TERM OF EMPLOYMENT The term of the Executive's employment under this Agreement shall commence on January 3rd, 2001 and end on the third anniversary of such date (the "Term of Employment"). If the Company or the Executive does not deliver to the other party at least 60 days prior to the end of the three year term, written notice that the Term of Employment shall end on January 3, 2004, the Term of Employment shall automatically continue for an additional one-year period. At the end of such one year period, the Term of Employment shall automatically continue for successive one year terms unless either party delivers at least 60 days prior written notice that the Term of Employment shall end at the end of such one-year renewal period. 2. DUTIES (a) During the Term of Employment, the Executive shall serve as the Chief Executive Officer and, as provided in Section 2(b) below, a Director of the Company with such authority and duties as are generally associated with such position and as may be assigned to him from time to time by the Board of Directors of the Company that are consistent with such authority and duties. The Executive shall report to the Chairman of the Board of Directors of the Company, or someone or some body within the Board if there is no Chairman or if the Executive becomes the Chairman. (b) During the Term of Employment and except as provided in Section 2(c), the Executive shall devote his full business time and best efforts to the business and affairs of the Company. The Executive agrees to continue to serve during the Term of Employment as a Director and a member of any committee of the Board of Directors of the Company that the Board may designate. The Company agrees to use its commercially reasonable best efforts to cause the Executive to be elected and continued in office throughout the Term of Employment as a member of the Board of Directors of the Company and shall include him in the management slate for election as a Director of the Company at every stockholders' meeting of the Company at which his term as a Director would otherwise expire. -1- (c) Anything herein to the contrary notwithstanding, nothing in this Agreement shall preclude the Executive from (i) serving on the boards of directors of other corporations or the boards of a reasonable number of trade associations and/or charitable organizations, in each case subject to the prior approval of the Board of Directors of the Company (not to be unreasonably withheld), (ii) engaging in charitable activities and community affairs and (iii) managing his personal investments and affairs, provided that such activities do not interfere with the proper performance of his duties and responsibilities under this Agreement. The Company agrees that the Executive may continue to serve in all board positions disclosed to the Company prior to the date of this Agreement. 3. NO CONFLICT OF INTEREST The parties certify that the Executive has advised the Company of his professional and business relationship with Keir Kleinknecht. The business relationship is that the Executive was a member of the Board of Advisors for E-Goo Venture Fund, of which Mr. Kleinknecht was a managing partner. That business relationship is expected to continue in some form. The Company acknowledges that this relationship does not create a conflict of interest for the Executive or diminish in any respect the Executive's capacity to enter this Agreement or to perform the job and duties described in this Agreement. 4. COMPENSATION AND RELATED MATTERS (a) SALARY. During the Term of Employment, the Executive shall receive a base salary (the "Base Salary") at the rate of $260,000 per annum. Such Base Salary shall be payable semi-monthly in accordance with the Company's policies in effect from time to time. The Board of Directors from time to time may increase, but not decrease, the Base Salary. (b) BONUS. The Executive shall be eligible for a quarterly bonus in such amount as the Board of Directors may designate. Payment of any annual bonus shall be made at the same time that other senior-level executives receive their bonus but in no event later than fifteen days after the close of the period to which such bonus relates. (c) STOCK OPTIONS. To induce the Executive to enter into this Agreement, the Executive is hereby granted an option (the "Stock Option") by the Company to purchase shares of common stock, par value $0.05 per share, of the Company (the "Common Stock"). The Stock Option shall be memorialized in a separate stock option agreement, dated the date hereof, between the Company and the Executive. The Stock Options will be in two tranches. The first tranche of the Stock Option will be for 2,000,000 shares of Common Stock, and will have an exercise price per share equal to the closing market price per share of the Common Stock on the date of this Agreement. This tranche of the Stock Option shall vest over time as follows and be subject to earlier vesting as described below. Time vesting: 500,000 shares subject to the Stock Option shall vest on January 3, 2001, and 250,000 shares subject to the Stock Option shall vest thereafter on each six-month anniversary of such date. -2- Accelerated vesting of the number of shares indicated below, or such lesser amount as remains unvested at the time of the acceleration event, for any one-year period will occur as follows: NO. SHARES VESTING EVENT 250,000 Common Stock trades at $5/share for 10 consecutive trading days 250,000 Common Stock trades at $8/share for 10 consecutive trading days 250,000 Common Stock trades at $12/share for 10 consecutive trading days The price points designated above refer to the last reported sales price for the trading day. The second tranche of the Stock Option will be for 1,200,000 shares of Common Stock and will have an exercise price equal to the last reported sales price of the Common Stock on the date of this Agreement. Vesting of this tranche of the Stock Option will occur in equal quarterly increments over a three-year period commencing on January 3, 2001, e.g. 100,000 shares vest quarterly. As soon as reasonably practicable, the Company shall use its best efforts to register the shares underlying the Stock Options on Securities and Exchange Commission Form S-8, including the registration of any shares underlying Stock Options vested prior to the date of filing such Form S-8. Furthermore, the Company will permit the Executive to exercise some or all of his Stock Options described in this Section 4 prior to the full vesting of such Stock Options. If requested by the Executive, the Company will loan the Executive an amount equal to the total purchase price for the Stock Options included in this Section 4 which the Executive elects to exercise prior to vesting. Any such loan shall be a full recourse loan. In addition, the loan shall be secured by the shares of Common Stock of the Company purchased by the Executive with the proceeds thereof. Each such loan will bear interest at the market rate of interest as determined by the Company's independent accountants, or the maximum rate permissible by law (which under the laws of the Commonwealth of Virginia deemed to be