VOTING AND SOLICITATION
 
     The required quorum for the meeting is a majority of the outstanding shares
of Common Stock eligible to be voted on the matters to be considered at the
meeting. In the election of directors, the candidates receiving the highest
number of affirmative votes cast in person or by proxy at the meeting up to the
number of directors to be elected will be elected to office. The affirmative
vote of a majority of the shares represented and voting in person or by proxy at
the meeting (which affirmative votes constitute a majority of the required
quorum) is required for approval of the amendment to the 1992 Stock Option Plan
(Proposal 2), the amendment to the Employee Stock Purchase Plan (1994) (Proposal
3), and the amendment to the Directors' Stock Option Plan (1987) (Proposal 4).
The affirmative vote of a majority of the outstanding shares of Common Stock
eligible to be voted at the meeting is required for approval of the amendment
and restatement of the Company's Articles of Incorporation (Proposal 5) and the
amendments to the Bylaws (Proposal 6).
 
     When your proxy is returned properly signed, the shares represented will be
voted in accordance with your directions. Where specific choices are not
indicated, proxies will be voted for Proposals 1 through 6. If a properly signed
proxy or ballot indicates that a stockholder, broker or other nominee abstains
from voting or that the shares are not to be voted on a particular proposal, the
shares will not be counted as having been voted on that proposal, although such
shares will be counted as being in attendance at the meeting for purposes of
 
                                        2
<PAGE>   5
 
determining the presence of a quorum. Abstentions will not be reflected in a
final tally of the votes cast for the election of directors (Proposal 1). For
purposes of determining whether the proposed amendment and restatement of the
Articles of Incorporation (Proposal 5) and the proposed amendments to the Bylaws
(Proposal 6) are approved under California law and the Bylaws of the Company,
abstentions and broker non-votes will have the effect of a negative vote because
those proposals require the approval of an absolute majority of the outstanding
shares entitled to vote at the meeting.
 
     Every shareholder voting in the election of directors may cumulate such
shareholder's votes and give one candidate a number of votes equal to the number
of directors to be elected multiplied by the number of shares of Common Stock
which such shareholder is entitled to vote, or may distribute the shareholder's
votes on the same principle among as many candidates as the shareholder chooses,
provided that votes cannot be cast for more than the number of candidates to be
elected. However, no shareholder shall be entitled to cumulate its votes unless
the candidate's name has been placed in nomination prior to the voting and the
shareholder, or any other shareholder, has given notice at the meeting prior to
the voting of such shareholder's intention to cumulate such shareholder's votes.
On all other matters, as explained above, each share of Common Stock has one
vote.
 
     The cost of soliciting proxies will be borne by the Company. The Company
may reimburse brokerage firms and other persons representing beneficial owners
of shares for their expenses in forwarding solicitation material to such
beneficial owners, estimated at $20,000. The Company has retained Skinner & Co.,
a professional proxy solicitor, to assist in the solicitation of proxies and to
arrange for dissemination of proxy materials. The agreement with Skinner & Co.
provides that the fee payable for such services will amount to $3,500; such fee
does not include expenses. Proxies may be solicited by the Company's directors,
officers or other employees, without additional compensation, personally or by
telephone, telegram or facsimile.
 
                           (1) ELECTION OF DIRECTORS
GENERAL
 
     Presently the Company's Bylaws authorize seven members to serve on the
Board of Directors. All of the seven persons presently serving as directors,
Messrs. Czerwinski, Eckert, King, Lowe, Miller, Shea and Rollo, are proposed for
election as directors. The proxy holders will be voting for all seven nominees.
 
     In the event that any nominee is unable or declines to serve as a director
at the time of the Annual Meeting, the proxies may be voted for a nominee
designated by the present Board of Directors to fill the vacancy. In the event
that additional persons are nominated for election as directors, the proxy
holders intend to vote all proxies received by them in such a manner in
accordance with cumulative voting as will assure the election of as many of the
nominees listed below as possible, and, in such event, the specific nominees to
be voted for will be determined by the proxy holders. The Company is not aware
of any nominee who will be unable or will decline to serve as a director.
Directors are elected annually by the shareholders, and the term of office of
each person elected as a director will continue until the next Annual Meeting of
Shareholders or until his successor has been elected and qualified.

                    REPORT OF THE COMPENSATION COMMITTEE ON
                   ANNUAL COMPENSATION OF EXECUTIVE OFFICERS
 
     Executive Compensation Components. The Compensation Committee of the Board
of Directors is responsible for evaluating and establishing the level of
executive compensation. It is the present philosophy of the Compensation
Committee and the Company that to achieve continual growth and financial
success, the Company must be able to attract and retain qualified executives and
must structure incentive-based compensation which is closely tied to the
Company's financial performance and operations.
 
                                        5
<PAGE>   8
 
     In fiscal 1996 and in prior years, most executive officers and other
executive-level employees participated in a management incentive program, which
makes overall executive compensation dependent upon both the accomplishment of
individual tasks and objectives, as well as Company-wide performance. Under the
management incentive program, the objectives assigned to individual executives
are intended to further the Company's financial and operating performance,
implement its strategic business plan, develop new products and maintain and
increase market share. The objectives may also include subjective criteria such
as leadership ability, innovation, insuring compliance with Company policies,
enhancing customer satisfaction and furthering the Company's strategy.
Company-wide objectives, which include the accomplishment of targeted levels of
revenues and net earnings, can also be a component of the management incentive
program. In order for an executive to achieve his or her maximum bonus under
such Program, he or she must accomplish most or all of the individual objectives
and the Company must achieve its targeted level of revenue and earnings for a
particular fiscal year.
 
     The Compensation Committee monitors the effectiveness and appropriateness
of all of the Company's executive Compensation programs, approves the base
salaries of the executive officers and, at its discretion, awards bonuses under
the Company's management incentive program and makes recommendations concerning
the grant of stock options under the Company's stock option plans.
 
     Base Salary. In determining the compensation of an executive officer, a
base salary is determined based upon the executive's level of responsibility,
the qualifications and experience required and the need to provide, together
with incentive bonuses and stock options, competitive compensation. Salary
increases are based upon periodic re-evaluations of these factors and the
performance of the executive in meeting individually-assigned objectives.
 
     Bonus Compensation. Under the management incentive program in effect in
fiscal 1996, the Compensation Committee sets objectives for each participant and
establishes the bonuses that may be earned, based upon the achievement of those
individual objectives and the Company's overall financial performance. In order
for any portion of the bonus to be earned, the executive must achieve at least
some of these objectives. Objectives may also be related to the participant's
operating unit. The Compensation Committee may grant bonuses of between 0% and
100% of base salary, based upon the performance of each participant's
individually-assigned objectives for the year, the Company's financial
performance and the executive's level of responsibility.
 
     Stock Options. Stock option grants are intended to supplement an
executive's base salary by providing long-term incentives for the achievement of
the Company's strategic business plan and financial and operational goals and to
align management's interests with those of the Company's shareholders. The size
of any stock option grant is related to the individual's level of responsibility
within the Company. Stock options are also granted to retain and attract key
employees in the very competitive job market of the Silicon Valley in which the
Company is located.
 
     CEO Compensation. Mr. David L. Lowe served as the Company's Chief Executive
Officer during all of fiscal 1996, and also served as Chairman of the Board of
the Company for the second half of fiscal 1996. Mr. Lowe's general compensation
program was established during fiscal 1993 as a result of a compensation study
of peer organizations conducted in that year by an independent compensation
consulting firm which study is updated each year. Mr. Lowe's annual base salary
for fiscal 1996 was $400,000 and he was eligible to receive a bonus of up to 50%
of his base salary based upon quarterly and annual operating results and the
accomplishment of certain goals.
 
     Of the maximum bonus for fiscal 1996 of $200,000, Mr. Lowe could be awarded
an aggregate of $120,000 on the basis of the satisfaction of certain financial
and operating goals, including revenues, earnings per share and bookings
targets, progress in clinical trials and the results of the Company's product
development and engineering efforts. On the basis of the Company's achievement
of all of these goals in fiscal 1996, Mr. Lowe was awarded a bonus of $120,000.
 
     The remaining $80,000 of the total potential bonus could be earned on the
basis of the accomplishment of certain other objective and subjective criteria.
The objective criteria related to expanding the Company's
 
                                        6
<PAGE>   9
 
addressable markets through acquisitions and internal investment. The subjective
criteria related to the development of Company systems and culture with a view
towards better integrating human resource development plans and programs
throughout the Company's operations and providing the Company with a sustainable
competitive advantage. These criteria include leadership, long-term planning,
product quality, innovation, employee satisfaction and customer satisfaction. On
the basis of the Company's achievements in these areas, Mr. Lowe was awarded a
bonus of $80,000.
 
     In addition, in light of all of the Company's outstanding achievements in
fiscal 1996, including receipt of the Malcolm Baldrige National Quality Award,
the doubling of the value of the Company's Common Stock over the year, the
improved gross margins in the Company's Medical Systems business and the results
of certain other key strategic initiatives, the Board of Directors awarded Mr.
Lowe a one-time, additional bonus of $50,000.

     Stock options generally vest and become partially exercisable one year from
the date of grant, and vest fully over three years from the date of grant. At
the time of grant, options may be designated as incentive stock options
("ISO's"), a type of option authorized under the 1981 amendments to the Internal
Revenue Code. Options not designated as an ISO are granted as "non-qualified
options." Options generally remain outstanding for five years or ten years from
the date of grant, provided the recipient remains employed throughout that
period. The post-termination exercise period is generally three months.

     Change-in-Control Agreements. In August 1995, the Company entered into
Executive Severance Agreements with Messrs. Lowe, Eckert and Lamp and, in March
1996, the Company entered into an Executive Severance Agreement with Mr. Simone
and amended Mr. Lamp's agreement. These Agreements provide for a severance
payment and acceleration of the exercisability of the executives' stock options
upon a "change in control" of the Company. A "change of control" is deemed to
occur 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.
 
