                                  AMENDMENT ONE
                                     TO THE
                    FIRST FINANCIAL EXECUTIVES' SUPPLEMENTAL
                                 RETIREMENT PLAN

               (As Amended and Restated Effective January 1, 1997)

     WHEREAS, the First Financial Executives' Supplemental Retirement Plan
("Plan") was established by First Financial Corporation ("Corporation") for the
benefit of a select group of management and highly compensated employees; and

     WHEREAS, pursuant to Section 7.1 of the Plan, the Corporation has reserved
the right to amend the Plan; and

     WHEREAS, the Corporation desires to amend the Plan, to provide that the
supplemental benefit is determined by including in the Participant's
compensation, for purposes of calculating the Supplemental Plan benefit, the
amount of salary deferrals to the First Financial Executives' Deferred
Compensation Plan, which are otherwise excluded from the definition of
compensation under the First Financial Corporation Employees' Pension Plan;

     NOW, THEREFORE, BE IT RESOLVED, that the Plan be, and it hereby is, amended
effective as of January 1, 2000, in the following particulars:

     1. Section 3.1 of the Plan is hereby amended by deleting the first sentence
and replacing it with the following:

     "A Participant, or, in the event of his death, his beneficiary, shall be
     entitled to benefits under the Plan if the Participant's employment with
     the Employer terminates and the benefits payable under the Pension Plan to
     the Participant or his beneficiary are reduced because of: (i) the maximum
     benefit limitation imposed by Code Section 415, (ii) the Code Section
     401(a)(17) limitation on the amount of the Participant's compensation that
     may be considered for purposes of determining his benefits under the
     Pension Plan, or (iii) the exclusion of participant salary deferrals to the
     First Financial Executives' Deferred Compensation Plan from the definition
     of compensation used to determine benefits under the Pension Plan."

     2. Section 3.2 of the Plan is hereby amended by deleting the first sentence
and replacing it with the following:

     "The total amount of benefits payable under this Plan to a Participant or,
     in the event of his death, to his beneficiary, shall equal the difference,
     if any, between the amount of

     benefit that would have been paid under the Pension Plan if the limitations
     imposed by Code Section 415, Code Section 401(a)(17), the exclusion of
     participant deferrals to the First Financial Executives' Deferred
     Compensation Plan from the definition of compensation used to determine
     benefits under the Pension Plan, and the exclusion of Mr. Lowery from the
     Pension Plan during its 1996 plan year, did not apply, and the amount of
     benefit which is actually payable under the Pension Plan to the Participant
     or his beneficiary."

     All other provisions of the Plan shall remain in effect.

     As evidence of its adoption of this Amendment One, First Financial
Corporation has caused this instrument to be signed by its officers thereunder
duly authorized this ______ day of ______________, 2000, but effective as of
January 1, 2000.
