Loan, by the Servicer in the Lead Securitization or by any Person appointed by the Lead Securitization Note Holder that is a “qualified
servicer” meeting the requirements of the Lead Securitization Servicing Agreement; provided, however, that

to perform such servicing in accordance with Accepted Servicing Practices and the provisions of this Agreement.


 


(g)

meaning of Section 860(G)(a)(9) of the Code, of the related REMIC), then, any provision of this Agreement to the contrary

of Section 860G(a)(8) of the Code and (iii) the related Holder may not modify, waive or amend any provision of the Mortgage
Loan, consent to or withhold consent from any action of the Mortgage Loan Borrowers, or exercise or refrain from exercising any
powers or rights which the related Holder 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 earliest startup day of any REMIC which includes the related
Note (or any portion of such Note). The Holders agree that the provisions of this Section 4(h) shall be effected by compliance
by the related Holder or its assignee with this Agreement or the Servicing Agreement or any other agreement which governs the
administration of the Mortgage Loan or such Holder’s interest therein. All costs and expenses of compliance with this Section

Following any period during which the terms of this Section 6 are in effect, in the event that the Mortgage Loan becomes

the terms of Section 5 hereof shall again be in effect, subject, however, to the terms of Section 7 hereof.


 


7.         
Workout. (a) Notwithstanding anything to the contrary contained herein, but subject to the terms and conditions of the
Servicing Agreement and Section 20 and Section 21 of this Agreement, and the obligation to act in accordance
with Accepted Servicing Practices, if any applicable 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 (or the Note Interest Rate for any Note) is reduced, (iii) payments of interest or principal on the Mortgage Loan are
waived, reduced or deferred (other than due solely to an extension of the Maturity Date (that is not a forbearance) pursuant to
an executed extension agreement between Lenders and the Mortgage Loan Borrowers, so long as no other modification under this Section
7 has occurred), or (iv) any other adjustment is made to any of the payment terms of the Mortgage Loan, all payments
to each Note A Holder pursuant to Section 5 and Section 6, as applicable, shall be made as though such
workout did not occur, with the payment terms of Note A remaining the same as they are on the Closing Date, and the full economic

with accrued interest thereon at the related Note Interest Rate and any other amounts due to such Note B Holder), and second,
pro rata by the Note A Holders (in each case up to the Note Principal Balance of the related A Note,

	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


together with accrued
interest thereon at the related Note Interest Rate, and any other amounts due to such Note A Holder). If the Mortgaged Properties
shall become an REO Property, the same shall be acquired, managed and operated in substantially the manner provided in the Servicing
Agreement, and the priority of distributions among the Note A Holder and the Note B Holder shall continue to be made in accordance
with the terms of Section 6 that would be applicable following the occurrence and during the continuation of a Triggering
Event of Default (whether or not the applicable Mortgage Loan Documents then remain in effect), with distributions on account
of scheduled interest payments being deemed to be Assumed Scheduled Payments (as such term shall be defined in the Servicing Agreement)
for such purpose.


 


(b)      
For purposes of determining the identity of the Controlling Holder (and not for any other purpose, including purposes of calculations
set forth in Section 5 and Section 6 hereof), Appraisal Reduction Amounts and Collateral Deficiency Amounts shall
be allocated first, to reduce the Note Principal Balances of the B Notes, pro rata, and then, to reduce the
Note Principal Balances of the A Notes, pro rata. The Lead Securitization Note Holder (or the Special Servicer on its behalf)
shall notify the Holders in writing of any Appraisal Reduction Amounts and Collateral Deficiency Amounts calculated with respect
to the Mortgage Loan and any allocation thereof to notionally reduce the Note Principal Balances of any Note.


 


8.

Securitization Note Holder shall cause the Servicer to establish and maintain the Collection Account. Each of the Holders hereby
directs the Servicer, in accordance with the priorities set forth in Section 5 and Section 6, as applicable,
and subject to the terms of this Agreement or the Servicing Agreement, as applicable, (i) to deposit into the applicable Collection
Account within two (2) Business Days after receipt of properly identified funds with respect to the Mortgage Loan and (ii) to
remit from the applicable Collection Account (x) for deposit or credit on the Remittance Date all payments received with respect
to and allocable to each A Note and B Note, by wire transfer to accounts maintained by each Holder and designated to the Servicer
in writing; provided that delinquent payments received by the Servicer after the related Remittance Date shall be remitted by
the Servicer to such accounts no later than the Business Day after the Determination Date; and (y) for such other purposes and
at such times as specified in this Agreement and the Servicing Agreement.


 


(b)         
If any Servicer holding or having distributed any amount received or collected in respect of any Note determines, or a court of
competent jurisdiction orders, at any time that any amount received or collected in respect of any Note must, pursuant to any
insolvency, bankruptcy, fraudulent conveyance, preference or similar law, be returned to the Mortgage Loan Borrowers or paid to
any Holder, any Servicer or any other Person, then, notwithstanding any other provision of this Agreement, such Servicer shall
not be required to distribute any portion thereof to the Holder of such Note, and such Holder, shall promptly on demand repay
to such Servicer the portion thereof which shall have been theretofore distributed to the related Holder, together with interest
thereon at such rate, if any, as such Servicer shall have been required to pay to the Mortgage Loan Borrowers, the Holders, any
other Servicer or such other Person with respect thereto, or, if the amount in question had been advanced by the Servicer, then
with interest thereon at the Advance Rate. Each 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 Servicer. The Servicer shall have the right to offset any amounts due hereunder from any Holder, with respect to the Mortgage
Loan against any future payments due to such Holder, as applicable, under the Mortgage Loan, provided, that the obligations
of each Holder under this Section 8 are separate and distinct obligations from one another, and in no event shall
any Servicer be permitted or required under the Servicing Agreement to enforce the obligations of any Holder against the other
Holders. The obligations of each Holder under this Section 8 constitute absolute, unconditional and continuing obligations
and each Servicer shall be deemed a third party beneficiary of these provisions.

together with interest thereon at the Advance Rate, if applicable, shall be paid to the Holders as provided in Section 5 and Section
6 hereof.

amounts recovered with respect to the Mortgage Loan or the Mortgaged Properties to the extent provided in this Agreement.


 


(c)          
If any party to the Lead Securitization Servicing Agreement or any Non-Lead Securitization Servicing Agreement makes a P&I

party solely as provided under the terms of this Agreement and the Lead Securitization Servicing Agreement or Non-Lead Securitization
Servicing Agreement, as applicable.


 


(d)         
The Lead Securitization Servicing Agreement shall provide that Penalty Charges and any interest accrued at the Mortgage Default

shall deliver a Notice of Foreclosure/DIL (stating that it intends to accept a deed-in-lieu of foreclosure) to the Note B Holder
and the Note B Holder shall have the option, within ten (10) Business Days from the date it receives such Notice of Foreclosure/DIL,

that it has delivered notice within such time period, to consummate the purchase option on a Repurchase Date (as defined below)
to occur no later than thirty (30) days from the day it received the Notice of Foreclosure/DIL from the Servicer; provided,
that such thirty (30) days may be extended at the option of the Note B Holder for an additional thirty (30) days upon payment
to the Lead Securitization Note Holder (or the Servicer on its behalf) of a $5 million non-refundable cash deposit if the Note
B Holder provides evidence reasonably satisfactory to the Lead Securitization Note Holder (or the Servicer on its behalf) that
it is diligently and expeditiously proceeding to consummate its purchase of each A Note, (c) the modification of the Mortgage
Loan Documents effected in accordance herewith and with the terms of the Servicing Agreement (and subject to the approval rights
of the Directing Holder and the consultation rights of the Non-Controlling Holder set forth herein and therein) and (d) the date
that is ninety (90) days after the Directing Holder’s receipt of the Repurchase Option Notice, to purchase each A Note for
the applicable Defaulted Mortgage Loan Purchase Price, and upon the delivery of the Note B Holder Repurchase Notice to each Note
A Holder (or the Servicer on its behalf), each Note A Holder (or the Servicer on its behalf) shall sell and the Note B-1 Holder,

	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


option contemplated by this Section 11(a),
the Lead Securitization Note Holder (or the Servicer or Trustee on its behalf) shall deliver all original Mortgage Loan Documents
and other applicable materials in its possession to the applicable Note B Holder or its designee. The foregoing rights of the
Note B Holders shall be in addition to any rights such Person may have to purchase each A Note pursuant to the Servicing Agreement.
Notwithstanding the foregoing, if either of the Mortgage Loan Borrowers or any Mortgage Loan Borrower Related Party is a Note
B Holder (or holds a majority interest in a B Note), such Note B Holder shall not have the right to exercise the purchase option
set forth in this Section 11(a).


 


Notwithstanding
anything to the contrary contained in this Section, during the period in which any portion of the Mortgage Loan is subject to
purchase by Note B Holder pursuant to this Section, the Mortgage Loan shall continue to be serviced by the applicable Servicer
in accordance with Accepted Servicing Practices.


