1. INTRODUCTION



1.1 History and Purpose.    Allegheny Energy Service Corporation (the Company) previously established the Allegheny
Energy Supplemental Executive Retirement Plan (the Plan), an unfunded supplemental executive retirement plan. The purpose of the Plan is to provide special supplemental retirement benefits to a select group of senior executives of the
Company and its Affiliates (as defined below) in order to assist the Company and its Affiliates in attracting, motivating and retaining executives of superior ability, industry and loyalty. It is intended that the Plan shall at all times be
maintained on an unfunded basis for federal income tax purposes under the Internal Revenue Code of 1986, as amended, be administered as a top-hat plan for a select group of management or highly compensated employees, and be
exempt from the substantive requirements of the Employee Retirement Income Security Act of 1974, as amended.



1.2 Effective Date.    The Plan was originally established effective as of July 1, 1990. The Plan is hereby amended and
restated as of February 24, 2006, to reflect certain changes in the administration and operation of the Plan, to update the Plan for certain changes in applicable law, and to make certain other clarifying changes.

3.3 Eligibility Requirements.    Each
individual who satisfies the requirements of Section 3.1 or 3.2 shall be a Participant and shall be eligible to receive a benefit from the Plan upon satisfying the following age and service and other eligibility requirements:



(a) General Eligibility
Requirements.    A Participant who is actively employed by the Company or an Affiliate shall be eligible for a benefit from the Plan if (i) he retires when he has ten or more Years of Service, (ii) he retires on or
after attaining age 55, and (iii) he elects to commence payment of his Retirement Plan benefits as of the earliest date that such benefits are payable under the Retirement Plan.

(c) Termination for
Cause and Other Similar Circumstances.    Notwithstanding paragraph (a) hereof and any other provision of the Plan to the contrary,



3



---

(i) a Participant and his Beneficiaries shall not be eligible for a benefit from the Plan
if (A) a Participants employment with the Company or an Affiliate is terminated for Cause, or (B) the Committee determines that the facts and circumstances surrounding a Participants termination of employment (whether
characterized as a voluntary or involuntary termination) with the Company or an Affiliate constitute a basis for terminating the Participant for Cause, or



(ii) benefits being paid to a Participant or his Beneficiaries under the Plan shall immediately cease and all Plan benefits shall be
forfeited if (A) based upon material information that was not previously known to the Committee or the senior management of the Company or its Affiliates at the time of a Participants termination of employment, the Committee determines
that the facts and circumstances surrounding a Participants termination of employment (whether characterized as a voluntary or involuntary termination) with the Company or an Affiliate would have constituted a basis for terminating the
Participant for Cause, or (B) the Committee determines that the Participant materially breached the terms of any agreement with the Company or its Affiliates including, without limitation, the terms of any employment, separation, covenant not
to compete, confidentiality, non-solicitation agreement or other such agreement or covenant.



3.4 Termination of Participation.    The Committee (or the Chief Executive Officer acting in accordance with the authority delegated to him by the Committee) may terminate or limit the
participation of any Participant in the Plan for any reason at any time before the Participant or his Beneficiaries commences his benefit and otherwise satisfies the eligibility requirements of Section 3.3. This termination or limitation of
participation may include, without limitation, limiting the Years of Service and Compensation that may be taken into account for purposes of determining the amount of a Participants Accrued Benefit.



3.5 Additional Age and Service.    In its sole
discretion, the Committee (or the Chief Executive Officer acting in accordance with the authority delegated to him by the Committee) may establish an adjusted number of Years of Service and/or an adjusted age for a Participant. In determining the
amount of a Participants Accrued Benefit in accordance with Article IV, a Participants adjusted age and adjusted Years of Service shall be used as if they were his or her actual age and actual Years of Service. A Participants
adjusted Years of Service shall be taken into account for all purposes under the Plan including determinations as to a Participants eligibility to receive his Accrued Benefit and the amount of his Accrued Benefit. To be recognized under this
Section 3.5, adjusted Years of Service and/or an adjusted age for a Participant must be set forth in an employment agreement or other written agreement between the Participant and the Company or its Affiliates. For the sake of clarity, adjusted
Years of Service and/or an adjusted age granted to a Participant pursuant to an employment agreement or other written agreement entered into before the date of this amendment and restatement shall be effective under this Section 3.5.



