                         ENHANCED RETIREMENT INCOME PLAN

                                     GENERAL

            This is an enhanced retirement income plan for participants in the
Retirement Plan who receive a retirement benefit under the Retirement Plan which
is limited by Code Section 415 or 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),
if

               (a)  average monthly Compensation included Awards and base salary
                    deferred pursuant to the terms of the Compensation Deferral
                    Program or any succesor or predecessor program, and/or

               (b)  all Awards, whether deferred or not, were averaged
                    separately from Base Compensation (as defined in the
                    Retirement Plan);

                    OVER

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

            This Plan is completely separate from the Retirement Plan, the
Supplemental Retirement Income Plan and the Equalization Benefit Plan, is
unfunded for purposes of Title I of the Employee Retirement Income Security Act

<PAGE>

of 1974, as amended, and is not qualified for special tax treatment under the
Code.

                                    ARTICLE I

                                   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 receives a retirement benefit from
the Retirement Plan which is limited by Code Section 401(a)(17) or Code Section
415, or is a participant in the Compensation Deferral Program.

                                   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 person(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 ENHANCED RETIREMENT INCOME

            SECTION 1.

          (a) A Participant's monthly Enhanced Retirement Income shall be
computed by using the applicable formula provided in Article V of the Retirement
Plan; provided, however, that average monthly Compensation shall be determined
without regard to Code Section 415 and Code Section 401(a)(17) and shall be
computed by determining the sum of the following amounts:

            (i)   the larger of:

                  (I)  1/36 of a Participant's Base Salary related to the three
                       full calendar years in which such Base Salary was largest
                       during the ten full calendar years next preceding the
                       date of death or retirement, or

                  (II) 1/36 of a Participant's Base Salary for the thirty-six
                       (36) full calendar months next preceding the date of
                       death or retirement; and

            (ii)  1/36 of the Participant's Awards related to the three full
                  calendar years in which such Awards were the largest during
                  the ten full calendar years next preceding the date of death
                  or retirement; provided, that the calendar years in which the
                  Participant was hired or terminated employment shall each be
                  considered a full calendar year for the purposes of this
                  clause (ii); REDUCED BY

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

                                       3

<PAGE>

          (b) For purposes of this Section 1, an "Award" will be related to the
calendar year in which a Participant performed the services for which the Award
was paid.

          (c) For purposes of this Section 1, the amount of "Base Salary"
received in any calendar month shall be calculated in the same manner in which
average monthly Compensation used to compute pension benefits under the
Retirement Plan is calculated (determined without regard to Incentive
Compensation, as defined therein); provided, however, that Base Salary shall
also include any base salary deferred by a Participant pursuant to the terms of
the Compensation Deferral Program, in the calendar year in which it would
otherwise have been paid.

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

          (e) Notwithstanding the foregoing, the amount of a Participant's
Enhanced Retirement Income shall include any additional non-qualified retirement
benefits resulting from agreements entered into by the Corporation and the
Participant.

            SECTION 2. If the Enhanced Retirement Income payable to a
Participant under this Plan commences before the grant to such Participant of an
Award (whether or not deferred) which may be used to determine average monthly
Compensation under Section 1 of this Article III, the monthly amount of Enhanced
Retirement Income payable hereunder shall be recalculated after such Award is
granted (whether or not deferred).

            SECTION 3. For purposes of calculating the amount of a Participant's
Enhanced Retirement Income pursuant to Section 1 of this Article III, the amount
of a Participant's monthly retirement income and monthly pension under the
Retirement Plan, the Equalization Benefit Plan and the Supplemental Retirement

                                       4

<PAGE>

Income shall be determined without any adjustment on account of (i) a survivor's
benefit or (ii) an election to receive level retirement income.

            SECTION 4. If a Participant does not decline the coverage of a
survivor's benefit, the monthly amount of Enhanced 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
benefits.

            SECTION 5. The monthly amount of Enhanced Retirement Income payable
to the eligible 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 will be vested in such Participant's right
to receive Enhanced Retirement Income under the 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 Enhanced 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
Enhanced Retirement Income is as follows:

                                       5

<PAGE>

                  (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
the Participant's or survivor's Enhanced 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, Enhanced 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. Enhanced Retirement Income shall in no event be payable after the death of
a Participant who has declined the coverage of a survivor's benefit.

                                       6

<PAGE>

            SECTION 3. Notwithstanding the provisions of Section 1 of this
Article V, a Participant or survivor may elect at any time immediately preceding
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 Supplemental 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,
the Board of Directors may determine that a Participant or survivor shall not be
eligible to receive a lump sum payment.

                                       7

<PAGE>

            SECTION 5. If the Board of Directors determines, after a hearing,
that a Participant who is eligible to receive or is receiving Enhanced
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 Enhanced Retirement Income shall
thereupon be terminated.

                                   ARTICLE VI
