SECTION 1

INTRODUCTION AND PLAN HISTORY

1.01 Introduction. This Plan is maintained so as to strengthen the ability of the Corporation to attract and retain persons of outstanding competence upon which, in large measure, continued growth and profitability depend.

The Plan is intended to supplement any benefits that may be provided under any plans of the Corporation and its Subsidiaries, as they may be in effect from time to time, that are qualified under Section 401 of the Internal Revenue Code of 1986. The Corporation shall not be required to fund, in any way, any of the benefits provided under this Plan prior to the time payments become due to persons hereunder.

The Plan is intended to be an excess benefit plan within the meanings of Sections 3(36) and 201(7) of ERISA and an unfunded deferred compensation plan for a select group of management or highly compensated employees within the meanings of Sections 201 (2), 30l(a)(3) and 401(a)(4) of ERISA and shall be construed and interpreted accordingly.

1.02 Effective Date. The Plan was established January 1, 1983, and previously amended and restated as of January 1, 1989. The effective date of the amendment and restatement of the Plan as set forth herein is January 1, 2002, except as otherwise provided in the Plan or an Appendix attached to this document.

1.03 Plan Appendices and Exhibits. From time to time, the Corporation may adopt Exhibits to the Plan for the purpose of setting forth specific provisions of this Plan. In addition, the Corporation may from time to time adopt Appendices to this Plan for the purpose of providing documentation necessary to determine benefits under the Plan for certain employee groups. Each such Exhibit or Appendix shall be attached to and form a part of the Plan. Each such Exhibit or Appendix shall specify the Employing Unit to which it applies and shall supersede the provisions of the Plan document to the extent necessary to eliminate any inconsistencies between the Plan document and such Exhibit or Appendix.

1.04 Prior Provisions. The provisions of this Plan shall apply only to Employees who shall terminate active employment on or after the effective date of this Plan. Employees prior to January 1, 2002, who continue in active employment after January 1, 2002, shall continue to maintain their rights and benefits hereunder. The rights and benefits, if any, of an Employee who terminates active employment prior to January 1, 2002 (including Employees who were on layoff or were otherwise absent from service as of January 1, 2002 and who do not return to active employment prior to their respective severance from service dates), shall be determined in accordance with the provisions of the plans as they were in effect on the date of such termination from active employment except as specifically indicated herein.

SECTION 3

SUPPLEMENTAL BENEFITS DUE TO LIMITATIONS UNDER DEFINED BENEFIT PLANS

3.01 Participation. Eligibility for participation for any benefits provided under this Section 3 shall be extended to Employees covered under a benefit structure identified in Appendix A either who are members of a select group of management or highly compensated employees with benefits payable under such benefit structure restricted due to the limitations of Code Section 401(a)(17) or whose benefits payable thereunder are restricted due to Code Section 415 limitations.

Notwithstanding the preceding paragraph, an Employee shall not be eligible for a benefit under Section 3 if such Employee is eligible for benefits under an Appendix (other than Appendix A) or an agreement with the Corporation or its Subsidiaries where such Appendix or agreement provides benefits in lieu of benefits described in this Section 3 unless such Appendix or agreement provides otherwise.

However, calculation of this benefit shall reflect any restrictions and/or modifications described in Appendix A that may be applicable to the Participant.

3.03 Payment of Benefits.

Notwithstanding the preceding sentence and subject to Section 5.05, except as otherwise provided in Appendix D, if the Defined Benefit Plan(s) of which the Participant was a member permits a lump sum distribution option, a lump sum shall be available to such Participant under this Plan only if the Participant elects the lump sum distribution option prior to such Participant’s termination of employment.

If, after commencement of monthly benefit payments under the Plan, the amount of monthly payments to which the Participant is entitled under the Defined Benefit Plan is increased by reason of an increase in the limitations under Code Section 415 or 401(a)(17), the amount of the monthly payments to which he is entitled under the Plan will be decreased by the amount of monthly payment increase under the Defined Benefit Plan.

SECTION 4

SPECIAL SUPPLEMENTAL BENEFITS

4.01 Participation. Recognizing the need to make special retirement and other compensation or employee benefit provisions for certain Employees of Employing Units, the Corporation may, from time to time and in its best judgment, designate groups of select management or highly compensated employees as being eligible to receive additional benefits, substitute benefits, or more restrictive benefits than are found in Section 3 of the Plan. Any such Employees or groups of Employees shall be described in Appendices attached to this Plan or in other agreements with the Corporation or its Subsidiaries.

