Item 1117 of Regulation AB: Legal Proceedings.



Barclays Bank Delaware (“BBD”)
is a defendant in a number of putative class action cases commenced in 2005 in various federal district courts by merchants alleging
that Visa U.S.A., Inc. (“Visa”), MasterCard International (“MasterCard”) and their member banks conspired
to fix interchange fees and unlawfully bundled several separate and distinct services, such as payment protection and transaction
processing costs, in violation of the U.S. antitrust laws. The merchants also allege that the defendants impose other restraints
on merchants in connection with accepting credit cards and that such alleged restraints violate the antitrust laws. Visa, MasterCard
and several other banks are also defendants in the proceedings, which have been consolidated into a single proceeding in the Eastern
District of New York. Several individual merchants also have commenced similar actions against Visa and MasterCard that have been
joined with the putative class actions for pre-trial purposes.

The merchants seek an unspecified amount
of damages and injunctive relief. By an order dated January 9, 2008, the court dismissed class damage claims prior to January 1,
2004; accordingly, the period over which any damages may be awarded is January 1, 2004 to the date of the award.

Pre-trial fact and expert discovery
have closed. Motions to dismiss the complaints in whole or in part, a motion to certify a class of retail plaintiffs and summary
judgment motions have been briefed, argued and submitted. Decisions on all motions were deferred pending the outcome of a proposed
settlement agreement.

On July 13, 2012, the parties filed
a proposed settlement agreement with the court under which the defendants agreed to pay the class plaintiffs $6.05 billion, to
make network rule changes and to give other relief. The settlement agreement also includes a provision pursuant to which Visa and
MasterCard would reduce U.S. interchange rates 10 bps during an eight month period from July 29, 2013 through March 29, 2014. On
the same day, defendants announced that they reached an agreement in principle to settle with a group of individual plaintiffs.
The class settlement was approved by District Judge John Gleeson on December 13, 2013. Judge Gleeson approved and entered an agreed
form of final judgment on January 14, 2014. The National Retail Federation and a number of merchants appealed that judgment to
the United States Court of Appeals for the Second Circuit. Oral argument was heard on September 28, 2015; and the parties continued
filing post argument briefs through November 2015. In addition, several of the merchants that have opted out of the settlement
(see below) have moved before the District Court of the Eastern District Court of New York to vacate the settlement due to alleged
improprieties conducted by an attorney for the plaintiff class and an attorney for one of the defendants. That motion could be
ruled on at anytime.







A number of merchants, including several
large retailers, have elected to “opt out” of the settlement. Opting out allows these merchants to commence separate
actions on these matters. Some of these merchants have commenced new actions against Visa, MasterCard and certain member banks.
Although the class settlement fund has been reduced to account for opt outs, opt out settlements may be higher than the amount
of that reduction. If so, BBD will be liable for a share of the residual under the terms of a judgment sharing agreement with the
defense group. As of the date of this prospectus, Visa and MasterCard have settled several of these opt-out actions and BBD has
contributed to the settlement of those actions in accordance with the judgement sharing agreement. The amount of those settlements
has exceeded what those plaintiffs would have been paid as a result of the class settlement. Only one opt out plaintiff has named
BBD as a defendant.

BBD is a defendant in an antitrust case filed on October 2, 2013 in the District Court of Victoria County,
Texas. In this case the plaintiffs allege that Visa, MasterCard and their respective member banks, among other things, conspired
in violation of Texas law to fix interchange fees, unlawfully bundle separate and distinct services, and impose various competitive
restraints. Plaintiffs seek unspecified damages and injunctive relief. Discovery is ongoing, and trial is currently scheduled to
begin on September 21, 2015.

