Item 1.01. Entry into a Material Definitive Agreement

On March  8,  2005,  the  Board  of  Directors  of  Trustmark  Corporation  (the
Corporation)  and the Board of Directors of Trustmark  National  Bank (the Bank)
approved  recommendations  by the  Corporation's  Human Resource  Committee (the
Committee) for the 2005 management  incentive program (the 2005 Program) for the
Chief Executive Officer (CEO) and other named executive officers,  respectively.
Executive  management and certain senior officers of the Bank participate in the
2005 Program as recommended by the CEO and approved by the Committee.


The CEO's award will be  determined  under  Trustmark's  2005 program  utilizing
measured weightings for corporate performance, strategic operational drivers and
business unit goals. Under the plan, the CEO's target incentive is set at 70% of
base  compensation with a potential  maximum of 100% of base  compensation.  The
CEO's incentive award is weighted at 75% corporate  performance measuring actual
results for  earnings per share and return on equity to the  Corporation's  2005
profit  plan.  The  remaining  25% is  weighted on actual  results for  specific
strategic  operational drivers including operating  efficiency,  revenue growth,
credit  quality and net income after taxes  compared to the  Corporation's  2005
profit plan.

All named  executive  officers and other  participants  in the 2005 program have
been  assigned  a  target   annual  cash   incentive  as  a  percentage  of  the
participant's base compensation. Participants may earn incentive awards based on
quantitative  measures  including  corporate  performance,  strategic  corporate
drivers and business unit goals,  comparing actual results to the  Corporation's
2005 profit plan.  The weightings  for each  quantitative  measure for the named
executive officers are recommended by the CEO and approved by the Committee. The
CEO approves the  weightings for all other  participants.  The Committee and the
CEO may grant a  discretionary  award  for  additional  qualitative  performance
measurements. All incentive awards under the plan are expected to be paid in the
first quarter of 2006.

                                   SIGNATURES

Pursuant  to the  requirements  of the  Securities  Exchange  Act of  1934,  the
registrant  has duly  caused  this  report  to be  signed  on its  behalf by the
undersigned hereunto duly authorized.
