a downgrade, qualification or withdrawal of the applicable rating or ratings ascribed by such Rating Agency to any of the Certificates
then outstanding. In the event that no Certificates are outstanding or none of the Notes are included in a Securitization, any
action that would otherwise require a Rating Agency Confirmation shall require the consent of the Note A-1 Holder, which
consent shall not be unreasonably withheld, conditioned or delayed.


 


For
the purposes of this Agreement, if any Rating Agency (1) waives, declines or refuses, in writing to review or otherwise engage
any request for a confirmation hereunder from such Rating Agency that a proposed action will not result in a qualification, downgrade
or withdrawal of its then current rating of the securities issued pursuant to the related Securitization, or (2) does not reply
to such request or responds in a manner that indicates that such Rating Agency is neither reviewing such request nor waiving the
requirement for Rating Agency Confirmation and the related timing, notice and other applicable provisions set forth in the Servicing
Agreement and the Non-Lead Servicing Agreement, as applicable, have been satisfied, then for such request only, the condition
that such confirmation by such Rating Agency (only) be obtained will be deemed not to apply for purposes of this Agreement. For
purposes of clarity, any such waiver, declination or refusal to review or otherwise engage in any request for such confirmation
hereunder shall not be deemed a waiver, declination or refusal to review or otherwise engage in any subsequent request for such
Rating Agency Confirmation hereunder and the condition for such Rating Agency Confirmation pursuant to this Agreement for any
subsequent request shall apply regardless of any previous waiver, declination or refusal to review or otherwise engage in such
prior request.

of the Mortgage Loan. (a)  Each Holder acknowledges and agrees that, subject in each case to the specific terms
of this Agreement, the Mortgage Loan shall be serviced as follows:


 


(i)        from
and after the UBS 2017-C5 Securitization Date, but prior to the Note A-1 Securitization Date, by the UBS 2017-C5 Master Servicer
and the UBS 2017-C5 Special Servicer pursuant to the terms of this Agreement and the UBS 2017-C5 PSA; and

to the terms of this Agreement and the Note A-1 PSA.


 


Each Holder agrees to
reasonably cooperate with each Servicer with respect to its exercise of its rights and obligations under the Servicing Agreement.


 


(b)       The

assets similar to the Mortgage Loan and that are otherwise (i) required by the Code relating to the tax elections of the Note A-1
Trust Fund and the UBS 2017-C5 Trust Fund, (ii) required by law or changes in any law, rule or regulation or (iii) requested
by the Rating Agencies rating the Note A-1 Securitization or the UBS 2017-C5 Securitization. In addition, the Note A-1 PSA

to the terms and conditions of this Agreement, each Holder hereby irrevocably and unconditionally consents to the appointment of
the Master Servicer and the Trustee under the Servicing Agreement by the Depositor and the appointment of the Special Servicer
by the Directing Holder and agrees to reasonably cooperate with the Master Servicer and the Special Servicer with respect to the
servicing of the Mortgage Loan in accordance with the Servicing Agreement. Each Holder hereby appoints the Master Servicer, the
Special Servicer and the Trustee under the Servicing Agreement as such Holder’s attorney-in-fact to sign any documents reasonably
required with respect to the administration and servicing of the Mortgage Loan on its behalf under the Servicing Agreement (subject
at all times to the rights of the Holders as set forth herein and in such Servicing Agreement).


 


(d)       If,
at any time the Lead Note is no longer in a Securitization, the Note A-1 Holder shall cause the Mortgage Loan to be serviced
pursuant to a servicing agreement that is substantially similar to the Servicing Agreement (and, if the Non-Lead Note is in a Securitization,
subject to receipt of a Rating Agency Confirmation from the Rating Agencies that


 



    -13-


     


    

 


were engaged by the Depositor to rate such Securitization)
and all references herein to the “Servicing Agreement” shall mean such subsequent Servicing Agreement; provided,
however, that until a replacement Servicing Agreement has been entered into (and such written confirmation has been obtained),
the Note A-1 Holder shall cause the Mortgage Loan to be serviced pursuant to the provisions of the Servicing Agreement as
if such agreement was still in full force and effect with respect to the Mortgage Loan; provided, further, however,
that until a replacement Servicing Agreement is in place, the actual servicing of the Mortgage Loan may be performed by any Qualified
Servicer appointed by the Note A-1 Holder and does not have to be performed by the service providers set forth under the Servicing
Agreement that was previously in effect.


 


(e)        Notwithstanding
anything to the contrary contained herein (including Sections 4 and 13(a)), each Servicing Agreement shall provide
that the Servicer shall be required to service and administer the Mortgage Loan in accordance with the Servicing Standard as set
forth in such Servicing Agreement, and any Holder who is not the Borrower or an Affiliate of the Borrower shall be deemed a third-party
beneficiary of such provisions of the Servicing Agreement that run to the benefit of such Holder. It is understood that the Non-Lead
Note Holder may separately appoint a servicer for the Non-Lead Note, by itself or together with other assets, but any such servicer
will have no responsibility hereunder and shall be compensated solely by the Non-Lead Note Holder from funds payable to it hereunder
or otherwise.


 


(f)        The
Holders acknowledge that the Servicer is to comply with this Agreement and the Mortgage Loan Documents in connection with the servicing
of the Mortgage Loan.


 


(g)       If
any Note is included as an asset of a real estate mortgage investment conduit (a “REMIC”), within the meaning
of Section 860D(a) of the Code, then, any provision of this Agreement to the contrary notwithstanding: (i) the Mortgage
Loan shall be administered such that the Notes shall qualify at all times as (or as interests in) a “qualified mortgage”
within the meaning of Section 860G(a)(3) of the Code, (ii) any real property (and related personal property) acquired
by or on behalf of the Holders pursuant to a foreclosure, exercise of a power of sale or delivery of a deed in lieu of foreclosure
of the Mortgage or lien on such property following a default on the Mortgage Loan shall be administered so that the interest of
the pro rata share of each Holder therein shall at all times qualify as “foreclosure property” within the meaning
of Section 860G(a)(8) of the Code, and (iii) no Servicer may modify, waive or amend any provision of the Mortgage Loan,
consent to or withhold consent from any action of the Borrower, or exercise or refrain from exercising any powers or rights that
the Holders may have under the Mortgage Loan Documents, if any such action would constitute a “significant modification”
of the Mortgage Loan, within the meaning of Section 1.860G-2(b) of the regulations of the United States Department of
the Treasury, more than three (3) months after the startup day of the REMIC that includes any Note (or any portion thereof). Each
Holder agrees that the provisions of this paragraph shall be effected by compliance with any REMIC provisions in the Servicing
Agreement relating to the administration of the Mortgage Loan.


