Purposes of the Plan. The purposes of this 1990 Director Option Plan are to attract and retain the best available personnel for service as Directors of the Company, to provide additional incentive to the Outside Directors of the Company to serve as Directors, and to encourage their continued service on the Board.

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 three hundred thousand (300,000) 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 which were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan. 4. Administration of and Grants of Options under the Plan. (a) Administrator. Except as otherwise required herein, the Plan shall be administered by the Board. No discretion con- cerning decisions regarding the Plan shall be afforded to any person who is not a "disinterested person" (as defined in Rule 16b-3 under the Exchange Act). (b) Procedure for Grants. All grants of Options hereunder 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. (ii) Each Outside Director shall be automa- tically granted an Option to purchase 10,000 Shares (the "First Option") on the date on which such person first becomes an Outside Director, whether through election by the shareholders of the Company or appointment by the Board to fill a vacancy; provided, however, that no First Option shall be granted to an Outside Director who, immediately prior to becoming an Outside Director, was a Director. After the First Option has been granted to an Outside Director, such Outside Director shall thereafter be automatically granted an Option to purchase 10,000 Shares on January 1 of each year, if on such date, he or she shall have served on the Board for at least six (6) months. (iii)The terms of each Option granted hereunder shall be as follows: (A) the term of the Option shall be ten (10) years. (B) the Option shall be exercisable only while the Outside Director remains a Director of the Company, except as set forth in Section 8 hereof. (C) the exercise price per Share shall be 100% of the Fair Market Value per Share on the date of grant of the Option. (D) the Option shall become exercisable in installments cumulatively as to twenty-five percent (25%) of the Optioned Stock one year after the date of grant and as to an addi- tional twenty-five percent (25%) of the Optioned Stock two years after the date of grant and as to an additional fifty percent (50%) of the Optioned Stock three years after the date of grant, so that 100% of the Optioned Stock granted under an individual Option shall be exercisable three years after the date of grant of the Option. (iv)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. (c) 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 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 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. (d) Effect of Board's Decision. All decisions, deter- minations 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 16 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 (x) in the case of Shares acquired upon exercise of an Option either have been owned by the Optionee for more than six (6) months on the date of surrender or were not acquired, directly or indirectly, from the Company, and (y) 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, (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 subscrip- tion 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(b) hereof; provided, however, that no Options shall be exercisable until shareholder approval of the Plan in accordance with Section 16 hereof has been obtained. 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 which 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) Rule 16b-3. Options granted to Outside Directors must comply with the applicable provisions of Rule 16b-3 promulgated under the Exchange Act or any successor thereto and shall contain such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. (c) 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 dis- ability (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 ten (10) 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. (d) 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 six (6) 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 ten (10) 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. (e) 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 six (6) 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 ten (10) 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. 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 dis- tribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. 10. Adjustments Upon Changes in Capitalization or Merger. (a) Subject to any required action by the shareholders of the Company, the number of Shares covered by each outstanding Option, and the number of Shares which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per Share covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the aggregate number of issued Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of Shares of stock of any class, or securities convertible into Shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Option. In the event of the proposed dissolution or liquidation of the Company, all outstanding Options will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Board. The Board may, in the exercise of its sole discretion in such instances, declare that any Option shall termi- nate as of a date fixed by the Board and give each Optionee the right to exercise his Option as to all or any part of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. Subject to the provisions of paragraph (b) hereof, in the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding Option shall be assumed or an equiv- alent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation. In the event that the successor corporation does not agree to assume the Option or to substitute an equivalent option, each outstanding Option shall become fully vested and exercisable, including as to Shares as to which it would not otherwise be exercisable. If an Option becomes fully vested and exercisable in the event of a merger or sale of assets, the Company 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 the Option shall terminate upon the expiration of such period. For purposes of this paragraph, an Option granted under the Plan shall be deemed to be assumed if, following the sale of assets or merger, the Option confers the right to purchase, for each Share of Optioned Stock subject to the Option immediately prior to the sale of assets or merger, the consideration (whether stock, cash or other securities or property) received in the sale of assets or merger by holders of Common Stock for each Share held on the effective date of the transaction (and if such holders were offered a choice of consideration, the type of consideration chosen by the holders if a majority of the outstanding Shares). (b) In the event of a "Change in Control" of the Company, as defined in paragraph (c) below, any Options outstanding as of the date such Change in Control is determined to have occurred that are not yet exercisable and vested on such date shall become fully exercisable and vested. (c) Definition of "Change in Control". For purposes of this Section 10, a "Change in Control" means when any "person," as such term is used in Sections 13(d) and 14(d) of the Exchange Act (other than the Company, a Subsidiary or a Company employee benefit plan, including any trustee of such plan acting as trustee) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the combined voting power of the Company's then outstanding securities. 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 amend- ment 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 afore- mentioned 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 lia- bility in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 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.
