Section 2.01. Creation and Designation.

29

(a) Under the Original Indenture Supplement, there was created a Series of Notes issued pursuant to the Indenture and the Original Indenture Supplement to be known as “Discover Card Execution Note Trust, DiscoverSeries” or the “DiscoverSeries Notes.” The DiscoverSeries Notes were issued in four Classes, the first of which is known as the “Class A Notes,” the second of which is known as the “Class B Notes,” the third of which is known as the “Class C Notes” and the fourth of which is known as the “Class D Notes.” The DiscoverSeries Notes are hereby continued under the Indenture and this Indenture Supplement, and shall continue to be issued in four Classes with the same designations as specified above in this Section 2.01(a).

(b) The DiscoverSeries Notes shall not be subordinated to any other Series of Notes.

(c) Notwithstanding the allocation provisions of the Indenture, this Indenture Supplement and the Indenture Supplements for each other Series of Notes, if any, to the extent that the DiscoverSeries Noteholders are deemed to have any interest in any assets of the Issuer allocated to other Series of Notes secured by the Collateral, the DiscoverSeries Noteholders agree by acceptance of their DiscoverSeries Notes that their interest in those assets is subordinate to claims or rights of the Noteholders of such other Series of Notes to those other assets. Further, the DiscoverSeries Noteholders shall agree by their acceptance of their DiscoverSeries Notes that such agreement constitutes a subordination agreement for purposes of Section 510(a) of the Bankruptcy Code.

Section 2.02. New Issuances of Notes. The Issuer may issue new Tranches of Notes (including additional Notes of an Outstanding Tranche) to be included in the DiscoverSeries, so long as the following conditions precedent are satisfied:

(i) on or before the date that the new issuance is to occur, the Issuer shall have delivered to the Indenture Trustee a Terms Document relating to the applicable Tranche of Notes;

(ii) with respect to an issuance of Class A Notes, immediately after giving effect to such issuance, the Nominal Liquidation Amount of the Class B Notes must be at least equal to the Class A Available Subordinated Amount of Class B Notes for all Tranches of Class A Notes;

(iii) with respect to an issuance of Class A Notes or Class B Notes, immediately after giving effect to such issuance, the Nominal Liquidation Amount of the Class C Notes must be at least equal to the sum of (x) the aggregate Class A Available Subordinated Amount of Class C Notes for all Tranches of Class A Notes with a Required Subordinated Amount of Class B Notes equal to zero and (y) the aggregate Class B Available Subordinated Amount of Class C Notes for all Tranches of Class B Notes;

(iv) with respect to an issuance of Class A Notes, Class B Notes or Class C Notes, immediately after giving effect to such issuance, the Nominal Liquidation Amount of the Class D Notes must be at least equal to the aggregate Class C Available Subordinated Amount of Class D Notes for all Tranches of Class C Notes;

30

(v) the Issuer shall be entitled to cause an increase in the Series Investor Interest for the Series 2007-CC Collateral Certificate or any Additional Collateral Certificate by an amount equal to the Nominal Liquidation Amount for such Notes as specified in the related Terms Document and all conditions to such increase, including without limitation any conditions relating to the Minimum Principal Receivables Balance of DCMT or any comparable provision of any other applicable Master Trust, shall have been satisfied;

(vi) the conditions specified in Section 310 of the Indenture are satisfied (unless such issuance does not exceed the De Minimis Threshold, in which case only such conditions specified in Section 310 of the Indenture as the applicable Note Rating Agencies shall require shall be satisfied); provided that the requirement in Section 310(a)(iv) to deliver an Opinion of Counsel of the type specified in clause (d) of the definition of “Issuer Tax Opinion” need not be satisfied if the new Tranche of Notes (or the additional Notes of an Outstanding Tranche) is being issued only to a Person or Persons considered the same Person as the single beneficial owner of the Issuer for U.S. federal income tax purposes; provided, further that, for the avoidance of doubt, any one of the conditions specified in Section 310(a) of the Indenture may be eliminated or modified as a condition precedent to any new issuance of a Tranche of Notes as permitted by Section 310(a) of the Indenture; and

(vii) any other conditions specified in the related Terms Document.

