                      TRUSTMARK CORPORATION & SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - BASIS OF FINANCIAL STATEMENT PRESENTATION AND PRINCIPLES OF
         CONSOLIDATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in conformity  with  accounting  principles  generally  accepted in the
United  States  of  America  for  interim  financial  information  and  with the
instructions  to  Form  10-Q.  Accordingly,  they  do  not  include  all  of the
information and footnotes required by accounting  principles  generally accepted
in the United  States of  America  for  complete  financial  statements.  In the
opinion of Management, all adjustments (consisting of normal recurring accruals)
considered  necessary for the fair presentation of these consolidated  financial
statements  have been  included.  The notes  included  herein  should be read in
conjunction with the notes to the consolidated  financial statements included in
Trustmark Corporation's (Trustmark) 2002 annual report on Form 10-K.

The consolidated  financial  statements  include  Trustmark and its wholly-owned
bank  subsidiaries,  Trustmark  National Bank (TNB) and Somerville  Bank & Trust
Company  (Somerville).  All  intercompany  accounts and  transactions  have been
eliminated in consolidation.  Certain  reclassifications have been made to prior
period amounts to conform with the current period presentation.

NOTE 2 - BUSINESS COMBINATIONS

On June 18, 2003,  Trustmark and The Banc  Corporation of  Birmingham,  Alabama,
jointly announced the signing of a definitive purchase and assumption  agreement
pursuant  to which TNB will  acquire  seven  Florida  branches  of The  Bank,  a
subsidiary of The Banc Corporation,  for a $46.8 million deposit premium.  These
branches,  known as the Emerald Coast Division, serve the markets from Destin to
Panama City and have loans and deposits of  approximately  $221 million and $205
million, respectively. The transaction, which is subject to regulatory approval,
is expected to be completed during the third quarter of 2003.

On June 28, 2002, The Bottrell Insurance Agency, Inc., a wholly-owned subsidiary
of TNB, acquired Chandler-Sampson Insurance, Inc. (CSI) in Jackson, Mississippi.
This business combination, which is not material to Trustmark, was accounted for
under the purchase  method of accounting.  The  shareholders  of CSI received $8
million in cash in  connection  with the merger.  Excess cost over  tangible net
assets  acquired  totaled $10  million,  of which $3 million and $7 million have
been   allocated  to  other   identifiable   intangible   assets  and  goodwill,
respectively. Trustmark's financial statements include the results of operations
for the CSI  acquisition  from the  merger  date.  The pro forma  impact of this
acquisition on Trustmark's results of operations is insignificant.

NOTE 3 - ALLOWANCE FOR LOAN LOSSES

The following table summarizes the activity in the allowance for loan losses for
the six-month periods ended June 30 ($ in thousands):

                                                         ========      ========

At June 30, 2003 and 2002, the carrying  amounts of nonaccrual  loans were $28.9
million and $41.1 million,  respectively.  Included in these nonaccrual loans at
June 30, 2003 and 2002,  are loans that are  considered  to be  impaired,  which
totaled $21.7 million and $33.3  million,  respectively.  At June 30, 2003,  the
total  allowance  for loan  losses  related to impaired  loans was $5.5  million
compared  with $8.1 million at June 30, 2002.  The average  carrying  amounts of
impaired loans during the second quarter of 2003 and 2002 were $21.8 million and
$33.6  million,  respectively.  No  material  amounts of  interest  income  were
recognized on impaired loans or nonaccrual  loans for the second quarter of 2003
or 2002.

NOTE 5 - STOCK-BASED COMPENSATION

Prior to January 1, 2003,  Trustmark accounted for incentive stock options under
the recognition and measurement  provisions of Accounting Principles Board (APB)
Opinion No. 25,  "Accounting  for Stock Issued to Employees."  Under APB No. 25,
because the exercise price of Trustmark's stock options equaled the market price
for the  underlying  stock on the date of grant,  no  compensation  expense  was
recognized.  Effective  January  1,  2003,  Trustmark  adopted  the  fair  value
recognition provisions of Statement of Financial Accounting Standards (SFAS) No.
123,  "Accounting  for  Stock-Based  Compensation,"  as amended by SFAS No. 148,
"Accounting for Stock-Based Compensation - Transition and Disclosure." Under the
provisions  of these  statements,  Trustmark  will account for  incentive  stock
options prospectively for all awards granted,  modified or settled after January
1, 2003.  The  following  table  reflects  pro forma net income and earnings per
share for the periods  presented,  had Trustmark elected to adopt the fair value
approach for all  outstanding  options  prior to January 1, 2003 ($ in thousands

Trustmark  issues  financial and  performance  standby  letters of credit in the
normal  course  of  business  in order to  fulfill  the  financing  needs of its
customers.  Standby  letters of credit  are  conditional  commitments  issued by
Trustmark to insure the  performance of a customer to a third party. A financial
standby  letter of credit is a commitment by Trustmark to guarantee a customer's
repayment of an  outstanding  loan or debt  instrument.  Trustmark  guarantees a
customer's  performance  to a  third  party  under  a  contractual  nonfinancial



obligation  through  the use of a  performance  standby  letter of credit.  When
issuing  letters  of  credit,  Trustmark  uses  essentially  the  same  policies
regarding credit risk and collateral which are followed in the lending process.

At June 30, 2003,  the maximum  potential  amount of future  payments  Trustmark
could be required to make under its standby letters of credit was $70.3 million,
which  also   represented   the  maximum  credit  risk   associated  with  these
commitments.  This amount consisted  primarily of commitments with maturities of
less than four  years.  These  standby  letters  of  credit  have an  immaterial
carrying value.  Trustmark holds collateral to support standby letters of credit
when deemed  necessary.  As of June 30, 2003, the fair value of collateral  held
was $23.2 million.

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  and  Management's
evaluation, that the final resolution of pending legal proceedings will not have
a material impact on Trustmark's  consolidated  financial position or results of
operations.

NOTE 7 - EARNINGS PER SHARE

Basic  earnings  per share  (EPS) is  computed  by  dividing  net  income by the
weighted average shares of common stock outstanding.  Diluted EPS is computed by
dividing net income by the weighted average shares of common stock  outstanding,
adjusted for the effect of partially  diluted stock options  outstanding  during
the  period.  The  following  table  reflects  weighted  average  shares used to
calculate basic and diluted EPS for the periods presented:

NOTE 8 - STATEMENTS OF CASH FLOWS

Trustmark paid income taxes approximating $30.2 million and $15.0 million during
the six months  ended June 30,  2003 and 2002,  respectively.  Interest  paid on
deposit liabilities and other borrowings approximated $48.3 million in the first
six months of 2003 and $62.8  million  in the first six months of 2002.  For the
six  months  ended  June 30,  2003 and 2002,  noncash  transfers  from  loans to
foreclosed properties were $2.9 million and $3.4 million, respectively.

