Subject to the provisions of Section 10 of the Plan, the maximum aggregate number of Shares which may be optioned and sold under the Plan is two hundred fifty thousand (250,000) Shares (the “Pool”) of Common Stock. The Shares may be authorized but unissued, or reacquired Common Stock.

If an Option should expire or become unexercisable for any reason without having been exercised in full, the unpurchased Shares that were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan (unless the Plan has terminated). Shares that have actually been issued under the Plan shall not be returned to the Plan and shall not become available for future distribution under the Plan.

4. Administration of and Grants of Options under the Plan.

(a) Procedure for Grants. Except as otherwise required herein, the Plan shall be administered by the Board. All grants of options to Outside Directors under this Plan shall be automatic and non-discretionary and shall be made strictly in accordance with the following provisions:

(i) No person shall have any discretion to select which Outside Directors shall be granted Options or to determine the number of shares to be covered by Options granted to Outside Directors; provided, however, that nothing in this Plan shall be construed to prevent an Outside Director from declining to receive an Option under this Plan.

-2-

(ii) Each Outside Director shall be automatically granted an Option to purchase twenty thousand (20,000) Shares on the date on which such person first becomes a Director, whether through election by the shareholders of the Company or appointment by the Board to fill a vacancy;

(iii) On the second business day of each fiscal quarter during the term of this Director Plan, each Outside Director shall automatically receive an Option to purchase two thousand five hundred (2,500) Shares, provided that he or she has been an Outside Director for at least six (6) months on such dates;

(iv) The terms of an Option granted pursuant to this Section shall be as follows:

(A) the term of the Option shall be five (5) years;

(B) except as provided in Section 10 of this Plan, the Option shall be exercisable only while the Outside Director remains a director;

(C) the exercise price per share of Common Stock shall be 100% of the Fair Market Value on the date of grant of the Option;

(D) the Option shall become exercisable in installments cumulatively with respect to thirty-three and one-third (33-1/3%) of the Optioned Stock one year after the date of grant and as to an additional thirty-three and one-third (33-1/3%) of the Optioned Stock each year thereafter, so that one hundred percent (100%) of the Optioned Stock shall be exercisable three years after the date of grant; provided, however, that in no event shall any Option be exercisable prior to obtaining shareholder approval of the Plan.

(v) In the event that any Option granted under the Plan would cause the number of Shares subject to outstanding Options plus the number of Shares previously purchased upon exercise of Options to exceed the Pool, then each such automatic grant shall be for that number of Shares determined by dividing the total number of Shares remaining available for grant by the number of Outside Directors on the automatic grant date. No further grants shall be made until such time, if any, as additional Shares become available for grant under the Plan through action of the shareholders to increase the number of Shares which may be issued under the Plan or through cancellation or expiration of Options previously granted hereunder.

(b) Powers of the Board. Subject to the provisions and restrictions of the Plan, the Board shall have the authority, in its discretion: (i) to determine, upon review of relevant information and in accordance with y Section 2(i) of the Plan, the Fair Market Value of the Common Stock; (ii) to interpret the Plan; (iii) to prescribe, amend and rescind rules and regulations relating

-3-

to the Plan; (iv) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option previously granted hereunder; and (v) to make all other determinations deemed necessary or advisable for the administration of the Plan.

(c) Effect of Board’s Decision. All decisions, determinations and interpretations of the Board shall be final.

5. Eligibility. Options may be granted only to Outside Directors. All Options shall be automatically granted in accordance with the terms set forth in Section 4(b) hereof. An Outside Director who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options in accordance with such provisions.

The Plan shall not confer upon any Optionee any right with respect to continuation of service as a Director or nomination to serve as a Director, nor shall it interfere in any way with any rights which the Director or the Company may have to terminate his directorship at any time.

6. Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the shareholders of the Company as described in Section 1616 of the Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 11 of the Plan.

7. Exercise Price and Consideration.

(a) Exercise Price. The per Share exercise price for Optioned Stock shall be 100% of the Fair Market Value per Share on the date of grant of the Option.

