                  reviewed annually by the Company's Compensation Committee in
                  the month of December, except that the Base Salary,
                  benchmarked at $500,000 annually for 2004, for the year
                  following the year being reviewed shall not be lower than the
                  Base Salary of the year being reviewed."

                  specified goals agreed upon by Employee and the Company.
                  Employee's performance goals shall be reviewed annually by the
                  Company's Compensation Committee in the month of December. Any
                  payments made to Employee under this paragraph shall be paid
                  in accordance with the Company's customary bonus payment
                  practices, unless otherwise agreed to by the Company and
                  Employee."

                  thereafter, shall be automatically renewed for consecutive
                  twelve (12) month periods, unless this Agreement is terminated
                  by either the Company or Employee upon 60 days' notice in
                  accordance with the notice provisions contained in Paragraph
                  6.6 hereof."

                  through the date of termination, except that health-related
                  benefits shall continue for two years beyond the effective
                  date of termination, unless Employee obtains new employment
                  which offers equal or better health-related benefits coverage
                  in which case the Company provided coverage will terminate as
                  the replacement coverage begins."

         7.       Subsection (b) of Paragraph 5.2, entitled "Termination Without
                  Cause," is amended and restated in its entirety to read as
                  follows:

                           "(b) within seven (7) days of termination, the

                  sum of the following: (i) two additional years of Employee's
                  then-current base salary plus Cost-of-living Assistance, (ii)
                  Employee's annual car allowance, and (iii) the bonus Employee
                  could have earned had he continued employment with the Company
                  through the end of the calendar year in which termination
                  occurs with the amount of the bonus pro-rated for the portion
                  of the year through the date of termination. This payment
                  shall be made in a lump sum, less applicable withholding,"

                                        2



         8.       Subsection (c) of Paragraph 5.2, entitled "Termination Without
                  Cause," is amended and restated in its entirety to read as
                  follows:

                           "(c) the Company shall cause all of the Employee's
                  outstanding stock options to become immediately vested. In
                  addition, the exercise period of all stock options granted to
                  the Employee after the Amended Anniversary Date occurring in
                  2003 (the "Subsequent Stock Options") shall be extended for a
                  period of two years from the date of termination, provided,
                  however, that all stock options granted to the Employee prior
                  to the Amended Anniversary Date occurring in 2003 (the
                  "Previous Stock Options") shall be governed by the provisions
                  of Section 5.2(c) of the Original Agreement. Notwithstanding
                  the foregoing, such extension of the exercise periods of the
                  Subsequent Stock Options and the Previous Stock Options,
                  respectively, shall not exceed the original terms of such
                  options."

         9.       All other terms, conditions and restrictions contained in the
                  Agreement shall continue in full force and effect.

         10.      This Amendment may be signed in one or more counterparts, each
                  of which shall be deemed an original, but all of which
                  together shall constitute one instrument.

         Pursuant to Section 6.5 of the Agreement, this Amendment, when fully
executed and delivered, shall constitute an amendment thereto.
