Business (a) General Development of Business Thermo Optek Corporation (the Company or the Registrant) is a worldwide leader in the development, manufacture, and marketing of analytical instruments and has technologies in electro-optic components and systems. The Company's instruments are used in the quantitative and qualitative chemical analysis of elements and molecular compounds in solids, liquids, and gases. These products are used by its customers for productivity enhancement, research and development, quality control, and testing applications in the environmental testing, chemical, metallurgical, food and beverage, pharmaceutical, and petroleum industries; and by forensic laboratories, research organizations, and educational institutions. The Company was incorporated in Delaware in August 1995 as a wholly owned subsidiary of Thermo Instrument Systems Inc. (Thermo Instrument). Thermo Instrument is a publicly traded, majority-owned subsidiary of Thermo Electron Corporation (Thermo Electron). An element of the Company's strategy is to combine its internal growth with the acquisition of complementary products and technologies. In December 1995, Thermo Instrument acquired the assets of the analytical instruments division of Analytical Technology, Inc. (the ATI Division), a manufacturer of analytical instruments, for $42.5 million. In April 1996, the Company acquired the ATI Division's Mattson and Unicam businesses from Thermo Instrument for an aggregate purchase price of $36.6 million. These businesses have been included in the Company's historical results of operations from December 1, 1995, the date on which they were acquired by Thermo Instrument. Mattson is a Wisconsin-based manufacturer of FT-IR spectroscopy instruments and Unicam is a Cambridge, UK-based manufacturer of atomic absorption and ultraviolet/visible spectroscopy instruments. Effective March 29, 1996, the Company acquired two businesses, A.R.L. Applied Research Laboratories S.A. (ARL) and VG Elemental, and four associated sales organizations located in South Africa, Austria, Sweden, and Canada from Thermo Instrument for approximately $55.2 million in cash and the assumption of $16.6 million in debt. These businesses were originally part of the Scientific Instruments Division of Fisons plc (Fisons), a wholly owned subsidiary of Rhone-Poulenc Rorer, Inc., a substantial portion of which was acquired by Thermo Instrument on March 29, 1996. The purchase price is subject to a post-closing adjustment based on a post-closing adjustment to be negotiated with Fisons by Thermo Instrument in connection with the negotiations for settlement of the final purchase price for all of the businesses of Fisons acquired by Thermo Instrument. ARL is a Switzerland-based manufacturer of arc/spark AE spectrometers and X-ray fluorescence instruments. VG Elemental is a U.K.-based manufacturer of inductively coupled plasma/mass spectrometers. In June and July 1996, the Company sold 3,450,000 shares of its common stock in an initial public offering at $13.50 per share for net proceeds of $42.9 million. In October 1995, the Company issued and sold 2PAGE $96.3 million principal amount of 5% subordinated convertible debentures due 2000. The debentures are convertible into shares of the Company's common stock at a conversion price of $14.85 per share and are guaranteed on a subordinated basis by Thermo Electron. As of December 28, 1996, Thermo Instrument owned 45,000,000 shares of the common stock of the Company, representing 93% of such stock outstanding. Thermo Instrument develops, manufactures, and markets instruments used to detect and measure air pollution, radioactivity, complex chemical compounds, toxic metals, and other elements in a broad range of liquids and solids, as well as to control and monitor various industrial processes. As of December 28, 1996, Thermo Electron owned 144,900 shares of the common stock of the Company, representing 0.3% of such stock outstanding. These shares were purchased during 1996* in the open market for a total purchase price of $1,967,000. Thermo Electron is a world leader in environmental monitoring and analysis instruments, biomedical products such as heart-assist devices and mammography systems, paper-recycling and papermaking equipment, biomass electric power generation, and other specialized products and technologies. Thermo Electron also provides a range of services related to environmental quality.

