aggregate Fair Market Value of all stock covered by Incentive 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 its Parent or a Subsidiary of the
Company.

9.  NO CONTRACT OF EMPLOYMENT.
    --------------------------

    Unless otherwise expressed in a writing signed by an authorized officer of
the Company, all Employees of the Company are hired for an unspecified period of
time and are considered to be "at-will employees."  Nothing in this Plan shall
confer upon any Participant the right to continue in the employ of the Company,
its Parent or any Subsidiary, nor shall it limit or restrict in any way the
right of the Company, its Parent or any such Subsidiary to discharge the
Participant at any time for any reason whatsoever, with or without Cause.

10. NO RIGHTS AS A SHAREHOLDER.
    -------------------------- 

    A Participant shall have no rights as a shareholder with respect to any
shares of Common Stock subject to an Option.

11. NONTRANSFERABILITY OF OPTIONS; DEATH OF PARTICIPANT.
    --------------------------------------------------- 

    No Option acquired by a Participant under the Plan shall be assignable or
transferable by a Participant, other than by will or the laws of descent and
distribution, and such Options are exercisable, during his lifetime, only by
Optionee; provided, however, that any option agreement issued under the Plan may
provide for the designation of a beneficiary of the Optionee (which may be an
individual or trustee) who may exercise the Option after the Optionee's death
and enjoy the economic benefits thereof, subject to the consent of Optionee's
spouse where required by law.  Subject to Section 7(e), in the event of
Optionee's death, the Option may be exercised by the personal representative of
the Participant's estate or, if no personal representative has been appointed,
by the successor(s) in interest determined under the Participant's will or under
the applicable laws of descent and distribution.

Participants's will or under the applicationable lawas of descent and 
distribution.

12.  LIQUIDATION OF THE COMPANY.  In the event of a proposed dissolution or
     --------------------------                                            
liquidation of the Company, the Option shall terminate immediately prior to the
consummation of such proposed action, unless otherwise provided by the Board.
The Board may, in the exercise of its sole discretion in such instances, declare
that any Option shall terminate as of a date fixed by the Board and give each
Optionee the right to exercise his Option as to all or any part of the Shares
covered by an Option, including Shares as to which the Option would not
otherwise be exercisable.

13.  CHANGES OF CONTROL; OTHER EVENTS.  In the event of a proposed sale of all
     --------------------------------                                         
or substantially all of the assets of the Company (other than a sale or transfer
to a subsidiary or parent corporation of the Company), the merger or
consolidation of the Company with or into another corporation in a transaction
in which the Company does not survive (other than a reincorporation to another
state), or a Change in Control as defined in Section 2(e) hereof, Options
granted under the Plan may provide for certain rights of the Option holder or,
if exercised, the shareholder.  Furthermore, upon the occurrence of any such
event (and except as stated to the contrary in any Option Agreement granted
under the Plan), all Options shall vest immediately and may be fully exercised
without regard to the normal vesting schedules.  Should an Option so become
immediately exercisable, the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of not less than ten (10) nor more than
sixty (60) days from the date of such notice and, if such Option shall not be
exercised, the Option shall terminate upon the expiration of such period and be
of no further force or effect.

14.  AMENDMENTS; DISCONTINUATION OF PLAN.
     ----------------------------------- 

     The Board may from time to time alter, amend, suspend or discontinue the
Plan, including, where applicable, any modifications or amendments as it shall
deem advisable for any reason, including satisfying the requirements of any law
or regulation or any change thereof; provided, however, that no such action
shall adversely affect the rights and obligations of any holder of an Option
then outstanding under the Plan; and provided further, that no such action
shall, without the approval of the shareholders of the Company, (a) materially
increase the maximum number of shares of Common Stock that may be made subject
to Options (unless necessary to effect the adjustments required by Section
6(b)), (b)  materially increase the benefits accruing to Participants under the

                                      11

 
Stock Option Plan (1995)
Community Health Computing Corp.



Plan, or (c) materially lessen the requirements as to eligibility for
participation in the Plan.  No such amendment shall materially adversely affect
the rights of any Participant under any Option previously granted without such
Participant's prior consent.

15.  REGISTRATION OF OPTIONED SHARES.
     ------------------------------- 

     The Options shall not be exercisable unless the purchase of such Optioned
Shares is pursuant to an applicable effective registration statement under the
Securities Act of 1933, as amended, or unless, in the opinion of counsel to the
Company, the proposed purchase of such Optioned Shares would be exempt from the
registration requirements of the Securities Act of 1933, as amended.

