                                                          SHARES OF COMMON STOCK

                             MAI SYSTEMS CORPORATION

              INCORPORATED UNDER THE LAWS OF THE STATE OF DELAWARE

                           VOID AFTER FEBRUARY 2, 2011

     THIS CERTIFICATE evidences the right of Purchaser, for value received, to
purchase 25,000 shares of $.01 par value Common Stock of the Company (the
"Shares") at a price of thirty-six cents (US$0.36) per Share; subject, however,
to the terms and conditions hereinafter set forth.

1. Term of Warrants. The Warrants may be exercised only during a period
commencing on February 2, 2001 through the close of business on February 2, 2011
(the "Warrant Term") and may be exercised only in accordance with the terms and
conditions hereinafter set forth.

2. Exercise of Warrants. The Warrants shall be exercisable as follows:

     (a) Right to Exercise. From time to time during the Warrant Term, the
Purchaser shall have the right to exercise Warrants to purchase the maximum
number of Shares specified in the following table:

                                              Aggregate Maximum Number of Shares
        Portion of Warrant Term               for Which Warrants Are Exercisable
        -----------------------               ----------------------------------
February 2, 2001 through February 2, 2011                    25,000

<PAGE>   2

     (b) Method of Exercise; Payment; Issuance of New Warrant; Transfer and
Exchange. Subject to the provisions of Subsection (a) of this Section 2, the
Warrants may be exercised by the Purchaser, in whole or in part, by the
surrender of this Certificate, properly endorsed, at the principal office of the
Company, and by the payment to the Company by certified or cashier's check of
the then applicable Warrant Price (as such term is hereafter defined). In the
event of any exercise of the Warrants, certificates for the Shares so purchased
shall be delivered to the Purchaser within a reasonable time after the Warrants
shall have been so exercised, and unless the Warrants have expired, a new
certificate representing the right to purchase the number of Shares, if any,
with respect to which this Certificate shall not then have been exercised shall
also be issued to the Purchaser within such time. All such new certificates
shall be dated the date hereof and shall be identical with this Certificate
except as to the number of Shares issuable pursuant thereto.

     (c) Restrictions on Exercise. The Warrants may not be exercised if the
issuance of the Shares upon such exercise would constitute a violation of any
applicable federal or state securities

3. Stock Fully Paid; Reservation of Shares. The Company covenants and agrees
that all shares will, upon issuance and payment in accordance herewith, be fully
paid, validly issued and nonassessable. The Company further covenants and agrees
that during the Warrant Term the Company will at all times have authorized and
reserved for the purpose of issuance upon exercise of the Warrants at least the
maximum number of Shares as are issuable upon the exercise of the Warrant.

4. Adjustment of Purchase Price and Number of Shares. The number and kind of
securities purchasable upon the exercise of the Warrants and the Warrant Price
shall be subject to adjustment from time to time upon the happening of certain
events, as follows:

     (a) Consolidation or Merger. If the Company at any time while the Warrants
remain outstanding unexpired shall sell all or substantially all of the assets
of the Company to another corporation, merge, consolidate or reorganize the
Company with or into another corporation as a result of which the Company is not
the surviving corporation or as a result of which the outstanding shares of
Common Stock are exchange for or converted into cash or property or securities
not of the Company (any of which shall constitute a "Reorganization"), the
Company shall, at its option, either (i) make provision for the assumption of
the Warrants by the successor corporation or a parent or a subsidiary thereof
and the Warrants evidenced by this Certificate shall continue to vest in
accordance with the schedule set forth in Section 2(a) hereof or (ii) the
Company may declare, in the notice to be provided to the Purchaser pursuant to
Section 4(f) hereof, that the Warrants shall terminate on the effective date of
such Reorganization and, provided termination shall not have occurred prior to
the date of such Notice, give the Purchaser the right to exercise the Warrants
prior to the effective date of the Reorganization as to all or any of the
Shares, including any Shares as to which the Warrants would not otherwise be
exercisable pursuant to Section 2(a) hereof. Notwithstanding anything in this
Section 4(a) to the contrary, the prior sentence shall be inoperative and of no
force and effect if upon completion of any such Reorganization the stockholders
of the Company immediately prior to such event do not own at least fifty percent
(50%) of the equity interest of the corporation resulting from such
Reorganization and those Warrants which are unexercised shall expire upon the
completion of such Reorganization if the notice required by Section 4(f) hereof
has been duly given.

