Section 2.01. Sale of Mortgage Loans; Assignment of the Servicing Agreements.

The Seller, concurrently with the execution and delivery of this Agreement, does hereby sell, assign, set over, and otherwise convey to the Purchaser, without recourse, all of its right, title and interest in, to and under (i) each Mortgage Loan (other than any premium amounts paid by the Seller in connection with the purchase of any Mortgage Loan) and the related Mortgage File, including the related Cut-off Date Principal Balance, all interest due thereon after the Cut-off Date and all collections in respect of interest and principal due after the Cut-off Date (and all principal received before the Cut-off Date to the extent such principal relates to a Monthly Payment due after the Cut-off Date) (other than (a) the Servicing Rights with respect to the SRO Mortgage Loans and (b) any Reserved Rights with respect to the Mortgage Loans); (ii) property which secured such Mortgage Loan that has become an REO Property; (iii) its interest in any insurance policies in respect of the Mortgage Loans (including any insurance proceeds) and (iv) all proceeds of any of the foregoing.

Concurrently with the execution and delivery of this Agreement, the Seller hereby assigns to the Purchaser all of its rights and interest (but none of its obligations) under the Servicing Agreements and the Assignment Agreements (other than (a) the Servicing Rights with respect to the SRO Mortgage Loans and (b) the Reserved Rights with respect to the Mortgage Loans. The Purchaser hereby accepts such assignment, and shall be entitled to exercise all such rights of the Seller under the Servicing Agreements and the Assignment Agreements as if the Purchaser had been a party to each such agreement.

Section 2.02. Obligations of the Seller Upon Sale and Assignment.

In connection with the transfer pursuant to Section 2.01 hereof, the Seller further agrees, at its own expense, on or prior to the Closing Date, (a) to indicate in its books and records that the Mortgage Loans have been sold to the Purchaser pursuant to this Agreement and (b) to deliver to the Purchaser and the Trustee a computer file containing a true and complete list of all such Mortgage Loans specifying for each such Mortgage Loan, as of the Cut-off Date, (i) its account number and (ii) the Cut-off Date Principal Balance and such file, which forms a part of Schedule A to the Pooling and Servicing Agreement, shall also be marked as Schedule I to this Agreement and is hereby incorporated into and made a part of this Agreement.

In connection with such conveyance by the Seller, the Seller shall, on behalf of the Purchaser, cause the Custodian to deliver and deposit with the Trustee (or a custodian as its designated agent), as assignee of the Purchaser, on or before the Closing Date, the documents described in Section 2.01 of the Pooling and Servicing Agreement including, but not limited to, the original Mortgage Notes and the Servicing Agreements. Notwithstanding the foregoing, the Seller will not be under any obligation to deliver, indirectly through a custodian, any mortgage loan that is not a Mortgage Loan as defined herein.

The Seller hereby confirms to the Purchaser and the Trustee that it has made the appropriate entries in its general accounting records, to indicate that the Mortgage Loans have been transferred to the Trustee, or a custodian appointed pursuant to the Pooling and Servicing Agreement to act on behalf of the Trustee, and that the Mortgage Loans constitute part of the Trust in accordance with the terms of the Pooling and Servicing Agreement.

The Purchaser hereby acknowledges its acceptance of all right, title and interest in, to and under the Mortgage Loans and other property, and its rights under the Servicing Agreements and the Assignment Agreements, now existing or hereafter created, conveyed to it pursuant to Section 2.01 hereof.

The parties hereto intend that the transaction set forth herein be a non-recourse sale by the Seller to the Purchaser of all of the Seller’s right, title and interest in, to and under the Mortgage Loans and other property described in Section 2.01. Nonetheless, in the event the transaction set forth herein is deemed not to be a sale, the Seller hereby grants to the Purchaser a security interest in all of the Seller’s right, title and interest in, to and under the Mortgage Loans and other property described in Section 2.01, whether now existing or hereafter created, to secure all of the Seller’s obligations hereunder; and this Agreement shall constitute a security agreement under applicable law, including, without limitation, Articles 8 and 9 of the Uniform Commercial Code in effect in the applicable state). The Seller authorizes the Purchaser, to the extent consistent with this Agreement, to take such actions with respect to the filing and continuation of UCC financing statements as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Pooling and Servicing Agreement. Without limiting the generality of the foregoing, the Seller hereby agrees to take such actions on the Closing Date required of the Seller by Section 2.01 of the Pooling and Servicing Agreement as are necessary under applicable law (including but not limited to the relevant UCC) in order to perfect the interest of the Trustee in the related Mortgaged Property.