     Notwithstanding the foregoing, the following events do 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.
 
     If a change in control of the Company occurs, each executive will be
entitled to a severance payment equal to 2.99 times the total cash compensation
received by each such executive, including base salary, bonuses and other
incentive compensation (excluding the value of any options), during the period
of the 12 months prior to such change in control. Such severance payment will
not be immediately paid if not later than ten days prior to the change in
control, the executive is offered employment by the Company or its successor
corporation on similar terms to those then applicable to the executive as an
officer of the Company and, in such event, the severance payment would be paid
to the executive twelve months following the change of control, but only if (i)
the executive accepts such comparable employment with the Company and (ii) the
executive is not, during such twelve-month period, terminated for cause. Such a
change in control of the Company will also cause all stock options held by the
executive to become immediately exercisable. In the event that the executive (i)
purchases the shares subject to the accelerated stock options, (ii) sells the
shares so purchased and (iii) is offered comparable employment by the Company or
its successor, the executive must deposit in escrow with the Company an amount
equal to 50% of the difference between his sales proceeds received from the sold
shares and his option exercise price. These escrowed funds will be released to
the executive from the escrow account if the executive has accepted the
comparable employment offer and is not terminated for cause for twelve months
after the change in control. If the executive does not accept such comparable
employment from the Company or its successor or is terminated for cause during
such twelve-month period, then the escrowed funds are released to the Company.
In addition, Mr. Lamp's amended Executive Severance Agreement provides that if
there is a change of control of Community Health Computing Corp. ("CHC") (as
defined in Mr. Lamp's CHC Stock Option Agreement) or if CHC is spun off by the
Company to its shareholders and, as a result, Mr. Lamp is no longer employed by
the Company or one of its subsidiaries, then, for twelve months thereafter, the
Company will retain Mr. Lamp as a part-time employee or consultant at a salary
of $1,000 per month without fringe benefits, and all of his Company stock
options will continue to vest during such period.

CERTAIN TRANSACTIONS
 
     Mr. Robert L. Miller, a director and general counsel of the Company,
received approximately $331,205 during fiscal 1996 as payment for a variety of
legal services rendered to the Company in his capacity as outside general
counsel to the Company and $21,000 for attending Board of Directors' meetings as
a director of the Company. Mr. Miller, who is not characterized as a
non-employee director, also received an option to purchase 25,000 shares of
Common Stock of the Company in part as a result of his agreement to a revised
fee arrangement with the Company for his services as outside general counsel.
 
     In November 1994, Mr. Stanley Czerwinski and the Company entered into a
10-year agreement under which he is now being paid a consulting fee of $3,000
per 8 hour day for services rendered. For the first 36 months of such agreement,
the Company has agreed to pay Mr. Czerwinski an additional $20,833 per month in
consideration of, among other things, not competing with the Company during the
term of the agreement and not selling any of his shares of common stock to the
extent that doing so would disqualify the Company from obtaining "pooling of
interests" treatment for financial reporting purposes with regard to any
acquisition transaction for which negotiations commenced on or before March 31,
1995, and which is completed on or before June 30, 1995.

              (2) APPROVAL OF AMENDMENT TO 1992 STOCK OPTION PLAN
 
GENERAL
 
     The Company currently has one stock option plan for employees and
consultants pursuant to which new options may be granted for the purchase of
Common Stock, the 1992 Stock Option Plan (the "1992 Plan"). At the 1996 Annual
Meeting of Shareholders, the shareholders approved an amendment to the 1992 Plan
increasing the number of shares authorized for issuance under the Plan to
3,801,000. During fiscal 1996, the Board of Directors granted options to
purchase an aggregate of 959,000 shares under the 1992 Plan, and as of October
31, 1996, only 628,000 shares remained available for grant. Accordingly, on
October 31, 1996, the Board of Directors approved an amendment to the 1992 Plan
to increase the number of authorized option shares by 712,000. As amended, the
1992 Plan would have a total of 4,513,000 shares of Common Stock authorized for
issuance, of which 1,340,000 shares would be available for future grant. The
Board of Directors has approved and adopted this amendment because it believes
it is very important to the long-term success of the Company for it to be able
to continue to retain and attract key management and executives and that the
continued ability to grant options is essential to retain these executives,
especially in light of the current very competitive job market in the Silicon
Valley.
 
     The following description of the 1992 Plan is necessarily brief and
general. A copy of the 1992 Plan, as amended, is available upon request from the
Company.
 
DESCRIPTION OF THE 1992 PLAN, AS AMENDED
 
     The purposes of the 1992 Plan are to attract and retain the best available
personnel for positions of substantial responsibility and to provide additional
incentives to key employees, officers, consultants or other persons whose
efforts are deemed worthy of encouragement to promote the growth and success of
the Company's business. Non-employee directors may not participate under the
1992 Plan, and instead participate under the Directors' Option Plan (1987).
 
     The 1992 Plan sets a limit of 300,000 shares which may be granted to any
one optionee during any calendar year. Options granted under the 1992 Plan may
be incentive stock options, which are intended to meet the requirements of
Section 422 of the Internal Revenue Code ("incentive options"), or nonqualified
options, which are not intended to meet such requirements ("nonqualified
options"). Incentive options must have terms of ten years or less from the date
of grant; however, the term of any such option granted to a person who owns
shares possessing more than 10% of the total combined voting power or value of
all classes of stock of the Company or any subsidiary shall not exceed five
years. The 1992 Plan also provides that nonqualified options have a term not to
exceed ten years. The Stock Option Committee has generally set terms of five
years or ten years for all options granted under the 1992 Plan. The Stock Option
Committee also determines when options granted under the 1992 Plan may be
exercisable; options granted have historically been exercisable to the extent of
25%, 25% and 50% of the number of option shares subject to an option grant 12,
24 and 36 months, respectively, after the date of grant.
 
     The option exercise prices are determined by the Board of Directors or the
Stock Option Committee and may not be less than 100% of the fair market value of
the Company's Common Stock on the date of grant, or 110% of such fair market
value if the optionee holds more than 10% of the Company's Common Stock. The
option price may be paid by cash, check, promissory note or surrender of other
shares of Common Stock of the Company that have been held for at least six
months, or a combination thereof, at the discretion of the Committee or as set
forth in the applicable stock option agreement. The 1992 Plan also provides that
whenever an optionee exercises an option by surrendering already-owned shares to
pay all or a portion of the exercise price, if the option agreement so provides
or if then approved by the Committee, the optionee may receive a new option for
the purchase of a number of shares equal to the amount tendered for payment,
with an exercise price equal to the then fair market value of a share of Common
Stock.
 
     The 1992 Plan permits an optionee, if set forth in his or her option
agreement, to have any required Federal and state withholding taxes satisfied by
either (i) delivering outstanding shares of Common Stock of the Company
previously owned for six (6) months by the Optionee or (ii) withholding of a
sufficient number
 
                                       12
<PAGE>   15
 
of exercised option shares to satisfy such withholding obligations, based upon
fair market value of such shares on the date of exercise.
 
     The 1992 Plan provides that any optionee who is terminated as an employee
or who ceases to serve as a consultant, may, within 90 days (or such other
period as may be determined by the Committee) after such termination or
cessation, exercise the option but only to the extent the optionee was entitled
to do so at the date of his or her termination or cessation of services. Special
exercise rules are applicable to optionees who become totally and permanently
disabled or who die during, or within 90 days after termination of, their period
of employment with the Company. No option may be exercised after the expiration
of its term. Options are not transferable by the optionee, other than by will,
the laws of descent and distribution or pursuant to a divorce decree.
 
     The 1992 Plan provides that in the event any change, such as a stock split,
reverse stock split or stock dividend, is made in the Company's capitalization
which results in an increase or decrease in the number of outstanding shares of
Common Stock without receipt of consideration by the Company, appropriate
adjustment shall be made in the option price and the number of shares subject to
the option. In the event of a proposed dissolution or liquidation of the
Company, or the merger of the Company with or into another corporation, each
outstanding option shall be assumed or an equivalent option shall be substituted
by the successor corporation, unless the Board of Directors determines, in its
discretion, to accelerate the exercisability of outstanding options. In
addition, upon a "change in control", except as limited by any specific
employment or severance agreement, all options will accelerate and be
immediately exercisable. The definition of "change in control" is the same as
that contained in the Executive Severance Agreements discussed earlier in this
Proxy Statement.
 
     The maximum number of shares that may be optioned and sold under the 1992
Plan may be automatically adjusted by the Board if it determines in connection
with an acquisition of another business that it is necessary to grant new or
replacement options to employees of such acquired business.
 
     The Board of Directors may amend the 1992 Plan at any time or may terminate
it without approval of the shareholders; provided, however, that shareholder
approval is required for any amendment that materially increases the number of
shares for which options may be granted under the Plan, materially increases the
benefits accruing to participants under the Plan, or materially modifies the
eligibility requirements of the Plan. However, no action by the Board of
Directors or shareholders may alter or impair any option previously granted
without the consent of the optionee.
 
ADMINISTRATION
 
     The 1992 Plan is administered by a committee of the Board consisting of not
less than two (2) persons who are "outside directors" as defined in Section
162(m) of the Internal Revenue Code.
 
OUTSTANDING OPTIONS
 
     At September 29, 1996, there were outstanding options to purchase 2,830,724
shares of Common Stock. Of these options, 148,747 were granted under the 1985
Option Plan (no further options may be granted under such Plan), 159,997 were
granted under the Directors' Stock Option Plan (1987), and 2,496,998 were
granted under the 1992 Stock Option Plan. On September 29, 1996, these
outstanding options had an aggregate exercise price of $31,284,102 or an average
of $11.05 per share, and based upon a closing price of $20.00 on September 27,
1996 (being the last trading day of the Company's 1996 fiscal year), the shares
underlying these outstanding options had an aggregate market value of
approximately $56,614,480.
 
