                      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 six month
periods ended June 30, 2005, are not necessarily  indicative of the results that
may be expected for the year ended December 31, 2005. The notes included  herein
should  be read in  conjunction  with the  notes to the  consolidated  financial
statements included in Trustmark Corporation's (Trustmark) 2004 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 December 1, 2004, Trustmark acquired Fisher-Brown,  Incorporated,  located in
Pensacola,  Florida.  This  business  combination  was  accounted  for under the
purchase  method of  accounting.  Excess cost over tangible net assets  acquired
totaled  $36.2  million,  of which  $9.3  million  and $26.9  million  have been
allocated to identifiable intangible assets and goodwill, respectively.

On March 12, 2004,  Trustmark acquired five branches of Allied Houston Bank in a
business  combination  accounted for by the purchase  method of  accounting.  In
connection with the transaction, Trustmark acquired approximately $148.1 million
in assets and assumed $161.7 million in deposits and other liabilities for a $10
million deposit  premium.  Assets consisted of $145.9 million 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.  The
purchase price was finalized  during the first quarter of 2005 after  completion
of an  evaluation  of the  adequacy  of the  discount  for  general  credit risk
mentioned above. The resulting adjustment was immaterial.

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.

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

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 net
servicing income. At June 30, 2005,  Trustmark serviced $3.5 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 2004, Trustmark  reclassified $7.1 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.

Improved coverage of sweep eligible accounts  resulting from the  implementation
of a  third-party  software  product  was the  primary  factor in an increase in
savings  accounts,  which have no reserve  requirement as defined by the Federal
Reserve Bank,  and a resulting  decline in  transaction  based  interest-bearing
demand deposits and noninterest-bearing demand deposits.

NOTE 6 - STOCK-BASED COMPENSATION

On May 10, 2005,  the  shareholders  of Trustmark,  upon the  recommendation  of
Trustmark's  Board of Directors,  approved the Trustmark  Corporation 2005 Stock
and Incentive  Compensation Plan (the 2005 Plan), which was adopted by the Board
of Directors,  and replaces the Trustmark  Corporation  1997 Long Term Incentive
Plan (the 1997 Plan).  The 2005 Plan became  effective May 10, 2005, and subject
to earlier termination by the Board of Directors, terminates on May 9, 2015. The
2005 Plan  allows  Trustmark  to make  grants of  non-qualified  stock  options,
incentive stock options, stock appreciation rights, restricted stock, restricted
stock units and performance  units to key associates and directors.  The maximum
number of shares of  Trustmark's  common stock  available for issuance under the
2005  Plan is the sum of (1)  6,000,000  common  shares  plus (2) the  number of
outstanding  options  under  the  1997  Plan,  which  expire  or  are  otherwise
terminated or forfeited after May 10, 2005.

Effective  January  1,  2003,  Trustmark  adopted  the  fair  value  recognition
provisions  of  Statement  of  Financial  Accounting  Standard  (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. Compensation expense for stock
options  granted is estimated  using the fair value of each option granted using
the  Black-Scholes  option-pricing  model.  Compensation  expense for restricted
stock granted is recorded over the service period based on the fair value of the
underlying  common stock on the date of grant based on the number of  restricted
shares expected to vest.

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

NOTE 7 - CONTINGENCIES

Letters of Credit
Standby and commercial  letters of credit are conditional  commitments issued by
Trustmark to insure the  performance  of a customer to a third party.  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.  A
financial  standby  letter of credit  irrevocably  obligates  Trustmark to pay a
third-party  beneficiary  when a customer fails to repay an outstanding  loan or
debt instrument.  A performance  standby letter of credit irrevocably  obligates
Trustmark to pay a third-party beneficiary when a customer fails to perform some
contractual,  nonfinancial obligation. 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, 2005 and 2004,  Trustmark's  maximum  exposure to credit loss in the
event of nonperformance by the other party for standby and commercial letters of
credit was $114.5 million and $91.4 million, respectively. These amounts consist
primarily of commitments with maturities of less than three years, which have an
immaterial carrying value. Trustmark holds collateral to support standby letters
of  credit  when  deemed  necessary.  As of June 30,  2005,  the  fair  value of
collateral held was $26.0 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 - BENEFIT PLANS

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 the length of credited service and
final average compensation as defined in the plan. Trustmark's policy is to fund
amounts allowable as deductions for federal income tax purposes.

pension costs for the six months ended June 30, ($ in thousands):

Supplemental Retirement Plan
Trustmark  maintains  a  non-qualified  supplemental  retirement  plan  covering
directors that elect to defer fees, key executive  officers and senior officers.
The plan provides for defined death benefits and/or retirement benefits based on
a participant's covered salary.  Trustmark has acquired life insurance contracts
on the  participants  covered  under the plan  which may be used to fund  future
payments.

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 potentially 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:

For the quarters  ended June 30, 2005 and 2004,  options to purchase 1.0 million
and 767 thousand shares, respectively, were outstanding, but not included in the
computation of diluted earnings per share because they were antidilutive.




NOTE 10 - STATEMENTS OF CASH FLOWS

Trustmark  paid income taxes of $22.4 million and $21.2  million  during the six
months  ended June 30,  2005 and 2004,  respectively.  Interest  paid on deposit
liabilities  and other  borrowings  approximated  $45.8 million in the first six
months of 2005 and $40.8  million in the first six  months of 2004.  For the six
months ended June 30, 2005 and 2004,  noncash transfers from loans to foreclosed
properties  were $1.1 million and $3.3 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 six months of 2005,  $75.0 million of long-term  FHLB
advances were converted to short-term  borrowings  compared with  conversions of
$150.0 million in the first six months of 2004.

