                 THIRD QUARTER EARNINGS, CASH DIVIDEND ANNOUNCED
                           FOR 1ST SOURCE CORPORATION


     South Bend, IN -- 1st Source Corporation (Nasdaq:SRCE), parent company of
1st Source Bank, today reported net income of $4.64 million for the third
quarter of 2003, a 120.99 percent increase over the $2.10 million for the third
quarter of 2002. During the first nine months of 2003, net income for 1st Source
Corporation was $13.79 million, up 51.97 percent over the $9.08 million reported
for the same period in 2002.

     Diluted net income per common share for the third quarter of 2003 amounted
to $0.22, up 120.00 percent compared to $0.10 for the third quarter of 2002.
Diluted net income per common share for the first three quarters of 2003 was
$0.65 versus $0.43, an increase of 51.16 percent over the same period a year
ago.

     Earnings for the third quarter of 2003 represent a return on average common
shareholders' equity of 5.83 percent, compared to 2.68 percent for the third
quarter of 2002. Return on average total assets for the third quarter of 2003
was 0.56 percent, compared to 0.25 percent for the third quarter of 2002.

     Christopher J. Murphy III, Chairman and Chief Executive Officer, reported
that at its October meeting, the Board of Directors approved a cash dividend
increase for the third quarter to $0.10 per share. The cash dividend will be
payable on November 17, 2003 to shareholders of record on November 10, 2003. The
cash dividend is an 11.11 percent increase over the third quarter cash dividend
in 2002.

     Mr. Murphy commented, "While we are pleased with the improvement in our
earnings and credit quality for the quarter over last year, we are still quite
cautious about the future. Interest rate margins have tightened and loan growth
is almost non-existent. This has permitted us to allow wholesale funding to
mature and roll off. As a result, we have very strong liquidity and rely on
almost no brokered CDs, public funds, or other wholesale funding. Today,
virtually everything on our balance sheet in the deposit or funding categories
is essentially core funding. On the credit side, we have seen improvements in
the market for used aircraft, and cash flows have improved somewhat for many of
our equipment customers. For the quarter, our charge-offs and provisions were
down significantly and our ratio of nonperforming assets to net loans and leases
improved nicely."

                                       1


     Mr. Murphy continued, "Our branches are performing well, and based on
recent market studies, we continue to enjoy dominant market deposit share in our
15 county area. Also, recently released government data highlights our continued
strength in the small business, home improvement and mortgage financing sectors
of our market. One of the most exciting things for us this past quarter was the
introduction of InfoSource Online, our free online service for personal checking
account customers. The overwhelmingly positive response of our customers to the
new service reinforces our strategy of keeping our customers' best interests in
mind and providing straight talk and sound advice."

     The provision for loan losses was $4.08 million in the third quarter of
2003 compared to $8.77 million in the third quarter of 2002. 1st Source's
reserve for loan losses as of September 30, 2003 was 3.13 percent of total
loans, compared to 2.60 percent as of September 30, 2002. Net charge-offs were
$4.05 million for the third quarter 2003, compared to $7.24 million in the same
quarter last year. The ratio of nonperforming assets to net loans and leases was
2.20 percent on September 30, 2003 compared to 3.44 percent on September 30,
2002.

     Noninterest income for the third quarter of 2003 was $18.85 million, up
20.79 percent from the third quarter of 2002. For the first nine months of 2003,
noninterest income was $60.81 million, up 16.42 percent from 2002. The
predominant factor behind the growth in 2003 was mortgage loan servicing and
sale income, which reached near record levels in the first nine months of 2003.
This increase was partially offset by a decrease in equipment rental income and
the recording of $2.74 million of securitization impairment. The majority of
this impairment is due to a change during the quarter in assumptions concerning
the timing of future cash flows from the 1998 1st Source Master Trust
Securitization to 1st Source Bank, as recorded under SFAS 140, Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of Liabilities.

     Noninterest expense was $32.70 million for the third quarter, compared to
$33.51 million for the third quarter of 2002. For the first nine months,
noninterest expense was $104.78 million, compared to $99.42 million for the same
period in 2002. In general, year to date 2003 noninterest expense reflects
higher personnel expense and an increase in expenses related to loan collection
and repossessions.

     As of September 30, 2003, the 1st Source common equity-to-assets ratio was
9.95 percent compared to 9.08 percent a year ago. Common shareholders' equity
was $318.87 million, up 2.53 percent from the $310.99 million reported a year
ago. Total assets at the end of the third quarter of 2003 were $3.21 billion,
down 6.36 percent from the same time last year. Total deposits were down 9.72
percent while total loans were down 10.72 percent over the comparable figures at
the end of the third quarter of 2002.
