              1ST SOURCE BANK PURCHASES SECURITIZED LOAN PORTFOLIO


         South Bend, IN -- 1st Source Bank, a subsidiary of 1st Source
Corporation (SRCE), today reported the purchase of its securitized loan
portfolio for $227 million. For many years, 1st Source was the originator and
servicer of loans sold to and owned by the 1st Source Master Trust. The loans
were secured by business or personal use aircraft or by car rental company
vehicles, two of 1st Source's longstanding specialty finance product lines. The
loans served as collateral for note certificates issued by the Master Trust and
purchased by institutional investors.
         Chairman and CEO Christopher J. Murphy III commented on the
transaction, "Our securitization program has been a wonderful alternative source
for funding the growth of several of our lending businesses for many years.
However, with the growth in our core deposit base over the past few years
coupled with soft loan demand, our need for other sources of funding has
decreased. At the same time, the cost of maintaining an off-balance sheet
funding vehicle had begun to exceed its value. We have opted for simplification
and maximum transparency by purchasing the portfolio of aircraft and auto loans
we originated, have always serviced, and know very well. The purchase of these
loans will allow us to manage our customer relationships much more efficiently
and more effectively."
         At one time, the Master Trust owned $400 million in aircraft and auto
rental loans. However, as previously reported, because of increased costs, the
growing complexity of managing off-balance sheet entities, and reduced loan
demand, 1st Source stopped selling new loans to the Master Trust during the
first quarter 2003, and in May, 2003, with the agreement of all interested
parties, began a wind down of the Master Trust. As also previously reported, the
credit insurer of the certificates issued by the Master Trust questioned the
manner in which the Bank had handled certain loans in the portfolio and notified
the trustee to retain excess cash in the Master Trust reserve account pending a
response from 1st Source. 1st Source arranged for a detailed audit by a major
independent accounting firm, the results of which verified that the Bank had
handled the loans in accordance with the agreements governing the Master Trust
and consistent with industry standards.
         1st Source decided to make an offer to purchase the portfolio back from
the Master Trust for a variety of reasons. Demand for loans, in general, and
particularly for loans for business or personal use aircraft, has remained soft,
reducing the need for external sources of funding. Moreover, the costs of
maintaining the Master Trust, including the time required to manage the issues
associated with an "off-balance-sheet" entity, continued to increase. There is
continuing debate among accounting professionals over "gain-on-sale" accounting
and related issues for recording transactions in such entities. Purchasing the
portfolio greatly simplifies the issues and enhances transparency by bringing
the loans back "on balance sheet." The purchase also enhances 1st Source's
ability to provide customers in the Master Trust with the same level of service
and product offerings it provides to its "on-balance sheet" customers and
simplifies its relationships with customers that have had loans in both
portfolios.
         The portfolio purchased includes $216 million in aircraft loans, $16
million in auto rental loans, and $2 million of loan-related assets. It also
returns to 1st Source its retained interest in the Master Trust of $25 million
in cash. The Bank has established a loss reserve of $6.8 million against the
portfolio, which is consistent with loss reserves historically maintained for
the Bank's on-balance sheet portfolios. The transaction does not materially
change 1st Source's overall loan loss reserve as a percentage of loans
outstanding, nor does it have a material impact on the results of operations in
2003.
         1st Source Bank is a subsidiary of 1st Source Corporation, the largest
locally owned financial institution headquartered in the Northern
Indiana-Southwestern Michigan area. While delivering a comprehensive range of
