Paying Agent or the Escrow Agent, except as expressly provided herein or in the Pass Through Trust Agreement. No Receiptholder shall have any right to vote or in any manner otherwise control the operation and management of the Paying Agent Account (as defined below) or the obligations of the parties hereto, nor shall anything set forth herein, or contained in the terms of any Escrow Receipt, be construed so as to constitute the Receiptholders from time to time as partners or members of an association.

     Any duplicate Escrow Receipt issued pursuant to this Section 1.05 shall constitute conclusive evidence of the appropriate Escrow Interest in the Account Amounts, as if originally issued, whether or not the lost, stolen or destroyed Escrow Receipt shall be found at any time.

     The provisions of this Section 1.05 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Escrow Receipts.

     Section 1.06. Additional Escrow Amounts . On the date of any Purchase Withdrawal, the Pass Through Trustee may re-deposit with the Depositary some or all of the amounts so withdrawn in accordance with Section 2.4 of the Deposit Agreement.

than a majority in interest in the Account Amounts (an “ Action of Investors ”). Upon any such resignation or removal, the Investors, by an Action of Investors, shall have the right to appoint a successor Escrow Agent. If no successor Escrow Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Escrow Agent’s giving of notice of resignation or the removal of the retiring Escrow Agent, then the retiring Escrow Agent may appoint a successor Escrow Agent. Any successor Escrow Agent shall be a bank which has an office in the United States with a combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Escrow Agent hereunder by a successor Escrow Agent, such successor Escrow Agent shall enter into such documents as the Pass Through Trustee shall require and shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be discharged from its duties and obligations hereunder. No resignation or removal of the Escrow Agent shall be effective unless a written confirmation shall have been obtained from each of Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business, and Moody’s Investors Service, Inc., that the replacement of the Escrow Agent with the successor Escrow Agent will not result in ( a ) a reduction of the rating for the Certificates below the then current rating for the Certificates or ( b ) a withdrawal or suspension of the rating of the Certificates.

     Section 1.08. Persons Deemed Owners . Prior to due presentment of a Certificate for registration of transfer, the Escrow Agent and the Paying Agent may treat the Person in whose name any Escrow Receipt is registered (as of the day of determination) as the owner of such Escrow Receipt for the purpose of receiving distributions pursuant to this Agreement and for all other purposes whatsoever, and neither the Escrow Agent nor the Paying Agent shall be affected by any notice to the contrary.

     Section 1.09. Further Assurances . Without limiting Sections 4 and 8 of this Agreement, the Escrow Agent agrees to take such actions, and execute such other documents, as may be reasonably requested by the Pass Through Trustee in order to effectuate the purposes of this Agreement, the Note Purchase Agreement or the Deposit Agreement and the performance by the Escrow Agent of its obligations hereunder or thereunder.