16.  WITHHOLDING TAXES; SATISFIED BY WITHHOLDING OPTIONED SHARES.
     ----------------------------------------------------------- 

     (a) GENERAL. The Company, its Parent or any Subsidiary may take such
         -------                                                           
steps as it may deem necessary or appropriate for the withholding of any taxes
which the Company, its Parent or any Subsidiary is required by law or regulation
of any governmental authority, whether Federal, state or local, do mestic or
foreign, to withhold in connection with any Option including, but not limited
to, requiring the Optionee to pay such tax at the time of exercise or the
withholding of issuance of shares of Common Stock to be issued upon the exercise
of any Option until the Participant reimburses the Company for the amount the
Company is required to withhold with respect to such taxes, or, at the Company's
sole discretion, cancelling any portion of such issuance of Common Stock in any
amount sufficient to reimburse itself for the amount it is required to so
withhold.

     (b) SATISFYING TAXES BY WITHHOLDING OPTIONED SHARES.  Option Agreements
         -----------------------------------------------                    
under the Plan may, at the discretion of the Board, 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 or exercise, would be equal to the total withholding
obligation of the Optionee for the exercise of such Option; provided, however,
that if the Company is a corporation any of whose outstanding securities are
then registered under the Securities Exchange Act of 1934, 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
Shares 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 issues a news release
containing the operating results of a fiscal quarter or fiscal year and ending
on the twelfth 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 (unless notice to the
contrary is provided to the Company) be operative for all Option exercises which
occur during the twelve-month period following election.

17.  EFFECTIVE DATE AND TERM OF PLAN.
     ------------------------------- 

     The Plan is effective as of the date of adoption by the Board and Options
may be granted at any time on or after such date; provided, however, that (i)
the Plan shall terminate if the shareholders of the Company do not approve and
adopt it within twelve (12) months of such date and (ii) no Option shall be
effective unless an appropriate qualification or other approval of the Plan is
received, if necessary, from any state securities law adminis trator who may
have jurisdiction with respect thereto.  No Options shall be granted subsequent
to ten (10) years after the effective date of the Plan; however, Options
outstanding subsequent to ten years after the effective date of the Plan shall
continue to be governed by the provisions of the Plan until exercised or
terminated in accordance with the Plan or the respective Option Agreements.

               (ii)  "Cause" shall mean any of the following: (a) gross and
willful failure, after 30 days' written warning, to discharge the normal
employment duties required of the employee, (b) theft or other misappropriation
of Company property, trade secrets or other intellectual property rights and use
thereof for non-employee purposes or (c) commission of a crime such that the

partially disabled shall not be deemed "Cause" herein.

               (iii) "CHC" shall mean Community Health Computing Corp., a
Delaware corporation.

months; (ii) any "person" or "group" (as defined in or pursuant to Sections
13(d) and 14(d) of the Securities Act of 1934, as amended, (the "Exchange Act"),
becomes the "beneficial owner" (as defined in Rule 13(d) 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; or (iii) the Company or any of its
subsidiaries sells, through merger, assignment or otherwise, in one or more

the following formula: (a) the net income before interest expense and federal
income taxes based on net income ("EBIT") of CHC for the four fiscal quarters
ending immediately prior to a Change of Control divided by the EBIT of ADAC and

outstanding shares of convertible preferred stock of the Company may be
converted.

year after the shares are transferred to Optionee.

               (x)   "Net Intrinsic Value" of an Option shall mean the
difference between (a) the Fair Market Value per CHC Share and (b) the Option
exercise price, multiplied by the number of shares represented by the Unvested
Portion of an Option.

