                                     PART I

ITEM 1.  BUSINESS

GENERAL

Trustmark Corporation  (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
Mississippi and Tennessee.

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  its  three   wholly-owned
subsidiaries,  Trustmark Financial Services,  Inc. (TFSI),  Trustmark Investment
Advisors, Inc. (TIA) and The Bottrell Insurance Agency, Inc. (Bottrell).

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, 2002, Trustmark and
its subsidiaries employed 2,443 full-time equivalent employees.

Trustmark  engages in business  through  its four  reportable  segments:  Retail
Banking, Commercial Banking, Financial Services and Treasury & Other. The Retail
Banking  division  provides  banking  services to individuals and small business
customers.  The Commercial Banking division services corporate and middle-market
clients.  Financial Services offers a full range of services to meet specialized
financial  needs of both  individuals  and corporate  clients.  Treasury & Other
consists of internal operations,  such as asset/liability  management activities
including  the  investment  portfolio and the related  gains/losses  on sales of
securities, as well as credit risk management, bank operations, human resources,
marketing and the controller's department.

Retail Banking

Retail  Banking  provides a full range of  financial  products  and  services to
individuals  and small business  customers  through  Trustmark's  138 offices in
Mississippi  and  Tennessee.  During 2002,  Trustmark  continued to evaluate its
major retail  markets in an effort to  effectively  position its branch  network
within each market. During the year, four offices were renovated,  eight offices
were closed and two new offices were opened.

During 2002,  Trustmark  continued to apply  technology,  innovation and expense
control  to  improve  productivity  and  assist in  managing  profitability  and
customer relationships.  One primary example of the integration of these factors
was the Credit  Process  Redesign  initiative  used to evaluate  and improve the
consumer and business credit  processes.  The goal of this process was to create
an environment that fosters greater customer satisfaction, generates loan growth
and improves  efficiency while maintaining  solid credit quality.  This process,
facilitated  by a  nationally  recognized  management  consulting  firm,  should
streamline  workflow,  eliminate  processing  delays and  result in timely  loan
decisions for Trustmark's customers.

Significant efforts were also devoted to developing a check image archive.  This
archive,  scheduled  to be  deployed  during  the second  quarter of 2003,  will
improve research  efficiency and increase  customer  satisfaction.  It will also
position  Trustmark  to  provide  additional   revenue-generating  services  for
consumer and commercial relationships.

Customers may access automated teller machines (ATM) through Trustmark's network
of 179 ATMs in 155  locations  in  Mississippi  and  Tennessee,  in  addition to
worldwide  access  through  other ATM networks  such as Plus,  Pulse and Cirrus.
TrustTouch services allow customers to access detailed account information,  via
a toll free number 24 hours a day, and TrustTouchpc services offer customers the
flexibility  to access  account  information  as well as the  ability to process
transactions  24 hours a day via  computer.  TrustTouchWeb  allows  customers to
access their bank accounts from any  Internet-equipped  computer.  TrustTouchWeb
gives  instant  access  to  secured  account  information  around-the-clock  and
provides  the ability to pay bills  electronically  and transfer  funds  between
accounts.  TrustNetWeb,  our  Internet  banking  product for small to  mid-sized
businesses,  provides the same convenience and flexibility as TrustTouchWeb with
additional features tailored specifically for businesses.


Trustmark  provides Retail Banking customers with various personal loan products
and small  business  loans.  Trustmark  also lends to moderate  and lower income
homeowners  through Community  Reinvestment Act programs such as the Downpayment
Assistance Program and Farmers Home Multi-Family Home Program.

Trustmark  continues  to serve small  businesses  through the  Business  Banking
group, which provides banking,  investment and insurance solutions to businesses
with annual  sales of up to $3 million.  The Bank at Work  program  serves as an
alternative   delivery   channel  that  provides  banking  services  on-site  to
businesses employing over 100 people.

