5, Class LA-SB, Class LA-S, Class LB, Class LC, Class LD, Class LE, Class LF and Class
LNR Uncertificated Interests (the “Lower-Tier Regular Interests”), which will evidence the “regular interests”
in the Lower-Tier REMIC created hereunder. The Lower-Tier REMIC will also issue the uncertificated Class LR Interest, which
is the sole Class of “residual interest” in the Lower-Tier REMIC for purposes of the REMIC Provisions and is represented
by the Class R Certificates.

 

    -1-

     

    

 

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

that, with respect to each Actual/360 Mortgage Loan, the Net Mortgage Rate for the one-month period (A) preceding the Due Dates
that occur in January and February in any year which is not a leap year or preceding the Due Date that occurs in February in any
year which is a leap year (in any event, unless the related Distribution Date is the final Distribution Date), will be determined
exclusive of any Withheld Amounts in respect of such Actual/360 Mortgage Loan, and (B) preceding the Due Date in March (or February,
if the related Distribution Date is the final Distribution Date), will be determined inclusive of the Withheld Amounts in respect

    -92-

     

    

 

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

 

“Nonrecoverable
P&I Advance”: Any P&I Advance previously made or proposed to be made in respect of a Mortgage Loan (including
any Non-Serviced Mortgage Loan) or REO Loan (excluding any portion of an REO Loan related to any other Companion Loan) which the
Master Servicer, in accordance with the Servicing Standard, or the Trustee, in its good faith business judgment, as applicable,
determines would not be ultimately recoverable, together with any accrued and unpaid interest thereon at the Reimbursement Rate,
from Late Collections or any other recovery on or in respect of such Mortgage Loan or REO Loan; provided, however,
that the Special Servicer may, at its option make a determination in accordance with the Servicing Standard, that any P&I
Advance previously made or proposed to be made is a Nonrecoverable P&I Advance and shall deliver to the Master Servicer (and
with respect to a Serviced Mortgage Loan, to any Other Servicer, and, with respect to a Non-Serviced Mortgage Loan, to the related
Non-Serviced Master Servicer and Non-Serviced Special Servicer), the Certificate Administrator, the Trustee, the Operating Advisor
and the 17g-5 Information Provider notice of such determination. Any such determination may be conclusively relied upon by, and
shall be binding upon, the Master Servicer and the Trustee, provided, however, that the Special Servicer shall not
have such obligation to make an affirmative determination that any P&I Advance is or would be recoverable and in the absence
of a determination by the Special Servicer that such P&I Advance is or would be a Nonrecoverable P&I Advance, such decision
shall remain with the Master Servicer or Trustee, as applicable. If the Special Servicer makes a determination that only a portion,
and not all, of any previously made or proposed P&I Advance is a Nonrecoverable P&I Advance, the Master Servicer and the
Trustee shall have the right to make its own subsequent determination that any remaining portion of any such previously made or
proposed P&I Advance is a Nonrecoverable P&I Advance. With respect to any Non-Serviced Whole Loan, if any Non-Serviced
Master Servicer or Non-Serviced Special Servicer, as applicable, in connection with a securitization of the related Non-Serviced
Companion Loan determines that a principal and interest advance with respect to the related Non-Serviced Companion Loan, if made,
would be a “nonrecoverable P&I advance”, such determination shall not be binding on the Master Servicer and the
Trustee as it relates to any proposed P&I Advance with respect to the related Non-Serviced Mortgage Loan. Similarly, with
respect to the related Non-Serviced Mortgage Loan, if the Master Servicer, the Special Servicer or the Trustee, as applicable,
determines that any P&I Advance with respect to a related Non-Serviced Mortgage Loan, if made, would be a Nonrecoverable P&I
Advance, such determination shall not be binding on the related Non-Serviced Master Servicer and related Non-Serviced Trustee
as it relates to any proposed P&I Advance with respect to the related Non-Serviced Companion Loan (unless the related Non-Serviced
PSA provides otherwise). In making such recoverability determination, the Master Servicer, the Special Servicer or the Trustee,
as applicable, will be entitled (a) to consider (among other things) (i) the obligations of the Mortgagor under the terms of the
related Mortgage Loan or Companion Loan as it may have been modified and (ii) the related Mortgaged Properties in their “as-is”
or then-current conditions and occupancies, as modified by such party’s assumptions (consistent with the Servicing Standard
in the case of the Master Servicer or the Special Servicer or in its good faith business judgment in the case of the Trustee,
solely in its capacity as Trustee) regarding the possibility and effects of future adverse changes with respect to such Mortgaged
Properties, (b) to estimate and consider (among other things) future expenses, (c) to estimate and consider

 

    -93-

     

    

 

(consistent
with the Servicing Standard in the case of the Master Servicer and the Special Servicer or in its good faith business judgment
in the case of the Trustee, solely in its capacity as Trustee) (among other things) the timing of recoveries, and (d) to give
due regard to the existence of any Nonrecoverable Advances which, at the time of such consideration, the recovery of which are
being deferred or delayed by the Master Servicer or the Trustee because there is insufficient principal available for such recovery,
in light of the fact that related proceeds are a source of recovery not only for the Advance under consideration but also a potential
source of recovery for such delayed or deferred Advance. In addition, any Person, in considering whether a P&I Advance is
a Nonrecoverable Advance, will be entitled to give due regard to the existence of any outstanding Nonrecoverable Advance or Workout-Delayed
Reimbursement Amount with respect to other Mortgage Loans, the reimbursement of which, at the time of such consideration, is being
deferred or delayed by the Master Servicer or the Trustee because there is insufficient principal available for such reimbursement,
in light of the fact that proceeds on the related Mortgage Loan are a source of reimbursement not only for the P&I Advance
under consideration, but also as a potential source of reimbursement of such Nonrecoverable Advance or Workout-Delayed Reimbursement
Amounts which are or may be being deferred or delayed. In addition, any such Person may update or change its recoverability determinations
at any time (but not reverse any other Person’s determination that an Advance is a Nonrecoverable Advance) and, consistent
with the Servicing Standard, in the case of the Master Servicer or in its good faith business judgment in the case of the Trustee
(solely in its capacity as Trustee), may obtain at the expense of the Trust any reasonably required analysis, Appraisals or market
value estimates or other information for making a recoverability determination. Absent bad faith, the Master Servicer’s,
the Special Servicer’s or the Trustee’s determination as to the recoverability of any P&I Advance shall be conclusive
and binding on the Certificateholders. The determination by the Master Servicer, the Special Servicer or the Trustee, as applicable,
that the Master Servicer or the Trustee, as applicable, has made a Nonrecoverable P&I Advance or that any proposed P&I
Advance, if made, would constitute a Nonrecoverable P&I Advance, or any updated or changed recoverability determination, shall
be evidenced by an Officer’s Certificate delivered by either the Special Servicer or the Master Servicer to the other and
to the Trustee, the Certificate Administrator and the Directing Certificateholder (but in the case of the Directing Certificateholder,
only prior to the occurrence and continuance of a Consultation Termination Event and only with respect to any Mortgage Loan other
than an Excluded Loan as to such party) (and, in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any Other
Servicer or Non-Serviced Master Servicer, as applicable), the Operating Advisor (but only in the case of the Special Servicer),
the Depositor, or by the Trustee to the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor (and, in the
case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced Master Servicer, as applicable)
and the Certificate Administrator. The Officer’s Certificate shall set forth such determination of nonrecoverability and
the considerations of the Master Servicer, the Special Servicer or the Trustee, as applicable, forming the basis of such determination
(which shall be accompanied by, to the extent available, income and expense statements, rent rolls, occupancy status, property
inspections and any other information used by the Master Servicer, the Special Servicer or the Trustee, as applicable, to make
such determination and shall include any existing Appraisal of the related Mortgage Loan, or the related Mortgaged Property).
The Trustee shall be entitled to conclusively rely on the Master Servicer’s or Special Servicer’s determination that
a P&I Advance is or would be nonrecoverable, and the Master Servicer shall be entitled to 

 

    -94-

     

    

 

conclusively
rely on the Special Servicer’s determination that a P&I Advance is or would be nonrecoverable, which determination shall
be binding on the Master Servicer and the Trustee. In the case of a cross-collateralized Mortgage Loan (if any), such recoverability
determination shall take into account the cross-collateralization of the related cross-collateralized Mortgage Loan.

 

“Nonrecoverable
Servicing Advance”: Any Servicing Advance previously made or proposed to be made in respect of a Mortgage Loan (other
than a Non-Serviced Mortgage Loan), Whole Loan or REO Property which the Master Servicer, the Special Servicer, in each case in
accordance with the Servicing Standard, or the Trustee, in its good faith business judgment, as applicable, determines would not
be ultimately recoverable, together with any accrued and unpaid interest thereon, at the Reimbursement Rate, from Late Collections
or any other recovery on or in respect of such Mortgage Loan, Whole Loan or REO Property. In making such recoverability determination,
such Person will be entitled (a) to consider (among other things) (i) the obligations of the Mortgagor under the terms of the
related Mortgage Loan or Companion Loan, as applicable, as it may have been modified and (ii) the related Mortgaged Properties
in their “as-is” or then-current conditions and occupancies, as modified by such party’s assumptions (consistent
with the Servicing Standard in the case of the Master Servicer or the Special Servicer or in its good faith business judgment
in the case of the Trustee, solely in its capacity as Trustee) regarding the possibility and effects of future adverse change
with respect to such Mortgaged Properties, (b) to estimate and consider (among other things) future expenses, (c) to estimate
and consider (consistent with the Servicing Standard in the case of the Master Servicer or the Special Servicer or in its good
faith business judgment in the case of the Trustee, solely in its capacity as Trustee) (among other things) the timing of recoveries
and (d) give due regard to the existence of any Nonrecoverable Advances that, at the time of such consideration, the recovery
of which are being deferred or delayed by the Master Servicer or the Trustee because there is insufficient principal available
for such reimbursement, in light of the fact that Related Proceeds are a source of recovery not only for the Advance under consideration
but also a potential source of recovery for such delayed or deferred Advance. In addition, any Person, in considering whether
a Servicing Advance is a Nonrecoverable Servicing Advance, will be entitled to give due regard to the existence of any Nonrecoverable
Advance or Workout-Delayed Reimbursement Amounts with respect to other Mortgage Loans, the reimbursement of which, at the time
of such consideration, is being deferred or delayed by the Master Servicer, in light of the fact that proceeds on the related
Mortgage Loan are a source of recovery not only for the Servicing Advance under consideration, but also as a potential source
of recovery of such Nonrecoverable Advance or Workout-Delayed Reimbursement Amounts which are or may be being deferred or delayed.
In addition, any such Person may update or change its recoverability determinations at any time (but not reverse any other Person’s
determination that an Advance is a Nonrecoverable Advance) and, consistent with the Servicing Standard, in the case of the Master
Servicer or in its good faith business judgment in the case of the Trustee (solely in its capacity as Trustee), may obtain at
the expense of the Trust any reasonably required analysis, Appraisals or market value estimates or other information for making
a recoverability determination. The determination by the Master Servicer, the Special Servicer or the Trustee, as the case may
be, that it has made a Nonrecoverable Servicing Advance or that any proposed Servicing Advance, if made, would constitute a Nonrecoverable
Servicing Advance, or any updated or changed recoverability determination, shall be evidenced by an Officer’s Certificate
delivered by either of the Special Servicer or the Master Servicer to the other and to the Trustee, the Certificate Administrator,
the Directing Certificateholder (but in the case of the Directing

 

    -95-

     

    

 

Certificateholder,
only prior to the occurrence and continuance of a Consultation Termination Event and only with respect to any Mortgage Loan other
than an Excluded Loan as to such party) (and in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any Other
Servicer or Non-Serviced Master Servicer, as applicable), the Operating Advisor (but only in the case of the Special Servicer)
and the Depositor, or by the Trustee to the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and the
Certificate Administrator (and in the case of a Serviced Mortgage Loan or Non-Serviced Mortgage Loan, any Other Servicer or Non-Serviced
Master Servicer, as applicable); provided, however, that the Special Servicer may, at its option, make a determination
in accordance with the Servicing Standard, that any Servicing Advance previously made or proposed to be made is a Nonrecoverable
Servicing Advance and shall deliver to the Master Servicer (and with respect to a Serviced Mortgage Loan, to any Other Servicer),
the Trustee, the Operating Advisor, the Certificate Administrator and the 17g-5 Information Provider notice of such determination.
Any such determination may be conclusively relied upon by, and shall be binding upon, the Master Servicer and the Trustee, provided,
however, that the Special Servicer shall not have such obligation to make an affirmative determination that any Servicing
Advance is or would be recoverable and in the absence of a determination by the Special Servicer that such Servicing Advance is
or would be a Nonrecoverable Servicing Advance, such decision shall remain with the Master Servicer or the Trustee, as applicable.
If the Special Servicer makes a determination that only a portion, and not all, of any previously made or proposed Servicing Advance
is a Nonrecoverable Servicing Advance, the Master Servicer and the Trustee shall each have the right to make its own subsequent
determination that any remaining portion of any such previously made or proposed Servicing Advance is a Nonrecoverable Servicing
Advance. The Officer’s Certificate shall set forth such determination of nonrecoverability and the considerations of the
Master Servicer, the Special Servicer or the Trustee, as applicable, forming the basis of such determination (which shall be accompanied
by, to the extent available, related income and expense statements, rent rolls, occupancy status and property inspections, and
shall include any existing Appraisal with respect to the related Mortgage Loan or Serviced Companion Loan, as applicable, or related
Mortgaged Property). The Special Servicer shall promptly furnish any party required to make Servicing Advances hereunder with
any information in its possession regarding the Specially Serviced Loans and REO Properties as such party required to make Servicing
Advances may reasonably request for purposes of making recoverability determinations. The Trustee shall be entitled to conclusively
rely on the Master Servicer’s or the Special Servicer’s, as the case may be, determination that a Servicing Advance
is or would be nonrecoverable, and the Master Servicer shall be entitled to conclusively rely on the Special Servicer’s
determination that a Servicing Advance is or would be nonrecoverable. Notwithstanding anything herein to the contrary, if the
Special Servicer requests that the Master Servicer make a Servicing Advance, the Master Servicer may conclusively rely on such
request as evidence that such advance is not a Nonrecoverable Servicing Advance; provided, however, that the Special
Servicer shall not be entitled to make such a request more frequently than once per calendar month with respect to Servicing Advances
other than emergency advances (although such request may relate to more than one Servicing Advance). In the case of a cross-collateralized
Mortgage Loan (if any), such recoverability determination shall take into account the cross-collateralization of the related cross-collateralized
Mortgage Loan. The determination as to the recoverability of any servicing advance previously made or proposed to be made in respect
of a Non-Serviced Whole Loan shall

 

    -96-

     

    

 

be
made by the related Non-Serviced Master Servicer, Non-Serviced Special Servicer or Non-Serviced Trustee, as the case may be, pursuant
to the Non-Serviced PSA.

Date; (iii) with respect to those Mortgage Loans that were closed in September 2017 but have their first Due Date in October 2017,
any interest amounts relating to the period prior to the Cut-off Date); and (iv) any Loan Seller Defeasance Rights and Obligations
with respect to the Mortgage Loans. The transfer of the Mortgage Loans and the related rights and property accomplished hereby
is absolute and, notwithstanding Section 13.07, is intended by the parties to constitute a sale. In connection with the
assignment to the Trustee of Sections 1, 2, 3, 4, 5 (excluding Section 5(e) and 5(f), 6(a) (excluding clauses (viii), (ix) and
(x) of Section 6(a)), 6(c), 6(e), 6(g), 6(h), 6(i), 11, 12, 16, 17, 18, 19, 20, 21 and 22 of each of the Mortgage Loan Purchase

Sections
11, 12 and 17 thereof in connection with any exercise of rights under the assigned Sections, and the Depositor shall use its best
efforts to make available to the Trustee the benefits of Sections 11, 12 and 17 in connection therewith.

 

(b)          In
connection with the Depositor’s assignment pursuant to subsection (a) above, the Depositor shall direct, and hereby
represents and warrants that it has directed, the Mortgage Loan Sellers pursuant to the applicable Mortgage Loan Purchase Agreement
to deliver to and deposit with, or cause to be delivered to and deposited with, the Custodian (or with respect to letters of credit,
the Master Servicer), on or before the Closing Date, the Mortgage File for each Mortgage Loan so assigned, with copies to the
Master Servicer (except, in the case of Serviced Mortgage Loans, for letters of credit, which are to be originals); 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. If the
applicable Mortgage Loan Seller cannot deliver, or cause to be delivered, as to any Mortgage Loan, the original Mortgage Note,
the delivery requirements of the applicable Mortgage Loan Purchase Agreement and this Section 2.01(b) shall be deemed to
have been satisfied upon such Mortgage Loan Seller’s delivery of a copy or duplicate original of such Mortgage Note, together
with an affidavit certifying that the original thereof has been lost or destroyed and indemnifying the Trustee and the Trust.
If the applicable Mortgage Loan Seller cannot deliver, or cause to be delivered, as to any Mortgage Loan, any of the documents
and/or instruments referred to in clauses (ii), (iv), (vii) (if recorded), (ix) and (x) of
the definition of “Mortgage File” (or, if applicable, a copy thereof) with evidence of filing or recording thereon
(if intended to be recorded or filed), solely because of a delay caused by the public filing or recording office where such document
or instrument has been delivered, or will be delivered within ten (10) Business Days of the Closing Date, for filing or recordation,
the delivery requirements of the applicable Mortgage Loan Purchase Agreement and this Section 2.01(b) shall be deemed to
have been satisfied on a provisional basis as of the Closing Date as to such non-delivered document or instrument, and such non-delivered
document or instrument shall be deemed to have been included in the Mortgage File, if a duplicate original or a photocopy of such
non-delivered document or instrument (certified by the applicable public filing or recording office, the applicable title insurance
company or the applicable Mortgage Loan Seller to be a true and complete copy of the original thereof submitted or to be submitted
for filing or recording) is delivered to the Custodian on or before the Closing Date, and either the original of such non-delivered
document or instrument, or a photocopy thereof (certified by the appropriate county recorder’s office or the applicable
title insurance company, in the case of the documents and/or instruments referred to in clause (ii) of the definition of
“Mortgage File”, to be a true and complete copy of the original thereof submitted for recording), with evidence of
filing or recording thereon, is delivered to the Custodian within one hundred-eighty (180) days of the Closing Date (or within
such longer period, not to exceed eighteen (18) months, after the Closing Date as the Custodian shall consent to as long as the
applicable Mortgage Loan Seller is, as certified in writing to the Trustee and the Custodian no less often than every ninety (90)
days following such 180–day period after the Closing Date, attempting in good faith to obtain from the appropriate public
filing office or county recorder’s office such original or photocopy). If the applicable Mortgage Loan Seller is required
to, but cannot, deliver, or cause to be delivered, as to any Mortgage Loan, any of the documents and/or instruments referred to
in clauses (ii), (iv), (vii) (if recorded), (ix) and (x) (or, if applicable, a copy thereof)
of the definition of “Mortgage File,” with evidence of filing or recording thereon

 

    -150-

     

    

 

(if
intended to be recorded or filed), for any other reason, including, without limitation, that such non-delivered document or instrument
has been lost or destroyed, the delivery requirements of the applicable Mortgage Loan Purchase Agreement and this Section 2.01(b)
shall be deemed to have been satisfied as to such non-delivered document or instrument, and such non-delivered document or
instrument shall be deemed to have been included in the Mortgage File, if a photocopy of such non-delivered document or instrument
(with evidence of filing or recording thereon and certified in the case of the documents and/or instruments referred to in clause
(ii) of the definition of “Mortgage File” by the appropriate county recorder’s office or the applicable
title insurance company to be a true and complete copy of the original thereof submitted for recording) is delivered to the Custodian
on or before the Closing Date. Neither the Trustee nor any Custodian shall in any way be liable for any failure by any Mortgage
Loan Seller or the Depositor to comply with the delivery requirements of the related Mortgage Loan Purchase Agreement and this
Section 2.01(b). If, on the Closing Date as to any Mortgage Loan, subject to the next sentence, the applicable Mortgage
Loan Seller is required to, but cannot, deliver (in complete and recordable form or form suitable for filing or recording, if
applicable) any one of the assignments in favor of the Trustee referred to in clause (iii), clause (v) (to the extent
not already assigned pursuant to clause (iii)) or clause (x) of the definition of “Mortgage File” solely
because of the unavailability of filing or recording information as to any existing document or instrument, such Mortgage Loan
Seller may provisionally satisfy the delivery requirements of the related Mortgage Loan Purchase Agreement and this Section
2.01(b) with respect to such assignment by delivering with respect to such Mortgage Loan on the Closing Date an omnibus assignment
substantially in the form of Exhibit H; provided that all required original assignments with respect to such Mortgage
Loan, (in fully complete and recordable form or form suitable for filing or recording, if applicable) are delivered to the Custodian
within one hundred-eighty (180) days after the Closing Date (or within such longer period, not to exceed eighteen (18) months,
which the Custodian shall consent to so long as the applicable Mortgage Loan Seller is, as certified in writing to the Trustee
and the Custodian no less often than every ninety (90) days following such 180–day period after the Closing Date, attempting
in good faith to obtain from the appropriate public filing office or county recorder’s office the applicable filing or recording
information as to the related document or instrument); and provided, further, that in the case of a Non-Serviced
Mortgage Loan, the delivery of any such assignments shall be subject to clause (e) of the final proviso to the definition
of “Mortgage File” herein. If, in accordance with the related Mortgage Loan Purchase Agreement and consistent with
Section 2.01(c) of this Agreement, as to any Mortgage Loan, the related Mortgage Loan Seller or its agent is responsible
for recording or filing, as applicable, any one of the assignments in favor of the Trustee referred to in clause (iii),
clause (v) (to the extent not already assigned pursuant to clause (iii)) or clause (x) of the definition
of “Mortgage File”, such Mortgage Loan Seller may provisionally satisfy the delivery requirements of the related Mortgage
Loan Purchase Agreement and this Section 2.01(b) with respect to such assignment by delivering to the Custodian with respect
to such Mortgage Loan on the Closing Date a copy of such assignment in the form sent for recording or filing or (except for recording
or filing information not yet available) to be sent for recording or filing; provided that an original or copy of such
assignment (with evidence of recording or filing, as applicable, indicated thereon) shall be delivered to the Custodian as contemplated
by Section 2.01(c) of this Agreement. Notwithstanding anything herein to the contrary, with respect to letters of credit
referred to in clause (xii) of the definition of “Mortgage File” and relating to a Serviced Mortgage Loan,
the applicable Mortgage Loan Seller shall deliver the original to the Master

Servicer
(which letter of credit shall be titled in the name of, or assigned to, “KeyBank National Association, as Master Servicer,
on behalf of Wells Fargo Bank, National Association, as Trustee, for the benefit of registered holders of CSAIL 2017-CX9 Commercial
Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2017-CX9, and a copy to the Custodian or, if such original
has been submitted by the applicable Mortgage Loan Seller to the issuing bank to effect a reissuance, assignment or amendment
of such letter of credit (changing the beneficiary thereof to the Master Servicer (in care of the Trustee, as titled above) that
may be required in order for the Master Servicer to draw on such letter of credit on behalf of the Trust in accordance with the
applicable terms thereof and/or of the related Mortgage Loan documents, as applicable) and the applicable Mortgage Loan Seller
shall be deemed to have satisfied the delivery requirements of the related Mortgage Loan Purchase Agreement and this Section
2.01(b) by delivering with respect to any letter(s) of credit a copy thereof to the Custodian together with an officer’s
certificate of the applicable Mortgage Loan Seller certifying that such document has been delivered to the issuing bank for reissuance
or an Officer’s Certificate from the Master Servicer certifying that it holds the letter(s) of credit pursuant to this Section
2.01(b), one of which shall be delivered to the Custodian on the Closing Date. If a letter of credit referred to in the previous
sentence is not in a form that would allow the Master Servicer to draw on such letter of credit on behalf of the Trust in accordance
with the applicable terms thereof and/or of the related Mortgage Loan documents, the applicable Mortgage Loan Seller shall deliver
the appropriate assignment or amendment documents (or copies of such assignment or amendment documents if the related Mortgage
Loan Seller has submitted the originals to the related issuer of such letter of credit for processing) to the Custodian within
thirty (30) days of the Closing Date. If not otherwise paid by the related Mortgagor, the applicable Mortgage Loan Seller shall
pay any costs of assignment or amendment of such letter(s) of credit required in order for the Master Servicer to draw on such
letter(s) of credit on behalf of the Trust and shall cooperate with the reasonable requests of the Master Servicer in connection
with effectuating a draw under any such letter of credit prior to the date such letter of credit is assigned or amended in order
that it may be drawn by the Master Servicer on behalf of the Trust.

 

(c)          Pursuant
to each Mortgage Loan Purchase Agreement, except in the case of a Non-Serviced Mortgage Loan, the related Mortgage Loan Seller
is required at its sole cost and expense, to itself, or to engage a third party to, put each Assignment of Mortgage, each assignment
of Assignment of Leases and each assignment of each UCC Financing Statement (collectively, the “Assignments”
and, individually, “Assignment”) relating to the Mortgage Loans conveyed by it under the applicable Mortgage
Loan Purchase Agreement in proper form for filing or recording, as applicable, and to submit such Assignments for filing or recording,
as the case may be, in the applicable public filing or recording office. On the Closing Date, the Mortgage Loan Sellers may deliver
one (1) omnibus assignment for all such Mortgage Loans substantially in the form of Exhibit H hereto to the Custodian as
provided in Section 2.01(b). Except under the circumstances provided for in the last sentence of this subsection (c)
and except in the case of a Non-Serviced Mortgage Loan, the related Mortgage Loan Seller will itself, or a third party at
such Mortgage Loan Seller’s expense will, promptly (and in any event within one hundred-twenty (120) days after the later
of the Closing Date and the related Mortgage Loan Seller’s actual receipt of the related documents and the necessary recording
and filing information) cause to be submitted for recording or filing, as the case may be, in the appropriate public office for
real property records or UCC Financing Statements, as appropriate, each Assignment. Each such Assignment submitted for recording
shall reflect that it (or a file copy

 

    -152-

     

    

 

thereof
in the case of a UCC Assignment) should be returned by the public recording office to the Custodian or its designee following
recording or filing (or to the related Mortgage Loan Seller or its agent who will then be responsible for delivery of the same
to the Custodian or its designee). Any such Assignment received by the Custodian shall be promptly included in the related Mortgage
File and be deemed a part thereof, and any such Assignment received by the related Mortgage Loan Seller or its agent shall be
required to be delivered to the Custodian to be included as part of the related Mortgage File within thirty (30) days after receipt.
If any such document or instrument is determined to be incomplete or not to meet the recording or filing requirements of the jurisdiction
in which it is to be recorded or filed, or is lost by the public office or returned unrecorded or unfiled, as the case may be,
because of a defect therein, on or about one hundred-eighty (180) days after the Closing Date, the related Mortgage Loan Seller
or its designee shall prepare, at its own expense, a substitute therefor or cure such defect, as the case may be, and thereafter
the related Mortgage Loan Seller or its designee shall, at the expense of such Mortgage Loan Seller, upon receipt thereof cause
the same to be duly recorded or filed, as appropriate. If, by the first anniversary of the Closing Date, the Custodian has not
received confirmation of the recording or filing as the case may be, of any such Assignment, it shall so advise the related Mortgage
Loan Seller who may then pursue such confirmation itself or request that the Custodian pursue such confirmation at the related
Mortgage Loan Seller’s expense, and upon such a request and provision for payment of such expenses satisfactory to the Custodian,
the Custodian, at the expense of the applicable Mortgage Loan Seller, shall cause a search of the land records of each applicable
jurisdiction and of the records of the offices of the applicable Secretary of State for confirmation that the Assignment appears
in such records and retain a copy of such confirmation in the related Mortgage File. In the event that confirmation of the recording
or filing of an Assignment cannot be obtained, the Custodian or the related Mortgage Loan Seller, as applicable, shall promptly
inform the other and the Custodian shall provide such Mortgage Loan Seller with a copy of the Assignment and request the preparation
of a new Assignment. The related Mortgage Loan Seller shall pay the expenses for the preparation of replacement Assignments for
any Assignments which, having been properly submitted for filing or recording to the appropriate governmental office by the Custodian,
fail to appear of record and must be resubmitted. Notwithstanding the foregoing, there shall be no requirement to record any assignment
to the Trustee referred to in clause (iii) or (v) of the definition of “Mortgage File,” or to file any
UCC-3 to the Trustee referred to in clause (ix) of the definition of “Mortgage File,” in those jurisdictions
where, in the written opinion of local counsel (which opinion shall be an expense of the related Mortgage Loan Seller) acceptable
to the Depositor and the Trustee, such recordation and/or filing is not required to protect the Trustee’s interest in the
related Mortgage Loan, against sale, further assignment, satisfaction or discharge by the related Mortgage Loan Seller, the Master
Servicer, the Special Servicer, any Sub-Servicer or the Depositor.

 

(d)          All
documents and records in the Depositor’s or the applicable Mortgage Loan Seller’s possession relating to the Mortgage
Loans (including, in each case, financial statements, operating statements and any other information provided by the respective
Mortgagor from time to time, but excluding the applicable Mortgage Loan Seller’s internal communications (including such
communications between such Mortgage Loan Seller and its Affiliates) and underwriting analysis (including documents prepared by
the applicable Mortgage Loan Seller or any of its Affiliates for such purposes), draft documents, attorney-client communications
that are privileged communications or constitute legal or other due diligence analyses and credit underwriting or due diligence
analyses or data) that (i) are not required to be a part of a Mortgage

with copies of all documents in each Mortgage File, shall be delivered by the Depositor or the applicable Mortgage Loan Seller
to the Master Servicer within five (5) Business Days after the Closing Date and shall be held by the Master Servicer on behalf
of the Trustee in trust for the benefit of the Certificateholders and, if applicable, on behalf of the related Companion Holder.
Such documents and records shall be any documents and records (with the exception of any items excluded under the immediately
preceding sentence) that would otherwise be a part of the Servicing File.

 

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

 

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

 

(g)          With
respect to the Mortgage Loans secured by the Mortgaged Properties identified as “The Boulders Resort & Spa”, “Hilton

are each subject to a franchise agreement with a related comfort letter in favor of the respective Mortgage Loan Seller that requires
notice to or request of the related franchisor to transfer or assign any related comfort letter to the Trust or otherwise have
a new comfort letter issued in the name of the Trust, the related Mortgage Loan Seller or its designee will be required to provide
any such required notice or make any such required request to the related franchisor (with a copy of such notice or request to
the Master Servicer) within 45 days of the Closing Date (or any shorter period if required by the applicable comfort letter),
and the Master Servicer shall use reasonable efforts in accordance with the Servicing Standard to acquire such replacement comfort
letter, if necessary (or to acquire any such new document or acknowledgement as may be contemplated under the existing comfort
letter). If the Master Servicer is unable to acquire any such replacement comfort letter (or new document or acknowledgement,
as applicable) within one hundred twenty (120) days of the Closing Date, the Master Servicer shall notify the related Mortgage
Loan Seller that no such replacement comfort letter has been received.

 

(h)          Each
Mortgage Loan Purchase Agreement shall provide that no later than sixty (60) days after the Closing Date, each Mortgage Loan Seller
shall deliver or cause to be

Promptly upon completion of such delivery of the Diligence Files (but in no event later than sixty (60) days after the Closing
Date), the applicable Mortgage Loan Seller shall provide to the Depositor a certificate (with a copy (which may be sent by email)
to each of the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Custodian, the Asset Representations
Reviewer and the Operating Advisor) certifying that the electronic copies of the Diligence File uploaded to the Designated Site

(j)           [Reserved].

 

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

 

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

the
Operating Advisor, the Asset Representations Reviewer and the applicable Mortgage Loan Seller (as to each Mortgage Loan listed
in the Mortgage Loan Schedule) that, except as specifically identified in any exception report annexed to such writing (the “Custodial
Exception Report”), (i) subject to the final proviso of the definition of “Mortgage File” herein and Section
2.01 hereof, all documents specified in clauses (i) through (v), (viii), (ix), (xi), (xii)

Certificate), if any, of the definition of “Mortgage File”, as applicable, are in its possession, (ii) the foregoing
documents delivered or caused to be delivered by the Mortgage Loan Sellers have been reviewed by the Custodian and appear regular
on their face and appear to be executed and to relate to such Mortgage Loan, and (iii) based on such examination and only as to
the foregoing documents, the information set forth in the Mortgage Loan Schedule with respect to the items specified in clauses
(iv), (vi) and (viii)(c) in the definition of “Mortgage Loan Schedule” is correct. With respect
to each Mortgage Loan listed on the Custodial Exception Report, the Custodian shall specifically identify such Mortgage Loan together
with the nature of such exception (in the form reasonably acceptable to the Custodian and the related Mortgage Loan Seller and
separating items required to be in the Mortgage File but never delivered from items which were delivered by the related Mortgage
Loan Seller but are out for filing or recording and have not been returned by the filing office or the recorder’s office).

 

(c)          The
Custodian shall review the Mortgage Loan documents received subsequent to the Closing Date; and, on or about the first anniversary
of the Closing Date, the Custodian shall, in the form attached as Exhibit Q, certify in writing to each of the Depositor,
the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Directing Holder (so long as no Consultation
Termination Event shall have occurred and be continuing and only with respect to the Mortgage Loans other than any Excluded Loan
with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority
of the Controlling Class), the Operating Advisor, the Asset Representations Reviewer and the applicable Mortgage Loan Seller (as
to each Mortgage Loan listed on the Mortgage Loan Schedule (other than any related Mortgage Loan as to which a Liquidation Event

subject to the final proviso of the definition of “Mortgage File” herein and Section 2.01 hereof, all documents
specified in clauses (i) through (v), (viii), (ix), (xi), (xii) and (xiii), if
any, of the definition of “Mortgage File”, as applicable, are in its possession, (ii) the foregoing documents delivered

the information set forth in the Mortgage Loan Schedule with respect to the items specified in clauses (iv), (vi)
and (viii)(c) in the definition of “Mortgage Loan Schedule” is correct.

 

(d)          Notwithstanding
anything contained in this Section 2.02 and Section 2.03(b) to the contrary, in the case of a Material Defect in
any of the documents specified in clauses (ii) through (v), (vii), (viii) and (ix) in the definition
of “Mortgage File”, which Material Defect results solely from a delay in the return of the related documents from
the applicable filing or recording office and gives rise to a repurchase or substitution obligation on the part of the related
Mortgage Loan Seller with respect to the subject Mortgage Loan pursuant to the related Mortgage Loan Purchase Agreement, the Directing
Holder, in its sole judgment,

 

    -156-

     

    

 

may
(other than with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing
Certificateholder, or the Holder of the majority of the Controlling Class and, with respect to any other Mortgage Loan, only prior
to the occurrence and continuance of a Control Termination Event), and the Special Servicer may, in accordance with the Servicing
Standard, after the occurrence and during the continuance of a Control Termination Event, permit the related Mortgage Loan Seller
in lieu of repurchasing or substituting for the related Mortgage Loan, to deposit with the Master Servicer an amount, to be held
in trust in a segregated Eligible Account (which may be a sub-account of the Collection Account), equal to 25% of the Stated Principal
Balance of the related Mortgage Loan (in the alternative, the related Mortgage Loan Seller may deliver to the Master Servicer
a letter of credit in such amount, with a copy to the Custodian). Such funds or letter of credit, as applicable, shall be held
by the Master Servicer (i) until the date on which the Custodian determines and notifies the Master Servicer that such Material
Defect has been cured or the related Mortgage Loan is no longer part of the Trust Fund, at which time the Master Servicer shall
return such funds (or letter of credit) to the related Mortgage Loan Seller, or (ii) until same are applied to the Purchase Price
(or the Substitution Shortfall Amount, if applicable) as set forth below in this Section 2.02(d) in the event of a repurchase
or substitution by the related Mortgage Loan Seller. Notwithstanding the two immediately preceding sentences, if the Master Servicer
or the Special Servicer certifies to the Trustee, the Certificate Administrator and the Custodian that it has determined in the
exercise of its reasonable judgment that the document with respect to which such Material Defect exists is required in connection
with an imminent enforcement of the mortgagee’s rights or remedies under the related Mortgage Loan defending any claim asserted
by any Mortgagor or third party with respect to the related Mortgage Loan, establishing the validity or priority of any lien on
collateral securing the related Mortgage Loan or for any immediate significant servicing obligation, the related Mortgage Loan
Seller shall be required to repurchase or substitute for the related Mortgage Loan in accordance with, and to the extent required
by, the terms and conditions of Section 2.03(b) and Section 6 of the related Mortgage Loan Purchase Agreement; provided,
however, that such Mortgage Loan Seller shall not be required to repurchase the Mortgage Loan for a period of ninety (90)
days after receipt of a notice to repurchase (together with any applicable extension period) if it is attempting to recover the
document from the applicable filing or recording office and provides an officer’s certificate setting forth what actions
such Mortgage Loan Seller is pursuing in connection with such recovery. In the event of a repurchase or substitution, upon the
date of such repurchase or substitution, and in the event that the related Mortgage Loan Seller has delivered a letter of credit
to the Master Servicer in accordance with this Section 2.02(d), the Master Servicer shall, to the extent necessary, draw
on the letter of credit and deposit the proceeds of such draw, into the Collection Account to be applied to the Purchase Price
(or the Substitution Shortfall Amount, if applicable, in which event, the amount of such funds or proceeds that exceed the Substitution
Shortfall Amount shall be returned to the related Mortgage Loan Seller) in accordance with Section 2.03(b). All such funds
deposited in the Collection Account shall be invested in Permitted Investments, at the direction and for the benefit of the related
Mortgage Loan Seller. Such funds shall be treated as an “outside reserve fund” under the REMIC Provisions, which,
together with any reimbursement from the Lower-Tier REMIC, is beneficially owned by the related Mortgage Loan Seller for federal
income tax purposes, which Mortgage Loan Seller shall remain liable for any taxes payable on income or gain with respect thereto.

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

 

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

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

 

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

 

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

 

In
the event that the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer
or the Custodian receives a Repurchase Request, such party shall promptly forward or otherwise provide written notice of such
Repurchase Request to the Master Servicer, if relating to a Non-Specially Serviced Loan, or to the Special Servicer, if relating
to a Specially Serviced Loan or REO Property, and include the following statement in the related correspondence: “This is
a ‘Repurchase Request’ under Section 2.02 of the Pooling and Servicing Agreement relating to the CSAIL 2017-CX9
Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2017-CX9 requiring action by you as the ‘Repurchase
Request Recipient’ thereunder.” Upon receipt of such Repurchase Request by the Master Servicer or the Special Servicer,
as applicable, such party shall be deemed to be the Repurchase Request Recipient in respect of such Repurchase Request, and such
party shall comply with the procedures set forth in this Section 2.02(g) with

 

    -159-

     

    

 

respect
to such Repurchase Request. In no event shall the Custodian, by virtue of this provision, be required to provide any notice other
than as set forth in Section 2.02 of this Agreement in connection with its review of the Mortgage File.

 

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

 

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

 

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

 

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

 

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

 

(iii)        The
execution and delivery of this Agreement and the performance of its obligations hereunder by the Depositor will not conflict with
any provisions of any law or regulations to which the Depositor is subject, or conflict with, result in a breach of or constitute
a default under any of the terms, conditions or provisions of the certificate of incorporation or the by-laws of the Depositor
or any indenture, agreement or instrument to which the Depositor is a party or by which it is bound, or any order or decree applicable
to

 

    -160-

     

    

 

the
Depositor, or result in the creation or imposition of any lien on any of the Depositor’s assets or property, which would
materially and adversely affect the ability of the Depositor to carry out the transactions contemplated by this Agreement; the
Depositor has obtained any consent, approval, authorization or order of any court or governmental agency or body required for
the execution, delivery and performance by the Depositor of this Agreement;

 

(iv)          There

or by or before any other governmental agency or instrumentality which would materially and adversely affect the validity of the
Mortgage Loans the ability of the Depositor to carry out the transactions contemplated by this Agreement; and

 

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

 

(b)          If
any Certificateholder, the Directing Holder, the Master Servicer, the Special Servicer, the Certificate Administrator, Operating
Advisor (solely in its capacity as Operating Advisor) or the Trustee discovers (without implying any duty of such person to make,
or to attempt to make, such a discovery) or receives notice alleging a Material Defect in any Mortgage File, such Certificateholder,
the Directing Holder, the Master Servicer, the Special Servicer, the Trustee, Operating Advisor (solely in its capacity as Operating
Advisor) or the Certificate Administrator, as applicable, shall give prompt written notice of such Material Defect to the Depositor,
the Master Servicer, the Special Servicer, the applicable Mortgage Loan Seller, the Trustee, the Certificate Administrator, the
Operating Advisor (solely in its capacity as Operating Advisor) and, prior to the occurrence of a Consultation Termination Event,
the Directing Holder, and 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), as applicable, shall request in writing that the applicable Mortgage
Loan Seller, not later than ninety (90) days after (i) except in the case of the succeeding clause (ii), the applicable
Mortgage Loan Seller’s discovery of the Material Defect or receipt of such notice or (ii) in the case of a Material Defect
relating to a Mortgage Loan not being a Qualified Mortgage, the earlier of (x) the discovery by the Mortgage Loan Seller or any
party to this Agreement of such Material Defect or (y) receipt of notice of a discovery of such Material Defect from any party
to this Agreement by the Mortgage Loan Seller, (such ninety (90) day period, the “Initial Cure Period”), (A)
cure such Material Defect in all material respects, at such Mortgage Loan Seller’s own expense, including reimbursement
of any related reasonable additional expenses of the Trust reasonably incurred by any party to this Agreement, (B) repurchase
the affected Mortgage Loan or REO Mortgage Loan (excluding any related Companion Loan, if applicable) at the applicable Purchase
Price and in conformity with the applicable Mortgage Loan Purchase Agreement and this Agreement or (C) substitute a Qualified
Substitute Mortgage Loan (other than with respect to any Mortgage Loan that is part of a Whole Loan, for which no substitution
will be permitted) for such affected Mortgage Loan or REO Mortgage Loan, and pay any Substitution Shortfall Amount in connection
with such substitution (provided that in no event shall any such substitution occur on or after the second anniversary
of the Closing Date) and pay the Master Servicer for deposit into the Collection Account, any Substitution Shortfall Amount in

 

    -161-

     

    

 

connection
therewith and in conformity with the applicable Mortgage Loan Purchase Agreement and this Agreement; provided, however,
that except with respect to a Material Defect resulting solely from the failure by the Mortgage Loan Seller to deliver to the
Trustee or Custodian the actual policy of lender’s title insurance required pursuant to clause (viii) of the definition
of Mortgage File by a date not later than eighteen (18) months following the Closing Date, if such Material Defect is capable
of being cured but is not cured within the Initial Cure Period, and the applicable Mortgage Loan Seller has commenced and is diligently
proceeding with the cure of such Material Defect within the Initial Cure Period, the applicable Mortgage Loan Seller shall have
an additional ninety (90) days commencing immediately upon the expiration of the Initial Cure Period (such additional ninety (90)
day period, the “Extended Cure Period”) to complete such cure (or, failing such cure, to repurchase the related
Mortgage Loan or REO Loan (excluding any related Serviced Companion Loan, if applicable) or substitute a Qualified Substitute
Mortgage Loan (other than with respect to any Mortgage Loan that is part of a Whole Loan, for which no substitution will be permitted)
and pay any Substitution Shortfall Amount in connection with such substitution) and provided, further, that with
respect to such Extended Cure Period the applicable Mortgage Loan Seller shall have delivered an officer’s certificate to
the Trustee, the Certificate Administrator (who shall promptly deliver a copy of such officer’s certificate to the 17g-5
Information Provider), the Master Servicer, the Special Servicer, the Operating Advisor and (with respect to any Mortgage Loan
other than an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder,
the Holder of the majority of the Controlling Class, prior to the occurrence and continuance of a Consultation Termination Event),
the Directing Holder, setting forth the reason such Material Defect is not capable of being cured within the Initial Cure Period
and what actions the applicable Mortgage Loan Seller is pursuing in connection with the cure thereof and stating that the applicable
Mortgage Loan Seller anticipates that such Material Defect will be cured within the Extended Cure Period; and provided,
further, that, if any such Material Defect is still not cured after the Initial Cure Period and any such Extended Cure
Period solely due to the failure of the Mortgage Loan Seller to have received the recorded document, then the Mortgage Loan Seller
shall be entitled to continue to defer its cure, substitution or repurchase obligations in respect of such Material Defect so
long as the Mortgage Loan Seller certifies to the Trustee, the Special Servicer, the Master Servicer and the Certificate Administrator
every 30 days thereafter that the Material Defect is still in effect solely because of its failure to have received the recorded
document and that the Mortgage Loan Seller is diligently pursuing the cure of such defect (specifying the actions being taken),
except that no such deferral of cure, substitution or repurchase may continue beyond the date that is 18 months following the
Closing Date. Any such repurchase or substitution of a Mortgage Loan shall be on a whole loan, servicing released basis. Notwithstanding
the foregoing, any Material Defect which causes any Mortgage Loan not to be a “qualified mortgage” (within the meaning
of Section 860G(a)(3) of the Code, but without regard to the rule of Treasury Regulations Section 1.860G-2(f)(2) that causes a
defective Mortgage Loan to be treated as a qualified mortgage) shall be deemed to materially and adversely affect the interests
of Certificateholders therein, and (subject to the applicable Mortgage Loan Seller’s right to cure such Material Defect
during the Initial Cure Period) such Mortgage Loan shall be repurchased or substituted for without regard to the Extended Cure
Period described in the preceding sentence. If the affected Mortgage Loan is to be repurchased, the funds in the amount of the
Purchase Price remitted by the applicable Mortgage Loan Seller are to be remitted by wire transfer to the Master Servicer for
deposit into the Collection Account.

 

    -162-

     

    

 

If
a Mortgage Loan Seller, in connection with a Material Defect (or an allegation of a Material Defect) pertaining to a Mortgage
Loan, makes a cash payment pursuant to an agreement or a settlement between the applicable Mortgage Loan Seller the Special Servicer
on behalf of the Trust (and, for so long as no Control Termination Event has occurred and is continuing and in respect of any
Mortgage Loan that is an Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder,
the Holder of the majority of the Controlling Class, the consent of the Directing Holder) (each such payment, a “Loss
of Value Payment”) with respect to such Mortgage Loan, the amount of such Loss of Value Payment shall be deposited into
the Loss of Value Reserve Fund to be applied in accordance with Section 3.05(g) of this Agreement. The Loss of Value Payment
shall include the portion of any Liquidation Fees payable to the Special Servicer in respect of such Loss of Value Payment and
the portion of fees and reimbursable expenses of the Asset Representations Reviewer attributable to the Asset Review of such Mortgage
Loan. If such Loss of Value Payment is made, the Loss of Value Payment shall serve as the sole remedy available to the Certificateholders
and the Trustee on their behalf regarding any such Material Defect in lieu of any obligation of the Mortgage Loan Seller to otherwise
cure such Material Defect or repurchase or substitute for the affected Mortgage Loan based on such Material Defect under any circumstances.
This paragraph is intended to apply only to a mutual agreement or settlement between the applicable Mortgage Loan Seller and the
Master Servicer (in the case of Non-Specially Serviced Loans) or the Special Servicer (in the case of Specially Serviced Loans)
on behalf of the Trust, provided that (i) prior to any such agreement or settlement nothing in this paragraph shall preclude
the Mortgage Loan Seller or the Master Servicer or the Special Servicer, as applicable, from exercising any of its rights related
to a Material Defect in the manner and timing set forth in the related Mortgage Loan Purchase Agreement or this Section 2.03
(excluding this paragraph) (including any right to cure, repurchase or substitute for such Mortgage Loan), (ii) such Loss
of Value Payment shall not be greater than the Purchase Price of the affected Mortgage Loan; and (iii) a Material Defect as a
result of a Mortgage Loan not constituting a Qualified Mortgage may not be cured by a Loss of Value Payment.

 

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

 

If
any Breach pertains to a representation or warranty that the related Mortgage Loan documents or any particular Mortgage Loan document
requires the related Mortgagor to bear the costs and expenses associated with any particular action or matter under such Mortgage
Loan document(s), then the related Mortgage Loan Seller may cure such Breach within the applicable cure period (as the same may
be extended) by reimbursing the Trust (by wire transfer of immediately available funds) for (i) the reasonable amount of any such
costs and expenses incurred by the Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee or the Trust
that are incurred as a result of such Breach and have not been reimbursed by the related Mortgagor and (ii) if such Mortgage Loan
is or was a Delinquent Loan subject to an Asset Review, the amount of any fees payable, without duplication, pursuant to Section
12.02(b)

 

    -163-

     

    

 

to
the extent not previously paid by the Mortgage Loan Seller to the Asset Representations Reviewer attributable to the Asset Review
of such Mortgage Loan; provided, however, that in the event any such costs and expenses exceed $10,000, the related
Mortgage Loan Seller shall have the option to either repurchase or substitute for the related Mortgage Loan as provided above
or pay such costs and expenses. Except as provided in the proviso to the immediately preceding sentence, the related Mortgage
Loan Seller shall remit the amount of such costs and expenses and upon its making such remittance, the related Mortgage Loan Seller
shall be deemed to have cured such Breach in all respects. To the extent any fees or expenses that are the subject of a cure by
the related Mortgage Loan Seller are subsequently obtained from the related Mortgagor, the portion of the cure payment made by
the related Mortgage Loan Seller equal to such fees or expenses obtained from the related Mortgagor shall promptly be returned
to the related Mortgage Loan Seller. Periodic Payments due with respect to each Qualified Substitute Mortgage Loan (if any) after
the related Due Date in the month of substitution, and Periodic Payments due with respect to each Mortgage Loan being repurchased
or replaced after the related Cut-off Date and received by the Master Servicer or the Special Servicer on behalf of the Trust
on or prior to the related date of repurchase or substitution, shall be part of the Trust Fund. Periodic Payments due with respect
to each Qualified Substitute Mortgage Loan (if any) on or prior to the related Due Date in the month of substitution, and Periodic
Payments due with respect to each Mortgage Loan being repurchased or replaced and received by the Master Servicer or the Special
Servicer on behalf of the Trust after the related date of repurchase or substitution, shall not be part of the Trust Fund and
are to be remitted by the Master Servicer or the Special Servicer to the applicable Mortgage Loan Seller effecting the related
repurchase or substitution promptly following receipt. Notwithstanding anything contained in this Agreement or the related Mortgage
Loan Purchase Agreement, no delay in either the discovery of a Material Defect or in providing notice of such Material Defect
shall relieve the applicable Mortgage Loan Seller of its obligation to cure, repurchase or substitute for (or make a Loss of Value
Payment with respect to) the related Mortgage Loan if it is otherwise required to do so under the related Mortgage Loan Purchase
Agreement and/or this Article II unless (i) the related Mortgage Loan Seller did not otherwise discover or have knowledge
of such Material Defect, (ii) such delay is a result of the failure by a party to the applicable Mortgage Loan Purchase Agreement,
or this Agreement (other than the Asset Representations Reviewer), to provide prompt notice as required by the terms of the applicable
Mortgage Loan Purchase Agreement, or this Agreement, after such party has actual knowledge of such Material Defect (knowledge
shall not be deemed to exist by reason of the Custodial Exception Report), (iii) such Material Defect does not relate to the applicable
Mortgage Loan not being a Qualified Mortgage and (iv) such delay precludes such Mortgage Loan Seller from curing such Material
Defect.

 

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

 

    -164-

     

    

 

REMIC
or the issuing entity and (iii) each applicable Rating Agency has provided a Rating Agency Confirmation.

 

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

 

    -165-

     

    

 

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

 

(d)         In
connection with any repurchase of, or substitution of a Qualified Substitute Mortgage Loan for a Mortgage Loan contemplated by
this Section 2.03, the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer
shall each tender to the applicable Mortgage Loan Seller, upon delivery to each of the Trustee, the Certificate Administrator,
the Custodian, the Master Servicer and the Special Servicer of a trust receipt executed by the applicable Mortgage Loan Seller
evidencing such repurchase or substitution, all portions of the Mortgage File and other documents pertaining to such Mortgage
Loan possessed by each of the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer
(other than attorney-client communications that are privileged communications), and each document that constitutes a part of the
Mortgage File that was endorsed or assigned to the Trustee shall be endorsed or assigned, as the case may be, to the applicable
Mortgage Loan Seller in the same manner as provided in Section 6 of the related Mortgage Loan Purchase Agreement and, if applicable,
the definition of “Mortgage File” herein, so as to vest in such Mortgage Loan Seller the legal and beneficial ownership
of such repurchased or substituted Mortgage Loan (including property acquired in respect thereof and proceeds of any insurance
policy with respect thereto) and the related Mortgage Loan documents.

 

(e)         Section
6 of each of the Mortgage Loan Purchase Agreements provides the sole remedy available to the Certificateholders (subject to the
limitations on the rights of the Certificateholders under this Agreement), or the Trustee on behalf of the Certificateholders,
the Master Servicer or the Special Servicer, with respect to any Defect in a Mortgage File or any Breach of any representation
or warranty with respect to a Mortgage Loan set forth in or required to be made pursuant to Section 6 of any of the Mortgage Loan
Purchase Agreements.

 

(f)          The
Master Servicer (in the case of Non-Specially Serviced Loans) or the Special Servicer (in the case of Specially Serviced Loans)
shall, for the benefit of the Certificateholders and the Trustee (as holder of the Lower-Tier Regular Interests), enforce the
obligations of the applicable Mortgage Loan Seller under the applicable Mortgage Loan Purchase Agreement. Such enforcement, including,
without limitation, the legal prosecution of claims, if any, shall be carried out in accordance with the Servicing Standard. Any
costs incurred by the Master Servicer or the Special Servicer with respect to the enforcement of the obligations of the applicable
Mortgage Loan Seller under the applicable Mortgage Loan Purchase Agreement shall, to the extent not recovered from the applicable
Mortgage Loan Seller, be deemed to be Servicing Advances to the extent not otherwise provided for herein. The Master Servicer
or the Special Servicer, as applicable, shall be reimbursed for the reasonable costs of such enforcement: first, from a
specific recovery, if any, of costs, expenses or attorneys’ fees

 

    -166-

     

    

 

against
the applicable Mortgage Loan Seller; second, pursuant to Section 3.05(a)(vii) herein out of the related Purchase
Price, to the extent that such expenses are a specific component thereof; and third, if at the conclusion of such enforcement
action it is determined that the amounts described in clauses first and second are insufficient, then pursuant
to Section 3.05(a)(viii) herein out of general collections on the Mortgage Loans on deposit in the Collection Account.
Any costs, expenses or attorneys’ fees related to a repurchase of a Companion Loan shall be paid pursuant to the related
Intercreditor Agreement or pursuant to the documents related to an Other Securitization, if applicable.

 

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

 

(h)          If
(i) any Crossed Underlying Loan is required to be repurchased or substituted for in the manner described in this Section 2.03
and (ii) the applicable Material Defect does not constitute a Material Defect as to any other Crossed Underlying Loan in the
related Crossed Mortgage Loan Group (without regard to this paragraph), then the applicable Material Defect shall be deemed to
constitute a Material Defect as to any other Crossed Underlying Loan in the related Crossed Mortgage Loan Group for purposes of
this paragraph, and the related Mortgage Loan Seller shall repurchase or substitute for such other Crossed Underlying Loan(s)
in the related Crossed Mortgage Loan Group as provided in Section 2.03(b) unless such other Crossed Underlying Loans satisfy
the Crossed Underlying Loan Repurchase Criteria. In the event that the remaining Crossed Underlying Loans in such Crossed Mortgage
Loan Group satisfy the Crossed Underlying Loan Repurchase Criteria, the applicable Mortgage Loan Seller may elect either to repurchase
or substitute for only the affected Crossed Underlying

 

    -167-

     

    

 

Loan(s)
as to which the related Material Defect exists or to repurchase or substitute for all of the Crossed Underlying Loans in the related
Crossed Mortgage Loan Group. Any reserve or other cash collateral or letters of credit securing the Crossed Underlying Loans shall
be allocated among the related Crossed Underlying Loans in accordance with the related Mortgage Loan documents or otherwise on
a pro rata basis based upon their outstanding Stated Principal Balances. Except as provided in this Section 2.03(h)
and Section 2.03(i), all other terms of the related Mortgage Loans shall remain in full force and effect without any
modification thereof.

 

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

 

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

 

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

 

    -168-

     

    

 

Master
Servicer (in the case of Non-Specially Serviced Loans) and the Special Servicer (in the case of Specially Serviced Loans) (the
“Enforcing Servicer”) shall be the Enforcing Party with respect to a Certificateholder Repurchase Request.

 

(ii)          In
the event that the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator or the Operating
Advisor (solely in its capacity as Operating Advisor) obtains knowledge of a Material Defect with respect to a Mortgage Loan,
that party shall deliver prompt written notice of such Material Defect to each other party to this Agreement identifying the applicable
Mortgage Loan and setting forth the basis for such allegation (an “PSA Party Repurchase Request” and, either
a Certificateholder Repurchase Request or a PSA Party Repurchase Request, the “Repurchase Request”) and the
Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans)
will be required to promptly send the PSA Party Repurchase Request to the related Mortgage Loan Seller. Prior to the occurrence
of a Resolution Failure, the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect
to Specially Serviced Loans) shall act as the Enforcing Party and enforce the rights of the Trust against the related Mortgage
Loan Seller with respect to a PSA Party Repurchase Request.

 

(iii)         In
the event the Repurchase Request is not Resolved within 180 days after the Mortgage Loan Seller receives the Repurchase Request
(a “Resolution Failure”), then the provisions described in Section 2.03(l) below shall apply. Receipt
of the Repurchase Request shall be deemed to occur two (2) Business Days after the Repurchase Request is sent to the related Mortgage
Loan Seller.

 

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

 

(l)          (i)
After a Resolution Failure occurs with respect to a Repurchase Request regarding a Mortgage Loan (whether the Repurchase Request
was initiated by an Initial Requesting Certificateholder or by a party to this Agreement), the Enforcing Servicer will be required
to send a notice (a “Proposed Course of Action Notice”) to the Initial Requesting Certificateholder, if any,
to the address specified in the Initial Requesting Certificateholder’s Repurchase Request, and to the Certificate Administrator
(which shall be delivered via electronic mail to trustadministrationgroup@wellsfargo.com) who shall make such notice available
to all other Certificateholders and Certificate Owners (by posting such notice on the Certificate Administrator’s Website)
indicating the Enforcing Servicer’s intended course of action with respect to the Repurchase Request (a “Proposed
Course of Action”). Such notice shall include (a) a request to Certificateholders to indicate their agreement with or
dissent from such Proposed Course of Action by clearly marking “agree” or “disagree” to the Proposed Course
of Action on such notice within 30 days of the date of such notice and a disclaimer that responses received after such 30-day
period shall not be taken into consideration, (b) a statement that in the event any Certificateholder disagrees with the Proposed
Course of Action, the Enforcing Servicer shall

 

    -169-

     

    

 

be
compelled to follow or accept the course of action agreed to and/or proposed by the majority of the responding Certificateholders
that involves referring the matter to mediation or arbitration, as the case may be, (c) a statement that responding Certificateholders
will be required to certify their holdings in connection with such response, (d) a statement that only responses clearly marked
“agree” or “disagree” with such Proposed Course of Action will be taken into consideration and (e) instructions
for responding Certificateholders to send their responses to the applicable Enforcing Servicer and the Certificate Administrator.
If (a) the Enforcing Servicer’s intended course of action with respect to the Repurchase Request does not involve pursuing
further action to exercise rights against the applicable Mortgage Loan Seller with respect to the Repurchase Request but the Initial
Requesting Certificateholder, if any, or any other Certificateholder or Certificate Owner wishes to exercise its right to refer
the matter to mediation (including nonbinding arbitration) or arbitration, or (b) the Enforcing Servicer’s intended course
of action is to pursue further action to exercise rights against the applicable Mortgage Loan Seller with respect to the Repurchase
Request but the Initial Requesting Certificateholder, if any, or any other Certificateholder or Certificate Owner does not agree
with the dispute resolution method selected by the Enforcing Servicer, then the Initial Requesting Certificateholder, if any,
or such other Certificateholder or Certificate Owner may deliver to the Enforcing Servicer a written notice (a “Preliminary
Dispute Resolution Election Notice”) within 30 days from the date the Proposed Course of Action Notice is posted on
the Certificate Administrator’s Website (the “Dispute Resolution Cut-off Date”) indicating its intent
to exercise its right to refer the matter to either mediation or arbitration. In the event any Certificateholder or Certificate
Owner delivers a Preliminary Dispute Resolution Election Notice, and the Enforcing Servicer has also received responses from other
Certificateholders or Certificate Owners supporting the Enforcing Servicer’s initial Proposed Course of Action, such responses
shall be considered Preliminary Dispute Resolution Election Notices supporting the Proposed Course of Action. The Certificate
Administrator shall within three (3) Business Days after the expiration of the 30-day response period, tabulate the responses
received from the Certificateholders and share the results with the Enforcing Servicer. The Certificate Administrator shall only
count responses timely received and clearly indicating agreement or dissent with the related Proposed Course of Action and additional
verbiage or qualifying language shall not be taken into consideration for purposes of determining whether the related Certificateholder
agrees or disagrees with the Proposed Course of Action. The Certificate Administrator shall be under no obligation to answer any
questions from Certificateholders regarding such Proposed Course of Action. For the avoidance of doubt, the Certificate Administrator’s
obligations in connection with this Section 2.03(l) shall be limited solely to tabulating Certificateholder responses of
“agree” or “disagree” to the Proposed Course of Action, and such obligation shall not be construed to
impose any enforcement obligation on the Certificate Administrator. The Enforcing Servicer may conclusively rely (without investigation)
on the Certificate Administrator’s tabulation of the majority of the responding Certificateholders.

 

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

 

    -170-

     

    

 

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

 

(iv)         If,
following the Dispute Resolution Consultation, no Requesting Certificateholder timely delivers a Final Dispute Resolution Election
Notice to the Enforcing Servicer, then the Enforcing Servicer will continue to act as the Enforcing Party and will remain obligated
under this Agreement to enforce the rights of the Trust with respect to the Repurchase Request and no Certificateholder or Certificate
Owner shall have any further right to elect to refer the matter to mediation or arbitration.

 

(v)          If
a Requesting Certificateholder timely delivers a Final Dispute Resolution Election Notice to the Enforcing Servicer, then such
Requesting Certificateholder shall become the Enforcing Party and must promptly submit the matter to mediation (including nonbinding
arbitration) or arbitration. If there are more than one Requesting Certificateholder that timely deliver a Final Dispute Resolution
Election Notice, then such Requesting Certificateholders will collectively become the Enforcing Party, and the holder or holders
of a majority of the Voting Rights among such Requesting Certificateholders will be entitled to make all decisions relating to
such mediation or arbitration. If, however, no Requesting Certificateholder commences arbitration or mediation pursuant to the
terms of this Agreement within 30 days after delivery of its Final Dispute Resolution Election Notice to the Enforcing Servicer,
then (i) the rights of a Requesting Certificateholder to act as the Enforcing Party shall terminate and no Certificateholder or
Certificate Owner shall have any further right to elect to refer the matter to mediation or arbitration, (ii) if the Proposed
Course of Action Notice indicated that the Enforcing Servicer shall take no further action with respect to the Repurchase Request,
then the related Material Defect shall be deemed waived for all purposes under this Agreement and the related Mortgage Loan Purchase
Agreement, and (iii) if the Proposed Course of Action Notice had indicated a course of action other than the course of action
under clause (ii), then the Enforcing Servicer shall again become the Enforcing Party and, as such, shall be the sole party entitled
to enforce the Trust’s rights against the related Mortgage Loan Seller.

 

    -171-

     

    

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

    -172-

     

    

 

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

 

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

 

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

 

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

 

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

 

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

 

(vi)         The
arbitrator shall make its final determination no later than 30 days after the conclusion of the hearings and submission of any
post-hearing submissions. The arbitrator shall resolve the dispute in accordance with the terms of the related Mortgage

 

    -173-

     

    

 

Loan
Purchase Agreement and this Agreement, and may not modify or change those agreements in any way or award remedies not consistent
with those agreements. The arbitrator will not have the power to award punitive damages or consequential damages in any arbitration
conducted by them. Interest on any monetary award shall bear interest from the date of the Final Dispute Resolution Election Notice
at the Prime Rate. In its final determination, the arbitrator shall determine and award the costs of the arbitration (including
the fees of the arbitrator, cost of any record or transcript of the arbitration, and administrative fees) and shall award reasonable
attorneys’ fees to the parties to the arbitration as determined by the arbitrator in its reasonable discretion. The determination
of the arbitrator shall be by a reasoned decision in writing and counterpart copies will be promptly delivered to the parties.
The final determination of the arbitrator shall be final and non-appealable, except for actions to confirm or vacate the determination
permitted under federal or state law, and may be enforced in any court of competent jurisdiction.

 

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

 

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

 

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

 

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

 

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

 

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

 

    -174-

     

    

 

regulatory
body) for such confidential information, the recipient shall promptly notify the other party to the resolution procedure and shall
provide the other party with a reasonable opportunity to object to the production of its confidential information.

 

(iv)         In
the event a Requesting Certificateholder is the Enforcing Party, the agreement with the arbitrator or mediator, as the case may
be, shall be required to contain an acknowledgment that the Trust, or the Enforcing Servicer on its behalf, shall be a party to
any arbitration or mediation proceedings solely for the purpose of being the beneficiary of any award in favor of the Enforcing
Party; provided that the degree and extent to which the Enforcing Servicer actively prepares for and participates in such
proceeding shall be determined by such Enforcing Servicer in consultation with the Directing Holder (provided that no Consultation
Termination Event has occurred and is continuing and an Excluded Loan is not involved), and in accordance with the Servicing Standard.
All amounts recovered by the Enforcing Party shall be paid to the Trust, or the Enforcing Servicer on its behalf, and deposited
in the Collection Account. The agreement with the arbitrator or mediator, as the case may be, shall provide that in the event
a Requesting Certificateholder is allocated any related costs and expenses pursuant to the terms of the arbitrator’s decision
or the agreement reached in mediation, neither the Trust nor the Enforcing Servicer acting on its behalf shall be responsible
for any such costs and expenses allocated to the Requesting Certificateholder.

 

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

 

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

 

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

 

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

 

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

the benefit of the Certificateholders and, in the case of the Serviced Companion Loans, the Companion Holders and the Trustee
(as holder of the Lower-Tier Regular Interests) and the Trustee, in each case, as a collective whole, taking into account the
subordinate or pari passu nature
of such Companion Loans, as the case may be (as determined by the Master Servicer or the Special Servicer, as the case may be,
in its reasonable judgment), in accordance with applicable law, the terms of this Agreement (and, with respect to each Serviced
Whole Loan or any Mortgage Loan with related mezzanine debt, the related Intercreditor Agreement) and the terms of the respective
Mortgage Loans and, if applicable, the related Companion Loan, taking into account the subordinate or pari
passu nature of the Companion Loan, as the case may be. With respect to each Serviced Whole
Loan, in the event of a conflict between this Agreement and the related Intercreditor Agreement, the related Intercreditor Agreement
shall control; 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 Intercreditor Agreement that would cause the Master Servicer
or the Special Servicer, as the case may be, to violate the Servicing Standard or the REMIC Provisions. To the extent consistent
with the foregoing, the Master Servicer and the Special Servicer shall service the Mortgage Loans (other than any Non-Serviced
Mortgage Loan) and the Serviced Companion Loans in accordance with the higher of the following standards of care: (1) in the same
manner in which, and with the same care, skill, prudence and diligence with which the Master Servicer or the Special Servicer,

prudence and diligence with which the Master Servicer or the Special Servicer, as the case may be, services and administers similar
mortgage loans owned by the Master Servicer or the Special Servicer, as the case may be, with a view to the (A) the timely recovery
of all payments of principal and interest under the Mortgage Loans or Serviced Whole Loans or (B) in the case of a Specially Serviced
Loan or an REO Property, maximization of timely recovery of principal and interest on a net present value basis on such Mortgage

whole as if such Certificateholders constituted a single lender) (and in the case of any Whole Loan, the best interests of the
Trust, the Certificateholders and any related Companion Holder (as a collective whole as if such Certificateholders and the holder
or holders of the related Companion Loan constituted a single lender), taking into account the subordinate or pari passu nature
of the related Companion Loan), as determined by the Master Servicer or the Special Servicer, as the case may be, in its reasonable
judgment, in either case giving due consideration to the customary and usual standards of practice of prudent institutional commercial,
multifamily and manufactured housing community mortgage loan servicers, but

 

    -177-

     

    

 

without
regard to any conflict of interest arising from: (i) any relationship that the Master Servicer, the Special Servicer or any Affiliate
of the Master Servicer or the Special Servicer may have with any Mortgagor or any Affiliate of such Mortgagor, any Mortgage Loan
Seller, any other parties to this Agreement, any Sponsor, any originator of a Mortgage Loan or any Affiliate of any of the foregoing;
(ii) the ownership of any Certificate, Companion Loan, mezzanine loan, or subordinate debt relating to a Mortgage Loan by the
Master Servicer, the Special Servicer or any Affiliate of the Master Servicer or the Special Servicer, as applicable; (iii) the
obligation, if any, of the Master Servicer to make Advances; (iv) the right of the Master Servicer or the Special Servicer, as
the case may be, or any of its Affiliates to receive compensation for its services and reimbursement for its costs hereunder or
with respect to any particular transaction; (v) the ownership, servicing or management for others of (a) the Non-Serviced Mortgage
Loans and the Non-Serviced Companion Loans or (b) any other mortgage loans, subordinate debt, mezzanine loans or properties not
covered by this Agreement or held by the Trust by the Master Servicer or the Special Servicer, as the case may be, or any of its
Affiliates; (vi) any debt that the Master Servicer or the Special Servicer, as the case may be, or any of its Affiliates, has
extended to any Mortgagor or an Affiliate of any Mortgagor (including, without limitation, any mezzanine financing); (vii) any
option to purchase any Mortgage Loan or the related Companion Loan the Master Servicer or the Special Servicer, as the case may
be, or any of its Affiliates, may have; and (viii) any obligation of the Master Servicer or the Special Servicer, or any of their
respective Affiliates, to repurchase, substitute or make a Loss of Value Payment with respect to a Mortgage Loan as a Mortgage
Loan Seller (if the Master Servicer or the Special Servicer or any of their respective Affiliates is a Mortgage Loan Seller) (the
foregoing, collectively referred to as the “Servicing Standard”).

 

The
Master Servicer and the Special Servicer shall act in accordance with the Servicing Standard with respect to any action required
to be taken regarding the Non-Serviced Mortgage Loans pursuant to their obligations under this Agreement.

 

Without
limiting the foregoing, subject to Section 3.19, the Special Servicer shall be obligated to service and administer (i)
any Mortgage Loans (other than the Non-Serviced Mortgage Loans, except in the case of Section 2.03(f) and Section 2.03(k)
through Section 2.03(o)), any related Serviced Companion Loans as to which a Servicing Transfer Event has occurred
and is continuing (each, a “Specially Serviced Loan”) or as otherwise provided herein with respect to Non-Specially
Serviced Loans in connection with any Major Decision and (ii) any REO Properties (other than the Non-Serviced Mortgaged Properties);
provided that the Master Servicer shall continue to receive payments and make all calculations, and prepare, or cause to
be prepared, all reports, required hereunder with respect to the Specially Serviced Loans, except for the reports specified herein
as prepared by the Special Servicer, as if no Servicing Transfer Event had occurred and with respect to the REO Properties (and
the related REO Loans) as if no REO Acquisition had occurred, and to render such services with respect to such Specially Serviced
Loans and REO Properties as are specifically provided for herein; provided, further, however, that the Master
Servicer shall not be liable for failure to comply with such duties insofar as such failure results from a failure of the Special
Servicer to provide sufficient information to the Master Servicer to comply with such duties or failure by the Special Servicer
to otherwise comply with its obligations hereunder. The Master Servicer, in its capacity as Master Servicer, will not have any
responsibility for the performance by the Special Servicer, in its capacity as Special Servicer, of its duties under this Agreement.
The Special Servicer, in

 

    -178-

     

    

 

its
capacity as Special Servicer, will not have any responsibility for the performance by the Master Servicer, in its capacity as
Master Servicer, of its duties under this Agreement. Each Mortgage Loan or any related Serviced Companion Loan that becomes a
Specially Serviced Loan shall continue as such until satisfaction of the conditions specified in Section 3.19(a). Without
limiting the foregoing, subject to (i) the processing of any Major Decision or Special Servicer Decision by the Special Servicer
in accordance with the terms of this Agreement and (ii) Section 3.19, the Master Servicer shall be obligated to service
and administer any Non-Specially Serviced Loan or any related Serviced Companion Loan. The Special Servicer shall make the property
inspections, use its reasonable efforts to collect the financial statements, budgets, operating statements and rent rolls and
forward to the Master Servicer the reports in respect of the related Mortgaged Properties with respect to Specially Serviced Loans
in accordance with Section 3.12. After notification to the Master Servicer, the Special Servicer may contact the Mortgagor
of any Non-Specially Serviced Loan if efforts by the Master Servicer to collect required financial information have been unsuccessful
or any other issues remain unresolved. Such contact shall be coordinated through and with the cooperation of the Master Servicer.
No provision herein contained shall be construed as an express or implied guarantee by the Master Servicer or the Special Servicer
of the collectability or recoverability of payments on the Mortgage Loans or any related Serviced Companion Loan or shall be construed
to impair or adversely affect any rights or benefits provided by this Agreement to the Master Servicer or the Special Servicer
(including with respect to Servicing Fees, Special Servicing Fees or the right to be reimbursed for Advances and interest accrued
thereon). Any provision in this Agreement for any Advance by the Master Servicer or the Trustee is intended solely to provide
liquidity for the benefit of the Certificateholders and not as credit support or otherwise to impose on any such Person the risk
of loss with respect to one or more of the Mortgage Loans or any related Serviced Companion Loans. No provision hereof shall be
construed to impose liability on the Master Servicer or the Special Servicer for the reason that any recovery to the Certificateholders
in respect of a Mortgage Loan at any time after a determination of present value recovery is less than the amount reflected in
such determination.

 

(b)       Subject
only to the Servicing Standard and the terms of this Agreement (including, without limitation, Section 6.08) and of the
respective Mortgage Loans or any related Serviced Companion Loans and any related Intercreditor Agreement, if applicable, and
applicable law, the Master Servicer and the Special Servicer each shall have full power and authority, acting alone or, in the
case of the Master Servicer, subject to Section 3.20, through one or more Sub-Servicers, to do or cause to be done any
and all things in connection with such servicing and administration for which it is responsible which it may deem necessary or
desirable. Without limiting the generality of the foregoing, each of the Master Servicer and the Special Servicer, in its own
name (or in the name of the Trustee and, if applicable, the related Serviced Companion Noteholder), is hereby authorized and empowered
by the Trustee to execute and deliver, on behalf of the Certificateholders (and, with respect to a Serviced Companion Loan, the
related Serviced Companion Noteholder) and the Trustee or any of them, with respect to each Mortgage Loan, any related Serviced
Companion Loan, it is obligated to service under this Agreement: (i) any and all financing statements, continuation statements
and other documents or instruments necessary to maintain the lien created by the related Mortgage or other security document in
the related Mortgage File on the related Mortgaged Property and related collateral, and shall, from time to time, execute and/or
deliver such financing statements, continuation statements and other documents or instruments as necessary to maintain the lien

 

    -179-

     

    

 

created
by the related Mortgage or other security document in the related Mortgage File on the related Mortgaged Property and related
collateral; (ii) subject to Sections 3.08, 3.18 and 6.08, any and all modifications, waivers, amendments
or consents to, under or with respect to any documents contained in the related Mortgage File; (iii) any and all instruments of
satisfaction or cancellation, pledge agreements and other documents in connection with a defeasance, or of partial or full release
or discharge, and all other comparable instruments; and (iv) any or all complaints or other pleadings to initiate and/or to terminate
any action, suit or proceeding on behalf of the Trust (in their representative capacities (except as set forth below in this paragraph).
The Master Servicer (with respect to Non-Specially Serviced Loans) and the Special Servicer (with respect to Specially Serviced
Loans) shall provide to the Mortgagor related to such Mortgage Loans that it is servicing any reports required to be provided
to them pursuant to the related Mortgage Loan documents. Subject to Section 3.10, the Trustee shall (i) on the Closing
Date, furnish to the Master Servicer and the Special Servicer original powers of attorney in the form of Exhibit R attached
hereto (or such other form as mutually agreed to by the Trustee and the Master Servicer or the Special Servicer, as applicable)
and (ii) upon request, furnish, or cause to be furnished, to the Master Servicer or the Special Servicer any powers of attorney
substantially in the form of Exhibit R attached hereto (or such other form as mutually agreed to by the Trustee and the
Master Servicer or the Special Servicer, as applicable) and other documents necessary or appropriate to enable the Master Servicer
or the Special Servicer, as the case may be, to carry out its servicing and administrative duties hereunder; provided,
however, that the Trustee shall not be held responsible or liable for any acts of the Master Servicer or the Special Servicer,
or for any negligence with respect to, or misuse of, any such power of attorney by the Master Servicer or the Special Servicer.
Notwithstanding anything contained herein to the contrary, the Master Servicer or the Special Servicer, as the case may be, shall
not, without the Trustee’s written consent: (i) initiate any action, suit or proceeding solely under the Trustee’s
name without indicating the Master Servicer’s or the Special Servicer’s, as the case may be, representative capacity
(unless prohibited by any requirement of the applicable jurisdiction in which any such action, suit or proceeding is brought and
if so prohibited, in the manner required by such jurisdiction (provided that the Master Servicer or the Special Servicer,
as applicable, shall then provide five (5) Business Days’ written notice to the Trustee of the initiation of such action,
suit or proceeding (or such shorter time period as is reasonably required in the judgment of the Master Servicer or the Special
Servicer, as applicable, made in accordance with the Servicing Standard) prior to filing such action, suit or proceeding), and
shall not be required to obtain the Trustee’s consent or indicate the Master Servicer’s or the Special Servicer’s,
as applicable, representative capacity)) or (ii) take any action with the intent to cause, and that actually causes, the Trustee
to be required to be registered to do business in any state.

 

(c)       To
the extent the Master Servicer is permitted pursuant to the terms of the related Mortgage Loan documents or Companion Loan documents
(including any related Intercreditor Agreement) to exercise its discretion with respect to any action that requires Rating Agency
Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will not result in
the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities (if
any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency
Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25), the Master Servicer
shall require the costs of such Rating Agency Confirmation to be borne by the related Mortgagor. To the extent the terms of the
related Mortgage Loan

 

    -180-

     

    

 

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

 

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

 

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

 

(f)       Within
sixty (60) days (or such shorter time period as is required by the terms of the applicable Mortgage Loan documents) after the
later of (i) the receipt thereof by the Master Servicer and (ii) the Closing Date, (x) the applicable Mortgage Loan Seller pursuant
to the Mortgage Loan Purchase Agreement shall notify each provider of a letter of credit for each Mortgage Loan identified as
having a letter of credit on the Mortgage Loan Schedule, that the Master Servicer (in care of the Trustee, as titled in Section
2.01(b)) for the benefit of the Certificateholders and any related Companion Holders shall be the beneficiary under each such
letter of credit and (y) the Master Servicer shall notify each lessor under a Ground Lease for each Mortgage Loan identified as
subject to a leasehold interest on the Mortgage Loan Schedule, that the Trust is the leasehold mortgagee, that any notices of
default under such Ground Lease and required to be delivered to the leasehold mortgagee pursuant to the terms of such Ground Lease
shall be delivered to the Master Servicer (who shall forward such notice to the Special Servicer), and that the Master Servicer
or the Special Servicer shall service the related Mortgage Loan for the benefit of the Certificateholders. If a letter of credit
is required to be drawn upon earlier than the date the applicable Mortgage Loan Seller has notified the provider of such letter
of credit pursuant to clause (x) of the immediately preceding sentence, such Mortgage Loan Seller shall cooperate with
the reasonable requests of the Master Servicer or Special Servicer in connection with making a draw under such letter of credit.
If the Mortgage Loan documents do not require the related Mortgagor to pay any costs and expenses relating to any modifications
to or assignment of the related letter of credit, then the applicable Mortgage Loan Seller shall pay such

 

    -181-

     

    

 

costs
and expenses as and to the extent required under the applicable Mortgage Loan Purchase Agreement. If the Mortgage Loan documents
require the related Mortgagor to pay any costs and expenses relating to any modifications to the related letter of credit, and
such Mortgagor fails to pay such costs and expenses after the Master Servicer has exercised reasonable efforts to collect such
costs and expenses from such Mortgagor, then the Master Servicer shall give the applicable Mortgage Loan Seller notice of such
failure and the amount of costs and expenses, and such Mortgage Loan Seller shall pay such costs and expenses as and to the extent
required under the applicable Mortgage Loan Purchase Agreement. The costs and expenses of any modifications to Ground Leases shall
be paid by the related Mortgagor. Neither the Master Servicer nor the Special Servicer shall have any liability for the failure
of any Mortgage Loan Seller to perform its obligations under the related Mortgage Loan Purchase Agreement.

 

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

 

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

 

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

 

(j)        Notwithstanding
anything herein to the contrary, the parties hereto acknowledge and agree that, to the extent required under the related Intercreditor
Agreement, the servicing and administration of a Serviced Whole Loan shall continue hereunder (but not with respect to making
Advances) even if the related Serviced Mortgage Loan is no longer part of the Trust Fund, until such time as a separate servicing
agreement is entered into in accordance with the related Intercreditor Agreement (it being acknowledged that neither the Master
Servicer nor the Special Servicer shall be obligated under a separate agreement to which it is not a party);

 

    -182-

     

    

 

provided
that, other than pursuant to Section 6.04 (and, with respect to Section 6.04, solely with respect to claims,
losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, liabilities, fees
and expenses incurred in connection with a legal claim or action resulting from an action or inaction taken or not taken while
the related Serviced Mortgage Loan was part of the Trust Fund), no costs, expenses, losses or fees accruing with respect to such
Serviced Whole Loan on and after the date the related Serviced Mortgage Loan is no longer part of the Trust Fund shall be payable
out of the Trust Fund and the Master Servicer shall have no obligation to make any Advance on or after the date such Serviced
Mortgage Loan ceases to be part of the Trust Fund; provided, however, that if, in the case of any Serviced Whole
Loan, the related Serviced Companion Loan continues to be included in an Other Securitization, then for so long as a separate
servicing agreement (pursuant to the related Intercreditor Agreement) has not been entered into, the Master Servicer shall inform
the related Other Servicer of any need to make Servicing Advances with respect to a Serviced Whole Loan within three (3) Business
Days of determining that such an Advance is necessary or being notified that such an Advance is necessary, or in the case of a
Servicing Advance that needs to be made on an emergency or urgent basis, within one (1) Business Day. With respect to Servicing
Advances made by any Other Servicer as contemplated in the second proviso to the preceding sentence, the Master Servicer shall,
from collections on the related Serviced Whole Loan (but never out of general collections on the Mortgage Loans and REO Properties)
received by the Master Servicer, reimburse the Other Servicer for such Servicing Advances in the same manner and on the same level
of priority as if such Servicing Advances had been made by the Master Servicer hereunder.

 

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

 

(l)         The
parties hereto acknowledge that each Non-Serviced Mortgage Loan is subject to the terms and conditions of the related Non-Serviced
Intercreditor Agreement and further acknowledge that, pursuant to the related Non-Serviced Intercreditor Agreement, (i) the related
Non-Serviced Mortgage Loan is to be serviced and administered by the related Non-Serviced Master Servicer and Non-Serviced Special
Servicer in accordance with the related Non-Serviced PSA, and (ii) in the event that (A) the related Non-Serviced Companion Loan
is no longer part of the Trust Fund created by the related Non-Serviced PSA and (B) the related Non-Serviced Mortgage Loan is
included in the Trust Fund, then, as set forth in the related Non-Serviced Intercreditor Agreement, the related Non-Serviced Whole
Loan shall continue to be serviced in accordance with the related Non-Serviced PSA, until such time as a new servicing agreement
has been agreed to by the parties to the related Non-Serviced Intercreditor Agreement in accordance with the provisions of such
agreement and confirmation has been obtained from the Rating Agencies that such new servicing agreement would not result in a
downgrade,

 

    -183-

     

    

 

qualification
or withdrawal of the then-current ratings of any Class of Certificates then outstanding.

 

(m)      Notwithstanding
anything herein to the contrary, the parties hereto acknowledge and agree that the Master Servicer’s and the Special Servicer’s
obligations and responsibilities hereunder and the Master Servicer’s and the Special Servicer’s authority with respect
to a Serviced Whole Loan are limited by, and subject to, the terms of the related Intercreditor Agreement. The Master Servicer
(or, if a Serviced Whole Loan becomes a Specially Serviced Loan, the Special Servicer) shall use reasonable efforts consistent
with the Servicing Standard to obtain the benefits of the rights of the Trust (as holder of the related Serviced Mortgage Loan)
under the related Intercreditor Agreement. In the event of any conflict between this Agreement and the related Intercreditor Agreement,
the provisions of the related Intercreditor Agreement shall control.

 

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

 

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

 

(b)       (i)
All amounts collected by or on behalf of the Trust in respect of a Mortgage Loan shall be applied to amounts due and owing under
the Mortgage Loan documents (including for principal and accrued and unpaid interest) in accordance with the express provisions
of the Mortgage Loan documents; provided, however, that absent express provisions in the related Mortgage Loan documents
(including any related Intercreditor Agreement) or to the extent otherwise agreed to by the related Mortgagor in connection with
the workout of a

 

    -184-

     

    

 

Mortgage
Loan, all amounts collected by or on behalf of the Trust in respect of a Mortgage Loan in the form of payments from the related
Mortgagor, Liquidation Proceeds or Insurance and Condemnation Proceeds under the Mortgage Loan (in the case of each Serviced Whole
Loan, exclusive of amounts payable to any applicable Companion Loan pursuant to the terms of the related Intercreditor Agreement)
shall be applied in the following order of priority:

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

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

 

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

 

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

 

    -186-

     

    

 

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

 

second,
as a recovery of Nonrecoverable Advances and any interest on those Nonrecoverable Advances at the Reimbursement Rate, to the extent
previously paid or reimbursed from principal collections on the Mortgage Loans;

 

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

 

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

 

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

 

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

 

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

 

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

 

ninth,
as a recovery of any other amounts then due and owing under such Mortgage Loan other than, if applicable, accrued and unpaid Excess
Interest (if both consent fees

 

    -187-

     

    

 

and
Operating Advisor Consulting Fees are due and owing, first,
allocated to consent fees and then,
allocated to Operating Advisor Consulting Fees); and

 

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

 

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

 

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

 

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

 

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

 

(e)       With
respect to any Mortgage Loan in connection with which the Mortgagor was required to escrow funds or to post a letter of credit
related to obtaining certain performance objectives described in the applicable Mortgage Loan documents, the Master Servicer shall,
to the extent consistent with the Servicing Standard, hold such escrows, letters of

 

    -188-

     

    

 

credit
and proceeds thereof as additional collateral and not apply such items to reduce the principal balance of such Mortgage Loan or
Serviced Companion Loan, unless otherwise required to do so pursuant to the applicable Mortgage Loan documents, applicable law
or court order.

