                    MAINSOURCE FINANCIAL GROUP-NASDAQ, MSFG -
                  Announces Earnings for the First Quarter 2004


o        Net Income Up 3.7%

o        Earnings Per Share Up 3.0%

o        Return on Average Equity of 13.60%

o        Return on Average Assets of 1.03%

o        Net Interest Margin of 3.68%


James L. Saner, Sr., President & CEO of MainSource Financial Group, Inc.
(NASDAQ: MSFG), announced today the unaudited results for the first quarter
ended March 31, 2004. Total net income for the first quarter was $3,635,000
compared to $3,505,000 for the same period in 2003, an increase of 3.7%. The
Company reported earnings per share of $0.34, which represents a 3.0% increase
over the $0.33 per share reported in the first quarter of 2003.

Key measures of the financial performance of the Company are return on average
shareholders' equity and return on average assets. Return on average
shareholders' equity was 13.60% for the first quarter of 2004 and return on
average assets was 1.03%.

Mr. Saner stated, "I am pleased that our net interest margin has stabilized. It
improved four basis points from the fourth quarter of 2003 and seven basis
points compared to the third quarter of last year. I believe we are
well-positioned to benefit as the economic recovery accelerates and loan demand
increases."

NET INTEREST INCOME

Net interest income was $11.5 million for the first quarter of 2004, which
represents an increase of 7.1% versus the first quarter of 2003. Average earning
assets increased 12.7% while net interest margin, on a fully-taxable equivalent
basis, was 3.68% for the first quarter of 2004 compared to 3.90% for the same
period a year ago.

NON-INTEREST INCOME

Non-interest income was $4.8 million for the first quarter of 2004, unchanged
compared to the same period a year ago. The impact of the acquisition of First
Community in the second quarter of 2003 and the implementation of a formalized
overdraft program were offset by decreases in mortgage banking activity and
investment securities gains.

NON-INTEREST EXPENSE

Non-interest expense for the first quarter of 2004 was $11.1 million compared to
$10.3 million for the first quarter of 2003. The increase was due primarily to
the acquisition of First Community, which added approximately $1.5 million in
non-interest expense. Offsetting this increase was a decrease in the
amortization of deferred debt acquisition costs.



In the first quarter of 2003, the Company redeemed a portion of its subordinated
debentures and wrote-off approximately $850,000 in related costs.

ASSET QUALITY

Non-performing assets totaled $16.1 million, or 1.13% of total assets, as of
March 31, 2004 compared to $11.8 million, or 0.94% of total assets, as of the
same period a year ago. This represents a decrease from year-end 2003 of $1.2
million, or 7% of total non-performing assets. With the acquisition of First
Community, the Company added approximately $4.4 million of non-performing
assets. Management believes that adequate allowance allocations have been
provided for these loans as of March 31, 2004.

Mr. Saner stated, "We continue to emphasize the reduction of non-performing
assets. Approximately $9 million, or 56% of total non-performing assets, is
collateralized by residential real estate, which have historically had lower
levels of charge-offs. The remainder of our non-performing assets is made up of
relatively small commercial loans predominantly collateralized by real estate.
Thus, we anticipate no major losses in this category as well. We continually
monitor and analyze our allowance for loan losses and believe it is adequate."
The allowance for loan losses was $11.3 million as of March 31, 2004 and
represented 1.35% of total outstanding loans.

Mr. Saner added, "We are pleased to see other areas of our Company performing
well such as our insurance division where revenues are up almost 20% over last
year and our wealth management and investment services division continues to
grow each quarter."
