                       SUPPLEMENTAL RETIREMENT INCOME PLAN

                                     GENERAL

            This is a supplemental retirement income plan for participants in
the Retirement Plan who receive compensation in excess of the compensation which
may be considered by the Retirement Plan under Code Section 401(a)(17). This
Plan has been established primarily for the purpose of providing deferred
compensation for a select group of management or highly compensated employees.

            Specifically, the purpose of this Plan is to provide a retirement
benefit, equal to the excess of:

            (1) the retirement benefit which would be provided by the Retirement
            Plan determined without regard to Code Section 415 or Code Section
            401(a)(17),

            OVER

            (2) the retirement benefit actually provided by the Retirement
            Plan and the Equalization Benefit Plan.

            This Plan is completely separate from the Retirement Plan, the
Enhanced Retirement Income Plan and the Equalization Benefit Plan, is unfunded
for purposes of Title I of the Employee Retirement Income Security Act of 1974,
as amended and is not qualified for special tax treatment under the Code.

                                   ELIGIBILITY

            SECTION 1. A Participant, or the survivor of a Participant who has
not declined the coverage of a survivor's benefit, shall be eligible to
participate in this Plan if such Participant (i) participates in the Retirement
Plan and (ii) receives compensation in excess of the compensation which may be
considered by the Retirement Plan under Code Section 401(a)(17).

                                   ARTICLE II

                                 ADMINISTRATION

            SECTION 1. (a) The Compensation Committee shall have the authority
to administer this Plan. The Compensation Committee may adopt such rules as it
may deem necessary for the proper administration of this Plan and its decision
in all matters involving the interpretation and application of the Plan shall be
final, conclusive, and binding on all parties.

            (b) The Compensation Committee may, in its sole discretion,
designate any persons(s) or committee to administer this Plan. To the extent
provided by the Compensation Committee, such person(s) or committee designated
to administer this Plan shall have the same powers and responsibilities as the
Compensation Committee.

                                   ARTICLE III

                   AMOUNT OF SUPPLEMENTAL RETIREMENT INCOME

            SECTION 1  (a)  A Participant's monthly amount of Supplemental
Retirement Income shall be the excess, if any, of:

            (i) the Participant's monthly retirement benefit, computed by using
            the applicable benefit formula provided in Article V of the
            Retirement Plan and determined without regard to the limitations of
            Code Sections 401(a)(17) and 415,

            OVER

            (ii) the monthly amount of such Participant's retirement benefit
            actually payable under the Retirement Plan and the Equalization
            Benefit Plan.

            (b) Any benefits either payable under, or which have been satisfied
through the purchase of, non-qualified annuities in connection with this
Supplemental Retirement Income Plan and/or the Equalization Benefit Plan shall
be deducted from the amounts payable pursuant to subparagraph (a) above.

            SECTION 2. For purposes of calculating the amount of a Participant's
Supplemental Retirement Income pursuant to Section 1 of this Article III, the
amount of a Participant's monthly retirement benefit under the Retirement Plan
and the Equalization Benefit Plan shall be determined without any adjustment on
account of (i) a survivor's benefit or (ii) an election to receive level
retirement income.

            SECTION 3. If a Participant does not decline the coverage of a

                                      -3-

<PAGE>

survivor's benefit, the monthly amount of Supplemental Retirement Income which
such Participant would otherwise have received shall be reduced by applying the
same factors used in the Retirement Plan in connection with calculating a
survivor's benefit.

            SECTION 4. The monthly amount of Supplemental Retirement Income
payable to the survivor of a Participant shall be calculated in the same manner
that such survivor's benefit is calculated under the Retirement Plan.

                                   ARTICLE IV

                                     VESTING

            SECTION 1. A Participant shall be vested in such Participant's right
to receive Supplemental Retirement Income under this Plan in the same manner and
to the same extent as provided under the Retirement Plan.

