No member of the Board or Committee shall be personally liable for any action or determination made in good faith with respect to the Plan or to any settlement of any dispute between a Participating Employee and the Corporation. Any decision made or action taken by the Committee or the Board with respect to the administration or interpretation of the Plan shall be conclusive and binding upon all persons. 4. ELIGIBILITY All U.S. employees of the Corporation and its Subsidiaries are eligible to participate in the Plan, except employees whose customary employment is twenty hours or less per week or who are employed for not more than five months in a calendar year. Each Eligible Employee may become a participant as of the first day of any calendar quarter by authorizing payroll deductions as provided in Section 6. No director of the Corporation or of any Subsidiary who is not an employee shall be eligible to participate in the Plan. Independent contractors of the Corporation or any Subsidiary are not eligible to participate in the Plan. 5. SHARES SUBJECT TO PLAN Subject to adjustment as provided in Section 14, the aggregate number of shares of Common Stock which may be issued and purchased under the Plan shall not exceed 1,000,000 shares of Common Stock. Shares needed to satisfy the needs of the Plan may be acquired from the Corporation or by purchase at the expense of the Corporation on the open market or in private transactions. 6. ELECTION TO PARTICIPATE Each Eligible Employee may become a Participating Employee effective on the first day of any calendar quarter coincident with or following the date such individual becomes an Eligible Employee by filing with the Board or Committee an Enrollment Form authorizing specified regular payroll deductions from such Eligible Employee's Cash Compensation. Such regular payroll deductions shall be subject to a minimum deduction of $25 per payroll period and a maximum deduction of 10 percent of Cash Compensation. All regular payroll deductions shall be credited to the Payroll Deduction Account that the Corporation has established in the name of the Participating Employee. 4 A Participating Employee may at any time withdraw from the Plan and cease to be a Participating Employee. An employee who has ceased to be a Participating Employee may not again become a Participating Employee until the first day of the next calendar quarter. A Participating Employee may, effective as of the first day of the following calendar quarter, increase or decrease the amount of such Participating Employee's payroll deductions by filing a new Enrollment Form. Enrollment Forms must be filed with the Corporation not less than fourteen days before the beginning of a calendar quarter to be effective for that calendar quarter unless a shorter period of time is prescribed by the Board or Committee. An Enrollment Form not filed within the prescribed filing period shall be effective the first day of the calendar quarter following the calendar quarter when it would otherwise become effective. An Enrollment Form, once filed, shall remain in effect for all subsequent payroll periods, unless the Participating Employee withdraws from the Plan or amends his or her Enrollment Form to increase or decrease the Employee's payroll deductions. 7. PURCHASE FROM PAYROLL DEDUCTION ACCOUNT Each Participating Employee having eligible funds in such Participating Employee's Payroll Deduction Account on an Investment Date shall be deemed, without any further action, to have purchased the number of whole shares which the eligible funds in such Participating Employee's Payroll Deduction Account could purchase at the Purchase Price. Any portion of the Participating Employee's Payroll Deduction Account that is not applied to the purchase of shares of Common Stock shall be held for the purchase of shares on the next Investment Date, unless the Participant has withdrawn from the Plan. In such event, any funds credited to the Participating Employee's Payroll Deduction Account shall be returned, without interest. 8. STOCK PURCHASES Shares of Common Stock shall be acquired for Participating Employees as of each Investment Date either from the Corporation or, if directed by the Board or Committee, by purchases on the open market or in private transactions using the payroll deduction amounts held by the Corporation for Participating Employees. If shares are purchased in one or more transactions on the open market or in private transactions at the direction of the Board or Committee, the Corporation will pay the difference between the Purchase Price and the price at which such shares are purchased for Participating Employees. As soon as practicable following each Investment Date, the Corporation shall direct the Corporation's transfer agent to credit on the books of the Corporation or deliver to each Participating Employee a stock certificate, the whole shares of stock acquired on such Investment Date by the Participating Employee. 9. LIMITATION ON PURCHASES No Participating Employee may purchase any Common Stock under this Plan and any other plan of the Corporation, and its Subsidiary corporations intended to qualify under Section 423 of the Code if the Fair Market Value of the purchase plus the Fair Market Value of all prior purchases by the Participating Employee under such plans (determined by reference to the Fair Market Value on each date of purchase) during any calendar year exceeds $25,000. A Participating Employee's Payroll Deduction Account may not be used to purchase Common Stock on any Investment Date to the extent that after such purchase the Participating Employee would own (or be considered as owning within the meaning of Section 424(d) of the Code) stock possessing 5 percent or more of the total combined voting power or value of all classes of stock of the Corporation or any Subsidiary. For this purpose, stock which the Participating Employee may purchase under any outstanding option shall be treated as owned by such Participating Employee. As of the first Investment Date on which this Section 9 limits a Participating Employee's ability to purchase Common Stock, the employee shall cease to be a Participating Employee. 5 10. TITLE TO SHARES The Corporation shall direct the Corporation's stock transfer agent to credit each Participating Employee with the whole shares acquired on each Investment Date. The Participating Employee may designate on his or her Enrollment Form whether shares shall be credited in the name of the Participating Employee or in the name of such Participating Employee jointly with a member of such Participating Employee's family, with right of survivorship. A Participating Employee who is a resident of a jurisdiction which does not recognize such a joint tenancy may direct that shares be credited in the Participating Employee's name as tenant in common with a member of the Participating Employee's family, without right of survivorship. 