NOTE 11 - RECENT PRONOUNCEMENTS

In May 2005,  the Financial  Accounting  Standards  Board (FASB) issued SFAS No.
154,  "Accounting  Changes and Error Corrections." SFAS No. 154 is a replacement
of APB No.  20,  "Accounting  Changes"  and FASB  Statement  No.  3,  "Reporting
Accounting  Changes in Interim Financial  Statements." SFAS No. 154 establishes,
unless  impracticable,  retrospective  application  as the  required  method for
reporting a change in accounting principle in the absence of explicit transition
requirements specific to the newly adopted accounting principle.  This statement
applies to voluntary changes in accounting principle as well as changes required
by an accounting  pronouncement that provide no specific transition  provisions.
This  statement is effective for  accounting  changes and  corrections of errors
made in fiscal years  beginning  after  December  15, 2005.  The effects of this
statement are not expected to have a material impact on Trustmark's statement of
position or results of operations.

In December  2004,  the FASB issued a revision of SFAS No. 123 (SFAS No.  123r),
"Share-Based  Payment." This  statement  revises SFAS No. 123,  "Accounting  for
Stock-Based  Compensation,"  and supersedes APB Opinion No. 25,  "Accounting for
Stock  Issued  to  Employees."  SFAS  No.  123r  establishes  standards  for the
accounting for transactions in which a company exchanges equity  instruments for
goods or  services.  This  statement  requires  companies to measure the cost of
employee services received in exchange for an award of equity  instruments based
on the grant-date  fair value of the award.  As of the required  effective date,
public companies using the fair-value-based method for recognition or disclosure
under  SFAS No.  123,  will  apply this  statement  using a modified  version of
prospective  application.  Trustmark  adopted  the  provisions  of SFAS No.  123
effective January 1, 2003; therefore, Trustmark will recognize compensation cost
for the portion of  outstanding  awards for which the requisite  service has not
yet been rendered  (unvested  awards).  For public companies,  this statement is
effective as of the  beginning of the first annual  reporting  period  beginning
after June 15, 2005.  The effects of this  statement  are not expected to have a
material impact on Trustmark's statement of position or results of operations.

NOTE 12 - SEGMENT INFORMATION

Trustmark's  management  reporting  structure  includes four  segments:  general
banking,  wealth management,  insurance and  administration.  General banking is
responsible for all traditional  banking products and services,  including loans
and  deposits.  Wealth  management  provides  customized  solutions for affluent
customers by integrating  financial  services with traditional  banking products
and services such as private banking, money management,  full-service brokerage,
financial  planning,  risk  management,  personal and  institutional  trust, and
retirement services.  Wealth management includes three wholly-owned subsidiaries
of TNB: Trustmark  Securities,  Inc., Trustmark  Investment Advisors,  Inc., and
TRMK Risk Management,  Inc. Insurance includes two wholly-owned  subsidiaries of
TNB: The  Bottrell  Insurance  Agency and  Fisher-Brown,  Incorporated.  Through
Bottrell,  Trustmark  provides  a  full  range  of  retail  insurance  products,
including  commercial  risk  management  products,  bonding,  group benefits and
personal lines  coverages.  Fisher-Brown  operates as a  full-service  insurance
agency, selling a broad spectrum of insurance services.  Administration includes
all other  activities  that are not  directly  attributable  to one of the major
lines of business.  Administration consists of internal operations such as Human
Resources,  Executive  Administration,   Property  Management,  Treasury  (Funds
Management) and Corporate Finance.

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.  Noninterest
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 June 30, 2005 and 2004.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS

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 and
encompass   any  estimate,   prediction,   expectation,   projection,   opinion,
anticipation,  outlook or  statement of belief  included  therein as well as the
management assumptions underlying these forward-looking  statements.  Should one
or more of these risks  materialize,  or should any such underlying  assumptions
prove to be significantly different,  actual results may vary significantly from
those  anticipated,  estimated,  projected or expected.  These risks could cause
actual results to differ materially from current  expectations of Management and
include the following:

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

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

OVERVIEW

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 through over 145 offices and 2,616 associates  predominantly
within the states of Florida, Mississippi, Tennessee and Texas.



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

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

Net income for the three  months  ended June 30,  2005 and 2004,  totaled  $22.2
million and $33.0 million,  respectively.  Basic and diluted  earnings per share
were $0.39 for the second  quarter of 2005,  compared  with $0.57 for the second
quarter of 2004.  Earnings during the second quarter of 2005 included a pre-tax,
non-cash  charge of $4.8 million for  impairment of the home mortgage  servicing
portfolio  related to declines in long-term  interest  rates during the quarter.
Also included in earnings for the second  quarter of 2005 is a pre-tax charge of
$4.1  million  related to the sale of  certain  investment  securities.  See the
section captioned  "Noninterest Income" elsewhere in this discussion for further
analysis of these  items.  Net income for the six months ended June 30, 2005 and
2004, totaled $49.0 million and $59.8 million,  respectively.  Basic and diluted
earnings  per share for the six months  ended June 30, 2005 were $0.86  compared
with basic  earnings per share of $1.03 and diluted  earnings per share of $1.02
for the six months ended June 30, 2004.  At June 30,  2005,  Trustmark  reported
gross loans,  including loans held for sale, of $5.790 billion,  total assets of
$8.104  billion,  total deposits of $5.521 billion and  shareholders'  equity of
$744.6 million.

