Inc., effective as of the close of business on February 15, 2013, as well as
the merger of BankTrust with and into Trustmark National Bank.

Gerard R. Host, President and CEO of Trustmark, stated, “We are delighted to
expand the Trustmark franchise across Alabama, including the attractive
Mobile, Montgomery and Selma markets, as well as strengthening our franchise
along the Florida Panhandle. After months of anticipation and planning, we are
excited to welcome our newest clients and associates to the Trustmark family.
We have dedicated significant time and resources in preparation for the merger
to ensure a seamless transition and integration process and will be
communicating directly with each customer with detailed information about the
transition of their accounts to Trustmark. At this time, BankTrust customers
should continue to conduct their banking business as usual, using existing
branches, checks and ATM or debit cards until the completion of system changes
during the weekend of March 23-24. Beginning March 25, 2013, BankTrust
customers will have an expanded offering of products and services, as well as
the convenience provided by more than 170 additional Trustmark banking centers
in Florida, Mississippi, Tennessee and Texas.”

Subject to the terms of the merger agreement with BancTrust dated May 28,
2012, Trustmark will issue approximately 2.25 million shares of its common
stock for all issued and outstanding shares of BancTrust common stock, with
holders of BancTrust common stock receiving 0.125 shares of Trustmark common
stock for each share of BancTrust common stock that they owned. BancTrust’s
registered shareholders will receive a letter of instructions describing the
procedure for exchanging their certificates.

In connection with the merger, Trustmark today completed the purchase of

Series A (the “Preferred Stock”), along with the Warrant associated with the
Preferred Stock, from the U.S. Department of Treasury.