Commercial Banking

Commercial Banking provides various financial products and services to corporate
and  middle-market  clients through TNB's  Commercial  Lending,  Commercial Real
Estate,  Indirect  Lending and Private  Banking  groups.  Business  Advantage is
designed  to give  businesses  a total  package of business  savings,  financial
management and convenient services in one comprehensive  package,  when combined
with a regular commercial or small business checking account. To better meet the
unique  credit needs of larger  businesses,  the  Commercial  Lending  group has
created relationship  managers to work primarily with local middle-market firms,
specialized industries,  as well as large regional and national firms. Trustmark
continues to be active in automobile financing directly through long-established
relationships with automobile dealers.

Financial Services

Financial Services includes trust and fiduciary  services,  brokerage  services,
insurance  services,  as well as credit card and  mortgage  services.  With $6.6
billion in assets under  administration,  Trustmark  offers a full line of asset
management and custodial  services through its Personal Trust,  Employee Benefit
and Corporate  Trust groups.  The Wealth  Management  Group provides  customized
solutions for affluent customers by integrating  investment  management,  estate
planning, insurance products and private banking.

Trustmark's   Correspondent  Banking  Department  maintains  relationships  with
independent  banks  across  the  state,  providing   competitively  priced  cash
management, financing and clearing services. Trustmark's public services bankers
offer cash management  products,  loans and investment services tailored for the
needs of public  entities  such as state  agencies,  municipal  governments  and
school districts.

Included in Financial  Services is Trustmark's  proprietary  mutual fund family,
The  Performance  Funds.  The six  mutual  funds are  designed  and  managed  by
Trustmark  Investment   Advisors'  investment   professionals  and  are  offered
throughout  the  financial  services  division,  including  Trustmark  Financial
Services, Inc., TNB's full service brokerage subsidiary.

Through Bottrell, TNB's insurance subsidiary, Trustmark provides a full range of
commercial  insurance  products as well as personal life,  health,  property and
casualty  insurance.  During  2002,  Bottrell  was able  expand its  products to
include school,  medical  malpractice and mid-market  business insurance through
the acquisition of Chandler-Sampson Insurance, Inc.

Treasury & Other

Treasury  & Other  consists  of  internal  operations,  such as  asset/liability
management  activities  including TNB's investment  portfolio  and  the  related
gains/losses  on sales of securities,  as well as credit risk  management,  bank
operations, human resources, marketing and the controller's department.

Additional information on Trustmark's segments can be found in Note 18, "Segment
Information,"  (pages  39-41)  included in  Trustmark's  2002  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
Act as soon as  reasonably  practicable  after such  material is  electronically
filed, or furnished to, the Securities and Exchange Commission (SEC).


Business Combinations

In June 2002, The Bottrell Insurance Agency, Inc., a wholly-owned  subsidiary of
TNB,  acquired  Chandler-Sampson  Insurance,  Inc.  (CSI)  located  in  Jackson,
Mississippi.  CSI was a  regional  leader in  school,  medical  malpractice  and
mid-market  business insurance and had total assets of approximately $2 million.
This business  combination,  which was not material to Trustmark,  was accounted
for under the purchase method of accounting.

Forward-looking Statements

Certain statements contained in Trustmark's Management's Discussion and Analysis
of  Financial  Condition  and  Results  of  Operations  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.  Words such as
"expects," "anticipates,"  "believes," "estimates" and other similar expressions
are intended to identify these forward-looking  statements. Such forward-looking
statements are subject to certain risks,  uncertainties and assumptions.  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
         declining  interest  rate  environment  will have an impact on the fair
         value of the mortgage  servicing  portfolio which can 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.  These statements are representative only
as of the date hereof,  and Trustmark  does not assume any  obligation to update
these  forward-looking  statements  or to update the reasons why actual  results
could differ from those projected in the forward-looking statements.

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. TFSI, TNB's full service brokerage  subsidiary,  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 is subject to the
insurance laws and regulations of the states in which it is 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, in
2001 TNB elected for Bottrell to become a financial subsidiary. This enables TNB
to engage in  insurance  agency  activities,  through its  financial  subsidiary
Bottrell, 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.

