Please provide to us and revise the first paragraph to report revenues, profit or loss and total assets for each of the last three fiscal years as required by Item 101(b) of Regulation S-K. 2. Please provide to us and revise the second paragraph to describe the general development of the business of you, your subsidiaries and any predecessor(s) during the past five years (and earlier) as required by Item 101(a) of Regulation S-K. In this regard, add disclosure for, among other things, the acquisitions, such as Republic, as well as asset, revenue, and equity growth over the last five years. 3. Please provide to us and revise the second paragraph to describe the business done and intended to be done by you, as required by Item 101 (c)(1) of Regulation S-K. Please address any changes in your business as a result of the recession including drops in loans and deposits, increases in defaults and foreclosures and increases in borrowings from the federal government. We note that you devote over four pages to describing bank regulation but only one page to describing your business. In this regard, also briefly describe any changes in policies and/or programs to prevent or minimize foreclosures, any changes in the standards you use to extend credit and any changes in the number or amounts of loans you originate. 4. Please provide to us and revise the first paragraph to describe the principal products produced and services rendered by you (instead of an incomplete list of "significant services") and the principal markets for, and methods of distribution of, the segment`s principal products and services as required by Item 101(c)(1)(i) of Regulation S-K. Disclose revenues from each of the four states in which you operate and the percentage of your loans in each state. Competition, page 3 5. Please provide to us and revise this section to describe competitive conditions (beyond simply stating that you have "significant competition"),as required by Item 101(c)(1)(x) of Regulation S-K, including but not limited to the following: * the identity of the particular markets in which you compete; * an estimate of the number of your competitors that operate in those markets; * an estimate of your competitive position; and * identify and explain positive and negative factors pertaining to your competitive position. Please give separate consideration to the principal products or services or classes of products or services of the segment. Please discuss the extent to which you compete with national and international financial institutions that have far greater resources and are able to offer lower rates on loans and higher rates on deposits than you and offer a broader range of products and services. Risk Factors, page 9 6. Please provide to us and revise the introductory paragraph to this section consistent with sample comment 30 to Staff Legal Bulletin No.7 and Item 503(c) which requires that you must disclose all risks that you believe are material at the time you file the Form 10-K. Please delete references to "among others" and "certain risks." Please clarify that in the last sentence that you are qualifying your report by the risks factors that are included rather than the ones that are not included. 7. Please provide to us and revise this section to comply with Item 503(c) of Regulation S-K which requires that you disclose in this section "the most significant factors that make the offering speculative or risky." Item 503(c) specifically directs notes that an issuer should not present risks that apply to any issuer or any offering. Please review all risks and remove those that do not comply including, but not limited to, those relating to controls and procedures, technology change, lawsuits in the ordinary course of business, natural disasters. 8. Please provide to us and revise each of your subcaptions, to comply with the following: * Item 503(c) which requires that you set forth each risk factor under a subcaption that adequately describes the risk; * sample comment 36 to Staff Legal Bulletin No.7, which directs that you revise each subheading to "ensure it reflects the risk that you discuss in the text." rather than "merely state a fact about your business...succinctly state in your subheadings the risks that result from the facts or uncertainties;" and * sample comment 37 to Staff Legal Bulletin No.7, which directs that you revise each subheading to eliminate language that is "too vague and generic to adequately describe the risk that follows." For instance, the caption to your first risk factor which merely states "Trustmark is subject to interest rate risk" does not comply with the applicable requirements. 9. Please provide to us and revise each risk factor to comply with the following: * Securities Act Release No. 33-7497 which requires that you "place any risk factor in context so investors can understand the specific risk as it applies to your company and its operations;" * sample comment 34 to Staff Legal Bulletin No.7, which directs that you provide the information investors need to "assess the magnitude" of each risk and "explain why" each risk may result in a material adverse effect on you; and * sample comment 38 to Staff Legal Bulletin No.7, which directs that you include "specific disclosure of how your [operations] [financial condition] [business] would be affected" by each risk. For instance, in the first risk factor, please discuss the specific interest rate risks that you face including the extent to which you loan portfolio includes adjustable rate loans. For instance, in the second risk factor, discuss the risks associated with the market conditions in your specific markets, particularly Florida, such as the rise in foreclosures and loan defaults and the decline in the housing starts and housing prices. For instance, in the third risk factor discuss the risks from specific portions of your loan portfolio. 