         This is to confirm that, with the approval the Board of Directors, this

as follows:
         1.       Effective January 1, 2003, your annual base salary shall be
                  increased to $260,000.00.
         2.       In the event of the termination of your employment for any
                  reason, other than cause or your resignation without cause,
                  you and your eligible dependents shall continue to receive all
                  Welfare Benefits provided for in your Employment Agreement
                  until at least August 12, 2005.
         3.       In the event of the termination of your employment for any

                  the period during which your options shall be exercisable
                  shall be extended until the fourth anniversary date of

         For purposes of this Agreement, your failure to agree to or the

Employment Agreement of January 8, 2001 are hereby ratified and confirmed and
remain in full force and effect.