 


(b)         
Cure Rights. In the event any monetary default beyond applicable notice and grace periods or non-monetary default beyond
applicable notice and grace periods shall exist with respect to the Mortgage Loan, then, upon notice from the Lead Securitization
Note Holder (or the Servicer on its behalf) (a “Cure Option Notice”) of the occurrence of such default beyond
applicable notice and grace periods (which notice the Lead Securitization Note Holder (or the Servicer on its behalf) shall promptly
give to the Note B Holder upon receipt of knowledge thereof), each Note B Holder shall have the right, exercisable by each Note
B Holder giving written notice of its intent to cure a default within five (5) Business Days after receipt of the Cure Option
Notice, to cure such default (and if each of the Note B-1 Holder, the Note B-2 Holder, the Note B-3 Holder or the Note B-4 Holder,
or any combination thereof, provide such notice, then such Note B Holders collectively, on a pro rata basis shall have
the right to cure such default); provided, in the event a Note B Holder has elected to cure any default, the default must
be cured by such Note B Holder within, in the case of a monetary default, ten (10) Business Days after receipt of such Cure Option
Notice and, in the case of a non-monetary default, thirty (30) days after receipt of such Cure Option Notice. If a Note B Holder
is attempting to cure a non-monetary default, the foregoing cure period of thirty (30) days may be extended for an additional
sixty (60) days (for a total of up to ninety (90) days), but only for so long as (i) such Note B Holder is diligently and expeditiously
proceeding to cure such non-monetary default, (ii) such Note B Holder makes all Cure Payments that it is permitted to make in
accordance with this Section, (iii) such non-monetary default is not the result of a bankruptcy of the Mortgage Loan Borrowers
or other insolvency related event, and no bankruptcy commences or other insolvency related event occurs during the period that
such Note B Holder is otherwise permitted to cure a non-monetary default in accordance with this Section and (iv) there is no
material adverse effect on the Mortgage Loan Borrowers, the Mortgaged Properties or the value of the Mortgage Loan as a result
of such non-monetary default or the attempted cure thereof.


 


If
a Note B Holder elects to cure a default that can be cured by the payment of money (each such payment, a “Cure Payment”),
such Note B Holder shall make such Cure Payment as directed by the Lead Securitization Note Holder (or the Servicer on its behalf)
and each such Cure Payment shall include all costs, expenses, losses, liabilities, obligations, damages, penalties, and disbursements
imposed on, incurred by or asserted against each Note A Holder (including,


 



    
	46 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


without limitation, all unreimbursed Advances (without
regard to whether such Advance would be a Nonrecoverable Advance) and any interest charged thereon at the Advance Rate, and any
unpaid Special Servicing Fees with respect to the Mortgage Loan, but excluding any default interest and Penalty Charges) related
to the default and incurred during the period of time from the expiration of the grace period for such default under the Mortgage
Loan until such Cure Payment is made or such other cure is otherwise effected.


 


The
right of a Note B Holder to reimbursement of any Cure Payment shall be as set forth in Section 5 and Section 6,
as applicable. So long as a default exists that is being cured by a Note B Holder pursuant to this Section 11(b) and
the cure period has not expired and such Note B Holder is permitted to cure under the terms of this Section 11(b),
the Lead Securitization Note Holder (or the Servicer on its behalf) and the Trustee shall not treat such default as a default
or a Triggering Event of Default (i) for purposes of Section 5 or Section 6; (ii) for purposes of accelerating
the Mortgage Loan, modifying, amending or waiving any provisions of the Mortgage Loan Documents or commencing proceedings for
foreclosure or the taking of title by deed-in-lieu of foreclosure or other similar legal proceedings with respect to the Mortgaged
Properties; or (iii) for purposes of treating the Mortgage Loan as a Specially Serviced Mortgage Loan; provided that such
limitations shall not prevent the Lead Securitization Note Holder (or the Servicer on its behalf) or the Trustee from sending
notices of the default to the Mortgage Loan Borrowers or any related guarantor or making demands on the Mortgage Loan Borrowers
or any related guarantor or from collecting default interest or late payment charges from the Mortgage Loan Borrowers. Notwithstanding
anything to the contrary contained in this Section 11(b), (A) a Note B Holder’s right to cure a monetary default
or non-monetary default shall be limited to six (6) Cure Events over the life of the Mortgage Loan and (B) no single Cure Event
may exceed four (4) consecutive months. For the avoidance of doubt, it is intended that if a single Event of Default is cured
for four consecutive months, that same Event of Default may not be cured in the succeeding (fifth) month, a Note B Holder would
be permitted to cure a different Event of Default in such succeeding (fifth) month. As used herein, “Cure Event”
means a Note B Holder’s exercise of cure rights, whether for one (1) month or for consecutive months in the aggregate (and,
in such case, such cure for such consecutive months shall constitute one (1) Cure Event). Cure Events in addition to the number
of Cure Events permitted under this Section 11(b) shall only be permitted with the consent of the Lead Securitization Note
Holder (or the Servicer on its behalf) or, at any time that the Mortgage Loan is included in the Lead Securitization, the Special
Servicer.

16.      
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 the arrangement between any one or more Holders, on the one hand, and any one or more other
Holders, on the other hand, a partnership, association, joint venture or other entity. No Holder shall have any obligation whatsoever
to offer to any other Holder the opportunity to purchase notes or participation interests relating to any future loans originated
by such Holder or its Affiliates, and if such Holder chooses in its sole discretion to offer to one or more other Holders the
opportunity to purchase notes or any participation 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. No Holder
shall have any obligation whatsoever to purchase from one or more other Holders any notes or participation interests in any future
loans originated by the other Holder or its respective Affiliates.


 


17.       
Not a Security. None of the Notes shall be deemed to be a security within the meaning of the Securities Act of 1933 or
the Securities Exchange Act of 1934.


 


18.       
Transfer of Notes. (a) Each Holder agrees that it will not sell, assign, transfer, pledge, syndicate, hypothecate, contribute,
encumber or otherwise dispose of all or any portion of its respective Note (a “Transfer”) except to a Qualified
Institutional Lender. Promptly after any Transfer (other than any Transfer between Initial Holders or any Transfer by an Initial
Holder to a Securitization Trust), non-transferring Holders shall be provided with (x) a representation from the related transferee
or the applicable Holder certifying that such transferee is a Qualified Institutional Lender (except in the case of a Transfer
in accordance with the immediately following sentence) and (y) a copy of an assignment and assumption agreement whereby such transferee
assumes all of the obligations of the applicable Holder hereunder with respect to such Note thereafter accruing and agrees to
be bound by the terms of this Agreement. If a Holder intends to Transfer its respective Note, or any portion thereof, to an entity
that is not a Qualified Institutional Lender, it must first (a) obtain the consent of each non-transferring Holder and (b) if
any such non-transferring Holder’s Note is held in a Securitization Trust, provide each of the applicable engaged Rating
Agencies for such Securitization Trust with a Rating Agency Confirmation. Notwithstanding the foregoing, without each non-transferring
Holder’s prior consent (which will not be unreasonably withheld), and, if any non-transferring Holder’s Note is held
in a Securitization Trust, until a Rating Agency Confirmation is provided to each engaged Rating Agency for such Securitization
Trust, no Holder shall Transfer all or any portion of its Note (or a participation interest in such Note) to the Mortgage Loan
Borrowers or a Mortgage Loan Borrower Related Party and any such Transfer shall be absolutely null and void and shall vest no
rights in the purported transferee. The transferring Holder agrees that it shall pay the expenses of any non-transferring Holder
(including all expenses of the Master Servicer, the Special Servicer and the Trustee) and all expenses relating to any Rating
Agency Confirmation in connection with any such Transfer. Notwithstanding the foregoing, each Holder shall have the right, without
the need to obtain the consent of any other Holder or of any other Person or having to provide any Rating Agency Confirmation,
to Transfer 49% or less (in the aggregate) of its beneficial interest in a Note to an entity that is not the Mortgage Loan Borrowers
or a Mortgage Loan Borrower Related Party. None of the provisions of this Section 18(a) shall apply in the case of (1)
a sale of the Lead Securitization Notes together with all of the


 



    
	51 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


Non-Lead Securitization Notes, in accordance with the terms and
conditions of the Lead Securitization Servicing Agreement, (2) a transfer by the Special Servicer, in accordance with the terms
and conditions of the Lead Securitization Servicing Agreement, of the Mortgage Loan or the Mortgaged Properties, upon the Mortgage
Loan becoming a Defaulted Loan, to a single member limited liability or limited partnership, 100% of the equity interest in which
is owned directly or indirectly, through one or more single member limited liability companies or limited partnerships, by the
Lead Securitization Trust, or (3) the Transfer of any securities issued by a Securitization Trust.


 


(b)      
In the case of any Transfer of a participation interest in any of the Notes, (i) the respective Holders’ obligations under
this Agreement shall remain unchanged, (ii) such Holders shall remain solely responsible for the performance of such obligations,
and (iii) the Lead Securitization Note Holder and any Persons acting on its behalf shall continue to deal solely and directly
with such Holder in connection with such Holder’s rights and obligations under this Agreement and the Lead Securitization
Servicing Agreement, and all amounts payable hereunder shall be determined as if such Holder had not sold such participation interest.


