Executive in writing that its obligations under the Employment Agreement would be fulfilled and that the Employment Agreement would not be renewed;



D. The Executive hereby specifically acknowledges and agrees that the provisions of Sections 7, 8 and 9 of the Employment Agreement (as those provisions

effective date of termination from the Company is June 11, 2005 (the Termination Date).

withholdings:

4. Stock Options. Provided this Agreement becomes binding on the Executive, the parties agree as
follows with respect to the stock options previously granted to the Executive (the Executive Options):

| | --- | --------------------------------------------------------------------------------------------



| | (B) | Options (issued in March 2005) to purchase 107,314 shares of common stock that were not vested as of the Termination Date will continue to vest on their stated terms and conditions
as long as the Executive continues to perform services under the Agreement.

| | (C) | In the event that the SAB Agreement is terminated without cause (as defined in the SAB Agreement) by the Company prior to June 11, 2007, immediately upon such
termination, all unvested options will vest automatically and will become fully exercisable.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (D) | At such time as the SAB Agreement terminates or expires, the Executive shall be subject to the vesting and exercise provisions of the respective Stock Option Plan (each a
Plan) under which each option was issued, unless the Company terminates the SAB Agreement without cause, in which event the options will become fully vested as described above. Each Plan provides for extended vesting and exercise rights
upon termination subject to certain terms and conditions as described in each Plan. The parties agree that the termination date for purposes of determining extended vesting and exercise rights shall be the date on which the Executive ceases to
perform services under the SAB Agreement

accordance with their original vesting schedule for a period of 12 months following the date of expiration or termination, and any options that vest during such 12-month period may be exercised by the Executive for a period of one year following the
date of such vesting.
