any Due Period shall be determined on a straight-line basis and shall be equal to the product of (x) a fraction the numerator of which shall be the number of Due Periods elapsed since the Note Issuance Date (or if additional Class C(2017-2)
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 C(2017-2) 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

preceding the first Due Period in the scheduled 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 

  
 14 








 
Principal Amounts, the delay in the commencement of the Accumulation Period for the Class C(2017-2) 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 provide written notice to each applicable Note Rating Agency in the event that the commencement of the Accumulation Period for the
Class C(2017-2) Notes is delayed pursuant to this Section 2.13. 
 Section 2.14. Duties of the Indenture Trustee.
For the avoidance of doubt, the Indenture Trustee undertakes to perform only such duties as are specifically set forth in the Indenture, the Indenture Supplement, the Pooling and Servicing Agreement, any Series Supplement and this Agreement and as
such shall have no obligation or responsibility to monitor or enforce compliance with Regulation RR, nor shall be liable to any Person for any violation of Regulation RR; provided that nothing in this Section 2.14 shall alter the Indenture
Trustee’s duties, obligations or standard of care as set forth in the Indenture or any Indenture Supplement. It is understood and acknowledged that the Indenture Trustee has not provided any advice with respect to the acquisition of the Class
C(2017-2) Notes, and has no financial interest in the acquisition of such Class C(2017-2) Notes.

 REVERSE OF NOTE 

This Note is one of the Notes of a duly authorized issue of Notes of the Issuer, designated as its Class C(2017-2) DiscoverSeries Notes
(herein called the “Class C(2017-2) 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 C(2017-2) Notes are subject to all terms of
the Indenture, the Indenture Supplement and the Terms Document. All terms used in this Class C(2017-2) 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(2017-2) 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(2017-2) 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(2017-2) 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(2017-2) 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 Stated Principal
Amount of this Class C(2017-2) 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(2017-2) Notes shall be due and payable on the date on which
an Event of Default relating to the Class C(2017-2) 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(2017-2) 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(2017-2) Notes of record on the related Record Date
(except for the final distribution with respect to the Class C(2017-2) Notes) the pro rata share for such Holder of Class C(2017-2) 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(2017-2) 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(2017-2) Note, shall be made by check mailed to the Person whose name appears as the Registered Holder of this Class C(2017-2) Note on the Note Register as of the close of business on each Record Date,
except that with respect to Class C(2017-2) 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(2017-2) Note be submitted for notation of payment. Any
reduction in the principal amount of this Class C(2017-2) 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(2017-2) Note and of any Class
C(2017-2) 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(2017-2) 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(2017-2) 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.

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

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(2017-2) Note shall be conclusive and binding upon such Holder and upon all future Holders of this Class C(2017-2) 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(2017-2) 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.
