PART I

Emerson was incorporated in Missouri in 1890. Originally engaged in the manufacture and sale of electric motors and fans, Emerson subsequently expanded its product lines through internal growth and acquisitions. Emerson is now engaged principally in the worldwide design, manufacture and sale of a broad range of electrical, electromechanical and electronic products and systems.

The divisions of Emerson are organized into the following business segments based on the nature of the products and services provided: Process Control; Industrial Automation; Electronics and Telecommunications; Heating, Ventilating and Air Conditioning; and Appliance and Tools. Sales, earnings before interest and income taxes, and total assets attributable to each segment for the three years ended September 30, 2002, are set forth in Note 14 of Notes to Consolidated Financial Statements of the 2002 Annual Report, which note is hereby incorporated by reference. Information with respect to acquisition and divestiture activities by Emerson is set forth in Note 3 of Notes to Consolidated Financial Statements of the 2002 Annual Report, which note is hereby incorporated by reference.

Emerson's major requirements for basic raw materials include steel, copper, cast iron, aluminum and brass and, to a lesser extent, plastics and other petroleum-based chemicals. Emerson has multiple sources of supply for each of its major requirements and is not significantly dependent on any one supplier. The raw materials and various purchased components required for its products have generally been available in sufficient quantities. Emerson uses various forms of energy, principally natural gas and electricity, obtained from public utilities. A majority of the plants have the capability of being converted to use alternative sources of energy.

The Company has a number of patents, trademarks, licenses and franchises, obtained over a number of years and expiring at various times. While proprietary intellectual property is important to the Company, management believes the loss or expiration of any intellectual property rights would not materially impact the Company or any of its segments.

The estimated consolidated order backlog of the Company was $2,135 million and $2,072 million at September 30, 2001 and 2002, respectively. Nearly all of the September 30, 2002 consolidated backlog amount is expected to be shipped within one year. The estimated backlog by business segment at September 30, 2001 and 2002, follows (dollars in millions):

Emerson's businesses are highly competitive, and Emerson competes on product performance, quality, service or price across the industries and markets served. A significant element of the Company's competitive strategy is its objective to manufacture high quality products at the lowest relevant global cost. Although no single company competes directly with Emerson in all of the Company's product lines, various companies compete in one or more product lines. Some of these companies have substantially greater sales and assets than Emerson, and Emerson also competes with many smaller companies.

5

<PAGE>

The number of Emerson's competitors varies by product line, and management believes that Emerson has a market leadership position in many of these product lines.

Costs associated with Company-sponsored research, new product development and product improvement were $594 million in 2000 and 2001, and $530 million in 2002.

The Company's manufacturing locations generate waste, the treatment, storage, transportation and disposal of which are subject to federal, state and/or local laws and regulations relating to the protection of the environment. Compliance with laws regulating the discharge of materials into the environment or otherwise relating to the protection of the environment has not had a material effect upon Emerson's capital expenditures, earnings or competitive position. It is not anticipated that Emerson will have material capital expenditures for environmental control facilities during the next fiscal year.

Emerson and its subsidiaries had an average of approximately 111,500 employees during 2002. Management believes that the Company's employee relations are favorable. Some of the Company's employees are represented under collective bargaining agreements, but none of these is considered significant.

International sales were $5,894 million in 2000, $6,189 million in 2001 and $5,751 million in 2002, including U.S. exports of $1,049 million, $1,008 million and $946 million in 2000, 2001 and 2002, respectively. Although there are additional risks attendant to foreign operations, such as possible nationalization of facilities, currency fluctuations and restrictions on the movement of funds, Emerson's financial position has not been materially affected thereby to date. See Note 14 of Notes to Consolidated Financial Statements of the 2002 Annual Report for further information with respect to foreign operations.

Forms 10-K, 10-Q, 8-K and all amendments to those reports are available without charge through Emerson's Web site on the Internet as soon as reasonably practicable after electronically filed with, or furnished to, the Securities and Exchange Commission. They may be accessed as follows: http://www.gotoemerson.com

At September 30, 2002, Emerson had approximately 320 manufacturing locations worldwide, of which approximately 185 were located outside the United States, primarily in Europe and to a lesser extent in Asia, Canada and Latin America. The approximate number of manufacturing locations by business segment are: Process Control, 75; Industrial Automation, 85; Electronics and Telecommunications, 50; Heating, Ventilating and Air Conditioning, 55; and Appliance and Tools, 55. The majority of the locations are owned, with the remainder occupied under operating or capital leases. The Company considers its facilities suitable and adequate for the purposes for which they are used.

Emerson is a party to a number of pending legal proceedings, several of which claim substantial amounts of damages. There are no pending legal proceedings that management believes will be material in relation to the Company's business or financial position.

There were no matters submitted to a vote of security holders during the quarter ended September 30, 2002.
