Disclosure from Deutsche Bank Trust Company Americas, as trustee, as certificate administrator and as custodian:

Deutsche Bank Trust Company Americas (“DBTCA”)
and Deutsche Bank National Trust Company (“DBNTC”) have been sued by investors in civil litigation concerning their
role 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 “BlackRockSDNY Case”) and the other
in the Superior Court of California, Orange County (the “BlackRockCalifornia Case”). Pursuant to a settlement among
the parties, the BlackRockSDNY Case was dismissed on December 6, 2018, and the BlackRockCalifornia 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 43 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 43 trusts at issue. DBNTC serves as trustee for the other 42 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 50 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 1 of the 50 trusts at issue. DBNTC serves
as trustee for the other 49 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
Lightplaintiffs, 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 37 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.
