                      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 and Article 10 of Regulation S-X. 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.  Management is required to make estimates and assumptions
that affect the amounts  reported in the consolidated  financial  statements and
accompanying  notes.  Actual results could differ from those  estimates.  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.  Operating  results for the three and nine month
periods ended September 30, 2004, are not necessarily  indicative of the results
that may be expected for the year ended  December 31, 2004.  The notes  included
herein  should  be  read in  conjunction  with  the  notes  to the  consolidated
financial statements included in Trustmark Corporation's (Trustmark) 2003 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 November 2, 2004,  Trustmark  announced  the signing of an agreement in which
Fisher-Brown,  Inc. would become a wholly owned subsidiary of Trustmark National
Bank.  Founded in 1911,  Fisher-Brown  is the leading  general  lines  insurance
agency in  Northwest  Florida,  providing a broad  spectrum  of risk  management
products  to  businesses  and  individuals  in  Northwest  Florida.  With annual
revenues of $16 million, Fisher-Brown is headquartered in Pensacola, Florida and
has  offices in Milton,  Mary  Esther,  Destin and  Panama  City,  Florida.  The
transaction,  which is subject to due  diligence,  is  expected  to close in the
fourth quarter of 2004.

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

On August 29,  2003,  Trustmark  acquired  seven  Florida  branches  of The Banc
Corporation of Birmingham,  Alabama, in a business combination  accounted for by
the purchase method of accounting.  These  branches,  known as the Emerald Coast
Division,  serve the markets from Destin to Panama City. In connection  with the
transaction,  Trustmark  paid a $46.8  million  deposit  premium in exchange for
$232.8 million in assets and $209.2  million in deposits and other  liabilities.
Assets  consisted of $224.3 million in selected loans,  $6.8 million in premises
and  equipment and $1.7 million in other  assets.  These assets and  liabilities
have  been  recorded  at  fair  value  based  on  market   conditions  and  risk
characteristics  at the acquisition  date. Loans were recorded at a $1.9 million
discount,  consisting  of a discount  for general  credit  risk of $3.5  million
offset by a market premium of $1.6 million. This net discount will be recognized
as  interest  income over the  estimated  life of the loans.  Excess  costs over
tangible net assets  acquired  totaled $49.5 million,  of which $1.7 million and
$47.8 million have been allocated to  identifiable  intangibles  (core deposits)
and goodwill, respectively. Trustmark's financial statements include the results
of operations for this acquisition from the merger date. The pro forma impact of
this acquisition on Trustmark's results of operations is insignificant.

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

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 are retained,  Trustmark  allocated the cost of the
loan and the  servicing  right based on their  relative  fair  values.  Mortgage
servicing  rights are  amortized  over the  estimated  period of the related new
servicing  income.  At September  30, 2004,  Trustmark  serviced $3.4 billion in
mortgage loans for others.

Impairment  for mortgage  servicing  rights occurs when the estimated fair value
falls below the underlying  carrying value.  Fair value is determined  utilizing
specific risk  characteristics  of the mortgage loan, current interest rates and
current  prepayment  speeds.  During  the  second  quarter  of  2004,  Trustmark
reclassified $6.6 million of mortgage  servicing right impairment from temporary
to other-than-temporary which reduced the valuation allowance for impairment and
the gross mortgage  servicing  rights balance with no effect to the net mortgage
servicing rights asset. Impairment is considered to be other-than-temporary when
Trustmark  determines  that the  carrying  value is  expected to exceed the fair
value for an extended period of time.

At September 30, 2004 and December 31, 2003, deposits consisted of the following

NOTE 6 - STOCK-BASED COMPENSATION

Effective  January  1,  2003,  Trustmark  adopted  the  fair  value  recognition
provisions  of SFAS No.  123,  "Accounting  for  Stock-Based  Compensation,"  as
amended by SFAS No. 148,  "Accounting for Stock-Based  Compensation - Transition
and Disclosure"  prospectively for all awards granted, modified or settled after
January 1, 2003. Under the provisions of this statement, compensation expense is
recognized  by the straight line method for grants issued after January 1, 2003,
utilizing  the fair  value of the  grants  over the  vesting  period.  Trustmark
estimates  the  fair  value  of each  option  granted  using  the  Black-Scholes
option-pricing  model.  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.  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 except per share data):

NOTE 7 - CONTINGENCIES

Standby Letters of Credit
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 September 30, 2004, the maximum potential amount of future payments Trustmark
could be required to make under its standby letters of credit was $94.7 million,
which  also   represented   the  maximum  credit  risk   associated  with  these
commitments.  This amount consisted  primarily of commitments with maturities of
less than  three  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 September 30, 2004,  the fair value of collateral
held was $22.9 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;  however, Management is unable to estimate a range of potential loss
on these matters because of the nature of the legal  environment in states where
Trustmark conducts business.

NOTE 8 - ASSOCIATE PENSION PLAN

Trustmark maintains a noncontributory  defined benefit pension plan which covers
substantially  all  associates  with  more  than one year of  service.  The plan
provides  pension  benefits  that are based on credited  service,  final average
compensation and the benefit formula as defined in the plan.  Trustmark's policy
is to fund amounts allowable for federal income tax purposes,  making sufficient
contributions to satisfy the minimum funding  requirement for each plan year and
making additional contributions, as needed, based on the plan's funded status as
of the October 31 measurement date.

The following table presents  information  regarding net periodic  pension costs
for the nine months ended September 30, 2004 and 2003 ($ in thousands):

The table above shows the recognized net loss due to early  retirement of $2.378
million,  resulting  from a voluntary  early  retirement  program  announced  by
Trustmark in February  2003.  This program was offered to associates  age 58 and
above with ten years or more of service and was accepted by 116  associates,  or
4.75% of Trustmark's workforce.