 

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

 

Section
3.03 Collection of Taxes, Assessments and Similar Items; Servicing Accounts. (a) The Master Servicer shall establish and
maintain one or more accounts (the “Servicing Accounts”), into which all Escrow Payments shall be deposited
and retained, and shall administer such Servicing Accounts in accordance with the Mortgage Loan documents and, if applicable,
the Companion Loan documents, as the case may be. Any Servicing Account related to a Serviced Whole Loan shall be held for the
benefit of the Certificateholders and the related Serviced Companion Noteholder collectively, but this shall not be construed
to modify respective interests of either noteholder therein as set forth in the related Intercreditor Agreement. Amounts on deposit
in Servicing Accounts may only be invested in accordance with the terms of the related Mortgage Loan documents and Companion Loan
documents, as applicable, or in Permitted Investments in accordance with the provisions of Section 3.06. Servicing Accounts
shall be Eligible Accounts to the extent permitted by the terms of the related Mortgage Loan documents. Withdrawals of amounts
so deposited from a Servicing Account may be made only to: (i) effect payment of items for which Escrow Payments were collected
and comparable items; (ii) reimburse the Trustee and then the Master Servicer, if applicable, for any Servicing Advances; (iii)
refund to Mortgagors any sums as may be determined to be overages; (iv) pay interest to Mortgagors on balances in the Servicing
Account, if required by applicable law or the terms of the related Mortgage Loan or Companion Loan and as described below or,
if not so required, to the Master Servicer; (v) after the occurrence of an event of default under the related Mortgage Loan or
Companion Loan, apply amounts to the indebtedness under the applicable Mortgage Loan or Companion Loan; (vi) withdraw amounts
deposited in error; (vii) pay Penalty Charges to the extent permitted by the related Mortgage Loan documents; or (viii) clear
and terminate the Servicing Account at the termination of this Agreement in accordance with Section 9.01. As part of its
servicing duties, the Master Servicer shall pay or cause to be paid to the Mortgagors interest on funds in Servicing Accounts,
to the extent required by law or the terms of the related Mortgage Loan or Companion Loan; provided, however, that
in no event shall the Master Servicer be required to remit to any Mortgagor any amounts in excess of actual net investment income
or funds in the related Servicing Account. If allowed by

 

    -189-

     

    

 

the
related Mortgage Loan documents and applicable law, the Master Servicer may charge the related Mortgagor an administrative fee
for maintenance of the Servicing Accounts.

 

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

 

(c)       In
accordance with the Servicing Standard and for each Mortgage Loan (other than any Non-Serviced Mortgage Loans) and each Serviced
Whole Loan, the Master Servicer shall advance all such funds as are necessary for the purpose of effecting the payment of (i)
real estate taxes, assessments and other similar items that are or may become a lien thereon, (ii) ground rents (if applicable)
and (iii) premiums on Insurance Policies, in each instance if and to the extent Escrow Payments collected from the related Mortgagor
(or related REO Revenues, if applicable) are insufficient to pay such item when due and the related Mortgagor has failed to pay
such item on a timely basis, and provided, however, that the particular advance would not, if made, constitute a
Nonrecoverable Servicing Advance and provided, further, however, that with respect to the payment of taxes
and assessments, the Master Servicer shall not be required to make such advance until the later of (i) five (5) Business Days
after the Master Servicer, the Special Servicer, the Certificate Administrator or the Trustee, as the case may be, has received
confirmation that such item has not been paid and (ii) the date prior to the date after which any

 

    -190-

     

    

 

penalty
or interest would accrue in respect of such taxes or assessments. The Special Servicer shall give the Master Servicer and the
Trustee no less than five (5) Business Days’ written (facsimile or electronic) notice before the date on which the Master
Servicer is requested to make any Servicing Advance with respect to a given Specially Serviced Loan or REO Property; provided,
however, that only two (2) Business Days’ written (facsimile or electronic) notice shall be required in respect of
Servicing Advances required to be made on an emergency or urgent basis provided, further, that the Special Servicer
shall not be entitled to make such a request (other than for Servicing Advances required to be made on an urgent or emergency
basis) more frequently than once per calendar month (although such request may relate to more than one Servicing Advance). The
Master Servicer may pay the aggregate amount of such Servicing Advances listed on a monthly request to the Special Servicer, in
which case the Special Servicer shall remit such Servicing Advances to the ultimate payees. The Special Servicer shall have no
obligation to make any Servicing Advances; provided that in an urgent or emergency situation requiring the making of a
Servicing Advance, the Special Servicer may make a Servicing Advance. Within five (5) Business Days of making such a Servicing
Advance, the Special Servicer shall deliver to the Master Servicer request for reimbursement for such Servicing Advance, along
with all information and documentation in the Special Servicer’s possession regarding the subject Servicing Advance as the
Master Servicer may reasonably request, and the Master Servicer shall be obligated, out of such Master Servicer’s own funds,
to reimburse the Special Servicer for any unreimbursed Servicing Advances (other than Nonrecoverable Servicing Advances) made
by the Special Servicer pursuant to the terms hereof), together with interest thereon at the Reimbursement Rate from the date
made to, but not including, the date of reimbursement. Such reimbursement and any accompanying payment of interest shall be made
within five (5) Business Days of the written request therefor pursuant to the preceding sentence by wire transfer of immediately
available funds to an account designated in writing by the Special Servicer. Upon the Master Servicer’s reimbursement to
the Special Servicer of any Servicing Advance and payment to the Special Servicer of interest thereon, all in accordance with
this Section 3.03, the Master Servicer shall for all purposes of this Agreement be deemed to have made such Servicing Advance
at the same time as the Special Servicer actually made such Servicing Advance, and accordingly, the Master Servicer shall be entitled
to be reimbursed for such Servicing Advance, together with interest thereon at the Reimbursement Rate, at the same time, in the
same manner and to the same extent as the Master Servicer would otherwise have been entitled if it had actually made such Servicing
Advance at the time the Special Servicer did. Notwithstanding the foregoing provisions of this Section 3.03, the Master
Servicer shall not be required to reimburse the Special Servicer for any such Servicing Advance if the Master Servicer determines
in accordance with the Servicing Standard that such Servicing Advance, although not characterized by the Special Servicer as a
Nonrecoverable Servicing Advance, is in fact a Nonrecoverable Servicing Advance. The Master Servicer shall notify the Special
Servicer in writing of such determination and, if applicable, such Nonrecoverable Servicing Advance shall be reimbursed to the
Special Servicer pursuant to Section 3.05 of this Agreement.

 

Any
request by the Special Servicer that the Master Servicer make a Servicing Advance shall be deemed to be a determination by the
Special Servicer that such requested Servicing Advance is not a Nonrecoverable Servicing Advance, and the Master Servicer shall
be entitled to conclusively rely on such determination; provided that the determination shall not be binding on the Master
Servicer or Trustee. On the first Business Day after the Determination Date for the related Distribution Date, the Special Servicer
shall report to the Master Servicer if

 

    -191-

     

    

 

the
Special Servicer determines any Servicing Advance previously made by the Master Servicer with respect to a Specially Serviced
Loan or REO Loan is a Nonrecoverable Servicing Advance and such non-recoverability determination shall be binding upon the Master
Servicer. Notwithstanding anything to the contrary in this Agreement, in the absence of any determination by the Special Servicer
that a Servicing Advance previously made by the Master Servicer with respect to a Specially Serviced Loan or REO Loan is a Nonrecoverable
Servicing Advance, the Master Servicer shall be permitted to make its own determination that any such Servicing Advance is a Nonrecoverable
Advance. If the Special Servicer makes a determination that only a portion of, and not all of, any previously made or proposed
Servicing Advance is a Nonrecoverable Advance, the Master Servicer shall have the right to make its own subsequent determination
that any remaining portion of any such previously made or proposed Servicing Advance is a Nonrecoverable Advance. All such Advances
shall be reimbursable in the first instance from related collections from the Mortgagors and further as provided in Section
3.05(a). No costs incurred by the Master Servicer or the Special Servicer in effecting the payment of real estate taxes, assessments
and, if applicable, ground rents on or in respect of the Mortgaged Properties shall, for purposes hereof, including, without limitation,
the Certificate Administrator’s calculation of monthly distributions to Certificateholders, be added to the unpaid principal
balances of the related Mortgage Loans or any related Serviced Companion Loan, if applicable, notwithstanding that the terms of
such Mortgage Loans or related Serviced Companion Loan, if applicable, so permit. If the Master Servicer fails to make any required
Servicing Advance as and when due (including any applicable cure periods), to the extent the Trustee has actual knowledge of such
failure, the Trustee shall make such Servicing Advance pursuant to Section 7.05. Notwithstanding anything herein to the
contrary, no Servicing Advance shall be required hereunder if such Servicing Advance would, if made, constitute a Nonrecoverable
Servicing Advance. In addition, the Master Servicer shall consider Unliquidated Advances in respect of prior Servicing Advances
for purposes of nonrecoverability determinations. The Special Servicer shall have no obligation to make any Servicing Advances
under this Agreement.

 

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

 

Notwithstanding
anything to the contrary contained in this Section 3.03(c), the Master Servicer may in its good faith judgment elect (but
shall not be required unless directed by the Special Servicer with respect to Specially Serviced Loans and REO Loans) to make
a payment from amounts on deposit in the Collection Account (or any Companion Distribution Account maintained as a subaccount
thereof by a Companion Paying Agent, if applicable) (which shall be deemed first
made from amounts distributable as principal and then
from all other amounts comprising general collections) to pay for certain expenses set forth
below notwithstanding that the Master Servicer (or the Special Servicer, as applicable) has determined that a Servicing Advance
with respect to such expenditure would be a Nonrecoverable Servicing

 

    -192-

     

    

 

Advance
(unless, with respect to Specially Serviced Loans or REO Loans, the Special Servicer has notified the Master Servicer to not make
such expenditure), where making such expenditure would prevent (i) the related Mortgaged Property from being uninsured or being
sold at a tax sale or (ii) any event that would cause a loss of the priority of the lien of the related Mortgage, or the loss
of any security for the related Mortgage Loan or Serviced Companion Loan; provided that in each instance, the Master Servicer
or the Special Servicer, as applicable, determines in accordance with the Servicing Standard (as evidenced by an Officer’s
Certificate delivered to the Trustee) that making such expenditure is in the best interest of the Certificateholders (and, if
applicable, the Companion Holders), all as a collective whole (taking into account the subordinate or pari
passu nature of any Companion Loans, as the case may be). The Master Servicer or Trustee may
elect to obtain reimbursement of Nonrecoverable Servicing Advances from the Trust pursuant to the terms of Section 3.17(c).
The parties acknowledge that pursuant to the applicable Non-Serviced PSA, the applicable Non-Serviced Master Servicer is obligated
to make servicing advances with respect to the related Non-Serviced Whole Loan. The applicable Non-Serviced Master Servicer shall
be entitled to reimbursement for Nonrecoverable Servicing Advances with respect to such Non-Serviced Whole Loan (with, in each
case, any accrued and unpaid interest thereon provided for under the applicable Non-Serviced PSA) in the manner set forth in the
applicable Non-Serviced PSA and the applicable Non-Serviced Intercreditor Agreement.

 

(d)       In
connection with its recovery of any Servicing Advance out of the Collection Account (or any Companion Distribution Account maintained
as a subaccount thereof by the Companion Paying Agent, if applicable) pursuant to Section 3.05(a), the Trustee, the Special
Servicer and then the Master Servicer, as the case may be and in that order, shall be entitled to receive, out of any amounts
then on deposit in the Collection Account interest at the Reimbursement Rate in effect from time to time, accrued on the amount
of such Servicing Advance from the date made to, but not including, the date of reimbursement. Subject to Section 3.17(c),
the Master Servicer shall reimburse itself, the Special Servicer or the Trustee, as the case may be, for any outstanding Servicing
Advance as soon as practically possible after funds available for such purpose are deposited in the Collection Account (or any
Companion Distribution Account maintained as a subaccount thereof by the Companion Paying Agent, if applicable) subject to the
Master Servicer’s or the Trustee’s options and rights to defer recovery of such amounts as provided herein; provided,
however, that such Master Servicer’s or Trustee’s options and rights to defer recovery of such amounts shall
not alter the Master Servicer’s obligation to reimburse the Special Servicer for any outstanding Servicing Advance as provided
for in this sentence. To the extent amounts on deposit in the Companion Distribution Account with respect to the related Companion
Loan are insufficient for any such reimbursement, the Master Servicer shall use reasonable efforts in accordance with the Servicing
Standard to enforce the rights of the holder of the related Mortgage Loan under the related Intercreditor Agreement to obtain
any reimbursement available from the holder of the related Companion Loan.

 

(e)       To
the extent an operations and maintenance plan is required to be established and executed pursuant to the terms of a Mortgage Loan
(other than a Non-Serviced Mortgage Loan), the Master Servicer shall request from the Mortgagor written confirmation thereof within
a reasonable time after the later of the Closing Date and the date as of which plan is required to be established or completed.
To the extent any repairs, capital improvements, actions or remediations are required to have been taken or completed pursuant
to the terms of the

 

    -193-

     

    

 

Mortgage
Loan (other than a Non-Serviced Mortgage Loan), the Master Servicer shall request from the Mortgagor written confirmation of such
actions and remediations within a reasonable time after the later of the Closing Date and the date as of which action or remediations
are required to be or to have been taken or completed. To the extent a Mortgagor shall fail to promptly respond to any inquiry
described in this Section 3.03(e), the Master Servicer shall report any such failure to the Special Servicer within a reasonable
time after the date as of which actions or remediations are required to be or to have been taken or completed.

 

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

 

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

 

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

 

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

 

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

 

    -194-

     

    

 

securitization)
together with any recovery of Unliquidated Advances in respect of the related Mortgage Loans;

 

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

 

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

 

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

 

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

 

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

 

Upon
receipt of any of the foregoing amounts in clauses (i) through (iv) above with respect to any Specially Serviced
Loans, the Special Servicer shall remit within one (1) Business Day such amounts to the Master Servicer for deposit into the Collection
Account, in accordance with this Section 3.04(a). Any such amounts received by the Special Servicer with respect to an
REO Property shall be deposited by the Special Servicer into the REO Account and remitted to the Master Servicer for deposit into
the Collection Account, pursuant to Section 3.14(c). With respect to any such amounts paid by check to the order of the
Special Servicer, the Special Servicer shall endorse without recourse or warranty such check to the order of the Master Servicer
and shall promptly deliver any such check to the Master Servicer by overnight courier. Funds in the Collection Account may only
be invested in Permitted Investments in accordance with the provisions of Section 3.06. As of the Closing Date, the Collection
Account for the Master Servicer shall be located at the offices of KeyBank National Association. The Master Servicer shall give

(b)       The

Holders of the Class Z Certificates), (ii) the Upper-Tier REMIC Distribution Account in trust for the benefit of the Certificateholders
(other than the Holders of the Class Z Certificates), (iii) the Regular Interest Distribution Account in trust for the benefit
of the Certificateholders (other than the Holders of the Class R and Class Z Certificates), and (iv) the Excess Interest Distribution

deliver to the Certificate Administrator each month on or before the P&I Advance Date therein, for deposit (x) in the Lower-Tier
REMIC Distribution Account, that portion of the Available Funds attributable to the Mortgage Loans (in each case, calculated without
regard to clauses (a)(iii)(B), (a)(iv), (c) and (d) of the definition of Available Funds) for, and
any Yield Maintenance Charges with respect to the Mortgage Loans distributable on, the related Distribution Date, and (y) in the
Excess Interest Distribution Account all Excess Interest for the related Distribution Date then on deposit in the Collection Account
after giving effect to withdrawals of funds pursuant to Section 3.05(a)(ii). For the avoidance of doubt, so long as Wells
Fargo Bank, National Association is the Certificate Administrator, all funds held in the Distribution Accounts, the Interest Reserve
Account and the Excess Interest Distribution Account shall remain uninvested.

 

With
respect to each Companion Loan (excluding any Non-Serviced Companion Loan), the Companion Paying Agent shall establish and maintain
the Companion Distribution Account, which may be a subaccount of the Collection Account, for distributions to each Companion Holder,
to be held for the benefit of the related Companion Holder and shall, within two (2) Business Days following the Companion Paying
Agent’s receipt of properly identified and available funds, deposit in the Companion Distribution Account any and all amounts
received by the Companion Paying Agent that are required by the terms of this Agreement or the applicable Intercreditor Agreement
to be deposited therein; provided, however, that the Companion Paying Agent shall separately track for each Serviced
Companion Loan all amounts deposited with respect to such Serviced Companion Loan. The Master Servicer shall deliver to the Companion
Paying Agent each month, on or before the P&I Advance Date therein, for deposit in the Companion Distribution Account, an
aggregate amount of immediately available funds, to the extent received with respect to the related Serviced Whole Loan, to the
extent of available funds, equal to the amount to be distributed to the related Companion Holder pursuant to the terms of this
Agreement and the related Intercreditor Agreement. Notwithstanding the preceding, the following provisions shall apply to remittances
relating to the Serviced Companion Loans that have been deposited into an Other Securitization: (1) on each Serviced Whole Loan
Remittance Date, the Master Servicer shall withdraw from the Collection Account (or applicable
portion thereof) an aggregate amount equal to all payments and/or collections actually received on, and payable to, such Serviced
Companion Loans prior to such dates; provided, however, that in no event shall the Master Servicer be required to
transfer to the Companion Distribution Account any portion thereof that is payable or reimbursable to or at the direction of any
party to this Agreement under the other provisions of this Agreement and/or the related Intercreditor Agreement; and (2) on each
Serviced Whole Loan Remittance Date, the

 

    -196-

     

    

 

Companion
Paying Agent shall make the payments and remittance described in Section 4.01(k), which payments and remittance shall be
made, in each case, on the Serviced Whole Loan Remittance Date. In addition, with respect to any amounts that represent Late Collections
on a Companion Loan for which a P&I Advance has already been paid by a master servicer or trustee under any Other Pooling
and Servicing Agreement, the Master Servicer shall remit such Late Collections to such master servicer or trustee under such Other
Pooling and Servicing Agreement, as applicable, within two Business Days of receipt of properly identified funds.

 

The
Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the
Excess Interest Distribution Account, the Gain-on-Sale Reserve Account, the Interest Reserve Account and the Companion Distribution
Account may be subaccounts of a single Eligible Account, which shall be maintained as a segregated account separate from other
accounts.

 

In
addition to the amounts required to be deposited in the Lower-Tier REMIC Distribution Account pursuant to this Section 3.04,
the Master Servicer shall, as and when required hereunder, deliver to the Certificate Administrator for deposit in the Lower-Tier
REMIC Distribution Account:

 

(i)             any
amounts required to be deposited by the Master Servicer pursuant to Section 3.17(a) as Compensating Interest Payments (other
than the portion of any Compensating Interest Payment allocated to a Serviced Pari Passu Companion Loan) in connection with Prepayment
Interest Shortfalls;

 

(ii)            any
P&I Advances required to be made by the Master Servicer in accordance with Section 4.03;

 

(iii)           any
Liquidation Proceeds paid by the Master Servicer, the Special Servicer, the Holders of the Controlling Class or the Holders of
the Class R Certificates in connection with the purchase of all of the Mortgage Loans and any REO Properties in the Trust Fund
pursuant to Section 9.01 (exclusive of that portion thereof required to be deposited in the Collection Account pursuant
to Section 9.01);

 

(iv)           any
Yield Maintenance Charges with respect to the Mortgage Loans actually collected; and

 

(v)            any
other amounts required to be so delivered for deposit in the Lower-Tier REMIC Distribution Account pursuant to any provision of
this Agreement.

 

If,
as of the close of business (New York City time) on any P&I Advance Date or on such other date as any amount referred to in
the foregoing clauses (i) through (v) or any Excess Interest are required to be delivered hereunder, the Master
Servicer shall not have delivered to the Certificate Administrator for deposit in the Lower-Tier REMIC Distribution Account, the
amounts required to be deposited therein pursuant to the provisions of this Agreement (including any P&I Advance with respect
to the Mortgage Loans, pursuant to Section 4.03(a)), the Master Servicer shall pay the Certificate Administrator interest
on such late payment at the Prime Rate from and including the date such payment was required to be made

 

    -197-

     

    

 

(without
regard to any Grace Period set forth in Section 7.01(a)(i)) until (but not including) the date such late payment is received
by the Certificate Administrator.

 

The
Certificate Administrator shall, upon receipt, deposit in the Lower-Tier REMIC Distribution Account, any and all amounts received
by the Certificate Administrator that are required by the terms of this Agreement to be deposited therein.

 

Promptly
on each Distribution Date, the Certificate Administrator shall be deemed to withdraw from the Lower-Tier REMIC Distribution Account
and deposit in the Upper-Tier REMIC Distribution Account an aggregate amount of immediately available funds equal to the Lower-Tier
Distribution Amount and the amount of any Yield Maintenance Charges for such Distribution Date allocated in payment of the Lower-Tier
Regular Interests as specified in Section 4.01(c) and Section 4.01(d), respectively.

 

Funds
on deposit in the Gain-on-Sale Reserve Account, the Interest Reserve Account, the Excess Interest Distribution Account, the Upper-Tier
REMIC Distribution Account or the Lower-Tier REMIC Distribution Account shall not be invested for so long as Wells Fargo Bank,
National Association is the Certificate Administrator; provided, however, that such funds may be invested and, if
invested, shall be invested by, and at the risk of, the Certificate Administrator (but only if the Certificate Administrator is
not Wells Fargo Bank, National Association) in Permitted Investments selected by the party hereunder that maintains such account
which shall mature, unless payable on demand, not later than such time on the Distribution Date which will allow the Certificate
Administrator to make withdrawals from the Distribution Account, and any such Permitted Investment shall not be sold or disposed
of prior to its maturity unless payable on demand. All such Permitted Investments to be administered by the Certificate Administrator
shall be made in the name of “Wells Fargo Bank, National Association, as Certificate Administrator, for the benefit of Wells
Fargo Bank, National Association, as Trustee for the Holders of the CSAIL 2017-CX9 Commercial Mortgage Trust, Commercial Mortgage
Pass-Through Certificates, Series 2017-CX9 as their interests may appear”, or in the name of any successor trustee, as Trustee
for the Holders of the CSAIL 2017-CX9 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2017-CX9
as their interests may appear. None of the Trust, the Depositor, the Mortgagors, the Master Servicer or the Special Servicer shall
be liable for any loss incurred on such Permitted Investments.

 

An
amount equal to all income and gain realized from any such investment shall be paid to the Certificate Administrator as additional
compensation and shall be subject to its withdrawal at any time from time to time. The amount of any losses incurred in respect
of any such investments shall be for the account of the Certificate Administrator which shall deposit the amount of such loss
(to the extent not offset by income from other investments) in the Distribution Accounts, as the case may be, out of its own funds
immediately as realized. If the Certificate Administrator deposits in or transfers to the Distribution Accounts, as the case may
be, any amount not required to be deposited therein or transferred thereto, it may at any time withdraw such amount or retransfer
such amount from the Distribution Accounts, as the case may be, any provision herein to the contrary notwithstanding.

On
the Closing Date, the Depositor shall deposit $250,000 with the Certificate Administrator, to be credited to the Legal Fee Reserve
Account. Funds held in the Legal Fee Reserve Account shall remain uninvested. Annually, on or about April 1st beginning
2018, upon receipt by the Certificate Administrator from the Depositor of a legal invoice related to Commission compliance matters,
the Certificate Administrator shall pay such legal invoice from and solely to the extent of funds then on deposit in the Legal
Fee Reserve Account. Any such instruction shall be sent by email to cts.cmbs.bond.admin@wellsfargo.com, along with a copy of the
invoice, and a subject line reference of “CSAIL 2017-CX9 - Legal Fee Reserve Account”. The Legal Fee Reserve Account

Legal Fee Reserve Account for all federal income tax purposes, and shall be taxable on all income earned therefrom.

 

Upon
the depletion of the Legal Fee Reserve Account, or if there are insufficient funds to pay any invoice, the Certificate Administrator
shall notify the Depositor, and thereafter the Depositor shall pay any additional legal invoices from its own funds and the Certificate
Administrator shall have no responsibility in connection therewith.

 

The
Certificate Administrator shall have no responsibility for verifying the accuracy, reasonableness, or appropriateness of any invoice
received. On the final Distribution Date, the Certificate Administrator shall pay to the Depositor any funds then remaining in
the Legal Fee Reserve Account in accordance with directions provided by the Depositor

 

As

Account, the Lower-Tier REMIC Distribution Account and the Regular Interest Distribution Account shall be located at the offices
of the Certificate Administrator. The Certificate Administrator shall give notice to the Trustee, the Master Servicer and the
Depositor of the proposed location of the Interest Reserve Account, the Excess Interest Distribution Account, the Upper-Tier REMIC
Distribution Account, the Lower-Tier REMIC Distribution Account, the Regular Interest Distribution Account and, if established,
the Gain-on-Sale Reserve Account prior to any change thereof.

 

For
the avoidance of doubt, the Collection Account (other than (i) any portion holding Excess Interest and (ii) the Companion Distribution
Account, if it is a sub-account of the Collection Account), the Lower-Tier REMIC Distribution Account, the Gain-on-Sale Reserve
Account, any Servicing Account, the REO Account and the Interest Reserve Account (including interest, if any, earned on the investment
of funds in such accounts) will be owned by the Lower-Tier REMIC; the Excess Interest Distribution Account (and any portion of
the Collection Account holding Excess Interest) (including interest, if any, earned on the investment of funds in such accounts)
will be owned by the Grantor Trust for the benefit of the Holders of the Class V1-Z, Class V2-Z and Z Certificates; the Regular
Interest Distribution Account will be owned by the Grantor Trust for the benefit of the Holders of the related Classes of Certificates,
the Companion Distribution Account (including interest, if any, earned on the investment of funds in such account) will be owned
by the Companion Holders, as applicable; and the Upper-Tier REMIC Distribution Account (including interest, if any, earned on

(c)       Prior
to any Determination Date for the first Collection Period during which Excess Interest is received on any Mortgage Loan, and upon
notification from the Master Servicer or Special Servicer pursuant to Section 3.02(d), the Certificate Administrator, on
behalf of the Certificateholders, shall establish and maintain the Excess Interest Distribution Account in its own name on behalf
of the Trustee in trust for the benefit of the Holders of the Class V1-Z, Class V2-Z and Class Z Certificates. The Excess Interest
Distribution Account shall be established and maintained as an Eligible Account (or as a subaccount of an Eligible Account). Prior
to the applicable Distribution Date, the Master Servicer shall remit to the Certificate Administrator for deposit in the Excess
Interest Distribution Account an amount equal to the Excess Interest received prior to the Determination Date for the applicable
Collection Period.

 

(d)       Following
the distribution of the applicable portions of Excess Interest to Holders of the Class V1-Z, Class V2-Z and Class Z Certificates,
as applicable, on the first Distribution Date after which there are no longer any Mortgage Loans outstanding which pursuant to
their terms could pay Excess Interest, the Certificate Administrator shall terminate the Excess Interest Distribution Account.

 

(e)       The
Certificate Administrator shall establish (upon notice from the Special Servicer of an event occurring that generates Gain-on-Sale
Proceeds) and maintain the Gain-on-Sale Reserve Account for the benefit of the Certificateholders. The Gain-on-Sale Reserve Account
shall be maintained as an Eligible Account (or as a subaccount of an Eligible Account), separate and apart from trust funds for
mortgage pass-through certificates of other series administered by the Certificate Administrator.

 

Upon
the disposition of any REO Property, in accordance with Section 3.09 or Section 3.16, the Special Servicer will
calculate the Gain-on-Sale Proceeds, if any, realized that are allocable to the Mortgage Loan, as applicable, in connection with
such sale and, with respect to the Mortgage Loans, remit such funds to the Certificate Administrator for deposit into the Gain-on-Sale
Reserve Account. Any gain on such disposition that is allocable to any other related Companion Loan in accordance with the terms
of the related Intercreditor Agreement shall be remitted to the Companion Paying Agent for deposit into the Companion Distribution
Account.

 

(f)       Any
Non-Serviced Gain-on-Sale Proceeds received with respect to any Non-Serviced Mortgage Loan pursuant to the related Non-Serviced
PSA shall be remitted to the Certificate Administrator for deposit into the Gain-on-Sale Reserve Account.

 

(g)      [Reserved].

 

(h)      [Reserved]

 

(i)        If
any Loss of Value Payments are received in connection with a Material Defect pursuant to or as contemplated by Section 3.05(g)
of this Agreement, the Special Servicer shall establish and maintain one or more non-interest bearing accounts (collectively,
the “Loss of Value Reserve Fund”) to be held for the benefit of the Certificateholders, for purposes of holding
such Loss of Value Payments. Each account that constitutes the Loss of Value Reserve Fund shall be an Eligible Account or a sub-account
of an Eligible Account. The Special Servicer shall,

 

    -200-

     

    

 

upon
receipt, deposit in the Loss of Value Reserve Fund all Loss of Value Payments received by it. The Certificate Administrator shall,
based upon information obtained from the CREFC® reports delivered by the Master Servicer pursuant to the terms
hereof, account for the Loss of Value Reserve Fund as an outside reserve fund within the meaning of Treasury Regulations Section
1.860G-2(h) and not an asset of any Trust REMIC or the Grantor Trust. Furthermore, for all federal tax purposes, the Certificate
Administrator shall (i) treat amounts paid out of the Loss of Value Reserve Fund through the Collection Account to the Certificateholders
as contributed to and distributed by the Trust REMICs and (ii) treat any amounts paid out of the Loss of Value Reserve Fund through
the Collection Account to a Mortgage Loan Seller as distributions by the Trust to such Mortgage Loan Seller as beneficial owner
of the Loss of Value Reserve Fund. The applicable Mortgage Loan Seller will be the beneficial owner of the Loss of Value Reserve
Fund for all federal income tax purposes, and shall be taxable on all income earned thereon.

Account maintained by or for it, the Special Servicer) may direct any depository institution maintaining the Collection Account,
the Companion Distribution Account, or any Servicing Account (for purposes of this Section 3.06, an “Investment
Account”), the Special Servicer may direct any depository institution maintaining the REO Account or Loss of Value Reserve
Fund (also for purposes of this Section 3.06, an “Investment Account”) to invest or if it is such depository
institution, may itself invest, the funds held therein, only in one or more Permitted Investments bearing interest or sold at
a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the next succeeding
date on which funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the depository
institution maintaining such account is the obligor thereon and (ii) no later than the date on which funds are required to be
withdrawn from such account pursuant to this Agreement, if the depository institution maintaining such account is the obligor

shall be held in the name of the Master Servicer or the Special Servicer, as applicable, on behalf of the Trustee (in its capacity
as such) for the benefit of the Certificateholders. The Master Servicer (in the case of the Collection Account, the Companion
Distribution Account or any Servicing Account maintained by or for the Master Servicer), the Special Servicer (in the case of
the REO Account, Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) on behalf of the
Trustee, shall maintain continuous physical possession of any Permitted Investment of amounts in the Collection Account, the Companion
Distribution Account, the Servicing Accounts, the Loss of Value Reserve Fund or the REO Account, as applicable, that is either
(i) a “certificated security,” as such term is defined in the UCC (such that the Trustee shall have control pursuant
to Section 8-106 of the UCC) or (ii) other property in which a secured party may perfect its security interest by physical possession

or cause to be taken such action as the Trustee deems reasonably necessary to cause the Trustee to have control over such security
entitlement. In the event amounts on deposit in an Investment Account are at any time invested in a Permitted Investment payable
on demand, the Master Servicer (in the case of the Collection Account, the Companion Distribution Account or any Servicing Account
maintained by or for the Master Servicer) or the Special Servicer (in the case of the REO Account or any Servicing Account maintained
by or for the Special Servicer) shall:

with any notice required to be given thereunder, demand that payment thereon be made on the last day such Permitted Investment
may otherwise mature hereunder in an amount equal to the lesser of (a) all amounts then payable thereunder and (b) the amount
required to be withdrawn on such date; and

 

(ii)       demand
payment of all amounts due thereunder promptly upon determination by the Master Servicer, the Special Servicer, the Certificate
Administrator

(b)       Interest
and investment income realized on funds deposited in the Collection Account, the Companion Distribution Account or any Servicing
Account maintained by or for the Master Servicer to the extent of the Net Investment Earnings, if any, with respect to such account

Accounts) not required to be paid to the related Mortgagor and shall be subject to its withdrawal, or withdrawal at its direction,
in accordance with Section 3.03 or Section 3.05(a), as the case may be. Interest and investment income realized

Date to and including the immediately succeeding P&I Advance Date, shall be for the sole and exclusive benefit of the Special
Servicer and shall be subject to its withdrawal in accordance with Section 3.14(c). In the event that any loss shall be
incurred in respect of any Permitted Investment (as to which the Master Servicer or the Special Servicer, as applicable, would
have been entitled to any Net Investment Earnings hereunder) directed to be made by the Master Servicer or the Special Servicer,
as applicable, and on deposit in any of the Collection Account, the Companion Distribution Account, the Servicing Account, Loss
of Value Reserve Fund or the REO Account, the Master Servicer (in the case of the Collection Account, the Companion Distribution
Account or any Servicing Account maintained by or for the Master Servicer), the Special Servicer (in the case of the REO Account,
Loss of Value Reserve Fund or any Servicing Account maintained by or for the Special Servicer) shall deposit therein, no later
than the P&I Advance Date, without right of reimbursement, the amount of Net Investment Loss, if any, with respect to such
account for the period from and including the prior Distribution Date to and including the P&I Advance Date related to the
current Distribution Date; provided that neither the Master Servicer nor the Special Servicer shall be required to deposit
any loss on an investment of funds in an Investment Account if such loss is incurred solely as a result of the insolvency of the
federal or state chartered depository institution or trust company that holds such Investment Account, so long as such depository
institution or trust company satisfied the qualifications set forth in the definition of Eligible Account at the time such investment
was made (and, with respect to the Master Servicer or the Special Servicer, such federal or state chartered depository institution
or trust company is not an Affiliate of the Master Servicer or the Special Servicer, as applicable, unless such depository institution
or trust company satisfied the qualification set forth in the definition of Eligible Account both (x) at the time the investment
was made and (y) thirty (30) days prior to such insolvency).

 

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

Section
3.07 Maintenance of Insurance Policies; Errors and Omissions and Fidelity Coverage. (a) To the extent permitted by the
related Mortgage Loan documents and required by the Servicing Standard, the Master Servicer (with respect to the Mortgage Loans
(other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan) shall use efforts consistent with the Servicing
Standard to cause the Mortgagor to maintain (other than with respect to a Non-Serviced Mortgage Loan), and the Special Servicer
(with respect to REO Properties other than any Non-Serviced Mortgaged Properties) shall maintain all insurance coverage as is
required under the related Mortgage Loan documents except to the extent that the failure of the related Mortgagor to do so is
an Acceptable Insurance Default (and except as provided in the next sentence with respect to the Master Servicer or the Special
Servicer, as applicable). If the Mortgagor does not so maintain such insurance coverage, subject to its recoverability determination
with respect to any required Servicing Advance, the Master Servicer (with respect to the Mortgage Loans (other than a Non-Serviced
Mortgage Loan) and any related Serviced Companion Loan) or the Special Servicer (with respect to REO Properties other than a Non-Serviced
Mortgaged Property) shall maintain all insurance coverage as is required under, and such insurance coverage is to be obtained
from an insurer meeting the requirements under, the related Mortgage Loan documents, but only in the event the Trustee has an
insurable interest therein and such insurance is available to the Master Servicer or the Special Servicer and, if available, can
be obtained at commercially reasonable rates. Any determination that such insurance coverage is not available or not available
at commercially reasonable rates shall be made with the consent of the Directing Holder (prior to the occurrence and continuance
of any Control Termination Event) and, after consultation by the Special Servicer with the Risk Retention Consultation Party pursuant
to Section 6.08(a) (in the case of the Directing Holder and Risk Retention Consultation Party, other than with respect
to any Excluded Loan as to such party). Such determination shall be made by the Master Servicer (with respect to the Mortgage
Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan) or the Special Servicer (with respect
to REO Properties other than any Non-Serviced Mortgaged Property) except to the extent that the failure of the related Mortgagor
to do so is an Acceptable Insurance Default as determined by the Special Servicer; provided, however, that if any
Mortgage permits the holder thereof to dictate to the Mortgagor the insurance coverage to be maintained on such Mortgaged Property,
the Master Servicer or, with respect to an REO Property, the Special Servicer, as applicable, shall impose or maintain, as applicable,
such insurance requirements as are consistent with the Servicing Standard taking into account the insurance in place at the closing
of the Mortgage Loan, provided that if any Mortgage Loan documents permit the holder thereof to dictate to the Mortgagor
the insurance coverage to be maintained on such Mortgaged Property, the Master Servicer or, with respect to a REO Property, the
Special Servicer will impose or maintain such insurance requirements as are consistent with the Servicing Standard taking into
account the insurance in place at the origination of the Mortgage Loan; provided, further, that, with respect to
the immediately preceding proviso, the Master Servicer shall be obligated to use efforts consistent with the Servicing Standard
to cause the Mortgagor to maintain (or to itself maintain) insurance against property damage resulting from terrorist or similar
acts unless the Mortgagor’s failure is an Acceptable Insurance Default (as determined by the Special Servicer with the consent
of the Directing Holder (unless a Control Termination Event has occurred) and after consultation by the Special Servicer with
the Risk Retention Consultation Party pursuant to Section 6.08(a) (in each case, other than with respect to any Excluded
Loan as to such party) and only in the event the Trustee has an insurable interest

therein
and such insurance is available to the Master Servicer or the Special Servicer, as the case may be, and, if available, can be
obtained at commercially reasonable rates. The Master Servicer and the Special Servicer shall be entitled to rely on insurance
consultants (at the applicable servicer’s expense) in determining whether any insurance is available at commercially reasonable
rates. Subject to Section 3.15(a) and the costs of such insurance being reimbursed or paid to the Special Servicer as provided
in the third-to-last sentence of this paragraph, the Special Servicer shall maintain (except to the extent that the failure to
maintain such insurance coverage is an Acceptable Insurance Default) for each REO Property (other than any Non-Serviced Mortgaged
Property) no less insurance coverage than was previously required of the Mortgagor under the related Mortgage Loan documents unless
the Special Servicer determines with the consent of the Directing Holder (prior to the occurrence and continuance of a Control
Termination Event) and after consultation by the Special Servicer with the Risk Retention Consultation Party pursuant to Section
6.08(a) (in each case, other than with respect to a Mortgage Loan that is an Excluded Loan as to such party) that such insurance
is not available at commercially reasonable rates or that the Trustee does not have an insurable interest, in which case the Master
Servicer shall be entitled to conclusively rely on the Special Servicer’s determination. All Insurance Policies maintained
by the Master Servicer or the Special Servicer shall (i) contain a “standard” mortgagee clause, with loss payable
to the Master Servicer on behalf of the Trustee (in the case of insurance maintained in respect of Mortgage Loans (other than
any Non-Serviced Mortgage Loan), including any related Serviced Companion Loan, other than REO Properties) or to the Special Servicer
on behalf of the Trustee (in the case of insurance maintained in respect of REO Properties), (ii) be in the name of the Trustee
(in the case of insurance maintained in respect of REO Properties), (iii) include coverage in an amount not less than the lesser
of (x) the full replacement cost of the improvements securing Mortgaged Property or the REO Property, as applicable, and (y) the
outstanding principal balance owing on the related Mortgage Loan (including any related Serviced Companion Loan) or REO Loan,
as applicable, and in any event, the amount necessary to avoid the operation of any co-insurance provisions, (iv) include a replacement
cost endorsement providing no deduction for depreciation (unless such endorsement is not permitted under the related Mortgage
Loan documents), (v) be noncancelable without thirty (30) days prior written notice to the insured party (except in the case of
nonpayment, in which case such policy shall not be cancelled without ten (10) days prior notice) and (vi) subject to the first
proviso in the second sentence of this Section 3.07(a), be issued by a Qualified Insurer authorized under applicable law
to issue such Insurance Policies. Any amounts collected by the Master Servicer or the Special Servicer under any such Insurance
Policies (other than amounts to be applied to the restoration or repair of the related Mortgaged Property or REO Property or amounts
to be released to the related Mortgagor, in each case in accordance with the Servicing Standard and the provisions of the related
Mortgage Loan documents) shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.05(a).
Any costs incurred by the Master Servicer in maintaining any such Insurance Policies in respect of Mortgage Loans (including any
related Serviced Companion Loan) (other than REO Properties and other than any Non-Serviced Mortgage Loan) (i) if the Mortgagor
defaults on its obligation to do so, shall be advanced by the Master Servicer as a Servicing Advance (so long as such Advance
would not be a Nonrecoverable Advance and if such Advance would be a Nonrecoverable Advance then such cost shall instead be paid
out of the Collection Account) and will be charged to the related Mortgagor and (ii) shall not, for purposes of calculating monthly
distributions to Certificateholders, be added to the unpaid principal

 

    -215-

     

    

 

balance
of the related Mortgage Loan and Serviced Companion Loan (if any), notwithstanding that the terms of such Mortgage Loan or Serviced
Companion Loan so permit. Any cost incurred by the Special Servicer in maintaining any such Insurance Policies with respect to
REO Properties shall be an expense of the Trust payable out of the related REO Account pursuant to Section 3.14(c) or,
if the amount on deposit therein is insufficient therefor, advanced by the Master Servicer as a Servicing Advance (so long as
such Advance would not be a Nonrecoverable Advance and if such Advance would be a Nonrecoverable Advance then such cost shall
instead be paid out of the Collection Account). The foregoing provisions of this Section 3.07 shall apply to any Serviced
Whole Loan as if it were a single “Mortgage Loan”. Notwithstanding any provision to the contrary, the Master Servicer
shall not be required to maintain, and shall not be in default for failing to obtain, any earthquake or environmental insurance
on any Mortgaged Property unless such insurance was required at the time of origination of the related Mortgage Loan and is currently
available at commercially reasonable rates.

 

Notwithstanding
the foregoing, with respect to the Mortgage Loans (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion
Loan that either (x) require the Mortgagor to maintain “all risk” property insurance (and do not expressly permit
an exclusion for terrorism) or (y) contain provisions generally requiring the applicable Mortgagor to maintain insurance in types
and against such risks as the holder of such Mortgage Loan (including any related Serviced Companion Loan) reasonably requires
from time to time in order to protect its interests, the Master Servicer shall be consistent with the Servicing Standard, (A)
monitor in accordance with the Servicing Standard whether the insurance policies for the related Mortgaged Property contain Additional
Exclusions (provided that the Master Servicer will be entitled to conclusively rely upon the certificates of insurance
in determining whether such policies contain Additional Exclusions) (provided that the Master Servicer shall be entitled
to conclusively rely upon the certificates of insurance in determining whether such policies contain Additional Exclusions), (B)
request the Mortgagor to either purchase insurance against the risks specified in the Additional Exclusions or provide an explanation
as to its reasons for failing to purchase such insurance and (C) notify the Special Servicer if it has knowledge that any insurance
policy contains Additional Exclusions or if it has knowledge (such knowledge to be based upon the Master Servicer’s compliance
with the immediately preceding clauses (A) and (B) above) that any Mortgagor fails to purchase the insurance requested
to be purchased by the Master Servicer pursuant to clause (B) above. If the Special Servicer determines in accordance with
the Servicing Standard that such failure is not an Acceptable Insurance Default, the Special Servicer shall notify the Master
Servicer and the Master Servicer shall use efforts consistent with the Servicing Standard to cause such insurance to be maintained.
The Special Servicer (at the expense of the Trust) shall be entitled to rely on insurance consultants in making such determinations.
The Master Servicer shall be entitled to rely on insurance consultants (at the expense of such Master Servicer) in determining
whether Additional Exclusions exist. Furthermore, the Special Servicer shall promptly deliver such conclusions in writing to the
17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website for those Mortgage Loans that (i) have
one of the ten (10) highest outstanding Stated Principal Balances of all of the Mortgage Loans then included in the Trust or (ii)
comprise more than 5% of the outstanding Stated Principal Balance of the Mortgage Loans then included in the Trust. During the
period that the Special Servicer is evaluating the availability of such insurance or waiting for a response from the Directing
Holder, or with respect to a Serviced AB Whole Loan, the holder

 

    -216-

     

    

 

of
the related Subordinate Companion Loan, or to consult with the Risk Retention Consultation Party pursuant to Section 6.08(a),
neither the Master Servicer nor the Special Servicer will be liable for any loss related to its failure to require the Mortgagor
to maintain (or its failure to maintain) such insurance and shall not be in default of its obligations as a result of such failure
unless the Master Servicer or the Special Servicer is required to take any immediate action pursuant to the Servicing Standard
or other servicing requirements of this Agreement and the Master Servicer will not itself maintain such insurance or cause such
insurance to be maintained.

 

(b)       (i)
If the Master Servicer or the Special Servicer shall obtain and maintain a blanket Insurance Policy with a Qualified Insurer insuring
against fire and hazard losses on all of the Mortgage Loans (including any related Serviced Companion Loan, but excluding any
Non-Serviced Mortgage Loan) or REO Properties (other than with respect to a Non-Serviced Mortgaged Property), as the case may
be, required to be serviced and administered hereunder, then, to the extent such Insurance Policy provides protection equivalent
to the individual policies otherwise required, the Master Servicer or the Special Servicer shall conclusively be deemed to have
satisfied its obligation to cause fire and hazard insurance to be maintained on the related Mortgaged Properties or REO Properties.
Such Insurance Policy may contain a deductible clause, in which case the Master Servicer or the Special Servicer shall, if there
shall not have been maintained on the related Mortgaged Property or REO Property a fire and hazard Insurance Policy complying
with the requirements of Section 3.07(a), and there shall have been one or more losses which would have been covered by
such Insurance Policy, promptly deposit into the Collection Account from its own funds the amount of such loss or losses that
would have been covered under the individual policy but are not covered under the blanket Insurance Policy because of such deductible
clause to the extent that any such deductible exceeds the deductible limitation that pertained to the related Mortgage Loan (including
any related Serviced Companion Loan), or in the absence of such deductible limitation, the deductible limitation which is consistent
with the Servicing Standard. In connection with its activities as administrator and Master Servicer of the Mortgage Loans or any
Serviced Companion Loans, the Master Servicer agrees to prepare and present, on behalf of itself, the Trustee and Certificateholders,
claims under any such blanket Insurance Policy in a timely fashion in accordance with the terms of such policy. Consistent with
subsection (a) above, the Special Servicer, to the extent consistent with the Servicing Standard, may maintain, earthquake
insurance on REO Properties (other than with respect to a Non-Serviced Mortgaged Property), provided coverage is available at
commercially reasonable rates, the cost of which shall be a Servicing Advance.

 

(ii)     If
the Master Servicer or the Special Servicer shall cause any Mortgaged Property or REO Property to be covered by a master single
interest or force-placed insurance policy with a Qualified Insurer naming the Master Servicer or the Special Servicer on behalf
of the Trustee as the loss payee, then to the extent such Insurance Policy provides protection equivalent to the individual policies
otherwise required, the Master Servicer or the Special Servicer shall conclusively be deemed to have satisfied its obligation
to cause such insurance to be maintained on the related Mortgaged Properties and REO Properties. In the event the Master Servicer
or the Special Servicer shall cause any Mortgaged Property or REO Property to be covered by such master single interest or force-placed
insurance policy, the incremental costs of such insurance applicable to such Mortgaged Property or REO Property (i.e., other than
any minimum or standby premium payable for such policy whether or not any Mortgaged Property or REO Property is

 

    -217-

     

    

 

covered
thereby) shall be paid by the Master Servicer as a Servicing Advance. Such master single interest or force-placed policy may contain
a deductible clause, in which case the Master Servicer or the Special Servicer shall, in the event that there shall not have been
maintained on the related Mortgaged Property or REO Property a policy otherwise complying with the provisions of Section 3.07(a),
and there shall have been one or more losses which would have been covered by such policy had it been maintained, deposit into
the Collection Account from its own funds the amount not otherwise payable under the master single or force-placed interest policy
because of such deductible clause, to the extent that any such deductible exceeds the deductible limitation that pertained to
the related Mortgage Loan, including any related Serviced Companion Loan, or, in the absence of any such deductible limitation,
the deductible limitation which is consistent with the Servicing Standard.

 

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

 

(d)       At
the time the Master Servicer determines in accordance with the Servicing Standard that any Mortgaged Property (other than a Non-Serviced
Mortgaged Property) is in a federally designated special flood hazard area (and such flood insurance has been made available),
the Master Servicer will use efforts consistent with the Servicing Standard to cause the related Mortgagor (in accordance with
applicable law and the terms of the Mortgage Loan and related Serviced Companion Loan documents) to maintain, and, if the related
Mortgagor shall default in its obligation to so maintain, shall itself maintain to the extent available at commercially reasonable
rates (as determined by the Master Servicer in accordance with the Servicing Standard) and to the extent the Trustee, as mortgagee,
has an insurable interest therein, flood insurance in respect thereof. Such flood insurance shall be in an amount equal to the
lesser of (i) the unpaid principal balance of the related Mortgage Loan (and any related Serviced Companion Loan, if applicable),
and (ii) the maximum amount of insurance which is available under the National Flood Insurance Act of 1968, as amended, plus such

 

    -218-

     

    

 

additional
excess flood coverage with respect to the Mortgaged Property, if any, in an amount consistent with the Servicing Standard, but
only to the extent the related Mortgage Loan (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan permits
the mortgagee to require such coverage and the maintenance of such coverage is consistent with the Servicing Standard. If the
cost of any insurance described above is not borne by the Mortgagor, the Master Servicer shall promptly make a Servicing Advance
for such costs.

 

(e)       During
all such times as any REO Property (other than with respect to a Non Serviced Mortgaged Property) shall be located in a federally
designated special flood hazard area, the Special Servicer will cause to be maintained, to the extent available at commercially
reasonable rates (as determined by the Special Servicer (with the consent of the Directing Holder (prior to the occurrence and
continuance of a Control Termination Event) and in consultation with the Risk Retention Consultation Party pursuant to Section
6.08(a) (in either such case, other than with respect to any Mortgage Loan that is an Excluded Loan as to such party)) in
accordance with the Servicing Standard), a flood insurance policy meeting the requirements of the current guidelines of the Federal
Insurance Administration in an amount representing coverage not less than the maximum amount of insurance which is available under
the National Flood Insurance Act of 1968, as amended. The cost of any such flood insurance with respect to an REO Property shall
be an expense of the Trust payable out of the related REO Account pursuant to Section 3.14(c) or, if the amount on deposit
therein is insufficient therefor, paid by the Master Servicer as a Servicing Advance.

 

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

 

Section
3.08 Enforcement of Due-on-Sale Clauses; Assumption Agreements. (a)
As to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan that contains a provision
in the nature of a “due-on-sale” clause, which by its terms:

 

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

 

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

 

then,
for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement, the Special Servicer
(or, with respect to non-Specially Serviced Loans, if mutually agreed to by the Master Servicer and the Special Servicer, the
Master Servicer (in a manner consistent with the Servicing Standard and subject to the consent of the Special Servicer)), on behalf
of the Trustee as the mortgagee of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or related
Companion Loan (x) to

 

    -219-

     

    

 

accelerate
the payments thereon or (y) to withhold its consent to any sale or transfer, consistent with the Servicing Standard or (b) waive
any right to exercise such rights, provided that, (i)(A) if such Mortgage Loan is not an Excluded Loan and no Control Termination
Event shall have occurred and be continuing, the Master Servicer or the Special Servicer, as the case may be, shall obtain the
prior written consent of (x) in the case of the Master Servicer, the Special Servicer and (y) in the case of the Special Servicer,
the Directing Holder, and the Directing Holder’s consent shall be deemed given ten (10) Business Days after receipt (unless
earlier objected to by the Directing Holder) of the Special Servicer’s written analysis and recommendation with respect
to such waiver together with such other information reasonably requested by the Directing Holder and (B) if such Mortgage Loan
is not an Excluded Loan, a Control Termination Event shall have occurred and be continuing and no Consultation Termination Event
shall have occurred and be continuing, the Special Servicer shall consult with the Directing Holder and the Risk Retention Consultation
Party pursuant to Section 6.08(a) hereof and (ii) with respect to any Mortgage Loan (x) with a Stated Principal Balance
greater than $35,000,000, (y) with a Stated Principal Balance greater than or equal to 5% of the aggregated Stated Principal Balance
of the Mortgage Loans then outstanding or (z) together with all other Mortgage Loans with which it is cross-collateralized or
cross-defaulted or together with all other Mortgage Loans with the same Mortgagor (or an affiliate thereof), that is one of the
ten largest Mortgage Loans outstanding (by Stated Principal Balance), the Master Servicer or the Special Servicer, as the case
may be, prior to consenting to any action, shall obtain, a Rating Agency Confirmation from each Rating Agency and a confirmation
of any applicable rating agency that such action will not result in the downgrade, withdrawal or qualification of its then current
ratings of any class of Serviced Companion Loan Securities (if any) (provided that such rating agency confirmation may
be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
pursuant to Section 3.25), provided, however, that with respect to subclauses (x) and (y) of
this subclause (iii), such Mortgage Loan shall also have a Stated Principal Balance of at least $10,000,000 for such Rating
Agency Confirmation requirement to apply. Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with
respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of
the Controlling Class (regardless of whether an Operating Advisor Consultation Event has occurred and is continuing), the Special
Servicer shall consult with the Operating Advisor (telephonically or electronically), on a non-binding basis, in connection with
the related transactions involving proposed Major Decisions that it is processing or for which its consent is required and consider
alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section
6.08 for consulting with the Operating Advisor.

 

In
connection with any request for a Rating Agency Confirmation from a Rating Agency (or, with respect to any Serviced Companion
Loan Securities, the related rating agencies) pursuant to this Section 3.08(a), the Special Servicer shall (if not already
provided in accordance with Section 3.25 of this Agreement) deliver a Review Package to the 17g-5 Information Provider
(or, with respect to any Serviced Companion Loan Securities, the related 17g-5 information provider) in accordance with Section
3.25 of this Agreement.

 

If
any Mortgage Loan (other than a Non-Serviced Mortgage Loan) or related Serviced Companion Loan provides that such Mortgage Loan
or related Serviced Companion Loan may be assumed or transferred without the consent of the mortgagee provided that certain

 

    -220-

     

    

 

conditions
are satisfied, then for so long as such Mortgage Loan or related Serviced Companion Loan is being serviced under this Agreement,
the Special Servicer, with respect to all Specially Serviced Loans (other than a Non-Serviced Mortgage Loan) or related Serviced
Companion Loans, on behalf of the Trustee as the mortgagee of record, shall determine in accordance with the Servicing Standard
whether such conditions have been satisfied, or, with respect to any Mortgage Loan which does not allow the mortgagee discretion
in approving a transfer or assumption or does not allow for discretion in determining whether conditions to a transfer or assumption
have been satisfied, the Master Servicer, on behalf of the Trustee as mortgagee of record, shall make such determination with
respect to whether such conditions have been satisfied.

 

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

 

(i)       provides
that such Mortgage Loan and any related Companion Loan shall (or may at the mortgagee’s option) become due and payable upon
the creation of any additional lien or other encumbrance on the related Mortgaged Property or equity interests in the Mortgagor
or principals of the Mortgagor; or

 

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

 

then,
for so long as such Mortgage Loan (and related Companion Loan, if applicable) is serviced under this Agreement, the Special Servicer
(or, with respect to non-Specially Serviced Loans, if mutually agreed to by the Master Servicer and the Special Servicer, the
Master Servicer (in a manner consistent with the Servicing Standard and subject to the consent of the Special Servicer), on behalf
of the Trustee as the mortgagee of record, shall (a) exercise any right it may have with respect to such Mortgage Loan or related
Companion Loan (x) to accelerate the payments thereon or (y) to withhold its consent to the creation of any additional lien or
other encumbrance, consistent with the Servicing Standard or (b) waive its right to exercise such rights, provided that
(i)(A) if such Mortgage Loan is not an Excluded Loan and no Control Termination Event shall have occurred and be continuing, the
Master Servicer or the Special Servicer, as the case may be, shall obtain the prior written consent of (x) in the case of the
Master Servicer, the Special Servicer and (y) in the case of the Special Servicer, the Directing Holder, and the Directing Holder’s
consent shall be deemed given ten (10) Business Days after receipt (unless earlier objected to by the Directing Holder) of the
Special Servicer’s written analysis and recommendation with respect to such waiver together with such other information
reasonably required by the Directing Holder and (B) if such Mortgage Loan is not an Excluded Loan, a Control Termination Event
shall have occurred and be continuing, and no Consultation Termination Event shall have occurred and be continuing, the Special
Servicer shall consult with the Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08(a)
hereof and (ii) the Special Servicer or the Master Servicer, as applicable, has obtained Rating Agency Confirmation from each
Rating Agency and a confirmation of any applicable rating agency that such action will not result in the downgrade, withdrawal
or qualification of its then current ratings of any class of Serviced Companion Loan Securities (if any) (provided that

 

    -221-

     

    

 

such
rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25) if such Mortgage Loan (A) has an outstanding principal
balance that is greater than or equal to 2% of the Stated Principal Balance of the outstanding Mortgage Loans, (B) has an LTV
Ratio greater than 85% (including any existing and proposed debt), (C) has a Debt Service Coverage Ratio less than 1.20x (in each
case, determined based upon the aggregate of the Stated Principal Balance of the Mortgage Loan and related Companion Loan, if
any, and the principal amount of the proposed additional lien) (D) is one of the ten largest Mortgage Loans (by Stated Principal
Balance) or (E) has a Stated Principal Balance greater than $20,000,000; provided, however, that with respect to
subclauses (A), (B), (C) and (D) of this subclause (iii), such Mortgage Loan shall also have
a Stated Principal Balance of at least $10,000,000 for such Rating Agency Confirmation requirement to apply. Notwithstanding anything
herein to the contrary, with respect to any Excluded Loan (regardless of whether an Operating Advisor Consultation Event has occurred
and is continuing), the Special Servicer shall consult with the Operating Advisor (telephonically or electronically), on a non-binding
basis, in connection with the related transactions involving proposed Major Decisions and consider alternative actions recommended
by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting
with the Operating Advisor.

 

In
connection with any request for a Rating Agency Confirmation from a Rating Agency (or, with respect to any Serviced Companion
Loan Securities, the related rating agencies) pursuant to this Section 3.08(b), the Special Servicer shall (if not already
provided in accordance with Section 3.25 of this Agreement) deliver a Review Package to the 17g-5 Information Provider
(or, with respect to any Serviced Companion Loan Securities, the related 17g-5 information provider) in accordance with Section
3.25 of this Agreement.

 

To
the extent permitted by the related Mortgage Loan documents, the Rating Agency Confirmation described in the immediately preceding
paragraph or in Section 3.08(a) shall be an expense of the related Mortgagor; provided that if the Mortgage Loan
documents are silent as to who bears the costs of obtaining any such Rating Agency Confirmation, the Special Servicer shall use
reasonable efforts to make the related Mortgagor bear such costs and expenses. Unless determined to be a Nonrecoverable Advance
such costs not collected from the related Mortgagor shall be advanced as a Servicing Advance.

 

If
any Mortgage Loan or related Companion Loan provides that such Mortgage Loan or related Companion Loan may be further encumbered
without the consent of the mortgagee provided that certain conditions are satisfied and there is no lender discretion with
respect to the satisfaction of such conditions, then for so long as such Mortgage Loan or related Companion Loan is being serviced
under this Agreement, the Special Servicer, with respect to all Mortgage Loans (other than a Non-Serviced Mortgage Loan), on behalf
of the Trustee as the mortgagee of record, shall determine whether such conditions have been satisfied.

 

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

 

    -222-

     

    

 

(d)       Except
as otherwise permitted by Section 3.08(a) and (b) and/or Section 3.18, neither the Master Servicer nor the
Special Servicer shall agree to modify, waive or amend any term of any Mortgage Loan and related Serviced Companion Loan, as applicable,
in connection with the taking of, or the failure to take, any action pursuant to this Section 3.08. The Master Servicer
and the Special Servicer, as applicable, shall provide copies of any final waivers (except with respect to provision of any such
waivers to the 17g-5 Information Provider, exclusive of any Privileged Information) it effects pursuant to Section 3.08(a)
or (b) to each other and to the 17g-5 Information Provider with respect to each Mortgage Loan, and shall notify the
Trustee, the Certificate Administrator, each other and, subject to the terms of this Agreement, the 17g-5 Information Provider
(for posting to the 17g-5 Information Provider’s Website in accordance with Section 3.25) and, with respect to a
Whole Loan, the related Serviced Companion Noteholder, of any assumption or substitution agreement executed pursuant to Section
3.08(a) or (b) and shall forward thereto a copy of such agreement.

 

(e)       Notwithstanding
any other provision of this Agreement, the Special Servicer may not waive its rights or grant its consent (or consent to the Master
Servicer taking any such action) under any “due-on-sale” or “due-on-encumbrance” clause relating to any
Mortgage Loan without ((i) prior to the occurrence and continuance of a Control Termination Event and (ii) other than with respect
to any Excluded Loan) the consent of the Directing Holder (or (i) after the occurrence and during the continuance of a Control
Termination Event and (ii) other than with respect to any Excluded Loan, but prior to a Consultation Termination Event, upon consultation
with the Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08 hereof). The Directing Holder
shall have ten (10) Business Days after receipt of notice along with the Master Servicer’s or Special Servicer’s recommendation
and analysis with respect to such proposed waiver or proposed granting of consent and any additional information the Directing
Holder may reasonably request from the Special Servicer of a proposed waiver or consent under any “due-on-sale” or
“due-on-encumbrance” clause in which to grant or withhold its consent (provided that if the Special Servicer
fails to receive a response to such notice from the Directing Holder in writing within such period, then the Directing Holder
shall be deemed to have consented to such proposed waiver or consent).

 

(f)       Notwithstanding
the foregoing provisions of this Section 3.08, if the Special Servicer makes a determination under Sections 3.08(a)
or 3.08(b) hereof that the applicable conditions in the related Mortgage Loan or Companion Loan documents, as applicable,
with respect to assumptions or encumbrances permitted without the consent of the mortgagee have been satisfied, the applicable
assumptions and transfers may be subject to an assumption or other fee, unless such fees are otherwise prohibited pursuant to
the Mortgage Loan documents; provided that any such fee not provided for in the Mortgage Loan documents does not constitute
a “significant” change in yield pursuant to Treasury Regulations Section 1.1001-3(e)(2).

 

(g)       Notwithstanding
any other provision of this Section 3.08, without any other approval or consent, the Master Servicer (for Mortgage Loans
and Serviced Whole Loans other than Specially Serviced Loans) may grant and process a Mortgagor’s request for (i) consent
to subject the related Mortgaged Property to an immaterial easement, a right of way or similar agreement for utilities, access,
parking, public improvements or another purpose, (ii) consent to subordination of the related Mortgage Loan or Serviced Whole
Loan to such easement, right of

 

    -223-

     

    

 

way
or similar agreement and (iii) consent to any other matter that is not a Major Decision or Special Servicer Decision; provided
that the Master Servicer (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 any Trust REMIC to fail to qualify as a REMIC at any time that any Certificates
are outstanding. The Master Servicer may rely on an Opinion of Counsel in making any such determination under clause (b) above.

 

Section
3.09 Realization Upon Defaulted Loans and Companion Loans. (a) Upon an event of default under the Mortgage Loan documents
related to a Serviced Whole Loan or a Mortgage Loan with mezzanine debt, the Master Servicer shall promptly provide written notice
to the related Companion Holder or mezzanine lender, as applicable, with a copy of such notice to the Special Servicer. The Special
Servicer shall, subject to subsections (b) through (d) of this Section 3.09 and Section 3.24, subject
to the Directing Holder’s and the Risk Retention Consultation Party’s respective rights pursuant to Section 6.08,
and any Companion Holder or mezzanine lender’s rights under the related Intercreditor Agreement (in the case of a Serviced
Whole Loan, on behalf of the holders of the beneficial interest of the related Companion Loan) or this Agreement, exercise reasonable
efforts, consistent with the Servicing Standard, to foreclose upon or otherwise comparably convert (which may include an REO Acquisition)
the ownership of property securing any such Mortgage Loan (other than any Non-Serviced Mortgage Loan) and related Companion Loan,
if any, as come into and continue in default as to which no satisfactory arrangements (including by way of a discounted pay-off)
can be made for collection of delinquent payments, and which are not released from the Trust Fund pursuant to any other provision
hereof. The foregoing is subject to the provision that, in any case in which a Mortgaged Property shall have suffered damage from
an Uninsured Cause, the Master Servicer or the Special Servicer shall not be required to make a Servicing Advance and expend funds
toward the restoration of such property unless the Special Servicer has determined in its reasonable discretion that such restoration
will increase the net proceeds of liquidation of such Mortgaged Property to Certificateholders after reimbursement to the Master
Servicer for such Servicing Advance, and the Master Servicer or the Special Servicer has not determined that such Servicing Advance
together with accrued and unpaid interest thereon would constitute a Nonrecoverable Advance. The costs and expenses incurred by
the Special Servicer in any such proceedings shall be advanced by the Master Servicer; provided that, in each case, such
cost or expense would not, if incurred, constitute a Nonrecoverable Servicing Advance. Nothing contained in this Section 3.09
shall be construed so as to require the Master Servicer or the Special Servicer, on behalf of the Trust, to make an offer
on any Mortgaged Property at a foreclosure sale or similar proceeding that is in excess of the fair market value of such property,
as determined by the Master Servicer or the Special Servicer in its reasonable judgment taking into account the factors described
in Section 3.16(b) and the results of any Appraisal obtained pursuant to the following sentence, all such offers to be
made in a manner consistent with the Servicing Standard. If and when the Special Servicer or the Master Servicer deems it necessary
and prudent for purposes of establishing the fair market value of any Mortgaged Property securing a Defaulted Loan or any related
defaulted Companion Loan, whether for purposes of making an offer at foreclosure or otherwise, the Special Servicer or the Master
Servicer, as the case may be, is authorized to have an Appraisal performed with respect to such property by an

 

    -224-

     

    

 

Independent
MAI-designated appraiser the cost of which shall be paid by the Master Servicer as a Servicing Advance.

 

(b)       The
Special Servicer shall not acquire any personal property pursuant to this Section 3.09 unless either:

 

(i)      such
personal property is incidental to real property (within the meaning of Section 856(e)(1) of the Code) so acquired by the Special
Servicer; or

 

(ii)     the
Special Servicer shall have obtained an Opinion of Counsel (the cost of which shall be paid by the Master Servicer as a Servicing
Advance) to the effect that the holding of such personal property by the Trust (to the extent not allocable to the related Companion
Loan) will not cause an Adverse REMIC Event.

 

(c)       Notwithstanding
the foregoing provisions of this Section 3.09 and Section 3.24, neither the Master Servicer nor the Special Servicer
shall, on behalf of the Trustee, obtain title to a Mortgaged Property in lieu of foreclosure or otherwise, or take any other action
with respect to any Mortgaged Property, if, as a result of any such action, the Trustee, on behalf of the Certificateholders and/or
any related Companion Holder, would be considered to hold title to, to be a “mortgagee-in-possession” of, or to be
an “owner” or “operator” of such Mortgaged Property within the meaning of CERCLA or any comparable law,
unless (as evidenced by an Officer’s Certificate to such effect delivered to the Trustee) the Special Servicer has previously
determined in accordance with the Servicing Standard, based on an Environmental Assessment of such Mortgaged Property performed
by an Independent Person who regularly conducts Environmental Assessments and performed within six (6) months prior to any such
acquisition of title or other action, that:

 

(i)       such
Mortgaged Property is in compliance with applicable environmental laws or, if not, after consultation with an environmental consultant,
that it would be in the best economic interest of the Certificateholders (and with respect to any Serviced Whole Loan, the related
Companion Holders), as a collective whole as if such Certificateholders and, if applicable, such Companion Holders constituted
a single lender, to take such actions as are necessary to bring such Mortgaged Property in compliance with such laws, and

 

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

 

    -225-

     

    

 

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

 

(d)       If
(i) the environmental testing contemplated by subsection (c) above establishes that either of the conditions set forth
in clauses (i) and (ii) of subsection (c) above of the first sentence thereof has not been satisfied with
respect to any Mortgaged Property securing a Defaulted Loan and, in the case of a Serviced Mortgage Loan, any related Companion
Loan, and (ii) there has been no breach of any of the representations and warranties set forth in or required to be made pursuant
to Section 6 of each of the Mortgage Loan Purchase Agreements for which the applicable Mortgage Loan Seller could be required
to repurchase such Defaulted Loan pursuant to Section 6 of the applicable Mortgage Loan Purchase Agreement, then the Special Servicer
shall take such action as it deems to be in the best economic interest of the Trust (other than proceeding to acquire title to
the Mortgaged Property) and is hereby authorized, with the consent of the Directing Holder and after consultation with the Risk
Retention Consultation Party pursuant to Section 6.08(a) (in each case, (A) prior to the occurrence and continuance of
a Control Termination Event (or with respect to any AB Mortgage Loan, after the occurrence and during the continuation of an AB
Control Appraisal Period, but prior to the occurrence and continuance of a Control Termination Event) and (B) other than with
respect to any Excluded Loan as to such party) at such time as it deems appropriate to release such Mortgaged Property from the
lien of the related Mortgage, provided that, if such Mortgage Loan has a then-outstanding principal balance of greater
than $1,000,000, then prior to the release of the related Mortgaged Property from the lien of the related Mortgage, (i) the Special
Servicer shall have notified the Rating Agencies, the Trustee, the Certificate Administrator, the Master Servicer, the Directing
Holder and the Risk Retention Consultation Party (in the case of the Directing Holder, prior to the occurrence and continuance
of a Consultation Termination Event, and in the case of the Directing Holder or the Risk Retention Consultation Party other than
with respect to any Excluded Loan as to such party), in writing of its intention to so release such Mortgaged Property and the
bases for such intention, (ii) the Certificate Administrator shall have posted

 

    -226-

     

    

 

such
notice of the Special Servicer’s intention to so release such Mortgaged Property to the Certificate Administrator’s
Website pursuant to Section 3.13(b) and (iii) in addition to the prior written consent of the Directing Holder as required
above, the Holders of Certificates entitled to a majority of the Voting Rights shall have consented or have been deemed to have
consented to such release within thirty (30) days of the Certificate Administrator’s posting such notice to the Certificate
Administrator’s Website (failure to respond by the end of such 30-day period being deemed consent of the Holders of the
Certificates). To the extent any fee charged by any Rating Agency in connection with rendering such written confirmation is not
paid by the related Mortgagor, such fee is to be an expense of the Trust; provided that the Special Servicer shall use
commercially reasonable efforts to collect such fee from the Mortgagor to the extent permitted under the related Mortgage Loan
documents.

 

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

 

(f)       The
Special Servicer shall notify the Master Servicer of any abandoned and/or foreclosed properties which require reporting to the
Internal Revenue Service and shall provide the Master Servicer with all information regarding forgiveness of indebtedness and
required to be reported with respect to any Mortgage Loan or related Companion Loan that is abandoned or foreclosed and the Master
Servicer shall report to the Internal Revenue Service and the related Mortgagor, in the manner required by applicable law, such
information and the Master Servicer shall report, via Form 1099A or Form 1099C (or any successor form), all forgiveness of indebtedness
and abandonment and foreclosure to the extent such information has been provided to the Master Servicer by the Special Servicer.
Upon request, the Master Servicer shall deliver a copy of any such report to the Trustee and the Certificate Administrator.

 

(g)       The
Special Servicer shall have the right to determine, in accordance with the Servicing Standard, the advisability of the maintenance
of an action to obtain a deficiency judgment if the state in which the Mortgaged Property is located and the terms of the Mortgage
Loan (and if applicable, the related Companion Loan) permit such an action.

 

(h)       The
Special Servicer shall maintain accurate records, prepared by one of its Servicing Officers, of each Final Recovery Determination
in respect of a Defaulted Loan (other than with respect to a Non-Serviced Mortgage Loan) or defaulted Companion Loan or any REO
Property (other than any Non-Serviced Mortgaged Property) and the basis thereof. Each Final Recovery Determination shall be evidenced
by an Officer’s Certificate promptly delivered to the Trustee, the Certificate Administrator, the Directing Holder and the
Risk Retention Consultation Party (but in the case of the Directing Holder and the Risk Retention Consultation

 

    -227-

     

    

 

Party,
other than with respect to any Excluded Loan as to such party) and the Master Servicer and in no event later than the next succeeding
P&I Advance Determination Date.

 

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

 

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

 

(c)       Within
three (3) Business Days (or within such shorter period as delivery can reasonably be accomplished if the Special Servicer notifies
the Trustee of an exigency) of receipt thereof, the Trustee shall execute and deliver to the Special Servicer any court pleadings,
requests for trustee’s sale or other documents necessary to the foreclosure or trustee’s sale in respect of a Mortgaged
Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note (including any note evidencing
a related Companion Loan) or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided
by the Mortgage Note or Mortgage or otherwise available at law or in equity. The Special Servicer shall be responsible for the
preparation of all such documents and pleadings. When

 

    -228-

     

    

 

submitted
to the Trustee for signature, such documents or pleadings shall be accompanied by a certificate of a Servicing Officer requesting
that such pleadings or documents be executed by the Trustee and certifying as to the reason such documents or pleadings are required
and that the execution and delivery thereof by the Trustee will not invalidate or otherwise affect the lien of the Mortgage, except
for the termination of such a lien upon completion of the foreclosure or trustee’s sale. The Trustee shall not be required
to review such documents for their sufficiency or enforceability.

 

(d)       If,
from time to time, pursuant to the terms of the applicable Non-Serviced Intercreditor Agreement and the applicable Non-Serviced
PSA, and as appropriate for enforcing the terms of a Non-Serviced Mortgage Loan, the applicable Non-Serviced Master Servicer requests
delivery to it of the original Mortgage Note for a Non-Serviced Mortgage Loan, then the Custodian shall release or cause the release
of such original Mortgage Note to such Non-Serviced Master Servicer or its designee.

 

Section
3.11 Servicing Compensation. (a) As compensation for its activities hereunder, the Master Servicer shall be entitled to
receive the Servicing Fee with respect to each Mortgage Loan, Serviced Companion Loan and REO Loan (other than the portion of
any REO Loan related to any Non-Serviced Companion Loan) (including Specially Serviced Loans and any Non-Serviced Mortgage Loan
constituting a “specially serviced loan” under any related Non-Serviced PSA). As to each Mortgage Loan, Companion
Loan and REO Loan, the Servicing Fee shall accrue from time to time at the Servicing Fee Rate and shall be computed on the basis
of the Stated Principal Balance of such Mortgage Loan, Companion Loan or REO Loan, as the case may be, and in the same manner
as interest is calculated on such Mortgage Loan, Companion Loan or REO Loan, as the case may be, and, in connection with any partial
month interest payment, for the same period respecting which any related interest payment due on such Mortgage Loan or Companion
Loan or deemed to be due on such REO Loan is computed. The Servicing Fee with respect to any Mortgage Loan, Companion Loan or
REO Loan shall cease to accrue if a Liquidation Event occurs with respect to the related Mortgage Loan, except that if such Mortgage
Loan is part of a Serviced Whole Loan and such Serviced Whole Loan continues to be serviced and administered under this Agreement
notwithstanding such Liquidation Event, then the applicable Servicing Fee shall continue to accrue and be payable as if such Liquidation
Event did not occur. The Servicing Fee shall be payable monthly, on a loan-by-loan basis, from payments of interest on each Mortgage
Loan, Companion Loan and REO Revenues allocable as interest on each REO Loan, and as otherwise provided by Section 3.05(a).
The Master Servicer shall be entitled to recover unpaid Servicing Fees in respect of any Mortgage Loan, Companion Loan or REO
Loan out of that portion of related payments, Insurance and Condemnation Proceeds, Liquidation Proceeds and REO Revenues (in the
case of an REO Loan) allocable as recoveries of interest, to the extent permitted by Section 3.05(a). Except as set forth
in the next two sentences, the third paragraph of this Section 3.11(a), Section 6.03, Section 6.05 and Section
7.01(c), the right to receive the Servicing Fee may not be transferred in whole or in part (except in connection with a transfer
of all of the Master Servicer’s duties and obligations hereunder to a successor servicer in accordance with the terms hereof).
With respect to each Serviced Pari Passu Companion Loan, the Servicing Fee shall be payable to the Master Servicer from amounts
payable in respect of such Serviced Pari Passu Companion Loan, subject to the terms of the related Intercreditor Agreement.

 

    -229-

     

    

 

The
Master Servicer shall be entitled to retain, and shall not be required to deposit in the Collection Account pursuant to Section
3.04(a), additional servicing compensation (other than with respect to a Non-Serviced Mortgage Loan) in the form of the following
amounts to the extent collected from the related Mortgagor: (i) 100% of Excess Modification Fees related to any modifications,
waivers, extensions or amendments of any Non-Specially Serviced Loans (including any related Serviced Companion Loans, to the
extent not prohibited by the related Intercreditor Agreement); provided that with respect to such transactions, the consent
of, and/or processing by, the Special Servicer is not required to take such action and, in the event that the Special Servicer’s
consent and/or processing is required, then the Master Servicer shall be entitled to 50% of such fees, (ii) 100% of all assumption
application fees and other similar fees received on any Mortgage Loans solely to the extent the Master Servicer is processing
the underlying transaction (including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor
Agreement) (whether or not the consent of the Special Servicer is required) and any fee actually paid by a Mortgagor in connection
with the defeasance of a Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any related Serviced Companion Loan (provided
that 50% of the portion of any fees payable solely in connection with any modification, waiver, amendment or consent executed
in connection with a defeasance transaction for which the consent, processing or approval of the Special Servicer is required
(and specifically excluding any defeasance fees), must be paid by the Master Servicer to the Special Servicer); (iii) 100% of
assumption, waiver, consent and earnout fees, and other similar fees (other than assumption application fees and defeasance fees)
pursuant to Section 3.08 and Section 3.18 or other actions performed in connection with this Agreement on the Non
Specially Serviced Loans (including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor
Agreement), provided that the consent, processing or approval of the Special Servicer is not required to take such actions, (iv)
50% of all assumption, waiver, consent and earnout fees, and other similar fees (other than assumption application and defeasance
fees), pursuant to Section 3.08 and Section 3.18 on any Non Specially Serviced Loan (including any related Serviced
Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) for which the Special Servicer’s processing,
consent or approval is required and only to the extent that all amounts then due and payable with respect to the related Mortgage
Loan have been paid, (v) 100% of charges by the Master Servicer collected for checks returned for insufficient funds and (vi)
100% of charges for beneficiary statements or demands actually paid by the related borrowers under such Mortgage Loans (and any
related Serviced Pari Passu Companion Loan) that are not Specially Serviced Loans. In addition, the Master Servicer shall be entitled
to retain as additional servicing compensation (other than with respect to a Non Serviced Mortgage Loan) any charges for processing
Mortgagor requests, beneficiary statements or demands, fees in connection with defeasance, if any, and other customary charges,
and amounts collected for checks returned for insufficient funds, in each case only to the extent actually paid by the related
Mortgagor and shall not be required to deposit such amounts in the Collection Account or the Companion Distribution Account pursuant
to Section 3.04(a) or Section 3.04(b), respectively. Subject to Section 3.11(d), the Master Servicer shall
also be entitled to additional servicing compensation in the form of: (i) Penalty Charges to the extent provided in Section
3.11(d), (ii) interest or other income earned on deposits relating to the Trust Fund in the Collection Account or the Companion
Distribution Account in accordance with Section 3.06(b) (but only to the extent of the Net Investment Earnings, if any,
with respect to such account for the period from and including the prior Distribution Date to and including the

 

    -230-

     

    

 

P&I
Advance Date related to the current Distribution Date), (iii) interest or other income earned on deposits in the Servicing Account
which are not required by applicable law or the related Mortgage Loan to be paid to the Mortgagor and (iv) the difference, if
positive, between Prepayment Interest Excess and Prepayment Interest Shortfalls collected on the Mortgage Loans and any Serviced
Pari Passu Companion Loan, during the related Collection Period to the extent not required to be paid as Compensating Interest
Payments. The Master Servicer shall be required to pay out of its own funds all expenses incurred by it in connection with its
servicing activities hereunder (including, without limitation, payment of any amounts due and owing to any of its Sub-Servicers
and the premiums for any blanket Insurance Policy insuring against hazard losses pursuant to Section 3.07), if and to the
extent such expenses are not payable directly out of the Collection Account and the Master Servicer shall not be entitled to reimbursement
therefor except as expressly provided in this Agreement.

 

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

 

Other
than with respect to Penalty Charges, the Master Servicer and the Special Servicer shall each have the right in its sole discretion,
but not any obligation, to reduce or elect not to charge its respective percentage interest in any fee or payment payable to such
party; provided, however without the consent of the affected party, (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 (other
than with respect to Penalty Charges), 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.

 

(b)       As
compensation for its activities hereunder, the Special Servicer shall be entitled to receive the Special Servicing Fee with respect
to each Specially Serviced Loan and

 

    -231-

     

    

 

REO
Loan (other than a Non-Serviced Mortgage Loan and any REO Loan relating to a Non-Serviced Mortgaged Property). As to each Specially
Serviced Loan and REO Loan, the Special Servicing Fee shall accrue from time to time at the Special Servicing Fee Rate and shall
be computed on the basis of the Stated Principal Balance of such Specially Serviced Loan or REO Loan, as the case may be, and
in the same manner as interest is calculated on the Specially Serviced Loans or REO Loans, as the case may be, and, in connection
with any partial month interest payment, for the same period respecting which any related interest payment due on such Specially
Serviced Loan or deemed to be due on such REO Loan is computed. The Special Servicing Fee with respect to any Specially Serviced
Loan or REO Loan shall cease to accrue if a Liquidation Event occurs with respect to the related Mortgage Loan. The Special Servicing
Fee shall be payable monthly, on a loan-by-loan basis, in accordance with the provisions of Section 3.05(a). The right
to receive the Special Servicing Fee may not be transferred in whole or in part except in connection with the transfer of all
of the Special Servicer’s responsibilities and obligations under this Agreement. The Special Servicer shall not be entitled
to any Special Servicing Fees with respect to a Non-Serviced Mortgage Loan.

 

(c)       Additional
servicing compensation in the form of (i) 100% of all Excess Modification Fees related to modifications, waivers, extensions or
amendments of any Specially Serviced Loans, (ii) 100% of all assumption application fees and other similar items received with
respect to Mortgage Loans for which the Special Servicer is processing the underlying assumption related transaction, (iii) 50%
of the portion of any fees payable solely in connection with any modification, waiver, amendment or consent executed in connection
with a defeasance transaction for which the consent, processing or approval of the Special Servicer is required (and specifically
excluding any defeasance fees), (iv) 100% of all assumption, waiver, consent and earnout fees, pursuant to Section 3.08
and Section 3.18 or other actions performed in connection with this Agreement on the Specially Serviced Loans or certain
other similar fees paid by the related Mortgagor and (v) 50% of all Excess Modification Fees and assumption and consent fees pursuant
to Section 3.08 or Section 3.18 and 50% of all earnout fees received with respect to all Non-Specially Serviced
Loans (including any related Serviced Companion Loan, to the extent not prohibited by the related Intercreditor Agreement) and,
in all cases, for which the Special Servicer’s processing, consent or approval is required, shall be promptly paid to the
Special Servicer by the Master Servicer (or directly from the related Mortgagor) to the extent such fees are paid by the Mortgagor
and shall not be required to be deposited in the Collection Account pursuant to Section 3.04(a). Subject to Section
3.11(d), the Special Servicer shall also be entitled to additional servicing compensation in the form of: (i) Penalty Charges
to the extent provided in Section 3.11(d) and (ii) interest or other income earned on deposits relating to the Trust Fund
in the REO Account in accordance with Section 3.06(b) (but only to the extent of the Net Investment Earnings, if any, with
respect to such account for the period from and including the prior Distribution Date to and including the P&I Advance Date
related to such Distribution Date). In addition, the Special Servicer shall also be entitled to retain as additional servicing
compensation (other than with respect to any Non-Serviced Mortgage Loan) reasonable review fees in connection with any Mortgagor
request to the extent such review fees are not prohibited under the related Mortgage Loan documents, and only to the extent actually
paid by the related Mortgagor. The Special Servicer shall also be entitled to additional servicing compensation in the form of
a Workout Fee with respect to each Corrected Loan at the Workout Fee Rate on such Corrected Loan for so long as it remains a Corrected
Loan; provided, however, that after receipt by the Special Servicer of Workout Fees with respect to such Corrected
Loan in an amount equal

 

    -232-

     

    

 

to
$25,000, any Workout Fees in excess of such amount shall be reduced by the Excess Modification Fee Amount; provided, further,
however, that in the event the Workout Fee collected over the course of such workout calculated at the Workout Fee Rate
is less than $25,000, then the Special Servicer shall be entitled to an amount from the final payment on the related Corrected
Loan (including any related Serviced Companion Loan) that would result in the total Workout Fees payable to the Special Servicer
in respect of that Corrected Loan (including any related Serviced Companion Loan) to be $25,000. The Workout Fee shall be reduced
(but not below zero) pursuant to the preceding sentence with respect to each collection on such Corrected Loan from which fee
would otherwise be payable until an amount equal to such Excess Modification Fee Amount has been deducted in full. The Workout
Fee with respect to any Corrected Loan will cease to be payable if such loan again becomes a Specially Serviced Loan; provided
 that a new Workout Fee will become payable if and when such Specially Serviced Loan again becomes a Corrected Loan. The Special
Servicer shall not be entitled to any Workout Fee with respect to a Non-Serviced Mortgage Loan. If the Special Servicer is terminated
(other than for cause) or resigns, it shall retain the right to receive any and all Workout Fees payable in respect of Mortgage
Loans or any related Companion Loan that became Corrected Loans prior to the time of that termination or resignation except the
Workout Fees will no longer be payable if the Corrected Loan subsequently becomes a Specially Serviced Loan. If the Special Servicer
resigns or is terminated (other than for cause), it will receive any Workout Fees payable on Specially Serviced Loans for which
the resigning or terminated Special Servicer had determined to grant a forbearance or cured the event of default through a modification,
restructuring or workout negotiated by the Special Servicer and evidenced by a signed writing, but which had not as of the time
the Special Servicer resigned or was terminated become a Corrected Loan solely because the Mortgagor had not had sufficient time
to make three consecutive timely Periodic Payments and which subsequently becomes a Corrected Loan as a result of the Mortgagor
making such three consecutive timely Periodic Payments except the Workout Fees will no longer be payable if the Corrected Loan
subsequently becomes a Specially Serviced Loan. The successor special servicer shall not be entitled to any portion of such Workout
Fees. The Special Servicer shall not be entitled to receive any Workout Fees after termination for cause. A Liquidation Fee will
be payable with respect to each Specially Serviced Loan (other than a Non-Serviced Mortgage Loan) or REO Property (other than
a Non-Serviced Mortgaged Property) as to which the Special Servicer receives any Liquidation Proceeds or Insurance and Condemnation
Proceeds subject to the exceptions set forth in the definition of Liquidation Fee (such Liquidation Fee to be paid out of such
Liquidation Proceeds, Insurance and Condemnation Proceeds). If, however, Liquidation Proceeds or Insurance and Condemnation Proceeds
are received with respect to any Corrected Loan and the Special Servicer is properly entitled to a Workout Fee, such Workout Fee
will be payable based on and out of the portion of such Liquidation Proceeds and Insurance and Condemnation Proceeds that constitute
principal and/or interest on such Mortgage Loan. Notwithstanding anything herein to the contrary, the Special Servicer shall only
be entitled to receive a Liquidation Fee or a Workout Fee, but not both, with respect to proceeds on any Mortgage Loan. Notwithstanding
the foregoing, with respect to any Companion Loan, the Liquidation Fee, Workout Fee and Special Servicing Fees, if any, will be
computed as provided in the related Intercreditor Agreement or to the extent such Intercreditor Agreement is silent or refers
to this Agreement or indicates such fees are paid in accordance with this Agreement, as provided herein as though such Companion
Loan were a Mortgage Loan. Subject to Section 3.11(d), the Special Servicer will also be

 

    -233-

     

    

 

entitled
to additional fees in the form of Penalty Charges. The Special Servicer shall be required to pay out of its own funds all expenses
incurred by it in connection with its servicing activities hereunder (including, without limitation, payment of any amounts, other
than management fees in respect of REO Properties, due and owing to any of its Sub-Servicers and the premiums for any blanket
Insurance Policy obtained by it insuring against hazard losses pursuant to Section 3.07), if and to the extent such expenses
are not expressly payable directly out of the Collection Account or the REO Account, and the Special Servicer shall not be entitled
to reimbursement therefor except as expressly provided in this Agreement.