 


(c)       
Notwithstanding any other provision hereof, any Holder may pledge (a “Pledge”) its Note to any entity (other
than the Mortgage Loan Borrowers or any Affiliate thereof) which has extended a credit facility to such Holder and that is either
a Qualified Institutional Lender or a financial institution whose long-term unsecured debt is rated at least “A” (or
the equivalent) or better by each applicable Rating Agency (or, if not rated by an applicable Rating Agency, an equivalent (or
higher) rating from any two of Fitch, Moody’s and S&P) (a “Note Pledgee”), on terms and conditions
set forth in this Section 18(c), it being further agreed that a financing provided by a Note Pledgee to a Holder or any
person which Controls such Note that is secured by its Note and is structured as a repurchase arrangement, shall qualify as a
“Pledge” hereunder, provided that a Note Pledgee which is not a Qualified Institutional Lender may not take title
to the pledged Note without a Rating Agency Confirmation. Upon written notice by the applicable Holder to each other Holder and
any Servicer that a Pledge has been effected (including the name and address of the applicable Note Pledgee), each other Holder
agrees to acknowledge receipt of such notice and thereafter agrees: (i) to give 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; (ii)
to allow such Note Pledgee a period of ten (10) days to cure a default by the pledging Holder in respect of its obligations to
each 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 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; (iv) that such other Holder shall give to such
Note Pledgee copies of any notice of default under this Agreement simultaneously with the giving of same to the pledging Holder;
(v) that such other Holder 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 such other Holder; and (vi) that, upon written
notice (a “Redirection Notice”) to each other Holder and any Servicer by such Note Pledgee that the pledging
Holder is in default, beyond any applicable cure periods, under the pledging Holder’s obligations to such Note Pledgee pursuant
to the applicable


 



    
	52 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


credit agreement 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 Notice is withdrawn or rescinded by such Note Pledgee, Note Pledgee shall
be entitled to receive any payments that any Holder or Servicer would otherwise be obligated to pay to the pledging Holder from
time to time pursuant to this Agreement or the Lead Securitization Servicing Agreement. Any pledging Holder hereby unconditionally
and absolutely releases each other Holder and any Servicer from any liability to the pledging Holder on account of such other
Holder’s or Servicer’s compliance with any Redirection Notice believed by any Servicer or such other Holder to have
been delivered by a Note Pledgee. Note Pledgee shall be permitted to exercise fully its rights and remedies against the pledging
Holder to such Note Pledgee (and accept an assignment in lieu of foreclosure as to such collateral), in accordance with applicable
law and this Agreement. In such event, the Holders and any Servicer shall recognize such Note Pledgee (and any transferee other
than the Mortgage Loan Borrowers or any Affiliate thereof which is also a Qualified Institutional Lender at any foreclosure or
similar sale held by such Note Pledgee or any transfer in lieu of foreclosure), and its 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 Institutional
Lender 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 18(c) shall remain effective as to any Holder (and any Servicer) unless and until such
Note Pledgee shall have notified any such Holder (and any Servicer, as applicable) in writing that its interest in the pledged
Note has terminated.


 


(d)      
Notwithstanding any provisions herein to the contrary, if a conduit (“Conduit”) which is not a Qualified Institutional
Lender provides financing to a Holder then such Holder shall have the right to grant a security interest in its Note to such Conduit
notwithstanding that such Conduit is not a Qualified Institutional Lender, if the following conditions are satisfied:


 


(i)       
The loan (the “Conduit Inventory Loan”) made by the Conduit to such Holder to finance the acquisition and holding
of its Note requires a third party (the “Conduit Credit Enhancer”) to provide credit enhancement;


 


(ii)      
The Conduit Credit Enhancer is a Qualified Institutional Lender;


 


(iii)     
Such Holder pledges its interest in its Note to the Conduit as collateral for the Conduit Inventory Loan;


 


(iv)    
The Conduit Credit Enhancer and the Conduit agree that, if such Holder defaults under the Conduit Inventory Loan, or if the Conduit
is unable to refinance its outstanding commercial paper even if there is no default by such Holder, the Conduit Credit Enhancer
will purchase the Conduit Inventory Loan from the Conduit, and the Conduit will assign the Pledge of such Holder’s Note
to the Conduit Credit Enhancer; and

	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


(v)      
Unless the Conduit is in fact then a Qualified Institutional Lender, the Conduit will not without obtaining a Rating Agency Confirmation
from each Rating Agency have any greater right to acquire the interests in the Note pledged by such Holder, by foreclosure or
otherwise, than would any other purchaser that is not a Qualified Institutional Lender at a foreclosure sale conducted by a Note
Pledgee.


 


19.      
Other Business Activities of the Holders. Each of the Holders acknowledges that the other Holders may make loans or otherwise
extend credit to, and generally engage in any kind of business with, any Affiliate of the Mortgage Loan Borrowers (“Mortgage
Loan Borrower Related Parties”), and receive payments on such other loans or extensions of credit to the Mortgage Loan
Borrower Related Parties and otherwise act with respect thereto freely and without accountability in the same manner as if this
Agreement and the transactions contemplated hereby were not in effect.


 


20.      
Exercise of Remedies by the Servicer.


 


(a)      
Each of the Holders acknowledges that, subject to the terms of this Agreement (including without limitation, the Controlling Holder’s
rights under Section 21 hereof) and the Servicing Agreement, (i) the Lead Securitization Note Holder (or any Servicer or
Trustee (if any) on its behalf) may exercise or refrain from exercising any rights that such Lead Securitization Note Holder (or
such Servicer or Trustee (if any)) may have hereunder or under the Servicing Agreement in a manner that may be adverse to the
interests of the other Holders, so long as such actions are in accordance with Accepted Servicing Practices and the other terms
of this Agreement, (ii) the Lead Securitization Note Holder shall have no liability whatsoever to the other Holders as a result
of such Lead Securitization Note Holder’s (or any Servicer’s or Trustee’s) exercise of such rights or any omission
by such Lead Securitization Note Holder (or any Servicer or Trustee) to exercise such rights, except as expressly provided herein
or for acts or omissions that are taken or omitted to be taken by such Lead Securitization Note Holder that constitute the gross
negligence or willful misconduct of such Lead Securitization Note Holder or a breach of this Agreement, and (iii) the Servicer
and the Special Servicer shall (and shall be required under the Servicing Agreement to) service and administer the Mortgage Loan
on behalf of each Note A Holder and each Note B Holder (as a collective whole) in accordance with Accepted Servicing Practices,
taking into account the interests of each Note A Holder and each Note B Holder; but in all cases giving due consideration to the
fact that each B Note is subject and subordinate to each A Note in accordance with the terms of this Agreement. Each Note A Holder
and each Note B Holder agree that the Servicer, to the extent consistent with the terms of this Agreement (including, without
limitation, Section 21) and from and after the Lead Securitization Date subject to and in accordance with the Servicing
Agreement, shall have the sole and exclusive authority (in each case, subject to the Accepted Servicing Practices and the terms
and conditions set forth in this Agreement, and the rights of any Controlling Holder) 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
(i) to modify or waive any of the terms of the Mortgage Loan Documents, (ii) to consent to any action or failure to act by the
Mortgage Loan Borrowers or any party to the Mortgage Loan Documents, (iii) to vote all claims with respect to the Mortgage Loan
in any bankruptcy, insolvency or other similar


 



    
	54 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


 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 in all cases acting in accordance with Accepted Servicing Practices and the terms
of this Agreement and the Servicing Agreement, and except as otherwise expressly provided in this Agreement and the Servicing
Agreement, the other Holders shall have no voting, consent or other rights whatsoever with respect to the Lead Securitization
Note Holder’s or Servicer’s administration of, or exercise of its rights and remedies with respect to, the Mortgage
Loan. Each Holder agrees that it shall have no right to, and hereby presently and irrevocably assigns and conveys to the Lead
Securitization Note Holder and the Servicer and the Special Servicer the rights, if any, that such Holder has (i) to declare or
cause the Lead Securitization Note Holder or the Servicer to declare an Event of Default under the Mortgage Loan (ii) to exercise
any remedies with respect to the Mortgage Loan, including, without limitation, filing or causing the Lead Securitization Note
Holder or the Servicer to file any bankruptcy petition against the Mortgage Loan Borrowers or (iii) to vote any claims with
respect to the Mortgage Loan (including claims arising from any one or more Notes) in any bankruptcy, insolvency or similar type
of proceeding of the Mortgage Loan Borrowers. Each Holder shall, from time to time, execute such documents as the Lead Securitization
Note Holder, the Servicer or the Special Servicer shall reasonably request to evidence such assignment with respect to the rights
described in clause (iii) of the preceding sentence. Except when acting in the capacity of trustee or paying agent, the Lead
Securitization Note Holder (or the Servicer or the Special Servicer acting on behalf of such Lead Securitization Note Holder)
shall not have any fiduciary duty to the other Holders in connection with the administration of the Mortgage Loan but shall in
all events be obligated to act in accordance with Accepted Servicing Practices. Each Holder expressly and irrevocably waives for
itself and any Person claiming through or under such Holder any and all rights that it may have under Section 1315 of the
New York Real Property Actions and Proceedings Law or the provisions of any similar law that purports to give a junior noteholder,
mortgagee or loan participant the right to initiate any loan enforcement or foreclosure proceedings.


 


(b)      
Notwithstanding anything to the contrary contained herein, the exercise by the Lead Securitization Note Holder (or any Servicer
or the Trustee (if any) acting on its behalf) of its rights under this Section 20 shall be subject in all respects
to any sections of the Servicing Agreement governing REMIC administration, and in no event shall the Lead Securitization
Note Holder (or any Servicer or the Trustee (if any) acting on its behalf) be permitted to take any action or refrain from taking
any action which would violate the laws of any applicable jurisdiction, breach the Mortgage Loan Documents, violate Accepted Servicing
Practices or violate any other provisions of the Servicing Agreement or cause the arrangement evidenced hereby not to be treated
as a “grantor trust” for Federal income tax purposes. The Lead Securitization Note Holder (or any Servicer or the
Trustee (if any) acting on its behalf) shall exercise such rights and powers described in this Section 20 on the understanding
that the Lead Securitization Note Holder (or any Servicer or the Trustee (if any) acting on its behalf) shall administer the Mortgage
Loan in a manner consistent with the Servicing Agreement and this Agreement, provided that neither the Lead Securitization
Note Holder nor any Servicer or the


 



    
	55 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


 Trustee (if any) acting on its behalf shall be liable to the other Holders with respect to
anything the Lead Securitization Note Holder or such Servicer or the Trustee (if any) may do or omit to do in relation to the
Mortgage Loan, other than as expressly set forth in this Agreement. Without limiting the generality of the foregoing, the Lead
Securitization Note Holder and any Servicer or the Trustee (if any) acting on its behalf may rely on the advice of legal counsel,
accountants and other experts (including those retained by the Mortgage Loan Borrowers) and upon any written communication or
telephone conversation which the Lead Securitization Note Holder or such Servicer or the Trustee (if any) believes to be genuine
and correct or to have been signed, sent or made by the proper Person.