(b) Financial Information About Industry Segments The Company is engaged in one business segment: developing, manufacturing, and selling analytical instruments. (c) Description of Business (i) Principal Products and Services Analytical instruments are generally classified by their principal operating technologies. The Company's atomic emission (AE) and atomic absorption (AA) spectrometers comprise its elemental analysis product line, and FT-IR and FT-Raman spectrometers comprise its molecular analysis product line. In addition, through its Thermo Vision Corporation (Thermo Vision) subsidiary, the Company addresses the photonics marketplace for optical components, imaging systems, analytical * References to 1996, 1995, and 1994 herein are for the fiscal years ended December 28, 1996, December 30, 1995, and December 31, 1994, respectively. 3PAGE instruments, and lasers. Thermo Vision develops and manufactures cost-effective, application-specific instruments, as well as components, systems, and subassemblies for analytical instruments. Elemental Analysis - AE and AA Spectrometers The Company produces a range of AE and AA spectrometers that are used to detect and measure metals and other elements in solid and liquid samples from ultratrace (parts per billion) to major concentrations. These instruments are used in a wide variety of applications, including testing environmental samples, such as soil and water, and food and drugs; analyzing blood, urine, and animal tissue; and process quality control and product quality assurance. The Company sells its products to customers in a wide range of industries, including those in manufacturing industries such as producers of aircraft, automobiles and trucks, computers, chemicals, food, pharmaceuticals, and primary metals; service industries such as waste management companies and commercial testing laboratories; and government and university laboratories. In AE spectrometers, the samples are excited by an energy source, causing the sample atoms to emit radiation. The radiation is then dispersed by a grating into its component light wavelengths, which are detected by a photo multiplier tube or a solid state detector. Each element has a characteristic wavelength that acts as a "fingerprint" for that element, which the instrument compares against a library of spectra for identification. The resulting data may be stored and manipulated by computer. AE spectrometers use either an electrical discharge (arc/spark) or a high frequency inductively coupled plasma (ICP) as the energy source. Arc/spark instruments are used primarily for solid samples in highly capital-intensive processes such as steel and other primary metal production, foundries that fabricate raw metals, and production of products such as pipe and machine parts. Customers in these industries use the arc/spark instrument in near line quality control as part of the production process. Due to the high cost of these processes, the minimization of downtime and the maintenance of quality control are critical. For these reasons, reliability is frequently the most important feature to an arc/spark user. ARL, acquired in 1996, is a worldwide supplier of spectrochemical instrumentation based on arc/spark optical emission spectrometry and wavelength dispersive x-ray fluorescence (WDXRF) spectrometry. WDXRF spectrometers offer elemental analysis of a wide variety of materials in a highly precise and generally nondestructive manner. ICP spectrometers are used for both solid and liquid samples and allow for simultaneous multi-element testing. The largest users of ICP instruments are public and private environmental laboratories, which must test for multiple elements but which have well defined testing objectives. These users test for compliance with applicable environmental regulations, which prescribe the specific pollutants and concentrations to be identified. The Company has recently developed the first ultratrace ICP spectrometer that incorporates a solid state detector, the IRIS(TM), and the first combined optical emission mass spectrometer, the POEMS(R), which allows customers to perform with one instrument analyses that 4PAGE previously would have required multiple instruments. In addition, the IRIS incorporates Windows(TM)-based software that facilitates use of the instrument with relatively minimal training. ICP instruments can also be coupled with a mass spectrometer (ICP/MS) to provide detection at the parts per trillion level. This high level of sensitivity is often required by semiconductor, pharmaceutical, and chemical companies in both research and development and quality control functions. The Company has recently introduced the second generation of its POEMS ICP/MS, which incorporates several significant advances, including automated sample preparation and Windows-based software. POEMS is the first ICP/MS instrument to integrate a CID detector, which enhances the flexibility of the instrument. VG Elemental, acquired in November 1996, manufactures ICP/MS instruments that are utilized in the environmental, nuclear, semiconductor, biological, metals, and chemicals industries where critical, ultratrace detection of elements is required. Due to their sensitivity and relatively low cost, AA spectrometers are the instrument of choice for environmental applications. Certain of the EPA's protocols for the determination of toxic metals in water and wastes are written for AA spectrometers. In addition to environmental testing, AA spectrometers are used in biological testing and for testing in the agricultural and petroleum industries. AA spectrometers use a graphite furnace or flame to heat the sample and incorporate a hollow cathode lamp that contains the element to be measured. Because the hollow cathode lamp radiates at the same wavelength as the sample atoms, the sample atoms absorb radiation from the lamp, and the detector measures this absorption. The 1996 acquisition of Unicam has increased the Company's product base in AA spectrometers, as well as its presence in the European market, and will complement its other products and presence in the environmental, life science research, pharmaceutical, and chemical markets. Molecular Analysis - FT-IR and FT-Raman Spectrometers Thermo Optek is among the world's largest manufacturers of molecular analysis instruments that utilize FT-IR and FT-Raman spectroscopic techniques. Using these "vibrational" spectroscopic techniques, customers are able to nondestructively analyze liquids and solids for their molecular composition. These techniques permit the analysis of samples in their packaging, which eliminates much of the time involved with sample preparation. The Company's FT-IR and FT-Raman spectrometers are used principally in research and development and quality control in a variety of industries. Chemical and pharmaceutical companies use FT-IR and FT-Raman spectrometers for verification, identification, and quantification of chemical materials and mixtures because of the superior