Section 3.2 - Qualification of Incentive Stock Options
-----------   ----------------------------------------

              No Incentive Stock Option shall be granted unless such Option,
when granted, qualifies as an "incentive stock option" under Section 422 of the

Section 3.3 - Granting of Options
-----------   -------------------

              (a)  The Board shall from time to time, in its absolute
discretion:

              (i)  Determine which Employees are key Employees and select from
     among the key Employees (including those to whom Options have been
     previously granted under the Plan) such of them as in its opinion should be
     granted Options; and

              (ii)  Determine the number of shares to be subject to such Options
     granted to such selected key Employees, and determine whether such Options
     are to be Incentive Stock Options or Non-Qualified Options; and

              (iii)  Determine the terms and conditions of such Options,
     consistent with the Plan.

     (b)  Upon the selection of a key Employee to be granted an Option, the
Board shall instruct the Secretary to issue such Option and may impose such
conditions on the grant of such Option as it deems appropriate.  Without
limiting the generality of the preceding sentence, the Board may, in its
discretion and on such terms as it deems appropriate, require as a condition on
the grant of an Option to an Employee that the Employee surrender for
cancellation some or all of the unexercised Options which have been previously
granted to him.  An Option the grant of which is conditioned upon such surrender
may have an option price lower (or higher) than the option price of the
surrendered Option, may cover the same (or a lesser or greater) number of shares
as the surrendered Option, may contain such other terms as the Board deems
appropriate and shall be exercisable in accordance with its terms, without
regard to the number of shares, price, option period or any other term or
condition of the surrendered Option.

                                   ARTICLE IV

Section 4.1 - Option Agreement
-----------   ----------------

              Each Option shall be evidenced by a written Stock Option
Agreement, which shall be executed by the Optionee and an authorized Officer of
the Company and which shall contain such terms and conditions as the Board shall
determine, consistent with the Plan. Stock Option Agreements evidencing
Incentive Stock Options shall contain such terms and

                                       5
<PAGE>
 
conditions as may be necessary to qualify such Options as "incentive stock
options" under Section 422 of the Code.

Section 4.2 - Option Price
-----------   ------------

              (a)  The price of the shares subject to each Option shall be set
by the Board; provided, however, that the price per share shall be not less than
100% of the fair market value of such shares on the date such Option is granted;
provided, further, that, in the case of an Incentive Stock Option, the price per
share shall not be less than 110% of the fair market value of such shares on the
date such Option is granted in the case of an individual then owning (within the
meaning of Section 424(d) of the Code) more than 10% of the total combined
voting power of all classes of stock of the Company, any Subsidiary or any
Parent Corporation.

              (b)  For purposes of the Plan, the fair market value of a share of
the Company's Common Stock as of a given date shall be: (i) the closing price of
a share of the Company's Common Stock on the principal exchange on which shares
of the Company's Common Stock are then trading, if any, on the day previous to
such date, or, if shares were not traded on the day previous to such date, then
on the next preceding trading day during which a sale occurred; or (ii) if such
Common Stock is not traded on an exchange but is quoted on NASDAQ or a successor
quotation system, (1) the last sales price (if the Company's Common Stock is
then listed as a National Market Issue under the NASD National Market System) or
(2) the mean between the closing representative bid and asked prices (in all
other cases) for the Company's Common Stock on the day previous to such date as
reported by NASDAQ or such successor quotation system; or (iii) if such Common
Stock is not publicly traded on an exchange and not quoted on NASDAQ or a
successor quotation system, the mean between the closing bid and asked prices
for the Company's Common Stock, on the day previous to such date, as determined
in good faith by the Board; or (iv) if the Company's Common Stock is not
publicly traded, the fair market value established by the Board acting in good
faith.

             (b)  Subject to the provisions of Sections 4.3(a), 4.3(c), 4.3(d)
and 7.3, Options shall become exercisable at such times and in such installments
(which may be cumulative) as the Board shall provide in the terms of each
individual Option; provided, however, that by a resolution adopted after an
Option is granted the Board may, on such terms and conditions as it may
determine to be appropriate and subject to Sections 4.3(a),

                                       6

4.3(c), 4.3(d) and 7.3, accelerate the time at which such Option or any portion
thereof may be exercised.

              (c)  No portion of an Option which is unexercisable at Termination
of Employment shall thereafter become exercisable.

