A deferred Annual Stock Retainer shall be credited in the form of Stock Units to the Director’s Stock Unit Account as of the day of the Company’s Annual Meeting. The number of Stock Units credited to the Stock Unit Account shall be equal to the number of shares of Company Stock elected to be deferred by the Director.

(ii) A Director may elect to defer all or a portion of his or her Annual Cash Retainer in increments of 10%. A Director may elect to have the deferred Annual Cash Retainer credited to his or her Deferred Cash Account or Stock Unit Account, or a combination of the two accounts.

(iii) The number of Stock Units credited to the Director’s Stock Unit Account attributable to a deferred Annual Cash Retainer shall be determined by dividing the amount of the deferred Annual Cash Retainer by the Fair Market Value of a share of Company Stock on the last trading day before the Company’s Annual Meeting and the amount of the deferred Annual Cash Retainer shall be rounded to the nearest whole share.

(iv) Deferrals of the Annual Cash Retainer in the form of Deferred Cash shall be credited to the Director’s Deferred Cash Account as of the day the Annual Cash Retainer would have been paid to the Director but for the deferral.

-4-

(iv) The number of Stock Units attributable to cash Meeting Fees shall be determined by dividing the amount of the deferred Meeting Fee by the Fair Market Value of a share of Company Stock on the last day of the month in which the meeting occurs and the Stock Units shall be credited to the Director’s Stock Unit Account as of that date and the amount of deferred cash Meeting Fees shall be rounded to the nearest whole share.

(v) Deferrals of cash Meeting Fees in the form of Deferred Cash shall be credited to the Director’s Deferred Cash Account as of the day the Meeting Fees would have been paid to the Director but for the deferral.

(d) Interest Credits to Deferred Cash Accounts. Interest is credited to a Deferred Cash Account on the last day of each calendar quarter of the Plan Year based on the balance in the Deferred Cash Account at the end of the preceding day. Interest will be credited at the annual rate established for the fixed rate fund used for various Dominion Resources, Inc. deferred compensation plans. Interest credits are accrued on a monthly basis through the end of the month preceding the month of distribution of a Deferred Cash Account.

(a) Any Eligible Director who was a participant in the Stock Accumulation Plan, who was not vested in whole or part in the Stock Accumulation Plan as of December 31, 2004, who ceased to participate in the Stock Accumulation Plan and who was a Director on January 1, 2005 received a Deferred Accumulation Benefit. The amount of the Deferred Accumulation Benefit was the number of Stock Units equal to (i) the number of Stock Units held in the Eligible Director’s accounts under the Stock Accumulation Plan as of December 31, 2004, divided by (ii) 17 and (iii) multiplied by the number of years the Director had been a member of the Company’s Board as of December 31, 2004.

(b) The Company credited the appropriate number of Stock Units as a result of the Deferred Accumulation Benefit to the Eligible Director’s Stock Unit Account as of January 1, 2005.

(a) All Stock Units credited to a Director’s Stock Unit Account shall be credited with hypothetical cash dividends equal to the cash dividends that are declared and paid on Company Stock. On each record date, the Company shall determine the amount of cash dividends to be paid per share of Company Stock. On the payment date of such dividend, the Company shall credit an equal amount of hypothetical cash dividends to each Stock Unit. The hypothetical cash dividends shall be converted into Stock Units by dividing the hypothetical cash dividends by the Fair Market Value of Company Stock for the last trading day preceding the day on which the Company pays dividends on its Common Stock. With respect to the March 20, 2005 dividend only, the number of Stock

-5-

Units credited to a Director’s Stock Unit Account shall be rounded to the nearest whole share. Hypothetical cash dividends shall continue to be credited to Stock Units and shall be converted into additional Stock Units as described in this subsection until all of the Stock Units in a Director’s Stock Unit Account have been distributed. The provisions of this subsection shall also apply to any distribution of Company Stock other than cash dividends or stock dividends, the market value of any such distributions to be determined by the Board.

(b) Stock Units and the Stock Unit Account may not be sold, assigned, transferred, disposed of, pledged, hypothecated or otherwise encumbered.

(a) Distribution Election. A Director may elect to receive his or her Deferred Cash Account and Stock Unit Account in a single lump sum payment or in ten (10) substantially equal annual installments. Except as permitted under any transition rule of Code section 409A for periods prior to January 1, 2009, a distribution election shall be made at the time the Director makes his or her initial Deferral Election and shall be irrevocable.

(b) Time of Distribution. Distribution of the Deferred Cash Account and Stock Unit Account shall be made (or in the case of installment payments, shall begin) as soon as administratively practicable after, but no later than 90 days after, the Director’s Separation from Service.

(c) Distribution upon Death of Director. In the event of a Director’s Separation from Service on account of death, payment shall be made to the Director’s Beneficiary in a single lump sum payment as soon as administratively practicable after, but no later than 90 days after, the death. If a Director dies after installment payments have commenced, the balance of the unpaid installment payments shall be paid in a single lump sum payment as soon as administratively practicable after, but no later than 90 days after, the Director’s death.

(d) Form of Payment. Payment of the Deferred Cash Account shall be made in cash. Payment of the Stock Unit Account shall be made in whole shares of Company Stock equal to the number of whole Stock Units in the Stock Unit Account. Payment for fractional shares shall be made in cash.

