                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


    The accompanying March 31, 2003 and 2002 consolidated financial statements
are unaudited. The December 31, 2002 consolidated financial statements are as
reported in the First Financial Corporation (the Corporation) 2002 annual
report. The following notes should be read together with notes to the
consolidated financial statements included in the 2002 annual report filed with
the Securities and Exchange Commission as an exhibit to Form 10-K.

1. The significant accounting policies followed by the Corporation and its
subsidiaries for interim financial reporting are consistent with the accounting
policies followed for annual financial reporting. All adjustments which are, in
the opinion of management, necessary for a fair statement of the results for the
periods reported have been included in the accompanying consolidated financial
statements and are of a normal recurring nature. The Corporation reports
financial information for only one segment, banking.

2. A loan is considered to be impaired when, based upon current information and
events, it is probable that the Corporation will be unable to collect all
amounts due according to the contractual terms of the loan. Impairment is
primarily measured based on the fair value of the loan's collateral. The
following table summarizes impaired loan information:

                          FIRST FINANCIAL CORPORATION


ITEMS 2. and 3. Management's Discussion and Analysis of Financial Condition and
Results of Operations and Quantitative and Qualitative Disclosures About Market
Risk

     The purpose of this discussion is to point out key factors in the
Corporation's recent performance compared with earlier periods. The discussion
should be read in conjunction with the financial statements beginning on page
four of this report. All figures are for the consolidated entities. It is
presumed the readers of these financial statements and of the following
narrative have previously read the Corporation's annual report for 2002.

     Forward-looking statements contained in the following discussion are based
on estimates and assumptions that are subject to significant business, economic
and competitive uncertainties, many of which are beyond the Corporation's
control and are subject to change. These uncertainties can affect actual results
and could cause actual results to differ materially from those expressed in any
forward-looking statements in this discussion.


                          Summary of Operating Results


     Net income for the three months ended March 31, 2003 was $7.0 million, a
4.5% improvement from the $6.7 million in the same period in 2002. Basic
earnings per share increased to $1.04 for the first quarter of 2003 compared to
$0.98 for 2002, an 6.1% improvement.

     The primary components of income and expense affecting net income are
discussed in the following analysis.

Net Interest Income

     The Corporation's primary source of earnings is net interest income, which
is the difference between the interest earned on loans and other investments and
the interest paid for deposits and other sources of funds. Net interest income
decreased to $18.9 million in the first three months of 2003 from $19.5 million
in the same period of 2002, a 2.8% decrease. This was the result of a decrease
of $23.1 million in average interest earning assets and a reduced net interest
margin for 2003. The net interest margin decreased from 4.09% in 2002 to 4.02%
in 2003, a 1.7% decrease driven by a greater decline in the yield on earning
assets than in the average cost of funds.

Non-Interest Income

     The financial results for the quarter were driven by a $1.9 million, or
30.9%, increase over comparable 2002 non-interest income. Mortgage interest
rates continue to hover at all-time lows. Selling these low fixed-rate mortgages
in the secondary market has been the over-riding strategy of the Corporation.
Net cash gains on these sales in 2003 account for $492 thousand of the $1.9
million increase.

Non-Interest Expenses

     Non-interest expenses increased $597 thousand, or 4.0%. This would include
one additional month of expenses for First Community in 2003 than in 2002, due
to the acquisition occurring on February 1, 2002. Other cost increases would
include merit increases in salaries and higher fringe benefit costs.





                                                                               8

Allowance for Loan Losses

   The Corporation's provision for loan losses increased to $2.2 million for the
first three months of 2003 compared to $1.9 million in the same period of 2002.
At March 31, 2003, the allowance for loan losses was 1.56% of total loans, an
increase from 1.48% at December 31, 2002. Net chargeoffs for the first three
months of 2003 were $1.7 million compared to only $1.5 million for the same
period of 2002. Based on management's analysis of the current portfolio, an
evaluation that includes consideration of historical loss experience and
potential loss exposure on identified problem loans, management believes the
allowance of $21.8 million at March 31, 2003 is adequate.


