          (b)   No Participant who is a Key Employee shall accrue any further

     4.   The last paragraph of Section 3.1 of the Plan is hereby amended to
read as follows:

     For purposes of determining the Supplemental Retirement Benefit described
     above:

          (i)   The amount described in (a) above for any Participant who
     commences participation in the Plan after January 1, 2001 shall be
     multiplied by a fraction, the numerator of which shall be years of Credited
     Service not to exceed 20, and the denominator of which shall be 20,
     determined as of the date of the Participant's termination of employment

          (ii)  A Participant's Final Average Earnings described in (a) above
     shall be determined as of October 1, 2001, and shall be adjusted by an
     amount equal to 25% of the percentage increase in the Participant's base
     salary in effect on September 30, 2001 compared to the Participant's base
     salary in effect on the date of the Participant's termination of employment
     for any reason, including Retirement, Disability or death.

          (iii) In determining a Participant's Qualified Retirement Benefit, the
     Participant's Cash Account Balance shall not be credited with any Credits

     shall be deemed to have received his Cash Account Balance on October 1,
     2001; and in the case of a Participant who is a Grandfathered Participant,
     the Grandfathered Benefit shall be calculated considering the Participant's
     Final Average Earnings, Credited Service (not in excess of 20 years) and

          3.2   KEY EMPLOYEES. Effective as of October 1, 2001, no Participant
     who is a Key Employee of the Company as described in Section 2.2 shall
     accrue any further Supplemental Retirement Benefit. The Supplemental
     Retirement Benefit of a Participant who is such a Key Employee shall be a
     monthly amount equal to the difference between (a) and (b) below:

          (a)   The monthly amount of the Qualified Retirement Benefit accrued
     as of October 1, 2001 to which the Participant would have been entitled
     under the Qualified Retirement Plan without giving effect to the
     limitations imposed by Section 401(a)(17) or any other section of the Code;

     as of October 1, 2001 and payable to the Participant under the Qualified
     Retirement Plan at October 1, 2001.

     For purposes of determining the Supplemental Retirement Benefit described
     above:

          (i)   For calculating the Qualified Retirement Benefit under Section
     3.2(a) only, any Key Employee Participant who was over the age of 55 on
     January 1, 2000 shall be deemed a "Grandfathered Participant" as defined
     under the Qualified Retirement Plan.

          (ii)  A Participant's Final Average Earnings shall be determined as of
     October 1, 2001, and shall not be based on or include Compensation earned
     by a Participant after such date.

          (iii) In determining a Participant's Qualified Retirement Benefit, the
     Participant's Cash Account Balance shall not be credited with Pay Credits
     for any period of time on or after October 1, 2001, and in the case of a
     Participant who is a Grandfathered Participant, the Grandfathered Benefit
     shall be calculated considering the Participant's Final Average Earnings,
     Credited Service (not in excess of 20 years) and Social Security offset as
     of October 1, 2001.

          (iv)  The amounts described in (a) and (b) shall be computed in the
     form of an annuity payable over the Participant's lifetime only.

     6.   Section 3.3 of the Plan is hereby amended to add a final sentence to
the end thereof to read as follows:

     Notwithstanding the foregoing provisions of this Section 3.3, no
     Participant who is a Key Employee of the Company as described in Section
     2.2 shall accrue any further Supplemental Surviving Spouse Benefit on or
     after October 1, 2001.

     7.   The second sentence of Section 7.2 of the Plan is hereby amended to
delete the reference to "Sections 3.4 through 3.8" and insert "Sections 3.4 and
3.5" in lieu thereof.

     8.   Article VII of the Plan is hereby amended by adding a new Section 7.4
thereto to read as follows:

          7.4   TERMINATION OF PARTICIPATION. The Company, in its sole
     discretion, shall have the right to terminate the participation in the Plan
     or any portion thereof of any Executive Officer or Key Employee whose
     initial participation in the Plan was designated by the Compensation
     Committee, upon recommendation of management, pursuant to Section 1.6 or

     Account, as applicable to such Participant, determined as of the date of
     termination of participation, shall be made to such Participant, his
     Surviving Spouse or beneficiaries either (i) in the manner and at the time
     described in Articles III and IV of the Plan; or (ii) in the sole
     discretion of the Company in a lump sum payment as soon as practicable
     following such termination of participation. No additional Supplemental
     Retirement Benefit or Surviving Spouse Benefit shall be earned by such
     Participant after termination of his participation in the Plan with respect
     to such benefits, and no additional credits of Supplemental Salary Deferral
     Contributions, Supplemental Company Contributions or Supplemental Profit
     Sharing Contributions shall be made to the Accounts of such Participant
     after termination of his participation in the Plan with respect to such
     benefits, but the Company shall continue to credit earnings, gains and
     losses to existing Accounts of such Participant pursuant to Section 4.5
     until the balances of such Accounts have been fully distributed to the
     Participant or his beneficiaries.

     IN WITNESS WHEREOF, this Amendment No. 2 has been executed on this 10th day
of October, 2001.
