ASSET REPRESENTATIONS REVIEW PROCESS

Section 3.01 Asset Representations Review Notices and Identification of Review Receivables.

On receipt of an Asset Representations Review Notice from the Seller according to Section 5.7 of the Receivables Purchase Agreement, the Asset Representations Reviewer will start an Asset Representations Review. The Servicer will provide the list of Review Receivables to the Asset Representations Reviewer promptly upon receipt of the Asset Representations Review Notice.

The Asset Representations Reviewer will not be obligated to start, and will not start, an Asset Representations Review until an Asset Representations Review Notice and the related list of Review Receivables is received. The Asset Representations Reviewer is not obligated to verify (i) whether the conditions to the initiation of the Asset Representations Review and the issuance of an Asset Representations Review Notice described in Section 7.6 of the Indenture were satisfied or (ii) the accuracy or completeness of the list of Review Receivables provided by the Servicer.

Section 3.02 Review Materials.

(a) Access to Review Materials. Within 60 days of the Noteholder vote approving the Asset Representations Review pursuant to Section 7.6 of the Indenture, the Servicer will provide the Asset Representations Reviewer with access to the Review Materials for all Review Receivables in one or more of the following ways, at its option: (i) by providing access to the Servicer’s systems, either remotely or at an office of the Servicer, (ii) by electronic posting to a password-protected website to which the Asset Representations Reviewer has access, (iii) by providing originals or photocopies at an office of the Servicer or (iv) in another manner agreed by the Servicer and the Asset Representations Reviewer. The Servicer may redact or remove Personally Identifiable Information from the Review Materials without changing the meaning or usefulness of the Review Materials. The Asset Representations Reviewer shall be entitled to rely in good faith, without independent investigation or verification, that the Review Materials are accurate and complete in all material respects, and not misleading in any material respect.

(b) Missing or Insufficient Review Materials. Upon receipt of the Review Materials, the Asset Representations Reviewer will review the Review Materials to determine if any Review Materials are missing or insufficient for the Asset Representations Reviewer to perform any Test. If the Asset Representations Reviewer determines any missing or insufficient Review Materials, the Asset Representations Reviewer will notify the Servicer promptly, and in any event no less than 20 calendar days before completing the Asset Representations Review. The Servicer will have 15 calendar days to give the Asset Representations Reviewer access to the missing Review Materials or other documents or information to correct the insufficiency. If the missing Review Materials or other documents have not been provided by the Servicer within 15 calendar days, the related Review Report will report a Test Fail for each Test that requires use of the missing or insufficient Review Materials.

Section 3.03 Performance of Reviews.

(a) Test Procedures. For an Asset Representations Review, the Asset Representations Reviewer will perform, for each Review Receivable, the Tests for each Eligible Representation. In the course of its review, the Asset Representations Reviewer will use the Review Materials listed in Schedule A as specified in the description of each Test under Schedule B. For each Test and Review Receivable, the Asset Representations Reviewer will determine if the Test has been satisfied (a “Test Pass”) or if the Test has not been satisfied (a “Test Fail”). During the course of its review, the Asset Representations Reviewer will provide the Issuer and the Servicer with a preliminary list of any Test Fail and the issues identified and, at that time, the Servicer has the option of electing to provide additional Review Materials or information which the Asset Representations Reviewer will analyze and consider in preparing the Review Report.

(b) Review Period. The Asset Representations Reviewer will complete the Asset Representations Review within 60 days of receiving access to the Review Materials. However, if missing or additional Review Materials are provided to the Asset Representations Reviewer as described in Sections 3.02(b) or 3.03(a), the Asset Representations Review period will be extended for an additional 30 days.

(c) Completion of Review for Certain Review Receivables. Following the delivery of the list of the Review Receivables and before the delivery of the Review Report by the Asset Representations Reviewer, the Servicer may notify the Asset Representations Reviewer if a Review Receivable is paid in full by the Obligor or otherwise satisfied or repurchased from the Issuer in accordance with Section 3.5 of the Receivables Purchase Agreement or Sections 2.4 or 3.7 of the Sale and Servicing Agreement. On receipt of such notice, the Asset Representations Reviewer will immediately terminate all Tests of the related Review Receivable, and the Asset Representations Review of such Review Receivable will be considered complete (a “Test Complete”). In this case, the related Review Report will indicate a Test Complete for such Review Receivable and the related reason.

(d) Previously Reviewed Receivables; Duplicative Tests. If any Review Receivable was included in a prior Review, the Asset Representations Reviewer will not conduct additional Tests on such Review Receivable, but will include the previously reported Test results in the Review Report for the current Review. If the same Test is required for more than one Eligible Representation, the Asset Representations Reviewer will only perform the Test once for each Review Receivable, but will report the results of the Test for each applicable Eligible Representation on the Review Report.

(e) Termination of Review. If an Asset Representations Review is in process and the Notes will be paid in full on the next Distribution Date, the Issuer or the Servicer will notify the Asset Representations Reviewer no less than 10 days before that Distribution Date. On receipt of such notice, the Asset Representations Reviewer will terminate the Asset Representations Review immediately and will not be obligated to deliver a Review Report.

4

(f) Review Systems; Personnel. The Asset Representations Reviewer will maintain business process management and/or other systems necessary to ensure that it can perform each Test and, on execution of this Agreement, will load each Test into these systems. The Asset Representations Reviewer will ensure that these systems allow for each Review Receivable and the related Review Materials to be individually tracked and stored as contemplated by this Agreement. The Asset Representations Reviewer will maintain adequate staff who are properly trained to conduct Reviews as required by this Agreement.

Section 3.04 Review Report.