The acceptable range of contributions to the plan is determined each year by the
plan's actuary as of the measurement  date,  which is October 31st.  Trustmark's
minimum required contribution for the current year is zero; however, Trustmark's
Management and Board of Directors approved a contribution of $11 million,  which
was made in October 2004.


NOTE 9 - 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 dilutive 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 10 - STATEMENTS OF CASH FLOWS

Trustmark  paid income taxes of $37.4 million and $45.3 million  during the nine
months ended September 30, 2004 and 2003, respectively. Interest paid on deposit
liabilities and other borrowings  totaled $62.4 million in the first nine months
of 2004 and $70.8 million in the first nine months of 2003.  For the nine months
ended  September 30, 2004 and 2003,  noncash  transfers from loans to foreclosed
properties  were $3.8 million and $4.4 million,  respectively.  Assets  acquired
during  the first  quarter of 2004 as a result of the  Allied  Houston  business
combination  totaled $148.1 million,  while  liabilities  assumed totaled $161.7
million.  During the first nine months of 2004, $175.0 million of long-term FHLB
advances were transferred to short-term  borrowings  compared with net transfers
of $42.3 million in the first nine months of 2003.

NOTE 11 - RECENT PRONOUNCEMENTS

In March 2004, the Emerging Issues Task Force (EITF) of the Financial Accounting
Standards Board (FASB) issued EITF 03-1 "The Meaning of Other-than-Temporary and
its  Application  to Certain  Investments".  EITF 03-1 requires an evaluation of
investment securities to determine if impairment is  "other-than-temporary".  If
impairment is deemed to be  other-than-temporary  based on certain criteria,  an
impairment loss equal to the difference  between the  investment's  cost and its
fair value is recognized.  EITF 03-1 also requires additional disclosure related
to unrealized losses. The disclosure requirements of EITF 03-1 are effective for
annual reporting periods ending after June 15, 2004. The impairment requirements
of EITF 03-1 are currently delayed pending clarification.

On March 9, 2004,  the  Securities  and Exchange  Commission  (SEC) issued Staff
Accounting  Bulletin No. 105,  "Application  of  Accounting  Principles  to Loan
Commitments".  This bulletin summarizes the views of the SEC staff regarding the
application  of generally  accepted  accounting  principles to loan  commitments
accounted for as derivative  instruments.  The adoption of this bulletin did not
impact Trustmark's consolidated financial statements.

In December 2003, the Accounting  Standards  Executive Committee of the American
Institute of Certified Public  Accountants  (AICPA) issued Statement of Position
(SOP) No. 03-3,  "Accounting for Certain Loans or Debt Securities  Acquired in a
Transfer." SOP 03-3 addresses accounting for differences between the contractual
cash flows of certain loans and debt  securities  and the cash flows expected to
be collected when loans or debt  securities are acquired in a transfer and those
cash flow differences are attributable,  at least in part, to credit quality. As
such, SOP 03-3 applies to loans and debt securities  acquired  individually,  in
pools or as part of a  business  combination  and does not  apply to  originated
loans.  The  application  of SOP 03-3  limits  the  interest  income,  including
accretion of purchase price discounts,  that may be recognized for certain loans
and debt  securities.  Additionally,  SOP 03-3  does not  allow  the  excess  of
contractual cash flows over cash flows expected to be collected to be recognized
as an  adjustment  of yield,  loss accrual or valuation  allowance,  such as the
allowance for possible loan losses. SOP 03-3 requires that increases in expected
cash flows  subsequent to the initial  investment  be  recognized  prospectively
through  adjustment of the yield on the loan or debt security over its remaining
life.  Decreases in expected cash flows should be recognized as  impairment.  In
the case of loans acquired in a business  combination where the loans show signs
of credit  deterioration,  SOP 03-3 represents a significant change from current
purchase accounting practice whereby the acquiree's allowance for loan losses is
typically  added  to the  acquirer's  allowance  for  loan  losses.  SOP 03-3 is
effective for loans and debt securities  acquired by Trustmark beginning January
1, 2005.  The  adoption of this new  standard is not expected to have a material
impact on Trustmark's financial statements.

NOTE 12 - SEGMENT INFORMATION

During the first quarter of 2004,  Trustmark realigned its management  reporting
structure  to  include  four  segments  that  include  general  banking,  wealth
management,  insurance and administration.  The general banking segment realigns
Trustmark's  former  consumer  and  commercial  segment into a single group that
delivers a full range of banking  services to  consumers,  corporate,  small and
middle  market  businesses  through  its  extensive  branch  network.  Trustmark
realigned  its former  investment  segment  into the wealth  management  segment
incorporating trust, brokerage, investment advisory, and private banking service
under one umbrella.  The insurance  segment,  formerly  included in the consumer
segment,  represents  Trustmark's  retail insurance agency that offers a diverse
mix of insurance products and services.  The administrative segment incorporates
Trustmark's  treasury function with various  non-allocated  corporate  operation
units and includes intangible assets and related  amortization  (except mortgage
servicing  rights and  related  amortization,  which is  included in the general
banking segment).

The accounting  policies of each reportable segment are the same as those of the
Corporation except for its internal  allocations.  Trustmark uses a match-funded
transfer pricing process to assess operating segment  performance.  Non-interest
expenses for back-office  operations  support are allocated to segments based on
estimated uses of those services.  Income tax expense for segments is calculated
at the marginal statutory rate.

The following table discloses  financial  information by reportable  segment for
the  periods  ended  September  30,  2004 and 2003.  The prior  period  has been
restated to conform with the current period 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.