     3.   METHOD OF EXERCISE AND PAYMENT.
          ------------------------------

          A.   EXERCISE.  This Option may be exercised from time to time, in

whole or in part, to the extent exercisable, only by delivery to an officer of
the Company of the original of this Option with an appropriate Notice of
Exercise duly signed by the holder, together with the full purchase price of the
shares purchased pursuant to the exercise of the Option; provided, however, that
this Option may not be exercised if such exercise would violate any law or
governmental order or regulation.  If the offer and sale of the shares subject

purchased pursuant to any exercise shall be made in full at the time of such
exercise in cash or by check payable to the order of the Company or, if approved

promissory note is tendered, such note shall bear interest at an interest rate
determined by, and shall be subject to such terms and conditions as are
prescribed by, the Board as set forth in the form of promissory note then

          B.   WITHHOLDING.  Optionee agrees to have withheld from any
               -----------                                            
remuneration payable to him by the Company and/or to pay to the Company, at the
time of exercise of the Option, an amount which is required to be withheld or
paid pursuant to any Federal, State or local tax or revenue laws or regulations,
as may be determined by the Company.  If approved in advance by the Board of
Directors, the Optionee may satisfy such tax withholding by instructing the
Company to withhold such number of option shares exercised which, when valued at
fair market value as determined by the Board of Directors on the date of
Exercise, equal the total tax obligations required to be withheld.

     4.   NON-TRANSFERABILITY.  This Option shall not be transferred, sold,
          -------------------                                               
pledged, assigned, hypothecated, or disposed of in any manner by Optionee other
than by will or the laws of descent and distribution to the extent hereinafter
set forth.  This Option may be exercised during the holder's lifetime only by
the holder hereof or, upon the holder's legal incapacity to act on his/her own
behalf, by the holder's conservator or other lawful representative.  The Option
shall be null and void and without effect upon any attempted assignment or
transfer, except as hereinabove provided, including without limitation, any
purported assignment, whether voluntary or by operation of law, pledge,
hypothecation or other disposition contrary to the provisions hereof, or levy of
execution, attachment, trustee process or similar process, whether legal or
equitable, upon the Option.

     5.   TERMINATION.  To the extent that this Option shall not have been
          -----------                                                     
exercised in full prior to its termination or expiration date, whichever shall
be sooner, it shall terminate and become void and of no effect.

     6.   CESSATION OF CONTINUOUS STATUS -- TERMINATION, RETIRE MENT, DEATH OR
          --------------------------------------------------------------------
DISABILITY; TERMINATION "FOR CAUSE."  If the Optionee shall voluntarily or
- ------------------------------------                                      
involuntarily cease his/her Continuous Status (as such term is defined in the
Plan) (hereinafter referred to as a "Termination"), the Option shall terminate
forthwith, except that the Optionee shall have three (3) months (or such longer
period as the Board may approve) following the Termination to exercise this
Option or any portion thereof which the Optionee could have exercised on the
date of Termination; provided, however, that if the Termination is due to (i)
retirement by the Optionee on or after attaining the age of sixty-five (65)
years, (ii) the disability of the Optionee or (iii) the death of the Optionee,
the Optionee or the representative of the estate of the Optionee shall have the
privilege of exercising the entire unexercised vested portion of this Option,
provided that such exercise be accomplished (a) prior to the expiration of this
Option and (b) either within three (3) months of the Optionee's retirement,
within twelve (12) months of the Optionee's disability, or within twelve (12)
months after the date of death of the Optionee,

                                       5

 
Stock Option Agreement 
Community Health Computing Corp.

as the case may be.  Notwithstanding any of the foregoing, if the Termination is
for Cause (as such term is defined herein) or Optionee breaches (before or after
termination) any of his duties under this Agreement, the existence of which
shall be determined by the Board of Directors or any Committee established to
administer the Plan (such decision to be made by the Board or Committee in its
sole discretion and which determination shall be conclusive), this Option shall
terminate immediately upon the Termination and the Optionee in such event shall
have no right after such Termination to exercise any unexercised Option which
he/she might have exercised on or prior to the Termination.

     7.   STOCK SPLITS AND CAPITAL ADJUSTMENTS.  If, prior to the complete
          ------------------------------------                            
exercise of this Option, there shall be declared and paid a stock dividend upon
the Common Stock of the Company or if such stock shall be split up, converted,
exchanged or reclassified, this Option, to the extent that it has not been
exercised, shall entitle the Optionee, upon the future exercise of this Option,
to such number and kind of securities or other property, subject to the terms of
the Option, to which the Optionee would be entitled had he/she actually owned
the stock subject to the unexercised portion of the Option at the time of the
occurrence of such stock dividend, split up, conversion, exchange,
reclassification or substitution; and the aggregate purchase price upon the
future exercise of the Option shall be the same as if shares of Common Stock of
the Company originally optioned were being purchased as provided herein.