10. Consider adding a risk factor relating to your liquidity and regulatory capital given your borrowings $215 million from the Treasury`s TARP program and $200 million Federal Reserve`s TAF program as well as your increase in Federal funds purchased from $279 million in 2007 to $616 million in 2008. Management`s Discussion and Analysis of Financial Condition and Results of Operations, page 19 11. Please provide to us and revise to include an overview with meaningful disclosure and analysis relating to your business condition, financial condition and results of operations consistent with Release No. 33-8350 including, but not limited to, the following: * provide a balanced, executive-level discussion that identifies the most important themes or other significant matters with which management is concerned primarily in evaluating the company`s financial condition and operating results; * identify and provide insight into material opportunities, challenges and risks that you face, on which your executives are most focused for both the short and long term such as: * your need for additional capital as evidenced by your dramatic increase in borrowings from the Federal government; * how you have been effected by the financial and credit crisis; * the extent of your loan portfolio attributable to real estate loans; * the economic recession in your market areas; * the rise of loan defaults and foreclosures at your institution; * the drop in real estate prices, real estate sales and new construction in your market areas; and * the rise in unemployment in your market areas; and * identify and provide insight into the actions you are taking to address each of the serious challenges and risks that you face including, but not limited to, changes your standards for making loans and for investing in securities and plans to raise additional capital through government programs and/or other means. Critical Accounting Policies, pages 19-21 General 12. Since critical accounting estimates and assumptions are based on matters that are highly uncertain, please revise to provide additional disclosure for each of your critical estimates to analyze their specific sensitivity to change, based on other outcomes that are reasonably likely to occur and would have a material effect. Provide quantitative as well as qualitative disclosure when quantitative information is reasonably available and will provide material information for investors. For example, if reasonably likely changes in the long-term rate of return used in accounting for a company`s pension plan would have a material effect on the financial condition or operating performance of the company, the impact that could result given the range of reasonably likely outcomes should be disclosed and, because of the nature of estimates of long-term rates of return, quantified. Financial Highlights, page 22 13. Please provide to us and revise this section in its entirety to comply with Item 303 and Release No. 33-8350 by identifying and analyzing known trends, events, demands, commitments and uncertainties that are reasonably likely to have a material effect on your financial condition or operating performance including, but not limited to, analysis of the following: * how the deterioration of the real estate market and the economy in your markets has affected you and how the continued deterioration may affect you; * how the carrying amount of your investment securities (level 2) and loans held for sale may be overvalued due to dramatic decline in the market value of these assets; * trends in the number and percentage of your loans that are overdue by 60 days or more; * trends in the number and percentage of your loans that have defaulted or foreclosed; and * trends in the provision for loan losses. 14.

Please distinguish between consumer loans and commercial loans. 16. Please provide to us and revise to include a separate section at the front of the MD&A section which analyzes your $215 million loan from the U.S. Treasury under the Troubled Asset Relief Program including, but not limited to, analysis of the following: * the reasons why you applied for the $215 million loan: * the material terms of the transaction including the material terms of the securities and warrants you issued to the Treasury Department; and * how you have used the $215 million in proceeds. 17.

Segment Information Administration, page 32 18. We note you plan to reduce your reporting segments from four to three by combining Administration into General Banking because the revenues and expenses reflected in Administration are directly related to General Banking. Please reconcile this to the first sentence where you indicate Administration includes all other activities that are not directly attributable to one of the major lines of business. Also, tell us if there has been a change in the information evaluated regularly by your chief operating decision maker. Securities, page 32 19.
