On the Closing Date, the Original Certificate Principal Balance (or notional amount, as applicable) of each Class of Exchangeable Initial Certificates and Exchangeable Certificates will be the amount set forth for such Class in Section 4.01(d) of the Pooling and Servicing Agreement. With respect to any Distribution Date, the Outstanding Certificate Principal Balance (or notional amount, as applicable) of the Exchangeable Initial Certificates and Exchangeable Certificates will depend upon, among other factors, which exchanges, if any, have taken place hereunder. Any such exchange shall be made in accordance with the requirements set forth in Appendix A.

On or before the Issue Date, the Paying Agent shall either (i) open with a depository institution one or more trust accounts in the name of the Trustee on behalf of the Trust Fund that shall collectively be the “Trust Account,” (ii) in lieu of maintaining any such account or accounts, maintain the Trust Account by means of appropriate entries on its books and records designating all amounts credited thereto in respect of the Uncertificated REMIC Interests and all investments of any such amounts as being held by it in its capacity as Paying Agent for the benefit of the Holders of the Certificates or (iii) maintain the Trust Account in the form of any combination of accounts or book entries described in clauses (i) and (ii) above. Any manner or manners in which the Trust Account is maintained may at any time be changed without notice to, or the approval of, Holders of the Certificates so long as funds held in the Trust Fund by, or for the account of, the Paying Agent shall at all times be identified. To the extent that the Trust Account is maintained by the Paying Agent in the manner provided for in clause (ii) above, all references herein to deposits and withdrawals from the Trust Account shall be deemed to refer to credits and debits to the related books of the Paying Agent.

The Paying Agent shall deposit in the Trust Account all distributions in respect of the Uncertificated REMIC Interests received by it as Paying Agent hereunder. All such distributions deposited from time to time in the Trust Account and all investments made with such moneys, including all income or other gain from such investments, shall be held by the Paying Agent in the Trust Account as part of the Trust Fund as herein provided, subject to withdrawal by the Paying Agent for distributions on the Certificates.

Section 3.03. Distributions. On each Distribution Date, the Paying Agent shall withdraw from the Trust Account the Class Distribution Amount for each Class and shall make the appropriate distributions to the Holders of each such Class. All distributions of such Class Distribution Amount that are made with respect to a particular Class of Certificates shall be made pro rata among all Certificates of such Class in proportion to their respective outstanding principal balances, with no preference or priority of any kind.

Section 3.04. Allocation of Losses and Certain Other Amounts. For the avoidance of doubt, any losses, shortfalls, prepayments or increases in principal amount related to Subsequent Recoveries allocable to the Uncertificated REMIC Interests pursuant to the terms of the Pooling and Servicing Agreement shall result in a proportionate reduction or increase in the Aggregate Denomination of the corresponding Class or Classes of Certificates issued hereunder.

ARTICLE IV

Except as provided in Article V and Article VII, no Certificateholder shall have any right to vote or in any manner otherwise control the operation and management of the Trust Fund or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of the Certificates, be construed so as to constitute the Certificateholders from time to time as partners or members of an association; nor shall any Certificateholder be under any liability to any third person by reason of any action taken by the parties to this Trust Agreement pursuant to any provision hereof.

No Certificateholder shall have any right, by virtue of any provision of this Trust Agreement, to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Trust Agreement unless an Event of Default shall have occurred and be continuing in respect of this Trust Agreement.

Any notice so mailed within the time prescribed in this Trust Agreement shall be conclusively presumed to have been duly given whether or not the Person to whom such notice shall have been directed receives such notice.

Section 8.04. Severability of Provisions. If any one or more of the covenants, agreements, provisions or terms of this Trust Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Trust Agreement and shall in no way affect the validity or enforceability of the other provisions of this Trust Agreement or of the Certificates or the rights of the Holders thereof.

Section 8.05. Tax Status and Reporting. It is the intended that the Trust Fund created hereunder be considered a “grantor trust” under the Code. Based upon such characterization, within a reasonable period of time after the end of each calendar year but not later than the latest date permitted by law, the Paying Agent shall mail to each person who so requests in writing and who at anytime during such calendar year shall have been a Certificateholder the necessary information under applicable law for preparation of such Holder’s federal and state income tax returns unless substantially similar information has been previously provided to such Certificateholder.