 


(h)       In
the event that one of the Notes is included in a REMIC, the other Holder shall not be required to reimburse such Holder or any
other Person for payment of any taxes imposed on such REMIC or Advances therefor or for any interest on such Advance or for


 



    -14-


     


    

 


deficits
in other items of disbursement or income resulting from the use of funds for payment of any such taxes, nor shall any disbursement
or payment otherwise distributable to the other Holder be reduced to offset or make-up any such payment or deficit.


 


3.         Priority
of Notes. Note A-1 and Note A-2 shall be of equal priority, and no portion of any of Note A-1 or
Note A-2 shall have priority or preference over any portion of the other Note or security therefor. Except for the
Excluded Amounts, all amounts tendered by the Borrower or otherwise available for payment on the Mortgage Loan, whether
received in the form of Monthly Payments, a balloon payment, Liquidation Proceeds, proceeds under any guaranty, letter of
credit or other instrument serving as security on the Mortgage Loan, proceeds under title, hazard or other insurance policies
or awards or settlements in respect of condemnation proceedings or similar exercise of the power of eminent domain shall be
distributed by the Master Servicer and applied to Note A-1 and Note A-2 on a Pro Rata and Pari Passu Basis.


 


The Servicing Agreement
may provide for the application of Penalty Charges paid in respect of the Mortgage Loan to be used to (i) pay the Master Servicer,
the Trustee or the Special Servicer for interest accrued on any Property Advances, (ii) to pay the parties to any Securitization
for interest accrued on any P&I Advance, (iii) to pay certain other expenses incurred with respect to the Mortgage Loan
and (iv) to pay to the Master Servicer and/or the Special Servicer as additional servicing compensation, except that, for
so long as Note A-1 is not included in a Securitization, any Penalty Charges allocated to Note A-1 that are not applied
pursuant to clauses (i)-(iii) above shall be remitted to the respective Holder and shall not be paid to the Master Servicer and/or
the Special Servicer without the express consent of such Holder.


 


4.         Workout.
Notwithstanding anything to the contrary contained herein, but subject to the terms and conditions of the Servicing Agreement
and Section 13 of this Agreement, and the obligation to act in accordance with the Servicing Standard, if the
Lead Note Holder, or any Servicer, in connection with a workout or proposed workout of the Mortgage Loan, modifies the terms
thereof such that (i) the Mortgage Loan Principal Balance is decreased, (ii) the Mortgage Interest Rate is reduced,
(iii) payments of interest or principal on Note A-1 or Note A-2 are waived, reduced or deferred or
(iv) any other adjustment is made to any of the payment terms of the Mortgage Loan, such modification shall not alter,
and any modification of the Mortgage Loan Documents shall be structured to preserve, the equal priorities of Note A-1
and Note A-2 as described in Section 3.


 


5.         Accounts;
Payment Procedure. The Servicing Agreement shall provide that the Master Servicer shall establish and maintain the
Collection Account or Collection Accounts, as applicable. Each of the Note A-1 Holder and the Note A-2 Holder
hereby directs the Master Servicer, in accordance with the priorities set forth in Section 3 hereof, and subject
to the terms of the Servicing Agreement, (i) to deposit into the applicable Collection Account within the time period
specified in the Servicing Agreement all payments received with respect to the Mortgage Loan and (ii) to remit from the
applicable Collection Account for deposit or credit on the applicable Master Servicer Remittance Date all payments received
with respect to and allocable to Note A-1 and Note A-2, by wire transfer to accounts maintained by the
Note A-1 Holder and the Note A-2 Holder, respectively; provided that delinquent payments


 



    -15-


     


    

 


received by the Master
Servicer after the related Master Servicer Remittance Date shall be remitted by the Master Servicer to such accounts within
the time period specified in the Servicing Agreement.


 


If any Servicer holding
or having distributed any amount received or collected in respect of Note A-1 or Note A-2 determines, or a court of competent
jurisdiction orders, at any time that any amount received or collected in respect of Note A-1 or Note A-2 must, pursuant
to any insolvency, bankruptcy, fraudulent conveyance, preference or similar law, be returned to the Borrower or paid to the Note A-1
Holder, the Note A-2 Holder, or any Servicer or paid to any other Person, then, notwithstanding any other provision of this
Agreement, no Servicer shall be required to distribute any portion thereof to the Note A-1 Holder or the Note A-2 Holder, as applicable,
and such Note A-1 Holder or Note A-2 Holder, as applicable, shall promptly on demand repay to such Servicer the portion that has
been distributed to the Note A-1 Holder or the Note A-2 Holder, as applicable, together with interest thereon at such rate, if
any, as such Servicer shall have been required to pay to the Borrower, the Note A-1 Holder, the Note A-2 Holder, any
Servicer or such other person or entity with respect thereto. Each of the Note A-1 Holder and the Note A-2 Holder agrees
that if at any time it shall receive from any sources whatsoever any payment on account of the Mortgage Loan in excess of its distributable
share thereof, it will promptly remit such excess to the Master Servicer. The Master Servicer shall have the right to offset any
amounts due hereunder from the Note A-1 Holder or the Note A-2 Holder, as applicable, with respect to the Mortgage Loan
against any future payments due to the Note A-1 Holder or the Note A-2 Holder, as applicable, under the Mortgage Loan,
provided, that the obligations of the Note A-1 Holder and the Note A-2 Holder under this Section 5
are separate and distinct obligations from one another and in no event shall any Servicer enforce the obligations of any Holder
against any other Holder. The obligations of the Note A-1 Holder and the Note A-2 Holder under this Section 5
constitute absolute, unconditional and continuing obligations and each Servicer shall be deemed a third-party beneficiary of these
provisions.


