                      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 generally accepted  accounting  principles
for  interim  financial  information  and with the  instructions  to Form  10-Q.
Accordingly,  they do not include all of the information and footnotes  required
by generally accepted accounting  principles for complete financial  statements.
In the opinion of Management,  all adjustments  (consisting of normal  recurring
accruals)  considered  necessary for the fair presentation of these consolidated
financial  statements  have been included.  The notes included  herein should be
read in  conjunction  with the notes to the  consolidated  financial  statements
included in Trustmark Corporation's (Trustmark) 2000 annual report on Form 10-K.
        The consolidated financial statements include the accounts of Trustmark,
its wholly-owned  subsidiary,  Trustmark National Bank (the Bank) and the Bank's
wholly-owned subsidiaries.  All intercompany accounts and transactions have been
eliminated in consolidation.  Certain  reclassifications have been made to prior
period amounts to conform to the current period presentation.

NOTE 2 - BUSINESS COMBINATIONS
         On April 6, 2001,  Trustmark  completed its merger with Barret Bancorp,
Inc.  (Barret)  in  Barretville,  Tennessee.  Barret,  which had  assets of $503
million,  was the holding company for the former Peoples Bank in Barretville and
Somerville  Bank and  Trust  in  Somerville,  Tennessee.  This  transaction  was
accounted for as a purchase business combination.

NOTE 3 - LOANS
        The following  table  summarizes  the activity in the allowance for loan
losses for the three month periods ended March 31, ($ in thousands):

                                                       2001            2000
                                                     -------         -------
        Balance at beginning of year                 $65,850         $65,850
        Provision charged to expense                   2,400           2,118
        Loans charged off                            (4,438)         (3,771)
        Recoveries                                     1,898           1,653
                                                     -------         -------
        Balance at end of period                     $65,710         $65,850
                                                     =======         =======

         At March 31, 2001 and 2000,  the carrying  amounts of nonaccrual  loans
were $19.0 million and $17.7 million, respectively. Included in these nonaccrual
loans at March 31, 2001 and 2000,  are loans that are  considered to be impaired
and totaled $15.3 million and $13.7 million, respectively. As a result of direct
write-downs,  the specific  allowance  related to these  impaired  loans was not
material.  The  average  carrying  amounts of  impaired  loans  during the first
quarter of 2001 and 2000 were $14.6 million and $13.2 million,  respectively. No
material  amounts of  interest  income  were  recognized  on  impaired  loans or
nonaccrual loans for the first quarter of 2001 or 2000.

NOTE 4 - CONTINGENCIES
        Trustmark and its  subsidiaries are parties to lawsuits and other claims
that arise in the  ordinary  course of  business;  some of the  lawsuits  assert
claims  related to the lending,  collection,  servicing,  investment,  trust and
other business  activities;  and some of the lawsuits allege  substantial claims
for damages. The cases are being vigorously contested.  In the regular course of
business,  Management evaluates estimated losses or costs related to litigation,
and provision is made for anticipated losses whenever  Management  believes that
such losses are probable and can be reasonably  estimated.  At the present time,
Management  believes,  based on the  advice  of legal  counsel,  that the  final
resolution  of pending  legal  proceedings  will not have a  material  impact on
Trustmark's consolidated financial position or results of operations.



NOTE 5 - 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 stock  options  outstanding  during the
period.  The following table reflects  weighted average shares used to calculate
Basic and Diluted EPS for the periods presented:

                                                     Three Months Ended

         Diluted                                  64,515,627    69,785,096

NOTE 6 - STATEMENTS OF CASH FLOWS
        Trustmark  paid  income  taxes  approximating  $213  thousand  and  $234
thousand  during the three months  ended March 31, 2001 and 2000,  respectively.
Interest paid on deposit  liabilities and other  borrowings  approximated  $65.1
million in the first  quarter of 2001 and $57.3  million in the first quarter of
2000. For the three months ended March 31, 2001 and 2000, noncash transfers from
loans  to  foreclosed   properties   were  $395  thousand  and  $758   thousand,
respectively.

