B(2012-1) Notes or the effect of such issuance of additional Class B(2012-1) Notes on any calculations to be made with respect to the Class B(2012-1) Notes, Class B, or the Issuer. 


All such terms shall be incorporated into and form a part of this Terms Document on and after the effective date of such Class B(2012-1) Notes; and

 Section 2.10. Designation of Additional Amounts to be included in the Excess Spread Amount for the DiscoverSeries Notes. At any time that any outstanding Series of certificates issued by the

each outstanding Tranche of the DiscoverSeries Notes (including these notes) and 

  
 14 









 
the denominator of which is (i) the Aggregate Investor Interest for the Master Trust minus (ii) the sum of the Series Investor Interests for all such Series that provide that the
Series Principal Collections allocated to such Series will be so deposited, is hereby designated to be included in the Excess Spread Amount and shall be treated as Series Finance Charge Amounts for the DiscoverSeries. 

Section 2.11. No Payments from Interest Funding Subaccount for accretion of principal of the Class B(2012-1) Notes.
Section 3.04(4) of the Indenture Supplement shall not apply to the Class B(2012-1) Notes.

numerator of which shall be the number of Due Periods elapsed since the Note Issuance Date (or if additional Class B(2012-1) Notes have been issued under Section 2.09, since the Issuance Date of such additional Notes) and the denominator of
which shall be the number of Due Periods from the Note Issuance Date (or the Issuance Date of such additional Notes) to and including the Due Period related to the Expected Maturity Date and (y) the Discount Amount. 

Section 2.13. Variable Accumulation Period. Notwithstanding anything to the contrary in Section 4.02 of the Indenture
Supplement, the Calculation Agent on behalf of the Issuer shall, by written notice to the Indenture Trustee, delay the commencement of the Accumulation Period for the Class B(2012-1) Notes and determine a new Accumulation Commencement Date, subject
to the conditions set forth in this Section 2.13; provided, however, that the Accumulation Period shall commence no later than the first day of the Due Period related to the Expected Maturity Date for the Class B(2012-1) Notes. Any such
delay by the Calculation Agent on behalf of the Issuer shall be made no later than the first day of the scheduled Due Period immediately preceding the first Due Period in the Accumulation Period (after giving effect to any prior delay in the
commencement of the Accumulation Period pursuant to this Section 2.13). 
 The Calculation Agent on behalf of the Issuer
shall cause such delay if the Calculation Agent determines in good faith that each of the following conditions will be satisfied: (i) the Calculation Agent on behalf of the Issuer delivers to the Indenture Trustee a certificate to the effect
that the Calculation Agent on behalf of the Issuer reasonably believes that, based on the payment rate and the anticipated availability of Series Principal Amounts and Reallocated Principal Amounts, the delay in the commencement of the Accumulation
Period for the Class B(2012-1) Notes will not result in any Tranche of Notes not being paid in full on the relevant Expected Maturity Date; (ii) such delay is permitted under the Series 2007-CC Series Supplement or any other applicable
agreement relating to any Additional Collateral Certificate; and (iii) the Accumulation Amount, the Accumulation Commencement Date and the Accumulation Period Length shall have been adjusted. The Calculation Agent on behalf of the Issuer shall
not be required to obtain confirmation from the applicable Note Rating Agencies that such delay in the commencement of the Accumulation Period will not result in a Ratings Effect for any Tranche of Outstanding DiscoverSeries Notes, unless at the
time of such delay there is a Tranche of Outstanding DiscoverSeries Notes, which were issued prior to January 1, 2009 and for which the commencement of the Accumulation Period for such Tranche of Notes has already been delayed pursuant to
Section 4.02 of the Indenture Supplement. If such confirmation from 

  
 15 









 
the applicable Note Rating Agency is not required, the Calculation Agent on behalf of the Issuer shall provide written notice to each applicable Note Rating Agency in the event that the
commencement of the Accumulation Period for the Class B(2012-1) Notes is delayed pursuant to this Section 2.13.

(herein called the “Class B(2012-1) Notes”), all issued under an Indenture, dated as of July 26, 2007, as amended by the First Amendment to Indenture, dated as of June 4, 2010 (such Indenture, as may be further amended,
restated, amended and restated, supplemented, replaced or otherwise modified from time to time, is herein called the “Indenture”), as supplemented by an Amended and Restated Indenture Supplement for the DiscoverSeries Notes, dated
as of June 4, 2010, (such Indenture 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
B(2012-1) Notes are subject to all terms of the Indenture, the Indenture Supplement and the Terms Document. All terms used in this Class B(2012-1) 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 A
Notes, the Class C Notes and the Class D Notes of the DiscoverSeries and other tranches of Class B Notes of the DiscoverSeries will also be issued under the Indenture and the Indenture Supplement. 

The Class B(2012-1) 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. 
 The Class B(2012-1) Notes are subordinated in right of payment of principal and
interest to the Class A Notes and provide loss protection to the Class A Notes of the DiscoverSeries, to the extent set forth in the Indenture Supplement. Principal Amounts allocable to the Class B(2012-1) Notes may be applied to pay the

 The Stated Principal Amount of the Class B(2012-1) Notes will be payable on the Expected Maturity Date in an amount described on the face hereof. 