SUMMARY OF FEDERAL TAX CONSEQUENCES
 
     Nonqualified Stock Options.  There will be no Federal income tax
consequences to an optionee at the time an option under the 1992 Plan is
granted. Upon exercise of a nonqualified option, the optionee will recognize
taxable ordinary income in an amount equal to the fair market value of the stock
on the date of exercise less the exercise price paid, and the Company will be
allowed a corresponding tax deduction for
 
                                       13
<PAGE>   16
 
compensation expense in an amount equal to the taxable income recognized by the
optionee. If the optionee is an employee of the Company, the Company is required
to withhold Federal income taxes with respect to such ordinary income amount.
Upon the subsequent sale of shares acquired upon the exercise of a nonqualified
option, the optionee generally will recognize a capital gain or loss in an
amount equal to the difference between the proceeds received upon sale and the
fair market value of such shares on the prior date of exercise.
 
     Incentive Stock Options.  There will be no Federal income tax consequences
to an optionee at the time of the initial grant of the option or at the time of
an exercise of an incentive option, although the exercise may be an item of tax
preference and may subject the optionee to the alternative minimum tax. The
Company will not be entitled to a tax deduction for compensation expense at the
time of the exercise of an incentive option. If an optionee holds stock acquired
through exercise of an incentive option for (a) more than two years from the
date on which the option is granted and (b) more than one year from the date on
which the shares are transferred to the optionee upon exercise of the option,
then income recognized at the time of the subsequent sale of the stock will be
treated as a capital gain or loss. Generally, if the optionee disposes of the
stock before the expiration of either of these holding periods (a "Disqualifying
Disposition"), at that time the optionee will realize taxable ordinary income
equal to the lesser of (i) the excess of the stock's fair market value on the
date of exercise over the exercise price or (ii) the optionee's actual gain, if
any, resulting from the purchase and sale. To the extent the optionee recognizes
income by reason of a Disqualifying Disposition, the Company will be entitled to
a corresponding tax deduction for compensation in the tax year in which the
disposition occurs.
 
     Under Section 162(m) of the Code, enacted in August 1993, the Company may
be precluded from claiming a federal income tax deduction for total remuneration
in excess of $1,000,000 paid to the CEO or the other four executive officers
named in the "Summary Compensation Table" in any one year beginning in 1995.
Total remuneration would include amounts received upon the exercise of stock
options granted after February 17, 1993. An exception does exist, however, for
"performance-based compensation," including amounts received upon the exercise
of stock options pursuant to a plan approved by shareholders that meets certain
requirements. The terms of the 1992 Plan and the shareholder approval requested
in this Proxy Statement are intended to comply with Section 162(m) of the Code
and the regulations promulgated thereunder.
 
     The foregoing discussion is merely a summary of the more significant
effects of current Federal income taxation upon optionees and the Company with
respect to shares issued under the 1992 Plan and it does not purport to be a
complete analysis of the tax laws dealing with this subject. Reference should be
made to the applicable provisions of the Internal Revenue Code and the
Regulations promulgated thereunder. In addition, this summary does not discuss
the provisions of the income tax laws of any state or foreign country in which
an employee may reside. Each employee should consult his or her own tax advisor
concerning the Federal (and state and local) income tax consequences of
participation in the 1992 Plan.
 
VOTE REQUIRED
 
     Approval of the amendment to the 1992 Plan requires the affirmative vote of
the holders of a majority of the voting shares represented and voting in person
or by proxy at the Annual Meeting (which affirmative votes also constitute at
least a majority of the required quorum). THE BOARD OF DIRECTORS RECOMMENDS A
VOTE "FOR" THIS PROPOSAL.
 
       (3)  APPROVAL OF AMENDMENT TO EMPLOYEE STOCK PURCHASE PLAN (1994)
 
BACKGROUND INFORMATION
 
     The Company has maintained an Employee Stock Purchase Plan since 1980 for
the benefit of its employees. The most recent Employee Stock Purchase Plan (the
"Purchase Plan") was approved by the shareholders during March 1994. Upon
receipt of shareholder approval at the 1996 Annual Meeting of Shareholders, the
Purchase Plan was amended to authorize the purchase of up to 185,000 shares of
Common Stock under the Plan. During fiscal 1996, the Company's employees
purchased 64,248 shares of Common Stock pursuant to the Purchase Plan, leaving
only 38,836 shares available for future purchases. To enable the
 
                                       14
<PAGE>   17
 
Company's employees to continue to benefit under the Purchase Plan, on October
31, 1996, the Board of Directors approved an amendment to the Plan to increase
the number of authorized shares by 85,000. The shareholders are being requested
to approve this increase of an additional 85,000 shares under the Purchase Plan.
None of the directors or executive officers of the Company other than Mark L.
Lamp currently participates in the Purchase Plan. Mr. Lamp purchased an
aggregate of 400 shares of Common Stock under the Purchase Plan in fiscal 1996.
 
SHARES SUBJECT TO THE PURCHASE PLAN
 
     If approved by the shareholders, an additional 85,000 shares of Common
Stock of the Company will be available for issuance under the Purchase Plan. In
the event of a stock split, stock dividend or other subdivision, combination or
classification of the Company's Common Stock, appropriate adjustments will be
made with respect to the maximum number of shares subject to, and the purchase
price of shares under, the Purchase Plan.
 
OPERATION OF THE PURCHASE PLAN
 
     The Purchase Plan provides eligible employees with the opportunity to
purchase shares of Common Stock pursuant to a payroll deduction program. The
Purchase Plan provides for offering periods of up to 27 months (the "Offering
Periods") during which contributions may be made to purchase shares of Common
Stock. Each Offering Period shall consist of interim three-month purchase
periods. At the end of each three-month interim purchase period, shares would be
purchased automatically at 85% of the market price at the beginning of the
27-month Offering Period or 85% of the market price on the last day of each
interim three-month purchase period, whichever price is lower.
 
     An employee may have up to 10% of his total compensation (including
commissions, but excluding bonuses, overtime, etc.) withheld and applied to the
purchase of shares under the Purchase Plan. However, during any one year no
employee is entitled to purchase Common Stock under the Purchase Plan having a
value of more than $25,000 or more than 100 shares of Common Stock during any
interim three-month purchase period.
 
ELIGIBILITY AND ENROLLMENT
 
     All employees of the Company may participate in the Plan. However,
employees who are customarily employed for less than 20 hours per week or for
less than 5 months in any calendar year are not eligible to participate.
Further, any employee who owns, or holds options to acquire, or who, as a result
of participation in the Purchase Plan, would own or hold options to purchase
five percent (5%) or more of the Company's securities is not eligible to
participate in the Purchase Plan.
 
     Under the Purchase Plan an employee may enroll in the Purchase Plan at the
beginning of any of the three-month interim purchase periods within an Offering
Period. An employee who joins the Purchase Plan after the beginning of the
Offering Period will have a purchase price equal to 85% of the market price on
the effective date of his joining the Purchase Plan or on the last day of each
interim three-month purchase period, whichever price is lower.
 
WITHDRAWAL; TERMINATION; RE-ENROLLMENT
 
     A participant may withdraw from the Purchase Plan at any time. Termination
of a participant's employment for any reason, including retirement or death, or
the employee's failure to remain an eligible employee, also terminates
participation in the Purchase Plan. In the event of termination, all payroll
deductions previously credited to the participant's account are returned,
without interest. The Purchase Plan allows for re-enrollment after waiting for
one complete interim three-month purchase period, except that officers and
directors would be required to wait at least six (6) months before re-enrolling.

ADMINISTRATION
 
     The Purchase Plan is administered by the Board of Directors of the Company;
the Board may also adopt and appoint a Committee thereof to administer the
Purchase Plan. The Board or any Committee so appointed has the power to make,
amend and repeal rules and regulations for the interpretation and administration
of the Purchase Plan, all of which are final and binding upon each participant
having an interest therein.
 
DURATION AND MODIFICATION
 
     The Purchase Plan will remain in full force until December 31, 2003 unless
terminated earlier by action of the Company's Board of Directors or until all of
the shares reserved for issuance thereunder have been issued. The Purchase Plan
may be terminated or amended from time to time by the Board of Directors,
provided that a participant's existing rights cannot be adversely affected
thereby, nor may any amendment be made without the approval of shareholders of
the Company if such amendment would increase the aggregate number of shares of
Common Stock to be issued under the Plan, materially modify the requirements for
eligibility to participants in the Plan, increase the maximum number of shares
which a participant may purchase during any Offering Period, extend the term of
the Plan, alter the purchase price formula so as to reduce the price per share
to be purchased under the Plan, materially increase the benefits accruing to
participants under the Plan or cause the Plan to fail to meet the requirements
of an "employee stock purchase plan" under Section 423 of the Internal Revenue
Code.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The Purchase Plan and the right of employees to make purchases thereunder
are intended to qualify under the provisions of Sections 421 and 423 of the
Internal Revenue Code. Under these provisions, no income will be taxable to an
employee at the time shares are purchased under the Purchase Plan. As summarized
below, an employee may be taxed upon disposition or sale of the shares acquired
under the Purchase Plan:
 
          1. If the shares are sold at least two years after the date of
     granting of the option and more than one year after the transfer of the
     shares to the employee: In this event, the lesser of (a) the excess of the
     fair market value of the shares at the time granted over the purchase price
     of the shares or (b) the excess of the fair market value of the shares at
     the time such shares are disposed of over the purchase price of the shares
     will be treated as ordinary income. Any further gain upon such sale will be
     treated as a capital gain. If the shares are sold and the sale price is
     less than the purchase price, there is no ordinary income and the employee
     has a capital loss equal to the difference.
 