Management  utilizes certain financial ratios to gauge Trustmark's  performance.
Trustmark  achieved a return on average  assets of 1.08% and a return on average
equity of 11.84% for the three months ended June 30, 2005.  These  compared with
ratios of 1.61% for  return on  average  assets and 18.51% for return on average
equity for the three months  ended June 30, 2004.  For the six months ended June
30, 2005, Trustmark achieved a return on average assets of 1.21% and a return on
average  equity of 13.13%.  These compare to a return on average assets of 1.49%
and a return on average equity of 16.91% for the same periods of 2004.

CRITICAL ACCOUNTING POLICIES

Trustmark's  consolidated  financial  statements are prepared in accordance with
accounting  principles  generally  accepted in the United  States of America and
follow general practices within the financial services industry.  Application of
these accounting  principles requires management to make estimates,  assumptions
and judgments  that affect the amounts  reported in the  consolidated  financial
statements and accompanying  notes.  These estimates,  assumptions and judgments
are based on information available as of the date of the consolidated  financial
statements;  accordingly,  as this information changes, actual financial results
could differ from those estimates.

Certain  policies  inherently  have a greater  reliance on the use of estimates,
assumptions and judgments and, as such, have a greater  possibility of producing
results that could be  materially  different  than  originally  reported.  These
critical accounting policies are described in detail below.

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


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 value.  Mortgage
servicing  rights are  amortized  over the  estimated  period of the related net
servicing income.

Mortgage  servicing  rights are evaluated  quarterly for impairment.  Impairment
occurs when the estimated fair value falls below the underlying  carrying value.
For  purposes  of  evaluating  impairment,  Trustmark  stratifies  its  mortgage
servicing portfolio on the basis of certain risk characteristics  including loan
type, term and note rate. Changes in interest rates,  prepayment speeds or other
factors  could  result  in  impairment  or  recovery  of  the  servicing  asset.
Impairment or impairment  recovery is recognized  through a valuation  allowance
with a corresponding charge to mortgage banking noninterest income.

Benefit Plans
Benefit plan assets,  liabilities  and pension  costs are  determined  utilizing
actuarially present value calculations.  The valuation of the benefit obligation
and net periodic expense is considered  critical,  as it requires Management and
its actuaries to make estimates regarding the amount and timing of expected cash
outflows including  assumptions about mortality,  expected service periods, rate
of  compensation  increases  and the long-term  return on plan assets.  Note 8 -
Benefit Plans, included in the accompanying Notes to the Consolidated  Financial
Statements,  provides  further  discussion  on the  accounting  for  Trustmark's
benefit plans (pension and supplemental  retirement plan) and the estimates used
in determining  the actuarial  present value of the benefit  obligations and the
net periodic benefit expense.

Fair Value Accounting Estimates
Generally  accepted  accounting  principles  require  the use of fair  values in
determining  the  carrying  values of  assets  and  liabilities,  as well as for
specific  disclosures.  The  most  significant  include  securities,  derivative
instruments,  loans  held for sale,  mortgage  servicing  rights  and net assets
acquired  in a  business  combination.  Certain  of these  assets  do not have a
readily  available  market to determine fair value and require an estimate based
on specific parameters. When market prices are unavailable, Trustmark determines
fair values  utilizing  parameters,  which are  constantly  changing,  including
interest rates,  duration,  prepayment speeds and other specific conditions.  In
most cases,  these specific  parameters require a significant amount of judgment
by Management.

Contingent Liabilities
Trustmark estimates contingent  liabilities based on Management's  evaluation of
the probability of outcomes and their ability to estimate the range of exposure.
As  stated  by  Statement  of  Financial  Accounting  Standards  (SFAS)  No.  5,
"Accounting for  Contingencies,"  a liability is contingent if the amount is not
presently  known,  but  may  become  known  in the  future  as a  result  of the
occurrence of some uncertain future event.  Accounting  standards require that a
liability be recorded if Management  determines  that it is probable that a loss
has occurred and the loss can be reasonably  estimated.  In addition, it must be
probable  that the loss will be confirmed by some future  event.  As part of the
estimation  process,  Management is required to make  assumptions  about matters
that are, by their  nature,  highly  uncertain.  The  assessment  of  contingent
liabilities,  including legal contingencies and income tax liabilities, involves
the use of critical estimates, assumptions and judgments. Management's estimates
are  based  on their  belief  that  future  events  will  validate  the  current
assumptions  regarding the ultimate outcome of these exposures.  However,  there
can be no  assurance  that future  events,  such as court  decisions or Internal
Revenue  Service  positions,  will not  differ  from  Management's  assessments.
Whenever  practicable,  Management  consults  with outside  experts  (attorneys,
independent  accountants,  claims  administrators,  etc.)  to  assist  with  the
gathering and evaluation of information related to contingent liabilities.

