successor plan thereto (to the extent paid), and (ii) the vested contributions

purposes of determining the amount of offset attributable to this Section 2.1.4,
Company contributions (or allocations, in the case of clause (ii) above) shall
be deemed to earn interest at an annual rate of 6%, compounded annually, from
the date of such contribution (or allocation) until the date it is actually paid

and except as otherwise set forth in Section 2.2.2 or 2.2.3, if the Executive's
employment terminates on or after his Normal Retirement Date, the Company will

employment terminates and ending with the payment for the month in which his

Executive's designated beneficiary, if any or (ii) if there is no designated
beneficiary or the designated beneficiary dies before a total of 120 payments
have been made to the Executive and the designated beneficiary, to the
Executive's estate. Such monthly benefit (the "Normal Retirement Benefit") shall
be an amount equal to (A) the product of his Final Average Pay, Benefit
Percentage, and his Vesting Percentage, less (B) his Qualified Pension Benefits.

                           2.2.2 TERMINATION FOLLOWING CHANGE IN CONTROL.

which the first day of the month after his employment terminates precedes the
Executive's attainment of age 65.

                           2.2.3 TERMINATION WITHOUT CAUSE OR FOR GOOD REASON.
Subject to Section 2.2.7, and except as otherwise provided in Section 2.2.2,
upon termination of the Executive's employment at any time by the Company other
than for Cause or by the Executive for Good Reason, the Company will pay the
Execu tive, as soon as practicable following such date of termination, an amount
equal to the actuarial present value of a monthly benefit starting on the first
of the month after his employment terminates, computed under Section 2.2.1 using
a Vesting Percent age of 100% and Continuous Service equal to the Executive's
actual Continuous Service at the time his employment terminates plus 12 months,
with such monthly benefit reduced by one quarter of one percent (1/4%) per
payment for each full calendar month by which the first day of the month after
his employment terminates precedes the Executive's attainment of age 65.

                           2.2.4 TERMINATION FOR CAUSE. No benefits shall be
payable hereunder with respect to the Executive if his employment is terminated
by the Company for Cause.

                           2.2.5 DISABILITY. If the Executive's employment with
the Company or any Affiliate terminates on account of Disability, the Company
shall pay the Executive a monthly benefit in an amount (computed using a Vesting
Percentage of 100%) equal to (i) the product of his Final Average Pay and
Benefit Percentage less (ii) his Qualified Pension Benefits. The benefit so
determined shall be payable, without actuarial or other reduction to reflect
commencement of payment before his Normal Retirement Date, beginning on the
first date of the month next following the last month with respect to which the
Executive is entitled to payments under the Company's long term disability plan
(or, if earlier, such time as the Executive shall elect not to receive such
payments) and ending with the payment for the month in which his death occurs
or, if later, after the


                                       5
<Page>

payment of 120 such payments. Any such payments made after the death of the
Executive shall be made (i) to the Execu tive's designated beneficiary, if any
or (ii) if there is no designated beneficiary or the designated beneficiary dies
before a total of 120 payments have been made to the Executive and the
designated beneficiary, to the Executive's estate.

                           2.2.6 OTHER TERMINATION. Subject to Section 2.2.7,
and except as otherwise set forth in Sections 2.2.2, 2.2.3 or 2.2.5, if the

Company will pay the Executive a monthly benefit starting on the date elected by
the Executive, but no earlier than the first of the month after his attainment
of age 55, and ending with the payment for the month in which his death occurs
or, if later, after the payment of 120 such payments. Any such payments made
after the death of the Executive shall be made (i) to the Executive's designated
beneficiary, if any or (ii) if there is no desig nated beneficiary or the
designated beneficiary dies before a total of 120 payments have been made to the
Executive and the designated beneficiary, to the Executive's estate. Such
monthly benefit shall be calculated and paid in accordance with Section 2.2.1
hereof, reduced by one quarter of one percent (1/4%) per payment for each full
calendar month by which the benefit commencement date precedes the Executive's
attainment of age 65.