Section 2.03. Cash Deposit in Class C Reserve Account and Class D Reserve Account. If the issuance of Notes pursuant to Section 2.02 is expected to result in an increase in the Targeted Cumulative Class C Reserve Deposit for any Tranche of Class C Notes or the Targeted Cumulative Class D Reserve Deposit for any Tranche of Class D Notes, immediately after receipt of the proceeds of the Notes issued pursuant to Section 2.02, the Issuer shall deposit an amount equal to such increase into each applicable Class C Reserve Subaccount or Class D Reserve Subaccount from the proceeds of such Notes.

All Series Finance Charge Amounts and Series Principal Amounts allocated to the DiscoverSeries pursuant to the Indenture or designated in any applicable Terms Document and received by the Note Issuance Trust in accordance with such Terms Document or any related agreement shall be deposited into the DiscoverSeries Collections Account; provided, however, that the Calculation Agent may direct each Master Trust Trustee to retain any funds in Master Trust accounts that will be allocated to Master Trust accounts or paid to each Master Servicer in

31

accordance with these Cash Flows, and any such amounts shall not be deposited into the DiscoverSeries Collections Account; and provided, further, that any such amounts shall nonetheless be treated as Series Finance Charge Amounts and Series Principal Amounts hereunder and allocated as if they had been so deposited.

(2) Withdrawal of Income on Accounts. An amount equal to income earned on all funds on deposit in the Principal Funding Account, the Interest Funding Account and the Accumulation Reserve Account (including all Subaccounts of such accounts) (net of investment expenses and losses) for the period from and including the prior Distribution Date to but excluding the current Distribution Date shall be withdrawn from each such account, deposited into the DiscoverSeries Collections Account, and treated as Series Finance Charge Amounts.

(3) Withdrawal from Accumulation Reserve Subaccounts to Cover Accumulation Negative Spread on Principal Funding Subaccounts. An amount equal to the Accumulation Negative Spread for any Principal Funding Subaccount for any Tranche of Notes in the Accumulation Period for such Tranche shall be withdrawn from the Accumulation Reserve Subaccount for such Tranche, deposited into the DiscoverSeries Collections Account and treated as Series Finance Charge Amounts.

(4) Class A Interest Allocation from Series Finance Charge Amounts. An amount equal to the lesser of

shall be deposited into the Interest Funding Account. The amount by which the Class A Interest Allocation exceeds the amount of such deposit shall be the “Class A Interest Allocation Shortfall.” The Series Finance Charge Amounts shall be reduced by the amount of such deposit. The amount deposited into the Interest Funding Account pursuant to this step (4) shall be allocated to each Tranche of Class A Notes pro rata based on the ratio of the Class A Tranche Interest Allocation to the Class A Interest Allocation and deposited into the applicable Interest Funding Subaccount for such Tranche.

EARLY REDEMPTION EVENTS AND OTHER PROVISIONS RELATING TO

SPECIAL ALLOCATIONS OF PRINCIPAL

Section 4.01. Early Redemption Events.

(a) In addition to the events identified as Early Redemption Events in Section 1201 of the Indenture, each of the following events will be an “Early Redemption Event” with respect to the DiscoverSeries Notes:

(i) if for any Distribution Date, (x) the average of the Excess Spread Amounts for the three consecutive Distribution Dates ending on and including such Distribution Date is less than the Required Excess Spread Amount for such Distribution Dates, (y) for so long as the Series 2007-CC Collateral Certificate is the only Collateral Certificate owned by the Issuer, the three month rolling average Group Excess Spread is less than zero and (z) for so long as the Series