     8.   CHANGE IN CONTROL PROVISIONS.
          ---------------------------- 

          A.   UPON A CHANGE OF CONTROL OF THE COMPANY, THE FOLLOWING EVENT
               ------------------------------------------------------------
SHALL OCCUR:
- ----------- 

          The Company shall become obligated to pay to Optionee a sum equal to
the Net Intrinsic Value of the Unvested Portion of his or her Option, but
subject to the following terms and conditions:  Such sum shall be paid to
Optionee, with interest thereon at a rate of 6% per annum, immediately upon the
earliest to occur of the following events:  (a) Optionee has completed 12
additional consecutive months of employment (commencing from the date of the
Change of Control); (b) Optionee's employment is terminated by the Company or
its parent corporation for any reason other than Cause; (c) Optionee's
Compensation Package is reduced; (d) Optionee's duties or responsibilities are
materially reduced in scope or importance or (e) Optionee's place of employment
is changed to a location in excess of ten miles beyond Optionee's then-existing
place of employment.  Pending a determination of Optionee's entitlement to such
sum, it shall be retained by the Company in a separate segregated trust or
escrow account at a bank or other Federally-insured savings institution and
shall be unavailable for use or borrowing by the Company or its affiliates.

          B.   UPON A CHANGE OF CONTROL OF EITHER CHC OR ADAC, THE FOLLOWING
               -------------------------------------------------------------
EVENT SHALL OCCUR:
- ----------------- 

          Each person who owns shares of Company Common Stock as a result of the
exercise of an Option (an "Exchanging Shareholder") may elect to exchange such
shares for that number of shares of ADAC Common Stock having a market value
equal to the Fair Market Value per CHC Share multiplied by the number of shares
of the Company's Common Stock being tendered for exchange.  The market value of
a share of ADAC Common Stock shall be based upon such share's closing price on
the date of the Change of Control; provided, however, that if ADAC Common Stock
is not publicly traded on such date, or if on such date ADAC has been merged
with another entity or 80% or more of its assets or shares have been sold to
another entity which is, in each such case, owned or controlled by persons other
than ADAC's previous shareholders, the Exchanging Shareholder may elect to
deliver his or her shares of Company Common Stock to ADAC or to the Company in
consideration for cash equal to the Fair Market Value per CHC Share multiplied
by the number of Company shares being tendered for exchange.  In order to
facilitate such exchange of shares, ADAC hereby agrees to prepare and file with
the Securities and Exchange Commission, and to use its best efforts to cause to
become effective, a Registration Statement on Form S-3 (or similar form having
the same economic effects) covering all ADAC shares exchanged for Company Common
Stock, and to maintain its effectiveness for a period of two years; all fees
and expenses incurred in connection therewith shall be borne by ADAC; and the
selling shareholders and ADAC shall enter into an appropriate indemnification
agreement whereby ADAC shall indemnify the selling shareholders against any
losses and expenses which may be incurred as a result of ADAC including any
statement or representation in the Registration Statement which is materially
false or misleading or omitting to include therein any statement the omission of
which results in the Registration Statement being false or misleading in any
material respect.

     9.   RESTRICTIONS ON TRANSFER OF STOCK -- RIGHT OF FIRST REFUSAL.
          ----------------------------------------------------------- 

          A.   RESTRICTIONS.  Optionee agrees that he/she will not, directly or
               ------------                                                    
indirectly, sell, pledge, give, bequeath, transfer, assign or dispose
(collectively, a "transfer") of any Common Stock (or any interest therein),
acquired pursuant to the exercise of the Option, except as permitted by this
Agreement, or as may be specifically authorized by the Board of Directors of the
Company in its  sole discretion, or in accordance with the following:  If
Optionee shall have received a bona fide arms' length written offer (a "Bona
Fide Offer") which Optionee desires to accept from an independent party
unrelated to Optionee (the "Third Party") for the purchase of such Common Stock,
such Option Holder shall give a notice in writing (the "Sale Notice") to the
Company setting forth

                                       7

 
Stock Option Agreement 
Community Health Computing Corp.

