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 RAIT Partnership, L.P., as loan seller and Deutsche Bank Trust Company Americas, as trustee,
as certificate administrator and as custodian:

On September 20, 2017, RAIT Preferred Funding II, Ltd., or RAIT II,
filed an amended complaint against CWCapital Asset Management, LLC, or CWCapital, Wells Fargo Bank N.A., or Wells Fargo, and U.S.
Bank N.A., or U.S. Bank. This action concerns a loan, or the mortgage loan, to a non-party borrower, or the borrower, in 2007.
RAIT II purchased $18,500,000 of the mortgage loan for which it held a promissory note, or note B. U.S. Bank is the trustee for
a securitization trust that purchased the remaining $190,000,000 of the mortgage loan and for which it held a promissory note,
or note A. CWCapital is the special servicer and Wells Fargo is the master servicer for the mortgage loan (including note A and
note B). The parties’ rights and obligations are governed by, among other things, a pooling and servicing agreement and a
co-lender agreement. The mortgage loan was repaid in May of 2017, and the defendants have alleged that RAIT II was not entitled
to receive any payoff of principal under note B pursuant to the subordination and other provisions of the co-lender agreement.
In the amended complaint, RAIT II alleges, among other things, that the defendants breached certain of its obligations under the
operative documents and RAIT II should have received, among other things, all of its $18.5 million principal under note B. The
court denied defendants’ motion to dismiss RAIT II’s amended complaint, and the parties are now in the midst of the
discovery phase of the litigation. RAIT Partnership, L.P. served as the collateral manager and servicer for RAIT II.

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 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 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 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. As of March 1, 2019, DBNTC and DBTCA’s
motion to dismiss has been briefed and is awaiting decision by the court.

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).

Item 1122 of Regulation AB, Compliance with Applicable Servicing
Criteria.

The reports on assessments of compliance with the servicing criteria
for asset-backed securities and related attestation reports on such assessments of compliance with respect to the mortgage loans
are attached hereto under Item 15 to this Annual Report on Form 10-K. Attached as Schedule II to the Pooling and Servicing Agreement
incorporated by 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).

The report on assessment of compliance with applicable servicing criteria
furnished pursuant to Item 1122 of Regulation AB by Midland Loan Services, a Division of PNC Bank National Association discloses
that a material instance of noncompliance occurred, as described below:

Material Instance of Noncompliance

In certain instances, the Schedule AL Files (Item 1125 of Regulation
AB) were not reported in accordance with the terms specified in the transaction agreements, in conflict with Item 1122(d)(3)(i):
“Reports to investors, including those to be filed with the Commission, are maintained in accordance with the transaction
agreements and applicable Commission requirements. Specifically, such reports: (A) Are prepared in accordance with timeframes and
other terms set forth in the transaction agreements”. The noncompliance consisted of omitted or inaccurately reported numbers
due to the following: (1) the initial setup files contained information at the asset level, and Midland was required to manually
compile the information to present it at the loan level as required by Schedule AL; and (2) certain reporting requirements required
manual processing by Midland, including the use of various data computation formulas, quality control checks and analysis.

The identified instances did not involve the servicing of assets
included in this securitization.

Steps Taken to Remedy the Material Instance of Noncompliance

Midland is currently remediating the Schedule AL reporting for
the CMBS transactions found to be incorrect, and will be making improvements to its systems, processes and procedures to support
its Schedule AL reporting obligations.

Item 1123 of Regulation AB, Servicer Compliance Statement.

The servicer compliance statements are attached as Exhibits to this
Annual Report on Form 10-K.