 

With
respect to any split fee (other than a fee split with respect to Penalty Charges), the Master Servicer and the Special Servicer
shall each have the right in its sole discretion, but not any obligation, to reduce or elect not to charge its respective percentage
interest in any fee or payment payable to such party; provided, however without the consent of the affected party,
(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 (other than with respect to Penalty Charges), 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.

 

(d)       In
determining the compensation of the Master Servicer or the Special Servicer, as applicable, with respect to Penalty Charges, on
any Distribution Date, the aggregate Penalty Charges collected on any Mortgage Loan (other than a Non-Serviced Mortgage Loan)
and any related Companion Loan since the prior Distribution Date shall be applied (in such order) to reimburse (i) the Master
Servicer, the Special Servicer or the Trustee for interest on Advances on such Mortgage Loan or related Companion Loan, if applicable
(and, in connection with a Non-Serviced Mortgage Loan, the applicable Non-Serviced Master Servicer, the applicable Non-Serviced
Special Servicer or the applicable Non-Serviced Trustee for interest on the servicing advances made by any such party with respect
to a Non-Serviced Whole Loan pursuant to the applicable Non-Serviced PSA, to the extent not prohibited by the applicable Non-Serviced
Intercreditor Agreement) due on such Distribution Date, (ii) the Trust for all interest on Advances previously paid to the Master
Servicer or the Trustee pursuant to Section 3.05(a)(vi) hereof (and, in connection with a Non-Serviced Mortgage Loan, the
related trust for all interest on servicing advances reimbursed by such trust to any party under the applicable Non-Serviced PSA,
which resulted in an additional expense for the Trust, to the extent not prohibited by the applicable Non-Serviced Intercreditor
Agreement) with respect to such Mortgage Loan or related Companion Loan, if applicable and (iii) the Trust for all additional
expenses of the Trust (other than Special Servicing Fees, Workout Fees and Liquidation Fees), including without limitation, inspections
by the Special Servicer and all unpaid Advances incurred since the Closing Date with respect to such Mortgage Loan. Penalty Charges
(other than with respect to a Non-Serviced Mortgage Loan, which shall be payable as additional servicing compensation under the
related Non-Serviced PSA) remaining thereafter shall be distributed to the Master Servicer, if and to the extent accrued while
such Mortgage Loan and any related Companion Loan was a Non-Specially Serviced Loan, and to the Special Servicer, if

 

    -234-

     

    

 

and
to the extent accrued on such Mortgage Loan during the period such Mortgage Loan was a Specially Serviced Loan or REO Loan. Any
Penalty Charges paid or payable as additional servicing compensation to the Master Servicer and the Special Servicer shall be
distributed between the Master Servicer and the Special Servicer, on a pro rata basis, based on the Master Servicer’s and
the Special Servicer’s respective entitlements to such compensation described in the previous sentence. If the Special Servicer
has partially waived any Penalty Charge (part of which accrued prior to the related Servicing Transfer Event), any collections
in respect of such Penalty Charge shall be shared pro rata by the Master Servicer and the Special Servicer based on the respective
portions of such Penalty Charge to which each would otherwise have been entitled. If the Master Servicer has partially waived
any Penalty Charge (part of which accrued subsequent to the occurrence of a Servicing Transfer Event and prior to the date such
Mortgage Loan or Serviced Whole Loan became a Corrected Loan), any collections in respect of such Penalty Charge shall be shared
pro rata by the Master Servicer and the Special Servicer based on the respective portions of such Penalty Charge to which each
would otherwise have been entitled. Notwithstanding the foregoing, Penalty Charges with respect to any Companion Loan will be
allocated pursuant to the applicable Intercreditor Agreement after payment of all related Advances and interest thereon and additional
expenses of the Trust in accordance with this Section 3.11(d).

 

(e)       With
respect to each Distribution Date, the Special Servicer shall deliver or cause to be delivered to the Master Servicer within two
(2) Business Days following the Determination Date, and the Master Servicer shall deliver, to the extent it has received, to the
Certificate Administrator, without charge and on the same day as the Master Servicer is required to deliver the CREFC® Investor
Reporting Package for such Distribution Date, an electronic report (which may include HTML, word or excel compatible format, clean
and searchable PDF format or such other format as mutually agreeable between the Certificate Administrator and the Special Servicer)
that discloses and contains an itemized listing of any Disclosable Special Servicer Fees received by the Special Servicer or any
of its Affiliates, if any, with respect to such Distribution Date; provided that no such report shall be due in any month
during which no Disclosable Special Servicer Fees were received.

 

(f)       The
Special Servicer and its Affiliates shall be prohibited from receiving or retaining any compensation or any other remuneration
(including, without limitation, in the form of commissions, brokerage fees, rebates, or as a result of any other fee-sharing arrangement)
from any Person (including, without limitation, the Trust, any Mortgagor, any property manager, any guarantor or indemnitor in
respect of a Mortgage Loan and any purchaser of any Mortgage Loan or REO Property) in connection with the disposition, workout
or foreclosure of any Mortgage Loan, 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 3.11; provided that such
prohibition shall not apply to Permitted Special Servicer/Affiliate Fees.

 

(g)       Pursuant
to the CREFC® License Agreement, CREFC® shall be paid (according to the payment instructions set
forth on Exhibit JJ hereto or such other payment instructions as CREFC® may provide to the Master Servicer
in writing at least two Business Days prior to the Master Servicer Remittance Date) the CREFC® Intellectual Property
Royalty License Fee on a monthly basis. The Master Servicer shall withdraw from the Collection

 

    -235-

     

    

 

Account
and, to the extent sufficient funds are on deposit therein, pay the CREFC® Intellectual Property Royalty License
Fee to CREFC® in accordance with Section 3.05(a)(xii) on a monthly basis, from funds on deposit in the Collection
Account.

 

Section
3.12 Inspections; Collection of Financial Statements. (a) The Master Servicer (or, with respect to a Specially
Serviced Loan and REO Properties, the Special Servicer) shall perform (at its own expense), or shall cause to be performed
(at its own expense), a physical inspection of each Mortgaged Property relating to a Mortgage Loan (other than a Mortgaged
Property securing a Non-Serviced Mortgage Loan, which is subject to inspection pursuant to the related Non-Serviced PSA) with
a Stated Principal Balance of (i) $2,000,000 or more at least once every twelve (12) months and (ii) less than $2,000,000 at
least once every twenty-four (24) months, in each case, commencing in the calendar year 2018 (and each Mortgaged Property
shall be inspected on or prior to December 31, 2019); provided, however, that if a physical inspection has been
performed by the Special Servicer in the previous twelve (12) months, the Master Servicer shall not be required to perform or
cause to be performed, such physical inspection; provided, further, that if any scheduled payment becomes more
than sixty (60) days delinquent on the related Mortgage Loan, the Special Servicer shall inspect or cause to be inspected the
related Mortgaged Property as soon as practicable after such Mortgage Loan becomes a Specially Serviced Loan and annually
thereafter for so long as such Mortgage Loan remains a Specially Serviced Loan. The cost of such inspection by the Special
Servicer pursuant to the immediately preceding sentence shall be, to the extent not paid by the related Mortgagor, reimbursed
first from Default Interest and late charges constituting additional compensation of the Special Servicer on the related
Mortgage Loan (but with respect to any Serviced Whole Loan, only from amounts available for such purpose under the related
Intercreditor Agreement) and then from the Collection Account, as an expense of the Trust, pursuant to Section
3.05(a)(ii), provided that, with respect to a Serviced Whole Loan, such cost shall be payable, subject to the
terms of the related Intercreditor Agreement (i) with respect to a Serviced Pari Passu Whole Loan, pro
rata and pari
passu, from the related Serviced Pari Passu Mortgage Loan and Serviced Pari Passu
Companion Loan, in accordance with their respective Stated Principal Balances, or (ii) with respect to an AB Whole Loan, first,
from the related AB Subordinate Companion Loan and then,
from any related AB Mortgage Loan (and any Pari Passu Companion Loan(s), on a pro
rata basis) (provided that, with respect to any AB Subordinate Companion Loan,
the foregoing shall not limit or otherwise modify the terms of the related Intercreditor Agreement pursuant to which any
amounts collected with respect to the related Whole Loan are allocated to the related Serviced Mortgage Loan and AB
Subordinate Companion Loan), in each case, prior to being payable out of general collections. The Special Servicer or the
Master Servicer, as applicable, shall prepare or cause to be prepared a written report of each such inspection (A) detailing
the condition of and any damage to the Mortgaged Property to the extent evident from the inspection, (B) specifying the
existence of (i) any vacancy in the Mortgaged Property that the preparer of such report has knowledge of and deems material,
(ii) any sale, transfer or abandonment of the Mortgaged Property of which the preparer of such report has knowledge or that
is evident from the inspection, (iii) any adverse change in the condition of the Mortgaged Property of which the preparer of
such report has knowledge or that is evident from the inspection, and that the preparer of such report deems material and
(iv) any visible material waste committed on the Mortgaged Property of which the preparer of such report has knowledge or
that is evident from the inspection, and (C) including photographs of each inspected Mortgaged Property. The Special Servicer
and the Master Servicer shall each deliver a copy (in

 

    -236-

     

    

 

electronic
format) of each such report prepared by it to the other party, to the Directing Holder ((i) prior to the occurrence and continuance
of a Control Termination Event and (ii) other than with respect to any Excluded Loan), to the Certificate Administrator (for posting
to the Certificate Administrator’s Website for review by Privileged Persons) and to the Trustee within seven (7) Business
Days after the later of (i) the completion of such report or (ii) the Special Servicer’s or the Master Servicer’s,
as applicable, receipt of such report. Within five (5) Business Days after request for copies of such reports by the Rating Agencies,
the Special Servicer or the Master Servicer, as applicable, shall deliver a copy (in electronic format) of each such report prepared
by the Special Servicer and the Master Servicer, as applicable, to the 17g-5 Information Provider for posting to the 17g-5 Information
Provider’s Website. In respect of any Mortgage Loan other than an Excluded Loan as to such party and prior to the occurrence
of a Consultation Termination Event, the Master Servicer shall deliver or make available a copy of each such report to the Directing
Holder and upon request to each Controlling Class Certificateholder (which request may state that such items may be delivered
until further notice) (except, after the occurrence and continuance of a Consultation Termination Event or with respect to any
Specially Serviced Loan that is an Excluded Loan as to such party).

 

(b)       The
Special Servicer, in the case of any Specially Serviced Loan, and the Master Servicer, in the case of any Non-Specially Serviced
Loan shall make efforts consistent with the Servicing Standard to collect promptly and review from each related Mortgagor quarterly
and annual operating statements, financial statements, budgets and rent rolls of the related Mortgaged Property, and the quarterly
and annual financial statements of such Mortgagor, whether or not delivery of such items is required pursuant to the terms of
the related Mortgage Loan documents and any other reports or documents required to be delivered under the terms of the Mortgage
Loans (and each Serviced Companion Loan), if delivery of such items is required pursuant to the terms of the related Mortgage
Loan (and each Serviced Companion Loan) documents. The Master Servicer and the Special Servicer shall not be required to request
such operating statements or rent rolls more than once if the related Mortgagor is not required to deliver such statements pursuant
to the terms of the Mortgage Loan documents. In addition, the Special Servicer shall cause quarterly and annual operating statements,
budgets and rent rolls to be regularly prepared in respect of each REO Property and shall collect all such items promptly following
their preparation. The Special Servicer shall deliver all such items to the Master Servicer within five (5) Business Days of receipt,
and the Master Servicer and the Special Servicer, as applicable, shall deliver copies of all the foregoing items so collected
to the Certificate Administrator, in electronic format, in each case within sixty (60) days of its receipt thereof, but in no
event, in the case of annual statements, later than June 30 of each year commencing June 30, 2018. Upon the request of any Privileged
Person (other than the NRSROs) to receive copies of such items, the Master Servicer or the Special Servicer, as applicable, shall
deliver electronic copies of such items to the Certificate Administrator to be posted on the Certificate Administrator’s
Website. The Master Servicer or the Special Servicer, as applicable, shall deliver, upon request of any NRSRO, copies of any or
all of the foregoing items so collected thereby to the 17g-5 Information Provider pursuant to Section 3.13(c) who shall
post such items to the 17g-5 Information Provider’s Website.

 

In
addition, the Master Servicer (with respect to Non-Specially Serviced Loans and Non-Serviced Mortgage Loan) or the Special Servicer
(with respect to Specially Serviced

 

    -237-

     

    

 

Loans
that are not, and REO Properties that do not relate to, Non-Serviced Mortgage Loans), as applicable, shall prepare with respect
to each Mortgaged Property and REO Property:

 

(i)       Within
forty-five (45) days after receipt of a quarterly operating statement, if any, commencing following the receipt of such quarterly
operating statement for the quarter ending December 31, 2017, a CREFC® Operating Statement Analysis Report (but
only to the extent the related Mortgagor is required by the related Mortgage documents to deliver and does deliver, or otherwise
agrees to provide and does provide, such information) for such Mortgaged Property or REO Property as of the end of that calendar
quarter, provided, however, that any analysis or report with respect to the first calendar quarter of each year
shall not be required to the extent provided in the then-current applicable CREFC® guidelines (it being understood
that as of the Closing Date, the applicable CREFC® guidelines provide that such analysis or report with respect
to the first calendar quarter (in each year) is not required for a Mortgaged Property unless such Mortgaged Property is analyzed
on a trailing 12 month basis, or if the related Serviced Mortgage Loan is on the CREFC® Servicer Watch List). The
Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced Loans
and REO Properties), as applicable, shall deliver or make available copies (in electronic format) each CREFC® Operating
Statement Analysis Report and, upon request, the related operating statements (in each case, promptly following the initial preparation
and each material revision thereof) to the Certificate Administrator, the Operating Advisor and, upon request, each related Companion
Holder (with respect to any Serviced Companion Loan) by electronic means.

 

(ii)       Within
forty-five (45) days after receipt of any an annual operating statement or rent rolls for each calendar year commencing following
the receipt of such annual operating statement for the calendar year ending December 31, 2017, a CREFC® NOI Adjustment
Worksheet (but only to the extent the related Mortgagor is required by the related Mortgage Loan documents to deliver and does
deliver, or otherwise agrees to provide and does provide, such information), presenting the computation to “normalize”
the full year net operating income and debt service coverage numbers used by the Master Servicer in preparing the CREFC®
Comparative Financial Status Report. The Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer
(with respect to Specially Serviced Loans and REO Properties), as applicable, shall deliver or make available copies (in electronic
format) each CREFC® NOI Adjustment Worksheet and, upon request, the related operating statements or rent rolls
(in each case, promptly following the initial preparation and each material revision thereof) to the Certificate Administrator
each related Companion Holder (with respect to any Serviced Companion Loan) and, upon request, the Operating Advisor, by electronic
means.

 

(c)       At
or before 12:00 p.m. (New York City time) on each Determination Date, the Special Servicer shall prepare and deliver or cause
to be delivered to the Master Servicer and, prior to the occurrence and continuance of a Consultation Termination Event, the Directing
Certificateholder, the CREFC® Special Servicer Loan File and any applicable CREFC® Loan Liquidation
Reports, CREFC® Loan Modification Reports and CREFC® REO Liquidation Reports with respect to the
Specially Serviced Loans (excluding, for the Directing Holder, any Excluded Loans as to such party) and any REO Properties (other
than a

 

    -238-

     

    

 

Non-Serviced
Mortgaged Property), providing the information required of the Special Servicer in an electronic format, reasonably acceptable
to the Master Servicer as of the Business Day preceding such Determination Date, which CREFC® Special Servicer

NOI Adjustment Worksheet and a CREFC® Operating Statement Analysis Report, in each case with the supporting
financial statements, budgets, operating statements and rent rolls submitted by the Mortgagor.

 

(d)       Not
later than 5:00 p.m. (New York City time) on the Master Servicer Remittance Date beginning November 2017, the Master Servicer
shall prepare (if and to the extent necessary) and deliver or cause to be delivered in electronic format to the Certificate Administrator
the following reports and data files: (A) to the extent the Master Servicer has received the CREFC® Special Servicer
Loan File at the time required, the most recent CREFC® Delinquent Loan Status Report, CREFC® Historical

delivered in electronic format to the Certificate Administrator any applicable CREFC® Loan Liquidation Reports,
CREFC® Loan Modification Reports and CREFC® REO Liquidation Reports received from the Special Servicer.
Not later than 2:00 p.m. (New York City time) two (2) Business Days prior to the Distribution Date beginning in October 2017,
the Master Servicer shall deliver or cause to be delivered to the Certificate Administrator via electronic format the CREFC®

subsection be required to reflect information that has not been collected by or delivered to the Master Servicer, or any payments
or collections not received by the Master Servicer, as of the close of business on the Business Day prior to the Business Day
on which the report is due.

 

Not
later than 5:00 p.m. (New York City time) on the Master Servicer Remittance Date beginning October 2017, the Master Servicer shall
deliver to the Certificate Administrator the CREFC® Schedule AL File in EDGAR-Compatible Format; provided
that the Master Servicer shall have no obligation to prepare or deliver any such CREFC® Schedule AL File unless
the Depositor has delivered the items required by Section 2.01(i). If the CREFC® Schedule AL File is not
provided by 5:00 p.m. (New York City time) on the Master Servicer Remittance Date, the Certificate Administrator shall request
such CREFC® Schedule AL File

 

    -239-

     

    

 

from
the Master Servicer via email at KC_Investor_Reporting@KeyBank.com, with a copy to the Depositor at chuck.lee@credit-suisse.com.
In preparing the CREFC® Schedule AL File and any Schedule AL Additional File for any given Distribution Date, and
without any due diligence, investigation or verification, the Master Servicer shall be entitled to conclusively rely, absent manifest
error, on the content, completeness, accuracy and compliance with any applicable requirements of Items 1111(h) and 1125 of Regulation
AB and Item 601(b) of Regulation S-K under the Securities Act as in effect on the Closing Date of the Initial Schedule AL File,
any Initial Schedule AL Additional File and Annex A-1 to the Prospectus. The Master Servicer may concurrently with the delivery
of the related CREFC® Schedule AL File, deliver any related Schedule AL Additional File in EDGAR-Compatible Format
to the Certificate Administrator. The CREFC® Schedule AL File and the Schedule AL Additional File shall each be
a single file. Neither the Certificate Administrator nor the Master Servicer shall be required to combine multiple CREFC®
Schedule AL Files or Schedule AL Additional Files, unless, solely with respect to the Master Servicer, multiple Sub-Servicers
prepare and submit such CREFC® Schedule AL Files or Schedule AL Additional Files to the Master Servicer. The Certificate
Administrator shall not be required to review, redact, reconcile, edit or verify the content, completeness or accuracy of the
information contained in any CREFC® Schedule AL File or any Schedule AL Additional File. The Certificate Administrator
shall not be deemed to have actual knowledge of the contents of any CREFC® Schedule AL File or Schedule AL Additional
File solely by its receipt thereof.

 

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

 

(e)       The
Special Servicer shall deliver to the Master Servicer the reports and information required of the Special Servicer pursuant to
Section 3.12(b) and Section 3.12(c), and the Master Servicer shall deliver or make available to the Certificate
Administrator the reports and data files set forth in Section 3.12(b). The Master Servicer may, absent manifest error,
conclusively rely on the reports and/or data to be provided by the Special Servicer pursuant to Section 3.12(b) and Section
3.12(c). The Certificate Administrator may, absent manifest error, conclusively rely on the reports and/or data to be provided
by the Master Servicer pursuant to Section 3.12(b). In the case of information or reports to be furnished by the Master
Servicer to the Certificate Administrator pursuant to Section 3.12(b), to the extent that such information or reports are,
in turn, based on information or reports to be provided by the Special Servicer pursuant to Section 3.12(b) or Section
3.12(c) and to the extent that such reports are to be prepared and delivered by the Special Servicer pursuant to Section
3.12(b) or Section 3.12(c), the Master Servicer shall have no obligation to provide such information or reports to
the Certificate Administrator until it has received the requisite information or reports from the Special Servicer, and the Master
Servicer shall not be in default hereunder due to a delay in providing the reports required by Section 3.12(b) caused by
the Special Servicer’s failure to timely provide any information or report required under Section 3.12(b) or Section
3.12(c) of this Agreement.

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

 

(g)       Unless
otherwise specifically stated herein, if the Master Servicer or the Special Servicer is required to deliver any statement, report
or information under any provisions of this Agreement, the Master Servicer or the Special Servicer, as the case may be, may satisfy
such obligation by (x) physically delivering a paper copy of such statement, report or information, (y) delivering such statement,
report or information in a commonly used electronic format or (z) except with respect to information to be provided to the Certificate
Administrator or any Companion Holder and, prior to the occurrence of a Consultation Termination Event, the Directing Holder,
making such statement, report or information available on the Master Servicer’s or the Special Servicer’s Internet
website, unless this Agreement expressly specifies a particular method of delivery.

 

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

3.13 Access to Certain Information. (a) Each of the Master
Servicer and the Special Servicer shall provide or cause to be provided to the Certificate Administrator, and the Certificate
Administrator shall afford access to any Mortgage Loan Seller and to any Certificateholder that is a federally insured financial
institution, the OCC, the FDIC, the Board of Governors of the Federal Reserve System of the United States of America and the supervisory
agents and examiners of such boards and such corporations, and any other federal or state banking or insurance regulatory authority
that may exercise authority over any such Certificateholder, and to each Holder of a Non-Registered Certificate, access to any
documentation or information regarding the Mortgage Loans (other than any Non-Serviced Mortgage Loan) and, in the case of a Mortgage
Loan that is a portion of a Serviced Whole Loan, the related Companion Loan, and the Trust within its control which may be required
by applicable law. At the election of the Master Servicer, the Special Servicer or the Certificate Administrator, such access
may be afforded to such Person identified above by the delivery of copies of information as requested by such Person and the Master
Servicer, the Special Servicer or the Certificate Administrator shall be permitted to require payment (other than from the

 

    -241-

     

    

 

Directing
Holder (prior to the occurrence of a Consultation Termination Event) and the Trustee and the Certificate Administrator on its
own behalf or on behalf of the Certificateholders, as applicable) of a sum sufficient to cover the reasonable out-of-pocket costs
incurred by it in making such copies. Such access shall (except as described in the preceding sentence) be afforded without charge
but only upon reasonable prior written request and during normal business hours at the offices of the Certificate Administrator
or the Custodian.

 

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

 

Upon
the reasonable request of any Certificateholder or Certificate Owner (or with respect to any AB Subordinate Companion Loan, the
holder of such AB Subordinate Companion Loan) that has delivered an Investor Certification to the Master Servicer or the Special
Servicer, as applicable, the Master Servicer (with respect to Non-Specially Serviced Loans) or the Special Servicer (with respect
to Specially Serviced Loans), as applicable, may provide (or forward electronically) at the expense of such Certificateholder
or holder of such AB Subordinate Companion Loan, as applicable, copies of any appraisals, operating statements, rent rolls and
financial statements (in each case, solely relating to the related Serviced Whole Loan, if requested by the holder of an AB Subordinate
Companion Loan) obtained by the Master Servicer or the Special Servicer, as the case may be; provided that, in connection
with such request, the Master Servicer or the Special Servicer, as applicable, may require a written confirmation executed by
the requesting Person substantially in such form as may be reasonably acceptable to

 

    -242-

     

    

 

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

 

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

    -246-

The

Notwithstanding
the foregoing, all Excluded Information shall be made available under a separate tab or heading designated “Excluded Information”
on the Certificate Administrator’s Website (and not under any of the tabs or headings described in items (i)  through
(vii) above) and made available to Privileged Persons other than any Excluded Controlling Class Holder that is a Borrower
Party (unless a loan-by-loan segregation is later performed by the Certificate Administrator in which case such access shall only
be prohibited with respect to the related Excluded Controlling Class Loan(s)).

 

Any
Person that is a Borrower Party shall only be entitled to access (a) the Distribution Date Statements, and the following items
made available to the general public: the Prospectus, this Agreement, the Mortgage Loan Purchase Agreements and the SEC filings
on the Certificate Administrator’s Website, and (b) in the case of the Directing Holder or a Controlling Class Certificateholder,
if any such Person becomes an Excluded Controlling Class Holder, upon delivery to the Master Servicer, the Special Servicer, the
Operating Advisor, the Certificate Administrator and the Trustee in physical form of an investor certification substantially in
the forms of Exhibit P-1D and Exhibit P-1B and upon delivery to the Certificate Administrator in physical form of
an investor certification substantially in the form of Exhibit P-1F, which shall include each of the CTSLink User ID associated

Website.

 

In
the case of the Directing Holder or a Controlling Class Certificateholder that is not an Excluded Controlling Class Holder, upon
delivery of an investor certification substantially in the form of Exhibit P-1B hereto, such Directing Holder or Controlling
Class Certificateholder shall be entitled to access all information on the Certificate Administrator’s Website. The Master
Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee may each rely on (i) an investor
certification in the form of Exhibit P-1B hereto from the Directing Holder or a Controlling Class Certificateholder to
the effect that

 

    -247-

     

    

 

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

 

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

 

Each
of the Master Servicer, the Special Servicer, the Operating Advisor and the Certificate Administrator shall be entitled to conclusively
rely on delivery from the Directing Holder or a Controlling Class Certificateholder of an investor certification substantially
in the

 

    -248-

     

    

 

form
of Exhibit P-1B that it is not or is no longer an Excluded Controlling Class Holder. To the extent the Directing Holder
or a Controlling Class Certificateholder receives access pursuant to this Agreement to any Excluded Information on the Certificate
Administrator’s Website or otherwise receives access to such Excluded Information, such Directing Holder or Controlling
Class Certificateholder shall be deemed to have agreed that it (i) will not directly or indirectly provide any such Excluded Information
to (A) the related Borrower Party, (B) any related Excluded Controlling Class Holder, (C) any employees or personnel of such Directing
Holder or Controlling Class Certificateholder or any of its Affiliate involved in the management of any investment in the related
Borrower Party or the related Mortgaged Property or (D) to its actual knowledge, any non-Affiliate that holds a direct or indirect
ownership interest in the related Borrower Party, and (ii) will maintain sufficient internal controls and appropriate policies
and procedures in place in order to comply with the obligations described in clause (i) above.

 

To
the extent the Risk Retention Consultation Party or a Holder of a VRR Interest receives access pursuant to this Agreement to any
information solely related to a Mortgage Loan with respect to which such party is a Borrower Party (which shall include any Asset
Status Reports, Final Asset Status Reports (or summaries thereof)), inspection reports related to Specially Serviced Loans conducted
by the Special Servicer or any Excluded Special Servicer and which may include any Operating Advisor reports delivered to the
Certificate Administrator regarding the Special Servicer’s net present value determination or any Appraisal Reduction Amount
calculations delivered pursuant to Section 3.26(d), and any Officer’s Certificates delivered by the Trustee, the
Master Servicer or the Special Servicer, supporting any determination that any Advance was (or, if made, would be) a Nonrecoverable
Advance, but in each case other than information with respect to such Mortgage Loan that is aggregated with information of other
Mortgage Loans at a pool level), on the Certificate Administrator’s Website or otherwise receives access to such information,
such Risk Retention Consultation Party or Holder of a VRR Interest shall be deemed to have agreed that it (i) will not directly
or indirectly provide any such information to (A) the related Borrower Party, (B) any employees or personnel of such Risk Retention
Consultation Party or Holder of a VRR Interest or any of its Affiliates involved in the management of any investment in the related
Borrower Party or the related Mortgaged Property or (C) to its actual knowledge, any non-Affiliate that holds a direct or indirect
ownership interest in the related Borrower Party, and (ii) will maintain sufficient internal controls and appropriate policies
and procedures in place in order to comply with the obligations described in clause (i) above. For the avoidance of doubt,
any file or report contained in the CREFC® Investor Reporting Package (CREFC® IRP) (other than the
CREFC® Special Servicer Loan File relating to any such Excluded Loan) shall be considered information that is aggregated
with information of other Mortgage Loans at a pool level.

 respect to such Distribution Date Statements and CREFC® reports) shall
be provided by the Certificate Administrator to third parties (including Bloomberg, L.P., Thomson Reuters Corporation, Trepp,

also deliver, produce or otherwise make available through its website or otherwise, any additional information relating to the

Persons who deliver an Investor Certification in accordance with this Section 3.13 and the Rating Agencies (collectively,
the “Disclosure Parties”) (only to the extent such additional information is simultaneously delivered to the
17g-5 Information Provider for posting on the 17g-5 Information Provider’s Website in accordance with the provisions of
Section 3.13(c)), in each case, except to the extent doing so is prohibited by this Agreement (including without limitation,
any prohibitions on dissemination of any confidential information, including, without limitation, any Privileged Information),
applicable law or by the related Mortgage Loan documents. Each of the Master Servicer and the Special Servicer shall be entitled
to (i) indicate the source of such information and affix thereto any disclaimer it deems appropriate in its discretion and/or
(ii) require that the recipient of such information (A) except for the Depositor and the Rating Agencies, enter into
(x) an Investor Certification, (y) a confidentiality agreement substantially in the form of Exhibit X or
(z) a “click-through” confidentiality agreement if such information is being provided through the Master Servicer’s

confidential nature of such information. In connection with providing access to or copies of the information described in this
Section 3.13(e) to current or prospective Certificateholders the form of confidentiality agreement used by the Master
Servicer or the Special Servicer, as applicable, shall be: (i) in the case of a Certificateholder, an Investor Certification

(except that such Certificateholder may provide such information (x) to its auditors, legal counsel and regulators and (y) to
any other Person that holds or is contemplating the purchase of any Certificate or interest therein (provided that such
other Person confirms in writing such ownership interest or prospective ownership interest and agrees to keep such information
confidential)); and (ii) in the case of a prospective purchaser of Certificates or interests therein or an investment advisor
related thereto, an Investor Certification indicating that such Person is a prospective purchaser of a Certificate or an interest
therein or an investment advisor related thereto and is requesting the information for use in evaluating a possible investment
in Certificates and will otherwise keep such information confidential with no further

 

    -253-

     

    

 

 dissemination (except that such Certificateholder
may provide such information to its auditors, legal counsel and regulators). In the case of a licensed or registered investment
advisor acting on behalf of a current or prospective Certificateholder, the Investor Certification shall be executed and delivered
by both the investment advisor and such current or prospective Certificateholder.

 

Neither
the Master Servicer nor the Special Servicer shall be liable for its dissemination of information in accordance with this Agreement
or by others in violation of the terms of this Agreement. Neither the Master Servicer nor the Special Servicer shall be responsible
or have any liability for the completeness or accuracy of the information delivered, produced or otherwise made available pursuant
to this Section 3.13 unless such information was produced by the Master Servicer or the Special Servicer, as applicable.

 

(f)            The Master Servicer, the Special Servicer, the Certificate Administrator and the Trustee shall be permitted (but not obligated)
to orally communicate with the Rating Agencies regarding any of the Mortgage Loan documents and any other matter related to the
Mortgage Loans, the related Mortgaged Properties, the related Mortgagors or any other matters relating to this Agreement or related
Intercreditor Agreement; provided that such party summarizes the information provided to the Rating Agencies in such communication
in writing and provides the 17g-5 Information Provider with such written summary in accordance with the procedures set forth in
Section 3.13(c) the same day such communication takes place; provided, further, that the summary of
such oral communications shall not identify which Rating Agency the communication was with. The 17g-5 Information Provider shall
post such written summary on the 17g-5 Information Provider’s Website in accordance with the procedures set forth in Section 3.13(c).

 

In
connection with the delivery by the Master Servicer or the Special Servicer, as applicable, to the 17g-5 Information Provider
of any information, report, notice or document for posting to the 17g-5 Information Provider’s Website, the 17g-5 Information
Provider shall notify the Master Servicer or the Special Servicer, as applicable, of when such information, report, notice or
document has been posted to the 17g-5 Information Provider’s Website. 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 or Rating
Agencies so long as such information, report, notice or document (i) was previously provided to the 17g-5 Information Provider
or (ii) is simultaneously provided to the 17g-5 Information Provider.

 

(g)           The Special Servicer, subject to the limitations on delivery of Privileged Communications, shall deliver to the Operating Advisor
such reports and other information produced or otherwise available to the Directing Holder or the Risk Retention Consultation
Party (in each case, other than, prior to the occurrence and continuance of a Control Termination Event, any Asset Status Reports
that are not Final Asset Status Reports), or Certificateholders generally, requested by the Operating Advisor in support of the
performance of its obligations under this Agreement in electronic format.

 

(h)           None of the foregoing restrictions in this Section 3.13 or otherwise in this Agreement shall prohibit or restrict
oral or written communications, or providing information, between the Master Servicer, the Operating Advisor, the Asset Representations
Reviewer or the

 

    -254-

     

    

 

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

 

(i)          
The costs and expenses of compliance with this Section 3.13 by the Depositor, the Master Servicer, the Special Servicer,
the Certificate Administrator, the Trustee, the Operating Advisor, the Asset Representations Reviewer and any other party hereto
shall not be additional expenses of the Trust, but shall be borne by the applicable party hereto.

 

Section 3.14     Title to REO Property; REO Account. (a)  If title to any Mortgaged Property is acquired (and thus becomes REO
Property), the deed or certificate of sale shall be issued in the name of the Trust where permitted by applicable law or regulation
and consistent with customary servicing procedures, and otherwise, in the name of the Trustee or its nominee on behalf of the
Certificateholders and, if applicable, on behalf of the related Companion Holders, in the case of a Serviced Companion Loan. REO
Property with respect to a Non-Serviced Mortgage Loan is excluded for all purposes of this Section 3.14. The Special
Servicer, on behalf of the Trust and, if applicable, the related Serviced Companion Noteholder, shall sell any REO Property prior
to the close of the third calendar year following the year in which the Trust acquires ownership of such REO Property, within
the meaning of Treasury Regulations Section 1.856-6(b)(1), for purposes of Section 860G(a)(8) of the Code, unless the
Special Servicer either (i) applies for an extension of time no later than sixty (60) days prior to the close of the third
calendar year in which it acquired ownership (or the period provided in the then applicable REMIC Provisions) and such qualifying
extension is granted or is not denied (an “REO Extension”) by the Internal Revenue Service to sell such REO
Property or (ii) obtains for the Trustee and the Certificate Administrator an Opinion of Counsel, addressed to the Trustee
and the Certificate Administrator, to the effect that the holding by the Trust of such REO Property subsequent to the close of
the third calendar year following the year in which

 

    -255-

     

    

 

 acquisition occurred will not cause an Adverse REMIC Event to occur. If the
Special Servicer is granted or not denied the REO Extension contemplated by clause (i) of the immediately preceding
sentence or obtains the Opinion of Counsel contemplated by clause (ii) of the immediately preceding sentence, the
Special Servicer shall sell such REO Property within such longer period as is permitted by such REO Extension or such Opinion
of Counsel, as the case may be. Any expense incurred by the Special Servicer in connection with its being granted the REO Extension
contemplated by clause (i) of the second preceding sentence or its obtaining the Opinion of Counsel contemplated by
clause (ii) of the second preceding sentence, shall be an expense of the Trust payable out of the Collection Account
pursuant to Section 3.05(a).

 

(b)           The Special Servicer shall segregate and hold all funds collected and received in connection with any REO Property separate and
apart from its own funds and general assets. If an REO Acquisition shall occur, the Special Servicer shall establish and maintain
one or more REO Accounts, held on behalf of the Trustee for the benefit of the Certificateholders and, if applicable, on behalf
of any related Companion Holder(s), as applicable, as their interest shall appear, and the Trustee (as holder of the Lower-Tier
Regular Interests), for the retention of revenues and other proceeds derived from each REO Property. The REO Account shall be
an Eligible Account. The Special Servicer shall deposit, or cause to be deposited, in the REO Account, within one (1) Business
Day after receipt of properly identified funds, all REO Revenues, Insurance and Condemnation Proceeds and Liquidation Proceeds
received in respect of an REO Property. Funds in the REO Account may be invested in Permitted Investments in accordance with Section 3.06.
The Special Servicer shall give notice to the Trustee, the Certificate Administrator, and the Master Servicer of the location
of the REO Account when first established and of the new location of the REO Account prior to any change thereof.

 

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

 

    -256-

     

    

 

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

 

Section 3.15     Management of REO Property. (a)  If title to any REO Property is acquired, the Special Servicer shall manage,
conserve, protect, operate and lease such REO Property (other than any Non-Serviced Mortgaged Property) for the benefit of the
Certificateholders and the related Companion Holders, as applicable, and the Trustee (as holder of the Lower-Tier Regular Interests)
solely for the purpose of its timely disposition and sale in a manner that does not cause such REO Property to fail to qualify
as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or result in the receipt by the
Trust or any Serviced Companion Noteholder of any “income from non-permitted assets” within the meaning of Section 860F(a)(2)(B)
of the Code or result in an Adverse REMIC Event. Subject to the foregoing, however, the Special Servicer shall have full power
and authority to do any and all things in connection therewith as are in the best interests of and for the benefit of the Certificateholders
(and, in the case of each Serviced Whole Loan, the related Companion Holder(s)) and the Trustee (as holder of the Lower-Tier Regular
Interests) all as a collective whole (taking into account the subordinate or pari passu nature of any Companion Loan, as
the case may be) (as determined by the Special Servicer in its reasonable judgment in accordance with the Servicing Standard).
Notwithstanding anything to the contrary herein, REO Property with respect to a Non-Serviced Mortgage Loan is excluded for all
purposes of this Section 3.15. Subject to this Section 3.15, the Special Servicer may allow the Trust
or any commercial mortgage securitization that holds any Serviced Companion Loan to earn “net income from foreclosure property”
within the meaning of Section 860G(d) of the Code if it determines that earning such income is in the best interests of Certificateholders
and, if applicable, any related Companion Holder(s) on a net after-tax basis as compared with net leasing such REO Property or
operating such REO Property on a different basis. In connection therewith, the Special Servicer shall deposit or cause to be deposited
on a daily basis (and in no event later than one (1) Business Day following receipt of such properly identified funds) in the
applicable REO Account all revenues received by it with respect to each REO Property and the related REO Loan, and shall withdraw
from the REO Account, to the extent of amounts on deposit therein with respect to such REO Property, funds necessary for the proper
operation, management, leasing and maintenance of such REO Property, including, without limitation:

 

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

 

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

 

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

 

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

 

To
the extent that amounts on deposit in the REO Account in respect of any REO Property are insufficient for the purposes set forth
in clauses (i) through (iv) above with respect to such REO Property, the Master Servicer (subject to receiving
notice from the Special Servicer in accordance with the procedures set forth elsewhere in this Agreement) shall advance from its

 

    -257-

     

    

 

own funds such amount as is necessary for such purposes unless (as evidenced by an Officer’s Certificate delivered to the
Trustee, the Special Servicer, the Depositor, the Certificate Administrator and the Directing Holder (with respect to the Directing
Holder, in respect of any Mortgage Loan other than an Excluded Loan as to such party, and prior to the occurrence and continuance
of a Consultation Termination Event)) such advances would, if made, constitute Nonrecoverable Servicing Advances.

 

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

 

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

 

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

 

(iii)          authorize or permit any construction on any REO Property, other than the completion of a building or other improvement thereon,
and then only if more than 10% of the construction of such building or other improvement was completed before default on the related
Mortgage Loan, if applicable, became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or

 

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

 

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

 

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

 

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

 

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

 

    -258-

     

    

 

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

 

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

 

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

 

The
Special Servicer shall be entitled to enter into any agreement with any Independent Contractor performing services for it related
to its duties and obligations hereunder for indemnification of the Special Servicer by such Independent Contractor, and nothing
in this Agreement shall be deemed to limit or modify such indemnification.

 

(d)          
When and as necessary, the Special Servicer shall send to the Trustee, the Certificate Administrator and the Master Servicer a
statement prepared by the Special Servicer setting forth the amount of net income or net loss, as determined for federal income
tax purposes, resulting from the operation and management of a trade or business on, the furnishing or rendering of a non-customary
service to the tenants of, or the receipt of any other amount not constituting Rents from Real Property in respect of, any REO
Property in accordance with Sections 3.15(a) and 3.15(b).

 

Section 3.16     Sale of Defaulted Loans and REO Properties. (a) (i) Within thirty (30) days after a Defaulted Loan has become a Specially
Serviced Loan, the Special Servicer shall order (but shall not be required to have received) an Appraisal and within thirty (30)
days of receipt of the Appraisal shall determine the fair value of such Defaulted Loan in accordance with the Servicing Standard;
provided, however, that if the Special Servicer is then in the process of obtaining an Appraisal with respect to
the related Mortgaged Property, the Special Servicer shall make its fair value determination as soon as reasonably practicable
(but in any event within thirty (30) days) after its receipt of such an Appraisal. The Special Servicer may, from time to time,
adjust its fair value determination based upon changed circumstances, new information and other relevant factors, in each instance
in accordance with a review of such circumstances and new information in accordance with the Servicing Standard; provided
that the Special Servicer shall promptly notify the Master Servicer in writing of the initial fair value determination and any
adjustment to its fair value determination.

 

(ii)         If any Mortgage Loan or Serviced Companion Loan subject to an Intercreditor Agreement is a Specially Serviced Loan or to the extent
otherwise required pursuant to the terms of the related Intercreditor Agreement, then the Special Servicer shall promptly notify
in writing the Master Servicer, any related Companion Holder and any related mezzanine lender, as applicable, of any events requiring
notice under the Intercreditor Agreement in accordance with the terms thereof. Thereafter, any related

 

    -259-

     

    

 

 Companion Holder and related
mezzanine lender, as applicable, will, notwithstanding anything in this Section 3.16 to the contrary, have the option
to purchase the related Mortgage Loan and cure defaults relating thereto as and to the extent set forth in the related Intercreditor
Agreement.

 

(iii)        If any Mortgage Loan not subject to an Intercreditor Agreement becomes a Specially Serviced Loan, or if the related Companion
Holder or related mezzanine lender, as applicable, for any such Mortgage Loan subject to an Intercreditor Agreement has not previously
exercised the option to purchase the Mortgage Loan pursuant to the previous paragraph, the Special Servicer may offer to sell
to any Person any Specially Serviced Loan (to the extent consistent with any related Intercreditor Agreement and Section 3.16(d))
or may offer to purchase any Specially Serviced Loan, if and when the Special Servicer determines, consistent with the Servicing
Standard, that such a sale would be in the best economic interests of the Certificateholders or, if applicable, the Certificateholders
and the Serviced Companion Noteholder(s) (as a collective whole as if the Trust and the Serviced Companion Loan Noteholder(s)
constituted a single lender), on a net present value basis. In the case of any Non-Serviced Mortgage Loan, under certain limited
circumstances permitted under the related Intercreditor Agreement, to the extent that such Non-Serviced Mortgage Loan is not sold
together with the related Non-Serviced Companion Loan by the applicable Non-Serviced Special Servicer for the related Non-Serviced
Whole Loan, the Special Servicer will be entitled to sell (with the consent of the Directing Certificateholder and after consulting
with the Risk Retention Consultation Party pursuant to Section 6.08(a), in each case, if no Control Termination Event
has occurred and is continuing and such Non-Serviced Mortgage Loan is not an Excluded Loan as to such party) such Non-Serviced
Mortgage Loan if it determines in accordance with the Servicing Standard that such action would be in the best interests of the
Certificateholders. The Special Servicer is required to give the Trustee, the Certificate Administrator, the Master Servicer,
the Operating Advisor (other than in respect of any applicable Excluded Loan) and the Directing Holder and the Risk Retention
Consultation Party (in the case of the Directing Holder and the Risk Retention Consultation Party, other than in respect of any
Excluded Loan as to such party) not less than ten (10) days’ prior written notice of its intention to sell any Defaulted
Loan, in which case, subject to Section 3.16(a)(iv), the Special Servicer is required to accept the highest offer received
from any person for such Specially Serviced Loan in an amount at least equal to the outstanding principal balance plus all accrued
and unpaid interest and outstanding costs and expenses and certain other amounts pursuant to this Agreement (the “Par
Purchase Price”) or, at its option, if it has received no offer at least equal to the Par Purchase Price therefor, purchase
such Specially Serviced Loan at such Par Purchase Price.

 

(iv)       (A)  In the case of a Specially Serviced Loan as to which a default has occurred and is continuing, in the absence of
any offer at least equal to the Par Purchase Price pursuant to clause (iii) above (or purchase by the Special Servicer
for such price), the Special Servicer shall, subject to subclause (B) below, accept the highest offer received from
any Person that is determined by the Special Servicer to be a fair price for such Specially Serviced Loan, if the highest offeror
is a Person other than an Interested Person. In determining whether any offer from a Person other than an Interested Person constitutes
a fair price for any Defaulted Loan or REO Property, the Special Servicer shall

 

    -260-

     

    

 

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

 

Notwithstanding
anything contained in the preceding paragraph to the contrary, if the Trustee is required to determine whether a cash offer by
an Interested Person constitutes a fair price and the offer is less than the Par Purchase Price, the Trustee may, at its option,
(at the expense of the Interested Person) designate an independent third party expert in real estate or commercial mortgage loan
matters with at least 5 years’ experience in valuing loans similar to the subject Mortgage Loan or Serviced Whole Loan,
as the case may be, that has been selected with reasonable care by the Trustee to determine if such cash offer constitutes a fair
price for such Mortgage Loan or Serviced Whole Loan. If the Trustee designates such a third party to make such determination,
the Trustee shall be entitled to rely conclusively upon such third party’s determination. The reasonable fees of, and the
costs of all appraisals, inspection reports and broker opinions of value incurred by any such third party shall be covered by,
and shall be reimbursable, from the offering Interested Person and the Special Servicer shall use efforts consistent with the
Servicing Standard to collect payment from such Interested Person. If such expense is not paid by the applicable Interested Person
within thirty (30) days of demand for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing
Advance (provided that the Trustee shall not engage a third party expert whose fees exceed a commercially reasonable amount
as determined by the Trustee) but the Special Servicer shall continue to use efforts consistent with the Servicing Standard to
collect such amounts from the applicable Interested Person. Neither the Trustee, in its individual capacity, nor any of its Affiliates
may make an offer for or purchase any Specially Serviced Loan.

 

(B)       
  The Special Servicer shall not be obligated to accept the highest offer if the Special Servicer determines (in consultation with
the Directing Holder and the Risk Retention Consultation Party, subject to the

 

    -261-

     

    

 

limitations on consultation set forth in Section 6.08(a) (in each case, unless a Consultation Termination Event
shall have occurred and be continuing and other than with respect to any Mortgage Loan that is an Excluded Loan as to such
party) and, in the case of a Serviced Whole Loan or an REO Property related to a Serviced Whole Loan, the related Companion
Holder), in accordance with the Servicing Standard (and subject to the requirements of any related Intercreditor Agreement),
that the rejection of such offer would be in the best interests of the Holders of Certificates and, in the case of a sale of
a Serviced Whole Loan, the related Companion Holder(s) (as a collective whole, as if such Certificateholders and, if
applicable, the related Companion Holder(s) constituted a single lender). In addition, the Special Servicer may accept a
lower offer if it determines, in accordance with the Servicing Standard (and subject to the requirements of any related
Intercreditor Agreement), that the acceptance of such offer would be in the best interests of the Holders of Certificates
and, in the case of a sale of a Serviced Whole Loan, the related Companion Holder(s) (as a collective whole, as if such
Certificateholders and, if applicable, the related Companion Holder constituted a single lender (and with respect to any AB
Whole Loan, taking into account the subordinate nature of the related Subordinate Companion Loan)) (for example, if the
prospective buyer making the lower offer is more likely to perform its obligations, or the terms offered by the prospective
buyer making the lower offer are more favorable); provided that the offeror is not the Special Servicer or a Person
that is an Affiliate of the Special Servicer. The Special Servicer shall use reasonable efforts to sell all Defaulted Loans
prior to the Rated Final Distribution Date. For the avoidance of doubt, the Trustee shall have no obligation to make any fair
value determination, to the extent required to do so pursuant to this Section 3.16, on the basis of anything
other than the related Appraisal.

 

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

 

(b)          
(i)  (A)  The Special Servicer may purchase any REO Property at the Par Purchase Price therefor (in the case
of a Serviced Whole Loan, such purchase shall be a purchase of the entire REO Property, including the portion relating to the
related Companion Loan). The Special Servicer may also offer to sell to any Person any REO Property (in the case of a Serviced
Whole Loan, such sale shall be a sale of the entire REO Property, including the portion relating to the related Companion Loan),
if and when the Special Servicer determines, consistent with the Servicing Standard, that such a sale would be in the best economic
interest of the Trust and the related Companion Holders. The Special Servicer shall give the Trustee, the Master Servicer, each
Companion Holder, the Certificate Administrator and the Directing Holder and the Risk Retention Consultation Party (in the case
of the Directing Holder and the Risk Retention Consultation Party, in respect of any Mortgage Loan other than an Excluded Loan
as to such party and prior to the occurrence and continuance of a Consultation Termination Event) not less than ten (10) days’
prior written notice of the Purchase Price and its intention to (i) purchase any

 

    -262-

     

    

 

 REO Property at the Par Purchase Price therefor
or (ii) sell any REO Property, in which case the Special Servicer shall accept the highest offer received from any Person
for any REO Property in an amount at least equal to the Par Purchase Price therefor. To the extent permitted by applicable law,
and subject to the Servicing Standard, the Master Servicer, an Affiliate of the Master Servicer, the Special Servicer or an Affiliate
of the Special Servicer, or an employee of either of them may act as broker in connection with the sale of any REO Property and
may retain from the proceeds of such sale a brokerage commission that does not exceed the commission that would have been earned
by an independent broker pursuant to a brokerage agreement entered into at arm’s length.

 

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

 

(C)       
 The Special Servicer shall not be obligated by either of the foregoing paragraphs or otherwise to accept the highest offer if
the Special Servicer determines, in accordance with the Servicing Standard, that rejection of such offer would be in the best
interests of the Certificateholders and, with respect to any Serviced Whole Loan or the related Companion Holder, and in either
case, as a collective whole (taking into account the subordinate or pari passu nature of any Serviced Companion Loans).
In addition, the Special Servicer may accept a lower offer if it determines, in accordance with the Servicing Standard, that acceptance
of such offer would be in the best interests of the Certificateholders and, with respect to any Serviced Whole Loan or the related
Companion Holder, and in either case, as a collective whole (taking into account the subordinate or pari passu nature of
any Serviced Companion Loans) (for example, if the prospective buyer making the lower offer is more likely to perform its obligations,
or the terms offered by the prospective buyer making the lower offer are more favorable); provided that the offeror is
not the Special Servicer or a Person that is an Affiliate of the Special Servicer.

 

(D)        
In determining whether any offer received from an Interested Person represents a fair price for any REO Property, the Trustee
shall obtain and may conclusively rely on the opinion of an Independent appraiser or other Independent expert in real estate matters
retained by the Trustee in connection with making such determination. The reasonable cost of such Independent appraiser or other
Independent expert shall be an expense of the

 

    -263-

     

    

 

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

 

(ii)         Subject to the Servicing Standard, the Special Servicer shall act on behalf of the Trust and the related Companion Holders in
negotiating and taking any other action necessary or appropriate in connection with the sale of any REO Property, including the
collection of all amounts payable in connection therewith. A sale of any REO Property shall be without recourse to, or representation
or warranty by, the Trustee, the Depositor, the Master Servicer, the Special Servicer, the Certificate Administrator, the Operating
Advisor or the Trust (except that any contract of sale and assignment and conveyance documents may contain customary warranties
of title, so long as the only recourse for breach thereof is to the Trust) and, if consummated in accordance with the terms of
this Agreement, none of the Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator, the Operating
Advisor nor the Trustee shall have any liability to the Trust or any Certificateholder or related Companion Holder (if applicable)
with respect to the purchase price therefor accepted by the Special Servicer or the Trustee.

 

(c)           Any sale of a Defaulted Loan or any REO Property shall be for cash only (unless changes in the REMIC Provisions or authoritative
interpretations thereof made or issued subsequent to the Startup Day allow a sale for other consideration).

 

(d)          
With respect to each Serviced Pari Passu Whole Loan, pursuant to the terms of the related Intercreditor Agreement and this Agreement,
if the related Serviced Pari Passu Whole Loan becomes a Defaulted Loan, and if the Special Servicer determines to sell the related
Mortgage Loan that has become a Defaulted Loan in accordance with this Section 3.16, then the Special Servicer shall
sell the related Serviced Pari Passu Companion Loan together with such Mortgage Loan as one whole loan and shall require that
all offers be submitted to the Special Servicer in writing. To the extent a determination is required to be made hereunder as
to whether any cash offer constitutes a fair price for any Serviced Whole Loan, such determination shall be made by the Trustee
if the offeror is an Interested Person. Notwithstanding the foregoing, the Special Servicer shall not be permitted to sell the
related Mortgage Loan together with the related Serviced Pari Passu Companion Loan(s) if it becomes a defaulted Whole Loan without
the written consent of the holder of the related Serviced Pari Passu Companion Loan

 

    -264-

     

    

 

(provided that such consent is not
required if the holder of the Serviced Pari Passu Companion Loan is the Mortgagor or an affiliate of the Mortgagor) unless the
Special Servicer has delivered to the holder of the related Serviced Pari Passu Companion Loan: (a) at least fifteen (15) Business
Days prior written notice of any decision to attempt to sell such Serviced Whole Loan; (b) at least ten (10) days prior to the
permitted sale date, a copy of each bid package (together with any material amendments to such bid packages) received by the Special
Servicer in connection with any such proposed sale; (c) at least ten (10) days prior to the proposed sale date, a copy of the
most recent appraisal for such Serviced Pari Passu Whole Loan, and any documents in the servicing file reasonably requested by
the holder of the related Serviced Pari Passu Companion Loan that are material to the sale price of the Serviced Pari Passu Whole
Loan; and (d) until the sale is completed, and a reasonable period of time (but no less time than is afforded to other offerors
and the Directing Certificateholder and the Risk Retention Consultation Party) prior to the proposed sale date, all information
and other documents being provided to other offerors and all leases or other documents that are approved by the Master Servicer
or the Special Servicer in connection with the proposed sale. The holder of the related Serviced Pari Passu Companion Loan (or
its representative) will be permitted to submit an offer at any sale of such Whole Loan; however, the related Mortgagor
and its agents and Affiliates shall not be permitted to submit an offer at such sale. Notwithstanding the foregoing, with respect
to each Serviced Whole Loan, the holder of the related Companion Loan may waive any of the delivery or timing requirements set
forth in this paragraph with respect to the related Whole Loan. If the Trustee is required to determine whether a cash offer by
an Interested Person constitutes a fair price, the Trustee may (at its option and at the expense of the offering Interested Person
purchaser) designate an independent third party expert in real estate or commercial mortgage loan matters with at least 5 years’
experience in valuing or investing in loans similar to the subject Mortgage Loan, that has been selected with reasonable care
by the Trustee to determine if such cash offer constitutes a fair price for such Mortgage Loan. The Trustee shall act in a commercially
reasonable manner in making such determination. If the Trustee designates such a third party to make such determination, the Trustee
shall be entitled to rely conclusively upon such third party’s determination. The reasonable fees of, and the costs of all
appraisals, inspection reports and broker opinions of value incurred by any such third party shall be covered by, and shall be
reimbursable, from the offering Interested Person and the Special Servicer shall use efforts consistent with the Servicing Standard
to collect payment from such Interested Person. If such expense is not paid by the applicable Interested Person within thirty
(30) days of demand for payment, such expense shall be reimbursable to the Trustee by the Master Servicer as a Servicing Advance
but the Special Servicer shall continue to use efforts consistent with the Servicing Standard to collect such amounts from the
applicable Interested Person.

 

(e)           (i)  Notwithstanding anything in this Section 3.16 to the contrary, pursuant to the terms of the related
Intercreditor Agreement, the holder of the related AB Subordinate Companion Loan for each applicable Serviced Whole Loan will
have the right to purchase the related Mortgage Loan or related REO Property, as applicable. Such right of the holder of the AB
Subordinate Companion Loan shall be given priority over any provision described in this Section 3.16 as and to the
extent set forth in the related Intercreditor Agreement. If the related Mortgage Loan or related REO Property is purchased by
the holder of such AB Subordinate Companion Loan, repurchased by the applicable Mortgage Loan Seller or otherwise ceases to be
subject to this Agreement, the related AB Subordinate Companion Loan will no longer be

 

    -265-

     

    

 

 subject to this Agreement. In addition,
with respect to the Serviced AB Whole Loan, pursuant to the terms of the related Intercreditor Agreement and this Agreement, if
the related Serviced AB Whole Loan becomes a Defaulted Loan, and if the Special Servicer determines to sell the related Mortgage
Loan that has become a Defaulted Loan in accordance with this Section 3.16, then the Special Servicer will not be required to
sell the related AB Subordinate Companion Loan together with such Mortgage Loan as one whole loan. If no AB Control Appraisal
Period exists, the Special Servicer may not sell the AB Subordinate Companion Loan without the prior consent of the holder of
the AB Subordinate Companion Loan.  If an AB Control Appraisal Period has occurred and is continuing, the Special Servicer
has the right (but not the obligation) to sell the AB Subordinate Companion Loan without the consent of the holder of the AB Subordinate
Companion Loan.

 

(ii)           Notwithstanding anything in this Section 3.16 to the contrary, any mezzanine lender will have the right to purchase
the related Mortgage Loan or REO Property, as applicable, and cure defaults relating thereto, as and to the extent set forth in
the related Intercreditor Agreement.

 

(f)           
Unless otherwise provided in an Intercreditor Agreement the sale of any Mortgage Loan pursuant to this Section 3.16 will
be on a servicing released basis.

 

(g)          
In the event the Master Servicer or the Special Servicer has the right to purchase any Companion Loan on behalf of the Trust pursuant
to the related Intercreditor Agreement, neither the Master Servicer nor the Special Servicer shall exercise such right.

 

Section 3.17     Additional Obligations of Master Servicer and Special Servicer. (a)  The Master Servicer shall deliver all Compensating
Interest Payments (other than the portion of any Compensating Interest Payment allocated to a Serviced Pari Passu Companion Loan)
to the Certificate Administrator for deposit in the Lower-Tier REMIC Distribution Account on each P&I Advance Date, without
any right of reimbursement therefor. The Master Servicer shall deliver the portion of any Compensating Interest Payment allocated
to a Serviced Pari Passu Companion Loan to the Companion Paying Agent for deposit in the Companion Distribution Account on each
P&I Advance Date, without any right of reimbursement therefor.

 

(b)          
The Master Servicer or the Special Servicer, as applicable, shall provide to each Companion Holder any reports or notices required
to be delivered to such Companion Holder pursuant to the related Intercreditor Agreement.

 

(c)          Upon the determination that a previously made Advance is a Nonrecoverable Advance, to the extent that the reimbursement thereof
would exceed the full amount of the principal portion of general collections on the Mortgage Loans, deposited in the Collection
Account and available for distribution on the next Distribution Date, the Master Servicer or the Trustee, each at its own option
and in its sole discretion, as applicable, instead of obtaining reimbursement for the remaining amount of such Nonrecoverable
Advance pursuant to Section 3.05(a)(v) immediately, as an accommodation may elect to refrain from obtaining such reimbursement
for such portion of the Nonrecoverable Advance during the one month collection period ending on the then-current Determination
Date, for successive one-month periods for a total period not to exceed twelve (12) months (provided that, other than in
the case of an 

 

    -266-

     

    

 

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

 

The
foregoing shall not, however, be construed to limit any liability that may otherwise be imposed on such Person for any failure
by such Person to comply with the conditions to making such an election under Section 3.17 or to comply with the terms
of Section 3.17 and the other provisions of this Agreement that apply once such an election, if any, has been made;
provided, however, that the fact that a decision to recover such Nonrecoverable Advances over time, or not to do
so, benefits some classes of Certificateholders to the detriment of other classes shall not, with respect to the Master Servicer
or the Special Servicer, as applicable, constitute a violation of the Servicing Standard and/or with respect to the Trustee (solely
in its capacity as Trustee), constitute a violation of any fiduciary duty to Certificateholders or any contractual obligation
hereunder. If the Master Servicer or the Trustee, as applicable, determines, in its sole discretion, that its ability to fully
recover the Nonrecoverable Advances has been compromised, then the Master Servicer or the Trustee, as applicable, shall be entitled
to immediate reimbursement of Nonrecoverable Advances with interest thereon at the Reimbursement Rate from all amounts in the
Collection Account for such

 

    -267-

     

    

 

Distribution Date (deemed first from principal and then interest). Any such election
by any such party to refrain from reimbursing itself or obtaining reimbursement for any Nonrecoverable Advance or portion thereof
with respect to any one or more collection periods shall not limit the accrual of interest at the Reimbursement Rate on such Nonrecoverable
Advance for the period prior to the actual reimbursement of such Nonrecoverable Advance. The Master Servicer’s or the Trustee’s,
as applicable, agreement to defer reimbursement of such Nonrecoverable Advances as set forth above is an accommodation to the
Certificateholders and shall not be construed as an obligation on the part of the Master Servicer or the Trustee, as applicable,
or a right of the Certificateholders. Nothing herein shall be deemed to create in the Certificateholders a right to prior payment
of distributions over the Master Servicer’s or the Trustee’s, as applicable, right to reimbursement for Advances (deferred
or otherwise) and accrued interest thereon. In all events, the decision to defer reimbursement or to seek immediate reimbursement
of Nonrecoverable Advances shall be deemed to be in accordance with the Servicing Standard and none of the Master Servicer, the
Trustee or the other parties to this Agreement shall have any liability to one another or to any of the Certificateholders or
any of the Companion Holders for any such election that such party makes as contemplated by Section 3.17 or for any
losses, damages or other adverse economic or other effects that may arise from such an election.

 

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

 

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

 

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

 

Section 3.18     Modifications, Waivers, Amendments and Consents. (a)  Except as set forth in Section 3.08(a), Section 3.08(b),
this Section 3.18(a), Section 3.18(d), Section 3.18(h), Section 3.18(i) and Section 6.08,
but subject to any other conditions set forth thereunder (including, without limitation, the Special Servicer’s processing
and/or consent rights pursuant to this subsection (a) with respect to any modification, waiver or amendment that constitutes a
Special Servicer Decision or Major Decision) and, with respect to any Mortgage Loan (other than any Non-Serviced Mortgage Loan)
or any Serviced Whole Loan, (and with

 

    -268-

     

    

 

respect to any Serviced Whole Loan, subject to the rights of the related Companion Holder to advise or consult with
the Master Servicer or the Special Servicer, as applicable, with respect to, or to consent to, a modification, waiver
or amendment, in each case, pursuant to the terms of the related Intercreditor Agreement), the Master Servicer shall not
agree to any modification, waiver or amendment to the terms of a Mortgage Loan and/or Companion Loan that constitutes a Major
Decision or a Special Servicer Decision (unless, with respect to a Non-Specially Serviced Loan, the Master Servicer and the
Special Servicer mutually agree that the Master Servicer shall process such request); provided that no
extension entered into pursuant to this Section 3.18(a) shall extend the Maturity Date beyond the earlier of
(i) five (5) years prior to the Rated Final Distribution Date and (ii) in the case of a Mortgage Loan secured
solely or primarily by a leasehold estate and not also the related fee interest, the date twenty (20) years or, to the extent
consistent with the Servicing Standard giving due consideration to the remaining term of the Ground Lease, ten (10) years,
prior to the expiration of such leasehold estate. If such extension would extend the Maturity Date of such Mortgage Loan
and/or related Companion Loan for more than twelve (12) months from and after the original Maturity Date of such Mortgage
Loan and/or related Companion Loan and such Mortgage Loan and/or related Companion Loan is not in default or default with
respect thereto is not reasonably foreseeable, prior to any such extension, (1) the Master Servicer shall provide the
Trustee, the Certificate Administrator, the Special Servicer, the Operating Advisor, the Directing Holder and the Risk
Retention Consultation Party (in the case of the Directing Holder and the Risk Retention Consultation Party, (i) prior
to the occurrence and continuance of a Consultation Termination Event and (ii) other than with respect to any Mortgage
Loan that is an Excluded Loan as to such party), with an Opinion of Counsel (at the expense of the related Mortgagor to the
extent permitted under the Mortgage Loan documents and, if not required or permitted to be paid by the Mortgagor, to be paid
as an expense of the Trust in accordance with Section 3.11(d)) that such extension would not constitute
a “significant modification” of the Mortgage Loan and/or Serviced Companion Loan within the meaning of
Treasury Regulations Section 1.860G-2(b) and (2) subject to the Servicing Standard, the Special Servicer shall (A)
obtain the consent of the Directing Holder and, with respect to Specially Serviced Loans, consult with the Risk
Retention Consultation Party pursuant to Section 6.08(a) (in each case, (i) prior to the occurrence and
continuance of a Control Termination Event and (ii) other than with respect to a Mortgage Loan that is an Excluded Loan
as to such party) or (B) consult with the Directing Holder and the Risk Retention Consultation Party pursuant to Section 6.08(a)
(in each case, (i) after the occurrence and during the continuance of a Control Termination Event, but (solely in the
case of the Directing Holder) prior to a Consultation Termination Event and (ii) other than with respect to any Excluded
Loan as to such party) (which consent or consultation shall be coordinated through the Special Servicer). Notwithstanding
the foregoing, subject to the rights of the related Companion Holder to advise the Master Servicer with respect to, or
consent to, such modification, waiver or amendment pursuant to the terms of the related Intercreditor Agreement, and subject
to the Special Servicer’s processing and/or consent rights pursuant to this subsection (a), the Master Servicer,
with respect to Non-Specially Serviced Loans, without the consent of or consultation with the Special Servicer, the
Operating Advisor or the Directing Holder, may modify or amend the terms of any Mortgage Loan and/or related Serviced
Companion Loan in order to (i) cure any ambiguity or mistake therein or (ii) correct or supplement any provisions
therein which may be inconsistent with any other provisions therein or correct any error; provided that, if the
Mortgage Loan (other than any Non-Serviced Mortgage Loan) and/or related

 

    -269-

     

    

 

Serviced Companion Loan is not in default or default with respect thereto
is not reasonably foreseeable, such modification or amendment would not be a “significant modification” of the Mortgage
Loan and/or related Serviced Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b).

 

Subject
to Section 6.08, applicable law and the Mortgage Loan and/or related Serviced Companion Loan documents, neither the
Master Servicer nor the Special Servicer shall permit the substitution of any Mortgaged Property (or any portion thereof) for
one or more other parcels of real property at any time the Mortgage Loan and/or related Serviced Companion Loan is not in default
pursuant to the terms of the related Mortgage Loan and/or related Serviced Companion Loan documents or default with respect thereto
is not reasonably foreseeable unless (i) the Master Servicer or the Special Servicer, as applicable, obtains Rating Agency
Confirmation from each Rating Agency (and delivers such Rating Agency Confirmation to the Directing Holder and the Risk Retention
Consultation Party, if permitted by the applicable Rating Agency) and a confirmation of any applicable rating agencies that such
action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion
Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner
as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25))
and (ii) such substitution would not be a “significant modification” of the Mortgage Loan and/or related Serviced
Companion Loan within the meaning of Treasury Regulations Section 1.860G-2(b) or otherwise cause an Adverse REMIC Event (and
the Master Servicer or the Special Servicer, as applicable, may obtain and rely upon an Opinion of Counsel (at the expense of
the related Mortgagor if not prohibited by the terms of the related Mortgage Loan documents, and if so prohibited, at the expense
of the Trust) with respect thereto).

 

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

 

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

 

(b)          
If the Special Servicer determines that a modification, waiver or amendment (including, without limitation, the forgiveness or
deferral of interest or principal or

 

    -270-

     

    

 

the substitution of collateral pursuant to the terms of the Mortgage Loan (other than any
Non-Serviced Mortgage Loan) and/or related Serviced Companion Loan or otherwise, the release of collateral or the pledge of additional
collateral) of the terms of a Specially Serviced Loan with respect to which a payment default or other material default has occurred
or a payment default or other material default is, in the Special Servicer’s judgment, reasonably foreseeable (as evidenced
by an Officer’s Certificate of the Special Servicer), is reasonably likely to produce a greater recovery on a net present
value basis (the relevant discounting to be performed at the related Mortgage Rate) to the Trust and, if applicable, the related
Companion Holders, as the holders of the related Serviced Companion Loan, than liquidation of such Specially Serviced Loan, then
the Special Servicer may agree to a modification, waiver or amendment of such Specially Serviced Loan, subject to (x) the
provisions of this Section 3.18(b) and Section 3.18(c), (y) with respect to any Major Decision, (a) with
respect to any Mortgage Loan (other than any Excluded Loan as to such party), the approval of the Directing Holder (prior to the
occurrence and continuance of a Control Termination Event or after the occurrence and continuance of Consultation Termination
Event, upon consultation with the Directing Certificateholder) and (b) with respect to any Specially Serviced Loan (other than
any Excluded Loan as to such party), consultation with the Risk Retention Consultation Party as provided in Section 6.08;
provided that with respect to any Serviced AB Whole Loan, prior to the occurrence and continuance of a related AB Control
Appraisal Period, the approval of the holder of the related AB Subordinate Companion Loan will be required to the extent set forth
in the related Intercreditor Agreement and the Directing Holder shall have no consent or consultation rights and the Risk Retention
Consultation Party shall have no consultation rights regarding the matter; and (z) additionally, with respect to a Serviced
Whole Loan, the rights of the related Serviced Companion Noteholder, to advise or consult with the Special Servicer with respect
to, or consent to, such modification, waiver or amendment, in each case, pursuant to the terms of the related Intercreditor Agreement;
provided that in the case of any release or substitution of collateral (other than a defeasance), the Special Servicer
shall have obtained an Opinion of Counsel that such release or substitution would not be a “significant modification”
of the Mortgage Loan within the meaning of Treasury Regulations Section 1.860G-2(b) or otherwise cause an Adverse REMIC Event.
Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Holder or, if
the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class (regardless of whether
an Operating Advisor Consultation Event has occurred and is continuing), the Special Servicer shall consult with the Operating
Advisor (telephonically or electronically), on a non-binding basis, in connection with the related transactions involving proposed
Major Decisions that it is processing or for which its consent is required and consider alternative actions recommended by the
Operating Advisor, in respect thereof, in accordance with the procedures set forth in Section 6.08 for consulting
with the Operating Advisor.

 

With
respect to non-Specially Serviced Loans, the Master Servicer, prior to taking any action with respect to any Major Decision or
any Special Servicer Decision shall be required to refer the request to the Special Servicer. The Special Servicer shall process
the request directly. However, if the Master Servicer and Special Servicer mutually agree that the Master Servicer shall process
such request, the Master Servicer shall prepare and submit its written analysis and recommendation to the Special Servicer with
all information reasonably available to the Master Servicer that the Special Servicer may reasonably request in order to withhold
or grant its consent, and in all cases the Special Servicer shall be entitled to approve or disapprove

 

    -271-

     

    

 

any modification, waiver
or amendment that constitutes such a Major Decision or a Special Servicer Decision. In any case with respect to any Major Decision
or Special Servicer Decision in connection with a non-Specially Serviced Loan, each of the Master Servicer and the Special Servicer
shall be entitled to 50% of any related fee whether or not the Master Servicer processes such request.

 

The
Special Servicer shall use its reasonable efforts to the extent reasonably possible to cause each Specially Serviced Loan to fully
amortize prior to the Rated Final Distribution Date and shall not agree to a modification, waiver or amendment of any term of
any Specially Serviced Loan if such modification, waiver or amendment would (1) extend the maturity date of any such Specially
Serviced Loan to a date occurring later than the earlier of (a) five years prior to the Rated Final Distribution Date and (b)
if such Specially Serviced Loan is secured solely or primarily by a leasehold estate and not also the related fee interest, the
date occurring twenty (20) years or, to the extent consistent with the Servicing Standard giving due consideration to the remaining
term of the ground lease and, ((i) prior to the occurrence and continuance of a Control Termination Event and (ii) other than
with respect to any Excluded Loan) with the consent of the Directing Certificateholder, ten (10) years prior to the expiration
of such leasehold estate (including any options to extend such leasehold estate exercisable unilaterally by the related Mortgagor),
or (2) provide for the deferral of interest unless interest accrues on the related Mortgage Loan, or Serviced Whole Loans
generally at the related Mortgage Rate.

 

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

 

(d)          
To the extent consistent with this Agreement, the Master Servicer (subject to the Special Servicer’s consent rights pursuant
to Section 3.18(a) if any such waiver, modification or amendment constitutes a Major Decision or Special Servicer
Decision) or the Special Servicer may, consistent with the Servicing Standard, agree to any waiver, modification or amendment
of a Mortgage Loan and/or Serviced Companion Loan that is not in default or as to which default is not reasonably foreseeable
only if the contemplated waiver, modification or amendment (i) will not be a “significant modification” of the
Mortgage Loan within the meaning of Treasury Regulations Section 1.860G-2(b) and (ii) will not cause an Adverse REMIC Event
to occur. In making this determination, the Master Servicer or Special Servicer may obtain and rely upon (and shall provide to
the Trustee and the Certificate Administrator if obtained) an Opinion of Counsel (at the expense of the related Mortgagor or such
other Person requesting such modification or, if such expense cannot be collected from the related Mortgagor or such other Person,
to be paid out of the Collection Account pursuant to Section 3.05(a); provided that the Master Servicer or
the Special Servicer, as the case may be, shall use its reasonable efforts to collect such fee from the Mortgagor or such other
Person to the extent permitted under the

 

    -272-

     

    

 

 related Mortgage Loan documents). Notwithstanding the foregoing, neither the Master Servicer
nor the Special Servicer may waive the payment of any Yield Maintenance Charge or the requirement that any prepayment of a Mortgage
Loan be made on a Due Date, or if not made on a Due Date, be accompanied by all interest that would be due on the next Due Date
with respect to any Mortgage Loan or Serviced Companion Loan that is not a Specially Serviced Loan.

 

(e)           Subject to Section 3.18(c), the Master Servicer and the Special Servicer each may, as a condition to its granting
any request by a Mortgagor for consent, modification (including extensions), waiver or indulgence or any other matter or thing,
the granting of which is within the Master Servicer’s or the Special Servicer’s, as the case may be, discretion pursuant
to the terms of the instruments evidencing or securing the related Mortgage Loan or Companion Loan and is permitted by the terms
of this Agreement, require that such Mortgagor pay to the Master Servicer or the Special Servicer, as the case may be, as additional
servicing compensation, a reasonable or customary fee, for the additional services performed in connection with such request;
provided that the charging of such fee is not a “significant modification” of the Mortgage Loan within the
meaning of Treasury Regulations Section 1.860G-2(b).

 

(f)           All modifications (including extensions), waivers and amendments of the Mortgage Loans and/or Companion Loans entered into pursuant
to this Section 3.18 shall be in writing, signed by the Master Servicer or the Special Servicer, as the case may be,
and the related Mortgagor (and by any guarantor of the related Mortgage Loan, if such guarantor’s signature is required
by the Special Servicer in accordance with the Servicing Standard).

 

(g)          With respect to any modification, waiver or amendment for which it is responsible for processing pursuant to Section 3.18
hereof, the Special Servicer shall notify the Master Servicer, the Trustee, the Certificate Administrator, the Operating Advisor
(after the occurrence and during the continuance of an Operating Advisor Consultation Event), the Directing Holder and the Risk
Retention Consultation Party (in the case of the Directing Holder, other than following the occurrence and continuance of a Consultation
Termination Event, and in the case of the Directing Holder or the Risk Retention Consultation Party, other than with respect
to any Excluded Loan as to such party), the applicable Companion Holder, the related Mortgage Loan Seller (if such Mortgage Loan
Seller is not a Master Servicer or Sub-Servicer of such Mortgage Loan, the Directing Holder or the Risk Retention Consultation
Party) and the 17g-5 Information Provider (which shall promptly post such notice on the 17g-5 Information Provider’s Website
in accordance with Section 3.13(c)) in writing of any modification, waiver or amendment (in each case, after it is
finalized and executed) of any term of any Mortgage Loan or Companion Loan that is modified, waived or amended and the date thereof.
With respect to any modification, waiver or amendment (in each case, after it is finalized and executed) for which it is responsible
for processing pursuant to Section 3.18 hereof, the Master Servicer shall provide written notice of any such modification,
waiver or amendment to the Trustee, the Certificate Administrator, the Special Servicer (and the Special Servicer shall forward
such notice to the Directing Holder and the Risk Retention Consultation Party (in the case of the Directing Holder, only prior
to the occurrence and continuance of a Consultation Termination Event and in the case of the Directing Holder or the Risk Retention
Consultation Party, other than with respect to an Excluded Loan as to such party), the applicable Companion Holder, the related
Mortgage Loan Seller (so long as such Mortgage Loan Seller is not a Master Servicer or Sub-Servicer of such Mortgage Loan or the
Directing Holder or Risk Retention Consultation Party) and the 17g-5

 

    -273-

     

    

 

Information Provider (which shall promptly post such notice
on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)). The party responsible for delivering
notice shall deliver to the Custodian with a copy to the Master Servicer (if such notice is being delivered by the Special Servicer)
for deposit in the related Mortgage File, an original counterpart of the agreement relating to such modification, waiver or amendment,
promptly (and in any event within ten (10) Business Days) following the execution thereof, with a copy to the applicable Companion
Holder, if any. Following receipt of the Master Servicer’s or the Special Servicer’s, as applicable, delivery of the
aforesaid modification, waiver or amendment to the Certificate Administrator, the Certificate Administrator shall forward a copy
thereof to each Holder of a Certificate (other than the Class Z or Class R Certificates) upon request. With respect to the processing
of any modification, waiver or consent related to any Mortgagor incurring additional debt or mezzanine debt, the Special Servicer
(if the Special Servicer processes such modification, waiver or consent pursuant to Section 3.18(a)) or the Master
Servicer (if the Master Servicer processes such modification, waiver or consent pursuant to Section 3.18(a)) shall,
on or before the later of (i) 3:00 p.m. on the related P&I Advance Date and (ii) five (5) Business Days immediately
following the Master Servicer or the Special Servicer, as applicable, obtaining actual knowledge of the incurrence of such additional
debt or mezzanine debt, deliver notice of the Mortgagor’s incurrence of such debt, substantially in the form of Exhibit KK,
to cts.sec.notifications@wellsfargo.com and an Additional Disclosure Notification in the form attached hereto as Exhibit EE.
The notice contemplated in the preceding sentence shall set forth, to the extent the Special Servicer or Master Servicer, as applicable,
has the requisite information or can reasonably obtain such information, (1) the amount of additional debt that was incurred in
the related Collection Period, (2) the total debt service coverage ratio calculated on the basis of such Mortgage Loan and additional
debt, and (3) the aggregate LTV Ratio calculated on the basis of such Mortgage Loan and additional debt. In the event that either
(i) the CREFC® Investor Reporting Package is amended to include such information set forth above, in a manner
reasonably acceptable to the Master Servicer, the Special Servicer and Certificate Administrator, as applicable, and the Master
Servicer confirms with the Certificate Administrator that such amended CREFC® Investor Reporting Package enables
the Certificate Administrator to include such information on Form 10-D in a manner reasonably acceptable to the Certificate Administrator,
or (ii) the Trust is no longer subject to the Exchange Act, the additional report in the form of Exhibit KK shall
no longer be required hereunder. From time to time, the Master Servicer, the Special Servicer and Certificate Administrator may
agree on a different delivery time and format for the information set forth in this paragraph.

 

(h)          The Master Servicer shall process all defeasance transactions, subject to the Special Servicer’s consent with respect to
any Special Servicer Decision relating to a defeasance. Notwithstanding the foregoing, the Master Servicer shall not permit (or,
with regard to any Non-Serviced Mortgage Loan, take any act in furtherance of) the substitution of any Mortgaged Property pursuant
to the defeasance provisions of any Mortgage Loan or a Serviced Whole Loan unless such defeasance complies with Treasury Regulations
Section 1.860G-2(a)(8)(ii) and the Master Servicer has received (i) replacement collateral consisting of government
securities within the meaning of Treasury Regulations Section 1.860G-2(a)(8)(ii), which satisfies the requirements of the
applicable Mortgage Loan documents, in an amount sufficient to make all scheduled payments under the related Mortgage Loan (or
defeased portion thereof) when due, (ii) a certificate of an Independent certified public accountant to the effect that such
substituted property will provide cash flows sufficient to meet

 

    -274-

     

    

 

all payments of interest and principal (including payments at
maturity) on such Mortgage Loan or Serviced Whole Loan in compliance with the requirements of the terms of the related Mortgage
Loan documents and, if applicable, Companion Loan documents, (iii) one or more Opinions of Counsel (at the expense of the
related Mortgagor) to the effect that the Trustee, on behalf of the Trust, will have a first priority perfected security interest
in such substituted Mortgaged Property; provided, however, that, to the extent consistent with the related Mortgage
Loan documents and, if applicable, Companion Loan documents, the related Mortgagor shall pay the cost of any such opinion as a
condition to granting such defeasance, (iv) to the extent consistent with the related Mortgage Loan documents and, if applicable,
Companion Loan documents, the Mortgagor shall establish a single purpose entity to act as a successor mortgagor, if so required
by the Rating Agencies, (v) to the extent permissible under the related Mortgage Loan documents and, if applicable, Companion
Loan documents, the Master Servicer shall use its reasonable efforts to require the related Mortgagor to pay all costs of such
defeasance, including but not limited to the cost of maintaining any successor mortgagor, and (vi) to the extent permissible
under the Mortgage Loan documents and, if applicable, Companion Loan documents, the Master Servicer shall obtain, at the expense
of the related Mortgagor, Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced
Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same
manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25);
provided, further, however, that no such confirmation from any Rating Agency shall be required to the extent
that the Master Servicer has delivered a defeasance certificate substantially in the form of Exhibit U hereto for
any Mortgage Loan that (together with any Mortgage Loans cross-collateralized with such Mortgage Loans) is: (i) a Mortgage
Loan with a Cut-off Date Balance less than $20,000,000, (ii) a Mortgage Loan that represents less than 5% of the aggregate
Cut-off Date Balance of all Mortgage Loans and (iii) a Mortgage Loan that is not one of the ten largest Mortgage Loans by
Stated Principal Balance. Notwithstanding the foregoing, in the event that requiring the Mortgagor to pay for the items specified
in clauses (ii), (iv) and (v) in the preceding sentence would be inconsistent with the related Mortgage
Loan documents, such reasonable costs shall be paid by the related Mortgage Loan Seller as and to the extent set forth in the
applicable Mortgage Loan Purchase Agreement.

 

(i)          
Notwithstanding anything herein or in the related Mortgage Loan documents and, if applicable, Companion Loan documents, to the
contrary, the Master Servicer may permit the substitution of “government securities,” within the meaning of Section 2(a)(16)
of the Investment Company Act of 1940, that comply with Treasury Regulations Section 1.860G-2(a)(8)(ii) for any Mortgaged
Property pursuant to the defeasance provisions of any Mortgage Loan or a Serviced Whole Loan, as applicable (or any portion thereof),
in lieu of the defeasance collateral specified in the related Mortgage Loan documents or Serviced Whole Loan documents, as applicable;
provided that such substitution is consistent with the Servicing Standard and the Master Servicer (subject to the Special
Servicer’s processing and/or consent rights pursuant to Section 3.18(a) with respect to any such action that
constitutes a Major Decision or Special Servicer Decision) reasonably determines that allowing their use would not cause a default
or event of default to become reasonably foreseeable and the Master Servicer receives an Opinion of Counsel (at the expense of
the Mortgagor to the extent permitted under the Mortgage Loan documents and, if applicable, Companion Loan documents or otherwise
as a

 

    -275-

     

    

 

Trust Fund expense) to the effect that such use would not be and would not constitute a “significant modification”
of such Mortgage Loan or Companion Loan pursuant to Treasury Regulations Section 1.860G-2(b) and would not otherwise constitute
an Adverse REMIC Event with respect to any Trust REMIC; and provided, further, that the requirements set forth in
Section 3.18(h) (including receipt of any Rating Agency Confirmation) are satisfied; and provided, further,
that such securities are backed by the full faith and credit of the United States government, or the Master Servicer shall obtain
Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will
not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities
(if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency
Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25). Notwithstanding
the foregoing, with respect to certain Mortgage Loans originated or acquired by BSP, Column or NREC that are subject to defeasance
and identified on Schedule 3, BSP, Column or NREC, as applicable, has transferred to a third party or has retained on behalf of
itself or its Affiliate the right to establish or designate the successor borrower and/or to purchase or cause to be purchased
the related defeasance collateral (collectively, the “Loan Seller Defeasance Rights and Obligations”). 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 the related Mortgage Loan Seller. Until such time
as the related Mortgage Loan Seller provides written notice to the contrary, notice of a defeasance of a Mortgage Loan with Loan
Seller Defeasance Rights and Obligations shall be delivered to the related Mortgage Loan Seller, as applicable, pursuant to the
notice provisions hereof. If the successor borrower is not designated or formed by BSP or Column, as the case may be, or any Affiliate
or successor thereto, the successor borrower shall be reasonably acceptable to the Master Servicer in accordance with the Servicing
Standard.

 

(j)      
     If required under the related Mortgage Loan or Companion Loan documents or if otherwise consistent
with the Servicing Standard, the Master Servicer shall establish and maintain one or more accounts (the “Defeasance
Accounts”), which shall be Eligible Accounts, into which all payments received by the Master Servicer from any
defeasance collateral substituted for any Mortgaged Property shall be deposited and retained, and shall administer such
Defeasance Accounts in accordance with the Mortgage Loan or Companion Loan documents. Notwithstanding the foregoing, in no
event shall the Master Servicer permit such amounts to be maintained in the Defeasance Account for a period in excess of
ninety (90) days, unless such amounts are reinvested by the Master Servicer in “government securities,” within
the meaning of Section 2(a)(16) of the Investment Company Act of 1940, that comply with Treasury Regulations
Section 1.860G-2(a)(8)(ii). To the extent not required or permitted to be placed in a separate account, the Master
Servicer shall deposit all payments received by it from defeasance collateral substituted for any Mortgaged Property into the
Collection Account and treat any such payments as payments made on the Mortgage Loan or Companion Loan in advance of its Due
Date in accordance with clause (a)(i) of the definition of “Available Funds”, and not as a prepayment
of the related Mortgage Loan or Companion Loan. Notwithstanding anything herein to the contrary, in no event shall the Master
Servicer permit such amounts to be maintained in the Collection Account for a period in excess of 365 days (or 366 days in
the case of a leap year).

 

    -276-

     

    

 

(k)          Notwithstanding anything to the contrary in this Agreement, neither the Master Servicer nor the Special Servicer, as applicable,
shall, unless it has received Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced
Companion Loan Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same
manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25)
(the cost of which shall be paid by the related Mortgagor, if so allowed by the terms of the related loan documents and otherwise
paid out of general collections) grant or accept any consent, approval or direction regarding the termination of the related property
manager or the designation of any replacement property manager, with respect to any Mortgaged Property that secures a Mortgage
Loan that (i) is one of the ten largest Mortgage Loans by Stated Principal Balance or (ii) has an unpaid principal balance
that is at least equal to five percent (5%) of the then aggregate principal balance of all Mortgage Loans or $35,000,000.

 

(l)          
Notwithstanding anything to the contrary in this Agreement, in connection with any modification, waiver, consent or amendment
in connection with any defeasance transaction contemplated clause (d) of the definition of “Special Servicer Decision”,
the Special Servicer shall not approve any such modification, waiver or amendment or consent thereto without first having received
a copy of an Opinion of Counsel addressed to the Special Servicer and the Master Servicer that such modification, waiver, consent
or amendment will not cause an Adverse REMIC Event.

