change your position, duties, and work location from time to time as it deems
necessary.

     Your compensation of $180,000 per year, less payroll deductions and all

     As equity compensation, you will be given the opportunity to purchase
300,000 shares of the Company's Common Stock, subject to approval by the
Company's Board of Directors. The price of such shares shall be the fair market
value of the stock at the time of the grant, as determined by the Company's
Board of Directors. Any shares so purchased will be subject to vesting on the
following terms: 25% shall vest after one year with the balance vesting equally
on a monthly basis over the next three years; provided, however, that in the
event of a "Change of Control" (as defined below) AND if you are terminated

million dollars ($10,000,000) of invoiced revenue, payable quarterly. This sales
incentive bonus is subject to the Company's review and modification before the