the laws relating to permissible rates of interest on commercial loans), whichever is less, and shall become due and payable no later than January 3, 2004. The stock shall be held in escrow by the Company until vesting occurs at which time the Executive may chose to receive the stock in exchange for repayment of the pro-rata amount of the loan. The Executive may elect to file an election under Section 83(b) of the Code within thirty (30) days of the date of purchase of the shares. (d) EXPENSES. The Executive is authorized to incur reasonable expenses in carrying out his duties and responsibilities under this Agreement and the Company shall promptly reimburse him for all business expenses incurred in connection therewith, subject to documentation in accordance with the Company's policy. (e) EMPLOYEE BENEFITS. During the Term of Employment, the Executive shall be entitled to participate in or receive benefits under any and all employee benefit plans, programs and arrangements on terms no less favorable than those generally applicable to senior executives of the Company, subject to and on a basis consistent with the terms, conditions and overall administration of such employee benefit plans, programs and arrangements. The Executive shall also be eligible to participate in the Company's executive perquisites in accordance with the terms and provisions of the arrangements as in effect from time to time for the Company's senior executives. The Executive will receive a medical insurance coverage family plan as offered to other Executives. For the Term of Employment, said medical insurance coverage shall be for the maximum coverage available for said medical coverage. The Executive will receive life insurance coverage as comparable to that, which is offered to any other executive. (f) VACATION. The Executive shall be entitled to four weeks of paid vacation for each 12-month period during the Term of Employment, which shall be taken at such times and intervals as shall be determined by the Executive, subject to the reasonable business needs of the Company. The Executive shall also be entitled to the paid holidays and other paid leave set forth in the Company's policies. (g) PAYMENT UPON CHANGE OF CONTROL. In the event of a Change of Control of the Company, as defined in the Company's 1999 Long Term Incentive Plan, the Company shall issue to the Executive 400,000 shares of Common Stock, subject to proportionate adjustment in the case of dividends paid on the Common Stock in additional shares of Common Stock, and stock dividends and consolidations involving the Common Stock and equitable adjustment in the event of a reclassification or other reorganization affecting the Common Stock (or, if the Common Stock was modified, exchanged or converted in connection with such Change of Control, the cash, securities or other property that such 400,000 shares would represent at the time of the Change of Control if they had been modified, exchanged or converted in connection with such Change of Control). Such Common Stock will be registered by the Company (or its successor) with the Securities and Exchange Commission at the time of, or as soon as possible after, such issuance. (h) CASH PAYMENT IN CERTAIN CIRCUMSTANCES. In the event that the equity compensation to the Executive set forth in this Agreement is determined by the Company to require stockholder approval under applicable regulations of the Nasdaq Stock Market, then the Stock Options provided herein will be reduced to the largest number of Stock Options that could be issued to the Executive without such stockholder approval. In lieu of the Stock Options that are eliminated as a result of this provision, the Company will treat such Stock Options as stock appreciation rights having an exercise price equal to the exercise price of such Stock Options and, upon vesting and exercise thereof by the Executive, pay to the Executive, in cash, the difference between the exercise price of such stock appreciation rights and the closing market price of the Common Stock on the date the Executive exercises such rights. If any Stock Options are converted into stock appreciation rights, the Executive and the Company will enter into an agreement delineating such rights, which will be as comparable as practicable to the rights and responsibilities of the parties under the stock option agreement between the Executive and the Company. Notwithstanding the foregoing, if the equity compensation to the Executive set forth in this Agreement is determined by the Company to require stockholder approval under applicable regulations of the Nasdaq Stock Market, and such approval can be obtained at that time or the grant of such equity compensation can be ratified by stockholder approval, then in lieu of converting Stock Options into stock appreciation rights the Company will undertake its reasonable efforts to obtain such stockholder approval in order that the Stock Options will not be affected. -4- (i) DEDUCTIONS AND WITHHOLDINGS TAX GROSS-UP IN CERTAIN CIRCUMSTANCES. (i) All amounts payable or which become payable hereunder shall be subject to all deductions and withholding required by law. (ii) Notwithstanding the subsection (h)(i) above, if as a result of a Change of Control the Executive becomes subject to Section 280G of the Code (or any successor provision) which imposes an excise tax in respect of the issuance of any payment to the Executive under this Agreement, then the Company shall pay to the Executive, in cash at the time of such Change of Control, a "tax gross-up" equal to the amount of the Executive's tax liability resulting from such excise tax (including any tax on the amount so paid to cover this obligation calculated at the highest marginal federal and state income tax rates). (iii) The accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change of Control shall calculate the gross-up payment. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change of Control, the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder. (iv) The accounting firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the Company and Executive within fifteen (15) calendar days after the date on which Executive's right to a payment is triggered (if requested at that time by the Company or Executive) or such other time as requested by the Company or Executive. If the accounting firm determines that no excise tax is payable with respect to a payment, it shall furnish the Company and Executive with an opinion reasonably acceptable to Executive that no excise tax will be imposed with respect to such payment. Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon the Company and Executive. (v) The Company agrees to make reasonable efforts to obtain the requisite stockholder approval under Section 280G of the Code to avoid the imposition of an excise tax. (vi) If a transaction occurs which may invoke the provisions of Section 280G, the Executive shall cooperate with the Company to structure payments to the Executive in a manner to eliminate or minimize the effect upon the Company of Section 280G provided that such cooperation will not adversely affect the Executive. 5.
