Exhibit 99 CHATTEM, INC. AUDIT COMMITTEE CHARTER I. PURPOSE The primary function of the Audit Committee is to assist the Board of Directors in fulfilling its oversight responsibilities by reviewing the financial information which will be provided to the Securities and Exchange Commission or the public, the systems of internal controls which management and the Board of Directors have established, and the auditing, accounting and financial reporting processes generally. It shall be the responsibility of the Audit Committee to maintain free and open means of communication between the Board of Directors, the independent auditor and management of the Company. The Audit Committee will seek to fulfill these responsibilities by carrying out the responsibilities and duties enumerated in Section V. of this Charter. II. COMPOSITION The Audit Committee shall be comprised of three or more directors as determined by the Board, each of whom shall be "independent directors" as defined by the rules of the National Association of Securities Dealers, Inc. ("NASD") on or before June 2001, unless the Board, under exceptional and limited circumstances, determines that membership on the Audit Committee by an individual who is not independent as defined by NASD rules is required by the best interests of the Company and its shareholders, and the Board discloses in the next annual proxy statement subsequent to such determination the nature of the relationship and the reasons for that determination. All members of the Audit Committee shall have a working familiarity with basic finance and accounting practices and shall be able to read and understand fundamental financial statements, and at least one member of the Audit Committee shall have accounting or related financial management expertise. Audit Committee members and the Committee Chairman shall be designated by the full Board of Directors. III. MEETINGS The Audit Committee shall meet at least two times annually, or more frequently as circumstances dictate.

In addition, the Audit Committee or at least its Chairman shall have discussions with the independent auditor and management quarterly to review the Company's financial statements. IV.
