FROZEN AS OF DECEMBER 31, 2004

DOMINION RESOURCES, INC.

EXECUTIVE SUPPLEMENTAL RETIREMENT PLAN

Purpose

The Board of Directors of Virginia Electric and Power Company determined that adoption of the Executive Supplemental Retirement Plan would assist it in attracting and retaining those employees whose judgment, abilities and experience will contribute to its continued progress. On May 19, 1983, Virginia Electric and Power Company became a wholly-owned subsidiary of Dominion Resources, Inc. The Plan was amended to reflect the reorganization of Virginia Electric and Power Company and the Plan was adopted by Dominion Resources, Inc. The Plan was amended further, effective as of October 21, 1983, to require sixty (60) months of service to be eligible for retirement benefits and to assure Participants who have attained age fifty-five (55) and who have sixty (60) months of service with the Company, or who die or become Totally and Permanently Disabled, of their benefits, so long as they remain elected officers at the time of their separation from service. The Plan was amended further, effective as of September 1, 1996, to add a vesting schedule for Participants under age 55, to change the form and timing of benefit payments, and to coordinate payments with changes in a previously established trust. The Plan was again completely amended and restated effective July 8, 2002, subsequently amended and restated effective September 19, 2003, and restated effective December 17, 2004 to freeze the Plan.

Effective December 31, 2004, the Plan is closed to any new Participants and there shall be no new benefits accruing after that date. The terms and conditions of this Plan shall continue to apply with respect to all benefits accrued under this Plan and all Participants in this Plan on or before December 31, 2004.

The Plan is being restated with the intent that the restatement shall not constitute a material modification of the Plan for purposes of Section 885(d)(2) of Public Law No. 108-357, the American Jobs Creation Act of 2004. If any portion of this restatement is determined to be a material modification for that purpose, that portion of the restatement shall be null and void. All provisions of this restatement of the Plan shall be read and interpreted to be consistent with the intent of this paragraph. This Plan shall not be materially modified within the meaning of this section at any time in the future.

Participant’s completed months of service since becoming a Participant

In calculating months of service, partial months shall be disregarded. The actuarial equivalent of the benefit under this Section 3.1(d) shall be paid in a single lump sum payment.

Payment shall be made on the first day of the month following the Participant’s severance from employment with the Company or as soon thereafter as administratively practicable.

In no event shall an individual who was a Participant but who is not an officer of a designated employer at the time of such individual’s death, Retirement, Total and Permanent Disability, or other termination of employment with the Company be entitled to any benefit under the Plan. A Participant on authorized leave of absence from the Company shall not be deemed to have terminated employment or to lose the status of Participant solely as a result of such leave of absence.
