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.