On March 8, 2016, two merchants sued
BBD and 17 other defendants in federal court in San Francisco. The plaintiffs seek to represent a nationwide class of merchants
that accept Visa, MasterCard, American Express, Discover, JCP or UnionPay payment cards. The plaintiffs allege that the introduction
of “EMV” chip technology in payment cards disadvantages merchants in violation of federal and California antitrust
law, and California common law, because (a) merchants must buy new in-store card readers; and (b) after October 15, 2015, liability
for fraudulent in-store purchases paid for with payment cards was shifted to merchants that do not use EMV chip readers and those
merchants that have not had their EMV chip readers certified. Plaintiffs seek unspecified damages, trebled, and injunctive relief.
On March 14, 2016 plaintiffs moved for a preliminary injunction rescinding the liability shift. The court denied that motion on
March 16, 2016 before BBD or any other defendant submitted arguments in opposition to the motion. BBD’s response to the complaint
is currently due March 31, 2016. These proceedings are at a very preliminary stage, but BBD believes it has meritorious defenses
and intends to vigorously defend against these claims.

Given the inherent uncertainties involved
in these matters, it is too early to reliably estimate the ultimate liability BBD may incur or whether the results could be material
to the operation or cash flows of BBD.

Substitute information provided in accordance with General
Instruction J to Form 10–K:



Item 1119 of Regulation AB: Affiliations and Certain
Relationships and Related Transactions.

Information required by
Item 1119 of Regulation AB has been omitted from this report on Form 10-K in reliance on the Instruction to Item 1119.

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

Each of BBD, Barclays Bank PLC (“BBPLC”),
REMITCO LLC and U.S. Bank National Association (each, a “Servicing Participant”) has been identified by the registrant
as a party participating in the servicing function with respect to the pool assets held by the Trust. Each Servicing Participant
has completed a report on an assessment of compliance with the servicing criteria applicable to such Servicing Participant (each,
a “Report on Assessment”) as of, and for the period from January 1, 2015 to December 31, 2015, which Reports on Assessment
are included as exhibits to this Form 10-K. In addition, each Servicing Participant has provided an attestation report (each, an
“Attestation Report”) by a registered independent public accounting firm regarding its related Report on Assessment.
Each Attestation Report is attached as an exhibit to this Form 10-K.

Vendors

A Servicing Participant may engage
one or more vendors to perform specific and limited, or scripted activities that address all or a portion of one or more servicing
criteria applicable to such Servicing Participant. In general in these cases, the Servicing Participant has instituted policies
and procedures to monitor whether such vendors’ activities comply in all material respects with such servicing criteria,
and may elect to take responsibility for assessing compliance with the servicing criteria applicable to such vendors’ activities
in such Servicing Participant’s Report on Assessment. Where the Servicing Participant has not instituted such policies and
procedures, or where the Servicing Participant does not otherwise elect to take responsibility for assessing its vendors’
activities, the vendor is itself treated as a Servicing Participant and is required to provide its own Report on Assessment and
related Attestation Report.

Exceptions

No Report on Assessment or related
Attestation Report has identified: (i) any material instance of noncompliance with the servicing criteria identified in such Report
on Assessment as applicable to the related Servicing Participant or (ii) any material deficiency in such Servicing Participant’s
policies and procedures to monitor vendor compliance.

Platform-Level Reports

Regulations of the Securities and Exchange
Commission (the “SEC”) require that each Servicing Participant complete a Report on Assessment at a “platform”
level, meaning that the transactions covered by the Report on Assessment should include all asset-backed securities transactions
involving such Servicing Participant that are backed by the same asset type. Further guidance from the SEC staff identifies additional
parameters which a Servicing Participant may apply to define and further limit its platform. Each Servicing Participant is responsible
for defining its own platform, and each platform will naturally differ based on various factors, including the Servicing Participant’s
business model, the transactions in which it is involved and the range of activities performed in those transactions.

Based on our understanding of their
platforms and the guidance that is available at this time, we believe that the parameters by which the Servicing Participants have
defined their platforms should be permissible. However, because the guidance available at this time is subject to clarification
or change, we cannot assure you that the SEC and its staff will necessarily agree.

Item 1123 of Regulation AB: Servicer Compliance Statement.

Each of BBD and BBPLC has been identified
by the registrant as a servicer meeting the criteria of Item 1108(a)(2)(i), (ii) or (iii) of Regulation AB with respect to the
pool assets held by the Trust. Each of these servicers has provided a statement of compliance (a “Compliance Statement”),
which has been signed by an authorized officer of such related servicer. Each Compliance Statement is attached as an exhibit to
this Form 10-K.
