 FIRST FINANCIAL CORPORATION REPORTS SECOND QUARTER EARNINGS OF $.37 PER SHARE

TERRE HAUTE, INDIANA - First Financial Corporation (NASDAQ:THFF) today announced
the results for the second quarter of 2005 with net income for the three-month
period ended June 30, 2005 of $5.0 million or $.37 per share. Earnings for the
six-months ended June 30, 2005 are $11.3 million. Loans at June 30, 2005
increased $1.7 million to $1.46 billion and deposits increased $59.6 million to
$1.49 billion from the previous year quarter end.

Rising interest rates have had a positive impact on the Corporation's net
interest income, which for the first six months of 2005 increased by $935
thousand or 2.62% over the same period in 2004. The net interest margin
increased to 3.95% for the six-months ended June 30, 2005 from 3.77% for the
same period in 2004. This 4.8% increase was driven by growth in the yield on
earning assets which outpaced the average cost of funds.

The modest amount of loan growth for the year has allowed the Corporation to
direct attention to aggressively addressing some potential asset quality
concerns during the second quarter. Letters of intent to sell several
non-performing loans were entered into during the period. This has resulted in
larger than normal net charge-offs for the quarter, as these loans will be sold
at a discount. This will allow the Corporation to reinvest the proceeds into
performing assets to improve future results. A $1.5 million addition to the
allowance for loan and leases losses was made to recognize the additional losses
resulting from this decision. At period end the allowance was 1.2% of loans
outstanding.

Non-interest income for the second quarter of 2005 was $7.8 million compared to
$8.3 million for the same period in 2004. This reduction of approximately $500
thousand primarily resulted from $391 thousand less gain on the sale of
investment securities for the 3 months ended June 30, 2005 compared to the same
period of 2004. The year-to-date non-interest income is $5.4 million less than
last year's performance largely as a result of the previously reported
non-taxable gain on life insurance realized in the first quarter of 2004.

Benefits continue to be realized from the consolidation of affiliate banks into
one bank as second quarter non-interest expense was lower than the same period
in 2004. Non-interest expense for the second quarter and the six-months ended
June 30, 2005 is $95 thousand and $286 thousand less, respectively, than the
same periods in 2004. Seven of the eight subsidiary banks have completed the
consolidation process and now operate as First Financial Bank.



A $59.6 million or 4.2% increase in deposits from June 30, 2004 to June 30, 2005
was used to fund loans and reduce borrowings. Average assets decreased $70.7
million, or 3.19%. The decrease primarily resulted from the Corporation's use of
maturing investments to retire debt. Shareholder's equity increased $8.7
million, or 3.3%, and book value per share rose by $.79 to $20.04, or 4.1%.

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. in Indiana; and First Community Bank NA in Illinois.