 


6.         Limitation
on Liability. Subject to the terms of the Servicing Agreement, no Holder (including the Master Servicer or the Special
Servicer on its behalf) shall have any liability to any other Holder with respect to any Note, except (1) with respect
to the Advance reimbursement provisions set forth in Section 17 and (2) with respect to losses actually
suffered due to the gross negligence, willful misconduct or material breach of this Agreement on the part of such Holder
(including the Master Servicer or the Special Servicer on its behalf, except that the Master Servicer’s or Special
Servicer’s liability is further limited or expanded as set forth in the Servicing Agreement).


 


7.         Representations
of the Holders. (a)  Each of the initial Holders hereby represents and warrants to, and covenants with each
other Holder that, as of the date hereof:


 


(i)         It
is duly organized, validly existing and in good standing under the laws of the State under which it is organized.


 


(ii)        The
execution and delivery of this Agreement by such Holder, and performance of, and compliance with, the terms of this Agreement by
such Holder, will not violate its organizational documents or constitute a default (or an event which, with


 



    -16-


     


    

 


notice or lapse of
time, or both, would constitute a default) under, or result in the breach of, any material agreement or other instrument to which
it is a party or that is applicable to it or any of its assets, in each case which materially and adversely affect its ability
to carry out the transactions contemplated by this Agreement.


 


(iii)       Such
Holder has the full power and authority to enter into and consummate all transactions contemplated by this Agreement, has duly
authorized the execution, delivery and performance of this Agreement and has duly executed and delivered this Agreement.


 


(iv)      This
Agreement is the legal, valid and binding obligation of such Holder enforceable against such Holder in accordance with its terms,
except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium 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), and except that the enforcement of rights with respect to indemnification and
contribution obligations may be limited by applicable law.


 


(v)       It
has the right to enter into this Agreement without the consent of any third party.


 


(vi)      It
is the holder of the respective Note for its own account in the ordinary course of its business.


 


(vii)     It
has not dealt with any broker, investment banker, agent or other person, that may be entitled to any commission or compensation
in connection with the consummation of any of the transactions contemplated hereby.


 


(viii)    It
is a Qualified Transferee.


 


8.         Independent
Analyses of each Holder. Each Holder acknowledges that, except for the representations made in Section 7, it
has, independently and without reliance upon any other Holder and based on such documents and information as such Holder has
deemed appropriate, made its own credit analysis and decision to purchase its respective Note. Each Holder hereby
acknowledges that the other Holder shall have no responsibility for (i) the collectability of the Mortgage Loan,
(ii) the validity, enforceability or legal effect of any of the Mortgage Loan Documents or the title insurance policy or
policies or any survey furnished or to be furnished in connection with the origination of the Mortgage Loan, (iii) the
validity, sufficiency or effectiveness of the lien created or to be created by the Mortgage Loan Documents, or (iv) the
financial condition of the Borrower. Each Holder assumes all risk of loss in connection with its respective Note for reasons
other than gross negligence, willful misconduct or breach of this Agreement by any other Holder or negligence, willful
misconduct or bad faith by any Servicer.


 


9.       No
Creation of a Partnership or Exclusive Purchase Right. Nothing contained in this Agreement, and no action taken pursuant
hereto, shall be deemed to constitute among any Holder (or the Master Servicer, Special Servicer or Trustee on its behalf)
and any


 



    -17-


     


    

 


other Holder a partnership, association, joint venture or other entity. Each Holder (or the Master Servicer, Special
Servicer or Trustee on its behalf) shall have no obligation whatsoever to offer to the other Holder the opportunity to
purchase notes or interests relating to any future loans originated by such Holder or any of its Affiliates, and if any
Holder chooses to offer to the other Holder, the opportunity to purchase notes or interests in any future mortgage loans
originated by such Holder or its Affiliates, such offer shall be at such purchase price and interest rate as such Holder
chooses, in its sole and absolute discretion. Neither Holder shall have any obligation whatsoever to purchase from the other
Holder any notes or interests in any future loans originated by the other Holder or any of its Affiliates.


 


10.       Not
a Security. Neither of Note A-1 nor Note A-2 shall be deemed to be a security within the meaning of the
Securities Act of 1933 or the Securities Exchange Act of 1934.


 


11.       Other
Business Activities of the Holders. Each Holder acknowledges that the other Holder may make loans or otherwise extend
credit to, and generally engage in any kind of business with, any Affiliate of the Borrower, and receive payments on such
other loans or extensions of credit to any Affiliate of the Borrower and otherwise act with respect thereto freely and
without accountability, but only if none of the foregoing violate the Mortgage Loan Documents, in the same manner as if this
Agreement and the transactions contemplated hereby were not in effect.


 


12.       Transfer
of Notes. (a)  Each Holder may Transfer up to 49% (in the aggregate) of its beneficial interest in its Note
whether or not the related transferee is a Qualified Transferee without a Rating Agency Confirmation. Each Holder shall not
Transfer more than 49% (in the aggregate) of its beneficial interest in its Note unless (i) prior to a Securitization of
any Note, the other Holder has consented to such Transfer, in which case the related transferee shall thereafter be deemed to
be a “Qualified Transferee” for all purposes under this Agreement, (ii) after a Securitization of any Note,
a Rating Agency Confirmation has been received with respect to such Transfer, in which case the related transferee shall
thereafter be deemed to be a “Qualified Transferee” for all purposes under this Agreement, (iii) such
Transfer is to a Qualified Transferee, or (iv) such Transfer is in connection with a sale by Securitization trust. Any such
transferee must assume in writing the obligations of the transferring Holder hereunder and agree to be bound by the terms and
provisions of this Agreement and the Servicing Agreement. Such proposed transferee (except in the case of Transfers that are
made in connection with a Securitization) shall also remake each of the representations and warranties contained herein for
the benefit of the other Holder. Notwithstanding the foregoing, without the non-transferring Holder’s prior consent
(which will not be unreasonably withheld), and, if such non-transferring Holder’s Note is in a Securitization, without
a Rating Agency Confirmation from each Rating Agency that has been engaged by the Depositor to rate the securities issued in
connection with such Securitization, no Holder shall Transfer all or any portion of its Note to the Borrower or an Affiliate
of the Borrower and any such Transfer shall be absolutely null and void and shall vest no rights in the
purported transferee.


