EXPLANATORY NOTES

The Sullivan Center Mortgage Loan, which constituted approximately 10.3% of the asset pool of the issuing entity as of its cut-off date, is an asset of the issuing entity and is part of a loan combination that includes the Sullivan Center Mortgage Loan and one other pari passu loan, which is not an asset of the issuing entity. This loan combination, including the Sullivan Center Mortgage Loan, is being serviced and administered pursuant to the Pooling and Servicing Agreement, which is incorporated by reference as Exhibit 4.1 to this Annual Report on Form 10-K.

The Exhibit Index describes exhibits provided by certain parties (in their capacities indicated on the Exhibit Index) with respect to The Outlet Collection | Jersey Gardens Mortgage Loan, which constituted approximately 17.9% of the asset pool of the issuing entity as of its cut-off date. The Outlet Collection | Jersey Gardens Mortgage Loan is an asset of the issuing entity and is part of a loan combination that includes The Outlet Collection | Jersey Gardens Mortgage Loan and two other pari passu loans, which are not assets of the issuing entity.  One of the other pari passu portions of the loan combination was securitized in the WFCM Commercial Mortgage Trust 2013-C18 transaction, Commission File Number 333-172366-11 (the “WFCM 2013-C18 Transaction”). This loan combination, including The Outlet Collection | Jersey Gardens Mortgage Loan, is being serviced and administered pursuant to the pooling and servicing agreement for the WFCM 2013-C18 Transaction, which is incorporated by reference as Exhibit 4.2 to this Annual Report on Form 10-K.

This Annual Report on Form 10‑K includes assessments of compliance with applicable servicing criteria and accountants’ attestation reports from CoreLogic Commercial Real Estate Services, Inc. and National Tax Search, LLC. These entities were engaged by the master servicer and the primary servicer for The Outlet Collection | Jersey Gardens Mortgage Loan, to remit tax payments received from the escrow accounts of borrowers to local taxing authorities, to report tax amounts due, to verify tax parcel information, and to verify non-escrow tax payments. These services are included within the servicing criteria set forth in Items 1122(d)(4)(xi) and 1122(d)(4)(xii). Therefore, under the principles-based definition of “servicer” set forth in Item 1101(j) that looks to the functions that an entity performs, these vendors are “servicers” for the purposes of Item 1122. See Compliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).

Deutsche Bank Trust Company Americas acts as trustee of the issuing entity and The Outlet Collection | Jersey Gardens Mortgage Loan. Pursuant to the Pooling and Servicing Agreement and the pooling and servicing agreement with respect to the WFCM 2013-C18 Transaction, the trustee is required to provide an assessment of compliance with applicable servicing criteria solely with respect to Item 1122(d)(2)(iii) of Regulation AB (regarding advances of funds or guarantees regarding collections, cash flows or distributions, and any interest or other fees charged for such advances, are made, reviewed and approved as specified in the transaction agreements). However, the trustee is not required to deliver such assessment of compliance with applicable servicing criteria with respect to any reporting period during which there were no servicing criteria applicable to the trustee, as was the case during the reporting period covered by this Annual Report on Form 10‑K. As a result, this Annual Report on Form 10‑K does not include an assessment of compliance with applicable servicing criteria of the trustee. The assessment of compliance with applicable servicing criteria of the master servicer covers Item 1122(d)(2)(iii) of Regulation AB.