 


(c)       
If title to the Mortgaged Properties are acquired for the benefit of the Holders in foreclosure, by deed-in-lieu of foreclosure
or upon abandonment or reclamation from bankruptcy, the deed or certificate of sale shall be taken in the name of the Lead Securitization
Note Holder or its nominee (which shall not include any Servicer) on behalf of the Holders. The Servicer, on behalf of the Holders,
shall dispose of any REO Property utilizing reasonable best efforts, consistent with Accepted Servicing Practices, to maximize
the proceeds of such disposal to the Holders (as a collective whole) if and when such Servicer determines, consistent with Accepted
Servicing Practices, that such disposal would be in the best economic interest of the Holders (as a collective whole). The Servicer
shall (and shall be required under the Servicing Agreement to) manage, conserve, protect and operate each REO Property for the
Holders solely for the purpose of its prompt disposition and sale in accordance with Accepted Servicing Practices.


 


(d)      
The Servicer shall have full power and authority, subject only to the specific requirements and prohibitions of this Agreement
(including the rights of the Controlling Holder), to do any and all things in connection with any REO Property as are consistent
with Accepted Servicing Practices and the terms of this Agreement, all on such terms and for such period as such Servicer deems
to be in the best interests of Holders (as a collective whole) and, in connection therewith, such Servicer shall only agree to
the payment of management fees that are consistent with general market standards or to terms that are more favorable to the Holders.
The Servicer shall (and shall be required under the Servicing Agreement to) segregate and hold all revenues received by it with
respect to any REO Property separate and apart from its own funds and general assets and shall establish and maintain with respect
to any REO Property a segregated custodial account (each, an “REO Account”). The Servicer shall (and shall
be required under the Servicing Agreement to) deposit or cause to be deposited in the REO Account within two Business Days after
receipt all revenues received by it with respect to any REO Property (other than Liquidation Proceeds, which shall be remitted
to the Collection Account), and shall withdraw therefrom funds necessary for the proper operation, management and maintenance
of such REO Property and for other Costs with respect to such REO Property, including:


 


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


 


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


 






    
	56 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


(iii)     
all ground rents in respect of any REO Property;


 


(iv)     
all costs and expenses reasonable and necessary to protect, maintain, manage, operate, repair and restore any REO Property; and


 


(v)      
to the extent that such REO Proceeds are insufficient for the purposes set forth in clauses (i) through (iv) above and the
Servicer has provided written notice of such shortfall to the Holders of the necessity to take actions pursuant to this subsection (d),
any expenditure associated with such actions taken by the Servicer shall be payable by the Holders at their option pursuant to
Section 9.


 


(e)      
The Servicer shall contract with an independent contractor, the fees and expenses of which shall be an expense of the Holders
and payable out of REO Proceeds, for the operation and management of any REO Property, within forty-five (45) days after the Holders’
acquisition thereof (unless the Holders approve otherwise), provided that:


 


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


 


(ii)      
any such contract shall require, or shall be administered to require, that the independent contractor pay all costs and expenses
incurred in connection with the operation and management of such REO Property, including those listed above, and remit all related
revenues (net of such costs and expenses) to the Servicer as soon as practicable, but in no event later than thirty (30) days
following the receipt thereof by such independent contractor;


 


(iii)     
none of the provisions of this subsection (e) relating to any such contract or to actions taken through any such independent
contractor shall be deemed to relieve the Servicer of any of its duties and obligations to the Holders or the Lead Securitization
Note Holder on behalf of the Holders with respect to the operation and management of any such REO Property; and


 


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


 


(f)      
The 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 such Servicer by such independent contractor, and nothing in this
Agreement shall be deemed to limit or modify such indemnification. When and as necessary, the Servicer shall send to the Holders
a statement prepared by the 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 in respect of, any REO Property.

(g)      
With respect to the Specially Serviced Mortgage Loan or REO Property, which the Servicer has determined to sell in accordance
with Accepted Servicing Practices, the Servicer shall deliver to the Holders an officers’ certificate to the effect that,
the Servicer has determined to sell the Specially Serviced Mortgage Loan or REO Property in accordance with this subsection (g).
The Servicer may then offer to sell to any Person the Specially Serviced Mortgage Loan which is in default or the REO Property
(and shall on a monthly basis advise the Holders in writing of the status of the Specially Serviced Mortgage Loan or REO Property)
or, subject to the following sentence, purchase the Specially Serviced Mortgage Loan or REO Property (in each case at the Defaulted
Mortgage Loan Purchase Price), but shall, in any event, so offer to sell the REO Property no later than the time determined by
the Servicer to be sufficient to result in the sale of the REO Property within the period specified in the REMIC Provisions. The
Servicer shall deliver such officers’ certificate and give the Holders not less than ten (10) Business Days’ prior
written notice of its intention to sell the Specially Serviced Mortgage Loan or REO Property, in which case the Servicer shall
accept the highest offer received from any Person for the Specially Serviced Mortgage Loan or the REO Property in an amount at
least equal to the Defaulted Mortgage Loan Purchase Price or, at its option, if it has received no offer at least equal to the
Defaulted Mortgage Loan Purchase Price therefor, purchase the Specially Serviced Mortgage Loan or REO Property at the Defaulted
Mortgage Loan Purchase Price.


 


(h)      
In the absence of any such offer at the Defaulted Mortgage Loan Purchase Price, or purchase by the Servicer at the Defaulted Mortgage
Loan Purchase Price, such Servicer shall accept the highest offer received from any Person that is determined by such Servicer
to be a fair price for the Specially Serviced Mortgage Loan or REO Property; provided, that the Lead Securitization Note
Holder (or the Servicer, if the Servicer or any Affiliate of the Servicer is not an offeror) shall be entitled to engage, at the
expense of the Holders, an Appraiser to determine whether the highest offer is a fair price. Notwithstanding anything to the contrary
herein, neither the Mortgage Loan Borrowers nor any Mortgage Loan Borrower Related Party may make an offer or purchase the Specially
Serviced Mortgage Loan or the REO Property pursuant hereto.


 


(i)       
The Servicer shall not be obligated by either of the foregoing paragraphs or otherwise to accept the highest offer if the Servicer
determines, in accordance with Accepted Servicing Practices, that rejection of such offer would be in the best interests of the
Holders as a collective whole. In addition, the Servicer may accept a lower offer if it determines, in accordance with Accepted
Servicing Practices, that acceptance of such offer would be in the best interests of the Holders as a collective whole (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 Servicer or an Affiliate of the Servicer.
The Servicer shall in no event sell the Specially Serviced Mortgage Loan or the REO Property other than for cash.


 


(j)       
Subject to the other provisions of this Section 20, the Servicer shall act on behalf of the Holders in negotiating
and taking other action necessary or appropriate in connection with the sale of the Specially Serviced Mortgage Loan or REO Property,
including the collection of all amounts payable in connection therewith. Any sale of the Specially Serviced


 



    
	58 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


Mortgage Loan or REO
Property shall be without recourse to, or representation or warranty by, any Servicer or any Holder, and, if such sale is consummated
in accordance with the duties of the Servicer pursuant to the terms of this Agreement, no such Person who so performed shall have
any liability to any Holders with respect to the purchase price therefor accepted by the Servicer.


 


(k)      
The proceeds of any sale of the Specially Serviced Mortgage Loan or REO Property after deduction of the direct out-of-pocket expenses
of such sale incurred in connection therewith shall be promptly, and in any event within one (1) Business Day (or, if received
after 3:00 p.m. Eastern time, two (2) Business Days) following receipt of properly identified funds, deposited in the Collection
Account. Within thirty (30) days after the sale of the REO Property, the Servicer shall provide to the Holders a statement of
accounting for the REO Property, including without limitation, (i) the date of disposition of the REO Property, (ii) the gross
sales price, the selling and other expenses and the net sales price, (iii) accrued interest on the Note A Principal Balance at
the applicable Note Interest Rate for each A Note, and on the Note B Principal Balance at the applicable Note Interest Rate for
each Note B, in each case calculated from the date of acquisition to the disposition date, and (iv) such other information as
the Holders may reasonably request. The Servicer shall file information returns regarding the abandonment or foreclosure of Mortgaged
Properties with the Internal Revenue Service at the time and in the manner required by the Code.


 


(l)       
The provisions of subsections (c) through (k) of this Section 20 shall be of no further force and effect from
and after the Lead Securitization Date, and the analogous provisions of the Lead Securitization Servicing Agreement shall control.


 


21.      
Certain Powers of the Controlling Holder.


 


This
Section 21 shall apply during the term of this Agreement; provided that from and after the Lead Securitization Date, (y)
Section 21(c) and (d) shall be of no further force and effect and the analogous provisions of the Lead Securitization
Servicing Agreement shall control, and (z) Section 21(j), (k) and (l) shall be of no further force and effect.