(b) Form of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Board and may consist entirely of (i) cash, (ii) check, (iii) promissory note, (iv) other shares which have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised and which, in the case of Shares acquired upon exercise of an option, have been owned by the Optionee for more than twelve (12) months on the date of surrender, (v) delivery of a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds required to pay the exercise price, (vi) delivery of an irrevocable subscription agreement for the Shares which irrevocably obligates the Optionee to take and pay for the Shares not more than twelve (12) months after the date of delivery of the subscription agreement, (vii) any combination of the foregoing methods of payment, or (viii) such other consideration and method of payment for the issuance of Shares to the extent permitted under applicable law.

8. Exercise of Option.

(a) Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be exercisable at such times as are set forth in Section 4 hereof; provided, however, that no Options shall be exercisable until shareholder approval of the Plan in accordance with Section 16 hereof has been obtained.

-4-

An Option may not be exercised for a fraction of a Share.

An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may consist of any consideration and method of payment allowable under Section 7(b) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. A share certificate for the number of Shares so acquired shall be issued to the Optionee as soon as practicable after exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 10 of the Plan.

Exercise of an Option in any manner shall result in a decrease in the number of Shares that thereafter may be available, both for purposes of the Plan and for sale under the- Option, by the number of Shares as to which the Option is exercised.

(b) Termination of Continuous Status as a Director. In the event an Optionee’s Continuous Status as a Director terminates (other than upon the Optionee’s death or total and permanent disability (as defined in Section 22(e)(3) of the Code)), the Optionee may exercise his or her Option, but only within three (3) months from the date of such termination, and only to the extent that the Optionee was entitled to exercise it at the date of such termination (but in no event later than the expiration of its five (5) year term). To the extent that the Optionee was not entitled to exercise an Option at the date of such termination, and to the extent that the Optionee does not exercise such Option (to the extent otherwise so entitled) within the time specified herein, the Option shall terminate.

(c) Disability of Optionee. In the event Optionee’s Continuous Status as a Director terminates as a result of total and permanent disability (as defined in Section 22(e)(3) of the Code), the Optionee may exercise his or her Option, but only within twelve (12) months from the date of such termination, and only to the extent that the Optionee was entitled to exercise it at the date of such termination (but in no event later than the expiration of its five (5) year term). To the extent that the Optionee was not entitled to exercise an Option at the date of termination, or if he or she does not exercise such Option (to the extent otherwise so entitled) within the time specified herein, the Option shall terminate.

(d) Death of Optionee. In the event of an Optionee’s death, the Optionee’s estate or a person who acquired the right to exercise the Option by bequest or inheritance may exercise the Option, but only within twelve (12) months following the date of death, and only to the extent that the Optionee was entitled to exercise it at the date of death (but in no event later than the expiration of its five (5) year term). To the extent that the Optionee was not entitled to exercise an Option at the date of death, and to the extent that the Optionee’s estate or a person who acquired the right to exercise such Option does not exercise such Option (to the extent otherwise so entitled) within the time specified herein, the Option shall terminate.

-5-

9. Non-Transferability of Options. The Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee.

10. Adjustments.

(a) Changes in Capitalization. In the event that the stock of the Company is changed by reason of any stock split, reverse stock split, recapitalization, or other change in the capital structure of the Company, or converted into or exchanged for other securities as a result of any merger, consolidation or reorganization, or in the event that the outstanding number of shares of stock of the Company is increased through payment of a stock dividend, appropriate proportionate adjustments shall be made in the number and class of shares of stock subject to the Plan, the number and class of shares subject to the Plan, the number and class of share subject to any Option outstanding under the Plan, and the exercise price of any such outstanding Option; provided, however, that the Company shall not be required to issue fractional shares as a result of any such adjustment. Any such adjustment shall be made upon approval by the Board, whose determination shall be conclusive. If there is any other change in the number or type of the outstanding shares of stock of the Company, or of any other security into which such stock shall have been changed or for which it shall have been exchanged, and if the Board in its sole discretion determines that such change equitably requires an adjustment in the Options then outstanding under the Plan, such adjustment shall be made in accordance with the determination of the Board. No adjustments shall be required by reason of the issuance or sale by the Company for cash or other consideration of additional shares of its stock or securities convertible into or exchangeable for shares of its stock.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, to the extent that an Option has not been previously exercised, it shall terminate immediately prior to the consummation of such proposed action.