                           2.2.7 OPTIONAL FORMS OF BENEFIT. In lieu of the form
of benefit prescribed in Section 2.2.1 and Section 2.2.6, the Executive may
elect to receive his benefit hereunder, as soon as practicable following the
date of his termination of employment, in a cash lump sum, the amount of which
shall equal the actuarial present value of, in the case of Section 2.2.1, his
Normal Retirement Benefit and, in the case of Section 2.2.6, the reduced monthly
benefit he would have received thereunder. In lieu of the lump sum form of
benefit prescribed in Sections 2.2.2. and 2.2.3, the Executive may elect to
receive his benefit hereunder as a monthly benefit, computed under Section 2.2.1
and reduced by one quarter of one percent (1/4%) per payment for each full
calendar month by which the benefit commencement date precedes the Executive's
attainment of age 65, starting on the first of the month after his employment
terminates and ending with the payment for the month in which his death occurs
or, if later, after the payment of 120 such payments. Any such payments made
after the death of the Executive shall be made (i) to the Executive's designated
beneficiary, if any or (ii) of there is no designated beneficiary or the
designated beneficiary dies before a total of 120 payments have been made to the
Executive and the designated beneficiary, to the Executive's estate. Any
election to change to or from the lump sum form of benefit that is made by the
Executive less than one year preceding the Executive's date of termination shall
not be given effect; PROVIDED, HOWEVER, that the


                                       6
<Page>

foregoing shall be inapplicable with respect to (i) any election made by the
Executive within 30 days of the date of this Agreement and (ii) any election
with respect to the Executive's benefit under Section 2.2.2 to the extent such
election is made at least 90 days prior to a Change in Control or at any time
prior to the Company entering into an agreement the consummation or shareholder
approval of which would constitute a Change in Control.

                  2.3 SPECIAL BENEFIT. If it shall be determined by a final
administra tive decision of the Internal Revenue (which is not appealed by the
Executive) or by a final decision of a court of competent jurisdiction (which is
not appealed by the Executive) that the value of all or any part of any benefit
contemplated by this Agreement is includable in the income of the Executive
prior to the actual receipt of such benefit, the Company shall make a special
payment to the Executive, in discharge of the actuarially equivalent value
(based upon the actuarial factors in effect when benefits other than the benefit
described in this Section 2.3 commence to be paid to the Executive hereunder) of
any benefits otherwise due hereunder (and such other benefit shall be reduced to
reflect the actuarial value of any such special payment made pursuant to this
Section 2.3), in an amount equal to the Executive's estimated federal, state and
local income tax liabilities related to such inclusion and to the inclusion in
income of such special payment. The Executive shall have no obligation to appeal
any determination made by the Internal Revenue Service or the decision of any
such court.

                  2.4 NO DUPLICATION. Except as provided in Section 2.3 hereof,
in no event shall benefits become payable to the Executive under more than one
Section of this Article II.


                                   ARTICLE III

                                SURVIVOR BENEFITS

                  3.1 POST-RETIREMENT SURVIVOR BENEFIT. Notwithstanding any
provision hereof to the contrary, the Executive may elect, at any time prior to
commencement of his benefits under Article II (and may revoke or modify any such
election and/or make a new election, in each case at any time and from time to
time prior to commencement of his benefits under Article II), to have his
benefit paid in the from of a joint and survivor annuity pursuant to which (i)
payment of the Execu tive's benefit will be made in accordance with Article II
and (ii) if the Executive dies after payment of his benefits under Article II
has


                                       7
<Page>

started, the Company shall pay a monthly benefit to the Executive's designated
beneficiary, starting on the first of the month immediately following the month
in which the Executive dies or, if later, with the month immediately following
the last month for which a payment is made to such beneficiary under Article II,
and ending with the payment for the month in which the death of such designated
beneficiary occurs. Such monthly benefit shall be an amount equal to 50% or
100%, as elected by the Executive, of the monthly benefit the Executive was
receiving under the Agreement prior to his death. If the Executive makes such
election, the benefit payable to the Executive under Article II hereof shall be
reduced to reflect the actuarial equivalence of the additional Post-Retirement
Survivor Benefit so elected by the Executive.

                  3.2 PRE-RETIREMENT SURVIVOR BENEFIT. Notwithstanding any
provision hereof to the contrary, the Executive may elect at any time (and may
revoke or modify any such election and/or make a new election, in each case at
any time and from time to time prior to commencement of his benefits under
Article II) that, in the event the Executive dies before distribution of his
benefits under Article II has started, the Company shall pay a monthly benefit
to the Executive's designated beneficiary, starting on the first of the month
immediately following the month in which the Executive dies, but in no event
earlier than the date on which the Execu tive would have been eligible to
commence receipt of his benefits under Article II had he terminated employment
on the day immediately preceding his death, and ending with the payment for the
month in which the death of such designated beneficiary occurs. Such monthly
benefit shall be an amount equal to 50% or 100%, as elected by the Executive, of
the monthly benefit the Executive would have received had he terminated
employment on the day immediately preceding his death and commenced benefits on
the date on which the benefit under this Section 3.2 commences. If the Executive
makes such election, the benefit payable to the Executive under Article II
hereof shall be reduced to reflect the actuarial equivalence of the additional
Pre-Retirement Survivor Benefit so elected by the Executive.

                                   ARTICLE IV
