              1ST SOURCE INCOME UP 36.72 PERCENT IN FIRST QUARTER,
                                DIVIDEND REPORTED

     South Bend, IN -- 1st Source Corporation (Nasdaq:  SRCE), parent company of
1st Source Bank today reported net income of $6.94 million for the first quarter
of 2005, up 36.72 percent over the $5.08 million in the first quarter of 2004.

     Diluted net income per share of common stock for the first  quarter of 2005
amounted to $0.33 compared with $0.24 for the first quarter of 2004, an increase
of 37.50 percent.  Return on average common  shareholders' equity for 1st Source
Corporation  was 8.60 percent  compared to 6.43 percent for the first quarter of
2004,  and return on average  total  assets was 0.84  percent  compared  to 0.63
percent a year ago.

     At its April meeting,  the Board of Directors approved a first quarter cash
dividend of $0.12 per common share,  an increase of 20.00 percent over the first
quarter  cash  dividend in 2004.  The cash  dividend  will be payable on May 16,
2005, to shareholders of record May 9, 2005.

     Christopher J. Murphy III, Chairman and Chief Executive Officer,  commented
on  the  first  quarter  by  saying,  "Our  credit  quality  continues  to  show
improvement and this quarter is no exception. Over the last three years, we have
taken 71 aircraft  back in  repossession,  and are pleased  that 70 of them have
been sold in an orderly manner,  leaving us with only one left for  disposition.
Interest  rate margin  compression  continues  but recent  changes in short term
rates could lead to some improvement in subsequent quarters."

     Mr.  Murphy  continued,  "This is also a time of  growth  in our  community
banking markets. We have opened three new banking centers in Northern Indiana so
far this year  including  replacement  facilities in Chesterton and on the Saint
Mary's College campus,  as well as a new in-store banking center in the Martin's
Super Market in Granger. All in all, it has been a productive first quarter."

     As of March 31, 2005, the common  equity-to-assets ratio for 1st Source was
9.78 percent, down from 9.93 percent a year ago. Common shareholders' equity was
$326.63  million,  up 2.12 percent from March 31, 2004.  At the end of the first
quarter of 2005,  total assets were $3.34  billion,  up 3.68 percent from a year
ago. Loans and leases increased 4.73 percent and deposits increased 7.74 percent
from a year ago.

     For the first  quarter of 2005,  1st Source's  provision for loan and lease
losses was $(0.42) million as compared to $0.10 million for the first quarter of
2004. Net charge-offs  were $0.60 million for the first quarter of 2005 compared
to $0.10  million in the first quarter of 2004.  The resulting  reserve for loan
and lease  losses as of March 31,  2005,  was 2.75  percent  of total  loans and
leases,   compared  to  3.22  percent  as  of  March  31,  2004.  The  ratio  of
nonperforming assets to net loans and leases was 1.10 percent on March 31, 2005,
compared to 1.45 percent for the same period last year.

     Tax-equivalent  net  interest  income  was  $24.25  million  for the  first
quarter,  down 8.39  percent  from 2004's  first  quarter,  and the net interest
margin was 3.15 percent versus 3.53 percent in the first quarter of 2004.

     Noninterest income for the first quarter 2005 was $17.70 million,  up 26.22
percent  from the first  quarter  of 2004.  The  predominant  factor  behind the
increase in 2005 was an increase in mortgage  banking  income,  primarily due to
mortgage servicing rights recovery of $1.09 million in the first quarter of 2005
versus mortgage servicing rights impairment of $3.23 million for the same period
in 2004. Other factors affecting  noninterest income include decreased equipment
rental income and increased investment security and other investment gains.

     Noninterest  expense was $31.67  million for the first quarter  2005,  down
2.07 percent from the first  quarter of 2004,  primarily  due to decreased  loan
collection and repossession  expense,  offset by increased salaries and employee
benefits and net occupancy expense.