110

2007-CC Collateral Certificate is the only Collateral Certificate owned by the Issuer and any series issued by DCMT is outstanding that is not designated as an Interchange Series in accordance with the DCMT Pooling and Servicing Agreement and the series supplement for such series, the three month rolling average Interchange Subgroup Excess Spread is less than zero (as each such term is defined in the Series 2007-CC Supplement) (such event, an “Excess Spread Early Redemption Event”);

(ii) if any Amortization Event with respect to the Series 2007-CC Collateral Certificate has occurred;

(iii) if any Trust Portfolio Repurchase Event has occurred with respect to DCMT and Discover Funding LLC is required to repurchase Principal Receivables (as defined in the DCMT Pooling and Servicing Agreement) as a result thereof;

(iv) if any Series Repurchase Event has occurred with respect to the Series 2007-CC Collateral Certificate and Discover Funding LLC is required to repurchase the Series 2007-CC Collateral Certificate as a result thereof; or

(v) if the applicable Note Rating Agencies so require upon the addition of any Collateral Certificate (other than the Series 2007-CC Collateral Certificate) to the Note Issuance Trust, the occurrence of an Amortization Event, Trust Portfolio Repurchase Event, Series Repurchase Event or any comparable event, however designated, with respect to any Additional Collateral Certificate.

Notwithstanding the foregoing, no event set forth in subclause (ii), (iii), (iv) or (v) shall be an Early Redemption Event if at the time of such event, the Note Issuance Trust owns one or more Additional Collateral Certificates and is able to reinvest all amounts received as a result of such event in such Additional Collateral Certificates (or, if such event occurs with respect to such Additional Collateral Certificates, the Note Issuance Trust is able to reinvest all such amounts in the Series 2007-CC Collateral Certificate or other Additional Collateral Certificates).

(b) In addition, the Terms Document for any Tranche of Notes may list additional events which are “Early Redemption Events” with respect to such Tranche.

(c) If, for any Distribution Date within three months following an Excess Spread Early Redemption Event, (x) the Excess Spread Amount multiplied by 12 as a percentage of the Nominal Liquidation Amount for all DiscoverSeries Notes is not less than 4.50%, (y) for so long as the Series 2007-CC Collateral Certificate is the only Collateral Certificate owned by the Issuer, the Group Excess Spread multiplied by 12 as a percentage of the Aggregate Investor Interest is not less than 4.50%, or (z) for so long as the Series 2007-CC Collateral Certificate is the only Collateral Certificate owned by the Issuer and any DCMT series that is not an Interchange Series is outstanding, the Interchange Subgroup Excess Spread multiplied by 12 as a percentage of the Series Investor Interests for all Interchange Series is not less than 4.50% (any event described in clause (x), (y) or (z), an “Excess Spread Early Redemption Cure”), then unless another Early Redemption Event or Event of Default has occurred (other than an Excess Spread Early Redemption Event), the early redemption of the Notes shall cease (provided that any amounts allocated to any principal funding subaccount on such Distribution Date in connection

111

with any Excess Spread Early Redemption Event occurring or in effect on the prior Distribution Date shall be paid to Noteholders notwithstanding such Excess Spread Early Redemption Cure), any amounts held with respect to the Required Daily Deposit as a result of such Excess Spread Early Redemption Event may be immediately released to the extent contemplated in the final paragraph of the definition thereof, the Targeted Principal Deposit for each Tranche shall no longer be determined pursuant to clause (c) of the definition thereof, and principal shall not be paid on any Distribution Date that was not a scheduled Principal Payment Date for such Tranche as set forth in the applicable Terms Document; provided, however, that if,

(i) for any Distribution Date within the three months immediately after such Excess Spread Early Redemption Cure has occurred, the conditions establishing the original Excess Spread Early Redemption Event continue to exist (i.e., the Excess Spread Amount, Group Excess Spread and Interchange Subgroup Excess Spread on a three-month rolling average basis each continue to be less than zero), then unless any condition set forth in any of clauses (x), (y) or (z) above is satisfied for such Distribution Date (i.e., any of the Excess Spread Amount, Group Excess Spread or Interchange Subgroup Excess Spread on a one-month basis, as applicable, multiplied by 12 and as a percentage of the Nominal Liquidation Amount for all DiscoverSeries Notes or the Aggregate Investor Interest, as applicable, is not less than 4.50%), or