Forward-Looking Statements

Certain  statements  contained in  Management's  Discussion and Analysis are not
statements of historical fact and constitute  forward-looking  statements within
the  meaning of the  Private  Securities  Litigation  Reform Act of 1995.  These
forward-looking  statements relate to anticipated future operating and financial
performance measures,  including net interest margin,  credit quality,  business
initiatives,  growth  opportunities and growth rates, among other things.  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
     historically low interest rate environment would have an impact on the fair
     value  of  the  mortgage   servicing   portfolio.   In  addition,   premium
     amortization  on  mortgage  related  securities   included  in  Trustmark's
     securities  portfolio  would  also  be  accelerated  as  prepayment  of the
     mortgage loans securing these  securities  occur.  The combination of these
     events could materially affect Trustmark's results of operations.
o    The costs and effects of litigation  and of unexpected or adverse  outcomes
     in such litigation can materially affect Trustmark's results of operations.
o    Competition  in loan  and  deposit  pricing,  as well as the  entry  of new
     competitors  into our markets  through de novo expansion and  acquisitions,
     among other means,  could have an effect on  Trustmark's  operations in our
     existing  markets.
o    Trustmark  is  subject  to  regulation  by  federal  banking  agencies  and
     authorities and the Securities and Exchange Commission. Changes in existing
     regulations  or the adoption of new  regulations  could make it more costly
     for Trustmark to do business or could force changes in the manner Trustmark
     does  business,  which  could  have  an  impact  on  Trustmark's  financial
     condition or results of operations.

Although   Management   believes  that  the   expectations   reflected  in  such
forward-looking  statements are  reasonable,  it can give no assurance that such
expectations will prove to be correct.  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.

Overview

Trustmark is an integrated provider of banking,  wealth management and insurance
solutions with over 145 branches and 185 ATMs in Mississippi, Florida, Tennessee
and Texas. Trustmark National Bank (TNB),  Trustmark's  wholly-owned subsidiary,
accounts  for  substantially  all of the assets and  revenues of  Trustmark.  In
addition to banking  activities,  TNB provides investment and insurance products
and services to its customers through three wholly-owned subsidiaries, Trustmark
Securities, 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),  which
serves the Fayette County, Tennessee market.



Basic  earnings  per  share  were  $0.49 for the third  quarter  of 2004,  which
resulted from net income of $28.1 million. Included in the results for the third
quarter of 2004 is a non-cash  after-tax  charge of $1.9 million,  or $0.033 per
share, for impairment of the Company's home mortgage servicing portfolio related
to declines in long-term interest rates during the quarter. In the third quarter
of 2003,  basic  earnings  per share  were  $0.55 and  included  a  reversal  of
previously recorded mortgage servicing  impairment charges,  which increased the
quarter's  after-tax net income by $3.1 million, or $0.052 per share. Net income
for the nine months ended  September 30, 2004,  totaled $87.9 million,  compared
with $88.1 million for the nine months ended September 30, 2003.  Basic earnings
per share were $1.51 for the first nine months of 2004, an increase of 1.3% when
compared with $1.49 for the same period in 2003.  Diluted earnings per share for
the first nine months of 2004 were $1.51,  an  increase  of 2.0%  compared  with
$1.48 for the first nine months of 2003.

Management  utilizes certain financial ratios to gauge Trustmark's  performance.
Trustmark  achieved a return on average  assets of 1.35% and a return on average
equity of 15.26% for the three months ended  September 30, 2004.  These compared
with  ratios of 1.71% for  return on  average  assets  and  19.03% for return on
average  equity for the three months  ended  September  30,  2003.  For the nine
months ended September 30, 2004,  Trustmark  achieved a return on average assets
of 1.44% and a return on average equity of 16.34%.  These compare to a return on
average  assets of 1.61% and a return on  average  equity of 17.58% for the same
period in 2003.

Critical Accounting Policies and Estimates

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.  Critical  accounting  policies  and
estimates  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 are applied to these
policies  and  estimates.  A summary of  significant  accounting  policies and a
description of accounting  policies that are considered critical may be found in
Trustmark's  2003 Annual  Report on Form 10-K,  filed on March 10, 2004,  in the
Notes to the Consolidated  Financial Statements.  Because of recent developments
in mortgage servicing rights, additional information is shown below.

Mortgage Servicing Rights
Impairment  for mortgage  servicing  rights occurs when the estimated fair value
falls below the underlying  carrying value.  Fair value is determined  utilizing
specific risk  characteristics  of the mortgage loan, current interest rates and
current  prepayment  speeds.  During  the  second  quarter  of  2004,  Trustmark
reclassified $6.6 million of mortgage  servicing right impairment from temporary
to other-than-temporary which reduced the valuation allowance for impairment and
the gross mortgage  servicing  rights balance with no effect to the net mortgage
servicing rights asset. Impairment is considered to be other-than-temporary when
Trustmark  determines  that the  carrying  value is  expected to exceed the fair
value for an extended period of time.

Business Combinations

On November 2, 2004,  Trustmark  announced  the signing of an agreement in which
Fisher-Brown,  Inc. would become a wholly owned subsidiary of Trustmark National
Bank.  Founded in 1911,  Fisher-Brown  is the leading  general  lines  insurance
agency in  Northwest  Florida,  providing a broad  spectrum  of risk  management
products  to  businesses  and  individuals  in  Northwest  Florida.  With annual
revenues of $16 million, Fisher-Brown is headquartered in Pensacola, Florida and
has  offices in Milton,  Mary  Esther,  Destin and  Panama  City,  Florida.  The
transaction,  which is subject to due  diligence,  is  expected  to close in the
fourth quarter of 2004.

