In addition, the Company is subject to risks and uncertainties that affect the manufacturing sector generally including, but not limited to, economic, competitive, governmental and technological factors affecting the Company's operations, markets, products, services and prices. Any such forward looking statements are not guarantees of future performances and actual results, developments and business decisions may differ from those envisaged by such forward looking statements. The Company disclaims any duty to update any forward looking statements, all of which are expressly qualified by the foregoing. ITEM 1. BUSINESS The Company conducts its operations through two business segments: Process/Environmental Controls and Tools and Components. Process/Environmental Controls The Process/Environmental Controls segment is comprised of the Fluke Corporation ("Fluke"), Veeder-Root Company ("Veeder-Root"), Danaher Controls, Partlow/West, Anderson Instruments, West Instruments, QualiTROL Corporation, A.L. Hyde Company, Hengstler, McCrometer, the controls product line business units of Joslyn Corporation and Pacific Scientific Company, Namco Controls, Dolan-Jenner, M&M Precision Systems, Communications Technology Corporation, Gems Sensors and Dr. Bruno Lange GmbH. These companies produce and sell compact, professional electronic test tools, underground storage tank leak detection systems and motion, position, speed, temperature, level and position instruments and sensing devices, power switches and controls, communication line products, power protection products, liquid flow and quality measuring devices, quality assurance products and systems, safety devices and electronic and mechanical counting and controlling devices. These products are distributed by the Company's sales personnel and independent representatives to original equipment manufacturers, distributors and other end users. The Company's strategy in the Process/Environmental Controls segment is to concentrate on the rapid expansion of its environmental controls product line, including the Veeder-Root storage tank leak detection systems business. The Company believes that Veeder-Root is the premier manufacturer of state-of-the-art tank measuring and leak detection systems for underground fuel storage tanks and, accordingly, is uniquely positioned to respond to the increased demand for these products. The Company is also expanding its other offerings in the environmental controls product line to encompass applications related to markets other than petroleum storage and to address nonregulatory business requirements. Offerings include analytical instruments for air and water quality monitoring. This expansion program includes both internally developed new product offerings as well as selective product line acquisitions. Fluke is engaged in the design, manufacture and marketing of compact, professional electronic test tools. Fluke's principal products are portable instruments that measure voltage, current, power quality, frequency, temperature, pressure and other key functional parameters of electronic equipment. Fluke distributes its products in over 100 countries, serving two major markets: industrial tools and networks. In its instruments product line, the Company's strategy is to continue enhancing its global controls and instrument position by both new product development and complementary acquisitions. Danaher's instrument companies have significant synergies in both product offerings and channels of distribution. The Company's plan is to leverage these synergies in product design, engineering and manufacturing, and product marketing. M&M Precision Systems provides both quality assurance products and systems which enhance both quality and manufacturing effectiveness as well as motion products which are generally components of other devices. Other business lines within this segment include extruded thermoplastic mill shapes and custom molded plastic products. In March, 1998, the Company acquired Pacific Scientific Company. Pacific Scientific has two major business segments: (i) Electrical Equipment and (ii) Safety Equipment. Nearly half of the company's sales consists of electric motors, drives and controls. These electric motors and controls are sold primarily to original equipment manufacturers who incorporate them into a wide variety of products. Pacific Scientific motors are used in factory automation, medical, printing, plastic extrusion and molding, paper converting, vending, textile, aerospace, fitness and many other types of equipment. Safety equipment includes mainly fire detection and suppression equipment, crew restraints, flight control and pyrotechnic devices. Safety equipment is sold mainly in the aviation and aerospace industry. The company also provides worldwide sales, service and repair of its products for airlines and other users of safety equipment. Operating results from Pacific Scientific have been included with the Company's results, beginning with the first quarter of 1998. The raw materials utilized by companies in this segment are stock items, principally metals and plastic, electrical and electronic components. These materials are readily available from a number of sources in sufficient quantities. Tools and Components The Tools and Components segment is comprised of the Danaher Hand Tool Group (including