FOR IMMEDIATE RELEASE
April 15, 2003

                   Trustmark Announces First Quarter Earnings

Jackson,  Miss. - Trustmark  Corporation  (NASDAQ:TRMK)  announced net income of
$24.5 million in the first quarter of 2003, which  represented basic and diluted
earnings per share of $0.41.  Earnings during the quarter  included a previously
announced  one-time  after-tax  charge  of $4.1  million,  or $0.07  per  share,
associated with the company's  voluntary early retirement  program.  Trustmark's
performance for the quarter ended March 31, 2003 resulted in a return on average
shareholders'  equity  of  14.88%  and a return  on  average  assets  of  1.40%.
Excluding  the one-time  charge for the early  retirement  program,  Trustmark's
performance for the first quarter resulted in a return on average  shareholders'
equity of 17.36% and a return on  average  assets of 1.63%.  At March 31,  2003,
Trustmark  reported  total loans of $4.6 billion,  total assets of $7.3 billion,
total deposits of $5.0 billion and shareholders' equity of $660.6 million.

Richard G. Hickson,  Chairman and Chief Executive Officer,  stated, "Despite the
challenging economic and geopolitical environments,  Trustmark has continued its
focus on providing banking and financial solutions for its customers.  Our loans
increased  approximately  $200 million  while  deposits grew nearly $350 million
when compared to figures one year  earlier.  We appreciate  the  confidence  our
customers have placed in Trustmark and the efforts our  associates  have made in
increasing customer satisfaction."

"During the first quarter,  we continued to proactively  manage our expense base
with the  completion of our  previously  announced  voluntary  early  retirement
program.  The benefits of this  program,  which was accepted by 116, or 4.75% of
our  workforce,  are  expected  to result in  significant  compensation  expense
savings  during the remainder of 2003.  These  compensation  savings should also
enhance earnings in 2004," said Hickson.

"The  continued  decline in interest  rates again  provided both  challenges and
opportunities  for  Trustmark.  The effect of continued  reductions in long-term
interest rates reduced the value of our mortgage servicing portfolio. During the
first quarter, Trustmark recorded a non-cash after-tax charge of $4.4 million to
recognize  this  reduction in value of our mortgage  servicing  portfolio due to
customers  taking advantage of the opportunity to refinance their home mortgages
to lower interest rates.  This non-cash charge against income could be reversed,
in whole or in part, if interest rates rise,  refinancing slows and the expected
life of home mortgages lengthens. The current low interest rate environment also
provided an opportunity to restructure a portion of our fixed income  investment
portfolio and reduce exposure to volatile  interest  rates.  During the quarter,
Trustmark realized an after-tax net gain of $5.3 million resulting from sales of
fixed income investment securities," Hickson said.

During  the first  quarter  of 2003,  Trustmark  repurchased  approximately  1.3
million  shares  of  its  common  stock.  At  March  31,  2003,   Trustmark  had
authorization  to  repurchase  up to  an  additional  1.6  million  shares.  The
repurchase program is subject to market conditions and management discretion and
will  continue to be  implemented  through  open market  purchases  or privately
negotiated transactions.

Trustmark  is a financial  services  company  providing  banking  and  financial
solutions  through  over 130 offices and 2,300  associates  in  Mississippi  and
Tennessee.   For  additional   information,   visit   Trustmark's  web  site  at

NOTES TO CONSOLIDATED FINANCIAL INFORMATION

Note 1 - Business Combinations

     On  June  28,  2002,  The  Bottrell  Insurance  Agency,  Inc.,  a
     wholly-owned  subsidiary  of Trustmark  National  Bank,  acquired
     Chandler-Sampson  Insurance, Inc. (CSI) in Jackson,  Mississippi.
     This  business  combination,  which is not material to Trustmark,
     was accounted for under the purchase  method of  accounting.  The
     shareholders  of CSI  received  $8 million in cash in  connection
     with the merger.  Excess cost over  tangible net assets  acquired
     totaled $10 million, of which $3 million and $7 million have been
     allocated to other  identifiable  intangible assets and goodwill,
     respectively.

Note 2 - Early Retirement Program

     In  February  2003,   Trustmark   announced  a  voluntary   early
     retirement program (ERP) for associates age 58 and above with ten
     or more  years of  service.  This  program  was  accepted  by 116
     associates,   or  4.75%  of  Trustmark's  workforce.  A  one-time
     after-tax  charge of  approximately  $4.1  million,  or $0.07 per
     share, was recognized in Trustmark's first quarter 2003 earnings.
     The following table  demonstrates  the effects of this program on
     Trustmark's results of operations and ratios:

Note 3 - Efficiency Ratio Calculation

     The efficiency ratio is calculated by dividing total  noninterest
     expense by  tax-equivalent  net interest income plus  noninterest
     income,  excluding  security  gains and  demonstrates  how much a
     company spends for each dollar of revenue earned.  The efficiency
     ratio has been adjusted for the following transactions:
