ITEM 1. BUSINESS

GENERAL

Trustmark is a multi-bank holding company headquartered in Jackson, Mississippi,
incorporated under the Mississippi Business Corporation Act on August 5, 1968.
Trustmark commenced doing business in November 1968. Through its subsidiaries,
Trustmark operates as a financial services organization providing banking and
financial solutions to corporate, institutional and individual customers
predominantly within the states of Florida, Mississippi, Tennessee and Texas.

Trustmark National Bank (TNB), Trustmark's wholly-owned subsidiary, accounts for
substantially all of the assets and revenues of Trustmark. Chartered by the
state of Mississippi in 1889, TNB is also headquartered in Jackson, Mississippi.
In addition to banking activities, TNB provides investment and insurance
products and services to its customers through four wholly-owned subsidiaries,
Trustmark Securities, Inc. (formerly Trustmark Financial Services, Inc.),
Trustmark Investment Advisors, Inc., The Bottrell Insurance Agency, Inc.
(Bottrell) and Fisher-Brown, Inc. In January 2005, Trustmark established a de
novo subsidiary, Trustmark Risk Management, Inc. (TRMI). TRMI commenced doing
business on January 31, 2005, and engages in insurance agency activities as an
agent for individual life, disability and long-term care insurance, and also as
agent for the sale of fixed annuities.

Trustmark also engages in banking activities through its wholly-owned
subsidiary, Somerville Bank & Trust Company (Somerville), headquartered in
Somerville, Tennessee. Somerville was acquired in a business combination during
2001 and presently has five locations in Somerville, Hickory Withe and
Rossville, Tennessee. In addition to its banking subsidiaries, Trustmark also
owns all of the stock of F. S. Corporation and First Building Corporation, both
inactive nonbank Mississippi corporations. Neither Trustmark nor its
subsidiaries have any foreign activities. As of December 31, 2004, Trustmark and
its subsidiaries employed 2,598 full-time equivalent employees.

Segments

During the first quarter of 2004, Trustmark realigned its management reporting
structure to include the following divisions: General Banking, Wealth
Management, Insurance and Administration. The General Banking Division realigns
Trustmark's former Consumer and Commercial Division into a single group. In
addition, Trustmark realigned its former Investment Division into the Wealth
Management Division incorporating trust, brokerage, investment advisory and
private banking services under one umbrella. The Insurance Division, formerly
included in the Consumer Division, represents Trustmark's retail insurance
agencies that offer a diverse mix of insurance products and services. The
Administration Division incorporates Trustmark's treasury function with various
non-allocated corporate operations units and includes intangible assets and
related amortization (except mortgage servicing rights and related amortization,
which is included in the General Banking Division).

General Banking Division
The General Banking Division is responsible for all traditional banking products
and services, including loans and deposits. Management of the General Banking
Division is primarily coordinated through the Metro and Community Banking Group,
Corporate Group, Customer Products and Services Group and Mortgage Banking.

The Metro and Community Banking Group provides a full range of consumer banking
services, including checking accounts, savings programs, overdraft facilities,
installment and real estate loans, home equity loans and lines of credit,
drive-in and night deposit services and safe deposit facilities for Trustmark's
149 retail offices in Florida, Mississippi, Tennessee and Texas. Customers may
access automated teller machines (ATM) through Trustmark's network of 189 ATMs
in 173 locations in Florida, Mississippi, Tennessee and Texas, in addition to
worldwide access through other ATM networks such as Plus, Pulse and Cirrus.

The Corporate group includes Corporate Lending, Corporate and Residential Real
Estate and Corporate Services. Through these business units, the Corporate group
offers specialized lending for a variety of customers, financing for commercial
real estate development projects, residential real estate financing for
builders, developers and individuals and cash management products to existing
corporate customers and prospects, as well as the development of Internet
banking for business clients.
The Customer Products and Services group provides support to the wide variety of
lines of business within the bank and to the geographies in which products and
services are delivered. Business units within this group include Lending
Services, Relationship Management, Marketing, Delivery Services and Knowledge
Management. Lending Services encompass the management of underwriting for small
business and consumer loans, central document loan preparation, government loan
administration and underwriting and sales of all credit card and non-card
revolving credit products. In addition, the dealer services business unit
coordinates the underwriting and funding for indirect automobile loans from a
network of dealers throughout the Southeast. Relationship Management implements
and maintains sale and services training. Marketing assists all lines of
business within Trustmark through the coordination of product development,
development of sales campaigns and assisting market managers by providing
research and market analytics to aid in customer calling efforts. Delivery
Services manages self-service customer products such as TrustTouchWeb and
TrustNetWeb; Trustmark's Internet banking products for personal and business
use. Knowledge Management coordinates associate development by managing
Trustmark's Corporate University, which offers both traditional classroom and
on-line courses to deliver knowledge and skills to Trustmark associates.