(c) Merger or Asset Sale. In the event of a merger of the Company with or into another corporation which does not constitute a “Change of Control” (as defined in Section (e)) or the sale of substantially all of the assets of the Company, outstanding Options may be assumed or equivalent options may be substituted by the successor corporation or a Parent or Subsidiary thereof (the “Successor Corporation”). If an Option is assumed or substituted for, the Option or equivalent option shall continue to be exercisable as provided in Section 4 hereof for so long as the Optionee serves as a Director or a director of the Successor Corporation. If the Successor Corporation does not assume an outstanding Option or substitute for it an equivalent option, the Option shall become fully vested and exercisable, including as to Shares for which it would not otherwise be exercisable. In such event the Board shall notify the Optionee that the Option shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and upon the expiration of such period the Option shall terminate.

For the purposes of this Section 10(c), an Option shall be considered assumed if, following the merger or sale of assets, the Option confers the right to purchase or receive, for each Share of Optioned Stock subject to the Option immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and

-6-

if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares). If such consideration received in the merger or sale of assets is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option, for each Share of Optioned Stock subject to the Option, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger or sale of assets.

(d) Vesting Acceleration on Change of Control. In the event of a “Change of Control,” all of the Optionee’s rights to purchase stock under all option agreements with the Company pursuant to the Plan shall be automatically vested in their entirety on an accelerated basis and be fully exercisable:

(i) as of the date immediately preceding such “Change of Control” in the event any such option agreement is or will be terminated or canceled (except by mutual consent) or any successor to the Company fails to assume and agree to perform all such option agreements; or

(ii) as of the date immediately preceding such “Change of Control” in the event the Optionee does not or will not receive upon exercise of the Optionee’s stock purchase rights under any such option agreement the same identical securities and/or other consideration as is received by all other shareholders in any merger, consolidation, sale, exchange or similar transaction occurring upon or after such “Change of Control”; or

(iii) as of the date Optionee’s status as a Director or director of the Successor Corporation, as applicable, is terminated other than upon a voluntary resignation by the Optionee occurring upon or after any such “Change of Control”; whichever shall first occur (all quoted terms as defined below).

(e) Change of Control. “Change of Control” means the occurrence of any of the following events:

(i) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), or group of “persons” acting in concert, is or becomes the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing 50% or more of the total voting power represented by the Company’s then outstanding voting securities; or

(ii) A change in the composition of the Board of Directors of the Company as a result of which fewer than a majority of the directors are “Incumbent Directors.” “Incumbent Directors” shall mean directors who either (A) are directors of the Company as of the date hereof, or (B) are elected, or nominated for election, to the Board of Directors with the affirmative votes (either by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for election as a director without objection to such nomination) of at least three-quarters of the Incumbent Directors at the time of such election or nomination (but shall not include an individual whose election or nomination is in connection with an actual or threatened proxy contest relating to the election of directors of the Company); or

-7-

(iii) The shareholders of the Company approve a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or such surviving entity’s parent) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity or such surviving entity’s parent outstanding immediately after such merger or consolidation, or the shareholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all the Company’s assets.

11. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend, or discontinue the Plan, but no amendment, alteration, suspension, or discontinuation shall be made which would impair the rights of any Optionee under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with Rule 16b-3 under the Exchange Act (or any other applicable law or regulation), the Company shall obtain shareholder approval of any Plan amendment in such a manner and to such a degree as required.

(b) Effect of Amendment or Termination. Any such amendment or termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated.

12. Time of Granting Options. The date of grant of an Option shall, for all purposes, be the date determined in accordance with Section 4(b) hereof. Notice of the determination shall be given to each Outside Director to whom an Option is so granted within a reasonable time after the date of such grant.

13. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, state securities laws, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares, if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law.

Inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

-8-

14. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

15. Option Agreement. Options shall be evidenced by written option agreements in such form as the Board shall approve.

16. Shareholder Approval. Continuance of the Plan shall be subject to approval by the shareholders of the Company at or prior to the first annual meeting of shareholders held subsequent to the granting of an Option hereunder. Such shareholder approval shall be obtained in the degree and manner required under applicable state and federal law.

(b) This Option may not be exercised for a fraction of a share.

(c) In the event of Optionee’s death, disability or other termination of service as a Director, the exercisability of the Option is governed by Section 8 of the Plan.

Such written notice, in the form attached hereto as Exhibit A, shall be signed by the Optionee and shall be delivered in person or by certified mail to the Secretary of the Company.
