PAYMENT FOR SHARES. The purchase price for shares of Common Stock to be acquired upon exercise of an option granted hereunder shall be paid in full, at the time of exercise, in cash, by certified check, bank draft or money order or by tendering to the Company shares of Common Stock then owned by the participant, duly endorsed for transfer or with duly executed stock power attached, which shares shall be valued at their Fair Market Value as of the date of such exercise and payment. Notwithstanding the foregoing, the option exercise price may be paid by delivery to the Company of a properly executed exercise notice, acceptable to the Company, together with irrevocable instructions to the participant's broker to deliver to the Company a sufficient amount of cash to pay the exercise price and any applicable income and employment withholding taxes, in accordance with a written agreement between the Company and the brokerage firm ("Cashless Exercise"). 9. WITHHOLDING TAXES. The Company shall have the right to withhold from a participant's compensation or require a participant to remit sufficient funds to satisfy applicable withholding for income and employment taxes upon the exercise of an option. 10. NON-ASSIGNABILITY. No option shall be transferable by a participant except by will or the laws of descent and distribution or, in the case of a Nonqualified Stock Option, pursuant to a qualified domestic relations order as defined by the Code or Title I of the Employee Retirement Income Security Act, or the rules thereunder. During the lifetime of a participant, an option shall be exercised only by the optionee. No transfer of an option shall be effective to bind the Company unless the Company shall have been furnished with written notice thereof and such evidence as the Company may deem necessary to establish the validity of the transfer and the acceptance by the transferee of the terms and conditions of the option. 11. TERMINATION OF EMPLOYMENT. Unless otherwise provided in the stock option agreement relating to a particular option: (a) if, prior to the date that such option shall first become exercisable, the participant's Employment shall be terminated, with or without cause, or by the act, death, Disability, or retirement of the participant, the participant's right to exercise the option shall terminate and all rights thereunder shall cease; and (b) if, on or after the date that such option shall first become exercisable, a participant's Employment shall be terminated for any reason other than death or Disability, the participant shall have the right, prior to the earlier of (i) the expiration of the option or (ii) three months after such termination of Employment, to exercise the option to the extent that it was exercisable and is unexercised on the date of such termination of Employment, subject to any other limitation on the exercise of the option in effect at the date of exercise; and (c) if, on or after the date that such option shall have become exercisable, the participant shall die or become Disabled while an Employee or 5 6 while such option remains exercisable, the participant or the executor or administrator of the estate of the participant (as the case may be), or the person or persons to whom the option shall have been transferred by will or by the laws of descent and distribution, shall have the right, prior to the earlier of (i) the expiration of the option or (ii) one year from the date of the participant's death or termination due to such Disability to exercise the option to the extent that it was exercisable and unexercised on the date of death, subject to any other limitation on exercise in effect at the date of exercise. The transfer of an Employee from one corporation to another among the Company, any Parent and any Subsidiary, or a leave of absence with the written consent of the Company, shall not constitute a termination of Employment for purposes of the Plan. 12. ADJUSTMENTS. In the event that the Committee shall determine that any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, issuance of warrants or other rights to purchase Common Stock, or other securities of the Company, or other similar corporate transaction or event affects the Common Stock such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Committee shall, in such manner as it may deem equitable, adjust any or all of (a) the number and type of shares of Common Stock which thereafter may be made the subject of options, (b) the number and type of shares of Common Stock subject to outstanding options, and (c) the exercise price with respect to any option, or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding option; provided, however, in each case, that with respect to the Incentive Stock Options no such adjustment shall be authorized to the extent that such authority would case the Plan to violate Section 422 of the Code or any successor provision thereto; and provided further, however, that the number of shares of Common Stock subject to any option shall always be a whole number. In the event of a Change of Control and under such other circumstances as the Committee may designate, options under the Plan shall be treated as the Committee may determine (including acceleration of vesting and settlements of options) at the time of grant or at a subsequent date as provided in the stock option agreement reflecting the grant of such options. 13. RIGHTS PRIOR TO ISSUANCE OF SHARES. No participant shall have any rights as a shareholder with respect to any shares covered by an option until the issuance of a stock certificate to the participant for such shares. No adjustment shall be made for dividends or other rights with respect to such shares for which the record date is prior to the date such certificate is issued. 6 7 14. TERMINATION AND AMENDMENT. The Board of Directors (the "Board") may terminate the Plan, or the granting of options under the Plan, at any time. No Incentive Stock Option shall be granted under the Plan ten years after adoption of the Plan by the Board or approval of the Plan by the Company's shareholders, whichever is earlier. Termination of the Plan shall not affect the rights of the holders of any options previously granted. The Board may amend or modify the Plan at any time and from time to time. No amendment, modification, or termination of the Plan shall in any manner affect any option granted under the Plan without the consent of the participant holding the option. 15. APPROVAL OF PLAN. The Plan shall be subject to the approval of the holders of at least a majority of the shares of Common Stock of the Company present and entitled to vote at a meeting of shareholders of the Company held within 12 months after adoption of the Plan by the Board. No option granted under the Plan may be exercised in whole or in part until the Plan has been approved by the shareholders as provided herein. If not approved by shareholders within such 12-month period, the Plan and any options granted hereunder shall become void and of no effect. 16. EFFECT ON EMPLOYMENT. Neither the adoption of the Plan nor the granting of any option pursuant to it shall be deemed to create any right in any individual to be retained as an Employee. 17. USE OF PROCEEDS. The proceeds received from the sale of Common Stock pursuant to exercises of options granted under the Plan will be used for general corporate purposes of the Company.
