the future. The cash payment will be paid to Mr. van der Wansem upon the first
to occur of the following events: (i) a "change of control event" as defined in
Section 409A of the Internal Revenue Code, (ii) if Mr. van der Wansem's

months following the date of termination, or (iii) June 30, 2007. If the Company
is unable to make the cash payment in cash (as determined in good faith by the
Board of Directors and after consultation with Mr. van der Wansem), (i) the
Board of Directors may elect to make the cash payment using a combination of
cash and shares of the Company's common stock or (ii) Mr. van der Wansem may
elect to receive the entire value of the cash payment in shares of the Company's
common stock.