Such Employees shall not be eligible for a benefit under Section 3.02 to the extent such appendices or agreements provide for benefits in lieu of benefits described in Section 3 unless such Appendix or agreement provides otherwise. For those Employees with individual agreements, unless expressly provided in the agreement, the provisions of this Plan shall not apply to the benefit attributable to such agreement.

4.02 Benefits. Such benefits may be provided only to select management or highly compensated employees in such amounts as the Corporation determines are appropriate.

SECTION 5

MISCELLANEOUS PROVISIONS

5.01 Construction. In the construction of the Plan the masculine shall include the feminine and the singular shall include the plural in all cases where such meanings would be appropriate. This Plan shall be construed, governed, regulated, and administered according to the laws of the State of Virginia.

5.02 Employment. The Plan is not an employment contract. Participation in the Plan shall not give any Employee the right to be retained in the employ of the Corporation or its Subsidiaries, or upon dismissal or upon his voluntary termination of employment, to have any right, legal or equitable, under the Plan or any portion thereof, except as expressly granted by the Plan.

5.03 Non-alienability of Benefits. No benefit under the Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or charge; and any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, or charge the same shall be void; and no such benefit shall in any manner be liable for or subject to the debts, liabilities, engagements, or torts of the person entitled to such benefit, except as specifically provided in the Plan or pursuant to a Qualified Domestic Relations Order as described in Code Section 414(p).

5.04 Facility of Payment. If any recipient of benefits is, in the judgment of the Corporation, legally incapable of personally receiving and giving a valid receipt for any payment due him under the Plan, the Corporation may, unless and until claims shall have been made by a duly appointed guardian or committee of such person, make such payment or any part thereof to such person’s spouse, children, or other legal entity deemed by the Corporation to have incurred expenses or assumed responsibility for the expenses of such person. Any payment so made shall be a complete discharge of any liability under the Plan for such payment.

5.05 Discretionary Payment of Benefits. In any instance in which the Corporation in its sole and uncontrolled discretion believes such action to be in the best interest of the party entitled to receive any payment provided by this Plan, or to be in the best interests of the Corporation, amounts payable in installments pursuant to the provisions of this Plan may be paid in a single lump sum, the amount of which shall be of Actuarial Equivalent Value to the benefits for which the lump sum is to be substituted. It is intended by this Section 5.05 to vest the Corporation with full discretion to administer this Plan and to determine when and under what circumstances deviations which accelerate payments are necessary, desirable, or appropriate; and the Corporation shall have full power to authorize such deviations as regards each payee separately.

5.06 Obligation to Pay Amounts Hereunder.

5.07 Administration. To the extent consistent with the purposes and provisions of this Plan and as may be deemed necessary or advisable in the best judgment of the Corporation, the Plan shall be operated under the Administrative and General Provisions of the Defined Benefit Plans.

The Corporation shall make all determinations as to the right of any person to a benefit. Any denial by the Corporation of a claim for benefits under the Plan by a Participant shall be stated in writing by the Corporation and delivered or mailed to such individual. Such notice shall set forth the specific reasons for the denial, the specific reference to the provisions of the Plan on which the denial is based, a description of any additional material or information necessary to perfect the claim, an explanation of why such material or information is necessary, and the right to appeal a denial of the claim, for a full and fair review provided that a written request is made therefore within seventy-five (75) days after receipt of written notice of the denial of the claim, all in readily understandable language. Pertinent documents may be reviewed and issues and comments submitted in writing to the Corporation. If an appeal shall be made, the final decision shall be made within a period of sixty (60) days following receipt of the appeal, unless special circumstances require an extension of time for processing, in which case the decision shall be rendered as soon as possible, but not later than one hundred twenty (120) days after receipt of such appeal.

Unless otherwise provided by the Corporation, the Corporation’s Employee Benefit Appeals Committee shall rule in place of the Corporation and the Committee’s ruling shall be the final decision of the Corporation. Benefits shall be paid under the Plan only if the Corporation or Corporation’s Employee Benefit Appeals Committee in its sole discretion, determines that a Participant is entitled to them. There shall be no duplication of benefits between this Plan and its Appendices and any other plan or agreement with the Corporation or its Subsidiaries for the same period of service unless otherwise specifically stated in the Plan, Appendices or such other plan or agreement.