During  March 2004,  Trustmark  completed  its entry into the  dynamic  Houston,
Texas,  market with the purchase of five branches of Allied Houston Bank.  These
offices,  with loans of $145.9  million and  deposits and other  liabilities  of
$161.7 million, are located in one of Houston's most attractive areas. In August
2003,  Trustmark  completed its expansion into Florida's  vibrant  Emerald Coast
market with the purchase of seven branches of The Banc Corporation.  The Emerald
Coast branches,  with $224.3 million in loans and $209.2 million in deposits and
other  liabilities,  are  located  in  thriving  areas and well  positioned  for
additional growth.  Strategic acquisitions,  which enhance internal growth, will
continue to be an important component of Trustmark's strategic plan. Trustmark's
financial  statements  include the results of operations  for the above purchase
business  combinations from the respective merger dates. The pro forma impact of
these  acquisitions on Trustmark's  results of operations is immaterial.  Please
see the notes to the  consolidated  financial  statements  for  further  details
concerning these acquisitions.


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 Table
on pages 18 and 19 shows 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.

Interest  income-FTE for the third quarter of 2004  increased  $7.8 million,  or
8.9%, when compared to the third quarter of 2003 and $3.1 million, or 3.4%, when
compared  to the  second  quarter  of 2004.  Interest  and  fees on  loans  were
positively  impacted by increases in  short-term  rates based on changes made by
the Federal  Reserve Bank during the third quarter while interest  earned on the
securities  portfolio  benefited  from the slow-down in mortgage  refinancing in
response to higher  long-term  interest rates during the second quarter of 2004.
In reaction,  prepayments of mortgage-backed  securities have slowed and reduced
the  acceleration  of  premium   amortization  on  these  investments  that  had
negatively  affected  interest  income  during  the second  quarter of 2004.  In
addition,  interest  income-FTE has been  positively  impacted by an increase in
average  earning assets of $674.8  million,  or 9.8%,  when the third quarter of
2004 is compared with the third  quarter of 2003.  Without the Emerald Coast and
Allied Houston branch purchases, the increase in average interest-earning assets
for the third quarter of 2004 is $249.4 million, or 3.6%. When compared with the
second  quarter of 2004,  average-earning  assets for the third  quarter of 2004
increased  $47.9 million,  or 0.6%. In this  comparison,  loan growth  increased
$97.8 million,  or 1.8%,  while  securities  decreased  $56.3 million,  or 2.6%.
During the third quarter,  Trustmark utilized the liquidity provided by maturing
investments  to reduce its reliance on wholesale  funding which helped  mitigate
the exposure to the increase in short-term  rates. As a result of these actions,
the yield on earning  assets  for the third  quarter of 2004 was lower than that
experienced during the same period of 2003 (5.01% versus 5.04%),  however,  this
yield  increased  by 8 basis  points  (from  4.93%) when  compared to the second
quarter of 2004.

Increases in short-term  rates also had an impact on interest expense during the
third quarter of 2004.  Interest expense  increased $1.6 million,  or 7.6%, when
compared to the third quarter of 2003 and $2.8 million,  or 13.7%, when compared
to the  second  quarter  of 2004.  A  greater  reliance  on  wholesale  funding,
including federal funds purchased,  securities sold under repurchase  agreements
and Federal Home Loan Bank (FHLB) advances, during the third quarter of 2004 was
necessary in order to  compensate  for reduced  funding from  deposits.  This is
illustrated by the increase in wholesale funding products of $129.4 million when
the third  quarter of 2004 is compared  with the second  quarter of 2004,  which
offset a decline of $101.9 million in interest-bearing  deposits during the same
time  period.  While  the cost of  interest-bearing  liabilities  for the  third
quarter of 2004 was lower than that  experienced  during the same period of 2003
(1.47%  versus  1.54%),  it had  increased  by 16 basis points (from 1.31%) when
compared to the second quarter of 2004.

The combination of these factors  resulted in no change in the NIM for the third
quarter of 2004 (3.80%) when compared to the same quarter of 2003 and a decrease
of 4 basis points (from 3.84%) when compared to the second quarter of 2004.

Provision for Loan Losses
Trustmark's  provision  for loan losses  totaled $1.2 million and $3.9  million,
respectively,  for the three and nine months ended September 30, 2004,  compared
with $1.8 million and $7.4 million,  respectively, for the same periods in 2003.
During the nine months ended  September 30, 2004,  the provision for loan losses
equaled 97.6% of net  charge-offs  compared with 96.3% in the prior year period.
As a percentage  of average  loans,  the  provision was 0.10% for the first nine
months of 2004 compared with 0.21% for the first nine months of 2003.

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 expected  economic  conditions.  Based on
recent  improvements in economic  conditions in both national and local markets,
increased  diversification  of the loan  portfolio from a geographic and product
standpoint and continued  improvement in both underwriting and oversight of loan
processes,  Management feels that the current  provision for loan losses for the
three and nine month periods ending September 30, 2004 is sufficient to maintain
the  allowance for loan losses at an  appropriate  reserve level for present and
potential risk exposure.

Noninterest Income
Noninterest  income (NII)  consists of revenues  generated from a broad range of
banking and  financial  services.  NII totaled  $95.2  million in the first nine
months of 2004  compared  with $103.1  million in the first nine months of 2003.
NII represented  26.0% of total revenues in the first nine months of 2004 versus
27.6%  in  the  first  nine  months  of  2003.  The  comparative  components  of
noninterest  income for the nine-month periods ended September 30, 2004 and 2003
are shown in the  accompanying  table.  Noninterest  income  contributed  by the
Emerald  Coast and Allied  Houston  branch  purchases  during 2004 is considered
immaterial.