(ii) for any Distribution Date within the three months immediately after such Excess Spread Early Redemption Cure has occurred, each of the Excess Spread Amount, the Group Excess Spread and the Interchange Subgroup Excess Spread, as applicable, is less than zero the early redemption of the Notes shall resume and all allocations or calculations that are required to be based on the Nominal Liquidation Amount of any Tranche immediately prior to the occurrence of an Early Redemption Event will be made as though the original Excess Spread Early Redemption Event had occurred and such Excess Spread Early Redemption Cure had not occurred. An Excess Spread Early Redemption Cure shall not be permitted within twelve months of a prior Excess Spread Early Redemption Cure.

Following an Excess Spread Early Redemption Cure, the Accumulation Amount for each Tranche of Notes shall be adjusted by the Calculation Agent to give effect to any payments made in connection with the early redemption of the Notes prior to such Excess Spread Early Redemption Cure.

Notwithstanding the foregoing, an Excess Spread Early Redemption Cure shall only occur if the Calculation Agent certifies in good faith that the Excess Spread Early Redemption Event for a Tranche of Notes has occurred as a result of the introduction of or any change in or in the interpretation or application of any law or regulation, or the imposition of any guideline or request from any central bank or other Governmental Authority (including, without limitation, any entity exercising executive, legislative, judicial, regulatory or administrative functions of or pertaining to government), accounting standards board or any comparable entity. The Issuer may change any of the percentages set forth in clauses (x), (y) or (z) (or the proviso in the first paragraph) of this clause (c) without the consent of any Noteholders at any time that any of the Excess Spread Amount, Group Excess Spread or Interchange Subgroup Excess Spread on a three-month rolling average basis, multiplied by 12 and as a percentage of the Nominal Liquidation Amount for all DiscoverSeries Notes or the Aggregate Investor Interest, as applicable, has been not less than the percentage set forth in clause (x), (y) or (z) (as adjusted in

112

accordance with this Section 4.01(c)), as applicable, for six consecutive months, if the Issuer has satisfied the Rating Agency Condition with respect to any applicable Note Rating Agency for all Tranches of Outstanding Discover Series Notes; provided, however, that, unless otherwise provided in the Terms Document for such Tranche, no such percentage may be reduced below 0.50%.

For the purposes of this Section 4.01(c), the Excess Spread Amount, the Group Excess Spread and the Interchange Subgroup Excess Spread will be determined on a pro forma basis, for which Finance Charge Amounts will be determined as though the Finance Charge Allocation Amount for each Tranche of Notes is the Nominal Liquidation Amount for such Tranche as of the first day of the related Due Period.

Section 4.02. Variable Accumulation Period. Unless otherwise provided in the Terms Document for any Tranche of Notes, the Calculation Agent on behalf of the Issuer shall, by written notice to the Indenture Trustee, delay the commencement of the Accumulation Period for any Tranche of Notes and determine a new Accumulation Commencement Date, subject to the conditions set forth in this Section 4.02; 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 such Tranche. 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 4.02).

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 is able to deliver 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 any Tranche of Notes of the DiscoverSeries will not result in any Tranche of Notes not being paid in full on the relevant Expected Maturity Date (and the Calculation Agent shall deliver such certificate); (ii) such delay is permitted under the Series 2007-CC Series Supplement or any other applicable agreement relating to any Additional Collateral Certificate; (iii) the Rating Agency Condition shall be satisfied for all Tranches of Outstanding DiscoverSeries Notes; and (iv) the Accumulation Amount, the Accumulation Commencement Date and the Accumulation Period Length shall have been adjusted.

