 [REVERSE OF NOTE] 

This Note is one of the Notes of a duly authorized issue of Notes of the Issuer, designated as its [Floating Rate] [    %]
[Discount] Class B(    -    ) DiscoverSeries Notes (herein called the “Class B(    -    ) Notes”),
all issued under an Amended and Restated Indenture dated as of December 22, 2015 (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 a Second Amended and Restated Indenture Supplement for the DiscoverSeries Notes, dated as of December 22, 2015 (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(    -    ) Notes are subject to all terms of the
Indenture, the Indenture Supplement and the Terms Document. All terms used in this Class B(    -    ) 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(    -    ) 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(    -    ) 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 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.
Principal of the Class B(    -    ) Notes will be payable on the Expected Maturity Date in an amount described on the face hereof except as otherwise provided in the Indenture or the Indenture Supplement.

 As described above, the entire unpaid principal amount of this Class B(    -    ) Note shall
be due and payable on the Legal Maturity Date. Notwithstanding the foregoing, the entire unpaid principal amount of the Class B(    -    ) Notes shall be due and payable on the date on which an Event of
Default relating to the Class B(    -    ) 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(    -    ) 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 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 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(    -    )
Notes of record on the related Record Date (except for the final distribution with respect to this Class B(    -    ) Note) such Holder’s pro rata share of the amounts held by the Paying Agent that
are allocated and available on such Payment Date to pay interest and principal on the Class B Notes. 
 Payments of [interest on this
Class B(    -    ) 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(    -    ) Note, shall be made by check mailed to the Person whose name appears as the Registered Holder of this Class B(    -    ) Note on the Note
Register as of the close of business on each Record Date, except that with respect to Class B(    -    ) Notes registered on the Record Date in the name of the nominee of the clearing agency (initially,
such nominee to be CEDE & CO.), 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(    -    ) Note be submitted for notation of payment. Any reduction in the principal amount of this
Class B(    -    ) 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(    -    ) Note and of any Class B(     -    ) 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(    -    ) 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(    -    ) 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(    -    ) Note may be registered on the Note Register upon surrender of this
Class B(    -    ) 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(    -    ) 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(    -    ) 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 B (    -    ) Note or, in the case of a Note Owner, a beneficial interest in a Class B(    -    ) Note, covenants and agrees
that by accepting the benefits of the Indenture 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. 

By acquiring a Class B(    -    ) Note (or interest therein), each Noteholder or Note Owner (and
if each Noteholder or Note Owner is a Plan, its fiduciary) shall be deemed to represent and warrant that either: (a) it is not acquiring the Class B(    -    ) Note (or interest therein) with the
assets of (i) an “employee benefit plan” as defined in Section 3(3) of Employee Retirement Income Security Act of 1974 (“ERISA”) that is subject to Title I of ERISA, (ii) a “plan” as defined in and
subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”) (iii) an entity deemed to hold plan assets of the foregoing (each of (i), (ii) and (iii), a “Benefit Plan Investor”) or
(iv) a plan that is subject to federal, state, local or other law that is similar to the fiduciary or prohibited transaction provisions of ERISA or Section 4975 of the Code (“Similar Law”); or (b) the acquisition and
holding of the Class B(    -    ) Note (or interest therein) will not give rise to a nonexempt prohibited transaction under ERISA or Section 4975 of the Code or a violation of any Similar Law. 

Prior to the due presentment for registration of transfer of this Class B(    -    ) 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(    -    ) 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(    -    ) 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 662/3% 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(    -    ) Note shall be conclusive and binding upon such Holder and upon all future Holders of this Class B(    -    ) 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(    -    ) 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(    -    ) 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(    -    ) Notes are issuable only in registered form in denominations as provided in the Indenture, subject to certain limitations therein set forth. 

THIS CLASS B    -    ) 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(    -    ) 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(    -    ) 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(    -    ) 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(    -    ) Note.