 

Section 3.19     Transfer of Servicing Between Master Servicer and Special Servicer; Recordkeeping; Asset Status Report. (a)  Upon
determining that a Servicing Transfer Event has occurred with respect to any Mortgage Loan (other than any Non-Serviced Mortgage
Loan) or Serviced Companion Loan, the Master Servicer or the Special Servicer, as applicable, shall promptly give notice to the
Master Servicer or the Special Servicer, as applicable, the Operating Advisor and the Directing Holder (in the case of the Directing
Holder, (i) prior to the occurrence and continuance of a Consultation Termination Event and (ii) other than with respect to any
Excluded Loan as to such party) thereof, and the Master Servicer shall deliver the related Mortgage File and Servicing File to
the Special Servicer and concurrently provide a copy of such Servicing File, exclusive of all Privileged Communications, to the
Operating Advisor. The Master Servicer shall use its reasonable efforts to provide the Special Servicer with all information,
documents and records (including records stored electronically on computer tapes, magnetic discs and the like) relating to such
Mortgage Loan and, if applicable, the related Serviced Companion Loan, either in the Master Servicer’s possession or otherwise
available to the Master Servicer without undue burden or expense, and reasonably requested by the Special Servicer to enable it
to assume its functions hereunder with respect thereto. The Master Servicer shall use its reasonable efforts to comply with the
preceding sentence within five (5) Business Days of the occurrence of each related Servicing Transfer Event (or, in the case of
clauses (viii), (ix) or (x) of the definition of Servicing Transfer Event, within five (5) Business Days of receiving notice
from the Special Servicer of such Servicing Transfer Event when the Special Servicer makes the determination) and in any event
shall continue to act as Master Servicer and administrator of such Mortgage Loan and, if applicable, the related Serviced Companion
Loan until the Special Servicer has commenced the servicing of such Mortgage Loan and, if applicable, the related Serviced Companion
Loan. The Master Servicer shall deliver to the

 

    -277-

     

    

 

Trustee, the Certificate Administrator, the Operating Advisor, the Directing Holder
(other than with respect to any Excluded Loan as to such party and with respect to the Directing Certificateholder, prior to the
occurrence and continuance of a Consultation Termination Event), a copy of the notice of such Servicing Transfer Event provided
by the Master Servicer to the Special Servicer, or by the Special Servicer to the Master Servicer, pursuant to this Section 3.19.
Prior to the occurrence and continuance of a Consultation Termination Event, the Certificate Administrator shall deliver to each
Controlling Class Certificateholder a copy of the notice of such Servicing Transfer Event provided by the Master Servicer pursuant
to this Section 3.19.

 

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

 

(b)         
In servicing any Specially Serviced Loans and Serviced Companion Loans, the Special Servicer will provide to the Custodian originals
of documents included within the definition of “Mortgage File” for inclusion in the related Mortgage File to the extent
within its possession (with a copy of each such original to the Master Servicer), and provide the Master Servicer with copies
of any additional related Mortgage Loan or Serviced Companion Loan information including correspondence with the related Mortgagor.

 

(c)         
Notwithstanding the provisions of Section 3.12(c), the Master Servicer shall maintain ongoing payment records with
respect to each of the Specially Serviced Loans, Serviced Companion Loans and REO Properties (other than with respect to a Non-Serviced
Mortgage Loan) and shall provide the Special Servicer with any information in its possession with respect to such records to enable
the Special Servicer to perform its duties under this Agreement; provided that this statement shall not be construed to
require the Master Servicer to produce any additional reports.

 

(d)         
No later than (i) sixty (60) days after a Servicing Transfer Event for a Mortgage Loan (other than a Non-Serviced Mortgage Loan)
and, if applicable, any related Companion Loan (in the event any Serviced Whole Loan becomes a Specially Serviced Loan) and (ii)
prior to taking action with respect to any Major Decision (or making a determination not to take action with respect to a Major
Decision) with respect to a Specially Serviced Loan, the Special Servicer shall deliver in electronic format a report (the “Asset
Status Report”) with

 

    -278-

     

    

 

respect to such Mortgage Loan and related Companion Loan and the related Mortgaged Property (the
“Initial Delivery Date”) and will be required to prepare one or more additional Asset Status Reports with respect
to any such Specially Serviced Loan subsequent to the issuance of a Final Asset Status Report to the extent that during the course
of the resolution of such Specially Serviced Loan material changes in the strategy reflected in the initial Final Asset Status
Report (or subsequent Final Asset Status Report) are necessary to reflect the then current recommendation as to how the Specially
Serviced Loan might be returned to performing status or otherwise liquidated in accordance with the Servicing Standard (each such
report a “Subsequent Asset Status Report”). Each Asset Status Report shall be delivered in electronic form
to the Master Servicer, the Directing Holder (but only with respect to any Mortgage Loan other than an Excluded Loan as to such
party and prior to the occurrence and during the continuance of a Consultation Termination Event), the Risk Retention Consultation
Party (but only with respect to any Mortgage Loan other than an Excluded Loan as to such party), the Operating Advisor (but, (i)
other than with respect to an Excluded Loan, only after the occurrence and continuance of an Operating Advisor Consultation Event
and (ii) with respect to the Allergan HQ Whole Loan, the JW Marriott Chicago Whole Loan or the Center 78 Whole Loan only to the
extent it is also subject to a Control Appraisal Period under the related Intercreditor Agreement), and the 17g-5 Information
Provider (which shall promptly post such report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c))
and, with respect to any related Serviced Companion Loan, to the extent the related Serviced Companion Loan has been included
in an Other Securitization, to the master servicer of such Other Securitization into which the related Serviced Companion Loan
has been sold or to the related Companion Holder. The Special Servicer shall notify the Operating Advisor of whether any Asset
Status Report delivered to the Operating Advisor is a Final Asset Status Report, which notification may be satisfied by (i) delivery
of an Asset Status Report that is either signed by the Directing Holder or that otherwise includes an indication that such Asset
Status Report is deemed approved due to the passage of any required consent or consultation time period or (ii) such other method
as reasonably agreed to by the Operating Advisor and the Special Servicer. Such Asset Status Report shall set forth the following
information to the extent reasonably determinable based on the information that was delivered to the Special Servicer in connection
with the transfer of servicing pursuant to the Servicing Transfer Event:

 

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

 

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

 

(iii)          the most current rent roll (or, with respect to any residential cooperative property, the most current maintenance schedule) and
income or operating statement available for the related Mortgaged Property;

 

(iv)          (A) the Special Servicer’s recommendations on how such Specially Serviced Loan might be returned to performing status (including
the modification of a

 

    -279-

     

    

 

monetary term, and any workout, restructure or debt forgiveness) and returned to the Master Servicer for
regular servicing or otherwise realized upon (including any proposed sale of a Defaulted Loan or REO Property), (B) a description
of any such proposed or taken actions, and (C) the alternative courses of action that were or are being considered by the Special
Servicer in connection with the proposed or taken actions;

 

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

 

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

 

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

 

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

 

(ix)          the appraised value of the related Mortgaged Property (and a copy of the last obtained Appraisal of such Mortgaged Property) together
with a description of any adjustments to the valuation of such Mortgaged Property made by the Special Servicer together with an
explanation of those adjustments; and

 

(x)           such other information as the Special Servicer deems relevant in light of the Servicing Standard.

 

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

 

If
within ten (10) Business Days (or, in the case of an Asset Status Report prepared prior to making a determination of an Acceptable
Insurance Default, 10 days) of receiving an Asset Status Report, the Directing Holder does not disapprove such Asset Status Report
in writing (or, in the case of an Asset Status Report prepared prior to making a determination of an Acceptable Insurance Default,
10 days), or if the Special Servicer makes a determination, in accordance with the Servicing Standard that the disapproval by
the Directing Holder (communicated to the Special Servicer within ten (10) Business Days) is not in the best interest of all the
Certificateholders), the Special Servicer shall implement the recommended action as outlined in such Asset Status Report; provided,
however, that the Special Servicer may not take any action that is contrary to applicable law, the Servicing Standard or
the terms of the applicable Mortgage Loan documents. If, with respect to any Mortgage Loan other than an Excluded Loan with respect
to the Directing Holder or the Holder of the majority of the Controlling Class prior to the occurrence and continuance of any
Control Termination Event, the

 

    -280-

     

    

 

Directing Holder disapproves such Asset Status Report within ten (10) Business Days (or, in the
case of an Asset Status Report prepared prior to making a determination of an Acceptable Insurance Default, 10 days) of receipt
and the Special Servicer has not made the affirmative determination described above, the Special Servicer shall revise such Asset
Status Report and deliver a new Asset Status Report as soon as practicable, but in no event later than thirty (30) days after
such disapproval, to the Master Servicer, the Directing Holder (prior to the occurrence and continuance of a Consultation Termination
Event and other than if an Excluded Loan as to such party is involved), the Operating Advisor (but only after the occurrence and
during the continuance of an Operating Advisor Consultation Event) and the 17g-5 Information Provider (which shall promptly post
such report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)) and, in the case
of a Serviced Whole Loan, the related Serviced Companion Noteholder; provided, however, that, if the Special Servicer
determines that emergency action is necessary to protect the related Mortgaged Property or the interests of the Certificateholders
and any related Serviced Companion Noteholder, or if a failure to take any such action at such time would be inconsistent with
the Servicing Standard, the Special Servicer may take actions with respect to the related Mortgaged Property before the expiration
of the ten (10) Business Day period (or, in the case of an Asset Status Report prepared prior to making a determination of an
Acceptable Insurance Default, 10 days period) if the Special Servicer reasonably determines in accordance with the Servicing Standard
that failure to take such actions before the expiration of the ten (10) Business Day period (or, in the case of an Asset Status
Report prepared prior to making a determination of an Acceptable Insurance Default, 10 days Business Day period) would materially
and adversely affect the interest of the Certificateholders and the related Serviced Companion Noteholder (if applicable) and
the Special Servicer has made a reasonable effort, prior to the occurrence and continuance of any Control Termination Event and
other than if an Excluded Loan is involved, to contact the Directing Certificateholder. With respect to any Mortgage Loan other
than an Excluded Loan with respect to the Directing Holder or the Holder of the majority of the Controlling Class, prior to the
occurrence and continuance of any Control Termination Event, the Special Servicer shall revise such Asset Status Report as described
above in this Section 3.19(d) until the Directing Holder shall fail to disapprove such revised Asset Status Report
in writing within ten (10) Business Days or, in the case of an Asset Status Report prepared prior to making a determination of
an Acceptable Insurance Default, 10 days) of receiving such revised Asset Status Report or until the Special Servicer makes a
determination, in accordance with the Servicing Standard, that the disapproval is not in the best interests of the Certificateholders;
provided that, if the Directing Holder has not approved the Asset Status Report for a period of sixty (60) Business Days
following the first submission of an Asset Status Report, the Special Servicer may act upon the most recently submitted form of
Asset Status Report, if consistent with the Servicing Standard; provided, however, that such Asset Status Report
does not, and is not intended to be, a substitute for the approvals that are specifically required pursuant to Section 6.08.
The procedures described in this paragraph are collectively referred to as the “Directing Holder Approval Process”.
The Special Servicer may, from time to time, modify any Asset Status Report it has previously delivered and implement such report;
provided that such report shall have been prepared, reviewed and not rejected pursuant to the terms of this Section 3.19(d).
Notwithstanding anything herein to the contrary, with respect to any Excluded Loan with respect to the Directing Holder or the
Holder of the majority of the Controlling Class (regardless of whether an Operating Advisor Consultation Event has occurred and
is continuing), the Special Servicer shall

 

    -281-

     

    

 

consult with the Operating Advisor (telephonically or electronically), on a non-binding
basis, in connection with an Asset Status Report for an Excluded Loan with respect to the Directing Holder or the Holder of the
majority of the Controlling Class that includes a Major Decision that it is processing or for which its consent is required and
consider alternative actions recommended by the Operating Advisor, in respect thereof, in accordance with the procedures set forth
in Section 6.08 for consulting with the Operating Advisor.

 

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

 

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

 

During
the continuance of an Operating Advisor Consultation Event, the Operating Advisor shall provide comments to the Special Servicer
in respect of the applicable Asset Status Report, if any, within ten (10) Business Days following the later of (i) receipt
of such Asset Status Report or (ii) receipt of such additional information reasonably requested by the Operating Advisor
related thereto, and propose possible alternative courses of action to the extent it determines such alternatives to be in the
best interest of the Certificateholders (including any Certificateholders that are holders of the Controlling Class Certificates),
as a collective whole. The Special Servicer shall consider such alternative courses of action, if any, and any other feedback
provided by the Operating Advisor (and for so long as no Consultation Termination Event is continuing, the Directing Holder) in
connection with the Special Servicer’s preparation of any Asset Status Report that is provided while an Operating Advisor
Consultation Event has occurred and is continuing. The Special Servicer may revise the Asset Status Report as it deems necessary
to take into account any input and/or comments from the Operating Advisor (and for so long as no Consultation Termination Event
is continuing, the Directing Holder), to the extent the Special Servicer determines that the Operating Advisor’s and/or
Directing Holder’s input and/or recommendations are consistent with the Servicing Standard and in the best interest of the
Certificateholders as a collective whole (or, with respect to a Serviced Whole Loan, the best interest of the Certificateholders
and the holders of the related Companion Loan(s), as a collective whole (taking into account the pari passu or subordinate
nature of each 

 

    -282-

     

    

 

such Companion Loan)). Promptly upon determining whether or not to revise any Asset Status Report to take into
account any input and/or comments from the Operating Advisor or the Directing Holder, the Special Servicer shall deliver to the
Operating Advisor and the Directing Holder the revised Asset Status Report (until a Final Asset Status Report is issued). The
procedures described in this paragraph are collectively referred to as the “ASR Consultation Process”.

 

After
the occurrence and during the continuance of a Control Termination Event (and at any time with respect to any Excluded Loan with
respect to such party or the Holder of the majority of the Controlling Class), the Directing Holder shall have no right to consent
to any Asset Status Report under this Section 3.19. After the occurrence and during the continuance of a Control Termination
Event but prior to the occurrence and continuance of a Consultation Termination Event, the Special Servicer shall send the Directing
Holder (except with respect to any Excluded Loan as to such party), and, after the occurrence and during the continuance of an
Operating Advisor Consultation Event, the Operating Advisor, the Asset Status Report and the Operating Advisor and the Directing
Holder shall consult with the Special Servicer (telephonically or electronically) and propose alternative courses of action and
provide other feedback in respect of any Asset Status Report. The Directing Holder (or, if the Directing Holder is the Directing
Certificateholder, other than in its capacity as a Certificateholder) (in each case, after the occurrence and during the continuance
of a Consultation Termination Event (and at any time with respect to any Excluded Loan as to such party)), shall have no right
to receive any Asset Status Report or otherwise consult with the Special Servicer with respect to Asset Status Reports and the
Special Servicer shall only be obligated to consult with the Operating Advisor with respect to any Asset Status Report as described
above. The Special Servicer may choose to revise the Asset Status Report as it deems reasonably necessary in accordance with the
Servicing Standard to take into account any input and/or recommendations of the Operating Advisor or the Directing Holder during
the applicable periods described above, but is under no obligation to follow any particular recommendation of the Operating Advisor
or the Directing Holder.

 

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

 

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

 

Notwithstanding
the foregoing, the Special Servicer shall not be permitted to follow any advice, direction or consultation provided by the Operating
Advisor, any Serviced Companion Noteholder (or its representative) or the Directing Certificateholder that would require or cause
the Special Servicer to violate any applicable law, be inconsistent with the Servicing Standard or any Intercreditor Agreement,
require or cause the Special Servicer to violate provisions of this Agreement, require or cause the Special Servicer to violate
the terms of any Intercreditor Agreement or any Mortgage Loan or Serviced Whole Loan, expose any Certificateholder or any party
to this Agreement or their affiliates, officers, directors or agents to any claim, suit or liability, cause any Trust REMIC to
fail to qualify as a REMIC for federal

 

    -283-

     

    

 

 income tax purposes or result in the imposition of “prohibited transaction”
or “prohibited contribution” tax under the REMIC Provisions, or materially expand the scope of the Special Servicer’s
responsibilities under this Agreement or any Intercreditor Agreement.

 

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

 

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

 

(f)           Prior to the occurrence and continuance of a Control Termination Event, no later than two (2) Business Days following the establishment
of a Final Asset Status Report with respect to any Specially Serviced Loan (other than any Excluded Loan), the Special Servicer
shall deliver in electronic format to the Directing Certificateholder (other than with respect to any Excluded Loan as to such
party) a draft notice that will include a draft summary of the Final Asset Status Report (which briefly summarizes such Final
Asset Status Report, but shall not include any Privileged Information) (and shall deliver each Asset Status Report with respect
to a Serviced AB Whole Loan prior to the occurrence and continuance of an AB Control Appraisal Period (to the extent approved
by the related AB Whole Loan Controlling Holder)). With respect to any Mortgage Loan other than an Excluded Loan with respect
to the Directing Certificateholder or the Holder of the majority of the Controlling Class, if, prior to the occurrence and continuance
of a Control Termination Event, within five (5) Business Days of receipt of such draft summary, the Directing Certificateholder
approves of, or does not disapprove of such draft summary, then the Special Servicer shall deliver in electronic format such notice
and summary of the Final Asset Status Report to the Certificate Administrator for posting on the Certificate Administrator’s
Website pursuant to Section 3.13(b). If the Directing Certificateholder affirmatively disapproves of such summary
in writing, then within two (2) Business Days of receipt of such disapproval, the Special Servicer shall revise the summary and
deliver such new summary to the Directing Certificateholder until the Directing Certificateholder approves such draft summary;
provided, however, that if the Directing Certificateholder has not approved of the draft summary of the Final Asset
Status Report within twenty (20) Business Days of receipt of the initial draft summary of the Final Asset Status Report, then
the most recent draft summary of the Final Asset Status Report delivered by the Special Servicer prior to such 20th Business Day
shall be deemed to be the final summary of the Final Asset Status Report; provided, further, however, that
if at any time the Special Servicer determines that any affirmative disapproval of such draft summary by the Directing Certificateholder
is not in the best interest of all the Certificateholders pursuant to the Servicing Standard, the Special Servicer shall deliver
in electronic format such notice and summary of the Final Asset Status Report to the

 

    -284-

     

    

 

Certificate Administrator for posting on
the Certificate Administrator’s Website pursuant to Section 3.13(b) notwithstanding such disapproval. The Special
Servicer shall promptly deliver (but in any event no later than two (2) Business Days following its completion) a copy of each
Final Asset Status Report to the Operating Advisor. The Special Servicer shall prepare a summary of any Final Asset Status Report
related to any Serviced AB Whole Loan for which the related holder of an AB Subordinate Companion Loan is not subject to an AB
Control Appraisal Period, which Final Asset Status Report has been approved or deemed approved by the holder of the related AB
Subordinate Companion Loan in accordance with the related Co-Lender Agreement (to the extent such Co-Lender Agreement requires
such approval or deemed approval), and deliver in electronic format notice of such Final Asset Status Report and the summary of
such Final Asset Status Report to the Certificate Administrator for posting on the Certificate Administrator’s Website pursuant
to Section 3.13(b).

 

(g)          
No provision of this Section 3.19 shall require the Special Servicer to take or to refrain from taking any action
because of any proposal, objection or comment by the Operating Advisor or, after the occurrence and during the continuance of
a Control Termination Event, the Directing Holder or a recommendation of the Operating Advisor or, after the occurrence and during
the continuance of a Control Termination Event, or the Directing Holder.

 

Section 3.20     Sub-Servicing
Agreements. (a)  The Master Servicer and the Special Servicer may enter into Sub-Servicing Agreements to
provide for the performance by third parties of any or all of its respective obligations hereunder; provided that the
Sub-Servicing Agreement as amended or modified: (i) is consistent with this Agreement in all material respects and
requires the Sub-Servicer to comply with all of the applicable conditions of this Agreement; (ii) provides that if the
Master Servicer or the Special Servicer, as applicable, shall for any reason no longer act in such capacity hereunder
(including, without limitation, by reason of a Servicer Termination Event), the Trustee or its designee shall thereupon
assume all of the rights and, except to the extent they arose prior to the date of assumption, obligations of such party
under such agreement, or, alternatively, may act in accordance with Section 7.02 hereof under the circumstances
described therein (subject to Section 3.20(g) hereof); (iii) provides that the Trustee (for the benefit of
the Certificateholders and the related Companion Holder (if applicable) and the Trustee (as holder of the Lower-Tier Regular
Interests) shall be a third party beneficiary under such Sub-Servicing Agreement, but that (except to the extent the Trustee
or its designee assumes the obligations of such party thereunder as contemplated by the immediately preceding clause (ii))
none of the Trust, the Trustee, the Operating Advisor, the Asset Representations Reviewer, the Certificate Administrator, the
Master Servicer or the Special Servicer, as applicable, any successor master servicer or special servicer or any
Certificateholder (or the related Companion Holder, if applicable) shall have any duties under such Sub-Servicing Agreement
or any liabilities arising therefrom; (iv) permits any purchaser of a Mortgage Loan pursuant to this Agreement to
terminate such Sub-Servicing Agreement with respect to such purchased Mortgage Loan at its option and without
penalty; provided, however, that the Initial Sub-Servicing Agreements may only be terminated by the Trustee or
its designees as contemplated by Section 3.20(g) hereof and in such additional manner and by such other Persons
as is provided in such Sub-Servicing Agreement; (v) does not permit the Sub-Servicer any direct rights of
indemnification that may be satisfied out of assets of the Trust; (vi) does not permit the Sub-Servicer to modify any
Mortgage Loan unless and to the extent the Master Servicer or the Special Servicer, as applicable, is permitted hereunder to
modify such Mortgage Loan; (vii) with

 

    -285-

     

    

 

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 (viii) provides that the Sub-Servicer shall be in default under the related Sub-Servicing
Agreement and such Sub-Servicing Agreement shall be terminated (following the expiration of any applicable Grace Period) if the
Sub-Servicer fails (A) to deliver by the due date any Exchange Act reporting items required to be delivered to the Master
Servicer, Certificate Administrator or Depositor under Article XI or under the Sub-Servicing Agreement or to the master
servicer under any other pooling and servicing agreement that the Depositor is a party to, or (B) to perform in any material
respect any of its covenants or obligations contained in the Sub-Servicing Agreement regarding creating, obtaining or delivering
any Exchange Act reporting items required for any party to this Agreement to perform its obligations under Article XI
 or under the Exchange Act reporting items required under any other pooling and servicing agreement that the Depositor is a
party to. Any successor master servicer or special servicer, as applicable, hereunder shall, upon becoming successor master servicer
or special servicer, as applicable, be assigned and may assume any Sub-Servicing Agreements from the predecessor Master Servicer
or the Special Servicer, as applicable (subject to Section 3.20(g) hereof). In addition, each Sub-Servicing Agreement
entered into by the Master Servicer may but need not provide that the obligations of the Sub-Servicer thereunder may terminate
with respect to any Mortgage Loan serviced thereunder at the time such Mortgage Loan becomes a Specially Serviced Loan; provided,
however, that the Sub-Servicing Agreement may provide (if the Sub-Servicing Agreement provides for Advances by the Sub-Servicer,
although it need not so provide) that the Sub-Servicer will continue to make all Advances and calculations and prepare all reports
required under the Sub-Servicing Agreement with respect to Specially Serviced Loans and continue to collect its Primary Servicing
Fees as if no Servicing Transfer Event had occurred and with respect to REO Properties (and the related REO Loans) as if no REO
Acquisition had occurred and to render such incidental services with respect to such Specially Serviced Loans and REO Properties
as are specifically provided for in such Sub-Servicing Agreement. The Master Servicer or the Special Servicer, as applicable,
shall deliver to the Trustee (i) copies of all Sub-Servicing Agreements entered into by it, in each case, promptly upon its
execution and delivery of such documents and (ii) upon request of the Trustee, any amendments or modifications to such Sub-Servicing
Agreements. References in this Agreement to actions taken or to be taken by the Master Servicer include actions taken or to be
taken by a Sub-Servicer on behalf of the Master Servicer; and, in connection therewith, all amounts advanced by any Sub-Servicer
(if the Sub-Servicing Agreement provides for Advances by the Sub-Servicer, although it need not so provide) to satisfy the obligations
of the Master Servicer hereunder to make Advances shall be deemed to have been advanced by the Master Servicer out of its own
funds and, accordingly, in such event, such Advances shall be recoverable by such Sub-Servicer in the same manner and out of the
same funds as if such Sub-Servicer were the Master Servicer, and, for so long as they are outstanding, such Advances shall accrue
interest in accordance with Section 3.03(d), such interest to be allocable between the Master Servicer and such Sub-Servicer
as may be provided (if at all) pursuant to the terms of the Sub-Servicing Agreement. For purposes of this Agreement, the Master
Servicer shall be deemed to have received any payment when a Sub-Servicer retained by it receives such payment. The Master Servicer
or the Special Servicer, as applicable, shall notify the Master Servicer or the Special Servicer, as applicable, the Trustee and
the Depositor (and the Special Servicer shall notify the Operating Advisor) in

 

    -286-

     

    

 

writing promptly of the appointment by it of any
Sub-Servicer, except that the Master Servicer need not provide such notice as to the Initial Sub-Servicing Agreements.

 

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

 

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

 

(d)          In the event the Trustee or its designee becomes successor master servicer and assumes the rights and obligations of the Master
Servicer under any Sub-Servicing Agreement, the Master Servicer, at its expense, shall deliver to the assuming party all documents
and records relating to such Sub-Servicing Agreement and the Mortgage Loans and, if applicable, the Companion Loans then being
serviced thereunder and an accounting of amounts collected and held on behalf of it thereunder, and otherwise use reasonable efforts
to effect the orderly and efficient transfer of the Sub-Servicing Agreement to the assuming party.

 

(e)          Notwithstanding the provisions of any Sub-Servicing Agreement and this Section 3.20, except to the extent provided
in Article XI with respect to the obligations of any Sub-Servicer that is an Initial Sub-Servicer, the Master Servicer
or the Special Servicer, as applicable, shall remain obligated and responsible to the Trustee, the Master Servicer, the Special
Servicer, holders of the Companion Loans serviced hereunder and the Certificateholders for the performance of its obligations
and duties under this Agreement in accordance with the provisions hereof to the same extent and under the same terms and conditions
as if it alone were servicing and administering the Mortgage Loans for which it is responsible, and the Master Servicer or the
Special Servicer, as applicable, shall pay the fees of any Sub-Servicer thereunder as and when due from its own funds. In no event
shall the Trust bear any termination fee required to be paid to any Sub-Servicer as a result of such Sub-Servicer’s termination
under any Sub-Servicing Agreement.

 

(f)           The Trustee, upon the request of the Master Servicer or the Special Servicer, as applicable, shall furnish to any Sub-Servicer
any documents necessary or appropriate to enable such Sub-Servicer to carry out its servicing and administrative duties under
any Sub-Servicing Agreement.

 

    -287-

     

    

 

(g)          Each Sub-Servicing Agreement shall provide that, in the event the Trustee or any other Person becomes successor master servicer,
the Trustee or such successor master servicer shall have the right to terminate such Sub-Servicing Agreement with or without cause
and without a fee. Notwithstanding the foregoing or any other contrary provision in this Agreement, the Trustee and any successor
master servicer shall assume each Initial Sub-Servicing Agreement and (i) the Initial Sub-Servicer’s rights and obligations
under the Initial Sub-Servicing Agreement shall expressly survive a termination of the Master Servicer’s servicing rights
under this Agreement; provided that the Initial Sub-Servicing Agreement has not been terminated in accordance with its
provisions; (ii) any successor master servicer, including, without limitation, the Trustee (if it assumes the servicing obligations
of the Master Servicer) shall be deemed to automatically assume and agree to the then-current Initial Sub-Servicing Agreement
without further action upon becoming the successor master servicer and (iii) this Agreement may not be modified in any manner
which would increase the obligations or limit the rights of the Initial Sub-Servicer hereunder and/or under the Initial Sub-Servicing
Agreement, without the prior written consent of the Initial Sub-Servicer (which consent shall not be unreasonably withheld).

 

(h)          With respect to Mortgage Loans subject to a Sub-Servicing Agreement with the Master Servicer, the Special Servicer shall, upon
request (such request to be made reasonably in advance as appropriate to the circumstances surrounding such request) of the related
Sub-Servicer, reasonably cooperate in delivering reports and information, including remittance information, and affording access
to information to the related Sub-Servicer that would be required to be delivered or afforded, as the case may be, to the Master
Servicer pursuant to the terms hereof.

 

(i)          
 Notwithstanding any other provision of this Agreement, the Special Servicer shall not enter into any Sub-Servicing Agreement that
provides for the performance by third parties of any or all of its obligations herein, without, prior to the occurrence and continuance
of any Control Termination Event and other than with respect to any Mortgage Loan that is an Excluded Loan with respect to the
Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling
Class, the consent of the Directing Holder, except to the extent necessary for the Special Servicer to comply with applicable
regulatory requirements.

 

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

(a)  On
the P&I Advance Date occurring in January (except during a leap year) and February of each calendar year commencing in 2017
(in each case, unless the related Distribution Date is the final Distribution Date), the Certificate Administrator, in respect

    -288-

     

    

 

immediately following the Distribution Date occurring in the
month preceding the month in which P&I Advance Date occurs at the related Net Mortgage Rate, to the extent a full Periodic
Payment or P&I Advance is made in respect thereof (all amounts so deposited pursuant to this sentence in any particular January
and/or February, “Withheld Amounts”).

 

(b)          
On each P&I Advance Date occurring in March (or February, if the related Distribution Date is the final Distribution Date),

Section 3.22     Directing Holder and Operating Advisor Contact with the Master Servicer and the Special Servicer. Within a reasonable time
upon request from the Directing Holder or the Operating Advisor, as applicable, and no more often than on a monthly basis, each
of the Master Servicer and the Special Servicer shall, without charge, make a knowledgeable Servicing Officer via telephone available
to verbally answer questions from (a) the Directing Holder ((i) prior to the occurrence and continuance of a Consultation
Termination Event and (ii) other than with respect to any Excluded Loan as to such party) and (b) the Operating Advisor (with
respect to the Special Servicer only), regarding the performance and servicing of the Mortgage Loans and/or REO Properties for
which the Master Servicer or the Special Servicer, as the case may be, is responsible.

 

Section 3.23     Controlling Class Certificateholders, Directing Certificateholder and the Risk Retention Consultation Party; Certain Rights
and Powers of Directing Holder and the Risk Retention Consultation Party. (a)  Each Controlling Class Certificateholder
is hereby deemed to have agreed by virtue of its purchase of a Certificate to provide its name and address to the Certificate
Administrator and to notify the Master Servicer, the Certificate Administrator, the Special Servicer and the Operating Advisor
of the transfer of any Certificate of a Controlling Class by delivering a notice to each such Person substantially in the form
of Exhibit NN attached hereto, the selection of a Directing Certificateholder or the resignation or removal thereof.
The Directing Certificateholder is hereby deemed to have agreed by virtue of its purchase of a Certificate to notify the Master
Servicer, the Special Servicer, the Certificate Administrator, the Trustee and the Operating Advisor when such Certificateholder
is appointed Directing Certificateholder and when it is removed or resigns. To the extent there is only one Controlling Class
Certificateholder and it is also the Special Servicer, it shall be the Directing Certificateholder.

 

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

 

On
the Closing Date, the initial Risk Retention Consultation Party shall deliver to the parties to this Agreement a certification
substantially in the form of Exhibit P-1H to this Agreement. Upon the resignation or removal of the existing Risk
Retention Consultation Party,

 

    -289-

     

    

 

any successor risk retention consultation party shall execute and also deliver to the parties to
this Agreement a certification substantially in the form of Exhibit P-1H to this Agreement prior to being recognized
as the new Risk Retention Consultation Party.

 

(b)          
Once a Directing Certificateholder has been selected, each of the Master Servicer, the Special Servicer, the Depositor, the Trustee,
the Certificate Administrator, the Operating Advisor and each other Certificateholder (or Certificate Owner, if applicable) shall
be entitled to rely on such selection unless the Controlling Class Certificateholders entitled to appoint the Directing Certificateholder,
by Certificate Balance, or such Directing Certificateholder shall have notified the Master Servicer, the Special Servicer, the
Trustee, the Certificate Administrator, the Operating Advisor and each other Controlling Class Certificateholder, in writing,
of the resignation of such Directing Certificateholder or the selection of a new Directing Certificateholder. Upon the resignation
of a Directing Certificateholder, the Certificate Administrator shall request the Controlling Class Certificateholders to select
a new Directing Certificateholder. In the event that (i) the Master Servicer, the Certificate Administrator, the Special
Servicer, the Trustee or the Operating Advisor receives written notice from a majority of the Controlling Class Certificateholders
that a Directing Certificateholder is no longer designated and (ii) the Controlling Class Certificateholder that owns the
largest aggregate Certificate Balance of the Controlling Class (or a representative thereof) becomes the Directing Certificateholder
pursuant to the proviso of the definition of “Directing Certificateholder”, then the Controlling Class Certificateholder
that owns the largest aggregate Certificate Balance of the Controlling Class (or its representative) shall provide its name and
address to the Certificate Administrator and notify the Master Servicer, the Certificate Administrator, the Special Servicer,
the Trustee and the Operating Advisor that it is the new Directing Certificateholder; provided that the Master Servicer,
the Certificate Administrator, the Special Servicer, the Trustee and the Operating Advisor shall be entitled to rely on the written
notification provided by the purported Controlling Class Certificateholder that owns the largest aggregate Certificate Balance
of the Controlling Class without independently verifying that such Controlling Class Certificateholder actually owns the largest
aggregate Certificate Balance of the Controlling Class. Additionally, once a Risk Retention Consultation Party has been selected,
each of the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor
and each other Certificateholder (or Certificate Owner, if applicable) shall be entitled to rely on such selection unless the
Holders of the VRR Interest entitled to appoint the Risk Retention Consultation Party, by Certificate Balance, or such Risk Retention
Consultation Party shall have notified the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator,
the Operating Advisor and each other Holder of the VRR Interest, in writing, of the selection of a new Risk Retention Consultation
Party.

 

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

 

(d)          In the event that no Directing Holder has been appointed or identified to the Master Servicer or the Special Servicer, as applicable,
and the Master Servicer or the Special

 

    -290-

     

    

 

Servicer, as the case may be, has attempted to obtain such information from the Certificate
Administrator and no such entity has been identified to the Master Servicer or the Special Servicer, as applicable, then until
such time as the new Directing Holder is identified, the Master Servicer or the Special Servicer, as applicable, shall have no
duty to consult with, provide notice to, or seek the approval or consent of any such Directing Holder as the case may be.

 

(e)        
  Upon request, the Certificate Administrator shall deliver to the Depositor, Trustee, the Special Servicer, the
Operating Advisor, the Master Servicer and, prior to the occurrence and continuance of a Consultation Termination Event, the
Directing Certificateholder, a list of each Controlling Class Certificateholder (or each Certificate Owner of the Controlling
Class, if applicable), including names and addresses. In addition to the foregoing, within five (5) Business Days of
receiving notice of the selection of a new Directing Certificateholder or Risk Retention Consultation Party or the existence
of a new Controlling Class Certificateholder, the Certificate Administrator shall notify the Trustee, the Operating Advisor,
the Master Servicer and the Special Servicer. Notwithstanding the foregoing, (a) RREF III - D AIV RR, LLC shall be the
initial Directing Certificateholder and shall remain so until a successor is appointed pursuant to the terms of this
Agreement or until a Consultation Termination Event occurs and is continuing, and (b) NREC shall be the initial Risk
Retention Consultation Party and shall remain so until a successor is appointed pursuant to the terms of this Agreement or
until a Consultation Termination Event occurs and is continuing.

 

Until
it receives notice to the contrary, each of the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate
Administrator and the Trustee shall be entitled to rely on the preceding sentence with respect to the identity of the Directing
Certificateholder and the Risk Retention Consultation Party.

 

(f)           If to the extent the Certificate Administrator determines that a Class of Book-Entry Certificates is the Controlling Class, the
Certificate Administrator shall notify the related Certificateholders of such Class (through the Depository) of the Class becoming
the Controlling Class.

 

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

 

Each
Certificateholder acknowledges and agrees, by its acceptance of its Certificates, that: (i) the Risk Retention Consultation
Party may have special relationships and interests that conflict with those of Holders of one or more Classes of Certificates;
(ii) the Risk

 

    -291-

     

    

 

Retention Consultation Party may act solely in the interests of the Holders of the VRR Interest; (iii) the
Risk Retention Consultation Party does not have any liability or duties to the Holders of any Class of Certificates other than
the VRR Interest; (iv) the Risk Retention Consultation Party may take actions that favor interests of the Holders of one
or more Classes including the VRR Interest over the interests of the Holders of one or more other Classes of Certificates; and
(v) the Risk Retention Consultation Party shall have no liability whatsoever (other than to a Holder of an VRR Interest)
for having so acted as set forth in clauses (i) through (iv) above, and no Certificateholder may take any action
whatsoever against the Risk Retention Consultation Party or any director, officer, employee, agent or principal of the Risk Retention
Consultation Party for having so acted.

 

(h)          All requirements of the Master Servicer and the Special Servicer to provide notices, reports, statements or other information
(including the access to information on a website) to the Directing Holder contained in this Agreement shall also apply to each
Companion Holder with respect to information relating to the related Serviced Whole Loan, as applicable; provided, however,
that nothing in this subsection (h) shall in any way eliminate the obligation to deliver any information required to be
delivered under the related Intercreditor Agreement.

 

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

 

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

 

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

 

(l)          
At any time that the Controlling Class Certificateholder is the holder of a majority of the Class F Certificates and the Class
F Certificates are the Controlling Class, it may waive its right (a) to appoint the Directing Certificateholder and (b) to exercise
any of the Directing Certificateholder’s rights under this Agreement by irrevocable written notice delivered to the Depositor,
the Certificate Administrator (which shall be via email to trustadministrationgroup@wellsfargo.com .com), the Trustee, the Master
Servicer, the Special Servicer and the Operating Advisor. Notwithstanding anything to the contrary contained herein, during such
time as a Control Termination Event or Consultation Termination Event is in existence solely as a result of the operation of clause (ii) of the definition of Control Termination Event and clause (ii) of the definition of Consultation Termination Event,
such Control Termination Event or Consultation Termination Event shall be deemed to no longer be in existence and have not occurred
with respect to any unaffiliated third party to whom the

 

    -292-

     

    

 

Controlling Class Certificateholder that irrevocably waived its right
to exercise any of the rights of the Controlling Class Certificateholder has sold or transferred all or a portion of its interest
in the Class F Certificates if such unaffiliated third party holds the majority of the Controlling Class after giving effect to
such transfer (the “Non-Waiving Successor”). Following any such sale or transfer, the Non-Waiving Successor
shall again have the rights of the Controlling Class Certificateholder as set forth herein (including the rights to appoint a
Directing Certificateholder or cause the exercise of the rights of the Directing Certificateholder) without regard to any prior
waiver by the predecessor Controlling Class Certificateholder. The Non-Waiving Successor shall also have the right to exercise
any of the rights of the Controlling Class Certificateholder. No Non-Waiving Successor described above shall have any consent
rights with respect to any Mortgage Loan that became a Specially Serviced Loan prior to the sale or transfer of the Class F Certificates
to the Non-Waiving Successor and had not also become a Corrected Loan prior to such sale or transfer until such time as such Mortgage
Loan becomes a Corrected Loan.

 

(m)          Promptly upon its determination of a change in the Controlling Class, the Certificate Administrator shall (i) include on
its statement made available pursuant to Section 4.02(a) of this Agreement the identity of the new Controlling Class
and (ii) provide to the Master Servicer, the Special Servicer and the Operating Advisor notice of such event and the identity
and contact information of the new Controlling Class Certificateholder (the cost of obtaining such information from DTC being
an expense of the Trust). The Certificate Administrator shall notify the Operating Advisor, the Master Servicer and the Special
Servicer within ten (10) Business Days of the existence or cessation of (i) any Control Termination Event, (ii) any
Consultation Termination Event or (iii) any Operating Advisor Consultation Event. Upon the Certificate Administrator’s
determination that a Control Termination Event, a Consultation Termination Event or an Operating Advisor Consultation Event has
occurred or is terminated, the Certificate Administrator shall, within ten (10) Business Days, post a “special notice”
on the Certificate Administrator’s Website pursuant to this provision.

 

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

 

In
the event that a Control Termination Event or Consultation Termination Event has occurred due to the irrevocable waiver by a Class
F Certificateholder who has become the Controlling Class Certificateholder of its right to appoint a Directing Certificateholder
or to exercise any of the rights of the Controlling Class Certificateholder, such special notice shall state “A Control
Termination Event and a Consultation Termination Event has occurred due to the irrevocable waiver by the Controlling Class Certificateholder
of its rights as Controlling Class Certificateholder.”

 

In
the event that a Consultation Termination Event has occurred due to the reduction of each Class of Control Eligible Corresponding
Certificates below 25% of its Original Certificate Balance, in each case without regard to the application of any Cumulative Appraisal

 

    -293-

     

    

 

Reduction Amounts, such special notice shall state: “A Consultation Termination Event has occurred because no Class of Control
Eligible Corresponding Certificates exists where such Class’s aggregate Certificate Balance is at least equal to 25% of
the Original Certificate Balance of that Class, in each case without regard to the application of any Cumulative Appraisal Reduction
Amounts.”

 

In
the event of any transfer of a Class F Certificate, and upon notice to the Certificate Administrator in the form of Exhibit NN that results in a termination of a Control Termination Event or a Consultation Termination Event, such “special notice”
shall state: “A Consultation Termination Event or a Control Termination Event has been terminated and is no longer in effect
due to a transfer of a majority interest of the Controlling Class Certificates to an unaffiliated third party which has terminated
any waiver by the prior Holder.”

 

The
Directing Holder shall not have any consent or consultation rights with respect to any Mortgage Loan determined to be an Excluded
Loan as to either the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority
of the Controlling Class. Likewise, the Risk Retention Consultation Party shall not have any consultation rights with respect
to any Mortgage Loan determined to be an Excluded Loan as to either such Risk Retention Consultation Party or the Holder of the
majority of the VRR Interest. In either such case, in respect of the servicing of any such Excluded Loan, a Control Termination
Event and Consultation Termination Event will be deemed to have occurred with respect to such Excluded Loan.

 

Section 3.24     Intercreditor Agreements. (a)  Each of the Master Servicer and the Special Servicer acknowledges and agrees that
each Serviced Whole Loan being serviced under this Agreement and each Mortgage Loan with mezzanine debt is subject to the terms
and provisions of the related Intercreditor Agreement and each agrees to service each such Serviced Whole Loan and each Mortgage
Loan with mezzanine debt in accordance with the related Intercreditor Agreement and this Agreement, including, without limitation,
effecting distributions and allocating reimbursement of expenses in accordance with the related Intercreditor Agreement and, in
the event of any conflict between the provisions of this Agreement and the related Intercreditor Agreement, the related Intercreditor
Agreement shall govern. Notwithstanding anything contrary in this Agreement, each of the Master Servicer and Special Servicer
agrees not to take any action with respect to a Serviced Whole Loan or a Mortgage Loan with mezzanine debt or the related Mortgaged
Property without the prior consent of the related Companion Holder or mezzanine lender, as applicable, to the extent that the
related Intercreditor Agreement provides that such Companion Holder or mezzanine lender, as applicable, is required or permitted
to consent to such action. Each of the Master Servicer and Special Servicer acknowledges and agrees that each Companion Holder
and each mezzanine lender or its respective designee has the right to purchase the related Mortgage Loan pursuant to the terms
and conditions of this Agreement and the related Intercreditor Agreement to the extent provided for therein. All parties hereto
further acknowledge and agree that any AB Whole Loan Controlling Holder will have the right to replace the Special Servicer solely
with respect to the related Serviced AB Whole Loan and shall be entitled to exercise all approval rights of the Directing Holder
regarding any Asset Status Report in respect of the related Mortgage Loan or related REO Property, without regard to the occurrence
of any Control Termination Event or

 

    -294-

     

    

 

Consultation Termination Event with respect to the related Serviced AB Whole Loan, to the
extent provided for herein and in the related Intercreditor Agreement.

 

(b)          
Neither the Master Servicer nor the Special Servicer shall have any liability for any cost, claim or damage that arises from any
entitlement in favor of a Companion Holder or a mezzanine lender under the related Intercreditor Agreement or conflict between
the terms of this Agreement and the terms of such Intercreditor Agreement. Notwithstanding any provision of any Intercreditor
Agreement that may otherwise require the Master Servicer or the Special Servicer to abide by any instruction or direction of a
Companion Holder or a mezzanine lender, neither the Master Servicer nor the Special Servicer shall be required to comply with
any instruction or direction the compliance with which requires an Advance that constitutes or would constitute a Nonrecoverable
Advance. In no event shall any expense arising from compliance with an Intercreditor Agreement constitute an expense to be borne
by the Master Servicer or the Special Servicer for its own account without reimbursement. In no event shall the Master Servicer
or the Special Servicer be required to consult with or obtain the consent of any Companion Holder or a mezzanine lender unless
such Companion Holder or mezzanine lender has delivered notice of its identity and contact information to each of the parties
to this Agreement (upon which notice each of the parties to this Agreement shall be conclusively entitled to rely). As of the
Closing Date, the contact information for the Companion Holders and mezzanine lenders is as set forth in the related Intercreditor
Agreement. In no event shall the Master Servicer or the Special Servicer, as applicable, be required to consult with or obtain
the consent of a new Directing Certificateholder or a new Controlling Class Certificateholder or consult with a new Risk Retention
Consultation Party unless the Certificate Administrator has delivered notice to the Master Servicer or the Special Servicer, as
applicable, as required under Section 3.23(e) or the Master Servicer or the Special Servicer, as applicable, have
actual knowledge of the identity and contact information of a new Directing Certificateholder, a new Controlling Class Certificateholder
or a new Risk Retention Consultation Party.

 

(c)          
No direction or disapproval of the Companion Holders or any mezzanine lender shall (a) require or cause the Master Servicer
or the Special Servicer to violate the terms of a Mortgage Loan or Serviced Companion Loan, applicable law or any provision of
this Agreement, including the Master Servicer’s or the Special Servicer’s obligation to act in accordance with the
Servicing Standard and to maintain the REMIC status of each Trust REMIC and the grantor trust status of the Grantor Trust, (b) result
in the imposition of a “prohibited transaction” or “prohibited contribution” tax under the REMIC Provisions
or (c) materially expand the scope of the Special Servicer’s, Trustee’s, the Certificate Administrator’s
or the Master Servicer’s responsibilities under this Agreement.

 

(d)         
With respect to any Serviced Pari Passu Companion Loan, notwithstanding any rights the Operating Advisor, the Directing Certificateholder
or the Risk Retention Consultation Party hereunder may have to consult with respect to any action or other matter with respect
to the servicing of such Companion Loan, to the extent the related Intercreditor Agreement provides that such right is exercisable
by the related Companion Holder or is exercisable in conjunction with any related Companion Holder, the Directing Certificateholder
and the Risk Retention Consultation Party shall not be permitted to exercise such right or, to the extent provided in the related
Intercreditor Agreement, shall be required to exercise such right in conjunction with the related Companion Holder, as applicable
(except to

 

    -295-

     

    

 

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

 

(e)          
Notwithstanding anything in this Agreement to the contrary, (a)(i) with respect to any non-Specially Serviced Loan the Special
Servicer (with respect to any Major Decision or Special Servicer Decision, unless the Master Servicer and the Special Servicer
mutually agree that, in connection with any modification, waiver or amendment that constitutes a Major Decision or a Special Servicer
Decision, the Master Servicer shall process and determine whether to consent, subject to the consent of the Special Servicer,
to such modification, waiver or amendment) or the Master Servicer (with respect to any modification, waiver or amendment that
does not constitute a Major Decision or a Special Servicer Decision), or (ii) with respect to any Specially Serviced Loan, the
Special Servicer, as applicable, shall be required (1) to provide copies of any notice, information and report that it is required
to provide to the Controlling Class Certificateholder pursuant to this Agreement with respect to any Major Decisions or Special
Servicer Decisions or the implementation of any recommended actions outlined in an Asset Status Report relating to a Serviced
Whole Loan, to the related Companion Holder, within the same time frame it is required to provide to the Controlling Class Certificateholder
(for this purpose, without regard to whether such items are actually required to be provided to the Controlling Class Certificateholder
under this Agreement due to the occurrence and continuance of a Control Termination Event or a Consultation Termination Event)
and (2) to consult with any related Companion Holder on a strictly non-binding basis, to the extent having received such notices,
information and reports, such related Companion Holder requests consultation with respect to any such Major Decisions or Special
Servicer Decisions or the implementation of any recommended actions outlined in an Asset Status Report relating to a Serviced
Whole Loan, and consider alternative actions recommended by such related Companion Holder; provided that after the expiration
of a period of ten (10) Business Days from the delivery to such related Companion Holder by the Special Servicer of written notice
of a proposed action, together with copies of the notice, information and report required to be provided to the Controlling Class
Certificateholder, the Master Servicer or the Special Servicer, as applicable, shall no longer be obligated to consult with such
related Companion Holder, whether or not such related Companion Holder has responded within such ten (10) Business Day period
(unless, the Master Servicer or the Special Servicer, as applicable, proposes a new course of action that is materially different
from the action previously proposed, in which case such ten (10) Business Day period shall be deemed to begin anew from the date
of such proposal and delivery of all information relating thereto). Notwithstanding the consultation rights of the related Companion
Holder set forth in the immediately preceding sentence, the Master Servicer or Special Servicer, as applicable, may make any Major
Decision or take any action set forth in the Asset Status Report before the expiration of the aforementioned ten (10) Business
Day period if the Master Servicer or Special Servicer, as applicable, determines that immediate action with respect thereto is
necessary to protect the interests of the Certificateholders and the related Companion Holder. In

 

    -296-

     

    

 

no event shall the Master Servicer
or the Special Servicer, as applicable, be obligated at any time to follow or take any alternative actions recommended by the
related Companion Holder.

 

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

 

(g)         
With respect to any Serviced Whole Loan, the Special Servicer shall not modify, waive or amend the terms of the related Intercreditor
Agreement such that the monthly remittance to the holder of the related Companion Loan is required earlier than 2 Business Days
after receipt by the Master Servicer of the related Periodic Payment without the consent of the Master Servicer.

 

(h)         
Any modification or amendment to an Intercreditor Agreement that would materially adversely affect the Master Servicer shall require
the prior consent of the Master Servicer.

 

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

 

Section 3.25     Rating Agency Confirmation. (a)  Notwithstanding the terms of any related Mortgage Loan documents or other provisions
of this Agreement, if any action under any Mortgage Loan documents or this Agreement requires Rating Agency Confirmation as a
condition precedent to such action, if the party (the “RAC Requesting Party”) required to obtain such Rating
Agency Confirmation from each Rating Agency has made a request to any Rating Agency for such Rating Agency Confirmation and, within
ten (10) Business Days of the Rating Agency Confirmation request being posted to the 17g-5 Information Provider’s Website,
such Rating Agency has not replied to such request or has responded in a manner that indicates that such Rating Agency is neither
reviewing such request nor waiving the requirement for Rating Agency Confirmation, then such RAC Requesting Party shall be required
to confirm (through direct communication and not by posting any confirmation on the 17g-5 Information Provider’s Website)
that the applicable Rating Agency has received the Rating Agency Confirmation

 

    -297-

     

    

 

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

 

If
there is no response to such Rating Agency Confirmation request within five (5) Business Days of such second request in a RAC
No-Response Scenario or if such Rating Agency has responded in a manner that indicates such Rating Agency is neither reviewing
such request nor waiving the requirement for Rating Agency Confirmation, then (x) with respect to any condition in any Mortgage
Loan document requiring such Rating Agency Confirmation or with respect to any other matter under this Agreement relating to the
servicing of the Mortgage Loans (other than as set forth in clause (y) below), the requirement to obtain a Rating
Agency Confirmation shall be deemed not to apply for such matter at such time (as if such requirement did not exist) with respect
to such Rating Agency and the Master Servicer (with respect to non-Specially Serviced Loans, if the Master Servicer is processing
the action requiring Rating Agency Confirmation) or the Special Servicer (with respect to Specially Serviced Loans, REO Mortgage
Loans and non-Specially Serviced Loans if the Special Servicer is processing the action requiring Rating Agency Confirmation with
respect to such non-Specially Serviced Loans), as the case may be, may then take such action if the Master Servicer (with respect
to non-Specially Serviced Loans, if the Master Servicer is processing the action requiring Rating Agency Confirmation) or the
Special Servicer (with respect to Specially Serviced Loans, REO Mortgage Loans and non-Specially Serviced Loans if the Special
Servicer is processing the action requiring Rating Agency Confirmation with respect to such non-Specially Serviced Loans), as
applicable, confirms its original determination (made prior to making such request) that taking the action with respect to which
it requested the Rating Agency Confirmation would still be consistent with the Servicing Standard, and (y) with respect to
a replacement of the Master Servicer or the Special Servicer, such condition shall be deemed not to apply (as if such requirement
did not exist) if (i) the applicable replacement master servicer or special servicer, as applicable, it has been appointed
and currently serves as a master servicer or special servicer is listed on S&P’s Select Servicer List as a U.S. Commercial
Mortgage Master Servicer or U.S. Commercial Mortgage Special Servicer, as applicable, if S&P is the non-responding Rating
Agency, (ii) the applicable replacement master servicer or special servicer is rated at least “CMS3” (in the
case of the replacement master servicer) or “CSS3” (in the case of the replacement special servicer), if Fitch is
the non-responding Rating Agency or (iii) KBRA has not cited servicing concerns with respect to the replacement master servicer
or special servicer as the sole or a material factor in any qualification, downgrade or withdrawal of the ratings (or placement
on “watch status” in contemplation of a ratings downgrade or withdrawal) of securities in any other commercial mortgage-backed
securitization transaction serviced by such replacement master servicer or special servicer prior to the time of determination,
if KBRA is the non-responding Rating Agency.

 

Any
Rating Agency Confirmation request made by the Master Servicer, Special Servicer, Certificate Administrator or Trustee, as applicable,
pursuant to this Agreement, shall be made in writing, which writing shall contain a cover page indicating the nature of the Rating
Agency Confirmation request, and shall contain all back-up material necessary for the Rating

 

    -298-

     

    

 

 Agency to process such request. Such
written Rating Agency Confirmation request shall be provided in electronic format to the 17g-5 Information Provider, and the 17g-5
Information Provider shall post such request on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).

 

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

 

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

 

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

 

Section 3.26     The Operating Advisor. (a)  The Operating Advisor shall promptly review (i) the actions of the Special Servicer
with respect to a Mortgage Loan when it is a Specially Serviced Loan (as provided in Section 3.19(d), Section 3.26 and Section 6.08) and after the occurrence and during the continuance of an Operating Advisor Consultation Event
the actions of the Special Servicer with respect to Major Decisions relating to the Mortgage Loans when they are not a Specially
Serviced Loan when a Major Decision Reporting Package has been delivered, (ii) all reports by the Special Servicer made available
to Privileged Persons on the Certificate Administrator’s Website and (iii) each Asset Status Report (after the occurrence
and during the continuance of an Operating Advisor Consultation Event) and each Final Asset Status Report delivered to the Operating
Advisor by the Special Servicer. The Operating Advisor shall perform its duties hereunder in accordance with the Operating Advisor
Standard. In addition and for the avoidance of doubt, although the Operating Advisor may have certain consultation duties with
the Master Servicer with respect to certain Major Decisions processed by the Master Servicer, the Operating Advisor will have
no obligations or responsibility at any time to review or assess the actions of the Master Servicer for compliance with the Servicing
Standard, and the Operating Advisor will not be required to consider such Master Servicer actions in connection with any Operating
Advisor Annual Report.

 

(b)          
The Operating Advisor and its Affiliates will be obligated to keep confidential any information appropriately labeled as “Privileged
Information” received from the Special Servicer or Directing Holder in connection with the Directing Holder’s exercise
of its rights under this Agreement (including, without limitation, in connection with the review and/or

 

    -299-

     

    

 

approval of any Asset
Status Report) or otherwise in connection with this transaction, except under the circumstances described in Section 3.26(f) and subject to any Privileged Information Exception or law, rule, regulation, order, judgment or decree requiring the disclosure
of such labeled Privileged Information. Subject to the terms and conditions in this Agreement related to Privileged Information,
the Operating Advisor agrees that it shall use information received from the Special Servicer pursuant to the terms of this Agreement
solely for purposes of complying with its duties and obligations hereunder.

 

(c)           
(i)  Based on the Operating Advisor’s review of any assessment of compliance report, any attestation report, any
Major Decision Reporting Package, and/or Asset Status Report (in the case of a Major Decision Reporting Package or Asset Status
Report, after the occurrence and during the continuance of an Operating Advisor Consultation Event), any Final Asset Status Report
and other reports by the Special Servicer made available to Privileged Persons that are posted on the Certificate Administrator’s
Website during the prior calendar year, the Operating Advisor shall (if, at any time during the prior calendar year, (i) any
Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan was a Specially Serviced Loan or (ii) an Operating
Advisor Consultation Event occurred during the prior calendar year) deliver to the Depositor, the Certificate Administrator (who
shall promptly post such report on the Certificate Administrator’s Website in accordance with Section 3.13(b))
and the 17g-5 Information Provider (who shall post it to the 17g-5 Information Provider’s Website in accordance with Section 3.13(c))
within one hundred twenty (120) days of the end of the prior calendar year, an annual report (the “Operating Advisor
Annual Report”), substantially in the form of Exhibit V (which form may be modified or altered as to either its
organization or content by the Operating Advisor, subject to compliance of such form with the terms and provisions of this Agreement
including, without limitation, provisions herein relating to Privileged Information; provided, however, that in
no event shall the information or any other content included in the Operating Advisor Annual Report contravene any provision of
this Agreement), that (a) sets forth whether the Operating Advisor believes, in its sole discretion exercised in good faith, that
the Special Servicer is operating in compliance with the Servicing Standard with respect to its performance of its duties under
this Agreement with respect to Specially Serviced Loans (and, after the occurrence and during the continuance of an Operating
Advisor Consultation Event, with respect to Major Decisions on Non-Specially Serviced Loans) during the prior calendar year on
a “trust-level basis”, and (b) identifies (1) which, if any, standards the Operating Advisor believes, in
its sole discretion exercised in good faith, the Special Servicer has failed to comply and (2) any material deviations from
the Special Servicer’s obligations under this Agreement with respect to the resolution or liquidation of any Specially Serviced
Loan or REO Property (other than with respect to any REO Property related to any Non-Serviced Mortgage Loan); provided,
however, that in the event the Special Servicer is replaced, the Operating Advisor Annual Report shall only relate to the
Special Servicer that was acting as Special Servicer as of December 31 in the prior calendar year and is continuing in such capacity
through the date of such Operating Advisor Annual Report; provided, further, that the Operating Advisor shall prepare
a separate Operating Advisor Annual Report relating to each Excluded Special Servicer and any Excluded Special Servicer Loan(s)
serviced by such Excluded Special Servicer. In preparing any Operating Advisor Annual Report, the Operating Advisor shall not
be required to report on instances of non-compliance with, or deviations from, the Servicing Standard or the Special Servicer’s
obligations under this Agreement that the Operating Advisor determines, in its sole discretion exercised in good faith, to be
immaterial. Only as used in

 

    -300-

     

    

 

connection with the Operating Advisor Annual Report, the term “trust-level basis” refers
to the Special Servicer’s performance of its duties with respect to the pool of Specially Serviced Loans (and, after the
occurrence and continuance of an Operating Advisor Consultation Event, with respect to Major Decisions on non-Specially Serviced
Loans) under this Agreement taking into account the Special Servicer’s specific duties under this Agreement as well as the
extent to which those duties were performed in accordance with the Servicing Standard, with reasonable consideration by the Operating
Advisor of any Assessment of Compliance Report, Attestation Report, Major Decision Reporting Package, Asset Status Report (after
the occurrence and during the continuance of an Operating Advisor Consultation Event), Final Asset Status Report and other information,
in each case, delivered to the Operating Advisor by the Special Servicer (other than any communications between the Directing
Holder and the Special Servicer that would be Privileged Information) pursuant to this Agreement. Subject to the restrictions
in this Agreement, including, without limitation, Section 3.26(f) hereof, each such Operating Advisor Annual Report
shall comply with all of the confidentiality requirements described in this Agreement regarding Privileged Information (subject
to any permitted exceptions). Such Operating Advisor Annual Report shall be delivered to the Depositor, the Certificate Administrator
(which shall promptly post such Operating Advisor Annual Report on the Certificate Administrator’s Website in accordance
with Section 3.13(b)) and the 17g-5 Information Provider (which shall promptly post such Operating Advisor Annual
Report on the 17g-5 Information Provider’s Website in accordance with Section 3.13(c)); provided, however,
that the Special Servicer shall be given an opportunity to review the Operating Advisor Annual Report at least ten (10) days prior
to its delivery to the Depositor, the Certificate Administrator and the 17g-5 Information Provider. The Operating Advisor shall
have no obligation to adopt any comments to the Operating Advisor Annual Report that are provided by the Special Servicer.

 

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

 

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

 

(iv)          In the event a lack of access to Privileged Information limits or prohibits the Operating Advisor from performing its duties under
this Agreement, the Operating Advisor shall set forth any such limitations or prohibitions in the related Operating

 

    -301-

     

    

 

Advisor Annual
Report, and the Operating Advisor shall not be subject to any liability arising from such limitations or prohibitions.

 

(d)          
(i)  After the calculation has been finalized (and if an Operating Advisor Consultation Event has occurred and is continuing
prior to the utilization) by the Special Servicer of any of the calculations related to (A) Appraisal Reduction Amounts,
(B) Collateral Deficiency Amounts or (C) net present value in accordance with Section 1.02(iv), the Special Servicer
shall forward such calculations, together with any supporting material or additional information necessary in support thereof
(including such additional information reasonably requested by the Operating Advisor to confirm the mathematical accuracy of such
calculations, but not including any Privileged Communications and, in the case of any Appraisal Reduction Amount or Collateral
Deficiency Amount, only to the extent the Master Servicer has provided such information to the Special Servicer), to the Operating
Advisor promptly, but in any event no later than two (2) Business Days after preparing such calculations, and the Operating Advisor
shall no later than three (3) Business Days after receipt of such calculations and any supporting or additional materials recalculate
the accuracy of the mathematical calculations and the corresponding application of the non-discretionary portion of the applicable
formulas required to be utilized in connection with any such calculation.

 

(ii)         In connection with this Section 3.26(d), in the event the Operating Advisor does not agree with the mathematical calculations
of the net present value, Appraisal Reduction Amount or Collateral Deficiency Amount (as calculated by the Special Servicer) or
the application of the applicable non-discretionary portions of the formula required to be utilized for such calculation, the
Operating Advisor and the Special Servicer shall consult with each other in order to resolve any material inaccuracy in the mathematical
calculations or the application of the non-discretionary portions of the related formula in arriving at those mathematical calculations
or any disagreement within five (5) Business Days of delivery of such calculations to the Operating Advisor. The Master Servicer
shall cooperate with the Special Servicer and provide any information reasonably requested by the Special Servicer necessary for
the calculation of the Appraisal Reduction Amount that is in the Master Servicer’s possession or reasonably obtainable by
the Master Servicer. In the event the Operating Advisor and the Special Servicer are not able to resolve such inaccuracies or
disagreement prior to the end of such five (5) Business Day period, the Operating Advisor shall promptly notify the Certificate
Administrator of such disagreement and the Certificate Administrator shall examine the calculations and supporting materials provided
by the Operating Advisor and the Special Servicer and determine which calculation is to apply (and shall provide prompt written
notice of such determination to the Operating Advisor and the Special Servicer). In making such determination, the Certificate
Administrator may hire an independent third party to assist with any such calculation at the expense of the Trust. The Certificate
Administrator shall be entitled to conclusively rely on such third party calculation.

 

(e)           Notwithstanding the foregoing, prior to the occurrence and continuance of an Operating Advisor Consultation Event, the Operating
Advisor’s review will be limited to an after-the-action review of the reports and material described above (together with
any additional information and material reviewed by the Operating Advisor) and, therefore, it shall have no involvement with respect
to collateral substitutions, assignments, workouts, modifications,

 

    -302-

     

    

 

consents, waivers, insurance policies, mortgagor substitutions,
lease changes, additional borrower debt, defeasances, property management changes, releases from escrow, assumptions or other
similar actions that the Special Servicer may perform under this Agreement and will have no obligations at any time with respect
to any Non-Serviced Mortgage Loan. In addition, with respect to the Operating Advisor’s review of net present value calculations
as described above, the Operating Advisor’s recalculation will not take into account the reasonableness of Special Servicer’s
property and borrower performance assumptions or other similar discretionary portions of the net present value calculation.

 

(f)           
The Operating Advisor and its Affiliates shall keep all information appropriately labeled as “Privileged Information”
confidential and shall not, without the prior written consent of the Special Servicer and (for so long as no Consultation Termination
Event is continuing) the Directing Holder (with respect to any Mortgage Loan other than a Non-Serviced Whole Loan and any applicable
Excluded Loan), disclose such information to any other Person (including any Certificateholders which are not then included in
the Control Eligible Regular Interests, other than the Directing Certificateholder and the Risk Retention Consultation Party),
other than (i) to the extent expressly set forth herein, to the other parties to this Agreement with a notice indicating
that such information is Privileged Information, (ii) pursuant to a Privileged Information Exception or (iii) where
necessary to support specific findings or conclusions concerning allegations of deviations from the Servicing Standard (A) in
the Operating Advisor Annual Report or (B) in connection with a recommendation by the Operating Advisor to replace the Special
Servicer. Each party to this Agreement that receives “Privileged Information” from the Operating Advisor with a notice
stating that such information is Privileged Information shall not disclose such Privileged Information to any other Person without
the prior written consent of the Special Servicer and, unless a Control Termination Event has occurred, the Directing Certificateholder
(with respect to any Mortgage Loan other than a Non-Serviced Whole Loan and other than an Excluded Loan) other than pursuant to
a Privileged Information Exception. In addition and for the avoidance of doubt, while the Operating Advisor may serve in a similar
capacity with respect to Other Securitizations that involve the same parties or borrower involved in this securitization, the
knowledge of the employees performing operating advisor functions for such Other Securitizations are not imputed to different
employees of the Operating Advisor performing the obligations hereunder. Notwithstanding the foregoing, the Operating Advisor
shall be permitted to share Privileged Information with its Affiliates and any subcontractors of the Operating Advisor that agree
in writing to be bound by the same confidentiality provisions applicable to the Operating Advisor.

 

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

 

(h)         
As compensation for its activities hereunder, the Operating Advisor shall be entitled to receive the Operating Advisor Fee on
each Distribution Date with respect to each Mortgage Loan (including the Serviced Mortgage Loans but not any Non-Serviced Mortgage
Loans nor any Companion Loan) or each REO Mortgage Loan. As to each Mortgage Loan and each REO Loan, the Operating Advisor Fee
shall accrue from time to time at the Operating Advisor Fee Rate and shall be computed on the basis of the Stated Principal Balance
of such

 

    -303-

     

    

 

Mortgage Loan or REO Mortgage Loan, as the case may be, and in the same manner as interest is calculated on the related
Mortgage Loan or REO Mortgage Loan, as the case may be, and, in connection with any partial month interest payment, for the same
period respecting which any related interest payment due on the related Mortgage Loan or deemed to be due on such REO Mortgage
Loan is computed. The Operating Advisor Fee shall be payable from funds on deposit in the Collection Account as provided in Section 3.05(a)(ii) of this Agreement.

 

The
Operating Advisor shall be entitled to reimbursement of any Operating Advisor Expenses provided for pursuant to Section 6.04(a) and/or 6.04(b) hereof, such amounts to be reimbursed from amounts on deposit in the Collection Account as provided
by Section 3.05(a). Each successor Operating Advisor shall be required to acknowledge and agree to the terms of the
preceding sentence.

 

In
addition, the Operating Advisor Consulting Fee shall be payable to the Operating Advisor with respect to each Major Decision for
which the Operating Advisor has consultation obligations hereunder. The Operating Advisor Consulting Fee shall be payable from
funds on deposit in the Collection Account as provided in Section 3.05(a)(ii) of this Agreement, but, with respect
to the period when the outstanding Certificate Balances of the Control Eligible Certificates have not been reduced to zero as
a result of the allocation of Realized Losses to such Certificates, only to the extent such Operating Advisor Consulting Fee is
actually received from the related Mortgagor; provided, however, that to the extent such Operating Advisor Consulting
Fee is incurred after the outstanding Certificate Balances of the Control Eligible Regular Interests have been reduced to zero
as a result of the allocation of Realized Losses to such Certificates, such Operating Advisor Consulting Fee shall be payable
in full to the Operating Advisor as a Trust Fund expense. When the Operating Advisor has consultation obligations with respect
to a Major Decision under this Agreement, the Master Servicer or the Special Servicer, as the case may be, shall use commercially
reasonable efforts to collect the applicable Operating Advisor Consulting Fee from the related Mortgagor in connection with such
Major Decision that are consistent with the efforts that the Master Servicer or the Special Servicer processing the Major Decision
would use to collect any Mortgagor-paid fees owed to it in accordance with the Servicing Standard, but only to the extent not
prohibited by the related Mortgage Loan documents. The Master Servicer or Special Servicer, as the case may be, may waive or reduce
the amount of any Operating Advisor Consulting Fee payable by the related Mortgagor if it determines that such full or partial
waiver is in accordance with the Servicing Standard, but in no event shall the Master Servicer or the Special Servicer take any
enforcement action with respect to the collection of such Operating Advisor Consulting Fee other than requests for collection;
provided that the Master Servicer or the Special Servicer, as applicable, shall consult, on a non-binding basis, with the
Operating Advisor prior to any such waiver or reduction. Notwithstanding the foregoing, the Operating Advisor will have no obligations
or consultation rights as Operating Advisor with respect to: (i) any Non-Serviced Whole Loan or any related REO Property
or (ii) with respect to any Serviced AB Whole Loan, prior to the occurrence and continuance of an AB Control Appraisal Period;
provided, further, that the Operating Advisor shall not be entitled to an Operating Advisor Consulting Fee with
respect to any Non-Serviced Whole Loan.

 

(i)          
After the occurrence and during the continuance of a Consultation Termination Event, the Operating Advisor may be removed upon
(i) the written direction of

 

    -304-

     

    

 

Certificateholders evidencing not less than 25% of the Voting Rights (taking into account the application
of Appraisal Reduction Amounts to notionally reduce the Certificate Balances of Classes to which such Appraisal Reduction Amounts
are allocable) requesting a vote to replace the Operating Advisor with a replacement Operating Advisor selected by such Certificateholders
(provided that the proposed replacement Operating Advisor is an Eligible Operating Advisor), and (ii) payment by such requesting
Holders to the Certificate Administrator of all reasonable fees and expenses to be incurred by the Certificate Administrator in
connection with administering such vote. The Certificate Administrator shall promptly provide written notice to all applicable
Certificateholders of such request by posting such notice on the Certificate Administrator’s Website in accordance with
Section 3.13(b), and concurrently by mail, and conduct the solicitation of votes of all applicable Certificates in such
regard. Upon the vote or written direction of Holders of at least 75% of the Voting Rights (taking into account the application
of Appraisal Reduction Amounts to notionally reduce the Certificate Balances of Classes to which such Appraisal Reduction Amounts
are allocable), the Trustee shall immediately replace the Operating Advisor with the replacement operating advisor.

 

(j)          After
the occurrence of an Operating Advisor Termination Event, the Trustee may, and upon the written direction of Certificateholders
representing at least 25% of the Voting Rights (taking into account the application of any Appraisal Reduction Amounts to notionally
reduce the Certificate Balance of the Classes of Certificates), the Trustee shall promptly terminate the Operating Advisor for
cause and appoint a replacement operating advisor that is an Eligible Operating Advisor; provided that no such termination
shall be effective until a successor operating advisor has been appointed and has assumed all of the obligations of the Operating
Advisor under this Agreement; provided, further, that no such termination shall terminate the rights of the Operating
Advisor that accrued prior to such termination, including accrued and unpaid compensation and indemnification rights. The Trustee
may rely on a certification by the replacement operating advisor that it is an Eligible Operating Advisor. If the Trustee is unable
to find a replacement operating advisor that is an Eligible Operating Advisor within thirty (30) days of the termination of the
Operating Advisor, the Depositor shall be permitted to find a replacement. Upon any termination of the Operating Advisor and appointment
of a successor to the Operating Advisor, the Trustee will, as soon as possible, be required to give written notice of the termination
and appointment to the Special Servicer, the Master Servicer, the Certificate Administrator, the 17g-5 Information Provider (for
posting to the 17g-5 Information Provider’s Website), the Depositor, the Directing Certificateholder (only for so long as
no Consultation Termination Event has occurred and is continuing), the Risk Retention Consultation Party, any Companion Holder
and the Certificateholders.

 

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

 

    -305-

     

    

 

(l)          Prior
to the occurrence and continuance of a Control Termination Event, the Directing Certificateholder shall have the right to consent,
such consent not to be unreasonably withheld, conditioned or delayed, to the identity of any replacement Operating Advisor appointed
pursuant to this Section 3.26; provided, further, that such consent will be deemed to have been granted if
no objection is made within ten (10) Business Days following the Directing Certificateholder’s receipt of the request for
consent and, if granted or deemed granted, such consent cannot thereafter be revoked or withdrawn.

 

(m)       
The Operating Advisor may resign from its obligations and duties hereby imposed on it (a) upon thirty (30) days prior written
notice to the Depositor, the Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Asset
Representations Reviewer, the Directing Certificateholder and the Risk Retention Consultation Party, if applicable, if the
Operating Advisor has secured a replacement operating advisor that is an Eligible Operating Advisor and (b) upon the
appointment of, and the acceptance of such appointment by, a successor Operating Advisor that is an Eligible Operating
Advisor. No such resignation by the Operating Advisor shall become effective until the replacement Operating Advisor shall
have assumed the resigning Operating Advisor’s responsibilities and obligations. The resigning Operating Advisor shall
pay all costs and expenses (including costs and expenses incurred by the Trustee and the Certificate Administrator)
associated with a transfer of its duties pursuant to this Section 3.26.

 

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

 

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

 

(p)        With
respect to the determination of whether an Operating Advisor Consultation Event has occurred and is continuing, or has terminated,
the Operating Advisor shall be entitled to rely solely on its receipt from the Certificate Administrator of notice thereof pursuant
to Section 3.23(m) of this Agreement, and, with respect to any obligations of the Operating Advisor that are performed
only after the occurrence and continuance of an Operating Advisor Consultation Event, the Operating Advisor shall have no obligation
to perform any such duties until the receipt of such notice.

 

(q)       
The Operating Advisor will be permitted to delegate its duties to agents or subcontractors so long as the related agreements
or arrangements with such agents or

 

    -306-

     

    

 

subcontractors are consistent with the provisions of this Agreement; provided that
no agent or subcontractor may (i) be affiliated with a Mortgagor, Sponsor, Master Servicer, the Special Servicer, the
Depositor, the Certificate Administrator, the Trustee, the Directing Certificateholder or any of their respective Affiliates
or (ii) have been paid any fees, compensation or other remuneration by an Underwriter, Master Servicer, the Special Servicer,
the Depositor, the Certificate Administrator, the Trustee, the Directing Certificateholder or any of their respective
Affiliates in connection with due diligence or other services with respect to any Mortgage Loan prior to the Closing Date.
Notwithstanding the foregoing sentence, the Operating Advisor shall remain obligated and primarily liable for its obligations
hereunder in accordance with the provisions of this Agreement without diminution of such obligation or liability or related
obligation or liability by virtue of such delegation or arrangements or by virtue of indemnification from any Person acting
as its agents or subcontractor to the same extent and under the same terms and conditions as if the Operating Advisor alone
were performing its obligations under this Agreement. The Operating Advisor shall be entitled to enter into an agreement with
any agent or subcontractor providing for indemnification of the Operating Advisor by such agent or subcontractor, and nothing
contained in this Agreement shall be deemed to limit or modify such indemnification.

 

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

 

(b)        No
provision of this Agreement shall be construed to relieve the Companion Paying Agent from liability for its negligent failure
to act, bad faith or its own willful misfeasance; provided, however, that the duties and obligations of the Companion
Paying Agent shall be determined solely by the express provisions of this Agreement. The Companion Paying Agent shall not be liable
except for the performance of such duties and obligations, no implied covenants or obligations shall be read into this Agreement
against the Companion Paying Agent. In the absence of bad faith on the part of the Companion Paying Agent, the Companion Paying
Agent may conclusively rely, as to the truth and correctness of the statements or conclusions expressed therein, upon any resolutions,
certificates, statements, opinions, reports, documents, orders or other instrument furnished to the Companion Paying Agent by
any Person and which on their face do not contradict the requirements of this Agreement.

 

(c)         In
the case of each of the Serviced Companion Loans, upon the resignation or removal of the Master Servicer pursuant to ARTICLE
VII of this Agreement, the Master Servicer, as the Companion Paying Agent, shall be deemed simultaneously to resign or be
removed.

 

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

 

Section
3.28     Companion Register. The Companion Paying Agent shall maintain a register (the “Companion
Register”) with respect to each Serviced Companion Loan on which it will record the names and address of, and wire transfer
instructions for, the

 

    -307-

     

    

 

Companion Holders from time to time, to the extent such information is provided in writing to it by each
Companion Holder. The initial Companion Holders, along with their respective name and address, are listed on Exhibit S
hereto. In the event a Companion Holder transfers a Companion Loan without notice to the Companion Paying Agent, the Companion
Paying Agent shall have no liability for any misdirected payment in such Companion Loan and shall have no obligation to recover
and redirect such payment.

 

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

of the same.

 

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

any Excluded Controlling Class Loans on the Certificate Administrator’s Website (unless a loan-by-loan segregation is later
performed by the Certificate Administrator in which case such access shall only be prohibited with respect to the related Excluded
Controlling Class Loans). None of the Master Servicer, the Special Servicer or the Operating Advisor shall have any obligations
to separately label and deliver any Excluded Information in accordance with this Section 3.30 until such party has received

Nothing set forth in this Agreement shall prohibit the Directing Holder or any Controlling Class Certificateholder from receiving,

Excluded Controlling Class Holder via the Certificate Administrator’s Website, such Directing Certificateholder or Controlling
Class Certificateholder that is not a Borrower Party with respect to the related Excluded Controlling Class Loan shall be permitted

Section
3.31     Horizontal Credit Risk Retention.

 

(a)        The
Third Party Purchaser, prior to its acquisition of Certificates that constitute the Required Third Party Purchaser Retention Amount,
will be required to enter into an agreement with the Retaining Sponsor (the “Credit Risk Retention Compliance Agreement”).

 

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

Section
3.32    Resignation Upon Prohibited Risk Retention Affiliation. Under the Credit Risk Retention Rule, the Third Party Purchaser
or any successor third party purchaser is prohibited from being Risk Retention Affiliated with, among other persons, the Master
Servicer, the Trustee, the Certificate Administrator, the Operating Advisor or the Asset Representations Reviewer. As long as
the prohibition exists, upon the occurrence of (i) a Servicing Officer of the Master Servicer or a Responsible Officer of the
Certificate Administrator or the Trustee, as applicable, obtaining actual knowledge that the Master Servicer, the Certificate
Administrator or the Trustee, as applicable, is or has become Risk Retention Affiliated with or a Risk Retention Affiliate of
the Third Party Purchaser or any successor third party purchaser (in such case, an “Impermissible TPP Affiliate”),
(ii) the Master Servicer, the Certificate Administrator or the Trustee receiving written notice by any other party to this Agreement,
the Third Party Purchaser or any successor third party purchaser, any Sponsor or any Underwriter or Initial Purchaser that the
Master Servicer, the Certificate Administrator or the Trustee, as applicable, is or has become an Impermissible TPP Affiliate,
or (iii) the Operating Advisor or the Asset Representations Reviewer obtaining actual knowledge that it is or has become a Risk
Retention Affiliate of the Third Party Purchaser, any successor third party purchaser or any other party to this Agreement (in
such case, an “Impermissible Operating Advisor Affiliate” and “Impermissible Asset Representations
Reviewer Affiliate”, respectively; and either of an Impermissible TPP Affiliate, an Impermissible Operating Advisor
Affiliate and an Impermissible Asset Representations Reviewer Affiliate being an “Impermissible Risk Retention Affiliate”),
such Impermissible Risk Retention Affiliate shall be required to promptly notify the Retaining Sponsor and the other parties to
this Agreement and resign in accordance with Section 3.26, Section 6.05, Section 8.07 or Section 12.03,
as applicable. The resigning Impermissible Risk Retention Affiliate will be required to bear all reasonable out-of-pocket costs
and expenses of each other party to this Agreement, the Issuing Entity and each Rating Agency in connection with such resignation
as and to the extent required under this Agreement; provided, however, if the affiliation causing an Impermissible
Risk Retention Affiliate is the result of the Third Party Purchaser or any successor third party purchaser acquiring an interest
in

 

    -310-

     

    

 

such Impermissible Risk Retention Affiliate or an affiliate of such Impermissible Risk Retention Affiliate, then such costs
and expenses will be an expense of the Issuing Entity.

 

Section
3.33     Litigation Control.

 

(a)       
With respect to any Serviced Mortgage Loan, any Serviced Pari Passu Companion Loan or any related REO Loan or related REO Property,
the Special Servicer shall, in accordance with the Servicing Standard, direct, manage, prosecute and/or defend any action brought
by a Mortgagor, guarantor, or other obligor on the related Note or any Affiliates thereof (each a “Borrower Related Party”)
against the Trust, the Master Servicer and/or the Special Servicer or any predecessor master servicer or special servicer, and
represent the interests of the Trust in any litigation relating to the rights and obligations of the Trust, or of the Mortgagor
or other Borrower Related Party under the related Mortgage Loan documents, or with respect to the related Mortgaged Property or
other collateral securing such Mortgage Loan (or Serviced Whole Loan), or otherwise with respect to the enforcement of the obligations
of a Borrower Related Party under the related Mortgage Loan documents (“Trust Related Litigation”). In the event that
the Master Servicer is named in any Trust Related Litigation but the Special Servicer is not named in such Trust Related Litigation
(regardless of whether the Trust is named in such Trust Related Litigation), the Master Servicer shall notify the Special Servicer
of such litigation as soon as practicable but in any event no later than within ten (10) Business Days of the Master Servicer
receiving service of such Trust Related Litigation.

 

(b)       
To the extent the Master Servicer is named in the Trust Related Litigation, and neither the Trust nor the Special Servicer is
named, in order to effectuate the role of the Special Servicer as contemplated by the immediately preceding subsection, the Master
Servicer shall use reasonable efforts to (i) provide monthly status reports to the Special Servicer regarding such Trust Related
Litigation; (ii) seek to have the Trust replace the Master Servicer as the appropriate party to the lawsuit; and (iii) so long
as the Master Servicer remains a party to the lawsuit, consult with and act at the direction of the Special Servicer with respect
to material decisions and material monetary settlements related to the interests of the Trust in such Trust Related Litigation,
including but not limited to the selection of counsel; provided that the Master Servicer shall have the right to engage
separate counsel relating to claims or counter-claims against or on behalf of the Master Servicer to the extent set forth in Section
3.33(e) and provided, further, that if there are claims or counter-claims against or on behalf of the Master Servicer
and the Master Servicer has not determined that separate counsel is required for such claims or counter-claims, such counsel shall
be reasonably acceptable to the Master Servicer.

 

(c)        The
Special Servicer shall not (i) undertake (or direct the Master Servicer to undertake) any material settlement of any Trust Related
Litigation or (ii) initiate any material Trust Related Litigation unless and until (A) it has notified in writing the Directing
Certificateholder (only if the related Mortgage Loan is not an Excluded Loan and prior to the occurrence and continuance of a
Consultation Termination Event) (to the extent the identity of the Directing Certificateholder is actually known to the Special
Servicer; provided that the Special Servicer shall make due inquiry of the Certificate Administrator as to the identity
of the Directing Certificateholder) and the related holder of any Serviced Companion Loan (if such matter affects such related
Serviced Companion Loan) (to the extent the identity of the holder of such Serviced Companion Loan is actually known to the Special
Servicer), and (B) the Directing

 

    -311-

     

    

 

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

 

(d)        Notwithstanding
Section 3.33(e), above, neither the Special Servicer nor the Master Servicer shall follow any advice, direction or consultation
provided by the Directing Certificateholder (or any other party to this Agreement) that would require or cause the Special Servicer
or the Master Servicer, as applicable, to violate any applicable law, be inconsistent with the Servicing Standard, require or
cause the Special Servicer or the Master Servicer, as applicable, to violate provisions of this Agreement, require or cause the
Special Servicer or the Master Servicer, as applicable, to violate the terms of any Mortgage Loan or Serviced Whole Loan, expose
any Certificateholder or any party to this Agreement or their Affiliates, officers, directors or agents to any claim, suit or
liability, cause an Adverse REMIC Event, or materially expand the scope of the Special Servicer’s, the Master Servicer’s,
the Certificate Administrator’s or the Trustee’s, as applicable, responsibilities under this Agreement.

 

(e)        Notwithstanding
the right of the Special Servicer to represent the interests of the Trust in Trust Related Litigation, the Master Servicer shall
retain the right to make determinations in the Master Servicer’s sole discretion relating to claims or counter-claims against
or on behalf of the Master Servicer, including but not limited to the right to engage separate counsel, to make settlement decisions
and to appear in any proceeding on its own behalf, the cost of which shall be subject to indemnification as and to the extent
provided in this Agreement.

 

(f)       
 Further, nothing in this Section 3.33 shall require the Master Servicer, the Special Servicer or any other party
to this Agreement to take or fail to take any action which, in such party’s reasonable judgment, may result in a
violation of the REMIC Provisions of the Code, subject the Master Servicer, the Special Servicer or other such party to
liability, or materially expand the scope of the Master Servicer’s, the Special Servicer or such party’s
obligations under this Agreement.

 

(g)       
In the event where the Master Servicer or Special Servicer is a named party neither the Special Servicer nor the Master Servicer
will settle on behalf of the other such party, any Loan-Related Litigation without such other party’s consent unless: (i)
such settlement does not contain or require any admission of liability, wrongdoing or consent to injunctive relief on the part
of such other party and such other party is fully released, (ii) the cost of such settlement or any resulting judgment is and
shall be paid by the Trust and payment of such cost or judgment is provided for in this Agreement, (iii) such other party is and
shall be indemnified

 

    -312-

     

    

 

as and to the extent provided in this Agreement for all costs and expenses incurred in defending and settling
the Loan-Related Litigation and for any judgment, (iv) any such action taken by the Master Servicer at the direction of the Special
Servicer shall be deemed (as to the Master Servicer) to be in compliance with the Servicing Standard and (v) the Master Servicer
or the Special Servicer, as applicable, provides such other party with assurance reasonably satisfactory to such other party,
as to the items in clauses (i), (ii), (iii) and (iv).

 

(h)       
In the event both the Master Servicer and the Special Servicer or the Trust are named in Trust Related Litigation, the Master
Servicer and the Special Servicer shall cooperate with each other to afford the Master Servicer and the Special Servicer the rights
afforded to such party in this Section 3.33.

 

(i)         This
Section 3.33 shall not apply in the event the Special Servicer authorizes the Master Servicer, and the Master Servicer
agrees (both authority and agreement to be in writing), to make certain decisions or control certain Trust Related Litigation
on behalf of the Trust in accordance with the Servicing Standard.

