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 Class 1A-1, Class 2A-1, Class 3A-1 and Class 3A-2 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. 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 hereof. 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. 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 hereof, 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. The Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions 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. 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.

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 Purchaser and the Trustee. The obligations of the Seller 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 may assign its obligations hereunder to any Person into which the Seller is merged or any corporation resulting from any merger, conversion or consolidation to which the Seller is a party or any Person succeeding to the business of the Seller. The parties hereto acknowledge that the Purchaser is acquiring the Mortgage Loans and the rights of the Seller under the Servicing Agreements for the purpose of selling them to the 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 Trust of all of the Purchaser’s rights against the Seller pursuant to this Agreement insofar as such rights relate to Mortgage Loans transferred to the Trust and to the enforcement or exercise of any right or remedy against the Seller 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.

7

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.

SCHEDULE III

SELLER’S REPRESENTATIONS AND

WARRANTIES RELATING TO

MORTGAGE LOANS

The Seller hereby represents and warrants to, and covenants with, the Purchaser that, as to each Mortgage Loan, as of the Closing Date:

(i) The information set forth in the final Mortgage Loan Schedule is complete, true and correct in all material respects and (b) the Mortgage Note or an affidavit of lost note with respect to each Mortgage Loan has been delivered to the Purchaser or its designee.

(ii) As of the Cut-off Date, none of the Mortgage Loans (by Stated Principal Balance) were 30 or more days delinquent in payment.

(iii) To the best of Seller’s knowledge, there are no delinquent taxes, ground rents, water charges, sewer rents, assessments, insurance premiums, leasehold payments, including assessments payable in future installments or other outstanding charges affecting the related Mortgaged Property or escrow funds have been established in an amount sufficient to pay for every such escrowed item which remains unpaid.

(iv) The terms of the Mortgage Note and the Mortgage (including with respect to provisions relating to any Additional Collateral (if applicable)) have not been impaired, waived, altered or modified in any respect, except by written instruments which have been recorded, if necessary to protect the interests of the Trust, and which are included in the Mortgage File, the substance of which waiver, alteration or modification has been approved by the primary mortgage guaranty insurer, if any, and by the title insurer, in each instance to the extent required by the related policy and is reflected on the Mortgage Loan Schedule. Except for any modification agreement or similar document contained in the Mortgage File permitting a borrower to modify his Mortgage Loan, no instrument of waiver, alteration or modification has been executed, and no Mortgagor has been released, in whole or in part, except in connection with an assumption agreement approved by the primary mortgage insurer, if any, and title insurer, in each instance to the extent required by the policy, and which assumption agreement is part of the Mortgage File.

(v) The Mortgage Note and the Mortgage (including with respect to provisions relating to any Additional Collateral (if applicable)) are not subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, nor will the operation of any of the terms of the Mortgage Note and Mortgage, or the exercise of any right thereunder, render the Mortgage unenforceable, in whole or in part, or subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, and to the Seller’s knowledge no such right of rescission, set-off, counterclaim or defense has been asserted with respect thereto.

III-1

(vi) All buildings upon the Mortgaged Property are insured by a generally acceptable insurer against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located. All such insurance policies contain a standard mortgagee clause naming the Master Servicer or the applicable Servicer, their successors and assigns as mortgagee and to Seller’s knowledge all premiums thereon have been paid. If upon origination of the Mortgage Loan, the Mortgaged Property was in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been made available) a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration is in effect. The Mortgage obligates the Mortgagor thereunder to maintain all such insurance at the Mortgagor’s cost and expense, and on the Mortgagor’s failure to do so, authorizes the holder of the Mortgage to maintain such insurance at the Mortgagor’s cost and expense and to seek reimbursement therefor from the Mortgagor.

(vii) The Mortgage Loan is not a loan (A) subject to 12 CFR Part 226.31, 12 CFR Part 226.32 or 12 CFR Part 226.34 of Regulation Z, the regulation implementing TILA, which implements the Home Ownership and Equity Protection Act of 1994, as amended, or any comparable state law (B) a “High Cost Loan” or “Covered Loan” as applicable, as such terms are defined in the current Standard & Poor’s LEVELS® GLOSSARY classified and/or defined as a “high cost” loan or “predatory,” “high cost,” “threshold” or “covered” lending under any other state, federal or local law. The Mortgage Loan at the time it was made otherwise complied in all material respects with any and all requirements of any federal, state or local law including, but not limited to, all predatory lending laws, usury, truth in lending, real estate settlement procedures (including the Real Estate Settlement Procedures Act of 1974, as amended), consumer credit protection, equal credit opportunity or disclosure laws applicable to such Mortgage Loan.

(viii) The Mortgage has not been satisfied, canceled or subordinated, or rescinded, in whole or in part, and the Mortgaged Property has not been released from the lien of the Mortgage except for a release that does not materially impair the security of the Mortgage Loan or is reflected in the Loan-to-Value Ratio, in whole or in part, nor has any instrument been executed that would effect any such release, cancellation, subordination or rescission unless payoff funds have been deposited in the custodial account.

(ix) The Mortgage is a valid, existing and enforceable first lien on the Mortgaged Property, including all improvements on the Mortgaged Property subject only to (A) the lien of current real property taxes and assessments not yet due and payable, (B) covenants, conditions and restrictions, rights of way, easements and other matters of the public record as of the date of recording being acceptable to mortgage lending institutions generally and either (a) specifically referred to in a lender’s title insurance policy delivered to the related Originator of the Mortgage Loan or (b) which do not adversely affect the Appraised Value of the Mortgaged Property, and (C) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by the Mortgage or the use, enjoyment, value or marketability of the related Mortgaged Property; and, further provided, with respect to Cooperative Loans, the lien of the related cooperative corporation for unpaid assessments representing the obligor’s pro rata share of the cooperative corporation’s payments for its blanket mortgage, current and future real property taxes, insurance premiums, maintenance fees and other assessments to which like collateral is commonly subject. Any security agreement, chattel mortgage or equivalent document related to and delivered in connection with the Mortgage establishes and creates a valid, existing and enforceable first lien and first priority security interest on the property described therein and the Seller has full right to sell and assign the same to the Purchaser.

III-2

(x) The Mortgage Note and the related Mortgage are genuine and each is the legal, valid and binding obligation of the maker thereof, enforceable in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, or reorganization or other laws relating to the rights of creditors and general principles of equity.

(xi) All parties to the Mortgage Note and the Mortgage had legal capacity to enter into the Mortgage Loan and to execute and deliver the Mortgage Note and the Mortgage, and the Mortgage Note and the Mortgage have been duly and properly executed by such parties.
