                  B = $20,000. + [$20,000. x 2 x (NI - T)]
                                             ------------

                  B = the bonus earned in such year.

                  T = the Target for such year.

                           (C) If the Net Income of the Company for such year is
         equal to or greater than 125% of the Target, the Employee shall be

         shall be entitled to a bonus as calculated below:

                  B = $20,000. - [$20,000. x 4 x (T - NI)]
                                             ------------
                                                  T
                  where:

                  B = the bonus earned in such year.

                  T = the Target for such year.

                  NI = the Net Income of the Company for such year.

                           (E) If the Net Income of the Company for such year is
         equal to or less than 75% of the Target, the Employee shall not be
         entitled to a bonus.

                           (F) for any calendar year regarding which the
         Employee is entitled to a bonus under the foregoing provisions of this
         clause (2) but during which year the Employee did not work the entire
         calendar year, unless otherwise provided herein, the Employee shall be
         entitled to a bonus equal to the product of the bonus, as calculated
         under the foregoing provisions, multiplied by a fraction, the
         numerator of which is the number of months during such calendar year
         that the Employee was employed with the Company and the denominator of
         which is twelve."

         2. Except as expressly amended hereby, all of the terms and conditions
of the Employment Agreement shall continue in full force and effect.