Special Markets, Professional Tool Division and Asian Tool Division), Matco Tools ("Matco"), Jacobs Chuck Manufacturing Company ("Jacobs"), Delta Consolidated Industries, Jacobs Vehicle Systems Company, Hennessy Industries and the hardware and electrical apparatus lines of Joslyn Manufacturing Company (JMC). This segment is one of the largest domestic producers and distributors of general purpose mechanics' hand tools and automotive specialty tools. Other products manufactured by these companies include tool boxes and storage devices, diesel engine retarders, wheel service equipment, drill chucks, custom designed headed tools and components, hardware and components for the power generation and transmission industries, high quality precision socket screws, fasteners, and high quality miniature precision parts. The Company's business strategy in this segment is focused on increasing sales to existing customers, broadening channels of distribution, developing new products, geographic expansion and achieving production efficiencies and enhanced quality and customer service through "Just-In-Time" and related manufacturing techniques. Danaher Tool Group (DTG) is one of the largest domestic producers of general purpose mechanics' hand tools (primarily ratchets, sockets and wrenches) and specialized automotive service tools for the professional and "do-it-yourself" markets. DTG has been the principal manufacturer of Sears, Roebuck and Co.'s Craftsman line of mechanics' hand tools for over 50 years. Approximately 80% of the over 100 million pieces sold to Sears annually are sold in tool sets that include from three to 900 pieces. Net sales to Sears were approximately 10% of total Company sales in 1998. DTG's Special Markets Group sells to Sears under a five year evergreen agreement, that requires Sears to purchase a significant portion of its annual requirements for its private-label Craftsman mechanics' hand tool line from DTG, subject to certain conditions. For over 30 years, DTG has also been a primary supplier of specialized automotive service tools to NAPA, which has approximately 6,500 outlets at present. In addition, DTG has been the designated supplier of general purpose mechanics' hand tools to NAPA since 1983. DTG specialized automotive service tools are also sold under the K-D Tools brand, its industrial tools and products are also sold under the Armstrong and Allen brand names, and fastener products under the Holo-Krome name are sold to independent distributors and other customers in the "do-it-yourself," professional automotive, commercial and industrial markets. Professional mechanics' tools are distributed by Matco which has approximately 1,300 independent mobile distributors who sell primarily to individual professional mechanics. Matco is one of the leading suppliers in this market. The Company believes Jacobs is the market leader in the drill chuck business with its highly respected and well recognized brand name. The Company believes Delta is the market leader in boxes and other storage containers serving the vehicle aftermarket and manufactures and markets containers serving numerous specialty areas. Wheel service equipment is manufactured under the Coats , Bada and Ammco brand names. Products include tire changers, wheel balancers, wheel weights and brake service equipment. Wheel service equipment is sold primarily to wholesale distributors and national accounts. These markets are served by the Company's sales personnel. Diesel engine retarders are manufactured at Jacobs Vehicle Systems Company. The "Jake Brake " technology was developed by Jacobs Vehicle and represents the leading brand of engine retarders. The product is sold by Jacobs' sales personnel to original equipment manufacturers and aftermarket distributors. JMC manufactures a wide variety of products used in the construction and maintenance of electric power, telephone and cable television systems. Its products range from specialized fasteners to sophisticated castings and forgings. JMC also manufactures surge protection devices for the electric power utility industry. The major raw materials used by this segment, including high quality steel, are available from a variety of sources in sufficient quantities. Patents, Licenses, etc. The Company has patents of its own and has acquired licenses under patents of others. The Company does not consider that its business, as a whole, is dependent on any single patent, group of patents, trademark or franchise. The Company does, however, offer many patented products and is periodically engaged in litigation concerning patents and licenses. Seasonal Nature of Business As a whole, the Company's businesses are not subject to material seasonal fluctuations. Backlog The Company's products are manufactured primarily in advance of order and either shipped or assembled from stock. Backlogs are not significant as sales are often dependent on orders requiring immediate shipment from inventory. Employee Relations At December 31, 1998, the Company employed approximately 18,000 persons. Of these, approximately 2,300 were hourly-rated unionized employees. The Company considers its labor relations to be good. Research and Development The Company's research and development expenditures were $111 million for 1998, $88 million for 1997 and $77 million for 1996. Environmental and Safety