             1ST SOURCE CORPORATION UP 85.88 PERCENT IN 2ND QUARTER,
                          INCREASED DIVIDEND ANNOUNCED


         South Bend, IN -- 1st Source Corporation (Nasdaq:SRCE), parent company
of 1st Source Bank, today reported net income of $8.72 million for the second
quarter of 2004, up 85.88 percent over the $4.69 million reported in the second
quarter of 2003. During the first six months of 2004, net income for 1st Source
Corporation was $13.80 million, a 50.79 percent increase over the $9.15 million
reported for the same period in 2003.
         Diluted net income per common share for the second quarter of 2004
amounted to $0.42, up 90.91 percent compared with $0.22 reported in the second
quarter of 2003. Diluted net income per share for the first two quarters of 2004
was $0.66, an increase of 53.49 percent over the $0.43 reported in the same
period a year ago.
          Earnings for the second quarter of 2004 represent a return on average
common shareholders' equity of 11.03 percent, as compared to 5.95 percent for

quarter of 2004 was 1.08 percent versus 0.57 percent reported in the second

reported that at the July meeting, the Board of Directors approved an increase
in the cash dividend for the second quarter to $0.11 per share from $0.10 per
share last quarter. This is a 10.00 percent increase from the previous quarter's
dividend and a 22.22 percent increase over the second quarter dividend of 2003.
The increased cash dividend is reflective of the improving performance of the
company and will be payable on August 16, 2004, to shareholders of record August

         Mr. Murphy commented, "1st Source's financial performance continues to
improve. We have worked diligently to strengthen our credit quality which has
shown steady progress over the past year. We are still affected by decreased
interest margins and volatility in the valuation of our mortgage servicing
rights portfolio, but this quarter that volatility had a positive effect."
         Murphy concluded, "We have also continued to look for opportunities to
grow our customer base and opened a new banking center on South Bend's south
side in April. We continue to review and upgrade our systems and processes to
help us provide outstanding customer service and better manage our businesses."
         1st Source's reserve for loan losses as of June 30, 2004 was 3.14
percent of total loans compared to 3.22 percent at the end of the first quarter
of 2004 and 3.01 percent for the second quarter a year ago. 1st Source's
provision for loan losses was $0.48 million this quarter compared to $4.90
million for the second quarter of 2003. Net charge-offs were $0.48 million for
the second quarter 2004 compared to $6.48 million for the second quarter of
2003. The ratio of nonperforming assets to net loans and leases was 1.22 percent
on June 30, 2004, compared to 2.65 percent on June 30, 2003.
         Tax-equivalent net interest income was $26.02 million for the second
quarter of 2004, down 5.41 percent from 2003's second quarter. The net interest
margin was 3.45 percent for the second quarter of 2004 versus 3.66 percent for
the same period in 2003. For the first six months of 2004, tax-equivalent
interest income was $52.49 million compared to $54.82 million for the first six
months of 2003, a decrease of 4.24 percent. The net interest margin was 3.49
percent for the six months ending June 30, 2004, versus 3.69 percent for the
same period in 2003.
         Noninterest income for the second quarter of 2004 was $20.22 million,
down 7.74 percent from the second quarter of 2003. In the second quarter,
equipment rental income decreased due to the shrinkage of the operating lease
portfolio, while other income decreased with the elimination of securitization
income, as 1st Source no longer securitizes any of its loan portfolio. Trading
security income also declined in the second quarter. Mortgage banking income
increased in the second quarter of 2004 compared to a year ago as mortgage
servicing

rights impairment recoveries of $3.78 million offset both a reduction in
mortgage origination volume and reduced gains on the sale of mortgage loans into
the secondary market.
         For the first six months of 2004, noninterest income was $34.24
million, down 18.39 percent from 2003. Significant items affecting comparability
between six month periods included decreased income from mortgage banking,
equipment rental, securitization and securities trading.
         Noninterest expense was $31.95 million for the second quarter of 2004,
compared with $37.28 million for the second quarter of 2003. For the first six
months, noninterest expense was $64.29 million, compared with $72.08 million for
the same period in 2003. In general, noninterest expense improvements in 2004
reflect decreases in salaries and employee benefits expense, depreciation on
leased equipment, and loan collection and repossession expenses partially offset
by an increase in professional fees which are included in other expense.
         As of June 30, 2004, the 1st Source common equity-to-assets ratio was
9.50 percent compared to 9.63 percent a year ago. Common shareholders' equity
was $314.94 million, down 0.70 percent from the $317.17 million a year ago, due
to the repurchase of 103,733 shares of common stock and a decrease of $10.51
million in accumulated other comprehensive income. The decrease in accumulated
other comprehensive income was a result of changes in unrealized gain or loss on
securities in the available-for-sale portfolio. Total assets at the end of the
second quarter of 2004 were $3.32 billion, up 0.63 percent from the same time
last year. Total deposits were down 9.79 percent and total loans were up 6.27
percent over the comparable figures at the end of the second quarter of 2003.
