“SECTION 2.02. Delayed Funding.

(a) Any Designated Delay Funding Purchaser (or its related Managing Agent) may, after the Transferor delivers a Notice of Incremental Funding pursuant to Section 2.03(a), deliver a written notice (a “Delayed Funding Notice”, and the date of such delivery, the “Delayed Funding Notice Date”) not later than 3:00 p.m., New York City time, on the date that is two (2) Business Days prior to the proposed Incremental Funding Date; provided that notwithstanding anything to the contrary contained in this Agreement, upon receipt of a Delayed Funding Notice, the remaining Designated Delayed Funding Purchasers (or their related Managing Agents) shall have until 12:00 p.m. New York City time on the following Business Day to deliver a Delayed Funding Notice for their respective Purchaser Groups. Each Delayed Funding Notice shall be delivered to the Transferor, with copies to the Servicer, the Administrative Agent and the Managing Agents for all other Purchaser Groups. Each Delayed Funding Notice shall indicate (A) the portion of the related Designated Delay Funding Purchaser’s share of the Incremental Funded Amount requested in such Notice of Incremental Funding which will be subject to delayed purchase (such amount, the “Designated Delayed Funding Amount”), (B) such Designated Delay Funding Purchaser’s Required Non-Delayed Funding Amount as of the proposed Incremental Funding Date and (C) if such Designated Delayed Funding Amount is greater than such Required Non-Delayed Funding Amount, specifying the portion, if any, of such excess (the “Delayed Amount” with respect to such Designated Delay Funding Purchaser and the related Incremental Funding Date) that it is electing to advance on a date (the date of such advance, the “Delayed Funding Date”) that is on or before the thirty-fifth (35th) day (or if such day is not a Business Day, then on the next succeeding Business Day) following the date of such Notice of Incremental Funding rather than on the proposed Incremental Funding Date. A Designated Delay Funding Purchaser that delivers a Delayed Funding Notice specifying a Delayed Amount with respect to any Incremental Funding Date shall be referred to herein as a “Delaying Purchaser” with respect to such Incremental Funding Date, and any Purchaser Group containing a Delaying Purchaser shall be referred to as a “Delaying Purchaser Group” with respect to such Incremental Funding Date. By delivery of a Delayed Funding Notice, a Designated Delay Funding Purchaser shall be deemed to represent and warrant that the certifications previously provided to the Transferor by such Designated Delay Funding Purchaser (or its related Managing Agent) are true as of the Delayed Funding Notice Date.

8

(b) If there are one or more Delaying Purchasers or Delaying Purchaser Groups with respect to a Incremental Funding Date, the Servicer on behalf of the Transferor may, by no later than 4:00 p.m., New York City time, on the Business Day preceding such Incremental Funding Date, request each Committed Purchaser that is not a Delaying Purchaser with respect to such Incremental Funding Date (each, a “Non-Delaying Committed Purchaser”) and each Managing Agent (on behalf of the related Purchasers) for each Purchaser Group that is not a Delaying Purchaser Group with respect to such Incremental Funding Date (each, a “Non-Delaying Purchaser Group”) to purchase an additional portion of the Incremental Funded Amount requested on such Incremental Funding Date that is equal to such Non-Delaying Committed Purchaser’s or such Non-Delaying Purchaser Group’s, as applicable, proportionate share (based upon their respective Commitments relative to the sum of the respective Commitments of all Non-Delaying Committed Purchasers and all Non-Delaying Purchaser Groups with respect to such Incremental Funding Date) of the aggregate Delayed Amounts with respect to such Incremental Funding Date (each such Non-Delaying Committed Purchaser’s or Non-Delaying Purchaser Group’s additional portion of the related Incremental Funded Amount, the “Additional Increase Amount”). Subject to the fulfillment of the conditions set forth in Section 2.03 (determined in all cases as if the Delaying Purchasers and/or Delaying Purchaser Groups with respect to such Incremental Funding Date were purchasing their respective, aggregate Delayed Amounts with respect to such Incremental Funding Date on such date), (i) in the case of a Non-Delaying Committed Purchaser, such Non-Delaying Committed Purchaser shall purchase the related Additional Increase Amount on the related Incremental Funding Date, and (ii) in the case of a Non-Delaying Purchaser Group, the Conduit Purchaser(s) in such Non-Delaying Purchaser Group may purchase the related Additional Increase Amount on the related Incremental Funding Date or, if any such Conduit Purchaser(s) fails to purchase all or any portion of the related Additional Increase Amount on the related Incremental Funding Date, each Committed Purchaser in such Non-Delaying Purchaser Group shall purchase all or the remaining portion, as applicable, of the related Additional Increase Amount on the related Incremental Funding Date, in each case, subject to and in accordance with Section 2.03.

