Administration and Implementation of Plan 4.01 The Plan shall be administered by the Committee, which shall have full power to interpret and administer the Plan and full authority to act in selecting the Employees to whom Options 2 will be granted, in determining the number of Options to be granted to each such Employee and the terms and conditions of Options granted under the Plan. 4.02 The Committee's powers shall include, but not be limited to, the power: (a) to determine whether, to what extent and under what circumstances an Option may be granted and whether the Option is intended to be an incentive stock option (as defined in Section 422 of the Code) or a non-qualified stock option; (b) to determine whether, to what extent and under what circumstances an Option may be exercised; (c) to determine whether, to what extent and under what circumstances exceptions to the exercisability of an Option (including accelerating the exercisability) may be granted; (d) to condition an Option grant upon the attainment of specified performance goals; (e) to determine the effect, if any, of a change in control of the Company (including a merger of the Company into, a consolidation of the Company with, or an acquisition of the Company by, a person or entity or a liquidation of the Company) upon outstanding Options; (f) to establish an arrangement through registered broker-dealers whereby temporary financing may be made available to a Holder by the broker-dealer, under the rules and regulations of the Federal Reserve Board, for the purpose of assisting the Holder in the exercise of an Option; (g) to establish procedures, at the Committee's discretion, for a Holder (i) to have withheld from the total number of shares to be acquired upon the exercise of an Option that number of shares having a Fair Market Value, which, together with such cash as shall be paid in respect of fractional shares, shall equal the minimum statutory tax withholding obligation incurred by the Holder upon such exercise, or (ii) to exercise an Option by delivering a number of shares of Mature Common Stock already owned by such Holder having a Fair Market Value that shall equal the option exercise price and/or the tax withholding obligation incurred by the Holder upon such exercise; (h) to condition an Option grant upon such Employee's execution of non-compete, non-disclosure or similar arrangements in favor of the Company and/or its Subsidiaries and satisfactory in form and substance to the Committee; and (i) to establish a loan program to loan to a Holder who is still employed by the Company at the time of exercise an amount sufficient to satisfy the exercise price and/or tax obligation incurred by the Holder upon such exercise and thereafter loan promptly to such Holder such additional amounts sufficient to pay further withholding obligations as may be determined from time to time to be payable as a result of such exercise. Any amounts loaned to such Holder shall be 3 evidenced by a promissory note from such Holder on such terms as are mutually agreed to by the Committee and the Holder, provided, however, that such loan shall bear a market rate of interest and shall be full recourse. 4.03 The Committee shall have the power to adopt regulations for carrying out the Plan and to make changes in such regulations as it shall, from time to time, deem advisable. The Committee shall have the power unilaterally and without approval of a Holder to amend an existing Option in order to carry out the purposes of the Plan so long as such amendment does not take away any benefit granted to a Holder by the Option and as long as the amended Option comports with the terms of the Plan. Any interpretation by the Committee of the terms and provisions of the Plan and the administration thereof, and all action taken by the Committee, shall be final and binding on Holders. 5. Shares of Stock Subject to the Plan 5.01 Subject to adjustment as provided in Section 7, the total number of shares of Common Stock available for Options under the Plan shall be 500,000 shares, subject to increase by such number of shares as equals 5% of any and all Common Stock sold pursuant to the over-allotment option contained in the Underwriting Agreement between the Company and the several underwriters named therein relating to the offering of Common Stock registered pursuant to the Registration Statement. 5.02 Any shares issued by the Company through the assumption or substitution of outstanding grants from an acquired company shall not reduce the shares available for Options under the Plan. Any shares issued hereunder may consist, in whole or in part, of authorized and unissued shares or treasury shares. If any shares subject to any Option granted hereunder are forfeited or such Option otherwise terminates without the issuance of such shares or the payment of other consideration in lieu of such shares, the shares subject to such Option, to the extent of any such forfeiture or termination, shall again be available for grants of Options under the Plan. 5.03 No Employee may be granted Options for more than 100,000 shares of Common Stock during any calendar year (subject to adjustment as provided in Section 7). 4 6. Options Options give an Employee the right to purchase a specified number of shares of Common Stock from the Company for a specified time period at a fixed price. The grant of Options shall be subject to the following terms and conditions: 6.01 Option Grants: Options shall be evidenced by Option award certificates. Such certificates shall conform to the requirements of the Plan, and may contain such other provisions as the Committee shall deem advisable. 6.02 Option Price: The price per share at which Common Stock may be purchased upon exercise of an Option shall be determined by the Committee and shall be not less than the Fair Market Value of a share of Common Stock on the date of grant. 