EXPLANATORY
NOTES



The
11 West 42nd Street Mortgage Loan and the Mall St. Matthews Mortgage Loan, which constituted approximately 11.2% and 11.0%, respectively,
of the asset pool of the issuing entity as of its cut-off date, are each an asset of the issuing entity and are each part of a
loan combination that includes the 11 West 42nd Street Mortgage Loan or the Mall St. Matthews Mortgage Loan which are assets of
the issuing entity and one other pari passu loan, which is not an asset of the issuing entity. These loan combinations,
including the 11 West 42nd Street Mortgage Loan and the Mall St. Matthews Mortgage Loan, are being serviced and administered pursuant
to the Pooling and Servicing Agreement, which is incorporated by reference as Exhibit 4 to this Annual Report on Form 10-K.



This
Annual Report on Form 10-K includes assessments of compliance with applicable servicing criteria and accountants’ attestation

the master servicer under the Pooling and Servicing Agreement to remit tax payments received from the escrow accounts of borrowers
to local taxing authorities, to report tax amounts due, to verify tax parcel information, and to verify non-escrow tax payments.
These servicing functions are included within the servicing criteria set forth in Items 1122(d)(4)(xi) and 1122(d)(4)(xii) of
Regulation AB.  Therefore, under the principles-based definition of “servicer” set forth in Item 1101(j) of Regulation
AB that looks to the functions that an entity performs, these vendors are “servicers” for the purposes of Item 1122
of Regulation AB.  See Compliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).
