RECITALS


A.       On
or prior to the Closing Date, a legal fee reserve account was established in connection with the BANK 2017-BNK4 transaction and,
on the Closing Date, the Depositor deposited $250,000 with the Certificate Administrator, to be credited to the legal fee reserve
account.


B.       The
Depositor desires to amend the Agreement to provide for the legal fee reserve account described above.


C.       Section
13.01(a) of the Agreement provides that the Agreement may be amended from time to time by the agreement of the Depositor, the
Master Servicer, the Special Servicer, the Certificate Administrator, the Trustee, the Operating Advisor and the Asset Representations
Reviewer, without the consent of any of the Certificateholders or the Companion Holders, among other things, to revise or add
any other provisions with respect to matters or questions arising under the Agreement or any other change; provided that
the required action shall not adversely affect in any material respect the interests of any Certificateholder (including, for
the avoidance of doubt, any Holder of an RR Interest) or any holder of a Serviced Pari Passu Companion Loan not consenting to
such revision or addition, as evidenced in writing by an Opinion of Counsel, at the expense of the party requesting such amendment
or as evidenced by a Rating Agency Confirmation from each of the Rating Agencies with respect to such amendment or supplement
and confirmation of the applicable rating agencies that such action will not result in the downgrade, withdrawal or qualification
of its then-current ratings of any Serviced Companion Loan Securities, if any (provided that such rating agency confirmation may
be considered satisfied in the same manner as any Rating Agency Confirmation may be considered satisfied with respect to the Certificates
pursuant to Section 3.25 of the Agreement); provided, further, no such amendment (A) may change in any manner any
defined term used in any Mortgage Loan Purchase Agreement or the obligations or rights of any Mortgage Loan Seller under any Mortgage
Loan Purchase Agreement or otherwise or change any rights of any Mortgage Loan Seller as a third party beneficiary under the Agreement,
without the consent of such Mortgage Loan Seller or (B) may materially and adversely affect the holder of a Companion Loan without
such Companion Holder’s consent.

D.       Section
13.01(c) of the Agreement provides that (x) none of the Operating Advisor, the Asset Representations Reviewer, the Trustee, the
Certificate Administrator, the Depositor, the Master Servicer or the Special Servicer shall consent to any amendment to the Agreement
unless it shall first have received an Opinion of Counsel to the effect that such amendment is permitted under the Agreement and
that such amendment or the exercise of any power granted to the Master Servicer, the Special Servicer, the Depositor, the Trustee,
the Certificate Administrator, the Operating Advisor, the Asset Representations Reviewer or any other specified person in accordance
with such amendment will not result in the imposition of a tax on any portion of the Trust Fund or any Trust REMIC, or cause any
Trust REMIC to fail to qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor trust under the relevant
provisions of the Code, and (y) no amendment to the Agreement may be made that changes any provision specifically required to
be included in the Agreement by an Intercreditor Agreement related to a Companion Loan without, in each case, the consent of the
holder of the related Companion Loan(s).


E.       The
Opinion of Counsel required by the Agreement has been delivered to the Operating Advisor, the Asset Representations Reviewer,
the Trustee, the Certificate Administrator, the Depositor, the Master Servicer and the Special Servicer.