NOTE 9 - RECENT PRONOUNCEMENTS

In May 2003,  the Financial  Accounting  Standards  Board (FASB) issued SFAS No.
150, "Accounting for Certain Financial  Instruments with Characteristics of both
Liabilities and Equity." This statement  establishes standards for how an issuer
classifies and measures certain financial  instruments with  characteristics  of
both  liabilities  and equity.  The  statement  applies to three  categories  of
freestanding   financial   instruments:   1)  certain   mandatorily   redeemable
instruments,  2) instruments with repurchase obligations and 3) instruments with
obligations to issue a variable  number of shares.  The statement  requires that
previously  issued  instruments that fall within the scope of the statement must
be reclassified as liabilities,  and subsequent  changes in the  measurements of
the  instruments  treated  as  liabilities  must  flow  through  to  the  income
statement.  For  public  companies,  this  statement  became  effective  for all
freestanding  financial instruments entered into or modified after May 31, 2003.
Otherwise it becomes  effective at the  beginning  of the first  interim  period
beginning after June 15, 2003. Currently,  Trustmark does not have any financial
instruments within the scope of this statement.


In April 2003,  the FASB issued SFAS No. 149,  "Amendment  of  Statement  133 on
Derivative  Instruments  and  Hedging  Activities."  This  statement  amends and
clarifies  financial  accounting  and  reporting  for  derivative   instruments,
including   certain   derivative   instruments   embedded  in  other   contracts
(collectively  referred to as derivatives) and for hedging activities under SFAS
No. 133,  "Accounting for Derivative  Instruments and Hedging  Activities." This
statement is effective  for  contracts  entered into or modified  after June 30,
2003, and for hedging relationships  designated after June 30, 2003. The effects
of this  statement did not have a material  impact on  Trustmark's  consolidated
financial position or results of operations upon adoption on June 30, 2003.

NOTE 10 - SEGMENT INFORMATION

Effective  January 1, 2003,  Trustmark changed the composition of its reportable
segments to the following:  Consumer Division,  Commercial Division,  Investment
Division and Operations Division. The Consumer Division delivers a full range of
banking, investment and risk management products and services to individuals and
small businesses through Trustmark's extensive branch network.  Included in this
segment are products and services for insurance, credit card, mortgage, indirect
automobile financing and student loans. The Commercial Division provides various
financial products and services to corporate and middle-market clients. Included
among these  products and services are  specialized  services for commercial and
residential real estate development lending as well as other specialized lending
services.  The  Investment  Division  includes  trust  and  fiduciary  services,
discount  brokerage  services  and services for private  banking  clients.  Also
included  in this  segment is a  selection  of  investment  management  services
including  Trustmark's  proprietary mutual fund family. The Operations  Division
consists of  asset/liability  management  activities that include the investment
portfolio and the related gains/losses on sales of securities, as well as credit
risk  management,   bank  operations,   human  resources  and  the  controller's
department.  The  Operations  Division also includes  expenses such as corporate
overhead and amortization of intangible assets.

Trustmark  evaluates  performance and allocates resources based on the profit or
loss of the individual  segments.  Trustmark  utilizes matched maturity transfer
pricing to assign cost of funding to assets and earnings  credits to liabilities
with a  corresponding  offset to the Operations  Division.  Trustmark  allocates
noninterest  expense  based  on  various   activity-based   costing  statistics.
Excluding internal funding,  Trustmark does not have  inter-company  revenues or
expenses.  Additionally,  segment  income tax  expense is  calculated  using the
marginal tax rate. The difference between the marginal and effective tax rate is
included in the Operations Division.

The tables on pages 11 and 12 disclose financial  information,  by segment,  for
the  periods  ended  June 30,  2003 and 2002.  The prior  year  period  has been
restated to conform to the current presentation.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
            AND RESULTS OF OPERATIONS

The  following  provides  a  narrative  discussion  and  analysis  of  Trustmark
Corporation's  (Trustmark)  financial condition and results of operations.  This
discussion  should  be read  in  conjunction  with  the  consolidated  financial
statements  and the  supplemental  financial  data  included  elsewhere  in this
report.

BUSINESS

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.  Initially  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  three  wholly-owned
subsidiaries, Trustmark Financial Services, Inc., Trustmark Investment Advisors,
Inc. and The Bottrell Insurance Agency, Inc.

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 June 30, 2003, Trustmark and its
subsidiaries employed 2,286 full-time equivalent employees.

Trustmark  engages in business  through its four reportable  segments:  Consumer
Division,  Commercial Division, Investment Division and Operations Division. The
Consumer  Division  delivers  a full  range  of  banking,  investment  and  risk
management  products and services to individuals  and small  businesses  through
Trustmark's  extensive branch network.  The Commercial Division provides various
financial  products and services to corporate  and  middle-market  clients.  The
Investment  Division includes trust and fiduciary  services,  discount brokerage
services and services  for private  banking  clients.  The  Operations  Division
consists of  asset/liability  management  activities that include the investment
portfolio and the related gains/losses on sales of securities, as well as credit
risk  management,   bank  operations,   human  resources  and  the  controller's
department.

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  collectibility
         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.

CRITICAL ACCOUNTING POLICIES

Trustmark's  consolidated  financial  statements are prepared in accordance with
accounting principles generally accepted in the United States of America,  which
require the use of estimates and assumptions that affect the amounts reported in
those consolidated  financial statements.  The following is a description of the
accounting  policies applied by Trustmark which are deemed "critical."  Critical
accounting  policies are defined as policies that are important to the portrayal
of  Trustmark's  financial  condition and results of operations and that require
Management's most difficult,  subjective or complex judgments.  Actual financial
results  could  differ  significantly  if different  judgments or estimates  are
applied in the application of these policies.

Allowance for Loan Losses
The allowance for loan losses is maintained at a level  Management and the Board
of Directors believe is adequate to absorb estimated  probable losses within the
loan portfolio.  A formal analysis is prepared monthly to assess the risk in the
loan  portfolio  and to determine the adequacy of the allowance for loan losses.
The analysis for loan losses  considers  any  identified  impairment  as well as
estimates which have been determined by applying  specific  allowance factors to
the commercial and consumer loan portfolios.

Commercial  loans as well as  commercial  real estate loans carry an  internally
assigned  risk  grade  based on a scale of one to ten.  An  allowance  factor is
assigned to each loan grade based on historical loan losses in addition to other
factors such as the level and trend of delinquencies,  classified and criticized
loans and nonperforming  loans.  Other factors are also taken into consideration
such as local,  regional and national economic trends,  industry and other types
of concentrations and loan loss trends that run counter to historical  averages.
All  classified  loans greater than $500 thousand are reviewed  quarterly by the
Asset Review  Department  to determine if a higher  allowance  factor  should be
applied to the loan based on a greater level of risk and probability of loss.

Consumer loans carry  allowance  factors  applied to pools of homogeneous  loans
such as direct and indirect loans,  credit cards, home equity loans, other types
of  revolving  consumer  lines of credit and  residential  mortgage  loans.  The
allowance factor applied to each pool is based on historical loan loss trends as
well  as  current  and  projected  trends  in  loan  losses.   Also  taken  into
consideration are trends in consumer  delinquencies,  consumer  bankruptcies and
the  effectiveness  of  Trustmark's  collection  function  as well  as  economic
conditions and trends referred to above.