BUSINESS COMBINATIONS

Trustmark's  strategic  acquisition  program  is based on  efforts  to  evaluate
opportunities  to expand and  invest in  higher-growth  markets by  implementing
market-specific  business  initiatives.  This  approach  is designed to maximize
financial profitability, bolster growth prospects and enhance shareholder value.
In the first  quarter of 2004,  Trustmark  entered the dynamic  Houston  banking
market with the purchase of five branch  offices from Allied  Houston Bank.  The
Houston MSA is among the largest and highest-growth  markets in the country.  In
December 2004, Trustmark continued to expand insurance services,  as well as its
presence  in the  Florida  Panhandle,  with  the  acquisition  of  Fisher-Brown,
Incorporated,  Northwest  Florida's leading  insurance agency,  headquartered in
Pensacola,  with offices in Milton,  Mary Esther,  Destin and Panama City.  This
transaction enhances  Trustmark's  strategic goal of becoming a more diversified
financial  services  organization.   For  more  information  on  these  business
combinations,  please refer to Note 2 of the Notes to the Consolidated Financial
Statements.

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  accompanying  Yield/Rate
Analysis  Table 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.

Net  interest  income-FTE  for the  three-month  and  six-month  periods of 2005
decreased $1.6 million,  or 2.3%, and $1.7 million,  or 1.2%, when compared with
the same  periods of 2004.  Increases  in the target fed funds rate of 225 basis
points throughout 2004 and the first half of 2005 resulted in increased interest
income-FTE  and interest  expense.  While interest  expense on  interest-bearing
liabilities,  primarily  federal  funds  purchased,  repurchase  agreements  and
borrowings,  increased substantially, the increase in interest income on earning
assets was sufficient to offset the additional interest expense. The combination
of these factors  resulted in a nominal decline in the NIM during the six months
ended June 30,  2005 of 6 basis  points  when  compared  with the same period of
2004.  For  additional  discussion,  see  Market/Interest  Rate Risk  Management
included later in the Management's Discussion and Analysis.

Average  interest-earning assets for the first half of 2005 were $7.385 billion,
compared  with $7.347  billion for the first half of 2004,  an increase of $37.8
million,  or 0.5%.  Without the Allied Houston branch purchase,  the increase in
average  interest-earning assets for the first half of 2005 is $11.8 million, or
0.2%.  Growth in average loans for the first half of 2005,  which increased 7.8%
(7.3% without  Allied  Houston)  when compared with the first half of 2004,  was
offset by a decrease in average securities, which decreased 17.6% when the first
six  months of 2005 and 2004 are  compared.  Since the  fourth  quarter of 2003,
Management has been adjusting the balance sheet in  anticipation  of the risk of
rising rates. This strategy has been well founded as short-term rates have risen
225 basis  points  over that  time  period.  However,  the  upward  shift in the
short-term  rates without a  proportionate  upward shift in long-term  rates has
diminished the profitability of holding long-term assets. If ignored, persistent
interest rate behavior of this nature could lead to significant  negative impact
on margin.  In  preparation  for potential  adverse risks to margin,  Management
implemented  a strategy  of exiting  certain  assets and  reducing  balances  of
funding  sources that would bear the highest  costs in such a rate  environment.
This  began in the  fourth  quarter  of 2004,  with the sale of $304  million in
mortgage-related  and U. S. Treasury  securities and continued during the second
quarter of 2005 when Trustmark sold $256 million in U. S. Government  Agency and
U. S. Treasury securities. Projected funding costs to carry these investments to
their  remaining  maturity may have generated a greater  negative  margin impact
than the actual losses incurred at sale. Proceeds from sales were used to reduce
balances of higher-cost  funding  sources.  The rising interest rate environment
positively impacted yields as the yield on average earning assets increased from
5.00%  during  the first  half of 2004 to 5.48% for the first  half of 2005,  an
increase of 48 basis points.  The  combination  of these factors  resulted in an
increase  in  interest  income-FTE  during the first six months of 2005 of $18.1
million, or 9.9%, when compared with the first six months of 2004.

Average  interest-bearing  liabilities for the first half of 2005 totaled $6.081
billion, compared with $6.049 billion for the first half of 2004, an increase of
$31.1 million,  or 0.5%.  Without the Allied Houston  branch  purchase,  average
interest-bearing liabilities for the first half of 2005 decreased $11.6 million,
or 0.2%. Average  interest-bearing  deposits and short-term borrowings increased
during the first six months of 2005,  which offset  decreases  in federal  funds
purchased,  repurchase  agreements  and long-term  FHLB advances  resulting from
liquidity  created  from the sale of  securities  mentioned  above.  The  rising
interest  rate  environment   negatively  impacted  yields  on  interest-bearing
liabilities as seen in the increase in rates on interest-bearing  deposits of 31
basis points,  federal funds  purchased and  repurchase  agreements of 147 basis
points as well as the increase in rates on  borrowings  of 140 basis points when
the  first  six  months  of 2005 and 2004 are  compared.  The  average  rates on
interest-bearing  liabilities for the first half of 2005 and 2004 were 2.00% and
1.34%, respectively, representing an increase of 66 basis points during 2005. As
a result of these factors,  total  interest  expense for the first six months of
2005 increased $19.8 million,  or 48.9%, when compared with the first six months
of 2004.

