ITEM 4.   DESCRIPTION OF SECURITIES
          -------------------------

Not applicable.


ITEM 5.   INTERESTS OF NAMED EXPERTS AND COUNSEL
          --------------------------------------

Not applicable.


ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS
          -----------------------------------------

     (a)  Section 317 of the California General Corporation Law provides for the
          indemnification of officers and directors of the Company against
          expenses, judgments, fines and amounts paid in settlement under
          certain conditions and subject to certain limitations.

     (b)  Article VIII, Section 4 of the Bylaws of the Company provides that the
          Company shall have the power to indemnify any person who is or was a
          director, officer, employee or agent of the Company or any person who
          is or was serving at the request of the Company as a director,
          officer, employee or agent of another corporation, subject to certain
          limitations.  The rights to indemnity thereunder continue as to a
          person who has ceased to be director, officer, employee or agent and
          shall inure to the benefit of the heirs, executors and administrators
          of the person.  In addition,

                                      -1-
<PAGE>
 
          expenses incurred by a director, officer, employee or agent in
          defending a civil or criminal action, suit or proceeding by reason of
          the fact that he or she is or was a director, officer, employee or
          agent of the Company (or was serving at the Company's request as a
          director, officer, employee or agent of another corporation) may be
          paid by the Company in advance of the final disposition of such
          action, suit or proceeding upon receipt of an undertaking by or on
          behalf of such director or officer to repay such amount if it shall
          ultimately be determined that he or she is not entitled to be
          indemnified by the Company.

     (c)  Article Seventh of the Company's Articles of Incorporation provides
          that liability of the directors of the Company for monetary damages
          shall be eliminated to the fullest extent permissible under California
          law.  Article Eighth of the Company's Articles of Incorporation
          further provides that the Company is authorized to indemnify agents
          (as defined in Section 317 of the California General Corporation Law)
          in excess of the indemnification otherwise permitted by Section 317,
          subject to the limits set forth in Section 204 of the California
          General Corporation Law.

     (d)  Pursuant to authorization provided under the Articles of
          Incorporation, the Company has entered into indemnification agreements
          with its directors and officers.  Generally, the indemnification
          agreements attempt to provide the maximum protection permitted by
          California law as it may be amended from time to time.  Moreover, the
          indemnification agreements provide for certain additional
          indemnification.  the indemnification agreements provided for the
          Company to advance to the individual any and all reasonable expenses
          (including legal fees and expenses) incurred in investigating or
          defending an action, suit or proceeding.  In order to receive an
          advance of expenses, the individual must undertake to repay such
          advance upon a determination that he or she is not entitled to
          indemnification.  The Company's Bylaws contain a provision of similar
          effect relating to advancement of expenses to a director or officer,
          subject to an undertaking to repay if it is ultimately determined that
          indemnification is unavailable.

ITEM 9.   UNDERTAKINGS
          ------------

A.   The undersigned Registrant hereby undertakes: (1) to file, during any
     period in which offers or sales are being made, a post-effective amendment
     to this Registration Statement (i) to include any prospectus required

                                      -2-
<PAGE>
 
     by Section 10(a)(3) of the Securities Act of 1933, (ii) to reflect in the
     prospectus any facts or events arising after the effective date of this
     Registration Statement (or the most recent post-effective amendment
     thereof) which, individually or in the aggregate, represent a fundamental
     change in the information set forth in this Registration Statement, and
     (iii) to include any material information with respect to the plan of
     distribution not previously disclosed in this Registration Statement or any
     material change to such information in this Registration Statement;
     provided, however, (1) that clauses (1)(i) and (1)(ii) shall not apply if
     --------                                                                 
     the information required to be included in a post-effective amendment by
     those paragraphs is contained in periodic reports filed by the Registrant
     pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
     1934 that are incorporated by reference into this Registration Statement;
     (2) that for the purpose of determining any liability under the Securities
     Act of 1933 each such post-effective amendment shall be deemed to be a new
     registration statement relating to the securities offered therein and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof; and (3) that the Registrant shall remove from
     registration by means of a post-effective amendment any of the securities
     being registered which remain unsold upon termination of the Registrant's
     1995 Stock Option Plan.

B.   The undersigned registrant hereby undertakes that, for purposes of
     determining any liability under the Securities Act of 1933, each filing of
     the Registrants' annual report pursuant to Section 13(a) or 15(d) of the
     Securities Exchange Act of 1934 (and, where applicable, each filing of an
     employee benefit plan's annual report pursuant to Section 15(d) of the
     Securities Exchange Act of 1934) that is incorporated by reference in the
     Registration Statement shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.

C.   Insofar a indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to directors, officers or controlling persons of
     the Registrant pursuant to the indemnity provisions incorporated by
     reference in Item 6, or otherwise, the Registrant has been informed that in
     the opinion of the Securities and Exchange Commission such indemnification
     is against public policy as expressed in the 1933 Act and is, therefore,
     unenforceable.  In the event that a claim for indemnification against such
     liabilities (other than the payment by the Registrant of expenses incurred
     or paid by a director, officer or controlling person of the Registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer or controlling person in connection with the
     securities being registered, the Registrant will, unless in the opinion of
     its counsel the matter has been settled by controlling precedent, submit to
     a court of appropriate jurisdiction the question whether such
     indemnification by its is against public policy as expressed in the 1933
     Act and will be governed by the final adjudication of such issue.

                     -------------------------------------


                                  ARTICLE ONE
                              GENERAL PROVISIONS
                              ------------------


I.   PURPOSE OF THE PLAN

This 1995 Stock Option/Stock Issuance Plan (the "Plan") is intended to promote
the interests of Synbiotics Corporation, a California corporation, by providing
eligible persons with the opportunity to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation as an
incentive for them to remain in the service of the Corporation.

Capitalized terms not otherwise defined shall have the meanings assigned to such
terms in the attached Appendix.


II.  STRUCTURE OF THE PLAN

     A.   The Plan shall be divided into three separate equity programs:

          (i)  the Discretionary Option Grant Program under which eligible
               persons may, at the discretion of the Plan Administrator, be
               granted options to purchase shares of common stock of the
               Corporation,

          (ii) the Stock Issuance Program under which eligible persons may, at
               the discretion of the Plan Administrator, be issued shares of
               common stock of the Corporation directly, either through the
               immediate purchase of such shares or as a bonus for services
               rendered the Corporation (or any Parent or Subsidiary), and

          (iii)the Automatic Option Grant Program under which non-employee
               directors shall automatically receive option grants at periodic
               intervals to purchase shares of common stock of the Corporation.

     B.   The provisions of Articles One and Five shall apply to all equity
          programs under the Plan and shall accordingly govern the interests of
          all persons under the Plan.


III. ADMINISTRATION OF THE PLAN

     A.   This Plan shall be administered by the Board or by a committee
          ("Committee") consisting of two (2) or more Board members who assume
          full responsibility for the administration of the Plan (the "Plan
          Administrator").  Members of any Committee shall serve for such period
          of time as the Board may determine and shall be subject to removal by
          the Board at any time.

                                      -1-
<PAGE>
 
     B.   The Plan Administrator shall have full power and authority (subject to
          the express provisions of the Plan) to establish such rules and
          regulations as it may deem appropriate for the proper administration
          of the Plan and to make such determinations under, and issue such
          interpretations of, the Plan and any outstanding option grants or
          stock issuances as it may deem necessary or advisable.  Decisions of
          the Plan Administrator shall be final and binding on all parties who
          have an interest in the Plan or any outstanding option or stock
          issuance.

     C.   Notwithstanding the above, the administration of the Automatic Option
          Grant Program under Article Three shall be self executing in
          accordance with the terms and conditions thereof and the Plan
          Administrator shall not exercise any discretionary functions in
          respect to matters governed by Article Three.