 


The
following provisions shall apply during the term of this Agreement:


 


(a)       
The Controlling Holder shall be entitled to appoint (or act as) a “directing lender” (the “Directing Holder”)
with respect to the Mortgage Loan and to exercise the rights and powers granted to the Directing Holder and the Controlling Holder
hereunder and under the Servicing Agreement (such designation to be made by written notice to the Lead Securitization Note Holder
(or the Servicer on its behalf)); provided, that if the Mortgage Loan Borrowers or any Mortgage Loan Borrower Related Party owns
any portion of a B Note, the ownership interests of such Person shall be deemed to equal zero for the purposes of determining
which owners can vote to elect the Directing Holder, and provided, further, that in no event may the Mortgage Loan Borrowers or
any Mortgage Loan Borrower Related Party serve as the Directing Holder. Subject to the Lead Securitization Servicing Agreement,
such designation shall remain in effect until it is revoked by the Controlling Holder by a writing delivered to each of the other
parties hereto.

	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


(b)      
Notwithstanding anything to the contrary contained herein (but subject to Section 21(d)), the Lead Securitization Note Holder
(or the Servicer on its behalf) shall, prior to taking any Major Decision, be required to notify in writing the Directing Holder
of any proposal to take any of such actions (and to provide the Directing Holder with such information requested by such Directing
Holder as may be necessary in the reasonable judgment of such Directing Holder in order to make a judgment) and to receive the
written approval of the Directing Holder (which approval may be withheld in its sole discretion);


 


(c)      
If the Directing Holder fails to notify the Lead Securitization Note Holder (or the Servicer on its behalf) of its approval or
disapproval of any such Major Decision within ten (10) Business Days after delivery to the Directing Holder by the Lead Securitization
Note Holder (or the Servicer on its behalf) of written notice (“Action Notice”) of such a Major Decision (which
notice shall contain a legend, in capitalized, bold-faced type containing the following statement as the top of the first page:
“THIS IS A REQUEST FOR MAJOR DECISION APPROVAL. IF THE DIRECTING HOLDER FAILS TO APPROVE OR DISAPPROVE THE ENCLOSED MAJOR
ACTION WITHIN TEN (10) BUSINESS DAYS, SUCH MAJOR DECISION WILL BE DEEMED APPROVED BY THE DIRECTING HOLDER”) together with
any information requested by the Directing Holder pursuant to Section 21(b) or this Section 21(c), then if the Directing
Holder fails to approve or reject the Major Decision within such ten (10) Business Day period, the Directing Holder’s approval
will be deemed to have been given for such Major Decision (provided, that if the Directing Holder has failed to notify the Lead
Securitization Note Holder (or the Servicer on its behalf) of its approval or disapproval of any such Major Decision within five
(5) Business Days following the delivery of the related Action Notice together with any information requested by the Directing
Holder pursuant to Section 21(b) or this Section 21(c), the Lead Securitization Note Holder (or the Servicer on
its behalf) will be required to promptly provide to the Directing Holder a second Action Notice bearing the same legend as the
first Action Notice). Notwithstanding the foregoing, any amounts funded by any Holder under the Mortgage Loan Documents as a result
of (1) the making of any protective Advances or (2) interest accruals or accretions and any compounding thereof (including default
interest) with respect to the Notes shall not at any time be deemed to require prior notice to the Directing Holder (except as
otherwise expressly required by this Agreement) or otherwise contravene this subsection. To the extent the Mortgage Loan Borrowers
request or the Servicer or Special Servicer structures, as part of a workout or otherwise, an extension of the Mortgage Loan for
two or more years beyond the Maturity Date, the Servicer or Special Servicer, as applicable, shall obtain the prior written consent
of the Lead Securitization Note Holder (in the same manner as the Directing Holder) in addition to the consent of the Directing
Holder. The provisions of this Section 21(c) shall be of no further force and effect from and after the Lead Securitization
Date, and the analogous provisions of the Servicing Agreement shall control.


 


(d)      
With respect to any proposed action requiring consultation with or approval of the Directing Holder pursuant to Section 21(b),
the Lead Securitization Note Holder (or the Servicer on its behalf) shall prepare a summary of such proposed action and an analysis
of whether or not such action is reasonably likely to produce a greater recovery on a present value basis than not taking such
action, setting forth the basis on which the Lead Securitization


 



    
	60 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


Note Holder (or the Servicer on its behalf) made such determination,
and shall promptly provide to each Holder copies of such summary and any other material documents and items reasonably necessary
to make such determination by hard copy or electronic means on a timely basis. If any such proposed action is disapproved by the
Directing Holder, the Servicer shall propose an alternate action (based on any counter-proposals received from the Directing Holder,
to the extent such counter-proposal is consistent with Section 21(d) or, if no such counter-proposal is received by
the Servicer when the disapproval of the Directing Holder is delivered to the Servicer, then based on any alternate course of
action that the Lead Securitization Note Holder (or the Servicer on its behalf) may deem appropriate) until the approval of the
Directing Holder is obtained; provided that if the Servicer and Directing Holder do not agree on a proposed course of action within
sixty (60) days after the date on which the Servicer first proposed a course of action and the counter-proposals received from
the Directing Holder would, in the judgment of the Special Servicer, be permitted to be ignored by the Special Servicer in accordance
with clause (d) below, then after giving due consideration (subject to Section 21(d) hereof) to the alternatives and
counterproposals, if any, provided by the Directing Holder the Lead Securitization Note Holder (or the Servicer on its behalf)
shall take such action as it deems appropriate in accordance with Accepted Servicing Practices. Notwithstanding the foregoing,
if in accordance with Accepted Servicing Practices, (i) the Lead Securitization Note Holder (or the Servicer on its behalf) determines
that emergency action is necessary to protect the Mortgaged Properties or the interests of the Holders (as a collective whole)
at a time earlier than the time that such Servicer would otherwise be entitled to take such action pursuant to this Section
21(d) or otherwise under this Agreement and (ii) such action requires consultation with and/or consent of the Directing Holder,
then it shall contact the Directing Holder (by telephone, email or fax) promptly and shall discuss (unless the Directing Holder
and the Lead Securitization Note Holder, as applicable, shall fail to respond in a reasonable time frame under the circumstances)
the proposed action with such Directing Holder and the Lead Securitization Note Holder, as applicable, and, if the consent of
the Directing Holder would ordinarily be required, attempt to reach agreement within the revised time frame prior to taking the
proposed action, but shall be entitled to take the necessary emergency action within the necessary time frame regardless of whether
it has been able to contact or obtained the agreement of the Directing Holder and the Lead Securitization Note Holder. If such
emergency action is taken, the Lead Securitization Note Holder (or the Servicer on its behalf) will promptly notify the Directing
Holder of the action so taken, the Servicer’s reasons for determining that immediate action was necessary and how the action
differs from the proposed actions, if any, that had theretofore been approved by the Directing Holder. The provisions of this
Section 21(d) shall be of no further force and effect from and after the Lead Securitization Date, and the analogous provisions
of the Servicing Agreement shall control.


 


(e)       
The Lead Securitization Note Holder (or the Servicer on its behalf) shall be required to provide copies to each Non-Controlling
Holder of any notice, information and report that is required to be provided to the Directing Holder pursuant to the Servicing
Agreement with respect to any Major Decisions within the same time frame such notice, information and report is required to be
provided to the Directing Holder, and the Special Servicer shall be required to consult with each Non-Controlling Holder on a
strictly non-binding basis, to the extent having received such notices, information and reports, any Non-Controlling

Holder requests
consultation with respect to any such Major Decisions, and consider alternative actions recommended by such Non-Controlling Holder;
provided that after the expiration of a period of ten (10) Business Days from the delivery to any Non-Controlling Holder by the
Lead Securitization Note Holder (or the Servicer on its behalf) of written notice of a proposed action, together with copies of
the notice, information and reports, the Lead Securitization Note Holder (or the Servicer on its behalf) shall no longer be obligated
to consult with such Non-Controlling Holder, whether or not such Non-Controlling 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 deemed to begin anew from the date of such proposal and delivery of all
information relating thereto). Notwithstanding the consultation rights of each Non-Controlling Holder set forth in the immediately
preceding sentence, the Lead Securitization Note Holder (or the Servicer on its behalf) may take any Major Decision before the
expiration of the aforementioned ten (10) Business Day period if the Lead Securitization Note Holder (or the Servicer on its behalf)
determines that immediate action with respect thereto is necessary to protect the Mortgaged Properties or the interests of the
Holders (as a collective whole).


 


In
addition to the consultation rights provided in the immediately preceding paragraph, each Non-Controlling Holder shall have the
right to attend annual meetings (which may be held telephonically or in person, at the discretion of the Servicer) with the Lead
Securitization Noteholder (or the Servicer on its behalf), upon reasonable notice and at times reasonably acceptable to the (or
the Servicer on its behalf) in which servicing issues related to the Mortgage Loan are discussed.


 


(f)       
Notwithstanding anything herein to the contrary, no advice, direction or objection from or by the Directing Holder, as contemplated
by this Section 21, or no advice, direction or objection, if any, from or by any Non-Controlling Holder, may (and
the related Holder (or the Servicer on its behalf) shall ignore and act without regard to any such advice, direction or objection
that such Holder (or Servicer on its behalf) has determined, in its reasonable, good faith judgment, would): (A) require or cause
such Holder (or the Servicer on its behalf) to violate applicable law, the terms of the Mortgage Loan Documents or any section
of this Agreement or any Servicing Agreement, including such Servicer’s obligation to act in accordance with Accepted Servicing
Practices, (B) result in the imposition of federal income tax on any Securitization Trust, cause any REMIC to fail to qualify
as a REMIC, (C) expose any Securitization Trust, any certificateholder of any related Securitization, the Depositor or the depositor
of any Non-Lead Securitization, the Holders, the Servicer, the Trustee or the trustee of any Non-Lead Securitization, the Certificate
Administrator or any certificate administrator of any Non-Lead Securitization, the operating advisor of any Non-Lead Securitization
or their respective Affiliates, members, managers, officers, directors, employees or agents, to any material claim, suit or liability
or (D) materially expand the scope of the Servicer’s responsibilities under this Agreement or the related Servicing Agreement.