Mortgage Servicing Rights
Mortgage  servicing  rights  are rights to service  mortgage  loans for  others,
whether the loans were acquired through purchase or loan origination.  Purchased
mortgage servicing rights are capitalized at cost. For loans originated and sold
where the servicing rights have been retained,  Trustmark  allocates the cost of
the loan  and the  servicing  right  based on their  relative  fair  values.  In
determining the fair value of mortgage  servicing  rights,  Trustmark  relies on
assumptions  regarding factors such as mortgage interest rates,  discount rates,
mortgage loan prepayment speeds,  market trends and industry demands. Any change
in these assumptions  could produce different fair values of mortgage  servicing
rights.  Impairment, if any, for mortgage servicing rights is recognized through
a valuation allowance with a corresponding charge to noninterest expense that is
determined using estimated fair values with the loans stratified by product type
and term. As of June 30, 2003,  mortgage  servicing  rights had a gross carrying
amount of $60.1  million  with a valuation  allowance  of $22.4  million.  As of
year-end 2002,  mortgage  servicing  rights had a gross carrying amount of $61.3
million with a valuation allowance of $12.5 million.


Fair Values
Determining the fair value of net assets acquired through business combinations,
including  the  recognition  of  intangible  assets,  involves a high  degree of
judgment  and  complexity.  Certain  assets,  such as loans  held for sale,  are
accounted  for at the lower of cost or fair value.  Some of these  assets do not
have readily available market quotations and require an estimation of their fair
value. Additionally,  certain recorded assets, such as goodwill and core deposit
intangibles,  are subject to periodic impairment analysis.  As of June 30, 2003,
Trustmark had unamortized goodwill totaling $48.0 million and other identifiable
intangible  assets  subject  to  amortization  totaling  $21.1  million.   These
intangible assets are evaluated for impairment periodically. Impairment, if any,
for  goodwill  and other  identifiable  intangible  assets  would be  charged to
noninterest expense.

BUSINESS COMBINATIONS

On June 18, 2003,  Trustmark and The Banc  Corporation of  Birmingham,  Alabama,
jointly announced the signing of a definitive purchase and assumption  agreement
pursuant  to which TNB will  acquire  seven  Florida  branches  of The  Bank,  a
subsidiary of The Banc Corporation,  for a $46.8 million deposit premium.  These
branches,  known as the Emerald Coast Division, serve the markets from Destin to
Panama City and have loans and deposits of  approximately  $221 million and $205
million, respectively. The transaction, which is subject to regulatory approval,
is expected to be completed during the third quarter of 2003.

On June 28, 2002, The Bottrell Insurance Agency, Inc., a wholly-owned subsidiary
of TNB, acquired Chandler-Sampson Insurance, Inc. (CSI) in Jackson, Mississippi.
This business combination, which is not material to Trustmark, was accounted for
under the purchase  method of accounting.  The  shareholders  of CSI received $8
million in cash in  connection  with the merger.  Excess cost over  tangible net
assets  acquired  totaled $10  million,  of which $3 million and $7 million have
been   allocated  to  other   identifiable   intangible   assets  and  goodwill,
respectively. Trustmark's financial statements include the results of operations
for the CSI  acquisition  from the  merger  date.  The pro forma  impact of this
acquisition on Trustmark's results of operations is insignificant.

FINANCIAL SUMMARY HIGHLIGHTS

Basic  earnings  per  share  was $0.53 for the  second  quarter  of 2003,  which
represents a 6.0% increase compared to $0.50 for the second quarter of 2002. Net
income for the second quarter of 2003 totaled $31.2  million,  compared to $31.4
million for the prior year period, and resulted in a return on average assets of
1.70% and a return on average equity of 18.76%. Basic earnings per share for the
six  months  ended  June  30,  2003,  was  $0.94  compared  to $0.98  for  2002.
Trustmark's  net  income  for the  first  half of 2003  totaled  $55.6  million,
compared to $61.7 million for the prior year period, and resulted in a return on
average  assets of 1.55%  and a return on  average  equity of  16.83%.  Earnings
during the first quarter of 2003  included an after-tax  charge of $4.1 million,
or $0.07 per share,  associated  with  Trustmark's  voluntary  early  retirement
program.  At June 30, 2003,  Trustmark  reported total loans of $4.826  billion,
total  assets  of  $7.373   billion,   total  deposits  of  $4.967  billion  and
shareholders' equity of $664.4 million.

RESULTS OF OPERATIONS

Net Interest Income
Net interest income is the principal  component of Trustmark's income stream and
represents the difference,  or spread, between interest and fee income generated
from  earning  assets and the  interest  expense  paid on deposits  and borrowed
funds.  Fluctuations  in  interest  rates as well as volume  and mix  changes in
earning  assets  and  interest-bearing  liabilities  can  materially  impact net
interest  income.  The net interest  margin (NIM) is computed by dividing  fully
taxable  equivalent net interest income by average  interest-earning  assets and
measures  how  effectively  Trustmark  utilizes its  interest-earning  assets in
relationship  to the interest  cost of funding  them.  The  Yield/Rate  Analysis
Tables  on  pages  17 and 18  show  the  average  balances  for all  assets  and
liabilities  of Trustmark  and the interest  income or expense  associated  with
earning assets and interest-bearing  liabilities. The yields and rates have been
computed  based upon  interest  income and expense  adjusted to a fully  taxable
equivalent  (FTE) basis using a 35%  federal  marginal  tax rate for all periods
shown.  Nonaccruing  loans have been  included in the average loan  balances and
interest  collected  prior to these loans having been placed on  nonaccrual  has
been included in interest income. Loan fees included in interest associated with
the average loan balances are immaterial.


As  interest  rates  remain at  historically  low  levels,  Management  has been
challenged  to position  the balance  sheet to mitigate the  compression  of net
interest  income.  Funds  provided  from  maturities,   paydowns  and  sales  of
securities  have been used to fund  loan  growth  and  purchases  of  additional
securities  to maintain  sufficient  levels of earning  assets.  Trustmark  also
reduced interest expense on FHLB advances by engaging in various swap agreements
during the second quarter of 2003. Trustmark will continue to manage the overall
risk exposure present during significant  movements in interest rates and reduce
the impact of interest  rate  movement on net interest  income.  For  additional
discussion, see Market/Interest Rate Risk Management beginning on page 27.

Net interest income-FTE for the three-month and six-month periods ended June 30,
2003, decreased $6.8 million, or 8.9%, and $11.7 million, or 7.7%, respectively,
compared to figures one year earlier.  The continuing  decline in interest rates
experienced  during  2003 and 2002 has  impacted  both  assets and  liabilities.
Earning asset yields declined at a faster rate than  interest-bearing  liability
rates,  resulting  in declines in the NIM of 81 basis points and 64 basis points
when comparing the three-month  and six-month  periods ended June 30, 2003, with
the same periods in 2002.