     D.   The Plan Administrator shall, within the scope of its administrative
          jurisdiction under the Plan, have full authority to determine, (i)
          with respect to the option grants under the Discretionary Option Grant
          Program, which eligible persons are to receive option grants, the time
          or times when such option grants are to be made, the number of shares
          to be covered by each such grant, the status of the granted option as
          either an Incentive Option or a Non-Statutory Option, the time or
          times at which each option is to become exercisable, the vesting
          schedule (if any) applicable to the option shares and the maximum term
          for which the option is to remain outstanding and (ii) with respect to
          stock issuances under the Stock Issuance Program, which eligible
          persons are to receive stock issuances, the time or times when such
          issuances are to be made, the number of shares to be issued to each
          Participant, the vesting schedule (if any) applicable to the issued
          shares and the consideration to be paid by the Participant for such
          shares.

     E.   The Plan Administrator shall have the absolute discretion either to
          grant options in accordance with the Discretionary Option Grant
          Program or to effect stock issuances in accordance with the Stock
          Issuance Program.


IV.  OPTION GRANTS AND STOCK ISSUANCES

     A.   Subject to Section V.B below, the persons eligible to receive stock
          issuances under the Stock Issuance Program ("Participant") and/or
          option grants pursuant to the Discretionary Option Grant Program
          ("Optionee") are as follows:

          (i)  officers and other employees of the Corporation (or its parent or
               subsidiary corporations) who render services which contribute to
               the management, growth and financial success of the Corporation
               (or its parent or subsidiary corporations);

          (ii) those consultants or other independent contractors who provide
               valuable services to the Corporation (or its parent or subsidiary
               corporations);

          provided that, notwithstanding any other provision of this Plan, no
          option grants under the Discretionary Option Grant Program or stock
          issuances under the Stock Issuance Program shall be made to any
          director hereunder unless, at the time of such option or issuance, the
          Plan Administrator is a Committee composed entirely of non-employee
          Board members none of whom have received an option grant or stock
          issuance under this Plan or any other stock plan of the Corporation
          (or any parent or subsidiary corporation) other than under the
          Automatic Option Grant Program during the one year prior to service on
          the Committee or during such service.

     B.   The individuals eligible to receive option grants under the Automatic
          Option Grant Program shall

                                      -2-
<PAGE>
 
          be those individuals who serve as non-employee Board members during
          the term of the Plan.


V.   STOCK SUBJECT TO THE PLAN

     A.   The stock issuable under the Plan shall be shares of authorized but
          unissued or reacquired common stock of the Corporation ("Common
          Stock"), including shares repurchased by the Corporation on the open
          market.  The maximum number of shares of Common Stock which may be
          issued over the term of the Plan shall not exceed 1,300,000 shares.
          Such authorized share reserve is comprised of (i) the number of shares
          available for issuance under the Predecessor Plan as last approved by
          the Corporation's stockholders prior to such date, including the
          shares subject to the outstanding options incorporated into the Plan
          and any other shares which would have been available for future option
          grants under the Predecessor Plan, plus (ii) an additional increase of
          282,055 shares authorized by the Board under the Plan, subject to
          stockholder approval.

     B.   No one person participating in the Plan may receive options and direct
          stock issuances for more than 800,000 shares of Common Stock in the
          aggregate over the term of the Plan.

     C.   Shares of Common Stock subject to outstanding options shall be
          available for subsequent issuance under the Plan to the extent (i) the
          options  (including any options incorporated from the Predecessor
          Plan) expire or terminate for any reason prior to exercise in full or
          (ii) the options are cancelled in accordance with the cancellation-
          regrant provisions of Article Two.  All shares issued under the Plan
          (including shares issued upon exercise of options incorporated from
          the Predecessor Plan), whether or not those shares are subsequently
          repurchased by the Corporation pursuant to its repurchase rights under
          the Plan, shall reduce on a share-for-share basis the number of shares
          of Common Stock available for subsequent issuance under the Plan.  In
          addition, should the exercise price of an option under the Plan
          (including any option incorporated from the Predecessor Plan) be paid
          with shares of Common Stock or should shares of Common Stock otherwise
          issuable under the Plan be withheld by the Corporation in satisfaction
          of the withholding taxes incurred in connection with the exercise of
          an option or the vesting of a stock issuance under the Plan, then the
          number of shares of Common Stock available for issuance under the Plan
          shall be reduced by the gross number of shares for which the option is
          exercised or which vest under the stock issuance, and not by the net
          number of shares of Common Stock issued to the holder of such option
          or stock issuance.

     D.   Should any change be made to the Common Stock by reason of any stock
          split, stock dividend, recapitalization, combination of shares,
          exchange of shares or other change affecting the outstanding Common
          Stock as a class without the Corporation's receipt of consideration,
          appropriate adjustments shall be made to (i) the maximum number and/or
          class of securities issuable under the Plan, (ii) the maximum number
          and/or class of securities for which the share reserve is to increase
          automatically each year, (iii) the number and/or class of securities
          for which any one person may be granted options and direct stock
          issuances over the term of the Plan, (iv) the number and/or class of
          securities for which automatic option grants are to be subsequently
          made under the Automatic Option Grant Program and (v) the number
          and/or class of securities and the exercise price per share in effect
          under each outstanding option (including any option incorporated from
          the Predecessor Plan) in order to prevent the dilution or enlargement
          of benefits thereunder.  The adjustments determined by the Plan
          Administrator shall be final, binding and conclusive.

                      ----------------------------------


I.   OPTION TERMS

Each option shall be evidenced by one or more documents in the form approved by
the Plan Administrator; provided, however, that each such document shall comply
                        --------                                               
with the terms specified below.  Each document evidencing an Incentive Option
shall, in addition, be subject to the provisions of the Plan applicable to such
options.

     A.   Exercise Price.
          -------------- 

          1.   The exercise price per share shall be fixed by the Plan
               Administrator but shall not be less than eighty-five percent
               (85%) of the Fair Market Value per share of  Common Stock on the
               option grant date.

          2.   The exercise price shall become immediately due upon exercise of
               the option and shall, subject to the provisions of Section I of
               Article Five and the documents evidencing the option, be payable
               in one or more of the forms specified below:

               (i)  cash or check made payable to the Corporation,

               (ii) shares of Common Stock held for the requisite period
                    necessary to avoid a charge to the Corporation's earnings
                    for financial reporting purposes and valued at Fair Market
                    Value on the exercise date, or

               (iii)to the extent the option is exercised for vested shares,
                    through a special sale and remittance procedure pursuant to
                    which the Optionee shall concurrently provide irrevocable
                    written instructions to (a) a Corporation-designated
                    brokerage firm to effect the immediate sale of the purchased
                    shares and remit to the Corporation, out of the sale
                    proceeds available on the settlement date, sufficient funds
                    to cover the aggregate exercise price payable for the
                    purchased shares plus all applicable Federal, state and
                    local income and employment taxes required to be withheld by
                    the Corporation by reason of such exercise and (b) the
                    Corporation to deliver the certificates for the purchased
                    shares directly to such brokerage firm in order to complete
                    the sale transaction.

               Except to the extent such sale and remittance procedure is
               utilized, payment of the exercise price for the purchased shares
               must be made on the exercise date.

     B.   Exercise and Term of Options.  Each option shall be exercisable at
          ----------------------------                                      
          such time or times, during such period and for such number of shares
          as shall be determined by the Plan Administrator and set forth in the
          documents evidencing the option.  However, no option shall have a term
          in excess of ten (10) years measured from the option grant date.

     C.   Effect of Termination of Service.
          -------------------------------- 

          1.   The following provisions shall govern the exercise of any options
               held by the Optionee at the time of cessation of Service or
               death:

                                      -4-
<PAGE>
 
               (i)  Any option outstanding at the time of the Optionee's
                    cessation of Service for any reason shall remain exercisable
                    for such period of time thereafter as shall be determined by
                    the Plan Administrator and set forth in the documents
                    evidencing the option, but no such option shall be
                    exercisable after the expiration of the option term.