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, 2002,  Trustmark  exceeded both  requirements  with Tier 1 capital and total
capital  equal  to  12.74%  and  13.99%  of  its  total  risk-weighted   assets,
respectively.  At December 31, 2002,  TNB also exceeded both  requirements  with
Tier 1  capital  and  total  capital  equal to  12.61%  and  13.86% 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,  2002,  the
leverage ratios for Trustmark and TNB were 8.72% and 8.64%, 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, 2002, 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.  During the fourth  quarter of 2002,  TNB
applied for and  received  approval  from its  regulators  to pay an  additional
$100.0  million in  dividends  to  continue  the  capital  management  plan,  as
discussed  in Note 14,  "Shareholders'  Equity,"  included in  Trustmark's  2002
Annual Report to  Shareholders.  TNB will have  available in 2003  approximately
$33.7  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, 2002,  TNB's annual BIF and
SAIF assessment rates and Somerville's BIF rate were $0.0168 per $100 of insured
deposits.

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 1.99 years.

As of December 31, 2002,  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  if:  (1) the  loan is  maintained  on a cash  basis  because  of a
deterioration in the financial condition of the borrower, (2) payment in full of
the principal and interest is not expected or (3) principal or interest has been
in default for a period of 90 days or more unless the loan is both well  secured
and in the process of  collection.  When a loan is placed in nonaccrual  status,
unpaid  interest  credited  to income in the current and prior years is reversed
against  interest  income.  Interest  received  on  nonaccrual  loans is applied
against principal.  Generally,  loans may be restored to accrual status when (1)
none of the  principal  and  interest  is due and  unpaid  and the bank  expects
repayment of the  remaining  contractual  principal  and interest or (2) when it
otherwise  becomes  well  secured  and in the process of  collection.  Loans are
generally  measured  for  impairment  based on the  present  value of the loan's
effective  interest rate,  except when foreclosure or liquidation is probable or
when the primary source of repayment is provided by real estate collateral.  The
policy  for  recognizing  income  on  impaired  loans  is  consistent  with  the
nonaccrual policy.

As of December  31, 2002,  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  2002  can be  found  in  the  table  captioned
"Nonperforming  Assets" and the  related  discussion  (page 56)  included in the
Registrant's  2002 Annual Report to Shareholders  and is incorporated  herein by

The  allowance for loan losses is  maintained  at a level  believed  adequate by
Management  to absorb  estimated  probable  loan losses.  Management's  periodic
evaluation  of the  adequacy  of the  allowance  is  based  on  identified  loan
impairments, Trustmark's past loan loss expericence, known and inherent risks in
the portfolio,  adverse  situations  that may affect the  borrower's  ability to
repay  (including  the timing of future  payments),  the estimated  value of any
underlying  collateral,  composition  of the loan  portfolio,  current  economic
conditions and other relevant factors. 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.


TABLE 10 - ALLOCATION OF THE ALLOWANCE FOR LOAN LOSSES

The following table is a summary by allocation category of Trustmark's allowance
for loan losses at December 31, 2002.  These  allocations  were determined based
upon  Management's  analysis  of the  various  types  of  risk  associated  with
Trustmark's  loan  portfolio.  A  discussion  of  Management's  methodology  for
performing the analysis follows the table ($ in thousands):

Allocation for pools of risk-rated loans                                $38,569
Additional allocation for risk-rated loans                                1,468
Allocation for selected industries                                        5,027
General allocation for all other loans                                   17,717
Allocation for available lines of credit and letters of credit            2,146
Unallocated                                                               9,844
                                                                        -------
  Total                                                                 $74,771
                                                                        =======