(c) If the additional amounts required to be purchased by the Non-Delaying Committed Purchasers and the Non-Delaying Purchaser Groups under Section 2.02(b) are not sufficient to provide the aggregate amount requested by the Transferor in the related Notice of Incremental Funding, the Transferor may, at its option, elect to reduce the requested Incremental Funded Amount by that portion of the requested amount which will not be purchased by the Non-Delaying Committed Purchasers and the Non-Delaying Purchaser Groups as Additional Increase Amounts by delivery to the Delaying Purchasers, the Non-Delaying Committed Purchasers and their respective Managing Agents of an updated

9

Notice of Incremental Funding. If the Transferor reduces the requested Incremental Funded Amount by delivering an updated Notice of Incremental Funding, subject to the fulfillment of the applicable conditions set forth in Section 2.03, the Non-Delaying Committed Purchasers and the Non-Delaying Purchaser Groups shall purchase the related Additional Increase Amounts (in all cases as recalculated following the delivery of the updated Notice of Incremental Funding) in the manner set forth under Section 2.02(b) on the Business Day following the delivery of such updated Notice of Incremental Funding. If the Transferor reduces the requested Incremental Funded Amount in an updated Notice of Incremental Funding, each Delaying Purchaser with respect to the related Incremental Funding Date shall automatically have (A) its related Designated Delayed Funding Amount decreased by the same percentage that the Incremental Funded Amount is decreased between the original Notice of Incremental Funding and the updated Notice of Incremental Funding and (B) its related Delayed Amount decreased to equal the amount, if any, by which such revised Designated Delayed Funding Amount is greater than such Designated Delay Funding Purchaser’s Required Non-Delayed Funding Amount with respect to such Incremental Funding Date. If the Transferor does not elect to reduce the requested Incremental Funded Amount by an amount such that the additional amounts required to be purchased by the Non-Delaying Committed Purchasers and the Non-Delaying Purchaser Groups under Section 2.02(b) are sufficient to provide the aggregate amount requested by the Transferor in the related Notice of Incremental Funding, then the excess of the Delayed Amounts with respect to the related Incremental Funding Date over the aggregate Additional Increase Amounts with respect to the related Incremental Funding Date will be treated as Delayed Funding Shortfall Amounts that will be subject to funding by the related Delaying Committed Purchasers or Delaying Purchaser Groups, as applicable, on the related Delayed Funding Date in the manner set forth in Section 2.02(d) below.

(d) Each Delaying Committed Purchaser and each Conduit Purchaser in a Delaying Purchaser Group with respect to a Incremental Funding Date agrees by delivering a Delayed Funding Notice specifying a Delayed Amount that, (i) if the conditions to purchase the Incremental Funded Amount requested on such Incremental Funding Date described in Section 2.03 were satisfied with respect to such Incremental Funding Date there shall be no other conditions whatsoever to its obligation to fund the Delayed Funding Reimbursement Amount with respect to such Delayed Amount on the related Delayed Funding Date and (ii) if the conditions to purchase the Incremental Funded Amount requested on such Incremental Funding Date described in Section 2.03 were satisfied with respect to such Incremental Funding Date and the conditions described in Section 2.02(h) are satisfied on the related Delayed Funding Date, there shall be no other conditions whatsoever to its obligation to fund the Delayed Funding Shortfall Amount with respect to such Delayed Amount on the related Delayed Funding Date, in all cases described in clauses (i) and (ii) of this Section 2.02(d) irrespective of whether the Scheduled Purchase Expiration Date for such Committed Purchaser shall have occurred or the Commitments shall have been