               (ii) Any option exercisable in whole or in part by the Optionee
                    at the time of death may be subsequently exercised by the
                    personal representative of the Optionee's estate or by the
                    person or persons to whom the option is transferred pursuant
                    to the Optionee's will or in accordance with the laws of
                    descent and distribution.

               (iii)During the applicable post-Service exercise period, the
                    option may not be exercised in the aggregate for more than
                    the number of vested shares for which the option is
                    exercisable on the date of the Optionee's cessation of
                    Service.  Upon the expiration of the applicable exercise
                    period or (if earlier) upon the expiration of the option
                    term, the option shall terminate and cease to be outstanding
                    for any vested shares for which the option has not been
                    exercised.  However, the option shall, immediately upon the
                    Optionee's cessation of Service, terminate and cease to be
                    outstanding to the extent it is not exercisable for vested
                    shares on the date of such cessation of Service.

               (iv) In the event of a Corporate Transaction,the provisions of
                    Section III of this Article Two shall govern the period for
                    which the outstanding options are to remain exercisable
                    following the Optionee's cessation of Service and shall
                    supersede any provisions to the contrary in this section.

          2.   The Plan Administrator shall have the discretion, exercisable
               either at the time an option is granted or at any time while the
               option remains outstanding, to:

               (i)  extend the period of time for which the option is to remain
                    exercisable following the Optionee's cessation of Service
                    from the period otherwise in effect for that option to such
                    greater period of time as the Plan Administrator shall deem
                    appropriate, but in no event beyond the expiration of the
                    option term, and/or

               (ii) permit the option to be exercised, during the applicable
                    post-Service exercise period, not only with respect to the
                    number of vested shares of Common Stock for which such
                    option is exercisable at the time of the Optionee's
                    cessation of Service but also with respect to one or more
                    additional installments in which the Optionee would have
                    vested under the option had the Optionee continued in
                    Service.

     D.   Stockholder Rights.  The holder of an option shall have no stockholder
          ------------------                                                    
          rights with respect to the shares subject to the option until such
          person shall have exercised the option, paid the exercise price and
          become a holder of record of the purchased shares.

     E.   Repurchase Rights.  The Plan Administrator shall have the discretion
          -----------------                                                   
          to grant options which are exercisable for unvested shares of Common
          Stock.  Should the Optionee cease Service while holding such unvested
          shares, the Corporation shall have the right to repurchase, at the
          exercise price paid per share, any or all of those unvested shares.
          The terms upon which such repurchase right shall be exercisable
          (including the period and procedure for exercise and the appropriate
          vesting schedule for the purchased shares) shall be established by the
          Plan Administrator and set

                                      -5-
<PAGE>
 
          forth in the document evidencing such repurchase right.

     F.   Limited Transferability of Options.  During the lifetime of the
          ----------------------------------                             
          Optionee, the option shall be exercisable only by the Optionee and
          shall not be assignable or transferable other than by will or by the
          laws of descent and distribution following the Optionee's death.
          However, a Non-Statutory Option may be assigned in accordance with the
          terms of a Qualified Domestic Relations Order within the meaning of
          Internal Revenue Code Section 414(p).  The assigned option may only be
          exercised by the person or persons who acquire a proprietary interest
          in the option pursuant to such Qualified Domestic Relations Order.
          The terms applicable to the assigned option (or portion thereof) shall
          be the same as those in effect for the option immediately prior to
          such assignment and shall be set forth in such documents issued to the
          assignee as the Plan Administrator may deem appropriate


II.  INCENTIVE OPTIONS

The terms specified below shall be applicable to all Incentive Options.  Except
as modified by the provisions of this Section II, all the provisions of Articles
One, Two and Five shall be applicable to Incentive Options. Options which are
specifically designated as Non-Statutory Options when issued under the Plan
shall not be subject to the terms of this Section II.
      ---                                            

     A.   Eligibility.  Incentive Options may only be granted to Employees.
          -----------                                                      

     B.   Exercise Price.  The exercise price per share shall not be less than
          --------------                                                      
          one hundred percent (100%) of the Fair Market Value per share of
          Common Stock on the option grant date.

     C.   Dollar Limitation.  The aggregate Fair Market Value of the shares of
          -----------------                                                   
          Common Stock (determined as of the respective date or dates of grant)
          for which one or more options granted to any Employee under the Plan
          (or any other option plan of the Corporation or any Parent or
          Subsidiary) may for the first time become exercisable as Incentive
          Options during any one (1) calendar year shall not exceed the sum of
          One Hundred Thousand Dollars ($100,000).  To the extent the Employee
          holds two (2) or more such options which become exercisable for the
          first time in the same calendar year, the foregoing limitation on the
          exercisability of such options as Incentive Options shall be applied
          on the basis of the order in which such options are granted.

     D.   10% Stockholder.  If any Employee to whom an Incentive Option is
          ---------------                                                 
          granted is a 10% stockholder (within the meaning of Internal Revenue
          Code Section 424(d)), then the exercise price per share shall not be
          less than one hundred ten percent (110%) of the Fair Market Value per
          share of Common Stock on the option grant date, and the option term
          shall not exceed five (5) years measured from the option grant date.


III. CORPORATE TRANSACTION

     A.   In the event of any Corporate Transaction, each outstanding option
          shall automatically accelerate so that each such option shall,
          immediately prior to the effective date of the Corporate Transaction,
          become fully exercisable for all of the shares of Common Stock at the
          time subject to such option and may be exercised for any or all of
          those shares as fully-vested shares of Common Stock.  However, an
          outstanding option shall NOT so accelerate if and to the extent:  (i)
          such option is, in connection with the Corporate Transaction, either
          to be assumed by the successor corporation (or parent thereof) or to
          be replaced with a comparable option to purchase shares of the capital
          stock

                                      -6-
<PAGE>
 
          of the successor corporation (or parent thereof), (ii) such option is
          to be replaced with a cash incentive program of the successor
          corporation which preserves the spread existing on the unvested option
          shares at the time of the Corporate Transaction and provides for
          subsequent payout in accordance with the same vesting schedule
          applicable to such option or (iii) the acceleration of such option is
          subject to other limitations imposed by the Plan Administrator at the
          time of the option grant.  The determination of option comparability
          under clause (i) above shall be made by the Plan Administrator, and
          its determination shall be final, binding and conclusive.

     B.   All outstanding repurchase rights shall also terminate automatically,
          and the shares of Common Stock subject to those terminated rights
          shall immediately vest in full, in the event of any Corporate
          Transaction, except to the extent: (i) those repurchase rights are to
          be assigned to the successor corporation (or parent thereof) in
          connection with such Corporate Transaction or (ii) such accelerated
          vesting is precluded by other limitations imposed by the Plan
          Administrator at the time the repurchase right is issued.

     C.   Immediately following the consummation of the Corporate Transaction,
          all outstanding options shall terminate and cease to be outstanding,
          except to the extent assumed by the successor corporation (or parent
          thereof).

     D.   Each option which is assumed in connection with a Corporate
          Transaction shall be appropriately adjusted, immediately after such
          Corporate Transaction, to apply to the number and class of securities
          which would have been issuable to the Optionee in consummation of such
          Corporate Transaction had the option been exercised immediately prior
          to such Corporate Transaction.  Appropriate adjustments shall also be
          made to (i) the number and class of securities available for issuance
          under the Plan on both an aggregate and per Optionee basis following
          the consummation of such Corporate Transaction and (ii) the exercise
          price payable per share under each outstanding option, provided the
                                                                 --------    
          aggregate exercise price payable for such securities shall remain the
          same.

