required by applicable law or otherwise. Notwithstanding the foregoing, the
Issuer Trustees may take all actions deemed proper as are necessary to effect
the transactions contemplated herein.

         4. The Sponsor, as the sponsor of the Issuer Trust, is hereby
authorized and appointed as the Issuer Trust's true and lawful attorney-in-fact

Securities Dealers (the "NASD"), and execute and verify on behalf of the Issuer
Trust a listing application and all other applications, statements,
certificates, agreements and other instruments, under seal or otherwise, as
shall be necessary or desirable, and do or cause to be done all such acts and
things in the name of and on behalf of the Issuer Trust to meet the requirements
of any such stock exchange, securities market or the NASD's Nasdaq National
Market, or to appear before the appropriate representatives of committees of any
such stock exchange or securities market, in order to cause the Preferred
Securities to be listed on any such stock exchange or securities market; (iii)
to file, execute and verify on behalf of the Issuer 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 or qualify the Preferred Securities for offer and sale
under the securities or "Blue Sky" laws of the various states and jurisdictions
of the United States or under any foreign laws or regulations as the Sponsor, on
behalf of the Issuer Trust, may deem necessary or desirable; and (iv) to
execute, deliver and perform on behalf of the Issuer Trust an underwriting
agreement with one or more underwriters relating to the offering of the
Preferred Securities of the Issuer Trust. In the event that any filing referred
to in clauses (i), (ii) or (iii) above is required by the rules and regulations
of the Commission, the New York Stock Exchange or such other exchanges or
securities markets, the NASD, or the securities or "Blue Sky" laws or foreign
laws or regulations to be executed on behalf of the Issuer Trust by the Issuer
Trustees, the Issuer Trustees are hereby authorized and directed to join in any
such filing and to execute on behalf of the Issuer Trust any and all of the
foregoing, it being understood that the Issuer Trustees shall not be required to
join in any such filing or execute on behalf of the Issuer Trust any such
document unless required by the rules and regulations of the Commission, the New
York Stock Exchange or such other exchange or securities markets, the NASD, or
the securities or "Blue Sky" laws or foreign laws or regulations.

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

         6. The number of trustees of the Issuer Trust initially shall each be
two and thereafter the number of trustees of the Issuer Trust 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 of the Issuer
Trust; provided, however, that, to the extent required by the Business Trust
Act, one trustee of the Issuer 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. Subject to the
foregoing, the Sponsor is entitled to appoint or remove without cause any
trustee of the Issuer Trust at any time. Any trustee of the Issuer Trust may
resign upon thirty days' prior notice to the Sponsor.








         7. Bank One Delaware, Inc., in its capacity as Issuer Trustee, shall
not have the powers or duties of the Issuer Trustees set forth herein (except as
may be required under the Business Trust Act) and shall be an Issuer Trustee
hereunder for the sole and limited purpose of fulfilling the requirements of
Section 3807(a) of the Business Trust Act.

         8. The Sponsor hereby agrees to indemnify, defend and hold harmless the
Issuer Trustees and any of the officers, directors, employees and agents of the
Issuer 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 Trust
Agreement, the creation, operation or termination of the Issuer 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.

         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).