Section 2.03. Payment of Purchase Price for the Mortgage Loans. In consideration of the sale of the Mortgage Loans from the Seller to the Purchaser on the Closing Date, the Purchaser agrees to pay to the Seller on the Closing Date by transfer of immediately available funds, an amount equal to $511,061,991.38 (which amount includes accrued interest), and transfer of the Class X, Class PO, Class ES and Class A-R Certificates and the Subordinate Certificates to the Seller (the “Purchase Price”). The Seller shall pay, and be billed directly for, all reasonable expenses incurred by the Purchaser in connection with the issuance of the Certificates, including, without limitation, fees and expenses of Purchaser’s counsel, fees of the rating agencies requested to rate the Certificates, accountant’s fees and expenses and other out-of-pocket costs, if any.

Section 7.02. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

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 be deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the validity of enforceability of the other provisions of this Agreement.

Section 7.05. Counterparts. This Agreement may be executed in one or more counterparts and by the different parties hereto on separate counterparts, which may be transmitted by telecopier 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 7.06. Further Agreements.

The parties hereto each agree to execute and deliver to the other such additional documents, instruments or agreements as may be necessary or reasonable and appropriate to effectuate the purposes of this Agreement or in connection with the issuance of the Certificates representing interests in the Trust Fund, including the Mortgage Loans.

Without limiting the generality of the foregoing, as a further inducement for the Purchaser to purchase the Mortgage Loans from the Seller, the Seller will cooperate with the Purchaser in connection with the sale of the Certificates. In that connection, the Seller will provide to the Purchaser any and all information and appropriate verification of information, whether through letters of its auditors and counsel or otherwise, as the Purchaser shall reasonably request and will provide to the Purchaser such additional representations and warranties, covenants, opinions of counsel, letters from auditors, and certificates of public officials or officers of the Seller as are reasonably required in connection with the offering of the Certificates.

Section 7.07. Intention of the Parties. It is the intention of the parties that the Purchaser is purchasing, and the Seller is selling, the Mortgage Loans rather than pledging such Mortgage Loans to secure a loan by the Purchaser to the Seller. Accordingly, the parties hereto each intend to treat the transaction as a sale by the Seller, and a purchase by the Purchaser, of the Mortgage Loans. Further, and without limiting the foregoing, the transfer of the Mortgage Loans to the Depositor at the Closing Date will be treated by the Seller for financial accounting and reporting purposes as a sale. The Purchaser will have the right to review the Mortgage Loans and the related Mortgage Files to determine the characteristics of the Mortgage Loans which will affect the Federal income tax consequences of owning the Mortgage Loans and the Seller will cooperate with all reasonable requests made by the Purchaser in the course of such review. The transfer of the Mortgage Loans to the Purchaser at the Closing Date will be treated by the Seller for financial accounting and reporting purposes as a financing.

Section 7.08. Successors and Assigns: Assignment of Purchase Agreement. This Agreement shall bind and inure to the benefit of and be enforceable by the Seller, the Sponsor, the Purchaser and the Trustee. The obligations of the Seller and the Sponsor under this Agreement cannot be assigned or delegated to a third party without the consent of the Purchaser which consent shall be at the Purchaser’s sole discretion, except that the Purchaser acknowledges and agrees that the Seller and the Sponsor may assign its obligations hereunder to any Person into which the Seller or the Sponsor is merged or any corporation resulting from any merger, conversion or consolidation to which the Seller or the Sponsor is a party or any Person succeeding to the business of the Seller or the Sponsor; provided that such Person executes and an agreement of assumption to perform every obligation of the Seller or the Sponsor, as applicable, under this Agreement. The parties hereto acknowledge that the Purchaser is acquiring the Mortgage Loans and the rights of the Seller under the Servicing Agreements and the Assignment Agreements for the purpose of contributing them to a trust that will issue the Certificates representing undivided interests in such Mortgage Loans. As an inducement to the Purchaser to purchase the Mortgage Loans, the Seller acknowledges and consents to the assignment by the Purchaser to the Trustee of all of the Purchaser’s rights against the Seller and the Sponsor pursuant to this Agreement insofar as such rights relate to Mortgage Loans transferred to the Trustee and to the enforcement or exercise of any right or remedy against the Seller and the Sponsor pursuant to this Agreement by the Trustee. Such enforcement of a right or remedy by the Trustee shall have the same force and effect as if the right or remedy had been enforced or exercised by the Purchaser directly. The Seller or the Sponsor, as applicable, shall provide notice of any merger, conversion, consolidation or succession pursuant to this Section 7.08 to the Trustee.

Section 7.09. Survival. The representations and warranties set forth in Sections 3.01 and 3.02 and the provisions of Article V hereof shall survive the purchase of the Mortgage Loans hereunder.
