Supplement, as may be further amended, restated, amended and restated, supplemented, replaced or otherwise modified from time to time, is herein called the “Indenture Supplement”), between the Issuer and Indenture Trustee, to which
Indenture and Indenture Supplement reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. The Class A(2012-A) Notes are subject to all terms of
the Indenture, the Indenture Supplement, the Terms Document for the Class A(2012-A) Notes, dated as of March 29, 2012 (such Terms Document, as amended, restated, amended and restated, supplemented, replaced or otherwise modified from time to

the Note Issuance Trust and Discover Bank (such Fee Letter, as amended, restated, amended and restated, supplemented, replaced or otherwise modified from time to time, is herein called the “Fee Letter”). All terms used in this Class
A(2012-A) Note that are defined in the Indenture, the Indenture Supplement and the Terms Document shall have the meanings assigned to them in or pursuant to the Indenture, the Indenture Supplement and the Terms Document. 

The Class B Notes, the Class C Notes and the Class D Notes of the DiscoverSeries and other tranches of Class A Notes of the
DiscoverSeries will also be issued under the Indenture and the Indenture Supplement. 
 The Class A(2012-A) Notes are and will
be equally and ratably secured by the collateral pledged as security therefor as provided in the Indenture and the Indenture Supplement. 
 Principal of the Class A(2012-A) Notes will be payable on or prior to the Expected Maturity Date, or, if such date is extended pursuant to the Note Purchase Agreement, the Existing Expected Maturity Date

without requiring that this Class A(2012-A) Note be submitted for notation of payment. Any reduction in the principal amount of this Class A(2012-A) Note (or any one or more Predecessor Notes) effected by any payments made on any Payment Date shall
be binding upon all future Holders of this Class A(2012-A) Note and of any Class A(2012-A) Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. If funds are expected to be
available, as provided in the Indenture, for payment in full of the then remaining unpaid principal amount of this Class A(2012-A) Note on a Payment Date occurring after the Purchase Commitment Termination Date (as defined in the Note Purchase

Class A(2012-A) Note, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange. 

To the fullest extent permitted by applicable law, each Noteholder or Note Owner, by acceptance of a Class A(2012-A) Note or, in the case
of a Note Owner, a beneficial interest in a Class A(2012-A) Note, covenants and agrees that by accepting the benefits of the Indenture that it will not, prior to the date that is one year and one day after the later of (i) the termination of

Issuer to invoke the process of any Governmental Authority for the purpose of commencing or sustaining a case against the Master Trust or the Issuer under any Federal or state bankruptcy, insolvency or similar law or appointing a receiver,
liquidator, assignee, trustee, custodian, sequestrator or other similar official of the Master Trust or the Issuer or any substantial part of its property or ordering the winding-up or liquidation of the affairs of the Master Trust or the Issuer.

 Prior to the due presentment for registration of transfer of this Class A(2012-A) Note, the Issuer, the Indenture Trustee and
any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Class A(2012-A) Note (as of the day of determination or as of such other date as may be specified in the Indenture) is registered as the owner hereof for all
purposes, whether or not this Class A(2012-A) Note be overdue, and neither the Issuer, the Indenture Trustee nor any such agent shall be affected by notice to the contrary.

the Indenture at any time by the Issuer with the consent of the Holders of Notes representing not less than 66 2/3% of the Outstanding Dollar Principal Amount of each adversely affected Series, Class or Tranche of Notes. The Indenture also contains
provisions permitting the Holders of Notes representing specified percentages of the Outstanding Dollar Principal Amount of the Notes, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Class A(2012-A) Note shall be conclusive and binding upon such Holder and upon all future Holders of this Class
A(2012-A) Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this Class A(2012-A) Note. The Indenture also permits the Indenture
Trustee to amend or waive certain terms and conditions set forth in the Indenture without the consent of Holders of the Notes issued thereunder.

 The transfer of
this Note is subject to certain restrictions set forth in the Note Purchase Agreement. In no event shall this Note, or any interest therein, be transferred to an employee benefit plan, trust or account subject to the Employee Retirement Income
Security Act of 1974, as amended (“ERISA”), or described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the “Code”), and not excepted under Section 4975(g). Any Holder of this Note or, in the
case of a Note Owner, a beneficial interest in a Class A(2012-A) Note, by its acceptance hereof, shall be deemed to represent and warrant that it is not (i) an employee benefit plan (as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended, or a plan described in Section 4975(e)(l) of the Code, (ii) purchasing any Note or any interest therein on behalf of any such plan as investment manager, named fiduciary or trustee of any such plan,
or (iii) purchasing any Note or interest therein with any assets of any plan within the meaning of 29 CFR Section 2510.3-101. 
 The Class A(2012-A) Notes are issuable only in registered form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 

THIS CLASS A(2012-A) NOTE AND THE INDENTURE WILL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK,
INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATION LAW, WITHOUT REFERENCE TO ANY CONFLICT OF LAW PROVISIONS THAT WOULD RESULT IN THE APPLICATION OF THE LAWS OF ANY OTHER STATE. 

No reference herein to the Indenture and no provision of this Class A(2012-A) Note or of the Indenture shall alter or impair the
obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Class A(2012-A) Note at the times, place, and rate, and in the coin or currency herein prescribed. 

No recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer on the Notes or under the Indenture or
any certificate or other writing delivered in connection therewith, against (i) the Owner Trustee in its individual capacity, (ii) any owner of a beneficial interest in the Issuer or (iii) any partner, owner, beneficiary, agent,
officer, director or employee of the Owner Trustee in its individual capacity, any holder of a beneficial interest in the Issuer or any successor or assign of the Owner Trustee in its individual capacity, except as any such Person may have expressly
agreed (it being understood that the Owner Trustee has no such obligations in its individual capacity). The Holder of this Class A(2012-A) Note by the acceptance hereof agrees that, except as expressly provided in the Indenture and the Indenture
Supplement in the case of an Event of Default under the Indenture, the Holder shall have no claim against any of the foregoing for any deficiency, loss or claim therefrom; provided, however, that nothing contained herein shall be taken
to prevent recourse to, and enforcement against, the assets of the Issuer for any and all liabilities, obligations and undertakings contained in the Indenture or in this Class A(2012-A) Note.