 


(g)      
No Controlling Holder or Directing Holder shall owe any fiduciary duty to the trustee, any servicer, any special servicer, any
certificateholder in any Securitization or the other Holders. No Controlling Holder or Directing Holder shall have any liability
to any of the trustee, any servicer, any  special servicer, any certificateholder in any Securitization or the other

Holders for any action taken, or for refraining
from the taking of any action or the giving of any consent. Each Holder (by acceptance of its Note) acknowledges and agrees that
(i) the Controlling Holder and the Directing Holder may each have relationships and interests that conflict with those of
certificateholders in any Securitization and/or the other Holders; (ii) the Controlling Holder and the Directing Holder may
act solely in their respective interests; (iii) the Controlling Holder and the Directing Holder do not have any duties to
any Securitization Trust, the certificateholders in any Securitization or the other Holders; (iv) each of the Controlling
Holder and the Directing Holder may take actions that favor interests of itself over the interests of the certificateholders in
any Securitization and/or the other Holders; (v) neither the Controlling Holder nor the Directing Holder will have any liability
whatsoever to any Securitization Trust, any party to the Lead Securitization Servicing Agreement, any party to any Non-Lead Securitization
Servicing Agreement, the certificateholders in any Securitization or the other Holders or any other person (including the Borrowers)
for having acted in accordance with or as permitted under the terms of the Lead Securitization Servicing Agreement and this paragraph;
and (vi) the certificateholders in any Securitization or the other Holders may not take any action whatsoever against the
Controlling Holder or the Directing Holder or any of the respective affiliates, directors, officers, shareholders, members, partners,
agents or principals thereof as a result of the Controlling Holder or the Directing Holder having acted in accordance with the
terms of and as permitted under the Lead Securitization Servicing Agreement and this paragraph.


 


(h)      
The Controlling 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 replacement Special Servicer in lieu thereof. Any such replacement
Special Servicer shall be a Qualified Servicer in accordance with this Section 21(h). The Controlling Holder shall designate
a Person to serve as Special Servicer by delivering to the Non-Controlling Holders, the Servicer and the then existing Special
Servicer a written notice stating such designation and by satisfying the other conditions required under the Servicing Agreement
(including a Rating Agency Confirmation, if required by the terms of the Servicing Agreement), and by delivering to Holder that
is a Non-Lead Securitization a Rating Agency Confirmation with respect to any rated securities issued in such Non-Lead Securitization.
The Controlling Holder shall promptly pay any expenses incurred by the Lead Securitization Note Holder (or the Servicer on its
behalf) in connection with such replacement. The Controlling Holder shall notify the other parties hereto of its termination of
the then currently serving Special Servicer and its appointment of a replacement Special Servicer in accordance with this Section 21(h).
The fees payable to any replacement Special Servicer contemplated in this Section 21(h) at any time, from and after
the Lead Securitization, when the Lead Securitization Servicing Agreement is no longer in effect, shall be at then market rates
for such services. Upon the occurrence of the Lead Securitization governing the servicing of the Mortgage Loan, the initial Special
Servicer designated in the applicable Lead Securitization Servicing Agreement shall serve as the initial Special Servicer. If
a Special Servicer Termination Event on the part of the Special Servicer has occurred that affects the Non-Controlling Holder,
the Non-Controlling Holder shall have the right to direct the Trustee (or at any time that the Mortgage Loan is no longer included
in a Securitization, the Controlling Holder) to terminate the Special Servicer under the applicable Servicing Agreement solely
with respect to the Mortgage Loan pursuant to


 



    
	63 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


and in accordance with the terms of the Servicing Agreement. The Controlling Holder
and the Non-Controlling Holder acknowledge and agree that any successor special servicer appointed to replace the Special Servicer
with respect to the Mortgage Loan that was terminated for cause at the Non-Controlling Holder’s direction cannot at any
time be the person (or an Affiliate thereof) that was so terminated without the prior written consent of the Non-Controlling Holder.
From and after the Lead Securitization Date, the termination and replacement of the Special Servicer shall be governed by the
Lead Securitization Servicing Agreement.

(j)        
Notwithstanding the foregoing, within ten (10) Business Days after receipt by the Note B-1 Holder, the Note B-2 Holder, the Note
B-3 Holder or the Note B-4 Holder of notice indicating that such Note B Holder is no longer the Controlling Holder, such Note
B Holder may, at its option, post with the Lead Securitization Note Holder (or, if a Securitization has occurred, with the applicable
Master Servicer, Special Servicer, or Trustee) (a) cash collateral for the benefit of, and reasonably acceptable to the Lead
Securitization Note Holder, the Servicer or the Special Servicer, as the case may be, or (b) a Letter of Credit (in each
case, if there has been a Securitization, together with documentation reasonably acceptable to the Lead Securitization Note Holder,
the Servicer or the Special Servicer to create and perfect a first priority security interest in favor of the Securitization in
such collateral) (to be held by Lead Securitization Note Holder in a segregated securities account solely and exclusively in the
name of each Note A Holder, meeting the Rating Agency criteria for an “eligible account” on behalf of each Note A
Holder) in an amount which, when added to and for this purpose considered a part of the appraised value of the Mortgaged Properties,
will cause the related Note B Holder to remain the Controlling Holder (such cash or Letter of Credit, “Reserve Collateral”).
The applicable Note B Holder may make such election upon written notice to the Lead Securitization Note Holder of its intention
to post Reserve Collateral, and upon notifying Lead Securitization Note Holder of such intention, such Note B Holder shall post
such Reserve Collateral as quickly as practicable (but in no event more than three (3) Business Days following the receipt of
the above notice) by delivering such Reserve Collateral to Lead Securitization Note Holder. The applicable Note B Holder shall
grant to and create in favor of each Note A Holder a first priority perfected pledge and security interest in the Reserve Collateral
in a manner reasonably satisfactory to Lead Securitization Note Holder. Lead Securitization Note Holder will require an opinion,
in form and substance and from counsel reasonably acceptable to Lead Securitization Note Holder, regarding the validity, perfection
and priority of each Note A Holder’s interest in any Reserve Collateral. In addition, the applicable Note B Holder shall
pay or cause to be paid any and all reasonable out of pocket costs and expenses incurred by each Note A Holder (and any servicing
party on its behalf) associated with the delivery and/or pledge of such Reserve Collateral, including the costs and expenses of
any opinion of counsel. Upon the posting of such Reserve Collateral and satisfaction of the other conditions set forth above,
the applicable Note B Holder shall be entitled to exercise all of the rights of the Controlling Holder hereunder; provided, however,
that such posting of such collateral and such satisfaction of conditions shall not prevent such Note B Holder from losing its
status as the Controlling Holder again (provided that such collateral shall be taken into account in determining the Mortgaged
Properties’ value when calculating whether such Note B Holder is no longer the Controlling Holder), in which


 



    
	64 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


 event the foregoing
provisions of this paragraph shall not again apply and such Note B Holder shall not again be entitled to post Reserve Collateral.
Any Reserve Collateral shall be treated as an “outside reserve fund” for purposes of the REMIC provisions of the Internal
Revenue Code of 1986, as amended, and such property (and the right to reimbursement of any amounts with respect thereto from a
REMIC) shall be beneficially owned by such Note B Holder, who shall be taxed on all income with respect thereto. The provisions
of this Section 21(j) shall be of no further force and effect from and after the Lead Securitization Date.


 


(k)      
Following a Final Recovery Determination with respect to the Mortgage Loan and application of all proceeds of the liquidation
of the Mortgage Loan, the Mortgaged Properties or any REO Property, the Lead Securitization Note Holder (or the Servicer on its
behalf) shall be entitled to draw on or liquidate the Reserve Collateral and apply the proceeds thereof to reimburse each Note
A Holder for any Trust Fund Expense or Realized Loss borne or experienced by each Note A Holder, plus interest thereon from the
date such Trust Fund Expenses or Realized Loss was borne or experienced to the date of reimbursement. Within ten (10) Business
Days following such Final Recovery Determination and application, the Lead Securitization Note Holder (or the Servicer on its
behalf) shall pay any remaining portion of such proceeds of the Reserve Collateral to the Note B Holder. The provisions of this
Section 21(k) shall be of no further force and effect from and after the Lead Securitization Date.


 


(l)        
Notwithstanding the foregoing, if a Letter of Credit is posted as Reserve Collateral, then the related Note B Holder shall provide
a replacement Letter of Credit from an Approved Bank in form and substance satisfactory to Lead Securitization Note Holder and
each of such Rating Agencies (i) at least fifteen (15) Business Days before the expiration of the delivered Letter of Credit,
and (ii) if the issuer of such Letter of Credit is at any time not an Approved Bank, within five (5) Business Days following written
notice from Lead Securitization Note Holder to such effect. If the related Note B Holder does not effect such a replacement within
the periods set forth in the preceding sentence, the Lead Securitization Note Holder shall be entitled immediately thereupon to
draw on such Letter of Credit to the full extent of the amount then remaining available thereunder, in which case Lead Securitization
Note Holder shall hold the proceeds of such draw as Reserve Collateral and shall be entitled to hold and apply such Reserve Collateral
in the manner and for the purposes otherwise set forth above and below. The provisions of this Section 21(l) shall be of
no further force and effect from and after the Lead Securitization Date.


