Report of Independent Registered Public Accounting Firm The Plan Administrator Trustmark 401(k) Plan: We have audited the accompanying statements of net assets available for benefits of Trustmark 401(k) Plan (the Plan) as of December 31, 2004 and 2003, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2004 and 2003, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic 2004 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic 2004 financial statements taken as a whole. /s/ KPMG LLP Jackson, Mississippi June 10, 2005 TRUSTMARK 401(K) PLAN Statements of Net Assets Available for Benefits December 31, 2004 and 2003 2004 2003 ------------ ------------ Investments, at fair value: Money market accounts $ 16,972,820 $ 14,944,873 Fixed income mutual funds 4,818,765 4,989,877 Common stock of Trustmark Corporation 56,205,226 55,284,620 Equity mutual funds 45,796,548 34,381,716 ------------ ------------ Total investments 123,793,359 109,601,086 ------------ ------------ Receivables: Employer contributions 172,635 231,240 Participants' contributions 196,834 191,042 Investment proceeds - 240,014 ------------ ------------ Total receivables 369,469 662,296 ------------ ------------ Net assets available for benefits $124,162,828 $110,263,382 ============ ============ See accompanying notes to financial statements.

TRUSTMARK 401(K) PLAN Notes to Financial Statements December 31, 2004 and 2003 (1) Plan Description The following description of Trustmark 401(k) Plan (the Plan) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. (a) General The Plan is a defined contribution plan established for the associates of Trustmark Corporation (the Company) and certain other associated companies. (b) Eligibility Effective January 1, 2004, the Plan was amended to provide eligibility for participation in elective deferrals by employees on the first day of the month after thirty days of employment. Prior to 2004, the Plan provided eligibility for participation on the first day of the month following the completion of at least 1,000 hours of service during the twelve-month period ending on the anniversary of a person's employment commencement date. (c) Plan Administration The Plan's record keeping and trustee functions are handled by Nationwide Life Insurance Company and Nationwide Trust Company. The plan administrator and sponsor is Trustmark Corporation, parent company of Trustmark National Bank. (d) Participants' Contributions The Plan allows participants to make voluntary before-tax salary deferral contributions, through payroll deductions, to separately invested funds in accordance with Section 401(k) of the Internal Revenue Code. If certain requirements of Internal Revenue Code Section 401(k) are not met in Plan operation, the salary deferral agreements of participants may, on a nondiscriminatory and uniform basis, be amended or revoked to preserve the qualified status of the Plan. Voluntary after-tax contributions by participants are not allowed. Participants may direct investment of their voluntary contributions among several investment options. Participants may elect to contribute up to 25% of eligible compensation each period, subject to regulatory limitations. Any excess contributions must be returned to the applicable participant by April 15 of the calendar year following the year of excess contributions. The Plan allows for rollover contributions from individual retirement accounts or other qualified plans. Provisions of the Plan allow participants who were age 50 years or older by the end of calendar year to make catch-up contributions to the Plan. Catch-up contributions represent associate compensation deferrals in excess of certain plan limits and statutory limits including IRS annual deferral limits. The IRS annual deferral limits and annual catch-up contribution limits for future years are indicated in the following schedule: Catch-up Calendar year Deferral limit contribution limit ------------- -------------- ------------------ 2003 $12,000 $2,000 2004 13,000 3,000 2005 14,000 4,000 2006 15,000 5,000 Thereafter Indexed in $500 Indexed in $500 increments increments (e) Employer Contributions Eligible participant contributions are matched by the employer at a rate of 100% of the first 3% and 50% of the next 3% of covered compensation. The employer may also make discretionary contributions. (f) Allocations Participant and employer contributions are allocated directly to each participant's account in accordance with the individual participant's elections. Forfeitures of nonvested employer discretionary accounts were used to reduce the employer match contribution (see note 1(g)). During 2003, the Plan utilized $134,678 in forfeitures to reduce employer contributions. (g) Vesting Participants are immediately vested in their voluntary contributions and the investment earnings and losses thereon. Effective January 1, 2004, participants