All Directors' Options issued under the Plan shall have a duration of five (5) years from the date of grant, regardless of any termination of the Plan prior to the exercise of such Options. 9. NON-TRANSFERABILITY OF OPTIONS.

EXERCISE OF OPTIONS. (a) Except in the event of death, in which case they may be exercised in full immediately, and except as provided in Section 12 below, Directors' Options may be exercised only in installments as follows: (i) each annual 3,333 share grant shall vest and become fully exercisable upon the first anniversary of the date of grant and (ii) each 20,000 share grant shall vest and become fully exercisable 25% per year.

Option Agreements under the Plan may contain a provision to the effect that all Federal and state taxes required to be withheld or collected from an Optionee upon exercise of an Option may be satisfied by the withholding of a sufficient number of exercised Option shares which, valued at Fair Market Value on the date of exercise, would be equal to the total withholding obligation of Optionee. (c) The Company will, as soon as practicable after the exercise of an Option, deliver to the person entitled thereto a certificate or certificates for the Shares purchased pursuant to the exercise of the Option. 11. TERMINATION. If a holder of a Directors' Option shall resign or be removed as a director, the Option of such holder shall terminate, except that, subject to the limitation stated in the last sentence of this Section 11, (i) if his director's status with the Company is terminated for any reason other than his death, he may at any time within three months after such termination exercise his Option but only to the extent that it was exercisable by him on the date of termination and only if his status was not terminated because of a violation of his normal duties; and (ii) if he dies while serving as a director of the Company, or within three months after termination of such status, his Option may be exercised by the person or persons to whom his rights under the Option shall pass by will or by the laws of descent and distribution, without regard to the vesting provisions included in the Option. In no event may an Option be exercised to any extent by anyone after the expiration of its term. 4 5 Amended and Restated Directors' Stock Option Plan (1987) of ADAC Laboratories 12. CHANGES IN CAPITALIZATION: SPLITS, LIQUIDATIONS, MERGERS AND REORGANIZATIONS. (a) The aggregate number of shares of Common Stock for which Options may be granted to eligible persons under the Plan, the number of shares of Common Stock covered by each outstanding Option and the price per share thereof in each such Option may be proportionately adjusted by the Board of Directors or the Committee for any increase or decrease in the number of issued shares of Common Stock of the Company resulting from a stock split, a reverse stock split, a subdivision or consolidation of shares or other similar capital adjustment, the payment of a stock dividend or any other increase or decrease in such shares effected without receipt of consideration by the Company. Any such determination by the Board of Directors of the Company shall be conclusive.

A "Change in Control" of the Company shall be deemed to have occurred if (a) any "person" or "group" (as defined in or pursuant to Sections 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")), becomes the "beneficial owner" (as defined in Rule 13d-3 promulgated under the Exchange Act), directly or indirectly, of securities of the Company representing 40% or more of the voting power of the common stock outstanding which votes generally for the election of directors; (b) as a result of market or corporate transactions or shareholder action, the individuals who constitute the Board of Directors of the Company at the beginning of any period of 12 consecutive months (but commencing not earlier than July 1, 1995), plus any new directors whose election or nomination was approved by a vote of at least two-thirds of the directors still in office who were directors at the beginning of such period of 12 consecutive months, cease for any reason during such period of 12 consecutive months to constitute at least two-thirds of the members of such Board; or (c) the Company sells, through merger, assignment or otherwise, in one or more transactions other than in the ordinary course of business, assets which provided at least 2/3 of the revenues or pre-tax net income of the Company and its subsidiaries on a consolidated basis during the most recently-completed fiscal year. 5 6 Amended and Restated Directors' Stock Option Plan (1987) of ADAC Laboratories (ii) Notwithstanding paragraph (i) above, the following events shall not constitute a Change in Control: any acquisition of beneficial ownership pursuant to (a) a reclassification, however effected, of the Company's authorized common stock, or (b) a corporate reorganization involving the Company or any of its subsidiaries which does not result in a material change in the ultimate ownership by the shareholders of the Company (through their ownership of the Company or its successor resulting from the reorganization) of the assets of the Company and its subsidiaries, but only if such reclassification or reorganization has been approved by the Company's Board of Directors. 13.

Any person exercising an Option shall make such representations and furnish such information as may, in the opinion of counsel for the Company, be appropriate to permit the Company to issue the Shares in compliance with the provisions of the Securities Act of 1933, as amended. 14. AMENDMENT AND TERMINATION OF THE PLAN. (a) Except as hereinafter provided, the Board of Directors or the Committee may at any time withdraw or from time to time amend the Plan and the terms and conditions of any Options not theretofore issued, and the Board of Directors or the Committee, with the consent of the affected holder of an Option, may at any time amend the terms and conditions of such Options as have been theretofore granted. Notwithstanding the foregoing, any amendment to the Plan by the Board of Directors or Committee which would (i) increase the number of Shares issuable under Options, (ii) change the class of persons to whom Options may be granted or (iii) change in any material respect the limitations or provisions pertaining to Options, shall be subject to the approval of the holders of a majority of the shares of the Company present at any meeting of shareholders and entitled to vote thereat either prior to or within one year after such amendment. 6 7 Amended and Restated Directors' Stock Option Plan (1987) of ADAC Laboratories (b) The determination of the Board of Directors or the Committee as to any questions which may arise with respect to the interpretation of the provisions of the Plan and Options granted hereunder shall be final and conclusive.
