              FIRST FINANCIAL CORPORATION REPORTS EARNINGS INCREASE

     First Financial Corporation (NASDAQ:THFF) today announced a 28.7% increase
in net income for the three months ending June 30, 2006 over the same period of
2005. Net income was $6.4 million or $.48 per average share compared to $5.0
million or $.37 per average share for the second quarter of 2005. This
performance brings the year-to-date earnings to $11.9 million or $.90 per
average share compared to $11.3 million or $.84 per average share reported for
the six months ended June 30, 2005.

     During the quarter net interest income improved to $18.5 million compared
to $18.3 million for the same period a year ago. The Corporation's improved
asset quality, evidenced by a 15% reduction in classified assets at June 30,
2006 as compared to June 30, 2005, resulted in a reduction of the provision for
loan losses of $3.1 million compared to the prior year quarter. Due to a higher
interest rate environment, the Corporation has chosen to retain mortgage loans
in the portfolio during 2006. This has resulted in $413 thousand less income
from gains on the sale of loans during the second quarter of 2006 compared to
the second quarter of 2005. Total non-interest income of $7.2 million for this



period was $592 thousand less than 2005. Non-interest expenses for the second
quarter increased by $434 thousand or 2.7% over the same period of 2005. A new
banking center facility in Vincennes, Indiana which opened early in 2006,
accounted for 36% or $156 thousand of this increase.

     During the quarter deposits of the Corporation increased $9.9 million from
the same period in 2005. While loans have decreased during this period $75
million or 5.1% as a result of reducing classified assets and improving asset
quality, loans have increased from the first quarter of this year by $4.1
million and total assets increased by $22.1 million for the same period. For the
18th consecutive year the Corporation increased dividends to the shareholders.
The dividend of $.42 per share was declared during the second quarter and
reduced shareholders' equity $5.7 million.

     First Financial Corporation is the holding company for First Financial Bank
NA in Indiana and Illinois, The Morris Plan Company of Terre Haute and Forrest
Sherer Inc.
