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

 The primary asset of Discover Card Execution Note Trust (the " Note Issuance Trust ") is the Discover Card Master Trust I,
Series 2007-CC collateral certificate, which represents an undivided interest in Discover Card Master Trust I (the " Master Trust "), whose assets include Discover Card receivables existing as
of specified dates in designated accounts, which receivables have been transferred to the Master Trust by Discover Bank and Discover Funding LLC, as applicable. The investor interest in receivables for the collateral certificate reflects the
aggregate nominal liquidation amount of notes issued by the Note Issuance Trust. The Master Trust, therefore, may be considered a significant obligor in relation to the Note Issuance Trust. Pursuant to Instruction 3.b. to Item 1112(b) of
Regulation AB, the information required by Instruction J to Form 10-K in respect of the Master Trust has been disclosed in this report on Form 10-K in lieu of the

 Item 1117 of
Regulation AB. Legal Proceedings.
 Discover Bank

 In the normal course of business, from time to time, Discover Bank and/or one or more of its affiliates have been named as a defendant in
various legal actions, including arbitrations, class actions, and other litigation, arising in connection with our activities. Certain of the actual or threatened legal actions include claims for substantial compensatory and/or punitive damages or
claims for indeterminate amounts of damages. Discover Bank contests liability and/or the amount of damages as appropriate in each pending matter.

 Discover Bank and its affiliates are also involved, from time to time, in other reviews, investigations and proceedings (both formal and
informal) by governmental regulatory and enforcement agencies regarding its business, including, among other matters, accounting, tax and operational matters, some of which may result in adverse judgments, settlements, fines, penalties, injunctions,
decreases in regulatory ratings or other relief, which could materially impact Discover Bank's financial results, increase its cost of operations, require a change in business activities and product offerings or limit its ability to execute its
business strategies and engage in certain business activities.

 In July 2015, Discover Bank, The Student Loan Corporation ("SLC") and Discover
Products Inc. ("DPI") agreed to a consent order with the Consumer Financial Protection Bureau ("CFPB") with respect to certain private student loan servicing practices (the "2015 Order"). The 2015 Order expired in July
2020. In December 2020, Discover Bank, SLC and DPI agreed to a consent order (the "2020 Order") with the CFPB resolving the agency's investigation into Discover Bank's compliance with the 2015 Order. In connection with the 2020
order, Discover is required to implement a redress and compliance plan and must pay at least $10 million in consumer redress to consumers who may have been harmed and paid a $25 million civil money penalty to the CFPB.

 On September 25, 2023, following the consent of the Board of Directors of Discover Bank, the FDIC issued a consent order to Discover Bank
(the "2023 Consent Order"). The 2023 Consent Order addresses shortcomings in Discover Bank's compliance management system for consumer protection laws and related matters. As part of the 2023 Consent Order, Discover Bank has agreed to
improve its consumer compliance management system and enhance related corporate governance and enterprise risk management practices, and increase the level of Board of Director oversight over such matters. Discover Bank has been taking significant
steps to strengthen the organization's compliance management system and address the other issues identified in the 2023 Consent Order. The 2023 Consent Order does not contain any monetary penalties or fines.

 U.S. Bank Trust Company, National Association (Successor to U.S. Bank National Association)

 U.S. Bank Trust Company, National Association, a national banking association ("U.S. Bank Trust Co."), will act as the indenture
trustee for the note issuance trust, also acts as trustee for the master trust and as registrar and paying agent under the Pooling and Servicing Agreement and the series supplement for Series 2007-CC and the
other series of master trust certificates, if any.
 U.S. Bank National Association ("U.S. Bank N.A.") made a strategic decision
to reposition its corporate trust business by transferring substantially all of its corporate trust business to its affiliate, U.S. Bank Trust Co., a non-depository trust company (U.S. Bank N.A. and U.S. Bank
Trust Co. are collectively referred to herein as "U.S. Bank."). Upon U.S. Bank Trust Co.'s succession to the business of U.S. Bank N.A., it became a wholly owned subsidiary of U.S. Bank N.A. The Indenture Trustee will maintain the
accounts of the issuing entity in the name of the Indenture Trustee at U.S. Bank N.A.
 U.S. Bancorp, with total assets
exceeding $663 billion as of December 31, 2023, is the parent company of U.S. Bank N.A., the fifth largest commercial bank in the United States. As of December 31, 2023, U.S. Bancorp operated over 2,200 branch offices in 26 states. A
network of specialized U.S. Bancorp offices across the nation provides a comprehensive line of banking, brokerage, insurance, investment, mortgage, trust and payment services products to consumers, businesses, and institutions.

 U.S. Bank has one of the largest corporate trust businesses in the country with office locations in 48 domestic and 2 international cities.
The Pooling and Servicing Agreement and the indenture will be administered from U.S. Bank's corporate trust office located at 190 South LaSalle Street, 7th Floor, Chicago, IL 60603.

 U.S. Bank has provided corporate trust services since 1924. As of December 31, 2023, U.S. Bank was acting as trustee with respect to over
130,000 issuances of securities with an aggregate outstanding principal balance of over $5.9 trillion. This portfolio includes corporate and municipal bonds, mortgage-backed and asset-backed securities and collateralized debt obligations.

 As trustee, paying agent, and registrar with respect to the master trust, U.S. Bank Trust Co. will make each certificateholders' monthly
statement available to the certificateholders and noteholders via the master trust trustee's internet website at  Noteholders with questions may direct them to the master trust trustee's bondholder services group
at (800) 934-6802.

 As of December 31, 2023, U.S. Bank (and its affiliate U.S. Bank Trust National
Association) was acting as indenture trustee, registrar and paying agent on 45 issuances of credit card receivables-backed securities with an outstanding aggregate principal balance of approximately $29,376,600,000.