 

(j)         Notwithstanding
the foregoing, and subject to the requirements of the second sentence in the second paragraph of Section 3.01(a) of this
Agreement, (i) in the event that any action, suit, litigation or proceeding names the Trustee, Certificate Administrator or Custodian,
in its respective individual capacity, or in the event that any judgment is rendered against the Trustee, Certificate Administrator
or Custodian, as applicable, in its individual capacity, the Trustee, Certificate Administrator or Custodian, as applicable, upon
prior written notice to the Master Servicer or the Special Servicer, as applicable, may retain counsel and appear in any such
proceeding on its own behalf in order to protect and represent its interests (but not to otherwise direct, manage or prosecute
such litigation or claim); (ii) in the event of any action, suit, litigation or proceeding, other than an action, suit, litigation
or proceeding relating to the enforcement of the obligations of a Mortgagor, guarantor or other obligor under the related Mortgage
Loan documents, or otherwise relating to one or more Mortgage Loans or Mortgaged Properties, neither the Master Servicer nor the
Special Servicer shall, without the prior written consent of the Trustee, Certificate Administrator or Custodian, as applicable,
(A) initiate an action, suit, litigation or proceeding in the name of the Trustee, Certificate Administrator or Custodian, as
applicable, whether in such capacity or individually, (B) engage counsel to represent the Trustee, Certificate Administrator or
Custodian, as applicable, (C) settle any claim giving rise to liability to the Trustee, Certificate Administrator or Custodian,
as applicable, in its individual capacity, or (D) prepare, execute or deliver any government filings, forms, permits, registrations
or other documents or take any other similar actions with the intent to cause, and that actually causes, the Trustee, Certificate
Administrator or Custodian, as applicable, to be registered to do business in any state (provided that neither the Master Servicer
nor the Special Servicer shall be responsible for any delay due to the unwillingness of the Trustee, Certificate Administrator
or Custodian to grant such consent); and (iii) in the event that any court finds that the Trustee, Certificate Administrator or
Custodian, as applicable, is a necessary party in respect of any action, suit, litigation or proceeding relating to or arising
from this Agreement or any Mortgage Loan, the Trustee, the Certificate Administrator or the Custodian, as applicable, shall have
the right to retain counsel and appear in any such proceeding on its own behalf in order to protect and represent its interests,
whether as Trustee, Certificate Administrator or Custodian, as applicable, or individually (but not to otherwise direct, manage
or prosecute such litigation or

 

    -313-

     

    

 

claim); provided, however, nothing in this subsection shall be interpreted to preclude the Special
Servicer (with respect to any material Trust Related Litigation, with the consent or consultation of the Directing Certificateholder
prior to the occurrence and continuance of a Control Termination Event or Consultation Termination Event, respectively) from initiating
any action, suit, litigation or proceeding in its name as representative of the Trust.

 

Notwithstanding
the foregoing or anything to the contrary in this Section 3.33, this Section 3.33 shall not apply to any Trust Related
Litigation and shall have no force and effect with respect thereto, in the event that either (i) at the time such Trust Related
Litigation is commenced or at any time during the continuance of such Trust Related Litigation, Rialto Capital Advisors, LLC is
no longer the Special Servicer with respect to the related Mortgage Loan or related Whole Loan or has received notice of its replacement
as Special Servicer with respect to the related Mortgage Loan or related Whole Loan whether or not such replacement is effective
or (ii) the Depositor, any Sponsor, any Mortgage Loan Seller, any Initial Purchaser, or any of their respective affiliates is
an adverse party (with respect to the Trust or the Special Servicer) to such Trust Related Litigation or holds any interest which
is adverse to the Trust or the Special Servicer in the related Mortgage Loan or related Whole Loan (or any portion thereof) or
the related Mortgaged Property to which Trust Related Litigation relates, unless otherwise agreed to in writing by each of the
Depositor, Sponsor, Mortgage Loan Seller, Initial Purchaser, or affiliate that is such a party or holds such interest, and in
each case under clauses (i) and (ii) above, the applicable party listed above shall provide notice of such occurrence
to the Master Servicer pursuant to the terms of this Agreement. For the further avoidance of doubt, in such circumstance described
in this paragraph, the rights and obligations of the Master Servicer and the Special Servicer relating to litigation shall be
as otherwise set forth in this Agreement.

(c)         On
each Distribution Date, each Lower-Tier Regular Interest shall be deemed to receive distributions in respect of principal or reimbursement

the Holders of the respective Corresponding Regular Interest as provided in Section 4.01(a), Section 4.01(d), Section
4.01(d), and Section 4.01(i) such that at all times the Lower-Tier Principal Amount of each Class of Lower-Tier Regular
Interests is equal to the Certificate Balance of the Corresponding Regular Interest. On each Distribution Date, each Lower-Tier
Regular Interest shall be deemed to receive distributions in respect of interest in an amount equal to the Interest Distribution
Amount in respect of its Corresponding Regular Interest plus a pro rata portion of the Interest Distribution Amount in
respect of (i) in the case of the Class LA-1, Class LA-2, Class LA-3, Class LA-4, Class LA-5, Class LA-SB and Class LA-S Uncertificated
Interests, the Class X-A Regular Interest, (ii) in the case of the Class LB and Class LC Uncertificated Interests, the Class X-B
Regular Interest and (iii) in the case of the Class LE Uncertificated Interest, the Class X-E Regular Interest, in each case,
computed based on an interest rate equal to the excess of the Weighted Average Net Mortgage Rate over the Pass-Through Rate of
the Corresponding Regular Interest and a notional amount equal to its related Lower-Tier Principal Amount, in each case to the
extent actually distributable thereon as provided in Section 4.01(a). Amounts distributable pursuant to this paragraph
are referred to herein collectively as the “Lower-Tier Distribution Amount”, and shall be made by the Certificate
Administrator by deeming such Lower-Tier Distribution Amount to be withdrawn from the Lower-Tier REMIC Distribution Account to
be deposited in the Upper-Tier REMIC Distribution Account.

 

As
of any date, the principal balance of each Lower-Tier Regular Interest shall equal the Certificate Balance of the Corresponding
Regular Interest with respect thereto, as adjusted for the allocation of Realized Losses, as provided in Sections 4.04(b)
and 4.04(c). The initial principal balance of each Lower-Tier Regular Interest shall equal the respective Original Lower-Tier
Principal Amount. The pass-through rate with respect to each Lower-Tier Regular Interest shall be the rate per annum set
forth in the Preliminary Statement hereto.

 

    -330-

     

    

 

Any
amount that remains in the Lower-Tier REMIC Distribution Account on each Distribution Date after distribution of the Lower-Tier
Distribution Amount, and distribution of Yield Maintenance Charges pursuant to Section 4.01(e)(iii) shall be distributed
to the Holders of the Class R Certificates in respect of the Class LR Interest (but only to the extent of the Available Funds
for such Distribution Date remaining in the Lower-Tier REMIC Distribution Account, if any).

 

(d)        While
the Certificate Balance of any Class of Regular Interest has been reduced to zero, such Class shall not be entitled to any further
distributions in respect of interest or principal other than reimbursement of Realized Losses and other amounts provided for in
this Section 4.01 and the last sentence of Section 4.04(a).

 

(e)        Funds
on deposit in the Distribution Account on each Distribution Date that represent Yield Maintenance Charges received by the Trust
with respect to any Mortgage Loan or REO Loan during the related Collection Period, in each case net of any Liquidation Fees payable
therefrom, shall be distributable as follows: if, during any particular Collection Period, any Yield Maintenance Charge is collected
and allocable with respect to any Mortgage Loan, then on the Distribution Date corresponding to that Collection Period, the Certificate
Administrator shall pay that Yield Maintenance Charge in the following manner: (a) pro rata, between (i) the group (the
“YM Group A”) of Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A and Class A-S
Regular Interests, 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 and Class D Regular Interests, based upon the aggregate amount of principal
distributed to the Classes of Regular Interests in each YM Group on such Distribution Date; and (b) as among the respective Classes
of Regular Interests 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 Regular Interests (other than Class X Regular Interests) 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
Regular Interests on such Distribution Date and whose denominator is the total amount of principal distributed to all of the Regular
Interests (other than Class X Regular Interests) in such YM Group on such Distribution Date, (y) the Base Interest Fraction for
the related principal prepayment with respect to such Class of Regular Interests, 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 Regular Interests in such YM Group, in the case of amounts distributable to
YM Group A, to the Class X-A Regular Interest and in the case of amounts distributable to YM Group B, to the Class X-B Regular
Interest.

 

For
purposes of the first paragraph of this Section 4.01(e), the relevant “Base Interest Fraction” in connection
with any Principal Prepayment of any Mortgage Loan that provides for the payment of a Yield Maintenance Charge, and with respect
to any principal prepayment on any Mortgage Loan and with respect to any Class of Class A-1, Class A-2, Class A-3, Class A-4,
Class A-5, Class A-SB, Class A-S, Class B, Class C and Class D Regular Interests is a fraction (a) whose numerator is the greater
of (x) zero and (y) the difference between (i) the Pass-Through Rate of such Class of Regular Interests and (ii) the discount
rate used in accordance with the related Mortgage Loan documents in calculating the Yield Maintenance Charge with respect to such
principal prepayment and (b) whose denominator is the

 

    -331-

     

    

 

greater of zero and the difference between (i) the Mortgage Rate on such
Mortgage Loan (or with respect to any Mortgage Loan that is part of a Serviced Whole Loan, the Mortgage Rate of such Serviced
Whole Loan) and (ii) the discount rate used in accordance with the related Mortgage Loan documents in calculating the Yield Maintenance
Charge with respect to such principal prepayment; provided, however, that under no circumstances shall the Base
Interest Fraction be greater than 1.0 or less than zero. If such discount rate is greater than or equal to the lesser of (x) the
Mortgage Rate on the related Mortgage Loan or Serviced Whole Loan, as applicable, and (y) the Pass-Through Rate described in the
preceding sentence, then the Base Interest Fraction shall equal zero; provided that if such discount rate is greater than
or equal to the Mortgage Rate on such Mortgage Loan or Serviced Whole Loan, as applicable, but less than the Pass-Through Rate
described in the preceding sentence, then the Base Interest Fraction shall equal 1.0. If a Mortgage Loan provides for a step-up
in the Mortgage Rate, then the Mortgage Rate used in the determination of the Base Interest Fraction shall be the Mortgage Rate
in effect at the time of the prepayment.

 

For
purposes of the preceding paragraph, the relevant “Discount Rate” in connection with any Yield Maintenance
Charge collected on any prepaid Mortgage Loan or REO Loan and distributable on any Distribution Date shall be a rate per annum
equal to (i) if a discount rate was used in the calculation of the applicable Yield Maintenance Charge pursuant to the terms
of the relevant Mortgage Loan or REO Loan, as the case may be, such discount rate (as reported by the Master Servicer), converted
(if necessary) to a monthly equivalent yield, or (ii) if a discount rate was not used in the calculation of the applicable Yield
Maintenance Charge pursuant to the terms of the relevant Mortgage Loan or REO Loan, as the case may be, the yield calculated by
the linear interpolation of the yields (as reported under the heading “U.S. Government Securities/Treasury Constant Maturities”
in Federal Reserve Statistical Release H.15 (519) published by the Federal Reserve Board for the week most recently ended before
the date of the relevant prepayment (or deemed prepayment) of U.S. Treasury constant maturities with a maturity date, one longer
and one shorter, most nearly approximating the related Stated Maturity Date (in the case of a Mortgage Loan or REO Loan that is
not related to an ARD Loan) or the related Anticipated Repayment Date (in the case of a Mortgage Loan or REO Loan that is related
to an ARD Loan)), such interpolated yield converted to a monthly equivalent yield. If Federal Reserve Statistical Release H.15
(519) is no longer published, the Servicer shall select a comparable publication as the source of the applicable yields of U.S.
Treasury constant maturities, and the Servicer shall incur no liability with respect thereto. The Servicer shall notify the Certificate
Administrator in writing of its designation of an alternate index and the Certificate Administrator shall post same on its website
as a “special notice”.

 

(i)      No
Yield Maintenance Charge shall be distributed to the Holders of the Class X-E Regular Interest, Class E Regular Interest, Class
F Regular Interest, Class NR Regular Interest, Class R Certificates or Class Z Certificates. After the Certificate Balances and
Notional Amounts of the Class A-1 Regular Interest, Class A-2 Regular Interest, Class A-3 Regular Interest, Class A-4 Regular
Interest, Class A-5 Regular Interest, Class A-SB Regular Interest, Class X-A Regular Interest, Class X-B Regular Interest, Class
A-S Regular Interest, Class B Regular Interest, Class C Regular Interest and Class D Regular Interest have been reduced to zero,
Yield Maintenance Charges with respect to the Mortgage Loans shall be distributed to the Holder of the Class X-B Regular Interest.

 

    -332-

     

    

 

(ii)     All
distributions of Yield Maintenance Charges made (i) in respect of the respective Classes of Regular Interests on each Distribution
Date pursuant to Section 4.01(e) shall first be deemed to be distributed from the Lower-Tier REMIC to the Upper-Tier REMIC
in respect of the Lower-Tier Regular Interests, pro rata based upon the amount of principal distributed in respect of each
such Class of Lower-Tier Regular Interests for such Distribution Date pursuant to Section 4.01(c) above.

 

On
each Distribution Date, any Yield Maintenance Charges or Prepayment Premiums distributed in respect of:

 

(i)      the
Class A-1 Regular Interest shall be further allocated between and distributed on the Class A-1 Certificates, the Class V1-A Certificates

(f)         On
each Distribution Date, the Certificate Administrator shall determine if there will be any shortfalls in interest or principal
to any Class of Regular Interest that would occur on such Distribution Date without the inclusion of the Gain-on-Sale Remittance
Amount in the definition of “Available Funds” and shall remit all amounts on deposit in the Gain-on-Sale Reserve Account
to the Collection Account to be included as part of the applicable Available Funds. Upon termination of the Trust, any amounts
remaining in the Gain-on-Sale Reserve Account shall be distributed to the Holders of the Class R Certificates from the Lower-Tier
REMIC in respect of the Class LR Interest.

 

(g)        All
distributions made with respect to each Class of Certificates on each Distribution Date shall be allocated pro rata among
the outstanding Certificates in such Class based on their respective Percentage Interests. Except as otherwise specifically provided
in Sections 4.01(h), 4.01(i) and 9.01, all such distributions with respect to each Class on each Distribution
Date shall be made to the Certificateholders of the respective Class of record at the close of business on the related Record
Date and shall be made by wire transfer of immediately available funds to the account of any such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such Certificateholder shall have provided the Certificate Administrator
with written wiring instructions no less than five (5) Business Days prior to the related Record Date (which wiring instructions
may be in the form of a standing order applicable to all subsequent Distribution Dates), or otherwise by check mailed to such
Certificateholder at its address in the Certificate Register. The final distribution on each Certificate (determined without regard
to any possible future reimbursement of Realized Losses previously allocated to such Certificate) will be made in like manner,
but only upon presentation and surrender of such

 

    -334-

     

    

 

Certificate at the offices of the Certificate Registrar or such other location
specified in the notice to Certificateholders of such final distribution.

 

Each
distribution with respect to a Book-Entry Certificate shall be paid to the Depository, as Holder thereof, and the Depository shall
be responsible for crediting the amount of such distribution to the accounts of its Depository Participants in accordance with
its normal procedures. Each Depository Participant shall be responsible for disbursing such distribution to the Certificate Owners
that it represents and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating
firm”) for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Certificate Owners
that it represents. None of the Trustee, the Certificate Administrator, the Certificate Registrar, the Depositor, the Master Servicer,
the Special Servicer or the Underwriters shall have any responsibility therefor except as otherwise provided by this Agreement
or applicable law.

 

(h)        Except
as otherwise provided in Section 9.01, whenever the Certificate Administrator expects that the final distribution with
respect to any Class of Certificates (determined without regard to any possible future reimbursement of any amount of Realized
Losses previously allocated to such Class of Certificates) will be made on the next Distribution Date, the Certificate Administrator
shall, no later than the related P&I Advance Determination Date, post on the Certificate Administrator’s Website pursuant
to Section 3.13(b) a notice in electronic format to the effect that:

 

(i)         the
Certificate Administrator expects that the final distribution with respect to such Class of Certificates will be made on such
Distribution Date but only upon presentation and surrender of such Certificates at the offices of the Certificate Registrar or
such other location therein specified; and

 

(ii)         no
interest shall accrue on such Certificates from and after such Distribution Date.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 4.01(h) shall not have been surrendered for cancellation within six (6) months after the
time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining non-tendering Certificateholders
to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one
year after the second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator,
directly or through an agent, shall take such steps to contact the remaining non-tendering Certificateholders concerning the surrender
of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses
of holding such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable
to any Certificateholder on any amount held in trust hereunder by the Certificate

 

    -335-

     

    

 

Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 4.01(h).

 

(i)         Distributions
in reimbursement of Realized Losses previously allocated to the Regular Certificates shall be made in the amounts and manner specified
in Section 4.01(a), Section 4.01(b) or Section 4.01(d), as applicable, to the Holders of the respective Class
otherwise entitled to distributions of interest and principal on such Class on the relevant Distribution Date; provided
that all distributions in reimbursement of Realized Losses previously allocated to a Class of Certificates which has since been
retired shall be to the prior Holders that surrendered the Certificates of such Class upon retirement thereof and shall be made
by check mailed to the address of each such prior Holder last shown in the Certificate Register. Notice of any such distribution
to a prior Holder shall be made in accordance with Section 13.05 at such last address. The amount of the distribution to
each such prior Holder shall be based upon the aggregate Percentage Interest evidenced by the Certificates surrendered thereby.
If the check mailed to any such prior Holder is returned uncashed, then the amount thereof shall be set aside and held uninvested
in trust for the benefit of such prior Holder, and the Certificate Administrator shall attempt to contact such prior Holder in
the manner contemplated by Section 4.01(h) as if such Holder had failed to surrender its Certificates.

desirable, or that a Certificateholder or Certificate Owner reasonably requests, to enable Certificateholders to prepare their

(b)        [Reserved].

 

(c)        Each
of the Master Servicer and the Special Servicer may, at its sole cost and expense, make available by electronic media, bulletin
board service or Internet website (in addition to making information available as provided herein) any reports or other information
the Master Servicer or the Special Servicer, as applicable, is required or permitted to provide to any party to this Agreement,
the Rating Agencies or any Certificateholder or any prospective Certificateholder that has provided the Certificate Administrator,
the Master Servicer or the Special Servicer, as applicable, with an Investor Certification or has executed a “click-through”
confidentiality agreement in accordance with Section 3.13 hereof (which may be a licensed or registered investment advisor)
to the extent such action does not conflict with the terms of this Agreement (including without limitation, any requirements to
keep Privileged Information confidential), the terms of the Mortgage Loans or applicable law. Notwithstanding this paragraph,
the availability of such information or reports on the Internet or similar electronic media shall not be deemed to satisfy any
specific delivery requirements in this Agreement except as set forth herein. In connection with providing access to the Master
Servicer’s or Special Servicer’s Internet website, the Master Servicer or the Special Servicer, as applicable, shall
take reasonable measures to ensure that only such parties listed above may access such information including, without limitation,
requiring registration, a confidentiality agreement and acceptance of a disclaimer. The Master Servicer or the Special Servicer,
as applicable, shall not be liable for dissemination of this information in accordance with this Agreement, and neither the Master
Servicer nor the Special Servicer shall be responsible for any information delivered, produced, or made available pursuant to
Section 3.13 and 4.02(c), other than information produced by the Master Servicer or the Special Servicer, as applicable;
provided that such information otherwise meets the requirements set forth herein with respect to the form and substance
of such information or reports. The Master Servicer shall be entitled to attach to any report provided pursuant to this subsection,
any reasonable disclaimer with respect to information provided, or any assumptions required to be made by such report.

 

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

 

    -341-

     

    

 

Notwithstanding
the foregoing, the failure of the Master Servicer or the Special Servicer to disclose any information otherwise required to be
disclosed pursuant to this Section 4.02(c) or Section 4.02(d) shall not constitute a breach of this Section 4.02(c)
or of Section 4.02(d) to the extent the Master Servicer or the Special Servicer so fails because such disclosure, in
the reasonable belief of the Master Servicer or the Special Servicer, as the case may be, would violate any applicable law or
any provision of a Mortgage Loan document prohibiting disclosure of information with respect to the Mortgage Loans or the Mortgaged
Properties. The Master Servicer or the Special Servicer may affix to any information provided by it any disclaimer it deems appropriate
in its reasonable discretion (without suggesting liability on the part of any other party hereto).

 

(d)        Upon
the written request of a Certificateholder, any beneficial owner of a Certificate, or any prospective purchaser of a Certificate
that is a Qualified Institutional Buyer and is designated by a Certificateholder or a beneficial owner of a Certificate as such
and, in any case, has delivered an Investor Certification to the Depositor and the Certificate Administrator, as soon as reasonably
practicable, at the expense of the requesting party, the Certificate Administrator shall make available to the requesting party
such information that is in the Certificate Administrator’s possession or can reasonably be obtained by the Certificate
Administrator as is requested by such person, for purposes of satisfying applicable reporting requirements under Rule 144A under
the Securities Act. Neither the Certificate Registrar, nor the Certificate Administrator shall have any responsibility for the
sufficiency under Rule 144A or any other securities laws of any available information so furnished to any person including any
prospective purchaser of a Certificate or any interest therein, nor for the content or accuracy of any information so furnished
which was prepared or delivered to them by another.

 

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

 

(f)         Upon
the reasonable request of the Directing Holder or any Controlling Class Certificateholder that, in either case, is an Excluded
Controlling Class Holder with respect to any Excluded Controlling Class Loan identified to the Master Servicer’s (in the
case of a Non-Specially Serviced Loan) or the Special Servicer’s (in the case of a Specially Serviced Loan) reasonable satisfaction
(at the expense of the Directing Holder or such Controlling Class Certificateholder) and if such information is in the Master
Servicer’s or the Special Servicer’s possession, as applicable, the Master Servicer or the Special Servicer, shall
provide or make available (or forward electronically) to the Directing Holder or such Controlling Class Certificateholder, as
applicable, (at the expense of the Directing Holder or such Controlling Class Certificateholder, as applicable) any Excluded Information
(available to Privileged Persons through the Certificate Administrator’s Website but not accessible to the Directing Holder
or such Controlling Class Certificateholder on account of it constituting Excluded Information, as applicable, through the Certificate
Administrator’s Website because the Directing Holder or such Controlling Class Certificateholder, as applicable, is an Excluded
Controlling Class Holder with respect to another Excluded Controlling Class Loan) relating to any Excluded Controlling Class Loan
with respect to which the Directing Holder or such Controlling Class Certificateholder, as

 

    -342-

     

    

 

applicable, is not a Borrower Party;
provided that, in connection therewith, the Master Servicer or the Special Servicer may require a written confirmation
executed by the requesting Person substantially in such form as may be reasonably acceptable to the Master Servicer or the Special
Servicer, generally to the effect that such Person is the Directing Holder or a Controlling Class Certificateholder will keep
such Excluded Information confidential and is not a Borrower Party, upon which the Master Servicer or the Special Servicer may
conclusively rely. In addition, the Master Servicer and the Special Servicer shall be entitled to conclusively rely on delivery
from the Directing Holder or a Controlling Class Certificateholder, of an Investor Certification substantially in the form of
Exhibit P-1D that such Directing Holder or Controlling Class Certificateholder, is not an Excluded Controlling Class Holder
with respect to a particular Mortgage Loan. For the avoidance of doubt, the Special Servicer referenced in this Section 4.02(f)
shall include any applicable Excluded Special Servicer with respect to the related Excluded Special Servicer Loan(s).

 

Section
4.03    P&I Advances. (a) On or before 4:00 p.m., New York City time, on each P&I Advance Date,
the Master Servicer shall (i) remit to the Certificate Administrator for deposit from its own funds into the Lower-Tier REMIC
Distribution Account, an amount equal to the aggregate amount of P&I Advances, if any, with respect to the Mortgage Loans
to be made in respect of the related Distribution Date to be made in respect of the related Distribution Date, (ii) apply amounts
held in the Collection Account, for future distribution to Certificateholders in subsequent months in discharge of any such obligation
to make P&I Advances or (iii) make P&I Advances in the form of any combination of (i) and (ii) aggregating the total amount
of P&I Advances to be made. Any amounts held in the Collection Account for future distribution and so used to make P&I
Advances with respect to the Mortgage Loans shall be appropriately reflected in the Master Servicer’s records and replaced
by the Master Servicer by deposit in the Collection Account on or before the next succeeding P&I Advance Date (to the extent
not previously replaced through the deposit of Late Collections of the delinquent principal and/or interest in respect of which
P&I Advances were made). The Master Servicer shall notify the Certificate Administrator of (i) the aggregate amount of P&I
Advances with respect to the Mortgage Loans and any REO Mortgage Loans for a Distribution Date and (ii) the amount of any Nonrecoverable
P&I Advances with respect to the Mortgage Loans and any REO Mortgage Loans for such Distribution Date. If the Master Servicer
fails to make a required P&I Advance by 4:00 p.m., New York City time, on any P&I Advance Date, the Trustee shall make
such P&I Advance pursuant to Section 7.05 by noon, New York City time, on the related Distribution Date, unless the
Master Servicer shall have cured such failure (and provided written notice of such cure to the Trustee and the Certificate Administrator)
by 11:00 a.m., New York City time, on such Distribution Date. In the event that the Master Servicer fails to make a required P&I
Advance hereunder, the Certificate Administrator shall notify the Trustee of such circumstances by 4:30 p.m., New York City time,
on the related P&I Advance Date. Notwithstanding the foregoing, the portion of any P&I Advance equal to the CREFC®
Intellectual Property Royalty License Fee for the related Mortgage Loans and any REO Mortgage Loans shall not be remitted
to the Certificate Administrator for deposit into the Lower-Tier REMIC Distribution Account but shall be deposited into the Collection
Account for payment to CREFC® on such Distribution Date.

 

(b)        Subject
to Section 4.03(c) and Section 4.03(e) below, the amount of P&I Advances to be made by the Master Servicer with
respect to any Distribution Date and all

 

    -343-

     

    

 

Mortgage Loans and REO Mortgage Loans, shall be equal to: (i) the Periodic Payments (net
of related Servicing Fees and, in the case of any Non-Serviced Mortgage Loan, a fee accruing at the related Non-Serviced Primary
Servicing Fee Rate) other than Balloon Payments, that were due on the Mortgage Loans (including any Non-Serviced Mortgage Loan)
and any REO Loan (excluding any portion of an REO Loan related to any Companion Loan) during the related Collection Period and
delinquent as of the close of business on the Business Day preceding the related P&I Advance Date (or not advanced by any
Sub-Servicer on behalf of the Master Servicer) and (ii) with respect to each Mortgage Loan delinquent in respect of its Balloon
Payment as of the close of business on the Business Day preceding the related P&I Advance Date (including any REO Loan (but
excluding any portion of an REO Loan related to any Companion Loan) as to which the related Balloon Payment would have been past
due), an amount equal to the Assumed Scheduled Payment (net of any collections of previously unadvanced principal and interest
(adjusted to the related Net Mortgage Rate) received with respect to such Mortgage Loan or REO Loan, as applicable, during the
related Collection Period) therefor. Subject to subsection (c) below, the obligation of the Master Servicer to make such
P&I Advances is mandatory, and with respect to any Mortgage Loan (including any Non-Serviced Mortgage Loan) or REO Loan (but
excluding any portion of an REO Loan related to any Companion Loan), shall continue until the Distribution Date on which the proceeds,
if any, received in connection with a Liquidation Event or the disposition of the REO Property, as the case may be, with respect
thereto are to be distributed. Neither the Master Servicer nor the Trustee shall make or be permitted to make any P&I Advances
with respect to any Companion Loan. The Special Servicer shall not make any P&I Advances on any Mortgage Loan or Companion
Loan.

 

(c)        Notwithstanding
anything herein to the contrary, no P&I Advance shall be required to be made hereunder if such P&I Advance would, if made,
constitute a Nonrecoverable P&I Advance. With respect to each Non-Serviced Mortgage Loan, the Master Servicer will be required
to make its determination (based on information provided by the applicable Non-Serviced Master Servicer and Non-Serviced Special
Servicer) that it has made a P&I Advance on such Non-Serviced Mortgage Loan that is a Nonrecoverable Advance or that any proposed
P&I Advance would, if made, constitute a Nonrecoverable Advance with respect to such Non-Serviced Mortgage Loan independently
of any determination made by the applicable Non-Serviced Master Servicer or the applicable Non-Serviced Special Servicer, as the
case may be, under the applicable Non-Serviced PSA in respect of the related Non-Serviced Companion Loan. If the Master Servicer
or the Special Servicer determines that a proposed P&I Advance with respect to a Non-Serviced Mortgage Loan, if made, or any
outstanding P&I Advance with respect to a Non-Serviced Mortgage Loan previously made, would be, or is, as applicable, a Nonrecoverable
Advance, the Master Servicer shall provide the applicable Non-Serviced Master Servicer and Non-Serviced Special Servicer written
notice of such determination within two (2) Business Days of the date of such determination. If the Master Servicer receives written
notice from the related Non-Serviced Master Servicer or the related Non-Serviced Special Servicer, as the case may be, that either
has determined in accordance with the applicable Non-Serviced PSA with respect to a Non-Serviced Companion Loan, that any proposed
advance under the applicable Non-Serviced PSA that is similar to a P&I Advance would be, or any outstanding advance under
such Non-Serviced PSA that is similar to a P&I Advance is, a nonrecoverable advance, then the Master Servicer or the Trustee
may, based upon such determination, determine that any P&I Advance previously made or proposed to be made with respect to
the related

 

    -344-

     

    

 

Non-Serviced Mortgage Loan, will be a Nonrecoverable P&I Advance. Thereafter, in either case, the Master Servicer
shall not be required to make any additional P&I Advances with respect to the related Non-Serviced Mortgage Loan unless and
until the Master Servicer or the Trustee, as the case may be, determines that any such additional P&I Advances with respect
to the related Non-Serviced Mortgage Loan would not be a Nonrecoverable P&I Advance, which determination may be as a result
of consultation with the related Non-Serviced Master Servicer or the related Non-Serviced Special Servicer, as the case may be,
or otherwise.

 

(d)        In
connection with the recovery of any P&I Advance out of the Collection Account, pursuant to Section 3.05(a), the Master
Servicer shall be entitled to pay the Trustee and itself (in that order of priority) as the case may be, out of any amounts then
on deposit in the Collection Account (but in no event from any funds allocable to a Serviced Companion Noteholder (unless related
thereto), except to the extent permitted pursuant to the terms of the related Intercreditor Agreement), interest at the Reimbursement
Rate in effect from time to time, accrued on the amount of such P&I Advance from the date made to but not including the date
of reimbursement; provided, however, that no interest will accrue on any P&I Advance (i) made with respect to
a Mortgage Loan until after the related Due Date has passed and any applicable Grace Period has expired or (ii) if the related
Periodic Payment is received after the Determination Date but on or prior to the related P&I Advance Date. The Master Servicer
shall reimburse itself and/or the Trustee, as the case may be, for any outstanding P&I Advance, subject to Section 3.17
of this Agreement, as soon as practicably possible after funds available for such purpose are deposited in the Collection
Account.

 

(e)        Notwithstanding
the foregoing, (i) neither the Master Servicer nor the Trustee shall make an advance for Excess Interest, Yield Maintenance Charges,
Default Interest, late payment charges, Balloon Payment or any P&I Advance with respect to any Companion Loan and (ii) if
an Appraisal Reduction Amount has been determined to exist with respect to any Mortgage Loan (or, in the case of a Non-Serviced
Whole Loan, an “appraisal reduction amount” (or similar item has been made in accordance with the related Non-Serviced
PSA and the Master Servicer has notice of such appraisal reduction amount), then in the event of subsequent delinquencies thereon,
the interest portion of the P&I Advance in respect of such Mortgage Loan for the related Distribution Date shall be reduced
(it being herein acknowledged that there shall be no reduction in the principal portion of such P&I Advance) to equal the
product of (x) the amount of the interest portion of such P&I Advance for such Mortgage Loan for such Distribution Date without
regard to this clause 4.03(e)(ii), and (y) a fraction, expressed as a percentage, the numerator of which is equal to the
Stated Principal Balance of such Mortgage Loan immediately prior to such Distribution Date, net of the related Appraisal Reduction
Amount (or, in the case of a Serviced Whole Loan, the portion of such Appraisal Reduction Amount allocated to the related Mortgage
Loan), if any, and the denominator of which is equal to the Stated Principal Balance of such Mortgage Loan immediately prior to
such Distribution Date. For purposes of the immediately preceding sentence, the Periodic Payment due on the Maturity Date for
a Balloon Mortgage Loan will be the Assumed Scheduled Payment for the related Distribution Date.

 

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

Section
4.04     Allocation of Realized Losses.

 

(a)       On
each Distribution Date, immediately following the distributions to be made on such date pursuant to Section 4.01, the Certificate
Administrator shall calculate the amount, if any, by which (i) the aggregate Stated Principal Balance (for purposes of this definition
only, not giving effect to any reductions of the Stated Principal Balance for payments of principal collected on the Mortgage
Loans that were used to reimburse any Workout-Delayed Reimbursement Amounts pursuant to Section 3.05(a)(v) to the extent
such Workout-Delayed Reimbursement Amounts are not otherwise determined to be Nonrecoverable Advances) of the Mortgage Loans and
any REO Loans (excluding any portion allocable to any related Companion Loan) expected to be outstanding immediately following
such Distribution Date, is less than (ii) the then-aggregate Certificate Balance of the Regular Interests after giving effect
to distributions of principal on such Distribution Date (any such deficit, the “Realized Loss”). Any allocation
of Realized Losses to a Class of Regular Interests shall be made by reducing the Certificate Balance thereof by the amount so
allocated. The allocation of Realized Losses shall constitute an allocation of losses and other shortfalls experienced by the
Trust. Reimbursement of previously allocated Realized Losses will not constitute distributions of principal for any purpose and
will not result in an additional reduction in the Certificate Balance of the applicable Regular Interest in respect of which any
such reimbursement is made. With respect to any Regular Interest (other than any Class X Regular Interest), to the extent any
Nonrecoverable Advances (plus interest thereon) that were reimbursed from principal collections on the Mortgage Loans and previously
resulted in a reduction of the Principal Distribution Amount are subsequently recovered on the related Mortgage Loan, the amount
of such recovery will be added to the Certificate Balance of the Class or Classes of Regular Interest that previously were allocated
Realized Losses and in the case of Realized Losses, in sequential order according to the priority of payments for the Regular
Interests (other than the Class X Regular Interests) (and in the case of the Class A-1, Class A-2, Class A-3, Class A-4, Class
A-5 and Class A-SB Regular Interests, on a pro rata basis according to the amount of unreimbursed Realized Losses on such
Classes), in each case up to the amount of the unreimbursed Realized Losses allocated to such Class of Regular Interest.

 

(b)       (i)
On each Distribution Date, the Certificate Balances of each Regular Interest (other than the Class X Regular Interests) will be
reduced without distribution, as a write-off to the extent of any Realized Losses, if any, allocable to such Certificates with
respect to such Distribution Date. Any such write-off shall be allocated first, to the Class NR Regular Interest, second,
to the Class F Regular Interest, third, to the Class E Regular Interest, fourth, to the Class D Regular Interest,
fifth, to the Class C Regular Interest, sixth, to the Class B Regular Interest, seventh, to the Class A-S
Regular Interest, and then, pro rata (based on their respective Certificate Balances), Class A-1, Class A-2, Class
A-3, Class A-4, Class A-5 and Class A-SB Regular Interests, in each case until the remaining Certificate Balances of such Regular
Interests have been reduced to zero.

 

(ii)       Any
such write-offs in respect of:

 

(A)      the
Class A-1 Regular Interest shall be further allocated to the Class A-1 Certificates, the Class V1-A Certificates and the Class

to

respect to any Distribution Date, any Realized Losses allocated to a Class of Regular Interests pursuant to Section

the Related Lower-Tier Regular Interest with respect thereto as a write-off.

 

Section
4.05     Appraisal Reduction Amounts; Collateral Deficiency Amounts. (a) For purposes of (x) determining
the Non-Reduced Regular Interests and the Controlling Class (and whether a Control Termination Event has occurred and is continuing)
and (y) determining the Voting Rights of the related Classes for purposes of removal of the Special Servicer or the Operating
Advisor, Appraisal Reduction Amounts (with respect to a Serviced Whole Loan, to the extent allocated to the related Mortgage Loan)
shall be allocated to each Regular Interest (other than the Class X Regular Interests) in reverse sequential order to notionally
reduce the related Certificate Balances until the Certificate Balance of each such Class is reduced to zero (i.e., first,
to the Class NR Regular Interest, second, to the Class F Regular Interest, third, to the Class E Regular Interest,
fourth, to the Class D Regular Interest, fifth, to the Class C Regular Interest, sixth, to the Class B Regular
Interest, seventh, to the Class A-S Regular Interest, and finally, pro rata based on their respective Certificate

As
of the first Determination Date following a Mortgage Loan (other than a Non-Serviced Mortgage Loan) becoming an AB Modified
Loan, the Special Servicer shall calculate whether a Collateral Deficiency Amount exists with respect to such AB Modified
Loan, taking into account the most recent Appraisal obtained by the Special Servicer with respect to such Mortgage Loan, and
all other information relevant to a Collateral Deficiency Amount determination. Upon obtaining knowledge or receiving notice
by the Special Servicer that a Non-Serviced Mortgage Loan has become an AB Modified Loan, the Special Servicer shall (i)
promptly request from the related Non-Serviced Master Servicer, Non-Serviced Special Servicer and Non-Serviced Trustee the
most recent appraisal with respect to such AB Modified Loan, in addition to all other information reasonably required by the
Special Servicer to calculate whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan, and (ii)
as of the first Determination Date following receipt by the Special Servicer of the appraisal and any other information set
forth in the immediately preceding clause (i) that the Special Servicer reasonably expects to receive, calculate
whether a Collateral Deficiency Amount exists with respect to such AB Modified Loan, taking into account the most recent
appraisal obtained by the Non-Serviced Special Servicer with respect to such Non-Serviced Mortgage Loan, and all other
information relevant to a Collateral Deficiency Amount determination. Upon obtaining knowledge or receipt of notice by any
other party to this Agreement that a Non-Serviced Mortgage Loan has become an AB Modified Loan, such party shall promptly
notify the Special Servicer thereof. The Master Servicer, upon reasonable prior written request, shall provide the Special
Servicer with information in its possession that is reasonably required to calculate or recalculate any Collateral Deficiency
Amount. The Master Servicer shall use reasonable efforts to assist the Special Servicer in obtaining information reasonably
required to calculate or recalculate any Collateral Deficiency Amount with respect to a Non-Serviced Mortgage Loan in the
event that the Special Servicer is unsuccessful in obtaining such information from the related Non-Serviced Master Servicer,
Non-Serviced Special Servicer or Non-Serviced Trustee. None of the Master Servicer, the Trustee or the Certificate
Administrator shall calculate or verify any Collateral Deficiency Amount.

 

For
purposes of determining the Controlling Class and whether a Control Termination Event has occurred and is continuing, Collateral
Deficiency Amounts allocated to a related Mortgage Loan that is an AB Modified Loan will be allocated to each Class of Control
Eligible Corresponding Certificates in reverse sequential order to notionally reduce the related Certificate Balances until the
Certificate Balance of each such Class of Control Eligible Corresponding Certificates is reduced to zero (i.e., first,
to the Class NR Certificates, second, to the Class F Certificates, and third, to the Class E Certificates). For
the avoidance of doubt, for purposes of determining the Controlling Class or the occurrence and continuance of a Control Termination
Event, any Class of Control Eligible Corresponding Certificates shall be allocated both applicable Appraisal Reduction Amounts
and applicable Collateral Deficiency Amounts (the sum of which shall constitute the applicable Cumulative Appraisal Reduction
Amount), in accordance with this Section 4.05(a).

 

With
respect to (i) any Appraisal Reduction Amount calculated for the purposes of determining the Non-Reduced Certificates or determining
the Voting Rights of the related

 

    -350-

     

    

 

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

 

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

 

(b)       (i)
The Holders of the majority of Voting Rights of any Class of Control Eligible Corresponding Certificates that is determined at
any time of determination to no longer be the Controlling Class (any such Class, an “Appraised-Out Class”)
as a result of an Appraisal Reduction Amount or Collateral Deficiency Amount (as applicable) in respect of such Class shall have
the right, at their sole expense, to require the Special Servicer to order a second Appraisal with respect to any Mortgage Loan
(or Serviced Whole Loan) for which an Appraisal Reduction Event has occurred or as to which there exists a Collateral Deficiency
Amount (such Holders, the “Requesting Holders”). The Special Servicer shall use its reasonable best efforts
to ensure that such second Appraisal is delivered within thirty (30) days from receipt of the Requesting Holders’ written
request and shall ensure that such Appraisal is prepared on an “as-is” basis by an MAI appraiser (provided
that such MAI appraiser may not be the same MAI appraiser that provided the Appraisal in respect of which the Requesting Holders
are requesting the Special Servicer to obtain an additional Appraisal).

 

(ii)       Upon
receipt of any supplemental Appraisal pursuant to clause (i) above, the Special Servicer shall determine, in accordance
with the Servicing Standard, whether, based on its assessment of such supplemental Appraisal, any recalculation of the Appraisal
Reduction Amount or Collateral Deficiency Amount (as applicable) is warranted, and if so warranted, the Special Servicer shall
recalculate the Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable, based on such supplemental appraisal.
If required by such recalculation, the Appraised-Out Class shall be reinstated as the Controlling Class and each other Appraised-Out
Class shall, if applicable, have its related

 

    -351-

     

    

 

Certificate
Balance notionally restored to the extent required by such recalculation of the Appraisal Reduction Amount or Collateral Deficiency
Amount, if applicable. In addition, the Requesting Holders of any Appraised-Out Class shall have the right, at their sole expense,
to require the Special Servicer to order an additional appraisal of any Mortgage Loan for which an Appraisal Reduction Event has
occurred or as to which there exists a Collateral Deficiency Amount if an event has occurred at or with regard to the related
Mortgaged Property or Mortgaged Properties that would have a material effect on its appraised value, and the Special Servicer
shall use its reasonable efforts to obtain such appraisal from an MAI appraiser reasonably acceptable to the Special Servicer
within thirty (30) days from receipt of the Requesting Holders’ written request; provided, that the Special Servicer
shall not be required to obtain such appraisal if it determines in accordance with the Servicing Standard that no events at or
with regard to the related Mortgaged Property or Mortgaged Properties have occurred that would have a material effect on the appraised
value of the related Mortgaged Property or Mortgaged Properties. The Holders of an Appraised-Out Class requesting any supplemental
Appraisal pursuant to clause (i) above shall refrain from exercising any direction, control, consent and/or similar rights
of the Controlling Class until such time, if any, as the Class is reinstated as the Controlling Class (such period beginning upon
receipt by the Special Servicer of any request to obtain a supplemental Appraisal pursuant to clause (i) above to but excluding
the date on which either (A) the Special Servicer determines that no recalculation of the Appraisal Reduction Amount or Collateral
Deficiency Amount (as applicable) is warranted or (B) the Special Servicer recalculates the Appraisal Reduction Amount or Collateral
Deficiency Amount (as applicable) based on the supplemental Appraisal, the “Appraisal Review Period”). The
rights of the Controlling Class during each Appraisal Review Period shall be exercised by the most senior Class of Control Eligible
Corresponding Certificates, if any.

 

(c)       With
respect to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) and any Serviced Whole Loan as to which an Appraisal Reduction
Event has occurred (unless such Mortgage Loan or Serviced Whole Loan has remained current for three consecutive Periodic Payments,
and with respect to which no other Appraisal Reduction Event has occurred with respect to that Mortgage Loan during the preceding
three months (for such purposes taking into account any amendment or modification of such Mortgage Loan, any related Companion
Loan or Serviced Whole Loan)), the Special Servicer shall (1) within thirty (30) days of the occurrence or of each anniversary
of the related Appraisal Reduction Event, and (2) upon its determination that the value of the related Mortgaged Property has
materially changed, notify the Master Servicer of the occurrence of such anniversary or determination and order an Appraisal (which
may be an update of a prior Appraisal), the cost of which shall be paid by the Master Servicer as a Servicing Advance or to the
extent it would be a Nonrecoverable Advance, an expense of the Trust, or conduct an internal valuation, as applicable, and promptly
following receipt of any such Appraisal or performance of such valuation (or receipt of any Appraisal obtained in accordance with
Section 4.05(b) above), shall promptly deliver a copy thereof to the Master Servicer, the Certificate Administrator, the
Trustee, the Operating Advisor and ((i) prior to the occurrence and continuance of any Consultation Termination Event and (ii)
other than with respect to any Mortgage Loan that is an Excluded Loan with respect to the Directing Holder or, if the Directing
Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class) the Directing Holder; provided,
however, that no new or updated appraisal

 

    -352-

     

    

 

shall
be required if the Mortgage Loan, Serviced Whole Loan or REO Property is under contract to be sold within ninety (90) days of
such Appraisal Reduction Event or anniversary thereof and the Special Servicer reasonably believes such sale is likely to close.
Based upon such Appraisal or internal valuation (or any Appraisal obtained in accordance with Section 4.05(b) above) and
receipt of information reasonably requested by the Special Servicer from the Master Servicer necessary to calculate the Appraisal
Reduction Amount that is either in the Master Servicer’s possession or reasonably obtainable by the Master Servicer, the
Special Servicer shall determine or redetermine, as applicable, and report to the Master Servicer, the Certificate Administrator,
the Trustee, the Operating Advisor and ((i) prior to the occurrence and continuance of any Consultation Termination Event and
(ii) other than with respect to any Mortgage Loan that is an Excluded Loan as to such party) the Directing Holder, the amount
and calculation or recalculation of the Appraisal Reduction Amount or Collateral Deficiency Amount with respect to such Mortgage
Loan, Companion Loan or Serviced Whole Loan, as applicable, and such report shall be delivered in the CREFC® Appraisal
Reduction Amount Template format; provided, however, that the Special Servicer shall not be liable for failure to
comply with such duties insofar as such failure results from a failure of the Master Servicer to provide sufficient information
to the Special Servicer to comply with such duties or failure by the Master Servicer to otherwise comply with its obligations
hereunder. Such report shall also be forwarded by the Master Servicer (or the Special Servicer if the related Mortgage Loan is
a Specially Serviced Loan), to the extent the related Serviced Companion Loan has been included in an Other Securitization, to
the Other Servicer, to the extent required by the related Intercreditor Agreement, of such Other Securitization into which the
related Serviced Companion Loan has been sold, or to the holder of any related Serviced Companion Loan by the Master Servicer
(or the Special Servicer if the related Mortgage Loan is a Specially Serviced Loan). If the Special Servicer is required to redetermine
the Appraisal Reduction Amount or Collateral Deficiency Amount, such redetermined Appraisal Reduction Amount or Collateral Deficiency
Amount shall replace the prior Appraisal Reduction Amount or Collateral Deficiency Amount, as applicable, with respect to such
Mortgage Loan, Companion Loan or Serviced Whole Loan, as applicable. Prior to the occurrence and continuance of a Consultation
Termination Event (and unless the related Mortgage Loan is an Excluded Loan as to such party), the Special Servicer shall consult
with the Directing Holder with respect to any Appraisal, valuation or downward adjustment in connection with an Appraisal Reduction
Amount or Collateral Deficiency Amount. Notwithstanding the foregoing but subject to Section 4.05(b), the Special Servicer
shall not be required to obtain an Appraisal or conduct an internal valuation, as applicable, with respect to a Mortgage Loan
or related Companion Loan or Serviced Whole Loan as to which an Appraisal Reduction Event has occurred to the extent the Special
Servicer has obtained an Appraisal or conducted such a valuation (in accordance with requirements of this Agreement), as applicable,
with respect to the related Mortgaged Property within the six-month period immediately prior to the occurrence of such Appraisal
Reduction Event. Instead, the Special Servicer may use such prior Appraisal or valuation, as applicable, in calculating any Appraisal
Reduction Amount or Collateral Deficiency Amount with respect to such Mortgage Loan or related Companion Loan or Serviced Whole
Loan; provided that the Special Servicer is not aware of any material change to the related Mortgaged Property having occurred
and affecting the validity of such Appraisal or valuation.

 

The
Master Servicer shall deliver by electronic mail to the Special Servicer any information in its possession reasonably required
to determine, calculate, redetermine or

 

    -353-

     

    

 

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

 

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

 

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

 

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

 

    -354-

     

    

 

respect
to the related Specific Grantor Trust Assets in the time or times and in the manner required by the Code.

 

(b)       The
Grantor Trust will be treated as a WHFIT that is a WHMT. The Certificate Administrator will report as required under the WHFIT
Regulations to the extent such information as is reasonably necessary to enable the Certificate Administrator to do so is provided
to the Certificate Administrator on a timely basis. The Certificate Administrator is hereby directed to assume that DTC is the
only “middleman” as defined by the WHFIT Regulations unless the Depositor provides the Certificate Administrator with
the identities of other “middlemen” that are Certificateholders. The Certificate Administrator shall be entitled to
rely on the first sentence of this Section 4.06(b) and shall be entitled to indemnification in accordance with the terms
of this Agreement in the event that the Internal Revenue Service makes a determination that the first sentence of this paragraph
is incorrect.

 

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

 

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

 

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

 

Section
4.07     Investor Q&A Forum; Investor Registry; and Rating Agency Q&A Forum and Document Request

Servicer, the Special Servicer or the Operating Advisor determines, in its respective sole discretion, that (i) any Inquiry is

the Certificateholders, (iii) answering any Inquiry would be in violation of applicable law, the applicable Mortgage Loan documents

deemed to be answers from any of the Depositor, the Underwriters or any of their respective Affiliates. None of the Underwriters,

of their respective Affiliates will certify to any of the information posted in the Investor Q&A Forum and no such party shall

the Operating Advisor shall not be required to respond to any Inquiries from Certificateholders for which its response would require
the Operating Advisor to provide information to such inquiring Certificateholders that they are otherwise not entitled to receive
under the terms of this Agreement.

 

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

(c)       The
17g-5 Information Provider shall make available, only to NRSROs, the Rating Agency Q&A Forum and Document Request Tool. The

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 the case of the Master Servicer to
the following: Surveillance_Inquiries@keybank.com), in each case within a commercially reasonable period of time following receipt
thereof. Following receipt of a Rating Agency Inquiry from the 17g-5 Information Provider, the Master Servicer or the Special
Servicer, as applicable, unless it determines not to answer such Rating Agency Inquiry as provided below, shall reply by email
to the Certificate Administrator. The 17g-5 Information Provider shall post (within a commercially reasonable period of time following

inquiry may be posted on a separate website or web page accessible by a link on the 17g-5 Information Provider’s Website.

(i) answering any Rating Agency Inquiry would be in violation of applicable law, the Servicing Standard, this Agreement or any
Mortgage Loan documents, (ii) answering any Rating Agency Inquiry would or is reasonably expected to result in a waiver of an
attorney-client privilege with, or the disclosure of attorney work product, or (iii) (A) answering any Rating Agency Inquiry would
materially increase the duties of, or result in significant additional cost or expense to, the Certificate Administrator, the
Master Servicer or the Special Servicer, as applicable, and (B) the Certificate Administrator, the Master Servicer or the Special
Servicer, as applicable, determines in accordance with the Servicing Standard (or in good faith, in the case of the Certificate
Administrator) that the performance of such duties or the payment of such costs and expenses is beyond the scope of its duties
in its capacity as Certificate Administrator, Master Servicer or the Special Servicer, as applicable, under this Agreement, it
shall not be required to answer such Rating Agency Inquiry and shall promptly notify the 17g-5 Information Provider by email of
such determination. The 17g-5 Information Provider shall promptly thereafter post the Rating Agency Inquiry with the reason it
was not answered to the Rating Agency Q&A Forum and Document Request Tool. The 17g-5 Information Provider shall not be liable
for the failure by any other such Person to so answer. Questions posted on the Rating Agency Q&A Forum and Document Request
Tool shall not be attributed to the submitting NRSRO. Answers posted on the Rating Agency Q&A Forum and Document Request Tool

Section
4.08     Secure Data Room. (a) The Certificate Administrator shall create a Secure Data Room within
120 days following the Closing Date. The Depositor shall upon the receipt of each Mortgage Loan Seller’s Diligence File
Certificate, deliver to the Certificate Administrator within 120 days following the Closing Date, an electronic copy of the Diligence
Files for the Mortgage Loans that have been uploaded by the Mortgage Loan Sellers to the Designated Site. Upon receipt thereof,
the Certificate Administrator shall promptly upload the contents of each Diligence File actually received by it to the Secure
Data Room. Access to the Secure Data Room shall be granted by the Certificate Administrator to (i) the Asset Representations Reviewer
and (ii) provided that the Certificate Administrator has received the Diligence File Certificate from each Mortgage Loan Seller
pursuant to Section 2.01(h), any other Person at the direction of the Depositor, in each case, upon the occurrence of an
Affirmative Asset Review Vote and receipt by the Certificate Administrator of a certification substantially in the form of Exhibit
RR hereto (which shall be sent via email to trustadministrationgroup@wellsfargo.com or submitted electronically via the Certificate
Administrator’s Website). In no case whatsoever shall Certificateholders be permitted to access the Secure Data Room. For
the avoidance of doubt, the Certificate Administrator shall be under no obligation to post any documents or information to the
Secure Data Room other than the contents of the Diligence Files initially delivered to it by the Depositor.

 

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

 

(c)       Upon
the resignation or removal of the Certificate Administrator pursuant to Section 8.07, the Certificate Administrator shall
transfer electronic copies of the Diligence

 

    -359-

     

    

 

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

5.01      The Certificates. (a) The Certificates will be substantially in the respective forms
annexed hereto as Exhibits A-1 through and including A-25, with such appropriate insertions, omissions, substitutions
and other variations as are required or permitted by this Agreement or as may, in the reasonable judgment of the Certificate Registrar,
be necessary, appropriate or convenient to comply, or facilitate compliance, with applicable laws, and may have such letters,
numbers or other marks of identification and such legends or endorsements placed thereon as may be required by law, or as may,
consistently herewith, be determined by the officers executing such Certificates, as evidenced by their execution thereof. The
Class X-A Certificates and Class X-B Certificates will be issuable only in minimum Denominations of authorized initial Notional
Amount of not less than $1,000,000 and in integral multiples of $1.00 in excess thereof. The Class X-E Certificates will be issuable
only in minimum Denominations of authorized initial Notional Amount of not less than $500,000 and in integral multiples of $1.00
in excess thereof. The Offered Certificates (other than the Class X-A Certificates and Class X-B Certificates) will be issuable
only in minimum Denominations of authorized initial Certificate Balance of not less than $10,000, and in integral multiples of
$1.00 in excess thereof. The Non-Registered Certificates (other than the Class X-E, Class V, Class Z and Class R Certificates)
will be issuable in minimum Denominations of authorized initial Certificate Balance of not less than $100,000, and in integral
multiples of $1.00 in excess thereof. If the Original Certificate Balance or initial Notional Amount, as applicable, of any Class

of authorized initial Certificate Balance or initial Notional Amount, as applicable, that includes the excess of (i) the Original
Certificate Balance or initial Notional Amount, as applicable, of such Class over (ii) the largest integral multiple of $1.00
that does not exceed such amount. The Certificates of each Class of Class V Certificates will be issuable in one or more Definitive

shall be issued, maintained and transferred in minimum percentage interests of 10% of such Class R Certificates and in integral

interests of 1% of such Class Z Certificates.

 

(b)       One
authorized signatory shall sign the Certificates for the Certificate Registrar by manual or facsimile signature. If an authorized
signatory whose signature is on a Certificate no longer holds that office at the time the Certificate Registrar countersigns the
Certificate, the Certificate shall be valid nevertheless. A Certificate shall not be valid until an authorized signatory of the
Certificate Registrar (who may be the same officer who executed the Certificate) manually countersigns the Certificate. The signature
shall be conclusive evidence that the Certificate has been executed and countersigned under this Agreement.

 

(c)       During
the Transfer Restriction Period, the HRR Certificates shall only be held as Definitive Certificates in the Third Party Purchaser
Safekeeping Account by the Certificate Administrator (and the Holder of the HRR Certificates shall be registered on the Certificate
Register), unless otherwise consented to by the Retaining Sponsor. The Certificate Administrator shall hold the HRR Certificates
in safekeeping and shall release the same only upon receipt of written instructions in accordance with this agreement from the
Holder of the HRR Certificates and the Retaining Sponsor’s consent (subject to Section 5.01(d)), and in accordance with
any authentication procedures as may be utilized by the Certificate Administrator. There shall be, and hereby is, established
by the Certificate Administrator an account which shall be designated the “Third Party Purchaser Safekeeping Account”
and into which the HRR Certificates shall be held and which shall be governed by and subject to this Agreement and the Credit
Risk Retention Compliance Agreement. The HRR Certificates to be delivered in physical form to the Certificate Administrator shall
be delivered as set forth herein. Unless otherwise directed by the Retaining Sponsor, no amounts distributable to the HRR Certificates
shall be remitted to the Third Party Purchaser Safekeeping Account but shall be remitted directly to the Holder of the HRR Certificates
in accordance with written instructions (which shall be in the form of Exhibit VV to this Agreement) provided separately
by the Holder of the HRR Certificates to the Certificate Administrator. Under no circumstances by virtue of safekeeping the HRR
Certificates shall the Certificate Administrator (i) be obligated to bring legal action or institute proceedings against any person
on behalf of the Holder of the HRR Certificates or the Retaining Sponsor or (ii) have any obligation to monitor, supervise or
enforce the performance of any party under the related Credit Risk Retention Compliance Agreement. The Certificate Administrator
shall be entitled to conclusively rely with no obligation to verify, confirm or otherwise monitor the accuracy of any information
included in any written instructions provided in connection with the Third Party Purchaser Safekeeping Account and shall have
no liability in connection therewith, other than with respect to the Certificate Administrator’s obligation to obtain the
Retaining Sponsor’s consent prior to any release of the HRR Certificates. During the Transfer Restriction Period, the Certificate
Administrator shall hold the Definitive Certificate representing the HRR Certificates at the location below, or any other location;
provided the Certificate Administrator has given notice to the Holder of the HRR Certificates of such new location:

On
the Closing Date, the Certificate Administrator shall deliver written confirmations to the Depositor, the Retaining Sponsor and
the Third Party Purchaser substantially in the form of Exhibit UU to this Agreement evidencing its receipt of the HRR Certificates
and to the Depositor.

 

The
Certificate Administrator shall make available to the Holder of the HRR Certificates and the Retaining Sponsor a statement of
the Third Party Purchaser Safekeeping Account as mutually agreed upon by the Certificate Administrator, the Retaining Sponsor
and the Holder of the HRR Certificates, and in accordance with the Certificate Administrator’s policies and procedures.
Any transfer of the HRR Certificates shall be subject to ARTICLE V of this Agreement.

 

(d)       In
the event the Third Party Purchaser seeks to cause the release of any HRR Certificates from the Third Party Safekeeping Account,
the Third Party Purchaser shall simultaneously deliver to the Certificate Administrator, the Retaining Sponsor and the Depositor
(i) an executed written request for such release in the form attached hereto as Exhibit D-5 and (ii) an executed written
request for the Retaining Sponsor’s consent to such release substantially in the form attached hereto as Exhibit D-7.
The Certificate Administrator may not consent to, or otherwise permit, any such release without obtaining the Retaining Sponsor’s
countersigned request for consent. The Certificate Administrator shall be indemnified and held harmless for any release in connection
with the preceding, in accordance with the terms set forth in Section 8.03. The Certificate Administrator shall have no
further obligations with respect to the safekeeping of such released certificates.

 

Section
5.02     Form and Registration. No transfer of any Non-Registered Certificate shall be made unless
that transfer is made pursuant to an effective registration statement under the Securities Act, and effective registration or
qualification under applicable state securities laws, or is made in a transaction which does not require such registration or
qualification. If a transfer (other than one by the Depositor to an Affiliate thereof or by the Initial Purchasers to RREF III
- D AIV RR, LLC) is to be made in reliance upon an exemption from the Securities Act, and under the applicable state securities
laws, then either:

 

(a)       Each
Class of the Non-Registered Certificates (other than the HRR Certificates and Class R Certificates) sold to institutions that
are non-United States Securities Persons in Offshore Transactions in reliance on Regulation S under the Act shall initially be
represented by a temporary book-entry certificate in definitive, fully registered form without interest coupons, substantially
in the applicable form set forth as an exhibit hereto (each a “Temporary Regulation S Book-Entry Certificate”),
which shall be deposited on the Closing Date on behalf of the purchasers of the Non-Registered Certificates represented thereby
with the Certificate Registrar, at its principal trust office, as custodian, for the Depository, and registered in the name of
the Depository or the nominee of the Depository for the account of designated agents holding on behalf of Euroclear and/or Clearstream.
Prior to the expiration of the 40-day period commencing on the later of the commencement of the offering and the Closing Date
(the “Restricted Period”), beneficial interests in each Temporary Regulation S Book-Entry Certificate

 

    -362-

     

    

 

may
be held only through Euroclear or Clearstream. After the expiration of the Restricted Period, a beneficial interest in a Temporary
Regulation S Book-Entry Certificate may be exchanged for an interest in the related Regulation S Book-Entry Certificate in the
applicable form set forth as an exhibit hereto in accordance with the procedures set forth in Section 5.03(f). During the
Restricted Period, distributions due in respect of a beneficial interest in a Temporary Regulation S Book-Entry Certificate shall
only be made upon delivery to the Certificate Registrar by Euroclear or Clearstream, as applicable, of a Non-U.S. Beneficial Ownership
Certification. After the expiration of the Restricted Period, distributions due in respect of any beneficial interests in a Temporary
Regulation S Book-Entry Certificate shall not be made to the holders of such beneficial interests unless exchange for a beneficial
interest in the Regulation S Book-Entry Certificate of the same Class is improperly withheld or refused. The aggregate Certificate
Balance of a Temporary Regulation S Book-Entry Certificate or a Regulation S Book-Entry Certificate may from time to time be increased
or decreased by adjustments made on the records of the Certificate Registrar, as custodian for the Depository, as hereinafter
provided.

 

On
the Closing Date, the Certificate Administrator shall execute, the Authenticating Agent shall authenticate, and the Certificate
Administrator shall deliver to the Certificate Registrar the Regulation S Book-Entry Certificates, which shall be held by the
Certificate Registrar for purposes of effecting the exchanges contemplated by the preceding paragraph. Wells Fargo Bank is hereby
appointed the initial Authenticating Agent with the power to act, on the Trustee’s behalf, in the authentication and delivery
of the Certificates in connection with transfers and exchanges as herein provided. If Wells Fargo Bank, National Association is
removed as Certificate Administrator, then Wells Fargo Bank, National Association shall be terminated as Authenticating Agent.
If the Authenticating Agent is terminated, the Trustee shall appoint a successor authenticating agent, which may be the Trustee
or an Affiliate thereof.

 

(b)       Certificates
of each Class of Non-Registered Certificates (other than the HRR Certificates and other than the VRR Interest following the conversion
described in Section 5.03(i) hereof during the Transfer Restriction Period) offered and sold to Qualified Institutional
Buyers in reliance on Rule 144A shall be represented by Rule 144A Book-Entry Certificates, which shall be deposited with the Certificate
Registrar or an agent of the Certificate Registrar, as custodian for the Depository, and registered in the name of the Depository
or a nominee of the Depository. The aggregate Certificate Balance of a Rule 144A Book-Entry Certificate may from time to time
be increased or decreased by adjustments made on the records of the Certificate Registrar, as custodian for the Depository, as
hereinafter provided.

 

(c)       Certificates
of each Class of Non-Registered Certificates that are initially offered and sold to investors that are
Institutional Accredited Investors that are not Qualified Institutional Buyers, the HRR Certificates and the Class R
Certificates (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 by the Certificate Registrar in
the name of such investors or their nominees who have provided the Certificate Registrar with an Investment Representation
Letter substantially in the form of Exhibit C, and the Certificate Registrar shall deliver the certificates for such Non-Book
Entry Certificates to the respective beneficial owners or owners. For the avoidance of doubt, the Class V, Class R and Class
Z Certificates and the HRR Certificates shall only be in the form of Definitive Certificates, and the Certificates evidencing
the VRR Interest shall be converted following their initial issuance to the form of Definitive

 

    -363-

     

    

 

Certificates
pursuant to Section 5.02(j) and shall thereafter at all times during the Transfer Restriction Period be held in such form.

 

(d)       Owners
of beneficial interests in Book-Entry Certificates of any Class shall not be entitled to receive physical delivery of certificated
Certificates unless: (i) the Depository advises the Certificate Registrar in writing that the Depository is no longer willing
or able to discharge properly its responsibilities as depository with respect to the Book-Entry Certificates of such Class or
ceases to be a Clearing Agency, and the Certificate Registrar and the Depository are unable to locate a qualified successor within
ninety (90) days of such notice or (ii) the Trustee has instituted or has been directed to institute any judicial proceeding to
enforce the rights of the Holders of such Class and the Trustee has been advised by counsel that in connection with such proceeding
it is necessary or appropriate for the Certificate Registrar to obtain possession of the Certificates of such Class; provided,
however, that under no circumstances will certificated Non-Registered Certificates be issued to beneficial owners of a
Temporary Regulation S Book-Entry Certificate. Upon notice of the occurrence of any of the events described in clause (i)
or (ii) above with respect to any Certificates of a Class that are in the form of Book-Entry Certificates and upon surrender
by the Depository of any Book-Entry Certificate of such Class and receipt from the Depository of instructions for re-registration,
the Certificate Registrar shall issue Certificates of such Class in the form of Definitive Certificates (bearing, in the case
of a Definitive Certificate issued for a Rule 144A Book-Entry Certificate, the same legends regarding transfer restrictions borne
by such Book-Entry Certificate), and thereafter the Certificate Registrar shall recognize the Holders of such Definitive Certificates
as Certificateholders under this Agreement. Unless and until Definitive Certificates are issued in respect of a Class of Book-Entry
Certificates, beneficial ownership interests in such Class of Certificates will be maintained and transferred on the book entry
records of the Depository and Depository Participants, and all references to actions by Holders of such Class of Certificates
will refer to action taken by the Depository upon instructions received from the related registered Holders of Certificates through
the Depository Participants in accordance with the Depository’s procedures and, except as otherwise set forth herein, all
references herein to payments, notices, reports and statements to Holders of such Class of Certificates will refer to payments,
notices, reports and statements to the Depository or its nominee as the registered Holder thereof, for distribution to the related
registered Holders of Certificates through the Depository Participants in accordance with the Depository’s procedures.

 

(e)       Other
than as provided for in Section 5.03(i), any VRR Interest shall only be held as a Definitive Certificate in a Retained
Interest Safekeeping Account by the Certificate Administrator (the Retaining Party’s interest shall be tracked in the form
of an entry in the Certificate Administrator’s trust accounting system under such Retained Interest Safekeeping Account),
for the benefit of the Holder of the related Certificate. The Certificate Administrator shall hold each Certificate evidencing
the VRR Interest in safekeeping and shall release the same only upon receipt of written direction from a holder of the VRR Interest,
the Depositor and the Retaining Sponsor, and in accordance with any authentication procedures as may be utilized by the Certificate
Administrator and in accordance with this Agreement. There shall be, and hereby is, established by the Certificate Administrator
an account which will be designated a “Retained Interest Safekeeping Account” and into which the VRR Interest shall
be held and which shall be governed by and subject to this Agreement. In addition, on and after the date hereof, the Certificate
Administrator may establish any number of subaccounts to the Retained Interest

 

    -364-

     

    

 

Safekeeping
Account for the Retaining Party. The VRR Interest to be delivered in physical form to the Certificate Administrator shall be delivered
as set forth herein. No amounts distributable to the VRR Interest shall be remitted to the related Retained Interest Safekeeping
Account, but shall be remitted directly to the Retaining Party in accordance with written instructions provided separately by
the Retaining Party to the Certificate Administrator; provided, however, that with respect to the first Distribution Date, if
the VRR Interest is not exchanged into a Definitive Certificate by the first Record Date pursuant to Section 5.03(i), then
the Certificate Administrator shall be authorized to disburse the amounts remitted by DTC into the Retained Interest Safekeeping
Account on the first Distribution Date to the Retaining Party as distributions to the Retaining Party and such amounts shall be
disbursed pursuant to the written instructions provided by the Retaining Party to the Certificate Administrator. Under no circumstances
by virtue of safekeeping the VRR Interest shall the Certificate Administrator be obligated to bring legal action or institute
proceedings against any person on behalf of the Retaining Party. During the Transfer Restriction Period and for such longer time
as the Retaining Party may request, the Certificate Administrator shall hold the Definitive Certificate representing the VRR Interest
at the below location, or any other location; provided the Certificate Administrator has given notice to the Retaining
Party of such new location:

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 Book-Entry Certificate equal to the beneficial interest in the
Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate to be exchanged, such instructions to contain

    -367-

     

    

 

Exhibit
K hereto given by the holder of such beneficial interest and stating that the Person transferring such interest in the Temporary
Regulation S Book-Entry Certificate reasonably believes that the Person acquiring such interest in the Rule 144A Book-Entry Certificate
is a Qualified Institutional Buyer or (ii) after the Restricted Period, an Investment Representation Letter in the form of Exhibit

of the Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate and to increase, or cause to be increased,
the Certificate Balance of the Rule 144A Book-Entry Certificate by the aggregate Certificate Balance of the beneficial interest

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 Book-Entry Certificate equal to the reduction
in the Certificate Balance of the Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry 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 Book-Entry Certificate or Regulation S Book-Entry Certificate that is being transferred.

 

(f)       Temporary
Regulation S Book-Entry Certificate to Regulation S Book-Entry Certificate. Interests in a Temporary Regulation S Book-Entry
Certificate as to which the Certificate Registrar has received from Euroclear or Clearstream, as the case may be, a certificate
(a “Non-U.S. Beneficial Ownership Certification”) to the effect that Euroclear or Clearstream, as applicable,
has received a certificate substantially in the form of Exhibit L hereto from the holder of a beneficial interest in such
Temporary Regulation S Book-Entry Certificate, shall be exchanged after the Restricted Period, for interests in the Regulation
S Book-Entry Certificate of the same Class. The Certificate Registrar shall effect such exchange by delivering to the Depository
for credit to the respective accounts of such holders, a duly executed and authenticated Regulation S Book-Entry Certificate,
representing the aggregate Certificate Balance of interests in the Temporary Regulation S Book-Entry Certificate initially exchanged
for interests in the Regulation S Book-Entry Certificate. The delivery to the Certificate Registrar by Euroclear or Clearstream
of the certificate or certificates referred to above may be relied upon by the Depositor and the Certificate Registrar as conclusive
evidence that the certificate or certificates referred to therein has or have been delivered to Euroclear or Clearstream pursuant
to the terms of this Agreement and the Temporary Regulation S Book-Entry Certificate. Upon any exchange of interests in the Temporary
Regulation S Book-Entry Certificate for interests in the Regulation S Book-Entry Certificate, the Certificate Registrar shall
endorse the Temporary Regulation S Book-Entry Certificate to reflect the reduction in the Certificate Balance represented thereby
by the amount so exchanged and shall endorse the Regulation S Book-Entry Certificate to reflect the corresponding increase in
the amount represented thereby. Until so exchanged in full and except as provided therein, the Temporary Regulation S Book-Entry
Certificate, and the Certificates evidenced thereby, shall in all respects be entitled to the same benefits under this Agreement
as the Regulation S Book-Entry Certificate and Rule 144A Book-Entry Certificate authenticated and delivered hereunder.

 

    -368-

     

    

 

(g)       Non-Book
Entry Certificate to Book-Entry Certificate. If a holder of a Non-Book Entry Certificate (other than (a) a Class R Certificate,
(b) a Class Z Certificate or (c) an HRR Certificate or any Certificate evidencing the VRR Interest during the Transfer Restriction
Period) wishes at any time to exchange its interest in such Non-Book Entry Certificate for an interest in a Book-Entry Certificate
of the same Class, or to transfer all or part of such Non-Book Entry Certificate to a Person who is entitled to take delivery
thereof in the form of an interest in a Book-Entry Certificate, such holder may, subject to the rules and procedures of Euroclear
or Clearstream, if applicable, and the Depository, cause the exchange of all or part of such Non-Book Entry Certificate for an
equivalent beneficial interest in the appropriate Book-Entry Certificate of the same Class. Upon receipt by the Certificate Registrar,
as registrar, at its office designated in Section 5.07, of (1) such Non-Book Entry Certificate, duly endorsed as provided
herein, (2) instructions from such holder directing the Certificate Registrar, as registrar, to credit, or cause to be credited,
a beneficial interest in the applicable Book-Entry Certificate equal to the portion of the Certificate Balance of the Non-Book
Entry Certificate to be exchanged, such instructions to contain information regarding the participant account with the Depository
to be credited with such increase and (3) a certificate in the form of Exhibit M hereto (in the event that the applicable
Book-Entry Certificate is the Temporary Regulation S Book-Entry Certificate), in the form of Exhibit N hereto (in the event
that the applicable Book-Entry Certificate is the Regulation S Book-Entry Certificate) or in the form of Exhibit O hereto
(in the event that the applicable Book-Entry Certificate is the Rule 144A Book-Entry Certificate), then the Certificate Registrar,
as registrar, shall cancel, or cause to be canceled, all or part of such Non-Book Entry Certificate, shall, if applicable, execute,
authenticate and deliver to the transferor a new Non-Book Entry Certificate equal to the aggregate Certificate Balance of the
portion retained by such transferor and shall instruct the Depository to increase, or cause to be increased, such Book-Entry Certificate
by the aggregate Certificate Balance of the portion of the Non-Book Entry Certificate to be exchanged and to credit, or cause
to be credited, to the account of the Person specified in such instructions a beneficial interest in the applicable Book-Entry
Certificate equal to the Certificate Balance of the portion of the Non-Book Entry Certificate so canceled. Upon the written direction
of the Depositor (which may be by email to cts.cmbs.bond.admin@wellsfargo.com) or its Affiliate, the Certificate Registrar shall
execute any instrument as may be reasonably required by the Depository to effect such exchange.

 

(h)       Non-Book
Entry Certificates on Initial Issuance Only. Subject to the issuance of Definitive Certificates, if and when permitted by
Section 5.02(c) and Section 5.02(d), and subject to the issuance and transfer of the VRR Interest in accordance
with Section 5.03(i), no Non-Book Entry Certificate shall be issued to a transferee of an interest in any Rule 144A Book-Entry
Certificate, Temporary Regulation S Book-Entry Certificate or Regulation S Book-Entry Certificate or to a transferee of a Non-Book
Entry Certificate (or any portion thereof).

 

(i)       Transfers
of VRR Interest. At all times, if a Transfer of all or a portion of the VRR Interest is to be made, then the Certificate Registrar
shall refuse to register such transfer unless it receives (and, upon receipt, may conclusively rely upon) (i) a certification
from such Certificateholder’s prospective Transferee substantially in the form attached hereto as Exhibit D-3, which
such certification must be countersigned by the Retaining Sponsor and Depositor with a medallion stamp guarantee of the Retaining
Sponsor and (ii) a certification from the Certificateholder desiring to effect such transfer substantially in the form attached
hereto as Exhibit D-4, which such certification must be countersigned by the Retaining Sponsor

 

    -369-

     

    

 

and
the Depositor with a medallion stamp guarantee of the Retaining Sponsor. Upon receipt of the foregoing certifications, the
Certificate Registrar shall, subject to Section 5.02(e) and Section 5.03(a), reflect all or any such portion of
the VRR Interest in the name of the prospective Transferee. For the avoidance of doubt, other than at initial issuance, in no
event shall an VRR Interest be held as a Book-Entry Certificate during the Transfer Restriction Period; provided that,
each Certificate representing the VRR Interest shall on the Closing Date be issued in book-entry form and shall initially be
held as a Book-Entry Certificate; however, upon initial issuance on the Closing Date, the Certificate Administrator is hereby
instructed by the Depositor to exchange the Book-Entry Certificate(s) representing the VRR Interest for a Definitive
Certificate as soon as practicable after the Closing Date but no later than two (2) Business Days after the Closing Date and
shall hold each Definitive Certificate evidencing the VRR Interest in safekeeping pursuant to Section 5.02(e). Any
attempted or purported transfer in violation of this Section 5.03(i) shall be null and void ab initio and shall
vest no rights in any purported transferee and shall not relieve the transferor of any obligations with respect to the
applicable Certificates.

 

(j)        Other
Exchanges. In the event that a Book-Entry Certificate is exchanged for a Definitive Certificate, such Certificates may be
exchanged only in accordance with such procedures as are substantially consistent with the provisions of subsections (c)
through (f) above (including the certification requirements intended to ensure that such transfers comply with Rule 144A
or Regulation S under the Act, at the case may be) and such other procedures as may from time to time be adopted by the Certificate
Registrar.

 

(k)       Restricted
Period. Prior to the termination of the Restricted Period with respect to the issuance of the Certificates, transfers of interests
in the Temporary Regulation S Book-Entry Certificate to U.S. persons (as defined in Regulation S) shall be limited to transfers
made pursuant to the provisions of subsection (e) above.

 

(l)        If
Non-Registered Certificates are issued upon the transfer, exchange or replacement of Certificates bearing a restrictive legend
relating to compliance with the Act, or if a request is made to remove such legend on Certificates, the Non-Registered Certificates
so issued shall bear the restrictive legend, or such legend shall not be removed, as the case may be, unless there is delivered
to the Certificate Registrar such satisfactory evidence, which may include an Opinion of Counsel that neither such legend nor
the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule
144A or Regulation S under the Act. Upon provision of such satisfactory evidence, the Certificate Registrar shall authenticate
and deliver Certificates that do not bear such legend.

 

(m)      All
Certificates surrendered for registration of transfer and exchange shall be canceled and subsequently destroyed by the Certificate
Registrar in accordance with the Certificate Registrar’s customary procedures.

 

(n)       With
respect to the ERISA Restricted Certificates, no sale, transfer, pledge or other disposition (other than any initial transfer
to the Initial Purchasers or with respect to the VRR Interest, NREC acting as a Retaining Party) of any such Certificate shall
be made unless the Trustee and Certificate Administrator shall have received either (i) a representation letter from the proposed
purchaser or transferee of such Certificate substantially in the form of Exhibit F-1 attached hereto, to the effect that
such proposed purchaser or transferee is not and

 

    -370-

     

    

 

will
not become (A) an employee benefit plan subject to the fiduciary responsibility provisions of ERISA or a plan subject to
Section 4975 of the Code, or a governmental plan (as defined in Section 3(32) of ERISA), a church plan (as defined in Section
3(33) of ERISA) for which no election has been made under Section 410(d) of the Code or any other plan subject to any
federal, state or local law (“Similar Law”) which is, to a material extent, similar to the foregoing
provisions of ERISA or the Code (each, a “Plan”) or (B) a person acting on behalf of or using the assets
of any such Plan (including an entity whose underlying assets include Plan assets by reason of investment in the entity by
such Plan and the application of Department of Labor Regulation § 2510.3-101, as modified by Section 3(42) of ERISA),
other than an insurance company using the assets of its general account under circumstances whereby the purchase and holding
of such Certificates by such insurance company would be exempt from the prohibited transaction provisions of ERISA and the
Code under Sections I and III of Prohibited Transaction Class Exemption 95-60 (or, in the case of a Plan subject to Similar
Law, would not result in a non-exempt violation of Similar Law) or (ii) if such Certificate which may be held only by a
person not described in clauses (A) or (B) above, is presented for registration in the name of a purchaser or
transferee that is any of the foregoing, an Opinion of Counsel in form and substance satisfactory to the Trustee and
Certificate Administrator and the Depositor to the effect that the acquisition and holding of such Certificate by such
purchaser or transferee will not constitute or result in a non-exempt “prohibited transaction” within the meaning
of ERISA, Section 4975 of the Code or a non-exempt violation of any Similar Law, and will not subject the Trustee, the
Certificate Administrator, the Master Servicer, the Special Servicer, the Initial Purchasers, the Underwriters, the
Operating Advisor or the Depositor to any obligation or liability (including obligations or liabilities under ERISA, Section
4975 of the Code or any such Similar Law) in addition to those set forth in the Agreement. The Trustee and Certificate
Administrator shall not register the sale, transfer, pledge or other disposition of any ERISA Restricted Certificate unless
the Trustee and Certificate Administrator have received either the representation letter described in clause (i) above
or the Opinion of Counsel described in clause (ii) above. The costs of any of the foregoing representation letters or
Opinions of Counsel shall not be borne by any of the Depositor, the Master Servicer, the Special Servicer, the Trustee, the
Certificate Administrator, the Initial Purchasers, the Underwriters, the Operating Advisor, the Asset Representations
Reviewer or the Trust. Each Certificate Owner of an ERISA Restricted Certificate shall be deemed to represent that it is not
and will not become a Person specified in clauses (i)(A) or (i)(B) above. Any transfer, sale, pledge or other
disposition of any ERISA Restricted Certificates that would constitute or result in a prohibited transaction under ERISA,
Section 4975 of the Code or any Similar Law, or would otherwise violate the provisions of this Section 5.03(n) shall
be deemed absolutely null and void ab initio, to the extent permitted under applicable law.

 

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

 

(1)
none of the Depositor, the Underwriters, the Initial Purchasers, the Trustee, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer or any of their respective affiliated entities (the “Transaction Parties”),

or (ii) a participant or beneficiary of the ERISA Plan investing in the Certificates in such capacity);

 

(2)

(4)

representations shall be deemed to be no longer in effect.

 

(o)       No
Class V1-Z, Class V2-Z, Class R or Class Z Certificate may be purchased by or transferred to any prospective purchaser or transferee

prospective
transferee of a Class V1-Z, Class V2-Z, Class R or Class Z Certificate shall deliver to the transferor and the Certificate Administrator
a representation letter, substantially in the form of Exhibit F-2, stating that the prospective transferee is not a Plan

restrictions shall be null and void ab initio and shall vest no rights in any purported transferee and shall not relieve
the transferor of any obligations with respect to the applicable Certificates.

 

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

 

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

 

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

 

    -373-

     

    

 

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

 

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

 

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

 

(q)       At
all times, if a transfer of the HRR Certificates is to be made, then the Certificate Registrar shall refuse to register such transfer
unless it receives (and, upon receipt, may conclusively rely upon) (i) a certification from such Certificateholder’s prospective
transferee substantially in the form attached hereto as Exhibit D-5, which such certification must be countersigned by
the Retaining Sponsor (which shall not be unreasonably withheld, delayed or conditioned) with a medallion stamp guarantee of the
Retaining Sponsor and (ii) a certification from the Certificateholder desiring to effect such transfer substantially in the form
attached hereto as Exhibit D-6, which such certification must be countersigned by the Retaining Sponsor (which shall not
be unreasonably withheld, delayed or conditioned) with a medallion stamp guarantee of the Retaining Sponsor. Upon receipt of the
foregoing certifications, the Certificate Registrar shall, subject to Section 5.01(c) and Section 5.03, reflect
the HRR Certificates in the name of the prospective transferee. For the avoidance of doubt, in no event shall the HRR Certificates
be held as a Global Certificate during the Transfer Restriction Period.

believes are applicable under the Code. The consent of Certificateholders or payees shall not be required for such withholding,
and the Certificateholders shall be required to provide the Certificate Administrator with such forms and other such information

Registrar, or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate
and (b) there is delivered to the Certificate Registrar such security or indemnity as may be required by it to save it harmless,
then, in the absence of actual notice to the Certificate Registrar that such Certificate has been acquired by a bona fide purchaser,
the Certificate Registrar shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed,
lost or stolen Certificate, a new Certificate of like tenor and interest in the Trust. In connection with the issuance of any
new Certificate under this Section 5.04, the Certificate Registrar may require the payment of a sum sufficient to cover
any expenses (including the fees and expenses of the Certificate Registrar) connected therewith. Any replacement Certificate issued
pursuant to this Section 5.04 shall constitute complete and indefeasible evidence of ownership in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

with other Certificateholders with respect to its rights under this Agreement or under the Certificates and

ten (10) Business Days after the receipt of such request, afford such Certificateholder (at such Certificateholder’s sole
cost and expense) access during normal business hours to a current list of the Certificateholders as of the most recent Record
Date as they appear in the Certificate Register. Every Certificateholder, by receiving and holding a Certificate, agrees that
the Certificate Registrar shall not be held accountable by reason of the disclosure of any such information as to the list of
the Certificateholders hereunder, regardless of the source from which information was derived. The Master Servicer, the Special
Servicer, the Trustee, the Certificate Administrator, the Operating Advisor and the Depositor shall be entitled to a list of the

use to contact the requesting Certificateholder or Certificate Owner.

 

In
verifying the identity of any Certificateholder or Certificate Owner in connection with any request to communicate, (i) if the
Certificateholder or Certificate Owner is the holder of record with respect to any Certificate, the Certificate Administrator
shall not require any further verification or (ii) if the Certificateholder or Certificate Owner is not the holder of record with
respect to any Certificate, the Certificate Administrator shall require no more than (x) a written certification from such Certificateholder
or Certificate Owner that it is the beneficial owner of a Certificate, (y) the name of the transaction, 2017-CX9, and (z) one
of the following documents confirming ownership of such Certificate: a trade confirmation, an account statement, a letter from
a broker-dealer or another document acceptable to the Certificate Administrator that is similar to any of the foregoing documents).
The Certificate Administrator shall not have any obligation to verify the information provided by any Certificateholder or Certificate
Owner in any request to communicate and may rely on such information conclusively. Additionally, any expenses the Certificate
Administrator incurs in connection with any request to communicate will be paid by the Trust.

with Section 5.09(d)) on the Closing Date with, other than in the case of the Class Z Certificates, the respective aggregate
initial Certificate Balance or Notional Amount, as applicable, set forth for such Class in the Preliminary Statement.

 

(c)       Following
the Closing Date and subject to the conditions set forth in Section 5.09(d), if a Certificateholder holds a uniform Tranche

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

 

(d)       An
exchange of an Exchangeable Group may only occur if the Certificates being surrendered or received in such exchange have denominations
no smaller than the minimum Denominations set forth in Section 5.01. There shall be no limitation on the number of exchanges
of Exchangeable Groups of Certificates authorized pursuant to this Section 5.09. In addition, the Depositor shall have
the right to make or cause exchanges on the Closing Date and shall deliver instructions substantially in the form of Exhibit
TT to the Certificate Administrator along with the original Certificate exchanged (unless such exchanged Certificate was deemed
issued).

 

(e)       For
any exchange other than any exchange effectuated on the Closing Date by the Depositor pursuant to Section 5.09(d), at the
request of the Holder of a uniform Tranche Percentage Interest of an Exchangeable Group of Certificates, and upon the surrender
of the Certificates evidencing such Tranche Percentage, the Certificate Administrator, on behalf of the Trustee, shall deliver
(by the means set forth in the penultimate sentence of Section 5.09(g)) the corresponding Exchangeable Group of Certificates
to which such Certificateholder is entitled as set forth in Section 5.09(c).

 

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

 

    -379-

     

    

 

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

 

(g)       For
all exchanges other than any exchange effectuated by the Depositor pursuant to Section 5.09(d), in order to effect an exchange
of an Exchangeable Group of Certificates, the Certificateholder shall notify the Certificate Administrator in writing or by e-mail
at cts.cmbs.bond.admin@wellsfargo.com (with a subject line referencing “CSAIL 2017-CX9” and setting forth the proposed
Exchange Date) no later than three (3) Business Days before the proposed exchange date (the “Exchange Date”).
The Exchange Date may be any Business Day other than the first or last Business Day of the month. An exchange notice must (i)
be set forth on the applicable Certificateholder’s letterhead, (ii) carry a medallion stamp guarantee and (iii) set forth
the following information: the CUSIP Number of each Certificate to be exchanged and each Certificate to be received; the original
and outstanding Certificate Balance or Notional Amount, as applicable, of the Certificates to be exchanged and the original and
outstanding Certificate Balance or Notional Amount, as applicable, of the Certificates to be received; the Certificateholder’s
Depository participant number, if applicable; and the proposed Exchange Date. The Certificateholder and the Certificate Registrar
shall utilize the “deposit and withdrawal system” at the Depository to effect the exchange of the applicable Certificates
that are Global Certificates. A notice shall become irrevocable on the second (2nd) Business Day before the proposed Exchange
Date. Global Certificates shall be exchangeable on the books of the Depository for the corresponding Global Certificates on and
after the Closing Date, by notice to the Certificate Administrator substantially in the form of Exhibit TT.