     E.   Any options which are assumed or replaced in the Corporate Transaction
          and do not otherwise accelerate at that time, shall automatically
          accelerate (and any of the Corporation's outstanding repurchase rights
          which do not otherwise terminate at the time of the Corporate
          Transaction shall automatically terminate and the shares of Common
          Stock subject to those terminated rights shall immediately vest in
          full) in the event the Optionee's Service should subsequently
          terminate by reason of an Involuntary Termination within eighteen (18)
          months following the effective date of such Corporate Transaction.
          Any options so accelerated shall remain exercisable for fully-vested
          shares until the earlier of (i) the expiration of the option term or
                           -------                                            
          (ii) the expiration of the one (1)-year period measured from the
          effective date of the Involuntary Termination.

     F.   The portion of any Incentive Option accelerated in connection with a
          Corporate Transaction or Change in Control shall remain exercisable as
          an Incentive Option only to the extent the applicable One Hundred
          Thousand Dollar limitation is not exceeded.  To the extent such dollar
          limitation is exceeded, the accelerated portion of such option shall
          be exercisable as a Non-Statutory Option under the Federal tax laws.

     G.   The grant of options under the Discretionary Option Grant Program
          shall in no way affect the right of the Corporation to adjust,
          reclassify, reorganize or otherwise change its capital or business
          structure or to merge, consolidate, dissolve, liquidate or sell or
          transfer all or any part of its business or assets.

IV.  CANCELLATION AND REGRANT OF OPTIONS

The Plan Administrator shall have the authority to effect, at any time and from
time to time, with the consent of the affected option holders, the cancellation
of any or all outstanding options under the Discretionary Option Grant Program
(including outstanding options incorporated from the Predecessor Plan) and to
grant in substitution new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                            STOCK ISSUANCE PROGRAM
                            ----------------------


I.   STOCK ISSUANCE TERMS

Shares of Common Stock may be issued under the Stock Issuance Program through
direct and immediate issuances without any intervening option grants.  Each such
stock issuance shall be evidenced by a Stock Issuance Agreement which complies
with the terms specified below.

     A.   Purchase Price
          --------------

          1.   The purchase price per share shall be fixed by the Plan
               Administrator, but shall not be less than eighty-five percent
               (85%) of the Fair Market Value per share of Common Stock on the
               stock issuance date.

          2.   Subject to the provisions of Section I of Article Five, shares of
               Common Stock may be issued under the Stock Issuance Program for
               one or both of the following items of consideration which the
               Plan Administrator may deem appropriate in each individual
               instance:

               (i)  cash or check made payable to the Corporation, or

               (ii) past services rendered to the Corporation (or any Parent or
                    Subsidiary).

     B.   Vesting Provisions
          ------------------

          1.   Shares of Common Stock issued under the Stock Issuance Program
               may, in the discretion of the Plan Administrator, be fully and
               immediately vested upon issuance or may vest in one or more
               installments over the Participant's period of Service or upon
               attainment of specified performance objectives.  The elements of
               the vesting schedule applicable to any unvested shares of Common
               Stock issued under the Stock Issuance Program, namely:

               (i)  the Service period to be completed by the Participant or the
                    performance objectives to be attained,

               (ii) the number of installments in which the shares are to vest,

               (iii)the interval or intervals (if any) which are to lapse
                    between installments, and

               (iv) the effect which death, Permanent Disability or other event
                    designated by the

                                      -8-
<PAGE>
 
                    Plan Administrator is to have upon the vesting schedule,

               shall be determined by the Plan Administrator and incorporated
               into the stock issuance agreement.

          2.   Any new, substituted or additional securities or other property
               (including money paid other than as a regular cash dividend)
               which the Participant may have the right to receive with respect
               to the Participant's unvested shares of Common Stock by reason of
               any stock dividend, stock split, recapitalization, combination of
               shares, exchange of shares or other change affecting the
               outstanding Common Stock as a class without the Corporation's
               receipt of consideration shall be issued subject to (i) the same
               vesting requirements applicable to the Participant's unvested
               shares of Common Stock and (ii) such escrow arrangements as the
               Plan Administrator shall deem appropriate.

          3.   The Participant shall have full stockholder rights with respect
               to any shares of Common Stock issued to the Participant under the
               Stock Issuance Program, whether or not the Participant's interest
               in those shares is vested.  Accordingly, the Participant shall
               have the right to vote such shares and to receive any regular
               cash dividends paid on such shares.

          4.   Should the Participant cease to remain in Service while holding
               one or more unvested shares of Common Stock issued under the
               Stock Issuance Program or should the performance objectives not
               be attained with respect to one or more such unvested shares of
               Common Stock, then those shares shall be immediately surrendered
               to the Corporation for cancellation, and the Participant shall
               have no further stockholder rights with respect to those shares.
               To the extent the surrendered shares were previously issued to
               the Participant for consideration paid in cash or cash equivalent
               (including the Participant's purchase-money indebtedness), the
               Corporation shall repay to the Participant the cash consideration
               paid for the surrendered shares and shall cancel the unpaid
               principal balance of any outstanding purchase-money note of the
               Participant attributable to such surrendered shares.

          5.   The Plan Administrator may in its discretion waive the surrender
               and cancellation of one or more unvested shares of Common Stock
               (or other assets attributable thereto) which would otherwise
               occur upon the non-completion of the vesting schedule applicable
               to such shares.  Such waiver shall result in the immediate
               vesting of the Participant's interest in the shares of Common
               Stock as to which the waiver applies.  Such waiver may be
               effected at any time, whether before or after the Participant's
               cessation of Service or the attainment or non-attainment of the
               applicable performance objectives.


II.  CORPORATE TRANSACTION

     A.   All of the outstanding repurchase rights under the Stock Issuance
          Program shall terminate automatically, and all the shares of Common
          Stock subject to those terminated rights shall immediately vest in
          full, in the event of any Corporate Transaction, except to the extent
          (i) those repurchase rights are assigned to the successor corporation
          (or parent thereof) in connection with such Corporate Transaction or
          (ii) such accelerated vesting is precluded by other limitations
          imposed in the stock issuance agreement.

     B.   Any repurchase rights that are assigned in the Corporate Transaction
          shall automatically terminate, and all the shares of Common Stock
          subject to those terminated rights shall immediately vest in

                                      -9-
<PAGE>
 
          full, in the event the Optionee's Service should subsequently
          terminate by reason of an Involuntary Termination within eighteen (18)
          months following the effective date of such Corporate Transaction.


III. SHARE ESCROW/LEGENDS

Unvested shares may, in the Plan Administrator's discretion, be held in escrow
by the Corporation until the Participant's interest in such shares vests or may
be issued directly to the Participant with restrictive legends on the
certificates evidencing those unvested shares.

                        AUTOMATIC OPTION GRANT PROGRAM
                        ------------------------------


I.   OPTION TERMS

     A.   Grant Dates.  Option grants shall be made on the dates specified
          -----------                                                     
          below:

          1.   Each non-employee director who is who is first elected or
               appointed as a non-employee Board member after the effective date
               of the Plan shall automatically be granted, on such initial
               election or appointment, a Non-Statutory Option to purchase 7,000
               shares of Common Stock.

          2.   On the date of each Annual Stockholders Meeting, beginning with
               the 1995 Annual Meeting, each individual who is to continue to
               serve as a non-employee director after such meeting, shall
               automatically be granted, whether or not such individual is
               standing for re-election as a Board member at that Annual
               Meeting, a Non-Statutory Option to purchase an additional 7,000
               shares of Common Stock, provided such individual has served as a
               non-employee Board member for at least six (6) months prior to
               the date of such Annual Meeting.  There shall be no limit on the
               number of such 7,000-share option grants any one non-employee
               director may receive over his or her period of Board service.

     B.   Exercise Price.
          -------------- 

          1.   The exercise price per share shall be equal to one hundred
               percent (100%) of the Fair Market Value per share of Common Stock
               on the option grant date.

          2.   The exercise price shall be payable in one or more of the
               alternative forms authorized under the Discretionary Option Grant
               Program.  Except to the extent the sale and remittance procedure
               specified thereunder is utilized, payment of the exercise price
               for the purchased shares must be made on the exercise date.