     (b) Reclassification. If the Company at any time while the Warrants remain
outstanding and unexpired shall reclassify or in any manner change the
securities then purchasable upon the exercise of the Warrants, then the number
of shares which were purchasable or would have become purchasable under the
warrants immediately prior to the reclassification shall be adjusted so that the
Purchaser shall be entitled to receive the number and kind of shares or other
securities of the Company which he would have owned or have been entitled to
receive after the consummation of the reclassification had the Warrants been
exercised immediately prior to the reclassification. An adjustment made pursuant
to this Section 4(b) shall become effective immediately after the date of the
reclassification, retroactive to the record date, if any.

                                       2

<PAGE>   3

     (c) Subdivision or Combination of Shares. If the Company at any time while
the Warrants remain outstanding unexpired shall subdivide or combine its Common
Stock, the Warrant Price shall be adjusted to that price determined by
multiplying the Warrant Price in effect immediately prior to such subdivision or
combination by a fraction (i) the numerator of which shall be the total number
of shares of Common Stock outstanding immediately prior to such subdivision or
combination and (ii) the denominator of which shall be the total number of
shares of Common Stock outstanding immediately after such subdivision or
combination.

     (d) Certain Dividends and Distribution. If the Company at any time while
the Warrants are outstanding and unexpired shall take a record of the holders of
its Common Stock for the purpose of:

          (i) Stock Dividends. Entitling them to receive a dividend payable in,
or other distribution without consideration of, Common Stock, then the Warrant
Price shall be adjusted to that price determined by multiplying the Warrant
Price in effect immediately prior to each dividend or distribution by a fraction
(A) the numerator which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend or distribution and (B) the
denominator of which shall be the total number of shares of Common Stock
outstanding immediately after such dividend or distribution; or

          (ii) Distribution of Assets, Securities, etc. Making any distribution
without consideration with respect to its Common Stock (other than a cash
dividend) payable otherwise than in its Common Stock, the Purchaser shall, upon
the exercise thereof, be entitled to receive in addition to the number of Shares
receivable thereupon, and without payment of any additional consideration
thereof, such assets or securities as would have been payable to him as owner of
that number of Shares receivable by exercise of the Warrants had he been holder
of record of such Shares on the record date for such distribution.

     (e) Adjustment of Number of Shares. Upon each adjustment in the Warrant
price pursuant to Subsections (d) or (d)(i) of this Section 4, the number of
Shares purchasable hereunder shall be adjusted to that number determined by
multiplying the number of Shares purchasable upon the exercise of the Warrants
immediately prior to such adjustment by a fraction, the numerator of which shall
be the Warrant price immediately prior to such adjustment and denominator of
which shall be the Warrant Price immediately following such adjustment.

     (f) Notice. In case at any time:

          (i) The Company shall pay any dividend payable in stock upon its
Common Stock or make any distribution, excluding a cash dividend, to the holders
of its Common Stock;

          (ii) The Company shall offer for subscription pro rata to the holders
of its Common Stock any additional shares of stock of any class or other rights;

          (iii) There shall be any reclassification of the Common Stock of the
Company, or consolidation or merger of the Company, with or sale of all or
substantially all of its assets to, another corporation; or

          (iv) There shall be a voluntary or involuntary of involuntary
dissolution, liquidation or winding up of the Company;

                                       3

<PAGE>   4

then, in any one or more of such cases, the Company shall give to the Purchaser
at least ten (10) days' prior written notice (or, in the event of notice
pursuant to Section 4(f)(iii), at least thirty (30) days' prior written notice)
of the date on which the books of the Company shall close or record shall be
taken for such dividend, distribution or subscription rights or for determining
rights to vote in respect to any such reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up. Such notice in accordance with the
foregoing clause shall also specify, in the case of any such dividend,
distribution or subscription rights, the date on which the holders of Common
Stock shall be entitled thereto, and such notice in accordance with the
foregoing clause shall also specify the date on which the holders of Common
Stock shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, consolidation, merger, sale,
dissolution, liquidation or winding up, as the case may be. Each such written
notice shall be given by first-class mail, postage prepaid, addressed to the
Purchaser at the address of the Purchaser as shown on the books of the Company.

     (g) No Change in Certificate. The form of this Certificate need not be
changed because of the adjustment in the Warrant Price or in the number of
Shares purchasable on its exercise. The Warrant Price or the number of Shares
shall be considered to have been so changed as of the close of business on the
date of adjustment.

5. Fractional Shares. No fractional Shares will be issued in connection with any
subscription hereunder, but in lieu of such fractional Shares, the Company shall
make payment therefor upon the basis of the fair market value of the Shares.