Item 1117 of Regulation AB, Legal Proceedings. UBSRES is currently engaged in

The registrant knows of no material pending legal proceedings involving the Trust or any party related to such Trust, other than routine litigation incidental to the duties of those respective parties, and the following, with respect to various legacy residential mortgage-backed securities transactions. Some litigants are seeking the repurchasewith respect to Deutsche Bank Trust Company Americas, as trustee, and Wells Fargo Bank, National Association, as certificate administrator:

Deutsche Bank Trust Company Americas (“DBTCA”) has been named as a defendant in civil litigation concerning its role as trustee of mortgage loans by UBSRES from certain residential mortgage securitizationbacked securities (“RMBS”) trusts. On June 18, 2014, a group of investors (“Plaintiff Investors”) filed a civil action against DBTCA and Deutsche Bank National Trust Company (“DBNTC”) in New York State Supreme Court purportedly on behalf of and for the benefit of 544 private-label RMBS trusts asserting claims for alleged violations of the Trust Indenture Act of 1939, breach of contract, breach of fiduciary duty and negligence based on DBTCA’s and DBNTC’s alleged failure to perform their obligations as trustees for the basistrusts (the “NY Derivative Action”). An amended complaint was filed on July 16, 2014, adding Plaintiff Investors and RMBS trusts to the NY Derivative Action. On November 24, 2014, the Plaintiff Investors moved to voluntarily dismiss the NY Derivative Action without prejudice. Also on November 24, 2014, substantially the same group of Plaintiff Investors filed a civil action against DBTCA and DBNTC in the United States District Court for the Southern District of New York (the “SDNY Action”), making substantially the same allegations as the New York Derivative Action with respect to 564 RMBS trusts (542 of which were at issue in the NY Derivative Action). The SDNY Action is styled both as a derivative action on behalf of the named RMBS Trusts and, in the alternative, as a putative class action on behalf of holders of RMBS representing interests in those RMBS trusts. DBTCA is vigorously defending the SDNY Action. DBTCA has no pending legal proceedings (including, based on DBTCA’s present evaluation, the litigation disclosed in this paragraph) that would materially affect its ability to perform its duties as Trustee on behalf of the Certificateholders.

On June 18, 2014, a group of institutional investors filed a civil complaint in the Supreme Court of the State of New York, New York County, against Wells Fargo Bank, National Association (“Wells Fargo Bank”), in its capacity as trustee under 276 residential mortgage backed securities ("RMBS") trusts, which was later amended on July 18, 2014, to increase the number of trusts to 284 RMBS trusts. On November 24, 2014, the plaintiffs filed a motion to voluntarily dismiss the state court action without prejudice. That same day, a group of institutional investors filed a civil complaint in the United States District Court for the Southern District of New York against Wells Fargo Bank, alleging claims against the bank in its capacity as trustee for 274 RMBS trusts (the “Complaint”). In December 2014, the plaintiffs’ motion to voluntarily dismiss their original state court action was granted. As with the prior state court action, the Complaint is one of six similar complaints filed contemporaneously against RMBS trustees (Deutsche Bank, Citibank, HSBC, Bank of New York Mellon and US Bank) by a group of institutional investor plaintiffs. The Complaint against Wells Fargo Bank alleges that the loans are allegedly in breachtrustee caused losses to investors and asserts causes of contractualaction based upon, among other things, the trustee's alleged failure to (i) enforce repurchase obligations of mortgage loan sellers for purported breaches of representations and warranties, (ii) notify investors of alleged events of default purportedly caused by breaches by mortgage loan servicers, and (iii) abide by appropriate standards of care following alleged events of default. Relief sought includes money damages in governing transaction documents.an unspecified amount, reimbursement of expenses, and equitable relief. Other litigants arecases alleging violationssimilar causes of federal and/or state securities or common law for alleged misrepresentationsaction have been filed against Wells Fargo Bank and omissionsother trustees by RMBS investors in offering documents in connection with the issuance and/or distribution of residential mortgage-backed securities. No assurancethese and other transactions. There can be given that one or moreno assurances as to the outcome of the foregoinglitigation, or the possible impact of the litigation on the trustee or the RMBS trusts. However, Wells Fargo Bank denies liability and believes that it has performed its obligations under the RMBS trusts in good faith, that its actions willwere not result in material liabilitythe cause of any losses to UBSRES. investors, and that it has meritorious defenses, and it intends to contest the plaintiffs’ claims vigorously.