the material facts concerning the proposed transfer, including the name and
address of the Third Party and the price and terms of the Bona Fide Offer and be
accompanied by a copy of the Bona Fide Offer.  Upon the giving of the Sale
Notice, the Company or its assignee shall have the right to purchase all of the
Common Stock specified in the Sale Notice, said right to be exercised no later
than 30 business days after the giving of such Sale Notice or, if later, 15 days
after the determination of the fair market value (as defined below) of any non-
cash consideration offered by the Third Party by giving written notice of the
Company's (or its assignee's) election to purchase all of such Common Stock.
Upon receipt of such notice from the Company, the Company shall be obligated to
purchase, and such Optionee shall be obligated to sell to the Company such
Common Stock at the price and terms indicated in the Bona Fide Offer and the
closing of the purchase by the Company shall be held as soon as reasonably
practicable and, if the consideration offered by the Third Party in the Bona
Fide Offer consists of property other than cash, then the Company shall pay for
the Common Stock in cash in an amount equal to the fair market value of such
consideration.

          If the Company does not elect to purchase all of such Common Stock,
Optionee thereafter, at any time within a period of thirty (30) days from the
giving of said Sale Notice, may transfer all (but not less than all) of such
Common Stock to the Third Party at the price and terms contained in the Bona
Fide Offer, and the Third Party and such Common Stock shall thereafter be
subject to and be bound by all of the provisions of this Agreement and, as a
condition precedent to the completion of such transfer of Common Stock to such
Third Party, shall execute and deliver to the Company a written acknowledgement
to such effect in form and substance reasonably satisfactory to the Company,
except that the Company shall not be entitled to the "call" rights set forth in
this Section with respect to the shares of Common Stock acquired by the Third
Party; provided, however, that in the event Optionee has not so transferred said
Common Stock to the Third Party within said 30-day period, then said Common
Stock thereafter shall continue to be subject to all of the restrictions
contained in this Agreement.

          For purposes of this Section, "fair market value" of non-cash
consideration means the cash-equivalent value of the non-cash consideration as
determined in good faith by the Board of Directors of the Company.  Upon
delivery of notice of such fair market value to Optionee (which shall indicate,
in a general fashion, the factors considered by the Board in determining such
amount), such Optionee shall have ten business days in which to notify the
Company in writing of any disagreement.  If written notice is given of a
disagreement, the Company and Optionee shall mutually agree upon an independent
appraiser experienced in making valuations of such sort which shall make a
determination of the fair market value of the non-cash consideration.  Such
determination shall be final,

                                       8

 
Stock Option Agreement 
Community Health Computing Corp.


binding and non-appealable upon the Company and Optionee.  The cost and expenses
incurred in connection with the determination made by the independent appraiser
shall be borne (i) by the Company if the independent appraiser makes a higher
determination of fair market value than the Board of Directors of the Company,
or (ii) by Optionee if the independent appraiser makes the same or a lower
determination of such fair market value.

          B.   PERMISSIBLE TRANSFERS TO RELATED TRANSFEREES. Notwithstanding
               --------------------------------------------                 
anything to the contrary contained above in this Section, Optionee may transfer
such Optionee's Common Stock without restriction to such Optionee's Related
Transferees (as defined herein), provided that each such Related Transferee
shall first execute a written consent in form and substance reasonably
satisfactory to the Company to be bound by all of the provisions of this
Agreement.  The "Related Transferees" of an Optionee shall consist of Optionee's
spouse, Optionee's adult children, trusts established solely for the benefit of
Optionee's spouse or Optionee's minor children and, in the event of death,
Optionee's personal representatives (in their capacities as such), estate and
named beneficiaries.  In the event of any transfer by an Optionee to a Related
Transferee of all or any part of such Optionee's Common Stock (or in the event
of any subsequent transfer by any such Related Transferee to another Related
Transferee of the original Optionee), such Related Transferee(s) shall receive
and hold said Common Stock subject to the terms of this Agreement and the rights
and obligations hereunder, and such Related Transferee shall be deemed to be an
Optionee for the purposes of this Agreement.  There shall be no further transfer
of such Common Stock by a Related Transferee except between and among such
Related Transferees, the Optionee to whom such Related Transferee is related and
the other Related Transferees of such Optionee, or except as permitted by this
Agreement.