Average  interest-earning assets for the first half of 2003 were $6.583 billion,
compared  with $6.213  billion for the first half of 2002, an increase of $370.0
million,  or 6.0%.  This  growth  is  primarily  seen in  average  loans,  which
increased  4.5% during first six months of 2003 from the same period in 2002, as
Trustmark  effectively  utilized the liquidity from maturing  securities to fund
loan growth,  which yielded higher returns than  securities  during this period.
However,  yields have been  negatively  impacted by the declining  interest rate
environment as the yield on average earning assets dropped from 6.91% during the
first six months of 2002 to 5.79% for the same period in 2003, a decrease of 112
basis points. As a result,  interest  income-FTE  decreased by $24.1 million, or
11.3%, during the first half of 2003 when compared with the prior year period.

- --------------------------------------------------------------------------------

Average  interest-bearing  liabilities  for the six months  ended June 30,  2003
totaled $5.309 billion,  compared with $5.048 billion for the prior year period,
an  increase  of $261.0  million,  or 5.2%.  Average  interest-bearing  deposits
increased,  as  well as  federal  funds  purchased,  repurchase  agreements  and
borrowings.  Although  interest-bearing  liabilities  have  increased,  interest
expense  has  continued  to  decrease  due  to  the   declining   interest  rate
environment. The average rates on interest-bearing liabilities for the first six
months of 2003 and 2002,  were 1.80% and 2.38%,  respectively,  a decrease of 58
basis points. As a result of these factors, total interest expense for the first
half of 2003 decreased $12.3 million,  or 20.7%, when compared with figures from
the prior year.


Trustmark's use of derivative financial instruments  positively impacted the NIM
in both  2002 and  2003.  Interest  rate  contracts  provided  $1.3  million  of
additional  interest  income as the floor  reached its strike price during first
half of 2002. During the second quarter of 2003,  Trustmark  implemented the use
of swap agreements and reduced interest expense by $218 thousand. For additional
discussion, see Market/ Interest Rate Risk Management beginning on page 27.

Provision for Loan Losses
Trustmark's  provision  for loan losses  totaled $2.6 million and $5.6  million,
respectively,  for the three- month and  six-month  periods ended June 30, 2003,
compared with $3.0 million and $7.3 million,  respectively, for the same periods
in 2002. As a percentage of average loans, the provision was 0.24% for the first
half of 2003  compared  with 0.33% for the prior year period.  The provision for
loan losses  reflects  Management's  assessment of the adequacy of the allowance
for loan losses to absorb probable  losses  inherent in the loan portfolio.  The
amount of  provision  for each period is dependent  upon many factors  including
loan growth, net charge-offs,  changes in the composition of the loan portfolio,
delinquencies,  Management's  assessment of loan portfolio quality, the value of
collateral and general economic factors. See further discussion of the Allowance
for Loan Losses in Critical Accounting Policies beginning on page 14, as well as
the discussion of Loans and Allowance for Loan Losses beginning on page 25.

Noninterest Income
Noninterest  income (NII)  consists of revenues  generated from a broad range of
banking and  financial  services.  NII totaled  $83.3  million for the first six
months of 2003,  an increase  of $23.6  million,  or 39.6%,  from the prior year
period. NII represented 31.1% of total revenues in the six months ended June 30,
2003,  versus 22.3% in the first half of 2002.  The  comparative  components  of
noninterest  income for the six-month  periods ended June 30, 2003 and 2002, are
shown in the accompanying table on page 20.

The single  largest  component  of  noninterest  income  continues to be service
charges for deposit  products and services,  which  increased  8.1% in the first
half of 2003 over the prior year period.  This increase was primarily the result
of courtesy overdraft protection,  which was introduced during the third quarter
of 2002, as well as from increased transaction volume.

Other account  charges and fees totaled $13.8 million in the first half of 2003,
a decrease of $443 thousand,  or 3.1%, when compared with the prior year period.
Decreasing  revenues from market driven  products was the primary factor in this
decline  as  reductions  were  seen  in  brokerage  and  advisory  services  and
float-related revenues. Offsetting this decrease were increases in bankcard fees
from the repricing of merchant  discount rates and increased debit card usage by
individuals.

Insurance  commissions  were $8.8  million  for the  first  six  months of 2003,
compared to $6.5 million in the first half of 2002, an increase of $2.3 million,
or 35.2%.  This growth was primarily from the Chandler  Sampson  Insurance (CSI)
business  combination,  which  was  completed  on  June  28,  2002,  as  well as
intensified sales efforts and increased pricing by insurance companies.

During the six months ended June 30, 2003,  mortgage servicing fees totaled $8.6
million, maintaining the level from the prior year period. Increased prepayments
during the period slowed the overall growth of the mortgage servicing portfolio.
Trustmark  serviced  mortgage loans with average balances of $3.4 billion in the
first half of 2003 and $3.6 billion in the prior year period.

Trust  service  income  was $4.7  million  for the first six  months of 2003,  a
decrease of $354 thousand when compared with the prior year period, as continued
weakness  in  capital  markets  slowed  growth in this  area.  Trustmark,  which
continues  to be one of the largest  providers of asset  management  services in
Mississippi, held assets under administration of $7.1 billion at June 30, 2003.

Gains on sales of loans were $9.1 million in the six months ended June 30, 2003,
compared with $3.7 million in the prior year period.  During the second  quarter
of 2003,  Trustmark sold $63 million of its student loan portfolio for a gain of
$1.8 million.  Intermittently,  Trustmark  sells  delinquent GNMA loans from its
servicing  portfolio,  which allows  Trustmark to  eliminate  costly  collection
efforts.  Trustmark  has recorded  gains of $2.4 million from these sales in the
first  half of 2003,  compared  with $507  thousand  in the prior  year  period.
Excluding  the impact of these  specific  transactions,  gains on sales of loans
from  secondary  marketing  activity  experienced  volume-driven  growth of $1.7
million  during the first six months of 2003  compared  with the same  period in
2002 from an  increased  volume  of  branch-originated  loans and the  continued
benefit of a falling interest rate environment.

Securities  gains totaled $12.2 million during the first half of 2003,  compared
with $516 thousand during the first half of 2002. During the first six months of
2003,  significant  price changes in certain  available for sale (AFS) portfolio
securities  enabled  Trustmark  to sell  securities  with a total  fair value of
$288.1  million,  which provided the opportunity to restructure a portion of the
portfolio to reduce price  volatility  in an extremely  low interest rate cycle.
Management  considers  the  investment  portfolio  as an  integral  tool  in the
management of interest rate risk.

During the six-month period ended June 30, 2003, other income was $477 thousand,
a $3.2 million  increase from the $2.7 million loss recognized in the prior year
period.  Valuation  adjustments on Trustmark's interest rate caps and floors had
the  greatest  impact on other  income,  with losses of $628  thousand  and $2.9
million for the first six months of 2003 and 2002,  respectively.  Although  the
intent  of  interest  rate  caps and  floors is to  provide  protection  against
excessive  interest rate movement over a period of years that may be detrimental
to  Trustmark's  earnings,  fair value  accounting  is used to carry  derivative
financial  instruments with changes in value recognized currently in earnings as
other income. These noncash charges against income may be reversed,  in whole or
in part, if interest rates increase prior to the expiration of the interest rate
caps currently held by Trustmark,  which expire in 2006. The fair value of these
interest rate  contracts was $102 thousand and $8.1 million at June 30, 2003 and
2002, respectively.

