None.



SUBSTITUTE
INFORMATION INCLUDED IN ACCORDANCE WITH GENERAL INSTRUCTION J TO FORM 10-K:



ITEM
1112(b) OF REGULATION AB. SIGNIFICANT OBLIGORS OF POOL ASSETS (FINANCIAL INFORMATION)



There
is no single obligor that represents more than 10% of the pool assets.



ITEM
1114(b)(2) OF REGULATION AB. CREDIT ENHANCEMENT AND OTHER SUPPORT, EXCEPT FOR CERTAIN DERIVATIVE INSTRUMENTS (FINANCIAL INFORMATION)



There
is no external credit enhancement or other support provider that is liable to provide payments supporting any notes or certificates issued
by the Issuing Entity.



ITEM
1115(b) OF REGULATION AB. CERTAIN DERIVATIVE INSTRUMENTS (FINANCIAL INFORMATION)



No
entity provides any derivative instruments that are used to alter the payment characteristics of the cash flows from the Issuing Entity.



ITEM
1117 OF REGULATION AB. LEGAL PROCEEDINGS



The
Sponsor and the Servicer



The
sponsor is subject to various pending and potential legal and regulatory proceedings in the ordinary course of business, including litigation,
arbitration, claims, investigations, examinations, subpoenas and enforcement proceedings. Some litigation against the sponsor could take
the form of class actions. The outcomes of these proceedings are inherently uncertain, and thus the sponsor cannot confidently predict
how or when these proceedings will be resolved. An adverse outcome in one or more of these proceedings could result in substantial damages,
settlements, fines, penalties, diminished income or reputational harm to the sponsor, and could materially and adversely affect the interest
of the noteholders or the servicer’s ability to perform its duties under the transaction documents.



The
Trustee and the Trust Collateral Agent



In
the ordinary course of business, The Bank of New York Mellon is named as a defendant in legal actions. In connection with its role as
trustee of certain residential mortgage-backed securitization, or RMBS, transactions, The Bank of New York Mellon has been named as a
defendant in a number of legal actions brought by RMBS investors. These lawsuits allege that the trustee had expansive duties under the
governing agreements, including the duty to investigate and pursue breach of representation and warranty claims against other parties
to the RMBS transactions. While it is inherently difficult to predict the eventual outcomes of pending actions, The Bank of New York
Mellon denies liability and intends to defend the litigations vigorously.

1119 OF REGULATION AB. AFFILIATIONS AND CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
