         1ST SOURCE  INCOME UP 13.88 PERCENT IN FIRST QUARTER,
                                    DIVIDEND REPORTED

     South Bend, IN -- 1st Source Corporation (Nasdaq: SRCE), parent company of
1st Source Bank, today reported net income of $5.08 million for the first
quarter of 2004, up 13.88 percent over the $4.46 million in the first quarter of
2003.

     Diluted net income per share of common stock for the first quarter of
2004 amounted to $0.24 compared with $0.21 for the first quarter of 2003, an
increase of 14.29 percent. Return on average common shareholders' equity for 1st
Source Corporation was 6.43 percent compared to 5.80 percent for the first
quarter of 2003, and return on average total assets was 0.63 percent compared to
0.55 percent a year ago.

     At their April meeting, the Board of Directors approved a first quarter
cash dividend of $0.10 per common share. The cash dividend will be payable on
May 17, 2004, to shareholders of record May 10, 2004, and is an increase of
11.11 percent over the first quarter cash dividend in 2003.

     Christopher J. Murphy III, Chairman and Chief Executive Officer,
commented on the first quarter by saying, "We are pleased with the gradual
improvement in our earnings and are particularly gratified by the improvement in
our nonperforming assets. We have spent the last year and a half working through
the collection and sale of both aircraft and automobiles from troubled
customers. While we have not completed all reconditioning and sale of our
nonperforming assets, the markets have stabilized and we see some improvement
among customers

in the air cargo and aircraft sales businesses as well as with our rental car
customers. Margins remain tight and we continue to see significant volatility in
the valuation of our mortgage servicing rights due to the variability of
historically low mortgage rates and the resulting high mortgage refinance
volumes," Murphy concluded.

     As of March 31, 2004, the common equity-to-assets ratio for 1st Source
was 9.93 percent, up from 9.57 percent a year ago. Common shareholders' equity
was $319.86 million, up 2.02 percent from March 31, 2003. At the end of the
first quarter of 2004, total assets were $3.22 billion, down 1.62 percent from a
year ago. Loans increased 2.80 percent and deposits decreased 7.43 percent from
a year ago.

     For the first quarter of 2004, 1st Source's provision for loan losses
was $0.10 million as compared to $5.55 million for the first quarter of 2003.
Net charge-offs were $0.10 million for the first quarter of 2004 compared to
$2.93 million in the first quarter of 2003. The resulting reserve for loan
losses as of March 31, 2004, was 3.22 percent of total loans, compared to 2.92
percent as of March 31, 2003. The ratio of nonperforming assets to net loans and
leases was 1.45 percent on March 31, 2004, compared to 3.13 percent for the same
period last year.

     Tax-equivalent net interest income was $26.48 million for the first
quarter, down 3.06 percent from 2003's first quarter, and the net interest
margin was 3.53 percent versus 3.72 percent in the first quarter of 2003.

     Noninterest income for the first quarter 2004 was $14.02 million, down
30.04 percent from the first quarter of 2003. The predominant factor behind the
decrease was a reduction of loan servicing and sale income. Loan servicing and
sale income decreased due to a reduction in mortgage origination volumes,
decreased gains on sales of mortgage loans into the secondary market and
increased mortgage servicing rights impairment. Mortgage servicing rights
impairment was $3.23 million in the first quarter of 2004 versus $1.78 million
for the same period in 2003.

     Noninterest expense was $32.34 million for the first quarter 2004, down
7.07 percent from the first quarter of 2003, primarily due to decreased salaries
and employee benefits, and decreased loan collection and repossession expense,
which were offset by increased professional fees.

     Salaries and employee benefits decreased mainly because of the
capitalization of $1.26 million in salaries and benefits in connection with the
deferral of loan origination costs in the first quarter of 2004 and decreased
mortgage commissions. These decreases were partially offset by higher executive
incentive accruals and increased group insurance costs.

     Loan collection and repossession expense decreased as valuation
adjustments and other expenses related to repossessed assets decreased.