6. Non-transferability of Warrants. The Warrants may not be sold, pledged,
assigned, hypothecated, gifted, transferred or disposed of in any manner, in
whole or in part, without the prior written consent of the Company in its sole
discretion.

7. No Rights as Stockholder. The holder of the Warrants, as such, shall not be
entitled to vote or receive dividends or be considered a stockholder of the
Company for any purpose, nor shall anything in this Certificate be construed to
confer on such holder, as such, any rights of a stockholder of the Company or
any right to vote, give or withhold consent to any corporate action, to receive
notice of meetings of stockholders, to receive dividends or subscription rights
or otherwise.

8. Definitions. As used in this Certificate:

     (a) "Warrants" shall mean the rights evidenced by this Certificate.

     (b) "Warrant Price" shall mean thirty-six cents (US$0.36) as adjusted in
         accordance with Section 4 hereof.

                    AGREEMENT FOR NONQUALIFIED STOCK OPTIONS
                              FOR CLINICAL ADVISOR

     THIS OPTION AGREEMENT (the  "Agreement") is made and entered into effective
as of the __ day of ____, _____, by and between Atrion  Corporation,  a Delaware
corporation  (the  "Company"),  and  ____________________________,   a  Clinical
Advisor (the "Participant").

                              W I T N E S S E T H :
                              - - - - - - - - - -

     WHEREAS,  the  Participant is currently  serving as a Clinical  Advisor for
Quest Medical, Inc. ("Quest"), a wholly-owned subsidiary of the Company; and

     WHEREAS,  the Company desires to encourage the Participant to own shares of
common  stock of the Company  ("Shares")  and to give the  Participant  an added
incentive to advance the interests of the Company.

     NOW,  THEREFORE,  for and in  consideration  of the  premises,  the  mutual
promises  and  covenants   herein   contained,   and  other  good  and  valuable
consideration,  the  receipt,  adequacy  and  sufficiency  of which  are  hereby
acknowledged, the parties hereto do hereby agree as follows:

     1. Subject to the execution of this  Agreement,  the Company has granted to
the  Participant  an option (the  "Option")  to purchase  from the Company  such
number of whole  Shares as is set forth on  Exhibit A attached  hereto  from the
authorized and unissued common stock of the Company,  or from the treasury stock
of the Company, at and for the price set forth on Exhibit A attached hereto (the
"Option Price"). The Option has been designated as a nonqualified stock option.

     2.  The  Option  shall be  exercised  by  delivery  to the  Company  at its
principal office of written notice of the  Participant's  intent to exercise the
Option with respect to the number of Shares then being purchased, accompanied by
payment in full to the Company of the amount of the Option  Price for the number
of Shares then being  purchased.  The Option  Price upon  exercise of the Option
shall be payable to the Company (a) in cash or its equivalent,  (b) by tendering
previously  acquired  Shares  having an aggregate  Fair Market Value (as defined
below) at the time of exercise  equal to the aggregate  Option Price or (c) by a
combination  of (a) and (b).  The Option  Price  shall be paid  directly  by the
Participant;  however,  if the  exercise  of the  Option is in  accordance  with
Section  220.3(e) of Regulation T  promulgated  by the Board of Governors of the
Federal  Reserve  System (a "cashless  exercise"),  the Option Price may be paid
directly by a registered  broker-dealer for the account of the Participant.  The
term "Fair Market  Value"  means,  as of any date,  the closing sales price of a
Share on such date as reported by (a) any national  securities exchange on which
the Shares are  actively  traded or (b) The Nasdaq Stock Market or, if no Shares
are traded on such exchange or system on such date,  then on the next  preceding
date on which any Shares were traded on such exchange or system.

     3.  The  Option  may  be  exercised  and  Shares  may be  purchased  by the
Participant  as the result of such  exercise  only  during the term set forth on
Exhibit A attached hereto;  provided,  however, that in no event shall the total
number of Shares  purchased  hereunder  pursuant  to the

                                       9
<PAGE>

exercise of the Option exceed the number set forth on Exhibit A attached hereto,
as the same may be adjusted in  accordance  with  Paragraph 8 hereof,  and in no
event shall the period for  exercising the Option exceed ten (10) years from the
date of the  grant of the  Option.  Exercise  of the  Option is  subject  to the
following additional terms and conditions:

               (a) In the event the Participant  ceases to be a Clinical Advisor
          other than as a result of the  Participant's  death, the Option may be
          exercised at any time after the date of such  cessation and before the
          earlier of (i) three (3) months  and (ii) the  expiration  date of the
          Option.

