other exchange, or the NASD's Nasdaq National Market; (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

the New York Stock Exchange or other exchange, NASD, or state securities or
"blue sky" laws to be executed on behalf of the Trust by the Trustees, the
Trustees, in their capacity as trustees of the Trust, are hereby authorized to
join in any such filing and to execute on behalf of the Trust any and all of the
foregoing.

         5.   This Trust Agreement may be executed in one or more counterparts.

         6. The number of trustees of the Trust initially shall be two and
thereafter the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written instrument signed by the Depositor which
may increase or decrease the number of trustees of the Trust; provided, however,
that to the extent required by the Statutory Trust Act, one trustee of the Trust
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware and otherwise meets the requirements of applicable law.
Subject to the foregoing, the Depositor is entitled to appoint or remove without
cause any trustee of the Trust at any time. Any trustee of the Trust may resign

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 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 asserted at any time against such Indemnified Persons with
respect to the performance of this Trust Agreement, the creation, operation or
termination of the Trust or the transactions contemplated hereby; provided,
however, that the Depositor 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.

         8. The Trust may be dissolved and terminated before the issuance of the
preferred securities of the Trust at the election of the Depositor.

         9. This Trust Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware (without regard to conflict
of laws principles).
