ITEM 1.  BUSINESS

GENERAL

         Trustmark  Corporation  (Trustmark) 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.  Trustmark's  primary
business activities are conducted through its wholly-owned subsidiary, Trustmark
National  Bank (the Bank) and the Bank's  wholly-owned  subsidiaries,  Trustmark
Financial  Services,  Inc. (TFSI) and Trustmark  Insurance Agency, Inc. The Bank
accounts  for  substantially  all of  the  assets  and  revenues  of  Trustmark.
Chartered by the State of  Mississippi  in 1889,  the Bank is  headquartered  in
Jackson,  Mississippi and is the largest bank in the state.  Trustmark 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.
         Trustmark  provides a broad array of traditional  banking  products and
services  primarily  to  customers  in  Mississippi  through  its network of 140
branches  and  147  ATMs.  In  order  to  service  Retail  clients'  needs  more
effectively, Pinnacle, a proactive client-focused sales process, was implemented
during 1998. As a result of Pinnacle,  Trustmark  associates have a higher level
of client knowledge and understand the financial alternatives best suited to the
client's needs. In addition,  improvements to Trustmark's delivery channels have
expedited communication and information flow to the point of sale thus providing
faster and more convenient transactions for clients. In order to allow customers
to do their  banking  around the clock from their  homes or  offices,  Trustmark
offers the  TrustTouch  automated  response  system.  Customers  may also obtain
information  about  Trustmark's  services via the Internet by accessing  its web
site (www.trustmark.com). Trustmark's Card Services offer MasterCard, VISA, VISA
Gold  and  VISA  Business  credit  card  services  to  consumers  and  merchants
throughout  Mississippi.  Trustmark's  ExpressCheck debit card allows clients to
conveniently pay for purchases from merchants, withdraw cash from



automated  teller machines and receive  account balance  information or transfer
funds between their accounts at their convenience. For many years, Trustmark has
been active in automobile  finance  directly  throughout  its  extensive  branch
network as well as through a  long-established  indirect  network of  automobile
dealers.  Home  mortgage  lending  increased  significantly  during 1998 and has
strengthened  Trustmark's  position  as a  premier  home  lender.  In  addition,
Trustmark's  home  mortgage  department  services more than $3.4 billion in home
loans throughout the Southeast.
         Trustmark  provides  loans,  deposit  services and cash  management for
Mississippi  businesses.  Cash  management  services  offers new  technology and
services for businesses to monitor cash flow through the utilization of TrustNet
computer banking,  automated clearing services which facilitates electronic bill
payment  and direct  deposit of  employee  pay and Trustmark's Mutual Fund Sweep
account. Trustmark offers commercial real estate loans targeting the residential
real  estate  development  and  construction  markets.  Trustmark  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.  Trustmark's  Correspondent  Banking  Department
maintains  relationships  with  independent  banks  across the state,  providing
competitively priced cash management services,  financing and clearing services.
Trustmark's  public services bankers offer cash management  products,  loans and
investment  services  tailored  for the needs of public  entities  such as state
agencies, municipal government and school districts.
         Trustmark  offers a broad  line of  banking, investment  and  insurance
products designed to meet the objectives of retail and commercial clients. These
products  include the  Performance  Funds, a family of six mutual funds designed
and managed by Trustmark investment professionals, as well as personal trust and
asset  management,  employee  benefits and corporate trust. With $5.4 billion in
trust assets under  administration,  Trustmark's  Trust Department offers a full
line of asset  management  and custodial  services  through its Personal  Trust,
Employee  Benefit and  Corporate  Trust  groups.  TFSI,  Trustmark's  investment
brokerage  subsidiary,  expanded its product  offering  and delivery  network in
1998. TFSI currently has 16 locations across the state of Mississippi and offers
a comprehensive range of brokerage services. In 1999, Trustmark will address the
insurance  needs of clients by broadening  the products and services  offered by
its insurance subsidiary, Trustmark Insurance Agency, Inc.
         As of March 11, 1999,  Trustmark  and the Bank  employed  approximately
2,250 full-time equivalent employees.

COMPETITION

         Trustmark 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,  consumer finance  companies,  mortgage
companies,  insurance  companies,  brokerage firms,  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

         Trustmark is a registered  bank holding  company under the Bank Holding
Company  Act of 1956,  as  amended.  As such,  Trustmark  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,  Trustmark 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
Trustmark'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.

