6.2. Each Option agreement shall specify the period for which the Option thereunder is granted (which in no event shall exceed ten years from the date of the grant for any Option granted pursuant to Section 6.3(a) hereof, seven years from the date of grant for any Option granted pursuant to 6.3(b) hereof and ten years and one day from the date of grant for any Option designated by the Committee as a Non-Qualified Stock Option) and shall provide that the Option shall expire at the end of such period; provided, however, the term of each Option shall be subject to the power of the Committee, among other things, to accelerate or otherwise adjust the terms for exercise of Options pursuant to Section 4.7 hereof in the event of the occurrence of any of the events set forth therein.

6.3. The exercise price per share shall be determined by the Committee at the time any Option is granted; provided, however, that in no event shall the exercise price per share purchasable under a Non-Qualified Stock Option be less than 85% of the Fair Market Value of the Common Stock of the Corporation on the date the Option is granted, and, if the Option is an Incentive Stock Option, shall be determined as follows:

(a) For employees who do not own stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Corporation or of any Subsidiary, the Incentive Stock Option exercise price per share shall not be less than one hundred percent (100%) of Fair Market Value of the Common Stock of the Corporation on the date the Option is granted, as determined by the Committee.

(b) For employees who own stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Corporation or of any Subsidiary, the Incentive Stock Option exercise price per share shall not be less than one hundred ten percent (110%) of the Fair Market Value of the Common Stock of the Corporation on the date the Option is granted, as determined by the Committee.

6.4. The aggregate Fair Market Value (determined as of the time the Option is granted) of the Common Stock with respect to which an Incentive Stock Option under this Plan or any other plan of the Corporation or its Subsidiaries is exercisable for the first time by an Optionee during any calendar year shall not exceed $100,000.

6.5. An Option shall be exercisable at such time or times, and with respect to such minimum number of shares, as may be determined by the Corporation at the time of the grant. The Option agreement may require, if so determined by the Corporation, that no part of the Option may be exercised until the Optionee shall have remained in the employ of the Corporation or of a Subsidiary for such period after the date of the Option as the Corporation may specify. Notwithstanding the foregoing and subject to the discretionary acceleration rights of the Committee, an Option granted to a director, officer or 10% shareholders of the Corporation shall not be exercisable for a period of six (6) months unless the Option has been approved by the Board, the Committee or the shareholders of the Corporation.

6.6. The Corporation may prescribe the form of legend which shall be affixed to the stock certificate representing shares to be issued and the shares shall be subject to the provisions of any repurchase agreement or other agreement restricting the sale or transfer thereof. Such agreements or restrictions shall be noted on the certificate representing the shares to be issued.

7. Exercise of Option.

7.1. Each exercise of an Option granted hereunder, whether in whole or in part, shall be by written notice thereof, delivered to the Secretary of the Corporation (or such other person as he may designate). The notice shall state the number of shares with respect to which the Options are being exercised and shall be accompanied by payment in

full for the number of shares so designated. Shares shall be registered in the name of the Optionee unless the Optionee otherwise directs in his or her notice of election.

7.2. Payment shall be made to the Corporation either (i) in cash, including certified check, bank draft or money order, (ii) at the discretion of the Corporation, by delivering Common Stock of the Corporation already owned by the participant, (iii) at the discretion of the Corporation, by delivering a promissory note, containing such terms and conditions acceptable to the Corporation, for all or a portion of the purchase price of the shares so purchased, or a combination of (i), (ii) and (iii). With respect to (ii) the Fair Market Value of stock so delivered shall be determined as of the date immediately preceding the date of exercise.

7.3. Upon notification of the amount due and prior to, or concurrently with, the delivery to the Optionee of a certificate representing any shares purchased pursuant to the exercise of an Option, the Optionee shall promptly pay to the Corporation any amount necessary to satisfy applicable federal, state or local withholding tax requirements.

7.4. If the terms of an Option so permit, an Optionee, other than a member of the Committee, may elect by written notice to the Secretary of the Corporation (or such other person as he may designate), to satisfy the withholding tax requirements associated with the exercise of an Option by authorizing the Corporation to retain from the number of shares of Common Stock that would otherwise be deliverable to the Optionee that number of shares having an aggregate Fair Market Value on the Tax Date equal to the tax payable by the Optionee under Section 7.3. Any such election shall be in accordance with, and subject to, applicable tax and securities laws, and regulations and rulings and in the event shares are withheld, the amount withheld may not exceed the minimum required federal, state and FICA withholding amounts. Where shares are transferred to an Optionee prior to the Tax Date, the Optionee shall agree in any such election to surrender that number of shares having an aggregate Fair Market Value on the Tax Date equal to the tax payable by the Optionee under Section 7.3. In addition, any election to have shares withheld pursuant to this Section 7.4 will be irrevocable by the Optionee and will in any event be subject to the disapproval of the Committee.

8. Adjustments of Option Stock. In case the shares issuable upon exercise of any Option granted under the Plan at any time outstanding shall be subdivided into a greater or combined into a lesser number of shares (whether with or without par value), the number of shares purchasable upon exercise of such Option immediately prior thereto shall be adjusted so that the Optionee shall be entitled to receive a number of shares which he or she would have owned or have been entitled to receive after the happening of such event had such Option been exercised immediately prior to the happening of such subdivision or combination or any record date with respect thereto. An adjustment made pursuant to this paragraph shall become effective immediately after the effective date of such subdivision or combination retroactive to the record date, if any, for such subdivision or combination. The Option price (as such amount may have

7 theretofore been adjusted pursuant to the provisions hereof) shall be adjusted by multiplying the Option price immediately prior to the adjustment of the number of shares purchasable under the Option by a fraction, of which the numerator shall be the number of shares purchasable upon the exercise of the Option immediately prior to such adjustment, and of which the denominator shall be the number of shares so purchasable immediately thereafter. Substituted shares of stock shall be deemed shares under Section 3 of the Plan.

