                1ST SOURCE CORPORATION ANNOUNCES YEAR END RESULTS

         South Bend, IN--1st Source Corporation (Nasdaq:SRCE), parent company of
 1st Source Bank, today reported net income of $19.15 million for the year 2003,
 an increase of 90.80 percent over the $10.04 million reported for the year
 2002. Diluted net income per common share for 2003 amounted to $0.91, up 93.62
 percent compared to $0.47 diluted net income per common share for 2002.

         Net income was $5.36 million for the fourth quarter of 2003 compared to
 the $0.96 million of net income reported for the fourth quarter of 2002.
 Diluted net income per common share for the fourth quarter of 2003 amounted to
 $0.26, compared to $0.05 per common share reported in the fourth quarter of
 2002.

         The Board of Directors approved a fourth quarter cash dividend of $0.10
 per share. The cash dividend is payable on February 17, 2004 to shareholders of
 record on February 9, 2004, and is an increase of 11.11 percent over the fourth
 quarter cash dividend in 2002.

         Christopher J. Murphy III, Chairman of 1st Source Corporation,
 commented, "While the fourth quarter presented challenges to our margins, we
 were pleased with the improvements in the quality of our loan portfolios as
 evidenced by lower non-performing asset ratios and lower net charge offs than a
 year ago."

          Mr. Murphy continued, "At the end of the quarter, we closed down the
 asset securitization and purchased the loans in the 1st Source Master Trust.
 For many years, 1st Source was the originator and servicer of loans sold to and
 owned by the Trust, which were mainly loans secured by business use and
 personal aircraft, or by car rental company vehicles. However, the Trust had
 outlived its usefulness as a source of funding, and its accounting and
 reporting requirements had become way too time consuming. Closing the Trust
 freed up intellectual capital which can be redirected to achieve better benefit
 for 1st Source."

         "We are also very pleased with the success of our new personal on-line
 banking product, InfoSource Online, which provides free basic home banking
 services to our customers. Introduced late in the third quarter, over 11,000
 customers had decided to become active users by year end, which is a pretty
 sound endorsement of the product, " Mr. Murphy concluded.

         The provision for loan losses was $2.83 million in the fourth quarter
 compared to $8.33 million in the fourth quarter of 2002. 1st Source's reserve
 for loan losses as of December 31, 2003, was 3.14 percent of total loans,
 compared to 2.72 percent as of December 31, 2002. Net charge-offs were $2.83
 million for the fourth quarter 2003, compared to $8.06 million a year ago. Net
 charge-offs for the year were $13.36 million compared to $38.06 million in
 2002. The ratio of nonperforming assets to net loans and leases was 1.59
 percent on December 31, 2003, compared to 2.79 percent on December 31, 2002.

         Noninterest income for the fourth quarter of 2003 was $19.39 million,
 down 7.18 percent from the fourth quarter of 2002. This decrease was due to the
 slowdown of mortgage loan refinancings, lower trading account securities gains,
 and lower securitization impairment in the fourth quarter of 2003 compared to
 the same period in 2002. For the year, noninterest income was $80.20 million,
 up 9.68 percent from 2002. The predominant factor behind the growth in 2003 was
 mortgage loan servicing and sale income. This increase was partially offset by
 a decrease in equipment rental income and increased securitization impairment
 charges.

Noninterest expense was $34.12 million for the fourth quarter of 2003, down
17.42 percent from the fourth quarter of 2002. This quarter to quarter decrease
was primarily due to decreased loan collection and repossession expense,
including lower valuation adjustments on repossessed aircraft. Also,
depreciation on leased equipment decreased due to reduced demand for equipment
leases, and salaries and employee benefits decreased due to lower mortgage
commissions as mortgage loan refinancings slowed. For the year, noninterest
expense was $138.90 million, down 1.31 percent from 2002. In general, 2003
noninterest expense reflects decreased depreciation on equipment owned under
operating leases and decreased loan collection and repossession expense offset
by increased salary and employee benefit expense.

         The 2003 earnings represent a return on average shareholders' equity of
 6.12 percent, compared to 3.23 percent for 2002. Return on total assets was
 0.59 percent compared to 0.29 percent for 2002.

         As of December 31, 2003, the 1st Source common equity-to-assets ratio
 was 9.45 percent, compared to 9.08 percent a year ago. Shareholders' equity was
 $314.70 million, up 1.70 percent from $309.43 million a year ago. Total assets
 at the end of 2003 were $3.33 billion compared to $3.41 billion at the end of
 2002. Total deposits were $2.49 billion, down 8.32 percent from the end of
 2002, and total loans were $2.23 billion, up 2.37 percent from 2002.