6.03 Term of Options: The Option award certificates shall specify when an Option may be exercisable and the terms and conditions applicable thereto. The Committee may waive any installment exercise or waiting period provisions, in whole or in part, at any time after the date of grant, based on such factors as the Committee, in its discretion, shall deem appropriate. The term of an Option shall in no event be greater than ten years from the date of grant. 6.04 Restriction on Transferability: No Option shall be transferable otherwise than by will or the laws of descent and distribution and, during the lifetime of the Holder, shall be exercisable only by the Holder. Upon the death of a Holder, the person to whom the rights have passed by will or by the laws of descent and distribution may exercise an Option only in accordance with this Section 6. 6.05 Payment of Option Price: The Option price of the shares of Common Stock acquired upon the exercise of an Option shall be paid in full in cash at the time of the exercise or, with the consent of the Committee, in whole or in part in Mature Common Stock or by a reduction in the number of shares of Common Stock otherwise required to be issued, with the shares of Common Stock in either case valued at Fair Market Value on the date of exercise. 6.06 Termination by Death: If a Holder's employment by the Company or a Subsidiary terminates by reason of death, any Option held by such Holder may thereafter be exercised, to the extent such Option was exercisable at the time of death or on such accelerated basis as the Committee may determine at or 5 after grant, by the legal representative of the Holder, until the expiration of the stated term of the Option or until such earlier time as the Committee may determine at the time the Option is granted. 6.07 Termination by Reason of Retirement or Disability: If a Holder's employment by the Company or a Subsidiary terminates by reason of disability (as determined by the Committee) or Retirement, any Option held by such Holder may thereafter be exercised by the Holder (or, where appropriate, the Holder's legal representative), to the extent it was exercisable at the time of such termination or on such accelerated basis as the Committee may determine at or after grant, until the expiration of the stated term of the Option or until such earlier time as the Committee may determine at the time the Option is granted. 6.08 Other Termination: If a Holder's employment by the Company or Subsidiary terminates for any reason other than death, disability or Retirement, the Option shall terminate 30 days after the date of such termination of employment. 6.09 Incentive Stock Options: To the extent that any Option does not qualify as an incentive stock option (whether because of its provisions or the time or manner of its exercise or otherwise), the portion of the Option which does not qualify as an incentive stock option will constitute a non-qualified stock option. 6.10 Post-Termination Exercise Periods: The Committee may, at any time, extend the post-termination exercise period applicable to a Holder, based on such factors as the Committee, in its discretion, shall deem appropriate, provided that the post-termination exercise period may not extend beyond the expiration of the stated term of the Option. 7. Adjustments Upon Changes in Capitalization In the event of a reorganization, recapitalization, stock split, reverse stock split, spin-off, split-off, split up, stock dividend, issuance of stock rights, combination of shares, merger, consolidation or any other change in the corporate structure of the Company affecting Common Stock, or any distribution to stockholders in respect of stock other than a cash dividend, the Committee shall make the adjustments in the number and kind of shares authorized by the Plan, the individual limit set forth in Section 5.03 and any adjustments to outstanding Options as it determines appropriate. No fractional shares of Common Stock shall be issued pursuant to such an adjustment. The Fair Market Value of any fractional shares resulting from adjustments pursuant to this section shall, where appropriate, be paid in cash to the Holder. If during the term of any Option granted hereunder the Company shall be, with the prior approval of a majority of the members of the 6 Board, merged into or consolidated with or otherwise combined with or acquired by a person or entity, or there is a liquidation of the Company, then at the election of the Committee, the Company may take such other action as the Committee shall determine to be reasonable under the circumstances to permit the Holder to realize the value of such Option, including without limitation paying cash to such Holder equal to the value of the Option or requiring the acquiring corporation to grant options or stock to such Holder having a value equal to the value of the Option. 8. Effective Date, Termination and Amendment The Plan shall become effective when it has been adopted by the Board and approved by the stockholders of the Company. The Plan shall remain in full force and effect until the earlier of 10 years from the date of its adoption by the Board, or the date it is terminated by the Board. The Board shall have the power to amend, suspend or terminate the Plan at any time, provided that no such amendment shall be made without stockholder approval which shall: 8.01 Increase (except as provided in Section 7) the total number of shares available for issuance pursuant to the Plan; 8.02 Change the provisions of this Section 8; or 8.03 Make any other change for which stockholder approval is required under rules or regulations promulgated under Section 16 of the 1934 Act or the Code. Termination of the Plan pursuant to this Section 8 shall not affect Options outstanding under the Plan at the time of termination. 