The Mortgage Banking group provides a full complement of mortgage products
through Production, Secondary Marketing and Loan Servicing working units. The
Production unit is comprised of both a retail and wholesale production network.
The retail production network assists individual banking customers through the
origination and processing phases of mortgage application, while the wholesale
production network handles the funding and insuring of loans originated through
correspondent relationships. Underwriting and documentation are also handled in
Production. Secondary Marketing is the process of bundling packages of mortgage
loans for sale in the secondary market. Also included in this process are
hedging and pricing activities which allow Trustmark to more successfully manage
the interest rate and market risk associated with this activity. Loan Servicing
is a significant line of business for Trustmark involving the retention of
servicing rights associated with individual loans. As such, Trustmark remains
the processor of payment for customers' mortgages and retains a fee for the
services rendered. Specific duties include Investor/Cash Management, Escrow
Processing and Default Management.

Wealth Management Division
Trustmark's Wealth Management Division has been strategically organized to serve
our customers as a financial partner providing reliable guidance and sound,
practical advice for accumulating, preserving, and transferring wealth. This
division specializes in providing customized solutions for affluent customers by
integrating financial services with traditional banking products and services.
Wealth Management manages and administers over $7 billion in client assets by
providing services such as private banking, money management, full-service
brokerage, financial planning, risk management, personal and institutional
trust, and retirement plan services.

Several wholly-owned subsidiaries of Trustmark National Bank are included in
Wealth Management. Trustmark Securities, Inc. is a full service brokerage firm
registered with the National Association of Securities Dealers. Trustmark
Investment Advisors, Inc. is a registered investment adviser that provides
investment management services to individual and institutional accounts as well
as The Performance Family of Mutual Funds. TRMK Risk Management, Inc. provides
insurance solutions for Wealth Management clients.
Insurance Division
Trustmark's Insurance Division now includes two wholly-owned subsidiaries of
TNB: The Bottrell Insurance Agency and Fisher-Brown, Incorporated. Through
Bottrell, Trustmark provides a full range of retail insurance products,
including commercial risk management products, bonding, group benefits and
personal lines coverages. With the acquisition of Chandler-Sampson Insurance
Agency during 2002, Bottrell was able expand its customer base in school,
medical malpractice and mid-market business insurance. In May 2004, Bottrell
initiated the offering of wholesale insurance through its Frontline Underwriters
department specializing in transportation risks. In December 2004, Trustmark
continued to expand insurance services, as well as its presence in the Florida
panhandle, with the acquisition of Fisher-Brown, Incorporated, Northwest
Florida's leading insurance agency headquartered in Pensacola, with offices in
Milton, Mary Esther, Destin and Panama City. Fisher-Brown operates as a
full-service insurance agency, selling a broad spectrum of insurance to
businesses and individuals. Fisher-Brown's approach is one of total risk
management, encompassing the areas of property and liability insurance,
automotive insurance, worker's compensation, professional liability, group
accident and health insurance, life insurance, contract surety bonds, and
personal insurance.

Administration Division
Trustmark's Administration Division includes all other activities that are not
directly attributable to one of the major lines of business. The Administration
Division consists of internal operations such as Human Resources, Executive
Administration, Property Management and Corporate Finance. Business units
include Treasury Administration, Controller's Division, Corporate Planning,
Employee Relations, Employee Benefits, HR Information Systems, Compensation and
Payroll.

Additional information on Trustmark's segments can be found in Note 19, "Segment
Information," included in Trustmark's 2004 Annual Report to Shareholders and is
incorporated herein by reference.

