Part II - OTHER INFORMATION

Item 2. Legal Proceedings.

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 "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 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 the New York Streit Act ("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 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 March 10, 2022, plaintiffs filed a notice of appeal to the United
States Court of Appeals for the Second Circuit with respect to the court's orders on the motions to
dismiss and for summary judgment.

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 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 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, IKB filed a notice of discontinuance, voluntarily
dismissing with prejudice all claims as to three trusts. On June 20, 2017, the parties
filed a stipulation, voluntarily dismissing with prejudice all claims as to four
additional 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.  On May 20, 2021, IKB filed a
notice of cross appeal with respect to other aspects of that order. On August 30, 2022,
the New York Supreme Court, Appellate Division, First Department affirmed in part and
reversed in part the court's order on the motion to dismiss. On September 30, 2022, IKB
filed a motion for reargument or for leave to appeal to the Court of Appeals as to
certain aspects of the First Department's decision.  On September 30, 2022, DBNTC and
DBTCA filed a motion for leave to appeal to the Court of Appeals as to other aspects
of that decision.   On November 10, 2022, the First Department granted DBNTC and DBTCA's
motion for leave to appeal to the Court of Appeals, denied IKB's motion for reargument,
and denied as moot IKB's motion for leave to appeal to the Court of Appeals.   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.  
On April 22, 2022, the parties filed a stipulation, voluntarily dismissing with
prejudice all claims as to 17 certificates at issue (including all claims as to 5 trusts),
leaving 17 trusts at issue. 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 Pooling and Servicing Agreement for this
transaction.