 

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

 

Section
5.10      Voting Procedures. With respect to any matters submitted to Certificateholders for a
vote, the Certificate Administrator shall administer such vote through the Depository with respect to Book-Entry Certificates
and directly with registered Holders by mail with respect to Definitive Certificates. In each case, such vote shall be administered
in accordance with the following procedures, unless different procedures are otherwise described herein with respect to a specific
vote:

 

(a)       Any
matter submitted to Certificateholders for a vote shall be announced in a notice prepared by the Certificate Administrator. Such
notice shall include the record date

 

    -380-

     

    

 

determined
by the Certificate Administrator for purposes of the vote and a voting deadline which shall be no less than thirty (30) days and
no later than sixty (60) days after the date such notice is distributed. The notice and related ballot shall be sent to Holders
of Book-Entry Certificates through the Depository and by mail to the registered Holders of Definitive Certificates. In addition,
the notice and related ballot shall be posted to the Certificate Administrator’s Website. Notices delivered in this manner
shall be considered delivered to all Holders regardless of whether any Holder actually receives the notice and ballot.

 

(b)       In
connection with any vote administered pursuant to this Agreement, voting Holders shall be required to certify their holdings in
the manner set forth on the ballot, unless a specific manner is otherwise provided herein. Holders may only vote in accordance
with their Voting Rights. Voting Rights with respect to any outstanding Class of Certificates shall be calculated by the Certificate
Administrator in accordance with the definition of Voting Rights as of the record date for the vote. Only Classes with an outstanding
Certificate Balance or Notional Amount greater than zero as of the record date of the vote shall be permitted to vote. Once a
Holder has cast its vote, the vote may be changed or retracted on or before the vote deadline. Any changes or retractions shall
be communicated by the Certificateholder to the Certificate Administrator in writing on a ballot. After the vote deadline has
passed, votes may not be changed or retracted by any Holder unless the Holder wishing to change or retract its vote holds a sufficient
portion of the Voting Rights such that the Holder, by its vote alone, could approve or deny the proposition subject to a vote
without taking into consideration the votes cast by any other Holder. Transferees or purchasers of any Class of Certificates are
subject to and shall be bound by all votes of Holders initiated or conducted prior to its acquisition of such Certificate.

 

(c)       The
Certificate Administrator may take up to fifteen (15) Business Days to tabulate the results of any vote. The Certificate Administrator
shall use its reasonable efforts to resolve any illegible or incomplete ballots received prior to the voting deadline. Illegible
or incomplete ballots that are received on the voting deadline or that cannot be resolved by the voting deadline shall not be
counted. Promptly after the votes are tabulated, the Certificate Administrator shall prepare a notice announcing the results of
the vote. Such notice shall include the percentage of Voting Rights in favor of the proposition, the percentage against the proposition
and the percentage abstaining. In addition, the notice will announce whether the proposition has been adopted by Certificateholders.
The notice shall be distributed in accordance with the methods described in Section 5.10(a) above. The Certificate Administrator
shall also include such notice on the Form 10-D prepared in connection with the distribution period that corresponds with the
date such notice is distributed. All vote tabulations shall be final and the Certificate Administrator shall not, absent manifest
error, re-tabulate the votes or conduct a new vote for the same proposition.

 

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

 

(e)       If
any party to this Agreement believes a vote of Certificateholders is needed for some matter related to the administration of the
Trust that is not specifically

 

    -381-

     

    

 

contemplated
herein, such party may request the Certificate Administrator to conduct a vote and the Certificate Administrator will conduct
the requested vote in accordance with these procedures. Unless specifically provided herein, all such votes require a majority
of Certificateholders to carry a proposition.

(b)            
The Depositor, the Master Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer each may
be merged or consolidated with or into any Person, or transfer all or substantially all of its assets (which may be limited to
all or substantially all of its assets related to commercial mortgage loan servicing or commercial mortgage surveillance, as the
case may be) to any Person, in which case any Person resulting from any merger or consolidation to which the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer shall be a party, or any Person succeeding
to the business of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations
Reviewer, shall be the successor of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, or the Asset
Representations Reviewer (such Person, in the case of the Master Servicer or the Special Servicer, in each of the foregoing cases,
the “Surviving Entity”), as the case may be, hereunder, without the execution or filing of any paper (other
than an assumption agreement wherein the successor shall agree to perform the obligations of and serve as the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, or the Asset Representations Reviewer, as the case may be, in accordance
with the terms of this Agreement) or any further act on the part of any of the parties hereto, anything herein to the contrary

Confirmation is

 

    -388-

     

    

 

received
from each Rating Agency with respect to the Classes of Certificates and, with respect to any class of Serviced Companion Loan
Securities, a confirmation is received from each applicable rating agency that such action will not result in the downgrade, withdrawal
or qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates as described
in Section 3.25); provided, further, that if the Master Servicer, the Special Servicer, the Operating
Advisor or the Asset Representations Reviewer enters into a merger and the Master Servicer, the Special Servicer, the Operating
Advisor or the Asset Representations Reviewer, as applicable, is the Surviving Entity under applicable law, the Master Servicer,
the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, as applicable, shall not, as a result of the
merger, be required to provide a Rating Agency Confirmation with respect to ratings of the Classes of Certificates or, with respect
to any class of Serviced Companion Loan Securities, a confirmation of the rating agencies that such action will not result in
the downgrade, withdrawal or qualification of its then-current ratings; provided, further, that for so long as the
Trust, and, with respect to any Companion Loan included as part of the trust in a related Other Securitization, is subject to
the reporting requirements of the Exchange Act, if the Master Servicer, the Special Servicer, the Operating Advisor or the Asset
Representations Reviewer notifies the Depositor in writing (a “Merger Notice”) of any such merger, consolidation,
conversion or other change in form, and the Depositor or the depositor in such Other Securitization, as the case may be, notifies
the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations Reviewer, as applicable, in writing
that the Depositor or the depositor in such Other Securitization, as the case may be, has discovered that such successor entity
has not complied with its Exchange Act reporting obligations under any other commercial mortgage loan securitization (and specifically
identifying the instance of noncompliance), then it shall be an additional condition to such succession that the Depositor or
the depositor in such Other Securitization, as the case may be, shall have consented (which consent shall not be unreasonably
withheld or delayed) to such successor entity. Notwithstanding the foregoing, no Master Servicer, Special Servicer or Operating
Advisor may remain the Master Servicer, the Special Servicer or Operating Advisor, as applicable, under this Agreement after (x) being
merged or consolidated with or into any Person that is a Prohibited Party, or (y) transferring all or substantially all of its
assets to any Person if such Person is a Prohibited Party, except to the extent (i) the Master Servicer, the Special Servicer
or Operating Advisor, as applicable, is the Surviving Entity of such merger, consolidation or transfer and has been and continues
to be in compliance with its Regulation AB reporting obligations hereunder or (ii) the Depositor consents to such merger,
consolidation or transfer, which consent shall not be unreasonably withheld. If, within sixty (60) days following the date of
delivery of the Merger Notice to the Depositor or the depositor in such Other Securitization, as the case may be, the Depositor
or depositor in such Other Securitization, as the case may be, shall have failed to notify the Master Servicer or the Special
Servicer, as applicable, in writing of the Depositor’s determination, or depositor’s determination, in the case of
an Other Securitization, to grant or withhold such consent, such failure shall be deemed to constitute a grant of such consent.
If the conditions to the provisions in the second preceding sentence are not met, the Trustee may terminate, and if the conditions
set forth in the third proviso of the third preceding sentence are not met the Trustee shall terminate, the applicable Surviving
Entity’s servicing of the Mortgage Loans pursuant hereto, such termination to be effected in the manner set forth in Section 7.01.

that (i) this provision shall not protect the Depositor, the Master Servicer (including in its capacity as Companion Paying
Agent), the Special Servicer, the Operating Advisor, the Asset Representations Reviewer or any such Person against any breach
of warranties or representations made by it herein or any liability which would otherwise be imposed by reason of willful misconduct,

such party’s obligations and duties hereunder. The Depositor, the Master Servicer (including in its capacity as Companion
Paying Agent), the Special Servicer, the Operating Advisor, the Asset Representations Reviewer and any partner, director, officer,
shareholder, member, manager, employee or agent of the Depositor, the Master Servicer (including in its capacity as Companion

Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Asset Representations
Reviewer and the Operating Advisor and any partner, director, officer, shareholder, member, manager, employee or agent of any
of the foregoing shall be indemnified and held harmless by the Trust against any and all claims, losses, penalties, fines, forfeitures,
reasonable legal fees and related costs, judgments, and any other costs, liabilities, fees and expenses incurred in connection
with, or related to, this Agreement, the Mortgage Loans, the Companion Loans or the Certificates, other than any loss, liability

with any breach of a representation or warranty made by it herein; (iii) incurred by reason of bad faith, willful misconduct
or negligence in the performance of its obligations or duties hereunder, or by reason of negligent disregard of such obligations

employees and agents, incurred in connection with any violation by any of them of any state or federal securities law. In addition,
absent actual fraud (as determined by a final non-appealable court order), neither the Trustee nor the Certificate Administrator
(including in its capacity as Custodian) shall be liable for special, punitive, indirect or consequential loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Trustee or the Certificate Administrator has been advised
of the likelihood of such loss or damage and regardless of the form of action. Each of the Master Servicer (including in its capacity
as Companion Paying Agent), the Special Servicer, the Asset Representations Reviewer and the Operating Advisor conclusively may
rely on, and shall be protected in acting or refraining from acting upon, any resolution, officer’s certificate, certificate
of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, financial statement,
agreement, appraisal, bond or other document (in electronic or paper format) as contemplated by and in accordance with this Agreement
and reasonably believed or in good faith believed by the Master Servicer (including in its capacity as Companion Paying Agent),

(b)             None of the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Operating
Advisor and the Asset Representations Reviewer shall be under any obligation to appear in, prosecute or defend any legal or administrative
action (whether in equity or at law), proceeding, hearing or examination that is not incidental to its respective duties under
this Agreement or which in its opinion may involve it in any expense or liability not recoverable from the Trust; provided,
however, that each of the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor or the Asset Representations
Reviewer may in its discretion undertake any such action, proceeding, hearing or examination that it may deem necessary or desirable
in respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders (and,
in the case of any Serviced Whole Loan, the rights of the Certificateholders and the holders of a Serviced Companion Loan (as
a collective whole) taking into account the subordinate or pari passu nature of such Serviced Companion Loan); provided,
however, that if a Serviced Whole Loan and/or the holder of any related Companion Loan are involved, such expenses, costs
and liabilities will be payable out of funds related to the applicable Serviced Whole Loan in accordance with the related Intercreditor
Agreement and will also be payable out of the other funds in the Collection Account if amounts on deposit with respect to such
Serviced Whole Loan are insufficient therefor. If any such expenses, costs or liabilities relate to a Mortgage Loan or Companion
Loan, then any subsequent recovery on that Mortgage Loan or Companion Loan, as applicable, will be used to reimburse the Trust
for any amounts advanced for the payment of such expenses, costs or liabilities. In such event, the legal expenses and costs of
such action, proceeding, hearing or examination and any liability resulting therefrom shall be expenses, costs and liabilities
of the Trust, and the Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer,
the Asset Representations Reviewer and the Operating Advisor shall be entitled to be reimbursed therefor out of amounts attributable
to the Mortgage Loans or the Companion Loan on deposit in the Collection Account (including, without duplication, any subaccount
thereof), as provided by Section 3.05(a)(xii).

 

(c)            
Each of the Master Servicer and the Special Servicer, as applicable, agrees to indemnify the Depositor, the Trustee, the related
Serviced Companion Noteholder, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer, the Master
Servicer (including in its capacity as Companion Paying Agent) (in the case of the Special Servicer), the Special Servicer (in

fees and related costs, judgments, and any other costs, liabilities, fees and expenses (including costs of enforcement of this
indemnity) that any of them may sustain arising from or as a result of any willful misconduct, bad faith or negligence of the
Master Servicer or the Special Servicer, as the case may be, in the performance of its obligations and duties under this Agreement
or by reason of negligent disregard by the Master Servicer or the Special Servicer, as the case may be, of its duties and obligations

Administrator, the Depositor, the Asset Representations Reviewer or the Operating Advisor, as the case may be, shall immediately
notify the Master Servicer or the Special Servicer, as applicable, if a claim is made by a third party with respect to this Agreement
or the Mortgage Loans entitling the Trust to indemnification hereunder, whereupon the Master Servicer or the Special Servicer,
as the case may be, shall assume the defense of such claim (with counsel reasonably satisfactory to the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or the Depositor) and pay all expenses in connection
therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against
it or them in respect of such claim. Any failure to so notify the Master Servicer or the Special Servicer, as the case may be,
shall not affect any rights any of the foregoing Persons may have to indemnification under this Agreement or otherwise, unless
the Master Servicer’s or the Special Servicer’s, as the case may be, defense of such claim is materially prejudiced
thereby.

 

(d)

judgments, and any other costs, liabilities, fees and expenses (including costs of enforcement of this indemnity) that any of
them may sustain arising from or as a result of any willful misconduct, bad faith or negligence of the Trustee or the Certificate
Administrator, respectively, in the performance of its obligations and duties under this Agreement or by reason of negligent disregard
by the Trustee or the Certificate Administrator, respectively, of its duties and obligations hereunder or by reason of breach
of any representations or warranties made herein; provided that such indemnity shall not cover indirect or consequential
damages. The Depositor, the Master Servicer, the Special Servicer, the Asset Representations Reviewer or the Operating Advisor,
as the case may be, shall immediately notify the Trustee and the Certificate Administrator, respectively, if a claim is made by
a third party with respect to this Agreement or the Mortgage Loans entitling the Trust to indemnification hereunder, whereupon

Depositor, the Master Servicer (including in its capacity as Companion Paying Agent), the Special Servicer, the Asset Representations
Reviewer or the Operating Advisor) and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge
and satisfy any judgment or decree which may be entered against it or them in respect of such claim. Any failure to so notify

them may sustain arising from or as a result of any willful misconduct, bad faith or negligence of the Depositor, in the performance
of its obligations and duties under this Agreement or by reason of negligent disregard by the Depositor of its duties and obligations
hereunder or by reason of breach of any representations or warranties made herein; provided that such indemnity shall not
cover indirect or consequential damages. The Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator,
the Asset Representations Reviewer or the Operating Advisor, as the case may be, shall immediately notify the Depositor if a claim
is made by a third party with respect to this Agreement, whereupon the Depositor shall assume the defense of such claim (with
counsel reasonably satisfactory to the Master Servicer (including in its capacity as Companion Paying Agent) or the Special Servicer)
and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or
decree which may be entered against it or them in respect of such claim. Any failure to so notify the Depositor shall not affect
any rights any of the foregoing Persons may have to indemnification under this Agreement or otherwise, unless the Depositor’s
defense of such claim is materially prejudiced thereby.

 

(f)              The Operating Advisor agrees to indemnify the Master Servicer (including in its capacity as Companion Paying Agent), the Special
Servicer, the Trustee, the Certificate Administrator, the Depositor, the Asset Representations Reviewer and the Trust and any

and duties under this Agreement or by reason of negligent disregard by the Operating Advisor of its duties and obligations hereunder

or consequential damages. The Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator, the Asset Representations
Reviewer or the Depositor, as the case may be, shall immediately notify the Operating Advisor if a claim is made by a third party

Reviewer or the Depositor) and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and
satisfy any judgment or decree which may be entered against it or them in respect of such claim. Any failure to so notify the

(g)             Neither the Operating Advisor nor its Affiliates or any of the partners, directors, officers, shareholders, members, managers,
employees or agents of the Operating Advisor shall be under any liability to any Certificateholder for any action taken or for
refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment;

 

    -393-

     

    

 

provided,
however, that this provision shall not protect the Operating Advisor against any liability which would otherwise be imposed
by reason of willful misconduct, bad faith or negligence in the performance of duties or by reason of negligent disregard of obligations
and duties hereunder.

 

(h)             The Asset Representations Reviewer agrees to indemnify the Master Servicer (including in its capacity as Companion Paying Agent),
the Special Servicer, the Trustee, the Certificate Administrator, the Depositor, the Operating Advisor and the Trust and any partner,

of any willful misconduct, bad faith or negligence of the Asset Representations Reviewer, in the performance of its obligations
and duties under this Agreement or by reason of negligent disregard by the Asset Representations Reviewer of its duties and obligations
hereunder or by reason of breach of any representations or warranties made herein; provided that such indemnity shall not
cover indirect or consequential damages. The Master Servicer, the Special Servicer, the Trustee, the Certificate Administrator,
the Operating Advisor or the Depositor, as the case may be, shall immediately notify the Asset Representations Reviewer if a claim
is made by a third party with respect to this Agreement or the Mortgage Loans entitling the Trust to indemnification hereunder,
whereupon the Asset Representations Reviewer shall assume the defense of such claim (with counsel reasonably satisfactory to the

the Operating Advisor or the Depositor) and pay all expenses in connection therewith, including counsel fees, and promptly pay,
discharge and satisfy any judgment or decree which may be entered against it or them in respect of such claim. Any failure to

fees and expenses incurred in connection with the servicing and administration of a Non-Serviced Mortgage Loan and the related
Non-Serviced Mortgaged Property under the applicable Non-Serviced PSA (as and to the same extent the applicable Non-Serviced Trust
is required to indemnify such parties in respect of other mortgage loans in the applicable Non-Serviced Trust pursuant to the
terms of the related Non-Serviced PSA).

 

The
indemnification provided herein shall survive the termination of this Agreement and the termination or resignation of the Master
Servicer (including in its capacity as

Companion
Paying Agent), the Special Servicer, the Trustee, the Certificate Administrator, the Operating Advisor or the Asset Representations

Section 6.05       
Depositor, Master Servicer and Special Servicer Not to Resign. Subject to the provisions of Section 6.03, neither
the Master Servicer nor the Special Servicer shall resign from their respective obligations and duties hereby imposed on each
of them except upon (a) determination that such party’s duties hereunder are no longer permissible under applicable
law or (b) in the case of the Master Servicer or the Special Servicer, upon the appointment of, and the acceptance of such appointment
by, a successor master servicer or special servicer, as applicable, and receipt by the Certificate Administrator and the Trustee
of Rating Agency Confirmation from each Rating Agency and a confirmation of any applicable rating agencies that such action will
not result in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan
Securities (if any) (provided that such rating agency confirmation may be considered satisfied in the same manner as any
Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25).
Any such determination permitting the resignation of the Master Servicer or the Special Servicer pursuant to clause (a)
above shall be evidenced by an Opinion of Counsel (at the expense of the resigning party) to such effect delivered to the
Trustee and (prior to the occurrence and continuance of a Consultation Termination Event) the Directing Certificateholder. No
such resignation by the Master Servicer or the Special Servicer shall become effective until the Trustee or a successor master
servicer or successor special servicer, as applicable, shall have assumed the Master Servicer’s or the Special Servicer’s,
as applicable, responsibilities and obligations in accordance with Section 7.02 and no such resignation by the Master
Servicer or the Special Servicer shall become effective until the Certificate Administrator shall have filed any required Form
8-K pursuant to Section 11.07 hereof and any other Form 8-K filings have been completed with respect to any related
Companion Loan. Upon any termination (as described in Section 7.01(c)) or resignation of the Master Servicer or the
Special Servicer, pursuant to this Section 6.05, the Master Servicer or the Special Servicer, as applicable, shall
have the right and opportunity to appoint any successor master servicer or special servicer with respect to this Section 6.05;
provided that, such successor master servicer or special servicer shall not be the Asset Representations Reviewer, the
Operating Advisor or one of their respective Affiliates and (prior to the occurrence and continuance of a Control Termination
Event) such successor special servicer is approved by the Directing Holder, such approval not to be unreasonably withheld. The
resigning party shall pay all costs and expenses (including costs and expenses incurred by the Trustee and the Certificate Administrator)
associated with a transfer of its duties pursuant to this Section 6.05. Except as provided in Section 7.01(c),
in no event shall the Master Servicer or the Special Servicer have the right to appoint any successor master servicer or special
servicer if such Master Servicer or Special Servicer, as applicable, is terminated or removed pursuant to Section 7.01.

 

Section 6.06       
Rights of the Depositor in Respect of the Master Servicer and the Special Servicer. The Depositor may, but is not obligated
to, enforce the obligations of the Master Servicer and the Special Servicer hereunder and may, but is not obligated to, perform,
or cause a designee to perform, any defaulted obligation of the Master Servicer and the Special Servicer hereunder or exercise
the rights of the Master Servicer or the Special Servicer, as applicable, hereunder; provided, however, that the
Master Servicer and the Special Servicer shall not be relieved of any of their respective obligations hereunder by virtue of such
performance by

 

    -395-

     

    

 

the
Depositor or its designee. The Depositor shall not have any responsibility or liability for any action or failure to act by the
Master Servicer or the Special Servicer and is not obligated to supervise the performance of the Trustee, the Master Servicer,
the Operating Advisor or the Special Servicer under this Agreement or otherwise.

 

Section 6.07       
The Master Servicer and the Special Servicer as Certificate Owner. The Master Servicer, the Special Servicer or any Affiliate
thereof may become the Holder of (or, in the case of a Book-Entry Certificate, Certificate Owner with respect to) any Certificate
with (except as otherwise set forth in the definition of “Certificateholder”) the same rights it would have if it
were not the Master Servicer, the Special Servicer or an Affiliate thereof.

 

Section 6.08       
The Directing Holder and the Risk Retention Consultation Party. (a)  (A)
The Directing Holder shall be entitled to advise (1) the Special Servicer with respect to all Specially Serviced Loans other
than any applicable Excluded Loan with respect to the Directing Holder or, if the Directing Holder is the Directing Certificateholder,
the Holder of the majority of the Controlling Class, (2) the Special Servicer, with respect to Non-Specially Serviced
Loans (other than any applicable Excluded Loan), as to all matters for which the Master Servicer must obtain the consent or deemed
consent of the Special Servicer (who will have fifteen (15) Business Days, or sixty (60) days, with respect to the determination
of an Acceptable Insurance Default, from the date that the Special Servicer receives the information from the Master Servicer,
to analyze and make a recommendation regarding any of the following actions (provided that, in the event that the Special Servicer
and the Master Servicer have mutually agreed that the Master Servicer will determine and process the request with respect to the
subject following action, if the Special Servicer does not consent, or notify the Master Servicer that it will not consent, to
any of the following actions within the required fifteen (15) Business Days or sixty (60) days, as applicable, the Special Servicer
shall be deemed to have consented to the subject following action)) and (B) the Risk Retention Consultation Party shall (other
than with respect to an Excluded Loan with respect to the Risk Retention Consultation Party or the Holder of the majority of the
VRR Interest) be entitled to consult on a strictly non-binding basis with the Special Servicer with respect to any Major Decision
in respect of a Specially Serviced Loan. For the avoidance of doubt, any consultation with the Risk Retention Consultation Party
under this Agreement shall occur only upon request of the Risk Retention Consultation Party with respect to any individual triggering
event, and any such consultation shall be on a strictly non-binding basis and shall be subject to all limitations with respect
to the procedures and timing for such consultation set forth in this Section 6.08(a). Notwithstanding anything herein
to the contrary, except as set forth in, and in any event subject to Section 6.08(b), to the second and third paragraphs
of this Section 6.08(a), the Master Servicer, shall not be permitted to take any of the following actions, including
with respect to any Mortgage Loan (other than any Non-Serviced Mortgage Loan or any Excluded Loan) or any Serviced Whole Loan,
and for so long as no Control Termination Event has occurred and is continuing, the Special Servicer shall not be permitted to
take any of the following actions (and with respect to the first proviso following the Major Decisions listed below shall not
be permitted to consent to the Master Servicer’s taking any of the following actions as to which the Directing Holder has
objected in writing within ten (10) Business Days (or in the case of a determination of an Acceptable Insurance Default, twenty
(20) days)) after receipt of the written recommendation and analysis from the Special Servicer (provided that if such written
objection has not been received by the Special Servicer within such

 

    -396-

     

    

 

ten
(10) Business Day (or twenty (20) day) period, then such Directing Holder will be deemed to have approved such action):

 

(i)              any proposed or actual foreclosure upon or comparable conversion (which may include acquisitions of an REO Property) of the ownership
of properties securing such of the Mortgage Loans and/or Serviced Whole Loans as come into and continue in default;

 

(ii)             any modification, consent to a modification or waiver of any monetary term (other than late fees and Default Interest) or material

waiver of Default Interest or late payment charges) of a Mortgage Loan or Serviced Whole Loan or any extension of the maturity
date of such Mortgage Loan or Serviced Whole Loan other than as expressly permitted pursuant to the terms of the related Mortgage
Loan documents;

 

(iii)            any sale of a Defaulted Loan or any REO Property (other than in connection with the termination of the Trust) for less than the
applicable Purchase Price (excluding any expenses incurred by the Master Servicer, the Special Servicer, the Depositor, the Certificate
Administrator and the Trustee in respect of the breach or document defect giving rise to a repurchase or substitution obligation
under a Mortgage Loan Purchase Agreement) if the applicable Mortgage Loan Seller makes such Loss of Value Payment within the 90-day
initial cure period or, if applicable, within the subsequent 90-day extended cure period;

 

(iv)            any determination to bring an REO Property into compliance with applicable environmental laws or to otherwise address Hazardous
Materials located at an REO Property;

 

(v)             any release of collateral or any acceptance of substitute or additional collateral for a Mortgage Loan or Serviced Whole Loan
or any consent to either of the foregoing, other than immaterial condemnation actions and other similar takings, or if otherwise
permitted pursuant to the specific terms of the related Mortgage Loan or Serviced Whole Loan and for which there is no lender
discretion;

 

(vi)            any waiver of a “due-on-sale” or “due-on-encumbrance” clause with respect to a Mortgage
Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan if lender consent is required, or any consent to such waiver
or consent to a transfer of the Mortgaged Property or interests in the Mortgagor or consent to the incurrence of additional debt,
other than any such transfer or incurrence of debt as may be effected without the consent of the lender under the related Loan
Agreement or related to an immaterial easement, right of way or similar agreement;

 

(vii)           any property management company changes or franchise changes to the extent the lender is permitted to consent or approve under
the Mortgage Loan documents;

 

(viii)          releases of any escrow accounts, reserve accounts or letters of credit held as performance or “earn-out” escrows or

    -397-

     

    

 

accordance
with the specific terms of the related Mortgage Loan or a Serviced Whole Loan and for which there is no lender discretion;

 

(ix)             any acceptance of an assumption agreement or any other agreement permitting a transfer of interests in a Mortgagor or guarantor
or releasing a Mortgagor or guarantor from liability under a Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced
Whole Loan other than pursuant to the specific terms of such Mortgage Loan or Serviced Whole Loan and for which there is no lender

or similar proceedings under the related Mortgage Loan documents or with respect to the related borrower or Mortgaged Property;

 

(xii)            any modification, waiver or amendment of an Intercreditor Agreement, Co-Lender Agreement or similar agreement with any mezzanine
lender or subordinate debt holder related to a Mortgage Loan or Serviced Whole Loan, or an action to enforce rights with respect
thereto, in each case, in a manner that materially and adversely affects the holders of the Control Eligible Certificates;

 

(xiii)          any proposed modification or waiver of any material provision in the related Mortgage Loan documents governing the type, nature
or amount of insurance coverage required to be obtained and maintained by the related borrower; and

 

(xiv)         
any approval of any casualty insurance settlements or condemnation settlements, and any determination to apply casualty proceeds
or condemnation awards to the reduction of the debt rather than to the restoration of the Mortgaged Property.

 

provided,
however, that notwithstanding the foregoing, the Master Servicer and Special Servicer may mutually agree, as contemplated
by Section 3.18(a) of this Agreement, that the Master Servicer will process and obtain the prior consent of the Special
Servicer with respect to any of the foregoing matters with respect to any Non-Specially Serviced Loan, and, whether processed
by the Master Servicer or not, with respect to a Major Decision in connection with a Non-Specially Serviced Loan, the Master Servicer
and the Special Servicer shall each be entitled to 50% of any Excess Modification Fees and assumption, consent and earnout fees
(other than the assumption application fees and defeasance fees) paid in connection with such matters; 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 the foregoing matters, or (i) any
other matter requiring consent of the Directing Holder with respect to any Mortgage Loan other than an Excluded Loan as to the
Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling
Class, and, with respect to the Directing Certificateholder, prior to the occurrence and continuance of a Control Termination
Event in this Agreement, or (ii) any matter requiring consultation with the Directing

 

    -398-

     

    

 

Certificateholder,
the Risk Retention Consultation Party or the Operating Advisor, is necessary to protect the interests of the Certificateholders
(or, with respect to any Serviced Whole Loan, the interest of the Certificateholders and the holders of any related Serviced Companion
Loan) (as a collective whole (taking into account the subordinate or pari passu nature of any Companion Loans, as the case
may be)), the Special Servicer or Master Servicer, as applicable, may take any such action without waiting for the Directing Holder’s
response (or without waiting to consult with the Directing Holder, the Risk Retention Consultation Party or the Operating Advisor,
as the case may be), provided that the Special Servicer or Master Servicer, as applicable, provides the Directing Holder
(or the Operating Advisor, if applicable) and the Risk Retention Consultation Party with prompt written notice following such
action including a reasonably detailed explanation of the basis therefor; provided, however, that the Special Servicer
is not required to obtain the consent of the Directing Certificateholder for any Major Decision after the occurrence and during
the continuance of a Control Termination Event. In addition, with respect to any Mortgage Loan other than an Excluded Loan as
to such party, for so long as no Control Termination Event has occurred and is continuing, the Directing Certificateholder subject
to any rights, if any, of the related Companion Holder to advise the Special Servicer with respect to the related Serviced Whole
Loan, pursuant to the terms of the related Intercreditor Agreement, may direct the Special Servicer to take, or to refrain from
taking, such other actions with respect to a Mortgage Loan as the Directing Certificateholder may deem advisable or as to which
provision is otherwise made herein.

 

After
the occurrence and during the continuance of a Control Termination Event but prior to the occurrence of a Consultation Termination
Event, the Special Servicer shall consult with the Directing Holder in connection with any Major Decision not relating to any
Non-Serviced Mortgage Loan or Excluded Loan as to such party (and any other actions which otherwise require consultation with
the Directing Certificateholder prior to a Consultation Termination Event hereunder) and the Risk Retention Consultation Party
(only with respect to a Specially Serviced Loan) and consider alternative actions recommended by the Directing Certificateholder
or the Risk Retention Consultation Party, in respect thereof. In the event the Special Servicer receives no response from the
Directing Holder or the Risk Retention Consultation Party within 10 Business Days following its written request for input on any
required consultation, the Special Servicer shall not be obligated to consult with the Directing Holder or the Risk Retention
Consultation Party, respectively, on the specific matter; provided, however, that the failure of the Directing Holder
or the Risk Retention Consultation Party to respond shall not relieve the Special Servicer from consulting with the Directing
Holder or the Risk Retention Consultation Party on any future matters with respect to the related Mortgage Loan (other than a
Non-Serviced Mortgage Loan or any applicable Excluded Loan as to the Directing Certificateholder or the holder of the majority
of the Controlling Class) or Serviced Whole Loan.

 

Notwithstanding
anything herein to the contrary, no such advice, direction or objection by, from or on the part of the Directing Certificateholder,
Operating Advisor or Risk Retention Consultation Party contemplated in this Section 6.08(a), may require or cause
the Master Servicer or Special Servicer to violate any provision of any Mortgage Loan or related Intercreditor Agreement, applicable
law, this Agreement, or the REMIC Provisions (and, with respect to a Serviced Whole Loan, subject to the rights of the holders
of the related Companion Loan), including without limitation the obligation of the Master Servicer and the Special Servicer

 

    -399-

     

    

 

to
act in accordance with the Servicing Standard, or expose the Master Servicer, the Special Servicer, the Certificate Administrator,
the Operating Advisor, the Asset Representations Reviewer, the Trust or the Trustee to liability, or materially expand the scope
of the responsibilities of the Master Servicer or the Special Servicer, as applicable, hereunder or cause the Master Servicer
or the Special Servicer, as applicable, to act, or fail to act, in a manner which in the reasonable judgment of the Master Servicer
or the Special Servicer, as the case may be, is not in the best interests of the Certificateholders. In the event the Special
Servicer or the Master Servicer, as applicable, determines that a refusal to consent by the Directing Certificateholder or any
advice from the Operating Advisor, the Directing Certificateholder or the Risk Retention Consultation Party, would cause the Special
Servicer or Master Servicer, as applicable, to violate the terms of any Mortgage Loan, applicable law or this Agreement, including
without limitation, the Servicing Standard, the Special Servicer or the Master Servicer, as applicable, shall disregard such refusal
to consent or advise and notify the Operating Advisor, the Directing Certificateholder or the Risk Retention Consultation Party,
respectively, and the Trustee and the Rating Agencies of its determination, including a reasonably detailed explanation of the
basis therefor. The taking of, or refraining from taking, any action by the Master Servicer or the Special Servicer in accordance
with the direction of or approval of the Directing Certificateholder and the Operating Advisor or the approval of the Risk Retention
Consultation Party that does not violate the terms of any Mortgage Loan, applicable law or the Servicing Standard or any other
provisions of this Agreement, will not result in any liability on the part of the Master Servicer or the Special Servicer.

 

The
Directing Holder shall have no liability to the Trust or the Certificateholders for any action taken, or for refraining from the
taking of any action, or for errors in judgment; provided, however, that the Directing Holder shall not be protected
against any liability to a Controlling Class Certificateholder that would otherwise be imposed by reason of willful misconduct,
bad faith or negligence in the performance of duties owed to the Controlling Class Certificateholders or by reason of reckless
disregard of obligations or duties owed to the Controlling Class Certificateholders. By its acceptance of a Certificate, each
Certificateholder acknowledges and agrees that the Directing Holder may take actions that favor the interests of one or more Classes
of Certificates including the Holders of the Controlling Class over other Classes of the Certificates, and that the Directing
Certificateholder may have special relationships and interests that conflict with those of Holders of some Classes of the Certificates,
that the Directing Holder may act solely in the interests of the Holders of the Controlling Class, including the Holders of the
Controlling Class, that the Directing Holder does not have any duties or liability to the Holders of any Class of Certificates
other than the Controlling Class, that the Directing 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, and that the Directing Holder shall have no liability whatsoever
for having so acted, and no Certificateholder may take any action whatsoever against the Directing Holder or any director, officer,
employee, agent or principal thereof for having so acted.

 

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

 

    -400-

     

    

 

owed
to the Holders of the VRR Interest or by reason of reckless disregard of obligations or duties owed to the Holders of the VRR
Interest. By its acceptance of a Certificate, each Certificateholder acknowledges and agrees that the Risk Retention Consultation
Party may take actions that favor the interests of one or more Classes of the Certificates including the Holders of an VRR Interest
over other Classes of the Certificates, and that the Risk Retention Consultation Party may have special relationships and interests
that conflict with those of Holders of some Classes of the Certificates, that the Risk Retention Consultation Party may act solely
in the interests of the Holders of an VRR Interest, that the Risk Retention Consultation Party does not have any duties or liability
to the Holders of any Class of Certificates other than the VRR Interest, that the Risk Retention Consultation Party shall not
be liable to any Certificateholder, by reason of its having acted solely in the interests of the Holder of the VRR Interest, and
that the Risk Retention Consultation Party shall have no liability whatsoever for having so acted, and no Certificateholder may
take any action whatsoever against the Risk Retention Consultation Party or any director, officer, employee, agent or principal
thereof for having so acted.

 

Any
Non-Serviced Whole Loan Controlling Holder, with respect to a Non-Serviced Whole Loan, shall have no liability to the Trust
or the Certificateholders for any action taken, or for refraining from the taking of any action, or for errors in judgment. By
its acceptance of a Certificate, each Certificateholder acknowledges and agrees that any such Non-Serviced Whole Loan Controlling
Holder, with respect to the related Non-Serviced Whole Loan, may take actions that favor the interests of one or more classes
of the certificates issued under the related Non-Serviced PSA including the Holders of the controlling class under such Non-Serviced
PSA over other Classes of the Certificates, and that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced
Whole Loan, may have special relationships and interests that conflict with those of Holders of some Classes of the Certificates,
that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, may act solely in the interests
of the Holders of the controlling class under the related Non-Serviced PSA, that such Non-Serviced Whole Loan Controlling Holder,
shall not be liable to any Certificateholder, by reason of its having acted solely in the interests of the Holders of the controlling
class under the related Non-Serviced PSA, and that such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced
Whole Loan, shall have no liability whatsoever for having so acted, and no Certificateholder may take any action whatsoever against
such Non-Serviced Whole Loan Controlling Holder, with respect to such Non-Serviced Whole Loan, or any director, officer, employee,
agent or principal thereof for having so acted.

 

(b)             Notwithstanding anything to the contrary contained herein (i) after the occurrence and during the continuance of a Control
Termination Event (and at any time with respect to any Excluded Loan with respect to the Directing Holder or, if the Directing
Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class), the Directing Holder shall have
no right to consent to or direct any action taken or not taken by any party to this Agreement; (ii) after the occurrence
and during the continuance of a Control Termination Event but prior to the occurrence and continuance of a Consultation Termination
Event, the Directing Holder shall remain entitled to receive any notices, reports or information to which it is entitled pursuant
to this Agreement, and the Special Servicer and any other applicable party shall consult with the Directing Holder (other than
with respect to any Excluded Loan as to such party) to the extent set forth herein in connection with any action to be taken or
refrained from taking; and (iii) after the occurrence and continuance of a Consultation Termination Event,

 

    -401-

     

    

 

the
Directing Holder (at any time with respect to any Excluded Loan as to either such party) shall have no direction, consultation
or consent rights hereunder and no right to receive any notices, reports or information (other than notices, reports or information
required to be delivered to all Certificateholders) or any other rights as Directing Holder.

 

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

 

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

 

In
addition, if an Operating Advisor Consultation Event has occurred and is continuing, the Special Servicer will also be required
to consult with the Operating Advisor in connection with any proposed Major Decision (and any other actions which otherwise require
consultation with the Operating Advisor) and consider alternative actions recommended by the Operating Advisor, in respect thereof,
provided that such consultation is on a non-binding basis. In the event that the Special Servicer receives no response
from the Operating Advisor within ten (10) days following the later of (i) its written request for input (which request is
required to include the related Major Decision Reporting Package) on any required consultation and (ii) delivery of all such
additional information reasonably requested by the Operating Advisor that is in the possession of the Special Servicer related
to the subject matter of such consultation, the Special Servicer shall not be obligated to consult with the Operating Advisor
on the specific matter; provided, however, that the failure of the Operating Advisor to respond on any specific
matters shall not relieve the Special Servicer from its obligation to consult with the Operating

 

    -402-

     

    

 

Advisor
on any future matter with respect to the applicable Mortgage Loan or any other Mortgage Loan. Notwithstanding anything herein
to the contrary, with respect to any Excluded Loan (regardless of whether an Operating Advisor Consultation Event has occurred
and is continuing), the Special Servicer shall consult with the Operating Advisor, on a non-binding basis, in connection with
the related transactions involving proposed Major Decisions that it is processing and consider alternative actions recommended
by the Operating Advisor, in respect thereof, in accordance with the procedures set forth in this Section 6.08 for
consulting with the Operating Advisor.

 

In
connection with the Directing Certificateholder’s or Operating Advisor’s right to consent or consult with respect
to a Major Decision, as applicable, if the Special Servicer determines that action is necessary to protect the related Mortgaged
Property or the interests of the Certificateholders from potential harm if such action is not taken, or if a failure to take any
such action at such time would be inconsistent with Accepted Servicing Practices, the Special Servicer may take actions with respect
to the related Mortgaged Property before the expiration of the applicable period for the Operating Advisor or Directing Certificateholder
to respond as described in this section, if the Special Servicer reasonably determines in accordance with Accepted Servicing Practices
that failure to take such actions before the expiration of such period would materially adversely affect the interest of the Certificateholders,
and the Special Servicer has made a reasonable effort to contact the Operating Advisor or the Directing Certificateholder, as
applicable.

 

In
addition, (i) for so long as no Consultation Termination Event is continuing, with respect to any Specially Serviced Loan (other
than any Non-Serviced Mortgage Loan or any applicable Excluded Loan) and (ii) during the continuance of a Consultation Termination
Event, with respect to any Mortgage Loan (other than any Non-Serviced Mortgage Loan or applicable Excluded Loan), the Special
Servicer will also be required to consult with the Risk Retention Consultation Party in connection with any Major Decision that
it is processing (and such other matters that are subject to consultation rights of the Risk Retention Consultation Party pursuant
to this Agreement) and to consider alternative actions recommended by the Risk Retention Consultation Party in respect of such
Major Decision; provided that such consultation is on a non-binding basis. In the event the Master Servicer or the Special
Servicer, as applicable, receives no response from the Risk Retention Consultation Party within 10 days following the later of
(i) the Special Servicer’s, written request for input (which request is required to include the related Major Decision
Reporting Package) on any required consultation and (ii) delivery of all such additional information reasonably requested
by the Risk Retention Consultation Party and reasonably available to the Special Servicer related to the subject matter of such
consultation, the Master Servicer or the Special Servicer, as applicable, will not be obligated to consult with the Risk Retention
Consultation Party on the specific matter; provided, however, that the failure of the Risk Retention Consultation
Party to respond shall not relieve the Master Servicer or the Special Servicer, as applicable, using reasonable efforts to consult
with the Risk Retention Consultation Party on any future matters with respect to the applicable Mortgage Loan or Serviced Whole
Loan or any other Mortgage Loan.

 

After
the occurrence and during the continuance of a Consultation Termination Event, the Directing Certificateholder shall have no consultation
or consent rights hereunder and shall have no right to receive any notices, reports or information (other than notices, reports
or

 

    -403-

     

    

 

information
required to be delivered to all Certificateholders) or any other rights as Directing Certificateholder. However, the Directing
Certificateholder shall maintain the right to exercise its Voting Rights for the same purposes as any other Certificateholder.

 

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

    -406-

     

    

 

Termination
Event shall not have been remedied, the Trustee or the Depositor may, and at the written direction of ((i) for so long as
a Control Termination Event has not occurred and is not continuing and (ii) other than with respect to any Excluded Loan
as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling
Class) the Directing Holder (solely with respect to the Special Servicer) or the Holders of Certificates entitled to more than
25% of the Voting Rights, the Trustee shall, terminate (and the Depositor may direct the Trustee to terminate each of the Master
Servicer or the Special Servicer, as applicable, upon five Business Days’ written notice if there is a Servicer Termination
Event under clause (iii)(A) above), by notice in writing to the Affected Party, with a copy of such notice to the
Depositor and the Operating Advisor, all of the rights (subject to Section 3.11 and Section 6.04) and
obligations of the Affected Party under this Agreement and in and to the Mortgage Loans and the proceeds thereof (other than as
a Certificateholder or Companion Holder, if applicable); provided, however, that the Affected Party shall be entitled
to the payment of accrued and unpaid compensation and reimbursement through the date of such termination as provided for under
this Agreement for services rendered and expenses incurred. From and after the receipt by the Affected Party of such written notice
except as otherwise provided in this Article VII, all authority and power of the Affected Party under this Agreement,
whether with respect to the Certificates (other than as a Holder of any Certificate) or the Mortgage Loans or otherwise, shall
pass to and be vested in the Trustee with respect to a termination of the Master Servicer or the Special Servicer pursuant to
and under this Section 7.01, and, without limitation, the Trustee is hereby authorized and empowered to execute and
deliver, on behalf of and at the expense of the Affected Party, as attorney-in-fact or otherwise, any and all documents
and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such
notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents,
or otherwise. The Master Servicer and the Special Servicer each agree that if it is terminated pursuant to this Section 7.01(b),
it shall promptly (and in any event no later than twenty (20) Business Days subsequent to its receipt of the notice of termination)
provide the Trustee with all documents and records requested by it to enable it to assume the Master Servicer’s or the Special
Servicer’s, as the case may be, functions hereunder, and shall cooperate with the Trustee in effecting the termination of
the Master Servicer’s or the Special Servicer’s, as the case may be, responsibilities and rights (subject to Section 3.11
and Section 6.04) hereunder, including, without limitation, the transfer within five (5) Business Days to the
Trustee for administration by it of all cash amounts which shall at the time be or should have been credited by the Master Servicer
to the Collection Account or any Servicing Account (if it is the Affected Party), by the Special Servicer to the REO Account (if
it is the Affected Party) or thereafter be received with respect to the Mortgage Loans or any REO Property (provided, however,
that the Master Servicer and the Special Servicer each shall, if terminated pursuant to this Section 7.01(b) or pursuant
to Section 7.01(d) (with respect to the Special Servicer), continue to be entitled to receive all amounts accrued
or owing to it under this Agreement on or prior to the date of such termination, whether in respect of Advances (in the case of
the Special Servicer or the Master Servicer) or otherwise, and it and its Affiliates and the directors, managers, officers, members,
employees and agents of it and its Affiliates shall continue to be entitled to the benefits of Section 3.11 and Section 6.04
notwithstanding any such termination).

 

(c)            
If the Master Servicer receives notice of termination under Section 7.01(b) solely due to a Servicer Termination Event
under Section 7.01(a)(viii) or (a)(ix), the Master

 

    -407-

     

    

 

Servicer
shall have a forty-five (45) day period after such notice in which to find a successor master servicer qualified to act as
Master Servicer hereunder in accordance with Section 6.03 and Section 7.02 and to which the Master Servicer
can sell its rights to service the Mortgage Loans under this Agreement. During such forty-five (45) day period the Master
Servicer may continue to serve as Master Servicer hereunder. In the event that the Master Servicer is unable, within such forty-five
(45) day period, to cause a qualified successor master servicer to assume the duties of the Master Servicer hereunder, then and
in such event, the Trustee shall assume the obligations of the Master Servicer hereunder.

 

Notwithstanding
Section 7.01(b), if any Servicer Termination Event on the part of the Special Servicer shall occur and be continuing
that affects the Holder of a Serviced Pari Passu Companion Loan, then, so long as the Special Servicer is not otherwise terminated,
the Holder of such Serviced Pari Passu Companion Loan or the Other Trustee appointed under the related Other Pooling and Servicing
Agreement, as applicable, shall be entitled to direct the Trustee to terminate the Special Servicer with respect to the related
Serviced Pari Passu Whole Loan. Any Special Servicer appointed to replace the Special Servicer with respect to a Serviced Pari
Passu Mortgage Loan cannot at any time be (without the prior written consent of the holder of such Serviced Pari Passu Companion
Loan) the person (or Affiliate thereof) that was terminated at the direction of the holder of the related Serviced Pari Passu
Companion Loan. Any such Special Servicer under this paragraph shall meet the eligibility requirements of Section 7.02
and the eligibility requirements of the related Other Pooling and Servicing Agreement, and the appointment thereof shall comply
with the provisions of Section 7.02. Any appointment of a replacement special servicer in accordance with this paragraph
shall be subject to the receipt of Rating Agency Confirmation and confirmation from the rating agencies that such appointment
or replacement will not result in the downgrade, withdrawal or qualification of the then-current ratings of any class of any
related Serviced Companion Loan Securities (provided that such rating agency confirmation may be considered satisfied in
the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25).

 

(d)              
Subject to the right of the Operating Advisor to recommend the termination of the Special Servicer and recommend a Qualified Replacement
Special Servicer and the right of the applicable Certificateholders to approve the replacement of the Special Servicer with such
Qualified Replacement Special Servicer pursuant to this Section 7.01(d), and subject to the rights of the holder of
a related AB Subordinate Companion Loan pursuant to the related Intercreditor Agreement, at any time prior to the occurrence and
continuance of a Control Termination Event and other than with respect to any Excluded Loan with respect to the Directing Certificateholder
or the Holder of the majority of the Controlling Class, the Directing Certificateholder shall be entitled to terminate the rights
(subject to Section 3.11 and Section 6.04) and obligations of the Special Servicer under this Agreement,
with or without cause, upon ten (10) Business Days’ notice to the Special Servicer, the Master Servicer, the Certificate
Administrator, the Trustee and the Operating Advisor; such termination to be effective upon the appointment of a successor special
servicer meeting the requirements of this Section 7.01(d). Upon a termination of the Special Servicer, the Directing
Certificateholder (other than with respect to any Excluded Loan with respect to the Directing Certificateholder or the Holder
of the majority of the Controlling Class) shall designate a successor special servicer; provided, however, that
(i) such successor will meet the requirements set forth in Section 7.02,

 

    -408-

     

    

 

(ii) each
Rating Agency delivers Rating Agency Confirmation and, in the case of any class of any Serviced Companion Loan Securities the
applicable rating agencies deliver a confirmation that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in the same
manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25)
and (iii) no replacement of the Special Servicer shall be effective until the Certificate Administrator shall have filed
any required Form 8-K pursuant to Section 11.07 hereof and any other Form 8-K filings have been completed with respect
to any related Companion Loan.

 

After
the occurrence and during the continuance of a Control Termination Event, upon (a) the written direction of Holders of Principal
Balance Certificates evidencing not less than 25% of the Voting Rights (taking into account the application of any Appraisal Reduction
Amounts to notionally reduce the Certificate Balances pursuant to Section 4.05 hereof) of the Principal Balance Certificates
requesting a vote to replace the Special Servicer with a new special servicer designated in such written direction, (b) payment
by such Holders to the Certificate Administrator of the reasonable fees and expenses (including any legal fees and any Rating
Agency fees and expenses) to be incurred by the Certificate Administrator in connection with administering such vote and which
shall not be additional expenses of the Trust and (c) delivery by such Holders to the Certificate Administrator and Trustee of
Rating Agency Confirmation from each Rating Agency (which Rating Agency Confirmation shall be obtained at the expense of such
Holders), the Certificate Administrator shall promptly post notice to all Certificateholders of such request on the Certificate
Administrator’s Website in accordance with Section 3.13(b) and concurrently by mail, and conduct the solicitation
of votes of all Certificates in such regard, which vote shall occur within one hundred eighty (180) days of the posting of such
notice. Upon the written direction of (a) Holders of Principal Balance Certificates evidencing at least 66 2/3% of a Certificateholder
Quorum or (b) Holders of Non-Reduced Certificates evidencing more than 50% of the aggregate Voting Rights of each Class of
Non-Reduced Certificates, the Trustee shall terminate all of the rights and obligations of such Special Servicer under this Agreement
and appoint the successor special servicer (which must be a Qualified Replacement Special Servicer) designated by such Certificateholders.

 

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

 

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

 

    -409-

     

    

 

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

 

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

 

    -410-

     

    

 

sentence
within 180 days of the posting of the notice to the Certificate Administrator’s Website, then the Trustee shall have no
obligation to remove the Special Servicer. Prior to the appointment of any replacement special servicer, such replacement special
servicer shall have agreed to succeed to the obligations of the Special Servicer under this Agreement and to act as the Special
Servicer’s successor hereunder. In the event the Special Servicer is terminated pursuant to this Section 7.01(d),
the Directing Holder may not subsequently reappoint such terminated Special Servicer or any Risk Retention Affiliate thereof.

 

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

 

For
the avoidance of doubt, the indemnification of the Operating Advisor in Section 6.04 shall include, subject to the
limitations set forth in Section 6.04, any action or claim arising from, or relating to, the Operating Advisor’s
determination under this Section 7.01(d) (regarding removal of the Special Servicer), or the result of the vote of
the Certificateholders (regarding removal of the Special Servicer).

 

(e)            
The Master Servicer and the Special Servicer shall, as the case may be, from time to time, take all such reasonable actions as
are required by it in accordance with the related Servicing Standard in order to prevent the Certificates from being placed on
“watch” status or downgraded due to servicing or special servicing, as applicable, concerns by any Rating Agency.
In no event shall the remedy for a breach of the foregoing covenant extend beyond termination pursuant to Section 7.01(a)(viii)
and Section 7.01(a)(ix) and the resulting operation of Section 7.01(b) and (c). The operation
of this subsection (e) shall not be construed to limit the effect of Section 7.01(a)(viii) and Section 7.01(a)(ix).

 

(f)            
Notwithstanding the foregoing, (1) if any Servicer Termination Event on the part of the Master Servicer affects a Serviced Companion
Loan, any related Serviced Companion Noteholder or the rating on any class of certificates backed, wholly or partially, by any
Serviced Companion Loan Securities, and if the Master Servicer is not otherwise terminated, or (2) if a Servicer Termination Event
on the part of the Master Servicer affects only a Serviced Companion Loan, any related Serviced Companion Noteholder or the rating
on any class of certificates backed, wholly or partially, by any Serviced Companion Loan Securities, then the Master Servicer
may not be terminated by or at the direction of such Serviced Companion Noteholder or the holders of any certificates backed,
wholly or partially, by such Serviced Companion Loan, but upon the written direction of such Serviced Companion Noteholder, the
Master Servicer shall be required to appoint a sub-servicer that will be responsible for servicing the related Serviced Whole
Loan.

 

(g)            
Notwithstanding anything to the contrary contained in this Section 7.01, with respect to any Excluded Special Servicer
Loan, if any, the related Special Servicer shall resign as Special Servicer of that Excluded Special Servicer Loan. Prior to the
occurrence and continuance of a Control Termination Event, if the applicable Excluded Special Servicer Loan is not also an Excluded
Loan as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of
the Controlling Class, the Directing Holder shall

 

    -411-

     

    

 

select
an Excluded Special Servicer, as successor to the resigning Special Servicer, for the related Excluded Special Servicer Loan in
accordance with this Agreement. After the occurrence and during the continuance of a Control Termination Event or if the Directing
Certificateholder or the majority Controlling Class Certificateholder on its behalf fails to make the selection contemplated by
the prior sentence within ten (10) Business Days or if at any time the applicable Excluded Special Servicer Loan is also an Excluded
Loan as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of
the Controlling Class, the resigning Special Servicer shall use reasonable efforts to select the related Excluded Special Servicer.
The Special Servicer shall not have any liability with respect to the actions or inactions of the applicable Excluded Special
Servicer or with respect to the identity of the applicable Excluded Special Servicer so long as the selected Excluded Special
Servicer is a Qualified Replacement Special Servicer. It shall be a condition to any such appointment that (i) the Rating
Agencies confirm that the appointment would not result in a qualification, downgrade or withdrawal of any of their then-current
ratings of the Certificates and each NRSRO hired to provide ratings with respect to any Serviced Companion Loan Securities makes
the equivalent confirmation, (ii) the related Excluded Special Servicer is a Qualified Replacement Special Servicer and (iii) the
related Excluded Special Servicer delivers to the Depositor and the Certificate Administrator and any applicable Other Depositor
and Other Certificate Administrator, the information, if any, required under Item 6.02 of Form 8-K pursuant to the
Exchange Act regarding itself in its role as Excluded Special Servicer.

 

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

 

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

 

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

 

    -412-

     

    

 

Section 7.02       
Trustee to Act; Appointment of Successor. On and after the time the Master Servicer or the Special Servicer, as the case
may be, either resigns pursuant to subsection (a) of the first sentence of Section 6.05 or receives a notice
of termination for cause pursuant to Section 7.01(b), and provided that no acceptable successor has been appointed
within the time period specified in Section 7.01(c), the Trustee shall be the successor to such party, until such
successor to the Master Servicer or the Special Servicer, as applicable, is appointed as provided in this Section 7.02
or by the Directing Holder as provided in Section 7.01(d), as applicable, in all respects in its capacity as Master
Servicer or the Special Servicer, as applicable, under this Agreement and the transactions set forth or provided for herein and
shall be subject to, and have the benefit of, all of the rights, (subject to Section 3.11 and Section 6.04)
benefits, responsibilities, duties, liabilities and limitations on liability relating thereto and that arise thereafter placed
on or for the benefit of the Master Servicer or the Special Servicer, as applicable, by the terms and provisions hereof; provided,
however, that any failure to perform such duties or responsibilities caused by the terminated party’s failure under
Section 7.01 to provide information or moneys required hereunder shall not be considered a default by such successor
hereunder. The appointment of a successor master servicer shall not affect any liability of the predecessor Master Servicer which
may have arisen prior to its termination as Master Servicer, and the appointment of a successor special servicer shall not affect
any liability of the predecessor Special Servicer which may have arisen prior to its termination as Special Servicer. The Trustee
in its capacity as successor to the Master Servicer or the Special Servicer, as the case may be, shall not be liable for any of
the representations and warranties of the Master Servicer or the Special Servicer, respectively, herein or in any related document
or agreement, for any acts or omissions of the predecessor master servicer or special servicer or for any losses incurred by the
predecessor Master Servicer pursuant to Section 3.06 hereunder, nor shall the Trustee be required to purchase any
Mortgage Loan hereunder solely as a result of its obligations as successor master servicer or special servicer, as the case may
be. Subject to Section 3.11, as compensation therefor, the Trustee as successor master servicer shall be entitled
to the Servicing Fees and all fees relating to the Mortgage Loans, the Companion Loans that the Master Servicer would have been
entitled to if the Master Servicer had continued to act hereunder, including but not limited to any income or other benefit from
any Permitted Investment pursuant to Section 3.06, and subject to Section 3.11, and the Trustee as successor
to the Special Servicer shall be entitled to the Special Servicing Fees to which the Special Servicer would have been entitled
if the Special Servicer had continued to act hereunder. Should the Trustee succeed to the capacity of the Master Servicer or the
Special Servicer, as the case may be, the Trustee shall be afforded the same standard of care and liability as the Master Servicer
or the Special Servicer, as applicable, hereunder notwithstanding anything in Section 8.01 to the contrary, but only
with respect to actions taken by it in its role as successor master servicer or successor special servicer, as the case may be,
and not with respect to its role as Trustee hereunder. Notwithstanding the above, the Trustee may, if it shall be unwilling to
act as successor to the Master Servicer or the Special Servicer, as applicable, or shall, if it is unable to so act, or if the
Trustee is not approved as a servicer by each Rating Agency, or if the Directing Holder ((i) prior to the occurrence and
continuance of a Control Termination Event and (ii) other than with respect to any Excluded Loan with respect to the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class) or
the Holders of Certificates entitled to a majority of the Voting Rights, so request in writing to the Trustee, promptly appoint,
or petition a court of competent jurisdiction to appoint, any established

 

    -413-

     

    

 

mortgage
loan servicing institution or other entity which meets the criteria set forth in Section 6.05 and otherwise herein,
as the successor to the Master Servicer or the Special Servicer, as applicable, hereunder in the assumption of all or any part
of the responsibilities, duties or liabilities of the Master Servicer or the Special Servicer hereunder. No appointment of a successor
to the Master Servicer or the Special Servicer hereunder shall be effective until (i) the assumption in writing by the successor
to the Master Servicer or the Special Servicer of all its responsibilities, duties and liabilities hereunder that arise thereafter,
(ii) upon receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion
Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner as
any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section 3.25),
(iii) which appointment has been approved (prior to the occurrence and continuance of a Control Termination Event) by the
Directing Holder, such approval not to be unreasonably withheld and (iv) the Certificate Administrator shall have filed any
required Form 8-K pursuant to Section 11.07 and any other Form 8-K filings have been completed with respect to any
related Companion Loan. Pending appointment of a successor to the Master Servicer or the Special Servicer hereunder, unless the
Trustee shall be prohibited by law from so acting, the Trustee shall act in such capacity as herein above provided. In connection
with such appointment and assumption of a successor to the Master Servicer or the Special Servicer as described herein, the Trustee
may make such arrangements for the compensation of such successor out of payments on the Mortgage Loans as it and such successor
shall agree; provided, however, that no such compensation with respect to a successor master servicer or successor
special servicer, as the case may be, shall be in excess of that permitted the terminated Master Servicer or Special Servicer,
as the case may be, hereunder. The Trustee, the Master Servicer or the Special Servicer (whichever is not the terminated party)
and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.
Any costs and expenses associated with the transfer of the servicing function (other than with respect to a termination without
cause) under this Agreement shall be borne by the predecessor Master Servicer or Special Servicer, as applicable. If such predecessor
Master Servicer or Special Servicer (as the case may be) has not reimbursed the party requesting such termination or the successor
master servicer or special servicer for such expenses within 90 days after the presentation of reasonable documentation,
such expense shall be reimbursed by the Trust; provided that the terminated Master Servicer or Special Servicer shall not
thereby be relieved of its liability for such expenses. If and to the extent that the terminated Master Servicer or Special Servicer
has not reimbursed such costs and expenses, the party requesting such termination shall have an affirmative obligation to take
all reasonable actions to collect such expenses on behalf of the Trust. In the event of a termination without cause, such costs
and expenses shall be borne by the party requesting such termination, or as otherwise set forth herein; provided that the
Certificate Administrator and the Trustee shall not bear any such costs and expenses. For the avoidance of doubt, if the Trustee
is terminating the Master Servicer or Special Servicer in accordance with this Agreement at the direction of any party or parties
permitted to direct the Trustee to so terminate the Master Servicer or the Special Servicer pursuant to this Agreement, the Trustee
shall not have any liability for such expenses pursuant to this paragraph.

 

Section 7.03       
Notification to Certificateholders. (a)  Upon any resignation
of the Master Servicer or the Special Servicer pursuant to Section 6.05, any termination of the Master

 

    -414-

     

    

 

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

 

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

 

Section 7.04       
Waiver of Servicer Termination Events. The Holders of Certificates representing at least 66-2/3% of the Voting Rights allocated
to each Class of Certificates affected by any Servicer Termination Event hereunder may waive such Servicer Termination Event,
within twenty (20) days of the receipt of notice from the Certificate Administrator of the occurrence of such Servicer Termination
Event; provided, however, that (1) a Servicer Termination Event under clause (i) or (ii) of Section 7.01(a)
may be waived only by all of the Certificateholders of the affected Classes and (2) a Servicer Termination Event under clause (iii)
or (ix) of Section 7.01(a) relating to Exchange Act reporting may be waived only with the consent of the Depositor,
together with (in the case of each of clauses (1) and (2) of this sentence) the consent of each Serviced Companion Noteholder,
if any, that is affected by such Servicer Termination Event. Upon any such waiver of a Servicer Termination Event, such Servicer
Termination Event shall cease to exist and shall be deemed to have been remedied for every purpose hereunder. Upon any such waiver
of a Servicer Termination Event by Certificateholders, the Trustee and the Certificate Administrator shall be entitled to recover
all costs and expenses incurred by it in connection with enforcement action taken with respect to such Servicer Termination Event
prior to such waiver from the Trust. No such waiver shall extend to any subsequent or other Servicer Termination Event or impair
any right consequent thereon except to the extent expressly so waived. Notwithstanding any other provisions of this Agreement,
for purposes of waiving any Servicer Termination Event pursuant to this Section 7.04, Certificates registered in the
name of the Depositor or any Affiliate of the Depositor shall be entitled to the same Voting Rights with respect to the matters
described above as they would if any other Person held such Certificates.

 

Section 7.05       
Trustee as Maker of Advances. In the event that the Master Servicer fails to fulfill its obligations hereunder to make
any Advances and such failure remains uncured, the Trustee shall perform such obligations (x) within five (5) Business Days
following such failure by the Master Servicer with respect to Servicing Advances resulting in a Servicer Termination Event under
Section 7.01(a)(iii) hereof to the extent a Responsible Officer of the Trustee has actual knowledge of such failure
with respect to such Servicing Advances and (y) by noon, New York City time, on the related Distribution Date with respect
to P&I Advances pursuant to the Certificate Administrator’s notice of failure pursuant to Section 4.03(a) unless
such failure has been cured. With respect to any such Advance made by the Trustee, the Trustee shall succeed to all of the Master
Servicer’s rights with respect to Advances hereunder, including, without limitation, the Master Servicer’s rights
of reimbursement and interest on each

 

    -415-

     

    

 

Advance
at the Reimbursement Rate, and rights to determine that a proposed Advance is a Nonrecoverable P&I Advance or Servicing Advance,
as the case may be, (without regard to any impairment of any such rights of reimbursement caused by such Master Servicer’s
default in its obligations hereunder); provided, however, that if Advances made by the Trustee and the Master Servicer
shall at any time be outstanding, or any interest on any Advance shall be accrued and unpaid, all amounts available to repay such
Advances and the interest thereon hereunder shall be applied entirely to the Advances outstanding to the Trustee, until such Advances
shall have been repaid in full, together with all interest accrued thereon, prior to reimbursement of the Master Servicer for
such Advances. The Trustee shall be entitled to conclusively rely on any notice given with respect to a Nonrecoverable Advance
hereunder.

set forth in this Agreement. If a Servicer Termination Event occurs and is continuing, the Trustee shall exercise such of the
rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise as a prudent person

pursuant to any provision of this Agreement (other than the Mortgage Files, the review of which is specifically governed by the
terms of Article II), shall examine them to determine whether they conform to the requirements of this Agreement. If any
such instrument is found not to conform to the requirements of this Agreement in a material manner, the Trustee or the Certificate
Administrator shall notify the party providing such instrument and requesting the correction thereof. The Trustee or the Certificate
Administrator shall not be responsible for the accuracy or content of any resolution, certificate, statement, opinion, report,

and accepted by the Trustee or the Certificate Administrator in good faith, pursuant to this Agreement.

 

(c)             No provision of this Agreement shall be construed to relieve the Trustee or the Certificate Administrator from liability for its
own negligent action, its own negligent failure to act or its own willful misconduct or bad faith; provided, however,
that:

 

(i)            Prior to the occurrence of a Servicer Termination Event, and after the curing of all such Servicer Termination Events which may
have occurred, the duties and

 

    -416-

     

    

 

obligations
of the Trustee and the Certificate Administrator shall be determined solely by the express provisions of this Agreement, the Trustee
and the Certificate Administrator shall not be liable except for the performance of such duties and obligations as are specifically
set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and the
Certificate Administrator and, in the absence of bad faith on the part of the Trustee and the Certificate Administrator, the Trustee
and the Certificate Administrator may conclusively rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon any certificates or opinions furnished to the Trustee or the Certificate Administrator and conforming
to the requirements of this Agreement;

 

(ii)          
Neither the Trustee nor the Certificate Administrator, as applicable, shall be liable for an error of judgment made in good faith
by a Responsible Officer or Responsible Officers of the Trustee or the Certificate Administrator, respectively, unless it shall
be proved that the Trustee or the Certificate Administrator, as applicable, was negligent in ascertaining the pertinent facts;
and

 

(iii)         
Neither the Trustee nor the Certificate Administrator, as applicable, shall be liable with respect to any action taken, suffered
or omitted to be taken by it in good faith in accordance with the direction of Holders of Corresponding Certificates entitled
to greater than 25% of the Percentage Interest of each affected Class of Regular Interests, or of the aggregate Voting Rights
of the Certificates, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee
or the Certificate Administrator, or exercising any trust or power conferred upon the Trustee or the Certificate Administrator,
under this Agreement (unless a higher percentage of Voting Rights is required for such action).

 

(d)           
The Certificate Administrator shall make available via its internet website initially located at www.ctslink.com to the Serviced
Companion Noteholders all reports that the Certificate Administrator has made available to Certificateholders under this Agreement
to the extent such reports relate to the related Serviced Companion Loan and upon the submission of an Investor Certification
pursuant to this Agreement.

 

Section 8.02       
Certain Matters Affecting the Trustee and the Certificate Administrator. Except as otherwise provided in Section 8.01:

 

(i)           
The Trustee and the Certificate Administrator may rely upon and shall be protected in acting or refraining from acting upon any

it to be genuine and to have been signed or presented by the proper party or parties;

 

(ii)          
The Trustee and the Certificate Administrator may consult with counsel and the advice of such counsel or any Opinion of Counsel
shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder

(iii)          
Neither the Trustee nor the Certificate Administrator shall be under any obligation to exercise any of the trusts or powers vested
in it by this Agreement or the Certificates or to make any investigation of matters arising hereunder or to institute, conduct
or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders,
pursuant to the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee or the Certificate
Administrator, as applicable, reasonable security or indemnity satisfactory to it, against the costs, expenses and liabilities
which may be incurred therein or thereby; neither the Trustee nor the Certificate Administrator shall be required to expend or
risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or reasonable indemnity
satisfactory to it against such risk or liability is not reasonably assured to it; nothing contained herein shall, however, relieve
the Trustee of the obligation, upon the occurrence of a Servicer Termination Event which has not been cured, to exercise such
of the rights and powers vested in it by this Agreement, and to use the same degree of care and skill in their exercise as a prudent
man would exercise or use under the circumstances in the conduct of his own affairs;

 

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

 

(v)          
Prior to the occurrence of a Servicer Termination Event hereunder and after the curing of all Servicer Termination Events which
may have occurred, neither the Trustee nor the Certificate Administrator shall be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval,
bond or other paper or document, unless requested in writing to do so by Holders of Certificates entitled to more than 50% of
the Voting Rights; provided, however, that if the payment within a reasonable time to the Trustee or the Certificate
Administrator of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the
opinion of the Trustee or the Certificate Administrator, respectively, not reasonably assured to the Trustee or the Certificate
Administrator by the security afforded to it by the terms of this Agreement, the Trustee or the Certificate Administrator, respectively,
may require reasonable indemnity satisfactory to it from such requesting Holders against such expense or liability as a condition
to taking any such action. The reasonable expense of every such reasonable examination shall be paid by the requesting Holders;

 

(vi)         
The Trustee or the Certificate Administrator may execute any of the trusts or powers hereunder or perform any duties hereunder
either directly or by or through agents or attorneys; provided, however, that the appointment of such agents or
attorneys shall not relieve the Trustee or the Certificate Administrator of its duties or obligations hereunder; provided,
further, that the Trustee or the Certificate Administrator, as the case may be, may not perform any duties hereunder through
any Person that is a Prohibited Party;

 

    -418-

     

    

 

(vii)       
For all purposes under this Agreement, neither the Trustee nor the Certificate Administrator shall be deemed to have actual knowledge
or notice of any Servicer Termination Event or Asset Representations Reviewer Termination Event or any act, failure or breach
of any Person upon the occurrence of which the Trustee or the Certificate Administrator may be required to act unless a Responsible
Officer of the Trustee or the Certificate Administrator, as applicable, has actual knowledge thereof or unless written notice
of any event, act, failure or breach, as applicable, which is in fact such a default is received by the Trustee or the Certificate
Administrator at the respective Corporate Trust Office, and such notice references the Certificates or this Agreement;

 

(viii)       
Neither the Trustee nor the Certificate Administrator shall be responsible for any act or omission of the Master Servicer or the
Special Servicer (unless the Trustee is acting as Master Servicer or the Special Servicer, as the case may be, in which case the
Trustee shall only be responsible for its own actions as Master Servicer or the Special Servicer) or of the Depositor, the Operating
Advisor or the Asset Representations Reviewer;

 

(ix)          Neither the Trustee nor the Certificate Administrator shall in any way be liable by reason of any insufficiency in the Trust Fund
unless it is determined by a court of competent jurisdiction that the Trustee’s or Certificate Administrator’s, as
applicable, negligence or willful misconduct was the primary cause of such insufficiency;

 

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

 

(xi)           Except as otherwise expressly set forth in this Agreement, Wells Fargo Bank, National Association, acting in any particular capacity

be entitled to the same rights, indemnities, 

    -419-

Section 8.03       
Trustee and Certificate Administrator Not Liable for Validity or Sufficiency of Certificates, Mortgage Loans. The recitals
contained herein and in the Certificates, other than the acknowledgments of the Trustee or the Certificate Administrator in Sections 
2.02 and 2.04 and the signature, if any, of the Certificate Registrar and Authenticating Agent set forth on any outstanding
Certificate, shall be taken as the statements of the Depositor, the Master Servicer or the Special Servicer, as the case may be,
and the Trustee or the Certificate Administrator assume no responsibility for their correctness. Neither the Trustee nor the Certificate
Administrator makes any representations as to the validity or sufficiency of this Agreement (other than as to this Agreement being
a valid obligation of the Trustee and the Certificate Administrator) or of any Certificate (other than as to the signature, if
any, of the Trustee or the Certificate Administrator set forth thereon) or of any Mortgage Loan or related document. Neither the
Trustee nor the Certificate Administrator shall be accountable for the use or application by the Depositor of any of the Certificates
issued to it or of the proceeds of such Certificates, or for the use or application of any funds paid to the Depositor in respect
of the assignment of the Mortgage Loan to the Trust, or any funds deposited in or withdrawn from the Collection Account or any
other account by or on behalf of the Depositor, the Master Servicer, the Special Servicer or in the case of the Trustee, the Certificate
Administrator. The Trustee and the Certificate Administrator shall not be responsible for and may rely upon the accuracy or content

have if it were not Trustee or the Certificate Administrator.

 

Section 8.05       
Fees and Expenses of Trustee and Certificate Administrator; Indemnification of Trustee and Certificate Administrator.   (a)   As
compensation for the performance of its duties hereunder, the Trustee shall be paid its portion of the Certificate Administrator/Trustee
Fee, which shall cover recurring and otherwise reasonably anticipated expenses of the Trustee. As compensation for the performance
of its duties hereunder, the Certificate Administrator shall be paid its portion of the Certificate Administrator/Trustee Fee,
which shall cover recurring and otherwise reasonably anticipated expenses of the Certificate Administrator. The Certificate Administrator
shall pay the Trustee the Trustee’s portion of the Certificate Administrator/Trustee Fee. The Certificate Administrator/Trustee
Fee shall be paid monthly on a Mortgage Loan-by-Mortgage Loan basis. As to each Mortgage Loan and REO Loan (other than the portion
of an REO Loan related to any Companion Loan), the Certificate Administrator shall pay to the Trustee monthly the Trustee fee
from the Certificate Administrator/Trustee Fee, which Certificate Administrator/Trustee Fee shall accrue from time to time at
the Certificate Administrator/Trustee Fee Rate and the Certificate Administrator/Trustee Fee shall be computed on the basis of
the Stated Principal Balance of such

Mortgage
Loan, as applicable, and a 360-day year consisting of twelve 30-day months. The Certificate Administrator/Trustee Fee (which shall
not be limited to any provision of law in regard to the compensation of a trustee of an express trust) shall constitute the Trustee’s
and the Certificate Administrator’s sole form of compensation for all services rendered by them in the execution of the
trusts hereby created and in the exercise and performance of any of the powers and duties of the Trustee and Certificate Administrator
hereunder, except for the reimbursement of expenses specifically provided for herein. The Certificate Administrator/Trustee Fee
shall not be payable with respect to any Companion Loan.

 

(b)             The Trustee, the Certificate Administrator (in each case, including in its capacity as Custodian and in its individual capacity)
and any director, officer, employee, representative or agent of the Trustee and the Certificate Administrator, respectively, shall
be indemnified and held harmless by the Trust (to the extent of amounts on deposit in the Collection Account, the Lower-Tier
REMIC Distribution Account, as applicable, from time to time) against any loss, liability or expense (including, without limitation,
costs and expenses of litigation, and of enforcement of this indemnity, and of investigation, counsel fees, damages, judgments
and amounts paid in settlement, and expenses incurred in becoming the successor to the Master Servicer or the Special Servicer,
to the extent not otherwise paid hereunder) arising out of, or incurred in connection with, any act or omission of the Trustee
or the Certificate Administrator, respectively, relating to the exercise and performance of any of the powers, rights and duties
of the Trustee or the Certificate Administrator, respectively (including in any capacities in which they serve, such as paying
agent, REMIC Administrator, Authenticating Agent, Custodian, Certificate Registrar and 17g-5 Information Provider), hereunder;
provided, however, that none of the Trustee or the Certificate Administrator, nor any of the other above specified
Persons shall be entitled to indemnification pursuant to this Section 8.05(b) for (i) allocable overhead, (ii) expenses
or disbursements incurred or made by or on behalf of the Trustee or the Certificate Administrator, respectively, in the normal
course of the Trustee or the Certificate Administrator, respectively, performing its duties in accordance with any of the provisions
hereof, which are not “unanticipated expenses of the REMIC” within the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii),
(iii) any expense or liability specifically required to be borne thereby pursuant to the terms hereof or (iv) any loss,
liability or expense incurred by reason of willful misconduct, bad faith or negligence in the performance of the Trustee’s
or the Certificate Administrator’s, respectively, obligations and duties hereunder, or by reason of negligent disregard
of such obligations or duties, or as may arise from a breach of any representation or warranty of the Trustee specified in Section 8.12
or the Certificate Administrator specified in Section 8.14, respectively, made herein. The provisions of this
Section 8.05(b) shall survive the termination of this Agreement and any resignation or removal of the Trustee or the
Certificate Administrator, respectively, and appointment of a successor thereto. The foregoing indemnity shall also apply to the
Certificate Administrator in all of its capacities hereunder, including Custodian, Certificate Registrar and Authenticating Agent.

 

(c)             The Certificate Administrator shall indemnify and hold harmless the Depositor and Mortgage Loan Sellers from and against any claims,
losses, damages, penalties, fines, forfeitures, legal fees and expenses and related costs, judgments and other costs and expenses
incurred by the Depositor, any Mortgage Loan Seller or its Affiliates that arise out of or are based upon (i) a breach by
the Certificate Administrator, in its capacity as 17g-5 Information Provider or in any other capacity in which the Certificate
Administrator is required to make

 

    -421-

     

    

 

available
information to a Privileged Person that is an NRSRO, of its obligations under this Agreement or (ii) negligence, bad faith
or willful misconduct on the part of the Certificate Administrator, in its capacity as 17g-5 Information Provider or in any
other capacity in which the Certificate Administrator is required to make available information to a Privileged Person that is
an NRSRO, in the performance of such obligations or its negligent disregard of its obligations and duties under this Agreement.

 

Section 8.06       
Eligibility Requirements for Trustee and Certificate Administrator. Each of the Trustee and the Certificate Administrator
hereunder shall at all times be, and will be required to resign if it fails to be, (i) a corporation, national bank, national
banking association or a trust company, organized and doing business under the laws of any state or the United States of America,
authorized under such laws to exercise corporate trust powers and to accept the trust conferred under this Agreement, having a
combined capital and surplus of at least $100,000,000 and subject to supervision or examination by federal or state authority
and in the case of the Trustee, shall not be an Affiliate of the Master Servicer or the Special Servicer (except during any period
when the Trustee is acting as, or has become successor to, the Master Servicer or the Special Servicer, as the case may be, pursuant
to Section 7.02), (ii) an institution insured by the Federal Deposit Insurance Corporation, (iii) an institution
whose long-term senior unsecured debt is rated at least “BBB+” by S&P, “A-” by Fitch and, if rated
by KBRA, “A” by KBRA; provided that the Trustee shall not become ineligible
to serve based on a failure to satisfy such rating requirements as long as (a) it maintains a long-term unsecured debt rating
of no less than “BBB” by S&P and “A-“ by Fitch, (b) its short term debt obligations have a short term
rating of not less than “A-1” from S&P and “F1” by Fitch and (c) the Master Servicer maintains a long
term unsecured rating of at least “A” by S&P and “A+” by Fitch; provided that nothing in this
proviso shall impose on the Master Servicer any obligation to maintain such rating; provided, further, that if any
such institution is not rated by DBRS or KBRA, it maintains an equivalent (or higher) rating by any two other NRSROs (which may
include any of the Rating Agencies) or such other rating with respect to which the Rating Agencies have provided a Rating Agency
Confirmation and (iv) an entity that is not a Prohibited Party.

 

If
such corporation, national bank or national banking association publishes reports of condition at least annually, pursuant to
law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.06 the combined capital and surplus of such corporation, national bank or national banking association shall be deemed to be
its combined capital and surplus as set forth in its most recent report of condition so published. In the event the place of business
from which the Certificate Administrator administers the Trust REMICs or the Grantor Trust or in which the Trustee’s office
is located is in a state or local jurisdiction that imposes a tax on the Trust on the net income of a REMIC (other than a tax
corresponding to a tax imposed under the REMIC Provisions) or a grantor trust, the Certificate Administrator or the Trustee, as
applicable, shall elect either to (i) resign immediately in the manner and with the effect specified in Section 8.07,
(ii) pay such tax at no expense to the Trust or (iii) administer the Trust REMICs and/or the Grantor Trust, as applicable,
from a state and local jurisdiction that does not impose such a tax.

 

Section 8.07       
Resignation and Removal of the Trustee and Certificate Administrator. (a)  The
Trustee and the Certificate Administrator may at any time resign and be discharged from the trusts hereby created by giving written
notice thereof to the Depositor, the

 

    -422-

     

    

 

Master
Servicer, the Special Servicer and the Trustee or the Certificate Administrator, as applicable, the Operating Advisor, the Asset
Representations Reviewer, 17g-5 Information Provider and to all Certificateholders. The Certificate Administrator shall post
such notice to the Certificate Administrator’s Website in accordance with Section 3.13(b) and provide notice
of such event to the Master Servicer, the Special Servicer, the Depositor and the 17g-5 Information Provider, which shall
promptly post such notice to the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).
Upon receiving such notice of resignation, the Depositor shall use its reasonable best efforts to promptly appoint a successor
trustee or successor certificate administrator acceptable to the Master Servicer and, prior to the occurrence and continuance
of a Control Termination Event, the Directing Holder by written instrument, in duplicate, which instrument shall be delivered
to the resigning Trustee or Certificate Administrator and to the successor trustee or certificate administrator. A copy of such
instrument shall be delivered to the Master Servicer, the Special Servicer, the Certificateholders and the Trustee or Certificate
Administrator, as applicable, by the Depositor. The resigning Trustee or Certificate Administrator, as the case may be, shall
pay all costs and expenses associated with the transfer of its duties. If no successor trustee or certificate administrator shall
have been so appointed and have accepted appointment within thirty (30) days after the giving of such notice of resignation, the
resigning Trustee or Certificate Administrator may petition any court of competent jurisdiction for the appointment of a successor
trustee or certificate administrator, as applicable. The Trust shall pay all costs and expenses associated with such petition.

 

(b)             If at any time the Trustee or Certificate Administrator shall cease to be eligible in accordance with the provisions of Section 8.06
(and in the case of the Certificate Administrator, Section 5.08) and shall fail to resign after written request
therefor by the Depositor or the Master Servicer, or if at any time the Trustee or Certificate Administrator shall become incapable
of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or the Certificate Administrator or of its
property shall be appointed, or any public officer shall take charge or control of the Trustee or Certificate Administrator or
of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or if the Trustee or Certificate Administrator
(if different than the Trustee) shall fail (other than by reason of the failure of either the Master Servicer or the Special Servicer
to timely perform its obligations hereunder or as a result of other circumstances beyond the Trustee’s or Certificate Administrator’s,
as applicable, reasonable control) to timely publish any report to be delivered, published or otherwise made available by the
Certificate Administrator pursuant to Section 4.02 and such failure shall continue unremedied for a period of five
(5) days, or if the Certificate Administrator fails to make distributions required pursuant to Section 4.01 or Section 9.01,
then the Depositor may remove the Trustee or Certificate Administrator, as applicable, and appoint a successor trustee or certificate
administrator acceptable to the Master Servicer, by written instrument, in duplicate, which instrument shall be delivered to the
Trustee or Certificate Administrator so removed and to the successor trustee or certificate administrator in the case of the removal
of the Trustee or Certificate Administrator. A copy of such instrument shall be delivered to the Master Servicer, the Special
Servicer and the Certificateholders by the Depositor. Except as described in the following sentence, the terminated or removed
Trustee or Certificate Administrator, as applicable, shall bear all reasonable costs and expenses in connection with its termination
or removal. If no successor trustee or certificate administrator shall have been so appointed and have accepted appointment within
ninety (90) days after the giving of such notice of removal, the removed Trustee or Certificate Administrator may petition

 

    -423-

     

    

 

any
court of competent jurisdiction for the appointment of a successor trustee or certificate administrator, as applicable, at the
expense of the Trust.

 

(c)             The Holders of Certificates entitled to at least 50% of the Voting Rights may upon thirty (30) days’ prior written notice,
with or without cause, remove the Trustee or Certificate Administrator and appoint a successor trustee or certificate administrator
by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized,
one complete set of which instruments shall be delivered to the Master Servicer, one complete set to the Trustee or Certificate
Administrator so removed and one complete set to the successor so appointed. A copy of such instrument shall be delivered to the
Depositor, the Special Servicer and the remaining Certificateholders by the Master Servicer. In the event of any such termination
without cause pursuant to this Section 8.07(c), the successor trustee or certificate administrator, as applicable,
shall be responsible for all costs and expenses necessary to effect the transfer of responsibilities from its predecessor.

 

(d)             Any resignation or removal of the Trustee or Certificate Administrator and appointment of a successor trustee or certificate administrator
pursuant to any of the provisions of this Section 8.07 shall not become effective until (i) acceptance of appointment
by the successor trustee or certificate administrator as provided in Section 8.08 and (ii) the Certificate Administrator
shall have filed any required Form 8-K pursuant to Section 11.07 hereof and any other Form 8-K filings have been completed
with respect to any related Companion Loan. Further, the resigning Trustee or Certificate Administrator, as the case may be, shall
pay all costs and expenses associated with the transfer of its duties.

 

If
the same party is acting as Trustee and Certificate Administrator pursuant to this Agreement, any removal of either such party
in its capacity as Trustee or Certificate Administrator, as applicable, shall also result in such party’s removal in its
capacity as Trustee or Certificate Administrator, as applicable, and the Depositor shall appoint a successor certificate administrator
and a successor trustee, in each instance meeting the eligibility requirements set forth hereunder.

 

Upon
any succession of the Trustee or Certificate Administrator under this Agreement, the predecessor Trustee or Certificate Administrator
shall be entitled to the payment of accrued and unpaid compensation and reimbursement as provided for under this Agreement for
services rendered and expenses incurred (including without limitation, unreimbursed Advances). No Trustee or Certificate Administrator
shall be personally liable for any action or omission of any successor trustee or certificate administrator.

 

(e)             Upon the resignation, assignment, merger, consolidation, or transfer of the Trustee or its business to a successor, or upon the
termination of the Trustee, (a) the outgoing Trustee shall (i) endorse the original executed Mortgage Note for each
Mortgage Loan (to the extent that the original executed Mortgage Note for each Mortgage Loan was endorsed to the outgoing trustee),
without recourse, representation or warranty, express or implied, to the order of the successor, as trustee for the registered
Holders of CSAIL 2017-CX9 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2017-CX9 or in blank,
and (ii) in the case of the other assignable Mortgage Loan documents (to the extent such other Mortgage Loan documents were
assigned to the outgoing trustee), assign such Mortgage Loan

 

    -424-

     

    

 

documents
to such successor, and such successor shall review the documents delivered to it or to the Custodian with respect to each Mortgage
Loan, and certify in writing that, as to each Mortgage Loan then subject to this Agreement, such endorsement and assignment has
been made; (b) if any original executed Mortgage Note for a Mortgage Loan was not endorsed to the outgoing trustee, the Custodian
shall, upon its receipt of a Request for Release, deliver such Mortgage Note to the Depositor or the successor trustee, as requested,
and the Master Servicer and the Depositor shall cooperate with any successor trustee to ensure that such Mortgage Note is endorsed
(without recourse, representation or warranty, express or implied) to the order of the successor, as trustee for the registered
Holders of CSAIL 2017-CX9 Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series 2017-CX9 or in blank;
provided, however, that, notwithstanding anything to the contrary herein, to the extent any such endorsement of
such Mortgage Note requires the signature of the related Mortgage Loan Seller in order to comply with the foregoing, then the
Master Servicer shall use reasonable efforts to cause the related Mortgage Loan Seller to execute such endorsement; (c) if
any other assignable Mortgage Loan document was not assigned to the outgoing trustee, the Custodian shall, upon its receipt of
a Request for Release, deliver such Mortgage Loan document to the Depositor or the successor trustee, as requested, and the Master
Servicer and the Depositor shall cooperate with any successor trustee to ensure that such Mortgage Loan document is assigned to
such successor trustee; and (d) in any case, such successor trustee shall review the documents delivered to it or to the
Custodian with respect to each Mortgage Loan, and certify in writing that, as to each Mortgage Loan then subject to this Agreement,
such endorsements and assignments have been made or, in the event such endorsement or assignment cannot be made for any reason,
to note the same in such certification.

