Premier Bank Chairman and CEO Jim Harris, a co-founder of the bank, said, "Our
merger with BancorpSouth will give us the opportunity to grow more rapidly to
serve this dynamic market. BancorpSouth has an established presence here with
plans to grow steadily in this market. Joining with BancorpSouth will provide
our customers opportunities offered by a large, resourceful, community-minded
bank. We are truly excited about merging with BancorpSouth."

Premier Bank President Diane West said, "When the merger is complete, our
customers will have all of the advantages and services of an $11 billion bank
with the local, hometown customer service to which they have become accustomed
and for which BancorpSouth is known in our industry."

"This is truly a mutually beneficial partnership," said BancorpSouth Chairman
and CEO Aubrey Patterson. "We established a loan production office in
Brentwood's Maryland Farms area two years ago and have since expanded it to
full-service banking. We have been actively seeking other banking locations in
the Brentwood and Franklin areas to expand our presence in Williamson County.
This new partnership certainly accelerates our opportunity to grow in Williamson
County and brings to BancorpSouth's team a number of outstanding bankers."

grow, and we are pleased to have the opportunity to serve additional customers
in the greater Nashville market. We currently have 33 banking locations with
combined deposits exceeding $1.0 billion in 20 Tennessee cities, primarily in
Memphis, Jackson and the West Tennessee area. We see Brentwood and Williamson
County as a logical growth area for BancorpSouth's community style of banking."
Williamson County is ranked third in the U.S. with most growth potential and
prosperity by American City Business Journal.

Today, in a concurrent event, BancorpSouth also announced the signing of a
definitive merger agreement with Business Holding Corporation of Baton Rouge,
Louisiana, parent company of The Business Bank of Baton Rouge, a $163.7 million
asset commercial bank established in 1998.
