                                     PART I

ITEM 1. BUSINESS

GENERAL

     Trustmark Corporation (the Corporation) is a one-bank holding company which
was  incorporated  under the Mississippi  Business  Corporation Act on August 5,
1968, and commenced doing business in November 1968. The  Corporation's  primary
business activities are conducted through its wholly-owned subsidiary, Trustmark
National  Bank (the  Bank) and the  Bank's  wholly-owned  subsidiary,  Trustmark
Financial Services,  Inc. (TFSI). The Bank accounts for substantially all of the
assets and revenues of the Corporation. Chartered by the State of Mississippi in
1889, the Bank is headquartered in Jackson,  Mississippi and is the largest bank
in the state. The Corporation also owns all of the stock of F.S. Corporation and
First  Building  Corporation,   both  nonbank  Mississippi  corporations.   F.S.
Corporation  and First Building  Corporation  are primarily  dormant and are not
considered significant subsidiaries.
     The Bank offers a variety of deposit, investment and credit products to its
customers through strategic business units serving 185 locations in the State of
Mississippi.  During 1997,  the Bank's  existing  strategic  business units were
realigned  into  new  groups  which  included  the  Retail  Banking  Group,  the
Commercial Banking Group and the Financial Services Group.
     The  Retail   Banking  Group  includes  the  Community   Banking   Network,
Residential  Mortgage,  Retail and Small Business  Services.  Both the Community
Bank Network,  which  manages 19 community  banks with over 100 branches and the
Retail Unit,  which  administers  Card Services,  Indirect Lending and all Metro
Jackson branches,  provide traditional banking products primarily to individuals
and small  businesses.  In order to provide  customers  with  services  that are
convenient and meet their demanding schedules, both Community Banking and Retail
branches  have been opened  inside  Wal-Mart  stores,  Kroger  supermarkets  and
Albertson's supermarkets. In order to allow customers to do their banking around
the clock from their homes or  offices,  the Bank now offers  TrustTouch  pc, an
on-line banking service.  Customers may also obtain information about the Bank's
services via the Internet by accessing its web site (www.trustmark.com). Through
the Retail Unit, the Bank's Card Services offer MasterCard,  VISA, VISA Gold and
VISA  Business  credit  card  services to  consumers  and  merchants  throughout
Mississippi.  In addition,  the Bank now has more than  100,000  debits cards in
use.  The  Indirect   Lending  area  is  affiliated  with  over  100  automobile
dealerships  across  the region  and has  enabled  the Bank to become the second
largest  financier of automobiles in Mississippi and the largest among financial
institutions.  A natural  extension of Retail Services,  the Bank's  Residential
Mortgage   Unit  offers   first  time  and  repeat  home   borrowers   financing
opportunities at several convenient locations throughout the state.



     The Commercial  Banking Group  provides  loans,  deposit  services and cash
management  to  businesses  and banks  statewide.  The  Deposit/Cash  Management
department  offers new  technology  and services for  businesses to monitor cash
flows through the utilization of TrustNet computer banking,  automated  clearing
services  which  facilitates  electronic  bill  payment  and  direct  deposit of
employee  pay and the Bank's  Mutual  Fund Sweep  account.  The Bank offers real
estate loans  targeting  residential  construction  builders and  developers  in
addition to commercial  real estate  construction  and financing.  The Bank also
lends to  moderate  and lower  income  homeowners  in  several  markets  through
Community  Reinvestment Act programs such as the Downpayment  Assistance Program
and Farmers Home Multi-Family  Home Program.  The Bank's  Correspondent  Banking
Department  maintains  relationships with more than 100 independent banks across
the state,  providing  competitively priced cash management services,  financing
and clearing services.
     The  Financial  Services  Group  offers  trust and  investment  services to
individuals,   corporations  and  public  entities.   With  $5.6  billion  under
administration,  the  Bank's  Trust  Department  offers  a full  line  of  asset
management and custodial services.  In early 1997, Trustmark Financial Services,
Inc.  (TFSI),  a subsidiary of the Bank began  offering  full-service  brokerage
services at discount prices. TFSI offers mutual funds,  equities,  corporate and
municipal bonds, and self-directed  Individual  Retirement Accounts.  The Public
Services  Department  specializes  in  serving  the  financial  needs of  public
entities such as state agencies, municipal government and school districts.
     As of March 16, 1998, the Corporation  and the Bank employed  approximately
2,300 full-time equivalent employees.