Available Information

Trustmark's internet address is www.trustmark.com. Trustmark makes available
through this address, free of charge, its annual report on Form 10-K, quarterly
reports on Form 10-Q, current reports on Form 8-K and amendments to those
reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange

Business Combinations

On December 1, 2004, Trustmark acquired Fisher-Brown, Incorporated, northwest
Florida's leading insurance agency located in Pensacola, Florida. This business
combination was accounted for under the purchase method of accounting. Excess
cost over tangible net assets acquired totaled $36.2 million, of which $9.3
million and $26.9 million have been allocated to identifiable intangibles and
goodwill, respectively.

On March 12, 2004, Trustmark acquired five branches of Allied Houston Bank in a
business combination accounted for by the purchase method of accounting. In
connection with the transaction, Trustmark acquired approximately $148.1 million
in assets and assumed $161.7 million in deposits and other liabilities for a $10
million deposit premium. Assets consisted of $145.9 million in loans, $585
thousand in premises and equipment and $1.6 million in other assets. The assets
and liabilities have been recorded at fair value based on market conditions and
risk characteristics at the acquisition date. Loans were recorded at a $6.4
million discount, consisting of a discount for general credit risk of $7.3
million offset by a market valuation premium of $862 thousand. Included in the
credit risk discount of $7.3 million was a specific amount for nonaccrual loans
of $1.7 million. Subsequent to the purchase date, the unpaid principal for these
nonaccrual loans were written down to their net realizable value against the
recorded discount. Excess cost over tangible net assets acquired totaled $15.7
million, of which $426 thousand and $15.3 million have been allocated to
identifiable intangibles (core deposits) and goodwill, respectively.
Forward-Looking Statements

Certain statements contained in Management's Discussion and Analysis are not
statements of historical fact and constitute forward-looking statements within
the meaning of the Private Securities Litigation Reform Act of 1995. These
forward-looking statements relate to anticipated future operating and financial
performance measures, including net interest margin, credit quality, business
initiatives, growth opportunities and growth rates, among other things and
encompasses any estimate, prediction, expectation, projection, opinion,
anticipation, outlook or statement of belief included therein as well as the
management assumptions underlying these forward-looking statements. Should one
or more of these risks materialize, or should any such underlying assumptions
prove to be significantly different, actual results may vary significantly from
those anticipated, estimated, projected or expected. These risks could cause
actual results to differ materially from current expectations of Management and
include the following:

o The level of nonperforming assets, charge-offs and provision expense can be
affected by local, state and national economic and market conditions as
well as Management's judgments regarding collectability of loans.
o Material changes in market interest rates can materially affect many
aspects of Trustmark's financial condition and results of operations.
Trustmark is exposed to the potential of losses arising from adverse
changes in market interest rates and prices which can adversely impact the
value of financial products, including securities, loans, deposits, debt
and derivative financial instruments. Factors that may affect the market
interest rates include local, regional and national economic conditions;
utilization and effectiveness of market interest rate contracts; and the
availability of wholesale and retail funding sources to Trustmark. Many of
these factors are outside Trustmark's control.
o Increases in prepayment speeds of mortgage loans resulting from a
historically low interest rate environment would have an impact on the fair
value of the mortgage servicing portfolio. In addition, premium
amortization on mortgage related securities included in Trustmark's
securities portfolio would also be accelerated as prepayment of the
mortgage loans securing these securities occur. The combination of these
events could materially affect Trustmark's results of operations.
o The costs and effects of litigation and of unexpected or adverse outcomes
in such litigation can materially affect Trustmark's results of operations.
o Competition in loan and deposit pricing, as well as the entry of new
competitors into our markets through de novo expansion and acquisitions,
among other means, could have an effect on Trustmark's operations in our
existing markets.
o Trustmark is subject to regulation by federal banking agencies and
authorities and the Securities and Exchange Commission. Changes in existing
regulations or the adoption of new regulations could make it more costly
for Trustmark to do business or could force changes in the manner Trustmark
does business, which could have an impact on Trustmark's financial
condition or results of operations.

Although Management believes that the expectations reflected in such
forward-looking statements are reasonable, it can give no assurance that such
expectations will prove to be correct. Trustmark undertakes no obligation to
update or revise any of this information, whether as the result of new
information, future events or developments, or otherwise.

