SECTION 1.UNCONDITIONAL UNDERTAKING; ENFORCEMENT.

Each Performance Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, to each of the Owners, the Funding Agents and the Administrative Agent (on behalf of the Owners) (collectively, the “Guaranteed Parties”) to cause the due and punctual performance and observance of all the obligations, agreements and undertakings of the RCA Sellers, the RCA Purchaser, the RSA Seller, the Servicer and any Successor Servicer which is an Affiliate of the Servicer (each, a “Guarantee Party”), under the Related Documents to which such Guarantee Party is a party and each other document identified by such Performance Guarantor (in its sole discretion) in writing as a Guaranteed Document (collectively, the “Guaranteed Documents”) to be performed or observed by such Guarantee Party pursuant to the Guaranteed Documents (all such obligations, agreements and undertakings on the part of the Guarantee Parties to be performed or observed under the Guaranteed Documents being collectively called the “Guaranteed Obligations”). Without limiting or expanding the foregoing, it is understood and agreed that the Guaranteed Obligations shall not include, and each Performance Guarantor shall not guaranty or otherwise be liable to any Person for (w) any losses, claims, damages, liabilities or expenses (except to the extent the Guarantee Party would be liable to any such Guaranteed Party under a Guaranteed Document for such losses, claims, damages, liabilities or expenses), (x) losses resulting from the performance or collectibility of the Receivables on account of insolvency, bankruptcy or lack of creditworthiness of the obligors, (y) the non-payment or late payment of any Receivable by the obligor thereof, or (z) any act, inaction, obligation or liability of the Transferor, the Administrative Agent, the Funding Agents or any other Person other than a Guarantee Party or the failure of any of them to fully and punctually pay, perform or comply with any of the terms, covenants, conditions, agreements, undertakings and obligations on the part of such Person to be paid, performed or complied with by it under any of the Related Documents, this Performance Guaranty or otherwise. Each Performance Guarantor shall be liable for the payment of all reasonable costs and expenses paid or incurred by a Guaranteed Party in connection with the collection of all or part of the Guaranteed Obligations from each Performance Guarantor to the extent such costs and expenses are not paid to the Guaranteed Party under the Receivables Purchase and Administration Agreement.

SECTION 2.VALIDITY OF OBLIGATIONS.

Each Performance Guarantor agrees that its obligations under this Agreement shall be absolute and unconditional, irrespective of (i) the validity, enforceability, disaffirmance, settlement or compromise (by any Person other than one of the Guaranteed Parties, including a trustee in bankruptcy) of the Guaranteed Obligations due to the inability of a Guarantee Party to pay or perform such obligation, (ii) the absence of any attempt to collect the Guaranteed Obligations from a Guarantee Party, (iii) any change of the time, manner or place of performance or payment, or any other term of any of the Guaranteed Obligations, (iv) any law, regulation or order of any jurisdiction affecting any terms of any of the Guaranteed Obligations or rights of the Guaranteed Parties with respect hereto due to the inability of a Guarantee Party to pay or perform such obligation (including any estimation, reduction or valuation of the Guaranteed Obligations

2

made in connection with any proceedings involving a Guarantee Party or either Performance Guarantor filed under the Federal Bankruptcy Code, whether pursuant to Section 502 of the Federal Bankruptcy Code or any other Section thereof), and (v) any other circumstance that would otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Performance Guarantor further agrees that, to the extent that a Guarantee Party on its own behalf pursuant to the Related Documents, makes a payment or payments to the Guaranteed Parties in respect of the Guaranteed Obligations which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to its estate, trustee, receiver or any other party, under any bankruptcy law, state or federal law, common law or equitable cause, then to the extent of such payment or repayment, the Guaranteed Obligations or part thereof that has been paid, reduced or satisfied by such amount shall be reinstated and continue in full force and effect as of the date such initial payment, reduction or satisfaction occurred. Each Performance Guarantor waives all set-offs and counterclaims and all presentments, demands for performance, notices of dishonor and notices. After all of the Guaranteed Obligations have been performed or satisfied in full, the relevant Performance Guarantor shall be subrogated to the rights and remedies of the Guaranteed Parties with respect to any Guarantee Party. Each Performance Guarantor agrees that its obligations under this Performance Guaranty shall be irrevocable.