The single  largest  component  of  noninterest  income  continues to be service
charges for deposit  products and services,  which  increased  5.6% in the first
nine months of 2004 over the same period in 2003. The growth in services charges
for 2004 is  primarily  attributed  to an increase  in fees  charged for NSF and
overdrafts  combined with increased  transaction  volumes when compared with the
same time period in 2003.

Wealth management income was $15.1 million for the first nine months of 2004, an
increase of $438 thousand  when  compared  with the same period of 2003.  Wealth
management  consists  of all  income  related  to trust and  advisory  services,
including  income  generated  from  Trustmark  Securities,  Inc.  and  Trustmark
Investment Advisors,  Inc. Recent improvements in the performance of the capital
markets  positively  impacted growth in this area.  Increases in fees related to
trust and  investment  services were offset by a decrease in income derived from
annuities  during the period.  In addition,  further  integration  of the Wealth
Management  Division into Trustmark's Florida and Tennessee markets has begun to
impact  income as well.  Trustmark's  assets under  administration  decreased by
approximately  $800 million  during the third quarter of 2004 as a result of the
finalization of a corporate  bankruptcy,  which eliminated promissory notes held
in a custodial relationship. Wealth management fees related to this relationship
were   immaterial.   At  September  30,  2004,   Trustmark   held  assets  under
administration  of $6.1  billion and  remained  one of the largest  providers of
asset management services in Mississippi.

Retail  banking - other income totaled $13.5 million in the first nine months of
2004, a decrease of $331 thousand,  or 2.4%,  when compared with the same period
in 2003. Retail banking - other income consists primarily of ATM fees, fees from
the sale of checks, bank card fees and safe deposit box fees. The primary factor
in the decrease is bank card fees, which has been negatively impacted by changes
in the pricing of interchange fees.

Mortgage banking income was $6.3 million for the nine months ended September 30,
2004,  compared to $3.6  million  for the same  period of 2003.  As shown in the
accompanying   table,   mortgage  banking  income  primarily  includes  mortgage
servicing fees, gain on sale of mortgage loans,  amortization  and impairment of
mortgage  servicing rights,  guaranty fees and the valuation  adjustment on fair
value hedges used in conjunction with the mortgage servicing portfolio.  For the
nine months ended  September  30, 2004,  the primary  factor for the increase in
mortgage  banking  income is a  reduction  in  amortization  and  impairment  of
mortgage  servicing rights.  During the first nine months of 2004,  amortization
expense for mortgage  servicing rights was $9.1 million.  For the same period in
2003,  amortization  expense for mortgage  servicing  rights was $11.6  million.
During  the first  nine  months of 2004,  Trustmark  recognized  a $1.5  million
recovery  of  impairment  charges.  During the same  period of 2003,  impairment
charges of $5.0 million were recognized.  While impairment  charges increased in
the third quarter of 2004,  rising  interest rates in the second quarter of 2004
stabilized  impairment and reduced the impairment of mortgage  servicing  rights
for the nine months ended September 30, 2004. Future changes in amortization and
impairment  of mortgage  servicing  rights will  continue to be closely  tied to
fluctuations   in  long-term   mortgage   rates.   Offsetting   improvements  in
amortization  and  impairment of mortgage  servicing  rights were a reduction in
gains on sales of mortgage  loans,  which totaled $3.9 million  during the first
nine  months of 2004  compared to $12.6  million for the same period of 2003,  a
decrease  of $8.7  million.  The  overall  total of loan  sales  from  secondary
marketing  activities  declined from $1.202  billion in the first nine months of
2003 to $636.0  million  in the first  nine  months of 2004 as a  sporadic  rate
environment affected both the pricing of loans as well as the consumer demand.

noninterest income in the accompanying income statements:

Securities  gains  totaled  $21  thousand  during the first nine  months of 2004
compared  with $12.2  million  during the first nine months of 2003.  During the
first nine 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  $290.1  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.

Noninterest Expense
Trustmark's  noninterest  expense increased $2.7 million,  or 1.7%, in the first
nine months of 2004 to $165.1 million, compared with $162.3 million in the first
nine months of 2003.  Excluding  the  Emerald  Coast and Allied  Houston  branch
purchases,  noninterest  expense for the nine months  ended  September  30, 2004
would total $159.5  million.  Noninterest  expenses for the first nine months of
2003 include $6.3 million associated with Trustmark's voluntary early retirement
program. If this were eliminated, noninterest expenses for the first nine months
of 2003 would total $156.0 million.  Eliminating these adjustments,  noninterest
expense for the first nine months of 2004 increased  $3.5 million,  or 2.2% when
compared  to the same time  period in 2003.  Management  continues  to  consider
expense  control  a  major  component  of  improving   shareholder   value.  The
comparative  components  of  noninterest  expense  for  the  nine  months  ended
September 30, 2004 and 2003 are shown in the accompanying table.

Salaries and employee  benefits,  the largest  category of noninterest  expense,
decreased  $1.4  million,  or 1.4%,  in the first  nine  months of 2004 to $95.5
million,  compared with $96.9 million in the same time period in 2003. Excluding
the Emerald Coast and Allied  Houston  branch  purchases,  salaries and employee
benefits for the nine months ended September 30, 2004 would total $92.0 million.
Salaries  and  employee  benefits for the first nine months of 2003 include $6.3
million associated with Trustmark's  voluntary early retirement  program,  which
was  accepted  by 116  employees,  or  4.75%  of the  workforce.  If  this  were
eliminated,  salaries and employee benefits for the first three quarters of 2003
would total $90.6 million. Eliminating these adjustments,  salaries and employee
benefits for the first three  quarters of 2004 grew $1.4  million,  or 1.5% when
compared  to the same time  period  in 2003.  Trustmark's  full-time  equivalent
employees were 2,444 and 2,365 at September 30, 2004 and 2003, respectively.