 

(f)             
Neither the Asset Representations Reviewer nor any of its Affiliates may be appointed as successor trustee or certificate administrator.

 

Section 8.08       
Successor Trustee or Certificate Administrator. (a)  Any
successor trustee or certificate administrator appointed as provided in Section 8.07 shall execute, acknowledge and
deliver to the Depositor, the Master Servicer, the Special Servicer and to its predecessor Trustee or Certificate Administrator
an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee or Certificate
Administrator shall become effective and such successor trustee or certificate administrator without any further act, deed or
conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as Trustee or Certificate Administrator herein. The predecessor Trustee shall deliver to the
successor trustee all Mortgage Files and related documents and statements held by it hereunder (other than any Mortgage Files
at the time held on its behalf by a Custodian, which Custodian, at Custodian’s option shall become the agent of the successor
trustee), and the Depositor, the Master Servicer, the Special Servicer and the predecessor Trustee shall execute and deliver such
instruments and do such other things as may reasonably be required to more fully and certainly vest and confirm in the successor
trustee all such rights, powers, duties and obligations, and to enable the successor trustee to perform its obligations hereunder.

 

(b)             No successor trustee or successor certificate administrator shall, as applicable, accept appointment as provided in this Section 8.08
unless at the time of such

 

    -425-

     

    

 

acceptance
such successor trustee or successor certificate administrator, as applicable, shall be eligible under the provisions of Section 8.06.

 

(c)             Upon acceptance of appointment by a successor trustee or successor certificate administrator as provided in this Section 8.08,
the Master Servicer shall deliver notice of the succession of such Trustee or Certificate Administrator, as applicable, to the
Depositor and the Certificateholders. If the Master Servicer fails to deliver such notice within ten (10) days after acceptance
of appointment by the successor trustee or successor certificate administrator, as applicable, such successor trustee or successor
certificate administrator shall cause such notice to be delivered at the expense of the Master Servicer.

 

Section 8.09       
Merger or Consolidation of Trustee or Certificate Administrator. Any Person into which the Trustee or the Certificate Administrator
may be merged or converted or with which it may be consolidated or any Person resulting from any merger, conversion or consolidation
to which the Trustee or the Certificate Administrator shall be a party, or any Person succeeding to all or substantially all of
the corporate trust business of the Trustee or the Certificate Administrator shall be the successor of the Trustee or the Certificate
Administrator, as applicable, hereunder; provided that, in the case of the Trustee, such successor person shall be eligible
under the provisions of Section 8.06, without the execution or filing of any paper or any further act on the part
of any of the parties hereto, anything herein to the contrary notwithstanding. The Certificate Administrator shall post such notice
to the Certificate Administrator’s Website in accordance with Section 3.13(b) and shall provide notice of such
event to the Master Servicer, the Special Servicer, the Depositor and the 17g-5 Information Provider, which shall post such
notice to the 17g-5 Information Provider’s Website in accordance with Section 3.13(c).

 

Section 8.10       
Appointment of Co-Trustee or Separate Trustee. (a)  Notwithstanding any other provisions hereof, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing
the same may at the time be located, the Master Servicer and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees,
jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such
Person or Persons, in such capacity, such title to the Trust, or any part thereof, and, subject to the other provisions of this
Section 8.10, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider
necessary or desirable. If the Master Servicer shall not have joined in such appointment within fifteen (15) days after the receipt
by it of a request to do so, or in case a Servicer Termination Event shall have occurred and be continuing, the Trustee alone
shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms
of eligibility as a successor trustee under Section 8.06 hereunder and no notice to Holders of Certificates of the
appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08. All co-trustee fees
shall be payable out of the Trust Fund.

 

(b)             In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 8.10, all rights,
powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed
by the Trustee and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction
in

 

    -426-

     

    

 

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

 

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

 

(d)             Any separate trustee or co-trustee may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full
power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf
and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by
law, without the appointment of a new or successor trustee.

 

(e)             The appointment of a co-trustee or separate trustee under this Section 8.10 shall not relieve the Trustee of its
duties and responsibilities hereunder.

 

Section 8.11       
Appointment of Custodians. The Certificate Administrator is hereby appointed as the Custodian to hold all or a portion
of the Mortgage Files. The Custodian shall be a depository institution subject to supervision by federal or state authority, shall
have combined capital and surplus of at least $15,000,000 and shall be qualified to do business in the jurisdiction in which it
holds any Mortgage File. The Custodian shall be subject to the same obligations and standard of care as would be imposed on the
Certificate Administrator hereunder in connection with the retention of Mortgage Files directly by the Certificate Administrator.
Upon termination or resignation of the Custodian, the Certificate Administrator may appoint another Custodian meeting the foregoing
requirements. The appointment of one or more Custodians by the Certificate Administrator shall not relieve the Certificate Administrator
from any of its obligations hereunder, and the Certificate Administrator shall remain responsible for all acts and omissions of
any Custodian. Any Custodian appointed hereunder must maintain a fidelity bond and errors and omissions policy in an amount customary
for Custodians which serve in such capacity in commercial mortgage loan securitization transactions, or may self-insure.

 

Section 8.12       
Representations and Warranties of the Trustee. The Trustee hereby represents and warrants to the Depositor, the Master
Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, each Serviced Companion Noteholder

bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforcement of creditors’ rights generally
and the rights of creditors of national banking associations specifically and (b) general principles of equity, regardless
of whether such enforcement is considered in a proceeding in equity or at law;

 

(v)          
The Trustee is not in violation of, and its execution and delivery of this Agreement and its performance and compliance with the
terms of this Agreement will not constitute a violation of, any law, any order or decree of any court or arbiter, or any order,
regulation or demand of any federal, state or local governmental or regulatory authority, which violation, in the Trustee’s
good faith and reasonable judgment, is likely to affect materially and adversely the ability of the Trustee to perform its obligations
under this Agreement;

 

(vi)          No litigation is pending or, to the best of the Trustee’s knowledge, threatened against the Trustee which would prohibit

and adversely affect the ability of the Trustee to perform its obligations under this Agreement;

 

(vii)        
No consent, approval, authorization or order of any court or governmental agency or body is required for the execution, delivery
and performance by the Trustee, or compliance by the Trustee with, this Agreement or the consummation of the transactions contemplated
by this Agreement, except for any consent, approval, authorization or order which has not been obtained or cannot be obtained
prior to the actual performance by the Trustee of its obligations under this Agreement, and which, if not obtained would not have

a
materially adverse effect on the ability of the Trustee to perform its obligations hereunder; and

 

(viii)        To its actual knowledge, the Trustee is not Risk Retention Affiliated with the Third Party Purchaser.

 

Section 8.13       
Provision of Information to Certificate Administrator, Master Servicer and Special Servicer. The Master Servicer shall
promptly, upon request, provide the Special Servicer and the Certificate Administrator with notice of any change in the identity
and/or contact information of any Serviced Companion Noteholder (to the extent it receives written notice of such change). The
Certificate Administrator, Master Servicer and Special Servicer may each conclusively rely on the information provided to them
regarding identity and/or contact information regarding any Serviced Companion Noteholder, and the Certificate Administrator,
Master Servicer and Special Servicer, as applicable, shall have no liability for notices not sent to the correct Serviced Companion
Noteholders or any obligation to determine the identity and/or contact information of the Serviced Companion Noteholders to the
extent updated or correct information regarding the holders of any of the Serviced Companion Noteholders or the most recent identity
and/or contact information regarding any of the Serviced Companion Noteholders has not been provided to the Certificate Administrator,
Master Servicer or Special Servicer, as applicable.

to the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, each Serviced

in the breach of, any material agreement or other instrument to which it is a party or which is applicable to it or any of its
assets;

 

(iii)           The Certificate Administrator has the full power and authority to enter into and consummate all transactions contemplated by this

with respect to such termination, unless the Master Servicer is the purchaser of such Mortgage Loans and (4) if a Mortgaged Property

and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class

of all the outstanding Certificates (other than the Class Z and Class R Certificates and the VRR Interest) and the payment or

    -431-

     

    

 

of
twenty-one (21) years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of
the United States to the Court of St. James’s, living on the date hereof.

 

Following
the date on which the Certificate Balances and Notional Amounts, as applicable, of the Class A-1, Class A-2, Class A-3, Class
A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class A-S, Class B, Class C and Class D Regular Interests have been reduced
to zero (and provided that there is only one Holder (or multiple Holders acting in unanimity) of the then-outstanding Certificates
(other than the Class Z and Class R Certificates and the VRR Interest)), the Sole Certificateholder shall have the right, with
the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and Class R Certificates and the
VRR Interest) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans and
each REO Property remaining in the Trust Fund as contemplated by clause (iii) of the first paragraph of this Section 9.01
by giving written notice to all the parties hereto no later than sixty (60) days prior to the anticipated date of exchange.
In the event that the Sole Certificateholder elects to exchange all of its Certificates (other than the Class Z and Class R Certificates)
and pay the Termination Purchase Amount) for all of the Mortgage Loans and the Trust’s portion of each REO Property remaining
in the Trust in accordance with the preceding sentence, such Sole Certificateholder, not later than the Distribution Date on which
the final distribution on the Certificates is to occur, shall (i) remit for deposit in the Collection Account an amount in
immediately available funds equal to (a) an amount equal to the product of (y) the VRR Retention Percentage and (z) the Termination
Purchase Amount to be paid to the Holders of the VRR Interest in exchange for the surrender of the VRR Interest, (b) an amount
equal to the product of (x) 1.00 minus the VRR Retention Percentage and (y) the Termination Purchase Amount to be paid to the
Trust, plus (z) all amounts due and owing to the Depositor, the Master Servicer, the Special Servicer, the Trustee and the Certificate
Administrator hereunder through the date of the liquidation of the Trust that may be withdrawn from the Collection Account, or
an escrow account acceptable to the respective parties hereto, pursuant to Section 3.05(a) or that may be withdrawn
from the Distribution Account pursuant to Section 3.05(a), but only to the extent that such amounts are not already
on deposit in the Collection Account, and (ii) be deemed to pay to the Trust (which amount shall be further deemed distributed
to the Holders of all outstanding Certificates) an amount equal to the Termination Purchase Amount. In addition, the Master Servicer
shall transfer all amounts required to be transferred to the Lower-Tier REMIC Distribution Account and Excess Interest Distribution
Account on the P&I Advance Date related to such Distribution Date in which the final distribution on the Certificates is to
occur from the Collection Account pursuant to the first paragraph of Section 3.04(b) (provided, however,
that if a Serviced Whole Loan is secured by REO Property, the portion of the above-described purchase price allocable to such
Trust’s portion of REO Property shall initially be deposited into the related REO Account). Upon confirmation that such
final deposits have been made and following the surrender of all its Certificates (other than the Class Z Certificates and Class
R Certificates) on the applicable Distribution Date, the Custodian shall, upon receipt of a Request for Release from the Master
Servicer, release or cause to be released to the Sole Certificateholder or any designee thereof, the Mortgage Files for the remaining
Mortgage Loans and shall execute all assignments, endorsements and other instruments furnished to it by the Sole Certificateholder
as shall be necessary to effectuate transfer of the Mortgage Loans and REO Properties remaining in the Trust Fund, and the Trust
shall be liquidated in accordance with Section 9.02. Solely for federal income tax purposes, the Sole Certificateholder
shall be deemed

 

    -432-

     

    

 

to
have purchased the assets of the Lower-Tier REMIC for an amount equal to the remaining Certificate Balance of the Principal
Balance Certificates, plus accrued, unpaid interest with respect thereto, and the Certificate Administrator shall credit such
amounts against amounts distributable in respect of such Certificates and Related Lower-Tier Regular Interests.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates,
in that order of priority, may, at their option, elect to purchase all of the Mortgage Loans (and all property acquired through
exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion of each REO Property remaining in
the Trust Fund as contemplated by clause (ii) of the first paragraph of this Section 9.01 by giving written
notice to the Trustee, the Certificate Administrator, and the other parties hereto no later than sixty (60) days prior to the
anticipated date of purchase; provided, however, that the Holders of the Controlling Class, the Special Servicer,
the Master Servicer, or the Holders of the Class R Certificates may so elect to purchase all of the Mortgage Loans and the Trust’s
portion of each REO Property remaining in the Trust Fund only on or after the first Distribution Date on which the aggregate Stated
Principal Balance of the Mortgage Loans and any REO Mortgage Loans held by the Trust is less than 1.0% of the aggregate Cut-off
Date Balance of the Mortgage Loans as set forth in the Preliminary Statement. This purchase shall terminate the Trust and retire
the then-outstanding Certificates.

 

In
the event that the Master Servicer or the Special Servicer purchases, or the Holders of the majority of the Controlling Class
or the Holders of the Class R Certificates purchase, all of the Mortgage Loans and the Trust’s portion of each REO Property
remaining in the Trust Fund in accordance with the preceding sentence, the Master Servicer, the Special Servicer, the Holders
of the majority of the Controlling Class or the Holders of the Class R
Certificates, as applicable, shall deposit in the Lower-Tier REMIC Distribution Account not later than the P&I Advance
Date relating to the Distribution Date on which the final distribution on the Certificates is to occur, an amount in immediately
available funds equal to the above-described purchase price (exclusive of any portion thereof payable to any Person other
than the Certificateholders pursuant to Section 3.05(a), which portion shall be deposited in the Collection Account).
In addition, the Master Servicer shall transfer to the Lower-Tier REMIC Distribution Account all amounts required to be transferred
thereto on such P&I Advance Date from the Collection Account pursuant to the first paragraph of Section 3.04(b),
together with any other amounts on deposit in the Collection Account that would otherwise be held for future distribution. Upon
confirmation that such final deposits and payments have been made, the Custodian shall release or cause to be released to the
Master Servicer, the Special Servicer, the Holders of the majority of the Controlling Class or the Holders of the Class R Certificates,
as applicable, the Mortgage Files for the remaining Mortgage Loans and shall execute all assignments, endorsements and other instruments
furnished to it by the Master Servicer, the Special Servicer, the Holders of the majority of the Controlling Class or the Holders
of the Class

 

    -433-

     

    

 

R
Certificates, as applicable, as shall be necessary to effectuate transfer of the Mortgage Loans and REO Properties remaining in
the Trust Fund.

 

For
purposes of this Section 9.01, the Holders of the majority of the Controlling Class shall have the first option to
terminate the Trust REMICs, then the Special Servicer, then the Master Servicer, and then the Holders of the Class R Certificates.
For purposes of this Section 9.01, the Directing Certificateholder with the consent of the Holders of the Controlling
Class, shall act on behalf of the Holders of the Controlling Class in purchasing the assets of the Trust and terminating the Trust.

 

Notice
of any termination pursuant to this Section 9.01 shall be given promptly by the Certificate Administrator by letter
to the Certificateholders, each Serviced Companion Noteholder and the 17g-5 Information Provider in accordance with the provisions
of Section 3.13(c) (who shall promptly post a copy of such additional notice on the 17g-5 Information Provider’s
Website in accordance with the provisions of Section 3.13(c)) and, if not previously notified pursuant to this Section 9.01,
to the other parties hereto mailed (a) in the event such notice is given in connection with the purchase of all of the Mortgage
Loans and each REO Property remaining in the Trust Fund, not earlier than the 15th day and not later than the 25th day of the
month next preceding the month of the final distribution on the Certificates, or (b) otherwise during the month of such final
distribution on or before the P&I Advance Determination Date in such month, in each case specifying (i) the Distribution
Date upon which the Trust will terminate and final payment of the Certificates will be made, (ii) the amount of any such
final payment and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being
made only upon presentation and surrender of the Certificates at the offices of the Certificate Registrar or such other location
therein designated.

 

After
transferring the Lower-Tier Distribution Amount and the amount of any Yield Maintenance Charges distributable to the Regular
Certificates pursuant to Section 4.01(c) to the Upper-Tier REMIC Distribution Account, in each case pursuant to
Section 3.04(b) and upon presentation and surrender of the Certificates by the Certificateholders on the final Distribution
Date, the Certificate Administrator shall distribute to each Certificateholder so presenting and surrendering its Certificates
(i) such Certificateholder’s Percentage Interest of that portion of the amounts then on deposit in the Upper-Tier
REMIC Distribution Account that are allocable to payments on the Class of Regular Certificates so presented, (ii) to Holders
of the Class V1-Z, Class V2-Z and Class Z Certificates so presented, any amounts remaining on deposit in the Excess Interest Distribution
Account, and (iii)  any remaining amount shall be distributed to the Class R Certificates in respect of the Class LR
Interest or the Class UR Interest, as applicable. Amounts transferred from Lower-Tier REMIC Distribution Account to the
Upper-Tier REMIC Distribution Account as of the final Distribution Date, shall be distributed in termination and liquidation
of the Lower-Tier Regular Interests and the Class LR Interest in accordance with Section 4.01(c). Any funds not distributed on such Distribution Date shall be set aside and held uninvested in trust for
the benefit of the Certificateholders not presenting and surrendering their Certificates in the aforesaid manner and shall be
disposed of in accordance with this Section 9.01 and Section 4.01(h).

 

Section 9.02       
Additional Termination Requirements. (a)  In the event the
Master Servicer or the Special Servicer purchases, or the Holders of the Controlling Class or the Holders

 

    -434-

     

    

 

of
the Class R Certificates purchase, all of the Mortgage Loans and the Trust’s portion of each REO Property remaining in the
Trust Fund as provided in Section 9.01, the Upper-Tier REMIC and Lower-Tier REMIC shall be terminated in accordance
with the following additional requirements, which meet the definition of a “qualified liquidation” in Section 860F(a)(4)
of the Code:

 

(i)            the Certificate Administrator shall specify the date of adoption of the plan of complete liquidation (which shall be the date

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

 

(ii)           during the 90-day liquidation period and at or prior to the time of the making of the final payment on the Certificates, the

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

ADDITIONAL REMIC PROVISIONS

 

Section 10.01   
REMIC Administration. (a)  The Certificate Administrator
shall make elections or cause elections to be made to treat each Trust REMIC as a REMIC under the Code and, if necessary, under
Applicable State and Local Tax Law. Each such election will be made on Form 1066 or other appropriate federal tax return
for the taxable year ending on the last day of the calendar year in which the Lower-Tier Regular Interests are issued. For the
purposes of the REMIC election in respect of the Upper-Tier REMIC, each Class of the Regular Interests shall be designated
as the “regular interests” and the Class UR Interest shall be designated as the sole class of “residual
interests” in the Upper-Tier REMIC. For purposes of the REMIC election in respect of the Lower-Tier REMIC, each
Class of Lower-Tier Regular Interests shall be designated as a class of “regular interests” and the Class LR
Interest shall be designated as the sole class of “residual interests” in the Lower-Tier REMIC. None of the Special
Servicer, the Master Servicer or the Trustee shall permit the creation of any “interests” (within the meaning of Section 860G
of the Code) in any Trust REMIC other than the foregoing interests.

 

(b)            The Closing Date is hereby designated as the “startup day” (the “Startup Day”) of each Trust REMIC within
the meaning of Section 860G(a)(9) of the Code.

 

    -435-

     

    

 

(c)          The
Certificate Administrator shall act on behalf of each Trust REMIC in relation to any tax matter or controversy involving either
such REMIC and shall represent each such REMIC in any administrative or judicial proceeding relating to an examination or audit
by any governmental taxing authority with respect thereto. The legal expenses, including without limitation attorneys’ or
accountants’ fees, and costs of any such proceeding and any liability resulting therefrom shall be expenses of the Trust
and the Certificate Administrator shall be entitled to reimbursement therefor out of amounts attributable to the Mortgage Loans
and any REO Properties on deposit in the Collection Account as provided by Section 3.05(a) unless such legal expenses and
costs are incurred by reason of the Certificate Administrator’s willful misconduct, bad faith or negligence. By their acceptance
thereof, the Holders of the largest Percentage Interest of the Class R Certificates shall be designated as the “tax matters
person”, in the manner provided under Treasury Regulations Section 1.860F-4(d) and Treasury Regulations Section 301.6231(a)(7)-1,
and the “partnership representative”, within the meaning of Section 6223 of the Code (to the extent such provision
is applicable to the Trust REMICs) of each Trust REMIC. By their acceptance thereof, the Holders of the largest Percentage Interest
of the Class R Certificates hereby agree to irrevocably appoint the Certificate Administrator as their agent to perform all of
the duties of the “tax matters person” and “partnership representative” for the Trust REMICs.

 

(d)          The
Certificate Administrator shall prepare or cause to be prepared and shall file, or cause to be filed, all of the Tax Returns that
it determines are required with respect to each Trust REMIC created hereunder, and shall cause the Trustee to sign (and the Trustee
shall timely sign) such Tax Returns in a timely manner. The ordinary expenses of preparing such returns shall be borne by the
Certificate Administrator without any right of reimbursement therefor.

 

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

 

(f)           The
Certificate Administrator shall take such actions and shall cause the Trust to take such actions as are reasonably within the
Certificate Administrator’s control and the scope of its duties more specifically set forth herein as shall be necessary
to maintain the status of each Trust REMIC as a REMIC under the REMIC Provisions and the Trustee shall assist the Certificate
Administrator to the extent reasonably requested by the Certificate Administrator to do so. Neither the Master Servicer nor the
Special Servicer shall knowingly or intentionally take any action, cause the Trust to take any action or fail to take (or fail
to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that,
under the REMIC Provisions, if taken or not taken, as the case may be, could (i) cause any Trust REMIC to fail to qualify as a
REMIC or (ii) result in the imposition of a tax upon any Trust REMIC or the Trust (including but not limited to the tax on “prohibited
transactions” as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in

 

    -436-

     

    

 

Section
860G(d) of the Code, but not including the tax on “net income from foreclosure property”) (either such event, an “Adverse
REMIC Event”) unless the Certificate Administrator receives an Opinion of Counsel (at the expense of the party seeking
to take such action or, if such party fails to pay such expense, and the Certificate Administrator determines that taking such
action is in the best interest of the Trust and the Certificateholders, at the expense of the Trust, but in no event at the expense
of the Certificate Administrator or the Trustee) to the effect that the contemplated action will not, with respect to the Trust,
any Trust REMIC created hereunder, endanger such status or, unless the Certificate Administrator determines in its sole discretion
to indemnify the Trust against such tax, result in the imposition of such a tax (not including a tax on “net income from
foreclosure property”). The Trustee shall not take or fail to take any action (whether or not authorized hereunder) as to
which the Certificate Administrator has advised it in writing that it has received an Opinion of Counsel to the effect that an
Adverse REMIC Event could occur with respect to such action. The Certificate Administrator may consult with counsel to make such
written advice, and the cost of same shall be borne by the party seeking to take the action not expressly permitted by this Agreement,
but in no event at the expense of the Certificate Administrator or the Trustee. At all times as may be required by the Code, the
Certificate Administrator will to the extent within its control and the scope of its duties more specifically set forth herein,
maintain substantially all of the assets of each Trust REMIC as “qualified mortgages” as defined in Section 860G(a)(3)
of the Code and “permitted investments” as defined in Section 860G(a)(5) of the Code.

 

(g)          In
the event that any applicable federal, state or local tax, including interest, penalties or assessments, additional amounts or
additions to tax, is imposed on any Trust REMIC, such tax shall be charged against amounts otherwise distributable to the Holders
of the Certificates, except as provided in the last sentence of this Section 10.01(g); provided that with respect
to the estimated amount of tax imposed on any “net income from foreclosure property” pursuant to Section 860G(c) of
the Code or any similar tax imposed by a state or local tax authority, the Special Servicer shall retain in the related REO Account
a reserve for the payment of such taxes in such amounts and at such times as it shall deem appropriate (or as advised by the Certificate
Administrator in writing), and shall remit to the Master Servicer such reserved amounts as the Master Servicer shall request in
order to pay such taxes. Except as provided in the preceding sentence, the Master Servicer shall withdraw from the Collection
Account sufficient funds to pay or provide for the payment of, and to actually pay, such tax as is estimated to be legally owed
by any Trust REMIC (but such authorization shall not prevent the Certificate Administrator from contesting, at the expense of
the Trust (other than as a consequence of a breach of its obligations under this Agreement), any such tax in appropriate proceedings,
and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The Certificate Administrator
is hereby authorized to and shall segregate, into a separate non-interest bearing account, the net income from any “prohibited
transaction” under Section 860F(a) of the Code or the amount of any taxable contribution to any Trust REMIC after the Startup
Day that is subject to tax under Section 860G(d) of the Code and use such income or amount, to the extent necessary, to pay such
prohibited transactions tax. To the extent that any such tax (other than any such tax paid in respect of “net income from
foreclosure property”) is paid to the Internal Revenue Service or applicable state or local tax authorities, the Certificate
Administrator shall retain an equal amount from future amounts otherwise distributable to the Holders of Class R Certificates
(as applicable) and shall distribute such retained amounts, (x) in the case of the Lower-Tier Regular Interests, to the Upper
Tier REMIC to the extent they are

 

    -437-

     

    

 

fully
reimbursed for any Realized Losses arising therefrom and then to the Holders of the Class R Certificates in respect of the Class
LR Interest in the manner specified in Section 4.01(c) and (z) in the case of the Upper-Tier REMIC, to the Holders of the
Principal Balance Certificates in the manner specified in Section 4.01(a) or Section 4.01(b), as applicable, to
the extent they are fully reimbursed for any Realized Losses arising therefrom and then to the Holders of the Class R Certificates
in respect of the Class UR Interest. None of the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer
shall be responsible for any taxes imposed on any Trust REMIC except to the extent such taxes arise as a consequence of a breach
of their respective obligations under this Agreement which breach constitutes willful misconduct, bad faith, or negligence by
such party.

 

(h)         The
Certificate Administrator shall, for federal income tax purposes, maintain or cause to be maintained books and records with respect
to each Trust REMIC on a calendar year and on an accrual basis or as otherwise may be required by the REMIC Provisions.

 

(i)           Following
the Startup Day, neither the Certificate Administrator nor the Trustee shall accept any contributions of assets to any Trust REMIC
unless the Certificate Administrator and the Trustee shall have received an Opinion of Counsel (at the expense of the party seeking
to make such contribution) to the effect that the inclusion of such assets in such Trust REMIC will not cause an Adverse REMIC
Event to occur.

 

(j)           Neither
the Certificate Administrator nor the Trustee shall enter into any arrangement by which the Trust or any Trust REMIC will receive
a fee or other compensation for services nor permit the Trust or any Trust REMIC to receive any income from assets other than
“qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined
in Section 860G(a)(5) of the Code.

 

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

 

(l)           None
of the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, as applicable, shall sell, dispose
of or substitute for any of the Mortgage Loans (except in connection with (i) the default, imminent default or foreclosure of
a Mortgage Loan, including but not limited to, the acquisition or sale of a Mortgaged Property acquired by foreclosure or deed
in lieu of foreclosure, (ii) the bankruptcy of the Trust, (iii) the termination of the Trust pursuant to Article IX of this Agreement
or (iv) a purchase of Mortgage Loans pursuant to Article II or Article III of this Agreement) or acquire any assets for
the Trust or any Trust REMIC or sell or dispose of any investments in the Collection Account or the REO Account for gain unless
it has received an Opinion of Counsel that such sale, disposition or substitution will not (a) affect adversely the status of
any Trust REMIC as a REMIC or (b) unless the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer,
as applicable, has determined in its sole discretion to indemnify the Trust against such tax, cause the Trust or any

 

    -438-

     

    

 

Trust REMIC
to be subject to a tax on “prohibited transactions” pursuant to the REMIC Provisions.

 

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

Article
XI

EXCHANGE ACT REPORTING AND REGULATION AB COMPLIANCE

 

Section
11.01     Intent of the Parties; Reasonableness. The parties hereto acknowledge and agree that the purpose of Article
XI of this Agreement is to facilitate compliance by the Depositor (and any Other Depositor of any Other Securitization
that includes a Serviced Companion Loan) with the provisions of Regulation AB and the related rules and regulations of the
Commission. The Depositor shall not exercise its rights to request delivery of information or other performance under these
provisions other than in reasonable good faith, or for purposes other than compliance with the Securities Act, the Exchange
Act, the Sarbanes-Oxley Act and, in each case, the rules and regulations of the Commission thereunder. The parties hereto
acknowledge that interpretations of the requirements of Regulation AB may

 

    -440-

     

    

 

change over time, due to interpretive guidance
provided by the Commission or its staff, and agree to comply with requests made by the Depositor (or any Other Depositor or
Other Trustee of any Other Securitization that includes a Serviced Companion Loan) in good faith for delivery of information
under these provisions on the basis of such evolving interpretations of Regulation AB (to the extent such interpretations
require compliance and are not “grandfathered”). In connection with the CSAIL 2017-CX9 Commercial Mortgage Trust,
Commercial Mortgage Pass-Through Certificates, Series 2017-CX9, and any Other Securitization subject to Regulation AB that
includes a Serviced Companion Loan, each of the Master Servicer, the Special Servicer, the Operating Advisor, the Trustee,
the Custodian and the Certificate Administrator shall cooperate fully with the Depositor and the Certificate Administrator,
and any Other Depositor, Other Trustee and Other Certificate Administrator of any Other Securitization that includes a
Serviced Companion Loan, as applicable, to deliver or make available to the Depositor or the Certificate Administrator, and
any such Other Depositor, Other Trustee or Other Certificate Administrator, as applicable (including any of its assignees or
designees), any and all statements, reports, certifications, records and any other information (in its possession or
reasonably attainable) necessary in the reasonable good faith determination of the Depositor or such Other Depositor, as
applicable, to permit the Depositor or such Other Depositor, as applicable, to comply with the provisions of Regulation AB,
together with such disclosures relating to the Master Servicer, the Special Servicer, the Operating Advisor, the Trustee, the
Custodian, the Asset Representations Reviewer and the Certificate Administrator, as applicable, and any Sub-Servicer, or
the servicing of the Mortgage Loans (and the related Serviced Companion Loan, if applicable), reasonably believed by the
Depositor or the related Other Depositor to be necessary in order to effect such compliance. Each party to this Agreement
shall have a reasonable period of time to comply with any written request made under this Section 11.01, but in any
event, shall, upon reasonable advance written request, provide information in sufficient time to allow the Depositor and each
Other Depositor to satisfy any related filing requirements. For purposes of this Article XI, to the extent any party
has an obligation to exercise commercially reasonable efforts to cause a third party to perform, such party hereunder shall
not be required to bring any legal action against such third party in connection with such obligation.

 

Section
11.02     Succession; Subcontractors. (a) As a condition to the succession to the Master Servicer and the Special
Servicer or to any Sub-Servicer (but only if such Sub-Servicer is a Servicing Function Participant and a servicer as
contemplated by Item 1108(a)(2)) as servicer or sub-servicer under this Agreement by any Person (i) into which the Master
Servicer and the Special Servicer or such Sub-Servicer may be merged or consolidated, or (ii) which may be appointed as a
successor to the Master Servicer and the Special Servicer or to any such Sub-Servicer, the person removing and replacing the
Master Servicer and the Special Servicer shall provide to the Depositor, the Certificate Administrator and each Other
Depositor, as applicable, at least fifteen (15) calendar days prior to the effective date of such succession or appointment
(or such shorter period as is agreed to by the Depositor), (x) written notice to the Depositor, the Other Depositor and the
Other Certificate Administrator of such succession or appointment and (y) in writing and in form and substance reasonably
satisfactory to the Depositor, all information relating to such successor reasonably requested by the Depositor, the Other
Depositor and the Other Certificate Administrator in order to comply with its reporting obligation under Item 6.02 of Form
8-K pursuant to the Exchange Act (if such reports under the Exchange Act are required to be filed under the Exchange Act); provided,

 

    -441-

     

    

 

however
that if disclosing such information prior to such effective date would violate any applicable law or confidentiality
agreement, the Master Servicer, the Special Servicer or any Additional Servicer, as the case may be, shall submit such
disclosure to the Depositor and the Other Depositor no later than the first Business Day after the effective date of such
succession or appointment.

 

(b)         Each
of the Master Servicer, the Special Servicer, the Sub-Servicer, the Trustee, the Operating Advisor (subject to Section 3.26(p)),
the Asset Representations Reviewer and the Certificate Administrator (each of the Master Servicer, the Special Servicer, the Trustee,
the Operating Advisor, the Asset Representations Reviewer and the Certificate Administrator and each Sub-Servicer, for purposes
of this Section 11.02, a “Servicer”) is permitted to utilize one or more Subcontractors to perform certain
of its obligations hereunder. If such Subcontractor will be a Servicing Function Participant, such Servicer shall promptly upon
written request provide to the Depositor or any Mortgage Loan Seller (and any Other Trustee, Other Certificate Administrator and
Other Depositor related to any Other Securitization that includes a related Serviced Companion Loan) a written description (in
form and substance satisfactory to the Depositor, such Mortgage Loan Seller or such Other Trustee, Other Certificate Administrator
or Other Depositor, as applicable) of the role and function of each Subcontractor utilized by such Servicer, specifying (i) the
identity of such Subcontractor and (ii) the elements of the Servicing Criteria that will be addressed in assessments of compliance
provided by each such Subcontractor. As a condition to the utilization by such Servicer of any Subcontractor determined to be
a Servicing Function Participant, such Servicer shall (i) with respect to any such Subcontractor engaged by such Servicer that
is an Initial Sub-Servicer, use commercially reasonable efforts to cause, and (ii) with respect to any other subcontractor with
which it has entered into a servicing relationship, cause such Subcontractor used by such Servicer for the benefit of the Depositor
and the Trustee (and any Other Trustee, Other Certificate Administrator and Other Depositor related to any Other Securitization
that includes a related Serviced Companion Loan) to comply with the provisions of Section 11.10 and Section 11.11
of this Agreement to the same extent as if such Subcontractor were such Servicer. With respect to any Servicing Function Participant
engaged by such Servicer that is an Initial Sub-Servicer, such Servicer shall be responsible for using commercially reasonable
efforts to obtain, and with respect to each other Servicing Function Participant engaged by such Servicer, such Servicer shall
obtain from each such Servicing Function Participant and deliver to the applicable Persons any assessment of compliance report
and related accountant’s attestation required to be delivered by such Subcontractor under Section 11.10 and Section
11.11, in each case, as and when required to be delivered. For the avoidance of doubt, the Custodian shall not be permitted
to utilize any Subcontractor to perform any of its obligations hereunder.

 

(c)       
 Notwithstanding the foregoing, if a Servicer engages a Subcontractor, other than an Initial Sub-Servicer in
connection with the performance of any of its duties under this Agreement, such Servicer shall be responsible for determining
whether such Subcontractor is a “servicer” within the meaning of Item 1101 of Regulation AB and whether any such
Subcontractor meets the criteria in Item 1108(a)(2)(i), (ii) or (iii) of Regulation AB. If a Servicer determines, pursuant to
the preceding sentence, that such Subcontractor is a “servicer” within the meaning of Item 1101 of Regulation AB
and meets the criteria in Item 1108(a)(2)(i), (ii) or (iii) of Regulation AB, then such Subcontractor shall be deemed to be a
Sub-Servicer for purposes of this Agreement, the engagement of such Sub-Servicer shall not be effective unless and until

 

    -442-

     

    

 

notice is given to the Depositor and the Certificate Administrator of any such Sub-Servicer and Sub-Servicing Agreement.
Other than with respect to the Initial Sub-Servicer, no Sub-Servicing Agreement shall be effective until fifteen (15) days
after such written notice is received by the Depositor and the Certificate Administrator (or such shorter period as is agreed
to by the Depositor). Such notice shall contain all information reasonably necessary to enable the Certificate Administrator
to accurately and timely report the event under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports under the
Exchange Act are required to be filed under the Exchange Act).

 

(d)         In
connection with the succession to the Trustee under this Agreement by any Person (i) into which the Trustee may be merged or consolidated,
or (ii) which may be appointed as a successor to the Trustee, the Trustee shall deliver written notice to the Depositor, the Certificate
Administrator and the 17g-5 Information Provider, which shall promptly post such notice to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c), in each case at least thirty (30) calendar days prior to the effective date of such
succession or appointment (or if such prior notice is violative of applicable law or any applicable confidentiality agreement,
no later than one (1) Business Day after such effective date of succession) and shall furnish to the Depositor and the Certificate
Administrator, in writing and in form and substance reasonably satisfactory to the Depositor and the Certificate Administrator,
all information reasonably necessary for the Certificate Administrator to accurately and timely report, pursuant to Section
11.07, the event under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports under the Exchange Act are required
to be filed under the Exchange Act).

 

(e)         Notwithstanding
anything to the contrary contained in this Article XI, in connection with any Sub-Servicer and/or any Mortgage Loan that
is the subject of an Initial Sub-Servicing Agreement, with respect to all matters related to Regulation AB, the Master Servicer
shall not have any obligation other than to use commercially reasonable efforts to cause such Sub-Servicer to comply with its
obligations under such Initial Sub-Servicing Agreement.

 

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

 

Section
11.03     Filing Obligations. (a) The Master Servicer, the Special Servicer, the Certificate Administrator, the Operating
Advisor, the Asset Representations Reviewer and the Trustee shall reasonably cooperate with the Depositor in connection with the
satisfaction of the Trust’s reporting requirements under the Exchange Act. Pursuant to Sections 11.04, 11.05,
11.06 and 11.07 of this Agreement, the Certificate Administrator shall prepare for execution by the Depositor any
Forms 8-K, 10-D, ABS-EE and 10-K required by the Exchange Act, in order to permit the timely filing thereof, and the Certificate
Administrator shall file (via the Commission’s Electronic Data Gathering, Analysis and Retrieval (“EDGAR”)
system) such Forms executed by the Depositor.

 

Each
party hereto shall be entitled to rely on the information in the Prospectus or this Agreement with respect to the identity of
any “sponsor”, credit enhancer, derivative provider

 

    -443-

     

    

 

or “significant obligor” as of the Closing Date other
than with respect to itself or any information required to be provided by it or indemnified for by it pursuant to any separate
agreement.

 

(b)         In
the event that the Certificate Administrator is unable to timely file with the Commission all or any required portion of any Form
8-K, 10-D, ABS-EE or 10-K required to be filed by this Agreement because required disclosure information was either not delivered
to it or delivered to it after the delivery deadlines set forth in this Agreement, the Certificate Administrator will promptly
notify the Depositor. In the case of Forms 10-D, ABS-EE and 10-K, the Depositor, the Master Servicer, the Certificate Administrator,
the Operating Advisor and the Trustee will thereupon cooperate to prepare and file a Form 12b-25 and a Form 10-D/A, Form ABS-EE/A
or Form 10-K/A, as applicable, pursuant to Rule 12b-25 of the Exchange Act. In the case of Form 8-K, the Certificate Administrator
will, upon receipt of all required Form 8-K Disclosure Information and upon the approval and direction of the Depositor, include
such disclosure information on the next succeeding Form 10-D to be filed for the Trust. In the event that any previously filed
Form 8-K, Form 10-D, Form ABS-EE or Form 10-K needs to be amended, the Certificate Administrator will notify the Depositor, and
such other parties as needed and the parties hereto will cooperate with the Certificate Administrator to prepare any necessary
Form 8-K/A, Form 10-D/A, Form ABS-EE/A or Form 10-K/A. Any Form 15, Form 12b-25 or any amendment to Form 8-K, Form 10-D, Form
ABS-EE or Form 10-K shall be signed by an officer of the Depositor. The parties to this Agreement acknowledge that the performance
by the Certificate Administrator of its duties under this Section 11.03 related to the timely preparation and filing of
Form 15, a Form 12b-25 or any amendment to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K is contingent upon the parties observing
all applicable deadlines in the performance of their duties under Sections 11.03, 11.04, 11.05, 11.06,
11.07, 11.08, 11.09, 11.10 and 11.11 of this Agreement. The Certificate Administrator shall
have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare, arrange
for execution and/or timely file any such Form 15, Form 12b-25 or any amendments to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K,
where such failure results from the Certificate Administrator’s inability or failure to receive, on a timely basis, any
information from any other party hereto needed to prepare, arrange for execution or file such Form 15, Form 12b-25 or any amendments
to Form 8-K, Form 10-D, Form ABS-EE or Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

permitted extensions under the Exchange Act), the Certificate Administrator shall prepare and file on behalf of the Trust any

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

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 11.05. Neither the Trustee nor the Certificate Administrator shall
have any liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare, arrange
for execution and/or timely file such Form 10-K, where such failure results from the Certificate Administrator’s failure
to receive, on a timely basis, any information from the parties to this Agreement (or any Sub-Servicer or Servicing Function Participant
engaged by any such parties) needed to prepare, arrange for execution or file such Form 10-K, not resulting from its own negligence,
bad faith or willful misconduct.

 

(c)     
    Upon written request from any Mortgage Loan Seller, Other Depositor, the Master Servicer or the
Special Servicer, the Certificate Administrator shall confirm to such Mortgage Loan Seller, Other Depositor, Master Servicer

Companion Loan or a party that services, specially services or is trustee or custodian for a Serviced Companion Loan) in the same
time frame as set forth in this Section 11.05.

 

Section
11.06     Sarbanes-Oxley Certification. Each Form 10-K shall include a Sarbanes-Oxley Certification
in the form attached as Exhibit Y required to be included therewith pursuant to the Sarbanes-Oxley Act. For so long as

the Special Servicer, the Trustee, the Certificate Administrator, the Custodian, the Asset Representations Reviewer (in the case
of the Asset Representations Reviewer, solely with respect to reporting periods in which the Asset Representations Reviewer is
required to deliver an Asset Review Report Summary) and the Operating Advisor shall provide, and (i) with respect to each Initial
Sub-Servicer engaged by the Master Servicer or the Special Servicer, as applicable, that is a Servicing Function Participant use

Function Participant to provide, to the Person who signs the Sarbanes-Oxley Certification for the Trust or any Other Securitization
that includes a Serviced Companion Loan (individually and collectively, the “Certifying Person”), on or before

Z-3, Z-4, Z-5, Z-6 or Z-7 (each, a “Performance Certification”), as applicable,

Parties”)
can reasonably rely. In addition, in the event that any Companion Loan (other than a Non-Serviced Companion Loan) is deposited
into this trust and deposited into a commercial mortgage securitization (an “Other Securitization”) and the
Reporting Servicer is provided with timely and complete contact information for the parties to the other securitizations, each
Reporting Servicer, upon not less than thirty (30) days prior written request, shall provide to the Person who signs the Sarbanes-Oxley
Certification with respect to such Other Securitization a certification in form and substance similar to applicable Performance
Certification (which shall address the matters contained in the applicable Performance Certification, but solely with respect
to the related Companion Loan) on which Person, the entity for which the Person acts as an officer (if the Person is an individual),
and such entity’s officers, directors and Affiliates can reasonably rely. With respect to any Non-Serviced Companion Loan,
the Certificate Administrator will use its reasonable efforts to procure a Sarbanes-Oxley Certification from the applicable Non-Serviced
Master Servicer, Non-Serviced Special Servicer and Non-Serviced Trustee in form and substance similar to a Performance Certification.

certifications being delivered by such Reporting Servicer) to enable the Certification Parties to rely upon each (i) annual compliance
statement provided pursuant to Section 11.09, if applicable, (ii) annual report on assessment of compliance with servicing
criteria provided pursuant to Section 11.10 and (iii) accountant’s report provided pursuant to Section 11.11,
and shall include a certification that each such annual compliance statement or report discloses any deficiencies or defaults
described to the registered public accountants of such Reporting Servicer to enable such accountants to render the certificates
provided for in Section 11.11. In the event any Reporting Servicer is terminated or resigns pursuant to the terms of this
Agreement, or any applicable sub-servicing agreement or primary servicing agreement, as the case may be, such Reporting Servicer
shall provide a certification to the Certifying Person pursuant to this Section 11.06 with respect to the period of time
it was subject to this Agreement or the applicable sub-servicing or primary servicing agreement, as the case may be. Each such
Performance Certification shall be provided in EDGAR-Compatible Format, or in such other format agreed upon by the Depositor,
the Certificate Administrator, any affected Other Depositor and Other Certificate Administration and such providing parties. Notwithstanding
the foregoing, nothing in this Section 11.06 shall require any Reporting Servicer (i) to certify or verify the accurateness
or completeness of any information provided to such Reporting Servicer by third parties (including a Significant Obligor, but
other than an Additional Servicer or a Sub-Servicer appointed pursuant to Section 3.20), (ii) to certify information other
than to such Reporting Servicer’s knowledge and in accordance with such Reporting Servicer’s responsibilities hereunder

face.

 

Notwithstanding
anything to the contrary contained in this Section 11.06, with respect to each year in which the Trust and the trust for
each Other Securitization is not subject to the reporting requirements of the Exchange Act, none of the parties required to deliver
any certification under this Section 11.06 shall be obligated to do so.

Section
11.16     Certain Matters Relating to the Future Securitization of the Serviced Pari Passu Companion Loans. (a) Each of
the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer shall, and the Master Servicer and
the Special Servicer shall use commercially reasonable efforts to cause any sub-servicer appointed with respect to any
Serviced Pari Passu Companion Loan to, upon written request or notice from a Mortgage Loan Seller (or a permitted transferee
of such Mortgage Loan Seller pursuant to the related Intercreditor Agreement), reasonably cooperate with the Mortgage Loan
Seller (or such permitted transferee) selling any Serviced Pari Passu Companion Loan into a securitization that is required
to comply with Regulation AB (a “Regulation AB Companion Loan Securitization”) and, to the extent needed
in order to comply with Regulation AB, provide to the Mortgage Loan Seller (or such permitted transferee) information about
itself that such Mortgage Loan Seller reasonably requires to meet the requirements of Items 1117 and 1119 and paragraphs (b),
(c)(3), (c)(4) and (c)(5) of Item 1108 of Regulation AB and shall reasonably cooperate with such Mortgage Loan Seller to
provide such other information as may be reasonably necessary to comply with the requirements of Regulation AB. Each of the
Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer understands that such information may be
included in the offering material related to a Regulation AB Companion Loan Securitization and agrees to negotiate in good
faith an agreement (subject to the final sentence of this sub-section) to indemnify and hold the related depositor and
underwriters involved in the offering of the related Certificates harmless for any costs, liabilities, fees and expenses
incurred by the depositor or such underwriters as a result of any material misstatements or omissions or

 

    -463-

     

    

 

alleged material
misstatements or omissions in any such offering material to the extent that such material misstatement or omission was made
in reliance upon any such information provided by the Trustee (where such information pertains to the Trustee individually
and not to any specific aspect of the Trustee’s duties or obligations under this Agreement), the
Certificate Administrator (where such information pertains to the Certificate Administrator individually and not to any
specific aspect of the Certificate Administrator’s duties or obligations under this Agreement), the Master Servicer
(where such information pertains to the Master Servicer individually and not to any specific aspect of the Master
Servicer’s duties or obligations under this Agreement) and the Special Servicer (where such information pertains to the
Special Servicer individually and not to any specific aspect of the Special Servicer’s duties or obligations under this
Agreement), as applicable, to such depositor, underwriters or Mortgage Loan Seller (or permitted transferee) as required by
this clause (a). Notwithstanding the foregoing, to the extent that the information provided by the Trustee, the Certificate
Administrator, the Master Servicer or the Special Servicer, as applicable, for inclusion in the offering materials related to
such Regulation AB Companion Loan Securitization is substantially and materially similar to the information provided by such
party with respect to the offering materials related to this transaction, subject to any required changes due to any
amendments to Regulation AB or any changes in the interpretation of Regulation AB, such party shall be deemed to be in
compliance with this Section 11.16(a). Any indemnification agreement executed by the Trustee, the Certificate
Administrator, the Master Servicer or the Special Servicer in connection with the Regulation AB Companion Loan Securitization
shall be substantially similar to the related indemnification agreement executed in connection with this Agreement. It shall
be a condition precedent to any party’s obligations otherwise set forth above that the applicable Mortgage Loan Seller
(or permitted transferee) shall have (a) provided reasonable advance notice (and, in any event, not less than ten (10)
Business Days) of the exercise of its rights hereunder and (b) paid, or entered into reasonable agreement to cause to be
paid, the reasonable out-of-pocket expenses (including reasonable fees and expenses of counsel) incurred by such party

the Special Servicer shall use commercially reasonable efforts to cause any Servicing Function Participant appointed with respect

at the closing of such Regulation AB Companion Loan Securitization instead of each time a filing is required), cooperate with
the depositor, trustee, certificate administrator, master servicer or special servicer for any Regulation AB Companion Loan Securitization
in preparing each Form 10-D, Form ABS-EE and Form 10-K required to be filed by such Regulation AB Companion Loan Securitization
(until January 30 of the first year in which the trustee or other applicable party for such Regulation AB Companion Loan Securitization
files a Form 15 Suspension Notification with respect to the related trust) and shall provide to such depositor, trustee, certificate
administrator or master servicer within the time period set forth in the Other Pooling and Servicing Agreement (so long as such
time period is no earlier than the time periods set forth herein) for such Regulation AB Companion Loan Securitization such information
relating to a Serviced Securitized Companion Loan as may be reasonably necessary for the depositor, trustee, certificate administrator
and master servicer of the Regulation AB Companion Loan Securitization to comply with the reporting requirements of Regulation
AB and the Exchange Act; provided, however, that any parties to any Regulation AB

shall consult with any sub-servicer appointed with respect to the related Serviced Whole Loan), and the Trustee, the Certificate
Administrator, such Master Servicer and the Special Servicer shall cooperate with such parties in respect of establishing the

AB Companion Loan Securitization instead of each time a filing is required), provide the trustee or certificate
administrator, as applicable, under a Regulation AB Companion Loan Securitization (until January 30 of the first year in

Form 15 Suspension Notification with respect to the related trust) information with respect to any event that is required to
be disclosed under Form 8-K with respect to a Serviced Securitized Companion Loan within two Business Days after the
occurrence of such event of which it has knowledge. Notwithstanding the foregoing, to the extent the Trustee, the Certificate

timing, reporting and attestation requirements imposed on such party in ARTICLE XI of this Agreement (other than this Section
11.16) with respect to the comparable timing, reporting and attestation requirements contemplated in this Section
11.16(c) with respect to such Regulation AB Companion Loan Securitization, such party shall be deemed to be in compliance
with the provisions of this Section 11.16(c).

 

(d)         On
or before March 1 of each year (or February 29 if a leap year) during which a Regulation AB Companion Loan Securitization is required
to file an annual report on Form 10-K (and not in respect of any year in which Regulation AB Companion Loan Securitization is
not required to file an annual report on Form 10-K because a Form 15 Suspension Notification with respect to the related trust
was filed), each of the Trustee, the Master Servicer and the Special Servicer shall, and the Master Servicer and the Special Servicer
shall use commercially reasonable efforts to cause any Servicing Function Participant appointed with respect to a Serviced Securitized
Companion Loan to, upon request or notice from such trustee or certificate administrator (which request or notice may be given
once at the closing of such Regulation AB Companion Loan Securitization instead of each time a filing is required), provide, with

material respects with the timing, reporting and attestation requirements imposed on such party in ARTICLE XI of this Agreement
(other than this Section 11.16) with respect to the comparable timing, reporting and attestation requirements contemplated

report on Form 10-K because a Form 15 Suspension Notification with respect to the related trust was filed), each of the Trustee,
the Certificate Administrator, the Master Servicer and the Special Servicer shall, and the Master Servicer and the Special Servicer
shall use commercially reasonable efforts to cause any Servicing Function Participant appointed with respect to a Serviced Securitized
Companion Loan to, to the extent required pursuant to Item 1123 of Regulation AB, deliver, with respect to itself, to the trustee
or certificate administrator under the such Regulation AB Companion Loan Securitization, upon request or notice from such trustee
(which request or notice may be given once at the closing of such Regulation AB Companion Loan Securitization instead of each
time a filing is required), under such Regulation AB Companion Loan Securitization a servicer compliance statement signed by an
authorized officer of such Person that satisfies the requirements of Item 1123 of Regulation AB. Notwithstanding the foregoing,
to the extent the Trustee, the Certificate Administrator, the Master Servicer or the Special Servicer, as the case may be, complies
in all material respects with the timing, reporting and attestation requirements imposed on such party in ARTICLE XI of
this Agreement (other than this Section 11.16) with respect to the comparable timing, reporting and attestation requirements
contemplated in this Section 11.16(e) with respect to such Regulation AB Companion Loan Securitization, such party shall
be deemed to be in compliance with the provisions of this Section 11.16(e).

 

(f)       Each
of the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer shall use commercially reasonable
efforts to cause a Servicing Function Participant to agree (severally but not jointly) to indemnify (such indemnity limited to
each such parties respective failure described below) and hold the related Mortgage Loan Seller (or permitted transferee), depositor,
sponsor(s), trustee, certificate administrator or master servicer under a Regulation AB Companion Loan Securitization harmless
for any costs, liabilities, fees and expenses incurred by such Mortgage Loan Seller, depositor, sponsor(s), trustee, certificate
administrator or master servicer as a result of any failure by the Servicing Function Participant to comply with the reporting
requirements to the extent applicable set forth under Sections 11.16(b), (c), (d) or (e) above.

 

Any
subservicing agreement related to a Serviced Securitized Companion Loan shall contain a provision requiring the related Sub-Servicer
to provide to the Master Servicer or Special Servicer, as applicable, information, reports, statements and certificates with respect
to

 

    -466-

     

    

 

itself and such Serviced Securitized Companion Loan comparable to any information, reports, statements or certificates required
to be provided by the Master Servicer or Special Servicer pursuant to this Section 11.16, even if such Sub-Servicer is
not otherwise required to provide such information, reports or certificates to any Person in order to comply with Regulation AB.
Such information, reports or certificates shall be provided to the Master Servicer or Special Servicer, as applicable, no later
than two Business Days prior to the date on which the Master Servicer or Special Servicer, as applicable, is required to deliver
its comparable information, reports, statements or certificates pursuant to this Section 11.16.

 

(g)         With
respect to any Mortgaged Property that secures a Serviced Companion Loan that the applicable Other Depositor has notified the
Master Servicer and the Special Servicer in writing is a “significant obligor” (within the meaning of Item 1101(k)
of Regulation AB) (together with notification of the Relevant Distribution Date) with respect to an Other Securitization that
includes such Serviced Companion Loan, to the extent that the Master Servicer is in receipt of the updated financial statements
of such “significant obligor” for any calendar quarter (other than the fourth calendar quarter of any calendar year)
from the Mortgagor or Special Servicer, beginning with the first calendar quarter following receipt of such notice from the Other
Depositor, or the updated financial statements of such “significant obligor” for any calendar year, beginning for
the calendar year following such notice from the Other Depositor, as applicable, the Master Servicer shall deliver to the Other
Depositor, on or prior to the day that occurs two (2) Business Days prior to the related “significant obligor” NOI
Quarterly Filing Deadline or seven (7) Business Days prior to the related Significant Obligor NOI Yearly Filing Deadline, as applicable,
(A) if such financial statement receipt occurs twelve (12) or more Business Days prior to the related Significant Obligor NOI
Quarterly Filing Deadline or seventeen (17) or more Business Days prior to the related Significant Obligor NOI Yearly Filing Deadline,
as applicable, such financial statements of the “significant obligor”, together with the net operating income of such
“significant obligor” for the applicable period as calculated by the Master Servicer in accordance with CREFC®
guidelines and (B) if such financial statement receipt occurs less than twelve (12) Business Day prior to the related Significant
Obligor NOI Quarterly Filing Deadline or less than seventeen (17) Business Days prior to the related Significant Obligor NOI Yearly
Filing Deadline, as applicable, such financial statements of the “significant obligor”, together with the net operating
income of such “significant obligor” for the applicable period as reported by the related Mortgagor in such financial
statements.

 

If
the Master Servicer does not receive such financial information of any such “significant obligor” (identified to it
as such by the Other Depositor in accordance with the preceding paragraph) within ten (10) Business Days after the date such financial
information is required to be delivered under the related Mortgage Loan documents, the Master Servicer shall notify the Other
Depositor with respect to such Other Securitization that includes the related Serviced Pari Passu Companion Loan (and shall cause
any related Sub-Servicing Agreement entered into after receipt of written notice from the Other Depositor that such Serviced Pari
Passu Companion Loan is a significant obligor to require the related Sub-Servicer to notify such Other Depositor) that it has
not received them. The Master Servicer shall use efforts consistent with the Servicing Standard (taking into account, in addition,
the ongoing reporting obligations of such Other Depositor under the Exchange Act) to obtain the periodic financial statements
required to be delivered by the related Mortgagor under the related Mortgage Loan documents.

 

    -467-

     

    

 

The
Master Servicer shall (and shall cause any related Sub-Servicing Agreement entered into after receipt of written notice from the
Other Depositor that such Serviced Pari Passu Companion Loan is a significant obligor to require the related Sub-Servicer to)
retain written evidence of each instance in which it (or a Sub-Servicer) attempts to contact the related Mortgagor related to
any such “significant obligor” (identified to it as such by the Other Depositor in accordance with the second preceding
paragraph) to obtain the required financial information and is unsuccessful and, within five (5) Business Days prior to the date
in which a Form 10-D or Form 10-K, as applicable, is required to be filed by the Other Securitization, shall forward an Officer’s
Certificate evidencing its attempts to obtain this information to the certificate administrator and Other Depositor related to
such Other Securitization. This Officer’s Certificate should be addressed to the certificate administrator at its corporate
trust office, as specified in the related Other Pooling and Servicing Agreement.

Termination Event pursuant to clause (x) of the definition thereof prior to the expiration of the grace period applicable to
such party’s obligations under this Article XI as provided for in such clause (x) nor shall any such party be

Section
12.01     Asset Review.

 

(a)       On or prior to each Distribution Date, based on
either the CREFC® Delinquent Mortgage Loan Status Report or the CREFC® Loan Periodic Update
File, the Certificate Administrator shall determine if an Asset Review Trigger has occurred. If an Asset Review Trigger is
determined to have occurred, the Certificate Administrator shall promptly provide written notice to the Asset Representations
Reviewer and to all Certificateholders and each other party to this Agreement. Any notice required to be delivered to the
Certificateholders pursuant to this Section 12.01 shall be delivered by the Certificate Administrator by posting such
notice on the Certificate Administrator’s Website, by mailing to their addresses appearing in the

 

    -468-

     

    

 

Certificate
Register and by delivering such notice via the Depository. The Certificate Administrator shall include in the Form 10-D relating
to the distribution period in which the Asset Review Trigger occurred a description of the events that caused the Asset Review
Trigger to occur. On each Distribution Date after providing such notice to the Certificateholders, the Certificate Administrator,
based on information provided to it by the Master Servicer, shall determine whether (1) any additional Mortgage Loan has become
a Delinquent Loan, (2) any Mortgage Loan has ceased to be a Delinquent Loan and (3) an Asset Review Trigger has ceased to exist,
and, if there is an occurrence of any of the events or circumstances identified in clauses (1), (2) and/or (3), deliver written
notice of such information (which may be via email) in the form of Exhibit SS within two (2) Business Days to the Master
Servicer, the Special Servicer, the Operating Advisor and the Asset Representations Reviewer.

 

If
the Certificateholders evidencing not less than 5% of the Voting Rights of the Certificates deliver to the Certificate Administrator,
within 90 days after the filing of the Form 10-D reporting the occurrence of an Asset Review Trigger, a written direction requesting
a vote to commence an Asset Review (such written direction, the “Asset Review Vote Election”), then the Certificate
Administrator shall promptly provide written notice thereof to the Asset Representations Reviewer and to all Certificateholders
and conduct a solicitation of votes to authorize an Asset Review. Upon the affirmative vote to authorize an Asset Review of Holders
of Certificates evidencing at least a majority of an Asset Review Quorum within 150 days of receipt of the Asset Review Vote Election
(an “Affirmative Asset Review Vote”), the Certificate Administrator shall promptly provide written notice thereof
to all parties to this Agreement, the Underwriters, the Mortgage Loan Sellers, the Directing Holder, the Risk Retention Consultation
Party and the other Certificateholders (the “Asset Review Notice”). Upon receipt of an Asset Review Notice,
the Asset Representations Reviewer shall request access to the Secure Data Room by providing to the Certificate Administrator
a certification in the form attached hereto as Exhibit RR. Upon receipt of such certification, the Certificate Administrator
shall promptly (and in any case within two (2) Business Days after such receipt) grant the Asset Representations Reviewer access
to the Secure Data Room. In the event an Affirmative Asset Review Vote has not occurred within such 150-day period following the
receipt of the Asset Review Vote Election, no Certificateholder may request a vote or cast a vote for an Asset Review and the
Asset Representations Reviewer shall not be required to review any Delinquent Loan unless and until (A) an additional Mortgage
Loan has become a Delinquent Loan after the expiration of such 150-day period, (B) an additional Asset Review Trigger has occurred
as a result or otherwise is in effect, (C) the Certificate Administrator has timely received an Asset Review Vote Election after
the occurrence of the events described in clauses (A) and (B) in this sentence and (D) an Affirmative Asset Review Vote has occurred
within 150 days after the Asset Review Vote Election described in clause (C) in this sentence. After the occurrence of any Asset
Review Vote Election or an Affirmative Asset Review Vote, no Certificateholder may make any additional Asset Review Vote Election
except as described in the immediately preceding sentence. Any reasonable out-of-pocket expenses incurred by the Certificate Administrator
in connection with administering such vote will be paid as an expense of the Trust from the Collection Account. The Certificate
Administrator shall be entitled to administer any vote in connection with the foregoing through an agent.

 

(b)         (i)
If an Affirmative Asset Review Vote has occurred, the Certificate Administrator shall promptly provide written notice thereof
to all parties to this Agreement, the

 

    -469-

     

    

 

Underwriters, Sponsors, the Directing Holder, the Risk Retention Consultation Party and
all other Certificateholders. Upon receipt of an Asset Review Notice, the Custodian (with respect to clauses (1) through (5) for
non-Specially Serviced Loans), the Master Servicer (with respect to clauses (6) and (7) for non-Specially Serviced Loans) and
the Special Servicer (with respect to clauses (6) and (7) for Specially Serviced Loans), in each case to the extent in such party’s
possession, shall promptly, but in no event later than ten (10) Business Days (except with respect to clause (7)) after receipt
of such notice from the Certificate Administrator, provide the following materials to the Asset Representations Reviewer (collectively,
with the Diligence Files, a copy of the Prospectus, a copy of each related Mortgage Loan Purchase Agreement and a copy of this
Agreement posted to the Secure Data Room by the Certificate Administrator pursuant to Section 4.08 or to the Certificate
Administrator’s Website pursuant to Section 3.13(b), as applicable, the “Review Materials”):

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

(ii)          In
the event that, as part of an Asset Review of any Mortgage Loan, the Asset Representations Reviewer determines that it is missing
any documents or agreements that are required to be a part of the Review Materials for such Mortgage Loan or that were entered
into or delivered in connection with the origination or a modification of such Mortgage Loan and, in each case that are necessary
to review and assess one or more documents comprising the Diligence File in connection with its completion of any Test, the Asset
Representations Reviewer shall promptly, but in no event later than ten

 

    -470-

     

    

 

(10) Business Days after receipt of the Review Materials,
notify the Master Servicer (with respect to non-Specially Serviced Loans) or the Special Servicer (with respect to Specially Serviced
Loans), as applicable, of such missing documents and agreements, and request that the Master Servicer or the Special Servicer,
as applicable, promptly, but in no event later than ten (10) Business Days after receipt of such notification from the Asset Representations
Reviewer, to deliver to the Asset Representations Reviewer such missing documents and agreements to the extent in its possession.
In the event any missing documents or agreements are not provided by the Master Servicer or the Special Servicer, as applicable,
within such ten (10) Business Day period, the Asset Representations Reviewer shall contact the related Mortgage Loan Seller to
request such documents or agreements from the Mortgage Loan Seller. The Mortgage Loan Seller will be required to deliver such
additional documents and agreements only to the extent in the possession of such Mortgage Loan Seller.

 

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

 

(iv)      Upon
receipt by the Asset Representations Reviewer of the Asset Review Notice and access to the Review Materials with respect to
a Delinquent Loan, the Asset Representations Reviewer, as an independent contractor, shall commence an Asset Review. The
Asset Representations Reviewer shall perform an Asset Review with respect to each representation and warranty made by the
related Mortgage Loan Seller with respect to such Delinquent Loan in accordance with the Asset Review Standard and the
procedures set forth on Exhibit QQ (each such procedure, a “Test”); provided, however,
that the Asset Representations Reviewer may, but is under no obligation to, modify any Test and/or associated Review
Materials described in Exhibit QQ if, and only to the extent, the Asset Representations Reviewer determines pursuant
to the Asset Review Standard that it is necessary to modify such Test and/or such associated Review Materials in order to
facilitate its Asset Review in accordance with the Asset Review Standard. Once an Asset Review of a Mortgage Loan is
completed, no further Asset Review shall be required in respect of, or performed on, such Mortgage Loan notwithstanding that
such Mortgage Loan may continue to be a Delinquent Loan or again become a Delinquent Loan at a time when a new Asset Review
Trigger occurs and a new Affirmative Asset Review Vote is obtained subsequent to the occurrence of such new Asset Review
Trigger.

 

(v)       No
Certificateholder shall have the right to change the scope of the Asset Review, and the Asset Representations Reviewer shall not
be required to review any information other than (x) the Review Materials and (y) if applicable, Unsolicited Information.

 

(vi)      The
Asset Representations Reviewer may, absent manifest error and subject to the Asset Review Standard, (i) assume, without independent
investigation or

 

    -471-

     

    

 

verification,
that the Review Materials are accurate and complete in all material respects and (ii) conclusively rely on such Review Materials.

 

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

 

(viii)     The
Asset Representations Reviewer shall, within the later of (x) 60 days after the date on which access to the Diligence Files in
the Secure Data Room is made available to the Asset Representations Reviewer by the Certificate Administrator or (y) 10 days after
the expiration of the Cure/Contest Period (whichever is later), complete an Asset Review with respect to each Delinquent Loan
and deliver (i) a report setting forth the Asset Representations Reviewer’s findings and conclusions as to whether or not
it has determined there is any evidence of a failure of any Test based on the Asset Review and a statement that the Asset Representations
Reviewer’s findings and conclusions set forth in such report were not influenced by any third party (an “Asset
Review Report”) to each party to this Agreement and the related Mortgage Loan Seller for each Delinquent Loan, and (ii)
a summary of the Asset Representations Reviewer’s conclusions included in such Asset Review Report (an “Asset Review
Report Summary”) to the Trustee and Certificate Administrator. The period of time by which the Asset Review Report must
be completed and delivered may be extended by up to an additional thirty (30) days, upon written notice to the parties to this
Agreement and the related Mortgage Loan Seller, if the Asset Representations Reviewer determines pursuant to the Asset Review
Standard that such additional time is required due to the characteristics of the Mortgage Loans and/or the Mortgaged Property
or Mortgaged Properties. In no event may the Asset Representations Reviewer determine whether any Test failure constitutes a Material
Defect, or whether the

 

    -472-

     

    

 

Trust
should enforce any rights it may have against the related Mortgage Loan Seller, which, in each such case, will be the responsibility
of the Enforcing Servicer.

 

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

 

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

 

(c)       The
Asset Representations Reviewer and its Affiliates shall keep all information appropriately labeled as “Privileged Information”
confidential and shall not disclose such Privileged Information to any Person (including Certificateholders), other than (1) to
the extent expressly required by this Agreement in an Asset Review Report or otherwise, to the other parties to this Agreement
with a notice indicating that such information is Privileged Information or (2) pursuant to a Privileged Information Exception.
Each party to this Agreement that receives Privileged Information from the Asset Representations Reviewer with a notice stating
that such information is Privileged Information shall not disclose such Privileged Information to any Person without the prior
written consent of the Special Servicer other than pursuant to a Privileged Information Exception.

 

(d)       The
Asset Representations Reviewer may delegate its duties to agents or subcontractors so long as the related agreements or arrangements
with such agents or subcontractors are consistent with the provisions of this Section 12.01; provided that no agent
or subcontractor may (1) be affiliated with a Sponsor, Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator,
the Trustee, the Directing Certificateholder or any of their respective Affiliates or (ii) have been paid any fees, compensation
or other remuneration by an Underwriter, Master Servicer, the Special Servicer, the Depositor, the Certificate Administrator,
the Trustee, the Directing Certificateholder or any of their respective Affiliates in connection with due diligence or other services
with respect to any Mortgage Loan prior to the Closing Date. Notwithstanding the foregoing sentence, the Asset Representations
Reviewer shall remain obligated and primarily liable for any Asset Review required hereunder in accordance with the provisions
of this Agreement without diminution of such obligation or liability or related obligation or liability by virtue of such delegation
or arrangements or by virtue of indemnification from any Person acting as its agents or subcontractor to the same extent and under
the same terms and conditions as if the Asset Representations Reviewer alone were

 

    -473-

     

    

 

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

 

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

 

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

 

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

 

(a)       The
Asset Representations Reviewer shall be paid a fee of $5,000 (the “Asset Representations Reviewer Upfront Fee”)
on the Closing Date. As compensation for the performance of its routine duties, the Asset Representations Reviewer shall be paid
a fee (the “Asset Representations Reviewer Fee”), payable monthly from amounts received in respect of each
Mortgage Loan (including any Non-Serviced Mortgage Loan but excluding any Companion Loan) and REO Mortgage Loan and shall be equal
to the product of a rate equal to 0.00026% per annum (the “Asset Representations Reviewer Fee Rate”)
and the Stated Principal Balance of the

 

    -474-

     

    

 

Mortgage
Loans and any REO Loans and shall be calculated in the same manner as interest is calculated on such Mortgage Loans and REO Loans.

 

(b)       As
compensation for the performance of its duties hereunder, with respect to an individual Asset Review Trigger and the Mortgage
Loans that are Delinquent Loans and are subject to an Asset Review (for purposes of this Section 12.02(b), “Subject
Loans”), upon the completion of any Asset Review with respect to an individual Asset Review Trigger, the Asset Representations
Reviewer shall be paid a fee of: (i) $15,000 plus $1,000 per additional Mortgaged Property with respect to a Delinquent Loan with
Cut-off Date Balance less than $20,000,000, (ii) $20,000 plus $1,000 per additional Mortgaged Property with respect to a Delinquent
Loan with a Cut-off Date Balance greater than or equal to $20,000,000, but less than $40,000,000 or (iii) $25,000 plus $1,000
per additional Mortgaged Property with respect to a Delinquent Loan with a Cut-off Date Balance greater than or equal to $40,000,000
(the “Asset Representations Reviewer Asset Review Fee”). The Asset Representations Reviewer Asset Review Fee
with respect to each Delinquent Loan shall be paid by the related Mortgage Loan Seller within forty-five (45) days of receipt
by the related Mortgage Loan Seller of a written invoice from the Asset Representations Reviewer. If the related Mortgage Loan
Seller (x) is insolvent or (y) fails to pay such amount upon completion of any Asset Review and within 90 days of receiving an
invoice from the asset representations reviewer, such fee shall be paid by the Trust following delivery by the Asset Representations
Reviewer of evidence reasonably satisfactory to the Master Servicer or the Special Servicer, as applicable, of such insolvency
or failure to pay such amount; provided, however, that a statement of non-payment by the Asset Representations Reviewer
ninety (90) days after an itemized invoice is delivered by registered mail to the address listed in this Agreement for the related
Mortgage Loan Seller, or to such other address as shall be provided by such Mortgage Loan Seller for delivery of notice in accordance
with this Agreement, together with evidence of delivery or attempted delivery of such invoice and reasonable follow up by phone
or email, shall constitute satisfactory evidence delivered by the Asset Representations Reviewer of such failure to pay such amount.
Notwithstanding any payment of such fee by the Trust to the Asset Representations Reviewer, such fee will remain an obligation
of the related Mortgage Loan Seller and the Special Servicer shall reasonably pursue remedies against such Mortgage Loan Seller
to recover any such amounts to the extent paid by the Trust, provided that the costs of doing so will be a cost of the Trust.

 

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

 

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

 

Section
12.03    Resignation of the Asset Representations Reviewer. The Asset Representations Reviewer

of such termination and other than indemnification rights arising out of events occurring prior to such termination) by notice
in writing to the Asset Representations Reviewer. As between the Asset Representations Reviewer, on the one hand, and the Certificateholders,

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

 

The
Asset Representations Reviewer shall be at all times an Eligible Asset Representations Reviewer and if the Asset Representations
Reviewer ceases to be an Eligible Asset Representations Reviewer, the Asset Representations Reviewer shall immediately notify
the Master Servicer, the Special Servicer, the Trustee, the Operating Advisor, the Certificate Administrator and the Directing
Holder of such disqualification and immediately resign under Section 12.03 of this Agreement and the Trustee shall appoint
a successor asset representations reviewer subject to and in accordance with this Section 12.05. Notwithstanding the foregoing,
if the Trustee is unable to find a successor asset representations reviewer within 30 days of the

 

    -478-

     

    

 

termination
of the Asset Representations Reviewer, the Depositor shall be permitted to find a replacement. The Trustee shall not be liable
for any failure to identify and appoint a successor asset representations reviewer for so long as the Trustee uses commercially
reasonable efforts to conduct a search for a successor asset representations reviewer and such failure is not a result of the
Trustee’s negligence, bad faith or willful misconduct in the performance of its obligations hereunder.

 

(d)       Upon
any termination of the Asset Representations Reviewer and appointment of a successor to the Asset Representations Reviewer, the
Trustee shall, as soon as possible, give written notice thereof to the Special Servicer, the Master Servicer, the Certificate
Administrator (who shall, as soon as possible, give written notice thereof to the Certificateholders), the Operating Advisor,
the Sponsors, the Depositor and, prior to the occurrence and continuance of a Consultation Termination Event, the Directing Holder
and each Rating Agency. In the event that the Asset Representations Reviewer is terminated, all of its rights and obligations
under this Agreement shall terminate, other than any rights or obligations that accrued prior to the date of such termination
(including the right to receive all amounts accrued and owing to it under this Agreement) and other than indemnification rights
(arising out of events occurring prior to such termination).

Section
13.07    Grant of a Security Interest. The Depositor intends that the conveyance of the Depositor’s

also intends and agrees that, in such event, (i) the Depositor shall be deemed to have granted to the Trustee (in such capacity)

the Mortgage Loans (other than principal and interest payments due and payable prior to the Cut-off Date and Principal Prepayments
received prior to the Cut-off Date), all amounts held from time to time in the Collection Account, the Distribution Accounts,
the Gain-on-Sale Reserve Account, the Interest Reserve Account and, if established, the REO Account, and all reinvestment earnings
on such amounts, and all of the Depositor’s right, title and interest in and to the proceeds of any title, hazard or other
Insurance Policies related to such Mortgage Loans and (ii) this Agreement shall constitute a security agreement under applicable
law. The Depositor shall file or cause to be filed, as a precautionary filing, a UCC Financing Statement in all appropriate locations
promptly following the initial issuance of the Certificates to reflect the assignments made by the Mortgage Loan Sellers to the
Depositor (and the Trustee) and by the Depositor to the Trustee (copies of which shall be delivered by the Depositor to the Certificate
Administrator shall, at the expense of the Depositor (to the extent reasonable), no later than 10 days following the Closing Date),
and the Certificate Administrator shall prepare and file continuation statements with respect thereto, in each case in the six
month period prior to every fifth anniversary of the date of the initial UCC Financing Statement. The Depositor shall cooperate
in a reasonable manner with the Certificate Administrator in the preparation and filing of such continuation statements. This
Section 13.07 shall constitute notice to the Certificate Administrator and the Trustee pursuant to any of the requirements
of the applicable UCC.

 

Section
13.08  Successors and Assigns; Third Party Beneficiaries. (a) The provisions of this Agreement shall be binding upon
and inure to the benefit of the respective successors and assigns of the parties hereto, and all such provisions shall inure to
the benefit of the Certificateholders. Each Mortgage Loan Seller (and its respective agents), each Companion Holder (and its respective
agents), each Underwriter, each depositor of a Regulation AB Companion Loan Securitization and each Initial Purchaser is an intended
third-party beneficiary to this Agreement in respect of the respective rights afforded it hereunder. No other person, including,
without limitation, any Mortgagor, shall be entitled to any benefit or equitable right, remedy or claim under this Agreement.

 

(b)       Each
Serviced Companion Noteholder shall be a third-party beneficiary to this Agreement in respect to the rights afforded it hereunder.
Each of the Other Servicers and the Other Trustees shall be a third-party beneficiary to this Agreement in respect to all provisions
herein expressly relating to compensation, reimbursement or indemnification of such Other Servicer and Other Trustee, and any
provisions regarding reimbursement or advances or interest thereon to such Other Servicer or Other Trustee.

be an express third-party beneficiary to this Agreement for purposes of exercising rights under Section 2.03(k) through
Section 2.03(o).

 

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

This
certifies that [          ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-1 Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
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-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class
A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E,

 

     A-1-3

     

    

 

Class
V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class A-1 Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
A-1 Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this
Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise

 

     A-1-4

     

    

 

 (b)
by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the

 

     A-1-5

     

    

 

extent of
the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution
Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent
of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the extent of the Trust’s interest
in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent
of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement
(to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other
than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts,
to the extent such interest belongs to the related Mortgagor).

 

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

 

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

 

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

 

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

 

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

                                         with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or
                                         to correct or supplement any of its provisions which may be inconsistent with any other
                                         provisions therein or to correct any error;

  

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

 

		(iv)	to

                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action

                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance

Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage

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

 

		(iii)	adversely

                                         of all Certificates of such Class then outstanding; or

 

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the
                                         Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

     A-1-10

     

    

 

thereby
effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution
Date on which the aggregate Stated Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust
is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
or the Mortgage Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class A-1 Certificate to be duly executed.

This
certifies that [          ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-2 Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class
A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E,

 

     A-2-3

     

    

 

Class
V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class A-2 Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
A-2 Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this
Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise

 

     A-2-4

     

    

 

(b)
by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the

 

     A-2-5

     

    

 

extent
of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution
Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent
of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the extent of the Trust’s interest
in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent
of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement
(to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other
than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts,
to the extent such interest belongs to the related Mortgagor).

 

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

 

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

 

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

 

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

                                         cause the provisions in the Pooling and Servicing Agreement to conform or be consistent
                                         with or in furtherance of the statements made in the Prospectus (or in an offering document
                                         for any related non-offered

with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;

 

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

 

		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), or Companion Holder;

                                         Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer
                                         of the Class R Certificates; provided the Depositor has determined that such change
                                         shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or
                                         any of the Certificateholders (other than the Transferor) to be subject to a federal

                                         shall post such notice to the Certificate Administrator’s Website;

 

		(x)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to comply with the requirements for use of Form SF-3
                                         in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv);
                                         or

 

		(xi)	to
                                         modify, eliminate or add to any of its provisions in the event the Credit Risk Retention
                                         Rules or any other regulations applicable to the risk retention requirements for this
                                         securitization transaction are amended or repealed, to the extent required to comply
                                         with any such amendment or to modify or eliminate the provision related to the risk retention
                                         requirements in the event of such repeal.

 

Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage
                                         Loans that are required to be distributed on a Certificate of any class without the consent
                                         of the Holder of the Certificate or which are required to be distributed to a Companion
                                         Holder without the consent of such Companion Holder; or

 

     A-2-9

     

    

 

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

 

		(iii)	adversely
                                         affect the Voting Rights of any Class of Certificates without the consent of the Holders
                                         of all Certificates of such Class then outstanding; or

 

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the
                                         Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

     A-2-10

     

    

 

thereby
effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution
Date on which the aggregate Stated Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust
is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
or the Mortgage Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class A-2 Certificate to be duly executed.

This
certifies that [          ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class A-3 Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class
A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class
V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together

 

     A-3-3

     

    

 

with
the Class A-3 Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein
as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class
A-3 Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this
Certificate may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final

 

     A-3-4

     

    

 

distribution
on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of
the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent

 

     A-3-5

     

    

 

of
the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the
Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale
Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the
extent of the Trust’s interest in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental
Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under
each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; and (xii)
the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

 

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

 

As
provided in the Pooling and Servicing Agreement, subject to certain restrictions on transfer set forth therein, upon surrender

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

the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage

		(ii)	reduce
                                         the aforesaid percentage of Certificates of any Class the Holders of which are required

                                         of all Certificates of such Class then outstanding; or

 

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the
                                         Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

     A-3-10

     

    

 

thereby
effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution
Date on which the aggregate Stated Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust
is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment

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 and multifamily 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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class
A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class
V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together

 

     A-4-3

     

    

 

with
the Class A-4 Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein
as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, 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 immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final

 

     A-4-4

     

    

 

distribution
on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of
the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent

 

     A-4-5

     

    

 

of
the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the
Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale
Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the
extent of the Trust’s interest in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental
Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under
each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; and (xii)
the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

 

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

 

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

 

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

 

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

 

		(i)	to

		(ii)	to
                                         cause the provisions in the Pooling and Servicing Agreement to conform or be consistent

Agreement or to correct or supplement any of its provisions which may be inconsistent with any other provisions therein or to
correct any error;

 

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

 

		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to
                                         modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing
                                         Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer
                                         of the Class R Certificates; provided the Depositor has determined that such change
                                         shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or
                                         any of the Certificateholders (other than the Transferor) to be subject to a federal
                                         tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S.

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

Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage
                                         Loans that are required to be distributed on a Certificate of any class without the consent
                                         of the Holder of the Certificate or which are required to be distributed to a Companion
                                         Holder without the consent of such Companion Holder; or

 

     A-4-9

     

    

 

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

 

		(iii)	adversely

                                         of all Certificates of such Class then outstanding; or

 

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the
                                         Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

		(v)	amend
                                         the Servicing Standard without the consent of 100% of the Certificateholders or receipt
                                         of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
                                         rating agencies that such action will not result in the downgrade, withdrawal or qualification
                                         of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied in the same manner
                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under
                                         the related Intercreditor Agreement, the consent of the holder of any AB Subordinate
                                         Companion Loan for each Serviced AB Whole Loan.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

     A-4-10

     

    

 

thereby
effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution
Date on which the aggregate Stated Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust
is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
or the Mortgage Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class A-4 Certificate to be duly executed.

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

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September

Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance

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-5
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise

 

    A-5-4 

     

    

 

(b)
by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the

 

    A-5-5 

     

    

 

extent
of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution
Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to
the extent of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the extent of the
Trust’s interest in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; and (xii) the proceeds
of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts
and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

 

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

 

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

 

Prior
to due presentation of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating
Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent
of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate

Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.

 

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

 

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

 

		(ii)	to
cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with or in furtherance of the statements
made in the Prospectus (or in an offering document for any related non-offered 

 

    A-5-6 

     

    

 

certificates)
with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;

 

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

 

		(iv)	to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to maintain
the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the Code
at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition of any tax on the Trust or any
Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have received an Opinion of Counsel
(at the expense of the party requesting such amendment) to the effect that (a) such action is necessary or desirable to maintain
such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action will not adversely affect
in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest),
or Companion Holder;

 

		(v)	to
modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement or any other provision of
the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided the Depositor has determined
that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders
(other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that is a Disqualified Organization
or a Non-U.S. Tax Person;

 

		(vi)	to
revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any
other change; provided that the required action shall not adversely affect in any material respect the interests of any
Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest) or any holder of a Serviced Pari Passu
Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of
the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect
to such 

 

    A-5-7 

     

    

 

amendment
or supplement and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal
or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(vii)	to
amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary to maintain the then-current
ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency Confirmation from each of
the Rating Agencies and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal
or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if any (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement); provided that
such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder (including,
for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion
of Counsel;

 

		(viii)	to
modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable
Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as
a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded
Loan, as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of
the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such
provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status
of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code,
as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to
any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation that such action
will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that such rating
agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied
with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

    A-5-8 

     

    

 

		(ix)	to
modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5 of the Exchange Act;
provided that such amendment shall not adversely affect in any material respects the interests of any Certificateholders
(including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if
any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates; and provided,
further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information Provider for
posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and
the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

 

		(x)	to
modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent as shall be necessary to comply
with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv);
or

 

		(xi)	to
modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules or any other regulations applicable
to the risk retention requirements for this securitization transaction are amended or repealed, to the extent required to comply
with any such amendment or to modify or eliminate the provision related to the risk retention requirements in the event of such
repeal.

 

Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage
                                         Loans that are required to be distributed on a Certificate of any class without the consent
                                         of the Holder of the Certificate or which are required to be distributed to a Companion
                                         Holder without the consent of such Companion Holder; or

 

    A-5-9 

     

    

 

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

 

		(iii)	adversely
                                         affect the Voting Rights of any Class of Certificates without the consent of the Holders
                                         of all Certificates of such Class then outstanding; or

 

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations

                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the
                                         Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

		(v)	amend the Servicing
                                                                                                                                              Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating
                                                                                                                                              Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or
                                                                                                                                              qualification of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such
                                                                                                                                              rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
                                                                                                                                              satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required
                                                                                                                                              under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced
                                                                                                                                              AB Whole Loan.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

    A-5-10 

     

    

 

thereby
effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution
Date on which the aggregate Stated Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust
is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the
Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other
than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for
all of the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing
Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
or the Mortgage Loans.

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

Class
V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class A-SB Certificates,
the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-SB
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise 

 

    A-6-3 

     

    

 

(b)
by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

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

interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the

 

    A-6-4 

     

    

 

extent
of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution
Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to
the extent of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the extent of the
Trust’s interest in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; and (xii) the proceeds
of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts
and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

 

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

 

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

Certificate for the purpose of receiving distributions as provided in the Pooling and Servicing Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer,
the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar
shall be affected by any notice to the contrary.

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

                                         is necessary or desirable to maintain such qualification or to avoid or minimize the

                                         of the Class R Certificates; provided the Depositor has determined that such change
                                         shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or

                                         Rules or any other regulations applicable to the risk retention requirements for this

                                         with any such amendment or to modify or eliminate the provision related to the risk retention
                                         requirements in the event of such repeal.

 

Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage
                                         Loans that are required to be distributed on a Certificate of any class without the consent
                                         of the Holder of the Certificate or which are required to be distributed to a Companion
                                         Holder without the consent of such Companion Holder; or

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

                                         of all Certificates of such Class then outstanding; or

 

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the

                                                                                                                                              under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced
                                                                                                                                              AB Whole Loan.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

    A-6-9 

     

    

 

thereby
effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution
Date on which the aggregate Stated Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust
is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the
Sole Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other
than the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for
all of the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing
Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
or the Mortgage Loans.