became 100% vested in all employer contributions made on their behalf, including those non-vested contributions remaining in the Plan on January 1, 2004. Prior to January 1, 2004, as of the day of a participant's sixty-fifth birthday, such participant was entitled to retire from active service with the employer, and 100% of the value of the participant's share of the Plan became fully vested. A participant also vested 100% upon death or termination of employment due to permanent disability. Prior to January 1, 2004, participants vested in the employer discretionary contributions and allocated earnings or losses thereon as shown in the following schedule: Years vesting service Vested percentage --------------------- ----------------- Less than 5 0% 5 or more 100% In case of termination of the Plan, each participant's account became fully vested as of the date of such termination. (h) Payment of Benefits On retirement, death, disability, or termination of service, a participant may elect to receive a lump-sum distribution equal to his or her account balance or in installments. In addition, hardship distributions are permitted if certain criteria are met. (i) Plan Termination Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. However, no such action may deprive any participant or beneficiary under the Plan of any vested benefit. (2) Significant Accounting Policies (a) Basis of Presentation The Plan's financial statements are prepared using the accrual basis of accounting, with the exception of the payment of benefits, which are recognized as a reduction in the net assets available for benefits of the Plan as they are disbursed to participants. Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. (b) Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of net assets and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. (c) Valuation of Investments Investments are stated at fair value. The fair value of mutual funds and other securities traded on a national securities exchange are valued at the closing quoted market price on the last business day of the year. (d) Net Appreciation in Fair Value of Investments Net appreciation in fair value of investments, as recorded in the accompanying statement of changes in net assets available for benefits, includes changes in the fair value of investments acquired, sold, or held during the year. (e) Administrative Fees Administrative fees are paid by the Plan. All other fees, including professional fees, are paid by the Company. (3) Investments The fair value of individual investments that represent 5% or more of the Plan's net assets as of December 31, 2004 and 2003 are as follows: December 31, ---------------------------- 2004 2003 ----------- ----------- Investments at fair value as determined by quoted market price: Common stock of Trustmark Corporation $56,205,226 $55,284,620 Performance Funds Trust Mutual Funds: Large-Cap Equity Fund 7,872,865 7,120,723 Mid-Cap Equity Fund 8,500,519 7,402,858 Investments at cost, which approximates fair value: Federated Capital Preservation Fund 14,296,460 13,027,583 During 2004 and 2003, the Plan's investments (including investments bought and sold, as well as held during the year) appreciated in value as follows: December 31, ---------------------------- 2004 2003 ----------- ----------- Investments at fair value as determined by quoted market price: Common stock of Trustmark Corporation $ 3,331,570 $10,791,486 Mutual funds 2,899,081 6,367,639 ----------- ----------- Net appreciation in fair value of investments $ 6,230,651 $17,159,125 =========== =========== Effective January 1, 2004, the Plan provides participants the opportunity to annually elect whether cash dividends paid on employer stock will be invested in shares of employer stock within the individual participant's account or be paid to the participant in cash. (4) Income Tax Status The Internal Revenue Service has determined and informed the Company by a letter dated November 19, 2001, that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (IRC). The Plan has been amended since receiving the determination letter. However, the plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. (5) Related Parties Trustmark National Bank serves as the investment advisor for the Performance Funds Trust Mutual Funds. For the years ended December 31, 2004 and 2003, dividends of $1,418,868 and $1,347,219 were received by the Plan from the Company. (6) Contingencies The Company 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 various 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 the Company or the Plan's consolidated financial statements. (7) Subsequent Events On March 1, 2005, assets totaling $5,403,429 from the Dan Bottrell Agency, Inc. Profit Sharing 401(k) Plan and Trust, the sponsor of which is a subsidiary of Trustmark National Bank, were merged into the Plan.