 


(b)       Except
for a Transfer made in connection with a Securitization, or a Transfer made by an initial Holder to an Affiliate, at least five
(5) days prior to a transfer of any


 



    -18-


     


    

 


Note, the transferring Holder shall provide to the other Holder and, if any Certificates are
outstanding, to the Rating Agencies, a certification that such transfer will be made in accordance with this Section 12,
such certification to include (1) the name and contact information of the transferee and (2) if applicable, a certification
by the transferee that it is a Qualified Transferee.


 


(c)        The
Holders acknowledge that any Rating Agency Confirmation may be granted or denied by the Rating Agencies in their sole and absolute
discretion and that such Rating Agencies may charge the transferring Holder customary fees in connection with providing such Rating
Agency Confirmation.


 


(d)       Notwithstanding
anything to the contrary contained herein, each Holder may pledge or transfer (a “Pledge”) its Note to any entity
(other than the Borrower or any Affiliate of the Borrower) that has extended a credit facility to such Holder or has entered into
a repurchase agreement with such Holder and that, in each case, is either a Qualified Transferee or a financial institution whose
long-term unsecured debt is rated at least “A” (or the equivalent) or better by each Rating Agency (a “Note
Pledgee”), or to a Person with respect to which a Rating Agency Confirmation has been obtained, on terms and conditions
set forth in this Section 12(d), it being further agreed that a financing provided by a Note Pledgee to any Holder
or any Affiliate that controls such Holder that is secured by such Holder’s interest in its respective Note and is structured
as a repurchase arrangement, shall qualify as a “Pledge” hereunder on the condition that all applicable terms and conditions
of this Section 12 are complied with. A Note Pledgee that is not a Qualified Transferee may not take title to a Note
without a Rating Agency Confirmation. Upon written notice, if any, by the pledging Holder to the other Holder and the Servicer
that a Pledge has been effected (including the name and address of the applicable Note Pledgee), the other Holder agrees to acknowledge
receipt of such notice and thereafter agree: (i) to give such Note Pledgee written notice of any default by the pledging Holder
in respect of its obligations under this Agreement of which default such Holder has actual knowledge and which notice shall be
given simultaneously with the giving of such notice to the pledging Holder; (ii) to allow such Note Pledgee a period of ten
(10) Business Days to cure a default by the pledging Holder in respect of its obligations to the other Holder hereunder, but such
Note Pledgee shall not be obligated to cure any such default; (iii) that no amendment, modification, waiver or termination
of this Agreement or the Servicing Agreement (if the pledging Holder had the right to consent to such amendment, modification,
waiver or termination pursuant to the terms hereof) shall be effective against such Note Pledgee without the written consent of
such Note Pledgee, which consent shall not be unreasonably withheld, conditioned or delayed and which consent shall be deemed to
be given if Note Pledgee shall fail to respond to any request for consent to any such amendment, modification, waiver or termination
within 10 days after request therefor; (iv) that the other Holder shall accept any cure by such Note Pledgee of any default
of the pledging Holder which such pledging Holder has the right to effect hereunder, as if such cure were made by such pledging
Holder; (v) that the other Holder or Servicer shall deliver to Note Pledgee such estoppel certificate(s) as Note Pledgee shall
reasonably request, provided that any such certificate(s) shall be in a form reasonably satisfactory to the other Holder;
and (vi) that, upon written notice (a “Redirection Notice”) to the Servicer by such Note Pledgee that the
pledging Holder is in default beyond any applicable cure periods with respect to the pledging Holder’s obligations to such
Note Pledgee pursuant to the applicable credit agreement or other agreements relating to the Pledge between the pledging Holder
and such Note Pledgee (which notice need not be joined in or confirmed by the pledging Holder), and until such Redirection


 



    -19-


     


    

 


Notice
is withdrawn or rescinded by such Note Pledgee, Note Pledgee (or at any time that pledging Holder otherwise directs that such payment
be made to Note Pledgee pursuant to a separate notice) shall be entitled to receive any payments that any Servicer would otherwise
be obligated to make to the pledging Holder from time to time pursuant to this Agreement or any Servicing Agreement. Any pledging
Holder hereby unconditionally and absolutely releases the other Holder and any Servicer from any liability to the pledging Holder
on account of any Holder’s or Servicer’s compliance with any Redirection Notice believed by any Servicer or other Holder
in good faith to have been delivered by a Note Pledgee. Note Pledgee shall be permitted to exercise fully its rights and remedies
against the pledging Holder (and accept an assignment in lieu of foreclosure as to such collateral), in accordance with applicable
law, the pledge agreement, repurchase agreement or similar agreement between the pledging Holder and the Note Pledgee and this
Agreement. In such event, or if the pledging holder otherwise assigns its interests to the Note Pledgee, the other Holder and the
Servicer shall recognize such Note Pledgee (and any transferee (other than the Borrower or any Affiliate of the Borrower) that
is also a Qualified Transferee at any foreclosure or similar sale held by such Note Pledgee or any transfer in lieu of foreclosure),
and such Person’s successor and assigns, as the successor to the pledging Holder’s rights, remedies and obligations
under this Agreement, and any such Note Pledgee or Qualified Transferee shall assume in writing the obligations of the pledging
Holder hereunder accruing from and after such Transfer (i.e., realization upon the collateral by such Note Pledgee) and
agrees to be bound by the terms and provisions of this Agreement. The rights of a Note Pledgee under this Section 12(d) shall
remain effective as to any Holder (and any Servicer) unless and until such Note Pledgee shall have notified such Holder (and any
Servicer, as applicable) in writing that its interest in the pledged Note has terminated.


 


13.       Exercise
of Remedies by the Servicer. (a)  Subject to the terms of this Agreement and the Servicing Agreement and
subject to the rights and consents, where required, of the Directing Holder, the Servicer shall have the sole and exclusive
authority with respect to the administration of, and exercise of rights and remedies with respect to, the Mortgage Loan,
including, without limitation, the sole and exclusive authority to (i) modify or waive any of the terms of the Mortgage
Loan Documents, (ii) consent to any action or failure to act by the Borrower or any party to the Mortgage Loan
Documents, (iii) vote all claims with respect to the Mortgage Loan in any bankruptcy, insolvency or other similar
proceedings and (iv) to take legal action to enforce or protect the Holders’ interests with respect to the
Mortgage Loan or to refrain from exercising any powers or rights under the Mortgage Loan Documents, including the right at
any time to call or waive any Events of Default, or accelerate or refrain from accelerating the Mortgage Loan or institute
any foreclosure action, and the Holders shall have no voting, consent or other rights whatsoever with respect to the
Servicer’s administration of, or exercise of its rights and remedies with respect to, the Mortgage Loan other than as
provided in the Servicing Agreement. Subject to the terms and conditions of the Servicing Agreement, the Servicer shall have
the sole and exclusive authority to make Property Advances with respect to the Mortgage Loan. Except as otherwise provided in
this Agreement, each Holder agrees that it shall have no right to, and hereby presently and irrevocably assigns and conveys
to the Servicer the rights, if any, that such Holder has to (A) call or cause the Servicer to call an Event of Default
under the Mortgage Loan, or (B) exercise any remedies with respect to the Mortgage Loan or the Borrower, including,
without limitation, filing or causing the Lead Note Holder or such Servicer to file any bankruptcy petition against the
Borrower. Each Holder shall, from time to time,