9. Assignments. Any Option granted under this Plan shall be exercisable only by the Optionee to whom granted during his or her lifetime and shall not be assignable or transferable otherwise than by will or by the laws of descent and distribution. Notwithstanding the foregoing, the Board or the Committee may, in its discretion, determine that an Option may be exercised by a person other than the Optionee and that an Option may be transferable based on he tax and federal securities law considerations then in effect for such Options.

10. Severance; Death; Disability. An Option shall terminate, and no rights thereunder may be exercised, if the person to whom it is granted ceases to be employed by the Corporation or by a Subsidiary except that:

10.1. If the employment of the Optionee is terminated by any reason other than his or her death or disability, the Optionee may at any time within not more than three months after termination of his or her employment, exercise his or her Option rights but only to the extent they were exercisable by the Optionee on the date of termination of his or her employment; provided, however, that if the employment is terminated by deliberate, willful or gross misconduct as determined by the Committee, all rights under the Option shall terminate and expire upon such termination.

10.2. If the Optionee dies while in the employ of the Corporation or a Subsidiary, or within not more than three months after termination of his or her employment, the Optionee’s rights under the Option may be exercised at any time within one year following such death by his or her personal representative or by the person or persons to whom such rights under the Option shall pass by will or by the laws of descent and distribution, but only to the extent they were exercisable by the Optionee on the date of death.

10.3. If the employment of the Optionee is terminated because of permanent disability, the Optionee, or his or her legal representative, may at any time within not more than one year after termination of his or her employment, exercise his or her Option rights but only to the extent they were exercisable by the Optionee on the date of termination of his or her employment.

10.4. Notwithstanding anything contained in Sections 10.1, 10.2 and 10.3 to the contrary, no Option rights shall be exercisable by anyone after the expiration of the term of the Option.

10.5. Transfers of employment between the Corporation and a Subsidiary, or between Subsidiaries, will not constitute termination of employment for purposes of any Option granted under this Plan. The Committee may specify in the terms and conditions of an Option whether any authorized leave of absence or absence for military or government service or for any other reasons will constitute a termination of employment for purposes of the Option and the Plan.

11. Rights of Participants. Neither the participant nor the personal representatives, heirs, or legatees of such participant shall be or have any of the rights or privileges of a shareholder of the Corporation in respect of any of the shares issuable upon the exercise of an Option granted under this Plan unless and until certificates representing such shares shall have been issued and delivered to the participant or to such personal representatives, heirs or legatees.

12. Securities Registration. If any law or regulation of the Securities and Exchange Commission or of any other body having jurisdiction shall require the Corporation or the participant to take any action in connection with the exercise of an Option, then notwithstanding any contrary provision of an Option agreement or this Plan, the date for exercise of such Option and the delivery of the shares purchased thereunder shall be deferred until the completion of the necessary action. In the event that the Corporation shall deem it necessary, the Corporation may condition the grant or exercise of an Option granted under this Plan upon the receipt of a satisfactory certificate that the Optionee is acquiring the Option or the shares obtained by exercise of the Option for investment purposes and not with the view or intent to resell or otherwise distribute such Option or shares. In such event, the stock certificate evidencing such shares shall bear a legend referring to applicable laws restricting transfer of such shares. In the event that the Corporation shall deem it necessary to register under the Securities Act of 1933, as amended, or any other applicable statute, any Options or any shares with respect to which an Option shall have been granted or exercised, then the participant shall cooperate with the Corporation and take such action as is necessary to permit registration or qualification of such Options or shares.

13. Duration and Amendment.

13.1. There is no express limitation upon the duration of the Plan, except for the requirement of the Code that all Incentive Stock Options must be granted within ten years from the date the Plan is approved by the shareholders.

13.2. The Board may terminate or may amend the Plan at any time, provided, however, that the Board may not, without approval of the shareholders of the Corporation, (i) increase the maximum number of shares as to which options may be granted under the Plan, (ii) permit the granting of Incentive Stock Options at less than 100% of Fair Market Value at time of grant, or (iii) permit any change which results in any repricing of any award or option heretofore granted hereunder.

14. Approval of Shareholders. This Plan expressly is subject to approval of holders of a majority of the outstanding shares of Common Stock of the Corporation, and if it is not so approved on or before one year after the date of adoption of this Plan by the Board, the Plan shall not come into effect, and any Options granted pursuant to this Plan shall be deemed canceled.

15. Conditions of Employment. The granting of an Option to a participant under this Plan who is an employee shall impose no obligation on the Corporation to continue the employment of any participant and shall not lessen or affect the right of the Corporation to terminate the employment of the participant.

16. Other Options. Nothing in the Plan will be construed to limit the authority of the Corporation to exercise its corporate rights and powers, including, by way of illustration and not by way of limitation, the right to grant options for proper corporate purposes otherwise than under the Plan to any employee or any other person, firm, corporation, association, or other entity, or to grant Options to, or assume Options of, any person for the acquisition by purchase, lease, merger, consolidation, or otherwise, of all or any part of the business and assets of any person, firm, corporation, association, or other entity.