As described above, the entire unpaid Stated Principal Amount of this Class B(2012-1) Note shall be due and payable on the Legal Maturity
Date. Notwithstanding the foregoing, the entire unpaid Outstanding Dollar Principal Amount of the Class B(2012-1) Notes shall be due and payable on the date on which an Event of Default relating to the Class B(2012-1) Notes shall have occurred and
be continuing and, except in the event of an insolvency related default, the Indenture Trustee or the Majority Holders of the applicable Series, Class or Tranche of Outstanding Dollar Principal Amount of the Outstanding Notes have declared the Class
B(2012-1) Notes to be immediately due and payable in the manner provided in Section 702 of the Indenture; provided, however, that such acceleration of the entire unpaid Outstanding Dollar Principal Amount of the Notes may
be rescinded by the Majority Holders of such applicable Series, Class or Tranche of Notes.

the Indenture. The redemption price will be an amount equal to the Outstanding Dollar Principal Amount of such Tranche, plus accrued, unpaid and additional interest, if any, or principal accreted and unpaid on such Tranche to but excluding the date
of redemption. 
 Subject to the terms and conditions of the Indenture, the Beneficiary, on behalf of the Note Issuance Trust,
may from time to time issue, or direct the Owner Trustee, on behalf of the Note Issuance Trust, to issue, one or more Series, Classes or Tranches of Notes. 
 On each Payment Date, the Paying Agent shall distribute to each Holder of Class B(2012-1) Notes of record on the related Record Date (except for the final distribution with respect to these Class
B(2012-1) Notes) the pro rata share for such Holder of Class B(2012-1) Notes of the amounts held by the Paying Agent that are allocated and available on such Payment Date to pay interest (only if the Outstanding Dollar Principal Amount is not paid
in full on or prior to the Expected Maturity Date) and principal on the Class B Notes. 
 Payments of interest on this
Class B(2012-1) Note due and payable on each Payment Date, together with any installment of principal, if any, to the extent not in full payment of this Class B(2012-1) Note, shall be made by check mailed to the Person whose name appears as the
Registered Holder of this Class B(2012-1) Note on the Note Register as of the close of business on each Record Date, except that with respect to Class B(2012-1) Notes registered on the Record Date in the name of the nominee of a clearing agency,
payments will be made by wire transfer in immediately available funds to the account designated by such nominee. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it appears on the Note Register as of the
applicable Record Date without requiring that this Class B(2012-1) Note be submitted for notation of payment. Any reduction in the principal amount of this Class B(2012-1) 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 B(2012-1) Note and of any Class B(2012-1) 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 B(2012-1) Note on a Payment Date, then the Indenture Trustee, in the name of and on behalf of the Issuer, will
notify the Person who was the Registered Holder hereof as of the Record Date preceding such Payment Date by notice mailed within five days of such Payment Date and the amount then due and payable shall be payable only upon presentation and surrender
of this Class B(2012-1) Note at the Indenture Trustee’s principal Corporate Trust Office or at the office of the Indenture Trustee’s agent appointed for such purposes located in the City of New York. On any payment of interest or principal
being made, details of such payment shall be entered by the Indenture Trustee on behalf of the Issuer in Schedule A hereto.

may require, and thereupon one or more new Class B(2012-1) Notes of authorized denominations and in the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be charged for any
registration of transfer or exchange of this Class B(2012-1) 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

 To the fullest extent permitted by applicable law, each Noteholder or Note Owner, by acceptance of a Class
B(2012-1) Note or, in the case of a Note Owner, a beneficial interest in a Class B(2012-1) Note, covenants and agrees that by accepting the benefits of the Indenture that it will not at any time institute against the Issuer, any Master Trust or any
special purpose entity that acts as a depositor with respect to any Master Trust or the Issuer, or join in any institution against the Issuer, any Master Trust or any special purpose entity that acts as a depositor with respect to any Master Trust
or the Issuer of, any receivership, insolvency, bankruptcy or other similar proceedings, or other proceedings under any United States federal or state bankruptcy or similar law in connection with any obligations relating to the Notes, the Indenture,
any Derivative Agreement, any Supplemental Credit Enhancement Agreement and any Supplemental Liquidity Agreement. 
 Prior to
the due presentment for registration of transfer of this Class B(2012-1) 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 B(2012-1) Note (as of the day of

amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Notes under 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 B(2012-1) Note shall be conclusive and binding upon such Holder and upon all future Holders of this Class B(2012-1) 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 B(2012-1) 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 term “Issuer” as used in this Class B(2012-1) Note includes any successor to the
Issuer under the Indenture.

 The Class B(2012-1)
Notes are issuable only in registered form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 
 THIS CLASS B(2012-1) 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 B(2012-1) 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 B(2012-1) 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 B(2012-1) 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 B(2012-1) Note.
