     Section 6.02 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York and the obligations, rights and remedies of the parties hereunder shall be determined in accordance with such laws. With respect to all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby, each party irrevocably submits to the non-exclusive jurisdiction of the courts of the State of New York and the United States District Court located in the Borough of Manhattan, City of New York, and each party irrevocably waives any objection which it may have at any time to the laying of venue of any suit, action or proceeding arising out of or relating hereto brought in any such court, irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in any inconvenient forum and further irrevocably waives the right to object, with respect to such claim, suit, action or proceeding brought in any such court, that such court does not have jurisdiction over such party, provided that service of process is made by any lawful means.

     Section 6.04 Severability of Provisions. If any one or more of the covenants, agreements, provisions or terms of this Agreement shall be held invalid for any reason whatsoever, then such covenants, agreements, provisions or terms shall he deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the validity or enforceability of the other provisions of this Agreement.

     Section 6.05 Counterparts. This Agreement may be executed in one or more counterparts and by the different parties hereto on separate counterparts, each of which, when so executed, shall be deemed to be an original and such counterparts, together, shall constitute one and the same agreement.

     Section 6.06 Further Agreements. The Loan Originator and the Depositor each agree to execute and deliver to the other such amendments to documents and such additional documents, instruments or agreements as may be necessary or appropriate to effectuate the purposes of this Agreement or in connection with the offering of securities representing interests in the Loans.

     Section 6.07 Intention of the Parties; Security Interest.

          (a) Each transfer and assignment contemplated by this Agreement shall constitute a sale in part, and a contribution to capital in part, of the Loans from the Loan Originator to the Depositor. Upon the consummation of those transactions the Loans shall be owned by and the property of the Depositor, and not owned by or otherwise the property of, the Loan Originator for any purpose including without limitation any bankruptcy, receivership, insolvency, liquidation, conservatorship or similar proceeding relating to either the Loan Originator or the Depositor or any property of either. The parties hereto hereby acknowledge that the Depositor and its creditors are relying, and its subsequent transferees and their creditors will rely, on such sales and contributions being recognized as such. If (A) any transfer and assignment contemplated hereby is subsequently determined for any reason under any circumstances to constitute a transfer to secure a loan rather than a sale in part, and a contribution in part, of the Loans or (B) any Loan is otherwise held to be property of the Loan Originator, then this Agreement (i) is and shall be a security agreement within the meaning of Articles 8 and 9 of the applicable Uniform Commercial Code and (ii) shall constitute a grant by the Loan Originator to the Depositor of a security interest in all of the Loan Originator’s right, title and other ownership interest in and to the Loans and the proceeds and other distributions and payments and general intangibles and other rights and benefits in respect thereof. For purposes of perfecting that security interest under any applicable Uniform Commercial Code, the possession by, and notices and other communications with respect thereto to and from, the Depositor or any agent thereof, of money, notes and other documents evidencing ownership of

9

and other rights with respect to the Loans shall be “possession” by the secured party or purchaser and required notices and other communications to and from applicable financial intermediaries, bailees and other agents.

          (b) The Loan Originator at its expense shall take such actions as may be necessary or reasonably requested by the Depositor to ensure the perfection, and priority to all other security interests, of the security interest described in the preceding paragraph including without limitation the execution and delivery of such financing statements and amendments thereto, continuation statements and other documents as the Depositor may reasonably request.

     Section 6.08 Successors and Assigns; Assignment of Agreement. This Agreement shall bind and inure to the benefit of and be enforceable by the Loan Originator, the Depositor, the Indenture Trustee and the Noteholder. The obligations of the Loan Originator under this Agreement cannot be assigned or delegated to a third party without the consent of each of the Depositor and the Noteholder, which consent shall be at each such Person’s sole discretion. The parties hereto acknowledge that the Depositor is acquiring the Loans for the purpose of contributing them to the Trust that will issue the related Notes, which will be secured by such Loans. As an inducement to the Depositor to purchase the Loans and to the Noteholder to purchase the Note, the Loan Originator acknowledges and consents to the assignment by the Depositor to the Trust of all of the Depositor’s rights against the Loan Originator pursuant to this Agreement and to the enforcement or exercise of any right or remedy against the Loan Originator pursuant to this Agreement by the Owner Trustee, for the benefit of the Issuer and the Noteholders, under the related Sale and Servicing Agreement. Such enforcement of a right or remedy by the Owner Trustee, for the benefit of the Issuer and the Noteholders, shall have the same force and effect as if the right or remedy had been enforced or exercised by the Depositor directly.

     Section 6.09 Survival. The representations and warranties set forth in Article III and the provisions of Articles II, IV, V and VI shall survive the purchase of the Loans hereunder.

     Section 6.10 Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and permitted assigns.

     IN WITNESS WHEREOF, the Loan Originator and the Depositor have caused this Loan Purchase and Contribution Agreement to be duly executed on their behalf by their respective officers thereunto duly authorized as of the day and year first above written.