          2. If the shares are sold prior to the expiration of two years after
     the granting of the option and less than one year after the transfer of the
     shares to the employee: In this event (a "Disqualifying Disposition"), the
     excess of the fair market value of the shares at the date the shares are
     exercised over the purchase price will be treated as ordinary income to the
     employee. This excess will constitute ordinary income in the year of sale
     or other disposition. Any further gain upon such sale will be treated as a
     capital gain. If the shares are sold for less than their fair market value
     on the date of purchase the same amount of ordinary income is attributed to
     the employee and a capital loss will be recognized equal to the difference
     between the sale price and the fair market value of the shares on such
     purchase date. To the extent the employee recognizes ordinary income by
     reason of a Disqualifying Disposition, the Company will be entitled to a
     corresponding tax deduction for compensation in the tax year in which the
     disposition occurs, provided the Company has satisfied its withholding
     obligations under the Code.
 
     In the event an employee dies while owning stock acquired under the
Purchase Plan, compensation must be reported in his/her final income return. The
amount of compensation to be reported will be the lesser of (a) the excess of
the fair market value of the shares at the time these shares were granted over
the purchase price of the shares or (b) the excess of the fair market value of
the shares at the time of the employee's death over the purchase price of the
shares.

     The foregoing discussion is merely a summary of the more significant
effects of the Federal income tax on an employee and the Company with respect to
the shares purchased under the Purchase Plan and does not purport to be a
complete analysis of the tax laws dealing with this subject. Reference should be
made to the applicable provisions of the Internal Revenue Code and the Income
Tax Regulations promulgated thereunder. In addition, this summary does not
discuss the provisions of the income tax laws of any state or foreign country in
which an employee may reside. Each employee should consult his or her own tax
advisor concerning the Federal (and any state and local) income tax consequences
of participation in the Purchase Plan.
 
VOTE REQUIRED
 
     The affirmative vote of the holders of a majority of the shares represented
and voting in person or by proxy at the meeting (which affirmative votes
constitute at least a majority of the required quorum) is required for the
approval of the amendment to the Purchase Plan. THE BOARD OF DIRECTORS
RECOMMENDS A VOTE "FOR" THIS PROPOSAL.
 
        (4) APPROVAL OF AMENDMENT TO DIRECTORS' STOCK OPTION PLAN (1987)
 
BACKGROUND INFORMATION
 
     The Company has previously determined that it is advisable and in the best
interests of the Company and its shareholders to obtain independent directors
with outstanding ability and experience and to provide incentives to such
independent directors for the encouragement of the highest level of performance
by providing such persons with a proprietary interest in the Company.
Accordingly, the Board of Directors and the shareholders previously adopted the
Directors' Stock Option Plan (1987) (the "Directors' Plan"). Under the
Directors' Plan, stock options are granted annually to each non-employee
director of the Company. An aggregate of 100,000 shares of Common Stock were
originally reserved under the Directors' Plan. Upon receipt of shareholder
approval at the 1996 Annual Meeting of Shareholders, the Directors' Plan was
amended to increase the aggregate number of shares authorized for issuance under
the Directors' Plan to 231,666. During fiscal 1996, an aggregate of 80,000
shares were optioned to non-employee directors, leaving as of October 31, 1996
only 1,668 shares available for future grants. The Board of Directors desires to
continue to be able to attract outstanding independent directors and to provide
incentives to such directors, including any additional directors that may be
recruited to the Board in the future if Proposals 5 and 6 below are approved,
and has approved an amendment to the Directors' Plan to increase the number of
available shares by 56,665.
 
DESCRIPTION OF THE DIRECTORS' PLAN
 
     The purpose of the Directors' Plan is to encourage and provide incentives
for the highest level of performance by the Company's non-employee directors.
Only directors who are not also employees of the Company or any of its
subsidiaries are eligible to participate in the Directors' Plan.
 
     As amended, an aggregate of 288,331 shares of Common Stock are authorized
under the Directors' Plan, of which 159,997 option shares have been previously
granted. The Directors' Plan provides for 20,000 option shares to be granted to
each new non-employee director upon being elected to the Board and for 3,333
option shares to be annually granted on March 15 of each year thereafter, except
that on each fifth anniversary of the year the director first commenced serving
as a director, he or she would receive on March 15 an additional grant of 20,000
shares. This schedule would repeat itself every five years (in all cases
subject, of course, to the director remaining in office). The Board of Directors
or a committee consisting of such Board members or other persons as may be
appointed by the Board administers the Directors' Plan.
 
     Each option granted has a term of five years from the date of grant. The
option exercise price must be equal to 100% of the "fair market value"
(generally, the closing price of the Company's Common Stock as traded in the
NASDAQ National Market System or other principal market) on the date of grant of
the option. The option price may be paid in cash or by surrendering to the
Company outstanding Common Stock of the Company having been owned by the
optionee for at least six (6) months, valued at fair market value. Each 20,000
share option grant would be exercisable 25% per year from the date of grant.
Each 3,333 share option grant would be fully exercisable after 12 months from
the date of grant. However, options under the
 
                                       17
<PAGE>   20
 
Directors' Plan may be exercised in full immediately in the event of the death
of the optionee. Upon a liquidation or dissolution of the Company, a
reorganization or merger pursuant to which the Company does not survive, or a
sale of substantially all of the Company's assets, each option will become
immediately exercisable without regard to the original vesting schedule. In
addition, the options would become immediately exercisable upon a "change in
control" of the Company. The definition of "change of control" is the same as
that contained in the Executive Severance Agreements and the 1992 Plan.
 
     If the holder of an option resigns or is removed as a director for reasons
other than as set forth above, he may exercise the option within three (3)
months after such resignation or removal but only to the extent it was
exercisable on such date and only if the termination did not result from a
violation of the director's normal duties. In the event of death while, or
within three (3) months after, serving as a director, the option may be
completely exercised by the person to whom the director's rights under the
option pass by will or by the laws of descent and distribution. Options are not
transferable by the optionee, other than by will or the laws of descent and
distribution or, as amended, pursuant to a qualified domestic relations order.
 
     The Directors' Plan provides that the total number of option shares covered
by such Plan, the number of shares covered by each option and the exercise price
per share shall be proportionately adjusted in the event of a stock split, stock
dividend or similar capital adjustment effected without receipt of consideration
by the Company.
 
     The Board of Directors may amend the Directors' Plan no more than once
every six (6) months. The Board may amend or terminate the Directors' Plan
without approval of the shareholders; provided, however, that shareholder
approval is required for any amendment that increases the number of shares for
which options may be granted, changes the designation of the class of persons
eligible to participate in the Directors' Plan or changes in any material
respect the limitations or provisions of the options subject to the Directors'
Plan. However, no action by the Board of Directors or shareholders may alter or
impair any option previously granted without the consent of the optionee.
 
     Options granted to directors under the Directors' Plan will be treated as
nonqualified stock options under the Internal Revenue Code. A brief description
of certain Federal income tax effects resulting from the grant and exercise of
nonqualified stock options, and the sale of the option shares, both to the
optionee and the Company, is set forth under "Approval of 1992 Stock Option
Plan -- Summary of Federal Tax Consequences" above. Such summary does not
purport to be complete, and reference is made to the applicable provisions of
the Internal Revenue Code.
 
VOTE REQUIRED
 
     Approval of the amendment to the Directors' Plan requires the affirmative
vote of the holders of a majority of the voting shares represented and voting in
person or by proxy at the Annual Meeting (which affirmative votes must
constitute at least a majority of the required quorum). THE BOARD OF DIRECTORS
RECOMMENDS A VOTE "FOR" THIS PROPOSAL.
 
                  (5) APPROVAL OF AMENDMENT AND RESTATEMENT OF
                           ARTICLES OF INCORPORATION
 
     The Board of Directors believes that it is in the best interests of both
the Company and its shareholders to amend and restate the Company's Articles of
Incorporation to delete therefrom provisions relating to the maximum and minimum
number of directors that may comprise the Board (the "Amendment to the
Articles"), in order that the Company may consolidate such provisions in the
Company's Bylaws. The text of the proposed Amended and Restated Articles of
Incorporation is set forth substantially in the form of Exhibit A to this Proxy
Statement, and has been previously adopted by the Board of Directors, subject to
approval by shareholders holding a majority of the outstanding shares of the
Company's Common Stock.
 
     At present, both the Company's Articles of Incorporation and the Company's
Bylaws contain provisions establishing a maximum and minimum number of directors
that may serve on the Company's variable Board of Directors. The Board of
Directors has determined that it is in the best interest of the shareholders and
the
 
                                       18
<PAGE>   21
 
Company to simplify the Company's Articles of Incorporation by deleting the
provisions contained therein in order that the Company may consolidate such
provisions in the Company's Bylaws, which the Company is seeking approval to
amend pursuant to Proposal 6 below. Because the shareholder approval required to
change the maximum and minimum number of directors comprising a variable board
is the same whether the maximum and minimum are set forth in the Articles or the
Bylaws, the Company believes that the deletion of this provision from the
Articles will not affect the shareholders' ability to vote on any changes in the
size of the Company's variable board and will enable the Company, upon receipt
of the appropriate shareholder approval, to make any such changes more
efficiently as only one instrument would require amendment.
 
VOTE REQUIRED
 
     Approval of the Amendment to the Articles requires the affirmative vote of
the holders of a majority of the outstanding shares of Common Stock. THE BOARD
OF DIRECTORS RECOMMENDS A VOTE "FOR" THIS PROPOSAL. If the Amendment to the
Articles is not approved but the amendments to the Bylaws described below in
Proposal 6 are approved by the shareholders, the shareholders' approval of the
Bylaw amendments will be deemed to constitute approval by the shareholders to
amend the Articles of Incorporation to the extent necessary to conform the
provisions of the Articles regarding the size of the Company's variable board to
the corresponding amended Bylaw provision set forth in Exhibit B to this Proxy
Statement.
 
