any reason you shall not be entitled to any payments, benefits, damages, or

of employment. Under this Plan, the Restricted Stock will be sold to you at a
nominal price of $0.01 per share. Under this Plan, the Restricted Stock will be

employment thereafter. The Stock Option shall be fully exercisable after four
years of continued employment from the date of grant, but as long as you are
employed by the Company, you shall have up to 10 years from the date of grant to
exercise the Option.

         (c)    Agreements:  The Restricted Stock and the Stock Option shall be
                ----------

any reason, other than as described in subparagraphs (b) and (c) below, you
shall be entitled to receive a severance payment (the "Severance Payment") from
the Company for a period of 12 months maximum.  The Severance Payment will be
equal to your then current annual salary.  However, you shall not be entitled to
any Severance Payment if your employment is terminated for "cause." For purposes

impairment, (ii) a willful act by you which constitutes gross misconduct and
which is injurious to the Company, (iii) a willful breach by you of a material
provision of this agreement or (iv) a material and willful violation of a
federal or state law or regulation applicable to the business of the Company.
No act, or failure to act, by you shall be considered "willful" unless committed
without good faith and without a reasonable belief that the act or omission was
in the Company's best interests.

(i) your position or employment is involuntarily terminated, or (ii) your
duties, responsibilities or compensation are materially reduced, you shall be
entitled to receive a Severance Payment from the Company in an amount to two
times the Severance Payment defined in subparagraph (a) above. For this purpose,
the term "Change of Control" of the Company means (i) the acquisition by any
person or persons of 50% or more of the total voting power represented by the
Company's then outstanding voting securities or (ii) a transaction that involves
the sale of all or substantially all of the assets of the Company or the merger
of the Company with or into another corporation involving a 50% or more change
in the ownership of the total voting power represented by the Company's then
outstanding voting securities or (iii) a change in the composition of the Board
of Directors of the Company as a result of which fewer than a majority of the
incumbent directors are directors who either (A) had been directors of the
Company 24 months prior to such change or (B) were elected or nominated for
election to the Board of the Company with the affirmative vote of at least a
majority of the directors who had been directors of the Company 24 months prior
to such change and who were still in office at the time of election or
nomination.

         (c)  Voluntary Resignation: If you voluntarily resign or terminate your
              ---------------------                                         
employment, then you shall not be entitled to any Severance Payment or other
benefits. The Company shall have no obligation to provide any compensation or
benefits on account of your death, or for periods following your death.

         (d)  Severance: Any Severance Payment to which you have become entitled
              ---------                                                 
hereunder will be subject to applicable tax withholding and will be paid semi-
monthly in accordance with the Company's normal payroll. The Severance Payment
shall be in lieu of any further payment to you. Notwithstanding the foregoing,
the Severance Payment will not reduce or offset any benefits you may be entitled
to under the specific terms of any Company benefit plans during the Severance
Payment period.

     6.  Miscellaneous.
         ------------- 

         (a)  Entire Agreement: Other than under the Company's Stock Option and