Regulations Certain of the Company's operations are subject to federal, state and local environmental laws and regulations which impose limitations on the discharge of pollutants into the air and water and establish standards for treatment, storage and disposal of solid and hazardous wastes. The Company believes that it is in substantial compliance with applicable environmental laws and regulations. JMC previously operated wood treating facilities that chemically preserved utility poles, pilings and railroad ties. All such treating operations were discontinued or sold prior to 1982. These facilities used wood preservatives that included creosote, pentachlorophenol and chromium-arsenic- copper. While preservatives were handled in accordance with then existing law, environmental law now imposes retroactive liability, in some circumstances, on persons who owned or operated wood-treating sites. JMC is remediating some of its former sites and will remediate other sites in the future. The Company has made a provision for environmental remediation; however, there can be no assurance that estimates of environmental liabilities will not change. In addition to environmental compliance costs, the Company may incur costs related to alleged environmental damage associated with past or current waste disposal practices or other hazardous materials handling practices. For example, generators of hazardous substances found in disposal sites at which environmental problems are alleged to exist, as well as the owners of those sites and certain other classes of persons, are subject to claims brought by state and federal regulatory agencies pursuant to statutory authority. The Company believes that its liability, if any, for past or current waste handling practices will not have a material adverse effect on its results of operation, financial condition and cash flow. The Company must also comply with various federal, state and local safety regulations in connection with its operations. The Company's compliance with these regulations has had no material adverse effect on its financial condition. Major Customers The Company has a customer in the tools segment, Sears, Roebuck and Co. ("Sears"), which accounted for 10% of consolidated sales in 1998. Although the relationship with Sears is long-standing, the Company believes the loss or material reduction of this business could have a material adverse effect on its operations. ITEM 2. PROPERTIES The Company occupies over 5 million square feet of manufacturing, distribution, service and office space at various domestic and foreign locations. The principal properties are listed below and are constructed of concrete, brick, cement, cinderblock or some combination of these materials. The Company believes that its plants have adequate productive capacity and are suitably used for the manufacture of its products and that its warehouses, distribution centers and sales offices are suitably located and utilized for the marketing of its products and services.

ITEM 3. LEGAL PROCEEDINGS A former subsidiary of the Company is engaged in litigation in several states with respect to product liability. The principal case, Patton, et al v. Chicago Pneumatic Tool Company, was filed in United States District Court in Jackson Co., MS in 1989. There are other related cases. The Company sold the subsidiary in 1987. Under the terms of the sale agreement, the Company agreed to indemnify the buyer of the subsidiary for product liability related to tools manufactured by the subsidiary prior to June 4, 1987. The cases involve approximately 3,000 plaintiffs, in state and federal courts. All other major U.S. air tool manufacturers are also defendants. The gravamen of these complaints is that the defendants' air tools, when used in different types of manufacturing environments over extended periods of time, were defective in design and caused various physical injuries. The plaintiffs seek compensatory and punitive damages. The Company's maximum indemnification obligation under the contract is approximately $85,000,000. The Company has accepted an agreement in principle to settle all claims. Completion of this settlement agreement will not result in a material adverse effect on the Company's results of operations or financial condition. JMC is a defendant in a class action tort suit, Henry L. Johnson, et. al. v. Lincoln Creosote Company, Inc., et. al., filed in the 26th Judicial District Court of the State of Louisiana, in Bossier Parish, Louisiana. The suit alleges exposure to chemicals and property devaluation resulting from wood treating operations previously conducted at a Louisiana site. Both the size of the class and the damages are uncertain. The Company has tendered the defense of the suit to its insurance carrier. JMC has reached agreement with its insurance carrier which fixes its liability for this matter to a stated amount which will not have a material adverse effect on the Company's results of operations or financial condition. In addition to the litigation noted above, the Company and its subsidiaries are from time to time subject to ordinary routine litigation incidental to their business. The Company believes that the results of the above noted litigation and other pending legal proceedings would not have a materially adverse effect on the Company's financial condition. ITEM 4.
