Part II - OTHER INFORMATION

Item 2. Legal Proceedings.
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 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; 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.  As of March 8, 2019, both motions 
for summary judgment have been briefed and are awaiting decision by the court.  Discovery is 
ongoing.

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.  As of 
March 8, 2019, both motions for summary judgment have been briefed and are awaiting decision 
by the court.  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 June 2, 2021, IKB filed a motion for re-argument regarding certain 
aspects of that order.  On May 13, 2021, DBNTC and DBTCA filed an answer to the complaint.  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 as Trustee under the Pooling and Servicing Agreement, for this transaction.

Item 6.  Significant Obligors of Pool Assets.
The 260 and 261 Madison Avenue mortgaged property constitutes a
significant obligor within the meaning of Item 1101(k)(2) of
Regulation AB. Based on the information provided by the 260 and
261 Madison Avenue mortgage loan borrower, the unaudited net
operating income of the significant obligor was $5,246,477.00,
a year-to-date figure for the period of January 1, 2021
through March 31, 2021.