 


22.      
Further Assurances. Each Holder acknowledges and agrees that each Holder may sell all or any portion of its respective
Note, subject to the rights of the other Holders and the terms of this Agreement, and the related Mortgage Loan Documents in connection
with the related Securitization. At the request and at the sole cost and expense of a requesting Holder, and to the extent not
already required to be provided by the other Holders under this Agreement, each Holder shall reasonably cooperate with such requesting
Holder and take such steps as may be reasonably required by such requesting Holder or any Rating Agency in order to satisfy the
market standards to which the requesting Holder customarily adheres or which may be reasonably required by the Rating Agencies
in connection with the related Securitization. Such cooperation shall include, without limitation, each Holder’s agreement
to:

to a “Controlling Holder” or “Directing Holder”) or increase the obligations of such Holder hereunder;


 


(b)

Servicing Agreement or any other provision of this Agreement or the Servicing Agreement.

Note B Holder shall be entitled to receive its share of such application in accordance with the terms of this Agreement and/or
the Servicing Agreement.

33.       
Statement of Intent. It is the intention of the parties hereto that, for purposes of federal income taxes, state and local
income and franchise taxes and any other taxes imposed upon, measured by or based upon gross or net income, this Agreement shall
be treated as creating a “grantor trust” (within the meaning of Code Section 671). The terms of this Agreement shall
be interpreted to further this intention of the parties. The parties hereto agree that, unless otherwise required by appropriate
tax authorities, the Lead Securitization Note Holder (or the Trustee (if any) or any other party so designated under the Lead
Securitization Agreement on its behalf) shall file or cause to be filed annual or other necessary returns, reports and other forms
consistent with such intended characterization. Each other Holders by its acceptance of its interest herein, agrees, unless otherwise
required by appropriate tax authorities, to file its own tax returns and reports in a manner consistent with such characterization.
If the Internal Revenue Service were to characterize this Agreement as a partnership for federal income tax purposes, then each
such other Holders authorizes and directs the Lead Securitization Note Holder to elect out of partnership accounting pursuant
to Treasury Regulation Section 1.761-2, and agrees to file its own tax returns and reports in a manner consistent therewith.


 


34.       
Powers. Except as expressly provided herein, the grantor trust created pursuant to this Agreement will not engage in any
activity that is inconsistent with the classification of this arrangement as a grantor trust for federal income tax purposes.
Further, this grantor trust shall not (a) acquire any additional assets or (b) modify (or agree to the modification of) or dispose
of its assets other than pursuant to the terms hereof. The grantor trust shall take no action (or fail to take any action) that
will cause it (by the taking or by the failure to take, as the case may be) to be classified as other than a grantor trust for
federal income tax purposes.


 


35.       
Servicers of the Mortgage Loan. KeyBank National Association is hereby appointed by the Holders as the interim servicer
of the Mortgage Loan. From and after the Lead Securitization Date, pursuant to this Agreement and the Lead Securitization Servicing
Agreement, KeyBank National Association will be appointed as the initial master servicer of the Trust Loan and the primary servicer
of the Mortgage Loan and Situs Holdings, LLC will be appointed as the initial special servicer of the Mortgage Loan. Prior to
the Lead Securitization Date, the Lead Securitization Note Holder shall have the right to appoint and remove the Interim Servicer
with or without cause under this Agreement and from and after the Lead Securitization Date, the Lead Securitization Note Holder
shall have the right to appoint and remove the Master Servicer and the Special Servicer in accordance with the terms of the Lead
Securitization Servicing Agreement. All rights and obligations of the Lead Securitization Note Holder described hereunder may
be exercised by the Servicer and/or the Special Servicer (except as set forth in the preceding sentence) and, to the extent applicable,
the Certificate Administrator, the Trustee or the paying agent on behalf of the Lead Securitization Note Holder and the other
Holders agree to cooperate with any such Persons with respect to its exercise of such rights and obligations.


 


36.       
Registration of Transfers. The Lead Securitization Note Holder (or the applicable Servicer or the Trustee on its behalf)
shall maintain a register on which it shall record the names and addresses of, and wire transfer instructions for, the Holders
from time to time, to the extent such information is provided in writing to it by any other Holders. Any transfer of a

Note hereunder
shall be recorded on such register. The transferring Holder (or the transferee) shall reimburse the Lead Securitization Note Holder
for the Lead Securitization Note Holder’s reasonable third party out-of-pocket costs and expenses (including reasonable
attorneys’ fees and disbursements) incurred in connection with the terms of this Section 36.


 


37.      
Non-Recourse Obligations of the Holders. Notwithstanding anything to the contrary contained herein or the Servicing Agreement
(but subject to Section 10 and Section 40 hereof), no Holder shall be personally liable hereunder or under the Servicing
Agreement other than to the extent of cash, property or other value realized or derived from its Note either (i) prior to its
disbursement and receipt by the Holder or (ii) after its receipt by the Holder under the circumstances and to the extent provided
under Section 8(b) hereof.


 


38.      
[Reserved.]


 


39.      
Withholding Taxes.


 


(a)       
If the Lead Securitization Note Holder or the Mortgage Loan Borrowers shall be required by law to deduct and withhold Taxes from
interest, fees or other amounts payable to the other Holders with respect to the Mortgage Loan as a result of such Holder constituting
a Non-Exempt Person, the Servicer shall be entitled to do so with respect to such Holder’s interest in such payment (all
withheld amounts being deemed paid to such Holder), provided that the Servicer shall furnish such Holder with a statement setting
forth the amount of Taxes withheld, the applicable rate and other information which may reasonably be requested for purposes of
assisting such Holder to seek any allowable credits or deductions for the Taxes so withheld in each jurisdiction in which such
Holder is subject to tax.


 


(b)      
Each Holder shall and hereby agrees to indemnify the Lead Securitization Note Holder (or any Servicer on its behalf) against and
hold the Lead Securitization Note Holder (or any Servicer on its behalf) harmless from and against any Taxes, interest, penalties
and attorneys’ fees and disbursements arising or resulting from any failure of the Lead Securitization Note Holder (or any
Servicer on its behalf) to withhold Taxes from payment made to such Holder in reliance upon any representation, certificate, statement,
document or instrument made or provided by such Holder to the Lead Securitization Note Holder in connection with the obligation
of the Lead Securitization Note Holder (or any Servicer on its behalf) to withhold Taxes from payments made to such Holder, it
being expressly understood and agreed that (i) the Lead Securitization Note Holder shall be absolutely and unconditionally entitled
to accept any such representation, certificate, statement, document or instrument as being true and correct in all respects and
to fully rely thereon without any obligation or responsibility to investigate or to make any inquiries with respect to the accuracy,
veracity, correctness or validity of the same and (ii) such Holder shall, upon request of the Lead Securitization Note Holder
and at its sole cost and expense, defend any claim or action relating to the foregoing indemnification using counsel reasonably
satisfactory to the Lead Securitization Note Holder.


 


(c)      
Each Holder represents to the Lead Securitization Note Holder (for the benefit of the Mortgage Loan Borrowers) that it is not
a Non-Exempt Person and that neither the Lead Securitization Note Holder nor the Mortgage Loan Borrowers are obligated under

	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


applicable
law to withhold Taxes on sums paid to it with respect to the Mortgage Loan or otherwise pursuant to this Agreement. Contemporaneously
with the execution of this Agreement and from time to time as necessary during the term of this Agreement, each Holder shall deliver
to the Lead Securitization Note Holder, or the Servicer, as applicable, evidence satisfactory to the Lead Securitization Note
Holder substantiating that it is not a Non-Exempt Person and that the Lead Securitization Note Holder is not obligated under applicable
law to withhold Taxes on sums paid to it with respect to the Mortgage Loan or otherwise under this Agreement. Without limiting
the effect of the foregoing, (a) if a Holder is created or organized under the laws of the United States, any state thereof or
the District of Columbia, it shall satisfy the requirements of the preceding sentence by furnishing to the Lead Securitization
Note Holder an Internal Revenue Service Form W-9 and (b) if a Holder is not created or organized under the laws of the United
States, any state thereof or the District of Columbia, and if the payment of interest or other amounts by the Mortgage Loan Borrowers
is treated for United States income tax purposes as derived in whole or part from sources within the United States, such Holder
shall satisfy the requirements of the preceding sentence by furnishing to the Lead Securitization Note Holder Internal Revenue
Service Form W-8ECI, Form W-8BEN or Form W-8BEN-E, as applicable, or successor forms, as may be required from time to time, duly
executed by such Holder, as evidence of such Holder’s exemption from the withholding of United States tax with respect thereto.
The Lead Securitization Note Holder shall not be obligated to make any payment hereunder to each other Holder in respect of its
Note or otherwise until such Holder shall have furnished to the Lead Securitization Note Holder the requested forms, certificates,
statements or documents.


 


40.      
Cooperation in Securitization; Re-Sizing of A Note; Provisions Relating to Securitization.


 


(a)      
In connection with the Lead Securitization or any Non-Lead Securitization, Note B Holders hereby consent to the inclusion in any
disclosure document relating to the Lead Securitization or such Non-Lead Securitization of the identity of the Note B Holders
and the identification of other Persons that control the related B Note (other than the identification of its limited partners
or other non-controlling investors). Note B Holders covenant and agree that in the event any A Note is to be included as an asset
of the Lead Securitization or any Non-Lead Securitization, Note B Holders shall, at the related Initial Note A Holder’s
sole cost and expense (including, without limitation, attorneys’ fees and disbursements reasonably incurred by Note B Holders)
and request, (i) meet with representatives of the Rating Agencies to discuss the business and operations of Note B Holders, (ii)
cooperate with the reasonable requests of each Rating Agency and such Initial Note A Holder in connection with the Lead Securitization
or such Non-Lead Securitization, as well as in connection with all other matters and the preparation of any offering documents
thereof and (iii) review and respond promptly with respect to any information (except as permitted above) relating to Note B Holders
in the Lead Securitization or such Non-Lead Securitization document.