 U.S. Bank N.A. and other large financial institutions have been sued in their capacity as trustee or successor trustee for certain residential
mortgage-backed securities ("RMBS") trusts. The complaints, primarily filed by investors or investor groups against U.S. Bank N.A. and similar institutions, allege the trustees caused losses to investors as a result of alleged failures by
the sponsors, mortgage loan sellers and servicers to comply with the governing agreements for these RMBS trusts. Plaintiffs generally assert causes of action based upon the trustees' purported failures to enforce repurchase obligations of
mortgage loan sellers for alleged breaches of representations and warranties, notify securityholders of purported events of default allegedly caused by breaches of servicing standards by mortgage loan servicers and abide by a heightened standard of
care following alleged events of default.
 U.S. Bank N.A. denies liability and believes that it has performed its obligations under the
RMBS trusts in good faith, that its actions were not the cause of losses to investors, that it has meritorious defenses, and it has contested and intends to continue contesting the plaintiffs' claims vigorously. However, U.S. Bank N.A. cannot
assure you as to the outcome of any of the litigation, or the possible impact of these litigations on the trustee or the RMBS trusts.
 On
March 9, 2018, a law firm purporting to represent fifteen Delaware statutory trusts (the "DSTs") that issued securities backed by student loans (the "Student Loans") filed a lawsuit in the Delaware Court of Chancery against
U.S. Bank N.A. in its capacities as indenture trustee and successor special servicer, and three other institutions in their respective transaction capacities, with respect to the DSTs and the Student Loans. This lawsuit is captioned The National
Collegiate Student Loan Master Trust I, et al. v. U.S. Bank National Association, et al., C.A. No. 2018-0167-JRS (Del. Ch.) (the "NCMSLT Action"). The complaint, as amended on June 15, 2018,
alleged that the DSTs have been harmed as a result of purported misconduct or omissions by the defendants concerning administration of the trusts and special servicing of the Student Loans. Since the filing of the NCMSLT Action, certain Student Loan
borrowers have made assertions against U.S. Bank N.A. concerning special servicing that appear to be based on certain allegations made on behalf of the DSTs in the NCMSLT Action.

 U.S. Bank N.A. has filed a motion seeking dismissal of the operative complaint in its entirety with prejudice pursuant to Chancery Court Rules
12(b)(1) and 12(b)(6) or, in the alternative, a stay of the case while other prior filed disputes involving the DSTs and the Student Loans are litigated. On November 7, 2018, the Court ruled that the case should be stayed in its entirety
pending resolution of the first-filed cases. On January 21, 2020, the Court entered an order consolidating for pretrial purposes the NCMSLT Action and three other lawsuits pending in the Delaware Court of Chancery concerning the DSTs and the
Student Loans, which remains pending.
 U.S. Bank N.A. denies liability in the NCMSLT Action and believes it has performed its obligations
as indenture trustee and special servicer in good faith and in compliance in all material respects with the terms of the agreements governing the DSTs and that it has meritorious defenses. It has contested and intends to continue contesting the
plaintiffs' claims vigorously.

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

 Discover Bank, which acts as the sponsor of its securitizations, is a wholly owned subsidiary of Discover Financial Services. Discover
Funding LLC, which is a wholly owned subsidiary of Discover Bank, acts as depositor and beneficiary for the Note Issuance Trust and as holder of the residual transferor interest of the Master Trust. Discover Financial Services acquired Discover Bank
in January 1985. Discover Bank and the trustee for the Master Trust formed the Master Trust in October 1993. Discover Bank originates the credit card receivables generated under certain designated Discover card accounts and transfers such credit
card receivables to Discover Funding LLC for further transfer to the Master Trust. Discover Bank and the owner trustee formed the Note Issuance Trust on July 2, 2007. Discover Bank transferred an undivided interest in the receivables and other
assets of the Master Trust, represented by the collateral certificate, to the Note Issuance Trust to support the issuance of notes on July 26, 2007.

 Discover Bank acts as master servicer for the Master Trust and is currently the only servicer under the Pooling and Servicing Agreement with
respect to the receivables. During the reporting period, Discover Bank outsourced certain servicing functions to its affiliate, DPI. While DPI has contracted with third-party service providers for certain services, Discover Bank is ultimately
responsible for the overall servicing function. Discover Bank also acts as calculation agent for the Note Issuance Trust, which is part of the servicing function.

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

 Each of Discover Bank, DPI and U.S. Bank Trust Company, National Association (each, a " Servicing Participant ") has been
identified as a party participating in the servicing function during the reporting period with respect to the pool assets held by each of the Master Trust and the Note Issuance Trust. Each of Discover Bank, DPI and U.S. Bank Trust Company, National
Association has completed a report on an assessment of compliance with the servicing criteria applicable to such Servicing Participant (each, a " Report on Assessment ") during the year ended December 31, 2023, which Reports on
Assessment are attached as exhibits to this Form 10-K. In addition, each of Discover Bank, DPI and U.S. Bank Trust Company, National Association 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. None
of the Reports on Assessment or the related Attestation Reports has identified any material instances of noncompliance with the servicing criteria applicable to such Servicing Participant described in the related Report on Assessment.

 Item 1123 of Regulation AB. Servicer Compliance Statement.

 Each of Discover Bank and DPI has been identified as a servicer during the reporting period with respect to the pool assets held by each of the
Master Trust and the Note Issuance Trust. Each of Discover Bank and DPI has provided a statement of compliance (each, a " Compliance Statement ") with respect to the servicing activities conducted during the Note Issuance Trust's
