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(2015-1) 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 

  
 15 








 
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 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(2015-1) Notes is delayed pursuant to this Section 2.13.

 REVERSE OF NOTE 

This Note is one of the Notes of a duly authorized issue of Notes of the Issuer, designated as its Class B(2015-1) DiscoverSeries Notes
(herein called the “Class B(2015-1) 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(2015-1) Notes are subject to all terms of the Indenture, the Indenture Supplement and the Terms Document. All terms used in this Class B(2015-1) 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(2015-1) 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(2015-1) 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(2015-1) Notes may be applied to pay the Class A
Interest Allocation or the Series Servicing Fees of the DiscoverSeries, to the extent set forth in the Indenture Supplement. 
 The Stated
Principal Amount of the Class B(2015-1) 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(2015-1) 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(2015-1)
Notes shall be due and payable on the date on which an Event of Default relating to the Class B(2015-1) 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(2015-1) 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. 
 On any day
occurring on or after the date on which the aggregate Nominal Liquidation Amount of any Tranche of Notes is reduced to less than 5% of its highest Outstanding Dollar Principal Amount, the Depositor or any Affiliate thereof has the right, but not the
obligation, to redeem such Tranche of Notes in whole but not in part, pursuant to Section 1202 of 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(2015-1) Notes of record on the related Record
Date (except for the final distribution with respect to the Class B(2015-1) Notes) the pro rata share for such Holder of Class B(2015-1) 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(2015-1) 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(2015-1) Note, shall be made by check mailed to the Person whose name appears as the Registered Holder of this Class B(2015-1) Note on the Note Register as of the close of business on each Record Date,
except that with respect to Class B(2015-1) 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(2015-1) Note be submitted for notation of payment. Any
reduction in the principal amount of this Class B(2015-1) 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(2015-1) Note and of any Class B(2015-1)
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(2015-1) 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(2015-1) 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. 







 As provided in the Indenture and subject to certain limitations set forth therein and as set
forth in the first legend on the face hereof, the transfer of this Class B(2015-1) Note may be registered on the Note Register upon surrender of this Class B(2015-1) Note for registration of transfer at the office or agency designated by the Issuer
pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by, the Holder hereof or his attorney duly authorized in writing, with such signature
guaranteed by a commercial bank or trust company located, or having a correspondent located, in the City of New York or the city in which the Corporate Trust Office is located, or a member firm of a national securities exchange, and such other
documents as the Indenture Trustee may require, and thereupon one or more new Class B(2015-1) Notes of authorized denominations and in the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge

registration of transfer or exchange. 
 To the fullest extent permitted by applicable law, each Noteholder or Note Owner, by acceptance of
a Class B(2015-1) Note or, in the case of a Note Owner, a beneficial interest in a Class B(2015-1) 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(2015-1) 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(2015-1) 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 B(2015-1) Note be overdue, and neither the Issuer, the Indenture Trustee nor any such agent
shall be affected by notice to the contrary. 
 The Indenture permits, with certain exceptions as therein provided, the 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(2015-1) Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Class B(2015-1) 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(2015-1) 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(2015-1) Note includes any successor to the Issuer under the Indenture. 

The Issuer is permitted by the Indenture, under certain circumstances, to merge or consolidate, subject to the rights of the Indenture Trustee
and the Holders of Notes under the Indenture. 
 The Class B(2015-1) Notes are issuable only in registered form in denominations as provided
in the Indenture, subject to certain limitations therein set forth. 
 THIS CLASS B(2015-1) 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(2015-1) 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(2015-1) 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(2015-1) 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(2015-1) Note.