                      (6) APPROVAL OF AMENDMENTS TO BYLAWS
 
     The Board of Directors believes it is in the best interests of the Company
and the shareholders to adopt amendments to the Bylaws of the Company to
increase the number of directors that may serve on the Company's variable board.
The Board of Directors believes it is advisable to increase the number of
directors that may serve on the Company's variable board in order to give the
Company the flexibility in the future to add directors with experience that may
be critical to the Company's ability to achieve its long-term strategic goals.
Accordingly, the Board of Directors has approved amendments to the Bylaws,
subject to approval by shareholders holding a majority of the outstanding shares
of Common Stock of the Company, that (i) provide that the Board of Directors
will consist of not less than six nor more than eleven directors, with the exact
number to be fixed by approval of the Board of Directors or the shareholders,
and with the number initially fixed in the Bylaws at seven, and (ii) define the
authority of the Board of Directors to fix the exact number of the directors
within the foregoing range in accordance with California law. The proposed text
of the amendments to the Bylaws is set forth substantially in the form of
Exhibit B to this Proxy Statement.
 
VOTE REQUIRED
 
     Approval of the amendments to the Bylaws requires the affirmative vote of
the holders of a majority of the outstanding shares of Common Stock. THE BOARD
OF DIRECTORS RECOMMENDS A VOTE "FOR" THIS PROPOSAL.
 
                RELATIONSHIP WITH INDEPENDENT PUBLIC ACCOUNTANTS
 
     The firm of Coopers & Lybrand, L.L.P. has examined the financial statements
of the Company for the fiscal year ended September 29, 1996, and has been
selected to perform such service for the current fiscal year. A representative
of Coopers & Lybrand, L.L.P. is expected to be present at the Annual Meeting
with the opportunity to make a statement if he or she desires to do so and is
expected to be available to respond to appropriate questions. The Company has
been advised that neither that firm, nor any of its partners or associates, has
any direct or indirect financial interest in or any connection with the Company
other than as accountants and auditors.

                                 OTHER MATTERS
 
SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     The Securities and Exchange Commission's rules under Section 16 of the
Securities Exchange Act of 1934 require the Company's officers and directors,
and persons who own more than ten percent (10%) of a registered class of the
Company's equity securities, to file reports showing their initial stock
ownership and subsequent changes in such ownership with the SEC by specific
dates.
 
     Based solely on its review of the copies of such forms received by it or
written representations from the Company's appropriate officers and directors,
the Company believes that, during the 1996 fiscal year, all filing requirements
applicable to its officers and directors were complied with, except for the
following: One report on Form 4 concerning the exercise of options to purchase
8,750 shares of Common Stock and the sale of such shares by Mr. Simone on
September 4, 1996 was not filed but such transactions were reported in a Form 5
filed for the fiscal year ended September 29, 1996. Two Form 5s concerning Mr.
Lamp's purchase of 100 shares of Common Stock under the Purchase Plan on each of
the four quarterly purchase dates in fiscal 1995 and 1996 were not filed but
were subsequently disclosed in an amended Form 4.
 
SHAREHOLDER PROPOSALS
 
     Individual shareholders of the Company may be entitled to submit proposals
which they believe should be voted upon by the shareholders. The Securities and
Exchange Commission has adopted regulations which govern the inclusion of such
proposals in annual proxy materials. All such proposals must be submitted to the
Secretary of the Company no later than October 10, 1997 in order to be
considered for inclusion in the Company's 1998 proxy materials related to the
1998 Annual Meeting of Shareholders.
 
OTHER BUSINESS
 
     Management does not know of any business to be presented other than the
matters set forth above, but if other matters properly come before the meeting,
it is the intention of the persons named in the Proxy to vote in accordance with
their best judgment on such matters.
 
AVAILABILITY OF FORM 10-K
 
     THE COMPANY WILL FURNISH WITHOUT CHARGE A COPY OF ITS ANNUAL REPORT ON FORM
10-K FOR THE FISCAL YEAR ENDED SEPTEMBER 29, 1996, AS FILED WITH THE SECURITIES
AND EXCHANGE COMMISSION, TO ANY SHAREHOLDER DESIRING A COPY. Shareholders may

                              AMENDED AND RESTATED
                      DIRECTORS' STOCK OPTION PLAN (1987)
                                       OF
                               ADAC LABORATORIES



                 1.       PURPOSE.

                 The purpose of this Directors' Stock Option Plan (1987) (the
"Plan") is to assist the Company in attracting, motivating and retaining
qualified non-employee directors by providing a means whereby such persons will
be given an opportunity to acquire a proprietary interest in the Company's
future growth by purchasing shares of Company Common Stock.

                 2.       DEFINITIONS.

                 When used in this Plan, unless the context otherwise requires:

                          (a)     "Board of Directors" shall mean the Board of
Directors of the Company as constituted at any time.

                          (b)     "Committee" shall mean the Committee as
hereinafter described in Section 3 hereof.

                          (c)     "Company" shall mean ADAC Laboratories, a
California corporation.

                          (d)     "Directors' Options" shall mean options to
purchase shares of Company Common Stock which may be granted each fiscal year
by the Company to each person serving as a director of the Company who is not
also an employee of the Company or any of its Subsidiary corporations.

                          (e)     "Fair Market Value" shall mean the closing
price of the Company's Common Stock, as traded on the NASDAQ National Market
System (or, if such shares are then listed on any national securities exchange,
the closing price on such exchange) on the date as of which such value is being
determined.  If the Common Stock is not traded on the NASDAQ National Market
System or any national securities exchange, Fair Market Value shall be
determined by the Board on the basis of the best available market value
information.

                          (f)     "Options" shall mean the Directors' Options
issued pursuant to the Plan.

                          (g)     "Plan" shall mean the Directors' Stock Option
Plan (1987) of the Company authorized and adopted by the Board of Directors at
its meeting held on July 28, 1987 and as amended from time to time.

of ADAC Laboratories



                          (h)     "Share" shall mean a share of Common Stock of
the Company.

                          (i)     "Subsidiary" shall mean any corporation in
which the Company owns, directly or indirectly, stock possessing fifty percent
(50%) or more of the total combined voting power of all classes of stock.

                 3.       ADMINISTRATION.

                 The Plan shall be administered by the Board of Directors or by
a Committee which shall consist of such members of the Board of Directors of
the Company or such other persons as may be appointed by the Board of
Directors.  The Board and, if any, the Committee, shall have full power and
authority to construe, interpret and administer the Plan and to make
determinations which shall be final, conclusive and binding upon all persons,
including but not limited to the Company, the shareholders and any person
having an interest in any Options.  If a member of the Committee, for any
reason, shall cease to serve, the vacancy may be filled by the Board of
Directors.  Any member of the Committee may be removed at any time, with or
without cause, by the Board of Directors.

                 4.       ELIGIBILITY.

                 Options may be granted only to non-employee directors of the
Company; employees of the Company or any of its Subsidiary corporations are not
eligible to receive Options under the Plan.

                 5.       SHARES SUBJECT TO THE PLAN.

                 Subject to the provisions of Section 12 (relating to
adjustments upon changes in shares), the Shares which may be sold pursuant to
Directors' Options granted under the Plan shall not exceed in the aggregate
231,666 shares of the Company's authorized Common Stock, without par value.  If
any Option under the Plan shall for any reason terminate or expire without
having been exercised in full, the Shares not purchased under such Option shall
again be available under the Plan.

                 6.       ANNUAL OPTION GRANTS.

                          The number of shares to be optioned to each
non-employee director shall be fixed at 3,333 Option Shares during each fiscal
year of the Company and such grant shall automatically occur on March 15th of
each year  except during each fifth year the

director shall receive a grant of 20,000 shares (in lieu of the 3,333 share
annual grant), provided, however, that on the date a person first becomes a
director such person shall receive an option grant of 20,000 shares.  Each
option shall be for a term of five (5) years from the date of grant and each
annual 3,333 share grant shall vest and become fully exercisable upon the first
anniversary of the date of grant and each 20,000 share grant shall vest and
become exercisable 25% per year.  An option agreement, signed by an officer of
the Company, shall be issued to each person to whom an option is granted.

                 7.       PRICE.

                 The purchase price per Share for the Shares to be purchased
pursuant to the exercise of any Option shall be fixed by the Board of Directors
or the Committee at the time of grant of the Option, but shall always equal
100% of the Fair Market Value of the Shares on the date such Option is granted.

                 8.       DURATION OF OPTIONS.

                 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.

                          (a)     Options shall not be transferrable by the
holder thereof otherwise than (i) by will, (ii) pursuant to the laws of descent
and distribution or (iii) if then permitted by Rule 16b-3, promulgated under
the Securities Exchange Act of 1934, as amended, pursuant to a qualified
domestic relations order as defined by the Internal Revenue Code of 1986, as
amended, or by Title I of the Employee Retirement Income Security Act (ERISA),
or the rules thereunder; provided, however, that an Option holder may designate
a beneficiary who, upon Option holder's death, may exercise the Option to the
extent permitted in Section 10 of the Plan.

                          (b)     Subject to early acceleration as provided
herein, at least six months must elapse from the date of the grant of the
Directors' Options to the date of disposition of the Directors' Option (other
than upon exercise or conversion) or the shares subject to such Directors'
Option.

                 10.      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.

                          (b)     An Option shall be exercised by the delivery
of a duly signed notice in writing to such effect, together with the full
purchase price.  Payment of the purchase price shall be made in cash or
outstanding Common Stock of the Company already owned by the optionee (valued
at Fair Market Value).  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.

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.

                          (b)(i)  Except and to the extent provided otherwise
in, or limited by, employment, severance or similar written agreements between
the Company and an Optionee, ten (10) days prior to a "Change in Control" (as
defined below), all stock options which are then not exercisable shall
immediately vest and become exercisable, regardless of the original vesting
schedule.  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.

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.      ISSUANCE OF SHARES AND COMPLIANCE WITH SECURITIES
ACT.

                 The Company may postpone the issuance and delivery of Shares
upon any exercise of an Option until (a) the admission of such Shares to
listing on any stock exchange on which Shares of the Company of the same class
are then listed and (b) the completion of such registration or other
qualification of such Shares under any state or Federal law, rule or regulation
as the Company shall determine to be necessary or advisable.  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.

