                           FIRST FINANCIAL CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     The accompanying June 30, 2006 and 2005 consolidated financial statements
are unaudited. The December 31, 2005 consolidated financial statements are as
reported in the First Financial Corporation (the "Corporation") 2005 annual
report. The information presented does not include all information and footnotes
required by U.S. generally accepted accounting procedures for complete financial
statements. The following notes should be read together with notes to the
consolidated financial statements included in the 2005 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. Some items in the prior
year financials were reclassified to conform to the current presentation.

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:

   calculated under SFAS No. 114                            $1,898       $3,622

     Interest payments on impaired loans are typically applied to principal
unless collection of the principal amount is deemed to be fully assured, in
which case interest is recognized on a cash basis.

7. Recent Accounting Pronouncements

     FASB Interpretation No. 48 - In June 2006, the Financial Accounting
Standards Board (FASB) issued FASB Interpretation No. 48, "Accounting for
Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109" (FIN
48), which prescribes a recognition threshold and measurement attribute for the
financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. FIN 48 also provides guidance on
derecognition, classification, interest and penalties, accounting in interim
periods, disclosure and transition. FIN 48 is effective for fiscal years
beginning after December 15, 2006. We are still evaluating the impact, if any,
the adoption of FIN 48 will have on our financial statements.

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
three 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 2005.

     This Quarterly Report on Form 10-Q contains forward-looking statements.
Forward-looking statements provide current expectations or forecasts of future
events and are not guarantees of future performance, nor should they be relied
upon as representing management's views as of any subsequent date. The
forward-looking statements are based on management's expectations and are
subject to a number of risks and uncertainties. Although management believes
that the expectations reflected in such forward-looking statements are
reasonable, actual results may differ materially from those expressed or implied
in such statements. Risks and uncertainties that could cause actual results to
differ materially include, without limitation, the Corporation's ability to
effectively execute its business plans; changes in general economic and
financial market conditions; changes in interest rates; changes in the
competitive environment; continuing consolidation in the financial services
industry; new litigation or changes in existing litigation; losses, customer
bankruptcy, claims and assessments; changes in banking regulations or other
regulatory or


                                                                               9


legislative requirements affecting the Corporation's business; and changes in
accounting policies or procedures as may be required by the Financial Accounting
Standards Board or other regulatory agencies. Additional information concerning
factors that could cause actual results to differ materially from those
expressed or implied in the forward-looking statements is available in the
Corporation's Annual Report on Form 10-K for the year ended December 31, 2005,
and subsequent filings with the United States Securities and Exchange Commission
(SEC). Copies of these filings are available at no cost on the SEC's Web site at
www.sec.gov or on the Corporation's Web site at www.first-online.com. Management
may elect to update forward-looking statements at some future point; however, it
specifically disclaims any obligation to do so.

                          Critical Accounting Policies

     Certain of the Corporation's accounting policies are important to the
portrayal of the Corporation's financial condition and results of operations,
since they require management to make difficult, complex or subjective
judgments, some of which may relate to matters that are inherently uncertain.
Estimates associated with these policies are susceptible to material changes as
a result of changes in facts and circumstances. Facts and circumstances which
could affect these judgments include, but without limitation, changes in
interest rates, in the performance of the economy or in the financial condition
of borrowers. Management believes that its critical accounting policies include
determining the allowance for loan losses and the valuation of goodwill. See
further discussion of these critical accounting policies in the 2005 Annual
Report on Form 10-K.

                          Summary of Operating Results

     Net income for the three months ended June 30, 2006 was $6.4 million
compared to $5.0 million in the same period in 2005. Basic earnings per share
increased to $0.48 for the second quarter of 2006 compared to $0.37 for 2005, a
29.7% increase.

     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 to $36.9 million in the first six months of 2006 from $36.6 million in
the same period in 2005, a 0.8% increase. The net interest margin decreased to
3.92% in 2006 from 3.95% in 2005, a 0.8% decrease, driven by an increase in the
proportion interest-earning assets in the investment portfolio compared to the
loan portfolio. Investments provide a lower level of risk and with that a lower
return.

Non-Interest Income

     Non-interest income for the quarter was $7.2 million. The strategy of
holding more mortgage loans in the portfolio has the effect of reducing
non-interest income as loan fees are deferred. This was the primary difference
between these results and the $7.8 million of non-interest income for the same
period in 2005 when loans were being sold which requires immediate recognition
of fees into income. Deposit fee income, however increased due to the higher
level of deposits in 2006.

Non-Interest Expenses

     The Corporation's non-interest expense for the quarter ended June 30, 2006
compared to the same period in 2005 increased by $434 thousand or 2.7%.
Equipment expenses and personnel costs were higher during the second quarter of
2006 compared to the same period of 2005. Cost increases included merit
increases in salaries and higher benefit costs, as well as the new banking
center in Vincennes, Indiana opened early in 2006. The effective tax rate for
2006 has increased to 26.6% compared to 24.8% for 2005.

Provision for Loan Losses

     The Corporation's provision for loan losses decreased $3.1 million for the
second quarter of 2006 compared to the same period of 2005. Net charge-offs for
the three months ended June 30, 2006 were $1.3 million compared to $6.1 million
for the same period in 2005.

Non-performing Loans

     Non-performing loans 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, 2006 and December 31, 2005 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 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
June 30, 2006. 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 decrease .79% over the next 12 months and increase
..71% over the following 12 months. Given a 100 basis point decrease in rates,
net interest income would decrease 2.17% over the next 12 months and decrease
4.18% over the following 12 months. These estimates assume all rate changes
occur overnight and management takes no action as a result of this change.


                                                                              11





                            Percentage Change in Net
                                Interest Income
Basis Point            ---------------------------------
Interest Rate Change   12 months   24 months   36 months
--------------------   ---------   ---------   ---------
                                      
Down 200                 -4.95       -9.20       -13.81
Down 100                 -2.17       -4.18        -6.55
Up 100                    -.79         .71         3.45
Up 200                   -2.58        -.25         4.99


     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 $12.8
million of investments that mature throughout the coming 12 months. The
Corporation also anticipates $62.3 million of principal payments from
mortgage-backed securities. Given the current rate environment, the Corporation
anticipates $12.4 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 2006 to the same period of 2005, average
loans are down $67.5 million. Average deposits are up $28.5 million. Average
investments increased $79.8 million. Average borrowings decreased $28.6 million.
The average allowance for loan and lease losses declined from 1.36% at June 30,
2005 to 1.23% at June 30, 2006. A reduction in classified assets, lower net
charge-offs and improved overall credit quality allowed the Corporation to
reduce its allowance percentage of loans outstanding.

Capital Adequacy

     As of June 30, 2006, the most recent notification from the respective
regulatory agencies categorized the subsidiary banks as well capitalized under
the regulatory framework for prompt corrective action regulations. To be
categorized as well capitalized the banks 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 bank's category.