 



    -20-


     


    

 


execute such documents as any Servicer shall reasonably require to
evidence such assignment with respect to the rights described in clause (iii) of the first sentence in this Section 13(a).


 


(b)       The
Lead Servicer and the related Trustee shall not have any fiduciary duty to the Non-Lead Note Holder in connection with the administration
of the Mortgage Loan (but the foregoing shall not relieve the Lead Servicer and the related Trustee from their respective obligation
under the Servicing Agreement to make any disbursement of funds as set forth herein).


 


(c)        The
Holders hereby acknowledge that the Servicing Agreement shall provide that, subject to the satisfaction of the conditions set forth
in the next sentence, upon the Mortgage Loan becoming a Defaulted Mortgage Loan, if the Special Servicer determines to sell the
Defaulted Mortgage Loan (or the Lead Note), it will be required to sell the entire Defaulted Mortgage Loan as a single whole loan
(i.e., both the Lead Note and Non-Lead Note). Any such sale of the entire Defaulted Mortgage Loan is subject to the satisfaction
of the following:


 


(i)         The
Non-Lead Note Holder has provided written consent to such sale; or


 


(ii)        The
Special Servicer has delivered the following notices and information to the Non-Lead Note Holder:


 


(1)       at
least 15 Business Days prior written notice of any decision to attempt to sell the Defaulted Mortgage Loan;


 


(2)       at
least 10 days prior to the proposed sale date, a copy of each bid package (together with any amendments to such bid packages)
received by the Special Servicer in connection with any such proposed sale;


 


(3)       at
least 10 days prior to the proposed sale date, a copy of the most recent Appraisal for the Mortgage Loan, and any documents
in the Servicing File reasonably requested by a Non-Lead Note Holder; and


 


(4)       until
the sale is completed and a reasonable period of time (but no less time than is afforded to other offerors and the Directing Holder)
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 Non-Lead Note Holder
may waive any delivery or timing requirements set forth above only for itself. Subject to the foregoing, each of the Lead Note
Holder, the Directing Holder, the Non-Lead Note Holder and the Non-Directing Holder shall be permitted to submit an offer at any
sale of the Defaulted Mortgage Loan (unless such Person is the Borrower or an agent or Affiliate of the Borrower).


 


The Non-Lead Note Holder
hereby appoints the Lead Note Holder as their agent, and grant to the Lead Note Holder an irrevocable power of attorney coupled
with an interest, and


 



    -21-


     


    

 


its proxy, for the purpose of soliciting and accepting offers for and consummating the sale of the Non-Lead
Note. The Non-Lead Note Holder further agrees that, upon the request of the Lead Note Holder, the Non-Lead Note Holder shall execute
and deliver to or at the direction of Lead Note Holder such powers of attorney or other instruments as the Lead Note Holder may
reasonably request to better assure and evidence the foregoing appointment and grant, in each case promptly following such request,
and shall deliver the related original Non-Lead Note, endorsed in blank, to or at the direction of the Lead Note Holder in connection
with the consummation of any such sale.


 


The authority of the
Lead Note Holder to sell the Non-Lead Note, and the obligations of the Non-Lead Note Holder to execute and deliver instruments
or deliver the Non-Lead Note upon request of the Lead Note Holder, shall terminate and cease to be of any further force or effect
upon the date, if any, upon which the Lead Note is repurchased by Natixis, as the initial Note A-1 Holder from the trust fund
established under the Servicing Agreement in connection with a material breach of representation or warranty made by the initial
Note A-1 Holder with respect to the Lead Note or material document defect with respect to the documents delivered by Natixis,
as the initial Note A-1 Holder with respect to the Lead Note upon the consummation of the Lead Securitization.


 


(d)       Notwithstanding
anything to the contrary contained herein, the exercise by the Servicer on behalf of the Holders of its rights under this Section 13
shall be subject in all respects to any section of the Servicing Agreement governing REMIC administration, and in no event shall
the Servicer be permitted to take any action or refrain from taking any action if taking or failing to take such action, as the
case may be, would violate the laws of any applicable jurisdiction, breach the Mortgage Loan Documents or be inconsistent with
the Servicing Standard or violate any other provisions of the Servicing Agreement or violate the REMIC provisions of the Code or
any regulations promulgated thereunder, including, without limitation, the provisions of Section 2(g) of this Agreement.


 


14.       Rights
of the Directing Holder. The Directing Holder shall be entitled to exercise the rights and powers granted to the
Directing Holder hereunder and the rights and powers granted to the “Directing Holder,” “Controlling
Class Certificateholder,” “Controlling Class Representative” or similar party under, and as defined
in, the Servicing Agreement with respect to the Mortgage Loan. In addition, the Directing Holder shall be entitled to advise
(1) the Special Servicer with respect to all matters related to a Specially Serviced Mortgage Loan and (2) the
Special Servicer with respect to all matters for which the Master Servicer must obtain the consent or deemed consent of the
Special Servicer, and, except as set forth below (i) the Master Servicer shall not be permitted to take any Major Action
unless it has obtained the prior written consent of the Special Servicer and (ii) the Special Servicer shall not be
permitted to consent to the Master Servicer’s taking any Major Action nor will the Special Servicer itself be permitted
to take any Major Action as to which the Directing Holder has objected in writing within ten (10) Business Days (or
30 days with respect to an Acceptable Insurance Default) after receipt of the written recommendation and analysis and
such additional information requested by the Directing Holder as may be necessary in the reasonable judgment of the Directing
Holder in order to make a judgment with respect to such Major Action. The Directing Holder may also direct the Special


 



    -22-


     


    

 


Servicer to take, or to refrain from taking, such other actions with respect to the Mortgage Loan as the Directing Holder may
deem advisable, subject to the terms of the Servicing Agreement.


