Trustmark Corporation Selected to Participate in U.S. Treasury Capital Purchase Program

Jackson, Miss. – November 6, 2008 – Trustmark Corporation (NASDAQ:TRMK) has received preliminary approval from the U.S. Treasury Department to participate in its Capital Purchase Program, a voluntary initiative for U.S. financial institutions designed to support the economy by increasing financing to businesses and consumers.  Under this program, Trustmark intends to issue $215 million in nonvoting senior preferred stock to the U.S. Treasury.  Trustmark’s senior preferred shares will pay a cumulative annual dividend rate of 5% for the first five years and will reset to an annual rate of 9% after year five.  These senior preferred shares are callable by Trustmark at par after three years. Trustmark may call them during the first three years, but only with the proceeds of newly-issued Tier 1 equity capital in an amount of at least 25% of the $215 million.

Richard G. Hickson, Chairman and CEO stated, “We believe the U.S. Treasury Capital Purchase Program provides an outstanding opportunity for strong, healthy banks like Trustmark to support the recovery of the U.S. economy.  This cost-effective capital will support Trustmark’s growth and expansion opportunities.  We chose to voluntarily apply for the program in order to support the Treasury’s efforts to facilitate additional lending in our markets.”

In conjunction with the purchase of Trustmark’s senior preferred shares, the Treasury will receive warrants to purchase Trustmark common shares with an aggregate market value equal to $32.3 million, or 15% of the senior preferred stock investment.  The Trustmark common stock underlying these warrants will represent less than 3% of Trustmark’s outstanding common shares at September 30, 2008, at current market prices.  The exercise price will be the market price of Trustmark’s common stock at the time of issuance, calculated on a 20 trading day trailing average.  This approval is subject to the completion of standard closing conditions and the execution of the closing documents.  The U.S. Treasury intends that the purchase will occur within 30 days.

Trustmark is a financial services company providing banking and financial solutions through over 150 offices and 2,600 associates in Florida, Mississippi, Tennessee and Texas.