NOTE 7 - RECENT PRONOUNCEMENTS
        In September  2000,  the  Financial  Accounting  Standards  Board (FASB)
issued  Statement  of  Accounting  Standards  (SFAS)  No.  140  "Accounting  for
Transfers and Servicing of Financial Assets and Extinquishments of Liabilities."
SFAS No. 140 provides  accounting  and reporting  standadards  for transfers and
servicing  of  financial  assets  and  extinguishments  of  liabilities  and  is
effective  for  events  occurring  after  March 31,  2001.  Management  does not
anticipate  the  effect of this  pronouncement  will have a  material  impact on
Trustmark's consolidated financial statements.

NOTE 8 - SEGMENT INFORMATION
        Trustmark has three  reportable  segments:  Retail  Banking,  Commercial
Banking  and  Financial  Services.  Retail  Banking  delivers  a full  range  of

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS
         The  following   provides  a  narrative   discussion  and  analysis  of
significant changes in 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.
         The  Private  Securities  Litigation  Reform  Act  evidences  Congress'
determination  that the disclosure of  forward-looking  information is desirable
for  investors  and  encourages  such  disclosure by providing a safe harbor for
forward-looking  statements by Management.  Management's Discussion and Analysis
of  Financial  Condition  and  Results of  Operations  contains  forward-looking
statements  with respect to the adequacy of the allowance  for loan losses;  the
effect of legal  proceedings  on  Trustmark's  financial  condition,  results of
operations and liquidity;  and market risk disclosures.  Although  Management of
Trustmark  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.  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.

FINANCIAL HIGHLIGHTS
         For the first quarter of 2001,  Trustmark's  basic and diluted earnings
per share were  $0.40,  compared  with $0.37 for the first  quarter of 2000,  an
increase of 8.1%. Net income totaled $25.9 million in the first quarter of 2001,
compared with $25.7 million for the same period in 2000. Trustmark's performance
for the quarter ended March 31, 2001,  resulted in a return on average assets of
1.53%, a return on average  equity of 16.79% and an efficiency  ratio of 54.32%.
These  compared with 2000 ratios of 1.52% for return on average  assets,  15.84%
for return on average equity and 53.06% for the efficiency  ratio.  At March 31,
2001,  Trustmark  reported  total loans of $4.1  billion,  total  assets of $6.8
billion,  total  deposits  of $4.1  billion and  shareholders'  equity of $643.5
billion.  At March 31, 2000,  Trustmark  reported  total loans of $4.1  billion,
total assets of $6.7 billion,  total deposits of $3.9 billion and  shareholders'
equity of $644 million.

RESULTS OF OPERATIONS

NET INTEREST INCOME
        Net interest  income  (NII) 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  NII 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 fully taxable  equivalent  (FTE) yield on
tax-exempt income has been computed based on a 35% federal marginal tax rate for
the periods  shown.  The  following  table  summarizes  Trustmark's  NIM for the
periods shown:
                                                  Quarter Ended

                                                 ======    =====

        For the quarter  ended March 31, 2001,  NII decreased  $1.5 million,  or
2.4%, compared with the same period in 2000. Average interest-earning assets for
the first three months of 2001 were $6.322  billion,  compared to $6.227 billion
for the first three  months of 2000,  an  increase  of $95 million or 1.5%.  The
average  interest-earning  asset growth is  attributable  to a 1.0%  increase in
average  loans and a 4.0%  increase in average  securities,  when  comparing the
first three months of 2001 to the same period in 2000. This combination resulted
in growth in interest income of $3.8 million,  or 3.2%, when comparing the first
three months of 2001 to the same period in 2000. The growth in interest  income,
however,  was  offset by an  increase  in funding  costs  from  interest-bearing
liabilities.   While  average  interest-bearing  deposits  increased  6.7%  when



comparing  the first three months of 2001 with the same period in 2000,  average
short-term borrowings and FHLB advances decreased 5.0%. The increase in the base
of  core  deposits  allowed  Trustmark  to  reduce  reliance  on  higher  priced
short-term borrowings.  This  combination  resulted  in  an increase in interest
expense totaling $5.2 million,  or 9.0% when comparing the first quarter of 2001
to the same time period in 2000.
        The capital  management plan also  contributed to the decrease in NII as
Trustmark  utilized  available  funds  to  repurchase  common  stock.  Trustmark
continues to be heavily involved in this program during 2001, as demonstrated by
the repurchase of $8.4 million in common stock.