Section 4.03. Calculation of Targeted Prefunding Deposit. On any Distribution Date on which the Targeted Principal Deposit for any Tranche of Class B Notes, Class C Notes or Class D Notes is greater than zero, if any Required Subordinated Amount Shortfall is greater than zero (determined after giving effect to Section 4.04(a),) the Calculation Agent shall determine each Tranche for which the Indenture Trustee, subject to the Cash Flows set forth in Section 3.01, shall make a Targeted Prefunding Deposit for such Distribution Date and the amount of such Targeted Prefunding Deposit in the following manner. For the purpose of this Section 4.03, the “Required Subordinated Amount Shortfall” of a Subordinated Class of Notes for a Senior Class of Notes means the aggregate Required Subordinated Amount of the Subordinated Class of Notes for all Tranches of the Senior Class of Notes minus the aggregate Nominal Liquidation

113

Amount of all Tranches of the Subordinated Class of Notes, in each case after giving effect to all Targeted Principal Deposits for all Tranches of Notes for such Distribution Date (whether or not such Targeted Principal Deposits are paid on such Distribution Date in accordance with the Cash Flows set forth in Section 3.01). Following each determination of a Targeted Prefunding Deposit for any Tranche of Notes, the Calculation Agent shall redetermine each Required Subordinated Amount Shortfall after giving effect to such deposit, and shall continue to determine Tranches for which the Indenture Trustee, subject to the Cash Flows set forth in Section 3.01, shall make a Targeted Prefunding Deposit until all Required Subordinated Amount Shortfalls have been reduced to zero.

(a)   Determination of Prefunding Class.

is greater than zero, the “Prefunding Class” will be Class B.

(b)   Determination of Determinant Class.

(x) the Required Subordinated Amount Shortfall of Class B Notes for Class A Notes, the “Determinant Class” is Class B;

114

(y) the Required Subordinated Amount Shortfall of Class C Notes for Class A Notes, the “Determinant Class” is Class C; and

(z) the Required Subordinated Amount Shortfall of Class D Notes for Class A Notes, the “Determinant Class” is Class D.

(c)   Determination of Prefunding Tranche.

Among all Tranches of the Prefunding Class, the “Prefunding Tranche” is, if only one Tranche has the largest Required Subordinated Percentage of the Determinant Class of Notes, such Tranche, and if more than one Tranche shares the largest Required Subordinated Percentage of the Determinant Class of Notes, each such Tranche.

(d)   Determination of Targeted Prefunding Deposit.

The Calculation Agent will determine the following amounts:

and

The “Targeted Prefunding Deposit” for each Prefunding Tranche of the Prefunding Class will be the lesser of the amount determined in clause (d)(i) and the amount determined in clause (d)(ii) above multiplied by a fraction, the numerator of which is the Nominal Liquidation Amount of such Prefunding Tranche and the denominator of which is the Nominal Liquidation Amount of all Prefunding Tranches, in each case remaining after step (59) of the Cash Flows (Withdrawal of Prefunding Excess Amounts for use as Series Principal Amounts).

Section 4.04. Calculation of Prefunding Excess Amounts.

115

(a) On each Distribution Date, amounts on deposit in the applicable Principal Funding Subaccount that had been previously deposited as part of any Targeted Prefunding Deposit for such Tranche, up to, (a) for any Tranche that does not have an Accumulation Period, for any Distribution Date that is a Principal Payment Date for such Tranche, the amount scheduled to be paid on such Principal Payment Date as specified in the related Terms Document, plus any Targeted Principal Deposit that was scheduled to be paid on any previous Principal Payment Date that was not so paid, (b) for any Tranche in its Accumulation Period, the Accumulation Amount for such Tranche, plus any Accumulation Amount that was scheduled to be deposited on any previous Distribution Date in the Accumulation Period that was not so deposited, and (c) for any Tranche that has a Performing or non-Performing Derivative Agreement for principal that provides for a payment to the applicable Derivative Counterparty, the amount specified in the related Terms Document as the amount to be deposited on the applicable Distribution Date with respect to any payment to the Derivative Counterparty, plus any amount that was scheduled to be deposited on any previous Distribution Date that was not so deposited, shall be treated as having been applied in satisfaction of such deposit or payment and shall no longer be considered Targeted Prefunding Deposits for purposes of this Section 4.04 or any other provision of this Indenture Supplement.