     C.   Option Term.  Each option shall have a term of ten (10) years measured
          -----------                                                           
          from the option grant date.

     D.   Exercise and Vesting of Options.  Each option shall be immediately
          -------------------------------                                   
          exercisable for any or all of the option shares.  However, any shares
          purchased under the option shall be subject to repurchase by the
          Corporation, at the exercise price paid per share, upon the Optionee's
          cessation of Board

                                      -10-
<PAGE>
 
          service prior to vesting in those shares.  Each grant shall vest, and
          the Corporation's repurchase right shall lapse, in a series of four
          (4) equal and successive quarterly installments over the Optionee's
          period of continued service as a Board member, with the first such
          installment to vest upon the Optionee's completion of three (3) months
          of Board service measured from the option grant date.

     E.   Effect of Termination of Board Service.  The following provisions
          --------------------------------------                           
          shall govern the exercise of any options held by the Optionee at the
          time the Optionee ceases to serve as a Board member:

          (i)  The Optionee (or, in the event of Optionee's death, the personal
               representative of the Optionee's estate or the person or persons
               to whom the option is transferred pursuant to the Optionee's will
               or in accordance with the laws of descent and distribution) shall
               have the balance of the option term in which to exercise each
               such option.

          (ii) Following cessation of service on the Board for other than death
               or disability, the option may not be exercised in the aggregate
               for more than the number of vested shares of Common Stock for
               which the option was exercisable at the time of the Optionee's
               cessation of Board service.

          (iii)Should the Optionee cease to serve as a Board member by reason
               of death or Permanent Disability, then all shares at the time
               subject to the option shall immediately vest so that such option
               may be exercised for all or any portion of such shares as fully-
               vested shares of Common Stock.

          (iv) Upon expiration of the option term, the option shall terminate
               and cease to be outstanding for any vested shares for which the
               option has not been exercised.  However, the option shall,
               immediately upon the Optionee's cessation of Board service,
               terminate and cease to be outstanding to the extent it is not
               exercisable for vested shares on the date of such cessation of
               Board service.


II.  CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

     A.   In the event of any Corporate Transaction, the shares of Common Stock
          at the time subject to each outstanding option but not otherwise
          vested shall automatically vest in full so that each such option
          shall, immediately prior to the effective date of the Corporate
          Transaction, become fully exercisable for all of the shares of Common
          Stock at the time subject to such option and may be exercised for all
          or any portion of such shares as fully-vested shares of Common Stock.
          Immediately following the consummation of the Corporate Transaction,
          each automatic option grant shall terminate and cease to be
          outstanding, except to the extent assumed by the successor corporation
          (or parent thereof).

     B.   In connection with any Change in Control, the shares of Common Stock
          at the time subject to each outstanding option but not otherwise
          vested shall automatically vest in full so that each such option
          shall, immediately prior to the effective date of the Change in
          Control, become fully exercisable for all of the shares of Common
          Stock at the time subject to such option and may be exercised for all
          or any portion of such shares as fully-vested shares of Common Stock.
          Each such option shall remain exercisable for such fully-vested option
          shares until the expiration or sooner termination of the option term
          or the surrender of the option in connection with a Hostile Take-Over.

     C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall have a
          thirty (30)-day period in

<PAGE>
 
          which to surrender to the Corporation each automatic option held by
          him or her for a period of at least six (6) months.  The Optionee
          shall in return be entitled to a cash distribution from the
          Corporation in an amount equal to the excess of (i) the Take-Over
          Price of the shares of Common Stock at the time subject to the
          surrendered option (whether or not the Optionee is otherwise at the
          time vested in those shares) over (ii) the aggregate exercise price
          payable for such shares.  Such cash distribution shall be paid within
          five (5) days following the surrender of the option to the
          Corporation.  No approval or consent of the Board shall be required in
          connection with such option surrender and cash distribution.

D.   The grant of options under the Automatic Option Grant Program shall in no
     way affect the right of the Corporation to adjust, reclassify, reorganize
     or otherwise change its capital or business structure or to merge,
     consolidate, dissolve, liquidate or sell or transfer all or any part of its
     business or assets.


III. AMENDMENT OF THE AUTOMATIC OPTION GRANT PROGRAM

with applicable Federal income tax laws and regulations.


IV.  REMAINING TERMS

Program shall be the same as the terms in effect for option grants made under
the Discretionary Option Grant Program.

                                 MISCELLANEOUS
                                 -------------


I.   ACCELERATION

     A.   The Plan Administrator shall have the discretion, exercisable either
          at the time an option is granted under the Discretionary Stock Option
          Program, at the time that stock is issued under the Stock Issuance
          Program or at any time while the option or stock remains outstanding,
          to provide for the acceleration of one or more outstanding options and
          the termination of repurchase rights on one or more outstanding shares
          upon the occurrence of such events as the Plan Administrator may
          determine, including upon a Corporate Transaction regardless or
          whether or not such options are to be assumed or replaced or the
          repurchase rights are to be assigned in the Corporate Transaction.

     B.   The Plan Administrator shall not have the discretion to provide for
          the acceleration of any options granted under the Automatic Option
          Grant Program.
 

II.  FINANCING

     A.   The Plan Administrator may permit any Optionee or Participant to pay
          the option exercise price under the Discretionary Option Grant Program
          or the purchase price for shares issued under the Stock Issuance
          Program by delivering a promissory note payable in one or more
          installments.   The

                                      -12-
<PAGE>
 
          terms of any such promissory note (including the interest rate and the
          terms of repayment) shall be established by the Plan Administrator in
          its sole discretion.  Promissory notes may be authorized with or
          without security or collateral.  In all events, the maximum credit
          available to the Optionee or Participant may not exceed the sum of (i)
          the aggregate option exercise price or purchase price payable for the
          purchased shares plus (ii) any Federal, state and local income and
          employment tax liability incurred by the Optionee or the Participant
          in connection with the option exercise or share purchase.

     B.   The Plan Administrator may, in its discretion, determine that one or
          more such promissory notes shall be subject to forgiveness by the
          Corporation in whole or in part upon such terms as the Plan
          Administrator may deem appropriate.


III. TAX WITHHOLDING

     A.   The Corporation's obligation to deliver shares of Common Stock upon
          the exercise of options or upon the issuance or vesting of such shares
          under the Plan shall be subject to the satisfaction of all applicable
          Federal, state and local income and employment tax withholding
          requirements.

     B.   The Plan Administrator may, in its discretion, provide any or all
          holders of Non-Statutory Options or unvested shares of Common Stock
          under the Plan (other than the options granted or the shares issued
          under the Automatic Option Grant Program) with the right to use shares
          of Common Stock in satisfaction of all or part of the federal, state
          and local income or employment taxes incurred by such holders in
          connection with the exercise of their options or the vesting of their
          shares.  Such right may be provided to any such holder in either or
          both of the following formats:

          (i)  Stock Withholding:  The election to have the Corporation
               -----------------                                       
               withhold, from the shares of Common Stock otherwise issuable upon
               the exercise of such Non-Statutory Option or the vesting of such
               shares, a portion of those shares with an aggregate Fair Market
               Value equal to the percentage of such taxes (not to exceed one
               hundred percent (100%)) designated by the holder.

          (ii) Stock Delivery:  The election to deliver to the Corporation, at
               --------------                                                 
               the time the Non-Statutory Option is exercised or the shares
               vest, one or more shares of Common Stock previously acquired by
               such holder (other than in connection with the option exercise or
               share vesting triggering the taxes) with an aggregate Fair Market
               Value equal to the percentage of such taxes (not to exceed one
               hundred percent (100%)) designated by the holder.


