Parties;

     WHEREAS, Executive shall receive continued employment with the Company as

     all of the Executive's unvested stock options or restricted stock awards
     then outstanding, would constitute "parachute payments" within the meaning
     of Section 280G of the Internal Revenue Code of 1986, as amended (the
     "CODE"), and would be subject to the excise tax imposed by Section 4999 of
     the Code, then the Executive's severance and other benefits will be
     payable, at the Executive's election, either in full or in such lesser
     amount as would result, after taking into account the applicable federal,
     state and local income taxes and the excise tax imposed by Section 4999 of
     the Code, in the Executive's receipt on an after-tax basis of the greatest
     amount of severance and other benefits.

     IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of
