substantial personal enrichment of the Optionee, (ii) the conviction of a
felony, (iii) a willful act by the Optionee that constitutes gross misconduct
and that is injurious to the Company, (iv) for a period of not less than thirty
(30) days following delivery to the Optionee of a written demand for performance

willful and deliberate on the Optionee's part or (v) as otherwise provided in an
Option Agreement.

        (i) Any "person" (as such term is used in Sections 13(d) and 14(d) of

of the Company representing more than fifty percent (50%) of the total voting
power represented by the Company's then outstanding voting securities entitled

in the voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity or the entity that controls such
surviving entity) at least fifty percent (50%) of the total voting power
represented by the voting securities of the Company, such surviving entity or
entity that controls such surviving entity outstanding immediately after such
merger or consolidation; or

        (iv) The consummation of the sale or disposition by the Company of all
or substantially all of the Company's assets.

B. Article VII "Termination of Service" is amended by deleting the previous
Section 7.3 and replacing it in its entirety as follows:

        7.3 Termination for Cause. Unless otherwise provided by the Board and
set forth in the Option Agreement, if the Optionee's employment shall be
terminated for Cause, the Optionee's right to exercise any unexercised portion

C. Article VII "Termination of Service" is amended by adding the following new
Sections 7.6 and 7.7:

        7.6 Change in Control. Notwithstanding the exercise or vesting periods
set forth in the Plan or the Option Agreement, exercise of an Option shall
always be subject to the following:

                             If the Company or any successor thereto terminates
                             the Optionee's employment without Cause within
                             twelve (12) months following a Change in Control,
                             the Optionee's Options, and restricted stock
                             acquired upon exercise of the Optionee's Options or
                             otherwise granted under the Plan shall become 100%
                             vested and exercisable; provided, however, that no
                             such acceleration shall occur in the event that it
                             would preclude accounting for any business
                             combination of the Company involving a Change in
                             Control as a "pooling of interests."

        7.7 Excise Tax.

                             Notwithstanding any other provisions of the Plan or
                             any Option Agreement, or other related agreement,
                             in the event that any payment or benefit received
                             or to be received by the Optionee (whether pursuant
                             to the terms of the Plan or other plan, arrangement
                             or agreement with the Company, any person whose
                             actions result in a Change in Control or any person
                             affiliated with the Company or such person) (all
                             such payments and benefits being hereinafter called
                             "Total Payments") would be subject (in whole or
                             part), to any excise tax imposed under Section 4999
                             of the Code (the "Excise Tax"), then, after taking
                             into account any reduction in the Total Payments
                             provided by reason of Section

<PAGE>   3

                             280G of the Code in such other plan, arrangement or
                             agreement, the payment or benefit received or to be
                             received by the Optionee (whether pursuant to the
                             terms of the Plan, any Option Agreement, or other
                             related agreement) shall be reduced, to the extent
                             necessary so that no portion of the Total Payments
                             is subject to the Excise Tax but only if (A) the
                             net amount of such Total Payments, as so reduced
                             (and after subtracting the net amount of federal,
                             state and local income taxes on such reduced Total
                             Payments) is greater than or equal to (B) the net
                             amount of such Total Payments without such
                             reduction (but after subtracting the net amount of
                             federal, state and local income taxes on such Total
                             Payments and the amount of Excise Tax to which the
                             Optionee would be subject in respect of such
                             unreduced Total Payments).

                             Unless the Company and the Optionee otherwise agree
                             in writing, any determination required under this
                             Section shall be made in writing by the Company's
                             independent public accountants (the "Accountants"),
                             whose determination shall be conclusive and binding
                             upon the Optionee and the Company for all purposes.
                             For purposes of making the calculations required by
                             this Section, the Accountants may make reasonable
                             assumptions and approximations concerning
                             applicable taxes and may rely on reasonable, good
                             faith interpretations concerning the application of
                             Sections 280G and 4999 of the Code. The Company and
                             the Optionee shall furnish to the Accountants such
                             information and documents as the Accountants may
                             reasonably request in order to make a determination
                             under this Section. The Company shall bear all
                             costs the Accountants may reasonably incur in
                             connection with any calculations contemplated by
                             this Section.<PAGE>   1

                                    AMENDMENT
                                       TO

(30) days following delivery to the Optionee of a written demand for performance
from the Company that describes the basis for the Company's belief that the

or substantially all of the Company's assets.

B. Section 8 "Adjustment of Shares" is hereby amended by changing the heading to

or other related agreement, exercise of an Option or purchase of shares shall be
subject to the following:

                             If the Company or any successor thereto terminates
                             the Optionee's or Purchaser's employment without
                             Cause within twelve (12) months following a Change
                             in Control, the Optionee's Options or Purchaser's
                             Shares, as the case may be and any restricted stock
                             acquired upon exercise of the Optionee's Options or

                             become vested; provided, however, that no such
                             acceleration shall occur in the event that it would
                             preclude accounting for any business combination of
                             the Company involving a Change in Control as a
                             "pooling of interests."

               (e)  Excise Tax.

                             Notwithstanding any other provisions of the Plan or
                             any Stock Option Agreement or Stock Purchase
                             Agreement, or other related agreement, in the event
                             that any payment or benefit received or to be
                             received by the Optionee or Purchaser, as
                             applicable (whether pursuant to the terms of the
                             Plan or other plan, arrangement or agreement with
                             the Company, any person whose actions result in a
                             Change in Control or any person affiliated with the
                             Company or such person) (all such payments and
                             benefits being hereinafter called "Total Payments")
                             would be subject (in whole or part), to any excise
                             tax imposed under Section 4999 of the Code (the
                             "Excise Tax"), then, after taking into account any
                             reduction in the Total Payments provided by reason
                             of Section 280G of the Code in such other plan,
                             arrangement or agreement, the payment or benefit
                             received or to be received by the Optionee or

<PAGE>   3

                             case may be (whether pursuant to the terms of the
                             Plan, any Stock Option Agreement, Stock Purchase
                             Agreement or other related agreement) shall be
                             reduced, to the extent necessary so that no portion
                             of the Total Payments is subject to the Excise Tax
                             but only if (A) the net amount of such Total
                             Payments, as so reduced (and after subtracting the
                             net amount of federal, state and local income taxes
                             on such reduced Total Payments) is greater than or
                             equal to (B) the net amount of such Total Payments
                             without such reduction (but after subtracting the
                             net amount of federal, state and local income taxes
                             on such Total Payments and the amount of Excise Tax
                             to which the Optionee would be subject in respect
                             of such unreduced Total Payments).

                             Unless the Company and the Optionee otherwise agree
                             in writing, any determination required under this
                             Section shall be made in writing by the Company's
                             independent public accountants (the "Accountants"),
                             whose determination shall be conclusive and binding
                             upon the Optionee or Purchaser, as applicable, and
                             the Company for all purposes. For purposes of
                             making the calculations required by this Section,
                             the Accountants may make reasonable assumptions and
                             approximations concerning applicable taxes and may
                             rely on reasonable, good faith interpretations
                             concerning the application of Sections 280G and
                             4999 of the Code. The Company and the Optionee or
                             Purchaser, as applicable, shall furnish to the
                             Accountants such information and documents as the
                             Accountants may reasonably request in order to make
                             a determination under this Section. The Company
                             shall bear all costs the Accountants may reasonably
                             incur in connection with any calculations
                             contemplated by this Section.