              (d)  Notwithstanding any other provision of this Plan, in the case
of an Incentive Stock Option, the aggregate fair market value (determined at the
time the Incentive Stock Option is granted) of the shares of the Company's stock
with respect to which "incentive stock options" (within the meaning of Section
422 of the Code) are exercisable for the first time by the Optionee during any
calendar year (under the Plan and all other incentive stock option plans of the
Company, any Subsidiary and any Parent Corporation) shall not exceed $100,000.

Section 4.4 - Expiration of Options
-----------   ---------------------

              (a)  No Option may be exercised to any extent by anyone after the
first to occur of the following events:

              (i)  The expiration of ten years from the date the Option was

              (ii)  With respect to an Incentive Stock Option in the case of an
     Optionee owning (within the meaning of Section 424(d) of the Code), at the
     time the Incentive Stock Option was granted, more than 10% of the total
     combined voting power of all classes of stock of the Company, any
     Subsidiary or any Parent Corporation, the expiration of five years from the
     date the Incentive Stock Option was granted; or

              (iii)  Except in the case of any Optionee who is disabled (within
     the meaning of Section 22(e)(3) of the Code), the expiration of three
     months from the date of the Optionee's Termination of Employment for any
     reason other than such Optionee's death unless the Optionee dies within
     said three-month period; or

              (iv)  In the case of an Optionee who is disabled (within the
     meaning of Section 22(e)(3) of the Code), the expiration of one year from
     the date of the Optionee's Termination of Employment for any reason other
     than such Optionee's death unless the Optionee dies within said one-year
     period; or

              (v)  The expiration of one year from the date of the Optionee's
     death.

              (b)  Subject to the provisions of Section 4.4(a), the Board shall
provide, in the terms of each individual Option, when such Option expires and
becomes unexercisable; and (without limiting the generality of the foregoing)
the Board may provide in the terms of

                                       7
<PAGE>
 
individual Options that said Options expire immediately upon a Termination of
Employment for any reason.

Section 4.5 - Consideration
-----------   -------------

              In consideration of the granting of an Option, the Optionee shall
agree, in the written Stock Option Agreement, to remain in the employ of the
Company, a Parent Corporation or a Subsidiary for a period of at least one year
after the Option is granted.  Nothing in this Plan or in any Stock Option
Agreement hereunder shall confer upon any Optionee any right to continue in the
employ of the Company, any Parent Corporation or any Subsidiary or shall
interfere with or restrict in any way the rights of the Company, its Parent
Corporations and its Subsidiaries, which are hereby expressly reserved, to
discharge any Optionee at any time for any reason whatsoever, with or without
cause.

Section 4.6 - Adjustments in Outstanding Options
-----------   ----------------------------------

              In the event that the outstanding shares of the stock subject to
Options are changed into or exchanged for a different number or kind of shares
of the Company or other securities of the Company by reason of merger,
consolidation, recapitalization, reclassification, stock split-up, stock
dividend or combination of shares, the Board shall make an appropriate and
equitable adjustment in the number and kind of shares as to which all
outstanding Options, or portions thereof then unexercised, shall be exercisable,
to the end that after such event the Optionee's proportionate interest shall be
maintained as before the occurrence of such event.  Such adjustment in an
outstanding Option shall be made without change in the total price applicable to
the Option or the unexercised portion of the Option (except for any change in
the aggregate price resulting from rounding-off of share quantities or prices)
and with any necessary corresponding adjustment in Option price per share;
provided, however, that, in the case of Incentive Stock Options, each such
adjustment shall be made in such manner as not to constitute a "modification"
within the meaning of Section 424(h)(3) of the Code.  Any such adjustment made
by the Board shall be final and binding upon all Optionees, the Company and all
other interested persons.

Section 4.7 - Merger, Consolidation, Acquisition, Liquidation or Dissolution

after the merger or consolidation of the Company with or into another
corporation, the acquisition by another corporation or person of all or
substantially all of the Company's assets or 80% or more of the Company's then
outstanding voting stock or the liquidation or dissolution of the Company; and
if the Board so provides, it may, in its absolute discretion and on such terms
and conditions as it deems appropriate, also provide, either by the terms of
such Option or by a resolution adopted prior to the occurrence of such merger,
consolidation, acquisition, liquidation or dissolution, that,

                                       8

Section 4.3(a), Section 4.3(b) and/or any installment provisions of such Option,
but subject to Section 4.3(d).