     10.  COMPANY'S "CALL" OPTIONS.
          ------------------------ 

          A.   COMPANY'S "CALL" OPTION.  Upon the (i) voluntary or involuntary
               -----------------------                                        
termination of Optionee's employment with the Company for any reason or (ii)
death of Optionee, (collectively a "Callable Event"), subject to the provisions
of Section 11 and this Section, the Company may, at its option, exercisable by
   ----------                                                                 
written notice (a "Call Notice") delivered to such Optionee within 90 days after
the applicable Callable Event (or, in the event the applicable Callable Event is
the death of an Optionee, within 30 days after the appointment and qualification
of the deceased Optionee's personal representative, if later), elect to
purchase, and, upon the giving of such Call Notice, the Company shall be
obligated to purchase and such Optionee (or, as applicable, the Related
Transferee or Optionee's personal representative) (the "Seller") shall be
obligated to sell, all or any portion of the shares of Company Common Stock
theretofore acquired by such Optionee (and his Related

                                       9

 
Stock Option Agreement 
Community Health Computing Corp.


Transferees, if any) pursuant to the exercise of Options hereunder and owned at
the time of the Call Purchase Event at a per share purchase price equal to the
Fair Market Value per CHC Share.  The Company need not treat all option holders
of the Company in a similar manner, and may exercise its call rights hereunder,
partially or fully, with respect to some optionees and not others, and for any
reason it deems appropriate.

          B.   DEFINITIONS OF FAIR MARKET VALUE PER CHC SHARE.  For purposes of
               ----------------------------------------------                  
this Section, the term "Fair Market Value per CHC Share" shall be based upon the
definition thereof set forth in Section 1.A(viii) hereof; provided, however,
that for purposes of this Section 10 only, the Board of Directors of the Company
shall not be bound by such definition if it determines, in good faith, that to
do so would result in a per share valuation that would not reflect the true fair
market value of the Company's Common Stock.

          C.   CLOSING TERMS.  The closing for all purchases and sales of Common
               -------------                                                    
Stock provided for in this Section 10 shall be at the principal executive
offices of the Company as soon as reasonably practicable after the giving of
the Call Notice.  The purchase price for the purchase and sale of Common Stock
pursuant to the provisions hereof shall be paid in cash, by certified or
official bank check.  The Seller of shares of Common Stock sold pursuant to this
Section shall cause such shares to be delivered to the Company at the closing
free and clear of all liens, charges or encumbrances of any kind.  Such Seller
shall take such action as the Company shall request as necessary to transfer the
shares to the Company, free and clear of all liens, charges and encumbrances
incurred, voluntarily or involuntarily, by or through Seller.

     11.  TERMINATION AND LAPSE OF CERTAIN RIGHTS AND RESTRICTIONS.
          -------------------------------------------------------- 

          A.   The Company's right of first refusal upon any proposed transfer
set forth in Section 9 and the Company's call rights set forth in Section 10
             ---------                                            ----------
shall lapse and be of no further effect with respect to shares of the Common
Stock acquired by an Optionee pursuant to the exercise of Options hereunder upon
the earlier to occur of:  (i) the completion of the first underwritten,
registered public offering of Common Stock of the Company; or (ii) the
consummation of a sale of substantially all of the assets of the Company and its
subsidiaries taken as a whole or a sale of substantially all of the outstanding
shares of capital stock of the Company.

     12.  COMPLIANCE WITH SECURITIES LAWS.
          ------------------------------- 

          A.   POSTPONE ISSUANCE.   Notwithstanding any provision of this Option
               -----------------                                                
to the contrary, the Company may postpone the issuance and delivery of shares of
Company Common Stock upon any exercise of this Option until one of the following
conditions shall be met:

                                      10

 
Stock Option Agreement 
Community Health Computing Corp.


               (i)  The shares with respect to which such Option has been
exercised are at the time of the issue of such shares effectively registered
under applicable Federal and state securities laws now in force or hereafter
enacted or amended; or

               (ii) Counsel for the Company shall have given an opinion that
registration of such shares under applicable Federal and state securities laws,
as now in force or hereafter enacted or amended, is not required.

          B. INVESTMENT REPRESENTATION.  In the event that for any reason the
             -------------------------                                       
shares to be issued upon exercise of the Option shall not be effectively
registered under the Securities Act of 1933 (the "1933 Act"), upon any date on
which the Option is exercised in whole or in part, the Company shall be under no
further obligation to issue shares covered by the Option unless the Optionee
shall give a written representation to the Company, in form satisfactory to the
Company, that such person is acquiring the shares issued pursuant to such
exercise of the Option for investment and not with a view to, or for sale in
connection with, the distribution of any such shares, and that he/she will make
no transfer of the same except in compliance with the 1933 Act and the rules and
regulations promulgated thereunder and then in force, and in such event the
Company may place an "investment legend" upon any certificate for the shares
issued by reason of such exercise.

