corporation, as "Depositor," and The Bank of New York, a New York banking
corporation, The Bank of New York (Delaware), a Delaware banking corporation,
and David A. Brune, not in their individual capacities but solely as trustees

          1. The trust created hereby shall be known as "BGE Capital
Trust I," in which name the Trustees, or the Depositor to the extent provided
herein, may conduct the business of the Trust, make and execute contracts, and
sue and be sued.

          2. The Depositor hereby assigns, transfers, conveys and sets
over to the Trustees the sum of $10. The Trustees hereby acknowledge receipt of
such amount in trust from the Depositor, which amount shall constitute the
initial trust estate. The Trustees hereby declare that they will hold the trust
estate in trust for the Depositor. It is the intention of the parties hereto
that the Trust created hereby constitute a business trust under Chapter 38 of

Act"), and that this document constitutes the governing instrument of the Trust.
The Trustees are hereby authorized and directed to execute and file a
certificate of trust with the Delaware Secretary of State in accordance with the
provisions of the Business Trust Act.

          3. The Depositor and the Trustees will enter into an amended
and restated Declaration of Trust, satisfactory to each such party and
substantially in the form included as an exhibit to the 1933 Act Registration
Statement (as defined below), to provide for the contemplated operation of the
Trust created hereby and the issuance of the Preferred Securities and Common
Securities referred to therein. Prior to the execution and delivery of such
amended and restated Declaration of Trust, 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.

amendments thereto; (ii) to file with the New York Stock Exchange or any other
national stock exchange or The Nasdaq National Market (each, an "Exchange") and

on any of the Exchanges; (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 negotiate the terms of and to
execute, deliver and perform on behalf of the Trust a purchase agreement
relating to the Preferred Securities, in each case among the Trust, the
Depositor and the several Purchasers named therein, substantially in the form
included as an exhibit to the 1933 Act Registration Statement. In the event that
any filing referred to in clauses (i), (ii) and (iii) above is required by the
rules and regulations of the Commission, an Exchange or state securities or blue
sky laws, to be executed on behalf of the Trust by any of the Trustees, David A.
Brune, in his capacity as a Trustee of the Trust, is hereby authorized and
directed to join in any such filing and to execute on behalf of the Trust any
and all of the foregoing. In connection with all of the foregoing, the Depositor
hereby constitutes and appoints David A. Brune as its true and lawful
attorney-in-fact and agent, with full power of

                                      -2-

place and stead, in any and all capacities, to sign any and all amendments
including post-effective amendments) to the 1933 Act Registration Statement and
the 1934 Act Registration Statement and to file the same, with all exhibits
thereto, and other documents in connection therewith, with the Commission,
granting unto said attorney-in-fact and agent full power and authority to do
and perform each and every act and thing requisite and necessary to be done in
connection therewith, as fully to all intents and purposes as the Depositor
might or could do in person, hereby ratifying and confirming all that said
attorney-in-fact and agent or his substitute or substitutes, shall do or cause
to be done by virtue hereof.

          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 Depositor which may increase
or decrease the number of Trustees; provided, however, that to the extent
required by the Business Trust Act, one Trustee 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 Delaware law. Subject to the
foregoing, the Depositor is entitled to appoint or remove without cause any
Trustee at any time. Any Trustee may resign upon thirty (30) days' prior notice
to the Depositor.

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