IV.  EFFECTIVE DATE AND TERM OF THE PLAN

     A.   The Plan shall become effective on the date the Plan is adopted by the
          Board, and options may be granted under the Discretionary Option Grant
          Program from and after the effective date.  However, no options
          granted under the Plan may be exercised, and no shares shall be issued
          under the Plan, until the Plan is approved by the Corporation's
          stockholders.  If such stockholder approval is not obtained within
          twelve (12) months after such effective date, then all options
          previously granted under this Plan shall terminate and cease to be
          outstanding, and no further options shall be granted and no shares
          shall be issued under the Plan.

     B.   The Plan shall serve as the successor to the Predecessor Plan, and no
          further option grants shall be made under the Predecessor Plan after
          the effective date of the Plan.  All options outstanding

                                      -13-
<PAGE>
 
          under the Predecessor Plan as of such date shall, immediately upon
          approval of the Plan by the Corporations's stockholders, be
          incorporated into the Plan and treated as outstanding options under
          the Plan.  However, each outstanding option so incorporated shall
          continue to be governed solely by the terms of the documents
          evidencing such option.  No provision of the Plan shall be deemed to
          adversely affect or otherwise diminish the rights or obligations of
          the holders of such incorporated options with respect to their
          acquisition of shares of Common Stock which may exist under the terms
          of the Predecessor Plan under which such incorporated option was
          issued.  Subject to the rights of the optionee under the incorporated
          option documents and Predecessor Plan, the discretion delegated to the
          Plan Administrator hereunder may be exercised with respect to
          incorporated options to the same extent as it is exercisable with
          respect to options originally granted under this Plan.

     C.   The option/vesting acceleration provisions of Article Two relating to
          Corporate Transactions and Changes in Control may, in the Plan
          Administrator's discretion, be extended to one or more options
          incorporated from the Predecessor Plan which do not otherwise provide
          for such acceleration.

     D.   The Plan shall terminate upon the earliest of (i) April 27, 2005, (ii)
                                            --------                            
          the date on which all shares available for issuance under the Plan
          shall have been issued pursuant to the exercise of the options or the
          issuance of shares (whether vested or unvested) under the Plan or
          (iii) the termination of all outstanding options in connection with a
          Corporate Transaction.  Upon such Plan termination, all options and
          unvested stock issuances outstanding on such date shall thereafter
          continue to have force and effect in accordance with the provisions of
          the documents evidencing such options or issuances.


V.   AMENDMENT OF THE PLAN

     A.   The Board shall have complete and exclusive power and authority to
          amend or modify the Plan in any or all respects.  However, (i) no such
          amendment or modification shall adversely affect the rights and
          obligations with respect to options or unvested stock issuances at the
          time outstanding under the Plan unless the Optionee or the Participant
          consents to such amendment or modification, and (ii) any amendment
          made to the Automatic Option Grant Program (or any options outstanding
          thereunder) shall be in compliance with the limitations of that
          program.  In addition, the Board shall not, without the approval of
          the Corporation's stockholders, (i) materially increase the maximum
          number of shares issuable under the Plan, the number of shares for
          which options may be granted under the Automatic Option Grant Program
          or the maximum number of shares for which any one person may be
          granted options and direct stock issuances in the aggregate over the
          term of the Plan, except for permissible adjustments in the event of
          certain changes in the Corporation's capitalization, (ii) materially
          modify the eligibility requirements for Plan participation or (iii)
          materially increase the benefits accruing to Plan participants.

     B.   Options to purchase shares of Common Stock may be granted under the
          Discretionary Option Grant Program and shares of Common Stock may be
          issued under the Stock Issuance Program that are in each instance in
          excess of the number of shares then available for issuance under the
          Plan, provided any excess shares actually issued under those programs
          are held in escrow until there is obtained stockholder approval of an
          amendment sufficiently increasing the number of shares of Common Stock
          available for issuance under the Plan.  If such stockholder approval
          is not obtained within twelve (12) months after the date the first
          such excess issuances are made, then (i) any unexercised options
          granted on the basis of such excess shares shall terminate and cease
          to be outstanding and (ii) the Corporation shall promptly refund to
          the Optionees and the Participants the exercise or purchase price paid
          for any excess shares issued under the Plan and held in escrow,

                                      -14-
<PAGE>
 
          together with interest (at the applicable Short Term Federal Rate) for
          the period the shares were held in escrow, and such shares shall
          thereupon be automatically cancelled and cease to be outstanding.


VI.  USE OF PROCEEDS

Any cash proceeds received by the Corporation from the sale of shares of Common
Stock under the Plan shall be used for general corporate purposes.


VII. REGULATORY APPROVALS

     A.   The implementation of the Plan, the granting of any option under the
          Plan and the issuance of any shares of Common Stock (i) upon the
          exercise of any option or (ii) under the Stock Issuance Program shall
          be subject to the Corporation's procurement of all approvals and
          permits required by regulatory authorities having jurisdiction over
          the Plan, the options granted under it and the shares of Common Stock
          issued pursuant to it.

     B.   No shares of Common Stock or other assets shall be issued or delivered
          under the Plan unless and until there shall have been compliance with
          all applicable requirements of Federal and state securities laws,
          including the filing and effectiveness of the Form S-8 registration
          statement for the shares of Common Stock issuable under the Plan, and
          all applicable listing requirements of any stock exchange (or the
          Nasdaq National Market, if applicable) on which Common Stock is then
          listed for trading.


VIII.NO EMPLOYMENT/SERVICE RIGHTS

Nothing in the Plan shall confer upon the Optionee or the Participant any right
to continue in Service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Corporation (or any Parent or
Subsidiary employing or retaining such person) or of the Optionee or the
Participant, which rights are hereby expressly reserved by each, to terminate
such person's Service at any time for any reason, with or without cause.

                            SYNBIOTICS CORPORATION
                            STOCK OPTION AGREEMENT
                            ----------------------


                                  WITNESSETH:
                                  -----------

RECITALS
- --------

A.  Synbiotics Corporation (the "Company") has adopted the 1995 Stock
Option/Stock Issuance Plan (the "Plan") for the purpose of attracting and
retaining the services of selected key employees (including officers and
directors) and consultants and other independent contractors who contribute to
the financial success of the Company or its parent or subsidiary corporations.

B.  Optionee is an individual who is to render valuable services to the Company
or its parent or subsidiary corporations, and this Agreement is executed
pursuant to, and is intended to carry out the purposes of, the Plan in
connection with the Company's grant of a stock option to Optionee.

NOW, THEREFORE, it is hereby agreed as follows:

1.   GRANT OF OPTION.  Subject to and upon the terms and conditions set forth in
     ---------------                                                            
this Agreement, the Company hereby grants to Optionee, as of the grant date (the
"Grant Date") specified in the accompanying Notice of Grant of Stock Option (the
"Notice of Grant"), a stock option to purchase up to that number of shares of
the Company's Common Stock (the "Option Shares") as is specified in the Notice
of Grant.  The Option Shares shall be purchasable from time to time during the
option term at the option price per share (the "Option Price") specified in the
Notice of Grant.

2.   OPTION TERM.  This option shall have a maximum term of ten (10) years
     -----------                                                          
measured from the Grant Date and shall accordingly expire at the close of
business on the expiration date (the "Expiration Date") specified in the Notice
of Grant, unless sooner terminated in accordance with Paragraph 5 or 6.

3.   LIMITED TRANSFERABILITY.  This option shall be neither transferable nor
     -----------------------                                                
assignable by Optionee other than by will or by the laws of descent and
distribution following the Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee.

4.   EXERCISABILITY.  This option shall become exercisable for the Option Shares
     --------------                                                             
in one or more installments as specified in the Notice of Grant.  As the option
becomes exercisable for the Option Shares in one or more such installments,
those installments shall accumulate and the option shall remain exercisable for
the accumulated installments until the Expiration Date or the sooner termination
of the option term under Paragraph 5 or 6 of this Agreement.