PROVISION FOR LOAN LOSSES
         Trustmark's  provision for loan losses  totaled $2.4 million during the
first three months of 2001, compared to $2.1 million in the same period in 2000.
The  provision to average loans was 0.24% for the first quarter of 2001 compared
with 0.21% for the same period in 2000.  The provision for loan losses  reflects
Management's  assessment  of the  adequacy of the  allowance  for loan losses to
absorb inherent charge-offs in the loan portfolio. The provision for each period
is dependent upon many factors including loan growth,  net charge-offs,  changes
in the composition of the loan portfolio, delinquencies, Management's assessment
of loan portfolio quality, the value of collateral and general economic factors.
Trustmark's  provision  for loan  losses to average  loans  continues  to remain
favorable because of asset quality and compares favorably with its peer banks.

NONINTEREST INCOME
        Noninterest  income consists of revenues generated from a broad range of
banking,  insurance and  investment  products and services.  For the first three
months  of  2001,  noninterest  income  increased  by $282  thousand,  or  0.9%.
Excluding the securities  gains which occurred  during the first quarter of 2000
as a result of the  adoption of  Statement  of  Financial  Accounting  Standards
(SFAS) No. 133, "Accounting for Derivative  Instruments and Hedging Activities",
noninterest  income increased $4.9 million,  or 18.0%,  when comparing the first
quarter of 2001 to the same period in 2000.
        Service  charges for deposit  products and  services  continue to be the
single largest component of noninterest  income.  Income from service charges on
deposit  accounts  increased $541 thousand,  or 5.5% during the first quarter of
2001,  when compared to the first quarter of 2000.  Revised fee  structures  for
certain  deposit  services,  the overall growth in fee-based  deposit  accounts,
transaction  volume and an  intensified  effort to collect fees  resulted in the
increase.
        The second  largest  component of  noninterest  income is other  account
charges, fees and commissions.  In the first three months of 2001, a decrease in
these areas totaled $272 thousand,  or 3.0%, when compared to the same period in
2000,  primarily  from a reduction  in insurance  commissions.  Credit card fees
increased  11.8% in the first three months of 2001,  compared to the same period
in 2000 and reflect an increase in interchange income,  merchants' discounts and
volume of accounts  resulting from management's  efforts to increase income from
these services.
        Mortgage servicing fees grew $419 thousand or 11.4% in the first quarter
of 2001, when compared to the same period in 2000.  Reductions in interest rates
have resulted in an increase in volume of mortgages serviced. Trustmark serviced
$3.9 billion in mortgage loans at March 31, 2001.
        Trust service  income  increased  slightly in the first quarter of 2001,
compared to the same period in 2000.  Current market conditions have contributed
to a decline in corporate  trust fees and  advisory  fees during the first three
months  of  2001,  compared  to the same  period  in 2000.  At March  31,  2001,
Trustmark,  which  continues  to be  one  of  the  largest  providers  of  asset
management  services in Mississippi,  held assets under  administration  of $6.5
billion.
        Other  income  totaled  $5.4  million  for the  first  quarter  of 2001,
compared to $1.2 million during the same period in 2000.  The primary  component
of this increase is a $3.9 million gain  resulting from the sale of $192 million
in mortgage loans with significant prepayment risk.
        During the first quarter of 2001, no gains on security transactions were
recognized.  During the first  quarter of 2000,  securities  gains  totaled $4.6
million,  which were realized from sales of AFS equity  securities and were used
to offset  the effect of  adopting  SFAS No.  133,  "Accounting  for  Derivative
Instruments and Hedging Activities."

NONINTEREST EXPENSES
        Total noninterest expenses increased $1.1 million, or 2.2%, in the first
quarter of 2001, compared to the same period in 2000. The control of noninterest
expenses is a management  priority.  The primary measure of the effectiveness of
noninterest  expense  control is the  efficiency  ratio,  which is calculated by
dividing total noninterest  expenses by tax-equivalent  net interest income plus



noninterest  income.  The  efficiency  ratio measures the percentage of revenues
that are  absorbed  by costs  of  production.  For the  first  quarter  of 2001,
Trustmark's efficiency ratio, excluding nonrecurring items, was 54.32%, compared
to 53.06% for the same period in 2000.
        Salaries and employee  benefits  were $26.2 million in the first quarter
of 2001,  compared to $25.4  million in the same period in 2000.  The  increase,
which is the largest in the  noninterest  expense  category,  represents  normal
annual merit increases  offset by a reduction in full time equivalent  employees
of 26. All other categories in noninterest  expenses remained well controlled as
evidenced  by only  slight  increases  during the first  quarter  of 2001,  when
compared to the same period in 2000. Management will continue to closely monitor
the  level of  noninterest  expenses  as part of its  strategic  plan  effort to
improve the profitability of Trustmark.

