preparation of a Registration Statement on Form S-4 filed with
the Securities and Exchange Commission (the
“Commission”) on May 23, 2008, (the
“Registration Statement”), with respect to the
Agreement and Plan of Merger, dated as of February 26, 2008
(the “Merger Agreement”), by and among MainSource, 1st
Independence Financial Group, Inc. (“1st
Independence”) and 1st Independence Bank, Inc., and
pursuant to which 1st Independence will merge with and into
MainSource (the “Merger”). All terms used herein,