 


If the Directing Holder
fails to notify the Special Servicer of its approval or disapproval of any proposed Major Action within ten (10) Business Days
(or 30 days with respect to an Acceptable Insurance Default) after delivery to the Directing Holder by the applicable Servicer
of written notice of a proposed Major Action together with any information requested by the Directing Holder as may be necessary
in the reasonable judgment of the Directing Holder in order to make a judgment, then upon the expiration of such ten (10) Business
Day (or 30 days with respect to an Acceptable Insurance Default) period, such Major Action shall be deemed to have been approved
by the Directing Holder.


 


In the event that the
Special Servicer or Master Servicer (in the event the Master Servicer is otherwise authorized by the Servicing Agreement to take
such action), as applicable, determines that immediate action, with respect to the foregoing matters, or any other matter requiring
consent of the Directing Holder is necessary to protect the interests of the Holders (as a collective whole) and the Special Servicer
has made a reasonable effort to contact the Directing Holder, the Master Servicer or the Special Servicer, as the case may be,
may take any such action without waiting for the Directing Holder’s response.


 


No objection, direction
or advice contemplated by the preceding paragraphs may require or cause the Master Servicer or the Special Servicer, as applicable,
to violate any provision of the Mortgage Loan Documents, applicable law, the Servicing Agreement, this Agreement, the REMIC provisions
of the Code or the Master Servicer or Special Servicer’s obligation to act in accordance with the Servicing Standard or expose
the Master Servicer or the Special Servicer to liability, or materially expand the scope of the Master Servicer’s or Special
Servicer’s responsibilities under the Servicing Agreement.


 


The Directing Holder
shall have no liability to the other Holder or any other Person for any action taken, or for refraining from the taking of any
action or the giving of any consent or the failure to give any consent pursuant to this Agreement or the Servicing Agreement, or
errors in judgment, absent any loss, liability or expense incurred by reason of its willful misfeasance, bad faith or gross negligence.
The Holders agree that the Directing Holder may take or refrain from taking actions, or give or refrain from giving consents, that
favor the interests of one Holder over the other Holder, and that the Directing Holder may have special relationships and interests
that conflict with the interests of another Holder and, absent willful misfeasance, bad faith or gross negligence on the part of
the Directing Holder agree to take no action against the Directing Holder or any of its officers, directors, employees, principals
or agents as a result of such special relationships or interests, and that the Directing Holder will not be deemed to have been
grossly negligent or reckless, or to have acted in bad faith or engaged in willful misfeasance or to have recklessly disregarded
any exercise of its rights by reason of its having acted or refrained from acting, or having given any consent or having failed
to give any consent, solely in the interests of any Holder.


 


The Holders acknowledge
that the Servicing Agreement may contain certain provisions that give an operating advisor certain non-binding consultation rights
with respect to Major Actions.


 



    -23-


     


    

 


15.       Appointment
of Special Servicer. Subject to the terms of the Servicing Agreement, the Directing Holder shall have the right at any
time and from time to time, with or without cause, to replace the Special Servicer then acting with respect to the Mortgage
Loan and appoint a Qualified Servicer as the replacement Special Servicer in lieu thereof. The Directing Holder shall
designate a Person to serve as Special Servicer by delivering to the other Holder and the parties to the Note A-1 PSA
and the UBS 2017-C5 PSA a written notice stating such designation and by satisfying the other conditions required under the
Servicing Agreement (including, without limitation, a Rating Agency Confirmation, if required by the terms of the Servicing
Agreement), if any.


 


The Directing Holder
agrees and acknowledges that prior to the Note A-1 Securitization, the Special Servicer could be terminated under the UBS 2017-C5
PSA in connection with a “servicer termination event” thereunder, or otherwise based on a recommendation by the operating
advisor under the UBS 2017-C5 PSA if (1) the operating advisor determines, in its sole discretion exercised in good faith, that
(a) the Special Servicer has failed to comply with the Servicing Standard and (b) a replacement of the Special Servicer would be
in the best interest of the holders of Certificates issued under UBS 2017-C5 PSA (as a collective whole) and (2) the affirmative
vote of the requisite certificate holders is obtained. The Directing Holder will retain its right to remove and replace the Special
Servicer, but the Directing Holder may not restore a Special Servicer that has been removed in accordance with the preceding sentence.


 


16.       Rights
of the Non-Directing Holder. (a)  The Servicing Agreement shall provide that the Servicer shall be
required:


 


(i)         to
provide copies of the same notices, information and reports that it is required to provide to the Directing Holder pursuant to
the Servicing Agreement with respect to any Major Actions or the implementation of any recommended actions outlined in an Asset
Status Report relating to the Mortgage Loan to the Non-Directing Holder (but without regard to whether or not the Directing Holder
actually has lost any rights to receive such information as a result of a Consultation Termination Event), within the same time
frame as specified with respect to the Directing Holder (but without regard to whether or not the Directing Holder actually has
lost any rights to receive such information as a result of a Consultation Termination Event); provided, however,
that if Note A-2 has been included in a Securitization, then for any information for which the Special Servicer would be required
to provide to such Non-Directing Holder, the Special Servicer shall provide such notice to the master servicer of the other Securitization
transaction, who shall forward such notice as and when required under the terms of the related Securitization documents; and


 


(ii)        to
consult with the Non-Directing Holder on a strictly non-binding basis, if, having received such notices, information and reports,
such Non-Directing Holder requests consultation with respect to any such Major Action or the implementation of any recommended
actions outlined in an Asset Status Report relating to the Mortgage Loan, and consider alternative actions recommended by the Non-Directing
Holder; provided that after the expiration of a period of ten (10) Business Days from the delivery to the Non-Directing
Holder of written notice of a proposed action, together with copies of the


 



    -24-


     


    

 


notice, information and report required to be provided
to the Directing Holder, the Servicer shall no longer be obligated to consult with the Non-Directing Holder, whether or not the
Non-Directing Holder has responded within such ten (10) Business Day period (unless the Servicer proposes a new course of action
that is materially different from the action previously proposed, in which case such ten (10) Business Day period shall be begin
anew from the date of such proposal and delivery of all information relating thereto).