          C.   DISPOSITION OF STOCK ACQUIRED UPON EXERCISE.  In addition to the
               -------------------------------------------                     
other restrictions provided in this Agreement, Optionee agrees that prior to
making any disposition or transfer of any Common Stock acquired pursuant to the
exercise of this option Optionee shall give twenty (20) days' prior written
notice to the Company describing the manner of such proposed transfer.  Optionee
further agrees that he/she will not effect such proposed transfer until either
(i) Optionee has provided to the Company, if so requested by the Company, an
opinion of counsel reasonably satisfactory in form and substance to the Company
that such proposed transfer is exempt from registration under the 1933 Act and
any applicable state securities laws, or (ii) a registration statement under the
1933 Act covering such proposed disposition has been filed by the Company
(although the Company is under no obligation to file any registration statement)
under the 1933 Act and has become effective and compliance with applicable state
securities laws has been effected.  The Company agrees that it will respond as
promptly as reasonably practicable to any notice of sale given hereunder.

          D.   NO TRADING MARKET; NO REGISTRATION OBLIGATION.  Each Optionee
               ---------------------------------------------                
acknowledges that no trading market for the Company's Common Stock exists and,
as a result, Optionee may be unable to sell any of the Common Stock acquired
upon the exercise of the

                                      11

 
Stock Option Agreement 
Community Health Computing Corp.


Options for the foreseeable future.  Further, the Company has no obligation to
register any of such Common Stock.

          E.   LEGEND ON CERTIFICATES.  Each stock certificate of the Company
               ----------------------                                        
issued to represent any of the shares of Common Stock acquired pursuant to the
exercise of Options shall bear the following (or substantially equivalent)
legends on the face or reverse side thereof:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"),
          OR THE SECURITIES LAWS OF ANY JURISDICTION.  SUCH SECURITIES MAY NOT
          BE OFFERED, SOLD, OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED
          EXCEPT PURSUANT TO (I) A REGISTRATION STATEMENT WITH RESPECT TO SUCH
          SECURITIES THAT IS EFFECTIVE UNDER SUCH ACT OR APPLICABLE STATE
          SECURITIES LAW, OR (II) ANY EXEMPTION FROM REGISTRATION UNDER SUCH
          ACT, OR APPLICABLE STATE SECURITIES LAW, RELATING TO THE DISPOSITION
          OF SECURITIES, INCLUDING RULE 144, PROVIDED AN OPINION OF COUNSEL IS
          FURNISHED, REASONABLY SATISFACTORY IN FORM AND SUBSTANCE TO THE
          COMPANY, THAT AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
          ACT AND/OR APPLICABLE STATE SECURITIES LAW IS AVAILABLE.

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED,
          SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS
          SUCH TRANSFER COMPLIES WITH THE PROVISIONS OF A STOCK OPTION
          AGREEMENT TO WHICH THE HOLDER HEREOF IS A PARTY, A COPY OF WHICH IS ON
          FILE AT THE OFFICE OF THE COMPANY.

Any stock certificate issued at any time in exchange or substitution for any
certificate bearing such legends (except a new certificate issued upon the
completion of a public distribution of Common Stock represented thereby) shall
also bear such (or substantially equivalent) legends, unless the Common Stock
represented by such certificate is no longer subject to the provisions of this
Agreement and in the opinion of counsel for the Company the Common Stock
represented thereby need no longer be subject to restrictions pursuant to the
1933 Act or applicable state securities law.  The Company shall not be required
to transfer on its books any certificate for Common Stock in violation of the
provisions of this Agreement.  The failure of the Company to affix such a legend
to the certificate shall not release or waive Optionee's obligations under this
Agreement.

exercise of this Option which occurs within either twelve (12) months following
the date of exercise or twenty-four (24) months following the date of grant.

Option, it shall be exercisable in accordance with the above schedule set forth
in  Section 2 hereof, but in no event shall it be exercised to the extent that
    ---------

its parent or a subsidiary of the Company which are exercisable for the first
time during the same calendar year, exceeds $100,000.