4. RETIREMENT BENEFITS



4.1 Determination of Accrued Benefit.



(a) Accrued Benefit Formula.    A
Participants annual Accrued Benefit shall be equal to: (i) his Final Average Compensation multiplied by 2% multiplied by his Years of Service up to 25 years, plus (ii) his Final Average Compensation multiplied by 1% multiplied by his
Years of Service from 26 to 30 years, plus (iii) his Final Average Compensation multiplied by 1/2% multiplied by his Years of Service from 31 to 40 years, minus (iv) the Participants Retirement Plan Reduction, and minus (v) any
Other Supplemental Plan Reduction.



(b)
Limit on Amount of Accrued Benefit.    Notwithstanding the benefit formula in paragraph (a) and any other provision of the Plan to the contrary, a Participants Accrued Benefit calculated in accordance with
Section 4.1(a) shall not exceed 60% of the Participants Final Average Compensation, and such Accrued Benefit shall be reduced, if applicable, for early payment in accordance with the reduction factors described in Section 4.3.



4



---

(c) Assumptions.    To the extent that the Participants
Accrued Benefit is determined as of any date before a component benefit (that is, the benefit accrued under the Plan, the Retirement Plan benefit, or a benefit accrued under another supplemental pension plan) is payable on an unreduced basis, prior
to making such determination, each such component benefit(s) shall be reduced for early payment in accordance with the applicable reduction factors set forth in the plan documents for such component benefit(s). Further, to the extent that the
Participants Accrued Benefit is determined and payable before the date as of which the benefit accrued under the Retirement Plan or another supplemental pension plan is payable, the Accrued Benefit shall not be reduced by the Retirement Plan
Reduction and/or the Other Supplemental Plan Reduction until such time as amounts are first payable under such plan(s); provided, that once amounts first become payable under such plan(s), the Accrued Benefit shall be reduced by the Retirement Plan
Reduction and/or the Other Supplemental Plan Reduction, as the case may be, even if the Participant does not start receiving benefits under such other plan(s).



4.2 Normal Retirement Benefit.    A Participant shall be entitled to receive his Accrued Benefit upon retiring on or after
his Normal Retirement Date. Except to the extent of taking into account Years of Service and Compensation earned on or after a Participants Normal Retirement Date, a Participants Accrued Benefit shall not be adjusted or increased if the
Participant retires after his Normal Retirement Date.



4.3
Early Retirement Benefit.    A Participant shall be entitled to receive his Accrued Benefit upon retiring at an Early Retirement Date; provided, that such Accrued Benefit shall be subject to a reduction of 2% for each year
(or fractional portion thereof based upon the number of months for each year) that the Participant retires before his Normal Retirement Date.



4.4 Timing and Form of Payment for the Accrued Benefit.



(a) Timing of Payment.    A Participants Accrued Benefit shall be paid to him immediately upon his
retirement from the Company or an Affiliate.



(b) Form of Payment.    The Accrued Benefit of a Participant who is not married shall be paid to him in the form of a Single Life Annuity and the Accrued Benefit of a Participant who is married shall be paid to
him in the form of a Qualified Joint and Survivor Annuity that has the same actuarial value as the Single Life Annuity. In addition, a married Participant shall be eligible to elect to have his Accrued Benefit paid to him in the form of a Single
Life Annuity and any Participant shall be eligible to elect to have his Accrued Benefit paid to him in the form of a Contingent Annuitant Option that has the same actuarial value as a Single Life Annuity. Any such election to receive a Contingent
Annuitant Option (or, in the case of a married Participant, a Single Life Annuity) shall be made in accordance with the generally applicable terms of the Retirement Plan; provided, that (i) the Participant shall not be required to obtain the
consent of his spouse, and (ii) the Participant shall not be required to provide evidence of good health. The actuarial assumptions set forth in the Retirement Plan shall be used for purposes of converting the Single Life Annuity into other
payment forms.



4.5 Benefit
Computation.    A Participants retirement benefits shall be computed by the Committee or its designees under the terms of the Plan in effect as of the date of the Participants termination of employment with the
Company or an Affiliate and shall not be recomputed, increased or decreased after such termination, except for supplemental increases, if any, as may be granted by the Board of Directors.



