       Mortgage Servicing Rights Sale Completed By 1st Source Corporation

         South Bend, IN--1st Source Corporation (Nasdaq:SRCE) today reported the
 signing of a  definitive  agreement  and  completion  of a $1.0 billion sale of
 mortgage  servicing rights held by its Trustcorp  Mortgage Company  subsidiary.
 The preliminary  agreement was executed and announced on January 17, 2001. This
 action  generated  in excess  of $6.5  million  in net  income  for 1st  Source
 Corporation  in the first  quarter of 2001.  1st Source  expects to release its
 first  quarter,  2001  earnings  on April 24,  2001 in concert  with its annual
 meeting.
         According  to  Christopher  J.  Murphy  III,  Chairman  of  1st  Source
 Corporation,  "The  business  cycles at the  close of last  year had  created a
 strong  demand for  mortgage  servicing.  This  presented  1st  Source  with an
 opportunity  to  maximize  the value of a portion  of the  servicing  portfolio
 managed by  Trustcorp  Mortgage  Company.  With a reduction in rates early this
 year,  our loan  origination  in both 1st Source and  Trustcorp  continues at a
 quick pace."
         1st Source Corporation takes pride in its identification as the largest
 locally   owned   financial   institution   headquartered   in   the   Northern
 Indiana-Southwestern  Michigan area. While delivering a comprehensive  range of
 consumer and commercial  banking  services,  1st Source Bank has  distinguished
 itself with innovative  products and highly personalized  services.  1st Source
 also  competes  for  business  nationally  by  offering  specialized  financing
 services  for  used  private  aircraft,  automobiles  for  leasing  and  rental
 agencies, heavy duty trucks, construction and environmental equipment.