COMPETITION

Changes in regulation, technology and product delivery systems have resulted in
an increasingly competitive environment. Trustmark and its subsidiaries compete
with other local, regional and national providers of banking, investment and
insurance products and services such as other bank holding companies, commercial
and state banks, savings and loan associations, consumer finance companies,
mortgage companies, insurance agencies, brokerage firms, credit unions and
financial service operations of major retailers. Trustmark competes in its
markets by offering quality and innovative products and services at competitive
prices. Within Trustmark's market area, none of the competitors are dominant.

SUPERVISION AND REGULATION

The following discussion sets forth certain material elements of the regulatory
framework applicable to bank holding companies and their subsidiaries and
provides certain specific information relevant to Trustmark.
General
Trustmark is a registered bank holding company under the Bank Holding Company
Act (BHC) of 1956, as amended. As such, Trustmark and its nonbank subsidiaries
are subject to the supervision, examination and reporting requirements of the
BHC Act and the regulations of the Federal Reserve Board. In addition, as part
of Federal Reserve policy, a bank holding company is expected to act as a source
of financial and managerial strength to subsidiary banks and to maintain
resources adequate to support each subsidiary bank. The BHC Act requires every
bank holding company to obtain the prior approval of the Federal Reserve before:
(i) it may acquire direct or indirect ownership or control of any voting shares
of any bank if, after such acquisition, the bank holding company will directly
or indirectly own or control more than 5.0% of the voting shares of the bank;
(ii) it or any of its subsidiaries, other than a bank, may acquire all or
substantially all of the assets of any bank; or (iii) it may merge or
consolidate with any other bank holding company.

The BHC Act further provides that the Federal Reserve may not approve any
transaction that would result in a monopoly or would be in furtherance of any
combination or conspiracy to monopolize or attempt to monopolize the business of
banking in any section of the United States, or the effect of which may be
substantially to lessen competition or to tend to create a monopoly in any
section of the country, or that in any other manner would be in restraint of
trade, unless the anticompetitive effects of the proposed transaction are
clearly outweighed by the public interest in meeting the convenience and needs
of the community to be served. The Federal Reserve is also required to consider
the financial and managerial resources and future prospects of the bank holding
companies and banks concerned and the convenience and needs of the community to
be served. Consideration of financial resources generally focuses on capital
adequacy, and consideration of convenience and needs issues includes the
parties' performance under the Community Reinvestment Act of 1977.

The BHC Act, as amended by the interstate banking provisions of the Riegle-Neal
Interstate Banking and Branching Efficiency Act of 1994 repealed the prior
statutory restrictions on interstate acquisitions of banks by bank holding
companies, such that Trustmark may now acquire a bank located in any other
state, regardless of state law to the contrary, subject to certain
deposit-percentage, aging requirements, and other restrictions. The Interstate
Bank Branching Act also generally provided that, after June 1, 1997, national
and state-chartered banks may branch interstate through acquisitions of banks in
other states.

In addition, bank holding companies generally may engage, directly or
indirectly, only in banking and such other activities as are determined by the
Federal Reserve Board to be closely related to banking. Trustmark is also
subject to regulation by the State of Mississippi under its general business
corporation laws. In addition to the impact of regulation, Trustmark and its
subsidiaries may be affected by legislation which can change banking statutes in
substantial and unexpected ways, and by the actions of the Federal Reserve Board
as it attempts to control the money supply and credit availability in order to
influence the economy.

TNB is a national banking association and, as such, is subject to regulation by
the Office of the Comptroller of the Currency (OCC), the Federal Deposit
Insurance Corporation (FDIC) and the Federal Reserve Board. Almost every area of
the operations and financial condition of TNB is subject to extensive regulation
and supervision and to various requirements and restrictions under federal and
state law including loans, reserves, investments, issuance of securities,
establishment of branches, capital adequacy, liquidity, earnings, dividends,
management practices and the provision of services. Somerville is a
state-chartered commercial bank, subject to regulation primarily by the FDIC and
secondarily by the Tennessee Department of Financial Institutions.

TNB's nonbanking subsidiaries are subject to a variety of state and federal
laws. Trustmark Securities, Inc. is subject to supervision and regulation by the
SEC, the National Association of Securities Dealers, Inc., state securities
regulators and the various exchanges through which it conducts business. TIA, a
registered investment advisor, is subject to supervision and regulation by the
SEC and the state of Mississippi. Bottrell, Fisher-Brown and TRMI are subject to
the insurance laws and regulations of the states in which they are active. The
Federal Reserve Board supervises Trustmark's nonbanking subsidiaries.

