The Trustees are hereby authorized and directed to execute and file a certificate of trust with the Delaware Secretary of State substantially in the form attached hereto or in such other form as the Trustees may approve. 3.

Prior to the execution and delivery of such Amended and Restated Trust Agreement, the Trustees shall not have any duty or obligation hereunder or with respect to the trust estate, except as otherwise required by applicable law or as may be necessary to obtain prior to such execution and delivery any licenses, consents or approvals required by applicable law or otherwise. However, notwithstanding the foregoing, the Trustees may take all actions deemed proper as are necessary to effect the transactions contemplated herein. 4. The Depositor and the Trustees agree that, subsequent to the execution of this Trust Agreement and prior to the execution of the Amended and Restated Trust Agreement, the Depositor shall transfer an instrument (the "Control Certificate") which will establish in the holder of such Control Certificate, in addition to its rights, powers and duties hereunder, certain voting, administrative and appointment powers with respect to the Trust. Such voting, administrative and appointment powers shall be specified in the Amended and Restated Trust Agreement. 5. The Depositor, as the sponsor of the Trust, and the holder of the Control Certificate, as the case may be, acting singly or jointly, is hereby authorized, to cause the following actions to be taken (i) to file with the Securities and Exchange Commission (the "Commission"), on behalf of the Trust, (a) the 1933 Act Registration Statement including pre-effective or post-effective amendments to such Registration Statement, relating to the registration under the 1933 Act of the Preferred Securities of the Trust, (b) any preliminary prospectus or prospectus or supplement thereto relating to the Preferred Securities required to be filed pursuant to Rule 424 under the 1933 Act, and (c) a Registration Statement on Form 8-A or other appropriate form (the "1934 Act Registration Statement") (including all pre-effective and post-effective amendments thereto) relating to the registration of the Preferred Securities of the Trust under Section 12(b) of the Securities Exchange Act of 1934, as amended; (ii) to file with the New York Stock Exchange or any other exchange and execute on behalf of the Trust a listing application and all other applications, statements, certificates, agreements and other instruments as shall be necessary or desirable to cause the Preferred Securities to be listed on the New York Stock Exchange or any other exchange; (iii) to file and execute on behalf of the Trust such applications, reports, surety bonds, irrevocable consents, appointments of attorney for service of process and other papers and documents as shall be necessary or desirable to register the Preferred Securities under the securities or "Blue Sky" laws of such jurisdictions as the Depositor, on behalf of the Trust, may deem necessary or desirable; and (iv) to execute, deliver and perform on behalf of the Trust an underwriting agreement with respect to the Preferred Securities of the Trust. The Trustees further hereby ratify and approve all actions having previously been taken with respect to the foregoing. In the event that any filing referred to in clauses (i)-(iii) above is required by the rules and regulations of the Commission, the New York Stock Exchange or any other exchange or state securities or Blue Sky laws to be executed on behalf of the Trust by the Trustee, the Property Trustee and the Delaware Trustee, in their capacities as trustees of the Trust, are hereby authorized and directed to join in any such filing and to execute on behalf of the Trust any and all of the foregoing, it being understood that the Property Trustee and the Delaware Trustee in their capacities as trustees of the Trust shall not be required to join in any such filing or execute on behalf of the Trust any such document unless required by the rules and regulations of the Commission, the New York Stock Exchange or any other exchange or state securities or Blue Sky laws. 6.