COMPETITION

     The Bank  competes  with  national and state banks in its service areas for
all types of depository,  credit, investment and trust services. In addition, it
competes  in its  respective  service  areas with other  financial  institutions
including  savings and loan  associations,  personal  loan  companies,  consumer
finance companies,  mortgage companies,  insurance  companies,  brokerage firms,
investment  companies,  credit unions and financial service  operations of major
retailers.  All these  institutions  compete in the areas of interest rates, the
availability  and quality of  services  and  products,  and the pricing of these
services and products.

SUPERVISION AND REGULATION

     The Corporation is a registered bank holding company under the Bank Holding
Company Act of 1956, as amended. As such, the Corporation is required to file an
annual report and such  additional  information as the Board of Governors of the
Federal Reserve System may require.  The Act requires every bank holding company
to obtain the prior approval of the Board of Governors



before it may acquire  substantially all of the assets of any bank, or ownership
or control of any voting shares of any bank, if, after the acquisition, it would
own or control,  directly or  indirectly,  more than five  percent of the voting
shares of the bank. In addition,  a bank holding company is generally prohibited
from engaging in or acquiring direct or indirect control of voting shares of any
company  engaged in nonbanking  activities.  One of the principal  exceptions to
this prohibition is for activities found by the Board of Governors,  by order or
regulation,  to be closely  related to banking or managing or controlling  banks
"as to be a proper  incident  thereto." The Board has by  regulation  determined
that a number of activities are closely related to banking within the meaning of
the Act. In addition,  the  Corporation is subject to regulation by the State of
Mississippi under its laws of incorporation.
     The Bank is subject to various requirements and restrictions by federal and
state  banking  authorities,  including  the  Office of the  Comptroller  of the
Currency  (OCC) and the  Mississippi  Department  of Banking.  Areas  subject to
regulation  include  loans,  reserves,  investments,   issuance  of  securities,
establishment  of branches,  loans to  directors,  executive  officers and their
related interests,  relationships with correspondent banks,  consumer protection
and other  aspects of  operations.  In addition,  national  banks are subject to
legal limitations on the amount of earnings they may pay as dividends.
     The Bank also is insured by, and therefore  subject to, the  regulations of
the Federal Deposit Insurance  Corporation (FDIC). In December 1991, the Federal
Deposit  Insurance  Corporation  Improvement  Act of 1991  (FDICIA) was enacted.
FDICIA substantially revised the depository  institution  regulatory and funding
provisions of the Federal  Deposit  Insurance Act and made  revisions to several
other federal banking  statutes.  Among other things,  FDICIA  requires  banking
regulators to take prompt corrective action whenever  financial  institutions do
not  meet  minimum  capital  requirements.   In  addition,  FDICIA  has  created
restrictions on capital distributions that would leave a depository  institution
undercapitalized.  FDICIA  regulations also include  procedures and interpretive
guidelines that mandate certain audit and reporting  requirements  for financial
institutions. Management is responsible for not only preparing the Corporation's
annual financial  statements,  but also  establishing  and maintaining  adequate
internal controls over financial reporting. In addition,  Management must comply
with certain laws and  regulations  designated by the FDIC as well as assess the
effectiveness  of the controls that have been  established  to comply with these
laws and regulations.

STATISTICAL DISCLOSURES

     The  consolidated  statistical  disclosures  for Trustmark  Corporation and
subsidiaries are contained in the following Tables 1 through 12.
     During  1997,  the  Corporation  completed  two business  combinations.  On
February 28,  1997,  the  Corporation  completed  its merger with First  Corinth
Corporation  (FCC) and its  subsidiary,  National  Bank of  Commerce of Corinth,
Mississippi  (NBC) in a  business  combination  accounted  for as a  pooling  of
interests.  At the merger date, FCC and NBC had  approximatgely  $134 million in
total assets. As a result of this transaction,  the Corporation has restated its
financial  statements to include FCC and NBC as of January 1, 1997. Prior years'
statistical  disclosures  were not  restated  as the  changes  would  have  been
immaterial.  On  September  19,  1997,  Perry  County Bank (PCB) in New Augusta,
Mississippi was merged with the Corporation in a business combination  accounted
for  by the  purchase  method  of  accounting.  At  the  merger  date,  PCB  has
approximately  $43 million in total assets.  PCB's results of operations,  which
are not material,  have been included in the  statistical  disclosures  from the
merger date.