Provision for Loan Losses
The  provision  for loan losses is  determined  by  Management  as the amount to
adjust the allowance for loan losses to a level,  which,  in  Management's  best
estimate,  is  necessary to absorb  probable  losses  within the  existing  loan
portfolio. The provision for loan losses for the three and six months ended June
30, 2005,  totaled $1.4 million and $4.2  million,  respectively,  compared with
$1.7 million and $2.8 million,  respectively,  for the same periods of 2004. The
increase for the six months ended June 30, 2005,  is primarily  the result of an
additional  provision  of $1.9  million  related to a single  commercial  credit
recognized  during the first quarter of 2005. As a percentage of average  loans,
the provision was 0.15% for the first half of 2005 and 0.11% for the same period
of 2004.  See the  section  captioned  "Loans  and  Allowance  for Loan  Losses"
elsewhere in this  discussion  for further  analysis of the  provision  for loan

Noninterest  income (NII)  consists of revenues  generated from a broad range of
banking  and  financial  services.  NII totaled  $64.5  million in the first six
months of 2005 compared with $64.9 million in the first six months of 2004.  The
comparative components of noninterest income for the six months ended June 30,
2005 and 2004 are shown in the accompanying table.

The single  largest  component  of  noninterest  income  continues to be service
charges for deposit products and services, which decreased 5.0% in the first six
months of 2005 over the same period in 2004. The primary reason for the decrease
in service  charges is a decline in fees earned on deposit  accounts as a result
of  increased  usage of accounts  that do not charge a monthly  service  fee. An
additional  component of this decrease  relates to increases in earnings credits
earned  by  commercial  depositors  as a  result  of the  rising  interest  rate
environment, which has negatively impacted the overall service charges earned on
these accounts.

Insurance  commissions  were  $16.2  million  in the first  six  months of 2005,
compared  with $7.5 million in the first six months of 2004, an increase of $8.7
million or 115.5%. The increase in insurance commissions is primarily due to the
Fisher-Brown  acquisition,  which occurred during the fourth quarter of 2004 and
contributed approximately $8.5 million, or 98% of the increase.

Wealth  management income was $10.7 million during the first six months of 2005,
compared with $10.0 million in the first six months of 2004.  Wealth  management
consists of income  related to trust and  advisory  services,  including  income
generated from Trustmark  Securities,  Inc. and Trustmark  Investment  Advisors,
Inc. The growth in wealth management income is largely attributed to an increase
in trust fee income  resulting from new account  growth,  asset  appreciation on
existing  accounts and changes in the fee structure  related to certain  managed
accounts.  In addition,  the increased  presence of wealth  management  teams in
Florida, Houston and Memphis and the creation of the Wealth Management Center in
Jackson have begun to positively impact income. At June 30, 2005, 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  totaled $10.0 million for the six months ended June 30,
2005, an increase of $1.2 million,  or 13.8%, when compared with the same period
of 2004. Retail banking - other income consists primarily of ATM fees, fees from
the sale of checks,  bank card fees and safe deposit box fees.  This growth is a
result of increased  fees  related to  electronic  transactions  such as ACH and
debit card transactions resulting from increased transaction volume.

Mortgage  banking  income  was $605  thousand  for the first six months of 2005,
compared  to $7.2  million  for the  first six  months of 2004.  As shown in the
accompanying  table,  net  mortgage  servicing  income  has  remained  constant,
resulting from consistent  balances in the mortgage servicing  portfolio.  Loans
serviced  for others  totaled $3.5 billion and $3.4 billion at June 30, 2005 and
2004,  respectively.  As a result, the factors that drive the change in mortgage
banking  income are  primarily  those  factors that are  sensitive to changes in
interest rates such as amortization and impairment of mortgage  servicing rights
as well as gains on sales of loans.

For the first  six  months of 2005,  the  primary  factor  for the  decrease  in
mortgage banking income is an increase of $6.7 million in impairment of mortgage
servicing rights resulting from declines in long-term  interest rates during the
second quarter.  This non-cash charge against income could be reversed, in whole
or in part, if long-term interest rates rise, refinancing slows and the expected
life of home mortgages lengthens. Amortization expense decreased to $5.2 million
for the first six months of 2005 when  compared  with $6.4  million for the same
period in 2004, as the expected life of the portfolio has lengthened in response
to a rise in interest rates from the  historically  low environment of the first
quarter of 2004.  Future  changes in  amortization  and  impairment  of mortgage
servicing  rights will continue to be closely tied to  fluctuations in long-term
mortgage  rates.  Gain on sales of loans  decreased from $2.3 million during the
six months ended June 30,  2004,  to $708  thousand  during the six months ended
June  30,  2005.  The  overall  total of loan  sales  from  secondary  marketing
activities  declined from $426.9 million during the first half of 2004 to $415.1
million  in the first  half of 2005.  The  volatile  interest  rate  environment
experienced  during 2005 has  presented  fewer gain on sale  opportunities  when
compared to the first half of 2004.

noninterest income in the accompanying income statements.

Securities  losses  totaled  $4.1  million  during the six months ended June 30,
2005,  compared with securities  gains of $15 thousand during the same period of
2004. The losses for the six months ended June 30, 2005, primarily resulted from
the sale of $256 million in U.S.  Government Agency and U.S. Treasury securities
during the second quarter of 2005. The sale of these securities resulted from an
intentional   reduction  in  the  investment  portfolio  due  to  the  declining
profitability  of holding  longer-term  investment  securities.

Noninterest Expense
Trustmark's  noninterest expense increased $12.7 million, or 11.7%, in the first
six months of 2005 to $121.4  million,  compared with $108.7 million in the same
period of 2004. Excluding the Fisher-Brown acquisition and Allied Houston branch
purchase,  noninterest  expense  for the first six  months of 2005  would  total
$112.8  million,  an increase of $5.3 million,  or 4.9%,  compared with the same
period  of 2004.  Management  continues  to  consider  expense  control  a major
component  of  improving  shareholder  value.  The  comparative   components  of
noninterest expense for the six months ended June 30, 2005 and 2004 are shown in
the accompanying table.