         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 2.24 years.
         As of December 31, 1998, the Corporation  held securities of one issuer
with a carrying  value  exceeding  ten  percent of total  shareholders'  equity.
General  obligations  of the  State  of  Mississippi  with a  carrying  value of
$109,378,000 and an approximate fair value of $115,435,000 were held on December
31, 1998. Included in the aforementioned State of Mississippi holdings are bonds
with an aggregate carrying value of $17,028,000 and an approximate fair value of
$19,429,000 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 either
guaranteed or 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, 1998 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

         The  allowance  for  loan  losses  is  maintained  at a level  believed
adequate by  Management  to absorb losses  inherent in the loan  portfolio.  The
level of the  allowance  is based on  Management's  periodic  evaluation  of the
portfolio, the Corporation's past loan loss experience, known and inherent risks
in the portfolio,  composition of the portfolio,  current  economic  conditions,
review  of  specific  criticized  credits  and  other  relevant  factors.   This
evaluation  is  inherently  subjective  as it requires  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, 1998. These allocations
were determined  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                                      $ 34,223
   Additional allocation for
     risk-rated loans                                         1,621
   Allocation for selected
     industries                                               4,096
   General allocation for
     all other loans                                         11,235
   Allocation for available lines
     of credit and letters of credit                          3,214
   Unallocated                                               11,761
                                                            -------
     Total                                                  $66,150
                                                            =======

         The allowance for loan losses is maintained at a level which Management
and the Board of Directors  believe is adequate to absorb 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  are  uniformly  applied  to pools of  risk-rated  loans  within the
commercial  portfolio.  These  percentages  are  determined  based on  migration
analysis,  previously established floors for each category and economic factors.
In addition,  relationships of $500,000 or more which are risk-rated Other Loans
Especially  Mentioned or Substandard  and all which are risk-rated  Doubtful are
reviewed by the  Corporation's  Internal  Asset  Review  staff to  determine  if
standard  percentages  appear to be  sufficient  to cover  inherent loss on each
line. In the event that the percentages on any particular  lines were determined
to be insufficient,  additional  allocations are made based upon recommendations
of lending and asset review personnel.
         Industry  allocations are 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  inherent
losses within  portions of the loan  portfolio  not addressed in the  preceeding
allocations.  The  types  of  loans  included  in  the  general  allocation  are
residential  mortgage loans,  direct and indirect  consumer  loans,  credit card
loans and  overdrafts.  The  actual  allocation  amount  is based  upon the more
conservative of: loss experience  within these  categories  during the year, 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 are the
same as those applied to the funded  portions of the  commercial and retail loan
portfolios, are applied to cover any potential losses in these off-balance sheet
categories.
         The  remaining  $11.8  million  is  unallocated   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.

         The table  below  shows  maturities  on  outstanding  time  deposits of
$100,000 or more at December 31, 1998 ($ in thousands):

TABLE 12 - SHORT-TERM BORROWINGS

         The  table  below   presents   certain   information   concerning   the
Corporation's  short-term  borrowings  for  each of the last  three  years ($ in

    Amount outstanding at end of period                 $1,318,545    $  948,700    $  967,191
    Weighted average interest rate at end of period           4.48%         5.72%         5.46%
    Maximum amount outstanding at any
      month end during each period                      $1,544,385    $1,003,907    $1,036,564
    Average amount outstanding during each period       $1,151,920    $  912,089    $  969,413
    Weighted average interest rate during each period         5.11%         5.18%         5.02%


         No other category of short-term  borrowings is required to be disclosed
because the average balance was less than 30% of shareholders' equity at the end
of 1998.



ITEM 2. PROPERTIES

         Trustmark's  principal  offices  are housed in a  14-floor  combination
office and bank building located in Jackson,  Mississippi and owned by the Bank.
Approximately  174,000  square  feet  (61%) 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  108  full-service  branches,  21
limited-service branches, 11 in-store branches and an ATM network which includes
84 ATMs at on-premise  locations and 63 ATMs located at off-premise  sites.  The
Bank leases 68 of its 184 locations with the remainder being owned.

ITEM 3. 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,  that the  final
resolution  of pending  legal  proceedings  will not have a  material  impact on
Trustmark'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 Trustmark's  shareholders during the
fourth quarter of 1998.