Trustmark is also under the jurisdiction of the SEC for matters relating to the
offering and sale of its securities. Trustmark is subject to the disclosure and
regulatory requirements of the Securities Act of 1933, as amended, and the
Securities Exchange Act of 1934, as amended, as administered by the SEC.
The  Gramm-Leach-Bliley  Financial Services  Modernization Act of 1999 (Act) was
signed into law on November 12, 1999. As a result of the Act, banks are able to
offer customers a wide range of financial products and services without the
restraints of previous legislation. In addition, bank holding companies and
other financial services providers have been able to commence new activities and
develop new affiliations much more readily. The primary provisions of the Act
related to the establishment of financial holding companies and financial
subsidiaries became effective on March 11, 2000. The Act authorizes national
banks to own or control a "financial subsidiary" that engages in activities that
are not permissible for national banks to engage in directly. The Act contains a
number of provisions dealing with insurance activities by bank subsidiaries.
Generally, the Act affirms the role of the states in regulating insurance
activities, including the insurance activities of financial subsidiaries of
banks, but the Act also preempts certain state laws. As a result of the Act, TNB
elected for Bottrell, Fisher-Brown and TRMI to become financial subsidiaries.
This enables TNB to engage in insurance agency activities through its financial
subsidiaries at any location.

The Act also imposed new requirements related to the privacy of customer
financial information. The Act requires financial institutions to disclose their
information sharing policies and procedures, and if the institution shares
information with nonaffiliated third parties, the institution must provide
customers with the opportunity to "opt out" of the sharing arrangements. The Act
also prohibits financial institutions from disclosing a customer's account
number to nonaffiliated third parties for use in marketing programs, including
telemarketing and direct mail programs. Finally, the Act prohibits most persons
from obtaining customer information through the use of false, fictitious or
fraudulent statements or representations. Trustmark has complied with these
requirements and recognizes the need for its customers' privacy.

Anti-Money Laundering Initiatives and the USA Patriot Act
A major focus of governmental policy on financial institutions in recent years
has been aimed at combating money laundering and terrorist financing. The USA
PATRIOT Act of 2001 (the USA Patriot Act) substantially broadened the scope of
United States anti-money laundering laws and regulations by imposing significant
new compliance and due diligence obligations, creating new crimes and penalties
and expanding the extra-territorial jurisdiction of the United States. The
United States Treasury Department has issued a number of implementing
regulations that apply to various requirements of the USA Patriot Act to
financial institutions such as Trustmark's bank and broker-dealer subsidiaries.
These regulations impose obligations on financial institutions to maintain
appropriate policies, procedures and controls to detect, prevent and report
money laundering and terrorist financing and to verify the identity of their
customers. Failure of a financial institution to maintain and implement adequate
programs to combat money laundering and terrorist financing, or to comply with
all of the relevant laws or regulations, could have serious legal consequences
for the institution.

Sarbanes-Oxley Act of 2002
During the fiscal year 2004, Section 404 of the Sarbanes-Oxley Act of 2002
(SOX), which has as its purpose the improvement of corporate governance and
reporting, directly impacted Trustmark. The Act calls for accelerated filers to
comply by December 31, 2004 while non-accelerated filers have until December 31,
2005. Those who have a market capitalization greater than $75 million are
considered accelerated filers and Trustmark falls into this category. The major
part of SOX is Section 404 that requires companies to provide a report on their
internal controls over financial reporting. This internal control report must
(1) state the responsibility of Management for establishing and maintaining an
adequate internal control structure and procedures for financial reporting; and
(2) contain an assessment, as of the end of the most recent fiscal year of the
issuer, of the effectiveness of the internal control structure and procedures of
the issuer for financial reporting. This assessment of internal controls over
financial reporting requires Management to maintain evidential matter, including
documentation, to support its assessment. Section 404 also requires an
Attestation Report from the issuer's registered public accounting firm. Please
see Item 9A, "Controls and Procedures" for more information.