INCOME TAXES
         For the quarter ended March 31, 2001,  Trustmark's  combined  effective
tax rate was 35.1% compared with 33.7% for the same period in 2000. The increase
in Trustmark's effective tax rate for 2001 is due primarily to the receipt of
non-taxable life insurance proceeds in the first quarter of 2000.

SHAREHOLDERS' EQUITY
        In order to enhance  shareholder  value,  Trustmark  initiated a capital
management plan during 1998. This plan included a number of initiatives designed
to improve earnings per share and return on equity,  two of the most significant
factors  impacting   shareholder  value.  Two  of  these  initiatives  were  the
implementation  of a common  stock  repurchase  program  and the  evaluation  of
Trustmark's  dividend  payout ratio.  Shareholders'  equity  increased to $643.5
million at March 31, 2001 from $629.6  million at December 31, 2000. As a result
of these  initiatives,  Trustmark's  return on average  equity has  increased to
16.79% at March 31, 2001 from 15.58% at December 31, 2000.  The  utilization  of
this  capital  management  plan has allowed  Trustmark  to increase  shareholder
value, while maintaining sufficient regulatory capital levels.

COMMON STOCK REPURCHASE PROGRAM
        In November 1998,  Trustmark  implemented the first phase of its capital
management  plan by  authorizing  the  repurchase of up to 7.5%, or 5.46 million
shares of common stock. This program was completed in the third quarter of 2000,
with purchases  totaling  $112.4  million.  During the third quarter of 2000, an
additional  plan was authorized by Trustmark's  Board of Directors to repurchase
an additional  5.0%, or  approximately  3.4 million  shares of common stock.  At
March 31, 2001, Trustmark had repurchased $9.9 million in common stock under the
latest plan,  $8.4 million  which were  repurchased  during the first quarter of
2001. The new plan  continues to be subject to market  conditions and management
discretion.  Since  implementation  of  these  plans,  Trustmark  has  purchased
approximately 9.3 million shares of common stock totaling over $181 million.

DIVIDENDS
        An increased  dividend  payout ratio is another means by which Trustmark
has enhanced shareholder value.  Trustmark's dividend payout ratio was 33.8% for
the quarters  ended March 31, 2001 and 2000.  Dividends for the first quarter of
2001 were $0.135 per share,  an increase of 8.0% when compared with dividends of
$0.125 per share the same period in 2000.

REGULATORY CAPITAL
        Trustmark  and  Trustmark  National  Bank  (Bank) 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 the Bank.
        Management  believes,  as of March 31, 2001, that Trustmark and the Bank
meet all capital adequacy  requirements to which they are subject.  At March 31,
2001,  the most recent  notification  from the Office of the  Comptroller of the
Currency (OCC)  categorized the Bank as well  capitalized.  To be categorized in
this manner, the Bank must maintain minimum total risk-based,  Tier 1 risk-based
and Tier 1 leverage ratios  (defined in applicable  regulations) as set forth in
the  table  below.  There are no  significant  conditions  or  events  that have
occurred since the OCC's notification that Management believes have affected the
Bank's present classification.



        Actual and minimum  regulatory  capital  amounts and ratios at March 31,
2001, for Trustmark and the Bank are as follows ($ in thousands):

 EARNING ASSETS
        Earning assets are comprised of securities,  loans,  federal funds sold,
securities  purchased under resale agreements and trading account assets,  which
are the primary revenue streams for Trustmark. At March 31, 2001, earning assets
were $6.261 billion, or 91.75% of total assets, compared with $6.318 billion, or
91.74% of total assets at December 31,  2000,  a decrease of $56.9  million,  or
0.9%. This decrease is  the direct result of the previously  discussed  strategy
Trustmark  executed  during the first  quarter  of 2001 to sell $192  million in
mortgage loans with significant prepayment risk.

