                 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 $3.31 million for the third
quarter of 2004, a 28.75 percent decrease over the $4.64 million for the third
quarter of 2003. Diluted net income per common share for the third quarter of
2004 amounted to $0.16, down 27.27 percent compared to $0.22 for the third
quarter of 2003. Overall, the Bank's underlying core businesses remained stable.
The third quarter, however, was impacted by a write-down of Federal Home Loan
Mortgage Corporation (FHLMC) and Federal National Mortgage Association (FNMA)
preferred stocks in the investment portfolio and by continued volatility in the
value of mortgage servicing rights.

         For the first nine months of 2004, net income was $17.11 million, up
24.01 percent over the $13.79 million reported for the same period in 2003,
while diluted net income per common share for the first three quarters of 2004
was up 26.15 percent over the same period a year ago to $0.82 compared to $0.65
in 2003.

         Christopher J. Murphy III, Chairman and Chief Executive Officer,
reported that at its October meeting, the Board of Directors approved a cash
dividend for the third quarter of $0.11 per share. The cash dividend will be
payable on November 15, 2004 to shareholders of record on November 8, 2004. The
cash dividend is a 10.00 percent increase over the third quarter cash dividend
in 2003.

         "While we are pleased with the fact that our year-to-date earnings are
up by 24 percent over the prior year, we are not pleased with the volatility of
the earnings," Mr. Murphy commented. "This was particularly evident when we made
the decision to recognize through the income statement the impairment of $3.67
million related to our holdings of FHLMC and FNMA preferred stock. Gains and
losses on these securities had previously been recognized in the equity section
of the balance sheet. Due to a number of factors, including recent public
disclosures about these companies and our cost in relation to their market
value, we concluded the securities were impaired and reflected the loss in our
income statement. We continue to hold these securities due to their positive
income characteristics."

         Mr. Murphy continued, "We also recognized further impairment in the
value of our mortgage servicing rights due to decreasing long term interest
rates at the close of the quarter. This caused a charge of $2.51 million,
pre-tax for the quarter compared to a recovery of $2.82 million in the same
quarter a year ago. We continue to look for ways to reduce the volatility. In
addition, we are encouraged by the improvements in our net charge-offs and
nonperforming assets compared to a year ago."

         Noninterest income for the third quarter of 2004 was $10.41 million,
down 44.81 percent from the third quarter of 2003. For the first nine months of
2004, noninterest income was $44.65 million, down 26.58 percent from 2003. Third
quarter charges to income, the impairments mentioned above, coupled with a
reduction in loan servicing and sale income and decreased equipment leasing
income were the predominant factors in the decline of noninterest income.

           As announced earlier in the quarter, 1st Source decided to redeem
$27.5 million in 9.00 percent trust preferred securities, which resulted in the
pre-tax write-off of capitalized debt issuance costs of $0.75 million and the
issuance of $30.00 million in 7.66 percent per annum fixed rate trust preferred
securities. In addition, 1st Source recognized a $1.54 million tax benefit
related to dividend received deductions claimed for the period starting in 2000
through third quarter 2004.

         Noninterest expense was down slightly for the quarter, while for the
first nine months, noninterest expense was $96.66 million, compared to $104.78
million for the same period in 2003. In general, the reduction in year-over-year
noninterest expense was primarily attributable to decreased salaries and
employee benefits, leased equipment depreciation, and loan collection and
repossession expense, which were slightly offset by an increase in professional
fees and the write-off of capitalized issuance costs of trust preferred
securities.

         The provision for loan losses was $0.24 million in the third quarter of
2004 compared to $4.08 million in the third quarter of 2003. 1st Source's
reserve for loan losses as of September 30, 2004, was $68.19 million or 3.00
percent of total loans compared to $70.05 million or 3.14 percent at the end of
the second quarter, 2004 and $63.22 million or 3.13 percent at the end of the
third quarter a year ago.

         Net charge-offs were $2.09 million for the third quarter 2004, compared
to $4.05 million in the same quarter last year. The ratio of nonperforming
assets to net loans and leases continued to improve and was 1.55 percent on
September 30, 2004, compared to 2.18 percent on September 30, 2003.

         As of September 30, 2004, the 1st Source common equity-to-assets ratio
was 9.53 percent compared to 9.76 percent a year ago. Common shareholders'
equity was $323.06 million, up 3.22 percent from the $312.97 million reported a
year ago. Total assets at the end of the third quarter of 2004 were $3.39
billion, up 5.75 percent from the same time last year. Total loans were up 12.60
percent while total deposits were down 1.56 percent over the comparable figures
at the end of the third quarter of 2003.