Services  and fees for the first  nine  months  of 2004  totaled  $26.4  million
compared to $23.7  million for the first nine  months of 2003.  The  increase is
attributed  to   professional   and   audit-related   fees  resulting  from  the
implementation of requirements  under the  Sarbanes-Oxley Act of 2002 as well as
growth in consulting and communication expense.

Net  occupancy-premises  expense  increased  $1.2 million,  or 12.9%,  from $9.5
million  in the first  nine  months of 2003 to $10.8  million  in the first nine
months of 2004. The increase is attributable to occupancy costs  associated with
facilities   acquired  in  the  Emerald  Coast  and  Allied   Houston   business
combinations.  Business  combinations  accounted  for  approximately  58% of the
increase.

Income Taxes
For the nine months ended September 30, 2004, Trustmark's combined effective tax
rate was  34.5%,  compared  with 34.6% for the first  nine  months of 2003.  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.  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 September 30, 2004, these
arrangements gave Trustmark  approximately $1.114 billion in borrowing capacity,
which  approximated  the  level  at the  end of  2003.  In  addition,  Trustmark
maintains a borrowing  relationship with the FHLB, which provided $500.0 million
in short-term advances and $355.9 million in long-term advances at September 30,
2004,  compared with $300.0 million in short-term advances and $531.0 million in
long-term  advances at December 31, 2003. 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
$752.5 million  available in unused FHLB advances.  Another  borrowing source is
the Federal Reserve  Discount Window (Discount  Window).  At September 30, 2004,
Trustmark had approximately  $591.4 million  available in borrowing  capacity at
the Discount  Window from pledges of auto loans and  securities,  compared  with
$539.9 million  available at December 31, 2003. In June 2002,  Trustmark entered
into a  two-year  line  of  credit  arrangement  enabling  borrowings  up to $50
million.  When this line  matured  during the third  quarter of 2004,  Trustmark
entered  into a  revolving  credit  agreement  with  the  same  lender  enabling
borrowings  up to $50  million,  subject to certain  financial  covenants.  This
agreement matures on September 30, 2006. As of September 30, 2004, Trustmark had
not drawn upon this line of credit.

During  2003,  Trustmark  filed a  registration  statement  on Form S-3 with the
Securities  and  Exchange  Commission  (SEC)  utilizing  a "shelf"  registration
process.  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.

During 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
September 30, 2004, no such shares have been issued.


Capital Resources

At September 30, 2004,  Trustmark's  shareholders' equity was $734.2 million, an
increase of $44.7 million,  or 6.5%,  from its level at December 31, 2003.  This
increase is  primarily  related to net income for the first nine months of 2004,
which totaled  $87.9  million and  additional  accumulated  other  comprehensive
income of $1.1  million,  offset by dividends of $33.1  million and common stock
repurchases of $13.5 million.

Common Stock Repurchase Program
Trustmark currently has remaining  authorization for the repurchase of up to 3.0
million  shares of its common stock 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  18.5
million  shares for $398.6  million,  including  4,500  shares  during the third
quarter of 2004. See further  discussion of the Common Stock Repurchase  Program
on page 31 in Part II, Item 2, "Changes in Securities and Use of Proceeds".

Dividends
Another strategy  designed to enhance  shareholder  value has been to maintain a
consistent  dividend  payout  ratio,  which is  dividends  per share  divided by
earnings per share.  Dividends for the first nine months of 2004 were $ 0.57 per
share, an increase of 15.2% when compared with dividends of $ 0.495 per share in
the same period in 2003.  Trustmark's  dividend  payout ratio was 37.75% for the
first nine  months of 2004,  compared  with  33.22% for the same period in 2003.
During  October  2004,  the Board of  Directors  of  Trustmark  announced a 5.3%
increase  in its  regular  quarterly  dividend to $0.20 per share from $0.19 per
share. The Board declared the dividend payable on December 15 to shareholders of
record as of December 1, 2004. This action raises the indicated  annual dividend
rate to $0.80 per share from $0.76 per share.

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
September  30,  2004,  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 September 30, 2004, 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  accompanying  table.  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 September  30,  2004,  earning  assets were $7.468
billion,  or 91.6% of total assets,  compared with $7.183  billion,  or 90.8% of
total  assets at December  31,  2003,  an increase of $285.2  million,  or 4.0%.
Excluding the Allied  Houston  branch  purchase,  earning  assets totaled $7.350
billion, an increase of $167.6 million when compared with December 31, 2003.

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
September 30, 2004,  Trustmark's  securities  portfolio  totaled $2.063 billion,
compared to $2.112 billion at December 31, 2003, a decrease of $49.1 million, or
2.3%.

The  securities  portfolio  is a  powerful  risk  management  tool that  enables
Management to control both the invested  balance and the duration of securities.
The  estimated  duration of the  portfolio  measured 2.04 years on September 30,
2003  primarily due to expected high cash flow levels during an  environment  of
heavy  prepayments  on  mortgage  related  securities.   Since  then,  estimated
portfolio duration was measured at 2.30 years at December 31, 2003 and September
30, 2004.  Management  intends to keep the portfolio near these 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 loss, a
separate  component  of  shareholders'   equity.  At  September  30,  2004,  AFS
securities  totaled $1.916 billion,  which  represented  92.9% of the securities
portfolio,  compared to $ 1.934  billion,  or 91.6%,  at December 31,  2003.  At
September 30, 2004,  unrealized losses on AFS securities of $3.9 million, net of
$1.5  million of deferred  income  taxes,  were  included in  accumulated  other
comprehensive loss,  compared with losses of $ 5.6 million,  net of $2.1 million
in deferred  income  taxes,  at December 31, 2003.  At September  30, 2004,  AFS
securities  consisted of U.S.  Treasury and Agency  securities,  obligations  of
states  and  political  subdivisions,  mortgage  related  securities,  corporate
securities and other securities, primarily Federal Reserve Bank and FHLB stock.