Within 5 Business Days after the end of the applicable Asset Representations Review period under Section 3.03(b), the Asset Representations Reviewer will deliver to the Issuer, the Administrator, the Servicer, the Depositor and the Indenture Trustee a report indicating for each Review Receivable whether there was a Test Pass, Test Fail or Test Complete for each related Test (a “Review Report”). For each Test Fail or Test Complete, the Review Report will indicate the related reason, including (for example) whether the Review Receivable was a Test Fail as a result of missing or incomplete Review Materials. The Review Report will contain a summary of the Asset Representations Review results to be included in the Issuer’s Form 10-D report for the Collection Period in which the Review Report is received. The Asset Representations Reviewer will ensure that the Review Report does not contain any PII. On reasonable request of the Servicer, the Asset Representations Reviewer will provide additional details on the Test results.

Section 3.05 Review Representatives.

(a) Servicer Representative. The Servicer will designate one or more representatives who will be available to assist the Asset Representations Reviewer in performing the Asset Representations Review, including responding to requests and answering questions from the Asset Representations Reviewer about access to Review Materials on the Servicer’s or Seller’s originations, receivables or other systems, obtaining missing or insufficient Review Materials and/or providing clarification of any Review Materials or Tests.

(b) Asset Representations Review Representative. The Asset Representations Reviewer will designate one or more representatives who will be available to the Issuer and the Servicer during the performance of an Asset Representations Review.

(c) Questions About Review. The Asset Representations Reviewer will make appropriate personnel available to respond in writing to written questions or requests for clarification of any Review Report from the Indenture Trustee or the Servicer until the earlier of (i) the payment in full of the Notes and (ii) one year after the delivery of such Review Report. The Asset Representations Reviewer will not be obligated to respond to questions or requests for clarification from Noteholders or any other Person and will direct such Persons to submit written questions or requests to the Servicer.

Section 3.06 Dispute Resolution.

If a Review Receivable that was the subject of an Asset Representations Review becomes the subject of a dispute resolution proceeding under Section 2.4(d) of the Sale and Servicing Agreement, the Asset Representations Reviewer will participate in the dispute resolution proceeding on request of a party to the proceeding. The reasonable out-of-pocket expenses of the Asset Representations Reviewer for its participation in any dispute resolution proceeding will

5

be considered expenses of the requesting party for the dispute resolution and will be paid by a party to the dispute resolution as determined by the mediator or arbitrator for the dispute resolution according to Section 2.4(d) of the Sale and Servicing Agreement. If not paid by a party to the dispute resolution, the expenses will be reimbursed in accordance with Section 4.02(d).

Section 3.07 Limitations on Review Obligations.

(a) Review Process Limitations. The Asset Representations Reviewer will have no obligation (i) to determine whether a Delinquency Trigger Event has occurred or whether the required percentage of Noteholders has voted to direct an Asset Representations Review under the Indenture, (ii) to determine which Receivables are subject to an Asset Representations Review, (iii) to obtain or confirm the validity of the Review Materials, (iv) to obtain missing or insufficient Review Materials except as specifically described herein, (v) to take any action or cause any other party to take any action under any of the Transaction Documents to enforce any remedies for breaches of representations or warranties about the Eligible Representations, (vi) to determine the reason for the delinquency of any Review Receivable, the creditworthiness of any Obligor, the overall quality of any Review Receivable or the compliance by the Servicer with its covenants with respect to the servicing of such Review Receivable, or (vii) to establish cause, materiality or recourse for any failed Test as described in Section 3.03.

(b) Testing Procedure Limitations. The Asset Representations Reviewer will only be required to perform the Tests, and will not be obligated to perform additional procedures on any Review Receivable or to provide any information other than a Review Report. However, the Asset Representations Reviewer may provide additional information in a Review Report about any Review Receivable that it determines in good faith to be material to the Asset Representations Review.

(c) Maintenance of Review Materials. The Asset Representations Reviewer will maintain copies of any Review Materials, Review Reports and other documents relating to an Asset Representations Review, including internal correspondence and work papers, until the earlier of (i) payment in full of the Notes and (ii) one year after the delivery of the applicable Review Report.

The Asset Representations Reviewer will maintain all relevant books, records, reports and other documents and materials for a period of at least two years after the termination of its obligations under this Agreement.

Section 4.07 Delegation of Obligations. The Asset Representations Reviewer may not delegate or subcontract its obligations under this Agreement to any Person without the consent of the Issuer and the Servicer, which consent will not be unreasonably withheld or delayed.

The Confidential Information will not, without

10

the prior consent of the Issuer and the Servicer, be disclosed or used by the Asset Representations Reviewer, or its officers, directors, employees, agents, representatives or affiliates, including legal counsel (collectively, the “Information Recipients”) other than for the purposes of performing Reviews of Review Receivables or performing its obligations under this Agreement. The Asset Representations Reviewer agrees that it will not, and will cause its Affiliates to not (i) purchase or sell securities issued by the Seller or its Affiliates or special purpose entities on the basis of Confidential Information or (ii) use the Confidential Information for the preparation of research reports, newsletters or other publications or similar communications.

(d) Disclosure. If the Asset Representations Reviewer is required by applicable law, regulation, rule or order issued by an administrative, governmental, regulatory or judicial authority to disclose part of the Confidential Information, it may disclose the Confidential Information. However, before a required disclosure, the Asset Representations Reviewer, if permitted by law, regulation, rule or order, will use its reasonable efforts to provide the Issuer

11

and the Servicer with notice of the requirement and will cooperate, at the Servicer’s expense, in the Issuer’s and the Servicer’s pursuit of a proper protective order or other relief for the disclosure of the Confidential Information.