5.   TERMINATION OF SERVICE.  The option term specified in Paragraph 2 shall
     ----------------------                                                 
terminate (and this option shall cease to be exercisable) prior to the
Expiration Date should one of the following provisions become applicable:

     (i)  Except to the extent otherwise provided in subparagraphs (ii) through
          (iii) below, should Optionee cease to remain in the Service of the
          Company at any time during the option term, then this option shall not
          remain exercisable for more than a thirty (30)-day period commencing
          with the date of

                                     -A-1-
<PAGE>
 
          such cessation of Service. Upon the expiration of such thirty (30)-day
          period or (if earlier) upon the specified Expiration Date of the
          option term, this option shall terminate and cease to be outstanding.

     (ii) Should Optionee die while in Service or within the thirty (30)-day
          period following his or her cessation of Service, then the personal
          representative of the Optionee's estate or the person or persons to
          whom this option is transferred pursuant to the Optionee's will or in
          accordance with the law of descent and distribution shall have the
          right to exercise this option.  Such right shall lapse, and this
          option shall terminate and cease to remain exercisable, upon the
          earlier of (A) the expiration of the twelve (12)-month period measured
          -------                                                               
          from the date of Optionee's death or (B) the Expiration Date.

     (iii)Should Optionee become permanently disabled and cease by reason
          thereof to remain in Service at any time during the option term, then
          this option shall not remain exercisable for more than a twelve (12)
          month period commencing with the date of such cessation of Service.
          Upon the expiration of such limited period of exercisability or (if
          earlier) upon the Expiration Date, this option shall terminate and
          cease to be outstanding.

     (iv) In no event shall this option be exercisable at any time after the
          specified Expiration Date of the option term.

     (v)  During the limited post-Service period of exercisability determined in
          accordance with subparagraphs (i) through (iii) above, this option may
          not be exercised for more than the number of Option Shares (if any)
          for which this option is, at the time of the Optionee's cessation of
          Service, exercisable in accordance with either the normal exercise
          provisions specified in the Notice of Grant or the special
          acceleration provisions of Paragraph 6 of this Agreement.  However,
          the number of Option Shares purchasable after the Optionee's death
          shall be reduced for any Option Shares purchased by the Optionee after
          his or her cessation of Service but prior to death.

     (vi) For purposes of this Paragraph 5 and for all other purposes under this
          Agreement, the following definitions shall be in effect:

          A.   The Optionee shall be deemed to remain in SERVICE for so long as
               the Optionee continues to render periodic services to the Company
               or any parent or subsidiary corporation, whether as an Employee,
               a non-employee member of the Company's Board of Directors or an
               independent consultant or advisor.

          B.   The Optionee shall be deemed to be an EMPLOYEE and to continue in
               the Company's employ for so long as the Optionee remains in the
               employ of the Company or one or more of its parent or subsidiary
               corporations, subject to the control and direction of the
               employer entity as to both the work to be performed and the
               manner and method of performance.

          C.   The Optionee shall be deemed to be PERMANENTLY DISABLED if the
               Optionee is, by reason of any medically determinable physical or
               mental impairment expected to result in death or to be of
               continuous duration of not less than twelve (12) consecutive
               months or more, unable to perform his or her usual duties for the
               Company or the parent or subsidiary corporation retaining his or
               her services.

          D.   A corporation shall be considered to be a SUBSIDIARY corporation
               of the Company if it is a member of an unbroken chain of
               corporations beginning with the Company, provided

                                     -A-2-
<PAGE>
 
               each such corporation in the chain (other than the last
               corporation) owns, at the time of determination, stock possessing
               50% or more of the total combined voting power of all classes of
               stock in one of the other corporations in such chain.

          E.   A corporation shall be considered to be a PARENT corporation of
               the Company if it is a member of an unbroken chain ending with
               the Company, provided each such corporation in the chain (other
               than the Company) owns, at the time of determination, stock
               possessing 50% or more of the total combined voting power of all
               classes of stock in one of the other corporations in such chain.

6.   CORPORATE TRANSACTION.
     --------------------- 

     A.   For purposes of this Section III, a "Corporate Transaction" shall be
          one or more of the following stockholder-approved transactions:

          (i)  a merger or consolidation in which the Company is not the
               surviving entity, except for a transaction the principal purpose
               of which is to change the State of the Company's incorporation,

          (ii) the sale, transfer or other disposition of all or substantially
               all of the assets of the Company in liquidation or dissolution of
               the Company, or

          (iii)any reverse merger in which the Company is the surviving entity
               but in which securities possessing more than fifty percent (50%)
               of the total combined voting power of the Company's outstanding
               securities are transferred to holders different from those who
               held such securities immediately prior to such merger.

     B.   If this option is to be assumed in connection with the Corporate
          Transaction or is otherwise to continue in effect, then it shall be
          appropriately adjusted, immediately after such Corporate Transaction,
          to apply and pertain to the number and class of securities which would
          have been issuable, in consummation of such Corporate Transaction, to
          an actual holder of the same number of shares of Common Stock as are
          subject to such option immediately prior to such Corporate
          Transaction.  Appropriate adjustments shall also be made to the option
          price payable per share, provided that the aggregate option price
          payable for such securities shall remain the same.

     C.   In the event of any Corporate Transaction in which this option will
          not be assumed or otherwise continued (after such adjustment as may be
          required under paragraph B), the exercisability of this option shall
          automatically accelerate so that, immediately prior to the specified
          effective date for the Corporate Transaction, it shall become fully
          exercisable with respect to the total number of shares of Common Stock
          at the time subject to such option and may be exercised for all or any
          portion of such shares.  This option, to the extent not previously
          exercised, shall terminate upon the consummation of the Corporate
          Transaction and cease to be exercisable, unless it is expressly
          assumed by the successor corporation or parent thereof.

     D.   The exercisability of this option as an incentive stock option under
          the Federal tax laws (if designated as such in the Notice of Grant)
          shall, in connection with any such Corporate Transaction, be subject
          to the applicable dollar limitation of Paragraph 18.

     E.   This Agreement shall not in any way affect the right of the Company to
          adjust, reclassify, reorganize or otherwise make changes in its
          capital or business structure or to merge, consolidate, dissolve,
          liquidate or sell or transfer all or any part of its business or
          assets.

7.   ADJUSTMENT IN OPTION SHARES.
     --------------------------- 

     A.   In the event any change is made to the Common Stock issuable under the
          Plan by reason of any stock split, stock dividend, recapitalization,
          combination of shares, exchange of shares, or other change affecting
          the outstanding Common Stock as a class without the Company's receipt
          of consideration, then appropriate adjustments shall be made to (i)
          the total number of Option Shares subject to this option and (ii) the
          Option Price payable per share in order to reflect such change and
          thereby preclude a dilution or enlargement of benefits hereunder.

     B.   If this option is to be assumed in connection with a Corporate
          Transaction or is otherwise to continue in effect, then this option
          shall, immediately after such Corporate Transaction, be appropriately
          adjusted to apply and pertain to the number and class of securities
          which would have been issued to the Optionee in the consummation of
          such Corporate Transaction had the option been exercised immediately
          prior to such Corporate Transaction.  Appropriate adjustments shall
          also be made to the Option Price payable per share, provided the
                                                              --------    
          aggregate Option Price payable hereunder shall remain the same.

8.   PRIVILEGE OF STOCK OWNERSHIP.  The holder of this option shall not have any
     ----------------------------                                               
of the rights of a stockholder with respect to the Option Shares until such
individual shall have exercised the option, paid the Option Price for the
purchased shares and been issued a stock certificate for such shares.

9.   MANNER OF EXERCISING OPTION.
     --------------------------- 

     A.   In order to exercise this option with respect to all or any part of
          the Option Shares for which this option is at the time exercisable,
          Optionee (or in the case of exercise after Optionee's death, the
          Optionee's executor, administrator, heir or legatee, as the case may
          be) must take the following actions:

          (i)  Execute and deliver to the Secretary of the Company (a) a written
               notice of exercise (the "Exercise Notice"), in substantially the

                       ---------                                             
               the number of Option Shares for which the option is exercised.

