Form 10-K

Business, page 3

1. Please provide to us and revise the first paragraph to report
revenues, profit or loss and total assets for each of the last

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:

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;

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

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.

comply with Item 303 and Release No. 33-8350 by identifying and

not
limited to, analysis of the following:

in

the
market value of these assets;
* trends in the number and percentage of your loans that are

* trends in the number and percentage of your loans that have
defaulted or foreclosed; and

and
benefits to you of each, including but not limited to the
following:
* $215 million from the U.S. Treasury`s Troubled Assets Relief
Program;
* $200 million in short term loans from Federal Reserve`s Term