(a) With respect to the (i) deferred portion of the Annual Stock Retainer; (ii) the Annual Cash Retainer and Meeting Fees deferred into Stock Units; and (iii) Deferred Accumulation Benefits, the Company shall issue shares of Company Stock to a Trust equal to the number of Stock Units.

(b) The Corporate Secretary of the Company shall be the trustee of the Trust unless the Board designates another person or entity as trustee. The Trust shall secure the Company’s obligation to pay shares of Company Stock to the Director. The Trust and its

-6-

assets shall remain subject to the claims of the Company’s creditors. Any interest that the Director may be deemed to have in the Trust may not be sold, hypothecated or transferred (including, without limitation, transfer by gift), except by will or the laws of descent and distribution. Shares issued to the Trust shall be issued in the name of the trustee and the trustee shall maintain a separate account for each Director. The trustee shall invest all cash dividends on Company Stock in additional shares of Company Stock to be held in the separate account of the Director. The Director shall have the right to direct the trustee as to the voting of the number of shares of Company Stock equal to the number of Stock Units in the Director’s Stock Unit Account.

Notwithstanding any other provision in this Plan to the contrary, the time or schedule for any payment of the Deferred Cash Account or the Stock Unit Account under this Plan shall not be accelerated under any circumstances

The Plan also permits the award of Restricted Stock and Stock Options to Directors. The Board has the power and complete discretion to select Directors to receive such awards, and, under provisions consistent with this Section 11, to determine the terms and conditions, the nature of the award and the number of shares to be allocated as part of each award for each Director.

(a) The Board shall establish as to each award of Restricted Stock, the terms and conditions upon which the restrictions shall lapse. Shares of Restricted Stock may not be sold, assigned, transferred, pledged, hypothecated, or otherwise encumbered or disposed of until the restrictions on such shares as set forth in the restricted stock agreement have lapsed. Whenever the Board deems it appropriate to grant Restricted Stock to a Director, notice shall be given to the Director stating the number of shares of Restricted Stock granted and the terms and conditions to which the Restricted Stock is subject. This notice shall become a grant agreement between the Company and the Director. Upon the award of Restricted Stock, the Director shall have all the rights of a shareholder with respect to such shares of Restricted Stock, including, but not limited to, the right to vote such shares of Restricted Stock and the right to receive all dividends and other distributions paid thereon. Certificates representing Restricted Stock shall be held by the Company until the restrictions lapse and the Director shall provide the Company with appropriate stock powers endorsed in blank.

(b) Whenever the Board deems it appropriate to grant Options, notice shall be given to the Director stating the number of shares for which Options are granted, Option price per share, and the conditions to which the grant and exercise of the Options are subject. This notice shall become a stock option agreement. The exercise price of shares of Company Stock covered by a Stock Option shall be not less than 100% of the Fair Market Value of Company Stock on the day prior to the grant of the Stock Option. Stock Options may be exercised in whole or in part at such time as may be specified in the stock option agreement; provided that no Stock Option may be exercised after the expiration of eight (8) years from the date of the grant of the Stock Option.

In the event of a stock dividend, stock split or combination of shares, recapitalization or merger in which the Company is the surviving corporation or other change in the Company’s capital stock, the number and kind of shares of Company Stock to be subject to the Plan and the maximum number of shares which are authorized for distribution under the Plan shall be appropriately adjusted by the Board or a Committee of the Board, whose determination shall be binding on all persons.

The Board shall administer, construe and interpret the Plan. Any decision of the Board with respect to the Plan shall be final, conclusive and binding upon all Directors. The Board may act by a majority of its members. The Board may authorize any member of the Board or any officer of the Company to execute and deliver documents on behalf of the Board. The Board may consult with counsel, who may be counsel to the Company, and shall not incur any liability for action taken in good faith in reliance upon the advice of counsel. The Corporate Secretary of the Company shall be authorized to take or cause to be taken such actions of a ministerial nature as necessary to effectuate the intent and purposes of the Plan, including issuing Company Stock for the Plan, maintaining records of the Directors accounts, and arranging for distributions of such accounts in accordance with this Plan document. The Board shall interpret this Plan for all purposes in accordance with Code section 409A and the regulations thereunder.

The Plan shall continue until terminated at any time by action of the Board or until there are no remaining shares available for the Plan under Section 4. Any termination of the Plan by the Board shall not alter or impair any of the rights or obligations for any benefit previously deferred under the Plan.

The Board may suspend or terminate the Plan or revise or amend the Plan in any respect; provided, any amendment or termination of the Plan shall not adversely affect a Director with respect to any benefit previously deferred under the Plan.

The Plan shall not constitute or be evidence of any agreement or understanding, express or implied, that the Company will retain any person as a director for any period of time.

A Director may designate in writing delivered to the Company’s Corporate Secretary, one or more beneficiaries (which may include a trust) to receive any distributions under the Plan after the death of the Director. If a Director fails to designate a beneficiary, or no designated beneficiary survives the Director, any payments to be made with respect to the Director after death shall be made to the personal representative of the Director’s estate.

All notices and other communications required or permitted to be given under this Plan shall be in writing and shall be deemed to have been duly given if delivered personally or mailed first class, postage prepaid, as follows: (a) if to the Company - at its principal business address to the attention of the Corporate Secretary; (b) if to any Director - at the last address of the Director known to the sender at the time the notice or other communication is sent.
