5

Seller, Depositor and the Issuer 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 this Agreement. Seller and Depositor shall arrange for filing any Uniform Commercial Code continuation statements in connection with any security interest granted or assigned hereunder.

Section 5. Termination.

(a) Depositor may terminate this Agreement, by notice to Seller, at any time at or prior to the Closing Date:

(i) if the Underwriting Agreement is terminated by the Underwriters pursuant to the terms of the Underwriting Agreement or if the Underwriters do not complete the transactions contemplated by the Underwriting Agreement as the result of the failure of any condition set forth therein or if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus or Prospectus Supplement, any material adverse change in the financial condition, earnings, business affairs or business prospects of Seller, whether or not arising in the ordinary course of business, or

(ii) if there has occurred any material adverse change in the financial markets in the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriters, impracticable to market the Bonds or to enforce contracts for the sale of the Bonds, or

(iii) if trading in any securities of Seller has been suspended or limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the NASDAQ National Market System has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or

(iv) if a banking moratorium has been declared by either Federal or New York authorities.

(b) This Agreement shall terminate automatically without any required notice or other action by any party hereto if the Closing Date for the issuance of the Bonds has not occurred by [____________ __, 201_].

(b) Binding Upon Successors, Etc. This Agreement shall bind and inure to the benefit of and be enforceable by Seller, Depositor, the Issuer, and the respective successors and assigns thereof. The parties hereto acknowledge that the Issuer is acquiring the Mortgage Loans for the purpose of pledging, transferring, assigning, setting over and otherwise conveying them to the Trustee, pursuant to the Indenture for inclusion in the Trust Estate. As an inducement to the Issuer to purchase the Mortgage Loans, Seller and Depositor acknowledge and consent to the assignment to the Trustee by the Issuer of all of the Issuer’s rights against Seller and Depositor hereunder in respect of the Mortgage Loans sold to the Issuer and that the enforcement or exercise of any right or remedy against Seller and Depositor hereunder by the Trustee or to the extent permitted under the Indenture shall have the same force and effect as if enforced and exercised by the Issuer directly.

(c) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

(d) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

(e) Headings. The headings of the several parts of this Agreement are inserted for convenience of reference and are not intended to be a part of or affect the meaning or interpretation of this Agreement.

(f) Definitions. Capitalized terms not otherwise defined herein have the meanings ascribed to such terms in the Indenture.

(g) Nonpetition Covenant. Until one year plus one day shall have elapsed since the termination of the Indenture in accordance with its terms, neither Seller nor any assignee of Seller or Depositor or the Issuer shall petition or otherwise invoke the process of any court or government authority for the purpose of commencing or sustaining a case against Depositor or the Issuer under any federal or state bankruptcy, insolvency or similar law or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of Depositor or the Issuer or any substantial part of its property, or ordering the winding up or liquidation of the affairs of Depositor or the Issuer.

(h) Limitation of Liability of Owner Trustee. It is expressly understood and agreed by the parties hereto that (a) this Agreement is executed and delivered in the name and on behalf of the Issuer by Owner Trustee, not individually or personally but solely as owner trustee of Depositor Mortgage Trust 7, in the exercise of the powers and authority conferred and vested in it under the Deposit Trust Agreement, (b) each of the representations, undertakings and agreements herein made on the part of the Issuer is made and intended not as a personal representation, undertaking and agreement by Owner Trustee but is made solely in the name and on behalf of the Issuer and intended for the purpose of binding only the Issuer, and (c) under no circumstances shall Owner Trustee be personally liable for the payment of any indebtedness or expenses of the Issuer or be liable for the breach or failure of any obligation, representation, warranty or covenant made or undertaken by the Issuer under this Agreement or the other Basic Documents or otherwise.