     14.  NO AGREEMENT OF EMPLOYMENT.  Neither the grant of this Option nor this
          --------------------------                                            
Agreement shall be deemed to create any agreement with, or obligation by, the
Company to employ the Optionee for any period of time, it being understood that
employment is strictly "at will" in the absence of any written agreement to the
contrary and, in the absence of such written agreement, such person may be
terminated by the Company at any time, with or without cause.

     15.  ASSIGNMENT OF INVENTIONS, ETC.; NON-DISCLOSURE OF CONFIDENTIAL
          ---------------------------------------------------------------
INFORMATION.  As further consideration for the issuance of the Option, the

Optionee, if he is an employee of the Company, agrees as follows:

          A.   ASSIGNMENT OF INVENTIONS.  Any and all trade secrets, inventions
               ------------------------                                        
and proprietary information which either (i) relates at the time of conception
or reduction to practice to the Company or its business, or actual or
demonstrably anticipated research or development of the Company or (ii) results
from any work performed by the Optionee for the Company is hereby assigned to,
and shall become the absolute property of, the Company and shall at all times
and for all purposes be regarded as acquired and held by the Optionee in a
fiduciary capacity for the sole benefit of the Company, and the Optionee agrees
that, upon request, he will promptly make all disclosures, execute all
assignments, instruments and papers, and perform all acts whatsoever necessary
or desired by the Company to vest and confirm in it, its successors, assigns and
nominees, all rights created or contemplated by this subparagraph A and which
may be necessary or desirable to enable the Company, its successors, assigns,
and nominees to secure and enjoy the full benefits and advantages thereof.

Stock Option Agreement 
Community Health Computing Corp.


          B.   NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  The Optionee shall
               -----------------------------------------                     
not, during his employment by the Company or at any time thereafter, directly or
indirectly use, divulge, furnish or make accessible to anyone other than the
Company, its directors and officers other than in the regular course of the
business of the Company or any of its subsidiaries, any knowledge or information
with respect to (i) confidential, secret or proprietary plans, data (including
cost data), specifications, procedures and techniques, methods, inventions,
software, firmware, source codes, technology, "knowhow," or other similar
material or data relating to the business, products, services (whether existing
or under development) or activities of the Company or its subsidiaries, (ii)
any confidential business plans or surveys of the Company or its subsidiaries,
(iii) any other confidential or secret aspect of the business, products,
services or activities of the Company or its subsidiaries, or (iv) any customer
usages and requirements or any customer lists of the Company or its
subsidiaries.  The Optionee shall not, upon leaving the employ of the Company,
without the prior written consent of an executive officer of the Company, take
with him any data, customer lists, reports, studies, compilations, business
plans, presentations/proposals, letters, memoranda, notes or other writings or
documents whatever, or copies thereof, which reflect or deal with any of the
confidential information described in this Section.

          C.   REMEDIES.  The  Optionee  acknowledges that a breach of the
               --------                                                   
provisions of this Agreement will cause the Company irreparable injury for
which the Company cannot be reasonably or adequately compensated in damages. The
Company shall, therefore, be entitled, in addition to all other remedies
available to it, to injunctive and/or other equitable relief to prevent a breach
of this Agreement, or any part of it, and to secure its enforcement.

     16.  SUBJECT TO PLAN.  This Option is issued subject and pursuant to the

provisions of the Plan, receipt of a copy of which the holder acknowledges.  A
determination of the Board of Directors or the Committee established pursuant to
the Plan as to any questions which may arise with respect to the interpretation
of the provisions of this Option and of the Plan shall be final.  The Board of
Directors or the Committee may authorize and establish such rules and
regulations, and revisions thereof, not inconsistent with the provisions of the
Plan, as it may deem advisable.  Any provision hereof which is contrary to the
terms and conditions of the Plan shall be superseded and governed by the Plan.

     17.  SEVERABILITY.  If any condition, term or provision of this Agreement
          ------------                                                        
is determined by a court to be illegal or in conflict with any law, state or
Federal, the validity of the remaining portions or provisions shall not be
affected, and the rights and obligations of the parties shall be construed and

provision determined to be unenforceable.

understanding and agreement between the parties hereto respecting the within
subject matter, and there are no representations, agreements, arrangements or
understandings, oral or written, between the parties hereto relating to the
subject matter of this Agreement that are not fully expressed herein.  The
