    6.3 Date of Termination. An Eligible Director's service as a director of the Company will, for purposes of the Plan, be deemed to have terminated on the date recorded on the personnel or other records of the Company, as determined by the Committee based upon such records.

7.  Rights of Eligible Directors; Transferability of Interests.

    7.1 Service as a Director. Nothing in the Plan will interfere with or limit in any way the right of the Company to terminate any Eligible Director at any time, and neither the Plan, nor the granting of an Incentive Award nor any other action taken pursuant to the Plan, will constitute or be evidence of any agreement or understanding, express or implied, that the Company will retain an Eligible Director for any period of time or at any particular rate of compensation.

    7.2 Rights as a Shareholder. An Eligible Director will have no rights as a shareholder unless and until a Stock Award is issued or an Option is exercised and the Eligible Director becomes the holder of record of such shares.

    7.3 Restrictions on Transfer of Interests. Except pursuant to testamentary will or the laws of descent and distribution or as otherwise expressly permitted by the Plan, no right or interest of any Eligible Director in an Option prior to the exercise of such Option will be assignable or transferable, or subjected to any lien, during the lifetime of the Eligible Director, either voluntarily or involuntarily, directly or indirectly, by operation of law or otherwise. An Eligible Director will, however, be entitled to designate a beneficiary to receive an Option upon such Eligible Director's death, and in the event of an Eligible Director's death, payment of any amounts due under the Plan will be made to, and exercise of any Options (to the extent permitted pursuant to Section 6 of the Plan) may be made by, the Eligible Director's legal representatives, heirs and legatees.

    7.4 Non-Exclusivity of the Plan.

8.  Securities Law and Other Restrictions.

    Notwithstanding any other provision of the Plan or any agreements entered into pursuant to the Plan, the Company will not be required to issue any shares of Common Stock under this Plan, and an Eligible Director may not sell, assign, transfer or otherwise dispose of shares of Common Stock issued in connection with an Incentive Award granted under the Plan, unless (a) there is in effect with respect to such shares a registration statement under the Securities Act and any applicable state securities laws or an exemption from such registration under the Securities Act and applicable state securities laws, and (b) there has been obtained any other consent, approval or permit from any other regulatory body which the Committee, in its sole discretion, deems necessary or advisable. The Company may condition such issuance, sale or transfer upon the receipt of any representations or agreements from the parties involved, and the placement of any legends on certificates representing shares of Common Stock, as may be deemed necessary or advisable by the Company in order to comply with such securities law or other restrictions.

9.  Plan Amendment, Modification and Termination.

    The Board may suspend or terminate the Plan or any portion thereof at any time, and may amend the Plan from time to time in such respects as the Board may deem advisable in order that Incentive Awards granted under the Plan will conform to any change in applicable laws or regulations or in any other respect the Board may deem to be in the best interests of the Company; provided, however, that (a) no amendments to the Plan will be effective without approval of the shareholders of the Company if shareholder approval of the amendment is then required pursuant to Rule 16b-3 under the Exchange Act or the rules of the National Association of Securities Dealers, Inc., and (b) to the extent prohibited by Rule 16b-3 of the Exchange Act, the Plan may not be amended more than once every six months. No termination, suspension or amendment of the Plan may adversely affect any outstanding Incentive Award without the consent of the affected Eligible Director; provided, however, that this sentence will not impair the right of the Committee to take whatever action it deems appropriate under Section 4.3 of the Plan.

10. Effective Date and Duration of the Plan.

    The Plan, as amended, is effective as of October 1, 1999, the date it was adopted by the Board.