SECURITIES
        The securities portfolio is utilized to provide Trustmark with a quality
investment  alternative,  a  stable  source  of  interest  income,  as well  as,
collateral for pledges on public deposits and securities  sold under  agreements
to  repurchase.  At March 31, 2001,  Trustmark's  securities  portfolio  totaled
$2.206 billion,  compared to $2.125 billion at December 31, 2000, an increase of
$81.4  million,  or 3.8%.  The  increase is the result of Trustmark  reinvesting
the  proceeds  from  the  mortgage  loan  sale,  discussed  previously,  in  AFS
securities in order to reposition the balance sheet.
        AFS securities are carried at their estimated fair value with unrealized
gains or losses  recognized,  net of taxes, in accumulated  other  comprehensive
income,  a separate  component of shareholders'  equity.  At March 31, 2001, AFS
securities  totaled $1.250 billion,  which  represented  56.6% of the securities
portfolio, compared to $1.120 million or 52.7% at December 31, 2000.
        HTM  securities  are  carried  at  amortized  cost and  represent  those
securities that Trustmark both positively intends and has the ability to hold to
maturity. At March 31, 2001, HTM securities totaled $957 million and represented
43.4% of the total portfolio,  compared with $1.005 billion or 47.3% at December
31, 2000.
     Management  continues to stress asset quality as one of the strategic goals
of the securities portfolio, which is evidenced by the investment of over 85% of
the portfolio in U. S. Treasury and U. S.  Government  agency  obligations.  The
REMIC  and CMO  issues  held in the  securities  portfolio  are  entirely  U. S.
Government  agency issues.  In order to avoid  excessive  yield  volatility from
unexpected  prepayments,  Trustmark's normal practice is to purchase  investment
securities at or near par value to reduce the risk of premium write-offs.

LOANS
        Loans,  the largest  group of earning  assets,  totaled 64.7% of earning
assets at March 31, 2001, compared with 65.6% at December 31, 2000. At March 31,
2001,  loans totaled $4.053 billion compared to $4.144 billion at year-end 2001,
a decrease of $90.8 million, or 2.2%. As previously discussed,  during the first
quarter of 2001,  Trustmark executed a strategy to sell $192 million in mortgage
loans with significant  prepayment  risk.  Excluding this sale, loans would have
increased  $101.2  million  or  2.4%.  Loan  growth  has  slowed,   but  remains
broad-based, led by business banking and mortgage refinance volume.
         Trustmark's  lending policies have produced  consistently  strong asset
quality.  One measure of asset quality in the financial services industry is the



level of nonperforming  assets.  Trustmark's  nonperforming  assets at March 31,
2001 and December 31, 2000, are shown in the following table ($ in thousands):

                                              Mar. 31,     Dec. 31,
  Nonperforming Assets                          2001         2000
  --------------------                        --------     --------
  Nonaccrual and restructured loans           $ 18,951     $ 15,958
  Other real estate (ORE)                        2,355        2,280
                                              --------     --------
       Total nonperforming assets             $ 21,306      $18,238
                                              ========     ========
  Accruing loans past due 90 days or more       $2,445       $2,494
                                              ========     ========
  Nonperforming assets/total loans and ORE       0.53%        0.44%
                                              ========     ========

        While the volume of nonperforming  assets at March 31, 2001, reflects an
increase from year-end 2000, as indicated in the preceding  table,  the level of
nonperforming  assets  continues  to compare  favorably  to those of peer banks.
Management is not aware of any additional  credits,  other than those identified
above, where serious doubts as to the repayment of principal and interest exist.
        At March 31,  2001,  the  allowance  for loan losses was $65.7  million,
representing  1.62% of total loans  outstanding,  compared to $65.9  million and
1.59% at December 31, 2000.  The  allowance  for loan losses is  maintained at a
level that  Management and the Board of Directors  believe is adequate to absorb
estimated probable losses within the loan portfolio, including losses associated
with off-balance sheet credit instruments such as letters of credit and unfunded
lines of credit. A formal analysis is prepared monthly to assess the risk in the
loan  portfolio  and to determine the adequacy of the allowance for loan losses.
Specifically,  the analysis  considers  any  identified  impairment,  as well as
historical loss experience in relation to volume and types of loans,  volume and
trends in delinquencies and nonaccruals,  national and local economic conditions
and other pertinent information. This analysis is presented to the Credit Policy
Committee with subsequent review and approval by the Board of Directors.
        Net charge-offs were $2.5 million or 0.25% of average loans at March 31,
2001,  compared  with $2.1 million or 0.21% of average  loans at March 31, 2000.
Trustmark's  level of net  charge-offs  to average  loans  continues  to compare
favorably to those of peer banks.