Capital Adequacy
Trustmark is subject to capital requirements and guidelines imposed on bank
holding companies by the Federal Reserve Board. The OCC imposes similar capital
requirements and guidelines on TNB. Somerville is not discussed in this section
as it is not a significant subsidiary as defined by the SEC. These capital
guidelines involve quantitative and qualitative measures of assets, liabilities
and certain off-balance sheet instruments.
Trustmark  and TNB are required to maintain Tier 1 and total capital equal to at
least 4% and 8% of their total risk-weighted assets, respectively. At December
31, 2004, Trustmark exceeded both requirements with Tier 1 capital and total
capital equal to 10.39% and 11.55% of its total risk-weighted assets,
respectively. At December 31, 2004, TNB also exceeded both requirements with
Tier 1 capital and total capital equal to 9.92% and 11.06% of its total
risk-weighted assets, respectively.

The Federal Reserve Board also requires bank holding companies to maintain a
minimum leverage ratio. The guidelines provide for a minimum leverage ratio of
3% for banks and bank holding companies that meet certain specified criteria,
including having the highest regulatory rating. At December 31, 2004, the
leverage ratios for Trustmark and TNB were 7.22% and 6.89%, respectively.

Failure to meet minimum capital requirements could subject a bank to a variety
of enforcement remedies. The Federal Deposit Insurance Corporation Improvement
Act of 1991 (FDICIA), among other things, identifies five capital categories for
insured depository institutions. These include well capitalized, adequately
capitalized, undercapitalized, significantly undercapitalized and critically
undercapitalized. FDICIA requires banking regulators to take prompt corrective
action whenever financial institutions do not meet minimum capital requirements.
Failure to meet the capital guidelines could also subject a depository
institution to capital raising requirements. In addition, a depository
institution is generally prohibited from making capital distributions, including
paying dividends, or paying management fees to a holding company if the
institution would thereafter be undercapitalized. As of December 31, 2004, the
most recent notification from the OCC categorized TNB as well capitalized based
on the ratios and guidelines described above.

Payment of Dividends and Other Restrictions
There are various legal and regulatory provisions which limit the amount of
dividends TNB can pay to Trustmark without regulatory approval. Approval of the
OCC is required if the total of all dividends declared in any calendar year
exceeds the total of its net income for that year combined with its retained net
income from the preceding two years. TNB will have available in 2005
approximately $64.9 million plus its net income for that year to pay as
dividends. In addition, subsidiary banks of a bank holding company are subject
to certain restrictions imposed by the Federal Reserve Act on extensions of
credit to the bank holding company or any of its subsidiaries. Further,
subsidiary banks of a bank holding company are prohibited from engaging in
certain tie-in arrangements in connection with any extension of credit, lease or
sale of property or furnishing of any services to the bank holding company.

FDIC Insurance Assessments
The deposits of TNB are insured up to regulatory limits set by the FDIC and,
accordingly, are subject to deposit insurance assessments. The FDIC has the
authority to raise or lower assessment rates on insured deposits in order to
achieve certain designated ratios in the Bank Insurance Fund (BIF) and the
Savings Association Insurance Fund (SAIF) and to impose special assessments. The
FDIC applies a risk-based assessment system that places each financial
institution into one of nine categories based on capital levels and supervisory
evaluations provided to the FDIC by the institution's primary federal regulator.
Each institution's insurance assessment rate is then determined by the risk
category in which it is classified. At December 31, 2004, TNB's annual BIF and
SAIF assessment rates and Somerville's BIF rate were $0.0144 per $100 of insured
deposits.

included in interest income. Loan fees included in interest associated with the
average loan balances are immaterial. Interest income and average yield on
tax-exempt assets have been calculated on a fully tax equivalent basis using a
tax rate of 35% for each of the three years presented. Certain reclassifications
have been made to the 2003 and 2002 amounts to conform to the 2004 presentation.

Due to the nature of mortgage related securities, the actual maturities of these
investments can be substantially shorter than their contractual maturity.
Management believes the actual weighted average maturity of the entire mortgage
related portfolio to be approximately 2.47 years.

As of December 31, 2004, Trustmark did not hold any securities of one issuer
with a carrying value exceeding ten percent of total shareholders' equity.

