Item 1112(b) of Regulation AB. Significant Obligors of Pool
Assets (Financial Information).

Item 1114(b)(2) of Regulation AB: Credit Enhancement and

Item 1117 of Regulation AB: Legal Proceedings.

Except as set forth below, there are no legal
proceedings pending (or proceedings known to be contemplated by governmental authorities) against any of Barclays Bank Delaware, Barclays
Dryrock Funding LLC, U.S. Bank National Association, Wilmington Trust, National Association or Barclays Dryrock Issuance Trust, or of
which any property of the foregoing is subject, that are material to holders of the notes.

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 bundle
several separate and distinct services, such as payment protection and transaction processing costs, in violation of the U.S. antitrust
laws. The merchants also alleged that the defendants imposed other restraints on merchants in connection with accepting payment cards
and that such alleged restraints violated the antitrust laws. Visa, MasterCard and several other payment card issuing banks are also defendants
in the proceedings, which have been consolidated into a single proceeding in the Eastern District of New York, MDL No. 1720.







The merchants’ complaints sought 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.

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 “2012 class settlement”). The 2012 class settlement included 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
that were not members of the class. The 2012 class settlement was approved by District Judge John Gleeson on December 13, 2013, who then
entered an agreed form of final judgment on January 14, 2014.

A number of merchants, including several large
retailers, elected against participation in the 2012 class settlement, “opting out” of that settlement and pursuing separate
actions on the same or similar claims as those alleged by the putative class plaintiffs. Some of these merchants commenced new actions
against Visa, MasterCard, and certain member banks, not including BBD, which remain pending. Although the class settlement fund was reduced
to account for opt-outs, resulting in a refund to BBD of a portion of its share of the class settlement fund, total settlement payments
by BBD to opt-out plaintiffs may be higher than the amount of that refund. If so, BBD will be liable for its share of the excess over
the refund under the terms of a judgment sharing agreement with Visa, MasterCard, and the other payment card issuing bank defendants.
As of the date hereof, Visa and MasterCard have settled a number of these opt-out actions and BBD has contributed to the settlement of
those actions in accordance with the judgment sharing agreements. The amount of those settlements has exceeded what each of those plaintiffs
would have been paid as a result of the 2012 class settlement.

The National Retail Federation and a number of
merchants appealed the judgment entering the 2012 class settlement to the United States Court of Appeals for the Second Circuit. On June
30, 2016, the Second Circuit reversed District Judge Gleeson’s ruling approving the 2012 class settlement and remanded the action
back to the Eastern District of New York.

Following remand of the case, the District Court
reappointed counsel to represent members of the putative class seeking primarily (but not exclusively) damages pursuant to Federal Rule
of Civil Procedure 23(b)(3) and appointed new counsel to represent class members seeking primarily equitable relief pursuant to Federal
Rule of Civil Procedure 23(b)(2).

Counsel for the Rule 23(b)(3) putative class
members moved for leave to file an amended complaint adding factual allegations and legal theories to conform to developments in the law,
as well as damage claims for additional years of alleged damages. On September 27, 2017, Magistrate Judge James Orenstein granted the
Rule 23(b)(3) plaintiffs’ motion to amend in part and denied it in part, allowing the plaintiffs to amend their complaints to add
their additional legal and factual theories, but holding that those theories would only apply to the preceding four years and would not
relate back to the date of filing of the initial complaints in 2005. On October 30, 2017, the Rule 23(b)(3) plaintiffs filed their amended
complaint.

The Rule 23(b)(3) plaintiffs also appealed Magistrate
Judge Orenstein’s ruling to District Judge Margo Brodie. On August 30, 2018, District Judge Brodie set aside Magistrate Judge Orenstein’s
ruling, holding that plaintiffs’ additional legal and factual theories related back to the original filing dates for the Rule 23(b)(3)
complaints and, for similar reasons, that comparable theories advanced by merchants that elected not to participate in the 2012 class
settlement and are suing the same defendants separately were entitled to have had their claims considered to be tolled such that they
would be treated as timely.