 


(b)       Notwithstanding
the foregoing non-binding consultation rights of the Non-Directing Holder, the Servicer may take any Major Action or any action
set forth in the Asset Status Report before the expiration of the aforementioned ten (10) Business Day period if the Servicer determines
that immediate action with respect thereto is necessary to protect the interests of the Holders.


 


(c)        In
addition to the foregoing non-binding consultation rights, the Non-Directing Holder shall have the right to annual conference calls
with the Master Servicer or the Special Servicer, 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 Mortgage Loan are discussed.


 


(d)       In
no event shall the Servicer be obligated at any time to follow or take any alternative actions recommended by the Non-Directing
Holder.


 


(e)       Any
Non-Directing Holder that is the Borrower or an Affiliate of the Borrower shall not be entitled to any of the rights set forth
in this Section 16.


 


17.       Advances;
Reimbursement of Advances. (a)  From time to time, (i) pursuant to terms of the Servicing Agreement, the
Lead Servicer and/or the related Trustee may be obligated to make (1) Property Advances with respect to the Mortgage
Loan or the Mortgaged Property and (2) P&I Advances with respect to the Lead Note and (ii) pursuant to the
terms of the Non-Lead Servicing Agreement, the related Non-Lead Master Servicer and/or the related Trustee may be obligated
to make P&I Advances with respect to the Non-Lead Note. The Lead Servicer and/or the related Trustee will not be required
to make any P&I Advance with respect to the Non-Lead Note and the related Non-Lead Master Servicer and/or the related
Trustee will not be required to make any P&I Advance with respect to any Lead Note or any Property Advance. The Lead
Servicer, the Non-Lead Master Servicer and any Trustee will be entitled to interest on any Advance made in the manner and
from the sources provided in the Note A-1 PSA and the UBS 2017-C5 PSA, as applicable.


 


(b)       The
Lead Servicer and the related Trustee, as applicable, will be entitled to reimbursement for a Property Advance, first from
the Collection Account established with respect to the Mortgage Loan, and then, if such Property Advance is a Nonrecoverable
Advance, if such funds on deposit in the Collection Account are insufficient, from general collections of the Lead Securitization
as provided in the Servicing Agreement.


 


(c)       To
the extent amounts on deposit in the Collection Account with respect to the Mortgage Loan are insufficient to reimburse the Lead
Servicer for any Property Advance


 



    -25-


     


    

 


and/or interest thereon and the Lead Servicer or the related Trustee, as applicable, obtains
funds from general collections of the Lead Securitization as a reimbursement for a Property Advance or interest thereon, the Non-Lead
Note Holder (including any Securitization into which the Non-Lead Note is deposited) shall be required to, promptly following notice
from the Lead Servicer, pay to the Lead Securitization for its pro rata share of such Property Advance and/or interest thereon
at the Reimbursement Rate. In addition, the Non-Lead Note Holder (including any Securitization into which the Non-Lead Note is
deposited) shall promptly reimburse the Lead Servicer or the related Trustee for the Non-Lead Note Holder’s pro rata
share of any fees, costs or expenses incurred in connection with the servicing and administration of the Mortgage Loan as to which
the Lead Securitization or any of the parties thereto are entitled to be reimbursed pursuant to the terms of the Servicing Agreement
(to the extent amounts on deposit in the Collection Account with respect to the Mortgage Loan are insufficient for reimbursement
of such amounts).


 


(d)       The
parties to each of the Note A-1 PSA and the UBS 2017-C5 PSA shall each be entitled to make their own recoverability determination
with respect to a P&I Advance based on the information that they have on hand and in accordance with the Note A-1 PSA
and the UBS 2017-C5 PSA, as applicable.


 


(e)        If
the Lead Servicer or the related Trustee elects to defer the reimbursement of a Property Advance in accordance with the terms of
the Servicing Agreement, the Lead Servicer or the related Trustee shall also defer its reimbursement of the Non-Lead Note share
from the Non-Lead Note Holder.


 


18.       Provisions
Relating to Securitization.


 


(a)       New
Notes. For so long as Natixis or an Affiliate of Natixis (an “Initial Note A-1 Holder”) is the owner of
Note A-1, such Initial Note A-1 Holder shall have the right, subject to the terms of the Mortgage Loan Documents, to cause the
Borrower to execute amended and restated notes or additional notes (in either case, the “New A-1 Notes”) reallocating
the principal of Note A-1 among other New A-1 Notes; reducing the Interest Rates of such New A-1 Notes or severing the Note A-1
into one or more further “component” notes in the aggregate principal amount equal to the then outstanding principal
balance of Note A-1, provided that (i) the aggregate principal balance of the Amended A-1 Notes and New A-1 Notes following
such amendments is no greater than the principal balance of Note A-1 prior to such amendments, (ii) all New A-1 Notes continue
to have the same interest rate as the Note A-1 prior to such amendments, (iii) all New A-1 Notes pay pro rata and on a pari
passu basis and such reallocated or component notes shall be automatically subject to the terms of this Agreement and (iv)
the Initial Note A-1 Holder holding the New A-1 Notes shall notify the parties to the UBS 2017-C5 PSA in writing of such modified
allocations and principal amounts. In connection with the foregoing, (1) the Master Servicer is hereby authorized to execute amendments
to the Loan Agreement and this Agreement (or to amend and restate the Loan Agreement and this Agreement) on behalf of either of
the Holders solely for the purpose of reflecting such reallocation of principal or such severing of Note A-1, (2) if a Note A-1
is severed into “component” notes, such component notes shall each have their same rights as the respective original
Note and (3) the definition of the term “Securitization” and all of the related defined terms may be amended (and new
terms added, as necessary) to reflect the New A-1


 



    -26-


     


    

 


Notes. Rating Agency Confirmation shall not be required for any amendments to
this Agreement required to facilitate the terms of this Section 18(a). The Initial Note A-1 Holder whose Note is being reallocated
or split pursuant to this Section 18(a) shall reimburse the other Holder for all costs and expenses incurred by the other
Holder in connection with the reallocation or split.