                          (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.

                          (c)     The Board of Directors or the Committee may
authorize and establish such rules, regulations and revisions thereof, not
inconsistent with the provisions of the Plan, as it may deem advisable to make
the Plan and Options effective or provide for their administration, and may
take such other action with regard to the Plan and Options as it shall deem
desirable to effectuate their purpose.

                          (d)     The Plan shall remain in effect until such
time as it is terminated by the Board of Directors of the Company.  No such
termination shall affect Options granted prior thereto.

                          (e)     Notwithstanding anything in the Plan to the
contrary, the terms and conditions of this Plan shall not be amended more than
once every six months other than to comport with changes in the Internal
Revenue Code, the Employee Retirement Income Securities Act, or the rules
thereunder.

                 15.      EFFECTIVE DATE OF THE PLAN.

                 The Plan was adopted on July 28, 1987, and is subject to
approval of the holders of a majority of the shares of the Company present at
any meeting of shareholders and entitled to vote thereat.  Options may not be
granted under the Plan prior to such shareholder approval.

                                        Adopted by the Board of
                                        Directors on July 28, 1987

                 in Rule 16b-3 promulgated under the Securities Exchange Act of
                 1934, as amended, and, in addition, as may be further defined
                 under Section 162(m) of the Internal Revenue Code of 1986.
                 The Committee may be an existing committee of the Board or a
                 new committee organized for the purpose of administering the
                 Plan.  Options granted to any person who is both an employee
                 and a Director may be granted only by the Committee.

                          (ii)    An Option to an Officer may be granted by the
                 Board if each member thereof is then a "disinterested person"
                 (as hereinabove defined).  Otherwise, an Option to an Officer
                 may be granted only by the Committee.

                          (iii) A Option to a person who is neither an Officer
                 nor a Director may be granted by either the Board or the
                 Committee.

                          (iv)    Subject to the foregoing, the Board may, from
                 time to time, increase the size of the Committee and appoint
                 additional members thereof, remove members (with or without
                 cause) and appoint new members in substitution therefor, fill
                 vacancies however caused or remove all members of the
                 Committee.  All actions of the Board or the Committee, if
                 taken in accordance with the Company's Bylaws, shall be valid
                 notwithstanding the fact that one or more of the members
                 thereof do not constitute "disinterested persons", as
                 hereinabove defined.

                 (b)      POWERS OF THE BOARD.  Subject to the provisions of
the Plan, the Board and the Committee shall have the authority, in its
discretion:

                          (i)     to determine, upon review of relevant
                 information, the fair market value of the Common Stock;

                          (ii)    to determine the persons to whom Options
                 shall be granted, the time or times at which Options shall be
                 granted, the number of Shares to be represented by each Option
                 and the exercise price per Share;

                          (iii) to interpret the Plan;

                          (iv)    to prescribe, adopt, amend, and rescind rules
                 and regulations relating to the Plan;

                          (v)     to determine whether an Option granted shall
                 be an Incentive Option or a Nonqualified Option and to
                 determine the terms and provisions of each Option granted
                 (which need not be identical) and, with the consent of the
                 holder thereof, to modify or amend each Option;

                          (vi)    to determine the exercise date(s) and the
                 number of shares exercisable at each such date, and to
                 accelerate or defer (with the consent of the Optionee) the
                 exercise date of any Option;

                          (vii) to authorize any person to execute on behalf of
                 the Company any instrument required to effectuate the grant of
                 an Option previously approved by the Board or the Committee;

                          (viii)  to make such adjustments to Options granted
                 under the Plan to enable them to comply with the laws of
                 foreign jurisdictions and/or to make them consistent with
                 options customarily utilized by companies in foreign
                 jurisdictions;

                          (ix)    to make all other determinations deemed
                 necessary or advisable for the administration of the Plan.

                          (x)     Notwithstanding the number of shares set
                 forth in Section 3, the maximum aggregate number of shares
                 subject to the Plan may be automatically increased by the
                 Board, at its discretion and without shareholder approval, if
                 the Board determines in connection with an acquisition of
                 another business (whether by merger, consolidation or purchase
                 of assets or otherwise) that it is necessary to grant a
                 substantial number of new options to employees of, or persons
                 holding options in, such acquired business to replace existing
                 options, to grant new options to incentivize the employees or
                 replace other equity rights previously granted to such persons
                 by the acquired business.  The amount of the additional number
                 of shares to become subject to the Plan shall not exceed the
                 number of new options granted in connection with such
                 acquisition.

                 (c)      EFFECT OF DECISIONS.  All decisions, determinations,
and interpretations of the Board or the Committee shall be final and binding on
all Optionees and any other holders of any Options granted under the Plan.

         5.      ELIGIBILITY; MAXIMUM ANNUAL LIMITATION.  Options may be
granted only to Employees, Officers, Consultants or other persons whose efforts
are deemed by the Board or the Committee to be  worthy of encouragement in
order to promote the growth and success of the Company.  A person who has been
granted an Option may, if he/she is otherwise eligible, be granted an
additional Option or Options.  Options under the Plan may not be granted to any
non-employee director.  The aggregate number of shares of Common Stock with
respect to which Options may be granted to any one Optionee shall not exceed
300,000 shares in any calendar year, subject to adjustment in accordance with
Section 11.

                 Neither the Plan nor any Option granted hereunder shall confer
upon any Optionee any right with respect to continuation of employment with the
Company, nor shall it interfere in any way with his/her right or the Company's
right to terminate his/her employment at any time, with or without cause.

         6.      TERM OF PLAN.  The Plan shall continue in effect for a term of
ten (10) years unless sooner terminated under Section 13 below.  Options may be
granted hereunder immediately.

         7.      TERM OF OPTION.  The term of any Incentive Option granted
under the Plan shall be for a period of not to exceed ten (10) years from the
date on which it is granted, as determined by the Board of Directors or the
Committee; provided, however, that any Incentive Option granted to any person
who owns shares possessing more than ten percent (10%) of the total combined
voting power or value of all classes of stock of the Company or of a Subsidiary
of the Company shall have a term of not to exceed five (5) years.  The term of
a Nonqualified Option shall be for a period of not to exceed ten (10) years
from the date on which it is granted, as determined by the Board of Directors
or the Committee.

         8.      EXERCISE PRICE AND CONSIDERATION.

                 (a)      EXERCISE PRICE.  The per share exercise price for the
Shares to be issued pursuant to the exercise of an Incentive Option shall not
be less than one hundred percent (100%) of the fair market value of the
Company's Common Stock on the date of grant as determined by the Board or the
Committee; provided, however, that any Incentive Option granted to any person
who owns shares possessing more than ten percent (10%) of the total combined
voting power or value of all classes of stock of the Company or of a Subsidiary
thereof shall have a per share exercise price of one hundred ten percent (110%)
of the fair market value of the Company's Common Stock on the date of grant as
determined by the

Board or the Committee.  The per share exercise price for Shares to be issued
pursuant to the exercise of a Nonqualified Option shall not be less than one
hundred percent (100%) of the fair market value of the Company's Common Stock
on the date of grant as determined by the Board or the Committee.

                 (b)      FAIR MARKET VALUE.  The fair market value shall be
determined by the Board or the Committee in its discretion; provided, however,
that if there is a public market for the Common Stock, the fair market value
per Share shall be, in the event the Common Stock is listed on the NASDAQ
National Market System or on a stock exchange, the closing price on such
National Market System or exchange on the date of grant of the Option, as
reported in the "Wall Street Journal", and, if not so listed, fair market value
shall be the mean of the bid and asked prices of the Common Stock on the date
of the grant, as reported in the "Wall Street Journal" (or, if not so reported,
as otherwise reported by the National Association of Securities Dealers
Automated Quotation (NASDAQ) System).

                 (c)      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 or the Committee and may consist
entirely of cash, check, promissory note or shares of Company Common Stock
(which must have been held for at least six (6) months) having a fair market
value on the date of surrender equal to the aggregate exercise price of the
Shares as to which the Option shall be exercised, or any combination of such
methods of payment, or other consideration and method of payment for the
issuance of Shares to the extent permitted under Section 408 and 409 of the
California General Corporation Law.  In making its determination as to the type
of consideration to accept, the Board or the Committee shall consider whether
such consideration may be reasonably expected to benefit the Company.

                 (d)      RE-LOAD OPTION.  Whenever an Optionee exercises an
Option by surrendering already-owned shares to pay all or a portion of the
exercise price, if the Option Agreement so provides or if permitted by the
Board or the Committee, at its discretion, at the time of such exercise, the
Optionee shall receive a new Option for the purchase of a number of Shares
equal to the number of Shares so surrendered, and such new Option shall have an
exercise price of not less than the fair market value of a Share of Common
Stock on the date of such surrender and shall vest and become exercisable as
may be determined by the Board or the Committee.

                 (e)      WITHHOLDING TO PAY TAXES.  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 either (i) delivering outstanding shares of Common
Stock of the Company previously owned for six (6) months by the Optionee or
(ii) 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 the Optionee; provided, however, that no person
who is an "officer" of the Company, as such term is defined in Rule 3b-2 under
the Securities Exchange Act of 1934, may elect to satisfy the withholding of
Federal and state taxes upon the exercise of an Option by the withholding of
Optioned Stock unless such election is made either (i) at least six months
prior to the date that the exercise of the Option becomes a taxable event or
(ii) during any of the periods beginning on the third business day following
the date on which the Company releases publicly the operating results of a
fiscal quarter or fiscal year and ending on the twelfth (12th) business day
following such date.  Such election shall be deemed made upon receipt of notice
thereof by an officer of the Company, by mail, personal delivery or by
facsimile message, and shall be operative for all Option exercises which occur
following the election, until terminated by a notice revoking such withholding
election (such termination shall become effective six (6) months after the date
of such new notice).

         9.      EXERCISE OF OPTION.

                 (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER.