Salaries and employee  benefits,  the largest  category of noninterest  expense,
were $74.6 million for the first six months of 2005, compared with $64.1 million
for the same  period of 2004.  Business  combinations,  primarily  Fisher-Brown,
accounted  for  58%  of  the  increase.  Eliminating  adjustments  for  business
combinations,  salaries and employee  benefits for the six months ended June 30,
2005, grew $5.3 million,  or 8.3%, when compared to the same time period in 2004
primarily  from merit  salary  increases  as well as salaries  and  benefits for
additional   employees  added  as  Trustmark  continues  to  consider  that  its
investment  in people is one of the critical  components  of adding  shareholder
value.  Trustmark's  full-time equivalent employees were 2,616 and 2,465 at June
30, 2005 and 2004, respectively.

During the first six months of 2005, net  occupancy-premises  expense  increased
$622  thousand,  or  9.2%.  The  increase  during  the  first  half  of  2005 is
attributable  to occupancy  costs  associated  with  facilities  acquired in the
Fisher-Brown   acquisition   and  Allied  Houston  branch   purchase.   Business
combinations  accounted for approximately 80% of the increase.  The increase was
also the result of additional maintenance on existing premises.



Equipment  expense  totaled $7.8 million for the six months ended June 30, 2005,
compared  with $7.3  million  for the same  period of 2004,  an increase of $485
thousand or 6.6%.  The increase is a result of additional  costs related to data
processing and depreciation of office equipment. Business combinations accounted
for approximately 40% of the increase.

Income Taxes
For the six months ended June 30, 2005,  Trustmark's combined effective tax rate
was 34.8%,  compared  with  34.5% for the first six  months of 2004.  The slight
increase in Trustmark's effective tax rate for 2005 is due to immaterial changes
in permanent items as a percentage of pretax income.

LIQUIDITY

Liquidity is the ability to meet asset funding requirements and operational cash
outflows in a timely  manner,  in  sufficient  amount and without  excess  cost.
Consistent  cash flows from operations and adequate  capital provide  internally
generated liquidity.  Furthermore,  Management maintains funding capacity from a
variety of external sources to meet daily funding needs,  such as those required
to meet  deposit  withdrawals,  loan  disbursements  and  security  settlements.
Liquidity strategy also includes the use of wholesale funding sources to provide
for the  seasonal  fluctuations  of deposit  and loan  demand  and the  cyclical
fluctuations of the economy that impact the  availability  of funds.  Management
keeps excess funding  capacity  available to meet potential  demands  associated
with adverse circumstances.

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.  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, 2005,  Trustmark
estimated  gross fed funds  borrowing  capacity at $1.319  billion,  compared to
$1.137  billion at  December  31,  2004.  In  addition,  Trustmark  maintains  a
borrowing   relationship  with  the  FHLB,  which  provided  $575.0  million  in
short-term  advances and $205.8 million in long-term  advances at June 30, 2005,
compared  with  $650.0  million in  short-term  advances  and $180.9  million in
long-term  advances at December 31, 2004. 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
$695.0 million  available in unused FHLB advances.  Another  borrowing source is
the  Federal  Reserve  Discount  Window  (Discount  Window).  At June 30,  2005,
Trustmark had approximately  $511.7 million available in collateral  capacity at
the Discount  Window from pledges of auto loans and  securities,  compared  with
$597.5  million  available at December 31, 2004.  In September  2004,  Trustmark
entered into a two-year revolving credit arrangement  enabling  borrowings of up
to $50.0  million,  subject to certain  financial  covenants.  At June 30, 2005,
Trustmark was in compliance  with all financial  covenants and had borrowings on
this line of credit that totaled $11.0 million.

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.

The Board of  Directors  currently  has the  authority to issue up to 20 million
preferred shares with no par value. The ability to issue preferred shares in the
future  will  provide   Trustmark  with  additional   financial  and  management
flexibility for general corporate and acquisition purposes. At June 30, 2005, no
such shares have been issued.

Liquidity  position and strategy are reviewed  regularly by the  Asset/Liability
Committee and  continuously  adjusted in  relationship  to  Trustmark's  overall
strategy.  Management  believes  that  Trustmark  has  sufficient  liquidity and
capital  resources to meet presently known cash flow  requirements  arising from
ongoing business transactions.


CAPITAL RESOURCES

At June 30,  2005,  Trustmark's  shareholders'  equity  was  $744.6  million,  a
decrease of $5.8  million,  or 0.8%,  from its level at December 31, 2004.  This
decrease is primarily related to dividends of $22.8 million,  shares repurchased
at a cost of $32.5 million and a net increase in accumulated other comprehensive
loss of $1.6 million  being offset by net income of $49.0  million for the first
six months of 2005.  Management  will  continue  to hold  sufficient  capital to
provide  for growth  opportunities,  protect the balance  sheet  against  sudden
adverse  market  conditions  and  maintain  an  attractive  return  on equity to
shareholders.

