EXPLANATORY NOTES



The Exhibit Index describes exhibits provided by certain parties (in their capacities indicated on the Exhibit Index) with respect to the 1000 Harbor Boulevard Mortgage Loan, which constituted approximately 0.5% of the asset pool of the issuing entity as of its cut-off date.  The 1000 Harbor Boulevard Mortgage Loan is an asset of the issuing entity and is part of a loan combination that includes the 1000 Harbor Boulevard Mortgage Loan and one other pari passu loan, which is not an asset of the issuing entity. The other pari passu portion of the loan combination was securitized in the UBS-Barclays Commercial Mortgage Trust 2012-C3 transaction, Commission File Number 333-177354-03 (the “UBS-Barclays 2012-C3 Transaction”). This loan combination, including the 1000 Harbor Boulevard Mortgage Loan, is being serviced and administered pursuant to the pooling and servicing agreement for the UBS-Barclays 2012-C3 Transaction, which is incorporated by reference as Exhibit 4.2 to this Annual Report on Form 10-K.



The master servicer of a pooling and servicing agreement or trust and servicing agreement also functions as the primary servicer of the related mortgage loans serviced and administered pursuant to such agreement unless a separate primary servicer is identified herein.  If this report does not identify a separate primary servicer, the servicer compliance statement provided by the master servicer under any such agreement also encompasses its responsibilities as primary servicer of the related mortgage loan or mortgage loans.



Rialto Capital Advisors, LLC is the special servicer of the mortgage loans serviced under the Pooling and Servicing Agreement and the 1000 Harbor Boulevard Mortgage Loan. As a result, Rialto Capital Advisors, LLC is a “servicer” as defined in Item 1108(a)(2)(iii) of Regulation AB, in the capacities described above, because it is servicing mortgage loans that constituted 10% or more of the assets of the issuing entity as of its cut-off date. The assessments of compliance with applicable servicing criteria, accountants’ attestation reports and servicer compliance statements delivered by Rialto Capital Advisors, LLC in the capacities described above are listed in the Exhibit Index.



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 under the Pooling and Servicing Agreement 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 servicing functions are included within the servicing criteria set forth in Items 1122(d)(4)(xi) and 1122(d)(4)(xii) of Regulation AB.  Therefore, under the principles-based definition of “servicer” set forth in Item 1101(j) of Regulation AB that looks to the functions that an entity performs, these vendors are “servicers” for the purposes of Item 1122 of Regulation AB.  See Compliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).



The assessment of compliance with applicable servicing criteria, accountants’ attestation report and servicer compliance statement of the certificate administrator of the 1000 Harbor Boulevard Mortgage Loan listed on the Exhibit Index is omitted from this Annual Report on Form 10-K as the certificate administrator pursuant to the related pooling and servicing agreement or trust and servicing agreement does not perform any activities that address servicing criteria with respect to the issuing entity and because it is not a “servicer” that meets the criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB.



With respect to the pari passu loan combination that includes the 1000 Harbor Boulevard Mortgage Loan, (i) the reports on assessment of compliance with servicing criteria and attestation reports on assessment of compliance with servicing criteria of Midland Loan Services, a Division of PNC Bank, National Association as primary servicer of the 1000 Harbor Boulevard Mortgage Loan, Deutsche Bank Trust Company Americas as trustee and custodian of the 1000 Harbor Boulevard Mortgage Loan and Park Bridge Lender Services LLC as operating advisor of the 1000 Harbor Boulevard Mortgage Loan, listed on the Exhibit Index are omitted from this Annual Report on Form 10-K as they are not required to be included on this Annual Report on Form 10-K per Instruction 3 to Item 1122 of Regulation AB because they are parties performing activities that address servicing criteria relating to 5% or less of the assets of the issuing entity; and (ii) the servicer compliance statement of Midland Loan Services, a Division of PNC Bank, National Association as primary servicer of the 1000 Harbor Boulevard Mortgage Loan, listed on the Exhibit Index is omitted from this Annual Report on Form 10-K as it is not required by Item 1123 of Regulation AB to be included on this Annual Report on Form 10-K because it is an unaffiliated party that is not a “servicer” that meets the criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB.

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 Deutsche Bank Trust Company Americas, as trustee and
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 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. As of March 1, 2020, both motions for summary judgment have been briefed and are awaiting decision by the
court.



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 1, 2020, both motions for summary judgment have been
briefed and are awaiting decision by the court.



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, 2020, 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 December 19, 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 4.1 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 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 1000 Harbor Boulevard Mortgage Loan, which is being serviced and administered pursuant to the pooling and servicing agreement for the UBS-Barclays 2012-C3 Transaction, are attached hereto under Item 15 to this Annual Report on Form 10-K. Attached as Schedule II to the pooling and servicing agreement for the UBS-Barclays 2012-C3 Transaction incorporated by reference as Exhibit 4.2 to this Annual Report on Form 10-K is a chart identifying the entities participating in a servicing function for the UBS-Barclays 2012-C3 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 ("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 fields as described in (1) and (2) below. (1) In connection with other enhancements Midland made to its manual
Schedule AL process, starting in April 2019, Midland developed and implemented new Schedule AL reporting templates for each
applicable CMBS transaction that closed prior to April 2019 and for each applicable CMBS transaction going forward. Related to this,
Midland made certain template setup errors, along with related and other manual inputting of information errors, and the errors were not
identified prior to submission of the applicable Schedule AL Files in certain cases due to breakdowns in quality control. (2) In one
applicable transaction, the related Schedule AL File for a given month was not saved properly resulting in the prior month's Schedule AL
File being submitted for the given month instead of the correct Schedule AL File.
| |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



Steps Taken to Remedy the Material Instance of Noncompliance



| |  | Midland’s Schedule AL reporting process was enhanced in April of 2019, however, the process remained manual throughout the 2019
calendar year. Errors relating to certain Schedule AL Files during 2019 were identified during the related audit. Following identification,
Midland made staffing changes and additional enhancements and improvements to its processes and procedures to support its Schedule AL
reporting obligations and expects to move to an automated solution for this process.
| |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Midland is currently remediating the Schedule AL reporting for certain of the CMBS transactions found to be incorrect.
| |  | ----------------------------------------------------------------------------------------------------------------------



Report on Assessment of Compliance with Applicable Servicing Criteria Not Included



| |  | For the reasons discussed in the Explanatory Notes above, Midland is not a party performing activities that address servicing criteria
relating to 5% or more of the assets of the issuing entity. Therefore, the report of assessment of compliance with applicable servicing
criteria for Midland has not been included as an exhibit to this Annual Report on Form 10-K.
| |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
