                  terminated by the Company other than for Cause in accordance
                  with Section 3.1(c), the Company shall pay Employee the
                  present value of his total compensation, including without
                  limitation, Base Salary, any bonus (based on the last bonus
                  paid, earned, or accrued) and the value of any benefits then
                  received or entitled to be received by Employee for the
                  balance of the Initial Term together with any Renewal Term in
                  place pursuant to the three year rolling basis referred to in
                  Section 1.1 above, discounted at the per annum rate equal to
                  the prime or base rate published in THE WALL STREET JOURNAL on

                  Payment shall be made on the Date of Termination and with such
                  deductions as are in accordance with the Company's regular
                  payroll practices in effect from time to time while such

         IN WITNESS WHEREOF, Employee and Company's authorized representative
have executed this Amendment on the date above written.