OTHER EARNING ASSETS
        Federal funds sold and  securities  purchased  under reverse  repurchase
agreements were $1.2 million at March 31, 2001, a decrease of $46.6 million when
compared with year-end 2000.  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.  Total deposits were
$4.107  billion at March 31,  2001 and  averaged  $4.081  billion  for the first
quarter of 2001. This compares with  quarter-end and quarterly  average deposits
for  December  31,  2000 of $4.058  billion  and $3.961  billion,  respectively.
Interest-bearing  deposits  increased  3.4% from  December 31, 2000 to March 31,
2001. During this period,  interest-bearing  demand deposits increased 14.7% and
large  certificates of deposits rose 5.4%.  Non-interest  bearing  deposits grew
1.8% during the same period.  Deposit mix remains  favorable  with  non-interest
deposits  representing 22% of total deposits.  Trustmark continues to search for
reasonably priced funding alternatives by evaluating new deposit products.
         Short-term  borrowings  consist of federal funds purchased,  securities
sold under repurchase agreements,  FHLB borrowings and the treasury tax and loan
note option account.  Short-term  borrowings totaled $1.558 billion at March 31,
2001, a decrease of $330.4 million, compared with $1.888 billion at December 31,
2000.  This  difference is primarily  related to the  utilization of a long-term
borrowings category,  which totaled $450 million at March 31, 2001 and consisted
entirely of FHLB advances.  Significant  funding remains  available through FHLB
borrowings.

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  effectively
invest capital 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 modeling system that provides information used to
evaluate  exposure to interest rate risk,  project  earnings and manage  balance
sheet growth.  This modeling system utilizes the following scenarios in order to
give  Management a method of evaluating  Trustmark's  interest  rate,  basis and
prepayment risk under different conditions:

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

         A static gap  analysis  is a tool used  mainly for  interest  rate risk
measurement,   which   highlights   significant   short-term   repricing  volume
mismatches.  Management's assumptions related to the prepayment of certain loans
and securities as well as the maturity for rate sensitive assets and liabilities
are utilized for sensitivity static gap analysis. At March 31, 2001, the balance
sheet was  liability-sensitive to interest rate movements with $902 million more
liabilities  than  assets  scheduled  to reprice  within  three  months and $921
million  scheduled to reprice  within one year.  At March 31, 2001,  Trustmark's
static gap  analysis  indicates  that net  interest  income  would  benefit from
additional decreases in market interest rates.
        Trustmark   uses   derivatives  to  hedge  interest  rate  exposures  by
mitigating  the interest rate risk of mortgage  loans held for sale and mortgage
loans  in  process.   Trustmark  regularly  enters  into  derivative   financial
instruments  in  the  form  of  forward   contracts,   as  part  of  its  normal
asset/liability  management strategies.  Forward contracts, a type of derivative
financial  instrument,  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.
         During the second half of 2000,  Trustmark  began a strategy to utilize
caps and floors,  which will be  implemented  over time. 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 have not been
designated  as hedging  instruments,  are options  that are 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.

LIQUIDITY
        Trustmark's  goal is to  maintain  an  adequate  liquidity  position  to
satisfy the cash flow requirements of depositors and borrowers while meeting the
cash flow  needs  which  Trustmark  requires  for  growth.  The  Asset/Liability
Committee  establishes  guidelines  by which the current  liquidity  position is
monitored to ensure adequate funding capacity.  This is accomplished through the
active management of both the asset and liability sides of the balance sheet and
by maintaining  accessibility  to local,  regional and national funding sources.
The ability to maintain  consistent  earnings and adequate capital also enhances
Trustmark's liquidity.

BUSINESS COMBINATIONS
         On April 6, 2001,  Trustmark  completed its merger with Barret Bancorp,
Inc.  (Barret)  in  Barretville,  Tennessee.  Barret,  which had  assets of $503
million,  was the holding company for the former Peoples Bank in Barretville and
Somerville  Bank and  Trust  in  Somerville,  Tennessee.  This  transaction  was
accounted for as a purchase business combination.