                                    ARTICLE V

                                    PAYMENTS

            SECTION 1. A Participant or such Participant's survivor shall
commence receiving Supplemental Retirement Income at such time as the
Participant or survivor commences benefits under the Retirement Plan. Unless a
Participant or survivor elects otherwise, the normal form of payment of a
Participant's Supplemental Retirement Income is as follows:

                  (a) in the calendar year in which the Participant or survivor
is eligible to commence benefits, the Participant or survivor shall begin to
receive monthly payments.

                  (b) in or about January of the calendar year following such
Participant's or survivor's eligibility to commence benefits, the Participant or
survivor shall receive a lump sum payment, representing the remaining amount of

                                      -4-

<PAGE>

the Participant's or survivor's Supplemental Retirement Income.

                  (c) Notwithstanding the foregoing, a Participant or survivor
may elect during the calendar year in which the Participant or survivor
commences benefits to forgo the lump sum payment payable in the following year
and may elect to continue receiving monthly payments. Alternatively, a
Participant or survivor may elect in the calendar year preceding the
Participant's or survivor's commencement of benefits to forgo receiving monthly
payments, in which case the Participant or survivor shall receive a lump sum in
the calendar year in which the Participant or survivor is eligible to commence
benefits.

                  (d) Upon a Participant's death, the Participant's survivor may
cancel any existing election and may make a new one, provided (i) an election to
receive a lump sum payment is made by December 31 prior to the calendar year in
which such lump sum payment is to be made and (ii) an election to revoke the
right to receive a lump sum payment is made by December 31 prior to the calendar
year in which such lump sum was to be paid.

            SECTION 2. Unless otherwise elected, Supplemental Retirement Income
payable in monthly payments under this Plan shall include the coverage of a
survivor's benefit. A survivor's benefit payable from this Plan shall be paid to
that person designated to receive a survivor's benefit under the Retirement
Plan. Supplemental Retirement Income shall in no event be payable after the
death of a Participant who has declined the coverage of a survivor's benefit.

            SECTION 3. Notwithstanding the provisions of Section 1 of this
Article V, a Participant or survivor may elect at any time immediately preceding

                                      -5-

<PAGE>

commencement of benefits to receive substantially equal installments over a
period of at least 2 but not more than 10 years commencing as of the January 1
of the calendar year following such election. If a Participant elects a series
of payments over a period from 2 to 10 years, this election is irrevocable. This
election shall be the same as that made pursuant to the Equalization Benefit
Plan and the Enhanced Retirement Income Plan.

            If a Participant elects a monthly annuity as in the Retirement Plan,
he or she may again elect a series of payments over a period of from 2 to 10
years when the calculation of the lump sum benefit changes. The calculation of
the benefit may change: (i) because of profit sharing or awards paid in the year
following the last year worked or (ii) because the interest rate used to
calculate the lump sum is not available until the November after the monthly
annuity benefit is recalculated.

            The lump sum payment or installment payments described above shall
be calculated using (A) a discount rate for the month of October of the calendar
year preceding the payment of the lump sum or installments equal to the average
of the Moody's Municipal 10 year Aaa Bond Yield Averages and the Moody's
Municipal Long Term Aaa Bond Yield Averages, and (B) the UP-94G Mortality Table.
The Compensation Committee or its designee shall determine the procedures for
such elections and the time and method of payment for payments in accordance
with this Section 3. For Participants who make the election described in this
Section 3, the provisions of Sections 1 and 2 of this Article V shall not apply.

            SECTION 4. Notwithstanding anything in this Plan to the contrary,

                                      -6-

<PAGE>

the Board of Directors may determine that a Participant or survivor shall not be
eligible to receive a lump sum payment.

            SECTION 5. If the Board of Directors determines, after a hearing,
that a Participant who is eligible to receive or is receiving Supplemental
Retirement Income has engaged in any activities which, in the opinion of the
Board, are detrimental to the interests of, or are in competition with the
Corporation or any of its subsidiaries, such Supplemental Retirement Income
shall thereupon be terminated.

                                   ARTICLE VI

benefits under this Plan, or the vested rights of any Participant or survivor.