              (d)  Such representations and documents as the Board, in its
absolute discretion, deems necessary or advisable to effect compliance with all

including, without limitation, placing legends on share certificates and issuing
stop-transfer orders to transfer agents and registrars; and

              (e)  In the event that the Option or portion thereof shall be
exercised pursuant to Section 5.1 by any person or persons other than the

portion thereof prior to fulfillment of all of the following conditions:

              (a)  The admission of such shares to listing on all stock
exchanges on which such class of stock is then listed; and

              (b)  The completion of any registration or other qualification of
such shares under any state or federal law or under the rulings or regulations

any part of an Option unless and until certificates representing such shares

elapsed from (but excluding) the date that such Option was granted. The Board,
in its absolute discretion, may impose such other restrictions on the
transferability of the shares purchasable upon the exercise of an Option as it
deems appropriate. Any such other restriction shall be set forth in the
respective Stock Option Agreement and may be referred to on the certificates
evidencing such shares. The Board may require the Employee to give the Company
prompt notice of any disposition of shares of stock, acquired by exercise of an
Incentive Stock Option, within two years from the date of granting such Option
or one year after the transfer of such shares to such Employee. The Board may
direct that the certificates evidencing shares acquired by exercise of an
Incentive Stock Option refer to such requirement to give prompt notice of
disposition.

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

Section 7.1 - Options Not Transferable
-----------   ------------------------

              No Option or interest or right therein or part thereof shall be
liable for the debts, contracts or engagements of the Optionee or his successors
in interest or shall be subject to disposition by transfer, alienation,
anticipation, pledge, encumbrance, assignment or any other means whether such
disposition be voluntary or involuntary or by operation of law by judgment,
levy, attachment, garnishment or any other legal or equitable proceedings
(including bankruptcy), and any attempted disposition thereof shall be null and
void and of no effect; provided, however, that nothing in this Section 7.1 shall
prevent transfers by will or by the applicable laws of descent and distribution.

Section 7.2 - Amendment, Suspension or Termination of the Plan
-----------   -------------------------------------------------

              The Plan may be wholly or partially amended or otherwise modified,
suspended or terminated at any time or from time to time by the Board.  However,
without approval of the Company's shareholders given within 12 months before or
after the action by the Board, no action of the Board may, except as provided in
Section 2.3, increase any limit imposed in Section 2.1 on the maximum number of
shares which may be issued on exercise of Options, materially modify the
eligibility requirements of Section 3.1, reduce the minimum Option price
requirements of Section 4.2(a) or extend the limit imposed in this Section 7.2
on the period during which Options may be granted.  Neither the amendment,
suspension nor termination of the Plan shall, without the consent of the holder
of the Option, impair any rights or obligations under any Option theretofore
granted.  No Option may be granted during any period of suspension nor after
termination of the Plan, and in no event may any Option be granted under this
Plan after the first to occur of the following events:

              (a)  The expiration of ten years from the date the Plan is adopted
by the Board; or

              (b)  The expiration of ten years from the date the Plan is
approved by the Company's shareholders under Section 7.3.

Section 7.3 - Approval of Plan by Shareholders

              This Plan will be submitted for the approval of the Company's
shareholders within 12 months after the date of the Board's initial adoption of
the Plan.  Options may be

                                       12

granted prior to such shareholder approval; provided, however, that such Options
shall not be exercisable prior to the time when the Plan is approved by the
shareholders; provided, further, that if such approval has not been obtained at
the end of said 12-month period, all Options previously granted under the Plan
shall thereupon be cancelled and become null and void.

Section 7.4 - Effect of Plan Upon Other Option and Compensation Plans
-----------   -------------------------------------------------------

              The adoption of this Plan shall not affect any other compensation
or incentive plans in effect for the Company, any Parent Corporation or any
Subsidiary. Nothing in this Plan shall be construed to limit the right of the
Company, any Parent Corporation or any Subsidiary (a) to establish any other
forms of incentives or compensation for employees of the Company, any Parent
Corporation or any Subsidiary or (b) to grant or assume options otherwise than
under this Plan in connection with any proper corporate purpose, including, but
not by way of limitation, the grant or assumption of options in connection with
the acquisition by purchase, lease, merger, consolidation or otherwise, of the
business, stock or assets of any corporation, firm or association.
