SOUTH BEND, Ind.--(BUSINESS WIRE)--Jan. 17, 2001

1st Source Corporation (Nasdaq:SRCE) reported today it has executed an agreement to sell $1.0 billion in mortgage servicing rights currently held by its Trustcorp Mortgage Company subsidiary. A definitive agreement is expected to be signed by February 28, 2001 if completed as agreed. This action will generate approximately $6.0 million in net income for 1st Source Corporation in the first quarter of 2001.

According to Christopher J. Murphy III, Chairman of 1st Source Corporation, "Recent business cycles in the mortgage banking industry have created a strong demand for mortgage servicing. This has presented 1st Source with an opportunity to maximize the value of a portion of the servicing portfolio managed by Trustcorp Mortgage Company by selling it to investors who place a higher value on the servicing than Trustcorp believes it can earn by retaining it. This transaction will enable 1st Source to reallocate resources and capital to insure growth and competitive returns from its investment in mortgage origination and servicing. The management of Trustcorp has proposed this transaction as a way of improving the long term returns on the 1st Source investment in the mortgage banking business."
