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 Deutsche Bank Trust Company Americas, as Trustee, Certificate Administrator and Custodian.

Deutsche Bank Trust Company Americas (“DBTCA”) and Deutsche
Bank National Trust Company (“DBNTC”) have been sued by investors in civil litigation concerning their roles as trustees
of certain residential mortgage-backed securities (“RMBS”) trusts.

On June 18, 2014, a group of investors, including funds managed by Blackrock
Advisors, LLC, PIMCO-Advisors, L.P., and others, filed an action against DBNTC and DBTCA in New York State Supreme Court alleging that
DBNTC and DBTCA failed to perform purported duties, as trustees for 544 private-label RMBS trusts, to enforce breaches of representations
and warranties as to mortgage loans held by the trusts and to enforce breaches by servicers of their mortgage loan servicing obligations
for the trusts. During the course of the litigation, plaintiffs dismissed the case from New York State Supreme Court and refiled two separate
cases, one in the U.S. District Court for the Southern District of New York (the “BlackRock SDNY Case”) and the other
in the Superior Court of California, Orange County (the “BlackRock California Case”). Pursuant to a settlement among
the parties, the BlackRock SDNY Case was dismissed on December 6, 2018, and the BlackRock California Case was dismissed on January 11,
2019.

On September 27, 2017, DBTCA was added as a defendant to a case brought by
certain special purpose entities including Phoenix Light SF Limited in the U.S. District Court for the Southern District of New York,
in which the plaintiffs previously alleged incorrectly that DBNTC served as trustee for all forty-three of the trusts at issue. On September
27, 2017, plaintiffs filed a third amended complaint that names DBTCA as a defendant in addition to DBNTC. DBTCA serves as trustee for
one of the forty-three trusts at issue. DBNTC serves as trustee for the other forty-two trusts at issue. Plaintiffs’ third amended
complaint brings claims for violation of the U.S. Trust Indenture Act of 1939 (“TIA”); breach of contract; breach of
fiduciary duty; negligence and gross negligence; violation of New York’s Streit Act; and breach of the covenant of good faith. However,
in the third amended complaint, plaintiffs acknowledge that, before DBTCA was added to the case, the court dismissed plaintiffs’
TIA Act claims, negligence and gross negligence claims, Streit Act claims, claims for breach of the covenant of good faith, and certain
theories of plaintiffs’ breach of contract claims, and plaintiffs only include these claims to preserve any rights on appeal. Plaintiffs
allege damages of “hundreds of millions of dollars.” On November 13, 2017, DBNTC and DBTCA filed an answer to the third amended
complaint. On December 7, 2018, DBNTC and DBTCA filed a motion for summary judgment. Also on December 7, 2018, plaintiffs, jointly with
Commerzbank AG (see description of Commerzbank case below), filed a motion for partial summary judgment. On October 27, 2021, DBNTC and
DBTCA filed a supplemental motion for summary judgment relating to plaintiffs’ standing. On February 8, 2022, the court issued an
order in which it granted DBNTC and DBTCA’s supplemental motion for summary judgment, granted in part DBNTC and DBTCA’s initial
motion for summary judgment, and denied plaintiffs’ motion for partial summary judgment. As a result of that order, all of plaintiffs’
claims were dismissed with prejudice.

On November 30, 2017, DBTCA was added as a defendant to a case brought by
Commerzbank AG (“Commerzbank”) in the U.S. District Court for the Southern District of New York, in which Commerzbank
previously alleged incorrectly that DBNTC served as trustee for all fifty of the trusts at issue. On November 30, 2017, Commerzbank filed
a second amended complaint that names DBTCA as a defendant in addition to DBNTC. DBTCA serves as trustee for one of the fifty trusts at
issue. DBNTC serves as trustee for the other forty-nine trusts at issue. Commerzbank’s second amended complaint brings claims for
violation of the TIA; breach of contract; breach of fiduciary duty; negligence; violation of the Streit Act; and breach of the covenant
of good faith. However, in the second amended complaint, Commerzbank acknowledges that, before DBTCA was added to the case, the court
dismissed Commerzbank’s TIA claims for the trusts governed by pooling and servicing agreements, as well as its Streit Act claims
and claims for breach of the covenant of good faith, and Commerzbank only includes these claims to preserve any rights on appeal. The
second amended complaint alleges that DBNTC and DBTCA caused Commerzbank to suffer “hundreds of millions of dollars in losses,”
but the complaint does not include a demand for money damages in a sum certain. On January 29, 2018, DBNTC and DBTCA filed an answer to
the second amended complaint. On December 7, 2018, DBNTC and DBTCA filed a motion for summary judgment. Also on December 7, 2018, Commerzbank,
jointly with the Phoenix Light plaintiffs, filed a motion for partial summary judgment. On February 8, 2022, the court issued an order
in which it granted in part DBNTC and DBTCA’s motion for summary judgment and denied plaintiffs’ motion for partial summary
judgment. As a result of that order, many of plaintiffs’ claims and theories were dismissed with prejudice. Discovery is ongoing.

On December 30, 2015, IKB International, S.A. in Liquidation and IKB Deutsche
Industriebank A.G. (collectively, “IKB”), as an investor in thirty-seven RMBS trusts, filed a summons with notice in
the Supreme Court of the State of New York, New York County, against DBNTC and DBTCA as trustees of the trusts. On May 27, 2016, IKB served
its complaint asserting claims for breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts of interest, violation
of the Streit Act, violation of the TIA, violation of Regulation AB, and violation of Section 9 of the Uniform Commercial Code. IKB alleges
that DBNTC and DBTCA are liable for over U.S. $268 million in damages. On October 5, 2016, DBNTC and DBTCA, together with several other
trustees defending lawsuits by IKB, filed a joint motion to dismiss. On January 6, 2017 and June 20, 2017, IKB voluntarily dismissed with
prejudice all claims as to seven trusts. On January 27, 2021, the court granted in part and denied in part DBNTC and DBTCA’s motion
to dismiss. The court granted the motion to dismiss with respect to IKB’s claims for violations of the Streit Act, Regulation AB,
and Section 9 of the Uniform Commercial Code, as well as certain aspects of IKB’s claims for breach of contract, breach of fiduciary
duty, and violation of the TIA. The court denied the remainder of the motion to dismiss. IKB’s remaining claims for breach of contract,
breach of fiduciary duty, breach of duty to avoid conflicts of interest, and violation of the TIA will proceed. On May 10, 2021, DBNTC
and DBTCA filed a notice of appeal with the New York Supreme Court Appellate Division, First Department, regarding certain aspects of
the court’s order on the motion to dismiss. That appeal has been fully briefed. On May 20, 2021, IKB filed a notice of cross appeal
with respect to other aspects of that order. That appeal is being briefed. On June 2, 2021, IKB filed a motion for re-argument regarding
certain aspects of the court’s order on the motion to dismiss, which the court denied on August 3, 2021. On May 13, 2021, DBNTC
and DBTCA filed an answer to the complaint. On October 28, 2021, the parties filed a stipulation, voluntarily dismissing with prejudice
all claims as to seven additional trusts. On December 29, 2021, the parties filed a stipulation, voluntarily dismissing with prejudice
all claims as to one additional trust. Discovery is ongoing.

It is DBTCA’s belief that it has no pending legal proceedings (including,
based on DBTCA’s present evaluation, the litigation disclosed in the foregoing paragraphs) that would materially affect its ability
to perform its duties under the related servicing agreement for this transaction.

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 September 26, 2012 pursuant to Rule 424(b)(5).

asset-backed securities and related attestation reports on such assessments of compliance with respect to the mortgage loans are attached

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).
