Item 1117 of Regulation AB Disclosure from Citibank, N.A., as Certificate Administrator: Citibank, N.A. (Citibank) is acting as the Certificate Administrator of this commercial mortgage-backed securities (CMBS) transaction.
In the ordinary course of business, Citibank is involved in a number of legal proceedings, including in connection with its role as trustee of certain residential mortgage-backed securities (RMBS) transactions. Certain of these Citibank
as trustee-related matters are disclosed herein. On June 18, 2014, a civil action was filed against Citibank in the Supreme Court of the State of
New York by a group of investors in 48 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee, asserting claims for purported violations of the Trust Indenture Act of 1939 (the Trust Indenture Act), breach
of contract, breach of fiduciary duty and negligence based on Citibanks alleged failure to perform its duties as trustee for the 48 RMBS trusts. On November 24, 2014, plaintiffs sought leave to withdraw this action. On the same day, a
smaller subset of similar plaintiff investors in 27 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee, filed a new civil action against Citibank in the United States District Court for the Southern District of New
York asserting similar claims as the prior action filed in state court. In January 2015, the court closed plaintiffs original state court action. On September 8, 2015, the federal court dismissed all claims as to 24 of the 27 trusts
and allowed certain of the claims to proceed as to the other three trusts. Subsequently, plaintiffs voluntarily dismissed all claims with respect to two of the three trusts. On April 7, 2017, Citibank filed a motion for summary judgment.
Plaintiffs filed its consolidated opposition brief and cross motion for partial summary judgment on May 22, 2017. Briefing on those motions was completed on August 4, 2017. On March 22, 2018, the court granted Citibanks motion
for summary judgment in its entirety, denied Plaintiffs motion for summary judgment and ordered the clerk to close the case. On April 20, 2018, plaintiffs filed a notice of appeal. Plaintiffs opening brief was filed on
August 3, 2018. Citibank filed its opposition on November 2, 2018. Plaintiffs filed their reply on November 16, 2018. On
November 24, 2015, the same investors that brought the federal case brought a new civil action in the Supreme Court of the State of New York related to 25 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee.
This case includes the 24 trusts previously dismissed in the federal action, and one additional trust. The investors assert claims for breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts of interest, and violation of New
Yorks Streit Act (the Streit Act). Following oral argument on Citibanks motion to dismiss, plaintiffs filed an amended complaint on August 5, 2016. On June 27, 2017, the state court issued a decision, dismissing the
event of default claims, mortgage-file-related claims, the fiduciary duty claims, and the conflict of interest claims. The decision sustained certain breach of contract claims including the claim alleging discovery of breaches of representations and
warranties, a claim related to robo-signing, and the implied covenant of good faith claim. Citibank appealed the lower courts decision, and on January 16, 2018, the Appellate Division, First Department, dismissed the claims related to
robo-signing and the implied covenant of good faith, but allowed plaintiffs claim alleging discovery of breaches of representations and warranties to proceed. On August 19, 2015, the Federal Deposit Insurance Corporation (FDIC) as receiver for a failed financial institution filed a civil action
against Citibank in the Southern District of New York. This action relates to one private-label RMBS trust for which Citibank formerly served as trustee. FDIC asserts claims for breach of contract, violation of the Streit Act, and violation of the
Trust Indenture Act. Citibank jointly briefed a motion to dismiss with The Bank of New York Mellon and U.S. Bank, N.A., entities that have also been sued by FDIC in their capacity as trustee, and these cases have all been consolidated in front of
Judge Carter. On September 30, 2016, the court granted the motion to dismiss without prejudice for lack of subject matter jurisdiction. On October 14, 2016, FDIC filed a motion for reargument or relief from judgment from the courts
dismissal order. On July 11, 2017, Judge Carter ruled on the motion for reconsideration regarding his dismissal of the action. He denied reconsideration of his decision on standing, but granted leave to amend the complaint by October 9,
2017. The FDIC subsequently requested an extension of time to file its amended complaint, which was granted. The FDIC filed its amended complaint on December 8, 2017. Defendants jointly filed a motion to dismiss the amended complaint on
March 13, 2018. On April 18, 2018, plaintiff filed its opposition. Defendants filed their joint reply on May 3, 2018. There can be no
assurances as to the outcome of litigation or the possible impact of litigation on the trustee or the RMBS trusts. However, Citibank denies liability and continues to vigorously defend against these litigations. Furthermore, neither the
above-disclosed litigations nor any other pending legal proceeding involving Citibank will materially affect Citibanks ability to perform its duties as Certificate Administrator under the pooling and servicing agreement for this CMBS
transaction.

Disclosure from Wells Fargo Bank, National Association, as certificate administrator and as custodian for
the Station Place III mortgage loan, the Capital Centers II & III mortgage loan and the Walgreens Witkoff Portfolio mortgage loan under the JPMDB 2017-C7 PSA, the Bank of America Office Campus
Building 600 mortgage loan under the UBS 2017-C4 PSA, the Mall of Louisiana mortgage loan under the BANK 2017-BNK7 PSA, the 50 Varick Street mortgage loan under the UBS
2017-C5 PSA, and the Chelsea Multifamily Portfolio mortgage loan and the Westin Crystal City mortgage loan under the CCUBS 2017-C1 PSA: Since June 18, 2014, a group of institutional investors have filed civil complaints in the Supreme Court of the State of New York, New York County, and
later the U.S. District Court for the Southern District of New York against Wells Fargo Bank, N.A., (Wells Fargo Bank) in its capacity as trustee for certain residential mortgage backed securities (RMBS) trusts. The
complaints against Wells Fargo Bank alleged that the trustee caused losses to investors and asserted causes of action based upon, among other things, the trustees alleged failure to: (i) notify and enforce repurchase obligations of
mortgage loan sellers for purported breaches of representations and warranties, (ii) notify investors of alleged events of default, and (iii) abide by appropriate standards of care following alleged events of default. Relief sought
included money damages in an unspecified amount, reimbursement of expenses, and equitable relief. Wells Fargo Bank has reached an agreement, in which it denies any wrongdoing, to resolve these claims on a classwide basis for the 271 RMBS trusts
currently at issue. The settlement agreement is subject to court approval. Separate lawsuits against Wells Fargo Bank making similar allegations filed by certain other institutional investors concerning 57 RMBS trusts in New York federal and state
court are not covered by the agreement. With respect to the foregoing litigations, Wells Fargo Bank believes plaintiffs claims are without merit and intends to contest the claims vigorously, but there can be no assurances as to the outcome of
the litigations or the possible impact of the litigations on Wells Fargo Bank or the RMBS trusts. Item 1119 of Regulation AB Provided previously in the prospectus of the Registrant relating to the issuing entity and filed on October 31, 2017 pursuant to Rule 424(b)(2) of the
Securities Act of 1933, as amended. Item 1122 of Regulation AB The reports on assessment of compliance with servicing criteria for asset-backed securities and related attestation reports are attached hereto under Item 15. 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 (Midland) 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 the assets backing the asset-backed securities covered in this Form 10-K report. 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 The servicer compliance statements are attached hereto under Item 15.