                          (i)     Any Option granted hereunder shall be
exercisable at such times and under such conditions as determined by the Board
or the Committee, including performance criteria with respect to the Company
and/or the Optionee, and as otherwise permissible  under the terms of the Plan.

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

                          (iii) 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; provided, however, that the Board or the
Committee may prescribe and adopt rules and procedures allowing an Optionee to
exercise an Option and sell the Optioned Stock simultaneously (or on the same





                                       7

Amended and Restated




business day) under circumstances which provide reasonable certainty that the
Company will receive the Option exercise price by the settlement date of the
sale of the Optioned Stock.  Until the issuance (as evidenced by an 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.  No
adjustment shall 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 11 below.

                          (iv)    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 exercise under the Option, by the number
of Shares as to which the Option is exercised.

                 (b)      TERMINATION OF CONTINUOUS STATUS AS AN EMPLOYEE OR
CONSULTANT.

                          (i)     Except as set forth in Section 9(b)(ii)
below, if an Employee or Consultant ceases his/her Continuous Status as an
Employee or Consultant (as the case may be), he/she may, but only within ninety
(90) days (or, with respect to Nonqualified Options, such longer period of time
as may be determined by the Board or the Committee), after the date he/she
ceases to have such Continuous Status, exercise his/her Option to the extent
that he/she was entitled to exercise it at the date of such termination.

                          (ii)    Notwithstanding the provisions of Section
9(b)(i) above, if the holder of an Option (A) is terminated due to Optionee's
willful refusal to perform the normal and/or reasonable duties and
responsibilities delegated to Optionee as an Employee of the Company, (B) is
terminated due to Optionee's expropriation of Company property (including trade
secrets or other proprietary rights), or (C) leaves the employment of the
Company in order to directly (or indirectly, as an employee or agent of another
business or business entity) compete with the Company, the Board or the
Committee shall have the authority, by notice to the holder of an Option, to
immediately terminate such Option, effective on the date of termination, and
such Option shall no longer be exercisable to any extent whatsoever.

                 (c)      RETIREMENT.  Notwithstanding the provisions of
Section 9(a) above, if an Optionee ceases Continuous Status as an





                                       8
<PAGE>   9

1992 Stock Option Plan,
Amended and Restated




Employee or Consultant as a result of retiring as an active Employee or
Consultant of the Company at age 62 or older, such ninety-day period shall be
extended to one (1) year.  To the extent that Optionee was not entitled to
exercise the Option at the date of such termination, or if Optionee does not
exercise such Option within the time specified herein, the Option shall
terminate.


                 (d)      DISABILITY.  Notwithstanding the provisions of
Section 9(a) above, in the event an Employee or Consultant is unable to
continue his/her employment or consulting relationship (as the case may be)
with the Company as a result of his/her total and permanent disability (as
defined in Section 105(d)(4) of the Code), he/she may, but only within a period
of up to twenty-four (24) months (or such shorter or longer period of time as
is determined by the Board or the Committee or as set forth in the Option
Agreement) from the date of termination, exercise the Option to the extent
Optionee was entitled to exercise it at the date of such termination.  To the
extent that Optionee was not entitled to exercise the Option at the date of
termination, or if Optionee does not exercise such Option within the time
specified herein, the Option shall terminate.

                 (e)      DEATH OF OPTIONEE.  In the event of the death of an
Optionee which occurs during the time in which an Option may be exercised, such
Option may be exercised at any time within two (2) years following the date of
death or such shorter period as may be set forth in the Option Agreement, by
the Optionee's estate or by a person who acquired the right to exercise the
Option by bequest or inheritance, but only to the extent of the right to
exercise that would have accrued had the Optionee continued living and remained
in Continuous Status as an Employee or Consultant for two (2) years after the
date of death.

                 (f)      DESIGNATION OF BENEFICIARY.  Notwithstanding anything
in the Plan to the contrary, any Option Agreement issued under the Plan may
provide for the designation of a beneficiary of the Optionee (which may be an
individual or a trust) who may exercise the Option after the Optionee's death
and enjoy the economic benefits thereof, subject to the consent of Optionee's
spouse if required by law.

         10.     NON-TRANSFERABILITY OF OPTIONS.

                 Options shall not be transferable by the holder thereof
otherwise than (i) by will, (ii) pursuant to the laws of descent and
distribution or (iii) pursuant to a dissolution of marriage, whether pursuant
to a qualified domestic relationship order,





                                       9

stipulation between the optionholder and spouse or otherwise; provided,
however, that an Optionee may designate a beneficiary who, upon Optionee's
death, may exercise the Option to the extent permitted in Section 9 of the
Plan.

         11.     ADJUSTMENTS.

                 (a)      STOCK SPLITS, DIVIDENDS AND OTHER COMBINATIONS.
Subject to any required action by the shareholders of the Company, the number
of shares of Common Stock covered by each outstanding Option, and the number of
shares of Common Stock 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 of Common Stock covered by each such outstanding Option, shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock 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 number of issued shares of Common Stock 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 or the Committee, 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
of Common Stock subject to an Option.

                 (b)      DISSOLUTION OR LIQUIDATION.  In the event of the
proposed dissolution or liquidation of the Company, each Option shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board or the Committee.  The Board or the Committee may, in the
exercise of its sole discretion in such instances, declare that any Option
shall terminate as of a date fixed by the Board or the Committee and give each
Optionee the right to exercise his/her Option as to all or any part of the
Optioned Stock, including Shares as to which the Option would not otherwise be
exercisable.

                 (c)      SALE OF ASSETS OR MERGER.  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, the Option shall be assumed or an
equivalent option

(containing the same vesting schedule and equivalent exercise price) shall be
substituted by such successor corporation or a parent or subsidiary of such
successor corporation, unless the Board or the Committee determines, in the
exercise of its sole discretion and in lieu of such assumption or substitution,
that the Optionee shall have the right to exercise the Option as to all of the
Optioned Stock, including Shares as to which the Option would not otherwise be
exercisable.  If the Board or the Committee makes an Option fully exercisable
in lieu of assumption or substitution in the event of a merger or sale of
assets, then the Board shall notify the Optionee that the Option shall be fully
exercisable for a period of thirty (30) days from the date of such notice, and
the Option shall terminate upon the expiration of such period.

                 (d)      CHANGE IN CONTROL.

                          (i)     Except and to the extent provided otherwise
in, or limited by, employment, severance or similar written agreements between
the Company and an Optionee, ten (10) days prior to a "Change in Control" (as
defined below), all stock options which are then not exercisable shall
immediately vest and become exercisable, regardless of the original vesting
schedule.  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.

                          (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.

         12.     SPECIAL PROVISIONS RELATING TO INCENTIVE OPTIONS.  The Company
shall not grant Incentive Options under the Plan to any Optionee to the extent
that the aggregate fair market value of the Common Stock covered by such
Incentive Options which are exercisable for the first time during any calendar
year, when combined with the aggregate fair market value of all stock covered
by incentive stock options granted to such Optionee after December 31, 1986 by
the Company, its Parent or a Subsidiary thereof which are exercisable for the
first time during the same calendar year, exceeds $100,000.  Incentive Options
shall be granted only to persons who, on the date of grant, are Employees of
the Company or a Parent or a Subsidiary of the Company.  Notwithstanding the
above, to the extent the fair market value of Shares subject to Incentive Stock
Options first exercisable in a calendar year is greater than $100,000, the
excess Options shall be treated as Non-qualified Options.

         13.     AMENDMENT AND TERMINATION OF THE PLAN.

                 (a)      AMENDMENT AND TERMINATION.  The Board or the
Committee may at any time suspend, amend or terminate the Plan with or without
shareholder approval; provided, however, that if the Plan has been previously
approved by the shareholders, no amendment or modification may be adopted
without shareholder approval if the amendment would (i) materially increase the
benefits accruing to participants under the Plan; (ii) materially increase the
number of Shares which may be issued under the Plan or (iii) materially modify
the requirements as to the eligibility for participation in the Plan.

                 (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 the Plan had not
been amended or terminated, unless mutually agreed otherwise between the
Optionee and the Board or the Committee, which agreement must be in writing and
signed by the Optionee and the Company.

         14.     CONDITIONS UPON ISSUANCE OF SHARES.

                 (a)      COMPLIANCE WITH SECURITIES LAWS.  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 complies with all
relevant provisions of law, including, without limitation, the Securities Act
of 1933, the Securities Exchange Act of 1934, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which
the Shares may then be listed.  The exercise of such Option and the issuance
and delivery of such Shares pursuant thereto shall be further subject to the
approval of counsel for the Company with respect to such compliance.

                 (b)      INVESTMENT REPRESENTATION.  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.

         15.     RESERVATION OF SHARES.  The Company, during the term of the
Plan, will at all times reserve and keep available such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.  The 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.

         16.     OPTION AGREEMENTS.  Options shall be evidenced by written
Option Agreements in such form as the Board or the Committee shall approve.

         17.     SHAREHOLDER APPROVAL.  The Plan shall become effective when
approved by the Board or any committee thereof having authority to do so and
the shareholders of the Company.

         5.      ELIGIBILITY AND PARTICIPATION.

                 (a)      INITIAL PARTICIPATION.  An Eligible Employee shall
become a Participant on the Offering Date after satisfying the eligibility
requirements by delivering to the Company's payroll office an enrollment form
authorizing payroll deductions not less than ten (10) business days prior to
such Offering Date.  An Eligible Employee who did not enroll in the Plan prior
to the Offering Date, or a person who becomes an Eligible Employee after an
Offering Date, may enroll in the Plan for the remainder of the Offering Period
as of the beginning of the next Interim Offering Period by completing and
filing an enrollment form prior to the commencement date of such Interim
Offering Period.

                 (b)      CONTINUED PARTICIPATION.  A Participant shall
automatically participate in each successive Offering Period (including Interim
Offering Periods) until such time as such Participant withdraws from the Plan
as set forth below.  A Participant is not required to file any additional
enrollment forms for subsequent Offering Periods in order to continue
participation in the Plan.

