     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 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
reports from CoreLogic Solutions, LLC.  This entity was engaged by 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, this
vendor is a “servicer” for the purposes of Item 1122 of Regulation AB.  See Compliance and Disclosure

DISCLOSURE ITEMS FOR REGULATION AB  Item
1112(b) of Regulation AB, Significant Obligor Financial Information.  The
11 West 42nd Street Mortgage Loan (Control Number 1 on Annex A of the prospectus supplement of the registrant relating to the
issuing entity filed on July 31, 2013 pursuant to Rule 424(b)(5)) constitutes a significant obligor within the meaning of Item
1101(k)(2) of Regulation AB as disclosed in the prospectus supplement. In accordance with Item 1112(b) of Regulation AB, the most
recent unaudited net operating income of the significant obligor was $29,270,983.46 for the twelve- month period ended December 31,
2022.  The
Mall St. Matthews Mortgage Loan (Control Number 2 on Annex A of the prospectus supplement of the registrant relating to the issuing
entity filed on July 31, 2013 pursuant to Rule 424(b)(5)) constitutes a significant obligor within the meaning of Item 1101(k)(2)
of Regulation AB as disclosed in the prospectus supplement. In accordance with Item 1112(b) of Regulation AB, the most recent
unaudited net operating income of the significant obligor was $15,391,530.63 for the twelve- month period ended December 31, 2022.    Item
1114(b)(2) of Regulation AB, Significant Enhancement Provider Financial Information.  No
entity or group of affiliated entities provides any external credit enhancement or other support for the certificates within this
transaction as described under Item 1114(a) of Regulation AB.  Item
1115(b) of Regulation AB, Certain Derivatives Instruments (Financial Information).  No
entity or group of affiliated entities provides any derivative instruments or other support for the certificates within this transaction
as described under Item 1115 of Regulation AB.  Item
1117 of Regulation AB, Legal Proceedings.  The
registrant knows of no material pending legal proceeding involving the trust or any party related to the trust, other than routine
litigation incidental to the duties of those respective parties, and the following, with respect to U.S. Bank National Association,
as Trustee, Certificate Administrator and Custodian.  In
the last several years, U.S. Bank National Association (“U.S. Bank”) and other large financial institutions have been
sued in their capacity as trustee or successor trustee for certain residential mortgage backed securities (“RMBS”) trusts.
The complaints, primarily filed by investors or investor groups against U.S. Bank and similar institutions, allege the trustees
caused losses to investors as a result of alleged failures by the sponsors, mortgage loan sellers and servicers to comply with
the governing agreements for these RMBS trusts. Plaintiffs generally assert causes of action based upon the trustees’ purported
failures to enforce repurchase obligations of mortgage loan sellers for alleged breaches of representations and warranties, notify
securityholders of purported events of default allegedly caused by breaches of servicing standards by mortgage loan servicers
and abide by a heightened standard of care following alleged events of default.  U.S.
Bank denies liability and believes that it has performed its obligations under the RMBS trusts in good faith, that its actions
were not the cause of losses to investors, that it has meritorious defenses, and it has contested and intends to continue contesting
the plaintiffs’ claims vigorously. However, U.S. Bank cannot assure you as to the outcome of any of the litigation, or the
possible impact of these litigations on the trustee or the RMBS trusts.  On
March 9, 2018, a law firm purporting to represent fifteen Delaware statutory trusts (the “DSTs”) that issued securities
backed by student loans (the “Student Loans”) filed a lawsuit in the Delaware Court of Chancery against U.S. Bank
National Association (“U.S. Bank”) in its capacities as indenture trustee and successor special servicer, and three
other institutions in their respective transaction capacities, with respect to the DSTs and the Student Loans. This lawsuit is
captioned The National Collegiate Student Loan Master Trust I, et al. v. U.S. Bank National Association, et al., C.A. No. 2018-0167-JRS
(Del. Ch.) (the “NCMSLT Action”). The complaint, as amended on June 15, 2018, alleged that the DSTs have been harmed
as a result of purported misconduct or omissions by the defendants concerning administration of the trusts and special servicing
of the Student Loans. Since the filing of the NCMSLT Action, certain Student Loan borrowers have made assertions against U.S.
Bank concerning special servicing that appear to be based on certain allegations made on behalf of the DSTs in the NCMSLT Action.  U.S.
Bank believes that it has performed its obligations as indenture trustee and special servicer in good faith and in compliance
in all material respects with the terms of the agreements governing the DSTs (the “Governing Agreements”), and accordingly
that the claims against it in the NCMSLT Action are without merit.  U.S.
Bank has filed a motion seeking dismissal of the operative complaint in its entirety with prejudice pursuant to Chancery Court
Rules 12(b)(1) and 12(b)(6) or, in the alternative, a stay of the case while other prior filed disputes involving the DSTs and
the Student Loans are litigated. On November 7, 2018, the Court ruled that the case should be stayed in its entirety pending resolution
of the first-filed cases. On January 21, 2020, the Court entered an order consolidating for pretrial purposes the NCMSLT Action
and three other lawsuits pending in the Delaware Court of Chancery concerning the DSTs and the Student Loans (the “Consolidated
Action”). U.S. Bank and other parties to the Consolidated Action have briefed and argued motions for judgment on the pleadings
pursuant to Chancery Court Rule 12(c) regarding disputed issues of contractual interpretation at issue in one or more of the cases
comprising the Consolidated Action, including the NCMSLT Action. The Court has not yet ruled on these motions or on U.S. Bank’s
dismissal motion in the NCMSLT Action.  Item
1119 of Regulation AB, Affiliations and Certain Relationships and Related Transactions.  The
information regarding this Item has been previously provided in a prospectus supplement of the Registrant relating to the issuing
entity filed on July 31, 2013 pursuant to Rule 424(b)(5).  Item
1122 of Regulation AB, Compliance with Applicable Servicing Criteria.  The
reports on assessments of compliance with the servicing criteria for asset-backed securities and related attestation reports on such
assessments of compliance with respect to the mortgage loans are attached hereto under Item 15 to this Annual Report on Form 10-K. Attached
as Exhibit O to the Pooling and Servicing Agreement incorporated by reference as Exhibit 4 to this Annual Report on Form 10-K is a chart
identifying the entities participating in a servicing function for the transaction responsible for each applicable servicing criteria
set forth in Item 1122(d).   Item