               (b) In the event the Participant  ceases to be a Clinical Advisor
          by reason of the  Participant's  death, the Option may be exercised at
          any time after the date of Participant's  death and before the earlier
          of (i) six (6) months after the date of  Participant's  death and (ii)
          the expiration date of the Option.

     4. In case of any exercise of the Option,  this  Agreement,  accompanied by
payment of the full  purchase  price for the  Shares  then  being  purchased  as
provided in Paragraph 2 above, shall be surrendered to the Company.  The Company
will thereupon cause to be issued and delivered to the  participant  (or, in the
event of a cashless exercise,  to the Participant's  broker-dealer),  as soon as
reasonably practicable, a certificate or certificates representing the Shares so
purchased  and fully paid for. In the event of a partial  exercise,  the Company
will  endorse  on  Exhibit B  attached  hereto the fact that the Option has been
partially exercised on such date, setting forth the extent of such exercise, and
return this Agreement to the Participant.

     5. The Option is personal to the  Participant  and may not in any manner or
respect be assigned or transferred otherwise than by will or the laws of descent
and distribution,  and is exercisable during the participant's  lifetime only by
the Participant.  To the extent the Option is not exercised,  the Shares covered
hereby shall be considered released to the Company.

     6. The  Option is in all  respects  subject  to and shall be  governed  and
determined  by any rules which might be adopted by the Board of Directors of the
Company with  respect  thereto to the same extent and with the same effect as if
set forth fully herein.

     7. This  Agreement  shall  terminate  no later than ten (10) years from the
date of grant of the Option.

     8. In the event of any change in corporate capitalization,  such as a stock
dividend  or  stock  split,  or a  corporate  transaction,  such as any  merger,
consolidation,  separation, including a spin-off, or other distribution of stock
or  property  of  the  Company,   any   reorganization   (whether  or  not  such
reorganization  comes within the  definition  of such term in Section 368 of the
Internal  Revenue Code) or any partial or complete  liquidation  of the Company,
such adjustment  shall be made in the number,  class and price of Shares subject
to the Option as may be determined to be appropriate  and equitable by the Board
of Directors  of the Company,  in its sole  discretion,  to prevent  dilution or
enlargement of rights;  provided,  however, that the number of Shares subject to
the Option shall always be a whole number.

                                       10
<PAGE>

     9. This Agreement shall be governed by and construed in accordance with the
laws  of  the  State  of  Delaware,   applied   without  giving  effect  to  any
conflict-of-law principles. Any invalidity or unenforceability of any particular
provision of this Agreement shall not affect the other  provisions  hereof,  and
this  Agreement  shall  be  construed  in all  respects  as if such  invalid  or
unenforceable provisions were omitted.

     10. This Agreement  shall be binding upon and shall inure to the benefit of
each of the  parties  hereto  and their  respective  executors,  administrators,
personal  representatives,   legal  representatives,  heirs  and  successors  in
interest.

     11. This Agreement may be executed in any number of  counterparts,  each of
which shall be  considered an original,  and such  counterparts  shall  together
constitute and be one and the same instrument.

     12. Upon demand by the Company,  the  Participant  agrees to deliver to the
Company at the time of any complete or partial exercise of this Option a written
representation  that the Shares  being  acquired  upon such  exercise  are being
acquired for  investment  and not for resale or with a view to the  distribution
thereof.

     13. The Company  shall have the power and the right to deduct or  withhold,
or require the  Participant  to remit to the Company,  an amount  sufficient  to
satisfy  federal,  state and  local  taxes  (including  the  Participant's  FICA
obligation)  required by law to be withheld  with  respect to any taxable  event
arising as a result of the grant or  exercise  of the  Option.  With  respect to
withholding required upon the exercise of the Option, the Participant may elect,
subject to the approval of the Board of Directors of the Company, to satisfy the
withholding  requirement,  in whole or in part,  by having the Company  withhold
Shares  having a Fair  Market  value  on the  date as of which  the tax is to be
determined  equal to the minimum  statutory  total tax which could be imposed on
the  transaction.  All such  elections  shall be  irrevocable,  made in writing,
signed by the  Participant,  and subject to any restrictions or limitations that
the  Board  of  Directors  of  the  Company,  in  its  sole  discretion,   deems
appropriate.

     IN WITNESS  WHEREOF,  the Company and the  Participant  have  executed  and
delivered this Agreement as of the day and year first written above.