10

terminated or deemed terminated prior to such Delayed Funding Date. In the case of a Delaying Purchaser Group, the Conduit Purchaser(s) in such Delaying Purchaser Group may purchase the related Additional Increase Amount on the related Delayed Funding Date or, if any such Conduit Purchaser(s) fails to purchase all or any portion of the related Delayed Amount on the related Delayed Funding Date, each Delaying Committed Purchaser in such Delaying Purchaser Group shall purchase all or the remaining portion, as applicable, of the related Delayed Amount on the related Delayed Funding Date, in each case, in accordance with Section 2.03. Notwithstanding any provision hereof to the contrary, the Transferor may at any time prior to the Delayed Funding Date revoke by written notice to the applicable Delaying Purchaser Group any Notice of Incremental Funding with respect to all or any portion of a Delayed Amount constituting a Delayed Funding Shortfall Amount and the related Delaying Committed Purchaser or Delaying Purchaser Group will not be entitled to any indemnification by the Transferor due solely to such revocation or reduction. On each Delayed Funding Date, the related Delaying Purchaser shall advance (A) the Delayed Funding Reimbursement Amount with respect to the related Delayed Amount by paying such amount in immediately available funds to the Managing Agent for each Non-Delaying Committed Purchaser and each Non-Delaying Purchaser Group, pro rata, based on the relative amount advanced by such Non-Delaying Committed Purchaser or such Non-Delaying Purchaser Group in respect of such Delayed Amount pursuant to Section 2.02(b) and as set forth in a flow of funds agreed to by the Servicer and the Administrative Agent and (B) the Delayed Funding Shortfall Amount with respect to such Delayed Amount by paying such amount in immediately available funds to the account specified in the Notice of Incremental Funding; provided that no advance of the Delayed Funding Shortfall Amount shall be made until the Delayed Funding Reimbursement Amount has been paid in full.

(e) The Transferor shall have the right after the receipt of a Delayed Funding Notice from a Delaying Committed Purchaser or a Delaying Purchaser Group with respect to any Incremental Funding Date, by written notice to such Delaying Committed Purchaser or Delaying Purchaser Group delivered prior to the applicable Delayed Funding Date, to terminate the Commitment of such Delaying Committed Purchaser or of the Conduit Purchaser(s) in such Delaying Purchaser Group and in the event of such termination, the Issuing Entity shall, at the Transferor’s option, either (i) prepay in full the Purchaser Percentage of the Funded Amount of such Delaying Committed Purchaser or of such Delaying Purchaser Group on or prior to such Delayed Funding Date, or (ii) elect to treat the Purchasers in the Delaying Purchaser Group as Non-Extending Purchasers for all purposes of this Agreement and the other Transaction Documents as of the related Delayed Funding Date and, beginning on the first Distribution Date following the Delayed Funding Date, repay the portion of the Funded Amount owing to such Delaying Purchaser Group pursuant to, and in accordance with, the Indenture Supplement; provided, however, that the failure of the Transferor to exercise such right with respect to any Delaying Purchaser Group shall not impair or otherwise affect the right of the Transferor to exercise such option with respect to any subsequent Delayed Funding Notice from such Delaying Purchaser Group.

11

(f) Any prepayment of the Purchaser Percentage of the Funded Amount of a Purchaser Group pursuant to Section 2.02(e)(i) above may be made by the Issuing Entity on a non-pro rata basis with respect to other Purchaser Groups. Notwithstanding anything to the contrary contained in Section 2.02(d), any Delaying Committed Purchaser or Delaying Purchaser Group that the Transferor has elected to prepay in full pursuant to Section 2.02(e) shall have no obligation to fund any further amounts hereunder.

(g) If the Transferor elects to treat the Purchasers in a Delaying Purchaser Group as Non-Extending Purchasers pursuant to Section 2.02(e)(ii) above, then (i) such Delayed Funding Date shall be deemed to be the Scheduled Purchase Expiration Date for such Delaying Purchasers and (ii) such Delaying Purchasers shall continue to be obligated to fund any amount required under Section 2.02(d) on the related Delayed Funding Date.

(h) The advance of a Delayed Funding Shortfall Amount on a Delayed Funding Date is subject to the condition precedent (and each advance of a Delayed Funding Shortfall Amount on a Delayed Funding Date shall constitute the Transferor’s representation and warranty that such condition precedent is satisfied as of the related Delayed Funding Date) that no Insolvency Event with respect to the Transferor or the Servicer shall have occurred as of such Delayed Funding Date.”

p. The second sentence of Section 5.01(k) and the second sentence of Section 5.02(j) are each hereby deleted and shall in each case be replaced with the following:
