make such additional amendments to this Terms Document as shall be necessary for such replacement without the consent of any Noteholders, provided that the Issuer has received written confirmation from each applicable Note Rating Agency that

 (B) the Note Interest Rate in effect with respect to such related
Interest Accrual Period, times 
  

	 	(ii)	 the Outstanding Dollar Principal Amount of the Class C(2020-4)
Notes determined as of the first date of such related Interest Accrual Period, plus 



  
 10 













 any Class C Tranche Interest Allocation Shortfall for such

notification of LIBOR for the following Interest Accrual Period. U.S. Bank National Association is appointed hereunder not in its individual capacity, but solely with respect to calculating the amount of interest to be paid with respect to the
Notes, including calculating LIBOR, in the manner and at the times provided herein as LIBOR Agent, and U.S. Bank National Association hereby accepts such appointment. The rights, protections and immunities granted to the Indenture Trustee under the

its own negligence, willful misconduct or fraud. 
 The LIBOR Agent shall not have any liability for (i) the selection of London banks
or New York banks whose quotations may be requested and used for purposes of calculating LIBOR, or for the failure or unwillingness of any London banks or New York banks to provide a quotation, or (ii) any quotations received from such London
banks or New York banks, as applicable. For the avoidance of doubt, if the rate appearing on the Reuters Screen LIBOR01 is unavailable, neither the LIBOR Agent nor the Indenture Trustee shall be under any duty or obligation to take any action other
than the LIBOR Agent’s obligation to take the actions expressly set forth in this Agreement. Neither the Indenture Trustee nor the LIBOR Agent shall have any liability for any interest rate published by any publication that is the source for
determining the interest rates of the Class C(2020-4) Notes, including but not limited to the Reuters Screen LIBOR01 (or any successor source), or for any rates compiled by the ICE Benchmark
Administration or any successor thereto, or for any rates published on any publicly available source, including without limitation the Federal Reserve Bank of New York’s Website, or in any of the foregoing cases for any delay, error or
inaccuracy in the publication of any such rates, or for any subsequent correction or adjustment thereto. 
 Other than as expressly set
forth in this Agreement, neither the Indenture Trustee nor the LIBOR Agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of LIBOR (or other applicable benchmark), or whether or when there has
occurred, or to give notice to any other transaction party of the occurrence of, any benchmark transition event or benchmark replacement date, (ii) to select, determine or designate any alternative replacement rate to LIBOR or any other
benchmark replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate have been satisfied, (iii) to select, determine or designate any benchmark replacement adjustment, or other
modifier to any replacement or successor index, or (iv) to determine whether or what benchmark replacement conforming changes are necessary or advisable, if any, in connection with any of the foregoing. 

  
 11 













 Neither the Indenture Trustee nor the LIBOR Agent shall be liable for any inability, failure
or delay on its part to perform any of its duties set forth in this Agreement as a result of the unavailability of LIBOR (or other applicable benchmark) and absence of a designated replacement benchmark, including as a result of any inability,
delay, error or inaccuracy on the part of any other transaction party, including without limitation the Issuer or the Calculation Agent, in providing any direction, instruction, notice or information required or contemplated by the terms of this
Agreement and reasonably required for the performance of such duties. 
 Section 2.05. Payments of Interest and Principal.
(a) The Issuer will cause interest to be paid on each Interest Payment Date and principal to be paid on the Expected Maturity Date; provided, however, that it shall not be an Event of Default if principal is not paid in full on such Expected
Maturity Date unless funds for such payment have been allocated in accordance with Section 3.01 of the Indenture Supplement; and provided, further, that if a Class C(2020-4) Adverse Event has
occurred and is continuing, principal will instead be payable in monthly installments on each Principal Payment Date for the Class C(2020-4) Notes in accordance with Sections 3.01 and 3.05 of the
Indenture Supplement. All payments of interest and principal on the Class C(2020-4) Notes shall be made as set forth in Section 1102 of the Indenture.

This Note is one of the Notes of a duly authorized issue of Notes of the Issuer, designated as its

Indenture, dated as of December 22, 2015, as amended by Amendment No. 1 to Master Indenture and Amendment No. 1 to Indenture Supplement, dated as of August 27, 2019 (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, as amended by Amendment No. 1 to Master Indenture and Amendment No. 1 to Indenture Supplement, dated as of August 27, 2019 (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 C(2020-4) Notes are subject to all terms of the Indenture, the
Indenture Supplement and the Terms Document. All terms used in this Class C(2020-4) 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 B Notes
and the Class D Notes of the DiscoverSeries and other tranches of Class C Notes of the DiscoverSeries will also be issued under the Indenture and the Indenture Supplement. 

The Class C(2020-4) 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 C(2020-4) Notes are subordinated in right of payment of principal and interest to the Class A Notes and the Class B Notes and provide loss protection to the Class A Notes and the
Class B Notes of the DiscoverSeries, to the extent set forth in the Indenture Supplement. Principal Amounts allocable to the Class C(2020-4) Notes may be applied to pay the Class A Interest
Allocation and the Class B 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 C(2020-4) Notes will be payable on the Expected Maturity

 As described
above, the entire unpaid Stated Principal Amount of this Class C(2020-4) Note shall be due and payable on the Legal Maturity Date. Notwithstanding the foregoing, the entire unpaid Outstanding Dollar
Principal Amount of the Class C(2020-4) Notes shall be due and payable on the date on which an Event of Default relating to the Class C(2020-4) 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 C(2020-4) 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. 

  
 Ex. A-7 













 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 C(2020-4) Notes
of record on the related Record Date (except for the final distribution with respect to the Class C(2020-4) Notes) the pro rata share for such Holder of
Class C(2020-4) 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 C Notes. 
 Payments of interest on this Class C(2020-4) 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 C(2020-4) Note, shall be made by check mailed to the Person whose name appears as the Registered Holder of this Class C(2020-4) Note on the Note Register
as of the close of business on each Record Date, except that with respect to Class C(2020-4) 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 C(2020-4) Note be submitted for notation of payment. Any reduction in the principal amount of this Class C(2020-4) 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 C(2020-4) Note and of any
Class C(2020-4) 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 C(2020-4) 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 C(2020-4) 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. 

  
 Ex. A-8 













 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 C(2020-4) Note may be registered on the Note Register upon surrender of this
Class C(2020-4) 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 C(2020-4) 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 C(2020-4) 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 C(2020-4) Note or, in the case of a Note Owner, a beneficial interest in a Class C(2020-4) 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. 

Prior to the due presentment for registration of transfer of this Class C(2020-4) 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 C(2020-4) 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 C(2020-4) 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 C(2020-4) Note shall be conclusive and binding upon such Holder and upon all future Holders of this Class C(2020-4) 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 C(2020-4) 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.

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