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 September 30, 2004,  HTM  securities  totaled  $147.2  million and
represented 7.1% of the total portfolio,  compared with $178.4 million, or 8.4%,
at the end of 2003.  This  decline  in HTM  securities  as a  percentage  of the
securities  portfolio  should  continue as  Management  utilizes  the  increased
flexibility in AFS securities to manage its investment strategy.

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 89% of
the portfolio in U.S. Treasury,  U.S. Government agencies  obligations and other
AAA rated securities.

Loans and Allowance for Loan Losses
Loans,  including  loans held for sale,  represented  72.2% of earning assets at
September 30, 2004, compared with 70.1% at year-end 2003. At September 30, 2004,
loans totaled $5.388  billion,  a 7.1% increase from its level of $5.033 billion
at December 31, 2003.  Adjusted loan growth was $277.8 million, or 5.5%, for the
first nine months of 2004, if both the Allied  Houston  branch  purchase and the
sale of $39.6  million in  student  loans are  excluded.  Real  estate  lending,
primarily  construction  and land  development  as well as loans  secured by 1-4
family properties, continued to be positively impacted by low interest rates. In
addition,  commercial and industrial  loans have also increased when compared to
December  31,  2003,  as a result  of  improvement  in  economic  conditions  as
evidenced by growth in  Corporate  Lending as well as loans  originating  in the
Trustmark's Emerald Coast branches.

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
September 30, 2004 and December 31, 2003, are shown in the accompanying table.

Total  nonperforming  assets increased $2.1 million,  or 6.9%,  during the first
nine  months  of  2004.   Excluding  the  Allied   Houston   branch   purchases,
nonperforming assets decreased $3.3 million, or 11.2%. The allowance coverage of
nonperforming  loans remains  strong at 274.1% at September  30, 2004,  compared
with 310.5% at December 31, 2003.

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

At September 30, 2004, the allowance for loan losses was $74.2 million  compared
with  $74.3  million  at  December  31,  2003.  The  allowance  for loan  losses
represented 1.38% of total loans outstanding at September 30, 2004,  compared to
1.48% at December 31, 2003.  This  decline in the  allowance  for loan losses to
loans is directly related to the accounting  treatment for the acquired loans of
Allied Houston Bank.  Generally accepted accounting  principles provide that the
purchase of selected loans be recorded at fair value net of any credit or market
discounts;  therefore,  no specific  allowance for loan losses has been recorded
for the Allied Houston loans purchased.  Loans purchased totaled $145.9 million,
which  included a $6.4 million  discount;  consisting  of a discount for general
credit risk of $7.3 million offset by a market  premium of $862 thousand.  As of
September  30, 2004,  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 $4.0 million, or 0.10% of average loans, for the first nine
months of 2004,  compared with $7.7 million,  or 0.22% of average loans, for the
same  period of 2003.  This  improvement  can  primarily  be  attributed  to the
continued  decline  in  charge-offs  recorded  during  2004  resulting  from the
improvement in credit quality experienced during 2003 and 2004.

Other Earning Assets
Federal funds sold and securities purchased under reverse repurchase  agreements
were $16.3  million at  September  30,  2004,  a decrease of $21.4  million when
compared with year-end 2003.  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
interest-bearing and noninterest-bearing demand accounts, savings, money market,
certificates of deposit, individual retirement accounts and brokered CD's. Total
deposits were $5.288 billion at September 30, 2004, compared with $5.089 billion
at December 31, 2003,  an increase of $198.1  million,  or 3.9%.  Excluding  the
Allied Houston branch purchase,  deposits increased $62.9 million, or 1.2%, when
compared with December 31, 2003.  Noninterest  bearing  deposits have  decreased
$86.8  million  during the first nine  months of 2004 due to  seasonal  run-offs
while  interest-bearing  deposits have increased  $284.9 million during the same
time  period.  During  2003,  Trustmark  began a brokered  CD program to provide
additional deposit funding.  At September 30, 2004, brokered CD's totaled $236.9
million,  an  increase  of  $137.9  million  when  compared  to the end of 2003.
Additional  growth in  interest-bearing  deposits may be attributed to uncertain
financial  market  conditions,  which  have lead to more  growth in  traditional
deposit  products  such as  interest-bearing  demand  deposits.  Trustmark  will
continue to seek deposits by expanding its presence in higher growth markets and
evaluating additional wholesale deposit funding sources.

Trustmark uses short-term  borrowings and long-term FHLB advances to fund growth
of earning assets in excess of deposit growth.  Short-term borrowings consist of
federal funds purchased, securities sold under repurchase agreements, short-term
FHLB  advances  and the treasury  tax and loan note option  account.  Short-term
borrowings  totaled  $1.710 billion at September 30, 2004, an increase of $160.0
million,  compared with $1.550 billion at year-end 2003. Long-term FHLB advances
totaled  $355.9 million at September 30, 2004, a decrease of $175.1 million from
December 31, 2003. On a  consolidated  basis,  total  borrowings  have decreased
$15.1 million when compared to December 31, 2003.