 


(b)      
Notwithstanding any other provision of this Agreement, for so long as any Initial Holder or any affiliate thereof (an “Initial
Holder Entity”) is the owner of an A Note (each, an “Owned Note”), such Initial Holder Entity shall
have the right, subject to the terms of the


 



    
	71 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


Mortgage Loan Documents, to cause the Mortgage Loan Borrowers to execute amended and
restated notes or additional notes (in either case, “New Notes”) reallocating the principal of an Owned Note
to such New Notes; or severing an Owned Note into one or more further “component” notes in the aggregate principal
amount equal to the then outstanding principal balance of such Owned Note provided that (i) the aggregate principal balance of
all outstanding New Notes following such amendments is no greater than the aggregate principal of such Owned Note prior to such
amendments, (ii) all Notes continue to have the same weighted average interest rate as the Notes prior to such amendments, (iii)
all New 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, (iv) the Initial Holder Entity holding the New Notes shall notify the Lead Securitization
Note Holder, the Master Servicer, the Special Servicer, the Certificate Administrator and the Trustee in writing of such modified
allocations and principal amounts, and (v) the execution of such amendments and New Notes does not violate Accepted Servicing
Practices. If the Lead Securitization Note Holder so requests, the Initial Holder Entity holding the New Notes (and any subsequent
holder of such Notes) shall execute a confirmation of the continuing applicability of this Agreement to the New Notes, as so modified.
In connection with the foregoing (provided the conditions set forth in (i) through (v) above are satisfied, with respect to (i)
through (iv), as certified by the applicable Initial Holder Entity, on which certification the Master Servicer can rely), the
Master Servicer is hereby authorized and directed to execute amendments to the Mortgage Loan Documents and this Agreement on behalf
of any or all of the Holders, as applicable, solely for the purpose of reflecting such reallocation of principal.


 


(c)      
The Lead Securitization Note Holder acknowledges and agrees that it shall cause the Lead Securitization Servicing Agreement to
provide that (and, to the extent such provisions are not included in the Lead Securitization Servicing Agreement they shall be
deemed incorporated therein and made a part thereof):


 


(i)      
the Master Servicer, Special Servicer and Trustee for such Lead Securitization shall be required to notify the master servicer,
the special servicer and the trustee under each Non-Lead Securitization Servicing Agreement of the amount of any P&I Advance
it has made with respect to the Standalone Notes included in the Lead Securitization Trust or Property Advances it has made with
respect to the Mortgaged Properties within two (2) Business Days of making any such advance;


 


(ii)      
if the Master Servicer determines that a proposed P&I Advance or Property Advance, if made, or any outstanding P&I Advance
or Property Advance previously made, would be, or is, as applicable, a “nonrecoverable advance,” the Master Servicer
shall provide the servicers under any Non-Lead Securitization Servicing Agreement written notice of such determination within
two (2) Business Days after such determination was made and such determination with regard to any Property Advance shall be binding
on the servicers under the Non-Lead Securitization Servicing Agreement;


 


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


 



    
	72 
	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


each such Note, and any other applicable fees and reimbursements payable to the Master Servicer, the
Special Servicer and the Trustee, to the Holders of such Notes on or prior to the Remittance Date;


 


(iv)     
with respect to each other Note that is held by a Non-Lead Securitization, the Master Servicer shall make available all reports

(v)      
the Master Servicer and Special Servicer shall provide to each Non-Standalone Note Holder all documents and other information

Agreement at the time provided to such Controlling Class Representative;


 


(vi)     
the servicing duties of each of the Master Servicer and Special Servicer under the Lead Securitization Servicing Agreement shall

and Accepted Servicing Practices;


 


(vii)    
the Holders of the Non-Standalone Notes shall be entitled to the same indemnity by the applicable parties to the Lead Securitization
Servicing Agreement with respect to the Mortgage Loan as the applicable parties to the Lead Securitization Servicing Agreement
are provided with respect to the Mortgage Loan under the Lead Securitization Servicing Agreement; the Master Servicer, any primary
servicer, the Special Servicer, the trustee and the certificate administrator shall be required to indemnify each “certification
party” and the depositors under each Non-Lead Securitization Servicing Agreement related to any public Non-Lead Securitization
to the same extent that they indemnify the Lead Securitization “certification party” and depositor for their failure
to deliver the items in clause (viii) below in a timely manner and for any Deficient Exchange Act Deliverable (as defined in the
Lead Securitization Servicing Agreement or any similar term thereto) regarding, and delivered by or on behalf of, such party;


 


(viii)   
with respect to any Non-Lead Securitization that is subject to following reporting requirements under the Securities Act of 1933,
as amended, the Securities Exchange Act of 1934 (including Rule 15Ga-1), as amended, and Regulation AB, (a) the Master Servicer,

	Co-Lender Agreement
	(Cambridge Crossing – 350 and 450 Water Street)




     


    

 


(i) the reports, certifications, compliance statements, accountants’ assessments
and attestations, information to be included in reports (including, without limitation, Form 15G, Form 10-K, Form 10-D and Form
8-K), and (ii) upon request, any other materials specified in each of the Non-Lead Securitization Servicing Agreements as the
parties to the applicable Non-Lead Securitization may require in order to comply with their obligations under the Securities Act
of 1933, as amended, Securities Exchange Act of 1934 (including Rule 15Ga-1), as amended, and Regulation AB, and any other applicable
law, and (2) to the extent applicable, to cooperate with any depositor in a Non-Lead Securitization in responding to comments

the generality of the foregoing, the Depositor for the Lead Securitization shall provide in a timely manner to the depositor and
the trustee for any Non-Lead Securitization a copy of the Lead Securitization Servicing Agreement and each of the Master Servicer,
the Special Servicer, Trustee, certificate administrator or other party acting as custodian for the Lead Securitization will be

Securitization Servicing Agreement;

each of the Master Servicer, the Special Servicer, the custodian, the Trustee and the certificate administrator and each Affected

Servicing Agreement) retained by it to cooperate under any applicable sub-servicing agreement), with each depositor for a Non-Lead
Securitization (including, without limitation, providing all due diligence information, reports, written responses, negotiations
and coordination, and paying all costs and expenses incurred in connection therewith) to the same extent as such party is required
to cooperate with (and pay the expenses of) the Depositor under the Lead Securitization Servicing Agreement in connection with
Deficient Exchange Act Deliverables (as defined in the Lead Securitization Servicing Agreement);


 


(x)      
amounts received by the Master Servicer that represent late collections or principal prepayments on the Non-Standalone Notes,
net of any portion thereof payable or reimbursable to any third party in accordance with this Agreement, shall be remitted by
the Master Servicer to the Holders of such Non-Standalone Notes within one (1) Business Day of receipt of properly identified
funds; provided, however, to the extent any such amounts are received after 3:00 p.m. Eastern time on any given

funds;


 


(xi)     
each Holder of a Non-Standalone Note is an intended third-party beneficiary in respect of the rights afforded them under the Lead

Securitization Servicing Agreement) reports required under the Securities Exchange

trustee of the Lead Securitization and each other Non-Lead Securitization of any monthly
principal and interest advance it has made with respect to the applicable Note included in such Non-Lead Securitization within
two Business Days of making such advance;


 


(ii)      
if the applicable master servicer, special servicer or trustee determines that a proposed monthly principal and interest advance
with respect to the related Note, if made, or any outstanding monthly principal and interest advance previously made, would be,
or is, as applicable, a “nonrecoverable advance,” the master servicer shall provide the Master Servicer and each master
servicer in any other Non-Lead Securitization written notice of such determination within 2 Business Days after such determination
was made;


 


(iii)      
if the related Holder of such Note is responsible for its proportionate share of any Nonrecoverable Property Advances (or any
other portion of a Nonrecoverable Property Advance) (and Advance Interest Amount thereon) or other fee or expense pursuant to

any other costs, liabilities, fees and expenses, incurred in connection with any Non-Lead Securitization Servicing Agreement and
relating to the applicable Note included in such Non-Lead Securitization and (b) the Special Servicer will be a third party beneficiary
under the related Non-Lead Securitization Servicing Agreement with respect to any

provisions therein relating to (1) the reimbursement
of any Nonrecoverable Property Advances made with respect to such Note included in such Non-Lead Securitization by the Special
Servicer (it being understood that the Special Servicer is not required to make any Property Advances) and (2) the indemnification

any other costs, liabilities, fees and expenses, incurred in connection with any Non-Lead Securitization Servicing Agreement and
relating to the applicable Note included in such Non-Lead Securitization; and


 


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

Agreement related to the Non-Lead Securitization that will include such Holder’s Non-Standalone Note) notice of the related
Non-Lead Securitization in writing (which may be by e-mail) not less than 5 Business Days’ prior to the closing of such
Non-Lead Securitization. Such notice shall contain contact information for each of the parties to the applicable Non-Lead Securitization
Servicing Agreement. In addition, after the closing of the applicable Non-Lead Securitization, such Non-Standalone Note Holder
shall send (i) a copy of the related Non-Lead Securitization Servicing Agreement to each of the parties to the Lead Securitization
Servicing Agreement and (ii) notice of any subsequent change in the identity of the master servicer under the Non-Lead Securitization
Servicing Agreement or the party designated to exercise the rights of the Non-Controlling Holder under this Agreement (together
with the relevant contact information).


 


(f)       
Following the closing of the Lead Securitization, upon receipt of written notice (which may be by email) of the closing of any
Non-Lead Securitization, the Depositor shall provide the depositor under the related Non-Lead Securitization Servicing Agreement
