(b)    Section 1.8(b) of the Agreement is hereby amended by replacing the term “Eurodollar Rate” in each instance where it appears therein with the phrase “Eurodollar Rate or LMIR”.

(c)    Section 1.11 of the Agreement is hereby replaced in its entirety with the following:

Section 1.11. Inability to Determine Eurodollar Rate or LMIR; Change in Legality.

(a)    If any Funding Agent shall have determined before the first day of any Accrual Period (or solely with respect to LMIR, on any day) (which determination shall be conclusive and binding upon the parties hereto), by reason of circumstances affecting the interbank Eurodollar market, either that: (i) dollar deposits in the relevant amounts and for the relevant Accrual Period (or portion thereof) are not available, (ii) adequate and reasonable means do not exist for ascertaining the Eurodollar Rate or LMIR for such Accrual Period (or portion thereof) or (iii) the Eurodollar Rate or LMIR determined pursuant hereto does not accurately reflect the cost to the applicable Affected Person (as conclusively determined by such Funding Agent) of maintaining any Portion of Capital during such Accrual Period (or portion thereof), such Funding Agent shall promptly give telephonic notice of such determination, confirmed in writing, to the Seller before the first day of such Accrual Period (or solely with respect to LMIR, on such day). Upon delivery of such notice: (i) no Portion of Capital shall be funded thereafter at the Alternate Rate determined by reference to the Eurodollar Rate or LMIR unless and until such Funding Agent shall have given notice to the Seller that the circumstances giving rise to such determination no longer exist, and (ii) with respect to any outstanding Portions of Capital then funded at the Alternate Rate determined by reference to the Eurodollar Rate or LMIR, such Alternate Rate shall, on the immediately succeeding Accrual Date (or solely with respect to LMIR, immediately), automatically be converted to the Alternate Rate determined by reference to the Base Rate at the respective last days of the then-current Accrual Periods (or solely with respect to LMIR, immediately) relating to such Portions of Capital.

(b)    If, on or before the first day of any Accrual Period (or solely with respect to LMIR, on any day), any Funding Agent shall have been notified by any Affected Person that such Affected Person has determined (which determination shall be final and conclusive) that any Change in Law, or compliance by such Affected Person with any Change in Law, shall make it unlawful or impossible for such Affected Person to fund or maintain any Portion of Capital at or by reference to the Eurodollar Rate or LMIR, such Funding Agent shall notify the Seller, the Collateral Agent and each other Funding Agent thereof. Upon receipt of such notice, until the applicable Funding Agent notifies the Seller, the Collateral Agent and each other Funding

Agent that the circumstances giving rise to such determination no longer apply, (i) no Portion of Capital shall be funded at or by reference to the Eurodollar Rate or LMIR and (ii) the Discount for any outstanding Portions of Capital then funded at the Alternate Rate determined by reference to the Eurodollar Rate or LMIR shall be converted to the Alternate Rate determined by reference to the Base Rate either (x) on the last day of the then current Accrual Period (or solely with respect to LMIR, immediately) if such Affected Person may lawfully continue to maintain such Portion of Capital at or by reference to the Eurodollar Rate or LMIR to such day, or (y) immediately, if such Affected Person may not lawfully continue to maintain such Portion of Capital at or by reference to the Eurodollar Rate or LMIR to such day.

IN WITNESS WHEREOF, the parties have caused this Amendment to be executed by their respective officers thereunto duly authorized, as of the date first above written.

The Seller hereby designates [Insert Name of Designated Obligor], now a Classified Obligor, a “Designated Obligor” pursuant to the terms of the request dated [Insert Date of Request], the acceptance dated [Insert Date of Acceptance] and the RPA.

Accordingly, effective as of the date hereof, the following Classified Obligors now constitute Designated Obligors under the RPA:

This is a request that [Insert Name of Excluded Obligor] (the “Reinstated Obligor”), solely with respect to receivables created on and after [Insert Date], no longer be classified as an “Excluded Obligor” [and instead be classified as a “Classified Obligor”]² pursuant to the terms hereof and of the RPA.

Each of the Seller and the Servicer, each for itself only, hereby (A) represents and warrants that, immediately prior to and immediately after giving effect to the transactions contemplated by this letter each of the representations, warranties, covenants and agreements made by it under each of the Transaction Documents to which it is a party are true and correct as of the date hereof and no Unmatured Event of Termination or Event of Termination exists or will exist and (B) agrees to provide (or to cause to be provided) to the Collateral Agent and each Funding Agent and Purchaser, executed copies of all documents, agreements, instruments, certificates, UCC financing statements or terminations or other reports, records, or receipts and to make any reasonable adjustments to any reports delivered or to be delivered under the RPA, if any, relating to the subject matter hereof and as the Collateral Agent, any Funding Agent or any Purchaser may from time to time reasonably request.

Each of the Seller and the Servicer understands and acknowledges that each of the Collateral Agent and each Funding Agent is entering into the transactions contemplated by this letter on the express understanding with each of the other parties hereto that, in entering into this letter, it is not establishing any course of dealing with any such Person. Each of the Collateral Agent’s, the Funding Agents’ and the Purchasers’ rights to require strict performance with each of the terms and conditions of the RPA and each other Transaction Document shall not in any way be impaired or affected by the execution hereof, except to the extent expressly set forth herein. None of the Collateral Agent, any Funding Agent or any Purchaser shall be obligated in any manner to execute any future amendments, waivers, letters, agreements, documents or other instruments and if any such amendment, waiver, letter, agreement, document or other instrument is requested in the future, assuming the terms and conditions thereof are otherwise satisfactory to it, each such Person may, in connection with considering whether or not to agree or consent to or acknowledge the terms of any such amendment, waiver, letter, agreement, document or other instrument, require the Seller and/or the Servicer to prepare and deliver (or cause to be prepared and delivered) such other agreements, reports, historical data or other information or documents in order to determine, in its sole discretion, whether or not to agree or consent to or acknowledge the terms and conditions thereof.

We ask that the Collateral Agent and each Funding Agent grant this request by executing this letter in the space provided and returning a copy to the Servicer and each of the other parties hereto. The parties each agree that from and after the date hereof the Reinstated Obligor shall no longer be classified as an Excluded Obligor [and instead shall be classified as a Classified Obligor, in each case]³ solely with respect to receivables created on and after [Insert Date] and the RPA is hereby modified to reflect such modification.

[The Servicer shall notify each of the Collateral Agent, the Funding Agents and the Purchasers in writing prior to designating the Reinstated Obligor (in its capacity as a Classified Obligor) as a Designated Obligor using a notice in the form attached to the RPA as Annex F (the “Designated Obligor Notice”). From and after the date of any Designated Obligor Notice, neither the Seller nor the Servicer shall without the prior written consent of each of the Collateral Agent and the Funding Agents include any Receivables owed by the Reinstated Obligor in any of the calculations of the Default Ratio, Delinquency Ratio or Dilution Ratio under the RPA.]⁴ 

By their execution hereof, each of the Collateral Agent and each Funding Agent agrees the aforementioned Reinstated Obligor is no longer an “Excluded Obligor” [and instead is a “Classified Obligor”]⁵ pursuant to the terms hereof and of the RPA and solely with respect to receivables created on and after [Insert Date].