A loan is classified as nonaccrual and the accrual of interest on such loan is
discontinued when the contractual payment of principal or interest becomes 90
days past due or if Management has serious doubts about further collectibility
of principal or interest, even though the loan is currently performing. A loan
may remain on accrual status if it is in the process of collection and well
secured. When a loan is placed on nonaccrual status, unpaid interest is reversed
against interest income. Interest received on nonaccrual loans is applied
against principal. Loans are restored to accrual status when the obligation is
brought current or has performed in accordance with the contractual terms for a
reasonable period of time and the ultimate collectibility of the total
contractual principal and interest is no longer in doubt. A loan is considered
impaired when, based on current information and events, it is probable that
Trustmark will be unable to collect the scheduled payments of principal or
interest when due according to the contractual terms of the loan agreement. The
policy for recognizing income on impaired loans is consistent with the
nonaccrual policy.

As of December 31, 2004, Management is not aware of any additional credits,
other than those identified above, where serious doubts as to the repayment of
principal and interest exist. There are no interest-earning assets which would
be required to be disclosed above if those assets were loans. Trustmark had no
loan concentrations greater than ten percent of total loans other than those
loan categories shown in Table 6.

Explanation of the changes in 2004 can be found in the table captioned
"Nonperforming Assets" and the related discussion included in Management
DIscussion and Analysis found in the Registrant's 2004 Annual Report to
Shareholders and is incorporated herein by reference.

</TABLE>

The allowance for loan losses is established through provisions for estimated
loan losses charged against earnings. Loans deemed to be uncollectible are
charged against the allowance for loan losses, and subsequent recoveries, if
any, are credited to the allowance.

The allowance for loan losses is maintained at a level believed adequate by
management, based on estimated probable losses within the existing loan
portfolio. Trustmark's allowance for loan loss methodology is based on guidance
provided by SEC Staff Accounting Bulletin No. 102, "Selected Loan Loss Allowance
Methodology and Documentation Issues," as well as other regulatory guidance.
Accordingly, Trustmark's methodology is based on historical loss experience by
type of loan and internal risk ratings, homogeneous risk pools, and specific
loss allocations, with consideration given to current economic events and
conditions.

The allowance for loan losses consists of three elements: (i) specific valuation
allowances established for probable losses on specific loans; (ii) historical
valuation allowances calculated based on historical loan experience for similar
loans with similar characteristics and trends, and (iii) unallocated general
valuation allowances determined based on general economic conditions and other
qualitative risk factors both internal and external to Trustmark.

The provision for loan losses reflects loan quality trends, including the levels
of and trends related to non-accrual loans, past due loans, potential problem
loans, criticized loans and net charge-offs or recoveries and other factors.
During the fourth quarter of 2004, Trustmark recorded a release of $9.4 million
to the allowance for loan losses resulting from changes in estimates to specific
factors for pooled loans and a specific class of commercial loans, both of which
had experienced positive trends in loss experience. As a result, Trustmark
recognized a benefit of $3.1 million in the provision for loan losses for the
year ended December 31, 2004.
TABLE 10 - ALLOCATION OF THE ALLOWANCE FOR LOAN LOSSES

The allowance for loan losses is established through provisions for estimated
loan losses charged against earnings. Loans deemed to be uncollectible are
charged against the allowance for loan losses, and subsequent recoveries, if
any, are credited to the allowance. The allowance for loan losses is maintained
at a level believed adequate by management, based on estimated probable losses
within the existing loan portfolio. Trustmark's allowance for loan loss
methodology is based on guidance provided in SEC Staff Accounting Bulletin No.
102, "Selected Loan Loss Allowance Methodology and Documentation Issues," as
well as other regulatory guidance. Accordingly, Trustmark's methodology is based
on historical loss experience by type of loan and internal risk ratings,
homogeneous risk pools, and specific loss allocations, with consideration given
to current economic events and conditions. This evaluation is inherently
subjective, as it requires material estimates, including the amounts and timing
of future cash flows expected to be received on impaired loans that may be
susceptible to significant change.

Loss percentages are uniformly applied to pools of risk-rated loans within the
commercial portfolio. These percentages are determined based on migration
analysis, previously established floors for each category and economic factors.
In addition, relationships of $100,000 or more which are risk-rated as other
loans especially mentioned or worse are reviewed by Trustmark's Asset Review
Department staff and the Credit Quality Review Committee to determine if
standard percentages appear to be sufficient to cover probable losses. In the
event that the percentages on any particular lines are determined to be
insufficient, additional allocations are made. Industry allocations are made
based on concentrations of credit within the portfolio, as well as arbitrary
designation of certain other industries by Management.