Noninterest Expense
Trustmark's  noninterest expense increased $24.0 million, or 22.7%, in the first
six months of 2003 to $129.7 million,  compared with $105.7 million in the first
half of 2002.  This increase is primarily seen in two  categories,  salaries and
employee  benefits  and   amortization/impairment   of  intangible  assets.  The
comparative  components of noninterest expense for the six months ended June 30,
2003 and 2002, are shown in the accompanying table.

- --------------------------------------------------------------------------------

Salaries and employee  benefits,  the largest  category of noninterest  expense,
were $65.4 million in the first half of 2003 and $58.5 million in the prior year
period,  an increase of $7.0 million,  or 11.9%. This increase is primarily from
$6.3 million of expense  recognized for Trustmark's  early  retirement  program.
This program was accepted by 116 employees,  or 4.75% of the  workforce,  and is
expected to result in significant  savings  during the remainder of 2003.  These
savings should also enhance earnings in 2004.


Amortization/impairment  expense associated with intangible assets totaled $20.4
million for the first half of 2003, compared with $3.8 million in the prior year
period.  The increase  experienced  during the 2003 period included $9.9 million
for  additional  impairment of mortgage  servicing  rights  compared with a $2.0
million  impairment  reversal  in the prior  period.  Growth  in the  impairment
allowance results from the continued  reduction in long-term  mortgage rates and
the related  increase in  prepayments  of mortgage  loans,  which had a negative
impact on the fair  value of  Trustmark's  mortgage  servicing  portfolio.  This
charge against income may be reversed, in whole or in part, if refinancing slows
or the expected life of the mortgage servicing portfolio lengthens. Amortization
of mortgage  servicing rights increased by $4.6 million as a result of increased
refinancings during a period of historically low interest rates, which shortened
the expected  life of the  mortgage  servicing  portfolio  and required a faster
amortization  of  existing  mortgage  servicing  rights.  The 2003  period  also
included  $276  thousand of  amortization  of  insurance  customer  relationship
intangibles from the CSI business combination.

Income Taxes
For the six months ended June 30, 2003,  Trustmark's combined effective tax rate
was  34.8%,  compared  with 35.3% for the first half of 2002.  The  decrease  in
Trustmark's effective tax rate is due to immaterial changes in various permanent
items as a percentage of pretax income.

LIQUIDITY

The liquidity position of Trustmark is monitored on a daily basis by Trustmark's
Treasury  department.   In  addition,  the  Asset/Liability   Committee  reviews
liquidity  on a regular  basis and  approves  any changes in  strategy  that are
necessary as a result of anticipated  balance sheet or cash flow changes.  Also,
on a monthly  basis,  Management  compares  Trustmark's  liquidity  position  to
established corporate policies.  Trustmark was able to improve overall liquidity
capacity  over the last  year,  as  indicated  by the  reduction  in the loan to
deposit  ratio and  reliance  on  wholesale  funding.  The  ability to  maintain
consistent cash flows from operations as well as adequate  capital also enhances
Trustmark's liquidity.

The  primary  source of  liquidity  on the asset side of the  balance  sheet are
maturities and cash flows from both loans and securities, as well as the ability
to sell certain loans and  securities.  With mortgage rates at historical  lows,
increased  prepayments on mortgage loans have also provided an additional source
of liquidity for Trustmark. Liquidity on the liability side of the balance sheet
is generated  primarily through growth in core deposits.  To provide  additional
liquidity,   Trustmark   utilizes   economical   short-term   wholesale  funding
arrangements  for federal funds purchased and securities  sold under  repurchase
agreements  in both  regional and  national  markets.  At June 30,  2003,  these
arrangements gave Trustmark  approximately $1.426 billion in borrowing capacity,
compared  with $1.482  billion as of December 31, 2002.  In addition,  Trustmark
maintains a borrowing  relationship with the FHLB, which provided $125.0 million
in  short-term  advances and $457.6  million in  long-term  advances at June 30,
2003,  compared with $107.7 million in short-term advances and $475.0 million in
long-term  advances at December 31, 2002. These advances are collateralized by a
blanket  lien  on  Trustmark's  single-family,  multi-family,  home  equity  and
commercial mortgage loans. Under the existing borrowing agreement, Trustmark has
$540.8 million  available in unused FHLB advances.  Another  borrowing source is
the  Federal  Reserve  Discount  Window  (Discount  Window).  At June 30,  2003,
Trustmark had approximately  $536 million available in borrowing capacity at the
Discount  Window from pledges of auto loans and  securities,  compared with $541
million  available at December 31, 2002. In June 2002,  Trustmark entered into a
two-year  line of credit  arrangement  enabling  borrowings  up to $50  million,
subject to certain financial  covenants.  As of June 30, 2003, Trustmark had not
drawn upon this line of credit.

On April 16, 2003, Trustmark filed a registration statement on Form S-3 with the
Securities  and  Exchange  Commission  (SEC)  utilizing  a "shelf"  registration
process, which became effective May 2, 2003. Under this shelf process, Trustmark
may offer  from time to time any  combination  of  securities  described  in the
prospectus in one or more  offerings up to a total amount of $200  million.  The
securities  described in the  prospectus  include  common and  preferred  stock,
depositary  shares,  debt securities,  junior  subordinated  debt securities and
trust preferred securities. Net proceeds from the sale of the offered securities
may be used to redeem or repurchase  outstanding  securities,  repay outstanding
debt,  finance  acquisitions  of companies and other assets and provide  working
capital.

On April 9, 2002, the shareholders approved a proposal by the Board of Directors
to amend the Articles of  Incorporation  to  authorize  the issuance of up to 20
million preferred shares with no par value. The Board of Directors believes that
authorizing preferred shares for potential issuance is advisable and in the best
interests of Trustmark. The ability to issue preferred shares in the future will
provide Trustmark with additional  financial and management  flexibility.  As of
June 30, 2003, no such shares have been issued.


CAPITAL RESOURCES

At June 30,  2003,  Trustmark's  shareholders'  equity  was  $664.4  million,  a
decrease of $15.2 million,  or 2.2%,  from its level at December 31, 2002.  This
decline in  shareholders'  equity is due primarily to the change in  accumulated
other  comprehensive  income  resulting  from a decline in the  valuation of AFS
securities.  Net income for the six months  ended June 30, 2003,  totaled  $55.6
million and was offset by  dividends  in the amount of $19.6  million and shares
repurchased at a cost of $37.7 million.

Common Stock Repurchase Program
On July 15, 2003,  the Board of Directors of Trustmark  authorized an additional
plan to  repurchase  up to 5% of common  stock,  or  approximately  3.0  million
shares,  subject to market conditions and management  discretion.  Collectively,
the capital management plans adopted by Trustmark since 1998 have authorized the
repurchase  of 21.5  million  shares of common  stock.  Pursuant to these plans,
Trustmark has repurchased  approximately 17.2 million shares for $363.4 million,
including 1.6 million  shares  during the first half of 2003 for $37.7  million.
The current  remaining  authorization  is approximately  4.3 million shares.  On
October 15, 2002, the Board of Directors of Trustmark authorized the transfer of
$200.0 million from retained  earnings to surplus to replenish funds used in the
common stock repurchase program.

