2004 Committee Charter : TRMK

The Audit and Finance Committee (the Committee) is a committee of the
Board of Directors. Its primary function is to assist the Board in fulfilling
its oversight responsibilities by monitoring Trustmark's accounting and
financial reporting process, the systems of internal controls that management
and the Board of Directors have established, and the audit process. The
Committee is neither intended nor equipped to guarantee with certainty to the
full Board and shareholders the accuracy and quality of Trustmark's financial
statements and accounting practices. Proper financial reporting, accounting, and
audit functions are collaborative efforts conducted by full-time professionals
dedicated to these purposes. The Committee oversees the work of others involved
in the financial reporting process-management, including the internal auditor,
and the independent accountant - and assesses practices and safeguards, and
encourages procedures that promote accountability on the part of the full-time
professionals.
Audit and Finance Committee members shall meet the requirements of the
National Association of Securities Dealers and the Securities and Exchange
Commission. The Audit and Finance Committee shall be comprised of three or more
Directors as determined by the Board, each of whom shall be independent
directors, free from any relationship that would interfere with the exercise of
his or her independent judgment. No member of the Committee shall participate in
the preparation of the financial statements of the company or any of its
subsidiaries. Audit and Finance Committee members must not accept any
consulting, advisory, or other compensatory fees from the company other than for
board service, and they must not be an affiliated person of the company. All
members of the Committee shall have a basic understanding of finance and
accounting and be able to read and understand fundamental financial statements,
including Trustmark's balance sheet, income statement and cash flow statement
and at least one member of the Committee shall meet the requirements of an audit
committee financial expert as defined, or the reasons why not will be disclosed.
Audit and Finance Committee members shall be appointed by the Board of
Directors on recommendation of the Executive Committee. If an Audit and Finance
Committee chairperson is not designated or present, the members of the Committee
may designate a chairperson by majority vote of the Committee membership.
The Committee shall meet at least five times annually, or more frequently
as circumstances dictate. The Audit and Finance Committee chairperson shall
prepare or approve an agenda in advance of each meeting. The Committee shall
meet privately on a regular basis with management, the director of the internal
auditing department, the independent accountants, and as a committee to discuss
any matters that the Committee or each of these groups believe should be
discussed. The Committee shall provide an open avenue of communication between
the internal auditors, the independent accountant, management, and the Board of
Directors.
The Committee shall have the power, including funding, to conduct or
authorize investigations into any matters within the Committee's scope of
responsibilities. The Committee shall be empowered to retain independent
counsel, accountants, or others to assist it in the conduct of any
investigation.