The  allowance for loan losses is  maintained  at a level  believed  adequate by
Management  to absorb  probable  losses in the loan  portfolio,  in  addition to
losses associated with off-balance  sheet credit  instruments such as letters of
credit and unfunded  lines of credit.  The adequacy of the allowance is reviewed
monthly utilizing the criteria specified in the Office of the Comptroller of the
Currency's Handbook "Allowance for Loan and Lease Losses", as well as additional
guidance  provided in the Interagency  Policy  Statement.  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 $500,000 or more which are risk-rated as other loans especially
mentioned or substandard  and all which are risk-rated  doubtful are reviewed by
Trustmark's Asset Review  Department staff to determine if standard  percentages
appear to be sufficient to cover probable losses in each category.  In the event
that the percentages on any particular  lines are determined to be insufficient,
additional  allocations are made based upon  recommendations of lending,  credit
and Asset Review Department personnel.

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 more
conservative of either the loss experience  within these  categories  during the
year,  the historical  5-year moving  average for each  category,  or previously
established floors.

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 $9.8 million
relates  to issues  that  cannot be  measured  on a  quantitative  basis  over a
prolonged period of time.

Management  expects that net charge-offs for 2003 should be approximately  0.30%
to 0.35% of average loans as compared with 0.33% for 2002.  Although  Management
believes these  expectations are reasonable,  it can give no assurance that such
expectations will prove to be correct.

ITEM 2. PROPERTIES

Trustmark's  principal  offices  are housed in its  complex  located in downtown
Jackson,  Mississippi  and owned by TNB.  Approximately  212,000 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  114  full-service   branches,  20
limited-service  branches, 4 in-store branches and an ATM network which includes
98 ATMs at  on-premise  locations  and 81 ATMs  located  at  off-premise  sites.
Trustmark leases 72 of its 195 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.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters  submitted to Trustmark's  shareholders  during the fourth

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE

On April 9, 2002, the Board of Directors of Trustmark  Corporation  (Trustmark),
based on the  recommendation  of its Audit  Committee,  decided not to renew the
engagement  of  its  independent   public   accountants,   Arthur  Andersen  LLP
(Andersen).  This determination  followed Trustmark's decision to seek proposals
from other independent  accountants to audit Trustmark's  consolidated financial
statements  for the year ending  December 31, 2002. On April 29, 2002, the Board
of Directors of Trustmark,  based on the  recommendation of its Audit Committee,
announced the engagement of KPMG LLP as its  independent  public  accountants to
replace  Andersen.   Subsequent  to  their  engagement,  KPMG  LLP  audited  the
consolidated balance sheets of Trustmark and its subsidiaries as of December 31,
2002 and 2001,  and the related  consolidated  statements of income,  changes in
shareholders'  equity  and cash  flows for each of the  years in the  three-year
period ended December 31, 2002.

During  Trustmark's  two most recent  fiscal  years and all  subsequent  interim
periods prior to the date hereof, there were no disagreements  between Trustmark
and  Andersen  on any  matter  of  accounting  principles,  financial  statement
disclosure or auditing scope or procedure  which,  if not resolved to Andersen's
satisfaction,  would have caused Andersen to make reference to the matter of the
disagreement in connection with their reports. Andersen's reports on Trustmark's
consolidated financial statements for each of the years ended 2001 and 2000, did
not contain an adverse opinion or disclaimer of opinion, nor were they qualified
or modified as to uncertainty, audit scope or accounting principles.

Andersen's report on Trustmark's consolidated financial statements for the years
ended  December  31,  2001 and 2000,  dated  January 8,  2002,  was issued on an
unqualified basis in conjunction with the filing of Trustmark's Annual Report on
Form 10-K for the year ended December 31, 2001, filed on March 25, 2002.

None of the reportable  events  described under Item  304(a)(1)(v) of Regulation
S-K occurred within  Trustmark's two most recent fiscal years and all subsequent
interim periods prior to the date hereof.

Prior to April 29, 2002,  Trustmark  did not consult with KPMG LLP regarding any
of the matters or events set forth in Item  304(a)(2)(i)  and (ii) of Regulation
S-K.