Counsel for the Rule 23(b)(2) putative class
members filed a separate complaint seeking broad equitable relief against allegedly anticompetitive conduct as well as Visa and MasterCard
network rules (the “Rule 23(b)(2) Class Action”). On January 16, 2019, BBD and the other bank defendants moved to dismiss
the Rule 23(b)(2) class plaintiffs’ claims.  On November 20, 2019, the Court denied the bank defendants’ motion to dismiss.
BBD and the other bank defendants filed answers to the complaint on May 18, 2020. On June 1, 2020, defendants
and the Rule 23(b)(2) class plaintiffs each moved for summary judgment on various issues, which motions have been fully briefed as of
December 21, 2020 and are pending before the District Court. On December 18, 2020, the Rule 23(b)(2) class plaintiffs moved to certify a class, and District
Judge Brodie granted the motion for class certification on September 27, 2021.









On February 17, 2017, BBD was named as a defendant
in a case filed in Harris County Texas District Court (the “Texas Action”). Plaintiffs alleged that Visa, MasterCard,
and the named defendant member banks agreed, with respect to Visa and MasterCard branded payment cards, to fix interchange fees, unlawfully
bundle separate and distinct services, and otherwise engage in monopolistic and anticompetitive behavior in violation of the Texas Free
Enterprise and Antitrust Act of 1983. Plaintiffs sought unspecified damages and injunctive relief. On April 5, 2017, defendants jointly
removed the case to the U.S. District Court for the Southern District of Texas, and on August 3, 2017, the action was transferred to the
Eastern District of New York to be included in the pending multi-district litigation, MDL No. 1720. On November 26, 2018, plaintiffs filed
a second amended complaint adding claims for violation of Sections I and II of the Sherman Antitrust Act against all defendants. BBD answered
the second amended complaint on December 21, 2018. Pursuant to the terms of a confidential settlement, plaintiffs dismissed their claims
with prejudice on May 4, 2020. BBD has contributed to the settlement of this action in accordance with the judgment sharing agreements.
The Texas Action is now concluded.

On September 17, 2018, all defendants entered
into a settlement agreement with the Rule 23(b)(3) class plaintiffs to resolve their claims (the “Settlement Agreement”). 
The Settlement Agreement amends and supersedes the 2012 class settlement. The Settlement Agreement resolves the damages claims of the
plaintiffs in the interchange fee litigation pending in the United States District Court for the Eastern District of New York, subject
to any of those plaintiffs choosing to opt out of the Settlement Agreement and pursue their own actions, with the class plaintiffs agreeing
to receive $6.20 billion to settle this matter. BBD has contributed to the class settlement in accordance with the judgment sharing agreements.
On December 13, 2019, the United States District Court for the Eastern District of New York granted final approval of the Settlement Agreement
(the “(b)(3) Class Settlement Final Approval”). Several objectors have filed appeals in connection with the (b)(3)
Class Settlement Final Approval. The appeals have been fully briefed, and the Second Circuit is scheduled hear the appeals on March 16,
2022.

On July 20, 2019, forty-five merchants filed
an opt-out suit in the Northern District of California, asserting claims against Visa and MasterCard that are generally similar to the
claims raised by the Rule 23(b)(3) plaintiffs. This suit was transferred to the Eastern District of New York to be coordinated with the
MDL No. 1720 proceedings. Since July 2019, several additional opt-out claims have been initiated, and BBD anticipates that additional
opt-out claims may be initiated. While the Settlement Agreement provides that the class settlement fund will be reduced to account for
opt-outs, resulting in a refund to BBD of a portion of its share of the class settlement fund provided by the Settlement Agreement, total
settlement payments by BBD to opt-out plaintiffs that opt out of the Settlement Agreement may be higher than the amount of that refund.
If so, BBD will be liable for its share of the excess over the refund under the terms of a judgment sharing agreement with Visa, MasterCard,
and the other payment card issuing bank defendants. As of the date hereof, Visa and MasterCard have settled a number of these additional
opt-out actions, and BBD has contributed to the settlement of those actions in accordance with the judgment sharing agreements.

Because of the inherent uncertainties involved
in the Rule 23(b)(2) Class Action, the “opt-out” plaintiffs’ actions arising from the 2012 class settlement, and the
prospect of additional “opt-out” plaintiffs’ actions arising from the Settlement Agreement, 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. Any reduction
in the interchange fees paid by merchants to banks could adversely impact the business operations of credit card issuers, such as BBD,
and could reduce the amount of interchange included in finance charge collections.
