          This DECLARATION OF TRUST, dated as of January 31, 2002 (this
"Declaration of Trust") between Allegheny Energy, Inc., a Maryland corporation
(the "Sponsor"), and Bank One Delaware, Inc., a national bank with its principle
office in the State of Delaware, as Delaware trustee (the "Delaware Trustee"),
and Regis F. Binder, as trustee (the "Administrative Trustee", and, together
with the Delaware Trustee, the "Trustees"). The Sponsor and the Trustees hereby
agree as follows:

          1.   The trust created hereby (the "Trust") shall be known as
"Allegheny Capital Trust II" in which name the Trustees, or the Sponsor to the
extent provided herein, may engage in the transactions contemplated hereby, make
and execute contracts, and sue and be sued.

          2.   The Sponsor hereby assigns, transfers, conveys and sets over to
the Trustees the sum of $100. The Administrative Trustee hereby acknowledges
receipt of such amount in trust from the Sponsor, which amount shall constitute
the initial trust estate. The Administrative Trustee hereby declares that it
will hold the trust estate in trust for the Sponsor. It is the intention of the
parties hereto that the Trust created hereby constitutes a business trust under
Chapter 38 of Title 12 of the Delaware Code, 12 Del. C. Section 3801 et seq.
(the "Business Trust 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 Secretary of State of the State
of Delaware in accordance with the provisions of the Business Trust Act.

          3.   The Sponsor 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 referred to therein. Prior
to the execution and delivery of such Amended and Restated Declaration of Trust,
(i) the Delaware Trustee shall not have any duty or obligation hereunder or with
respect to the trust estate, except as otherwise required by applicable law, and
(ii) the Administrative Trustee and the Sponsor shall take any action as may be
necessary to obtain prior to such execution and delivery any licenses, consents
or approvals required by applicable law or otherwise. Notwithstanding the
foregoing, the Trustees may take all actions deemed proper as are necessary to
effect the transactions contemplated herein.

          4.   The Sponsor hereby agrees to (i) reimburse the Delaware Trustee
for all reasonable expenses (including reasonable fees and expenses of counsel
and other experts), (ii) indemnify, defend and hold harmless the Delaware
Trustee and any of the officers, directors, employees and agents of the Delaware
Trustee (collectively, including

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 asserted at any time against such Indemnified Persons with respect to the
performance of this Declaration, the creation, operation, administration 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 Expenses to the extent such Expenses result from the willful
misconduct, bad faith or negligence of such Indemnified Person, and (iii)
advance to such Indemnified Person Expenses (including reasonable legal fees)
incurred by such Indemnified Person in defending any claim, demand, action, suit
or proceeding prior to the final disposition of such claim, demand, action, suit
or proceeding upon receipt by the Sponsor of an undertaking by or on behalf of
the Indemnified Person to repay such amount if it shall be determined that the
Indemnified Person is not entitled to be indemnified therefor under this
Section 4.