     Nonaccruing  loans have been  included in the  average  loan  balances  and
interest  collected  prior to these loans having been placed on  nonaccrual  has
been included in interest income. Loan fees included in interest associated with
the average loan balances are  immaterial.  Interest income and average yield on
tax-exempt  assets have been calculated on a fully tax equivalent  basis using a
tax rate of 35% for each of the three years presented. Certain reclassifications
have been made to the 1996 and 1995  statements to conform to the 1997 method of
presentation.

     Due to the nature of mortgage related securities,  the actual maturities of
these investments can be substantially  shorter than their contractual maturity.
Management  believes the actual weighted average maturity of the entire mortgage
related portfolio to be approximately 2.33 years.
     As of December 31, 1997 the Corporation  held securities of one issuer with
a carrying value exceeding ten percent of total  stockholders'  equity.  General
obligations  of the State of Mississippi  with a carrying value of  $124,979,000
and an approximate  fair value of  $128,820,000  were held on December 31, 1997.
Included in the aforementioned  State of Mississippi  holdings are bonds with an
aggregate  carrying  value  of  $17,087,000  and an  approximate  fair  value of
$18,827,000  which are known to be  prerefunded or escrowed to maturity by U. S.
Government securities.

     Generally,  a loan is classified as nonaccrual  and the accrual of interest
on such loan is discontinued when a contractual payment of principal or interest
has  become  90  days  past  due  or   Management   has  serious   doubts  about
collectibility  of  principal  or  interest  even  though the loan is  currently
performing.  A  delinquent  loan may remain in an accruing  status if it is well
secured  and in  process  of  collection.  When a loan is placed  in  nonaccrual
status,  unpaid  interest  credited  to income in the current and prior years is
reversed  against  interest  income.  Interest  received on nonaccrual  loans is
applied  against  principal.  Loans are  restored  to  accrual  status  when the
obligation  is  brought   current  or  has  performed  in  accordance  with  the
contractual   terms  for  a  reasonable   period  of  time,   and  the  ultimate
collectibility of all contractual  principal and interest is no longer in doubt.
Interest which would have accrued on nonaccrual and  restructured  loans if they
had been in compliance  with their original  terms is  immaterial.  In addition,
interest  income on these loans that was  included in net income for the periods
presented was immaterial.
     At December 31, 1997  Management  is not aware of any  additional  credits,
other than those identified  above,  where serious doubts as to the repayment of
principal and interest exist. There are no  interest-earning  assets which would
be required to be disclosed  above if those assets were loans.  The  Corporation
had no loan  concentrations  greater  than ten percent of total loans other than
those loan categories shown in Table 5.

     The allowance for loan losses is maintained at a level believed adequate by
Management  to absorb  estimated  possible  loan losses.  Management's  periodic
evaluation of the adequacy of the allowance is based on the  Corporation's  past
loan  loss  experience,  known  and  inherent  risks in the  portfolio,  adverse
situations that may affect the borrower's ability to repay (including the timing
of  future  payments),   the  estimated  value  of  any  underlying  collateral,
composition  of the loan  portfolio,  current  economic  conditions,  and  other
relevant  factors.  This  evaluation  is  inherently  subjective  as it requires
material  estimates  including  the  amounts  and  timing of future  cash  flows
expected to be received on impaired loans that may be susceptible to significant
change.