Dividends
Dividends  for the first six  months of 2003 were  $0.33 per  share,  increasing
10.0% when compared with dividends of $0.30 per share for the prior-year period.
Trustmark's  dividend  payout  ratio,  which is dividends  per share  divided by
earnings per share, was 35.11% for the first half of 2003,  compared with 30.61%
for the same period in 2002.

Regulatory Capital
Trustmark  and TNB are  subject  to  minimum  capital  requirements,  which  are
administered by various federal regulatory agencies. These capital requirements,
as defined by federal guidelines,  involve quantitative and qualitative measures
of assets,  liabilities and certain  off-balance sheet  instruments.  Failure to
meet minimum capital  requirements can initiate certain mandatory,  and possibly
additional discretionary,  actions by regulators that, if undertaken, could have
a direct material effect on the financial  statements of both Trustmark and TNB.
Trustmark aims not only to exceed the minimum  capital  standards,  but also the
well capitalized  guidelines for regulatory capital.  Management believes, as of
June 30, 2003,  that  Trustmark  and TNB have met or exceeded all of the minimum
capital  standards for the parent company and its primary banking  subsidiary as
established  by  regulatory  requirements.  At June 30,  2003,  the most  recent
notification  from the Office of the  Comptroller of the Currency  (OCC),  TNB's
primary federal banking  regulator,  categorized TNB as well capitalized.  To be
categorized in this manner,  TNB must maintain minimum total risk-based,  Tier 1
risk-based and Tier 1 leverage ratios (defined in applicable regulations) as set
forth in the table on page 23.  There are no  significant  conditions  or events
that have occurred since the OCC's  notification  that Management  believes have
affected TNB's present classification.

EARNING ASSETS

Earning  assets  serve as the  primary  revenue  streams for  Trustmark  and are
comprised of  securities,  loans,  federal funds sold and  securities  purchased
under resale  agreements.  At June 30, 2003, earning assets were $6.694 billion,
or 90.79% of total  assets,  compared  with $6.453  billion,  or 90.40% of total
assets at December 31, 2002, an increase of $241.4 million, or 3.7%. The primary
component  of this  growth  was a 4.5%  increase  in loans  in a  period  of low
interest rates.

Securities
The  securities  portfolio  consists  primarily  of debt  securities,  which are
utilized to provide Trustmark with a quality investment alternative and a stable
source of interest income,  as well as collateral for pledges on public deposits
and repurchase agreements.  Additionally,  the securities portfolio is used as a
tool to manage risk from movements in interest rates,  to support  profitability
and to offset risks incurred by business units.  When evaluating the performance
of the securities  portfolio,  Management considers not only interest income but
also the  flexibility  and liquidity  provided by changes in fair value. At June
30, 2003, Trustmark's  securities portfolio totaled $1.849 billion,  compared to
$1.812 billion at December 31, 2002, an increase of $37.2 million, or 2.1%.

The  securities  portfolio  is a  powerful  risk  management  tool that  enables
Management to control both the invested  balance and the duration of securities.
In  addition  to  first  quarter  2003  sales of $99.1  million  of  securities,
significant price changes in certain portfolio  securities  enabled Trustmark to
sell  securities  with a total  fair value of $189.0  million  during the second
quarter  of 2003.  Approximately  $137.8  million  of  proceeds  from the second
quarter  securities  sales were  reinvested  in  short-term  treasury and agency
securities. Trustmark has continued its strategy of reducing price volatility in
the investment portfolio as indicated by duration. The estimated duration of the
portfolio  was  measured to be 2.83 years at December  31,  2001,  1.94 years at
December 31, 2002,  and 1.54 years at June 30, 2003. By reducing the duration of
the portfolio,  Trustmark has reduced exposure to volatile  interest rates while
increasing  liquidity and flexibility.  Management intends to keep the portfolio
near  historically  low duration  levels  while the interest  rate cycle is in a
stage of lower yields.

AFS securities are carried at their estimated fair value with  unrealized  gains
or losses recognized, net of taxes, in accumulated other comprehensive income, a
separate  component of  shareholders'  equity.  At June 30, 2003, AFS securities
totaled $1.537 billion,  which  represented  83.1% of the securities  portfolio,
compared to $1.263  billion,  or 69.7%,  at December 31, 2002. At June 30, 2003,
AFS securities consisted of U.S. Treasury and Agency securities,  obligations of
states  and  political  subdivisions,  mortgage  related  securities  and  other
securities,  primarily  Federal  Reserve Bank and FHLB stock.  At June 30, 2003,
unrealized  losses on AFS  securities  of $6.8  million,  net of $2.6 million of
deferred income tax benefits,  were included in accumulated other  comprehensive
income,  compared  with gains of $22.8  million,  net of $8.7  million in income
taxes, at December 31, 2002.

Held to maturity  (HTM)  securities  are carried at amortized cost and represent
those  securities  that  Trustmark  both  intends and has the ability to hold to
maturity.   At  June  30,  2003,  HTM  securities  totaled  $312.0  million  and
represented  16.9% of the total  portfolio,  compared  with $549.2  million,  or
30.3%,  at the end of 2002.  This  decrease  is from  calls  and  maturities  of
securities,  the  proceeds  of which  were  used to  purchase  shorter  duration
mortgage related securities.

Management  continues to focus on asset quality as one of the strategic goals of
the  securities  portfolio,  which is evidenced by the investment of over 85% of
the portfolio in U.S. Treasury and U.S. Government agencies obligations.

Loans and Allowance for Loan Losses
Loans,  including  loans held for sale,  represented  72.1% of earning assets at
June 30, 2003,  compared with 71.6% at year-end  2002.  At June 30, 2003,  loans
totaled  $4.826  billion,  a 4.5% increase  from its level of $4.617  billion at
December 31, 2002.  Real estate lending  continued to be positively  impacted by
record low interest rates while other loan areas have been  negatively  affected
by a weakened economy.

Trustmark  makes loans in the normal  course of  business to certain  directors,
including  their  immediate  families and  companies in which they are principal
owners. Such loans are made on substantially the same terms,  including interest
rates  and  collateral,   as  those   prevailing  at  the  time  for  comparable
transactions with unrelated persons and do not involve more than the normal risk
of collectibility at the time of the transaction.


Trustmark's  lending policies have resulted in consistently sound asset quality.
One measure of asset quality in the financial  services industry is the level of
nonperforming  assets. The details of Trustmark's  nonperforming  assets at June
30,  2003  and  December  31,  2002,  are  shown  in  the  accompanying   table.

- --------------------------------------------------------------------------------

Total  nonperforming  assets decreased $1.9 million,  or 5.0%,  during the first
half of 2003. Most of this decline was attributable to loans returned to accrual
status as the result of an intensified review of nonaccrual loans less than $100
thousand. The allowance coverage of nonperforming loans remains strong at 258.7%
at June 30, 2003, compared with 236.3% at December 31, 2002.