This

interest in a Trust Fund, including the distributions to be made with respect to the Class X-A Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
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

Class
V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class X-A Certificates,
the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-A
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise

 

    A-7-4 

     

    

 

(b)
by check mailed to such Certificateholder at its address in the Certificate Register. The final distribution on each Certificate
will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of the Certificate Registrar
or such other location specified in the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the

 

    A-7-5 

     

    

 

extent
of the Trust’s interest therein), amounts on deposit in the Collection Account (to the extent of the Trust’s interest
therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution
Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to
the extent of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the extent of the
Trust’s interest in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental Indemnity
Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under each Mortgage
Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; and (xii) the proceeds
of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts, escrow accounts
and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

 

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

    A-8-3

     

    

 

with the Class X-B Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
beneficial ownership of 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,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-B Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final

 

    A-8-4

     

    

 

distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent

 

    A-8-5

     

    

 

of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale
Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

 

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

 

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

 

		(ii)	to cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with
or in furtherance of the statements made in the Prospectus (or in an offering document for any related non-offered certificates)

Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;

 

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

of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have
received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary
or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided

or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to revise or add any other provisions
with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that
the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for
the avoidance of doubt, any Holder of a VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement

any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced
by an Opinion of Counsel;

 

		(viii)	to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with
respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master
Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect
to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder,
the Holder of the majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided
that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

    A-8-8

     

    

 

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5
of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any
Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such
Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to
the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the
Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s
Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

    A-8-9

     

    

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

    A-8-10

     

    

 

thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

The Trust Fund, described more
fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily 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-5, Class A-SB, Class X-A, Class X-B, Class
A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z,
Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class X-E Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
beneficial ownership of 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,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of interest then distributable, if any, allocable to the Class X-E 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-E Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

    A-9-4

     

    

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

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

 

    A-9-5

     

    

 

Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale
Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

    A-9-10

     

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

    A-9-11

     

    

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-E, Class B and Class
C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders acting in
unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

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 and multifamily 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-5, Class A-SB, Class X-A, Class X-B,
Class X-E, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D,

    A-10-3

     

    

 

(together with the Class A-S
Certificates, the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
beneficial ownership of 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,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class A-S
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final

 

    A-10-4

     

    

 

distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent

 

    A-10-5

     

    

 

of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

 

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

 

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

 

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

Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;

 

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

 

		(iv)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under

of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have
received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary
or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided

or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to revise or add any other provisions
with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that

the avoidance of doubt, any Holder of a VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement
and confirmation of the applicable rating

 

    A-10-7

in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced
by an Opinion of Counsel;

 

		(viii)	to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with
respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master
Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect
to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder,
the Holder of the majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided
that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

    A-10-8

     

    

 

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5
of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any
Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such
Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to
the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the
Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s
Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

    A-10-9

     

    

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

    A-10-10

     

    

 

thereby
effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution
Date on which the aggregate Stated Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust
is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans

Class
V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class B Certificates,
the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
beneficial ownership of 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,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class B Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise

 

    A-11-4

     

    

 

(b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the

 

    A-11-5

     

    

 

extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

 

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

 

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

 

		(ii)	to cause the provisions in the Pooling and Servicing Agreement to conform or be consistent with
or in furtherance of the statements made in the Prospectus (or in an offering document for any related non-offered 

 

    A-11-6

     

    

 

certificates)
with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or to correct or supplement any of its provisions
which may be inconsistent with any other provisions therein or to correct any error;

 

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

 

		(iv)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under

of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have
received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary
or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided

or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to revise or add any other provisions
with respect to matters or questions arising under the Pooling and Servicing Agreement or any other change; provided that
the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for
the avoidance of doubt, any Holder of a VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such

 

    A-11-7

     

    

 

amendment or supplement and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced
by an Opinion of Counsel;

 

		(viii)	to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with
respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master
Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect
to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder,
the Holder of the majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided
that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

    A-11-8

     

    

 

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5
of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any
Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such
Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to
the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the
Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s
Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

    A-11-9

     

    

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

    A-11-10

     

    

 

thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction

    A-12-3 

     

    

 

(together
with the Class C Certificates, the “Certificates”; the Holders of Certificates are collectively referred
to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class C
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

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

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final

 

    A-12-4 

     

    

 

distribution
on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices of
the Certificate Registrar or such other location specified in the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent

 

    A-12-5 

     

    

 

of
the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the Upper-Tier REMIC Distribution Account, the
Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest Reserve Account, the Gain-on-Sale
Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale Reserve Account) and any REO Account (to the
extent of the Trust’s interest in such REO Account), including any reinvestment income, as applicable; (ix) any Environmental
Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies of the Depositor under
each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular Interests; and (xii)
the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash collateral accounts,
escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

 

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

 

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

 

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

 

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

Agreement or to correct or supplement any of its provisions which may be inconsistent with any other provisions therein or to
correct any error;

 

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

 

		(iv)	to
                                         modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to
                                         such extent as shall be necessary to maintain the qualification of any Trust REMIC as
                                         a REMIC or the Grantor Trust as a grantor trust under the relevant provisions of the
                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided
                                         that the Trustee and the Certificate Administrator have received an Opinion of Counsel
                                         (at the expense of the party requesting such amendment) to the effect that (a) such action
                                         is necessary or desirable to maintain such qualification or to avoid or minimize the
                                         risk of the imposition of any such tax and (b) such action will not adversely affect
                                         in any material respect the interests of any Certificateholder (including, for the avoidance
                                         of doubt, any Holder of a VRR Interest), or Companion Holder;

                                         Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer
                                         of the Class R Certificates; provided the Depositor has determined that such change
                                         shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or
                                         any of the Certificateholders (other than the Transferor) to be subject to a federal

                                         the Pooling and Servicing Agreement or any other change; provided that the required

Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to

                                                                                                                                              rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
                                                                                                                                              satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required
                                                                                                                                              under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced
                                                                                                                                              AB Whole Loan.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

    A-12-10 

     

    

 

thereby
effect termination of the Trust and early retirement of the then-outstanding Certificates, only on or after the first Distribution
Date on which the aggregate Stated Principal Balances of the Mortgage Loans and the portion of any REO Loans held by the Trust
is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
or the Mortgage Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class C Certificate to be duly executed.

This
certifies that [           ] is the registered owner of a beneficial ownership
interest in a Trust Fund, including the distributions to be made with respect to the Class D Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
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-5, Class A-SB, Class X-A, Class X-B, Class
X-E, Class A-S, Class B, Class C, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E,
Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class D Certificates,
the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, 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

 

    A-13-4 

     

    

 

Accrual
Period” with respect to any Distribution Date and with respect to the Class D Certificates is the calendar month
immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

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

the Certificate Administrator’s and the Trustee’s rights under the insurance policies with respect to the Mortgage
Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof (to the extent of the
Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent of the Trust’s
interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given as additional security
for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in the Loss
of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit in

REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account, the Interest

and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment income, as applicable;
(ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the rights and remedies
of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi) the Lower-Tier Regular
Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box accounts, cash
collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related Mortgagor).

 

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

 

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

 

Prior

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

Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce
                                         in any manner the amount of, or delay the timing of, payments received on the Mortgage
                                         Loans that are required to be distributed on a Certificate of any class without the consent
                                         of the Holder of the Certificate or which are required to be distributed to a Companion
                                         Holder without the consent of such Companion Holder; or

 

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

 

		(iii)	adversely
                                         affect the Voting Rights of any Class of Certificates without the consent of the Holders
                                         of all Certificates of such Class then outstanding; or

 

		(iv)	change
                                         in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
                                         of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
                                         or change any rights of any Mortgage Loan Seller as a third party beneficiary under the
                                         Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller; or

 

		(v)	amend the Servicing
                                                                                                                                              Standard without the consent of 100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating
                                                                                                                                              Agency and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or

                                                                                                                                              satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required
                                                                                                                                              under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each Serviced
                                                                                                                                              AB Whole Loan.

 

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

 

    A-13-10 

     

    

 

effect
that such amendment is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied
and that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee, the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person
in accordance with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC,
or cause any Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under
the relevant provisions of the Code.

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
or the Mortgage Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class D Certificate to be duly executed.

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 E Certificates. The Trust Fund, described
more fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties
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-5, Class A-SB, Class X-A, Class X-B,
Class X-E, Class A-S, Class B, Class C, Class D, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class
V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class E Certificates,
the “Certificates”; the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class E
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 E Certificates

 

    A-14-5 

     

    

 

is
the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with

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

the foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator,
the Depositor, the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing
Agreement without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment
is permitted under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment
or the exercise of any power

 

    A-14-11 

     

    

 

granted
to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the Operating Advisor,
the Asset Representations Reviewer or any other specified person in accordance with such amendment will not result in the imposition
of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify as a REMIC or cause
the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes
no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates
or the Mortgage Loans.

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class E Certificate to be duly executed.

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 and multifamily 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-5, Class A-SB, Class X-A, Class X-B,
Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class NR, Class V1-A, Class V1-B, Class V1-D, Class
V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class 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 September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
beneficial ownership of 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,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class 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 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

 

    A-15-5 

     

    

 

is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

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

 

    A-15-6 

     

    

 

Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

 

    A-15-7 

     

    

 

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

 

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

 

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

 

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

 

		(iv)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC or the Grantor Trust as a grantor trust under
the relevant provisions of the Code at all times that any Certificate is outstanding, or to avoid or minimize the risk of imposition
of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have
received an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that (a) such action is necessary
or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided
the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC
or any of the Certificateholders (other than the Transferor) to be subject to a 

 

    A-15-8 

     

    

 

federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to revise or add any other provisions with respect to matters or questions arising under the Pooling
and Servicing Agreement or any other change; provided that the required action shall not adversely affect in any material
respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest) or any holder
of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel,
at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies
with respect to such amendment or supplement and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced
by an Opinion of Counsel;

 

		(viii)	to modify the provisions of Sections
3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed
Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event
has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the
Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed,
in order to

 

    A-15-9 

     

    

 

conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided
that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5
of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any
Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such
Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to
the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the
Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s
Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment

 

    A-15-10 

     

    

 

(including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power

 

    A-15-11 

     

    

 

granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

This certifies that
[           ] is the registered owner of a beneficial ownership interest
in a Trust Fund, including the distributions to be made with respect to the Class NR Certificates. The Trust Fund, described more
fully below, consists primarily of a pool of Mortgage Loans secured by first liens on commercial and multifamily properties 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-5, Class A-SB, Class X-A, Class X-B,
Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class V1-A, Class V1-B, Class V1-D,
Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class Z Certificates (together with the Class 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 September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
beneficial ownership of 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,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class 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 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

 

    A-16-5 

     

    

 

Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

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

 

    A-16-6 

     

    

 

Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

 

    A-16-7 

     

    

 

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

 

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

 

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

 

		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts

federal tax caused by a Transfer to a Person that

of a Serviced Pari Passu Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel,
at the expense of the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies

has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing

Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed,
in order to

conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation

satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5
of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any
Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such
Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to
the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the

or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment

 

    A-16-10 

     

    

 

(including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

Notwithstanding the
foregoing, none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator, the Depositor,
the Master Servicer nor the Special Servicer will be required to consent to any amendment to the Pooling and Servicing Agreement
without having first received an Opinion of Counsel (at the Trust’s expense) to the effect that such amendment is permitted
under the Pooling and Servicing Agreement, that all conditions precedent have been satisfied and that such amendment or the exercise
of any power

 

    A-16-11 

     

    

 

granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate Administrator, the
Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such amendment will not
result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC to fail to qualify
as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of the Code.

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

of a pool of Mortgage Loans secured by first liens on commercial and multifamily 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

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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C,
Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class
V2-A, Class V2-Z and Class Z Certificates (together with the Class R Certificates, the “Certificates”;
the Holders of Certificates are collectively referred to herein as “Certificateholders”).

 

This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
a “residual interest” in three “real estate mortgage investment conduits,” as those terms are defined,
respectively, in Sections 860G(a)(2) and 860D of the Internal Revenue Code of 1986, as amended.

 

Each Holder of this
Certificate, by acceptance hereof, agrees to treat, and take no action inconsistent with the treatment of, this Certificate in
accordance with the preceding sentence for purposes of federal income taxes, state and local income and franchise taxes and other
taxes imposed on or measured by income. The Holder of the largest Percentage Interest in the Class R Certificates shall be the
“tax matters person” pursuant to Treasury Regulations Section 1.860F 4(d) and “partnership representative”
(within the meaning of Section 6223 of the Code, to the extent such provision is applicable to the Trust REMICs) for each Trust
REMIC, and the Certificate Administrator is hereby irrevocably designated and shall serve as attorney in fact and agent for any
such Person that is the “tax matters person” or “partnership representative”.

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of the aggregate amount, if any, 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

 

    A-18-4 

     

    

 

close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the

 

    A-18-5 

     

    

 

Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

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

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

    A-18-9 

     

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations

Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

    A-18-10 

     

    

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

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 September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,

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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount, if any, allocable to the Class Z Certificates for such Distribution Date, all as
more fully described in the Pooling and Servicing Agreement.

 

All distributions

Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate

surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of

of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

    A-18-5 

     

    

 

which may be inconsistent with any other provisions therein or to correct any error;

 

		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts
or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior
to the related Distribution Date and (b) such change shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest), as evidenced in writing by an Opinion of Counsel at the

to such amendment;

 

		(iv)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent

or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to revise or add any other provisions

such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement
and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or

qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation

		(vii)	to amend or supplement any provision of the Pooling and Servicing Agreement to the extent necessary
to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced
by an Opinion of Counsel;

 

		(viii)	to modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with
respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master
Servicer, the Trustee and, for so long as a Control Termination Event has not occurred and is not continuing and, with respect
to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder,
the Holder of the majority of the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities
industry standard for such provisions has changed, in order to conform to such industry standard, (b) such modification does not
adversely affect the status of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant
provisions of the Code, as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation
and, with regard to any class of Serviced Companion Loan Securities, the applicable rating agencies have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided
that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

    A-18-7 

     

    

 

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule 17g-5
of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests of any
Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such
Certificates; and provided, further, that the Certificate Administrator shall give notice of any such amendment to
the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the
Pooling and Servicing Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s
Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

    A-18-8 

     

    

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

    A-18-9 

     

    

 

thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

This
certifies that [              ] is the registered
owner of a beneficial ownership interest in a Trust Fund, including the distributions to be made with respect to the Class V1-A
Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens
on commercial and multifamily properties 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,

 

    		A-19-3	 

     

    

 

Class A-2,
Class A-3, Class A-4, Class A-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D,
Class E, Class F, Class NR, Class V1-B, Class V1-D, Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class
R and Class Z Certificates (together with the Class V1-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 September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of multiple “regular interests” 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-A
Certificates for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate
may be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

Interest
accrued on this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this
Certificate, if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement.
The “Interest Accrual Period” with respect to any Distribution Date and with respect to the Class V1-A
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions

 

    		A-19-4	 

     

    

 

no
less than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order
applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in
the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and
surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders
of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as

 

    		A-19-5	 

     

    

 

additional
security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets deposited in
the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts on deposit
in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account, the

                                         Code at all times that any Certificate is outstanding, or to avoid or minimize the risk
                                         of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided

                                         of the Class R Certificates; provided the Depositor has determined that such change
                                         shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC or

less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner

                                         as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
                                         pursuant to Section 3.25 of the Pooling and Servicing Agreement) and, if required under

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

or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee, the Certificate
Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance with such
amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any Trust REMIC
to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant provisions of
the Code.

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate

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 V1-B
Certificates. The Trust Fund, described more fully below, consists primarily of a pool of Mortgage Loans secured by first liens
on commercial and multifamily properties 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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E,
Class F, Class NR, Class V1-A, Class V1-D,

 

    		A-20-3	 

     

    

 

Class V1-E, Class V1-F, Class V1-Z, Class V2-A, Class V2-Z, Class R and Class
Z Certificates (together with the Class V1-B Certificates, the “Certificates”; the Holders of Certificates
are collectively referred to herein as “Certificateholders”).

 

This
Certificate is issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of multiple “regular interests” 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-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 V1-B
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise

 

    		A-20-4	 

     

    

 

(b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the

 

    		A-20-5	 

     

    

 

extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x)
the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).

 

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

 

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

 

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

 

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

 

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

 

		(ii)	to cause the provisions in the Pooling and Servicing
Agreement to conform or be consistent with or in furtherance of the statements made in the Prospectus (or in an offering document
for any related non-offered 

 

    		A-20-6	 

     

    

 

certificates) with respect to the Certificates, the Trust or the Pooling and Servicing Agreement or
to correct or supplement any of its provisions which may be inconsistent with any other provisions therein or to correct any error;

 

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

 

		(iv)	to modify, eliminate or add to any provisions of the
Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC
or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding,
or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that
the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such
amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize
the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests
of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to modify, eliminate or add to the provisions of Section
5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer
of the Class R Certificates; provided the Depositor has determined that such change shall not, as evidenced by an Opinion
of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal
tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to
revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any
other change; provided that the required action shall not adversely affect in any material respect the interests of any
Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest) or any holder of a Serviced Pari Passu
Companion Loan not consenting to such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of
the party requesting such amendment or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect
to such 

 

    		A-20-7	 

     

    

 

amendment or supplement and confirmation
of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current
ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be
considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(vii)	to amend or supplement any provision of the Pooling
and Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by
each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered
satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant
to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely
affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a
VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

 

		(viii)	to modify the provisions of Sections 3.05 and 3.17
of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed Reimbursement
Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event has not occurred
and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing Holder or, if
the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the Directing Holder,
determine that the commercial mortgage backed securities industry standard for such provisions has changed, in order to conform
to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as a REMIC or the status
of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion of Counsel and (c)
each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion Loan Securities,
the applicable rating agencies have delivered a confirmation that such action will not result in the downgrade, withdrawal or
qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in
the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section
3.25 of the Pooling and Servicing Agreement);

 

    		A-20-8	 

     

    

 

		(ix)	to modify the procedures of the Pooling and Servicing
Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely
affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of
a VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating
Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice
to the Certificate Administrator’s Website;

 

		(x)	to modify, eliminate or add to any provisions of the
Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered
offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions
in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization
transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision
related to the risk retention requirements in the event of such repeal.

 

Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

		(i)	reduce in any manner the amount of, or delay the timing
of, payments received on the Mortgage Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or

 

    		A-20-9	 

     

    

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of
Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage
Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without
the consent of such Mortgage Loan Seller; or

 

		(v)	amend the Servicing Standard without the consent of
100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to
Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of
the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

 

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

 

The
Holders of the majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates
may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and

 

    		A-20-10	 

     

    

 

thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following
the date on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class
X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple
Holders acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole
Certificateholder shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than
the Class Z and Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of
the Mortgage Loans and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The
obligations created by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate
Administrator to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate
upon reduction of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment
resulting from a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement.
In no event, however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court
of St. James, living on the date hereof.

 

Unless
the certificate of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate
shall not be entitled to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar
has executed this Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes

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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E,

Z Certificates (together with the Class V1-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 September
1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities
Corp., as Depositor, Wells Fargo Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance
LLC, as Operating Advisor and as Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto
Capital Advisors, LLC, as Special Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings
assigned thereto in the Pooling and Servicing Agreement.

 

This
Certificate represents beneficial ownership of 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, 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 October 2017 (each
such date, a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related
Record Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this
Certificate) of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-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 V1-D
Certificates is the calendar month immediately preceding the month in which such Distribution Date occurs and is assumed to consist
of 30 days.

 

All
distributions (other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons
in whose names the Certificates are registered at the

 

    		A-21-4	 

     

    

 

close of business on each Record Date, which will be the close of business
on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are
required to be made (a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder provided the Certificate Administrator with written
wiring instructions no less than five Business Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder
at its address in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the offices of the Certificate Registrar or such other location specified in
the notice to Certificateholders of such final distribution.

 

Any
funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure
of such Certificateholders to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited
to the account or accounts of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to Section 4.01(h) of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within
six months after the time specified in such notice, the Certificate Administrator shall mail a second notice to the remaining
non tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with
respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation,
the Certificate Administrator, directly or through an agent, shall take such steps to contact the remaining non tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate and subject to escheatment and other applicable laws.
The costs and expenses of holding such funds in trust and of contacting such Certificateholders following the first anniversary
of the delivery of such second notice to the non-tendering Certificateholders shall be paid out of such funds. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust under the Pooling and Servicing Agreement by the Certificate
Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof
in accordance with Section 4.01(h) of the Pooling and Servicing Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the

 

    		A-21-5	 

     

    

 

Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds
thereof (to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the
extent of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies
given as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all
assets deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein),
amounts on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution
Account, the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution
Account, the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x)
the rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee);
(xi) the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in
the lock-box accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs
to the related Mortgagor).

 

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

 

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

 

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

 

The
Pooling and Servicing Agreement may be amended from time to time by the Depositor, the Master Servicer, the Special Servicer,

of any of the Certificateholders or the Companion Holders:

 

    		A-21-6	 

     

    

 

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

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

 

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

 

		(iv)	to modify, eliminate or add to any provisions of the
Pooling and Servicing Agreement to such extent as shall be necessary to maintain the qualification of any Trust REMIC as a REMIC
or the Grantor Trust as a grantor trust under the relevant provisions of the Code at all times that any Certificate is outstanding,
or to avoid or minimize the risk of imposition of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that
the Trustee and the Certificate Administrator have received an Opinion of Counsel (at the expense of the party requesting such
amendment) to the effect that (a) such action is necessary or desirable to maintain such qualification or to avoid or minimize
the risk of the imposition of any such tax and (b) such action will not adversely affect in any material respect the interests
of any Certificateholder (including, for the avoidance of doubt, any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to modify, eliminate or add to the provisions of Section
5.03(o) of the Pooling and Servicing Agreement or any other provision of the Pooling and Servicing Agreement restricting transfer

of Counsel, cause the Trust, any Trust REMIC or any of the Certificateholders (other than the Transferor) to be subject to a federal
tax caused by a Transfer to a Person that is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to
revise or add any other provisions with respect to matters or questions arising under the Pooling and Servicing Agreement or any

respect the interests of any Certificateholder (including, for the avoidance
of doubt, any Holder of a VRR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to such revision
or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment or as evidenced
by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement and confirmation
of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current
ratings of any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be
considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(vii)	to amend or supplement any provision of the Pooling
and Servicing Agreement to the extent necessary to maintain the then-current ratings assigned to each Class of Certificates by
each Rating Agency, as evidenced by a Rating Agency Confirmation from each of the Rating Agencies and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any class of Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered
satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant
to Section 3.25 of the Pooling and Servicing Agreement); provided that such amendment or supplement shall not adversely
affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt, any Holder of a
VRR Interest) not consenting to such amendment or supplement, as evidenced by an Opinion of Counsel;

 

		(viii)	to
modify the provisions of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable
Advances and Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as
a Control Termination Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded
Loan, as to the Directing Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of
the Controlling Class, the Directing Holder, determine that the commercial mortgage backed securities industry standard for such
provisions has changed, in order to conform to such industry standard, (b) such modification does not adversely affect the status
of any Trust REMIC as a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code,
as evidenced by an Opinion of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to
any class of Serviced Companion Loan Securities, the applicable rating agencies 

 

    		A-21-8	 

     

    

 

have delivered a confirmation that such action will not result in the downgrade, withdrawal or
qualification of its then-current ratings (provided that such rating agency confirmation may be considered satisfied in
the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to Section
3.25 of the Pooling and Servicing Agreement);

 

		(ix)	to modify the procedures of the Pooling and Servicing
Agreement relating to compliance with Rule 17g-5 of the Exchange Act; provided that such amendment shall not adversely
affect in any material respects the interests of any Certificateholders (including, for the avoidance of doubt, any Holders of
a VRR Interest), as evidenced by (x) an Opinion of Counsel or (y) if any Certificate is then rated, receipt of Rating
Agency Confirmation from each Rating Agency rating such Certificates; and provided, further, that the Certificate
Administrator shall give notice of any such amendment to the 17g-5 Information Provider for posting to the 17g-5 Information Provider’s
Website pursuant to Section 3.13(c) of the Pooling and Servicing Agreement and the Certificate Administrator shall post such notice
to the Certificate Administrator’s Website;

 

		(x)	to modify, eliminate or add to any provisions of the
Pooling and Servicing Agreement to such extent as shall be necessary to comply with the requirements for use of Form SF-3 in registered
offerings to the extent provided in CFR 239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions
in the event the Credit Risk Retention Rules or any other regulations applicable to the risk retention requirements for this securitization
transaction are amended or repealed, to the extent required to comply with any such amendment or to modify or eliminate the provision
related to the risk retention requirements in the event of such repeal.

 

Notwithstanding
the foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or
the obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any
Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage
Loan Seller or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The
Pooling and Servicing Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of
Certificates of each Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest
to the extent any such amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not
less than a majority of the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner
the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

 

    		A-21-9	 

     

    

 

		(i)	reduce in any manner the amount of, or delay the timing
of, payments received on the Mortgage Loans that are required to be distributed on a Certificate of any class without the consent
of the Holder of the Certificate or which are required to be distributed to a Companion Holder without the consent of such Companion
Holder; or

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of
Certificates without the consent of the Holders of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage
Loan Purchase Agreement or the obligations of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise
or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without
the consent of such Mortgage Loan Seller; or

 

		(v)	amend the Servicing Standard without the consent of
100% of the Certificateholders or receipt of Rating Agency Confirmation from each Rating Agency and confirmation of the applicable
rating agencies that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings of
any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may be considered satisfied
in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates pursuant to
Section 3.25 of the Pooling and Servicing Agreement) and, if required under the related Intercreditor Agreement, the consent of
the holder of any AB Subordinate Companion Loan for each Serviced AB Whole Loan.

 

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

 

    		A-21-10

may, in that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the
Certificate Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage
Loans (and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following

X-E, Class B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple

 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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C,
Class D, Class E, Class F, Class NR, Class V1-A, Class V1-B, Class V1-D, Class V1-F, Class V1-Z, Class V2-Z, Class R and
Class Z Certificates (together with the Class V1-E Certificates, the “Certificates”; the Holders of
Certificates are collectively referred to herein as “Certificateholders”).

 

This Certificate is
issued pursuant to, and in accordance with, the terms of a Pooling and Servicing Agreement dated as of September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
beneficial ownership of 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,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-E 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 V1-E Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

    	A-22-5 

     

    

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

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

 

    	A-22-6 

     

    

 

Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

Prior to due presentation
of this Certificate for registration of transfer, the Master Servicer, the Special Servicer, the Operating Advisor, the Asset Representations
Reviewer, the Trustee, the Certificate Administrator, the Certificate Registrar, and any agent of the Master Servicer, the Special
Servicer, the Operating Advisor, the Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate
Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class
NR, Class V1-A, Class V1-B, Class V1-D, Class V1-E, Class V1-Z, Class V2-Z, Class R and Class Z Certificates (together with the
Class V1-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 September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
(i) beneficial ownership of multiple “regular interests” 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 and
(ii) a beneficial interest in the Excess Interest and proceeds thereof in the Excess Interest Distribution Account.

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-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 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 V1-F Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

    	A-23-5 

     

    

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

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

 

    	A-23-6 

     

    

 

Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any

and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information
Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing
Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

    	A-23-11 

     

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

    	A-23-12 

     

    

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation

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-5, Class A-SB, Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class

Class V1-Z 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 September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V1-Z 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 V1-Z Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor,

 

    	A-24-4 

     

    

 

if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest

 

    	A-24-5 

     

    

 

therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

Administrator, the Certificate Registrar, or any agent of the Master Servicer, the Special Servicer, the Operating Advisor, the
Asset Representations Reviewer, the Trustee, the Certificate Administrator or the Certificate Registrar shall be affected by any

the Asset Representations Reviewer, the Certificate Administrator and the Trustee, without the consent of any of the Certificateholders
or the Companion Holders:

 

    	A-24-6 

     

    

 

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

which may be inconsistent with any other provisions therein or to correct any error;

or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to

of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have

will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided

or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to revise or add any other provisions with respect to matters or questions arising under the

to maintain the then-current ratings assigned to each Class of Certificates by each Rating Agency, as evidenced by a Rating Agency
Confirmation from each of the Rating Agencies and confirmation of the applicable rating agencies that such action will not result
in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced
by an Opinion of Counsel;

 

		(viii)	to modify the provisions
of Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and
Workout-Delayed Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination
Event has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the
Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed,
in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as
a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion
of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion
Loan Securities, the applicable rating agencies

 

    	A-24-8

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule
17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests
of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates;
and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information
Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing
Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

    	A-24-9 

     

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

    	A-24-10 

     

    

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

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-5, Class A-SB, Class X-A, Class X-B, Class
X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-D, Class V1-E, Class V1-F, Class V1-Z,
Class R and Class Z Certificates (together with the Class V2-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 September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

This Certificate represents
beneficial ownership of multiple “regular interests” 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,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V2-A Certificates
for such Distribution Date, all as more fully described in the Pooling and Servicing Agreement. Holders of this Certificate may
be entitled to Yield Maintenance Charges, as provided in the Pooling and Servicing Agreement.

 

Interest accrued on
this Certificate during an Interest Accrual Period, plus the aggregate unpaid Interest Shortfall with respect to this Certificate,
if any, will be payable on the related Distribution Date to the extent provided in the Pooling and Servicing Agreement. The “Interest
Accrual Period” with respect to any Distribution Date and with respect to the Class V2-A Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

    A-25-5

     

    

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

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

 

    A-25-6

     

    

 

Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein); (vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

 

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

in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);
provided that such amendment or supplement shall not adversely affect in any material respect the interests of any Certificateholder
(including, for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced
by an Opinion of Counsel;

 

		(viii)	to modify the provisions of
Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed
Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event
has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the
Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed,
in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as
a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion
of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion
Loan Securities, the applicable rating agencies

 

    A-25-10

     

    

 

	 	 	have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule
17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests
of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates;
and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information
Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing
Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

    A-25-11

     

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

    A-25-12

     

    

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

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-5, Class A-SB,
Class X-A, Class X-B, Class X-E, Class A-S, Class B, Class C, Class D, Class E, Class F, Class NR, Class V1-A, Class V1-D, Class
V1-E, Class V1-F, Class V1-Z, Class V2-A, Class R and Class Z Certificates (together with the Class V2-Z 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 September 1, 2017 (the “Pooling
and Servicing Agreement”), by and among Credit Suisse Commercial Mortgage Securities Corp., as Depositor, Wells Fargo
Bank, National Association, as Certificate Administrator and as Trustee, Pentalpha Surveillance LLC, as Operating Advisor and as
Asset Representations Reviewer, KeyBank National Association, as Master Servicer, and Rialto Capital Advisors, LLC, as Special
Servicer. To the extent not defined herein, capitalized terms used herein shall have the meanings assigned thereto in the Pooling
and Servicing Agreement.

 

The Certificate Administrator
makes no representation or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates,
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 October 2017 (each such date,
a “Distribution Date”), to the Person in whose name this Certificate is registered as of the related Record
Date, an amount equal to such Person’s pro rata share (based on the Percentage Interest represented by this Certificate)
of that portion of the aggregate amount of principal and interest then distributable, if any, allocable to the Class V2-Z 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 V2-Z Certificates is the calendar
month immediately preceding the month in which such Distribution Date occurs and is assumed to consist of 30 days.

 

All distributions
(other than the final distribution on any Certificate) will be made by the Certificate Administrator to the Persons in whose names
the Certificates are registered at the close of business on each Record Date, which will be the close of business on the last Business
Day of the month immediately preceding the month in which such Distribution Date occurs. Distributions are required to be made
(a) by wire transfer of immediately available funds to the

 

    A-26-4

     

    

 

account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder provided the Certificate Administrator with written wiring instructions no less
than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable
to all subsequent Distribution Dates), or otherwise (b) by check mailed to such Certificateholder at its address in the Certificate
Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such
Certificate at the offices of the Certificate Registrar or such other location specified in the notice to Certificateholders of
such final distribution.

 

Any funds not distributed
to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Certificateholders
to tender their Certificates shall, on such date, be set aside and held uninvested in trust and credited to the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to Section 4.01(h)
of the Pooling and Servicing Agreement shall not have been surrendered for cancellation within six months after the time specified
in such notice, the Certificate Administrator shall mail a second notice to the remaining non tendering Certificateholders to surrender
their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the
second notice all such Certificates shall not have been surrendered for cancellation, the Certificate Administrator, directly or
through an agent, shall take such steps to contact the remaining non tendering Certificateholders concerning the surrender of their
Certificates as it shall deem appropriate and subject to escheatment and other applicable laws. The costs and expenses of holding
such funds in trust and of contacting such Certificateholders following the first anniversary of the delivery of such second notice
to the non-tendering Certificateholders shall be paid out of such funds. No interest shall accrue or be payable to any Certificateholder
on any amount held in trust under the Pooling and Servicing Agreement by the Certificate Administrator as a result of such Certificateholder’s
failure to surrender its Certificate(s) for final payment thereof in accordance with Section 4.01(h) of the Pooling and Servicing
Agreement.

 

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

 

As
provided in the Pooling and Servicing Agreement, the Trust Fund includes: (i) such Mortgage Loans as from time to time are subject
to the Pooling and Servicing Agreement (including any Qualified Substitute Mortgage Loan replacing a removed Mortgage Loan), together
with the Mortgage Files relating thereto (subject to, in the case of a Serviced Whole Loan, the interests of the related Serviced
Companion Noteholder in the related Mortgage File); (ii) all scheduled or unscheduled payments on or collections in respect of
the Mortgage Loans due after the Cut-off Date (or with respect to a Qualified Substitute Mortgage Loan, the Due Date in the month
of substitution); (iii) any REO Property (to the extent of the Trust’s interest therein) or the Trust’s beneficial
interest in the Mortgaged Property securing a Non Serviced Whole Loan acquired under the related Non-Serviced PSA; (iv) all revenues
received in respect of any REO Property (to the extent of the Trust’s interest therein); (v) the Master Servicer’s,
the Special Servicer’s, the Certificate Administrator’s and the Trustee’s rights under the insurance policies
with respect to the Mortgage Loans required to be maintained pursuant to the Pooling and Servicing Agreement and any proceeds thereof
(to the extent of the Trust’s interest therein);

 

    A-26-5

     

    

 

(vi) any Assignment of Leases and any security agreements (to the extent
of the Trust’s interest therein); (vii) any letters of credit, indemnities, guaranties or lease enhancement policies given
as additional security for any related Mortgage Loans (to the extent of the Trust’s interest therein); (viii) all assets
deposited in the Loss of Value Reserve Fund and the Servicing Accounts (to the extent of the Trust’s interest therein), amounts
on deposit in the Collection Account (to the extent of the Trust’s interest therein), the Lower-Tier REMIC Distribution Account,
the Upper-Tier REMIC Distribution Account, the Regular Interest Distribution Account, the Excess Interest Distribution Account,
the Interest Reserve Account, the Gain-on-Sale Reserve Account (to the extent of the Trust’s interest in such Gain-on-Sale
Reserve Account) and any REO Account (to the extent of the Trust’s interest in such REO Account), including any reinvestment
income, as applicable; (ix) any Environmental Indemnity Agreements (to the extent of the Trust’s interest therein); (x) the
rights and remedies of the Depositor under each Mortgage Loan Purchase Agreement (to the extent transferred to the Trustee); (xi)
the Lower-Tier Regular Interests; and (xii) the proceeds of the foregoing (other than any interest earned on deposits in the lock-box
accounts, cash collateral accounts, escrow accounts and any reserve accounts, to the extent such interest belongs to the related
Mortgagor).

 

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

 

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

which may be inconsistent with any other provisions therein or to correct any error;

 

		(iii)	to change the timing and/or nature of deposits in the Collection Account, the Distribution Accounts
or any REO Account; provided that (a) the P&I Advance Date shall in no event be later than the Business Day prior to

of any tax on the Trust or any Trust REMIC or the Grantor Trust; provided that the Trustee and the Certificate Administrator have

or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (b) such action
will not adversely affect in any material respect the interests of any Certificateholder (including, for the avoidance of doubt,
any Holder of a VRR Interest), or Companion Holder;

 

		(v)	to modify, eliminate or add to the provisions of Section 5.03(o) of the Pooling and Servicing Agreement
or any other provision of the Pooling and Servicing Agreement restricting transfer of the Class R Certificates; provided
the Depositor has determined that such change shall not, as evidenced by an Opinion of Counsel, cause the Trust, any Trust REMIC
or any of the Certificateholders (other than the Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is a Disqualified Organization or a Non-U.S. Tax Person;

 

		(vi)	to revise or add any other provisions

in the downgrade, withdrawal or qualification of its then-current ratings of any class of Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

(including, for the avoidance of doubt, any Holder of a VRR Interest) not consenting to such amendment or supplement, as evidenced
by an Opinion of Counsel;

 

		(viii)	to modify the provisions of
Sections 3.05 and 3.17 of the Pooling and Servicing Agreement (with respect to reimbursement of Nonrecoverable Advances and Workout-Delayed
Reimbursement Amounts) if (a) the Depositor, the Master Servicer, the Trustee and, for so long as a Control Termination Event
has not occurred and is not continuing and, with respect to any Mortgage Loans other than any Excluded Loan, as to the Directing
Holder or, if the Directing Holder is the Directing Certificateholder, the Holder of the majority of the Controlling Class, the
Directing Holder, determine that the commercial mortgage backed securities industry standard for such provisions has changed,
in order to conform to such industry standard, (b) such modification does not adversely affect the status of any Trust REMIC as
a REMIC or the status of the Grantor Trust as a grantor trust under the relevant provisions of the Code, as evidenced by an Opinion
of Counsel and (c) each Rating Agency has delivered a Rating Agency Confirmation and, with regard to any class of Serviced Companion
Loan Securities, the applicable rating agencies

 

    A-26-8

     

    

 

	 	 	have delivered a confirmation
that such action will not result in the downgrade, withdrawal or qualification of its then-current ratings (provided that
such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation may be considered
satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement);

 

		(ix)	to modify the procedures of the Pooling and Servicing Agreement relating to compliance with Rule
17g-5 of the Exchange Act; provided that such amendment shall not adversely affect in any material respects the interests
of any Certificateholders (including, for the avoidance of doubt, any Holders of a VRR Interest), as evidenced by (x) an Opinion
of Counsel or (y) if any Certificate is then rated, receipt of Rating Agency Confirmation from each Rating Agency rating such Certificates;
and provided, further, that the Certificate Administrator shall give notice of any such amendment to the 17g-5 Information
Provider for posting to the 17g-5 Information Provider’s Website pursuant to Section 3.13(c) of the Pooling and Servicing
Agreement and the Certificate Administrator shall post such notice to the Certificate Administrator’s Website;

 

		(x)	to modify, eliminate or add to any provisions of the Pooling and Servicing Agreement to such extent
as shall be necessary to comply with the requirements for use of Form SF-3 in registered offerings to the extent provided in CFR
239.45(b)(1)(ii), (iii) or (iv); or

 

		(xi)	to modify, eliminate or add to any of its provisions in the event the Credit Risk Retention Rules
or any other regulations applicable to the risk retention requirements for this securitization transaction are amended or repealed,
to the extent required to comply with any such amendment or to modify or eliminate the provision related to the risk retention
requirements in the event of such repeal.

 

Notwithstanding the
foregoing, no such amendment (A) may change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the
obligations of any Mortgage Loan Seller under any Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage
Loan Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller
or (B) may materially and adversely affect the holders of a Companion Loan without such Companion Holder’s consent.

 

The Pooling and Servicing
Agreement may also be amended from time to time by the parties thereto with the consent of the Holders of Certificates of each
Class affected by such amendment (including, for the avoidance of doubt, any Holders of the VRR Interest to the extent any such
amendment would adversely affect the rights of such Certificateholders) evidencing in the aggregate not less than a majority of
the aggregate Percentage Interests constituting the Class for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders
of Certificates of such Class; provided, however, that no such amendment shall:

 

    A-26-9

     

    

 

		(i)	reduce in any manner the amount of, or delay the timing of, payments received on the Mortgage Loans
that are required to be distributed on a Certificate of any class without the consent of the Holder of the Certificate or which
are required to be distributed to a Companion Holder without the consent of such Companion Holder; or

 

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

 

		(iii)	adversely affect the Voting Rights of any Class of Certificates without the consent of the Holders
of all Certificates of such Class then outstanding; or

 

		(iv)	change in any manner any defined term used in any Mortgage Loan Purchase Agreement or the obligations
of any Mortgage Loan Seller under such Mortgage Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan
Seller as a third party beneficiary under the Pooling and Servicing Agreement, without the consent of such Mortgage Loan Seller;
or

 

		(v)	amend the Servicing Standard without the consent of 100% of the Certificateholders or receipt of
Rating Agency Confirmation from each Rating Agency and confirmation of the applicable rating agencies that such action will not
result in the downgrade, withdrawal or qualification of its then-current ratings of any Serviced Companion Loan Securities, if
any (provided that such rating agency confirmation may be considered satisfied in the same manner as any Rating Agency Confirmation
may be considered satisfied with respect to the Certificates pursuant to Section 3.25 of the Pooling and Servicing Agreement) and,
if required under the related Intercreditor Agreement, the consent of the holder of any AB Subordinate Companion Loan for each
Serviced AB Whole Loan.

 

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

 

    A-26-10

     

    

 

The Holders of the
majority of the Controlling Class, the Special Servicer, the Master Servicer or the Holders of the Class R Certificates may, in
that order of priority, at their option, upon no less than 60 days’ prior written notice given to the Trustee, the Certificate
Administrator and each of the other parties to the Pooling and Servicing Agreement, elect to purchase all of the Mortgage Loans
(and all property acquired through exercise of remedies in respect of any related Mortgage Loan) and the Trust’s portion
of each REO Property remaining in the Trust Fund, and thereby effect termination of the Trust and early retirement of the then-outstanding
Certificates, only on or after the first Distribution Date on which the aggregate Stated Principal Balances of the Mortgage Loans
and the portion of any REO Loans held by the Trust is less than 1.0% of the aggregate Cut-off Date Balance of the Mortgage Loans
as set forth in the Pooling and Servicing Agreement.

 

Following the date
on which the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-SB, Class A-S, Class X-A, Class X-B, Class X-E, Class
B and Class C Regular Interests have been reduced to zero (and provided that there is only one Holder (or multiple Holders
acting in unanimity) of the then-outstanding Certificates (other than the Class Z and Class R Certificates)), the Sole Certificateholder
shall have the right, with the consent of the Master Servicer, to exchange all of its Certificates (other than the Class Z and
Class R Certificates) together with the payment or deemed payment of the Termination Purchase Amount for all of the Mortgage Loans
and each REO Property remaining in the Trust Fund pursuant to the terms of the Pooling and Servicing Agreement.

 

The obligations created
by the Pooling and Servicing Agreement and the Trust created thereby (other than the obligation of the Certificate Administrator
to make payments to Certificateholders as provided for in the Pooling and Servicing Agreement), shall terminate upon reduction
of the Certificate Balances of all the Certificates to zero (including, without limitation, any such final payment resulting from
a termination of the Trust due to a sale of its property) pursuant to the terms of the Pooling and Servicing Agreement. In no event,
however, will the Trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James,
living on the date hereof.

 

Unless the certificate
of authentication hereon has been executed by the Authenticating Agent, by manual signature, this Certificate shall not be entitled
to any benefit under the Pooling and Servicing Agreement or be valid for any purpose. The Certificate Registrar has executed this
Certificate on behalf of the Trust as Certificate Registrar under the Pooling and Servicing Agreement and makes no representation
or warranty as to any of the statements contained herein or the validity or sufficiency of the Certificates or the Mortgage Loans.

 

    A-26-11

     

    

 

IN
WITNESS WHEREOF, the Certificate Administrator has caused this Class V2-Z Certificate to be duly executed.

reimburse the Trust Fund for any costs incurred by it in connection with this transfer.

 

		☐	The
                                         Purchaser is a “qualified institutional buyer” (a “QIB”)
                                         within the meaning of Rule 144A (“Rule 144A”) under the Securities
                                         Act. The Purchaser is aware that the transfer is being made in reliance on Rule 144A,
                                         and the Purchaser has had the opportunity to obtain the information required to be provided
                                         pursuant to paragraph (d)(4)(i) of Rule 144A.

 

2.       The
Purchaser’s intention is to acquire the Certificate (a) for investment for the Purchaser’s own account or (b) for
reoffer, resale, pledge or other transfer (i) to QIBs in transactions under Rule 144A, and not in any event with the view to,
or for resale in connection with, any distribution thereof, or (ii) (other than with respect to any Class R Certificate) to Institutional
Accredited Investors, subject in the case of clause (ii) above to (w) the receipt by the Certificate Registrar of a letter substantially
in the form hereof, (x) the receipt by the Certificate Registrar of an opinion of counsel acceptable to the Trustee and Certificate
Registrar that such reoffer, resale, pledge or transfer is in compliance with the Securities Act, (y) the receipt by the Certificate
Registrar of such other evidence acceptable to the Certificate Registrar that such reoffer, resale, pledge or transfer is in compliance
with the Securities Act and other applicable laws and (z) a written undertaking to reimburse the Trust Fund for any costs incurred
by it in connection with the proposed transfer. The Purchaser understands that the Certificate (and any subsequent 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 reoffer,
resell, pledge or transfer the Certificate only to certain investors in certain exempted transactions) as expressed herein.

 

3.       The
Purchaser has reviewed the Preliminary Prospectus and the Prospectus relating to the Offered Certificates (collectively, the “Prospectus”)
(and, with respect to Offered Private Certificates, the Preliminary Offering Circular and the Final Offering Circular related
to such Offered Private Certificates) and the agreements and other materials referred to therein and has had the opportunity to
ask questions and receive answers concerning the terms and conditions of the transactions contemplated by the Prospectus.

 

4.       The
Purchaser acknowledges that the 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.

 

     Exhibit C-2

     

    

 

5.       The
Purchaser hereby undertakes to be bound by the terms and conditions of the Pooling and Servicing Agreement in its capacity as
an owner of a Certificate or Certificates, as the case may be (each, a “Certificateholder”), in all respects
as if it were a signatory thereto. This undertaking is made for the benefit of the Trust, the Certificate Registrar and all Certificateholders
present and future.

 

6.       The
Purchaser will not sell or otherwise transfer any portion of the Certificate or Certificates, except in compliance with Section
5.03 of the Pooling and Servicing Agreement.

 

7.       Check

	STATE
OF	)

              )          ss.:
	COUNTY OF	)

 

I,
[______], under penalties of perjury, declare that, to the best of my knowledge and belief, the following representations are
true, correct and complete, and being first sworn, depose and say that:

 

1.       I
am a [______] of [______] (the “Purchaser”), on behalf of which I have the authority to make this affidavit.

 

2.       The
Purchaser is acquiring Class R Certificates representing [__]% of the residual interest in each of the real estate mortgage investment
conduits (each, a “REMIC”) designated as the (i) “Lower-Tier REMIC” and (ii) “Upper-Tier
REMIC”, respectively, relating to the Certificates for which an election is to be made under Section 860D of the Internal
Revenue Code of 1986 (the “Code”).

 

3.       The
Purchaser is not a Disqualified Organization (as defined below), and that the Purchaser is not acquiring the Class R Certificates
for the account of, or as agent or nominee of, or with a view to the transfer of direct or indirect record or beneficial ownership
thereof, to a Disqualified Organization. For the purposes hereof, a “Disqualified Organization” is any of the
following: (i) the United States, any State or political subdivision thereof, any 

 

     Exhibit D-1-1

     

    

 

possession of the United States
or any agency or instrumentality of any of the foregoing (other than an instrumentality which is a corporation if all of its activities
are subject to tax and, except for Freddie Mac, a majority of its board of directors is not selected by such governmental unit),
(ii) a foreign government, any international organization or any agency or instrumentality of any of the foregoing, (iii) any
organization which is exempt from the tax imposed by Chapter 1 of the Code (including the tax imposed by Section 511 of the Code
on unrelated business taxable income) on any excess inclusions (as defined in Section 860E(c)(1) of the Code) with respect to
the Class R Certificates (except certain farmers’ cooperatives described in Section 521 of the Code), (iv) rural electric
and telephone cooperatives described in Section 1381(a)(2)(C) of the Code, (v) an “electing large partnership”, as
defined in Section 775 of the Code and (vi) any other Person so designated by the Trustee or the Certificate Administrator based
upon an Opinion of Counsel as provided to the Trustee or the Certificate Administrator (at no expense to the Trustee or the Certificate
Administrator) that the holding of an Ownership Interest in a Class R Certificate by such Person may cause either Trust REMIC
to fail to qualify as a REMIC at any time that the Certificates are outstanding or any Person having an Ownership Interest in
any Class of Certificates (other than such Person) to incur a liability for any federal tax imposed under the Code that would
not otherwise be imposed but for the Transfer of an Ownership Interest in a Class R Certificate to such Person. The terms “United
States,” “State” and “international organization” shall have the meanings set forth in Section 7701
of the Code or successor provisions.

 

4.       The
Purchaser acknowledges that Section 860E(e) of the Code would impose a substantial tax on the transferor or, in certain circumstances,
on an agent for the transferee, with respect to any transfer of any interest in any Class R Certificates to a Disqualified Organization.

 

5.       The
Purchaser is a Permitted Transferee and, to the extent applicable, the Purchaser’s U.S. taxpayer identification number is
[__________].

 

6.       No
purpose of the acquisition of the Class R Certificates is to impede the assessment or collection of tax.

 

7.       The
Purchaser will not cause income from the Class R Certificate to be attributable to a foreign permanent establishment or fixed
base, within the meaning of an applicable income tax treaty, of the Purchaser or any other person.

 

8.       Check
the applicable paragraph: 

 

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

 

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

 

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

 

     Exhibit D-1-2

     

    

  

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

 

For
purposes of this calculation, (i) the Purchaser is assumed to pay tax at the highest rate currently specified in Section 11(b)
of the Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in
Section 11(b) of the Code if the Purchaser has been subject to the alternative minimum tax under Section 55 of the Code
in the preceding two years and will compute its taxable income in the current taxable year using the alternative minimum tax rate)
and (ii) present values are computed using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d)
of the Code for the month of the transfer and the compounding period used by the Purchaser.

 

☐      The
transfer of the Class R Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

 

(i)      the
Purchaser is an “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as
to which income from the Class R Certificate will only be taxed in the United States;

 

(ii)     at
the time of the transfer, and at the close of the Purchaser’s two fiscal years preceding the year of the transfer, the Purchaser
had gross assets for financial reporting purposes (excluding any obligation of a person related to the Purchaser within the meaning
of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;

 

(iii)    the
Purchaser will transfer the Class R Certificate only to another “eligible corporation,” as defined in Treasury Regulations
Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of Sections 1.860E-1(c)(4)(i), (ii) and
(iii) and Treasury Regulations Section 1.860E-1(c)(5); and

 

(iv)    the
Purchaser determined the consideration paid to it to acquire the Class R Certificate based on reasonable market assumptions (including,
but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax
rates and other factors specific to the Purchaser) that it has determined in good faith.

 

☐      None
of the above.

 

9.       The
Purchaser historically has paid its debts as they have come due and intends to pay its debts as they come due in the future and
the Purchaser intends to pay taxes associated with holding the Class R Certificates as they become due.

 

10.     The
Purchaser understands that it may incur tax liabilities with respect to the Class R Certificate in excess of any cash flows generated
by such Certificate.

 

11.    The
Purchaser is aware that the Certificate Registrar will not register any transfer of a Class R Certificate by the Transferor unless
the Purchaser, or such Purchaser’s agent, delivers to the Certificate Registrar, among other things, an affidavit and agreement
in substantially the same form as this affidavit and agreement. The Purchaser expressly agrees that

 

     Exhibit D-1-3

     

    

 

it will not consummate any
such transfer if it knows or believes that any representation contained in such affidavit and agreement is false.

 

12.    The
Purchaser represents that it is not acquiring the Class R Certificate as a nominee, trustee or agent for any person that is not
a Permitted Transferee and that for so long as it retains its interest in the Class R Certificate, it will endeavor to remain
a Permitted Transferee.

 

13.    The
Purchaser consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificate will only be owned, directly or indirectly, by a Permitted Transferee.

 

14.    The
Purchaser has reviewed the provisions of Section 5.03 of the Pooling and Servicing Agreement, a description of which provisions
is set forth in the Class R Certificates; and the Purchaser expressly agrees to be bound by and to comply with such provisions.

 

15.    The
Purchaser consents to the designation of the Certificate Administrator as the agent of the “tax matters person” and
“partnership representative” of each Trust REMIC pursuant to Section 10.01 of the Pooling and Servicing Agreement.

 

Capitalized

Ladies
and Gentlemen:

 

This
letter is delivered to you in connection with the transfer by [______] (the “Transferor”) to [______] (the
“Transferee”) of Class R Certificates evidencing a [__]% Percentage Interest in such Class (the “Residual
Certificates”). The Certificates, including the Residual Certificates, were issued pursuant to the Pooling and Servicing
Agreement, dated as of September 1, 2017 (the “Pooling and Servicing Agreement”), by and among Credit Suisse
Commercial Mortgage Securities Corp., as Depositor, KeyBank National Association, as Master Servicer, Wells Fargo Bank, National
Association, as Certificate Administrator and as Trustee, Rialto Capital Advisors, LLC, as Special Servicer, and Pentalpha Surveillance
LLC, as Asset Representations Reviewer and as Operating Advisor. All capitalized terms used but not otherwise defined herein shall
have the respective meanings set forth in the Pooling and Servicing Agreement. The Transferor hereby certifies, represents and
warrants to you, as Certificate Registrar, that:

 

(1)       No
purpose of the Transferor relating to the transfer of the Residual Certificates by the Transferor to the Transferee is or will
be to impede the assessment or collection of any tax.

 

(2)       The
Transferor understands that the Transferee has delivered to you a Transferee Affidavit and Agreement in the form attached to the
Pooling and Servicing Agreement as Exhibit D-1. The Transferor does not know or believe that any representation contained
therein is false.

 

(3)       The
Transferor has at the time of this transfer conducted a reasonable investigation of the financial condition of the Transferee
as contemplated by Treasury regulation Section 1.860E-1(c)(4)(i) and, as a result of that investigation, the Transferor has determined
that the Transferee has historically paid its debts as they became due and has found no significant evidence to indicate that
the Transferee will not continue to pay its debts as they become due in the future. The Transferor understands that the transfer
of the Residual Certificates may not be

 

     Exhibit D-2-1

     

    

 

respected
for United States income tax purposes (and the Transferor may continue to be liable for United States income taxes associated
therewith) unless the Transferor has conducted such an investigation.

Disclosures

subpoena, civil investigatory demand, request for information or documents, deposition or similar process relating to any legal
proceeding, investigation, hearing or otherwise) to disclose any Confidential Information, you agree to provide the relevant Furnishing
Entity with notice as soon as practicable (except in the case of regulatory or other governmental inquiry, examination or investigation,
and otherwise to the extent practical and permitted by law, regulation or regulatory or other governmental authority) that a request
to disclose the Confidential Information has been made so that the relevant Furnishing Entity may seek an appropriate protective
order or other reasonable assurance that confidential treatment will be accorded the Confidential Information if it so chooses.

with each Furnishing Entity in its efforts to obtain a protective order or other reasonable assurance that confidential treatment
will be accorded to the portion of the Confidential Information that is being disclosed, at the sole expense of such Furnishing
Entity; provided, however, that in no event shall the NRSRO be required to take a position that such information
should be entitled to receive such a protective order or reasonable assurance as to confidential treatment. If a Furnishing Entity
succeeds in obtaining a protective order or other remedy, you agree to comply with its terms with respect to the disclosure of
the Confidential Information, at the sole expense of such Furnishing Entity. If a protective order or other remedy is not obtained
or if the relevant Furnishing Entity waives compliance with the provisions of this Confidentiality Agreement in writing, you agree
to furnish only such information as you are legally required to disclose, at the sole expense of the relevant Furnishing Entity.

document or other material containing Evaluation Material to the extent necessary for legal or regulatory compliance (or compliance
with the NRSRO’s internal policies and procedures designed to ensure legal or regulatory compliance) and (b) the NRSRO may
retain any portion of the Evaluation Material that may be found in backup tapes or other archive or electronic media or other
documents prepared by the NRSRO and any Evaluation Material obtained in an oral communication; provided, that any Evaluation

Furnishing Entity to limit, stop or otherwise remedy such misappropriation, or unauthorized disclosure or use.

 

You
acknowledge and agree that the Furnishing Entities would not have an adequate remedy at law and would be irreparably harmed in
the event that any of the provisions of this Confidentiality Agreement were not performed in accordance with their specific terms
or were otherwise breached. It is accordingly agreed that each Furnishing Entity shall be entitled to specific performance and
injunctive relief to prevent breaches of this Confidentiality Agreement and to specifically enforce the terms and provisions hereof,
in addition to any other remedy to which a Furnishing Entity may be entitled at law or in equity. It is further understood and
agreed that no failure to or delay in exercising any right, power or privilege hereunder shall preclude any other or further exercise

such State.

 

Amendments.

Entity.

 

Entire
Agreement. This Confidentiality Agreement represents the entire agreement between you and the Furnishing Entities
relating to the treatment of Confidential Information heretofore or hereafter reviewed or inspected by you. This agreement supersedes
all other understandings and agreements between us relating to such matters; provided, however, that, if the terms
of this Confidentiality Agreement conflict with another agreement relating to the Confidential Information that specifically states
that the terms of such agreement shall supersede, modify or amend the terms of this Confidentiality Agreement, then to the extent
the terms of this Confidentiality Agreement conflict with such agreement, the terms of such agreement shall control notwithstanding
acceptance by you of the terms hereof by entry into this website.

                                         ____________________

 

    	 	Exhibit U-1	 

     

    

 

Reference
is made to the Pooling and Servicing Agreement described above. Capitalized terms used but not defined herein have the meanings
assigned to such terms in the Pooling and Servicing Agreement.

 

As
Servicer under the Pooling and Servicing Agreement, we hereby:

 

(a)       Notify
you that the Mortgagor has consummated a defeasance of the Mortgage Loan pursuant to the terms of the Mortgage Loan, of the type
checked below:

 

____
a full defeasance of the entire principal balance of the Mortgage Loan; or

 

____
a partial defeasance of a portion of the principal balance of the Mortgage Loan that represents and, an allocated loan amount
of $____________ or _______% of the entire principal balance of the Mortgage Loan;

 

(b)       Certify
that each of the following is true, subject to those exceptions set forth with explanatory notes on Exhibit A hereto, which
exceptions the Master Servicer has determined, consistent with the Servicing Standards, will have no material adverse effect on
the Mortgage Loan or the defeasance transaction:

 

(i)     
   The Mortgage Loan documents permit the defeasance, and the terms and conditions for defeasance specified therein
were satisfied in all material respects in completing the defeasance.

 

(ii)   
    The defeasance was consummated on __________, 20__.

 

(iii)       The
defeasance collateral consists of securities that (i) constitute “government securities” as defined in Section 2(a)(16)
of the Investment Company Act of 1940 as amended (15 U.S.C. 80A1), (ii) are listed as “Qualified Investments for ‘AAA’
Financings” under Paragraphs 1, 2 or 3 of “Cash Flow Approach” in Standard & Poor’s Public Finance
Criteria 2000, as amended to the date of the defeasance, (iii) if they include a principal obligation, the principal due at maturity
cannot vary or change, and (iv) are not subject to prepayment, call or early redemption.

 

(iv)    
  The Master Servicer received an opinion of counsel (from counsel approved by the Servicer in accordance with the Servicing
Standard) that the defeasance will not result in an Adverse REMIC Event.

 

(v)     
  The Master Servicer determined that the defeasance collateral will be owned by an entity (the “Defeasance
Obligor”) that is a Single-Purpose Entity (as defined in Standard & Poor’s Structured Finance Ratings Real
Estate Finance Criteria, as amended to the date of the defeasance (the “S&P Criteria”)) or is subject to
restrictions in its organizational documents substantially similar to those contained in the organization documents of the original
Borrower with respect to bankruptcy remoteness and single purpose as of the date of the defeasance, and after the defeasance owns
no assets other than the defeasance collateral and real property securing Mortgage Loans included in the pool.

 

    	 	Exhibit U-2	 

     

    

 

(vi)       The
defeasance documents require the crediting of the defeasance collateral to an Eligible Account (as defined in the S&P Criteria)
in the name of the Trustee on behalf of the Trust, which account is maintained as a securities account by a securities intermediary
and has been pledged to the Trustee on behalf of the Trust.

 

(vii)      The
agreements executed in connection with the defeasance (i) grant control of the pledged securities account to Trustee on behalf
of the Trust, (ii) require the securities intermediary to make the scheduled payments on the Mortgage Loan from the proceeds of
the defeasance collateral directly to the Master Servicer’s collection account in the amounts and on the dates specified
in the Mortgage Loan documents or, in a partial defeasance, the portion of such scheduled payments attributed to the allocated
loan amount for the real property defeased, increased by any defeasance premium specified in the Mortgage Loan documents (the
“Scheduled Payments”), (iii) permit reinvestment of proceeds of the defeasance collateral only in Permitted
Investments (as defined in the Pooling and Servicing Agreement or as defined in the documents evidencing the defeasance), (iv)
permit release of surplus defeasance collateral and earnings on reinvestment from the pledged securities account only after the
Mortgage Loan has been paid in full, if any such release is permitted, (v) prohibit transfers by the Defeasance Obligor of the
defeasance collateral and subordinate liens against the defeasance collateral, and (vi) provide for payment from sources other
than the defeasance collateral or other assets of the Defeasance Obligor of all fees and expenses of the securities intermediary
for administering the defeasance and the securities account and all fees and expenses of maintaining the existence of the Defeasance
Obligor.

 

(viii)     The
Master Servicer received written confirmation from a firm of independent certified public accountants, who were approved by the
Master Servicer in accordance with the Servicing Standard stating that (i) revenues from the defeasance collateral (without taking
into account any earnings on reinvestment of such revenues) will be sufficient to timely pay each of the Scheduled Payments after
the defeasance including the payment in full of the Mortgage Loan (or the allocated portion thereof in connection with a partial
defeasance) on its Maturity Date (or, in the case of an ARD Loan, on its Anticipated Repayment Date), (ii) the revenues received
in any month from the defeasance collateral will be applied to make Scheduled Payments within four (4) months after the date of
receipt, and (iii) interest income from the defeasance collateral to the Defeasance Obligor in any calendar or fiscal year will
not exceed such Defeasance Obligor’s interest expense for the Mortgage Loan (or the allocated portion thereof in a partial
defeasance) for such year.

 

(ix) 
     The Mortgage Loan is not among the ten (10) largest loans in the pool as of the date of the Current
Report (as defined below). The entire principal balance of the Mortgage Loan as of the date of defeasance was less than both $[______]
and five percent of pool balance, which is less than [__]% of the aggregate Certificate Balance of the Certificates as of the
date of the most recent Distribution Date Statement received by us (the “Current Report”).

 

    	 	Exhibit U-3	 

     

    

 

(x)   
    The Master Servicer has received opinions of counsel stating that the Trustee on behalf of the Trust possesses
a valid, perfected first priority security interest in the defeasance collateral and that the documents executed in connection
with the defeasance are enforceable in accordance with their respective terms.

 

(c)       
Certify that Exhibit B hereto is a list of the material agreements, instruments, organizational documents for the Defeasance
Obligor, and opinions of counsel and independent accountants executed and delivered in connection with the defeasance.

 

(d)        Certify
that the individual under whose hand the Master Servicer has caused this Notice and Certification to be executed did constitute
a Servicing Officer as of the date of the defeasance described above.

 

(e)        Agree
to provide copies of all items listed in Exhibit B to you upon request.

IN
WITNESS WHEREOF, the Master Servicer has caused this Notice and Certification to be executed as of the date captioned above.

                                         Advisor participated in discussions and made strategic observations and recommended alternative

    	 	Exhibit V-2	 

     

    

 

NOTE:
The Operating Advisor’s review of the above materials should be considered a limited investigation and not be considered
a full or limited audit, legal review or legal opinion. For instance, we did not review each page of the Special Servicer’s
policy and procedure manuals (including amendments and appendices), review underlying lease agreements or similar underlying documents,
re-engineer the quantitative aspects of their net present value calculation, visit any related property, visit the Special Servicer,
visit the Directing Certificateholder or interact with any borrower. In addition, our review of the net present value calculations,
Collateral Deficiency Amount Calculations and Appraisal Reduction calculations and the corresponding application of the non-discretionary
portions of the applicable formulas, and as such, does not take into account the reasonableness of the discretionary portions
of such formulas.

                                         participate in, or have access to, the Special Servicer’s and Directing Certificateholder’s
                                         discussion(s) regarding any Specially Serviced Loan. The Operating Advisor does not have
                                         authority to speak with the Directing Certificateholder or borrower directly. As such,
                                         the Operating Advisor relied upon the information delivered to it by the Special Servicer
                                         as well as its interaction with the Special Servicer, if any, in gathering the relevant
                                         information to generate this report. The services that we perform are not designed and
                                         cannot be relied upon to detect fraud or illegal acts should any exist.

 

		4.	The
                                         Special Servicer has the legal authority and responsibility to service any Specially
                                         Serviced Loans pursuant to the Pooling and Servicing Agreement. The Operating Advisor
                                         has no responsibility or authority to alter the standards set forth therein or the actions
                                         of the Special Servicer.

 

		5.	Confidentiality
                                         and other contractual limitations limit the Operating Advisor’s ability to outline
                                         the details or substance of any communication held between it and the Special Servicer
                                         regarding any Specially Serviced Loans and certain information it reviewed in connection
                                         with its duties under the Pooling and Servicing Agreement. As a result, this report may
                                         not reflect all the relevant information that the Operating Advisor is given access to
                                         by the Special Servicer.

 

		6.	The
                                         Operating Advisor is not empowered to speak with any investors directly. If the investors
                                         have questions regarding this report, they should address such questions to the certificate
                                         administrator through the certificate administrator’s website.

 

		7.	This
                                         report does not constitute recommendations to buy, sell or hold any security, nor does
                                         the Operating Advisor take into account market prices of securities or financial markets
                                         generally when performing its limited review of the Special Servicer as described above.
                                         The Operating Advisor does not have a fiduciary relationship with any Certificateholder
                                         or any other party or individual. Nothing is intended to or should be construed as creating
                                         a fiduciary relationship between the Operating Advisor and any Certificateholder, party
                                         or individual.

Ladies
and Gentlemen:

 

Reference
is hereby made to that certain Pooling and Servicing Agreement dated as of September 1, 2017 (the “Pooling and Servicing
Agreement”), among the Credit Suisse Commercial Mortgage Securities Corp., as Depositor, KeyBank National Association,
as Master Servicer, Rialto Capital Advisors, LLC, as Special Servicer, Wells Fargo Bank, National Association, as Certificate
Administrator and as Trustee, and Pentalpha Surveillance LLC, as Asset Representations Reviewer and as Operating Advisor. Defined
terms used herein and not otherwise defined shall have the meanings set forth in the Pooling and Servicing Agreement.

 

KeyBank
National Association (“KeyBank”)/Rialto Capital Advisors, LLC (“Rialto”) understands that
[____] (the “Company”) is requesting certain confidential or non-public information relating to the Mortgage
Loans to which the Company has continuing rights as a

 

    	 	Exhibit X-1	 

     

    

 

[_____] [__], 20[__]

Page 2

 

Certificateholder.
The Company is requesting such information for the purpose of analyzing asset performance and evaluating any continuing rights
the Company may have under the Trust (the “Permitted Purpose”). The Company agrees that the Permitted Purpose
shall not include the use or disclosure of the Confidential Information (as defined below) in any manner that violates any applicable
law, the Pooling and Servicing Agreement or the related mortgage loan documents.

 

KeyBank/Rialto
will provide the Company with certain confidential, non-public servicing information (the “Confidential Information”)
pertaining to the Mortgage Loans and the related Mortgaged Properties and borrowers. The Company acknowledges that the Confidential
Information (a) includes or may be based upon information provided to KeyBank/Rialto by third parties, (b) may not have been verified
by KeyBank/Rialto, and (c) may be incomplete or contain inaccuracies. The Company agrees that KeyBank/Rialto, the [“Master
Servicer”/”Special Servicer”] (as defined in the Pooling and Servicing Agreement) and their respective
Representatives (as defined below) shall not have any liability to the Company or its Representatives resulting from (x) any inaccuracies
or omissions in the Confidential Information, (y) any use of the Confidential Information, or (z) KeyBank/Rialto’s failure
or inability to provide the Confidential Information to the Company for any reason. Notwithstanding the foregoing, the following
will not constitute “Confidential Information” for purposes of this letter agreement: (a) information that
was already in Company’s possession prior to its receipt from KeyBank/Rialto; (b) information that is obtained by Company
from a third person who, insofar as is known to Company, is not prohibited from transmitting the information to Company by a contractual,
legal or fiduciary obligation to KeyBank/Rialto; (c) information that is or becomes publicly available through no fault of Company;
and (d) information that is independently developed by Company. The term “Representatives” with respect to any entity
shall mean the officers, directors, general partners, employees, agents, affiliates, auditors and legal counsel (which may be
internal counsel) of that entity.

 

The
Company may have access to the Confidential Information through (at KeyBank/Rialto’s election): (i) responses to reasonable
written inquiries received from the Company, (ii) conference calls conducted on a reasonably scheduled basis with KeyBank/Rialto’s
surveillance group, or (iii) direct on-line access (read-only capacity) to the information available on the applicable [____]
system or any successor or replacement system (“System”). KeyBank/Rialto may cease or defer providing the Company
with Confidential Information in the event that (a) the Company or its Representatives violate any provision hereof, or (b) KeyBank/Rialto
determines (in its sole discretion) that such termination is necessary for any reason, including its determination that such action
is required pursuant to the terms of the Pooling and Servicing Agreement, the related Mortgage Loan documents, or any applicable
law. KeyBank/Rialto shall cease to provide the Company with Confidential Information if KeyBank/Rialto has actual knowledge that
the Company or its Representatives are affiliates of any borrower under the Mortgage Loan documents and KeyBank/Rialto determines
that the provision, notice or access to such Confidential Information would violate the accepted servicing practices or servicing
standards as defined in the Pooling and Servicing Agreement. The Company’s obligations and the restrictions applicable to
the protection of the Confidential Information hereunder shall survive the termination of the Company’s access to the Confidential
Information. KeyBank/Rialto’s remedies hereunder, at law or at equity, are cumulative and may be combined.

The
Company agrees that it will not, and it shall not permit its Representatives, to disclose the Confidential Information in any
manner whatsoever to any other person or entity, other than its Representatives (but only to the extent necessary to accomplish
the Permitted Purpose) who have a need to know the information, or as otherwise required by applicable law, court order or any
governmental agency or regulator. The Company acknowledges (i) its obligations under the U.S. federal securities laws, and (ii)
that any disclosure of the Confidential Information by it or its Representatives for any purpose other than a Permitted Purpose,
in addition to being a breach of this letter agreement, may constitute a violation of federal and state securities laws. The Company
will take reasonable measures to ensure that each Representative is advised of this letter agreement and agrees to keep the Confidential
Information confidential. The Company shall be liable for any breach of this letter agreement by its Representatives. Notwithstanding
the foregoing, the Company may subsequently provide all or any part of such Confidential Information to any other person or entity
that holds or is contemplating the purchase of any Certificate or interest therein, but only if such person or entity confirms
such ownership interest or prospective ownership interest and provided that, prior to the delivery of such Confidential
Information, such persons shall have executed and delivered to the Company an agreement that is substantially similar in form
and substance to this Agreement.

 

This
letter agreement shall be governed by and construed in accordance with the laws of the State of New York without the application
of conflict of laws principles. Anything herein to the contrary notwithstanding, KeyBank/Rialto intends at all times to comply
with the terms and provisions of the Pooling and Servicing Agreement and nothing in this letter agreement should be construed
to limit or qualify any of KeyBank/Rialto’s rights or obligations under the Pooling and Servicing Agreement. This letter
agreement may be executed in counterparts and by facsimile/Portable Document Format (PDF); each such counterpart shall be deemed
to be an original instrument, and all such counterparts together shall constitute one agreement.

 

This
agreement shall terminate with respect to the information received by the Company one year after the Company receives such information
or ceases to be a Certificateholder. Company agrees that this letter agreement supersedes and replaces and survives any click-through
agreement regarding confidentiality of Confidential Information agreed to in connection with accessing the System whether agreed
to in accessing the System before or after signing this letter agreement.

ASSET
REVIEW PROCEDURES

 

Pursuant
to the terms and subject to the conditions set forth in the Pooling and Servicing Agreement (“PSA”), the Asset
Representations Reviewer (“Asset Representations Reviewer”) shall perform an Asset Review with respect to each
representation and warranty made by the related Mortgage Loan Seller only with respect to each Delinquent Loan in accordance with
the procedures set forth below (each such procedure, a “Test”); provided, however, the Asset
Representations Reviewer may, but is under no obligation to, modify any Test and/or associated Review Materials described in this
Exhibit QQ if, and only to the extent, the Asset Representations Reviewer determines pursuant to the Asset Review Standard
that it is necessary to modify such Test and/or such associated Review Materials in order to facilitate its Asset Review in accordance
with the Asset Review Standard. Capitalized terms used herein but not defined herein have the meaning set forth in the PSA or,
solely with respect to a representation and warranty, the meaning set forth in the related mortgage loan purchase agreement (the
“MLPA”). For the avoidance of doubt, in connection with the performance of the following Tests:

 

		(A)	With
                                         respect to any representation and warranty that includes a knowledge qualifier (e.g.,
                                         to the Mortgage Loan Seller’s knowledge, etc.), the Asset Representations Reviewer
                                         shall not be responsible for any investigation or review beyond that set forth in the
                                         applicable Test related to such representation and warranty;

 

		(B)	With
                                         respect to any representation and warranty that includes the examination of an insurance
                                         policy or Title Policy, the Asset Representations Reviewer will be permitted to engage
                                         a qualified consultant to perform a review of the applicable policy, and will be allowed
                                         to rely upon the conclusions of the consultant when making a determination as to whether
                                         there is a Test pass.

 

		(C)	The
                                         Asset Representations Reviewer shall be under no duty to provide or obtain a legal opinion,
                                         legal review or legal conclusion;

 

		(D)	Unless
                                         otherwise provided in the Test, the “as of” date for the testing of a representation
                                         is as of the Closing Date;

 

		(E)	Unless
                                         otherwise provided in the Test, if there is more than one version of the same document
                                         with respect to a particular Mortgage Loan or Mortgaged Property, the document that will
                                         be used by the Asset Representations Reviewer in testing is the document that is dated
                                         as of the Closing Date or, if none, the document closest prior to the Closing Date;

 

		(F)	With
                                         respect to each representation and warranty and its related Test(s), the Asset Representations
                                         Reviewer shall take into account any exceptions to such representation and warranty described
                                         in the Mortgage Loan Purchase Agreement with respect to a Mortgage Loan, and a Test pass
                                         shall be deemed to have occurred with respect to such

 

     Exhibit QQ-1

     

    

 

Test
if the sole reason for not satisfying the applicable Test is caused by such exception(s);

 

		(G)	Evidence
                                         of a failure of a Test could result from (i) an affirmative determination by the Asset
                                         Representations Reviewer that the Test failed to achieve a Test pass, or (ii) a determination
                                         by the Asset Representations Reviewer that the documentation included in the Review Materials
                                         (after making such request for any missing documents in the manner provided for in the
                                         PSA) is not sufficient to perform the Test; and

 

		(H)	A
                                         determination by the Asset Representations Reviewer of a Test pass or a Test failure
                                         shall not constitute a determination by the Asset Representations Reviewer of (i) the
                                         existence or nonexistence of a Material Defect, or (ii) whether the Trust should enforce
                                         any rights it may have against the applicable Mortgage Loan Seller.

 

The
Asset Representations Reviewer will only be required to perform the Tests described in this Exhibit QQ, and will not be
obligated to perform additional procedures on any Delinquent Loan, even if a different set of procedures or Review Materials could
produce a different outcome. Notwithstanding the required Tests, the Asset Representations Reviewer will not be required to review
any information other than (1) Review Materials specified in the related Test and (2) if applicable, Unsolicited Information.
The Asset Representations Reviewer may, but is under no obligation to, consider Unsolicited Information relevant to the Tests
subject to the terms of the PSA. If the Asset Representations Reviewer considers Unsolicited Information, the Asset Representations
Reviewer shall take into account such Unsolicited Information, in addition to the Review Materials referred to in the applicable
Test(s) procedure when making a determination as to whether there is a Test pass.

                                         part of a Whole Loan, each Mortgage Loan is a whole loan and not an interest in a mortgage
                                         loan. Each Mortgage Loan is a senior portion (or a pari passu portion of a senior portion)

                                         marketable title to, and was the sole owner of, each Mortgage Loan free and clear of
                                         any and all liens, charges, pledges, encumbrances, participations (other than with respect

                                         to be, insured by a property insurance policy providing coverage for loss in accordance
                                         with coverage found under a “special cause of loss form” or “all-risk
                                         form” that includes replacement cost valuation issued by an insurer meeting the
                                         requirements of the related Mortgage Loan documents and having a claims-paying or financial
                                         strength rating of at least “A-:VIII” (for a Mortgage Loan with a principal
                                         balance below $35 million) and “A:VIII” (for a Mortgage Loan with a principal
                                         balance of $35 million or more) from A.M. Best Company or “A3” (or the equivalent)
                                         from Moody’s Investors Service, Inc. or “A-” from S&P Global Ratings
                                         (collectively the “Insurance Rating Requirements”), in an amount not less
                                         than the lesser of (1) the original principal balance of the Mortgage Loan and (2) the
                                         full insurable value on a replacement cost basis of the improvements, furniture, furnishings,

                                         (with no deduction for physical depreciation), but, in any event, not less than the amount
                                         necessary or containing such endorsements as are necessary to avoid the operation of
                                         any coinsurance provisions with respect to the related Mortgaged Property.

         

        Each
        related Mortgaged Property is also covered, and required to be covered pursuant to the related Mortgage Loan documents,
        by business interruption or rental loss insurance which (i) covers a period of not less than 12 months (or with respect
        to each Mortgage Loan with a principal balance of $35 million or more, 18 months); (ii) for a Mortgage Loan with a principal
        balance of $50 million or more contains a 180-day “extended period of indemnity”; and (iii) covers the actual
        loss sustained during restoration.

         

        If
        any material part of the improvements, exclusive of a parking lot, located on a Mortgaged Property is in an area identified
        in the Federal Register by the Federal Emergency Management Agency as having special flood hazards, the related Mortgagor
        is required to maintain insurance in the maximum amount available under the National Flood Insurance Program, plus such
        additional excess flood coverage in an amount as is generally required by the mortgage loan seller originating mortgage
        loans for securitization.

        The

        An

        zones 3 or 4 in order to evaluate the structural and seismic condition of such property, for the sole purpose of assessing
        the probable maximum loss (“PML”) for the Mortgaged Property in the event of an earthquake. In such
        instance, the PML or equivalent was based on a 475-year return period, an exposure period of 50 years and a 10% probability
        of exceedance. If the resulting report concluded that the PML or equivalent would exceed 20% of the amount of the replacement
        costs of the improvements, earthquake insurance on such Mortgaged Property was obtained by an insurer rated at least “A:VIII”
        by A.M. Best Company or “A3” (or the equivalent) from Moody’s Investors Service, Inc. or “A-”

        premiums on all insurance policies referred to in this section required to be paid as of the Cut-off Date have been paid,
        and such insurance policies name the lender under the Mortgage Loan and its successors and assigns as a loss payee under
        a mortgagee endorsement clause or, in the case of the general liability insurance policy, as named or additional insured.
        Such insurance policies will inure to the benefit of the trustee or the Non-Serviced Trustee for Non-Serviced Mortgage
        Loans. Each related Mortgage Loan obligates the related Mortgagor to maintain all such insurance and, at such Mortgagor’s
        failure to do so, authorizes the lender to maintain such insurance at the Mortgagor’s cost and expense and to charge
        such Mortgagor for related premiums. All such insurance policies (other than commercial liability policies) require at
        least 10 days’ prior notice to the lender of termination or cancellation arising because of nonpayment of a premium
        and at least 30 days prior notice to the lender of termination or cancellation (or such lesser period, not less than 10
        days, as may be required by applicable law) arising for any reason other than non-payment of a premium and no such notice
        has been received by the mortgage loan seller.

                                         Entity. Each Mortgage Loan requires the Mortgagor to be a Single-Purpose Entity for
                                         at least as long as the Mortgage Loan is outstanding. Both the Mortgage Loan documents
                                         and the organizational documents of the Mortgagor with respect to each Mortgage Loan
                                         with a Cut-off Date Balance in excess of $5 million provide that the Mortgagor is a Single-Purpose
                                         Entity, and each Mortgage Loan with a Cut-off Date Balance of $20 million or more has
                                         a counsel’s opinion regarding non-consolidation of the Mortgagor. For this purpose,
                                         a “Single-Purpose Entity” shall mean an entity, other than an individual,

                                         Loans and prohibit it from engaging in any business unrelated to such Mortgaged Property
                                         or Properties, and whose organizational documents further provide, or which entity represented

                                         can be defeased (a “Defeasance”), (i) the Mortgage Loan documents

                                         of real property in connection with partial defeasance, the revenues from the collateral
                                         will be sufficient to pay all such scheduled payments calculated on a principal amount
                                         equal to a specified percentage at least equal to 115% of the allocated loan amount for
                                         the real property to be released; (iv) the defeasance collateral is not permitted to
                                         be subject to prepayment, call, or early redemption; (v) the Mortgagor is required to
                                         provide a certification from an independent certified public accountant that the collateral
                                         is sufficient to make all scheduled payments under the Mortgage Note as set forth in
                                         (iii) above, (vi) if the Mortgagor would continue to own assets in addition to the defeasance
                                         collateral, the portion of the Mortgage Loan secured by defeasance collateral is required
                                         to be assumed (or the Mortgagee may require such assumption) by a Single-Purpose Entity;
                                         (vii) the Mortgagor is required to provide an opinion of counsel that the Mortgagee has
                                         a perfected security interest in such collateral prior to any other claim or interest;
                                         and (viii) the Mortgagor is required to pay all rating agency fees associated with defeasance
                                         (if rating confirmation is a specific condition precedent thereto) and all other reasonable

                                         Interest Rates. Each Mortgage Loan bears interest at a rate that remains fixed throughout

                                         where default interest is imposed.

	36.  Ground
                                         Leases.   For purposes of the MLPA, a “Ground Lease”
                                         shall mean a leasehold estate in real property where the fee owner as the ground
                                         lessor conveys for a term or terms of years its entire interest in the land and buildings
                                         and other improvements, if any, to the ground lessee (who may, in certain circumstances,
                                         own the building and improvements on the land), subject to the reversionary interest
                                         of the ground lessor as fee owner.

         

        With
        respect to any Mortgage Loan where the Mortgage Loan is secured by a ground leasehold estate in whole or in part, and
        the related Mortgage does not also encumber the related lessor’s fee interest in such Mortgaged Property, based
        upon the terms of the ground lease and any estoppel or other agreement received from the ground lessor in favor of the
        mortgage loan seller, its successors and assigns:

         

        (A)  The
        ground lease or a memorandum regarding such ground lease has been duly recorded or submitted for recordation in a form
        that is acceptable for recording in the applicable jurisdiction. The ground lease or an estoppel or other agreement received
        from the ground lessor permits the interest of the lessee to be encumbered by the related Mortgage and does not restrict
        the use of the related Mortgaged Property by such lessee, its successors or assigns in a manner that would adversely affect
        the security provided by the related Mortgage. To the mortgage loan seller’s knowledge, no material change in the
        terms of the ground lease had occurred since its recordation, except by any written instruments which are included in
        the related Mortgage File;

         

        (B)  The
        lessor under such ground lease has agreed in a writing included in the related Mortgage File (or in such ground lease)
        that the ground lease may not be amended, modified, canceled or terminated without the prior written consent of the lender
        and that any such action without such consent is not binding on the lender, its successors or assigns;

         

        (C)  The
        ground lease has an original term (or an original term plus one or more optional renewal terms, which, under all

                                         maturity (or with respect to a Mortgage Loan that accrues on an actual 360 basis, substantially

        Mortgage, except for the related fee interest of the ground lessor and the Permitted Encumbrances;

         

        (E)  The
        ground lease does not place commercially unreasonable restrictions on the identity of the mortgagee and the ground lease
        is assignable to the holder of the Mortgage Loan and its successors and assigns without the consent of the lessor thereunder,
        and in the event it is so assigned, it is further assignable by the holder of the Mortgage Loan and its successors and
        assigns without the consent of the lessor;

         

        (F)  The
        mortgage loan seller has not received any written notice of default under or notice of termination of such ground lease.
        To the mortgage loan seller’s knowledge, there is no default under such ground lease and no condition that, but
        for the passage of time or giving of notice, would result in a default under the terms of such ground lease and, to the
        mortgage loan seller’s knowledge, such ground lease is in full force and effect as of the

        Closing
        Date;

         

        (G)  The
        ground lease or ancillary agreement between the lessor and the lessee requires the lessor to give to the lender written
        notice of any default, provides that no notice of default or termination is effective unless such notice is given to the
        lender, and requires that the ground lessor will supply an estoppel;

         

        (H)
        A lender is permitted a reasonable opportunity (including, where necessary, sufficient time to gain possession of the
        interest of the lessee under the ground lease through legal proceedings) to cure any default under the ground lease which

        loan seller in connection with loans originated for securitization;

        and the related Mortgage (taken together), any related insurance proceeds, or portion of the condemnation award allocable

        Property to the extent not applied to restoration, will be applied first to the payment of the outstanding principal balance
        of the Mortgage Loan, together with any accrued interest; and

         

        (L)  Provided
        that the lender cures any defaults which are susceptible to being cured, the ground lessor has agreed to enter into a
        new lease with lender upon termination of the ground lease for any reason, including rejection of the ground lease in

                                         Loan. Each Mortgage Loan identified in the Mortgage Loan Schedule as an ARD Loan
                                         starts to amortize no later than the Due Date of the calendar month immediately after
                                         the calendar month in which such ARD Loan closed and substantially fully amortizes over
                                         its stated term, which term is at least 60 months after the related Anticipated Repayment
                                         Date. Each ARD Loan has an Anticipated Repayment Date not less than five years following
                                         the origination of such Mortgage Loan. If the related Mortgagor elects not to prepay
                                         its ARD Loan in full on or prior to the Anticipated Repayment Date pursuant to the existing

                                         under Code Section 1001) in the Mortgage Loan exercisable during the term of the Mortgage
                                         Loan, (i) the Mortgage Loan’s interest rate will step up to an interest rate per
                                         annum as specified in the related Mortgage Loan documents; provided, however,
                                         that payment of such Excess Interest shall be deferred until the principal of such ARD
                                         Loan has been paid in full; (ii) all or a substantial portion of the excess cash flow
                                         (which is net of certain costs associated with owning, managing and operating the related
                                         Mortgaged Property) collected after the Anticipated Repayment Date shall be applied towards

                                         reduced to zero all excess cash flow will be applied to the payment of accrued Excess
                                         Interest; and (iii) if the property manager for the related Mortgaged Property can be
                                         removed by or at the direction of the mortgagee on the basis of a debt service coverage

                                         Repayment Date. No ARD Loan provides that the property manager for the related Mortgaged

        insurance policy, issued by the issuer set forth on Schedule I (the “Policy Issuer”) and effective as of the
        date thereof (the “Environmental Insurance Policy”), (ii) as of the date of origination of the Mortgage Loan
        and to the mortgage loan seller’s knowledge as of the Cut-off Date the Environmental Insurance Policy is in full

        3.  If
        the determination in subpart 1 cannot be made and the determination in subpart 2 cannot be made or such subpart is not
        applicable, review the Diligence File to determine if any Environmental Condition identified was remediated or abated
        in all material respects prior to the Cut-off Date, or that a no further action or closure letter was obtained from the
        applicable governmental regulatory authority (or to determine if the environmental issue affecting the Mortgaged Property
        was otherwise listed by such governmental authority as administratively “closed” or a reputable environmental
        consultant has concluded that no further action is required).

         

        4.  If
        the determinations in subparts 1 and 3 cannot be made and the determination in subpart 2 cannot be made or such subpart
        is not applicable, review the Diligence File to determine if there exists an environmental policy or a lender’s
        pollution legal liability insurance policy meeting the requirements set forth below that covers liability for the identified
        circumstance or condition was obtained from an insurer rated no less than A- (or the equivalent) by Moody’s Investors
        Service, Inc., S&P Global Ratings and/or Fitch Ratings, Inc.

         

        5.  If
        the determinations in subparts 1, 3 and 4 cannot be made and the determination in subpart 2 cannot be made or such subpart
        is not applicable, review the Diligence File to determine if a party with assets reasonably estimated to be adequate to
        effect all necessary remediation was identified as the responsible party for such condition or circumstance.