(b) On each Distribution Date, if any amounts deposited with respect to any Targeted Prefunding Deposit remain on deposit with respect to any Tranche of Notes after giving effect to clause (a) above, the Calculation Agent shall make a pro forma determination of the Adjusted Outstanding Dollar Principal Amount of each such Tranche after adding thereto such amounts on deposit, and shall determine the Targeted Prefunding Deposit for each Tranche of Notes in accordance with the methodology set forth in Section 4.03 above after giving effect to such pro forma determination. The “Prefunding Excess Amount” for each Tranche of Notes is the positive difference, if any, between the amount of funds on deposit in the Principal Funding Subaccount for such Tranche that the Indenture Trustee has previously deposited in connection with a Targeted Prefunding Deposit (less any amounts recharacterized under clause (a)) and the amount determined for each such Tranche as the Targeted Prefunding Deposit in accordance with such pro forma calculation. For the avoidance of doubt, if the Required Subordinated Amount Shortfall of any Subordinated Class of Notes for any Senior Class of Notes is zero after giving effect to such pro forma determination of the Adjusted Outstanding Dollar Principal Amounts of each such Tranche, all funds on deposit in the Principal Funding Subaccount for each Tranche belonging to such Senior Class that the Indenture Trustee has previously deposited in connection with a Targeted Prefunding Deposit (less any amounts recharacterized under clause (a)) shall be considered Prefunding Excess Amounts and shall be withdrawn from each applicable Principal Funding Subaccount in accordance with Section 3.05(4).

Section 4.05. Receivables Sale.

(a) (i) If a Tranche of Notes has been accelerated pursuant to Section 702 of the Indenture following an Event of Default, the Indenture Trustee may, and at the direction of the Majority Holders of that Tranche of Notes will, notify each Master Trust Trustee to sell an amount of Receivables (as defined in the applicable Pooling and Servicing Agreement or as comparably defined in any other applicable agreement relating to any Additional Collateral Certificate) equal to

116

(ii) The Indenture Trustee will cause each Master Trust Trustee to sell Receivables pursuant to clause (a)(i) above only if at least one of the following conditions is met:

(iii) In the case of an acceleration of a Tranche of a Subordinated Class, unless the Targeted Prefunding Deposits for all Tranches of Senior Class on the following Distribution Date are zero, such sale will be delayed until a level of prefunding of the Principal Funding Subaccounts for the Senior Classes of Notes of that Series has been reached such that the amount of such accelerated Tranche is no longer required to provide subordination for the Senior Classes of Notes.

117

(iv) Notwithstanding any other provision herein or in the Series 2007-CC Supplement, the Indenture Trustee shall not cause any Master Trust Trustee to sell Receivables to CONA and any of its Affiliates.

(b) If the Nominal Liquidation Amount with respect to any Tranche of Notes is greater than zero on its Legal Maturity Date (after giving effect to any adjustments, deposits and distributions otherwise to be made on that Legal Maturity Date), the Indenture Trustee shall notify each Master Trust Trustee to sell an amount of Receivables equal to the amount of clause (a)(x) multiplied by the percentage of clause (a)(y) pursuant to Section 12(b) of the Series 2007-CC Supplement or any comparable provision in any such other agreement, in each case to the extent provided in the Indenture.

Section 5.01. Issuer Accounts.

