Exhibit 99.4 CHARTER AND OPERATING GUIDELINES Audit and Finance Committee (Audit Capacity) The ServiceMaster Company (July 19, 2002) The Board of Directors of the Company has developed and approved this Charter and Operating Guidelines to articulate its understanding of the important role of the Committee in its capacity as an audit committee of the Board. Through it, the Board has sought to develop a clear mission and to establish practices and policies for the Committee. The primary purpose of the Committee is to assist the Board in its oversight responsibilities to the shareholders, to potential shareholders and to the investment community regarding the quality and integrity of the financial reports and the underlying control structure of the Company. The authority, responsibilities and membership of the Committee are set forth in the bylaws of the Company. It is the intent of this Charter to clarify the relationship of the Committee to: the Board of Directors, management (including the Internal Auditor), and the Company's Independent Auditor. These matters are presented in the context of "Expectations" from and to each of these entities. While the Committee has the responsibilities set forth in this Charter, it is not the duty of the Committee to plan or conduct audits or to determine that the Company's financial statements are complete and accurate and in accordance with generally accepted accounting principles. This is the responsibility of management and the Independent Auditor. Nor is it the duty of the Committee to conduct investigations, resolve disagreements, if any, between management and the Independent Auditor or to assure compliance with laws and regulations and the Company's business guidelines. I. BOARD EXPECTATIONS OF THE AUDIT COMMITTEE A.