5. DEATH BENEFITS



5.1 Death Before Commencement of Benefits.



(a) General.    In the event that a Participant dies before he retires and before he starts receiving payment
of his Accrued Benefit but after satisfying the eligibility requirements to receive death benefits as described in Article III, the Participants Surviving Spouse shall be eligible to receive a pre-retirement death benefit from the Plan. This
death benefit shall be determined in accordance with paragraph (b).



5



---

(b) Pre-Retirement Death Benefit.    If a Participant dies
while employed by the Company or an Affiliate and before attaining age 55, the Participants Surviving Spouse will receive the same benefit that would have been payable if the Participant had: (i) separated from service on the date of
death, (ii) survived until age 55, (iii) elected, in accordance with Article IV, to have benefits commence in the form of a Qualified Joint and Survivor Annuity, and (iv) died on the day after his 55th birthday. If a Participant
dies while employed by the Company or an Affiliate and after attaining age 55, the Participants Surviving Spouse will receive the same benefit that would have been payable if the Participant had retired with a Qualified Joint and Survivor
Annuity on the day before his death. The pre-retirement death benefit described in this paragraph shall start being paid to the Surviving Spouse as of the later of (i) the date that the Participant would have attained age 55, or (ii) the
date of the Participants death, unless the Surviving Spouse elects a later payment date.



5.2 Death After Commencement of Benefits.    If a Participant dies after payment of his Accrued Benefit has started, the death benefits, if any, payable under the Plan shall be determined by
the distribution form elected by the Participant before his death.



5.3 Designating a Beneficiary.    A Participant may designate a Beneficiary to receive any death benefit payable under Section 5.2 in accordance with the procedures established by the Committee or its
designees.



6. VESTING



A Participant shall have a vested interest in his Accrued Benefits upon the
satisfaction of the eligibility requirements of Article III. Notwithstanding the foregoing, a Participant who does not receive or does not continue to receive, as the case may be, benefits from the Plan pursuant to Section 3.3(c) shall forfeit
any vested interest in his Accrued Benefit.



7. FUNDED NATURE OF THE PLAN



The funds used for payment of benefits under this Plan
and the expenses incurred in the administration thereof shall, until such actual payment, continue to be a part of the general funds of the Company and no person other than the Company shall, by virtue of this Plan, have any interest in any such
funds. Nothing contained herein shall be deemed to create a trust of any kind or create any fiduciary relationship. To the extent that any person acquires a right to receive payments from the Company under this Plan, such right shall be no greater
than the right of any unsecured general creditor of the Company or its Affiliates.



8. ADMINISTRATION OF THE PLAN



8.1
Authority of the Committee.    The Plan shall be administered by the Committee. Subject to Section 8.2, the Committee shall have the exclusive authority and responsibility for all matters in connection with the
operation and administration of the Plan. This authority and responsibility shall include, without limitation, the full power and discretion to: (a) interpret and apply the Plans provisions, (b) establish procedures for administering
the Plan, (c) make decisions relating to an individuals eligibility to participate in the Plan, the amount of Plan benefits and factual determinations relating to the payment of benefits, (d) determine the time and form of benefit
payments, (e) compile and maintain all records necessary in connection with the Plan; (f) authorize the payment of all benefits and expenses of the Plan as they become payable under the Plan; (g) reduce or otherwise adjust amounts
payable under the Plan if payments are made in error; and (h) engage such legal, accounting, and other professional services as it may deem proper. The decisions of the Committee shall be made in the sole discretion of the Committee and shall
be final and binding upon all parties, including without limitation, the Company and its Affiliates, Participants and Beneficiaries.



8.2 Delegation of Authority.    The Committee, from time to time, may delegate to one or more of its members or to any other
person or persons or organizations any of its rights, powers, and duties with respect to the operation and administration of the Plan.



6



---

8.3 Compensation and Expenses.    The members of the Committee shall serve
without compensation, but all benefits payable under the Plan and all expenses properly incurred in the administration of the Plan, including all expenses properly incurred by the Committee in exercising its duties under the Plan, shall be borne by
the Company.