ability of these instruments to provide detailed structural information. Other applications involve analysis of total petroleum hydrocarbon content and other contamination in soil and water, and monitoring of industrial waste streams. The Company also offers several lines of infrared microscopes and micro-imaging accessories. The Company believes it is the world's leading supplier of these devices, which are utilized, individually or in 5PAGE conjunction with FT-IR spectrometers, to obtain the infrared spectrum of small samples in the range from 20 to 1000 microns. Thermo Vision Corporation Through its Thermo Vision subsidiary, the Company addresses the photonics marketplace for optical components, imaging systems, analytical instruments, and lasers. Thermo Vision is pursuing applications of its photonics technologies in a wide array of markets such as dental imaging, semiconductor processing, high-energy physics, and nuclear inspection, in addition to analytical instrumentation. Within instrumentation, Thermo Vision addresses the market for cost-effective, application-specific instruments and for optical components, systems, and subassemblies for analytical instrumentation. The Company believes that there is a trend in the market for analytical instruments toward the development of lower-cost instruments that are easy to use and capable of performing discrete analyses accurately and reliably. Thermo Vision is building a sales and service channel for optical components and lower-cost instruments that cannot be effectively or profitably sold or serviced through the channels used for larger, higher-performance analytical instruments. In February 1996, Thermo Vision acquired Corion Corporation (Corion), a manufacturer of commercial optical filters, for $5.1 million in cash and Oriel Corporation (Oriel), a manufacturer and distributor of electro-optical instruments and components, for $11.8 million in cash and the assumption of $0.7 million in debt. In addition, Thermo Vision acquired Laser Science, Inc. (LSI), a manufacturer of nitrogen, tunable dye, and pulsed lasers, in February 1997 for $3.6 million in cash. The Company believes that these acquisitions will further Thermo Vision's strategic move into the photonics marketplace by broadening its product offerings and providing a base for low-cost distribution. In 1996 and 1995, the Company derived revenues of $30.5 million and $6.1 million, respectively, from its Thermo Vision businesses. In September 1996, the Company announced its intent to spin out Thermo Vision through a distribution of all of its outstanding capital stock in the form of a dividend to the Company's shareholders. The Company anticipates completing the spinout in 1997, and is seeking a Letter Ruling from the Internal Revenue Service stating that the proposed spinout will have no current tax effect on Thermo Optek or its shareholders. The Company would distribute the shares upon receipt of the Letter Ruling and satisfaction of other conditions, including the listing of the Thermo Vision shares on the American Stock Exchange. Upon completion of this proposed transaction, Thermo Vision would be a majority-owned subsidiary of Thermo Instrument. Sales and Marketing The Company markets its instruments internationally through its own worldwide sales force and through a network of dealers and distributors. In addition, the Company sells certain components and instruments pursuant to original equipment manufacturer (OEM) arrangements under which third parties purchase and resell the Company's products. The 6PAGE Company's sales force is supported throughout the world by a customer support group which provides training, instrument servicing, and parts replacement. (ii) and (xi) New Products; Research and Development The Company maintains active programs for the development of new technologies and the enhancement of existing products. In addition, the Company seeks to develop new applications for its products and technologies. Research and development expenses for the Company were $22.0 million, $13.0 million, and $10.5 million in 1996, 1995, and 1994, respectively. (iii) Raw Materials Raw materials, components, and supplies purchased by the Company are either available from a number of different suppliers or from alternative sources that could be developed without a material adverse effect on the Company. To date, the Company has experienced no difficulties in obtaining these materials. (iv) Patents, Licenses, and Trademarks The Company's policy is to protect its intellectual property rights, including applying for and obtaining patents when appropriate. The Company holds numerous patents relating to its technologies, with additional patents pending. The Company also enters into licensing agreements with other companies and government agencies in which it grants or receives rights to specific patents and technical know-how. The Company also considers technical know-how, trade secrets, and trademarks to be important to its business. (v) Seasonal Influences There are no significant seasonal influences on the Company's sales of its products. (vi) Working Capital Requirements There are no special inventory requirements or credit terms extended to customers that would have a material adverse effect on the Company's working capital. (vii) Dependency on a Single Customer No single customer accounted for more than 10% of the Company's total revenues in any of the past three years. (viii) Backlog The Company's backlog of firm orders was $67.2 million and $50.1 million as of December 28, 1996, and December 30, 1995, respectively. The Company believes that substantially all of the backlog at December 28, 1996, will be shipped or completed during 1997. The Company does not 7PAGE believe that the size of its backlog is necessarily indicative of intermediate or long-term trends in its business. (ix) Government Contracts Not applicable. (x) Competition The Company competes in each of its markets primarily on performance, reliability, customer service, and price. In the market for AE and AA spectrometers and ICP/MS instruments, the Company competes primarily with The Perkin-Elmer Corporation and, to a lesser extent, Varian Associates, Inc. The Company competes in the arc/spark market primarily with Spectro. In the FT-IR and FT-Raman markets, the Company competes primarily with Perkin-Elmer; the Digilab division of Bio-Rad Laboratories, Inc.; Bruker Instruments, Inc.; and Bomem Inc. The Company entered the market for UV/Vis instruments with its acquisition of Unicam in 1996. The primary competitors in this market are Perkin-Elmer, Shimadzu, and Hewlett-Packard Co. (xii) Environmental Protection Regulations The Company believes that compliance by the Company with federal, state, and local environmental protection regulations will not have a material adverse effect on its capital expenditures, earnings, or competitive position. (xiii) Number of Employees As of December 28, 1996, the Company employed approximately 2,065 people.
