               1ST SOURCE CORPORATION ANNOUNCES YEAR END RESULTS,
                               INCREASED DIVIDEND

        South Bend, IN--1st Source Corporation (Nasdaq:SRCE), parent company of
1st Source Bank, today reported net income of $24.97 million for the year 2004,
an increase of 30.34 percent over the $19.15 million reported for the year
2003. Diluted net income per common share for 2004 amounted to $1.19, up 30.77
percent compared to $0.91 diluted net income per common share for 2003.

        Net income was $7.86 million for the fourth quarter of 2004, up 46.61
percent compared to the $5.36 million of net income reported for the fourth
quarter of 2003. Diluted net income per common share for the fourth quarter of
2004 amounted to $0.37, compared to $0.26 per common share reported in the
fourth quarter of 2003.

        The Board of Directors approved an increase in the fourth quarter cash
dividend to $0.12 per share. The cash dividend is payable on February 14, 2005
to shareholders of record on February 7, 2005, and is an increase of 20.00
percent over the fourth quarter cash dividend in 2003.

        Christopher J. Murphy III, Chairman of 1st Source Corporation,
commented, "I am very pleased with the continued improvement in 1st Source's
performance - especially credit quality. In the fourth quarter, there was a
recovery of the provision for loan losses of $0.59 million compared to a charge
of $2.83 million to the provision for loan losses in the fourth quarter of 2003.
The volatility experienced all year in the value of mortgage servicing rights
continued in the fourth quarter, fortunately, the quarter included a recovery of
prior impairments of $2.23 million. This was offset slightly by an additional
impairment charge of $0.91 million on FHLMC (Freddie Mac) and FNMA (Fannie Mae)
preferred stocks, which we first reported on last quarter."

        "As compared to prior quarters, the size of the bank increased by over
$170 million in the fourth quarter due to significant growth in public tax funds
collected and deposited with us for late November and all of December. This
year's collection and disbursement activities were different from prior years
with the full year's property tax receipts for several Indiana counties being
deposited with us at the close of the year. Due to the short term nature of
these funds and our long term arrangements with local governments, there was a
negative spread on these funds for November and December. These funds were
disbursed by early January."

        Mr. Murphy concluded, "The consumer banking, personal asset management,
insurance and the specialty finance areas all had a productive quarter. We are
pleased with the overall results of the fourth quarter and look forward to
2005."

        1st Source's reserve for loan losses as of December 31, 2004, was 2.79
percent of total loans and leases, compared to 3.14 percent as of December 31,
2003. Net charge-offs were $3.93 million for the fourth quarter 2004, compared
to $2.83 million a year ago. Net charge-offs for the year were $6.60 million
compared to $13.36 million in 2003. The ratio of nonperforming assets to net
loans and leases was 1.42 percent on December 31, 2004, compared to 1.59
percent on December 31, 2003.

        Noninterest income for the fourth quarter of 2004 was $18.09 million,
down 6.70 percent from the fourth quarter of 2003. This decrease was due to a
reduction in equipment rental income offset by an increase in mortgage banking
income. For the year, noninterest income was $62.73 million, down 21.78 percent
from 2003. The predominant factor behind the decline in 2004 was mortgage
banking income and equipment rental income.

        Noninterest expense was $30.43 million for the fourth quarter of 2004,
down 10.82 percent from the fourth quarter of 2003. For the year, noninterest
expense was $127.09 million, down 8.50 percent from 2003. The reduction in
noninterest expense was primarily due to decreased salaries and employee
benefits, leased equipment depreciation and loan collection and repossession
expense, which were partially offset by an increase in professional fees.

        As of December 31, 2004, the 1st Source common equity-to-assets ratio
was 9.16 percent, compared to 9.45 percent a year ago. Shareholders' equity was
$326.60 million, up from $314.69

million a year ago. Total assets at the end of 2004 were $3.56 billion, up 7.01