Common Stock Repurchase Program
Trustmark currently has remaining  authorization for the repurchase of up to 1.8
million shares of its common stock,  which will be executed at the discretion of
management,  subject to capital needs and market conditions.  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 19.7 million shares for $432.0 million,
including 287 thousand  shares during the second quarter of 2005 and 1.2 million
shares for the six months ended June 30, 2005.

Dividends
Dividends for the first six months of 2005 were $0.40 per share, increasing 5.3%
when compared with dividends of $0.38 per share in the first six months of 2004.

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, 2005,  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,  2005,  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  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, 2005, earning assets were $7.332 billion,
or 90.5% of total assets, compared with $7.235 billion, or 89.8% of total assets
at December 31, 2004, an increase of $97.2 million, or 1.3%.

Securities
Interest-bearing  investment securities are held to provide a stable alternative
source of interest  income and to  collateralize  public deposits and repurchase
agreements.   Trustmark's  portfolio  of  investment  securities  also  supports
liquidity  and  profitability  strategies  and may be used to  offset  potential
market risks in the various  segments.  The primary  objective of the investment
portfolio is to make an adequate contribution to net interest income. Management
evaluates this  contribution in relation to potential  adverse market value risk
that may impact strategic flexibility,  liquidity or future earnings. During the
fourth  quarter of 2004,  Management  implemented a strategy of exiting  certain
assets and  reducing  balances  of funding  sources  that would bear the highest
costs in a rising interest rate environment. This strategy is illustrated by the
sale of $304 million in  mortgage-related  and U. S. Treasury  securities during
the  fourth  quarter  of 2004,  which  generated  losses  of $4.7  million,  and
continued  during the second quarter of 2005 when Trustmark sold $256 million in
U. S. Government Agency and U. S. Treasury securities,  which incurred losses of
$4.1 million.  The average  maturity of these  securities was 2.14 years with an
average book yield of 2.94%.  Management  believes  projected  funding  costs to
carry these investments to their remaining maturity may have generated a greater
negative  margin impact than the actual losses  incurred at sale.  Proceeds from
sales were used to reduce  balances of higher-cost  funding  sources.  Trustmark
intends  to  maintain  lower  balances  in  investment   securities  and  reduce
dependency on wholesale funding until market conditions  provide more attractive
opportunities. At June 30, 2005, Trustmark's securities portfolio totaled $1.517
billion  compared with $1.717 billion at December 31, 2004, a decrease of $199.8
million, or 11.6%.

The securities  portfolio can serve as a powerful tool that  Management  uses to
control  exposure to interest  rate risk.  Interest rate risk can be adjusted by
altering both the duration of the  portfolio  and the balance of the  portfolio.
Trustmark has maintained a strategy of offsetting  potential  exposure to higher
interest  rates by keeping  both the  duration  and the  balances of  investment
securities at relatively low levels. The estimated duration of the portfolio was
2.46 years at June 30, 2005,  2.47 years at December 31, 2004, and 2.44 years at
June 30, 2004.  While this is a slight  extension of the duration of Trustmark's
securities portfolio,  duration remains near historically low levels. Management
does not expect to extend duration by a material amount during 2005.

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 June 30, 2005, AFS securities
totaled $1.213 billion,  which  represented  79.9% of the securities  portfolio,
compared to $1.580  billion,  or 92.0%,  at December 31, 2004. At June 30, 2005,
unrealized  losses on AFS  securities  of $4.8  million,  net of $1.9 million of
deferred income taxes,  were included in accumulated other  comprehensive  loss,
compared  with  unrealized  losses  of $2.2  million,  net of $841  thousand  in
deferred  income taxes,  at December 31, 2004. At June 30, 2005,  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  June  30,  2005,  HTM  securities  totaled  $304.6  million  and
represented 20.1% of the total portfolio, compared with $136.8 million, or 8.0%,
at the end of 2004.

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,  U.S. Government agencies  obligations and other
AAA rated securities.

Loans and Allowance for Loan Losses
Loans,  including  loans held for sale,  represented  79.0% of earning assets at
June 30, 2005, compared with 75.1% at December 31, 2004. At June 30, 2005, loans
totaled  $5.790  billion,  a 6.6% increase  from its level of $5.431  billion at
December  31,  2004,  due in part to growth in  Trustmark's  Florida Gulf Coast,
Mortgage Banking, Commercial Real Estate and Indirect Auto portfolios.

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, 2005 and December 31, 2004, are shown in the accompanying table.

Total  nonperforming  assets increased $8.8 million,  or 32.2%, during the first
six  months  of  2005.  The  increase  from  December  31,  2004,  is  primarily
attributable to a single  commercial credit of approximately  $14.9 million,  of
which $13.6 million was placed on  nonaccrual  during the first quarter of 2005.
The  allowance  coverage of  nonperforming  loans was 201.63% at June 30,  2005.
Loans held for sale past due 90 days or more  represents  $6.6  million in loans
serviced by Trustmark and fully guaranteed by the Government National Mortgage
Association that are eligible for repurchase.

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

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

At June 30, 2005, the allowance for loan losses was $65.9 million  compared with
$64.8  million at December 31, 2004.  The allowance  represented  1.17% of total
loans  outstanding at June 30, 2005,  compared to 1.21% at December 31, 2004. As
of June 30,  2005,  Management  believes  that  the  allowance  for loan  losses
provides adequate protection in regards to charge-off experience and the current
level of nonperforming assets.

