Upon receipt of the Depositor's Custodian Certification, the Depositor shall deliver to the Custodian a Transfer Certificate acknowledging the Transfer of the Receivables from the Depositor to the Issuing Entity pursuant to the Sale and Servicing Agreement. Upon its receipt of such Transfer Certificate, the Custodian shall acknowledge such Transfer Certificate as provided thereon and deliver to the Issuing Entity a Custodian Certification (the "Issuing Entity's Custodian Certification") certifying that it is holding the Receivable Files delivered to it by the Originator on behalf of the Issuing Entity.

On and after the Delivery Date and the completion of the Transfers described above, and so long as this Agreement shall remain in effect, Custodian shall hold the Receivable Files now and thereafter, from time to time, in its sole custody and control as custodian for the Indenture Trustee, unless and until released from the lien of the Indenture and otherwise in accordance with the Sale and Servicing Agreement, in which event, Custodian shall hold the Receivables and the Receivable Files as custodian for the benefit of the applicable Receivables Holder.

Upon issuance of a Custodian Certification with respect to any Transfer, the Custodian Certification relating to such Receivable previously delivered shall be deemed and marked cancelled with respect to such Receivable.

From time to time and as provided in the Sale and Servicing Agreement, Custodian is hereby authorized, upon written request of Servicer (with the approval of the Indenture Trustee, which approval shall not be unreasonably withheld) in the form annexed as Exhibit B, to release to the Servicer the Receivable File related to any Receivable or the specific documents identified in such request by the Servicer. All documents so released to the Servicer shall be held by it in trust for the benefit of the Indenture Trustee. Servicer shall return the Receivable File, or such other documents which have been released to Servicer, to Custodian when Servicer's need therefor in connection with a foreclosure, modification, termination or repossession no longer exists, unless the Receivable shall be satisfied in full or liquidated, in which case, upon receipt of a certification to such effect from Servicer to Custodian in the form annexed as Exhibit B, the related Receivable File shall be released by Custodian to Servicer, and Custodian shall thereupon reflect any such liquidation of the related Receivable. Pursuant to Section 4.07 of the Sale and Servicing Agreement, (i) the Servicer shall return a Receivable File released to it within five Business Days of such release and (ii) if such Receivable File has not been returned to the Custodian within such five Business Day period, the Servicer shall repurchase the related Receivable.

Upon the purchase of any Receivable pursuant to Section 3.02, 3.05 or 4.07 of the Sale and Servicing Agreement or Section 6.02 of the Purchase Agreement, or upon the payment in full of any Receivable, which shall be evidenced by Custodian's receipt of the request for release in the form annexed hereto as Exhibit B, Custodian shall promptly release the related Receivable File to Servicer and the security interest in such Receivable and related Receivable File granted by the Issuing Entity to the Indenture Trustee pursuant to the Indenture shall terminate without any further action by the Custodian, the Originator, the Depositor or the Indenture Trustee.

The Depositor will pay all fees of Custodian in connection with the performance of its duties hereunder in accordance with written agreements to be entered into from time to time between the Depositor and Custodian, including fees and expenses of counsel incurred by Custodian in the performance of its duties hereunder; provided, however, that (i) Custodian shall in no event acquire any lien upon any Receivable or Receivable File held under this Agreement or the Purchase Agreement or the Sale and Servicing Agreement, or any claim against any Receivables Holder by reason of the failure of the Depositor to pay any of such charges or expenses and (ii) in the event the Depositor fails to pay the fees and expenses of Custodian as set forth in such written agreements, Custodian shall have no obligation to take actions or incur costs in connection with this Agreement unless the Depositor or another Person has made adequate provision for payment of Custodian's fees and expenses.

Except with respect to the willful misconduct of the Custodian, neither the Custodian nor its directors, officers and agents shall be held liable for any indirect or consequential damages resulting from any action taken or omitted to be taken by it or them under or in connection with this Agreement, even if advised of the possibility of such damages. The provisions of this Section 5.6 shall survive the termination of this Agreement.

Servicer agrees to indemnify Custodian against, and to hold it harmless from, any liabilities, and any related out-of-pocket expenses, which it may incur in connection with this Agreement, the Sale and Servicing Agreement, the Purchase Agreement or the Custodian Certifications, other than any liabilities and expenses arising out of Custodian's negligence or willful misconduct.

This indemnity shall include indemnification as to reasonable attorneys' fees and costs, whether or not suit be brought, and including such fees and costs on appeal. The Indenture Trustee shall give prompt written notice to Custodian of any claim for which indemnity is or may be sought and shall afford to Custodian the opportunity to defend such claim.

Section 5.8. Further Rights of Custodian.

(a) If Custodian is at any time uncertain of its obligations hereunder, Custodian, upon prior written notice to the Indenture Trustee, the Issuing Entity, the Originator, the Depositor and the Servicer, may refrain from taking any action with respect to such matter until such uncertainty is removed. If conflicting demands are made on Custodian with respect to any matter, the Indenture Trustee's demand shall control, except during the period prior to the issuance of the Trustee's Custodian Certification pursuant to Section 3.1 hereof, when the applicable Receivables Holder's demand shall control and Custodian shall have the right to rely on such controlling demand. Custodian shall have the right in any such case to interplead any or all of the documents contained in the Receivable Files in a court of competent jurisdiction and, upon delivery thereof, shall have no further obligations thereunder with respect to such documents.

(b) The obligations of Custodian shall be determined solely by the express provisions of this Agreement. No representation, warranty, covenant or obligation of Custodian shall be implied with respect to this Agreement or Custodian's service hereunder. Without limiting the generality of the foregoing statement, except as specifically required herein, Custodian shall be under no obligation to inspect, review or examine the Receivable Files to determine that the contents thereof are complete, genuine, enforceable or appropriate for the represented purpose or that they have been actually recorded or filed in required offices or that they are other than what they purport to be on their face.

(c) No provision of this Agreement shall require Custodian to spend or risk its own funds or otherwise incur financial liability in performance of its duties under this Agreement unless, pursuant to Section 5.2 hereof, adequate provision has been made for the reimbursement of Custodian's expenses hereunder.
