the Company confirms: its prior grant to the Executive on May 10, 1999 to
purchase 150,000 shares of stock at the closing price on that date with 50,000
shares vesting on May 10, 2000, 50,000 shares vesting on May 10, 2001 and 50,000
shares vesting on May 10, 2002; and its prior grant to the Executive on
September 24, 1999 in respect of salary deferral by the Executive of 31,741
shares of stock with a strike price of $1.78 with 10,580 vested immediately upon
grant, 10,580 vesting on September 24, 2000 and 10,581 vesting on September 24,
2001; and the prior grant to the Executive of options on December 3, 1999 to
purchase 150,000 shares of stock at the closing price on that grant date, with
50,000 shares vesting immediately upon grant, 50,000 shares vesting on December
3, 2000 and 50,000 shares vesting on December 3, 2001. The shares vesting on
December 3, 2000 and December 3, 2001 shall only vest if the Executive has
performed his duties in a manner reasonably satisfactory to the Compensation
Committee of the Board of Directors of the Company. In the event that the Board
of Directors of the Company determines that the performance of the Executive is
not reasonably satisfactory, it shall so inform the Executive in writing setting
forth the reasons for the unsatisfactory performance. If the Compensation
Committee determines that the Executive has not satisfied the performance
criteria, it will notify the Executive within thirty (30) days of the applicable
December 3 grant and the Executive shall have the right for a period of thirty
(30) days to cure the performance deficiencies to the reasonable satisfaction of
the Compensation Committee. All of the options set forth in this

                                       5

<PAGE>   6

Section 4(b) shall fully vest upon the occurrence of a Change in Control or
upon a termination of this Agreement by the Executive for Good Reason.

         (c)      At the sole discretion of the Board of Directors of the
Company the Executive may be paid, in cash, Common Stock, options to purchase
Common Stock or any combination thereof, an annual bonus for the Company's
fiscal years of 2001 and 2002, in such an amount, if any, and based upon such
criteria as the Board of Directors of the Company Compensation Committee may
from time to time consider appropriate based upon the Executive's performance
during each such year (the "Discretionary Bonus"). The options granted pursuant
to this Section 4(b) shall be vested as of the date hereof, and shall be
subject to all of the terms and provisions of the Company's 1997 Stock Option
Plan, the Company's 1999 Stock Option Plan or any subsequently enacted stock
option plan, as applicable, except that they may be exercised in any amount at
any time after being vested until three (3) years from date of termination of
employment and shall be irrevocable during that period. Should there not be
sufficient options available or useable under said stock option Plans then,
unless otherwise agreed to by the Executive, the Company will nonetheless issue
said options to Executive, outside of said Plans, and register the shares of
Common Stock underlying the options within 180 days of their being issued.

         (d)      As additional consideration for Executive's services to the
Company hereunder, the Company shall pay Executive an annual bonus (the
"Performance Bonus"), based upon the Company's performance during the
Employment Term, commencing with the fiscal year from January 1, 2000 through
December 31, 2000, and for each fiscal year during the Employment Term
thereafter, if earned, in the form of options to purchase shares of the
Company's Common Stock, in an amount equal to one quarter of one percent
(0.25%) of the Revenue Goal (as hereinafter defined), if the Revenue Goal is
attained; or (ii) three-eighths of one percent (0.375%) of the increase, if
any, in the Market Cap from January 1 through December 31 of the applicable
fiscal year during the Employment Term. For purposes hereof, the term "Revenue
Goal" shall mean eighty-five percent (85%) of the Company's revenue goal for
each fiscal year during the Employment Term occurring after the Initial Period,
as set forth in its business plan for such year; provided that for the fiscal
year from January 1, 2000 through December 31, 2000 the Revenue Goal shall be
$20,000,000. For purposes hereof, the Market Cap Test shall be based on the
average of the number of shares outstanding and closing prices for the
Company's Common Stock for the thirty (30) days ended December 31 of the
applicable year compared to the same thirty (30) day period in the prior year.
The calculation of whether any Performance Bonus is due for any fiscal year
during the Employment Term occurring thereafter, as applicable, shall be made
by the Board of Directors promptly after the end of the fiscal year in respect
of the Market Cap test and upon the Company's issuance of its audited annual
financial statements in respect of the Revenue Goal test. The Performance
Bonus, if earned, shall be paid in the form of options to purchase shares of
the Company's Common Stock valued at an exercise price equal to the average of
the closing market price of the shares of the Company's Common Stock for the
thirty (30) days prior to the end of the applicable fiscal year. Any options
issued in respect of the Performance Bonus shall be subject to all of the terms
and provisions of the Company's 1999 Stock Option Plan or, if no shares are
available under such

                                       6

<PAGE>   7

Plan, or any subsequently enacted stock option plan, as applicable, except that
they may be exercised in any amount, at any time after being vested until three
(3) years from date of termination of employment and are irrevocable during
that period. Should there not be sufficient options available or useable under
said Stock Option Plan, the Company will use its best efforts to cause a new
Stock Option Plan to be adopted which cover the shares.

         (e)      Notwithstanding anything set forth in Section 4(c), in no
event shall the options granted to the Executive, if any, as the Performance
Bonus with respect to any fiscal year during the Employment Term exceed the
greater of (i) options exercisable into 100,000 shares of Common Stock or (ii)
one third of one percent (0.33%) of the Company's outstanding shares of capital
stock.

         (f)      Should there be a Change of Control of the Company or any
other transaction in which the Company is not the surviving entity during the
Employment Term, then as part of that transaction, the Company will require the
surviving entity to modify the Agreement in an equitable manner to provide the
Executive the same type of benefits that he is entitled to earn pursuant to
Section 4(c) of this Agreement.

         Section 5. Benefits, Vacation. (a) During the Employment Term, the
Executive shall be entitled to such insurance and health and medical benefits
as are generally made available to the senior executives of the Company, as a

the conditions of coverage attendant to such plans.

         (b)      During each contract year of the Employment Term, the
Executive shall be entitled to four (4) weeks of vacation. The Executive shall

concurrence of the Company based upon the then current business needs and
activities of the Company. Vacation shall accrue if unused during the term of
employment.

         (c)      During the Employment Term, the Executive shall be eligible
to participate in the profit sharing and other benefit plans that the Company
from time to time makes available to the senior executives of the Company as a
group, subject to the terms, provisions and conditions of such plans,
including, without limitation, any vesting periods and eligibility criteria.

         (d)      During the Employment Term, the Company shall pay to the

public policies applied in the jurisdiction in which enforcement is sought.