Segment Information

Internal funding costs for both the General Banking and Administrative divisions
saw significant  changes when both the three and nine months ended September 30,
2004  are  compared  with  the  same  periods  in  2003.  As part of the  annual
evaluation of the match-funded transfer pricing process used to assess operating
segment  performance,  Management  lowered  the  internal  funding  rate paid on
transactional  deposits,  primarily Savings, MMDA, NOW and DDA, at the beginning
of 2004.  This  reduction  was based on a downward  trend in yields and earnings
generated  from these  deposits in recent  years.  The impact of this change was
felt primarily in the General Banking Division where internal funding income was
reduced when 2004 is compared with 2003. Additionally,  the Treasury Department,
included in the Administrative  Division,  received  additional internal funding
income resulting from these same changes.

Legal Environment

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 during 2003 and 2004 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;  however,
Management  is unable to  estimate a range of  potential  loss on these  matters
because  of the  nature  of the legal  environment  in  states  where  Trustmark
conducts business.

Off-Balance Sheet Arrangements

Trustmark  makes  commitments to extend credit and issues standby and commercial
letters  of credit in the normal  course of  business  in order to  fulfill  the
financing needs of its customers.  These loan  commitments and letters of credit
are off-balance sheet arrangements.

Commitments to extend credit are agreements to lend money to customers  pursuant
to certain  specified  conditions.  Commitments  generally have fixed expiration
dates or other termination clauses. Since many of these commitments are expected
to expire  without  being  drawn  upon,  the  total  commitment  amounts  do not
necessarily  represent  future  cash  requirements.  Trustmark  applies the same
credit  policies  and  standards  as it does in the lending  process when making
these  commitments.   The  collateral   obtained  is  based  upon  the  assessed
creditworthiness of the borrower.  At September 30, 2004 and 2003, Trustmark had
commitments to extend credit of $1.344 billion and $1.131 billion, respectively.

Standby and commercial  letters of credit are conditional  commitments issued by
Trustmark to insure the performance of a customer to a third party. When issuing
letters of credit, Trustmark uses essentially the same policies regarding credit
risk and collateral which are followed in the lending process.  At September 30,
2004 and 2003,  Trustmark's  maximum  exposure  to  credit  loss in the event of
nonperformance  by the other party for  letters of credit was $95.5  million and
$76.7 million, respectively. These amounts consist primarily of commitments with
maturities  of less than three  years.  Trustmark  holds  collateral  to support
certain letters of credit when deemed necessary.



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.

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.

Based on the results of the simulation models using static balances at September
30, 2004,  it is estimated  that net interest  income may increase  0.29%,  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 same  simulation as of
June 30, 2004  yielded a decrease in net  interest  income of 0.19%.  This minor
change in forecasted net interest income  illustrates  Management's  strategy to
mitigate  Trustmark's  exposure to cyclical  increases in rates by maintaining a
neutral  position in its interest rate risk position.  This  projection does not
contemplate  any additional  actions  Trustmark  could undertake in responses to
changes  in  interest  rates.  In the event of a 100  basis  point  decrease  in
interest rates  (utilized in place of a 200 basis point drop scenario due to the
historically low interest rate environment), it is estimated net interest income
may decrease by 3.08%.  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  2004.  Management  will
continue to prudently  manage the balance sheet in an effort to control interest
rate risk and maintain profitability over the long term.



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.  Management feels that this method for analyzing  interest
rate sensitivity does not provide a complete picture of Trustmark's  exposure to
interest rate changes  since it  illustrates a  point-in-time  measurement  and,
therefore,  does not  incorporate  the effects of future  balance  sheet trends,
repricing  behavior  of  certain  deposit  products  or  varying  interest  rate
scenarios. This analysis is a relatively straightforward tool that is helpful in
highlighting  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 September
30, 2004,  reflected a liability  gap of $372 million  compared with a liability
gap of  $470  million  at May 31,  2004.  One-year  gap  analysis  projected  at
September 30, 2004,  reflected a liability  gap of $303 million  compared with a
liability  gap of  $466  million  at May 31,  2004.  Liability  sensitivity  has
resulted from Trustmark's increased reliance on wholesale funding during 2004 in
response to decreased  funding from deposits.  This scenario would indicate that
Trustmark would benefit in a falling  interest rate  environment,  however,  the
simulation model indicates repricing  sensitivity on various deposit products is
different  when compared with a static gap  analysis.  For example,  traditional
core deposit products typically are slower to react to changes in interest rates
when they occur.

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.  As permitted by
Statement  of  Financial  Accounting  Standards  (SFAS)  No.  133,  during  2003
Trustmark  redesignated  these derivative  instruments as fair value hedges.  In
accordance with SFAS No. 133, changes in the values of derivatives designated as
fair value hedges are recognized in earnings. In this case, Trustmark recognizes
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.  Management  anticipates  that this change will
help mitigate the potential for earnings  volatility related to the valuation of
these hedging  instruments in the future. The market valuation balance for these
fair value hedges was negative $502.6 thousand at September 30, 2004.

Trustmark continued a risk controlling strategy utilizing caps and floors, which
may be further  implemented  over time. As of September 30, 2004,  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.  At September  30, 2004,  the fair value of these  contracts  was $43
thousand.

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.  These swaps are designated as fair value hedges.  Trustmark  initiated
these  swaps to  mitigate  the  effects of further  changes in the fair value of
specific  noncallable,  fixed rate  advances  from the FHLB by agreeing to pay a
floating  interest rate tied to LIBOR.  Although this strategy exposes Trustmark
somewhat to a rising rate environment,  Management felt this was more economical
in light of the significant  prepayment  charges associated with these advances.
The swap  contracts  are tied to the  maturity of five  separate  FHLB  advances
maturing between 2005 and 2006. The market  valuation  balance for interest rate
swaps at September 30, 2004 was negative $676 thousand.
