amended; (ii) to file with the New York Stock Exchange or any other national

shall be necessary or desirable to cause the Preferred Securities to be listed
on any of the Exchanges; (iii) to negotiate and execute an underwriting

jurisdictions as the Sponsor, on behalf of the Trust, may deem necessary or
desirable and (v) to execute and deliver letters or documents to, or instruments
for filing with, a depository relating to the Preferred Securities of the Trust.

         It is hereby acknowledged and agreed that in connection with any
document referred to in clauses (i), (ii) and (iv) above, Bank One Delaware,
Inc. and Bank One Trust Company, N.A., in their capacities as trustees of the

Commission, the Exchanges or state securities or blue sky laws, and in such case
only to the extent so required.

         5. This Declaration may be executed in one or more counterparts.

         6. The number of Trustees initially shall be three (3) and thereafter
the number of Trustees shall be such number as shall be fixed from time to time
by a written instrument signed by the Sponsor which may increase or decrease the
number of Trustees; provided that, to the extent required by the Business Trust
Act, one Trustee shall be an entity that has its principal place of business in
the State of Delaware. Subject to the foregoing, the Sponsor is entitled to
appoint or remove without cause any Trustee at any time. The Trustees may resign
upon thirty days prior notice to the Sponsor.

         7. Bank One Delaware, Inc., in its capacity as trustee, shall not have
the powers or the duties of the Trustee set forth herein (except as may be
required under the Business trust Act) and shall be a Trustee hereunder for the
sole and limited purpose of fulfilling the requirements ofSection3807(a) of the
Business Trust Act.

         8. The Trust may be dissolved and terminated before the issuance of the
Preferred Securities at the election of the Sponsor.

         9. The Sponsor hereby agrees to (i) reimburse the Trustees for all
reasonable expenses (including reasonable fees and expenses of counsel and other
experts) and (ii) indemnify, defend and hold harmless the Trustees and any of
the officers, directors, employees and agents of the Trustees (the "Indemnified
Persons") from and against any and all losses, damages, liabilities, claims,
actions, suits, costs, expenses, disbursements (including the reasonable fees
and expenses of counsel), taxes and penalties of any kind and nature whatsoever
(collectively, "Expenses"), to the extent that such Expenses arise out of, or
are imposed upon, or are asserted at any time against, such Indemnified Persons
with respect to the performance of this
<PAGE>   3
Declaration, the creation, operation or termination of the Trust or the
transactions contemplated hereby; provided, however, that the Sponsor shall not
be required to indemnify any Indemnified Person for any Expenses which are a
result of the willful misconduct, bad faith or gross negligence of such
Indemnified Person.

         10. This Declaration shall be governed by and construed in accordance
with the laws of the State of Delaware.