UNDER-PERFORMING LOANS

     Under-performing loans consist of (1) nonaccrual loans on which the
ultimate collectability of the full amount of interest is uncertain, (2) loans
which have been renegotiated to provide for a reduction or deferral of interest
or principal because of a deterioration in the financial position of the
borrower, and (3) loans past due ninety days or more as to principal or
interest. A summary of under-performing loans at March 31, 2003 and December 31,
2002 follows:

INTEREST RATE SENSITIVITY AND LIQUIDITY

     First Financial Corporation has established risk measures, limits and
policy guidelines for managing interest rate risk and liquidity. Responsibility
for management of these functions resides with the Asset Liability Committee.
The primary goal of the Asset Liability Committee is to maximize net interest
income within the interest rate risk limits approved by the Board of Directors.




                                                                               9

INTEREST RATE RISK

     Management considers interest rate risk to be the Corporation's most
significant market risk. Interest rate risk is the exposure to changes in net
interest income as a result changes in interest rates. Consistency in the
Corporation's net interest income is largely dependent on the effective
management of this risk.

     The Asset Liability position is measured using sophisticated risk
management tools, including earning simulation and market value of equity
sensitivity analysis. These tools allow management to quantify and monitor both
short-term and long-term exposure to interest rate risk. Simulation modeling
measures the effects of changes in interest rates, changes in the shape of the
yield curve and the effects of embedded options on net interest income. This
measure projects earnings in the various environments over the next three years.
It is important to note that measures of interest rate risk have limitations and
are dependent on various assumptions. These assumptions are inherently uncertain
and, as a result, the model cannot precisely predict the impact of interest rate
fluctuations on net interest income. Actual results will differ from simulated
results due to timing, frequency and amount of interest rate changes as well as
overall market conditions. The Committee has performed a thorough analysis of
these assumptions and believes them to be valid and theoretically sound. These
assumptions are continuously monitored for behavioral changes.

     The Corporation from time to time utilizes derivatives to manage interest
rate risk. Management continuously evaluates the merits of such interest rate
risk products but does not anticipate the use of such products to become a major
part of the Corporation's risk management strategy.

     The table below shows the Corporation's estimated sensitivity profile as of
March 31, 2003. The change in interest rates assumes a parallel shift in
interest rates of 100 and 200 basis points. Given a 100 basis point increase in
rates, net interest income would increase 3.85% over the next 12 months and
increase 7.90% over the following 12 months. Given a 100 basis point decrease in
rates, net interest income would decrease 2.41% over the next 12 months and
decrease 6.37% over the following 12 months. These estimates assume all rate
changes occur overnight and management takes no action as a result of this
change.

</TABLE>


     Typical rate shock analysis does not reflect management's ability to react
and thereby reduce the effect of rate changes, and represents a worst-case
scenario.

Liquidity Risk

     Liquidity is measured by each bank's ability to raise funds to meet the
obligations of its customers, including deposit withdrawals and credit needs.
This is accomplished primarily by maintaining sufficient liquid assets in the
form of investment securities and core deposits. The Corporation has $6.6
million of investments that mature throughout the coming 12 months. The
Corporation also anticipates $126.7 million of principal payments from
mortgage-backed securities. Given the current rate environment, the Corporation
anticipates $26.5 million in securities to be called within the next 12 months.
With these sources of funds, the Corporation currently anticipates adequate
liquidity to meet the expected obligations of its customers.

Financial Condition

     Comparing the first quarter of 2003 to 2002, average loans are down $30.9
million due primarily to continued refinancing and sales of fixed-rate
mortgages. Average deposits were up $11.9 million. These resources were used to
pay down average bank borrowings by $42.5 million. Average shareholders' equity
increased $22.5 million, or 10.1%. Strong financial performance and increased
unrealized gains on securities pushed book value per share up 11.2% to $36.34 in
2003 from $32.68 in 2002. Book value per share is calculated by dividing the
total equity by the number of shares outstanding.

Capital Adequacy

     As of March 31, 2003, the most recent notification from the respective
regulatory agencies categorized the Corporation and its subsidiary banks as well
capitalized under the regulatory framework for prompt corrective action. To be
categorized as