Loans  identified  as losses by  Management,  internal  loan review  and/or bank
examiners  are  charged-off  against the  allowance,  while  consumer  loans are
charged-off based on regulatory requirements.  Net charge-offs for the first six
months of 2005 totaled $3.1 million compared to $2.9 million for the same period
of 2004. The continued  stability in net charge-offs is a result of realignments
of specific underwriting  standards and changes to risk management analysis over
the past 24 months.

Other Earning Assets
Federal funds sold and securities purchased under reverse repurchase  agreements
were $24.0  million at June 30, 2005, a decrease of $62.2  million when compared
with  December  31,  2004.  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 CDs. Total
deposits were $5.521  billion at June 30, 2005,  compared with $5.450 billion at
December 31, 2004, an increase of $70.6  million,  or 1.3%.  Noninterest-bearing
deposits  have  decreased  $105.3  million  during the first six months of 2005,
while  interest-bearing  deposits have increased  $175.9 million during the same
time period. At June 30, 2005,  brokered CDs totaled $189.2 million,  a decrease
of $34.5 million when compared to December 31, 2004.  Trustmark will continue to
utilize a brokered CD program to provide additional deposit funding.  Additional
growth in  interest-bearing  deposits may be attributed  to uncertain  financial
market conditions, which have led to more growth in traditional deposit products
such  as   interest-bearing   demand  deposits.   Management  has  refocused  on
initiatives to expand deposits in our market area as a key to providing low cost
funding for loan growth.

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 $1.554 billion at June 30, 2005, a decrease of $43.7 million,
compared  with $1.598  billion at December 31,  2004.  Long-term  FHLB  advances
totaled  $205.8  million at June 30,  2005,  an increase of $24.9  million  from
December 31, 2004. On a  consolidated  basis,  total  borrowings  have decreased
$18.7  million  when  compared to  December  31,  2004,  as  Trustmark  utilized
liquidity  from the sale of  securities  to  reduce  Trustmark's  dependency  on
wholesale funding products.

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,  with 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 recent years 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 June 30,  2005 and 2004,  Trustmark  had
commitments to extend credit of $1.434 billion and $1.240 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 June 30, 2005
and  2004,  Trustmark's  maximum  exposure  to  credit  loss  in  the  event  of
nonperformance  by the other party for letters of credit was $114.9  million and
$92.8 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 +/- two 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 two 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 June 30,
2005,  it is  estimated  that net  interest  income  may  decrease  0.58%,  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  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 response 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 1.87%.  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  2005.  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. 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 June 30, 2005,  reflected an asset gap of $50 million compared with
a  liability  gap of $189  million  at March 31,  2005.  One-year  gap  analysis
projected at June 30, 2005,  reflected a liability gap of $151 million  compared
with a liability  gap of $571 million at March 31,  2005.  The  three-month  and
one-year gap positions were primarily impacted during the second quarter of 2005
by  increases  in  variable  rate loans,  as well as an  increase in  prepayment
projections on mortgage loans and mortgage  related  securities as a result of a
flattening yield curve. In addition,  the sale of certain investment  securities
reduced  reliance on overnight and other  short-term  wholesale  funding such as
federal funds.  Of the primary asset groups,  Trustmark  expects  maturities and
repricing  of  approximately  $3.365  billion  in loans and  $401.7  million  in
securities during the next twelve months.  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.


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 fair value of these derivatives was
negative $787 thousand at June 30, 2005.

Trustmark continued a risk controlling strategy utilizing caps and floors, which
may be further  implemented  over time.  As of June 30, 2005,  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
June 30, 2005, the fair value of these contracts was $25 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 fair value of these interest rate swaps at
June 30, 2005 was negative $940 thousand.

RECENT PRONOUNCEMENTS

In May 2005,  the Financial  Accounting  Standards  Board (FASB) issued SFAS No.
154,  "Accounting  Changes and Error Corrections." SFAS No. 154 is a replacement
of Accounting  Principles Board Opinion (APB) No. 20,  "Accounting  Changes" and
FASB  Statement  No. 3,  "Reporting  Accounting  Changes  in  Interim  Financial
Statements."  SFAS No.  154  establishes,  unless  impracticable,  retrospective
application  as the  required  method  for  reporting  a  change  in  accounting
principle  in the absence of explicit  transition  requirements  specific to the
newly adopted accounting principle.  This statement applies to voluntary changes
in  accounting   principle  as  well  as  changes   required  by  an  accounting
pronouncement that provide no specific transition provisions.  This statement is
effective for accounting  changes and corrections of errors made in fiscal years
beginning  after  December  15,  2005.  The  effects of this  statement  are not
expected  to have a material  impact on  Trustmark's  statement  of  position or
results of operations.

In December  2004,  the FASB issued a revision of SFAS No. 123 (SFAS No.  123r),
"Share-Based  Payment." This  Statement  revises SFAS No. 123,  "Accounting  for
Stock-Based  Compensation,"  and supersedes APB Opinion No. 25,  "Accounting for
Stock  Issued  to  Employees."  SFAS  No.  123r  establishes  standards  for the
accounting for transactions in which a company exchanges equity  instruments for
goods or  services.  This  statement  requires  companies to measure the cost of
employee services received in exchange for an award of equity  instruments based
on the grant-date  fair value of the award.  As of the required  effective date,
public companies using the fair-value-based method for recognition or disclosure
under  SFAS No.  123,  will  apply this  statement  using a modified  version of
prospective  application.  Trustmark  adopted  the  provisions  of SFAS No.  123
