The period in which an Option may be exercised shall be determined by the Board on the date of grant of the Option, except that no Option shall be exercisable after the expiration of ten (10) years from the date of grant of the Option.  In the event of (a) the termination of the Optionee’s employment with the Company for reasons other than a Disability; (b) the termination of the Optionee’s employment with the Company due to a Disability; or (c) the death of the Optionee, the provisions of Section 7 hereof will govern the Option Exercise Period.





6.4  Vesting of Option.  The Board, in its sole discretion, will designate the vesting schedule of each individual Option that is to be granted;provided, however, that an Option will become immediately exercisable in full at the time of a Change of Control of the Company.





6.5           Restrictions on Transfer of Option.  Any Option granted under the Plan shall be exercisable during the Optionee’s lifetime only by the Optionee and shall not be assignable or transferable other than by will or by the laws of descent and distribution following the Optionee’s death.





6.6           Manner of Exercise.  Subject to the provisions of the Plan and the applicable Option Agreement, an Option may be exercised in whole at any time and in part from time to time at such times and upon such other terms and conditions as the Board shall determine.  A partial exercise of an Option shall not affect the right to exercise the Option from time to time in accordance with the Plan and the applicable Option Agreement with respect to the remaining shares of Stock subject to the Option.  In order to exercise an Option, an Optionee must give notice of exercise to the Secretary of the Company, specifying the Option to be exercised, the number of shares of Stock to be purchased pursuant to such exercise, and must be accompanied by payment in full for such shares.  Payment shall be made in cash or check payable to the Company for the full amount of the purchase price, unless otherwise provided in the Option Agreement.





7.             Effect of Termination of Employment, Disability or Death.  Except to the extent otherwise provided pursuant to Section 7.4 below, the following provisions shall govern the exercise of any Options held by an Optionee at the time the Optionee ceases to be an employee of the Company, suffers a Disability, or dies.





7.1           Termination of Employment.  In the event that the Optionee ceases to be an employee of the Company for any reason other than Disability or death, then the period during which each outstanding Option held by such Optionee is to remain exercisable shall be limited to the ninety (90) day period following the date of termination of employment.  Under no circumstances, however, shall any such Option be exercisable after the specified expiration date of the Option term.  Any outstanding Option may not be exercised in the aggregate for more than the number of vested shares for which the Option is exercisable on the date of the termination of








employment, and such Option shall terminate and cease to be outstanding with respect to any Option shares for which the Option is not at that time exercisable or in which the Optionee is not otherwise at that time vested.





7.2           Disability.  In the event that the Optionee ceases to be an employee of the Company by reason of a Disability, then the period during which each outstanding Option held by such Optionee is to remain exercisable shall be limited to a period of one (1) year following the date of termination of employment due to Disability.  Under no circumstances, however, shall any such Option be exercisable after the specified expiration date of the Option term as set forth in the Option Agreement.  Any outstanding Option may not be exercised in the aggregate for more than the number of vested shares for which the Option is exercisable on the date of the termination of employment due to Disability, and such Option shall terminate and cease to be outstanding with respect to any Option shares for which the Option is not at that time exercisable or in which the Optionee is not otherwise at that time vested.





7.3           Death. In the event that the Optionee dies while holding one or more outstanding Options, then the period during which each outstanding Option held by such Optionee is to remain exercisable shall be limited to a period of one (1) year following the date of the Optionee’s death.  During such limited period, the Option may be exercised by the personal representative of the Optionee’s estate or by the person or persons to whom the option is transferred pursuant to the Optionee’s will or in accordance with the laws of descent and distribution.

7.4           Extensions.  The Board shall have full power and authority to extend the period of time for which the Option is to remain exercisable under the circumstances set forth in Sections 7.1, 7.2 and 7.3 above to such greater period of time as the Board shall deem appropriate; provided, however, that in no event shall such Option be exercisable after the specified expiration date of the Option as set forth in the Option Agreement.





8.             Changes and Amendments to the Plan.  The Board shall have complete and exclusive power and authority to amend or modify the Plan in any respect, provided, however, that no such amendment or modification shall adversely affect the rights and obligations of an Optionee with respect to any Options at the time outstanding under the Plan without the consent of such Optionee.  Any such amendment or modification will be subject to the approval of the Company’s shareholders at or before the next annual meeting of shareholders for which the record date is after the date of such Board action if such shareholder approval is required by any federal or state law or regulation or the rules of any stock exchange or automated quotation system.

federal or state law or regulation or the rules of any stock exchange or automated quotation system, if it deems such shareholder approval to be desirable.

Certificates representing shares of Stock issued pursuant to the exercise of Options granted under the Plan will be subject to such stop-transfer orders and other restrictions as may be applicable under federal and state laws, regulations and rules, or the requirements of any securities exchange or automated quotation system, including the requirement that a legend or legends be placed on such certificates.





The Company shall not be required to sell or issue shares of its Stock under any Option if the sale or issuance would constitute a violation by the Optionee or the Company of any provisions of any state or federal law, rule or regulation.  In addition, in connection with the Securities Act of 1933, as amended, upon exercise of any Option, the Company shall not be required to issue such shares of Stock unless the Company has received evidence satisfactory to it to the effect that the Optionee will not transfer such shares except pursuant to a registration statement in effect under the Securities Act of 1933, or unless an opinion of counsel to the Company has been received to the effect that such registration is not required.





The Corporation may, but shall in no event be obligated to, register any securities covered hereby pursuant to the Securities Act of 1933; and in the event any shares are so registered, the Company may, in its discretion, remove any legend on certificates representing such shares of Stock.

9.3           Compliance with Section 16 of the Exchange Act.  The Board shall implement transactions under the Plan and administer the Plan in a manner that will ensure that each transaction involving an Optionee (other than a sale of shares acquired through the exercise of an Option) is exempt from liability under Rule 16b-3, except that an Optionee may be permitted to engage in a non-exempt transaction under the Plan if written notice is given to the Optionee regarding the non-exempt nature of such transaction.

9.8           No Employment.  Nothing in this Plan, including the granting of any Option shall impose upon the Company any obligation to employ the Optionee.  The right of the Company to terminate the employment of the Optionee shall not be diminished or affected by reason of the fact that an Option has been granted hereunder to the Optionee.





9.9           Investment Purpose.  The Optionee agrees that any shares of Stock subject to the Option granted under the Plan will be acquired for investment and not with any present intention to resell the same, and the Optionee further agrees to confirm such intention by an appropriate written assurances and certificates at the time of exercising an Option or any portion thereof.