                 (c)      PAYROLL DEDUCTION RATE.  The Participant shall
designate on the enrollment form the percentage of Compensation which he or she
elects to have withheld for the purchase of Stock, which may be any whole
percentage from 1% to 10% of the Participant's Compensation.  A Participant may
reduce (but not increase) the rate of payroll withholding during an Offering
Period by filing an amended enrollment form with the Committee at any time
prior to the last day of any Interim Offering Period (for which such change is
to be effective), but not more than three (3) changes may be made in any
Offering Period (or such other number of changes as may be approved by the
Board or the Committee).  A Participant may increase or decrease the rate of
payroll deduction for any subsequent Offering Period by filing with the Company
a new authorization for payroll deductions not less than ten (10) days prior to
the Offering Date for such subsequent Offering Period.

                 By enrolling in the Plan, a Participant shall be deemed to
have elected to purchase the maximum number of whole shares of Stock which can
be purchased with the amount of the Participant's Compensation which is
withheld during the Offering Period; provided, however, that with respect to
any Interim Offering Period no Participant may purchase more than 100 shares of
Stock or shares of Stock in excess of the amount permitted under Section 9.

                 (d)      OFFERING PERIOD.  Any Options granted pursuant to the
Plan shall be subject to the Company obtaining all necessary governmental
approvals and/or qualifications of the sale and/or issuance of Options and/or
Stock.

Amended and Restated
Employee Stock Purchase Plan (1994)



                 (e)      PURCHASE PRICE.  The Purchase Price for each share of
Stock to be purchased under the Plan shall be eighty-five percent (85%) of the
Fair Market Value of such share on either (i) the Offering Date (or the date of
entry for new or re-enrolling employees) or (ii) the last day of each Interim
Offering Period, whichever is less.

                 (f)      CONTRIBUTIONS.  The Purchase Price of the Stock shall
be accumulated by payroll deductions throughout the Offering Period, which
shall be applied automatically to purchase Stock at the end of each Interim
Offering Period. In the absence of a contrary determination prior to the
commencement of an Offering Period, each Interim Offering Period shall have the
durations described in Section 2(h) of the Plan.  At the end of each Interim
Offering Period, accrued payroll deductions will be automatically applied to
the purchase of Stock at the Purchase Price as hereinabove defined.  Payroll
deductions shall commence on the first payday following the Offering Date (or,
in the case of a new or re-enrolling employee, on the first payday following
the commencement of the applicable Interim Offering Period) and shall continue
to the end of the Offering Period unless sooner altered or terminated as
provided in the Plan.

                 (g)      EFFECT OF LEAVE OF ABSENCE.  During a leave of
absence approved by the Company, a Participant may, for such period as the
Committee shall deem reasonable, continue contributions to the Plan by making
cash payments to the Company on his normal paydays in an amount equal to the
difference between the amount of his regular payroll deductions taken while
such employee was participating under the Plan and the amount of his payroll
deductions taken while on such leave of absence.  Failure to pay any
installment within ten (10) days after the payday on which it is due shall be
treated as a withdrawal from the Plan.

                 (h)      PURCHASE OF STOCK.  The Company will maintain a Plan
Account on its books in the name of each Participant.  On each payday the
amount deducted from the Participant's Compensation will be credited to the
Participant's Plan Account.  No interest shall accrue on any such payroll
deductions.  As of the last day of each Interim Offering Period the amount then
in the Participant's Plan Account will be divided by the Purchase Price and the
amount in the Participant's Plan Account shall be used to purchase the number
of whole shares of Stock which result.  Share certificates representing the
number of shares of Stock so purchased shall be issued and delivered to the
Participant as soon as reasonably practicable after the close of each Interim
Offering Period.  Any amount remaining in the Participant's Plan Account at the
end of an Offering Period after deducting the amount of the Purchase Price for
the number of whole shares issued to the Participant shall remain in the
Participant's Plan Account, without any accrual of

Employee Stock Purchase Plan (1994)



interest, and shall be applied against the purchases to be made during the next
Interim Offering Period.

                 (i)      WITHDRAWAL.  A Participant may elect to withdraw from
participation in the Plan at any time up to the last day of an Interim Offering
Period by filing the prescribed form with the Committee.  At the time of
withdrawal, the amount credited to the Participant's Plan Account will be
refunded in cash, without interest.  Upon withdrawal from the Plan, the
accumulated payroll deductions shall be returned to the withdrawn Participant
and the withdrawn Participant's interest in the Plan shall terminate.  In the
event a Participant voluntarily elects to withdraw from the Plan, such
Participant may not resume participation in the Plan until after the expiration
of one complete Interim Offering Period; provided, however, notwithstanding the
duration of any Interim Offering Period, any officer or director of the Company
participating under the Plan may not resume participation in the Plan for at
least six (6) months after his or her withdrawal.  Re-enrollment in the Plan
shall be made in the same manner as set forth above for initial participation
in the Plan.

                 (j)      PRO RATA ALLOCATION.  In the event that the aggregate
number of shares which all Participants elect to purchase during an Interim
Offering Period shall exceed the number of shares remaining available for
issuance under the Plan, the number of shares to which each Participant shall
become entitled shall be determined by multiplying the number of shares
available for issuance by a fraction, the numerator of which is the sum of the
number of shares the Participant has elected to purchase and the denominator of
which is the sum of the number of shares which all Participants have elected to
purchase.

         6.      EFFECT OF TERMINATION OF EMPLOYMENT.  Termination of a
Participant's employment for any reason, including retirement or death, or the
failure of a Participant to remain an Eligible Employee shall be treated as a
withdrawal under the Plan.  In the event of the Participant's death, the refund
of the Participant's Plan Account shall be paid, without interest, to the
representative of the Participant's estate.  A transfer by a Participant from
the Company to a Subsidiary, from one Subsidiary to another, or from a
Subsidiary to the Company shall not be treated as a termination of employment.

         7.      RIGHTS NOT TRANSFERABLE.

                 The rights or interests of any Participant in the Plan, in any
Option granted under the Plan, or in any Stock or moneys to which he or she may
be entitled under the Plan, shall not be transferable by voluntary or
involuntary assignment or by operation of law, or by any other manner otherwise
than by will or the applicable laws of descent and distribution.  If the
Participant





                                       5

ADAC Laboratoires

Employee Stock Purchase Plan (1994)



shall in any manner attempt to transfer, assign or otherwise encumber his or
her rights or interests under the Plan, other than by will, such act shall be
treated as a withdrawal from the Plan.

         8.      RECAPITALIZATION, ETC.

                 Subject to any required action by the shareholders of the
Company, the number of shares of Stock covered by each Option under the Plan
which has not yet been exercised and the number of shares of Stock which have
been authorized for issuance under the Plan but have not yet been placed under
an Option (collectively the "Reserves"), as well as the price per share of
Stock covered by each Option under the Plan which has not yet been exercised,
shall be proportionately adjusted for any increase or decrease in the number of
issued shares of Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of Stock, or any other increase or
decrease in the number of shares of Stock 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 issue by the Company of
the 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 of Stock
subject to an Option.

                 In the event of the proposed dissolution or liquidation of the
Company, the Offering Period will terminate immediately prior to the
consummation of such proposed action, unless otherwise provided by the Board.
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 Option under the Plan shall be assumed or an equivalent option shall be
substituted by such successor corporation, unless the Board determines, in the
exercise of its sole discretion and in lieu of such assumption or substitution,
that the Participant shall have the right to exercise the Option as to all of
the optioned Stock, including shares as to which the Option would not otherwise
be exercisable.  If the Board makes an Option fully exercisable in lieu of
assumption or substitution in the event of a merger or sale of assets, the
Board shall notify the Participant that the Option shall be fully exercisable
for a period of thirty (30) days from the date of such notice, and the Option
will terminate upon the expiration of such period.

                 The Board may also, if it so determines in the exercise of its
sole discretion, make provision for adjusting the Reserves, as well as the
price per share of Stock covered by each outstanding Option, in the event that
the Company effects one or more reorgani-

zations, recapitalization, rights offerings or other increases or reductions of
shares of its outstanding Stock, and in the event of the Company being
consolidated with or merged into any other corporation.

         9.      LIMITATION ON STOCK OWNERSHIP.

                 Notwithstanding any provision herein to the contrary, no
Participant shall be granted a right to purchase Stock pursuant to Section 5 if
such Participant, immediately after electing to purchase such Stock, would own
Stock possessing five percent (5%) or more of the total combined voting power
or value of all classes of stock of the Company or any parent or Subsidiary of
the Company, or (ii) if under the terms of the Plan the rights of the employee
to purchase Stock under this and all other qualified employee stock purchase
plans of the Company or its Subsidiaries would accrue at a rate that exceeds
$25,000 of fair market value of such Stock (determined at the time such right
is granted) for each calendar year for which such right is outstanding at any
time. For purposes of this Section 9, ownership of Stock shall be determined by
the attribution rules of Section 424(d) of the Code and Participants shall be
considered to own any Stock which they have a right or option to purchase under
this or any other plan.

         10.     RIGHTS AS AN EMPLOYEE.

                 Nothing in the Plan shall be construed to give any Participant
the right to remain in the employ of the Company or a Subsidiary or to affect
the right of the Company and its Subsidiaries or the Participant to terminate
such employment at any time with or without cause.

         11.     RIGHTS AS A SHAREHOLDER.

                 A Participant shall have no rights as a shareholder with
respect to any shares of Stock he or she may have a right to purchase under the
Plan until the date of issuance of a stock certificate to such Participant for
shares issued pursuant to the Plan.

         12.     AMENDMENT OR TERMINATION OF THE PLAN.

                 The Board of Directors shall have the right to amend, modify
or terminate the Plan at any time without notice, provided that no
Participant's existing rights are adversely affected thereby, and provided