TABLE 9 - ALLOCATION OF THE ALLOWANCE FOR LOAN LOSSES

     The  following   table  is  a  summary  by   allocation   category  of  the
Corporation's  allowance for loan losses at December 31, 1997. These allocations
were  determined by internal  formulas based upon  Management's  analysis of the
various  types of risk  associated  with the  Corporation's  loan  portfolio.  A
discussion of Management's  methodology for performing the analysis  follows the
table ($ in thousands):


    Allocation for pools of risk-rated loans                           $29,048
    Additional allocation for risk-rated loans                           2,488
    Allocation for selected industries                                   3,592
    General allocation for all other loans                               9,687
    Allocation for available lines of credit and letters of credit       2,560
    Discretionary                                                       16,725
                                                                       -------
      Total                                                            $64,100
                                                                       =======


     The allowance for loan losses is maintained at a level which Management and
the Board of Directors  believe is adequate to absorb estimated  possible losses
inherent  in  the  loan  portfolio,   plus  estimated  losses   associated  with
off-balance  sheet  credit  instruments  such as letters of credit and  unfunded
lines of credit. The adequacy of the allowance is reviewed  quarterly  utilizing
the  criteria  specified  in the  Office of the  Comptroller  of the  Currency's
revised  Banking  Circular 201 as well as  additional  guidance  provided in the
Interagency  Policy Statement.  Loss percentages were uniformly applied to pools
of risk-rated  loans within the commercial  portfolio.  These  percentages  were
determined based on migration analysis,  previously  established floors for each
category and economic  factors.  In addition,  relationships of $500,000 or more
which were risk-rated  Other Loans  Especially  Mentioned or Substandard and all
which were risk-rated Doubtful were reviewed by the Corporation's Internal Asset
Review staff to determine if the standard  percentages appeared to be sufficient
to cover  potential loss on each line. In the event that the  percentages on any
particular lines were determined to be insufficient, additional allocations were
made based upon recommendations of lending and asset review personnel.
     Industry allocations were made based on concentrations of credit within the
portfolio  as well as  arbitrary  designation  of certain  other  industries  by
Management.
     The general allocation is included in the allowance to cover potential loan
losses within  portions of the loan  portfolio  not addressed in the  preceeding
allocations.  The  types  of  loans  included  in the  general  allocation  were
residential  mortgage loans,  direct and indirect  consumer  loans,  credit card
loans and  overdrafts.  The  actual  allocation  amount  was based upon the more
conservative  estimate of loss experience  within these categories  during 1997,
the  historical   5-year  moving  average  for  each  category,   or  previously
established floors.
     The amount  included in the  allocation  for lines of credit and letters of
credit  consists of a  percentage  of the unused  portion of those lines and the
amount outstanding in letters of credit.  Arbitrary percentages,  which were the
same as those applied to the funded  portions of the  commercial and retail loan
portfolios,  were  applied to cover any  potential  losses in these  off-balance
sheet categories.
     The remaining  $16,725,000 is discretionary  and serves as added protection
in the event that any of the above  specific  components  are  determined  to be
inadequate or for issues that cannot or have not been measured on a quantitative
basis over a prolonged period of time.
     Because  of the  present  stability  shown  by the  Corporation's  level of
nonperforming assets, Management does not anticipate that the percentage of 1998
net charge-offs to total loans to be significantly  higher than that experienced
in 1997.  However,  because of the  imprecision  inherent in most  estimates  of
expected credit losses,  Management will continue to take a prudent  approach in
the evaluation of the allowance for loan losses.

     Disclosure  of other  short term  borrowings  is not  required  because the
average balance for 1997 was less than 30% of stockholders' equity at the end of
1997.



ITEM 2. PROPERTIES

     The Corporation's  principal  offices are housed in a 14-floor  combination
office and bank building located in Jackson,  Mississippi.  This building, along
with all other physical  properties of the  Corporation,  are owned by the Bank.
Approximately  155,000  square  feet  (55%) of the  available  space in the main
office building is allocated to bank use with the remainder  occupied by tenants
on a  lease  basis.  The  Bank  also  operates  109  full-service  branches,  22
limited-service branches, 11 in-store branches and an ATM network which includes
83 ATMs at on- premise  locations and 60 ATMs located at off-premise  sites. The
Bank leases 77 of its 185 locations with the remainder being owned.

ITEM 3. LEGAL PROCEEDINGS

     The  Corporation  and its  subsidiaries  are parties to lawsuits  and other
claims  that arise in the  ordinary  course of  business;  some of the  lawsuits
assert claims to the lending, collection, servicing, investment, trust and other
business  activities of the Bank;  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 the  Corporation's  consolidated  financial  position  or  results  of
operations.

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

     There were no matters  submitted to the Corporation's  shareholders  during
the fourth quarter of 1997.
