Date (as defined below), an amount equal to ten percent (10%) of your 2002 base
salary that would otherwise be payable to you during such period (the "Deferred
Amount").  The Company shall pay you the Deferred Amount in a lump sum payment,
less applicable withholding taxes, on the Expiration Date; provided, that if
                                                           --------

be extended for an additional term to be mutually agreed upon by you and the
Company pursuant to a written agreement (the "Extended Term").

     3.   Effect of Agreement.  This Agreement is limited as specified and shall
          -------------------
not constitute a modification, acceptance or waiver of any other provision of
your Employment Agreement.  Except as otherwise expressly provided in this
letter agreement, the provisions of your Employment Agreement shall remain in
full force and effect.