The general allocation is included in the allowance to cover probable loan
losses within portions of the loan portfolio not addressed in the preceding
allocations. The types of loans included in the general allocation are
residential mortgage loans, direct and indirect consumer loans, credit card
loans and overdrafts. The actual allocation amount is based upon the historical
five-year moving net loss average for each category except for residential
mortgage loans and Somerville. The allocation for residential mortgage loans is
based on a historical five-year net loss average not to be less than a floor
limit of 20 basis points. The allocation for Somerville is based on loss
percentages applied to pools of risk-rated loans within the commercial loan
portfolio. For Somerville's consumer loans, the allocation is based on a
one-year net loan loss estimate.

The amount included in the allocation for lines of credit and letters of credit
consists of a percentage of the unused portion of those lines and the amount
outstanding in letters of credit. Percentages, which are the same as those
applied to the funded portions of the commercial and retail loan portfolios, are
applied to cover any potential losses in these off-balance sheet categories.

As the review of the allowance for loan losses involves a significant degree of
judgment by Management and is imprecise by nature, the unallocated portion
relates to issues that cannot be measured on a quantitative basis over a
prolonged period of time.

ITEM 2. PROPERTIES

Trustmark's principal offices are housed in its complex located in downtown
Jackson, Mississippi and owned by TNB. Approximately 211,000 square feet, or
80%, of the available space in the main office building is allocated to bank use
with the remainder occupied by tenants on a lease basis. Trustmark, through its
two banking subsidiaries, also operates 123 full-service branches, 18
limited-service branches, 4 in-store branches, 4 retirement service branches and
an ATM network which includes 110 ATMs at on-premise locations and 79 ATMs
located at off-premise sites. Trustmark leases 98 of its 212 locations with the
remainder being owned.

ITEM 3. LEGAL PROCEEDINGS

Trustmark and its subsidiaries are parties to lawsuits and other claims that
arise in the ordinary course of business. Some of the lawsuits assert claims
related to the lending, collection, servicing, investment, trust and other
business activities, and some of the lawsuits allege substantial claims for
damages. The cases are being vigorously contested. In the regular course of
business, Management evaluates estimated losses or costs related to litigation,
and provision is made for anticipated losses whenever Management believes that
such losses are probable and can be reasonably estimated. At the present time,
Management believes, based on the advice of legal counsel, that the final
resolution of pending legal proceedings will not have a material impact on
Trustmark's consolidated financial position or results of operations; however,
Management is unable to estimate a range of potential loss on these matters
because of the nature of the legal environment in states where Trustmark
conducts business.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report on Form 10-K, an
evaluation was carried out by Trustmark's management, with the participation of
its Chief Executive Officer and Treasurer (Principal Financial Officer), of the
effectiveness of Trustmark's disclosure controls and procedures (as defined in
Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that
evaluation, the Chief Executive Officer and Principal Financial Officer
concluded that the disclosure controls and procedures were effective as of the
end of the period covered by this report. No changes were made to Trustmark's
internal control over financial reporting (as defined in Rule 13a-15(f) under
the Securities Exchange Act of 1934) during the last fiscal quarter that
materially affected, or are reasonably likely to materially affect Trustmark's
internal control over financial reporting.
Management Report on Internal Control over Financial Reporting

The management of Trustmark Corporation (Trustmark) is responsible for
establishing and maintaining adequate internal control over financial reporting.
Trustmark's internal control over financial reporting was designed under the
supervision of the Chief Executive Officer and Principal Financial Officer to
provide reasonable assurance regarding the reliability of financial reporting
and the preparation of published financial statements in accordance with
generally accepted accounting principles.

Management assessed the effectiveness of internal control over financial
reporting as of December 31, 2004. In making this assessment, it used the
criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO) in Internal Control - Integrated Framework. Based on our
assessment, we believe that, as of December 31, 2004, Trustmark's internal
control over financial reporting is effective based on those criteria.

Trustmark's independent registered public accounting firm, KPMG LLP, has issued
an attestation report on management's assessment of the effectiveness of
Trustmark's internal control over financial reporting as of December 31, 2004.
The report, which expresses unqualified opinions on management's assessment and
on the effectiveness of Trustmark's internal control over financial reporting as
of December 31, 2004, can be found in the "Report of Independent Registered
Public Accounting Firm" included in Trustmark's 2004 Annual Report to
Shareholders and is incorporated herein by reference.