 


(b)       The
Non-Lead Note Holder agrees that (if the Non-Lead Note is included in a Securitization other than the Lead Securitization) it shall
cause the Non-Lead Servicing Agreement to provide as follows:


 


(i)         the
applicable master servicer and trustee for such Securitization shall be required to notify the master servicer, special servicer
and trustee of each other Securitization of the amount of any P&I Advance it has made with respect to the Note included in
such Securitization within two Business Days of making such advance;


 


(ii)        if
the applicable master servicer, special servicer or trustee determines that a proposed P&I Advance, if made, or any outstanding
P&I Advance previously made, would be, or is, as applicable, a nonrecoverable advance, the master servicer shall provide the
other servicers written notice of such determination within 2 Business Days after such determination was made;


 


(iii)       in
the event the Non-Lead Note Holder is responsible for its proportionate share of any Nonrecoverable Advances (or any other portion
of a Nonrecoverable Advance) (and advance interest thereon) or other fee or expense pursuant to Section 17, and funds received
with respect to the Non-Lead Note are insufficient to cover such amounts, (x) the related master servicer will be required
to pay the Master Servicer, Special Servicer or Lead Trustee, as applicable, out of general funds in the collection account (or
equivalent account) established under the Non-Lead Servicing Agreement and (y) if the Lead Servicing Agreement permits the
Master Servicer, Special Servicer or Lead Trustee to pay itself from the Lead Securitization Trust’s general account then
the master servicer under the Non-Lead Servicing Agreement will be required to reimburse the Lead Securitization Trust out of general
funds in the collection account (or equivalent account) established under the Non-Lead Servicing Agreement;


 


(iv)      each
of the Master Servicer and the Special Servicer shall be indemnified (as and to the extent the Lead Securitization Trust is required
to indemnify each such party) against any claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments
and any other costs, liabilities, fees and expenses, incurred in connection with any PSA that relate solely to its servicing of
the Mortgage Loan, as applicable, and the master servicer under the Non-Lead Servicing Agreement will be required to reimburse
the Master Servicer, Special Servicer or Lead Trustee, as applicable, out of general funds in the collection account (or equivalent
account) established under the Non-Lead Servicing Agreement;


 


(v)       each
of trustee and the master servicer under the Non-Lead Servicing Agreement, as applicable, shall acknowledge that, (i) each
of the Master Servicer and the Lead Trustee will be a third party beneficiary under the Non-Lead Servicing Agreement


 



    -27-


     


    

 


with respect
to any provisions therein relating to (1) the reimbursement of any nonrecoverable advances made with respect to such Non-Lead Note
by the Master Servicer or the Lead Trustee and (2) as to the Master Servicer only, the indemnification of the Master Servicer against
any claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments and any other costs, liabilities, fees
and expenses, incurred in connection with any PSA and relating to the Non-Lead Note and (ii) the Special Servicer will be
a third party beneficiary under the Non-Lead Servicing Agreement with respect to any provisions therein relating to (1) the reimbursement
of any nonrecoverable advances made with respect to the Non-Lead Note by the Special Servicer (it being understood that the Special
Servicer is not required to make any Advances) and (2) the indemnification of the Special Servicer against any claims, losses,
penalties, fines, forfeitures, legal fees and related costs, judgments and any other costs, liabilities, fees and expenses, incurred
in connection with any PSA and relating to such Non-Lead Note; and


 


(vi)      the
Master Servicer and the Special Servicer shall be third party beneficiaries of the foregoing provisions.


 


(c)        The
Note A-1 Holder shall provide the Depositor, the Servicer and the Special Servicer under the Note A-2 PSA (as of the Note A-1 Securitization
Date) (provided such party is not also a party to the Note A-1 PSA) notice of the Note A-1 Securitization in writing (which may
be by email) prior to or promptly following the Note A-1 Securitization Date. Such notice shall contain contact information for
each of the parties to the Note A-1 PSA and the identity of the Controlling Class Representative under such Note A-1 PSA. In addition,
after the Note A-1 Securitization Date, the Note A-1 Holder shall send a copy of the Note A-1 PSA to the Depositor, the Servicer
and the Special Servicer under the Note A-2 PSA (as of the Note A-1 Securitization Date) provided such party is not also a party
to the Note A-1 PSA.


 


(d)       The
Note A-1 PSA shall provide that:


 


(i)         the
Master Servicer and Trustee for such Securitization shall be required to notify the servicer, special servicer and trustee of each
other Securitization of the amount of any P&I Advance it has made with respect to the Note included in such Securitization
within two Business Days of making such advance;


 


(ii)        if
the Master Servicer or Trustee determines that a proposed P&I Advance, if made, or any outstanding P&I Advance previously
made, would be, or is, as applicable, a nonrecoverable advance, the Master Servicer shall provide the other servicers written notice
of such determination within 2 Business Days after such determination was made;


 


(iii)       the
Master Servicer shall remit all payments received (or advanced) with respect to the Non-Lead Note, net of its Servicing Fee and

(v)       the
Master Servicer, any primary servicer, the Special Servicer and the Lead Trustee, certificate administrator or other party acting
as custodian for the Lead Securitization shall be required to deliver (and shall be required to cause each other servicer and servicing
function participant (within the meaning of Items 1123 and 1122, respectively, of Regulation AB) retained or engaged by it to deliver),

    -29-


     


    

 


successor REO Property with respect thereto (exclusive of any
portion of such amount payable or reimbursable to any third party in accordance with this Agreement), unless such amount would
otherwise be included in the monthly remittance to the Holder of such Non-Lead Note for such month; provided, however,
that to the extent any such amounts are received after 3:00 p.m. Eastern time on any given Business Day, the Master Servicer shall
use commercially reasonable efforts to remit such late collections or principal prepayments to the Non-Lead Master Servicer within
one Business Day of receipt of properly identified funds but, in any event, the Master Servicer shall remit such amounts within
two Business Days of receipt of properly identified funds;


 


(viii)    the
Non-Lead Note Holder is an intended third-party beneficiary in respect of the rights afforded it under the Servicing Agreement
and each master servicer under a Non-Lead Servicing Agreement will be entitled to enforce the rights of the related Trustee with
respect to such Non-Lead Note under this Agreement and the Servicing Agreement;


 


(ix)       each
master servicer and special servicer under any Non-Lead Servicing Agreement shall be a third-party beneficiary of the Servicing
Agreement with respect to all provisions therein expressly relating to compensation, reimbursement or indemnification of such master
