JACKSON, Miss. & MOBILE, Ala. -- January 24, 2013

Trustmark Corporation (NASDAQ:TRMK) (“Trustmark”) and BancTrust Financial
Group, Inc. (NASDAQ:BTFG) (“BancTrust”) announced today that all required
regulatory approvals have been received in connection with the proposed merger
of BancTrust into Trustmark. Subject to customary closing conditions contained
in the merger agreement, the transaction is expected to be effective as of the
close of business on Friday, February 15, 2013. BankTrust customers should
continue to conduct their banking business as usual, using existing branches,
checks and ATM or debit cards, until receiving notice from Trustmark that
system changes have been completed, which is expected to occur by the end of
the first quarter of 2013. At that point, BankTrust customers will have an
expanded offering of products and services, as well as the added convenience
provided by more than 170 Trustmark banking centers in Florida, Mississippi,
Tennessee and Texas.

“We look forward to welcoming customers and associates of BancTrust to the
Trustmark family. Expansion into attractive Alabama markets, including Mobile
and Montgomery, as well as increasing scale in existing Florida Panhandle
markets, represents a great opportunity for Trustmark,” said Gerard R. Host,
President and CEO of Trustmark.

W. Bibb Lamar, Jr., President and CEO of BancTrust, stated, “We are delighted
to be joining forces with Trustmark and look forward to continuing to serve
our customers as part of a strong, $12 billion regional banking organization.”