8.4 Liability of the Committee and Board;
Indemnification.    To the extent permitted by applicable law, no member of the Committee or the Board, or any authorized delegate thereof, shall be liable to any person for any action taken or omitted in connection with the
interpretation and administration of the Plan unless attributable to his own gross negligence, fraud or bad faith. The Company shall indemnify the members of the Committee and the Board and any authorized delegate thereof against any and all claims,
losses, damages and expenses, including counsel fees incurred by them and any liability, including any amounts paid in settlement with their approval, arising from their action or failure to act, except when the same is determined to be attributable
to their gross negligence, fraud or bad faith. The provisions of this paragraph are not intended to be exclusive, and nothing contained in this paragraph shall in any way limit indemnification provided to members of the Committee or the Board or any
authorized delegate thereof under the bylaws of the Company, by contract, by statute or otherwise.



9. AMENDMENTS AND TERMINATION



The Company (acting through the Board of Directors or its authorized delegate) reserves the right at any time and from time to time, to modify or amend, in whole or in part, any or all of the provisions of the Plan but no such amendment
shall adversely affect any Participants rights to his Accrued Benefit that is vested as determined in accordance with Section 6. Notwithstanding the foregoing, the Chief Executive Officer of the Company shall have the authority to adopt
such amendments to the Plan as may be necessary to comply with applicable law (including, without limitation, adopting retroactive or prospective amendments to comply with Code Section 409A), conform the terms of the Plan with its
administration, or as may otherwise be necessary to maintain the Plan; provided, that such amendments do not materially affect the benefits provided to Participants hereunder. To the extent permissible under Code Section 409A, the Company
(acting through the Board of Directors or its authorized delegate) shall have the right to terminate the Plan at any time but such action shall not adversely affect any Participants rights to his Accrued Benefits that is vested as determined
in accordance with Section 6.



10. CLAIMS PROCEDURES



Any Participant or other person claiming a benefit hereunder
(Claimant) may submit a written application to the Committee for payment of any benefit that may be due him under the Plan. Any such application shall set forth the nature of the claim and any additional information as the Committee may
reasonably request. Upon receipt of any such application, the Committee shall determine whether or not the Claimant is entitled to the benefit hereunder. If a claim is denied, in whole or in part, the Committee shall give written notice to any
Claimant of the denial of a claim for the commencement, continuation or calculation of amount of retirement benefits under the Plan. The notice shall be given within 90 days after receipt of the Claimants application, unless special
circumstances require an extension for processing the claim. In no event shall such extension exceed a period of 90 days from the end of such initial review period. The notice will be delivered to the Claimant or sent to the Claimants last
known address, and will include (a) the specific reason or reasons for the denial, (b) a specific reference or references to pertinent Plan provisions on which the denial is based, (c) a description of any additional material or
information for the Claimant to perfect the claim, which will indicate why such material or information is needed, (d) an explanation of the Plans claims review procedure, and the time limits applicable to such review periods, and
(e) a statement of the Claimants right to bring a civil action under Section 502(a) of ERISA following an adverse determination upon review.



7



---

If the Claimant wishes to appeal the claims denial, the Claimant or a duly authorized
representative must file a written request with the Committee for a review. This request must be made by the Claimant within 60 days after receiving notice of the claims denial. The Claimant or representative may review pertinent documents
relating to the claim and its denial, may submit issues and comments in writing to the Committee and may request a hearing. Within 60 days after receipt of such a request for review, the Committee shall reconsider the claim and, if the Claimant
shall have so requested and the Committee has granted such request, shall afford the Claimant or his representative a hearing before the Committee and make a decision on the merits of the claim. If circumstances require an extension of time for
processing the claim, the 60-day period may be extended, but in no event more than 120 days after the receipt of a request for review. In the event that the period of time is extended for the Claimants failure to submit information necessary
to decide the claim, the period for making the benefit determination shall be tolled from the date upon which the notification is sent to the Claimant and the date of the Claimants response. The decision on review will be in writing and will
be delivered to the Claimant or sent to the Claimants last known address. If the Claimants appeal is denied by the Committee, the denial will include (a) the specific reason or reasons for the denial, (b) a specific reference
or references to pertinent Plan provisions on which the denial is based, (c) a statement that the Claimant is entitled to receive, upon request, copies of all documents, records and other information relevant to the Claimants claim, and
(d) a statement of the Claimants right to bring a civil action under Section 502(a) of ERISA.



No court challenge to any Committee determination regarding a claim for benefits may be made by any Claimant until and unless he has exhausted the
procedure set forth above.