9. General Provisions 9.01 Nothing contained in the Plan, or any Option granted pursuant to the Plan, shall confer upon any Employee any right with respect to continuance of employment by the Company or a Subsidiary, nor interfere in any way with the right of the Company or a Subsidiary to terminate the employment of any Employee at any time. 9.02 For purposes of this Plan, transfer of employment between the Company and its Subsidiaries shall not be deemed termination of employment. 9.03 Holders shall be responsible to make appropriate provision for all taxes required to be withheld in connection with any Option, the exercise thereof and the transfer of shares of Common Stock pursuant to this Plan. Such responsibility shall extend to all applicable Federal, state, local or foreign withholding taxes. In 7 the case of the exercise of Options, the Company shall, at the election of the Holder, but only with the consent of the Committee, have the right to repurchase from shares already held by the Holder, the number of shares of Mature Common Stock whose Fair Market Value equals the withholding tax obligation of such Holder or to make loans on the terms set forth in Section 4.02(i) to pay the applicable tax obligation incurred by the Holder upon such exercise. 9.04 The Company shall not be obligated to deliver certificates for Common Stock upon the exercise of an Option unless the Holder has made payment in full for such Common Stock as required by Sections 6.02 and 6.05 and has arranged for withholding of all taxes required by Section 9.03. 9.05 Without amending the Plan, Options may be granted to Employees who are foreign nationals or employed outside the United States or both, on such terms and conditions different from those specified in the Plan as may, in the judgment of the Committee, be necessary or desirable to further the purpose of the Plan. 9.06 Upon exercise of an Option, the Holder shall be required to make such representations and furnish such information as may, in the opinion of counsel for the Company, be appropriate to permit the Company to issue or transfer the shares of Common Stock in compliance with the provisions of applicable federal or state securities laws. The Company, in its discretion, may postpone the issuance and delivery of shares of Common Stock upon any exercise of an Option until completion of such registration or other qualification of such shares under any federal or state laws, or stock exchange listing, as the Company may consider appropriate. The Company is not obligated to register or qualify the shares of Common Stock issued pursuant to Options under federal or state securities laws and may refuse to issue such shares if neither registration nor exemption therefrom is practical. The Board may require that prior to the issuance or transfer of any shares of Common Stock upon exercise of an Option, the recipient enter into a written agreement to comply with any restrictions on subsequent disposition that the Board or the Company deems necessary or advisable under any applicable federal or state securities laws. Certificates representing the shares of Common Stock issued hereunder may be legended to reflect such restrictions. 9.07 To the extent that Federal laws (such as the 1934 Act, the Code or the Employee Retirement Income Security Act of 1974, as 8 amended) do not otherwise control, the Plan and all determinations made and actions taken pursuant hereto shall be governed by the law of Delaware and construed accordingly. 9.08 Upon the occurrence of a Change in Control, each Option then outstanding shall become immediately exercisable to the full extent of the shares of Common Stock subject thereto; provided, that (i) such Holder was employed by the Company at the time of such Change in Control and (ii) either (x) such Holder is employed by the Company on the first anniversary date of the Change in Control, (y) such Holder's employment is subsequently terminated by the Company other than for Cause during the one-year period following such Change in Control, or (z) such Holder voluntarily terminates such Holder's employment during the one-year period following such Change in Control as a result of a Constructive Termination. For purposes of this Plan, "Cause" means willful misconduct or dishonesty, or conviction of or failure to contest prosection for a felony, or excessive absenteeism unrelated to illness. For purposes of this Plan, a "Change in Control" shall be deemed to have occurred if any "person" or "group" (within the meaning of Sections 13(d) and 14(d)(2) of the 1934 Act) becomes the "beneficial owner" (as defined in Section 13(d)(3) under the 1934 Act) of securities of the Company representing more than 35 percent (35%) of the total aggregate voting power of the Company's then outstanding securities entitled to vote generally in the election of directors, and such person or group owns more aggregate voting power of the Company's then outstanding securities entitled to vote generally in the election of directors than any other person or group. For purposes of this Plan, "Constructive Termination" means when the Company (a) requires Holder to assume duties inconsistent with, or the Company makes a significant diminution or reduction in the nature or scope of Holder's authority or duties from, the authority or duties assigned to or held by Holder during the 30 days immediately prior to the Change in Control, or (b) materially reduces Holder's base salary, incentive compensation opportunities or fringe benefits or (c) relocates Holder's site of employment to a location more than 50 miles away from Holder's site of employment 30 days immediately prior to the Change in Control. Notwithstanding anything else contained in this Section 9.08, a Holder shall be eligible to exercise Options both before and after a Change in Control to the full extent otherwise permitted under the Plan. 9
