                                    AMENDMENT

     1.           Section 6.2.3 of the Plan, as previously amended, is further
amended by replacing it with the following new Section 6.2.3:

                         "6.2.3 The amount of each level payment for the Initial
                  Payment Period, if any, shall be calculated using the balance
                  in the Account as of the beginning of the Initial Payment
                  Period and amortizing such balance over the remaining Overall
                  Payment Period (a) using an assumed interest rate equal to the
                  rate of one-year United States Treasury notes for each
                  Participant receiving payments of benefits prior to December
                  8, 1999, said rate to be determined once each Plan Year and to
                  be the rate in effect as of the September 30 immediately
                  preceding the payment period to which it applies, as published
                  by Solomon Smith Barney Inc., or any successor thereto, or as
                  determined by the Chief Financial Officer of the Company (the
                  "Assumed Interest Rate"), and (b) using an assumed interest
                  rate of zero percent (0%) for all other Participants. The
                  amount of each level payment for each Calendar Year Payment
                  Period shall be calculated by taking the balance in the
                  Account as of November 30 of the calendar year immediately
                  prior to such Calendar Year Payment Period, subtracting the
                  benefit payments made during the portion of such preceding
                  calendar year following November 30, and amortizing the
                  difference over the remaining Overall Payment Period (x) using
                  the Assumed Interest Rate for each participant receiving
                  payments of benefits prior to December 8, 1999, and (y) using
                  an assumed interest rate of zero percent (0%) for all other
                  Participants. The amount of each level payment for the
                  Remainder Payment Period, if any, shall be calculated by
                  taking the balance in the Account as of November 30 of the
                  calendar year immediately prior to the Remainder Payment
                  Period, subtracting the benefit payments made during the
                  portion of such preceding

                  calendar year following November 30, and amortizing the
                  difference over the Remainder Payment Period using an assumed
                  interest rate of zero percent (0%) per annum. If the actual
                  crediting rate for the Remainder Payment Period is more
                  than zero percent, the additional gain resulting from the
                  difference shall be paid to the Participant in a single
                  payment within six months after the last day of the Remainder
                  Payment Period."

         2.       Except as modified in this Amendment No. 6, the Plan, as
previously amended, shall remain in full force and effect, including the
Company's right to amend or terminate the Plan as set forth in Article 9 of the
Plan.
