FOR IMMEDIATE RELEASE
April 20, 2004

                   Trustmark Announces First Quarter Earnings
         Earnings per share rise 12.2%, Loans and Deposits increase 12%

Jackson, Miss. - Trustmark Corporation (NASDAQ:TRMK) announced basic and diluted
earnings per share of $0.46 for the first  quarter of 2004,  which  represents a
12.2% increase compared to $0.41 for the first quarter of 2003. During the first
three months of 2004,  earnings  totaled $26.8  million,  up 9.3% from the prior
year.  Trustmark's  first  quarter  net income  produced  annualized  returns on
average   shareholders'   equity  and  average   assets  of  15.27%  and  1.36%,
respectively. At March 31, 2004, Trustmark reported total loans of $5.2 billion,
total assets of $8.1 billion,  total deposits of $5.6 billion and  shareholders'
equity of $719 million.

Richard G. Hickson,  Chairman and CEO of Trustmark Corporation,  remarked,  "Our
expansion  efforts in Houston  and the  Florida  panhandle  have made  important
contributions to Trustmark's  growth. Our loans have increased $567 million,  or
12.2%, while deposits grew $597 million,  or 12.0%, when compared to figures one
year  earlier.  We  appreciate  the  confidence  our  customers  have  placed in
Trustmark and commend our associates for their  dedication to becoming a premier
financial services company in our marketplace."

Like many other financial  services  firms,  fluctuations in interest rates have
reduced the profitability of Trustmark's home mortgage lending business.  Higher
home  mortgage  rates  during most of the first  quarter  resulted in lower loan
originations,  which  reduced home mortgage  banking  income.  In addition,  the
decline in the 10-year U.S.  Treasury  rate in  mid-March  resulted in increased
amortization and impairment in the value of our home mortgage  servicing rights.
The increase in  amortization  and  impairment  from the prior  quarter  reduced
Trustmark's  first  quarter  earnings  by $2.7  million  after tax, or $0.05 per
share.  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
mortgage loans lengthens.

Trustmark  is a financial  services  company  providing  banking  and  financial
solutions through over 145 offices and 2,400 associates in Mississippi, Florida,
Tennessee and Texas. For additional  information,  visit Trustmark's web site at

NOTES TO CONSOLIDATED FINANCIALS

Note 1- Business Combinations

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 in 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 were written down to their 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 core
deposits and goodwill,  respectively.  Trustmark's  financial statements include
the results of operations for this acquisition from the merger date.

On August 29,  2003,  Trustmark  acquired  seven  Florida  branches  of The Banc
Corporation of Birmingham,  Alabama, in a business combination  accounted for by

Division,  serve the markets from Destin to Panama City. In connection  with the
transaction,  Trustmark  paid a $46.8  million  deposit  premium in exchange for
$232.8 million in assets and $209.2  million in deposits and other  liabilities.
Assets  consisted  of $224.3  million in loans,  $6.8  million in  premises  and
equipment and $1.7 million in other assets.  These 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 $1.9  million  discount,
consisting  of a discount for general  credit risk of $3.5  million  offset by a
market valuation premium of $1.6 million.  Excess costs over tangible net assets
acquired  totaled  $49.5  million,  of which $1.7 million and $47.8 million have
been  allocated  to  core  deposits  and  goodwill,  respectively.   Trustmark's

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

Loans are stated at the amount of unpaid principal,  adjusted for the net amount
of direct costs,  nonrefundable  loan fees and discounts on purchased  loans. As
mentioned in Note 1,  Trustmark  purchased  $370.2  million in net loans through
branch purchase  acquisitions in Florida and Texas. The discount associated with
the acquired loans, which is netted against unpaid principal,  was $10.8 million
and will be accreted  into income over the life of the specific  loans  acquired
for loans which are expected to be fully  collected.  Unpaid  principal on loans
that are not  expected to be fully  collected  will be written  down against the
recorded discount.

The allowance for loan losses is  established  through  provisions for estimated
loan losses  charged  against  earnings and is  maintained  at a level  believed
adequate by Management to absorb estimated probable loan losses. However, in the
case of the acquired  loans in Florida and Texas,  no specific loan loss reserve
was required under generally accepted accounting principles at the purchase date
because the loans were  purchased at a discount which  considered  interest rate
and credit  risk.  As a result,  the ratio of the  allowance  for loan losses to
loans has decreased to 1.43% (see pages 3 and 6) for the quarter ended March 31,
2004.


Note 3 - Mortgage Servicing Rights

For the periods presented,  the carrying amount of mortgage servicing rights are
as follows:

                                      3/31/2004    12/31/2003     3/31/2003

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 new
servicing income. At March 31, 2004 Trustmark  serviced $3.4 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.  Trustmark  would  expect to recover a  significant
portion of the valuation  allowance  when mortgage  rates increase and stabilize
and  prepayment  speeds  decrease.  Since March 31,  2004,  mortgage  rates have
increased to December 2003 levels which would eliminate the impairment  recorded
through other expenses for the quarter ended March 31, 2004.