At June 30, 2003, the allowance for loan losses was $74.8  million,  maintaining
the year-end  2002 level.  The allowance  for loan losses  represented  1.55% of
total loans  outstanding  at June 30,  2003,  compared to 1.62% at December  31,
2002.  As of June 30, 2003,  Management  believes  that the  allowance  for loan
losses provides adequate protection in regards to charge-off  experience and the
current level of nonperforming assets.

Net charge-offs were $5.6 million, or 0.24% of average loans, for the six months
ended June 30, 2003,  compared with $6.9 million, or 0.31% of average loans, for
the prior year period.  This improvement is primarily from gross  charge-offs of
commercial  purpose loans, which decreased $1.4 million when comparing the first
six  months  of 2003 and  2002.  Charge-offs  for the  first  half of 2002  were
affected by five larger commercial loan losses totaling $2.6 million.

Other Earning Assets
Federal funds sold and securities purchased under reverse repurchase  agreements
were $19.6  million at June 30, 2003,  a decrease of $4.4 million when  compared
with year-end 2002. Trustmark utilizes these products as a short-term investment
alternative whenever it has excess liquidity.

DEPOSITS AND OTHER INTEREST-BEARING LIABILITIES

Trustmark's  deposit base is its primary  source of funding and consists of core
deposits  from the  communities  served  by  Trustmark.  Deposits  include  both
interest-bearing and noninterest-bearing demand accounts, savings, money market,
certificates of deposits and individual retirement accounts. Total deposits were
$4.967  billion at June 30, 2003,  compared with $4.686  billion at December 31,
2002, an increase of $280.5 million,  or 6.0%.  This growth  primarily came from
seasonal increases in public interest-bearing demand deposits.  During the first
half of 2003,  interest-bearing  deposits increased $224.9 million, or 6.5%, and
noninterest-bearing  deposits  increased  $55.6  million,  or 4.4%.  Trustmark's
deposit mix remains  favorable with  noninterest-bearing  deposits  representing
26.3% of total deposits at June 30, 2003,  compared with 26.7% at year-end 2002.
Trustmark  will  continue to seek  deposits by expanding  its presence in higher
growth markets and evaluating additional wholesale deposit funding sources.

Short-term borrowings consist of federal funds purchased,  securities sold under
repurchase agreements, FHLB borrowings and the treasury tax and loan note option
account.  Short-term  borrowings  totaled  $1.216  billion at June 30,  2003,  a
decrease  of $15.3  million,  compared  with $1.231  billion at  year-end  2002.
Trustmark  has used the  liquidity  created by  maturing  securities  as well as
increased core deposits to reduce reliance on wholesale funding.

Long-term  FHLB advances  totaled $457.6 million at June 30, 2003, a decrease of
$17.4 million from December 31, 2002.  These totals  include  $250.0  million in
advances with variable rates adjusting  quarterly,  while the remaining advances
are fixed rate,  primarily maturing from 2004 to 2006. During the second quarter
of  2003,  Trustmark  implemented  the  use  of  swap  agreements,   effectively
converting  $100.0  million of the fixed rate  advances to variable  rates.  For
further discussion,  see Market/Interest  Rate Risk Management beginning on page
27.


CONTINGENCIES

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.  In recent years, the
legal  environment in Mississippi  has been  considered by many to be adverse to
business  interests  in regards to the overall  treatment  of tort and  contract
litigation  as well as the  award of  punitive  damages.  However,  tort  reform
legislation that became effective  January 1, 2003, may reduce the likelihood of
unexpected sizable awards. At the present time,  Management  believes,  based on
the  advice  of legal  counsel  and  Management's  evaluation,  that  the  final
resolution  of pending  legal  proceedings  will not have a  material  impact on
Trustmark's consolidated financial position or results of operations.

At December 31, 2002,  Trustmark's  pension plan was  underfunded,  requiring an
accrual for minimum pension liability of $5.7 million.  During the first quarter
of 2003, the Board of Directors  approved a  tax-deductible  contribution to the
pension plan in the amount of $7.0 million.  A minimum pension liability of $5.7
million will be reevaluated at the plan's measurement date, October 31, 2003.

ASSET/LIABILITY MANAGEMENT

Overview
Market risk is the risk of loss arising from  adverse  changes in market  prices
and rates.  Trustmark has risk management policies to monitor and limit exposure
to market risk.  Trustmark's market risk is comprised primarily of interest rate
risk created by core banking  activities.  Interest rate risk is the risk to net
interest  income  represented by the impact of higher or lower  interest  rates.
Management continually develops and applies cost-effective  strategies to manage
these  risks.  The  Asset/Liability  Committee  sets  the  day-to-day  operating
guidelines,  approves  strategies  affecting net interest income and coordinates
activities  within policy limits  established  by the Board of Directors.  A key
objective of the asset/liability  management program is to quantify, monitor and
manage interest rate risk and to assist  Management in maintaining  stability in
the net interest margin under varying interest rate environments.

Market/Interest Rate Risk Management
The  primary  purpose  in  managing  interest  rate  risk is to  invest  capital
effectively and preserve the value created by the core banking business. This is
accomplished  through the development and  implementation  of lending,  funding,
pricing  and  hedging  strategies  designed  to  maximize  net  interest  income
performance  under  varying  interest  rate  environments  subject  to  specific
liquidity and interest rate risk guidelines.

Management  has  continued to maintain a balance sheet  position that  mitigates
adverse effects of rising interest rates. Modeling static balances from June 30,
2003, it is estimated that net interest income may increase, possibly as much as
9.71%, in a one-year,  shocked, up 200 basis point rate shift scenario, compared
to a base case,  flat rate  scenario for the same time period.  This is a slight
improvement in exposure to rising rates when compared to December 31, 2002. In a
shocked,  down 200 basis point rate shift scenario,  net income may decline from
the base case as much as 10.15% in a one-year horizon. Management cannot provide
any  assurance  about the  actual  effect of changes  in  interest  rates on net
interest income.  The estimates  provided do not include the effects of possible
strategic  changes in the balances of various assets and liabilities  throughout
the remainder of 2003.  Management will continue to monitor the balance sheet as
balances change and maintain a proactive stance to manage interest rate risk.

The primary tool  utilized by the  Asset/Liability  Committee  is a  third-party
modeling system which is widely accepted in the financial institutions industry.
This system  provides  information  used to evaluate  exposure to interest  rate
risk,  project  earnings and manage balance sheet growth.  This modeling  system
utilizes  the  following  scenarios  in order  to give  Management  a method  of
evaluating  Trustmark's interest rate, basis and prepayment risk under different
conditions:

   o     Rate shocked scenarios of up-and-down 100, 200 and 300 basis points.
   o     Yield curve twist of +/- 2 standard  deviations of the change in spread
         of the three-month Treasury bill and the 10-year Treasury note yields.
   o     Basis  risk  scenarios  where  federal  funds/LIBOR  spread  widens and
         tightens  to the high and low  spread  determined  by using 2  standard
         deviations.
   o     Prepayment  risk  scenarios  where  projected   prepayment   speeds  in
         up-and-down  200 basis  point rate  scenarios  are  compared to current
         projected prepayment speeds.


A static gap analysis is a tool used mainly for interest rate risk  measurement,
in which the balance sheet amounts as of a certain date are stratified  based on
repricing  frequency.  The assets and  liabilities  repricing  in a certain time
frame are then compared to determine the gap between assets and  liabilities for
that  period.  If assets are greater than  liabilities  for the  specified  time
period,  then  the  balance  sheet  is  said to be in an  asset  gap,  or  asset
sensitive,  position. This analysis is helpful in that it highlights significant
short-term repricing volume mismatches.  Management's assumptions related to the
prepayment  of certain  loans and  securities,  as well as the maturity for rate
sensitive  assets and  liabilities,  are  utilized  for  sensitivity  static gap
analysis.  Three-month  gap analysis  projected  at June 30, 2003,  reflected an
asset gap of $177  million,  an  improvement  from the liability gap position of
$257 million at June 30, 2002. One-year gap analysis projected at June 30, 2003,
reflected an asset gap of $548 million,  an improvement  from a liability gap of
$73  million  at June 30,  2002.  This new static gap  analysis  indicates  that
Trustmark is better  positioned for the  possibility  of a rising  interest rate
environment.

As part of Trustmark's  risk management  strategy in the mortgage  banking area,
various  derivative  instruments  such as  interest  rate lock  commitments  and
forward  sales  contracts  are utilized.  Forward  contracts  are  agreements to
purchase  or sell  securities  or other  money  market  instruments  at a future
specified  date at a specified  price or yield.  Trustmark's  obligations  under
forward contracts  consist of commitments to deliver mortgage loans,  originated
and/or purchased, in the secondary market at a future date. Effective January 1,
2003,  Trustmark has  redesignated  these  derivative  instruments as fair value
hedges as permitted by Statement of Financial  Accounting  Standards  (SFAS) No.
133,  "Accounting  for  Derivatives  Instruments  and  Hedging  Activities,"  as
amended.  Under SFAS No. 133, changes in the values of derivatives designated as
fair value hedges are  recognized  in  earnings.  In this case  Trustmark  would
recognize  changes  in the  values of the  designated  derivatives  in  earnings
simultaneously with changes in the values of the designated hedged loans. To the
extent changes in the values of the derivatives are 100% effective in offsetting
changes  in the  values of  hedged  loans,  the fair  value  adjustments  on the
derivatives and hedged loans would offset one another. In contrast,  Trustmark's
previous  designation  of these  derivatives  as cash flow  hedges  resulted  in
changes in value being recognized in accumulated other comprehensive income, net
of taxes,  a component of  Shareholders'  Equity,  and in  earnings.  Management
anticipates  that this change will help  mitigate  the  potential  for  earnings
volatility related to the valuation of these hedging instruments in the future.

Trustmark continued a risk controlling strategy utilizing caps and floors, which
may be further  implemented  over time.  As of June 30, 2003,  Trustmark was not
utilizing interest rate floors but had interest rate cap contracts with notional
amounts  totaling  $300 million,  which mature in 2006.  The intent of utilizing
these financial instruments is to reduce the risk associated with the effects of
significant  movements  in  interest  rates.  Caps  and  floors,  which  are not
designated as hedging instruments for accounting purposes, are options linked to
a notional principal amount and an underlying indexed interest rate. Exposure to
loss on these options will increase or decrease as interest rates fluctuate.

Another  tool used for interest  rate risk  management  is interest  rate swaps.
Interest rate swaps are  derivative  contracts  under which two parties agree to
make interest  payments on a notional  principal  amount. In a generic swap, one
party pays a fixed interest rate and receives a floating interest rate while the
other party  receives a fixed  interest rate and pays a floating  interest rate.
During April 2003,  Trustmark initiated four separate interest rate swaps with a
total notional  principal  amount of $100 million.  During July 2003,  Trustmark
added  another  interest  rate  swap  with a  notional  principal  amount of $25
million.  Trustmark  initiated  these swaps to  mitigate  the effects of further
changes in the fair value of  specific  noncallable,  nonprepayable,  fixed rate
advances  from the FHLB by  agreeing  to pay a  floating  interest  rate tied to
LIBOR.  The  swap  contracts  are tied to the  maturity  of five  separate  FHLB
advances maturing between 2005 and 2006.

RECENT PRONOUNCEMENTS

In May 2003,  the Financial  Accounting  Standards  Board (FASB) issued SFAS No.
150, "Accounting for Certain Financial  Instruments with Characteristics of both
Liabilities and Equity." This statement  establishes standards for how an issuer
classifies and measures certain financial  instruments with  characteristics  of
both  liabilities  and equity.  The  statement  applies to three  categories  of
freestanding   financial   instruments:   1)  certain   mandatorily   redeemable
instruments,  2) instruments with repurchase obligations and 3) instruments with
obligations to issue a variable  number of shares.  The statement  requires that
previously  issued  instruments that fall within the scope of the statement must
be reclassified as liabilities,  and subsequent  changes in the  measurements of
the  instruments  treated  as  liabilities  must  flow  through  to  the  income
statement.  For  public  companies,  this  statement  became  effective  for all
freestanding  financial instruments entered into or modified after May 31, 2003.
Otherwise it becomes  effective at the  beginning  of the first  interim  period
beginning after June 15, 2003. Currently,  Trustmark does not have any financial
instruments within the scope of this statement.


In April 2003,  the FASB  issued SFAS No. 149,  "Amendment  of Statement  133 on
Derivative  Instruments  and  Hedging  Activities."  This  statement  amends and
clarifies  financial  accounting  and  reporting  for  derivative   instruments,
including   certain   derivative   instruments   embedded  in  other   contracts
(collectively  referred to as derivatives) and for hedging activities under SFAS
No. 133,  "Accounting for Derivative  Instruments and Hedging  Activities." This
statement is effective  for  contracts  entered into or modified  after June 30,
2003, and for hedging relationships  designated after June 30, 2003. The effects
of this  statement did not have a material  impact on  Trustmark's  consolidated
financial position or results of operations upon adoption on June 30, 2003.

The information required by this item is included in "Market/Interest  Rate Risk
Management"  (pages 27-28) of "Item 2.  Management's  Discussion and Analysis of
Financial Condition and Results of Operations."

ITEM 4.  CONTROLS AND PROCEDURES

For the period ending June 30, 2003,  Trustmark  evaluated the  effectiveness of
the design and operation of its disclosure  controls and procedures  pursuant to
Rules 13a-14 and 15d-14 under the  Securities  Exchange Act of 1934,  as amended
(Exchange  Act),  under  the  supervision  and  with  the  participation  of its
management,  including  the  Chief  Executive  Officer  and the  Treasurer  (the
Principal  Financial Officer).  Based upon this evaluation,  the Chief Executive
Officer and the  Treasurer  concluded  that,  as of June 30,  2003,  Trustmark's
disclosure  controls and  procedures  were  adequate to ensure that  information
required to be disclosed  by  Trustmark in the reports  filed or submitted by it
under the Exchange Act is recorded,  processed,  summarized and reported  within
the time periods specified in the rules and forms of the Securities and Exchange
Commission. Subsequent to this review, there have been no significant changes in
Trustmark's  internal  controls  or in other  factors  that could  significantly
affect these controls.
