  FIRST FINANCIAL CORPORATION REPORTS FIRST QUARTER EARNINGS OF $.48 PER SHARE

TERRE HAUTE, INDIANA -- First Financial Corporation (NASDAQ: THFF) today
announced first quarter results reflecting year-to-date net income of $6.3
million, or $.48 per share. During this period the Corporation's loan volume
increased to $1.45 billion compared to $1.43 billion at March 31, 2004. Deposits
rose to $1.47 billion from $1.43 billion for the same period in 2004.

The Corporation has continued to realize cost savings from consolidating our
affiliated banks into one bank. Non-interest expense for the first quarter of
2005 was reduced by $191,000 or 1.23% compared to the first quarter of 2004. Of
the eight subsidiary banks to be consolidated, seven have completed the
consolidation process and operate as a part of First Financial Bank.

Rising interest rates have had a positive impact on the Corporation's net
interest income, which for the first quarter of 2005 increased by $358,000 or
1.99% over the same period in 2004. The net interest margin increased to 3.92%
at March 31, 2005 from 3.78% for the first quarter in 2004. This 3.8% increase
was driven by growth in yields on earning assets that outpaced the average cost
of funds.

Comparing the first quarter of 2005 to 2004, deposits were up $34.0 million, or
2.37%. These deposits were used to fund an increase in loans of $15.4 million,
or 1.07%. Average assets decreased $85.7 million, or 3.82%, as the Corporation
used maturing investments to retire debt. Shareholders' equity increased $4.0
million, or 1.52%, and book value per share rose by $.35 to $20.02, or 1.78%.

In the first quarter of 2005 non-interest income declined by $4.8 million
compared to the same period in 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. Non-interest income was also impacted by rising interest
rates, which reduced the demand for fixed-rate mortgage loans. The Corporation's
gain on the sale of mortgage loans in the first quarter of 2005 decreased by
$224,000 compared to the same period in 2004 due to fewer loans being available
for sale.

The Corporation increased its provision for loan losses to $2.2 million for the
first quarter of 2005 compared to $1.9 million for first quarter of 2004. Net
charge-offs year-to-date for 2005 were $2.1 million compared to $1.8 million for
the same period in 2004. The Corporation made this increase in part due to
perceived uncertainties as to the direction of the U.S. economy, including
stagnant earnings in the corporate sector and a rise in the rate of inflation.

First Financial Corporation continues to focus on careful cost control,
proactive risk management, effective corporate governance and adherence to
internal controls and routines.

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.