11. RIGHTS AS A SHAREHOLDER A Participating Employee shall have the right at any time to obtain a certificate for the whole shares of Common Stock credited to such Participating Employee or to direct that such shares be transferred to a broker designated by the Participating Employee to be held in street name. Subject to the provisions of Section 6, a Participating Employee shall have the right at any time to direct that any shares held in such Participating Employee's name be sold through a broker selected by the Participating Employee, and that the proceeds, less expenses of sale, be remitted to the Participating Employee. If a Participating Employee ceases to be such, the Participating Employee may elect to have the shares credited to such Participating Employee's name sold by a broker designated by the Participating Employee and the proceeds, after selling expenses, remitted, or the Participating Employee may elect to have a certificate for the whole shares of Common Stock credited to such Participating Employee's name forwarded to the Participating Employee. As a condition of participation in the Plan, each Participating Employee agrees to notify the Corporation in the event such individual sells or otherwise disposes of any of the shares of Common Stock acquired under this Plan within two years of the Investment Date on which such shares were purchased. 12. RETIREMENT, TERMINATION AND DEATH In the event of a Participating Employee's retirement or termination of employment, or if a Participating Employee ceases to be such, the amount in the Participating Employee's Payroll Deduction Account shall be refunded to the Participating Employee, and, unless otherwise elected, certificates will be issued for whole shares held in such Participating Employee's name. If a Participating Employee elects to have the shares sold, the Participating Employee will receive the proceeds of the sale, less selling expenses. In the event of death, the amount in the Participating Employee's Payroll Deduction Account and all shares in the Participating Employee's name shall be delivered to the beneficiary designated by the Participating Employee in a writing filed with the Corporation. If no beneficiary has been designated, or if the designated beneficiary does not survive the Participating Employee, such amount and all shares shall be delivered to the estate of the Participating Employee. 13. RIGHTS NOT TRANSFERABLE Rights under the Plan are not transferable by a Participating Employee except pursuant to a qualified domestic relations order, by will or by the laws of descent and distribution. All rights under the Plan are exercisable, during a Participating Employee's lifetime, only by such Participating Employee. 6 14. CHANGES IN CAPITALIZATION Subject to any required action by the stockholders, the number of shares covered by the Plan and the Purchase Price shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock of the Corporation resulting from a subdivision or consolidation of shares or the payment of a stock dividend (but only on the Common Stock) or any other increase or decrease in the number of such shares effected without receipt of consideration by the Corporation. In the event of a change of all of the Corporation's authorized Common Stock with par value into the same number of shares with a different par value or without par value, the Shares resulting from any such change shall be deemed to be Common Stock within the meaning of the Plan. To the extent that the foregoing adjustments relate to stock or securities of the Corporation, such adjustments shall be made by the Board or Committee, whose determination in that respect shall be final, binding and conclusive, provided that the Board or Committee shall make no adjustment that would cause the Plan to fail to continue to qualify as an employee stock purchase plan under Section 423 of the Code. Except as hereinbefore expressly provided in this Section 14, a Participating Employee shall have no rights (i) by reason of any subdivision or consolidation of shares of stock of any class, the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class, or (ii) by reason of any dissolution, liquidation, merger, or consolidation, spin-off of assets or stock of another corporation, or any issue by the Corporation of shares of stock of any class, nor shall any of these actions affect, or cause an adjustment to be made with respect to, the number or Purchase Price of shares subject to the Plan. The Plan shall not affect in any way the right or power of the Corporation (i) to make adjustments, reclassifications, reorganizations or changes of its capital or business structure, (ii) to merge or consolidate, (iii) to dissolve, liquidate, or sell or transfer all or any part of its business or assets or (iv) to issue any bonds, debentures, preferred or other preference stock ahead of or affecting the Common Stock. 15. AMENDMENT OF THE PLAN The Board of Directors may at any time, or from time to time, amend the Plan in any respect; provided, however, that the shareholders of the Corporation must approve any amendment that would materially (i) decrease the Purchase Price, (ii) increase the number of shares of Common Stock that may be issued under the Plan, or (iii) modify the requirements as to eligibility for participation in the Plan. 16. TERMINATION OF THE PLAN The Plan shall terminate on the earlier of: (a) the Investment Date that Participating Employees become entitled to purchase a number of shares greater than the number of reserved shares remaining available for purchase; or (b) April 1, 2008, or at any earlier date at the discretion of the Board of Directors. In the event that the Plan terminates under circumstances described in (a) above, reserved shares remaining as of the termination date shall be issued to Participating Employees on a pro rata basis. Upon termination of the Plan, all amounts in an employee's Payroll Deduction Account that are not used to purchase Common Stock will be refunded. 17. GOVERNING LAW The Plan shall be governed by, and construed in accordance with, the laws of the Commonwealth of Virginia. 7 18. EFFECTIVE DATE OF PLAN The Plan shall become effective on the date and at the time of the Corporation's 1998 annual meeting of shareholders, subject to the approval of the Plan on or before such date by a majority of the voting shares of Common Stock represented and entitled to vote.