(a) On or before the Effective Date, the Indenture Trustee will cause to be established and maintained six Eligible Deposit Accounts denominated as follows: the “DiscoverSeries Collections Account,” the “Interest Funding Account,” the “Principal Funding Account,” the “Accumulation Reserve Account,” the “Class C Reserve Account” and the “Class D Reserve Account” in the name of the Indenture Trustee, bearing a designation clearly indicating that the funds deposited therein are held for the benefit of the Series Noteholders (or, in the case of the Class C Reserve Account, for the benefit of the Class C Noteholders or, in the case of the Class D Reserve Account, for the benefit of the Class D Noteholders). The DiscoverSeries Collections Account, the Interest Funding Account, the Principal Funding Account, the Accumulation Reserve Account, the Class C Reserve Account and the Class D Reserve Account constitute Issuer Accounts, shall be maintained in accordance with Article IV of the Indenture , and shall be under the sole dominion and control of the Indenture Trustee for the benefit of the Series Noteholders (or, in the case of the Class C Reserve Account, for the benefit of the Class C Noteholders or, in the case of the Class D Reserve Account, for the benefit of the Class D Noteholders). If, at any time, the institution holding any of the DiscoverSeries Collections Account, the Interest Funding Account, the Principal Funding Account, the Accumulation Reserve Account, the Class C Reserve Account or the Class D Reserve Account ceases to be an Eligible Institution, the Issuer will within ten (10) Business Days (or such longer period, not to exceed thirty (30) calendar days, as to which the applicable Note Rating Agencies may consent) establish a new DiscoverSeries Collections Account, Interest Funding Account, Principal Funding Account, Accumulation Reserve Account, Class C Reserve Account or Class D Reserve Account, as the case may be, that is an Eligible Deposit Account and shall transfer any cash and other property to such new DiscoverSeries Collections Account, Interest Funding Account, Principal Funding Account, Accumulation Reserve Account, Class C Reserve Account or Class D Reserve Account, as the case may be. From the date such new DiscoverSeries Collections Account, Interest Funding Account, Principal Funding Account, Accumulation Reserve Account, Class C Reserve Account or Class D Reserve Account is established, it will be the “DiscoverSeries Collections Account,” the “Interest Funding Account,” the “Principal Funding Account,” the “Accumulation Reserve Account,” the “Class C Reserve Account” or the “Class D

118

Reserve Account,” as the case may be. Each Tranche of Notes will have its own Subaccount within the Interest Funding Account, the Principal Funding Account and the Accumulation Reserve Account; each Tranche of Class C Notes will have its own Subaccount within the Class C Reserve Account, if applicable; and each Tranche of Class D Notes will have its own Subaccount within the Class D Reserve Account, if applicable. The DiscoverSeries Collections Account, the Interest Funding Account, the Principal Funding Account, the Accumulation Reserve Account, the Class C Reserve Account and the Class D Reserve Account will receive deposits pursuant to Article III.

(b) Notwithstanding any provision of Section 403(a) of the Indenture to the contrary, any prefunded amounts on deposit in the Principal Funding Account will be invested in Permitted Investments that will mature no later than the following Distribution Date.

(c) All payments to be made from time to time by the Indenture Trustee to Noteholders out of funds in the Interest Funding Account or the Principal Funding Account pursuant to this Indenture Supplement will be made by the Indenture Trustee to the Paying Agent not later than the time required by the applicable Depository on the applicable Interest Payment Date or Principal Payment Date but only to the extent of funds on deposit in the applicable Subaccount or as otherwise provided in Article III.

(d) On each Distribution Date, all interest and earnings (net of losses and investment expenses) accrued since the preceding Distribution Date on funds on deposit in the Class C Reserve Account will be retained in the Class C Reserve Account (to the extent that the sum of the amount on deposit in the Class C Reserve Account with respect to the related Due Period is less than the required balance for the Class C Reserve Account for that Due Period) and the excess, if any, will be paid to the Issuer pursuant to step (51) (Withdrawal of Excess Deposits from Class C Reserve Subaccounts for use as Series Finance Charge Amounts) of Section 3.01.