          (ii) Pay the aggregate Option Price for the purchased shares in one or
               more of the following alternative forms:

               1.   full payment in cash or check drawn to the Company's order;

               2.   full payment in shares of Common Stock of the Company held
                    by the Optionee for at least six (6) months and valued at
                    Fair Market Value on the Exercise Date (as such terms are

               4.   full payment effected through a broker-dealer sale and

                    employment taxes required to be withheld by the Company by
                    reason of such purchase and (II) shall provide written
                    directives to the Company to deliver the certificates for

                    order to complete the sale transaction; or

               5.   full payment in any other form which the Plan Administrator
                    may, in its discretion, approve at the time of exercise in
                    accordance with the provisions of Paragraph 15 of this
                    Agreement./1/

          (iii)Furnish to the Company appropriate documentation that the
               person or persons exercising the option (if other than the
               Optionee) have the right to exercise this option.

     B.   For purposes of this Agreement, the Fair Market Value of a share of
          Common Stock on any relevant date shall be determined in accordance
          with subparagraphs (i) and (ii) below, and the Exercise Date shall be
          the date on which the executed Exercise Notice is delivered to the
          Company.  Except to the extent the sale and remittance procedure
          specified above is utilized for the exercise of the option, payment of
          the Option Price for the purchased shares must accompany the Exercise
          Notice.  The procedure for measuring Fair Market Value shall be as
          follows:

          (i)  If the Common Stock is not at the time listed or admitted to
               trading on any national stock exchange but is traded on the
               NASDAQ National Market System, Fair Market Value shall be the
               closing selling price per share of Common Stock on the date in
               question, as such price is reported by the National Association
               of Securities Dealers through the NASDAQ National Market System
               or any successor system.  If there is no reported closing selling
               price for the Common Stock on the date in question, then the
               closing selling price on the last preceding date for which such
               quotation exists shall be determinative of Fair Market Value.

          (ii) If the Common Stock is at the time listed or admitted to trading
               on any national stock exchange, then the Fair Market Value shall
               be the closing selling price per share of Common Stock on the
               date in question on the stock exchange determined by the Plan
               Administrator to be the primary market for the Common Stock, as
               such price is officially quoted in the composite tape of
               transactions on such exchange.  If there is no reported sale of
               Common Stock on such exchange on the date in question, then the
               Fair Market Value shall be the closing selling price on the
               exchange on the last preceding date for which such quotation
               exists.

          (iii)If shares of the series of common stock to be valued at the
               time are neither listed nor admitted to trading on any stock
               exchange nor traded in the over-the-counter market, then the fair
               market value shall be determined by the Plan Administrator after
               taking into account such factors as the Plan Administrator shall
               deem appropriate, including one or more independent professional
               appraisals.

     C.   As soon after the Exercise Date as practical, the Company shall mail
          or deliver to or on behalf of the Optionee (or to any other person or
          persons exercising this option) a certificate or certificates
          representing the purchased shares.

10.  COMPLIANCE WITH LAWS AND REGULATIONS.
     ------------------------------------ 

     A.   The exercise of this option and the issuance of the Option Shares upon
          such exercise shall be subject to compliance by the Company and the
          Optionee with all applicable requirements of law relating thereto and
          with all applicable regulations of any stock exchange on which shares
          of the Option Shares may be listed at the time of such exercise and
          issuance.

     B.   In connection with the exercise of this option, Optionee shall execute
          and deliver to the Company such representations in writing as may be

11.  SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided in
     ----------------------

          Date, the number of shares of Common Stock which may without
          stockholder approval be issued under the Plan, then this option shall
          be void with respect to such excess shares, unless stockholder
          approval of an amendment sufficiently increasing the number of shares
          of Common Stock issuable under the Plan is obtained in accordance with
          the provisions of Article 4, Section III of the Plan.

     B.   The inability of the Company to obtain approval from any regulatory
          body having authority deemed by the Company to be necessary to the
          lawful issuance and sale of any Common Stock pursuant to this option
          shall relieve the Company of any liability with respect to the non-
          issuance or sale of the Common Stock as to which such approval shall
          not have been obtained.  The Company, however, shall use its best
          efforts to obtain all such approvals.

     ---------------------------------                                      
Plan shall confer upon the Optionee any right to continue in the Service of the
Company (or any parent or subsidiary corporation of the Company employing or
retaining Optionee) for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Company (or any parent or
subsidiary corporation of the Company employing or retaining Optionee) or the
Optionee, which rights are hereby expressly reserved by each, to terminate the
Optionee's Service at any time for any reason whatsoever, with or without cause.

the terms of this Agreement shall be in writing and addressed to the Company in
care of the Corporate Secretary at the Company's principal corporate offices.
Any notice required to be given or delivered to Optionee shall be in writing and

     -----

discretion.

18.  ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE STOCK OPTION.  In the event
     ------------------------------------------------- ------               
this option is designated as an incentive stock option in the Notice of Grant,
the following terms and conditions shall also apply to the grant:

     A.   This option shall cease to qualify for favorable tax treatment as an
          incentive stock option under the Federal tax laws if (and to the
          extent) this option is exercised for one or more Option Shares:  (i)
          more than three (3) months after the date the Optionee ceases to be an
          Employee for any reason other than death or permanent disability (as
          defined in Paragraph 5) or (ii) more than one (1) year after the date
          the Optionee ceases to be an Employee by reason of permanent
          disability.

     B.   No installment under this option (whether annual or monthly) shall
          qualify for favorable tax treatment as an incentive stock option under
          the Federal tax laws if (and to the extent) the aggregate fair market
          value (determined at the Grant Date) of the Common Stock for which
          such installment first becomes exercisable hereunder will, when added
          to the aggregate fair market value (determined as of the respective
          date or dates of grant) of any earlier installments of Common Stock
          for which this option or any other post-1986 incentive stock options
          granted to the Optionee prior to the Grant Date (whether under the
          Plan or any other option plan of the Company or any parent or
          subsidiary corporations) first become exercisable during the same
          calendar year, exceed One Hundred Thousand Dollars ($100,000) in the
          aggregate.

     C.   Should the exercisability of this option be accelerated upon a
          Corporate Transaction, then this option shall qualify for favorable
          tax treatment as an incentive stock option under the Federal tax laws
          only to the extent the aggregate fair market value (determined at the
          Grant Date) of the Common Stock for which this option first becomes
          exercisable at the time the Corporate Transaction occurs does not,
          when added to the aggregate fair market value (determined as of the
          respective date or dates of grant) of any earlier installments of
          Common Stock for which this option or any other post-1986 incentive
          stock options granted to the Optionee prior to the Grant Date (whether
          under the Plan or any other option plan of the Company or any parent
          or subsidiary corporations) first become exercisable during the
          calendar year in which the Corporate Transaction occurs, exceed One
          Hundred Thousand Dollars ($100,000) in the aggregate.

     D.   To the extent this option should fail to qualify as an incentive stock
          option under the Federal tax laws, the Optionee will recognize
          compensation income in connection with the acquisition of one or more
          Option Shares hereunder, and the Optionee must make appropriate
          arrangements for the satisfaction of all Federal, State or local
          income tax withholding requirements and Federal social security
          employee tax requirements applicable to such compensation income.

19.  ADDITIONAL TERMS APPLICABLE TO A NON-STATUTORY STOCK OPTION.  In the event
     -----------------------------------------------------------               
this option is designated as a non-statutory stock option in the Notice of
Grant, Optionee hereby agrees to make appropriate arrangements with the Company
or parent or subsidiary corporation employing Optionee for the satisfaction of
any Federal, State or local income tax withholding requirements and Federal
social security employee tax requirements applicable to the exercise of this
option.
