                           FIRST FINANCIAL CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     The accompanying June 30, 2005 and 2004 consolidated financial statements
are unaudited. The December 31, 2004 consolidated financial statements are as
reported in the First Financial Corporation (the "Corporation") 2004 annual
report. The following notes should be read together with notes to the
consolidated financial statements included in the 2004 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:

                          Summary of Operating Results


     Net income for the three months ended June 30, 2005 was $5.0 million, a
21.1% decrease from the $6.3 million for the same period in 2004. Basic earnings
per share for the quarter ended June 30, 2005 decreased to $0.37, a 21.3%
decrease from the $0.47 for the same period in 2004. The year-to-date net income
at June 30, 2005 was $11.3 million or $0.84 per share, compared to $17.0 million
or $1.26 per share for the same period in 2004. These represent 33.6% and 33.3%
decreases in net income and earnings per share, respectively.

     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
increased $935,000 to $36.6 million in the first six months of 2005 from $35.7
million in the same period in 2004. During the same period the net interest
margin increased from 3.77% in 2004 to 3.95% in 2005, a 18 basis point increase
driven by a greater increase in the yield on earning assets than in the average
cost of funds. The net interest income for the three months ended June 30, 2005
was $18.3 million, an increase of $525,000 over the $17.8 million for the same
period of 2004.

Non-Interest Income

     Non-interest income decreased $5.4 million to $15.5 million at June 30,
2005 from $20.9 million for the six months ended June 30, 2004. This was largely
the result of a non-taxable gain of $4.1 million on a life insurance benefit
received in the first quarter of 2004. Security gains the six months ended June
30, 2005 were $25 thousand compared to $423 thousand for the same period of 2004
Non-interest income for the three months ended June 30, 2005 was $7.8 million
compared to $8.3 million for the same period of 2004. Other services charges and
fees account for $435 thousand of the $514 thousand decrease.

Non-Interest Expenses

     Non-interest expenses decreased $286 thousand from $31.4 million for the
six months ended June 30, 2004 to $31.1 million for the same period of 2005. The
non-interest expense for the three months ended June 30, 2005 was $15.8 million
compared to $15.9 million for the same period of 2004. This is due mainly to
cost savings from consolidating our affiliated banks into one bank.

Allowance for Loan Losses

     The Corporation's provision for loan losses increased to $6.0 million for
the first six months of 2005 compared to $3.8 million in the same period of
2004. At June 30, 2005, the allowance for loan losses was 1.22% of net loans.
Net chargeoffs for the first six months of 2005 were $8.4 million compared to
$3.3 million for the same period in 2004. 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 $17.6 million at June 30, 2005 is adequate. Loans
classified substandard, doubtful, or loss declined from approximately $72
million at December 31, 2004 to approximately $66 million at June 30, 2005, and
includes two credits expected to be sold in the third quarter totaling $7.4
million. The Provision for Loan Losses was increased by $1.5 million during the
quarter due primarily to additional losses relating to the recent decision to
sell certain problem loan relationships to a third party in order to mitigate
the unknown risks associated with anticipated litigation and liquidation of the
credits. The sales are expected to be completed during the third quarter. The
loan balances have already been charged down to an amount equal to the expected
net sale proceeds.

Non-performing Loans

Non-performing loans, which include the aforementioned $7.4 million in loans
anticipated to be sold, consist of (1) non-accrual 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 non-performing loans at June 30, 2005 and December 31, 2004 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.

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 of 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 regularly monitored for behavioral changes.


                                                                              11
<PAGE>
     The Corporation from time to time utilizes derivatives to manage interest
rate risk. Management regularly evaluates the merits of such interest rate risk
management products and strategies but does not anticipate the use of such
products will become a major part of the Corporation's risk management strategy.

     The table below shows the Corporation's estimated sensitivity profile as of
June 30, 2005. 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 3.98% over the next 12 months and increase
7.44% over the following 12 months. Given a 100 basis point decrease in rates,
net interest income would decrease 2.66% over the next 12 months and decrease
6.31% 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>

    Down 100                      -2.66         -6.31         -8.97
    Up 100                         3.98          7.44         10.19

</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 $12.5
million of investments that mature throughout the coming 12 months. The
Corporation also anticipates $100.6 million of principal payments from
mortgage-backed securities. Given the current rate environment, the Corporation
anticipates $14.1 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 six months of 2005 to the year 2004, average loans are
up $12.4 million. Average borrowings are down $77.2 million. Reduction in the
average investments of $84.5 million was used to fund loans and reduce
borrowings. Average shareholders' equity increased $9.8 million, or 3.7%. Strong
financial performance pushed book value per share up 4.1% to $20.04 in 2005 from
$19.25 at June 30, 2004. Book value per share is calculated by dividing the
total equity by the number of shares outstanding.

Capital Adequacy

     As of June 30, 2005, 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 well capitalized the Corporation must maintain minimum total
risk-based, Tier I risk-based and Tier I leverage ratios as set forth in the
table. There are no conditions or events since that notification that management
believes have changed the Corporation's category.
